Paisagem com mulher e mar ao fundo: como esquecer os fluxos e refluxos das ondas?
Authors: De Carvalho Faria Ângela Beatriz
Published: May 2021

Partindo do princípio de que “a história e a arte ensinam que a revolta costuma nascer do luto e se propaga num turbilhão que mistura lamentos pessoais e coletivos, o próximo e o distante, numa extraordinária emoção coletiva”, Georges Didi-Huberman, filósofo e historiador da arte, no artigo “Ondas, torrentes e barricadas”, publicado na Revista Serrote do Instituto Moreira Salles, nos mostra como as sublevações ou insurreições políticas (“potências” ou “ondas”), de modo gradativo e imperceptível, tornam-se capazes de fazer erodir um poder constituído que se julgava inamovível (“barragens” ou “falésias”). E é exatamente isso que iremos encontrar em Paisagem com mulher e mar ao fundo, romance de Teolinda Gersão, uma das mais consagradas escritoras portuguesas contemporâneas, reeditado em 2019: a presença de uma revolta popular, em uma aldeia à beira-mar plantada, sitiada por Instituições e imagens-ícone do fascismo, na época do governo de António de Oliveira Salazar. O romance em questão, ao tematizar, metaforicamente, a Revolução de Abril de 1974, problematiza os conceitos de distopia e utopia, põe em cena “o circuito dos afetos, os corpos políticos e o desamparo”, o que, na ótica de Vladimir Safatle, promove “o fim do indivíduo”, circunscrevendo-o como um agente de transformação social.
Teaching Media in the Teaching of Arabic Language/ Media Pembelajaran dalam Pembelajaran Bahasa Arab
Authors: Gemilang Damar , Listiana Hastuti
Published: May 2021

This article discusses the media of learning Arabic language, through library studies that focus on distributing material effectively to students without making them boring. The limited creations and variations in learning as well as the low ability of Arabic language maharah of students make the role of the media so important. The selection of media correctly, can improve the mastery of material skills, motivate, and stimulate students. Through library studies from journals, papers, and books on learning media for the Arabic curriculum which are then analyzed and concluded data will be obtained about learning media for the Arabic curriculum which is useful for teachers. There are several rules in determining the media that will be used by taking into account the direction and objectives of learning, types of learning strategies, understanding the characteristics of the media by the teacher, in terms of cost suitability, media readiness, quality, and environment to operate the media. In terms of functions related to sensing devices, the media are divided into visual media, audio media, and audiovisual media. Meanwhile, viewed from the viewpoint in Arabic and that maharah, the media can be grouped into learning media mufrodat, nahwu-shorof, and Arabic language skills consisting of media istima', qiro'ah, kitabah, and kalam. This can help academics in applying media correctly in the learning of the Arabic language curriculum.One of the elements of learning Arabic is the student's Arabic learning strategy. But there are still some students who have not found the right strategy for learning Arabic, because of a lack of knowledge about Arabic learning strategies, especially the Oxford model of language learning strategies. The purpose of this study was to describe the implementation of the Arabic language learning strategy for students in the Oxford model of Madrasah Ibitidaiyah Al Islam Kartasura students.This research is descriptive qualitative, as for the research site at Madrasah Ibitidaiyah Al Islam Kartasura. This research was conducted from March to June 2020. The subjects in this study were students of class V A at Madrasah Ibitidaiyah Al Islam Kartasura. The informants in this study were the fifth grade Arabic teachers at Madrasah Ibitidaiyah Al Islam Kartasura. Data collection methods used were interviews, observation and documentation.The conclusion of this study is that students use Arabic learning strategies in the Oxford model because there are indications that students are using their learning. The strategies used are memory strategies, cognitive strategies, compensation strategies, metacognitive strategies, affective strategies, and social strategies. The strategy that is often used by students is the memorial strategy.
The relative contributions of slope gradient and vegetation cover on erosion characteristics of riparian slopes along the lower Yellow River, China
Authors: Cao Zihao , Zhao Qinghe , Ding Shengyan , Zhang Yifan
Published: May 2021

