Abstract
OBJECTIVE Psychological distress may contribute to chronic activation of acute-phase inflammation. The current study investigated how financial stressors influence psychosocial functioning and inflammation. This study examined a) the direct relations between financial stress and inflammation; b) whether the relationships between financial stress and inflammation are mediated in part by negative interpersonal events, psychological distress, and psychological well-being; and c) whether social standing in one's community moderates the relations between financial stress and psychological distress, psychological well-being, and markers of inflammation (interleukin-6 [IL-6] and C-reactive protein). METHODS Stressful financial and interpersonal events over the previous year, perceived social status, indices of psychological well-being and distress, and levels of IL-6 and C-reactive protein were assessed in a community sample of 680 middle-aged adults (ages 40-65 years). RESULTS Structural equation modeling analyses revealed significant relations among financial stress, interpersonal stress, and psychological distress and well-being, and complex relationships between these variables and inflammatory markers. Psychological well-being mediated the association between financial stress and IL-6 ([mediation] ab = 0.012, standard error [SE] = 0.006, p = .048). Furthermore, individuals with higher perceived social standing within their communities exhibited a stronger relation between negative financial events and both interpersonal stressors (interaction B = 0.067, SE = 0.017, p < .001) and C-reactive protein (interaction B = 0.051, SE = 0.026, p = .050). CONCLUSIONS Financial stress demonstrates complex relations with inflammation, due partly to psychological well-being and social perceptions. Findings are discussed with regard to the social context of stress and physiological factors pertinent to stress adaptation and inflammation.

[PMID: 26759643 PMCID: PMC4703144 DOI: 10.5811/westjem.2015.9.27945] [Citation(s) in RCA: 137] [Impact Index Per Article: 15.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2015] [Revised: 09/03/2015] [Accepted: 09/24/2015] [Indexed: 11/11/2022] Open
Abstract
INTRODUCTION Burnout is a syndrome of depersonalization, emotional exhaustion and sense of low personal accomplishment. Emergency physicians (EPs) experience the highest levels of burnout among all physicians. Burnout is associated with greater rates of self-reported suboptimal care among surgeons and internists. The association between burnout and suboptimal care among EPs is unknown. The objective of the study was to evaluate burnout rates among attending and resident EPs and examine their relationship with self-reported patient care practices. METHODS In this cross-sectional study burnout was measured at two university-based emergency medicine residency programs with the Maslach Burnout Inventory. We also measured depression, quality of life (QOL) and career satisfaction using validated questionnaires. Six items assessed suboptimal care and the frequency with which they were performed. RESULTS We included 77 out of 155 (49.7%) responses. The EP burnout rate was 57.1%, with no difference between attending and resident physicians. Residents were more likely to screen positive for depression (47.8% vs 18.5%, p=0.012) and report lower QOL scores (6.7 vs 7.4 out of 10, p=0.036) than attendings. Attendings and residents reported similar rates of career satisfaction (85.2% vs 87.0%, p=0.744). Burnout was associated with a positive screen for depression (38.6% vs 12.1%, p=0.011) and lower career satisfaction (77.3% vs 97.0%, p=0.02). EPs with high burnout were significantly more likely to report performing all six acts of suboptimal care. CONCLUSION A majority of EPs demonstrated high burnout. EP burnout was significantly associated with higher frequencies of self-reported suboptimal care. Future efforts to determine if provider burnout is associated with negative changes in actual patient care are necessary.

Abstract
INTRODUCTION In a healthy organization, psychological health and physical health are as important as production and productivity; and healthy workers have higher productivity. Regarding lack of information about workers' general health profile in Qom Province, this study aimed to assess and compare the staffs' general health and its components among different workplaces in 2014. METHODS In a cross-sectional study, 2,276 employees working at 46 industries and organizations completed a standardized General Health Questionnaire (GHQ 28) and a demographic questionnaire. Data were analyzed using t-test, ANOVA, and Pearson product-moment correlation coefficient by IBM SPSS version 20. RESULTS The mean age of the participants was 32.22 (±7.55) years. Seventy-nine point four percent of participants were married and the rest were single. Highest and lowest scores belonged to social dysfunction and depression, respectively. Also, total score of staffs' general health was 17.87 ± 10.93. The results showed that, in spite of the non-relationship between general health score difference among married and single personnel (p > 0.05), there was a significant difference between men and women and among organizations and industries with regards to general health score (p < 0.05), and drivers had the most difference with others. The relationship between workers' ages and GH was significant (p < 0.05, Pearson's bivariate correlation coefficient = -0.05). CONCLUSION The findings of this study collectively indicated that participants had an acceptable condition for mental factors, such as depression, but not in viewpoints of social dysfunction. In other words, staffs' interfaces with circumstances and personal innovation/creativity in the workplaces are at risk. Altogether, the general health score in the studied population was suitable in its entirety.

Abstract
Cardiovascular disease (CVD) remains a leading cause of death worldwide and identification and therapeutic modulation of all its risk factors is necessary to ensure a lower burden on the patient and on society. The physiological response to acute and chronic stress exposure has long been recognized as a potent modulator of immune, endocrine and metabolic pathways, however its direct implications for cardiovascular disease development, progression and as a therapeutic target are not completely understood. More and more attention is given to the bidirectional interaction between psychological and physical health in relation to cardiovascular disease. With atherosclerosis being a chronic disease starting already at an early age the contribution of adverse early life events in affecting adult health risk behavior, health status and disease development is receiving increased attention. In addition, experimental research into the biological pathways involved in stress-induced cardiovascular complications show important roles for metabolic and immunologic maladaptation, resulting in increased disease development and progression. Here we provide a concise overview of human and experimental animal data linking chronic and acute stress to CVD risk and increased progression of the underlying disease atherosclerosis.

