Abstract
The current state-of-the-art analysis of central nervous system (CNS) tumors through DNA methylation profiling relies on the tumor classifier developed by Capper and colleagues, which centrally harnesses DNA methylation data provided by users. Here, we present a distributed-computing-based approach for CNS tumor classification that achieves a comparable performance to centralized systems while safeguarding privacy. We utilize the t-distributed neighborhood embedding (t-SNE) model for dimensionality reduction and visualization of tumor classification results in two-dimensional graphs in a distributed approach across multiple sites (DistSNE). DistSNE provides an intuitive web interface (https://gin-tsne.med.uni-giessen.de) for user-friendly local data management and federated methylome-based tumor classification calculations for multiple collaborators in a DataSHIELD environment. The freely accessible web interface supports convenient data upload, result review, and summary report generation. Importantly, increasing sample size as achieved through distributed access to additional datasets allows DistSNE to improve cluster analysis and enhance predictive power. Collectively, DistSNE enables a simple and fast classification of CNS tumors using large-scale methylation data from distributed sources, while maintaining the privacy and allowing easy and flexible network expansion to other institutes. This approach holds great potential for advancing human brain tumor classification and fostering collaborative precision medicine in neuro-oncology.

Abstract
A multiple pump-terahertz probe experiment enables the clear distinction between elastic and inelastic scattering of excitons with a free electron-hole plasma in (Ga,In)As multiquantum wells. Low plasma energies dictate the prevalence of elastic scattering by inhibiting inelastic processes due to the absence of final states for quasiparticles. Yet, an increased plasma energy results in a progressive destruction of excitons. Notably, despite plasma energy variations, the interaction strength between excitons and the electron-hole plasma remains unaltered.

Abstract
Convolutional neural networks (CNNs) are becoming increasingly valuable tools for advanced computational histopathology, promoting precision medicine through exceptional visual decoding abilities. Meningiomas, the most prevalent primary intracranial tumors, necessitate accurate grading and classification for informed clinical decision-making. Recently, DNA methylation-based molecular classification of meningiomas has proven to be more effective in predicting tumor recurrence than traditional histopathological methods. However, DNA methylation profiling is expensive, labor-intensive, and not widely accessible. Consequently, a digital histology-based prediction of DNA methylation classes would be advantageous, complementing molecular classification. In this study, we developed and rigorously assessed an attention-based multiple-instance deep neural network for predicting meningioma methylation classes using tumor methylome data from 142 (+51) patients and corresponding hematoxylin-eosin-stained histological sections. Pairwise analysis of sample cohorts from three meningioma methylation classes demonstrated high accuracy in two combinations. The performance of our approach was validated using an independent set of 51 meningioma patient samples. Importantly, attention map visualization revealed that the algorithm primarily focuses on tumor regions deemed significant by neuropathologists, offering insights into the decision-making process of the CNN. Our findings highlight the capacity of CNNs to effectively harness phenotypic information from histological sections through computerized images for precision medicine. Notably, this study is the first demonstration of predicting clinically relevant DNA methylome information using computer vision applied to standard histopathology. The introduced AI framework holds great potential in supporting, augmenting, and expediting meningioma classification in the future.

Abstract
PURPOSE/OBJECTIVE(S) To report objective characteristics of program directors (PDs) and chairpersons and examine contemporary trends of their demographic and academic profiles from 2013 to 2023. We hypothesize that there are significant changes in the profiles of our radiation oncology leaders over the past decade. MATERIALS/METHODS A total of 89 PDs and 85 chairpersons in the Accreditation Council for Graduate Medical Education (ACGME)-approved residency programs in the U.S were queried for analysis. Demographic data on race, ethnicity, post graduate training, years in practice were obtained from publicly available online resources (e.g., institutional websites and online networking services for physicians). Variables on academic productivity and professional accolades included Hirsh-index, National Institute of Health (NIH) research grant (R), the ASTRO fellowship designation, and leadership positions in professional society meetings. Descriptive analyses, including Fisher's exact tests, were performed to compare findings from the published article in 2013 on this topic (Wilson LD et al. IJROBP 2013). RESULTS A total of 36 out of 89 PDs (40.4%) and 11 out of 85 chairpersons (12.8%) were females, revealing higher proportion of females from the initial analysis: 40.4 vs. 24.1% for PDs (p = 0.025) and 12.8 vs. 9.2% for chairpersons (p = 0.618). 29 out of 89 (32.6%) PDs and 30 out of 85 (35.3%) chairpersons were non-White. The median length of practice for PDs and chairpersons were 11 and 29 years, respectively. 38 out of 89 PDs (42.7%) and 11 out of 85 (12.9%) chairpersons were employed at the institution of their training. 7 out of 89 (7.9%) for PDs and 51 out of 85 (60.0%) for chairpersons were awarded FASTRO designation. Median H-index showed increasing trends for PDs (14.5 vs 9) and chairpersons (40 vs 29) from the initial analysis. CONCLUSION While most PDs and chairpersons are males, female representation has increased in radiation oncology leadership in the last 10 years, most notably among PDs. Academic productivity among our leaders has also increased. These trends highlight the changes in the landscape of our leadership characteristics.

Abstract
BACKGROUND Intrahospital transport (IHT) of Neurosurgical Intensive Care Unit (NICU) patients for cranial computed tomography (CCT) scans is associated with a high rate of complications. The potential of serum biomarkers to estimate the risk for complications associated with IHT and improve their safety remains underexplored. The present study investigated the influence of several serum biomarkers on IHT-associated complications in brain-injured NICU patients. METHODS A total of 523 IHTs in 223 NICU patients were prospectively analyzed (05/2019-05/2020). Hemoglobin, hematocrit, serum sodium, and albumin levels were evaluated as serum biomarkers. Each patient's demographic data, CCT scan, NICU parameters and modified Rankin Scale at discharge as well as indications, consequences, and complications of IHTs were analyzed. RESULTS In 58.7% of all IHTs, at least one IHT-associated complication was observed with 60.1% of all IHTs having no therapeutic consequence. Significantly lower rates of increased intracranial pressure (ICP; P<0.0001), decreased cerebral perfusion pressure (CPP; P=0.03) as well as hemodynamic (P<0.0001) and pulmonary events (P=0.01) were observed in patients with higher hemoglobin levels prior to IHT. Additionally, higher hematocrit levels before IHT were associated with a fewer rate of hemodynamic (P<0.0001), pulmonary (P=0.006), ICP (P<0.0001), and CPP (P=0.01) events. CONCLUSIONS Higher levels of hemoglobin and hematocrit are associated with less complications with respect to ICP, CPP, hemodynamic and pulmonary events during IHT in NICU patients. Therefore, these biomarkers may be helpful for risk assessment of potential complications prior to IHT.

Abstract
The negative prognostic value of an increased serum urea-to-albumin ratio on intra-hospital mortality is frequently investigated in general critically ill patients and patients with septic shock, although not in neurosurgical patients with spontaneous intracerebral hemorrhages (ICH). The current study was conducted to investigate the impact of the serum urea-to-albumin ratio upon hospital admission on intra-hospital mortality in ICU-admitted neurosurgical patients with spontaneous ICH. METHODS This retrospective study analyzed 354 ICH patients, who were treated from 10/2008 to 12/2017 at our intensive care units (ICU). Blood samples were taken upon admission, and the patients' demographic, medical, and radiological data were analyzed. A binary logistic regression analysis was performed for the identification of independent prognostic parameters for intra-hospital mortality. RESULTS Overall, the intra-hospital mortality rate was 31.4% (n = 111). In the binary logistic analysis, a higher serum urea-to-albumin ratio (OR = 1.9, CI = 1.23-3.04, p = 0.005) upon admission was identified as an independent predictor of intra-hospital mortality. Furthermore, a serum urea-to-albumin ratio cut-off level of >0.01 was associated with raised intra-hospital mortality (Youden's index = 0.32, sensitivity = 0.57, specificity = 0.25). CONCLUSION A serum urea-to-albumin ratio greater than 1.1 seems to be a prognostic marker to predict intra-hospital mortality in patients with ICH.

