Nurses working in Covid-19 wards suffer from a variety of physical and psychological complications that require attention.  this study aimed to compare of demoralization in nurses of COVID-19 wards and other wards admitted to hospitals affiliated to Alborz University of Medical Sciences in 2021.

The present study is a descriptive-analytical study and its statistical population is all nurses working in Covid-19 wards and other wards of Shahid Madani and Imam Ali (AS) hospitals in Karaj affiliated to Alborz University of Medical Sciences in the second half of the 2021. 200 nurses were selected and examined through simple random sampling method based on inclusion criteria. Nurses' demographic characteristics questionnaire and 16-item questionnaire Kissane-II demoralization were used to collect data. Data were analyzed with SPSS version 21 software and using statistical tests.

Most of the nurses participating in the study were married, with undergraduate degrees, rotation shift workers with contract employment status who had Covid-19 disease at least once. The mean score of demoralization of nurses working in Covid-19 and other wards were (22.50±2.73) and (17.15 ±3.22), respectively, and were severe. There was a significant difference between the mean scores of nurses' demoralization syndrome (P <0.001), meaning and purpose subscale (P <0.001) and anxiety and coping subscale (P <0.001) and in three cases, the mean scores of nurses working in Covid-19 wards were higher.

It is very important to pay attention to the psychological issues and complications resulting from caring for patients during the Covid-19 pandemic, and it is necessary to take effective management measures to control them. Also, because the demoralization in nurses working in Covid-19 wards was higher than nurses in other words, it is recommended that all nurses, especially front-line nurses, be given more importance and value during the crisis.

A high-performance Ni, Co-MOF-G/nickel foam was fabricated using a novel electrodeposition method and used as an electrode material for a supercapacitor application. Structural tests including powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and Raman results affirmed the formation of the electrode active materials. Scanning electron microscopy (SEM) images showed a flower-like Ni, Co-MOF inside graphene sheets forming a composition of active materials on the nickel foam substrate. The electrochemical performance of the Ni, Co-MOF-G/ Nickel foam was examined using cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS). The prepared electrode delivered approvable specific capacitance of 1158 F g-1 at the current density of 2 A g-1 in three molar potassium hydroxides. Excellent storage capacity of the fabricated electrode is attributed to the synergetic effects of bi-metal metal organic frameworks (Ni, Co-MOF) with porous carbon materials (graphene).

More than half of all sudden cardiac arrest cases occur out of hospital, and cardiopulmonary resuscitation (CPR) is the responsibility of emergency medical personnel in these cases. Therefore, it is essential for them to have the knowledge and competence to perform the resuscitation. This study aims to determine the effect of CPR education on the knowledge and performance of Emergency Medical Services (EMS) personnel.                                                                    Methods and Materials: 

In this quasi-experimental study, 46 emergency medical personnel who were selected through optimum allocation of stratified random sampling were studied to assess their knowledge and performance before and 14 days after the education. The training was implemented in groups (6 hours of theory and 6 hours of practical training on moulage). At the end of the first session, the pamphlets were provided to all subjects. The data collection tools included a researcher-made questionnaire on demographics as well as 20 questions to assess knowledge, and a 31-item checklist for observing CPR performance. Face as well as content validities were assessed, and test-retest as well as interrater methods were used for reliability of the tools.

The mean and standard deviation of knowledge scores were 13.06±2.37 as well as 18.19±1.55 and performance scores 20.04±2.8 as well as 28.63±2.8 before and after the intervention respectively, indicating the positive effects of education on knowledge and performance (p <0.001).                                              

The CPR education had significant effects on improving knowledge and performance of the subjects. Thus, it seems necessary to hold updated courses on CPR and allocate more time for practical training in teams.

Patent ductus arteriosus (PDA) is a common condition in premature babies, with a prevalence rate of 30 - 60%, and often requires medical or surgical intervention.

This study aimed to assess the effectiveness of 2 different brands of ibuprofen in PDA closure in preterm infants weighing less than 1500 g.

This single-blind clinical trial study was performed on 75 premature neonates with PDA in the pediatric ward of Vali-Asr Hospital in Birjand from March 2014 to March 2019. Patients were treated with two brands of ibuprofen at doses of 10 mg/kg for the first day and 5 mg/kg for the second and third days (24 and 48 hours afterward). Before and three days after the last dose, the children were examined by pediatric cardiologist echocardiography. The data were input into SPSS version 23 and analyzed using descriptive statistics, such as mean and SD. Inferential statistics, such as the chi-square test, were also employed with a significance level of P-value < 0.05.

