Non-invasive positive pressure ventilation for the treatment of severe stable chronic obstructive pulmonary disease: a prospective, multicentre, randomised, controlled clinical trial

TL;DR: The assessment of chronic obstructive pulmonary disease has been refined to separate the spirometric assessment from symptom evaluation, and the concept of deescalation of therapy is introduced in the treatment assessment scheme.

TL;DR: The assessment of chronic obstructive pulmonary disease has been refined to separate the spirometric assessment from symptom evaluation, and the concept of de‐escalation of therapy is introduced in the treatment assessment scheme.

TL;DR: The assessment of COPD has been refined to separate the spirometric assessment from symptom evaluation, and the concept of de-escalation of therapy is introduced in the treatment assessment scheme.

TL;DR: The assessment of chronic obstructive pulmonary disease has been refined to separate the spirometric assessment from symptom evaluation, and the importance of comorbid conditions in managing COPD is reviewed.

TL;DR: The St. George's Respiratory Questionnaire is a valid measure of impaired health in diseases of chronic airflow limitation that is repeatable and sensitive andMultivariate analysis demonstrated that SGRQ scores summed a number of areas of disease activity.

TL;DR: The St George's Respiratory Questionnaire is a standardized self-completed questionnaire for measuring impaired health and perceived well-being in airways disease and the background and rationale for its development are discussed together with an analysis of its performance.

TL;DR: This research presents a novel and scalable approach called “Standardation of LUNG FUNCTION TESTing” that combines “situational awareness” and “machine learning” to solve the challenge of integrating nanofiltration into the energy system.

TL;DR: There has been a nearly exponential increase in the use of quality-of-life evaluation as a technique of clinical research since 1973, when only 5 articles listed “quality of life” as a reference key word in the MEDLINE data base; during the subsequent five-year periods there were 195, 273, 490, and 1252 such articles.
