Maternal and child health is an important part in the health development plans in many countries. This descriptive study aimed to investigate the epidemiology of risk pregnancies managed at the provincial hospital Janson Sendwe. It was conducted from March 17 to July 15, 2015 to all pregnant women for childbirth consultant beyond 28 weeks of gestation and having at least one risk factor identified during antenatal care or a posteriori childbirth. On 535 women included in the study, we recorded 1667 risk factors in an average of 3.2 risk factors per woman. The three main risk factors were met by order of importance: the history of maternal infection (18.5%), the history of caesarean section (13.6%) and unexplained fetal or neonatal death antecedent (12.4%). The antecedent of uterine malformation (0.1%), the history of macrosomia (0.5%) and uterine height decreased (2.1%) were the least represented. It thus appears necessary to carefully monitor these women to avoid the occurrence of maternal mortality.
The absolute necessity of water in the life of man remains undeniable to the point that some people think the water is the life. Metals are ubiquitous in surface waters. But their concentrations are generally very low which explains their name "trace metals" or "trace metals". However, when the mining begins operating a metal-rich deposit, a change operates especially in waters in contact with these mining works. This study aims to determine the pH of the river water Lubumbashi, and then measure the accumulation of trace elements in the food chain in order to evaluate the risks to human health. The pH of the recorded values are within normal limits (6.5 -9.5); Site 1 has an average pH of 7.962 (±0.185); the site 2 and 3 had a pH of 8.140 (±0.210) and 8.331 (±0.082) respectively. The samples of water show very low levels of metals which not exceed normal values with the exception of the Cd. This mineral element presents concentrations higher than 0.003 mg/l. The pH of the river Lubumbashi water meets drinking water standards accepted by the WHO. The Cd that has very high concentrations may contribute to the pollution of How to cite this paper:
