Authors: Ferreira Suzana Aparecida da Costa , González Carol Viviana Serna , Thum Magali , Faresin Adriane Aparecida da Costa , Woo Kevin , Santos Vera Lúcia Conceição de Gouveia
Published: August 2022

Objetivos: Mapear e sintetizar a literatura existente sobre terapias tópicas para o manejo da dor em feridas neoplásicas malignas e as lacunas de pesquisa.
Introdução: A maioria dos pacientes com feridas neoplásicas malignas sente dor relacionada à ferida, o que afeta sua qualidade de vida. Infelizmente, apesar da dor ser um sintoma relevante tanto no tratamento oncológico quanto nos cuidados paliativos, pouco se sabe atualmente sobre a disponibilidade de tratamentos tópicos e seu impacto no controle da dor.
Desenho: Revisão do escopo de acordo com a metodologia JBI®.
Métodos: CINAHL, LILACS, Embase, Web of Science, PubMed, Cochrane, NICE, Scopus, JBISRIR e bases de dados de literatura cinzenta foram pesquisados; em inglês, espanhol e português, sem limite de tempo. Dois autores revisaram todas as citações de forma independente. Estudos em adultos com feridas neoplásicas malignas relatando intervenções tópicas para dor foram incluídos. Adicionalmente, foi desenvolvido um instrumento de extração de dados para a síntese e análise do tema. Este estudo seguiu a lista de verificação do relatório de revisão de escopo PRISMA-ScR da rede Equator.
Resultados: Foram selecionadas 70 publicações dentre 796 identificadas nas bases de dados. Os estudos incluíram principalmente revisões não sistemáticas e estudos de caso; apenas seis eram ensaios clínicos. De acordo com a síntese narrativa realizada, foram identificadas vinte terapias, que incluíram o uso de curativos (58,6%), analgésicos (55,7%), antimicrobianos tópicos (25,7%), protetores cutâneos (15,7%), crioterapia (5,7%). , e terapia com pressão negativa (4,3%). Várias terapias tópicas foram recomendadas para o leito da ferida e a área periferida. Em 68,5% dos estudos não foi descrita a aplicação de instrumentos para avaliação da dor.
Conclusões: foram identificadas terapias tópicas aplicadas no leito de feridas neoplásicas malignas ou na área perilesional, para controle da dor. No entanto, a eficácia das intervenções foi analisada por poucos estudos clínicos, indicando a necessidade de mais estudos primários que informem a prática clínica baseada em evidências.
Implicações para a prática: o uso de opioides, anestésicos e antimicrobianos se destaca pela aplicação clínica, com resultados positivos em ensaios clínicos randomizados. Este estudo não incluiu pacientes.

Published: August 2022

Este estudo organiza-se em torno da seguinte questão: quais as tessituras didático pedagógicas possíveis de serem empreendidas em educação física no/com/o cotidiano do ensino médio, a partir de (re) apropriações sobre as estruturas curriculares? Objetiva analisar como a articulação entres signos curriculares podem materializar-se como ações didático pedagógicas no cotidiano do ensino médio. Para tanto, realizou-se um estudo de caso etnográfico do cotidiano escolar com princípios da pesquisa ação existencial. Em outras palavras, o contexto de tensões, mudanças e reorganizações no qual o ensino médio brasileiro se apresenta e seus impactos na Educação Física constituem-se como campo fértil para esse tipo de opção metodológica. Nessa perspectiva, passou-se a integrar o cotidiano de uma escola de tempo integral da rede estadual Capixaba, fundada em 1977. Desse modo, durante aproximadamente 700 aulas de Educação Física, que envolveram ação direta com uma professora do componente curricular, dez turmas de 1º ao 3º ano e cerca de 400 alunos, buscou-se dar visibilidade aos saberes/fazeres mobilizados nos espaços/tempos desse cotidiano. Os resultados sinalizam ações educacionais em Educação Física que respeitem as particularidades próprias dos cotidianos escolares praticados. Sendo assim, o que está sendo proposto representa uma resposta aos acontecimentos gerais advindos das políticas educacionais nacionais, mas representam também respostas aos problemas e dilemas próprios do cotidiano da escola pesquisada.
Shrinkage of high-strength engineered cementitious composite with zeolite particles as internal curing agent
Authors: Wang Qing , Huang Wenjie , Sun Jing , Zhang Jun
Published: August 2022

