Introduction: During pregnancy, maternal cortisol levels are increased 3-fold by the third trimester. The enzyme 11β-hydroxysteroid dehydrogenase (11β-HSD, isoforms 1 and 2) regulates the balance between cortisol and cortisone levels. Perfluoroalkyl substances (PFAS) have been reported to inhibit 11β-HSD1 and more potently 11β-HSD2, which could lead to reduced levels of cortisol and more extensively cortisone.
Aim: The aim of this work is to investigate a possible effect of early pregnancy PFAS exposure on late pregnancy activity of 11β-HSD1 and 11β-HSD2 assessed by cortisol and cortisone levels in diurnal urine (dU) and blood samples.
Methods: This study is part of the prospective cohort study, Odense Child Cohort (OCC). A total of 1628 pregnant women had serum (S) concentrations of 5 PFAS (perfluorooctanoic acid [PFOA], perfluorooctane sulfonic acid [PFOS], perfluorohexane sulfonic acid [PFHxS], perfluorononanoic acid [PFNA], and perfluorodecanoic acid (PFDA)) measured in the first trimester (median gestational week, GW 11). dU cortisol and cortisone (n = 344) and S-cortisol (n = 1048) were measured in the third trimester (median GW 27).
Results: In multiple regression analyses, a 2-fold increase in S-PFOS was significantly associated with lower dU-cortisone (β = -9.1%, P < .05) and higher dU-cortisol/dU-cortisone (dU-C/C) (β = 9.3%, P < .05). In crude models, a doubling in PFOS, PFOA, PFHxS, and PFNA concentrations were associated with a significant increase in S-cortisol; however, these associations became insignificant after adjustment.
Conclusion: Early pregnancy maternal S-PFAS were inversely associated with late pregnancy dU-cortisone, indicating reduced activity of 11β-HSD2.

Obesity due to excessive body fat accumulation remains a global problem. Patients with obesity have high cortisol levels, and its dysregulation is caused by increased 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) levels. The effects and mechanism of J2H-1702, an 11β-HSD1 inhibitor, on nonalcoholic steatohepatitis (NASH) were explored.

Neonates exhibit pain responses characterized by various endocrinal changes, including alterations in cortisone and oxytocin serum levels, as well as physiological and emotional reactions. The administration of neonatal pain management leads to the normalization of endocrine hormones, including cortisone and oxytocin, which are affected by the presence of neonatal pain. Diagnosing neonatal pain is complex; however, effective management is essential.

Psychological stress has a significant impact on individuals' quality of life and health. Traditionally, psychological stress assessment relies on self-reported tools such as the Perceived Stress Scale (PSS), which are inherently subjective. This study aims to evaluate the feasibility of using wastewater-based epidemiology (WBE) to assess cortisol and cortisone as biomarkers for psychological stress.
