Abstract
Attention Deficit Disorder with or without Hyperactivity (ADHD is a neurodevelopmental disorder which affects the day-to-day functioning of children and adults with this condition. Pharmacological treatment can reduce the symptoms associated with ADHD, but it has some limitations. The objective of this symposium is to determine the effects of non-pharmacological approaches on ADHD symptoms. Results indicate that the following intervention are promising approaches: cognitive behavioral therapy (CBT), mindfulness-based interventions (MBI), yoga, cognitive and metacognitive intervention, neurofeedback and parental training programs. Current research advocates multimodal approaches in conjunction with school or work accommodations integrating innovative technologies.

Abstract
Parental burnout (PB) is a chronic stress-related condition resulting from long-lasting exposure to overwhelming parenting stress. Previous studies showing the seriousness of this condition stressed the urgent need to provide researchers and practitioners with effective assessment tools. Validated PB measures are the Parental Burnout Inventory (PBI) and the Parental Burnout Assessment (PBA). The good psychometric properties of these instruments have been replicated across different samples and countries, but thresholds for identifying impairing PB levels (i.e., cutoff scores) have not yet been established. The present study aims to fill this gap by adopting a multi-informant and multimethod approach to a sample of 192 burned-out and control parents. PBI and PBA cutoffs were derived from the combination of several PB indicators, based on a preregistered analysis strategy. Results identified a score of 74.6 (95% confidence interval (CI) = [69.48-79.68]) for the PBI and 86.3 (95% CI = [79.49-93.03]) for the PBA as indicators of the most severe PB levels.

Abstract
Parental burnout refers to loss of energy and pleasure in the parental role. It is predictive of psychopathological outcomes in parents and dysfunctional parenting behaviors. Support of parental duties is central to alleviation of parental burden and prevention of burnout. Coparenting is the concept related to interparental mutual support in rearing a child. However, the links between coparenting and parental burnout have yet to be assessed. We thus aimed in this study to assess which dimensions of coparenting are linked with parental burnout. A total of 306 participants from the French-speaking part of Switzerland (120 fathers, 186 mothers) completed online questionnaires about parental burnout, their coparental relationship, and sociodemographic characteristics. We performed hierarchical regressions, entering sociodemographic characteristics in a first block and coparenting dimensions in a second block. Results showed that (i) a higher number of children and having younger children are linked to higher burnout; (ii) coparenting exposure to conflict is related to higher burnout, whereas endorsement of the partner's parenting is related to lower burnout; and (iii) no interaction effect occurs between sociodemographic characteristics and coparenting variables. Coparenting thus significantly contributes to the occurrence of burnout syndrome. Working on the coparental relationship preventively in parental educational programs or at a relational systemic level in therapy may help prevent burnout. Treating one parent only may not be sufficient to alleviate burnout, as negative coparenting could counter the effect of individual therapy.

Abstract
Children with attentional-deficit/hyperactivity disorder (ADHD) have impairments in working memory (WM) functioning. Impaired orienting of visual attention during encoding and/or maintenance is hypothesized as the cause of poor performance in visuospatial WM in 10-to-16-year-olds. We used a color-recognition task with valid location cues before encoding (pre-cues) and during maintenance (retro-cues). If ADHD children have an orienting deficit during these processing stages, they should not benefit from the cues. We observed strong pre- and retro-cueing benefits both for ADHD and typically developing controls, with no differences between the groups. This strengthens findings showing that ADHD is not characterized by deficits in orienting attention and provides evidence of retro-cue benefits in this population.

Abstract
The kinin receptors are classically involved in inflammation, pain and sepsis. The effects of the kinin B1 receptor agonist des-Arg9-bradykinin (DBK) and lipopolysaccharide (LPS) were investigated by comparing the membrane potential responses of aortic rings from transgenic rats overexpressing the kinin B1 receptor (B1R) in the endothelium (TGR(Tie2B1)) and Sprague Dawley (SD) rats. No difference in the resting membrane potential in the aorta’s smooth muscle from the transgenic and SD rats was observed. The aorta rings from SD rats hyperpolarized only to LPS but not to DBK, whereas the aorta rings from TGR(Tie2B1) responded by the administration of both drugs. DBK and LPS responses were inhibited by the B1 receptor antagonist R715 and by iberiotoxin in both cases. Thapsigargin induced a hyperpolarization in the smooth muscle of SD rats that was not reversed by R715, but was reversed by iberiotoxin and this hyperpolarization was further augmented by DBK administration. These results show that the model of overexpression of vascular B1 receptors in the TGR(Tie2B1) rats represent a good model to study the role of functional B1 receptors in the absence of any pathological stimulus. The data also show that KCa channels are the final mediators of the hyperpolarizing responses to DBK and LPS. In addition, we suggest an interaction between the B1R and TLR4, since the hyperpolarization induced by LPS could be abolished in the presence of R715.

