Abstract
With the growing number of reports that daily hemodialysis (DHD) improves clinical outcomes and quality of life, there has been increased interest in the effects of more frequent venipunctures on blood accesses. Since 1996, we have converted 30 patients (27 in-center, 3 home) from conventional 3/week dialysis to short, daily, 6/week dialysis (sDHD). Twenty-five patients started for medical indications. End-stage renal disease (ESRD) causes were diabetes mellitus (in 7), hypertension (6), glomerulonephritis (8), hereditary nephritis (2), and other (7). Mean (±SD) age was 57 ± 16 years. Patients had an average of 3.8 major comorbidities in addition to ESRD. Thirty patients were followed on sDHD for 388 patient-months: 9 patients died after 4.2 ± 6.7 months, 3 were transplanted at 5.4 ± 2.2 months, and 3 were disenrolled at 9.3 ± 10.5 months. Fifteen patients remain on sDHD at 20.4 ± 14.1 months. Access problems for the 12 months prior to sDHD were compared to those that occurred while the patient was on sDHD. Problems were tracked by access type. There were 40 different accesses in 30 patients with a cumulative 28.07 access-years pre-DHD; 24 of these accesses were artificial bridge grafts (ABG) of either polytetrafluoroethylene or bovine material. There were 27 access problems pre-DHD, or 0.962 problems per access-year. On sDHD these same 30 patients had 41 accesses for 34.44 access-years; 23 of these were ABGs. There were 31 access problems or 0.900 problems per access-year. There were no significant differences in access problems comparing pre-DHD with on-sDHD, either in aggregate or when analyzed by access type. After 39 months of observation, there does not appear to be an increase in blood access problems when patients are converted from conventional dialysis to sDHD.

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.
