Filter by:This is a randomized, double-blind, multi-dose, parallel group trial which will assess the pharmacodynamic response of fluticasone propionate and formoterol fumarate in subjects with COPD.
This study was designed to test the following hypothesis: To investigate whether COPD muscles can respond to stimuli in terms of changes in fiber-type distribution.
This project will examine the current diagnosis and treatment of bone health in patients with obstructive airway disease. Patients will be referred to The Osteoporosis Centre of BC (OCBC) by their respirologist to be assessed for osteoporosis including Dual Energy Xray Absorptiometry (DXA) scan. Previous chest xrays and will be accessed and examined for vertebral fractures, diagnostic of osteoporosis. The lung and bone data will be entered into a database. This will allow us to explore the relationship of lung disease parameters to osteoporosis predictors, eventually determining a respirology patient population who are at high risk of fracture. Longitudinal evaluation of bone health and its relationship to respiratory parameters over time will be explored by follow-up evaluations at 12 and 24 months.
HYPOTHESIS:The study purpose is to evaluate the effectiveness of a structured pursed-lips breathing (PLB) protocol taught via real-time interactive telecommunication with a home computer using the lnternet and Skype software in veterans with chronic obstructive pulmonary disease (COPD. The primary hypothesis is veterans with COPD and dyspnea on exertion who receive a PLB educational intervention taught via weekly interactive telecommunication over a 4-week period will have greater reduction of exertional dyspnea compared to those who receive the PLB educational intervention with no weekly interactive sessions. RESEARCH PLAN: An experimental two- group design is used. All subjects receive a brief 5 - 10 minute one-on-one PLB educational session. Subjects are then randomized to either the intervention group or the control group. The intervention group receives 4 weekly interactive group sessions with the health educator (principal investigator)via computer. A free software program known as Skype allows synchronous video and audio interaction. The comparison group receives only the brief PLB educational session with no weekly follow-up. RESULTS: At end of 4 weeks, the intervention group had significantly lower dyspnea intensity scores (group X time interaction F = 6.69, p = 0.02) and significantly higher social support scores (group x time interaction F = 4.34, p = 0.058). CLINICAL SIGNIFICANCE: Skype is a viable means for providing patient education. A structured PLB protocol provides significant differences in exertional dyspnea over time. A structured PLB protocol plus Skype showed significant reduction in patients' sense of dyspnea intensity and increased social support scores.
The aim of this study is the first aim of a NIH project that consists of 3 aims. The first aim examines the acute effects of two high-quality milk proteins (casein vs. whey) on whole-body and muscle protein metabolism in COPD patients with severe loss of muscle mass and the effects of adding leucine. The principal endpoints will be the extent of stimulation of net whole body protein synthesis as this is the principal mechanism by which either amino acid or protein intake causes muscle anabolism. After determining the optimal nutritional formulation based on the first aim we will continue to work on the second and third aim where fish oil supplementation will be part of the nutritional intervention as well.
The ability for patients with COPD to exercise is limited due to the deterioration of their lung function. NVA237 is being developed to treat COPD. This study is designed to look at how well NVA237 improves the ability to exercise in patients with moderate to severe COPD.
The purpose of the study is to find out if AZD2423 can reduce inflammation in the lungs of patients with mild COPD.
To validate the capability of the Respironics Synchrony ventilator to properly detect Expiratory Flow Limitation (EFL) as compared to the gold standard method of detecting EFL via the Mead and Wittenberger technique.
Chronic obstructive pulmonary disease (COPD) is a condition of the lungs which results in breathing difficulties due to the lungs becoming inflamed and the airways narrowed. Current treatments have focused on opening up the narrowed airways but, in addition, we know there is increased inflammation in the blood and these patients are at increased risk of heart disease. Statins, simvastatin being one of them, are drugs used to lower cholesterol in the blood but may also reduce inflammation and lower the risk of heart disease. This study will explore whether simvastatin reduces one of the risk factors in patients with COPD in a short term proof of principle study. The key purpose is to determine whether simvastatin improves the pressure and stiffness of the main blood vessels namely the arterial stiffness measure of aortic pulse wave velocity (PWV). In parallel, we will describe changes in airways and / or blood inflammation and change in breathing ability
Chronic obstructive pulmonary disease (COPD) is number four of the leading causes of death in the USA and Europe. Moreover, among the top five causes of death, this disease is the only one with increasing mortality rates. Physical training has become an evidence based therapeutic intervention in these patients. In this study the investigators aim to establish if supplemental oxygen during strength and endurance training improves exercise tolerance. Furthermore, the investigators want to research, if supplemental oxygen has the ability to increase training intensity, which would lead to a greater training effect with respect to respiratory, vascular, inflammatory and anthropometric parameters, as well as quality of life. SCOPE is a prospective, randomized, double-blinded, controlled, cross-over trial. The investigators aim to enroll 40 patients suffering from COPD aged >30 years. Inclusion criteria are FEV1 30-60%, and PO2 at rest >55 mmHg. At baseline, patients will undergo pre-tests including pulmonary, exercise physiological and medical investigations. Prior to the exercise training, an intervention-free control period with usual care is planned. This will be followed by 2 x 6 weeks with physical training (ergometer based endurance training and strength training, using weight lifting machines) with either supplemental oxygen or usual room air (e.g.: first 6 weeks of exercise with oxygen supplementation followed by 6 weeks of room air). After the initial control period and between these two exercise periods, patients will be tested as described in pre-tests, and at the end of the second exercise training period. In addition, the investigators will assess changes in lung function and symptomatic dyspnoea, as well as in quality of life (St. George's Respiratory Questionnaire). Within this study, the investigators hope to improve rehabilitation programs for COPD patients.
