Published: November 2022

AbstractPotassium‐ and sodium‐ion batteries (PIBs and SIBs) have great potential as the next‐generation energy application owing to the natural abundance of K and Na. Antimony (Sb) is a suitable alloying‐type anode for PIBs and SIBs due to its high theoretical capacity and proper operation voltage; yet, the severe volume variation remains a challenge. Herein, a preparation of N‐doped carbon‐wrapped Sb nanoparticles (L‐Sb/NC) using pulsed laser ablation and polydopamine coating techniques, is reported. As the anode for PIB and SIB, the L‐Sb/NC delivers superior rate capabilities and excellent cycle stabilities (442.2 and 390.5 mA h g−1 after 250 cycles with the capacity decay of 0.037% and 0.038% per cycle) at the current densities of 0.5 and 1.0 A g−1, respectively. Operando X‐ray diffraction reveals the facilitated and stable potassiation and sodiation mechanisms of L‐Sb/NC enabled by its optimal core–shell structure. Furthermore, the SIB full cell fabricated with L‐Sb/NC and Na3V2(PO4)2F3 shows outstanding electrochemical performances, demonstrating its practical energy storage application.

Published: November 2022

AbstractObjectivesResection of the middle turbinate (MT) during endoscopic sinus surgery (ESS) has been a controversial topic among otolaryngologists for many years. Some studies advocate resection and have shown improved outcomes postoperatively, while studies favoring preservation show a decreased incidence of postoperative complications. The current practice pattern regarding this subject is unknown. The goal of this study was to learn the current practice of MT resection during ESS among otolaryngologists.MethodWe performed an electronic anonymous survey of practicing otolaryngologists.ResultsWe found that the majority of the 252 responders stated that they will perform an MT resection in certain clinical situations, while there is a small subset that advocates never resecting the MT for inflammatory sinus disease (n = 6, 2.4%). Participants were significantly more likely to perform MT resection in patients undergoing revision compared to primary ESS for all conditions included. The complication of greatest concern among participants was iatrogenic frontal sinus obstruction, while empty nose was of the least concern. The majority of participants responded that MT resection was of extreme or moderate benefit for improved visualization and drug delivery postoperatively. When compared to general otolaryngologists, fellowship‐trained rhinologists were less concerned about potential complications following MT resection and were more likely to perceive an extreme or moderate benefit from turbinate resection postoperatively.ConclusionThere remains debate over MT resection among otolaryngologists, but the results of this study show that the majority of participating otolaryngologists will perform a resection in certain clinical situations.
Internal resonance and bending analysis of thick visco-hyper-elastic arches

Published: November 2022

AbstractIn this study, a comprehensive analysis of visco-hyper-elastic thick soft arches under an external time-independent as well as time-dependent loads is presented from bending and internal resonance phenomenon perspectives. Axial, transverse and rotation motions are considered for modelling the thick and soft arch in the framework of the Mooney–Rivlin and Kelvin–Voigt visco-hyper-elastic schemes and third-order shear deformable models. The arch is assumed to be incompressible and is modelled using von Kármán geometric nonlinearity in the strain–displacement relationship. Using a virtual work method, the bending equations are derived. For the vibration analysis, three, coupled, highly nonlinear equations of motions are obtained using force-moment balance method. The Newton–Raphson method together with the dynamic equilibrium technique is used for the bending and vibration analyses. A detailed study on the influence of having visco-hyper-elasticity and arch curvature in the frequency response of the system is given in detail, and the bending deformation due to the applied static load is presented. The influence of having thick, soft arches with different slenderness ratios is shown, and the forced vibration response is discussed. Moreover, internal resonance in the system is studied showing that the curvature term in the structure can lead to three-to-one internal resonances, showing a rich nonlinear frequency response. The results of this study are a step forward in studying the visco-hyper-elastic behaviour of biological structures and soft tissues.Graphic abstract
Postpartum pelvic floor muscle training, levator ani avulsion and levator hiatus area: a randomized trial
Authors: Hilde Gunvor , Stær-Jensen Jette , Siafarikas Franziska , Engh Marie Ellström , Bø Kari 
Published: November 2022

Abstract
Introduction and hypothesis
Vaginal delivery may lead to tearing of the levator ani (LA) muscle from its bony insertions (complete LA avulsion) and increased levator hiatus (LH) area, both risk factors for pelvic floor dysfunctions. Early active rehabilitation is standard treatment after musculo-skeletal injury. We hypothesized that pelvic floor muscle training (PFMT) early postpartum would reduce the presence of LA avulsions and reduce LH area.

