Introduction: Surgical site infection (SSI) constitutes a substantial complication after knee arthroplasty, contributing to notable morbidity. This study aimed to review the existing literature on the incidence and risk factors of SSI following knee arthroplasty. Methods: A systematic search was undertaken across various international electronic databases, including Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex and the Scientific Information Database. The search strategy involved the use of keywords derived from Medical Subject Headings, such as “incidence”, “Surgical wound infection”, “Surgical site infection”, and “Arthroplasty”, covering records from the earliest available up to March 17, 2024. Results: The study incorporated a collective participant group of 1,366,494 knee arthroplasty procedures from twenty-three chosen studies. The pooled incidence rate of SSI after knee arthroplasty was 1.7% (95% confidence interval (CI): 1.1% to 2.6%; I²=99.687%; P

Introduction: Considering the priority of supporting vulnerable groups when fighting against COVID-19, the present study aimed to evaluate the levels of COVID-19-induced anxiety and depression in two vulnerable groups: medical staff and pregnant women.Methods: The present study is a descriptive cross-sectional study performed on 140 treatment staff and 338 pregnant women. The questionnaire used in this study includes demographic characteristics and the Hospital Anxiety and Depression Scale- modified. Univariate and multiple linear regression analysis and analysis of variance were used to identify the effect of variables on anxiety and depression.Results: Among the staff, 88.6% were women. The mean and standard deviation of their COVID-19-induced anxiety and depression were 12.76 ± 1.78 and 7.75 ± 2.27, respectively. The staff exhibited high levels of abnormal anxiety, with 92.9% reporting symptoms. In contrast, the prevalence of abnormal depression among the staff was lower, with only 11.4% reporting symptoms. Marital status (p=0.05) and exercise (p=0.03) significantly affected the covid-19-induced depression of the medical staff. The mean and standard deviation of COVID-19-induced anxiety and depression in pregnant women were 10.53 ± 2.04 and 11.15 ± 2.09, respectively, and these scores were significantly different compared to the medical staff groups.Conclusion: Vulnerable groups had high levels of anxiety and depression associated with COVID-19. Nurses prioritized psychological programs targeting anxiety reduction, while pregnant women prioritized psychological programs addressing depression reduction.

Background: The importance of patient safety competency in nursing students to enter the clinical environment has made continuous studies necessary. However, only few studies have been conducted to assess and compare patient safety competency and its related aspects among nursing students in various settings. Purpose: This study aimed to compare patient safety competency and its related aspects among undergraduate nursing students of two nursing schools. Methods: This descriptive comparative study was conducted at two nursing schools (A and B) in Iran. Using a census method, 240 undergraduate nursing students were enrolled from group A and 200 ones from group B. In total, 377 students completed the survey (response rate = 76.60 %). Data were collected using the adapted Health Professional Education in Patient Safety Survey (H-PEPSS). Data were analyzed using SPSS (version 21) and running descriptive statistics and independent samples t- test. The significance level was set at p
