Published: October 2021

Zusammenfassung
Hintergrund
Gerade in der Notfallmedizin ist der schnelle Zugriff auf Informationen anderer Leistungserbringer von besonderer Bedeutung, da die Patienten oftmals unbekannt sind und Behandlungsentscheidungen zeitnah getroffen werden müssen.

Ziel der Arbeit
Die Studie zielt darauf ab, herauszufinden, mit welchen Herausforderungen die Notaufnahmen bei der Informationsbeschaffung konfrontiert sind, wie hoch der erwartete Nutzen eines einfacheren Informationszugangs ist und welche Informationen zur Patientenvorgeschichte dort am dringendsten benötigt werden.

Material und Methoden
Durchgeführt wurde eine deutschlandweite Online-Befragung unter in Notaufnahmen tätigem medizinischem Personal. 181 Fragebögen wurden vollständig ausgefüllt und konnten in die Datenanalyse einbezogen werden.

Ergebnisse
Insgesamt 77,9 % des befragten Notaufnahmepersonals bewertete es als schwierig oder sehr schwierig, im Rahmen der Patientenversorgung an klinische Informationen von außen zu gelangen. Im Durchschnitt benötigen die Befragungsteilnehmer ihren Schätzungen zufolge rund 47 min, um an Informationen zu einem Patienten zu gelangen. 99,4 % gehen davon aus, dass die Patientenversorgung von einem einfacheren und schnelleren Informationsaustausch profitieren würde. Als wichtigste Datenelemente wurden Medikationslisten, Entlassungsbriefe und Informationen zu Vorerkrankungen sowie Allergien eingestuft.

Diskussion
In Anbetracht des erheblichen Aufwandes für die Informationsbeschaffung bei Notfallpatienten besteht ein dringlicher Handlungsbedarf. Digitale Lösungen wie der gerade eingeführte Notfalldatensatz können bei flächendeckender Verbreitung hier einen Mehrwert für die klinische Notfallversorgung bieten.
A novel identification technique of machine tool support stiffness under the variance of structural weight
Authors: Zhuang Zhen-Wei , Lu Jen-Chang , Liu De-Shin 
Published: October 2021

AbstractThe preload-dependent stiffness of machine tool support was investigated in this study. A novel identification method of support stiffness has been proposed through the experimental modal analysis and finite element method. The support stiffness was identified with different machine weight during the assembling process of a machining center. Specifically, the structure weight increase of a machine tool in the assembly process causes its center of gravity to shift. Accordingly, the variance of support reaction affects the support stiffness. To explore the variance of support stiffness, the researchers of this study collaborated with a machine tool manufacturer. Impact testing was performed on each assembly stage. Additionally, finite element analysis was used to establish equations between the reaction force versus stiffness of supports under the structural weight variance. The obtained equations were used to predict the natural frequency and vibration mode of structures in various assembly stages. The maximum error between the experimental and simulated natural frequencies was 7.1%, and the minimum modal assurance criterion was 0.77. Finally, a modal analysis model that updates support stiffness automatically, which could be adopted by machine builders to develop new machine tool, is proposed.

Abstract
Introduction
We present a case of dual drainage of the right upper lobe of the lung into the left atrium and via partial anomalous venous pulmonary return (PAPVR) into a persistent left superior vena cava (SVC).

Discussion
It is only in the minority of PAPVR cases where the anomalous pulmonary veins cross the midline. We provide a review of current literature on this topic and an explanatory embryological model. Knowledge of embryonic development and possible anatomic variations, including the concept of dual venous drainage of the lung, leads to better interpretation of imaging, with more accurate description of the morphology at hand. High-resolution multidetector computed tomography (MDCT) helps to delineate the exact vascular anatomy. This will enhance a better understanding of and anticipation on the patient’s disease status, with more accurate planning of intervention, and possibly less complications.

