Abstract
Motor cortical circuit functions depend on the coordinated fine-tuning of two functionally diverse neuronal populations: glutamatergic pyramidal neurons providing synaptic excitation and GABAergic interneurons adjusting the response of pyramidal neurons through synaptic inhibition. Microglia are brain resident macrophages which dynamically refine cortical circuits by monitoring perineuronal extracellular matrix and remodelling synapses. Previously, we showed that colony-stimulating factor 1 receptor (CSF1R)-mediated myeloid cell depletion extended the lifespan, but impaired motor functions of MBP29 mice, a mouse model for multiple system atrophy. In order to better understand the mechanisms underlying these motor deficits we characterized the microglial involvement in the cortical balance of GABAergic interneurons and glutamatergic pyramidal neurons in 4-months-old MBP29 mice following CSF1R inhibition for 12 weeks. Lack of myeloid cells resulted in a decreased number of COUP TF1 interacting protein 2-positive (CTIP2+) layer V pyramidal neurons, however in a proportional increase of calretinin-positive GABAergic interneurons in MBP29 mice. While myeloid cell depletion did not alter the expression of important presynaptic and postsynaptic proteins, the loss of cortical perineuronal net area was attenuated by CSF1R inhibition in MBP29 mice. These cortical changes may restrict synaptic plasticity and potentially modify parvalbumin-positive perisomatic input. Collectively, this study suggests, that the lack of myeloid cells shifts the neuronal balance toward an increased inhibitory connectivity in the motor cortex of MBP29 mice thereby potentially deteriorating motor functions.

Abstract
INTRODUCTION SARS-CoV-2 is a viral disease with potentially devastating effects. Observational studies of pregnant women infected with SARS-CoV-2 report an increased risk for FGR. This study utilizes data from a prospective SARS-CoV-2 registry in pregnancy, investigating the progression of fetuses to fetal growth restriction (FGR) at birth following maternal SARS-CoV-2 and evaluating the hypothesis of whether the percentage of SGA at birth is increased after maternal SARS-CoV-2 taking into account the time interval between infection and birth. MATERIALS & METHODS CRONOS is a prospective German registry enrolling pregnant women with confirmed SARS-CoV-2 infection during their pregnancy. SARS-CoV-2 symptoms, pregnancy- and delivery-specific information were recorded. The data evaluated in this study range from March 2020 until August 2021. Women with SARS-CoV-2 were divided into three groups according to the time of infection/symptoms to delivery: Group I<2 weeks, Group II 2-4 weeks, and Group III>4 weeks. FGR was defined as estimated and/or birth weight<10% ile, appropriate for gestational age (AGA) was within 10 and 90%ile, and large for gestational age (LGA) was defined as fetal or neonatal weight>90%ile. RESULTS Data for a total of 2,650 SARS-CoV-2-positive pregnant women were available. The analysis was restricted to symptomatic cases that delivered after 24+0 weeks of gestation. Excluding those cases with missing values for estimated fetal weight at time of infection and/or birth weight centile, 900 datasets remained for analyses. Group I consisted of 551 women, Group II of 112 women, and Group III of 237 women. The percentage of changes from AGA to FGR did not differ between groups. However, there was a significantly higher rate of large for gestational age (LGA) newborns at the time of birth compared to the time of SARS-CoV-2 infection in Group III (p=0.0024), respectively. CONCLUSION FGR rates did not differ between symptomatic COVID infections occurring within 2 weeks and>4 weeks before birth. On the contrary, it presented a significant increase in LGA pregnancies in Group III. However, in this study population, an increase in the percentage of LGA may be attributed to pandemic measures and a reduction in daily activity.

Abstract
The growing recognition of a dichotomous role of astrocytes in neurodegenerative processes has heightened the need for unraveling distinct astrocytic subtypes in neurological disorders. In multiple system atrophy (MSA), a rare, rapidly progressing atypical Parkinsonian disease characterized by increased astrocyte reactivity. However the specific contribution of astrocyte subtypes to neuropathology remains elusive. Hence, we first set out to profile glial fibrillary acidic protein levels in astrocytes across the human post mortem motor cortex, putamen, and substantia nigra of MSA patients and observed an overall profound astrocytic response. Matching the post mortem human findings, a similar astrocytic phenotype was present in a transgenic MSA mouse model. Notably, MSA mice exhibited a decreased expression of the glutamate transporter 1 and glutamate aspartate transporter in the basal ganglia, but not the motor cortex. We developed an optimized astrocyte isolation protocol based on magnetic-activated cell sorting via ATPase Na+/K+ transporting subunit beta 2 and profiled the transcriptomic landscape of striatal and cortical astrocytes in transgenic MSA mice. The gene expression profile of astrocytes in the motor cortex displayed an anti-inflammatory signature with increased oligodendroglial and pro-myelinogenic expression pattern. In contrast, striatal astrocytes were defined by elevated pro-inflammatory transcripts accompanied by dysregulated genes involved in homeostatic functions for lipid and calcium metabolism. These findings provide new insights into a region-dependent, dichotomous astrocytic response-potentially beneficial in the cortex and harmful in the striatum-in MSA suggesting a differential role of astrocytes in MSA-related neurodegenerative processes.

