J Am Dent Assoc 2024; 155:496-503.e1. [PMID: 38520420 DOI: 10.1016/j.adaj.2024.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 02/14/2024] [Accepted: 02/18/2024] [Indexed: 03/25/2024]
Abstract
BACKGROUND Dental anxiety is a common problem for oral surgeries. This study investigated the effectiveness of wearing glasses with green lenses in reducing dental anxiety, blood pressure, heart rate, and intraoperative pain in patients undergoing first-time third-molar surgery. METHODS The authors planned this study as a randomized and parallel-group clinical trial. Patients' dental anxiety was measured with the use of a visual analog scale and a State-Trait Anxiety Inventory for baseline measurement purposes. At the same time, blood pressure, oxygen saturation, and heart rate values were recorded. Patients were given glasses with clear or green lenses, depending on their group. After 10 minutes, all parameters were measured again for preoperative measurement. Patients wore glasses with either green or clear lenses throughout the operation. After the operation, patients were asked to estimate the degree of intraoperative pain using the visual analog scale. RESULTS The study included 128 patients. On the basis of the change between baseline and preoperative measurements, the authors found a statistically significant difference in anxiety and heart rate. Intraoperative pain showed a significant difference between groups. No significant changes were found in blood pressure and oxygen saturation. CONCLUSIONS Patients with anxiety could wear low-cost, easy-to-use glasses with green lenses for 10 minutes before an operation to reduce anxiety and heart rate. In addition, wearing glasses during the surgical procedure can reduce intraoperative pain. PRACTICAL IMPLICATIONS By means of using glasses with green lenses throughout the procedure, existing anxiety and pain can be reduced. An operation can be performed more comfortably for both the patient and the dentist. This clinical trial was registered at ClinicalTrials.gov. The registration number is NCT05584696.

Neural and cortisol responses to acute psychosocial stress in work-related burnout: The Regensburg Burnout Project. Psychoneuroendocrinology 2024; 161:106926. [PMID: 38118266 DOI: 10.1016/j.psyneuen.2023.106926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 11/22/2023] [Accepted: 12/10/2023] [Indexed: 12/22/2023]
Abstract
BACKGROUND While several attempts have been made to elucidate the pathophysiology of burnout, neural stress responses have not yet been investigated. Therefore, the aim of this study was to examine salivary cortisol and - for the first time - neural responses to acute psychosocial stress within a strictly specified sample consisting of individuals suffering from burnout (BO group) and a healthy comparison group (HC group). METHODS After a multi-stage recruitment procedure based on burnout symptomatology and pathogenesis, 55 individuals suffering from burnout (25 women) and 61 individuals serving as HC group (31 women) out of an initial sample of 1022 volunteers were exposed to acute psychosocial stress during functional magnetic resonance imaging (fMRI) applying ScanSTRESS. RESULTS No differences were found between the BO and the HC group with respect to cortisol and mean neural stress responses. However, an exploratory comparison of neural stress responses of the first and second run of ScanSTRESS (exposure-time effect) revealed group-specific response patterns in one cluster peaking in the left dorsal anterior cingulate cortex (dACC). While the neural activation of the HC group was higher in the first compared to the second run of ScanSTRESS (i.e., decreasing activation), this pattern was reversed in the BO group (i.e., increasing activation). CONCLUSIONS Our analysis mainly did not provide evidence for altered acute cortisol and mean neural stress responses in burnout. However, the BO group was characterized by a limited capacity to show decreasing activation over stress exposure-time and exhibited instead increasing activation. Importantly, this group difference manifested in the left dACC which is both involved in neural stress processing and affected in individuals suffering from burnout. Given the present results, it seems promising to further examining temporal dynamics of neural stress responses in (sub-) clinical conditions such as burnout.

Abstract
Introduction Stress and anxiety are emotional states that often accompany patients who have to receive dental treatments, leading them to postpone or avoid treatments with the consequent deterioration of their oral health and, hence, their general condition. Music therapy has been shown to be an alternative to other treatments that are invasive and not without danger, such as anxiolytics or sedation. This systematic review and meta-analysis evaluated the effect of music therapy on anxiety and stress prior to dental treatments. Methods Studies published in PubMed (through Medline), Web of Science (WOS), Embase, and Cochrane Library databases were consulted up to October 2023. The inclusion criteria were established for intervention studies (randomized controlled trials, RCTs) according to the PICOS (population, intervention, comparison, outcomes, and study) strategy in subjects with dental stress and anxiety (participants) treated with music therapy (intervention) in comparison with patients without music therapy (control) and evaluating the response to treatment (outcomes). Results A total of 154 results were obtained, with 14 studies finally selected. The risk of bias and the methodological quality were assessed using the Cochrane Risk of Bias Tool and the Jadad scale, respectively. A random-effects meta-analysis was used to quantify the results of the pooled studies, while a fixed-effects meta-analysis was used for studies in the pediatric population. The meta-analysis of pooled studies found statistical significance in the subgroups of anxiety and anxiety-stress (p = 0.03 and p = 0.05, respectively), with an overall effect in favor of the intervention group (p = 0.005). Meta-analysis of the studies in the pediatric population showed considerable statistical significance for the experimental group (p < 0.00001). Conclusion Music therapy as a treatment for stress and anxiety, prior to dental treatment, proved to be effective in both children and adults although more well-designed randomized clinical studies are needed to validate its efficacy. Systematic review registration INPLASY, identifier 202312000.

The influence of pharmacological mineralocorticoid and glucocorticoid receptor blockade on the cortisol response to psychological stress. Prog Neuropsychopharmacol Biol Psychiatry 2024; 129:110905. [PMID: 38043634 DOI: 10.1016/j.pnpbp.2023.110905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 11/20/2023] [Accepted: 11/27/2023] [Indexed: 12/05/2023]
Abstract
The glucocorticoid cortisol is the end product of the hypothalamic-pituitary-adrenal (HPA) axis and crucial for the stress response in humans. Cortisol regulates numerous biological functions by binding to two different types of receptors: the mineralocorticoid receptor (MR) and the glucocorticoid receptor (GR). Both receptors are found in the brain where they are crucially involved in various mental functions and in feedback inhibition of cortisol release. The precise role of both receptors in the human stress response is not completely understood. In this study, we examined the effects of pharmacological blockade of the MR or the GR on stress-induced cortisol release in a sample of 318 healthy young men (M = 25.42, SD = 5.01). Participants received the MR antagonist spironolactone (300 mg), the GR antagonist mifepristone (600 mg), or a placebo and were subjected 90 min later to a social-evaluative stressor (Trier Social Stress Test) or a non-stressful control condition. We found significantly higher stress-induced cortisol release in the spironolactone group, whereas participants after mifepristone administration did not differ from the control groups. These results suggest that MR blockade results in attenuated fast negative feedback processes and emphasize the important role of the MR during the early phase of the stress response.

Abstract
This study aimed to investigate the relationship between job dissatisfaction (JD) and depressive symptoms and suicidal ideation among female workers. Additionally, it examined how the cumulative exposure to JD over multiple years can exacerbate the effect. We conducted our analyses on a nationwide sample of 6111 female workers from the Korean Longitudinal Survey of Women and Family (Waves 5-7). Depressive symptoms were measured using the 10-item version of the Centre for Epidemiologic Studies Depression Scale. JD was classified into quartiles (Q1-Q4), and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using generalised estimating equations. The overall prevalence of depressive symptoms and suicidal ideation among study participants was 13.9% and 2.4%, respectively. Our findings revealed that female workers with the highest level of JD (Q4) had a significantly greater risk of depressive symptoms (OR [95% CI]: 1.61 [1.37-1.89]) and suicidal ideation (OR [95% CI]: 2.08 [1.37-3.17]) after 2-year follow-up compared to those with the lowest level of JD (Q1). Consecutive exposure to JD over multiple years was also associated with depressive symptoms and suicidal ideation after a 2-year follow-up. For instance, women exposed to JD for three consecutive waves exhibited a high risk of depressive symptoms (OR [95% CI]: 1.61 [1.33-1.95]) and suicidal ideation (OR [95% CI]: 1.67 [1.04-2.70]). JD was positively associated with depressive symptoms and suicidal ideation. Our study suggests that JD is a risk factor for mental health problems in female workers.