Slope gradient and vegetation cover play key roles in soil erosion
process. Exploring the effects of slope gradient and vegetation cover on
runoff and sediment yielding characteristics is therefore of great
importance for minimizing soil erosion. In this work, based on field
scouring experiments on the riparian slopes of the lower Yellow River,
China, variation in total runoff, accumulative runoff sediment
concentration, erosion sediment yield, and sediment particle size
composition under four slope gradients (5°, 10°, 15°, 20°) and three
vegetation cover levels (0%, 15%, 30%) were analyzed. Runoff and
sediment yield were greatly influenced by slope gradient at steep slope
gradients (15° and 20°), while they were mainly affected by vegetation
cover at medium slope gradients (5° and 10°). The main enriched particle
size of the eroded sediment showed a trend of first increasing and then
decreasing with the increasing slope gradient. There was an interaction
between slope gradient and vegetation cover, the effect of vegetation
cover on erosion sediment yield weakened gradually with increasing slope
gradient (at medium slope gradients of 5° and 10°), while the effect of
slope gradient increased at steep slope gradients (15° and 20°).
NSAIDs/Nitazoxanide/Azithromycin Repurposed for COVID-19: Potential Mitigation of the Cytokine Storm Interleukin-6 Amplifier via Immunomodulatory Effects
Authors: Kelleni Mina
Published: May 2021

Introduction

Mediators of immunity and inflammation are playing a crucial role in
COVID-19 pathogenesis and complications as demonstrated by several
genetic and clinical studies. Moreover, a weak, irregular, or inhibited
early interferon response to SARS CoV-2 infection was shown to trigger
an exaggerated inflammatory response leading to the COVID-19 associated
mortality. Thus, repurposing of drugs that possess anti-inflammatory
and/or immune-modulatory effects for COVID-19 is considered a rational
approach.

Areas covered

We present a concise analysis and interpretations of selected studies
that correlated COVID-19 with dysregulated interferon and inflammatory
responses while reflecting on our academic and real-life experience
using non-steroidal anti-inflammatory drugs, nitazoxanide and
azithromycin for management of COVID-19. Moreover, we interpret the
recent results that suggested a potential survival benefit of low dose
aspirin and colchicine when used for COVID-19.

Expert opinion

Nitazoxanide/azithromycin combination has been first hypothesized by the
author and practiced by him and several researchers to benefit COVID-19
patients due to a potential ability to augment the natural interferon
response as well as their positive immunomodulatory effects on several
cytokines. Furthermore, NSAIDs, that were unfortunately almost globally
avoided early in the COVID-19 era and still avoided in many developing
ones or at best of second choice in the developed ones, have been early
postulated and clinically practiced by the author to prevent or
ameliorate COVID-19 complications and mortality due to their ability to
prevent, constrain or reverse COVID-19 associated dysregulated immune
and hyper-inflammatory responses through mitigating the formation of
several inflammatory cytokines and pathways including the interleukin-6
amplifier and its NF-kB component, as well as modulation of a described
monocytic immunological dysrhythmia, which is also known to trigger the
COVID-19 cytokine storm. Finally, we repeat our previous call to adopt
our observational study that used these drugs in sufficiently powered
double blind randomized clinical trials as COVID-19 potential safe and
economic cure might be available and unfortunately repeatedly ignored
for one year.

Published: May 2021

The horizontal tracker is essential for the reliable operation of the Airborne Collision Avoidance System (ACAS). In ACAS target tracking, for the non-linear state estimation problem of using sensor measurement values to track in Cartesian coordinates, this paper proposes a horizontal tracking algorithm based on the Augmented Unscented Kalman Filter (AUKF) to achieve the horizontal of the target. Accurate tracking of direction. Firstly, the tracking model of the relative horizontal state of the target aircraft is established, and then the data is processed by AUKF. In order to verify the effectiveness of the horizontal tracking algorithm, the computer simulation method is used to simulate the track of the local aircraft and the intruder in the horizontal direction, and noise is added to the measured values. The traditional Kalman Filter In Polar Coordinates (KFPC) and AUKF algorithm are used to filter the ACAS horizontal tracking. The simulation results show that AUKF can achieve more accurate target tracking.

