Objectives: To examine the association among acute bronchiolitis-related hospitalisation in children, meteorological variation and outdoor air pollution.
Methods: We obtained the daily counts of acute bronchiolitis-related admission of children≤2 years old from all public hospitals, meteorological data and outdoor air pollutants' concentrations between 1 January 2008 and 31 December 2017 in Hong Kong. We used quasi-Poisson generalised additive models together with distributed lag non-linear models to estimate the associations of interest adjusted for confounders.
Results: A total of 29 688 admissions were included in the analysis. Increased adjusted relative risk (ARR) of acute bronchiolitis-related hospitalisation was associated with high temperature (ambient temperature and apparent temperature) and was marginally associated with high vapour pressure, a proxy for absolute humidity. High concentration of NO was associated with elevated risk of acute bronchiolitis admission; the risk of bronchiolitis hospitalisation increased statistically significantly with cumulative NO exposure over the range 66.2-119.6 µg/m. For PM, the significant effect observed at high concentrations appears to be immediate but not long lasting. For SO, ARR increased as the concentration approached the 75th percentile and then decreased though the association was insignificant.
Conclusions: Acute bronchiolitis-related hospitalisation among children was associated with temperature and exposure to NO and PM at different lag times, suggesting a need to adopt sustainable clean air policies, especially to target pollutants produced by motor vehicles, to protect young children's health.

Nirsevimab and Acute Bronchiolitis Episodes in Pediatric Emergency Departments.

Article Synopsis
- - Spain introduced universal RSV prophylaxis in the 2023-2024 season, allowing all newborns to receive nirsevimab, particularly benefiting infants under 6 months through extended immunization efforts.
- - A study in 15 pediatric emergency departments showed significant decreases in respiratory infections: a 57.7% drop in lower respiratory tract infections and a 63.1% reduction in hospital and PICU admissions related to acute bronchiolitis.
- - The findings indicate that nirsevimab is highly effective in protecting infants from RSV, with extended catch-up immunization yielding the best results, although cost-effectiveness remains a consideration.

Pediatrics, among all the branches of medicine, is a sector not particularly affected by a high number of claims. Nevertheless, the economic value of the compensation is significantly high, for example, in cases of children who suffered multiple disabilities following perinatal lesions with a long life expectancy. In Italy, most of the claims for compensation concern surgical pathologies and infections.

Rational: This study aims to describe the current weaning practices from any type of noninvasive support in infants with bronchiolitis, in terms of weaning procedures, weaning initiation and weaning failure criteria.
Working Hypothesis: No information regarding the weaning practices is currently available and there may be a wide variability of strategies.
Study Design: A cross-sectional electronic survey.

Introduction: Respiratory syncytial virus (RSV) is the leading viral cause of acute lower respiratory infections globally, accounting for high morbidity and mortality burden among children aged less than 5 years. As candidate RSV vaccine trials in pregnant women and infants are underway a greater understanding of RSV epidemiology is now needed, especially in paediatric populations with high rates of acute and chronic respiratory disease. The objective was to identify RSV prevalence in children living in northern Australia, a region with a high respiratory disease burden.
