Bioprosthetic Valve <i>Streptococcus bovis</i> Endocarditis Secondary to Colon Cancer Presenting with a Lacunar Stroke
Bibliographic record
Abstract
Background:Streptococcus bovis endocarditis is an uncommon but reported complication of colon cancer. Studies show that approximately 50% of patients with S. bovis infection have underlying colonic neoplasm. Case Presentation: An 82-year-old woman presented to the hospital with a lacunar stroke resulting from S. bovis endocarditis of her bioprosthetic aortic valve, ultimately leading to the diagnosis of colonic malignant disease. The patient's neurologic deficits resolved and she completed a course of intravenous antibiotics followed by a successful right hemicolectomy to remove the colonic neoplasm. We review recent literature on the association between S. bovis endocarditis and colon cancer and discuss the implications for the clinical management of this condition. Conclusion: Because of the high rate of association between S. bovis infection and colonic neoplasms, the presence of S. bovis bacteremia should prompt a work-up for occult malignant disease by colonoscopy.

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.