Methods
We carried out a planned secondary analysis from a randomized controlled study. Primiparous women (n=175) giving birth vaginally were included 6 weeks postpartum, stratified on complete LA avulsion, and thereafter randomized to PFMT or control. The training participants (n=87) attended a supervised PFMT class once a week and performed home-based PFMT daily for 16 weeks. The control participants (n=88) received no intervention. Presence of complete LA avulsion, LH area at rest, maximal contraction, and maximal Valsalva maneuver were assessed by transperineal ultrasound. Between-group comparisons were analyzed by analysis of covariance for continuous data, and relative risk (RR) for categorical data.

Results
Six months postpartum, the number of women who had complete LA avulsion was reduced from 27 to 14 within the PFMT group (44% reduction) and from 28 to 17 within the control group (39% reduction). The between-group difference was not significant, RR 0.85 (95% CI 0.53 to 1.37). Further, no significant between-group differences were found for LH area at rest, during contraction, or Valsalva.

Conclusions
Supervised PFMT class combined with home exercise early postpartum did not reduce the presence of complete LA avulsion or LH area more than natural remission.
Shock ignition of aluminium particle clouds in the low-temperature regime
Authors: Omang M. , Hauge K. O.

AbstractIn this paper, we present results from spontaneous ignition of aluminium particle clouds in a series of shock tube experiments. For all experiments, the shock propagates along a narrow pile of 40-$$\upmu $$
μ
m aluminium particles. The study includes shock Mach numbers in the range from 1.51 to 2.38. The results are visualised using photographic techniques and pressure gauges. The combination of two Phantom high-speed video cameras and a beamsplitter allows a compact schlieren setup mounted together with a dark-film high-speed camera. While the schlieren technique allows the shock features to be identified, the dark-film camera is used to capture the ignition and burning of the aluminium particle clouds. Based on extensive image processing and shock tube relations for reflected shocks, spontaneous ignition of the aluminium particle cloud is found to take place for reflected shock gas temperatures above 635 K. For increasing Mach numbers, we find a decreasing trend for the ignition delay. Additionally, the burning time is observed to decrease with increasing Mach number, indicating that the burning process is more efficient with increasing gas temperature.
Characterizations and Directed Path-Width of Sequence Digraphs
Authors: Gurski Frank , Rehs Carolin , Rethmann Jochen 
Published: November 2022

AbstractComputing the directed path-width of a directed graph is an NP-hard problem. Even for digraphs of maximum semi-degree 3 the problem remains hard. We propose a decomposition of an input digraph G = (V,A) by a number k of sequences with entries from V, such that (u,v) ∈ A if and only if in one of the sequences there is an occurrence of u appearing before an occurrence of v. We present several graph theoretical properties of these digraphs. Among these we give forbidden subdigraphs of digraphs which can be defined by k = 1 sequence, which is a subclass of semicomplete digraphs. Given the decomposition of digraph G, we show an algorithm which computes the directed path-width of G in time $\mathcal {O}(k\cdot (1+N)^{k})$

, where N denotes the maximum sequence length. This leads to an XP-algorithm w.r.t. k for the directed path-width problem. Our result improves the algorithms of Kitsunai et al. for digraphs of large directed path-width which can be decomposed by a small number of sequences and confirm their conjecture that semicompleteness is a useful restriction when considering digraphs.

Abstract

Purpose
Endovascular treatment of unruptured intracranial aneurysms (UIAs) requires a risk–benefit analysis and adherence to diagnostic reference levels (DRLs). The national DRL (250 Gy·cm2) is only determined for intracranial aneurysm coiling in general, including ruptured intracranial aneurysms (RIAs). This study aims to investigate the dose in the treatment of UIAs and RIAs separately.

Methods
In a retrospective study design, dose area product (DAP) and fluoroscopy time (FT) were assessed for all patients undergoing intracranial aneurysm coiling between 2010 and 2021. DRL was set as the 75th percentile of the dose distribution. A multivariable linear regression analysis was performed to investigate DAP and FT for the two groups, UIA and RIA adjusted for patient age, aneurysm size, and location.

Results
583 (414 females, mean age 56.5 years, 311 UIAs) are included. In the overall population, DAP (median (IQR)) is 157 Gy·cm2 (108–217) with a median FT of 32.7 min (IQR 24.0–47.0). Local DRL is 183 Gy·cm2 for UIAs and 246 Gy·cm2 for RIAs. After adjustment for the other variables, the UIA and RIA groups have a significant effect on both DAP (p < 0.001; 95% CI − 68.432 – − 38.040) and FT (p < 0.001; 95% CI − 628.279 – − 291.254). In general, both DAP and FT increase significantly with patient age and aneurysm size, whereas the location of the aneurysm did not significantly change neither DAP (p = 0.171; 95% CI − 5.537–31.065) nor FT (p = 0.136; 95% CI − 357.391–48.508).

