Calcium and Sudden Cardiac Death in End‐Stage Renal Disease
Bibliographic record
Abstract
Sudden cardiac death (SCD) accounts for a quarter of all deaths in end-stage renal disease (ESRD) patients. While causative mechanisms of SCD in this high risk population remain poorly defined, interaction of the vulnerable myocardium with dialysis-related arrhythmic triggers is thought to play a major role. Recent evidence suggests that dialysis-induced derangement of calcium concentrations contributes to the increased risk of all-cause and cardiovascular mortality, vascular calcification, and SCD. Current KDIGO guidelines recommend avoiding high dialysate calcium concentrations as a precaution against adverse outcomes of increased calcium burden and vascular calcification. Conversely, low calcium concentration is also implicated in the development of SCD via increased QT dispersion and prolonged QT interval. Consequently, the optimal dialysate calcium concentration in dialysis patients remains debated and further studies are needed to establish the best strategy for managing calcium in dialysis patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
