Filter by:Comparison of humidification devices during non invasive ventilation, in acute respiratory failure. The hypothesis was, due to dead space, lower humidification, a reduced efficiency of the technique (NIV) when HME are used in comparison with HH.
The study will evaluate the efficacy and safety of basiliximab Vs placebo as induction therapy combined with standard triple immunosuppression therapy, in the prevention of acute rejection episodes and prevention of Bronchiolitis Obliterans Syndrome.
A breathing condition known as "chronic obstructive pulmonary disease" (COPD) caused by cigarette smoking is a major health problem. The way by which smoking leads to lung disease is uncertain. Recent research done in animals provides a description of specific changes (that is a reduction) in these immune cell types as a result of cigarette smoke exposure. The study you have been asked to participate in is a pilot study to see if similar changes occur in humans who smoke. The purpose of this study is to evaluate this new method of testing blood in 3 groups of 10 people: normal non-smoking subjects, subjects who smoke with no history of lung disease and subjects who smoke and have smoking related COPD.
Does an oral selenium supplement increase blood levels of antioxidants in patients with established, smoking-related lung disease? Members of our study group recently discovered that elevated levels of the anti-oxidant GPx-1 may be protective against heart disease. We are studying whether selenium supplementation will improve GPx-1 levels.
The objective of this study was to evaluate the use of high frequency chest wall oscillation (HFCWO) early in the treatment of adults hospitalized for acute asthma or chronic obstructive pulmonary disease (COPD).
The purpose of this study is to determine whether macrolide therapy is effective in treating patients hospitalized with asthma exacerbations or chronic obstructive pulmonary disease (COPD)exacerbations. We hypothesize that compared to placebo, maintenance therapy with macrolides, when added to usual care, a) improves respiratory symptoms, b) improves quality of life, c) reduces airway inflammation, d) reduces airflow obstruction, and e) decreases the rate of re-exacerbations.
The purpose of this study is to show that one form of mechanical airway clearance techniques, High Frequency Chest Wall Oscillation (HFCWO)using a pneumatic vest, will diminish exacerbations of COPD which will improve respiratory health status.
Subjects undergo history, examination, lung function assessment after informed consent has been obtained. All subjects will undergo ventilation-perfusion scans. If there first scan is normal they will undergo a second and final scan four weeks later. If abnormal they will undergo two further scans with either nebulized bronchodilator or nebulized saline prior to their second and third scans. Each time they will have repeat lung function tests prior to scanning. We will examine the regional changes in ventilation and perfusion and there relationship to lung function.
We wish to study the effect of Chronic Obstructive Pulmonary Disease on the activity of the nuclear transcription pathway in peripheral skeletal muscle to determine whether altered activity of this pathway may be responsible for the muscle dysfunction observed in these patients.
The primary aim of this study is to investigate the effects of oral and inhaled administration of L-arginine and of inhaled aminoguanidine on bronchial and alveolar exhaled NO and NO metabolites in exhaled breath condensate, induced sputum, nasal lavage and mouth wash fluid in healthy non-smokers, current smokers and patients with COPD.