J Affect Disord 2023; 339:127-135. [PMID: 37437718 DOI: 10.1016/j.jad.2023.07.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 06/23/2023] [Accepted: 07/08/2023] [Indexed: 07/14/2023]
Abstract
BACKGROUND The present study investigated an interpersonal model of development of depressive symptoms in employees, where occupational stress affects burnout, which in turn affects risk for depression, and whether this mediation is moderated by grit. METHODS A total of 11,421 participants, aged 19 to 65 years, who were employees of 18 private companies and local government organizations in Korea were included. They completed questionnaires, including the Korean version of occupational stress scale, Oldenburg Burnout Inventory, Center for Epidemiologic Studies Depression scale and Grit scale. Mediation and moderation analyses were carried out in the Statistical Package for the Social Sciences PROCESS macro. RESULTS The association between occupational stress and depressive symptoms was mediated by exhaustion (b = -0.256, 95 % CI [0.244, 0.268]) and disengagement (b = -0.052, 95 % CI [0.039, 0.065]). Moreover, the effect of exhaustion on depressive symptoms was moderated by each grit, with the effect being stronger for employees with low grit (b = 0.939, p < 0.001 for passion and b = 0.629, p < 0.001 for perseverance) than for those with high grit (b = 0.944, p < 0.001 for passion and b = 0.686, p < 0.001 for perseverance). LIMITATIONS The cross-sectional design of the study does not allow causal inferences. CONCLUSIONS These findings contribute to the understanding of how occupational stress predicts depressive symptoms in the workplace and provide practical implications for preventing burnout and nurturing grit to protect employees' mental health in the workplace.

Abstract
Stress can have a significant impact on the daily lives of individuals and can increase vulnerability to a number of medical conditions. This study aims to estimate the ratio of male to female participants in acute social stress research in healthy individuals. We examined original research articles published over the last 20 years. Each article was screened to determine the total number of female and male participants. We extracted data from 124 articles involving a total of 9539 participants. A total of 4221 (44.2%) participants were female, 5056 (53.0%) were male and 262 (2.7%) were unreported. Articles incorporating only females were significantly underrepresented compared to articles incorporating only males. Forty articles (63.5%) which presented data from both females and males, failed to analyse and interpret the results by sex, a significant methodological limitation. In conclusion, in the literature published over the last 20 years, female participants are significantly underrepresented. In the studies where females are represented, severe methodological limitations are apparent. Researchers should be conscious of sexual dimorphism, menstrual phase and use of hormonal contraception, which may impact the interpretation of their results.

Abstract
OBJECTIVE The renin-angiotensin-aldosterone system (RAAS) plays a relevant role in regulating blood pressure and thus maintaining cardiovascular homeostasis. Although it was recently shown that RAAS parameters are responsive to acute psychosocial stress, the psychobiological determinants of the acute stress-induced RAAS activation have not yet been investigated. In a randomized placebo-controlled design, we investigated potential psychological and physiological determinants of the RAAS response and underlying mechanisms. METHODS Fifty-seven young healthy male participants underwent either an acute standardized psychosocial stress test or a nonstress placebo task. We measured aldosterone in plasma and saliva, as well as renin, and the stress-reactive endocrine measures adrenocorticotropic hormone (ACTH), epinephrine, and norepinephrine in plasma at rest, immediately after the task and several times up to 3 hours thereafter. Moreover, we assessed stress-reactive psychological (anticipatory cognitive stress appraisal, mood, physical discomfort) and basal demographic-physiological measures (age, body mass index, blood pressure). RESULTS Acute psychosocial stress elicited changes in all assessed endocrine (p values ≤ .028, ηp2 values ≥ 0.07) and stress-reactive psychological measures (p values ≤ .003, ηp2 values ≥ 0.15). The basal parameter body mass index, the stress-reactive endocrine parameters ACTH and norepinephrine, and the psychological parameter anticipatory stress appraisal were identified as determinants of higher RAAS parameter reactivity to acute psychosocial stress. The association between anticipatory cognitive stress appraisal and plasma RAAS measures was fully mediated by ACTH increases (p values ≤ .044, ηp2 values ≥ 0.05). CONCLUSIONS Cognitive stress appraisal processes seem to modulate RAAS stress reactivity. This points to potential clinical implications for psychoeducative therapeutical interventions targeting stress appraisal processes to reduce endocrine stress reactivity.

Abstract
BACKGROUND Healthcare providers working in neonatal intensive care units (NICUs) are considered at high risk for psychological work-related stress. PURPOSE To evaluate both perceived and biological measures of work-related stress in neonatal healthcare professionals and to compare professionals working in the NICU with their colleagues working in less critical environments (ie, neonatal wards [NWs]). METHODS The salivary cortisol level at the beginning (CORT-B) and at the end (CORT-E) of a daily work shift was collected once a week for 6 weeks and a psychological questionnaire was submitted to NW and NICU workers of a tertiary university center. RESULTS No differences emerged in the overall cortisol secretion between professionals (NW 45 vs NICU 28), but the decrease in the mean cortisol values between CORT-B and CORT-E was less pronounced in NICU professionals (P < .001) who had greater psychological stress (P < .001). Lack of correlation between perceived and biological indexes was observed. IMPLICATIONS FOR PRACTICE NICU professionals reported greater levels of self-perceived psychological stress, especially in terms of professional self-doubt and the complexity of interactions with infants and their parents.The disconnection between psychological and biological indexes raises the issue that work-related stress might be covert to the professionals themselves. Dedicated resources should be developed to address quality of life and the work environment of NICU professionals. IMPLICATIONS FOR RESEARCH The absence of a correlation between perceived and biological indexes highlights the need to incorporate multidimensional physiological and biological measurements in evaluating burnout levels in neonatal healthcare providers.

Abstract
Work organization, such as shifts and night work, can interfere with the perception of work-related stress and therefore on the development of pathological conditions. Night shift work, particularly, can have a negative impact on workers’ wellbeing by interfering with the biological sphere. The aim of this study is to evaluate the associations between work activities, shift work effects and stress-related responses in 106 dock workers enrolled in southeast Italy. Dock workers’ tasks consist of complex activities that seemed to affect more sleep quality than work-related stress. An analysis of salivary biomarkers such as cortisol, α-amylase, melatonin and lysozyme was performed along with validated psycho-diagnostic questionnaires. Alpha-amylase showed a significant negative correlation with the effort/reward imbalance score; thus, the measurement of salivary α-amylase is proposed as a sensitive and non-invasive biomarker of work-related stress. This study may provide new insights into developing strategies for the management of night shift work. Salivary biomarkers should be further investigated in the future in order to develop simple and effective tools for the early diagnosis of work-related stress or its outcomes.

