Authors: Xu Richard Huan , Zhou Ling-ming , Wong Eliza Lai-yi , Wang Dong 
Published: December 2021

Objective: This study aimed to investigate the importance of providing Internet-based healthcare services based on the preference of a sample of medical students in China.Methods: An online best-worst scaling (BWS) survey with Case 1 design was conducted. Balanced independent block design generated 12 choice task profiles for each participant to answer. Descriptive analysis was used to describe the respondents' characteristics; Multinomial and mixed logit regression methods were used to investigate the importance of Internet-based services based on respondents' preferences.Results: A total of 1,296 students completed the online survey and rated “Clinical Service,” “Decision Aids,” and “Public health” as the three most important services that should be provided through an Internet-based healthcare system. Providing “Medical Education” via the Internet was chosen as the least important service by the respondents. Subgroup analysis indicated that students studying clinical medicine and non-clinical medicine considered providing “Medical Education” and “Public Health,” respectively, as more important services than others.Conclusions: This BWS study demonstrated that providing “Clinical Service,” “Decision Aids,” and “Public Health” through the Internet are the three most important services based on medical students' preferences in China. Further research is needed to investigate how to improve medical students' skills in using internet-based healthcare services in medical education programs.

Background: The objective of this study was to compare the incidence of severe systemic inflammatory response syndrome (sSIRS) after total aortic arch replacement between patients who underwent moderate hypothermic circulatory arrest (MHCA) and those who underwent deep hypothermic circulatory arrest (DHCA).Methods: At Fuwai Hospital, 600 patients who underwent total aortic arch replacement with MHCA or DHCA from January 2013 to December 2016 were consecutively enrolled and divided into DHCA (14.1–20.0°C) and MHCA (20.1–28.0°C) groups. Preliminary statistical analysis revealed that some baseline indicators differed between the two groups; therefore, propensity score matching (PSM) was used to balance the covariates. Post-operative sSIRS as the primary outcome was compared between the groups both before and after PSM.Results: A total of 275 (45.8%) patients underwent MHCA, and 325 (54.2%) patients underwent DHCA. After PSM analysis, a total of 191 matched pairs were obtained. The overall incidence of sSIRS was 27.3%. There was no significant difference in post-operative sSIRS between the MHCA group and the DHCA group in either the overall cohort or the PSM cohort (no-PSM: P = 0.188; PSM: P = 0.416); however, post-operative sSIRS was increased by ~4% in the DHCA group compared with the MHCA group in both the no-PSM and PSM cohorts (no-PSM: 29.5 vs. 24.7%; PSM: 29.3 vs. 25.1%). Both before and after PSM, the rates of gastrointestinal hemorrhage and pulmonary infection and post-operative length of stay were significantly increased in the DHCA group compared with the MHCA group (P &lt; 0.05), and the remaining secondary outcomes were not significantly different between the groups.Conclusions: MHCA and DHCA are associated with comparable incidences of sSIRS in patients following total aortic arch replacement for type A aortic dissection. However, the MHCA group had a shorter cardiopulmonary bypass time, a shorter post-operative length of stay and lower pulmonary infection and gastrointestinal hemorrhage rates than the DHCA group. We cautiously recommend the use of MHCA for most total arch replacements in patients with type A aortic dissection.

Published: December 2021

Relevance. Dental care is one of the principal unmet health needs of children with autism spectrum disorder (ASD). Based on the available publications, the study discusses the dental profile of a child with autism and the social factors affecting the oral health of such children.Materials and methods. A search was performed of publications for the 15 years in the Medline database using the terms autism”, behavior management/techniques”, child”, dental care for children with other abilities”, dental education”, dental disease”, pediatric dentistry” to find relevant publications.Results. In the found publications, the authors most frequently mention poor oral hygiene. However, they disagree regarding the caries occurrence rate in children with ASD. Insufficient specialized training of dentists on interaction with special children may be one of the reasons for the limited access to dental care.Conclusions. Dental treatment of an autistic child requires a thorough knowledge of comorbidity, relevant behavioral management and customization of treatment protocols according to individual needs. The effectiveness, safety and rationale of the known dental treatment strategies for children with ASD require further study and improvement.
The structure and prevalence of superficial carious and non-carious lesions of permanent and deciduous enamel in children who presented for routine dental care in various districts of St. Petersburg
Authors: Abramova N. E. , Silin A. V. 
Published: December 2021

