In large industrialized cities, tons of particles containing heavy metals are released into the environment and accumulate on street surfaces. Such particles cause a potential risk to human health due to their composition and size. The heavy metal contamination levels, main emission sources, and human health risks were identified in 482 samples of street dust. Heavy metal concentrations were obtained by microwave-assisted acid digestion and ICP-OES. The results indicated that street dust in Mexico City is contaminated mainly with Pb, Zn, and Cu, according to the contamination factor and the geoaccumulation index. The pollution load index of the street dust was made with the concentrations of Pb, Zn, Cu, Cr, and Ni. Binimetinib MEK inhibitor The main sources of Pb, Zn, Cu, and Cr are anthropic, probably due to vehicular traffic. The highest levels of Cr and Pb in urban dust represent a health risk for children. Contamination limits were proposed for heavy metals in street dust of Mexico City. These limits might be useful to generate and apply public policies to decrease anthropic emissions of the heavy metals studied, particularly Cr and Pb.The Covid-19 epidemic is an opportunity to underline how prison health on the African continent remains a weak link of the prison system. Beyond the difficulties in caring for Covid-19 in detention, prison infirmaries, where they exist, are rarely integrated into the health system in practice. Administrations provide little for the vital needs of prisoners. Dietary deficiencies are frequent, skin diseases recurrent and prisoners are most often dependent on the financial means of their families or NGOs when it comes to access to health care. The social illegitimacy of the prison population and the reluctance of States to offer convicted prisoners what they do not guarantee to the general population are two arguments put forward to justify what amounts to necropolitics. At the same time, international actors working in prisons essentially target pathologies with epidemic potential, constrained by funding sources (UNAIDS, Global Fund) supporting population-wide health strategies. Here we would like to return to these two logics and develop an argument for a decompartmentalized approach to prison health. Beyond the recognition of individual health experience and epidemiological concerns, addressing prison health globally contributes to the restoration of prisoners’ dignity and rights by the State, a necessary condition for the maintenance of citizenship beyond confinement.

Pregnancy in schools is an obstacle to the development and education of young girls, especially in developing countries. The purpose of this study was to assess the frequency of pregnancies within a school setting and the profile of adolescent girls who have had the experience in Conakry, Guinea.

We conducted a cross-sectional study covering the period from January 1 to June 30, 2017 in 16 schools.

A total of 2,419 adolescent girls consented to participate in the study. The mean age was 16.48±0.04 years with extremes of 10 and 19 years. Students aged 15 to 19 (93.0%), those in college (53.3%) and single (69.8%) were the most likely to have been pregnant in school (P<0.05). The factors statistically significantly associated with the occurrence of teenage pregnancies in a school environment were age (Adjusted odds ratio (AOR)=1.5; 95%CI=1.3-1.7; P<0.001), school level (AOR=0.6; 95%CI=0.4-0.8; P=0.003 for Lycée), the place of residence (AOR=0.5; 95%CI=0.4-0.9; P=0.002 for Matam, AOR=0.4; 95%C sexual health information, knowledge of the benefits of family planning, and related difficulties access to sexual and reproductive health services.

The purpose of this article is to identify, the factors that would explain the adherence and use of MS and make recommendations for actions that would encourage the population to adhere more at the MS in the Ziguinchor region in Senegal.

The sample was concerned by 392patients selected by the quota method in the hospitals of the region. The data were processed and analyzed by the sphinx and stata software through the logistic regression method.

The factors that would explain the adherence and use of MS in the study area were perception, the presence of an elderly person in the household, confidence in MS, household size and the pyramid medical institution.

Faced with the increase in confirmed cases of COVID-19 in Senegal, particularly in the region of Dakar, epicenter of the disease, it is necessary to study the knowledge, attitudes and practices of the populations of the West and South districts on COVID-19.

A cross-sectional and analytical study was conducted from May9 to 30, 2020. A four-stage cluster survey was carried out at the level of the West and South districts. Univariate and multivariate analyzes were carried out using R3.4.4 software.

In total, 400people were surveyed. The mean age of those surveyed was 40.2 ± 14.7years and extremes of 18 and 82years. The male sex predominated in 66.5% of cases. People had good knowledge of the signs, transmission risks and prevention measures respectively in 4.7%; 3% and 47.8%. In total, 74% of the people surveyed respected the concept of “stay at home”. Wearing a mask and systematic hand washing with soap and water were noted among the people surveyed in 53.6% and 34.8% of cases, respectively. People who had good knowledge of preventive measures against COVID-19 wore the mask more (ORaj = 2.1 [1.2-3.5]) and washed their hands more with soap and water (ORaj = 1.9 [1.1-3.4]).

For an effective fight against this epidemic, it is important to strengthen risk communication with full community participation. This strategy must be coupled with actions aimed at making prevention means available to the benefit of the entire population.
