Urtica dioica (UD), as a natural antioxidant, has positive effects on oocyte maturation. This study aimed to investigate the effects of hydro-alcoholic UD extract and retinoic acid on follicular development in an in vitro fertilization (IVF) condition.

A total of 40 female Wistar rats were randomly divided into 5 groups: group 1 received normal saline, group 2 was given 25 mg/kg retinoic acid, group 3 was administered with 100 mg/kg UD extract, group 4 was treated with retinoic acid plus UD extract, and group 5 received 10 mg/kg olive oil. The histomorphometric parameters were analyzed, including the number of follicles, follicular atrophy, fertilized oocytes, 2-cell embryos, dead embryos, and blastocysts.  

Retinoic acid caused a significant increase in the primary, preantral, and atretic follicles and a substantial decrease in the corpus luteum compared with the control group (p<0.001). The number of preantral, antral follicles, and corpus luteum was significantly higher in group 3 compared with group 1 (p<0.001). Moreover, coadministration of UD plus retinoic acid (group 4) significantly reduced the atretic follicles (p<0.05).

Based on the results, UD herbal extract, as a natural antioxidant agent, could reduce the adverse effects of retinoic acid on oocyte maturation in an IVF condition.

ASGE predictive model for the detection of choledocholithiasis is a reasonable approach for the management of patients with cholelithiasis. Surgeons do not pursue cholecystectomy without evaluation of the biliary system when laboratory tests and diagnostic imaging evidence show biliary duct involvement. Literature revisions reveal that the prediction of choledocholithiasis based on ASGE criteria suffers from poor accuracy which results in unnecessary ERCPs. We decided to estimate the sensitivity and specificity of the ASGE predictive model for the detection of choledocholithiasis with the hope that early EUS would obviate the need for unnecessary ERCPs among highly probable patients for choledocholithiasis based on ASGE criteria.

This is a prospective intervention and control study on the accuracy of ASGE criteria for the prediction of choledocholithiasis. To evaluate the sensitivity and specificity of ASGE criteria, patients were followed in two groups of controls who were treated based on ASGE guidelines and cases who underwent primary EUS. The clinical relevance of the ASGE criteria was estimated by sensitivity and specificity using SPSS Statistics 28 software. Then, absolute risk reduction utilizing primary EUS was also calculated. 

The sensitivity and specificity of the ASGE predictive guideline for choledocholithiasis were estimated to be 62.31% and 51.85%, respectively. Evaluation of the ASGE guideline also revealed that patients in the intermediate probability group who finally required ERCP based on EUS results (false-negatives) were estimated to be 49.1% and patients who were predicted to require ERCP but finally did not need ERCP (false positives) were estimated to be 37.68%. The comparison of the two groups revealed the need for ERCP in about 55.56% of the primary EUS group and 77.42% in the ASGE group. Utilization of primary EUS reduced the need for ERCP by an absolute risk reduction of 0.299. (Primary Endpoint)

ASGE guideline is associated with the overestimation of ERCP in cholelithiasis. The usage of primary EUS will reduce the need for ERCP.

Mood disorders are the most common psychiatric comorbidities in substance users. Mood disorders and substance use disorders are 2 intertwined processes in which treating one aid in treating the other. Depression and substance use disorder are now regarded as major mental health issues due to their widespread incidence.
The study was designed to investigate the prevalence of major depressive disorder (MDD) and bipolar I and II disorders in patients with substance use disorder.  

The participants of this cross-sectional study were 320 patients with substance use disorder based on the DSM–5 (diagnostic and statistical manual of mental disorders 5th edition) criteria in Iran Psychiatric Hospital in 2020, who were assessed using the SCID-5-CV (Structured Clinical Interview for DSM–5 disorders-clinician version), and the demographic and clinical variables questionnaire considering familial and substance use history. The chi-square, Fisher, independent t test, and logistic regression were used to analyze the data.  

Of the patients, 32.8% (n = 105) had mood disorders. The most common mood disorder was MDD (16.9%, n = 54), followed by bipolar I (12.5%, n = 40) and bipolar II (2.8%, n = 9) disorders. Methamphetamine was the most commonly used substance (47.5%, n = 152). Also, 62.5% (n = 200) of participants consumed 2 or more substances simultaneously. The chance of having a mood disorder in married and divorced patients was 2.12 and 2.04 times more than in single patients, respectively.

The lifetime prevalence of bipolar I disorder in patients with substance use disorders is several times more than the general population, thus psychiatrists should pay more attention to mood comorbidities diagnosis and treatment in substance users.

Chronic diseases affect the lives of the patient and caregiver. Caring for a patient with a chronic psychiatric illness, such as bipolar disorder, is a stressful and challenging activity. Caregivers of severe psychiatric patients are the primary victims of violence by patients. Caring for these patients can be very stressful for the caregiver to the extent of experiencing post-traumatic stress symptoms. This study compares the frequency of trauma exposure and PTSD in the caregivers of patients with bipolar disorder type 1(BD-1), bipolar disorder type 1, comorbid post-traumatic stress disorder (BD-1+PTSD), and multiple sclerosis (MS).The MS group served as the control group.  

This cross-sectional study with convenient sampling was conducted at three hospitals in  Tehran, Iran, from April 2020 to January 2022. One hundred eighty caregivers answered a clinical demographic questionnaire. We then used the Trauma History Questionnaire (THQ) to assess the frequency of exposure to different types of trauma. Then, the Persian version of the SCID-5, a valid and reliable instrument for psychiatric diagnoses, was used to diagnose PTSD. Chi-square was used for analyzing data.  

Exposure to trauma has a significant difference between the groups. BD-1 + PTSD patients’ caregivers were exposed to more physical assaults than others (P < 0.0001) There was a significant difference between sexual harassment in the MS group (P = 0.010). There was a significant difference between the three groups in the development of PTSD (P = 0.003). PTSD prevalence in the BD-1 + PTSD caregiver group is more than in other groups. In the caregivers of BD-1+PTSD, the caregiving experience caused traumatic exposure and the development of PTSD in all caregivers. 

This study shows that the prevalence of exposure to traumatic events and PTSD is higher in the caregivers of BD-1 patients, especially if the patient has comorbid PTSD. Detecting these symptoms early and using intervention can make the caregiving burden more tolerable.

One of the key objectives is to update knowledge in order to develop treatment and care recommendations based on research findings. The purpose of the present meta-analysis was to compare the survival rate of narrow dental implants (NDI) with standard dental implants (SDI).  

The international databases targeted for conducting a broad search included PubMed (Medline), Scopus, Web of Sciences, and Embase (Elsevier), which were searched to retrieve articles from January 1, 2000, to the end of July 2022. After the search, studies were screened based on the title, abstract, and full text, and finally, information extraction and quality assessment of the articles were performed based on the Newcastle-Ottawa Quality Assessment Scale checklist. All analyzes were conducted in STATA software Version 17.  

After the screening, 8 retrospective and prospective cohort studies remained in the research for analysis. The outcomes demonstrated that the probability of healthy teeth in the 2 groups of NDI and SDI was not substantially different at least a year after implantation, and the risk ratio of tooth loss in the NDI group was comparable to that of the SDI group (RR, 1.00; 95% CI, 0.98, 1.02; I2: 28.37 %; P = 0.252). In addition, the survival rates in the 2 groups were also measured using meta-analysis and the results showed the survival rates in the 2 groups of NDI and SDI were almost equal. In the SDI group, the survival rate was equal to 94% (95% CI, 90%-98%), and in the NDI group, it was equal to 94% (95% CI, 92%- 98%).  

Based on the results of the present meta-analysis, the survival rates in the both NDI and SDI groups were almost equal.

Universal health coverage (UHC) aims to provide access to basic health services with no financial constraints. In Iran, the major challenges to the implementation of the UHC plan include aggregation and augmentation of resources, something which could threaten the dimension of population coverage and health service delivery. Therefore, this study reviews the strengths and weaknesses of the internal environment as well as the opportunities and threats of the external environment in the UHC plan to help policymakers and decision-makers of the health system.  

In this review study, reputable databases were searched for all the relevant papers on UHC to collect data. After that, the strengths, weaknesses, opportunities and threats (SWOT) analysis was conducted to organize, collect, and analyze data. The SWOT analysis is a process that has 4 components and 2 dimensions. The 4 components are strengths, weaknesses, opportunities, and threats. In fact, strengths and weaknesses are considered internal factors and organizational features, whereas opportunities and threats are considered external factors and environmental features. The listed items were then categorized for clarification and transparency within the framework of the 6 building blocks of the World Health Organization (WHO). 

The relevant studies were reviewed to analyze the strengths and weaknesses of internal environments as well as the opportunities and threats of external environments. The necessary points for better planning and policymaking were then presented.

The success of Iran’s UHC plan can be guaranteed by regular capacity building, ongoing education, and empowerment of society in addition to improving intersectoral collaboration and acquiring political commitment to develop more effective and more accountable systems matching variable and dynamic health requirements.

Superiority of levetiracetam over phenytoin for postcraniotomy seizure prophylaxis in patients with a supratentorial brain tumor is controversial. We aimed to evaluate the efficacy of levetiracetam versus phenytoin for postcraniotomy seizure prophylaxis in supratentorial brain tumor.  

In a randomized controlled trial study, 80 patients with a supratentorial brain tumor who underwent craniotomy were allocated to levetiracetam or phenytoin group, 40 patients each. Seizure prophylaxis was started 5 days before the surgery and continued until 90 days after surgery. Phenytoin group received 100 mg oral phenytoin 3 times a day. The levetiracetam group received 500 mg oral levetiracetam 2 times a day. The primary outcome was the incidence of postcraniotomy seizures. The secondary outcome measure was the safety profile of the drugs.  

All patients of the phenytoin group and 39 patients of levetiracetam completed the study. ‎Two seizures developed in the study population, ‎1 ‏in the ‏phenytoin group (2.5%) and 1 in the levetiracetam group (2.6%) (P = 0.710). Renal or hepatic dysfunction was not observed in any patients. Wound hematoma was seen in 5 patients (12.5%) of the phenytoin and 6 patients (15.4%) of the levetiracetam group (P = 0.481). Skin rash developed in 3 patients (7.5%) of the phenytoin group and no patient of the levetiracetam group (P = 0.132). Thrombocytopenia was detected in 1 patient of the phenytoin group (2.5%) and no patient of the levetiracetam group (P = 0.511). None of the adverse events led to drug withdrawal.  

These results reveal no superiority of levetiracetam over phenytoin for postcraniotomy seizure prophylaxis in supratentorial brain tumor.

Mobile health (m-Health) is a combination of electronic communications and medical information technology that has helped patients and health care workers during the COVID-19 outbreak. This study aimed to aggregate and highlight findings from existing review studies about applications of m-health to prevent COVID-19.  

This scoping review was conducted based on the Arksey and O'Malley framework after searching the PubMed, Web of Science, and Scopus databases from March 2020 to February 2022. Keywords for the search included the English words "Mobile health";" mobile apps"; "corona disease"; "COVID-19"; and "review." Screening of articles was done in 4 stages.  

Out of 37,569 papers found in the search, after the screening and review process, 22 articles were finally selected. From the analysis of the studies, 2 main categories emerged with the titles of "primary preventive applications" and "secondary preventive applications."

M-health is used in both primary and secondary prevention. The m-health tools can be effective in controlling the spread of COVID-19 and improving the treatment process of this disease by providing various pieces of training related to COVID-19 as well as installing various programs to monitor the condition of patients. Also, m-Health can provide services through the exchange of treatment data between health care providers or between patients and health care providers, as well as provide appropriate training for the remote care needs of patients with COVID-19.

Urinary tract infection (UTI) is common after pediatric renal transplantation, and the emergence of multidrug-resistant (MDR) bacteria causing UTI is a therapeutic challenge in this regard. The main purpose of this study was to determine the UTI frequency, its etiologic agents, and the antibiotic susceptibility pattern in the first year following renal transplantation in Iranian pediatric recipients. 

In a retrospective cohort study, all of the 81 children who had undergone renal transplantation in Hazrat Rasoul Akram Hospital between 2012 and 2017 were enrolled. Confirmed episodes of UTI during the first year following renal transplantation were analyzed. The pattern of antibiotic resistance was determined for the causative agents of UTI. The data were analyzed using the IBM SPSS Statistics software (version 20). and the P < 0.05 was considered significant. 

Totally, from 81 enrolled cases, 37(44.7%) cases were in the age group of 11-15 years. Overall, 19, 10, and 3 UTI episodes had occurred in the first month, from the first to sixth month, and between the sixth month and one year after transplantation, respectively. The four most common isolated bacteria were Escherichia coli (E. coli; 31.2%), Pseudomonas aeruginosa (P. aeruginosa; 25%), Enterococci (21.9%) and Klebsiella pneumoniae (K. pneumoniae; 12.5%). The highest rate of resistance was reported to trimethoprim/sulfamethoxazole (TMP/SMX), cephalosporins, and fluoroquinolones among gram-negative bacteria. However, none of the Enterococci isolates were resistant to linezolid and nitrofurantoin.

Resistance to antibiotics is increasing among the pathogens causing UTI in pediatric renal transplanted cases. It is suggested to stop the administration of TMP/SMX and third-generation cephalosporins for empiric treatment of UTI in Iranian pediatric renal transplant recipients. Ciprofloxacin might be administered cautiously secondary to the increasing rate of antibiotic resistance in this group.

The success rate of extracorporeal shock wave therapy (ESWT) in treating epicondylitis, plantar fasciitis, rotator cuff tendonitis, Achilles tendonitis, and Jumper knee has been reported to be 60% to 80%. Most published studies have compared focused ESWT at different intensities with local corticosteroid injection (LCI). We only identified a few studies that specifically compared ESWT with LCI in patients with pes anserine bursitis (PAB). This study aimed to compare the effectiveness of ESWT and LCI in patients with PAB. 

The present study was a randomized clinical trial. Patients diagnosed with PAB who were referred to the physical medicine and rehabilitation clinic underwent a complete physical examination. They (n = 60 patients) were randomly assigned to the ESWT and LCI groups if they met the study criteria. In the ESWT group, 1 ESWT session was performed weekly for 3 consecutive weeks. In the LCI group, 1 injection was performed under an ultrasonography guide. Pes anserine thickness, pain intensity, and treatment satisfaction were measured with visual analog scale (VAS) and quality of life (Short Form–12). A paired-samples t test was used to compare the results obtained in the pre-and posttests. Analysis of variance for repeated measures was used to detect differences over time. The null hypothesis would not be confirmed if the P value was less than the 0.05 level of significance.  

Pes anserine thickness and pain intensity decreased significantly during the study in both groups (P < 0.001). However, the mean difference of pes anserine thickness was more in the LCI group the ESWT group [(-0.6; 95% CI, -1.0 to -0.3) than (-0.1; 95% CI, -0.5, -0.2); P = 0.008]. Also, the mean difference of pain intensity was lower in the ESWT group] than the LCI group [(-2.9; 95% CI, -3.7 to -2.1) (1.0; 95% CI, 0.1to 1.8); P < 0.001]. Patients’ quality of life in both groups increased significantly during the study period (P < 0.001), but the increase in quality of life in patients in the ESWT group (mean difference, 15.3 [95% CI, 10.6-19.9]) was considerably more than in the LCI group (mean difference, -5.3 (95% CI, -10.0 to  -0.6).

Overall, the results of this study showed that both local corticosteroid injections and extracorporeal shock wave therapy are safe and effective in PAB patients.

Health and economy has substantially been influenced by the coronavirus disease 2019 (COVID-19) pandemic. Because of these impacts, household financial contribution to health system is likely to be changed. This study aimed to compare the distribution of household financial contributions before and during the COVID-19 epidemic.  

This is a cross-sectional study. The data were obtained from Iran's Households Income and Expenditure Survey as a national representative survey and included 38,328 households in 2019 (before COVID-19) and 37,577 households in 2020 (during COVID-19 pandemic). The household expenditures deflated according to the Consumer Price Index. The indices of households’ out-of-pocket Payments (OPP), catastrophic health expenditures (CHE), and impoverishment were calculated based on a standard methodology. Data analysis was done using an Excel-based software.  

The households' total expenditures declined for both urban and rural areas during the COVID-19 outbreak. Meanwhile, health expenditure experienced a negative growth rate for urban and rural households at –25.75% and –15.47%, respectively. The average per capita of OOP annually was 1,220,416 ($41.086 PPP) Rials for urban households and 1,017,760 Rials ($34.263 PPP) for rural households in 2020 (the era of COVID-19), which had dropped –30% and –16%, respectively, relative to 2019 (before COVID-19). The proportional share of health service types from the total health expenditure did not change importantly after the onset of COVID-19. The incidence of CHE and impoverishment due to health payments reduced after the onset of COVID-19.  

The households' health expenditures changed considerably during the COVID-19 pandemic and these changes were the same for the urban and rural areas. Despite COVID-19 multi-faceted shocks, the findings of this study showed a slight decline in the incidence of CHE and impoverishment caused by health expenditures. It might be due to forgone health services during the COVID-19 pandemic. Data from these household surveys have some limits to depicting the real effects of this crisis.

This study aimed to compare sublingual misoprostol alone or combined with vaginal Isoniazid (INH) for first-trimester abortion.  

In this randomized controlled trial, 80 pregnant women with missed abortion candidates for first-trimester abortion were randomly assigned to two groups. The first group received 800 μg sublingual misoprostol every three hours maximum for three doses and the second group received 1500 mg vaginal INH followed by the same dose of misoprostol. Vaginal sonography was performed after 24 hours on both groups to observe any retained product of conception. In case of no response or incomplete abortion, the  second course of misoprostol (with the same dose) was administered. The abortion (complete or incomplete) rate was reported within 48 hours after the first dose of misoprostol.  

The rate of successful intervention (either complete or incomplete) abortion within 48 hours of misoprostol administration was 75% in both groups and was not significantly different (P value = 1). Also, hospitalization duration, abortion time, total misoprostol dosage, and the rate of side effects were similar in the two groups. Five patients in the misoprostol group and three in the misoprostol plus isoniazid group underwent emergent D&C because of heavy bleeding.  

A combined regimen of sublingual Misoprostol plus vaginal Isoniazid with the prescribed dosage has similar efficacy to sublingual misoprostol alone in first-trimester abortion.

Local epidemiological data are necessary to identify the disease hot spots and running screening programs. In this study, we evaluated the demographic characteristics of developmental dysplasia of the hip (DDH) in a tertiary referral hospital in Iran.  

In a retrospective study, the medical profiles of 137 DDH children, who were referred to our university hospital between 2014 and 2020, were reviewed for characteristics such as gender, place of birth, age at the diagnosis, gestational age (term or preterm), twin or single birth, mother's age, pregnancy number, breech presentation, associated deformity, family history of DDH, et cetera.  

The study population included 24 (17.5%) boys and 113 (82.5%) girls with a mean age of 2.3 ± 2 years. In the majority of cases (54.2%), it was the firstborn. Twin delivery was seen in only 5 (4.1%) cases. The associated deformity was noticed in 17 (12.4%) patients. Clubfoot was the most commonly associated deformity that was seen in 6 of 17 (35.3%) patients. A family history of DDH was recorded in 12 (8.8%) patients. The breech presentation was recorded in 19 (13.9%) patients. The mean age of the mother at the delivery was 27.2 ± 6.1 years. Tehran, Lorestan, Kurdistan, and Khuzestan provinces had the most referrals.  

DDH is associated with the female sex, positive family history, breech presentation at delivery, clubfoot deformity, and geographic district. These associations could be used for identifying the disease hot spots and running screening programs for earlier detection and better management of DDH.

COVID-19 has become the greatest pandemic of the century. Considering the role of some hematologic and biochemical factors and their alterations due to the activity of the immune system, the current study aimed to evaluate LDH/CRP/ESR/RDW in patients with COVID-19 and their relationship with the severity of lung involvement based on CT scan findings.  

In this cross-sectional study, some biomarkers (LDH/CRP/ESR/RDW) were measured in 158 patients who were admitted to the intensive care unit (ICU) or hospitalized in the infectious diseases ward of Rasoul-e-Akram and Firoozgar hospitals or attended to the outpatient clinics. The diagnosis was confirmed by a positive RT-PCR test in all patients. The severity of lung involvement was determined by CT scan findings for comparison. Data were collected and analyzed through SPSS version 22.  

Regarding the severity of lung damage according to the CT scan, 17.7% of the patients were normal, 19% had less than 25% involvement, 17% had 25% -50% involvement, 33.5% had 50% -75% involvement, and 12% had more than 75% involvement. Considering the increasing severity of lung damage based on CT scans, the levels of RDW, ESR, CRP, and LDH significantly increased in parallel. The diagnostic value of RDW (cut-off point: 12.6, Sen: 73.1% (95%CI: 65.1-79.5), Sp: 53.6% (95%CI: 45.7-61.7), ESR (cut-off point: 49, Sen: 46.9% (95%CI: 38.2-54.5)), Sp: 85.7% (95%CI: 789.-90.5)), CRP (cut-off point: 23, Sen: 62.8%  (95%CI: 54.6-70.4), Sp: 77.7%  (95%CI: 70.3-84.1)) and LDH (cut-off point: 550, Sen: 65.1%  (95%CI: 57.2-72.5), Sp: 85.7% (95%CI: 78.9-90.5)) were significant in diagnosing the severity of lung involvement (P < 0.05). 

The use of RDW, ESR, CRP, and LDH biomarkers could be effective in predicting the severity of lung damage in patients with COVID-19.

Clinical trials were conducted on children on side effects after vaccination. We tried to assess the frequency and onset of the main symptoms in children who were vaccinated. We aimed to evaluate early and delayed adverse effects after coronavirus disease 2019 (COVID-19) vaccine among Iranian pediatrics and adolescents in a national survey.  

This cross-sectional study included people <18 years who received the Soberana (PastoCoVac) and Sinopharm vaccines since 2021. The basic information was gender, age, type of vaccine, and reaction after vaccination besides the main events that occurred for them. The required data were collected via a predetermined checklist by trained interviewers through phone calls by their parents or legal guardians. The independent t test and Fisher exact test were used. P values less than 0.05 were considered significant. 

A total of 11,042 participants (age range, 10-18 years) consisting of 5374 boys (47.8%) and 5768 girls (52.2%) were studied and 88.1% of the children (n = 9727) were vaccinated by Sinopharm and 11.9% (n = 1315) by Soberana. The data of kidney-related side effects had delayed improvement of side effects after the Sinopharm compared with the Soberana vaccines (P = 0.012). Cardiovascular and hematological side effects showed early-onset (P = 0.006) and delayed improvement of side effects (P = 0.002) after the Soberana vaccine compared with the Sinopharm vaccine. Neurological side effects showed delayed improvement of side effects after the Soberana vaccine compared with the  Sinopharm vaccine (P = 0.027). Joint-related side effects showed early-onset (P = 0.004) and delayed improvement of side effects (P = 0.023) after the Soberana vaccine compared with the Sinopharm vaccine. Respiratory side effects showed delayed improvement of side effects after the Soberana vaccine compared with the Sinopharm vaccine (P = 0.013), and dermatological side effects showed early-onset (P = 0.050) and delayed improvement of side effects (P = 0.035) after the Soberana vaccine compared with the Sinopharm vaccine. There was not any statistically significant difference regarding gastrointestinal side effects between the 2 vaccines (P > 0.05).

The cardiovascular and hematological, joint-related (non-neurologic musculoskeletal) and dermatological side effects after the Soberana vaccine appear earlier and end later compared with the Sinopharm vaccine. Improvement of renal side effects in the Sinopharm vaccine group and improvement of neurological and respiratory side effects in the Soberana vaccine group occurred with delay compared with other vaccines.

Heart Failure (HF) imposes a relevant burden and a considerable health concern, with high prevalence and mortality rates. This study was conducted to assess the cost-effectiveness of remote cardiac monitoring with the CardioMEMS Heart Failure System.  

