Older adolescent and young adults (OAYA) with type 1 diabetes (T1D) living in contexts of socio-economic disadvantage (SED) suffer disproportionately from poor glycemic control and related health complications. Although SED may convey a variety of risks, it may exacerbate diabetes-related stress levels, which in turn may account for observed disparities in health outcomes. The primary goal of the present study was to investigate the relationship between subjective SED, diabetes-related perceived stress, and diurnal cortisol secretion in urban OAYA with T1D...

Salivary glands produce a bicarbonate-rich fluid containing digestive and protective proteins and other components to be delivered into the gastrointestinal tract. Its function is under strict control of the autonomic nervous system. Salivary electrolyte and fluid secretion is primarily controlled by parasympathetic activity, while protein secretion is primaily triggered by sympathetic stimulation. Stress activates the hypothalamic - pituitary - adrenal axis. The peripheral limb of this axis is the efferent sympathetic/adrenomedullary system...

Given the central role of stress-responsive neurophysiology in mental and physical health, it is important to understand how particular patterns of stress responsivity may become entrained by the early caregiving environment. In this study we investigated links between maternal depression and anxiety symptom profiles and within-infant development of hypothalamic-pituitary-adrenal (HPA) axis responses from 6 to 18 months of life. Associations with infant cognitive and social-emotional development were also tested to gauge the adjustment implications of HPA response trajectories...

PURPOSE: Low resting metabolic rate (RMR) and high carbohydrate reliance at rest are associated with weight gain, but are highly variable in obese individuals. This study determined the relationship of total and segmental body composition and adiposity hormones with RMR and respiratory exchange ratio (RER) in overweight and obese adults. METHODS: In 49 men (n = 23) and premenopausal women (n = 26) [mean ± SD; age = 35.0 ± 8.9 years; body mass index (BMI) = 33...

[Purpose] Hormone replacement therapy has been reported to be effective for alleviating menopausal symptoms, its side effects have been a concern. Therefore, it is necessary to investigate methods that could alleviate menopausal symptoms but with fewer side effects. Few previous reports have investigated the effects of simplified, viable manual lymph drainage, particularly the effects of one-time therapy on physiologically active substances and other variables. Effects of one-time simplified lymph drainage performed at salon A were investigated in females with any type of menopausal symptoms, such as edema or a sense of fatigue...

INTRODUCTION: Inflammation is drawing attention as pathway between psychosocial stress and health, and basal HPA axis activity has been suggested to exert a consistent regulatory influence on peripheral inflammation. Here we studied the relationship between basal HPA axis activity and inflammatory and HPA axis acute stress reactivity. METHODS: We recruited 48 healthy individuals and collected saliva for diurnal cortisol sampling at 6 points. Participants were previously exposed to the Trier Social Stress Test (TSST) on two consecutive days...

OBJECTIVES: To investigate possible relationships among oral mucosal epithelial MUC1 expression, salivary female gonadal hormones and stress markers, and clinical characteristics in patients with burning mouth syndrome (BMS). DESIGN: Thirty post-menopausal female patients with BMS (60.0±5.0 years) were included. Clinical and psychological evaluations were performed and the expression level of oral mucosal epithelial MUC1 was analyzed. The levels of cortisol, dehydroepiandrosterone (DHEA), 17β-estradiol, progesterone, chromogranin A, and blood contamination were determined from unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) samples...

OBJECTIVES: A social action theory of chronic stress proposes that agonistic striving (seeking to influence or control others) impairs cardiovascular health by magnifying the impact of high adversity-induced cortisol levels on blood pressure. We tested three predictions of social action theory: (1) the social action theory taxonomy of regulatory strivings characterizes young adults from high-adversity neighborhoods; (2) high cortisol levels predict high blood pressure more reliably in the subgroup with the agonistic striving profile than in subgroups with other profiles; (3) the association of higher cortisol and higher blood pressure with agonistic striving is not explained by negative affect (depressive symptoms/dysphoria, anger, hostility)...

Saliva is an easily accessible sample and offers practical and noninvasive biomarker solutions as an alternative to blood and urine-based diagnostics. Saliva contains a plethora of biomolecules such as nucleic acids, hormones, proteins, and electrolytes. On the other hand, little is known on the extent to which the biomolecules in saliva vary over time within a given person. This baseline information is crucial for future development of robust saliva-based diagnostics. We have collected unstimulated whole mouth saliva from 20 healthy young men at four times during the day, including before and after a meal...

BACKGROUND It has been unclear whether relatively high cortisol and cortisone levels are related to overweight in childhood, parental body mass index (BMI), and family dietary habits. The aim of this study was to compare cortisol and cortisone levels in urine and saliva from overweight and normal children, as well as correlations between children's BMI, parental BMI and family dietary behavior questionnaire score (QS). MATERIAL AND METHODS We analyzed the data from 52 overweight children and 53 age- and sex-matched normal-weight children aged 4-5 years...