Abstract
BACKGROUND The gonadal hormone testosterone not only regulates sexual behavior but is also involved in social behavior and cognition in both sexes. Changes in testosterone secretion in response to stress have been reported. In addition, stress associated mental disorders such as borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) are characterized by alterations in basal testosterone metabolism. However, testosterone changes to stress have not been investigated in mental disorders such as BPD and PTSD so far. METHODS In the study described, we investigated testosterone reactivity to an acute psychosocial stressor, the Trier Social Stress Test (TSST). Our sample consisted of young adult women with BPD (n = 28), PTSD (n = 22) or both disorders (n = 22), and healthy control (n = 51). Based on previous studies on basal testosterone secretion in these disorders, we expected the stress-associated testosterone reactivity to be higher in the BPD group and lower in the PTSD group, when compared to the healthy control group. RESULTS The study could demonstrate an increase in testosterone after acute stress exposure across all groups and independent of BPD or PTSD status. Different possible explanations for the absence of a group effect are discussed. CONCLUSIONS From the results of this study, we conclude that stress-related changes in testosterone release are not affected by BPD or PTSD status in a female patient population. This study expands the knowledge about changes in gonadal hormones and stress reactivity in these disorders.

Effort-reward imbalance at work is associated with hair cortisol concentrations: Prospective evidence from the Dresden Burnout Study. Psychoneuroendocrinology 2019; 109:104399.

Abstract
Chronic stress experienced at work is considered a major health challenge for modern societies. In fact there is ample evidence that deleterious work environments, based on high efforts in relation to few rewards, substantially augment the risk for a number of highly prevalent diseases (e.g. ischemic heart disease, stroke). One potential pathway mediating these associations involves the stress-related activation of the hypothalamus-pituitary-adrenocortical (HPA) axis with proceeding alterations in the secretion of its main effector hormone cortisol. In this study we assessed a prospective, two-year effect of effort-reward imbalance (ERI) on cortisol secretion, based on a sub sample (N = 150; mean ± SD age: 42.4 ± 11.1; 84.0% female) of the ongoing Dresden Burnout Study (DBS). The provided ERI measures were collected as part of the online baseline and first follow up assessment. Further, cortisol secretion patterns over prolonged periods of time were evaluated in three consecutive years of laboratory baseline and follow up visits. Our findings suggest prospective associations between ERI and cortisol, indicating a blunted cortisol secretion in response to long-term work stress (p < 0.001). Given the regulatory properties of cortisol on various central and peripheral target tissues (e.g. cardiovascular system, liver, adipose tissue), a long-term decrease of cortisol availability can be hypothesized to cause multiple health-challenging consequences. Based on our findings, providing work environments where high efforts are always linked with high rewards have to be considered an important issue for employees health.

Attenuated cortisol reactivity to psychosocial stress is associated with greater visual dependency in postural control. Psychoneuroendocrinology 2019; 104:185-190. [PMID: 30856424 DOI: 10.1016/j.psyneuen.2019.02.028] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2018] [Revised: 01/21/2019] [Accepted: 02/28/2019] [Indexed: 12/29/2022]
Abstract
Despite known anatomical links between the hypothalamic-pituitary-adrenal (HPA) axis and the vestibular system, there are no studies on the relationship between postural control and HPA axis function. Visual dependence in postural control, often measured by increased postural sway on exposure to visual motion, is an indication of altered visual-vestibular integration with greater weighting towards visual cues for balance. Visual dependence is more common in older age and a range of vestibular and non-vestibular health conditions. The relationship between visual dependence in postural control was investigated in relation to cortisol reactivity to psychosocial stress (using the Trier Social Stress Test for groups: TSST-G), as an index of HPA axis function, in healthy young females. In those who exhibited a cortisol response (>2 nmol/l), a negative relationship between stress-induced cortisol reactivity and visual dependence in postural control was observed, since those with the largest cortisol response showed less visual motion induced postural sway (measured by force platform). This finding in healthy females indicates that subtle non-clinical differences in vestibular function are associated with dysregulated HPA axis activity as indicated by lower cortisol reactivity to psychosocial stress. It adds to the growing body of evidence linking blunted cortisol reactivity to stress to poor homeostatic regulation and potential negative health and behavioural outcomes.

Abstract
Repressors are well-known to monitor potential psychosocial threats to their self-esteem and self-concept. In research, repressors are traditionally categorised as those scoring low on trait anxiety and high on defensiveness (as measured by social desirability scales). Examining repressors' cortisol reactivity to a group socio-evaluative laboratory stressor could be an important way to extend work on the classic 'repressor dissociation', which proposes that this group experience higher levels of physiological stress, but lower levels of subjective affect, during stressful situations. Research however has focused mainly on repressors' higher, more risk-prone levels of autonomic, rather than hypothalamic-pituitary-adrenal (HPA), reactivity to stressful stimuli. We assessed cortisol reactivity using a group-based acute psychosocial stressor, the Trier Social Stress Test for groups (TSST-G), which required participants to individually perform public speaking and mental arithmetic tasks in front of up to six other group members, as well as an evaluative panel of judges. Seventy-seven healthy young females (mean age ± SD: 20.2 ± 3.2 years) took part, of which 64 met the conventional criterion for a response to the TSST-G (<15.5% increase from baseline sample). The Stress-Arousal Checklist was completed pre- and post-TSST-G. Participants also completed the Perceived Stress Scale, the Trait Anxiety Inventory and the Marlow-Crowne Social Desirability Scale. The latter two measures were used to provide a categorisation of repressive coping style. Participants identified as repressive copers exhibited significantly lower cortisol reactivity during the TSST-G. Repressors also self-reported less subjective stress. These findings provide some evidence against the notion of the repressor dissociation and are discussed in terms of how cortisol hyporeactivity may be a pathway through which repressive coping adversely affects health.

Abstract
Optimizing performance of individuals in acutely stressful work-related situations requires a deeper understanding of the interaction between the demands of the stimuli and an individual's associated physiological response. Identifying these responses is particularly germane for healthcare professionals, who experience episodes of acute stress on a regular basis. The purpose of this review was to examine and synthesize empirical literature to identify studies assessing physiological responses to acute stress, determine common methods for measuring acute stress in near real-time, and identify common research designs employed across industries. A modified PRISMA approach was followed. Systematic searches were conducted of four databases (PsycINFO, Medline, PubMed, and Turning Research into Practice [TRIP]) to access eligibility. Reference list searches and a hand search were also conducted to identify other articles suitable for inclusion. Studies selected examined an acute physiological response while participants were engaged in a stress-inducing task. Twenty-two articles were included. Fifteen (68.2%) were centered on the human service industry while only three (13.6%) focused on healthcare professionals. Half of the studies incorporated a simulation into the research design while only two (9.1%) articles looked at physiological responses in real-world settings. Heart rate and cortisol emerged as the most common physiological measures collected. This review demonstrates that acute stress is primarily assessed retrospectively, and that there is a pragmatic gap in methodological approach, with many data collection methods inappropriate for the healthcare environment. Future research should capitalize on advancements in sensor technology to passively examine acute stress in healthcare professionals.

Abstract
OBJECTIVE Deficits in empathy, an important part of social cognition, have been described in patients with borderline personality disorder (BPD). Importantly, psychosocial stress enhances emotional empathy in healthy participants. However, it remains unknown whether stress affects empathy in BPD. METHOD We randomized 47 women with BPD and 47 healthy women to either the Trier Social Stress Test or a control condition. Subsequently, all participants underwent the Multifaceted Empathy Test (MET), a measure of cognitive and emotional facets of empathy. RESULTS Across groups, stress resulted in a significant increase in cortisol and stress ratings. There was a significant stress × group interaction for emotional empathy (Fdf1,92 = 5.12, P = 0.04, ηp2 = 0.05). While there was no difference between patients with BPD and healthy participants after the control condition, patients with BPD had significantly lower emotional empathy scores after stress compared to healthy individuals. There were no effects for cognitive empathy. CONCLUSION The current finding provides first evidence that stress differentially affects emotional empathy in patients with BPD and healthy individuals such that patients with BPD showed reduced emotional empathy compared to healthy women after stress. Given the strong impact of stress on acute psychopathology in patients with BPD, such a response may exacerbate interpersonal conflicts in stress contexts and may be an important target for therapeutic interventions.