Abstract
OBJECTIVE Cardiopulmonary (CP) complications are well-known phenomena in patients with isolated traumatic brain injury (iTBI) that can lead to tissue hypoperfusion and hypoxia. Serum lactate level is a well-known biomarker, indicating these systemic dysregulations in various diseases, but this has not been investigated in iTBI patients so far. The current study evaluates the association between serum lactate levels upon admission and CP parameters within the first 24 h of intensive care unit (ICU) treatment in iTBI patients. PATIENTS AND METHODS 182 patients with iTBI who were admitted to our neurosurgical ICU between December 2014 and December 2016 were retrospectively evaluated. Serum lactate levels on admission, demographic, medical, and radiological data upon admission, as well as several CP parameters within the first 24 h of ICU treatment, were analyzed, as well as the functional outcome at discharge. The total study population was dichotomized into patients with an elevated serum lactate level (lactate-positive) and patients with a low serum lactate level (lactate-negative) upon admission. RESULTS 69 patients (37.9%) had an elevated serum lactate level upon admission, which was significantly associated with a lower Glasgow Coma Scale score (p = 0.04), a higher head AIS score (p = 0.03), and a higher Acute Physiology and Chronic Health Evaluation II score (p = 0.01) upon admission, as well as a higher modified Rankin Scale score (p = 0.002) and a lower Glasgow Outcome Scale score (p < 0.0001) at discharge. Furthermore, the lactate-positive group required a significantly higher norepinephrine application rate (NAR; p = 0.04) and a higher fraction of inspired oxygen (FiO2; p = 0.04) to maintain the defined CP parameters within the first 24 h. CONCLUSION ICU-admitted iTBI patients with elevated serum lactate levels upon admission required higher CP support within the first 24 h of ICU treatment after iTBI. Serum lactate may be a helpful biomarker for improving ICU treatment in the early stages.

Abstract
BACKGROUND High-mobility group AT-hook protein 2 (HMGA2) is a gene regulatory protein that is correlated with metastatic potential and poor prognosis. It has been shown that HMGA2 is overexpressed in various tumors such as lung cancer or pancreatic cancer. The invasive character and highly aggressive structure of glioblastoma let us to investigate HMGA2 expression in the border zone of the tumor more closely. We compared HMGA2 expression between glioblastoma and normal brain tissue. In addition, we analyzed and compared HMGA2 expression in the border and center zones of tumors. Correlation tests between HMGA expression and clinical parameters such as MGMT-status and survival were performed. METHODS Samples from 23 patients with WHO grade 4 glioblastomas were analyzed for HMGA2 expression using quantitative real-time polymerase chain reaction (qPCR) and immunohistochemistry (IHC) and correlated with clinical parameters. The areas from the tumor center and border were analyzed separately. Two normal brain tissue specimens were used as the controls. RESULTS Our results confirm that HMGA2 is higher expressed in glioblastoma compared to healthy brain tissue (qPCR, P=0.013; IHC, P=0.04). Moreover, immunohistochemistry revealed significantly higher HMGA2 expression in the border zone of the tumor than in the tumor center zone (P=0.012). Survival analysis revealed a tendency for shorter survival when HMGA2 was highly expressed in the border zone. CONCLUSIONS The results reveal an overexpression of HMGA2 in the border zone of glioblastomas; thus, the expression cluster of HMGA2 seems to be heterogenous and thorough borough surgical resection of the vital and aggressive border cells might be important to inhibit the invasive character of the tumor.

Abstract
Controlling and improving processes like for example the production of organic semiconductors via printing depends on understanding the interplay of wetting and evaporation of complex fluids. Therefore, examination of the time dependent composition of complex fluid droplets during wetting or evaporation is of interest. The evaporation rate of sessile droplets containing largely water depends on the vapor pressures of the individual components and on the humidity (or partial pressure) of the surrounding gas phase. Hence, for a complete picture of an evaporation process and the comparability of the results of different measurements, it is essential to measure and control the humidity and temperature in the measurement compartment. Accordingly, climate chambers are available in different scales to fit a variety of techniques like contact angle goniometry to obtain results in a controlled atmosphere. We recently reported the application of MRI (Magnetic Resonance Imaging) and spatially resolved NMR (Nuclear Magnetic Resonance) spectroscopy for the examination of the evaporation of sessile droplets on surfaces in 10 mm NMR tubes. These are considered to be closed compartments. Here, we present an apparatus to a) measure and b) control the relative humidity within the sample compartment of the NMR setup by introducing preconditioned gas into the NMR tube. We monitored the evaporation of water droplets using RARE images and compared the volume decay with a) a simple diffusive evaporation model and b) with detailed FEM (finite element numerical model) simulations using COMSOL for validation. We find three evaporation regimes depending on the flow rate as well as on the distance of the gas outlet and the evaporating droplet. In one of the sample configurations tested the evaporation takes place in such a way that it can be described with the help of the simple diffusive model without convection. Thus, the presented approach opens comparative measurements with other methods as well as the observation of droplet evaporation in very dry or very humid environments with and without the influence of convection. Finally, using PRESS spectra, it is shown that the evaporation rate of water from a water/DMSO droplet can be controlled. This shows how the setup presented here can be used to study the evaporation of droplets of more complex mixtures.

Abstract
Objective: Cardiopulmonary (CP) complications are well known in patients with an intracerebral hemorrhage (ICH) and could be associated with a higher serum lactate level. The present study aimed to assess the associations between the initial serum lactate level and the CP parameters within the first 24 h of intensive care unit (ICU) treatment in neurosurgical ICH patients. Patients and Methods: A total of 354 patients admitted to the ICU between 01/2009 and 12/2017 with a diagnosis of an ICH were retrospectively analyzed. Blood samples were taken upon admission, and each patient’s demographic, medical, and radiological data upon admission, as well as several CP parameters, were recorded within the first 24 h of ICU treatment. Results: A higher serum lactate level was associated with a lower GCS score (p < 0.0001), as well as a higher Acute Physiology and Chronic Health Evaluation II score (p = 0.002) upon admission. Additionally, patients with initially higher serum lactate levels had a significantly higher need for a norepinephrine application (p = 0.004) and inspiratory oxygen fraction (p = 0.03) within the first 24 h. Conclusion: Neurosurgical ICH patients with higher serum lactate levels upon admission require more CP support within the first 24 h of ICU treatment.

Abstract
Abstract
Background
Long total stent length and small stent diameter have been associated with adverse events following percutaneous coronary intervention (PCI).
Purpose
To assess whether stent length and -diameter influence long-term target-lesion failure (TLF) following implantation of contemporary drug-eluting stents (DES) in an all-comers population undergoing PCI.
Methods
Patients included in the ReCre8 trial were stratified for troponin status and diabetes and randomized to implantation of a permanent polymer (PP-ZES) or polymer-free stent (PF-AES). Troponin negative patients were treated with dual antiplatelet therapy for one month, and troponin positive patients for twelve months. For the analysis on stent length, patients were divided in the quartiles of total stent length implanted per patient. Group 1a had a stent length of ≤18mm, Group 2a had a total stent length between 18 and 30mm, Group 3a had a total stent length of ≥30mm and lower than 49mm, and Group 4a had a total stent length of 49mm or more. For the analysis on stent diameter, patients were divided in the quartiles of the smallest stent diameter implanted per patient. Group 1b had a minimal stent diameter of ≤2.5mm, Group 2b had a minimal stent diameter between 2.5 and 3mm, Group 3b had a minimal stent diameter of ≥3mm and lower than 3.5mm, and Group 4b had a minimal stent diameter of 3.5mm or higher. The primary endpoint of TLF and its components – cardiac death, target-vessel myocardial infarction and target-lesion revascularization (TLR) – were assessed after three years.
Results
After division of patients in subgroups based on stent length, Group 1a included 409 patients (27.6%), Group 2a included 322 patients (20.7%), Group 3a included 376 patients (25.3%) and Group 4a included 377 patients (25.4%). After three years, TLF occurred more frequently in Group 4a with 6.6% in Group 1a, 8.4% in Group 2a, 7.7% in Group 3a and 18.0% in Group 4a (p<0.001) as shown in Figure 1. This was driven by a higher rate of TLR (p<0.001) and target-vessel myocardial infarction (p<0.001) in Group 4a. After division of patients in subgroups based on stent diameter, Group 1b included 408 patients (27.5%), Group 2b included 214 patients (14.4%), Group 3b included 477 patients (32.1%) and Group 4b included 386 patients (26.0%). After three years, TLF occurred more frequently in Group 1b with 14.0% vs. 7.9% in Group 2b, 8.6% in Group 3b and 9.3% in Group 4b (p=0.0241) as shown in Figure 2. The difference in TLF was driven by a higher rate of TLR in Group 1b (8.6% vs. 3.7% vs. 4.4% vs. 4.9%; p=0.016).
Conclusion
In an all-comers population undergoing PCI with implantation of contemporary DES, a stent length ≥49mm and a stent diameter ≤2.5mm were associated with a higher rate of TLF after three years.

