RESUMO
AIMS: Compare and characterize Chaetomium strains with special regard to their potentialities as biocontrol agents. METHODS AND RESULTS: Twelve strains of the fungal genus Chaetomium from diverse ecological niches were identified as belonging to six different species. Large differences were observed between the strains with regard to temperature requirements for mycelial growth and pigmentation of culture filtrates. Culture filtrates and ethyl acetate extracts were assayed for fungicidal effects against important phytopathogens both on agar media and in multiwell plates. The samples from Chaetomium globosum were particularly active against Botrytis cinerea, Pyrenophora graminea and Bipolaris sorokiniana, while those from C. cochliodes and C. aureum were inhibitory towards Phytophthora infestans, and P. infestans and Fusarium culmorum respectively. To narrow down the active principle, the most promising extracts were separated by preparative HPLC and the resulting fractions tested in bioassays. Chaetoglobosins were identified as active compounds produced by C. globosum. CONCLUSIONS: The bioassays revealed C. aureum and C. cochliodes as promising candidates for use in biocontrol. Both showed remarkably good activity against the prominent plant pathogen P. infestans. SIGNIFICANCE AND IMPACT OF THE STUDY: We provide the first systematic study comparing six different Chaetomium species with regard to their use as biocontrol agents.

AIM: To analyse the associations of area deprivation and urban/rural traits with the incidence of type 1 diabetes in the German federal state of North Rhine-Westphalia. METHODS: Data of incident type 1 diabetes cases in children and adolescents aged <20 years between 2007 and 2014 were extracted from a population-based diabetes register. Population data, indicators of area deprivation and urban/rural traits at the municipality level (396 entities) were obtained from official statistics. Area deprivation was assessed in five groups based on quintiles of an index of multiple deprivation and its seven deprivation domains. Poisson regression accounting for spatial dependence was applied to investigate associations of area deprivation and urban/rural traits with type 1 diabetes incidence. RESULTS: Between 2007 and 2014, 6143 incident cases were reported (99% completeness); the crude incidence was 22.3 cases per 100 000 person-years. The incidence decreased with increasing employment and environmental deprivation (relative risk of the most vs. the least deprived municipalities: 0.905 [95% CI: 0.813, 1.007] and 0.839 [0.752, 0.937], respectively) but was not associated with the composite deprivation index. The incidence was higher in more peripheral, rural, smaller and less densely populated municipalities, and the strongest association was estimated for the location trait (relative risk of peripheral/very peripheral compared with very central location: 1.231 [1.044, 1.452]). CONCLUSIONS: The results suggest that the type 1 diabetes risk is higher in more remote, more rural, less densely populated and less deprived areas. Urban/rural traits were stronger predictors of type 1 diabetes risk than area deprivation indicators.

BACKGROUND: Impairments of social cognition are considered core features of schizophrenia and are established predictors of social functioning. However, affective aspects of social cognition including empathy have far less been studied than its cognitive dimensions. The role of empathy in the development of schizophrenia remains largely elusive. METHODS: Emotional and cognitive empathy were investigated in large sample of 120 individuals at Clinical High Risk of Psychosis (CHR-P) and compared with 50 patients with schizophrenia and 50 healthy controls. A behavioral empathy assessment, the Multifaceted Empathy Test, was implemented, and associations of empathy with cognition, social functioning, and symptoms were determined. RESULTS: Our findings demonstrated significant reductions of emotional empathy in individuals at CHR-P, while cognitive empathy appeared intact. Only individuals with schizophrenia showed significantly reduced scores of cognitive empathy compared to healthy controls and individuals at CHR-P. Individuals at CHR-P were characterized by significantly lower scores of emotional empathy and unspecific arousal for both positive and negative affective valences compared to matched healthy controls and patients with schizophrenia. Results also indicated a correlation of lower scores of emotional empathy and arousal with higher scores of prodromal symptoms. CONCLUSION: Findings suggest that the tendency to 'feel with' an interaction partner is reduced in individuals at CHR-P. Altered emotional reactivity may represent an additional, early vulnerability marker, even if cognitive mentalizing is grossly unimpaired in the prodromal stage. Different mechanisms might contribute to reductions of cognitive and emotional empathy in different stages of non-affective psychotic disorders and should be further explored.

