Enhancement of the geological mapping in weathered plutonic and metamorphic rocks areas using village water supply wells data (lithology and hydrochemistry).

In weathered plutonic and metamorphic rocks areas, because rock outcrops are rare due to the extensive regolith cover, geological mapping is largely based on the interpretation of airborne data and imagery (aerial photographs, satellite images, airborne geophysics when available, etc.). In the sub-Saharan Africa, numerous village water supply campaigns were performed during the last 40 years.

Supplementation of laying hens' feed with Schizochytrium powder and its effect on physical and chemical properties of eggs.

Exploring the sexual and reproductive health knowledge, practices and needs of adolescents living with perinatally acquired HIV in Côte d'Ivoire: a qualitative study.

Introduction: Adolescents face unique challenges in accessing appropriate information and services regarding sexuality and reproductive health (SRH). This poor access can lead to sexual behaviours that could put them at risk of unintended pregnancies and sexually transmitted infections. Adolescents living with HIV (ALHIV) have specific SRH needs that remain unmet.

Assessment of mycotoxins in infant flour and their decontamination in raw material during production processes in Ouagadougou.

The infant flours produced in Burkina Faso are essentially a mixture of cereals and legumes. These raw materials are frequently contaminated with mycotoxins which pose a huge food safety and public health threat. The objective of this study was to determine mycotoxin levels in raw materials and infant flours in Ouagadougou and to investigate the impact of decontamination on the raw materials used in infant flour production.

Characterization of human exposure to Anopheles and Aedes bites using antibody-based biomarkers in rural zone of Cameroon.

Malaria and Aedes-borne diseases remain major causes of mortality, morbidity, and disability in most developing countries. Surveillance of transmission patterns associated with vector control remains strategic for combating these diseases. Due to the limitions of current surveillance tools used to assess human exposure to mosquito bites, human antibody (Ab) responses to salivary peptides from Anopheles (gSG6-P1) and Aedes (Nterm-34kDa) are increasingly being used to measure direct human-Anopheles or Aedes contact.

biopesticide overcomes insecticide resistance in malaria vector mosquitoes.

Vector mosquito control is an integral part of malaria control. The global emergence of insecticide resistance in malaria-transmitting has become an impediment and has created an urgent need for novel mosquito control approaches. Here, we show that a biopesticide derived from the soil-dwelling bacterium sp.

Contraceptive Care Visit Objectives and Outcomes: Evidence From Burkina Faso, Pakistan, and Tanzania.

Globally, care experiences of the growing population of contraceptive users are not well-understood. We leverage a large client dataset (n = 71,602) from three countries (Burkina Faso, Pakistan, and Tanzania) to characterize contraceptive services sought (visit objective and method preference), assess whether these visit objectives were met and for whom, and explore if visit objective fulfillment was associated with care quality. Most people in all three countries said they were seeking to continue their current method or adopt a method for the first time.

Background: Diabetes is a significant health concern in sub-Saharan Africa, emphasizing the importance of assessing the health literacy and eHealth skills of hospitalized patients with diabetes. This study evaluated the health literacy and eHealth literacy of patients with diabetes at Donka Hospital in Guinea and Sanou Sourou Hospital in Burkina Faso, providing insights for targeted interventions and mobile health (mHealth) solutions to improve self-management and treatment outcomes.

Objective: The aim of this study is to evaluate the levels of health literacy and eHealth literacy among patients at Sanou Sourou Hospital in Burkina Faso and Donka Hospital in Guinea.

Three years of insecticide resistance evolution and associated mechanisms in Aedes aegypti populations of Ouagadougou, Burkina Faso.

Background: Resistance to insecticides is spreading among populations of Aedes aegypti, the primary vector of important human arboviruses. The escalating insecticide resistance poses a significant threat to dengue vector control, with an expanding number of countries affected by the disease. To gain a deeper insight into the evolution of insecticide resistance, it is essential to have longitudinal surveillance results, which are currently lacking, particularly from African Ae.

