Coexistence of solid and liquid phases in shear jammed colloidal drops
Authors: Shah Phalguni , Arora Srishti , Driscoll Michelle M. 
Published: September 2022

AbstractComplex fluids exhibit a variety of exotic flow behaviours under high stresses, such as shear thickening and shear jamming. Rheology is a powerful tool to characterise these flow behaviours over the bulk of the fluid. However, this technique is limited in its ability to probe fluid behaviour in a spatially resolved way. Here, we utilise high-speed imaging and the free-surface geometry in drop impact to study the flow of colloidal suspensions. Here, we report observations of coexisting solid and liquid phases due to shear jamming caused by impact. In addition to observing Newtonian-like spreading and bulk shear jamming, we observe the transition between these regimes in the form of localised patches of jammed suspension in the spreading drop. We capture shear jamming as it occurs via a solidification front travelling from the impact point, and show that the speed of this front is set by how far the impact conditions are beyond the shear thickening transition.

Abstract
Purpose The aim of this retrospective study was to investigate the effect
of subungual glomus tumour size and localization in the germinal or sterile
matrix on tumour recurrence and aesthetic outcomes.
Patients and Methods From 35 patients who underwent surgery for a
subungual glomus tumour between February 2013 and February 2020, 26 patients
– 17 women and 9 men – with 27 subungual glomus tumours
fulfilled the inclusion criteria. The average age was 37.3 (22–58)
years. According to the patients’ surgical notes and preoperative
magnetic resonance images 14 tumours were located in the sterile, 13 in the
germinal matrix, and the mean size of the glomus tumours located in the germinal
matrix was 4.9±1.7 mm, in the sterile matrix
3.6±1.0 mm. At the postoperative 12th month follow-up visit nail
aesthetic was evaluated objectively according to Zook’s fingernail
appearance scoring. In addition, patients were asked to evaluate the pain and
nail appearance in the involved finger by VAS (Visual Analog Scale
0–10). Patients who experienced recurrence were noted.
Results No significant Zook’s fingernail appearance score
differences were observed between germinal and sterile matrix groups
(p=0.097). Comparison of VAS score for pain and VAS score for nail
appearance between the two groups also yielded similar values (p=0.449
and 0.395, respectively). The recurrence rate was similar at both locations
(p=0.557) with 3 recurrences in the germinal, and 2 in the sterile
matrix group. There was no relation between tumour size, Zook’s
fingernail appearance score (p=0.874) and recurrence (p=0.784).
The observed germinal matrix glomus tumours were significantly larger than the
sterile matrix tumours (p=0.031).
Conclusion Neither subungual glomus tumour size nor localization in the
germinal or sterile matrices has different effects on nail appearance and
recurrence.
Idiopathische rekurrierende Perikarditis
Authors: Krusche Martin , Ruffer Nikolas 
Published: September 2022

ZUSAMMENFASSUNGDie idiopathische rekurrierende Perikarditis (IRP) umfasst rezidivierende Perikarditis-Episoden, für die keine anderen Ursachen bzw. Auslöser gefunden werden können. Aufgrund ihres inflammatorischen Charakters (meist akute Schmerzattacken mit deutlich erhöhten serologischen Entzündungszeichen sowie gutem Ansprechen auf Colchicin und/oder Interleukin-1-Blockade) mit Rezidivneigung wird die Erkrankung auch als eigenständige autoinflammatorische Erkrankung angesehen. Darüber hinaus können vergleichbare Episoden auch bei anderen autoinflammatorischen Erkrankungen wie dem familiären Mittelmeerfieber (FMF) oder TNF-Rezeptor-assoziierten periodischen Syndrom (TRAPS) auftreten. Der Artikel gibt einen Überblick über die Klinik, Pathophysiologie und Therapie der IRP.