Combative sport is one of the most physically intense forms of exercise, yet the effect of recovery interventions has been largely unexplored. We investigated the effect of cold water immersion on structural, inflammatory and physiological stress biomarkers following a mixed martial arts contest preparation training session in comparison to passive recovery. Semi-professional MMA competitors (n=15) were randomly assigned to a cold water immersion (15 min at 10°C) or passive recovery protocol (ambient air) completed immediately following a contest preparation training session...

Immobilization and hypoxemia are conditions often seen in patients suffering from severe heart insufficiency or primary pulmonary diseases (e.g. fibrosis, emphysema). In future planned long-duration and exploration class space missions (including habitats on the moon and Mars), healthy individuals will encounter such a combination of reduced physical activity and oxygen tension by way of technical reasons and the reduced gravitational forces. These overall unconventional extraterrestrial conditions can result in yet unknown consequences for the regulation of stress-permissive, psycho-neuroendocrine responses, which warrant appropriate measures in order to mitigate foreseeable risks...

OBJECTIVE: Glucocorticoids are released in response to stress and alter cognition and brain function through both rapid, nongenomic and slow, genomic mechanisms. Administration of glucocorticoids in the form of hydrocortisone enhances aspects of learning and memory in individuals with PTSD, but impairs these abilities in healthy individuals. We examine the time-dependent effects of glucocorticoids on cognition in HIV-infected men. METHODS: In a double-blind, placebo-controlled, cross-over study, we examined the time-dependent effects of a single low dose of hydrocortisone (10mg; LDH) on cognition in 45 HIV-infected men...

OBJECTIVE: Posttraumatic stress symptoms (PTSS) are commonly associated with impairments in extinguishing fear to signals previously associated with danger, and also with inhibiting fear to safety signals. Previous studies indicate that PTSS are associated with low cortisol activity, and cortisol is shown to facilitate fear extinction. Few studies have examined the influence of cortisol reactivity on fear extinction in PTSS. METHOD: We used a standardized fear conditioning and extinction paradigm to investigate the relationship between fear extinction and endogenous salivary cortisol activity in participants with high PTSS (n=18), trauma-exposed controls (n=33), and non-trauma-exposed controls (n=27)...

Overexposure to maternal cortisol in utero has been associated with lower birth weight of offspring. In order to regulate fetal exposure to this hormone, placental expression of 11-β-hydroxysteroid dehydrogenase-2, an enzyme that converts active cortisol to inactive cortisone, increases across pregnancy. Because of this increase in 11-βHSD2 activity, measuring maternal cortisol in isolation may not reflect actual fetal exposure to the hormone. Previous work by Hellgren et al. (2016) has shown that maternal serum cortisone:cortisol ratio was a better predictor of offspring birth weight than cortisol measured in isolation...

OBJECTIVES: Childhood abuse has been associated with depression in later life. This may be related to hypothalamic-pituitary-adrenal (HPA) axis functioning. Therefore we aimed to examine the impact of childhood abuse and its interaction with depression on cortisol levels in older adults. METHODS: Data from 418 participants (mean age 70.8 years) in the Netherlands Study of Depression in Older Persons (NESDO) were used; 187 participants experienced childhood abuse; 309 participants had a diagnosis of depression...

INTRODUCTION: Various behaviors, such as physical activity and sleep, have been shown to have stress-reducing and beneficial effects on wellbeing. In contrast, the rewarding effects of eating and drinking have rarely been investigated, particularly using ecologically valid approaches, and little is known about mediating mechanisms on the biological level. METHODS: Seventy-seven healthy young adults completed items on eating and drinking as well as momentary wellbeing (measured by mood, energy, tension, stress and fatigue levels) on an iPod touch 5×/day for 4 consecutive days...

BACKGROUND: Gender-specific differences in hypothalamus-pituitary-adrenal (HPA) axis activity have been postulated to emerge during puberty. We conducted a systematic review and meta-analysis to test the hypothesis that gender-specific differences in HPA axis activity are already present in childhood. METHODS: From inception to January 2016, PubMed and EMBASE.com were searched for studies that assessed non-stimulated cortisol in serum or saliva or cortisol in 24-h urine in healthy males and females aged ≤18 years...

RATIONALE: Although cortisol alterations have been associated with posttraumatic stress disorder (PTSD) and PTSD symptoms (PTSS), the direction of association is mixed. Cortisol which is measured in blood, saliva, or urine is subject to transient factors that may confound results. Recent advances in cortisol sampling techniques provide novel opportunities to address these inconsistencies. Hair cortisol sampling is a non-invasive method for the retrospective assessment of long-term integrated cortisol, yet its utility at predicting PTSS has not been assessed in acute injury victims...
