Context. Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties (size and shape) of the largest members can be readily accessed by large (8m class) telescopes.
Aims. We took advantage of the bright apparition of the most iconic member of the Cybele population, (65) Cybele, in July and August 2021 to acquire high-angular-resolution images and optical light curves of the asteroid with which we aim to analyse its shape and bulk properties.
Methods. Eight series of images were acquired with VLT/SPHERE+ZIMPOL, seven of which were combined with optical light curves to reconstruct the shape of the asteroid using the ADAM, MPCD, and SAGE algorithms. The origin of the shape was investigated by means of N-body simulations.
Results. Cybele has a volume-equivalent diameter of 263±3 km and a bulk density of 1.55 ± 0.19 g cm−3. Notably, its shape and rotation state are closely compatible with those of a Maclaurin equilibrium figure. The lack of a collisional family associated with Cybele and the higher bulk density of that body with respect to other large P-type asteroids suggest that it never experienced any large disruptive impact followed by rapid re-accumulation. This would imply that its present-day shape represents the original one. However, numerical integration of the long-term dynamical evolution of a hypothetical family of Cybele shows that it is dispersed by gravitational perturbations and chaotic diffusion over gigayears of evolution.
Conclusions. The very close match between Cybele and an equilibrium figure opens up the possibility that D ≥ 260 km (M ≥ 1.5 × 1019 kg) small bodies from the outer Solar System all formed at equilibrium. However, we cannot currently rule out an old impact as the origin of the equilibrium shape of Cybele. Cybele itself is found to be dynamically unstable, implying that it was ‘recently’ (<1 Gyr ago) placed on its current orbit either through slow diffusion from a relatively stable orbit in the Cybele region or, less likely, from an unstable, Jupiter-family-comet orbit in the planet-crossing region.
Numerical simulations of MHD jets from Keplerian accretion disks
Authors: Jannaud T. , Zanni C. , Ferreira J. 
Published: December 2022

Context. The most successful scenario for the origin of astrophysical jets requires a large-scale magnetic field anchored in a rotating object (black hole or star) and/or its surrounding accretion disk. Platform jet simulations, where the mass load onto the magnetic field is not computed by solving the vertical equilibrium of the disk but is imposed as a boundary condition, are very useful for probing the jet acceleration and collimation mechanisms. The drawback of such simulations is the very large parameter space: despite many previous attempts, it is very difficult to determine the generic results that can be derived from them.
Aims. We wish to establish a firm link between jet simulations and analytical studies of magnetically driven steady-state jets from Keplerian accretion disks. In particular, the latter have predicted the existence of recollimation shocks – due to the dominant hoop stress –, which have so far never been observed in platform simulations.
Methods. We performed a set of axisymmetric magnetohydrodynamics (MHD) simulations of nonrelativistic jets using the PLUTO code. The simulations are designed to reproduce the boundary conditions generally expected in analytical studies. We vary two parameters: the magnetic flux radial exponent α and the jet mass load κ. In order to reach the huge unprecedented spatial scales implied by the analytical solutions, we used a new method allowing us to boost the temporal evolution.
Results. We confirm the existence of standing recollimation shocks at large distances. As in self-similar studies, their altitude evolves with the mass load κ. The shocks are weak and correspond to oblique shocks in a moderately high, fast magnetosonic flow. The jet emitted from the disk is focused toward the inner axial spine, which is the outflow connected to the central object. The presence of this spine is shown to have a strong influence on jet asymptotics. We also argue that steady-state solutions with α ≥ 1 are numerically out of range.
Conclusions. Internal recollimation shocks may produce observable features such as standing knots of enhanced emission and a decrease in the flow rotation rate. However, more realistic simulations (e.g. fully three-dimensional) must be carried out in order to investigate nonaxisymmetric instabilities and with ejection only from a finite zone in the disk, so as to to verify whether these MHD recollimation shocks and their properties are maintained.