BACKGROUND: The adequate allocation of inpatient care resources requires assumptions about the need for health care and how this need will be met. However, in current practice, these assumptions are often based on outdated methods (e.g. Hill-Burton Formula). This study evaluated floating catchment area (FCA) methods, which have been applied as measures of spatial accessibility, focusing on their ability to predict the need for health care in the inpatient sector in Germany. METHODS: We tested three FCA methods (enhanced (E2SFCA), modified (M2SFCA) and integrated (iFCA)) for their accuracy in predicting hospital visits regarding six medical diagnoses (atrial flutter/fibrillation, heart failure, femoral fracture, gonarthrosis, stroke, and epilepsy) on national level in Germany. We further used the closest provider approach for benchmark purposes. The predicted visits were compared with the actual visits for all six diagnoses using a correlation analysis and a maximum error from the actual visits of ± 5%, ± 10% and ± 15%. RESULTS: The analysis of 229 million distances between hospitals and population locations revealed a high and significant correlation of predicted with actual visits for all three FCA methods across all six diagnoses up to ρ = 0.79 (p < 0.001). Overall, all FCA methods showed a substantially higher correlation with actual hospital visits compared to the closest provider approach (up to ρ = 0.51; p < 0.001). Allowing a 5% error of the absolute values, the analysis revealed up to 13.4% correctly predicted hospital visits using the FCA methods (15% error: up to 32.5% correctly predicted hospital). Finally, the potential of the FCA methods could be revealed by using the actual hospital visits as the measure of hospital attractiveness, which returned very strong correlations with the actual hospital visits up to ρ = 0.99 (p < 0.001). CONCLUSION: We were able to demonstrate the impact of FCA measures regarding the prediction of hospital visits in non-emergency settings, and their superiority over commonly used methods (i.e. closest provider). However, hospital beds were inadequate as the measure of hospital attractiveness resulting in low accuracy of predicted hospital visits. More reliable measures must be integrated within the proposed methods. Still, this study strengthens the possibilities of FCA methods in health care planning beyond their original application in measuring spatial accessibility.

Genome-wide association studies have generally failed to identify polymorphisms associated with antidepressant response. Possible reasons include limited coverage of genetic variants that this study tried to address by exome genotyping and dense imputation. A meta-analysis of Genome-Based Therapeutic Drugs for Depression (GENDEP) and Sequenced Treatment Alternatives to Relieve Depression (STAR*D) studies was performed at the single-nucleotide polymorphism (SNP), gene and pathway levels. Coverage of genetic variants was increased compared with previous studies by adding exome genotypes to previously available genome-wide data and using the Haplotype Reference Consortium panel for imputation. Standard quality control was applied. Phenotypes were symptom improvement and remission after 12 weeks of antidepressant treatment. Significant findings were investigated in NEWMEDS consortium samples and Pharmacogenomic Research Network Antidepressant Medication Pharmacogenomic Study (PGRN-AMPS) for replication. A total of 7062 950 SNPs were analyzed in GENDEP (n=738) and STAR*D (n=1409). rs116692768 (P=1.80e-08, ITGA9 (integrin α9)) and rs76191705 (P=2.59e-08, NRXN3 (neurexin 3)) were significantly associated with symptom improvement during citalopram/escitalopram treatment. At the gene level, no consistent effect was found. At the pathway level, the Gene Ontology (GO) terms GO: 0005694 (chromosome) and GO: 0044427 (chromosomal part) were associated with improvement (corrected P=0.007 and 0.045, respectively). The association between rs116692768 and symptom improvement was replicated in PGRN-AMPS (P=0.047), whereas rs76191705 was not. The two SNPs did not replicate in NEWMEDS. ITGA9 codes for a membrane receptor for neurotrophins and NRXN3 is a transmembrane neuronal adhesion receptor involved in synaptic differentiation. Despite their meaningful biological rationale for being involved in antidepressant effect, replication was partial. Further studies may help in clarifying their role.

