Strengthening Maternal Death Surveillance Systems for Evidence-Based Decision Making in Sub-Saharan Africa: The Case of the Center Region in Cameroon.

Background: The article seeks to document the experience of implementing Maternal Death Surveillance and Response (MDSR) in the Center Region of Cameroon. The paper raises awareness on the need for implementing MDSR, shares progress and lessons learned and reflects on the implications for public health practice.

Methods: A desk research involving the collection and analysis of secondary data using tables with specific themes in excel, following the review of existing resources at the Regional Delegation of Public Health-Center from the year 2016 to 2019.

Geochemical provenance and spatial distribution of fluoride in groundwater of Mayo Tsanaga River Basin, Far North Region, Cameroon: implications for incidence of fluorosis and optimal consumption dose.

The 500,000 inhabitants of Mayo Tsanaga River Basin are vulnerable to a "silent" fluorosis from groundwater consumption. For the first time, the groundwater is investigated for the purpose of identifying the provenance of fluoride and estimating an optimal dose of fluoride in the study area. Based on the fluoride content of groundwater, fluorine and major oxides abundances in rocks from the study area, mean annual atmospheric temperature, and on-site diagnosis of fluorosis in children, the following results and conclusions are obtained: Fluoride concentration in groundwater ranges from 0.