Abstract
Background: The prognostic value of the fibrinogen to albumin ratio on intrahospital mortality has been investigated in patients with cardiovascular disease, cancer, sepsis, and ischemic stroke; however, it has not been investigated for neurosurgical patients with spontaneous intracerebral hemorrhage (ICH). The present study investigates the impact of the fibrinogen to albumin ratio upon admission for intrahospital mortality in neurosurgical intensive care unit (ICU) patients with spontaneous ICH. Methods: A total of 198 patients with diagnosis of spontaneous ICH treated from 10/2008 to 12/2017 at our ICU were retrospectively analyzed. Blood samples were drawn upon admission, and the patients’ demographic, medical data, and cranial imaging were collected. Binary logistic regression analysis was performed to identify independent prognostic factors for intrahospital mortality. Results: The total rate of intrahospital mortality was 35.4% (n = 70). In the multivariate regression analysis, higher fibrinogen to albumin ratio (OR = 1.16, CI = 1.02−1.31, p = 0.03) upon admission was an independent predictor of intrahospital mortality in neurosurgical ICU patients with ICH. Moreover, a fibrinogen to albumin ratio cut-off level of >0.075 was related to increased intrahospital mortality (Youden’s index = 0.26, sensitivity = 0.51, specificity = 0.77). Conclusion: A fibrinogen to albumin ratio > 0.075 was significantly associated with increased intrahospital mortality in ICH patients.

Abstract
PURPOSE Purpose of this study was to investigate overall survival in recurrent glioblastoma treated with either carbon ion reirradiation or photon reirradiation. MATERIALS AND METHODS In this retrospective study we evaluated 78 consecutive patients with recurrent IDH (Isocitrate dehydrogenase)-wildtype glioblastoma (38 patients carbon ion re-radiotherapy, 40 patients photon re-radiotherapy) treated with either carbon ion reirradiation or stereotactic photon reirradiation. 45 Gy (RBE; 15 fractions) carbon ion reirradiation (CIRT) or 39 Gy (13 fractions) photon reirradiation (FSRT) was administered, respectively. Overall survival was investigated with respect to histological, clinical, and epidemiological features. Kaplan-Meier and multivariate Cox statistics were calculated. A propensity score-matched analysis of the FSRT and CIRT groups using variables from a validated prognosis score was carried out. RESULTS The type of reirradiation (CIRT vs. FSRT) significantly influenced overall survival-8.0 months vs. 6.5 months (univariate: p = 0.046)-and remained an independent prognostic factor in multivariate analysis (p = 0.017). Propensity score-adjusted analysis with CIRT versus FSRT as the dependent variable yielded a significant overall survival advantage for the CIRT group (median OS 8.9 versus 7.2 months, p = 0.041, 1‑year survival 29 versus 10%). Adverse events (AE) were evaluated for both subgroups. For the FSRT group no toxicity ≥ grade 4 occurred. For the CIRT subgroup no grade 5 AE occurred, but 1 patient developed a grade 4 radionecrosis. We encountered 4 grade 3 toxicities. One patient developed a zoster at the trunk, 2 progressed in their paresis, and 1 featured progressive dysesthesia. CONCLUSION In conclusion, carbon ion treatment is a safe and feasible treatment option for recurrent glioblastoma. Due to the retrospective nature of the study and two different dose levels for CIRT or FSRT, the improved outcome in CIRT reirradiation might be an effect of higher biological impact from carbon ions or a simple dose-escalation effect. This hypothesis needs prospective testing in larger patient cohorts. A prospective phase III randomized trial is in preparation at our center.

Abstract
Aims Intrahepatic biliary stones (hepatolithiasis) are not well characterised in patients with primary sclerosing cholangitis (PSC). Methods Chart reviews were conducted on 302 patients with a histologic or radiographic diagnosis of PSC followed at the Toronto Centre for Liver Disease. Radiographic data were collected for patients between the years 2008–2018. Depending on frequency of testing, magnetic resonance imaging (MRI) and ultrasound (US) data was reviewed every 3–5 years. We assessed factors associated with hepatolithiasis based on sex, race, age and phenotype of PSC and inflammatory bowel disease (IBD). Qualitative radiographic findings on image report review, episodes of cholangitis, endoscopic retrograde cholangiopancreatography (ERCP) and occurrence of cholangiocarcinoma (CCA), death and transplant were documented. Data are reported with median and IQR and analysed using χ 2 and Mann-Whitney U tests. Results 302 patients were reviewed. The median time to follow-up, defined as from date of diagnosis to last clinic visit or to transplantation date, was 98 months (IQR = 87). The mean age at diagnosis was 38 (SD = 15.1) years; 54% of patients were male. A total of 224 patients had IBD (74%). Of the 302 patients, 80 patients (26%) had evidence of hepatolithiasis on US or MRI. Patients with hepatolithiasis were more likely to be younger (37.4 vs 39.1, p = 0.025), male (65% vs. 50%, p = 0.021), and have large duct disease (99% vs. 88%, p = 0.004). Imaging report review revealed patients with hepatolithiasis were more likely to have intrahepatic biliary thickening (76% vs. 45%, p < 0.001), extrahepatic biliary thickening (69% vs. 50%, p = 0.003), focal biliary dilation (96% vs. 78%, p < 0.001) and disease characterised by more reported strictures on qualitative imaging report review (89% vs 69%, p < 0.001). Concomitant presence of cholelithiasis was greater in the hepatolithiasis vs. the non-hepatolithiasis group (45% vs. 19%, p < 0.001). There was no significant difference in the prevalence of hepatic or portal venous thrombosis in both groups. Patients with hepatolithiasis more likely have experienced acute ascending cholangitis (50% vs. 20%, p < 0.001) and need for ERCP (50% vs. 35%, p = 0.020). CCA was numerically higher in the hepatolithiasis group (8.75% vs. 4%, p = 0.1). Patients with hepatolithiasis received transplant more frequently (26.3% vs 12.2%, p < 0.001) with no significant difference in mortality. Conclusions Hepatolithiasis is common in PSC and associated with an increased clinical and radiologic disease burden. ![]()

Abstract
Oligodendrogliomas are defined at the molecular level by the presence of an IDH mutation and codeletion of chromosomal arms 1p and 19q. In the past, case reports and small studies described gliomas with sarcomatous features arising from oligodendrogliomas, so called oligosarcomas. Here, we report a series of 24 IDH-mutant oligosarcomas from 23 patients forming a distinct methylation class. The tumors were recurrences from prior oligodendrogliomas or developed de novo. Precursor tumors of 12 oligosarcomas were histologically and molecularly indistinguishable from conventional oligodendrogliomas. Oligosarcoma tumor cells were embedded in a dense network of reticulin fibers, frequently showing p53 accumulation, positivity for SMA and CALD1, loss of OLIG2 and gain of H3K27 trimethylation (H3K27me3) as compared to primary lesions. In 5 oligosarcomas no 1p/19q codeletion was detectable, although it was present in the primary lesions. Copy number neutral LOH was determined as underlying mechanism. Oligosarcomas harbored an increased chromosomal copy number variation load with frequent CDKN2A/B deletions. Proteomic profiling demonstrated oligosarcomas to be highly distinct from conventional CNS WHO grade 3 oligodendrogliomas with consistent evidence for a smooth muscle differentiation. Expression of several tumor suppressors was reduced with NF1 being lost frequently. In contrast, oncogenic YAP1 was aberrantly overexpressed in oligosarcomas. Panel sequencing revealed mutations in NF1 and TP53 along with IDH1/2 and TERT promoter mutations. Survival of patients was significantly poorer for oligosarcomas as first recurrence than for grade 3 oligodendrogliomas as first recurrence. These results establish oligosarcomas as a distinct group of IDH-mutant gliomas differing from conventional oligodendrogliomas on the histologic, epigenetic, proteomic, molecular and clinical level. The diagnosis can be based on the combined presence of (a) sarcomatous histology, (b) IDH-mutation and (c) TERT promoter mutation and/or 1p/19q codeletion, or, in unresolved cases, on its characteristic DNA methylation profile.

