Abstract

fetched live from OpenAlex

Case Presentation: A 51-year-old woman presented with a >1-year history of bilateral leg edema, diarrhea, and facial flushing. Examination revealed a large abdominal mass, which CT scan confirmed to be a 15x11x13 cm ovarian mass with solid and cystic components. She underwent hysterectomy and bilateral salpingo-oophorectomy. Histopathology revealed a 17 cm ovarian dermoid cyst containing an insular carcinoid tumor. Her post-operative urinary 5-hydroxyindoleacetate (HIAA) level was 23 umol/d (normal 10-40 umol/d) and chromogranin-A level was 95 ug/L (normal <94 ug/L), but positron emission tomography (PET) scan showed lymph node metastasis, prompting initiation of lanreotide, a somatostatin analogue. A perioperative echocardiogram revealed thickened, fixed, and retracted tricuspid and pulmonic valves with severe tricuspid and pulmonary regurgitation consistent with carcinoid heart disease. The right ventricle was dilated but showed preserved systolic function. Valve intervention was considered but deferred as right heart catheterization 15 weeks after surgery showed normal right-sided pressures. A follow-up echo 8 months post resection showed unchanged pulmonary regurgitation but significant improvement in tricuspid valve mobility with a corresponding reduction in tricuspid regurgitation to a mild-to-moderate level. Discussion: Thickened and fixed tricuspid valve leaflets with significant regurgitation represents a hallmark of carcinoid heart disease that can lead to progressive right heart failure, often necessitating surgical intervention. This is a rare case of carcinoid heart disease where there was marked improvement in tricuspid valve function after surgical resection of a primary carcinoid tumor and initiation of somatostatin analog therapy. It highlights the potential for timely treatment to reverse the deleterious effects of carcinoid tumors on cardiac valves, which may ultimately spare the need for cardiac surgery.

Not 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.