Published: September 2022

Zusammenfassung
Hintergrund Die Versteifung des Fingerendgelenks ist eine bewährte
Methode zur Behandlung der Endgelenksarthrose. Da es sich bei der oberen
Gliedmaße um eine Gliederkette handelt, die von vernetzten,
gelenkübergreifenden Muskel-Sehnen-Einheiten bewegt wird, sind durch die
Versteifung eines Gelenks Auswirkungen auf die Beweglichkeit und die
Kraftentwicklung beim Greifen zu erwarten. Hierzu fehlt bislang eine
quantitative Analyse in Echtzeit.
Material und Methoden Die Bewegung der Finger und die Kraftentwicklung
beim Greifen wurde an 19 gesunden Probanden mit simulierter Versteifung eines
Fingerendgelenks mit dem TUB-(Technische Universität
Berlin)-Sensorhandschuh beim Faustschluss und bei zwei Varianten des Kraftgriffs
im Vergleich zum physiologischen Griff dynamisch gemessen und quantitativ
analysiert.
Ergebnisse Beim physiologischen Faustschluss betrug der mittlere
Beugungswinkel am Grundgelenk 71,5°, am Mittelgelenk 76,8° und
am Endgelenk 37,3°. Bei simulierter Endgelenksversteifung fiel er am
Mittelgelenk auf 49,6°, während er am Grundgelenk auf
77,3° leicht zunahm. Ebenso verhielt es sich bei den Kraftgriffen. Beim
Kraftgriff I beliefen sich die Winkel unter physiologischen Bedingungen auf
18,3° am Grund-, 39,6° am Mittel- und 42,6° am
Endgelenk. Bei simulierter Endgelenksversteifung stieg der Winkel am Grundgelenk
auf 28,4°, während er am Mittelgelenk auf 25,2° fiel.
Beim Kraftgriff II lagen die physiologischen Werte bei 30,9° am Grund-,
36,6° am Mittel- und 29,0° am Endgelenk. Bei simulierter
Endgelenksversteifung stieg der Winkel am Grundgelenk auf 34,4° und fiel
am Mittelgelenk auf 23,3°. Die bei den Kraftgriffen gemessenen
Kräfte verteilten sich unter physiologischen Bedingungen nahezu
gleichmäßig auf alle vier Strahlen. Bei simulierter
Endgelenksversteifung fiel die gemessene Kraft des betroffenen Fingers im Mittel
nur um bis zu 1,4%.
Schlussfolgerung Mit der vorliegenden Studie liegt erstmals eine
quantitative Analyse des Greifens bei simulierter Endgelenksarthrodese vor. Sie
zeigt das dynamische Zusammenspiel der Fingergelenke sowie der
Kraftverteilungsmuster an den einzelnen Strahlen der Hand in Echtzeit.
Die Therapie der Nahrungsverweigerung und der Anorexia nervosa in
deutschsprachigen Psychiatrie-Lehrbüchern der vergangenen 200
Jahre

Published: September 2022

ZusammenfassungDie vorliegende Arbeit zeigt auf, wie die Therapie der Anorexia nervosa (AN) und
der Nahrungsverweigerung in den führenden Lehrbüchern der
deutschsprachigen Schulpsychiatrie in den vergangenen 200 Jahren vermittelt
wurde. Hierfür wurden 18 Lehrwerke bedeutender Psychiater
ausgewählt. Diese wurden strukturiert analysiert, um jeweils das an
Medizinstudenten und junge Nervenärzte an deutschsprachigen
Universitäten weitergegebene Wissen zur Thematik zu ermitteln. Es zeigte
sich, dass die AN erst Ende des 20. Jahrhunderts als ein eigenständiges
Krankheitsbild erfasst und vermittelt wurde. Doch bereits zuvor wurden der
Nahrungsverweigerung als Symptom eine große Bedeutung beigemessen und
mannigfaltige Therapiekonzepte entwickelt. Beginnend im 19. Jahrhundert mit der
Zwangsernährung mittels Magensonden wurden später
Pharmakotherapien entwickelt sowie spezielle Diäten diskutiert.
Bemerkenswert ist, dass bereits seit den Anfängen der akademischen
Psychiatrie besondere Verhaltensweisen mit dem Patienten und eine
Vorbildfunktion des Therapeuten als „Psychotherapie im weiteren
Sinne“ beschrieben wurden, um Patienten zum Essen zu animieren. Die
Therapie der Nahrungsverweigerung mittels strukturierter Psychotherapien wurde
erst Ende des 20. Jahrhunderts mit der Anerkennung der AN als
eigenständige Krankheitsentität etabliert. Hierbei zeigte sich
im Verlauf der letzten Jahrzehnte ein grundlegender Wandel im
Verständnis von möglichen auslösenden Faktoren dieser
Erkrankung und möglichen psychotherapeutischen Interventionen.

