Filter by:The purpose of this study is to assess whether 6% hypertonic saline (HS) is a safe and effective preventive therapy in newborns and infants with cystic fibrosis (CF).
Left ventricular failure (LVF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis . The investigators expect that Valsalva Maneuver (VM) could be useful in this issue.
The study seeks to characterize data obtained from patients with a variety of lung diseases using ultrasound Doppler signals obtained from lung tissue. A standard ultrasound device in a Doppler mode is placed on the chest wall and the unique software the investigators have developed analyzes the signals reflected from within the lung. On the basis of of pilot studies performed previously the investigators expect to receive different signals from different diseases that will enable diagnosis of different lung diseases.
The purpose of this study is to elucidate phenotypic, clinical, and genetic characteristics of Korean Nontuberculosis Mycobacteria (NTM) patients.
Reports suggest that the Medicaid population includes a higher percentage of smokers than the general population. A high prevalence of smokers in a population is likely to lead to a higher burden of chronic obstructive pulmonary disease (COPD). Few studies have evaluated the economic burden of COPD in a Medicaid population. The objective of this observational, retrospective cohort study is to estimate the economic burden of COPD in subjects with a COPD diagnosis who are enrolled in Medicaid and are receiving maintenance treatment covered by Medicaid. Specifically, the null hypothesis for the primary outcome measure is that no difference is observed in all-cause costs between subjects with and without COPD. The test hypothesis is that there is a difference in all-cause costs between subjects with and without COPD. Secondary outcomes to be evaluated include all-cause resource use and COPD-related costs for the COPD cohort. The study uses a medical and pharmacy administrative claims database called MarketScan Medicaid Database that contains the medical, surgical, and prescription drug experience of nearly 7 million Medicaid recipients. This analysis will use data from 8 states.
The purpose of this research study is to learn about the safety of transplanting lungs obtained from non-heart-beating donors (NHBDs) that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo perfusion and ventilation is to learn how well the lungs work, and whether they are likely safe to transplant.
The purpose of this study is to investigate whether patients with a preoperative reduced pulmonary function have a better preserved oxygenation capacity after open heart surgery, using either pulmonary perfusion or pulmoplegia compared with TAVI and the control-group with standard ECC (Extra Corporal Circulation).
This study compared the efficacy and safety of NVA237 with tiotropium in patients with moderate to severe COPD. Tiotropium belongs to the same drug class as NVA237.
This study will look at the safety, improving symptoms and decreasing the length of stay of patients admitted to the hospital with COPD.
The purpose of this study is to evaluate the performance of AVAPS AE therapy in COPD patients during nocturnal ventilation.
