Filter by:Stage 1 of the study is designed to provide data about the risk-benefit of 4 dose regimens of indacaterol (75, 150, 300 & 600 µg o.d.) in order to select two doses to carry forward into study Stage 2. Study Stage 2 will provide pivotal confirmation of efficacy, safety, and tolerability of the selected indacaterol doses in patients with COPD
The purpose of this study is to compare the efficacy of Formoterol Fumarate Inhalation Solution (FFIS) 20 mcg BID to Combivent® Inhalation Aerosol [2 inhalations from metered dose inhaler (MDI)of 18 mcg ipratropium bromide and 103 mcg albuterol sulfate QID], and to Compare the preference/compliance of BID nebulization to QID use of MDI
Chronic obstructive pulmonary disease, including emphysema and chronic bronchitis, is the fourth most common cause of death and the second leading cause of disability in the United States. COPD is estimated to be responsible for more than 13.4 million physician visits and 13% of hospitalizations nationally. These hospitalizations are usually caused by acute exacerbations characterized by an increase in symptoms including dyspnea or shortness of breath (SOB), cough, wheezing, and sputum production. The significant disability for people with COPD is primarily due to the symptom of dyspnea (shortness of breath) that affects an individual's quality of life more than does the physiological impairment. Despite optimal medical and pharmacological therapy, most people with COPD continue to suffer from chronic and progressive dyspnea and other symptoms of cough and fatigue. We have previously shown that an individualized face-to-face dyspnea self-management program was effective in improving dyspnea with activities of daily living (ADL), physical functioning, and self-efficacy for managing dyspnea. Using an experimental longitudinal design, the i-DSMP will be compared to the Face-to-Face Dyspnea Self-Management Program (f-DSMP) and to an Attention Control (AC) intervention
Non-invasive positive pressure ventilation (NIV) refers to the provision of mechanical ventilation without an artificial airway (for example, an endotracheal tube). Over the past decade, evidence from randomized control trials has accumulated to demonstrate effectiveness of the technique in avoiding intubation, reducing complications associated with intubation, shortening ICU and hospital lengths of stay, and reducing mortality rates in selected patients with acute respiratory failure. However, NIV is still underutilized at many medical centers. The purposes of this project will be to acquire information related to NIV use, to identify reasons for underutilization, to implement interventions that encourage more appropriate use of NIV, and to evaluate the effectiveness of the interventions. Reliable information on NIV use as well as analysis of reasons for underutilization will provide insight into ways of enhancing NIV use. We will determine utilization rate, technology used, patient diagnoses, duration of ventilator use and hospital stay, and success rates as recorded on case report forms (CRFs). After completing the survey, we will provide an educational program to randomly selected institutions (one-half of the total) aimed at increasing the knowledge and skill of physicians, nurses, and therapists regarding use and implementation of NIV. Data will be gathered for a second round with the same data-gathering instruments used during
Endorphins are naturally occurring narcotic substances that are released when individuals perform exercise. The hypothesis of the study is that endorphins reduce the severity of breathlessness during exercise in patients with chronic obstructive pulmonary disease (COPD). The initial five visits include familiarization and validation of a computerized system for patients to report dyspnea and leg discomfort continuously during exercise testing. At Visits 6 and 7 blood is drawn to measure serum endorphin levels pre-exercise, end exercise, and 30 minutes after exercise. Normal saline or naloxone is given intravenously 5 minutes prior to exercise in a double-blinded design. The primary outcome is the slope of oxygen consumption - dyspnea.
The objective of this study is to assess the effects of using HRQL measures in the clinical care of pre- and post-lung transplant patients. The hypotheses are that the inclusion of HRQL measures, the Health Utilities Index System Mark 2(HUI2) and Mark 3 (HUI3), in routine clinical care of pre- and post-lung transplant patients, will: 1) improve patient-clinician communication;2) affect patient management; 3) improve patients' HRQL.
More than 5 years ago the DVT FREE Registry was conceived. Its database consists of 5,451 ultrasound-confirmed DVT patients from 183 institutions. This database is rich in information of critical importance to health care providers. The information contained within the database will be revisited to provide more detailed analyses which will be used for risk factor assessment and for decision-making regarding the implementation of VTE Prophylaxis.
To determine whether an average population of males and females who smoke 10 pack years or more of cigarettes in a primary care setting with chronic bronchitis has already developed significant changes on pulmonary function testing.
Lymphoid follicles, consisting of T-and B cells, are involved in the chronic inflammatory response in COPD. Foxp3 positive regulatory T cells (Tregs) are present in these follicles and may be involved in the suppression of this chronic inflammatory response. We hypothesise that a dysfunction of Tregs underlies the development of the inflammatory response in COPD. This could be either due to a decreased presence of Tregs in COPD, or to an altered function of Tregs possibly caused by a decreased HO-1 expression and/or an altered TGFβ regulation.
This study aimed to assess airway inflammation in patients during the course of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) by serial analyses of their exhaled breath condensates (EBC).
