Impact des Déchets Plastiques sur les Pâturages Urbains et Péri-urbains de la Ville de Dori, Région du Sahel : cas des Ruminants Domestiques

Les pâturages naturels constituent la principale ressource alimentaire des ruminants dans la zone urbaine et péri-urbaine de Dori. Ces pâturages naturels sont non seulement insuffisants pour les animaux mais aussi pollués par les sachets plastiques. Cette insuffisance alimentaire (quantitative et qualitative) amène les ruminants à ingérer des sachets plastiques. Notre étude avait pour objectif général d’étudier la prévalence de l’ingestion des sachets plastiques chez les ruminants (bovins, caprins et ovins). Elle s’est déroulée de février à juin 2021 par une collecte aléatoire de données à l’abattoir sur 600 échantillons de ruminants domestiques : 200 bovins, 200 caprins et 200 ovins. Nos résultats ont révélé que la prévalence de l’ingestion des sachets n’est pas liée à l’espèce: 31,5% chez les ovins, 30% chez les bovins et 23% chez les caprins (p = 0,131). Cette prévalence n’est pas également liée au sexe: 30% chez les femelles contre 26% chez les mâles (p = 0,379). Par ailleurs, les poids des sachets ingérés variaient significativement d’une espèce à l’autre (p < 0,001). Ainsi les bovins et ovins avaient tendance à en consommer plus que les caprins (p < 0,05). Les poids vifs et carcasses des animaux ayant ingérés des sachets plastiques sont sensiblement égaux à ceux qui n’en ont pas ingérés. Notre étude suggère que des dispositions particulières soient prises, notamment l’élevage en stabulation et la sensibilisation à l’usage et gestion des sachets dans les villes.   Natural pastures are the main alimentary resource for ruminants in the urban and peri-urban area of Dori. These natural pastures are not only insufficient for the animals but also polluted by plastic bags. This food insufficiency (quantitative and qualitative) leads ruminants to ingest plastic bags. The general objective of our study was to investigate the prevalence of plastic bag ingestion in ruminants (cattle, goats and sheep). It was conducted from February to June 2021 through random data collection at the abattoir on 600 samples of domestic ruminants: 200 cattle, 200 goats and 200 sheep. Our results revealed that the prevalence of plastic ingestion is not related to species: 31.5% in sheep, 30% in cattle and 23% in goats (p = 0.131). This prevalence was also not linked to sex: 30% in females versus 26% in males (p = 0.379). Furthermore, the weights of the plastic bags ingested varied significantly between species (p < 0.001). Cattle and sheep tended to consume more than goats (p < 0.05). The live and carcass weights of animals that ingested plastic bags were approximately equal to those that did not. Our study suggests that special measures should be taken, including stall breeding and sensitisation on the use and management of bags in cities

Temporal variation in body measurements in three Taurine cattle populations of Burkina Faso supports introgression of Zebu genes into West African Taurine cattle

A total of 769 adult females belonging to 3 taurine and one zebu cattle populations sampled in 3 provinces of Burkina Faso were assessed for 19 body measurements during two different years (2014 and 2018). The aim of this research was to identify temporal morphological variation in cattle bred in the humid southern zones to obtain empirical evidence supporting a possible introgression of zebu cattle genes into Gourounsi and Lobi taurine cattle breeds. Zebu cattle samples were used as out-group for both 2014 and 2018 subsets. Least square means of body measurements allowed to classify Burkina Faso taurine cattle into three subgroups according to body size (Gourounsi–Sanguié –GourS-, Gourounsi-Nahouri –GourN- and Lobi from the tallest to the smallest respectively). Principal Component Analysis suggested that in 2014, taurine populations were structured. Dispersion map constructed using the two first factors informed that the GourS population was well separated from both the Lobi and the GourN, which, in turn, overlapped. However, in 2018 a strong signal of homogenization was identified, with GourN partially overlapping the other two populations. Linear Discriminant Analysis suggested that about 20% of both GourS and GourN individuals were reciprocally misclassified. Clues for such increase have been pointed out by MANOVA analysis. Although on 2014, Lobi cattle was clearly smaller than Gourounsi and both GourS and GourN populations showed clear differences on body traits, on 2018 it could be assessed an increase in size in Lobi cattle and a strong homogenization signal within Gourounsi cattle. Zebu cattle gene flow southwards in Burkina Faso is likely to have caused these changes, suggesting a fast erosion of taurine cattle genetic background.

