Abstract
Introduction: To evaluate, if targeted strip biopsies decrease trauma/pain perception while maintaining diagnostic accuracy in patients with the diagnosis of high-grade squamous intraepithelial lesions of the uterine cervix. Patients and Methods: Between July 1st and December 31st 2014 we performed colposcopically directed strip biopsies in 102 patients with colposcopic suspicion of high-grade squamous intraepithelial lesions of the uterine cervix. We used a 3 mm curette for harvesting tissue samples under VITOM® videocolposcopy. So far, 60 patients underwent additional loop excision. Histologic examination of strip biopsies and loop specimens included routine hematoxylin and eosin staining as well as immunohistochemical staining for p16, Ki 67 and stathmin-1. Results: 55 patients (53 %), were histologically diagnosed with cervical intraepithelial neoplasia grade 3 on strip biopsies. Adenocarcinoma in situ was diagnosed in 2 patients (2 %), cervical intraepithelial neoplasia grade 2 in 35 patients (34 %), and cervical intraepithelial neoplasia grade 1 in 10 patients (10 %). The agreement between histologic results of strip biopsy and loop specimen was highly significant: In all 60 strip biopsies diagnosed with high-grade squamous intraepithelial lesions this diagnosis was confirmed histologically during follow-up loop specimen excision (high-grade squamous intraepithelial lesions in 58 patients, invasive disease in 2 patients). The pain level experienced during strip biopsy was rated on average 0.25 on a scale from 0 to 10. No clinically significant bleeding was reported. Conclusion: Targeted strip biopsies with a 3 mm curette are a reliable procedure to diagnose high-grade squamous intraepithelial lesions of the uterine cervix and yield high patient satisfaction (Video 1).

Abstract
The aim of this study was to evaluate whether changing the interval from CIDR removal to timed artificial insemination (TAI) according to the diameter of the preovulatory follicle (POF) would improve pregnancy per AI in cows. In Study 1, a retrospective analysis of TAI experiments (n=96 cows) was performed to characterize the time of ovulation according to the diameter of the dominant follicle. It was observed that cows with a larger POF had ovulations earlier than cows with smaller POF, according to the equation: y=0.72x(2)-26.74x+264.54 (R(2)=0.63; P<0.001). In Study 2, lactating Nelore cows (n=412) were subjected to an EB-CIDR based TAI protocol. On the morning of Day 10 (time of TAI), cows were randomized into Control (n=209) and Block (n=203) groups; (1) Cows in the Control Group were TAI 48 h after CIDR removal (08:00 am on Day 10), and; (2) Cows in the block group were inseminated once at one of the following time points, according to the diameter of the POF on Day 10: B0 (POF≥15mm, TAI 0 h after convetional TAI), B1 (POF 13-14.9 mm, TAI 6h later), B2 (POF 10.1-12.9 mm, TAI 24h later) and B3 (POF≤10mm, TAI 30 h later). The cows of the Block Group had greater pregnancy rates per AI than the Control Group (129/203, 63.5% when compared with 102/209, 48.8%, respectively; P<0.01). In conclusion, results of the present study demonstrate that adjusting the timing of TAI according to the diameter of the POF can be an effective practice for improving fertility of cows in TAI protocols.

Abstract
Rhabdomyosarcoma (RMS) is the most common pediatric soft tissue sarcoma. In children, the 2 major RMS subtypes are alveolar and embryonal RMS. Aberrant Hedgehog/Patched1 (Hh/Ptch) signaling is a hallmark of embryonal RMS. We demonstrate that mice carrying a Ptch mutation in mesodermal Delta1-expressing cells develop embryonal-like RMS at a similar rate as mice harboring a Ptch mutation in the germline or the brachury-expressing mesoderm. The tumor incidence decreases dramatically when Ptch is mutated in Myf5- or Pax3-expressing cells. No RMS develop from Myogenin/Mef2c-expressing cells. This suggests that Hh/Ptch-associated RMS are derived from Delta1-positive, Myf5-negative, Myogenin-negative and Pax3-negative mesodermal progenitors that can undergo myogenic differentiation but lack stable lineage commitment. Additional preliminary genetic data and data on mesodermal progenitors further imply an interplay of Hh/Ptch and Delta/Notch signaling activity during RMS initiation. In contrast, Wnt signals supposedly suppress RMS formation because RMS multiplicity decreases after inactivation of the Wnt-inhibitor Wif1. Finally, our results strongly suggest that the tumor-initiating event determines the lineage of RMS origin.