In the present systematic review, several scholarly databases were searched and updated from inception up to September 20, 2022. The objective of the present review was formulated according to the patient/population, intervention, comparison and outcomes format. Mortality rate, hospitalization rate, quality-adjusted life year (QALY), total costs, and the incremental cost-effectiveness ratio regarding the use of the CardioMEMS System were the key outcomes of the present study. The quality of included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS) checklist.  

Finally, 5 articles were retained and analyzed in the present systematic review. All studies employed the Markov and decision tree models. Results show that the CardioMEMS system reduced mortality and hospitalization rate and created a higher QALY. In all selected countries the CardioMEMS method is a more expensive method than the standard of care (SoC), with the highest cost in the United States (US) ($201,437) and the lowest cost in the United Kingdom ($25,963), respectively. the highest willingness to pay in the US and the lowest in Italy ($100,000 and $33,000 per QALY), respectively. Results showed that the most cost per QALY for the CardioMEMS system was in the US and the lowest was in the Netherlands ($46,622 and $26,615 per QALY), respectively.  

In all selected countries, CardioMEMS is a cost-effective method for monitoring and managing pulmonary artery pressures in HF patients. Strategies such as CardioMEMS, which decrease the rate of hospitalization, are likely to be only more cost-effective in the future.

Due to the limited access of clients in non-urban areas to rehabilitation and the difficulty of specialized counseling in such conditions, the need for telehealth services has increased. The purpose of this study is to evaluate the effectiveness of Tele occupational therapy in common disorders of children and adolescents.  

In this systematic review study, a research method published from 2010 to 2022 focusing on the effectiveness of tele-rehabilitation and its impact on children and adolescents with different physical disabilities was done in Google Scholar, PubMed, Scopus and EMBASE databases. 467 articles were obtained in the review, and finally, 18 articles were reviewed. 

In children with CP, Tele occupational therapy will be effective on gross motor function and balance skills, but the impact on the executive function needs more studies. In children with ASD, it will be effective on behavioral problems, but the effect on pro-social behavior needs further studies. In children and adolescents with other movement disorders, it will have an impact on the progress of their physical activity and in children and adolescents with Traumatic Brain Injury (TBI), it will be effective, but the effectiveness of MitiiTM programs needs further studies.  

The findings of this study showed that tele-occupational therapy could be performed in line with face-to-face occupational therapy, and it can lead to the satisfaction of families, but there is still a need to assess the effectiveness of various interventions and tools on different disorders, outcomes and settings.

In order to create a solid evidence base for the development of improved management methods, this study was performed to describe the epidemiology and outcome of nontraumatic lower limb amputations (LLAs).  

This descriptive case series was conducted over a period of 4 years. It included all patients of both sexes and all ages who underwent LLAs for nontraumatic indications.  

There were a total of 217 patients with 136 (62.67%) men and 81(37.32%) women. The age range was 7 to 71 years, with a mean of 54.25 ± 11.49 years.  The most common indication for amputation (41.47%) was diabetic foot gangrene. The most common level of amputation (48.29%) was below knee amputation.  

Patients with diabetic foot gangrene, malignant tumors, and chronic neuropathic ulcers with osteomyelitis constituted the bulk of the amputees. Diabetes mellitus, obesity, and hypertension were the commonest comorbidities identified among them. Public awareness and education would ensure prompt and early health seeking at the appropriate time and help to prevent the need for major amputations in many instances. The amputees' improved reintegration into society and ability to become contributing members of society would be ensured by the provision of vigorous rehabilitation.

Since the function of muscles, and subsequently the mandibular joint, is affected in patients with Bell's palsy, therefore, the evaluation of facial muscles and mandibular function in these patients can be effective in diagnosis, prevention, and treatment planning. The present study aimed to evaluate the degree of displacement and range of motion (ROM) of the mandible and the ability of the facial symmetrical muscles of patients with Bell's palsy.  

This was a quasi-experimental comparative study. The variables evaluated were mandibular movement in a vertical direction and side-to-side displacement. Ten patients with Bell's palsy and 10 healthy eligible volunteers participated in the present study. Three mobile video cameras (to record jaw movements), 9 color markers, Kinovea software, House-Brackmann index, Toledo protocol, and a specialized patient questionnaire were used. Descriptive and inferential statistics were used for data analysis, the Kolmogorov-Smirnov test was used to investigate the normality of data distribution, and independent samples the t test and paired samples t test were used to compare means.  

The maximum lateral on the sound side was 12.40 and 4.49 mm during lateral movements of the patients' mandible, while this value was between 12.30 and 3 mm on the involved side. There is a difference between the affected side and the nonaffected side in terms of the mean lateral movements of the patients' mandible. However, this difference in the mean ROM on both sides is not statistically significant. The maximum mouth opening in healthy individuals during mandibular movements was between 40 and 60 mm, while this value was between 25 and 50 mm in the patients with Bell’s palsy. This study shows a significant difference (P = 0.007) between patients and healthy individuals in terms of the mean of maximum mouth opening (P < 0.05).  

The results of this study showed that the ROM of temporomandibular joint (TMJ) of the patient is the same as that of normal subjects, but the side-to-side motion is more than normal which should be considered in rehabilitation treatments. The present study emphasizes the need to implement a mandibular kinematic evaluation protocol in patients with bell's palsy to prevent damage to the TMJ in the long term.

The highest risk of developing venous thromboembolism (VTE) is seen in patients who have undergone orthopedic surgery. One of the most common methods to reduce the risk of thromboembolism in these patients is anticoagulant prophylaxis. Rivaroxaban is one of the anticoagulants that has a lower cost than other anticoagulants and has a significant effect on people’s quality of life as it is edible. The study aimed to determine the cost-effectiveness of rivaroxaban as compared with enoxaparin for venous thromboembolism prophylaxis in knee replacement   patients in Iran.  

It was a quantitative and economic evaluation study with a cost-effectiveness approach and an applied study because its results could be used directly for policy-making and decision-making in the health system. The study was conducted in 2019 and 2020. This study considered the health system perspective. The study population included all knee replacement patients. The sample included 203 patients referred to Shafa Yahyaeian Hospital and 300 patients referred to Rasoul Hospital in Tehran. The study was conducted in two steps. A systematic review of studies was conducted in the first step. The CHEERS checklist was used to evaluate the quality of the studies in the systematic review. The EQ-5D questionnaire was used in the second step to calculate the QALY, and the cost collection form was used to calculate the direct medical cost. The data were analyzed through a decision tree, and Stata and Tree age pro softwares were the analysis tools. Also, according to the per capita GDP index for Iran in 2018, the incremental cost-effectiveness threshold was considered to be $10,000.  

The results of this study showed that during the prophylaxis period, rivaroxaban was one and a half times less costly than enoxaparin. Quality of life in uncomplicated conditions were 0.85 QALY for rivaroxaban and 0.69 QALY for enoxaparin. Based on the results of this study, the cost of rivaroxaban during the prophylaxis was $ 160.97 and the quality of life was 0.85 QALY and the cost of enoxaparin was $ 276.07 and the quality of life was 0.69 QALY. The cost difference between the two interventions was $ 115.09 and the outcome difference was 0.16 QALY. The incremental cost-effectiveness ratio was $ 189.40 for rivaroxaban and $ 416.28 for enoxaparin. According to the results of this study, rivaroxaban reduced the duration of hospitalization by an average of 2 days in asymptomatic patients (prophylaxis period) compared to enoxaparin. 

Rivaroxaban, an oral medication, reduced costs and increased the quality of life in people undergoing knee replacement surgery compared with an enoxaparin injection vial. This drug was less costly for the patient and health systems and its use was cost-effective as a thromboprophylaxis drug following knee replacement surgery.

The family physician program, as one of the core arms of health care systems, has faced various implementation challenges around the world. Experiences in the implementation of family physician program can be helpful for nations that seek to apply for similar programs. The aim of this study is to systematically review the implementation challenges of family physician program across the world.   

A systematic search was conducted from January 2000 to February 2022 across scientific databases of Embase, MEDLINE, Web of Science, Scopus, CINAHL, EBSCO, and Google Scholar. The Framework approach was used to analyze the selected studies. The quality of the included studies was evaluated using the McMaster Critical Review Form for qualitative studies.  

35 studies upon the study inclusion criteria were included. Based on the Six Building Blocks frame, seven themes and 21 subthemes were developed as the implementation challenges of family physician program. 1) Governance: policy guidance, intelligence, coalition, regulation, system design, and accountability; 2) Financing: financing and payment system; 3) Health workforce: education, research, recruitment and motivation opportunities; 4) Service delivery: management of health services, service package, referral system, continuity of care; 5) Health information systems: production and evaluating the health information system; 6) Availability: provision basic health services, maintenance of facilities; and 7) Cultural considerations: behavior and social determinants of health.  

Scientific governance, financing, and payment mechanisms, workforce empowerment, designing a strong health information system, and providing access to services with cultural considerations can result in the successful implementation of the family physician program in communities.

Helicobacter pylori isa universal pathogen that causes gastric diseases and cancers in humans. In recent years, several virulence genes have been detected in this microorganism. Thus, we aimed to investigate the frequency of Helicobacter pylori strains with cytotoxin-associated gene A(cagA) and outer membrane inflammatory protein A(oipA) genotypes among children and adult patients in Tehran, Iran, and evaluatetheir relation to themanifestations of different clinical symptoms.  

In this cross-sectional study, biopsy specimens were obtained from patients with gastrointestinal symptomsand evaluated for Helicobacter pylori infectionand its genotypes (cagA/oipA) througha polymerase chain reaction PCR assay. Clinical findings and demographic data of patients were documented and analyzed.  

A total of 80 patients with Helicobacter pylori infection were included in the study (34 children and 46 adults). The cagA and oipA genotypes of Helicobacter pylori were identified in 22 (64.7%) and 24 (70.5%) children and in 31 (67.3%) and 34 (73.9%) adults, respectively. These differences were not statistically significant between the 2 studied groups. In addition, the frequency of cagA-positive strains of Helicobacter pylori was found more among patients with gastric ulcers rather than other clinical outcomes.  

Our findings demonstrate a highfrequency of Helicobacter pylori strains with oipA and cagA genotypes among children and adults in this region. Although we could not find a significant relationship between virulence genes and clinical outcomes in the patients, further studies are suggested to evaluate these factors in patients and assess their potential roles in the presence of antibiotic-resistant strains.

Low back pain (LBP), the most common musculoskeletal condition, imposes a significant burden on healthcare and triggers mental and physical disorders. Before surgery, patients are eligible for minimally-invasive treatments, including transforaminal epidural steroid injection (TFESI). We aimed to compare fluoroscopically- and CT-guided TFESI in patients with subacute (4-12 weeks) and chronic (≥12 weeks) LBP.  

In this prospective cohort study, 121 adults with subacute or chronic LBP were recruited. Using propensity score matching (PSM), we created two age, sex, and body mass index (BMI) matched groups of fluoroscopically- and CT-guided TFESI, each including 38 patients. The outcomes of interest were the Oswestry disability index (ODI) and numerical rating scale (NRS), which were measured in all patients before the procedure and at the three-month follow-up. Then, the ODI and NRS mean changes were compared between Fluoroscopy and CT groups using repeated measures ANOVA. All analyses were performed with IBM SPSS Statistics for Windows, version 26 (IBM Corp., Armonk, NY, USA).  

Of the total 76 matched patients with a mean (SD) age of 66.22 (13.49), 81 (66.9%) were female. ODI and NRS scores significantly decreased from baseline to the three-month follow-up in both treatment groups. The ODI score mean change from baseline to follow-up compared between the two groups was insignificant (fluoroscopy vs. CT mean difference (95% CI): 1.092 (-0.333-2.518), P = 0.131). Similarly, the NRS score mean change from baseline to follow-up compared between the two groups was insignificant (fluoroscopy vs. CT mean difference (95% CI): -0.132 (-0.529-0.265), P = 0.511).  

Fluoroscopically- and CT-guided TFESI show similar therapeutic effectiveness in patients with subacute and chronic LBP.

Despite the existing literature on the effect of spirituality on health, lack of consensus on definition and evaluation methods are major barriers to applying the results of these studies. In this scoping review, we intend to identify the instruments used for evaluating spirituality in health in Iran and evaluate their domains. 

We searched PubMed, Scopus and Web of Science, Islamic World Science Citation Center, Scientific Information Database, and Magiran between 1994 and 2020. We then identified the questionnaires and searched for the original article reporting the development or translation, as well as the psychometric evaluation process. We extracted data on their type (developed/translated), and other psychometric properties. Finally, we categorized the questionnaires accordingly.

After selecting the studies and evaluating the questionnaires, we identified 33 questionnaires evaluating religiosity (10 questionnaires), spiritual health (8 questionnaires), spirituality (5 questionnaires), religious attitude (4 questionnaires), spiritual need (3 questionnaires) and spiritual coping (3 questionnaires). Other existing questionnaires had issues in the development or translation process or lacked reported psychometric evaluations. 

Many questionnaires have been used in spiritual health studies in the Iranian population. These questionnaires cover different subscales according to their theoretical base and the developers’ perspectives. Researchers should be informed about these aspects of the questionnaires and select the instruments meticulously based on the aim of their study and the characteristics of the questionnaires.

The increasing incidence of papillary thyroid carcinoma (PTC) and the inadequacy of routine histologic examination in its diagnosis necessitate the application of ancillary studies like immunohistochemistry. This research aimed to investigate the scoring system and diagnosis of PTC with cytokeratin 19 (CK19), human bone marrow endothelium marker-1 (HBME-1), and galectin-3.  

This experimental laboratory study was performed at Babol University of Medical Sciences, Mazandaran, Iran from April 2017 to March 2019. Neoplastic and nonneoplastic tissue samples of 100 cases with a diagnosis of PTC were selected by convenience sampling. CK19, HBME-1, and galectin-3 immunohistochemistry markers were used on tissue samples. Analysis was performed using the t test and the chi-square test, as well as the receiver operator characteristic (ROC) curve (significance level P < 0.05).  

The CK19 staining was observed in all 100 (100%)  non-neoplastic tissues, but HBME-1 and galectin-3 were positive in 36 (36%) and 14 (14%) of non-neoplastic tissues, respectively. The intensity scores of all the markers and their total had significantly different means in PTC and non-neoplastic tissues (P < 0.001). A significant difference was observed between the total score of each marker and the total score of their combination (P < 0.001). The combination of all 3 markers with an 11.5 0 cut-off for the total score showed the most sensitive (0.99) and specific (1.00) results.  

Interpreting CK19, HBME-1, and galectin-3 with the aid of the proposed scoring system was fruitful. HBME-1 and galectin-3 can be used individually or in combination for the diagnosis of PTC.

Gamification is the process of game thinking and game mechanics to attract learners and solve problems. It is a unique growing phenomenon in education and training programs. Educational games, by application of game design and game elements in learning environments, motivate students to learn and improve the teaching and learning process. Herein, this scoping review presents an overview of the theoretical underpinnings of gamification that is crucial in understanding the theoretical pillar of successful educational games.  

This scoping review follows Arksey and O’Malley’s stages of scoping review. In this review, the gamification in medical education articles that implicitly or explicitly presented underpinning learning theories of gamification in medical education was retrieved. So, keywords such as gamification, learning theories, higher education, and medical education were searched in Scopus, PubMed, WEB OF SCIENCE, EMBASE, ERIC, and Cochrane Library from 1998 to March 2019.  

The search indicated 5416 articles which were narrowed down by title and abstract relatedness. 464 articles entered the second phase of the study and after reviewing their full text, finally, 10 articles which were explicitly and implicitly reported the underpinning learning theories remained.  

Gamification is a strategy using game design techniques for non-game experiences for more effective learning and provides a more attractive environment for teaching and learning. Designing gamification based on learning theories (behavioral, cognitive, and constructivist), makes them more efficient, and the application of learning theories in designing gamification is recommended.

According to the worldwide increasing prevalence of non-alcoholic fatty liver disease (NAFLD), the present study aimed to investigate the mechanism effects of saffron consumption on preventing NAFLD in a rat model.

In an experimental study, 12 rats were randomly divided into 2 groups to be evaluated in the prevention phase for 7 weeks. In the prevention phase, the animals were randomly assigned to either fed HFHS + 250 mg/kg saffron (S) or fed with HFHS. Afterward, parts of the liver were excised for histopathologic examination. Plasma concentrations of ALT, AST, GGT, ALP, serum lipids, insulin concentrations, plasma glucose, hs-CRP, and TAC were measured. Moreover, Also, the gene expression of 6 target genes was evaluated, including FAS, ACC1, CPT1، PPARα ،DGAT2, and SREBP 1-c at the beginning and end of the study. Also, the differences among groups were evaluated by the Mann-Whitney test for non-normal data and the independent t test for normal data.

The prevention phase groups have a significant elevation in body weight (P = 0.034) and food intake (P = 0.001) of the HFHS group versus HFHS + 250 mg/kg S group. Also, there was a significant difference between groups 1 and 2 for ALT (P = 0.011) and AST (P = 0.010), and TG (P = 0.040). The HFHS group had higher plasma levels of FBS (P = 0.001), insulin (P = 0.035), HOMA-IR (P = 0.032), and lower TAC (P = 0.041) versus the HFHS+ S group. Also, the difference between HFHS + 250 mg/kg S and HFHS for PPARα gene expression was significant (P = 0.030).

The present study showed that consumption of saffron could prevent developing NAFLD in rats at least partially through modulation in gene expression of PPARα.

Health care workers (HCWs) are at the frontline of the fight against the coronavirus disease 2019 (COVID-19). Long COVID is defined as “the persistence of some symptoms of COVID-19, more than 4 weeks after the initial infection.” The aim of the present study was to investigate the prevalence of long COVID status among HCWs in the largest hospital complex of Iran.  

In this cross-sectional study, all patients with COVID-19 who had taken sick leave were included in the study (n = 445).  Data regarding sick leave characteristics were collected from the records of the nursing management department of the hospital. Study variables included demographic and occupational information, variables related to mental health assessment, organ systems involved in COVID-19, and duration of symptoms. Frequencies, percentage distributions, means, standard deviation, and range (minimum, maximum) were used as descriptive analysis methods. Associations between symptoms’ persistency and clinical characteristics were assessed by  logistic and linear regressions.  

Age, N95 mask use, and respiratory protection significantly contributed to the persistence of COVID-19 symptoms (P < 0.05). The prevalence of long COVID among HCWs was 9.44% among 445 participants. The loss of taste persisted longer than the other symptoms before returning to normal.  Among the postrecovery complications asked, anxiety was the most common persistent mental symptom (58.5%), followed by gloomy mood (46.3%) and low interest (46.2%), respectively.  

HCWs with COVID-19 symptoms had prolonged symptoms of COVID-19 that can affect their work performance, thus, we recommend evaluating COVID-19 symptoms in HCWs with infection history.

People with waterpipe tobacco smoking (WTS) seem to be more at risk for the serious complications of coronavirus disease 2019 (COVID-19). This study aimed at assessing the behavioral intention (BI) of WTS by women in the COVID-19 pandemic and its contributing factors.  

This cross-sectional descriptive-correlational study was conducted in 2020 (ie, during the COVID-19 pandemic). Participants were 300 women randomly selected through multistage sampling from comprehensive healthcare centers in Khorramabad, Iran. Data collection instrument was a 42-item questionnaire with 4 main subscales, namely knowledge, attitude, differential association, and BI. Data were collected through both online and phone-based methods and were analyzed using non-parametirc path analysis.  

The prevalence of WTS among women was 13% (95% CI, 11.06-14.94) and the mean scores of attitude, differential association, and behavioral intention among participants with WTS were significantly higher than participants without WTS (P < 0.001). Moreover, 46.12% (95% CI, 38.12-54.08) of participants with WTS reported intention to quit WTS due to the COVID-19 pandemic and 43.6% (95% CI, 35.66-51.54) of women with WTS and 16.5% (95% CI, 14.20-18.80) of women without WTS believed in the protective effects of WTS against COVID-19. The path analysis model showed that the BI of WTS had a significant inverse relationship with knowledge and a significant direct relationship with attitude and differential association.  

This study suggests the need for quality educational and counseling interventions for the general public to correct popular misconceptions about the protective effects of WTS against COVID-19.

Implementing bibliometric indicators is the most prominent way to quantify the current status of research performance. This study aimed to map out the research performance of Iranian medical academics and universities in 2020 and determine its progress from 2016.  

Data were extracted from the Iranian scientometric information database and universities’ scientometric information database. Then, the data were analyzed to provide descriptive statistics of bibliometric indicators. Besides, the association between the research productivity of academics or universities with their background characteristics was investigated using Mann-Whitney U, Kruskal-Wallis, and chi-square tests.  

Iranian medical academics had extensive research productivity from 2016 to 2020, leading to 2.5-fold increase in their median number of papers. The research productivity was heterogeneous among the academics, with an H-index ranging from 0 to 98, and a median of 4. The research productivity was different by gender, academic position, general field of study, and academic degree. The class 1 universities had a higher quantity in research performance; however, there was no difference in quality-related indices comprising citations per paper ratio and high impact publication rate (SJR Q1) among different university classes. The median international collaboration rate has followed a growing trend in recent years and was 17% in 2020.  

There is a remarkable growth in the research productivity of Iranian academics and universities. Iranian research community historically had rare international research collaborations; however, promising growth is shown in this regard. To maintain the growth in research productivity, the country should increase research and development expenditure, address gender disparities, supply universities that are lagging behind, facilitate further international collaboration, and support national journals to be indexed in the international citation databases.

Medical education system in Iran has an essential role in responding to scientific development targets from both education and research perspectives. Investigating future trends and analyzing how they interact with the medical education system helps increase awareness and give insight into the preferred future.   

The present qualitative study consists of Systematic reviews and interviews that have been analyzed using content analysis. Afterward, the themes and codes were visualized in the form of maps and presented in a focus group discussion of experts to define how medical education trends will impact scientific development. 

The future trends of Iran's medical education system were classified into six groups: workplace changes, demographic changes, changes in concepts, the emergence of new players, structural changes in universities, and technology development. The next point is how they will influence science development. Their impact on science development is classified into five main groups or main streams of change of new financial models, open science, redesigning the research management, the role of universities, and capacity building.

Our findings showed that redesigning the structure of medical education is the most important priority to make the system as agile as needed to capture the signs and act. New meanings and concepts should also be considered in restructuring, like power balance, competency-based and personalized education, cost-effectiveness, and openness.

This study aims to map the research trends in the field of stem cell research in Iran by presenting a systematic and analytical bibliometrics approach based on data from the Web of Science database.  

In this study, we provide a visualization overview of the distribution of stem cell publications in Iran. The HistCite software was used to draw and analyze the historiographical maps, based on Global Citation Score (GSC) and Local Citation Score (LCS) in order to indicate the most frequent thematic trends. The accuracy of clustering and classification of scientific fields is enhanced by the incorporation of algorithms and main bibliometric analysis.  

A total of 5123 records were collected from the Web of Science database in 2020. The most prolific author had a GCS of 5890 and the most productive university earned GCS of 13677. “Cell Journal,” with 186 records contributed the highest number of publications. The highest cited document based on GSC had a score of 646 and the highest cited article based on LCS had a score of 71. We documented regular growth in outputs. In addition, the scientific maps based on LCS and GCS have been drawn. The prominent, distinguished areas of study revolve around differentiation, generation, proliferation, and the therapeutic use of stem cells as well as “genotoxicity in stem cells”, “mesenchymal stem cells” and “embryonic stem cells”.  Journal articles were the predominant document type.  

Research on stem cells is a biomedical venture with great scientific impact, and its development in Iran is undeniable. This study provides an overview and a framework for the weaknesses and strengths of Iranian research outputs on stem cells, representing the main clusters in scientific maps. We hope that our results help researchers to plan future studies and promote their research productions.

