POLÍTICAS PÚBLICAS E PROTEÇÃO AOS IMIGRANTES VENEZUELANOS: UMA ANÁLISE A PARTIR DO CONCEITO DE BURDEN-SHARING
Authors: Passos Rute Oliveira , Lima Porto Matheus Macedo , Machado Jaborandy Clara Cardoso
Published: February 2021

Trata o presente estudo de uma análise de como as políticas migratórias brasileiras, especificamente o processo de interiorização realizado pelo governo federal tem se mostrado como medida eficaz para acolher os imigrantes venezuelanos que no último ano tem adentrado o território brasileiro solicitando refúgio. Objetiva-se com esse estudo observar como a cooperação entre estados da federação, mesmo que em obediência ao governo federal, se mostra como medida eficaz para equilibrar as responsabilidades do Estado nacional em relação ao acolhimento dos imigrantes. Especificamente, será analisado os fundamentos legais dessa política migratória, observando o contexto brasileiro em relação a imigração venezuelana e correlacionando a interiorização como processo de cooperação entre Estados, com moldes semelhantes ao que é colocado por Alexander Betts, como “burden-sharing”. Diante disso, compreende-se a necessidade de se observar as nuances das políticas de acolhimento aplicadas no Brasil, assim como também, elucidar seus pontos benéficos em relação a iminente “crise humanitária”. Para o desenvolvimento desse estudo, utilizou-se o método indutivo através de uma análise documental, exploratória e teórica da situação dos refugiados e da sua proteção nacional e internacional, correlacionando com o posicionamento do Estado brasileiro perante a situação dos imigrantes venezuelanos.
Pathological effects of ECHINOSTOMA PARAENSEI infection associated with pyogenic abscesses caused by PSEUDOMONAS AERUGINOSA in swiss mice
Authors: Silva Garcia Juberlan , Simões Raquel de Oliveira , Mota Ester , Soares dos Santos Incerlande , Maldonado Júnior Arnaldo
Published: February 2021

The trematode Echinostoma paraensei is an intestinal parasite transmitted by ingestion of the infectious stage of metacercariae. For scientific purposes, its life cycle has been maintained in the laboratory, allowing analysis using various biological approaches. Different parasite isolates have revealed atypical patterns of migration and establishment in ectopic sites in Swiss-Webster mice. During the investigation of the biological life cycle of an E. paraensei isolate from the silvatic rodent Nectomys squamipes collected in the municipality of Rio Bonito (State of Rio de Janeiro), a bacterial coinfection with Pseudomonas aeruginosa was observed, which produced anatomopathological alterations, mainly in the liver, bile ducts, pancreas, and small intestine. The main macroscopic signs were the whitish suppurative pyogenic punctual lesions. The histological sections stained by hematoxylin-eosin showed an intense inflammatory reaction formed by mononuclear cells and macrophages surrounding the bile ducts, although the hepatic parenchyma still presented its normal aspect. Thus, pyogenic abscesses can be associated with E. paraensei infection depending on the strain and aggravating pathogenesis in the definitive host.KEY WORDS: Liver abscess; Swiss mice; trematode infection.
Nationalism's Double-Bind: Individualism and the Global Implications of Milton's Nationalism
Authors: Stevens Paul
Published: February 2021

This essay argues that the emergence of the modern nation-state in the seventeenth century paradoxically produced or made possible the kind of individualism or sense of self, specifically the confidence in individual agency and human rights, on which globalism now seems to rest secure. Nowhere is this more apparent than in the work of Milton, a claim the article tries to illustrate with a comparison of the Treatise of Civil Power with The Readie and Easie Way.

Fertirrigação com Dejetos de Suínos: Uma análise de custos do Sistema Autopropelido x Sistema Tratorizado
Authors: Pellegrini Marcelo , Secchi Morgana , Tatim Denize Carvalho , Padilha Ana Claudia Machado , Três Eduardo Conterrato
Published: February 2021

