Given that no study has so far carefully examined the effects and benefits of crystalloids on the hemodynamic status and events during the surgery for lower limb orthopedic surgeries, the current study aimed to compare fluid therapy with normal saline (NS), Ringer (R), and Ringer’s lactate (RL) during anesthesia on the hemodynamic status and events during lower limb elective orthopedic surgeries.

This cross-sectional descriptive study was conducted in 2019 with the participation of 270 patients (three groups each including 90 subjects) who were scheduled for an elective lower limb orthopedic surgery in Imam Reza hospital of Tabriz. Patients received one of these serums of NS, R, and RL. Electrolytes were measured before and after the surgery. Finally, data were analyzed using ANOVA and chi-square tests.

Based on the results, there was no significant difference between the three groups in terms of hemoglobin, hematocrit, sodium, calcium, potassium, chlorine, albumin, creatinine, urea, bicarbonate, pH, and arterial oxygen levels (P>0.05), and RL serum had the least effect on all factors.

In general, the administration of NS, R, and RL in lower limb orthopedic surgeries did not result in significant differences although RL had the least adverse effects and was associated with better results.

Due to the high prevalence of osteoporosis in Iran and its relationship with bone fractures and reduced life expectancy in these patients and the knowledge that early diagnosis and timely treatment reduces the financial burden on the treatment system and the burden of disease complications on patients. Density of one-third distal radius was performed in patients prone to primary osteoporosis.This descriptive cross-sectional study was performed during 2019 with the participation of 71 patients referred to orthopedic clinics of Tabriz University of Medical Sciences. Clinical examinations and bone density measurements were performed for them and its relationship with distal third radius fractures was investigated. Data were analyzed using Pearson correlation test. Sensitivity of one-third of the distal radius T-score compared to femoral neck T-score in terms of diagnosis of osteoporosis and osteopenia 82.35 and 51%, respectively, and its specificity 46.51%, and for total lumbar vertebrae in terms of diagnosis of osteoporosis and osteopenia, respectively. 92.31% and 65.62% and its specificity was 30.77%. According to the findings of this study, the study of one distal one-third mineral density of radius bone by DXA method for the diagnosis of osteoporosis has a significant sensitivity and has a significant relationship with the density of lumbar vertebrae (femur).

Many factors such as stress and psychological tension affect the mental and physical health of pregnant women in the third trimester during the coronavirus pandemic. These factors can cause severe complications such as sleep disorders and low back pain. Therefore, this study focused on investigating sleep disorders in women by diagnosing low back pain in pregnant women with coronavirus and the affecting factors.

This descriptive-analytical study was performed during the four months ending July 5, 2020 with the participation of 40 pregnant women (with coronavirus disease detected in the last trimester of pregnancy) with a diagnosis of low back pain in Tabriz (Iran) using a random sampling technique. Demographic data, anxiety and depression, Petersburg’s sleep quality, factors affecting sleep quality, and the severity of back pain (visual analog scale) were electronically collected and analyzed using SPSS 20 by ANOVA and multivariate regression.

All participants were at a weak level. The majority of participants had a score of “serious sleep problem”, and nausea and vomiting (P=0.041), low back pain (P=0.003), frequent urination (P=0.011), leg cramps (P=0.031), and constipation (P=0.018) caused severe sleep disturbance in pregnant women during coronavirus pandemic.

In general, having coronavirus disease causes severe pain in pregnant women, leading to severe back pain in pregnancy, eventually worsening sleep disorders.

Many studies have investigated the effects of Kinesio tape on the symptoms of carpal tunnel syndrome (CTS). The present study aimed to review the results of clinical trials on the use of Kinesio tape to improve CTS symptoms. The present systematic review was based on PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) on clinical trials. The keywords “Carpal Tunnel Syndrome, Median Nerve, Kinesio Tape, and Physical Therapy” were searched in Embase, PubMed, SID, Magiran, Cochrane Library, Scopus, ScienceDirect, Springer, Ovid, ProQuest, PEDro, and Google Scholar databases. Out of 1259 articles, only 13 met the requirement for inclusion in the study. The results of 11 articles indicated that the use of Kinesio tape could significantly reduce CTS symptoms. The use of Kinesio tape reduces CTS symptoms (ie, pain, numbness, and hand function).