In the modern information society, high-precision clocks are particularly important in the fields of electric power, communications, aviation, and finance, and have very strict objective requirements in terms of frequency accuracy. Currently, the technology of using GPS satellite clock sources to synchronize local clocks has become one of the mainstream methods for generating high-precision clocks at home and abroad. The core idea of this technology is to use the satellite clock to tame the local clock. Due to the development and application of 5G, the accuracy of the system's punctuality have higher requirements, Through analysis, it is found that the combination of BP neural network and PID control can be used to optimize the control of the constant temperature crystal oscillator and improve the precision of punctuality. Finally, the simulation results show that the method has a significant effect in improving the accuracy of punctuality.
Proposed Treasury Regulations Address Tax Treatment of Modifications of Debt Instruments Made to Transition Away from LIBOR
Authors: Shipman Jamison K.
Published: May 2021

Trillions of dollars of debt instruments rely on the London Interbank Offered Rate (LIBOR) as a reference for establishing the interest rate payable on debt instruments. However, recent financial scandals and lack of a robust underlying market using LIBOR have resulted in the expectation that LIBOR will no longer be available after 2021. Thus, it will be necessary for such debt instruments to transition away from using LIBOR. Concerns have been raised regarding the potential tax implications resulting from alterations of debt instruments that transition away from LIBOR, including triggering a taxable event and application of the OID rules. This article highlights issues related to recently published proposed Treasury Regulations and provides recommendations for revisions to the proposed Treasury Regulations.
Adipose Tissue Insulin Resistance Is Longitudinally Associated With Adipose Tissue Dysfunction, Circulating Lipids, and Dysglycemia: The PROMISE Cohort

Published: May 2021

OBJECTIVE

To determine the association of adipose tissue insulin resistance with longitudinal changes in biomarkers of adipose tissue function, circulating lipids, and dysglycemia.

RESEARCH DESIGN AND METHODS

Adults at risk for type 2 diabetes in the Prospective Metabolism and Islet Cell Evaluation (PROMISE) cohort had up to four assessments over 9 years (n = 468). Adipose tissue insulin resistance was determined using a novel validated index, Adipo-IR, calculated as the product of fasting insulin and nonesterified fatty acids measured at baseline. Fasting serum was used to measure biomarkers of adipose tissue function (adiponectin and soluble CD163 [sCD163]), circulating lipids (total cholesterol, HDL, LDL, triglyceride [TG]), and systemic inflammation (interleukin-6 [IL-6] and tumor necrosis factor-α [TNF-α]). Incident dysglycemia was defined as the onset of impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes at follow-up. Generalized estimating equation (GEE) models were used to assess the relationship of Adipo-IR with longitudinal outcomes.

RESULTS

GEE analyses showed that elevated Adipo-IR was longitudinally associated with adipose tissue dysfunction (adiponectin −4.20% [95% CI −6.40 to −1.95]; sCD163 4.36% [1.73–7.06], HDL −3.87% [−5.15 to −2.57], TG 9.26% [5.01–13.69]). Adipo-IR was associated with increased risk of incident dysglycemia (odds ratio 1.59 [95% CI 1.09–2.31] per SD increase). Associations remained significant after adjustment for waist circumference and surrogate indices for insulin resistance. There were no significant longitudinal associations of Adipo-IR with IL-6, TNF-α, total cholesterol, or LDL.

CONCLUSIONS

Our findings demonstrate that adipose tissue insulin resistance is prospectively associated with adipose tissue function, HDL, TG, and incident dysglycemia.

Published: May 2021

OBJECTIVE

To identify risk factors for fracture in type 2 diabetes.

RESEARCH DESIGN AND METHODS

This prospective study included members of the Framingham Original and Offspring Cohorts. Type 2 diabetes was defined as fasting plasma glucose >125 mg/dL or use of type 2 diabetes therapy. We used repeated-measures Cox proportional hazards regression to calculate hazard ratios (HRs) and 95% CIs for associations between potential predictors and incidence of fragility fracture.

RESULTS

Participants included 793 individuals with type 2 diabetes. Mean ± SD age was 70 ± 10 years; 45% were women. A total of 106 incident fractures occurred over 1,437 observation follow-up intervals. Fracture incidence increased with age (adjusted HRs 1.00, 1.44 [95% CI 0.65, 3.16], and 2.40 [1.14, 5.04] for <60, 60–70, and >70 years, respectively; Ptrend = 0.02), female sex (2.23 [1.26, 3.95]), HbA1c (1.00, 2.10 [1.17, 3.75], and 1.29 [0.69, 2.41] for 4.45–6.46% [25–47 mmol/mol], 6.50–7.49% [48–58 mmol/mol], and 7.50–13.86% [58–128 mmol/mol]; Ptrend =0.03), falls in past year (1.00, 1.87 [0.82, 4.28], and 3.29 [1.34, 8.09] for no falls, one fall, and two or more falls; Ptrend =0.03), fracture history (2.05 [1.34, 3.12]), and lower grip strength (0.82 [0.69, 0.99] per 5-kg increase). Femoral neck bone mineral density, BMI, smoking, physical function, chronic diseases, medications, and physical function were not associated with fracture incidence.