Abstract
Introduction Studies have shown that pregnant women with COVID-19 have a higher risk of intensive care unit admission and invasive mechanical ventilation support than non-pregnant women. Pregnancy-associated physiological changes in respiratory function may contribute to the elevated risk. Alteration in lung volumes and capacities are attributed to the mechanical impediment caused by the growing fetus. Multiple pregnancies may therefore compromise functional lung capacity earlier than singleton pregnancies and contribute to severe respiratory symptoms of COVID-19. Materials and Methods A total of 5514 women with a symptomatic SARS-CoV-2 infection during pregnancy registered in the COVID-19 Related Obstetric and Neonatal Outcome Study were included. The COVID-19-related adverse maternal outcomes were compared in 165 multiple versus 5349 singleton pregnancies. Combined adverse maternal outcome was defined as presence of COVID-19-related hospitalization and/or pneumonia and/or oxygen administration and/or transfer to ICU and/or death. Multivariate logistic regression was used to estimate the odds ratios and 95% confidence intervals were calculated. Results The frequency of dyspnea, likelihood of developing dyspnea in a defined pregnancy week and duration of the symptomatic phase of the COVID-19 infection did not differ between the two groups. On average, COVID-19-related combined adverse outcome occurred earlier during pregnancy in women expecting more than one child than in singleton pregnancies. The overall incidence of singular and combined COVID-19-associated adverse maternal outcomes was not significantly different between groups. However, regression analysis revealed that multiple gestation, preconceptional BMI > 30 kg/m 2 and gestational age correlated significantly with an increased risk of combined adverse maternal outcome. Conversely, maternal age and medically assisted reproduction were not significant risk factors for combined adverse maternal outcome. Conclusion Our data show that multiple gestation alone is a risk factor for COVID-19-associated combined adverse maternal outcome. Moreover, severe courses of COVID-19 in women expecting more than one child are observed earlier in pregnancy than in singleton pregnancies.

Abstract
INTRODUCTION Acute subdural hematoma (aSDH) is one of the main causes of high mortality and morbidity in traumatic brain injury. Prognosis is poor due to the rapid volume shift and mass effect. Cerebral perfusion is likely affected in this condition. This study quantifies perfusion changes in aSDH using early ER polytrauma CT with perfusion imaging (CTP). METHODS Data of 54 patients with traumatic aSDH were retrospectively collected. Glasgow Coma scale (GCS), perfusion parameters, therapeutic decisions and imaging data including hematoma thickness, midline shift, and hematoma localization were analyzed. The cortical perfusion parameters of each hemisphere, the area anterior to the hematoma (AAH), area below the hematoma (ABH), area posterior to the hematoma (PAH), and corresponding mirrored contralateral regions were determined. RESULTS We found a significant difference in Tmax in affected and unaffected whole-hemisphere data (mean 4.0 s vs. 3.3 s, p < 0.05) and a significantly different mean for Tmax in ABH and for the corresponding mirrored area (mABH) (mean 3.8 s vs. 3.1 s, p < 0.05). No significant perfusion changes in cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) were found. CONCLUSION There was a significant elevation of time to maximum (Tmax) values in the underlying cortical area of aSDH. Possible pathophysiological explanations, the influence on immediate surgical decision-making and further therapeutic consequences have to be evaluated.

