Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The the aim of this study is to determine the benefits of Telehealth monitoring in the management of patients with chronic obstructive pulmonary disease.

This study will assess the safety and pharmacokinetics of inhaled GSK573719 and GSK573719/vilanterol combination in healthy subjects and in subjects with severe renal impairment. The results of the study will provide guidance on the use of this product in subjects with severe renal impairment.

Non-invasive ventilation (NIV) in severe hypercapnic Chronic Obstructive Pulmonary Diseases (COPD) may be associated - during sleep - with recurrent episodes of patient ventilatory asynchrony, which in turn may affect quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.Polysomnography (PSG) under NIV is necessary to detect these events. Adjusting ventilator settings according to respiratory events detected by PSG with NIV may improve quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.

The purpose of this study is to find out more about the effects of chronic obstructive pulmonary disease (COPD) on the function of blood vessels, the heart, and muscle at rest and during exercise.

The primary purpose of this study is to compare and assess the immediate and long-term effects on pulmonary rehabilitation training with the usage of HFNC or conventional oxygen therapy device. The hypotheses was, with high flow nasal cannula usage while exercising, the physiological outcome measurements would be better than conventional oxygen therapy device. Also, the usage of HFNC can immediately increase patient's exercising endurance and decrease dyspnea caused by exercising.

Determination of the acute pulmonary toxicities of e-cigarettes in young adults is of major public health importance, as e-cigarette vapor contains established toxicants that as hypothesized cause acute damage to the airways and the pulmonary microvasculature that may promote the development of CLD, for which there remain few effective therapies. The study therefore propose a pilot study using a randomized crossover design in ten healthy young adults to test the acute effects of a standardized e-cigarette exposure on two sensitive, safe, non-invasive imaging measures: (1) ventilation defects on hyperpolarized helium-enhanced magnetic resonance imaging, and (2) pulmonary microvascular blood flow on gadolinium-enhanced pulmonary magnetic resonance angiography.

The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 3 other provinces: British Columbia (BC); Manitoba (MB); and Nova Scotia (NS). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.

This study will develop and experimentally test the efficiency of a neurofeedback training protocol vs. varenicline use for smoking cessation.

The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory failure is supportive and involves inhalation bronchodilators along with systemic steroids. In few cases the management of acute respiratory failure requires positive pressure ventilation (non-invasive or invasive). The use of NIV in acute exacerbation of COPD has resulted in significant reduction in morbidity and mortality. Although pressure support ventilation (PSV) allows the patient to influence the breathing pattern, ventilator-cycling criteria may worsen the patient-ventilator interaction, and severe asynchronies occur in up to 43% of patients undergoing NIV for ARF. Adaptive support ventilation (ASV) is a newer mode of ventilation that incorporates feedback mechanisms and thus provides a stable minute ventilation. We hypothesize that the use of ASV as a mode during ventilation using NIV in patients with acute exacerbation of COPD may result in reducing the duration of ventilatory support, need for intubation, and duration of intensive care unit (ICU) and hospital length of stay, when compared with PSV mode of NIV ventilation.

This study aimed to evaluate the acute effect of PLB technique on diaphragmatic mobility, the kinematics of the thoracoabdominal complex analysis of lung volumes and exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD). This is a study randomized cross-over clinical trial and blind, in subjects with Chronic Obstructive Pulmonary Disease (COPD) according to criteria of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) (FEV1 / FVC <0.7 and FEV1 <80% predicted) selected at the Clinical Hospital of the Federal University of Pernambuco (UFPE) and Otavio de Freitas General Hospital (HGOF). The investigators recruited 13 patients COPD (according to previous sample calculation) aged between 40 and 80 years, of both sexes. The first day was held evaluation of lung function, respiratory muscle strength, body composition, dyspnea index and functional capacity. On the second day was held evaluation of thoracoabdominal complex kinematics by plethysmography Optoelectronics (OEP) with Quiet Breathing (QB) or pursed-lips breathing (PLB). Lung volumes with 2 minutes with QB and 6 minutes PLB or only 6 minutes by QB as randomization were observed. Before and after performing the requested breathing pattern diaphragmatic mobility was observed by Ultrasonography (US) and requested the patient an Inspiratory Capacity maneuver (IC). The evaluator who performed the ultrasound was blinded as to the beginning of the breathing pattern of order performed by the patient.
