Published: July 2024

Historically, Sweden has reported several impacts on transformers and transmission lines related to geomagnetically induced currents (GICs) that develop during strong space weather events. GICs are driven by the geoelectric field (E), and their intensity depends on various factors, including the lithology conductivity and the rate of change of the Earth’s magnetic field. The purpose of this study is to perform an extreme value (EV) analysis of the E magnitude at six different latitudes in Sweden and to express the maximum |E| that might be observed in 10, 50, and 100 years. We analyzed 10-s E data in Sweden, obtained from a 1-D model. This model incorporates 10-s geomagnetic measurements from the IMAGE network and the vertical Earth’s ground electrical conductivity in Sweden, extracted from a 3-D conductance map for the Fennoscandian region. Extreme E events tend to occur in clusters around geomagnetic disturbances (substorms and geomagnetic storms). Therefore, we applied two different methods to decluster the data. After declustering, Generalized Pareto (GP) distributions were fitted to the remaining extreme events that exceeded the 99.5th percentile. The EV analysis indicates that the shape parameter of the GP distribution depends on latitude. This implies that at higher geographic latitudes (64.52–68.02°N) the distribution decreases faster toward zero than at lower latitudes (58.26–62.25°N). As a result the expected maximum |E| in 100 years in central Sweden ranges between 4.0 and 8.5 V/km, while at higher latitudes, it ranges between 2.0 and 2.5 V/km, similar to the modeled geoelectric field values during the Halloween event in October 2003. In particular, around 60.50°N the distribution of extreme events exhibits the heaviest tail. When we additionally consider the effect of conductivity, the region of west Sweden around 60.50°N exhibits the largest expected maximum in 100 years with a value around 8.5 V/km. This is three times larger than the maximum modeled |E| at that latitude.

Zusammenfassung
Einleitung Die personbezogenen und Umweltfaktoren der ICF- Kontextfaktoren
sind als Einflussfaktoren auf körperliche und psychische Gesundheit, und auch
die (berufliche) Teilhabe zu verstehen. Bislang ist nicht geklärt, inwiefern
diese Kontextfaktoren in der sozialmedizinischen Begutachtung entsprechende
Berücksichtigung finden. Die umfangreichere Berücksichtigung der
ICF-Kontextfaktoren in der sozialmedizinischen Begutachtung könnte die Zuweisung
zu Erwerbsminderungsrente und rehabilitativen Maßnahmen individueller und
gezielter machen. In dieser Studie soll die Häufigkeit der ICF-Kontextfaktoren
in sozialmedizinischen Gutachten ermittelt werden.
Methodik Durchgeführt wurde eine Häufigkeitsanalyse der ICF-
Kontextfaktoren in sozialmedizinischen Gutachten bei muskuloskelettalen
Erkrankungen. Mehrfach genannte Kontextfaktoren wurden ein einziges Mal im
Gutachten kodiert. In einem Häufigkeitsranking wurden die einzelnen umwelt- und
personbezogenen Faktoren in die Kategorien „häufig“, „mittel“ und „selten“
eingeteilt.
Ergebnisse 215 sozialmedizinische Gutachten mit muskuloskelettalen
Diagnosen aus dem Jahr 2017 bildeten den Gegenstand der retrospektiven
Untersuchung. Alle Gutachten wurden auf das Auftreten von personenbezogenen und
Umweltfaktoren analysiert. Es wurden vor allem personbezogene Faktoren
nachgewiesen, welche Auskunft über allgemeine Merkmale zur Person oder den
allgemeinen Gesundheitszustand geben. Knapp die Hälfte der Umweltfaktoren wurde
selten identifiziert.
Schlussfolgerung Viele ICF-Kontextfaktoren werden zuverlässig in den
analysierten Gutachten erfasst. Die Bedeutung dieser Faktoren auf die Rückkehr
in das Erwerbsleben ist bekannt. Überraschend war das Fehlen oder geringe
Vorhandensein von ICF-Kontextfaktoren aus den Kapiteln Einstellungen (i4),
Gewohnheiten (i4) und Unterstützung & Beziehung (e3), die auch im Kontext
zum Erleben der Arbeitswelt der begutachteten Person stehen. Die Relevanz der
häufig und selten identifizierten ICF- Kontextfaktoren für die
sozialmedizinische Begutachtung bei muskuloskelettal-erkrankten
Rentenantragstellenden muss hinterfragt werden.

