Abstract Multiple-choice item-based tests often use Item Response Theory for parameter estimation within dichotomous models. However, the Nominal Response Model allows the study of polytomous items, considering all the information obtained from the analysis of alternatives chosen by respondents. In this regard, the present research aims to interpret the content and alternatives of the Enade 2017 items related to Mathematics Teaching courses to contribute to a deeper edumetric analysis of the said test. It is a quanti-qualitative approach that concurrently employs the Nominal Response Model and the perspective of mathematics error analysis. The results indicate that the Enade 2017 test for the Mathematics Teaching course contained items with weaknesses in technical aspects in terms of clarity, relevance, or difficulty, requiring review by experts in the field. Furthermore, the analysis of these items helped clarify some of the respondents’ reasoning.

Resumen: Las pruebas basadas en ítems de opción múltiple a menudo utilizan la Teoría de la Respuesta al Ítem para la estimación de parámetros dentro de modelos dicotómicos. Sin embargo, el Modelo de Respuesta Nominal permite estudiar ítems politómicos, considerando toda la información obtenida en el análisis de las alternativas elegidas por los encuestados. En este sentido, la presente investigación tiene como objetivo interpretar el contenido y las alternativas de los ítems del Enade 2017 relacionados con los cursos de Licenciatura en Matemáticas, con el fin de contribuir a un análisis edumétrico más profundo de dicho examen. Se trata de un enfoque cuanti-cualitativo que utiliza simultáneamente el Modelo de Respuesta Nominal y la perspectiva del análisis de errores en matemáticas. Los resultados indican que el examen Enade 2017 para el curso de Licenciatura en Matemáticas contenía ítems con debilidades en aspectos técnicos en términos de claridad, relevancia o dificultad, que requerían revisión por parte de expertos en el campo. Además, el análisis de estos ítems permitió explicar algunos razonamientos de los encuestados.

Resumo: Testes baseados em itens de múltipla escolha frequentemente utilizam a Teoria da Resposta ao Item para a estimação de parâmetros dentro de modelos dicotômicos. Contudo, o Modelo de Resposta Nominal permite estudar itens politômicos, considerando toda a informação obtida na análise das alternativas escolhidas pelos respondentes. Nesse sentido, a presente pesquisa objetiva interpretar o conteúdo e as alternativas dos itens do Enade 2017 referentes aos cursos de Licenciatura em Matemática, a fim de contribuir para o aprofundamento da análise edumétrica do referido teste. Trata- se de uma abordagem quantiqualitativa que utiliza, concomitantemente, o Modelo de Resposta Nominal e a perspectiva da análise de erros em matemática. Os resultados indicam que o teste Enade 2017 para o curso de Licenciatura em Matemática continha itens com fragilidades em aspectos técnicos em termos de clareza, pertinência ou dificuldade, com necessidade de revisão por experts da área. Além disso, a análise desses itens permitiu explicar alguns raciocínios dos respondentes.

Abstract Objectives: To detect RSV or other thirteen respiratory viruses as possible causer agent of bronchiolitis in infants. Method: This is an epidemiological analytical study, conducted using a nasopharyngeal aspirate of 173 hospitalized children younger than two years old with severe bronchiolitis in three hospitals in the Campinas Metropolitan Region (CMR) during 2013-14. The data was statically evaluated by Pearson’s chi-squared test with statistical significance of 0.05 and 95% confidence level. Results: As expected, the most prevalent viruses detected were RSV A and B in 47% and 16% of the samples, respectively. However, almost a third of severe bronchiolitis cases there were no detection of RSV, and the viruses more commonly detected were rhinoviruses, which were identified in almost a quarter of all positive samples for at least a viral agent. Conclusions: Although nothing could be concluded from the disease severity and clinicalepidemiological data, the present study’s results indicate that severe bronchiolitis is not always related to RSV infections in children younger than two years old, and the rhinoviruses were more prevalent in these cases. These findings reinforce the need to carry out a