AbstractEncephalopathy is a neurological complication of COVID-19. The objective of this exploratory study is to investigate the link between systemic inflammation and brain microstructural changes (measured by diffusion-weighted imaging) in patients with COVID-19 encephalopathy. 20 patients with COVID-19 encephalopathy (age: 67.3 $$\pm$$
±
10.0 years; 90% men) hospitalized in the Geneva University Hospitals for a SARS-CoV-2 infection between March and May 2020 were included in this retrospective cohort study. COVID-19 encephalopathy was diagnosed following a comprehensive neurobiological evaluation, excluding common causes of delirium, such as hypoxemic or metabolic encephalopathy. We investigated the correlation between systemic inflammation (measured by systemic C-reactive protein (CRP)) and brain microstructural changes in radiologically normal white matter (measured by apparent diffusion coefficient (ADC)) in nine spatially widespread regions of the white matter previously associated with delirium. Systemic inflammation (CRP = 60.8 ± 50.0 mg/L) was positively correlated with ADC values in the anterior corona radiata (p = 0.0089), genu of the corpus callosum (p = 0.0064) and external capsule (p = 0.0086) after adjusting for patients’ age. No statistically significant association between CRP and ADC was found in the other six white matter regions. Our findings indicate high risk of white matter abnormalities in COVID-19 encephalopathy patients with high peripheral inflammatory markers, suggesting aggressive imaging monitoring may be warranted in these patients. Future studies should clarify a possible specificity of the spatial patterns of CRP–white matter microstructure association in COVID-19 encephalopathy patients and disentangle the role of individual cytokines on brain inflammatory mechanisms.

Abstract
Background
Esophageal cancer surgery requires maintenance and enhancement of perioperative nutritional status and physical function to prevent postoperative complications. Therefore, awareness of the importance of preoperative patient support is increasing. This study examined the usefulness of using a diary in combination with a wearable fitness tracking device (WFT) in patients undergoing surgery for esophageal cancer.

Methods
Ninety-four patients who underwent esophagectomy between February 2019 and April 2021 were included. Physicians, nurses, dietitians, and physical therapists provided diary-based education for the patients. In addition, a WFT was used by some patients. The perioperative outcomes of patients who used both the diary and WFT (WFT group) and those who used the diary alone (non-WFT group) were compared. In addition, propensity score matching was performed to improve comparability between the two groups.

Results
After the propensity score matching, the rate of postoperative pneumonia was significantly lower in the WFT group (0% vs. 22.6%, P = 0.005). The postoperative hospital stay was shorter in the WFT group (P = 0.012). Nutritional status indices, such as the prognostic nutritional index, also improved significantly in the WFT group at 1 month after surgery (P = 0.034). The rate of diary entries was significantly higher in the WFT group (72.3% vs. 28.3%, P < 0.001).

Conclusion
The use of a WFT reduced the incidence of postoperative pneumonia and improved postoperative nutritional status and rates of diary entries after esophagectomy, suggesting that its use may be useful for promoting recovery after esophagectomy.
Sexualität von Schüler*innen im Sportunterricht
Authors: Böhlke Nicola , Zander Benjamin 
Published: October 2021

ZusammenfassungSchule ist kein asexueller Sozialraum. Gerade das Fach Sport dürfte aufgrund seiner Körperzentrierung vielfältige Bezüge zur Sexualität bieten, was aber bislang kaum untersucht wurde. Im Beitrag wird der zentralen Frage nachgegangen, wie sich die Sexualität von Schüler*innen im Sportunterricht als ein diskursives Phänomen konstituiert. Hierzu wurde eine qualitative Diskursanalyse durchgeführt, die sich auf Onlineforen stützt und Datenmaterial aus dem Zeitraum 2007–2021 berücksichtigt. Die Befunde, die mit den Analyseverfahren der Grounded Theory herausgearbeitet wurden, zeigen, dass Sexualität im Sportunterricht als ein diskursives Phänomen äußert facettenreich ist, so an Themen wie Kleidung, Körpernähe oder Koedukation gebunden ist und dabei als hierarchisches Geschehen im Zusammenhang der Rollen von Lehrer*innen und Schüler*innen, als emotionales Geschehen in Verbindung mit Scham, Empörung, Ekel, Neugierde oder Lust, aber auch als alltägliches wie omnipräsentes Geschehen kontextualisiert wird. In einer differenzierten Beschreibung des Phänomens werden themenübergreifend die zentralen Ursachen (insbesondere die starke Normierung des Phänomens), Konsequenzen (zum Beispiel soziale Verurteilungen als Folge von Verhaltensweisen, durch die sich andere belästigt fühlen) und Strategien des Umgangs mit Sexualität (zum Beispiel das Verstecken der Erektion bzw. der Brüste) herausgestellt. Auf Basis der Phänomenbeschreibung wird die Sexualität von Schüler*innen als ein Drahtseilakt deutlich, der darin besteht, teils divergierende Normen gekonnt auszutarieren, was zukünftig von der Schulsportforschung tiefergehend zu untersuchen ist.

