Abstract
Deficits in the ability to encode small differences in contrast between adjacent parts of an image (contrast sensitivity) are well documented in schizophrenic patients. In the present study, we sought to determine whether contrast sensitivity deficits reported in schizophrenic patients are also evident in those who exhibit high schizotypy scores in a typical (i.e., non-schizophrenic) population. Using the O-Life Questionnaire, we determined the effects of schizotypy on spatial (0.5, 2 and 8 c/deg) and spatiotemporal (0.5 and 8 c/deg at 0.5 and 8 Hz) contrast sensitivity in 73 young (18-26 years), majority female (n = 68) participants. We found differences in contrast sensitivity that were spatial, spatiotemporal and O-Life subscale specific. Spatial contrast sensitivity was significantly lower in high, compared to low schizotypes at low spatial frequencies (0.5 c/deg) in those who scored highly on the Unusual Experiences and Cognitive Disorganisation O-Life subscales. For moving stimuli, individuals with high scores on the Unusual Experiences subscale exhibited lower spatiotemporal contrast sensitivity for 0.5 and 8 c/deg patterns drifting at 8 Hz. Although the effects reported here were relatively small, this is the first report of reduced contrast sensitivity in schizotypy.

Abstract
Understanding the normal temporal variation of serum molecules is a critical factor for identifying useful candidate biomarkers for the diagnosis and prognosis of chronic disease. Using small RNA sequencing in a longitudinal study of 66 women with no history of cancer, we determined the distribution and dynamics (via intraclass correlation coefficients, ICCs) of the miRNA profile over 3 time points sampled across 2-5 years in the course of the screening trial, UKCTOCS. We were able to define a subset of longitudinally stable miRNAs (ICC >0.75) that were individually discriminating of women who had no cancer over the study period. These miRNAs were dominated by those originating from the C14MC cluster that is subject to maternal imprinting. This assessment was not significantly affected by common confounders such as age, BMI or time to centrifugation nor alternative methods to data normalisation. Our analysis provides important benchmark data supporting the development of miRNA biomarkers for the impact of life-course exposure as well as diagnosis and prognostication of chronic disease.

Abstract
The present article is the third installment in a five-part series related to evidence-based medicine (EBM) provided by the European Society for Paediatric Urology Research Committee. It will present the different levels of evidence (i.e. systematic review, randomized controlled trial, cohort study) available to clinicians and researchers and describe the strengths of each study type. While EBM provides a valuable construct to aid in medical decision-making, it remains imperative that this information be interpreted and applied in the clinical context with a good dose of common sense.

Abstract
This manuscript is the fourth in a five part series related to evidence based medicine (EBM) provided by the European society of pediatric urology (ESPU) research committee. It will present a way to come to a quick and critical appraisal of available evidence on a specific topic: a CAT (critically appraised topic). The way how to write a cat is described for interventions to be compared to a control group, and for other, more generalized clinical questions. While systematic reviews provide a throughout overview of all evidence available, a CAT provides a shorter way to come to quick insights based on EBM.

Abstract
The present article is a second part related to evidence based medicine (EBM) in a series of five by the European society for paediatric urology (ESPU) research committee. It will present the different databases/search engines available to clinicians and researchers and describe strategies to focus the search to one's particular needs. Indeed, databases/search engines used and search strategy should vary according to the goal of the research. If the aim is to address a clinical problem, the search should allow to identify a small number of most pertinent articles (high specificity); if the search is for research purposes, instead, it should ensure no meaningful articles are overlooked (high sensitivity).

Abstract
BACKGROUND Tick-borne encephalitis (TBE) is a viral disease that can have a severe clinical course and considerable long-term morbidity. As no curative treatment exists, vaccination is the primary means of prevention. Long-term antibody seropersistence 2-5 years after the 3-dose primary immunization and 3-10 years after first booster was evaluated, as well as booster responses in children, adolescents and young adults. METHODS Subjects who participated in these phase 4 prospective, open-label follow-up studies received all vaccinations with FSME-IMMUN. After 3-dose primary immunization, subjects were followed for 2-5 years. Overall, 205 out of 358 subjects (57%) received the first booster and 179 of these subjects (87%) enrolled in a further 10-year follow-up. Antibody seropersistence was assessed annually. Subjects with a TBE antibody titer below a pre-specified cut-off at the yearly blood draw received a booster. Seropositivity rates and geometric mean fold rises (GMFRs) were assessed. RESULTS In children who received their 3-dose primary immunization between 1 and 15 years of age, the seropositivity rate 5 years after the 3rd dose was 84.9% by NT and 72.0% by ELISA. One month post-first booster, all subjects were seropositive by NT and 98.5% by ELISA. Response to first booster by GMFR ranged from 3.7 to 11.4. At 5 years post-first booster, seropositivity was 99.4% by NT and 97.5% by ELISA, and at 10 years, was 90.3% by NT and 87.7% by ELISA. Although seropositivity rates differed between age groups, all subjects (100%) who received a second booster responded with a robust increase of TBEV antibodies. DISCUSSION Long-lasting seropersistence of TBEV antibodies after the 3-dose primary immunization and first booster was demonstrated as well as a competent immune memory response in those who received a first or second booster at any time during the 15-year follow-up. Therefore, an extension of FSME-IMMUN booster interval up to 10 years after the 3-dose primary immunization seems warranted. ClinicalTrials.gov Identifier: NCT00894686.

