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
hemorrhagic fever viruses as biological weapons are presented in this sixth
consensus statement in the series from the Working Group on Civilian Biodefense.
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.
Ludwig reviews the glycemic index, a system for classifying carbohydrate-containing
foods according to glycemic response, and the relationship between glycemic
index and physiological mechanisms relating to obesity, diabetes, and cardiovascular

Concern about approval by the Accreditation Council for Graduate Medical
Education of a proposed yearlong PGY5 fellowship designed to set uniform standards
in dermatologic surgery has sparked controversy between the American Academy
of Dermatology and the American College of Surgeons.
