RESUMO

INTRODUCTION: Germany is one of the few countries with a medical specialty of psychosomatic medicine and psychotherapy and many treatment resources of this kind. OBJECTIVE: This observational study describes the psychosomatic treatment programs as well as a large sample of day-hospital and inpatients in great detail using structured diagnostic interviews. METHODS: Mental disorders were diagnosed according to ICD-10 and DSM-IV by means of Mini-DIPS and SCID-II. In addition to the case records, a modified version of the CSSRI was employed to collect demographic data and service use. The PHQ-D was used to assess depression, anxiety, and somatization. RESULTS: 2,094 patients from 19 departments participated in the study after giving informed consent. The sample consisted of a high proportion of "complex patients" with high comorbidity of mental and somatic diseases, severe psychopathology, and considerable social and occupational dysfunction including more than 50 days of sick leave per year in half of the sample. The most frequent diagnoses were depression, somatoform and anxiety disorders, eating disorders, personality disorders, and somato-psychic conditions. CONCLUSIONS: Inpatient and day-hospital treatment in German university departments of psychosomatic medicine and psychotherapy is an intensive multimodal treatment for complex patients with high comorbidity and social as well as occupational dysfunction.

RESUMO

Chronic heart failure is associated with reduced myocardial ß-adrenergic receptor expression and mitochondrial function. Since these data coincide with increased plasma catecholamine levels, we investigated the relation between myocardial ß-receptor expression and mitochondrial respiratory activity under conditions of physiological catecholamine concentrations. This post hoc analysis used material of a prospective randomized, controlled study on 12 sexually mature (age 20-24 weeks) Early Life Stress or control pigs (weaning at day 21 and 28-35 after birth, respectively) of either sex. Measurements in anesthetized, mechanically ventilated, and instrumented animals comprised serum catecholamine (liquid-chromatography/tandem-mass-spectrometry) and 8-isoprostane levels, whole blood superoxide anion concentrations (electron spin resonance), oxidative DNA strand breaks (tail moment in the "comet assay"), post mortem cardiac tissue mitochondrial respiration, and immunohistochemistry (ß2-adrenoreceptor, mitochondrial respiration complex, and nitrotyrosine expression). Catecholamine concentrations were inversely related to myocardial mitochondrial respiratory activity and ß2-adrenoceptor expression, whereas there was no relation to mitochondrial respiratory complex expression. Except for a significant, direct, non-linear relation between DNA damage and noradrenaline levels, catecholamine concentrations were unrelated to markers of oxidative stress. The present study suggests that physiological variations of the plasma catecholamine concentrations, e.g., due to physical and/or psychological stress, may affect cardiac ß2-adrenoceptor expression and mitochondrial respiration.

RESUMO

Flow experience, a feeling of being absorbed in an activity without reflection and with maximum depth, has positive effects on psychological and physical well-being, performance, and life satisfaction. Little research has been done on flow experience in old age, and there are no studies on geriatric patients. In the present study, elderly patients (mean age:81.2, SD=5.9) of a day hospital were examined with regard to their flow experience using the flow short scale. In addition to age and gender effects, flow was assessed during two different activities ( physical activity vs. memory training). Furthermore, the role of individual activity and group dynamics as well as correlations between flow and therapy success were examined in detail. The results show that flow experience is possible even in old age. Depressed patients experienced as much flow as non-depressed patients; cognitively impaired patients, on the other hand, experienced less flow than patients without cognitive deficits, and chronic pain patients even reported more flow experiences during exercise programs than patients without pain. A high level of self-activity had an overall positive effect on the flow experience. The therapy outcome could not be influenced by flow. Flow experience in old age should be given more attention, especially in physical activity therapy for pain patients; further correlations, especially with regard to depression, remain to be investigated.

