In developing countries or economies in transition, many people die because of lack of safe blood, even in some urban healthcare facilities. Blood transfusions can save lives and improve health, but millions of patients did not timely access to safe blood, due to no reliable blood donors. The objective of this study was to determine the prevalence of hepatitis B in blood donors from the Sendwe General Provincial Hospital. This is a retrospective cross-sectional descriptive study on serum markers of hepatitis B study taking place over a period of 12 months from 1 January to 31 December 2014. This study showed that the prevalence of hepatitis B was 6.8%, and 78.7% of donors were male. The mean age was 34.1 ± 7.4 years, ranging from 18 to 57 years. Married, family donors, blood type O and Rh positive were the most represented with 81.1%, 68.6%, 58.8% and 99.3% respectively. A significant association was observed between the prevalence of hepatitis B and age, civil status of blood donors (p ≤ 0.001). These results should encourage health authorities to the implementation of effective prevention methods to stop the rapid spread of this infection, which is a serious public health problem.

Objectives: The objective of this work was to analyze the etiologies of maternal deaths occurring in a tertiary hospital. Methodology: This is a descriptive cross-sectional study with retrospective data collection of maternal deaths that occurred in the reference provincial hospital Jason Sendwe from 2013 to 2015. All cases of maternal deaths in line with the definition of World Health Organization have been included. Data were analyzed by the software Epi info and Excel 2010 7.1.4.0. Results: Seventy seven (77) maternal deaths were identified during the study period. 74.03% of deaths occurred direct obstetric causes. Bleeding with 61.04% was the leading cause of maternal death followed by eclampsia (31.58%). Indirect causes were dominated by heart disease (30.0%). Note that 75.32% of deaths had occurred within 24 hours of admission. Conclusion: haemorrhage, eclampsia and infections are the main causes of maternal deaths in our study. The reduction of maternal deaths happens through access to emergency medication, transfusion and anesthetic and surgical teams in hospitals but also through the involvement of religious leaders, traditional and any community to better understand the population obstacles to reducing maternal mortality.

The objective of this study was to identify and explain the factors influencing the birth of underweight children in the city of Mbuji-Mayi. Methods: This is not a paired case-control study of births registered from 1 to June 30, 2015 in maternity hospitals in three health zones selected for this study, cases are all children born with low weight and witnesses are all children born with a normal weight is 2500 g and more. The significance level was set at p < 0.05.

Seroprevalence among blood donors is a major public health problem, both in developed and developing countries, in its magnitude. The aim of this study was to determine the seroprevalence of hepatitis B in blood donors. This is a descriptive study carried out in the city of Mbuji-Mayi at the General Hospital of Dipumba in blood donors (family, volunteer and remunerated) recorded from 01/to31/December 2016; the data were collected in a transverse fashion. The following observations were made: During the study period, 1584 blood donors were registered. After analyzing the data, the seroprevalence of hepatitis B in blood donors was 2.2%, 77.8% were male (sex ratio M/F 3.5 and voluntary donors were 50.4%.

Introduction: Pregnancy is a special natural and physiological event that is not always normally and is responsible for morbidity and preventable mortality. Pregnancy risk is defined as one that is complicated by a factor or factors that negatively affect the outcome of pregnancy the mother's side and/or perinatal. This study was assigned as targets to determine the risk pregnancy prevalence and the factors associated with these pregnancies. Materiel and Method: We conducted a cross-sectional descriptive study at the General Hospital Katuba in Lubumbashi for a period of three months from March to June 2017. Result: Our results showed that 11.5% of pregnancies were high risk and moderate in 21.6%. Overall, pregnancies were high or moderate risk of 33.1%. A proportion of 19.8% of new mothers were aged over 35 years and 3.4% were under 18 years. The average age was 28.8 ± 7.2 years. Age greater than 35 years, multiparity, the high parity, the multigestity and the large multigestity were significantly associated with a risk
