Delayed airway epithelial repair is correlated with airway obstruction in young adults born very pretermNasal epithelial cells from young adults with a history of very preterm birth show delayed closure following scratch-wounding. Repair correlated with lung function, suggesting epithelial barrier integrity may play a role in preterm-associated lung disease.

Global Lung Function Initiative reference values for multiple breath washout indicesMultiple 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.

Early nasal microbiota and subsequent respiratory tract infections in infants with cystic fibrosisRespiratory tract infections (RTIs) drive lung function decline in children with cystic fibrosis (CF). While the respiratory microbiota is clearly associated with RTI pathogenesis in infants without CF, data on infants with CF is scarce. We compared nasal microbiota development between infants with CF and controls and assessed associations between early-life nasal microbiota, RTIs, and antibiotic treatment in infants with CF.

MetaNeb Versus Usual Care During Exacerbations of Cystic Fibrosis: An RCTDuring exacerbations, when symptom and treatment burden are increased, individuals with cystic fibrosis (CF) are likely to prefer airway clearance techniques (ACTs) that require minimal effort. Therefore, in adults with CF who were hospitalised with an exacerbation, we sought to compare the effect of the MetaNeb with usual ACTs on respiratory function and expectorated sputum.