Few data are available concerning the role of risk markers for Alzheimer's disease (AD) in progression to AD dementia among subjects with mild cognitive impairment (MCI). We therefore investigated the role of well-known AD-associated single-nucleotide polymorphism (SNP) in the progression from MCI to AD dementia. Four independent MCI data sets were included in the analysis: (a) the German study on Aging, Cognition and Dementia in primary care patients (n=853); (b) the German Dementia Competence Network (n=812); (c) the Fundació ACE from Barcelona, Spain (n=1245); and (d) the MCI data set of the Amsterdam Dementia Cohort (n=306). The effects of single markers and combined polygenic scores were measured using Cox proportional hazards models and meta-analyses. The clusterin (CLU) locus was an independent genetic risk factor for MCI to AD progression (CLU rs9331888: hazard ratio (HR)=1.187 (1.054-1.32); P=0.0035). A polygenic score (PGS1) comprising nine established genome-wide AD risk loci predicted a small effect on the risk of MCI to AD progression in APOE-É4 (apolipoprotein E-É4) carriers (HR=1.746 (1.029-2.965); P=0.038). The novel AD loci reported by the International Genomics of Alzheimer's Project were not implicated in MCI to AD dementia progression. SNP-based polygenic risk scores comprising currently available AD genetic markers did not predict MCI to AD progression. We conclude that SNPs in CLU are potential markers for MCI to AD progression.

OBJECTIVE: An ecologic study on the level of districts was performed to evaluate the possible association between district type and risk of cancer in Bavaria, Southern Germany. METHODS: Cancer incidence data for the years 2003-2012 were obtained from the population-based cancer registry Bavaria according to sex and cancer site. Data on district type, socio-economic area deprivation, particulate matter exposure, tobacco consumption, and alcohol consumption were obtained from publicly available sources. The possible association between district type and cancer risk adjusted for age, socio-economic area deprivation, particulate matter exposure, tobacco consumption, and alcohol consumption was evaluated using multivariable multi-level negative binomial regression. RESULTS: We found a significantly reduced cancer risk in densely populated districts close to core cities and/or rural districts compared to core cities with respect to the cancer sites mouth and pharynx (women only), liver (both sexes), larynx (both sexes), lung (both sexes), melanoma of the skin (both sexes), mesothelioma (men only), connective and soft tissue (both sexes), corpus uteri, other urinary tract (men only), urinary bladder (both sexes), and non-Hodgkin lymphoma (both sexes). CONCLUSION: Our findings require further monitoring. Since the apparently increased cancer risk in core cities may be related to lifestyle factors, preventive measures against lifestyle-related cancer could be specifically targeted at populations in deprived core cities.

BACKGROUND: Hypertension is one of the most frequently diagnosed chronic conditions in Germany. Targeted prevention strategies and allocation of general practitioners where they are needed most are necessary to prevent severe complications arising from high blood pressure. However, data on chronic diseases in Germany are mostly available through survey data, which do not only underestimate the actual prevalence but are also only available on coarse spatial scales. The discussion of including area deprivation for planning of healthcare is still relatively young in Germany, although previous studies have shown that area deprivation is associated with adverse health outcomes, irrespective of individual characteristics. The aim of this study is therefore to analyze the spatial distribution of hypertension at very fine geographic scales and to assess location-specific associations between hypertension, socio-demographic population characteristics and area deprivation based on health insurance claims of the AOK Nordost. METHODS: To visualize the spatial distribution of hypertension prevalence at very fine geographic scales, we used the conditional autoregressive Besag-York-Mollié (BYM) model. Geographically weighted regression modelling (GWR) was applied to analyze the location-specific association of hypertension to area deprivation and further socio-demographic population characteristics. RESULTS: The sex- and age-adjusted prevalence of hypertension was 33.1% in 2012 and varied widely across northeastern Germany. The main risk factors for hypertension were proportions of insurants aged 45-64, 65 and older, area deprivation and proportion of persons commuting to work outside their residential municipality. The GWR model revealed important regional variations in the strength of the examined associations. CONCLUSION: Area deprivation has only a significant and therefore direct influence in large parts of Mecklenburg-West Pomerania. However, the spatially varying strength of the association between demographic variables and hypertension indicates that there also exists an indirect effect of area deprivation on the prevalence of hypertension. It can therefore be expected that persons ageing in deprived areas will be at greater risk of hypertension, irrespective of their individual characteristics. The future planning and allocation of primary healthcare in northeastern Germany would therefore greatly benefit from considering the effect of area deprivation.

