Mucus plays an integral role for the barrier function of many epithelial tissues. In the human airways, mucus is constantly secreted to capture inhaled microbes and pollutants and cleared away through concerted ciliary motion. Many important respiratory diseases exhibit altered mucus flowability and impaired clearance, contributing to respiratory distress and increased risk of infections.

Objective: Cystic fibrosis (CF) is a clinical entity defined by aberrant chloride (Cl) ion transport causing downstream effects on mucociliary clearance (MCC) in sinonasal epithelia. Inducible deficiencies in transepithelial Cl transport via CF transmembrane conductance regulator (CFTR) has been theorized to be a driving process in recalcitrant chronic rhinosinusitis (CRS) in patients without CF. We have previously identified that brief exposures to bacterial lipopolysaccharide (LPS) in mammalian cells induces an acquired dysfunction of CFTR in vitro and in vivo.

Less is known about the extrapulmonary impact of ETI and effects on airway microbiology, lung clearance index (LCI) and fraction of exhaled nitric oxide (FeNO).
Methods: A multicentre prospective observational trial, including 79 pwCF ≥ 18 years eligible for ETI.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, characterized by chronic mucus hypersecretion (CMH) that exacerbates airway obstruction and accelerates disease progression. Effective airway clearance techniques are essential to improve respiratory function and reduce exacerbations. Temporary Positive Expiratory Pressure (T-PEP) is a novel airway clearance device that has shown promise in managing COPD.

Introduction: Acute exacerbations of COPD (AECOPD) often involve mucus hypersecretion. Thus, management of sputum retention is critical. However, the use of airway clearance techniques (ACTs) in people with AECOPD across different healthcare settings and factors influencing their selection remain unclear.
