    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. Methods: The sample consisted of 318 children (53% girls, M age =7. 7.26, SD=0.35). Hair strands were taken near the scalp from a posterior vertex position, and HCCs were tested for the first 3-cm hair segment. Parents provided information about their children's age, gender, parental education, children's stress (recent critical life events, daily hassles), health-related quality of life, and psychosomatic complaints. Body composition, blood pressure, retinal vessel diameters, and cardiorespiratory fitness were measured with established methods. Results: In multiple regression analyses, higher HCCs were weakly associated with increased BMI in girls (β=0.22, p

  4. [해외논문]   Fifteen-month-old infants' cortisol levels decrease after a 30-min-warm-up procedure  

    Zmyj, N. ; Schneider, S. ; Seehagen, S.
    Psychoneuroendocrinology v.76 ,pp. 11 - 13 , 2017 , 0306-4530 ,

    초록

    Stress-induction procedures designed to increase cortisol levels in infants have been ineffective in many studies. One reason might be that infants did not have sufficient time to settle into the laboratory environment prior to the start of the stress induction, and thus already had high baseline levels of cortisol. In this study we investigate whether an extended warm-up period reduces infants' (N=22) cortisol levels. Fifteen-month-old infants' saliva cortisol was measured upon arrival at the laboratory. Then, they were allowed to play with their parent. After 30min, cortisol was measured again. There was a decrease in cortisol after 30min of free play. Our study suggests that infants' cortisol levels decrease when infants have the opportunity to acclimatize to the test environment. An extended warm-up phase prior to stress induction procedures might be necessary to reliably increase cortisol levels in infants.

  5. [해외논문]   Copeptin - A potential endocrine surrogate marker of CCK-4-induced panic symptoms?

    초록

    Intravenous cholecystokinin-tetrapeptide (CCK-4) administration reliably and dose-dependently provokes panic anxiety in man, accompanied by adrenocorticotropic hormone (ACTH) and cortisol release. Preclinical findings suggest that behavioral and endocrine effects of CCK-4 are mediated via corticotropin-releasing hormone (CRH) release. Anxiogenic stimulation of the central CCK-receptors in man was shown to increase as well vasopressin (AVP), which acts synergistically with CRH as pituitary-adrenocortical axis stimulator during stress. Copeptin (CoP), the C-terminal part of pre-pro-AVP, is released in an equimolar ratio to AVP. It is more stable in the circulation and easier to determine than AVP and it was found to closely mirror the production of AVP. So far, CoP secretion has not been characterized during panic provocation. In 30 healthy male human subjects, we repeatedly measured CoP in plasma during a panic challenge and studied its correlation to Acute Panic Inventory (API) ratings and plasma ACTH and cortisol. CoP levels correlated positively with the increase in API ratings (r=0.41, p=0.03), while ACTH or cortisol did not (r=0.08, p=0.68 and r=0.12, p=0.53, respectively). CoP levels correlated also positively with ACTH (r=0.48, p=0.009) and cortisol (r=0.48, p=0.01) concentrations throughout the CCK-4 challenge. As expected, we found a positive correlation between plasma ACTH and cortisol levels (r=0.57, p=0.001). A vasopressinergic activation during CCK-4 induced panic was demonstrated, which was correlated positively to panic symptoms and pituitary-adrenocortical release. Our findings suggest a role of CoP as a potential surrogate marker of CCK-4 panic symptoms. Further studies are needed to replicate our results and to further clarify the role of CoP as a stress-sensitive hormone in different panic paradigms as well as in panic patients.

  6. [해외논문]   Trauma exposure relates to heightened stress, altered amygdala morphology and deficient extinction learning: Implications for psychopathology

    초록

    Stress exposure causes a structural reorganization in neurons of the amygdala. In particular, animal models have repeatedly shown that both acute and chronic stress induce neuronal hypertrophy and volumetric increase in the lateral and basolateral nuclei of amygdala. These effects are visible on the behavioral level, where stress enhances anxiety behaviors and provokes greater fear learning. We assessed stress and anxiety levels in a group of 18 healthy human trauma-exposed individuals (TR group) compared to 18 non-exposed matched controls (HC group), and related these measurements to amygdala volume. Traumas included unexpected adverse experiences such as vehicle accidents or sudden loss of a loved one. As a measure of aversive learning, we implemented a cued fear conditioning paradigm. Additionally, to provide a biological marker of chronic stress, we measured the sensitivity of the hypothalamus-pituitary-adrenal (HPA) axis using a dexamethasone suppression test. Compared to the HC, the TR group showed significantly higher levels of chronic stress, current stress and trait anxiety, as well as increased volume of the left amygdala. Specifically, we observed a focal enlargement in its lateral portion, in line with previous animal data. Compared to HC, the TR group also showed enhanced late acquisition of conditioned fear and deficient extinction learning, as well as salivary cortisol hypo-suppression to dexamethasone. Left amygdala volumes positively correlated with suppressed morning salivary cortisol. Our results indicate differences in trauma-exposed individuals which resemble those previously reported in animals exposed to stress and in patients with post-traumatic stress disorder and depression. These data provide new insights into the mechanisms through which traumatic stress might prompt vulnerability for psychopathology.

