Presented at #CCR26: Among critically ill adults with metabolic acidosis receiving vasopressors in the ICU, sodium bicarbonate did not lead to a lower risk of major adverse kidney events within 30 days than placebo. Full SODa-BIC trial results: nej.md/4ofXcyq @CritCareReviews

Epic @FreelyFiltered last night with Megan Prochaska David Goldfarb and John Asplin talking about the PUSH trial. I pushed as hard as I could but I couldn't get them to admit that water had no role in the prevention of kidney stones!

Presented at #CCR26: Among adults with septic shock, the use of restricted fluids and early vasopressors did not result in more days alive and out of the hospital through day 90 than the use of liberal fluids and later vasopressors. Full ARISE FLUIDS trial results: nej.md/3PVdwIp @CritCareReviews

Ha salido la nueva guía 2026 del síndrome cardiovascular-renal-metabólico (CKM) y trae cosas interesantes. Os dejo lo que me parece más destacable, lo bueno y lo que no me cuadra tanto 🧵 @AHAScience @ACCinTouch @AmDiabetesAssn @ASNKidney Corazón, el riñón y el metabolismo no van por separado. Y es bueno ponerlo también sobre el papel. Lo que más me gusta: → Se estadifica el CKM (0 a 4), también en niños, para frenarlo a tiempo y hasta hacerlo retroceder. → La obesidad se trata como la raíz, no como un factor más de la lista. POR FIN. → iSGLT2 y GLP-1 como modificadores de enfermedad → Mirar siempre el riñón con FGe cociente albúmina/creatinina. → Y meten los determinantes sociales en la ecuación. Sigo 👇

Published today, the first-ever clinical practice guideline on cardiovascular-kidney-metabolic (CKM) syndrome from the American Heart Association and @ACCinTouch. The focus of this clinical practice guideline is to create a living, working document that provides current knowledge in the field of CKM syndrome aimed at all practicing cardiologists, endocrinologists, nephrologists, and primary care and specialty clinicians who manage these patients. ✍🏼 @ChiadiNdumele @HeartDocSadiya @kardiologykazi @noshreza @virani_md @biykemb @NutritionHF @mandeepbajaj65 @KatherineTuttl8 @RangaswJ @lisaVWMD @KBreathettMD @EmoryFamMed @ShoaClarke @mad_sters @jmortonmd @sripalbangalore @AnumSaeedMD

In-hospital initiation of SGLT2 inhibitors in acute heart failure shows consistent benefit across RCTs (n=4,096; 8 trials): starting SGLT2 inhibitors during hospitalization for acute HF may improve survival and short-term outcomes without added safety signal.

Kidney biopsy: Great teaching case Severe inflammation and necrosis with abscess formation. Look carefully=you see cells with large nuclei in the mix of inflammatory cells. IHC= Positive staining for ADENOVIRUS. DX: Adenovirus-associated interstitial nephritis. 55-yr old with kidney & heart transplant, fevers, rise in serum creatinine.

#ERA26 PRO vs Con debate: should we lower SBP under 120 mmHg? Taking the PRO arguments @AgarwalRajivMD 📍Of course mentioning SPRINT, where targeting SBP <120 mmHg ⬇️ CV events, heart failure, CV death, and all-cause mortality versus <140 mmHg 📍Benefits emerged despite a modest achieved BP difference (~13 mmHg) and 👉to early trial termination 📍In CKD subgroup, intensive BP control: similar cardiovascular and survival benefits 📍No clear ⬇️ in kidney outcomes, but CKD did not diminish CV benefit of intensive treatment

Among adults with chronic #kidney #disease (#CKD) due to glomerular diseases, finerenone slowed eGFR decline, reduced albuminuria, and lowered risk of kidney failure, with consistent benefits across disease subtypes and in those using #SGLT2 inhibitors. #ERA26 @ERAkidney ja.ma/4ftcLAI