Abstract
BackgroundDigital health applications (DHA) became indispensable patient companions accelerated by the current COVID pandemic [1]. In 2020, for the first time worldwide, a regulatory framework to reimburse DHA was established in Germany. To get listed as a DHA, preliminary evidence needs to be generated – next to fulfilling highest standards in quality and safety. The DHA ABATON RA consists of two parts; 1) digital shared-decision-making (SDM) including choosing an appropriate electronic patient reported outcome (ePRO) instrument and the respective ePRO target for the next visit, 2) remote patient monitoring and ePRO tracking by the patient. Hereby, ABATON RA supports a digitally guided Treat-to-Target (T2T) approach.ObjectivesThe objective of this study is to evaluate a potentially beneficial effect for the patient by using ABATON RA.MethodsThree-armed, partially blinded multicenter trial (RCT) including RA patients who regularly use a smartphone. Patients attend 3 visits, 3 months apart (T0, T3, T6), with one follow-up visit (T9). Intervention group (IG): Patients use ABATON RA. Via SDM patients and rheumatologists choose a specific ePRO and respective treatment target for the next visit in three months, e.g. RAID ≤4. Control group (CG): Standard of care treatment (no DHA). Placebo group (PG): Usage of a placebo version of ABATON RA providing only Regensburger Insomnie Skala (RIS) and Epworth Sleepiness Scale (ESS) as ePROs. No SDM is conducted and ePRO results are not presented to HCP.ResultsThis interim analysis evaluated the first 38 patients that completed T3. IG: 13 patients (Av. age 55.9, 61.5% females); PG: 12 (Av. age 50.7, 66.7% females); CG: 13 (Av. age 56.1, 76.9% females). We observe a significant improvement in the mean over time in a pairwise comparison within the intervention group for the following: Pt-GA mean difference of 2.98 (p = 0.025, partial η2 = 0.353), pain mean difference of 1.46 (p = 0.049, partial η2 = 0.286) whereas all pairwise comparisons for the two parameters were non-significant in PG and CG. The patient reactions assessment (PRA) score, measuring patient perceived quality of the patient-provider relationship, increased by a mean of 4.15 points in IG, compared to a slight decrease of 1.92 for PG and 2.77 for CG.ConclusionThese preliminary findings show beneficial differences among the groups in favor of IG: 1) for quality of life and 2) the physician-patient-relationship. A digitally enhanced therapy is non-inferior to the gold-standard of exclusive in-person treatment. Patients seem willing and able to get involved in an enhanced treat-to-target and shared decision-making approach.References[1]Kernder A, Morf H, Klemm P, Vossen D, Haase I, Mucke J, et al.

Abstract
Oral cancer patients undergo diagnostic surgeries to detect occult lymph node metastases missed by preoperative structural imaging techniques. Reducing these invasive procedures that are associated with considerable morbidity, requires better preoperative detection. Multispectral optoacoustic tomography (MSOT) is a rapidly evolving imaging technique that may improve preoperative detection of (early-stage) lymph node metastases, enabling the identification of molecular changes that often precede structural changes in tumorigenesis. Here, we characterize the optoacoustic properties of cetuximab-800CW, a tumor-specific fluorescent tracer showing several photophysical properties that benefit optoacoustic signal generation. In this first clinical proof-of-concept study, we explore its use as optoacoustic to differentiate between malignant and benign lymph nodes. We characterize the appearance of malignant lymph nodes and show differences in the distribution of intrinsic chromophores compared to benign lymph nodes. In addition, we suggest several approaches to improve the efficiency of follow-up studies.

Abstract
In Western countries, recent decades have witnessed a revolution toward gender equality. Inequalities have been greatly reduced in areas such as education or employment. Because inequalities lead to distress, this development has largely benefited women. One notable exception is the realm of parenting, which has remained rife with inequalities even in the most egalitarian countries. We hypothesized that experiencing inequality in parenting when one holds egalitarian values and raising a child in a country characterized by a high level of gender equality in other areas, increases mothers’ psychological distress in the specific area of parenting. Multilevel modeling analyses computed among 11,538 mothers from 40 countries confirmed this prediction: high egalitarian values at the individual level and high gender equality at the societal level are associated with higher burnout levels in mothers. The associations hold beyond differences in sociodemographic characteristics at the individual level and beyond economic disparities at the societal level. These findings show the importance of egalitarian values and gender equality and their paradoxical effect when inequalities are still present in specific areas as parenting. This study reveals the crucial need to act not only at the micro level but also at the macro level to promote gender equality in parenting and prevent parental burnout.

Abstract
Role distribution is a central issue for parents in the transition to parenthood, but little is known about the motivations in fathers to assume a specific role. Differences in work-family balance in each parent may be motivated by an individual choice mutually shared by both partners; however, in many couples, the parents may feel forced to adopt a traditional role distribution, either for financial reasons, or to comply with social expectations about what men and women should do when they are parents. This feeling of being socially constrained to adopt a role distribution that is not congruent with intrinsic motivations can generate dissatisfaction and may jeopardize the development of the interparental relationship. Coparenting refers to the emotional and instrumental support parents bring to each other in their parental tasks. It has been shown to be central in family functioning and a powerful predictor of children's emotional and cognitive development. In this study, we aimed to assess the extent to which different motivations for role distribution in fathers are predictive of the quality of the coparental relationship. A convenience sample of 144 fathers from the French-speaking part of Switzerland completed online questionnaires about their motivations, coparental relationship, and sociodemographic characteristics. Results showed that the reasons for role distribution were mainly economical, practical, and in order to meet personal expectations. Multivariate general linear modeling showed that role distribution that is constrained to meet social expectations and age were predictive of a less cohesive coparental relationship, whereas a deliberate choice in role distribution was linked to a more cohesive coparental relationship.

Abstract
Abstract. The Coparenting Relationship Scale (CRS) is a 35-item parent-reported questionnaire designed to assess the quality of the coparental relationship. It was designed in the United States and validated in English. We present in this article a French adaptation of the CRS. A total of 399 participants from the French-speaking part of Switzerland (146 fathers, 253 mothers) completed the questionnaire. Confirmatory factor analysis showed that the theoretically grounded seven-factor structure of the original instrument was valid to explain the structure of the Swiss data. Metric measurement invariance was achieved when comparing mothers and fathers, but only configural invariance was achieved when comparing the original US sample and the Swiss sample. Intercultural differences may possibly explain this result. Convergent validity was tested against parent-reported task sharing and health-related issues in children. Results of multiple hierarchical regression analyses showed theoretically coherent links between the dimensions of the French version and these variables. The French version of the CRS is thus a valid instrument to assess the coparental relationship.