CONCLUSIONS

Prior falls, fractures, low grip strength, and elevated HbA1c are risk factors for fractures in older adults with type 2 diabetes. Evaluation of these factors may improve opportunities for early intervention and reduce fractures in this high-risk group.

O Saber Urbano de Ermínia Maricato
Authors: Medeiros Wesley da Silva
Published: May 2021

EDITORIAL EM VIAS DE SER PUBLICADO
Este é o primeiro dossiê em homenagem à Erminia Maricato de outros três volumes a serem publicados em 2021 - volumes especiais. Ao longo deste texto, assumo a posição de intérprete, isto é, estou consciente do risco da análise ensaística, que vai propor interpretações sobre o pensamento dessa autora que instituiu o “Saber Urbano”, em que uma geração de pesquisadores da cidade aprendeu a ler para entender o fenômeno urbano brasileiro. De antemão, esse texto tem seu enraizamento no modo como o Antropólogo Clifford Geertz (1926; 2006) interpreta o pensamento de Claude Lévi-Strauss, Edward Evan Evans-Pritchard, Bronislaw Malinowski e Ruth Benediet. Mais ainda, como Peter Burke (2000) apreende o “Ofício do Saber” pela sociologia do conhecimento. Assim, buscarei situar a Erminia Intelectual e o Saber Urbano seu legado teórico e metodológico à pesquisa do tempo presente. Por isso, como intérprete, meu trabalho do pensamento encontra-se no campo do contingente, ou seja, posso ou não falar a mesma língua da Ermínia. Por isso, importa entender que sua obra pressupõe um tratado à pesquisa urbana, e assumo o papel de arqueólogo do seu conhecimento. Esclarecer essas questões iniciais permite aos leitores compreender meu lugar de fala - o interprete de um sistema de conceitos complexos, de uma autora que pensa pela pesquisa, escrita, militância, ativismo, o serviço público, docência, tornando-se uma cientista e intelectual do urbano.

Published: May 2021

Congestionamentos, acidentes de trânsito e poluição são alguns problemas resultantes de uma cultura de mobilidade que prioriza o transporte individual por meio do automóvel e o resultado dessa prioridade é a deteriorização da qualidade de vida urbana. De modo a tentar reverter esse panorama surge na UFPR o Programa de Extensão Universitária Ciclovida, acreditando que a Academia tem a obrigação de estar na vanguarda das transformações que a sociedade necessita, pois, através da pesquisa, ensino e extensão visa-se à formação de uma cultura de mobilidade urbana saudável e sustentável, pelo do uso da bicicleta como um dos meios de transporte. O objetivo deste artigo é demonstrar as contribuições da academia para a mobilidade urbana sustentável focando no Programa Ciclovida e a metodologia utilizada foi à pesquisa documental, sendo também uma pesquisa aplicada, qualitativa, exploratória, descritiva e bibliográfica. Dentre os resultados está à descrição do Programa e o Desafio Intermodal (anos de 2007 a 2013), demonstrando que a Academia pode sim, contribuir com a mobilidade urbana.

Authors: Mella Lisiane Ligia , Limberger Jéssica , Andretta Ilana
Published: May 2021

Políticas públicas voltadas ao adolescente em conflito com a lei têm sido amplamente destacadas ao longo da história brasileira, principalmente após o processo de redemocratização do país, que culminou na promulgação da Constituição Federal de 1988 e o posterior Estatuto da Criança e do Adolescente (ECA) em 1990. A presente revisão bibliográfica objetiva descrever estudos brasileiros de 2005 a 2015 acerca das políticas públicas dos adolescentes em conflito com a lei, analisando se tais estudos abordam a temática no contexto das pequenas e médias cidades. As bases de dados consultadas foram: Lilacs; Index Psicologia - Periódicos técnico-científicos e HISA - História da Saúde. Os artigos analisados evidenciam que a temática tem sido pouco abordada dentro do recorte temporal estabelecido. Todavia, alguns temas centrais aparecem, como: a necessidade de articulação das políticas públicas de cada cidade no atendimento ao adolescente em conflito com a lei; carência na integração das políticas para o efetivo funcionamento em rede; e a importância do trabalho interdisciplinar nas políticas públicas de cidades tanto pequenas e médias como em cidades grandes.Palavras-chave: Adolescente em conflito com a lei.