Turmeric () is an herbaceous plant that contains a phytochemical which is bright yellow and is known as curcumin. Turmeric, a member of Zingiberaceae family, has extensive application worldwide due to its beneficial medicinal attributes and is extensively used as a medicinal plant. Most people use turmeric as a spice, and it is a chief source of polyphenol curcumin.

Costing curative outpatient care for the poorest in Burkina Faso: informing universal health coverage and leaving no one behind.

Introduction: The poorest in Burkina Faso face numerous barriers to healthcare access, including financial and geographic obstacles, as well as a high burden of chronic conditions and multimorbidity. This study estimates the average cost of providing curative outpatient consultations at first-level healthcare facilities to the poorest in Burkina Faso. It also estimates the budgetary impact of scaling up free access to these services nationwide.

Facilitators and challenges in collaboration between public health units and faith-based organizations to promote COVID-19 vaccine confidence in Ontario.

Background: Equitable access to vaccination remains a concern, particularly among population groups made structurally vulnerable. These population groups reflect the diversity of communities that are confronted with structural barriers caused by systemic racism and oppression and result in them experiencing suffer disadvantage and discrimination based on citizenship, race, ethnicity, ancestry, religion, spiritual beliefs, and/or gender identity. In Canada, Ontario public health units (PHUs) engage with faith-based organizations (FBOs) to improve vaccine confidence among populations made structurally vulnerable.

Rotavirus vaccine effectiveness stratified by national-level characteristics: an introduction to the 24-country MNSSTER-V Project, 2007-2023.

Background: Rotavirus vaccines are moderately protective against illness in high mortality settings compared with low mortality settings. Vaccine effectiveness (VE) evaluations may clarify our understanding of these disparities, but estimates among key subpopulations and against rare outcomes are not available in many analyses due to sample size. We combined 25 datasets from test-negative design case-control evaluations in 24 countries that enrolled children with medically-attended diarrhea, laboratory-confirmed rotavirus stool testing, and documented vaccination status.

World Health Organization African Region national heads of units of diagnostics and laboratory services meetings proceedings.

Background: In the World Health Organization (WHO) African Region, many cases of serious and preventable diseases remain unmanaged because appropriate and good quality diagnostic support is not available at all levels within countries' health systems. Diagnostic and laboratory services influence the efficiency and effectiveness of both clinical and public health functions, including diagnosis, treatment, health promotion, disease prevention, surveillance and response, and research. Essential to global health security, these services are vital to decision-making processes by clinicians, epidemiologists, public health specialists, and health policymakers.

Systemic biological mechanisms underpin poor post-discharge growth among severely wasted children with HIV.

In sub-Saharan Africa, children with severe malnutrition (SM) and HIV have substantially worse outcomes than children with SM alone, facing higher mortality risk and impaired nutritional recovery post-hospitalisation. Biological mechanisms underpinning this risk remain incompletely understood. This case-control study nested within the CHAIN cohort in Kenya, Uganda, Malawi, and Burkina Faso examined effect of HIV on six months post-discharge growth among children with SM and those at risk of malnutrition, assessed proteomic signatures associated with HIV in these children, and investigated how these systemic processes impact post-discharge growth in children with SM.

Impact of switching to a dolutegravir-based regimen on body weight changes: insights from West African adult HIV cohorts.

Introduction: Adverse metabolic effects related to dolutegravir (DTG) are increasingly reported as countries are adopting DTG-based regimens as first-line antiretroviral therapy (ART), but there is limited data from sub-Saharan Africa. We explored changes in body weight pre- and post-switch to a DTG-based regimen and assessed the association between DTG switch and significant weight gain (SWG) defined as a ≥10% increase over a 12-month period in people living with HIV (PLHIV) on ART in West Africa.

Methods: We first included all PLHIV followed in the IeDEA West Africa cohorts between January 2017 and June 2021, with a documented switch to DTG during 2019-2021 and in care ≥36 months at the day of switch.
