Great read, thanks yall.

I’ve always been struck by how some folks have a lot of synthetic/hepatocellular dysfunction but little portal hypertension.. or vice versa.

Good argument that the relative contributions of each to MELD-Na might be actionable in this context..

Me too! It's crazy how heterogenous the phenotypes can be despite having the same pathophysiology. At least, as we currently understand it.

When asked by a denier about what proof I have that #UrineMicroscopy makes a difference (often w/a “I’ve been practicing 30 yrs without it”), my answer is that one cannot grasp the full extent of missed information by ignoring a tool when there’s lack of proficiency on how to properly use the tool

Improving biopsy adequacy rates is essential to improving patient care.

To understand more about the renal biopsy adequacy crisis, listen to our podcast: youtu.be/GSUhu9ysNyM?...

Strong signal for better kidney biopsy adequacy favoring 16G needle over 18G (w/ = complication rate) in pediatric pts 12-18 years-old, extending established norm 4 adults. Only 4 children <12, a smaller 18G needle is safer. #KidneyBiopsyAcademy @kidneycon.bsky.social @arkanalabs.bsky.social

How did the frequency of inadequate renal biopsies go from <1% in 2004 up to 27% in 2025?

Check out this article by Dr. Justin Belcher & many collleagues from Yale GI showing kidney tubular secretion can distinguish ATI from other AKI causes in cirrhosis patients - a game-changer for treatment decisions! @asnpublications.bsky.social #CJASN🔬

Sperati uses the Osler quote "He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all." to critique the GlomCon model that provides books but does not provide patients #GlomCon

What exactly is an inadequate renal biopsy? Why are 27% of biopsies inadequate? What can be done to fix this?

Check the thread to listen to @nephrosharma.bsky.social, @glombandit.bsky.social, @nephrowhitt.bsky.social, and @juancarlosqvelez.bsky.social discuss this challenge. #RenalPath #RenalSky
