Hydrotherapie bei Spannungskopfschmerzen und Migräne – ein Update
Authors: Gündling Peter W. 
Published: October 2024

ZusammenfassungKopfschmerzen sind eines der häufigsten Krankheitssymptome und Beschwerden von Menschen überhaupt. Ob als Begleiterscheinung von Erkältungen und Infektionen oder als Folge von Stress, Wetterwechsel oder anderen Ursachen. Als meist funktionelle Störungen sind sie stark von der Lebensweise der Betroffenen abhängig und können daher gut mit natürlichen Maßnahmen behandelt werden. Hydrotherapie kann bei Spannungskopfschmerzen und Migräne durch die Anwendung von Wasser in verschiedenen Formen, wie warmen oder kalten Güssen, Wickeln, Bädern oder Duschen, Linderung verschaffen. Die Wärme fördert die Durchblutung und entspannt verspannte Muskulatur, während Kälte Entzündungen reduzieren und Schmerzen betäuben kann. Zudem kann die Hydrotherapie Stress abbauen und das allgemeine Wohlbefinden steigern, was ebenfalls zur Verringerung der Häufigkeit und Intensität von Kopfschmerzattacken beitragen kann.

Published: October 2024

ZusammenfassungKeimzelltumore sind die häufigsten Tumorentitäten bei jungen Männern. Seit der Einführung
der platinbasierten Chemotherapie in den 1970er-Jahren können die meisten Patienten trotz der
Aggressivität der Keimzelltumoren kurativ behandelt werden. Für Diagnostik, Therapiemonitoring
und Nachsorge werden möglichst optimale Serumtumormarker benötigt, an die hohe Anforderungen
gestellt werden. Die konventionellen Hodentumormarker humanes Choriongonadotropin (hCG),
Alpha-Fetoprotein (AFP) und Laktatdehydrogenase (LDH) werden diesen Anforderungen nur mit
einer unzureichenden Sensitivität gerecht (30–70%). Die in den letzten Jahrzehnten
untersuchten Marker wie PLAP, CEA und NSE haben sich nicht durchgesetzt. Aktuell wird
besonders die miRNA-371 erforscht. Gesicherte Erkenntnisse liegen vor für das initiale Staging
mit deutlich besseren Spezifitäten der miRNA-371 im Vergleich zu den konventionellen
Tumormarkern. Für weitere mögliche klinische Einsatzgebiete wie der Nachsorge, dem
Therapiemonitoring oder bei Residualtumoren erfolgen weitere prospektive Studien, um auch hier
das revolutionäre Potenzial der miRNA-371 zu untersuchen. Weiterhin wird aktuell an
zirkulierenden Tumorzellen (CTCs) und zellfreier DNA (cfNA) in verschiedenen
Anwendungsgebieten geforscht. In Bezug auf Keimzelltumore des Hodens stehen diese Analysen
jedoch noch am Anfang, aber man erhofft sich hiervon eine weitere suffiziente Möglichkeit
Serumtumormarker einzusetzen.

Published: October 2024

Objective The global issue of greenhouse gas emissions has significant implications for the environment and human health. Telemedicine provides a valuable tool for delivering health care while reducing gas emissions by limiting the need for patient travel. However, the environmental effects of telemedicine in high-risk pregnancy populations remain unassessed. The aim of this study was to estimate the economic and environmental impact of an outpatient teleMFM program.
Study Design This retrospective cohort study examined all visits at three teleMFM clinics more than 90 miles away from the nearest in-person MFM office between October 1, 2021, and May 1, 2022. Travel distances and times were calculated for each appointment between the patient's home, telemedicine clinic, and nearest in-person clinics, using zip code data and Google Maps web-based map calculator tools. Travel cost savings and environmental impact were calculated by determining differences in mileage reimbursement rate and emissions between those incurred in attending telemedicine appointments and those that would have been incurred if in-person using inflation-adjusted Internal Revenue Service annual standard mileage reimbursement rate ($0.58 per mile), and the U.S. Environmental Protection Agency Office of Transportation and Air Quality's average annual emissions and fuel consumption for gasoline-fueled passenger vehicles.
Results During the study period, a total number of 2,712 appointments were scheduled, of which 2,454 were kept (cancellations removed) and analyzed. Visiting a teleMFM clinic resulted in 204 miles, 200 minutes, and $118.32 saved per patient visit compared with visiting the nearest in-person clinic. Over a 7-month period, a total of 96.6 metric tons of emissions were saved.
Conclusion This study demonstrates the positive economic and environmental impact of teleMFM utilization in communities remote from in-person care. Given the contribution of greenhouse gas emissions to climate change, such findings may provide strategies for our specialty to make informed policy, advocacy, and business decisions.