There was a significant difference between the rate of PDA closure, 78.8% in the Pedea group vs. 54.8% in the Ibuprofen group (P = 0.03). In the Ibuprofen group, there was no difference in drug efficacy in PDA closure between male and female neonates (P = 0.663). Also, in the Pedea group, there was a significant difference in terms of efficacy between male and female neonates (P = 0.049). No significant difference was observed in PDA closure between the two medications based on their sizes (P = 0.616 in small size, P = 0.266 in medium size, and P = 0.175 in large size).

Pedea is more effective than Ibuprofen. It reduces complications and the need for surgery. However, there was no significant relationship between the two drugs based on the PDA sizes. Therefore, it seems logical to use the Iranian brand of ibuprofen, considering the benefits equal to the foreign one.

One of the important nursing interventions in intensive care unit is tracheal suctioning to drain airway secretions. Although this procedure is necessary and useful for managing patients' airways, it is sometimes painful and causes mucosal injury, so it is necessary to try to find tools or methods with the least injury. The purpose of this study was to determin and compare pain and mucosal injury in tracheal suctioning with foley and nelaton catheters in patients admitted to the intensive care unit of selected hospitals affiliated with Alborz University of medical sciences in 2022. 

The current study was a two-group experimental study, and its statistical population was all patients hospitalized in the intensive care unit of Alborz Karaj Hospital in the first half of 2022. Based on the inclusion criteria, 60 patients were selected through the available sampling method and randomly assigned to two groups: suction with Foley catheters and suction with Nelaton catheters. Patients were suctioned for three days or 12 times as needed and were compared in terms of pain intensity and the amount of mucosal damage caused by suction. In order to collect data, the demographic information form of the patients, Behavioral Pain Scale (BPS) and the observational checklist of mucosal injury were used to evaluate the mucosal damage. The data were analyzed with SPSS21 statistical software and using Independent t-tests, Fisher's exact and chi-square tests. 

There was no statistically significant difference between the two groups in terms of demographic variables. Before suctioning, there was no statistically significant difference between the pain intensity of the two groups of patients at any of the 12 times (P>0.05). But after suction, this difference in the first (P=0.005), second (P=0.003), third (P=0.011), fifth (P=0.017), sixth (P = 0.016), the seventh (P = 0.006), the eighth (P = 0.003), the ninth (P = 0.017) and the tenth (P = 0.017) were significant and suction with Foley catheter compared to Nelaton catheter had less pain (P<0.05). In the case of mucosal injury, there was a significant difference between the two groups at the ninth (P=0.029), tenth (P=0.047) and twelfth (P=0.020) times, and the number of people who suffered after suction There were mucosal damage in the Foley catheter suction group compared to the Nelaton suction group.

Since the use of Foley catheters for suctioning the tracheal tube of patients hospitalized in the intensive care unit causes less pain and mucous membrane than the Nelaton catheters, it is suggested that an arrangement be made to use this method for suctioning the tracheal tube. Patients should be given more attention..

Nurses face conditions that can adversely affect their quality of professional life due to the care of their clients on a daily basis. Paying attention to the spiritual dimension of human existence plays an important role in his physical, mental, and social health. The aim of this study was to determine the effect of spiritual care training on the quality of professional life of nurses in intensive care units.

The present study was an experimental study with a pre-test-post-test design, in which the nurses in intensive care units of hospitals affiliated with Isfahan University of Medical Sciences were studied in the first half of 2021. Forty nurses were selected through the convenience sampling method and randomly divided into experimental and control groups by lottery method. For the experimental group, spiritual care was taught by the researcher in 8 one-hour group sessions in one month, two sessions per week in groups of 5 people in the conference hall of the hospital in the form of lectures and group discussions, with the content of the importance of spirituality and spiritual care. Figley and Stamm's (2002) professional quality of life questionnaire was used for data collection. Data were analyzed by SPSS version 21 statistical software and using Fisher's exact tests, chi-square, independent and paired t.

