Figure. Computed tomography angiography (CTA) of subclavian artery stenosis. Axial CTA image of this patient with subclavian artery stenosis. A, Patent subclavian artery (indicated by the arrow) distal to the site of the occlusion. B, A more inferior axial image with an absence of contrast in the subclavian artery at the level of the subtotal occlusion while (C) demonstrates the most inferior and proximal to the aortic arch and re-demonstrates a patent proximal portion of the subclavian artery. This is consistent with a subtotal occlusion of the subclavian artery with distal reconstitution likely via the left vertebral artery

Our topic:
Use of dapagliflozin (SGLT2 inhibitor) in patients with autosomal dominant polycystic kidney disease (ADPKD) concurrently on tolvaptan therapy. There are no conflicts of interest.

I order it in resistant hypertension or young patients with hypertension. I admit I have a wonderful endocrinologist team who helps me interpret results and go further with more tests if necessary.

Do this interfere on your decision making? Having proteinuria <1 gr or >2 gr can make a difference in some patients.

Now that we are in the subject, do you have any specific use for Cr excretion? Do you consider any specific value for “high” and “low” or just go with what your lab parameters?

Correlación entre el cociente proteína/creatinina en orina esporádica y las proteínas en orina de 24 horas

All I found was this study, which concludes that there is a strong correlation between both tests. In my clinical practice, this is not the case. I want to hear everyone’s thought on this. Here to learn!

A question to all Nephrologists, how do you approach the difference in proteinuria between samples of spot urine and 24 hr urine?

In this example:
- Spot Urine Alb/Cr ratio: 938 mg/g
- 24 hrs: 2,177 mg/24 hrs

My calculations for Alb/Cr ratio in 24 hr is 985 mg/g

ACEing the management of advanced CKD — NephJC This week we come to meta-analyse, strikingly late, the cornerstone of all CKD treatments. Are you still in doubt? We need ACEing CKD to the end of GFR, and beyond

Is it ever too late to start RAS inhibitors in CKD?

Afraid of RASi on advanced CKD? Should we initiate ACEi and ARBs in stage 4 CKD? Is it safe? Is it worth the risk? Find the answers in this week’s #NephJC blogpost about the most recent meta-analysis on the subject.

Spoiler: Keep Calm and Aceit!

I understood that a solute is or not an effective osmole not because of its ability to permeate a cell membrane but it’s a ability to create a gradient by “dragging water”. Am I wrong about this?

Saying urea isn’t an effective osmole is confusing to me, because of desequilibrium syndrome.
