Abstract

fetched live from OpenAlex

INTRODUCTION: A 52-year-old woman presented with iron deficiency anaemia and postprandial right lower quadrant pain. Abdominal examination was unremarkable and laboratory results showed mild anaemia (haemoglobin 11.3 g/dL). Upper and lower endoscopies did not reveal any source of bleeding. Video capsule endoscopy was performed which showed a large polypoid lesion in the mid-ileum (figure 1). Abdominal contrast enhanced CT demonstrated a heterogeneously enhancing pedunculated polyp measuring approximately 6 cm (figure 2). Retrograde double-balloon enteroscopy was performed which revealed a large pedunculated polyp with hyperplastic-like mucosa protruding from a large diverticulum located approximately 70 cm proximal to the ileocaecal valve (figure 3A). The stalk appeared to arise from the base of the diverticulum (figure 3B). A technetium-99m pertechnetate scintigraphy revealed no ectopic gastric mucosa.Figure 1Video capsule endoscopy shows a large polypoid lesion.Figure 2CT shows a heterogeneously enhancing pedunculated polyp (arrow).Figure 3Retrograde double-balloon enteroscopy images. (A) Large pedunculated polyp protruding from a large diverticulum. (B) The stalk appears to arise from the base of the diverticulum. QUESTION: What is the diagnosis?

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
