2 years? I think we need a plan for a 2 week update!

Should we have continuously updated recs based on when new evidence comes out? I think NCCN cancer guidelines are like this

I have a hard time seeing how we progress from a smorgasbord of individually good therapies to a systematic approach as to which one(s) is (are) best for an individual patient

It’s a good problem but a problem nonetheless

I think it we need trials with bi-pronged approaches; it’s tough when no one company (until maybe recently) has therapies in both the immune-modulatory and general nephron preserving camps.

Complement inhibitor had been published on a year before the guidelines were released!

And who knows what’s going to happen at #kidneywk?

Is there a plan for a v2025.2?

Josh Waitzmanβ€”I work full-time for Vertex and part-time at BIDMC.

COI: Vertex has an ongoing trial of a BAFF/APRIL inhibitor.

Opinions are my own and I only know what’s public.

Urine screening to early diagnose young individuals with CKD: a call for action Alport syndrome is an inherited disorder of basement membranes leading to progressive chronic kidney disease, hearing loss, and ocular abnormalities in many affected patients. When the authors started...

If treatments are available that can help at early stages of most causes of CKD (RAASi, SGLT2i, etc), why WOULDN’T we screen? Economics? How much does saving 20 years of dialysis get you? What about human costs?

In case folks missed this, ACGME Transplant Nephrology accreditation is now a thing!

If folks are Program Directors, they may need to start the process of accreditation soon.

NIH Student Grant Cancellation Will Weaken Scientific Innovation The termination of federal F31 diversity fellowships puts many graduate students in a bind β€” and U.S. science at risk.

This is a powerful account from a PhD student whose fellowship was terminated by NIH because it was part of a "diversity" program without any other considerations or understanding of what the program or the students were actually doing.

Pre #nephjc bias: Team pro protein

All these studies are deeply confounded and based in the pre-kidney-preserving therapy era.

Let them eat steak!

(Actually, let them eat vegetable sources of protein, but beans, lentils, and soy don’t rhyme with cake)

NIH Leadership Is Failing Early Career Researchers Halted training programs, funding chaos, and hiring freezes jeopardize advancement options for early career researchers.

My op-ed just came out discussing how NIH leadership is failing early career researchers and, importantly, how we can push back and take our future into our own hands.
