The existing image in the Sahel Sudan Africa is often that of accelerated insecurity of plant and animal production conditions. Face with the growing hostility of nature, the people have for a long time adopted water and soil conservation strategies or migration. Thus, water development, especially the dam as an anthropic activity on the natural landscape, a notion linked to that of environmental and health risk seems to be a negotiable alternative, an answer to climatic vagaries. In Burkina Faso, the people want the construction of dams because, firstly, they provide water for man and animals, secondly, water provides food for man and animals. It is also used for dry season farming, irrigation, fishing and grazing. The satisfaction that the proximity of a dam gives is sufficiently felt by the people in all the regions, and today, small dams and hydro-agricultural developments which are often interrelated are more and more becoming part and parcel of the Burkinabe countryside.Under these conditions, the dams and farms are the new development poles aimed at solving the decreasing problem of food production per head which is the result of increasing population. However, these choices must not overshadow the numerous health risks associated with irrigation farming.Among the water-borne diseases; schistosomiasis and geohelminthis seem to be the most sensitive disease to changes in the relations between the human community and their aquatic environment, because one of their characteristic traits is their ability to adapt and benefit from the newly-created environment that resulted from the hydroagricultural development. There are several factors leading to their outbreak, their spread and the difficulty in controlling them among others: the framework of aquatic biotope, their juxtaposition in space, distribution and the development process of the number of the parasites, vectors and the intermediary hosts, movement of the human population with different lines of parasites and their state of immunity, the behaviour of man-man-water-parasite relations and the hygiene of the environment, the perception of the people about the disease, the therapeutic means, and consequently the pertinence of the IEC, the statue of women and children in the parasite transmission and treatment programme. It has been realised that hydro arming is one of the factors that enhance the proliferation of vectors of transmission and flux of parasite hosts. All the players, (land developers, the population and scientists) have been urged to use all the means at their disposal to alleviate or even stop the spread of the disease which is decreasing the expected agricultural returns.

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., Results: Eighty-two stroke survivors (41 females; mean ± SD: 54.94 ± 11.6 years old) participated in the study. Internal consistency of each domain of the MOSE-Benin and the overall questionnaire was high (Cronbach's α: 0.78 to 0.92). Test-retest reliability was excellent ( n  = 31; ICC: 0.977 to 0.998). Overall, the standard error of measurement (SEM) and the minimum detectable change (MDC) showed very low values (SEM = 0.85; MDC = 2.35). Convergent validity demonstrated moderate correlations for the three domains in separate comparison respectively with the ACTIVLIM-Stroke questionnaire, the Participation Measurement Scale, and the communication domain of the Stroke Impact Scale (r or ρ: 0.42 to 0.54; p  < 0.0001)., Conclusion: MOSE-Benin has good evidence regarding psychometric properties (i.e., content validity, convergent validity, internal consistency, and test-retest reliability) that can support its use for the assessment of perceived environmental barriers after stroke in a French-speaking Sub-Saharan African country, such as Benin.

Cover crops (CCs) are increasingly used in viticulture because they benefit the soil and the environment in many ways. This study investigated the extent to which the incorporation of CC residues altered organic matter (OM) and Cu dynamics in a Cu-contaminated vineyard topsoil. A 92-day incubation period was used to monitor changes over time in carbon mineralization, carbon hydrolytic enzyme activity, concentration and optical properties of dissolved organic matter (DOM), and Cu solubility after the addition (or not) of two CC residues, oat or faba bean. The results revealed that adding CCs transitorily increased the concentration of DOM in soil solution, as well as the activity of C hydrolytic enzymes and C mineralization rates. DOM content was approximately two orders of magnitude higher in CC-amended soils than in the control soil on day 0, after which it gradually decreased to reach concentrations similar to those measured in the control soil on day 92. Analyses of DOM optical properties showed that its molecular weight and degree of humification increased over time with a decrease in its concentration. The close relationship between DOM and Cu concentrations in the soil solution suggests that degradation of CCs releases soluble forms of C capable of complexing and solubilizing Cu, and hence that incorporating CC residues can transitorily increase the solubility of Cu in vineyard topsoils. Despite their different C:N ratios, oat and faba bean had almost the same effect on Cu dynamics, implying that C inputs played a prominent role in explaining the interactions between OM and Cu within the timeframe of our experiment. In conclusion, this study enabled recommendations on how to mitigate the risk of Cu ecotoxicity associated with incorporating CCs in Cu-contaminated vineyard soils., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Telerehabilitation (TR) is a promising method for facilitating the delivery and access to post-stroke rehabilitation services., Objective: The aim of this study was to explore the acceptability of TR and factors influencing its adoption by individuals with stroke and caregivers., Methods: A qualitative descriptive approach was used. Six individuals with stroke and three caregivers participated in individual online interviews. An abductive thematic analysis was employed to analyze the qualitative data, using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT-2) model., Results: Participants reported positive experiences with TR, resulting in improvements in functional abilities, such as manual dexterity, balance, and positive interactions with therapists. They found the technology easy to learn and use, facilitating engagement in TR. Participants' prior experiences with technology, along with support from caregivers and therapists, facilitated acceptance and the use of TR. The COVID-19 pandemic also motivated participants to accept TR. However, technical issues, unstable internet connections, and lack of feedback were barriers to the use of TR., Conclusion: Despite existing obstacles, TR can be used to provide rehabilitation services for individuals with stroke. Addressing these barriers is necessary to promote the widespread and effective use of TR in the context of stroke recovery.