The shrinkage and internal relative humidity (RH) of internally cured high-strength engineered cementitious composites (HSECCs) based on ordinary Portland cement (OPC) were experimentally investigated. Natural zeolite and calcined zeolite particles were used as internal curing agents. The effect of calcination and substitution ratio of zeolite on the shrinkage reduction efficiency and the compressive strength of the composites was evaluated. The test results showed that the development of shrinkage and internal RH of the OPC-HSECCs followed a two-stage pattern. Regarding shrinkage reduction of the OPC-HSECCs, the efficiency of the pre-wetted calcined zeolite particles was greater than that of the natural zeolite; the total shrinkage was reduced by more than 54% at 28 days and the compressive strength was similar to the control. The optimum replacement ratio of calcined zeolite was determined to be around 30%.
Electrical conductivity of sand–clay mixtures
Authors: Al-Moadhen Muataz M. , Clarke Barry G. , Chen Xiaohui
Published: August 2022

This paper presents the results of the electrical conductivity measurements of sand–clay mixtures that were formed of three types of sands and five pure clays and prepared with water of low salinity. The results show that an increase in clay content results in an increase in the overall electrical conductivity. Moreover, a direct or inverse relationship between the overall soil electrical conductivity (σ T) and porosity (n) is observed depending on whether the water conductivity (σw) is higher or lower than the clay particle surface conductivity (σ s). Common predictive models for electrical conductivity were developed for sands and clayey sands with a clay content of less than 20%. This research extended these studies to include clays, sandy clays and clayey sands to show that it is possible to predict the electrical conductivity of a soil from its composition and fabric.

Authors: Yang Guohui , Jiang Linhua , Zhi Fangfang , Jin Weizhun , Li Geyang
Published: August 2022

The purpose of this study is to evaluate the influence of cation types on the rust resistance performance of new nucleic acid corrosion inhibitors in simulated concrete pore solution. Four common chlorinated ice salts (sodium chloride (NaCl), potassium choride (KCl), calcium chloride (CaCl2) and magnesium chloride (MgCl2)) were selected to study the corrosion behaviour of chloride ions by linear polarisation resistance method, electrochemical impedance spectroscopy and X-ray photoelectron spectroscopy. The results show that the cationic type will affect the thickness of the passivated film on the steel surface and the compactness of the passivated film formed by iron oxide and nucleic acid rust inhibitor. The type of cations affects the critical chloride concentration of nucleic acid inhibitor, following Na+ ≈ K+ > Ca2+ > Mg2+.

Asia siglo XXI: oportunidad para diversificar la política exterior colombiana
Authors: García Pío
Published: August 2022

Asia was reborn as a continent with great productive, commercial, and innovation capacities that have impacted the international system, thus challenging Colombian foreign policy. Over the last century, the accepted subordination to US global strategic design was the main characteristic of this country’s foreign policy. The objective of this article is to present the requirements that an assertive response implies in face of the Asian global challenge. In this regard, it is argued that, given the size and development conditions of Colombia, a policy towards Asia requires improving its negotiation capacity. This requires a robust Latin American regional integration program. In the domestic context, it is also essential to advance the democratization of the external agenda by enriching the deliberation process via the incorporation of new agents, beyond bureaucratic teams, and the business community.
The Linguistic Features of Translanguaging Interactions in Singapore: A Discourse Analysis Perspective
Authors: An Wenzhao
Published: August 2022

Translanguaging has been researched as a heated topic about multilingual discourse studies. However, there were few studies observing from the perspective of translanguaging among Chinese Singaporeans in routine conversations, which is a research gap. Accordingly, this paper aims to examine the nature and discuss the influencing factors of translanguaging among Chinese-English bilinguals in Singapore with the use of discourse analysis as a research method. Major findings were: 1) some Chinese-English bilinguals were more efficient in English than others; 2) Singapore's localized and multilingual use of English have resulted in Colloquial Singapore English or Singlish; 3) influencing factors of translanguaging shown in the clips include students’ inadequate training for learning English as a second language, teachers’ time constraints, and teachers’ limited resources to incorporate support strategies for students, which were restricted by schools. Nonetheless, the contribution of this study is to explore the nature of translanguaging of Chinese-English Bilinguals, especially in the Singapore context, which will provide further implications for Singaporean English discourse studies.

