Abstract A continuous increase in levels of atmospheric pollution and emission restrictions has forced scientists and engineers to adopt new strategies to improve and develop internal combustion engines. One strategy is based on the development of new simulation methodologies using computational fluid dynamic (CFD) techniques, proposed in the present article. In this study,the dynamic loop methodology with ANSYS Fluent code is proposed to perform the numerical simulation ofa four-stroke spark ignition engine. The complexity of the real case was first simplified with three-dimensional CAD geometry, which was then discretized in ANSYS Meshing, whereby a hybrid mesh was created using prismatic and tetrahedral elements. Simulations for in-cylinder analyses were performed in cold flow and employing common flow parameters, such as swirl and tumble. The mesh quality results were classified as good or excellent, being higher than 0.79 for orthogonal quality criteria and lower than 0.36 for skewness criteria. Turbulent effects were introduced concerning the opening and closing of the valves. It was found that the turbulence increases during the intake stroke up to 90°, and during the power stroke, wherein the of the piston bowl, had a great contributionthat can be seen from the swirl and tumble profile for the engine cycle. In the case of the turbulence intensity, a sharp increase was registered during the admission step up to 90°, at which point the turbulence intensity was 4.0. It canbe concluded that this is an innovative approach, capable of simulating the engine motion profile in cold flow.

RESUMO O artigo reflete sobre a qualidade e a avaliação educacional no Brasil e na Venezuela, sobre as aproximações e os distanciamentos entre esses países, além de situar diferentes concepções de qualidade da educação no campo e sua relação com a construção de processos e de práticas educativas na perspectiva da formação integral dos sujeitos. Os marcos regulatórios de avaliação desses países nos levaram ao pressuposto de que as avaliações que induzem escolas a se autoavaliarem podem se constituir em instrumentos para produção de melhoria da educação pública, na perspectiva da qualidade social. Venezuela sujeitos pública social

ABSTRACT This article reflects on quality and educational assessment in Brazil and Venezuela and its focus is on the similarities and differences between these countries. In addition it also aims at different conceptions of rural education quality and its relationship within the building of educational processes and educational practices under the perspective of the integral training of the subjects involved. The assessment regulatory frameworks in these countries led us to the assumption that assessments that induce schools to self-assess can become tools for producing improvements in public education, under the perspective of social quality. involved selfassess self assess

Resumo O artigo analisou o processo de precarização das relações de trabalho no setor da saúde, demonstrando como essa situação gerou sofrimento dos trabalhadores. O texto buscou registrar como a adoção institucional das concepções econômicas neoliberais, de redução das políticas sociais de Estado, acopladas a um histórico de rejeição cultural aos direitos trabalhistas, proporcionou a atração dos mecanismos de precarização do trabalho, notadamente, a terceirização da mão de obra e da prestação de serviços. No segundo momento, o texto aponta as impropriedades jurídicas cometidas, apresentando as consequências da fragilização do vínculo jurídico nas condições de trabalho desses trabalhadores, principalmente no que se refere às jornadas de trabalho e a remuneração, destacando-se, também, o quanto a disseminação desses vínculos representou um fator de rebaixamento geral dos salários e direitos trabalhistas e previdenciários no setor. Foram apresentados, ainda, dados das pesquisas da Fiocruz sobre condições de trabalho durante a pandemia. Conclui mostrando a urgência de se resgatarem os institutos jurídicos trabalhistas que foram abandonados no percurso histórico estudado, para direcionar a novo rumo as políticas públicas na saúde.

Abstract The present article analyzed the process of precarious work relations in the health sector, demonstrating how this situation generated illness and suffering among workers. The text sought to register how the institutional adoption of neoliberal economic conceptions, of the reduction of State social policies, coupled with a history of cultural rejection of labor rights, provided the attraction of mechanisms of precarious work for the public sector, notably, the outsourcing of labor and the provision of services. In a second moment, the text points out the legal improprieties committed, presenting the consequences of the weakening of the legal bond in the working conditions of these workers, mainly regarding working hours and remuneration, also highlighting how much the dissemination of these links represented a factor of a general reduction in wages and labor and social security rights in the sector. Data from Fiocruz surveys on working conditions during the pandemic were also presented. The article concludes by showing the urgency of rescuing the legal labor institutes that were abandoned in the historical path studied in order to guide the public health policies in a new direction.

