Journal ArticleDOI
Increased plasma endothelin-1 in pulmonary hypertension: marker or mediator of disease?
TL;DR: In patients with primary pulmonary hypertension, the high levels in arterial compared with venous plasma suggest pulmonary production of endothelin-1, which may contribute to elevated pulmonary vascular resistance.
Journal ArticleDOI
Effects of Home-Based Pulmonary Rehabilitation in Patients with Chronic Obstructive Pulmonary Disease: A Randomized Trial

TL;DR: Self-monitored, home-based pulmonary rehabilitation would be as effective as outpatient, hospital-based rehabilitation for improving dyspnea at 1 year, according to a parallel-group, randomized, noninferiority, multicenter clinical trial in Canada.
Journal ArticleDOI

TL;DR: Airway wall thickening and emphysema make independent contributions to airflow obstruction in COPD and these phenotypes show independent aggregation within families of individuals with COPD, suggesting that different genetic factors influence these disease processes.
Journal ArticleDOI
Ventilatory muscle support in respiratory failure with nasal positive pressure ventilation.
TL;DR: The results indicate that NPPV can noninvasively provide ventilatory support while reducing inspiratory muscle energy expenditure in acute and chronic respiratory failure of diverse etiology.
Journal ArticleDOI
Lung transplant outcomes: a review of survival, graft function, physiology, health-related quality of life and cost-effectiveness.
TL;DR: The success of lung transplantation has improved over time as evidenced by better long-term survival and functional outcomes, but significant improvement will only occur when better methods exist to prevent or effectively treat chronic rejection.
