P116 RIPK3 - a new marker for assessment of ulcerative colitis severity
Bibliographic record
Abstract
Abstract Background Necroptosis is a novel form of regulated necrotic cell death that is dependent on Receptor interacting protein kinase-3 (RIPK3). It leads to cell lysis and directly triggers inflammation. Several clinical and preclinical studies have implicated necroptosis in the etiopathogenesis of inflammatory bowel disease. Methods The aim of the study was to evaluate the expression of RIPK3 according to the activity and severity of ulcerative colitis (UC). Tissue expression of RIPK3 was determined immunohistochemically in intestinal biopsies from 85 patients with ulcerative colitis. Тo evaluate the severity and activity of UC were used the Montreal classification for disease severity (S), full Mayo score (MS) and Mayo endoscopic score (MES). Results A moderate direct correlation was found between disease severity and RIPK3 expression (r=0.354; p=0.001), with severe disease (S3) being characterized by overexpression of the marker (199.67). A moderate right-proportional relationship was also found in the analysis of RIPK3 expression and UC activity, measured by the full Mayo score (r=0.481; p<0.001). RIPK3 expression increased with increasing disease activity (p<0.001), and patients with severe disease activity (MS =11-12) had overexpression of the marker (211.71). A moderate correlation between RIPK3 expression and the degree of endoscopic activity was also found (r=0.363; p=0.001), with patients with severe endoscopic activity (MES=3) having high expression of the marker (198.27). Conclusion High expression of RIPK3 in UC patients was associated with severe disease activity assessed by the Montreal classification and full Mayo score and marked endoscopic activity.

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.