Abstract
OBJECTIVE The aims of the study were to analyze the current European situation of specialist education and training within clinical neuropsychology, and the legal and professional status of clinical neuropsychologists in different European countries. METHOD An online survey was prepared in 2016 by a Task Force established by the European Federation of Psychological Associations, and representatives of 30 countries gave their responses. Response rate was 76%. RESULTS Only three countries were reported to regulate the title of clinical neuropsychologist as well as the education and practice of clinical neuropsychologists by law. The most common university degree required to practice clinical neuropsychology was the master's degree; a doctoral degree was required in two countries. The length of the specialist education after the master's degree varied between 12 and 60 months. In one third of the countries, no commonly agreed upon model for specialist education existed. A more systematic training model and a longer duration of training were associated with independence in the work of clinical neuropsychologists. CONCLUSIONS As legal regulation is mostly absent and training models differ, those actively practicing clinical neuropsychology in Europe have a very heterogeneous educational background and skill level. There is a need for a European standardization of specialist training in clinical neuropsychology. Guiding principles for establishing the common core requirements are presented.

Abstract
INTRODUCTION Urethral duplication is extremely rare in girls, with less than 40 cases reported so far. Most of them present as a prepubic sinus. Literature is scare regarding aetiology, classification and management in other forms. This study presents three cases of sagittal urethral duplication in girls presenting a main hypospadiac urethra and an accessory epispadiac urethra. PATIENTS AND METHODS Medical records were retrospectively reviewed of three girls with urethral duplication managed over a 30-year period at a single institution. Circumstances of diagnosis, management and outcomes were analysed. RESULTS The oldest case presented as a neonatal retrovesical mass with an accessory clitoral stream, whereas the two more recent cases presented with antenatal hydrocolpos and bilateral ureterohydronephrosis. Cases 1 and 3 had an incomplete duplication, while Case 2 had a complete form. In Case 3, the duplication was associated with a urogenital sinus and an anteriorly placed anus. Management involved resection of the epispadiac accessory urethra to achieve continence, with dilatation and/or mobilisation of the hypospadiac one. All girls are now aged >5 years old and are continent, and one is old enough to have normal menstruation. Renal function is normal in all. The summary table presents the schematic anatomical description as shown on micturating cystourethrogram and endoscopy, as well as the management for each patient. DISCUSSION Step-by-step management is necessary in urethral duplication. The neonatal emergency is to release the urinary tract compression by evacuating urinary retention or hydrocolpos. Later in infancy, decision has to be taken regarding the urethras. If the resection of the epispadiac accessory urethra seems acceptable to achieve continence, the attitude towards the hypospadiac channel is more controversial and should be individualised. Embryologic and aetiopathogenic pathways are still missing to uniformly characterise the malformation. CONCLUSION Paediatric urologists should remember that there is a wide spectrum of urethral duplication in girls, and that various presentations exist beside the more classic prepubic sinus.

Abstract
Emerging data suggest that expansion of a circulating population of atypical, cytotoxic CD4(+) T cells lacking costimulatory CD28 (CD4(+) CD28(null) cells) is associated with latent cytomegalovirus (CMV) infection. The purpose of the current study was to increase the understanding of the relevance of these cells in 100 unselected kidney transplant recipients followed prospectively for a median of 54 months. Multicolor flow cytometry of peripheral blood mononuclear cells before transplantation and serially posttransplantation was undertaken. CD4(+) CD28(null) cells were found predominantly in CMV-seropositive patients and expanded in the posttransplantation period. These cells were predominantly effector-memory phenotype and expressed markers of endothelial homing (CX3CR1) and cytotoxicity (NKG2D and perforin). Isolated CD4(+) CD27(-) CD28(null) cells proliferated in response to peripheral blood mononuclear cells previously exposed to CMV-derived (but not HLA-derived) antigens and following such priming incubation with glomerular endothelium resulted in signs of endothelial damage and apoptosis (release of fractalkine and von Willebrand factor; increased caspase 3 expression). This effect was mitigated by NKG2D-blocking antibody. Increased CD4(+) CD28(null) cell frequencies were associated with delayed graft function and lower estimated glomerular filtration rate at end follow-up. This study suggests an important role for this atypical cytotoxic CD4(+) CD28(null) cell subset in kidney transplantation and points to strategies that may minimize the impact on clinical outcomes.

