CONTEXT: Loss-of-function mutations in the POMC gene are associated with the syndrome of adrenal insufficiency, obesity and red hair. We describe here a case of POMC deficiency, in which adrenal insufficiency was not treated until the fourth year of life. One of the disease-causative POMC mutations was characterized in vitro using a new approach. CASE DESCRIPTION: A boy presented in the first year of life with red hair, growth acceleration, moderate obesity and recurrent cholestasis, which was followed by two episodes of hypoglycemia at ages of 1...

OBJECTIVE: The present study aims to explore whether hair cortisol concentration is associated with explicit stress or implicit stress in female methamphetamine addicts. METHODS: Hair samples were collected from 51 female methamphetamine addicts from inpatient addiction treatment programs. Perceived stress was assessed by both explicit and implicit measures through the Perceived Stress Scale (PSS) and the Implicit Association Test (IAT), respectively. RESULTS: The positive relationship between hair cortisol concentration with D-scores of the IAT reached statistically significant difference...

OBJECTIVES: Hair cortisol measurement has become an increasingly accepted approach in endocrinology and biopsychology. However, while in adult research hair cortisol has been proposed as a relevant biomarker for chronic stress (and its adverse consequences), studies with children are scarce. Therefore, the goal of the present exploratory study was to examine the associations between hair cortisol concentrations (HCCs), stress, and a series of health-related outcomes in a sample of Swiss first grade schoolchildren...

BACKGROUND: Evidence linking maternal psychosocial stress during pregnancy to subsequent child atopic dermatitis (AD) is growing but the definition of AD is diverse and results are inconsistent. We aimed to analyze the relationship between stress and AD using alternative methods of measurement of stress and AD. METHODS: In the Ulm SPATZ Health Study, chronic stress and symptoms of anxiety and depression were assessed by standardized self-reported questionnaires in 934 mothers of singletons following delivery in Ulm, Germany, from 04/2012-05/2013...

OBJECTIVES: The mechanisms underpinning the association between chronic stress and gut health are poorly understood. We aimed to investigate the relationship between bacterial produced short-chain fatty acids, gut barrier function, and stress measures. METHODS: A fecal sample, hair sample, and questionnaire data were collected from 113 Belgian children (8-16 years old). Biological measures of stress included hair cortisol (most proximal 3 cm) and 5-minute heart rate variability (high frequency)...

A 37-year-old female patient was hospitalized because of general fatigue and loss of axillary and pubic hair after massive bleeding at delivery of her third child. The basal levels of both plasma adrenocorticotropin hormone (ACTH) and serum cortisol were very low, 5.2 pg/mL and 1.9 μg/dL, respectively. Based on the fact that ACTH showed a low response to insulin tolerance test and a normal response to corticotropin-releasing hormone (CRH), she was diagnosed with hypothalamic adrenal insufficiency. No organic lesions were found in the hypothalamic-pituitary region by pituitary MRI and hydrocortisone therapy was instituted...

In recent times, the detection of cortisol in hair is intended to be used as an animal-based indicator for the assessment of chronic stress. However, the relationship between the ability to report average values of long-term circulating cortisol concentrations and the sensitivity to acute peaks of cortisol is still unclear. To gain insight into this relationship, 24 Holstein-Friesian bull calves under the same management conditions were used in this study. Two injections of ACTH (at D0 and D7) were administrated to twelve animals with the aim to create two acute increases of serum cortisol concentrations...

Evidence for an association between cortisol and clinical pregnancy in women undergoing In Vitro Fertilisation (IVF) is mixed with previous studies relying exclusively on short term measures of cortisol in blood, saliva, urine, and/or follicular fluid. Hair sampling allows analysis of systemic levels of cortisol over the preceding 3-6 months. The present study sought to explore the relationship between cortisol and clinical pregnancy outcome in women undergoing IVF utilising multiple indices of cortisol derived from both saliva and hair measured prior to commencing gonadotrophin treatment...

Studies investigating cortisol secretion in patients with generalized anxiety disorder (GAD) have reported heterogeneous findings. Further, current knowledge on the specificity of endocrine changes for GAD and/or comorbid major depression (MD) is limited. Hence, the current study investigated long-term integrated cortisol secretion, as indexed by hair cortisol concentrations (HCC), and experimentally-induced cortisol stress reactivity in relation to GAD, MD and their comorbidity. Carefully characterized groups of 17 GAD patients including 8 with comorbid MD (GAD-MD), 12 MD patients and 21 healthy controls were recruited...