The Western world is currently facing a persistent shortage of skilled workers. Well-trained employees are difficult to find and even more challenging to retain. Employees, therefore, expect the best working conditions. Companies initiate New Work approaches in response to dynamic changes. This study examines the requirements for New Work design from the perspective of commercial employees to offer small and medium-sized enterprises (SMEs) guidance to find the optimal workplace development for their employees. A qualitative research method in the form of guided interviews was used to explore the needs of employees. The results suggest that employees desire an adapted work structure and change in the sense of New Work. Based on the study results, seven design areas were derived and recommendations for action were developed for the respective areas. Requirements and patterns are identified across several principles and design areas. Based on the results, strategies for implementation were developed.

Актуальность. Статья посвящена расчёту распределения температуры в пласте при использовании парогравитационного дренажа и определению времени прогрева межскважинной зоны с помощью численного решения дифференциального уравнения теплопроводности при многомерной постановке задачи. В связи со значительной долей высоковязкой нефти среди мировых запасов углеводородов актуальным становится применение для добычи такой нефти методов увеличения нефтеотдачи, в том числе метода парогравитационного дренажа. Существующие модели для оценки температуры на стадии инициации процесса не учитывают протяжённости горизонтальной скважины, распределения температуры в нагнетательной скважине или влияния нагнетательных скважин от соседних элементов разработки. Предлагаемая математическая модель впервые учитывает интерференцию скважин. Целью работы является определение времени прогрева межскважинной области с учётом интерференции нагнетательных скважин с помощью численного решения многомерного уравнения теплопроводности. Методы. Рассматриваются двумерная и трёхмерная задачи теплопроводности, температура в стволе нагнетательной скважины считается меняющейся по линейному закону из-за тепловых потерь, учитывается влияние на температуру в добывающей скважине не только ближайшей нагнетательной скважины, но и четырёх соседних нагнетательных скважин. Результаты. Рассчитана динамика температуры в одной из добывающих скважин с учётом влияния не только ближайших нагнетательных скважин, но и нескольких нагнетательных скважин из соседних элементов разработки. Показано, что динамики температуры в добывающей скважине для двумерной и трёхмерной постановок задачи соответствуют друг другу, поэтому распределение температуры в пласте не зависит от угловой координаты. Определено время прогрева зоны между нагнетательной и добывающей скважинами, когда нефть становится достаточной подвижной, чтобы обеспечить приток к добывающей скважине. Проведена верификация модели путём сопоставления распределения температуры в пласте с данными по модели Ли и Чена.

Актуальность. Добываемая нефть большинства месторождений нашей страны имеет значительную обводненность. Содержание воды в нефти достигает 98–99 %. Перекачка нефти с водой по промысловым трубопроводам очень неэкономична. Поэтому нефтяная промышленность испытывает потребность в установках для отделения воды (дегидраторах). Существует несколько способов дегидрации: химические, механические, термические и электрические методы. Все эти методы имеют свои достоинства и недостатки. В статье предлагается электромагнитный дегидратор, в котором используется совместное воздействие электрического и магнитного полей. Авторами предложена оригинальная конструкция магнитоэлектродегидратора, предназначенного для эксплуатации в нефтяной промышленности в целях обезвоживания и обессоливания нефти. В данном устройстве электрическое поле создается системой электродов, а пульсирующее магнитное поле – однофазной обмоткой. Под воздействием электрического поля заряженные частицы воды начинают двигаться к противоположно заряженному электроду, при этом разноименно заряженные капли двигаются навстречу друг другу. Обмотка создает пульсирующее магнитное поле, которое индуцирует в каплях воды вихревые токи и взаимодействует с магнитными полями, создаваемыми этими токами. Совместное воздействие электрического и магнитного полей увеличивает частоту столкновений капель, что приводит к их слиянию и увеличению размера. Вследствие этого капли быстрее осаждаются под действием силы тяжести, что позволяет увеличить производительность дегидратора. Цель: разработать конструкцию магнитоэлектродегидратора и провести исследование его характеристик; построить математическую модель процессов разделения воды и нефти и получить графики зависимостей; сформулировать требования к источникам питания для электромагнитных дегидраторов. Объекты: установки подготовки нефти, дегидраторы для разделения водонефтяных эмульсий, установки с электромагнитным воздействием. Методы: теория электрического поля, теория магнитного поля, математическое моделирование, программа для математических и инженерных вычислений Mathcad. Результаты. Предложена конструкция магнитоэлектродегидратора, математическая модель процессов разделения воды и нефти. Получены графики зависимостей магнитной индукции от частоты и производительности дегидратора. Построена зависимость времени между столкновениями капель от частоты магнитного поля. Сформулированы требования к источнику питания для электромагнитного дегидратора.
ВЗАИМОДЕЙСТВИЕ КАПЕЛЬ ОГНЕТУШАЩИХ СОСТАВОВ С ФРАГМЕНТАМИ ГОРЮЧИХ МАТЕРИАЛОВ
Authors: Жданова Алена Олеговна , Исламова Анастасия Гомильевна , Копылов Николай Петрович
Published: August 2022

