Surgical Management of Omphalophlebitis and Long Term Outcome in Calves: 39 Cases (2008–2013)
Bibliographic record
Abstract
OBJECTIVE: To describe and evaluate the surgical management of omphalophlebitis and to report the short and long term outcomes in calves. STUDY DESIGN: Retrospective case series. ANIMALS: Calves (n = 39). METHODS: Medical records (2008-2013) of calves diagnosed with omphalophlebitis and that underwent surgical correction were reviewed. Short term (hospital discharge) and long term (≥6 months after surgery) survival rates were obtained. Descriptive statistics were used to describe the population and a Fisher's exact test was used to evaluate the relationship between clinical signs, surgical management, and outcome. RESULTS: Thirty-nine calves (median age 30 days) were included in the study. Eleven calves had septic arthritis associated with omphalophlebitis and 18 had evidence of liver abscesses on ultrasound. Complete surgical en bloc resection was achieved in 18 calves and umbilical vein marsupialization was performed on the other 21 calves. Thirty-five calves were discharged from the hospital and long term followup was obtained for 30 of them. Twenty-nine animals were performing according to the owner's expectation at least 6 months after surgery (14 for marsupialization and 15 for en bloc resection). A better prognosis was detected when en bloc resection was performed (100% survival); however, when marsupialization was performed, the prognosis was good (74%; P = .05). Septic arthritis had a significant negative effect on overall survival (P < .001). CONCLUSION: The overall survival is good with both surgical options, and even calves with liver involvement and septic arthritis associated can be successfully treated with a combination of long term antibiotics and umbilical vein marsupialization.

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.
