Abstract
BACKGROUND Extended interval dosing (ED) for inhibitors of programmed cell death protein 1 (anti-PD-1) (nivolumab, pembrolizumab) or its ligand (anti-PD-L1) (durvalumab) were recently approved based on pharmacokinetic model results that predicted a benefit-risk profile comparable with the standard dosing (SD) regimen. However, safety data in real-world condition of use are lacking. The objective was to compare the incidence and the risk factors of serious immune-related adverse events (irAEs) and any-grade irAEs between the SD and ED regimens in patients treated with anti-PD-1 or anti-PD-L1. MATERIALS AND METHODS IrAEs were assessed from medical records in all new users of nivolumab, pembrolizumab, or durvalumab between 1 January 2019 and 31 December 2020 across two oncology centers in France. The incidence of irAEs was compared between both dosing regimens using Cox proportional hazards models adjusting for the main available confounders. RESULTS Among 686 patients included, 63% were new users of an SD regimen, 14% of ED regimen, and 23% started with SD and switched to ED regimen during follow-up. Overall, 34.6% of patients experienced at least one irAE of any grade and 11.4% presented at least one serious grade ≥3 irAE. No statistical difference was found between the SD and ED regimen on the risk of grade ≥3 irAEs [adjusted hazard ratio (HR) 1.40, 95% confidence interval (CI) 0.71-2.76] but our results suggest an increased risk of any-grade irAEs with the ED regimen (adjusted HR 1.46, 95% CI 1.00-2.12, P = 0.048). IrAEs resolved without sequelae in 46.4% of cases, and they were fatal for three patients (0.4%). Autoimmune pre-existing condition was confirmed as a risk factor for grade ≥3 irAEs (HR 2.56, 95% CI 1.53-4.27) and for all-grade irAEs (HR 1.60, 95% CI 1.17-2.20). CONCLUSIONS In a real-world setting, according to the regimen chosen by the oncologist based on clinical characteristics, we did not observe an increase in grade ≥3 irAE incidence between the SD and ED regimens.

Abstract
BACKGROUND Compelling evidence supports the role of childhood traumatization in the etiology of psychiatric disorders, including adult attention-deficit hyperactivity disorder (aADHD) and borderline personality disorder (BPD). The aim of this study was to examine the psychometric properties of the Hungarian version of the Childhood Trauma Questionnaire Short Form (H-CTQ-SF) and to investigate the differences between patients diagnosed with aADHD and BPD in terms of early traumatization. METHODS Altogether 765 (mean age = 32.8 years, 67.7% women) patients and control subjects were enrolled from different areas of Hungary. Principal component analysis and confirmatory factor analysis were carried out to explore the factor structure of H-CTQ-SF and test the validity of the five-factor structure. Discriminative validity was assessed by comparing clinical and non-clinical samples. Subsequently, aADHD and BPD subgroups were compared with healthy controls to test for the role of early trauma in aADHD without comorbid BPD. Convergent validity was explored by measuring correlations with subscales of the Personality Inventory for DSM-5 (PID-5). RESULTS The five scales of the H-CTQ-SF demonstrated adequate internal consistency and reliability values. The five-factor model fitted the Hungarian version well after exclusion of one item from the physical neglect scale because of its cross-loading onto the emotional neglect subscale. The H-CTQ-SF effectively differentiated between the clinical and non-clinical samples. The BPD, but not the aADHD group showed significant differences in each CTQ domain compared with the healthy control group. All CTQ domains, except for physical abuse, demonstrated medium to high correlations with PID-5 emotional lability, anxiousness, separation insecurity, withdrawal, intimacy avoidance, anhedonia, depressivity, suspiciousness, and hostility subscales. CONCLUSIONS Our study confirmed the psychometric properties of the H-CTQ-SF, an easy-to-administer, non-invasive, ethically sound questionnaire. In aADHD patients without comorbid BPD, low levels of traumatization in every CTQ domain were comparable to those of healthy control individuals. Thus, the increased level of traumatization found in previous studies of aADHD might be associated with the presence of comorbid BPD. Our findings also support the role of emotional neglect, emotional abuse and sexual abuse in the development of BPD.

Abstract
The presence of doubly excited states (DESs) above the core-hole ionization threshold nontrivially modulates the x-ray absorption because the participator Auger decay couples DESs to the underlying low-energy core-hole continuum. We show that coupling also affects the high-energy continuum populated by the spectator Auger decay of DESs. For the K-L_{23}^{2} Auger decay of the 1s^{-1}3p^{-1}4s^{2}^{1}P state in argon, the competing nonresonant path is assigned to the recapture of the 1s photoelectron caused by emission of the fast electron from the shake-up K-L_{23}^{2} decay of the 1s^{-1} ion.

Abstract
Dynamical response of water exposed to x-rays is of utmost importance in a wealth of science areas. We exposed isolated water isotopologues to short x-ray pulses from a free-electron laser and detected momenta of all produced ions in coincidence. By combining experimental results and theoretical modeling, we identify significant structural dynamics with characteristic isotope effects in H2O2+, D2O2+, and HDO2+, such as asymmetric bond elongation and bond-angle opening, leading to two-body or three-body fragmentation on a timescale of a few femtoseconds. A method to disentangle the sequences of events taking place upon the consecutive absorption of two x-ray photons is described. The obtained deep look into structural properties and dynamics of dissociating water isotopologues provides essential insights into the underlying mechanisms.

Abstract
We studied N 1s-1 inner-shell processes of the free base Phthalocyanine molecule, H2Pc, in the gas-phase. This complex organic molecule contains three different nitrogen sites defined by their covalent bonds. We identify the contribution of each site in ionized, core-shell excited or relaxed electronic states by the use of different theoretical methods. In particular, we present resonant Auger spectra along with a tentative new theoretical approach based on multiconfiguration self-consistent field calculations to simulate them. These calculations may pave the road towards resonant Auger spectroscopy in complex molecules.

