MRSA: rare in the vagina.

Study Objective: To determine the prevalence of vaginal Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in sexually active adolescent women.

Design: A prospective surveillance study.

Photoperiodic regulation of the orexigenic effects of ghrelin in Siberian hamsters.

Animals living in temperate climates with predictable seasonal changes in food availability may use seasonal information to engage different metabolic strategies. Siberian hamsters decrease costs of thermoregulation during winter by reducing food intake and body mass in response to decreasing or short-day lengths (SD). These experiments examined whether SD reduction in food intake in hamsters is driven, at least in part, by altered behavioral responses to ghrelin, a gut-derived orexigenic peptide which induces food intake via NPY-dependent mechanisms.

Stepwise diagnosis of Trichomonas vaginalis infection in adolescent women.

The objective of this study was to examine the effects of clinical factors and of the type and timing of a secondary test in improving the sensitivity of Trichomonas vaginalis detection in young women over that of a wet mount alone. For this purpose, sexually active adolescent women (n = 345) were recruited from a hospital teen clinic or emergency department. Following an interview and a pelvic exam, four primary T.
