8/ Future trials must fix the usual pitfalls: 🚩 Phenotype enrichment (LVH, high K gradient, volume overload) 🚩 Blinded adjudication 🚩Explicit competing-risk modeling 🚩Patient burden metrics #Nephsky

Cristina Popa @nephroseeker.medsky.social · 03/10/2026
7/ Longer/ frequent dialysis reduces UF stress and smooths electrolytes. But hard CV outcomes remain scarce. Trials are often underpowered, single-center, and ignore competing risks like transplant or withdrawal.

Cristina Popa @nephroseeker.medsky.social · 03/10/2026
6/ Incremental dialysis may “preserve RRF,” but current evidence is observational, biased, and non‑adjudicated. Healthier patients are selected, not randomized. CV benefit is unproven. Only high‑RRF incident patients with strict monitoring fit the strategy

Cristina Popa @nephroseeker.medsky.social · 03/10/2026
5/ Dialysate sodium can be seen as a CV prescription, but current evidence is shaky. Trials are small, underpowered, with non-adjudicated endpoints and inconsistent CMR-LV mass results. ⬇️sodium reduces IDWG/BP yet ⬆️ hypotension. Most studies ignore competing risks+ antihypertensive confounding

3/ HDx clears larger middle molecules, yet no cardiovascular outcome benefit. Neutral PWV, neutral echo, and rising CAC in HDx. Biology doesn't guarantee outcomes. 🎯Phenotype-enriched, adjudicated trials needed
120
Cristina Popa @nephroseeker.medsky.social · 03/10/2026
2/ High-volume HDF shows the strongest survival signal - but we must stay critical. Prior trials had center effects, adherence bias, and achieved-dose confounding. CONVINCE helps, but the mechanism remains opaque www.nephjc.com/news/convince

Dialysis adequacy MUST move beyond urea kinetics, and some of us have stated this for years. 🫀The dominant threat is cardiovascular stress: volumes, electrolytes, arrhythmia, LV load, inflammation... Kt/V is not enough #Nephsky academic.oup.com/ndt/advance-...

1/ HELLP syndrome is usually lumped with #preeclampsia as “the same disease”. This nationwide French study (CONCEPTION) shows that isolated PE (iPE) & PE-HELLP actually diverge in risk factors AND outcomes Why does it matter?

Cristina Popa @nephroseeker.medsky.social · 17/09/2026
Preeclampsia and PE-HELLP are often grouped as the same disease, but are they? New nationwide French data from CONCEPTION show distinct risk factors and outcomes, raising a key question: do they carry the same long-term cardiovascular and kidney risk? #Nephsky