Abstract
We present a study on molecular-frame photoelectron angular distributions (MFPADs) of small molecules using circularly polarized synchrotron light. We find that the main forward-scattering peaks of the MFPADs are slightly tilted with respect to the molecular axis. This tilt angle is directly connected to the molecular bond length by a simple, universal formula. We apply the derived formula to several examples of MFPADs of C 1s and O 1s photoelectrons of CO, which have been measured experimentally or obtained by means of ab initio modeling. In addition, we discuss the influence of the back-scattering contribution that is superimposed over the analyzed forward-scattering peak in the case of homo-nuclear diatomic molecules such as N2.

Abstract
BACKGROUND AND PURPOSE In patients with stroke, IV cone-beam CTA in the angiography suite could be an alternative to CTA to shorten the door-to-thrombectomy time. However, image quality in cone-beam CTA is typically limited by artifacts. This study evaluated a prototype dual-layer detector cone-beam CT angiography versus CTA in patients with stroke. MATERIALS AND METHODS A prospective, single-center trial enrolled consecutive patients with ischemic or hemorrhagic stroke on initial CT. Intracranial arterial segment vessel conspicuity and artifact presence were evaluated on dual-layer cone-beam CTA 70-keV virtual monoenergetic images and CTA. Eleven predetermined vessel segments were matched for every patient. Twelve patients were necessary to show noninferiority to CTA. Noninferiority was determined by the exact binomial test; the 1-sided lower performance boundary was prospectively set to 80% (98.75% CI). RESULTS Twenty-one patients had matched image sets (mean age, 72 years). After excluding examinations with movement or contrast media injection issues, all readers individually considered dual-layer cone-beam CT angiography noninferior to CTA (CI boundary, 93%, 84%, 80%, respectively) when evaluating arteries relevant in candidates for intracranial thrombectomy. Artifacts were more prevalent compared with CTA. The majority assessment rated each individual segment except M1 as having noninferior conspicuity compared with CTA. CONCLUSIONS In a single-center stroke setting, dual-layer detector cone-beam CTA virtual monoenergetic images are noninferior to CTA under certain conditions. Notably, the prototype is hampered by a long scan time and is not capable of contrast media bolus tracking. After excluding examinations with such scan issues, readers considered dual-layer detector cone-beam CTA noninferior to CTA, despite more artifacts.

Abstract
We herein report two cases of cathinone intoxication. The first case is about a drug addict who was admitted to the emergency room after the injection of an unknown compound. He presented with tachycardia, palpitations, mydriasis, dyspnea, dizziness, headache and nausea. After leaving the hospital against medical advice, he returned the next day with police escort, presenting aggressiveness and agitation signs. One month later, he returned one more time for sleeping disorders, hallucinations and anxiety. He was finally transferred for his 21st detoxification treatment. The second case concerns a man who was wandering the streets and tried to escape when police officers called him. He confessed to snorting of N-ethylpentedrone and was admitted with severe agitation including delusion of persecution, tachycardia, mydriasis and fever. Because of renal failure, rhabdomyolysis and metabolic acidosis, he was transferred to the intensive care unit where he manifested worsening of the symptoms, turning into coma. He was intubated for 3 days before a complete resolution of the symptoms. A screening was performed by high-resolution mass spectrometry followed by quantifications made by high-performance liquid chromatography coupled with a diode array detector. In the first case, alpha-pyrrolidinohexiophenone was identified only during the first two admissions. However, as plenty of other psychotropic substances were also found, the cathinone alone could not be held directly responsible for the symptoms. In the second case, more than 2,000 ng/mL of N-ethylpentedrone was found without any decrease in the next 17 h, underlining the long half-life of this compound. Unlike the first case, symptoms could be clearly attributed to the cathinone. In conclusion, cathinones can be found on the Belgian illicit drug market, with various routes of administration and clinical consequences. In these two case reports, some common points were observed initially. However, one patient was finally able to leave the hospital without any treatment, whereas the other would most likely have died without intensive care.

Abstract
Background
Cavitating ultrasonic aspirator (CUSA) devices are commonly used in neurosurgical procedures to carefully debulk tumor from adjacent healthy brain tissue. Here, we explore the feasibility of using ultrasonic minced tumor tissue to classify otherwise discarded sample material by DNA methylation according to the respective World Health Organization (WHO) Classification of Tumors of the Central Nervous System (CNS) using low pass nanopore whole genome sequencing.
Material and Methods
21 ultrasonic aspirated specimens from patients undergoing surgery in the department of pediatric neurosurgery at the Charité-Universitätsmedizin Berlin with either newly diagnosed cerebral lesions or pre-treated lesions were processed by nanopore sequencing to generate copy number profiles and ad-hoc random forest classification. Results were compared to microarray-based routine profiling. Tumor purity was assessed.
Results
In 19/21 (90.5 %) samples the minimum amount of 1,000 CpG sites were sequenced. In 20/21 (95.2 %) cases copy number variation profiles could be generated and matched microarray derived copy number profiles, allowing for identification of diagnostically or therapeutically relevant pathognomonic alterations. 12/17 (70.6 %) samples were concordantly classified to the corresponding microarray-based diagnosis by routine neuropathological workup. Applying recently defined thresholds for nanopore-based classification resulted in sensitivity of 64.7 % and specificity of 100 %.
Conclusion
CUSA referred sample material of pediatric brain tumors allows for methylation-based classification according to the respective WHO classification of CNS tumors with acceptable sensitivity and high specificity. Hereby, a promising opportunity for accurate classification of pediatric brain tumors by a time- and cost-efficient advanced molecular technique is offered using otherwise discarded tumor tissue.