Актуальность. Наиболее распространенным огнетушащим составом для локализации и ликвидации возгораний природного и техногенного характера является вода. Практически ежегодное увеличение площадей возгораний бореальной зоны, а также удаленности очагов возгорания от водоисточников обуславливает необходимость повышения ресурсоэффективности тушения. Основной задачей при тушении техногенных возгораний является снижение расхода огнетушащих средств, что позволит снизить риск чрезмерного заливания водой помещений и сократить материальные затраты на восстановление объектов. Для этих целей целесообразно совершенствовать существующие и разрабатывать новые огнетушащие составы. Недостаточная изученность процессов, происходящих при взаимодействии капель различных типичных огнетушащих жидкостей с поверхностью горючих материалов, и высокая научно-практическая значимость подобных исследований обуславливает актуальность. Цель: установление закономерностей смачивания, растекания и испарения капель огнетушащих составов по поверхностям горючих материалов при кондуктивном нагреве. Объект: огнетушащие составы (вода; растворы антипирена, ФР-Лес, бишофита; суспензии бентонита; эмульсии пенообразователя) различной концентрации. Методы. Исследование процессов смачивания и испарения капель огнетушащих составов проводились методом «неподвижной» капли (размещенной на твердой поверхности с помощью электронного дозатора). Для определения геометрических характеристик капель применялась теневая оптическая система, полученные изображения обрабатывались с помощью специального программного обеспечения методами «тангенциальный 1» и «Юнга–Лапласа». Результаты. Установлены основные закономерности смачивания и испарения капель огнетушащих составов на поверхностях горючих материалов (листьев березы, древесины, ламинированной древесно-стружечной плите, линолеуме и поливинилхлориде). Показано, что при подавлении пиролиза горючих материалов в глубине слоя более эффективными будут составы с меньшим поверхностным натяжением, проникающие в более глубокие слои горючего материала. В таких условиях охлаждаются нагретые до высоких температур фрагменты материалов и подавляется процесс генерации горючего – газообразных продуктов термического разложения. Установлено, что доминирующим механизмом подавления горения и пиролиза при тушении горючих материалов (а именно при использовании антипиренов, бишофита, бентонита, ФР-Лес) является формирование защитного слоя на поверхности элементов веществ и материалов, а не поглощение теплоты при испарении растворителя. Зависимости средних по времени скоростей испарения капель огнетушащих составов от температуры нагрева поверхности описаны экспоненциальной кривой WE  = a∙Tb.
СУБЪЕКТЫ И ПОЗИЦИИ НА ДИСКУРСИВНОЙ АРЕНЕ «УГОЛЬНОГО РЕГИОНА»: МЕДИАПОВСЕДНЕВНОСТЬ КУЗБАССА
Authors: Пискунова Александра Евгеньевна
Published: August 2022

