Filter by:This is a crossover Study to investigate the effect of Formoterol versus Salmeterol on small airways physiological parameters in COPD patients.
To study in clinically stable Chronic Obstructive Pulmonary Disease (COPD) patients with muscle atrophy: 1. The short-term effects of 4 months exercise training including nutritional supplementation versus exercise training alone on physical functioning (skeletal muscle strength and exercise capacity) and body composition. 2. The long-term effects of 4 months of exercise training and nutritional supplementation followed by 8 months of nutritional counseling (with supplementation on advice) and feedback on physical activity level versus 4 months of exercise training and 8 months with feedback on physical activity level alone on physical functioning, body composition and cardiometabolic risk profile; 3. The cost-effectiveness of exercise rehabilitation and nutritional intervention versus exercise rehabilitation alone.
The purpose of this study is to evaluate the 24-hour spirometry effect (FEV1) of Fluticasone Furoate/Vilanterol 100/25mcg once daily compared with Salmeterol/Fluticasone Propionate 50/500mcg twice daily over a 12-week treatmen period in subjects with COPD.
In 2005, more then one-third of Canadians were burdened with one or more chronic diseases. Patients with one chronic disease often have, or are at risk for, another chronic disease. This group of complex patients represents a substantial challenge to healthcare resources. For patients in rural communities, the opportunity to attend ambulatory care clinics is not always an option. Additionally, the opportunity for rural patients to receive quality care close to, or within their homes, is of great benefit as it reduces the need for extensive travel and the potential burden of clinical visits. The use of telehealth has been identified as an effective modality for chronic disease management and is actively promoted by national organizations as having great promise for health service delivery in rural areas. The Internet as a mode for healthcare delivery has numerous advantages: 1. it is ubiquitous with increasing access in all age groups, 2. it is inexpensive, 3. it facilitates both patient data transfer and patient feedback, thereby supporting patient self-management, 4. it is scalable to large patient volumes, 5. it delivers health care directly to the patient and 6. it requires minimal set-up for patients with current Internet access. The investigators propose to develop and evaluate a multi-chronic disease management program delivered through the Internet (with telephone supports) focused on high-impact chronic diseases targeted to patients in rural communities. This study will consist of a single-blinded randomized controlled trial to investigate the efficacy of the iCDM in 318 patients with two or more of the target chronic diseases living in rural areas. Within this Aim, the investigators will be able to address the following research questions: Q1. What is the effect of iCDM on healthcare utilization and patient self-management outcomes? Q2. What is the long-term compliance to the iCDM? Q3. What is the level of patient and provider satisfaction?
The purpose of this research study is to test a program developed to help patients with chronic heart or lung problems take care of themselves and cope with their illness or limitations.
The purpose of this study is to observe how the inflammatory pathways differ in subjects with chronic obstructive pulmonary disease (COPD) during an acute exacerbation of COPD (AECOPD).
The objective of this study was to examine COPD-related outcomes for patients with comorbid depression/anxiety who are on combination fluticasone propionate/salmeterol xinafoate compared to those receiving anticholinergics. The prevalence of comorbid depression/anxiety in patients with chronic obstructive pulmonary disease (COPD) is estimated to be high and range from 10-40%, given that the risk of depression/anxiety symptoms is almost 3 times higher in patients with versus without COPD. Additionally, patients with comorbid COPD and depression/anxiety have higher COPD-related healthcare utilization and costs compared to those without depression/anxiety. Therapy with maintenance medications for COPD has been recommended to prevent future adverse COPD outcomes, but the impact of initiating these interventions has not yet been evaluated in a higher-risk population with comorbid COPD-depression/anxiety. The present study compares the risk of COPD exacerbations and COPD-related costs in patients initiating maintenance medications for treatment of COPD in a comorbid COPD/depression-anxiety population. Maintenance medications include inhaled corticosteroid (ICS), long-acting beta agonist (LABA), combination drug product of ICS+LABA, and anti-cholinergics (AC) including tiotropium (TIO) and ipratropium or combination ipratropium-albuterol (collectively abbreviated as IPR).
The purpose of the study is to investigate the effect of fluticasone furoate/vilanterol Inhalation Powder on arterial stiffness compared with placebo and vilanterol over a 24-week treatment period in subjects with COPD and aortic pulse wave velocity of 11.0 m/s or above.
An estimated three million people are affected by chronic obstructive pulmonary disease (COPD) in the UK, giving it a prevalence of 1.5% of the population in 2007/08. COPD accounts for approximately 30,000 deaths each year in the UK and is an important co-morbidity in those dying from other smoking related diseases, most commonly ischaemic heart disease and lung cancer. The National COPD audit showed a very high level of co-morbidity, the association with cardiovascular disease being particularly strong with 51% of patients with cardiovascular disease having been admitted for COPD within the preceding 24 months. Patients with COPD are at increased risk of myocardial infarction compared to the general population. Although this increase in cardiovascular risk exists, it is not clear is whether survival after myocardial infarction is different in patients with and without COPD and what factors contribute to this survival difference. Differences in survival may arise due to differences in prescribing certain drugs such as beta-blockers, differences in prevalence of risk factors (e.g. current smoking status) or increased COPD events such as exacerbations which themselves are associated with increased mortality. The investigators primary aim is to investigate whether survival after first myocardial infarction is shorter in patients with COPD than those without COPD and to establish reasons for these differences in survival.
This was a retrospective cross-sectional database study using administrative data (study period: 1/1/2003 through 7/31/2008). Managed care enrollees (aged >40 years) having at least one Hospitalization with primary or secondary diagnosis of COPD (ICD code 491.xx, 492.xx and 496.xx) or at least one Emergency Room (ER) visit with primary diagnosis of COPD (index event) during the study period was the target population. All subjects were required to have one year of pre-index period baseline data. COPD events of interest were ER, Hospital and physician visits followed by oral corticosteroids (OCS) or antibiotics (Ab) within 7 days. Other censoring events were treatment switch; loss of enrollment; >60-day gap between medication fills; or end of study period. This study is a non descriptive hypothesis testing study. Key study hypotheses are listed below. Specifically the study hypotheses for the primary outcome being tested were: Ho: There is no difference in risk of COPD-related hospitalization between FSC and OMT Ha: There is a difference in risk of COPD-related hospitalization between FSC and OMT Hypothesis for the key secondary outcome of COPD-related costs that was tested was: Ho: There is no difference in COPD-related costs between FSC and OMT Ha: There is a difference in COPD-related costs between FSC and OMT
