Long-Term Clinical Behavior of Jejunoileal Involvement in Crohn’s Disease
Bibliographic record
Abstract
Diffuse and extensive jejunoileal Crohn's disease is an uncommon entity. In 39 patients, including 21 males and 18 females, followed for a mean duration of over 16 years between 1979 and 2004, the extent of disease was defined and disease behaviour characterized. Over 80% of patients had concomitant colonic and/or gastroduodenal involvement with Crohn's disease, suggesting that this entity may represent a specific clinical phenotype of extensive disease localization. Classification of Crohn's disease behaviour using the Vienna classification schema revealed that virtually all patients in this study suffered from intestinal stricture formation or penetrating disease complications. Moreover, pharmacological therapies with corticosteroids and immunosuppressant drugs were rarely successful, with virtually all patients requiring at least one, and usually multiple, intestinal resections. Finally, most patients required long-term nutritional support, often with home parenteral nutrition. New treatments are required, possibly defined on the basis of their effectiveness in reducing the severity and extent of intestinal disease, rather than more conventional statistically driven reductions in disease activity indexes.

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.
