To determine whether elevated serum cholesterol level is associated with all-cause mortality, mortality from coronary heart disease, or hospitalization for acute myocardial infarction and unstable angina in persons older than 70 years. Also, to evaluate the association between low levels of high-density lipoprotein cholesterol (HDL-C) and elevated ratio of serum cholesterol to HDL-C with these outcomes. ⋯ Our findings do not support the hypothesis that hypercholesterolemia or low HDL-C are important risk factors for all-cause mortality, coronary heart disease mortality, or hospitalization for myocardial infarction or unstable angina in this cohort of persons older than 70 years.

Comparative Study
The National Health Service Corps experience for rural physicians in the late 1980s.
To learn from physicians in the National Health Service Corps (referred to as NHSC or the Corps) scholarship program about their experiences in rural health professional shortage areas (HPSAs), to contrast their experiences with those of other physicians working in rural HPSAs, and to learn how NHSC physicians' retention is associated with the quality of their experiences. ⋯ The needs and preferences of NHSC physicians and families are not well accommodated. Low morale and poor retention are endemic among NHSC physicians. The NHSC is challenged by twin goals of meeting the immediate needs of underserved communities and providing personally and professionally satisfying environments where physicians can pursue long-term careers.