Nos últimos anos, a atenção volta-se para as necessidades de desenvolvimento de tecnologias para a disposição de dejetos da suinocultura, uma vez que a atividade é caracterizada pela significativa carga de poluição e a criação está em constante expansão, uma vez que, a carne suína representa quase a metade do consumo e da produção mundial de carnes, sendo considerada a principal fonte de proteína animal. Dessa forma, o estudo tem como objetivo apresentar o funcionamento de um sistema de fertirrigação com dejetos de suínos em uma propriedade rural. Em termos metodológicos, foi realizada uma pesquisa de levantamento de custos, comparando o sistema de fertirrigação por tanque tratorizado com o sistema de fertirrigação autopropelido. Os dados do estudo revelam que a utilização dos dejetos como fertilizante revela-se como uma alternativa que se alinha à redução do impacto ambiental, especialmente por configurar-se como nutriente para as culturas produzidas em propriedades que têm acesso a este tipo de recurso de adubagem. Além do mais, foi possível identificar nas simulações de custo em uma área, que a fertirrigação se torna viável ao comparar o custo com o identificado no sistema tratorizado.
The Effects of Argumentation-Based Teaching on Primary School Students’ Academic Achievement, Science Attitudes and Argumentative Tendencies
Authors: Ateş Emrah , Özdemir Muhammet
Published: February 2021

This research aims to analyze the effects of argumentation-based teaching (ABT) on the 4th-grade students’ academic achievement, argumentative tendencies and attitude towards science. The universe of the research was 4th-grade students studying in Yığılca district of Düzce province in the 2017-2018 academic year, in Turkey. The sample of the research consists of 37 4th grade students studying in two different classes. The pretest-posttest matched control group design was used which is one of semi-experimental design techniques. While activities related to ABT were administered to the experimental group, the existing curriculum was applied for the control group. The data of the research were collected using three tools: science achievement test (AT), science attitude scale (SAS), and argumentativeness scale (AS). All data collection tools were administered to experiment and control groups as pre-test and post-test to determine if there was a difference after the application. The findings revealed that the academic achievement of the students was significantly influenced by the activities related to ABT. However, there was no significant difference between experimental and control groups in terms of argumentative tendencies and their attitude towards science.
Common Ingredients and Orographic Rain Index (ORI) for Heavy Precipitation Associated with Tropical Cyclones Passing Over the Appalachian Mountains
Authors: Rostom Riem , Lin Yuh-Lang
Published: February 2021

Relative contributions of common ingredients to heavy orographic rainfall associated with the passage of Hurricanes Hugo (1989) and Isabel (2003) over the Appalachian Mountains are examined using a numerical weather prediction model. It is found that the key ingredients for producing local heavy orographic rainfall were: high precipitation efficiency, strong low-level flow, strong orographically forced upward motion associated with strong low-level flow over relatively gentle upslope, concave geometry providing local areas of convergence, high moist flow upstream, a relatively large convective system associated with both tropical cyclones (TCs), and relatively slower movement. In addition, neither conditional instability nor potential (convective) instability is found to play essential roles in producing strong upward motion leading to heavy orographic TC rain. A modified Orographic Rain Index (ORI) is proposed as a predictor for heavy orographic TC precipitation, which includes the upstream incoming horizontal wind speed normal to the local orography, the steepness of the mountain, the relative humidity, the TC moving speed, and the horizontal scale of the TC. It is found that the ORI estimated in regions of local maximum rainfall by using fine-resolution numerically simulated results correlate well with rainfall rates for both hurricanes, indicating that it may serve as a predictor for heavy orographic TC rainfall.
Time and Cost Efficiency of Autonomous Vehicles in the Last-Mile Delivery: A UK Case
Authors: Feng Xuan
Published: February 2021

In recent years, last-mile delivery has become an increasingly important area in the global supply chain. Practically, there has been an increasing worldwide interest in developing the last-mile delivery robots/vehicles to increase the efficiency of the whole supply chain. Theoretically, several researchers have suggested that using autonomous robots brings more efficiency for delivery. However, almost no current studies consider a specific last-mile delivery activity – transport from supermarkets after loading to pick-up stations before unloading. The goal of this study is to investigate whether and how autonomous vehicles/robots can address the issue of cost and time efficiency. Specifically, this research aims at identifying the time and cost structures of using autonomous vehicles for the delivery along the chosen route – a single way from the Sainsbury’s supermarket to the Amazon pick-up station at Coventry. Furthermore, the research aims to find whether using autonomous vehicles is more efficient in time and/or cost than using vans with drivers for this route.
Equations for calculating ideal body weight in patients on mechanical ventilation in adult intensive care units in Latin America: exploratory review
Authors: Payán Salcedo Harold Andrés , Estela Zape José Luis , Wilches-Luna Esther C.
Published: February 2021

