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.

The clinical utility of lung clearance index in early cystic fibrosis lung disease is not impacted by the number of multiple-breath washout trialsThis study aimed to determine if relationships between LCI and clinical outcomes of CF lung disease differ when only two acceptable MBW trials are assessed.

Mannitol challenge testing for asthma in a community cohort of young adultsWe aimed to quantify the diagnostic utility of mannitol challenge testing for asthma in a community cohort and a symptomatic wheezing subset of this cohort.

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.

FINGERPRINT: FINdinG Early markers of Respiratory disease for survivors of PReterm birth which IdeNtify Treatable traitsThis research project will investigate the traits of preterm lung disease, looking into the long-term lung health of children born preterm, aiming to identify traits that could help guide better treatments in the future.

The Impact of Modulator therapy from Early life on lung health trajectories in Cystic Fibrosis (TIME-CF)Cystic fibrosis is an inherited condition that results in chronic lung disease. In recent years, a new type of medication called CFTR modulators has become available.

Long-term medical and psychosocial outcomes in congenital diaphragmatic hernia survivorsSurvivors of CDH may have significant adverse long-term medical and psychosocial issues that would be better recognised and managed in a multidisciplinary clinic

Lung inflammation and simulated airway resistance in infants with cystic fibrosisCystic fibrosis (CF) is characterized by small airway disease; but central airways may also be affected. We hypothesized that airway resistance estimated from computational fluid dynamic (CFD) methodology in infants with CF was higher than controls and that early airway inflammation in infants with CF is associated with airway resistance.
