Filter by:The purpose of this study is to determine whether telehealth nursing consultations of chronic obstructive pulmonary disease (COPD) patients are superior to hospital readmissions.
Conventional pulmonary rehabilitation programs improve exercise tolerance, peripheral muscle strength, and health related quality of live but not pulmonary function in patients with chronic obstructive pulmonary disease (COPD). The role of breathing retraining techniques in the rehabilitation of patients with COPD remains unclear. The hypothesis to be tested in this study is that pulmonary function, cardio-pulmonary exercise capacity, health related quality of life and cardiac autonomic modulation of patients with COPD who undergo pulmonary rehabilitation plus breathing retraining will be better than that of patients undergoing a conventional pulmonary rehabilitation.
Pursed-lip breathing (PLB) has been advocated to reduce respiratory rate and improve oxygen saturation in patients with chronic obstructive pulmonary disease (COPD) at rest. Although PLB is a strategy that potentially reduces expiratory flow limitation, there are only few studies addressing its effects on exercise. This study aimed to assess the ability of PLB to change the breathing pattern, degree of dynamic hyperinflation (DH) and arterial oxygenation in COPD patients during exercise. Exercise tolerance was evaluated by endurance time and respiratory mechanics was evaluated by forced oscillation technique.
Vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang-2) are major mediators of angiogenesis and are induced by tissue inflammation and hypoxia. While elevated serum VEGF levels have been reported in inflammatory lung diseases, especially with hemoptysis, there was no study to evaluate the Ang-2 levels in lung inflammatory diseases according to the presence of hemoptysis, inflammatory biomarker and hypoxia.
The purpose of this study is to evaluate health status of uncontrolled Chronic Obstructive Pulmonary Disease (COPD) patients in response to treatments in clinical practice.
The purpose of this study is to compare the safety and pharmacokinetics of ciprofloxacin after inhalation of single 52.5 and 48.75 mg doses in COPD patients. In this study the 48.75 mg dose will be administered for the first time using a new high dose strength (i.e. one capsule containing 75 mg powder = 48.75 mg ciprofloxacin) formulation. Safety investigations will focus on local tolerability in the lung and evaluate whether the patient can inhale the higher amount of powder compared to the lower dose strength. Pharmacokinetics is to see how the body absorbs, distributes, breaks down and gets rid of the study drug. Results from this study will be used to decide whether the new dose strength is suitable for larger clinical trials planned for the COPD patients population.
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.