Abstract
OBJECTIVE The association between effort-reward imbalance (ERI) and various health outcomes has been well documented over the past 20 years, but the mechanisms responsible for this association remain unclear. The present meta-analysis assessed the associations of ERI and overcommitment (OC) in the workplace with hypothalamic-pituitary-adrenal (HPA) axis measures. METHODS Electronic databases were searched with the phrase "effort*reward*imbalance," which yielded 319 studies leading to 56 full-text studies being screened. Thirty-two studies within 14 articles met inclusion criteria and were meta-analyzed using mixed and random effects models. RESULTS Greater ERI was associated with increased HPA axis activity (r = .09, p < .001, k = 14, N = 2541). The cortisol awakening response (r = .14, p < .001, k = 9, N = 584) and cortisol waking concentrations (r = .12, p = .01, k = 6, N = 493) were the only HPA measures associated with ERI. OC was also associated with greater HPA axis activity (r = .06, p < .01, k = 10, N = 1918). Cortisol (PM) (r = .13, p = .02, k = 3, N = 295) was the only HPA measure associated with OC. CONCLUSIONS ERI and OC were similarly related with HPA responsivity. However, because OC moderated the relationship between ERI and HPA axis markers, the importance of OC should not be overlooked. Because OC is likely more malleable than ERI to intervention, this may be a promising avenue for future research.

Abstract
While epidemiological studies provide statistical evidence on associations of exposures such as stressful work with elevated risks of stress-related disorders (e.g., coronary heart disease or depression), additional information on biological pathways and biomarkers underlying these associations is required. In this contribution, we summarize the current state of the art on research findings linking stressful work, in terms of an established theoretical model-effort-reward imbalance-with a broad range of biomarkers. Based on structured electronic literature search and recent available systematic reviews, our synthesis of findings indicates that associations of work stress with heart rate variability, altered blood lipids, and risk of metabolic syndrome are rather consistent and robust. Significant relationships with blood pressure, heart rate, altered immune function and inflammation, cortisol release, and haemostatic biomarkers were also observed, but due to conflicting findings additional data will be needed to reach a firm conclusion. This narrative review of empirical evidence supports the argument that the biomarkers under study can act as mediators of epidemiologically established associations of work stress, as measured by effort-reward imbalance, with incident stress-related disorders.

Abstract
The European steel industry’s workforce is highly heterogeneous and consists of various occupational groups, presumably facing different psychosocial stressors. The few existing studies on the subject mainly focused on physical constraints of blue-collar workers, whereas the supposable psychosocial workload received only little research attention. This is remarkable considering the challenges associated with statutory required risk assessment of psychosocial hazards. Valid measures of hazard analysis must account for various stressors and reliably identify them, also between occupational groups. The present study, based on a sample of blue- and white-collar workers (N = 124) from the European steel industry, aims to provide a first insight into psychosocial stressors and strain at work in this rarely researched industrial sector. Furthermore, two well-known theoretical roadmaps in job analysis are examined regarding their utility for risk assessment in heterogeneous workforces: the German standard version of the Copenhagen Psychosocial Questionnaire (COPSOQ) and the short version of the effort–reward imbalance questionnaire. Hierarchical multiple regression analyses revealed that the COPSOQ was better suited to predict various strain indices in the present sample. Especially stressors relating to socioemotional aspects, such as work-privacy conflict, revealed a reasonable impact, indicating the need for comprehensive solutions at the organizational level instead of solutions focusing on single workplaces. To conclude, a broadly diversified and validated approach in psychosocial risk assessment is needed to adequately assess the variety of psychosocial factors at work and in different occupational groups.

Meta-analytical assessment of the effects of protocol variations on cortisol responses to the Trier Social Stress Test. Psychoneuroendocrinology 2017; 80:26-35.

Abstract
BACKGROUND The Trier Social Stress Test (TSST) is one of the most widely used laboratory stress tests. Exposure to this psychosocial stressor has been shown to stimulate an acute cortisol stress response in the majority of healthy individuals, while deviations from the typical pattern, i.e., cortisol reactivity dysfunctions have been linked to an ever-increasing number of negative health outcomes. However, significant variability between labs exists in strength of observed cortisol responses in healthy individuals. This variability raises the question of how to distinguish across labs between cortisol stress response patterns that reflect health risk from those that are due to methodological differences. Thus, we propose a systematic review and meta-analysis that aims at quantifying the effects of methodological variation in study and TSST protocol elements on cortisol stress responses in healthy individuals. METHODS Literature searches were conducted using standard databases for English language with key words including Trier Social Stress Test, TSST, Cortisol, and Laboratory Stressor among others. 186 studies met our inclusion criteria of healthy human participants without systemic immunological or endocrine dysfunction and provided sufficient information to compute a total of 237 sub-sample effect sizes. RESULTS AND DISCUSSION With regard to study protocol variations that may risk confounding baseline cortisol values and thus influence subsequent reactivity measures, meta-analytical examination revealed that acclimation periods pre-TSST below 30 or perhaps even 15min may suffice, at least as long as no interfering activities, i.e., questionnaires, are taking place during that timeframe. Assessing the effects of TSST protocol variations on cortisol response strength, several observations are noteworthy. First, shortening speech preparation time did not change cortisol responses in any way, nor did including questionnaires during that period show an effect. As such, our findings suggest that speech preparation time is one TSST element that can be used to reduce the burden for participants as well as laboratory logistics. Secondly, having an all female panel and instructing panel members to show negative instead of neutral behavior towards the participants both were associated with considerably reduced cortisol stress response strengths. Thirdly, several variables of interest, such as content of the speech task or gender match between active panel member and participant, were problematic to evaluate due to the large number of studies not reporting those details. This calls for future studies to report more details regarding potentially relevant protocol specifications.

Abstract
BACKGROUND Adverse childhood experiences (ACE) increase the risk to develop major depressive disorder (MDD) and obesity or metabolic syndrome in adulthood. In addition, ACE may be associated with an exaggerated endocrine response to stress, which, in turn, may lead to enhanced food intake resulting in obesity and metabolic problems. METHODS We systematically examined the stress response and consecutive food intake in 32 women with MDD and ACE as determined by a clinical interview (Early Trauma Inventory), 52 women with MDD without ACE, 22 women with ACE but no current or lifetime MDD and 37 healthy women without either MDD or ACE. All participants underwent a psychosocial stress test (Trier Social Stress Test, TSST) and a control condition (Placebo-TSST) before they were offered a buffet of snacks. Participants were not aware that the primary outcome variable was the amount of consumed kilocalories (kcal). RESULTS The four groups did not differ in demographic variables. Stress resulted in higher cortisol release and higher blood pressure compared to the control condition. Patients with MDD without ACE had a significantly lower cortisol response to stress compared to controls. Across groups, we found higher kcal intake after stress compared to the control condition. Comparing high and low cortisol responders to stress, higher kcal intake after stress was only seen in those with low cortisol release. CONCLUSIONS This study provides evidence that blunted rather than enhanced cortisol release to stress might lead to increased food intake, independent from MDD and ACE.