Introduction: Ideal body weight calculation is used in critical medicine for drug dosing and setting ventilation parameters. However, the suggested and used equations were designed on the basis of anthropometric variables that do not represent the Latin American population.
Objective: To map and present the current evidence on the equations used to calculate ideal weight in patients on mechanical ventilation in intensive care units in Latin America.
Material and Methods: Exploratory review using the Joanna Briggs Institute method conceived by Arskey / O’Malley. A search was performed in the BVS, LILLACS, REDALYC, Ovid, Google Scholar and Scielo databases using keywords and MeSH terms in Spanish, English, and Portuguese, with no time limitation. The results are presented in descriptive tables.
Results: Overall, 1126 studies were identified and 1120 were excluded; 6 studies were reviewed and 3 additional studies were identified through a manual search. The studies were published in Chile, Brazil, Mexico, Ecuador, and Peru. In 89%, the ARDS Network equation was used to calculate tidal volume. Acute respiratory distress syndrome was the most reported pathology (33%).
Conclusions: Adult intensive care units in Latin America use the equation suggested by the ARDS Network, which was designed in a population with different anthropometric characteristics.

Authors: Gaviria García Verónica , Loaiza López Daniel , Serna Rojas Carolina , Ríos Arismendy Sara , Montoya Guevara Eduardo , Mora Lesmes Juan Daniel , Gómez Oquendo Francisco Javier , Ochoa Gómez John Fredy
Published: February 2021

Introduction: The analysis of the electrical activity of the brain using scalp electrodes with electroencephalography (EEG) could reveal the depth of anesthesia of a patient during surgery. However, conventional EEG equipment, due to its price and size, are not a practical option for the operating room and the commercial units used in surgery do not provide access to the electrical activity. The availability of low-cost portable technologies could provide for further research on the brain activity under general anesthesia and facilitate our quest for new markers of depth of anesthesia.
Objective: To assess the capabilities of a portable EEG technology to capture brain rhythms associated with the state of consciousness and the general anesthesia status of surgical patients anesthetized with propofol.
Methods: Observational, cross-sectional trial that reviewed 10 EEG recordings captured using OpenBCI portable low-cost technology, in female patients undergoing general anesthesia with propofol. The signal from the frontal electrodes was analyzed with spectral analysis and the results were compared against the reports in the literature.
Results: The signal captured with frontal electrodes, particularly α rhythm, enabled the distinction between resting with eyes closed and with eyes opened in a conscious state, and sustained anesthesia during surgery.
Conclusions: It is possible to differentiate a resting state from sustained anesthesia, replicating previous findings with conventional technologies. These results pave the way to the use of portable technologies such as the OpenBCI tool, to explore the brain dynamics during anesthesia.
Prácticas de vigilancia en la política asistencial ¿Vigilar para proteger?
Authors: Vecinday Garrido Laura
Published: February 2021

Propongo introducirnos en los debates sobre el papel de los sistemas de información y la vigilancia poblacional en un sector particular de la política social, aquella dirigida a los sectores pobres, conocida comúnmente como política asistencial o socioasistencial. Específicamente, exploro las prácticas de vigilancia asociadas a la reciente reorganización de la política socioasistencial promovida por el Ministerio de Desarrollo Social (MIDES) de Uruguay. El objetivo es examinar las prácticas de vigilancia destinadas a controlar, rastrear, clasificar, comprobar y observar sistemáticamente a las poblaciones. Dos dimensiones ordenan el análisis de los sistemas de información para la protección social: el proceso de reforma del Estado como una de las condiciones sociohistóricas que contribuye a comprender la proliferación de estos sistemas y sus efectos esperados y colaterales en el entendido de que éstos últimos han sido invisibilizados en la reflexión vernácula sobre el tema.
Rapid reviews: definitions and uses
Authors: Tapia-Benavente Luis , Vergara-Merino Laura , Ignacio Garegnani Luis , Ortiz-Muñoz Luis , Loézar Hernández Cristóbal , Vargas-Peirano Manuel
Published: February 2021

