ZusammenfassungDie hohe Prävalenz von Rückenbeschwerden in der
Bevölkerung, insbesondere von Schmerzen im Bereich der
Lendenwirbelsäule, hat negative Auswirkungen auf die individuelle
Lebensqualität und Fehlzeiten am Arbeitsplatz. Als mögliche
Ursachen wurden unter anderem eine verminderte Rumpfkraft und/oder eine
schlechte neuromuskuläre Ansteuerung beschrieben. Zur Vorbeugung oder
Therapie von Rückenschmerzen sind Übungen zur Stärkung
der Rumpfmuskulatur in Kombination mit einer adäquaten
neuromuskulären Ansteuerung entscheidend. Der Gymnastikball hat sich
dabei als effizientes Trainingsmittel erwiesen. Die zunehmende Digitalisierung
ermöglicht im Bereich der therapeutischen Maßnahmen und des
Trainings vermehrt die Implementierung von kostengünstigen
Miniatur-Sensoren mit dazugehörenden Apps. In diesem Praxisbeitrag wird
ein neuartiges Stabilisations- und Gleichgewichtstraining im Sitzen auf einem
Gymnastikball mit integriertem Bewegungssensor und dazugehöriger
Trainings-App vorgestellt. Dazu wird ein flexibler Gurt, in welchen ein kleiner
dreidimensionaler Neigungssensor integriert ist, um den Gymnastikball gelegt.
Dadurch können die Bewegungen des Gymnastikballs mit einer Abtastrate
von 100 Hz erfasst werden. Die Bewegungsdaten werden über
Bluetooth in die Trainings-App auf ein Tablet oder Handy übertragen.
Nach einer Kalibrierung der Sensorposition erscheinen die Menüpunkte
Balance, Training sowie Spiele am Bildschirm. Ziel bei den vorgegebenen
Übungen ist es, die auf dem Bildschirm vorgegebenen Bewegungen bzw.
Positionen durch vom Neigungssensor erfasste (feinmotorische) Bewegungen auf dem
Gymnastikball nachzustellen. Konkret geht es darum, dass der Übende den
über Echtzeitfeedback am Tablet dargestellten grünen Steuerkreis
möglichst schnell in den sich bewegenden oder unbewegten blauen
Zielkreis steuert und der Bewegung folgt oder die Position hält. In den
Menüpunkten Balance und Training können drei
Schwierigkeitsstufen mit bis zu 13 Übungen bei einer Übungsdauer
von ca. fünf Minuten ausgewählt werden. Eine Besonderheit im
Trainingsmodus stellt die Möglichkeit eines gespiegelten Trainings dar.
Gespiegeltes Training bedeutet, dass die vorgegebenen Bewegungen des Zielkreises
von der trainierenden Person in die jeweils entgegengesetzte Richtung
ausgeführt werden müssen. Die Trainings-App stellt, speziell
für die jüngeren Personen, sechs einfache Feedbackspiele am
Gymnastikball bereit. Somit bietet das neue sensorbasierte Feedbacktraining am
Gymnastikball eine kostengünstige, anwenderfreundliche
Einsatzmöglichkeit mit motivierenden und zielgerichteten Übungen
für den Gesundheits-, Fitness- und Rehabilitationsbereich.
CACP: eine seltene Differenzialdiagnose der juvenilen idiopathischen Arthritis
Authors: Sprengel Anthony , Haas Johannes-Peter 
Published: December 2021

ZusammenfassungDas Kampodaktylie-Arthropathie-Coxa-vara-Perikarditis (CACP) -Syndrom ist eine seltene, autosomal-rezessive Erkrankung, die auf Mutationen im Proteoglycan-4-Gen zurückzuführen ist (OMIM #208250). Im Krankheitsverlauf steht eine progrediente, nicht inflammatorische Arthropathie im Vordergrund, wobei manche Patienten eine kardiale Beteiligung entwickeln. Berichtet wird über einen 3½-jährigen Jungen und ein 6-jähriges Mädchen, die unter der Diagnose einer therapieresistenten Rheumafaktor-negativen Polyarthritis mit intensiver antirheumatischer Behandlung erstmals im Deutschen Zentrum für Kinder- und Jugendrheumatologie vorgestellt wurden. Beide Patienten wiesen typische klinische Symptome eines CACP auf. Anhand anamnestischer Hinweise und einzelner diagnostischer Schritte konnte diese seltene Erkrankung zunächst eingegrenzt und in einem weiteren Schritt durch eine genetische Diagnostik bei beiden Kindern belegt werden.

