BackgroundHepatitis B is the world’s most common serious liver infection. Infection by hepatitis B virus during pregnancy has high rate of vertical transmission and adverse effect on both the mother and child. Data on seroprevalence and associated factors among pregnant women in Dawuro or surrounding was scarce. Therefore, the aim of this study was to assess prevalence of hepatitis B virus and factors associated among pregnant women in Dawuro Zone.MethodsInstitution based cross-sectional study was conducted from 1st April to May 31, 2015 in Dawuro zone. Venous blood was collected, plasma was separated and hepatitis B virus surface antigen was screened using rapid test. Logistic regression was employed with 95% CI and p value of <0.05 was used as statistically significant.ResultsData were collected on 289 women. The overall prevalence from this study was (p = 3.5%, 95% CI 1.4–5.6%) multivariate analysis using logistic regression showed multiple sexual partner (AOR = 6.923; 95% CI 1.685–28.441), and abortion history (AOR = 4.975; 95% CI 1.21–20.456), were significantly associated with hepatitis B virus surface antigen (HBsAg) infection.ConclusionThis seroprevalence was categorized as intermediate endemicity according to WHO classification criteria. Health education on sexual transmission of hepatitis B virus and inclusion of screening hepatitis b virus as routine antenatal care service is recommended.

Background: Cervical cancer screening is a key to detect the pre-cervical cancer earlier, but it is almost not utilized in all developing countries and most cases were diagnosed at late stage of cervical cancer. The current screening level has no much effect to control cervical cancer unless addressing female health workers since they are a role model to the public.

Background: The incidence of colorectal cancer (CRC) and associated mortality are rising in low-and middleincome countries. In Ethiopia, colorectal cancer is among the leading causes of cancer morbidity and mortality in both sexes. Although some studies provided estimations on the national burden and regional distribution, the histological characteristics, survival pattern and determinants among colorectal cancer patients are not welldocumented.Aim: This study aimed to describe the histological characteristics, to determine the patterns of survival, and identify factors that determine mortality rate among CRC patients in Ethiopia. Methods: A retrospective cohort study was conducted among CRC patients registered at cancer treatment center of Tikur Anbessa Specialized Hospital, from January 2012 to December 2016. Data were extracted from a total of 161 patient medical records using a pretested abstraction form and supplemented by phone calls with the patients/caregivers. To determine colorectal cancer specific survival overtime, we performed a Kaplan-Meier survival analysis and significance of variation in survival across covariates and treatment categories was tested using log-rank test. A multivariable Cox proportional-hazards model was performed to identify determinants of survival after diagnosis with colorectal cancer. Results: Overall, the median survival time was 21 months [95%CI: 16-35], with two-, three-and five-year CRCspecific survival rates of 46.8%, 39.5% and 28.7% respectively. In the multivariable Cox regression model, the rate of death due to CRC is significantly higher for patients with elevated baseline carcinoembryonic antigen (CEA) level (Adjusted Hazard Ratio (AHR) ¼ 2.31, 95%CI: 1.27-4.19), stage IV at diagnosis (AHR ¼ 2.66, 95%CI: 1.44-4.91), and mucinous or signet-ring cell carcinoma histology type (AHR ¼ 4.92,). Moreover, patients who underwent surgery showed a better survival than those who did not (AHR ¼ 0.35, 95%CI: 0.14-0.88). Conclusion:In Ethiopia, patients diagnosed with CRC showed a low rate of cancer-specific survival. Histology type, stage of cancer and CEA level at diagnosis, and the type of treatment a patient received significantly determine mortality rate. Hence, cancer screening programs could help to detect the disease at an earlier stage and to initiate available treatments timely so as to extend the lifespan of CRC patients.

Background Extrapulmonary tuberculosis is an emerging public health problem among HIV positives compared to the general population. This study aimed to assess the incidence and predictors of extrapulmonary tuberculosis among people living with HIV in selected health facilities in Addis Ababa, Ethiopia, from 01 January 2013 up to 31 December 2018. Methods A retrospective cohort study design was employed based on data collected from 566 HIV positive individuals. Data were entered using EpiInfo version 7.1 and analyzed by SPSS version 20. The incidence rate was determined per 100 person-years. Kaplan-Meier estimates used to estimate survivor and the hazard function, whereas log-rank tests used to compare survival curves and hazard across different categories. Cox proportional hazard model was used to identify the predictors and 95%CI of the hazard ratio were computed. P-value<0.05 in the multivariable analysis was considered statistically significant. Results Five hundred sixty-six HIV positive individuals were followed for 2140.08 person-years. Among them, 72 developed extrapulmonary tuberculosis that gives an incidence rate of 3.36/100 person-years (95%CI = 2.68-4.22). The most frequent forms of extrapulmonary tuberculosis were; lymph node tuberculosis (56%, 41) followed equally by pleural tuberculosis (15%, 11) and disseminated tuberculosis (15%, 11). The majority (70.83%) of the cases occurred within the first year of follow-up. In multivariable Cox regression analysis, baseline WHO stage III/IV (AHR = 2.720, 95%CI = 1.575-4.697), baseline CD4 count<50cells/μl (AHR = 4.073, 95%CI = 2.064-8.040), baseline CD4 count 50-200 cells/μl (AHR = 2.360, 95%CI = 1.314-4.239) and baseline Hgb<10 mg/dl (AHR = 1.979, 95%CI = 1.091-3.591) were the independent risk factors. While isoniazid prophylaxis (AHR = 0.232, 95%CI =
