In this analysis of data from 2 independent samples of young adults born between October 1959 and December 1961 who were part of a prospective birth cohort study, Mortensen and colleagues found that duration of breastfeeding was associated with higher scores on 2 different intelligence measures.

Cost-effectiveness of Cervical Cancer Screening Strategies

Cervical cytology techniques other than the Papanicolaou (Pap) smear are now available, as are methods to detect cervical infection with human papillomavirus (HPV). In a cost-effectiveness analysis, Mandelblatt and colleaguesArticle found that screening with HPV plus Pap tests every 2 years appeared to save additional years of life at reasonable costs compared with Pap testing alone. Kim and colleaguesArticle conducted a cost-effectiveness analysis to compare alternative strategies for the management of women with equivocal cervical cytology results. Reflex HPV testing using either residual liquid-based cytological specimens or samples collected at the same time as screening with conventional cytology provided the same or greater life expectancy benefits and was more cost-effective than other management strategies. In an editorial, MarkArticle provides a roadmap to understanding cost-effectiveness analyses.

Needlestick Transmission of Hepatitis C: Grand Rounds at the Johns Hopkins Hospital

Needlestick exposure to hepatitis C virus (HCV) is a serious occupational hazard for health care workers. There are no approved methods of preventing HCV infection after an occupational exposure, and the optimal strategy for diagnosing HCV infection after an exposure has not been determined. Sulkowski and colleagues discuss the case of a 29-year-old medical intern who developed acute HCV infection after sustaining a needlestick injury from a source patient known to be infected with both human immunodeficiency virus and HCV.
