Systemic Endothelial Abnormalities in COPD
Chronic Obstructive Pulmonary DiseaseThe purpose of this project is to validate the peripheral arterial pressure waveform measurements technique of RAAP (radial artery applanation tonometry), in patients with moderate and severe COPD (Chronic Obstructive Pulmonary Disease), and to assess the degree of systemic endothelial dysfunction in these patients compared to cigarette smokers with normal lung function and non-smokers with normal lung function.
A Prospective, Observational Study of COPD Patients in U.S. Hospitals
Chronic Obstructive Pulmonary DiseaseThis is an observational study to evaluate the relationship between pulmonary function and the patient reported health-related quality of life (HRQoL) and chronic obstructive pulmonary disease (COPD) related admissions. Patients with COPD will be approached to participate in the study. Pulmonary function will be measured on consented, eligible patients. The pulmonary function measurement collected will be used for cohort assignment. The prospective follow up period will monitor the cohorts for evidence of readmission and to assess HRQoL.
Biologic Basis Of Increased Susceptibility Of Smokers To Pulmonary Infection With Mycobacterium...
TuberculosisChronic Obstructive Pulmonary DiseaseIdentify a biologic (molecular) basis for the increased susceptibility of cigarette smokers to pulmonary TB (Mtb) by testing the hypothesis that smoking reprograms AM polarization towards a distinct phenotype associated with impaired host defense function against Mtb and that normalization of that phenotype via therapeutic modulation of the Alveolar Macrophage (AM) polarization or smoking cessation can restore the anti-Mtb host defense function of AM.
Evaluation of Remote Patient Monitoring.
Congestive Heart FailureChronic Obstructive Pulmonary DiseaseNottingham Primary Care Trust has launched telemonitoring to support: independent living and self-management ability of people with congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD) and co-morbidities; and reduce the health care utilisation associated with these patients, including the number of hospitalisations, GP visits and community matron and specialist community nurse home visits. The Multidisciplinary Assessment of Technology Centre for Healthcare (MATCH) will evaluate the technology and its impact of this telemonitoring system on quality of care (i.e. process measures), patient outcomes and direct healthcare costs from an NHS perspective.
Bronchioscopic Lung Volume Reduction (BLVR)
Chronic Obstructive Pulmonary Disease (COPD)For patients with emphysema, lung volume reduction by insertion of endobronchial valves could be an expedient approach to improve the diaphragm function and the strength of breathing muscles. Therefore in the present study investigators intend to examine, whether the lung volume reduction by valves might improve the physical capacity and the quality of life.
Hospitalary Chronic Obstructive Pulmonary Disease Registry
COPD ExacerbationsDeathThe purpose of this study is to create an institutional registry of Chronic Obstructive Pulmonary disease through a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival.
Registry for Chronic Obstructive Pulmonary Disease With Anxiety and Depression in China
COPDAnxiety1 moreAnxiety and depression are common comorbidities of chronic obstructive pulmonary disease (COPD). However, the exact prevalence is not known in China. COPD patients with anxiety and depression tend to have more severe symptoms and worse prognosis, but the related evidences are not strong enough. The study aim to investigate the prevalence and long-term outcome of anxiety and depression in COPD.
Registry for Chronic Obstructive Pulmonary Disease With Pulmonary Hypertension in China
COPDPulmonary HypertensionPulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD). It is reported that over half of COPD patients develop pulmonary hypertension. COPD and pulmonary hypertension may have pathological or genetics interactions so that patients having both disorders tend to have poor prognosis. Echocardiography is widely used to detect pulmonary hypertension, but it's not accurate enough. Therefore, high-quality data reflecting the prevalence, disease course and outcome of pulmonary hypertension in COPD is very limited in China. The aim of the study is to detect pulmonary hypertension with right heart catheterization, describe its outcome in Chinese COPD patients and explore the underlying interaction mechanism.
Evaluation of Novel Lung Function Parameters and Quantitative Computed Tomography (qCT) in Patients...
Chronic Obstructive Pulmonary DiseaseBronchial Asthma1 moreCurrent diagnostic tools used in pulmonary disease often do not meet the challenges set by the respective pathophysiology. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various pulmonary diseases.
The Differences of Muscle Activity Between Patients With COPD and Healthy Adults
Chronic Obstructive Pulmonary DiseaseThe purpose of this study attempts to investigate the differences and relationships of respiratory parameters, muscle activity, and dyspnea during ADL between patients with COPD and age-matched healthy participants.
