Cutting health care costs isn't easy

A new study from the University of Iowa found that improving access to affordable primary care reduced preventable hospital stays for black and Hispanics who receive both Medicare and Medicaid. However, it also showed that trips to the emergency department went up among all dual eligibles, regardless of race or ethnicity. The study sug...

Heart attack treatment hypothesis 'busted'

Johns Hopkins scientists discovered that blocking calcium from entering mitochondria in heart cells didn't prevent cell death after heart attacks, but rather activated alternative pathways. The study's findings challenge the long-standing theory of using calcium channel blockage to prevent heart attack damage.

UPitt researchers find link between neighborhood quality and cellular aging

A study by University of Pittsburgh researchers found a significant link between living in neighborhoods with high crime and vandalism and biological aging processes. Telomere length, a key indicator of cellular health, was found to be shorter in individuals from disadvantaged areas, similar to a 12-year chronological age difference.

Being calm is contagious?

A study published in PLOS Computational Biology reveals that woodlice can calm their excited neighbors through a process of behavioral contagion, leading to greater group cohesion. This phenomenon is observed when calm individuals reduce the excitation of their neighbors, causing them to become calm as well.

Single 30-day hospital readmission metric fails to reflect changing risk factors

A new study suggests that the standard 30-day hospital readmission metric fails to accurately reflect changing risk factors. Researchers found that early readmissions (0-7 days post discharge) were associated with acute illness markers, while late readmissions (8-30 days post discharge) were more closely tied to chronic illness burden.

No improvement in cognition with post-menopausal hormones

A recent study found that post-menopausal hormone therapy did not improve cognitive function, but may have benefits for certain mood symptoms. The trial included 693 recently postmenopausal women and followed them for four years, with some women experiencing improvements in mood symptoms.

How sleep helps us learn and memorize

A study published in PLOS Computational Biology found that sleep strengthens and weakens synapses, leading to memory erasure or new memories. The results provide an empirical framework for understanding the complex role of sleep in learning and memory.

UK population is becoming overweight and obese at younger ages

A study of over 56,000 people born in Britain from 1946 to 2001 found that most of the rise in BMI has been due to increases at the upper end of the distribution, with childhood obesity more prevalent among younger generations. The age at which adults enter the overweight range decreased over time.

Patient portals could widen health disparities

A new study found that patient portals exacerbate existing health disparities, with less educated and minority patients being less likely to use electronic medical records. Patients with low health literacy skills were 3.5 times more likely to be registered than those without these skills.