Published: September 2022

Background Radiofrequency ablation (RFA) is effective for eradication of Barrett’s esophagus (BE) neoplasia, but little is known on the course of pain and dysphagia after RFA. We aimed to describe the course of post-RFA symptoms and to identify possible associated risk factors.
Methods In this multicenter, observational cohort study, all RFA procedures registered in a prospective database were included. Patient and treatment characteristics were collected from medical records and patients self-registered post-procedural symptoms in electronic symptom diaries for 14 days. Mixed model regression was used for the analyses.
Results In total, 255 diaries were completed. Post-RFA pain was reported for 95 % (95 %CI 93–98) of procedures (median duration 14 days; 25th–75th percentiles [p25–p75] 11–14) and major pain for 64 % (95 %CI 58–69; median duration 8 days, p25–p75 3–13). Post-procedural pain significantly increased with BE length, younger age, and no prior ablation. Dysphagia was present after 83 % (95 %CI 79–88) of procedures (median duration 13 days, p25–p75 9–14). The risk of dysphagia decreased with age and increased when patients experienced more pain.
Conclusions RFA treatment for BE-related neoplasia seems a significant burden for patients, and post-procedural symptoms should be taken into account when counseling patients before starting endoscopic eradication therapy.
Cranial Base Reconstruction and Secondary Frontal Advancement for Meningoencephalocele Following LeFort III Osteotomy in a Patient with Crouzon Syndrome: Case Report
Authors: Jeon Sungmi , Kim Yumin , Phi Ji Hoon , Chung Jee Hyuk 
Published: September 2022

AbstractPatients with Crouzon syndrome have increased risks of cerebrospinal fluid rhinorrhea and meningoencephalocele after LeFort III osteotomy. We report a rare case of meningoencephalocele following LeFort III midface advancement in a patient with Crouzon syndrome. Over 10 years since it was incidentally found during transnasal endoscopic orbital decompression, the untreated meningoencephalocele eventually led to intermittent clear nasal discharge, frontal headache, and seizure. Computed tomography and magnetic resonance imaging demonstrated meningoencephalocele in the left frontal-ethmoid-maxillary sinus through a focal defect of the anterior cranial base. Through bifrontal craniotomy, the meningoencephalocele was removed and the anterior cranial base was reconstructed with a pericranial flap and split calvarial bone graft. Secondary frontal advancement was concurrently performed to relieve suspicious increased intracranial pressure, limit visual deterioration, and improve the forehead shape. Surgeons should be aware that patients with Crouzon syndrome have the potential for an unrecognized dural injury during LeFort III osteotomy due to anatomical differences such as inferior displacement and thinning of the anterior cranial base.

AbstractAn organocatalytic asymmetric oxa-Michael–Michael reaction of 3-aryl-2-nitroprop-2-enols with alkylidene pyrazolones has been developed. This report describes the first use of a 3-aryl-2-nitroprop-2-enol as an O-nucleophile in enantioselective catalysis. With 10 mol% of a quinine-derived squaramide catalyst, a variety of spirotetrahydropyranopyrazolones were obtained in moderate yields, excellent diastereomeric ratios, and high to excellent enantioselectivities under mild reaction conditions.

