Abstract

fetched live from OpenAlex

An 18-year-old man, working on a farm, presented with a five-year history of bloating and abdominal cramps. He denied hav-ing any diarrhea, constipation or rectal bleeding. His medical history was remarkable for a diagnosis of autism spectrum disor-der in early childhood, for which he received very little inter-vention due to the paucity of services in his rural community. There was no family history of gastrointestinal diseases. On examination, the patient was noted to be tall and thin, with a body mass index of 20 kg/m2. There were no oral mucosal lesions, cervical adenopathy or palpable abdominal masses or tenderness. At the onset of his symptoms, the patient had undergone a gastroscopy and colonoscopy which were normal. A gastroscopy repeated one year previously, however, showed a ‘mild nonspecific gastritis’, in the absence of Helicobacter pylori infection or nonsteroidal anti-inflammatory use. The patient’s symptoms actually worsened on a trial of proton pump inhib-itor; consequently, the medication was discontinued. A subse-quent small-bowel follow-through was unremarkable. The patient was then given a trial of an antispasmodic drug pinaverium bromide (Dicetel, Solvay Pharma Inc, Canada) which also did not improve his symptoms. Finally, a colonoscopy was repeated, revealing small, round centrally clearing lesions in the rectum and ascending colon consistent with focal active colitis (Figure 1), as well as lymphoid hyperplasia of the terminal ileum. Because there were no true signs of chronic gland damage or granulomata, a diagnosis of Crohn’s disease could not be made. The patient failed a trial of high-dose 5-aminosalicylic acid therapy, but improved on a tapering course of steroids.

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.
