Cogrowth series for free products of finite groups
Authors: Bell Jason , Liu Haggai , Mishna Marni
Published: December 2022

Given a finitely generated group with generating set [Formula: see text], we study the cogrowth sequence, which is the number of words of length [Formula: see text] over the alphabet [Formula: see text] that are equal to the identity in the group. This is related to the probability of return for walks on the corresponding Cayley graph. Muller and Schupp proved the generating function of the sequence is algebraic when [Formula: see text] has a finite-index-free subgroup (using a result of Dunwoody). In this work, we make this result effective for free products of finite groups: we determine bounds for the degree and height of the minimal polynomial of the generating function, and determine the minimal polynomial explicitly for some families of free products. Using these results we are able to prove that a gap theorem holds: if [Formula: see text] is a finite symmetric generating set for a group [Formula: see text] and if [Formula: see text] denotes the number of words of length [Formula: see text] over the alphabet [Formula: see text] that are equal to [Formula: see text] then [Formula: see text] is either [Formula: see text], [Formula: see text] or at least [Formula: see text].
Linking number and folded ribbon unknots
Authors: Denne Elizabeth , Larsen Troy
Published: December 2022

We study Kauffman’s model of folded ribbon knots: knots made of a thin strip of paper folded flat in the plane. The folded ribbonlength is the length to width ratio of such a folded ribbon knot. The folded ribbon knot is also a framed knot, and the ribbon linking number is the linking number of the knot and one boundary component of the ribbon. We find the minimum folded ribbonlength for [Formula: see text]-stick unknots with ribbon linking numbers [Formula: see text] and [Formula: see text], and we prove that the minimum folded ribbonlength for [Formula: see text]-gons with obtuse interior angles is achieved when the [Formula: see text]-gon is regular. Among other results, we prove that the minimum folded ribbonlength of any folded ribbon unknot which is a topological annulus with ribbon linking number [Formula: see text] is bounded from above by [Formula: see text].
Categorizations of Limits of Grothendieck Groups over a Frobenius P-Category
Authors: Puig Lluis
Published: December 2022

In [Frobenius Categories Versus Brauer Blocks, Progress in Math., 274] and in [Ordinary Grothendieck groups of a Frobenius [Formula: see text]-category, Algebra Colloq. 18 (2011) 1–76], we consider suitable inverse limits of Grothendieck groups of categories of modules in characteristics [Formula: see text] and zero, obtained from a folded Frobenius [Formula: see text]-category[Formula: see text], which covers the case of the Frobenius[Formula: see text]-categories associated with blocks; moreover, in [Beyond a question of Markus Linckelmann, arxiv.org/abs/1507.04278] we show that a folded Frobenius [Formula: see text]-categoryis actually equivalent to the choice of a regular central [Formula: see text]-extension [Formula: see text] of [Formula: see text]. Here, taking advantage of the existence of a perfect [Formula: see text] -locality [Formula: see text], we exhibit those inverse limits as the true Grothendieck groups of the categories of [Formula: see text]-and [Formula: see text]-modules for a suitable [Formula: see text]-group [Formula: see text] associated to the [Formula: see text]-category [Formula: see text] obtained from [Formula: see text] and [Formula: see text]. It depends on a vanishing cohomology result, given with more generality in the Appendix.

Published: December 2022

Let [Formula: see text] be a ring with an automorphism [Formula: see text] of order two. We introduce the definition of [Formula: see text]-centrosymmetric matrices. Denote by [Formula: see text] the ring of all [Formula: see text] matrices over [Formula: see text], and by [Formula: see text] the set of all [Formula: see text]-centrosymmetric [Formula: see text] matrices over [Formula: see text] for any positive integer [Formula: see text]. We show that [Formula: see text] is a separable Frobenius extension. If [Formula: see text] is commutative, then [Formula: see text] is a cellular algebra over the invariant subring [Formula: see text] of [Formula: see text].