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

ABSTRACT Background: Critical illness is a major ongoing health care burden worldwide and is associated with high mortality rates. Sodium-glucose cotransporter-2 inhibitors have consistently shown benefits in cardiovascular and renal outcomes. The effects of sodium-glucose cotransporter-2 inhibitors in acute illness have not been properly investigated. Methods: DEFENDER is an investigator-initiated, multicenter, randomized, open-label trial designed to evaluate the efficacy and safety of dapagliflozin in 500 adult participants with acute organ dysfunction who are hospitalized in the intensive care unit. Eligible participants will be randomized 1:1 to receive dapagliflozin 10mg plus standard of care for up to 14 days or standard of care alone. The primary outcome is a hierarchical composite of hospital mortality, initiation of kidney replacement therapy, and intensive care unit length of stay, up to 28 days. Safety will be strictly monitored throughout the study. Conclusion: DEFENDER is the first study designed to investigate the use of a sodium-glucose cotransporter-2 inhibitor in general intensive care unit patients with acute organ dysfunction. It will provide relevant information on the use of drugs of this promising class in critically ill patients. ClinicalTrials.gov registry: NCT05558098

RESUMO Antecedentes: A doença crítica é um importante ônus permanente da assistência médica em todo o mundo e está associada a altas taxas de mortalidade. Os inibidores do cotransportador de sódio-glicose do tipo 2 têm demonstrado consistentemente benefícios nos desfechos cardiovasculares e renais. Os efeitos dos inibidores do cotransportador de sódio-glicose do tipo 2 em doenças agudas ainda não foram devidamente investigados. Métodos: O DEFENDER é um estudo de iniciativa do investigador, multicêntrico, randomizado, aberto, desenhado para avaliar a eficácia e a segurança da dapagliflozina em 500 participantes adultos com disfunção orgânica aguda hospitalizados na unidade de terapia intensiva. Os participantes aptos serão randomizados 1:1 para receber 10mg de dapagliflozina e o tratamento padrão por até 14 dias ou apenas o tratamento padrão. O desfecho primário é um composto hierárquico de mortalidade hospitalar, início de terapia renal substitutiva e tempo de internação na unidade de terapia intensiva, até 28 dias. O monitoramento da segurança será rigoroso durante todo o estudo. Conclusão: O DEFENDER é o primeiro estudo desenvolvido para investigar o uso de um inibidor do cotransportador de sódio-glicose do tipo 2 em pacientes de unidade de terapia intensiva geral com disfunção orgânica aguda. O estudo fornecerá informações relevantes sobre o uso de medicamentos dessa classe promissora em pacientes críticos. Registro ClincalTrials.gov: NCT05558098

Abstract The spectrum of neuropsychiatric phenomena observed in amyotrophic lateral sclerosis (ALS) is wide and not fully understood. Disorders of laughter and crying stand among the most common manifestations. The aim of this study is to report the results of an educational consensus organized by the Brazilian Academy of Neurology to evaluate the definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in ALS patients. Twelve members of the Brazilian Academy of Neurology - considered to be experts in the field - were recruited to answer 12 questions about the subject. After exchanging revisions, a first draft was prepared. A face-to-face meeting was held in Fortaleza, Brazil on 9.23.22 to discuss it. The revised version was subsequently emailed to all members of the ALS Scientific Department from the Brazilian Academy of Neurology and the final revised version submitted for publication. The prevalence of pseudobulbar affect/pathological laughter and crying (PBA/PLC) in ALS patients from 15 combined studies and 3906 patients was 27.4% (N = 1070), ranging from 11.4% to 71%. Bulbar onset is a risk factor but there are limited studies evaluating the differences in prevalence among the different motor neuron diseases subtypes, including patients with and without frontotemporal dementia. Antidepressants and a combination of dextromethorphan and quinidine (not available in Brazil) are possible therapeutic options. This group of panelists acknowledge the multiple gaps in the current literature and reinforces the need for further studies.

Resumo O espectro de fenômenos neuropsiquiátricos observados na ELA é amplo e não completamente entendido. Desordens do riso e do choro estão entre as manifestações mais comuns. O objetivo deste estudo é relatar os resultados de um Consenso organizado pela Academia Brasileira de Neurologia para avaliar definições, fenomenologia, diagnóstico, e manejo dos distúrbios do riso e do choro em pacientes com ELA. Doze membros da Academia Brasileira de Neurologia – considerados experts na área – foram recrutados para responder 12 questões na temática. Depois da verificação das revisões, um primeiro manuscrito foi preparado. Após, foi realizado um encontro presencial em Fortaleza, Brasil, em 23/09/2022, para discussão do conteúdo. A versão revisada foi posteriormente enviada por e-mail para todos os membros do Departamento Científico de DNM/ELA da Academia Brasileira de Neurologia e a versão final revisada foi submetida para publicação. A prevalência da síndrome pseudobulbar em pacientes com ELA em 15 estudos combinados com 3906 pacientes foi de 27,4% (n = 1070), variando entre 11,4% e 71%. Início bulbar é um fator de risco, mas há limitados estudos avaliando as diferenças em prevalência entre os diferentes subtipos de Doença do Neurônio Motor, incluindo pacientes com e sem Demência Frontotemporal. Antidepressivos e uma combinação de dextrometorfana e quinidina (indisponíveis no Brasil) são opções terapêuticas possíveis. Esse grupo de panelistas reconhece as múltiplas demandas não atendidas na literatura atual e reforça a necessidade de futuros estudos.

