Associations between respiratory and vascular function in early childhoodThe link between respiratory and vascular health is well documented in adult populations. Impaired lung function is consistently associated with thicker arteries and higher incidence of cardiovascular disease. However, there are limited data on this relationship in young children and the studies that exist have focussed on populations at high risk of cardiorespiratory morbidity.

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

Comparing home polysomnography with transcutaneous CO2 monitoring to laboratory polysomnography in children with neuromuscular disordersClinical utility of home polysomnography in children with neuromuscular disorders is limited by lack of evidence that sleep-disordered breathing can be reliably identified and inability to diagnose hypoventilation because carbon dioxide is not measured.

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.

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.

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.
