RESUMEN
Irisin has recently been proposed to act as a myokine secreted from skeletal muscle following exercise and to exert several health-beneficial effects, although its role is far from being established. In contrast to the growing body of literature on the biological regulation and function of irisin, there is no evidence on potential associations with mental functions. Since physical activity has been reported to have favorable impact on mental functions, we investigated the association of irisin with depressiveness, perceived stress, and anxiety as well as eating disorder symptoms in obese women. We included 98 female obese inpatients (age: mean ± S.D. 43.9 ± 12.5 years; body mass index 49.2 ± 8.3 kg/m(2)) covering a broad spectrum of psychopathology. Depressiveness (PHQ-9), perceived stress (PSQ-20), anxiety (GAD-7), and eating disorder symptoms (EDI-2) were assessed psychometrically. Plasma irisin obtained at the same time was determined by ELISA. Irisin did not correlate with depressiveness (r = -0.03, P = 0.80), anxiety (r = 0.14, P = 0.17) and perceived stress (r = -0.14, P = 0.18) as well as eating disorder symptoms in general (r = -0.09, P = 0.39). No correlation of irisin was observed with any subscales of the PSQ-20 and EDI-2 (after Bonferroni correction). In conclusion, irisin is not associated with depressiveness, anxiety and perceived stress in female obese patients. These results do not support the assumption of irisin being involved in psychoendocrine pathways of the regulation of depression or other mental functions such as anxiety and perceived stress.

Relaxation and meditation techniques are generally characterized by focusing attention, which is associated with an increase of frontal EEG Theta. Some studies on music perception suggest an activation of Frontal Midline Theta during emotionally positive attribution, others display a lateralization of electrocortical processes in the attribution of music induced emotion of different valence. The present study examined the effects of vibroacoustic stimulation using a Body Monochord and the conventional relaxation music from an audio CD on the spontaneous EEG of patients suffering from psychosomatic disorders (N = 60). Each treatment took about 20 min and was presented to the patients in random order. Subjective experience was recorded via self-rating scale. EEG power spectra of the Theta, Alpha-1 and Alpha-2 bands were analysed and compard between the two treatment conditions. There was no lateralization of electrocortical activity in terms of the emotional experience of the musical pieces. A reduction in Alpha-2 power occurred during both treatments. An emotionally positive attribution of the experience of the vibroacoustically induced relaxation state is characterized by a more pronounced release of control. In the context of focused attention this is interpreted as flow experience. The spontaneous EEG showed an increase in Theta power, particularly in the frontal medial and central medial area, and a greater reduction in Alpha-2 power. The intensity of positive emotional feelings during the CD music showed no significant effect on the increase in Theta power.

The ghrelin acylating enzyme ghrelin-O-acyltransferase (GOAT) was recently identified and implicated in several biological functions. However, the effects on food intake warrant further investigation. While several genetic GOAT mouse models showed normal food intake, acute blockade using a GOAT inhibitor resulted in reduced food intake. The underlying food intake microstructure remains to be established. In the present study we used an automated feeding monitoring system to assess food intake and the food intake microstructure. First, we validated the basal food intake and feeding behavior in rats using the automated monitoring system. Afterwards, we assessed the food intake microstructure following intraperitoneal injection of the GOAT inhibitor, GO-CoA-Tat (32, 96 and 288 µg/kg) in freely fed male Sprague-Dawley rats. Rats showed a rapid habituation to the automated food intake monitoring system and food intake levels were similar compared to manual monitoring (P = 0.43). Rats housed under these conditions showed a physiological behavioral satiety sequence. Injection of the GOAT inhibitor resulted in a dose-dependent reduction of food intake with a maximum effect observed after 96 mg/kg (-27%, P = 0.03) compared to vehicle. This effect was delayed in onset as the first meal was not altered and lasted for a period of 2 h. Analysis of the food intake microstructure showed that the anorexigenic effect was due to a reduction of meal frequency (-15%, P = 0.04), whereas meal size (P = 0.29) was not altered compared to vehicle. In summary, pharmacological blockade of GOAT reduces dark phase food intake by an increase of satiety while satiation is not affected.

