A tale of two diseases: The history of inflammatory bowel disease
Bibliographic record
Abstract
'Inflammatory bowel disease' (IBD) sounds like a straightforward term - a disease of inflammation in the bowel. However, the history of IBD reveals a story of a nefariously complex set of idiopathic conditions. IBD defies definition, in part because its pathophysiology is not completely understood. For the same reason and despite substantial advances in research, IBD also defies cure. At best, IBD can be defined as a disease of disruption - disrupted physiology, microbiology, immunology and genetics. The term 'IBD' is most often used to describe two separate conditions: ulcerative colitis (UC) and Crohn's disease (CD). This paper reviews the history of IBD, considering the ever-evolving understanding of both UC and CD. Beyond its intrinsic interest, the history of IBD exemplifies a pattern that is becoming increasingly familiar in the 21st century - the story of a chronic, incurable disease that defies the best efforts to treat it.

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.
