The Outcome of Psychiatric Rehabilitation Treatment Depends on Affective State at the Time of Admission.

BACKGROUND: In Austria, new approaches of rehabilitation programs focus on the prevention of mental illness and offer treatment not only for acute psychiatric patients, but also for those who are at risk of developing a mental disorder or have recovered from one.The aim of this study was to determine the effects of a psychiatric rehabilitation program on individuals with different mood states. SUBJECTS AND METHODS: 600 patients with a history of affective disorder were tested at the time of admission to an Austrian inpatient psychiatric rehabilitation center. Data of extreme groups - patients who were depressed (n=59; BDI-II<9 and HAMD<8) or euthymic (n=59; BDI<18 and HAMD>19) at the time of therapy start - were analyzed. The participants completed the Maslach Burnout Inventory - General Survey, the Symptom Checklist - Revised and the Stress Coping Questionnaire at the beginning and the end of the 6-weeks rehabilitation program. RESULTS: After 6 weeks, both groups showed significantly less psychiatric symptoms (BDI-II, HAMD, SCL-90, and negative coping strategies (SVF). Importantly, work-related stress symptoms ("burnout" symptoms) improved significantly in the euthymic group. CONCLUSIONS: Euthymic patients seem to be able to focus on work-related stress symptoms including reduced emotional exhaustion through treatment, while currently depressed patients primarily benefit by an improvement in general psychiatric symptomatology. The results indicate the crucial role of mood state validated with standardized psychological questionnaires BDI-II and HAMD at time of admission to such programs. These findings could have implications on treatment decisions for psychiatric patients and assist in making a forecast concerning ability to recover and treatment prognosis.

The Impact of Probiotic Supplements on Cognitive Parameters in Euthymic Individuals with Bipolar Disorder: A Pilot Study.

INTRODUCTION: Cognitive dysfunction is prevalent in depressive as well as manic episodes in individuals with Bipolar Disorder (BD). Even more, after symptom remission, many individuals with BD experience persisting cognitive impairment also in euthymic periods, leading to high illness burden and low quality of life. According to a recent research in animals and healthy humans, microbiota may influence cognitive processes via the brain-gut axis. A strategy to examine the role of the microbiota in different diseases is the intake of supplements that modulate the gut microbiome. The aim of this pilot study was to analyze the impact of probiotic supplements on cognitive parameters in a cohort of euthymic individuals with BD, receiving daily probiotic treatment over a time period of 3 months. METHODS: A total of 20 euthymic individuals with BD received probiotic supplement over a time period of 3 months and completed a cognitive test battery at 3 time points (t1 at time of inclusion, t2 after one month and t3 after 3 months of probiotic intake). RESULTS: We found a significant improvement of performance concerning attention and psychomotor processing speed measured with the Digit Symbol Test after one (t2) as well as after 3 months (t3) of treatment (F = 8.60; η2 = 0.49, p < 0.01). Furthermore, executive function measured with the TMT-B, increased significantly over 3 months (F = 3.68; η2 = 0.29, p < 0.05). CONCLUSION: The results confirm the hypotheses that probiotic supplement might help stable individuals with BD to improve the cognitive function, which in turn might lead to better psychosocial, occupational, work and financial functioning. Nevertheless, the idea of this potential new treatment is challenging because of the variety of the human's gut microbiota.

Sex Specific Changes in Tryptophan Breakdown Over a 6 Week Treatment Period.

Introduction: Despite the knowledge of sex differences concerning neurobiological parameters as well as clinical course of illness in individuals with mood disorders, the literature concerning tryptophan (Trp) breakdown, specific for women and men, is sparse to date. The current study aimed to evaluate sex differences in Trp, kynurenine (Kyn) and Kyn/Trp concentrations in general, as well as differences in changes of those concentrations over the course of a 6-week rehabilitation program in individuals with life-time unipolar affective disorder. For this purpose changes in Trp and Kyn as well as the Kyn/Trp concentrations between the time of admission (t1) and discharge (t2) were analyzed in dependence of sex. Furthermore, correlations between Trp and Kyn levels and clinical parameters were performed separately for male and female participants. Material and Methods: Results: For the current analysis 426 individuals with lifetime affective disorder completing a 6-week rehabilitation program were included. In both sexes, psychiatric symptoms decreased significantly over time. There was a significant difference between women (n = 242) and men (n = 184) regarding the changes in Trp, Kyn, and Kyn/Trp over time even if controlled for relevant covariates [multivariate: F (3, 380) = 2.663, η2 = 0.021, p = 0.048]. Kyn as well as Kyn/Trp concentrations increased significantly in men over time (Kyn F = 4.809, η2 = 0.012, p = 0.029; Kyn/Trp F = 7.923, η2 = 0.020, p = 0.005). Results remained the same when controlled for psychiatric symptoms. Discussion: The main finding of the present study is the significant difference between women and men regarding the change in Trp, Kyn, and Kyn/Trp over a 6-week psychiatric treatment period, while the depression severity scores as well as general psychiatric symptoms decreased. Sex specific changes in Trp-Kyn pathways have only been explored to a very small extent to date in the literature but are of high clinical relevance in the context of personalized medicine.