There was no statistically significant difference between the two groups in terms of demographic variables. The mean scores of burnout, satisfaction, and fatigue due to compassion before the intervention in the two groups were not statistically significant (P> 0.05) but after the intervention these differences were significant and in the intervention group of burnout (P <0.001) and fatigue (P<0.001) decreased and the level of compassion satisfaction (P<0.001) had increased.

Spiritual care training can be helpful and effective in improving the quality of the professional life of nurses in intensive care units, so it is recommended that nursing managers use this intervention to improve the quality of the professional life of nurses.

Clinical education is one of the effective strategies for achieving clinical competence in nursing students. It has been found that clinical training with peer assisted learning method engages students in clinical teaching and learning and improves their psychomotor skills as well. The goal of this study was the evaluation of nursing students’ satisfaction with peer group clinical teaching method.

This quasi experimental study has been carried out on 71 internship and trainee students whom were randomly selected in two intervention and control groups in hospitals related to Islamic Azad University of medical sciences. The trainee students were trained by internship students in intervention group, while control group were taught by instructors. At the end of course, satisfaction questionnaire was completed by all students in both groups. The validity and reliability of the questionnaire were confirmed by content validity and test-re- test respectively. Data analysis were done by SPSS-ver16 softwarw. P<0.05 was considered as significant.

The data analysis showed that the mean and standard deviation of satisfaction score in both internship (76.16± 12.62) and trainee (76.33±13.96) students in intervention group was significantly higher than control group (66.85±15.48 in internship and 65.25±16.23 in trainee) (p=0.001).

Peer assisted learning method increases the student satisfaction and could be used as a part of educational program.

A Zn-based metal–organic framework (Zn-MOF) was synthesized by a novel electrodeposition method. The prepared Zn-MOF was characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy techniques. The supercapacitive behavior of synthesized MOF was examined using cyclic voltammetry (CV), galvanostatic charge/discharge, and electrochemical impedance spectroscopy (EIS) measurements in 3 M KOH. SEM images confirmed that Zn-MOF is composed of layered cuboid structure properly attached on to nickel foam substrate. Electrochemical behaviors of the Zn-MOF/Ni foam were also evaluated through GCD tests, which showed high specific capacitance of 288 F g–1 at the current density of 2 A g–1. The outcomes showed great potential of fabricated Zn-MOF as a high-performance electrode material for electrochemical supercapacitors.

Fatigue and shortness of breath are the main complaints of patients after COVID-19 disease, and Determine the factors associated with them is very important for effective care of these patients. The aim of this study was to investigate the relationship between fatigue severity and shortness of breath with arterial blood oxygen saturation (SPO2) in COVID-19 patients.

The present study was a cross-sectional study. 193 patients with COVID-19 admitted to Fatemeh Al-Zahra and Lolagar hospitals in Tehran in the second half of 2021 were selected through convenience sampling method. Demographic information questionnaire, fatigue severity scale, Modified Borg Dyspnoea Scale and recording SPO2 form were used to collect data. Data were analyzed using SPSS26 statistical software using statistical tests.

In total, 56.5% were women, 72% were married, 40.9% were housewives and 82.9% were over 40 years old. Patients 'fatigue intensity (35±17.55) was low, arterial blood oxygen saturation (89.74±5.35) and patients' shortness of breath (3.35±2.03) were at the level of light activity. Based on the results, the relationship between fatigue intensity and oxygen saturation was not significant (P=0.246). There was a significant negative relationship between the severity of shortness of breath and SPO2 (P=0.005, r=-0.202). As the severity of shortness of breath increases, the SPO2 decreases.

The fatigue severity in patients with COVID-19 was moderate and the severity of shortness of breath was high, which should be given more attention as a traumatic complication. Also, due to the significant relationship between the severity of shortness of breath and arterial blood oxygen saturation, it is necessary for nurses caring for these patients to be reminded of the importance of measuring oxygen levels to seek the help of nurses and physicians in emergencies.

Patients undergoing hemodialysis have a lower quality of life due to limitations, stress, and socio-supportive deficiencies that should be considered in nursing interventions. The purpose of this study was to determine the effect of the implementation of an empowerment program on the quality of life of patients undergoing hemodialysis in hospitals affiliated with Kermanshah University of Medical Sciences in 2020. 

