Abstract
Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available.

Abstract
Tularemia is a highly contagious infectious zoonosis, transmissible by inoculation, ingestion, or inhalation of the infectious agent Francisella tularensis. The disease is perpetuated by infected rodents, blood-sucking arthropods, and by contaminated water. Therefore, nonhuman primates housed outdoors may be at risk for exposure. An epizootic of F. tularensis occurred in an indoor/outdoor-housed group of cynomolgus monkeys ( Macaca fascicularis) at the German Primate Center. Tularemia was diagnosed in 18 out of 35 animals within a period of 2 years. Six animals died with unspecific clinical symptoms; 12 animals developed seroconversion and were still alive. Pathologic findings were similar in all monkeys that died and resembled the clinical picture of the human disease, including an ulceroglandular syndrome with local lymphadenopathy, gingivostomatitis, and systemic spread, with manifestations such as subacute necrotizing hepatitis, granulomatous splenitis, and pneumonia. Tularemia was diagnosed by culture, real-time polymerase chain reaction, and ELISA techniques. This is the largest outbreak in nonhuman primates and the first report of tularemia in cynomolgus monkeys. An overview of the recent literature about tularemia in nonhuman primates is given.

Abstract
In a recent paper, Arita et al. [Phys. Rev. E 90, 052108 (2014)PLEEE81539-375510.1103/PhysRevE.90.052108] consider the transport properties of a class of generalized exclusion processes. Analytical expressions for the transport-diffusion coefficient are derived by ignoring correlations. It is claimed that these expressions become exact in the hydrodynamic limit. In this Comment, we point out that (i) the influence of correlations upon the diffusion does not vanish in the hydrodynamic limit, and (ii) the expressions for the self- and transport diffusion derived by Arita et al. are special cases of results derived in Becker et al. [Phys. Rev. Lett. 111, 110601 (2013)PRLTAO0031-900710.1103/PhysRevLett.111.110601].

Abstract
BACKGROUND The surgical treatment of pancreatic head tumours is one of the most complex procedures in general surgery. In contrast to colorectal surgery, minimally-invasive techniques are not very commonly applied in pancreatic surgery. Both the delicate dissection along peri- and retropancreatic vessels and the extrahepatic bile ducts and subsequent reconstruction are very demanding with rigid standard laparoscopic instruments. The 4-arm robotic surgery system with angled instruments, unidirectional movement of instruments with adjustable transmission, tremor elimination and a stable, surgeon-controlled 3D-HD view is a promising platform to overcome the limitations of standard laparoscopic surgery regarding precise dissection and reconstruction in pancreatic surgery. INDICATION Pancreatic head resection for mixed-type IPMN of the pancreatic head. PROCEDURE Robot-assisted, minimally-invasive pylorus-preserving pancreaticoduodenectomy (Kausch-Whipple procedure). CONCLUSION The robotic approach is particularly suited for complex procedures such as pylorus-preserving pancreatic head resections. The fully robotic Kausch-Whipple procedure is technically feasible and safe. The advantages of the robotic system are apparent in the delicate dissection near vascular structures, in lymph node dissection, the precise dissection of the uncinate process and, especially, bile duct and pancreatic anastomosis.

Abstract
BACKGROUND Abdominothoracic oesophageal resections, also known as Ivor Lewis procedures, are complex visceral surgery procedures. In recent years, substeps have increasingly been performed using minimally invasive techniques. However, intrathoracic anastomosis is still a challenge given the instrumental and technological possibilities available to date. This article provides a detailed description of the use of the Da Vinci robotic system and our techniques in oesophageal surgery. METHODS In a prospective data collection, we analysed the robotic-assisted oesophageal surgeries performed at the University Hospital of Schleswig-Holstein, Campus Kiel, between November 2013 and November 2015. RESULTS A total of 56 patients underwent robotic-assisted oesophageal surgery, with 43 patients undergoing the Ivor Lewis technique, 10 patients undergoing the McKeown procedure and 3 patients undergoing enucleation of a leiomyoma. A complete tumour resection (R0 margin) was achieved in 53 patients (93.4%); the mean number of resected lymph nodes was 23 (14-75). Forty-five (80.5%) patients received an induction therapy. Mean operative time was 412 min (120-610); mean hospital stay was 19 days (4-145). A conversion to open surgery was necessary in 19 (34.1%) cases, most notably in the thoracic part of the surgical procedure (17 patients). Forty-three patients received intrathoracic oesophagogastrostomy; 4 out of 5 patients with an initial side-to-side anastomosis developed a leakage, whereupon the technique was switched to a hand-sewn procedure (leakage in 3 out of 20 patients). Other major morbidities included leakage of the gastric conduit in 2 patients (3.6%), airway fistula in 2 patients (3.6%), mesenteric ischaemia in one patient (1.8%), and peritonitis due to a dislocated feeding tube in one other patient. Pulmonary complications occurred in 19 patients (34%). Four patients (7.1%) died of pulmonary embolism, heart attack, and septic organ failure. CONCLUSION Robotic-assisted, minimally invasive oesophagectomy is a feasible and useful approach for oncological surgery. This technique should be implemented in a structured program with an extensive and critical evaluation of the users' own results and an exchange with other experienced work teams. This helps to avoid pitfalls and to speed up the learning curve. Further technological developments and increasing experience might lead to a more widespread use of this technique.

