Traditionally fermented maize starch, called ogi, is produced to prepare akpan, a yoghurt-like street food widely consumed in Benin. Current maize ogi production practices were compared to assess the impact of different processing technologies on the characteristics of the fermented product as a basis to determine best practices. Maize starch slurry samples were collected from processors in five municipalities in southern Benin and analysed before fermentation (starch samples) and after spontaneous fermentation (ogi samples)...

A Stakeholder engagement meeting on the implementation of post-discharge malaria chemoprevention (PDMC) in Benin, Kenya, Malawi, and Uganda was held in Nairobi, Kenya, on 27 September 2023. Representatives from the respective National Malaria Control Programmes, the World Health Organization (WHO) Geneva, Africa Regional and Kenya offices, research partners, non-governmental organizations, and the Medicines for Malaria Venture participated. PDMC was recommended by the WHO in June 2022 and involves provision of a full anti-malarial treatment course at regular intervals during the post-discharge period in children hospitalized with severe anaemia in areas of moderate-to-high malaria transmission...

BACKGROUND: Leptospirosis is a zoonotic disease. It is particularly prevalent in tropical countries and has major consequences for human and animal health. In Benin, the disease's epidemiology remains poorly understood, especially in livestock, for which data are lacking. OBJECTIVES: To characterise Leptospira seroprevalence and locally circulating serogroups in livestock from Cotonou and to estimate the prevalence of Leptospira renal carriage in cattle. METHODS: We conducted a cross-sectional study in February 2020 during which livestock were sampled at an abattoir and in an impoverished city district...

Phylloporia is a widespread genus of Hymenochaetales ( Basidiomycota ) with polyporoid basidiomata found mainly in the tropics. Species of Phylloporia are predominantly parasitic of woody plant hosts, while some species grow as saprotrophs. Data on the genus is still scarce for tropical Africa, where we expect a high diversity given the high plant diversity in this area. Two specimens of this genus were collected in Benin (West Africa) and analysed morphologically and phylogenetically based on a multigene dataset (ITS, LSU, EF1α )...

BACKGROUND: Dementia is a growing global health challenge, with significant socioeconomic implications. This study examined the informal care duration and related costs along with the total cost of care for older individuals with dementia in Benin, West Africa, providing insights into a region with limited dementia research. METHODS: We conducted a cost-of-illness study in Benin. Both hospital and community recruitments were used to enroll adults aged ≥ 60 years and their primary caregivers...

Smallholder households in developing countries often face challenges related to market access. Despite being proposed as a potential solution, cooperatives in the north of Benin have reportedly failed to effectively address this issue. The alternatives channels used by smallholder famers and the factors that influence their choices remain unclear. This paper adopts a mixed approach, combining qualitative analysis with quantitative methods, particularly the multivariate probit model, to investigate the distribution channels of maize used by farmers in the Kandi district of Benin...

MÉTHODES: Il s'agissait d'une étude transversale à caractère analytique. L'enquête s'est déroulée en octobre 2016 et a porté sur un échantillon de 270 sujets...

African swine fever (ASF) is a devastating disease of domestic pigs that has spread across the globe since its introduction into Georgia in 2007. The etiological agent is a large double-stranded DNA virus with a genome of 170 to 180 kb in length depending on the isolate. Much of the differences in genome length between isolates are due to variations in the copy number of five different multigene families that are encoded in repetitive regions that are towards the termini of the covalently closed ends of the genome...

OBJECTIVE: To determine the association between occupational factors, particularly psychosocial factors, and hypertension. DESIGN: Descriptive and analytical cross-sectional study using logistic multivariate regression. SETTING: Fifteen cotton ginning plants in Benin. PARTICIPANTS: Permanent and occasional workers in the cotton ginning industry. DATA COLLECTION: Data on sociodemographic, occupational, behavioural and clinical history characteristics were collected using a number of standardised, interviewer-administered questionnaires...

Vaccination is considered one of the solutions to the Coronavirus Disease 2019 (COVID-19) pandemic. However, a small proportion of the population were fully vaccinated in Benin (20.9%) and Senegal (7.6%) by December 2022. This study explores the determinants of intent to vaccinate. This was a cross-sectional, descriptive, and analytical study of 865 Beninese and 813 Senegalese aged 18 years and older. Marginal quota sampling by age, gender and region was adopted. Data collection, using a survey instrument based on the Random Digit Dialing method, was conducted from December 24, 2020, to January 16, 2021, in Senegal and from March 29 to May 14, 2021, in Benin...

BACKGROUND: Vegetation health (VH) is a powerful characteristic for forecasting malaria incidence in regions where the disease is prevalent. This study aims to determine how vegetation health affects the prevalence of malaria and create seasonal weather forecasts using NOAA/AVHRR environmental satellite data that can be substituted for malaria epidemic forecasts. METHODS: Weekly advanced very high-resolution radiometer (AVHRR) data were retrieved from the NOAA satellite website from 2009 to 2021...

