Maitland K, Olupot-Olupot P, Kiguli S, et al., 2019, Co-trimoxazole or multi-mineral multi-vitamins to improve post-discharge outcomes following severe anaemia in African children: a randomised controlled trial, The Lancet Global Health, Vol: 7, Pages: e1435-e1447, ISSN: 2214-109X
Background: Severe anaemia (haemoglobin<6g/dl) is a leading cause of paediatric admission inAfrica; post-discharge outcomes remain poor with high 6-month mortality (8%) and re-admission(17%). This trial aimed to investigate pragmatic post-discharge interventions that might improveoutcomes.Methods: Within the factorial open-label TRACT trial, Ugandan and Malawian children aged 2months-12 years with severe anaemia (haemoglobin <6g/dl) at hospital admission wererandomised (using sequentially-numbered envelopes linked to a second set of non-sequentiallynumbered allocations, stratified by centre and severity) to enhanced nutritional supplementationwith iron and folate-containing multi-vitamin multi-mineral supplements (MVMM) or iron/folateat treatment doses (usual care), and to cotrimoxazole versus no cotrimoxazole, both given for 3months post-discharge. Separately-reported randomisations investigated transfusionmanagement. The primary outcome was 180-day mortality analysed by intention-to-treat; followup was to 180-days (completed).Findings: 3983 eligible children were randomised and followed for 180-days [164(4%) lost-tofollow-up]. Treatment was initiated in 1901(95%) MVMM, 1911(96%) iron/folate and 1922(96%)cotrimoxazole. By day-180, 166(8%) MVMM vs 169(9%) iron/folate had died (hazardratio(HR)=0.97 (95% CI 0.79-1.21); p=0.81) and 172(9%) cotrimoxazole vs 163(8%) nocotrimoxazole had died (HR=1.07 (95% CI 0.86-1.32); p=0.56). No evidence was seen ofinteractions between these randomisations or with transfusion randomisations (p>0.2). By day180, 489(24%) MVMM vs 509(26%) iron/folate had experienced one or more SAEs (HR=0.95 (0.84-1.07), p=0.40) and 500(25%) cotrimoxazole vs 498(25%) no cotrimoxazole (HR=1.01 (0.89,1.15)p=0.85). Most SAEs were readmissions, occurring in 692(17%) children (175(4%) with ≥2 readmissions).Interpretation: Neither enhanced supplementation with MVMM versus iron/folate treatment orcotrimoxazole prophylaxis improved 6-month survival.

Consortium H, Drake L, Frost G, et al., 2019, Health outcomes in Undernutrition: the role of Nutrients, Gut dysfunction and the gut microbiome (HUNGer), Health outcomes in Undernutrition: the role of Nutrients, Gut dysfunction and the gut microbiome (HUNGer), Publisher: Imperial College London
The HUNGer consortium is comprised of a multi-disciplinary, multi-national consortium of world leading researchers, with expertise in physiology and nutrition, through to clinical research, public health and agriculture in LMIC settings. The HUNGer consortium was awarded the MRC Confidence in Global Nutrition and Health award in 2018.The HUNGer consortium is developing a programme of work that will directly address United Nations Sustainable Development Goal 2 (SDG-2): End hunger, achieve food security and improve nutrition, and promote sustainable agriculture. We believe there are a number of critical unanswered questions regarding the role of the gut in undernutrition, which if answered could significantly improve the effective management and prevention of undernutrition.The following document represents the consensus opinion of the HUNGer consortium concerning the key challenges that currently limit the effective management and prevention of undernutrition and the most promising potential solutions.
Walsh K, Calder N, Olupot-Olupot P, et al., 2018, Modifying Intestinal Integrity and MicroBiome in Severe Malnutrition with Legume-Based Feeds (MIMBLE 2.0): protocol for a phase II refined feed and intervention trial, Wellcome Open Research, Vol: 3, ISSN: 2398-502X
Background: Changes in intestinal mucosal integrity and gut microbial balance occur in severe acute malnutrition (SAM), resulting in treatment failure and adverse clinical outcomes (gram-negative sepsis, diarrhoea and high case-fatality). Transient lactose intolerance, due to loss of intestinal brush border lactase, also complicates SAM, thus milk based feeds may not be optimal for nutritional rehabilitation. Since the gut epithelial barrier can be supported by short chain fatty acids, derived from microbiota fermentation by particular fermentable carbohydrates, we postulated that an energy-dense nutritional feed comprising of legume-based fermentable carbohydrates, incorporated with lactose-free versions of standard World Health Organization (WHO) F75/F100 nutritional feeds will enhance epithelial barrier function in malnourished children, reduce and promote resolution of diarrhoea and improve overall outcome. Methods: We will investigate in an open-label trial in 160 Ugandan children with SAM, defined by mid-upper arm circumference <11.5cm and/or presence of kwashiorkor. Children will be randomised to a lactose-free, chickpea-enriched feed containing 2 kcal/ml, provided in quantities to match usual energy provision (experimental) or WHO standard treatment F75 (0.75 kcal/ml) and F100 (1 kcal/ml) feeds on a 1:1 basis, conducted at Mbale Regional Referral Hospital nutritional rehabilitation unit. The primary outcomes are change in MUAC at day 90 and survival to day 90. Secondary outcomes include: i) moderate to good weight gain (>5 g/kg/day), ii) de novo development of diarrhoea (>3 loose stools/day), iii) time to diarrhoea resolution (if >3 loose stools/day), and iv) time to oedema resolution (if kwashiorkor) and change in intestinal biomarkers (faecal calprotectin). Discussion: We hypothesize that, if introduced early in the management of malnutrition, such lactose-free, fermentable carbohydrate-based feeds, could safely and cheaply improve global outco
Maitland K, 2016, Validation of triple pass 24-hour dietary recall in Ugandan children by simultaneous weighed food assessment, BMC Nutrition, Vol: 2, Pages: 1-9, ISSN: 2055-0928
BackgroundUndernutrition remains highly prevalent in African children, highlighting the need for accurately assessing dietary intake. In order to do so, the assessment method must be validated in the target population. A triple pass 24 h dietary recall with volumetric portion size estimation has been described but not previously validated in African children. This study aimed to establish the relative validity of 24-h dietary recalls of daily food consumption in healthy African children living in Mbale and Soroti, eastern Uganda compared to simultaneous weighed food records.MethodsQuantitative assessment of daily food consumption by weighed food records followed by two independent assessments using triple pass 24-h dietary recall on the following day. In conjunction with household measures and standard food sizes, volumes of liquid, dry rice, or play dough were used to aid portion size estimation. Inter-assessor agreement, and agreement with weighed food records was conducted primarily by Bland-Altman analysis and secondly by intraclass correlation coefficients and quartile cross-classification.ResultsNineteen healthy children aged 6 months to 12 years were included in the study. Bland-Altman analysis showed 24-h recall only marginally under-estimated energy (mean difference of 149 kJ or 2.8 %; limits of agreement −1618 to 1321 kJ), protein (2.9 g or 9.4 %; −12.6 to 6.7 g), and iron (0.43 mg or 8.3 %; −3.1 to 2.3 mg). Quartile cross-classification was correct in 79 % of cases for energy intake, and 89 % for both protein and iron. The intraclass correlation coefficient between the separate dietary recalls for energy was 0.801 (95 % CI, 0.429–0.933), indicating acceptable inter-observer agreement.ConclusionsDietary assessment using 24-h dietary recall with volumetric portion size estimation resulted in similar and acceptable estimates of dietary intake compared with weighed food records and thus is considered a valid method for daily dietary in