Abstract
BACKGROUND This study aimed to identify the association between occupational stress and depression-well-being by proposing a comprehensive and flexible job burden-capital model with its corresponding hypotheses. METHODS For this research, 1618 valid samples were gathered from the electronic manufacturing service industry in Hunan Province, China; self-rated questionnaires were administered to participants for data collection after obtaining their written consent. The proposed model was fitted and tested through structural equation model analysis. RESULTS Single-factor correlation analysis results indicated that coefficients between all items and dimensions had statistical significance. The final model demonstrated satisfactory global goodness of fit (CMIN/DF = 5.37, AGFI = 0.915, NNFI = 0.945, IFI = 0.952, RMSEA = 0.052). Both the measurement and structural models showed acceptable path loadings. Job burden and capital were directly associated with depression and well-being or indirectly related to them through personality. Multi-group structural equation model analyses indicated general applicability of the proposed model to basic features of such a population. Gender, marriage and education led to differences in the relation between occupational stress and health outcomes. CONCLUSIONS The job burden-capital model of occupational stress-depression and well-being was found to be more systematic and comprehensive than previous models.

Physiological adaptations to chronic stress in healthy humans - why might the sexes have evolved different energy utilisation strategies? J Physiol 2016; 594:4297-307.

Abstract
KEY POINTS The human stress response activates the autonomic nervous system and endocrine systems to increase performance during environmental challenges. This response is usually beneficial, improving the chance of overcoming environmental challenges, but costs resources such as energy. Humans and other animals are known to adapt their responses to acute stress when they are stimulated chronically, presumably to optimise resource utilisation. Characterisation of these adaptations has been limited. Using advanced imaging techniques, we show that cardiovascular and endocrine physiology, reflective of energy utilisation during acute stress, and energy storage (fat) differ between the sexes when they are exposed to chronic stress. We examine possible evolutionary explanations for these differences, related to energy use, and point out how these physiological differences could underpin known disparities between the sexes in their risk of important cardiometabolic disorders such as obesity and cardiovascular disease. ABSTRACT Obesity and associated diseases, such as cardiovascular disease, are the dominant human health problems in the modern era. Humans develop these conditions partly because they consume excess energy and exercise too little. Stress might be one of the factors contributing to these disease-promoting behaviours. We postulate that sex-specific primordial energy optimisation strategies exist, which developed to help cope with chronic stress but have become maladaptive in modern societies, worsening health. To demonstrate the existence of these energy optimisation strategies, we recruited 88 healthy adults with varying adiposity and chronic stress exposure. Cardiovascular physiology at rest and during acute stress (Montreal Imaging Stress Task), and body fat distribution were measured using advanced magnetic resonance imaging methods, together with endocrine function, cardiovascular energy use and cognitive performance. Potential confounders such as lifestyle, social class and employment were accounted for. We found that women exposed to chronic stress had lower adiposity, greater acute stress cardiovascular responses and better cognitive performance. Conversely, chronic stress-exposed men had greater adiposity and lower cardiovascular responses to acute stress. These results provide initial support for our hypothesis that differing sex-specific energy conservation strategies exist. We propose that these strategies have initially evolved to benefit humans but are now maladaptive and increase the risk of disorders such as obesity, especially in men exposed to chronic stress.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:432.

Abstract
Mainstream psychological stress theory claims that it is important to include information on people’s ways of coping with work stress when assessing the impact of stressful psychosocial work environments on health. Yet, some widely used respective theoretical models focus exclusively on extrinsic factors. The model of effort-reward imbalance (ERI) differs from them as it explicitly combines information on extrinsic and intrinsic factors in studying workers’ health. As a growing number of studies used the ERI model in recent past, we conducted a systematic review of available evidence, with a special focus on the distinct contribution of its intrinsic component, the coping pattern “over-commitment”, towards explaining health. Moreover, we explore whether the interaction of intrinsic and extrinsic components exceeds the size of effects on health attributable to single components. Results based on 51 reports document an independent explanatory role of “over-commitment” in explaining workers’ health in a majority of studies. However, support in favour of the interaction hypothesis is limited and requires further exploration. In conclusion, the findings of this review support the usefulness of a work stress model that combines extrinsic and intrinsic components in terms of scientific explanation and of designing more comprehensive worksite stress prevention programs.

Abstract
Evidence of the link between job strain and cortisol levels has been inconsistent. This could be due to failure to account for cortisol variability leading to underestimated standard errors. Our objective was to model the relationship between job strain and the whole cortisol curve, accounting for sources of cortisol variability. Our functional mixed-model approach incorporated all available data-18 samples over 3 days-and uncertainty in estimated relationships. We used employed participants from the Multi-Ethnic Study of Atherosclerosis Stress I Study and data collected between 2002 and 2006. We used propensity score matching on an extensive set of variables to control for sources of confounding. We found that job strain was associated with lower salivary cortisol levels and lower total area under the curve. We found no relationship between job strain and the cortisol awakening response. Our findings differed from those of several previous studies. It is plausible that our results were unique to middle- to older-aged racially, ethnically, and occupationally diverse adults and were therefore not inconsistent with previous research among younger, mostly white samples. However, it is also plausible that previous findings were influenced by residual confounding and failure to propagate uncertainty (i.e., account for the multiple sources of variability) in estimating cortisol features.

Abstract
Virtual reality (VR) exposure therapy is becoming increasingly established, but the mode of action is not well understood. One potential efficacy factor might be physiological arousal. To investigate arousal during VR exposure, we exposed 40 patients with acrophobia and 40 matched healthy controls to a VR height challenge and assessed subjective (fear ratings) and physiological (heart rate, skin conductance level, salivary cortisol) fear reactions. Patients experienced a significant increase of subjective fear, heart rate and skin conductance level. Unexpectedly, controls, who reported no subjective fear, also showed an increase in heart rate and skin conductance. There was no increase in salivary cortisol levels in either group. Physiological arousal in acrophobic patients, in contrast to subjective fear, might not be stronger than that of controls confronted with height cues in VR, indicating marked discordance across symptom domains. The lack of a cortisol response in a clearly stressful paradigm warrants further study.

Abstract
Physical fitness has salutary psychological and physical effects in older adults by promoting neuroplasticity and adaptation to stress. In aging, however, the effects of fitness on the hypothalamic-pituitary-adrenal (HPA) axis are mixed. We investigated the association between cardiorespiratory fitness and HPA activity in healthy elderly men (n = 22, mean age 68 y; smokers, obese subjects, those taking drugs or reporting recent stressful events were excluded), by measuring in saliva: i) daily pattern of cortisol secretion (6 samples: 30' post-awakening, and at 12.00, 15.00, 18.00, 21.00, 24.00 h); and ii) the cortisol response to a mental challenge. Cardiorespiratory fitness (VO2max) was estimated using the Rockport Walking Test and the participants were assigned to high-fit (HF, ≥60°, n = 10) and low-fit (LF, ≤35°, n = 12) groups according to age-specific percentiles of VO2max distribution in the general population. At all daytimes, basal cortisol levels were lower in the HF than the LF group, most notably in the evening and midnight samples, with a significant main effect of physical fitness for cortisol levels overall; the area-under-the-curve for total daily cortisol output was significantly smaller in the HF group. Among the subjects who responded to mental stress (baseline-to-peak increment >1.5 nmol/L; n = 13, 5 LF, 8 HF), the amplitude of cortisol response and the steepness of recovery decline displayed an increasing trend in the HF subjects, although between-group differences failed to reach the threshold for significance. In conclusion, cardiorespiratory fitness in healthy aging men is negatively correlated with daily cortisol output and contributes to buffering the HPA dysregulation that occurs with advancing age, thus possibly playing a beneficial role in contrasting age-related cognitive and physical decline.

Abstract
INTRODUCTION The aim of this study was to determine the effect of music therapy on patients suffering dental anxiety. In addition, a second objective was to determine the correlation between salivary cortisol and other physiologic parameters. METHODS 34 patients were randomly assigned to the control group and the experimental group. For each patient was measured for salivary cortisol, stimulate salivary flow, blood pressure, heart rate, oxygen saturation and body temperature. Student t-test and Chi2 were applied to analyze significant differences between the studied variables before and after the unpleasant stimulation causes anxiety for dental treatment. RESULTS Initially, both groups registered the same level of anxiety. In the second measurement, significant differences were registered in the salivary cortisol concentration, systolic and diastolic pressure, heart rate, body temperature and stimulated salivary flow for treated group with music therapy. CONCLUSION Music therapy has a positive effect in control of dental anxiety.

