Filter by:The purpose of this study is to evaluate the effects of temazepam during sleep and in daytime on dyspnea, gas exchange and sleep quality in patients with chronic obstructive pulmonary disease. The study hypothesis is that temazepam does not produce any adverse respiratory effects during sleep in patients with COPD. In contrast, it may result in an beneficiary effect because it positively affects the sleep quality and sleep structure which may result in more alertness and less daytime sleepiness and less dyspnea during the day.
The first objective of this study is to determine if increased expression of one or more members of the toll-like receptor (TLR) family of receptors that are found on inflammatory cells (present in the airway) precede development of chronic lung disease (CLD) of prematurity. The study will also determine if there is a significant correlation between TLRs and the severity of CLD. The second objective of this study is to determine the impact of c-administration of inhaled nitric oxide (INO) on TLR expression in infants at risk of developing CLD or with early CLD.
Dyspnea (shortness of breath) is a complex experience that includes interpretation of physical impairments and associated distress to the person. The role of mind-body interactions in the experience of the symptom of dyspnea suggests that complementary and alternative medicine (CAM) therapies may be effective in abating dyspnea and improving patients' health-related quality of life. CAM strategies work in a number of ways that are directly applicable to dyspnea, such as decreasing the stress response, inducing relaxation, and facilitating a less distressful interpreted experience of physical disorders. We have combined a number of established CAM approaches aimed at breath-centered mindfulness and relaxation into an single therapy, mind-body breathing therapy (MBBT). The purpose of this study is to test the efficacy of MBBT in improving dyspnea and health-related quality of life for patients with emphysema (chronic obstructive pulmonary disease).
The aim of the study is to compare the effect of roflumilast on lung function in patients with COPD. Roflumilast will be administered orally once daily in the morning at one dose level. The study duration consists of a baseline period (4 weeks) and a treatment period (12 weeks). The study will provide further data on safety and tolerability of roflumilast.
The aim of the study is to investigate the effect of roflumilast (APTA-2217) on lung function in patients with chronic obstructive pulmonary disease (COPD). Roflumilast will be administered orally once daily. The study duration consists of a baseline period (4 weeks) and a treatment period (24 weeks). The study will provide further data on safety, tolerability, and effectiveness of roflumilast.
The purpose of this study is to test two asthma management programs: (a) a school-based curriculum to empower middle school students to manage their asthma and (b) a parent training curriculum to teach childrearing skills that support the youths' growing autonomy and need to self-manage their disease.
The purpose of this study is to determine the diagnostic accuracy of gadolinium-enhanced magnetic resonance angiography (Gd-MRA) of the pulmonary arteries in combination with magnetic resonance venography (MRV) of the veins of the thighs in patients with clinically suspected acute pulmonary embolism (PE).
The purpose of this study is to examine the effectiveness of approaches to correct for the effects of population stratification on case-control genetic association studies.
To examine air pollution, inflammation and new onset asthma in a large cohort of children in southern California.
The primary objective of this study is to estimate the comparative bronchodilator effect size and variability for tiotropium (Spiriva, 18 µg q.d.) with the free combination of salmeterol (Serevent, 50 µg b.i.d.) and fluticasone (Flixotide, 250 µg b.i.d.) in COPD patients. International COPD guidelines preserve milder stages of the disease (GOLD stage I and IIa) to bronchodilators and recommend the addition of inhaled corticosteroids only in those patients who have a documented spirometric response to inhaled corticosteroids and in patients with a post-bronchodilator FEV1 of less than 50% predicted, who suffer from frequent exacerbations requiring oral courses of corticosteroids. Recently published reports indicate that additional bronchodilator efficacy may be achieved when a long-acting beta agonist is combined with an inhaled corticosteroid. Steady state bronchodilation was achieved within one week with the drug combination. However, results of these studies are not consistent, and since the inclusion criteria employed were different from those utilised in the previously conducted tiotropium studies, it is difficult to generalise the observed effects to the general COPD population. In addition, no comparative data is available on the average response over the 12 daytime hours when COPD patients are active and in most need of bronchodilation. 12 hours corresponds to the dosing intervals for both salmeterol and fluticasone.