Forward Head Posture (FHP), which refers to the head being more forward than the shoulder, is one of the most common postural defects of all ages. Therefore, in this study, we aimed to compare the effectiveness of exercise therapy and electroacupuncture in patients with FHP and myofascial pain syndrome (MPS).  

The present study was an open-label randomized clinical trial. A total of 61 patients with FHP and MPS who were referred to the physical medicine clinic of Besat Hospital between 2020 and 2021 were analyzed. Patients in one group were treated with electroacupuncture, and another one was treated with exercise therapy. The primary outcomes were FHP angles (CVA, CA, and shoulder angle), pain intensity (VAS), and quality of life (SF-12). Paired t-test was used to compare the results obtained in the pre-test and post-test. To detect differences over time, the analysis of variance models was used to repeat the observations. If the p-test result is less than the test significance level of 0.05, the null hypothesis is not confirmed.  

The rate of final CVA and increase in CVA in the exercise therapy group were significantly higher than in the electroacupuncture group (P < 0.001). The average shoulder angle in the exercise therapy group increased from 47.1° ± 3.0° to 51.9° ± 3.3° (P < 0.001) and in the electroacupuncture group from 47.9° ± 3.1° to 51.0° ± 2.8° (P < 0.001). A significant difference was observed between the two groups in terms of pain intensity changes during the study.  

Overall, the results of this study showed that both exercise therapy and electroacupuncture significantly improved patients' posture, reduced pain intensity, and increased quality of life in FHP patients with MPS; But exercise therapy was more effective in improving FHP angles and electroacupuncture was more successful in reducing patients' pain intensity.

During the COVID-19 pandemic, patients with diabetes are among the most vulnerable. Our purpose is to research the dynamics of morbidity, mortality, and survival of patients with diabetes in Kazakhstan before and during the current pandemic.  

The indicators were calculated taking into account gender and nosological forms (E10-E14, according to ICD-10).The survival analysis was performed by the method of constructing survival tables and the Kaplan-Meier method. Based on methods, the official reporting data of 1,903,243 cases of diabetes and 20,605 deaths from diabetes were analyzed for the period 2018-2021.

In Kazakhstan, during the COVID-19 pandemic, there has been an increase in the absolute frequency of all cases of diseases by 1.8 times (716,048 in 2021 against 396,990 in 2018) and newly detected by 2.0 times (from 38,396 to 75,027), also prevalence by 1.7 times (3743.9 in 2021 against 2142.2 in 2018) and incidence E10-E14 by 1.9 times (392.3 in 2021 against 207.2 in 2018). Mortality from E10-E14 in Kazakhstan increased during the pandemic by more than 1.5 times (34.1 per 100,000 in 2021 against 22.3 per 100,000 in 2018), and the average survival time at E10-E14 shifted (from 69.8 to 70.5 years) (P = 0.001).

To a greater extent, the increase in diseases and terminal outcomes occurred due to non-insulin-dependent type (E11) diabetes, mainly in the female population.

Lockdowns due to the coronavirus disease 2019 (COVID-19) pandemic forced many dental offices to be closed. This study aims to investigate the association between COVID-19 imposed lockdowns and online searches for toothache using Google Trends (GT).  

We investigated GT online searches for the term “toothache” within the past 5 years. The time frame for data gathering was considered as the initiation and end dates of national/regional lockdowns in each country. We used 1-way analysis of variance to identify statistical differences in relative search volumes (RSVs) between 2020 and 2016-2019 for each country.

Overall, 16 countries were included in our analyses. Among all countries, Indonesia (n = 100), Jamaica (n = 56), Philippines (n = 56), Iran (n = 52), and Turkey (47) had the highest RSVs for toothache in the specified period. Compared with the previous 4 years, higher RSVs were seen in the world (as a whole) (2020 RSVs, 94.4; vs 2019 RSVs, 77.8 [P < 0.001]) and 13 countries (81.3% of the included countries). 

Generally, searching for the term “toothache” showed an increase during the COVID-19 lockdowns in 2020 compared with the past 4 years. This can imply the importance of dental care as urgent medical care during public health emergencies such as COVID-19.

The number of available musculoskeletal tumor registries is relatively small. We developed a registry system focused on the clinical aspects of musculoskeletal tumors to improve quality of care indexes through the development of updated national protocols. In this study, we describe our protocol, challenges, and the data collected during the implementation of the registry system in a single-specialty orthopedic center in Iran.  

Three main malignant bone tumors, including osteosarcoma, Ewing sarcoma, and chondrosarcoma, were included in the registry. After establishing a steering committee, we defined the minimum data set based on a literature review and suggestions from an expert panel. Accordingly, the data collection forms and the web-based software were developed. The collected information was categorized into 9 classes, including demographics, socioeconomic data, signs and symptoms, past medical history, family history, laboratory tests, tumor characteristics, primary treatment, and follow-up. Data collection was performed both retrospectively and prospectively.  

Until September 21, 2022, a total of 71 patients were registered (21 patients prospectively and 50 patients retrospectively) and consisted of 36 (50.7%) cases of osteosarcoma, 13 (18.3%) cases of Ewing sarcoma, and 22 (31%) cases of chondrosarcoma. The implementation of the registry demonstrated promising data regarding the tumor characteristics, delay patterns, and socioeconomic status of the patients. 

The main lessons learned were to develop a monitoring system to make sure that the new staff is adequately trained for the registration process as well as avoid the inclusion of time-consuming useless data in the minimum data set.

Different devices have diverse accuracy in diagnosing glaucoma, and therefore choosing the best device is challenging. Thereby, this study was conducted to evaluate the diagnostic sensitivity and specificity of imaging devices in glaucoma and explore the need for an updated meta-analysis on this issue.  

In this systematic review and meta-analysis, PubMed, Scopus, and Web of Science databases were searched for articles published between January 2004 and 2022. Cross-sectional or diagnostic studies were selected, and sensitivity, specificity, positive predictive value, and negative predictive value were measured. 

A total of 28 cross-sectional studies were included for meta-analysis. Devices were divided into 2 groups, based on the optic nerve area and the macular area. For the nerve area, the pooled sensitivity was 77% (CI 95%, 70-83; I2, 90.01%) and the pooled specificity was 89% (CI 95%, 84-92, I2, 93.22%), and for the macular area, the pooled sensitivity was 87% (CI 95%, 80-92, I2, 91.79%), and the pooled specificity was 90% (CI 95%, 84-94; I2, 86.30%). We analyzed each device separately. For optical coherence tomography(OCT), the pooled sensitivity was 85% (CI 95%, 81-89; I2, 87.82%) and the pooled specificity was 89% (CI 95%, 85-92; I2, 84.39%); for Heidelberg retinal tomography (HRT), the pooled sensitivity was 72% (CI 95%, 57-83; I2, 88.94%) and the pooled specificity was 79% (CI 95%, 62-90; I2, 98.61%), and for optical coherence tomography angiography (OCTA), the pooled sensitivity was 82% (CI 95%, 66-91; I2, 93.71%) and the pooled specificity was 93% (CI 95%, 87-96; I2, 64.72%).  

The macular area was more sensitive and specific than the optic nerve head. Furthermore, OCT had higher sensitivity, and OCTA had higher specificity when compared with other imaging devices.

Paying attention to moral issues is one of the essential requirements of medical practice, and moral aspects must be considered in making decisions to achieve the desired results and ensure the patient’s satisfaction. Moral sensitivity is one of the components that enable physicians to act ethically in their decisions. Since medical students must acquire the necessary skills to deal with patients properly in clinical courses, the current paper examines the moral sensitivity of medical students in both preclinical and late clinical courses.  

This is a cross-sectional study performed on 180 medical students in the preclinical and late clinical course. The study tool is an adapted version of the Kim-Lutzen ethical sensitivity questionnaire with 25 items and Likert scoring 0-4. The obtained score can be between 0-100. Data was analyzed using SPSS25. Statistical t-test or its non-parametric equivalent (Mann-Whitney) was used for quantitative variables and Chi-square or Fisher exact tests were used for qualitative variables. Pearson's correlation coefficient was used to measure the correlation of the variables.  

The mean age of stagers and interns was 22.7 + 0.85, and 26.5 + 1.11. 41 (51.2%) of stagers and 51 (63.7%) of interns had a history of participating in workshops related to medical ethics, and 4 (5%) of the former and 3 (3.8%) of the latter had previously conducted research in the field of medical ethics. there was a significant relationship between the stagers’ history of conducting research in the field of ethics and their moral sensitivity. Concerning moral sensitivity components, the highest scores belonged to “altruism and trustworthiness”, “the use of moral concepts in moral decisions”, and “respect for the patient’s autonomy” in both groups., 95% of stagers and 98.8% of interns had medium level (51-75) of moral sensitivity.  

Medical students’ moral sensitivity did not increase significantly during the clinical course. It is necessary to review and reconsider medical ethics educational methods, the time allocated to relevant courses, and the practical need for clinical education in addition to theory. Directing research projects and student dissertations toward topics related to medical ethics can also contribute significantly to enhancing moral sensitivity.

Neurostimulation is one of the new therapeutic approaches in patients with drug-resistant epilepsy, and despite its high efficiency, its mechanism of action is still unclear. On the one hand, electrical stimulation in the human brain is immoral; on the other hand, the creation of the epilepsy model in laboratory animals affects the entire brain network. As a result, one of the ways to achieve the neurostimulation mechanism is to use epileptiform activity models In vitro. In vitro models, by accessing the local network from the whole brain, we can understand the mechanisms of action of neurostimulation.  

A literature search using scientific databases including PubMed, Google Scholar, and Scopus, using "Neurostimulation" and "epileptiform activity" combined with "high-frequency stimulation", " low-frequency stimulation ", and "brain slices” as keywords were conducted, related concepts to the topic gathered and are used in this paper.  

Electrical stimulation causes neuronal depolarization and the release of GABAA, which inhibits neuronal firing. Also, electrical stimulation inhibits the nervous tissue downstream of the stimulation site by preventing the passage of nervous activity from the upstream to the downstream of the axon.  

Neurostimulation techniques consisting of LFS and HFS have a potential role in treating epileptiform activity, with some studies having positive results. Further investigations with larger sample sizes and standardized outcome measures can be conducted to validate the results of previous studies.

Serum albumin can function as a potential biomarker to determine the severity of the injury and clinical staging of children with burns. Therefore, in this study, we investigated the association between serum albumin level and complications and mortality rate in children with burns.  

In this descriptive-analytic cross-sectional study, 85 patients younger than 18 years with burns who were admitted to Shahid Motahari hospital between 2021 and 2022 were studied. Demographic information, including patients' age, sex, weight, underlying diseases, medical information, albumin level, and C-reactive protein (CRP), was obtained from patient records. Patients were observed until discharge. The independent t-test, chi-square, Pearson correlation, and logistic regression were used for analysis and to examine the predictive role of albumin.  

Out of 85 patients, 47 and 38 were boys and girls, respectively. The mean age of the participants was 3.69 ± 3.09 years. The mean length of hospital stay was 2.3 days, with a median of 1.5 days. The mean percentage of burns was 23.44 ± 16.50, and burn grade 2 was the most common. A total of 25 patients (29.41%) were admitted to the intensive care unit (ICU), and 13 deaths (15.29%) were observed among the patients. The mean albumin level was significantly lower than in other patients with outcomes of pulmonary infection, sepsis, renal failure, ICU admission, and death (P < 0.001).  

Serum Albumin has a significant predictive value in death, pulmonary infection, sepsis, admission to the ICU, and renal failure. Serum albumin may be a good prognostic marker associated with morbidity and mortality.

Non-communicable diseases as a leading cause of death have a surveillance system in most countries. This is disturbed by the emergence of coronavirus disease-2019 (COVID-19) in December 2019. In this regard, health system managers at decision-making levels tried to overcome this problem. Therefore, strategies to deal with this issue and bring the surveillance system to an ideal state were proposed and considered.

During the pandemic of COVID-19, the function and performance of hospitals have been affected by various economic-financial and management aspects. The aim of the current study was to assess the process of therapeutic care delivery and also the economic-financial functions of the selected hospitals before and after COVID-19.  

This research is a descriptive-analytical study and a cross-sectional-comparative study in terms of time, and it was conducted in several selected teaching hospitals of Iran University of Medical Sciences. A purposeful and convenient sampling method was used. The data has been collected using the standard research tool (standard checklist of the Ministry of Health) in the two areas of financial-economic  and healthcare performance (such as Data of financial and economic indicators such as direct and indirect costs, liquidity ratio and profitability index as well as key performance indicators of hospitals such as bed occupancy ratio (BOR; %), average length of stay (ALOS), bed turnover rate (BTR), bed turnover distance rate (BTIR) and hospital mortality rate (HMR), physician-to-bed ratio and nurse-to-bed ratio) of hospitals in two times before and after the outbreak of COVID-19 (time period 2018 to 2021). The data was collected from 2018 to 2021. Pearson/Spearman regression was used for the evaluation of the relationship between variables using SPSS 22.  

This research showed the admission of COVID-19 patients caused a change in the indicators we evaluated. ALOS (-6.6%), BTIR (-40.7%), and discharge against medical advice (-7.0%) decreased from 2018 to 2021. BOR; % (+5.0%), occupy bed days (+6.6%), BTR (+27.5%, HMR (+50%), number of inpatients (+18.8%), number of discharges (+13.1%), number of surgeries (+27.4%), nurse-per-bed ratio (+35.9%), doctor-per-bed ratio (+31.0%) increased in the same period of time. The profitability index was correlated to all of the performance indicators except for the net death rate. Higher length of stay and turnover interval had a negative effect on the profitability index while higher bed turnover rate, bed occupancy ratio, bed day, number of inpatient admission, and number of surgery had a positive effect on the profitability index.  

It has been shown from the beginning of the COVID-19 pandemic, the performance indicators of the studied hospitals were negatively affected. As a consequence of the COVID-19 epidemic, many hospitals were not able to deal with the negative financial and medical outcomes of this crisis due to a significant decrease in income and a double increase in expenses.

The high reliance on out-of-pocket (OOP) payments for health financing in Iran have been led to different inequity problems such as catastrophic health expenditure (CHE) and impoverishment. This scoping review has been conducted to understand the variations in CHE and impoverishment, the underlying determinants of CHE, and its inequality in the past 20 years.  

This scoping review is guided by Arksey and O’Malley’s scoping review framework. systematically PubMed, Scopus, Web of Science, ProQuest, Scientific Information Database, IranMedex, IranDoc, Magiran Science, Google Scholar, and grey literature were searched systematically from 1 January 2000 to August 2021. We included studies that reported the rate of CHE, impoverishment, inequality, and its influencing factors. Simple descriptive statistics and narrative synthesis were used to present the review findings.  

From 112 included articles, the average incidence of CHE was 3.19% at the 40% threshold, and about 3.21% of the households had impoverished. We found an unfavorable status of health inequality indices, including the average of fair financial contribution (0.833), concentration (-0.01), Gini coefficient (0.42), and Kakwani (-0.149). The most widely applied key drivers influencing the rate of CHE in these studies were household economic status, place of residence, health insurance status, household size, head of the household’s gender, education level and employment status, having a household member under 5/ above 60 years old, with chronic diseases (in particular cancer and dialysis), disability, using inpatient and outpatient and dentistry services, medicines and equipment, and low insurance coverage.  

The result of this review calls for intensifying health policies and financing structures in Iran to provide more equitable access to all populations, especially the poorest and vulnerable. Moreover, the government is expected to adopt effective measures in inpatient and outpatient care, dental services, medicines, and equipment.

Large-volume paracentesis has become the first treatment choice for patients with severe and refractory ascites. The studies have reported several complications after therapeutic paracentesis. But there are few published data on the complications with or without Albumin therapy.  We aimed to analyze the safety and complications of large-volume paracentesis in children with or without albumin therapy.  

This study was conducted on children with severe ascites with chronic liver disease who underwent large-volume paracentesis. They were divided into albumin-infused and albumin non-infused groups. In the case of coagulopathy, no adjustment was made. Albumin was not administered after the procedure. The outcomes were monitored to evaluate the complications. To compare two groups, a t-test was utilized, and the ANOVA test was used to compare several groups. If the requirements for using these tests were not met, Mann-Whitney and Kruskal-Wallis tests were applied.  

Decreased heart rate was observed in all time intervals and was meaningful six days after paracentesis. MAP also decreased statistically at 48 hours and six days after the procedure (P < 0.05). Other variables did not show any meaningful change. 

Children having tense ascites with thrombocytopenia, prolonged PT, Child-Pugh class C, and encephalopathy can undergo large-volume paracentesis without any complication. Albumin administration before the procedure in patients with low levels of Albumin (<2.9) can effectively overcome the problems of tachycardia and increased mean arterial pressure. There will be no need for Albumin administration after paracentesis.

The accurate diagnosis of cardiac disease is vital in managing patients’ health. Data mining and machine learning techniques play an important role in the diagnosis of heart disease. We aimed to examine the diagnostic performances of an adaptive neuro-fuzzy inference system (ANFIS) for predicting coronary artery disease and compare this with two statistical methods flexible discriminant analysis (FDA) and logistic regression (LR).  

The data of this study is the result of descriptive-analytical research from the study of Mashhad. We used ANFIS, LR, and FDA to predict coronary artery disease. A total of 7385 subjects were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. The data set contained demographic, serum biochemical parameters, anthropometric, and many other variables. To evaluate the ability of trained ANFIS, LR, and FDA models to diagnose coronary artery disease, we used the Hold-Out method.For analyzing data, we used SPSS v25, R 4.0.4, and MATLAB 2018 software.  

The accuracy, sensitivity, specificity, Mean squared error (MSE)‎ , and area under the roc curve (AUC) for ANFIS were 83.4%, 80%, 86%, 0.166 and 83.4%. The corresponding values based on the LR method were 72.4%, 74%, 70% , 0.175 and 81.5% and for the FDA method, these measurements were 77.7%, 74%, 81%, 0.223, and 77.6%, respectively.  

There was a significant difference between the accuracy of these three methods. The present findings showed that ANFIS was the most accurate method for diagnosing coronary artery disease compared with LR and FDA methods. Thus, it could be a helpful tool to aid medical decision-making for the diagnosis of coronary artery disease.

The dynamic and systemic planning and targeting in the health system require attention to all the system's components and investigation of their causal relationship in order to form a clear view and image of it. Therefore, the present study was designed with the aim of identifying the comprehensive dimensions of the system within a specific framework.  

Key components in the health system were identified through the scoping review method. For this purpose, 61 studies with selected keywords were extracted from international databases, including Scopus, Web of Science, PubMed and Embase, and Persian language databases including Magiran and SID. Inclusion and exclusion criteria in this study were languages, time range, repeated studies, studies related to the health system, appropriateness of studies with the subject and purpose of the present study and the method used. The content of the selected studies and extracted themes were analyzed and categorized in the Balanced Scorecard (BSC) framework.  

In health system analysis, key components were divided into 18 main categories and 45 categories. Also, they were categorized according to the BSC framework into five dimensions of population health, service delivery, growth and development, financing, and governance & leadership.  

For health system improvement, policymakers and planners should consider these factors in a dynamic system and a causal network.

Mental health is integral to public health in adolescents. Although previous studies have shown that low socioeconomic status (SES) is associated with mental disorders (MD), it is unclear which mental health domains are most important. Thus, our study aimed to investigate the associations between 5 domains of mental disorder and SES inequality in adolescents. 

We conducted a cross-sectional study among adolescents (N = 1724). Associations between SES inequality with mental disorders, such as emotional symptoms, conduct problems, hyperactivity, peer relationship problems, and prosocial behavior, were examined. We used the concentration index (CI) to determine inequality. The gap between the low and high socioeconomic groups was decomposed into its determinants using the Blinder-Oaxaca decomposition method.  

Mental health's overall CI was –0.085 (P ˂ 0.001). The emotional problem was primarily caused by SES inequality (–0.094 [P = 0.004]). Decomposition of the gap between the 2 economic groups showed that physical activity, school performance, exercise, parents' smoking status, and gender were the most important determinants of inequality.  

SES inequality plays a vital role in adolescents' mental health. It seems that the emotional problem domain of mental health might be more amenable to interventions than other domains.

Iran has implemented the Family Physician Program (FPP) in 2005 in 4 provinces. This program was supposed to be expanded across the country; however, it faced various challenges. Considering the impact of the referral system on the quality of the FPP implementation, different studies were conducted to evaluate the performance of this system. Therefore, this systematic review of the literature was conducted to investigate the challenges of the referral system of the FPP in Iran.  

All published original articles, reviews, or case studies published in English or Persian related to the challenges in the referral system FPP in Iran from 2011 to September 2022 were included in this study. International credible scholarly databases were searched. The search strategy was defined based on keywords and the search syntax.  

Out of 3910 articles identified by the search strategy, considering the inclusion and exclusion criteria and relevance of the study, and accreditation of the studies, 20 studies were included. The referral system suffers from different challenges in the areas associated with policy and planning, management, referral process, and health service recipients.  

The inefficient gatekeeping role of family physicians was one of the most important challenges of the referral system. The referral system should be improved by having evidence-based guidelines and policy documents, unified stewardship, integrated insurance schemes, and effective communication between different levels of care.

The coronavirus disease 2019 (COVID-19) pandemic at the end of 2019 posed a global health concern. It has been found that health education is one of the best methods for health promotion, changing inappropriate personal behaviors, and increasing people's awareness and attitude through major health concerns, including the COVID-19 pandemic. This study aimed to investigate the effect of educational interventions with environmental health approach on the knowledge, attitude, and practice of people in the COVID-19 epidemic era in one residential complex in Tehran.   

This cross-sectional study was conducted in Tehran in 2021. The study population was households of a residential complex in Tehran, which was selected by a random sampling method. A researcher-made checklist was used to gather data for this study, and its validity and reliability in the domains of environmental health and knowledge, attitude, and practice in the COVID-19 setting were evaluated before it was used. An intervention was made through social media and the checklist was reevaluated after the intervention.  

A total number of 306 participants were enrolled in this study. In the assessment of the knowledge, attitude, and practice after the intervention, the mean score of the mentioned values increased significantly (P < 0.001). However, the influence of intervention was more prominent in the improvement of knowledge and attitude than practice.

Public health intervention with an environmental health approach can increase people's knowledge, attitude, and practice against chronic diseases and epidemics such as COVID-19.

Community participation has been accepted as a promising approach to promoting health and health equality. Based on Iran's constitution and the general health policies, community participation in health is addressed as a right, and during recent decades, some measures have been put in place. However, it is critical to improve public participation in Iran's health system and institutionalize community participation in health policymaking. This study aimed to identify barriers and facilities affecting public participation in Iran's health policymaking.  

Semi-structured qualitative interviews with health policymakers, health managers and planners, and other stakeholders were conducted to collect data. The conventional content analysis approach was used to analyze the data.  

Two themes—including community level and government level—and 10 categories were identified through the qualitative analysis.  Cultural and motivational factors, lack of awareness of the right to participate, and lack of sufficient knowledge and skills are among the identified barriers in the process of establishing effective interaction. From the health governance perspective, a lack of political will is identified as one of the obstacles.   

A culture of community involvement and political will are pivotal in the sustainability of community participation in health policymaking. The provision of a suitable context for participatory processes and capacity building on the community and government levels can be useful in institutionalizing community participation in the health system.

Despite the advances in the control of infectious diseases like cholera, they can potentially cause epidemics, especially in mass gathering events. One of the most important countries on the walking way of the Arbaeen religious event is Iran, which requires health system preparedness. The aim of this study was to predict the cholera epidemic in Iran by using the syndromic surveillance system of Iranian pilgrims in Iraq.  

The data of the Iranian pilgrims with acute watery diarrhea in Iraq during the Arbaeen religious event and the confirmed cholera cases of pilgrims after returning to Iran were analyzed. We used the Poisson regression model of the relationship between the numbers of cases to evaluate acute watery diarrhea and cholera. Spatial statistics and hot spot analysis were used to identify the provinces with the highest incidence. SPSS software Version 24 was used for statistical analysis.  