Abstract
OBJECTIVES The purpose of this study was to examine the overlap in burnout and depression. METHOD The sample comprised 1,386 schoolteachers (mean [M]age = 43; Myears taught = 15; 77% women) from 18 different U.S. states. We assessed burnout, using the Shirom-Melamed Burnout Measure, and depression, using the depression module of the Patient Health Questionnaire. RESULTS Treated dimensionally, burnout and depressive symptoms were strongly correlated (.77; disattenuated correlation, .84). Burnout and depressive symptoms were similarly correlated with each of 3 stress-related factors, stressful life events, job adversity, and workplace support. In categorical analyses, 86% of the teachers identified as burned out met criteria for a provisional diagnosis of depression. Exploratory analyses revealed a link between burnout and anxiety. CONCLUSIONS This study provides evidence that past research has underestimated burnout-depression overlap. The state of burnout is likely to be a form of depression. Given the magnitude of burnout-depression overlap, treatments for depression may help workers identified as "burned out."

Abstract
OBJECTIVE Dehydroepiandrosterone sulphate (DHEA-s) is an anabolic protective hormone. We have previously reported that DHEA-s production capacity is attenuated in stressed individuals. The aim of the present study was to investigate the DHEA-s response during acute psychosocial stress in patients with clinical burnout. METHODS Seventeen patients with clinical burnout were compared to 13 non-chronically stressed healthy controls, aged 31-50 years (mean age 41 years, SD 6 years), as they underwent the Trier Social Stress Test (TSST). All patients fulfilled diagnostic criteria for stress-related exhaustion disorder, which is a criteria-based diagnosis that has been used in Sweden since 2005 to define patients seeking health-care for clinical burnout. Blood samples were collected before, directly after the stress test, and after 30 min of recovery. DHEA-s levels were measured and delta values (peak levels minus baseline levels) plus area under the curve with respect to increase (AUCI) were calculated. RESULTS The patients had 43% smaller AUCI DHEA-s (p=0.041) during the stress test. The delta DHEA-s was 34% lower in the patients, however, this difference was not statistically significant (p=0.054). CONCLUSION The study indicates that DHEA-s production capacity during acute stress may be attenuated in patients with clinical burnout. Reduced DHEA-s production may constitute one of the links between stress, burnout and the associated adverse health.

Abstract
This study explored whether physical activity and sleep, combined with the biomarker C-reactive protein, indexed positive health in older men. Many were former prisoners of war, with most remaining psychologically resilient and free of any psychiatric diagnoses. Activity and sleep were recorded through actigraphy in 120 veterans (86 resilient and 34 nonresilient) for 7 days. Resilient men had higher physical activity, significantly lower C-reactive protein levels, and 53 percent had lower cardiac-disease risk compared to nonresilient men. Sleep was adequate and not associated with C-reactive protein. Results suggest continued study is needed in actigraphy and C-reactive protein as means to index positive health.

Abstract
INTRODUCTION Burnout can create problems in every aspect of individual's' human life. It may have an adverse effect on interpersonal and family relations and can lead to a general negative attitude towards life. AIM The purpose of this study is to investigate whether burnout is associated with the mental health status of health care providers. MATERIAL AND METHODS The sample in this study consisted of 240 health care employees. The Greek version of Maslach's Burnout Inventory (MBI) was used for measuring burnout levels and the Greek version of the Symptoms Rating Scale for Depression and Anxiety (SRSDA) questionnaire was used to evaluate health care providers' mental health status. Descriptive statistics were initially generated for sample characteristics. Normality was checked by the Kolmogorov-Smirnov test and data was processed with parametric tests. General linear models with MBI dimensions as independent variables and SRSDA subscales as dependent variables were used to determine the relation between burnout and mental health status. Statistics were processed with SPSS v. 17.0 (SPSS, Chicago, IL, USA). Statistical significance was set at p=0.05. RESULTS The average age of the sample is 40.00±7.95 years. Regarding gender the percentage of men is 21.40% (N=49) and of women is 78.60% (N=180). Overall the professional burnout of health care workers is moderate. The mean score for emotional exhaustion is 26.41, for personal accomplishment 36.70 and for depersonalization 9.81. The mean for each subscale of SRSDA is 8.23±6.79 for Depression Beck-21, 3.96±4.26 for Depression Beck-13, 4.91±4.44 for Melancholia, 6.32±4.35 for Asthenia and 6.36±4.72 for Anxiety. The results of general linear models with the MBI dimensions as independent variables and the SRSDA subscales as dependent variables are shown that emotional exhaustion and personal accomplishment are statistically correlated with all subscales of SRSDA, while depersonalization is not correlated with any SRSDA subscale. CONCLUSIONS Burnout appears to implicate mental health status of healthcare providers in work index. Emotional exhaustion is the burnout dimension that is correlated the most with employees' mental health.

Abstract
Whether burnout is a form of depression or a distinct phenomenon is an object of controversy. The aim of the present article was to provide an up-to-date review of the literature dedicated to the question of burnout-depression overlap. A systematic literature search was carried out in PubMed, PsycINFO, and IngentaConnect. A total of 92 studies were identified as informing the issue of burnout-depression overlap. The current state of the art suggests that the distinction between burnout and depression is conceptually fragile. It is notably unclear how the state of burnout (i.e., the end stage of the burnout process) is conceived to differ from clinical depression. Empirically, evidence for the distinctiveness of the burnout phenomenon has been inconsistent, with the most recent studies casting doubt on that distinctiveness. The absence of consensual diagnostic criteria for burnout and burnout research's insufficient consideration of the heterogeneity of depressive disorders constitute major obstacles to the resolution of the raised issue. In conclusion, the epistemic status of the seminal, field-dominating definition of burnout is questioned. It is suggested that systematic clinical observation should be given a central place in future research on burnout-depression overlap.

Abstract
Irritable bowel syndrome (IBS) is regarded as a multifactorial disease in which alterations in the brain-gut axis signaling play a major role. The biopsychosocial model applied to the understanding of IBS pathophysiology assumes that psychosocial factors, interacting with peripheral/central neuroendocrine and immune changes, may induce symptoms of IBS, modulate symptom severity, influence illness experience and quality of life, and affect outcome. The present review focuses on the role of negative affects, including depression, anxiety, and anger, on pathogenesis and clinical expression of IBS. The potential role of the autonomic nervous system, stress-hormone system, and immune system in the pathophysiology of both negative affects and IBS are taken into account. Psychiatric comorbidity and subclinical variations in levels of depression, anxiety, and anger are further discussed in relation to the main pathophysiological and symptomatic correlates of IBS, such as sensorimotor functions, gut microbiota, inflammation/immunity, and symptom reporting.

