Resumen

Au Mali, les pertes en reproduction constituent des contraintes majeures à l’amélioration de la productivité de l’élevage des petits ruminants. Parmi les causes de ces pertes qui demeurent mal connues figurent, entre autres, l’infertilité, les avortements, l’orchite et la chétivité. L’objet de la présente étude a été d’évaluer la prévalence sérologique de la fièvre Q dans les élevages de petits ruminants où des cas de pertes en reproduction ont été observés, ainsi que la valeur financière des pertes liées aux avortements enregistrés. L’étude a été conduite entre 2006 et 2009 dans les zones agropastorales des localités de Bougouni (région de Sikasso), Nioro (région de Kayes), Kéniébougouwéré (région de Ségou) et Koro (région de Mopti). Sur les 718 sérums analysés par la méthode Elisa indirecte, 155 (21,5 ± 3 p. 100) se sont révélés positifs aux anticorps de Coxiella burnetii. Cette prévalence a varié en fonction des sites et du rang de portée. La prévalence la plus élevée a été observée à Kéniébougouwéré (35 ± 6 p. 100), suivi de Nioro (28,5 ± 7,5 p. 100), puis de Bougouni (10,8 ± 4,6 p. 100), et la plus faible à Koro (5,8 ± 3,7 p. 100). Des études complémentaires intégrant le diagnostic moléculaire (technique PCR) pourraient aider à élucider le rôle étiologique de cette pathologie dans les cas de pertes en reproduction couramment enregistrés chez les petits ruminants au Mali. L’analyse technico-économique a permis d’évaluer la valeur financière des pertes.

Resumen

The 2022 field season (January 23 – February 23) turned out to be very productive: we managed to clarify the history of Dogon migrations from the Mande Country to the Bandiagara Highlands. We received quite complete information on the prophet Abirɛ, who predicted the return of Dogon to their historical homeland and completely new information about Bozo and Bambara puppets. Finally, we acquired many interesting artifacts for the State Museum of Oriental Arts. Due to the inability to arrive to the Dogon Country, it was decided to focus on the area of the city of Bougouni (Sikasso region) in southern Mali and on the Mande Country (regions of Koulikoro and Kayes, from the city of Kangaba in the west to Bamako in the east). Two magnificent, beautifully attributed works of traditional Bambara art were acquired in Bougouni for the collection of the State Museum of Oriental Arts: “Monkey” (Warabilen) and “Wild buffalo” (Sigi; Sigifin) masks. During the expedition, new and very significant data were obtained on the migrations of the Dogon from the Mande Country to the Bandiagara Highlands. A lot of information has now been accumulated regarding how the Dogon came to their new homeland. They were published, including in Russian. But the Manding oral traditions about the exodus of Dogon are still little known. We have partially succeeded in making up for this shortcoming. Oral historical traditions about the exodus of the Dogon from the Mande Country are changeable, internally contradictory and extremely unstable narratives with confused chronology, filled with omissions and vague allusions. However, some conclusions can still be drawn: there is almost no doubt that the root cause of the Dogon leaving for the lifeless rocks of Bandiagara was some kind of difficult and bloody conflict, accompanied by numerous victims. It is also clear that there were several waves of resettlement, and the last Dogon left for the highlands in the middle of the second half of the 19th century. It was also possible to find out that the Bambara and Bozo puppets are not at all a secularized popular theater. The puppet society is associated with the Koré secret society, and is perhaps one of the most powerful Bambara societies, which in this case refers to three ethnic groups: the Bambara proper, the Bozo (Dogon partners in a marriage-prohibitive joking relations) and the Marka (Soninké). Ceremonies involving puppets are completely sacred (only members of the Society take part in them), semi-sacred (only men take part in them), and, finally, publicly available — everyone, including women and children, takes part in them.

