Tagin et al investigate the evidence of therapeutic hypothermia for newborns with hypoxic ischemic encephalopathy.
Wilkinson discusses the idea of creating a policy of nonresuscitation based on gestational age and chronologic age and how some have questioned whether such guidelines would be considered a form of ageism. In an editorial, Lantos provides commentary on ageism.
In a cross-sectional twin-family study, van der Aa et al investigate the degree to which genetic and environmental influences affect individual differences in sedentary behavior throughout adolescence.
Researchers have begun to study the single-nucleotide polymorphisms associated with adult obesity. Belsky and coauthors used data from the 38-year Dunedin Multidisciplinary Health and Development Study to determine the effect of childhood developmental phenotype on the heritability of adult obesity. Their research has implications for clinical practice and developmental and epidemiologic studies.
To test for differences in prospective associations between physical activity and obesity among black and white adolescent girls, White and Jago analyze dose-response associations between quartiles of accelerometer counts per day and obesity in 1148 adolescent girls who provided valid data on these variables at ages 12 and 14 years.
In a cross-sectional analysis of entry data from an observational, prospective 2-year study, Nachman and coauthors evaluate associations between human immunodeficiency virus (HIV) disease severity and psychiatric and functional outcomes in youth with perinatal HIV infection.
In a longitudinal comparison study, Starr and coauthors evaluate the hypothesis that 3-year-old children with single-suture craniosynostosis would receive lower neurodevelopmental scores than a comparable group of children born with patent sutures.
Kugelman and colleagues conducted a population-based study using the Israel National Very Low Birth Weight Infant Database to assess risk factors and develop a simple estimate method for poor neonatal outcomes for specific groups of extremely premature infants at birth. The study involved infants born at 23 to 26 weeks’ gestation between January 1, 1995, and December 31, 2008.
In a cross-sectional study, Fritz et al measure prevalence of Staphylococcus aureus colonization in household contacts of children with acute S aureus skin and soft tissue infections, determine risk factors for S aureus colonization in household contacts, and assess anatomic sites of S aureus colonization in patients and household contacts.
