Perceptions of factors influencing the introduction and adoption of electronic immunization registries in Tanzania and Zambia: a mixed methods study.

Background: As technology has become cheaper and more accessible, health programs are adopting digital health interventions (DHI) to improve the provision of and demand for health services. These interventions are complex and require strong coordination and support across different health system levels and government departments, and they need significant capacities in technology and information to be properly implemented. Electronic immunization registries (EIRs) are types of DHI used to capture, store, access, and share individual-level, longitudinal health information in digitized records.

Urinary arsenic is associated with wasting and underweight status in young children in rural Bangladesh.

Background: Deficits in child growth are associated with poor cognitive outcomes and an increased risk for infection and mortality globally. One hundred forty million people are chronically exposed to arsenic from contaminated drinking water worldwide. While arsenic exposure has been associated with cognitive developmental delays in children, there is limited research on the association between arsenic exposure and growth deficits in young children.
