Liebe Leserinnen und Leser der Osteologie,Die Kenntnis seltener Knochenerkrankungen bringt osteologisch interessierten Kollegen
und Kolleginnen Einsichten in die Mechanismen von Störungen des
Knochenstoffwechsels und deren Behandlung. Nicht alle seltenen Knochenerkrankungen
lassen sich allerdings rein konservativ und medikamentös behandeln,
häufig sind operative Eingriffe und Korrekturen nötig und auch
sinnvoll, um späteren Schäden vorzubeugen.
Ausbau Von Primärversorgungseinheiten In Österreich
– Ein Spieltheoretischer Ansatz
Authors: Busch Anne Maria 
Published: February 2023

ZusammenfassungMit dem Zielsteuerungsvertrag von 2017 haben Bund, Länder und
Sozialversicherung in Österreich den Ausbau von
Primärversorgungseinheiten (PVE) weiter forciert. Mit Stand August 2022
sind von 75 geplanten PVE jedoch erst 36 umgesetzt. Der Artikel gibt mithilfe
von spieltheoretischen Modellen Aufschlüsse darüber, wie sich
der Marktanteil von PVE erhöhen lässt. Die Ergebnisse zeigen,
dass hierfür Kooperationen, ausgeglichene Machtverhältnisse
zwischen den Akteuren und ein Anreiz für Versicherte essentiell sind.
Auch durch öffentliche (Zu-)Zahlungen lassen sich PVE-Marktanteil sowie
Nutzenwerte der Leistungserbringer steigern. Die Ergebnisse können darin
unterstützen, die ab 2022 zur Verfügung stehenden Mittel im
Rahmen des EU-Aufbau- und Resilienzplans zur Attraktivierung und
Förderung der Primärversorgung optimal einzusetzen.
Glycemic Variability and Prognosis of Patients with Intracerebral Hemorrhage: A Meta-Analysis
Authors: Jiao Xu , Wang Huifang , Li Mingfei , Lu Yun 
Published: February 2023

AbstractGlycemic disorder may affect the outcomes of patients with intracerebral hemorrhage (ICH). However, the association between glycemic variability (GV) and prognosis in these patients remains to be determined. We performed a meta-analysis to compressive the influence of GV on functional outcome and mortality in patients with ICH. Observational studies comparing the risks of poor functional outcome (defined as modified Rankin Scale>2) and all-cause mortality between ICH patients with higher versus lower acute GV were retrieved by systematic search of Medline, Web of Science, Embase, CNKI, and Wanfang databases. A random-effect model was used to pool the data after incorporating the between-study heterogeneity. Sensitivity analyses were performed to evaluate the stability of the findings. Eight cohort studies involving 3400 patients with ICH were included in the meta-analysis. The follow-up duration was within 3 months after admission. All of the included studies used standard deviation of blood glucose (SDBG) as the indicator of acute GV. Pooled results showed that ICH patients with higher SDBG were associated with a higher risk of poor functional outcome as compared to those with lower SDBG [risk ratio (RR): 1.84, 95% confidence interval (CI): 1.41 to 2.42, p<0.001, I2=0%]. In addition, patients with higher category of SDBG were also associated with a higher mortality risk (RR: 2.39, 95% CI: 1.79 to 3.19, p<0.001, I2=0%). In conclusion, high acute GV may be a predictor of poor functional outcome and mortality of patients with ICH.
Evidenzbasierte und strukturierte Diagnostik in der MR-Mammografie anhand des Kaiser-Score
Authors: Baltzer Pascal Andreas Thomas , Krug Kathrin Barbara , Dietzel Matthias 
Published: February 2023