The frequency of acute watery diarrhea cases was 2232 and the frequency of cholera in pilgrims after returning to Iran was 641. The results of spatial analysis for acute watery diarrhea cases showed a high number of acute watery diarrhea cases in the Khuzestan and Isfahan provinces, located in hot spots. Using Poisson regression, the relationship between the number of acute watery diarrhea reported in the syndromic surveillance system and the number of cholera cases was confirmed.  

The syndromic surveillance system is useful to predict the outbreak of infectious diseases in large religious mass gatherings.

Individual variability in the length and thickness of hamstring tendon autografts is a serious drawback in using these tendons for anterior cruciate ligament reconstruction (ACLR). In this study, we aimed to determine the correlation between the anthropometric parameters and the size of hamstring tendon autografts.  

In a cross-sectional study, 52 male ACLR candidates were included. The length of semitendinosus and gracilis tendons and the diameter of single, doubled, and quadrupled tendons were measured. A graft sizing block device with an incremental size change of 0.5 mm (range 4.5-12) was used to measure the tendon graft diameter. The evaluated anthropometric parameters included age, gender, height, weight, BMI, thigh length and diameter, calf length, thigh-to-calf ratio, wrist diameter, and ankle diameter. A Pearson's or Spearman's correlation coefficient test was used for evaluating the correlation of anthropometric factors with graft characteristics.  

The mean age of the patients was 27.1 ± 6.4 years. The semitendinosus length was significantly correlated with the patient's height (r = 0.373, P = 0.007), thigh length (r = 0.364, P = 0.009), and calf length (r = 0.340, P = 0.015). The gracilis length was significantly correlated with thigh length (r = 0.278, P = 0.049). The mean quadruple diameter was 8.56 ± 1.15 mm (range 6.5-11). The quadruple diameter was ‎significantly correlated with the thigh length (r = 0.283, P = 0.044). No other significant correlation ‎was found between the tendons’ size and evaluated anthropometric parameters. 

Thigh length was correlated with the semitendinosus length, gracilis length, and quadruple diameter. Therefore, it could be regarded as the most consistent and promising anthropometric factor in the prediction of hamstring autograft size.

A variety of vaccinations have been developed to fight the coronavirus disease 2019 (Covid-19) 2 years after the coronavirus epidemic spread globally. During clinical studies, these vaccinations were linked to mild to severe side effects. This study aimed to evaluate the short-term side effects of Covid-19 vaccination in pregnant women in Zabol (Iran).  

This cross-sectional study was conducted between August and October 2021 to collect data on the adverse side effects of Covid-19 vaccinations among 117 pregnant women in Zabol (Iran). A questionnaire was used to collect demographic data, vaccination information, and vaccine complications. SPSS software Version 22 was used to analyze the data at 2 levels descriptive and inferential statistics.  

A total of 117 pregnant women aged 27.67 ± 5.14 years were included. After the first and second doses of Covid-19 vaccinations, 91 (86.7%) and 84 (71.8%) pregnant women, respectively, suffered adverse effects. Moreover, after the first dose, 55(51.4%) and 60 (56.1%) of pregnant women reported fatigue and headache, and after the second dose, 39 (33.3%) and 37 (31.6%) reported fatigue and headache, respectively.  

The side effects reported in our study after receiving Covid-19 vaccinations in pregnant women were similar to those described in clinical studies of vaccines and were mild to moderate, showing that injectable vaccines had safe profiles. More research is needed, however, to assess the long-term side effects of existing vaccines.

It seems that angled scissors may be able to minimize the occurrence of obstetric anal sphincter injuries (OASIS) during vaginal delivery by correcting the angle of the episiotomy incision.
For this purpose, this study aimed to evaluate the episiotomy characteristics of EPISCISSORS–60 scissors compared with Mayo scissors.  

In this single-blind clinical trial study, 64 pregnant women candidates for natural childbirth were included; 32 women underwent episiotomy with Mayo scissors and 32 underwent episiotomy with the EPISCISSORS–60 instrument. Then, post-suturing angle, incision length, episiotomy, postpartum pain, bleeding volume, and the incidence of OASIS and dyspareunia were assessed. The collected data were analyzed by independent sample t test, chi-square test, and the Fisher exact test.  

Episiotomy incision length in the EPISCISSORS–60 group with a mean of 4.75 ± 0.72 cm was significantly longer than the Mayo group with a mean of 3.91 ± 0.52cm (P < 0.001). In addition, the incidence of dyspareunia was not significantly different between the 2 groups (6.3% vs 15.6%; P = 0.426). Sphincter damage did not occur at all in the EPISCISSORS–60 group and only 2 cases of grade 3 sphincter rupture occurred in the Mayo group (P = 0.238). The mean of post suturing angle in the EPISCISSORS–60 group (59.09° ± 3.47°) was significantly higher than the Mayo group, with a mean of 31.06° ± 7.21° (P < 0.001).  

According to the results of the present study, the use of EPISCISSORS–60 can be associated with a higher post-suture episiotomy angle compared with Mayo scissors. As a result, both the incidence of OASIS and its long-term side effects, like dyspareunia, were decreased. However, in our study, the incidence of these complications was very rare and not different between the 2 groups.

No study has been conducted to specifically demonstrate the relationship between gestational diabetes mellitus (GDM) status, inflammatory factors, and postnatal umbilical coiling index (pUCI). Understanding this relationship could help select the best interventions to save the fetus. To evaluate the effects of maternal venous and umbilical cord blood levels of high sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-alpha) on pUCI in GDM and non-GDM groups.  

This prospective observational study included 40 participants in each of the GDM and non-GDM groups, matched for maternal age, ethnicity, and parity. The GDM diagnosis was confirmed by 24 to 28 weeks of gestation (WOG) and a 2-step strategy. The covariates of interest were maternal hs-CRP and TNF-α, measured at 37 to 40 WOG, and their UC analogous was measured during delivery. The gross morphologies were assessed immediately after delivery. The UC coiling was quantitatively assessed by the pUCI. To compare the GDM and non-GDM groups, the t test and the Mann-Whitney test were used for normal and non-normal variables, respectively.  

There was not a significant difference in hs-CRP and TNF-a levels in maternal venous blood or UC blood between the GDM and non-GDM groups. The mean (SD) of pUCI in the GDM and non-GDM groups were 0.28 (0.15) and 0.24 (0.21) (P = 0.441), respectively. In the GDM group, none of the 4 covariates of interest had significant effects on the UCI. Among the non-GDM participants, merely the UC hs-CRP had a direct association with the pUCI, with a Pearson correlation of 0.54 (P = 0.001). Impacts of hs-CRP and TNF-α on the pUCI were assessed using Poisson regression models and no significant findings were detected (95% CI, 0.999-1.001, for all parameters).  

In the GDM group, no apparent association was observed between inflammatory factors and pUCI, although a direct association was detected between UC hs-CRP and pUCI in the non-GDM.

Healthcare-associated infections (HAIs) are among the most critical challenges for patients and healthcare providers. To achieve the goals of the surveillance system, it is necessary to identify its barriers and problems. This study aimed to identify the barriers and problems of the surveillance system for HAIs.  

This qualitative study was conducted using the content analysis method to investigate the challenges of this surveillance system from the perspective of 18 infection control nurses from hospitals in different cities of Iran with work experience of 1 to 15 years. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method.  

In this study, we found 2 categories and 7 subcategories. Two categories were barriers related to human resources and organizational barriers to infection control. The 7 subcategories included weakness of medical staff in adherence to health principles, obstacles related to patients, high workload and insufficient motivation, lack of staff knowledge, lack of human resources, functional and logistical weaknesses, and weaknesses in the surveillance system.  

To reduce problems and improve HAIs reporting, the HAIs surveillance system needs the support of health system officials and managers. This administrative and support focus can establish the framework for removing and lowering other barriers, such as the number of reported cases, physician and staff noncooperation, and the prevalence of HAIs. It can also bring HAIs cases closer to reality.

According to previous research, hip internal rotation (HIR) aggravates low back pain (LBP) symptoms, especially in patients with lumbar flexion with rotation (F + R) syndrome. Therefore, the present study aimed to examine the lumbopelvic-hip rhythm during the HIR test in patients with this syndrome.  

In this cross-sectional study, 20 men without LBP and 20 matched men with LBP, subcategorized in the F+R subgroup, participated. The participants performed the HIR test. Kinematics data were recorded using a motion analysis system. After processing the kinematics, a comparison was made in the hip and pelvic kinematics between the groups.  

A statistical analysis based on an independent t test revealed a significant increased (P < 0.05) pelvic rotation during the tests with the dominant (P = 0.007) and nondominant limbs (P = 0.025) in those with LBP. The analysis also showed that during the test with the dominant lower limb, the pelvis and hip moved with a more synchronized pattern in patients with LBP (P = 0.001).  

In the patients with lumbar F + R syndrome, there was a tendency for early pelvic rotation during the dominant HIR test. Moreover, LBP people also exhibited a greater pelvic rotation range of motion in the first half and whole pathways of the test. These impairments could be a risk factor for the development of LBP symptoms in these patients.

There is still no standard of care to manage thoracolumbar burst fractures. With all the recent advances, posterior approaches are still one of the mainstays of treatment. On the other hand, while spinal canal decompression in neurological impaired patients is an important goal of treatment, its technique remains controversial.
This study compared the effects of direct laminectomy decompression against ligamentotaxis/indirect canal decompression on neurological and radiographic improvements.  

A prospective double-blind randomized clinical trial was conducted on 60 thoracolumbar burst-fracture patients meeting our inclusion and exclusion criteria. They were randomized into 2 treatment arms: (1) direct decompression using laminectomy and (2) indirect decompression using ligamentotaxis/distraction. Each patient was observed for 6 months, and their neurological and radiographical data were collected prospectively. Statistical analysis was done by the Student t test, Friedman test, Mann Whitney-U test, Wilcoxon ranked test, and 1-way analysis of variance.  

Among 60 patients enrolled in our study, each treatment arm had an improvement in Frankel scores but there was no difference between the groups at any given time. After 6 months of surgery, local sagittal kyphosis improved in both groups (from 32.2 to 7.43 and 29.93 to 8.77 for the indirect and direct groups, respectively), as well as anterior vertebral height ratio (from 57.73 to 70.7 and 62.17 to 66.27 for the indirect and direct group, respectively) and posterior vertebral height ratio (from 61.17 to 74.87 and 64 to 67.5 for the indirect and direct group, respectively). For between-group comparisons after 6 months, there was a significant difference only for posterior vertebral height ratio (P = 0.040).  

Posterior approaches with ligamentotaxis have shown to be safe and may present the same outcome as direct decompression techniques using wide laminectomy.

Anterior dislocation is the most common type of shoulder dislocation, and even after appropriate treatment, recurrence after a primary traumatic anterior dislocation is highly frequent. Surgical options for treating recurrent anterior dislocations mainly include Bankart arthroscopic and Latarjet open surgery. We aimed to evaluate the outcomes and complication rates of the open Latarjet procedure in a series of patients with recurrent anterior shoulder dislocation.  

A total of 55 patients with recurrent anterior shoulder dislocation who underwent an open Latarjet procedure were included in this retrospective cohort study. Shoulder range of motion and postoperative complications, including neurapraxia, re-dislocation, hematoma, infection, dehiscence, implant failure, and pain, were evaluated.  

The mean age of the patients was 27.7 ± 6.5 ‎years‎.‎‏ The mean time interval after the first ‏dislocation was ‏‎3.4 ± 2.7 ‎years‎. ‎The mean preoperative and postoperative ‏forward flexion (P = 0.200), ‎abduction (P = 0.200), external rotation (P = 0.066), and internal rotation (P = 0.310) were not significantly different. Postoperative complications included 1 case of postoperative musculocutaneous ‎nerve ‎neurapraxia, 1 case of re-‎dislocation, 1 case of wound dehiscence, and 2 cases of screw breakage. Postoperative pain ‎was also recorded in 11 (20%) patients that were either in the form of occasional night pain (n = 6) or activity-dependent pain (n = 5).‎  

Open Latarjet procedure is an efficient procedure for the treatment of recurrent anterior shoulder dislocation. However, its rate of complications remains relatively high, and surgeons must consider this drawback in their decision-making and address patients' expectations.

The effect of spinopelvic alignment on low back pain (LBP) incidence has been studied in many investigations. However, the interrelation between spinopelvic parameters and LBP is poorly understood. In particular, it is unknown whether particular patterns of spinopelvic parameters render nonspecific LBP. In this study, we aimed to evaluate the role of spinopelvic parameters as risk factors of nonspecific LBP.  

In this case-control study, spinopelvic parameters, including lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI), were compared between 148 patients with nonspecific LBP and 148 healthy controls. Demographic characteristics of the patients, such as age, gender, occupation, smoking, diabetes mellitus, and body mass index (BMI), were recorded as confounders. Spinopelvic parameters were assessed using radiographic findings in 2 groups. The analysis was done once as univariate (Kolmogorov-Smirnov test) and once as multivariate (multivariate logistic regression) analysis.  

Univariate analysis showed that female gender, higher BMI, smoking, and blue-collar jobs were associated with a higher risk of nonspecific LBP. LL, SS, and PI, but not PT, were all greater in LPB patients in the univariate analysis regarding the spinopelvic parameters. Multivariate analysis showed female gender (odds ratio adjusted (ORAdj) = 4.26 [95% CI, 2.11-9.58]; P = 0.001) and LL (ORAdj = 1.58; [95% CI, 1.18-3.22]; P = 0.026) were predictable risk factors for Nonspecific LBP.  

Spinopelvic parameters, particularly LL, could be considered as risk factors of nonspecific LBP so that a more significant LL might indicate a greater risk of LBP. However, the role of other parameters in this association could not be neglected.

A rather common side effect of using prosthetic grafts is infection of the groin area. Infections in the groin may be avoided by performing arterial bypass  tenneling via the obturator foramen during lower extremity revascularization. This study aimed to evaluate the safety and efficacy of extra-anatomical bypass obturator in patients with groin infection.  

This cohort included a convenient sample of 100 patients with groin infections who planned to do an extra-anatomical obturator bypass. All patients were subjected to history taking and clinical assessment. Ultrasonography with duplex screening is a good initial technique to assess groin masses. Combination of computed tomography (CT) or magnetic resonance imaging (MRI) with indium-labeled leucocyte scintigraphy can also play a role in the diagnosis.  

Inflow from the already-existing graft limb was used in 54% of obturator canal bypass (OCB) procedures, with 32 limbs coming from the main iliac (27.3%) and 6 limbs from the infrarenal aorta (5.1%). The distal superficial femoral artery was used in 21 limbs (17.9%), while the above-knee popliteal artery was selected as the outflow artery in 82% of cases. Primary aided patency was 68% at 24 months, according to Kaplan-Meier analysis, whereas primary patency was 63% at that time. At 24 months, the secondary patency of the OCB was 83%.  

In case of groin infections, an excellent option to restore flow is an obturator bypass graft. This graft is strong, reliable, and safe. As a result of its high patency rate, it may be the first choice in certain circumstances.

NSAID-exacerbated respiratory disease (N-ERD) is a highly heterogeneous disorder with various clinical symptoms. The aspirin challenge test is a gold standard method for its diagnosis, and there are still no reliable in vitro diagnostic biomarkers yet. Oral challenge tests are time-consuming and may be associated with a risk of severe systemic reactions. This study aimed to evaluate whether patients with poor responses to medical management are more susceptible to being aspirin-sensitive.  

In this cohort study, after CT scanning of all patients and subject selection, conventional medical treatment was started as follows and continued for three consecutive months: at first, saline nose wash twice per day, intranasal beclomethasone spray one puff in each nostril twice per day, montelukast 10 mg tablet once daily, a ten-day course of oral prednisolone starting with the dose of 25 mg per day and taper and discontinued thereafter. Sinonasal outcome test 22 (SNOT22) was used for the evaluation of symptom severity. Statistical analyses were performed with SPSS version 23, and data were analyzed using an independent samples T-test, paired T-test, and Receiver operating curve analysis  

25 males and 53 females were enrolled in this study, with an average age of 41.56 ± 11.74 years old (18-36). Aspirin challenge test results were positive in 29 (37.2%) patients. The average SNOT22 scores before the treatment were 52.97 ± 17.73 and 47.04 ± 18.30 in aspirin-sensitive and aspirin-tolerant patients, respectively, and decreased to 27.41 ± 16.61 and 24.88 ± 16.72 in aspirin-sensitive and aspirin-tolerant patients after the treatment, respectively. There was no significant difference in SNOT22 scores between the groups.  

The severity of symptoms before treatment and clinical improvement after treatment are not good predictors of N-ERD.

Environmental exposures and genetic predisposition interactions may result in autoimmune rheumatic diseases. This study aimed to determine the effect of outdoor air pollutants on the activity of rheumatoid arthritis (RA) in a longitudinal follow-up.  

We longitudinally studied 50 patients with RA bimonthly over 6 months in Mashhad, one of the most polluted cities in Iran. Disease activity and health-related quality of life (HRQoL) were examined according to the disease activity score (DAS28ESR), health assessment questionnaires (HAQ), physical health component summary (PCS), and visual analogue scale (VAS) criteria. The outdoor air pollutant was measured by monitoring the average concentration of nitrogen oxide (NO), carbon monoxide (CO), O2 level, Sulfur dioxide (SO2), and some particles less than 10 and 2.5 micrometers in diameter (PM <10 µm, PM <2.5 µm). The temperature and humidity levels were also measured. The univariate and multivariate statistical analyses were used for data analysis and the role of confounding factors was determined using the generalized estimation equation method.  

Statistical analysis indicated a significant increase of the DAS28ESR (B = 0.04 [0.08]; P = 0.01) and VAS (B = 4.48 [1.73]; P = 0.01) by CO concentration. Moreover, a number of polluted days increased the VAS in patients. In addition, other air pollutants, temperature, and humidity were not affected significantly by the DAS28ESR and quality of life indexes by considering confounders such as medications, age, and job.  

Based on our findings, CO concentration was the only effective outdoor air pollutant that could increase RA disease activity. In addition, CO concentration and the number of polluted days make patients feel more ill. As the role of indoor air pollutants is highly important, further research on this critical topic is required to establish the role of air pollution on RA disease activity.

Providing optimal rehabilitation services for people with disabilities has always been recognized as a major concern of health systems in all countries. Stewardship is one of the biggest challenges to provide rehabilitation services to people with disabilities in Iran. We advocate the Ministry of Health & Medical Education (MoHME) to take the lead as a steward of rehabilitation services in Iran, while the dedicated sections in the MoHME need to be determined, with a clear list of responsibilities and affiliations.

Coronavirus disease 2019 (COVID-19) viral load determined from the cycle threshold (CT) values may be a marker of disease severity and predict disease progression. Our study aimed to investigate the relationship between SARS-CoV-19 cycle thresholds or viral load, laboratory markers, and patient prognosis.
  

Patients who were admitted to Imam Reza Hospital at Mashhad University of Medical Sciences between March 2020 and March 2021 and had COVID-19 polymerase chain reaction (PCR)-confirmed at random were included in this cross-sectional study. Patients were randomly selected from those who tested positive on nasopharyngeal and oropharyngeal reverse transcription-PCR samples. The inclusion criteria were all patients older than 16 years with positive COVID-19 PCR results. Samples with Ct values of ≤36 were considered positive for SARS-CoV-2 RNA. Patients who did not have laboratory markers were excluded. We used SPSS Version 16 (Pearson correlation, analysis of variance, and logistic regression tests) to analyze the data. A P ≤ 0.05 was considered statistically significant.
  

In our study, serum lactate dehydrogenase and aspartate aminotransferase were found to be laboratory biomarkers inversely correlated with COVID-19 Ct values, indicating higher viral load (r = -0.14; P = 0.024 and r = -0.12; P = 0.053, respectively). Also, the platelet count is lower in patients with higher viral loads (r = 0.18;  P < 0.001). However, we found no correlation between the viral load and some laboratory biomarkers such as ferritin, white blood cell and lymphocyte count, alanine transaminase, and c-reactive protein (P > 0.05). The patient’s length of hospital stay was not correlated with their viral load (P > 0.05).
  

The COVID-19 viral load has been linked to some laboratory indicators and may be used to predict patient death. These discoveries might help in the treatment of COVID-19 disease.

Acute myeloid leukemia (AML) is the most common acute leukemia in adults and accompanies a worse survival.  In this study, gene expression levels of 5 key players of apoptosis, including DR4, DR5, FAS, caspase 8, and DNA damage-induced apoptosis suppressor (DDIAS), have been evaluated in AML patients compared with controls, aiming to evaluate their possible role and prognostic impact.  

This cross-sectional study was performed in the Cancer Molecular Pathology Research Center, Mashhad University of Medical Sciences. A total of 30 newly diagnosed AML cases as well as 30 healthy controls enrolled in the study. Real-time polymerase chain reaction was used to evaluate the expressions of DR4, DR5, FAS, DDIAS, and caspase 8 genes in cases and controls. Other necessary data, including cytogenetic findings, mutations, French-American-British (FAB) classification, and survival, were retrieved from hospital records and by direct contact with patients. Statistical analysis was done by SPSS software. When appropriate, the Mann-Whitney U, Pearson's correlation, and the t tests were utilized. Overall survival (OS) was estimated using the Kaplan-Meier method.  

The expression of all evaluated genes, including DDIAS (0.89 ± 0.20), DR4 (0.67 ± 0.24), DR5 (0.72 ± 0.24), FAS (0.70 ± 0.25), and Caspase 8 (0.77 ± 0.20) were significantly decreased in AML patients compared with the controls (P < 0.001). Patients with the t (16;16) or inv (16) expressed significantly higher amounts of the FAS gene and those with FLT3 mutation exhibited lower expression of caspase 8. Expression of the evaluated genes showed no significant effect on survival.  

The expression of DR4, DR5, FAS, and caspase 8 seems to be decreased in AML. Lower expression of these molecules may aid AML cells in avoiding apoptosis because they are involved in the initiation of apoptosis, making them potential targets for treatment.

A positive family history (FH) of coronary artery disease (CAD) is considered an independent risk factor for developing CAD. However, the relationship between the occurrence, angiographic anatomical location of the stenosis, and extent of CAD and the risk factors in the patients and their relatives is not well defined. Evaluation of this relationship is our main goal in this study.   

In this descriptive cross-sectional study, the FH data for CAD and premature death in first-and second-degree relatives, angiographic anatomical location of the stenosis, the extent of CAD in the patients and their relatives, as well as the relationship between other risk factors and the extent of CAD, were collected from 300 adult patients undergoing coronary angiography at Farshchian cardiovascular hospital in Hamadan (Iran) between March 2020 and 2021. SPSS 24 and the chi-square, Fisher exact, and student t tests were used to analyze data. The significance level was considered P < 0.05.  

Out of 300 patients, 185 (61.7%) were men and 115 (38.3%) were women. A total of 177 patients (59%) in maternal and 82 patients (27.3%) in paternal relatives had an FH of CAD. There was a significant relationship between the severity of coronary artery involvement and risk factors (P < 0.001). Moreover, there was no significant relationship between the location of coronary artery involvement of the right coronary artery, left coronary artery, and left anterior descending artery and the severity of involvement of patients undergoing coronary angiography and their first- and second-degree relatives (P = 0.480).  

Our findings suggest that there was no significant relationship between the anatomical location of the stenosis and the number of vessels involved and the FH of the patients. In patients with an FH, the extent of CAD significantly increased according to their risk factors for heart disease.

The quality of the wound healing at the donor site significantly determines the overall condition of the burn patient, the extent of wound fluid and protein losses, the severity of any systemic in-flammatory reaction, and the intensity of the pain syndrome. It is known that the stromal vas-cular fraction (SVF)  has a beneficial effect on the healing of wound defects. This study is aimed at assessing the safety and effectiveness of the application of the SVF of autologous adipose tis-sue to stimulate wound healing of the donor site in patients with burns.  

