RESUMEN

BACKGROUND: Some studies have demonstrated that subjects with chronic burnout showed cognitive impairments; however, cognitive performance in burnout has been under-investigated. Increasing evidence show that brain-derived neurotrophic factor (BDNF) plays a critical role in cognitive function. We hypothesized that decreased BDNF may be associated with cognitive impairments in burnout, which has not been investigated yet. The aim of the present study was to examine the association of BDNF with cognitive impairment in burnout. METHOD: Using a cross-sectional design, 712 healthy subjects were recruited from a general hospital and they were all measured with the Maslach Burnout Inventory (MBI). We assessed part of subjects on the repeatable battery for the assessment of neuropsychological status (RBANS) (n=192) and serum BDNF levels (n=127). RESULTS: 30.5% of the subjects had burnout. Compared to those non-burnout subjects, the burnout subjects were younger, had significant lower BDNF levels (p=0.003) and scored lower on immediate memory, RBANS total score and attention (all p<0.05). Interestingly, after the Bonferroni correction, there were negative correlations between BDNF and MBI total score or reduced professional accomplishment (PA). Moreover, BDNF was positively associated with immediate memory, attention and RBANS total score. Further multiple regression analysis showed that BDNF was an independent contributor to the RBANS total score and attention, and BDNF and MBI depersonalization (DP) were independent contributors to immediate memory. In addition, there was mediating effect of BDNF in the relation between burnout and cognitive impairments. CONCLUSIONS: Our results suggest that burnout is associated with significant cognitive impairments and decreased BDNF. Moreover, decreased BDNF is associated with cognitive impairments in burnout.

RESUMEN

Across the world, hospital nurses experience a high level of burnout. Exploring biochemical markers of burnout could help to understand physiological changes and may provide useful evidence for preventing burnout symptoms. The current study included 94 female nurses from one Chinese third-level hospital. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to investigate burnout symptoms: emotional exhaustion, cynicism, reduced professional efficacy, as well as the burnout average. The HPT axis was tested by checking blood levels of thyroid-stimulating hormone (TSH), thyroxin (T4) and triiodothyronine (T3). Nonparametric tests showed that no significant difference in biochemical markers was found between the burnout and non-burnout groups. Spearman correlation analysis found that biochemical markers had no significant association with burnout symptoms, except weakly negative associations between reduced professional efficacy and blood pressure and heart rate. These findings show a rather poor correlation of the HPT axis on burnout symptoms. Expanding the biochemical index of the HPT axis, comparing well-defined samples and using longitudinal studies are recommended for further studies.

RESUMEN

The regenerative hormone DHEA-S was measured in 122 patients with clinical burnout during their first year of treatment. Relations between change of DHEA-S levels and development in health were investigated. About half of the patients exhibited increased DHEA-S levels during the year, while the other half exhibited decreased levels. There was no difference in burnout symptoms or associated health status at baseline between subsequent DHEA-S increasing and DHEA-S decreasing groups. Greater reduction in the burnout symptoms was observed in patients in who DHEA-S levels increased during the year, than in the patients in who DHEA-S levels decreased. Relative change of DHEA-S and direction of the change during the year both predicted burnout symptoms at the end of the year. In addition, patients with increased DHEA-S levels had better self-rated health, vitality and well-being. Our data suggest that changes in DHEA-S are associated with prognosis for the outcome in burnout patients.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Work-related stress can lead to various health problems ranging from job-related exhaustion to psychiatric and somatic diseases. Biomarkers of job-related exhaustion could help to improve our understanding of the biological mechanisms and might be useful to guide prevention and treatment strategies. The present study included 12 male cases suffering from job-related exhaustion and 12 matched healthy controls. Severity of exhaustion was assessed with the Maslach Burnout Inventory (MBI) and the Shirom-Melamed Burnout Measure (SMBM). Whole genome expression profiles derived from whole blood cells (baseline and following glucocorticoid-receptor (GR) stimulation with 1.5mg dexamethasone p.o.) and corresponding plasma cortisol levels were analyzed. All cases participated in regular aerobic exercise for 12 consecutive weeks and were then re-assessed at follow-up for exhaustion symptoms as well as for cortisol levels and gene expression profiles. At baseline, we found increased basal cortisol levels and an enhanced suppression of plasma cortisol concentrations following dexamethasone in cases suffering from job-related exhaustion. Gene expression analysis revealed that 1.6-fold more transcripts were significantly regulated by dexamethasone in cases as compared to controls. At follow-up after 12 weeks of regular exercise training which was accompanied by significantly improved exhaustion severity scores, cortisol levels and gene expression profiles of cases normalized to the levels observed in controls. In conclusion, we detected GR-induced neuroendocrine and gene expression changes in cases suffering from job-related exhaustion which are in line with an increased sensitivity of GR function. This GR dysregulation normalized with symptom recovery.