Abstract
OBJECTIVE To assess job stress, burnout, and job satisfaction in patients with obstructive sleep apnea syndrome (OSAS). METHODS A total of 182 patients with OSAS and 71 healthy individuals completed the Job Content Questionnaire, the Maslach Burnout Inventory - General Survey, the Index of Job Satisfaction, the Epworth Sleepiness Scale, and the Pittsburgh Sleep Quality Index. All participants were assessed with full-night polysomnography. RESULTS Survey scores of patients diagnosed with OSAS only differed from those of the control group in the emotional exhaustion dimension (P = 0.015). According to a multivariate analysis, the apnea-hypopnea index (AHI) was only correlated with perceived support at work (β coefficient = 0.142; P = 0.048). Associations were found between subjective sleep quality, perceived support from coworkers, and supervisors (β = 0.157; P = 0.025), psychological demands (β = 0.226; P = 0.001), emotional exhaustion (β = 0,405; P = 0.000), and cynicism (β = 0.224; P = 0.002). The study also revealed associations between excessive daytime sleepiness and the burnout dimensions emotional exhaustion (β = 0.232; P = 0.000) and cynicism (β = 0.139; P = 0.048). CONCLUSION Objective parameters of OSAS such as the AHI seem to have limited influence on the psychosocial aspects of the occupational life of patients with OSAS. There is evidence of significant associations between the subjective symptoms of the disease, such as daytime sleepiness, subjective sleep quality, job stress, and burnout.

Abstract
OBJECTIVE Prolactin levels have been shown to be increased by different types of psychosocial stress. Since burnout is a consequence of long-term psychosocial stress, prolactin levels might also be affected in burnout. The aim of this study was to investigate whether there are differences in prolactin levels between individuals who report burnout and others. METHOD Morning fasting serum prolactin levels were compared between individuals who reported burnout (24 men and 25 women) and individuals who reported no burnout (25 men and 13 women). Women were tested in the follicular phase of the menstrual cycle. Men and women were analysed separately. RESULTS Men who reported burnout exhibited significantly higher (34%) serum prolactin levels compared to men who reported no burnout. The prolactin levels in women who reported burnout were not different from the levels in the women who reported no burnout before or after adjusting for estradiol levels. CONCLUSIONS This study indicates that prolactin levels are higher in men with burnout than men without burnout but not affected in women with burnout. Why no association was seen in women needs to be further explored.

Abstract
The obesity epidemic and associated chronic diseases are often attributed to modern lifestyles. The term "lifestyle" however, ignores broader social, economic, and environmental determinants while inadvertently "blaming the victim." Seen more eclectically, lifestyle encompasses distal, medial, and proximal determinants. Hence any analysis of causality should include all these levels. The term "anthropogens," or "…man-made environments, their by-products and/or lifestyles encouraged by these, some of which may be detrimental to human health" provides a monocausal focus for chronic diseases similar to that which the germ theory afforded infectious diseases. Anthropogens have in common an ability to induce a form of chronic, low-level systemic inflammation ("metaflammation"). A review of anthropogens, based on inducers with a metaflammatory association, is conducted here, together with the evidence for each in connection with a number of chronic diseases. This suggests a broader view of lifestyle and a focus on determinants, rather than obesity and lifestyle per se as the specific causes of modern chronic disease. Under such an analysis, obesity is seen more as "a canary in a mineshaft" signaling problems in the broader environment, suggesting that population obesity management should be focused more upstream if chronic diseases are to be better managed.

Abstract
Psychosocial stress is an important precursor of disease and reduced quality of life in humans. The biological pathways between stress exposure and pathophysiological processes underlying disease have received substantial scientific attention, although the roles of the hypothalamic-pituitary-adrenal axis and sympathetic nervous system remain insufficiently understood. Recent attention has focused on chronic systemic low-grade inflammation as a promising pathway because elevated inflammation often accompanies chronic psychosocial distress. These alterations of inflammatory activity play a key role in the pathophysiology of diseases that are adversely affected by chronic distress, such as cardiovascular disease. Transient increases in systemic inflammation are observed in response to acute psychosocial stress, with larger responses among individuals reporting adverse psychosocial states or conditions such as depression, lower self-esteem, or lower self-compassion. Recent evidence shows that lower subjective social status and perceived purpose in life are associated with sensitization of inflammatory stress responses to repeated stress exposure. The aims of this selective review article are to summarize current knowledge of the role of acute and chronic psychosocial stress on low-grade inflammation in humans and to discuss potential relationships between inflammatory responses to acute psychosocial stress and long-term development of disease.

Abstract
Background The training to become a dentist can create psychological distress. The present study evaluates the structure of the ‘Perceived Stress Questionnaire’ (PSQ), its internal consistency model and interrelatedness with burnout, anxiety, depression and resilience among dental students. Methods The study employed a cross-sectional design. A sample of Spanish dental students (n = 314) completed the PSQ, the ‘Goldberg Anxiety and Depression Scale’ (GADS), ‘Connor-Davidson Resilience Scale’ (10-item CD-RISC) and ‘Maslach Burnout Inventory-Student Survey’ (MBI-SS). The structure was estimated using Parallel Analysis from polychoric correlations. Unweighted Least Squares was the method for factor extraction, using the Item Response Theory to evaluate the discriminative power of items. Internal consistency was assessed by squaring the correlation between the latent true variable and the observed variable. The relationships between the PSQ and the other constructs were analysed using Spearman’s coefficient. Results The results showed a PSQ structure through two sub-factors (‘frustration’ and ‘tenseness’) with regard to one general factor (‘perceived stress’). Items that did not satisfy discriminative capacity were rejected. The model fit were acceptable (GFI = 0.98; RSMR = 0.06; AGFI = 0.98; NFI = 0.98; RFI = 0.98). All the factors showed adequate internal consistency as measured by the congeneric model (≥0.91). High and significant associations were observed between perceived stress and burnout, anxiety, depression and resilience. Conclusions The PSQ showed a hierarchical bi-factor structure among Spanish dental students. Using the questionnaire as a uni-dimensional scale may be useful in perceived stress level discrimination, while the sub-factors could help us to refine perceived stress analysis and improve therapeutic processes.