Abstract
BACKGROUND The influence of physical strain on the esophageal motility has already been examined in a number of studies. It was found that high physical strain compromises the sufficient contractility of the esophagus. However, it needs more examinations to verify these findings. METHODS To validate these results healthy volunteers were examined using gas-perfusion manometrie. Bicycle ergometry was performed to generate an exactly defined physical exercise. After a pilot study, the changing of the contraction amplitude was determined as the main variable to evaluate the esophageal motility, and the sample size was calculated. Eight subjects without esophageal diseases or symptoms were examined by simultaneous gas-perfusion esophageal manometry and bicycle ergometry. KEY RESULTS The results showed that high physical strain during bicycle ergometry can induce a significant decrease of the contraction amplitude (α = 5%, β = 10%). The 95% confidence interval of the quotient of contraction amplitude at rest and under physical strain is (1.074; 1.576). This effect is more pronounced in liquid acts of swallowing than in dry and is also more obvious at the middle measuring point (7.8 cm above the lower esophageal sphincter) than at the distal and proximal point (2.8 and 12.8 cm). Furthermore, a decreasing tendency of the contraction duration could be found. CONCLUSIONS & INTERFERENCES Gas-perfusion manometry is an inexpensive examination method, which enables the evaluation of the esophageal motility in moving test subjects under conditions of physical strain. It could be proved that physical strain negatively influences the esophageal motility by a decrease of the contraction amplitude.

Abstract
Our mixed methods (narrative interviews; group discussions; quantitative online survey) study examines the motivation of physicians in training as specialists in general practice to open their own practice. In addition, we wondered how motivations change during the vocational training. In a synchronic perspective motivations are highly differentiated on the one hand, on the other hand they are clearly gender-specific. In a diachronic perspective, the decision for or against their own GP surgery is uncertain for a long time during vocational training.

Abstract
Aim: This mixed-methods cross-sectional study examined the cooperation between nursing home staff and physicians in Bavarian nursing homes in order to understand which organisational and communication measures are resulting in satisfying teamwork among professional groups in nursing homes. Methods: In 3 interview rounds nursing home staff, general practitioners, medical specialists, dentists, nursing home residents, and relatives in 52 nursing homes were interviewed using a questionnaire that was enhanced after every round. Additionally, focus group interviews have been performed in 2 nursing homes. Results: 443 persons involved in patient care, 50 residents and 47 relatives participated in the structured interviews. 22 persons attended the focus group interviews. 65% of the nursing homes required regular visits of general practitioners and 36% or, respectively, 27% required regular or on demand visits of specialists. 47% of the nursing home staff that was asked about this issue stated that it would make their work easier if only a small number of physicians were in charge of their institution. Measures for improvement of medical care in nursing homes most frequently suggested by interview partners responsible for patient care were: better communication (9%), better remuneration of physicians' nursing home visits (7%, nurses and physicians) and less bureaucracy and regular physicians' visits (5% in each question). Conclusion: Because of the composition of our study sample it cannot be assumed that the results are representative for all Bavarian nursing homes. Confidence in one another, low number of persons in charge, binding agreements and regular physicians' nursing home visits are essential for a successful cooperation between providing physicians and nursing home staff.