Abstract
Purpose This is an official guideline, published and coordinated by the Germany Society for Gynecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG).
Because of their rarity and heterogeneous histopathology, uterine sarcomas are challenging in terms of their clinical management and therefore require a multidisciplinary approach. To our
knowledge, there are currently no binding evidence-based recommendations for the appropriate management of this heterogeneous group of tumors.
Methods This S2k guideline was first published in 2015. The update published here is once again the result of the consensus of a representative interdisciplinary committee of experts
who were commissioned by the Guidelines Committee of the DGGG to carry out a systematic search of the literature on uterine sarcomas. Members of the participating professional societies
achieved a formal consensus after a structured consensus process.
Recommendations 1.1 Epidemiology, classification, staging of uterine sarcomas. 1.2 Symptoms, general diagnostic workup, general pathology or genetic predisposition to uterine
sarcomas. 2. Management of leiomyosarcomas. 3. Management of low-grade endometrial stromal sarcomas. 4. Management of high-grade endometrial stromal sarcoma and undifferentiated uterine
sarcomas. 5. Management of adenosarcomas. 6. Rhabdomyosarcomas of the uterus in children and adolescents. 7. Follow-up of uterine sarcomas. 8. Management of morcellated uterine sarcomas. 9.

“My Brigham Baby” Application: A Pilot Study Using Technology to Enhance Parent's Experience in the Neonatal Intensive Care Unit
Authors: Erdei Carmina , Forde Madison , Cherkerzian Sara , Conley Maria S. , Liu Cindy H. , Inder Terrie E. 
Published: December 2022

Objective This study aimed to describe the family psychosocial experience in a level-III neonatal intensive care unit (NICU), and to assess how it evolved after rollout of an educational smartphone application (App) called “My Brigham Baby.”
Study Design We surveyed 25 NICU parents pre-App rollout (before coronavirus disease 2019 [COVID-19] pandemic) and 25 parents post-App rollout (during pandemic). Collected data included parental self-reported discharge readiness, symptoms of stress and anxiety, and parenting skill confidence. Survey scores were assessed as total or mean scores, and by category of severity.
Results Pre-and post-App parents had comparable demographics, and their infants had similar clinical characteristics during their NICU stay. Discharge readiness differed by group status (p = 0.02) and was characterized by a greater frequency in being “very ready” for discharge among the post-App rollout parent group compared with the pre-App group (56 vs. 20%, p = 0.027), and parenting confidence shifted toward more optimal scores post-App rollout. Parental stress and anxiety symptoms did not significantly differ between groups despite possible stress contagion from the COVID-19 pandemic.
Conclusion This pilot study suggests that technology Apps are feasible interventions within NICU settings and may enhance parental experiences related to NICU hospitalization.

Published: December 2022

Abstract
Background Stereotactic radiosurgery (SRS) and resection are treatment options for patients with facial nerve schwannomas without mass effect.
Objective This article evaluates outcomes of patients treated with SRS versus resection + SRS.
Method We retrospectively compared 43 patients treated with SRS to 12 patients treated with resection + SRS. The primary study outcome was unfavorable combined endpoint, defined as worsening or new clinical symptoms, and/or tumor radiological progression. SRS (38.81 ± 5.3) and resection + SRS (67.14 ± 11.8) groups had similar clinical follow-ups.
Results At the time of SRS, the tumor volumes of SRS (mean ± standard error; 1.83 ± 0.35 mL) and resection + SRS (2.51 ± 0.75 mL) groups were similar. SRS (12.15 ± 0.08 Gy) and resection + SRS (12.16 ± 0.14 Gy) groups received similar radiation doses. SRS group (42/43, 98%) had better local tumor control than the resection + SRS group (10/12, 83%, p = 0.04). Most of SRS (32/43, 74%) and resection + SRS (10/12, 83%) group patients reached a favorable combined endpoint following SRS (p = 0.52). Considering surgical associated side effects, only 2/10 patients of the resection + SRS group reached a favorable endpoint (p < 0.001).Patients of SRS group, who are > 34 years old (p = 0.02), have larger tumors (> 4 mL, 0.04), internal auditory canal (IAC) segment tumor involvement (p = 0.01) were more likely to reach an unfavorable endpoint. Resection + SRS group patients did not show such a difference.
Conclusion While resection is still needed for larger tumors, SRS offers better clinical and radiological outcomes compared to resection followed by SRS for facial schwannomas. Younger age, smaller tumors, and non-IAC situated tumors are factors that portend a favorable outcome.
Copper-Catalyzed Decarboxylative Cascade Cyclization for the Synthesis of 2-Arylquinolines
Authors: Chatterjee Rana , Pothireddy Mohanreddy , Dandela Rambabu 
Published: December 2022

AbstractAn efficient copper-catalyzed intermolecular decarboxylative cascade cyclization has been developed that uses readily accessible starting materials and less-expensive reagents. A one-pot reaction of an aryl aldehyde, an aniline, and acrylic acid permits the direct synthesis of 2-substituted quinolines through the sequential formation of C–N and C–C bonds. Furthermore, the three-component, one-pot, domino strategy features promising chemo- and regioselectivity and also tolerates a wide variety of substrates with excellent functional-group tolerance, high yields, a radical reaction pathway, and aerobic reaction conditions.