Abstract
Objective The ReLink project aims to reintegrate diagnosed-but-untreated hepatitis-C-positive patients into medical care and initiate a therapy.
Material/methods A retrospective search within the practice management system of a single center in Germany identified among 1965 hepatitis-C-positive patients 100 untreated patients with available contact details and meeting all inclusion criteria. Patients were contacted by 2 contact rounds.
Results Out of 100 patients, 64% were male. Most patients (81%) were aged between 30 and 59 years. The patients belonged to high-risk groups for hepatitis C virus infections or had other comorbidities. The majority of patients injected drugs (21%) and/or were currently or had been on substitution therapy (44%); alcohol addiction was also frequent (21%). Out of 25 patients who agreed to an appointment, 10 patients (40%) started therapy and 5 additional patients (20%) agreed to therapy but were not yet able to start or had not yet made a decision. One‑third of patients who agreed to an appointment did not show up.
Conclusions Diagnosed-but-untreated patients are an important subgroup of hepatitis-C-positive patients; their recall to the clinic for direct-acting antiviral therapy is possible. However, inaccurate contact information, unresponsiveness to outreach, and further reluctance to attend doctor appointments limited the overall impact of this program. Regular review of the patients’ contact details may facilitate both follow-up and recall.
Versorgungsrealität der Gastroparese in Deutschland – eine Umfrage der Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte (ALGK)

Published: July 2024

Zusammenfassung
Einleitung Die Behandlung der Gastroparese kann im klinischen Alltag schwierig sein. Ziele der vorliegenden anonymen Befragung der Mitglieder der Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte e.V. (ALGK) war eine Erhebung der Versorgungsrealität der Gastroparese in Deutschland.
Material und Methoden Die ALGK führte über 40 Tage 2023 eine Mitgliederbefragung anhand eines standardisierten anonymisierten Fragebogens mit 11 Fragen durch. Diese bezogen sich auf diagnostische und therapeutische Maßnahmen sowie verschiedene Aspekte des allgemeinen Managements der Gastroparese.
Ergebnisse Die Rücklaufquote betrug 21,4%. Nur 6,56% aller Befragten beurteilten die Prävalenz dieses Krankheitsbilds näherungsweise so, wie es aktuelle Publikationen vermuten lassen. Zur definitiven Diagnosestellung nutzten 68,85% aller Befragten die Magenentleerungsszintigrafie. Für 51,61% war das wichtigste Behandlungsziel eine individuelle Therapie unter Berücksichtigung von Ursache und Beschwerdeintensität der Erkrankung, für 43,55% die symptomatische Behandlung des dominierenden Kardinalsymptoms. Therapie der ersten Wahl waren für 41,94% Medikamente, für 27,42% Ernährungsempfehlungen und für 24,2% endoskopische Eingriffe. Bei der Auswahl der Medikamente nutzten 100% Prokinetika, 40,32% Antiemetika. Analgetika wurden nur von 4,84% eingesetzt. Handlungsbedarf sehen 85,48% in der unzureichenden Verfügbarkeit medikamentöser Therapieoptionen, 48,39% in der fehlenden aktuellen Zulassungssituation verfügbarer Medikamente für die Indikation Gastroparese. Relativ häufig wurden von den Befragten Behandlungsoptionen durchgeführt, für die nur geringe Evidenz besteht (z.B. Einsatz pflanzlicher Heilmittel in 43,55%).
Diskussion Insgesamt wurde in der aktuellen Umfrage die Häufigkeit der Gastroparese unterschätzt. Endoskopische Optionen werden nicht selten auch als Therapie der ersten Wahl eingesetzt. Obwohl eine Symptomen–orientierte Behandlung für einen Großteil der Befragten wichtig ist, werden bei der Medikamentenauswahl vor allem Prokinetika angewendet.

Published: July 2024

AbstractAging-related changes in the skin, such as dullness, dehydration, and loss of elasticity, significantly affect its appearance and integrity. Injectable “skin boosters,” comprising various biological materials, have become increasingly prominent in addressing these issues, offering rejuvenation and revitalization. This review offers a comprehensive examination of these injectables, detailing their types, mechanisms of action, and clinical uses. It also evaluates the evidence for their effectiveness and safety in treating age-related skin alterations and other conditions. The goal is to provide an insightful understanding of injectable skin boosters in contemporary dermatological practice, summarizing the current state of knowledge.