BACKGROUND: Dyslipidemia is becoming prevalent in Africa, where malaria is endemic. Observational studies have documented the long-term protective effect of malaria on dyslipidemia; however, these study designs are prone to confounding. Therefore, we used Mendelian randomization (MR, a method robust to confounders and reverse causation) to determine the causal effect of severe malaria (SM) and the recurrence of non-severe malaria (RNM) on lipid traits. METHOD: We performed two-sample MR using genome wide association study (GWAS) summary statistics for recurrent non-severe malaria (RNM) from a Benin cohort (N = 775) and severe malaria from the MalariaGEN dataset (N = 17,000) and lipid traits from summary-level data of a meta-analyzed African lipid GWAS (MALG, N = 24,215) from the African Partnership for Chronic Disease Research (APCDR) (N = 13,612) and the Africa Wits-IN-DEPTH partnership for genomics studies (AWI-Gen) dataset (N = 10,603)...

BACKGROUND: Recently, bacterial endosymbiont, including Wolbachia and Microsporidia were found to limit the infection of Anopheles mosquitoes with Plasmodium falciparum. This study aimed to investigate the natural presence of key transmission-blocking endosymbionts in Anopheles gambiae and Anopheles coluzzii in Southern Benin. METHODS: The present study was conducted in seven communes (Cotonou, Porto-Novo, Aguégués, Ifangni, Pobè Athiémé, and Grand-Popo) of Southern Benin...

Purpose: First healthcare actors in neurological diseases management, General Practitioners (GPs) still limited in the assessment of Peripheral Neuropathies (PN). This study assesses the knowledge, attitudes, practices (KAP) of GPs on PN in Benin in 2021 and identifying associated factors to low KAP. Materials and methods: It was a cross-sectional study conducted from 20 November 2020 to 30 June 2021 which included GPs registered in the National Order of Physicians in Benin and interns in last year of medical studies (MS)...

Aedes mosquitoes are the main vectors of arboviruses in Benin. Cases of dengue have been reported in Benin with all four serotypes of the virus actively circulating in this region. Some agricultural settings are known to harbor Aedes vectors responsible for the transmission of arboviruses. The massive use of certain insecticides in agricultural settings has probably contributed to insecticide resistance in these vectors. In Benin, the susceptibility of arbovirus vectors to insecticides is poorly studied. In addition, the distribution of Wolbachia spp...

BACKGROUND: Indoor residual spraying (IRS) was first implemented in the Atacora department, Benin from 2011 to 2012 using bendiocarb (carbamate) followed by annual spraying with pirimiphos-methyl (organophosphate) from 2013 to 2018. Before and after IRS implementation in Atacora, standard pyrethroid insecticide-treated bed nets were the main method of vector control in the area. This study investigated the knockdown resistance (kdr) gene (L1014F) and the acetylcholinesterase (ace-1) gene (G119S), before and during IRS implementation, and 4-years after IRS withdrawal from Atacora...

One of the major concerns for developing countries is improving the use of health services by the general population, and in particular, maternal and child health services. This concern reflects the Sustainable Development Goals 3, which aim to ensure the health and well-being of all by improving reproductive health, and especially maternal and child health. This study analyses the extent to which modern energies improve women's empowerment and the demand for maternal health services in a low income country...

UNLABELLED: The classical lineage of Mycobacterium ulcerans is the most prevalent clonal group associated with Buruli ulcer in humans. Its reservoir is strongly associated with the environment. We analyzed together 1,045 isolates collected from 13 countries on two continents to define the evolutionary history and population dynamics of this lineage. We confirm that this lineage spread over 7,000 years from Australia to Africa with the emergence of outbreaks in distinct waves in the 18th and 19th centuries...

BACKGROUND: Food and nutrition notion among schoolchildren in Benin is still less documented. Few studies have examined the determinants of food and nutrition among schoolchildren while others have attempted to link knowledge, attitudes and practices to diet. The present study aims to evaluate food and nutrition knowledge, attitudes and practices among schoolchildren enrolled in public primary schools canteens in Cotonou and its surroundings. METHODS: A diagnostic study was conducted in twelve public primary schools with canteens...

Nigeria sits at the crossroads of West and Central Africa; two increasingly critical regions for global health security. To strengthen cross-border collaboration for health security between its neighbors from West and Central Africa, the Federal Ministry of Health, Nigeria through the public health authority at the Points of Entry-Port Health Services, led the design of a multi-lateral framework for cross-border collaboration between Nigeria, the Republic of Benin, the Republic of Chad, the Republic of Cameroon and the Republic of Niger...