Abstract
Background The education system in Germany is beginning to witness a sea change, lately, owing to the country’s ratification of the United Nation’s Convention on the Rights of Persons with Disabilities. The enactment is aiming at making provision for special education teachers to share the same teaching platform and institution with other teachers for teaching children from all backgrounds, irrespective of their needs. While promoting the benefits of collaborative teaching, this provision would also effectively establish role demarcation among teachers. However, the level of participation and adaptiveness displayed by individual teachers would play a major role in determining the success or failure of the intended collaborative framework. Collaboration also becomes challenging due to the level of stress involved in the teaching profession. The fact that only 65 % of teachers in Germany reach retirement age while still in service, primarily due to psychiatric illness, has posed questions on adopting the collaborative framework for teachers from diverse backgrounds. In other words, it can be stated that the process of collaborating with teachers from different professional backgrounds and with varying levels of skills will potentially lead to further stress. The stress-related psychological states, developed through the collaborative processes, might affect the biological stress-response systems of the participating teachers. With stress-response contributing directly to the pathogenesis of stress-related diseases and disorders in the long term, it would be important to contain the ripple effect of collaborative framework that the enactment intends to establish between SEN (special educational needs) teachers and others. Methods In addition to impacting the long-term health of teachers, the collaborative framework is also suggestive of having similar effects on students studying special education (SEN students). A study was conducted to examine the stress levels associated with the collaborative framework. An expression in terms of two (group affiliation) × 2 (measurement time) between subjects design was implemented to examine the effects of an Acceptance and Commitment Training on the subjective tension of a sample (N = 68) of SEN students. The sample was split into an intervention and a control group (IG and CG). The effects of the training on collaborative competence were examined using the Chi-square test. Questionnaire and role plays were used to assess the collaborative competence and the subjective tension. Results The participants had significant stress levels and displayed an uncooperative attitude during the initial assessment. However, these results reversed after the Acceptance and Commitment Training. Significant decrease in stress levels and improved cooperation were evident among the participants in the intervention group, as opposed to the participants of the control group. Conclusions The findings of this study show that the Acceptance and Commitment Training is an appropriate medium to establish and develop collaboration skills, and an effective technique to reduce high levels of subjective stress. Furthermore, the training evaluation and feedback indicate that it is well-accepted by all participants. The training is also endorsed as a practically relevant medium to help SEN students collaborate and combat stress.

Abstract
Changes in cortisol and shame are commonly elicited by psychosocial stressors involving social-evaluative threat. According to social self preservation theory, this coordinated psychobiological response is adaptive. Individuals with a history of depression, however, may exhibit diminished cortisol reactivity to acute stressors, which could interfere with coordinated cortisol and shame responses. The present study examined temporal relations between cortisol and shame responses to a psychosocial stress task in young adults who varied in their history of depression (56 remitted-depressed, 46 never-depressed). Lagged effects multilevel models revealed that depression history moderated relations between cortisol levels and shame ratings 25-55min later. The pattern of these interactions was similar: whereas higher cortisol levels predicted increases in shame in never-depressed individuals, cortisol levels were unrelated to shame responses in remitted-depressed individuals. Findings suggest a dissociation between cortisol and shame responses to stress in individuals with a history of depression.

Abstract
The present study examined the incidence of chronic stress in business executives (109 subjects: 75 male and 34 female) and its relationship with cortisol levels, cognitive performance, and autonomic nervous system (ANS) reactivity after an acute mental stressor. Blood samples were collected from the subjects to measure cortisol concentration. After the sample collection, the subjects completed the Lipp Inventory of Stress Symptoms for Adults and the Stroop Color-Word Test to evaluate stress and cognitive performance levels, respectively. Saliva samples were collected prior to, immediately after, and five minutes after the test. The results revealed that 90.1% of the stressed subjects experienced stress phases that are considered chronic stress. At rest, the subjects with chronic stress showed higher cortisol levels, and no gender differences were observed. No differences were found between the stressed and non-stressed subjects regarding salivary amylase activity prior to test. Chronic stress also impaired performance on the Stroop test, which revealed higher rates of error and longer reaction times in the incongruent stimulus task independently of gender. For the congruent stimulus task of the Stroop test, the stressed males presented a higher rate of errors than the non-stressed males and a longer reaction time than the stressed females. After the acute mental stressor, the non-stressed male group showed an increase in salivary alpha-amylase activity, which returned to the initial values five minutes after the test; this ANS reactivity was not observed in the chronically stressed male subjects. The ANS responses of the non-stressed vs stressed female groups were not different prior to or after the Stroop test. This study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive performance.

Abstract
We examined the influence of work-related effort-reward imbalance and overcommitment to work (OC), as derived from Siegrist's Effort-Reward Imbalance (ERI) model, on the hypothalamic-pituitary-adrenocortical (HPA) axis. We hypothesized that, among healthy workers, both cortisol and dehydroepiandrosterone (DHEA) secretion would be increased by effort-reward imbalance and OC and, as a result, cortisol-to-DHEA ratio (C/D ratio) would not differ by effort-reward imbalance or OC. The subjects were 115 healthy female nursery school teachers. Salivary cortisol, DHEA, and C/D ratio were used as indexes of HPA activity. Mixed-model analyses of variance revealed that neither the interaction between the ERI model indicators (i.e., effort, reward, effort-to-reward ratio, and OC) and the series of measurement times (9:00, 12:00, and 15:00) nor the main effect of the ERI model indicators was significant for daytime salivary cortisol, DHEA, or C/D ratio. Multiple linear regression analyses indicated that none of the ERI model indicators was significantly associated with area under the curve of daytime salivary cortisol, DHEA, or C/D ratio. We found that effort, reward, effort-reward imbalance, and OC had little influence on daytime variation patterns, levels, or amounts of salivary HPA-axis-related hormones. Thus, our hypotheses were not supported.

Abstract
Previous studies have tested the relationship between chronic stress and sex hormones, but inconsistent results have been found. One possibility is that this association may depend on other biological factors. This study examined the relationship between stressful life events (LE) and sex hormones in men, and whether cortisol is involved in this relationship. From a total number of 2906 men who completed a screening for the early detection of prostate cancer, 139 healthy men (mean ± SD age, 57.8 ± 5.7 years) were included in this study. Participants were assessed with the Holmes and Rahe questionnaire in relation to their experience of LE during the previous 1-5 years. Salivary and serum cortisol was measured at 08:00-09:00 h, as well as luteinizing hormone (LH), total testosterone, epinephrine (E) and norepinephrine (NE). LE weight sum and LE number positively correlated with LH (r = 0.293, p = 0.004; r = 0.220, p = 0.031, respectively). In a multiple regression analysis, LE-sum explained an additional and significant 10.4% of the variance in LH levels, after statistically controlling for the effects of age, waist circumference (WC) and BMI (F(1,90) = 6.61, p < 0.05). Importantly, cortisol interacted with LE in relation to total testosterone. In men with high cortisol values (≥15.4 µg/dl), there was a statistically significant positive relationship between LE number and total testosterone levels (p = 0.05), while LE were unrelated to total testosterone in men with low cortisol. LE correlated with sex hormones, predicting LH values, and in men with high cortisol levels shows a possible moderator effect of cortisol on the relationship between LE and total testosterone.