Resumen

Au Mali, l'élevage des espèces à cycle court en général et celui des petits ruminants en particulier constitue une source précieuse de revenus et de protéines pour les populations. Cependant, au nombre des contraintes à l'amélioration de la productivité de cet élevage, figurent les pertes en reproduction, dont les causes demeurent mal connues. Les données relatives au rôle de certaines infections microbiennes comme la brucellose à Brucella ovis, chlamydiose et la toxoplasmose sont quasi inexistantes. L'objet de la présente étude a été d'évaluer la prévalence sérologique de ces pathologies, susceptibles de causer des pertes en reproduction chez ces espèces animales. Elle a couvert quatre sites dont Kéniébougou (Cercle de Ségou), Nioro (Cercle de Nioro), Bougouni (Cercle de Bougouni) et Briga (Cercle de Koro), choisis en collaboration étroite avec les services techniques d'encadrement et éleveurs de petits ruminants desdites localités. Au total 872 sérums (368 ovins et 504 caprins) issus des sujets présentant des signes de perte en reproduction ont été testés par la méthode Elisa indirecte. Parmi ceux-ci, 81 (9,28 %) se sont révélés positifs (1,26 % en brucellose à Brucella ovis, 3,55 % en chlamydiose à Chlamydia abortus et 4,47 % en toxoplasmose à Toxoplasma gondii). Les anticorps mis en évidence sont considérés comme d'origine infectieuse, les animaux n'ayant jamais été vaccinés contre les maladies investiguées, ce qui confirme la circulation des agents étiologiques des trois infections abortives parmi les populations de petits ruminants au Mali.

Resumen

In the south of the Sahara, the cultivation of land leads to a rapid decrease in nutrients and the appearance of deficiencies in nitrogen, phosphorus, magnesium, calcium, and other elements. The major constraint of production in this area on agricultural soils is the low level of soil fertility. The objective of this study was to evaluate the effects of different amendment formulas on cotton and maize yields as well as their financial returns in order to propose a recommendable formula. To achieve this objective, the experimental set-up used was a dispersed series of five treatments of 3125 m² per school field in 6 villages in the circles of Sikasso, Koutiala and Bougouni, with each village constituting a replication. Four formulations were tested in addition to the farmer's practice, namely (i) agricultural lime (300 Kg/ha) combined with 300 Kg/ha of TNP, (ii) agricultural lime (500 Kg/ha) combined with 500 Kg/ha of TNP, (iii) agricultural lime at a dose of 300 Kg/ha and agricultural lime at a dose of 500 Kg/ha. Analysis of the results shows that the effect of the amendments varies according to the site (soil acidity level). The best marginal rates of return were recorded in Sikasso with T5 (665%), which is well above the recodable minimum (50-100%), followed by T2 (195%) at the same site. The T4 treatment remains the optimal treatment in Koutiala because it has the lowest recommendation rate (52%) compared to the farmer's practice. We also noted that all treatments in Bougouni were dominated by the farmer's practice. With respect to the evaluation of after-effects, treatments T4 and T3 remain the satisfactory treatments in Bougouni, while in Sikasso it is T4 and T2 provided the best after-effects.

Resumen

Introduction : La schistosomiase constitue un enjeu de santé publique d'envergure mondiale, affectant le plus souvent les enfants, elle semble être liée au développement et l'augmentation des réseaux d'irrigation. L'efficacité des traitements de masse (TDM) ciblant les schistosomiases reste compromise par la non compliance au Mali. L'objectif était d'étudier les facteurs associés à la non compliance au TDM dans trois districts sanitaire : Bougouni, Bankass, et Tominian. Matériel et méthodes : Il s'agissait d'une étude transversale avec analyse secondaire des données de 2277 participants âgés de 5 - 14 ans et/ou leurs parents issues de l'enquête réalisée de juin à décembre 2017 dans les districts sanitaires de Bankass, Bougouni et Tominian. La non compliance a été évaluée en utilisant une analyse uni et multi variée (régression logistique) avec le logiciel STATA version13. Résultats : La religion (p=0,0001), la profession du père (p=0,006), la peur des effets secondaires (p=0,001) et la présence d'hématurie terminale (p=0,001) ont été trouvées statistiquement associées à la non compliance. En terme de contribution au model, la religion explique plus la non compliance, suivie de la peur des effets secondaires avec respectivement 43,79%, 18,79%, le sexe contribue moins avec seulement 1,09%. Conclusion : La religion, la profession du père, la peur des effets secondaires et la présence d'hématurie terminale étaient des facteurs statistiquement associés à la non compliance. Une intervention basée sur l'éducation sanitaire serait nécessaire afin de minimiser le taux de non compliance au TDM ciblant les schistosomiases.