Published: December 2022

AbstractThe stereoselective synthesis of several secondary propargylamines by the copper-promoted A3-coupling reaction of aliphatic and aromatic aldehydes with phenylacetylene and (R)-(+)-phenylethylamine is here reported. Two different synthetic methodologies have been investigated in this study, involving CuSO4/NaI and ­CeCl3·7H2O/CuI promoting systems. The reported methodologies were compared in terms of efficiency, diastereoselectivity, and toxicity, both showing advantages with respect to the current methodologies. The relative configurations of each of the obtained propargylamines, previously unknown in the literature, were assigned by comparison of the 1H NMR experimental chemical shifts with those theoretically predicted via the DFT-GIAO method.
Laboratory Results Release to Patients under the 21st Century Cures Act: The Eight Stakeholders Who Should Care
Authors: Arvisais-Anhalt Simone , Ratanawongsa Neda , Sadasivaiah Shobha 
Published: December 2022

AbstractA major aim of the 21st Century Cures Act is to support patients' access to their electronic health data and to prevent information blocking practices by health care organizations and health information technology developers. Prior to the Cures Act, significant variation existed in patient access to laboratory test results, key pieces of health data which enable timely self-management and engagement in care. Although many health care systems began releasing test results immediately through patient portals because of the Cures Act, implementation remains challenging due to variations in state regulations around electronic results release, local interpretations of allowable exceptions to Cures information blocking, concerns about privacy of sensitive laboratory results, and technological limitations. This paper outlines the eight stakeholder groups involved in implementation of electronic laboratory result release to patients and describes recommendations for these groups to consider in achieving the Cures Act goals to support a patient's access to their health information and control of their health care.
Impact of COVID-19 on Infants followed after Discharge from the Neonatal Intensive Care Unit Using a Telemedicine Model
Authors: Montoya-Williams Diana , Gualy Sebastián , Mazur Margaux , Huber Matthew , Peña Michelle-Marie , DeMauro Sara B. , Duncan Andrea F. 
Published: December 2022

Objective Coronavirus disease 2019 (COVID-19) continues to have a profound impact on infant health care and health outcomes. In this study, we aimed to characterize the social impact of the first COVID-19 lockdown on families in a neonatal follow-up program (NFP). Given the ongoing increased use of telehealth across the medicine, we also evaluated for patient-level differences in virtual visit rates to identify patients at risk of follow-up challenges.
Study Design To assess the impact of virtual health care utilization, we conducted a retrospective cohort study to describe challenges associated with telemedicine use in this vulnerable patient population during our telemedicine epoch (March 13, 2020–July 31, 2020). We also looked for patient-level factors associated with attending NFP visits as scheduled. Finally, we summarized caregiver responses to a COVID-19 Obstacles Assessment Survey and assessed for racial disparities in these responses.
Results When comparing patients who completed their virtual visit to those who did not, we found no differences by infants' sex, birth weight, gestational age at birth, or caregiver self-reported race and ethnicity. However, infants whose visits did not occur were more often discharged with equipment or covered by public insurance. Nine percent of families reported food insecurity.
Conclusion During the initial COVID-19 lockdown, families with infants discharged from a neonatal intensive care unit (NICU) faced significant obstacles caring for their infants and attending scheduled follow-up visits. Infants in families with lower socioeconomic status or with increased medical complexity faced increased challenges in attending virtual follow-up visits during this epoch. Given the ongoing reliance on telemedicine in health care and the need to better prepare for future epidemics/pandemics, this study offers critical information that can assist neonatal teams in bolstering transitions to home and creating stronger safety nets for their patients after discharge.