OBJECTIVE: There is increasing evidence for weight-based discrimination against persons with obesity. This study aimed to examine the physiological impact of perceived weight discrimination on cortisol in hair, an indicator of chronic stress exposure. METHODS: Data were from 563 nonsmoking individuals with obesity (body mass index, BMI ≥30 kg/m(2) ) participating in the English Longitudinal Study of Ageing. Experiences of discrimination were reported via questionnaire, and hair cortisol concentrations were determined from the scalp-nearest 2-cm hair segment...

BACKGROUND: The chronic consequences of intimate partner violence (IPV) on HPA activation are a topic of debate. The current study investigated hair cortisol concentrations in female victims of IPV and their children. METHODS: A total of 52 mother-child dyads were divided into two groups depending on exposure to IPV: IPV group (n=27 dyads) and control group (n=25 dyads). Hair cortisol concentration was measured in 1-cm-long hair strands, representing 30days of exposure before assessment...

In a randomized controlled trial, we investigated the effects of karate versus a mindfulness-based stress reduction (MBSR) intervention on well-being and cognitive functioning in older adults. Fifty-five adults (52-81 years old) participated in twice-weekly karate versus MBSR sessions or no training for 8 weeks. In pre- and postassessments, subjective well-being, health, cognitive functioning, and chronic stress were measured. Preassessment hair cortisol served as physiological stress marker. The results showed an improvement for the karate group, but not the MBSR and control group, in subjective mental health and anxiety as well as cognitive processing speed...

Most research into 3,4-methylenedioxymethamphetamine (MDMA) has debated its psychobiological effects in relation to neurotransmission. This article debates the contributory roles of the neurohormones oxytocin and cortisol for their psychobiological effects in humans. The empirical literature on these neurohormones is reviewed and suggestions for future research outlined. Acute MDMA or 'ecstasy' can generate increased levels of oxytocin and cortisol, and these neurohormonal changes may be important for its mood-enhancing and energy-activation effects in humans...

BACKGROUND: Whereas childhood adversity (CA) and the hypothalamus-pituitary-adrenal (HPA) axis have been suggested to play a major role in the etiology of non-suicidal self-injury (NSSI), no study has thus far investigated both its associations and interactions with adolescent NSSI. METHOD: We investigated CA (antipathy, neglect, physical, psychological, and sexual abuse) and indices of HPA axis activity (salivary and hair cortisol) in a clinical sample of 26 adolescents engaging in NSSI and 26 age- and gender-matched healthy controls (HC)...

BACKGROUND: Previous studies have suggested a direct association between hair cortisol concentration (HCC) and Body Mass Index (BMI), as well as other adiposity measures. However, these studies have mostly been conducted among adult populations. OBJECTIVE: To examine the association between HCC and different measures of adiposity among a selected group of children predisposed to obesity and their parents. METHODS: We conducted a cross-sectional study based on 363 children and their parents (301 mothers and 231 fathers) participating in the "Healthy Start" study...

Cortisol is a well-known glucocorticoid that can be used as a biomarker of hypothalamic-pituitary-adrenocortical activity. To explore basal cortisol physiology during pregnancy and infancy in Macaca nemestrina monkeys, hair was collected from a convenience sample of 22 healthy mother-infant dyads. Adult females were housed in pairs as part of a small breeding colony at the Washington National Primate Research Center and infants were reared in a specialized nursery. Maternal samples were collected from females during a pregnancy-detection ultrasound and immediately following labor and delivery...

INTRODUCTION: Functional somatic syndromes (FSS) are common in adolescents, characterised by severe disability and reduced quality of life. Behavioural treatments such as acceptance and commitment therapy (ACT) has shown promising results in children and adolescents with FSS, but has focused on specific syndromes such as functional pain. The current study will compare the efficacy of group-based ACT with that of enhanced usual care (EUC) in adolescents with a range of FSS operationalised by the unifying construct of multiorgan bodily distress syndrome (BDS)...

Ensuring welfare in captive wild animal populations is important not only for ethical and legal reasons, but also to maintain healthy individuals and populations. An increased level of social behaviors such as aggression can reduce welfare by causing physical damage and chronic stress to animals. Recently, cortisol in hair has been advanced as a non-invasive indicator to quantify long-lasting stress in many species. The sensitivity of social behavior and hair cortisol concentration was evaluated in several groups of dorcas gazelles (Gazella dorcas)...