The present study was an experimental study with a pre-test-post-test design and its statistical population was all patients in hemodialysis wards of Imam Reza and Imam Khomeini hospitals affiliated to Kermanshah University of Medical Sciences in the second half of 2020. Through a Purpose-based sampling method and based on inclusion criteria, 70 patients were selected and randomly divided into intervention and control groups using a table of random numbers. For the intervention group, 4 sessions of empowerment training were held using the teach-back method with a one-month follow-up by telephone. Samples completed a quality of life questionnaire for kidney patients before and after the intervention. Data were analyzed using SPSS21 statistical software using statistical tests.

There was no statistically significant difference between the two groups in terms of demographic variables. The mean scores of patients' quality of life before the intervention in the intervention group was 36.18 ± 3.78 and in the control group was 36.76 ± 3.95 which was not statistically significant (P = 0.54) which after the intervention in the intervention group It reached 43.93 ± 3.60 and in the control group it was 36.98 ± 12.4 and this difference was significant and in the intervention group, the quality of life improved (P <0.001).

Implementing an empowerment program through feedback-based education and telephone follow-up to clear up ambiguities and consolidate learning can be useful and effective in improving the quality of life of patients undergoing hemodialysis, so it is recommended that nurses in their training while empowering patients, be sure to get feedback on the accuracy of the lessons learned.

Collagen and omega-3 fatty acids (FAs) are suggested to have anti-inflammatory, anti-oxidant,and insulin-sensitizing properties. The aim of this study was to investigate the effect of collagen hydrolysate andomega-3 FAs on inflammation and insulin resistance in patients with major burns.

In this double-blind randomized clinical trial, 66 patients with 20-45% burns were assigned to either of the three groups ofcollagen (40 gr/d), collagen (40 gr/d) plus fish oil (10 ml/d), or control. High-sensitivity C-reactive protein (hs-CRP), fasting blood glucose (FBG) and insulin concentrations, and homeostatic model assessment for insulinresistance (HOMA-IR) were assessed at baseline, as well as end of weeks two and three.

Based on post-hoc analyses, hs-CRP levels were significantly lower in the collagen (p=0.026) and collagen+omega-3 (p=0.044)groups compared to the control group, at week three. However, pre- to post- (week three) changes of hs-CRPwere significantly higher only in the collagen+omega-3 group compared to the control group (173.2 vs. 103.7mg/l, p=0.024). After three weeks of the intervention, insulin (11.3 and 11.9 vs. 22.8μIU/ml) and HOMA-IR (2.9and 2.8 vs. 7.9) values seemed to be clinically, but not statistically, lower in both intervention groups comparedto the control group. Pre- to post- (week three) values of FBG decreased significantly in the collagen (p=0.002)and collagen+omega-3 (p=0.036) groups. Insulin (p=0.008) and HOMA-IR (p=0.001) decreased significantly onlyin the collagen+omega-3 group at week three compared to the baseline.

Supplementation withcollagen hydrolysate and omega-3 FAs can improve hs-CRP concentration and probably insulin resistance inpatients with severe burns. Omega-3 FAs had additional effects on modulating inflammation. Larger clinicaltrials are needed to confirm the current findings especially in terms of glucose homeostasis.

One of the most important issues in the health care system is the observance of patient safety indicators, especially in special sections.  In this regard, the evaluation of patient safety assessment in intensive care wards is an important issue. This study aimed to evaluate the patient safety assessment indicators in the intensive care wards of private hospitals and educational hospitals of Ahvaz University of Medical Sciences in 2019.

The present study was descriptive-comparative. The statistical population included all nurses in the morning, evening and night shifts in the intensive care units of private hospitals and educational hospitals of Ahvaz University of Medical Sciences. 230 nurses were examined by targeted census. To collect research data, the standard questionnaire of patient safety indicators was used. After collecting data, the research data were analyzed using statistical tests of Mann-Whitneychr('39')s U-analysis in SPSS software.

The results showed that there was a significant difference between the mean index of drug measures, nursing care, patient injury during care, patient identification, patient decline, patient-to-patient training, diagnostic-therapeutic methods, infection control, and blood transfusion. in the intensive care wards of private hospitals and educational hospitals of Ahvaz University of Medical Sciences.