Abstract
Background Cognitive functioning is important for managing work and life in general. However, subjective cognitive complaints (SCC), involving perceived difficulties with concentration, memory, decision making, and clear thinking are common in the general and working population and can be coupled with both lowered well-being and work ability. However, the relation between SCC and cognitive functioning across the adult age-span, and in the work force, is not clear as few population-based studies have been conducted on non-elderly adults. Thus, the present study aimed to test the relation between SCC and executive cognitive functioning in a population-based sample of employees. Methods Participants were 233 employees with either high (cases) or low (controls) levels of SCC. Group differences in neuropsychological test performance on three common executive cognitive tests were analysed through a set of analyses of covariance tests, including relevant covariates. Results & Conclusions In line with the a priori hypotheses, a high level of SCC was associated with significantly poorer executive cognitive performance on all three executive cognitive tests used, compared to controls with little SCC. Additionally, symptoms of depression, chronic stress and sleeping problems were found to play a role in the relations between SCC and executive cognitive functioning. No significant associations remained after adjusting for all these factors. The current findings contribute to an increased understanding of what characterizes SCC in the work force and may be used at different levels of prevention of- and intervention for SCC and related problems with executive cognitive functioning.

Abstract
INTRODUCTION C-reactive protein (CRP) is an acute-phase reactant with an increasing number of clinical functions. Studies in recent years have identified several social, economic, demographic, and psychological factors that contribute to baseline inflammation. Psychosocial stress represents a significant contributor to baseline inflammation. Given the importance of understanding background drivers of CRP levels, we conducted this review to assess the impact of chronic psychosocial stress on CRP levels. METHODS Medline was searched through February 2013 for human studies examining CRP levels with respect to chronic psychosocial stress. RESULTS The initial search identified 587 articles from which 129 potentially appropriate articles were reviewed. Of these 129 articles, 41 articles were included in the review. These studies were published between 2003 and 2013. Of these studies, 6 analyzed employment stress, 2 analyzed unemployment stress, 6 analyzed burnout and vital exhaustion, 6 analyzed caregiver stress, 3 analyzed interpersonal stress, 17 analyzed socioeconomic position, and 2 analyzed discrimination. CONCLUSION We conclude that psychosocial stress significantly impacts CRP and should be considered when interpreting the meaning of CRP elevations.

Abstract
Chronic disease epidemiology currently lacks the mono-causal focus germ theory provides infectious diseases. However, the discovery of a form of low-grade, systemic, and chronic inflammation (“metaflammation) underlying many, if not all, chronic diseases induced by a range of stimulants labeled “anthropogens” may help change this. Anthropogens are “man-made environments, their by-products, and/or lifestyles encouraged by these, some of which are detrimental to human health.” While an exhaustive list of anthropogens associated with chronic disease may be as elusive as a comprehensive list of “germs” with the potential to cause infection, a broad taxonomy provides a focus for the practice of lifestyle medicine. Such a list is considered here under the acronym NASTIE ODOURS.

Abstract
Within occupational health research, one of the most influential models is the Job Demands-Control-Support model. Numerous studies have applied the model to different domains, with both physical and psychological health outcomes, such as burnout. The twin design provides a unique and powerful research methodology for examining the effects of environmental risk factors on burnout while taking familial factors (genetic and shared environment) into account. The aim of the present study was to investigate the impact of familial factors on the associations of burnout with job demands, control and support. A total of 14 516 individuals from the Swedish Twin Registry, who were born between 1959 and 1986, and who participated in the Study of Twin Adults: Genes and Environment (STAGE) by responding to a web-based questionnaire in 2005, were included in the analyses. Of these, there were 5108 individuals in complete same-sex twin pairs. Co-twin control analyses were performed using linear mixed modeling, comparing between-pairs effects and within-pair effects, stratified also by zygosity and sex. The results indicate that familial factors are of importance in the association between support and burnout in both women and men, but not between job demands and burnout. There are also tendencies towards familial factors being involved in the association between control and burnout in men. These results offer increased understanding of the mechanisms involved in the associations between work stress and burnout.

Abstract
Fatigue is a main feature of the burnout syndrome but also very common in other psychiatric disorders such as major depression and anxiety disorders. This raises the question of whether the level and appraisal of fatigue is experienced differently by individuals suffering from burnout than by those exhibiting anxiety disorders and major depression. If fatigue is experienced differently in burnout compared with other disorders, this may clarify why fatigue is the main feature of the burnout syndrome. This knowledge may lead to the application of specific therapeutic interventions aimed at the experience of fatigue in burnout. In the present study, we investigated whether fatigue is experienced differently in burnout patients than in patients suffering from anxiety disorders or major depression. We presented 73 burnout patients, 67 depressed patients, 57 patients with an anxiety disorder and 127 healthy participants with a rating scale containing statements about the fatigue-performance relationship, and we assessed the level of fatigue, depression and anxiety. The level of fatigue reported by burnout patients was high but did not differ from that of the other patient groups. The appraisal of fatigue also did not differ among the patient groups. The burnout patients did not appraise their fatigue as a result of unrewarding activities nor did they catastrophize fatigue in an exceptional way. Thus, the level of fatigue and the appraisal of fatigue may be less relevant to the understanding of the specific pathological processes associated with burnout than is often presumed.

Abstract
BACKGROUND The evidence supporting a relationship between stress and diabetes has been inconsistent. PURPOSE This study examined the effects of stress on abnormal glucose metabolism, using a population-based sample of 3,759, with normoglycemia at baseline, from the Australian Diabetes, Obesity and Lifestyle study. METHODS Perceived stress and stressful life events were measured at baseline, with health behavior and anthropometric information also collected. Oral glucose tolerance tests were undertaken at baseline and 5-year follow-up. The primary outcome was the development of abnormal glucose metabolism (impaired fasting glucose, impaired glucose tolerance, and type 2 diabetes), according to WHO 1999 criteria. RESULTS Perceived stress predicted incident abnormal glucose metabolism in women but not men, after multivariate adjustment. Life events showed an inconsistent relationship with abnormal glucose metabolism. CONCLUSIONS Perceived stress predicted abnormal glucose metabolism in women. Healthcare professionals should consider psychosocial adversity when assessing risk factor profiles for the development of diabetes.

