President Vladimir Putin has sought proposals from his armed forces commanders on how they think Russia's military campaign in Ukraine should proceed during a visit to the operation's headquarters, the Kremlin said. https://t.co/QcXdsF82ZD

@thematttsai @tony_breu @ShreyaTrivediMD @AdamRodmanMD @SK_Sundararaman @kandersonMD21 @DxRxEdu @rabihmgeha @AvrahamCooperMD @kidney_boy Awesome tweetorial! I actually don't find urinary indices like FeNa or FeUrea very helpful. Practices may vary among nephrologists but I find that most also don't put much stock in them. H&P plus urine Na to see if sodium avidity can be mounted are usually sufficient

Awesome 🧵 on water treatment for dialysate

[Derek Larson, MD, FASN @DerekSLarson]

Ever wonder how dialysis units make that fancy, high-quality water? It has always interested me as a nephrologist. Here's a 🧵with photos👇 1/12

[Eric Xu @immaculatedensa]

@luke_hedrick Only thing I might add is that Uosm is not a perfect proxy for ADH. Can be high because the kidneys are dumping other solutes out, e.g. urea when recovering from an AKI. Can estimate the electrolyte-free water clearance in these scenarios

[Janewit Wongboonsin, MD, MS @janewitwong]

Is it time to officially welcome #SGLT2i to acute volume overload patients? Most of my experience has been loop/diuril. What has been other experience? #flozinate https://t.co/jTjMy76NSM

"Nephrologists know Cr is an imperfect assessment of such a perfect organ"

[Amy Yau @amyaimei]

So what is worsening renal function (WRF) all of these cardiologists talk about.

Isn’t it just acute kidney injury (AKI)?
Is it a necessary evil? The kidney is the sacrificial lamb to the heart?

A nephrologist’s perspective (and personal musings). #cardiotwitter #nephtwitter

“Filtered sodium (ever the optimist) knows that when one door closes, another one (or three) may open”. Pure poetry ….

[Joshua Waitzman, MD PhD @Jwaitz]

Is there any better way to celebrate #nephmadness than by getting more options to treat and prevent kidney disease?

I’m looking forward to seeing the full results of EMPA-KIDNEY which included pts with:
-GFR down to 20
-UACr below 300

[Zaven Sargsyan @sargsyanz]

ACE inhibitors and ARBs are not “nephrotoxins.”

They improve renal blood flow.

But they reduce GFR, and impair potassium elimination.

Which is why we might hold them in [severe and/or worsening] AKI.

Happy #WorldKidneyDay! Apparently, I need special socks for this? #sockittokidneydisease @themarcusfoo

@AndrewElHayek @themarcusfoo Looks like 'Bron was dropping knowledge on the Hoop of Henle

[Eric Xu @immaculatedensa]

@AndrewElHayek @themarcusfoo I'm on consults right now and can confirm this is 100% accurate