Patient safety assessment indicators in the intensive care wards of educational hospitals of Ahvaz University of Medical Sciences are better observed compared to private hospitals.

Viral myocarditis (VMC) is one of the common heart diseases to endanger human health in different age groups, especially children. The aim of this study was to diagnose VMC in children with clinical suspicion of myocarditis (MCI) using multiplex real-time PCR in Birjand Vali-Asr Hospital.

This cross-sectional study was conducted on 19 patients with clinical suspicion of MCI, who had evidence of infections in the recent weeks. Routine electrocardiogram and dynamic electrocardiogram (ECG) examinations, auxiliary laboratory testing and echocardiographic evaluation were performed. Multiplex real-time PCR was used for detection of viral agents in blood or pericardial fluid samples.

The results indicated that 4 out of 19 (21.05%) MCI patients were virus-positive. The spectrum of viral agents included human herpesvirus 6, 7 (HHV), parvovirus B-19 (PVB19), Epstein–Barr virus (EBV), varicella zoster virus (VZV) and adenoviruses. A co-infection of HHV-6, 7 and PVB19 was found in one patient. The ECG findings such as sinus tachycardia with ST-T changes, premature ventricular contraction and complete heart block were observed in VMC patients. The predominant echocardiographic features in VMC patients were low ejection fraction, mitral regurgitation and severe pericardial effusion with hypotension. Aspartate aminotransferase (AST) and lactic dehydrogenase (LDH) had abnormal increase in some patients.

Our findings highlight the importance of identification of VMC in children with clinical suspicion of MCI. The present study emphasizes the importance of PCR-based assays for detection of viral agents in MCI patients with symptoms of virus infection.

The purpose of this study was to describe and thematically analyze the curriculum research studies to identify the status quo. For this purpose, the quantitative analysis of articles in specialized journals was analyzed based on the thematic framework of the Iranian curriculum encyclopedia. Statistical population of specialized journals articles in the last five years (1392-1397) were selected as the sample (whole population). The data collection tool was a researcher-made checklist based on the Iranian curriculum axis that was validated by expert validation and expert opinion and its reliability estimated through inter-group reliability. Descriptive analysis was used to analyze the findings, which finally showed that among the specialized journal articles, the most thematic distribution of articles is related to the curriculum and content areas; and the least distribution  to the “History”, “ Practical Curriculum Experiences and Curriculum Innovations”, “World Celebrities”, “Basics” and “International Statements and Recommendations “. The research results indicated that the titles and topics of the research were limited to a small number of fields of the curriculum encyclopedia and the repetition and parallelism of the subjects and the lack of attention of the research to the new domains of the curriculum studies.

Congenital heart diseases (CHD) are the most common congenital anomalies in children that can adversely influence children and families mental health, physical performance, and family economic. The aim of present study was to compare the quality of life (QOL) in mothers with children with CHD before and after cardiac surgery in South Khorasan Province (East of Iran).

In this cross sectional study the QOL of 60 mothers with CHD children admitted in Vali-e Asr Hospital were evaluated before and after cardiac surgery in 2017. They were incorporated upon provision of informed consent. The Mac new Heart Disease Health -related quality of life Questionnaire scale was completed by the mothers 10 days before and three months after the surgery. The data were analyzed in SPSS software (version 22) using relative tests. p<0.05 was considered as significant difference.

The results of the present study showed that the mean of QOL score were significantly increased from 40.8±2.7 in initial time to 66.50± 2.2 in 3 months after surgery (p<0.001).

Cardiac surgery in children with CHD could improve the overall QOL score and all of its subscales (physical health, emotional health and social health) of their parents.

Dear Editor-in-Chief: Congenital structural heart diseases are the most commonly reported fatal anomalies in children. These anatomical disorders often can be corrected surgically .Today, echocardiography is the best and most important diagnostic technique for anatomical abnormalities in the heart. In this method, by using the ultrasound waves (sonography), anatomical details, and hemodynamic examination of the heart can be determined . Most pediatric cardiologists provide echocardiographic reports in the form of handwriting or typed text. This method of reporting is sometimes unable to understand the structural anomalies precisely and accurately for the final decision. Nowadays, 2-dimensional echocardiography is acceptable for the diagnosis of some structural heart abnormalities accurately. Even there is no necessary to angiography for surgical planning .2 But sometimes lack matching echocardiographic findings with surgical reports, it seems that adding a schematic figure base on echocardiography findings from the viewpoint of pediatric cardiologist will be the helper to the congenital cardiac surgeon. This proposed method of reporting will lead to the promotion of surgical treatment in congenital heart diseases. The history of the schematic picture in the anatomical textbook for a better understanding of subjects and also diseases has been shown previously by famous painters like Leonardo Davin chi. This suggestion shows that mapping can be viewed as a common language for better understanding of echocardiographic reports and more adaptation between comments of a pediatric cardiologist with designing congenital cardiac surgeon for more precise and complete treatment.