Let [Formula: see text] be a simplicial complex on [Formula: see text]. The [Formula: see text]-complex of [Formula: see text] is the simplicial complex [Formula: see text] on [Formula: see text] for which the facet ideal of [Formula: see text] is equal to the Stanley–Reisner ideal of [Formula: see text]. Furthermore, for each [Formula: see text], we introduce the [Formula: see text]th [Formula: see text]-complex [Formula: see text], which is inductively defined as [Formula: see text] by setting [Formula: see text]. One can set [Formula: see text]. The [Formula: see text]-number of [Formula: see text] is the smallest integer [Formula: see text] for which [Formula: see text]. In the present paper we are especially interested in the [Formula: see text]-number of a finite graph, which can be regraded as a simplicial complex of dimension one. It is shown that the [Formula: see text]-number of the finite graph [Formula: see text] on [Formula: see text], which is the disjoint union of the complete graphs [Formula: see text] on [Formula: see text] and [Formula: see text] on [Formula: see text] for [Formula: see text] and [Formula: see text] with [Formula: see text], is equal to [Formula: see text]. As a corollary, we find that the [Formula: see text]-number of the complete bipartite graph [Formula: see text] on [Formula: see text] is also equal to [Formula: see text].
1.3 μm broadband swept sources with enhanced nonlinear effects
Authors: Jiang Panqiu , Mu Jiale , Liu Yuxing , Wang Pinghe , Shi Guohua
Published: December 2022

In this work, a new structure is used to enhance the nonlinear effect in the cavity, which improves the performance of the 1.3[Formula: see text][Formula: see text]m broadband swept source. The swept source adopts a semiconductor optical amplifier (SOA), a circulator, a coupler, and a tunable filter. In the structure, the light passes through the nonlinear medium (SOA) twice in two opposite directions, which excites the nonlinear effect and increases the performance of the swept source. The tunable filter is based on a polygon rotating mirror and gratings. Traditionally, multiple SOAs are adopted to improve the sweep range and the optical power, which increases the cost and complexity of the swept source. The method proposed in this paper can improve the spectral range and optical power of the swept sources without additional accessories. For the short-cavity swept source, the power increases from 6[Formula: see text]mW to 7.7[Formula: see text]mW, and the sweep range increases from 98[Formula: see text]nm to 120[Formula: see text]nm. The broadband swept sources could have wide applications in biomedical imaging, sensor system, measurement and so on.
Reciprocal distance energy of complete multipartite graphs
Authors: Rakshith B. R. , Manjunatha B. J.
Published: December 2022

In this paper, first we compute the energy of a special partitioned matrix under some cases. As a consequence, we obtain the reciprocal distance energy of the complete multipartite graph and also we give various other energies of complete multipartite graphs. Next, we show that among all complete [Formula: see text]-partite graphs on [Formula: see text] vertices, the complete split graph [Formula: see text] has minimum reciprocal distance energy and the reciprocal distance energy is maximum for the Turan graph [Formula: see text]. At last, it is shown that the reciprocal distance energy of the complete bipartite graph [Formula: see text] decreases under deletion of an edge if [Formula: see text], and increases if [Formula: see text]. Also, we show that the reciprocal distance energy of the complete tripartite graph does not increase under edge deletion.
Biological Phenotyping in Sepsis and Acute Respiratory Distress Syndrome
Authors: Sinha Pratik , Meyer Nuala J. , Calfee Carolyn S.
Published: December 2022

Heterogeneity in sepsis and acute respiratory distress syndrome (ARDS) is increasingly being recognized as one of the principal barriers to finding efficacious targeted therapies. The advent of multiple high-throughput biological data (“omics”), coupled with the widespread access to increased computational power, has led to the emergence of phenotyping in critical care. Phenotyping aims to use a multitude of data to identify homogenous subgroups within an otherwise heterogenous population. Increasingly, phenotyping schemas are being applied to sepsis and ARDS to increase understanding of these clinical conditions and identify potential therapies. Here we present a selective review of the biological phenotyping schemas applied to sepsis and ARDS. Further, we outline some of the challenges involved in translating these conceptual findings to bedside clinical decision-making tools.
The Electrochemical Behavior of As-Prepared Aluminum Alloy A360 Produced by Selective Laser Melting Fabrication with and without a Trivalent Chromium Process Conversion Coating
Authors: Walton Jack W. , Rice Lucas , McFall-Boegeman Sarah , Swain Greg M.
Published: December 2022

We report herein on the electrochemical behavior and corrosion resistance of as-prepared aluminum alloy, A360 (AlSi10Mg), fabricated by additive manufacturing, with and without a trivalent chromium process conversion coating. Selective laser melting was the 3D printing process used for the alloy build. The corrosion suppression provided by the coating system was assessed through electrochemical measurements and accelerated degradation testing during a 14-day continuous neutral salt-spray exposure. The results indicate that the conversion coating can be formed by solution pretreating (degreasing and deoxidation) the alloy (X-Z plane perpendicular to the build plane) with its native surface roughness (as-prepared) followed by immersion for 10, 15 or 20 min in the coating bath. All three immersion times provide an equivalent level of corrosion protection to the alloy. The conversion coating suppresses both anodic and cathodic currents, increases the polarization resistance, and provides both anodic and cathodic corrosion protection to the as-prepared alloy. The conversion-coated specimens exhibit good stand-alone corrosion resistance during a 14-day neutral salt-spray exposure with corrosion intensity values (g/m2-year) ∼10x lower than values for the uncoated, as-prepared alloy specimens.