RESUMEN

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.

RESUMEN

This study aimed to investigate the immediate effects of the secretory immunoglobulin A (sIgA), α-amylase activity and blood pressure levels after the application of a Reiki session in nurses with Burnout Syndrome. A randomized, double-blind, placebo-controlled, crossover design was conducted to compare the immediate effects of Reiki versus control intervention (Hand-off sham intervention) in nurses with Burnout Syndrome. Sample was composed of eighteen nurses (aged 34-56 years) with burnout syndrome. Participants were randomly assigned to receive either a Reiki treatment or a placebo (sham Reiki) treatment, according to the established order in two different days. The ANOVA showed a significant interaction time x intervention for diastolic blood pressure (F=4.92, P=0.04) and sIgA concentration (F=4.71, P=0.04). A Reiki session can produce an immediate and statistically significant improvement in sIgA concentration and diastolic blood pressure in nurses with Burnout Syndrome.

RESUMEN

Burnout is a work-related mental health impairment comprising three dimensions: emotional exhaustion, depersonalization, and reduced personal accomplishment. Reiki aims to help replenish and rebalance the body's energetic system, thus stimulating the healing process. The objective of this placebo-controlled, repeated measures, crossover, single-blind, randomized trial was to analyze the immediate effects of Reiki on heart rate variability (HRV), body temperature, and salivary flow rate and cortisol level in health care professionals with burnout syndrome (BS). Participants included 21 health care professionals with BS, who were asked to complete two visits to the laboratory with a 1-week interval between sessions. They were randomly assigned the order in which they would receive a Reiki session applied by an experienced therapist and a placebo treatment applied by a therapist with no knowledge of Reiki, who mimicked the Reiki treatment. Temperature, Holter ECG recordings (standard deviation of the normal-to-normal interval [SDNN], square root of mean squared differences of successive NN intervals [RMSSD], HRV index, low frequency component [LF], and high frequency component [HF]), salivary flow rate and cortisol levels were measured at baseline and postintervention by an assessor blinded to allocation group. SDNN and body temperature were significantly higher after the Reiki treatment than after the placebo. LF was significantly lower after the Reiki treatment. The decrease in the LF domain was associated with the increase in body temperature. These results suggest that Reiki has an effect on the parasympathetic nervous system when applied to health care professionals with BS.

RESUMEN

BACKGROUND: There are very few evaluations of the effectiveness of leadership development programs. The purpose of the study was to examine whether an art-based leadership program may have a more beneficial effect than a conventional one on leaders' and their corresponding subordinates' mental and biological stress. METHODS: Participating leaders were randomized to 2 year-long leadership programs, 1 art-based and 1 conventional, with follow-up of the leaders and their subordinates at 12 and 18 months. The art-based program built on an experimental theatre form, a collage of literary text and music, followed by writing and discussions focused on existential and ethical problems. RESULTS: After 18 months a pattern was clearly visible with advantage for the art-based group. In the art group (leaders and their subordinates together as well as for subordinates only) compared to the conventional group, there was a significant improvement of mental health, covert coping and performance-based self-esteem as well as significantly less winter/fall deterioration in the serum concentration of the regenerative/anabolic hormone dehydroepiandrosterone-sulfate. CONCLUSIONS: Our findings indicate a more beneficial long-term health effect of the art-based intervention compared to a conventional approach. Positive results for both standardized questionnaires and biological parameters strengthened the findings. The study provides a rationale for further evaluation of the effectiveness of this alternative educational approach.

RESUMEN

Chronic stress causes stress hormones to strain many biological systems in a process referred to as allostatic load (AL) that is measurable using an index of biomarkers. While the AL framework has been successfully applied in studies of workplace stress, few studies have investigated burnout, a debilitating condition sometimes characterized by blunted stress hormone levels. Using an AL index based on clinical norms, we hypothesized that higher AL indices would be associated with increased chronic stress, burnout symptoms, as well as hypoactive diurnal and reactive stress hormone levels. Fifteen neuroendocrine, immune, metabolic, and cardiovascular biomarkers were collected for 30 healthy participants from various professions and values were transformed into an AL index using clinical norms. Stress reactivity was assessed for salivary cortisol and α-amylase levels in response to the Trier Social Stress Test. Diurnal cortisol was measured at five time points (awakening, 30 min after awakening, 14:00 h, 16:00 h, and before bedtime) over two working days. We also administered questionnaires of chronic stress, burnout, and depression. Our results demonstrate that increased AL is associated with increased chronic stress, burnout symptoms, but not depressive symptoms. The High AL group demonstrated lower morning and stress reactive cortisol levels in comparison to the Low AL group, but no significant effects were detected for salivary α-amylase. These findings provide preliminary support for the utility of a new clinical AL index that is sensitive to physiological recalibrations intermittently observed in burnout research.