Abstract
BACKGROUND AND PURPOSE Growing scientific evidence indicates that there is a correlation between depression and alternations in the immune system. The main aim of the study was to investigate serum levels of Interleukin-6 (IL-6) and Tumour Necrosis Factor-alpha (TNF-α) in melancholic and atypical depressive patients during acute exacerbations of illness, compared to healthy subjects. The secondary aim was to explore a possible association between cytokine levels and clinical characteristics, as well as total duration of prior antidepressant treatment. METHOD We measured serum levels of IL-6 and TNF-α in 47 patients suffering from major depressive disorder (MDD) (29 melancholic and 18 atypical) in exacerbation of illness, compared to 39 healthy controls, matched by sex, body mass index (BMI) and smoking habits. Serum levels of IL-6 and TNF-α were measured by enzyme-linked immunosorbent assay (ELISA). The severity of psychopathology was assessed using the Hamilton Depression Rating Scale (HDRS). RESULTS IL-6 was significantly elevated in melancholic depressive patients (MDD-M) compared to healthy controls, while no difference was found between the patients with atypical depression (MDD-A) and the healthy group. Lower TNF-α serum level was found both in melancholic and in patients with atypical depression, compared with healthy subjects. We detected a positive correlation between cytokine levels in atypical, but not in melancholic subjects. Sex, age, smoking habits and BMI were not associated to cytokine levels in neither group. Clinical parameters (duration of illness, current episode, age of onset) were related to cytokine levels in atypical depression, while the duration of lifetime exposure to antidepressant treatment correlated to IL-6 serum levels in both melancholic and atypical depression. CONCLUSION Our results suggest that the difference in pro-inflammatory cytokine levels could reflect a biological difference between melancholic and atypical depression. A positive correlation between the cytokines (TNF-α and IL-6) observed in depressive patients with atypical features, might be influenced by chronic course of illness, while IL-6 elevation could represent a state indicator for acute exacerbation, especially in melancholic patients. Total duration of antidepressant treatment could be a relevant factor influencing the immune status of patients who suffer either from melancholic or atypical depression.

Abstract
The increased prevalence and high comorbidity of metabolic syndrome (MetS) and mental health disorders (MHDs) have prompted investigation into the potential contributing mechanisms. There is a bidirectional association between MetS and MHDs including schizophrenia, bipolar disorder, depression, anxiety, attention-deficit/hyperactivity disorder, and autism spectrum disorders. Medication side effects and social repercussions are contributing environmental factors, but there are a number of shared underlying neurological and physiological mechanisms that explain the high comorbidity between these two disorders. Inflammation is a state shared by both disorders, and it contributes to disruptions of neuroregulatory systems (including the serotonergic, dopaminergic, and neuropeptide Y systems) as well as dysregulation of the hypothalamic-pituitary-adrenal axis. MetS in pregnant women also exposes the developing fetal brain to inflammatory factors that predispose the offspring to MetS and psychopathologies. Due to the shared nature of these conditions, treatment should address aspects of both mental health and metabolic disorders. Additionally, interventions that can interrupt the transfer of increased risk of the disorders to the next generation need to be developed. © 2013 S. Karger AG, Basel.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is highly co-morbid with depression. Depression is associated with elevated levels of the inflammation marker C-reactive protein (CRP), cross-sectionally and over time. To date, no studies have looked at the association between CRP and GAD. METHOD A total of nine waves of data from the prospective population-based Great Smoky Mountains Study (n=1420) were used, covering children in the community aged 9-16, 19 and 21 years old. Structured interviews were used at each assessment to assess GAD symptoms, diagnosis and cumulative episodes. Blood spots were collected and assayed for high-sensitivity CRP levels. RESULTS GAD was associated with increased levels of CRP in bivariate cross-sectional analyses. These bivariate associations, however, were attenuated after accounting for demographic, substance-use and health-related covariates. In longitudinal models, there was little evidence that CRP predicted later GAD. Associations from GAD to later CRP were attenuated in models adjusted for health-related coavariates and there was evidence that the GAD-CRP association was mediated by body mass index (BMI) and medication use. CONCLUSIONS Similar to depression, GAD was associated with elevated levels of CRP, but the effect of GAD on CRP levels was explained by the effect of GAD on health-related behaviors such as BMI and medication use. This study suggests differences in the association between inflammation and depression and GAD.

Abstract
The environment that a developing offspring experiences during the perinatal period is markedly influenced by maternal health and diet composition. Evidence from both epidemiological studies and animal models indicates that maternal diet and metabolic status play a critical role in programming the neural circuitry that regulates behavior, resulting in long-term consequences for offspring behavior. Maternal diet and metabolic state influence the behavior of offspring directly by impacting the intrauterine environment and indirectly by modulating maternal behavior. The mechanisms by which maternal diet and metabolic profile shape the perinatal environment remain largely unknown, but recent research has found that increases in inflammatory cytokines, nutrients (glucose and fatty acids), and hormones (insulin and leptin) affect the environment of the developing offspring. Offspring exposed to maternal obesity and high fat diet consumption during development are more susceptible to developing mental health and behavioral disorders such as anxiety, depression, attention deficit hyperactivity disorder, and autism spectrum disorders. Recent evidence suggests that this increased risk for behavioral disorders is driven by modifications in the development of neural pathways involved in behavioral regulation. In particular, research indicates that the development of the serotonergic system is impacted by exposure to maternal obesity and high fat diet consumption, and this disruption may underlie many of the behavioral disturbances observed in these offspring. Given the high rates of obesity and high fat diet consumption in pregnant women, it is vital to examine the influence that maternal nutrition and metabolic profile have on the developing offspring.