Background: In rural African settings, most of the children under the coverage of Seasonal Malaria Chemoprevention (SMC) are also undernourished at the time of SMC delivery, justifying the need for packaging malarial and nutritional interventions. This study aimed at assessing the impact of SMC by coupling the intervention with nutrients supplementation for preventing malaria in children less than 5 years old in Burkina Faso., Methods: A randomized trial was carried out between July 2020 and June 2021 in the health district of Nanoro, Burkina Faso. Children (n = 1059) under SMC coverage were randomly assigned to one of the three study arms SMC + Vitamin A (SMC-A, n = 353) or SMC + Vitamin A + Zinc (SMC-AZc, n = 353) or SMC + Vitamin A + PlumpyDoz(tm) (SMC-APd, n = 353)-a medium quantity-lipid-based nutrient supplement (MQ-LNS). Children were followed up for one year that included an active follow-up period of 6 months with scheduled monthly home visits followed by 6 months passive follow-up. At each visit, capillary blood sample was collected for malaria diagnosis by rapid diagnosis test (RDT)., Results: Adding nutritional supplements to SMC had an effect on the incidence of malaria. A reduction of 23% (adjusted IRR = 0.77 (95%CI 0.61-0.97) in the odds of having uncomplicated malaria in SMC-APd arm but not with SMC-AZc arm adjusted IRR = 0.82 (95%CI 0.65-1.04) compare to control arm was observed. A reduction of 52%, adjusted IRR = 0.48 (95%CI 0.23-0.98) in the odds of having severe malaria was observed in SMC-APd arm compared to control arm. Besides the effect on malaria, this combined strategy had an effect on all-cause morbidity. More specifically, a reduction of morbidity odds of 24%, adjusted IRR = 0.76 (95%CI 0.60-0.94) in SMC-APd arm compared to control arm was observed. Unlike clinical episodes, no effect of nutrient supplementation on cross sectional asymptomatic infections was observed., Conclusion: Adding nutritional supplements to SMC significantly increases the impact of this intervention for preventing children from malaria and other childhood infections., Trial Registration: NCT04238845., (© 2023.

Purpose: To evaluate the association between depression/anxiety and activity limitations and health-related quality of life (HRQoL) in chronic stroke survivors in Benin., Materials and Methods: One hundred and seventy-six chronic stroke survivors (113 males; mean age (±SD): 56.5 (±10.5) years old) were included. We used the Barthel index (BI) to assess activity limitations. Participants were screened for depression and anxiety symptoms using Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale (HARS). Euroqol-5 Dimensions-3 Levels (EQ-5D-3L) including a Visual Analog Scale (EQ-VAS) was used to assess HRQoL. Multivariate linear regressions were performed to determine the impact of psychological disorders on activity limitations and HRQoL., Results: Depression ( β =-0.54; p  < 0.0001) and anxiety ( β =-0.35; p  < 0.0001) were negatively associated with activity limitations ( R 2 =0.60). Similar patterns of association were observed with HRQoL ( β ≤-0.28; p  < 0.0001; R 2 ≥0.40). Inversely, occupational status showed positive association with EQ-5D-3L summary index scores ( β  = 0.21; p  = 0.015)., Conclusions: Depression and anxiety had a negative impact on activity limitations and HRQoL in Beninese chronic stroke survivors. This call for action to integrate psychological interventions as part of rehabilitation programs in low and middle-income countries.Implications for rehabilitationPost-stroke depression and anxiety are quite common among stroke survivors in sub-Saharan Africa.Post-stroke depression and anxiety negatively impact activities and health-related quality of life in chronic stroke survivors in sub-Saharan Africa.Managing these post-stroke psychological disorders is necessary to promote the functional recovery and social reintegration of stroke survivors in their communities.