Статья посвящена осмыслению медиапространства Кузбасса, в котором сформирована дискурсивная среда, заданная динамикой смыслов, образов, символов, сфокусированных на контекстуальной интерпретации угля как ресурса. Цель – выявить механизмы и содержание процессов позиционирования в региональной медиасреде как явлений дискурсивного порядка. Методология: дискурсивный подход к анализу медиаполя «угольного региона». Основное внимание уделяется тому, как обсуждается угледобыча, что сказано, кто говорит и кто отсутствует в медиадискурсе. Результаты: анализ медиасвидетельств позволил идентифицировать различных акторов в сообществе, сформированном региональной моделью угольного экстрактивизма. В рамках медиаполя они вовлечены в коммуникативные практики оспаривания и (вос)производства интерсубъективной смысловой реальности. С одной стороны, это дискурсивная коалиция власти и добывающих компаний, которые маскируют заложенные в логику ресурсного экстрактивизма несправедливость и насилие риторикой угля как «общего блага». С другой – голоса «экспертов», которые выносят суждение об экологическом, экономическом, социальном состоянии региона (коренные народы и местные сообщества, непосредственно затронутые воздействием угледобычи), и голос «большинства», которое колеблется между разными позициями в силу политической и экономической лояльности и зависимости от угольной отрасли. Отмечается, что особые дискурсивные эффекты, властные диспозиции и культурные сюжеты глубоко встроены в социокультурную реальность Кузбасса, в которой уголь, как специфическая региональная символическая субстанция, является источником смыслопорождения.

La filière des cultures légumières est une composante importante de l'agriculture urbaine qui peut contribuer efficacement à la sécurité alimentaire. Cette étude vise à faire l’état des lieux de la filière maraichère au Gabon afin d’identifier les facteurs d’amélioration et de relance du secteur. Une enquête a été réalisée dans trois provinces (Estuaire, Ngounié et Wolleu Ntem) selon la méthode probabiliste aléatoire sur la base d’un questionnaire regroupant un ensemble de questions pour la collecte des informations. L’analyse des données a montré que l’activité maraichère est majoritairement pratiquée par les expatriés (87,87%) sur des sites de moins de 1 ha ; la plupart (53%) ayant une expérience de plus de 10 ans et des pratiques totalement manuelles. 65% des producteurs enquêtés ont un âge compris entre 30 et 50 ans. Le maraichage non seulement constitue (pour 79,61% des producteurs interviewés) leur source de revenus pour la famille, mais aussi contribue à 100% aux charges et dépenses de la famille. 8,7% seulement des acteurs sont dans une coopérative et 4% sont installés sur leur domaine personnel (ou familiale). Les semences utilisées proviennent des structures commerciales et le système d’association et de rotation de cultures est utilisé pour la gestion des cycles. 68,44% de ces producteurs ont pu installer des abris pour leur activité. Et 85,92% exercent leur activité sur financement propre. Concernant la production de tomate, les variétés utilisées généralement par les producteurs enquêtés sont des variétés hybrides F1 à croissance déterminé avec la variété Lindo retrouvée sur presque tous les sites de tomates. Les traitements (engrais ou produits phytosanitaires) diffèrent d’un producteur à un autre. La filière tomate ne possède aucun circuit organisé de gestion et transformation post récolte. Les tomates fraiches récoltées sont vendues sur place ou amenées vers le marché de proximité pour la vente.
Living Through a Pandemic: Competing Covid-19 Narratives in Rural Zimbabwe

Published: August 2022

Through a real time analysis of the Covid-19 pandemic across rural Zimbabwe, this Working Paper explores the competing narratives that framed responses and their politics. Based on 20 moments of reflection over two years, together with ongoing document and media analysis and an intensive period of qualitative interviewing, a complex, dynamic story of the pandemic ‘drama’ emerges, which contrasts with snapshot perspectives. Across the period, a science-led public health narrative intersects with a security and control narrative promoted by the state and is countered by a citizens’ narrative that emphasises autonomy, independence, and local innovation. The politics of this contestation over narratives about appropriate pandemic responses are examined over three periods – reflecting different waves of infection – and in relation to two conjunctures – an early, strict lockdown and the rollout of vaccines. Different narratives gain ascendancy and overlap at different times, but a local citizen-led narrative emerges strongly in the context of heavy-handed lockdowns, inadequate state capacity, and struggles around rural livelihoods. The pandemic has reshaped relationships between the state and citizens in important ways, with self-reliance rooted in local resilience central to local pandemic responses.
The Lived Experiences of Teachers with Visual Impairments in the Inclusion of Students with Visual Impairments: A Phenomenological Study
Authors: ŞENGÜL ERDEM Hatice , YAKUT Ayşe Dilşad
Published: August 2022