Resumo O momento da alfabetização pressupõe integrar os processos de ensino à realidade do sujeito, sendo incluso neste aspecto a ludicidade. Conhecer o potencial e as lacunas das pesquisas sobre a ludicidade e alfabetização estatística, possibilita fundamentar e evoluir as pesquisas nessa área. Assim, este estudo esboça um panorama do cenário nacional e internacional, das pesquisas sobre uso de jogos como instrumentos de ensino-aprendizagem-avaliação na Alfabetização Estatística, no período de 2010 a 2018, na forma de uma Revisão Sistemática de Literatura (RSL), a qual é proveniente de uma pesquisa de um programa de pós-graduação de uma universidade pública, que culminou em um produto educacional. A proposta fundamental da RSL foi mapear os artigos sobre o uso de jogos na Educação Básica, caracterizados como cooperativos, nas situações de ensino de análise combinatória. A RSL foi pautada na elaboração de questões de pesquisa, variedades de fontes, definição de critérios de inclusão e exclusão e análise dos artigos encontrados. Num primeiro momento, os artigos inclusos na pesquisa continham as palavras-chave jogo e Alfabetização Estatística , no repositório Scielo, Google Acadêmico e Eventos de Educação Estatística. Num segundo momento, a pesquisa foi delimitada, sendo considerados jogos relacionados ao conteúdo de análise combinatória na Educação Básica. Os dados obtidos, após uma construção metodológica que encontrou quinze artigos para análise, dão indícios de que ainda são recentes e em número reduzido as pesquisas que consideram aspectos lúdicos para a Alfabetização Estatística.

Abstract The time of children's literacy presupposes integrating teaching processes into the children's universe of which play takes part. Statistical literacy also needs to observe this context, organizing the contents in such a way that playfulness is an everyday practice. This study outlines an overview of the national and international scenario, of research on the use of games as teaching-learning-assessment tools in statistical literacy, from 2010 to 2018, in the form of a systematic literature review (SLR), which comes from research of a postgraduate program at a public university, which culminated in an educational product. The fundamental proposal of SLR was to map articles on the use of games in education, characterized as cooperative, in the hypotheses of teaching combinatorial analysis. The SLR was based on the formulation of research questions, variety of sources, definition of inclusion and exclusion criteria, and analysis of the articles found. At first, the articles included in the research contained the keywords game and statistical literacy , in the Scielo repository, Google Scholar, and statistical education events. Then, the research was delimited, including games related to the content of combinatorial analysis in basic education. The data obtained, after a methodological construction that found fifteen articles for analysis, give evidence that the articles are still recent and small in number as research that considers playful aspects for a statistical literacy.

Abstract Objective: To review the technical aspects of body composition assessment by dual-energy X-ray absorptiometry (DXA) and other methods based on the most recent scientific evidence. Materials and methods: This Official Position is a result of efforts by the Scientific Committee of the Brazilian Association of Bone Assessment and Metabolism (Associação Brasileira de Avaliação Óssea e Osteometabolismo, ABRASSO) and health care professionals with expertise in body composition assessment who were invited to contribute to the preparation of this document. The authors searched current databases for relevant publications. In this first part of the Official Position, the authors discuss the different methods and parameters used for body composition assessment, general principles of DXA, and aspects of the acquisition and analysis of DXA scans. Conclusion: Considering aspects of accuracy, precision, cost, duration, and ability to evaluate all three compartments, DXA is considered the gold-standard method for body composition assessment, particularly for the evaluation of fat mass. In order to ensure reliable, adequate, and reproducible DXA reports, great attention is required regarding quality control procedures, preparation, removal of external artifacts, imaging acquisition, and data analysis and interpretation.

BACKGROUND Zika virus (ZIKV) is an emerging arbovirus associated with foetal malformations and neurological complications. The infection is usually associated with mild symptoms. The comparison between the allelic frequency of polymorphic genes in symptomatic infected individuals in the population can clarify the pathogenic mechanisms of ZIKV. During ZIKV infection, cytokines are produced and natural killer (NK) cells are recruited, whose activation depends on signaling pathways activated by specific receptors, such as killer cell immunoglobulin-like receptors (KIR). These molecules interact with human leukocyte antigen (HLA) class I ligands and are encoded by polymorphic genes. OBJECTIVES This study aimed to evaluate the frequency of allelic variants of the genes encoding the KIR receptors and their HLA class I ligands in 139 symptomatic ZIKV-patients and 170 controls negative for the virus, and to evaluate the role of these variants for ZIKV susceptibility. METHODS KIR and HLA class I genes were genotyped using the polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO) technique. FINDINGS No significant differences in the frequency distribution of KIRs and KIR-HLA in patients compared to controls were observed. MAIN CONCLUSIONS KIR and its HLA ligands might play a minor role in ZIKV infection in the south and southeast Brazilian individuals.