This article is the first in a collaborative methodological series of narrative reviews on biostatistics and clinical epidemiology. This review aims to present rapid reviews, compare them with systematic reviews, and mention how they can be used. Rapid reviews use a methodology like systematic reviews, but through shortcuts applied, they can attain answers in less than six months and with fewer resources. Decision-makers use them in both America and Europe. There is no consensus on which shortcuts have the least impact on the reliability of conclusions, so rapid reviews are heterogeneous. Users of rapid reviews should identify these shortcuts in the methodology and be cautious when interpreting the conclusions, although they generally reach answers concordant with those obtained through a formal systematic review. The principal value of rapid reviews is to respond to health decision-makers’ needs when the context demands answers in limited time frames.
Epidemiological behavior of COVID-19 in the early phase of the pandemic in Cuba
Authors: Parra Linares Edwar , Lanio Posada Carlos Antonio
Published: February 2021

COVID-19 to date has caused hundreds of thousands of deaths in the world, becoming one of the worst pandemics in history. It all started in the People's Republic of China and quickly spread to the rest of the world. In this article, we seek to characterize the epidemiological situation of COVID-19 in Cuba during the first 80 days. For this article, we used observation and both quantitative and qualitative methods to collect data. We relied on statistical methodologies to validate the research. The study covered the days between March 11 and May 29, 2020. We analyzed the daily reports published by the Cuban Ministry of Public Health, this ministry's official website, and Cubadebate. Until May 29, the fifteen provinces of our country and the special municipality of Isla de la Juventud had confirmed positive cases, while the epicenter of the epidemic was the province of Havana. The coronavirus pandemic is a considerable challenge for the whole of Cuban society. A free health system, an inclusive social regime, and extensive experience in fine-tuning policies were some of Cuba's main strengths in facing the negative impact of the COVID-19 pandemic.

Authors: Darim Lucas Pasquali , Guridi Veronica Marcela , Amado Beatriz Crittelli
Published: February 2021

O ensino de Ciências tomou um caráter visual como resultado de um processo histórico. Para a compreensão dessa área do conhecimento, concedeu-se uma importância significativa para o sentido da visão. Atrelando esse fato à perspectiva da Educação Inclusiva apontada em documentos nacionais e internacionais, a presente revisão bibliográfica objetivou investigar trabalhos publicados em periódicos científicos entre 2000 e 2019 que descrevem e discutem práticas de ensino de Ciências da Natureza voltadas a estudantes com deficiência visual em contextos formais e não formais de ensino no Brasil (exceto espaços museais). As bases de dados consultadas foram SciELO, Sistema Integrado de Bibliotecas da Universidade de São Paulo (SiBi USP) e Google Acadêmico, buscando artigos publicados que tratassem a temática em questão a partir de práticas descritas e analisadas. A busca se deu por palavras-chave: Ensino de ciências and Deficiência Visual and Sequências didáticas; Ensino de Ciências and Deficiência Visual; Ensino de Ciências and Deficiência Visual and Recursos Didáticos. Com base em determinados critérios, foram selecionados e analisados 12 trabalhos. Os resultados mostram que, apesar da não referência direta, os trabalhos trazem o princípio da multissensorialidade, que pensa o ensino e aprendizagem de ciências a partir de todos os sentidos humanos, sendo adequado para pessoas com e sem deficiência. Práticas sob essa perspectiva mostraram-se eficientes alcançando estudantes com e sem deficiência visual através de um processo de desenvolvimento que ultrapassa a apropriação conceitual e atinge a transformação de atitudes dos estudantes especialmente na relação entre o educando enxergante e seu colega com deficiência visual.

Authors: Pawar Ankush , Sonika Ujjwal , Kumar Manish , Saluja Sundeep , Srivastava Siddharth
Published: February 2021