Conclusion
Both aneurysm size and patient age were associated with increased DAP, whereas aneurysm location did not significantly change DAP or FT. The increased dose in patients with RIAs is likely equivalent to additional diagnostic cerebral four-vessel angiography performed in this group.
Price of anarchy for parallel link networks with generalized mean objective
Authors: Kleer Pieter 
Published: November 2022

AbstractThe price of anarchy is the most well-known measure for quantifying the inefficiency of equilibrium flows in traffic networks and routing games. In this work, we give unifying price of anarchy bounds for atomic and non-atomic parallel link routing games with polynomial cost functions under various cost objectives including the arithmetic mean, geometric mean and worst-case cost objective. We do this through the study of the generalized p-mean as cost objective, and obtain upper bounds on the price of anarchy in terms of this parameter p. Our bounds unify existing results from the literature, and, in particular, give alternative proofs for price of anarchy results in parallel link routing games with polynomial cost functions under the geometric mean objective obtained by Vinci et al. (ACM Trans Econ Comput 10(2):41, 2022). We recover those simply as a limiting case. To the best of our knowledge, these are the first price of anarchy bounds that capture multiple cost objectives simultaneously in a closed-form expression.

Abstract
Objectives
To assess the accuracy, repeatability, and reproducibility of T1 and T2 relaxation time measurements by three-dimensional magnetic resonance fingerprinting (3D MRF) using various dictionary resolutions.

Methods
The ISMRM/NIST phantom was scanned daily for 10 days in two 3 T MR scanners using a 3D MRF sequence reconstructed using four dictionaries with varying step sizes and one dictionary with wider ranges. Thirty-nine healthy volunteers were enrolled: 20 subjects underwent whole-brain MRF scans in both scanners and the rest in one scanner. ROI/VOI analyses were performed on phantom and brain MRF maps. Accuracy, repeatability, and reproducibility metrics were calculated.

Results
In the phantom study, all dictionaries showed high T1 linearity to the reference values (R2 > 0.99), repeatability (CV < 3%), and reproducibility (CV < 3%) with lower linearity (R2 > 0.98), repeatability (CV < 6%), and reproducibility (CV ≤ 4%) for T2 measurement. The volunteer study demonstrated high T1 reproducibility of within-subject CV (wCV) < 4% by all dictionaries with the same ranges, both in the brain parenchyma and CSF. Yet, reproducibility was moderate for T2 measurement (wCV < 8%). In CSF measurement, dictionaries with a smaller range showed a seemingly better reproducibility (T1, wCV 3%; T2, wCV 8%) than the much wider range dictionary (T1, wCV 5%; T2, wCV 13%). Truncated CSF relaxometry values were evident in smaller range dictionaries.

Conclusions
The accuracy, repeatability, and reproducibility of 3D MRF across various dictionary resolutions were high for T1 and moderate for T2 measurements. A lower-resolution dictionary with a well-defined range may be adequate, thus significantly reducing the computational load.

Key Points
• A lower-resolution dictionary with a well-defined range may be sufficient for 3D MRF reconstruction.
• CSF relaxation times might be underestimated due to truncation by the upper dictionary range.
• Dictionary with a higher upper range might be advisable, especially for CSF evaluation and elderly subjects whose perivascular spaces are more prominent.

Published: November 2022

Abstract
Objectives
Evaluation and follow-up of idiopathic pulmonary fibrosis (IPF) mainly rely on high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs). The elastic registration technique can quantitatively assess lung shrinkage. We aimed to investigate the correlation between lung shrinkage and morphological and functional deterioration in IPF.

Methods
Patients with IPF who underwent at least two HRCT scans and PFTs were retrospectively included. Elastic registration was performed on the baseline and follow-up HRCTs to obtain deformation maps of the whole lung. Jacobian determinants were calculated from the deformation fields and after logarithm transformation, log_jac values were represented on color maps to describe morphological deterioration, and to assess the correlation between log_jac values and PFTs.

Results
A total of 69 patients with IPF (male 66) were included. Jacobian maps demonstrated constriction of the lung parenchyma marked at the lung base in patients who were deteriorated on visual and PFT assessment. The log_jac values were significantly reduced in the deteriorated patients compared to the stable patients. Mean log_jac values showed positive correlation with baseline percentage of predicted vital capacity (VC%) (r = 0.394, p < 0.05) and percentage of predicted forced vital capacity (FVC%) (r = 0.395, p < 0.05). Additionally, the mean log_jac values were positively correlated with pulmonary vascular volume (r = 0.438, p < 0.01) and the number of pulmonary vascular branches (r = 0.326, p < 0.01).

Conclusions
Elastic registration between baseline and follow-up HRCT was helpful to quantitatively assess the morphological deterioration of lung shrinkage in IPF, and the quantitative indicator log_jac values were significantly correlated with PFTs.

