Impact of HIV and antiretroviral drug exposure on lung growth and function over 2 years in an African Birth CohortHIV exposure is associated with altered lung function in early life, with a vulnerable HIV-exposed uninfected subgroup based on maternal disease severity

Multi-ancestry genome-wide association analyses improve resolution of genes and pathways influencing lung function and chronic obstructive pulmonary disease riskLung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups.

Ventilatory response and stability of oxygen saturation during a hypoxic challenge in very preterm infantsPreterm infants have immature control of breathing and impaired pulmonary gas exchange. We hypothesized that infants with bronchopulmonary dysplasia (BPD) have a blunted ventilatory response and peripheral oxygen saturation (SpO2 ) instability during a hypoxic challenge.

Health service utilisation for acute respiratory infections in infants graduating from the neonatal intensive care unit: a population-based cohort studyDespite advances in neonatal intensive care, babies admitted to Neonatal Intensive Care Units (NICU) suffer from adverse outcomes. We aim to describe the longer-term respiratory infectious morbidity of infants discharged from NICU using state-wide population-based linked data in Western Australia.

Which reference equation should we use for interpreting spirometry values for First Nations Australians? A cross-sectional studyTo evaluate the suitability of the Global Lung Function Initiative (GLI)-2012 other/mixed and GLI-2022 global reference equations for evaluating the respiratory capacity of First Nations Australians.

Determinants of lung function development from birth to age 5 years: an interrupted time series analysis of a South African birth cohortEarly life is a key period that determines long-term health. Lung development in childhood predicts lung function attained in adulthood and morbidity and mortality across the life course. We aimed to assess the effect of early-life lower respiratory tract infection (LRTI) and associated risk factors on lung development from birth to school age in a South African birth cohort.

Signal-correction errors in the EasyOne Pro LAB multiple-breath washout device significantly impact outcomes in children and adultsMultiple-breath washout (MBW) is an established technique to assess functional residual capacity (FRC) and ventilation inhomogeneity in the lung. Indirect calculation of nitrogen concentration requires accurate measurement of gas concentrations.

ERS technical standard on bronchial challenge testing: pathophysiology and methodology of indirect airway challenge testingAssessment of airway hyperresponsiveness are valuable tools to understand and to monitor airway function and to characterise the underlying asthma phenotype to guide therapy

A novel, palatable paediatric oral formulation of midazolam: Pharmacokinetics, tolerability, efficacy and safetyWe conclude that the novel chocolate-based formulation of midazolam provides improved tolerability while remaining efficacious

Single-breath washout and association with structural lung disease in children with cystic fibrosisAcinar ventilation inhomogeneity measured by single-breath washout was not associated with structural lung disease on CT