Abstract
Using a magnetic bottle multi-electron time-of-flight spectrometer in combination with synchrotron radiation, double-core-hole pre-edge and continuum states involving the K-shell of the carbon atoms in n-butane ( n-C4H10) have been identified, where the ejected core electron(s) and the emitted Auger electrons from the decay of such states have been detected in coincidence. An assignment of the main observed spectral features is based on the results of multi-configurational self-consistent field (MCSCF) calculations for the excitation energies and static exchange (STEX) calculations for energies and intensities. MCSCF results have been analyzed in terms of static and dynamic electron relaxation as well as electron correlation contributions to double-core-hole state ionization potentials. The analysis of applicability of the STEX method, which implements the one-particle picture toward the complete basis set limit, is motivated by the fact that it scales well toward large species. We find that combining the MCSCF and STEX techniques is a viable approach to analyze double-core-hole spectra.

Abstract
PURPOSE Proton pump inhibitors (PPIs) inhibit fatty acid synthase (FAS), a critical enzyme in lipogenesis, energy balance, and cancer cell survival. We aimed to evaluate the association of PPI use with incidence of common obesity- related cancers in women: postmenopausal breast, colorectal, and endometrial cancers. METHODS Our study included 124,931 postmenopausal who were enrolled in the Women's Health Initiative (WHI) observational study and clinical trials, and had responded to a year 3 follow-up assessment. We examined prescription and over the counter use of PPI and/or histamine 2 receptor antagonists (H2RA) at baseline and year 3, to isolate potential effects of FAS inhibition by PPI rather than simply acid suppression. Incident cancer cases were physician-adjudicated. Cox proportional hazard regression models were used to estimate multivariable hazard ratios (HR) and 95% confidence intervals (CI) for associations between PPI and/or H2RA use and cancer incidence after year 3. RESULTS There were 7956 PPI ever users (with or without H2RA use) and 9398 H2RA only users. PPI or H2RA use was not associated with risk of breast cancer (n=9186 cases), compared to women who did not use either agent (HR 1.01, 95% CI 0.93-1.10 and HR 0.95 95% CI 0.87-1.03, respectively). The incidence of colorectal cancer (n=2280) was significantly lower in PPI users (HR 0.75, 95% CI 0.61-0.92), but not in H2RA users (HR 1.13, 95% CI 0.97-1.31). This association was strengthened with increasing duration (p=0.006) and potency (p=0.005) of PPI use and held regardless of BMI or NSAID use. PPI or H2RA use was not associated with endometrial cancer (n=1231) (HR 0.81, 95% CI 0.61-1.07 and HR 1.13, 95% CI 0.91-1.40, respectively), but showed a trend in decreased risk with increasing PPI potency (P=0.048). CONCLUSIONS Among postmenopausal women, PPI use, but not H2RA use, demonstrated an inverse, dose-responsive association with colorectal cancer incidence. This was consistent with preclinical data that FAS inhibition prevents colon cancer progression and supports further investigation of this commonly used medication as a cancer preventive agent. PPI use was not associated with incidence of breast or endometrial cancer.

Abstract
Introduction
Childhood maltreatment (CM) contributes to negative mental and physical health outcomes including major depressive disorder (MDD), and an elevated risk for cardiovascular disease (CDV) in adults. Also, childhood maltreatment can be related to mentalizing deficits in MDD. Cardio-metabolic diseases often coincide with MDD and worsen its course and outcome. Little is known on the interplay of these factors.
Objectives
We examined MDD patients with and without CM to explore the effects of CM on serum lipid and lipoprotein levels and assessed their mentalizing abilities. Self-oriented mentalizing was operationalized as emotional self-awareness/alexithymia, other-oriented mentalizing was defined as theory of mind (ToM).
Methods
MDD patients (N=42) and healthy controls (n=20) matched in age, sex, and lifestyle were investigated. Total cholesterol, triglycerides, high- and low-density lipoproteins (HDL-C and LDL-C), body mass index, and exercise in a typical week were measured. Beck Depression Inventory, Childhood Trauma Questionnaire, Toronto Alexithymia scale, and the Reading the mind in the Eyes Test were used to assess clinical symptoms, mentalizing abilities and CM.
Results
After controlling for depressive symptom severity, demographic and lifestyle variables, CM was found to be a strong predictor of serum lipid alterations. Mentalizing deficits correlated with CM. Serum triglycerides, HDL-C were significant predictors of ToM performance (P<0.05, and P=0.005) and alexithymia (P< 0.05, and P< 0.05) in the MDD group.
Conclusions
Several, inter-correlated pathways may mediate the undesirable effects of CM on the course and outcome of MDD. According to our preliminary results, diminished self-awareness and ToM can be possible mediating factors.

Abstract
Introduction
Early life stress (ELS) is a significant risk factor for major depressive disorder (MDD) in adults. Functional magnetic resonance imaging (fMRI) studies using face emotion processing paradigms have found altered blood-oxygen-level-dependent (BOLD) responses in the cortico-limbic network both in individuals exposed to ELS and in patients with MDD. Thus, early life stress may have a long-lasting impact on brain areas responsible for the processing of socio-affective
cues.
Objectives
By applying a facial emotion recognition (FER) fMRI paradigm, we examined the long-term effect of childhood adversity on brain activity in MDD patients with and without ELS.
Methods
MDD patients without ELS (MDD, N=19), those with ELS (MDD+ELS, N=21), and healthy controls (HC, N=21) matched for age, sex, and intelligence quotient underwent fMRI scanning while performing a block design FER task with faces expressing negative emotions. The severity of ELS was assessed with the 28-item Childhood Trauma Questionnaire.
Results
Both MDD and MDD+ELS patients were slightly impaired in recognizing sad faces. Statistical analysis of brain activity found that MDD+ELS patients had significantly reduced negative BOLD responses in the right anterior paracingulate gyrus, subcallosal cortex accumbens compared to HCs. Moreover, the MDD+ELS group had a significantly increased negative BOLD signal in the right postcentral and precentral gyri relative to the HC group. MDD+ELS patients had reduced negative BOLD response in their anterior paracingulate gyrus compared to the MDD group.
Conclusions
Our results support that adult MDD patients with significant ELS are impaired in facial emotion recognition and they display functional alterations in the frontostriatal circuits.

