Filter by:Inhaled nitric oxide in preterm babies with respiratory failure or ventilator dependence will: 1. decrease the incidence of Bronchopulmonary Dysplasia (BPD) or death 2. shorten the length of oxygen therapy and hospital stay ,reduce the cost of hospital stay without increasing adverse effect
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
To demonstrate the additional benefit of roflumilast when added on to fixed-dose combination (FDC) LABA/ICS in the reduction of exacerbations in subjects with severe to very severe COPD.
Heart failure with preserved ejection fraction (HFpEF) accounts for over 50% of heart failure cases in the United States, affecting a primarily elderly population. No treatment has been shown to affect mortality in HFpEF, which is more than 50% at five years a hospitalization. This project explores the underlying cardiovascular physiology of patients with HFpEF with the goal of identifying new therapeutic targets that would allow improved treatment of this devastating disease.
HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. The investigators will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.
Establishing new biochemical markers in the differential diagnostics and risk stratification in heterogeneous patient collectives is becoming more and more important. The markers should be objective, reliable, reproducible, quick and cost effective as well as specific and sensitive. Concerning the differential diagnostics of "dyspnea", NT-pro-BNP plays the most important role for the evaluation of a cardiac origin. However, a corresponding biochemical marker for pulmonary stress is lacking. The aim of the study at hand therefore was the evaluation of surfactant protein B in the differential diagnostics of pulmonary and cardiac diseases.
A study to determine the cardiovascular effects of PF00610335 in healthy volunteers.
Non invasive ventilation (NIV) usually presents air leaks that may determine the result of this treatment. The clinical usefulness of analyzing (and quantifying) these leaks during the adaptation period to NIV has not been evaluated in prospective clinical studies as a predictive data of treatment effectiveness. Our hypothesis is that air leaks are correlated to a successful adaptation to NIV. And air leak magnitude may predict early failures of this treatment. And also, as we do not know if air leaks change during the adaptation period to NIV, we do not know whether early detection of air leaks plays a role in the therapeutic outcome. Our objective is to evaluate the clinical usefulness of quantifying air leaks during the adaptation period to NIV as a predictor of effectiveness of this treatment. We also want to evaluate the correlation between air leaks and clinical-functional patients' profile, and the ventilatory parameters selected and to evaluate air leaks variability during the adaptation period to NIV. Method: We will determine the air leak magnitude in twenty patients during adaptation to NIV. We will use VPAP III ventilators (ResMed, Australia), commercial nasal masks (Mirage o Ultra Mirage) and VPAP III/ResLinkTM (ResMed, North Ryde, Australia), a device that includes a monitoring system coupled with the VPAP III ventilator. This device allows to record air leaks and other ventilation parameters. We will perform four VPAP III/ResLinkTM recordings in each patient (the last night in hospital during the adaptation period, the first night at home, and one and two months later, after the initiation of NIV treatment). We will also perform a complete pulmonary function test, quality-of-life questionnaire (SF36), and a tolerance to NIV questionnaire in all patients at the onset of NIV treatment and two months later. We will evaluate which patients will need to change treatment at the end of the adaptation period to NIV. We also will analyze and compare air leaks magnitude in each of the four recordings stated above.
The purpose of this study is to determine if a lower extremity strengthening program as part of pulmonary rehabilitation will improve quadriceps muscle strength, endurance and functional status as well as overall quality of life. Hypothesis: 1. Lower extremity resistance training as part of a pulmonary rehabilitation program will improve quadriceps strength, endurance and functional capacity. 2. Lower extremity resistance training as part of a pulmonary rehabilitation program will improve quality of life in patients awaiting lung transplant.
This study will compare the effects of exercise training and breathing retraining (using metronome tones) to exercise training only. Exercise training lasts 12 weeks.
