🤔 Why doesn't an elevated BUN lead to extreme thirst? If increased serum osmolarity compels us to seek water, uremia should be a significant driver of this craving.

And yet, it isn't.

Let's examine why.

Portal hypertension and the development of varices

If only there was a way to block the alpha and beta adrenergic pathways to offset these changes

IF ONLY!!!!

Glucose IS an effective osmole in the absence of insulin or insulin resistance. So hyperglycemia does lead to polydipsia (and polyuria due to osmotic diuresis)

Sigh. Only about half of veterans with cirrhosis hospitalized with SBP received guideline-directed IV albumin:

Rates increased from 2008 to 2022, but disparities persistent: black patients were less likely to get albumin than white patients.

Lots of work to do.

I'm in favor of still calling them #tweetorials as well. It feels delightfully anachronistic and points to the roots/history on the other platform. #MedSky, who is with me?
I agree, Liz.

I favor continuing to call them tweetorials or using something that applies to all platforms (e.g., MedThread or EdThread).

Using something unique to each platform makes less sense to me. If I post a GIF or video, it's called a GIF or video, regardless of the site.

Honey, stop what you're doing, new hyponatremia research just dropped!

What's it say?

It looks like slow correction is associated with worse outcomes, like death and length of stay!

Was it just a small study?

No, it was a meta-analysis of almost 12,000 patients!

Correction Rates and Clinical Outcomes in Hospitalized Adults With Severe Hyponatremia
This systematic review and meta-analysis evaluates the association of sodium correction rates with mortality among hospitalized adults with severe hyponatremia.

What is the mechanism of pruritus/itching in Hodgkin Lymphoma (HL)?

For today's Morning Report, Chief Resident Carter Baughman shared a case of HL that presented with months of pruritus. I was surprised to learn that up to 30% of patients with HL present with this symptom.

I did not realize we are 60% oxygen by weight until today

Makes sense though. Neat. 🙂

To begin, it's essential to understand which elements make up the human body. Amazingly, just six compose >98% of your weight:

➤Oxygen: 61% (varies based on water composition)
➤Carbon: 23%
➤Hydrogen 10%
➤Nitrogen: 2.6%
➤Calcium: 1.0%
➤Phosphorus: 0.6%

This is fascinating. When can we expect to see this in print?
This study by challenges dogma

@anandvkulkarni.bsky.social gave a tapering dose of prednisone for alcohol hepatitis instead of 40mg for 28 days

And it paid off with fewer infections

I used @en.blueark.app to transfer tweetorials previously posted on Twitter here to @bsky.app. Very fair price and quick process.

If you do the same, note my previous comments, particularly regarding links and search.
A few observations on BlueSky, after a week of use:

☞REPOSTS v LIKES: I don't see what others like, so reposts seem more powerful
☞LINKS: These consume the number of characters in the link, not a set amount (like Twitter)
☞SEARCH: I'm underwhelmed. It doesn't consistently result posts I know exist

Ok, #SciSky… what are we calling a thread that explains a research paper? (What used to be a tweetorial.) Skysplainer? Blutorial?? Let’s see ‘em!

Why not still call it a tweetorial? That other platform is “X”

We don’t have to give up tweeting because Elon and Jack did.

This radiologist applauds this thread. Btw, you can also go the other way, I’ve used air (careful where you put it!) and CO2 as “inverse” contrast in people allergic to Iodine contrast.

one cause of hypernatremia in ICU = recovery from AKI!

[1] urea *accumulates* while kidney is failing…

[2] kidney recovers➡️ clearance of accumulated urea obligates the excretion of H2O

(similar to using oral urea to tx hypoNa)

so hypernatremia can be a sign of renal recovery 🤯