Abstract
Abstract
Background
35.3% of deaths in 2019 in Germany are caused by cardiovascular diseases (Destatis). 95% of these people were 60 years and older. To increase survival rate in elderly patients we investigate the relevance of altered expression of neuronal nitric oxide synthase 1 (NOS1) adaptor protein (NOS1AP) acting as an L-type calcium channel (CaV1.2) modulator via directing NOS1 to CaV1.2 on cardiac electrophysiology. Genome-wide association studies have linked genetic polymorphisms in NOS1AP to variations in QT interval duration (QTc). The QT interval reflects ventricular de- and repolarization. It may predispose individuals to ventricular tachycardia and sudden cardiac death (SCD) if prolonged, shortened or otherwise unregularly. In addition, about 20% of families with a clinically proven diagnosis of long QT syndrome (LQTS) host no mutation in any of the 16 associated genes.
Methods and results
Transgenic mice with conditional overexpression of NOS1AP in cardiac myocytes were used as model organism. We confirmed the interaction of NOS1AP with NOS1 and CaV1.2. Electrocardiography in NOS1AP overexpressing mice showed atrial and ventricular tachycardia both spontaneously and upon programmed stimulation associated with a significant decrease in QTc. Heart rates in NOS1AP overexpressing mice were similar to non-induced animals. Survival was significantly reduced (only 60% after 12 weeks vs. 100% in non-induced mice). Induced QTc alterations and accompanied deaths subsided upon re-administration of doxycycline.
Whole-cell patch-clamp measurements in isolated adult ventricular myocytes were performed and action potential duration at 90% of repolarization (APD90) was significantly reduced in induced transgenic NOS1AP overexpressing mice compared to control littermates.
In addition, we investigated the functional effect of the human SNP rs16847548 (T/C) located within the NOS1AP promoter. The SNP was found to decrease the transcriptional activity of NOS1AP in vitro and therefore, potentially leading to a decrease in NOS1AP expression in humans.
Conclusion
Myocardial overexpression of NOS1AP leads to short QT syndrome with increased susceptibility to atrial and ventricular arrhythmias and cardiac death. In accordance, APD90 is significantly shortened in overexpressing animals. The human SNP rs16847548, which is located in the promoter region of NOS1AP, results in a reduced NOS1AP promoter activity in vitro, hereby providing an explanation for the frequently published elongation of QT intervals. In summary, not only mutations in ion channels themselves but also genetic alterations in the expression of ion channel modulators such as NOS1AP, have an impact on QTc and arrhythmogenesis and represent a promising therapeutic target for LQTS patients.

Abstract
High levels of stress in the parenting domain can lead to parental burnout, a condition that has severe consequences for both parents and children. It is not yet clear, however, whether parental burnout varies by culture, and if so, why it might do so. In this study, we examined the prevalence of parental burnout in 42 countries (17,409 parents; 71% mothers; Mage = 39.20) and showed that the prevalence of parental burnout varies dramatically across countries. Analyses of cultural values revealed that individualistic cultures, in particular, displayed a noticeably higher prevalence and mean level of parental burnout. Indeed, individualism plays a larger role in parental burnout than either economic inequalities across countries, or any other individual and family characteristic examined so far, including the number and age of children and the number of hours spent with them. These results suggest that cultural values in Western countries may put parents under heightened levels of stress.

Abstract
Objective: ADHD is one of the most frequent neurodevelopmental disorders. In addition to clinical assessment, its diagnosis requires the use of validated and reliable behavior questionnaires such as the Conners' Parent Rating Scale-Revised: Short Form (CPRS-R:S). Though various French versions of the CPRS-R:S have been already put to use in clinical practice and research, only a few have undergone a stringent validation process. After a previous validation of the factorial structure of Lausanne French version, we sought here for the analysis of its invariance across sex and age. Method: This validation step was carried out in a rather homogeneous French population of 365 boys and 374 girls from a single school. Two-age classes were considered: children (boys and girls) aged 9 to 11 years (n = 258) and adolescents aged 12 to 15 years (n = 481). Results: Regarding age, dimension Oppositional showed a strong invariance whereas dimensions Hyperactivity and Cognitive problems/Inattention showed a partially strong invariance. Regarding sex, dimensions Oppositional and Hyperactivity showed a partially strong invariance whereas dimension Cognitive problems/Inattention showed a partially weak invariance. The distribution of the CPRS-R:S scores is given by sex and age class. Conclusion: The Lausanne French version of the CPRS-R:S, already validated regarding its factorial structure, internal consistency, and reliability, is here validated regarding its invariance across sex and age. Caution should be taken in using dimension Cognitive problems/Inattention in comparisons between boys and girls.

