„Wut im Ohr“: Misophonie
Authors: Schwemmle C. , Arens C. 
Published: June 2021

ZusammenfassungDie Misophonie ist eine Intoleranz auf bestimmte Alltagsgeräusche. Hierbei fungieren als „Trigger“ „menschliche Körpergeräusche“, z. B. Schlucken/Schmatzen/Atemgeräusche oder Geräusche, die von Menschen, aber nicht vom menschlichen Körper erzeugt werden (z. B. Klicken Kugelschreiberknopf), ferner Tier‑/Maschinengeräusche. Die Betroffenen verspüren sofort eine negativ-emotionale Reaktion wie Wut, Aggression, Ekel u.a. Objektivierbare Veränderungen sind Herzfrequenzerhöhung und Blutdruckveränderungen. Die emotionale Reaktion ist individuell und hängt z. B. von Geräuschart, persönlicher Vorerfahrung, sozialem Kontext oder psychologischem Profil ab. Die Misophonie ist bisher als Krankheit nicht definiert und keinem offiziellen Diagnosesystem zugeordnet, sie scheint eine eigenständige Störung zu sein: Assoziationen bestehen u. a. mit Aufmerksamkeits‑/Zwangsstörungen, Tinnitus, Hyperakusis, Autismus-Spektrum-Krankheiten. Definitionskriterien wurden 2013 veröffentlicht; verschiedene, validierte Fragebögen wurden bisher zur Misophonieausprägung entwickelt. Studien mit funktionellen MRT-Untersuchungen des Kopfes zeigten eine übermäßige Aktivierung des anterioren Inselkortex (AIC) und seiner benachbarten Regionen, die für Emotionsverarbeitung/-regulation verantwortlich sind. Bisher gibt es keine randomisierten kontrollierten Studien zur Therapie. Einzelne Publikationen beschreiben kognitive Verhaltensinterventionen, Retrainingtherapien und Schallmaskierungssysteme. Zur Triggerreduktion werden Ohrstöpsel/Musikkopfhörer verwendet. Auch HNO-Ärzte können mit Misophoniepatienten konfrontiert werden, z. B. zur Klärung des Hörvermögens oder Beratung von Therapiemöglichkeiten. Der Bericht stellt eine Übersicht des aktuellen Wissensstands zur Misophonie sowie ihrer Diagnostik und Therapie dar.

Authors: Alfonso-Prieto Mercedes 
Published: June 2021

Abstract
The Up-and-Coming-Scientist section of the current issue of the Journal of Membrane Biology features the invited essay by Dr. Mercedes Alfonso-Prieto, Assistant Professor at the Forschungszentrum Jülich (FZJ), Germany, and the Heinrich-Heine University Düsseldorf, Vogt Institute for Brain Research.
Dr. Alfonso-Prieto completed her doctoral degree in chemistry at the Barcelona Science Park, Spain, in 2009, pursued post-doctoral research in computational molecular sciences at Temple University, USA, and then, as a Marie Curie post-doctoral fellow at the University of Barcelona, worked on computations of enzyme reactions and modeling of photoswitchable ligands targeting neuronal receptors. In 2016, she joined the Institute for Advanced Science and the Institute for Computational Biomedicine at the FZJ, where she pursues research on modeling and simulation of chemical senses.
The invited essay by Dr. Alfonso-Prieto discusses state-of-the-art modeling of molecular receptors involved in chemical sensing – the senses of taste and smell. These receptors, and computational methods to study them, are the focus of Dr. Alfonso-Prieto’s research. Recently, Dr. Alfonso-Prieto and colleagues have presented a new methodology to predict ligand binding poses for GPCRs, and extensive computations that deciphered the ligand selectivity determinants of bitter taste receptors. These developments inform our current understanding of how taste occurs at the molecular level.

