Aetiology of diarrhoea in children aged zero to nine years in low- and middle-income countries
Antibiotic resistance trends for common bacterial aetiologies of childhood diarrhoea in low- and middle-income countries
Derivation and validation of a novel risk assessment tool to identify children aged 2–59 months at risk of hospitalised pneumonia-related mortality in 20 countries
INTRODUCTION: Existing risk assessment tools to identify children at risk of hospitalised pneumonia-related mortality have shown suboptimal discriminatory value during external validation. Our objective was to derive and validate a novel risk assessment tool to identify children aged 2-59 months at risk of hospitalised pneumonia-related mortality across various settings. METHODS: We used primary, baseline, patient-level data from 11 studies, incl…
Importance of breastfeeding and complementary feeding for management and prevention of childhood diarrhoea in low- and middle-income countries
Background: Early and exclusive breastfeeding have been shown to protect young infants from all-cause and diarrhoea-related mortality. Ideally breastfeeding should be initiated within the first hour of birth. Despite efforts to increase rates of early and exclusive breastfeeding in low- and middle-income countries (LMICs), challenges with uptake remain. This analysis reviews trends in early and exclusive breastfeeding, and the impact of infant fe…
Measuring coverage and quality of supportive care for inpatient neonatal infections
Background: An estimated 7 million episodes of severe newborn infections occur annually worldwide, with half a million newborn deaths, most occurring in low- and middle-income countries. Whilst injectable antibiotics are necessary to treat the infection, supportive care is also crucial in ending preventable mortality and morbidity. This study uses multi-country data to assess gaps in coverage, quality, and documentation of supportive care, consid…
Community-based amoxicillin treatment for fast breathing pneumonia in young infants 7–59 days old
Introduction Young infants 7–59 days old with fast breathing pneumonia presented to a primary level health facility receive a 7-day course of amoxicillin as per the WHO guideline. However, community-level health workers (CLHW) are not allowed to treat these infants. This trial evaluated the community level treatment of non-hypoxaemic young infants with fast breathing pneumonia by CLHWs. Methods This cluster-randomised, open-label, non-inferiority…
External validation of the Risc, Risc-Malawi, and PERCH clinical prediction rules to identify risk of death in children hospitalized with pneumonia
BACKGROUND: Existing scores to identify children at risk of hospitalized pneumonia-related mortality lack broad external validation. Our objective was to externally validate three such risk scores. METHODS: We applied the Respiratory Index of Severity in Children (RISC) for HIV-negative children, the RISC-Malawi, and the Pneumonia Etiology Research for Child Health (PERCH) scores to hospitalized children in the Pneumonia REsearch Partnerships to …
An analysis of clinical predictive values for radiographic pneumonia in children
INTRODUCTION: Healthcare providers in resource-limited settings rely on the presence of tachypnoea and chest indrawing to establish a diagnosis of pneumonia in children. We aimed to determine the test characteristics of commonly assessed signs and symptoms for the radiographic diagnosis of pneumonia in children 0-59 months of age. METHODS: We conducted an analysis using patient-level pooled data from 41 shared datasets of paediatric pneumonia. We…
Iron/folic acid supplementation during pregnancy prevents neonatal and under-five mortality in Pakistan
BACKGROUND: Several epidemiological studies from low- and middle-income countries have reported a protective effect of maternal antenatal iron/folic acid (IFA) on childhood mortality. OBJECTIVE: The current study aimed to evaluate the effect of maternal antenatal IFA supplementation on childhood mortality in Pakistan. DESIGN: A propensity score-matched sample of 8,512 infants live-born within the 5 years prior to interview was selected from the p…