Published: October 2024

Abstract
Introduction The objective of this study is to analyze the conversion rate of abstracts presented at the European Paediatric Surgeons' Association (EUPSA) congress into full-text publications and to conduct a thorough analysis of the attributes and quality of the papers published.
Materials and Methods Abstract books including the years 2017 to 2022 were reviewed. Searches on PubMed and Google Scholar, utilizing keywords from the titles and the author names, were conducted to trace subsequent full-text publications. A categorical analysis detected variations and trends, with a significance threshold of p < 0.05. Quantitative data were presented as means ± standard deviations, whereas categorical data were represented as counts (n) and percentages (%).
Results A total of 2,139 abstracts were presented at the EUPSA annual meetings during five consecutive congresses. The average number of presented abstracts was 427.6 ± 20.4 per year from across 63 different countries. European countries contributed the majority (71%). The presentations included both oral (n = 817, 38.2%) and poster presentations (n = 1,322, 61.8%). They predominantly focused on clinical topics (90.6%). Single-center retrospective studies were the most common study design (43.7%). Out of all abstracts presented, 1,033 (48.3%) were published within an average time interval of 1.39 ± 1.19 years after presentation. Most journals had an impact factor (IF) between 1 and 5 (74.5%). There was no significant year-to-year variation in publication rates (p = 1). Basic science studies were published in journals with significantly higher IF compared with clinical studies (p < 0.001).
Conclusions The publication rate of abstracts presented at the EUPSA annual congress stands at 48.3%, aligning with the rates observed in other similar studies. This suggests that abstracts submitted to the EUPSA congresses were evaluated and scored rigorously, adhering to international selection criteria. Furthermore, the majority of these abstracts were published in journals with moderate to high IFs, providing quantitative evidence of the scientific quality of research within the field of pediatric surgery.

Published: October 2024

AbstractThe aim of this study was to study the utility of pediatric flexible bronchoscopy as an interventional tool. This is a prospective study conducted in a tertiary care hospital. The studied patients underwent flexible bronchoscopy for various diagnostic and therapeutic reasons. The endpoint was to document the type of therapeutic procedure done in a patient, success rate, and any procedural complications encountered. During the 7-year period, a total of 824 different bronchoscopic procedures were conducted. The majority of procedures were for diagnostic reasons. A total of 68 therapeutic procedures were performed successfully, which included foreign body retrieval in 46 patients, bronchoscopic intubation in 5 patients, transbronchial needle aspiration (TBNA) in 4 patients, dilatation of tracheal stenosis in 4 patients, mucus plug removal in 3 patients for lung collapse, postoperative hydatid membrane removal in 3 patients, whole lung lavage in 2 patients, and transbronchial needle biopsy (TBNB) for suspected fibrosing mediastinitis in 1 patient. The 7-year audit of therapeutic role of flexible bronchoscopy (FB) in children revealed that the procedure is safe and can be utilized for many therapeutic procedures in children, including removal of aspirated foreign bodies, bronchoscopic intubation, dilatation of tracheal stenosis, treatment of atelectasis, and collection of biopsy specimens from the mediastinum. The procedure is safe and carried no major complication rate.

AbstractIncreased inflammation in premature infants in the prenatal period reduces respiratory distress syndrome (RDS). Several systemic inflammatory indices have been used to evaluate inflammatory responses in different pathologies. Our study aimed to determine the systemic inflammatory indices as predictors of lung maturation in preterm infants born before 32 weeks of gestation. In this study, preterm infants born before 32 weeks of gestation were enrolled and categorized based on the diagnosis of RDS. At birth, infants were assessed for various systemic inflammatory indices, including the systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), systemic inflammation response index (SIRI), and the monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). The study included 365 infants, of whom 211 had RDS. The median gestational ages (GA) were 27 (range: 25–29) and 30 (range: 29–31) weeks, and the median birth weights were 850 (range: 660–1,360) and 1,375 (1,090–1,600) g in the RDS and control groups, respectively. Infants in the RDS group had significantly lower MLR, NLR, PIV, SII, and SIRI values (p = 0.001) compared to the control group. The cutoff values for predicting RDS in the whole group were 239 for SII, 0.44 for SIRI, and 78 for PIV. For the group of preterm infants born at ≤28 weeks of gestation, values of 171, 0.5, and 87 for SII, SIRI and PIV, respectively, provided the best ability to predict RDS. For the whole cohort, SII level ≥239 was associated with a reduced risk of RDS, as revealed by multivariate analyses (p = 0.001). To account for GA, we performed regression analyses for infants born at ≤28 weeks. SII ≥171 (odds ratio [OR]: 0.12; 95% confidence interval [CI]: 0.05–0.3), PIV ≥87 (OR: 0.08; 95% CI: 0.03–0.21), and SIRI ≥0.5 (OR: 0.08; 95% CI: 0.03–0.2) were associated with a reduced risk of RDS. Inflammation in the perinatal period may reduce the frequency of RDS in premature infants.