Effects of lenten fasting on body composition and biochemical parameters

Background: The catholic lenten fasting is the period of 40 days of fasting that precedes Easter. It is one of religious fasting less documented in the scientific literature. Thus the aim of our study was to evaluate the evolution of anthropometric and body composition and biochemical profile during Catholic lenten fasting.Methods: We conducted a prospective study, which took place during the period between one week before at the end of lenten fasting. Eleven fasters (4 women and 7 men), aged between 18 and 59 years were included in present study. Anthropometric, body composition parameters and biochemical profile were evaluated one week before, at 15th day and at the end of Lenten fasting.Results: Weight, body mass index (BMI) and visceral fat decreased significantly at the end of Lenten fasting. Lipid profile changed significantly during this fasting period. Total cholesterol (TC), low density lipoprotein – cholesterol (LDL-C) and triglycerides decreased significantly with fasting. High density lipoprotein – cholesterol (HDL-C) was remained unchanged during this fasting period while TC/HDL ratio was significantly decreased at the end of Lent.Conclusions: Present study showed that the fasting of Lent seems to have beneficial effects on reducing cardiovascular risk factors. Further studies are required to better understand the physiological mechanisms involved for a therapeutic use

Déterminants socio-économiques et culturels de l’errance des malades mentaux en zone urbaine au Burkina Faso

Au Burkina Faso, il existe une amélioration de l’accès aux soins psychiatriques dans l’ensemble du pays. Cependant, il est courant d’observer dans les rues des grandes villes, des malades mentaux errants, cohabitant avec le reste de la population. Cet article, purement descriptif visait à cerner les déterminants socioéconomiques et culturels, pouvant expliquer l’abandon sans soins de ces patients dans la ville de Ouahigouya. À la lumière de nos résultats, trois principaux types de facteurs ont été notés et pourraient expliquer cette situation : la pauvreté économique, l’absence de dispositif public de prise en charge des malades mentaux errants et la tolérance culturelle à la présence des malades mentaux errants non violents

Aspects épidémiologiques, cliniques et facteurs pronostiques des accidents vasculaires cérébraux ischémiques chez le sujet âgé à Bobo-Dioulasso, Burkina Faso: Epidemiological, clinical and prognosis aspects of ischemic stroke in the elderly in Bobo-Dioulasso, Burkina Faso

Context and objective. Strokes risk increases with age. The most common one is ischemic stroke. Our objective was to identify epidemiological, clinical features and the factors linked to the prognosis for survival of older patients hospitalized for ischemic stroke in Sourô Sanou Teaching Hospital of Bobo-Dioulasso. Methods. This was an analytical historical study on older patients aged ≥ 65 years, hospitalized for ischemic stroke at Sourô Sanou Teaching Hospital of Bobo-Dioulasso during the period from January 1st, 2017 to December 31st, 2019. Results. A total of 153 patients has been involved in this study. The intrahospital ischemic stroke frequency was 68. 61 % of all strokes in elderly. The average age was 73.98 years. The sex ratio M/F was 1.25. Chronic high blood pressure (61.43 %), alcoholism (21.56%), diabetes (14.37 %), and history of stroke (13.72 %) were the most frequent cerebrovascular risk factors in past medical history. The motor deficit represented the main reason for consultation. Atheromatous pathology was the main etiology. The mean duration of hospitalization was 16.21 days. The intrahospital mortality was 16. 99 %. Median survival was 53 days. The predictive factors of mortality were the age (p= 0.017; HR= 2.81; IC 95 %: 1.21-6.54) and coma (p= 0.010; HR= 4.68; IC95 %: 2.05-43.94). Conclusion. Stroke in the elderly at Bobo-Dioulasso is responsible for a high death rate. Optimization of management for elderly patients could contribute to a significant reduction of stroke mortality. Contexte et objectif. Le risque d’accident vasculaire cérébral (AVC) augmente avec l’âge. Notre objectif était d’identifier les caractéristiques épidémiologiques, cliniques et les facteurs liés au pronostic vital des sujets âgés hospitalisés pour AVC ischémique (AVCI) au Centre Hospitalier Universitaire Sourô Sanou de Bobo-Dioulasso. Méthodes. Il s’est agi d’une étude rétrospective portant sur une période allant du 1er janvier 2017 au 31 décembre 2019 et concernant tous les patients âgés de 65 ans et plus hospitalisés pour AVCI. Résultats. Au total, 153 dossiers médicaux ont été colligés. L’âge moyen était de 73,9 ans. Le sex-ratio M/F était de 1,25. Les facteurs de risque cardiovasculaire étaient principalement l’hypertension artérielle chronique (61,4 %), l’alcoolisme (21,5 %), le diabète (14,3 %), et l’antécédent d’AVC (13,7 %). Le déficit moteur était le principal motif de consultation. La pathologie athéromateuse était la principale étiologie. La durée moyenne d’hospitalisation était de 16,2 jours. Le taux de mortalité intrahospitalière était de 16,9 %. La médiane de survie était de 53 jours. Les facteurs prédictifs de la mortalité étaient l’âge (p= 0,017; HR= 2,81; IC 95 %: 1,21-6,54) et le coma (p= 0,010; HR= 4,68; IC 95 %: 2,05-43,94). Conclusion. L’AVCI chez la personne âgée à Bobo-Dioulasso est marqué par une mortalité intrahospitalière élevée. L’optimisation de la prise en charge des patients âgés pourrait contribuer à la réduction significative de la mortalité des AVC