Abstract
Pathogenic heterozygous variants in SCN2A, which encodes the neuronal sodium channel NaV1.2, cause different types of epilepsy or intellectual disability (ID)/autism without seizures. Previous studies using mouse models or heterologous systems suggest that NaV1.2 channel gain-of-function typically causes epilepsy, whereas loss-of-function leads to ID/autism. How altered channel biophysics translate into patient neurons remains unknown. Here, we investigated iPSC-derived early-stage cortical neurons from ID patients harboring diverse pathogenic SCN2A variants [p.(Leu611Valfs*35); p.(Arg937Cys); p.(Trp1716*)] and compared them with neurons from an epileptic encephalopathy (EE) patient [p.(Glu1803Gly)] and controls. ID neurons consistently expressed lower NaV1.2 protein levels. In neurons with the frameshift variant, NaV1.2 mRNA and protein levels were reduced by ~ 50%, suggesting nonsense-mediated decay and haploinsufficiency. In other ID neurons, only protein levels were reduced implying NaV1.2 instability. Electrophysiological analysis revealed decreased sodium current density and impaired action potential (AP) firing in ID neurons, consistent with reduced NaV1.2 levels. In contrast, epilepsy neurons displayed no change in NaV1.2 levels or sodium current density, but impaired sodium channel inactivation. Single-cell transcriptomics identified dysregulation of distinct molecular pathways including inhibition of oxidative phosphorylation in neurons with SCN2A haploinsufficiency and activation of calcium signaling and neurotransmission in epilepsy neurons. Together, our patient iPSC-derived neurons reveal characteristic sodium channel dysfunction consistent with biophysical changes previously observed in heterologous systems. Additionally, our model links the channel dysfunction in ID to reduced NaV1.2 levels and uncovers impaired AP firing in early-stage neurons. The altered molecular pathways may reflect a homeostatic response to NaV1.2 dysfunction and can guide further investigations.

Abstract
OBJECTIVE The aim of this study was to investigate the influence of obstructive sleep apnea and continuous positive airway pressure on the nasal microbiome. PATIENTS AND METHODS Endonasal swabs from the olfactory groove of 22 patients with moderate and severe obstructive sleep apnea (OSA) and a control group of 17 healthy controls were obtained at the Department of Otorhinolaryngology of the Friedrich-Alexander-Universität Erlangen-Nürnberg. 16S rRNA gene sequencing was performed to further evaluate the endonasal microbiome. In a second step, the longitudinal influence of continuous positive airway pressure (CPAP) therapy on the nasal microbiome was investigated (3-6 and 6-9 months). RESULTS Analysis of the bacterial load and β-diversity showed no significant differences between the groups, although patients with severe OSA showed increased α-diversity compared to the control group, while those with moderate OSA showed decreased α-diversity. The evaluation of longitudinal changes in the nasal microbiota during CPAP treatment showed no significant difference in α- or β-diversity. However, the number of bacteria for which a significant difference between moderate and severe OSA was found in the linear discriminant analysis decreased during CPAP treatment. CONCLUSIONS Long-term CPAP treatment showed an alignment of the composition of the nasal microbiome in patients with moderate and severe OSA as well as an alignment of biodiversity with that of the healthy control group. This change in the composition of the microbiome could be both part of the therapeutic effect in CPAP therapy and a promoting factor of the adverse side effects of the therapy. Further studies are needed to investigate whether the endonasal microbiome is related to CPAP compliance and whether CPAP compliance can be positively influenced in the future by therapeutic modification of the microbiome.

Abstract
Lower Austria is by size the biggest province of Austria and located in the heart of Europe with a 414 km long border to the Czech Republic and Slovakia, and in close proximity to Hungary. Not only through its geographic location but also through its understanding to be a connected region as part of a strong European Union, cross-border health care plays an important issue at the provincial level. Led by the European spirit, all international and cross-border health activities are bundled under the umbrella of the ‘Healthacross initiative”. The initiative is part of the Health Agency of Lower Austria (NÖ Landesgesundheitsagentur), which operates and manages all 27 public hospitals and around 50 care/nursing homes in the region. Via the “Healthacross initiative”, Lower Austria is participating in four transnational networks and since 2008, conducted eight EU co-funded projects in cross-border healthcare, four of them currently running. Healthacross is the coordinator of this session, with support of WHO RHN network. Active networking in various European and international networks is part of the regional strategy of Lower Austria in order to gain excellence to improve the health and quality of life for citizens living in border regions. The premise is to enable equal access to health care services for citizens, regardless of their place of residence. The current epidemiological situation with the COVID-19 pandemic has not only impact on cross-border healthcare, but also on the life, health and well-being of citizens. With the closure of national borders, the exchange of healthcare services came to an interim halt; solely dialog remained - which was incredibly valuable for both commuters and citizens living in the border regions. Lower Austria will take care of the moderation of the session and will be represented by Julia Winkler.