The Mapping channel of the Visible and InfraRed Thermal Imaging Spectrometer (VIRTIS-M) aboard Rosetta acquired many hyperspectral images of comet 67P/Churyumov–Gerasimenko (hereafter 67P). The VIS channel detector responsivity was dependent on the VIS detector temperature (TVIS). This affects the absolute values of the measured spectra (for a TVIS increase of 1 K between 0.06% increase at 0.55 μm and 1.2% increase at 1 μm) and the spectral slopes. Here, we derive a simple parameterization of this CCD-typical effect based on a statistical analysis of the TVIS-related bias of the measurements. At this, we include all measured VIS spectra excluding acquisitions with little nucleus surface information or at opposition geometry, thereby achieving a high statistical significance and representativity. The corresponding VIS detector responsivity correction, slightly different for measurements acquired when the IR cryocooler was off or on, makes the spectra measured at different instrument temperatures consistent over the entire Rosetta mission phase at 67P. This will improve future quantitative analyses of the data.

Published: October 2024

Abstract
The transmission electron microscope (TEM) is a powerful imaging, diffraction and spectroscopy tool that has revolutionized the field of microscopy. It has contributed to numerous breakthroughs in various scientific disciplines. TEM-based techniques can offer atomic resolution as well as elemental analysis, which benefit the study of epitaxial semiconductors and their related optoelectronic devices on the atomic scale. The design and optimization of the device performance depend on three key factors: the control of strain at nanometer scale, control of the formation and propagation of defects as well as the control of local electronic properties. Manipulation and optimization are only possible if the key factors can be characterized precisely. Herein, the TEM techniques for strain analysis, defect characterization and bandgap evaluation are reviewed and discussed. Lately, with the development of in-situ TEM techniques, researchers have been able to observe dynamic processes and study the behaviour of materials and devices under realistic conditions (in gaseous atmosphere or in liquids, at elevated or cryogenic temperatures, under strain, bias or illumination) in real-time with extremely high spatial resolution. This review explores the impact and significance of in-situ TEM in the field of semiconductors.
Effect of charge state on alkaline OER activity in FeN4–Gr catalyst supported on Ni (111) substrate

Published: October 2024

Abstract
The catalysts of transition metal single–atom embedded in N–doped graphene (TMN4–Gr) have attracted significant attention due to the high utilization of transition metal atoms, remarkable selectivity and tunable catalytic activity. In this study, we have employed first–principles study to investigate alkaline oxygen evolution reaction (OER) activity of FeN4–Gr system supported on a Ni (111) substrate (FeN4–Gr/Ni). The results show that the Ni substrate can significantly enhance the OER activity of FeN4–Gr catalyst. The overpotential of FeN4–Gr/Ni catalyst is 0.63 V, much lower than 0.79 V of the FeN4–Gr, which is closely related to the strong interaction from the Ni substrate. By subtracting electrons from the FeN4–Gr/Ni catalyst, a positive charge environment can be created. It is found that, between the FeN4–Gr and the Ni substrate, a significant electron transfer phenomenon is observed, and the amount can be regulated by the charge state. Besides, the charge state can obviously tune the adsorption strength of *OOH intermediate through the interaction of Ni substrate, further optimizing the OER activity thermodynamically favorable. As the charge state increases to +1.55, the overpotential decreases to 0.23 V. By analyzing the integrated crystal orbital Hamilton populations, the chemical bond strength of Fe–O is discussed. Our results reveal that the Ni substrate can significantly enhance the OER activity of the FeN4–Gr catalyst, and the charge state can also tune the overpotential, offering valuable insights for the design of high–efficiency single–atom catalysts utilizing metal substrate.

