Participatory selection of Hibiscus sabdariffa L. landraces in Burkina Faso: characteristics of interest and selection criteria for leaves
Clémence Zerbo, Romaric Kiswendsida Nanema, Zakaria Kiebre, Mariam Kiebre, Fanta Reine Sheirita Tietiambou, Hamid El Bilali, Filippo Acasto, Jacques Nanema and Mahamadou SawadogoIntroduction: Hibiscus sabdariffa L. is an economically important and widely adopted crop in Burkina Faso. Yet its production is constrained by the lack of improved, locally adapted varieties. This study used a participatory variety selection approach to identify preferred landraces and selection criteria across two agroecological zones: Sudanian and Sudano-Sahelian.
Methods: The evaluation of landraces/accessions was carried out using an ordinal rating system, assigning scores ranging from 9 (most preferred accession), through 7 (very interesting), 5 (moderately interesting), 3 (less interesting), to 1 (least interesting). Landraces considered undesirable were specifically evaluated using negative scores of −5, −3, and −1, reflecting the degree of rejection expressed by the participants.
Results: Participatory selection involved 126 stakeholders (75.4% women), including producers...

Facteurs associés au dépistage des cancers du col de l’utérus et du sein chez les femmes de 15-49 ans au Burkina Faso
Hervé BassingaContexte : Lorsque l’on considère les maladies non transmissibles (MNT), les cancers du col de l’utérus et du sein figurent parmi les principales causes de morbidité et de mortalité féminine au Burkina Faso. Bien que le dépistage précoce constitue une stratégie efficace pour améliorer la survie et la qualité de vie des femmes, les taux de recours y demeurent faibles. Cette étude explore les facteurs associés au dépistage du cancer du col de l’utérus et du sein chez les femmes burkinabè âgées de 15 à 49 ans.Données et méthodes:Cette recherche a combiné une analyse descriptive des taux de dépistage et une régression logistique binaire pour identifier les facteurs influençant le recours au dépistage des deux types de cancer à partir des données de l’enquête démographique et de santé (EDS) réalisée en 2021. L’analyse a porté sur un échantillon de 17659 femmes â...

Fuelling energy poverty? Evidence on the role of deforestation in developing countries
Windbeneti Arnaud Zahonogo, Relwendé SawadogoEnergy poverty remains a critical development challenge in low- and middle-income countries, central to achieving Sustainable Development Goal 7 (SDG7). This study investigates the causal impact of deforestation on energy poverty, focusing on two key dimensions: access to electricity and access to clean cooking fuels. Using a panel of 95 developing countries from 2000 to 2023, we employ robust econometric techniques, including ordinary least squares (OLS), two-stage least squares (2SLS), and smoothed instrumental variable quantile regression (SIVQR), to account for endogeneity and distributional heterogeneity. The results consistently show that deforestation significantly worsens energy poverty, particularly in more deprived contexts, by reducing access to clean fuels and electricity. These findings remain robust across alternative deforestation measures and model specifications. Further...

Premières caractérisations morpho typologiques de la céramique archéologiques des enceintes et structures en pierres, sud-ouest du Burkina Faso
Simporé LassinaLes enceintes et structures en pierre sont les principaux vestiges archéologiques connus dans l’espace géoculturel appelé abusivement ‘pays lobi’ au Burkina Faso, Afrique occidentale.
Depuis les premières publications à leur sujet au début du vingtième siècle, leur architecture a été l’aspect matériel le plus traité. Cette focalisation sur les aspects architecturaux se justifierait par leur caractère atypique pour la région d’une part et leur facilité d’accès à travers les affleurements de murs en surface,
d’autre part. En revanche, le mobilier archéologique, notamment céramique a été négligé, même si plusieurs auteurs y font référence. À l’avènement des fouilles archéologiques au début des années 2000, la production céramique s’est avérée majoritaire dans les corpus du mobilier mis au jour lors des différentes
investigations. Au regard du potentiel de la céramique pour appréhender fa...

EFFET DES APPELS TÉLÉPHONIQUES SUR LES TAUX DE SUIVI DE LA COHORTE CHAIN-BURKINA FASO, DE 2018 À 2020
Abdoulaye Hama DIALLO1,2,3, Jocelyne Valérie GARE2, Lamoussa TRAORE4, Seydou OUATTARA2,3, Blaise GNOUMOU1, Roseline Maïmouna BAMOUNI1, Issaka OUEDRAOGO4Le taux de déperdition des participants dans une cohorte
prospective est une préoccupation majeure pour les investigateurs,
compte tenu de son impact sur la validité interne des enquêtes. Notre
étude avait pour objectif d’évaluer l’effet des appels téléphoniques
sur les taux de suivi d’une cohorte de nourrissons au Burkina Faso.
La cohorte du Projet CHAIN-BURKINA FASO était constituée de
nourrissons âgés de 2 à 23 mois, hospitalisés pour morbidité aiguë
et suivis pendant 6 mois après l’hospitalisation respectivement à
J45, J90 et J180. Une régression binomiale avec calcul de risque
relatif (RR) a permis d’estimer l’effet des appels téléphoniques sur
l’effectivité de la visite de suivi planifiée. Au total, 415 enfants
hospitalisés et sortis vivants ont été inclus dans les analyses. Les
taux de suivi étaient respectivement de 93,6% (IC95%= [92,6 - 94,4])
à J45 ; 89,1% (IC95%=...