Abstract
Abstract
Background
Vancomycin is the recommended first-line therapy for mild to severe Clostridioides difficile infection (CDI). However, oral vancomycin is associated with disruption of the indigenous microbiota, predisposing patients to overgrowth of endogenous pathogens such as vancomycin-resistant enterococci.
Aims
The primary objective of the study is to examine the effect of the treatment regimens of CDI on the risk of infection with gram-negative organisms in adult patients treated for CDI.
Methods
A retrospective cohort study of 319 adult patients treated for CDI at Hamilton Health Sciences in the year 2015. A multivariate logistic regression analysis was performed to determine if oral vancomycin-based therapy is associated with an increased risk of infection with gram-negative organisms after adjustment for other factors.
Results
Eighty-one patients were excluded because of recurrent episodes of CDI within the same year or missing information. 238 patients were included in the final analysis. 48 (20.2%) patients had positive culture for gram-negative organisms after onset of CDI. Urine was the most common source for gram-negative organisms (39/48, 81.3%) followed by blood (8/48,16.7%). The most common isolated gram-negative organisms were Escherichia coli (18/48, 37.5%) and Klebsiella pneumonia (9/48, 18.8%).
The most common CDI treatment regimens were metronidazole monotherapy (137/238, 57.6%), vancomycin monotherapy (13/238, 5.5%), and combination therapy (88/238, 37.0%). Among patients who were treated with metronidazole monotherapy, vancomycin monotherapy, and combination therapy, 30(30/137, 21.9%), 3 (3/13,23.1%), and 15 (15/88, 17.1%) had positive culture for gram-negative organisms, respectively (P= 0.6).
Ninety-seven (97/238,40.8%) patients had severe CDI, 40 (40/97, 41.2%) were treated with metronidazole monotherapy, 5(5/97, 5.2%) with vancomycin monotherapy, and 52 (52/97, 53.6%) with combination therapy. 26 (26/141,18.4%) and 22 (22/97, 22.7%) had positive culture for gram-negative organisms among patients with non-severe and severe CDI, receptively (P= 0.7). In the multivariate analysis, neither type of CDI treatment regimen (P=0.2, 95% CI 0.30–1.31) nor CDI severity (P=0.4, 95% CI 0.67–2.69) was associated an increased risk of infection with gram-negative organisms after CDI onset.
Conclusions
Contrary to the reported literature, we did not find that oral vancomycin-based CDI treatment was associated with increased risk of infection with gram-negative organisms.

Abstract
Abstract
Background
Although volume- and pressure-overload (VO and PO, respectively) are hemodynamic stress, each results in distinct phenotypes. The Phosphodiesterase 4D interacting protein (PDE4DIP) is a protein involved in cardiac muscle contraction and suggested to play a role in cardiomyopathy. We previously identified Pde4dip transcript as being downregulated in VO but upregulated in PO.
Objective
We wanted to address whether Pde4dip deletion would alter the progression of pathological myocardial remodeling and heart failure (HF) following hemodynamic stress.
Methods
Pde4dip knockout (Pde4dip-KO) and age- and sex-matched wild-type (WT) mice were exposed to aortocaval shunt-triggered VO or transthoracic aortic constriction (TAC)-induced PO. Mortality rates were assessed and the cardiac structure and function were determined by serial echocardiography.
Results
The PDE4DIP protein levels decreased significantly in volume-overloaded hearts. However, pressure-overloaded hearts did not alter PDE4DIP protein levels, suggesting different posttranscriptional modifications that might affect the PDE4DIP protein expression in VO versus PO. The Pde4dip-KO Hearts were structurally and functionally normal in echocardiographic and morphometric analyses. However, Pde4dip deletion mildly attenuated the mortality rates in shunt-, but not in TAC-operated mice. A significant deterioration of left ventricle geometry and function was observed in volume-overloaded WT hearts at 12 weeks after shunt, but preserved cardiac function were noticed in shunt-operated Pde4dip-KO mice. On the other hand, TAC-operated WT and Pde4dip-KO mice exhibited a significant, but comparable deterioration of cardiac structure and function compared to sham mice.
Conclusion
Here we identified the PDE4DIP as an essential regulator of pathological myocardial remodeling following VO, but irrelevant to the development of cardiac dysfunction after TAC. Further investigations are warranted to dissect the possible mechanisms underlying the protective role of PDE4DIP deletion in the setting of VO.

Abstract
Zusammenfassung
Die Zunahme des medizinischen Wissens, technische Neuerungen gemeinsam mit demographischem Wandel stellen eine Herausforderung an die Neukonzeption von Leitlinien und klinischen Studien dar. Die vorliegende S2k-Leitlinie, die sich ausschließlich mit Nieren- und Harnleitersteinen beschäftigt, soll die Behandlung von Harnsteinpatienten in Klinik und Praxis unterstützen, aber auch Patienteninformationen zur Urolithiasis geben. Die zunehmende interdisziplinäre Zusammenarbeit in der Steintherapie zeigt sich auch an der Anzahl beteiligter Fachgruppen und Arbeitsgemeinschaften in der Erstellung des neuen Leitlinienupdates. Die vorliegende, aus einem interdisziplinären Konsensusprozess hervorgegangene S2k-Leitlinie stellt die aktuellen Empfehlungen praxisnah dar und gibt Entscheidungshilfen für Diagnostik‑, Therapie- und Metaphylaxemaßnahmen auf Basis von Expertenmeinungen und verfügbaren Evidenzgrundlagen aus der Literatur.