Abstract
OBJECTIVE Alterations in mitochondrial function play an important role in the development of various diseases, such as obesity, insulin resistance, steatohepatitis, atherosclerosis and cancer. However, accurate assessment of mitochondrial respiration ex vivo is limited and remains highly challenging. Using our novel method, we measured mitochondrial oxygen consumption (OCR) and extracellular acidification rate (ECAR) of metabolically relevant tissues ex vivo to investigate the impact of different metabolic stressors on mitochondrial function. METHODS Comparative analyses of OCR and ECAR were performed in tissue biopsies of young mice fed 12 weeks standard-control (STD), high-fat (HFD), high-sucrose (HSD), or western diet (WD), matured mice with HFD, and 2year-old mice aged on STD with and without fasting. RESULTS While diets had only marginal effects on mitochondrial respiration, respiratory chain complexes II and IV were reduced in adipose tissue (AT). Moreover, matured HFD-fed mice showed a decreased hepatic metabolic flexibility and prolonged aging increased OCR in brown AT. Interestingly, fasting boosted pancreatic and hepatic OCR while decreasing weight of those organs. Furthermore, ECAR measurements in AT could indicate its lipolytic capacity. CONCLUSION Using ex vivo tissue measurements, we could extensively analyze mitochondrial function of liver, AT, pancreas and heart revealing effects of metabolic stress, especially aging.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
BACKGROUND Convolutional neural networks (CNNs) efficiently differentiate skin lesions by image analysis. Studies comparing a market-approved CNN in a broad range of diagnoses to dermatologists working under less artificial conditions are lacking. MATERIALS AND METHODS One hundred cases of pigmented/non-pigmented skin cancers and benign lesions were used for a two-level reader study in 96 dermatologists (level I: dermoscopy only; level II: clinical close-up images, dermoscopy, and textual information). Additionally, dermoscopic images were classified by a CNN approved for the European market as a medical device (Moleanalyzer Pro, FotoFinder Systems, Bad Birnbach, Germany). Primary endpoints were the sensitivity and specificity of the CNN's dichotomous classification in comparison with the dermatologists' management decisions. Secondary endpoints included the dermatologists' diagnostic decisions, their performance according to their level of experience, and the CNN's area under the curve (AUC) of receiver operating characteristics (ROC). RESULTS The CNN revealed a sensitivity, specificity, and ROC AUC with corresponding 95% confidence intervals (CI) of 95.0% (95% CI 83.5% to 98.6%), 76.7% (95% CI 64.6% to 85.6%), and 0.918 (95% CI 0.866-0.970), respectively. In level I, the dermatologists' management decisions showed a mean sensitivity and specificity of 89.0% (95% CI 87.4% to 90.6%) and 80.7% (95% CI 78.8% to 82.6%). With level II information, the sensitivity significantly improved to 94.1% (95% CI 93.1% to 95.1%; P < 0.001), while the specificity remained unchanged at 80.4% (95% CI 78.4% to 82.4%; P = 0.97). When fixing the CNN's specificity at the mean specificity of the dermatologists' management decision in level II (80.4%), the CNN's sensitivity was almost equal to that of human raters, at 95% (95% CI 83.5% to 98.6%) versus 94.1% (95% CI 93.1% to 95.1%); P = 0.1. In contrast, dermatologists were outperformed by the CNN in their level I management decisions and level I and II diagnostic decisions. More experienced dermatologists frequently surpassed the CNN's performance. CONCLUSIONS Under less artificial conditions and in a broader spectrum of diagnoses, the CNN and most dermatologists performed on the same level. Dermatologists are trained to integrate information from a range of sources rendering comparative studies that are solely based on one single case image inadequate.

