Filter by:For this study a resistance bout will be performed in order to promote the robust response of protein synthesis. Type II muscle fibers often exhibit more atrophy than type I fibers in COPD subjects therefore specifically targeting them in an exercise protocol could have more beneficial outcome for these individuals.
This study is designed as a prospective study, with the primary endpoint being changes in pulmonary hemodynamic parameters after ELVR in patients with severe emphysema. Secondary endpoints will be changes in lung function parameters, exercise capacity, and QoL.
This is a cross sectional case controlled study to assess lung microbiome and inflammation in smokers with and without Chronic Obstructive Pulmonary Disease (COPD). Investigators will look at active bacterial metabolic pathways in the lower airways using metagenomic and metabolomic approaches an assess relationships among microbiome, metagenome, metabolome and host immune responses in COPD and controls. Investigators believe COPD cases will have higher prevalence of pneumotype supraglottic predominant taxa (SPT) than matched controls.
Development of pulmonary hypertension (PH) in chronic lung diseases has both functional and prognostic implications . PH in Lung diseases is usually mild to moderate with preserved cardiac output, and evolves slowly alongside the progression of lung disease and hypoxemia . However, a minority of patients develop severe PH with elevations in pulmonary artery pressure that have been described as ''out of proportion'' to the underlying disease . The aim of this study is to compare the characteristics and outcomes of consecutive patients with PH-due to lung diseases diagnosed at our specialist referral center over a 1-year period.
COPD patients will be recruited and assigned into one of each group: 1) Control group or 2) Yoga group. In Yoga groups, subjected will be asked to participate in Modified Dantien Yoga training for 12 weeks (3 times/week, 60 min/time). The subjects will be evaluated their pulmonary function, functional fitness performance, dyspnea score, and quality of life at baseline and after 12 wk training.
Weight loss commonly occurs in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disorder (COPD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in CHF and COPD patients, but patients also have reductions in fat mass and bone density, independent of the severity of the disease state. The purpose of this study is to provide detailed insight in disease related gut function by obtaining information on gut permeability, digestion and absorption of glucose, fat and protein in CHF and COPD patients compared to matched healthy controls. This will provide required information that is necessary to implement new strategies to develop optimal nutritional regimen in CHF and COPD.
The London COPD exacerbation (EXCEL) cohort builds on an established cohort started in 1995 and designed to study COPD exacerbations and their impact on health-status and disease progression.
The purpose of this study is to determine whether the selected osteopathic techniques have a positive impact on the residual volume decrease in patients with chronic obstructive pulmonary disease with severe and very severe airflow limitation in comparison to the manual therapy not aimed to decrease hyperinflation (placebo).
The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.
Subjects aged 18-85 with lung disease will undergo hyperpolarized Xenon 129 (129-Xe) MRI and Pulmonary Function testing for the development of tools to evaluate the Apparent Diffusion Coefficient (ADC), ventilation defect percent (VDP) and pulmonary gas exchange measurements obtained by analysis of hyperpolarized 129-Xe MRI.