Neurobiol Aging 2014; 36:257-64. [PMID: 25066239 PMCID: PMC4274312 DOI: 10.1016/j.neurobiolaging.2014.06.022] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2014] [Revised: 06/06/2014] [Accepted: 06/24/2014] [Indexed: 02/01/2023]
Abstract
Elevated glucocorticoid (GC) levels are hypothesized to be deleterious to some brain regions, including white matter (WM). Older age is accompanied by increased between-participant variation in GC levels, yet relationships between WM integrity and cortisol levels in older humans are underexplored. Moreover, it is unclear whether GC-WM associations might be general or pathway specific. We analyzed relationships between salivary cortisol (diurnal and reactive) and general measures of brain WM hyperintensity (WMH) volume, fractional anisotropy (gFA), and mean diffusivity (gMD) in 90 males, aged 73 years. Significant associations were predominantly found between cortisol measures and WMHs and gMD but not gFA. Higher cortisol at the start of a mild cognitive stressor was associated with higher WMH and gMD. Higher cortisol at the end was associated with greater WMHs. A constant or increasing cortisol level during cognitive testing was associated with lower gMD. Tract-specific bases of these associations implicated anterior thalamic radiation, uncinate, and arcuate and inferior longitudinal fasciculi. The cognitive sequelae of these relationships, above other covariates, are a priority for future study. We correlated salivary cortisol and brain white matter (WM) measures in older males. Cortisol was measured diurnally and in reaction to a cognitive challenge. Diffusion tensor magnetic resonance imaging (fractional anisotropy and mean diffusivity) and total hyperintensity volume measured WM integrity. WM-cortisol relations were found for mean diffusivity and hyperintensity volume but not fractional anisotropy. Higher cortisol in response to cognitive stressor denoted lower WM integrity.

Abstract
CONTEXT Meditation is proposed as an anti-stress practice lowering allostatic load and promoting well-being, with brief formats providing some of the benefits of longer interventions. OBJECTIVES PsychoNeuroEndocrinoImmunology-based meditation (PNEIMED) combines the teaching of philosophy and practice of Buddhist meditation with a grounding in human physiology from a systemic and integrative perspective. We evaluated the effects of four-day PNEIMED training (30 h) on subjective and objective indices of stress in healthy adults. DESIGN A non-randomized, controlled, before-and-after study was conducted. Participants (n = 125, mostly health practitioners) answered a questionnaire rating stress symptom before (T0) and after (Tf) a PNEIMED course. In an additional sample (n = 40; smokers, overweight persons, women taking contraceptives, and subjects with oral pathologies were excluded), divided into PNEIMED-attending (intervention, n = 21) and non-meditating (control, n = 19) groups, salivary cortisol was measured upon awakening and during a challenging mental task. RESULTS Self-rated distress scores were highly reduced after the PNEIMED course. In the intervention group, improvement of psychological well-being was accompanied by decrease in cortisol levels at awakening. No T0-vs-Tf changes in distress scores and morning cortisol were found in controls. Based on baseline-to-peak increment of cortisol response at T0, 26 subjects (n = 13 for each group) were classified as task-responders. The amplitude and duration of the cortisol response decreased after PNEIMED, whereas no effects were found in controls. CONCLUSIONS Brief PNEIMED training yields immediate benefits, reducing distress symptoms and adrenocortical activity under basal and stimulated conditions. PNEIMED may represent an effective practice to manage stress and anxiety, particularly among subjects facing a multitude of job-related stressors, such as healthcare workers.

Abstract
OBJECTIVE The evidence on whether there is work stress related dysregulation of the hypothalamic-pituitary-adrenal axis is equivocal. This study assessed the relation between work stress and diurnal cortisol rhythm in a large-scale occupational cohort, the Whitehall II study. METHODS Work stress was assessed in two ways, using the job-demand-control (JDC) and the effort-reward-imbalance (ERI) models. Salivary cortisol samples were collected six times over a normal day in 2002-2004. The cortisol awakening response (CAR) and diurnal cortisol decline (slope) were calculated. RESULTS In this large occupational cohort (N = 2,126, mean age 57.1), modest differences in cortisol patterns were found for ERI models only, showing lower reward (β = -0.001, P-value = 0.04) and higher ERI (β = 0.002, P-value = 0.05) were related to a flatter slope in cortisol across the day. Meanwhile, moderate gender interactions were observed regarding CAR and JDC model. CONCLUSIONS We conclude that the associations of work stress with cortisol are modest, with associations apparent for ERI model rather than JDC model.

Abstract
BACKGROUND Research endeavors aiming to evaluate the effect of prolonged psychological distress on the immune system have been pursed over the past decades. Due to the complexity of the two systems involved, the mental and immune status, a large number of questions still remains to be addressed. AIM In the present study, we aimed to test if chronic distress is associated with pro- and anti-inflammatory cytokine levels in a well-defined study cohort. METHODS We recruited 42 inpatients suffering from post-traumatic embitterment disorder (PTED), a condition that has been demonstrated to cause intense and persistent psychological distress. Study participants completed established questionnaires to evaluate stress perception, depression and quality of life before and after psychotherapy, aiming to improve stress coping. Venous blood samples to detect serum levels of pro- and anti-inflammatory cytokines [interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ] were obtained pre- and post-treatment. RESULTS The psychological assessments showed an increase of quality of life, a decrease of perceived stress and depressive symptoms, between the two groups. These findings are not associated with significant alterations of the cytokine levels before and after treatment. CONCLUSIONS In our study, the psychological treatment of inpatients suffering from chronic psychological distress does not result in changes in cytokine levels. Further research with a broader analysis of immune markers and enhanced detection methods may be required to unveil psycho-immunological association in PTED patients.

Abstract
Evidence for a detrimental impact of chronic work stress on health has accumulated in epidemiological research. Recent studies indicate altered hypothalamus-pituitary-adrenal (HPA) axis regulation as a possible biological pathway underlying the link between stress and disease. However, the direction of dysregulation remains unclear, with reported HPA hyper- or hyporeactivity. To disentangle potential effects on different functional levels in the HPA axis, we examined responses using two pharmacological stimulation tests in 53 healthy teachers (31 females, 22 males; mean age: 49.3 years; age range: 30-64 years): a low-dose adrenocorticotrophic hormone (ACTH(1-24), Synacthen) test was used to assess adrenal cortex sensitivity and the combined dexamethasone-corticotropin releasing hormone (DEX-CRH) test to examine pituitary and adrenal cortex reactivity. Blood and saliva samples were collected at - 1,+15,+30,+45,+60,+90,+120 min. Emotional exhaustion (EE), the core dimension of burnout, was measured with the Maslach Burnout Inventory. Overcommitment (OC) was assessed according to Siegrist's effort-reward-imbalance model. We found a significant association between EE and higher plasma cortisol profiles after Synacthen (p = 0.045). By contrast, OC was significantly associated with attenuated ACTH (p = 0.045), plasma cortisol (p = 0.005), and salivary cortisol (p = 0.023) concentrations following DEX-CRH. Results support the notion of altered HPA axis regulation in chronically work-stressed teachers, with differential patterns of hyper- and hyporeactivity depending on individual stress condition and the tested functional level of the HPA axis.