Abstract
PURPOSE Meningiomas are the most frequent primary intracranial tumors. Patient outcome varies widely from benign to highly aggressive, ultimately fatal courses. Reliable identification of risk of progression for individual patients is of pivotal importance. However, only biomarkers for highly aggressive tumors are established (CDKN2A/B and TERT), whereas no molecularly based stratification exists for the broad spectrum of patients with low- and intermediate-risk meningioma. METHODS DNA methylation data and copy-number information were generated for 3,031 meningiomas (2,868 patients), and mutation data for 858 samples. DNA methylation subgroups, copy-number variations (CNVs), mutations, and WHO grading were analyzed. Prediction power for outcome was assessed in a retrospective cohort of 514 patients, validated on a retrospective cohort of 184, and on a prospective cohort of 287 multicenter cases. RESULTS Both CNV- and methylation family-based subgrouping independently resulted in increased prediction accuracy of risk of recurrence compared with the WHO classification (c-indexes WHO 2016, CNV, and methylation family 0.699, 0.706, and 0.721, respectively). Merging all risk stratification approaches into an integrated molecular-morphologic score resulted in further substantial increase in accuracy (c-index 0.744). This integrated score consistently provided superior accuracy in all three cohorts, significantly outperforming WHO grading (c-index difference P = .005). Besides the overall stratification advantage, the integrated score separates more precisely for risk of progression at the diagnostically challenging interface of WHO grade 1 and grade 2 tumors (hazard ratio 4.34 [2.48-7.57] and 3.34 [1.28-8.72] retrospective and prospective validation cohorts, respectively). CONCLUSION Merging these layers of histologic and molecular data into an integrated, three-tiered score significantly improves the precision in meningioma stratification. Implementation into diagnostic routine informs clinical decision making for patients with meningioma on the basis of robust outcome prediction.

Abstract
Abstract
OBJECTIVE
Combination therapy, a treatment modality that combines two or more therapeutic agents, is a cornerstone of cancer therapy. The optimal combination therapy for Tumor Treating Fields (TTFields) in glioblastoma (GBM) treatment is unknown. The aim of our study was to analyze, the effects of the TERT-inhibitor eribulin in combination with TTFields on human GBM cells.
METHODS
Human GBM cells of the established cell lines U87, A172 and U251, and two patient-derived cell lines, were treated with eribulin monotherapy, TTFields monotherapy, or both modalities together. After 72 hours of therapy, cell counts were measured and clonogenic assays were performed. Annexin staining and fluorescence-activated cell scanning (FACS) was used to analyze cell death.
RESULTS
Overall surviving fractions were 39.8±11.0% for eribulin monotherapy, 32.2±23.9% for TTFields monotherapy, and 10.9±9.9% for the combined treatment. Mean observed annexin positive fractions were 11.2±8.2% (control), 28.6±9.7% (eribulin), 34.8±8.1% (TTFields), and 78.1±13.5% (combination), respectively. The mean clonogenic fractions over all cell lines were 25.9±7.8% for eribulin and 46.4±12.9% for TTFields. For the combination therapy, a synergistic effect with a decreased mean of 3.6% clonogenic fractions was observed.
CONCLUSION
Eribulin increases cell death and reduces clonogenicity our experiments. Additionally, a synergistic effect of the combined treatment of TTFields and eribulin synergistic was observed. Eribulin in combination with TTFields could be a new effective therapy for GBM.

Abstract
Abstract
PURPOSE
Meningiomas are the most frequent primary intracranial tumors. Patient outcome varies widely from cases with benign to highly aggressive, ultimately fatal courses. Reliable identification of risk of progression for the individual patient is of pivotal importance in clinical management. However, only biomarkers for highly aggressive tumors are established at present (CDKN2A/B and TERT), while no molecularly-based stratification exists for the broad spectrum of low- and intermediate-risk meningioma patients.
PATIENTS AND METHODS
DNA methylation data and copy-number information were generated for 3,031 meningiomas of 2,868 individual patients, with mutation data for 858 samples. DNA methylation subgroups, copy-number variations (CNV), mutations and WHO grading were comparatively analyzed. Prediction power for outcome of these parameters was assessed in an initial retrospective cohort of 514 patients, and validated on a retrospective cohort of 184, and on a prospective cohort of 287 multi-center cases, respectively.
RESULTS
Both CNV and methylation family- (MF)-based subgrouping independently resulted in an increase in prediction accuracy of risk of recurrence compared to the WHO classification (c-indexes WHO 2016, CNV, and MF 0.699, 0.706 and 0.721, respectively). Merging all independently powerful risk stratification approaches into an integrated molecular-morphological score resulted in a further, substantial increase in accuracy (c-index 0.744). This integrated score consistently provided superior accuracy in all three cohorts, significantly outperforming WHO grading (c-index difference p=0.005). Besides the overall stratification advantage, the integrated score separates more precisely for risk of progression at the diagnostically challenging interface of WHO grade 1 and grade 2 tumors (HR 4.56 [2.97;7.00], 4.34 [2.48;7.57] and 3.34 [1.28; 8.72] for discovery, retrospective, and prospective validation cohort, respectively).
CONCLUSIONS
Merging these layers of histological and molecular data into an integrated, three-tiered score significantly improves the precision in meningioma stratification. Implementation into diagnostic routine informs clinical decision-making for meningioma patients on the basis of robust outcome prediction.

Abstract
Abstract
Background
The COVID-19 pandemic demonstrated the need for better pandemic preparedness and response, and more international collaboration. The H2020 EU-funded PANDEM-2 project aims to prepare Europe for future pandemics. As part of the project, an European dashboard consisting of epidemiological data and insights on available pandemic health care capacity is developed. To model and map the availability of pandemic resources, data on the use of these resources and interdependencies between resources are needed to parametrize the resource model of the PANDEM-2 dashboard.
Methods
We conduct a systematic literature review. The database Embase.com was searched on articles that include a model, scenario, or simulation of pandemic resources and/or describe resource parameters, for example PPE usage, length of stay on the ICU, or vaccine efficacy. Our search included data from all continents and focuses on infectious diseases that have been declared a pandemic by the WHO in the last twenty years, which are the H1N1 influenza (2009-2010) and COVID-19 (ongoing).
Preliminary results
The search query and additional sources resulted in 1215 articles, of which 187 are included for the full text eligibility assessment. We identified several pandemic resources in the field of vaccination (vaccine efficacy), contact tracing (apps), general practitioners, the hospital (staff, PPE, ventilators), and national and regional public health institutes. Furthermore, interdependencies between resources and possible resource gaps were found, for example in hospital staff and PPE.
Conclusions
To be better prepared and to be able to respond fast to a pandemic outbreak, it is important to have insight in the availability of pandemic resources on a national and regional level, their use and mutual dependencies. This makes it possible to anticipate on fast changes and possible shortages by reallocating resources within and between regions.

Abstract
BACKGROUND Many patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) are discharged without a known aetiology for their clinical presentation. This study sought to assess the effect of this 'indeterminate MINOCA' diagnosis on the prevalence of recurrent cardiovascular events and presentations to the Cardiac Emergency Department (CED). METHODS We retrospectively analysed all patients meeting the diagnostic MINOCA criteria presenting at a large secondary hospital between January 2017 and April 2019. PARTICIPANTS Patients were divided into the (1) 'indeterminate MINOCA', or (2) 'MINOCA with diagnosis' group. The primary outcome was the occurrence of major adverse cardiac events (MACE) defined as the composite of all-cause mortality, non-fatal myocardial infarction, stroke and any revascularisation procedure. Secondary outcomes were all recurrent visits at the CED, and MACE including unplanned cardiac hospitalisation. RESULTS In 62/198 (31.3%) MINOCA patients, a conclusive diagnosis was found (myocardial infarction, (peri)myocarditis, cardiomyopathy, or miscellaneous). MINOCA patients with a confirmed diagnosis were younger compared to those with an indeterminate diagnosis (56.7 vs. 62.3 years, p = 0.007), had higher maximum troponin-T [238 ng/L vs. 69 ng/L, p < 0.001] and creatine kinase (CK) levels [212U/L vs. 152U/L, p = 0.007], and presented more frequently with electrocardiographic signs of ischaemia (71.0% vs. 47.1%, p = 0.002). Indeterminate MINOCA patients more often showed recurrent CED presentations (36.8% vs. 22.6%, p = 0.048), however the occurrence of cardiovascular events was equal (8.8 vs. 8.1%, p = 0.86). Multivariable analysis showed that elevated levels of troponin-T and CK, ST-segment deviation on electrocardiography, reduced left ventricular ejection fraction, regional wall motion abnormalities, and performance of additional examination methods were independent predictors for finding the underlying MINOCA cause. CONCLUSIONS Only in one-third of MINOCA patients a conclusive diagnosis for the acute presentation was identified. Recurrent CED visits were more often observed in the indeterminate MINOCA group, while the occurrence of cardiovascular events was similar across groups. TRIAL REGISTRATION Retrospectively registered.

