Abstract
BACKGROUND AND OBJECTIVES: By studying cardiometabolic risk factors in children born after maternal biliopancreatic diversion bariatric surgery (AMS) compared with those in children born before maternal surgery (BMS), we tested the hypothesis that significant maternal weight loss may modify obesity-related factors transmitted via the intrauterine environment. DESIGN: Anthropometry and fasting blood levels were studied in 49 mothers who had lost 36 +/- 1.8% body weight sustained for 12 +/- 0.8 yr and their 111 children (54 BMS and 57 AMS) aged 2.5-26 yr. RESULTS: AMS children had lower birth weight (2.9 +/- 0.1 AMS vs. 3.3 +/- 0.1 kg BMS, P = 0.003) associated with a reduced prevalence of macrosomia (1.8 AMS vs. 14.8% BMS, P = 0.03) with no difference in underweight. At the time of follow-up, AMS children exhibited 3-fold lower prevalence of severe obesity (11 vs. 35%, P = 0.004), greater insulin sensitivity (homeostasis model assessment of insulin resistance index 3.4 +/- 0.3 vs. 4.8 +/- 0.5, P = 0.02), improved lipid profile (cholesterol/high-density lipoprotein cholesterol 2.96 +/- 0.11 vs 3.40 +/- 0.18, P = 0.03; high-density lipoprotein cholesterol 1.50 +/- 0.05 vs. 1.35 +/- 0.05 mmol/liter, P = 0.04), lower C-reactive protein (0.88 +/- 0.17 vs. 2.00 +/- 0.34 microg/ml, P = 0.004), and leptin (11.5 +/- 1.5 vs.19.7 +/- 2.5 ng/ml, P = 0.005) and increased ghrelin (1.28 +/- 0.06 vs.1.03 +/- 0.06 ng/ml, P = 0.005) than BMS offspring (AMS vs. BMS, respectively, for all). CONCLUSIONS: This unique study of children aged 2.5-26 yr born before and after maternal antiobesity surgery demonstrated improvements in cardiometabolic markers sustained into adolescence, attributable to an improved intrauterine environment.

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