Abstract
BACKGROUND In histopathological routine diagnostics, three-dimensional tissue samples are analyzed histologically and/or immunohistochemically in two-dimensional sectional planes due to the high expenditure of time and the lack of digitization possibilities. AIM Here, we demonstrate the application of three-dimensional reconstruction to solid tumors and analyze inter-/intratumoral heterogeneity with respect to epithelial-mesenchymal transition (EMT). METHODS Tissue samples from pancreatic, lung, colorectal, and breast cancers as well as colorectal liver metastases were serially processed in 4μm sections. For individual analyses, alternating stains (cytokeratin AE1/3, zinc finger E‑box-binding homeobox 1 (ZEB1), eCadherin) were performed. Subsequently, the tumor cells were analyzed for their morphology (epitheloid amoeboid, mesenchymal) and the expression of ZEB1 and eCadherin. For statistical analysis, all tumor cell aggregates were hierarchically annotated and analyzed. RESULTS Tumor buds are predominantly associated with the main tumor mass. Furthermore, a shutteling of eCadherin could be observed within tumor cell aggregates smaller than nine cells. ZEB1 is only increasingly expressed in tumor cell groups smaller than five cells. CONCLUSIONS The initial tumor budding and the subsequent decoupling of the tumor bud from the main tumor mass is most likely a two-part process. However, the EMT is not statistically significantly increased within the tumor bud detached from the main tumor mass. It could be shown that the currently valid and known definition of a tumor bud as a cell cluster of less than or equal to five cells cannot be completely classified in the concept of EMT represented by eCadherin and ZEB1.

Abstract
ADHD is the most common psychiatric disorder of childhood. It is considered to be a neurodevelopmental disorder that may persist from chilhood into adulthood. In childood it is associated with several outcomes such as inattention, hyperactivity and impulsivity. Symptoms may change as a person gets older with an increased risk of developing psychiatric comorbidities such as depression, anxiety and substance addiction. However, recent studies diverge from the traditional perspective. These authors hypothesized that ADHD may appear in adulthood, not as a continuation of child ADHD, but some limitations have to be considered. Firstly, ADHD often goes unrecognized throughout childhood. Secondly, families may help the children to develop compensation strategies and adaptative behaviors. The purpose of this report is to better investigate these different and innovative clinical results and understand if adult ADHD could really be considered as a distinct, different pathology, as a late-onset disorder. We conducted a brief review of literature and included the most recent scientific longitudinal follow-up cohort studies. We conclude that, while adult ADHD is still considered a continuation from childhood, many questions of late-onset ADHD remain and further research is necessary to better understand and explain the etiology, the development, the clinical impact, and the psychotherapeutic and pharmacologic treatment of this late-onset disorder.

Abstract
Objective The receptor MAS, encoded by Mas1, is expressed in microglia and its activation has been linked to anti-inflammatory actions. However, microglia are involved in several different processes in the central nervous system, including the promotion of angiogenesis. We therefore hypothesized that the receptor MAS also plays a role in angiogenesis via microglia. Approach and results To assess the role of MAS on vascular network development, flat-mounted retinas from 3-day-old wild-type (WT) and Mas1−/− mice were subjected to Isolectin B4 staining. The progression of the vascular front was reduced (− 24%, p < 0.0001) and vascular density decreased (− 38%, p < 0.001) in Mas1−/− compared to WT mice with no change in the junction density. The number of filopodia and filopodia bursts were decreased in Mas1−/− mice at the vascular front (− 21%, p < 0.05; − 29%, p < 0.0001, respectively). This was associated with a decreased number of vascular loops and decreased microglial density at the vascular front in Mas1−/− mice (-32%, p < 0.001; − 26%, p < 0.05, respectively). As the front of the developing vasculature is characterized by reduced oxygen levels, we determined the expression of Mas1 following hypoxia in primary microglia from 3-day-old WT mice. Hypoxia induced a 14-fold increase of Mas1 mRNA expression (p < 0.01). Moreover, stimulation of primary microglia with a MAS agonist induced expression of Notch1 (+ 57%, p < 0.05), Dll4 (+ 220%, p < 0.001) and Jag1 (+ 137%, p < 0.001), genes previously described to mediate microglia/endothelial cell interaction during angiogenesis. Conclusions Our study demonstrates that the activation of MAS is important for microglia recruitment and vascular growth in the developing retina.

Abstract
Although, cognitive working memory training (CWMT) has been reported to enhance working memory functioning in youths with attention-deficit/ hyperactivity disorder (ADHD), few studies take into account the concomitant effects of medication. Sixty adolescents aged from 11 to 15 years were randomly assigned to CWMT treatment, whereas medication was either continued or not introduced (no randomization performed). Results revealed beneficial effects of CWMT on the different components of working memory (WM), namely the phonological loop, the visuospatial sketchpad and the central executive. In particular, CWMT allowed participants to obtain a level of performance similar to the typically-developing adolescents for the phonological loop (i.e., forward digit span) as well as for the visuospatial sketchpad (i.e., board span). For the central executive (i.e., backward digit span) the concomitant effects of CWMT and medication allows participants to obtain the performance level of the typically-developing adolescents. Although, no transfers were observed with respect to other cognitive functions, in medicated patients with ADHD, CWMT reduced hyperactivity / impulsivity symptoms at 2-month follow-up. The present study gives evidence of the efficacy of CWMT to enhance WM performance, as well as, to reduce symptoms. The overall results highlight the usefulness of multimodal interventions.

