Abstract
BACKGROUND: Parenteral omega-3 fatty acids, such as Omegaven, may benefit patients with pediatric short bowel syndrome (SBS) who develop parenteral nutrition-associated liver disease (PNALD). PATIENTS AND METHODS: Retrospective cohort describing the outcome of all 12 children with SBS and advanced PNALD who were treated with Omegaven (target omega-6 to omega-3 fatty acid ratio = 1:1 to 2:1). RESULTS: The median age was 7.5 (range 3.6-46) months, and median parenteral nutrition duration before starting Omegaven was 28.4 (range 15.3-55.3) weeks. Median initial serum conjugated bilirubin was 137 (range 54-203) micromol/L (8.06 [3.18-11.94] mg/dL). Of the 12 patients, 9 had complete and sustained resolution of hyperbilirubinemia within a median of 24 (range 7-37) weeks, and all are no longer being considered for liver transplantation. Improvements in markers of hepatic inflammation as well as nutritional status also were noted in these patients. Three patients received a liver-intestine transplant while taking Omegaven. There were no complications attributable to Omegaven. CONCLUSIONS: Omegaven is associated with restoration of liver function in patients with SBS and advanced liver disease. Parenteral omega-3 fatty acids, such as Omegaven, have the potential to fundamentally alter the paradigm of neonatal SBS from one of early death or transplantation from liver failure to a more chronic disease. More children with SBS should achieve full enteral tolerance and those who do not have the capacity for intestinal adaptation should be able to survive and receive an intestinal graft when older.

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 it