AbstractThis study is about the use of naturally occurring filtering materials for rainwater treatment for drinking water proposal. Crushed gravel, ceramic spheres from natural clays, silica sand and natural zeolite were used as filtering materials. The mineralogical composition of filtering materials was determined, being the illite and mordenite the major components of ceramic spheres and natural zeolite, respectively. Naturally occurring materials were simultaneous evaluated on two configuration of pilot plant systems (biofilters) for rainwater treatment. Three columns were arranged in series with unstratified flooded beds. The first stage was packed using crushed gravel. The second stage was packed using ceramic spheres. The third stage was packed with silica sand for the first plant and a natural zeolite was used for the second pilot plant system. Finally, a last stage of ultraviolet disinfection was incorporated. The trial period was 90 days, and it was evaluated the removal of Fe+2 and Mn+2, total coliforms, faecal coliforms and Escherichia col (E. coli). The rainwater treatment system using natural zeolite provided better results than the one using silica sand at third stage. The concentration of Fe+2 and Mn+2 was below the maximum permissible limits within 45 days. The efficiency of the treatment systems was optimal within 45 days, after the efficiency decreased progressively. Then, it is an attractive proposal for rural areas in developing countries for single-family water treatment systems.
Chemie finde ich eigentlich interessant, aber manchmal auch nicht – Zusammenhänge zwischen Merkmalen des Chemieunterrichts und dem situationalen Interesse von Lernenden

Published: October 2021

ZusammenfassungInteresse ist ein wichtiges unterrichtliches Ziel und positiv mit weiteren Konstrukten wie Leistung und Selbstkonzept assoziiert. Eine Abnahme des Interesses von Lernenden in den Naturwissenschaften allgemein und insbesondere im Chemieunterricht über den Verlauf der Sekundarstufe wurde wiederholt festgestellt. Um Interesse im Schulkontext zu fördern, bietet sich gemäß des Vier-Phasen Modells der Interessenentwicklung insbesondere das zeitlich instabile situationale Interesse an. Die Befundlage zu möglichen Triggern für situationales Interesse ist sehr vielfältig, jedoch teilweise uneindeutig. Zudem werden bislang in den Untersuchungen zum situationalen Interesse zentrale Qualitäts- und Gestaltungsmerkmale von Unterricht wie die Klassenführung oder Unterrichtsphasierung nicht systematisch berücksichtigt. Dieses Desiderat adressiert die vorliegende Beobachtungsstudie im Fach Chemie, indem sie den Zusammenhang zwischen Unterrichtsqualität sowie -gestaltung mit dem situationalen Interesse von Lernenden der Sekundarstufe I mittels einer Mehrebenenanalyse untersucht. Die Ergebnisse bestätigen empirisch, dass in der vorliegenden Studie praktische Erarbeitungsphasen in positiver Relation zum situationalen Interesse der Lernenden stehen, während theoretische Erarbeitungsphasen damit negativ verknüpft sind. Einstiegs- und Sicherungsphasen weisen keinen systematischen Zusammenhang mit dem situationalen Interesse auf. Im Bereich der Unterrichtsqualität zeigen sich negative Zusammenhänge zwischen dem situationalen Interesse und Klassenmanagement bzw. Verständnisorientierung, während zwischen dem situationalen Interesse und Strukturierung bzw. Förderung positive Zusammenhänge festgestellt wurden. Mögliche Ursachen sowie Implikationen für Forschung und Praxis werden diskutiert.
Hierarchical Sizing and Power Distribution Strategy for Hybrid Energy Storage System
Authors: Li Jianwei , He Hongwen , Wei Zhongbao , Zhang Xudong 
Published: October 2021

AbstractThis paper proposes a hierarchical sizing method and a power distribution strategy of a hybrid energy storage system for plug-in hybrid electric vehicles (PHEVs), aiming to reduce both the energy consumption and battery degradation cost. As the optimal size matching is significant to multi-energy systems like PHEV with both battery and supercapacitor (SC), this hybrid system is adopted herein. First, the hierarchical optimization is conducted, when the optimal power of the internal combustion engine is calculated based on dynamic programming, and a wavelet transformer is introduced to distribute the power between the battery and the SC. Then, the fuel economy and battery degradation are evaluated to return feedback value to each sizing point within the hybrid energy storage system sizing space, obtaining the optimal sizes for the battery and the SC by comparing all the values in the whole sizing space. Finally, an all-hardware test platform is established with a fully active power conversion topology, on which the real-time control capability of the wavelet transformer method and the size matching between the battery and the SC are verified in both short and long time spans.
Arbitration in Syria: Navigating Postwar Disputes
Authors: Nasrallah Faris Elias 
Published: October 2021