Regular consumption of vitamin D doses can improve heart function in patients with heart failure. The present study aimed to investigate the effect of vitamin D on the recovery process of neonates, infants, and children with Congenital Heart Disease (CHD) following reconstructive cardiac surgery.

In this single-blinded clinical trial study, 60children with CHD requiringreconstructive cardiac surgery, who had been referred to the cardiology department of Razi Hospital affiliated to Birjand University of Medical Sciences, Iran in 2019, were selected and randomly divided to the intervention and control groups. Patients in the intervention group received oral vitamin D before operation (300,000 units of vitamin D). 24 and 48 hours after the operation, patients' hemodynamic conditions were assessed and inotropic drugs were administered accordingly.

The mean vitamin D level was 33.21 ± 4.66 ng/ml in the intervention group (with vitamin D) and 23.55 ± 2.68 ng/ml in the control group (P<0.05). The mean RACH category of the intervention and controlgroups was 2.33 ± 0.15 and 2.2 ± 0.14 respectively; there was no significant difference between the two groups in this regard. The relationship between vitamin D level with RACH category score, inotrope score, and vasoactive inotrope score was not significant at 24 and 48 hours after the operation in both groups. Conclusion According to the results, the administration of vitamin D had no significant effect on the improvement of patients with the congenital cardiac disease after reconstructive heart surgery.

Vitamin D is a fat-soluble vitamin that has an important function in bone metabolism, muscle activity, nervous system, and immunity. In this study, we compared the vitamin D level of children with congenital heart disease (CHD) with healthy control.

This case-control study was conducted on 56 children with CHD diagnosed with echocardiography and 56 healthy children with no sign of CHD matched for age, sex, and use of vitamin D supplementation. Participants were gathered from those who referred to the cardiac clinic of Vali-e-Asr hospital, Birjand, Iran, in 2017. Two ml of the blood sample was taken from all participants and serum vitamin D was assessed using Roche Diagnostic kit (Germany). The data analysis was achieved using SPSS software version 16 with descriptive statistics and Chi-square test.

The median age of participants was 7 months (ranged1-24). The mean vitamin D serum level of all participants was 32.19 ng/ml (SD=28.79) (normal > 20). The level of vitamin D in the case and control group was 16.82 ng/ml (29.85-9.38), and 34.95 ng/ml (46.60-26.52), respectively; and this difference was significant (P<0.05). In the CHD patients group, 15 patients had vitamin D deficiency and 5 patients had high vitamin D levels. In the healthy patients’ group, these numbers were 2 and 21, respectively.

Based on the results, children with CHD had significantly lower levels of vitamin D; therefore, we suggest more vitamin D supplement be used for patients with CHD than healthy children.

Metal-organic frameworks (MOFs) are a class of hybrid porous materials made up of inorganic clusters connected with organic linkers, offering many opportunities for applications in different areas from catalysis to magnetism. A Dysprosium-organic framework was prepared by a hydrothermal reaction. The prepared MOF was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Brunauer−Emmett−Teller (BET) surface area analysis and X-ray powder diffraction (XRD). Herein, Dy-MOF was used as a Lewis acid heterogeneous catalyst for sulfoxidation and as a precursor for the formation of micro-scale Dy2O3 particles. Based on the spectroscopic and microscopic analysis, Dy-MOF can catalyze the sulfide oxidation reaction to sulfoxide and the framework remains intact after the catalytic reaction. Also, the crystals of Dy-MOF turn into particles of Dy2O3 when heated at 650 °C in the air . This result suggests an approach for the formation of dysprosium oxide with  a well-defined (uniform) morphology.

