Longitudinal serological response to Sars-CoV-2 among rohingya refugees in cox’s bazar, Bangladesh
This study demonstrates robust antibody responses following natural SARS-CoV-2 infection and a marked rise-but rapid decline-of vaccine-induced immunity among Rohingya refugees. The findings highlight the need for timely booster doses, strengthened vaccination coverage, and continued serological monitoring to maintain protective immunity in high-density humanitarian settings. These insights can support targeted public health interventions and pan…
Streptococcus pneumoniae carriage, antimicrobial resistance, and serotype distribution in children and adults from Paraguay in the post-vaccinal era
Introduction: , including pneumonia and meningitis, are a leading cause of morbidity and mortality, especially in low-and lower middle-income countries (LMICs) worldwide. Most reviews highlight the geographical differences in serotype replacement and antibiotic resistance observed through invasive pneumococcal disease (IPD) surveillance, predominantly in high-income countries; however, data from many LMICs remain limited or poorly characterized. …
Development and validation of a novel clinical risk score to predict hypoxaemia in children with pneumonia using the WHO PREPARE dataset
BACKGROUND: Hypoxaemia predicts mortality at all levels of care, and appropriate management can reduce preventable deaths. However, pulse oximetry and oxygen therapy remain inaccessible in many primary care health facilities. We aimed to develop and validate a simple risk score comprising commonly evaluated clinical features to predict hypoxaemia in 2-59-month-old children with pneumonia. METHODS: Data from seven studies conducted in five countri…
Epidemiology and serotype distribution of Streptococcus pneumoniae carriage among influenza-like illness cases in metropolitan Vientiane, Lao PDR
Background Data on the epidemiology of Streptococcus pneumoniae among influenza-like illness (ILI) cases, particularly in low- and middle-income countries are scarce. This study assessed the prevalence, risk factors and serotype distribution of S. pneumoniae carriage among ILI cases in metropolitan Vientiane, Lao People's Democratic Republic. The 13-valent pneumococcal conjugate vaccine (PCV13) was introduced among infants in October 2013. Method…
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…
Assembling a global database of child pneumonia studies to inform WHO pneumonia management algorithm
Background: The existing World Health Organization (WHO) pneumonia case management guidelines rely on clinical symptoms and signs for identifying, classifying, and treating pneumonia in children up to 5 years old. We aimed to collate an individual patient-level data set from large, high-quality pre-existing studies on pneumonia in children to identify a set of signs and symptoms with greater validity in the diagnosis, prognosis, and possible trea…
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 …
