Islets Isolated From Donors With Elevated HbA1c Can Be Successfully Transplanted
Bibliographic record
Abstract
Clinical islet transplantation is limited by the availability of donor organs. We report two cases where islets were isolated from donors with elevated HbA1c (6.3% and 7.9%). Islet isolation yield was adequate in both cases (521,350 and 497,472 islet equivalents, respectively). Islet graft analyses revealed a decreased proportion of beta cells (21.6%) and an increase in alpha cells (51.0%) in the donor with the higher HbA1c, although graft characteristics of the other donor were similar to donors with normal HbA1c. Both islet preparations were transplanted into type 1 diabetes recipients with brittle diabetes. One recipient has remained insulin independent for 4 years to date with good glycemic control. The other recipient who received islets from the donor with the higher HbA1c had a 56% reduction in insulin requirement after transplant. Pancreases from donors with mild hyperglycemia may be a source of islets that could be considered for clinical islet transplantation.

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.