Background/Aims: The management of walled-off necrosis (WON) has undergone a paradigm shift from surgical to nonsurgical modalities. Real-world data on the management of symptomatic WON are scarce.Methods: Prospectively collected data of symptomatic WON cases were retrospectively evaluated. The treatment modalities used were medical management alone, percutaneous catheter drainage (PCD) or endoscopic drainage (ED), or a combination of PCD and ED. We compared clinical outcome among these modalities.Results: A total of 264 patients were evaluated. The most common indications for drainage were pain and fever. Of the patients, 28% was treated with medical therapy alone, 31% with ED, 37% with PCD, and 4% with a combined approach. Technical success and clinical success were achieved in 93% and 91% of patients in the endoscopic arm and in 90% and 81% patients in the PCD arm, respectively (p==0.0004 for clinical success). Lower rates of complications (7% vs. 22%, p==0.005), readmission (20% vs. 34%, p==0.04), and mortality (4% vs. 19%, p==0.0012), and shorter hospital stay (13 days vs. 19 days, p==0.0018) were observed in the endoscopic group than in the PCD group.Conclusions: ED of WON is better than PCD and is associated with lower mortality, fewer complications, and shorter hospitalization.
El bailarín y su configuración como categoría en una obra de danza
Authors: Ollora-Triana Natalia , Corbí Miguel
Published: February 2021

El presente artículo analiza las categorías que definen el bailarín como principal elemento de significación o signo para la construcción de la semiótica de la danza partiendo de la revisión documental. Dentro de un paradigma plural que integra el análisis cualitativo y la investigación basada en el arte, y desde la metodología observacional elaboramos un instrumento de análisis ad hoc con el objetivo de estudiar la relación entre movimiento y espacio y el carácter generador de significado dentro del proceso de comunicación. Entre los resultados más destacados resaltamos categorizar los signos que delimitan este elemento a modo descriptivo y de herramienta de análisis. Estos permiten concluir cómo, de manera principal pero no única, este elemento y la organización o conformación de sus signos, generan significado dentro del discurso de las obras de danza y son una aportación a su semiótica como un conjunto de elementos de creación con significado.

« À pas de loup » : incidences narratives de la pensée différée dans les séminaires de Jacques Derrida
Authors: Cotton Nicholas
Published: February 2021

Dans Trois ans avec Derrida, le biographe Benoît Peeters notait que le séminaire de Jacques Derrida était construit « comme un feuilleton théorique qui, par-delà les longueurs et les passages à vide, entretient une sorte de suspense et ménage de réelles surprises d’une séance à l’autre » (Peeters, 2010). Peut-on vraiment rapprocher un séminaire d’une forme romanesque comme le récit différé ? Voilà la question qui nous occupe dans cet article, et nous l’abordons dans une perspective double : à la fois historique et formelle. Nous nous interrogerons ainsi sur ce qu’est un séminaire et comment, dans le cas particulier du séminaire derridien, il fait oeuvre. Le tout nous mène à une réflexion sur l’idée de « pensée différée » à partir du concept central de différance dans l’enseignement derridien.
Pas de course. Notes piquées sur le séminaire « GREPH. Le concept de l’idéologie chez les idéologues français » (1974-1975)
Authors: Mercier Thomas Clément
Published: February 2021

Afin d’examiner la forme et la fonction « cours » dans le corpus de Derrida, je propose une lecture du séminaire inédit « GREPH. Le concept de l’idéologie chez les idéologues français » (1974-1975). Ce séminaire fut mené dans le cadre des engagements politico-institutionnels du GREPH (Groupe de recherches sur l’enseignement philosophique). Il constitue donc un point d’entrée privilégié pour saisir le rapport complexe que Derrida entretient avec l’enseignement, et plus généralement avec l’institution philosophique. Au cours de ce séminaire, Derrida s’intéresse au « corps enseignant » en tant qu’il fonctionne comme « machine reproductrice » au sein de l’organisation économique générale de la société. Courant deux lièvres à la fois, Derrida mêle une réflexion généalogique sur l’histoire de l’enseignement philosophique en France et en Europe à une analyse théorique de concepts marxistes et sociologiques tels que « capital », « reproduction », ou « appareil idéologique ». À travers des lectures déconstructrices et transformatrices de Marx et d’Althusser, Derrida s’efforce de penser une autre économie — une économie du texte débordant la logique reproductrice qu’il identifie aussi bien chez les économistes classiques que chez leurs critiques marxistes.

Beyond the Creative Species
Authors: Bown Oliver
Published: February 2021

A multidisciplinary introduction to the field of computational creativity, analyzing the impact of advanced generative technologies on art and music.

As algorithms get smarter, what role will computers play in the creation of music, art, and other cultural artifacts? Will they be able to create such things from the ground up, and will such creations be meaningful? In Beyond the Creative Species, Oliver Bown offers a multidisciplinary examination of computational creativity, analyzing the impact of advanced generative technologies on art and music. Drawing on a wide range of disciplines, including artificial intelligence and machine learning, design, social theory, the psychology of creativity, and creative practice research, Bown argues that to understand computational creativity, we must not only consider what computationally creative algorithms actually do, but also examine creative artistic activity itself.

