Materials and MethodsThis was an analytical, descriptive, and retrospective study conducted in patients aged 0 to 18 years, admitted between August 2023 and March 2025, ...

BackgroundThe epidemiology of suspected pediatric meningoencephalitis has shifted in the era of conjugate vaccines and multiplex PCR diagnostics, with viral pathogens now predominating over bacterial causes. Updated epidemiologic data are essential to adapt diagnostic and therapeutic algorithms to current clinical practice. MethodsThis retrospective single-center study included children and adolescents <18 years who underwent lumbar puncture with cerebrospinal fluid multiplex PCR for suspected ...

ObjectivesVentilator-associated pneumonia (VAP) is a significant complication in pediatric patients with severe bronchiolitis undergoing mechanical ventilation (MV) in pediatric intensive care units (PICUs). The role of respiratory microbiota in VAP development remains underexplored in this vulnerable population. This study aimed to characterize respiratory microbiota in critically ill children with severe bronchiolitis receiving critical care and identify microbial patterns associated with VAP....

BackgroundChildren with tracheostomies experience frequent and recurrent acute respiratory infections (ARIs). While cultured respiratory pathogens can inform ARI diagnosis, it is unknown if their presence in the airway affects future ARI risk. ObjectiveTo identify predictors of frequent (3+) ARIs within 36 months of tracheostomy. MethodsWe conducted a single-center, retrospective cohort study of children with tracheostomies placed between 2010-2016. Medical records were reviewed for each encou...

ImportanceCurrent guidelines from the World Health Organization, Centers for Disease Control and Prevention, and Academy of Breastfeeding Medicine recommend discarding all milk remaining in bottles immediately after infant feeding. However, these recommendations lack supporting microbiological evidence from studies of actual infant feeding, imposing substantial financial and emotional burden on the 78 million families worldwide who bottle-feed their infants. ObjectiveTo determine (1) the financ...

Background and objectivesCeftazidime-Avibactam (CAZ-AVI) is one of the last options to treat Enterobacteriales and Pseudomonas aeruginosa carbapenem-resistant. We aim to describe the susceptibility profile of bloodstream isolates of Enterobacterales and Pseudomonas aerunosa to ceftazidime-avibactam (CAZ-AVI) among strains resistant to third- and fourth-generation cephalosporins and/or carbapenems. MethodsWe conducted a retrospective descriptive study in two pediatric hospitals of Rio de Janeiro...

BackgroundAsthma is a frequent comorbidity in children with sickle cell disease and has been associated with an increased risk of acute complications, particularly vaso-occlusive crises and acute chest syndrome. However, determinants of clinical severity among children with sickle cell disease and confirmed asthma remain poorly characterized, especially in tropical settings. This study aimed to identify factors associated with clinical severity in this population. MethodsWe conducted an observa...

BackgroundNeonatal jaundice management increasingly relies on transcutaneous bilirubinometry (TcB), yet discrepancies with serum bilirubin (TSB) have limited its clinical reliability. This study introduces Skin Residual Bilirubin Volume (SRBV) as a physiologically grounded framework to enhance TcB interpretation. ObjectiveTo evaluate SRBV as an explanation for TcB-TSB discordance and assess whether incorporating SRBV improves the interpretability and reliability of TcB measurements during diagn...

BackgroundRecurrent urinary tract infection (rUTI) is a major diagnostic and management challenge. Dysregulated innate immune responses, including antimicrobial peptides and cytokines, may underlie UTI susceptibility. This study investigates whether urinary concentrations of antimicrobial peptides and cytokines differ in children and adolescents with a history of rUTI and whether they can accurately classify rUTI status. MethodsUrine samples were collected from 42 girls and adolescent females w...

BackgroundPediatric eczema is a highly prevalent condition that often causes substantial suffering among affected children and their families. Numerous modifiable lifestyle and environmental risk factors for the condition have been identified, although these risk factors and related interventions have generally been studied in isolation. The goal of this study was to evaluate the effects of an integrative program for parents of children with eczema that simultaneously addressed multiple lifestyl...