This placebo-controlled clinical study included 38 patients with third-degree thermal skin burns. The patients underwent liposuction, enzymatic isolation of the SVF, and intradermal injection of the preparation into the wounds in the donor site, followed by tewametry, cutome-try, thermography and biopsy after 12 days. Quantitative indicators were compared using the Mann-Whitney test for unrelated groups and the Wilcoxon test for related groups. Spearman's rank correlation coefficient (RS) was used to assess the correlation  

Epithelization of the wounds in all patients was seen over an average area of 88 (84;92) %, there being no significant differences between the actual and the control wound sites for this parameter. Transdermal water loss in the test wound sites was 2 times lower than in the control sites (P = 0.001). The wound donor sites regained their temperature distribution faster than the control sites (P = 0.042). Histological preparations of the skin of the wound sites revealed that their epidermal layer was 19% thicker compared to the controls (P = 0.043). It should be noted that five adverse events related to manipulations in the postoperative period were registered.

Transplantation of SVF autologous adipose tissue into the wound area in most clinical cases proceeded without complications. The area of epithelialization of wound areas af-ter the introduction of SVF did not change, although a significant decrease in transdermal water loss was observed in the wound areas with an improvement in their thermoregulation and an increase in the thickness of the epidermis.

Swine flu (H1N1) and Coronavirus diseases (COVID-19) have been compared in the past few months. Both pandemics sparked a worldwide major panic. Although both have some common symptoms and diagnoses, they are quite different in many aspects. The current study aimed to investigate the differences in clinical and viral behaviors between H1N1 Influenza and COVID-19 pneumonia.  

This was a retrospective study of adult patients hospitalized with H1N1 influenza pneumonia between January 2019 and February 2020, and patients hospitalized with COVID-19 during the outbreak.  A demographic and clinical characteristic of H1N1 influenza and COVID-19 patients were recorded. Both groups were compared—using an independent samples student t test for continuous variables and a chi-square test for categorical data—to identify significantly different parameters between the 2 diseases.  

A total of 78 patients were included and divided into 2 groups: 33 patients (42.3%) with H1N1 and 45 patients (57.7%) with COVID-19. The mean age of the patients was 43.3 ± 10.6 years. Bronchial asthma was significantly higher among patients with H1N1, while diabetes mellitus was significantly higher among patients with COVID-19. Right lower lobe affection was significantly present among those with H1N1 than those with COVID (100% vs 0%). The monocytic count was significantly higher among those with H1N1 than COVID-19 (11.63 ± 1.50 vs 7.76 ± 1.68; P < 0.001). Respiratory rates of more than 22 c/min significantly increased in patients with HINI than in those with COVID-19 (18.2% vs 4.4%; P = 0.05). Mortality increased in patients with HINI than in those with COVID-19 (18.2% vs 6.7%). However, the difference did not reach statistical significance (P = 0.15).  

Clinically, it is difficult to distinguish between H1N1 and COVID-19. Thus, a polymerase chain reaction is recommended for all patients suffering from influenza-like symptoms to rule out influenza A subtype H1N1 and/or SARS-CoV2.

Pregnant women infected with the coronavirus disease 2019 (COVID-19) are at risk for adverse pregnancy outcomes, and the only real preventive strategy against COVID-19 is mass vaccination. This study aimed to examine the effectiveness, immunogenicity, and safety of Covid-19 vaccination in pregnant women.  

  A combination of search terms was performed by 2 researchers independently in the Web of Science, PubMed, and Scopus databases, the World Health Organization website, and the US Centers for Disease Control (CDC) website up to February 2022. After the selection of eligible studies, the review process, description, and summarization of the selected studies were performed by the research team.  

Finally, 22 articles were included in this study. Evidence supports the safety of COVID-19 vaccination during pregnancy. There is no risk of transmitting COVID-19 to infants during lactation. In addition, antibodies made by vaccination can protect infants through breast milk.  

The scientific community believes that being vaccinated as soon as possible is the best course of action because there is no evidence to suggest that the COVID-19 vaccine poses a risk to expectant or nursing women.

One of the most important indicators of the quality of education and academic achievement is students' academic engagement, and the progress of using online education has fundamentally changed the learning-teaching processes Therefore, the aim of this study was to compare the effect of two methods of online education based on Sweller's cognitive load theory and online education in a conventional method on the academic engagement of medical students in anatomy.  

The present study was a quasi-experimental study with two groups not identical to the before and after design. To collect information, the Shuffle and Becker academic engagement questionnaire with Cronbach's alpha of 0.85 was used. The subject was 104 basic science students. General medicine students were divided by non-random method into two groups of intervention (n = 52) and control (n = 52). After the intervention, a post-test was taken. After collecting data, this data was entered into SPSS software version 24.  

The results of the independent t-test showed that there is a statistically significant difference between the mean scores of academic engagement in the control and intervention groups after the intervention and also, the results of the dependent t-test showed that online teaching of anatomy course based on Sweller's cognitive load theory has a positive and significant effect on medical students' academic engagement.  

Considering the results of this study and the significant effect of online education based on cognitive theory, it is suggested that teachers and educators be educated about the basic principles of load cognitive theory so that they can apply these principles due to the limited capacity of active memory.

Many people are exposed to cigarette smoke actively or passively. We aimed to determine the effect of active and passive smoking on hearing thresholds and hearing loss noise-exposed workers.

This cross-sectional study was conducted on 929 metal workers. We divided the workers into 3 groups according to smoking status—current smokers, nonsmokers, and passive smokers. Audiometric testing was recorded for both ears. Hearing loss was defined by 3 models. The SPSS software Version 24 was used to analyze the collected data. We used an independent t test, chi-square, Fisher exact, and analysis of variance tests and logistic regression, and the significance level was set at P ˂0.05 to interpret the relationships between variables.

The hearing threshold levels at 4000 Hz, high frequencies, and low frequencies were significantly higher in smokers than nonsmokers (P < 0.05). Also, and hearing loss at the 4000 Hz (P = 0.002; odds ratio [OR] = 1.96; 95% CI = 1.27-3.03) and high frequencies (P = 0.001; OR = 2.15; 95% CI = 1.36-3.4) had a significant correlation with smoking. Hearing loss was significantly correlated with passive smoking at 4000 Hz (P < 0.001; OR = 5.87; 95% CI = 3.29-10.47), high frequencies (P < 0.001; OR = 7.16; 95% CI = 3.97-12.89) and low frequencies (P = 0.021; OR = 4.16; 95% CI = 1.12-15.43).

The findings show that active and passive smokers who work in noisy environments are at higher risk for noise-induced hearing loss. Therefore, smoking cessation in smoker workers and reduction of environmental exposure to cigarette smoke is necessary to reduce the exacerbation of hearing loss. Moreover, more attention should be paid to passive smokers and they should be given priority in the same programs.

There are considerable documents suggesting that inadequate fiber intake (FI) is a key   risk factor for various chronic diseases. The aim of this study was to investigate   Dietary FI in the Persian elderly.  

This descriptive-analytic study was performed to investigate FI in a  sample of the elderly who received  free  services from healthcare centers in Karaj, Iran. For sampling method at first, the names of 36 centers were written on small pieces of paper and poured into a container, then another person was asked to randomly select the names of 10 centers, then referring to each of the centers and preparing a list of elderly people, the study subjects were selected, The study was conducted between September 2018, and April 2019Several questionnaires were used to collect data regarding DF: characteristics, daily  FI , knowledge, SE (self-efficacy), perceived benefits, and barriers towards FI as well as stage of readiness of FI. t-test and ANOVA were used to compare independent mean values. Data were checked for normality before analysis by using Kolmogorov-Smirnov (K-S) test to check data normality.  

Totally of 400 elderly individuals entered the study with the average amount of fiber per day. The data analysis indicated they did not know the recommended intake of at least 25 gr each day. feeling less hungry and fiber’s price was the most frequent perceived benefits and barriers towards FI , respectively. Gastrointestinal diseases (P < 0.001), smoking (P < 0.001), and perceived barriers (P < 0.001), were statistically significant independent positive predictors of FI.  

The findings of the current study indicated that FI among elderly people in Iran was very low and varied a great  by gender, education, marital status, income level, employment status, smoking, stage of change, and gastrointestinal disease.

Amyotrophic Lateral Sclerosis (ALS) is a rare disease that can bring different emotional, physical, and psychological burdens. This study aimed to investigate the quality of life in patients with ALS.  

This is a cross-sectional study. Fifty-two patients contributed in this study. The setting was an ALS clinic in Iran. A mixed method was used in this study. We applied a short form of the WHO Quality of Life questionnaire (WHOQOL) to measure the quality of life of patients. Also, all participants were interviewed through the semi-structured interview guide. To measure physical strength and functioning the Appel ALS Rating Scale (AALS) was employed in this study. To analyze the data, a two-tailed t-test and x2 test were used.  

42.3% of the participants were female. The age of the participants ranged between 28 to 81 (mean=57.6). The disease duration ranged from 0.07 to 14 years (mean=1.8). The overall mean QOL was 58.7 (±8.1). The overall mean of the AALS score was 74.4 (±24.2). The results of the qualitative part of the study showed four psychosocial themes: (1) internal personality traits, communicating with friends and family; (2) religion and spirituality; (3) stress, mood changes, and difficult relationship; and (4) changes in lifestyle, work, leisure time and financial situation.  

Despite recent advances, ALS is still one of the diseases for which there is no effective treatment. Paying attention to psychosocial issues in patients with ALS can play a very important role in increasing the quality of life of patients.

Dentures, both partial and complete, have been shown to have the same impact on one's quality of life. Due to the impossibility of randomization in these studies, they are prone to selection bias.  This study aimed to compare the effect of partial and complete dentures on oral health-related quality of life (OHRQoL) by propensity score to overcome selection bias.  

This is a cross-sectional descriptive-analytic study. A total of 1376 people participated in this study. Age, sex, marital status, education level, smoking, smoking opium and its derivatives, and dental visit was collected by a checklist. OHRQoL was measured by the OHIP-14 questionnaire. The generalized boosted model was used to estimate the propensity score. Missing data were imputed using multiple imputations with mixed models. The assumptions of multivariable regression analysis and propensity score method were first examined, and then the quality of life related to oral health was compared between the two groups.  

The regression model's assumptions were not verified due to high skewness and collinearity. The results of the normality test (P < 0.001) and goodness fit test (P < 0.001) revealed that the regression model did not fit the data. The propensity score method reduced at least 76% of the bias resulting from the distribution difference between the confounding variables and was used for analysis. In the regression and propensity score method, the results showed that the total OHIP-14 score of the complete prosthesis group was higher than the partial prosthesis group at 3.92 (95% CI = (2.18,5.65)) and 3.64 (95% CI = (1.93,4.53)), respectively. This difference was clinically and statistically significant (P < 0.001). In addition, there is a significant difference in the two groups based on propensity in all seven areas (P < 0.001). But there is no significant difference in the regression adjustment of the Functional limitation of the two groups (P = 0.035).  

The propensity score has fewer assumptions than the regression method and may be more reliable for OHIP scores. The propensity score analysis revealed that despite the costs and repair issues associated with partial dentures, complete denture wearers have lower OHRQoL than partial denture wearers.

The instructor is one of the key factors in attaining educational goals in medical education, and the instructor’s competencies facilitate students’ educational achievement. The present study is an attempt to explain the experiences of faculty members and students of characteristics of competent professors who play an influential role in the academic achievement of basic medical sciences students in universities of medical sciences across the country.  

The present study is a conventional qualitative content analysis. Fifteen faculty members and students of medicine from Iranian universities of medical sciences from different regions of the country were selected using a purposive and then theoretical sampling. A semi-structured interview was used for data collection.  

In this study, four themes and nine sub-themes were extracted from interviews. The themes included “clinical knowledge”, “teaching competency”, “monitoring students’ performance”, and “cognitive-psychological arousal”. The sub-themes were “clinical knowledge’ including “Non-applied teaching of basic sciences and unfamiliarity of instructors of basic sciences with the clinic”;  “teaching competency” including “having instructional design skills, teaching based on the psychology of learning, and professional development”; “monitoring students’ performance” including “fair evaluation and valid evaluation”, and “cognitive-psychological arousal” including “student support and reinforcement”.  

The present study identified the important characteristics of the competencies of professors of basic medical sciences working in Iranian medical universities. The competency of professors is essential in promoting students’ educational achievement and training efficient and professional students in the field of medicine to render quality health services. The results of this study will assist administrators and educational policymakers in planning for the promotion of professors and medical education.

Medical errors cause disability and mortality in intensive care units (ICUs). We aimed to determine the occurrence and causes of medical errors in the ICUs of Iran.  

In this cross-sectional study, data from the family complaint files referred to The disciplinary authority of Iran Medical Council was retrospectively reviewed to explore the causes of medical errors. Statistical analysis was performed in SPSS Version 26.0.  

A total of 293 complaint files were referred to the disciplinary commission from 2014 to 2019, of which 95 files were related to medical errors in ICUs. The median age of patients was 62 years (46-74 years) and 52 (54.7%) patients were men. Also, 37 (38.9%) patients had decreased levels of consciousness and 42 (42.2%) patients had cardiovascular disease. A total of 40 (42.1%) patients experienced a single medical error and 55 (57.9%) patients experienced more than 1. Causes of medical errors in patients were physician's or nurse’s negligence in 53 (55.8%) patients, weak interaction of physician and nurse with the patient and family members in 11 (11.6%) patients, weak interprofessional interaction among physicians in 7 (7.4%) patients, equipment and structure of ICUs in 7 (7.4 patients, nature of ICUs and patients in 6 (6.3%) patients, weak physician-nurse interprofessional interaction in 5 (5.2%) patients) patients, low attention of the physician and the nurse to medication safety in 6 (6.3%) patients.  

  Patient safety is impacted by a variety of medical mistakes. Interprofessional strategies can be developed and put into action to mitigate medical errors in ICUs.

Efficient and effective management of budgets and financial resources is critical for health systems to achieve their goals; in this regard, countries may face budgetary and financial challenges owing to the weak prediction of resources and consumptions, and lack of prioritization for their budget. This study aims to identify the most critical policies and events that have affected public financial management and health budgeting and existing challenges in Iran.  

We conducted the present study in 2022 using a 2-stage qualitative method. First, by reviewing upstream documents and laws, we identified evidence related to health budgeting. Then, we conducted 13 semi-structured interviews with informed people in the health budgeting field that led us toward the main challenges through thematic content analysis.  

After reviewing 48 upstream documents related to health budgeting, we identified 85 policies. After reviewing the articles, we achieved 11 themes and 71 subthemes. The most critical challenges of the budgeting cycle were as follows: (I) budget formulation, including inappropriate budget structure, conflicts of interest and infringement, lack of financial sustainability, and transparency; (II) budget execution, including a nonexecutable approved budget, complicated allocation process, and ineffective allocations; and (III) monitoring, reporting, and evaluation (MR&E), including fragmentation of MR&E processes, ineffective monitoring and evaluation, weak evaluation of platforms, and inadequate transparency.  

Most challenges in the health budgeting system are related to the budget formulation and approval stage that have their roots in implementation, monitoring, and reporting. In addition, Iran's macroeconomic and financial issues have also damaged the budgeting of the health sector. Budget problems affect the goals and outcomes of this sector, especially the health system.

The present study aimed to compare the effects of simultaneous cognitive and motor tasks on walking performance between individuals with nonspecific chronic low back pain (NSCLBP) and healthy controls.  

A total of 20 patients with NSCLBP and 20 healthy controls participated in this study. They walked at their self-selected speed on a treadmill under 3 walking conditions in a randomized order: walking only, walking while performing a concurrent cognitive task, and walking while performing a concurrent motor task. Two-way repeated measure analysis of variance with additional post hoc comparison (Bonferroni test) was used to evaluate the effects of group and walking conditions on gait parameters.   

The result showed a significant main effect of the group for swing time (P = 0.012) and double support time (P = 0.021) in those with NSCLBP compared with healthy controls. Moreover, there was a significant interaction between the group and condition for cadence (P = 0.004) and step width variability (P = 0.016). Regarding stride length variability and stride time variability, the analysis indicated a significant effect of condition (P = 0.002 and P = 0.030, respectively). In both groups, no significant differences were observed in gait parameters between motor dual task and single walking (P > 0.05).  

Our findings indicated that those with NSCLBP adapted successfully to walking performance to maintain the performance of the concurrent cognitive task under the cognitive dual-task walking condition. Moreover, the present study observed no dual-task interference under the motor dual-task condition.

Pregnant women who have gestational diabetes mellitus (GDM) are more prone to adverse pregnancy outcomes. We estimated the prevalence of GDM in Iran.  

Web of Science, Scopus, PubMed, Google Scholar, and Persian databases (SID, Magiran, Irandoc, and) were searched using the MeSH and non-MeSH terms in abstract, title, or keywords of articles until June 2021, with no limitation in time. Random effects models were applied to summarize the GDM prevalence in Iran. The obtained data were quantitatively analyzed to determine an effect size for each paper. The pooled effect size was introduced as prevalence and 95% confidence interval. Sensitivity analyses and subgroup analyses were done to determine heterogeneity. Publication bias was assessed by the classic fail-safe N and Egger test.  

A total of 53 papers were considered for meta‐analysis, involving 56,521 Iranians. The total GDM prevalence in Iran was 7.6% (95% CI, 6.1%–9.4%).  

This meta-analysis was the newest to estimate the GDM prevalence among Iranian women. Our results suggest a high prevalence of GDM in Iran, showing that Iran might have many GDM patients.

In human and animal studies, ankylosing spondylitis (AS) has been increasingly linked to changes in the microbial inhabitants in the human body (microbiome). These studies have primarily now concentrated on the microbial communities that live in the gastrointestinal tract. However, evidence suggests that various molecular techniques can be used to detect microbial DNA in blood circulation. This DNA might be an unknown reservoir of biomarkers with the potential to track alterations in the microbiomes of remote locations, such as the gut. To this end, we compared the presence and identity of microbial DNA in blood samples taken from ankylosing spondylitis patients to healthy control subjects by amplifying and sequencing the bacterial 16S rRNA variable region four.  

The study's design is a case study based on the presence and identity of bacterial DNA in the blood of Ankylosing spondylitis (AS) patients (n = 10) and healthy control subjects (n = 10)  was investigated by amplifying and sequencing the bacterial 16S rRNA gene. Blood concentrations of the cytokines TNF alpha, IL-17A, and IL-23 were determined by the Human Magnetic Luminex Screening, and data were analysed using an Unpaired T-test.  

Using PCR amplification, 8 of 10 AS patients (80%) and 8 of 10 healthy control samples (80%) had microbial 16S rRNA in their blood. At the phylum level, Proteobacteria (Control = 48.5%, AS = 52%), Firmicutes (Control = 27.8%, AS = 26.1%), Actinobacteria (Control = 15.4%, AS = 10.7%), and Bacteroidetes (Control = 6.5%, AS = 10%) dominated the blood microbiome. A two-tailed Mann-Whitney test found that Ankylosing Spondylitis was associated with significantly elevated Bacteroides (P < 0.05), Prevotella (P < 0.001), and Micrococcus (P < 0.01), and significantly reduced levels of Corynebacterium 1 (P < 0.001), Gemella (P < 0.01), and Alloprevotella (P < 0.05), compared to healthy controls. Additionally, it was shown that the presence of the Prevotella genus was highly positively correlated with higher levels of TNF-alpha (P < 0.05; r = 0.8) in AS patients' blood.

This article reveals that a blood microbiome exists in healthy individuals and identifies particular taxa modulated in disease. These blood-derived signatures indicate that this field needs more research and may be helpful as disease biomarkers.

Acute cerebrovascular accident is known to be one of the main causes of morbidity, mortality, long-term disability, and disability in society.
To investigate the quality of life of patients who have suffered from acute cerebrovascular accident (hereinafter ACVA) in stratified groups by age, gender, diagnosis, type (primary or secondary), and severity of a stroke, as well as undergoing rehabilitation.  

This research is a cross-sectional descriptive-analytical study. The main research method is a survey. Data collection was carried out in 2020 in Almaty of the Republic of Kazakhstan by inpatient doctors (City Clinical Hospital No. 5 of the Public Health Department of Almaty), engaged in the rehabilitation treatment of patients with acute cerebrovascular accident. The standardized questionnaire EQ-5D-5L was used to assess the quality of life due to health conditions. Data on the state of "mobility", "self-care", "daily activities", "pain", "anxiety", as well as data on self-assessment of health status (according to the EQ VAS scale) were analyzed using the Level Sum Scores (hereinafter LSS).  

The study involved 258 respondents who had a stroke. The survey was conducted 2 months after the respondents were discharged from the hospital. The average LSS index of patients who underwent ACVA was 10.2 (9.7±10.7). Significant differences in LSS levels (P ≤ 0.001) were revealed by the severity of stroke and by the fact of rehabilitation. Differences in LSS levels by age, gender, diagnosis, and type of ACVA are insignificant (P > 0.05).
The difference in health indicators of patients with primary and repeated strokes indicates the fact of deterioration in the quality of life with each subsequent stroke. The quality of life of patients with ACVA is associated with the fact of rehabilitation: low values of EQ VAS in the group of patients who did not undergo rehabilitation and high values of EQ VAS in those who underwent rehabilitation.  

After a stroke, the majority of patients tend to have a negative quality of life, mostly due to violations of the component "daily activities". The identified significant disparities in LSS and EQ VAS indicators further show that the quality of life varies among stratified groups. The kind (primary or secondary) and severity of the stroke, as well as the existence of rehabilitation, are indicators that impact the quality of life of patients who have had ACVA.

Type II diabetes is considered a chronic disease that influences the affected person's quality of life and imposes a high economic burden on the patient and society. The enhancement of health literacy seems essential for self-management and disease control in patients with type II diabetes. Consequently, this study was performed to evaluate the cost-effectiveness of enhanced health literacy in type II diabetes patients.  

This study was of quantitative and economic evaluation type. A population of 232 patients was selected among those referred to the Tafihan Shiraz clinic based on the quality of entry and exit. The health literacy educational intervention was carried out for three months. In order to collect information, researchers used the SF36 questionnaire and the checklist of costs. The Cost Effectiveness Ratio (CER) and Incremental Cost Effectiveness Ratio (ICER) were calculated. Moreover, the costs of each unit of increasing the quality of life before and after the intervention were calculated. A decision was made to determine the cost-effectiveness of the intervention. 

According to the results, 40% of the participants were females, and 34.5% were 30-40 years old. Examination of the quality of life in patients before the intervention indicated that the mean and standard deviation of the patients’ quality of life before the intervention was 18.43±44.99, and the mean and standard deviation of the quality of life after the intervention was 49.57±16.21. Moreover, the patients’ quality of life increased after the educational intervention. The total direct medical costs were $717,484 and $685,620 before and after the intervention, respectively. The total indirect medical costs were $604,122 and $493,011 before and after the intervention, respectively. Moreover, the total indirect costs were $122,535 and $122,119 before and after the intervention, respectively. The study was cost-effective with CER=0.9 and ICER= - 140,000 per increase in the quality of life. 

Improving health literacy can have a range of benefits and improve the quality of life of patients with type II diabetes and reduce their treatment costs, and thereby, this may be seen as an effective step toward the recovery of patients with type II diabetes.

Hydatidosis, a chronic zoonotic disease, has a distribution worldwide and is caused by the larval stage of the Echinococcus helminth. The Dot-ELISA test can diagnose hydatidosis quickly and accurately. Additionally, unlike other hydatid disease tests now used, this quick and affordable enzyme immunoassay is very serum-conservative and antigen-conservative, needing just nanogram levels of parasite antigen.