Abstract
BACKGROUND In the 1960s, Peter Safar et al. postulated the benefit of postcardiac arrest hypothermia after successful cardiopulmonary resuscitation (CPR). However, therapeutic hypothermia postCPR did not become a standard procedure until the first few years of the new millennium. Various noninvasive and invasive cooling methods are available. Generally, more invasive cooling methods are more effective-but also tend to involve more complications. Furthermore, invasive measures need more time and thus may be instituted late in the postCPR process, delaying the cooling efforts in the initial phase. There is ongoing controversy about when best to commence cooling. CURRENT SITUATION Recent studies of initial out-of-hospital cooling did not show any benefit for the patients compared to starting cooling in the hospital. The exact target temperature is the subject of multiple ongoing discussions. A recent study showed no disadvantage of cooling to 36 ℃ compared to 33 ℃, which is in the widely accepted standard target temperature range of 32-34 ℃. Nevertheless, cooling to 32-34 ℃ according to the 2010 guidelines is still the accepted standard procedure unless and until new studies generate more evidence. The European Resuscitation Council has given advance notice of a statement on the optimal target temperature in the near future. Finally, large registry studies have demonstrated the benefit of combining postCPR hypothermia with early percutaneous cardiac interventions (PCI) in acute coronary syndromes, which are often a cause of cardiac arrest. OUTLOOK Transport of patients after CPR to specialized postcardiac arrest centres with the possibility of acute PCI and cooling, comparable to the transfer of multiple trauma patients to trauma centres, may be beneficial.

Abstract
BACKGROUND The German hospital reimbursement system (G-DRG) is incomplete for endoscopic interventions and fails to differentiate between complex and simple procedures. This is caused by outdated methods of personnel-cost allocation. METHODS To establish an up-to-date service catalogue 50 hospitals made their anonymized expense-budget data available to the German-Society-of-Gastroenterology (DGVS). 2.499.900 patient-datasets (2011-2013) were used to classify operation-and-procedure codes (OPS) into procedure-tiers (e.g. colonoscopy with biopsy/colonoscopy with stent-insertion). An expert panel ranked these tiers according to complexity and assigned estimates of physician time. From June to November 2014 exact time tracking data for a total 38.288 individual procedures were collected in 119 hospitals to validate this service catalogue. RESULTS In this three-step process a catalogue of 97 procedure-tiers was established that covers 99% of endoscopic interventions performed in German hospitals and assigned validated mean personnel-costs using gastroscopy as standard. Previously, diagnostic colonoscopy had a relative personnel-cost value of 1.13 (compared to gastroscopy 1.0) and rose to 2.16, whereas diagnostic ERCP increased from 1.7 to 3.62, more appropriately reflecting complexity. Complex procedures previously not catalogued were now included (e.g. gastric endoscopic submucosal dissection: 16.74). DISCUSSION This novel service catalogue for GI-endoscopy almost completely covers all endoscopic procedures performed in German hospitals and assigns relative personnel-cost values based on actual physician time logs. It is to be included in the national coding recommendation and should replace all prior inventories for cost distribution. The catalogue will contribute to a more objective cost allocation and hospital reimbursement - at least until time tracking for endoscopy becomes mandatory.

Abstract
We utilized a sample of 299 adult females aged between 19 and 86 years, carrying fragile X mental retardation (FMR1) alleles with small CCG expansions ranging from 50 to 141 repeats to analyse the relationships between psychological symptoms as assessed by the Symptom Checklist-90-Revised (SCL-90-R) and the size of the CGG repeat in the FMR1 gene. There were highly significant (negative) correlations between the size of the CGG repeat and a great majority of SCL-90-R subscale scores and all the global indices, suggesting that carriers of premutations in the mid-size CGG repeat range may be at greatest risk for the development of psychiatric disorder.

