Gastroduodenal ulceration and erosion occurs in dogs with intrahepatic portosystemic shunts prior to and following percutaneous transvenous coil embolization
Bibliographic record
Abstract
Objective: To describe the syndrome of suspected gastroduodenal ulceration/erosion (GUE) in dogs with intrahepatic portosystemic shunts (IHPSS) before and after percutaneous transvenous coil embolization (PTCE). Methods: In a multi-institutional, retrospective case series, medical records from 7 specialty hospitals were reviewed to identify dogs with IHPSS diagnosed with suspected GUE prior to or following PTCE from July 31, 2013, to August 1, 2023. Eleven client-owned dogs were divided into 2 groups based on ulcer grade as determined by the Veterinary Cooperative Oncology Group-Common Terminology Criteria for Adverse Events guidelines for gastric ulceration. Factors were evaluated for association with GUE severity. Results: At the time of GUE diagnosis, the median age and weight of dogs were 20 months (range, 2 to 48 months) and 20.9 kg (range, 6.6 to 36.5 kg). Five and 6 dogs were diagnosed with suspected GUE before and after PTCE, respectively. High- and low-grade suspected GUEs were diagnosed in 6 and 5 dogs, respectively. Common clinical signs included vomiting with or without hematemesis (n = 8), lethargy (7), and inappetence (6). Dogs were receiving omeprazole (n = 2) and a steroid (1) or NSAID (5) at the time of suspected GUE diagnosis. No dogs receiving an NSAID were concurrently being treated with omeprazole. No factors evaluated were significantly associated with increased severity of suspected GUE. Conclusions: Dogs with IHPSS experience GUE despite prophylactic medical management and treatment via PTCE. Clinical Relevance: Cautious use of medications associated with GUE should be considered in dogs with IHPSS. The pathophysiology of GUE in dogs with IHPSS remains incompletely understood.

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.
