Prognostic factors for short‐term survival of cats that experienced postattenuation neurologic signs after surgical attenuation of single congenital portosystemic shunts
Bibliographic record
Abstract
OBJECTIVE: To report 30-day survival of cats that experienced postattenuation neurologic signs (PANS) after surgical attenuation of a single congenital portosystemic shunt (cPSS), and to investigate prognostic factors for short-term survival. STUDY DESIGN: Multi-institutional retrospective study. SAMPLE POPULATION: A total of 59 cats with cPSS that experienced PANS. METHODS: The medical records of 10 institutions were retrospectively reviewed to identify cats that underwent cPSS attenuation from January 1, 2010 through June 30, 2023 and developed PANS within 7 days postoperatively. Exclusion criteria were cats with arteriovenous malformation and cats lost-to-follow-up prior to 30 days. Logistic regression identified factors associated with 30-day survival. Odds Ratios (OR) and 95% CIs were calculated. RESULTS: A total of 46 (78.0%) PANS-affected cats survived to 30 days. A total of 13 (50.0%) of 26 cats that experienced postattenuation seizures (PAS) survived to 30 days, with most non-surviving cats experiencing generalized PAS. Cats that experienced PAS (p < .01, OR: 0.015, 95% CI: <0.001-0.281) and treatment of PANS with propofol (p < .01, OR: 0.112, 95% CI: 0.022-0.569) were associated with decreased odds of 30-day survival. CONCLUSION: Most cats that experienced PANS survived to 30 days; however, short-term survival rate was worse for cats that experienced PAS. CLINICAL SIGNIFICANCE: The prognosis for cats that experience PANS is generally good but experiencing PAS and requiring treatment with propofol are negative prognostic factors.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
