A rare fatal complication of bleeding immediately following polytetrafluoroethylene arteriovenous grafting in a lady with Goodpasture syndrome
Bibliographic record
Abstract
We report a 28-year-old female with no history of allergies and recent onset of Goodpasture syndrome who developed life-threatening bleeding immediately after placement of a polytetrafluoroethylene (PTFE) graft as an access for hemodialysis in the left upper limb by an experienced vascular surgeon. In spite of transfusing fresh frozen plasma, packed cells and cryoprecipitate, her prothrombin time (PT), activated partial thromboplastin time and international normalized ratio became progressively worse which were normal at the beginning of the surgery. She had profound hypotension and succumbed within 8 hours. We suspect a rare phenomenon of the interaction of her blood with the PTFE graft causing activation of bleeding and coagulation factors leading to disseminated intravascular coagulation (DIC).
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.
