Background: Although the demand for allografts continuously surpasses the supply, the majority of lungs offered for transplant are declined based on various factors, including donor age. This in turn sustains the wait-list mortality of patients with end-stage pulmonary disease.
Methods: In this single-center, observational cohort study, we investigated the impact of donor age on graft survival.
Background: Methods used to assess ventilation heterogeneity through inert gas washout have been standardised and showed high sensitivity in diagnosing many respiratory diseases. We hypothesised that nitrogen single or multiple breath washout tests, respectively nitrogen single breath washout (NSBW) and nitrogen multiple breath washout (NMBW), may be pathological in patients with clinical suspicion of asthma but normal spirometry. Our aim was to assess whether NSBW and NMBW are associated with methacholine challenge test (MCT) results in this population.

Methods And Results: This retrospective analysis of the Swiss PH Registry included incident patients with CpcPH registered from January 2001 to June 2019 at 13 Swiss hospitals.

Background: Although inhaled corticosteroids (ICS) are highly effective in asthma, they provide significant, but modest, clinical benefit in COPD. Here, we tested the hypothesis that high bronchial airway smooth muscle cell (ASMC) area in COPD is associated with ICS responsiveness.
Methods: In this investigator-initiated and -driven, double-blind, randomised, placebo-controlled trial (HISTORIC), 190 COPD patients, Global Initiative for Chronic Obstructive Lung Disease stage B-D, underwent bronchoscopy with endobronchial biopsy.
Background: PCR-based testing has transformed the management of suspected respiratory viral infections. We aimed to determine whether multiplex bacterial PCR of bronchoalveolar lavage fluid aids antibiotic stewardship in patients with pneumonia.
Methods: This investigator-initiated, multicentre, randomised controlled trial was conducted at two tertiary care centres in Switzerland (University Hospital of Basel and Kantonsspital St Gallen).
Background: Obstructive sleep apnea (OSA) is characterized by repetitive episodes of complete or partial obstruction of the upper airways during sleep. Conscious sedation for flexible bronchoscopy (FB) places patients in a sleep-like condition. We hypothesize that oxygen desaturation during flexible bronchoscopy may help to detect undiagnosed sleep apnea.
