Filter by:The purpose of this study is to assess the prevalence of COPD among individuals aged 35 - 59 years based results of spirometry before and after bronchodilator, presence of structural changes in lungs (emphysema, inflammatory changes and thickening of the walls of the large and small airways)detected by computer tomography as well as the symptoms of COPD. The study has three study groups: smokers of conventional cigarettes; those who had quit smoking 1 - 5 years ago, and those who haven't smoked cigarettes.
Main objective: To compare the level of physical activity (PAL) at 12 months in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) between those who completed a health education program and those who did not. Study patients. Subjects older than 35 years; diagnosis of moderate to very severe COPD (FEV1 <80% predicted), established at least 3 months; current or former smoker with an accumulated consumption >10 packs x year; and hospital admission for COPD exacerbation. Design. Randomized, parallel and open-label clinical trial, controlled with conventional treatment. Intervention: During hospitalization, selected patients will receive conventional treatment. At discharge, they will be randomized (1:1) to control group [treatment and follow-up according to conventional clinical practice] or intervention group [in addition to conventional treatment and follow-up, the patients will be referred to a nursing consultation for perform two health education sessions, at 15 and 30 days after hospital discharge]. Measurements. At 15 days and 12 months after discharge, the following determinations will be made: anthropometric characteristics; clinical evaluation (smoking history, date of COPD diagnosis, comorbidities, current medication; health care utilization; moderate or severe COPD exacerbations); questionnaires (mMRC, Charlson, COPD-specific co-morbidity test (COTE), COPD Assessment Test (CAT) and LCADL), spirometry and six-minutes walking test; and evaluation of daily physical activity using an accelerometer.
Obstructive lung disease is an increasing global health problem of pandemic proportions, with COPD alone affecting >10% of the population. Smoking is the main and most well studies risk factor for developing COPD. However, chronic airway obstruction also in never-smoking populations has recently been recognized as an increasing health problem. Prematurely born children, particularly survivors of bronchopulmonary dysplasia (BPD), defined as the need for oxygen therapy up to the 28th day of life for children born prior to gestational week 32, have an increased incidence of both airway obstruction and hyper-reactivity, both representing major risk factors for developing COPD, or asthma, later in life. The purpose of this study is to perform in-depth clinical and molecular characterizations of of the lungs of survivors of BPD as they enter adulthood, and compare these profiles to relevant control groups (individuals with mild asthma, healthy prematurely born, and healthy individuals born at full term). Specifically, alterations at the epigenetic, mRNA, microRNA, protein and metabolite level as well as associated molecular pathways critical in the pathological mechanisms of obstructive lung disease related to premature birth and BPD will be identified.
The aim of the study is to test the hypothesis that treatment of sleep disordered breathing (SDB) in patients with comorbid chronic obstructive pulmonary disease (COPD) and/or heart failure (HF) with positive airway pressure (PAP) is associated with reduced risk for hospitalizations and death, lower health care utilization, and greater cost-effectiveness.
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease primarily caused by smoking. Pulmonary rehabilitation (PR) is an evidence-based, interdisciplinary, and comprehensive intervention for COPD patients that includes patient assessment, exercise training, and self-management education to promote behavior changes. PR has been shown to be the most effective strategy to improve clinical health outcomes, and is now considered to be a standard of care intervention for individuals with COPD who remain symptomatic despite optimal drug therapies. Despite considerable evidence supporting the effectiveness of PR at enhancing clinical outcomes, it is unclear if PR influences the behaviors that promote COPD management (i.e., physical activity, medication adherence, self-managing exacerbations). In collaboration with the local clinical staff as well as national colleagues and the Canadian Thoracic Society, a new national pulmonary rehabilitation program has been co-developed that is designed to increase physical activity, medication adherence, and skills to help manage chronic lung diseases. The new program aims to increase people's confidence and autonomy for performing disease-management behaviors, and has been designed to be more effective at increasing physical activity, medication adherence, and disease management skills than previous pulmonary rehabilitation programs. The program is designed to be delivered within different settings of practice, including traditional PR centers, satellite sites (i.e., sites that are remote from the major institutions),with the use of Tele-health and web-based resources, and primary care medical centers. The effectiveness of the new Standardized Canadian PR program will be assessed relative to the traditional PR program. This trial is an important step towards establishing the necessary evidence that will then enable us to work on dissemination and implementation of this new standardized PR program across the country.
In a former study, the investigator observed significant differences in the response to pulmonary rehabilitation between COPD patients with the "normal" genetic variant of alpha-1 antitrypsin (PiMM) and those with a homozygous deficient variant (PiZZ) (Jarosch et al., 2016, DOI: 10.1159/000449509). PiZZ COPD patients showed less improvement in exercise capacity compared to PiMM patients. This latter finding was mirrored by an increase of oxidative myofiber type I proportion - that is important for aerobic exercises in daily life - in PiMM but not PiZZ patients. Based on this finding of impaired skeletal muscle adaptation, the aim of this study is to compare the effects of pulmonary rehabilitation including exercise training on a) specific enzymes of energy metabolism reflecting the oxidative capacity of the skeletal muscle and b) the analogue gene expression of these oxidative enzymes in a cohort of PiMM and PiZZ COPD patients.
Limb muscle dysfunction, characterized by loss of capillaries, is amongst the most troublesome systemic consequences of chronic obstructive pulmonary disease (COPD) leading to poor functional status and premature mortality. One prevailing hypothesis stipulates that modification in the expression of miR-204 leads to change the regulation of angiogenesis in vastus lateralis of patients with COPD when compared to controls.
The purpose of this study is to determine the effectiveness of telemedicine multifaceted intervention in symptoms patients with chronic obstructive pulmonary disease.
This Quality Enhancement Research Initiative (QuERI) project is designed to determine efficacy and acceptance of an intervention method to provide primary care providers with patient-tailored electronic consults and corresponding unsigned orders for de-implementation of inhaled corticosteroids (ICS) for patients with COPD when ICS are not indicated by guidelines.
In patients with Chronic Obstructive Pulmonary Disease (COPD) lifestyles with lower physical activity levels have been shown to increase the risk of hospital admissions and shorten survival rates. An established process in increasing activity levels is to undergo pulmonary rehabilitation classes. The investigators wish to identify whether the use of activity monitors,which will provide feedback on activity levels, will increase the physical activity levels of patients with COPD outside of the supervised pulmonary rehabilitation sessions.