In the present cross-sectional study, crude and B antigens of hydatid cyst fluid were obtained to diagnose human hydatidosis using CIEP (Counter Immunoelectrophoresis), ELISA (Enzyme-linked Immuno Sorbent assay), and Dot- ELISA (Dot Enzyme linked Immuno Sorbent Assay) methods. Infected liver with a hydatid cyst was collected from Tehran's slaughterhouses to prepare cyst fluid in different stages. After extracting and purifying the Cyst fluid, it is centrifuged at 4ºc, then prepared to concentrate. The study also included sera from hydatidosis (n=60), samples of helminth parasites (n=55), fascioliasis (n=35), toxocariasis (n=20) and negative control (n=35) were tested by CIEP (Counter Immunoelectrophoresis), ELISA (Enzyme-linked Immune Sorbent assay), and Dot- ELISA (Dot Enzyme linked Immuno Sorbent Assay) methods. All statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) for Windows release 25.0 (SPSS Inc., Chicago, IL, USA).   

Crude antigen of hydatid cyst showed a specificity of 76.7%,  a sensitivity of 93.3% using the ELISA method, and B antigen showed a specificity of 96.7% and sensitivity of 88.3% using the same method.
The crude antigen of the hydatid cyst exhibited a specificity of 68.9% and a sensitivity of 86.7% using CIEP. The B antigen showed a specificity of 87.8% and sensitivity of 83.3% using the same method. The crude antigen of hydatid cyst having serum dilution at 1:800 exhibited a specificity of 83.3% and sensitivity of 100% using the Dot-ELISA method and B antigen having serum dilution at 1:800 serum showed a specificity of 100% and sensitivity of 98.3% using the same method. The results of this finding showed that B antigen has the maximum specificity to diagnose hydatid test using the Dot- ELISA method.  

Hydatid cysts present with varied symptomatology. History of exposure to infected animals may not be present. A high degree of clinical suspicion combined with meticulous history and clinical examination supported by laboratory investigations are required for its diagnosis. The Dot-ELISA system with native antigen B is a viable approach for the immunodiagnosis of human hydatidosis that is preferred to infection.

Noise induced hearing loss (NIHL) is an irreversible occupational disease among industrial workers. Recent studies have reported that changes in some metabolic factors such as the serum level of sugar and lipids might have a role in suffering from NIHL among workers exposed to noise. We designed this study to assess the association between lipid profile changes and NIHL occurrence among noise-exposed workers.  

This case-control study has been conducted according to noise-exposed workers registry data in one of the Iranian automobile factories between 2007 and 2017. We classified study workers into the NIHL and control groups. We assessed the impact of lipid profile parameters across the study groups using the independent samples t-test, chi-square, and regression.  

The mean serum level of cholesterol was significantly higher in the NIHL group than in workers of the control group (215.27 ± 60.30 vs 204.49 ± 63.69 mg/dL; P = 0.041). Moreover, the serum level of HDL was significantly lower in workers in the NIHL group compared with the control group (35.21 ± 6.87 vs 37.43 ± 7.28 mg/dL; P < 0.001). Although other lipid profile parameters (LDL, TG, LDL/HDL ratio) were higher among workers of the NIHL group, their differences were not significant.  

A cholesterol level lower than 200 mg/dL is known as a protective factor and an HDL level lower than 40 mg/dL is an NIHL risk factor. More attention should be paid to controlling serum levels of cholesterol and HDL.

Breast cancer is a non-communicable and common disease that accounts for a high percentage of deaths. Early diagnosis of this disease reduces the death rate. Screening methods such as digital mammography can help prevent or identify the disease earlier. Therefore, this study aims to analyze the cost-benefit of breast cancer using digital mammography.  

This systematic review was conducted based on PRISMA 2020 checklist. PubMed, Scopus, Web of Science, ProQuest, Cochrane Library, and Google Scholar were searched without any time limitation on June 2022. The quality of the studies was evaluated with the CHEERS checklist. After data extraction, the results were synthesized by thematic content analysis.  

During the search, 3468 records were identified, of which 1061 were duplicates. 2407 titles and abstracts screened in terms of inclusion criteria. Finally, after studying 20 fulltexts, three of them were included in the study. The quality of these articles was scored between 10 and 16. These studies were from Spain, Denmark, and the United States from 2000 to 2019. Two studies showed that digital mammography is not as effective as other screening methods.  

The results of this study showed that digital mammography is not very cost-benefit for the health care system. An increase in its repetition frequency imposes more costs on the health system and doesn’t have more benefits for it.

More than 15% of the world's population live with some form of disability. Assessing socioeconomic inequalities in disability and monitoring its change over time can help policymakers to design and implement targeted interventions to reduce these inequalities. This study aimed to assess the change in socioeconomic inequality in disability in Iran from 2000 to 2010.  

Data for this cross-sectional study were obtained from 2 waves of Iran’s demographic and health surveys (2000 and 2010). The Wagstaff normalized concentration index was used to measure the socioeconomic inequality of disability. Contributing factors to the inequality in 2000 and 2010 were investigated by concentration index decomposition. The Blinder-Oaxaca decomposition method was used to determine contributing factors of change in disability inequality. All analyses were conducted in Stata14.   

The negative and statistically significant concentration indices (–0.132 in 2000 and –0.165 in 2010, P < 0.001) suggested more concentration of disability among poor people. The absolute value of inequality was increased by 0.034 between the 2 points of time (P = 0.025). Level of education (123.5%), household size (12.9%), age (–35.1%), and residency (in terms of Iran's provinces) (–19.3%) were the contributing factors to the measured disability inequality in 2000. In 2010, level of education (105.8%), household size (30.5%), and urban residency (–46.3%) explained the measured inequality. Change in disability inequality was explained by household size (99.4%), province of residence (54.8%), education (36.9%), socioeconomic status (20%), urban residency (–90.3%), and age (–47.7%).  

Iran suffers from significant socioeconomic inequality in disability, and it significantly increased over time. Interventions such as increasing health literacy and providing suitable job opportunities for people with low education level, improving the socioeconomic status of extended households, and paying more attention to the balanced development in the provinces and urban and rural areas, and attending to prevention, treatment, and mitigation of disability adversities among poor young and elderly people could be recommended to tackle increased socioeconomic inequality in disability and its unfavorable consequences in Iran.

This short communication reflects on this year’s mental health day. The theme for this year is ‘Mental health is a universal human right’. However, here the  focus is on simple instances (politeness, and the culture of apology) to highlight how these could contribute to improved psychological well-being and mental health. It is hoped that by insisting on such deeds we could spread kindness in our community to make it a safer place for living and make life more enjoyable regardless of its all difficulties and limitations.

Severe and critically-ill COVID-19 patients are characterized by a severe inflammatory response. Pharmacologic inhibition of acute-phase inflammatory pathways such as IL-6 receptor inhibitor, Tocilizumab (TCZ) may improve patient outcomes in these cases. Consequently, the therapeutic benefit of TCZ was evaluated in this study.  

We evaluated intravenous tocilizumab in severe and critically ill adult COVID-19 patients who met pre-defined stringent CRS criteria. A single-center, prospective, observational cohort study was carried out among consecutive adult (≥18 years of age) in-patients with COVID-19 between March 20, 2020 and March 20, 2021. In total, 354 patients were included in our study. Mortality and time to hospital discharge were compared between patients who received tocilizumab treatment (n = 177) and those who did not  (n = 177).

A total of 354 patients were analyzed whereas 177 patients were included in each group. In those receiving TCZ, all-cause mortality was significantly reduced, corresponding to an adjusted hazard ratio (HR) of 0.57, (95% confidence interval (CI): 0.43-0.76; P < 0.001). Furthermore, time to discharge was significantly improved in the TCZ group (HR: 1.66; 95%CI: 1.17-2.36, P = 0.004). Invasive mechanical ventilation was not statistically different among the study groups after adjusting for confounding variables (HR: 1.38; 95%CI: 0.89-2.14; P = 0.139). Dosing frequency was independent of survival status (P = 0.676).

The use of TCZ in ICU-hospitalized patients resulted in improved patient survival and reduced duration of hospitalization. Further studies are needed to confirm the efficacy of TCZ in severe and critical COVID-19 cases.

Believability and thoughts are considered as the pillars of behaviors over time, and anxious feelings are a risk factor for mental disorders, especially during the coronavirus disease (COVID-19) pandemic. This study aimed to explore the thought believability and anxious feelings of COVID-19 among infected and healthy families.  

In this hospital-based matched case-control study, health surveillance files of COVID-19 patients were collected from January to June 2021 and were analyzed statistically. In this study, two questionnaires of demographic characteristics and the Believability of Anxious Feelings and Thoughts (BAFT) were used. Data were analyzed using the One-way ANOVA.  

Of 600 participants, 300 (50%) were PCR-confirmed and 300 (50%) were non-infected. Overall, 163 (54.33%) of infected people were male, 146 (48.67%) single, and 156 (52.00%) government employees. The results showed that the mean scores of physical anxiety (PA) and negative evaluation (NE) in the case group is significantly higher than the control group (P = 0.001); while emotional regulation (ER) in the control group was significantly higher than the case group (P = 0.001).  

Having high believability to the risks of COVID-19 may be a predictor of preventive behaviors in individuals. Worrying about COVID-19 can increase the perceived risk of a pandemic in societies and consequence, increase the general public health.

One of the indicators of development in different countries is the efficiency of the health care system. Hospitals and health centers have a very important role in the sustainability of society as w well as its economic growth and development. Meanwhile, one of the important development indicators of hospitals is good governance. This study was aimed to determine the factors affecting good governance in teaching hospitals.  

This study was a scoping review of Iranian databases, including IranDoc, ISD, Magiran and International databases such as Science Direct, ISI, PubMed and Scopus to meet the good governance factors in teaching hospitals. There were no time limitations to data collection. the keywords governance, good governance, hospital governance, and good governance in hospitals, teaching hospitals, hospital management, hospital leadership, and their synonyms were used in the search strategy. The content analysis method was used to analyze selected studies.  

The findings showed that the characteristics of effective governance in teaching hospitals can be considered as follow: efficiency, managing conflict of interests, facilitated operation, managed and under control activities, integration, and synergy, achieving the desired consequences, creating an atmosphere that is rewarding and for each member. 

Based on the results regarding the good governance model in teaching hospitals, it is recommended that on the basis of the nature of service, the mission and value of teaching hospitals have to be clearly redefined. On the other hand, the methods based on which we treat patients should be seriously redefined and we should pay more attention to the patient's values because the patients feel that we are practicing and testing them.

Randomized controlled trials (RCTs) provide the strongest evidence for therapeutic interventions and their effects on groups of subjects. However, the large amount of unstructured information in these trials makes it challenging and time-consuming to make decisions and identify important concepts and valid evidence. This study aims to explore methods for automating or semi-automating information extraction from reports of RCT studies.  

We conducted a systematic search of PubMed, ACM Digital Library, and Web of Science to identify relevant articles published between January 1, 2010, and 2022. We focused on published Natural Language Processing (NLP), machine learning, and deep learning methods that automate or semi-automate key elements of information extraction in the context of RCTs.  

A total of 26 publications were included, which discussed the automatic extraction of key characteristics of RCTs using various PICO frameworks (PIBOSO and PECODR). Among these publications, 14 (53.8%) extracted key characteristics based on PICO, PIBOSO, and PECODR, while 12 (46.1%) discussed information extraction methods in RCT studies. Common approaches mentioned included word/phrase matching, machine learning algorithms such as binary classification using the Naïve Bayes algorithm and powerful BERT network for feature extraction, support vector machine for data classification, conditional random field, non-machine-dependent automation, and machine learning or deep learning approaches.  

The lack of publicly available software and limited access to existing software makes it difficult to determine the most powerful information extraction system. However, deep learning models like Transformers and BERT language models have shown better performance in natural language processing.

Excessive screen time has been associated with a variety of negative health outcomes. We aimed to evaluate screen time and phone and tablet use in Iranian adolescents and their relation to the socioeconomic status of adolescents’ families in 2018.  

This descriptive-analytical study was carried out on 10-12-year-old adolescents from Kurdistan, Fars, and Markazi provinces. Cluster sampling was used for sampling. Data were collected by completing demographic questionnaires, calculating the BMI of adolescents and phone and tablet use, screen time, and socioeconomic status of the families. We used linear and logistic regression to estimate the final model. The concentration index was used to measure inequality and the Oaxaca decomposition to examine the different determinants of the inequality.  

1590 adolescents (52.58% boys) were enrolled in our study. Screen time activities were significantly higher in boys, older adolescents, higher BMIs, more educated mothers, and 35< year-old fathers (P < 0.05). The use of mobile phones and tablets was significantly higher among boys, ten-year-olds, families with four or fewer members, higher BMIs, adolescents with higher levels of parental education, and more educated mothers (P < 0.05). In addition, the concentration index for screen time activities (C = 0.083) and phone and tablet use (C = 0.536) showed that screen time and phone and tablet use activities were higher in adolescents with high socioeconomic status.  

Screen time, phone and tablet use were higher in adolescents with high socioeconomic status. Also, many other factors like gender, age, BMI, parents' education and age can affect screen time, phone and tablet use in adolescents.

The Coronavirus disease 2019 (COVID-19) pandemic showed the importance of simple, low-cost, and accessible tests for patient triage. Complete Blood Count (CBC) can be considered a good option for predicting the prognosis of COVID-19 and daily follow-up of hospitalized patients.  

CBC tests of 100 COVID-19 patients admitted to the general ward or intensive care unit (ICU) were monitored for ten days. Routine laboratory tests were also performed. In addition, the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were calculated at the time of admission.  

The WBC count of the ICU-admitted patients was significantly lower than in the non-ICU-admitted group (P = 0.008). The mean lymphocyte percentage of deceased patients was significantly lower than in the survived patients (P = 0.041), whereas the mean neutrophil percentage of the former group was higher than the latter (P = 0.012). Moreover, the mean monocyte percentage of the survivors was significantly more than that of non-survivors (P = 0.003). However, there was no significant difference in mean platelet counts, hemoglobin levels, and red blood cell count between the studied groups.  

A lower WBC, lymphocyte percentage, and monocyte percentage, in addition to a higher neutrophil percentage, may indicate a poor prognosis in moderate to severe COVID-19 patients.

Life course research has shown that socioeconomic conditions in childhood have a profound impact on adult health. However, little is known about the different health effects of social mobility. This study was conducted to answer whether the intergenerational social mobility of women in Rasht is related to their quality of life index.  

This cross-sectional survey conducted in 2020–2021, in which the researcher created a social mobility questionnaire, was used to study the association between social mobility and the quality of life index of women aged 30-65 in Rasht. The current socioeconomic status of 784 married women in this city was compared to the previous socioeconomic status of their parents. Also, Ferrans and Power's quality of life index questionnaire was used. Data analysis was done using t-test and ANOVA.  

The mean (SD) score for the overall quality of life index was 21.60 (4.23) of 30. The majority of participants had immobility (350 of them or 44.6%). There was no statistically significant correlation between women's intergenerational mobility and their quality-of-life index (P = 0.734). Still, there was a statistically significant difference between the average score of the quality of life in the socioeconomic groups of the participants.  

Findings show that the women in Rasht did not have opportunities to promote their status or could not take advantage of these possibilities. Although our results did not show evidence for the effects of social mobility on quality of life, some scholars’ findings support the idea of the impact (negative or positive) of intergenerational upward mobility on well-being.

 Concerns about the side effects of SARS-CoV-2 vaccines have been raised nationwide. We aimed to compare the time to report the side effects of the Oxford-AstraZeneca and Sinopharm COVID-19 vaccines. 

 Information on side effects of AstraZeneca and Sinopharm COVID-19 vaccines was obtained from the COVID-19 Symptom Study App affiliated with Shiraz University of Medical Science during 2021. A COX regression model with an adjusted Hazard Ratio and 95% Confidence Interval; HR (95% C.I) was reported at the significance level of < 0.05.  

 4478 and 5555 participants received the AstraZeneca and Sinopharm vaccines, respectively; more age, history of SARS-CoV-2 infection, first vaccine dose, hypertension, and hypertension with cardiovascular disease were seen in the AstraZeneca group (P < 0.05 for all). However, the AstraZeneca group had lower immune deficiency and time to report the side effects (P < 0.05 for both). There was significantly less time to pain HR(95% C.I.); 0.50 (0.47-0.52), vertigo 0.65 (0.61-0.69), weakness 0.41 (0.38-0.44), headache 0.43 (0.39-0.74), anorexia 0.31 (0.28-0.34), nausea 0.56 (0.51-0.62), severer allergy 0.71 (0.63-0.81), general inflammation 0.27 (0.23-0.31), fever > 38oC 0.12 (0.1-0.15), eye inflammation 0.45 (0.39-0.52), diarrhea 0.85 (0.73-0.99), blurred vision 0.73 (0.61-0.86), injection site redness 0.32 (0.26-0.39), fatigue/paleness 0.53 (0.50-0.57), joint pain 0.55 (0.41-0.73), auxiliary gland inflation 0.59 (0.43-0.80), convulsions 0.30 (0.17-0.52), and severe side effects 0.3 (0.27-0.33) in the AstraZeneca group; However, skin rash 0.77 (0.57-1.05) and hospitalization 0.72 (0.21-2.55) were the same.  

 Sinopharm COVID-19 vaccine recipients reported longer times to report vaccine-related side effects than AstraZeneca; due to the lack of adverse effects like hospitalization, vaccination should continue to control the pandemic; more real-population studies are needed on the long-term effects of vaccination against COVID-19.

Despite all the advancements and publicity made in regard to classical medicine, every day more and more people are interested in complementary medicine. This study was designed and conducted to determine the relative frequency of the use of Persian traditional medicine services by the people of Tehran.

This cross-sectional study was conducted using the telephone survey method in Tehran. A total of 1824 samples were included in the study based on Cochran's formula. At first, by searching databases, including Google Scholar, PubMed, Embase, and internal sources, including the Iran Medex database, numerous medical texts and articles were reviewed in the field of using traditional medicine services. Then, interview guide questions were designed and asked over the phone. Finally, the data were extracted and subjected to quantitative analysis. Frequency and percentage of relative frequency were used to describe the study data.

In the study, 62% (n = 1131) of the participants were women, and 60.5% (n = 1103) of the participants have turned to modern medicine for treatment and have also used traditional medical treatments. Also, 43.5% (n = 864) of the participants have used herbal medicines and their products; 43% (n = 616) of the participants have used Persian traditional medicine treatments as selftreatment based on their personal information; and only 46.5% (n = 666) have evaluated the therapeutic effect of Persian traditional medicine methods as “good.”

The results of the study indicate the need for more emphasis on Persian traditional medicine alongside modern medicine, more organization and supervision of traditional medicine service providers in the country, and the creation of coherent and integrated management in this field.

Detection of cancer in patients with thyroid nodules requires sensitive and specific diagnostic modalities that are accurate and inexpensive. This study aimed to identify a potential microRNA(miRNA) panel to detect papillary thyroid carcinoma (PTC).

Following a comprehensive literature review as well as miRNA target predictor databases, Real-time PCR was used to quantify the expression of candidate miRNAs in 59 tissue specimens from 30 patients with PTC and 29 patients with benign nodules. A receiver operating characteristic (ROC) curve analysis was used to assess the accuracy of miRNA expression levels compared to the pathology report as the gold standard. Based on prediction results, four miRNAs, including miR-9, miR-20b, miR-221, and miR-222, were selected to evaluate their expression level in Iranian thyroid samples.

A significant difference between the tissue expression level of miR-20b, miR-9, miR-222, and miR-221 was detected in the PTC group compared with non-PTC (P < 0.05). The area under the curves for the included miRs were 1, 0.98, 0.99, 0.98, and 1, respectively.

Our results confirmed deregulations of miR-20b as well as miR-222, miR-221, and miR-9 in PTC and, therefore, could be used as a helpful miRNA panel to differentiate PTC from benign nodules, which results in the more efficient clinical management of PTC patients.

One of the critical factors affecting chronic diseases is the use of drugs, especially industrial substances, such as methamphetamine. Methamphetamine use is increasingly common among the younger members of society. Methamphetamine is not only physically and mentally destructive, but also has a significant impact on the families of abusers and society, and imposes a financial burden on society. The present study aims to identify the factors affecting methamphetamine use in a scoping review.

Different keywords of methamphetamine were selected in the Mesh database and were searched in valid English databases from January 1, 2008, to April 5, 2022. Inclusion and exclusion criteria in this study were languages, reported findings, time range, and type of article. This study was designed by scoping review method developed by Askey Malley’O.

The total articles that were finally analyzed in this article were 42 including 12 English articles and 30 Persian articles. Among these articles, the most important factors affecting Methamphetamine are individual, social, and family factors, which have received the most cited.

The majority of research highlights the importance of individual factors, society, and family factors, respectively, while formulating policies for prevention, treatment, and rehabilitation must be considered. It is suggested that structural path analysis be determined by prioritizing the identified factors and the weights of these components

Dependence in bathing is the most common activities of daily living (ADLs) dependency among older adults. The aim of this study was to evaluate the effect of bathing skills training on the independence and satisfaction of older adults living in nursing homes.

In this randomized controlled trial, 80 participants were assigned randomly to the intervention (n = 40) and control groups (n = 40). The intervention group received 10 weekly bathing skills training sessions, with each session lasting about 60 minutes, while the control group received no direct training. The evaluation was conducted using the Modified Barthel Index (MBI) and the Canadian Occupational Performance Measure (COPM). Analysis of variance for repeated measurements was used to test the effect of intervention at the baseline, post-intervention, and follow-up.

The mean improvement in the MBI was greater for the intervention group (P < 0.001; partial η2 = 0.34), which remained significant at the follow-up (P < 0.001; partial η2 = 0.41). The greater mean change of the COPM–Performance was significant in the intervention group (P < 0.001; partial η2 = 0.17), which remained significant at the follow-up (P < 0.001; partial η2 = 0.19). The greater mean improvement of the COPM–Satisfaction was observed for the intervention group (P < 0.001; partial η2 = 0.36), which remained at the follow-up (P = 0.001; partial η2 = 0.42).

Bathing skills training is effective in improving the ADLs independence and satisfaction in older adults living in nursing homes; thus, it is recommended to be included in the schedules of nursing homes.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by severe communication deficits and limited and repetitive behavioral tendencies. There are several treatment approaches and methods for minimally verbal children with ASD; nonetheless, there is inconclusive evidence about how early lexical development could be improved. The present study aimed to investigate the effect of combined intervention derived from the principles of different theories—including contemporary behaviorism, schemas, sociocultural, and event representation theories—to improve early lexical development in minimally verbal children with ASD.

In this single-group pretest-posttest study, 10 children with ASD (mean age, 47.9 ± 8.3 months), including 7 boys and 3 girls, participated. Participants received 16 intervention sessions in 8 weeks. The combined intervention consisted of various methods derived from contemporary behaviorism, schemas, sociocultural, and event representation approaches. The MacArthur-Bates Communicative Development Inventory 1 (Infant form) assessed early lexical development before and after intervention and after a 2- month follow-up. The Friedman test was used to analyze the data, and pairwise comparisons were performed with the Will-Coxon test. Cohen's d was used to investigate the effect sizes.

Significant increases in expressive vocabulary (P < 0.001) and receptive language (P < 0.001) were seen after the end of the intervention and at the follow-up (P = 0.005). Large effect sizes were found for expressive vocabulary (d = 3.7) and receptive vocabulary (d = 2.17).

This study suggests that the combination of intervention based contemporary behaviorism, schemas, sociocultural, and event representation approaches improved receptive and expressive vocabulary in minimally verbal children with ASD.

Many patients do not have a clear idea about the recovery from COVID-19 infection. This study focuses on the prevalence of persistent symptoms of COVID-19 infection as well as new symptoms that appear after recovery, and it aids in determining the relationships between these symptoms and a variety of variables.

An online observational study was conducted between April and June 2022. It consisted of a self-administered web-based questionnaire conducted using social media platforms. Inclusion criteria were residency in Jordan, being 18 years of age or older, having recovered from COVID-19 for at least 90 days, and giving consent to participate. Participants whose infection was not confirmed by a positive PCR were excluded.

