Filter by:The overall objective of this study is to evaluate a collaborative self-management intervention in patients with moderate to severe COPD in a primary care population. To achieve this objective the investigators developed a diagnostic and treatment pathway for the management of COPD in primary care that is based on national guidelines and focused on patient self-management.
Early changes associated with the development of smoking-induced diseases, e.g., COPD and lung cancer (the two commonest causes of death in U.S.) are often characterized by abnormal airway epithelial differentiation. Airway basal cells (BC) are stem/progenitor cells necessary for generation of differentiated airway epithelium. Based on our preliminary observations on SAE BC cells and FGFR2 signaling, we hypothesized that suppression of FGFR2 signaling in the SAE BC stem/progenitor cells by cigarette smoking renders these cells less potent in generating and maintaining normally differentiated SAE, shifting these cells towards a COPD associated phenotype. To test this, SAE basal cells will be isolated from cultured cells obtained through bronchoscopic brushings and analyzed through in vitro assays for their stem/progenitor capacities.
The primary objective of this study is to assess tolerability and effect of HS (hypertonic saline) delivered with the tPAD (transnasal Pulmonary Aerosol Delivery) device on mucociliary clearance (MCC) in chronic obstructive pulmonary disease/chronic bronchitis (COPD/CB) subjects. The investigators hypothesize that HS delivery via tPAD will be safe and and while, and will improve MCC.
The aim of this study was to elucidate the accuracy and inter-rater agreement of diagnosis of nontuberculous mycobacterial lung disease based on chest computed tomography findings.
A single center case-control study with 100 COPD patients will be organized to compare patients with and without bronchiectasis with regard to the presence of Aspergillus in sputum samples, Aspergillus sensitization and vitamin D. Induced sputum samples will be optimized for culture, Aspergillus galatomannan analysis and RT-PCR. This study is part of a larger project in which we assume that chronic respiratory infection by Aspergillus fumigatus and the accompanying immune response play an important role in the development of bronchiectasis in COPD. We suspect that this mechanism is controlled by vitamin D and it fails by suppression of the vitamin D receptor by Aspergillus fumigatus. The present study is designed by the Laboratory of pneumology and will be conducted in collaboration with the Laboratory of clinical bacteriology and mycology of the Catholic University of Leuven.
The aim of this study was to compare the tiotropium Respimat Soft Mist Inhaler and the HandiHaler in terms of their effects on sleeping oxygen saturation (SaO2) and sleep quality in patients with COPD.
Primary objective: The aim of this study is to determine the efficacy and safety of five days of oral corticosteroids (40 mg / day) for the treatment of acute exacerbations of COPD (AECOPD) in outpatients.
The purpose of this randomized controlled trial was to evaluate the effects of a respiratory rehabilitation exercise training package on dyspnea, cough, exercise tolerance, and sputum expectoration of hospitalized elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Using purposive sampling, 61 participants were recruited and randomly assigned to either the experimental group (n = 30) or the control group (n = 31). The experimental group participants received the respiratory rehabilitation exercise training twice a day and 10-30 minutes per session for four days. The control group participants received usual care and health education. Data were collected at baseline and at the end of the four-day intervention.
Objective The Ultrasonic Cardiac Output Monitor (USCOM) is a non-invasive, quantitative method for measuring and monitoring cardiovascular haemodynamic parameters in patients. The aims of this study are: 1. To investigate whether there is any correlation between haemodynamic parameters and COPD severity. 2. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 6-month, 1-year, 3-year and 5-year readmission. 3. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 6-month, 1-year, 3-year and 5-year all-cause mortality. Design, Setting and Subjects This prospective observational study will be conducted in the Prince of Wales Hospital in Hong Kong. Interventions Haemodynamic measurements made using the USCOM, and spirometry, will be performed as appropriate on subjects in respiratory clinic, the emergency department, medical wards and on ICU. In order to assess inter-observer variability, a second, blinded operator will repeated 15% of scans.
