Diurnal salivary cortisol profiles are valuable indicators of adrenocortical functioning in epidemiological research and clinical practice. However, normative reference values derived from a large number of participants and across a wide age range are still missing. To fill this gap, data were compiled from 15 independently conducted field studies with a total of 104,623 salivary cortisol samples obtained from 18,698 unselected individuals (mean age: 48.3 years, age range: 0.5-98.5 years, 39% females). Besides providing a descriptive analysis of the complete dataset, we also performed mixed-effects growth curve modeling of diurnal salivary cortisol (i.e., 1-16h after awakening). Cortisol decreased significantly across the day and was influenced by both, age and sex. Intriguingly, we also found a pronounced impact of sampling season with elevated diurnal cortisol in spring and decreased levels in autumn. However, the majority of variance was accounted for by between-participant and between-study variance components. Based on these analyses, reference ranges (LC/MS-MS calibrated) for cortisol concentrations in saliva were derived for different times across the day, with more specific reference ranges generated for males and females in different age categories. This integrative summary provides important reference values on salivary cortisol to aid basic scientists and clinicians in interpreting deviations from the normal diurnal cycle.

Resilience to stressors has emerged as a major gerontological concept aiming to promote more positive outcomes for older adults. Achieving this aim relies on determining mechanisms underlying capacity to respond resiliently. This paper seeks proof of principle for the hypothesis that physical aspects of said capacity are rooted in the fitness of one's physiology governing stress response, conceptualized as a dynamical system.

Objective: For early diagnosis and inquiry into the pathophysiology of Sjögren disease (SjD), salivary secretion and component levels, and salivary glands' uptakes in sialoscintigraphy were examined, in this cross-sectional study.
Methods: Patients who visited our hospital with suspected SjD between April 2016 and March 2020 were checked for unstimulated salivary secretion and β2-microglobulin, Na+, and cortisol levels in saliva. The patients who showed any abnormal salivary test results underwent sialoscintigraphy; the uptakes in the parotid, submandibular, and thyroid glands were compared using paired t test.

Previous reports suggest that the menstrual cycle (MC) phases can impact cortisol concentrations. However, research is needed on whether the MC impacts other markers of stress and immune function. It has also been shown that some biomarkers are impacted by time of day, although differences between morning (AM) and afternoon (PM) biomarkers have not been studied over the course of the MC.

Objectives: To characterize individuals with a diminished salivary cortisol response to mental stress, assess its association with all-cause mortality, and quantify the mediating effects of the most relevant and modifiable factors to identify potential target for prevention.
Methods: Data from MIDUS II study with a 16-year follow-up, were used to categorize 1129 participants as responders or non-responders based on the existence of increase in salivary cortisol under mental stress. LASSO-logistics analysis identified the most relevant factors.

Background: Acute psychosocial stress activates the hypothalamic-pituitary-adrenal (HPA) axis and triggers the release of cortisol, a commonly used biomarker of stress reactivity. Yet only 25 % of studies have reported a correlation between cortisol and affective responses to stress. This study aimed to examine whether cortisol reactivity following an acute psychosocial stressor in the laboratory correlated with concurrent positive and negative affect in adolescents, and whether early life adversity (ELA) moderated this relationship.