BACKGROUND: A new strategy for planning outpatient medical care needs to be developed. The social and morbidity structure of the population should be considered in the planning of needs-based provision of medical care. This paper aims to examine the extent to which the degree of regional deprivation can be incorporated in the calculation of the regional requirements for specialists in Germany. METHODS: To measure regional deprivation status at district level, we used the "German Index of Multiple Deprivation" (GIMD) developed in the Helmholtz Zentrum München - German Research Center for Environmental Health. Scores were calculated for the deprivation status of each rural and urban district in Germany. The methods used to compute the deprivation-adjusted medical need are linear regression analyses. The analyses were based on regionalized data for the number of office-based physicians and their billing data. The analyses were carried out with the SPSS software package, version 20. RESULTS: The analyses showed a clear positive correlation between regional deprivation and the utilisation of medical services both for outpatients and in-patients, on the one hand, and mortality and morbidity, as measured by the risk adjustment factor (RSA), on the other. At the district level, the analyses also revealed varying associations between the degree of deprivation and the utilisation of the 12 groups of specialists included in the needs assessment. On this basis, an algorithm was developed by which deprivation at district level can be used to calculate an increase or a decrease in the relative number of specialists needed. DISCUSSION AND CONCLUSION: Using the GIMD and various determinants of medical utilisation, the model showed that medical need increased with the level of regional deprivation. However, regarding SHI medical specialist groups, the associations found in this analysis were statistically (R2) insufficient to suggest a needs assessment planning system based only on the factors analysed, thereby restricting physicians' constitutional right of professional freedom. In particular cases, i. e. licenses to meet special needs, the developed instruments may be suitable for indicating a greater or lesser need for doctors at a regional level due to their relative ease of use and practicability.

BACKGROUND: Dementia is a major challenge for society and its impact will grow in the future. Informal care is an essential part of dementia care. Previous studies considered informal care as a whole and not by its components. OBJECTIVE: We aimed to assess the degree of association between specific informal care services and dementia. MATERIAL AND METHODS: This analysis is based on data from the seventh wave of the AgeCoDe/AgeQualiDe study. Dementia was diagnosed based on the DSM-IV criteria. Severity of dementia was assessed and categorized by means of the Clinical Dementia Rating and eight individual informal care services were considered. Logistic regression models were used to assess associations. RESULTS: Of the 864 participants 18% suffered from dementia (very mild: 4%; mild: 6%; moderate: 5%; severe: 3%). All informal care services were significantly associated with dementia, with an emphasis on "supervision", "regulation of financial matters" and "assistance in the intake of medication". Considering different degrees of dementia severity, similar results arose from the analyses. All three aforementioned services showed a pronounced association with all degrees of dementia severity, except for supervision and very mild dementia. CONCLUSION: The provision of all types of informal care services is associated with dementia. The association is pronounced for services that can be more easily integrated into the daily routines of the informal caregiver. Policy makers who plan to integrate informal care into the general care arrangements for dementia should consider this.

