Abstract

fetched live from OpenAlex

Immune response to the human leukocyte antigens (HLA) of a donor heart, resulting in antibody-mediated rejection (AMR), remains one of the greatest challenges in current transplant medicine. Besides the risk of acute functional deterioration of the graft during rejection, there is clear evidence of induction and acceleration of the development of coronary allograft vasculopathy with recurrent or severe AMR and development of donor–specific HLA antibodies. Management guidelines and consensus statements currently have to rely on limited evidence. In this review, we illustrate some of the immune mechanisms underlying AMR, summarize the clinical impact, and discuss the therapy concepts of the recently emerging armamentarium of medical interventions. We also highlight some pitfalls for AMR-therapy protocol design and suggest a staged approach for decision-making at the occurrence of de novo donor-specific antibodies post transplant.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