Published: December 2022

Background. Kikuchi’s disease with only extracervical lymphadenopathy is rare. Case Presentation. A 15-year-old male has presented with a fever lasting more than 1 week and right axillary lymphadenopathy. An axillary lymph node biopsy revealed coagulation necrosis, nuclear decay products, infiltration of histiocytes, and enlarged lymphocytes; he was diagnosed with Kikuchi’s disease. The only four adult patients with Kikuchi’s disease presenting without cervical lesions have been previously reported. Conclusion. This is the only pediatric case of Kikuchi’s disease presenting without cervical lymphadenopathy. Kikuchi’s disease should be included in the differential diagnosis even in cases of extracervical lymphadenopathy alone.

Study on Fluid Front Motion of Water, Nitrogen, and CO2 during Anisotropic Flow in Shale Reservoirs
Authors: Zhang Xiangxiang , Gu Kai , Liu Chengyu , Cao Yangbing , Wang J. G. , Gao Feng
Published: December 2022

The fluid front motion is an important phenomenon during anisotropic fluid flow in rock engineering. The pore pressure and mechanical responses may be significantly influenced and show an obvious difference near the moving fluid front. However, few studies have been conducted to investigate the front motion of different types of fluids during anisotropic fluid flow. In this work, a numerical model was proposed to detect the front motion of water, nitrogen, and CO2 in anisotropic shale reservoirs. The full coupling effects among mechanical deformation, fluid flow, and moving boundary in anisotropic porous media were considered in the model construction. The impacts of different fluid properties among water, nitrogen, and CO2 on the anisotropic fluid flow have been discussed. Then, the proposed model was applied to study the differences in front motion among different types of fluids in anisotropic shales. The impacts of permeability and mobility on fluid front motion were investigated. The theoretical equations for predicting the fluid front motion of different types of fluids were established by introducing corresponding correction coefficients to the previous formulas. The results showed that the model can well describe the anisotropic fluid permeation process. The fluid front motion increased with the increase of permeability and mobility. At the same permeability or mobility, the nitrogen front motion was the largest and the water front motion was the smallest. The difference in fluid front motion among water, nitrogen, and CO2 was caused by the difference of their viscosity and compressibility. The proposed formulas can fast and accurately predict the evolution of fluid front motion for different types of fluids.
An Unusual Inverted Talar Neck Fracture–Dislocation
Authors: Kokubun Brent , Refaat Motasem
Published: December 2022

Talar neck fractures occur on a continuum of injury severity. Hawkins classification, later modified by Canale, is the gold standard method of describing talar neck fractures by the degree of dislocation. It has proven to be clinically relevant in predicting risk of osteonecrosis. Despite its merits, talar neck fractures present on a wide spectrum of involvement of the body and neck, dislocation, and concomitant injuries, making every situation a challenge in treatment. We present a unique case of a talar neck fracture in which the talar dome had dislocated and inverted 180°, which is not described in the widely used Hawkins classification. We recommend urgent open reduction, low threshold for use of a transcalcaneal traction pin and dual incisions, and guarded prognosis of osteonecrosis and posttraumatic arthritis.

Published: December 2022

The nematode Onchocerca lupi is an emerging human pathogen. Though its life cycle is not well studied, it likely infects humans after a bite from a black fly vector, which in turn acquires infective microfilariae from an infected canid. These microfilariae mature into an infective larval stage within the fly. Among six reported cases in the United States, five involved children, and all occurred in the southwest. In this report, we present a case of O. lupi infection with cervical spine invasion in a healthy 10-year-old girl. She presented with five months of neurological symptoms from a rural and medically underserved area, highlighting a need for clinical vigilance in such settings for this emerging infectious threat in the American southwest.