Abstract
Attention-deficit hyperactivity disorder (ADHD) is characterized by deficits in executive functions and decision making during childhood and adolescence. Contradictory results exist whether altered event-related potentials (ERPs) in adults are associated with the tendency of ADHD patients toward risky behavior. Clinically diagnosed ADHD patients (n = 18) and healthy controls (n = 18), aged between 18 and 29 (median 22 Yo), were screened with the Conners' Adult ADHD Rating Scales and assessed by the Mini-International Neuropsychiatric Interview, adult ADHD Self-Report Scale, and by the 60-item HEXACO Personality Inventory. The characteristic personality traits of ADHD patients were the high level of impulsiveness associated with lower values of agreeableness. All participants performed a probability gambling task (PGT) with two frequencies of the feedback information of the outcome. For each trial, ERPs were triggered by the self-paced trial onset and by the gamble selection. After trial onset, N2-P3a ERP component associated with the attentional load peaked earlier in the ADHD group than in controls. An N500 component related to the feedback frequency condition after trial onset and an N400-like component after gamble selection suggest a large affective stake of the decision making and an emphasized post-decisional evaluation of the choice made by the ADHD participants. By combining ERPs, related to the emotions associated with the feedback frequency condition, and behavioral analyses during completion of PGT, this study provides new findings on the neural dynamics that differentiate controls and young ADHD adults. In the patients' group, we raise the hypothesis that the activity of frontocentral and centroparietal neural circuits drive the decision-making processes dictated by an impaired cognitive workload followed by the build-up of large emotional feelings generated by the conflict toward the outcome of the gambling choice. Our results can be used for new investigations aimed at studying the fine spatiotemporal distribution of cortical activity, and the neural circuits that underly the generation of that activity, associated with the behavioral deficits characteristic of ADHD.

Abstract
Our aim was to evaluate whether endothelial overexpressing of the bradykinin B1 receptor could be associated with altered left ventricular and myocardial performance. Echocardiography and hemodynamic were employed to assess left ventricular morphology and function in Sprague Dawley transgenic rats overexpressing the endothelial bradykinin B1 receptor (Tie2B1 rats). The myocardial inotropism was evaluated on papillary muscles contracting in vitro. In Tie2B1 animals, an enlarged left ventricular cavity and lower fractional shortening coupled with a lower rate of pressure change values indicated depressed left ventricular performance. Papillary muscle mechanics revealed that both Tie2B1 and wild-type rat groups had the same contractile capacities under basal conditions; however, in transgenic animals, there was accentuated inotropism due to post-pause potentiation. Following treatment with the Arg(9)-BK agonist, Tie2B1 papillary muscles displayed a reduction in myocardial inotropism. Endothelial B1 receptor overexpression has expanded the LV cavity and worsened its function. There was an exacerbated response of papillary muscle in vitro to a prolonged resting pause, and the use of a B1 receptor agonist impairs myocardial inotropism.

Abstract
Calcineurin dephosphorylates nuclear factor of activated T cells transcription factors, thereby facilitating T cell-mediated immune responses. Calcineurin inhibitors are instrumental for immunosuppression after organ transplantation but may cause side effects, including hypertension and electrolyte disorders. Kidneys were recently shown to display activation of the furosemide-sensitive Na-K-2Cl cotransporter (NKCC2) of the thick ascending limb and the thiazide-sensitive Na-Cl cotransporter (NCC) of the distal convoluted tubule upon calcineurin inhibition using cyclosporin A (CsA). An involvement of major hormones like angiotensin II or arginine vasopressin (AVP) has been proposed. To resolve this issue, the effects of CsA treatment in normal Wistar rats, AVP-deficient Brattleboro rats, and cultured renal epithelial cells endogenously expressing either NKCC2 or NCC were studied. Acute administration of CsA to Wistar rats rapidly augmented phosphorylation levels of NKCC2, NCC, and their activating kinases suggesting intraepithelial activating effects. Chronic CsA administration caused salt retention and hypertension, along with stimulation of renin and suppression of renal cyclooxygenase 2, pointing to a contribution of endocrine and paracrine mechanisms at long term. In Brattleboro rats, CsA induced activation of NCC, but not NKCC2, and parallel effects were obtained in cultured cells in the absence of AVP. Stimulation of cultured thick ascending limb cells with AVP agonist restored their responsiveness to CsA. Our results suggest that the direct epithelial action of calcineurin inhibition is sufficient for the activation of NCC, whereas its effect on NKCC2 is more complex and requires concomitant stimulation by AVP.

Abstract
BACKGROUND Following a train derailment, several tons of acrylonitrile (ACN) exploded, inflamed and part of the ACN ended up in the sewage system of the village of Wetteren. More than 2000 residents living in the close vicinity of the accident and along the sewage system were evacuated. A human biomonitoring study of the adduct N-2-cyanoethylvaline (CEV) was carried out days 14-21 after the accident. OBJECTIVES (1) To describe the short-term health effects that were reported by the evacuated residents following the train accident, and (2) to explore the association between the CEV concentrations, extrapolated at the time of the accident, and the self-reported short-term health effects. METHODS Short-term health effects were reported in a questionnaire (n=191). An omnibus test of independence was used to investigate the association between the CEV concentrations and the symptoms. Dose-response relationships were quantified by Generalized Additive Models (GAMs). RESULTS The most frequently reported symptoms were local symptoms of irritation. In non-smokers, dose-dependency was observed between the CEV levels and the self-reporting of irritation (p=0.007) and nausea (p=0.007). Almost all non-smokers with CEV concentrations above 100pmol/g globin reported irritation symptoms. Both absence and presence of symptoms was reported by non-smokers with CEV concentrations below the reference value and up to 10 times the reference value. Residents who visited the emergency services reported more symptoms. This trend was seen for the whole range of CEV concentrations, and thus independently of the dose. DISCUSSION AND CONCLUSION The present study is one of the first to relate exposure levels to a chemical released during a chemical incident to short-term (self-reported) health effects. A dose-response relation was observed between the CEV concentrations and the reporting of short-term health effects in the non-smokers. Overall, the value of self-reported symptoms to assess exposure showed to be limited. The results of this study confirm that a critical view should be taken when considering self-reported health complaints and that ideally biomarkers are monitored to allow an objective assessment of exposure.

