Acute post-transplant oxalate nephropathy: A case report and review of the literature
Bibliographic record
Abstract
Calcium oxalate deposition in the kidney allograft remains an underappreciated cause of acute graft dysfunction. Diagnoses such as acute rejection, infection, hydronephrosis, and fluid collections are more immediately considered in the early post-transplant period. Risk factors include hyperoxaluria due to chronic fat malabsorption (post gastric bypass, inflammatory bowel disease), a diet rich in salt or animal protein, vitamin C ingestion, volume depletion, diabetes, and delayed graft function. We present the case of a patient who developed acute kidney injury secondary to oxalate nephropathy at 3 months post-transplant. Renal function improved with medical management, including volume repletion, calcium carbonate, and potassium citrate, without the need for hemodialysis. As more dialysis patients with morbid obesity requiring bariatric surgery, diabetes, and metabolic syndrome are being considered for renal transplantation, this entity merits more careful attention both prior to and after 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.
