Unstable SpO2 in preterm infants: The key role of reduced ventilation to perfusion ratio

Instability of peripheral oxyhemoglobin saturation (SpO2) in preterm infants is correlated with late disability and is poorly understood. We hypothesised that a reduced ventilation to perfusion ratio (VA/Q) is the key predisposing factor for SpO2 instability.

Characterisation of lung function trajectories and associated early-life predictors in an Australian birth cohort study

There 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.

Exhaled breath temperature in healthy children is influenced by room temperature and lung volume

Exhaled breath temperature (EBT) has been proposed for the non-invasive assessment of airway inflammation

Global Lung Function Initiative reference values for multiple breath washout indices

Multiple breath washout is a lung function test based on tidal breathing that assesses lung volume and ventilation distribution. The aim of this analysis was to use the Global Lung Function Initiative methodology to develop all-age reference equations for the multiple breath washout indices lung clearance index and functional residual capacity.

Lung study helps history-making generation get a handle on their health

A lung function study carried out by Dr Shannon Simpson provided the most comprehensive follow-up of very pre-term children of any study so far carried out on the lung health of this vulnerable group.

ERS/ATS technical standard on interpretive strategies for routine lung function tests

Appropriate interpretation of pulmonary function tests (PFTs) involves the classification of observed values as within/outside the normal range based on a reference population of healthy individuals, integrating knowledge of physiological determinants of test results into functional classifications and integrating patterns with other clinical data to estimate prognosis.

Variants associated with HHIP expression have sex-differential effects on lung function

Lung function is highly heritable and differs between the sexes throughout life. However, little is known about sex-differential genetic effects on lung function. We aimed to conduct the first genome-wide genotype-by-sex interaction study on lung function to identify genetic effects that differ between males and females.

Association between diesel engine exhaust exposure and lung function in Australian gold miners

Diesel engine exhaust exposures were higher in underground miners and had a negative association with their lung function over a single 12-h shift

Infection, inflammation,and lung function decline in infants with cystic fibrosis

Better understanding of evolution of lung function in infants with cystic fibrosis...

Wal-yan Centre scholarship awardees to research interventions for improving lung health

As part of the Wal-yan Respiratory Research Centre’s aim to support the next generation of scientists in children’s respiratory research, a competitive scholarship program was introduced this year.
