Complementary feeding practices and associated factors of dietary diversity among uncomplicated severe acute malnourished children aged 6-23 months in Burkina Faso

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

Children with Moderate Acute Malnutrition with No Access to Supplementary Feeding Programmes Experience High Rates of Deterioration and No Improvement: Results from a Prospective Cohort Study in Rural Ethiopia

Background: Children with moderate acute malnutrition (MAM) have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs) for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations. Methods: We defined MAM as mid-upper arm circumference (MUAC) of ≥11.0cm and <12.5cm with no bilateral pitting oedema to include Ethiopian government and World Health Organisation cut-offs. We prospectively surveyed 884 children aged 6–59 months living with MAM in a rural area of Ethiopia not eligible for a supplementary feeding programme. Weekly home visits were made for seven months (28 weeks), covering the end of peak malnutrition through to the post-harvest period (the most food secure window), collecting anthropometric, socio-demographic and food security data. Results: By the end of the study follow up, 32.5% (287/884) remained with MAM, 9.3% (82/884) experienced at least one episode of SAM (MUAC <11cm and/or bilateral pitting oedema), and 0.9% (8/884) died. Only 54.2% of the children recovered with no episode of SAM by the end of the study. Of those who developed SAM half still had MAM at the end of the follow up period. The median (interquartile range) time to recovery was 9 (4–15) weeks. Children with the lowest MUAC at enrolment had a significantly higher risk of remaining with MAM and a lower chance of recovering. Conclusions: Children with MAM during the post-harvest season in an area not eligible for SFP experience an extremely high incidence of SAM and a low recovery rate. Not having a targeted nutrition-specific intervention to address MAM in this context places children with MAM at excessive risk of adverse outcomes. Further preventive and curative approaches should urgently be considered

Adequacy of nutrient intakes of severely and acutely malnourished children treated with different doses of ready-to-use therapeutic food in Burkina Faso

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

Aspect tdm d’une anomalie de l’arc aortique: variante de Nehausser?

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

Impact of sustainable soil management practices on soil microbial biomass carbon: Implications for climate change mitigation

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

Revealing the Most Vulnerable Groups: Courtesy Stigma in Caregivers of Autistic Persons in Quebec

IntroductionCaregivers of autistic persons often face “courtesy stigma,” a phenomenon by which caregivers experience stigma because of their association with a person whose disability may be stigmatized. Understanding the repercussions of this stigma is crucial not only for caregivers’ mental health but also for the quality of care provided to their dependent. This study aimed to explore courtesy stigma among caregivers of autistic persons in Quebec, examining its prevalence and impact in order to identify groups that are particularly susceptible to negative outcomes.MethodsThis study used a cross-sectional online survey methodology employing quota sampling to collect responses from 194 participants. Data were collected using a computer-assisted web interview (CAWI) platform. The impact of courtesy stigma was measured in terms of care burden, mental health, and overall well-being of caregivers.ResultsThe findings revealed that caregivers frequently experience rejection, isolation, and work-related challenges. Notably, caregivers’ health was below average with the lowest reported health outcomes in Quebec. The caregivers who are the most vulnerable to negative outcomes included female caregivers, those aged 45 or older, financially strained households, caregivers of children requiring elevated levels of support, caregivers who isolated due to their autistic dependents, and those who experienced stigmatization directed at themselves or their children in the form of rejection.Interestingly, 60% of respondents reported that the caregiving burden was “not at all” to “somewhat” difficult, raising questions about factors that may mitigate caregiving challenges over time.ConclusionNegative outcomes from courtesy stigma vary depending on certain risk factors and individual characteristic. This study underscores the need for targeted public policies and interventions, particularly for those at a higher risk of experiencing the negative effects of courtesy stigma on the burden of care, overall health, and mental health. By tailoring resources and support for these priority groups, we can better address the challenges faced by families of autistic persons

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