Abstract
The aim of this study was to determine the effect of prepartum rbST injection on the metabolic profile of pregnant ewes induced to subclinical ketosis, as well as the metabolism until seven days of life and weight gain until seven weeks of life of the lambs. Twenty seven pregnant ewes of the pantaneiro genetic group were used, divided into two groups: rbST group (n = 14) and control group (n = 13). The rbST group received two applications of 1 mg/kg of rbST, at 97 and 111 days gestation, while the control group received placebo injections. There were significant differences between groups in levels of GGT in the ketosis post induction period and BHB concentrations in the postpartum period. Concentrations of glucose, urea, phosphorus, albumin, cholesterol, AST, NEFA and insulin were not different between dams from the two groups in different periods of the study (P>0.05). There was an effect of rbST on body weight observed already at fourteen days of life (P<0.0001), there was an increase in serum phosphorus levels at birth of lambs (P=0.0014), and albumin at seven days of life (P = 0.0014) of the lambs, with no difference between groups for the other metabolites. Therefore, the use of rbST was effective in increasing the weight of the lambs until the seventh week of life. In addition, rbST treatment had positive effects on the dam metabolism with reduction of liver overload, as indicated by decreased GGT after ketosis induction and decreased BHB at the postpartum period.

Abstract
Anophthalmia/microphthalmia (A/M) is a genetically heterogeneous birth defect for which the etiology is unknown in more than 50% of patients. We used exome sequencing with the ACE Exome(TM) (Personalis, Inc; 18 cases) and UCSF Genomics Core (21 cases) to sequence 28 patients with A/M and four patients with varied developmental eye defects. In the 28 patients with A/M, we identified de novo mutations in three patients (OTX2, p.(Gln91His), RARB, p.Arg387Cys and GDF6, p.Ala249Glu) and inherited mutations in STRA6 in two patients. In patients with developmental eye defects, a female with cataracts and cardiomyopathy had a de novo COL4A1 mutation, p.(Gly773Arg), expanding the phenotype associated with COL4A1 to include cardiomyopathy. A male with a chorioretinal defect, microcephaly, seizures and sensorineural deafness had two PNPT1 mutations, p.(Ala507Ser) and c.401-1G>A, and we describe eye defects associated with this gene for the first time. Exome sequencing was efficient for identifying mutations in pathogenic genes for which there is no clinical testing available and for identifying cases that expand phenotypic spectra, such as the PNPT1 and COL4A1-associated disorders described here.

Abstract
In the 19th century, synthetic chemistry discovered completely new chemical entities for medicinal use, which dramatically enriched the therapeutic armamentarium. However, no information was available regarding the safety of these new drugs, which were unrelated to most of the medicinal agents formerly known. Therefore, the question arises, if and how far, considerations regarding the relationship between benefit and risks were made. In this study, chloroform, phenazone (antipyrine) and sulfonal, were investigated as examples for drugs newly introduced in the 19th century. The results revealed that these drugs were provided by the manufacturer, tested by the physicians in a multicentre pattern and side effects were published in the medical literature soon after. Within a few years, several hundred cases were reported but the data were rarely summarized statistically. Therefore, physicians needed to stay updated with the medical literature because neither systematic industrial research nor regulatory authorities existed. The number of case reports within the first years were sufficient to detect common (> 1/100 to < 1/10) side effects but rare events were also reported. An extraordinary example is the drug-induced toxic epidermal necrolysis, which is commonly known as the Lyell syndrome or its less severe form, the Stevens-Johnson syndrome. This reaction has been clearly described by Baruch Spitz (1854-1932) as a side effect of antipyrine in 1887, several decades before Stevens, Johnson and particularly Lyell.

