    Nutritional treatment of children with uncomplicated severe acute malnutrition (SAM) is based on ready-to-use therapeutic foods (RUTF). With treatment provided at community level, children could have access to other foods, and a reduction in the dose of RUTF could further increase dietary diversity during treatment. We assessed the dietary diversity score (DDS), the minimum dietary diversity (MDD), the minimum meal frequency (MMF) and the minimum acceptable diet (MAD) of 459 infants and young children aged 6-23 months being treated for SAM with different doses of RUTF. We also investigated the factors associated with DDS. Dietary intake was estimated using a single 24-h multipass dietary recall, 1 month after starting treatment, from December 2016 to August 2018. The DDS was calculated on the basis of eight food groups. Differences between children receiving the reduced RUTF and the standard RUTF dose and factors associated with DDS were assessed by Poisson and logistic regression models. RUTF dose was not associated with DDS (4.07 +/- 1.25 for reduced RUTF and 4.01 +/- 1.26 for standard RUTF; P = 0.77). Food groups most consumed by children were grains, roots or tubers (96%) and legumes and nuts (72%). Eggs consumption was low (3%). DDS was positively associated with child's age, mother's education, household wealth index, urban residence and rainy season. The present findings show that children with SAM consumed a variety of foods during treatment in addition to the RUTF ration prescribed to them. Reducing the dose of RUTF during SAM treatment did not impact DDS

    Les malformations congénitales par anomalie de position et de développement des arcs brachiaux primitifs représentent 1% des anomalies congénitales cardio-vasculaires. Nous rapportons le cas rare d'un nourrisson de 22 mois, né par voie basse d'une grossesse menée à terme qui a présenté une dyspnée intermittente depuis la naissance associée à une toux. L'angio-scanner cervico-thoracique a permis d'objectiver un arc aortique droit et une artère sub-clavière gauche pré-trachéo-oesophagienne prenant en pince l'œsophage et la trachée à environ 15 mm au-dessus de la carène entrainant une sténose d'environ 70% de la trachée sur une hauteur de 16 mm. Cette malformation complexe représente un type rare d'anomalie de l'arc aortique avec une variante inhabituelle du trajet de l'artère sub-clavière gauche. Elle pose un problème diagnostique et de traitement dans notre contexte du fait des difficultés d'accessibilité au scanner et à la chirurgie

    Background: Ready-to-use therapeutic foods (RUTF) are designed to cover the daily nutrient requirements of children with severe acute malnutrition (SAM). However, with the transfer of uncomplicated SAM care from the hospital environment to the community level, children will be able to consume complementary and family foods (CFF) in addition to RUTF, and this might decrease the quantity of RUTF needed for recovery. Objectives: Using an individually randomized clinical trial, we investigated the effects of a reduced RUTF dose on the daily energy and macronutrient intakes, the proportion of energy coming from CFF, and the mean probability of adequacy (MPA) of intake in 11 micronutrients of 516 children aged 6–59 mo who were treated for SAM in Burkina Faso. Methods: The data were collected using a single 24-h multipass dietary recall, 1 mo after starting treatment, from December 2016 to August 2018, repeated on a subsample of 66 children. Differences between children receiving the reduced RUTF (intervention arm) and those receiving standard RUTF (control arm) were assessed by linear mixed models. Results: Daily energy intake was lower (P < 0.01) in the intervention arm (mean ± SD 1321 ± 339 kcal) than in the control arm (1467 ± 319 kcal). CFF contributed to 40% of the daily energy intake in the intervention and 35% in the control arm. The MPA for 11 micronutrients was 0.89 ± 0.1 in the intervention arm and 0.95 ± 0.07 in the control arm (P = 0.06). Conclusions: Reducing the dose of RUTF during SAM treatment had a negative impact on daily energy intake of the children. Despite this, children covered their recommended energy intake. The energy intake coming from CFF was similar between arms, suggesting that children’s feeding practices did not change due to the reduction in RUTF in this context. This trial was registered at the IRSCTN registry as ISRCTN5003902

    Although soil microbial biomass (MBC) comprises less than 5% of soil organic matter, it responds rapidly to changes in soil management practices and, therefore, is generally used as early indicators of changes in soil carbon. The objective of this study was to evaluate the effects of tillage practices (conventional tillage and no-tillage) and fertiliser types (synthetic, organic, and no fertiliser) on soil MBC. The field experiment, located in Bue, Southwest region of Cameroon. The experiment was carried out in a split-plot design with three replications with tillage systems as main plots and fertiliser types as sub-plots. Soil samples were collected at 0–15 cm depth at an interval of 4 (early season), 8 (mid-season) and 12 (late season) weeks during the 2020 and 2021 minor and major growing seasons respectively, for the determination of soil MBC by the chloroform fumigation and extraction method. The findings of the study showed that the main effect of tillage practice and fertiliser types was unsignificant (p>0.05) in the 2020 and 2021 study season throughout the sampling period. Plots under zero tillage with control experiments (No.Till:CON) recorded the highest soil MBC in the 2020 season (201 kg-1 respectively) while in the 2021 season, plots under zero tillage with organic fertilisation (No.Till:ORG) recorded the highest (400.4 mg kg-1) soil MBC. Soil MBC was higher in the 2021 season than in the 2020 season. These findings suggest that the use of compost in combination with either conventional tillage or no-tillage in farms in the study area could potentially enhance soil MBC

    Vitamin B12 Status before and after Outpatient Treatment of Severe Acute Malnutrition in Children Aged 6–59 Months : A Sub-Study of a Randomized Controlled Trial in Burkina Faso