After describing the state of the art in computational creativity—including past and present cycles of hype—Bown examines the psychology of creativity and how it may be amenable to algorithmic automation. He considers human creativity as a social phenomenon that depends on such factors as position within a social network and group identity. He reviews the existing algorithms for the production of computer-generated content, examines issues of interaction design, and explores paradigms of computational creativity; considers the evaluation of computationally creative systems, addressing the difference between the analysis of systems as creative agents and as creativity support tools; and, looking to the future, discusses the social implications of the consumption and experience of generated art and music.
Physically asymmetric division of the C. elegans zygote ensures invariably successful embryogenesis
Authors: Jankele Radek , Jelier Rob , Gönczy Pierre
Published: February 2021

Asymmetric divisions that yield daughter cells of different sizes are frequent during early embryogenesis, but the importance of such a physical difference for successful development remains poorly understood. Here, we investigated this question using the first division ofCaenorhabditis elegansembryos, which yields a large AB cell and a small P1cell. We equalized AB and P1sizes using acute genetic inactivation or optogenetic manipulation of the spindle positioning protein LIN-5. We uncovered that only some embryos tolerated equalization, and that there was a size asymmetry threshold for viability. Cell lineage analysis of equalized embryos revealed an array of defects, including faster cell cycle progression in P1descendants, as well as defects in cell positioning, division orientation, and cell fate. Moreover, equalized embryos were more susceptible to external compression. Overall, we conclude that unequal first cleavage is essential for invariably successful embryonic development ofC. elegans.
COVID-19 CG enables SARS-CoV-2 mutation and lineage tracking by locations and dates of interest

Published: February 2021

COVID-19 CG (covidcg.org) is an open resource for tracking SARS-CoV-2 single-nucleotide variations (SNVs), lineages, and clades using the virus genomes on the GISAID database while filtering by location, date, gene, and mutation of interest. COVID-19 CG provides significant time, labor, and cost-saving utility to projects on SARS-CoV-2 transmission, evolution, diagnostics, therapeutics, vaccines, and intervention tracking. Here, we describe case studies in which users can interrogate (1) SNVs in the SARS-CoV-2 spike receptor binding domain (RBD) across different geographical regions to inform the design and testing of therapeutics, (2) SNVs that may impact the sensitivity of commonly used diagnostic primers, and (3) the emergence of a dominant lineage harboring an S477N RBD mutation in Australia in 2020. To accelerate COVID-19 efforts, COVID-19 CG will be upgraded with new features for users to rapidly pinpoint mutations as the virus evolves throughout the pandemic and in response to therapeutic and public health interventions.

The X-linked geneRlimplays major roles in female mouse development and reproduction, where it is crucial for the maintenance of imprinted X chromosome inactivation in extraembryonic tissues of embryos. However, while females carrying a systemicRlimknockout (KO) die around implantation, maleRlimKO mice appear healthy and are fertile. Here, we report an important role forRlimin testis where it is highly expressed in post-meiotic round spermatids as well as in Sertoli cells. Systemic deletion of theRlimgene results in lower numbers of mature sperm that contains excess cytoplasm, leading to decreased sperm motility and in vitro fertilization rates. Targeting the conditionalRlimcKO specifically to the spermatogenic cell lineage largely recapitulates this phenotype. These results reveal functions ofRlimin male reproduction specifically in round spermatids during spermiogenesis.
Otitis media detection using tympanic membrane images with a novel multi-class machine learning algorithm
Authors: Alhudhaif Adi , Cömert Zafer , Polat Kemal
Published: February 2021

Background

Otitis media (OM) is the infection and inflammation of the mucous membrane covering the Eustachian with the airy cavities of the middle ear and temporal bone. OM is also one of the most common ailments. In clinical practice, the diagnosis of OM is carried out by visual inspection of otoscope images. This vulnerable process is subjective and error-prone.

