Filter by:The primary purpose of this study is to determine the effectiveness of a hospital-based intervention, using motivational interviewing and interactive voice response (IVR), to reduce hospital readmissions within 90 days of enrollment compared to usual care, for patients with heart failure and chronic obstructive pulmonary disease.
The overall objective of this study is to assess the efficacy and safety of treatment with PT003 (GFF MDI), PT005 (FF MDI), PT001 (GP MDI), and open-label tiotropium bromide inhalation powder compared with each other and Placebo MDI over 24 weeks in subjects with moderate to very severe COPD.
In previous studies we demonstrated that endogenous opioids (inhibitory neuropeptides) modulate the perception of breathing difficulty in patients with chronic obstructive pulmonary disease (COPD). Recently, we found that antagonism of substance P (an excitatory neuropeptide) with aprepitant did not affect the perception of breathing difficulty. However, after administration of aprepitant, blood levels of both substance P(+ 54 ± 39%) and beta-endorphin (+ 27 ± 17%) increased significantly. As these blood levels reflect cellular/tissue activity, we postulated that the concomitant release of excitatory (substance P) and inhibitory (beta-endorphin) neuropeptides had opposing effects (counterbalanced each other) on the perception of breathing difficulty. The objective of the present study is to further examine the possible role of substance P on the perception of breathlessness. We propose to administer oral aprepitant and oral placebo in a randomized clinical trial in patients with COPD. However, four hours after patients take these medications, intravenous naloxone will be administered in order to block the effects of endogenous opioids (beta-endorphin) on opioid receptors. Five minutes later, patients will breathe thru a tube with fine wire mesh to provoke breathing difficulty, and then provide ratings of the intensity and unpleasantness of breathlessness every minute. The two competing hypothesis of the study are: 1. if breathlessness ratings with aprepitant/naloxone = placebo/naloxone, then substance P has no effect on perception of breathing difficulty; 2. if breathlessness ratings with aprepitant/naloxone ≠ placebo/naloxone, then substance P has an effect on perception of breathing difficulty.
The aim of this study was to assess the effectiveness of the implementation of walking urban circuits in increasing the level of physical activity and exercise capacity in severe chronic obstructive pulmonary disease (COPD) patients after being enrolled in a pulmonary rehabilitation program.
- 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.
Influenza disease causes significant morbidity and mortality in the Unites States each year. Although influenza can cause morbidity in otherwise healthy individuals, adults with chronic lung disease have significantly increased rates of hospitalization from influenza-related illnesses compared to healthy adults. Influenza vaccination is the primary means of preventing influenza disease. Annual influenza vaccination is recommended for all individuals 6 months of age and older in the United States. Influenza vaccination rates are sub-optimal, however. Patient reminder/recall has been shown, in multiple studies across a variety of age groups and health conditions, to increase immunization rates. However, the effectiveness and cost-effectiveness of different types of reminder/recall has not been well-studied, particularly in adults. In the fall of 2012, the Population and Prevention Services (PPS) Department at Kaiser Permanente Colorado (KPCO) is using 3 different reminder strategies for influenza vaccination among adults with asthma and chronic obstructive pulmonary disease (COPD). The objective of this study is to provide a rigorous evaluation of which strategy is more effective and more cost-effective, to promote influenza vaccination.
Conventional approaches to relieve dyspnea (respiratory discomfort) in chronic obstructive pulmonary disease (COPD) have focused on improving respiratory motor drive (e.g., hyperoxia) and/or dynamic respiratory mechanics (e.g., bronchodilators). Although these approaches yield meaningful symptom improvements there remains many COPD patients incapacitated by dyspnea. Accumulating evidence suggests that abdominal binding (AB) is a potentially novel method of improving respiratory muscle function and, by extension, dyspnea and exercise tolerance in COPD. Thus, the purpose of this randomized, cross-over study is to test the hypothesis that AB improves exertional dyspnea and exercise tolerance in symptomatic patients with COPD by improving dynamic respiratory muscle function. To this end, the investigators will examine the effects of AB on detailed assessments of baseline pulmonary function (spirometry, plethysmography), dyspnea (sensory intensity & affective responses), neural respiratory drive (diaphragm EMG), contractile respiratory muscle function (esophageal, gastric & transdiaphragmatic pressures), ventilation, breathing pattern and cardiometabolic function during symptom-limited constant load cycle exercise (75% Wmax) in 20 patients with GOLD stage II/III COPD.
The investigators designed the current study with the main objective of determining whether Whole Body Vibration Training (WBVT) alone improves muscular force and/or modifies the functional capacity parameters in severe Chronic Obstructive Pulmonary Disease (COPD) patients referred to a rehabilitation programme.
To determine if stair climbing can be used as a measure of progress in persons with pulmonary disease.
Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory (lung) disease that makes it harder to breathe over time. To date, there is no cure for COPD, but it can be managed when diagnosed and proper medical care is provided. The purpose of this study is to determine if diagnosis and guided therapy with the use of spirometry is related to better patient outcomes (the condition of a patient's health) compared to usual care which may or may not include the use of spirometry. Spirometry is a standardized test used in medical practice that measures how much air your lungs can hold and how forcefully you can breathe out. For this study, the investigators will compare two groups: 1) intervention (treatment) group and 2) usual care group (control). The intervention group will have a spirometry test and the results will be provided to the primary care physician. The usual care group will not initially have a spirometry test. Both groups will be followed for outcomes.