Published: December 2022

Background: Cancer cases diagnosed each year are increasing, mainly because the population is ageing and, in part, due to early detection. This implies that there are more and more persons that receive medical anticancer therapies and that are interested in maintaining their quality of life. Many oncological treatments, including chemotherapy, immunotherapy, surgery, and radiotherapy, and combined therapy are associated with cutaneous toxicity and long-term side effects to different tissues and organs. This is particularly relevant when new therapies are used since these may cause new and unexpected side effects that may be short-lived but, in some cases, may become chronic or permanent. Patients often seek advice with their oncologists on what can be done and what cannot be done. Notably, many of the cutaneous side effects can be prevented or reduced by adequate interventions. Summary: The aim of this review is to highlight how oncological patients may benefit from a closer collaboration between specialists in different branches. We will focus on women with breast cancer since we think that they may derive a special benefit from this collaboration, but we will analyse other cancers in future papers. Key Messages: The working group was created to help the medical doctor in the prevention and management of all the adverse effects of the oncological treatments, supporting patients in this phase of their life, including nutritional assessment and dietary support.

Authors: Shi Haoting , Huang Jingxuan , Zhao Shi , Jin Yiwen , Cai Rong , Ran Jinjun
Published: December 2022

Introduction: The aim of this study was to determine the stage-specific incidence trend of hepatocellular carcinoma (HCC) among US adults. Methods: The age-adjusted incidence rate was extracted from Surveillance, Epidemiology, and End Results database for localized, regional, and distant HCC. Trend analyses were conducted in the overall population and stratified by demographic and sociodemographic variables. The annual percentage change (APC) in 2014–2019 was estimated to determine the stage-specific incidence trend. Results: Although the incidence of localized HCC significantly declined, the incidence for regional and distant HCC plateaued in 2014–2019 (APCs, 4.4% [95% CI, −0.2% to 9.3%] and −0.7% [95% CI, −1.8% to 0.5%], respectively) with age and race/ethnicity disparities. More pronounced increases for regional and distant HCC were observed among the elderly (APCs, 8.4% [95% CI, 4.8–12.2%] and 2.2% [95% CI, 1.7–2.7%] for regional and distant HCC, respectively), non-Hispanic white individuals (APCs, 4.0% [95% CI, 2.9–5.1%] and 1.5% [95% CI, 0.7–2.4%] for regional and distant HCC, respectively). Conclusions: Disparities in incidence trends may reflect the inequalities in access to primary health care. More efforts are still in great demand for the vulnerable population.

The purpose of this study is to determine varied responses on socio-demographic profile of couple DepEd teachers in the new normal in terms of age, highest educational attainment, school attainment, position, school designation, salary grade level, take-home pay, years in service, number of children, years of being married, family size and another source of income, exploring different lived experiences of couple DepEd teachers along childcare/dependent care, support from family, self – management, life expectations, life satisfactions, workplace support, workload, financial management, work expectations and work satisfactions and recommend a policy framework that can be suggested in responding to the work life balance of couple DepEd teachers in the new normal. This research is focused on the Province of Masbate, specifically in the municipality of Mandaon. Five couple teachers who are teaching in public schools were pre – selected. The study employed qualitative method of research, specifically phenomenological analysis to gather the lived experiences of five couple DepEd teachers. A descriptive phenomenological approach to inquiry revealed that socio-demographic profile of couple DepEd teachers in the new normal is varied but related with each other in terms of age, educational attainment, position, designation, salary grade level, take-home pay, years in the service, and years of being married. Lived experiences of couple DepEd teachers in the new standard can be divided into work (workplace support, workload, financial management, and work expectations) and life (childcare, support from family, self–management, life expectations, life satisfaction, and financial management). Work and life experiences are factors that affect the work life balance of couple DepEd teachers. The researcher recommends a policy rooted on work and life satisfaction which are needed as measures for a right work life balance in the new normal.
Factors Affecting Millennials' Perspective on Investment Decision Behavior during the Pandemic
Authors: Singh Amarjeet
Published: December 2022

