White matter alterations are increasingly implicated in neurological diseases and their progression. International-scale studies use diffusion-weighted magnetic resonance imaging (DW-MRI) to qualitatively identify changes in white matter microstructure and connectivity. Yet, quantitative analysis of DW-MRI data is hindered by inconsistencies stemming from varying acquisition protocols.

Article Synopsis
  • Trypanosome parasites are responsible for African animal trypanosomosis, a serious disease affecting livestock in sub-Saharan Africa, and interact directly with the host's immune system.
  • Understanding the immune response in cattle, which are significantly impacted by this disease, is essential for developing effective control strategies.
  • This review highlights the current state of knowledge on bovine immune responses to trypanosomosis, including infection processes, trypanotolerance, and key immune regulatory mechanisms, while also identifying critical areas that need more research.

Article Synopsis
  • An adapted in vitro pharmacology profiling panel (APPP) was created to evaluate the effects of 129 cosmetic chemicals, including both traditional pharmaceutical targets and additional targets related to systemic toxicities.
  • The study demonstrated strong internal data consistency, with reproducible results across different testing concentrations and compatibility with existing ToxCast and drug excipient data.
  • The findings highlight how this panel can aid in risk assessments for cosmetic chemicals without the need for new animal testing, supported by case studies and discussions of new methodologies.

In Burkina Faso, several investigations have raised suspicions that hospital liquid effluents are the source of contaminants in porbeagle-culture products and surface water in urban and peri-urban areas. This study aimed to evaluate the hygienic quality of hospital liquid effluents discharged into nature by the UHC Bogodogo (UHC-BOG), Yalgado Ouédraogo (UHC-YO), and the WWTS of Kossodo (WWTS-KOS). Thus, 15 samples of liquid effluents (five per site) discharged into nature were collected.

Staphylococcus aureus is a pathogen with high epidemic potential frequently involved in nosocomials and communities infections. The pathogenicity of Staphylococcus aureus is due to both its ability to resist antibiotics and to Produce toxins. This work aims at studying the resistance and Molecular Epidemiology of Staphylococcus aureus.

Background: Respiratory diseases have been associated with the exposure of populations to some environmental pollutants such as pesticides. To assess effects of pesticides on farmers' respiratory health, this study aimed to evaluate the pulmonary function of cotton farmers exposed to synthetic and natural pesticides in the Central-West region of Burkina Faso.

Methods: A cross-sectional study was conducted from June to July 2022 among 281 conventional and 189 organic cotton farmers.

Objective: This study aimed to investigate whether Otto Kuntze organic and aqueous extracts are able to control seizures induced by pentylenetetrazol (PTZ) in mice based on flavonoid fingerprints and alkaloidal contents.

Materials And Methods: Ethanolic extract and decoction-derived fractions from roots, leaves, and stems were subjected to chromatographic fingerprinting using AlCl and screening for their antiseizure effects using PTZ-induced acute seizure model. From the fractions that showed potent bioactivities, plausible antiseizure alkaloids were isolated using thin layer chromatography, and their structures were elucidated using H NMR, 2D NMR, C NMR, and FAB-HR ( or ).

Background: Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making of national programs to control, or eliminate these both diseases. In areas where both diseases prevalence is low, a large number of mosquitoes need to be sampled to determine vectors infection rate. To do this, efficient mosquito collection methods must be used.

Background: A 20-valent pneumococcal conjugate vaccine (PCV20), containing 13-valent PCV (PCV13) components and 7 additional polysaccharide conjugates, was developed to extend protection for pneumococcal disease. This phase 3 study assessed the safety and immunogenicity of PCV20 in children.

Methods: In this single-arm study, children (≥15 months-<18 years of age) received 1 dose of PCV20.

Article Synopsis
  • The study highlights that dengue fever is a growing health issue in Burkina Faso, especially in the Central Region, and it focuses on understanding its prevalence among adult febrile patients.
  • Researchers conducted a thorough survey involving 637 patients, finding a dengue prevalence of 8.16%, with significant symptoms including vomiting and myalgia linked to specific dengue markers.
  • Key findings indicate that living or spending time in the Arrondissement 4 area increases the likelihood of contracting dengue, while awareness of the disease appears to reduce its odds among participants.

Host age variation is a striking source of heterogeneity that can shape the evolution and transmission dynamic of pathogens. Compared with vertebrate systems, our understanding of the impact of host age on invertebrate-pathogen interactions remains limited. We examined the influence of mosquito age on key life-history traits driving human malaria transmission.

Tsetse flies (Diptera: Glossinidae) are vectors of the tropical neglected diseases sleeping sickness in humans and nagana in animals. The elimination of these diseases is linked to control of the vector. The sterile insect technique (SIT) is an environment-friendly method that has been shown to be effective when applied in an area-wide integrated pest management approach.

Background: Mosquitoes (Diptera: Culicidae) can have a significant negative impact on human health. The urbanization of natural environments and their conversion for agricultural use, as well as human population growth, may affect mosquito populations and increase the risk of emerging or re-emerging mosquito-borne diseases. We report on the variety and number of adult mosquitoes found in four environments with varying degrees of human impact (rural, urban, rice fields, and forest) located in a savannah zone of West Africa.

Introduction: General anaesthesia and surgery increase morbidity and mortality in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) who are not known to have OSAHS and therefore not treated before surgery. The objective of this study is to evaluate the risk of OSAHS using the STOP-BANG questionnaire (SBQ) in patients undergoing general anaesthesia in Burkina Faso.

Material And Method: This is a cross-sectional study concerning patients having received pre-anaesthetic consultation from 1st July 2020 to 30th June 2021.

Many New Approach Methodologies (NAMs) have been developed for the safety assessment of new ingredients. Research into reproductive toxicity and teratogenicity is a particularly high priority, especially given their mechanistic complexity. Forty-six non-teratogenic and 39 teratogenic chemicals were screened for teratogenic potential using the in silico DART model from the OECD QSAR Toolbox; the devTox quickPredict™ (devTox assay) test and the Zebrafish Embryotoxicity Test (ZET).

In the fight against malaria, transmission blocking interventions (TBIs) such as transmission blocking vaccines or drugs, are promising approaches to complement conventional tools. They aim to prevent the infection of vectors and thereby reduce the subsequent exposure of a human population to infectious mosquitoes. The effectiveness of these approaches has been shown to depend on the initial intensity of infection in mosquitoes, often measured as the mean number of oocysts resulting from an infectious blood meal in absence of intervention.
