Filter by:Goal: The main goal of this study is to develop and validate educational materials that aim to improve self-management knowledge and practices about COPD among patients in Mandarin and Cantonese-speaking communities in the Greater Vancouver Area (GVA). Objectives: "1." To assess the current landscape of COPD beliefs, perceptions and practices, as well as health literacy as it relates to Chinese Mandarin and Cantonese-speaking patients; "2." To develop effective partnerships within primary care physicians serving Chinese newcomers in the GVA' "3." To conduct focus group sessions with collaborative primary care physicians to identify common factors that contribute to under service and access barriers among patients in the target communities; "4." To assess the effectiveness of the educational materials on patients' beliefs, perceptions, practices, and health literacy related to COPD control and self-management; and "5." To improve the capacity of physicians and allied health workers in primary care settings in educating patients and their families about self-management of COPD. The implementation of the project will include the following phases: "1." Build and strengthen established partnerships with primary care practices serving newcomers in GVA; "2." Conduct an environmental scan and needs assessment (literature review, interviews and focus groups with community members and key-informants); "3." Development of story scripts, video clips and other educational materials, and relevant measurement tools; "4." Application of the video clips and other educational materials to test their effectiveness on health literacy, beliefs, and knowledge among COPD patients from the target communities; and "5." Evaluation of the usefulness of videos and other educational materials, and the project's process and outcomes.
The purpose of this trial is to investigate if roflumilast can reduce the neutrophilic inflammation at acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD). In addition, the potential benefit of roflumilast on severity and recovery periods of acute COPD exacerbations will be assessed using patient diaries and questionnaires.
Skeletal muscle is composed of two fibre types which are intertwined. Skeletal muscle weakness, particularly of the walking muscles, is an important complication of Chronic Obstructive Pulmonary Disease (COPD) but so far the investigators do not know what mechanisms drive the process. All existing studies have investigated signalling pathways in the whole muscle so they have been forced to consider type I and type II fibres together. It is possible that disease selectively affects one fibre type, most likely type I fibres which are in fact lost in COPD patients. For this reason mechanisms of disease may have been overlooked by current studies. The applicants have acquired the technology which allows type I and type II fibres in a muscle specimen to be split (by laser capture microdissection) and so signalling pathways can be assessed separately in type II and type I fibres which is what this proposal sets out to do. The proposal therefore aims to capture well characterised clinical data from 60 COPD patients and 20 age matched controls, from whom a biopsy of the main walking muscle, the quadriceps, will be taken. In the samples the investigators will assess at a fibre specific level inflammatory signalling. Surplus material will be retained for subsequent fibre specific analysis.
The aim of the present study is to evaluate the effect of aclidinium bromide 400 μg twice a day (BID) administered twice a day versus placebo on exercise endurance and on hyperinflation and dyspnoea at rest and during exercise after 3 weeks of treatment.
The primary objective is to establish the safety of the CO-rebreathing method for measuring total blood and plasma volume in CAD patients. The working hypothesis is that the CO-rebreathing method is safe in use with coronary artery disease patients and that it does not cause myocardial ischemia or cardiovascular damage.
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
Phrase: IV Indication: dyspnea symptom of chronic obstructive pulmonary disease (COPD) Objective: to evaluate efficacy and safety of tulobuterol patch combined with Tiotropium bromide for relieving dyspnea symptom of COPD Design: a multi-centre randomized parallel blank control study Case number: test group 80, control group 80, totally 160 Site number:7 Study period: 2010.9 - 2011.8
On the following tests, there would be a greater increase in the functionality of COPD patients who underwent combined therapy than in those who only exercised: a set of activities of daily living (ADLs), the six-minute walk test (6MWT), an incremental symptom-limited cardiopulmonary test (CPT), and the physical functioning scale of the Short-Form 36 quality of life questionnaire (SF-36).
Weaning of mechanical ventilation (MV) is an essential part in management of patients with Chronic Obstructive Pulmonary Disease (COPD) when critically ill. The best strategy to be used has not been established. Objective: To compare the Spontaneous Breathing Trial (SBT) in Pressure Support Ventilation with SBT through "T" tube in weaning of MV in patients with COPD. Design: Randomized Clinical Trial. Methods: This study will include patients with COPD, admitted to the Intensive Care Unit of Hospital Nossa Senhora da Conceição, undergoing MV for at least 48 hours. When considered by the care team ready for SBT, they will be randomized to one of the following strategies: SBT in Pressure Support or SBT through "T" Tube. The primary endpoint of this study will be the reduction in the days spent on MV. Other outcomes measured will be mortality, extubation and success rate, time to weaning of MV, length of ICU stay and incidence of tracheostomy.
Some patients with chronic obstructive pulmonary diseases (COPD) have large number of specific white blood cells called eosinophils in their airways. These cells are also responsible for causing episodes of worsened respiratory symptoms (exacerbations) and often cause irreversible damage to the airways . This subset of COPD patients often require oral steroids to bring down the number of eosinophils in their airways. Steroids have harmful effects on several of our body systems like bones, blood pressure, blood glucose control and can cause recurrent infections. Mepolizumab is a drug that specifically targets eosinophils reducing the number in the airway. This drug has been shown to be effective in decreasing exacerbation rates and time to exacerbation in asthma patients with eosinophils in their airways. Targeting eosinophils in COPD patients has been shown to reduce severe exacerbations. Hence it is likely that COPD patients with eosinophils in their airways will benefit similarly and have reduced rates and time to exacerbation. Study Hypothesis:Does mepolizumab decrease sputum eosinophils in patients with fixed airflow obstruction (COPD) and eosinophilic bronchitis?
