Transition of care from the emergency department to skilled nursing facility: Retrospective case-control study.

Objective: The primary objective of this study is to describe associations between emergency department (ED)-to-skilled nursing facility (SNF) transition and ED length-of-stay (LOS). The secondary objective is to explore how social determinants of health (SDOH) influence ED-to-SNF transition visit parameters. In 2020, The Centers for Medicare & Medicaid Services issued the "COVID-19 Emergency Declaration Blanket Waivers for Health Care Providers" eliminating the requirement of a 3-day qualifying hospital stay before SNF placement.

Strontium-90 in Baby Teeth as a Basis for Estimating U.S. Cancer Deaths From Nuclear Weapons Fallout.

Nuclear weapons testing in the atmosphere during the 1950s and 1960s deposited fallout throughout the world, exposing all humans to food and water before the Limited Test Ban Treaty ended large-scale tests. The largest effort to measure in vivo fallout in humans, performed by Washington University (USA), collected over 300,000 deciduous teeth to document a sustained increase in Strontium-90 (Sr-90) during testing and a sharp decline after the test ban. Sr-90 patterns and trends in teeth were consistent with those of bones and milk.