Malaria is a permanent threat to health in western Burkina Faso. Research has shown that geographical variables contribute to the spatial distribution in its transmission. The objective of this study is to assess the relationship between malaria prevalence and potential explanatory geographical variables in the Houet province in Burkina Faso. Statistics on malaria prevalence registered by health centres in the Houet province in 2017 and potential geographical variables identified through a literature review were collected. An Ordinary Least Squares (OLS) regression was used to identify key geographical variables and to measure their association with malaria while the Getis Ord Gi* index was used to locate malaria hotspots. The results showed that average annual temperature, vegetation density, percentage of clay in the soil, total annual rainfall and distance to the nearest waterbody are the main variables associated with malaria prevalence. These variables account for two-thirds of the spatial variability of malaria prevalence observed in Houet province. The intensity and direction of the relationship between malaria prevalence and geographical factors vary according to the variable. Hence, only vegetation density is positively correlated with malaria prevalence. Average temperature, for soil clay content, annual rainfall and for distance to the nearest water body are negatively correlated with the disease prevalence. These results show that even in an endemic area, malaria prevalence has significant spatial variation. The results could contribute to the choice of intervention sites, as this choice is crucial for reducing the malaria burden., Supplementary Information: The online version contains supplementary material available at 10.1007/s10708-022-10692-7., Competing Interests: Conflict of interestThe authors declare that they have no competing interests., (© The Author(s) 2022.)

This study characterizes market gardening in Houet province in order to determine the various categories of market gardening farms based on specific socioeconomic variables, as well as to analyze the main factors influencing their economic performance. Using principal component analysis (PCA) and hierarchical ascending classification, the main factors influencing the economic situation of the market garden farms in Houet were analyzed through the interrelationships between the variables considered. Findings revealed four clusters of vegetable farms with different socioeconomic features depending on the farming environment (urban, peri-urban and rural). In the same vein, the results showed that market gardeners in urban areas have the best economic performance. With the regard to the durability of the production, results showed that the majority of market gardeners (95%) have a conventional production method and often use in an uncontrolled way chemical pesticides, as well as mineral fertilizers that some combine with organic amendments., Competing Interests: The authors declare no competing interests., (© 2022 The Author(s).)

Accumulation of copper (Cu) in soils due to the application of fungicides may be toxic for organisms and hence affect winegrowing sustainability. Soil parameters such as pH and dissolved organic matter (DOM) are known to affect the availability of Cu. In this study, we investigated the contribution of chromophoric and fluorescent DOM properties to the prediction of Cu availability in 18 organic vineyard soils in the Bordeaux winegrowing area (France). The DOM parameters, assessed through absorbance and fluorescence analyses, and proxies for Cu availability (total soluble Cu and free ionic Cu 2+ ) were measured in 0.01 M KCl extracts. Total soluble Cu (Cu KCl ) varied 23-fold while free ionic Cu 2+ varied by a factor of 4600 among the soils. DOC concentrations were similar among the soils, but the samples differed in the quality of DOM as assessed by optical spectroscopy. Multilinear regression models with and without DOM quality parameters were investigated to predict Cu availability. The best model for Cu KCl successfully explained 83% of variance and included pH, Cu T , and two DOM fluorescence quality indices, the FI fluorescence index, which distinguishes between microbial and higher plant origins, and the HIX humification index. For the prediction of Cu 2+ , pH alone explained 88% of variance and adding DOM parameters did not improve modelling. The two Cu availability proxies were related to pH. This study confirms the prominent role of pH in Cu availability and underlines the importance of DOM quality to better predict Cu solubility., (© 2021.

Background: Plasmodium falciparum malaria remains a major public health concern in sub-Sahara Africa. Seasonal malaria chemoprevention (SMC) with amodiaquine + sulfadoxine-pyrimethamine is one of the most important preventive interventions. Despite its implementation, the burden of malaria is still very high in children under five years old in Burkina Faso, suggesting that the expected impact of this promising strategy might not be attained. Development of innovative strategies to improve the efficacy of these existing malaria control measures is essential. In such context, we postulate that screening and treatment of malaria in household members of children receiving SMC could greatly improve the impact of SMC intervention and reduce malaria transmission in endemic settings., Methods: This randomized superiority trial will be carried out in the Nanoro health district, Burkina Faso. The unit of randomisation will be the household and all eligible children from a household will be allocated to the same study group. Households with 3-59 months old children will be assigned to either (i) control group (SMC alone) or (ii) intervention (SMC+ screening of household members with standard Histidin Rich Protein Rapid Diagnostic Test (HRP2-RDT) and treatment if positive). The sample size will be 526 isolated households per arm, i.e., around 1052 children under SMC coverage and an expected 1315 household members. Included children will be followed-up for 24 months to fully cover two consecutive malaria transmission seasons and two SMC cycles. Children will be actively followed-up during the malaria transmission seasons while in the dry seasons the follow-up will be passive., Conclusion: The study will respond to a major public health concern by providing evidence of the efficacy of an innovative strategy to boost the impact of SMC intervention., (© 2022.