Abstract
OBJECTIVE Attention-deficit hyperactivity disorder is one of the most frequent neurodevelopmental disorders. Its diagnosis requires reference questionnaires such as the Conners' Parent Rating Scale (CPRS). Presently, in French-speaking countries, a few translations of the revised short CPRS have been put to use without previous formal validation. We sought here for the validation of a French version (Lausanne, Switzerland) of the revised short CPRS regarding construct validity, internal consistency, and item reliability in a sample of French schoolchildren. METHOD The study involved 795 children and adolescents aged 9 to 19 years from a single school. The factorial structure and item reliability were assessed with a confirmatory factor analysis for ordered categorical variables. The dimension internal consistency was assessed with Guttman's lambda 6 coefficient. RESULTS The results confirmed the original and strong 3-dimensional factorial structure (Oppositional, Cognitive Problems/Inattention, and Hyperactivity), showed satisfactory item reliability, and indicated a good dimension internal consistency (Guttman's lambda 6 coefficient: 0.87, 0.90, and 0.82, respectively, to the 3 dimensions). CONCLUSIONS Thus, the Lausanne French version of the revised short CPRS may be considered validated regarding construct validity and item and dimension reliability; it can be now more confidently used in clinical practice.

Abstract
Direct lineage conversion is a promising approach for disease modeling and regenerative medicine. Cell divisions play a key role in reprogramming of somatic cells to pluripotency, however their role in direct lineage conversion is not clear. Here we used transdifferentiation of fibroblasts into neuronal cells by forced expression of defined transcription factors as a model system to study the role of cellular division in the direct conversion process. We have shown that conversion occurs in the presence of the cell cycle inhibitors aphidicolin or mimosine. Moreover, overexpression of the cell cycle activator cMyc negatively influences the process of direct conversion. Overall, our results suggest that cell divisions are not essential for the direct conversion of fibroblasts into neuronal cells.

Abstract
INTRODUCTION Large retrospective studies of people with posterior urethral valves (PUV) have reported chronic renal insufficiency (CRI) in up to one third of the participants and end-stage renal failure in up to one quarter of them. Nadir creatinine (lowest creatinine during the first year following diagnosis) is the recognised prognostic indicator for renal outcome in PUV, the most commonly used cut-off being 1 mg/dl (88.4 umol/l). OBJECTIVE To conduct a statistical analysis of nadir creatinine in PUV patients in order to identify the optimal cut-off level as a prognostic indicator for CRI. STUDY DESIGN Patients treated by endoscopic valve ablation at the present institution between 1993 and 2004 were reviewed. Chronic renal insufficiency was defined as CKD2 or higher. Statistical methods included receiver operating characteristic (ROC) curve analysis, Fisher exact test and diagnostic utility tests. Statistical significance was defined as P < 0.05. RESULTS AND DISCUSSION Nadir creatinine was identified in 96 patients. The median follow-up was 9.4 (IQR 7.0, 13.4) years. A total of 29 (30.2%) patients developed CRI, with nine (9.4%) reaching end-stage renal failure. On ROC analysis, Nadir creatinine was highly prognostic for future CRI, with an Area Under the Curve of 0.887 (P < 0.001). Renal insufficiency occurred in all 10 (100%) patients with nadir creatinine >88.4 umol/l compared with 19 of 86 (22.2%) patients with lower nadir creatinine (P < 0.001). As a test for future CRI, a nadir creatinine cut-off of 88.4 umol/l gave a specificity of 100%, but poor sensitivity of 34.5%. Lowering the cut-off to 75 umol/l resulted in improvement in all diagnostic utility tests (Table). All 14 (100%) patients with nadir creatinine >75 umol/l developed CRI, compared with 15 of 82 (18.3%) patients with lower nadir creatinine (P < 0.001). Sensitivity only approached 95% at 35 umol/l, at which level specificity was low (Table). Two out of 36 (5.6%) patients with nadir creatinine <35 umol/l developed CRI. Multivariate analysis found recurrent UTI (OR 4.733; CI 1.297-17.280) and nadir creatinine >75 umol/l (OR 48.988; CI 4.9-490.11) to be independent risk factors for progression to CRI. Using cut-off values of 35 umol/l and 75 umol/l, patients can be stratified into low-, intermediate- and high-risk groups, with development of CRI in 5.3%, 28.3% and 100%, respectively (P <0.001). The stage of CKD was higher in higher risk groups. CONCLUSION Patients with nadir creatinine >75 umol/l (0.85 mg/dl) should be considered at high risk for CRI, while patients with nadir creatinine ≤35 umol/l (0.4 mg/dl) should be considered low risk. Patients with nadir creatinine between these two values have an intermediate risk of CRI.

Abstract
A deficit in brain serotonin is thought to be associated with deteriorated stress coping behaviour, affective disorders and exaggerated violence. We challenged this hypothesis in mice with a brain-specific serotonin depletion caused by a tryptophan hydroxylase 2 (TPH2) deficiency. We tested TPH2-deficient (Tph2(-/-)) animals in two social situations. As juveniles, Tph2(-/-) mice displayed reduced social contacts, whereas ultrasonic vocalizations (USVs) were unchanged within same-sex same-genotype pairings. Interestingly, juvenile females vocalized more than males across genotypes. Sexually naive adult males were exposed to fresh male or female urine, followed by an interaction with a conspecific, and re-exposed to urine. Although Tph2(-/-) mice showed normal sexual preference, they were hyper-aggressive towards their interaction partners and did not vocalize in response to sexual cues. These results highlight that central serotonin is essential for prosocial behaviour, especially USV production in adulthood, but not for sexual preference.