Abstract
The aim of the memorandum on the development of health services research (HSR) in Bavaria is to operationalise the global objectives of the State Working Group "Health Services Research" (LAGeV) and to collectively define future topics, specific implementation steps, methods as well as ways of working for the future course of the LAGeV. The LAGeV is an expert committee that integrates and links the competencies of different actors from science, politics and health care regarding HSR and facilitates their cooperation. The memorandum is based on an explorative survey among the LAGeV members, which identified the status quo of health services research in Bavaria, potential for development, important constraints, promoting factors, specific recommendations as well as future topics for the further development of HSR in Bavaria. From the perspective of the LAGeV members, the 12 most important future topics are: 1) Interface and networking research, 2) Innovative health care concepts, 3) Health care for multimorbid patients, 4)Health care for chronically ill patients, 5) Evaluation of innovations, processes and technologies, 6) Patient orientation and user focus, 7) Social and regional inequalities in health care, 8) Health care for mentally ill patients, 9) Indicators of health care quality, 10) Regional needs planning, 11) Practical effectiveness of HSR and 12) Scientific use of routine data. Potential for development of HSR in Bavaria lies a) in the promotion of networking and sustainable structures, b) the establishment of an HSR information platform that bundles information and results in regard to current topics and aims to facilitate cooperation as well as c) in the initiation of measures and projects. The latter ought to pinpoint health care challenges and make recommendations regarding the improvement of health care and its quality. The cooperation and networking structures that were established with the LAGeV should be continuously expanded and be used to work on priority topics in order to achieve the global objectives of the LAGeV.

Abstract
BACKGROUND The aim of this review is to provide an overview about health services research in Bavarian primary care. METHODS The academic development of general practice and the associated health services research is described within this narrative -review. RESULTS Health services research is a heterogeneous field which might be best described for primary care as "research along the last mile of the health care System". Various elements are evolving in Bavarian primary care research, like investigation of diagnostic issues, impact of psychosomatic co-morbidity on patient management and maintenance of medical services in rural areas. Strategies to analyse and interpret routine data are established in cooperation with the Bavarian Association of Statutory Health Insurance Physicians (KVB) which alleviates understanding of health care in Bavaria. CONCLUSION The development of health services research in primary care is accompanied by the evolution of general practice as an academic discipline. Health services research should be strengthened to improve understanding and management of health care resource use. The presence of oversupply in large attractive cities combined with a shortage of physicians in rural areas is a specific challenge for health care planning in Bavaria. This is of importance for medical care of the ageing population; and needs to be addressed with reference to the shortage of general practitioners in rural areas.

Abstract
We report a case of discordant phenotypic sex in monozygotic twins mosaic 47,XXY/46,XX: monozygotic heterokaryotypic twins. The twins presented with cognitive and comprehension delay, behavioural and language disorders, all symptoms frequently reported in Klinefelter syndrome. Molecular zygosity analysis with several markers confirmed that the twins are in effect monozygotic (MZ). Array comparative genomic hybridization found no evidence for the implication of copy number variation in the phenotypes. Ultrasound scans of the reproductive organs revealed no abnormalities. Endocrine tests showed a low testosterone level in Twin 1 (male phenotype) and a low gonadotrophin level in Twin 2 (female phenotype) which, combined with the results from ultrasound examination, provided useful information for potentially predicting the future fertility potential of the twins. Blood karyotypes revealed the presence of a normal 46,XX cell line and an aneuploïd 47,XXY cell line in both patients. Examination of the chromosome constitutions of various tissues such as blood, buccal smear and urinary sediment not surprisingly showed different proportions for the 46,XX and 47,XXY cell lines, which most likely explains the discordant phenotypic sex and mild Klinefelter features. The most plausible underlying biological mechanism is a post-zygotic loss of the Y chromosome in an initially 47,XXY zygote. This would result in an embryo with both 46,XX and 47,XXY cells lines which could subsequently divide into two monozygotic embryos through a twinning process. The two cell lines would then be distributed differently between tissues which could result in phenotypic discordances in the twins. These observations emphasize the importance of regular paediatric evaluations to determine the optimal timing for fertility preservation measures and to detect new Klinefelter features which could appear throughout childhood in the two subjects.