AbstractThe place of arbitration within the Syrian legal system has received scant academic and professional attention, and as such, remains largely unstudied. Shedding much-needed light on the nature of arbitration in Syria as a resilient form of ancient customary Arab alternative dispute resolution, this contribution appraises the salient features of the Syrian Arbitration Law 2008 and arbitration-related provisions within recent Syrian legislation. It aims to understand the position of arbitration in Syria between existing national and international law frameworks for dispute settlement and to assess the potential for establishing independent, transparent, and efficient tribunals to resolve disputes arising out of ongoing conflicts that have plagued the country since 2011. If arbitration proves to be a mechanism for ordering the peaceful settlement of postwar disputes within and concerning Syria, parties, practitioners, and stakeholders must employ perspectives that include and are capable of navigating Syria’s existing arbitration landscape.
Earthquake Nucleation Along Faults With Heterogeneous Weakening Rate

Published: October 2021

AbstractThe transition from quasistatic slip growth to dynamic rupture propagation constitutes one possible scenario to describe earthquake nucleation. If this transition is rather well understood for homogeneous faults, how the friction properties of multiscale asperities may influence the overall stability of seismogenic faults remains largely unclear. Combining classical nucleation theory and concepts borrowed from condensed matter physics, we propose a comprehensive analytical framework that predicts the influence of heterogeneities of weakening rate on the nucleation length for linearly slip‐dependent friction laws. Model predictions are compared to nucleation lengths measured from 2D dynamic simulations of earthquake nucleation along heterogeneous faults. Our results show that the interplay between frictional properties and the asperity size gives birth to three instability regimes (local, extremal, and homogenized), each related to different nucleation scenarios, and that the influence of heterogeneities at a scale far lower than the nucleation length can be averaged.
A Comprehensive Search for Repeating Earthquakes in Northern California: Implications for Fault Creep, Slip Rates, Slip Partitioning, and Transient Stress
Authors: Waldhauser Felix , Schaff David P. 
Published: October 2021

AbstractRepeating earthquakes, earthquakes that rupture the same fault patch more than once, are playing an important role in the study of source processes and fault behavior, and have the potential to improve hazard assessment and earthquake forecast. They are believed to represent brittle failure of a stuck patch (asperity) on an otherwise creeping fault, and as such may offer insight into slip behavior at depth. We carried out a systematic analysis in search for repeating earthquakes in northern California between 1984 and 2014 by identifying events that are co‐located, are of similar size, and share similar waveforms. We find 27,675 events in 7,713 repeating earthquake sequences (RES) that include between 2 and 32 events with magnitudes between −0.5 and 6.5. Temporal behavior of the events within each RES ranges between random and quasi‐periodic over the 30‐year observation period, and includes temporal clustering (bursts). The RESs occur throughout northern California, with some of the largest and most periodic sequences predominately, but not exclusively, along faults within the San Andreas Fault system that exhibit surface creep. Piecewise periodic RESs are found near large earthquakes where they are modulated by transient stress. Slip rates inferred from the new data, while generally consistent with published estimates from geodetic and surface data, offer a high‐resolution image of subsurface creep along individual fault strands and resolve slip partitioning across wider zones of deformation.

Published: October 2021

Objective: This study aims to assess stress, quality of life, and mental health risk experienced by parents of children with short bowel syndrome (SBS) undergoing intestinal rehabilitation compared to a group of parents of children with common gastrointestinal complaints. Method: Eleven parents of racially/ethnically diverse children with SBS (0–5 years old) were recruited from a multidisciplinary intestinal rehabilitation program in the southeastern United States. Participants completed sociodemographic, mental health risk (PHQ-SADS), parental stress (PSI-4 Short Form), and quality of life (QoL; SF-36) questionnaires. Semistructured interviews of SBS parents were conducted, transcribed, coded, and systematically analyzed using principals of thematic analysis. Results: Significant differences with large effect sizes were found on measures of anxiety, parenting stress, and emotional well-being, indicating greater risk for SBS parents. Parent experiences in three themes were identified: navigating treatment challenges (e.g., high risk of complications), parenting role stress (e.g., respite and self-care), and support systems (e.g., peer-based support). Parents reported a lack of awareness and education surrounding intestinal rehabilitation and SBS, resulting in difficulty accessing quality medical treatment, services, and support. Conclusions: Semistructured interviews provided rich information to better understand SBS parent challenges and generated hypotheses about specific recommendations aimed at improving parent quality of life, health outcomes, and satisfaction with care, as well as the need for integration of mental health screening and evidence-based interventions that address the specific needs of parents. Implications for Impact Statement The present study finds significant risk of anxiety, parenting stress, and emotional problems in parents of children with short bowel syndrome undergoing intestinal rehabilitation. Interviews with parents highlight the challenges involved in navigating treatment, managing parenting stress, and helpful support systems. Pediatric psychologists are well positioned to help improve the quality of care and access to needed supports for parents of children with these complex medical needs.
