Utility of Remote Lung Auscultation in Transitions of Care After Pulmonary Exacerbations of COPD...

Chronic Obstructive Pulmonary Disease (COPD)

Listening to breath sounds with the stethoscope/auscultation is used by pulmonary physicians in conjunction with pulmonary function, signs and symptoms, oxygen saturation and diagnostic testing to admit, follow and discharge patients from hospital. Of these, only auscultation routinely ceases upon discharge from Hospital. Healthcare utilization statistics have shown that for more than a decade, readmission after discharge for an exacerbation of COPD or severe asthma (or chronic heart failure) remains a major problem. The Strados RESP Biosensor has been designed to extend the range of lung sound recording both geographically and temporally to improve the standard of care when access to continuous monitoring has been replaced by periodic or no monitoring. The primary purpose of this study is to assess the associations between RESP Biosensor-acquired lung findings and subjective measures of respiratory symptoms as measured by validated measurement tools, and objective measure of respiratory physiology as determined by home spirometry

Macrophages in Smokers' Lung

Chronic Obstructive Pulmonary DiseaseEmphysema1 more

Cigarette smoking causes an increase in inflammation in the lungs. In about 20% of smokers this inflammation leads to damage in lungs including making holes in the lung tissue. This damage can not be repaired and these people find it very difficult to breathe. One of the problems with this disease called chronic obstructive pulmonary disease, or COPD for short, is that by the time patients visit their doctor with symptoms, the damage has already been done. At the moment, there is no way to predict which smokers will go on to develop COPD. The aim of this research is to look at smokers who breathe normally and use an imaging technique called a CT scan, to look at their lungs in more detail. Some of these people will have spots on their scan which may be caused by inflammation. We want to look at the cells at these spots to see if they make more proteins and enzymes that cause lung damage when compared to people that do not have these spots. We would then be able to predict which smokers are likely to develop COPD and treat them early before they have damaged their lungs.

Markers for Chronic Obstructive Pulmonary Disease (COPD)

Healthy Non-smokersCurrent Smokers1 more

The primary aim of this study is to exploit a difference between COPD patients, chronic smokers without COPD and healthy non-smoking subjects. This will help to assess the utility of inflammatory and oxidative markers in exhaled air and sputum and to compare them with the lung function, clinical parameters and computerised tomography (CT).

Systemic Endothelial Abnormalities in COPD

Chronic Obstructive Pulmonary Disease

The 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.

Tiotropium Plus Olodaterol vs Inhaled Corticosteroids (ICS) Regimens in the Portuguese Primary Care...

Pulmonary DiseaseChronic Obstructive

What are the differences between patients prescribed a new maintenance treatment for Chronic Obstructive Pulmonary Disease (COPD) with tiotropium/olodaterol (TIO/OLO) or Inhaled Corticosteroids (ICS)-containing regimens in terms of sociodemographic, anthropometric and clinical characteristics?

A Prospective, Observational Study of COPD Patients in U.S. Hospitals

Chronic Obstructive Pulmonary Disease

This 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 Disease

Identify 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 Disease

Nottingham 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.
