Effects of a liquefied petroleum gas stove and fuel intervention on head circumference and length at birth: A multi-country household air pollution intervention network (HAPIN) trial.

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.

Assessment of Lead Exposure and Associated Risk Through Human Biomonitoring Among Urban Communities in Chennai, Southern India.

Background: Lead exposure is a widely acknowledged risk to public health for children and adults. However, despite efforts to phase out major sources over the last several decades, estimates of the prevalence of blood lead exposures and associated risks remain poorly characterized in many low- and middle-income countries.

Objectives:  This study aimed to determine blood lead levels (BLLs) and assess potential sources of lead exposure among urban communities in Chennai, Tamil Nadu.

Elevated Expression of Cell Adhesion, Metabolic, and Mucus Secretion Gene Clusters Associated with Tumorigenesis, Metastasis, and Poor Survival in Pancreatic Ductal Adenocarcinoma.

Objectives: Technological advances in identifying gene expression profiles are being applied to study an array of cancers. The goal of this study was to identify differentially expressed genes in pancreatic ductal adenocarcinoma (PDAC) and examine their potential role in tumorigenesis and metastasis.

Methods: The transcriptomic profiles of PDAC and non-tumorous tissue samples were derived from the gene expression omnibus (GEO), which is a public repository.