Relevance. To increase the effectiveness of prevention and treatment protocols, it is above all necessary to consider the activity of caries, especially at the early enamel lesion stage, in the form of a white spot, to make the correct diagnosis based on a clinical examination, which assesses the location, change in surface hardness, symmetry, contour shape, depth, color and opacity of the lesion. Different causes of superficial enamel discoloration, in the form of white spots, are paramount for the restorative treatment as the quality of the enamel preparation affects the marginal fit and the durability of the restoration. However, poor oral hygiene, disturbance in eating behavior affect the course of non-carious hard-tissue diseases, which caries may complicate. Purpose – to optimize the diagnosis of initial dental enamel lesions to improve the caries prevention quality.Materials and methods. The study examined 460 children living in the Central and Krasnoselsky districts of St. Petersburg. The following indices assessed hard tissue condition: OHI-S, Greene and Vermillion; OHI by O'Leary T., Drake R., Naylor; White spot lesions index, Gorelick L, Geiger A. M, Gwinnett A. J., DMFT and df; caries activity.Results. The total prevalence of superficial (initial) lesions of hard tissues was 37.82%, i.e. 174 people out of 460 examined patients had superficial enamel lesions according to the criteria of I and II categories. The study found enamel changes in the age groups: 5-6 years (130) – 36 people (27.69%); 12 years old (175) – 62 people (35.42%); 15 years old (155) – 76 people (49.03%).Conclusions. Focusing on the caries activity signs rather than a precise differential diagnosis of the lesion nature is necessary to provide well-timed treatment and prevention upon detecting initial enamel lesion at a dental check-up.

Published: December 2021

The present study assessed the topical potential of nanofibers loaded with Mupirocin (MUP) for the treatment of burns. Nanofibers of MUP were composed of Polyvinyl Pyrrolidone (PVP), Gelatin Type-A, and Ethanol using two methods: Solvent casting and Electrospinning. Nanofibers were characterized for Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Drug Content Studies, in-vitro drug permeation, antibacterial and stability studies. The FT-IR studies showed that the Electrospinning technique had a very good mixing of MUP with the polymer. SEM studies showed that the morphology of electrospinning nanofibers had diameters in the range of 70.41 nm- 406.83 nm. The thermal decomposition studies of optimized Nanofiber (E.S.1) were performed by DSC and TGA study and it was found that the formulation had high stability in high-temperature environments. Permeation studies showed that E.S.1 had the highest percentage amount and controlled release of the drug (90 %) up to 8 has compared to other formulations. Nanofibers prepared through the Electrospinning technique showed better antibacterial activity against Staphylococcus aureus as compared to the Solvent casting nanofibers. This research suggested that MUP loaded nanofibers can be potentially used as a topical drug delivery system for the treatment of burns.
Geray Hanedanının Osmanlı Devleti Topraklarında Kalan Maddi İzleri
Authors: Kırımlı Hakan 
Published: December 2021

Üç buçuk asır boyunca Kırım Hanlığı’na hükümdar veren Geray hanedanı mensupları XVI. yüzyıldan itibaren Osmanlı Devleti topraklarında yerleşmeye başlamışlardır. O kadar ki, XVIII. yüzyılda bu geniş hanedanın Osmanlı topraklarında yaşayan mensuplarının sayısı Kırım’da kalanların çok üzerine çıkmıştır. 1783’te Kırım Hanlığı’nın Rusya tarafından ortadan kaldırılmasını müteakip, Kuzey Kafkasya’ya yerleşenler dışında Geray hanedanı mensuplarının büyük çoğunluğu Osmanlı Rumelisi’nde toplanmıştır.
Osmanlı topraklarında yaşayan Geraylar burada geçirdikleri yüzyıllar içinde orada doğmuş, ölmüş ve sayısız mimarî eserler inşa ettirmişlerdir. Bu makalemiz bu coğrafyada Geraylardan kalabilen eserlerin bir dökümünü vermeyi amaçlamaktadır. Eski Osmanlı topraklarında Geraylardan geride kalan maddi izlerin büyük çoğunluğu mezar taşları olup, diğerleri iki türbe, bir köprü, bir çeşme, iki konak ile hamam, saray ve savunma kulesi kalıntılarından oluşmaktadır. Bunlar bugünkü Türkiye, Bulgaristan ve Yunanistan arazilerine dağılmış durumdadır. Muhakkak ki, günümüze ulaşabilen bu eserler bir zamanlar mevcut olanların çok küçük bir kısmından ibarettir. Söz konusu maddi izlerin tamamına yakını gayet harap ve restorasyona muhtaç durumdadır. Bununla birlikte, bu hanedan mensuplarının kendi vatanları olan Kırım’daki maddi izlerinin maruz bulunduğu muazzam tahribat göz önüne alındığında eski Osmanlı topraklarında kalabilen bu nispeten az sayıdaki izlerinin ve onların muhafazasının tarihî açıdan çok büyük önemi haiz olduğu ortaya çıkmaktadır.
A New Absolute Proper Motion Determination of Leo I Using HST/WFPC2 Images and Gaia EDR3