Abstract
OBJECTIVE The aim of this work is to define competencies and entrustable professional activities (EPAs) to be imparted within the framework of surgical neuro-oncological residency and fellowship training as well as the education of medical students. Improved and specific training in surgical neuro-oncology promotes neuro-oncological expertise, quality of surgical neuro-oncological treatment and may also contribute to further development of neuro-oncological techniques and treatment protocols. Specific curricula for a surgical neuro-oncologic education have not yet been established. METHODS We used a consensus-building approach to propose skills, competencies and EPAs to be imparted within the framework of surgical neuro-oncological training. We developed competencies and EPAs suitable for training in surgical neuro-oncology. RESULT In total, 70 competencies and 8 EPAs for training in surgical neuro-oncology were proposed. EPAs were defined for the management of the deteriorating patient, the management of patients with the diagnosis of a brain tumour, tumour-based resections, function-based surgical resections of brain tumours, the postoperative management of patients, the collaboration as a member of an interdisciplinary and/or -professional team and finally for the care of palliative and dying patients and their families. CONCLUSIONS AND RELEVANCE The present work should subsequently initiate a discussion about the proposed competencies and EPAs and, together with the following discussion, contribute to the creation of new training concepts in surgical neuro-oncology.

Abstract
OBJECTIVES The aim of this study was to examine whether associations between disease severity and packed cell volume exist in dogs with myxomatous mitral valve disease. MATERIALS AND METHODS Data were selected from 289 dogs that had been examined at a research clinic (2004-2017) on multiple occasions (n=1465). American College of Veterinary Internal Medicine stage and echocardiographic measurements were entered in separate multivariable linear mixed effects models with packed cell volume as the dependent variable. Age, breed, sex, weight and blood urea nitrogen concentrations were additionally tested in these analyses to control for patient characteristics. RESULTS Packed cell volume (% whole blood) in stages B1 and B2 (B1: 42.62 ±0.27, P=0.001; B2: 41.77± 0.42, P < 0.001) was lower than stage A (44.57 ±0.53). In stage C, packed cell volume was greater than both preclinical stages (C: 43.84 ±0.46). When the administration of loop diuretics was included in statistical models, packed cell volume was inversely related to normalised left ventricular internal diameters (β: -2.37; 95% confidence intervals: -3.49, -1.25; P < 0.001). CLINICAL SIGNIFICANCE Dogs with myxomatous mitral valve disease may develop reductions in packed cell volume as their disease progresses. Although this finding was statistically significant at a population level, it should be noted that the differences described are relatively small. This, along with other causes of variation in packed cell volume, means that changes would be challenging to appreciate within individual patients. Plasma volume depletion following diuretic administration may explain why findings differed in stage C.

Abstract
Background In the region of South Limburg, the Netherlands, a shared ST-elevation myocardial infarction (STEMI) networking system (SLIM network) was implemented. During out-of-office hours, two percutaneous coronary intervention (PCI) centres—Maastricht University Medical Centre and Zuyderland Medical Centre—are supported by the same interventional cardiologist. The aim of this study was to analyse performance indicators within this network and to compare them with contemporary European Society of Cardiology guidelines. Methods Key time indicators for an all-comer STEMI population were registered by the emergency medical service and the PCI centres. The time measurements showed a non-Gaussian distribution; they are presented as median with 25th and 75th percentiles. Results Between 1 February 2018 and 31 March 2019, a total of 570 STEMI patients were admitted to the participating centres. The total system delay (from emergency call to needle time) was 65 min (53–77), with a prehospital system delay of 40 min (34–47) and a door-to-needle time of 22 min (15–34). Compared with in-office hours, out-of-office hours significantly lengthened system delays (55 (47–66) vs 70 min (62–81), p < 0.001), emergency medical service transport times (29 (24–34) vs 35 min (29–40), p < 0.001) and door-to-needle times (17 (14–26) vs 26 min (18–37), p < 0.001). Conclusions With its effective patient pathway management, the SLIM network was able to meet the quality criteria set by contemporary European revascularisation guidelines.

Abstract
OBJECTIVE Peripheral nerve field stimulation (PNFS) is an effective alternative treatment for patients with chronic low back pain. The treatment of low back pain strongly depends on psychological factors like anxiety, depression, and mental stress. The aim of this study was to evaluate the impact of such factors on outcome measures after lead- and implantable pulse generator-implantation. MATERIALS AND METHODS Between 2014 and 2019, a prospective cohort study of 39 patients with chronic lumbar pain was conducted. Hospital Anxiety and Depression Scale (HADS) score was assessed at baseline to measure symptoms of anxiety and depression. Symptom checklist-90 (SCL-90) was used to measure subjective psychopathology. Pain intensity (numeric pain rating scale [NRS]), SF12v2 with Physical Component Summary and Mental Component Summary (MCS) scores, and Oswestry Disability Index (ODI) were assessed pre- and postoperatively as well as three and six months after PNFS implantation. Outcome values were compared to baseline data. Statistical analysis was performed using depending t-test and analysis of variance (ANOVA). A p value <0.05 was considered significant. RESULTS The cohort consisted of 39 patients (18 females, 21 males) with a median age of 61 years (IQR25-75 = 52-67 years). NRS, ODI, and SF12v2 showed significant improvement in the whole follow-up period compared to baseline values (p < 0.05). Elevated HADS scores for anxiety were seen in 64.1%, for depression in 76.9% of the patients at baseline. SCL-90 was pathologic in 71.8% of the cases. A one-way ANOVA revealed no differences between elevated HADS- and SCL-90 values and all outcome measures after PNFS implantation in the whole follow-up period (p > 0.05). CONCLUSION Chronic low back pain is often associated with psychological distress. Our study showed highly elevated levels for anxiety and depression as well as subjective mental stress in patients with chronic low back pain without negative impact on NRS, ODI, and SF12v2 in the whole follow-up after PNFS implantation.

Abstract
BACKGROUND The prognostic significance of serum biomarkers in patients with intracerebral hemorrhage (ICH) is not well investigated concerning inhospital mortality (IHM) and cardiopulmonary events within the first 24 hours of intensive care unit (ICU) treatment. The influence of troponin I (TNI) value and cortisol value (CV) on cardiopulmonary events within the first 24 hours of ICU treatment was reported in subarachnoid hemorrhage patients, but not in ICH patients up to now. The aim of this study was to investigate the role of early serum biomarkers on IHM and TNI value and CV on cardiopulmonary events within the first 24 hours of ICU treatment. PATIENTS AND METHODS A total of 329 patients with spontaneous ICH were retrospectively analyzed. Blood samples were taken on admission to measure serum biomarkers. The TNI value and CV were defined as biomarkers for cardiopulmonary stress. Demographic data, cardiopulmonary parameters, including norepinephrine application rate (NAR) in microgram per kilogram per minute and inspiratory oxygen fraction (FiO2) within the first 24 hours, and treatment regime were analyzed concerning their impact on ICU treatment and in hospital outcome. Binary logistic analysis was used to identify independent prognostic factors for IHM. RESULTS Patients with initially nonelevated CVs required higher NAR (p = 0.01) and FiO2 (p = 0.046) within the first 24 hours of ICU treatment. Lower cholinesterase level (p = 0.004), higher NAR (p = 0.002), advanced age (p < 0.0001), larger ICH volume (p < 0.0001), presence of intraventricular hemorrhage (p = 0.007) and hydrocephalus (p = 0.009), raised level of C-reactive protein (p = 0.024), serum lactate (p = 0.003), and blood glucose (p = 0.05) on admission were significantly associated with IHM. In a multivariate model, age (odds ratio [OR]: 1.055; 95% confidence interval [CI]: 1.026-1.085; p < 0.0001), ICH volume (OR: 1.016; CI: 1.008-1.025; p < 0.0001), and Glasgow Coma Scale (GCS) score (OR: 0.680; CI: 0.605-0.764; p < 0.0001) on admission as well as requiring NAR (OR: 1.171; CI: 1.026-1.337; p = 0.02) and FiO2 (OR: 0.951; CI: 0.921-0.983, p = 0.003) within the first 24 hours were independent predictors of IHM. CONCLUSION Higher levels of C-reactive protein, serum lactate, blood glucose, and lower cholinesterase level on admission were significantly associated with IHM. Patients with initially nonelevated CVs required higher NAR and FiO2 within the first 24 hours of ICU treatment. Furthermore, requiring an NAR > 0.5 µg/kg/min or an FiO2 > 0.21 were identified as additional independent predictors for IHM. These results could be helpful to improve ICU treatment in ICH patients.