Abstract
BackgroundVariable disease presentation and symptom burden in patients living with systemic sclerosis (SSc) require a chronic care approach including competent, coordinated, multidisciplinary collaboration as well as self-management support targeting individual patient needs. The Chronic Care Model (CCM) is a longstanding and widely adopted model guiding chronic illness management.1 Little is known about how CCM elements are implemented in SSc care or how patients’ care experiences relate to health-related quality of life (HRQoL).ObjectivesFirst, to describe current SSc care in Switzerland according to the CCM from the patient perspective and examine relationships with HRQoL. Second, to explain these results by patients’ illness and care experiences.MethodsWe employed an explanatory sequential mixed methods design (Figure 1). First, we conducted a cross-sectional quantitative survey (n=101 Swiss patients) using the Patient Assessment of Chronic Illness Care (PACIC-20)2 and Systemic Sclerosis Quality of Life (SScQoL)3 questionnaires. Because PACIC has not been used in the context of SSc, we used the Mokken model to test the construct validity of the PACIC scale and its subscales. After excluding five problematic items, H coefficients were ‘strong’ for the subscales and the global scale (0.52) suggesting a robust unidimensional scale.Figure 1.Schematic of the explanatory, sequential mixed methods designNext, we used data from individual patient interviews (n=4) and one patient focus group (n=4) to further explore care experiences of people living with SSc with a focus on the PACIC dimensions.ResultsThe mean overall PACIC-15 score was 3.0 / 5.0 (95% CI: 2.8–3.2, n= 100), indicating care was ‘never’ to ‘generally not’ aligned with the CCM. Lowest subscale scores related to ‘goal setting/tailoring’ (mean = 2.5, 95% CI: 2.2–2.7) and ‘problem solving/contextual counselling’ (mean = 2.9, 95% CI: 2.7–3.2) (Table 1). No significant associations were identified between the mean PACIC-15 and SScQoL scores.Table 1.Summary of scores (n=101) for the 15-item PACIC scale (adapted version of the original 20-item scale)PACIC mean scores (95% CI)PACIC 15-item mean score3.0 (2.8–3.2)1: Patient activation(mean of items 1–3)3.4 (3.1–3.6)2: Delivery system design/ Decision Support(items 4–6)3.2 (3.0–3.4)3: Goal setting/ Tailoring(items 7–9)2.5 (2.2–2.7)4: Problem solving/ Contextual Counselling(items 12–15)2.9 (2.7–3.2)5: Follow-up/ Coordination(items 19–20)3.3 (3.0–3.5)Note: CI=Confidence interval; PACIC=Patient Assessment of Chronic Illness CareInterviews revealed patients frequently encounter major shortcomings in care including experiencing organized care with limited participation, not knowing which strategies are effective or harmful and feeling left alone with disease and psychosocial consequences. Patients often responded to challenges by dealing with the illness in tailored measure, taking over complex coordination of care and relying on an accessible and trustworthy team.ConclusionThe low PACIC mean overall score is comparable to findings in patients with common chronic diseases. Key elements of the CCM have yet to be systematically implemented in Swiss SSc management. Identified gaps in care related to lack of shared decision-making, goal-setting and individual counselling –aspects that are essential for supporting patient self-management skills. Furthermore, there appears to be a lack of complex care coordination tailored to individual patient needs.References[1]Wagner EH.

Abstract
Auger decay after photoexcitation or photoemission of an electron from a deep inner shell in the hard X-ray regime can be rather complex, implying a multitude of phenomena such as multiple-step cascades, post-collision interaction (PCI), and electronic state-lifetime interference. Furthermore, in a molecule nuclear motion can also be triggered. Here we discuss a comprehensive theoretical method which allows us to analyze in great detail Auger spectra measured around an inner-shell ionization threshold. HCl photoexcited or photoionized around the deep Cl 1s threshold is chosen as a showcase. Our method allows calculating Auger cross sections considering the nature of the ground, intermediate and final states (bound or dissociative), and the evolution of the relaxation process, including both electron and nuclear dynamics. In particular, we show that we can understand and reproduce a so-called experimental 2D-map, consisting of a series of resonant Auger spectra measured at different photon energies, therefore obtaining a detailed picture of all above-mentioned dynamical phenomena at once.

Abstract
The regulatory landscape of flavorings is evolving, thereby putting pressure on control laboratories to develop analytical methods for a wide range of compounds in various types of food and drinks. In order to improve the monitoring of flavoring substances, a versatile and accurate analytical method using the solvent-assisted flavor evaporation (SAFE) technique coupled to GC-MS(SIM) was developed and validated. Focus was put on authorized flavoring substances requiring specific attention due to a genotoxic concern based on information from European risks assessment reports. Thirty-seven (suspected) genotoxic flavoring substances were analyzed in a selection of ten alcohol-free beers. Five suspected genotoxic compounds (i.e. 1-(2-furyl)-2-propanone, 2-acetylfuran, 2-acetyl-5-methylfuran, 2-acetyl-3,5-dimethylfuran, hex-2-eno-1,4-lactone) as well as two confirmed genotoxic flavoring substances (p-mentha-1,8-dien-7-al, 2,4-pentanedione) were identified and quantified among the selected samples. Low concentrations and natural occurrences of the identified compounds suggested that these were not added as such but rather originated from heat-treatments or from plant-based extracts.

