We spend a lot of time and energy fussing about hyponatremia in hospital medicine, and it appears that spending even more time fussing about it does not improve patient outcomes #hospmed

Inpatient rehab days

It depends. The sweet spot for SNF care, I think, is the patient who needs 5-7 inpatient rehab to decrease fall risk so that home discharge is safer. When these patients stay in hospital, ED boarders increase (unsafe), hospitals lose money and lay off staff (unsafe), etc.

The decline in skilled nursing facility/rehab beds is a huge problem for US hospitals, contributing to longer stays and operating losses. It’s probably going to get worse as deportations ramp up and private equity runs more rehabs into the ground

After more than 15 years on the platform formerly known as Twitter, Cambridge is leaving X - The Boston Globe City councilors in the liberal enclave voted unanimously to leave a platform they said had become toxic under owner Elon Musk.

Hey, the City of Cambridge finally left X! May more orgs follow suit. (You can find them here at @cambridgemass.bsky.social instead...)

The recommendations for Germany, Poland, Spain, the UK, and Finland are based on wastewater surveillanceβ€”*not* actual human cases

If you’ve had a primary series in childhood, should get a one-time dose of inactivated polio vaccine (IPV) before travel, and you don’t have to worry about it again

Requiring Annual N95 Mask Fit Testing Is a Waste of Time and Money Is it time to replace annual N95 mask fit testing with a less expensive, evidence-based policy?

In this @nejm.org Voices post, I take on one of the more annoying and pointless rituals of hospital work -- the annual N95 fit test.
As one of the respected infection control specialists told me, it's not their fault. And I totally believe them. #idsky #medsky

What the heck is going on with these springbok?
(other than "hidden trampoline concealed in the grass")

The stiff-legged jumping behavior shown here is called "pronking" or "stotting" & it's a bit of a puzzle why they do it.

It's observed in a wide variety of ungulates under different conditions.

A Penguin Books paperback of The Secret History by Procopius

History is my go-to escapist reading! This one is about a corrupt and venal king who married a sex worker, mismanaged a pandemic because he knew nothing about public health, and frittered away his kingdom’s wealth and prestige in a series of ill-advised military adventures

It is nice to be on one of the few remaining types of social media that isn't absolutely riddled with genAI sloptivity. They may take our images and videos but I'll be damned if they take our pithy short-form written existential angst

Elite Doctors Served Jeffrey Epstein While Treating His β€˜Girls’

Emerging Endemic Area for Blastomycosis, New York, USA, 2000–2024 Blastomycosis, New York, USA, 2000–2024

The Northeast US is getting wetter with climate change, which may favor outbreaks of the fungal infection blastomycosis. Blasto seems to be emerging in upstate New York; prior reports have suggested that blasto is also on the rise in New England (immunosuppressive drugs may also be a factor)

Public investment in NIH research helped turn cystic fibrosis from a childhood killer into a survivable disease. Russ Vought is now withholding funding from the very system that made that made that future possible for his daughter.

No, that side effect is peculiar to measles (and probably also to COVID).

Possible mumps exposure at 2 Berkeley schools, report says: Here's what to know Two schools in Berkeley reportedly sent out a warning following a possible exposure to mumps on campus.

Mumps activity now in California and Maryland

Mumps (R0 10-12) is not quite as contagious as measles (R0 12-18), but it's pretty close. Serious complications include encephalitis, meningitis, orchitis (testicular inflammation), myocarditis, pancreatitis, and nephritis

Interesting modeling study that attributes extinction of B/Yamagata during the pandemic to:
- masking, masking, masking
- slow rates of antigenic change, compared to B/Victoria
- a huge 2017/2018 outbreak that depleted the susceptible population

Map of Northern Athabaskan (Alaska, Yukon, Northwest Territories, BC, AB,SK) and Southern Athabaskan (US Southwest) language families

Fun fact: in 852 CE, there was a massive eruption of Mount Churchill in Alaska, which forced a bunch of Dene speakers to migrate south, where they became the Apache and the Navajo. That’s why Athabaskan is the most widely dispersed indigenous language family in North America
