Age- and height-based prediction bias in spirometry reference equationsPrediction bias in spirometry reference equations can arise from combining equations for different age groups,...

Air travel and the risks of hypoxia in childrenIn infants and children with chronic respiratory disease, hypoxia is a potential risk of aircraft travel.

The all-age spirometry reference ranges reflect contemporary Australasian spirometryAdvances in statistical modelling have allowed the creation of smoothly changing spirometry reference ranges that apply across a wide age range and better...

Influence of secular trends and sample size on reference equations for lung function testsThe aim of our study was to determine the contribution of secular trends and sample size to lung function reference equations, and establish the number...

Transcriptomic analysis of primary nasal epithelial cells reveals altered interferon signalling in preterm birth survivors at one year of ageMany survivors of preterm birth (<37 weeks gestation) have lifelong respiratory deficits, the drivers of which remain unknown. Influencers of pathophysiological outcomes are often detectable at the gene level and pinpointing these differences can help guide targeted research and interventions. This study provides the first transcriptomic analysis of primary nasal airway epithelial cells in survivors of preterm birth at approximately 1 year of age.

The ventilatory response to hypoxia is blunted in some preterm infants during the second year of lifePreterm birth and subsequent neonatal ventilatory treatment disrupts development of the hypoxic ventilatory response (HVR). An attenuated HVR has been identified in preterm neonates, however it is unknown whether the attenuation persists into the second year of life.

Characterisation of lung function trajectories and associated early-life predictors in an Australian birth cohort studyThere is growing evidence that lung function in early-life predicts later lung function. Adverse events over the lifespan might influence an individual’s lung function trajectory, resulting in poor respiratory health. The aim of this study is to identify early-life risk factors and their impact on lung function trajectories to prevent long-term lung impairments.

Inhaled corticosteroids to improve lung function in children (aged 6–12 years) who were born very preterm (PICSI): a randomised, double-blind, placebo-controlled trialDespite the substantial burden of lung disease throughout childhood in children who were born very preterm, there are no evidence-based interventions to improve lung health beyond the neonatal period. We tested the hypothesis that inhaled corticosteroid improves lung function in this population.

Daytime sleepiness and emotional and behavioral disturbances in Prader-Willi syndromeIndividuals with Prader-Willi syndrome (PWS) often have excessive daytime sleepiness and emotional/behavioral disturbances. The objective of this study was to examine whether daytime sleepiness was associated with these emotional/behavioral problems, independent of nighttime sleep-disordered breathing, or the duration of sleep.