Abstract
BACKGROUND Alzheimer's disease (AD) and frontotemporal lobar degeneration (FTLD) are heterogeneous in their clinical presentation and underlying pathology, but they often have overlapping features. Diagnostic accuracy is critical for guiding patient management. Cerebrospinal fluid (CSF) diagnostic assays for the differentiation of AD and FTLD may increase diagnostic accuracy. OBJECTIVES In this study, we aimed to understand the potential role of CSF biomarkers and biomarker ratios, measured using Elecsys® CSF immunoassays (Roche Diagnostics International Ltd, Rotkreuz, Switzerland), in the differential diagnosis of AD and FTLD. DESIGN This study was conducted at a single center in Munich, Germany between July 2019 and July 2020. Patient CSF samples were retrospectively collected from the study center biobank. PARTICIPANTS A total of 130 patients with cognitive impairment were included in the study; 86 patients were diagnosed with AD and 44 with FTLD (behavioral variant frontotemporal dementia, semantic variant of primary progressive aphasia, and non-fluent variant of primary progressive aphasia), based on core clinical criteria and a non-CSF biomarker, a typical pattern of regional hypometabolism on [18F] fluorodeoxyglucose positron emission tomography. MEASUREMENTS Patient CSF biomarker concentrations were measured using Elecsys CSF immunoassays. Receiver operating characteristic analyses were conducted to determine areas under the curve (AUCs) for CSF biomarker performance. Sensitivity and specificity analyses were conducted to evaluate the performance of established cut-offs (Aβ42 ≤1000 pg/mL, pTau181/Aβ42 ratio >0.024, and tTau/Aβ42 ratio >0.28) and optimized cut-offs based on Youden's index. RESULTS AUC-based performance was similarly good for the pTau181/Aβ42 ratio (AUC=0.841; 95% CI: 0.759-0.923), pTau181/Aβ40 ratio (AUC=0.837; 95% CI: 0.754-0.919), Aβ42/Aβ40 ratio (AUC=0.829; 95% CI: 0.746-0.912), tTau/Aβ42 ratio (AUC=0.822; 95% CI: 0.736-0.908), pTau181/Aβ42/Aβ40 ratio (AUC=0.817; 95% CI: 0.734-0.901), and Aβ42 (AUC=0.812; 95% CI: 0.722-0.902). Performance was slightly lower for the tTau/Aβ42/Aβ40 ratio (AUC=0.799; 95% CI: 0.713-0.885), pTau181 alone (AUC=0.793; 95% CI: 0.707-0.880), tTau/Aβ40 ratio (AUC=0.751; 95% CI: 0.657-0.844), and tTau alone (AUC=0.706; 95% CI: 0.613-0.799). The highest qualitative performance was observed with the pTau181/Aβ42 ratio with an established cut-off value of >0.024 and optimized cut-off value of >0.022: sensitivity and specificity values were 0.892 and 0.773, respectively. CONCLUSIONS Elecsys CSF immunoassays demonstrate good diagnostic accuracy in differentiating patients with AD from those with FTLD. These immunoassays have the potential to support clinical decision making, i.e. in diagnosing patients with FTLD by excluding patients with amyloid positivity, which is indicative of underlying AD.

Abstract
Vertebral osteomyelitis (VO) is an infection of the spine mainly caused by bacterial pathogens. The pathogenesis leading to destruction of intervertebral discs (IVDs) and adjacent vertebral bodies (VBs) is poorly described. The present study aimed at investigating the connection between infection and bone/disc metabolism in VO patients. 14 patients with VO (infection group) and 14 patients with burst fractures of the spine (fracture group; control) were included prospectively. Tissue biopsies from affected IVDs and adjacent VBs were analysed by RT-qPCR for mRNA-expression levels of 18 target genes including chemokines, adipokines and genes involved in bone metabolism. Most importantly, the receptor activator of NF-κB/osteoprotegerin (RANK/OPG) expression ratio was drastically elevated in both VBs and IVDs of the infection group. In parallel, expression of genes of the prostaglandin-E2-dependent prostanoid system was induced. Such genes regulate tissue degradation processes via the triad OPG/RANK/RANKL as well as via the chemokines IL-8 and CCL-20, whose expression was also found to be increased upon infection. The gene expression of the adipokine leptin, which promotes inflammatory tissue degradation, was higher in IVD tissue of the infection group, whereas the transcription of omentin and resistin genes, whose functions are largely unknown in the context of infectious diseases, was lower in infected VBs. In summary, similar expression patterns of pro-inflammatory cytokines and pro-osteoclastogenic factors were identified in VBs and IVDs of patients suffering from VO. This suggests that common immuno-metabolic pathways are involved in the mechanisms leading to tissue degradation in VBs and IVDs during VO.

Abstract
Major depressive disorder is a leading cause of disability worldwide. Because conventional therapies are ineffective in many patients, novel strategies are needed to overcome treatment‐resistant depression (TRD). Limiting factors of successful drug development in the last decades were the lack of (1) knowledge of pathophysiology, (2) translational animal models and (3) objective diagnostic biomarkers. Here, we review novel drug targets and drug candidates currently investigated in Phase I–III clinical trials. The most promising approaches are inhibition of glutamatergic neurotransmission by NMDA and mGlu5 receptor antagonists, modulation of the opioidergic system by κ receptor antagonists, and hallucinogenic tryptamine derivates. The only registered drug for TRD is the NMDA receptor antagonist, S‐ketamine, but add‐on therapies with second‐generation antipsychotics, certain nutritive, anti‐inflammatory and neuroprotective agents seem to be effective. Currently, there is an intense research focus on large‐scale, high‐throughput omics and neuroimaging studies. These results might provide new insights into molecular mechanisms and potential novel therapeutic strategies.