RESUMO

OBJECTIVE: Since 1996, older patients have been treated in the Nuremberg Geriatric Day Hospital. The geriatric depression scale (GDS) is an obligatory part of the geriatric assessment at admission but its use in the clinical setting has revealed some problems. The aim of the study was to compare the GDS with the depression in old age scale (DIA-S) in terms of applicability and psychometric characteristics. METHODS: As gold standard a semi-structured interview was used to record the depression criteria according to Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Using a sample of 375 patients, sensitivity and specificity as well as positive and negative predictive values were calculated for both screening tests. RESULTS: No clear superiority of any screening method could be proven. The sensitivity of the DIA­S in the overall sample was higher than that of the GDS, but the specificity was much lower. In terms of predictive values, there were slight advantages for the GDS. In the sub-samples, poorer values were found in both scales for cognitively impaired or dementia patients with slightly better values for GDS. CONCLUSION: The DIA­S can be used very easily in everyday clinical practice, but no advantages of this method compared to GDS could be demonstrated.

RESUMO

Urbanization is on the rise, and environments offering a narrow range of microbial exposures are linked to an increased prevalence of both physical and mental disorders. Human and animal studies suggest that an overreactive immune system not only accompanies stress-associated disorders but might even be causally involved in their pathogenesis. Here, we show in young [mean age, years (SD): rural, 25.1 (0.78); urban, 24.5 (0.88)] healthy human volunteers that urban upbringing in the absence of pets (n = 20), relative to rural upbringing in the presence of farm animals (n = 20), was associated with a more pronounced increase in the number of peripheral blood mononuclear cells (PBMCs) and plasma interleukin 6 (IL-6) concentrations following acute psychosocial stress induced by the Trier social stress test (TSST). Moreover, ex vivo-cultured PBMCs from urban participants raised in the absence of animals secreted more IL-6 in response to the T cell-specific mitogen Con A. In turn, antiinflammatory IL-10 secretion was suppressed following TSST in urban participants raised in the absence of animals, suggesting immunoregulatory deficits, relative to rural participants raised in the presence of animals. Questionnaires, plasma cortisol, and salivary α-amylase, however, indicated the experimental protocol was more stressful and anxiogenic for rural participants raised in the presence of animals. Together, our findings support the hypothesis that urban vs. rural upbringing in the absence or presence of animals, respectively, increases vulnerability to stress-associated physical and mental disorders by compromising adequate resolution of systemic immune activation following social stress and, in turn, aggravating stress-associated systemic immune activation.

RESUMO

This paper explored the potential mediating role of hydrogen sulfide (H2S) and the oxytocin (OT) systems in hemorrhagic shock (HS) and/or traumatic brain injury (TBI). Morbidity and mortality after trauma mainly depend on the presence of HS and/or TBI. Rapid "repayment of the O2 debt" and prevention of brain tissue hypoxia are cornerstones of the management of both HS and TBI. Restoring tissue perfusion, however, generates an ischemia/reperfusion (I/R) injury due to the formation of reactive oxygen (ROS) and nitrogen (RNS) species. Moreover, pre-existing-medical-conditions (PEMC's) can aggravate the occurrence and severity of complications after trauma. In addition to the "classic" chronic diseases (of cardiovascular or metabolic origin), there is growing awareness of psychological PEMC's, e.g., early life stress (ELS) increases the predisposition to develop post-traumatic-stress-disorder (PTSD) and trauma patients with TBI show a significantly higher incidence of PTSD than patients without TBI. In fact, ELS is known to contribute to the developmental origins of cardiovascular disease. The neurotransmitter H2S is not only essential for the neuroendocrine stress response, but is also a promising therapeutic target in the prevention of chronic diseases induced by ELS. The neuroendocrine hormone OT has fundamental importance for brain development and social behavior, and, thus, is implicated in resilience or vulnerability to traumatic events. OT and H2S have been shown to interact in physical and psychological trauma and could, thus, be therapeutic targets to mitigate the acute post-traumatic effects of chronic PEMC's. OT and H2S both share anti-inflammatory, anti-oxidant, and vasoactive properties; through the reperfusion injury salvage kinase (RISK) pathway, where their signaling mechanisms converge, they act via the regulation of nitric oxide (NO).