Resumen

Understanding the perception of sack gardening technology is important in order to better support the adoption of sack gardening in households, given the nutritional role vegetables play. This notwithstanding, research has not yet been carried out to understand the stakeholders’ perception of sack gardening technology in the zones of Bougouni and Koutiala, where sack gardening technology was introduced under the Africa Research in Sustainable Intensification for the Next Generation (Africa-RISING) project. This study assessed the perception of farm households on sack gardening technology and specifically to understand to what extent this innovation responds to household needs. Q-methodology was used to identify rural household’s viewpoints and principal component analysis (PCA) was performed to compare stakeholders’ opinion typologies to discourses retained by Q-method results. Focus group discussions were used to identify the statements used for the q-set in the individual surveys. Our findings showed three factors or discourses which reflected the stakeholders’ viewpoints. A nutritional role, the role of making vegetables available for household consumption and the role of environment protection, specifically soil protection, were indicated in the stakeholders’ opinions. The understanding of the different discourses retained provides insights that can be used to design public and private interventions to support the usage of the technology in households or the adoption of this technology.

Resumen

Measles is a highly contagious viral disease caused by the morbillivirus of which humans are the only reservoir. Our descriptive study aims at analyzing retrospective measles surveillance data from 2022. Of the 2037 suspected measles case samples received at the laboratory, 784 (38%) were confirmed. The age group of 1-4 years is the most affected with an attack rate of 25.43 per 100,000 inhabitants. Children under 5 represent 47.71% of cases. The median age is 4 years and the average age 6.14 years (0 months-54 years). The male sex represents 51% of cases with a sex ratio of 1.06 and an attack rate of 9.72 per 100,000 inhabitants. Most confirmed measles cases (71.77%) were recorded during the dry season. The districts of Koutiala (140 cases: 17.85%), Sikasso (127 cases: 16.19%), Ségou (109 cases: 13.09%) and Bougouni (98 cases: 12.5%) record the most case. The average time for feedback from the laboratory was 3.95 days. Moreover, among the 1253 sample cases negative for measles, 8.22% were positive for rubella. The median age of patients was 6 years. Children under five are the most affected. Most of these cases are in unvaccinated people. The establishment of an enhanced vaccination program at country level considering the most affected groups could reduce the resurgence of measles epidemics. Keywords: Epidemic, Measles, Mali, Notifiable disease (MADO), Spatiotemporal.

Resumen

<p class="1Body">Decentralized governance of natural resources is considered one of the key strategies for promoting sustainable management of natural resources at local level. Effective decentralized natural resource management requires strong local natural resource institutions. Therefore, strengthening local institutions governing the management of natural resources is one of the core principles of decentralization reforms in Francophone West Africa countries. This study assessed the existing local institutions (rules, norms and or local conventions) governing the management of natural resources and forms of community participation in the development of these natural resource institutions. Our findings showed significant variation within the study sites regarding the level of knowledge of existing local rules and norms governing the management of natural resources by the respondents. Results showed that the level of knowledge of local conventions was significantly (P < 0.05) higher in the district of Bougouni than in the district of Koutiala (a score of 3.16 compared to 1.70 on a scale of 0 to 4).This study shows also that participation was dominated by a small group of individuals, often community leaders and elites. The results suggest that women are marginalized. Presently, the big challenge that faces the institutions governing natural resource use in the study area is the system of representativeness in the community in the development of local rules and norms as community leaders and household heads often dominate, which does not encourage active participation of community members. Therefore, for effective implementation of local natural resource institutions, the interest of key natural resource users should be taken into account. It is also important to promote rules and norms that attempt to protect or strengthen women’s access to natural resources in the community.</p>