Implementation of community-based cattle breeding programs in Burkina Faso

Community-based breeding programs (CBBP), are being implemented in the South-West of Burkina Faso. CBBP are participatory programs that involve all local stakeholders in all steps, from designing and planning of the breeding program, all the way to the selection of the breeding stock. They aim to improve local cattle breeds. The breeding program has been implemented in three sites. Cattle types included in the program are the pure Lobi (Baoulé) cattle in one site and Lobi x Zebu crossbreds in the other two. The program pursues the main interest of farmers to have bigger animals which are tolerant to trypanosomosis. In the he first round of selection, young bulls, aged three to five years, were recorded twice, at an interval of 6 months. The project team grouped bulls into three groups (top, medium, inferior) based on an index combining current body weight and growth. Selection committees consisting of male and female cattle owners made their choice of best young bulls based on this information and their own criteria. The three best bulls selected by the committees were only partly from the top groups based on preliminary grouping of the project team. Decision was taken by the farmers which bulls to keep for breeding and which ones to castrate or sell out, to avoid undesired mating. Joint use of bulls and bull exchange are still being negotiated by farmers, as it is not a customary practice in the region. Farmers were open and appreciated the concept very much. They understood that CBBP are long term and committed their efforts and participation

COVID-19 epidemiological, sociological and anthropological investigation: study protocol for a multidisciplinary mixed methods research in Burkina Faso

International audienceBackground: The world has high hopes of vaccination against COVID-19 to protect the population, boost economies and return to normal life. Vaccination programmes are being rolled out in high income countries, but the pandemic continues to progress in many low-and middle-income countries (LMICs) despite implementation of strict hygiene measures. We aim to present a comprehensive research protocol that will generate epidemiological, sociological and anthropological data about the COVID-19 epidemic in Burkina Faso, a landlocked country in West Africa with scarce resources. Methods: We will perform a multidisciplinary research using mixed methods in the two main cities in Burkina Faso (Ouagadougou and Bobo-Dioulasso). Data will be collected in the general population and in COVID-19 patients, caregivers and health care professionals in reference care centers: (i) to determine cumulative incidence of SARS-CoV-2 infection in the Burkinabe population using blood samples collected from randomly selected households according to the WHO-recommended protocol; (ii) develop a score to predict severe complications of COVID-19 in persons infected with SARS-CoV-2 using retrospective and prospective data; (iii) perform semi-structured interviews and direct observation on site, to describe and analyze the healthcare pathways and experiences of patients with COVID-19 attending reference care centers, and to identify the perceptions, acceptability and application of preventive strategies among the population. Discussion: This study will generate comprehensive data that will contribute to improving COVID-19 response strategies in Burkina Faso. The lessons learned from the management of this epidemic may serve as examples to the country authorities to better design preventive strategies in the case of future epidemics or pandemics. The protocol was approved by the Ministry for Health (N° 2020-00952/MS/CAB/INSP/CM) and the Health Research Ethics Committee in Burkina Faso (N° 2020-8-140)