This study aims to reveal the lived experiences of teachers with visual impairments (VI) in the inclusion of students with VI. In this phenomenological study, data were collected from 8 teachers with VI through semi-structured interviews and analyzed by content analysis using a qualitative software program named MAXQDA20. The six themes identified from the content analysis were underlying issues in inclusion, personal guidance of teachers on students with VI, critical evaluation of inclusion, from diagnosis to the IEP implementation, the appropriate model of education for students with VI, and teachers' sense of inclusion. The findings revealed that teachers with VI contributed to the inclusion of students with VI. Furthermore, they emphasized system-related issues preventing inclusive practices and made critical evaluations concerning practices in inclusive settings. Based on the findings, inclusive classrooms and resource rooms should be equipped with educational tools (i.e., the braille alphabet, assistive technologies, tactile graphs and maps), teaching staff and their training should be enhanced, and school buildings should be designed as physically accessible and supervised by special education teachers who have expertise in VI or experience in working with students with VI.

Este artigo é um esforço inicial de enfrentar tais questões por meio da noção de “tecnologia aprofundada” de Gilbert Simondon (2014) em diálogo com análises recentes feitas no campo dos estudos críticos sobre IA que caminham na direção de investigar os fundamentos epistêmicos e de funcionamento da tecnologia e de propor formas não autocráticas de conceber e fazer funcionar sistemas de IA.
Heróis da travessia

Published: August 2022

O presente artigo tem por objeto o monumento dedicado aos aviadores De Pinedo e Ribeiro de Barros que cruzaram o Atlântico em 1927. Analisamos a composição do projeto fascista do Heróis da Travessia, buscando compreender o papel do mito de Roma na construção de laços entre a comunidade ítalo-paulista e a Itália durante o Ventennio. Por meio do exame da política externa italiana, que promoveu as crociere aeree como propaganda, e da análise iconográfica de sua materialidade, que mobiliza signos associados ao culto da romanidade, demonstramos que o monumento é estruturado antes de tudo como um elogio à Itália de Mussolini.

The main goal of this study was to compare energy consumption scenarios at a small-scale barn with an in situ biogas plant. Five life cycle assessment scenarios of dairy manure management were assessed. A real small-scale manure biogas power plant in Mexico (S-BPP) was used as case study. Five scenarios were modeled: (1.1) electricity consumption from the national grid; (1.2) electricity consumption considering a natural gas combined cycle power plant (CCPP); (2.1) partial use of electricity from the national grid and the electricity produced by the S-BPP; (2.2) partial use of electricity from the CCPP and the S-BPP, and (3) a dry anaerobic digestion S-BPP. A Monte Carlo simulation was carried out to manage the uncertainty with 95 % of confidence. A reduction of emissions in the combined cycle power grid by exploiting the manure to produce biogas, was established. Specifically, in the climate change category, there is an impact reduction by up to 70 %, which corroborates that the choice of small-scale biogas in agriculture systems is environmentally feasible. It is confirmed that using S-BPP produces a significant decrease of impacts when compared to CCPP. The results of the modeling scenarios, such as dry anaerobic digestion and/or combined cycle power plants, show a significant reduction in the emissions of the selected impact categories. This study confirms the need to develop more accurate databases of life cycle inventories regarding the Mexican electricity grid, in order to perform more reliable studies.
The Determinants of Lifelong Learning in Europe

Published: August 2022

The article affords the question of lifelong learning in Europe using data from the European Innovation Scoreboard-EIS in the period 2010-2019 for 36 countries. The econometric analysis is realized using WLS, Dynamic Panel, Pooled OLS, Panel Data with Fixed Effects and Random Effects. The results show that lifelong learning is, among other variables, positively associated to “Human Resources” and “Government procurement of advanced technology products” and is negatively associated, among others, to “Average annual GDP growth” and “Innovation Index”. A clusterization is realized using the k-Means algorithm with a confrontation between the Elbow Method and the Silhouette Coefficient. Subsequently, a Network Analysis was applied with the distance of Manhattan. The results show the presence of 4 complex and 2 simplified network structures. Finally, a comparison was made among eight machine learning algorithms for the prediction of the value of lifelong learning. The results show that the linear regression is the best predictor algorithm and that the level of lifelong learning is expected to growth on average by 1.12%.

