Active clinical trials for "Lung Diseases"

This is an early feasibility study to investigate whether transcutaneous electrical stimulation applied to the abdominal wall muscles synchronous with voluntary exhalation can be used to support ventilation and affect hyperinflation in patients with chronic obstructive pulmonary disease. As part of this study, the effect of a range of stimulation intensities and stimulation timing profiles will be explored.

The purpose of this randomized controlled trial was to evaluate the effects of a respiratory rehabilitation exercise training package on dyspnea, cough, exercise tolerance, and sputum expectoration of hospitalized elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Using purposive sampling, 61 participants were recruited and randomly assigned to either the experimental group (n = 30) or the control group (n = 31). The experimental group participants received the respiratory rehabilitation exercise training twice a day and 10-30 minutes per session for four days. The control group participants received usual care and health education. Data were collected at baseline and at the end of the four-day intervention.

The main purpose of this study is to determine feasibility and effects of tai chi and mind-body breathing in patients with COPD.

The objective is to study the cognitive functions in patients with chronic obstructive lung disease (COLD) and patients with interstitial lung disease (ILD) compared to healthy controls. The cognitive functions are tested with and without oxygen therapy to clarify the effect of oxygen therapy. Driving simulations is used to test the cognitive functions. The hypothesis is that patients with chronic lung disease have decreased cognitive functions and that oxygen therapy will increase their cognitive functions.

Among many other causes, Bronchial obstruction in Chronic Obstructive Pulmonary Disease (COPD) is also caused by inflammation of peripheral airways walls. Neutrophils and other inflammatory mediators like Interleukin-6 (IL6), Interleukin-8 (IL8), Interleukin-1 alpha (IL-1 alpha),Interleukin-1beta (IL-1 beta), Tumor Necrosis Factor alfa (TNF-alfa), Reactive Oxygen Species (ROS), Leukotriene B4 (LTB4), Nitric Oxyde (NO) are implicated in the inflammation. NO is produced in response to physical and chemical stress on bronchial epithelium and plays a critical role in small airways remodelling Exhaled NO concentration is usually used to monitor bronchial inflammation The relationship between stretch and strain of small airways and bronchial inflammation is not well understood. The investigators hypothesis is that cyclic opening and closure of peripheral obstructed airways through the consequent stretching and strain acting on them can provoke an inflammatory response which can be monitored by exhaled NO. The pharmacological effects of bronchodilators may play a role on bronchial inflammation by reducing the stretching stress on bronchiolar walls thus reducing the production of NO in exhalate Data about these physiopathological aspects is missing in literature.

To determine if stair climbing can be used as a measure of progress in persons with pulmonary disease.

This study seeks to study the effectiveness of a short mindfulness based pulmonary rehabilitation program prior to a surgical resection in patients with lung cancer and severe Chronic Obstructive Lung Disease (COPD).

The purpose of the study is to investigate the tolerability and safety of AZD2423 in Patients with chronic obstructive pulmonary disease.

This project will evaluate the translation of the Gold (the Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Pulmonary Disease) COPD guidelines into primary care practice. During phase I, a needs assessment will evaluate barriers and facilitators to implementation of COPD guidelines into clinical practice through focus groups of primary care patients and providers. Using formative evaluation and feedback from the focus groups, three tools will be developed, refined and pilot tested. The effectiveness of the materials developed in phase I will be tested in phase II (a randomized clinical trial conducted with one year of intervention within non-academic primary care practices) regarding physician performance of COPD guideline implementation and improvement in the clinically relevant outcomes (appropriate screening, diagnosis and management of COPD) compared to usual care.

The purpose of this study is to characterize the clinical, physiologic, and molecular profiles of healthy participants, participants with mild, moderate, and severe asthma; and participants with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).