Methods

In this study, a novel computer-aided decision support model based on the convolutional neural network (CNN) has been developed. To improve the generalized ability of the proposed model, a combination of the channel and spatial model (CBAM), residual blocks, and hypercolumn technique is embedded into the proposed model. All experiments were performed on an open-access tympanic membrane dataset that consists of 956 otoscopes images collected into five classes.

Results

The proposed model yielded satisfactory classification achievement. The model ensured an overall accuracy of 98.26%, sensitivity of 97.68%, and specificity of 99.30%. The proposed model produced rather superior results compared to the pre-trained CNNs such as AlexNet, VGG-Nets, GoogLeNet, and ResNets. Consequently, this study points out that the CNN model equipped with the advanced image processing techniques is useful for OM diagnosis. The proposed model may help to field specialists in achieving objective and repeatable results, decreasing misdiagnosis rate, and supporting the decision-making processes.

Dear contributors:

After 5 consecutive years as editor-in-chief of Ciencias Marinas, Dr. Alejandro Cabello Pasini has now abdicated this position to undertake other academic projects at the Autonomous University of Baja California (Mexico). This change in editorship concurs with the 45th anniversary of the establishment of Ciencias Marinas and marks the beginning of a new phase in the growth and development of our scholarly journal. The editorial team has thus far completed many projects, such as updating our publishing platform, all aimed to improve journal presentation, visibility, and accessibility. It has now taken the first steps in transitioning from an electronic publishing format to a completely digital format, and it will continue to work hard to guarantee that Ciencias Marinas continues evolving.

Over these past 45 years Ciencias Marinas has been a conduit for the professional and inclusive delivery of sound scientific information on the four disciplines of marine science (biology, physics, geology, and chemistry). At the moment we are focusing on strengthening our international support system to reach higher publishing standards. To achieve this goal, we are expanding, refining, and updating our editorial board, which now includes even more international experts with outstanding academic careers. We will continue to expand our editorial board by extending additional invitations to other experts who wish to collaborate in this project that is Ciencias Marinas, and we hope to soon welcome new member to our board.

I would now like to take the opportunity to thank previous editors-in-chief for their contributions, which have elevated our journal to its current position. Their contributions give me a great advantage to further improve the quality of the journal products. I am also thankful to the members of the editorial board, who have provided much support by efficiently and professionally managing the editorial processes of our submissions. As a result of this work, our list of reviewers has significantly increased in number and quality, and this will reflect on the quality of the papers we publish. We are working our way to better our remote communication with the editorial board so we can jointly establish new publication strategies aimed to improve the quality of our journal and its impact in the scientific community.

I want to thank the Autonomous University of Baja California for all the support it has provided over these past 45 years for the upkeep of the journal. My thanks go to the editorial office administration staff, who have done and continue doing an excellent job, and to the reviewers, the readers, and the authors, because without them this journal would not be what it is today. We will keep working with everyone to continually improve Ciencias Marinas, and we hope we continue receiving your contributions. In the meantime, please feel free to visit our website and check our new journal cover and other new things we have set up you.

Sincerely,

Miguel Angel Huerta Díaz

Introduction: Corneal damage is the common issue affecting 70% of diabetic patients. Diabetic cornea has functional abnormalities such as decreased corneal Endothelial Cell Density (ECD), thicker corneas with increased endothelial permeability, lesser corneal sensitivity, and elevated corneal auto-fluorescence. Aim: To study the corneal endothelial characteristics among diabetic patients and to identify the factors associated with endothelial damage and compare the corneal changes based on the duration of diabetes mellitus and glycaemic control. Materials and Methods: The hospital based cross-sectional study was conducted in 155 patients (100 diabetic and 55 control) from 24th September 2016 to 29th March 2018. The corneal endothelial morphological features were evaluated using a non-contact EM-3000 specular microscope. The morphological characteristics of endothelial cell like the ECD, Coefficient of Variation (CV), Central Corneal Thickness (CCT), and percentage of hexagonal cells were compared between diabetic patients and the control population. Age, gender, blood pressure, duration of diabetes, fasting and Postprandial Blood Sugar (PPBS) HbA1c value, blood urea, and serum creatinine, Intra Ocular Pressure (IOP) were also recorded, and the endothelial cell characteristics were compared between the diabetic groups according to the duration (< or ≥ 3 years) and HbA1c% (< or ≥ 7%). An independent t-test was performed to compare the means of endothelial characteristics between study subjects and the control group and also between duration of diabetes and HbA1C levels. A p-value of less than 0.05 was considered statistically significant. The data were analysed using a SPSS statistical program. Results: Baseline characteristics like Fasting Blood Sugar (FBS), PPBS, HbA1c, Systolic and Diastolic Blood Pressure (SBP and DBP) were significantly higher in diabetic group than control. A significant difference in corneal thickness (p=0.01) and hexagonality (p<0.001) were also observed between both the groups. The diabetic group showed a reduction in cell density and a higher coefficient variation of cell size however the differences were not statistically significant, There was no significant difference in the ECD, CCT, CV, and hexagonality irrespective to HbA1c level and duration of diabetes. Conclusion: Patients with diabetes had a significant increase in corneal thickness, and a higher frequency of pleomorphism compared to control subjects. In terms of ECD and co-efficient variation, no difference was observed between groups.