  7. [해외논문]   Maternal care and affective behavior in female offspring: Implication of the neurosteroid/GABAergic system  

    Borrow, A.P. ; Cameron, N.M.
    Psychoneuroendocrinology v.76 ,pp. 29 - 37 , 2017 , 0306-4530 ,

    초록

    In female rats, the proestrus phase of the estrous cycle is associated with decreased levels of anxiety-like and depressive-like behavior relative to the metestrus phase. Progesterone likely modulate these behaviors, in part through the influence of its metabolite, allopregnanolone (THP) on hippocampal GABA A R subunit expression. As natural variations in maternal care have been found to influence both progesterone levels at proestrus and anxiety-like behavior in female offspring, we sought to investigate the importance of maternal care and the estrous cycle on affective behavior in female rats that had received Low or High levels of licking/grooming (LG) during early life. Subjects were tested for anxiety-like behavior in the elevated plus maze at proestrus or metestrus or for estrous cycle-dependent changes in depressive-like anhedonic behavior with a saccharin preference test. GABA A R subunit expression, and THP levels in the dorsal hippocampus and in plasma were also evaluated. Estrous cycle phase influenced saccharine preference and hippocampal THP level in both phenotypes. Low LG animals showed higher levels of hedonic behavior and anxiety-like behavior, irrespective of estrous cycle phase, as well as lower THP levels within the dorsal hippocampus when compared to High LG animals. Only High LG animals showed positive correlations between hippocampal THP levels and GABA A R subunit expression, suggesting a relative insensitivity to THP's modulation of these receptor subunits in Low LG offspring. These findings suggest that natural variations in maternal care influence anxiety-like and hedonic behavior through the modulation of the neurosteroid/GABAergic system.

  8. [해외논문]   Hypothalamic-pituitary-adrenal axis activity and cognition in major depression: The role of remission status  

    Salvat-Pujol, N. ; Labad, J. ; Urretavizcaya, M. ; de Arriba-Arnau, A. ; Segalas, C. ; Real, E. ; Ferrer, A. ; Crespo, J.M. ; Jimenez-Murcia, S. ; Soriano-Mas, C. ; Menchon, J.M. ; Soria, V.

    초록

    Objectives: Neuropsychological deficits and hypothalamic-pituitary-adrenal (HPA) axis dysfunction have been described in major depressive disorder (MDD). We conducted an exploratory study to investigate the role of remission status in the relationship between HPA axis and cognition in MDD. Methods: Ninety-seven MDD patients (44 remitted, 53 non-remitted) and 97 healthy controls (HC) were evaluated. We measured verbal and visual memory, working memory, processing speed, attention, and executive function. Three HPA axis measures were assessed: cortisol awakening response (CAR), diurnal cortisol slope, and cortisol suppression ratio with 0.25mg of dexamethasone (DSTR). Multiple linear regression analyses were performed to study the relationship between cortisol measures and cognition while controlling for potential confounders. We conducted an overall analysis in all participants to compare both MDD-remitted and MDD non-remitted groups with respect to HC. Another analysis including MDD patients only was used to explore a moderating effect by remission status. Results: MDD patients showed poorer cognitive performance compared with HC, without significant differences between remitters and non-remitters. Cortisol measures did not differ between remitters and non-remitters. Although most HPA axis measures were not associated with cognitive dysfunction, we found significant associations between cognitive performance in MDD-remitters and cortisol measures for visual memory, processing speed and executive function. A significant moderating effect for remission status was found between cortisol diurnal slope (but neither CAR nor DSTR) and performance in processing speed or executive function. Conclusions: Remission status in MDD appears to moderate the association between some cognitive domains (processing speed and executive function) and HPA axis activity.

    초록

    The brain neuropeptide S (NPS) system has recently generated substantial interest and may be of major relevance for central stress regulation. The NPS receptor (NPSR1) is highly expressed in the limbic system, exogenous NPS exerts pronounced anxiolytic and fear-attenuating effects in rodents and extensive close crosstalk between the NPS system and the hypothalamic-pituitary-adrenal (HPA) axis has been demonstrated. In humans, associations between NPSR1 variants and anxiety and panic disorder, as well as amygdala responsiveness to fear- relevant faces and prefrontal cortex activity in a fear conditioning paradigm have been reported. Moreover, a NPSR1 sequence variant was found to be associated with cortisol stress responses in males.

  10. [해외논문]   Increased anxiety-like behaviors, but blunted cortisol stress response after neonatal hippocampal lesions in monkeys  

    Raper, J. ; Wilson, M. ; Sanchez, M. ; Payne, C. ; Bachevalier, J.
    Psychoneuroendocrinology v.76 ,pp. 57 - 66 , 2017 , 0306-4530 ,

    초록

    The hippocampus is most notably known for its role in cognition and spatial memory; however it also plays an essential role in emotional behaviors and neuroendocrine responses. The current study investigated the long-term effects of neonatal hippocampal lesions (Neo-Hibo) on emotional and hypothalamic-pituitary-adrenal (HPA) axis functioning. During infancy, unlike controls, Neo-Hibo monkeys exhibited enhanced expression of emotional behaviors (e.g. freezing, anxiety-like, and self-directed behaviors) when exposed to a human intruder (HI task). Upon reaching adulthood, they exhibited reduced freezing and hostility, but increased anxiety-like and self-directed behaviors during the HI task. Neo-Hibo monkeys behaved as if they systematically over-rated the risk inherent in the HI task, which supports Gray and McNaughton's septo-hippocampal theory of anxiety. Also, in adulthood, the increased levels of anxiety-like behaviors in Neo-Hibo monkeys were associated with a blunted cortisol response to the HI task. Examination of basal HPA axis function revealed that Neo-Hibo monkeys exhibited the typical diurnal cortisol decline throughout the day, but had lower cortisol concentrations in the morning as compared to controls. Taken together these data suggest that an intact hippocampus during development plays a larger role beyond that of inhibitory/negative feedback regulation of the HPA axis stress-activation, and may be critical for HPA axis basal functioning as well as for the stress response. The behavioral and neuroendocrine changes demonstrated in the current study are reminiscent of those seen in human or nonhuman primates with adult-onset hippocampal damage, demonstrating little functional compensation following early hippocampal damage.
