Picornavirus etiology of acute infections among hospitalized infants.

Background: Enteroviruses (EV) and parechoviruses (PeV) are ubiquitous viruses that cause a range of illness, including acute illness in children aged <1 year.

Objectives: We describe EV and PeV infections among children from 2 US study sites aged <1 year and hospitalized with acute infections. For EV- and PeV-negative case-patients, we explored other viral etiologies.

Neighborhoods matter. A systematic review of neighborhood characteristics and adolescent reproductive health outcomes.

This systematic review examines the relationship between neighborhood characteristics and adolescent pregnancy, contraceptive use, sexual initiation, and birthrate. Several studies found a significant association between higher poverty and increased adolescent birthrate, pregnancy, and earlier age at sexual initiation. Unsafe neighborhoods were associated with earlier sexual initiation and increased adolescent pregnancy.