Key Points
• The elastic registration on HRCT was helpful to quantitatively assess the deterioration of IPF.
• Jacobian logarithm was significantly reduced in deteriorated patients and mean log_jac values were correlated with PFTs.
• The mean log_jac values were related to the changes of pulmonary vascular volume and the number of vascular branches.

Published: November 2022

Abstract
Objectives
To systematically investigate the usability of virtual non-contrast reconstructions (VNC) derived from dual-layer CT (DLCT) for detection and size measurements of kidney stones with regards to different degrees of surrounding iodine-induced attenuation and radiation dose.

Methods
Ninety-two kidney stones of varying size (3–14 mm) and composition were placed in a phantom filled with different contrast media/water mixtures exhibiting specific iodine-induced attenuation (0–1500 HU). DLCT-scans were acquired using CTDIvol of 2 mGy and 10 mGy. Conventional images (CI) and VNC0H-1500HU were reconstructed. Reference stone size was determined using a digital caliper (Man-M). Visibility and stone size were assessed. Statistical analysis was performed using the McNemar test, Wilcoxon test, and the coefficient of determination.

Results
All stones were visible on CI0HU and VNC200HU. Starting at VNC400 HU, the detection rate decreased with increasing HU and was significantly lower as compared to CI0HU on VNC≥ 600HU (100.0 vs. 94.0%, p < 0.05). The overall detection rate was higher using 10 mGy as compared to 2 mGy protocol (87.9 vs. 81.8%; p < 0.001). Stone size was significantly overestimated on all VNC compared to Man-M (7.0 ± 3.5 vs. 6.6 ± 2.8 mm, p < 0.001). Again, the 10 mGy protocol tended to show a better correlation with Man-M as compared to 2 mGy protocol (R2 = 0.39–0.68 vs. R2 = 0.31–0.57).

Conclusions
Detection and size measurements of kidney stones surrounded by contrast media on VNC are feasible. The detection rate of kidney stones decreases with increasing iodine-induced attenuation and with decreasing radiation dose as well as stone size, while remaining comparable to CI0HU on VNC ≤ 400 HU.

Key Points
• The detection rate of kidney stones on VNC depends on the surrounding iodine-induced attenuation, the used radiation dose, and the stone size.
• The detection rate of kidney stones on VNC decreases with greater iodine-induced attenuation and with lower radiation dose, particularly in small stones.
• The visibility of kidney stones on VNC≤ 400 HUremains comparable to true-non-contrast scans even when using a low-dose technique.

Published: November 2022

Zusammenfassung
Hintergrund
Gicht ist die häufigste entzündliche Gelenkerkrankung in der westlichen Welt und hat einen bewiesenen genetischen Hintergrund. Zusätzlich tragen Lebensstilfaktoren wie steigende Lebenserwartung und Wohlstand, ausreichende bzw. Überflussernährung und eine steigende Prävalenz von Adipositas in der Bevölkerung sowie z. B. Alkoholkonsum zur steigenden Inzidenz von Hyperurikämie und Gicht bei. Neben einer adäquaten medikamentösen Therapie ist fundierte medizinische Beratung zu Ernährung und Lebensstil ein essenzieller Teil des Managements von Gichtpatienten, die ein hohes Risiko für internistische Komorbiditäten haben.

Ziel
Bereits 2015 hat der Arbeitskreis für Osteoarthritis und Kristallarthropathien in der Österreichischen Gesellschaft für Rheumatologie und Rehabilitation (ÖGR) Ernährungs- und Lebensstilempfehlungen für Patienten mit Gicht und Hyperurikämie publiziert. Seither wurde eine Vielzahl an Arbeiten zu diesem Thema publiziert, was ein Update notwendig machte.

Methoden
Um die seit 2015 publizierte Literatur zu screenen, führten die Autoren zunächst eine hierarchische Literatursuche durch. Unter Berücksichtigung relevanter Zitate der ersten Publikation wurde die relevante Literatur ausgewählt, und die Empfehlungen aus 2015 wurden entweder beibehalten, umformuliert oder neu erstellt. Danach wurden der Evidenzgrad und der Grad der Zustimmung durch die Autoren für jede Empfehlung hinzugefügt.

Ergebnisse
Auf dieser Basis wurden 10 Empfehlungen statt der bisherigen 9 erstellt. Wie in der Erstpublikation wurde eine grafische Darstellung mit Symbolen erstellt, um den Text nonverbal zu ergänzen.

Schlussfolgerung
Die ÖGR-Empfehlungen zu Ernährung und Lebensstil für Patienten mit Gicht und Hyperurikämie wurden entsprechend dem aktuellen Stand der Literatur angepasst. Sie dienen als Informations- und Schulungsmaterial für Patienten und aktualisierte Information für Ärzte.