Transforming growth factor-ßs (TGF-ßs) are secreted from cells as latent complexes and the activity of TGF-ßs is controlled predominantly through activation of these complexes. Tolerance to the fetal allograft is essential for pregnancy success; TGF-ß1 and TGF-ß2 play important roles in regulating these processes. Pregnancy-specific ß-glycoproteins (PSGs) are present in the maternal circulation at a high concentration throughout pregnancy and have been proposed to have anti-inflammatory functions. We found that recombinant and native PSG1 activate TGF-ß1 and TGF-ß2 in vitro. Consistent with these findings, administration of PSG1 protected mice from dextran sodium sulfate (DSS)-induced colitis, reduced the secretion of pro-inflammatory cytokines, and increased the number of T regulatory cells. The PSG1-mediated protection was greatly inhibited by the coadministration of neutralizing anti-TGF-ß antibody. Our results indicate that proteins secreted by the placenta directly contribute to the generation of active TGF-ß and identify PSG1 as one of the few known biological activators of TGF-ß2.

PURPOSE: Known association between tinnitus and psychological distress prompted us to examine patients with chronic tinnitus by using the Composite International Diagnostic Interview (CIDI), which is a standardized and reliable method used for the diagnosis of mental disorders. METHODS: One hundred patients with chronic tinnitus admitted to the Tinnitus Center, Charité-Universitätsmedizin Berlin, were included in this study. Data were collected between February 2008 and February 2009. Besides CIDI, the Tinnitus Questionnaire according to Goebel and Hiller, the Hospital Anxiety Depression Scale, and the General Anxiety Disorder-7 were used. RESULTS: Using CIDI, we have identified one or more mental disorders in 46 tinnitus patients. In that group, we found persistent affective disorders (37 %), anxiety disorders (32 %), and somatoform disorders (27 %). Those patients who had affective or anxiety disorders were more distressed by tinnitus and were more anxious and more depressed than tinnitus patients without mental disorders. Psychological impairment positively correlated with tinnitus distress: Patients with decompensated tinnitus had significantly more affective and anxiety disorders than patients with compensated tinnitus. CONCLUSIONS: In the present study, we have detected a high rate (almost half of the cases) of psychological disorders occurring in patients with chronic tinnitus. The patients diagnosed with psychological disorders were predominantly affected by affective and anxiety disorders. Psychological disorders were associated with severity of tinnitus distress. Our findings imply a need for routine comprehensive screening of mental disorders in patients with chronic tinnitus.

Chronic somatic pain disorders with somatic and mental factors (ICD-10: F45.41) are common among psychosomatic patients. In the present case, due to the close temporal association with a trauma and the subsequent development of symptoms including depressive symptoms, a chronic pain disorder with a relevant somatoform component was suspected. However, after a period of several months without significant somatic findings, targeted diagnostic approaches resulted in the diagnoses of primary hyperparathyroidism and a papillary thyroid carcinoma. Surgical therapy resulted in an almost complete decline of symptoms within a short period of time.

Anorexia nervosa is a severe illness and shows one of the highest death rates among psychiatric or psychosomatic diseases. However, despite several lines of research, the etiology of this disease is still unknown. One of those features is the rigidity of behaviors, for example, controlling of weight and pursuing of thinness, that often meets the criteria for obsessive-compulsive behavior. In this study, it was investigated whether the clinical feature of compulsivity in anorexia nervosa patients relates to regional brain activation. Using functional magnetic resonance imaging, 12 severely anorectic women were compared to 12 normal-weight female individuals following a cue-reactivity paradigm. Cues comprised food cues of high and low calorie content as well as eating-related utensils. Voxel-based morphometric analysis indicated significantly overall reduced gray matter volume and significantly increased cerebrospinal fluids in anorexia nervosa (AN) patients, which was controlled for in subsequent analyses. Following the high-calorie stimulation, AN patients activated the right caudate body and right precuneus, whereas control subjects did not show significant regional activations. In both other conditions, low-calorie foods and eating utensils, regional brain activations did not survive FDR thresholds. During the high-calorie condition, compulsivity, that is, the subscore "obsessive thoughts," predicted activation of the superior frontal gyrus [Brodmann areas (BA) 10], inferior frontal gyrus, anterior cingulate cortex (BA 32), cingulate gyrus (BA 24), caudate body, cuneus, pre- and postcentral gyrus. The subscore "compulsive acts" correlated with activation of the claustrum during the high-calorie condition and predicted a number of deactivations of frontal and temporal regions. We conclude that in severely anorectic individuals, the degree of compulsivity predicts activation and deactivation of the fronto-striatal pathway.