Abstract
OBJECTIVE Burnout is a negative affective state consisting of emotional exhaustion, physical fatigue, and cognitive weariness symptoms. This study was designed to evaluate prospectively the association between burnout and coronary heart disease (CHD) incidence and to test the possibility that this association is nonlinear. METHODS Participants were 8838 apparently healthy employed men and women, aged 19 to 67 years, who came for routine health examinations at the Tel Aviv Sourasky Medical Center. They were followed up for 3.4 years on average. Burnout was measured by the Shirom-Melamed Burnout Measure. CHD incidence was defined as a composite of acute myocardial infarction, diagnosed ischemic heart disease, and diagnosed angina pectoris. RESULTS During follow-up, we identified 93 new cases of CHD. Baseline levels of burnout were associated with an increased risk of CHD, after adjustment for various risk factors (hazard ratio = 1.41; 95% confidence interval = 1.08-1.85). In addition, we observed a significant threshold effect of burnout on CHD incidence. Participants who scored high on burnout (scores in the upper quintile of the Shirom-Melamed Burnout Measure scores distribution) had a higher risk (hazard ratio = 1.79; 95% confidence interval = 1.05-3.04) of developing CHD on follow-up compared with others. CONCLUSIONS Burnout is an independent risk factor for future incidence of CHD. Individuals with high levels of burnout (upper quintile) have a significantly higher risk of developing CHD compared with those with low levels of burnout.

Abstract
We examined the effects of burnout and vigor on the incidence of hyperlipidemia. Based on the bivariate theoretical approach to negative and positive affects and on past studies on the prediction of blood lipids by burnout and vigor, we expected increases from Time 1 (T1) to Time 2 (T2) in burnout levels to be associated with an increase in the risk for hyperlipidemia and T1-T2 increases in vigor levels to be associated with a decrease in the risk of hyperlipidemia. Our sample consisted of 3,337 healthy employees (2,214 men and 1,123 women) who were followed up for about 27 months on average. Burnout and vigor were assessed by well-validated multiple-item instruments. We used logistic regressions and controlled for variables associated with blood lipids as well as with vigor and burnout. We cross-validated all self-reported hyperlipidemia by their T2 lipids levels. As expected, we found that T1-T2 increases in vigor levels were associated with a decreased risk of hyperlipidemia. However, the T1-T2 change in burnout levels was marginally significant (p = .06) in predicting hyperlipidemia. We consider our finding that vigor and burnout are independently associated with the risk of hyperlipidemia as providing support for the bivariate approach to affective states. In addition, our major finding suggests a possible mechanism via which vigor influences physical health outcomes.

Abstract
Burnout is widely known as a work-related syndrome that is associated by serious individual and social consequences. The aim of the HTA report "Differential diagnostic of the burnout syndrome" published by DIMDI in 2010 was to determine how burnout can be diagnosed and distinguished from other disorders. Based on a systematic literature review of 36 databases, 852 studies published between 2004 and 2009 were identified. After considering inclusion and exclusion criteria, 25 medical and one ethical study remained. The study evidence is predominantly low. Self-assessment tools are mainly used. The analysis showed that no standardized, common valid procedure exists to obtain a burnout diagnosis. Overall the problem is to measure a phenomenon that is not exactly defined. It is primarily important to distinguish burnout from depression, alexithymia, feeling unwell, and the concept of prolonged exhaustion. Beside the need for a valid definition, further research is needed, particularly high-quality, long-term studies, to broaden the understanding of the syndrome. Furthermore, a standardized, internationally accepted and valid procedure for diagnosing burnout is necessary.

Innstrand ST, Langballe EM, Falkum E. A longitudinal study of the relationship between work engagement and symptoms of anxiety and depression. Stress Health 2012; 28:1-10.

Abstract
This longitudinal study examined the dynamic relationship between work engagement (vigour and dedication) and symptoms of anxiety and depression. A sample of 3475 respondents from eight different occupational groups (lawyers, physicians, nurses, teachers, church ministers, bus drivers, people working in advertising and people working in information technology) in Norway supplied data at two points in time with a 2-year time interval. The advantages of longitudinal design were utilized, including testing of reversed causation and controlling for unmeasured third variables. In general, the results showed that the hypothesized normal causal relationship was superior to a reversed causation model. In other words, this study supported the assumption that work engagement is more likely to be the antecedent for symptoms of depression and anxiety than the outcome. In particular, the vigour facet of work engagement provides lower levels of depression and anxiety 2 years later. However, additional analyses modelling unmeasured third variables indicate that unknown third variables may have created some spurious effects on the pattern of the observed relationship. Implications of the findings are discussed in the paper.

Abstract
The purpose of this review was to provide current knowledge about the possible association between psychosocial job stress and immune parameters in blood, saliva, and urine. Using bibliographic databases (PubMed, PsychINFO, Web of Science, Medline) and the snowball method, 56 studies were found. In general, exposure to psychosocial job stress (high job demands, low job control, high job strain, job dissatisfaction, high effort-reward imbalance, overcommitment, burnout, unemployment, organizational downsizing, economic recession) had a measurable impact on immune parameters (reduced NK cell activity, NK and T cell subsets, CD4+/CD8+ ratio, and increased inflammatory markers). The evidence supports that psychosocial job stresses are related to disrupted immune responses but further research is needed to demonstrate cause-effect relationships.

Abstract
OBJECTIVE Although fatigue is a common complaint in the working population, underlying immunological mechanisms are not well understood. This study investigated the association of general fatigue with cellular immune indicators. METHODS A total of 148 healthy white-collar employees (70% men) underwent a blood draw for the measurement of natural killer (NK), B, and T cell counts as well as NK cell cytotoxicity (NKCC) and completed two different fatigue scales, that is, Profile of Mood State (POMS) and Maastricht Questionnaire (MQ). RESULTS Multiple linear regression analyses revealed that POMS fatigue score was significantly associated with decreases of NK cells (β = -.407) and NKCC (β = -.215), whereas MQ fatigue score was significantly associated with reduced NK cells (β = -.290) but not with NKCC (β = -.127). CONCLUSION The results suggest that general fatigue may be related to impaired NK cell competency among healthy employees.