Abstract
Abstract
Background
The disturbance of cardiac energy substrate metabolism has a decisive role in the pathogenesis of adverse cardiac remodeling and heart failure. Under normoxic conditions, the free fatty acid metabolism is the predominant pathway by providing the highest energy per substrate molecule. Severe myocardial hypoxia leads to a switch from beta-oxidation to glucose metabolism to increase the ATP production per oxygen molecule. This metabolic disorder appears as perfusion-metabolism mismatch in 18F-fluorodeoxyglucose (18F-FDG) PET images, as increased 18F-FDG uptake in the under-perfused hypoxic myocardial area.
Purpose
The aim of our study was to evaluate the simultaneous perfusion, metabolism and function of the ischemic heart by hybrid 18F-FDG-PET-cMRI with late enhancement images in a translation animal model of heart failure.
Methods
Under general anesthesia, closed chest reperfused acute myocardial infarction (AMI) was induced in 36 domestic pigs by 90 min occlusion of the mid left anterior descending artery with a percutaneous intracoronary balloon, followed by reperfusion. Three days and 1 month after AMI, after 12h fasting, 18F-FDG-PET-cMRI were performed by using standardized acquisition protocols (n=30). Cardiac functional parameter, such as ejection fraction (EF), end-diastolic volume (EDV), infarct size, and mean tracer uptake of the infarcted area were quantitatively assessed. Six animals were euthanized after the 3-day 18F-FDG-PET-cMRI images to elaborate the differences in gene expression patterns in animals with perfusion-metabolic mismatch by using next generation sequencing (NGS) and pathway network analyses.
Results
Eight (group Mismatch) of the 30 animals (group Match) with 1-month follow-up showed high 18F-FDG uptake in the infarcted area (perfusion-metabolism mismatch) at the 3-day 18F-FDG-PET-cMRI-LE images (Figure). The animals in the Mismatch group had significantly lower EF at 3 days (34±8.8 vs 42±3%) and at the 1-month follow-up (35.8±6 vs 43±6.6%) and larger infarct size at day 3 (26.6±6.6 vs 22.1±4.4%) and 1 month (28±5.4 vs 20.3±4.3%) with higher EDV at 1 month. Mean tracer uptake of the infarcted area was significantly reduced in the Mismatch group at 1 month (56±23.1 vs 64.7±13.2%). NGS revealed downregulation of the cholesterol metabolism pathway, and upregulation of carbohydrate derivative catabolism pathway with highly activated innate immune system and genes responsible for cytokine activation in the infarcted area 3 days post-AMI in the Mismatch group, which explains the paradox high 18F-FDG tracer uptake in the infarction zone. Accordingly, the high energy demand of the severe hypoxic area led to “glucose steel phenomenon” at the molecular level, subtracting the 18F-FDG from the normally perfused non-ischemic myocardial regions.
Conclusions
18F-FDG-glucose perfusion-metabolism mismatch early after AMI visualized by hybrid 18F-FDG-PET-MRI images predict development of LV adverse remodeling.

Abstract
Abstract
Background
Long-term survival of xenogeneic transplanted cells in adults requires strong immunosuppression and/or encapsulation of the cells to achieve peripheral transplant tolerance.
Purpose
The aim of our project was to seed decellularized tissue engineered heart valves (TEHV) with xenogeneic (porcine) mesenchymal stem cells (pMSCs) transfected transiently (Lipofectamine) with a positron emission tomography (PET)-reporter gene (pMSC-PETr), followed by implantation as pulmonary valve replacement into sheep without immunosuppression. The fate of the seeded pMSC-PETr was tracked via serial in-vivo non-invasive PET-computed tomography (PET-CT).
Methods
Static cultivation of TEHV scaffold led to successful ingrowth of the pMSC-PETr. For enabling quantitative assessment of viable pMSC-PETr in the TEHV scaffold after in vivo implantation, vials containing 5x104, 2x105, and 4x105 pMSC-PETr were in vitro mixed with the [18F]-FHBG PET tracer for 1 hr, then the non-bound tracer was washed out and vials were in vitro PET-CT imaged, giving reference values. TEHV-pMSC-PETr were then implanted percutaneously into the pulmonary valve position of sheep (n=4) under general anesthesia, while an additional sheep with no valve implantation served as a control. Ten mCi of [18F]-FHBGPET radiotracer was produced for each procedure and serial PET-CT imaging of the sheep was performed at 3 hr, 24 hr, 2 or 3 weeks, and 5 and 6 months after valve implantation. The study followed the Principles of laboratory animal care.
Results
PET-CT of vials containing increasing number of pMSC-PETr showed dose-dependent tracer uptake in the transfected cells in vitro (Figure). PET-CT images of the sheep 3 hr after implantation of the TEHV-pMSC-PETr showed a clear signal of transfected cells, with a mean estimated number of viable pMSC-PETr of 5.18±1.19x106. No meaningful decrease of the amount of living cells occurred at 24 hr or 2 or 3 weeks. Interestingly, 5- and 6-month follow-up PET-CT images showed clear in vivo and in vitro (after explantation) PET signals of the pMSC-PETr on TEHV, indicating spontaneous stable transfection of the PET reporter plasmid (insertional mutagenesis). Histology confirmed the survival of the pMSC-PETr at 5 and 6-month after xenogeneic transplantation. Merged immunohistochemistry and fluorescence imaging of anti-pig SLA I and anti-sheep MHC I antibodies and PET-reporter gene (HSV1-tk) suggested in vivo inter-species lateral jump gene transfer between pig MSCs and host sheep cells.

