Active clinical trials for "Lung Diseases, Obstructive"

We hypothesize that ongoing and more severe airway inflammation in COPD may result from the impairment in activation of innate immune response

Previous studies suggest that treadmill exercise may be a more relevant exercise stimulus than the cycle ergometer to demonstrate benefits with bronchodilator therapy in patients with COPD. The hypothesis of the study is that patients with COPD will exhibit greater improvements in exercise endurance and breathlessness with arformoterol compared with normal saline during treadmill walking than with cycle exercise.

The aim of this study is to investigate the exercise capacity in COPD-patients performing a vibration training additional to a standard three-week rehabilitation program in comparison to patients performing merely a rehabilitation program.

The aim of this study is to investigate the change of physical activity in COPD-patients performing a whole body vibration training additional to a standard three-week rehabilitation program in comparison to patients performing merely a standard rehabilitation program.

The purpose of this study is to determine whether or not vitamin D supplementation can improve physical performance in persons with severe chronic obstructive pulmonary disease (COPD).

The purpose of this study is to evaluate the pharmacodynamics (bronchodilation) of single doses of inhaled LAS100977 in COPD patients.

The objective of this study was to evaluate the use of high frequency chest wall oscillation (HFCWO) early in the treatment of adults hospitalized for acute asthma or chronic obstructive pulmonary disease (COPD).

Patients living with advanced chronic diseases (ACD), such as congestive heart failure (CHF) and chronic obstructive lung disease (COPD) present substantial care and economic challenges for the health care system due to frequent emergency room visits and acute care hospitalizations. Morbidity and mortality is high in these complex populations, and patient quality of life is often compromised. Care of patients with ACD occurs across health care sectors, by providers in the acute, primary and community settings. Despite recent efforts to enhance the care of patients with ACD, through multidisciplinary disease management programs, variations and gaps exist along the continuum of care. The available evidence suggests that there are opportunities to optimize the primary care of patients with ACD. We are proposing to build upon the current evidence and guidelines for disease management programs, our existing specialized resources, our existing primary care practices, and develop and test a model of care that is primary care based, sensitive to the unique demands and characteristics of different primary practices. Our goal is to design linkages and care strategies of relevance and importance to the primary care providers who care for patients with advanced COPD and CHF. This demonstration project is a randomized controlled clinical trial of the RoadMAP program (intervention) delivered by a Primary Care Nurse Specialist (PCNS) compared to usual care (control group). The primary outcomes will be degree of adherence to clinical practice guidelines. Secondary outcomes will be patient satisfaction, quality of life, use of community-based services, number of emergency room visits, and number of hospitalizations.

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.

People with COPD have more air in their lungs than other people (this problem with high lung volumes is called "hyperinflation"). Unfortunately this is unhelpful as breathing at higher lung volumes requires more effort and contributes to breathlessness. When anyone exercises, they breathe more quickly. People with COPD have narrowed airways, which makes breathing out difficult. When they breathe more quickly they may not be able to breathe out fully before they need to take the next breath in. This means that the volume of air in their lungs tends to increase further during exercise, which makes breathing even more difficult. This problem is called "dynamic hyperinflation". Pulmonary rehabilitation is one of the most helpful interventions for people with COPD and most of the benefit gained is from exercise. Anything that helps people increase the amount of exercise they can perform should lead to further improvements. Non-invasive positive pressure ventilation is a method of supporting a person's normal breathing. The ventilator delivers a flow of air at low pressure as you breathe out, which helps patients to breathe out more completely. The device also detects when patients start to breathe in and delivers a stronger flow of air at a higher pressure, helping them to take a deeper breath in. Previous research studies have shown that when people with COPD use non-invasive ventilation during exercise they are able to exercise for longer and are less breathless. The purpose of this study is to assess whether a new portable non-invasive ventilation device, called the VitaBreath, helps people with COPD recover from breathlessness during the exercise breaks more quickly (by reducing "dynamic hyperinflation", described above) and to exercise for longer overall. The VitaBreath device is small and light, weighing 0.5 kilograms (just over one pound). It is handheld and battery powered.