Abstract
BACKGROUND Burnout is a stress state characterized by symptoms of mental exhaustion and physical fatigue, detachment from work, and feelings of diminished competence. Several biomarkers have been tested for association with burnout, but the results are conflicting. AIM The objective of this review was to identify potential biomarkers for burnout. METHODS We carried out a systematic review of studies comparing biomarkers in individuals with burnout and healthy controls, or individuals with low scores and those with high scores on burnout questionnaires. Literature searches in MEDLINE and EMBASE were performed. We describe biomarkers on which at least three studies were available. Where appropriate, a meta-analysis was carried out. RESULTS We identified 31 studies on 38 biomarkers involved in the hypothalamus-pituitary-adrenal axis, autonomic nervous system, immune system, metabolic processes, antioxidant defense, hormones, and sleep. At least 3 studies were available for cortisol in saliva and blood, blood pressure, heart rate, cholesterol, dehydroepiandrosterone sulfate, (numbers or activity of) natural killer cells, C-reactive protein, and prolactin. The comparability of studies was limited, due to differences in the methods used to characterize patients and controls, to assess biomarkers, and to control for confounders. Furthermore, burnout was operationalized in different ways. Meta-analyses showed no differences for cortisol awakening response and cortisol awakening response after administration of dexamethasone, cortisol in blood, and blood pressure. CONCLUSIONS No potential biomarkers for burnout were found, largely due to the incomparability of studies. We emphasize the need for a dimensional and longitudinal approach in future research to account for the heterogeneity of burnout.

Abstract
OBJECTIVE Few have considered whether and how child emotional functioning is associated with inflammation later in life. Therefore, we evaluated whether child emotional functioning at age 7 years is associated with C-reactive protein (CRP), an indicator of systemic inflammation, in middle adulthood. METHODS We studied adult offspring (mean age 42.2 years) of participants in the National Collaborative Perinatal Project, a national cohort of pregnant women enrolled between 1959 and 1966. Three measures of child emotional functioning were derived from psychologist ratings of child behavior at age 7 years: inappropriate self-regulation (ISR), distress proneness, and behavioral inhibition. Multiple linear regression models were fit to investigate the association between childhood emotional functioning and adulthood CRP and also to evaluate potential mediators of this association. Model n's were from 400 for Model 1 to 379 for Model 4 depending on covariates included and missing data on those covariates. RESULTS Children with high ISR and distress proneness at age 7 years had significantly higher CRP as adults (ISR: β = 0.86; standard error [SE] = 0.28; p = .002; distress proneness: β = 1.23; SE = 0.57; p = .03). In contrast, children with high levels of behavioral inhibition had lower CRP as adults (β = -0.58; SE = 0.38; p = .04). Furthermore, there was evidence that associations of ISR and distress proneness with CRP may be mediated in part by adulthood body mass index (Sobel significance tests of mediation: ISR: p = .003; distress proneness: p = .07). CONCLUSIONS Findings suggest that poor childhood emotional functioning is associated with inflammation in adulthood. These results suggest a potential childhood origin of adult inflammatory risk.

Abstract
Aim. To assess the associations between inflammatory factors and anxiety (A) and depression (D) levels in patients with myocardial infarction (MI). Material and methods. The study included 100 MI patients, hospitalised with a diagnosis of Q-wave MI (mean age 62,0±1,3 years). The methods of psychosocial status assessment included Zung depression scale and SpielbergerKhanin personal and reactive anxiety scales. The inflammatory markers of interest included interleukins (IL) 1-beta, IL-6, IL-8, IL-10, and C-reactive protein (CRP). Results. D and A symptoms in the early post-MI stage were associated with higher risk of cardiovascular events in the following year. Among MI patients with comparable MI severity, D and A symptoms were linked to higher levels of pro-inflammatory cytokines IL-1-beta, IL-8, IL-8, and INF-gamma. Conclusion. In MI patients with D and A symptoms, one of the mechanisms of poor prognosis is an activation of subclinical inflammation.

Abstract
The objective of this study is to examine how chronic stress in major life domains [relationship, work, sympathetic-caregiving, financial] relates to CVD risk, operationalized using the inflammatory marker C-Reactive Protein (CRP), and whether gender differences exist. Participants were 6,583 individuals aged 45-84 years, recruited as part of the Multi-Ethnic Study of Atherosclerosis. Demographic and behavioral factors, health history, and chronic stress were self-reported. CRP was obtained through venous blood draw. In aggregate, gender by chronic stress interaction effects accounted for a significant, albeit small, amount of variance in CRP (P < .01). The sympathetic-caregiving stress by gender interaction was significant (P < .01); the work stress by gender effect approached significance (P = .05). Women with sympathetic-caregiving stress had higher CRP than those without, whereas no difference in CRP by stress group was observed for men. Findings underscore the importance of considering gender as an effect modifier in analyses of stress-CVD risk relationships.

Abstract
OBJECTIVE The aim of this study is to determine the levels of burnout among employees of health care workers in the Health Area of Ceuta (Spain). DESIGN Prevalence study. SETTING Ceuta Health Area (Primary and Specialty Care). PARTICIPANTS A sample of 200 workers stratified by sex, job and workplace. MEASUREMENTS The tool used was the MBI (Maslach Burnout Inventory). We also studied personal (age, sex, marital status) and work variables (centre, job, age) and blood parameters (C-reactive protein and others). RESULTS The burnout syndrome was present in 17.2% of workers (95% CI: 10.4-26.0). There was a significant relationship with job, with differences in emotional exhaustion, depersonalisation, and professional achievement. C-reactive protein was significantly higher in workers with burnout. CONCLUSIONS Burnout prevalence in the health care workers in our sample is similar to other studies. The differences between health and non-health workers could be due to greater motivation for professional achievement, but they scored higher in exhaustion and depersonalisation. The increase in C-reactive protein, a non-specific inflammation marker, seems to confirm the findings of other studies.

Abstract
This study evaluated inflammatory, coagulation and microvascular responses to a continuous 24-h work day in 13 healthy intensive care physicians. Inflammatory markers (interleukin [IL]-2, IL-6, IL-10, tumour necrosis factor-α, matrix metalloproteinase [MMP]-9 and adiponectin), adhesion molecules (vascular cellular adhesion molecule-1 and intercellular adhesion molecule-1 [ICAM-1]), coagulation parameters (thrombin—anti thrombin, von Willebrand factor and tissue factor) and sublingual micro circulation were assessed before and after a 24-h work shift. The 24-h work shift had no effect on inflammatory markers and ICAM-1. Direct visualization of microcirculation did not reveal stress-related perfusion abnormalities. A 24-h work shift in the intensive care unit was associated with significantly increased plasma levels of tissue factor — a potentially important mechanism linking acute job strain, haemostasis and atherosclerosis. The long-term consequences warrant further evaluation.