Investor decision behavior in any pandemic, Covid-19 always goes through rationally. In reality or practically, the investment decisions made by millennials (generation Y) are not always rational. The sole purpose of the topic under study is to investigate a spectrum of millennial (generation Y) investors’ behavioral factors that affect investment decisions during a pandemic. This study adopted secondary sources for data collection. The secondary data is gathered through published research papers in peer-reviewed journals, scholarly journals, magazines, news, and books, as well as published data from the government. The major findings reveal that millennials (generation Y) financially deal with more confusion and disagreements when dealing with various patterns of informed conduct or behavior in contrast to other generations. Also, if taken a step further, the outcomes imply a much more important aspect regarding investors' behavior, financial investments, and economic growth: that they were all affected by the Covid-19 pandemic. It caused anxiety and uncertainty among players in the market. Behavioral factors and heuristics like the overconfidence and attitude effect, and herding factors are considered to have also influenced investors' decisions. Furthermore, the market behavior factors of price change, market information, past trend, customer preference, and underlying stock fundamentals have an impact on individual investor decision behavior.
Esboço de uma definição de tragédia à brasileira: Álbum de família, de Nelson Rodrigues, encontra o modernismo dos anos 1970
Authors: Borges Mariana Toledo
Published: December 2022

Este texto se propõe a examinar, através de leitura crítica e cerrada, três dramas brasileiros situados em dois momentos históricos de efervescência modernista – ambos ocorridos no Brasil durante o século XX – e que têm em comum a temática da família. A partir disso, objetivou-se mapear as singularidades do que seria uma tragédia à brasileira em comparação a outras formas dramáticas que se desenvolveram posteriormente em solo nacional. Os dramas são Álbum de família (1945), de Nelson Rodrigues, o eixo tonal da análise aqui proposta – dela partirá a tentativa de definir o drama trágico –, Em família (1970), de Oduvaldo Vianna Filho, e Hoje é dia de Rock (1971), de José Vicente.
O surrealismo envergonhado

Ainda que não tenha havido um movimento surrealista no Brasil, alguns modernistas se identificaram com a estética e alguns dos princípios norteadores deste movimento, como por exemplo o inconsciente, e realizaram trabalhos no campo da fotomontagem. Contudo, tais experiências foram ofuscadas, inicialmente pelo desejo de criar um imaginário nacional e, posteriormente, pelo espaço conquistado por obras de caráter mais construtivo.
Da oferta à recusa: sobre os desaparecimentos imaginários do Monumento às Bandeiras
Authors: Virava Thiago Gil de Oliveira
Published: December 2022

Este artigo discute aspectos dos discursos que acompanharam a proposição do projeto do Monumento às Bandeiras por Victor Brecheret, em 1920, e a inauguração da obra, em 1953, destacando dois pontos: por um lado, a percepção do monumento como oferta dos paulistas à nação brasileira; por outro, a cena de sua destruição, imaginada por Oswald de Andrade cerca de um ano depois da primeira apresentação do projeto. Partindo dessa discussão, investigo como a imaginação de sua destruição ou de seu desaparecimento se projeta novamente sobre o monumento desde os anos 1970, agora com a obra já concretizada, a partir tanto de trabalhos de artistas contemporâneos quanto de uma intervenção realizada diretamente sobre a escultura em 2013.

Published: December 2022

Os clubes de futebol, além de serem entidades responsáveis pela gestão da equipe, são também espaços de socialização, de criação de memórias, ritos e manifestações profundas de torcedores. No Brasil, no entanto, ainda não há consenso sobre o papel organizacional desempenhado por tais entidades. Desta maneira, o objetivo deste artigo é, a partir de reflexões teóricas pautadas nos conceitos de organização e instituição, apontar caminhos para uma possível taxonomia organizacional de tais entidades dentro da indústria do esporte.

Dada Meets Dixieland: Marcel Duchamp Explains Fountain
Authors: Bailey Bradley
Published: December 2022

In a 1953 recorded conversation with Harriet, Carroll, and Sidney Janis that was never published, Marcel Duchamp gave his earliest and most detailed description of the origin and submission of the readymade Fountain to the first exhibition of the Society of Independent Artists in 1917. In addition to featuring several notable revelations about the Fountain episode, the interview is also remarkable for the light it sheds on another nearly contemporary account of the story of Fountain, published in 1956 in the book Modern Art USA by the art and music historian Rudi Blesh. Passionate advocates for Ragtime and the Dixieland jazz revival, Blesh and Harriet Janis were frequent writing partners, publishing several music and art books, and together founded a record label to record traditional jazz artists. Through Harriet and Sidney Janis's extensive artworld connections, Blesh became a close associate of Duchamp, whose impact on Blesh's formulation of Modern Art USA has not been given adequate consideration by scholars. This article presents an analysis of both the Janis and Blesh accounts of Fountain, which together comprise the most comprehensive narrative description of this iconic work of art from Duchamp's perspective.
Facing Poland's “New Historical Politics”: A
Conversation with Jaroslaw Suchan
Authors: o.k. grupa
Published: December 2022

