Few studies have examined individual differences in stress reactivity during pregnancy. The current study examined whether cortisol responses to a laboratory stressor (Trier Social Stress Test; TSST) significantly differed within an ethnically diverse sample of 34 pregnant women (38% Latina, 29% African American) identified to be at low (n = 17; i.e., low depressive symptoms) versus high risk for depression (n = 17; i.e., past history of depression and/or high depressive symptoms). Women at high depression risk, particularly those with a past history of depression, showed greater cortisol responses to the TSST than women at low depression risk, controlling for gestational age, parity, and education (p = 0.03). Moreover, African American women, particularly those at high depression risk, showed blunted cortisol responses to the TSST compared to non-African American women (p = 0.02). Our results highlight risk factors for depression during pregnancy and have strong implications for reducing health disparities in this population.

Growth hormone (GH) secretion by the pituitary is regulated by stimulatory and inhibitory pathways such as growth hormone releasing hormone (GHRH) and somatostatin, respectively, being also modulated by different neurotransmitters acting at the hypothalamic/pituitary level. The pineal gland hormone melatonin regulates GH secretion in many mammals, including humans, although its role in modulating GH secretion has been debated. We describe the case of a young woman chronically taking melatonin for sleep disturbances, referring to her general practitioner for flushing that appeared just after starting melatonin intake.

Identifying proximal and multigenerational distal risk mechanisms through which adversity exposure may shape neuroendocrine dysregulation among children is critical to advancing effective preventive interventions for adversity-exposed individuals. Utilizing longitudinal data ( = 247), the current study examined maternal and offspring history of childhood maltreatment (CM) as predictors of offspring cortisol/DHEA ratios, and, in exploratory analyses, extended this longitudinally to offspring depressive symptoms in young adulthood. Youth (ages 8-13 years) initially attended a research camp, then were followed up approximately eight years later (ages 18-22 years).

Background: With the continuous development of laparoscopic techniques in recent years, laparoscopic total mesorectal excision (LapTME) and laparoscopic-assisted transanal total mesorectal excision (TaTME) have gradually become important surgical techniques for treating low-lying rectal cancer (LRC). However, there is still controversy over the efficacy and safety of these two surgical modalities in LRC treatment.
Aim: To compare the efficacy of LapTME TaTME in patients with LRC.
