Previous studies have suggested that breastfeeding is positively associated
with cognitive development in early and middle childhood. 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.
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.
Recommendations for medical and public health management after use of

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.
Ludwig reviews the glycemic index, a system for classifying carbohydrate-containing
foods according to glycemic response, and the relationship between glycemic