RESUMEN

The burnout syndrome is an important psychosocial risk in the job context, especially in professions with a strong social interaction, as in the case of teaching. High levels of burnout have been related to negative psychological indicators and hormonal alterations. This study compares job satisfaction and the cortisol awakening response (CAR) in teachers scoring high (HB) and low (LB) on burnout. HB teachers showed lower job satisfaction and no significant differences in the CAR when compared with the LB group. The results of the study suggest a general dissatisfaction with work along with a different functioning of the hypothalamo-pituitary-adrenocortical axis in HB teachers. Although non significantly, they showed a lower magnitude of the CAR than LB teachers. When considering the whole sample, emotional exhaustion and depersonalization correlated negatively and personal accomplishment positively with each subscale of the job satisfaction questionnaire whereas cortisol levels or CAR did not correlate significantly with both burnout subscales and job satisfaction. These results should be taken into account when working to prevent burnout in teachers, as the modified parameters could be considered indicators of the onset or development of the syndrome.

RESUMEN

OBJECTIVE: To evaluate the effects of a stress management intervention among 24 female patients on sick leave due to work-related psychological complaints. METHODS: The study design was quasi-experimental. All participants received a standard individual treatment for stress at a company healthcare unit. Half of the sample was also enrolled in a group intervention aimed at coping with psychological/somatic symptoms of stress. Data were collected before and after treatment and at 6- and 12-month follow-ups, through questionnaires and blood sampling. Rates of return to work were assessed for up to 5 years. RESULTS: Levels of depression decreased in both conditions and these improvements were maintained at follow-up. The experimental condition was superior in alleviating burnout, as measured with the Karolinska Exhaustion Scale. Paradoxically, these improvements were accompanied by significant increases in levels of glycated haemoglobin in both groups. At 5-year follow-up 40% of participants in both conditions had returned to work. CONCLUSION: The stress management intervention seems to have beneficial effects on self-rated symptoms, but is comparable to treatment as usual with respect to rates of return to work. More studies are needed to investigate the impact of this intervention on physiological parameters.

RESUMEN

OBJECTIVE: The burnout syndrome has been associated with an increased risk of cardiovascular disease. The physiological mechanisms potentially involved in this link are underexplored. Knowing that a chronic low-grade systemic inflammatory state contributes to atherosclerosis, we investigated circulating cytokine levels in relation to burnout symptoms. METHODS: We studied 167 schoolteachers (median, 48 years; range, 23-63 years; 67% women) who completed the Maslach Burnout Inventory with its three subscales emotional exhaustion (EE), lack of accomplishment (LA), and depersonalization (DP). Levels of the proinflammatory cytokine tumor necrosis factor (TNF)-alpha and of the anti-inflammatory cytokines interleukin (IL)-4 and IL-10 were determined in fasting morning plasma samples. The TNF-alpha/IL-4 ratio and the TNF-alpha/IL-10 ratio were computed as two indices of increased inflammatory activity. Analyses were adjusted for demographic factors, medication, lifestyle factors (including sleep quality), metabolic factors, and symptoms of depression and anxiety. RESULTS: Higher levels of total burnout symptoms aggregating the EE, LA, and DP subscales independently predicted higher TNF-alpha levels (DeltaR(2)=.024, P=.046), lower IL-4 levels (DeltaR(2)=.021, P=.061), and a higher TNF-alpha/IL-4 ratio (DeltaR(2)=.040, P=.008). Higher levels of LA predicted decreased IL-4 levels (DeltaR(2)=.041, P=.008) and a higher TNF-alpha/IL-4 ratio (DeltaR(2)=.041, P=.007). The categorical dimensions of the various burnout scales (e.g., burnout yes vs. no) showed no independent relationship with any cytokine measure. CONCLUSION: Burnout was associated with increased systemic inflammation along a continuum of symptom severity rather than categorically. Given that low-grade systemic inflammation promotes atherosclerosis, our findings may provide one explanation for the increased cardiovascular risk previously observed in burned-out individuals.

