Chronic, low-intensity air pollution exposure has been consistently associated with reduced lung function throughout childhood. However, there is limited research regarding the implications of acute, high-intensity air pollution exposure. We aimed to determine whether there were any associations between early life exposure to such an episode and lung growth trajectories.
Obstructive sleep apnea (OSA) increases the risk of perioperative adverse events in children. While polysomnography (PSG) remains the reference standard for OSA diagnosis, oximetry is a valuable screening tool. The traditional practice is the manual analysis of desaturation clusters derived from a tabletop device using the McGill oximetry score. However, automated analysis of wearable oximetry data can be an alternative. This study investigated the accuracy of wrist-worn oximetry with automated analysis as a preoperative OSA screening tool.
The long-term cardiopulmonary outcomes following preterm birth during the surfactant era remain unclear. Respiratory symptoms, particularly exertional symptoms, are common in preterm children. Therefore, cardiopulmonary exercise testing may provide insights into the pathophysiology driving exertional respiratory symptoms in those born preterm. This review aims to outline the current knowledge of cardiopulmonary exercise testing in the assessment of children born preterm in the surfactant era.
This document updates the 2005 European Respiratory Society (ERS) and American Thoracic Society (ATS) technical standard for the measurement of lung volumes. The 2005 document integrated the recommendations of an ATS/ERS task force with those from an earlier National Heart, Lung, and Blood Institute workshop that led to the publication of background papers between 1995 and 1999 and a consensus workshop report with more in-depth descriptions and discussion.

Preterm birth is associated with increased mortality and morbidity, particularly due to lung disease. Low- and middle-income countries (LMIC) have the highest rates of preterm birth. Infants born extremely preterm rarely survive, so the largest burden is amongst moderate-to-late preterm (MLP) infants. The long-term health impact on MLP children in LMIC is poorly understood. The aim of this study was to assess the effect of MLP birth on lung function trajectories from birth to 5 years in the Drakenstein Child Health Study.
Lung function testing and lung imaging are commonly used techniques to monitor respiratory diseases, such as cystic fibrosis (CF). The nitrogen (N2) multiple-breath washout technique (MBW) has been shown to detect ventilation inhomogeneity in CF, but the underlying pathophysiological processes that are altered are often unclear.
The airway epithelium is the primary structural and functional airway barrier and orchestrates innate immunity. Some children may have underlying epithelial vulnerabilities that contribute to the pathogenesis of acute wheeze and asthma.
Few studies exist investigating lung function trajectories of those born preterm; however growing evidence suggests some individuals experience increasing airway obstruction throughout life. Here we use the studies identified in a recent systematic review to provide the first meta-analysis investigating the impact of preterm birth on airway obstruction measured by the forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) ratio.
Arsenic is the only environmental toxin that has been linked to both malignant and nonmalignant respiratory disease following ingestion, rather than inhalation, making arsenic a unique toxicant to the respiratory system. Chronic exposure to arsenic has been associated with the development of respiratory symptoms, impaired lung function, and chronic lung disease.