In this article, the current literature on pharmacogenetics of antidepressants, antipsychotics and lithium are summarized by the section of Neurobiology and Genetics of the German Society of Psychiatry, Psychotherapy and Neurology (DGPPN). The publications of international expert groups and regulatory authorities are reviewed and discussed. In Germany, a statement on pharmacogenetics was also made by the gene diagnostics committee of the Ministry of Health. The DGPPN supports two recommendations: 1) to perform CYP2D6 genetic testing prior to prescription of tricyclic antidepressants and 2) to determine the HLA-B*1502 genotype in patients of Asian origin before using carbamazepine. The main obstacle for a broad application of pharmacogenetic tests in psychiatry remains the lack of large prospective studies, for both single gene-drug pair and cobinatorial pharmacogenetic tests, to evaluate the benefits of genetic testing. Psychiatrists, geneticists and funding agencies are encouraged to increase their efforts for the future benefit of psychiatric patients.

Genomic risk profile scores (GRPSs) have been shown to predict case-control status of schizophrenia (SCZ), albeit with varying sensitivity and specificity. The extent to which this variability in prediction accuracy is related to differences in sampling strategies is unknown. Danish population-based registers and Neonatal Biobanks were used to identify two independent incident data sets (denoted target and replication) comprising together 1861 cases with SCZ and 1706 controls. A third data set was a German prevalent sample with diagnoses assigned to 1773 SCZ cases and 2161 controls based on clinical interviews. GRPSs were calculated based on the genome-wide association results from the largest SCZ meta-analysis yet conducted. As measures of genetic risk prediction, Nagelkerke pseudo-R(2) and variance explained on the liability scale were calculated. GRPS for SCZ showed positive correlations with the number of psychiatric admissions across all P-value thresholds in both the incident and prevalent samples. In permutation-based test, Nagelkerke pseudo-R(2) values derived from samples enriched for frequently admitted cases were found to be significantly higher than for the full data sets (Ptarget=0.017, Preplication=0.04). Oversampling of frequently admitted cases further resulted in a higher proportion of variance explained on the liability scale (improvementtarget= 50%; improvementreplication= 162%). GRPSs are significantly correlated with chronicity of SCZ. Oversampling of cases with a high number of admissions significantly increased the amount of variance in liability explained by GRPS. This suggests that at least part of the effect of common single-nucleotide polymorphisms is on the deteriorative course of illness.

Background: Little is known about the longitudinal predictors of the need for care in old age. However, the knowledge of these factors is important for developing strategies for prevention or delay the need for care. Thus, we aimed at investigating the factors affecting the need for care in old age. Methods: In this population-based prospective cohort study (AgeCoDe, with n=3 217 individuals aged 75 years and above at baseline), the need for care was observed over 4.5 years. The need for care was quantified by the care level defined by the German Law (§ 15 SGB XI). Longitudinal predictors (sociodemographic variables, impairment in mobility/hearing/vision, dementia and depression) of the need for care were examined by using Random Effects Logit regressions. Results: Longitudinal regression analysis revealed that the probability of the need for care significantly increased with the occurrence of dementia (OR: 48.2), mobility impairments (aggravated walking, OR: 26.4; disability of walking, OR: 747.9) and age (e. g. 90 years and above vs.<80 years, OR: 32.3). The influence of family status, living conditions, visual impairment and depression on need for care was markedly smaller, and the effect of hearing impairments did not achieve statistical significance. Conclusion: In order to prevent or delay the need for care in old age, treatments should aim at preserving mobility and cognition. Due to demographic ageing, developing such programs is of major importance for health policy.

A 67-year-old man presented with fever, night sweat and abdominal complaints for about 4 weeks. Ultrasound and a computed tomography scan showed distinct ascites as the main finding, presenting as exsudate with predominating lymphoid cells. Because of long-term immunosuppressive therapy with the tumor necrosis factor (TNF)-α inhibitor golimumab for psoriasis, the suspicion for a possible tuberculous peritonitis arose. This was confirmed with an enzyme-linked immunospot assay, a high level of adenosine deaminase in the ascites and a peritoneum which was studded with multiple whitish nodules, corresponding to granulomas with giant cells. With a standard antituberculous regimen the symptoms were quickly relieved and finally complete restitution was achieved.