ABSTRACT In 2022, an outbreak of monkeypox is being reported in non-endemic areas, with unusual clinical manifestations. The detailed clinical description of the first patient that received the diagnosis of monkeypox in Brazil is reported here, whose clinical manifestations can easily lead to misdiagnosis of sexually transmitted infections. A 41 years old male presented to an emergency room with a vesicular rash with eight days of evolution. He had traveled to Portugal and Spain and reported non-penetrative sexual involvement with three different male individuals. On the third day of symptoms, he sought medical care and received empirical treatment directed to sexually transmitted infections. As the symptoms did not improve, he sought medical attention at an infectious disease referral center presenting, on admission, an ulcerated penile lesion with central necrotic crusts, a disseminated pleomorphic skin rash and an oropharyngeal ulcer. The monkeypox diagnosis was suspected due to the characteristics of the lesions and the history of intimate contact with casual partners, and it was later confirmed by sequencing the almost complete monkeypox genome. The patient was hospitalized for pain control, which required opiate administration. He developed a secondary bacterial infection on the penile lesions, which were treated with oral antibiotics. He was discharged after 14 days, with lesions in process of re-epithelialization. Given the current outbreak, we must consider the possibility of monkeypox in patients with suggestive lesions, anywhere on the body (including the genitals), added to an epidemiological link or history of intimate contact with strangers or casual partners.

ABSTRACT Healthcare workers, the elderly and other vulnerable populations were the first to receive COVID-19 vaccines in public health programs. There were few vaccine safety data available on the elderly. This observational study aimed to evaluate the inactivated vaccine (CoronaVac) safety in the elderly, at the beginning of the vaccination program, in Sao Paulo city, Brazil. The elderly people that received CoronaVac at the Reference Center for Special Immunobiologicals (CRIE) or at home, administered by the Interdisciplinary Home Care Team (NADI) of the Hospital das Clinicas were invited to participate in this phase 4 observational study. The vaccination schedule included two CoronaVac doses 28 days apart. The information on solicited and unsolicited adverse events following immunization were collected by phone calls on days 4 and 8 after each vaccine dose. We enrolled 158 adults aged 65 to 101 years (mean of 84.1 years); 63.9% were females and 95.6% had chronic conditions, 21.5% had moderate or severe impairment in daily living activities; 34.2% were pre-frail and 19.6% were frail. We were able to contact 95.6% and 91.6% of the vaccinated people, after the first and second doses, respectively; 31.8% and 23.4% of the contacted participants reported some adverse events (AE) following the first and second doses, respectively. Pain at the injection site, fatigue, myalgia and headaches were the most frequent solicited AE. Most AE were mild to moderate. There were eight severe adverse events, but none of them were considered related to the vaccine. The CoronaVac was safe and well tolerated by these adults of advanced age with frailty and comorbidities.

Resumen Objetivo: Comparar in vitro la microfiltración apical en premolares unirradiculares obturados con cemento a base de resina epóxica y cemento biocerámico. Método: 40 piezas dentales unirradiculares fueron seleccionadas y divididas en dos grupos para ser obturadas esperando el tiempo de fraguado de acuerdo con las instrucciones del fabricante. El grupo A se obturó con cemento biocerámico Endosequence y, el grupo B, con cemento a base de resina epóxica AH-Plus: posteriormente los dos grupos fueron sellados con barniz de uñas hasta 3mm de la parte apical, luego se colocaron las muestras en la incubadora a 37ºC. Ambos fueron sometidos a 750 ciclos de termociclado, para reproducir el ambiente parecido a la cavidad oral. Para análisis de microfiltración se utilizó el método de difusión del colorante, se sumergieron en azul de metileno al 2 % por 6 días, posteriormente los especímenes fueron sometidos en una bomba de vacío. Los dientes fueron cortados longitudinalmente para ser evaluadas mediante el estereomicroscopio. El análisis estadístico fue hecho mediante T-Student y Chi-Cuadrado. Resultados: El grupo A corresponde a Endosequence obtuvo una medida de 0,55mm y el grupo B corresponde a AH-Plus 1,20mm con un estimado de significancia de p=0,013. Conclusión: El análisis de ambos cementos de obturación demostró que Endosequence posee menor microfiltración apical que AH-Plus.

