Cortisol diurnal

Michelle Henry, Ian Louis Ross, Kevin Garth Flusk Thomas
OBJECTIVES: Cortisol plays a key role in initiating and maintaining different sleep stages. Patients with Addison's disease (AD) frequently report disrupted sleep, and their hydrocortisone medication regimes do not restore the natural diurnal rhythm of cortisol. However, few studies have investigated relations between sleep quality, especially as measured by polysomnographic equipment, and night-time cortisol concentrations in patients with AD. METHODS: We used sleep-adapted EEG to monitor a full night of sleep in 7 patients with AD and 7 healthy controls...

OBJECTIVE: Revealing one's sexual identity to others is a complex process marked by a shift in the types of stressors faced by sexual minority young adults. Such stressors influence the secretion of health-relevant hormones, including cortisol, yet how dimensions of disclosure (i.e., the degree and context) influence neuroendocrine functioning remains poorly understood. The current study examined the association between disclosure context (disclosure to family members, friends/co-workers/acquaintances, and members of religious groups) and diurnal cortisol while allowing disclosure to vary in degree (i...

Activation of the hypothalamic-pituitary-adrenal (HPA) axis (as might occur, for example, when the organism encounters a threat to allostatic balance) leads to the release of cortisol into the bloodstream and, ultimately, to altered neural functioning in particular brain regions (e.g., the prefrontal cortex (PFC)). Although previous studies suggest that exposure to acute psychosocial stress (and hence, presumably, elevation of circulating cortisol levels) enhances male performance on PFC-based working memory (WM) tasks, few studies have adequately investigated female performance on WM tasks under conditions of elevated cortisol...

Context: Understanding the biological rhythms and stress response in sick newborns is important to minimise the negative effects of intensive care. Salivary cortisol has been used as a non-invasive surrogate marker of adrenal function; however, understanding of its control variables is insufficient. Objective: This study aimed to investigate the presence of feeding-induced cortisol response and its control variables in newborns. Design, Setting and Patients: Fifty-three newborn infants, who were between 30 and 40 weeks' corrected age and were on 3-hourly regular oral/enteral feeding were recruited between January 2013 and June 2014...

Work-related stressors are known to adversely affect employees' stress physiology, including the cortisol awakening response (CAR) - or the spike in cortisol levels shortly after people wake up that aids in mobilizing energy. A flat or blunted CAR has been linked to chronic stress and burnout. This daily diary study tested the effects of a workplace intervention on employed parents' CAR. Specifically, we tested whether the effects of the intervention on CAR were moderated by the type of days (workday versus non-work day)...

BACKGROUND: Symptoms of anxiety may arise from fear of cancer recurrence and memories of traumatic experiences during treatment. This study aimed to identify changes in mental health and cortisol, a biological marker of stress, associated with oncology surveillance clinic attendance. METHODS: Adolescent and young adult (AYA) survivors of childhood cancer (aged 12-30 years, N = 46) attending a survivorship clinic were recruited. The State-Trait Anxiety Inventory, an anxiety self-rating and open answer question, and salivary cortisol collections were completed two weeks before and one day before clinic, on clinic day and two weeks after...

The hypothalamic-pituitary-adrenal (HPA) axis activity has been demonstrated as one of the physiological mechanisms underlying the long-lasting effects of peer victimization on physical and mental health. However, the mechanisms linking peer victimization to dysregulations of HPA axis activity remain inadequately understood. The present study examined the potential mediating role of emotional regulation in the association between peer victimization and HPA axis activity in a large community-based sample of 645 children affected by parental HIV (Mage  = 10...

INTRODUCTION: Antenatal depression is associated with a broad range of suboptimal outcomes in offspring, although the underlying mechanisms are not yet understood. Animal studies propose inflammation and glucocorticoids as mediators of the developmental programming effect of prenatal stress on offspring stress responses, but studies in humans are not yet at this stage. Indeed, to date no single study has examined the effects of a rigorously defined, clinically significant Major Depressive Disorder (MDD) in pregnancy on maternal antenatal inflammatory biomarkers and hypothalamic-pituitary (HPA) axis, as well as on offspring HPA axis, behavior and developmental outcomes in the first postnatal year...

This study aimed to examine the relationship between trait loneliness and diurnal rhythms of salivary cortisol. Fifty-One Chinese undergraduates provided six saliva samples on a weekday at immediately, 0.5, 3, 6, and 12 h after waking, and at bedtime. Saliva collection times were monitored using electronic devices (MEMS TrackCaps). Participants were also administered a questionnaire consisting of scales measuring, trait loneliness, depression, and demographics. Relationships between loneliness and the cortisol awakening response (CAR), diurnal slope (DS), and area under the curve with respect to ground (AUCG ) were examined using multiple regression analyses...

Rhythms can be observed at all levels of the biologic integration in humans. The observation that a biological or physiological variable shows a circadian rhythm can be explained by several multifactorial systems including external (exogenous), internal (endogenous) and psychobiological (lifestyle) mechanisms. Our body clock can be synchronized with the environment by external factors, called "synchronizers", i.e. the light-dark cycle, but it is also negatively influenced by some pathological conditions or factors, called "chronodisruptors," i...

OBJECTIVE: Exposure to sexual assault is a significant risk factor to develop post-traumatic stress disorder (PTSD) in females. The early neurobiological changes leading to the development of PTSD remain understudied and unclear in this population. METHODS: Participants were 27 adult females recruited within a month following exposure to sexual assault (T1) and 20 age-matched non-exposed controls. Among the victims, 10 participants met (PTSD+) and 15 did not meet (PTSD-) DSM-IV criteria for PTSD 6 months post-trauma (T2)...

Many older adults experience chronic age-related stressors (e.g., life regrets or health problems) that are difficult to control and can disturb cortisol regulation. Self-compassion may buffer adverse effects of these stressful experiences on diurnal cortisol secretion in older adulthood. To examine whether self-compassion could benefit older adults' cortisol secretion in the context of chronic and largely uncontrollable age-related stressors, 233 community-dwelling older adults reported their levels of self-compassion, age-related stressors (regret intensity, physical health problems, and functional disability), and relevant covariates...
