Short syntheses of 24-thia-5 alpha,20 xi-cholestan-3 beta-ol, 24-methyl-24-aza-5 alpha,20 xi-cholestan-3 beta-ol, and 24-nor-5 alpha,20 xi-cholan-3 beta-ol from 3 beta-hydroxy-5 alpha-pregnan-20-one are described. The products and synthetic intermediates have been fully characterized by the results of proton NMR, infrared, and high and low resolution mass spectral studies.

A university-related prepaid group practice was established in Columbia, Maryland, in 1969, by the Johns Hopkins Medical Institutions with the cooperation of the Connecticut General Life Insurance Company. Objectives were based on the traditional triad of service, teaching and research. The effort continues. There has been visible success in the achievement of each of the objectives. It is evident, however, that the development of the Columbia Medical Plan would have been facilitated if there had been a larger population base in which to market membership in the Plan, if marketing had been under the direction of the health-care provider, and if the burden of the building and running of a hospital had not been assumed. Overall, the experience suggests that the Health Maintenance Organization movement has only modest ultimate potential as an option in health-care delivery in the current economic milieu of American medicine.
To investigate the admissions process to medical school and the post-rejection behavior of unaccepted applicants, a national sample of the 16,837 such applicants to the entering medical school class of 1971-1972 was studied in 1973. The majority of the 1,933 respondents had reapplied to medical school following rejection, and 27% had gained entrance to either US or foreign schools by the time of study. Of those still unaccepted, about half were studying or working in health-related fields of study or occupations at least 2 1/2 years following the initial rejection. We conclude that unaccepted applicants demonstrate considerable variance in postrejection behavior, which is associated with both personal and institutional factors.
