Abstract

Objectives Indirect evidence suggests that adrenal steroid production in the human fetus may have a circadian rhythm. To assess whether there is a 24-hour rhythm of fetal cortisol in the human fetus, we investigated the relationship between fetal and maternal cortisol and cortisone concentrations in maternal, umbilical arterial, and umbilical venous blood samples over a 24-hour period.Study design Elective cesarean sections were scheduled every 2 hours around the clock in 57 term (38-41 weeks' gestation) nonlaboring pregnant women. Plasma cortisol and cortisone concentrations were measured by high-pressure liquid chromatography.Results The mean 24-hour cortisol concentration was higher in umbilical arterial than in umbilical venous blood samples, 63.6 +/- 4.6 ng/mL (SEM) versus 48.7 +/- 3.2 ng/mL, respectively (P <.05). Fetal plasma cortisol showed a rhythm in the umbilical artery (acme from noon to 4 PM ) (1-way analysis of variance and least significant difference test; P <.05) but not in the umbilical vein. Umbilical arteriovenous differences showed no net transfer of cortisol to the fetus at any time of the day and net fetal production of cortisol from 8 AM to 6 PM. There was limited transfer of cortisone to the fetus and only in the 2 AM -to-noon time interval.Conclusion These data suggest the presence of a 24-hour rhythm of fetal adrenal cortisol secretion that may be controlled by a fetal circadian pacemaker.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