Abstract
Abstract
BACKGROUND
Tumor treating fields (TTFields) are an approved glioblastoma (GBM) treatment modality that demonstrated a significant improved median overall survival in newly diagnosed GBM patients. Data about morphologic changes in serial magnetic resonance imaging (MRI) for patients with a combination therapy of TTFields and proton boost therapy does not exist.
METHODS
Twenty-two patients were included in this study. All patients were treated with initial tumor resection followed by combined chemo- and radiation therapy. Radiation therapy was performed with 50.0 Gy photons and a proton boost with 10 Gy equivalent (Gy(RBE)). 11 patients were additionally treated with TTFields.
RESULTS
A new increase in contrast enhancement and/or a progress in the T2 FLAIR hyperintensity was observed in 54.5% (N=12) at 3 months and in 31.8% (N=7) at 6 months. No differences were observed between patients with and without TTFields therapy at 3 months [63.6% (N=7) vs. 45.5% (N=5); P=0.392] and at 6 months [27.3 (N=3) vs. 36.3% (N=4); P=0.647). By the RANO criteria a progressive disease (PD) was observed in 6 patients (27.3%) at 3 months and in 7 patients (31.8%) at 6 months. Pseudoprogression (PP) was observed in in 36.4% (N=8) at months and in 27.3% (N=6) at 6 months. Neither for PD at 3 months [36.4% (N=4) vs. 18.2% (N=2); P=0.338] or at 6 months [36.4% (N=4) vs. 27.3% (N=3); P=0.647), nor for PP at 3 months [45.5% (N=5) vs. 27.2% (N=3); P=0.375] or at 6 months [18.2% (N=2) vs. 36.4% (N=4); P=0.338] differences for patients with and without TTFields therapy were found.
CONCLUSION
Increased contrast enhancement and/or increased T2 FLAIR MRI hyperintensity after proton boost therapy are common. Furthermore, the rates for new contrast enhancement, PD, and PP after photon therapy with and without additional TTFields therapy are comparable.

Abstract
Sphingosine‑1‑phosphate (S1P) plays a key role in cell survival, growth, migration, and in angiogenesis. In glioma, it triggers the activity of the S1P‑receptor 1 and of the sphingosine kinase 1; thus influencing the survival rate of patients. The aim of the present study was to investigate the anti‑proliferative effect of the S1P analogue FTY720 (fingolimod) in glioblastoma (GBM) cells. A172, G28, and U87 cells were incubated with micromolar concentrations of FTY720 or temozolomide (TMZ) for 24 to 72 h. Proliferation and half maximal inhibitory concentration (IC50) were determined by using the xCELLigence system. FACS analysis was performed to check the cell cycle distribution of the cells after a 72‑h incubation with FTY720. This was then compared to TMZ‑incubated and to untreated cells. Gene expression was detected by RT‑qPCR in A172, G28, U87 and three primary GBM‑derived cell lines. FTY720 was able to reduce the number of viable cells. The IC50 value was 4.6 µM in A172 cells, 17.3 µM in G28 cells, and 25.2 µM in U87 cells. FTY720 caused a significant arrest of the cell cycle in all cells and stabilized or over‑expressed the level of AKT1, MAPK1, PKCE, RAC1, and ROCK1 transcripts. The TP53 transcript level remained stable or was downregulated after treatment with FTY720. FTY720 may be a promising target drug for the treatment of GBM, as it has a strong anti‑proliferative effect on GBM cells.

Abstract
Background Multiple scores have been proposed to guide risk stratification after percutaneous coronary intervention. This study assessed the performance of the PRECISE-DAPT, PARIS and CREDO-Kyoto risk scores to predict post-discharge ischaemic or bleeding events. Methods A total of 1491 patients treated with latest-generation drug-eluting stent implantation were evaluated. Risk scores for post-discharge ischaemic or bleeding events were calculated and directly compared. Prognostic performance of both risk scores was assessed with calibration, Harrell’s c‑statistics net reclassification index and decision curve analyses. Results Post-discharge ischaemic events occurred in 56 patients (3.8%) and post-discharge bleeding events in 34 patients (2.3%) within the first year after the invasive procedure. C‑statistics for the PARIS ischaemic risk score was marginal (0.59, 95% confidence interval (CI) 0.51–0.68), whereas the CREDO-Kyoto ischaemic risk score was moderate (0.68, 95% CI 0.60–0.75). With regard to post-discharge bleeding events, CREDO-Kyoto displayed moderate discrimination (c-statistic 0.67, 95% CI 0.56–0.77), whereas PRECISE-DAPT (0.59, 95% CI 0.48–0.69) and PARIS (0.55, 95% CI 0.44–0.65) had a marginal discriminative capacity. Net reclassification index and decision curve analysis favoured CREDO-Kyoto-derived bleeding risk assessment. Conclusion In this contemporary all-comer population, PARIS and PRECISE-DAPT risk scores were not resilient to independent testing for post-discharge bleeding events. CREDO-Kyoto-derived risk stratification was associated with a moderate predictive capability for post-discharge ischaemic or bleeding events. Future studies are warranted to improve risk stratification with more focus on robustness and rigorous testing.

Abstract
OBJECTIVE Peripheral nerve field stimulation (PNFS) is an effective alternative treatment for patients with chronic low back pain. Transcutaneous electrical nerve stimulation (TENS) is frequently used in pain therapy. Aim of this prospective study was to examine the predictive value of TENS for later PNFS treatment. MATERIALS AND METHODS Between 2014 and 2019, a prospective cohort study of 41 patients with chronic lumbar pain was conducted. Pain intensity (NRS) was assessed before and after TENS use, preoperatively/postoperatively and in the follow-up after three and six months, SF12v2 questionnaires with physical (PCS) and mental component summary (MCS) scores, and Oswestry disability index (ODI) questionnaire at baseline as well as three and six months after PNFS implantation. Implantation of the PNFS-system with two percutaneous leads was performed after four to seven days of positive testing. Statistical analysis was performed using depending t-test, ANOVA, and Spearman correlation. RESULTS The cohort consisted of 41 patients (19 females, 22 males) with a median age of 60.5 years (IQR25-75 52-67). Two patients were lost to follow-up. After positive PNFS testing a pulse generator (IPG) was implanted in 15 patients with positive TENS effect and 15 patients without TENS effect. Leads were explanted in nine patients after negative PNFS trial phase. TENS positive patients showed significant correlation to a positive effect in the PNFS trial phase in NRS reduction (p = 0.042) indicating that TENS responders will also respond to PNFS (94% patients). After three and six months follow-up median NRS and SF12v2 (PCS) improved significantly in both cohorts, SF12v2 (MCS) and ODI only in the TENS positive cohort, respectively. CONCLUSION TENS can be predictive for patient selection in PNFS, as TENS positive patients showed significant correlation with a positive PNFS trial period. Therefore, TENS positive patients might be justifiable to be directly implanted with leads and IPG. TENS positive patients further tend to show a better improvement in the follow-up.

