Abstract

fetched live from OpenAlex

A 75-year-old female presented with a 1 year history of a firm, diffusely swollen, and erythematous facial plaque. She had preceding unsuccessful investigations and treatment for angioedema. Full-skin examination revealed multiple prominent varicosities on the chest and abdomen. Superior vena cava syndrome was suspected. Solid facial edema (Morbihan's syndrome) and various infiltrates included in the differential diagnosis were ruled out with a skin biopsy. Chest computed tomography confirmed a complete superior vena cava thrombosis. Extensive workup for associated malignancy has to date been unremarkable, and as yet an underlying cause remains to be found.

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.

Not 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.