This conversation between Jarosław Suchan, director of Muzeum Sztuki in Łódź, Poland, from 2006 to 2022, and grupa o.k., the collaborative endeavor of Julian Myers and Joanna Szupinska, addresses the current political crisis in Poland under the rule of the ethnocentric right-wing populist party Law and Justice and its effects on art-institutions in that country. It addresses Suchan's innovative approach to the avant-gardes of the early twentieth century, which he sees as internationalist and emancipatory, and explores the circumstances of his dismissal by forces within the ultra-conservative government. It provides Suchan's parsing of disparate factions within the ruling party, his critical analysis of their aims to advance a whitewashed view of Polish history, his efforts to produce a counternarrative to this “new historical politics,” and his hopes and fears for a Polish cultural scene under right-wing populist direction.
5. A Challenge to International Neoclassicism
Authors: Evans Dorinda
Published: December 2022

Rimmer's major sculptural works, such as St. Stephen, Falling Gladiator, Dying Centaur, and Osirus (destroyed), were created for exhibition and in response to the international neoclassical movement. In different ways, they are actually critiques of the rage for neoclassicism. Much of what Rimmer was trying to do is conveyed in his teaching, and he used his exhibited art as an extension of this. He wanted an art based not on copying from antique casts or from life but, rather, on the artist's own imagination so that the work is self-expressive. The fact that the man in Falling Gladiator assumes an impossible position is an instance of his insistence on the imaginative. The St. Stephen and a cast of the Falling Gladiator were exhibited in Paris at the Salon des Refusés, where the Gladiator created a stir as it seemed, wrongly, to be a cast of a live person. Rimmer broke new ground in producing fragmented human figures with an antique reference, such as his Osiris, a classical-Greek-looking nude male without parts of his arms. They resembled the broken ancient sculpture of the present rather than of the revered past. Originally Osiris had the head of a hawk. As with his pictures, Rimmer also was unusual in frankly accepting and portraying abnormalities as in his Seated Man (Despair). The late Fighting Lions, showing a male and female in vicious combat is arguably an allegory of male dominance. As an original thinker, Rimmer, more than once, explored the problem of expressing the spiritual in the material, most effectively in his relatively abstract Torso, which is an attempt to show the divine awakening or creation of a human soul. Following the Bible, the plaster cast retains the effect of a man’s torso having been crudely fashioned from clay. Perhaps just as unexpected was his plan for a colossal sculpture, Tri Mountain (never executed), which amalgamated the effect of three men and three hills as a symbol of the city of Boston. His one major public statue is the over-life-size Alexander Hamilton on Commonwealth Mall in Boston.

Background

Acinetobacter calcoaceticus-A. baumannii (ACB) complex pathogens are known for their prevalence in nosocomial infections and extensive antimicrobial resistance (AMR) capabilities. While genomic studies worldwide have elucidated the genetic context of antibiotic resistance in major international clones (ICs) of clinical Acinetobacter spp., not much information is available from Bangladesh. In this study, we analysed the AMR profiles of 63 ACB complex strains collected from Dhaka, Bangladesh. Following this, we generated draft genomes of 15 of these strains to understand the prevalence and genomic environments of AMR, virulence and mobilization associated genes in different Acinetobacter clones.

Results

Around 84% (n = 53) of the strains were extensively drug resistant (XDR) with two showing pan-drug resistance. Draft genomes generated for 15 strains confirmed 14 to be A. baumannii while one was A. nosocomialis. Most A. baumannii genomes fell under three clonal complexes (CCs): the globally dominant CC1 and CC2, and CC10; one strain had a novel sequence type (ST). AMR phenotype-genotype agreement was observed and the genomes contained various beta-lactamase genes including blaOXA-23 (n = 12), blaOXA-66 (n = 6), and blaNDM-1 (n = 3). All genomes displayed roughly similar virulomes, however some virulence genes such as the Acinetobactin bauA and the type IV pilus gene pilA displayed high genetic variability. CC2 strains carried highest levels of plasmidic gene content and possessed conjugative elements carrying AMR genes, virulence factors and insertion sequences.