Abstract
The effects of exposure to terror on physical health were investigated by relating objective exposure to terror and fear of terror to self-rated health (SRH), a proxy measure of health status. Our respondents were apparently healthy (N=4,877, 38% women) adults who completed self-report questionnaires. Objective exposure was assessed by the number of terrorist attacks and their casualties in a respondent's urban area prior to her/his completion of the questionnaire. Using several alternative assessments, objective exposure to terror did not predict SRH for both the genders. As hypothesized, fear of terror negatively predicted SRH for both females and males (beta=-0.04, -0.05, respectively). The effects of subjective and objective exposure were not found to be more pronounced among women relative to men, thus disconfirming our hypotheses in this regard. Our findings suggest that living under continuous fear of terror may adversely influence physical health irrespective of objective exposure.

Abstract
Objective. Depression has been associated with increased cardiovascular disease risk, and a depression-related elevation of high sensitivity C-reactive protein (hs-CRP) has been proposed as a possible mechanism. The objective of this paper is to examine association between depression and high sensitivity C-reactive protein (hs-CRP). Methods. Subjects consisted of 508 healthy adults (mean age 48.5 years; 49% women, 88% white) residing in central Massachusetts. Data were collected at baseline and at quarterly intervals over a one-year period per individual. Multivariable linear mixed models were used to assess the association for the entire sample and by gender. Results. The mean Beck Depression Inventory score was 5.8 (standard deviation (SD) 5.4; median 4.3), and average serum hs-CRP was 1.8 mg/L (SD 1.7; median 1.2). Results from the multivariable linear mixed models show that individuals with higher depression scores have higher levels of hs-CRP. Analyses by gender show persistence of an independent association among women, but not among men. Body mass index (BMI = weight(kg)/height(m)(2)) appears to be a partial mediator of this relationship. Conclusion. Depression score was correlated to hs-CRP levels in women. Further studies are required to elucidate the biological mechanisms underlying these associations and their implications.

Abstract
BACKGROUND/AIM Burnout syndrome as a consequence of a long stress at workplace can seriously disturb health and quality of life in exposed workers. It is necessary to have adequate burnout prevention and its detection. Worldwide much attention is paid to protect burnout and methods for its determination constantly improve. In Serbia there has not been a study of that kind yet. The aim of the study was to investigate burnout syndrome impact on the quality of life of workers in food industry in Nis, and to call attention of researchers in Serbia on this phenomenon, as well as to test probability of applying the original, standardized questionnaires (CBI, ComQolA5) to working population in Serbia. METHODS This study was performed in Nis within a period from 2008 to 2009 in the Institute for Workers Health Protection. A total of 489 workers were included in this study by the use of the standard questionnaire for burnout (CBI) and quality of life (ComQoL-A5). Scale confidence for measuring burnout and quality of life was determined by Cronbach alpha coefficient. ANOVA analysis was used for rating influence of burnout on the quality of life. RESULTS The values of Cronbach alpha coefficient showed a high confidence of the scale for measurement personal burnout (0.87), work-related burnout (0.86) and subjective quality of life (0.83). We detected increased scores as a result of personal burnout (60.0), as well as of work-related burnout (67.9). The workers suggested relationship with the family and friends as a very important part for their quality of life (10.8), health (9.8) and safety (8.0). Productivity (6.8), emotional well-being (6.6) and material property (4.5) had smaller influence on their quality of life. An increase in score of work-related burnout by 1 was statistically significantly related to decreasing inter scores for subjective quality of life in health (B = -0.097), relationship with family and friends (B = -0.048), safety (B = -0.061) and place in community (B = -0.105). A statistically significant relation between work-related burnout and subjective quality of life in productivity, material and emotional well-being was not determined. CONCLUSION There is a high score of both personal and work related burnout among manufacturing workers in food industry. A negative correlation between burnout and subjective quality of life was also proved impacting health and well-being of workers, but also their productivity. The questionnaires we used (CBI, ComQolA5) could be considered as reliable and valid instruments for testing burnout and quality of life in Serbia.

Abstract
Anxiety confers increased risk for inflammatory diseases, and elevated inflammatory activity in anxious individuals may contribute to this increased risk. One complication, however, is that anxiety could be associated with inflammatory activity either through a specific anxiety pathway or through a more general negative emotionality pathway. To investigate, we measured levels of the stress hormone cortisol, the pro-inflammatory cytokine interleukin-6 (IL-6), and the systemic inflammatory marker C-reactive protein (CRP), as well as depression and neuroticism, in clinically anxious and non-anxious adults. Compared with non-anxious participants, clinically anxious participants exhibited significantly lower levels of morning cortisol and significantly higher levels of IL-6, independent of age, sex, and depressive symptoms. These group differences were robust when controlling for neuroticism. Conversely, the groups had equivalent levels of CRP in all analyses. Results are indicative of anxiety-specific effects on inflammatory activity, and highlight a pathway by which anxiety may increase risk for inflammatory diseases.

Abstract
OBJECTIVE To examine the prospective association of depressive symptoms with circulating C-reactive protein (CRP) and to determine the direction of that association. METHODS Using data from 2,544 healthy participants in the Coronary Artery Risk Development in Young Adults study (ages, 33-45 years; 55% female; 42% black), we examined the prospective association of depressive symptoms, as measured by the Centers for Epidemiologic Studies Depression Scale, with circulating CRP 5 years later. RESULTS Depressive symptoms in the Coronary Artery Risk Development in Young Adults study Year 15 predicted CRP at Year 20, independent of demographic characteristics, biological and medical risk factors, health behaviors, and Year 15 CRP. This association, however, was conditional on race such that the increase in CRP with increasing depressive symptoms was present in blacks but not whites. In neither blacks nor whites did Year 15 CRP predict Year 20 depressive symptoms. Among black participants, when examined in separate analyses, higher scores on the depressed affect and somatic symptoms subscales of the Centers for Epidemiologic Studies Depression Scale and lower scores on the positive affect subscale were associated with greater Year 20 CRP. The interpersonal problems subscale was unrelated to CRP. When all four subscale scores were entered simultaneously in the same model, black participants' scores on the positive affect and somatic symptoms subscales emerged as independent predictors of Year 20 CRP, whereas the depressed affect and interpersonal problems subscales did not. CONCLUSIONS Depressive symptoms may be linked more closely to inflammation in blacks than in whites.