Abstract
In 2007, a multifaceted syndrome, associated with anti-NMDA receptor autoantibodies (NMDAR-AB) of immunoglobulin-G isotype, has been described, which variably consists of psychosis, epilepsy, cognitive decline and extrapyramidal symptoms. Prevalence and significance of NMDAR-AB in complex neuropsychiatric disease versus health, however, have remained unclear. We tested sera of 2817 subjects (1325 healthy, 1081 schizophrenic, 263 Parkinson and 148 affective-disorder subjects) for presence of NMDAR-AB, conducted a genome-wide genetic association study, comparing AB carriers versus non-carriers, and assessed their influenza AB status. For mechanistic insight and documentation of AB functionality, in vivo experiments involving mice with deficient blood-brain barrier (ApoE(-/-)) and in vitro endocytosis assays in primary cortical neurons were performed. In 10.5% of subjects, NMDAR-AB (NR1 subunit) of any immunoglobulin isotype were detected, with no difference in seroprevalence, titer or in vitro functionality between patients and healthy controls. Administration of extracted human serum to mice influenced basal and MK-801-induced activity in the open field only in ApoE(-/-) mice injected with NMDAR-AB-positive serum but not in respective controls. Seropositive schizophrenic patients with a history of neurotrauma or birth complications, indicating an at least temporarily compromised blood-brain barrier, had more neurological abnormalities than seronegative patients with comparable history. A common genetic variant (rs524991, P=6.15E-08) as well as past influenza A (P=0.024) or B (P=0.006) infection were identified as predisposing factors for NMDAR-AB seropositivity. The >10% overall seroprevalence of NMDAR-AB of both healthy individuals and patients is unexpectedly high. Clinical significance, however, apparently depends on association with past or present perturbations of blood-brain barrier function.

Abstract
OBJECTIVE The aim of this study was to identify individual therapy goals (ITGs) of children and adolescents with ADHD and their primary caregivers. METHODS Within the evaluation of the selective contract for children and adolescents with ADHD in Bremerhaven, Germany, ITGs of 42 study participants (aged 8-17) and their primary caregivers were collected with the psychotherapy basis documentation for children and adolescents (Psy-BaDo-KJ). ITGs were analysed following the classification of categories for individual therapy goals (KITZ) and their modification for children and adolescents. Analysis focused on the most frequently named ITGs and the agreement of patients and primary caregivers ITGs on the individual level. RESULTS 235 ITGs were named. The greatest proportion of ADHD patients and their caregivers (47%) focused on interactional, psychosocial conflicts. In 19% of the cases (n=8) patients and their caregivers had the same main goal. 38% of patients and of caregivers (n=16) named the other ones main goal in one of his/her ITGs as well. CONCLUSIONS ADHD patients and their primary caregivers both pursue ITGs related to ADHD symptoms. Few ITGs address medication related aspects. In case of differences in the ITGs of a patient and his/her primary caregivers, therapists should check whether differing ITGs address the same problem from different perspectives.