Published: December 2021

Abstract
We measure the absolute proper motion of Leo I using a WFPC2/HST data set that spans up to 10 yr to date the longest time baseline utilized for this satellite. The measurement relies on ∼2300 Leo I stars located near the center of light of the galaxy; the correction to absolute proper motion is based on 174 Gaia EDR3 stars and 10 galaxies. Having generated highly precise, relative proper motions for all Gaia EDR3 stars in our WFPC2 field of study, our correction to the absolute EDR3 system does not rely on these Gaia stars being Leo I members. This new determination also benefits from a recently improved astrometric calibration of WFPC2. The resulting proper-motion value, (μ

Tracing the Milky Way’s Vestigial Nuclear Jet
Authors: Cecil Gerald , Wagner Alexander Y. , Bland-Hawthorn Joss , Bicknell Geoffrey V. , Mukherjee Dipanjan 
Published: December 2021

Abstract
MeerKAT radio continuum and XMM-Newton X-ray images have recently revealed a spectacular bipolar channel at the Galactic Center that spans several degrees (∼0.5 kpc). An intermittent jet likely formed this channel and is consistent with earlier evidence of a sustained, Seyfert-level outburst fueled by black hole accretion onto Sgr A* several Myr ago. Therefore, to trace a now weak jet that perhaps penetrated, deflected, and percolated along multiple paths through the interstellar medium, relevant interactions are identified and quantified in archival X-ray images, Hubble Space Telescope Paschen α images and Atacama Large Millimeter/submillimeter Array millimeter-wave spectra, and new SOAR telescope IR spectra. Hydrodynamical simulations are used to show how a nuclear jet can explain these structures and inflate the ROSAT/eROSITA X-ray and Fermi γ-ray bubbles that extend ± 75° from the Galactic plane. Thus, our Galactic outflow has features in common with energetic, jet-driven structures in the prototypical Seyfert galaxy NGC 1068.
RELICS: ICL Analysis of the z = 0.566 Merging Cluster WHL J013719.8–08284

Abstract
We present a pilot study of the intracluster light (ICL) in massive clusters using imaging of the z = 0.566 cluster of galaxies WHL J013719.8–08284 observed by the RELICS project with the Hubble Space Telescope. We measure the ICL fraction in four optical ACS/WFC filters (F435W, F475W, F606W, and F814W) and five infrared WFC3/IR bands (F105W, F110W, F125W, F140W, and F160W). The ICL maps are calculated using the free-of-a-priori-assumptions algorithm CICLE, and the cluster membership is estimated from photometric properties. We find optical ICL fractions that range between ∼6% and 19%, in nice agreement with the values found in previous works for merging clusters. We also observe an ICL fraction excess between 3800 Å and 4800 Å, previously identified as a signature of merging clusters at 0.18 < z < 0.55. This excess suggests the presence of an enhanced population of young/low-metallicity stars in the ICL. All indicators thus point to WHL J013719.8–08284 as a disturbed cluster with a significant amount of recently injected stars, bluer than the average stars hosted by the cluster members and likely stripped out from infalling galaxies during the current merging event. Infrared ICL fractions are ∼50% higher than optical ones, which could be signatures of an older and/or higher-metallicity ICL population that can be associated with the buildup of the brightest cluster galaxy, passive evolution of previously injected young stars, or preprocessing in infalling groups. Finally, investigating the photometry of the cluster members, we tentatively conclude that WHL J013719.8–08284 fulfills the expected conditions for a fossil system progenitor.

Abstract
The structure of a dwarf galaxy is an important probe of the effects of stellar feedback and environment. Using an unprecedented sample of 223 low-mass satellites from the ongoing Exploration of Local Volume Satellites survey, we explore the structures of dwarf satellites in the mass range 105.5 < M

V <−9 mag and surface brightness μ

< 26.5 mag arcsec−2 within at least ∼200 projected kpc of the hosts. For this sample, we find a median satellite luminosity of M

V
= −12.4 mag, median size of r

e
= 560 pc, median ellipticity of ϵ = 0.30, and median Sérsic index of n = 0.72. We separate the satellites into late- and early-type (29.6% and 70.4%, respectively). The mass–size relations are very similar between them within ∼5%, which indicates that the quenching and transformation of a late-type dwarf into an early-type one involves only very mild size evolution. Considering the distribution of apparent ellipticities, we infer the intrinsic shapes of the early- and late-type samples. Combining with literature samples, we find that both types of dwarfs are described roughly as oblate spheroids that get more spherical at fainter luminosities, but early-types are always rounder at fixed luminosity. Finally, we compare the LV satellites with dwarf samples from the cores of the Virgo and Fornax clusters. We find that the cluster satellites show similar scaling relations to the LV early-type dwarfs but are roughly 10% larger at fixed mass, which we interpret as being due to tidal heating in the cluster environments. The dwarf structure results presented here are a useful reference for simulations of dwarf galaxy formation and the transformation of dwarf irregulars into spheroidals.