RESUMO

BACKGROUND AND OBJECTIVE: The aim of the study was to evaluate a specific treatment concept for patients suffering from dementia in a geriatric day clinic with respect to improvement of dementia-related behavioral abnormalities and effects on distress of the caring relatives. MATERIAL AND METHODS: Designed as a naturalistic study with a sample of 34 dementia patients (average age 83 years, 62% female, 82% mild dementia, 18% moderate dementia) surveyed at three time points, the dementia-related behavioral symptoms and the relatives' distress were measured using the neuropsychiatric inventory. A waiting time before treatment was implemented as a control condition. RESULTS: Compared with waiting time, a significant improvement of dementia-related behavioral abnormalities was found after treatment, especially in patients suffering from moderate dementia. The distress of caring relatives was clearly reduced. CONCLUSION: The interprofessional treatment of patients with dementia using a specific program in a geriatric day clinic leads to a clear improvement in behavioral symptoms and positively influences the distress of caring relatives.

RESUMO

People with mental illness can internalize public prejudice and negative emotional reactions to their group, leading to self-contempt. This study examined self-contempt related to having a mental illness as predictor of suicidality among 77 people with mental illness in Southern Germany. Self-contempt, depressive symptoms, hopelessness, and suicidality were assessed at baseline; suicidality was measured again 3 months later. High self-contempt at baseline predicted increased suicidality at follow-up, adjusting for baseline suicidality, symptoms, diagnosis, age, sex, and hopelessness. These results suggest that self-contempt may be a risk factor for suicidality and call for specific interventions targeting self-stigma and its emotional consequences.

RESUMO

Experiencing maltreatment during childhood can have long-lasting consequences for both mental and physical health. Immune cell telomere length (TL) shortening might be one link between child maltreatment (CM) experiences and adverse health outcomes later in life. While the stress hormone cortisol has been associated with TL attrition, the attachment-related hormone oxytocin may promote resilience. In 15 mothers with and 15 age- and body mass index-matched mothers without CM, we assessed TL in peripheral blood mononuclear cells and selected immune cell subsets (monocytes, naive, and memory cytotoxic T cells) by quantitative fluorescence in situ hybridization, as well as peripheral cortisol and oxytocin levels. Memory cytotoxic T cells showed significantly shorter TL in association with CM, whereas TL in monocytes and naive cytotoxic T cells did not significantly differ between the two groups. Across both groups, cortisol was negatively associated with TL, while oxytocin was positively associated with TL in memory cytotoxic T cells. These results indicate that long-lived memory cytotoxic T cells are most affected by the increased biological stress state associated with CM. Keeping in mind the correlational and preliminary nature of the results, the data suggest that cortisol may have a damaging and oxytocin a protective function on TL.

RESUMO

BACKGROUND: Gender medicine has gained importance over the past 20 years. Nevertheless, the scientific findings concerning gender- and sex-specific patient care have not been sufficiently integrated into the education of physicians. It was therefore our aim, against initial resistance in our school, to integrate clinically relevant aspects of gender medicine into the existing medical curriculum. This paper describes the implementation process of a lecture-based interdisciplinary, longitudinal, basic gender curriculum and evaluates students' attitudes in relation to sex and semester level. METHODS: The curriculum encompasses 15 lecture sessions scheduled in years 1 through 5 of the medical curriculum at Ulm University, Germany. Prospectively gathered evaluation data of two cross-sectional analyses of this basic curriculum in the first and fifth semesters are analyzed by sex. RESULTS: More than 80% of the students have registered for this new curriculum. Evaluation data show a predominantly positive (75.5%) student response; however, only about half of those surveyed indicated that they had learned new material or judged the content on gender to be relevant to their practice of medicine. Students at a more advanced semester level (88.2% vs. 55.2%) and male participants more than female participants (36.7% vs. 62.4%) showed lower acceptance. DISCUSSION: It was possible to integrate gender issues into the existing medical student curriculum. Despite the overall positive rating, our evaluation data identified the aspects of rejection and resistance in some students, particularly male and more advanced students. Further studies on the development of student attitudes toward gender issues are needed.