Abstract
The interaction of intense femtosecond x-ray pulses with molecules sensitively depends on the interplay between multiple photoabsorptions, Auger decay, charge rearrangement, and nuclear motion. Here, we report on a combined experimental and theoretical study of the ionization and fragmentation of iodomethane (CH_{3}I) by ultraintense (∼10^{19} W/cm^{2}) x-ray pulses at 8.3 keV, demonstrating how these dynamics depend on the x-ray pulse energy and duration. We show that the timing of multiple ionization steps leading to a particular reaction product and, thus, the product's final kinetic energy, is determined by the pulse duration rather than the pulse energy or intensity. While the overall degree of ionization is mainly defined by the pulse energy, our measurement reveals that the yield of the fragments with the highest charge states is enhanced for short pulse durations, in contrast to earlier observations for atoms and small molecules in the soft x-ray domain. We attribute this effect to a decreased charge transfer efficiency at larger internuclear separations, which are reached during longer pulses.

Abstract
Background:Rheumatoid arthritis (RA) is independently associated with an increased risk of cardiovascular disease (CVD). One of the early stages of atherosclerosis is endothelial dysfunction, which is increased in RA. Using drugs to target endothelial dysfunction is a promising novel strategy for CVD prevention in RA. Sildenafil has been shown to improve endothelial function in diabetics, who have similar increased CVD risk. Our hypothesis was that sildenafil use may be a novel primary CVD prevention strategy in RA.Objectives:To determine if sildenafil use in RA patients improves endothelial dysfunction (as measured by brachial artery flow-mediated dilation [FMD] and peripheral arterial tone [PAT]), as well as serum inflammatory and atherosclerosis biomarkers.Methods:This NIH-funded study was a phase II, randomized double-blind placebo-controlled crossover efficacy trial of 25 RA patients, with no known history of CVD, but at least one traditional CVD risk factor. Patients were randomized 1:1 to receive either sildenafil or placebo for 3 months, then after a 2-week washout, crossed over to each respective group for an additional 3 months. Vascular studies (FMD and PAT) and serum atherosclerosis biomarkers (e-Selectin, ICAM-1, VCAM-1) were performed at baseline, 3 months pre- and post-washout, and 6 months. Adverse events were collected. Given the cross-over design, analyses included a random effects model for within-subject comparisons of sildenafil versus placebo periods, adjusting for the baseline (FMD or EndoPAT) within that period and a term for treatment order. All tests were 2-sided with α=0.05.Results:A total of 233 subjects were assessed for eligibility, with 25 subjects being randomized after written informed consent. A total of 13 subjects were randomized to placebo first, and 12 to sildenafil first. Baseline characteristics were similar between those randomized to Placebo vs. Sildenafil first. Mean age was 62.0+/-10.9 years; 84% were female; and 92% were white. A total of 6 adverse events experienced in 3 subjects occurred. The primary endpoint (increase in %FMD in Sildenafil period vs. Placebo period) was not significant (p=0.19). However, note the study was powered at 80% to detect an effect size of 0.37 for change in %FMD or biomarker with a sample size of 60, not 25. However, sildenafil use was associated with a significant increase (improvement) by 0.200 units of PAT ratio (p=0.003) compared with placebo, adjusted by treatment order and baseline PAT ratio (within the given treatment period). Exploratory linear mixed models comparing e-Selectin, ICAM-1, and VCAM-1 between Sildenafil vs. Placebo periods, adjusted for treatment order and the baseline biomarker level, did not show any significant differences except for ICAM-1 (55.3 units higher in Sildenafil vs. Placebo periods, p=0.011).Conclusion:In this pilot trial of 25 RA subjects, sildenafil use was associated with a significant increase (improvement) in endothelial function as measured by PAT. However, there was no significant difference in FMD. The study is limited due to the small sample size, which was impacted by slow recruitment as well as the COVID-19 pandemic. Future larger studies are required to assess whether other PDE5 inhibitors may improve endothelial dysfunction in RA and other autoimmune disease patients at high risk of CVD.References:[1]Maradit-Kremers H, Crowson CS, Nicola PJ, et al.

Abstract
Using synchrotron radiation in the tender X-ray regime, a photoelectron spectrum showing the formation of single site double-core-hole pre-edge states, involving the K shell of the O atom in CO, has been recorded by means of high-resolution electron spectroscopy. The experimentally observed structures have been simulated, interpreted and assigned, employing state-of-the-art ab initio quantum chemical calculations, on the basis of a theoretical model, accounting for their so-called direct or conjugate character. Features appearing above the double ionization threshold have been reproduced by taking into account the strong mixing between multi-excited and continuum states. The shift of the σ* resonance below the double ionization threshold, in combination with the non-negligible contributions of multi-excited configurations in the final states reached, gives rise to a series of avoided crossings between the different potential energy curves.

Abstract
BACKGROUND Better patient knowledge on inflammatory bowel disease [IBD] could improve outcome and quality of life. The aim of this study was to assess if an education programme improves IBD patients' skills as regards their disease. METHODS The GETAID group conducted a prospective multicentre randomised controlled study. IBD patients were included at diagnosis, or after a significant event in the disease course. Patients were randomised between 'educated' or control groups for 6 months. Education was performed by trained health care professionals. A psycho-pedagogic score [ECIPE] was evaluated by a 'blinded' physician at baseline and after 6 and 12 months [M6 and M12]. The primary endpoint was the increase of ECIPE score at M6 of more than 20%. RESULTS A total of 263 patients were included in 19 centres (male:40%; median age:30.8; Crohn's disease [CD]:73%). Of these, 133 patients were randomised into the educated group and 130 into the control group. The median relative increase in ECIPE score at M6 was higher in the educated group as compared with the control group (16.7% [0-42.1%] vs 7% [0-18.8%], respectively, p = 0.0008). The primary endpoint was met in 46% vs 24% of the patients in the educated and control groups, respectively [p = 0.0003]. A total of 92 patients met the primary endpoint. In multivariate analysis, predictors of an increase of at least 20% of the ECIPE score were randomisation in the educated group (odds ratio [OR] = 2.59) and no previous surgery [OR = 1.92]. CONCLUSIONS These findings support the set-up of education programmes in centres involved in the management of IBD patients.