Abstract
Background/Aim The importance of an accurate determination of central corneal thickness (CCT) relies on its diagnostic and therapeutic implications in glaucoma, corneal ectasias, corneal edema and endothelial function monitoring, and refractive surgery suitability, among others. We aimed to analyze the repeatability, reproducibility, correlation, and laterality variations of CCT measurements performed with the Pentacam HR and the standard of care ultrasound A-scan (USP).
Methods A cross-sectional study including CCT measurements of healthy individuals was performed by three independent examiners with the Pentacam HR and USP. Intra-observer and inter-observer variations were calculated with intra-class correlation coefficients (ICCs). Bland-Altman plots and 95% limits of agreement (95% LoA) were used to assess the agreement between devices. Linear correlation was calculated with Pearsonʼs coefficient.
Results Thirty individuals (60 eyes), including 10 (33.3%) men and 20 (66.6%) women, with a mean age of 30.0 ± 9.1 years, were studied. No statistical differences were found in CCT measurements between Pentacam HR (range 500 – 609 µm) and USP (range 498 – 628 µm). There was a high degree of correlation in repeatability and reproducibility of each independent device (ICC > 0.90). Pearsonʼs correlation between 1 vs. 2, 2 vs. 3, and 3 vs. 1 Pentacam HR attempts were 0.914, 0.958, and 0.925, respectively (p < 0.001). Corresponding results for USP were 0.957, 0.957, and 0.943 (p < 0.001). The Pentacam HR tended to overestimate CCT by a mean difference of 3.77 µm (95% LoA, − 24.9 – 18.4). Right eyes were also overestimated (− 3.6 ± 14.1 µm) with the Pentacam HR device, whereas left eyes were underestimated (1.3 ± 11.1 µm).
Conclusions The Pentacam HR device provides reliable operator-independent estimates of CCT. Right eyes exhibited a tendency to overestimate with the Pentacam HR. We suspect this difference is due to USP underestimation related to patientsʼ position while performing the study. In clinically relevant scenarios, performing a third measurement and cautiously measuring right eyes can provide higher accuracy.

Published: September 2022

Abstract
Background Introducing an electronic medical record (EMR) system into a complex health care environment fundamentally changes clinical workflows and documentation processes and, hence, has implications for patient safety. After a multisite “big-bang” EMR implementation across our large public health care organization, a quality improvement program was developed and implemented to monitor clinician adoption, documentation quality, and compliance with workflows to support high-quality patient care.
Objective Our objective was to report the development of an iterative quality improvement program for nursing, midwifery, and medical EMR documentation.
Methods The Model for Improvement quality improvement framework guided cycles of “Plan, Do, Study, Act.” Steps included design, pre- and pilot testing of an audit tool to reflect expected practices for EMR documentation that examined quality and completeness of documentation 1-year post-EMR implementation. Analysis of initial audit results was then performed to (1) provide a baseline to benchmark comparison of ongoing improvement and (2) develop targeted intervention activities to address identified gaps.
Results Analysis of 1,349 EMR record audits as a baseline for the first cycle of EMR quality improvement revealed five out of nine nursing and midwifery documentation components, and four out of ten medical documentation components' completion and quality were classified as good (>80%). Outputs from this work also included a framework for strategies to improve EMR documentation quality, as well as an EMR data dashboard to monitor compliance.
Conclusion This work provides the foundation for the development of quality monitoring frameworks to inform both clinician and EMR optimization interventions using audits and feedback. Discipline-specific differences in performance can inform targeted interventions to maximize the effective use of resources and support longitudinal monitoring of EMR documentation and workflows. Future work will include repeat EMR auditing.