SUMMARY: The COVID-19 pandemic caused several changes in the teaching of human anatomy, among them the use of different teaching methodologies based on E-learning. However, studies evaluating electronic tools have not provided clear evidence of effective student learning. Thus, this was the first study to evaluate medical students after completing human anatomy courses in the E- learning modality. We recruited first term (Group A, n=25) and second term (Group B, n=13) medical students. We applied a practical assessment based on 50 human anatomy markingson real anatomical specimens and cadavers, to be completed in Questionnaire 01 (Phase I). After detecting low scores on Questionnaire 01 by both groups, we applied a practical and face-to-face tutoring system for 14 days (Phase II). Afterwards, we re-evaluated both groups by repeating the same scores (Questionnaire 02, Phase III). According to the paired analysis of questionnaires 01 and 02 by Student's T-test, both groups showed significant increase in the final scores obtained in questionnaire 02 (Phase III). The evidence showed that the remote format lecture system weakened the learning and retention process of basic anatomical knowledge by medical students. On the other hand, in-person practical teaching proved to be efficient in the formative process of the students, a fact proven by the significant increase in the scores of the students in the 02 questionnaire, for both groups.

RESUMEN: La pandemia por COVID-19 provocó varios cambios en la enseñanza de la anatomía humana, entre ellos el uso de diferentes metodologías de enseñanza basadas en E-learning. Sin embargo, los estudios que evalúan las herramientas electrónicas no han proporcionado evidencia clara de un aprendizaje efectivo de los estudiantes. Este fue el primer estudio que evaluó a estudiantes de medicina luego de cursar cursos de anatomía humana en la modalidad E-learning. Reclutamos estudiantes de medicina de primer término (Grupo A, n=25) y segundo término (Grupo B, n=13). Se aplicó una evaluación práctica basada en 50 marcas de anatomía humana sobre especímenes anatómicos reales y cadáveres, para ser completado en el Cuestionario 01 (Fase I). Tras detectar puntuaciones bajas en el Cuestionario 01 por parte de ambos grupos, se aplicó un sistema de tutorías prácticas y presenciales durante 14 días (Fase II). Posteriormente, reevaluamos ambos grupos repitiendo las mismas puntuaciones (Cuestionario 02, Fase III). Según el análisis apareado de los cuestionarios 01 y 02 por la prueba T de Student, ambos grupos mostraron aumento significativo en los puntajes finales obtenidos en el cuestionario 02 (Fase III). La evidencia mostró que el sistema de conferencias en formato remoto debilitó el proceso de aprendizaje y retención de conocimientos anatómicos básicos por parte de los estudiantes de medicina. Por otro lado, la docencia práctica presencial demostró ser eficiente en el proceso formativo de los alumnos, hecho que demuestra el aumento significativo de las puntuaciones de los alumnos en el cuestionario 02, para ambos grupos.

ABSTRACT Understorey herbs form a diverse and understudied plant assemblage in tropical forests. Although several studies and research teams have long been dedicated to the study of this conspicuous vegetation component in Amazonia, no effort to unify the data has been undertaken to date. In contrast to trees and other life forms for which major data compilations already exist, a unified database dedicated to herbs is still lacking. Part of the problem is in defining what is a herb and how to effectively sample herb assemblages. In this article, we describe the database HERBase, an exhaustive compilation of published and unpublished data on herb inventories in Amazonia. We also describe the structure, functioning, and guidelines for data curation and integration in HERBase. We were able to compile information from 1381 plots from all six Amazonian geographic regions. Based on this dataset, we describe and discuss sampling and knowledge gaps, priority areas for new collections, and recommend sampling protocols to facilitate data integration in the future. This novel database provides a unique biodiversity data repository on understorey herbs that will enable new studies on community ecology and biogeography.

