Filter by:This non-interventional study is to analyse the therapeutic effectiveness in patients with severe COPD following a generally accepted 12-week treatment period with Symbicort Turbuhaler, which could anyhow be shortened or extended at physician's discretion.
Controlling the way people with lung problems breathe during arm exercises may reduce their breathlessness during activities of daily living that require them to lift their arms (i.e. brushing their hair, putting groceries away on high shelves). The main aim of this study is to determine the effects of specific breathing strategies during arm exercise on dyspnoea in patients with chronic lung disease. Coordinating inspiration with the action of arm elevation will reduce dyspnoea during a rhythmic overhead arm activity
Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the United States. Unlike the other leading causes of death, no medical therapies currently available improve the course of disease or affect survival in COPD. Recent investigations suggest that endothelial dysfunction and chronic inflammation is fundamental to COPD. Fish oil intake improves endothelial dysfunction and lowers levels of inflammatory intermediaries which may be important in the development of COPD. The Chronic Obstructive Pulmonary Disease Fish Oil (COD-Fish) Pilot Trial will enroll 40-45 participants with COPD. These participants will be randomized to receive omega-3 polyunsaturated fatty acid supplementation (PUFA) or placebo (containing corn oil). All participants will perform a number of noninvasive tests (including flow-mediated dilation (FMD) and pulmonary function testing) at study entry as well as every two months for a total of six months. Thirty participants who agree to it will undergo a separate procedure to collect cells from inside a forearm vein for analysis to be compared to 30 controls. The main purpose of this trial is to examine the effect of PUFA on endothelial function as measured by change in FMD in patients with COPD. We hypothesize that in subjects with COPD, treatment with PUFA will increase FMD.
To demonstrate the efficacy of ROX AC1 (with respect to exercise capacity and quality of life) in patients with COPD.
Objective: To investigate the potential role of endothelial dysfunction as a pathogenic mechanism of cardiovascular events in COPD. Hypothesis: endothelial function is abnormal in patients with COPD, particularly during exacerbations of the disease. Design: prospective and controlled study performed in an university hospital. Population: we compare 4 groups of subjects, 44 patients with stable COPD, 35 patients with acute exacerbation of COPD, 10 smokers or former smokers with normal lung function and 10 never smokers matched by physical activity and BMI. Study variables: a) clinical variables: clinical information, physical examination, pulmonary function tests, ECG and sputum culture; b) Biological variables: number of Circulating Endothelial Progenitor Cells, vascular growth factors (vascular endothelial growht factor and erythropoietin), systemic inflammation (C-reactive protein, white blood cells), peripheral venous blood test (including hemogram, biochemical analysis with glycemia, cholesterol, LDLcol, HDLcol); and c) systemic vascular reactivity assessment.
Infants less than 2 years old who have been newly diagnosed with problems swallowing will have pulmonary function tests performed to try to detect the presence of chronic lung disease. Six months later after the infants have received appropriate therapy for their swallowing problems, pulmonary function tests will be performed again to see if there has been any change in their chronic lung disease.
Bone-marrow-derived progenitor cells (EPCS) play an important role in neovascularization and tumor growth. In lung cancer, angiogenesis is an important event in mechanisms of tumor proliferation and metastasis. Recent evidences suggest that EPCS can be recruited and differentiate in mature endothelial cells to form new blood vessels. The role of EPCs in NSCLC is unclear. In contrast, angiogenic drugs are proposed combined to systemic chemotherapy in NSCLC. The aim of this study is to identify EPCs in peripheral blood from patients with NSCLC, by comparison to Chronic Pulmonary Obstructive Disease (COPD), an inflammatory disease.
We hypothesize that ongoing and more severe airway inflammation in COPD may result from the impairment in activation of innate immune response
Recent guidelines on pulmonary rehabilitation (PR) recommend upper extremity exercise training (UEET) in patients with chronic obstructive pulmonary disease (COPD). The theory supporting the inclusion of upper extremity exercise training in the pulmonary rehabilitation for these patients, is based on the profound understanding of the activity of the accessory respiratory muscles, which are competitively involved in both the support of the upper extremities during activities and the ventilation. However, a systematic review of the literature carried out by our staff reveals that the clinical trials carried out up to now to verify the effectiveness of UEET are of poor methodological quality and the investigators cannot corroborate the recommendation recently made on the basis of the results of the investigators' review. Therefore the investigators began this randomized, parallel groups, controlled clinical trial with the purpose of determining the short-term effect of unsupported UEET on the performance of the upper extremities and on symptoms perceived during activities by patients with COPD.
The purpose of the study is to assess the safety and the effect of treatment by PulseHaler™ on patients with COPD, as measured by the change from baseline in full pulmonary functions, oxygen saturation, exercise tolerance and health related quality of life; and to assess the ease of use of PulseHaler™ by the patients.