Abstract
Objective
Tumor-related eosinophilia may have extended survival benefits for some cancer patients. However, there has been no report on the prognosis difference between eosinophilic pleural effusion (EPE) and non-EPE in lung cancer patients. Our study aimed to investigate the prognosis difference between EPE and non-EPE due to lung cancer.

Patients and methods
We retrospectively reviewed patients diagnosed with lung cancer who presented with malignant pleural effusion (MPE) between May 2007 and September 2020 at the National Hospital Organization Kochi Hospital. EPE is defined as pleural fluid with a nucleated cell count containing 10% or more eosinophils.

Results
A total of 152 patients were included: 89 were male (59%). The median age was 74.4 years (range 37–101), and all patients were pathologically shown to have MPE. Most patients (140; 92%) had an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0/1. Twenty patients had EPE. The median overall survival (OS) of all 152 lung cancer patients with MPE was 298 days. The median OS of the patients with EPE was 766 days, and the median OS of the patients with non-EPE was 252 days. Kaplan–Meier univariate analysis showed that lung cancer patients with EPE had a significantly better prognosis than patients with non-EPE (P < 0.05). Cox proportional regression analysis showed that EPE, ECOG PS, sex, and the neutrophil-to-lymphocyte ratio in the serum (sNLR) may be independent prognostic factors affecting survival in patients with MPE.

Conclusion
Lung cancer patients with EPE have a better prognosis than those with non-EPE.

Published: June 2021

Abstract
Purpose
To analyze the role of programmed death ligand 1 (PD-L1) immunohistochemisty in the context of tumor microenvironment in colon cancer (CC) with focus on the interaction between tumor budding and tumor-infiltrating lymphocytes (TILs) and to elucidate its potential value for immunooncologic treatment decisions.

Methods
Three hundred forty seven patients with CC, stages I to IV, were enrolled. PD-L1 immunohistochemistry was performed using two different antibodies (clone 22C3 pharmDx, Agilent and clone QR1, Quartett). Tumor proportion score (TPS) as well as immune cell score (IC) was assessed. Budding and TILs were assessed according to the criteria of the International Tumor Budding Consensus Conference (ITBCC) and International TILs Working Group (ITWG). Correlation analyses as well as survival analyses were performed.

Results
PD-L1 positivity significantly correlated with TILs > 5% and MMR deficiency, and PD-L1-positive cases (overall and IC) showed significantly longer overall survival (OS) with both antibodies.The parameters “high grade,” “right-sidedness,” and “TILS > 5% regardless of MMR status” evolved as potential parameters for additional immunological treatment decisions. Additionally, TPS positivity correlated with low budding. More PD-L1-positive cases were seen in both high TIL groups. The low budding/high TIL group showed longer disease-free survival and longer OS in PD-L1-positive cases.

Conclusion
Overall, PD-L1 positivity correlated with markers of good prognosis. PD-L1 immunohistochemistry was able to identify parameters as additional potential candidates for immune therapy. Furthermore, it was able to stratify patients within the low budding/high TIL group with significant prognostic impact.

Published: June 2021

Abstract
Background
Biomarkers of fibrosis are associated with outcome in several cardiovascular diseases. However, their relevance to chronic kidney disease and dialysis is uncertain, as it remains unclear how the kidneys and the dialysis procedure itself affect their elimination and degradation. We aimed to investigate the relationship of the blood levels of two markers associated with fibrosis: procollagen type I C-terminal pro-peptide (PICP) and galectin-3 (Gal-3) with mortality in dialysis patients.

Methods
Procollagen type I C-terminal pro-peptide and galectin-3 were measured at baseline in 2773 patients enrolled in the AURORA trial, investigating the effect of rosuvastatin on cardiovascular outcomes, in patients on hemodialysis, and their interaction with CV death or all-cause mortality using survival models. The added prognostic value of these biomarkers was assessed by the net reclassification improvement (NRI).