AbstractGender-affirming hormones have been shown to improve psychological functioning and quality of life among transgender and nonbinary (trans) people, yet, scant research exists regarding whether and why individuals take more or less hormones than prescribed. Drawing on survey data from 379 trans people who were prescribed hormones, we utilized multivariable logistic regression models to identify factors associated with hormone-dosing behaviors and content analysis to examine the reasons for dose modifications. Overall, 24% of trans individuals took more hormones than prescribed and 57% took less. Taking more hormones than prescribed was significantly associated with having the same provider for primary and gender-affirming care and gender-based discrimination. Income and insurance coverage barriers were significantly associated with taking less hormones than prescribed. Differences by gender identity were also observed. Addressing barriers to hormone access and cost could help to ensure safe hormone-dosing behaviors and the achievement trans people’s gender-affirmation goals.
Ultra-precision machining of cerium-lanthanum alloy with atmosphere control in an auxiliary device
Authors: Zhao Chenyu , Wu Shengjie , Lai Min 
Published: September 2022

Cerium–lanthanum alloys are the main component of nickel–metal hydride batteries, and they are thus an important material in the green-energy industry. However, these alloys have very strong chemical activity, and their surfaces are easily oxidized, leading to great difficulties in their application. To improve the corrosion resistance of cerium–lanthanum alloys, it is necessary to obtain a nanoscale surface with low roughness. However, these alloys can easily succumb to spontaneous combustion during machining. Currently, to inhibit the occurrence of fire, machining of this alloy in ambient air needs to be conducted at very low cutting speeds while spraying the workpiece with a large amount of cutting fluid. However, this is inefficient, and only a very limited range of parameters can be optimized at low cutting speeds; this restricts the optimization of other cutting parameters. To achieve ultraprecision machining of cerium–lanthanum alloys, in this work, an auxiliary machining device was developed, and its effectiveness was verified. The results show that the developed device can improve the cutting speed and obtain a machined surface with low roughness. The device can also improve the machining efficiency and completely prevent the occurrence of spontaneous combustion. It was found that the formation of a build-up of swarf on the cutting tool is eliminated with high-speed cutting, and the surface roughness (Sa) can reach 5.64 nm within the selected parameters. Finally, the oxidation processes of the cerium–lanthanum alloy and its swarf were studied, and the process of the generation of oxidative products in the swarf was elucidated. The results revealed that most of the intermediate oxidative products in the swarf were Ce3+, there were major oxygen vacancies in the swarf, and the final oxidative product was Ce4+.
A New Position Calibration Method for MUSER Images

Published: September 2022

Abstract
The Mingantu Spectral Radioheliograph (MUSER), a new generation of solar dedicated radio imaging-spectroscopic telescope, has realized high-time, high-angular, and high-frequency resolution imaging of the Sun over an ultra-broadband frequency range. Each pair of MUSER antennas measures the complex visibility in the aperture plane for each integration time and frequency channel. The corresponding radio image for each integration time and frequency channel is then obtained by inverse Fourier transformation of the visibility data. However, the phase of the complex visibility is severely corrupted by instrumental and propagation effects. Therefore, robust calibration procedures are vital in order to obtain high-fidelity radio images. While there are many calibration techniques available—e.g., using redundant baselines, observing standard cosmic sources, or fitting the solar disk—to correct the visibility data for the above-mentioned phase errors, MUSER is configured with non-redundant baselines and the solar disk structure cannot always be exploited. Therefore it is desirable to develop alternative calibration methods in addition to these available techniques whenever appropriate for MUSER to obtain reliable radio images. In the case where a point-like calibration source contains an unknown position error, we have for the first time derived a mathematical model to describe the problem and proposed an optimization method to calibrate this unknown error by studying the offset of the positions of radio images over a certain period of the time interval. Simulation experiments and actual observational data analyses indicate that this method is valid and feasible. For MUSER’s practical data the calibrated position errors are within the spatial angular resolution of the instrument. This calibration method can also be used in other situations for radio aperture synthesis observations.