Conclusion

This study presents the first comparative genomic analysis of XDR clinical Acinetobacter spp. from Bangladesh. It highlights the prevalence of different classes of beta-lactamases, mobilome-derived heterogeneity in genetic architecture and virulence gene variability in prominent Acinetobacter clonal complexes in the country. The findings of this study would be valuable in understanding the genomic epidemiology of A. baumannii clones and their association with closely related pathogenic species like A. nosocomialis in Bangladesh.

Background

In 2020, almost 20% of people living with HIV (PLHIV) in Morocco are still unaware of their HIV status. Under these circumstances, HIV self-test (HIVST) can be an efficient additional tool for improving the testing rates in Morocco and reaching the first objective of the UNAIDS 95–95-95 goal. ALCS, a Community-based organization, involved in HIV Testing since 1992, and the Ministry of Health of Morocco conducted, a study on the acceptability and usability of HIVST among Female sex workers (FSW) and MSM (men who have sex with men), using a salivary rapid test. To our knowledge, this is the first study in Morocco exploring these parameters.

Methods

We conducted a pilot study on the usability of the OraQuick HIV-1/2 salivary self-test among MSM and FSW visiting the ALCS centers for standard HIV rapid testing in five Moroccan cities.

Participants chose whether or not to be assisted by lay provider HIV testing. The counselors sampled them to perform a standard rapid test and then invited them to a private room to perform the HIV self-test simultaneously. In addition, a questionnaire was administered to collect socio-demographic data and to assess their opinion about the usability of the salivary HIVST.

Results

Our study was carried out for 5 months and included 492 participants (257 MSM and 233 FSW). The average age of the participants was 29 years among MSM vs 34 years among FSW. The FSW have a lower educational level, 28,8% of them are Illiterate vs. 6,1% of the MSM.

Only 18% of participants were aware of the existence of the HIVST, nevertheless, we recorded a very high rate of acceptability (90,6%) of the HIVST. Performing the HIVST was deemed very easy for 92,2% of MSM versus 80,6% of FSW. Although it was found very difficult for six participants, including five FSW, 4 of them could not read or write. Overall, the study registered a high HIV positivity rate (3,8%) and 100% of concordance between HIVST participants’ interpretation and standard HIV testing performed by ALCS lay provider HIV testing.

Conclusion

Our study shows very high acceptability of HIVST among FSWs and MSM in Morocco, HIV self-testing is still unknown by key populations in Morocco, and the low level of education of FSWs may be a barrier to the use of this test, but with the proposed assistance and adapted demonstration tools, the HIV self-testing will certainly improve access to testing in Morocco.

Published: December 2022

Background

Data is inconsistent and, for the most part, not sufficient to demonstrate the association between serum Prolactin (PRL) concentration within the physiologic range and the incidence rate of type 2 Diabetes Mellitus (DM) among men. Moreover, since both PRL and type 2 DM are associated with reproductive hormones, investigating these hormones might improve our understanding of how PRL might impose its effect on the incidence rate of type 2 DM.

Methods

For the present study, 652 eligible men aged 29–70 with a normal baseline PRL concentration were selected from the Tehran Lipid and Glucose Study (TLGS). Participants were sub-classified into three groups (tertiles) according to the serum concentration of PRL and were followed for 15.8 years. The incidence of type 2 DM and PRL, LH, FSH, testosterone, and AMH concentrations were measured. The effect of hormonal variables on the incidence of type 2 DM was estimated using the log-binomial model, adjusted for major confounding factors. The correlations between PRL and the indicators of glucose and lipid metabolism and other hormonal variables were also explored.

Results

In the unadjusted model, PRL was not significantly associated with the incidence rate of type 2 DM (RR = 0.98, 95% CI: 0.94 − 1.03). After adjusting for potential confounders, the inverse effect of AMH on the incidence rate of type 2 DM was the only significant association. The analyses also indicated a significant positive association between PRL and LH/FSH ratio (r = 0.1,P = 0.01).

Conclusion

No significant association was found between serum PRL concentrations within the physiologic range and the incidence rate of type 2 diabetes mellitus among middle-aged men. Men with higher concentrations of PRL within the physiologic range tended to show higher levels of LH and LH/FSH. AMH was the only variable significantly linked to the incidence rate of type 2 DM in men.
Effects of a teaching mode combining SimBaby with standardized patients on medical students’ attitudes toward communication skills
Authors: Tian Ji-Dong , Wu Fei-Feng , Wen Chuan
Published: December 2022

Objective

To evaluate the effect of a teaching mode combining SimBaby with standardized patients (SP) on medical students’ attitudes toward communication skills (CS).