    Severe acute malnutrition (SAM) is treated with ready-to-use therapeutic foods (RUTF) containing a vitamin–mineral premix. Yet little is known about micronutrient status in children with SAM before and after treatment. We aimed to investigate vitamin B12 status in children with uncomplicated SAM, aged 6–59 months in Burkina Faso, before and after treatment with a standard or a reduced dose of RUTF. Blood samples were collected at admission and discharge. Serum B12 was determined with microbiological assay and serum methylmalonic acid (MMA) and total homocysteine (tHcy) were analyzed with gas chromatography-tandem mass spectrometry. B12 status was classified using the combined indicator (3cB12). Among 374 children, the median [interquartile range] age was 11.0 [7.7–16.9] months, and 85.8% were breastfed. Marked or severe B12 deficiency, as judged by 3cB12, decreased from 32% to 9% between admission and discharge (p < 0.05). No differences in B12 status following treatment with either standard (n = 194) or reduced (n = 180) doses of RUTF were observed. Breastfed children showed a lower B12 status (3cB12) than non-breastfed ones (−1.10 vs −0.18, p < 0.001 at admission; −0.44 vs 0.19; p < 0.001 at discharge). In conclusion, treatment of SAM with RUTF improved children’s B12 status but did not fully correct B12 deficiency.Peer reviewe

    Onchocerciasis prevalence, human migration and risks for onchocerciasis elimination in the Upper Mouhoun, Nakambé and Nazinon river basins in Burkina Faso.

    Historically, the whole of Burkina Faso was considered to be endemic for onchocerciasis (except a small area in the far north of the country) with prevalence rates 60-80%, but all endemic areas were included in the World Health Organisation Onchocerciasis Control Programme, which operated a system of vector control by larviciding beginning in 1974. In Burkina Faso larviciding had been phased out by 1989 when it was considered that onchocerciasis had been reduced to levels below the transmission breakpoint (and any residual infections would disappear without further intervention). There was never any mass drug administration against onchocerciasis in Burkina Faso, except in the Bougouriba and Comoé river basins (from 1996 and 2011 to present respectively) because in each of these two areas there was a resurgence of infection, and in parts of the Nakambé River basin and Sissili River basin from 1992 to 1998. However, mass drug administration with ivermectin was also phased in across the whole country starting in 2000 using ivermectin against lymphatic filariasis and is currently being phased out (depending upon the epidemiological parameters). In this publication we report a new epidemiological survey for onchocerciasis which was carried out in 2014 in the Upper Mouhoun, Nakambé and Nazinon river basins in Burkina Faso to evaluate the prevalence and intensity of infection of onchocerciasis. A total of 11,195 people from 61 villages were examined across these three river basins, and onchocerciasis prevalence by skin-snip was below 5% in all villages, below 1% in 57 villages (93% of 61 villages) and zero in 47. In the 14 villages with positive skin snips, prevalence figures ranged from 0.31% to 3.50%. During the survey 31 infected individuals were found. All of them were Burkinabé, of whom 30 had a recent history of residence in Côte d'Ivoire (with a range of 0.5 to 73 microfilariae per skin-snip from two snips per person) and only one had no history of migration and presumably had an autochthonous infection (mean of 0.5 microfilariae per skin snip from two snips). According to parasitological indicators listed by the World Health Organization African Programme for Onchocerciasis Control in 2010, the situation for onchocerciasis was considered to be satisfactory in all three river basins and probably below the transmission threshold, in which case the disease should disappear naturally without the need for further intervention in the absence of continuing immigration. However, the results clearly indicate that infected persons coming from endemic zones of Côte d'Ivoire are settling in small communities which are otherwise nearly free from onchocerciasis in Burkina Faso. They are thus a source of continuing re-introduction of the parasite into the basins and could be a risk for the achievement of onchocerciasis elimination in all three basins. This would justify the continuation of periodic epidemiological surveys to monitor the possible recrudescence of the disease, and entomological (vector) surveys should be undertaken to assess and monitor the residual transmission

    Antimicrobial Activity of Bacterial Strains Isolated from Macrotermes belli-cosus Termite Mound

    Natural environments like termite mounds can be a reservoir for novel microbial strains and antimicrobial metabolite producers. Hence, this study aimed to investigate the antimicrobial activities of bacterial strains isolated from Macrotermes bellicosus (M. bellicosus) termite mound materials. These materials were sampled from active termite mounds in the Somgandé botanic reserve in Ouagadougou, Burkina Faso. The study collected sixty-three bacterial isolates and assessed their antimicrobial activity against several pathogenic bacteria (Bacillus subtilis, Escherichia coli, Micrococcus luteus, Pseudomonas aeruginosa and Staphylococcus aureus) and two pathogenic fungi (Aspergillus niger and Candida albicans). The dual culture and paper disc diffusion assays revealed that 10 isolates (5 bacteria and 5 actinobacteria) inhibited the growth of at least one pathogenic microorganism. In comparison, four isolates inhibited both Gram-positive and Gram-negative bacteria. Overall, isolates MBm2, MBm8 (bacteria), and MBm26 (actinobacterium) displayed better antibacterial- and antifungal activity against all tested pathogenic microorganisms. It is germane to indicate here that several typical bacteria and actinobacteria isolated from the M. bellicosus termite mound materials were good producers of antibacterial and antifungal agents. Thus, future studies could further characterize these isolates and optimize their growth for producing antimicrobial compounds. The bioactive compounds should also be identified for further biotechnological applications