Hintergrund Die MR-Mammografie (MRM) ist als sensitivstes Verfahren zur Detektion von Brustkrebs integraler Bestandteil der modernen Mammadiagnostik. Aufgrund umfangreicher multiparametrischer Bildinformationen gilt die Befundung der MRM jedoch als schwierig. Klinische Entscheidungsregeln kombinieren diagnostische Kriterien in einem Algorithmus. Damit unterstützen sie Radiologen dabei, objektive und exakte sowie weitgehend von der Untersuchererfahrung unabhängige MRM-Diagnosen zu stellen.
Methodik Narrativer review. Der Kaiser-Score (KS) als klinische Entscheidungsregel für die MRM wird eingeführt. Befundkriterien werden erläutert, Strategien zur klinischen Entscheidungsfindung diskutiert und illustriert.
Ergebnisse Entwickelt mit Methoden des maschinellen Lernens wurde der Kaiser-Score in internationalen Studien unabhängig validiert. Dabei ist der KS unabhängig von der Untersuchungstechnik. Anhand von auf T2w- und kontrastangehobenen T1w-Aufnahmen fassbaren diagnostischen BI-RADS-Kriterien ermöglicht der KS die objektive und genaue Differenzialdiagnose von benignen und malignen Befunden in der MRM. Ein Flowchart leitet den Leser über maximal 3 Zwischenschritte zu einem Punktwert, entsprechend einer Malignomwahrscheinlichkeit. Damit lässt sich der KS direkt einer konkreten BI-RADS-Kategorie zuordnen. Individuelle Managemententscheidungen sollten dabei auch den klinischen Kontext berücksichtigen, was anhand von typischen Beispielen dargestellt wird.

Hypophosphatasie – Empfehlung einer Expertengruppe zum
Therapievorgehen bei der seltenen Skelett-Erkrankung
Authors: Lampe Christina , Maus Uwe , Scharla Stephan , Schmidmaier Ralf , Schober Hans-Christof , Wüster Christian , Dierks Christian 
Published: February 2023

Abstract
Ziel Für die Hypophosphatasie (HPP) ist Asfotase alfa –
eine Enzymersatztherapie – die derzeit einzige zugelassene
medikamentöse Therapie. Diese Empfehlung soll der Erleichterung der
ärztlichen Therapieentscheidung bei der HPP dienen und Kriterien der
wirtschaftlichen und medizinisch angemessenen Verordnung klären.
Methode Nach der Delphi-Methode wurden die Expertinnen und Experten in
zwei Gruppen aufgeteilt – eine Gruppe erstellte einen Thesenkatalog und
erweiterte diesen textlich. Die zweite Gruppe validierte und editierte den
Entwurf. Dieser Prozess wurde zur Erreichung eines Konsenses wiederholt.
Ergebnisse Die Indikation für eine Therapie mit Asfotase alfa wird
anhand des Schweregrades der Symptome, die sich durch andere Maßnahmen
nicht bessern lassen, gestellt. Voraussetzung für eine Therapie sind
Knochenmanifestationen und das Auftreten von Symptomen der HPP im Kindes- und
Jugendalter. Liegen keine Befunde der HPP im Kindes- und Jugendalter vor, wird
auf eine sorgfältige Anamnese zurückgegriffen. Die Beurteilung,
ob anhand der Anamnese ein Therapieanspruch gerechtfertigt werden kann, obliegt
dem behandelnden Arzt. Es besteht kein Genehmigungsvorbehalt der Krankenkassen.
Wird der Therapieanspruch bestritten, gilt im Sozialrecht der Beweisgrad der
Wahrscheinlichkeit. Auch eine sorgfältig erhobene Verdachtsdiagnose kann
einen Therapieanspruch rechtfertigen.
Fazit Wird die Diagnose der HPP erst im Erwachsenenalter gestellt und
liegen keine weiteren Erkenntnisquellen vor, kann auf eine sorgfältige
Anamnese zum Nachweis des Vorliegens der HPP bereits im Kindes- und Jugendalter
zurückgegriffen werden, um den Anspruch eines Patienten zu
begründen.

