#AskRenal in 2007 KI published this paper showing massive albumin filtration at the glomerulus in norml kidneys shattering decades of dogma regarding the negative charge in the glom. pubmed.ncbi.nlm.nih.gov/17228368/
What is the current thought?
A) The classic, glomeruli are impermeable to albumin
B) The rebel, glomeruli leak a lot of albumin that is normally reabsorbed in the proximal tubule
Please reply with the real answer the poll is for fun but won't help me answer my question

When we published our study <> of ODS and hyponatremia we were pummeled for including people at low risk of ODS because we included Na levels between 120 and 130. They said it is well known "that ODS is incredibly rare/non-existent at those levels." 1/4evidence.nejm.org/doi/10.1056/EV…
Of course one of the reasons it was thought to be incredibly rare was that no one looked for CPM in patients with Na from 120-130. We found a fair number (≤5 of 12). 2/4
Our findings are replicated in a study from Australia. The authors took a different approach to investigating ODS. Instead of starting w/ hyponatremia and working forward to ODS, they started with a dx of ODS and worked backwards

Gadolinium in dialysis patients.
What's up with that?

Nephrogenic systemic fibrosis (NSF) is an iatrogenic disease that presents with hardening of the skin and other organs. It is often lethal. I treated 5 people with this condition (including one with AKI). Terrible.

The etiology of NSF was unknown and there were many theories. In 2006, Thomas Grobner published a small case series showing 5 patients developing NSF within weeks of receiving gadolinium contrast for MRI.

I just recently recommended the Renal Physiology book by Bruce Koeppen and Bruce Stanton. I thought it was a good medical student level text book: pbfluids.com/2023/08/ouwb-s…
But I came across this question in Chapter 8 Regulation of Acid Base. It is a straight forward question asking the learner to interpret simple acid-base cases.
But the question falls apart when you look at the answer...

These are real cases
The osmolality was 294, so there is a huge gap. 44ish