Genomics involving tens of thousands of genes is a complex system determining phenotype. An interesting and vital issue is that how to integrate highly sparse genetic genomics data with a mass of minor effects into prediction model for improving prediction power. We find that deep learning method can work well to extract features by transforming highly sparse dichotomous data to lower dimensional continuous data in a non-linear way. This idea may provide benefits in risk prediction based on genome-wide data associated e.g. integrating most of the information in the genotype data. Hence, we developed a multi-stage strategy to extract information from highly sparse binary genotype data and applied it for risk prediction. Specifically, we first reduced the number of biomarkers via a univariable regression model to a moderate size. Then a trainable auto-encoder was used to extract compact representations from the reduced data. Next, we performed a LASSO problem process over a grid of tuning parameter values to select the optimal combination of extracted features. Finally, we applied such feature combination to two prognostic models, and evaluated predictive effect of the models. The results of simulation studies and real data applying indicated that these highly compressed transformation features could better improve predictive performance and did not easily lead to over-fitting.

Tissue programmed death ligand-1 (PD-L1) protein expression is predictive of immune checkpoint inhibitor (ICI) benefit. However, tissue PD-L1 can be fraught with tissue acquisition and heterogeneity limitations. Plasma testing can overcome these limitations. However, the overall survival (OS) predictive benefit of plasma PD-L1 assays have not been well characterized. Patients with stage IV non-small cell lung cancer (NSCLC) and plasma cfRNA PD-L1 by PCR expression were identified and assessed for OS. 16 patients treated with front-line ICI-based regimens were assessed and represented a real-world patient population with over half with a performance status of 2 or greater. 10 contemporaneous patients at the same institution treated with chemotherapy alone were also identified and assessed. With a median follow-up of 33 months, median OS was 13 months with a 30% 3-year OS for the ICI treated patients compared to a median OS of 3 months and a 10% 3-year OS for those treated with chemotherapy alone. Comparative log-rank test p-value = 0.014 and a hazard ratio 0.376 (95%-CI 0.134-1.057). Plasma cfRNA PD-L1 was associated with a statistically significant survival benefit from ICI-based treatment compared to chemotherapy in the first line treatment of a real-world patient population of advanced NSCLC.

Cobalamin is an essential nutrient required for the normal functioning of cells. Its deficiency can lead to various pathological states. Hydroxocobalamin (HOCbl) and cyanocobalamin (CNCbl) are the forms of vitamin B12 that are most commonly used for supplementation. There is substantial evidence indicating that cobalamins can both suppress and promote oxidative stress; however, the mechanisms underlying these effects are poorly understood. Here, it was shown that the oxidation of thiols catalyzed by HOCbl and CNCbl is accompanied by ROS production and induces, under certain conditions, oxidative stress and cell death. The form of vitamin B12 and the structure of thiol play a decisive role in these processes. It was found that the mechanisms and kinetics of thiol oxidation catalyzed by HOCbl and CNCbl differ substantially. It was discussed how these differences may explain different levels of ROS production and cytotoxicity induced by combinations of thiols with HOCbl and CNCbl. On the whole, the data obtained provide a new insight into the redox processes in which cobalamins are involved and might be helpful in developing new approaches to the treatment of some cobalamin-responsive disorders in which oxidative stress is an important component. In addition, these data may be useful for a better understanding of mechanisms underlying induction of different types of death of cancer cells and in a search for new targets for anticancer therapy.

The health seriousness due to the Covid-19 virus pandemic that has been installed worldwide since 2019 has brought news in all areas of social life. In Brazil, the federal government has little to do with public policies aimed at social areas. While science, in addition to numerous assumptions and being the object of government denialist discourses, has sought to contribute to the clarification of the phenomenon of the pandemic and its impacts on society. Therefore, the present study sought to analyze the panorama of research, in the period 2020 and 2021, on basic education in times of a pandemic. For that, from a qualitative approach, a bibliographic research was carried out in which 11 works were selected. The investigations demonstrate that the option for distance teaching has proved to be the main alternative for the educational offer in this scenario, but its implementation accentuates the educational inequalities that exist in the country.