Authors: Banys-Paluchowski Maggie , Krawczyk Natalia , Fehm Tanja 
Published: December 2021

ZusammenfassungIn den letzten Jahren gewinnt die Liquid Biopsy, d. h. die blutbasierte Untersuchung von zirkulierenden Tumorzellen (CTCs) und Nukleinsäuren (DNA/RNA) beim Mammakarzinom zunehmend an Relevanz. Zahlreiche Studien haben bereits die hohe prognostische Bedeutung der CTC-Detektion sowohl im frühen als auch metastasierten Stadium gezeigt. Des Weiteren korrelieren die Veränderungen der CTC-Zahlen und der zirkulierenden Tumor-DNA (ctDNA) im Verlauf der Erkrankung mit dem Ansprechen auf die Therapie. Im Fokus der Forschung stehen derzeit die Liquid-Biopsy-basierten Therapieinterventionen beim metastasierten Mammakarzinom. In diesem Kontext wurde Alpelisib, ein PI3K-Inhibitor, als erste Substanz durch die FDA und die EMA zugelassen.

Published: December 2021

ResumoA primeira sutura meniscal foi realizada em 1885 e levou cerca de um século para tornar-se popular. Atualmente, os dispositivos de reparo meniscal all-inside são amplamente utilizados. Contudo, esta técnica apresenta a desvantagem de ser um método dependente de dispositivos específicos, apresentando um custo superior aos de outras técnicas. Este valor elevado limita o uso de tal técnica em muitos locais. O objetivo da presente nota técnica é descrever uma técnica de sutura meniscal microinvasiva, como uma modificação da técnica all-inside, utilizando uma agulha descartável de procedimento de 40 × 12 mm. Os autores acreditam que a modificação proposta para a técnica pode torná-la mais popular, possibilitando o uso da técnica microinvasiva em locais com recursos limitados.
A Comparison of Vaginal and Intramuscular Progesterone for the Prevention of Recurrent Preterm Birth

Published: December 2021

Objective This study aimed to examine whether vaginal progesterone is noninferior to 17-α hydroxyprogesterone caproate (17OHP-C) in the prevention of recurrent preterm birth (PTB).
Study Design This retrospective cohort study included singleton pregnancies among women with a history of spontaneous PTB who received prenatal care at a single tertiary center from 2011 to 2016. Pregnancies were excluded if progesterone was not initiated prior to 24 weeks or the fetus had a major congenital anomaly. The primary outcome was PTB <37 weeks. A priori, noninferiority was to be established if the upper bound of the adjusted two-sided 90% confidence interval (CI) for the difference in PTB fell below 9%. Inverse probability of treatment weighting (IPTW) was used to carefully control for confounding associated with choice of treatment and PTB. Adjusted differences in PTB proportions were estimated via IPTW regression, with standard errors adjustment for multiple pregnancies per woman. Secondary outcomes included PTB <34 and <28 weeks, spontaneous PTB, neonatal intensive care unit admission, and gestational age at delivery.
Results Among 858 pregnancies, 41% (n = 353) received vaginal progesterone and 59% (n = 505) were given 17OHP-C. Vaginal progesterone use was more common later in the study period, and among women who established prenatal care later, had prior PTBs at later gestational ages, and whose race/ethnicity was neither non-Hispanic white nor non-Hispanic Black. Vaginal progesterone did not meet noninferiority criteria compared with 17-OHPC in examining PTB <37 weeks, with an IPTW adjusted difference of 3.4% (90% CI: −3.5, 10.3). For secondary outcomes, IPTW adjusted differences between treatment groups were generally small and CIs were wide.
Conclusion We could not conclude noninferiority of vaginal progesterone to 17OHP-C; however, women and providers may be willing to accept a larger difference (>9%) when considering the cost and availability of vaginal progesterone versus 17OHP-C. A well-designed randomized trial is needed.