Knee and hip replacement surgeries are associated with chronic postoperative pain, and since their management is a clinical challenge to nurses.

The present meta-analysis aimed at investigating preoperative education for pain relief after the lower limb joint replacement surgery.

Quasi-experimental studies and clinical trials of preoperative education for the management of pain after hip and knee replacement surgeries published in English were searched in the databases of Web of Science, Cochrane Library, CINAHL, PubMed, Embase, and Scopus.

Out of 209 articles retrieved, five were eligible to enter the meta-analysis. Based on the obtained results, the difference in the mean scores of pain on days 1, 2, and 3 after surgery in the intervention groups was lower than that of the control groups; however, the relationship was statistically insignificant.

Evidence from study results suggests that pre-THA and Total knee arthroplasty (TKA) training may not significantly reduce pain; However further studies are required.

Failure to diagnose some injuries in patients with multiple trauma referring to the emergency room can lead to problems and disabilities. Thus, it is necessary to be aware of these cases. In this respect, this study was conducted to investigate undiagnosed injuries in patients with multiple trauma who referred to the Northwest Emergency Center of Iran.

This descriptive-analytical study was conducted in Imam Reza hospital in Tabriz with the participation of 1000 patients by random sampling during 2019. Demographic data and data related to trauma (during hospitalization and after discharge) were obtained from patients’ medical records. Finally, data were analyzed in SPSS (version 20) using χ2 and logistic regression tests.

The type of the accident was significantly associated with damage to the central nervous system (CNS) and the musculoskeletal system (P=0.001 and P=0.003, respectively). Based on the evaluation of patients who came for examination for the second time, it was observed that 22.4% of cases with injuries were not diagnosed during hospitalization. Motorcycle and pedestrian accidents were significantly associated with failure to diagnose in the hospital, and age, motor accident, and winter variables were significantly contributed to the lack of diagnosis.

Orthopedic injuries (upper limbs are much more common than lower limbs) are the most common injuries that are not diagnosed in hospitalized patients with multiple trauma. These injuries are more prevalent among individuals aged 5-30 years old who have been involved in car accidents in the winter.

Free muscle transfer in Volkmann’s contracture surgery is the most difficult method for achieving good results. The aim of the present study was to evaluate the outcomes of tendon bypass transfer to finger flexors by tensor fascia lata graft in patients with Volkmann’s contracture.

This non-randomized clinical trial was conducted on 15 patients (based on a relevant study, census sampling) during 2015-2019 in Shohada hospital, Tabriz. The patients underwent surgery in two stages. In the first stage, muscle release and nerve neurolysis were performed, and in the second stage, the tendon was prepared and connected to the bypass in the volar forearm at the proximal and to finger flexors at the distal joint. Hand grip strength, finger and wrist range of motion, hand dexterity, and daily activities were assessed using the considered tools, and finally, the data were compared using SPSS 20. P<0.05 was considered statistically significant.

The preoperative status of the subjects regarding the studied variables was extremely unfavorable, however, hand grip strength (81.35±10.18), Fugl-Meyer (29.49±05.25), hand dexterity (08.59±01.83), and daily activities (81.10±07.43) showed a highly favorable and significant improvement after the surgery (P=0.001).

The tendon bypass transfer to finger flexors by tensor fascia lata graft in patients with ischemic Volkmann’s contracture resulted in acceptable improvements after the surgery.