Abstract
Introduction Despite excellent first year outcomes in kidney transplantation, there remain significant long-term complications related to new-onset diabetes after transplantation (NODAT). The purpose of this study was to validate the findings of previous investigations of candidate gene variants in patients undergoing a protocolised, contemporary immunosuppression regimen, using detailed serial biochemical testing to identify NODAT development. Methods One hundred twelve live and deceased donor renal transplant recipients were prospectively followed-up for NODAT onset, biochemical testing at days 7, 90, and 365 after transplantation. Sixty-eight patients were included after exclusion for non-white ethnicity and pre-transplant diabetes. Literature review to identify candidate gene variants was undertaken as described previously. Results Over 25% of patients developed NODAT. In an adjusted model for age, sex, BMI, and BMI change over 12 months, five out of the studied 37 single nucleotide polymorphisms (SNPs) were significantly associated with NODAT: rs16936667:PRDM14 OR 10.57;95% CI 1.8–63.0;p = 0.01, rs1801282:PPARG OR 8.5; 95% CI 1.4–52.7; p = 0.02, rs8192678:PPARGC1A OR 0.26; 95% CI 0.08–0.91; p = 0.03, rs2144908:HNF4A OR 7.0; 95% CI 1.1–45.0;p = 0.04 and rs2340721:ATF6 OR 0.21; 95%CI 0.04–1.0; p = 0.05. Conclusion This study represents a replication study of candidate SNPs associated with developing NODAT and implicates mTOR as the central regulator via altered insulin sensitivity, pancreatic β cell, and mitochondrial survival and dysfunction as evidenced by the five SNPs. General significance Highlights the importance of careful biochemical phenotyping with oral glucose tolerance tests to diagnose NODAT in reducing time to diagnosis and missed cases. This alters potential genotype:phenotype association. The replication study generates the hypothesis that mTOR signalling pathway may be involved in NODAT development.

Abstract
Recent cross-sectional studies suggest an important role for transitional B lymphocytes (CD19 + CD24hiCD38hi) in promoting transplant tolerance, and protecting from late antibody-mediated rejection (ABMR). However, prospective studies are lacking. This study enrolled 73 de novo transplant recipients, and collected serial clinical, immunological and biochemical information over 48 ± 6 months. Cell phenotyping was conducted immediately prior to transplantation, and then on five occasions during the first year posttransplantation. When modeled as a time-dependent covariate, transitional B cell frequencies (but not total B cells or "regulatory" T cells) were associated with protection from acute rejection (any Banff grade; HR: 0.60; 95% CI: 0.37-0.95; p = 0.03). No association between transitional B cell proportions and either de novo donor-specific or nondonor-specific antibody (dnDSA; dnNDSA) formation was evident, although preserved transitional B cell proportions were associated with reduced rejection rates in those patients developing dnDSA. Three episodes of ABMR occurred, all in the context of nonadherence, and all associated with in vitro anti-HLA T cell responses in an ELISPOT assay (p = 0.008 versus antibody-positive patients not experiencing ABMR). This prospective study supports the potential relevance of transitional ("regulatory") B cells as a biomarker and therapeutic intervention in transplantation, and highlights relationships between humoral immunity, cellular immunity and nonadherence.

Abstract
INTRODUCTION Postnatal management of prenatally detected hydronephrosis remains controversial. It has been suggested that cortical transit time (CTT) could successfully predict deterioration in children with pelvi-ureteric junction (PUJ) obstruction. We decided to conduct a retrospective study in our hydronephrosis population to evaluate whether initial CTT was significantly correlated with the need for surgery. PATIENTS AND METHOD We reviewed the charts of all our patients managed for significant PUJ obstruction (>12 mm) between 2007 and 2010 and determined CTT retrospectively, on the first diuretic scan of each of these patients. We then determined the relationship between initial CTT and the need for surgery. RESULTS We identified 37 patients with hydronephrosis (pelvic size >12 mm) of which 26 were diagnosed prenatally. Out of 22 patients with an initial abnormal CTT, 20 underwent surgery. Out of 15 children with a normal initial CTT, 4 underwent surgery (OR 27.5 (IC95%: 4.3-174.9)). CONCLUSION Initial CTT could be a reliable prognostic factor for future evolution of renal function in children with hydronephrosis. CTT is easy to determine on diuretic renal scan. A prospective trial is being devised to confirm what role it could have in the management of children with hydronephrosis.
