1/9 🤔 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.

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)

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?

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! jamanetwork.com/journals/jam...

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.

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

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 🤯 #EMIMCC #nephsky

Thanks to everyone who replied. Let me summarize what others have added: 💡Renal ultrasound to assess kidney size/echogenicity better differentiates AKI from CKD 💡Although PTH can increase in AKI, the magnitude of rise is greater in CKD 💡Prior labs and response to treatment are probably best!

PTH can certainly increase in AKI, however the magnitude of increase in PTH can be different in AKI vs CKD. Size of the kidneys may be helpful if the kidneys are small (although they are not always small in CKD) but kidney echogenicity can be abnormal on both AKI and CKD so it is not a good marker

Nayan Arora @captainchloride.bsky.social · 12/11/2024
Yup! Unreliable to use PTH as a differentiator because of peripheral PTH resistance and change in set point. Normalization can also lag behind a few days after AKI recovery in some cases. IMO kidney US is still the best way, ie small and/or echogenic kidneys

QUESTION 🤔How quickly does PTH increase in acute kidney injury (AKI)? I learned (and have taught) that PTH can be used to suggest chronic kidney disease. At today's Clinical Reasoning Conference, our discussion (Jeff Williams) cautioned me not to just come to this conclusion.
