Factors associated with condom use among sexually active female adolescents.
A health belief model of condom use was used to identify factors associated with condom use in 390 sexually active female adolescents, aged 12 through 19 years, recruited at the time of a visit for reproductive health care. Fifty-six percent were white and the remainder black. Nineteen percent had genitourinary infections with Chlamydia trachomatis. Forty-six percent reported having had more than one sexual partner in the preceding year. Reported condom use for at least one specific reason (prevention of pregnancy, sexually transmitted disease, or acquired immunodeficiency syndrome) increased as behavioral, emotional, and sexually transmitted disease risk decreased, and as cognitive maturity and positive condom attitudes increased. Although uses of condoms to prevent pregnancy, sexually transmitted disease, and acquired immunodeficiency syndrome were positively intercorrelated, each made a contribution to explaining condom use at most recent coitus (odds ratios 2.95, 3.96, and 2.81, respectively). After statistical adjustment for the reported reasons for previous condom use, behavioral risk was the only additional factor associated with condom use at the most recent sexual encounter; women who participated in more risk behaviors (substance and alcohol use and minor delinquency) were less likely to have used a condom (odds ratio 0.61). Knowledge about sexually transmitted disease and acquired immunodeficiency syndrome, and concurrent use of contraceptive pills, were not related to condom practices. The data suggest that adolescents' perceptions about condoms, including the individual functions of condoms for contraception and for prevention of sexually transmitted disease, may be important in determining their use. Engaging in unprotected intercourse may be part of a larger behavioral domain that includes other unhealthy behaviors.
Professionalization of the older medical student.
While older applicants have traditionally had difficulty being admitted to medical schools, they slowly are gaining easier acceptance at some institutions. Little is known, however, about whether or not older medical students experience the same professionalization process as younger ones and whether or not the extensive literature developed over the past 40 years is useful in understanding older students' developmental processes. Structured interviews were conducted with 26 University of Cincinnati students who were 28 or older when they matriculated as freshmen in medical school. The findings indicated not only that these students experienced different stresses from their younger classmates but also that they cope with problems and view the professionalization process differently. These results are discussed in relation to the literature. Some suggestions for educational and counseling policies are offered.

Immune response in progressor and regressor strains of chickens at specific intervals after a primary challenge with Rous sarcoma virus.
A progressor line and a regressor line of chickens were compared for development of immune response, after an initial inoculation of Rous sarcoma virus in the wing-web. Quantitative measures of immunity were determined for the two contrasting lines of chickens at specific intervals after the initial challenge. It was found that subsequent challenges, with either Rous sarcoma virus or tumor homogenate, in the opposite wing-web were met by an early immune response from the regressor line. This early response was absent in the progressor line. However, both lines showed a similar immune response after a time interval of 15 days from the initial challenge. The genes for regression exert this early immune response which is the key to spontaneous regression of Rous sarcomas.
