Background Urinary tract infection (UTI) is a common clinical problem in pregnant women. Bacteriuria in pregnancy without antibiotic treatment could result in complications. This study aims to investigate the etiology and prevalence of UTI and asymptomatic bacteriuria (ASB) in pregnant women in Iran. Method This meta-analysis follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. To avoid bias, all steps of the study were carried out independently by two researchers. We conducted a comprehensive search on all the related literature in national databases, including IranDoc, SID, Barakat Knowledge Network System, RICST, Magiran, Iranian National Library and international databases, including Scopus, Embase, Science Direct, PubMed/ Medline, Cochrane Library, Web of Sciences, EBSCO, as well as Google Scholar search engine until June 2018. After considering the inclusion/exclusion criteria and qualitative evaluation, studies were analyzed based on random effects model using Comprehensive Meta-Analysis Software Version 2. Results In 31 studies with a sample size of 20,309, the prevalence of ASB in pregnant Iranian women was estimated to be 8.7% (95%CI: 7.2–10.4). The lowest and highest prevalence of ASB were observed in the third trimester (6.1% [95%CI: 2.1–16.4]) and first trimester (11.7% [95%CI: 7.9–16.9]), respectively. Subgroup analysis of the prevalence of ASB based on geographical region ( P = 0.002) and province ( P <  0.001) was significant but for the quality of studies ( P = 0.51) was not significant. In 17 studies including 48,731 pregnant women, the prevalence of UTI was estimated to be 9.8% (95%CI: 7.6–12.5). The test for subgroup differences of prevalence of UTI for province ( P <  0.001) was significant but for geographical region ( P = 061) and quality of studies ( P = 0.11) was not significant. Meta-regression model for the prevalence of UTI and ASB in pregnant women in Iran based on year of the studies was significant ( P <  0.001). The most common microorganism involved in the etiology of UTI (61.6% [95%CI: 51.6–70.7]) and ASB (63.22% [95%CI: 51.2–73.8]) was E. coli . Conclusion UTI and ASB are prevalent in pregnant women in Iran. Therefore, UTI screening is essential in pregnant women. The most common microorganism involved in the etiology of UTI and ASB in pregnant women in Iran is E.coli .

Objectives: Pregnant women are among the most vulnerable groups for Helicobacter pylori infection. The infection may cause nausea, vomiting, anemia, fetal growth restriction, fetal anomalies and low birth weight of infants. H. pylori prevalence during pregnancy is vary widely between different geographical regions and given the importance of this infection in pregnancy, systematic review and meta-analysis has been done. Materials and Methods:The current study has been conducted based on PRISMA guideline. The time interval of the investigated studies was from the beginning of 2000 until March 2016. In order to achieve the related literature, databases sources such as Scopus, PubMed, Science Direct, Cochrane, Embase, Springer, Wiley online library, as well as Google Scholar search engine was used. The search was done using Mesh keywords. Furthermore, all the articles that met the inclusion criteria were evaluated. The data has been analyzed using the random-effects models for meta-analysis and the Stata 11.1. Results: In 24 studies, a total of 19426 pregnant women had been investigated. The worldwide prevalence of H. pylori infection in pregnant women was calculated to be 46% (95% CI: 38-54). The lowest prevalence of H. pylori infection was seen in Europe, 25% (95% CI: 9-40) and the highest prevalence in South America 62% (95% CI: 53-71 IntroductionThroughout the history of the world, the ones who had confronted the bitterest face of poverty and war had always been the women. As known poverty and war affects human health either directly or indirectly, the effects of this condition on health and status of women in the society should not be ignored. This study intends to cast light on the effects of war and poverty on the reproductive health of women. For this purpose, the face of war affecting the women, the problem of immigration, inequalities in distribution of income based on gender and the effects of all these on the reproductive health of women will be addressed.

Experimental and clinical evidences support the hypothesis that the modulation of the gut microbiota by probiotics could be effective in prevention and management of diabetes.

Background:The clinical consequences of hypothyroidism and hypothyroxinemia during pregnancy such as preterm birth are not still clear. Objective: The aim of this meta-analysis was to estimate the relation of clinical and subclinical hypothyroidism and hypothyroxinemia during pregnancy and preterm birth.Materials and Methods: In this meta-analysis, Preferred Reporting Items for Systematic review and Meta-Analysis were utilized. Searching the cohort studies were done by two researchers independently without any restrictions on Scopus, PubMed, Science Direct, Embase, Web of Science, CINAHL, Cochrane, EBSCO and Google Scholar databases up to 2017. The heterogeneity of the studies was checked by the Cochran's Q test and I2 index. Both random and fixed-effects models were used for combining the relative risk and 95% confidence intervals. Data were analyzed using Comprehensive Meta-Analysis software version 2.Results:Twenty-three studies were included in the meta-analysis. The relative risks of the clinical hypothyroidism, subclinical hypothyroidism and hypothyroxinemia during pregnancy on preterm birth was estimated 1.30 (95% CI: 1.05-1.61, p=0.013, involving 20079 cases and 2452817 controls), 1.36 (95% CI: 1.09-1.68, p=0.005, involving 3580 cases and 64885 controls) and 1.31 (95% CI: 1.04-1.66, p=0.020, involving 1078 cases and 44377 controls), respectively.Conclusion: The incidence of preterm birth was higher among mothers with clinical and subclinical hypothyroidism or hypothyroxinemia during pregnancy compared to euthyroid mothers, and these relations were significant. Therefore, gynecologists and endocrinologists should manage these patients to control the incidence of adverse pregnancy outcomes such as preterm birth.