AbstractThe first Asia-Pacific consensus recommendations for endoscopic and interventional management of hilar cholangiocarcinoma were published in 2013. Since then, new evidence on the role of endoscopy for management of malignant hilar biliary obstruction (MHBO) has emerged. To update the recommendation, we reviewed the literature using a PICO (population/intervention/comparison/outcomes) framework and created consensus statements. The expert panel voted anonymously using the modified Delphi method and all final statements were evaluated for the quality of evidence and strength of recommendation. The important points with inadequate supporting evidence were classified as key concepts. There were seven statements and five key concepts that reached consensus. The statements and key concepts dealt with multiple aspects of endoscopy-based management in MHBO starting from diagnosis, strategies and options for biliary drainage, management of recurrent biliary obstruction, management of cholecystitis after biliary stenting, and adjunctive treatment before stenting. Although the recommendations may assist physicians in planning the treatment for MHBO patients, they should not replace the decision of a multidisciplinary team in the management of individual patients.

Published: July 2024

AbstractThe introduction of cadaveric dissection of cerebral vasculature as a part of the neurosurgical training module would help the neurosurgical residents to understand the complex neuroanatomy of the brain vasculature and help gain confdence during the surgical procedure.To the best of our knowledge microsurgical anatomical studies of theMCA have not been done among the Northwest Indian population. Anatomical variations of MCA that have not been described before may come in as a surprise during any surgical intervention. Hence, we intend to record the anatomical variations of the MCA anatomy and its implications in contemporary vascular surgery and neurosurgical practice. The objective of this work was to study and compare the microsurgical anatomy and variations of MCA in Northwest Indian cadavers with the available literature.

AbstractThe objective of this review is to expose the main genetic changes and genetic polymorphisms that may or may not be associated with greater susceptibility to reduced survival of dental implants and, consequently, to their loss. Case–control studies that fully portrayed the specific types of genetic polymorphisms that may be associated with dental implant failure were included by searching in the PubMed, Scopus, and Web of Science databases from 2010 to 2023. The following descriptors and their combinations in English were used to search for articles: “dental implants,” “bone genes,” “genetics,” “polymorphism genetics,” “genetic risk factor,” and “interleukin.” The initial search resulted in 107 results (PubMed n = 47, Scopus n = 14, and Web of Science n = 46). After a manual search, reviewing each article's title and abstract, and excluding duplicates, systematic reviews, and literature reviews, 30 articles were selected. After reading these 30 articles in full, 18 studies that did not describe the specific genetic polymorphism in relation to dental implant survival were excluded. Therefore, 12 articles were included in this review. The genetic polymorphisms of interleukin (IL)-1A, IL-1B, IL-4, IL-6, IL-10, IL-1 receptor antagonist, tumor necrosis factor-α, receptor activator of nuclear factor kappa B legend, and cluster of differentiation 14 were analyzed in the included studies. In seven of the studies, a statistically significant correlation between genetic polymorphisms and dental implant failure was observed. Of the polymorphisms studied, IL-1A (−899), IL-1B (+3954), and IL-4 (+33) showed a greater association with dental implant loss.

Published: July 2024

Abstract
Introduction Brain injuries from blasts are increasingly common in both civilian and war settings. The impact of blast injuries at different pressure levels remains unclear, and their long-term effects are not well understood. This study investigates how varying blast pressures affect the rat brain over time.
Materials and Methods Forty adult Sprague-Dawley rats were randomized into four groups of 10. Three groups were exposed to blasts, while one served as a control and was only subjected to blast sounds. Each group received a single blast at different pressures, followed by neuropsychological tests. After 28 and 84 days, the rats were sacrificed to measure tau protein and acetylcholine esterase levels and to conduct histological examinations of brain tissues.
Results A single blast exposure did not significantly impact visuospatial memory or recall. Despite the lack of noticeable cognitive deficits, histopathological and biochemical analyses revealed reduced tau protein levels, indicating ongoing neuronal damage.
Conclusion While a single blast did not significantly impair visuospatial memory or recall in this rat model, there were decreases in tau protein and acetylcholine esterase levels, along with histological signs of neuronal damage.
Plasmonic magnesium arrays with nanosphere lithography
Authors: Pehlivan Zeki Semih , Ten Andrey , Wayman Thomas M. R. , Ringe Emilie 
Published: July 2024

Magnesium is a rising alternative plasmonic metal that is potentially cheaper, more biocompatible, and less lossy in the ultraviolet-blue region of the visible spectrum than the commonly used gold and silver. Recent studies of colloidal magnesium nanoparticles demonstrated the plasmonic resonances of a variety of faceted shapes. However, applications such as refractive index sensing benefit from well-defined arrays, which have been developed for all other plasmonic metals. Here, we implement nanosphere lithography to fabricate metallic magnesium arrays that display attractive plasmonic properties. The deposition process was found to be highly vulnerable to oxidation, recrystallization, kinetic energy of the metal vapor, and substrate properties. The resulting structures obtained with 350, 500, and 750 nm hexagonally packed nanosphere masks exhibit the hallmark light–matter interactions of plasmonic metals, including strong extinction and resonance energy dependence on feature size, further securing Mg’s place as an alternative plasmonic metal.
On the production of subject and object relative clauses by child speakers of heritage Romanian in
France
Authors: Avram Larisa , Mardale Alexandru , Soare Elena 
Published: July 2024

