Filter by:People with Chronic Obstructive Pulmonary Disease (COPD) often have periods during the year when their symptoms become worse. These are often due to an infection and are called "exacerbations" by doctors. Exacerbations are more common in the winter and also seem to be related to particular types of weather. As well as forecasting the weather the UK Met Office has developed a system to try to predict when exacerbations are likely to occur. The main purpose of this research study is to find out whether the Met Office forecasting service can predict when exacerbations are more likely to occur and whether the advice given during the predicted higher risk periods leads to fewer patients having an exacerbation or if it reduces the impact of the exacerbation. The study will also assess if there is a link between viral or bacterial infection and breathing problems that occur during the study period. The study will also collect information about possible causes of the breathing problems and what happens to the person afterwards. The results of this study will help us learn more about breathing problems which may lead to new research studies that would aim to improve the care of people with COPD.
The prevalence of chronic obstructive pulmonary disease (COPD) in patients with cardiovascular disease (CVD) is unknown, and whether or not COPD is adequately diagnosed and treated in these patients has not been investigated before. We hypothesized that the prevalence of COPD would be significantly higher (30%) in patients with CVD than in the general population. Besides, we anticipated that COPD, a potentially treatable CV risk factor, would be undiagnosed in more than 80% of CVD patients.
The Patient-Reported Outcomes Measurement Information System (PROMIS) is an NIH Roadmap initiative to develop a computerized system measuring patient-reported outcomes in respondents with a wide range of chronic diseases and demographic characteristics. In the first four years of its existence, the PROMIS network developed item banks for measuring patient-reported outcomes in the areas of pain, fatigue, emotional distress, physical function, and social functioning. During the item banking process, the PROMIS network conducted focus groups, individual cognitive interviews, and lexile (reading level) analyses to refine the meaning, clarity, and literacy demands of all items. The item banks were administered to over 20,000 respondents and calibrated using models based on item response theory (IRT). Using these IRT calibrations, computerized adaptive test (CAT) algorithms were developed and implemented. The network has designed a series of studies using clinical populations to evaluate the item attributes, examine their utility as CATs, and validate the item banks. More information on the PROMIS network can be found at www.nihpromis.org.
The purpose of this study is to determine whether discussions of life story, forgiveness, and future goals improve quality of life for patients with serious illness.

More information on the PROMIS network can be found at www.nihpromis.org. This study is designed to examine how differences in modes of data capture affect psychometric properties and score differences and to evaluate the consistency of these results across three PROMIS health domains: emotional distress-depression, fatigue, and physical function. Four modes of administration will be compared: interactive voice response (IVR) technology, paper and pencil questionnaire, personal computer, and personal digital assistant (PDA). A total of 800 patients will be enrolled from three diagnostic groups: chronic obstructive pulmonary disease (COPD), depression, and rheumatoid arthritis. The study will test for equivalence across modes of administration, with the hypothesis that there are no mode effects; if mode effects are found, their magnitude across modes will be estimated. This network project will result in an improved understanding of the effect of assessment mode on patient-reported outcome (PRO) data. Guidance from this project can help in planning future PROMIS activities beyond the present PROMIS program.
This is a randomized, double-blinded, Phase I dose escalation-deescalation protocol (DEP) of cyclosporine inhalation solution in patients with Gold Stage III chronic obstructive pulmonary disease. The purpose of the study is to evaluate the safety and effectiveness of aerosolized Cyclosporine in treating COPD. The specific aims of the study are: 1. To identify the short term (28 day) safety profile of CyIS immunotherapy in severe COPD (GOLD III) patients with particular attention to airway reactivity and infection risk. 2. To identify the pharmacokinetic-pharmacodynamic relationship of CyIS using peripheral blood markers of an adaptive immune response as endpoints in subjects with severe COPD (GOLD III) treated short-term. Subjects between 45 and 70 years of age with a confirmed diagnosis of COPD, Gold Stage III, and meet all the study requirements, will be enrolled in this study. A total of 24 subjects of either sex will be enrolled in this study. A total of 4 subject cohorts (n=6) will participate in the protocol.
The purpose of this study is to characterize the dose-response profile of peak and trough FEV1 after single dose administrations of carmoterol in patients with COPD.
The purpose of this study is to evaluate the effect of single doses of therapeutic and supratherapeutic doses of inhaled CHF 4226 pMDI on ventricular repolarization in healthy subjects compared with placebo.
The purpose of this study is to evaluate the systemic exposure and pharmacodynamics of two doses of nebulized fluticasone/formoterol combination as compared to the monocomponents.
The overall purpose of PA-SCOPE is to determine why black and rural residents of Pennsylvania might be at higher risk for deadly, debilitating, and costly hospitalizations for chronic obstructive pulmonary disease (COPD)— and then to show that repeat acute exacerbations in high-risk patients can be reduced with one simple intervention. We believe that 1) COPD patients who are black or who live in rural areas of Pennsylvania are at higher risk of acute exacerbations requiring hospitalization and 2) this elevated risk can be reduced with one simple intervention: access to a 1-800 Temple Call Center where patients can get immediate customized advice on managing COPD exacerbations in their early stages. We will test these beliefs in PA-SCOPE. The collaborators with Temple University Hospital on the PA-SCOPE project are Lancaster General Hospital, Western Pennsylvania Hospital, and the Philadelphia College of Osteopathic Medicine.