The most common persistent symptoms were loss of smell (34.7%), fatigue (34.6%), loss of taste (29.5%), myalgia (26.3%), and headache (25.9%), while the most common newly appearing symptoms after recovery were smell hallucinations (15.8%), fatigue (15.5%), taste hallucinations (14.9%), and focus impairment (12.9%) and smell impairment (12.8%). The symptoms persisted more in females, non-smokers, and those who needed medical care sor oxygesnation and with increased infection duration.

The study about persistent and new symptoms after COVID-19 among Jordanians found a greater prevalence of symptoms related to the sense of smell. There is no association between persistent and new symptoms after COVID-19 recovery with comorbidities or oxygen therapy during illness. We recommend studying the effect of COVID-19 mutants and vaccination on the persistence of symptoms after recovery.

Providing unnecessary healthcare services is a major common problem in every health system. The scope and cause of healthcare services must be identified in order to be managed and controlled. Finding the most complete definition of the problem and its causes are the goals of this meta-synthesis.

A comprehensive search strategy was performed using a wide range of keywords and databases. Based on the defined inclusion and exclusion criteria, 22 articles were selected for content analysis and meta-synthesis. The Graneheim and Lundman method was used for content analysis. The MAXQDA software Version 18.2.0 was used for the first round of content analysis. Content analysis and meta-synthesis were used to comprehensively define the term “unnecessary healthcare services” and find the etiologic factors driving healthcare providers to unnecessary healthcare services.

The term “unnecessary healthcare services” is defined as “overproviding healthcare services that could be harmful, lowvalue, insufficient, and inappropriate.” The etiologic pattern of unnecessary healthcare services shows intrinsic and extrinsic factors as a driving force for unnecessary healthcare services.

A multilayer strategy for efficient management and prevention of unnecessary healthcare services is appropriate due to the multifaceted character of these services. This approach consists of the modification of the intrinsic factors and extrinsic drivers.

The paraspinal muscles, including multifidus (MF) and erector spinae (ES) play key roles in the stability and movement of the lumbar spine. This study aimed to determine the intra-rater reliability of the ES and MF muscle thickness measures of the rehabilitative ultrasound imaging (RUSI) in people with active extension pattern (AEP) non-specific chronic low back pain and controls.

Fifteen females with AEP and 19 controls participated in this test-retest intra-rater reliability study, including two different testing sessions performed in four to seven days apart. The primary (raw) and derived (normalized) measures of the L4 MF and ES muscles`thickness were examined in three different positions (prone, sitting, and standing) on both days. A two-way mixed average of intra-class correlation coefficient (ICC3, K) with confidence interval (CI = 95%) was used to determine the relative reliability. The standard error of measurement (SEM) and minimal detectable change (MDC) values at a CI of 95% were computed to examine the absolute reliability.

The ICC values for the primary thickness of the L4 ES and MF muscles were from 0.85 to 0.91, except for MF muscle thickness in standing (ICC = 0.67) and sitting (ICC = 0.66) positions . The ICC values for derived data were lower in both groups. The SEM and MDC values were small enough to confirm the absolute reliability of the primary data.

This study supports the use of RUSI for examining the primary measures of the L4 MF and ES muscles in asymptomatic and AEP participants, but it should be used cautiously for assessing the derived measures.

This article presents a mathematical justification for a new approach to arthroscopic stitching of the knee joint meniscus, based on a 3D computer model of the meniscus developed using the COMPASS-3D (APMFEM) program and AutodeskInventorPRO. The research with the patent RK No. 35413 dated 10.12.2021, titled "Method of arthroscopic stitching of the meniscus of the knee joint" builds upon the work of Yu.V. Labunsky.

Mathematical analysis was performed to compare two methods of stitching the meniscus: the new oblique-vertical stitch and the classical vertical stitch. The contact area of the meniscus tissues in the area of the rupture was measured for both stitching methods.

The findings demonstrate that the new oblique-vertical stitch offers a 1.5 times larger contact area of the meniscus tissues in the area of the rupture, compared to the classical vertical stitch. Additionally, the new method provides a more significant grip on the radial and circular fibers of the meniscus, surpassing the capabilities of the classic seam.

The results of this study can be utilized to develop practical recommendations for traumatologists regarding arthroscopic stitching of the meniscus in the knee joint. The new approach, supported by mathematical analysis and a 3D computer model, offers improved outcomes in terms of contact area and grip on the meniscus fibers, potentially leading to enhanced surgical techniques and patient outcomes.

Autonomic Dysreflexia (AD) is a crucial emergency complication of cervical and upper thoracic spinal cord injury (SCI). Although there are several treatment options for AD, unfortunately, there is no consensus on the treatment of AD. This study aimed to present Clinical Practice Guidelines (CPG) development for AD in SCI in different conditions.

The project was carried out by an executive team of general practitioners and neurosurgeons. A national multidisciplinary panel of experts performed the decision-making step, which consisted of deciding on the final list of recommendations and articulating novel recommendations regarding the infrastructure and fundamental elements necessary for managing patients suffering from AD. Four appraisers evaluated the guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE II) tools.

A total of 575 articles were found after searching different databases. After the primary screening, title, abstract, and fulltext screening were performed, which yielded 9 records. Five were excluded after the AGREE II evaluation. The source guidelines’ recommendations were tabulated as possible scenarios for 15 patient/population, intervention, comparison, and outcomes clinical questions. Based on the expert panel’s opinion, all the recommendations were adaptable. Finally, the suggestions were transformed into a protocol for managing patients suffering from autonomic dysreflexia.

This guideline presented the treatment and pharmacotherapy of autonomic dysreflexia. However, the treatment is being updated. We suggest more educational multimedia for health care professionals, primarily in the emergency department.

This study aimed to investigate the factors related to absconding and consequences of absconding in a psychiatric hospital in a developing country within 3 years.

This was a retrograde descriptive cross-sectional study from a psychiatry hospital in a developing country, Iran. The registered data of absconding between March 2018 and February 2021 were extracted. Furthermore, a retrograde follow-up by telephone on what happened after the absconding and the remembered motives was done. The obtained data were analyzed using SPSS statistical software for Windows Version 23 by descriptive statistics. The chi-square test, Fisher exact test, Student t test, or Mann–Whitney U tests were used for data analysis. P ˂ .05 was considered statistically significant.

Out of 7069 admitted patients during a 36-month period, 51 (39 men and 12 women) had absconded. The total absconding rate was 0.72%. The mean ± (SD) age of the patients was 29.7 ± (10.46) years, with a range of 10 to 54 years. No statistical difference between men and women emerged in terms of age (P = 0.89). Most of the absconders were men (76%), young (mean age, 29.7 years), single (70.6%), and involuntarily hospitalized (78.4%) in an urban area (90.2%), and absconded in the evening shift (58.8%) via the route of the main gate (58.8%) in the early days of admission (5 days). In terms of psychiatric diagnosis, the highest rank belonged to bipolar disorder (33.33%) and substance-related disorders (33.33%). About one-third of absconders had a current substance-related problem and most of them had experienced withdrawal symptoms or cravings days before absconding (75%). Absconders mentioned that “no need for admission” (45.1%), “economic problems” (23.5%), and “substance craving” (13.7%) were the most common reasons for leaving the hospital. Most of the absconders were hospitalized later (70.5%). The risk for self-harm (21%) or harm to others (2%) after absconding was low.

The general profile of absconders was concordant with previous studies. It was highlighted that economic problems in recent years had an evident impact on patients and it could be postulated that consideration of substance withdrawal may decrease absconding. It is advised to adhere to the policies that support community-based psychiatry and place an emphasis on early discharge and continuity of outpatient care.

This qualitative study was designed to investigate parental adherence to cranial remolding orthotic (CRO) treatment of infants with positional cranial deformities.

A qualitative content analysis was employed in this study. Researchers sought to find parental behavior while using a CRO for their infant with cranial deformity. Through in-depth and in-person interviews, researchers collected data from 22 participants using semi-structured questions regarding adherence to CRO treatment. Data were examined for patterns until saturation occurred, yielding categories that focused on the parents’ main barriers and facilitators.

Two general themes of “potential barriers to CRO treatment adherence” and “potential facilitators to CRO treatment adherence” were extracted from 12 subthemes of parental burden, transportation, availability of CRO services in hometown, financial responsibility, maternal/paternal attachment attitudes, CRO-related problems, others feedback, adjustment to the treatment, motivation and self-confidence, aesthetic satisfaction, communication with orthotist, and wife's empathy/spousal support.

Getting time off work, transportation to the orthotics’ clinic, the lack of medical insurance coverage for CRO, reduced physical contact between parents and their child, and getting negative feedback from others were the most reported challenges. However, overcoming the initial difficulties and adjustment to the treatment with CRO, the high motivation of parents during therapy, an orthosis with good fitting and minor complications, a strong relationship between the parents and orthotist, and the father's companionship were revealed to facilitate the treatment process and increase adherence of treatment with CRO.

The COVID-19 pandemic affected educational institutions and caused the transfer to distance learning. The study aimed to assess medical students' satisfaction with synchronous distance learning (SDL) during the pandemic and predict their choice of it in the future.

A cross-sectional study was conducted among undergraduate medical students at the Al-Farabi Kazakh National University in July 2021. An online questionnaire was used to collect data on demographic and educational characteristics, satisfaction, and perspective on the future choice of SDL. IBM SPSS Statistics, version 26, was used to analyze the qualitative data on descriptive and inferential statistics.

Students' satisfaction and future choice of SDL were 43.2% and 20.2%, respectively. Regression analysis revealed the significance of SDL predictors with a direct relationship in the case of gender and academic performance and predictors with an inverse relationship in the case of residency, student life satisfaction, and SDL with student satisfaction. In the predictive model, student satisfaction and probability of future choice of SDL over traditional learning were 59.5% and 43.5%, respectively; over hybrid learning, it was 20.2% of students.

The research findings suggested that slightly less than half of the respondent medical students were satisfied by distance learning during the COVID-19 pandemic when their satisfaction probability was significantly higher in the predictive model. The predictive model of perspective of choice of distance learning did not show statistically significant results compared with traditional and hybrid learning.

Distal radius fractures are one of the most common upper extremity fractures, and their incidence continues to increase due to an aging population and an increase in osteoporosis. Various methods of analgesia for distal radius fractures have been described—including hematoma blocks and nerve blocks. Hematoma blocks are a simple and effective method of providing analgesia; nonetheless, their efficacy may be limited in some cases. On the other hand, nerve blocks provide more targeted analgesia and may be more effective in reducing pain during fracture reduction. This study aimed to compare the analgesic effectiveness of radial and median nerve blocks with hematoma blocks under ultrasound guidance in treating distal radius fractures. Also, this study aimed to compare the analgesia of radial and median nerve blocks with hematoma blocks under ultrasound guidance to reduce distal radius fractures.

In this prospective trial, patients with distal radius fractures referring to 2 academic centers were placed into 2 randomized groups, including hematoma block, and radial median block, both of which were ultrasound-guided. The patient's pain levels were measured and recorded based on the visual analog scale before the block, 5, 10, and 15 minutes after the block, at the start of reduction, during reduction, and 5, 10, and 15 minutes after reduction. Patient satisfaction and physician satisfaction rates were assessed, and side effects were also observed for 1 week. Quantitative variables were reported as mean ± standard deviation, and number and frequency percentages were reported for qualitative variables. The Student t test and the chi-square test were used on a case-by-case basis. The significance level was set at P ˂ 0.05.

In this study, 120 patients were included. The groups had no significant differences in pain reduction during the procedure. Analgesic medication was needed during the procedure for 17 patients; nerve blocks were applied for 6 patients, and hematoma blocks for 11 patients, which was statistically significant (P = 0.041). Satisfaction rates for patients and physicians performing the procedure were significantly higher in the nerve block group than in the hematoma block group (P = 0.001; P ˂ 0.001, respectively).

The results of this study suggest that ultrasound-guided radial and median nerve blocks can be used as alternative methods of analgesia with other techniques in the reduction of distal radius fractures in emergency departments.

Determining the risk of severe course coronavirus disease 2019 (COVID-19) and its related factors in survivors of common cancers such as breast cancer is important. This study has been designed to evaluate the prevalence of COVID-19 infection in breast cancer survivors and also estimate the risk of severe disease in this population.

Out of 6134 patients in the Shiraz Breast Cancer Registry (SBCR), A total of 292 patients who elapsed less than a year from their breast cancer diagnosis were excluded. We called 5842 patients. Finally, 4135 breast cancer survivors who agreed to cooperate were screened for COVID-19 symptoms by a symptom-based questionnaire in November 2020. COVID-19 in symptomatic participants was confirmed by a polymerase chain reaction (PCR) test. The clinical and paraclinical data of the COVID-19 course were collected for patients with a positive PCR test.

A total of 247 (5.9%) participants had at least reported one of the COVID-19 symptoms. Also, 17% of symptomatic participants had a positive PCR test; 83.7% had mild disease, 9.5% moderate, and 16.7% had severe conditions. Chronic cardiovascular disease, hypertension, and diabetes were related to an increased risk of severe illness (P = 0.018, P = 0.018, P = 0.002).

This study suggests that breast cancer intermediate and longtime survivors without other underlying diseases are considered at low risk for developing severe/critical COVID-19.

Human immunodeficiency virus (HIV) resulted in considerable morbidity and mortality. Following antiretroviral therapy (ART), the life expectancy of HIV-infected patients increased; however, they were more at risk of developing chronic diseases such as endocrinopathies. This study aimed to determine the prevalence of dysglycemia, dyslipidemia, and metabolic syndrome among patients with HIV infection.

This cross-sectional study was conducted on HIV-infected patients referring to Loghman Hakim Hospital (Tehran, Iran) between April 2020 and April 2021. We examined demographic features, medical history, and laboratory tests indicating the metabolic status of the patients. Eventually, collected data were processed using SPSS version 23.

The mean age of 68 confirmed HIV patients was 39.85±10.54 years and 64.7% were male. BMI (MD = 2.57, 95% CI = [0.25, 4.88], P = 0.035), cholesterol (MD = 22.73, 95% CI = [4.70, 40.76], P = 0.014), HDL (MD = 8.54, 95% CI = [2.06, 15.02], P = 0.011), and LDL of women was significantly higher than men (MD = 22.43, 95% CI = [7.60, 37.27], P = 0.004). Additionally, 30 patients (44.1%) suffered from metabolic syndrome. The prevalence of metabolic syndrome differed significantly between men (34.1%) and women (62.50%) (P = 0.024).

Dysglycemia, dyslipidemia, and metabolic syndrome are common among HIV-infected patients. Thus, periodic evaluation of the patients can be advantageous in early diagnosis and timely treatment.

Total hip arthroplasty (THA) is an effective surgery for patients with end-stage hip joint degenerative arthritis. This study aimed to determine peri-operative factors that impact the length of stay (LOS) and design a formula to predict LOS in patients undergoing THA.

This cross-sectional study was performed from September 2019 to January 2020. For this study, all patients who underwent THA over a period of 12 years since 2005 were included in the study. Data about the LOS and several variables including demographic variables, surgery-related variables, transfusion, intensive care unit (ICU) admission, past drug history, comorbidities, and laboratory data, were gathered. Qualitative variables are presented as numbers (%), and quantitative variables are presented as mean Mann± standard deviation. Mann Whitney test , Kruskal-Wallis test, and Spearman’s rank correlation test were also used.

A total of 524 patients were included in the study; 12 were excluded .261 (51%) were female and 251(49%) male. The mean age was 56.13±17.04 years. In the univariate analysis, the day of admission, surgery indication, transfusion, diabetes mellitus, oral anti-diabetic drugs, American Society of Anesthesiology (ASA) score, preoperative hemoglobin (Hb) level, and type of prosthesis showed significant relation with LOS. Significant variables entered to zero truncated negative binomial regression. Among them, the day of admission, ASA score, preoperative Hb level, and type of prosthesis showed significant relation with LOS (P < 0.05) and were used for model design.

Preoperative Hb level, ASA score, day of admission, and prosthesis type have an impact on LOS and can predict LOS in patients who are candidates for THA.

Due to the prevalence of autism spectrum disorder (ASD), these children must be screened as soon as possible and receive the necessary and appropriate treatment. The purpose of this study was to examine all the ASD screening tools and examine their psychometric properties in available languages.

This was a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to review the articles published between 2000 and 2023 and were published in PubMed, EMBASE, ProQuest, and Scopus databases. English keywords were as follows: autism spectrum disorders (ASD), screening/screen, tools, psychometric properties, validity, reliability, translations, pervasive developmental disorders (PDD), and children. The COnsensus -based Standards for the selection of health Measurement Instruments (COSMIN) checklist were used to investigate the psychometric properties of the studies.

Among the 476 primary studies, 35 ASD screening tools (132 articles related to the psychometric properties of 35 ASD screening tools in different languages) were identified based on our criteria, and their psychometric properties were examined. Various tools, including performance-based, direct observation, interactive play, and parent and teacher reports tools, were included in the list of tools.

Considering that each of these tools has advantages and limitations, they need to be selected and used according to the goals of the researchers and the therapists. Another important point is that many of these tools still need more extensive studies in relation to their psychometric properties.

Research data on hospitalized coronavirus 2019 (COVID-19) survivors indicate the persistence of symptoms, radiological abnormalities, and physiological disorders months after the initial infection. Given the scale of the ongoing pandemic, a substantial number of patients with severe residual pulmonary fibrosis (PF) and oxygen dependence are anticipated. Currently, the search for risk factors associated with the development of fibrotic radiological abnormalities after moderate to severe COVID-19 is underway. Furthermore, the extent to which computed tomography (CT) data correlate with postdischarge symptoms and physical functions remains unclear. This study aimed to characterize patients experiencing persistent pulmonary consequences after hospital discharge. We examined clinical, radiological, and laboratory predictors of pulmonary fibrosis after COVID-19 infection.

We retrospectively evaluated fibrosis-like lung changes and their prognostic factors in COVID-19 survivors. Our study included 77 patients with laboratory-confirmed COVID-19 who received inpatient treatment at City Clinical Hospital No. 1 in Almaty between November and December 2020. We assessed patients during the acute phase of the disease and again 6 to 8 months after discharge using high-resolution computed tomography (CT). Patients were classified into 2 cohorts based on semi-quantitative analysis of subsequently added tomograms—those with radiological fibrosis-like abnormalities (main group) and those who had recovered (control group).

Parenchymal cords, irregular interfaces, reticulation, and traction bronchiectasis were common CT findings among all COVID-19 patients. Our study focused on patients who developed pulmonary fibrosis within 1 month after the onset of the disease. After 6 to 8 months, fibrosis-like lung changes persisted in 49.35% of patients (leading group), while 50.65% showed disease resolution (control group). Age, body mass index, high interleukin-6 (IL-6) levels, low IO levels, and the need for mechanical ventilation were identified as prognostic indicators for the persistence of pulmonary fibrosis.

Our study revealed that pulmonary function can return to normal in over half of COVID-19 patients 8 months after infection onset. Despite advancements in COVID-19 treatment, there remains a significant knowledge gap in managing long-term effects, especially pulmonary fibrosis. Continued clinical trials and research on post COVID-19 fibrosis are essential to prevent early mortality due to the long-term impacts on these patients.

Studies examining narrative production skills in children with autism spectrum disorder (ASD) have demonstrated variable and inconsistent results. This study aimed to investigate to what extent narrative difficulties in children with ASD reflect difficulties with language.

Accordingly, the spoken narrative skills of 16 children with ASD were compared with those of their 16 chronological agematched (CAM) and 16 language-matched (LM) peers. A Kruskal-Wallis non-parametric test was then used to examine the differences between groups in regard to NTC, NSG and SI variables .For other studied variables (NTW, number of T-units, ATL and total score), one-way analysis of variances (ANOVA) was also used.

At the level of microstructure, the results showed that productivity (number of total words, total clauses, and T-unites) and syntactic complexity (average of T-unit length and subordination index) were predominantly similar in ASD and LM children. However, children with ASD scored lower than their CAM counterparts (P < 0.001). At the macrostructure level, we found that the total score of story grammar elements and the number of story grammars in the narrative production of children with ASD were lower than those in both CAM and LM children (P < 0.001).

The present study, thus, showed that creating a coherent narrative could be more demanding for children with ASD than productivity and syntactic complexity.

Recently, obesity witnessed a dramatic increase and its related comorbidities have grown. Bariatric surgeries were developed to reduce weight. However, all techniques had their advantages and shortages. In this work, we aimed to assess our new modification of combining sleeve gastrectomy with Roux en-y bypass for the management of obesity, hoping to gain benefits from both techniques to increase the excess bodyweight loss (EBW%).

The study was a prospective observational study on 23 Morbidly obese patients. The study was held from January 2020 to April 2022. The recruited patients were submitted to detailed clinical assessment and investigations to check fitness for surgery. Besides operative data, any intra- or post-operative complications were recorded. Each patient was followed up for at least one year. The followup visits were scheduled at regular intervals (one week, one month, six months, and twelve months).

The mean operative time was 113.91 minutes (65-150). No intraoperative complications or conversion. There was intraluminal bleeding in one patient within 48 hours postoperatively with successful conservative management. There was a complete cure of diabetes mellitus (DM) for 5, 2, and 3 patients and antidiabetic drugs were reduced for 64.3%, 21.43%, and 7.14% at 1, 6, and 12 months follow up respectively. Hypertension was cured in 1,1,2 patients, and antihypertensives were reduced for 2,1,1 patient, at 1, 6, and 12 months follow up respectively. EWL% was 14.4%, 40.78%, and 73.74% at 1,6,12 months follow up respectively. Hemoglobin concentration and ionized calcium improved over time. Finally, serum albumin at 1, 6, and 12 months follow-up was 3.64, 3.58, 3.78 g/dL respectively.

New modifications of combining LSG and LRYGB have shown to be safe and effective procedures. In addition, it is associated with minimal postoperative nutritional complications and permits complete visualization of the biliary system using endoscopy.

Verification bias is a common bias in the diagnostic accuracy of diagnostic tests and occurs when a number of individuals do not perform the gold standard test. In this study, we review the correcting methods of verification bias.

In a cross-sectional study in 2020, 567 infertile women who were referred to Royan Research Institute were evaluated. The ultrasound is the performed test and the gold standard are hysteroscopy for some, and pathology for other abnormalities. For correcting verification bias conventional, Begg and Greens, Zhou, and logistic regression methods were used.

In the gold standard hysteroscopy test, the sensitivity (SEN) and specificity (SPEC) obtained in conventional, Begg and Greens, Zhou, and logistics Regression methods were (50%, 90.3%), (48%, 96%), (22%, 77%), (50%, 90%), and (72.8, 77) respectively. Furthermore, the area under the curve (AUC) index and kappa statistics were calculated as 70.2%, and 43.6% respectively. In the pathology gold standard test, the SEN and SPEC for the conventional methods, Begg and Greens, Zhou and logistics regression were (67.7%, 86.7%), (66%, 88%), (29%, 70%), (66.9%, 87.6%), and (73%, 83.9%) respectively. Also, the AUC index and kappa statistics were 77%, and 55% respectively.

In the study on endometrial abnormalities in infertile women, assuming that the missing data mechanism is random, the amount of bias in calculating SEN and SPEC is very low in the diagnostic tests calculated before and after correction, using Begg and Greens and logistic regression method. But Zhou's method gives rather large biased estimates.

Amyloid-beta (Aβ) production is a normal physiological process, and an imbalance in Aβ production/excretion rate is the basis of the plaque load increase in AD. LRP1 is involved in both central clearance of Aβ from the CNS and transport of Aβ toward peripheral organs. In this study, the effect of silymarin combination compared to rosuvastatin and placebo on neuro-metabolites and serum levels of LRP1 and Aβ1-42 proteins and oxidative stress enzymes and lipid and cognitive tests of Iranian AD patients.