Abstract
Variation in genes coding for nicotinic acetylcholine receptor (nAChR) subunits affect cognitive processes and may contribute to the genetic architecture of neuropsychiatric disorders. Single nucleotide polymorphisms (SNPs) in the CHRNA4 gene that codes for the alpha4 subunit of alpha4/beta2-containing receptors have previously been implicated in aspects of (mostly visual) attention and smoking-related behavioral measures. Here we investigated the effects of six synonymous but functional CHRNA4 exon 5 SNPs on the N100 event-related potential (ERP), an electrophysiological endophenotype elicited by a standard auditory oddball. A total of N = 1,705 subjects randomly selected from the general population were studied with electroencephalography (EEG) as part of the German Multicenter Study on nicotine addiction. Two of the six variants, rs1044396 and neighboring rs1044397, were significantly associated with N100 amplitude. This effect was pronounced in females where we also observed an effect on reaction time. Sequencing of the complete exon 5 region in the population sample excluded the existence of additional/functional variants that may be responsible for the observed effects. This is the first large-scale population-based study investigation the effects of CHRNA4 SNPs on brain activity measures related to stimulus processing and attention. Our results provide further evidence that common synonymous CHRNA4 exon 5 SNPs affect cognitive processes and suggest that they also play a role in the auditory system. As N100 amplitude reduction is considered a schizophrenia-related endophenotype the SNPs studied here may also be associated with schizophrenia outcome measures.

Abstract
BackgroundPsychosocial interventions are essential tools in mental health care and rehabilitation. A range of interventions relevant to rehabilitation that are covered in a German DGPPN S3 guideline on psychosocial interventions are discussed.MethodsLiterature search and (mostly) systematic reviews were performed for a range of psychosocial interventions.FindingsMilieu therapy (MT) includes measures that impinge on therapeutic milieu/atmosphere in joint professional/user groups in the course of treatment. MT provides a context in which psychosocial interventions can be implemented. There is evidence of its effectiveness in improving mental health outcomes. Peer involvement (PI) and peer support are supported by promising evidence as innovative interventions in mental health care. Findings on case management (CM) are inconsistent. There are difficulties in defining CM. CM strengths include treatment satisfaction and continuity of care. With respect to integration in the labour market for people with severe mental illness supported employment (SE) has been shown to be more effective in achieving job placement. A proportion of SE users fail to find jobs on the general labour market. Other types of work rehabilitation are required, and there is room for pre-vocational training interventions.DiscussionPsychosocial interventions are strong interventions. The strength of the evidence is varied. The use of psychosocial interventions rests on experience, evidence and ethics.ConclusionsPsychosocial interventions are indispensable in building mental health care systems. Vocational interventions and residential services are mandatory. Peer involvement could help in moving mental health services forward.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Home Treatment (HT) means acute psychiatric treatment in the patient's usual environment. Conceptually, HT is to be differentiated from other home-based services: It is limited with regard to duration and multiprofessional (e. g. psychiatrist plus psychiatric nursing staff plus social worker); the "24/7"-accessibility is frequently provided by the corresponding background hospital infrastructure. Target group are acutely mentally ill persons with an indication to inpatient treatment, who are willing to cooperate, and absence of endangerment to self and others. In contrast to the Scandinavian and many Anglophone countries where nationwide HT services are delivered, there are not many HT sites in Germany so far. Consequently, empirical data concerning HT in Germany is scarce. In summary, international studies show equivalent effects on psychopathological measures compared to inpatient treatment, reductions with regard to inpatient days, higher patient satisfaction and a trend towards cost-effectivity.

Abstract
Structural polymers such as cereal β-glucan may cause various processing problems in beverage industry depending on concentration, molar size distribution and agglomeration behaviour. In this context, influences of the beer volatiles dodecanoic acid, octyl butanoate, ethyl decanoate and decyl acetate on molar mass and radii of barley β-glucan were investigated in ethanolic (4% w/w) model solution. After addition of 100mg/l ethyl decanoate and decyl acetate to the β-glucan solution, a wider-ranging molar mass distribution could be observed by means of asymmetric field-flow-fractionation. Due to agglomeration, average molar mass of β-glucan standard (MW=6.8×10(6)g/mol) increased by 2×10(6)g/mol (P<0.05) in solution containing decyl acetate. Furthermore, a significant growth (P<0.05) from 86 to 102 nm in gyration radius was measured. The obtained results elucidate the importance of fatty acid derived flavouring substance composition in beer regarding the aggregation behaviour of β-glucan.