Chronic hepatitis B virus (HBV) infection is a leading cause of hepatocellular carcinoma (HCC), yet reliable biomarkers for early detection and risk stratification remain limited. This study aimed to identify plasma proteins associated with disease progression from chronic HBV infection to HCC.
Methods
Plasma proteomic profiling was conducted using high-resolution LC–MS/MS on samples from healthy controls, chronic HBV carriers, patients with cirrhosis, and individuals with HBV-associated HCC. Differentially expressed proteins were identified through bioinformatics analysis, and protein–protein interaction networks were reconstructed to assess functional relevance.
Results
Eight proteins displayed distinct, stage-specific expression patterns along the disease continuum. ICAM1, TIMP1, and IGFBP7 were progressively upregulated, reflecting roles in inflammation, fibrosis,...

Watershed-Based Approaches for Sustainable Agricultural Ecosystem Management in Burkina Faso
Nikiema Sanata, Compaoré HyacyntheAgriculture plays a pivotal role in the socio-economic development of Burkina Faso, employing a large proportion of the population and contributing significantly to national GDP. However, this sector faces critical challenges, notably rapid soil degradation, declining fertility and the increasing vulnerability of farming systems to climate variability. To mitigate these issues, soil and water conservation (SWC/SDR) techniques have been widely promoted and implemented at the individual farm level. While these practices have proven beneficial locally, they often fail to capture broader landscape-scale benefits. In contrast, watershed-based approaches integrate land and water management across multiple plots, generating substantial positive externalities, including reduced upstream runoff, diminished downstream erosion and enhanced ecosystem services. This study investigates
farmers' accep...

Transfusion Safety in Burkina Faso: Molecular and Serological Characterization of VAH and VHB and Coinfections in Blood Donors at the Regional Blood Transfusion Center of Koudougou, Nando Region
Tao, I., Thio, L.M.E., Bado, P., Traore, I.M.A., Sama, W.A., Séni, N., Ouattara, A.K., Compaore, R.T., Bazié, V.J.T.E., Yelemkoure, T.E., Kiba, A., Yonli, A.T., Djigma, F. and Simpore, J.Introduction: Hepatitis A virus (HAV) and hepatitis B virus (HBV) infections represent significant public health challenges in sub-Saharan Africa, including Burkina Faso. HAV is the most symptomatic viral hepatitis, while HBV is the most endemic and can lead to severe complications such as cirrhosis and hepatocellular carcinoma (HCC). HAV is an RNA virus belonging to the Picornaviridae family, whereas HBV is a DNA virus of the Hepadnaviridae family. Despite the health burden of HAV, limited data are available on its prevalence in Burkina Faso. Although more information exists on HBV, the introduction of the HBV vaccine into the Expanded Program on Immunization (EPI) and ongoing awareness campaigns necessitate regular updates on its epidemiological status. This study aimed to conduct serological and molecular PCR-based diagnosis of HAV and HBV among blood donors at the Regional Blood Tran...

Identification of Novel TERT Promoter Mutations in Chronic Hepatitis B-Induced HCC Patients in Burkina Faso
Zongo, V.S., Zhou, Y.M., Djigma, F.W., Roamba, E., Yonli, A.T., Sorgho, A.P., Barro, O., Somda, S.K., Compaore, T.R., Sanou, M., Martinson, J.J., Traore, L., Chamcheu, J.C., Zongo, J.K., Lompo, O.M., Roberts, L.R., Borad, M.J., Nagalo, B.M. and Simpore, J.K.Introduction: Hepatocellular carcinoma (HCC) is one of the serious complications of chronic hepatitis B virus (HBV) infection and constitutes a major global public health problem. Several factors contribute to the development of this cancer, the genetic aspect of which is linked to mutations in genes such as the human telomerase reverse transcriptase (TERT) gene. This gene plays a crucial role in maintaining telomeres. Genetic alterations in this gene can result in a defect in the continuous synthesis of telomeres, reducing the sensitivity of cells to apoptosis. Method: This was a descriptive study in which 97 patients were enrolled. TERT promoter mutations were characterized using Sanger sequencing technology and the functionality of the mutations identified was validated using cell culture techniques. Results: Our study showed that patients with unknown etiology status were mainly affe...