Results
The median follow-up period was 3.8 years. Blood concentrations of PICP and Gal-3 were significantly associated with CV death [adjusted HR per 1 SD = 1.11 (1.02–1.20) and SD = 1.20 (1.10–1.31), respectively] and all-cause mortality (all adjusted p < 0.001). PICP and Gal-3 had a synergistic effect with regard to CV death and all-cause mortality (interaction p = 0.04 and 0.01, respectively). Adding PICP, Gal-3 and their interaction on top of clinical and biological covariates, resulted in significantly improved prognostic accuracy NRI = 0.080 (0.019–0.143) for CV death.

Conclusion
In dialysis patients, concomitant increase in PICP and Gal-3 concentrations are associated with higher rates of CV death. These results suggest that concomitantly raised PICP and Gal-3 may reflect an activated fibrogenesis relevant to risk stratification in dialysis, raising the hypothesis that anti-fibrotic therapy may be beneficial for cardiovascular protection in such patients.

SEC61G identified as a prognostic biomarker of head and neck squamous cell carcinoma
Authors: Shi Yanan , Liang Yibo , Wang Wei , Zhang Guimin 
Published: June 2021

Abstract
Purpose
It is of obvious interest to identify clinical prognosis-related oncogenes in HNSCC (head and neck squamous cell carcinoma).

Methods
Based on the available datasets within the TCGA (The Cancer Genome Atlas) and the GEO (Gene Expression Omnibus) databases, the potential mechanism of action of the SEC61G (SEC61 translocon subunit gamma) gene in HNSCC tumorigenesis was explored by several bioinformatics approaches.

Results
There was a higher expression level of SEC61G in primary HNSCC tumor tissues than in normal tissues. Moreover, highly expressed SEC61G was statistically associated with the poor survival prognosis of HNSCC patients. When HPV (human papilloma virus) was considered, we also observed a relatively lower proportion of “arm-level gain” and “high amplification” types of CNA (copy-number alteration) in the HNSCC-HPV (+) group than in the HNSCC-HPV (−) group. Additionally, we identified SEC61G CAN-correlated genes, such as CCT6A (chaperonin-containing TCP1 subunit 6A) and HUS1 (HUS1 checkpoint clamp component), and found a correlation between SEC61G copy-number segments and prognosis related to overall and progression-free survival intervals of HNSCC patients. Moreover, the molecular regulation mechanisms of the spliceosome, ribosome, proteasome degradation, cell adhesion, and immune infiltration of B and CD8+ T cells may contribute to the involvement of SEC61G in the pathogenesis of HNSCC.

Conclusions
The SEC61G gene was identified for the first time as a prognostic biomarker of HNSCC. The detailed underlying mechanism merits further research.
On the choice of methodology for evaluating dose-rate effects on radiation-related cancer risks
Authors: Walsh Linda , Shore Roy , Azizova Tamara V. , Rühm Werner 
Published: June 2021

AbstractRecently, several compilations of individual radiation epidemiology study results have aimed to obtain direct evidence on the magnitudes of dose-rate effects on radiation-related cancer risks. These compilations have relied on meta-analyses of ratios of risks from low dose-rate studies and matched risks from the solid cancer Excess Relative Risk models fitted to the acutely exposed Japanese A-bomb cohort. The purpose here is to demonstrate how choices of methodology for evaluating dose-rate effects on radiation-related cancer risks may influence the results reported for dose-rate effects. The current analysis is intended to address methodological issues and does not imply that the authors recommend a particular value for the dose and dose-rate effectiveness factor. A set of 22 results from one recent published study has been adopted here as a test set of data for applying the many different methods described here, that nearly all produced highly consistent results. Some recently voiced concerns, involving the recalling of the well-known theoretical point—the ratio of two normal random variables has a theoretically unbounded variance—that could potentially cause issues, are shown to be unfounded when aimed at the published work cited and examined in detail here. In the calculation of dose-rate effects for radiation protection purposes, it is recommended that meta-estimators should retain the full epidemiological and dosimetric matching information between the risks from the individual low dose-rate studies and the acutely exposed A-bomb cohort and that a regression approach can be considered as a useful alternative to current approaches.

