The Jackson Heart Study is a partnership among Jackson State University, Tougaloo College, the University of Mississippi Medical Center and the National Institutes of Health's National Heart, Lung, and Blood Institute (NHLBI) and Office of Research on Minority Health. The purposes of the study are to: (1) establish a single-site cohort study to identify the risk factors for the development of cardiovascular diseases, especially those related to hypertension, in African American men and women; (2) build research capabilities in minority institutions by building partnerships; (3) attract minority students to careers in public health and epidemiology; and (4) establish an NHLBI Field Site in Jackson, Mississippi, similar to those established for the Framingham Heart Study and the Honolulu Heart Program. ⋯ The study will have a sample size of approximately 6,500 men and women aged 35-84 years and will include approximately 400 families. Exam 1 is scheduled to take place in the spring of the year 2000.

Hypertension, left ventricular hypertrophy (LVH), hypercreatininemia, and microalbuminuria (MA) are independent risk factors for cardiovascular disease (CVD). Hypertension increases the risk of CVD by two- to three-fold and LVH (especially concentric) is a risk factor for coronary heart disease, heart failure, stroke, and peripheral arterial disease. ⋯ Impaired renal sodium handling and sodium retention are physiological hallmarks of the very early stages of heart failure. Heart failure is a physiologically delicate condition that can decompensate with excess dietary salt intake or over diuresis, or compensate with cautious therapy designed to block the sodium retention and simultaneously interrupt excessively activated neurohumoral mechanisms.

Case Reports
Resolution of adult respiratory distress syndrome after recovery from fulminant hepatic failure.
Adult respiratory distress syndrome (ARDS) complicating the course of fulminant hepatic failure is nearly always fatal without orthotopic liver transplantation. We report the case of a 50-year-old woman with fulminant hepatic failure and ARDS that resolved after her recovery from the acute liver failure without liver transplantation. The pathogenesis is discussed, particularly with regard to liver-lung interactions.

The continuing legacy of the Tuskegee Syphilis Study: considerations for clinical investigation.
The Tuskegee Study, an observational study of over 400 sharecroppers with untreated syphilis, was conducted by the U. S. ⋯ The study became the longest (1932-1972) nontherapeutic experiment on humans in the history of medicine, and has come to represent not only the exploitation of blacks in medical history, but the potential for exploitation of any population that may be vulnerable because of race, ethnicity, gender, disability, age or social class. It is important for physicians who will be caring for an increasingly diverse nation to understand the lasting implications of this study for their patients, but the effects of the Tuskegee Syphilis Study are demonstrated most strikingly by unsuccessful attempts at improving representation of minority patients in clinical trials.
