Abstract

fetched live from OpenAlex

Pseudopolyps are benign lesions without malignant potential and typically do not require biopsy or excision. We describe a 68-year-old man with ulcerative colitis found to have multiple large bridging pseudopolyps. Repeated colonoscopies and extensive biopsies revealed a large ulcerated lesion previously hidden within the pseudopolyps. The pathology of the lesion was consistent with a low-grade adenocarcinoma with invasion into the muscularis propria. This demonstrates that large pseudopolyps, although benign, can obscure other lesions with malignant potential. Therefore, in addition to careful inspection, healthcare providers must perform periodic surveillance colonoscopies and offer surgical resection to patients with giant pseudopolyposis.

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.
