Filter by:This is a developmental project with two phases. The first phase will adapt an existing web-based intervention to incorporate mind-body exercises to develop a multi-modal intervention to promote physical activity in patients with COPD and HF. The second phase will pilot test this new intervention in a longitudinal study (subjects randomized to intervention or usual care).
Chronic obstructive pulmonary disease (COPD) is a common smoking-related lung disease. Patients with COPD are at increased risk of developing cardiovascular disease such as heart attacks and strokes. A simple measurement called arterial stiffness is a good assessment of how likely people are to have cardiovascular disease, both in healthy populations and those with COPD. Aortic Pulse wave velocity (aPWV) measures arterial stiffness, Pulmonary Rehabilitation (PR) - a 6 week supervised group exercise and education class - is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbations. However, the effect of PR on cardiovascular risk in COPD is controversial as two small positive studies suggested benefit and one larger study did not. Investigators have recently shown that cardiovascular risk is higher in those COPD patients who get the most infections (exacerbations). PR is an effective intervention for preventing COPD exacerbations. Logically, the exercise component would be expected to reduce cardiovascular risk too. Investigators want to identify which patients with COPD get cardiovascular benefit from a PR programme and why others do not. Investigators propose to measure aPWV before and after PR. Investigators will then classify participants as responders or non-responders defined as the presence or absence of a significant improvement in aPWV. Investigators will be collecting demographic and clinical information including daily physical activity level and how effective the PR has been to enable the investigators to identify the characteristics of patients who do, and do not achieve cardiovascular risk reduction in response to PR in COPD. This will inform on better design of PR programmes for people living with COPD.
Hyper polarized xenon-129 MRI (HXe MRI) is a unique imaging test which can detect how air is flowing in and out of lungs and how oxygen can move from inhaled air into the blood. Chronic Obstructive Pulmonary Disease (COPD) is a disease in which patients develop narrowing of airways, thus, having difficulties breathing air in and out their lungs and also damaging the lung tissues which patients need to move oxygen from the air into blood. In this study, two drugs which are already approved by FDA (Anoro and Arnuity) will be administered to patients who are already known to have COPD. While patients are being treated with these two drugs (one drug at a time over a month), lung health by using usual testing methods (CT scan of the lung, pulmonary function test, and blood test) will be assessed in addition to HXe MRI. The goal of this study is to prove that the HXe MRI is an excellent imaging test to show the state of lung health among COPD patients and also to obtain new informations on how lung health changes with drugs that are already approved by US FDA. This work is anticipated to help develop HXe MRI as a new clinical test which can guide how to treat patients with COPD and if new therapies can improve lung health of patients with COPD.
Regular physical activity has been found to be important in maintaining health and well-being in people with COPD. The purpose of this study is to test new technology and health coaching aimed to help people with COPD become more physically active in their daily lives.
This study aimed to explore the associations between constitutions of traditional Chinese medicine (TCM) and common disease (CD). A large-scale, community-based, cross-sectional study was performed to investigate the associations. A total of 3748 participants were available for analysis in this study. The assessment of constitution of TCM was based on recommendations of Association Chinese Medicine in China. In this study, the diagnosis of CD was based on self-reported medical history. The associations were analyzed using univariate and multivariable logistic regression (MLR).
Taken recent literature together, there is a sufficient number of trials investigating the effect of different oxygen devices. However, studies comparing oxygen delivery via portable oxygen concentrator (POC) and liquid oxygen device (LOD) with appropriate exercise testing and sufficient power are missing. Given that walking is the most important activity of daily life to preserve the maintenance and to participate in social life, we aim to investigate the effects of two different oxygen delivery systems during walking in hypoxemic COPD patients (POC vs. LOD). The endurance shuttle walk test (ESWT) is well validated for measuring endurance walking capacity in COPD patients with good repeatability. The advantage of this test over the 6MWT is that the ESWT is performed at 85% of the individual maximum which is close to the intensity of typical daily activities. Due to the fact that the ESWT enables us to determine the maximum duration of exercise and to compare values at isotime (at the point of time when the shortest of the 3 ESWTs ends), we use the ESWT as exercise test in our trial.
People living with Chronic Obstructive Pulmonary Disease (COPD) have problems with their balance and a high incidence of falls compared to those of a similar age. Pulmonary rehabilitation is recommended for people with COPD, however, these training programs do not typically include balance training or fall prevention strategies. In this study, patients with COPD who report problems with their balance or have had a fall in the last two years will be assigned to a treatment group (balance training plus pulmonary rehabilitation) or control group (standard pulmonary rehabilitation). We will record the number of falls using monthly diaries and evaluate patient's balance, strength, confidence and quality of life.
The Copenhagen City Heart Study is an ongoing cardiovascular population study initiated in 1976 which has examined approximately 25,000 individuals from the general population. The initial sample has been re-invited up to four times and supplemented by younger individuals. The study includes questionnaires, clinical assessment and biomarkers. The population have been followed in a number of outcome registries and more than 900 scientific papers have been published.
This study will develop and experimentally test the efficiency of a neurofeedback training protocol vs. varenicline use for smoking cessation.
This cross-sectional survey study is intended to describe the characteristics of adults in 4 US states with regards to respiratory symptoms and tobacco exposure, utilizing an existing state-administered, CDC overseen Behavioral Risk Factor Surveillance System telephone health survey. The primary goal of study is to describe the sociodemographics, health behaviors, and presence of chronic diseases in persons with or at risk of having chronic obstructive pulmonary disease.