BackgroundPediatric poisonings are a significant cause of emergency admissions, often linked to accessible household toxins. This study investigates the epidemiological patterns, clinical presentations, and management strategies at a tertiary care hospital in Algiers, Algeria. MethodsA retrospective descriptive analysis was conducted on anonymized pediatric poisonings cases. Variables included age, sex, type of ingestion, intent (accidental vs. voluntary), substances involved, endoscopic findin...

BackgroundPre-referral stabilization is a critical yet neglected component of pediatric emergency care in low-resource settings. It involves delivering life-saving interventions-- such as airway management, oxygen therapy, fluids, glucose, and anticonvulsants at the initial point of care before referral. The WHOs ETAT Guidelines emphasize the prompt recognition and management of life-threatening conditions in children to reduce mortality. Despite Tanzanias adoption of ETAT, the extent to which p...

BackgroundInfections are the leading cause of non-relapse mortality in pediatric hematopoietic cell transplant (HCT) recipients. Up to 90% of bacteremias in these patients originate from gut microbiome organisms. However, selection for resistance genes, such as Extended-spectrum {beta}-lactamase (ESBL), in these patients gut microbiomes remains poorly understood. MethodsStools were prospectively collected from pediatric HCT recipients at multiple centers (n=133 patients, five centers) on the da...

BackgroundTranslocation of bacteria across the intestinal barrier has been postulated to contribute to mortality among severely malnourished children. Pancreatic enzymes (PE) and bile acids (BA) have anti-bacterial properties in the small intestine, but severe malnutrition is associated with impaired exocrine pancreatic and hepatobiliary functions. We evaluated whether ancillary treatment with PE and BA improves survival in hospitalized, acutely ill, severely malnourished children. Methods and ...

BackgroundPediatric long COVID is associated with substantial symptom burden, yet evidence-based pharmacologic treatments remain limited. Low-dose naltrexone (LDN) has been proposed as a potential symptomatic therapy, but data in pediatric populations is lacking. MethodsWe conducted a retrospective analysis of pediatric and young adult patients ([&le;]25 years) with a clinical diagnosis of long COVID who were prescribed LDN between July 2020 and July 2025 at three multidisciplinary pediatric lo...

Dysglycemia is a critical metabolic disturbance associated with mortality in acutely ill children, yet its burden may be underrecognized in low-income settings due to reliance on single point-of-care measurements. Using continuous glucose monitoring (CGM), we aimed to characterize glucose patterns in acutely ill children of different anthropometric status. MethodsChildren aged 2-23 months admitted with acute illness were prospectively recruited from two hospitals in Bangladesh and Malawi. Clini...

IntroductionPediatric acute appendicitis (PAA) remains challenging to diagnose despite existing diagnostic scores. The BIDIAP index is a three-item diagnostic tool with very high discriminative performance in a derivation cohort. This study aimed to prospectively and externally validate the BIDIAP index in a multicenter pediatric population. Material and MethodsWe conducted a prospective, multicenter observational study across four tertiary pediatric centers, enrolling children presenting with ...

Abnormal respiratory microbiomes are reported in children with artificial airways, yet the timing and persistence of these disruptions have not been defined in infants following new tracheostomy placement. We conducted a prospective longitudinal study to characterize airway microbiome dynamics following new tracheostomy placement during early life, a critical period for microbiome development. Fifteen hospitalized infants <=12 months contributed 84 tracheal aspirate samples collected from day 1 ...

Background and ObjectivesCurrent potassium reference intervals for neonates fail to account for sampling method differences and prematurity-related factors, leading to unnecessary resampling and interventions. We aimed to establish sampling-specific potassium reference intervals for term and preterm neonates using comprehensive electronic health record data. MethodsWe analyzed 195 606 blood gas measurements from 10 290 neonates (2007-2024) at a tertiary neonatal intensive care unit. After ex-cl...

BackgroundCongenital anomalies are among the leading causes of neonatal morbidity and mortality, particularly in low- and middle-income countries. Early detection through newborn screening improves outcomes, yet little is known about the screening practices of healthcare professionals (HCPs) in Ethiopia. In our setting, many children with congenital malformations are not identified at birth and present later, after being discharged from the birth facility. MethodsA cross-sectional study was con...