Conclusions
This is the first report on serial non-invasive in vivo tracking of long-term survival of xenogeneic pMSCs-PETr seeded on TEHVs and percutaneously implanted into the pulmonary position of sheep. Long-term follow-up revealed spontaneous stable transfection of the plasmid PET-reporter gene, which suggests the risk of insertional mutagenesis induced by the plasmid (transposon), and PET-reporter gene shuttle from xenogeneic pig MSCs to sheep cells.

Abstract
Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion theory of planet formation. We report the discovery of a giant planet around the very-low-mass star GJ 3512, as determined by optical and near-infrared radial-velocity observations. The planet has a minimum mass of 0.46 Jupiter masses, very high for such a small host star, and an eccentric 204-day orbit. Dynamical models show that the high eccentricity is most likely due to planet-planet interactions. We use simulations to demonstrate that the GJ 3512 planetary system challenges generally accepted formation theories, and that it puts constraints on the planet accretion and migration rates. Disk instabilities may be more efficient in forming planets than previously thought.

Abstract
Collaborative & Proactive Solutions (CPS) is a psychosocial treatment model for behaviorally challenging youth, which has been applied in a diverse array of settings, including families, schools, and therapeutic facilities. Numerous studies have documented its effectiveness and examined factors that mediate and moderate the effectiveness of the model. Data have thus far shown that, with regard to behavioral improvements, CPS is at least the equivalent of the standard of care for externalizing youth, Parent Management Training, and that CPS may hold additional benefits as regards parent-child interactions and children's skill enhancement.

Abstract
INTRODUCTION Minimal invasive plate osteosynthesis in simple distal meta or diaphyseal tibia fractures can be applied using absolute (lag screw and neutralisation plate; LSN) or relative stability (bridge plate; BP). The primary aim of the study was to compare time to radiological union and time to full weight bearing in the two groups (LSN vs. BP). Reduction was performed either percutaneously or by a minimally open approach (mini open). Secondary aim was to analyse the number of complications between both groups. METHODS Retrospective single centre review of patients with a simple distal meta or diaphyseal tibia fracture operated with a Locking Compression Plate (LCP) between 2009 and 2015 in a Level one Trauma Centre. Postoperative radiographs were assessed in a standardised manner. Time to radiological fracture union and time to full weight bearing were observed. Callus index and postoperative complications were analysed. RESULTS Fifty-seven patients with a minimum follow-up of 6 months were analysed. Forty-eight patients had a shaft (AO/OTA Type 42) and nine a distal tibia fracture (AO/OTA Type 43). Forty patients were treated with using the LSN concept and 17 patients with the BP concept. Median time to radiological fracture union was statistically significant shorter (p=0.04) in the LSN group with 19 weeks compared to 27 weeks in the BP-group. Time to full weight bearing was 10 weeks in both groups. A total (including implant removal) of 35 reoperations were performed in the LSN-group and 18 in the BP-group. Wound healing disorders (deep surgical site infections) were seen less the LSN group in 3/40 (7.5%) compared to the BP-group with 3/17 (17.6%). In the LSN group, there was no statistical difference in time to union or weight bearing between a percutaneous or mini open approach. CONCLUSION Stable osteosynthesis of simple distal meta or diaphyseal tibia fractures leads to faster radiologic fracture healing without an increase in complications or number of revisions compared to bridge plating. If a percutaneous reduction is not feasible for the insertion of a lag screw, a mini-open approach does not lead to a delay in fracture healing.

Abstract
Parkinson's disease (PD) is the most common age-related movement disorder and characterized by slowly progressive neurodegeneration resulting in motor symptoms, such as bradykinesia, rigidity, tremor and postural instability. Moreover, non-motor symptoms, such as hyposmia, anxiety and depression reduce the quality of life in PD. Motor symptoms are associated with a distinct striatal dopaminergic deficit resulting from axonal dysfunction and neuronal loss in the substantia nigra (SN). Recent progress in stem cell technology allows the optimization of cellular transplantation strategies in order to alleviate the motor deficit, which potentially leads to a reactivation of this therapeutic strategy. Besides neurodegenerative processes impaired adult neurogenesis and consequentially reduced endogenous cellular plasticity may play an important role in PD. This article discusses the notion that non-motor symptoms in PD may partly be explained by reduced adult neurogenesis in the olfactory bulb and hippocampus.