Abstract Aim: To compare in vitro by the stereomiscroscope the lesser apical microfiltration in uniradicular premolars, between the cement based on Epoxy Resin and Bioceramic cement. Method: The study was performed on 40 uniradicular dental pieces divided into two groups, the samples were prepared using the protaper system and the obturation was performed using the lateral condensation technique, the first group was sealed withEndosequence bioceramic cement and the second group with Cement based on AH-Plus epoxy resin, then sealed with nail varnish up to 3mm from the apical part, then the samples were placed in the incubator at 37ºC, waiting for the set time corresponding to each group according to the manufacturer’s instructions . The two groups of the present study were submitted to 750 cycles of thermocycling, to provide an environment similar to the oral cavity, then longitudinal cuts were made to the samples. The microfiltration was evaluated using the dye diffusion method, immersed in 2% methylene blue for 6 days, then the specimens were subjected to a vacuum pump. The teeth were cut longitudinally to be evaluated by the stereomicroscope. The statistical analysis was through T-Student and Chi-Square. Results: Group A corresponds to Endosequence obtained a mean of 0,55mm and Group B corresponds to AH-Plus 1,20mm with an estimated significance of p = 0,013. Conclusion: Both obturation cements have significant differences, therefore Endosequence has less apical microfiltration than AHPlus.

Abstract Vasconcellea quercifolia A.St-Hil. (Caricaceae) is a non-conventional food plant (PANC) of Brazil. The aim of this study was to investigate the physical, chemical, and nutritional properties of green and ripe fruits and medullary parenchyma of V. quercifolia A.St-Hil., in order to develop functional foods. We determined humidity, pH, ash content, protein content, carbohydrate content, fibre content, carotenoid content, ascorbic acid content, and aminograms of green and ripe fruits and of medullary parenchyma from three specimens, following existing methodologies. Green fruits had higher protein and fibre contents, and ripe fruits had higher ash, carbohydrate, and carotenoid contents, higher than other most consumed fruits. On the other hand, medullary parenchyma had higher ash content and humidity. Glutamic acid, aspartic acid, and lysine were the amino acids with the highest contents, mainly in green fruits. Aside from medullary parenchyma, used as food in the past, both green and ripe fruits can be used for the development of new food products with functional properties and potential for new alternatives for consumption.

Abstract We assessed the effect of a new coating material based on resin-modified glass-ionomer with calcium (Ca) in inhibiting the demineralization of underlying and adjacent areas surrounding caries-like lesions in enamel. The measures used were surface hardness (SH) and cross-sectional hardness (CSH). Thirty-six bovine enamel specimens (3 × 6 × 2 mm) were randomly allocated into three groups (n = 12): No treatment (NT); resin-modified glass-ionomer with Ca (Clinpro XT Varnish, 3M ESPE) (CL), and fluoride varnish (Duraphat, Colgate) (DU). The specimens were subjected to alternated immersions in demineralizing (6 h) and remineralizing solutions (18 h) for 7 days. SH measurements were conducted at standard distances of 150, 300, and 450 µm from the treatment area. CSH evaluated the mean hardness profile over the depth of the enamel surface and at standard distances from the materials. The energy-dispersive X-ray spectroscopy analysis was conducted to evaluate the demineralization bands created on the sublayer by % of calcium (Ca), phosphorus (P), and fluoride (F). Ca/P weight ratio was also calculated. Based on SH and CSH measurements, there was no difference between groups at the distances 150 µm (p = 0.882), 300 µm (p = 0.995), and 450 µm (p = 0.998). Up to 50 µm depth (at 150 µm from the treatment area), CL showed better performance than DU ( p< 0.05). NT presented higher loss of Ca and P than CL and DU (p < 0.05). There was no significant difference in the % of F ion among the three groups. The new coating material was similar to F varnish in attenuating enamel demineralization.