Abstract
Abstract
Introduction
Perspectives on co-sleeping vary by family cultural background and socio-demographic characteristics; furthermore, families may choose to co-sleep based on family values or out of necessity. To better understand the role of co-sleeping in young children from ethnic minority backgrounds, the current study sought to test the relationship between co-sleeping and sleep outcomes in an urban early childhood setting.
Methods
141 Parent-child dyads with children aged 1-5 years old (N=141,50.4% female, M=4.01 [SD=1.05]; 41% African American; 41% Latinx; median income $20-30,000) were recruited through an urban preschool. Parents completed demographic information and the Brief Child Sleep Questionnaire, which yielded insomnia and sleep hygiene indices. Step-wise regressions were used to examine the relationship between sleeping location and sleep outcomes (insomnia, sleep health, and child sleep quality), controlling for child age.
Results
Approximately half of the sample (n=71) reported that their child sleeps in a space shared by caregivers or siblings. Co-sleeping did not differ by race/ethnicity [χ 2(3)=1.45, p=.694], child age [F(1, 140)=2.15, p=.145], or income [χ 2(5)=7.05, p=.217]. Controlling for age, insomnia was higher in co-sleeping children [F(2,140)=4.10, p=.019], although sleep location was not a significant independent predictor. Sleep hygiene [F(2,140)=2.39, p=.095] and sleep quality [F(2,139)=0.94, p=.394] did not differ by sleeping location, when controlling for age.
Conclusion
Co-sleeping was common but was not related to sociodemographic factors as described in prior research. Controlling for age, co-sleeping predicted higher insomnia scores suggesting that co-sleeping may be related to symptoms of behavioral insomnia. Sleep hygiene practices and sleep quality did not differ by sleeping location, suggesting that in children without behavioral insomnia symptoms, co-sleeping may not affect sleep. Future studies that seek to better understand caregiver preference and intentions regarding co-sleeping may be important to intervention development seeking to improve behavioral insomnia in ethnic/minority samples.

Abstract
OBJECTIVE Cardiopulmonary (CP) complications are well-known phenomena after an isolated traumatic brain injury (iTBI) and they may be associated with an elevated serum troponin I (TnI) value. However, the influence of an elevated TnI level on CP parameters within the first 24 h after an iTBI is still unknown. The current study was conducted to assess the associations between the initial TnI value on admission and CP parameters during the first 24 h of intensive care unit (ICU) treatment in iTBI patients. PATIENTS AND METHODS A total of 288 patients with iTBIs, who were admitted to our emergency department between January 2010 and November 2016 were retrospectively analyzed. Blood samples were taken on admission to determine TnI value. Each patient's demographic data, treatment regime, computed tomography results, and intra-hospital outcomes were evaluated, as well as several CP parameters, within the first 24 h of ICU treatment. The entire study population was stratified into patients with an initial TnI elevation (TnI positive) and without an initial TnI elevation (TnI negative). RESULTS Increased TnI values on admission were found in 59 (20.5%) patients. There were significant correlations between an initially elevated TnI value and a lower Glasgow Coma Scale score (p = 0.003), higher head Abbreviated Injury Scale score (p<0.0001), and higher Acute Physiology and Chronic Health Evaluation II score (p = 0.005) on admission, as well as a lower Glasgow Outcome Scale score (p = 0.0002) and higher modified Rankin Scale score (p = 0.0001) at discharge. In addition, a significantly higher norepinephrine application rate (NAR) (p<0.0001) and inspiratory oxygen fraction (FiO2) (p = 0.028) were needed in the TnI positive group. CONCLUSION Patients with elevated TnI values on admission require more circulation support (NAR and FiO2) within the first 24 h of ICU treatment after an iTBI. Therefore, the TnI may be a useful biomarker to improve ICU treatment of these patients.

Abstract
Objective: The impact of increased C-reactive protein (CRP)/albumin ratio on intra-hospital mortality has been investigated among patients admitted to general intensive care units (ICU). However, it was not investigated among patients with spontaneous intracerebral hemorrhage (ICH). This study aimed to investigate the impact of CRP/albumin ratio on intra-hospital mortality in patients with ICH. Patients and Methods: This retrospective study was conducted on 379 ICH patients admitted between 02/2008 and 12/2017. Blood samples were drawn upon admission and the patients’ demographic, medical, and radiological data were collected. The identification of the independent prognostic factors for intra-hospital mortality was calculated using binary logistic regression and COX regression analysis. Results: Multivariate regression analysis shows that higher CRP/albumin ratio (odds ratio (OR) = 1.66, 95% confidence interval (CI) = 1.193–2.317, p = 0.003) upon admission is an independent predictor of intra-hospital mortality. Multivariate Cox regression analysis indicated that an increase of 1 in the CRP/albumin ratio was associated with a 15.3% increase in the risk of intra-hospital mortality (hazard ratio = 1.153, 95% CI = 1.005–1.322, p = 0.42). Furthermore, a CRP/albumin ratio cut-off value greater than 1.22 was associated with increased intra-hospital mortality (Youden’s Index = 0.19, sensitivity = 28.8, specificity = 89.9, p = 0.007). Conclusions: A CRP/albumin ratio greater than 1.22 upon admission was significantly associated with intra-hospital mortality in the ICH patients.

Abstract
Glioblastoma (GBM) is the most common and aggressive primary brain tumor in adults. We present a case of a 42-year-old male patient presenting with headache and vomiting. Imaging demonstrated obstructive hydrocephalus and a ring-enhancing lesion in the right posterior thalamus. After endoscopic third ventriculostomy and stereotactic biopsy, the histopathologic diagnosis of a malignant glioma was confirmed by DNA methylation array as GBM isocitrate dehydrogenase wild type. The patient was treated with combined treatment of chemoradiation with temozolomide (TMZ) including proton boost, TMZ maintenance, and tumor-treating fields. In this case report, complete radiological response was observed 1 year after the end of radiation therapy.

Abstract
BACKGROUND Vasospasm, delayed ischemic neurologic deficit (DIND), and ischemic brain lesions after acute subarachnoid hemorrhage (SAH) are associated with increased morbidity and mortality. The purpose of this study was to analyze age cutoffs for vasospasm, DIND, and ischemic brain lesions after SAH. METHODS This study included 292 aneurysmal SAH patients from January 2005 to December 2015. Patients' data were extracted from a prospective database with measurements of transcranial Doppler sonography. Any vasospasm was defined as a maximum mean flow velocity (MMFV) >120 cm/sec. Severe vasospasms were defined as at least 2 measurements of MMFVs >200 cm/sec or an increase of MMFV >50 cm/sec/24 hours over 2 consecutive days or a new neurologic deficit. All MMFVs >120 cm/sec in absence of severe vasospasm criteria were defined as mild vasospasm. Age-related cutoff values were calculated using receiver operating curve analysis. RESULTS Any vasospasms occurred in 142 patients and thereof mild vasospasm in 86/142 (60.6%) patients and severe vasospasm in 56/142 patients (39.4%). Significantly higher incidences of any vasospasm (P = 0.005), severe vasospasm (P = 0.003), DIND (P = 0.031), and ischemic brain lesions (P = 0.04) were observed in patients aged <50 years. According to receiver operating curve analysis, the optimal age cutoff was 50 years for the presence of overall vasospasms, severe vasospasms, DIND, and ischemic brain lesions and 65 years for mild vasospasms. CONCLUSIONS Higher incidences of any vasospasms, severe vasospasms, DIND, and ischemic brain lesions were observed in younger SAH patients.

Abstract
BACKGROUND Risk factors for acute symptomatic seizures after stroke demonstrated in retrospective analyses should be confirmed in large population studies. While seizures following ischemic stroke have been studied intensively, less is known about seizure predictors in hemorrhagic stroke. This study sought to identify risk factors of acute symptomatic seizures and to elucidate associated short-term (in-hospital) morbidity and mortality rates in primary intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). METHODS We determined the frequency of all acute symptomatic seizures perceived by clinical staff after hemorrhagic stroke in a large population-based registry in a central European region between 2004 and 2016. Further, we analyzed risk factors for seizure occurrence, morbidity, and mortality in univariate and multivariate analyses. RESULTS Of 297,120 stroke patients, 19,331 experienced a hemorrhagic stroke. Frequency of acute seizures (without semiological differentiation) in this subpopulation was 4% (4.0% in ICH and 3.6% in SAH). The risk for acute symptomatic seizures was significantly increased in both stroke types in the presence of an acute non-neurological infection (odds ratio: 2.0 for ICH and 4.2 for SAH). A lower premorbid functional level also significantly increased the seizure risk (odds ratio: 2.0 for ICH and 3.1 for SAH). The odds of in-hospital mortality in the presence of acute seizures were significantly reduced in ICH patients (odds ratio: 0.7) but not in SAH patients. CONCLUSION Acute symptomatic seizures are equally common in ICH and SAH patients in this registry. Seizure risk is invariably increased in the presence of acute non-neurological infection. Mortality is reduced in ICH patients with seizures, but the exact reason for this relationship is not clear and might represent a biased finding.

