Dynamics of submicroscopic and microscopic asymptomatic malaria infection and associated factors: A longitudinal study in South Benin.

Introduction: Asymptomatic malaria infection is now recognized as a potential threat to malaria control. However, its prevalence and its dynamics are poorly documented especially in a perennial context of high seasonal transmission. A longitudinal study was conducted in southern Benin to investigate the dynamics of asymptomatic malaria infection and to identify factors influencing it.

The effect of next-generation, dual-active-ingredient, long-lasting insecticidal net deployment on insecticide resistance in malaria vectors in Benin: results of a 3-year, three-arm, cluster-randomised, controlled trial.

Background: Insecticide resistance among malaria vector species now occurs in 84 malaria-endemic countries and territories worldwide. Novel vector-control interventions, including long-lasting insecticidal nets (LLINs) that incorporate new active ingredients with distinct modes of action, are urgently needed to delay the evolution and spread of resistance and to alleviate reversals in malaria-control gains. We aimed to assess the longitudinal effect of two dual-active-ingredient LLINs on insecticide resistance during a cluster-randomised, controlled trial in Benin.

Enteric methane emissions from zebu cattle are influenced by seasonal variations in rangeland fodder quality and intake.

Rangeland fodder resources used to feed ruminants in the Sahel decline considerably in both quantity and quality from the wet to dry seasons. While it is widely assumed worldwide that this seasonality of fodder supply impacts intake levels and therefore enteric methane (eCH) emissions, there are very few references based on in vivo measurements of eCH in this region. The purpose of this study was to test the assumption that the seasonality of fodder supply impacts intake levels and consequently eCH in ruminants.

Sustainable ruminant nutrition in West Africa by in vitro characterization of cashew apple by-products.

Cashew trees ( L.) are planted for primarily their nuts, but they also generate apples which are mostly thrown away due to their astringent taste. The current study aimed to explore the possible utilization of cashew apple by-products (CABP) in West Africa as an alternative feedstuff for small ruminants' nutrition.

Cross-cultural adaptation and validation of a French version of the Measure of Stroke Environment (MOSE) in stroke survivors in Sub-Saharan Africa.

Purpose: To investigate the psychometric properties of the MOSE-Benin, a French-language version of the Measure of Stroke Environment (MOSE) for Sub-Saharan Africa.

Materials And Methods: The original English version of the MOSE has been translated into French following the guidelines for cross-cultural adaptation. The resulting questionnaire (MOSE-Benin) was administered to a convenience sample of participants recruited in Benin, a French-speaking country.

Non-adherence to hypertensive drugs is a barrier to controlling blood pressure and decreases hypertensive patients' quality of life. The aim of this study was to determine the prevalence of non-adherence to hypertensive drugs among hypertensive patients treated at Marrakech's primary health care facilities. A cross-sectional survey of 922 hypertensive patients treated at Marrakech's primary health care facilities for arterial hypertension was conducted between 2021 and 2022.

Image cropping for malaria parasite detection on heterogeneous data.

Malaria is a deadly disease of significant concern for the international community. It is an infectious disease caused by a Plasmodium spp. parasite and transmitted by the bite of an infected female Anopheles mosquito.

Diversity and ecological niche model of malaria vector and non-vector mosquito species in Covè, Ouinhi, and Zangnanado, Southern Benin.

The present study aimed to assess mosquito species diversity, distribution, and ecological preferences in the Covè, Ouinhi, and Zangnanado communes, Southern Benin. Such information is critical to understand mosquito bio-ecology and to focus control efforts in high-risk areas for vector-borne diseases. Mosquito collections occurred quarterly in 60 clusters between June 2020 and April 2021, using human landing catches.

Parataxonomy and diversity of local varieties of taro ( (L.) Schott) and macabo ( (L.) Schott) grown in Benin (West Africa).

Taro and macabo are plants with high food, medicinal and economic value, but are under-utilized in Benin. The aim of this study was to identify local varieties of taro and macabo grown in Benin, with their vernacular names, farmers' recognition criteria and distribution. Data were collected between May 2021 and May 2023, through interviews using semi-structured questionnaires.

Population genetic structure of Schistosoma bovis and S. curassoni collected from cattle in Mali.

Schistosomiasis is of medical and veterinary importance. Despite the critical situation of schistosomiasis in sub-Saharan Africa, few molecular epidemiological studies have been carried out to determine the role of animals in its transmission. In Mali, it has been over three decades since the last molecular study of animal schistosomes was carried out.

Unraveling the quality of implementation of sexual and reproductive health projects among adolescents and youths in low-income regions: a case study of the JADES 2 project in Niger in 2021.

Introduction: many young people globally grapple with early pregnancies and sexually transmitted diseases (STD), especially in regions like Africa and particularly Niger due to high poverty rates. Various sexual and reproductive health (SRH) projects aim to address these challenges. This study evaluated the JADES 2 project's implementation of SRH services provided focusing on the quality of these services in Niger in 2021.

[Coverage, mapping and barriers to complete vaccination for age among children under 5 years in 2021: case of Adjara-Hounvè and Ahouicodji villages in southern Benin].

Efficacy of pyrethroid-pyriproxyfen and pyrethroid-chlorfenapyr nets on entomological indicators of malaria transmission: third year of a randomised controlled trial in Benin.

The present cluster-randomised control trial aims to assess the entomological efficacy of pyrethroid-pyriproxyfen and pyrethroid-chlorfenapyr LLINs compared to the standard pyrethroid-only LLINs, in their third year of community usage. Adult mosquito collections were performed every 3 months, in 4 randomly selected houses in each of the 60 trial clusters, using human landing catches. Adult mosquitoes were morphologically identified and Anopheles vectors were molecularly speciated and screened for the presence of the L1014F kdr mutation using PCR.

Metaproteomic analysis of King Ghezo tomb wall (Abomey, Benin) confirms 19th century voodoo sacrifices.

The palace of King Ghezo in Abomey, capital of the ancient kingdom of Dahomey (present-day Benin), houses two sacred huts which are specific funerary structures. It is claimed that the binder in their walls is made of human blood. In the study presented here, we conceived an original strategy to analyze the proteins present on minute amounts of the cladding sampled from the inner facade of the cenotaph wall and establish their origin.
