BACKGROUND: Stress plays a causal role in depression onset, perhaps via alteration of hypothalamic-pituitary-adrenal (HPA) axis functioning. HPA axis hyperactivity has been reported in depression, though inconsistently, and the nature of this relationship remains unclear, partly because cortisol measurement over time has been challenging. Development of hair cortisol assessment, a method that captures cortisol over prolonged periods of time, creates new possibilities. In this study, hair cortisol was incorporated into a prospective and longitudinal study of medical internship, stress and symptoms of depression...

BACKGROUND: Retinal microvessels provides a window to assess the microcirculation of heart and brain, and might reflect cardio- or cerebrovascular disease risk. Limited information exist on the relation between psychosocial stress and the microcirculation, even though psychosocial stress might trigger vascular diseases. This study investigates whether childhood psychosocial stress is a predictor of retinal microvasculature. METHODS: We followed-up 182 Belgian children, aged 5...

Distal hair segments collected at delivery may allow for the assessment of maternal cortisol secretion in early pregnancy, an important time window for fetal development. Therefore, an investigation of the validity of distal hair cortisol concentrations is warranted. We examined the concordance between proximal and distal hair cortisol concentrations (HCC), both representing the first trimester of pregnancy. The study population was comprised of a random sample of 97 women participating in the Pregnancy Outcomes Maternal and Infant Study, a prospective cohort study of pregnant women attending prenatal clinics in Lima, Peru...

OBJECTIVES: Chronic insomnia (CI) is a common sleep disorder linked to stress and various ubiquitous stress-related disorders (e.g. cardiovascular and mental diseases). Previous experimental studies exploring the effects of stress management in CI have confirmed that reducing stress, especially through cognitive methods, could ameliorate symptoms and repercussions of CI. In this 16-week experimental pilot study, we primarily examined the feasibility of a novel method, dubbed Pythagorean Self-Awareness Intervention (PSAI) in 30 CI patients...

Prenatal environment reportedly affects the programming of developmental trajectories in offspring and the modification of risks for later morbidity. Among the increasingly studied prenatal exposures are maternal psychological distress (PD) and altered maternal hypothalamus-pituitary-adrenal (HPA) axis functioning. Both prenatal PD and maternal short-term cortisol concentrations as markers for HPA axis activity have been linked to adverse child outcomes and it has been assumed that maternal PD affects the offspring partially via altered cortisol secretion patterns...

Women living in socioeconomically disadvantaged neighbourhoods are at heightened risk of experiencing psychological stress. Therefore, identifying potential risk factors for stress is important to support positive mental health. A growing body of research has linked sedentary behaviour with mental ill-health (e.g., depression and anxiety); however, little research has specifically investigated potential linkages between sedentary behaviour and stress. Therefore, the aim of this study was to investigate the association between common types of sedentary behaviour and objectively-measured stress (as measured by hair cortisol levels) amongst women living in socioeconomically disadvantaged neighbourhoods...

Previous research demonstrated hypoactivity of the HPA axis in children with attention-deficit/hyperactivity disorder (ADHD) or externalizing symptoms. We analyzed the predictive association between the long-term HPA axis activity and increasing symptoms of ADHD in the preschool period. The sample consisted of n = 125 4-year-old children and their families (including n = 64 children with elevated ADHD symptoms). ADHD symptoms were assessed by a structured clinical interview with the mother and by parent- and teacher-report questionnaires...

PURPOSE: To examine the effectiveness of an intervention in the workplace designed to reduce job insecurity among employees affected by organizational change. METHODS: Supervisors were randomly allocated to an intervention (IG) or waiting-list-control group (CG) and the intervention was administered over a period of 3 months, comprising six group sessions. N = 103 supervisors and their team members (mean age 41.80 ± 9.60 years, 60.19% male) provided data prior to (t0) and 3 months post-intervention (t1) by means of questionnaires and hair samples...

Using a recently developed alternative assay procedure to measure hormone levels from hair samples, we examined the relationships between testosterone, cortisol, 2D:4D ratio, overconfidence and risk taking. A total of 162 (53 male) participants provided a 3 cm sample of hair, a scanned image of their right and left hands from which we determined 2D:4D ratios, and completed measures of overconfidence and behavioral risk taking. While our sample size for males was less than ideal, our results revealed no evidence for a relationship between hair testosterone concentrations, 2D:4D ratios and risk taking...

BACKGROUND: The endogenous glucocorticosteroid cortisol (F) and its metabolite cortisone (E) are known to be involved in stress adaption and anti-inflammatory and immune regulatory effects. The ratios of F to E in the matrices serum, hair and saliva are different. The shift of this ratio by the enzyme activity of 11β-hydroxysteroid-dehydrogenase, which inactivates cortisol, was often discussed. The aim of our study was to calculate the contribution of the plasma protein binding (PPB) to this shift...