This paper explores causes, explanations and consequences of the negative image of psychiatry and develops recommendations for improvement. It is primarily based on a WPA guidance paper on how to combat the stigmatization of psychiatry and psychiatrists and a Medline search on related publications since 2010. Furthermore, focussing on potential causes and explanations, the authors performed a selective literature search regarding additional image-related issues such as mental health literacy and diagnostic and treatment issues. Underestimation of psychiatry results from both unjustified prejudices of the general public, mass media and healthcare professionals and psychiatry's own unfavourable coping with external and internal concerns. Issues related to unjustified devaluation of psychiatry include overestimation of coercion, associative stigma, lack of public knowledge, need to simplify complex mental issues, problem of the continuum between normality and psychopathology, competition with medical and non-medical disciplines and psychopharmacological treatment. Issues related to psychiatry's own contribution to being underestimated include lack of a clear professional identity, lack of biomarkers supporting clinical diagnoses, limited consensus about best treatment options, lack of collaboration with other medical disciplines and low recruitment rates among medical students. Recommendations are proposed for creating and representing a positive self-concept with different components. The negative image of psychiatry is not only due to unfavourable communication with the media, but is basically a problem of self-conceptualization. Much can be improved. However, psychiatry will remain a profession with an exceptional position among the medical disciplines, which should be seen as its specific strength.

BACKGROUND: Deprivation indices are increasingly being used to assess the effects of contextual factors on health. In Germany, the recently developed 'German Index of Multiple Deprivation (GIMD)' integrates various dimensions of regional deprivation. We aim to assess the validity of the GIMD through a recalculation using more recent rural and urban district level data and by analysing its association with mortality at the national level. METHODS: We calculated a new version of the GIMD based on data from 2007 to 2010 for all 412 rural and urban districts in Germany. Mortality was quantified using indirectly standardised mortality ratios (SMRs). Correlation analyses and Poisson regression analyses were used to assess the association between the GIMD scores and total mortality, as well as premature mortality (< 65 years). RESULTS: Correlation analyses showed a positive association between the GIMD and both total mortality (p<0.001) and premature mortality (p<0.001). In the Poisson regression analyses, rural and urban districts in the quintile with the highest deprivation showed a significantly elevated risk of total mortality (RR: 1.29; 95% CI: 1.28-1.30) as well as premature mortality (RR: 1.50; 95% CI: 1.47-1.53), compared to the districts in the lowest quintile. CONCLUSION: The association between regional deprivation and mortality has already been shown for the federal state of Bavaria. Using more recent data, this relationship could be confirmed here for Germany as a whole. The GIMD has been shown to be able to effectively assess regional deprivation. Concerning public health policy, the significant, positive and stable association between regional deprivation and mortality indicates an increased need for health care provision particularly in the most deprived districts. Further studies should examine, for example, whether and how the allocation of districts to quintiles of regional deprivation changes over time, and how this affects mortality.

Some mental and neurobiological disorders are associated with an increased risk for violence against others. The stigmatization of people with mental illnesses essentially emerges from a distorted perception of this condition. This review article summarizes the available literature on the determinants, prevention, therapy and tools for prediction of serious interpersonal aggression in the context of people with mental disorders. The risks for violence against other people show substantial variation between the various diagnoses. Schizophrenia and mania carry a clearly increased risk particularly at the onset of the disorder but disease-specific pharmacological therapy can reduce these risks. The highest risk factors are in particular previous violence, misuse of alcohol and drugs, male gender and young age. Probabilistic predictions of subsequent aggression against others on an individual-specific basis are only feasible in enriched populations (especially persons with mental illnesses and a previous history of assaults). Valid individual-specific predictions of future violence in the general population or on the basis of diagnoses of mental illness are, however, currently not feasible with sufficient accuracy.

