Mechanistic signatures of comorbid PTSD with cognitive impairment implicate cortisol-induced neural toxicity - Neuropsychopharmacology Neuropsychopharmacology - Mechanistic signatures of comorbid PTSD with cognitive impairment implicate cortisol-induced neural toxicity

New paper alert πŸ§ͺ! In this study, one of our fantastic students used functional connectivity to profile neurobiological signaling in responders with post-traumatic stress disorder. We found evidence of cortisol-induced neurotoxicity in PTSD-related dementia.

NPS removes Native American signage at Little Bighorn National Monument NPS recently removed signage at Little Bighorn National Monument under Trump's "Restoring Truth and Sanity to American History" executive order.

Due to a trump executive order the national parks service has removed signage at the little bighorn battlefield that amplified the broken treaties and the assimilationist american policy of "kill the Indian save the man" that led to the reeducation 1/2

We examined whether PTSD (or Major Depression) predicted Mild Cognitive Impairment in Firefighters who responded to the WTC attacks. We found it matters! But also that PTSD only explains about 10% of impairment. www.sciencedirect.com/science/arti...

9/11 responders reporting severe dust exposures had up to 2.9x greater risk of developing lung cancer >10 years after exposure.

Measles isn't just a rash

Pneumonia - 5-10%
Encephalitis - Brain inflammation (~1 in 1,000), risks permanent damage
SSPE - Rare fatal brain disorder, 7-10 yrs later
Ear infections - 10%, may cause hearing loss
Blindness - Corneal damage
Immune amnesia - Vulnerability to other infections for mos/yrs

Measles requires 95% vaccination rates for herd immunity.

It has a 16.2% case fatality rate for unvaccinated children under 5 years and 24% for children under 9 months (who are unable to be vaccinated).

30% of the survivors experience severe complications like blindness, deafness, or encephalitis.

Smallpox used to kill >1/3 people.
In 1796, Edward Jenner noticed that milkmaids who had had cowpox (a mild form of smallpox) seemed immune to smallpox. So he inoculated a child (not ethical today) and the child was also immune. The first vaccine! The original: books.google.com/books?id=QQm...

I also think it mistakes recipients for awardees. It states: β€œβ€¦award recipients are subject to a 15 percent indirect cost rate… (to) allow grant recipients a reasonable and realistic recovery of indirect costs”. The recipient is obv. the Univ. Who makes that error?

COVID-19 may accelerate dangerous hardening of the arteries Researchers have identified new clues about why COVID-19 infection increases the risk of longer-term heart attacks and heart failure.

The lingering effects of #COVID19 are more than just fatigue. New evidence suggests the virus may cause long-term artery damage, raising heart disease risk in millions. Here’s what that means:

Republican calls to scrap workplace safety agency Representative Andy Biggs made an earlier bid to abolish the Occupational Safety and Health Administration in 2021.

Republicans have introduced a bill to abolish OSHA.

As a former labor secretary, I know firsthand how crucial this agency is to protecting workers from bosses who cut corners on safety to pad their own pockets.

This is the party of corporate greed, not the party of workers.

How Should Health Care and Public Health Respond to the New US Administration? This Viewpoint discusses scientific, medical, and public health actions, including withdrawing from the World Health Organization, taken so far during the first week of the Trump administration.

"To condone policies that the profession knows will compromise healthβ€”or to remain silent and look awayβ€”is to be complicit in putting population health at risk"

To every university, every public hospital, every academic society: SILENCE IS NOT AN OPTION. #medsky