Resumen

Cotton is a strategically important crop for Mali. Mainly used for export, it represents 50–60 % of the value of the country's exports. Genotype by environment interaction study was carried out to identify the most stable cotton genotype(s) and the most desirable for seed cotton yield and lint yield in 35 villages across six different environments(High Valley of the Niger, New Cotton Growing Zone, North Sudan-Sahel, Old Basin, Southern Extension Zone and Zone Sikasso-Bougouni) in a dispersed block design. Where each village represented a block, giving a total of 35 blocks or replications. A combined analysis of variance showed that yields of seed cotton and fiber were significantly affected by environments (p<0.05), but did not reveal any significant difference between genotypes or genotype-environment interactions. The result of GGE biplot analysis method showed that the polygonal view identified three mega-environments (ME1, ME2 and ME3) with three winning genotypes: BRS 293, NTA B149 and NTA L66, respectively, for seed cotton yield. For fiber yield, the winning genotypes were CG1, NTA L65 and BRS 293, respectively. Given that all the varieties tested have a mean fiber yield within the recommended norms, the two promising varieties NTA B149 and NTA L66 with good seed cotton yields and the standard check BRS 293 can be recommended for extension in the environments to which they have been assigned.

Resumen

Bacterial canker (or black spot) of mango caused by Xanthomonas citri pv. mangiferaeindicae is an important disease in tropical and subtropical areas (1). X. citri pv. mangiferaeindicae can cause severe infection in a wide range of mango cultivars and induces raised, angular, black leaf lesions, sometimes with a chlorotic halo. Severe leaf infection may result in abscission. Fruit symptoms appear as small, water-soaked spots on the lenticels that later become star shaped, erumpent, and exude an infectious gum. Often, a “tear stain” infection pattern is observed on the fruit. Severe fruit infections cause premature drop. Twig cankers are potential sources of inoculum and weaken branch resistance to winds. Yield loss up to 85% has been reported at grove scale for susceptible cultivars (1). Suspected leaf lesions of bacterial canker were collected in July 2010 from mango trees in four, six, and three localities of the Koulikoro, Sikasso, and Bougouni provinces of Mali, respectively (i.e., the major mango-growing areas in this country). Nonpigmented Xanthomonas-like colonies were isolated on KC semiselective medium (3). Twenty-two strains from Mali were identified as X. citri pv. mangiferaeindicae based on IS1595-ligation-mediated PCR (4) and they produced fingerprints fully identical to that of strains isolated from Ghana and Burkina Faso. Five Malian strains (LH409, LH410, LH414, LH415-3, and LH418) were compared by multilocus sequence analysis (MLSA) to the type strain of X. citri and the pathotype strain of several X. citri pathovars, including pvs. anacardii and mangiferaeindicae. This assay targeted the atpD, dnaK, efp, and gyrB genes, as described previously (2). Nucleotide sequences were 100% identical to those of the pathotype strain of X. citri pv. mangiferaeindicae whatever the gene assayed, but differed from any other assayed X. citri pathovar. Leaves of mango cv. Maison Rouge from the youngest vegetative flush were infiltrated (10 inoculation sites per leaf for three replicate leaves on different plants per bacterial strain) with the same five strains from Mali. Bacterial suspensions (~1 × 105 CFU/ml) were prepared in 10 mM Tris buffer (pH 7.2) from 16-h-old cultures on YPGA (7 g of yeast, 7 g of peptone, 7 g of glucose, and 18 g of agar/liter, pH 7.2). The negative control treatment consisted of three leaves infiltrated with sterile Tris buffer (10 sites per leaf). Plants were incubated in a growth chamber at 30 ± 1°C by day and 26 ± 1°C by night (12-h/12-h day/night cycle) at 80 ± 5% relative humidity. All leaves inoculated with the Malian strains showed typical symptoms of bacterial canker a week after inoculation. No lesions were recorded from the negative controls. One month after inoculation, mean X. citri pv. mangiferaeindicae population sizes ranging from 5 × 106 to 1 × 107 CFU/lesion were recovered from leaf lesions, typical of a compatible interaction (1). To our knowledge, this is the first report of the disease in Mali. Investigations from local growers suggest that the disease may have been present for some years in Mali but likely less than a decade. A high disease incidence and severity were observed, suggesting the suitability of environmental conditions in this region for the development of mango bacterial canker. References: (1) N.

