Abstract

fetched live from OpenAlex

OBJECTIVE The increased risk of type 2 diabetes in women with glucose intolerance in pregnancy is mediated by deterioration of their β-cell function, which occurs as early as the first year postpartum. We thus sought to identify early determinants of their declining β-cell function. RESEARCH DESIGN AND METHODS Women with recent gestational glucose intolerance (166) underwent oral glucose tolerance test at 3 and 12 months postpartum. They were stratified into those in whom β-cell function (Insulin Secretion-Sensitivity Index-2 [ISSI-2]) declined over this time (decliners; n = 92) and those in whom it did not (nondecliners; n = 74). RESULTS Between 3 and 12 months, hepatic insulin sensitivity (1/homeostasis model assessment of insulin resistance [HOMA-IR]) decreased in decliners but not in nondecliners. Over this time, the change in 1/HOMA-IR emerged as an independent predictor of the change in ISSI-2 (t = 5.5; P < 0.0001). Increased hepatic insulin sensitivity independently predicted a lower likelihood of declining β-cell function (odds ratio = 0.13 [95% CI 0.06-0.29]; P < 0.0001). CONCLUSIONS Hepatic insulin resistance is an early determinant of declining β-cell function after gestational dysglycemia.

Not 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.
