Zusammenfassung
Hintergrund Chronischer Schmerz ist nach Unfällen und Operationen
eine Langzeitkomplikation, deren Relevanz für Patienten im BG-lichen
Heilverfahren in Deutschland kaum untersucht ist.
Fragestellung Erste Statuserhebung der Häufigkeit chronischer
Schmerzen nach Arbeitsunfall.
Methoden In 2017 wurden chirurgisch-stationäre BG-Patienten
(18–65 J.) eines Tertiärkrankenhauses zu chronischen
Schmerzen, die seit einem BG-lich anerkannten Trauma bestanden (Intervall
2,8±6,9 Jahre), ungeachtet einer stattgehabten Versorgung, erstmalig zum
Zeitpunkt eines Krankenhausaufenthalts und dann telefonisch 6 Monate
später befragt. Der Fokus lag auf Patienten mit einem Arbeitsunfall (A)
innerhalb des letzten Monats oder (B) >6 Monaten. Primäres
Outcome: Häufigkeit arbeitsunfallbedingter chronischer Schmerzen
(>6 Monate) zum Initialinterview (Punktprävalenz),
sekundäre Outcomes: Häufigkeit einer Chronifizierung nach 6
Monaten (A) und Persistenz chronischer Schmerzen (B). Tertiäre Outcomes:
Arbeitsfähigkeit, Verletzungsartenverfahren, Auswirkungen anhand
Schmerzintensität, -lokalisation und -medikation,
Funktionseinschränkung in Abhängigkeit der Existenz chronischer
Schmerzen sowie Komorbidität.
Ergebnisse 415 Patienten wurden eingeschlossen, 85%
(160/188) berichteten von unfallabhängigen chronischen Schmerzen
(überwiegend mittlere bis sehr starke Intensität, an Gelenken
und Knochen lokalisiert). 90% (131/145) gaben diese Schmerzen
auch sechs Monate später an. 67% (64/96) gaben erstmalig
chronische Schmerzen an. Patienten mit chronischen Schmerzen zum Follow-up
(281/369) nahmen seltener ihre Berufstätigkeit wieder auf
(p=0,003), in 60% Analgetika ein, waren öfter komorbide
(p<0,002) und stärker in ihrer
Extremitätenfunktionalität beeinträchtigt
(p<0,002).
Schlussfolgerung Auch wenn die Ergebnisse als vorläufig zu
bewerten sind, scheinen chronische Schmerzen nach Arbeitsunfall sehr
häufig und beeinflussen die Wiederherstellung der
Arbeitsfähigkeit langfristig negativ. Anhand der vorliegenden
anamnestischen Zahlen ist eine weiterführende differenzierte
Reevaluation prospektiver Daten unter Beachtung therapeutischer
Maßnahmen dringend anzuraten.

ZusammenfassungDer Fallbericht beschreibt die interdisziplinäre Behandlung einer
komplexen Granatsplitterverletzung des rechten Femurs bei einem
18-jährigen ukrainischen Soldaten. Die offene mehrfragmentäre
Defektfraktur des Femurs mit Substanzdefekt und Osteomyelitis wurde durch
mehrere multiresistenten Bakterien, u. a. Acinetobacter baumanii,
verkompliziert, welche durch eine mehrfache Antibiotikatherapie nicht eradiziert
werden konnte. Keimfreiheit konnte erst durch mehrfaches radikales Debridement
und lokale Spül-Vakuum-Therapie mit hypochloriger Säure erreicht
werden. Anschließend wurde das Femur mit einem chimären
Double-Barrel-Fibula-Lappenplastik rekonstruiert. Dieser Bericht unterstreicht
die Bedeutung multimodaler antimikrobieller Wundbehandlungen in Zeiten
zunehmender Antibiotikaresistenzen, um die plastisch-rekonstruktive Therapie zu
ermöglichen.
Dilemma of Epigenetic Changes Causing or Reducing Metabolic Disorders
in Offsprings of Obese Mothers
Authors: Sharma Shikha , Bhonde Ramesh 
Published: October 2023

AbstractMaternal obesity is associated with fetal complications predisposing later to the
development of metabolic syndrome during childhood and adult stages. High-fat
diet seems to influence individuals and their subsequent generations in
mediating weight gain, insulin resistance, obesity, high cholesterol, diabetes,
and cardiovascular disorder. Research evidence strongly suggests that epigenetic
alteration is the major contributor to the development of metabolic syndrome
through DNA methylation, histone modifications, and microRNA expression. In this
review, we have discussed the outcome of recent studies on the adverse and
beneficial effects of nutrients and vitamins through epigenetics during
pregnancy. We have further discussed about the miRNAs altered during maternal
obesity. Identification of new epigenetic modifiers such as mesenchymal stem
cells condition media (MSCs-CM)/exosomes for accelerating the reversal
of epigenetic abnormalities for the development of new treatments is yet another
aspect of the present review.