Resumen

ABSTRACT. Throughout a phase IIIb/IV efficacy study of repeated treatment with four artemisinin-based combination therapies, significant heterogeneity was found in the number of clinical episodes experienced by individuals during the 2-year follow-up. Several factors, including host, parasite, and environmental factors, may contribute to the differential malaria incidence. We aimed to identify risk factors of malaria incidence in the context of a longitudinal study of the efficacy of different artemisinin-based combination therapy regimens in Bougoula-Hameau, a high-transmission setting in Mali. Risk factors including age, residence, and treatment regimen were compared among individuals experiencing eight or more clinical episodes of malaria (“high-incidence group”) and individuals experiencing up to three clinical episodes (“low-incidence group”). Consistent with the known association between age and malaria risk in high-transmission settings, individuals in the high incidence group were significantly younger than individuals in the low-risk group (mean age, 7.0 years versus 10.6 years, respectively; t-test, P < 0.0001). Compared with individuals receiving artemether-lumefantrine, those receiving artesunate-amodiaquine had greater odds of being in the high-incidence group (odds ratio [OR], 2.24; 95% CI, 1.03 – 4.83, P = 0.041), while individuals receiving dihydroartemisinin-piperaquine had a lower odds of being in high incidence group (OR: 0.30, 95% CI, 0.11–0.85; P = 0.024). Individuals residing in the forested areas of Sokourani and Karamogobougou had significantly greater odds of being in the high-incidence group compared with individuals residing in the semi-urban area of Bougoula-Hameau 1 (Karamogobougou: OR, 3.68; 95% CI, 1.46–9.31; P = 0.0059; Sokourani: OR, 11.46; 95% CI, 4.49–29.2; P < 0.0001). This study highlights the importance of fine-mapping malaria risks even at sub-district levels for targeted and customized interventions.

Resumen

_ A gold strike was announced in late October. But in this case the gold was naturally occurring hydrogen in a former coal basin. Known as “white” or “gold” hydrogen, the reported discovery of naturally formed underground hydrogen was made in northeastern France’s Lorraine coal basin, a region between France and Germany. The last coal mine was shut down 20 years ago. Researchers at the French National Centre of Scientific Research (CNRS) were testing a probe designed to analyze gases dissolved in the water of deep underground rock formations, looking for methane, when they detected hydrogen concentrations at depths of 1100 m (14%) and 1250 m (20%). Their calculations estimated the deposits’ potential as between 6 and 250 million metric tons of hydrogen. This wasn’t their first discovery of underground hydrogen in the area. Philippe de Donato and Jacques Pironon made a similar finding “by chance” as part of the Regalor research project in collaboration with Française de l’Energie (FDE), an independent multienergy company, the University of Lorraine, and CNRS. FDE announced the discovery in a press release in May, saying the measurements of hydrogen were made in its previously drilled Folschviller wellsite in the carboniferous aquifer of the Lorraine basin. Launched in 2018, the project’s aim was to confirm an assessment carried out in 2012 by France’s IFPEN petroleum and new energies institute. After analyzing a sample of the soil under the basin, the institute concluded that it contained 370 billion m3 of methane, which represents 8 years of gas consumption in France. De Donato and Pironon said, “The work carried out within the framework of the Regalor project has made it possible to demonstrate that the fluids within the carboniferous formations of the Lorraine mining basin are very significantly enriched in hydrogen, with a measured concentration of 15% at 1093 m depth and estimated at 98% at 3000 m depth.” FDE said in May that it applied for an exclusive mining exploration permit for the exploration of natural hydrogen in the basin. The permit covers an area of 2254 km² in the Grand Est region. The company said a site for a pilot will be identified based on the results obtained and then built to initiate local production and recovery of natural hydrogen in the Grand Est Region. In its October investor update, FDE said measurements will be performed in three of its existing wells by the end of the year to determine the extent of the hydrogen deposit. Reservoirs have also been discovered in the US, Canada, Finland, the Philippines, Australia, Brazil, Oman, Turkey, and Mali. In Mali, the Bourakebougou water well, Bougou-1, was drilled in 1987 in the Taoudeni Basin (https://doi.org/10.1016/j.ijhydene.2018.08.193), a large sedimentary system present mainly in Algeria, Mauritania, and Mali. The well was cemented after a gas explosion occurred during drilling operations at a measured depth of 112 m. Unplugged in 2011 for use as a pilot well for local hydrogen production, gas was reported comprising 98% hydrogen, 1% nitrogen, and 1% methane. Hydrogen was then produced as an energy resource to supply local electricity through a company named Petroma, renamed Hydroma. From 2017 to 2019, the company drilled 24 wells. Among the new breed of gold prospectors are several startup companies including Natural Hydrogen Energy, Koloma, Helios Aragon, Gold Hydrogen, HyTerra, and H2Au. Helios Aragon owns exploration permits in northern Spain’s Aragon region and will begin drilling the Monzon-2 appraisal well in 2024 at a cost of $12 million. Estimates for the well are 1.1 million tons of hydrogen, and the company claims the Monzon field holds 5 to 10 million tons within its permits and more than 100 million tons in the region. Natural Hydrogen Energy and HyTerra claim the “first wildcat well targeting natural hydrogen in Nebraska,” the Hoarty well at Project Geneva. HyTerra also holds leases in the Nemaha Ridge in Kansas. The cost advantages of subsurface hydrogen are frequently cited by the early prospectors. For example, the wells in Mali have the potential to generate hydrogen gas at a cost of 50 cents/kg (https://doi.org/10.1016/j.ijhydene.2018.08.193), which is only one-tenth the cost of producing hydrogen via electrolysis using solar, wind, geothermal, or other renewable energy sources. If commercialization and economies of scale pan out, this may become the gold standard for hydrogen energy.