Background: Malaria and malnutrition represent major public health concerns worldwide especially in Sub-Sahara Africa. Despite implementation of seasonal malaria chemoprophylaxis (SMC), an intervention aimed at reducing malaria incidence among children aged 3-59 months, the burden of malaria and associated mortality among children below age 5 years remains high in Burkina Faso. Malnutrition, in particular micronutrient deficiency, appears to be one of the potential factors that can negatively affect the effectiveness of SMC. Treating micronutrient deficiencies is known to reduce the incidence of malaria in highly prevalent malaria zone such as rural settings. Therefore, we hypothesized that a combined strategy of SMC together with a daily oral nutrients supplement will enhance the immune response and decrease the incidence of malaria and malnutrition among children under SMC coverage., Methods: Children (6-59 months) under SMC coverage receiving vitamin A supplementation will be randomly assigned to one of the three study arms (a) SMC + vitamin A alone, (b) SMC + vitamin A + zinc, or (c) SMC + vitamin A + Plumpy'Doz™ using 1:1:1 allocation ratio. After each SMC monthly distribution, children will be visited at home to confirm drug administration and followed-up for 1 year. Anthropometric indicators will be recorded at each visit and blood samples will be collected for microscopy slides, haemoglobin measurement, and spotted onto filter paper for further PCR analyses. The primary outcome measure is the incidence of malaria in each arm. Secondary outcome measures will include mid-upper arm circumference and weight gain from baseline measurements, coverage and compliance to SMC, occurrence of adverse events (AEs), and prevalence of molecular markers of antimalarial resistance comprising Pfcrt, Pfmdr1, Pfdhfr, and Pfdhps., Discussion: This study will demonstrate an integrated strategy of malaria and malnutrition programmes in order to mutualize resources for best impact. By relying on existing strategies, the policy implementation of this joint intervention will be scalable at country and regional levels., Trial Registration: ClinicalTrials.gov NCT04238845 .

Introduction: Despite the implementation of various nutritional interventions, access to healthy food in sufficient quantity for the population remain challenging in Burkina Faso. The objective of this study was to assess the nutritional status of infants aged 6-23 months and to identify factors associated with malnutrition., Patients and Methods: From 1 st May to 31th July 2016, we conducted a cross-sectional study at Yalgado Ouedraogo University Hospital paediatric department. Infants aged 6 to 23 months admitted to the paediatric emergency department were enrolled. Factors associated with malnutrition were identified using multivariate logistic regression., Results: A total of 295 infants were included, at an average age of 13 months (standard deviation: 5.1 months). The prevalence of wasting was 15%, 13% was stuntingand 7% was underweight. The majority of mothers (69%) were unaware of exclusive breastfeeding and only 22% knew the importance of colostrum. In multivariate analysis age ≥ 12 months increased the odds of wasting (adjusted odds ratio [aOR]: 2.3, 95% confidence interval: 1.1-4.7), while knowledge of exclusive breastfeeding reduced the risk of wasting (aOR: 0.4, 95% CI 0.2-0.9). In addition, age ≥12 months (aOR: 0.08, 95% CI: 0.03-0.22), female gender (aOR: 0.31, 95% CI: 0.12-0.77) and absence of dietary restrictions (aOR: 0.13, 95% CI: 0.05-0.3) significantly reduced the odds of stunting., Conclusion: The prevalence of malnutrition remains high in paediatric department in Burkina Faso. Routine screening and adequate management of malnutrition, coupled with the promotion of optimal nutritional practices in childhood, is needed to improve child healthcare., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

This is a case-control study conducted to examine the risk factors for multidrug resistance (MDR) among patients with pulmonary tuberculosis (TB) in four centers in Burkina Faso, West Africa: Ouagadougou, Bobo-Dioulasso, Gorom-Gorom, and Dori. Fifty-six MDR-TB cases and 304 controls were enrolled of which 40 MDR-TB cases and 222 controls were from Ouagadougou. The majority of cases were male, with 39 among MDR-TB cases and 205 in controls. The MDR-TB cases were aged from 14 to 75 years versus 11 to 75 years in the controls. The total risk assessment battery score was 11. Living outside of Burkina Faso (adjusted odds ratio [OR] = 0.017; 95% confidence interval [95% CI]: 0.001-0.325), known TB contact (OR = 0.045; 95% CI: 0.004-0.543), and patients with previous history of TB treatment (OR = 0.004; 95% CI: 0.000-0.0.052) were significantly associated with MDR-TB. TB contact and mainly previous treatment were the strongest determinants of MDR-TB. Also, living outside Burkina was a risk factor.