Probiotics may have a role in preventing ventilator-associated pneumonia (VAP) by inhibiting the natural flora from transforming into pathogenic flora. Therefore, this study aimed to investigate the effects of probiotics on the prevalence of VAP in multitrauma patients hospitalized in a neurosurgical intensive care unit (ICU). This randomized clinical trial was performed between 2018 and 2019 with the participation of 150 patients hospitalized in theNeurosurgical ICU. After randomizing the participants (using the permutable blocking method) into the intervention (probiotic) and control (placebo) groups, the interventions were implemented. The participants received one capsule every 12 hours by gavage and their VAP symptoms were evaluated and recorded. Data were inputted into SPSS22 and then compared using the chi-square, independent t-test, Fisher's exact tests, and repeated measures ANOVA. The prevalence of VAP was significantly lower in the intervention group than the control group (p=0.001). A significant difference was observed between the two groups in pH (p=0.029) and WBC (p=0.042). The between-group difference was not significant in other variables. Probiotics are effective in reducing the prevalence of VAP in trauma patients hospitalized in ICU.

Pregnancy is one of the pleasant periods of a woman’s life that turns into a bitter experience by common complications such as low back pain (LBP). Due to prevailing climatic conditions in Iran and the harmful social norms concerning Iranian women, the present study aimed to investigate the prevalence of pregnancy-related LBP and its influencing factors during different months of pregnancy.

This descriptive cross-sectional study was conducted in 2019 on 550 pregnant women for LBP who were eligible based on the inclusion criteria. The research instruments were a demographic questionnaire, a LBP examination, and the visual analog scale (VAS). The obtained data were analyzed using the chi-square test, the independent t test, and multiple logistic regression in SPSS 20, and a P<0.05 was considered statistically significant.

The prevalence of LBP was 67.27%, and the most important factors influencing pregnancy-related LBP were maternal age (OR=950, P<0.008), gestational age (OR=1.023, P=0.015), body mass index (OR=802, P=0.045), duration of sitting (OR=1.812, P=0.036), and the duration of standing (OR=1.625, P=0.042).

Overall, there was a high prevalence of pregnancy-related LBP in primiparous women in the present study and its predisposing risk factors included advanced maternal age, obesity, and low level of ability to sit and stand for a long time.

Given the high prevalence of low back pain in pregnancy and the increase in pain intensity in women with a history of low back pain in previous pregnancies and the recommendation of not to use analgesics in pregnancy, this study was performed with aim to investigate the effect of four weeks of physical exercise in water on the severity of low back pain in pregnant women with previous history of pregnancy low back pain.

This randomized controlled clinical trial study was conducted with participation of 80 pregnant women with pregnancy low back pain and previous history of pregnancy low back pain at Tabriz University of Medical Sciences in 2019. In addition to lifestyle modification, the intervention group performed stretching and strengthening exercises for 16 session of 1 hour in the water, and the control group was only encouraged to improve their lifestyle. The Qubak questionnaire and demographic information were used before and after the intervention for all participants. Data was analyzed by SPSS software (version 20) and Clomogrov-Smirnov and dependent T-test. P <0.05 was considered statistically significant.

At the end of the intervention, the intensity of pain in the intervention group (23.45±03.56) was significantly lower than the control group (77.15±13.03) (P=0.001); on the other hand, in the intervention group, the intensity of pain at the end of the study (23.45±03.56) was significantly reduced compared to the beginning of the study (73.19±11.42) (P=0.001). While in the control group, no significant changes occur after the intervention (77.15±13.03) compared to before it (74.36±12.23) (P=0.419).

Four weeks of physical exercise in the water could reduce the severity of low back pain in pregnant women with a history of low back pain; these movements are recommended for pregnant women.

Ice cream frozen mixture of milk composition، materials، sweeteners، stabilizers، emulsifiers and flavor is produced. Ice cream is a combined food with a variety of colloidal features due to the structure of the various components، such as ice crystals and dispersed air cells in serum phase. In this study sensory evaluation of ice-cream was studied by using different ratios of sucralose as a substitute of sugar in the ice cream. Vanilla ice cream with 19% sugar was used as a control sample and sucralose in five levels (20، 40، 60، 80 and 100%) was substituted for sugar in the formulation. Then sensory evaluations were investigated. During the Results showed that in this study، there was no significant difference in samples (p<0/05). Sensory properties by judges taste was used five-point hedonic scale. But only 20% substitution level had a significant effect on the properties of texture، mouth feel and overall acceptability.
