Use of pericardial patch graft reconstruction of the right atrium for treatment of hemangiosarcoma in a dog
Bibliographic record
Abstract
A n 8-year-old 66-lb (30-kg) sexually intact male Golden Retriever was evaluated by the Veterinary Teaching Hospital at the University of Guelph for weakness, collapse, and dyspnea of 12 hours' duration.Physical examination revealed the dog was weak and unable to walk.The dog was moderately dehydrated (7%), tachycardic (180 beats/min), tachypneic (60 breaths/min), and had weak peripheral pulses and muffled heart sounds.Results of a CBC revealed mild anemia (Hct, 31%; reference range, 38 to 57%), mild hypoproteinemia (48 g/L; reference range, 55 to 76 g/L), and changes consistent with a stress leukogram.Results of biochemical analysis and urinalysis were not notable.Ventricular tachycardia was confirmed electrocardiographically; heart rate varied between 180 and 200 beats/min.Radiography of the thorax revealed mild cardiomegaly, and there was decreased radiographic detail on views of the abdomen.Abdominal ultrasonography revealed hepatic venous congestion and abdominal effusion.Cardiac ultrasonography revealed moderate pericardial effusion, mild right and left atrial enlargement, and mild mitral regurgitation.Pericardiocentesis was performed and yielded 35 ml of sanguineous fluid.The pH of the pericardial fluid was 7.4, and cytologic evaluation revealed evidence of hemorrhage with some reactive mesothelial cells.Abdominocentesis yielded fluid consistent with ascites.Following pericardiocentesis, there was no improvement in the ventricular tachycardia.Treatment consisted of administration of lidocaine (2 mg/kg [0.9 mg/lb] of body weight, IV, followed by a constant rate infusion [30 µg/kg/min (13.6 µg/lb/min), IV]), magnesium sulfate (30 mg/kg [13.6 mg/lb], IV, during a 4hour period), and procainamide (30 µg/kg/min [13.6 µg/lb/min], IV); treatment with these drugs failed to correct the arrhythmia.Further treatment, using sotalol hydrochloride (0.7 mg/kg [0.32 mg/lb], q 12 h), an orally administered class III antiarrhythmic and β-

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.
