Disparities in postpartum readmission by patient- and hospital-level social risk factors in the United States: a retrospective multistate analysis, 2015-2020.

Background: Postpartum readmission is an area of focus for improving obstetric care and reducing costs. We examined disparities in all-cause 30-day postpartum readmission by patient- and hospital-level factors in the United States.

Methods: We conducted a retrospective cohort study using 2015-2020 records from the State Inpatient Databases from four states.

Elemental Characterization of Ambient Particulate Matter for a Globally Distributed Monitoring Network: Methodology and Implications.

Global ground-level measurements of elements in ambient particulate matter (PM) can provide valuable information to understand the distribution of dust and trace elements, assess health impacts, and investigate emission sources. We use X-ray fluorescence spectroscopy to characterize the elemental composition of PM samples collected from 27 globally distributed sites in the Surface PARTiculate mAtter Network (SPARTAN) over 2019-2023. Consistent protocols are applied to collect all samples and analyze them at one central laboratory, which facilitates comparison across different sites.

Racism, COVID-19, and Health Inequity in the USA: a Call to Action.

The current national COVID-19 mortality rate for Black Americans is 2.1 times higher than that of Whites. In this commentary, we provide historical context on how structural racism undergirds multi-sector policies which contribute to racial health inequities such as those highlighted by the COVID-19 pandemic.
