Number of family caregivers supporting older adults increased nearly one-third between 2011 and 2022

The number of family caregivers supporting older adults living in home and residential-care settings increased to 24.1 million, a 32% rise from 18.2 million in 2011. Caregiving responsibilities continued to fall primarily to women, with those caring for individuals with dementia facing unique challenges.

CNIC scientists design an effective treatment strategy to prevent heart injury caused by a class of anticancer drugs

Researchers at the CNIC have designed a treatment strategy to protect the heart against cardiotoxic effects of anthracyclines, a common class of anticancer drugs. Empagliflozin, an SGLT2 inhibitor, has been shown to preserve cardiac function and metabolism in experimental models.

Painted lady butterflies migrations and genetics

A study on painted lady butterfly migrations found that environmental conditions, rather than genetic coding, drive their migratory patterns. The research revealed that butterflies can travel vast distances, crossing the Sahara Desert, without showing significant genomic differences between short and long-distance migrants.

Diabetes-linked amputations surge in Oklahoma amid national decline, OU study finds

A new University of Oklahoma study found that diabetes-linked amputations are rising in Oklahoma, with the statewide rate nearly doubling between 2008 and 2019. The study analyzed over 1.3 million anonymized discharge records and found that rates were highest among males, American Indians, and those with poor health insurance coverage.
