RESUMO
OBJECTIVE: The aim of this systematic review and meta-analysis study was to determine the pooled estimate of the effect of antenatal magnesium sulfate (MgSO4) on intraventricular hemorrhage (IVH) in premature infants. METHODS: Two review authors independently searched all randomized clinical trials from international databases, including Medline (PubMed), Web of Sciences, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Research Registers of ongoing trials (ClinicalTrials.gov), from January 1989 to August 2017. Two independent review authors were responsible for data collection. After extracting the necessary information from the evaluated articles, metaanalysis of the data was performed using Stata version 14. Also, sources of heterogeneity among studies were determined by Meta regression. RESULTS: In this study, among 126 articles that were extracted from primary studies, 7 papers that evaluated the effect of MgSO4 on IVH were eligible for inclusion in the meta-analysis. The results of the meta-analysis showed that pooled relative risk (95% confidence interval [CI]) was 0.80 (95% CI, 0.63 to 1.03) for the effect of MgSO4 on IVH. RESULTS: of this study showed that although MgSO4 had a protective effect on IVH in premature infants, this effect was not statistically significant. Further studies are needed to determine the best dosage, timing, and gestational age to achieve the optimum effect of MgSO4 on IVH.

RESUMO
The present study is aimed at examining the status of violence among the students of nursing, midwifery, and operating room. A self-reporting questionnaire with two sections of demographic characteristics and experience of violence was used. The data obtained were analyzed, using SPSS software. 58.7 percent of the students had a history of violence in the previous year. The maximum percentage of violence exposure belonged to the students of operating room (76.9%). The highest incidence of violence was verbal (76.4%), happened in patients' rooms (32.9%) and was in the form of insult (75.1%). Accordingly, preventive actions are required to prevent and control violence and support students. Informing students about violence, communicative skills, reaction, and coping with violence during studying is necessary. Therefore, educational authorities and theoretical and clinical instructors should take appropriate measures in order to prevent violence and create supportive mechanisms for the students.
