Filter by:The Breathe Ventilator is a lightweight, wearable ventilator that has received U.S. FDA clearance for use in patients with respiratory difficulty. The investigators believe that the Breathe NIOV system will reduce the work of the diaphragm and breathing by providing added tidal volume and oxygen. This will be a study in 14 patients with severe-to-very severe chronic obstructive lung disease (COPD) to assess their work of breathing while using the NIOV system as measured by esophageal and stomach pressures.
The primary objective of this study is to assess the efficacy of Glycopyrrolate/Formoterol Fumarate MDI relative to individual components (GP MDI and FF MDI) in subjects with moderate to severe COPD
Most patients with chronic lung disease underestimate their actual walking ability due to low confidence. To better understand the relationships between lung function, self-efficacy for walking (confidence in ability to walk a defined distance), actual walking ability for the same distance gait speed and physical activity level-PAL- (total energy expenditure/resting metabolic rate). Quality of life, self efficacy for activity questionnaires, physical activity level measurement, 4-meter gait speed and 6-minute walk distance will be measured.
This project proposes to test the hypothesis that osteopathic manipulative treatment (OMT) given to patients with moderate to severe chronic obstructive pulmonary disease (COPD) enrolled in a 12-week pulmonary rehabilitation program (PRP) will result in improved respiratory pump function over and above that seen in sham and control groups. Specifically, we will study the effects of three OMT techniques: (a) thoracic inlet indirect myofascial release; (b) rib raising with continued stretch of the paraspinal muscle to the L2 level; and (c) cervical paraspinal muscle stretch with suboccipital muscle release. The key clinical readouts will include: spirometry, P100 (and index of diaphragm and inspiratory muscle efficiency), maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), as well as laser evaluation of chest wall excursion. Supplementing these objective parameters will be several more subjective clinical outcome measures: exercise tolerance (6-minute walk test), dyspnea (shortness of breath questionnaire), and quality of life questionnaire. Finally, an attempt will be made to correlate biochemical alterations that may shed light on the biological mechanism underlying the OMT procedures.
This study will assess the safety and pharmacokinetics of GSK573719 and GSK573719/vilanterol combination in healthy subjects and subjects with moderate hepatic impairment. The results of this study will provide guidance on the use of the product in patients with hepatic impairment.
The purpose of this study is to compare the efficacy and cost difference of using a parenchymal stapling device versus hand sewing for a pulmonary lobectomy in patients with lung disease (mass or others).
This study will assess the efficacy and safety of QVA149 compared to tiotropium plus formoterol in patients with moderate to severe COPD.
The purpose of the study is to propose that roflumilast is associated with meaningful reductions in biomarkers of pulmonary inflammation and sputum neutrophilia, including confirmation of previously described results, and correlate these findings with improvement in pulmonary function, sputum scores, and quality of life in stable moderate to severe COPD. The investigators aim to demonstrate this regardless of concomitant medication use, including inhaled corticosteroids. Additionally, the investigators hope to provide a mechanistic pathway by which these effects occur.
Title: Duplication in Chitotriosidase (CHIT1) Gene and the Risk for Aspergillus Lung Disease in CF Patients. Aim: To evaluate the link between CHIT1 duplication in CF patients and the predisposition to ABPA or persistent Aspergillus infection. Patients: 40 CF patients. Design: Observational, single visit. Methods: All patients will be assessed for pulmonary function tests (PFT), sputum cultures, and blood tests for: CHIT1 duplication, immunoglobulin E (IgE) and Eosinophils levels. Part of the patients will be assessed for RAST, skin prick test. Primary outcome measure is the difference in CHIT1 genotyping between the groups.
The purpose of this Phase III study is to evaluate the long-term safety and tolerability of two fixed-dose combinations of inhaled aclidinium bromide/formoterol fumarate, aclidinium bromide, formoterol fumarate and placebo in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD). Long-term efficacy, pharmacoeconomic and health-related quality of life assessments will also be evaluated. This extension study will include a 28 week treatment period, followed by a four week follow up visit. All patients will remain in the same treatment group as for the lead-in study and continue on one of the four treatment arms or placebo.