Tuberculosis (TB) strains with drug resistance are more difficult to treat than drug susceptible ones and jeopardise global progress towards the targets set by the World Health Organisation’s End TB Strategy. Although disseminated TB is well known as an opportunistic infection in HIV infected individuals, it is uncommon in HIV negative individuals. The present case is a rare case of Extensively Drug Resistant (XDR)-TB in disseminated TB involving the extrapulmonary sites in an immunocompetent adult. We report a case of a young man who has disseminated TB involving pleura and peritoneum. Prior to this, he had taken category II anti-TB treatment with no satisfactory response. Drug sensitivity test of pleural fluid revealed resistance to quinolones, kanamycin, isoniazid and rifampicin. Patient was administered second line anti-TB therapy with remarkable response. Therefore, this case highlights the importance of investigating aggressively for Drug Resistance (DR) in suspected cases of extrapulmonary TB

A 70-year-old female reported with complaints of defective vision in both eyes. Ophthalmological examination of both eyes revealed well-centred Posterior Chamber Intraocular Lens (PCIOL), thin membranous Posterior Capsular Opacification (PCO) with no signs of inflammation, myopic fundus and normal Intraocular Pressure (IOP). She had history of uneventful cataract surgery in both eyes four years back and was on treatment for diabetes mellitus and chronic obstructive pulmonary disease. PCO was managed with Nd: YAG capsulotomy in both eyes. After ten hours, patient reported back with severe headache, right-sided periorbital pain and profound diminution of vision. Examination revealed corneal oedema, shallow Anterior Chamber (AC) and raised IOP in her right eye. Patient was admitted and treated with parenteral and local IOP lowering agents and cycloplegic agents. Once the IOP was lowered and cornea cleared, slit lamp examination revealed vitreous blocking the pupil resulting in secondary angle closure which was confirmed by Anterior Segment Optical Coherence Tomography (AS-OCT). Nd:YAG LASER peripheral iridotomy was done to relieve the pupillary block. This is presented as a rare case of pupillary block following Nd:YAG capsulotomy in the presence of well-centred PCIOL

Soil-Transmitted Helminths (STH) or geohelminths are an important cause of morbidity worldwide. A large proportion of the infection burden occurs in India, including STH infections due to roundworms (Ascaris lumbricoides), whipworms (Trichuris trichura) and hookworms (Necator americanus or Ancyclostoma duodenale). Apart from direct health impacts, they are also implicated in anaemia, nutritional deficiencies and delayed cognitive development in children. They also have been shown to have detrimental impact on economic development and future income earning potential. The current global strategy on STH control is through increased utilisation of Preventive Chemotherapy (PC) for at-risk population, comprising mainly pre-school and school age children. This is crucial for India, as there can be significant proportion of untreated subjects in the community, who may act as a reservoir of infection for treated subjects to get re-infected. Additionally, inculcating healthy behaviour modifications and adopting WASH interventions meant a major shift in social and cultural norms in many societies. Overall, the multifaceted nature of STH control in India requires concerted efforts and significant mobilisation of human and financial resources. In this regard, several recent initiatives including Swachh Bharat Abhiyan, Nirmal Gram Puraskar, Water Sanitation and Hygiene (WASH) interventions, Clean India: Clean schools etc., have brought a positive change, apart from the provision of deworming for morbidity control through National Deworming Day. In this paper, authors have narrated major initiatives in recent years that are expected to bring a lasting solution to the problem of STH infection in India.
