Surgical and logistical concerns for ex vivo–based perfusion strategies for “donation after circulatory death” multiorgan recovery
Bibliographic record
Abstract
Organ recovery following donation after circulatory death (DCD) has been successfully developed and refined over the past 2 decades to expand the donor pool of kidneys, livers, and lungs.1,2 Compared with donation after brain death (DBD), DCD organs are exposed to additional warm ischemia. However, aided by emerging ex vivo organ perfusion technology, encouraging results have recently been reported for DCD livers, lungs, and kidneys.3-6 This technology has recently been adopted by pioneering DCD heart transplant programs, first in Australia7 and then validated in the United Kingdom.
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 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.
