Filter by:The purpose is to evaluate exercise performance in patients with Chronic Obstructive Pulmonary Disease (COPD) after supplementing with higher doses of dietary NO3-, compared to previous studies, as beetroot juice for seven days. The secondary purpose is to evaluate oxygen consumption of submaximal cycling, amendments in blood pressure, and physical activity level.
Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory disease of the airways, associated with poor health status, functional disability, significant morbidity, and increased risk of death. In Ontario, COPD is the leading cause of hospital admission and readmission, and costs the health system approximately 3 billion dollars annually. Individuals with COPD experience increased 'flare-up's' (acute exacerbations) as their disease worsens, characterized by periods of increased shortness of breath, cough, phlegm production, and weakness. Acute exacerbations of COPD (AECOPD) are most commonly caused by viral or bacterial infections, and often require patients to seek attention at the emergency room or hospital for treatment. Current treatments to prevent COPD exacerbations are only modestly effective. New therapies are needed to improve the quality of life and clinical outcomes for individuals living with COPD. Previous research at our center has shown a favourable effect of an antibody treatment (immunoglobulin) on the frequency of AECOPD, doctor visits, treatments, and hospitalizations for COPD patients. However, rigorous studies with more patients are required to confirm this effect. The investigators propose a clinical trial to evaluate immunoglobulin treatment in outpatients with frequent exacerbations. In this study the investigators will determine if immunoglobulin treatment is feasible, safe, tolerable, and potentially effective in reducing the frequency of acute exacerbations. If this study is feasible and potentially effective, it will inform larger studies to confirm the therapeutic effect of immunoglobulin treatment, and would be a major advance in care of COPD.
Acute exacerbation of COPD (AECOPD) worsen prognosis and quality of life of COPD patients. Telemonitoring could be a useful tool for early identification of AECOPD. Parameters that have to be monitored are not well defined. Patients with severe COPD may use home non-invasive ventilation (NIV). NIV have built-in software which are recording the breathing pattern of patients when used. The aim of this study is to identify ventilation parameters that are modified at the early stage of an AECOPD.
Inspiratory muscle training（IMT）was an rehabilitation therapy for stable patients with chronic obstructive pulmonary disease(COPD). However, its therapeutic effect remains undefined due to unclear of diaphragmatic mobilization during IMT. Diaphragmatic mobilization represented by transdiaphragmatic pressure（Pdi）and neural respiratory drive expressed as corrective root-mean-square(RMS) of diaphragmatic electromyogram(EMGdi) provide vital information to select the proper IMT device and loads in COPD, therefore make curative effect of IMT clarity. Pdi and RMS of diaphragmatic electromyogram (RMSdi%) was respectively measured and compared during inspiratory resistive training and threshold load training in stable patients of COPD.
The aim of this study is to determine whether common CYP1A2 gene polymorphisms effect metabolism of theophylline in Han and Uygur Patients with chronic obstructive pulmonary disease patients.
Rationale: In Canada, home care clients are a large and expanding subgroup of medically complex older adults with relatively poor access to effective chronic disease management. They have double the emergency department utilization rate compared to nursing home residents or other older populations. The investigators previously published a case-finding tool (the Detection of Indicators and Vulnerabilities for Emergency Room Trips (DIVERT) Scale) that has been recommended for chronic disease management case-finding in home care. The investigators recently conducted a pilot trial in Niagara, Canada, of a targeted, person-centered model of supportive cardio-respiratory disease management. Objectives: The investigators will evaluate a cardio-respiratory disease management model in home care to manage symptoms and avoid emergency department use. A pan-Canadian, pragmatic cluster-randomized trial will be conducted by a collaboration of trial investigators and public home care providers (i.e., health regions). The main objective is to evaluate the effectiveness and preliminary cost-effectiveness of a targeted, person-centered cardio-respiratory management model. The main question is: P: Among home care clients experiencing cardio-respiratory symptoms (objectively targeted using the DIVERT Scale), I: can a guideline-based, feasible, multi-component/complex, cardio-respiratory management model, C: compared to regular care, O: reduce cardio-respiratory symptoms, reduce/postpone unplanned emergency department (ED) visits, reduce unplanned hospital use, improve patient activation, or improve health-related quality of life for clients, T: over a 6-month follow-up period from baseline?
The purpose of this study is to validate the diagnostic accuracy of a novel host-response based diagnostic tool for differentiating between bacterial and viral etiologies in adult patients aged 18 years and older with clinical suspicion of lower respiratory tract infections (LRTI)
The aim of this study is to test whether aspirin improves endothelial function in alpha-1 antitrypsin deficiency-associated lung disease, measured by pulmonary microvascular blood flow on magnetic resonance imaging (MRI) and with apoptotic endothelial microparticles.
Pseudomonas aeruginosa (PA ) is associated with chronic lung infections in patients with chronic obstructive pulmonary disease (COPD). Commensal flora (microbiota) in lung was recently described using high-throughput sequencing techniques (NGS). PA strains isolated during lung infection episodes of severe COPD patients often show resistance to antibiotics including imipenem that is mainly due to mutation in oprD. In collaboration with Harvard Medical School, the investigators have recently demonstrated that PA OprD mutant shows increased survival (fitness) and its virulence. This bacterium could be more likely to colonize. Colonization by PA OprD mutant could influence the pulmonary microbiota and may worsen disease evolution, particularly in terms of frequency of exacerbations. Our objective is to describe modification of pulmonary microbiota associated with PA colonization, including OprD PA mutant, in severe COPD patients. The investigators will correlate the microbiota modification to medical history. Stable severe COPD patients will be included. Three groups of patients will be sampled: 1) not PA colonized, 2) PA colonized and 3) PA OprD mutant colonized. Medical history will be recorded by the physician as usual and three samples will be performed: 1) sputum, 2) oral wash and 3) water used for oral wash. Regular bacterial culture will be performed and NGS will be performed also to characterize the microbiota.
supplementation with L-carnitine that is available both as an FDA-approved therapy for primary carnitine deficiency, as well as widely available as an over-the-counter ergogenic aid will improve wellbeing and function measured by questionnaires in patient with chronic obstructive pulmonary disease (COPD). based on our review of literature that addition of health coaching (HC) to L-carnitine will yield greater gains.
