Background: Air pollution may impair child growth and cognitive development, with potential markers including birth length and head circumference.

Methods: The Household Air Pollution Intervention Network (HAPIN) trial was an open label multi-country-randomized controlled trial, with 3200 pregnant women aged 18-34 years (9-19 weeks of gestation) randomly assigned in a 1:1 ratio to receive liquefied petroleum gas (LPG) stove intervention compared to women continuing to cook with solid fuels for 18 months. Particulate matter ≤ 2.

Addressing health inequities requires both national and local-level action. In the case of COVID-19, locally-led place-based programs were instrumental in addressing vaccination inequities that resulted from implementation gaps in national and state-level universal COVID-19 vaccination programs. To prepare for future pandemics, understanding which local strategies are effective and the conditions that enable their effectiveness is crucial.

Multimaterial 3-D printing (3DP) of isotropic (IsoE) and liquid crystalline elastomers (LCE) yields spatially programmed elements that undergo a cuboidal shape transformation upon heating. The thermomechanical deformation of 3DP elements is determined by the geometry and extent of the isotropic and anisotropic regions. The synthesis and experimental characterization of the 3DP elements are complemented by finite element analysis (FEA).

Background: Rotavirus vaccines are moderately protective against illness in high mortality settings compared with low mortality settings. Vaccine effectiveness (VE) evaluations may clarify our understanding of these disparities, but estimates among key subpopulations and against rare outcomes are not available in many analyses due to sample size. We combined 25 datasets from test-negative design case-control evaluations in 24 countries that enrolled children with medically-attended diarrhea, laboratory-confirmed rotavirus stool testing, and documented vaccination status.

Antidepressant medications, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are commonly used to treat depressive, anxiety, and obsessive-compulsive disorders in youth. Yet, data on discontinuing these medications, withdrawal symptoms, and strategies to switch between them are limited. We searched PubMed and ClinicalTrials.