Objective We estimated the association between diabetes and shoulder dystocia by infant birth weight subgroups (<4,000, 4,000–4,500, and >4,500 g) in an era of prophylactic cesarean delivery for suspected macrosomia.
Study Design A secondary analysis from the National Institute of Child Health and Human Development U.S. Consortium for Safe Labor of deliveries at ≥24 weeks with a nonanomalous, singleton fetus with vertex presentation undergoing a trial of labor. The exposure was either pregestational or gestational diabetes compared with no diabetes. The primary outcome was shoulder dystocia and secondarily, birth trauma with a shoulder dystocia. We calculated adjusted risk ratios (aRRs) with modified Poison's regression between diabetes and shoulder dystocia and the number needed to treat (NNT) to prevent a shoulder dystocia with cesarean delivery.
Results Among 167,589 assessed deliveries (6% with diabetes), pregnant individuals with diabetes had a higher risk of shoulder dystocia at birth weight <4,000 g (aRR: 1.95; 95% confidence interval [CI]: 1.66–2.31) and 4,000 to 4,500 g (aRR: 1.57; 95% CI: 1.24–1.99), albeit not significantly at birth weight >4,500 g (aRR: 1.26; 95% CI: 0.87–1.82) versus those without diabetes. The risk of birth trauma with shoulder dystocia was higher with diabetes (aRR: 2.29; 95% CI: 1.54–3.45). The NNT to prevent a shoulder dystocia with diabetes was 11 and 6 at ≥4,000 and >4,500 g, versus without diabetes, 17 and 8 at ≥4,000 and >4,500 g, respectively.
Conclusion Diabetes increased the risk of shoulder dystocia, even at lower birth weight thresholds than at which cesarean delivery is currently offered. Guidelines providing the option of cesarean delivery for suspected macrosomia may have decreased the risk of shoulder dystocia at higher birth weights.

Published: February 2023

Abstract
In the current paper, we investigated a spherically symmetric anisotropic solution by applying the gravitational decoupling approach in the context of the vanishing complexity factor condition Contreras and Stuchlik, (2022, Eur Phys J C
82 706) in f(Q) gravity theory for the first time. A relation between the gravitational potentials for a spherically symmetric spacetime in f(Q)-gravity theory has been derived using the vanishing complexity factor condition. To solve the system of equations, we utilized the Tolman metric along with the mimic constraint to density approach. The constants are evaluated by the joining of the spacetime for the interior solution to the Schwarzschild (Anti-) di Sitter exterior spacetime at the boundary. The physical viability of the solution along with its dynamical stability of the solution beyond the f(Q)-gravity theory is tested in order to represent a realistic model. We also discuss the impact of decoupling constants on the maximum mass limit, pressure, and density via equi-contour diagram.

Published: February 2023

Abstract
In this present work, we synthesized WO3-SnO2 and Au decorated WO3-SnO2 nanocomposite by hydrothermal method. The optical characterization has been done by UV/Vis spectroscopy to determine the band gap (Eg) of pure and gold (Au) decorated WO3-SnO2 which shows a reduction in Eg value from 3.56 to 3.03 eV after addition of Au in WO3-SnO2 which improves the crystallinity of WO3-SnO2 . Fourier transformed Infra red (FTIR) spectroscopy has been used to confirm the chemical bonding between Au and WO3-SnO2 nanocomposite. The x-ray Diffraction (XRD) technique was used to study the structural aspects of prepared materials which shows the decrease in crystallite size from 8 to 6.7 nm after addition of Au in pure sample. Field Emission Scanning Electron Microscopy (FESEM) has been used to investigate morphological characteristics of as prepared nanocomposite. The doping of Au was further confirmed by Energy-Dispersive x-ray spectroscopy (EDS) technique. The sensing properties have been studied from the I–V measurement of WO3-SnO2/Au nanocomposite for Benzene. The sensing parameters such as sensitivity (response), operating temperature and response and recovery time were calculated for benzene vapors. The addition of Au in WO3-SnO2 increases its response to 2.7 times for 100 ppm benzene with a reduction in response/recovery time from 18/50 s to 13/29 s. The operating temperature was 300 °C. Further, the material is highly selective for benzene as compared to cyclohexane, toluene and aniline.
Revealing ultra-high-energy cosmic ray acceleration with multi-messenger observations of the nearby GRB 980425/SN 1998bw
Authors: Mirabal Nestor 
Published: February 2023

