BACKGROUND Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection and hospitalisations in infants worldwide. The primary analyses of HARMONIE showed that nirsevimab reduced infant hospitalisations due to RSV-associated lower respiratory tract infection through the RSV season. This analysis aims to evaluate nirsevimab's efficacy at 180 days after dosing, a period exceeding

BACKGROUND Risk stratification tools for paediatric community-acquired pneumonia (CAP) in well-resourced settings are scarce. We prospectively developed models to predict CAP severity within a multinational cohort of paediatric emergency departments (EDs). Our primary objective was to develop a risk prediction model to discriminate between mild CAP and moderate or severe CAP to assist clinicians in

Advances in paediatric haematopoietic cell transplantation strategies using immune-effector cells (HCT-IEC) and in intensive care management have improved survival expectations for patients with malignant and non-malignant diseases. However, critical illness still complicates the clinical course for 10-35% of patients undergoing HCT-IEC because of disease-related complications or treatment-related

BACKGROUND People with cystic fibrosis can have impaired insulin secretion and hyperglycaemia before meeting the diagnostic criteria for cystic fibrosis-related diabetes during an oral glucose tolerance test (OGTT). Insulin therapy given to such patients was associated with improved weight and lung function in several small, uncontrolled trials but might increase treatment burden and cause hypoglycaemia

Nirsevimab was approved in 2023, and implemented in all-infant immunisation programmes in several high-income countries to prevent lower respiratory tract infection (LRTI) caused by respiratory syncytial virus (RSV). Knowledge of real-world effectiveness of broad nirsevimab programmes is crucial to validate the benefits observed in clinical trials and guide immunisation policy. We assessed the real-world

Co-design methodologies are increasingly being used to develop mental health interventions with young people (aged 10–24 years), but the adoption of this participatory approach has been accompanied by concerns around quality, reporting, and participation. We aimed to identify and critically assess the characteristics, quality, outcomes, barriers, and facilitators of co-design methodologies used to

Pulmonary haemorrhage is a potentially life-threatening condition with a variety of causes. Quality clinical trials are insufficient in children, restricting the evidence base to observational data and adult studies. The overall management strategy should address control of symptomatic bleeding, identification of the bleeding source, and treatment of the underlying cause. Flexible bronchoscopy is an

Monogenic defects in the leptin-melanocortin pathway are associated with hyperphagia and severe, early-onset obesity. Early childhood growth patterns in height, weight, and BMI, might serve as phenotypic markers for specific genetic disorders; however, reliable data are scarce. This study aimed to evaluate the natural history of height, weight, and BMI in early childhood in a large European group of

Many treatments for abdominal pain-related disorders of gut–brain interaction (AP-DGBI) in children have been studied. We aimed to assess the efficacy and safety of all known treatment options for paediatric AP-DGBI.

Despite progress in reducing neonatal and child mortality, access to age-appropriate medicines remains inequitable, particularly in low-income and middle-income countries. The Global Accelerator for Paediatric Formulations (GAP-f), a WHO-hosted network established in 2020, addresses these gaps by uniting 33 partners to promote innovation and access to child-friendly formulations. Phase 2 (2022–24)

Respiratory syncytial virus (RSV) is a particularly dangerous infection in some populations, including very young infants. This study examined the efficacy and safety of ziresovir in hospitalised infants aged 6 months or younger with RSV infection.

The first dose of measles–rubella (MR) vaccine is routinely administered to infants aged 9 months as part of a standard two-dose schedule. However, during large measles outbreaks and in other settings of increased circulation or increased risk, WHO recommends administering a supplementary dose at age 6 months to protect young infants. We aimed to assess the immunogenicity and safety of a first dose

Pneumococcal meningitis is a leading cause of bacterial meningitis and the most deadly pneumococcal disease in children worldwide. There is a paucity of evidence concerning the benefit of dexamethasone to prevent death in paediatric pneumococcal meningitis. We aimed to compare the effect of early adjunctive therapy with dexamethasone versus no dexamethasone on death in children with pneumococcal meningitis

Skin conditions most frequently encountered in paediatric practice include infections, infestations, atopic dermatitis, and acne. Skin of colour refers to skin with increased melanin and darker pigmentation, and reflects global racial and ethnic diversity. Managing skin conditions in skin of colour requires health equity nuance, which is rarely explicitly taught. Awareness of the demographic factors

Generally, dose recommendations for children are expressed as fixed dosing increments related to bodyweight, known as weight bands. The weight bands recommended in WHO treatment guidelines vary between diseases, leading to complexity and potential dosing errors when treating children for multiple diseases simultaneously. The introduction of a harmonised weight banding approach for orally administered

Direct-acting antiviral treatment is associated with high rates of sustained virological response and has a favourable safety profile in children aged 3–17 years with chronic hepatitis C virus (HCV) infection, but data describing the durability of sustained virological response and its effects on growth and sexual development are needed. This study aimed to assess the efficacy and long-term effects

Pooled analyses summarising long-term growth outcomes in children who are HIV-exposed uninfected (HEU) compared with children who are HIV-unexposed (HU) are lacking. We aimed to summarise the existing literature on growth outcomes.

Research suggests gender inequalities in adolescent mental health are context dependent and might be preventable through social and structural change. However, variations in the size of gender inequalities in mental health across diverse cultural contexts could be due to incomparable measurement. We aimed to compare a measurement of mental health among young people in Tokyo, Japan, and London, UK,

BACKGROUND Lung function during childhood is an important predictor of subsequent health and disease. Understanding patterns of lung function and development of airflow limitation through childhood is necessary to inform lung function trajectories in relation to health and chronic airway disease. We aimed to derive trajectories of airflow limitation from childhood (age 5-8 years) into early adulthood

BACKGROUND Understanding the effects of SARS-CoV-2 infection and COVID-19 vaccination during pregnancy can help inform clinical guidance and tackle vaccine hesitancy. We examined relationships between SARS-CoV-2 infection during pregnancy, COVID-19 vaccination during pregnancy, and early child developmental concerns in children aged 13-15 months in Scotland. METHODS We created a large, population-level

High consequence infectious diseases (such as Ebola virus or avian influenza) require specialist management with strict isolation to avoid spread to health-care staff and the wider community. These infections present various ethical and legal issues for children and young people. Specific challenges include the impact of isolation on the child and family (potentially without a child's consent), limitations