Published: June 2021

Abstract
Introduction
Studies have reported autonomic impairment in patients with idiopathic REM sleep behaviour disorder (iRBD), which is considered a prodromal stage of alpha-synucleinopathies. It is still debated whether central or peripheral pathologies are first manifestations of alpha-synucleinopathies. This study aimed to characterize autonomic and somatosensory function in iRBD patients.

Methods
This cross-sectional prospective case–control study included 17 iRBD patients (mean age 66.3 ± 9.2 years) and 16 healthy controls (HCs, 66.6 ± 11.3 years). Quantitative sensory testing, neurological and neuropsychological assessments, norepinephrine blood plasma levels, tilt table examination with orthostatic blood pressure, and heart rate variability were carried out. Longitudinal data of 10 iRBD patients, including neurological, neuropsychological, and tilt table examination, were assessed.

Results
iRBD patients more frequently presented with orthostatic dysfunction than HCs (70.6% vs. 6.3%, p < 0.0001). Supine norepinephrine plasma levels were normal, but lower in iRBD (249.59 ± 99.78 pg/ml iRBD, 354.13 ± 116.38 pg/ml HCs, p < 0.05). Quantitative sensory testing revealed impaired cold (CDT) and vibration detection thresholds (VDT) on the foot in iRBD (CDT foot iRBD − 1.24 ± 0.31, HCs − 9.89E-17 ± 0.25, VDT iRBD − 1.11 ± 0.47, HCs − 1.46E-16 ± 0.25, p < 0.05). Cold detection thresholds differed between the foot and hand among iRBD patients (foot − 1.24 ± 0.31, hand − 0.56 ± 0.25, p < 0.05). Longitudinal data revealed an increase in maximum systolic and diastolic orthostatic blood pressure changes and a decrease in the Valsalva ratio in the follow-up group (p < 0.05).

Conclusion
This study revealed autonomic dysfunction with somatosensory impairment, and decreased norepinephrine levels in iRBD, which may serve as a possible prodromal marker for developing alpha-synucleinopathy.
Ökonomisierung im Gesundheitswesen als organisationsethische Herausforderung
Authors: Marckmann Georg 
Published: June 2021

ZusammenfassungDer finanzielle Druck auf die Krankenhäuser in Deutschland führt zu einer Ökonomisierung medizinischer Entscheidungen, die die Qualität der Patientenversorgung beeinträchtigt und das Gesundheitspersonal erheblich belastet. Der vorliegende Beitrag untersucht, welche Möglichkeiten ein organisationsethischer Ansatz bietet, den Herausforderungen durch die Ökonomisierung zu begegnen. Ausgewählte empirische Befunde sollen zunächst verdeutlichen, welche Auswirkungen die Ökonomisierung auf die Patientenversorgung und das Personal in den Krankenhäusern hat. Zudem liefern sie erste Hinweise auf mögliche Handlungsspielräume für die Krankenhäuser. Dabei wird deutlich, dass die Ökonomisierung einen organisationsethischen Ansatz erfordert, der die Handlungsspielräume auf der Mesoebene, d. h. auf der Ebene der einzelnen Krankenhäuser nutzt. Der organisationsethische Ansatz wird in seinen Grundzügen vorgestellt und dann im Sinne eines Wertemanagements als Lösungsperspektive für die Herausforderungen der Ökonomisierung konkretisiert. Abschließend entwickelt der Beitrag Perspektiven, wie klinische Ethikkomitees mit organisationsethischer Arbeit den negativen Auswirkungen der Ökonomisierung auf die Patientenversorgung und das Personal im Krankenhaus entgegenwirken können.