Abstract
In the light of historical and modern criticism of the discipline of psychiatry and psychotherapy as a medical subspecialty, this paper deals with aspects of the theory of medicine as postulated by the physician and philosopher Wolfgang Wieland. According to his contributions medicine is a practical science aiming at establishing rational action. Central to this model is a diagnosis, which helps to subsume individual cases under general principles from which essential therapeutic options can be derived. Hence, psychiatry and psychotherapy become a medical subspecialty by adopting the basic model of medical reasoning and action as described by Wieland. Nevertheless, the limits of such an approach must be taken into consideration. Especially in a psychiatric and psychotherapeutic context it is of particular importance that even when being guided by general principles the responsibility for the personality of each individual patient should be adequately met. Furthermore, attention should be paid to the limits of the subspecialty of psychiatry and psychotherapy as a medical discipline, which also requires a critical analysis of the concept of psychiatric illness.

Abstract
Data processing requires a robust linear fit identification method. In this paper, we introduce a non-parametric robust linear fit identification method for time series. The method uses an indicator 2/n to identify linear fit, where n is number of terms in a series. The ratio Rmax of amax− amin and Sn− amin*n and that of Rmin of amax− amin and amax*n − Sn are always equal to 2/n, where amax is the maximum element, amin is the minimum element and Sn is the sum of all elements. If any series expected to follow y = c consists of data that do not agree with y = c form, Rmax> 2/n and Rmin> 2/n imply that the maximum and minimum elements, respectively, do not agree with linear fit. We define threshold values for outliers and noise detection as 2/n * (1 + k1) and 2/n * (1 + k2), respectively, where k1 > k2 and 0 ≤ k1≤ n/2 − 1. Given this relation and transformation technique, which transforms data into the form y = c, we show that removing all data that do not agree with linear fit is possible. Furthermore, the method is independent of the number of data points, missing data, removed data points and nature of distribution (Gaussian or non-Gaussian) of outliers, noise and clean data. These are major advantages over the existing linear fit methods. Since having a perfect linear relation between two variables in the real world is impossible, we used artificial data sets with extreme conditions to verify the method. The method detects the correct linear fit when the percentage of data agreeing with linear fit is less than 50%, and the deviation of data that do not agree with linear fit is very small, of the order of ±10−4%. The method results in incorrect detections only when numerical accuracy is insufficient in the calculation process.

Abstract
Bipolar disorder (BD) is a severe and highly heritable neuropsychiatric disorder with a lifetime prevalence of 1%. Molecular genetic studies have identified the first BD susceptibility genes. However, the disease pathways remain largely unknown. Accumulating evidence suggests that microRNAs, a class of small noncoding RNAs, contribute to basic mechanisms underlying brain development and plasticity, suggesting their possible involvement in the pathogenesis of several psychiatric disorders, including BD. In the present study, gene-based analyses were performed for all known autosomal microRNAs using the largest genome-wide association data set of BD to date (9747 patients and 14 278 controls). Associated and brain-expressed microRNAs were then investigated in target gene and pathway analyses. Functional analyses of miR-499 and miR-708 were performed in rat hippocampal neurons. Ninety-eight of the six hundred nine investigated microRNAs showed nominally significant P-values, suggesting that BD-associated microRNAs might be enriched within known microRNA loci. After correction for multiple testing, nine microRNAs showed a significant association with BD. The most promising were miR-499, miR-708 and miR-1908. Target gene and pathway analyses revealed 18 significant canonical pathways, including brain development and neuron projection. For miR-499, four Bonferroni-corrected significant target genes were identified, including the genome-wide risk gene for psychiatric disorder CACNB2. First results of functional analyses in rat hippocampal neurons neither revealed nor excluded a major contribution of miR-499 or miR-708 to dendritic spine morphogenesis. The present results suggest that research is warranted to elucidate the precise involvement of microRNAs and their downstream pathways in BD.

Abstract
OBJECTIVE The aim of the study was to summarize and evaluate the recent literature on treatment in psychiatric day clinics, and to assess the importance of such clinics in the current healthcare system. METHOD We conducted a systematic review of recent studies in order to compare the efficacy and cost effectiveness of day clinics in relation to in- and outpatient treatment. RESULTS The evidence is still sparse and inconclusive. CONCLUSION Psychiatric day clinics act as a link between inpatient and outpatient treatment in community mental healthcare. However, evidence in support of the efficacy and cost-effectiveness of day clinics is still sparse.

Abstract
BACKGROUND The "Psychiatrie-Enquete" (German Report on the State of Psychiatry) is 40 years old this year. It has always been inspirational; also internationally. OBJECTIVE Which innovative elements of community mental health services can be found in an international perspective? MATERIALS AND METHODS Narrative review. RESULTS Community mental health care is a lively field with much research and innovative practice. With assertive community treatment (ACT) and home treatment (HT), internationally well-evaluated forms of community mental health care are available. CONCLUSION Recovery-based and peer-to-peer approaches hold promise for the future. In terms of mid- and long-term perspectives, an increase in patient-centering via individualization of mental health care and a better implementation of community mental health interventions would be desirable in Germany.