Abstract
Parkinsonism may result from cerebral vascular disorders that feature white matter lesions and small vessel pathology. Vascular Parkinsonism typically presents as lower body Parkinsonism with predominant gait impairment. Urinary incontinence and cognitive decline are additional features of the disease. There is a considerable overlap between vascular Parkinsonism and vascular dementia. We review the clinical characteristics of vascular Parkinsonism and discuss the current treatment approaches, as well as the role of brain imaging for the diagnostic workup. .

Abstract
Abstract 6 Background: Breast cancer incidence is increasing in developing countries. In 2010, 57.8% of breast cancers in Peru were at least stage III at diagnosis. Federal and regional Peruvian institutions partnered with several organizations, including UCSF, to improve access and quality of breast cancer care in Peru. Phase 1 involved screening with clinical breast exam, creating a community-based referral system for women with masses, and promoting evaluation of lesions using fine needle aspiration biopsy (FNAB) by trained physicians, with treatment at the regional cancer institute. Curricula for each activity were developed and validated. During phase 1, in-country FNAB expertise was recognized as limited. For phase 2, the critical objective was to solidify local capacity for high-quality FNAB and integrate FNAB into standard of care for breast cancer. Methods: Three main activities were completed during phase 2. 1) Develop a Training of Trainers (ToT) curriculum for FNAB, and identify master trainers and trainees. 2) Facilitate endorsement of a national approach to training FNAB and undertake preliminary rollout in La Libertad region. 3) Strengthen interpretation and reporting of FNAB results. Results: A 5-day ToT pilot course occurred during October 19-23, 2014. Prior to the course, women with palpable masses were identified during a breast screening campaign and scheduled for FNAB. Regional, national and international clinical teams observed, procured and interpreted FNAB. Four new cases of cancer and eight cases of granulomatous mastitis were diagnosed. Slide quality before and after the training intervention will be compared. Following the course, a one-day validation meeting including physicians and national leaders took place at the national cancer center in Lima, Peru. FNAB was endorsed for early diagnosis and triage. Conclusions: To ensure sustainability of FNAB, cytology fellowships and training centers are needed. Strengthening partnerships will be critical for long-term capacity. An electronic reporting system will be developed to replace paper-based methods. Funding: Norwegian Cancer Society/Norwegian Breast Cancer Society (NCS/NBCS), Susan G.

Abstract
IntroductionRisperidone-ISM is a new long-acting intramuscular formulation intended to achieve sustained plasma concentrations over 4 weeks without oral supplementation. The clinical efficacy to risperidone has been associated with 65–80% occupancy of dopamine D2 receptor (D2RO) and a mean Cmax between 7.5 ng/mL and 80 ng/mL.AimUse a population PK/PD model to predict the PK and the D2RO for Risperidone-ISM in schizophrenic patients and to characterize the relationship among doses, in order to guide dose selection for a future Phase-III trial.MethodsA population PK/PD analysis for Risperidone-ISM using Monolix software was conducted based on 6641 plasma samples from two Phase-I studies (17 healthy subjects and 31 schizophrenic subjects, respectively) and 1 Phase-II study (60 schizophrenic subjects). Simulations were subsequently undertaken predicting the steady state PK and D2RO after multiple Risperidone-ISM doses administered every 28 days for 12 weeks.ResultsDoses of 75 and 100 mg, administered either in gluteal or deltoid muscle, were predicted to result in median Cmax and Ctrough that stayed between 7.5 ng/mL and 80 ng/mL. At steady state 75 mg and 100 mg dose (gluteal) achieved a D2RO average [min–max] of 70.8% [61.4–80.4] and 74.3% [66.2–82.1], respectively; a 75-mg and 100-mg dose (deltoid) achieved a D2RO average [min–max] of 69.3% [56.5–80.3] and 73.0% [61.8–82.1], respectively. The model estimated that the 65% D2RO occurs within first 8 h after treatment.ConclusionsSimulations were carried out supporting doses of 75 mg and 100 mg Risperidone-ISM to show the greatest efficacy and safety potential to be assessed in the future Phase-III trial.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Patients with pulmonary hypertension (PH) are at high risk when undergoing surgery. Up to one-third of patients suffer complications; recent studies report a mortality rate of 1 to 7%. Frequent events are deterioration of right heart function and infectious or bleeding complications. METHODS Data of patients (age ≥ 18) with precapillary PH who need to undergo elective surgery between January 2006 and March 2015 were included in this retrospective analysis. All patients who were planned for surgery underwent the same procedure. First, patients were evaluated in the PH center. Thereafter, PH-relevant data were discussed with the surgeon/anesthesiologist team for risk-adapted planning of anesthesia and intervention. The present analysis comprises patient characteristics and information about surgery and post-interventional course. RESULTS This study analyzes 31 surgical procedures carried out in PH patients (male: n = 8; PH-group I: n = 23, group III: n = 3, group IV: n = 5, mean age: 59.5 ± 15.3 years). Patients were characterized by compromised hemodynamics and exercise capacity: pulmonary vascular resistance: 805.4 ± 328.5 dyn*s*cm(-5), mean pulmonary arterial pressure: 46.3 ± 9.3 mmHg, 6-minute walking distance: 350.3 ± 123.3 m.The majority of interventions were performed under general anesthesia (n = 24). In 25 cases, the intraoperative monitoring was complemented with right heart catheterization.Eight interventions were associated with complications, three of which were serious. One patient died postoperatively owing to sepsis and right heart failure. CONCLUSION A careful and structured planning of surgical interventions in patients with PH and the choice of surgical procedure and anesthesia adapted to the conditions of PH might help avoid complications. Further multicentric studies are needed.