Methods

Forty 8-year medical program students majoring in clinical medicine were randomly divided into the SimBaby group (n = 20) and the SP + SimBaby group (n = 20). The Communication Skills Attitude Scale (CSAS) was used to evaluate medical students’ attitudes toward CS learning.

Results

In the SimBaby and SP + SimBaby groups, there were no statistically significant differences in the Positive Attitude Subscale (PAS) and Negative Attitude Subscale (NAS) scores between males and females (p > 0.05). Compared to the SimBaby group, the SP + SimBaby group showed statistically significant differences in PAS, NAS, and the two dimensions of importance in medical context and learning (p < 0.05). There were no statistically significant differences between groups in the dimensions of excusing and overconfidence (p > 0.05).

Conclusion

Compared with SimBaby alone, the SP + SimBaby teaching mode can improve medical students’ attitude toward CS learning, suggesting that the organic integration of multiple simulation-based medical teaching methods plays an important role in the acquisition of CS.

Published: December 2022

Background

The debate on whether or not there is a difference in the incidence of thyroid cancer between the patients with Solitary thyroid Nodule (STN) and Multinodular Goiter (MNG) has been constantly present for the last few decades. With newer studies yielding mixed results, it was imperative to systematically compile all available literature on the topic.

Methods

PubMed/MEDLINE, Cochrane Central, ScienceDirect, GoogleScholar, International Clinical Trials registry, and reference lists of the included articles were systematically searched for article retrieval. No filter was applied in terms of time, study design, language or country of publication. Rigorous screening as per PRISMA guidelines was undertaken by 2 independent reviewers in order to identify the articles that were most relevant to the topic.

Results

Twenty-two studies spanning from 1992 to 2018 were included in this analysis and encompassed 50,321 patients, 44.2% of which belonged to the STN subgroup and 55.37% to the MNG subgroup. MNG was found to be associated with a significantly lower risk of thyroid cancer (OR = 0.76; 95% CI 0.61–0.96) when compared with STN. Papillary carcinoma was the most frequently occurring carcinoma across both groups, followed by follicular and medullary carcinomas. A subgroup analysis was performed to assess the efficacy of the two most commonly employed diagnostic tools i.e. surgery and fine needle aspiration cytology (FNAC), however it yielded nonsignificant results, indicating a comparable usefulness of the two. Another subgroup analysis run on the basis of the presumed iodine status of the participants also yielded nonsignificant results.

Conclusion

There is a higher incidence of thyroid cancer among patients of STN, however, given the low quality of existing evidence on the topic, it is crucial to conduct larger studies that can establish association with a greater precision.
“…It just broke me…”: exploring the psychological impact of the COVID-19 pandemic on academics
Authors: Thompson Lynette , Christian Cindy
Published: December 2022

Background

The declaration of COVID-19 as a global pandemic by the World Health Organisation (WHO) in 2020 catapulted institutions of higher education into an emergency transition from face-to-face to online teaching. Given the nature of the COVID-19 pandemic and the continuing after-effects thereof, the study explored the psychological impact of the COVID-19 pandemic on academics.

Methods

A qualitative phenomenological research design was used to explore the psychological impact of the COVID-19 pandemic on academics. Data were collected by means of semi-structured interviews from a sample of 11 full-time academics permanently employed at six public and private higher education institutions in South Africa in 2020 and 2021. The data were analysed by means of thematic analysis.

Results

The study found that the COVID-19 pandemic and lockdown restrictions had a largely negative psychological impact on academics in higher education. The most dominant negative emotions reported by participants included stress, anxiety, fear and guilt either due to the threat of the virus itself, potential for loss of life, lockdown restrictions, a new working environment, and/or their perceived inability to assist their students. Participants also reported feelings of emotional isolation and an increase in levels of emotional fatigue.

Conclusion

In conclusion, institutions of higher education need to be aware of the negative psychological impact of COVID-19 on academics, and ensure they create and foster environments that promote mental well-being. Institutions may offer psychological services and/or emotional well-being initiatives to their academic staff. They must create spaces and cultures where academics feel comfortable to request and seek well-being opportunities. In addition to mental and emotional well-being initiatives, institutions must provide academics with tangible teaching and learning support as this would go a long way in reducing much of the stress experienced by academics during the pandemic.