RESUMEN

BACKGROUND: Burnout has a negative impact on physical health, but the mechanisms underlying this relation remain unclear. To elucidate these mechanisms, possible mediating physiological systems or risk factors for adverse health in burned-out employees should be investigated. GOAL: The aim of the present study among 290 Dutch managers was to explore whether allostatic load mediates the relationship between burnout and physical health. METHOD: Burned-out managers, as identified with the Maslach Burnout Inventory General Survey (MBI-GS), were compared with a healthy control group with regard to their allostatic load. The allostatic load index included eight parameters: Body-mass index (BMI), systolic and diastolic blood pressure (SBP and DBP), C-reactive protein (CRP), high-density lipoprotein (HDL), cholesterol, glycosylated hemoglobin (HbA1C) and glucose. RESULTS: Contrary to expectations, burned-out managers did not differ from healthy managers with regard to their scores on the allostatic load index. An additional analysis, using groups of managers in the extreme deciles of exhaustion (the core symptom of burnout), did also not reveal differences in allostatic load. CONCLUSION: Burnout seems not to be associated with this proxy measure of allostatic load. The mediating physiological mechanisms between burnout and objective physical health remain to be elucidated.

RESUMEN

BACKGROUND: Plasma prolactin levels are sensitive to dopamine and serotonin function, and fatigue. Low cortisol, dopamine and/or serotonin may be involved in burnout and detachment. METHODS: In this double-blind within-subject study, we treated 9 female burnout subjects and 9 controls with 35 mg cortisol and placebo orally. We measured state affect and plasma prolactin, oxytocin, cortisol and adrenocorticotropic hormone levels, and administered an attachment questionnaire. RESULTS: The burnout subjects displayed an extreme distribution of basal prolactin levels, displaying higher or lower levels compared to the controls. The low prolactin burnouts had profoundly low attachment scores and tended to have low oxytocin levels. The high prolactin burnout subjects tended to show cortisol-induced decreased prolactin and fatigue, and increased vigor. CONCLUSION: Results are consistent with the hypothesis that burnout subjects are either characterized by low serotonergic function or by low dopaminergic function, and that the latter group benefits from cortisol replacement. These preliminary results suggest that differentiating between two syndromes may resolve inconsistencies in research on burnout, and be necessary for selecting the right treatment strategy.

RESUMEN

OBJECTIVE: To explore the relationship between occupational stress and blood glucose, Blood lipid and blood pressure. METHODS: 108 video display terminals(VDT) operators who had the working experience were recruited to the study. The occupational stress indicator (OSI), the lever of blood glucose, cholesterol, triglyceride, lipoprotein of high density and lipoprotein of low density in serum were measured by using GOD-PAP, CHOD-PAP, GPO-PAP and PVS. The subjects were classified into three groups according to the score of occupational stress. RESULTS: The contents of blood glucose of low, middle and high level of stress groups were (3.39 +/- 1.24), (3.59 +/- 1.26), (2.54 +/- 0.94) mmol/L respectively (F = 7.324, P < 0.01), and with the increase of level of stress, the content of blood glucose decreased significantly (r = -0.376, P < 0.01). CONCLUSION: The level of blood glucose of VDT operators is affected by occupational stress, among video display terminals and it can be used as the index for estimating occupational stress.

RESUMEN

The authors' goal was to document baseline pituitary-adrenal hormonal and related metabolic variables in 16 female patients with burnout. Then, following stress management intervention, to compare the changes with an equal number of untreated control subjects. At monthly intervals for 4 mo, 24-h urine samples were obtained for determination of free cortisol excretion. In addition, fasting blood samples were analyzed for levels of cortisol, dehydroepiandrosterone sulfate (DHEAS), ACTH, aldosterone, and catecholamines. Other biochemical measurements included growth hormone, prolactin, insulin, glucose, and lipid components. The Maslach Burnout Inventory, General Health Questionnaire- 28, and Zung depression rating scale were completed on each consecutive visit. The most striking finding was the reduction of urine free-cortisol excretion in the patients compared with controls. Initial urinary free cortisol was significantly lower in the patients (mean +/- SEM = 47.2 +/- 11.0 vs 79.0 +/- 6.8 nmol/L, p = 0.02) and remained significantly reduced at 4 mo (mean +/- SEM = 44.0 +/- 6.1 vs 91.1 +/- 8.8 nmol/L, p = 0.0001). There were no significant changes in the other hormonal and biochemical data. We conclude that there is functional hypocortisolism in burnout, which is not immediately restored on stress management intervention despite clinical and psychological improvement.
