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.

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.

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.

Lung volumes, gas transfer and oscillometry after preterm birth: systematic review and meta-analysisSmall airway and lung parenchymal abnormalities frequently occur following preterm birth but are commonly missed by spirometry. Static lung volumes, diffusing capacity of the lung for carbon monoxide (D LCO) and oscillometry provide a more precise characterisation of these conditions. We hypothesised that differences in these measures exist between individuals born preterm and at term and we aimed to systematically review the literature to identify and quantify these differences in lung function.

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.

Exhaled breath temperature in healthy children is influenced by room temperature and lung volumeExhaled breath temperature (EBT) has been proposed for the non-invasive assessment of airway inflammation

Changes in lung volume during spells in children with Tetralogy of Fallot under general anesthesiaTo describe the changes in end-expiratory lung volume and ventilation inhomogeneities during spells in three children with Tetralogy of Fallot.

Lung function testing in preschool-aged children with cystic fibrosis in the clinical settingThis study investigated the nature and prevalence of atypical pain responses in Rett syndrome and their relationships with specific MECP2 mutations.

Consensus statement for inert gas washout measurement using multiple- and single- breath testsInert gas washout tests, performed using the single- or multiple-breath washout technique, were first described over 60 years ago.