RESUMO

Flow refers to a positive, activity-associated, subjective experience under conditions of a perceived fit between skills and task demands. Using functional magnetic resonance perfusion imaging, we investigated the neural correlates of flow in a sample of 27 human subjects. Experimentally, in the flow condition participants worked on mental arithmetic tasks at challenging task difficulty which was automatically and continuously adjusted to individuals' skill level. Experimental settings of "boredom" and "overload" served as comparison conditions. The experience of flow was associated with relative increases in neural activity in the left anterior inferior frontal gyrus (IFG) and the left putamen. Relative decreases in neural activity were observed in the medial prefrontal cortex (MPFC) and the amygdala (AMY). Subjective ratings of the flow experience were significantly associated with changes in neural activity in the IFG, AMY, and, with trend towards significance, in the MPFC. We conclude that neural activity changes in these brain regions reflect psychological processes that map on the characteristic features of flow: coding of increased outcome probability (putamen), deeper sense of cognitive control (IFG), decreased self-referential processing (MPFC), and decreased negative arousal (AMY).

RESUMO

Despite recent advances in understanding the relevance of cell adhesion-related signaling in the pathogenesis of ischemic cardiomyopathy (ICM) in animal models, substantial questions remain unanswered in the human setting. We have previously shown that the neural cell adhesion molecule CD56 [neural cell adhesion molecule (NCAM1)] is specifically overexpressed in ICM; it was the aim of the current study to further elucidate the role of CD56 in the pathogenesis of human ICM. We used quantitative real-time PCR and IHC in human ICM and a rat model of coronary obstruction to demonstrate that CD56(140kD), the only extraneuronally expressed NCAM1 isoform with a cytoplasmic protein domain capable of inducing intracellular signaling, is the only up-regulated CD56 isoform in failing cardiomyocytes in human ICM in vivo. In subsequent analyses of the cellular effects of CD56(140kD) overexpression in the development of ICM using differential whole transcriptome expression analyses and functional in vitro cardiomyocyte cell culture assays, we further show that the up-regulation of CD56(140kD) is associated with profound gene expression changes, increased apoptosis, and reduced Ca(2+) signaling in failing human cardiomyocytes. Because apoptosis and Ca(2+)-related sarcomeric dysfunction are molecular hallmarks of ICM in humans, our results provide strong evidence that CD56(140kD) up-regulation plays a pivotal role in the pathogenesis of ICM and may be a target for future immunotherapeutic strategies in the treatment of this common and often fatal disease.

RESUMO

Past findings have suggested that there is a link between attachment representations and reactions towards stress (subjective and physiological). The aim of this study was to examine the mediating effect of perceived stress on the association between attachment representation and physiological changes, specifically heart rate. As part of a long-term study investigating the transgenerational transmission of childhood maltreatment, n = 163 mothers participated in multiple assessments. The Adult Attachment Projective Picture System (AAP) was used to measure maternal attachment representation, categorizing individuals as securely or insecurely attached. Perceived daily stress was assessed using the Perceived Stress Scale 14 (PSS-14), and maternal baseline heart rate (HR) was measured via electrocardiography during a laboratory visit. The results revealed that the representation of secure attachment had a significant reducing effect on both the mother's perceived daily stress and heart rate. Furthermore, the association between secure attachment representation and heart rate was mediated by perceived stress. This study emphasizes the role of attachment representation in maternal well-being, highlighting its impact on stress and physiological responses.