Physical health in individuals with psychiatric disorders in Austria.

INTRODUCTION: The association between severe psychiatric disorders and metabolic syndrome is well documented and goes along with a reduced life expectancy. The prevalence of medical comorbidities in individuals suffering from psychiatric disorders in Austria has not yet been examined; aim of this study was to analyze the prevalence of comorbid somatic disorder in individuals diagnosed with psychiatric disorders in Austria. METHODS: Patients (n = 600) with a life-time diagnosis of mood and anxiety disorders undergoing a six-week course of intensive treatment in a psychiatric rehabilitation center were recruited. Prevalent somatic and psychological conditions, anamnestic data, medical history, blood samples, clinical and psychological tests as well as medication were examined to determine somatic and psychiatric diagnoses. RESULTS: Metabolic disorders were highly prevalent especially in individuals diagnosed with affective disorders, respectively in bipolar disorder. Furthermore, obesity and thyroid dysfunction were found in about 40% of individuals diagnosed with bipolar disorder in the present study. Significant gender differences were found in CVD and hypertension with higher prevalence in men, while thyroid dysfunction occurred more often in women also compared to the general female population. CONCLUSIONS: Characterizing somatic comorbidity in individuals with psychiatric disorders can stimulate research to better understand possible shared etiologic factors and has public health implications for improving models of care. This could have a positive effect on the course of mental disorders, and additionally improve social integration and life expectancy. Knowledge about sex differences should be used to further improve individualized treatment of individuals with psychiatric disorders.

Psychopathic personality factor "Fearless dominance" is related to low self-reported stress-levels, fewer psychiatric symptoms, and more adaptive stress coping in psychiatric disorders.

The aim of this cross-sectional study was to test the idea that the psychopathic trait "Fearless dominance" (FD) may be associated with reduced psychological stress symptoms and better stress coping strategies in psychiatric patients, whereas the factor "Self-centered impulsivity" (SCI) may be associated with more stress and maladaptive stress coping. The investigation included 626 individuals with psychiatric disorders treated in a psychiatric rehabilitation program. The participants were tested with the Psychopathic Personality Inventory Revised (PPI-R) and completed several clinical scales measuring stress experience and stress coping (Symptom-Checklist Revised, Trier Inventory for Chronic Stress, The Stress Coping Style Questionnaire 78). Consistent with the hypothesis, structural equation modeling results showed that self-reported stress levels and adaptive stress coping strategies might be explained by psychopathic FD traits in the psychiatric sample. Supplemental subscale analyses showed that especially the PPI-R scales Stress Immunity and Social Influence were positively related to adaptive stress coping. The second model of SCI did not fit our data well. In conclusion, individuals with psychopathic FD traits may experience less stress symptoms during residential care. Well-designed prospective trials may ultimately answer the question whether psychopathic traits could be viewed as serving a buffer function in the development of depression.

[Cognitive impairments accompanying the burnout syndrome - a review]. / Kognitive Defizite beim Burnout-Syndrom ­ Ein Überblick.

BACKGROUND: The rising prevalence of the burnout syndrome has increasingly moved it into the focus of scientific interest. In addition to emotional exhaustion and depersonalization, particularly reduced personal accomplishment has strong societal and economic effects. In recent years reduced personal accomplishment has increasingly been linked to cognitive impairment. However, up to now only a few studies have objectively assessed cognitive deficits in burnout patients. This article gives an overview of 16 studies which examined cognitive abilities in burnout patients. The findings are partly contradictory, probably due to methodical differences. Consensus has emerged concerning impairments of executive functions, i.a. vigilance, and memory updating and monitoring. Multifactorial causation may underlie the cognitive impairments. OUTLOOK: Targeted longitudinal studies are necessary in order to identify the affected cognitive functions and be able to make causal inferences on links between the burnout syndrome and specific cognitive impairments.
