Filter by:The purpose of this study is to determine whether or not vitamin D supplementation can improve physical performance in persons with severe chronic obstructive pulmonary disease (COPD).
The purpose of this study is to determine whether Written Disclosure Therapy (WDT) is of any benefit to patients with chronic lung diseases who are participating in pulmonary rehabilitation.
This is a multi-center study to evaluate the long-term safety of arformoterol 15 mcg twice daily (BID) in the treatment of subjects with moderate-to-severe COPD. Study participation will consist of a total of 6 visits over approximately 1 year.
Reduced exercise tolerance is one of the hallmarks of COPD. The principal causes for exercise intolerance are ventilatory limitation leading to deconditioning and inactivity. So far it is poorly understood which form of exercise is the most effective in training this condition. The investigators want to study the physiological response to two different training programs (High intensity aerobe interval training and moderate continuous aerobe training)with special focus on cardiac and skeletal muscle adaptions
Airway dendritic cells (DCs) play a key role in smoke-related lung diseases. In this study, the researchers investigate the effects of fluticasone and salmeterol on human airway DCs in smokers. The researchers hypothesize that fluticasone and salmeterol impact on the number and the characteristics of airway DCs in smokers.
The purpose of this research is to understand the properties of mucus in persons with COPD, specifically Chronic Bronchitis. We hypothesize that those with Chronic Bronchitis have dehydrated mucus, and thus have a harder time coughing it out of their lungs. This leads to a greater vulnerability for lung infection, inflammation and airflow obstruction. Ultimately, our goal is to understand how mucus dehydration contributes to the progression of COPD/Chronic Bronchitis so that better therapies and interventions can be developed for future generations.
This study compared the lung effects of indacaterol to those of tiotropium in patients with moderate to severe chronic obstructive pulmonary disease (COPD) over a 12 week period.
Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without. Previous studies have indicated that decreasing hemoglobin oxygen saturation during exercise may predict in-flight hypoxemia. The objective of the present study is to examine if adding exercise oxygen desaturation to the BTS algorithm will better predict requirements for in-flight supplementary oxygen.
The aim of this study is to assess the perception of chronic obstructive pulmonary disease (COPD) patients in symptoms related to morning activities. Also the researchers investigated how to describe the impact of symptoms on sleep quality and how to use the medication in Korea COPD treatments.
The purpose of this study is to assess the efficacy (effectiveness) and safety of aclidinium bromide doses as compared to placebo in the treatment of moderate to severe chronic obstructive pulmonary disease. The study will be 16 weeks in duration; 2-week run-in period, 12-week double-blind treatment, and 2-week follow-up phone visit.
