Longitudinal proneuroactive and neuroactive steroid profiles in medication-free women with, without and at-risk for perinatal depression: A liquid chromatography-tandem mass spectrometry analysis.
Neuroactive steroids (NAS) are derivatives of cholesterol or steroidal precursors made in the gonads, adrenal gland, placenta and brain. We characterized longitudinal plasma proneuroactive and NAS in healthy perinatal comparison women (HPCW), women at-risk for perinatal depression (AR-PND), and women with PND with/without comorbid anxiety. We hypothesized that AR-PND women who either did or did not go on to develop PND would have elevated NAS concentrations as compared to HPCW and that NAS would be correlated to depressive and anxiety symptoms. ⋯ To our knowledge, this study represents the largest prospective study of 5-α and 5-β reductase products of progesterone and deoxycorticosterone in HPCW and women AR-PND. Data suggest that PND is associated with both a reduction of progesterone to 5β-dihydroprogesterone, 5α-dihydroprogesterone, and allopregnanolone, and the 21-hydroxylation to deoxycorticosterone and tetrahydrodeoxycorticosterone. The shift towards 5α-dihydroprogesterone, deoxycorticosterone and tetrahydrodeoxycorticosterone was associated with a history of depression, a significant risk factor for PND.

Cortisol slopes and conflict: A spouse's perceived stress matters.
Perceived stress can lead to dysregulated cortisol patterns, including blunted peaks and flatter slopes, which are associated with increased morbidity and mortality risks. Couples' interdependence provides a prime opportunity for partners' stress to disrupt a healthy cortisol pattern. This study examined how individuals' own perceived stress and their partners' perceived stress shape cortisol levels and slopes across the day, as well as how positive and negative behaviors during conflict discussions impact associations between stress and cortisol. ⋯ On a day couples experienced conflict, having a partner with higher perceived stress is associated with dysregulated cortisol patterns, including higher levels and flatter slopes, but having a partner with lower perceived stress is linked to steeper and thus healthier cortisol declines. A partner's stress was particularly consequential for one's own cortisol when couples used more negative and fewer positive behaviors during a conflict discussion. This research adds to the growing literature on pathways connecting marital interactions to important biorhythms and health.