Alstrom's Syndrome: An Experience of Tertiary Care Center
Authors: Gosadi Ghadah , Busehail Maryam , Rahbeeni Zuhair 
Published: December 2021

AbstractAlstrom's syndrome (AS) is an autosomal recessively inherited multisystemic disorder that falls under the umbrella of ciliopathy. It is characterized by poor vision, hearing impairment, cardiomyopathy, childhood obesity, diabetes mellitus type 2, dyslipidemia, pulmonary, hepatic, and renal failure besides systemic fibrosis. Biallelic pathogenic variants in ALMS1 gene cause AS. Retrospective study (1990–2017) included 12 Saudi patients with AS based on their phenotype, biochemical markers, and genotype. The study was approved by Fisal Specialist Hospital and Research Centre, Riyadh (RAC number 2131129) on October 2, 2012. This study showed clinical and genetic heterogeneity; six patients showed a founder mutation (IVS18–2A > T in exon 19), whereas six others showed private mutations. AS in Saudi Arabia is underdiagnosed probably because of its variable clinical manifestations. We report 12 Saudi patients with AS to enhance the awareness about this syndrome.
Interclausal relations with Old English verbs of inaction
Authors: Ojanguren López Ana Elvira 
Published: December 2021

Abstract
The aim of this article is to analyse the syntactic and semantic interclausal relations that hold with Old English verbs
of inaction. These verbs are studied from the perspective of juncture-nexus relations and the semantic relations Phase, Psych-action and
Causative. The results are compared on the grounds of the Interclausal Relations Hierarchy. The comparison of semantic content and syntactic
expression evidences discrepancies between too weak juncture-nexus types, such as clausal subordination, and very close semantic relations,
like Phase. Two main conclusions are drawn. Firstly, the Interclausal Relations Hierarchy allows us to describe the variation in the
complementation of inaction verbs in Old English; and to make predictions on the diachronic axis, given that the loss of finite clause
complementation and the change to infinitival complementation presented by Present-Day English verbs of inaction are fully predicted by the
IRH. Secondly, semantic relations and nexus types remain stable throughout the change, whereas juncture levels change.

Differential sampling of AC waveforms based on a programmable Josephson voltage standard using a high-precision sampler
Authors: Kim Mun-Seog , Cho Hehree , Solve Stéphane 
Published: December 2021

Abstract
A high-precision sampler, Fluke 8588A multimeter in the sampling mode, was utilised to perform differential sampling of AC waveforms with a programmable Josephson voltage standard. The systematic error on the differential sampling, induced by the inherent voltage-response characteristics and built-in low-pass filter of the sampler, was estimated. Experimental results and numerical simulations revealed that the sampler could be used for reliable differential sampling of AC waveforms at frequencies up to several kilohertz, with an appropriate number of the voltage steps per the waveform period, when the input bandwidth was set to 3 MHz. In addition, the sampler was compared to an integrating sampler, Keysight 3458A, now widely used for differential sampling. At 62.5 Hz, a key frequency in the future on-site key comparison of the differential sampling on AC voltage, the difference in root mean square (RMS) amplitudes obtained by the differential sampling using the two different samplers is approximately 150 nV V−1 due to the systematic error caused by the limited bandwidth of 150 kHz for the integrating sampler.
X-ray imaging of moving objects using on-chip TDI and MDX methods with single photon counting CdTe hybrid pixel detector
Authors: Zoladz M. , Grybos P. , Szczygiel R. 
Published: December 2021

Abstract
X-ray imaging of moving objects using line detectors remains the most popular method of object content and structure examination with a typical resolution limited to 0.4–1 mm. Higher resolutions are difficult to obtain as, for the detector in the form of a single pixel row, the narrower the detector is, the lower the image Signal to Noise Ratio (SNR). This is because, for smaller pixel sizes, fewer photons hit the pixel in each time unit for a given radiation intensity.
To overcome the trade-off between the SNR and spatial resolution, a two-dimensional sensor, namely a pixel matrix can be used. Imaging of moving objects with a pixel matrix requires time-domain integration (TDI). Straightforward TDI implementation is based on the proper accumulation of images acquired during consecutive phases of an object’s movement. Unfortunately, this method is much more demanding regarding data transfer and processing. Data from the whole pixel matrix instead of a single pixel row must be transferred out of the chip and then processed.
The alternative approach is on-chip TDI implementation. It takes advantage of photons acquired by multiple rows (a higher SNR), but generates similar data amount as a single pixel row and does not require data processing out of the chip. In this paper, on-chip TDI is described and verified by using a single photon counting two-dimensional (a matrix of 128 × 192 pixels) CdTe hybrid X-ray detector with the 100 µm × 100 µm pixel size with up to four energy thresholds per pixel. Spatial resolution verification is combined with the Material Discrimination X-ray (MDX) imaging method.