BACKGROUND: Due to the high burden attributed to mental disorders, an important purpose of a general healthcare system is to provide comprehensive medical specialist care that is both locally available and in line with demand; however, the density of outpatient physicians and psychotherapists significantly varies between regions in Germany. To verify if these variations reflect regional variations of morbidity rates, routine data of statutory health insurance companies are analyzed on a regular basis. But these administrative data directly depend on the actual regional health care supply. Hence, independent epidemiological data on prevalence rates of mental disorders could be a valuable supplement. METHODS: Analyses are based on prevalence rates of the representative epidemiological German health interview and examination survey and its mental health module (DEGS1-MH) as well as supplemental data from the German national and regional associations of statutory health insurance physicians. The associations between prevalence rates and density of outpatient physicians and psychotherapists were computed for the DEGS sample points, representing 139 different German districts. Transregional care provision for neighboring regions was taken into account. RESULTS: There were neither significant associations of regional density of outpatient physicians and psychotherapists with prevalence rates of mental disorders in general nor with prevalence rates of severe mental disorders; however, taking into account transregional care provision for neighboring regions the huge variability of provider density decreases. DISCUSSION: The regional inequality of physician and psychotherapist density cannot be explained by regional differences in treatment needs. The results indicate potential improvements in healthcare provision for mental disorders in Germany through the adaptation to actual morbidity rates; however, the definition of treatment needs in mental disorders requires further evaluation.

BACKGROUND: Patients with mental illnesses, especially with schizophrenia, suffer from stigma and discrimination. In addition, the stigma is a barrier to recognising and treating patients with first-episode psychosis; however, a self-rating instrument that assesses the general burden due to stigma experiences is still lacking. MATERIAL AND METHODS: A total of N = 48 patients with first-episode schizophrenia who were participants in the multicenter first-episode (long-term) study within the German Research Network on Schizophrenia, completed a newly developed self-rating questionnaire to assess the burden due to stigma experiences (B-STE). The following variables were analyzed as possible correlates: psychopathology (CGI, PANSS, CDSS and HAM-D), global functioning (GAF), social adjustment (SAS), self-esteem (FSKN), as well as quality of life (LQLP), subjective well-being under neuroleptic treatment (SWN) and anticipated stigma (PDDQ). RESULTS: Of the participants 25 % showed an increased burden due to stigma experiences, which correlated with a lower quality of life, lower subjective well-being under neuroleptic treatment, lower self-esteem and higher anticipated stigma. The results indicate that patients rated higher on the CGI scale who are at the same time better socially adjusted (SAS), are more intensely affected by the burden due to stigma experiences. CONCLUSION: The short self-rating instrument burden due to stigma experiences (B-STE) can help to identify patients who might benefit from therapeutic or educational interventions to support coping with stigma experiences.

BACKGROUND: The German Research Network on Schizophrenia (GRNS) was funded by the Federal Ministry of Education and Research (BMBF) from 1999 to 2011. The aim was to obtain a better horizontal and vertical networking of German research and care facilities on schizophrenia, in order to investigate open research questions, to transfer the results into clinical practice and improve care and quality of life in patients with schizophrenia. OBJECTIVES/METHODS: This paper describes the concept and operations of the GRNS as well as its results on the basis of selected research projects. RESULTS: The GRNS comprised about 25 clinical trials of high practical relevance, which were closely interrelated regarding content, methodology and organization. The trials primarily served the development and evaluation of new and established diagnostic and therapeutic approaches, the assessment of the status quo of clinical care, as well as its improvements, together with the investigation of basic scientific questions. Many substantial results to highly relevant issues were obtained, which led or will lead to an improvement in mental health care. CONCLUSIONS: Quantitative and qualitative evaluation parameters, such as scientific publications and obtaining additional grants, as well as promotion of young scientists, public relations activities, congress activities and the foundation of a European Schizophrenia Association, document the successful work of the network. Successful funding requests will allow us to continue cooperative schizophrenia research in Germany as initiated by the GRNS, without necessarily always binding these activities formally to the GRNS.