Abstract
AIM The renal renin-angiotensin system (RAS) has been implicated in the pathogenesis of diabetic nephropathy. The aim of this study was to investigate sex differences in renal renin-angiotensin system (RAS) and the roles of androgens in diabetes-associated renal injury. METHODS Renal injury and fibrosis were studied in streptozotocin-induced diabetic rats by albuminuria and by gene expression of collagen I and fibronectin. RAS was investigated by analysing the plasma angiotensinogen (AOGEN) and renin activity (PRA) and their renal gene expression. Also, a group of diabetic rats was treated with the anti-androgen flutamide. RESULTS Albuminuria was significantly lower in diabetic females than in males (1.2 [0.8-1.5] versus 4.4 [2.2-6.1] mg/24 h, data are median [IQR] values, P < 0.05). Renal AOGEN mRNA levels were increased by diabetes in males (8.1 ± 0.8% in diabetes versus 0.8 ± 0.2% in control, P < 0.001) but not in females (1.0 ± 0.1% in diabetes versus 0.8 ± 0.1% in control, P > 0.05), as were collagen I and fibronectin mRNAs. Furthermore, AOGEN mRNA levels were strongly correlated with albuminuria (Spearman r = 0.64, 95% [CI] 0.36-0.81, P < 0.0001). Diabetes decreased PRA, renal renin mRNA and plasma AOGEN in both females and males. Anti-androgen treatment decreased albuminuria only in diabetic males without affecting the endocrine or renal RAS. CONCLUSIONS These data indicate that renal but not hepatic AOGEN or renin is positively associated with diabetic albuminuria and contribute to the sex-dependent differences in renal injury. Androgens may contribute to albuminuria in male independently of the RAS.

Abstract
Cancer cell invasion takes place at the cancer-host interface and is a prerequisite for distant metastasis. The relationships between current biological and clinical concepts such as cell migration modes, tumour budding and epithelial-mesenchymal transition (EMT) remains unclear in several aspects, especially for the 'real' situation in human cancer. We developed a novel method that provides exact three-dimensional (3D) information on both microscopic morphology and gene expression, over a virtually unlimited spatial range, by reconstruction from serial immunostained tissue slices. Quantitative 3D assessment of tumour budding at the cancer-host interface in human pancreatic, colorectal, lung and breast adenocarcinoma suggests collective cell migration as the mechanism of cancer cell invasion, while single cancer cell migration seems to be virtually absent. Budding tumour cells display a shift towards spindle-like as well as a rounded morphology. This is associated with decreased E-cadherin staining intensity and a shift from membranous to cytoplasmic staining, as well as increased nuclear ZEB1 expression.

Abstract
Bradykinin B2 receptor is involved in many processes, including the regulation of blood pressure and smooth muscle contraction, vasodilation, inflammation, edema, cell proliferation, pain. It is suggested that this receptor may be one of the factors that have cardioprotective and infarct-limiting effects. It is assumed that certain genetic variants in both coding and non-coding regions ofBDKRB2 gene may influence its expression. In the 3'-untranslated region of BDKRB2 exon 3 the minisatellite repeat B2-VNTR is located. B2-VNTR has previously been shown to affect the BDKRB2 mRNA stability. Therefore, it is important to perform the molecular genetic analysis of this minisatellite in patients with different forms of coronary heart disease in order to reveal possible associations between specific B2-VNTR alleles and certain clinical forms of coronary heart disease. In the present study, a comparative analysis of the allele and genotype frequencies of B2-VNTR was carried out in groups of healthy individuals and patients with two clinical forms of coronary heart disease (angina pectoris and myocardial infarction), ethnically Russian. The results of the B2-VNTR length polymorphism analysis indicate that this tandem repeat may be attributed to a class of low polymorphic and non-hypervariable minisatellite. In all analyzed groups we revealed three B2-VNTR alleles, consisting of 43, 38 and 33 repeat units. Alleles of 43 and 33 repeats were major in all investigated groups. No statistically significant differences were found in the B2-VNTR allele and genotype frequencies between men and women in control group, and also between healthy men and men with angina pectoris and myocardial infarction. Thus, B2-VNTR length polymorphism was not associated with these clinical forms of coronary heart disease in Russian men. However, we do not exclude the possibility of association between the B2-VNTR short alleles (38 and 33 repeats) and cardioprotective effects of bradykinin B2 receptor in women with coronary heart disease. This hypothesis requires further investigation.

Abstract
During the oestrus cycle, varying spine synapse density correlates positively with varying local synthesis of oestradiol in the hippocampus. In this context, the roles of the oestrogen receptor (ER) subtypes ERα and β are not fully understood. In the present study, we used neonatal hippocampal slice cultures from female rats because these cultures synthesise oestradiol and express both receptor subtypes, and inhibition of oestradiol synthesis in these cultures results in spine synapse loss. Using electron microscopy, we tested the effects on spine synapse density in response to agonists of both ERα and ERβ. Application of agonists to the cultures had no effect. After inhibition of oestradiol synthesis, however, agonists of ERα induced spine synapse formation, whereas ERβ agonists led to a reduction in spine synapse density in the CA1 region of these cultures. Consistently, up-regulation of ERβ in the hippocampus of adult female aromatase-deficient mice is paralleled by hippocampus-specific spine synapse loss in this mutant. Finally, we found an increase in spine synapses in the adult female ERβ knockout mouse, but no effect in the adult female ERα knockout mouse. Our data suggest antagonistic roles of ERβ and ERα in spine synapse formation in the female hippocampus, which may contribute to oestrus cyclicity of spine synapse density in the hippocampus.