Abstract
INTRODUCTION Olfactory dysfunction and neuropsychological symptoms like depression and anhedonia are common non-motor symptoms in Parkinson's disease (PD). The assessment of both functional domains includes clinical examination, olfactory testing, and standardized questionnaires. While olfaction is readily assessed by functional tests, the distinction of anhedonia as a separate symptom from other depressive symptoms is challenging. Thus, a test focusing on the assessment of hedonic olfaction may be helpful in the assessment of neuropsychological symptoms in PD. METHODS We examined anhedonia by evaluating the perception of pleasantness of odors in PD patients (n = 57) and healthy controls (n = 46). Pleasantness of odors was registered on a visual 9-point scale. For the assessment of anhedonia we used the Snaith-Hamilton-Pleasure-Scale (SHAPS). Depression was evaluated with the Zung Self-Rating Depression Scale and the Beck Depression Inventory II. RESULTS PD patients showed a substantial reduction in hedonic olfaction compared to controls (hedonic score: 1.5 vs. 2.2). Hyposmia, one of the most prevalent non-motor symptoms in PD, was a confounding factor. However, even normosmic PD patients showed a reduced hedonic olfaction compared to controls (hedonic score: 1.6 vs. 2.2). Furthermore, we observed a correlation between hedonic olfaction and the SHAPS-score for PD patients even though positive SHAPS-rating was observed in 9% of PD patients only, while no correlation to depression was present. CONCLUSION These findings suggest that reduced hedonic olfaction might be an additional neuropsychological feature, probably giving insights into changes in hedonic tone complementary to hyposmia and depression in PD.

Abstract
COPD is a heterogeneous disease with a wide range of clinical phenotypes and breath-functional dysfunctions. Cardiopulmonary exercise testing (CPET) allows describing all component parts of breathing and determining exercise capacity and the mechanisms of exercise limitation. From these aspects 64 COPD patient stages II, III and IV according to the conventional GOLD classification were examined by means of CPET to evaluate whether CPET can provide a better functional characterization of COPD than the standard investigation procedures in pulmonary practice.We could show that in pulmonary practice CPET is safely and effectively practicable in stable COPD patients of all GOLD stages. This method allowed a clinical and prognostic disease severity assessment of all patients, proving important differences of peak oxygen uptake in each GOLD stage, so that patients in spite of identical GOLD disease severity were to be assigned to different prognostic groups according CPET criteria. Furthermore, we found relevant differences of individual breath-functional patterns in exercise, which can neither be objectified nor be prognosticated by standard investigation procedures at rest.Therefore CPET allows, aside from an objective clinical and prognostic disease severity assessment, also a breath-functional evaluation in a subtly way in COPD patients reflecting the multidimensional background of the disease with variable dysfunctions in pulmonary ventilation, gas exchange, circulation and muscular function as well as associated cardio vascular comorbidities. The breath-functional phenotyping of the COPD patient seems to be meaningful in particular for an individualised therapy management.
