Salivary cortisol as a biomarker in stress research.
TLDR
The present paper addresses several psychological and biological variables, which may account for such dissociations, and aims to help researchers to rate the validity and psychobiological significance of salivary cortisol as an HPAA biomarker of stress in their experiments.About:

Observing and predicting knowledge worker stress, focus and awakeness in the wild
Mauricio Soto,Chris Satterfield,Thomas Fritz,Gail C. Murphy,David C. Shepherd,Nicholas A. Kraft +5 more
TL;DR: It is found that days with high levels of stress tend to cluster, similarly as the days with low awakeness, and it is shown that machine learning models can be built from the data of a single minimally invasive device to predict stress, focus, and awakeness.

The Emotional and Behavioral Impact of Delivering Bad News to Virtual versus Real Standardized Patients: A Pilot Study
Sarah R O'Rourke,Kelly Branford,Taylor L Brooks,Lindsay T. Ives,Arjun Nagendran,Scott N. Compton +5 more
TL;DR: The results suggest that medical students may have similar emotional and behavioral responses when delivering bad news to a vSP when compared to an rSP, providing support for the continued use of vSPs in training learners to deliver bad news and other communication-based skills and to assess their performance on these tasks.

Determination, intercorrelation and intraindividual stability of five steroids in hair, saliva and urine among chinese college students.
TL;DR: Hair biomarkers showed no absolute stability, but moderate to high long-term relative stability across 12 months where interclass correlation coefficients ranged between 0.356 and 0.678, implying that the eight biomarkers in hair could retrospectively reflect their cumulative exposure in vivo.
Journal ArticleDOI
Memories of and influenced by the Trier Social Stress Test.
TL;DR: This current review summarizes the impact of acute stress on human long-term memory taking a neuroendocrine perspective and finds that the stress associated increase in activity of the sympathetic nervous system and the hypothalamus-pituitary-adrenal axis are key.
Journal ArticleDOI
Acute Stress Assessment From Excess Cortisol Secretion: Fundamentals and Perspectives.
TL;DR: The concept of stress is then related to a state of difficulty in maintaining allostasis, rather than referring to the overall body response to the situation, and the excess proportion of cortisol load is consequently proposed to scale the stress level.

Impact of gender, menstrual cycle phase, and oral contraceptives on the activity of the hypothalamus-pituitary-adrenal axis.
TL;DR: Although men seem to have a stronger hypothalamic drive in response to stressful stimulation than women, differences in salivary-free cortisol levels, at least in part, may be explained by estradiol-induced changes in corticosteroid-binding protein levels.

Free Cortisol Levels after Awakening: A Reliable Biological Marker for the Assessment of Adrenocortical Activity
Jens C. Pruessner,Oliver T. Wolf,Dirk H. Hellhammer,Angelika Buske-Kirschbaum,K. von Auer,Silke Jobst,F. Kaspers,Clemens Kirschbaum +7 more
TL;DR: Early morning cortisol levels can be a reliable biological marker for the individual's adrenocortical activity when measured repeatedly with strict reference to the time of awakening, in contrast to single assessments at fixed times.

Maternal care during infancy regulates the development of neural systems mediating the expression of fearfulness in the rat
Christian Caldji,Beth Tannenbaum,Shakti Sharma,Darlene D. Francis,Paul M. Plotsky,Michael J. Meaney +5 more
TL;DR: It is suggested that maternal care during infancy serves to "program" behavioral responses to stress in the offspring by altering the development of the neural systems that mediate fearfulness.
Journal ArticleDOI
Limbic system mechanisms of stress regulation: hypothalamo-pituitary-adrenocortical axis.
TL;DR: The influence of the limbic system on the HPA axis is likely the end result of the overall patterning of responses to given stimuli and glucocorticoids, with the magnitude of the secretory response determined with respect to the relative contributions of the various structures.

The cortisol awakening response (CAR): Facts and future directions
TL;DR: It is hypothesized that the anticipation of the upcoming day is of major relevance for the magnitude of the cortisol awakening response, and considerations are addressed concerning the exact function of the CAR.