Abstract
The origin of ultra-high energy cosmic rays (UHECRs) is
one of the most mystifying issues in astroparticle physics. It has been suggested that gamma-ray bursts (GRBs) are excellent acceleration sites for cosmic rays.
The propagation of UHECRs from the GRB host galaxy to the Earth should generate delayed secondary photons and neutrinos. Here we present a dedicated search for delayed UHECR and neutrino emission centered around the position of nearby GRB 980425/SN 1998bw. Located at a distance of 36.9 Mpc, GRB 980425/SN 1998bw is well within the Greisen-Zatsepin-Kuzmin (GZK) distance horizon.
We find no evidence for UHECR or neutrino clustering around the GRB 980425/SN 1998bw position between 2004 and 2020. Under ideal propagation conditions, we propose that it might be possible to detect an excess from delayed UHECRs around GRB 980425/SN 1998bw within the next 100 years if the intergalactic magnetic field (IGMF)
strength is B ≤ 3 × 10-13 G.
Frequency-domain elastic full-waveform inversion based on Green functions
Authors: Zhang Wensheng 
Published: February 2023

Abstract
In this paper, the elastic full-waveform inversion in the frequency domain based on Green functions is investigated. The method allows to image media velocities of compressional wave and shear wave by using vertical and horizontal components. The forward problem is solved by the finite difference scheme with the perfectly matched layer in the frequency domain. The inversion is an optimization iterative process to minimize the residual between the synthetic data and the observed data on the surface. A gradient method is used to find the optimization direction, preconditioned with the diagonal part of the inverse Hessian matrix. The gradient is constructed based on Green functions, which serves to compute the gradient of the objective function with respect to model parameters effectively. The inversion is completed from low frequency to high frequency so that smaller wavelengths are progressively introduced in inversion. Numerical computations for the benchmark Overthrust model demonstrate the full-waveform inversion method in this paper can inverse media velocities of complex structures accurately.
Monotonicity Principle for Tomography in Nonlinear Conducting Materials
Authors: Esposito Antonio Corbo , Faella Luisa , Piscitelli Gianpaolo , Prakash Ravi , Tamburrino Antonello 
Published: February 2023

Abstract
In this paper, we deal with an inverse electrical conductivity problem which considers the reconstruction of nonlinear electrical conductivity in steady currents operations using boundary measurements. In the current set up, we establish a monotonic relation between the unknown material property to the (measured) Dirichlet-to-Neumann operator (DtN). It is in fact the Monotonicity Principle which is the base of a class of non-iterative and real-time imaging methods and algorithms. To be more precise, we indicate the issues appear in our nonlinear case to transfer this Monotonicity result from the Dirichlet Energy to the DtN operator which is the fundamental huddle in comparison to linear and p-Laplacian cases. Finally, we introduce a new Average DtN operator which is different from the existing ones and resolves complications produced by non-linearity in our problem.
Magnetic induction tomography via the monotonicity principle
Authors: Piscitelli Gianpaolo , Su Zhiyi , Udpa Lalita , Tamburrino Antonello 
Published: February 2023

Abstract
This contribution is focused on the nonlinear and ill-posed problem of reconstructing the electrical conductivity starting from the free response of a conductor in the magneto-quasi-stationary (MQS) limit. In this framework, a key role is played by the Monotonicity Principle, that is a monotone relation connecting the unknown material property to the (measured) free-response. The Monotonicity Principle is relevant to develop noniterative and real-time imaging methods. The Monotonicity Principle is a rather general principle found in many different physical problems. However, each physical/mathematical context requires the proper operator showing the MP to be identified. In turns, this calls for ad-hoc mathematical approaches tailored to the specific frameworks. In this paper we discuss a monotonic relationship between the electrical resistivity and the time constants of the free response for MQS systems. Numerical examples are provided to support the underlying theory.
Constitutive material law improvements for metals that manifest an unstable behavior in dynamic condition
Authors: Mancini E , Sasso M , Farotti E , Amodio D 
Published: February 2023