In this double-blind placebo-controlled study, thirty-six mild AD patients were divided into groups (n=12) of silymarin 140mg, placebo, and rosuvastatin 10mg. Medications were administered 3 times a day for 6 months. Clinical tests, lipid profile (TG, HDL, TC, and LDL), Aβ1-42, and LRP1 markers were measured at the beginning and end of the intervention. Magnetic resonance spectroscopy (MRS) was used to measure metabolites. Using SPSS software a one-way ANOVA test was used to compare the means of the quantitative variables and Pearson and Spearman's correlations to measure the correlation. GraphPad Prism software was used for drawing graphs. P < 0.05 was considered a significant.

The levels of LRP1 and Aβ1-42 in the silymarin group were significantly increased compared to the other groups (P < 0.05). NAA/mI in the silymarin group had a significant increase compared to both placebo and rosuvastatin groups (P < 0.05). Right and left hippocampal mI/Cr directly correlated with TG (r = 0.603, P = 0.003 and r = 0.595, P = 0.004, respectively). NAA/Cr of the right and left hippocampus was inversely related to TG (r = -0.511, P = 0.0033, and r = -0.532, P = 0.0021, respectively). NAA/Cr and NAA/mI of bilateral hippocampi directly correlated with HDL (P < 0.05). An inverse correlation was observed between the Aβ1-42 and mI/Cr of the right and left hippocampus (r = -0.661, P = 0.000 and r = -0.638, P = 0.000, respectively).

Donepezil and silymarin improved lipid profile associated with increased NAA/Cr, and decreased mI/Cr, in AD patients. Biomarker NAA/mI can be clinically significant in examining AD pathology. Measurement of the lipid factors and neurometabolites can be a suitable method for monitoring this disease.

Nurses’ and physicians’ collaboration is a precedent for patient care. This study examined attitude change and interprofessional collaboration competencies among medical and nursing students of Iran University of Medical Sciences.

This study was quantitative cross-sectional. The study tools were two questionnaires, Attitudes Toward Interprofessional Education and IPEC Interprofessional Collaborative Competencies, which were completed by 211 medical and nursing students in online or in-person forms. The collected quantitative data were analyzed by SPSS 19 software.

The results showed that nurses and physicians constituted 35.5% and 64.5% of the sample. The results of the independent T-test displayed no statistically significant difference in the mean age of both groups (P = 0.054). There was a statistically significant difference in the participants’ attitudes toward interprofessional learning, and the medical group (46.68) obtained a higher mean score than the nurse group (34.92) (P = 0.001). The two groups with varying mean scores (179.34 for medical students and 131.72 for nursing students) were significantly different in their interpersonal collaboration competencies (P = 0.001). Considering Mauchly’s test, there were statistically significant differences among medical students of varying academic years in their attitudes toward interprofessional education (P < 0.001). Nursing students were also different in their attitudes toward interprofessional education based on their academic years.

The results of this study showed that the attitude of nursing students towards interprofessional education and interpersonal collaboration competencies should be increased in line with medical students in order to improve the quality of medical and health services.

Parkinson's disease (PD) is known as the second most destructive central nervous system (CNS) disorder, which leads to movement slowness, tremors, decreased balance, instability, and CNS disorders in affected patients. This study aimed to investigate the effect of 12 weeks of Cawthorne-Cooksey exercises on the balance and the quality of life in patients with PD.

This was a quasi-experimental study, and the research population consisted of PD patients in Zahedan City who were present at the Zahedan Elderly Center during May, June, and July 2022. Twenty-four individuals who were 53 to 69 years old volunteered to participate in this study and were assigned to the experimental (N = 12) and control (N = 12) groups. In addition to the usual treatment, the experimental group performed Cawthorne-Cooksey exercises (CCE) exercises for 12 weeks, while the control group only received the usual treatment during this period. The CCE exercises were performed for 60-minute sessions, three days a week, for twelve weeks. The Berg Balance Scale (BBS) was used to evaluate balance, and the Parkinson's Disease Quality of Life Questionnaire (PDQL 37) was used to assess the QOL of PD. The data were analyzed using Wilcoxon and Mann-Whitney U tests.

The Mann-Whitney U test results revealed that the experimental group exhibited significantly higher scores in all factors of QOL and balance during the post-test when compared to the control group (P < 0.05). Moreover, the outcomes of the Wilcoxon test demonstrated significant improvements in all components of QOL and balance for the experimental group from pre-test to post-test (P < 0.05), whereas the control group experienced a notable decline in both balance and QOL during the same period (P < 0.05).

The study demonstrates that CCE exercises positively influence the balance and quality of life of Parkinson's disease patients, suggesting their potential as complementary therapy in the treatment of PD.

The menopause stage in women reduces estrogen levels and bone indicators. This study compared the effects of highintensity resistance training (HIRT) and low-intensity resistance training (LIRT) on bone mineral density (BMD) and bone mineral content (BMC), T-score, and Z-score in postmenopausal women with osteopenia.

A randomized controlled trial was conducted among 45 postmenopausal women, aged 50 to 60, who were randomly assigned into 3 parallel groups (n = 15 in each). The exercise program was performed by the interventional groups—the HIRT and LIRT groups—at 4 different intensities, 3 times a week for 24 weeks: 8 repetitions at 80% of 1 repetition maximum and 16 repetitions at 40% of 1 repetition maximum. The evaluated areas (BMD, BMC, T-score, and Z-score) included the lumbar spine (LS) and the femur neck (FN) using a DEXA machine. One-way analysis of covariance and Bonferroni's post hoc tests were used for data analysis.

The results indicated significant differences in BMD, BMC, T-scores, and Z-scores between the means of the LS and the FN in all groups. In addition, significant differences were revealed in the BMC of the LS, the BMD, T-scores (P < 0.001), Z-scores (P = 0.001), and in the BMC of the FN (P < 0.001), the BMD (P = 0.001), T-scores, and Z-scores (P < 0.001), respectively. In addition, the HIRT group's bone indices were considerably greater than those of the LIRT group (P < 0.00). Nonetheless, LIRT was significantly greater than that of the control group (P > 0.00).

According to the current findings, HIRT seems to be the most effective training program compared with LIRT for bone indicators improvement in the femur neck and the lumbar spine among postmenopausal women with osteopenia.

Within the public sector, health managers occupy positions that are typically filled by individuals with a medical, clinical, or nursing experience who are entrusted with assuming an additional role. The primary objective of this study was to employ a scoping review methodology to ascertain a cluster of prevalent subjects encompassing the development of a proficient health care manager.

The purpose of this scoping review study was to identify critical components in the field of management professionalization, as described by Arksey and O'Malley. A total of 13 studies, characterized by predefined keywords, were meticulously culled from Scopus, Web of Science, PubMed, and Embase, Magiran, and SID databases. The inclusion and exclusion criteria considered factors such as language, temporal relevance, redundancy, thematic alignment with the professionalization domain, and congruence with the overarching objectives and methodologies of the present investigation. Subsequently, the contents of the selected studies were subjected to rigorous thematic analysis and judicious categorization using a framework analysis approach.

From a total of 10,117 articles, a rigorous selection process yielded 13 articles to be included in this study. The identified dimensions are classified and elucidated across 6 overarching domains; namely, the science of management, educational trajectory, and curriculum, cultural infrastructure and ideologies, standards, professional institutions and associations, and licenses and certifications.

To enhance the efficacy of health management, policymakers and planners ought to adeptly incorporate these dimensions within the framework of the country's health system.

 Quantitative electroencephalography (EEG) power spectra analysis was applied to assess brain activation during chronic pain. Although many studies have shown that there are some common characteristics among individuals suffering from various pain syndromes, the data remains inconclusive. The present study aimed to assess chronic low back pain (CLBP) based on functional brain changes with EEG in CLBP patients compared with healthy controls.

 Multichannel electroencephalogram data were recorded from 30 subjects with CLBP and 30 healthy controls under eye-open resting state conditions and active lumbar forward flexion, and their cortical oscillations were compared using electrode-level analysis. Data were analyzed using a pair t-test.  

 A total of 30 patients (19 men and 11 women in the case group (mean [SD] age, 35.23 [5.93] years) with 30 age and sex-match healthy controls participated in the study. A paired t-test was applied to identify whether there was any difference in the absolute and relative power of frequency spectra between CLBP patients and healthy controls. The results showed a significant increase in alpha relative power in CLBP patients compared with healthy controls in an open-eye resting state (P < 0.050) and active lumbar forward flexion (P < 0.050). 

 The enhanced alpha relative power in CLBP patients could be relevant to attenuating sensory information gating and excessive integration of pain-related information. Increased power at the EEG seems to be one of the clinical characteristics of individuals with CLBP. EEG can be a simple and objective tool for studying the mechanisms involved in chronic pain and identifying specific characteristics of CLBP patients.

 Coronavirus disease 2019 (COVID-19) has been associated with a hypercoagulopathy state; however, the efficacy of different anticoagulant regimens in preventing thrombotic events is not clear. We aimed to compare therapeutic versus prophylactic enoxaparin therapy in severe COVID-19 patients.

 In this single-center, open-label, randomized controlled trial, adult patients with severe COVID-19 presentations and an increased D-dimer level of more than 4 times the normal upper limit were randomly assigned to receive either prophylactic or therapeutic dose of enoxaparin. All patients were observed for at least 4 months regarding the overall survival as the primary outcome. Hospitalization duration, the need for intensive care unit (ICU) admission, the need for mechanical ventilation, and major adverse events (MAEs) were also analyzed as the secondary outcomes. Survival analysis was done via Kaplan-Meier curves and the Log-rank test. Cox regression was used, adjusting for baseline variables.

 Overall, 237 patients (152 men and 85 women) were randomized to either arm (121 to prophylactic and 116 to therapeutic groups). The mortality rate was 27 (22.3%) and 52 (44.8%) in prophylactic and therapeutic arms, respectively. Prophylactic enoxaparin was associated with better survival in the log-rank test (P < 0.001; HR, 0.42). Additionally, a significantly lower rate of ICU admission, a lower rate of MAEs, and shorter hospitalization were observed in the prophylactic arm (P < 0.001, P = 0.009, and P = 0.028, respectively).

 The results of the current study were in favor of anticoagulant treatment with prophylactic doses of enoxaparin. Still, due to the limitations of this paper, we suggest that these findings be treated cautiously.

 Many elder people have knee osteoarthritis (OA). The patients are faced with pain and disability in movement. Given the challenging lifestyle of the patients, finding an efficient therapy approach is necessary. Since low-level laser therapy applies to the treatment of many diseases, it seems it can be a suitable option for the treatment of knee OA. The present study aimed to evaluate the molecular mechanism of laser therapy on knee OA via a protein expression change study.

 The present study examines the gene expression profile of patients with OA in the knee using bioinformatics. The protein expression change profile of synovial fluid of knee OA patients is extracted from the literature and is analyzed based on the rate of expression and interactions between the differentially expressed proteins (DEPs). The results are compared with the DEPs of similar tissue of the treated knee OA patients (from published documents) after laser therapy.

 Apolipoprotein B (APOB) and matrix metallopeptidase 2 (MMP2) were determined as the hub bottlenecks of the protein-protein interaction (PPI) network of synovial fluid of knee OA patients. MMP2, complement 5, transthyretin, and apolipoprotein A-1 from laser-treated patients were related to the PPI network of knee OA patients. The reduction of Interleukin-6 activity was highlighted as a critical event as a function of laser on the human body.

 In conclusion, it was noted that the main phenomenon associated with laser therapy-induced improvement in the condition of knee OA patients is the downregulation of MMP2. 

 The most challenging risk of mechanical valves is thromboembolic events; therefore, life-long anticoagulation therapy is necessary. Anticoagulation therapy should be adjusted for each patient with serial international normalized ratio (INR) monitoring. Due to the small number of patients with a mechanical valve in the pulmonary position, we are facing a lack of information about the therapeutic range of the INR in these patients. We aimed to evaluate patients with a history of pulmonary valve replacement (PVR) who faced malfunction and compare their INR and echocardiographic data at the time of malfunction and 3 months prior.

 In this cross-sectional study, 71 patients who had previously undergone PVR and presented to Shaheed Rajaie Cardiovascular Medical and Research Center with a diagnosis of pulmonary valve malfunction between 2014 and 2021 were included. Patients' INR and echocardiographic data at the time of the malfunction and 3 months before the malfunction diagnosis were gathered from the hospital's registry. IBM SPSS 20.0 was used for data analysis   

 In this cross-sectional study, 71 patients with mechanical pulmonary valve malfunction were included. 49.3% (n = 35) were men, 50.7% (n=36) were women, and their mean age was 33.23 (±8.279). The mean INR of all patients 3 months before malfunction and at the time of malfunction was 2.29 (±0.753) and 2.20 (±0.704), respectively.

 In this study, most of our patients had an INR below the therapeutic range, both at the time of malfunction and 3 months prior. It emphasizes the importance of patient follow-up and keeping the INR in the therapeutic range.

Improper use of antibiotics is one of health care problems that can lead to side effects or antibiotic resistance without benefit. This study aimed to evaluate the association between health literacy and knowledge on appropriate use of antibiotics in a population sample from Tehran.

This was a cross-sectional, descriptive-analytic study on adults aged between 18 and 65 years. Health literacy was measured by the Health literacy for Iranian Adults (HELIA: Health Literacy for Iranian Adults) questionnaire, and awareness about proper antibiotic use was evaluated by a checklist designed based on a literature review and expert’s opinion in domains of knowledge and attitude. Both an online Google Forms questionnaire and a paper questionnaire completed by outpatients from particular clinics in Tehran's north, west, or center were used to collect the data. SPSS Version 22 was used to analyze the data.

Out of 359 participants, 59.6% were women, and 66.8% had a university education level. Internet and health care workers were the main sources of health information. The mean score of health literacy was 71.4 out of 100, and 67.4% of the respondents had excellent or sufficient health literacy. The mean antibiotic awareness score was 10.5 out of 13, and the score in the domain of attitude was higher than knowledge. There was a significant relationship between health literacy and awareness about proper antibiotic use (P < 0.001). Health literacy was significantly higher in women (P = 0.001), people with higher education levels (P = 0.001), and financial sufficiency (P = 0.0038). Also, there was a significant relationship between awareness about proper antibiotic usage and age (P = 0.007) and financial sufficiency (P < 0.001) of the respondents. The online questionnaire users were not different in terms of their health literacy, but they were more educated and aware of antibiotics.

The level of health literacy and awareness about the proper use of antibiotics in this study was good. level of health literacy was closely related to knowledge about the proper use of antibiotics, thus, it seems that promoting health literacy may increase awareness about proper antibiotic use.

 The study of various aspects of information behavior has attracted the attention of many researchers. This study used the structural equation modeling method to identify factors affecting respondents’ strategies in answering health-related questions on social question answering (SQA) websites.

 The study population in this quantitative-applied survey included all respondents answering health-related questions on national and international SQA websites, among whom 431 individuals were selected as the sample using SPSS SAMPLE POWER software and convenience sampling. The data were collected using the Respondents’ Motivations and Strategies Questionnaire and the Social Support Questionnaire. The items of these questionnaires are scored on a 5-point Likert scale. The conceptual research model was evaluated using the structural equation modeling method, and the collected data were analyzed in SPSS 26.0 and AMOS 24.0.

 The authors identified and analyzed the factors influencing respondents' strategies and the relationships between these factors. Motivations, social support, sex, age, income, level of education, amount of activity per week, and response time are effective on response strategies with factor loadings of 0.61, 0.56, 0.50, 0.53, 0.31, 0.66, 0.53, and 0.65, respectively. The variable determination coefficient of response strategies in the structural equation model is reported to be 0.55 and significant. Finally, response strategies can be predicted based on the independent variables.

 In order to enhance response strategies, it is important to promote effective response behaviors, as determined by the components that influence response strategies. The quality of related online services, such as expert question-answering and digital reference services, can be improved with the help of the present findings.

 Bibliometric analysis may indicate the most active specialist, authors, and journals in a given research field. To the authors' knowledge, there is no bibliometric analysis to provide a macroscopic overview in the field of secondhand smoke that harms non-smoker. 

 Using the bibliometric method, 644 articles that were present in the Scopus database between 1973-2020 on the subject were considered. The data were analyzed by two visualization and science-mapping software called Bibliometrix and VoS Viewer. Also, reference publication year stereoscopy and Co-Citation historiography were used. In the qualitative analysis, 52 articles were selected that had the most citation and were analyzed.

 In this paper, the findings show that the documents were published in 364 sources with an average citation per document of 25.14 and more than 3 authors or nearly 4 authors per document. The peak reference publication year stereoscopy happened in the year 199 with 974 references. The countries with the highest number of MCP were the USA, China, and Spain. The “International Journal of Environmental Research” and “Public Health”, has raised their publications in the field of secondhand smoke and pregnancy rapidly since 2003. Among the titles, "passive smoking" was the most used.

 The study highlights the importance of understanding the harmful effects of secondhand smoke on the developing fetus. The findings also shed light on key research trends, influential authors, and active research areas, which can guide future studies and support evidence-based decision-making in the field of maternal and child health.

 HIV/AIDS-related stigma and discrimination are among the main barriers to controlling the HIV epidemic. Discriminatory behavior in healthcare settings deprives people of accessing high-quality health services.

 This study presents the design, development, and pilot study of a novel web-based application (“REDXIR”), which is designed based on behavioral and gamification principles and aims to eliminate HIV/AIDS-related discriminatory behavior among health professions students. REDXIR storyline is set in an imaginary world where the students' journey is like a 10-level game, in which each level consists of several missions with a certain amount of score. The participants have to accomplish the mission to reach the minimum amount of score to pass each level. Finally, each becomes an individual who has not only the knowledge but also the competency to educate and advocate appropriately in the field.

 The pilot was done in six medical sciences universities in Tehran, Iran. The feasibility of the instructional design, specifically gamification strategies in the field of HIV education, and the executive functions to run the program on a bigger scale were evaluated. In total, 241 students were included and performed 1952 missions. The program evaluation showed a mean satisfaction score of 4.16 (from 1, the lowest, to 5, the highest) and participants considered their learning practical and gamification method appropriate for HIV education.

 A meaningful gamification design for an online medical education program could be a suitable, functional, and applicable learning model to reduce HIV/AIDS stigma and discrimination among health professions students.

Scenarios are the most efficient methods to explore our uncertainty about the future. Even with increasing utilization, the majority of scenarios still fall short of meeting the future “uncertainties” in health. This article examines one of the most sensitive encounters of the health system with uncertainties—COVID-19 pandemic—and the type of uncertainty analysis in health scenarios to discuss the importance and determine the existing gaps while providing a better mechanism for scenario planning in the health system.

To examine the extent, range, and nature of scenario research, a preliminary mapping of the existing literature, summarizing research findings, and identifying research gaps, we have taken help from the Arksey and O'Malley (2005) model and to improve the quality of the results, we have also used the PRISMA framework. To identify the studies relevant to the issue, the PubMed and Embase databases were searched for peer-reviewed published articles. All peer reviewed articles from January 01, 2020, to December 31, 2020, were included in this review. The search strategy was mainly the systematic use of English keywords such as “coronavirus,” “covid-19,” “SARS-CoV-2,” “2019-ncov,” and scenario. To improve the search sensitivity, subject searching based on MeSh and Emtree keywords was used.

It is crucial to identify the health domains where the scenarios can be used. The major ideas that were covered and their variations would also be identified using these different scenarios. Based on the selected articles, we can answer some critical questions. First, in which health fields is the scenario method used? Second, what are the key concepts in these studies, and third, what is the difference between them? Policy, epidemiology, and economics use futures studies scenarios more than other social science disciplines in health. Furthermore, we have looked at the fact that selecting the appropriate kind, utilizing new methodologies, and emphasizing uncertainty analysis are the core difficulties associated with health case scenarios.

Based on examining the existing indicators in the health scenarios, establishing the “uncertainty analysis” as the basis can improve scenario planning in this field. Also, if scenario planning is done as a process based on uncertainty analysis, it is more accurate and helps make better decisions in the field of health.

 The identification of the determinants of health literacy is an essential prerequisite for developing health literacy promotion programs. While these factors have been reported in previous studies, there is a lack of a comprehensive review specifically focused on the Iranian population. Therefore, this review aimed to identify the factors related to health literacy in Iran.   

 This scoping review used the Arksey and O'Malley methodological framework and the Joanna Briggs Institute framework. A search was performed in English-language databases—Web of Science, Scopus, and PubMed—using the MeSH keyword of "health literacy," and in Persian-language databases—Magirean and SID—using the related keywords. A narrative synthesis was conducted to describe all included studies' characteristics and explore factors associated with health literacy.

 A total of 76 studies were included. Based on the results of the study, related factors included personal factors—including sex, age, education level, field of study, parents’ education level, marital status, occupation, work experience, employment status, ethnicity, income, socioeconomic status, medical history, duration of disease, addiction, number of children, media literacy, information literacy, computer literacy, and self-efficacy—situational factors—including use of the internet, use of social networks, social support, source of information, and participation in health education classes—and societal and environmental factors—including place of residence and type of insurance.

 Modifiable factors identified in this study were self-efficacy, social support, information sources, media literacy, information literacy, computer literacy, internet or social networks, and participation in health education classes. Planners can consider these factors when developing interventions to promote health literacy.

 Laptops are ubiquitous tools in today's society; however, their prolonged use often leads to discomfort and musculoskeletal disorders due to their nonergonomic design. This study aimed to evaluate the effectiveness of an innovative adjustable laptop stand in enhancing comfort and productivity during typing tasks.

 A 2-phase experimental design was employed. Phase 1 involved the development of a novel laptop stand considering ergonomic principles and expert recommendations. In Phase 2, a total of 25 office workers—13 men and 12 women—participated in 3 randomized sessions of a 2-hour typing task. They used the newly designed stand, adjusted their laptop height using conventional methods, or completed the task without any height adjustment (control). The Local Subjective Discomfort Questionnaire (LPD), the Rapid Upper Limb Assessment (RULA), and speed and error rates were used to measure postural risk, subjective discomfort, and typing performance, respectively, during each session. SPSS Version 26 (IBM) was used for the analysis, and P ˂ 0.05 was considered statistically significant.

 The RULA scores were significantly lower with the newly designed stand compared with the other conditions. When using the stand, perceived discomfort in specific regions significantly decreased (P < 0.05). Moreover, the number of typing errors significantly reduced with the stand (P < 0.05), while no significant difference was observed in typing speed (P = 0.371).

 The novel adjustable laptop stand significantly reduced discomfort and improved typing accuracy during typing tasks, suggesting its potential to enhance user comfort and productivity. However, further longitudinal studies are needed to assess the long-term effects of this intervention.

 Gene therapy holds immense potential in the field of wound healing. However, we still do not recognize this procedure well enough to give oversight effectively to improve healing processes. A wide range of information has been achieved from the database for gene expression profiling by clinical trials, So we performed this study to gain a better understanding of the mechanisms behind wound healing and how it could be utilized to develop new therapies and treatments.

 In this study, we have been focusing on wound-healing genes, conducting a thorough review to explore the various genes and pathways involved in this process. For this purpose, a total of 320 articles were collected. All experimental studies, systematic or narrative reviews, studies and clinical trials included in this paper were searched on PubMed, Medline, Embase, Science Direct, and Scopus databases in English using the following terms: Wound Healing, wound regeneration, Gene Transfer, and Gene Therapy were used to search the mentioned databases. Unfortunately, we didn’t find a large sample cohort study on this topic. A total amount of 330 articles were collected based on the guidelines of the PRISMA method. Both inclusion and exclusion criteria were settled.

 During the last decade, different models of gene delivery have been introduced, which include viral transfection and Non-viral techniques. In this regard, TIMP-2 protein and VEGF mutants such as VEGF165, CARP, and HIF-1 are the genes that accelerate the rate of tissue repair.

 The process of wound healing is mainly related to the change of expression of genes that have a role in the parts of inflammation and repair. In our study, some of the most suitable genes involved in the wound-healing process are mentioned.
