In highlighting these issues, this article may provide a useful starting point for the development of an educational framework for preparing nurses and other health professionals to work in the disaster setting.

COVID‐19 outbreaks appear to be related to exacerbation of psychological problems such as depression and anxiety in high‐risk population such as pregnant women and the postpartum period due to stress and life‐threatening illnesses. The aim of this study was to evaluate the prevalence of postpartum depression (PPD) during COVID‐19. This study protocol is registered in PROSPERO with CRD42021278425 code. Data sources including Google Scholar, ISC, Magiran, Scopus, PubMed, Embase, and Web of Science and reference list of included articles were used to identify related studies. Observational studies that reported the prevalence of PPD in both Persian and English during COVID‐19 between January 20, 2020 and August 31, 2021 were included. Data were collected and analyzed with a random effects model for meta‐analysis. In this study, 671 initial articles were identified and after removing duplicates, 454 studies were screened and finally 24 studies entered the meta‐analysis stage. According to this study results PPD based on Edinburgh Postnatal Depression Scale (EPDS) ≥9, EPDS ≥10, EPDS ≥11, EPDS ≥12, EPDS ≥13, Postpartum Depression Screening Scale‐Short Form (PDSS‐SF) ≥17 and total prevalence was reported 12% (95% confidence interval [CI] = 0.07–17, I2 = 97%), 27% (95% CI = 15–39, I2 = 99%), 44% (95% CI = 40–49, I2 = 0.0%), 27% (95% CI = 0.06–49, I2 = 97.4%), 28% (95% CI = 18–39, I2 = 98.5%), 37% (95% CI = 32–42), 28% (95% CI = 23–33, I2 = 98.5%). The findings of this study showed that the prevalence of PPD in women is relatively high during COVID‐19. Therefore, considering the psychological consequences of the COVID‐19 pandemic and the importance of pregnancy and the postpartum period in terms of the emergence of mental disorders, especially depression, it seems necessary to perform interventions and physical and psychological support.

Introduction:Concept map is a useful cognitive tool for enhancing a student's critical thinking (CT) by encouraging students to process information deeply for understanding. However, the evidence regarding its effectiveness on nursing students’ CT is contradictory. This paper compares the effectiveness of concept mapping and traditional linear nursing care planning on students’ CT.Methods:An experimental design was used to examine the CT of 60 baccalaureate students who participated in pediatric clinical nursing course in the Shahrekord University of Medical Sciences, Shahrekord, Iran in 2013.Results:Participants were randomly divided into six equal groups of each 10 student, of which three groups were the control group, and the others were the experimental group. The control group completed nine traditional linear nursing care plans, whereas experimental group completed nine concept maps during the course. Both groups showed significant improvement in overall and all subscales of the California CT skill test from pretest to posttest (P < 0.001), but t-test demonstrated that improvement in students’ CT skills in the experimental group was significantly greater than in the control group after the program (P < 0.001).Conclusions:Our findings support that concept mapping can be used as a clinical teaching-learning activity to promote CT in nursing students.

Nurses are the first respondents to the critical situations and therefore must be able to effectively manage the critical situations using their competencies. Given that the decision-making style under the stressful critical situations is an important component of the care process in these situations, this study was conducted with the aim of determining the relationship between decision-making style and nurses’ disaster response competencies. This descriptive, analytical study was conducted in Shahr-e Kord city in 2018. A total of 300 nurses were selected from Ayatollah Kashani and Hajar hospitals by multistage sampling and from the Emergency Medical Services Center by the census method. Data were collected using the Disaster Nursing Competence Assessment and the decision-making style questionnaires and analyzed with SPSS 21 (IBM Corp, Armonk, NY). Most of the nurses used the intuitive decision-making style and the total score of disaster nursing competencies was 162.58 ± 22.70. Pearson’s correlation coefficient indicated that there was a positive relation between decision-making style and nurses’ disaster response competencies. The results show that decision-making style affects nurses’ competencies for disaster response and provides evidence for the development of educational policies in disaster nursing education.

Introduction.One of the diabetes complications in men is infertility. C-peptide and Nicotinamide have antidiabetic and antioxidant activity. So, the aim of this study was to investigate the effects of these drugs on male infertility caused by diabetes.Methods. In this experimental study 40 adult male NMRI mice (20-25g) were obtained and randomly divided into 5groups: controls, diabetes model, diabetes+C-peptide, diabetes+Nicotinamide, d i a b e t e s + C -p e p t i d e + N i c o t i n a m i d e . Diabetes induced was confirmed 3 days after administration of a single dose of streptozotocin (STZ) (65mg/kg) 15 min after an intraperitoneal injection of Nicotinamide (120mg/kg). Then C-peptide (25nmol/kg) and Nicotinamide (100mg/kg) were injected for 28 days. 24h after the last drugs injection serum samples, testes and cauda epididymis of animals were removed for hormonal, testis morphology and sperm count assessment.Results. Diabetes induced could decrease serum testosterone level and sperm count significantly (p<0.001, p<0.05 respectively). Serum LH, testosterone levels and sperm count increased in Diabetes+C-peptide+Nicotinamide versus diabetes group (p<0.05, p<0.001, p<0.01 respectively). Also administration of Nicotinamide alone showed an increase in serum testosterone (p<0.001).Conclusion. The results of this study demonstrated that combined administration of Nicotinamide and C-peptide improved diabetes induced male reproductive disorders by enhanced serum LH, testosterone levels and sperm count in diabetic mice.