The purpose of the research is to establish a pattern for promoting the implementation of online education for students’ learning. The research methods are as follows: comparative analysis; regression analysis; systematization, generalization. As a result of regression analysis, it has been established that the value of the determination coefficient indicates that the regression model by 60% explains the dependence of online education in 30 countries between the results of students’ access to computers and the cost of education. It has been determined that a favorable climate for online education is formed in Denmark, Austria, Norway, Switzerland and Luxembourg. As a result of a students’ survey, it has been revealed that online education is better than traditional education (39%). However, some respondents believe that online education is inferior to university education (21%), and respondents said they would recommend online education. It has been found that obstacles in online education require immediate solutions, namely: ensuring uninterrupted Internet connection, reducing the process of social isolation, using video conferencing; it also requires the implementation of measures to ensure high-quality online education in educational institutions.

Desde los Sielungen hasta el S.A.A.L. La Ciudad Social como un continuum
Authors: Carvalho Ricardo
Published: May 2021

La cuestión de la ciudad periférica contemporánea ocupa un lugar central en el debate disciplinar sobre la forma urbana. No solo porque la ciudad periférica es cuantitativamente dominante en relación con la ciudad histórica, sino también porque concentra en sí misma la confluencia de varios modelos históricos. La vivienda fue elegida por diferentes movimientos europeos como instrumento para la reforma social. Este es el caso de la Ciudad Jardín (Garden City) o de los Siedlung, que convergerían, posteriormente, en las propuestas del Movimiento Moderno. Esta combinación, que permitió la asociación entre arquitectura y reforma social, estuvo presente en estos casos y en las operaciones del Servicio de Apoyo Ambulatorio Local, el S.A.A.L., que recuperó algunas estrategias urbanas y morfológicas defendiendo una intervención que formaba parte de un concepto amplio de ciudad. Este artículo aborda el tema de la vivienda social, en su formalización a nivel de barrio, a partir de un conjunto de ejemplos, construidos a lo largo del siglo XX, que se usan para explicar una posible visión de la Ciudad Social muy pertinente frente a una realidad contemporánea, relativa a la Vivienda colectiva, pobre en significado y frágil en términos de capacidad de respuesta.

Глобальный порядок и глобальное управление: практические вызовы и теоретические дебаты
Authors: Песцов С. К.
Published: May 2021

Современные дебаты о глобальном управлении и международном порядке отражают растущую обеспокоенность переменами, которые переживает современный мир. Данная работа, основываясь на предшествующих обсуждениях, предлагает модифицированный подход к содержательной дифференциации концептов «глобальный порядок» и «глобальное управление». Он исходит из очевидного отличия этих концептов по нескольким ключевым параметрам, включая (а) потребности и стимулы, лежащие в основе появления глобального порядка и вызывающих необходимость глобального управления; (б) характер действий, связанных с конструированием порядка и организацией управления; (в) результат этих дей-ствий; (г) состав акторов и их ролевые функции. Более чёткое смысловое разграничение концептов глобального порядка и глобального управления расширяет пространство обоснованных суждений относительно проблем, с которыми сталкивается мировое сообщество в ходе своего эволюционного развития. Благодаря этому появляется возможность более чёткого понимания того, свидетельствуют ли кризисные ситуации о непреодолимых дефектах сложившегося международного порядка в целом или же в большей степени отражают неспособность найти адекватные механизмы преодоления частичных возмущающих воздействий и появляющихся новых вызовов.

