Chiacchierini, Ph.D., Jonathan Goldin, M.D., Ph.D., and Geoffrey McLennan, M.D., Ph.D. For the VENT Study Research Group: A Randomized Study of Endobronchial Valves for Advanced Emphysema Emphysema is a leading cause of disability and death. However, concern concerning the risk of perioperative complications and death contributes to underutilization.5-10 Early uncontrolled trials using unidirectional valves placed in decided on lung airways to block regional inflation while allowing exhalation have reported improvements in lung function and symptoms with modest risk, including distal pneumothorax or pneumonia.5,6,9,11-13 In this randomized, prospective, multicenter study, known as the Endobronchial Valve for Emphysema Palliation Trial , we sought to look for the protection and efficacy of unilateral treatment with endobronchial valves, in comparison with standard health care, in improving coprimary outcome measures of expiratory flow and walk distance in sufferers with advanced emphysema.

White donors were significantly older during donation than were non-white donors in the analysis sample and nationally . All kidney donors underwent nephrectomy between 1987 and 2007, and the median time from donation to the ultimate end of observed insurance eligibility was 7.7 years. The linked donor sample was similar based on race and sex to all living kidney donors in the OPTN and to age-standardized estimates in the overall population in NHANES. Regularity and Variation of Medical Diagnoses At 5 years after donation, the estimated prevalence of diagnosed hypertension was 17.8 percent , and the estimated prevalence of drug-treated hypertension was 13.6 percent .