Endocannabinoids are involved in depressive and anxious symptoms and might play a role in stress-associated psychiatric disorders. While alterations in the endogenous cannabinoid system have been repeatedly found in patients with posttraumatic stress disorder (PTSD), this system has been mostly neglected in borderline personality disorder (BPD). However, there is first evidence for elevated serum levels of the endocannabinoids arachidonylethanolamide (AEA) and 2-arachidonyl-sn-glycerol (2-AG) in BPD patients compared to healthy controls and PTSD patients...

The objective of this study was to evaluate hair cortisol concentration as an indicator for stress caused by chronic lameness in dairy cows. Sixty-eight cows were scored for lameness for 4 consecutive weeks. The hair of the tail switch was clipped at the beginning of the study and regrown hair was clipped after 4 wk. Hair samples were analyzed for cortisol concentration. Animals with 2 consecutive locomotion scores ≥3 or with an overall mean score >1.5 were classified as lame. After pair matching lame and nonlame cows, considering days in milk, lactation number, and milk yield, and excluding cows with less than 20 mg hair sample for analysis, 21 lame and 21 nonlame cows were included in the analysis...

BACKGROUND: Non-classical congenital adrenal hyperplasia (NC-CAH) is a recessive autosomal disease caused by a deficiency of adrenal steroidogenesis enzymes. It must be distinguished from classical CAH, either simple virilising or salt-wasting, diagnosed during the neonatal period and responsible for potentially lethal disorders of sexual differentiation. NC-CAH presents a simpler and less specific clinical picture. Herein, we present two cases comprising twin girls consulting for diffuse hypertrichosis...

Although numerous studies have described the relationship between HPA axis dysregulation and internalizing symptoms among adolescents, research using hair cortisol concentrations in pre- and young adolescent samples has not been reported. We investigated the association of self-reported internalizing symptoms with cortisol concertration in hair among pre- and young adolescents aged 10-12 years. Forty-six boys and 39 girls supplied a hair sample of at least 3 cm in length for an analysis of this period (3 months) cortisol excretion...

OBJECTIVE: Childhood trauma has been associated with greater psychological and physical morbidity, including a greater risk of developing cardiovascular disease (CVD). This may partially reflect trauma-induced disturbances in how stress is later perceived and regulated. This study evaluated the associations of childhood trauma with perceived stress and hair cortisol concentrations (HCC) in a large sample of adults with coronary artery disease (CAD) and in non-CVD patients suffering from other non-fatal illnesses...

RATIONALE: The incidence of severe hyperandrogenism associated with masculinity in women is very low. While rare and difficult to diagnose, androgen secreting tumors should be suspected in women with hyperandrogenism and hirsutism, especially in the postmenopausal population. Herein we present one case of ovarian Leydig cell tumor (LCT) with markedly elevated serum testosterone levels and frank hirsutism. PATIENT CONCERNS: A 60-year-old woman, presented with increased hair growth and androgenic alopecia and the hormonal laboratory examination showed that she had elevated serum testosterone level and normal dehydroepiandrosterone sulfate (DHEAS), androstenedione, 17- hydroxyprogesterone, cortisol and thyroid stimulating hormone (TSH)...

Background: Physiological measures indicative of the welfare status of animals during rearing could form part of an abattoir-based animal health and welfare assessment tool. A total of 66 pigs were used in this study, the aim of which was to assess how serum concentrations of haptoglobin (Hp) and C-reactive protein (CRP) (assessed in 51 pigs), and hair concentrations of cortisol (assessed in 65 pigs), measured at or close to slaughter, reflected welfare-related indicators recorded from the animal during its lifetime...

OBJECTIVE: To evaluate relationships between hair cortisol levels and perceived stress in mothers who deliver preterm and term. We hypothesized that the rate of change in cortisol levels would be greater in the preterm delivery group. METHODS: This preliminary study compared hair cortisol levels and Perceived Stress Scale (PSS) scores in predominately Caucasian mothers who delivered preterm ( n = 22) and term ( n = 30). We collected PSS and hair samples of ≥10 cm in length from mothers after delivery...

Although testosterone is associated with aggression in the popular imagination, previous research on the links between testosterone and human aggression has been inconsistent. This inconsistency might be because testosterone's effects on aggression depend on other moderators. In a large adolescent sample ( N = 984, of whom 460 provided hair samples), we examined associations between aggression and salivary testosterone, hair testosterone, and hair cortisol. Callous-unemotional traits, parental monitoring, and peer environment were examined as potential moderators of hormone-behavior associations...

Exposure to stressful environments in early childhood can cause a toxic stress response and lead to poor health outcomes, including obesity, cardiac disease, diabetes, and mental illness. In animals and maltreated children, the presence of a nurturing caregiver can buffer against the physiological disruptions associated with a toxic stress response; however, the specific caregiver and parenting characteristics that best promote a protective relationship in humans remain largely unexplored, particularly in families living in high-risk environments...