RESUMO

Introduction: Circulating levels of the antiangiogenic protein vasoinhibin, a fragment of prolactin, are of interest in vasoproliferative retinopathies, preeclampsia, and peripartum cardiomyopathy; however, it is difficult to determine the circulating levels of vasoinhibin due to the lack of quantitative assays. Methods: This study used human serum samples to assess the concentration and bioactivity of vasoinhibin using a novel enzyme-linked immunosorbent assay (ELISA) for human vasoinhibin, which employs an anti-vasoinhibin monoclonal antibody, a human umbilical vein endothelial cell (HUVEC) proliferation assay, and a chick chorioallantoic membrane (CAM) angiogenesis assay. Results: Serum samples from 17 pregnant women without (one group) and with preeclampsia and pregnancy induced hypertension (another group) demonstrated endogenous vasoinhibin concentrations in the range of 5-340 ng/ml. Immunoactive vasoinhibin levels were significantly higher in preeclampsia serum compared to healthy pregnancy serum (mean 63.09 ± 22.15 SD vs. 19.67 ± 13.34 ng/ml, p = 0.0003), as was the bioactive vasoinhibin level as determined by the HUVEC proliferation assay (56.12 ± 19.83 vs. 13.38 ± 4.88 ng/ml, p < 0.0001). There was a correlation between the concentration of vasoinhibin measured by ELISA and the HUVEC proliferation assay (Pearson r = 0.95, p < 0.0001). Healthy serum demonstrated a proangiogenic effect in the CAM assay (p < 0.05, compared to control), while serum from preeclamptic patients demonstrated an antiangiogenic effect (p < 0.05 vs. control), as did recombinant human vasoinhibin and a synthetic circular retro-inverse vasoinhibin analogue (CRIVi45-51). The antiangiogenic effects in the CAM assay and the inhibition of HUVEC proliferation were abolished by addition of the ELISA anti-vasoinhibin monoclonal antibody, but not by mouse IgG. Discussion: These results demonstrate the first quantitation of endogenous vasoinhibin in human sera and the elevation of it levels and antiangiogenic activity in sera from women with preeclampsia. The development and implementation of a quantitative assay for vasoinhibin overcomes a long-standing barrier and suggests the thorough clinical verification of vasoinhibin as a relevant biomarker.

RESUMO

Collagen breakdown and de novo synthesis are important processes during early wound healing after myocardial infarction (MI). We tested the hypothesis that collagen I, the main constituent of the extracellular matrix, affects wound healing after MI. The osteogenesis imperfecta mouse (OIM), lacking procollagen-α2(I) expression, represents a model of the type III form of the disease in humans. Homozygous (OIM/OIM), heterozygous (OIM/WT), and wild-type (WT/WT) mice were subjected to a permanent myocardial infarction protocol or sham surgery. Baseline functional and geometrical parameters determined by echocardiography did not differ between genotypes. After MI but not after sham surgery, OIM/OIM animals exhibited significantly increased mortality, due to early ventricular rupture between day 3 and 7. Echocardiography at day 1 demonstrated increased left ventricular dilation in OIM/OIM animals. Less collagen I mRNA within the infarct area was found in OIM/OIM animals. At 2 days after MI, MMP-9 expression in the infarct border zone was higher in OIM/OIM than in WT/WT animals. Increased granulocyte infiltration into the infarct border zone occurred in OIM/OIM animals. Neither granulocyte depletion nor MMP inhibition reduced mortality in OIM/OIM animals. In this murine model, deficiency of collagen I leads to a myocardial wound-healing defect. Both structural alterations within pre-existing collagen matrix and impaired collagen de novo expression contribute to a high rate of early myocardial rupture after MI.