AIM: The aim of the present study was to define, besides prevalence data, regional and individual factors of stress experience in a representative sample of the German general population. METHODS: Regional factors were examined separately by federal state and the size of the political location. Individual factors were defined according to the severity of the stress experience as well as on the basis of central social factors such as family state, profession and earnings. The Perceived Stress Questionnaire (PSQ), a validated, self-evaluation process for recording a subjective representation of frequency estimates of stress experiences was used. Data acquisition was carried out by a market research institute in a multi-topic questionnaire (N=2,552). Households were selected by the random route procedure, target persons were also selected at random. RESULTS: The prevalence rate for an elevated stress experience was 14.5%, that for a very high stress experience 3.1% of the sample. People without education exhibited the highest rates of stress experience (36.8%), followed by the unemployed (30.6%). Individual and social factors that favour an increased stress experience are a subjectively poor state of health (OR: 3.42) or belonging to the lower social economic status (OR: 1.30). Furthermore, there are indications of regional factors such as size of the location as well as differences between the individual federal states. An east-west comparion did not show any significant differences with regard to stress experiences. CONCLUSION: In the light of the illness burden associated with chronic stress situations, preventative measures in cases of unemployment or low level of education should be given priority.

The psychological evaluation of living liver donors is a substantial part of the preoperative evaluation of donors in many transplantation centres around the globe and aims at securing decision autonomy and informed consent, verifying the psychological stability of the donor and ruling out psychosocial risks. The aims of this paper are to present a short overview of the current state of the psychosocial evaluation of living donors based on the existing literature and to discuss our centre's experience in the psychological evaluation of donors, the lessons we have learned in the past 10 years and an agenda for the future evaluation of donors and research.

Peripheral and central structures are involved in the onset of tinnitus. Neuronal plasticity is of special importance for the occurrence of central tinnitus and its persistent form. Neuronal plasticity is the ability of the brain to adapt its own structure (synapses, nerve cells, or even whole areas of the brain) and its organization to modified biological requirements. Neuroplasticity is an ongoing dynamic process. Generally speaking, there are two types of plasticity: synaptic and cortical. Cortical plasticity involves activity-dependent changes in size, connectivity, or in the activation pattern of cortical networks. Synaptic plasticity refers to the activity-dependent change in the strength of synaptic transmission and can affect both the morphology and physiology of the synapse. The stimulation of afferent fibers leads to long-lasting changes in synaptic transmission. This phenomenon is called long-term potentiation (LTP) or long-term depression (LTD). From the perspective of molecular biology, synaptic plasticity is of particular importance for the development of tinnitus and its persistence. Ultimately, the damage to the hair cells, auditory nerve, and excitotoxicity results in an imbalance between LTP and LTD and thus in changes of synaptic plasticity. After excessive acoustic stimulation, LTP can be induced by the increase of afferent inputs, whereas decreased afferent inputs generate LTD. The imbalance between LTP and LTD leads to changes in gene expression and involves changes in neurotransmission, in the expression of the receptors, ion channels, regulatory enzymes, and in direct changes on the synapses. This causes an increase of activity on the cellular level. As a result, the imbalance can lead to hyperactivity in the dorsal cochlear nucleus, inferior colliculus, and in the auditory cortex and, later on, to changes in cortical plasticity leading to tinnitus.