Hospitalization of neonates in intensive care unit leads to psychological vulnerability of their mothers so that they need urgent care support. Given the impact of psychological empowerment on coping with stressful situations, this study aimed to determine the effect of psychological empowerment training on maternal resiliency of premature neonates hospitalized in intensive care unit.

This study was a quasi-experimental, single-group pre-test and post-test study in which 40 mothers of premature infants admitted to neonatal intensive care unit were enrolled. The psychological empowerment training program for mothers was conducted in 7 sessions of 45 minutes in groups of 4-5. Before and after the intervention, the data were collected using demographic questionnaire and Conner Davidson questionnaire and analyzed using appropriate statistical tests.

The results showed that the mean score of resiliency and all its subscales after intervention were significantly higher than before. The mean total resilience score was increased from 33.93 ±9.75 to 72.45 ±5.63 (P <0.001).

Psychological empowerment training can increase maternal resiliency of neonates hospitalized in intensive care units. Therefore, due to the important role of mothers in the care of premature infants admitted to intensive care units, increased maternal resilience can lead to improved care of premature infants.

The quality of nursing services and, consequently, the health of the community has a direct relationship with nurses' job satisfaction. Symptoms of nurses' job satisfaction are widespread and can affect the quality of life of nurses, increasing the quality of care and patient satisfaction. The purpose of this study was to determine the relationship between job satisfaction and quality of life of nurses working at khorramabad  university of medical sciences hospitals in 2019.

In this descriptive-correlational study, 200 nurses working at khorramabad  university of medical sciences hospitals in 2019 were selected by size-proportional stratified sampling method. Data collection tools included demographic questionnaire, Minnesota Job Satisfaction Questionnaire, and WHOQOL-BRIEF. Data were analyzed by SPSS16 and descriptive and inferential statistics.

In this study, Nurses' job satisfaction was moderate and their quality of life was poor.The highest mean score in job satisfaction was related to work context (3.48 ± 0.53) and the lowest mean score was related to the payment system(2.09 ± 0.59). Quality of life was highest mean score in mental health(51.77 ± 8.52)  and lowest in physical health(43.14 ± 8.16). Also, there was positive statistically significant correlation between job satisfaction and quality of life (p<0.001, r=0.385).

In the present study, nurses with more job satisfaction had a higher quality of life. Therefore, It is recommended to provideing backgrounds for increasing nurses' job satisfaction to improve their quality of life and provide better professional services.

Congenital heart disease (CHD) occurs in about 8 cases per 1,000 live births and is responsible for 30% of all neonatal deaths. The reportedly high prevalence of CHD underscores the necessity of the implementation of local evaluations and screening programs in order to plan for appropriate interventions. Regarding this, the present study was performed to determine the prevalence of CHD and its associated risk factors among the newborns with respiratory distress and cyanosis admitted to Vali-e-Asr Hospital in Birjand, Iran, in 2016. This cross-sectional analytical study was conducted on the records of 199 neonates admitted to the Neonatal Unit of Vali-e-Asr Hospital due to respiratory distress and cyanosis in 2016. The data were collected using a predesigned form covering such information as gender, type of delivery, and gestational diabetes. Data analysis was performed in SPSS software (version 22) using the Chi-squared test. P-value less than 5% was considered statistically significant. Out of the 199 neonates enrolled in this study, 168 (84.4%) cases suffered from CHD. Patent ductus arteriosus (PDA) was the most common anomaly among the neonates (n=85, 50.5%), followed by atrial septal defect (n=41, 24.4%), ventricular septal defect (n=36, 21.4%), transposition of great arteries (n=4, 2.2%), and other complex heart anomalies (e.g., shone complex; n=2, 1.1%), respectively. The results revealed that the presence of CHD, especially PDA, in neonates was associated with their parental interfamily marriage (P=0.024). The high prevalence and mortality of CHD necessitate the control of premarital and preconception potential risk factors (e.g., inter-family marriage) and preparation for the implementation of effective interventions for the neonates with respiratory distress and cyanosis.