Published: October 2023

Zusammenfassung
Zielsetzung Von der COVID-19-Pandemie waren junge Menschen stark
betroffen, was zu erhöhter psychischer Belastung und steigenden
Prävalenzraten für psychische Störungen geführt
hat. Es besteht die Sorge, dass neben einem beobachteten Anstieg der
Suizidversuche auch die Suizide zugenommen haben.
Methode Die Studie basiert auf der Polizeilichen Kriminalstatistik
(01/2017 bis 12/2022) von drei
Flächenbundesländern in Deutschland, die 13 % der
Gesamtbevölkerung Deutschlands repräsentieren. Die Suizidzahlen
und -raten für die Altersgruppen der Kinder, Jugendlichen,
Heranwachsenden und jungen Erwachsenen wurden mit Hilfe von Chi-Quadrat-Tests
zwischen dem präpandemischen und dem pandemischen Zeitraum
verglichen.
Ergebnisse 860 Personen unter 30 Jahren starben durch Suizid. Die
Suizidraten unterschieden sich in keiner der untersuchten Altersgruppen zwischen
dem präpandemischen und dem pandemischen Zeitraum.
Schlussfolgerung Bislang ist kein Anstieg der Suizide unter jungen
Deutschen zu erkennen. Ein kontinuierliches Suizidmonitoring wird empfohlen.
Skeletal Rearrangements Involving Cyclopropyl- and Alkene-Stabilized Silylium Ions

Published: October 2023

AbstractThis Account summarizes the fascinating chemistry of cyclopropyl-stabilized silylium ions, which are readily available from vinylcyclopropanes (VCPs). Depending on the nucleophilic partner, these reactive intermediates undergo direct ring opening or ring expansion to nonclassical alkene-stabilized silylium ions. The latter can also be accessed by gold as well as proton electrophiles from silicon compounds containing unsaturated C–C bonds. All these reaction cascades can be terminated by C–H or C–C as well as Si–O bond formation. From this, a clearer picture of the versatility of these rather complex chemistries emerges.1	Introduction2	Skeletal Rearrangements of Vinylcyclopropanes Involving Cyclopropyl-Stabilized Silylium Ions2.1	Termination by C–H Bond Formation2.2	Termination by C–C Bond Formation3	Related Bond Reorganizations Involving Alkene-Stabilized Silylium Ions3.1	Initiation by Cationic Gold(I) Complexes3.2	Initiation by Brønsted Acids4	Conclusion
Hyperventilation and Seizures: Not a New Sense: A Literature Review
Authors: Rana Mandeep , Steenari Maija , Shrey Daniel 
Published: October 2023

AbstractHyperventilation and seizures have a long association in the clinical literature and were known to have a relationship long before the electroencephalogram (EEG) was used to record changes in brain activity. As the use of EEG recording progressed, hyperventilation was the first activation method used to assist with diagnosis of epilepsy. Along with slowing of brain activity, hyperventilation can activate epileptiform spiking activity in patients with epilepsy. Currently, hyperventilation is used in standard practice to assist with the diagnosis of epilepsy during EEG recording. Hyperventilation activates epileptiform spiking activity more often than seizures but can trigger clinical seizures in up to 50% of patients with generalized epilepsy. It is more likely to trigger events in children with absence seizures than adults, and it acts as a trigger in patients with focal epilepsy far less often. However, while some clinicians suggest that its diagnostic value is limited, especially in adults with focal epilepsies, others suggest that it is simple, safe, and an important diagnostic tool, even in these patients. This review presents the history of hyperventilation and seizures, its use in the clinical practice, and possible mechanisms involved.
A versatile 4 K insert for characterization of the superconducting joints
Authors: Nandawadekar Ajit , Singh Mukhtiar , Kar Soumen 
Published: October 2023

A multi-coil superconducting magnet is the heart of any modern Magnetic Resonance Imaging (MRI) scanner. The superconducting magnet in MRI produces a highly homogeneous field (±5 ppm) and stable field (&lt;0.1 ppm/h) in its imaging volume. The temporal field stability depends on the electrical resistance of the inter-coil joints and the electrical resistance of the joint between the coil and the superconducting switch. To establish the joint technology, a 4 K test rig is required for testing the sample joints. This paper briefly discusses the details of the versatile 4 K insert recently developed at IUAC for the characterization of the superconducting joints using the field-decay measurement technique. It can measure the joint resistance up to ∼10−15 Ω in a straight or spiral joint configuration with lengths up to 150 mm. The maximum current that can be induced on the test coil is more than 600 A for the field-decay measurement. The behavior of the joint resistance can also be studied in the presence of a 1.5 T background field. We have characterized many superconducting joints using this versatile 4 K insert. The joints between two different conductors can also be studied using this 4 K insert. The lowest joint resistance measured is 8 × 10−15 Ω at zero field. The joint resistance is also measured in the presence of the background field.