RESUMO: Este artigo tem por objetivo descrever a produção científica na área de Educação Especial sobre o atendimento educacional à faixa etária de zero a três anos, fase inicial da Educação Infantil, nos últimos 25 anos. Utiliza-se como fonte de busca as bases de dados Scientific Electronic Library Online (SciELO), Periódicos Eletrônicos em Psicologia (Pepsic), Portal de Periódicos Capes/MEC; Biblioteca Digital Brasileira de Teses e Dissertações (BDTD); Red de Revistas Científicas da América Latina Y el Caribe, España y Portugal (Redalyc) e, como descritores, os termos "educação especial", "educação inclusiva", "inclusão" e "creche", no período de 1993 a 2017. Foram encontrados 25 trabalhos, dentre eles 17 teses e dissertações e oito artigos. Após leitura minuciosa dos objetivos, métodos e resultados, verificou-se que os temas políticas públicas de Educação Infantil e Educação Especial; creches inclusivas: relatos de casos; formação de profissionais e concepções sobre inclusão contemplam as discussões na área. A inclusão na creche ainda é incipiente, tanto nos documentos oficiais como na prática. No entanto, a formação dos profissionais para essa realidade influencia fortemente na percepção e nas concepções que eles têm das crianças e das atividades nos contextos educacionais. Desse modo, são importantes novos olhares sobre esses contextos, de forma a produzir materiais que possibilitem identificar fragilidades, experiências de sucesso, discussões relevantes que auxiliem na melhora da qualidade dos serviços oferecidos a essa faixa etária.

ABSTRACT: This paper aims to describe the scientific production in the Special Education area upon educational care offered to children aged from zero to three, initial stage of Early Childhood Education for the past 25 years. The database used as a search source were the Scientific Electronic Library Online (SciELO), Periódicos Eletrônicos em Psicologia (PEPSIC), Portal de Periódicos Capes/MEC; Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) and Red de Revistas Científicas da América Latina Y el Caribe, España y Portugal (REDALYC), and, as descriptors, the terms "educação especial" (special education), "educação inclusiva" (inclusive education),"inclusão" (inclusion) and "creche" (daycare facility ), from 1993 to 2017. Twenty five papers, among them seventeen doctoral dissertations and master's theses and eight papers. After a thorough reading of the objectives, methods and results, it was verified that the public policy themes of Early Childhood Education and Special Education; inclusive daycare facilities: case reports; education of professionals and conceptions about inclusion contemplate the discussions in the area. Inclusion in daycare is still incipient, both in official documents and in practice. However, the education of professionals for this reality strongly influences the perception and conceptions they have of children and activities in educational contexts. Therefore, new perspectives on these contexts are important, in order to produce materials that allow us to identify fragilities, successful experiences and relevant discussions that help to improve the quality of the services offered to that age group.

AbstractIntroduction: Communication is a fundamental element for the development of human beings, promoting their coexistence in society. However, changes in muscle tone, associated with cerebral palsy (CP), among other conditions, cause phono-articulatory dysfunctions hindering speech capabilities. Although there are resources for augmentative and alternative communication (AAC), most of them do not completely satisfy the needs of individuals with motor impairment. Therefore, this study proposes a tool based on mobile technology for AAC, which can be adapted to the characteristics of the motor limitations of CP users. Methods Mobile system development was conducted employing user-centered design and development methods. Functions were developed allowing the communication of phrases through pictographic resources and a mechanism of speech synthesis, that can be customized according to specific communication needs. To validate this system, 20 CP volunteers with speech difficulties and motor impairment were recruited from two institutions in the State of São Paulo, Brazil. They operated the system following a pre-defined test protocol, and they answered a system usability scale (SUS) questionnaire, to rate the ease of learning, memorization, efficiency, occurrence of runtime errors, and the level of user satisfaction. Results The results showed a score of 85.85 ± 2.28 above the average SUS scale, for each one of the quality components assessed by the volunteers. Conclusion The developed software is user-friendly, representing a new option for AAC, and is customized according to the communication needs of people with speech disorder and motor impairment.
