Mapping water sources and access to drinking water in the Lake Chad region of Cameroon: a cross-sectional study.

Introduction: people's access to quality water resources significantly improves their health. In Cameroon, access to drinking water is still limited and unequally distributed over the national territory with alarming figures in the northern part of the country. This study aimed to assess the distribution of water points and characterise water storage and treatment practices in households of the Lake Chad region of Cameroon.

Factors associated with full vaccination and zero vaccine dose in children aged 12-59 months in 6 health districts of Cameroon.

Background: Routine immunisation coverage in Cameroon is still below the target of the national Expanded Programme on Immunisation (EPI), with only 42% of children fully immunised according to Demographic and Health Survey (DHS) report in 2018. The objective of this study was to evaluate factors associated with full immunisation and zero-dose in Cameroonian children.

Methods: A two-stage cross-sectional cluster survey was conducted in Yaoundé in November 2021, targeting children aged 12-59 months.

Chronic diseases and mortality among hospitalised COVID-19 patients at Bafoussam Regional Hospital in the West region of Cameroon.

Reducing mortality among COVID-19 cases is a major challenge for most health systems worldwide. Estimating the risk of preexisting comorbidities on COVID-19 mortality may promote the importance of targeting at-risk populations to improve survival through primary and secondary prevention. This study was conducted to explore the contribution of exposure to some chronic diseases on the mortality of COVID-19.

Antioxidant, Anti-Inflammatory, and Digestive Enzymes Inhibition Activities of Hydro-Ethanolic Leaf and Bark Extracts of (K. Krause) Verdc.

hydro-ethanolic leaf extract (PHELE) and bark extract (PHEBE) were evaluated for antioxidant, anti-inflammatory, and inhibition of digestive enzymes activities. The antioxidant activity was characterized by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), total phenolic content (TPC), and total flavonoid content (TFC) assays. The anti-inflammatory activity was characterized by protein denaturation and antiproteinase tests, while the inhibition of the enzymes was assessed using -amylase, -glucosidase, lipase, and cholesterol esterase activities.

Urban malaria in sub-Saharan Africa: dynamic of the vectorial system and the entomological inoculation rate.

Sub-Saharan Africa is registering one of the highest urban population growth across the world. It is estimated that over 75% of the population in this region will be living in urban settings by 2050. However, it is not known how this rapid urbanization will affect vector populations and disease transmission.

Corrigendum to "Modeling, simulation and optimization of solid fuel bread ovens commonly used in developing countries" [Heliyon 7(2), (February 2021) Article e06184].

[This corrects the article DOI: 10.1016/j.heliyon.

Modeling, simulation and optimization of solid fuel bread ovens commonly used in developing countries.

In this work, we propose a mathematical model describing thermal behavior and heating process optimization of solid fuel bread ovens. Numerical simulation leads to temperature profiles of the oven. The design and implementation of an operating prototype permits us to obtain, with type K thermocouples, experimental temperature profiles in some points of the oven.

Psychological distress among health care professionals of the three COVID-19 most affected Regions in Cameroon: Prevalence and associated factors.

Objectives: The present study aimed to assess the prevalence of symptoms of anxiety and depression among health professionals in the three most affected regions in Cameroon.

Materials And Methods: The study was a descriptive cross-sectional type. Participants were health care professionals working in the three chosen regions of Cameroon.

Semen quality among men attending urology services in the Dschang Health District, west Cameroon: A retrospective study on 379 cases.

Background: Infertility is a common condition affecting at least 15% of couples worldwide, and male factors are involved in about half of this prevalence rate. In Cameroon, about 20%-40% of couples are the victims. However, the sperm characteristics of infertile men are yet to be described in the health districts in Cameroon for better management of male infertility.

The anti-shigellosis activity of the methanol extract of Picralima nitida on Shigella dysenteriae type I induced diarrhoea in rats.

Background: Picralima nitida Stapf (Apocynaceae) is a medicinal plant used traditionally in Cameroon to cure various ailments such as gastrointestinal disorders and dysentery. This study reports the in vitro and in vivo anti-shigellosis activity of the methanol extract of this plant on rats.

Methods: The antimicrobial activity of the extract against pathogenic strains was evaluated using the disc diffusion assay and broth microdilution method.