Brucellosis is one of the most important zoonosis. It causes significant economic and medical problems in countries throughout the world, including Iran. According to the available literature, brucellosis rarely causes intracranial space-occupying lesions. In this case study, we reported an intracranial mass in a 52-year-old male who were affected with brucellosis. The patient was referred to Vali-e-Asr hospital with right hemiparesis and transient speech impairment. The symptoms had begun sub-acutely and had gradually progressed. His past medical history was completely normal. Moreover, he had not consumed raw meat, had not been exposed to animal bite and slaughter within the recent weeks. In the initial assessment, the results of Wright agglutination and Coombs Wright tests level were 1/640 (a Wright’s titer of less than 1/80 is considered normal in Iran). The serum level of 2-Mercaptoethanol was 1/320 that was higher than the normal value. Brain-computer tomography (CT) scan and magnetic resonance imaging (MRI) were performed due to the inconsistency of neurologic findings with the usual presentations of brucellosis. MRI and CT scan findings showed a 35×35×34 mm heterogeneous mass lesion containing multiple vascular components located in the left paraventricular region along with mild peripheral edema and mass effect. Due to the size and the location of the lesion and the neurosurgery consultation, surgery was avoided and follow-up suggested. Treatment of brucellosis was initiated and completed according to the national protocol with rifampin and doxycycline. Follow up were performed in 6, 12, and 24 months after completion of the treatment. The growth of brain lesion was also controlled and the serologic test results of brucellosis were obtained normal.

Teaching and learning from peers is an effective educational intervention for health science students in clinical settings. Peer assisted learning is a situation in which people of an equal social group, who are not professional teachers help others to learn and they learn during teaching at the same time. The aim of this study was investigating the effect of using Peer Assisted Learning approach on clinical self-efficacy of nursing students in selected fields of Islamic Azad University of Medical Sciences in Tehran.
This study was a quasi-experimental and case-control research. Sampling was Census method and included 150 people. These subjects were divided into two groups of case and control by simple random sampling; the control group with conventional methods (by clinical instructor) and case groups by peer learning, experienced clinical education for 3 weeks. Data collection tool was included psychometric questionnaires by Cheraghi and et.al to assess self-efficacy in clinical practice with 4-point Likert scale in 4 domains. All students completed questionnaires before and after training. For data analysis were used software SPSS (Ver22) in descriptive level (measure of central tendency) and inferential statistics (independent t test, Chi-square and covariance analysis). In this study P˂0.05 was considered significant.
Descriptive findings show that with the loss of 9 people, 141 nursing students participated in the case group (68 students) and in the control group (73 students) finally. Students of the two groups did not differ significantly in terms of age, gender and habitat (native and non-native). The results of covariance assumptions showed that due to non-violation of the linear assumption, the homogeneity of the studied regression slope and the variance consistency of the data of the under study groups, research hypothesis have been confirmed(pIt seems that the use of Peer Assisted Learning approach has been effective in improving patient care dimensions by increasing the self-efficacy of students.

Congenital heart abnormalities are the most common type of congenital conditions in children. Annually,about 1 to 2 percent of children are born with these diseases. As chronic diseases, congenital conditions of children usuallycause limitations in the quality of their lives, especially if they are in need of frequent and complex surgical procedures. Regarding the role of parents, especially mothers, in the care of these children, their quality of life is of particular importance. This study, therefore,aimed to evaluate and compare the life quality of mothers with healthy children and mothers with children with a congenital heart disease in need of surgery.
This research is a cross-sectional descriptive-analytical study, in which 100 mothers of healthy childrenand 60 mothers ofchildren with severe congenital heart disease – who were referred to Birjand Valiasr Hospital in 2017 –were entered into the study. The life quality of the mothers was assessed using the Life Quality Questionnaire of World Health Organization (WHOQOL-BREF). Data were analyzed by SPSS software (version 22). P-values less than 0.05 were considered significant.
According to the findings of this study, the age means of the mothers with healthy children and that of mothers of children with congenital heart diseasewere 31.91±8.57 and 32.48±6.46 years, respectively. The mean score of life quality of motherswith healthy children was 71.25±16.43; it was 41.25±19.27 for mothers ofchildren with congenital heart diseases in need of surgery. Life quality and all its sub-scales (social relationships, mental health, environmental health and physical health) were significantly higher in mothers with healthy children than in mothers ofchildren with severe congenital heart diseases in need of surgery before operation(P It was found that the life quality of mothers with children with severe congenital heart disease was significantly different from that ofmothers with healthy children. Therefore, in order to improve their quality of life, appropriate planning in different areas should be performed.