Laser-induced surface structuring is a promising method to suppress electron mulitpacting in the vacuum pipes of particle accelerators. Electrons are scattered inside the rough surface structure, resulting in a low Secondary Electron Yield (SEY) of the material. However, laser processing of internal pipe surfaces with a large aspect ratio is technologically challenging in terms of laser beam guidance and focusing. We present a 532 nm ultrashort-pulse laser setup to process the inner parts of 15 m long beam vacuum tubes of the Large Hadron Collider (LHC). Picosecond pulses at a repetition rate of 200 kHz are guided through an optical fiber toward an inchworm robot traveling inside the beam pipe. The system was installed, characterized, and tested for reliability. First surface treatments achieved the required scan precision. Cu2O-dominated nano-features were observed when processing at high average laser power (5 W) and slow scanning speed (5 mm s−1) in nitrogen flow, and the maximum SEY of copper was decreased from 2.1 to 0.7.
Thermal transport across TiO2–H2O interface involving water dissociation: Ab initio-assisted deep potential molecular dynamics
Authors: Li Zhiqiang , Wang Jian , Yang Chao , Liu Linhua , Yang Jia-Yue 
Published: October 2023

Water dissociation on TiO2 surfaces has been known for decades and holds great potential in various applications, many of which require a proper understanding of thermal transport across the TiO2–H2O interface. Molecular dynamics (MD) simulations play an important role in characterizing complex systems’ interfacial thermal transport properties. Nevertheless, due to the imprecision of empirical force field potentials, the interfacial thermal transport mechanism involving water dissociation remains to be determined. To cope with this, a deep potential (DP) model is formulated through the utilization of ab initio datasets. This model successfully simulates interfacial thermal transport accompanied by water dissociation on the TiO2 surfaces. The trained DP achieves a total energy accuracy of ∼238.8 meV and a force accuracy of ∼197.05 meV/Å. The DPMD simulations show that water dissociation induces the formation of hydrogen bonding networks and molecular bridges. Structural modifications further affect interfacial thermal transport. The interfacial thermal conductance estimated by DP is ∼8.54 × 109 W/m2 K, smaller than ∼13.17 × 109 W/m2 K by empirical potentials. The vibrational density of states (VDOS) quantifies the differences between the DP model and empirical potentials. Notably, the VDOS disparity between the adsorbed hydrogen atoms and normal hydrogen atoms demonstrates the influence of water dissociation on heat transfer processes. This work aims to understand the effect of water dissociation on thermal transport at the TiO2–H2O interface. The findings will provide valuable guidance for the thermal management of photocatalytic devices.
Molecular dynamics-driven global potential energy surfaces: Application to the AlF dimer
Authors: Liu Xiangyue , Wang Weiqi , Pérez-Ríos Jesús 
Published: October 2023

In this work, we present a full-dimensional potential energy surface for AlF–AlF. We apply a general machine learning approach for full-dimensional potential energy surfaces, employing an active learning scheme trained on ab initio points, whose size grows based on the accuracy required. The training points are selected based on molecular dynamics simulations, choosing the most suitable configurations for different collision energy and mapping the most relevant part of the potential energy landscape of the system. The present approach does not require long-range information and is entirely general. As a result, it is possible to provide the full-dimensional AlF–AlF potential energy surface, requiring ≲0.01% of the configurations to be calculated ab initio. Furthermore, we analyze the general properties of the AlF–AlF system, finding critical differences with other reported results on CaF or bi-alkali dimers.
Leaf manganese and phenolics as proxies of soil acidification and phosphorus acquisition mechanisms in lentil cultivars on alkaline soil
Authors: Theologidou Georgia S. , Ipsilantis Ioannis , Tsialtas Ioannis T. 
Published: October 2023

