Active clinical trials for "Lung Diseases, Obstructive"

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.

Background: Commonly, patients with chronic obstructive pulmonary disease (COPD) present dyspnea, dynamic hyperinflation (DH) and important peripheral muscle deoxygenation when performing their activities of daily living (ADLs). The slow chest compression (SCC) technique is a physiotherapy strategy that could maybe reduce DH, dyspnea and peripheral muscle deoxygenation in patients with COPD. The aim of the study is to analyse the effects of SCC in DH, dyspnea and peripheral muscle deoxygenation induced by exercise tests. The secondary objective was to identify responders and non-responders to the technique. Design: Randomized cross-over study. Setting: The study will be conducted in an outpatient pulmonary rehabilitation program in Florianopolis, Brazil Subjects: Patients with COPD (GOLD 2-4). Interventions: Patients will randomly receive or not the SCC after six-minute step test (6MST-SCC and 6MST-NonSCC). Main measures: At baseline and 1 minute after the tests, the inspiratory capacity (IC) will be assessed by the slow vital capacity (SVC) maneuver. At baseline, immediately after, and 1 minute after the tests, the dyspnea score will be assessed. The physiological responses and the peripheral muscle deoxygenation will be assessed during the tests and 1 minute after them.

The investigators are carrying out a feasibility study to explore whether an app for physical activity in Chronic Obstructive Pulmonary Disease (COPD) is acceptable to people with the condition and to healthcare professionals who help patients manage the condition.

The purpose of this trial is to determine whether a minimal homebased psychoeducative intervention is effective in management of anxiety and dyspnea in patients with severe chronic obstructive pulmonary disease.

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.

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.

Patients who are hospitalized at select Carolinas Healthcare System (CHS) sites with Chronic Obstructive Pulmonary Disorder (COPD) acute exacerbation symptoms will be treated per the CHS COPD Clinical Pathway. Patient outcomes will be followed, including but not limited to readmission. Patients on the pathway will also have access to navigator services.

This randomized controlled trial (RCT) will examine a nurse case management model for patients suffering from chronic obstructive pulmonary disease (COPD) in a Danish municipality, and is performed in order to evaluate the use of case management as a tool in achieving integrated, quality and cost-effective care for this group of patients. The main objectives are to evaluate how case management influences on hospital admissions, mortality, quality of life and self care, as well as to compare costs and cost-effectiveness of case management vs. usual care.

A single dose study with the inhaled anti-inflammatory agent PF-03715455 to establish if it has anti-inflammatory activity following a challenge with LPS. Inhaled LPS invokes an acute inflammatory response in the lung which can be seen in induced sputum. PH-0797804 is an internal control for the study.