BACKGROUND: Narcissism is seen as a normal but heterogeneously formed personality variable, ranging from 'grandiosity-exhibitionism' to 'vulnerability-sensitivity'. This article reports the development and factorial validation of a short version of a narcissism inventory. SAMPLING AND METHODS: The sample includes data of 4,509 consecutive psychosomatic inpatients. The overall sample was divided in 2 equally sized randomized subsamples. One sample (n = 2,262) was used for exploratory factor analysis (principal component analysis). The other sample (n = 2,265) was used for confirmatory tests of the model fit of the newly built NI-20 version, and to analyze the model fit separately for men and women using structural equation modeling with AMOS software. RESULTS: The short version (NI-20) consists of 20 items, with items representing almost all of the original 18 subscales and 4 second-order dimensions. The NI-20 possesses properties similar to the NI-90, with a considerable gain in test economy. The 4-factor structure of the NI-20 was confirmed, and reaches good fit indices. CONCLUSIONS: The NI-20 is an economical instrument with acceptable psychometric characteristics that reflects the heterogeneous aspects of narcissism. A methodological limitation is that the interactions between sociodemographic variables were not included as potential predictors.

Emotional stress is often associated with auditory phenomena such as hyperacusis, tinnitus, Ménière's disease and vertigo. Stress develops as a result of a person's attempts to come to terms with the increased or unexpected demands of his or her environment. Stress serves to protect one from physical danger and to temporarily increase one's performance in order to increase the probability of survival. Sleep and appetite are particularly reduced, while anxiety increases. The mental changes induced by stress may contribute to the onset or exacerbation of tinnitus. The following links exist between the auditory and stress systems: the limbic system, which regulates instinctive behavior and emotions, is linked to the auditory system via the medial geniculate body (amygdala). The hypothalamus, which is the integrative center of the endocrine and autonomic systems, is linked to the auditory system via the inferior colliculus. The reticular system, which is focused on the behavior pattern of attention and excitement, projects serotonergic fibers to all pathways of the auditory system, ranging from the cochlea to the auditory cortex.

The success of mammalian pregnancy is highly dependent on the establishment of an adequate blood supply to support the metabolic demands of the growing embryo and fetus. New blood vessels develop from pre-existing vessels in a multi-step process called angiogenesis, which is tightly regulated in time and space and has proven to be crucial in several physiological situations such as wound healing, follicular development and cyclic endometrial growth. As in other tissues, the regulation of angiogenic responses in the decidua depends on a delicate balance between stimulatory and inhibitory signals. In particular, trophoblasts and decidual NK cells are well-recognized components of the uterine signaling network with a proven ability to produce growth factors and cytokines that modulate endothelial cell responsiveness during pregnancy. In mice and humans, dendritic cells are also considered an important regulatory component during pregnancy, mainly due to their role in the establishment of maternal immunologic tolerance. However, the recent finding that dendritic cell subsets can promote angiogenesis in a variety of physiopathological settings suggests that regulatory functions of these cells may go beyond the promotion of maternal tolerance, having impact on other processes such as decidualization and placentation and the vascular changes associated to them. Current evidence on dendritic cell-derived angiogenic signals and their potential implications in vascular development during gestation are reviewed and discussed herein.