Published: October 2024

Abstract
Designing and manufacturing multi-component alloy samples with ultralow magnetic susceptibility χ (<10−6 cm3 mol−1) is crucial for producing high-quality test masses to successfully detect gravitational wave in the LISA and TianQin projects. Previous research has idenfified AuPt alloys as a potential candidate for test masses, capable of achieving ultralow magnetic susceptibility that meets the requirements from both theoretical and experimental perspectives. In this study, we discover that the structural strain regulation (i.e. tensile and stress) can effectively optimize and further reduce the ultralow magnetic susceptibility of AuPt allpys, while fully understanding their underlying physical mechanisms. More importantly, even when doped with trace elements such as Fe or Bi impurity, strain regulation can still effectively reduce the magnetic susceptibility of the doped AuPt alloy to the desired range. Our theoretical calculations also reveal that, when the strain ratio η is controlled within in a relatively small range (<2.0%), the regulaton effect on the ultralow magnetic susceptibilities of pure or doped-AuPt alloys remains significant. This property is beneficial for achieving ultralow or even near-zero magnetic susceptibility in real AuPt alloy samples.

Published: October 2024

Abstract
Low-dose radiographic inspection is a growing trend in industry to minimize radiation risks to humans and the environment. However, reduction in radiation dose often introduces significant noise, which affects image quality and hinders accurate identification of subtle defects. This study addresses this issue by introducing a novel phenomenon called aperiodic reverse stochastic resonance (ARSR), observed in nonlinear systems excited by aperiodic binary signals. ARSR enables simultaneous amplitude amplification and reversal of signals under specific noise conditions. Leveraging ARSR, we propose an image denoising framework for low-dose radiographic inspections. First, a set of projection data is obtained by using Radon transform to reduce the dimensionality of x-ray images from different angles. Then, the projection data is modulated based on the ARSR system. Finally, the image is reconstructed based on the inverse Radon transform. Simulations and experimental comparison results in welding applications validate the effectiveness of the framework, demonstrating significant improvements in image quality for low-dose radiographic defect detection. Unlike advanced methods such as Gaussian filtering, BM3D, and DnCNN, which operate at the pixel level, ARSR performs denoising at the projection data stage, reducing noise impact, preserving original information, and focusing on physical data processing during imaging. This approach enhances the detection of subtle defects, highlighting the potential of stochastic resonance in image processing.
Incipient fault detection for the spindle bearing of a cement grinding machine based on vibrational resonance
Authors: Xiao Lei , Zhao Hailong , Gao Shaofeng , Zhou Qihong 
Published: October 2024

Abstract
The spindle bearing of a circulation fan is an important component of a cement grinding machine. In addition to the faults on the spindle bearing, impeller wear and ash accumulation may cause dynamic unbalance and complex vibration interference as noise, which decreases the accuracy of fault detection based on vibrational signals and traditional signal processing-based methods at the early stage of a bearing fault. To address this issue, this paper presents a new fault detection method for the spindle bearing by utilizing extra injected noise and vibrational resonance. To enhance the fault signature and resonance performance, the nonlinear system of the traditional vibrational resonance is replaced by a new hybrid steady-state system, and the underdamped term is considered in the new system. The proposed system provides more possibilities to achieve resonance by adjusting the system parameters and overcomes the limitations of output saturation caused by the classical bistable system. The proposed method is validated by analyzing the collected vibration signals from a spindle bearing of a circulation fan in practice and is compared with other noise-elimination fault detection methods. The results demonstrate the effectiveness and superior performance of the proposed method.
Ion motion in strongly magnetized cluster laser plasma

Published: October 2024

Abstract
This paper investigates the interaction of high intensity, circularly polarized, short laser pulses with heavy cluster plasma through analytical modeling and numerical simulations. The optimal parameters were found for the generation of several GigaGs quasi-stationary magnetic field by using the upgraded analytical model and detailed 3D PIC simulations. It is confirmed that a field of such strength slows down the thermal expansion of the cluster core in the direction transverse to the laser beam axis, which can be used in nuclear physics. The generated inward shocks produce ion core compression, which is relevant to nuclear fusion. The electrostatic interaction between the rotating laser field, electrons and ions leads to an ion spiral density distribution in the cluster’s transversal plane, which is absent in a cluster irradiated by linearly polarized pulses with the same parameters.