Abstract
Numerical analysis is regularly used in engineering practice as useful mean to study component behavior in service, especially when an experimental campaign is too expensive or not practicable. Numerical software is becoming more and more powerful and integrated, leaving the correct use of a material model as a weak point. As some materials could manifest an unstable behavior if deformed at high strain rate, it is of primary importance to use an appropriate constitutive law to reproduce their behaviour. This paper shows the results of the inverse calibration of two material (Ti-4Al-6V and AA 7075-T6) constitutive laws in their classical definition, as present in the literature. Moreover, both of them have been modified by the authors in the attempt of improving the complex material behaviour. The calibrated models are Johnson-Cook (JC) and Nowak-Pecherski (NP) models. The improvement of these models showed that JC is not suitable for calibrate materials that show an unstable behavior also after its improvement; conversely NP provided a better matching with the experimental data.

Published: February 2023

Abstract
An effective analysis method with multiple accelerant factors is needed for rapid shelf-life determination for foods. This study aimed to investigate the effect of environmental oxygen pressure on oxygen diffusivity in polyethylene terephthalate (PET), high-density polyethylene (HDPE) and polypropylene (PP) bottles. The bottles were placed in custom-made high-pressure (10–30 psig) chambers with a 100% oxygen environment after filled with water and flushed with nitrogen to reduce the internal oxygen level below 2%. Bottles were subjected to three pressure levels and the accumulation of headspace and dissolved oxygen was used to estimate the diffusivity with the inverse problems approach. Modelling of diffusion was performed by numerically solving Fick’s law and the sequential estimation of the diffusion coefficient was performed based on the Gauss minimization method. The oxygen diffusion coefficient of PET, HDPE and PP was in the range of 0.78−1.16x10−13 m2s−1, 0.14−0.46x10−13 m2s−1 and 0.59−14.09x10−16 m2s−1, respectively. The application of oxygen pressure significantly increased the rate of oxygen transfer for all packaging materials compared to the control samples at ambient pressure. The application of inverse problems enabled the determination of the diffusion coefficient of oxygen with minimal errors and small confidence intervals. The use of elevated pressure and temperature as accelerants has potential application in rapid shelf-life determination of foods.

Published: February 2023

Abstract
Extreme weather, such as wind and ice, threatens the safety and stability of transmission networks. In this paper, the joint probability distribution model of wind speed and ice thickness are established, based on which the bearing capacity of a transmission tower under combined wind and ice loads are evaluated. The results show that the developed probability distribution models can well characterize the dependence structure of wind speed and ice thickness, and the safety of the transmission tower under combined wind-ice loads can be guaranteed within its design life.

Published: February 2023

Abstract
Aviation fuel pipeline is one of the important lifelines of aviation coal supply at airports. When crossing a densely populated area, the aviation oil pipeline will inevitably be disturbed by natural and human factors, such as unreasonable soil accumulation near the pipeline, when the soil load is too large, the weak foundation soil will produce different degrees of deformation, the pipeline is subjected to various complex force forms under the action of soil displacement, resulting in a series of damage to the pipeline, and eventually cause pipeline safety accidents, resulting in the loss of people’s lives and property and environmental damage. Therefore, studying the force characteristics and safety prevention and control countermeasures of buried aviation oil pipelines under the surrounding soil pile occupation pressure has a very important guiding role and practical value for ensuring the operation safety of the airport lifeline. In this paper, the stress and deformation of buried oil and gas pipelines under the action of surrounding soil piles are analyzed, the influencing factors of buried oil and gas pipeline stress under the action of soil accumulation are analyzed by finite element software ABAQUS, the detailed stress analysis of the pipeline is carried out,and the finite element simulation method is verified by on-site large-scale stacking tests.

Published: February 2023

Abstract
Significant scientific effort has been focused on optimizing the scenarios and plasma parameters for tokamak operations. The lack of comprehensive understanding of underlying physical processes leads to simplifications used both in plasma simulation codes and for diagnostics, which is also complicated by the harsh plasma environment. One of the main tools to couple, check and verify these assumptions are the synthetic diagnostics. In this work we demonstrate current results of the development of the set of synthetic diagnostics for the WEST tokamak to couple experimental data with the SolEdge3X-HDG 2D transport code.
