BACKGROUND & AIMS The effect of hepatitis C viral (HCV) infection on patient and allograft survival after orthotopic liver transplantation is controversial. Hepatitis C recurrence after transplant is inevitable, but studies to date have not found a survival difference between recipients with and without HCV. METHODS Using data from the United Network for Organ Sharing, we performed a retrospe...

Physical exercise has been associated with neuroprotective effects in the nigrostriatal dopaminergic system. To examine the impact of physical activity on Parkinson's disease risk prospectively, we followed 43 368 individuals who provided extensive information on physical activity at baseline. We estimated hazard ratios with 95% confidence intervals using Cox proportional hazards regression. Du...

BACKGROUND AND PURPOSE Most strokes occur among people aged 65 years and older. The increasing proportion of persons who are in this age group underlines the importance for health-care providers to be aware of trends in poststroke survival. We investigated poststroke survival trends from 1985 to 1989 among Medicare beneficiaries. METHODS Medicare hospital claim records and enrollment data wer...

BACKGROUND AND PURPOSE The purpose of this study was to examine the association between binge drinking and risks of mortality due to all causes of death with a focus on cerebrovascular disease in Korean men and women. METHODS This study followed a cohort of 6291 residents in Kangwha County, aged > or =55 years in March 1985, for their cause-specific mortality for 20.8 years up to December 31,...

Background It has widely been proven that metabolic syndrome (MetS) increases the risk of ischemic heart disease (IHD). MetS is confirmed based upon insulin resistance (IR). Our aim of this study is to evaluate the role of MetS and IR in the prediction of IHD incidence. Methods A total of 404 non-diabetic participants who underwent 75 g oral glucose tolerance test (75 g OGTT) were enrolled fr...

Minimal residual disease prior to allogeneic hematopoietic cell transplantation has been associated with increased risk of relapse and death in patients with acute myeloid leukemia, but detection methodologies and results vary widely. We performed a systematic review and meta-analysis evaluating the prognostic role of minimal residual disease detected by polymerase chain reaction or multiparame...

BACKGROUND Blacks are thought to have a higher risk of venous thromboembolism (VTE) than whites. However, prior studies are limited to administrative databases that lack specific information on VTE risk factors or have limited geographic scope. METHODS AND RESULTS We ascertained VTE from 3 prospective studies: the Atherosclerosis Risk in Communities Study (ARIC), the Cardiovascular Health Stu...

The purpose of this study was to characterize the relation between smokeless tobacco use and the risk of all-cause and disease-specific mortality. Using data from the First National Health and Nutrition Examination Survey Epidemiologic Followup Study, the authors assessed the 20-year mortality experience of smokeless tobacco users. Subjects aged 45 years or more at baseline (1971-1975) were cat...

The major issue in selecting patients for transarterial chemoembolization (TACE) lies in determining the optimal number of TACE sessions that may benefit patients before switching to other therapies. This is often a subjective decision not based on any standardized protocol. The ART (Assessment for Retreatment with Transarterial chemoembolization) score was recently developed to determine patie...

BACKGROUND Observational studies and randomized trials have reported increased cardiovascular risk associated with cyclooxygenase-2 inhibitors. Prior placebo-controlled randomized studies had limited ability to assess the relationship of either celecoxib dose or pretreatment cardiovascular status to risk associated with celecoxib. Our aim was to assess the cardiovascular risk associated with ce...