BACKGROUND: In recent years, data from questionnaires have demonstrated increasing criticism from junior physicians regarding their work conditions. Ideally, such subjective statements should be compared to accurate objective data regarding workload. However, such data is not available in the research literature. Therefore the aim of the current study is to deliver exact data about physicians' work in different gastroenterology departments to analyze and to optimize work routines. METHOD: An observational real-time study was conducted by shadowing 21 gastroenterologists individually during weekday shifts at three hospitals in urban German settings. A total of 585 hours of observations were recorded by using an ultra mobile computer. RESULTS: The observation results have shown that a gastroenterologist's working day lasted on an average 9 hours 16 min (SD = 1:11:18 h). The following amount of time was given to varying tasks within this time period: 30.21 % for meetings (SD = 8.54 %), 13.42 % for documentation duties (SD = 7.74 %), 15.53 % for indirect patient care (SD = 6.32 %), 7.98 % for hospital admissions and ward rounds (SD = 5.49 %). Doctor patient communication was restricted to 4.05 % of the working day (SD = 2.71 %). CONCLUSION: This is the first real time analysis on how hospital gastroenterologists spend their working hours. Some of the problems with work routine reported by the doctors themselves were partly confirmed. With regard to the study results a rearrangement of job tasks coupled with technological solutions may prove helpful in reducing the burden on gastroenterologists and thereby improving the quality of medical care.

An important aspect in the preoperative evaluation and a legal precondition for an living donor liver transplantation (LDLT) is a family or emotionally close relationship between donor and recipient. We investigated the development of the donor-recipient relationship after LDLT. We conducted semi-structured clinical interviews with 18 donors as part of a regular postoperative follow-up and analyzed them using the method of Grounded Theory. The donation does not lead to any major changes in the donor-recipient relationship, probably due to careful pre-selection. It does however enhance the existing positive or conflicting character of the relationship. Donors sometimes downplay negative aspects in the relationship and emphasize the improvement as a way of dealing with a major life event. A donation cannot fulfill expectations linked to it and it is unfavorable to be used to improve the relationship. Potential misuse or instrumentalization of the donation by the donor are possible. Postoperative feelings of gratitude are an issue after surgery. A good relationship enhances a better management of the postoperative course. The preoperative donor-recipient relationship should be as free of conflict as possible. A thorough preoperative evaluation of the donor-recipient relationship is particularly important to assess the donors' suitability and clarify conflicts and unrealistic expectations.

Living donor liver transplantation is increasing as an effort to overcome the organ shortage for patients with terminal liver diseases. To maintain high medical and ethical standards, donors are evaluated before and after donation to assess their suitability, monitor their postoperative courses, and minimize risks. A psychological/psychosocial evaluation is included in the assessment at most transplantation centers. Due to the high risk and the challenging process of recovery and integration of the experience into one's life, it is important to identify donors with suitable psychological/psychosocial profiles. The psychosocial evaluation is performed on the basis of medical ethical standards, common sense, professional experience, and only a few systematic observations. Some studies have identified factors, such as complications for the recipient, as a possible influence on the donor's postoperative course, while others have sought to link donor outcomes with scores on psychometric instruments prior to donation. We suggest that it is not one, but the interplay of several factors that affects the donor's postoperative course, including decision autonomy and embedding the donation into a meaningful context, in addition to coping skills and recipient outcome. Based on pilot data, clinical observations, and a study of the literature, we developed a model of risk and protective factors influencing the donors' postoperative courses, which could be used to assess living liver donors psychosocially before and after donation, thus enhancing selection and support.

Endometriosis is a widespread chronic disease characterized by endometrial tissue located outside the uterine cavity. Clinical signs are chronic pelvic pain and infertility. Emerging evidence indicates that the immune system is profoundly involved in the onset and/or progression of endometriosis. However, mechanistic pathways have not yet been conclusively specified. In this study, women undergoing diagnostic laparoscopy due to infertility were recruited, and classified as early-stage endometriosis (n=30), advanced-stage endometriosis (n=8) or no endometriosis (n=31). The frequency and phenotype of leukocytes were evaluated in peritoneal fluid. While the frequency of lymphocytes was not significantly different, neutrophils were increased in endometriosis. Flow cytometry analysis revealed an increased frequency of CD4(+) and CD8(+) cells in peritoneal fluid of endometriosis patients. In addition, the frequency of CD4(+)CD25(+)CD103(+) cells and lineage(-)HLA-DR(+)CD11c(+)CD123(+) dendritic cells was decreased in peritoneal fluid in endometriosis, whereas CD57(+) NK cells and CD8(+)CD28(-) T suppressor cells remained largely unaltered. We conclude that therapeutic approaches in endometriosis might focus on peritoneal leukocytes as a target or surveillance marker; however, immune alterations in peritoneal fluid are subtle and their analysis will require highly standardized and harmonized protocols.

