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.
Preliminary studies have shown that NPPV can avoid tracheal intubation in 40% to 60% patients who have severe exacerbation of COPD. Recently, large-scale comparative effectiveness research (CER) also found that compared with invasive ventilation, NPPV can reduce mortality rates. But there's no high-quality clinical studies which can confirm this. Therefore, investigators believe that NPPV can avoid intubation in patients with severe exacerbation of COPD in ICU with perfect monitoring conditions and reasonable human resource allocation, in order to reduce IMV-related complications and improve patients' outcomes.
A clinical, prospective, randomized controlled trial to determine the effect of prescribing oxygen in a group of COPD (chronic pulmonary disease) patients with PaO2 (arterial oxygen tension) ≥50 and ≤55 mmHg who do not have erythrocytosis or pulmonary hypertension on echocardiogram (which are considered manifestations of chronic hypoxia)
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.
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.
For moderate AECOPD(pH<7.35), several guidelines have strongly recommended NPPV as standard therapy, which can reduce the rate of intubation and mortality. A few previous studies have shown that HFNC can efficiently improve alveoli ventilation and breathing pattern in some severe AECOPD patients. Therefore, we hypothesize that HFNC is not inferior to NPPV for preventing endotracheal intubation in moderate AECOPD patients. To assess this hypothesis, we performed a multicenter, randomized, noninferiority trial of HFNV vs NPPV in moderate AECOPD patients.
The principal objective of the study is to measure parameters of inflammation, oxidative stress, and vascular, respiratory, and peripheral muscle function parameters, and identify parameters indicative of evolving cardiovascular risk (CVR) in COPD patients, using multivariate analysis.
Asthma is a chronic inflammatory disease of the Airways of recurring character. The obstruction to the airflow carries the short-and long-term consequences that require prophylactic interventions and in emergency many times. The children due to immaturity of the respiratory system associated with the use of steroids suffer structural consequences, as for example, the physical deconditioning that intensifies the symptoms of the disease and affects negatively on the quality of life. Therefore, to set up a physical training program suitable for the paediatric population, using resources to increase adherence to the regular practice of exercises, can be the difference for the reduction of the number of exacerbations, the sensation of Dyspnea and the doses of medication, positively impacting the clinical picture of child asthmatic. The investigators conducted a randomized, blinded in order to evaluate the effects of training with active video game associated with resisted exercise the exercise in inflammatory and functional outcomes resisted in asthmatic children.
This is a multicenter, single-arm trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD).