Published: June 2021

AbstractThe recently described red alga Tsunamia transpacifica (Stylonematophyceae) was previously isolated from plastic drift found at the pacific coast, but the natural habitat remains unknown. Here, we investigate ultrastructural details and the low molecular weight soluble carbohydrate composition to get further insight into the adaptation to this uncommon habitat. By means of high pressure freeze fixation, followed by freeze substitution, we could detect an up to 2-µm-thick cell wall surrounded by a distinct layer of extracellular polymeric substances (EPS), likely responsible for the adhering capacities of Tsunamia. The central position of the nucleus and multilobed parietal chloroplast, already observed by light microscopy, could be confirmed. The ultrastructure revealed large electron-dense bodies (EB) in the central cytoplasm, likely resembling degradation products of the chloroplast. Interestingly, these structures contained phosphorous and cobalt, and iron was found in smaller rounded electron-dense bodies by electron energy loss spectroscopy (EELS). Accumulation of these elements suggests a high biosorption activity of Tsunamia. Liquid chromatography-mass spectrometry (LC–MS) data showed the presence of two heterosides (floridoside and digeneaside) together with the polyol sorbitol, which are known as organic osmolytes and compatible solutes. Taken together, these are the first observations on ultrastructural details, element storage and accumulation of protective compounds are contributing to our understanding of the ultrastructural and osmotic solute basis for the ability of Tsunamia to thrive on plastic surfaces.
Damping prediction of particle dampers for structures under forced vibration using effective fields
Authors: Meyer Niklas , Seifried Robert 
Published: June 2021

AbstractParticle damping is a promising damping technique for a variety of technical applications. However, their non-linear behavior and multitude of influence parameters, hinder currently its wide practical use. So far, most researchers focus either on determining the energy dissipation inside the damper or on the overall damping behavior when coupled to a structure. Indeed, currently almost no knowledge exchange between both approaches occurs. Here, a bridge is build to combine both techniques for systems under forced vibrations by coupling the energy dissipation field and effective particle mass field of a particle damper with a reduced model of a vibrating structure. Thus, the overall damping of the structure is estimated very quickly. This combination of both techniques is essential for an overall efficient dimensioning process and also provides a deeper understanding of the dynamical processes. The accuracy of the proposed coupling method is demonstrated via a simple application example. Hereby, the energy dissipation and effective mass of the particle damper are analyzed for a large excitation range first using a shaker setup. The particle damper exhibits multiple areas of different efficiency. The underlying structure is modeled using FEM and modal reduction techniques. By coupling both parts it is shown that multiple eigenmodes of the structure are highly damped using the particle damper. The damping prediction using the developed coupling procedure is validated via experiments of the overall structure with particle damper.

Abstract
Introduction
COVID-19 pandemic radically transformed our daily clinical practice, raising the need not to lose close contact with patients without being able to see them face-to-face. These issues are even more felt and evident in fragile patients, as those affected by neuromuscular disease. An important help came from new digital technologies that allow clinicians to remotely monitor health status and any deterioration of chronically ill patients.

Methods
In this mini-review, an initiative of the “Digital Technologies, Web and Social Media Study Group” of the Italian Society of Neurology, we propose to analyze the approach to neuromuscular patients by looking over raising evidence on the main cornerstones of Telemedicine (TM): clinician-patient interaction, remote clinical assessment, remote monitoring, and digital therapeutics. In particular, we explored the strategies developed by researchers and their impact on the physical and emotional status of the patients, with particular focusing on their adherence to the program of virtual monitoring.

Results
TM plays an important role in each of four stages of approach to neuromuscular disease, having demonstrated validity in keep close clinical patient interaction, clinical assessment, remote monitoring, and telerehabilitation. Nevertheless, there is no remote alternative to electrophysiological testing neither validate tools to assess disability.

Conclusion
The role of TM in neuromuscular care is yet underestimated but is crucial, beyond the pandemic era. Further development of TM is advisable, through making specific apps, remotely controlled by clinicians, and making more engaging clinicians-patients interaction. Last, it is necessary to ensure adequate internet access to everyone.