Tolerance to the developing fetus is thought to be accomplished through the action of several molecules that are able to modulate the maternal immune response. Among several mechanisms involved in pregnancy maintenance, progesterone-induced immunomodulation, asymmetric antibody (AAb) production, indoleamine 2,3-dioxygenase (IDO)-mediated tryptophan catabolism and Th1- to Th2-type cytokine balance have been particularly well studied. However, spontaneous abortions (SA) remain the most common complication of pregnancy, affecting 15% of women, primarily in the first trimester. Development of sensitive methods for the early diagnosis of this condition is therefore a matter of critical importance. In the present study, we investigated AAb production and IDO activity in pregnant women in order to assess their value as early markers for the diagnosis of pregnancy failure. Serum AAb percentages were significantly reduced in women who subsequently suffered from SA compared with controls (p<0.001). Levels of IL-10, IL-12 and IDO activity were also lower in the SA cases, although levels of significance were not reached. In view of these findings, low maternal serum AAb percentages during the first trimester of pregnancy may be indicative of a threat to pregnancy progression.

AIM OF THE STUDY: The therapy of the chronic tinnitus is aimed at improving the way patients cope with their tinnitus and at reducing the tinnitus-related distress. The present study investigated the changes of psychometric parameters that occurred in patients with chronic tinnitus after 7-days outpatient multidisciplinary therapy. The changes were monitored for up to 1 year in order to evaluate the long-term efficiency. METHODS: Main emphasis of the intensive tinnitus therapy applied was placed on tinnitus habituation and on teaching the patients how to apply coping strategies. The main elements of the multimodal concept included progressive muscle relaxation according to Jacobson, physiotherapy, educative seminars, training of selective attention and, lastly, the change of judgment, attitude and behaviour towards tinnitus. Psychometric parameters and tinnitus-related distress were assessed prior to and after the therapy (at 3, 6 and 12 months) using the tinnitus questionnaire (TQ) according to Goebel and Hiller. Furthermore, subjects waiting for therapy (waiting list) were recruited to the control group and compared with the therapy group which had received therapy 3 months earlier. RESULTS: The therapy group showed a significant reduction of the TQ total score after 3 months as compared to the control group. Moreover, we observed a long-term, progressive positive outcome during the one-year follow-up. The TQ total score was reduced by 10.9 points. There was an obvious decrease of the emotional and cognitive distress as well as of the intrusiveness of tinnitus, as per evaluation of TQ subscales. CONCLUSIONS: The outpatient intensive multidisciplinary tinnitus therapy with long-term aftercare has proved to be an effective method in the treatment of patients with chronic tinnitus.

OBJECTIVE: The study aims to describe the prevalence of violent physical and sexual experiences in female outpatients and to identify specific gynaecological symptoms that are associated with a history of abuse. STUDY DESIGN: We performed a cross-sectional study among native German women. The confidential self-administered questionnaire included items on physical and sexual abuse and on the patient's medical history. Of a total of 1941 eligible women, 730 (37.6%) participated in the survey. We calculated prevalence rates of physical and sexual abuse and compared victims and non-victims of violence with respect to specific symptoms and complaints. We developed multivariate models for pelvic pain and vaginal infection. RESULTS: The lifetime prevalence of severe physical violence by any kind of perpetrator was 35.5%. 13.5% of participants reported a completed rape. The lifetime prevalence of physical and/or sexual intimate partner violence (IPV) was 28.3%. Physical and sexual abuse is significantly associated with irregular menstrual cycle, urinary tract infections and pelvic pain independent of menses. CONCLUSIONS: Physical and sexual violence are associated with many gynecological symptoms. Especially gynecologists and general practitioners have to be aware that their patients might be victims of violence. This is important for adequate diagnosis and therapy and to avoid retraumatization in affected women.
