Effects of Labor on Plasma Dehydroepiandrosterone Sulfate and Cortisol
Bibliographic record
Abstract
Maternal and cord plasma dehydroepiandrosterone sulfate (DHAS) and cortisol were measured before cesarean section, during syntocinon induced labor, and at delivery after spontaneous or induced labor. The mean maternal plasma DHAS was significantly lower in cesarean sections than in spontaneous labor, and raised significantly by induction of labor. The cord plasma DHAS was not significantly different in cesarean, spontaneous or induced labor. In cesarean section, the cord plasma DHAS was higher than maternal DHAS, but they were not different during spontaneous or induced labor. Maternal plasma cortisol increases significantly during spontaneous or induced labor. During prelabor, the increase in maternal DHAS without a change in plasma cortisol suggest, at least, a change in the metabolism of maternal DHAS. During labor, the increase in plasma concentrations of both compounds indicates a change in the metabolism of cortisol and DHAS.

How this classification was reachedexpand
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.
