Background: Obstructed labor accounted for 22% of obstetrical complications and 9% of all maternal deaths in low- and middle-income countries. Even though there are separate studies regarding obstructed labor and its complication in Ethiopia, their results are inconsistent. The objectives of this review will be to estimate the pooled the prevalence of obstructed labor and to identify adverse feto-maternal outcomes associated with obstructed labor in Ethiopia. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline will be followed to conduct this systematic review and meta-analysis. The databases we will search will be PubMed, Cochrane Library, Google Scholar, CINAHL, African Journals Online, Dimensions, and Summon per country online databases. To search the relevant literature, we will use the following key search terms: "prevalence," "adverse outcome," "obstructed labour," "maternal near miss," "neonatal near miss," "perinatal outcome," "cesarean section," "obstetric fistula," "uterine rupture," and "Ethiopia." Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument will be used for evaluating the quality of the studies. Appropriate statistical tests will be conducted to quantify the between studies heterogeneity and for the assessment of publication bias. We will check individual study influence analysis and also do subgroup analysis. The STATA version 15 will be used for statistical analysis. Discussion: Our systematic review and meta-analysis will provide the pooled prevalence of obstructed labor and its association with adverse feto-maternal outcomes in Ethiopia. The finding of this study will be helpful to design appropriate preventive and promotive strategies for reducing of obstructed labor-related maternal mortality. Systematic review registration: PROSPERO CRD42020196153. [ABSTRACT FROM AUTHOR]

Introduction: Globally, more than 257 million people are living with chronic hepatitis B virus (HBV) infection, which is a major cause of morbidity and mortality in Africa and Asia. The nationwide disease burden of chronic HBV in Ethiopia is estimated to be approximately 8%. Thus, determining the factors associated with HBsAg seroprevalence in different geographical settings and in different population sub-groups is paramount in designing appropriate preventative measures. Aim of the research: To identity the burden of hepatitis B surface antigen sero-prevalence and associated factors among pregnant women. Material and methods: A cross-sectional study was conducted at Jinka Hospital among pregnant mothers. A pre-tested, semi-structured questionnaire was administered by an interviewer and used to collect the data. Serum was obtained from each study subject and used to test for hepatitis B surface antigen (HBsAg) with an enzyme-linked immunosorbent assay test kit. Descriptive, bivariate, and multivariate logistic regression analyses were performed to identify associated factors. Odds ratio and 95% confidence interval were used to determine the degree of association. Results: The HBsAg seroprevalence was nine percent. Scarification (adjusted odds ratio (AOR) = 4.43, 95% CI: 1.77-11.06), having multiple sexual partners (AOR = 4.70, 95% CI: 1.66-13.29), and having a sexually transmitted infection in the past (AOR = 5.57, 95% CI: 2.35-13.17) were significantly associated with HBsAg seroprevalence. Conclusions: The HBsAg seroprevalence among pregnant women was high according to the World Health Organization (WHO) classification criteria. The study identified different factors associated with HBsAg seroprevalence. A properly designed intervention strategy that will lead to reduction of HBsAg seroprevalence, including routine screenings and vaccinations, is warranted. [ABSTRACT FROM AUTHOR]