Resumen

IntroductionIn rainfed agricultural systems, sustainable and efficient water management practices are key to improved agricultural productivity and natural resource management. The agricultural system in sub-Saharan Africa (SSA) relies heavily on the availability of rainfall. With the erratic and unreliable rainfall pattern associated with poor and fragile soils, agricultural productivity has remained very low over the years. Much of the SSA agricultural land has been degraded with low fertility as a result of ongoing cultivation and wind and water erosion. This has resulted in an increased food shortage due to the ever-increasing population and land degradation. Better agricultural and nutritional security are further hampered by the lack of reliable access to the available water resources in the subsurface hydrological system.MethodsThis study used socio-economic data from 112 farm households and Boolean and Fuzzy methods to understand farmers' perceptions and identify suitable areas to implement Solar Based Irrigation Systems (SBISs) in the agro-ecologies of Bougouni and Koutiala districts of southern Mali.Results and discussionResults revealed that the usage of SBISs has been recent (4.5 years), majorly (77%) constructed by donor-funded projects mainly for domestic water use and livestock (88%). With regards to irrigation, vegetable production was the dominant water use (60%) enabling rural farm households to gain over 40% of extra household income during the dry season. Results further showed that 4,274 km2 (22%) of the total land area for the Bougouni district, and 1,722 km2 (18%) of the Koutiala district are suitable for solar-based irrigation. The affordability of solar panels in many places makes SBISs to be an emerging climate-smart technology for most rural Malian populations.

Resumen

Objectif : L'objectif de notre étude était d'étudier les effets indésirables liés à l'administration de la Sulfadoxine-Pyrimethamine et Amodiaquine lors de la Chimioprévention du paludisme saisonnier (CPS) de 2015 à 2016, dans dix districts sanitaires du Mali. Population et Méthode : Notre démarche méthodologique était basée sur la collecte des données des effets indésirables à travers une fiche de notification après l'administration des molécules de la Chimio prévention du paludisme saisonnier (Sulfadoxine-Pyrimethamine et Amodiaquine) aux enfants de moins de cinq ans. Les données ont été collectées dans les districts sanitaires de : Nioro du sahel, Nara, Ouelessebougou, Bougouni, Kadiolo, Barouéli, Bla, Ségou, Koro, Tenenkou. Résultats : Durant notre étude, nous avons enregistré 131 cas d'effets indésirables présentés par 104 enfants. Le district sanitaire de Tenenkou a enregistré plus de cas de notification (50%), suivi par Nioro du sahel (13%). Les troubles digestifs étaient les plus représentés soit 83,2%. L'évolution de l'ensemble des effets indésirables étaient favorables pour tous les enfants. Conclusion : Le renforcement du système de pharmacovigilance au Mali à travers la formation continue des personnels sanitaires en vue d'une notification continue des effets indésirables pourrait améliorer la prise en charge des effets indésirables liés aux médicaments de la chimio prévention du paludisme saisonnier.

