Abstract
The possibility to transplant uniquely the endocrine part of the pancreas, islets of Langerhans, with the aim to recovery the endogenous insulin production in diabetic patients has always aroused attention from researches. The initial experience of this procedure however was unsatisfying especially for what concerns the long term efficacy of the islet transplantation. The exciting results obtained by the Edmonton group in 2000, 100% of insulin independence in seven diabetic patients after 1 year from the islet transplant, encouraged several centers worldwide to approach this technique. Since then several programs of islet transplantation have been launched, and important multicentric clinical trials including an high number of patients were realized. The Collaborative Islet Transplant Registry (CITR) collects data from 27 North American, 3 European and 2 Australian islet transplant centers and reported that a total of 412 patients underwent an islet transplantation in the time period between 1999-2009. The global long-term results of CITR demonstrated an insulin independence after islet transplantation in a low percentage of cases but a partial function of the graft, and consequently important advantages for the patients, in the majority of these. Actually islet transplantation is considered a valid therapeutic option only for selected patients affected by type 1 diabetes mellitus (DMT1). This limitation is a consequence of the benefit/cost ratio between improvement of the glycemic control and the necessity for transplant recipients to be treated with chronic immunosuppressive therapy which has, as well known, important side effects. These considerations and the availability of new generation basal insulin and sophisticated micro insulin pumps lead the majority of European centers to perform islet transplantation almost exclusively in combination with kidney transplant in DMT1 patients candidate (simultaneous islets-kidney transplant), or just subjected (islet after kidney transplant), to a kidney transplantation for end-stage diabetic nephropathy. These patients therefore would anyway be treated with immunosuppressive drugs. Even if the combined kidney-pancreas transplantation showed excellent results in DMT1 patients with end-stage diabetic nephropathy, the combined kidney-islet transplantation is considered a valid option in selected cases for this patient category.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