Published: December 2021

Abstract
A python package, called Tomotok, focused on performing tomographic inversion of tokamak plasma radiation is being developed at the Institute of Plasma Physics of the Czech Academy of Sciences. It aims at providing multiple inversion algorithms with an user friendly interface. In order to enable and ease performing tomographic inversion on different devices worldwide, it is planned to publish this software as open source in the near future. In this contribution, the package structure allowing an easy implementation of various tokamak and diagnostic geometries is described and an overview of the package contents is given. Apart from inversion methods, overview of Tomotok auxiliary content is given. The package provides tools for creating simple synthetic diagnostic system. These can be used for testing and benchmarking the code. This includes tools for building geometry matrices that describe the view of detectors using single line of sight approximation and artificial data generators capable of creating simple or hollow Gaussian profiles. The implemented inversion methods cover the minimum Fisher regularisation, biorthogonal decomposition and linear algebraic methods. The implementation of each method is explained, example results obtained by inverting phantom models are presented and discussed. The computation speed of implemented algorithms is benchmarked and compared.
Performance study of large-area glass resistive plate chambers with different spacer configurations
Authors: Mao L. , Lagarde F. , Guo J. , Wang X. , Li J. , Shen Q. , Zhu J. , Yang H. 
Published: December 2021

Abstract
Optimization of spacer and gas distribution inside the glass
resistive plate chamber (RPC) is reported. Simulation studies
demonstrate improvements on the gas flow velocity homogeneity and
lower vorticity inside the gas chamber. The optimized spacer
configuration (76 spacers) decreases the number of spacers by 24%
compared to the original design (100 spacers), thus helps
significantly reduce the non-active or low-efficiency area caused by
spacers while maintaining similar deformation uniformity of the
electrodes. Large area glass RPCs with 1×1 m^2 size using
two types of spacer configurations are constructed and tested with
cosmic muons events. The muon detection efficiencies for RPCs are
greater than 95%.
Design and verification of a multi-layer single-sphere neutron spectrometer with water as the moderator
Authors: Li X. , Wang Z. , Qi P. , Chen X. , Gao T. , Zhou R. , Yang C. 
Published: December 2021

Abstract
Measuring the neutron energy spectrum is important in
nuclear radiation detection and protection. Common neutron
spectrometers include the Bonner sphere spectrometer (BSS),
time-of-flight neutron spectrometer, and plastic scintillation
detector. Among them, the BSS is the most widely used for its wide
measurement range and simple operation. A BSS usually occupies a
large space because it contains several independent spheres working
at the same time, leading to poor consistency. This paper proposes a
multi-layer single-sphere spectrometer using water as the
moderator. The spectrometer includes a multi-layered sphere that can
be filled with water or air and a ^3He proportional counter
placed in the center of the sphere. To verify the feasibility of
this design, we use Geant4 to calculate the moderating ability of
water and the response functions of the multi-layer single-sphere
spectrometer. Additionally, several standard neutron energy spectra
(from IAEA) are used to test the response characteristics of this
spectrometer through simulation. The simulation results prove the
feasibility of the design. This research provides a theoretical
basis for a multi-layer single-sphere neutron spectrometer with
water as the moderator.
Jacobi ﬁelds in nonholonomic mechanics

Published: December 2021

Abstract
In this paper, we deﬁne Jacobi ﬁelds for nonholonomic mechanics using a similar characterization than in Riemannian geometry. We give explicit conditions to ﬁnd Jacobi ﬁelds and ﬁnally we ﬁnd the nonholonomic Jacobi fields in two equivalent ways: the ﬁrst one, using an appropriate complete lift of the nonholonomic system and, in the second one, using the curvature and torsion of the associated nonholonomic connection.