Leaf manganese (Mn) concentration has been used as a proxy for root exudation and phosphorus (P) uptake under controlled conditions, but there are limited field studies that confirm its validity. On an alkaline, P-poor soil, four lentil cultivars (‘Samos’, ‘Thessaly’, ‘Flip’, ‘Algeria’) received two P rates (0 and 26.2 kg P ha−1), for two growing seasons, to study whether aboveground assessments [leaf P, Mn, phenolic concentration (TPhe)] can approximate rhizosphere physiological traits related to P acquisition [soil acidification (ΔpH), arbuscular mycorrhizal fungi (AMF) colonisation, acid phosphatase activity (APase)]. Phosphorus addition had no effect on the determined traits. Cultivars differed in leaf P, Mn, TPhe and AMF, but there was no clear pattern relating aboveground traits to rhizosphere traits related to P acquisition, thus not confirming that leaf Mn can be a proxy of root exudation. Of three growth stages [V 7–8, R1 (first bloom), R4 (flat pod)], R1 seemed to be critical, showing the highest leaf P, ΔpH, AMF and TPhe. Precipitation and temperatures over the growing season were determinants of lentil responses affecting rhizosphere activity, soil P availability and finally leaf traits. In conclusion, in lentil on alkaline and P-limiting soils, high leaf Mn and phenolic concentration are not reliable indicators of rhizosphere P-acquiring mechanisms.

Mid-infrared thermal radiation resonating with longitudinal-optical like phonon from n++-doped GaN–semi-insulating GaN grating structure

Published: October 2023

Abstract
The mid-infrared emission mechanism of line-and-space structures of metallic plates on dielectric materials is substantiated using high conductive n-doped (n++-) GaN–semi-insulating (SI-) GaN microstripe structures on an SI-GaN epitaxial layer, which was veiled when using line-and-space structures of Au plates. The present structure exhibits a few thermal emission lines originating from electric dipoles resonating with the coherent longitudinal optical (LO) phonon-like lattice vibration, which are formed by the local depolarization electric field in the surface n++-GaN/SI-GaN/n++-GaN regions. The energies of the LO-phonon-like modes shift from the original LO-phonon energy of GaN to the lower energy region, which contrasts with the LO-phonon resonant emission from the microstructures on GaAs. These emission lines have another notable feature, i.e. the observed peak energies are independent of the polar emission angle for both s- and p-polarizations, unlike the emissions by surface phonon polaritons showing a significant directive nature of peak energies. The results show that each peak energy of the present emission lines is positioned at the zero-point of the real part of the electric permittivity comprising the components of the transverse optical phonon and other electric dipoles induced by the LO-like modes, excluding the target mode. The significant peak-energy shift of the LO-like phonons is applicable to materials with wide Reststrahlen bands, which contrasts with that of the nearly LO-phonon resonating feature of materials with narrow Reststrahlen bands, such as GaAs. The peak energy shift depending on the emission direction is observed for Au–GaN stripe structures. This property is ascribed to the imperfect Au/GaN interface with surface states through the theoretical analysis of the modified electric permittivity in the surface region, numerical simulation of the local electric field via finite-difference time-domain calculation, and experimental studies on a Ti–GaN structure and emission peaks originating from an LO-like phonon of the α-Al2O3 substrate.

Abstract
We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipole moment at the Paul Scherrer Institute. This interaction, which could be mediated by axion-like particles, concerned the unpolarized nucleons (protons and neutrons) near the material surfaces of the apparatus and polarized ultracold neutrons stored in vacuum. The dominant systematic uncertainty resulting from magnetic-field gradients was controlled to an unprecedented level of approximately 4 pT cm−1 using an array of optically-pumped cesium vapor magnetometers and magnetic-field maps independently recorded using a dedicated measurement device. No signature of a theoretically predicted new interaction was found, and we set a new limit on the product of the scalar and the pseudoscalar couplings

Dynamical quantum phase transitions following double quenches: persistence of the initial state vs dynamical phases
Authors: Cheraghi Hadi , Sedlmayr Nicholas 
Published: October 2023

Abstract
Dynamical quantum phase transitions (DQPTs) can occur following quenches in quantum systems when the rate function, a dynamical analogue of the free energy, becomes non-analytic at critical times. Here we exhaustively investigate in an exemplary model how the dynamically evolving state responds to a second quench. We demonstrate that for quenches where the initial and final Hamiltonian belong to different phases always result in DQPTs, irrespective of the intermediate quench and dynamics or the time of the second quench. However, if the initial and final Hamiltonian belong to the same equilibrium phase then the intermediate Hamiltonian must belong to a different phase. In this case, the second quench time in relation to the critical times of the first quench becomes crucial to the existence of DQPTs.