MarkeTrak—Tracking the Pulse of the Hearing Aid Market
Authors: Carr Kate , Kihm Jan 
Published: December 2022

AbstractThe MarkeTrak surveys conducted by the Hearing Industries Association have been looking at trends in the hearing industry since 1989. The latest survey, MarkeTrak 2022, reviews ongoing trends in hearing device adoption including PSAPs and implants, satisfaction with hearing aids and hearing professionals, and a look into insurance coverage and price considerations. These are discussed as they relate to the five key areas of the marketing mix: people, products, price, place, and perception. The key takeaways from this survey include: adoption has doubled in the past 25 years; more than 75% of hearing aid owners feel the hearing professional play an important role in their success with hearing aids; financial assistance has doubled since 1991 to 54%; and additional efforts are needed to educate consumers on the technology and benefits of hearing aids and early intervention.
The Financing of Hearing Care: What We Can Learn from MarkeTrak 2022
Authors: Windmill Ian M. 
Published: December 2022

AbstractThe “cost” of hearing aids has been a perceived key driver of the uptake, or lack thereof, of hearing aids. The MarkeTrak 2022 survey included questions that focused on the cost of the hearing test and amplification devices, out-of-pocket expenses, third-party coverage, and the perceived value of the devices. The hearing test itself was perceived as a barrier for some as the expense of the visit or the lack of third-party coverage was often cited as a reason for not following through on a recommendation to get a test. For those persons who received a hearing test, financial constraints were noted to be the most significant reason for not following through on a recommendation for a hearing aid, particularly for those over the age of 65 years. Higher income levels or some third-party coverage for devices was related to higher adoption rates. For persons who did choose to purchase amplification devices, financial considerations were not among the most important factors in reaching that decision. A clear majority of persons who made the decision to purchase amplification were satisfied with the out-of-pocket expenses associated with the purchase. The MarkeTrak 2022 Survey also included questions designed to assess the price sensitivity of individuals to various scenarios regarding the cost (e.g., $1000/pair, $2000/pair, or $4000/pair) or the amount of third-party coverage (e.g., $1000/pair, $2000/pair, or Total Cost). Results indicate increased amounts of third-party coverage were a bigger motivator than simply lowered cost. The MarkeTrak Survey indicates perceived cost factors continue to play a role in decisions to pursue hearing care and/or amplification devices.
Living in the era of codes: a reflection on China’s health code system
Authors: Yu Haiqing 
Published: December 2022

AbstractThis article offers a critical analysis of China’s health code system, a data-powered pandemic control and contact tracing system that supposedly subjects all individuals in the country to its panopticon control, a surveillance system that monitors and categorises the Chinese population into the healthy (green), the dubious (yellow), and the unhealthy (red). The article highlights the pretence of surveillance as care and the digital divide that normalises discrimination against the elderly and other digitally left-behind population. It also illustrates how, from policy making and technological design to user engagement, the health code system is implemented, optimised, and used in everyday life to meet the needs of the vulnerable population. The health code is better taken as a medium of adaptable and communicative process that can reset the relation between the system and the lifeworld. It is the process of interchange between the system and the lifeworld that deserves our critical attention.
Towards semiotically driven empirical studies of ballet as a communicative form
Authors: Maiorani Arianna , Bateman John A. , Liu Chun , Markhabayeva Dayana , Lock Russell , Zecca Massimiliano 
Published: December 2022

AbstractThis paper treats dance as a movement-based semiotic system, focusing on classical ballet as an example in order to show how dance can be made accessible to both detailed description and empirical investigation as a form of communication. The study contributes to a growing tradition of multidisciplinary research that looks at a variety of dance forms from the perspectives of linguistics, communication studies and social semiotics, drawing additionally on recent developments in the formal semantics of non-verbal semiotic systems and on empirical methods emerging within functional accounts of multimodality. The paper consequently develops a particular treatment of ballet that offers a principled means of linking the physical stream of movement, recorded using motion caption technology, and discourse interpretations, such as those that are typically narratively relevant in classical ballet but which may be found in other forms of dance as well. The paper sets out how this may then support further empirical research by importing well-defined methods and even specific questions from linguistics and related fields.
Relationship between households’ share of food expenditure and income across South African districts: a multilevel regression analysis
Authors: Mulamba Kabeya Clement 
Published: December 2022

AbstractThis paper investigates the relationship between household income and the share of food expenditure in South Africa using clustered household income and socio-economic data published in the National Dynamics Income Study. To achieve this objective and because of the clustered nature of the data, a multilevel linear model, in particular, the random intercept model, was employed as a suitable method of investigation. Fixed effect methods were also used to compare results. The results confirmed that the share of household food expenditure is inversely related to household income in a district. This finding is consistent with Engel’s law, such that an increase in household income is related to a decrease in the proportion allocated to food items by a typical household within a district. It was found that the relationship between household income and food expenditure does not vary across districts. The finding also pointed out that the district context matters because the district’s average household income significantly explains the share of food expenditure at the household level.