Effect of Monosaccharides and Disaccharides Type on Ionic Conductivity of Liquid Electrolyte Based Lithium Iodide
Authors: Ra'il Nur Hani , Mobarak Nadhratun Naiim
Published: May 2021

Liquid electrolyte was prepared by dissolving glucose, fructose, sucrose and lactose separately with different percentage of lithium iodide (10 â€“ 35%) in aqueous solution of 1% acetic acid. Liquid electrolyte is characterized using conductivity meter to determine ionic conductivity. Computer simulations of Density Functional Theory (DFT) was used to identify the dominant functional groups on monomers such as glucose, sucrose, fructose and lactose when interact with the lithium salt by using B3LYP/6-31G ++ (d, p) basis set. The highest ionic conductivity for monosaccharide is glucose at 28.20 mS/cm while for disaccharide is lactose at 28.00 mS/cm with percentage of salt at 35 wt.%. Ionic conductivity increases when concentration of salt increase because there is an interaction between salt with functional groups of compounds. Based on computer simulations of DFT, interaction between lithium with compounds can be occurred due to negative electrostatic potential on the molecule. Electronegativity value of oxygen atom in glucose (-0.562e) and lactose (-0.567e) higher than fructose (-0.559e) and sucrose (-0.515e). Functional groups that are dominant to interact when interact with lithium salt are O-15 for glucose and O-17 for lactose due to the shorter bond length, the stronger energy attraction between functional groups with lithium.

Published: May 2021

Structural changes in the retinal blood vessels provide important information about retinal diseases. Therefore, computer-aided segmentation of retinal blood vessels has become an active area of research in last decades. Due to the close contrast between the retinal blood vessels and the retinal background, robust methods should be developed to detect retinal blood vessels with high accuracy. In this work, artificial bee colony (ABC) algorithm which provides effective solutions to engineering problems has been applied to the retinal vessel segmentation. Clustering based ABC (basic ABC), quick-ABC (Q-ABC) and modified ABC (MR-ABC) algorithms have been analyzed for accurate segmentation of retinal blood vessels and their performances were compared. The simulations have been realized on the normal and abnormal retinal images taken from the DRIVE database. Simulation results and statistical analyses represent that ABC based approaches are stable and able to reach to optimal clustering performance with higher convergence rates. As a result it can be concluded that ABC based approaches can successfully be used for accurate segmentation of retinal blood vessels.
The Cultural Integration of Working Vietnamese People in Poland: An Analysis of Integration as the Process of Immigrants’ Lived Experience
Authors:   Faculty of Sociology andSocial Work, Hue University of Sciences, Hue University, Vietnam, Nguyen Huu An
Published: May 2021

This article is devoted to investigating the cultural integration of working Vietnamese immigrants in Poland. This study approaches cultural integration as a process of lived experience, paying particular attention to immigrants’ agency. The migrant group is viewed as active actors who are able to develop motivations for integration into their host culture or reinforce their loyalty to their original culture through interactions with new living settings in their country of residence. This study also examined the role of transnationalism in the process of cultural integration. Qualitative analyses showed that the motivations for cultural integration are strongly shaped by the immigrants’ impression of proper cultural standards and their admiration of the performance of social institutions, modernization, and living conditions in Poland. Motivations for integration played a crucial role in fostering the migrant group’s cultural acquisition. Concurrently, the migrant group exposed their disinclination to internalize cultural standards that challenged their established worldviews formed by socialization and education in the home country. This reluctance happens due to the role of transnational ties by which the migrant group can carry and practice their original culture. Consequently, transnationalism results in cultural resistance, hindering the cultural integration of the migrant group in Poland.

Peculiarities of main organisational forms of forensic activity have been analysed through special institutions (forensic science institutions) and through specific professionals: forensic experts (for example, practice of witness institution: professionals who took the oath or obtained a license for forensic examination conducting), international standards used in forensic science. The position of necessity of legislative introduction of international standards in conducting forensic examination is revealed and substantiated.
Connecting Structure and Variation in Sound Change
Authors: Natvig David , Salmons Joseph
Published: May 2021