Abstract
This essay presents two studies of Bertalan Petho's rich and diverse oeuvre. The first one (published in 1967) analyzed a schizophrenic composer-patient's composition created during the acute phase of schizophrenia and consi - dered the hiatus discursivitatis as one of the main characteristics of the pathology of expression in his musical works. The second study is the patients' catamnestic follow-up after 13 years. In that late, chronic, residual phase of schizophrenia with overwhelmingly negative symptoms, the mannieristic catatonia dominated the clinical feature, as well as the pathology of musical expression. These two studies build a bridge between music and psychopathology in a way unique in the literature and greatly demonstrate the utilization of musical expression in the phenomenological approach of schizophrenia. Due to Berta - lan Petho's high level of musical literacy, his knowledge of music theory and harmony, we have an insight through a specific window into the severe self-disturbance and alienisation determining the schizophrenic world of experience. Petho's approach is still relevant today: it fits conceptually to the most novel phenome-nological framework of the psychopathology of schizophrenia, i.e. to the ipseity-hyperreflexivity model, as well as to theories that draw a parallel between the schizophrenic reification and alienisation and the 20th-century modernism.

Abstract
BACKGROUND Detection of childhood traumas is important both in clinical practice and in research. There is a pressing need for methods that are relatively simple but comprehensive, non-intrusive, and possess adequate psyc - ho metric properties. In this study we translated one of the most widely used and well-studied measure of childhood abuse and neglect and explored the psychometrical properties of this questionnaire. METHODS The study was based on data from a clinical (N=171) and a normative (N=358) sample. In total 529 adults participated in the testing process. Beside the trauma questionnaire Parental Bonding Inventory, Impact of Events Scale and Dissociative Experiences Scale were administered. RESULTS We examined the internal consistency of the translated trauma questionnaire. The Cronbach's a coefficients for the five subscales ranged from 0,639 to 0,934. Participants in the clinical sample reached higher scores on all trauma subscales except sexual abuse, than normative adults [PA: t (398)=-2,771; p=0,006; PN: t (398)=-5,990; p=0,000; EA: t (398)=-3,679; p=0,000; EN: t (398)=-4,759; p=0,000; total score: t (398)=-4,669; p=0,000]. Correlations among the trauma questionnaire total score and the scales of Parental Bonding Inventory indicating some medium effects (with maternal care: r=-0,661; p=0,000; with paternal care: r=-0,483; p=0,000). CONCLUSION Our preliminary findings suggest that this trauma questionnaire is practical and facilitates the systema - tic evaluation of adverse early life events and maximizes the possibility of detecting childhood abuse and neglect.

Abstract
INTRODUCTION The introduction of tyrosine kinase inhibitors (TKIs) has revolutionized the therapy of chronic myeloid leukemia (CML). Although the efficacy of TKIs is beyond dispute, conception-related safety issues are still waiting to be explored, particularly in males. This systematic review aimed to summarize all available evidence on pregnancy outcomes of female spouses of male CML patients who fathered children after TKI treatment for CML. METHODS We performed a systematic search in seven electronic databases for studies that reported on male CML patients who did or did not discontinue TKI treatment before conceiving, and the pregnancy outcomes of their female spouse are available. The search centered on the TKI era (from 2001 onward) without any other language or study design restrictions. RESULTS Out of a total of 38 potentially eligible papers, 27 non-overlapping study cohorts were analyzed. All were descriptive studies (case or case series studies). Altogether, 428 pregnancies from 374 fathers conceived without treatment discontinuation, 400 of which (93.5%) ended up in a live birth. A total of ten offspring with a malformation (2.5%) were reported: six with imatinib (of 313 live births, 1.9%), two with nilotinib (of 26 live births, 7.7%), one with dasatinib (of 43 live births, 2.3%), and none with bosutinib (of 12 live births). Data on CML status were scarcely reported. Only nine pregnancies (from nine males) and no malformation were reported in males who discontinued TKI treatment before conception. CONCLUSION Malformations affected, on average 2.5% of live births from fathers who did not discontinue TKI treatment before conception, which is comparable with the rate of malformations in the general population. Large-scale studies with representative samples are awaited to confirm our results.

Abstract
Abstract
Background
Accurate volume status assessment is crucial for the treatment of acute decompensated heart failure (ADHF). Volume status assessment by physical exam is inaccurate, necessitating invasive measurement with right heart catheterization (RHC), which carries safety, pragmatic (scheduling, holding anticoagulants, etc) and financial burdens. Therefore, a reliable, non-invasive, cost-effective alternative is desired. Previously, we developed an ultrasound (US) based technique to measure internal jugular vein (IJV) compliance during RHC which was used for single time point central venous pressure (CVP) predictions. We now aim to apply this technique to track acute changes in CVP during diuresis for ADHF in patients with an in-dwelling pulmonary artery catheter.
Purpose
The objective of our study was to devise a rapid, portable and reliable alternative to RHC to track acute volume changes during treatment of ADHF.
Methods
We used an observational, prospective study design and recruited 15 patients from the CCU between 7/19–12/19 being treated for ADHF (systolic or diastolic) with IV diuretics +/−inotropic agents who underwent PA catheter insertion for continuous CVP monitoring. 13 of 15 patients received milrinone infusions. US images of the IJV were obtained at end expiration and during the strain phase of Valsalva at multiple 2–3 hr intervals. Change in IJV cross sectional area (ImageJ) was used as a measure of IJV compliance. Patients unable to perform the Valsalva maneuver and on mechanical circulatory support were excluded.
Results
Calculated % change in CSA of IJV was plotted against CVP. An inverse relationship was observed between CVP and % change in CSA of IJV. The data was fit with an inverse exponential regression shown in Figure 1 (R2=0.36, root mean square error = 3.19). Fivefold cross validation showed a stable model for predicting CVP based CSA (R2=0.34, root mean square error = 3.26)
Conclusion
Serial portable US assessment of IJV compliance can act a surrogate measure of CVP and,therefore, can provide reliable information on acute hemodynamic changes in ADHF.