Abstract
OBJECTIVES Current population-based surveys in Europe on the prevalence of dietary supplement (DS) use in older individuals are scarce. The aim of the present study was to investigate patterns, prevalence and determinants of non-herbal DS use in aged subjects. Furthermore, the intake amounts of vitamins and minerals from supplements were assessed. DESIGN Cross-sectional. SETTING Data on supplement use were available from an age- and sex-stratified random sample of the German population-based KORA (Cooperative Health Research in the Region of Augsburg)-Age study. PARTICIPANTS 1,079 persons who were born in or before the year 1943. MEASUREMENTS Use of dietary supplements and medications during the last seven days was recorded in a face-to-face interview in 2009. Participants were asked to bring all packages of ingested preparations to the study center. Not only vitamin/mineral supplements, but also non-vitamin non-mineral non-herbal supplements and drugs containing vitamins and minerals were coded as DS. RESULTS The age-standardized prevalence of DS intake was 54.3% in women and 33.8% in men, respectively. The most commonly supplemented mineral and vitamin, respectively, was magnesium (31.9%) and vitamin D (21.5%) in women and magnesium (18.0%) and vitamin E (12.0%) in men. The highest intakes, compared to the German Dietary Reference Intakes, were reported for biotin, vitamin B6 and B1. Excessive intakes (equal or above the European Tolerable Upper Intake Levels (UL)) were observed especially for magnesium and vitamin E. 20.2% of the women and 32.5% of the men who took magnesium supplements regularly exceeded the UL for magnesium. In case of vitamin E this was true for 8.0% of the women and 13.6% of the men. Determinants of DS use were sex, education, smoking, physical activity, neurological diseases, and stroke. CONCLUSION A high proportion of the general population aged 65 years and older in Southern Germany uses DS, especially supplements containing vitamins/minerals. The supplementation of vitamin D can be regarded as favorable in this age group, whereas the excessive intakes of vitamin E might be a cause of concern.

Abstract
Mesenchymal stromal cells (MSCs) are multipotent cells, which exhibit broad immunosuppressive activities. Moreover, they may be administered irrespectively of human leukocyte antigen (HLA) compatibility, without inducing life-threatening immunological reactions, as they express no HLA class II and limited HLA class I antigens under resting conditions. These characteristics have made MSC an appealing candidate for cell therapy after hematopoietic stem cell transplantation (HSCT), for example, for treatment of graft-versus-host disease (GvHD) or for graft rejection prevention/treatment in allogeneic HSCT recipients. Unfortunately, information regarding the effect of MSC infusion on the host response to infectious agents is scarce, and study results on infectious complications in patients receiving MSC are conflicting. The present review focuses on the available data from in vitro studies and animal models regarding the interaction of MSC with bacterial, viral and fungal pathogens. In a clinical part, we present the current information on infectious complications in allogeneic HSCT recipients who had received MSCs as prophylaxis or treatment of GvHD disease.

Abstract
We utilized a sample of 299 adult females aged between 19 and 86 years, carrying fragile X mental retardation (FMR1) alleles with small CCG expansions ranging from 50 to 141 repeats to analyse the relationships between psychological symptoms as assessed by the Symptom Checklist-90-Revised (SCL-90-R) and the size of the CGG repeat in the FMR1 gene. There were highly significant (negative) correlations between the size of the CGG repeat and a great majority of SCL-90-R subscale scores and all the global indices, suggesting that carriers of premutations in the mid-size CGG repeat range may be at greatest risk for the development of psychiatric disorder.

Abstract
INTRODUCTION The aim of this study was to evaluate the current quality of care in newly diagnosed bladder cancer patients in a regional representative sample of German urologists. MATERIAL AND METHODS Using a standardized questionnaire clinical and pathological data from over 400 patients with newly diagnosed urothelial carcinoma of the bladder (UCB) between January and December 2010 were collected from urology health care practitioners in northern Germany. As diagnostic and therapeutic decisions were not influenced by a specific protocol these findings represent current regional practice patterns. RESULTS Complete data of 359 patients were available for analysis. The median patient age at diagnosis was 72 years (range 29-98 years) with a male:female ratio of 3:1. The main reasons for transurethral resection of the bladder (TURB) were microhematuria (45.4 %), conspicuous ultrasound findings (12.8 %) and gross hematuria (11.7 %). Using photodynamic diagnosis (PDD) TURB was performed in 78 patients (21.7 %). The results of histopathology showed papillary urothelial neoplasm of low malignant potential (PUNLMP) in 8 patients (2.2 %), pTa in 202 (56.3 %), pTis in 7 (1.9 %), pT1 in 88 (24.5 %) and ≥pT2 bladder cancer in 54 (15 %) patients. Multiple tumors were recorded in 107 patients (29.8 %). A repeat TURB was performed in 130 patients (36.8 %) in a median of 45 days and residual tumor tissue was found in 79 of these patients (60.8 %). Immediate postoperative instillation chemotherapy was performed in 152 patients (42.3 %) and adjuvant intravesical maintenance therapy was performed in 142 patients (39.6 %, mitomycin 29.2 % vs. BCG 10.4 %). Patients treated with repeat TURB or adjuvant instillation therapy were more likely to have higher tumor stages and grades (p-values< 0.001). Overall 25 patients (7.7 %) experienced disease recurrence within 3 months. Lower tumor stage and grade, performance of repeat TURB and administration of adjuvant intravesical therapy were associated with reduced early disease recurrence (p-values ≤ 0.009). CONCLUSIONS The current study presents contemporary findings and practice patterns in patients with newly diagnosed bladder cancer. Interestingly, the rates of immediate postoperative instillation chemotherapy and maintenance intravesical therapy were lower than expected. Utilization of PDD-TURB is still underrepresented. Remarkable is the high number of patients with residual tumor in the repeat TURB. Differences in patient counselling, hospital practice standards and compliance factors most likely contribute to variations in guideline adherence.