“Structured heterogeneity”, a founding concept of variationist sociolinguistics, puts focus on the ordered social differentiation in language. We extend the notion of structured heterogeneity to formal phonological structure, i.e., representations based on contrasts, with implications for phonetic implementation. Phonology establishes parameters for what varies and how. Patterns of stability and variability with respect to a given feature’s relationship to representations allow us to ground variationist analysis in a framework that makes predictions about potential sound changes: more structure correlates to more stability; less structure corresponds to more variability. However, even though all change requires variability, not all variability leads to change. Two case studies illustrate this asymmetry, keeping a focus on phonetic change with phonological stability. First, Germanic rhotics (r-sounds) from prehistory to the present day are minimally specified. They show tremendous phonetic variability and change but phonological stability. Second, laryngeal contrasts (voicing or aspiration) vary and change in language contact. We track the accumulation of phonetic change in unspecified members of pairs of the type spelled
 ≠ , etc. This analysis makes predictions about the regularity of sound change, situating regularity in phonology and irregularity in phonetics and the lexicon. Structured heterogeneity involves the variation inherent within the system for various levels of phonetic and phonological representation. Phonological change, then, is about acquiring or learning different abstract representations based on heterogeneous and variable input.

Objetivo: Comparar o peso dos recém-nascidos de gestantes diabéticas gestacionais e metabolicamente normais.  Métodos: Trata-se de uma coorte histórica, onde foram estudadas pacientes atendidas nos serviços de Baixo e Alto Risco da Faculdade de Medicina da UFJF. Dados da anamnese, exame físico e conduta médica foram coletados, bem como os dados do recém-nascido. Resultados: Foram estudadas 133 pacientes, sendo 77 pacientes com diabetes gestacional (57,9%) e 56 (42,1%) metabolicamente normais. A média de peso do recém-nascido das pacientes do grupo controle foi de 3180 ± 545 g e das pacientes diabéticas foi de 3277 ± 439 g, mas sem significância estatística (p=0,361). A comparação entre a média de peso do recém-nascido em pacientes com diabetes em uso de insulina (3287 ± 350 g) e não usuárias de insulina (3178 ± 474 g) que também não foi significativa (p=0,448). Não houve associação entre o peso materno (peso inicial, peso final, ganho de peso) e peso do recém-nascido, avaliados através da regressão linear (p=0,448). Conclusão: O peso ao nascer foi semelhante em gestantes diabéticas gestacionais e gestantes normais, o que sugere que com o pré-natal eficiente alcança-se uma glicemia materna mais próxima da normalidade, fazendo diferença no prognóstico materno e fetal.

Published: May 2021

Background: Hidradenitis Suppurativa (HS) is a chronic condition that requires prompt diagnosis and treatment. To date, no bibliometric analysis on HS exists. Analyzing the top 100 citations is important to understand the characteristics of the most influential studies in the HS research landscape, and to guide future research.
Objective: To analyze the top 100 most cited articles on HS using bibliometric analysis.
Methods: Searches within Scopus and Web of Science using "Hidradenitis Suppurativa" and "Acne Inversa" were conducted on May 14th, 2020. After excluding non-original articles, data for the top 100 articles were analyzed using R-studio and Bibliometrix. Five independent reviewers identified study topic and design.
Results: The top 100 most cited articles on HS were published between 1982 and 2017 with an average of 128.3 citations. The top research topic and design were treatment (40 articles) and randomized controlled trials (9), respectively. 2011 had the highest number of publications (9), and the 2012 article by Gregor B. E. Jemec had the highest citations (439). These articles were from 14 different countries with the United States and Denmark as top countries. 27 journals published these articles with the British Journal of Dermatology (BJD) as the top journal. Denmark had the greatest outside country collaborations.
Conclusions: The results of our study showed that HS research is steadily growing with greatest support from the BJD. There is a focus on treatments in HS research with the United States and European countries leading the way. However, greater worldwide research of HS is needed.
Fillers for aesthetics on the face – Newer perspectives
Authors: Arora Gulhima
Published: May 2021

Dermal fillers are a cornerstone of the aesthetic treatments of the face. They have evolved over many aspects since their initial use. Facial fillers are not just used for anti-aging to restore volume, but are now also used for contouring, enhancing facial features, and changing the emotional attributes of the face. Newer techniques and approaches have been proposed for greater predictability of results and minimum complications. Newer composite filler materials and a resurgence of older materials have taken place with better understanding of the science behind them. With more use of facial fillers comes the reporting of newer complications with recommendations and guidelines to avoid them. A new perspective is seen in guidelines for their use in the COVID-19 pandemic. This article is a review of the insight into the latest perspectives of facial fillers for aesthetic indications.
Significance of cutaneous manifestations of COVID-19
Authors: M Malathi , Thappa Devinder Mohan
Published: May 2021