Resumen

Introduction : Le beurre de karité, riche en acides gras, est devenu un excipient de choix dans l'industrie des produits topiques en raison de ses propriétés uniques. L’objectif de ce travail est d’étudier les propriétés émulsionnantes du beurre de karité produit au Mali. Méthodologie : Il s’est agi d’une étude expérimentale et descriptive sur le beurre de karité de la région de Bougouni. Une méthode de balayage unidimensionnel a été utilisée pour déterminer les proportions optimales de beurre permettant de former des émulsions stables avec de l'eau, sans l'ajout d'agents de stabilisation. Les tests ont varié de 0 à 90% d'eau, avec des incréments de 10%, et ont été répliqués. Résultats : À la fin de la préparation, les émulsions avec des proportions de beurre/eau de 90/10, 80/20, 70/30 et 30/70 ont été stables et fluides 2 heures après l'émulsification. En revanche, les crèmes avec des proportions de 60/40, 50/50 et 40/60 ont été stables et épaisses. Toutes les émulsions ont eu une apparence blanche laiteuse, une consistance semi- solide à solide, et des globules d'une taille de 1 à 5 µm, correspondant à une émulsion moyenne. Toutes avaient été de type E/H. Après 90 jours, les crèmes de proportions 90/10, 80/20, 70/30, 60/40, 50/50 et 40/60 ont été les plus stables, indiquant que le beurre de karité peut incorporer jusqu'à 60% d'eau sans instabilité. Conclusion : le beurre de karité malien, riche en acides oléiques et stéariques, présente des propriétés émulsionnantes et peut incorporer jusqu'à 60% d'eau sans montrer de signes d'instabilité après 90 jours. Ce qui pourrait faire de ce produit, un co-émulsifiant accessible économiquement et permettant de réduire les coûts de fabrication de certains produits.

Resumen

Abstract Background Mass drug administration (MDA) with azithromycin (AZ) is being considered as a strategy to promote child survival in sub-Saharan Africa, but the mechanism by which AZ reduces mortality is unclear. To better understand the nature and extent of protection provided by AZ, we explored the profile of protection by time since administration, using data from a household-randomized, placebo-controlled trial in Burkina Faso and Mali. Methods Between 2014 and 2016, 30 977 children aged 3–59 months received seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine and either AZ or placebo monthly, on 4 occasions each year. Poisson regression with gamma-distributed random effects, accounting for the household randomization and within-individual clustering of illness episodes, was used to compare incidence of prespecified outcomes between SMC+AZ versus SMC+placebo groups in fixed time strata post-treatment. The likelihood ratio test was used to assess evidence for a time-treatment group interaction. Results Relative to SMC+placebo, there was no evidence of protection from SMC+AZ against hospital admissions and deaths. Additional protection from SMC+AZ against malaria was confined to the first 2 weeks post-administration (protective efficacy (PE): 24.2% [95% CI: 17.8%, 30.1%]). Gastroenteritis and pneumonia were reduced by 29.9% [21.7; 37.3%], and 34.3% [14.9; 49.3%], respectively, in the first 2 weeks postadministration. Protection against nonmalaria fevers with a skin condition persisted up to 28 days: PE: 46.3% [35.1; 55.6%]. The benefits of AZ-MDA are broad-ranging but short-lived. To maximize impact, timing of AZ-MDA must address the challenge of targeting asynchronous morbidity and mortality peaks from different causes.