Abstract
BACKGROUND According to the effort-reward-imbalance (ERI) model, a lack of reciprocity between costs and gains at work increases the risk for adverse health outcomes. Inflammation has been shown to play a crucial role in a variety of stress-related diseases and alterations in immune system glucocorticoid sensitivity may help to explain the increased risk for cardiovascular disease (CVD) and depression related to chronic work stress. METHODS Changes in lipopolysaccharide (LPS)-induced interleukin (IL)-6 production and inhibition of IL-6 production by dexamethasone in reaction to the Trier Social Stress Test (TSST) were assessed in forty-six healthy school teachers to test whether chronic work stress is accompanied by alterations in inflammatory activity and glucocorticoid sensitivity of the innate immune system. RESULTS High ERI was associated with an increase in pro-inflammatory potential, reflected in elevated IL-6 production before and after stress and with a lower capacity of dexamethasone to suppress IL-6 production in vitro over all measurement time points. ERI was not associated with stress-related changes in GC sensitivity. CONCLUSION The present findings suggest a less effective anti-inflammatory regulation by glucocorticoids in teachers suffering from chronic work stress.

Abstract
This experiment tested the hypothesis that self-focused attention might increase cortisol release. Social self-preservation theory suggests that social evaluation and associated feelings of shame are associated with cortisol reactivity, whereas one implication of objective self-awareness theory is that self-critical awareness and associated feelings of anxiety might be associated with increases in cortisol. 120 participants completed a public speech task either in front of an evaluative panel (social threat), in a non-evaluative setting while watching themselves in real-time on a television (self-focus), or in the mere presence of a non-evaluative person (control). Cortisol increased comparably among men in the social threat and self-focus conditions, but not among men in the control condition. There were no effects for women. Shame was correlated with increased cortisol in the social threat condition, whereas anxiety was correlated with increased cortisol in the self-focus condition. One broad implication of this work is that negative evaluation may increase cortisol regardless of whether this source comes from oneself or others.

Abstract
OBJECTIVES To determine whether men and women with repeated ERI exposure have increased BP means or higher hypertension incidence over a 3-year follow-up. To examine the potential modifying effect of age and overcommitment. METHODS The study cohort was composed of 1,595 white-collar workers (629 men and 966 women) assessed at baseline and 3-year follow-up. Ambulatory BP measures were taken every 15 min during a working day. ERI at work was self-reported using validated scales. BP means at follow-up and cumulative incidence of hypertension were respectively modeled with analyses of covariance (ANCOVA) and log-binomial regression. RESULTS Among men, no association was observed between repeated ERI exposure and BP. Among women, age had a modifying effect. Women <45 years old exposed to ERI at both times had significantly higher BP means at follow-up (122.2/78.9 mmHg) than those unexposed (120.4/77.4 mmHg). In women ≥45 years old, the cumulative incidence of hypertension was 2.78 (95% CI: 1.26-6.10) times higher among those exposed to ERI at both times. Men and women in the higher tertile of overcommitment had higher BP means (men: 128.9/82.2 mmHg, women: 121.9/78.0 mmHg) than those in the lower tertile (men: 127.2/81.3 mmHg, women: 120.6/77.0 mmHg). CONCLUSION This prospective study showed that, among women, repeated ERI exposure led to a significant age-specific increase in BP means and a major age-specific increase in hypertension incidence. These results suggest that primary intervention aimed at reducing ERI may contribute to lower BP and prevent hypertension in women.

Abstract
Interindividual variability in the regulation of the human stress system accounts for a part of the individual's liability to stress-related diseases. These differences are influenced by environmental and genetic factors. Early childhood adversity is a well-studied environmental factor affecting an individual's stress response which has been shown to be modulated by gene-environment interaction (GxE). Neuropeptide Y (NPY) plays a role in stress regulation and genetic variation in NPY may influence stress responses. In this study, we analyzed the association of a common variant in the NPY gene promoter, rs16147, with cortisol and ACTH responses to acute psychosocial stress in young adults from the Mannheim Study of Children at Risk (MARS), an ongoing epidemiological cohort study following the outcome of early adversity from birth into adulthood. We found evidence of a GxE interaction between rs16147 and early adversity significantly affecting HPA axis responses to acute psychosocial stress. These findings suggest that the neurobiological mechanisms linking early adverse experience and later neuroendocrine stress regulation are modulated by a gene variant whose functional relevance is documented by increasing convergent evidence from in vitro, animal and human studies.

Abstract
BACKGROUND Previous studies have tested the relationship between stressful life events (LE) and cancer onset, but inconsistent results have been found. One possibility is that the LE-cancer relation may depend on other biological factors pertinent to stress and cancer. METHODS This study examined the relationship between LE and prostate specific antigen (PSA) levels, a tumor marker, and whether cortisol mediates or moderates a LE-PSA relationship. During a voluntary screening for prostate cancer risk, 139 men (mean age=57.3 years) were assessed with the Holmes and Rahe questionnaire about their LE during the past 1-5 years, and their PSA and serum cortisol levels were measured. RESULTS LE and cortisol alone were unrelated to PSA. However, statistically controlling for age, body mass index and the ratio of triglycerides to HDL cholesterol, we found evidence for a synergistic interaction between LE and cortisol. Among men with low cortisol, number of LE were inversely and significantly correlated with PSA (r=-0.265, p<0.05), while in men with high cortisol, number of LE were positively and significantly correlated with PSA (r=0.344, p<0.01). These results more consistently stemmed from the effects of uncontrollable LE. Similar results were found, using a clinically significant PSA cut-off. CONCLUSIONS These results suggest considering the joint effects of psychosocial and biological factors in relation to possible cancer risk, where the hypothalamic pituitary adrenal axis may moderate stress-cancer risk associations.

Abstract
RATIONALE Abuse and neglect are highly prevalent in children and have enduring neurobiological effects. Stressful early life environments perturb the hypothalamic-pituitary-adrenal (HPA) axis, which in turn may predispose to psychiatric disorders in adulthood. However, studies of childhood maltreatment and adult HPA function have not yet rigorously investigated the differential effects of maltreatment subtypes, including physical abuse. OBJECTIVE In this study, we sought to replicate our previous finding that childhood maltreatment was associated with attenuated cortisol responses to stress and determine whether the type of maltreatment was a determinant of the stress response. METHODS Salivary cortisol response to the Trier Social Stress Test (TSST) was examined in a non-clinical sample of women (n = 110). Subjects had no acute medical problems and were not seeking psychiatric treatment. Effects of five maltreatment types, as measured by the Childhood Trauma Questionnaire, on cortisol response to the TSST were investigated. To further examine the significant (p < 0.005) effect of one maltreatment type, women with childhood physical abuse (PA) (n = 20) were compared to those without past PA (n = 90). RESULTS Women reporting childhood PA displayed a significantly blunted cortisol response to the TSST compared with subjects without PA, after controlling for estrogen use, age, other forms of maltreatment, and other potential confounds. There were no differences between PA and control groups with regard to physiological arousal during the stress challenge. CONCLUSIONS In a non-clinical sample of women with minimal or no current psychopathology, physical abuse is associated with a blunted cortisol response to a psychosocial stress task.

Abstract
The professional behavior of scientists, for good or ill, is likely associated with their perceptions of whether they are treated fairly in their work environments, including their academic department and university and by relevant regulatory bodies. These relationships may also be influenced by their own personal characteristics, such as being overcommitted to their work, and by the interactions between these factors. Theory also suggests that such associations may be mediated by negative or positive affect. We examined these issues using data from a national, mail-based survey administered in 2006 and 2007 to 5,000 randomly selected faculty from biomedical and social science departments at 50 top-tier research universities in the United States. We found that perceptions of justice in one's workplace (organizational justice) are positively associated with self-report of "ideal" behaviors and negatively associated with self-report of misbehavior and misconduct. By contrast, researchers who perceive that they are being unfairly treated are less likely to report engaging in "ideal" behaviors and more likely to report misbehavior and misconduct. Overcommitment to one's work is also associated with negative affect and interacts with perceptions of unfair treatment in ways that are associated with higher self-report of misbehavior. Thus, perceptions of fair treatment in the work environment appear to play important roles in fostering-or undermining-research integrity.
