Filter by: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.
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.
The LTRC will facilitate histopathological research of pulmonary diseases by collecting lung tissues from donors and preparing and distributing collections of tissue specimens to researchers within and outside the LTRC. Collections of specimens will be linked to individual clinical data appropriate to the particular disease. The primary goal of the LTRC is to identify participants with suspected lung cancer or metastatic disease who are willing to provide informed consent for research use of their specimens and data. Secondarily, the LTRC investigators intend to collect clinical data, limited exposure data, physiologic studies, and radiographic studies from these participants.
Purpose: In a randomized controlled trial we will assess the effect of early pulmonary rehabilitation in patient with an acute exacerbation of chronic obstructive lung disease (AECOPD).
The purpose of this study is to evaluate the dose-response relationship of different doses of CHF6001 and to identify the optimal dose (s) in terms of benefit/risk ratio for further development in the target patient population.
To determine whether high-intensity NPPV, compared with low-intensity NPPV, could reduce the need for endotracheal intubation during hospitalization in patients with an AECOPD and hypercapnia.