Abstract
INTRODUCTION Puffy hand syndrome is a rare complication of intravenous drug addiction. Diagnosis is based on the patient's history and clinical examination. OBSERVATIONS A woman and two men, aged 42, 39 and 36 years old, are described. All had a history of intravenous drug use of heroin and oral buprenorphine misuse. Puffy hand syndrome appeared during drug addiction (n = 2) or after its withdrawal (n = 1). It was associated with acrocyanosis (n = 1) or injection scars (n = 1). Upper limb ultrasonography showed sequelae of venous (n = 3) or arterial (n = 1) thrombosis. An upper limb lymphoscintigraphy in one patient showed decreased radionuclide uptake of axillary lymph node and subdermal reflux tracer in the forearm. Treatment was based on low-stretch bandages to reduce the volume and then elastic compression sleeve for long-term stabilization. CONCLUSION Puffy hand syndrome seen in intravenous drug addicts is poorly understood. It is a chronic complication despite the cessation of drug use. This syndrome has to become more widely known because its management is mandatory, although symptomatic.

Abstract
Resonant inelastic x-ray scattering (RIXS) provides remarkable opportunities to interrogate ultrafast dynamics in liquids. Here we use RIXS to study the fundamentally and practically important hydroxyl radical in liquid water, OH(aq). Impulsive ionization of pure liquid water produced a short-lived population of OH(aq), which was probed using femtosecond x-rays from an x-ray free-electron laser. We find that RIXS reveals localized electronic transitions that are masked in the ultraviolet absorption spectrum by strong charge-transfer transitions-thus providing a means to investigate the evolving electronic structure and reactivity of the hydroxyl radical in aqueous and heterogeneous environments. First-principles calculations provide interpretation of the main spectral features.

Abstract
Background:People living with systemic sclerosis (SSc) often lack access to coordinated, specialized care and self-management support from qualified healthcare professionals. Such gaps lead to significant unmet health needs and inability to get preventive services. The Chronic Care Model (CCM) has been used to guide disease management across a wide range of chronic conditions. The CCM often uses e-health technologies to address self-management problems, connect patients with clinicians and reduce patient travel requirements.Objectives:To evaluate current SSc care practice patterns and elicit patient health technology readiness to define relevant aspects and resources needed to improve SSc chronic disease management.Methods:We employed a cross-sectional survey using the 20-item Patient Assessment of Chronic Illness Care (PACIC) instrument to assess how aspects of SSc care align with key components of the CCM.1Six items drawn from the ‘5A’ (ask, advise, agree, assist, and arrange) model of behavioural counselling were included (all 26 items scored on 5-point scale, 1=never to 5=always). Acceptance of health technology was evaluated by adapting and combining questionnaires from Vanhoof2and Halwas3. German and French speaking SSc patients (>18 years) were recruited from university/cantonal hospitals and the Swiss scleroderma patients’ association. Participants completed anonymous paper/online questionnaires. Data were analysed descriptively.Results:Of 101 SSc patients, most were female (76%), spoke German (78%) and had a median age of 60 years (IQR: 50-68). Median disease duration was 8 years (IQR: 5-15), spanning a range of severity (31% limited SSc, 36% diffuse SSc, 3% overlap syndrome). One-quarter (25%) did not know their disease subset.The mean overall PACIC score was relatively low (2.91±0.95) indicating that care was ‘never’ to ‘generally not’ aligned with the CCM. Lowest mean subscale scores related to Follow-up/ Coordination (2.64±1.02), Goal setting (2.68±1.07) and Problem-solving/Contextual Counselling (2.94±1.22). The single items ‘Given a copy of my treatment plan’ (1.99±1.38) and ‘Encouraged to attend programs in the community’ (1.89±1.16) were given the lowest ratings. The ‘5A’ summary score was 2.84±0.97.In terms of technology readiness, 43% completed the survey online. Most participants owned a smartphone (81%), laptop (63%) and/or desktop computer (46%). The overwhelming majority of patients (91%) reported using the Internet in the last year – primarily for communication (e.g. emails, text messages). Participants indicated relatively little experience with e-health applications and participating in SSc online forums or self-help groups.Conclusion:To improve chronic disease management of SSc patients in Switzerland, current care practices warrant reengineering taking CCM components into account. Specific unmet needs relate to self-management support, help patients set individualized goals, and coordinate continuous care. Web-based technologies incorporating user-centred design principles may be a reasonable option for improving care.References:[1]Glasgow, RE, et al.

Abstract
Background:The Systemic Sclerosis Quality of Life Questionnaire (SScQoL) has been validated in six European languages.1Previous adaptation into German revealed issues with the dichotomous response structure in 10 items necessitating a review of the tool and further psychometric testing with patients in German speaking countries.Objectives:The aim of this study was to assess the German version of the SScQoL, extend the response structure and test its construct validity using Mokken scale analysis.Methods:This was a mixed methods study involving cognitive debriefing and survey methods. The expert committee extended the response structure of the 10 items from dichotomous to polytomous (4-point) responses: ‘always’, ‘usually’, ‘sometimes’ and ‘never’. In cognitive debriefing, a small convenience sample of patients with SSc completed the new version while ‘thinking aloud’ and commented on relevance of the items and the response structure.Results:In cognitive debriefing, six patients with SSc completed the new German SScQoL and reported problems with the remaining dichotomous items. These were subsequently converted into polytomous 4-point response structure by the expert committee.Conclusion:The German SScQoL has been revised into polytomous item structure and shown to be a valid and reliable measure of health-related quality of life in SSc. Further cross-cultural validity tests are required to assess its measurement equivalence with other SScQoL versions and thus enable multinational comparisons.References:[1]Ndosi M, Alcacer-Pitarch B, Allanore Y et al.
