Delayed ghrelin suppression following oral glucose tolerance test in children and adolescents with hypothalamic injury secondary to craniopharyngioma compared with obese controls
Bibliographic record
Abstract
Ghrelin, released from the stomach, acts at the hypothalamus and is associated with initiation of food intake. We hypothesised that patients with craniopharyngioma and hypothalamic obesity (CRHO) would have ghrelin abnormalities. Fifteen CRHO patients and 15 BMI-matched controls underwent oral glucose tolerance test with dynamic ghrelin measurement. From 0-30 minutes, ghrelin (pg/ml) decreased less (43.4 ? 38.8 vs. 70.8 ? 35.8, p < 0.05) and insulin (pmol/l) increased more (1 669.2 ? 861.7 vs. 1 049.1 ? 560.4, p = 0.04) in CRHO compared with controls, respectively. Insulin area-under-the-curve was a weak negative predictor of the 0?30 minutes ghrelin decrease (r(2) = 0.29, p = 0.02). Delayed ghrelin suppression may contribute to obesity in CRHO.

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.