The COVID-19 pandemic has brought the whole world to a grinding halt. With the pandemic still ongoing, it is worthwhile to recapitulate the cutaneous manifestations for dermatologists, their significance, and spectrum of COVID-19 disease. COVID-19 is a highly contagious respiratory tract disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first reported on December 1, 2019, from Wuhan, China and was declared a pandemic by the World Health Organization on March 11, 2020. COVID-19 indirectly involves the skin just like any other viral infection and is independent of the disease stage or severity. Cutaneous manifestations of COVID-19 may present a few days before or after the first general symptoms of the disease. The appearance of cutaneous manifestations before early respiratory symptoms can promote early recognition of COVID-19 in such cases. The pathophysiology of cutaneous lesions in COVID-19 is still unclear. It is attributed to immune dysregulation, vasculitis, vessel thrombosis, neogenesis, hypercoagulable states, or simple hypersensitivity in COVID-19. Endothelial swelling with the presence of SARS-CoV-2 viral particles in the endothelial cells has also been seen on electron microscopy. Thus, the clinical features indicative of viral exanthems/enanthems which can be found in other diseases therefore fail to provide specific clues for diagnosis and prognosis of COVID-19. On the other hand, vasculopathy-related skin manifestations may provide prognostic values by indicating severe complications due to COVID-19 and may help in monitoring disease severity. Early detection of cutaneous signs associated with severe disease is crucial to improve patient outcomes.
Pericranial and scalp rotation flaps for occipitocervical hardware exposure with CSF leak in rheumatoid arthritis patient: A case report and review of the literature
Authors: Schonauer Claudio , Mastantuoni Ciro , de Divitiis Oreste , D’Andrea Francesco , de Falco Raffaele , Schonauer Fabrizio
Published: May 2021

Background:

There are several etiologies of craniocervical junction instability (CCJI); trauma, rheumatoid arthritis (RA), infections, tumors, congenital deformity, and degenerative processes. These conditions often require surgery and craniocervical fixation. In rare cases, breakdown of such CCJI fusions (i.e., due to cerebrospinal fluid [CSF] leaks, infection, and wound necrosis) may warrant the utilization of occipital periosteal rescue flaps and scalp rotation flaps to achieve adequate closure.

Case Description:

A 33-year-old female with RA, cranial settling, and high cervical cord compression underwent an occipitocervical instrumented C0–C3/C4 fusion. Two months later, revision surgery was required due to articular screws pull out, CSF leakage, and infection. At the second surgery, the patient required screws removal, the application of laminar clamps, and sealing the leak with fibrin glue. However, the CSF leak persisted, and the skin edges necrosed leaving the hardware exposed. The third surgery was performed in conjunction with a plastic surgeon. It included operative debridement and covering the instrumentation with a pericranial flap. The resulting cutaneous defect was then additionally reconstructed with a scalp rotation flap. Postoperatively, the patient adequately recovered without sequelae.

Conclusion:

A 33-year-old female undergoing an occipitocervical fusion developed a postoperative persistent CSF leak, infection, and wound necrosis. This complication warranted the assistance of plastic surgery to attain closure. This required an occipital periosteal rescue flap with an added scalp rotation flap.
Vascular entrapment neuropathy of the tibial nerve within the gastrocnemius muscle
Authors: Page Paul Samuel , Paige Stewart , Hanna Amgad
Published: May 2021

Background:

Vascular compression is an extremely rare cause of mononeuropathy and compression of selective tibial nerve branches is an additionally a rare finding and makes diagnosis difficult.

Case Description:

Here within, we describe the case of a 41-year-old male who presented with isolated mononeuropathy of the medial gastrocnemius (MG) branch of the tibial nerve presented as persistent fasciculations and atrophy. After electromyography and clinical evaluation, surgical exploration was recommended. A vascular bundle was found to be compressing the MG branch of the tibial nerve and thus was ligated to decompress the nerve. Postoperatively, all fasciculations improved and muscle atrophied improved.

Conclusion:

Vascular compression resulting in mononeuropathy of the peripheral nerves is a rare clinical entity. Clinicians should include these etiologies on their differential when considering surgical exploration of mononeuropathies.
