Serum adropin is unaltered in adolescents with histology‐confirmed steatotic liver disease
Bibliographic record
Abstract
OBJECTIVES: Metabolic dysfunction-associated steatotic liver disease (MASLD) in adolescents is increasing. Adropin is a liver-derived peptide involved in glucose and lipid homeostasis that was shown to be reduced in adults with metabolic disorders and cardiovascular disease (CVD). Serum adropin may also be higher in young men than women. A prior study reported that serum adropin was reduced in adolescents with MASLD, but the relationship between liver histology and CVD risk factors was not reported. We tested the hypotheses that adropin is (1) reduced in adolescents with MASLD compared to adolescents with obesity (Ob) or normal weight (NW) without MASLD, (2) correlated with blood pressure (BP), arterial stiffness, and liver histopathology, and (3) higher in boys than girls. METHODS: Serum adropin was measured in 47 patients with MASLD, and 27 and 29 control participants with Ob or NW, respectively. RESULTS: Adropin was not reduced but was instead 5% and 20% higher (p > 0.42) in the MASLD compared to the Ob and NW groups, respectively. Adropin concentration was not correlated with arterial stiffness or BP. Adropin was 20% higher in boys than girls in the entire study cohort (p = 0.034). This difference was evident in the Ob group (p = 0.018), but not in the NW (p = 0.537) or the MASLD (p = 0.893) groups. Adropin was positively correlated with age within the MASLD group only (r = 0.46, p < 0.001). CONCLUSION: Serum adropin was not reduced in adolescents with Ob or MASLD as reported previously. The positive relationship between age and adropin in adolescents with MASLD requires further examination.

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.
