Weekly · Oct 5: Drugs for CKD and Dialysis, the Heart on Dialysis, and a Camera for Fistulas

A new lipid guideline makes reduced kidney function a reason for a statin; in 2024, before it arrived, most patients for whom kidney function is now the reason had no statin prescription. An editorial asks whether GLP-1 drugs belong in dialysis units before the trials are done. A review says dialysis adequacy should be measured by what it does for the heart, troponin turns out to be a moving target during a session, and an AI reads photos of fistulas. Five picks from the week of September 25, 2026, each with the background, what's new, the caveats and what it means on Monday. **Disclosure:** Dr. Hussein serves on the Fresenius Medical Care US Home Medical Advisory Board. Two papers in this episode have Fresenius ties: a review with coauthors affiliated with Fresenius Medical Care that rates hemodiafiltration (Fresenius makes hemodiafiltration equipment), and an AI tool from the Renal Research Institute, which authors' disclosure forms describe as a wholly owned Fresenius subsidiary. Dr. Csaba Kovesdy, author of the GLP-1 editorial, is Dr. Hussein's department chief. **Chapters** - 00:00 Cold open and running order - 01:37 Statins in CKD: under the 2026 ACC/AHA guideline, an eGFR of 15 to 60 is a statin indication, but statin prescriptions were lower at more advanced CKD stages (CJASN research letter, 2024 data) - 06:18 GLP-1 drugs on dialysis: Dr. Kovesdy's CJASN editorial on a real-world study, its design limits, and the risks of malnutrition, muscle loss and hypoglycemia - 10:17 Beyond Kt/V: an NDT review weighs dialysis strategies by their cardiovascular evidence, from hemodiafiltration to potassium and sodium tailoring - 15:21 Troponin during dialysis: a systematic review finds troponin I can rise or fall during a single session in patients without symptoms - 19:21 Fistula aneurysms and AI: a photo classifier flagged 25 of 26 advanced aneurysms in a first test against in-person exams - 23:16 Close **Papers in this episode** - Kim M, et al.

AI (Claude, by Anthropic) writes the first draft from the full text of each paper, and a separate AI check compares every number with the papers; Dr. Hussein then reviews and edits the draft before the AI hosts (ElevenLabs) voice it.
