<h2>Summary</h2><h3>Background</h3> WHO recommends gametocytocidal, single low-dose primaquine for blocking the transmission of <i>Plasmodium falciparum</i>; however, safety concerns have hampered implementation this strategy in sub-Saharan Africa. We aimed to investigate age-dosed, children from Uganda and Democratic Republic Congo. <h3>Methods</h3> conducted randomised, double-blind, placebo-controlled, non-inferiority trial at Mbale Regional Referral Hospital, Mbale, Uganda, Kinshasa...

BackgroundThe TRACT trial established the timing of transfusion in children with uncomplicated anaemia (haemoglobin 4–6 g/dL) and optimal volume (20 vs 30 mL/kg whole blood or 10 15 red cell concentrates) for admitted to hospital severe <6 on day 28 mortality (primary endpoint). Because data safety components are scarce, we conducted a secondary analysis examine efficacy different pack types (whole clinical outcomes.MethodsThis study is restricted those who received an immediate (using...

<ns3:p><ns3:bold>Background: </ns3:bold>Changes in intestinal mucosal integrity and gut microbial balance occur severe acute malnutrition (SAM), resulting treatment failure adverse clinical outcomes (gram-negative sepsis, diarrhoea high case-fatality). Transient lactose intolerance, due to loss of brush border lactase, also complicates SAM, thus milk based feeds may not be optimal for nutritional rehabilitation. Since the epithelial barrier can supported by short chain fatty acids, derived...

Abstract Background Children hospitalised with severe malnutrition (SM) have high mortality and relapse/readmission rates. Current milk-based formulations targets restoring ponderal growth but not modification of gut barrier integrety or microbiome which increase risk gram-negative sepsis poor outcomes. Objectives We propose that legume-based feeds rich in fermentable carbohydrates will promote better health improve overall Methods conducted at Mbale Regional Referral Hospital, Uganda an...

Single low-dose primaquine (SLDPQ) effectively blocks the transmission of Plasmodium falciparum malaria, but anxiety remains regarding its haemolytic potential in patients with glucose-6-phopshate dehydrogenase (G6PD) deficiency. We, therefore, examined independent effects several factors on haemoglobin (Hb) dynamics falciparum-infected children a particular interest SLDPQ and G6PD status.This randomised, double-blind, placebo-controlled, safety trial was conducted Congolese Ugandan aged 6...