Abstract
Background Patients with recurrent glioma after prior radiotherapy have a poor prognosis. Carbon ion beam radiotherapy offers highly conformal dose distributions and more complex biological radiation effects eventually resulting in optimized normal tissue sparing and improved outcome. The aim of this study was to analyze toxicity, local control and overall survival after reirradiation of recurrent high-grade glioma with carbon ion radiotherapy. Methods Between 10/2015 and 12/2018, 30 patients (median age: 59 years) with recurrent high-grade glioma were reirradiated with carbon ion beams and retrospectively analyzed. Diagnosis of recurrent glioma was based on magnetic resonance imaging. Thirteen patients had repeated resection prior to reirradiation and 24 patients underwent additional chemotherapy. The median initial radiation dose was 60 Gy and the median time interval between the initial and repeated radiotherapy was 10 months. The reirradiation dose was 45 Gy (relative biological effectiveness) applied in 15 fractions. All patients received regular follow-up imaging after reirradiation. Kaplan-Meier estimation, log rank test and Cox regression analysis were used for statistical assessment. Results Applying common toxicity criteria, there were no grade 5 or 4 adverse events, while 8 patients showed grade 3 adverse events. The median follow-up after reirradiation was 11 months and the median overall survival after diagnosis of recurrent high-grade glioma was 13 months. The 6-, 12- and 24-month overall survival rates after diagnosis of recurrent high-grade glioma were 76%, 50% and 19%, respectively. Upon multivariate Cox regression analysis, a Ki67 score of the initial tumor histology of less than 20% was prognostic. Repeated resection or chemotherapy for the recurrent disease did not result in significantly prolonged survival. Conclusion Carbon ion reirradiation in recurrent high-grade glioma is safe and feasible. No radiation-associated grade 4 toxicities were documented and treatment was tolerated well.

Abstract
OBJECTIVE Intrahospital transports (IHTs) of neurosurgical intensive care unit (NICU) patients can be hazardous. Increasing intracranial pressure (ICP) and/or decreasing cerebral perfusion pressure (CPP) as well as cardiopulmonary alterations are common complications of an IHTs, which can lead to secondary brain injury. This study was performed to assess several serum biomarkers concerning their potential to improve safety of IHTs in mechanically ventilated NICU patients. METHODS All IHTs of mechanically ventilated and sedated NICU patients from 03/2017 to 01/2018 were retrospectively analyzed. Intracranial pressure and CPP measurements were performed in all patients. Serum hemoglobin, hematocrit, and serum sodium were defined as serum biomarkers. Demographic data, computed tomography scan on admission, Simplified Acute Physiology Score and Acute Physiology and Chronic Health Evaluation II, modified Rankin Scale, indication and consequence of IHTs were analyzed. Alteration of ICP/CPP, hemodynamic and pulmonary events were defined as complications. The study population was stratified into patients with the occurrence of a complication and absence of a complication. RESULTS We analyzed a total number of 184 IHTs in 70 NICU patients with an overall complication rate of 57.6%. Of all, 32.1% IHTs had no direct therapeutic consequence. In patients with higher hemoglobin values prior to IHT less complications occurred, concerning ICP (P = .001), CPP (P = .001), hemodynamic (P = .005), and pulmonary (P < .0001) events. In addition, complications concerning ICP (P = .001), CPP (P = .001), hemodynamic (P = .005), and pulmonary problems (P = .002) were significantly lower in patients with higher hematocrit values before IHT. CONCLUSION Intrahospital transports of mechanically ventilated NICU patients carry a high risk of increased ICP and hemodynamic complications and should be performed restrictively. Higher values of hemoglobin and hematocrit prior to IHT were associated with less complications with regard to ICP, CPP as well as hemodynamic and pulmonary events and could be helpful to assess the potential risk of complications prior to IHTs.

Abstract
Abstract
Background and aims
Complex regional pain syndrome (CRPS) is a common pain condition which is characterized by pain, functional impairment, and trophic changes. Neurosurgical treatment is not widely offered. In this study the treatment with spinal cord stimulation (SCS) was evaluated over 24 months follow up.
Methods
A retrospective case analysis of six patients with severe CRPS was performed. Pain chronicity was recorded with the Mainz Pain Staging System (MPSS). Pain intensity (NRS), activity level and health-related quality of life (EQ-5D-5L), the actual mood state (ASTS), and treatment satisfaction (CSQ-8) were assessed. All patients received conventional pharmacological treatments including multimodal pain therapy through their local pain therapist or in specialized centers as well as physical therapy. A SCS electrode was implanted for trial stimulation. After successful trial a neurostimulator was implanted and connected to the electrode. Patients were retrospectively analyzed before implantation and 6, 12 and 24 months postoperatively. Statistical analysis was performed using Mann–Whitney U and Wilcoxon rank-sum test.
Results
Patients median age was 43 years (IQR25−75 37–43 years). The median MPSS Score was 3 of 3 indicating a high pain chronicity. Median NRS before implantation of the neurostimulator was 8.8 (IQR25−75 7.6–9.3). A reduction to 7.8 (IQR25−75 4.8–8.1; p = 0.14) after 6 months, 6.5 (IQR25−75 3.8–8.1; p = 0.08) after 1 year, and 6.8 (IQR25−75 3.8–8.5; p = 0.15) after 2 years was achieved. Median EQ-5D-5L index value before treatment was 0.27 (IQR25−75 0.25–0.41) indicating a severely lowered quality of life. A significant improvement to 0.53 (IQR25−75 0.26–0.65; p = 0.03) after 6 months, 0.58 (IQR25−75 0.26–0.84; p = 0.03) after 1 year as well as after 2 years was seen. ASTS scale showed an increase of values for positive mood, and a reduction in values for sorrow, fatigue, anger and desperation during the whole follow up period. The treatment satisfaction in the whole cohort with a median CSQ-8 value of 29.5 of 32 was very high.
Conclusion
The results of this small case series showed a significant improvement of the EQ-5D-5L after implantation of a neurostimulator. NRS reduction was not significant but a clear tendency towards reduced values was observed. We therefore conclude that SCS is an alternative option to relieve chronic pain and psychological distress originating from CRPS if non-invasive managements of severe CRPS failed. The preoperative selection plays a crucial role for good results.
Implications
CRPS is difficult to treat. SCS is an alternative option to improve the quality of life and relieve chronic pain originating from severe CRPS if conservative treatment modalities fail. Further psychological distress is reduced in long-term follow up. SCS should be kept in mind for therapy refractory cases.

Abstract
Abstract
BACKGROUND
Proton therapy is able to apply high radiation doses to the tumor while sparing healthy tissues by reducing integral dose. Tumor Treating Fields (TTFields) are low intensity (1–3 V/cm) and intermediate frequency (100–300 kHz) alternating electric fields that demonstrated significantly increased survival rates in combination with adjuvant temozolomide (TMZ) in patients with newly diagnosed glioblastoma (ndGBM). Here, we report on a patient with biopsied ndGBM IDH wildtype with complete radiological response.
MATERIAL AND METHODS
Brain MRI demonstrated an occlusive hydrocephalus and a ring enhancing lesion in the right posterior thalamus in a 42 year old male. After endoscopic ventriculostomy and stereotactic biopsy histopathological examination resulted in the diagnosis of a glioblastoma (WHO grade IV), IDH 1 wildtype (R132), IDH 2 wildtype (R172), HIST1H3B/C wildtype, TERT wildtype (C228 and C250), BRAF wildtype, and unmethylated MGMT promotor. The patient received definitive chemoradiation with TMZ to a total dose of 60Gy incl. proton boost of 5x2 GyRBE. TTFields therapy in combination with TMZ was initiated 4 weeks after completion of chemoradiation, TMZ maintenance was completed per protocol after 6 cycles. TTFields therapy was continued for more than 13 month and to-date the patient is still on therapy.
RESULTS
Current follow up time is 20 months after initial diagnosis with the patient showing a radiological complete response. In a MRI 9 months after proton therapy, partial response and perfusion restriction in the tumor area was observed. Another MRI 3 months later showed a complete response without perfusion signal in the tumor area.
CONCLUSION
Complete response was observed following combination treatment of chemoradiation with TMZ including proton boost, TMZ maintenance and TTFields in a patient with pathologically confirmed GBM IDH wildtype. To our knowledge, this is the first report on a ndGBM patient receiving proton therapy followed by TTFields therapy.