Abstract
As a result of the CD28 superagonist biotherapeutic monoclonal antibody (TGN 1412) "cytokine storm" incident, cytokine release assays (CRA) have become hazard identification and prospective risk assessment tools for screening novel biotherapeutics directed against targets having a potential risk for eliciting adverse pro-inflammatory clinical infusion reactions. Different laboratories may have different strategies, assay formats, and approaches to the reporting, interpretation, and use of data for either decision making or risk assessment. Additionally, many independent contract research organizations (CROs), academic and government laboratories are involved in some aspect of CRA work. As a result, while some pharmaceutical companies are providing CRA data as part of the regulatory submissions when necessary, technical and regulatory practices are still evolving to provide data predictive of cytokine release in humans and that are relevant to safety. This manuscript provides an overview of different approaches employed by the pharmaceutical industry and CROs, for the use and application of CRA based upon a survey and post survey follow up conducted by ILSI-Health and Environmental Sciences Institute (HESI) Immunotoxicology Committee CRA Working Group. Also discussed is ongoing research in the academic sector, the regulatory environment, current limitations of the assays, and future directions and recommendations for cytokine release assays.

Abstract
Growth, photo- and gravitropism of sporangiophores of the zygomycete Phycomyces blakesleeanus occur within the apical growing zone, a cylindrical structure (diameter about 100 μm) that reaches about 1.5-2.5 mm below the tip and has growth rates up to 50 μm·min(-1) . To better understand morphogenesis and growth of the giant aerial hypha, we investigated with confocal microscopy and inhibitors the actin cytoskeleton and by in-vivo particle tracking the associated organelle movement. We found stage-1 sporangiophores (without sporangium) possess an actin cytoskeleton with polar zonation. (i) In the apex, abundant microfilaments without preferential orientation entangled numerous nuclei as well as a conspicious complex of some 200 lipid globules. Microfilament patches (≈ 1.6-μm diameter) are clustered in the tip and were found in the apical cortex, whereas short, curved microfilament bundles (≈ 2.3-μm long) prevailed in the subapex. (ii) In a transition zone downwards to the shaft, the microfilaments rearranged into a dense mat of longitudinal microfilaments that was parallel close to the periphery but more random towards the cell centre. Numerous microfilament patches were found near the cortex (≈ 10/100 μm(2) ); their number decreased rapidly in the subcortex. In contrast, the short, curved microfilament bundles were found only in the subcortex. (iii) The basal shaft segment of the sporangiophore (with central vacuole) exhibited bidirectional particle movement over long distances (velocity ≈ 2 μm·s(-1) ) along massive longitudinal, subcortical microfilament cables. The zonation of the cytoskeleton density correlated well with the local growth rates at the tip of the sporangiophore, and appears thus as a structural prerequisite for growth and bending.