Abstract
This study investigates the production of subject and object restrictive relatives in child
heritage Romanian in contact with French. The main goal is to evaluate the effect of schooling in the societal
language, over a longer period of time, on the acquisition of these complex syntactic structures. Thirty-two child
Romanian heritage speakers (ages 5–15), divided into two groups who – at testing time – had been in a French school
for 1 to 3 years and for 5 to 8 years, respectively, completed an elicited production task. Their responses were
compared to those of 32 age-matched monolingual Romanian children and 20 Romanian adults living in the homeland. The
results indicated overall progress after onset of schooling. Child heritage speakers who had been in a French school
for a longer period of time produced more relative clauses than the younger ones and the number of errors decreased
with age. They went through the same qualitative stages as age-matched monolinguals but at a slower pace, with object
relatives being more problematic than subject relatives. This vulnerability was reflected in a preference for less
computationally costly but target-like structures and in the relatively prolonged use of non-target-like structures
whose elimination from the grammar requires inspection of a higher amount of input.
The narrative abilities of Spanish monolinguals and Spanish–Catalan bilinguals with Prader–Willi syndrome
Authors: Garcia-Alcaraz Estela , Liceras Juana M. 
Published: July 2024

Abstract
This study investigates the narrative abilities of seven Spanish monolinguals and six Spanish –
Catalan bilinguals with Prader–Willi syndrome. All participants were asked to narrate A boy, a dog, and a
frog (Mayer, 1967) in Spanish. Additionally, bilinguals were
also asked to narrate Frog, where are you? (Mayer, 1969) in
Catalan. Both narrative corpora were analyzed according to their macrostructure (Narrative Scoring
System) and microstructure (Mean Length per Utterance and Type-Token
Ratio measures). Monolinguals and bilinguals showed similar macrostructural abilities as well as
comparable morphosyntactic language development; however, a positive effect of bilingualism was detected when
evaluating participants’ lexical variability. Bilingual speakers showed comparable narrative abilities in both Spanish
and Catalan.
Code-switching and code-mixing in bilingual Spanish–Catalan children with and without Developmental
Language Disorder

Published: July 2024

Abstract
This study focuses on a specific bilingual context to study code-switching and code-mixing in
Spanish-Catalan simultaneous bilingual children with and without language difficulties with similar exposure to these
close languages. We aimed to know whether children with DLD showed different code-switching and code-mixing patterns
compared to children without language difficulties and explored the role of some variables that could affect their
use, such as the language spoken by their parents and children’s ages. Fifteen Spanish-Catalan bilingual children with
DLD and their age controls were followed from 8 to 12 years of age. Children were audio-recorded while they produced
an oral narrative task in the language chosen by the child. Results indicated that children whose parents spoke both
languages at home also use more code-mixing at 12 than parents that only spoke one language. Besides bilingual
children with DLD showed more code-switching only at an earlier age (i.e., 8) but not more code-mixing than their
age-matched peers. We discuss these results considering several explanaitions.

Published: July 2024

Abstract
Harvesting energy from ambient environments such as vibrations is a feasible approach to self-power low-powered electric devices. The dielectric elastomer generator (DEG) is a type of novel electrostatic generator with superior vibration energy harvesting (EH) performance. On the basis of traditional DEGs, a new concept of dielectric elastomer (DE)-air generator (DEAG), which contains the air layer and the DE membrane (DEM) as a composite dielectric layer, is proposed in this paper for the first time. Inspired by a classical truncated cone DEG (TC-DEG) concept, the novel truncated cone DEAG (TC-DEAG) is designed and comprehensively studied. Compared with the TC-DEG, the proposed TC-DEAG provides the larger capacitance ratio, leading to superior electrical output. The energy conversion mechanisms of both the TC-DEG and the TC-DEAG under a regular linear reciprocating excitation are analyzed theoretically by deducing the deformation condition of the DEM and the electrical outputs. Through measuring the capacitance of the DEM under deformations and testing the output voltage of the fabricated generators, the proposed theoretical models and predictions are verified. Moreover, numerical simulations based on the verified theoretical model are conducted to reveal the influences of some important system parameters on the EH performances of both generators, providing guidelines for the performance improvement of the generators.
