Do functional gut parameters predict enteral autonomy and chronic cholestasis in pediatric intestinal failure?
Bibliographic record
Abstract
BACKGROUND & AIMS: Parenteral nutrition (PN) dependency in patients with intestinal failure (IF) can lead to complications including liver disease. Therefore, IF management strives to wean patients off PN. In adult IF, chronic cholestasis is predicted by the functional gut parameters citrulline (CIT) and enteroendocrine fibroblast growth factor 19 (FGF19), which inhibits hepatic bile salt synthesis. We investigated 1) whether CIT, FGF19 and a marker for enterocyte damage (urinary intestinal fatty acid-binding protein (I-FABP)) are associated with enteral autonomy within 60 days after intestinal surgery in neonates, and 2) the longitudinal patterns of CIT, FGF19, total bile salts and C4 (marker for bile salt synthesis) in subgroups of children on long-term PN (short bowel syndrome (SBS) and functional IF). METHODS: A prospective two-center cohort study, including 1) neonates with PN-need after intestinal surgery and 2) children (aged <18y) with >6 months PN-dependency. CIT, FGF19, and I-FABP were measured post-surgery in neonates. CIT, FGF19, total bile salts and C4 were assessed on inclusion in children with long-term PN-dependency. Associations were analyzed using Cox regression models. Longitudinal patterns were analyzed using linear mixed-effects models. RESULTS: Of 50 neonates, 52 % reached enteral autonomy. Residual small bowel length <75 cm (hazard ratio 0.23, p = 0.046), but not CIT, FGF19 or I-FABP concentrations, was negatively associated with 60-day enteral autonomy. Children with SBS (n = 20) had dysregulated bile salt synthesis with lower FGF19 (24.4 vs 108.8 pg/mL, p = 0.004) and higher C4 concentrations (110.3 vs 30.9 pg/mL, p = 0.024) than children with functional IF (n = 20). In children with long-term PN, CIT concentration significantly increased with decreasing PN-dependency and total bile salt concentration significantly increased with increasing PN-duration. CONCLUSION: Functional gut biomarkers provided no additional value in predicting enteral autonomy in neonates post-intestinal surgery over residual small bowel length. In children on long-term PN, enhanced bile salt synthesis was observed in those with SBS.

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.