RESUMO

Background: Early Life Stress (ELS) may exert long-lasting biological effects, e.g., on PBMC energy metabolism and mitochondrial respiration. Data on its effect on brain tissue mitochondrial respiration is scarce, and it is unclear whether blood cell mitochondrial activity mirrors that of brain tissue. This study investigated blood immune cell and brain tissue mitochondrial respiratory activity in a porcine ELS model. Methods: This prospective randomized, controlled, animal investigation comprised 12 German Large White swine of either sex, which were weaned at PND (postnatal day) 28-35 (control) or PND21 (ELS). At 20-24 weeks, animals were anesthetized, mechanically ventilated and surgically instrumented. We determined serum hormone, cytokine, and "brain injury marker" levels, superoxide anion (O2 •¯) formation and mitochondrial respiration in isolated immune cells and immediate post mortem frontal cortex brain tissue. Results: ELS animals presented with higher glucose levels, lower mean arterial pressure. Most determined serum factors did not differ. In male controls, TNFα and IL-10 levels were both higher than in female controls as well as, no matter the gender in ELS animals. MAP-2, GFAP, and NSE were also higher in male controls than in the other three groups. Neither PBMC routine respiration and brain tissue oxidative phosphorylation nor maximal electron transfer capacity in the uncoupled state (ETC) showed any difference between ELS and controls. There was no significant relation between brain tissue and PBMC, ETC, or brain tissue, ETC, and PBMC bioenergetic health index. Whole blood O2 •¯ concentrations and PBMC O2 •¯ production were comparable between groups. However, granulocyte O2 •¯ production after stimulation with E. coli was lower in the ELS group, and this effect was sex-specific: increased O2 •¯ production increased upon stimulation in all control animals, which was abolished in the female ELS swine. Conclusion: This study provides evidence that ELS i) may, gender-specifically, affect the immune response to general anesthesia as well as O2 •¯ radical production at sexual maturity, ii) has limited effects on brain and peripheral blood immune cell mitochondrial respiratory activity, and iii) mitochondrial respiratory activity of peripheral blood immune cells and brain tissue do not correlate.

RESUMO

This longitudinal study aimed to explore anxiety and depressive symptoms, individual resources, and job demands in a multi-country sample of 612 healthcare workers (HCWs) during the COVID-19 pandemic. Two online surveys were distributed to HCWs in seven countries (Germany, Andorra, Ireland, Spain, Italy, Romania, Iran) during the first (May-October 2020, T1) and the second (February-April 2021, T2) phase of the pandemic, assessing sociodemographic characteristics, contact with COVID-19 patients, anxiety and depressive symptoms, self-compassion, sense of coherence, social support, risk perception, and health and safety at the workplace. HCWs reported a significant increase in depressive and anxiety symptoms. HCWs with high depressive or anxiety symptoms at T1 and T2 reported a history of mental illness and lower self-compassion and sense of coherence over time. Risk perception, self-compassion, sense of coherence, and social support were strong independent predictors of depressive and anxiety symptoms at T2, even after controlling for baseline depressive or anxiety symptoms and sociodemographic variables. These findings pointed out that HCWs during the COVID-19 outbreak experienced a high burden of psychological distress. The mental health and resilience of HCWs should be supported during disease outbreaks by instituting workplace interventions for psychological support.

RESUMO

Background: Different from the very early stages of the COVID-19 pandemic, burnout and chronic mental health problems among health care workers (HCWs) has become a challenge. Research is lacking on the relationship between burnout, stress, emotional distress and sleep quality. Methods: The Chinese center has been involved in the Cope-Corona project since the second survey (T2). Named after the project, a total of three cross-sectional surveys were distributed: T2 (February 16-20, 2021), T3 (May 10-14, 2022), and T4 (December 20-24, 2022). Burnout, depression, anxiety, sleep quality, workplace factors and individual resources were measured. Using the T4 data, we conducted structural equation model (SEM) to examine the mediating role of burnout in predicting emotional distress and sleep quality. Results: 96, 124, and 270 HCWs were enrolled at T2, T3, and T4, respectively. In line with the epidemic trends, the level of perceived COVID-19 related risks was significantly higher at T4, while the feeling of health and safety decreased significantly. At T4, the percentages of participants with clinically significant levels of depression and anxiety symptoms were 18.9% (51/270) and 9.3% (25/270), respectively, while 30.4% (82/270) of them reported poor or very poor sleep quality. According to the SEM, individual resources and workplace factors mainly had an indirect effect in predicting depression and anxiety via burnout. However, neither burnout nor stress was a mediator or predictor of sleep quality. Instead, individual resources, positive workplace factors, and younger age had a direct effect in predicting good sleep quality. Conclusion: Measures designed to enhance workplace factors and individual resources should be implemented to improve psychosomatic wellbeing of HCWs.