RESUMO As ervas do sub-bosque formam um componente diversificado e pouco estudado em florestas tropicais. Embora vários estudos e grupos de pesquisa tenham se dedicado ao estudo desse componente conspícuo na Amazônia, nenhum esforço foi feito até o momento para unificar essas informações. Em contraste com árvores e outros grupos de plantas para os quais já existem grandes compilações de dados, uma base de dados unificada dedicada às ervas ainda não existe. Parte do problema está em definir o que é uma erva e como amostrar comunidados de ervas de forma eficiente. Neste artigo descrevemos a base de dados HERBase, uma compilação exaustiva de dados publicados e não publicados sobre inventários de ervas na Amazônia. Também descrevemos a estrutura, funcionamento e diretrizes para curadoria e integração de dados na HERBase. Conseguimos compilar informações de 1381 parcelas de todas as seis regiões geográficas amazônicas. Com base nesses dados, descrevemos e discutimos lacunas de amostragem e conhecimento, apontamos áreas prioritárias para novas coletas e recomendamos protocolos de amostragem para facilitar a integração de dados no futuro. Essa nova base de dados fornece dados únicos de biodiversidade sobre ervas do sub-bosque que permitirão novos estudos sobre ecologia e biogeografia de comunidades.

Abstract This paper presents a study of a segmented waveguide where the layers are distributed following the Fibonacci sequence and aims to diminish the scattering losses usually caused by imperfections in the core boundaries of the waveguide. This phenomenon normally happens in structures which present a high contrast between the refractive index of the core and the refractive index of the clad. The analyses were obtained through observations of wave fields that propagates along the waveguide, how the effective refractive index (neff) varies along the z-direction and the study of its normalized power. The simulation of this photonic component was accomplished with the help of the Vectorial Beam Propagation Method (VBPM).

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17–4.21), intensive care unit admission (OR 2.00 CI 1.07–3.74), and desaturation at admission (OR 3.72 CI 1.41–9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups. Conclusion Brazilian Black women were more likely to die due to the consequences of COVID-19.

Resumo Objetivo Avaliar o impacto da raça (negra versus não negra) nos desfechos maternos e perinatais de gestantes com COVID-19 no Brasil. Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17–4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07–3,74) e dessaturação na admissão (OR 3,72 CI 1,41–9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos. Conclusão Mulheres negras brasileiras tiveram maior probabilidade de morrer devido às consequências da COVID-19.

Abstract Objective: This study aimed to investigate non-alcoholic fatty liver disease (NAFLD) occurrence and factors associated with the disease in phenylketonuria (PKU) patients undergoing exclusive dietary treatment. Method: This cross-sectional study included 101 adolescents 10 to < 20 years of age with PKU, who were undergoing exclusive dietary treatment and monitored since early diagnosis at a single reference service. Anthropometric and biochemical assessments were performed and food intake was documented, and an ultrasound diagnosis of NAFLD was established. Data were evaluated using the Student’s t-test for continuous variables, the chi-square for categorical variables, and logistic regression using the Wald chi-squared test; differences with p < 0.05 were considered to be statistically significant. Results: NAFLD was detected in 26 (25.7%) teenagers. There was no difference in prevalence between the sexes or nutritional status. The final logistic regression model revealed low sensitivity (26.1%) and high specificity (94.7%). The specificity suggested a lower likelihood of NAFLD in older adolescents, in the presence of normal or high levels of alkaline phosphatase, lower carbohydrate intake, and adequate protein and lipid intake. Conclusions: The prevalence of NAFLD in adolescents with PKU was higher than that found in healthy Brazilian adolescents and similar to that found in obese Brazilian children, suggesting a higher risk for NAFLD in patients with PKU treated exclusively by dietary modification.

Abstract Objective: This article aims to review the literature regarding the use of technologies to promote mental health for pregnant women. We seek to: understand the strategies that pregnant women use for mental health care. Also, we investigate the existence of scientific evidence that validates such practices. Methods: This study follows the PRISMA guidelines for systematic reviews. We analyze 27 studies published between 2012 and 2019. We include publications in Portuguese, English, and Spanish. Results: The results revealed several different possibilities to use technology, including the use of text messages and mobile applications on smartphones. Mobile applications are the most commonly used approaches (22.5%). Regarding the strategies used, cognitive-behavioral approaches, including mood checks, relaxation exercises, and psychoeducation comprised 44.12% of the content. Conclusion: There is a need for further investigation and research and development efforts in this field to better understand the possibilities of intervention in mental health in the digital age.

Abstract: En | Text: En | PDF: En

ABSTRACT The objectives of this work were to use Sesuvium verrucosum to produce stable and mature compost and vermicompost and to evaluate their influence on the growth and production parameters of the Solanum lycopersicum L. crop. For the preparation of vermicompost, the earthworm Eisenia fetida (Savigny) was used. The proposed treatments were: T1 (negative control) [no organic fertilizer + urea], T2 (positive control) [bovine manure (100%) + urea], T3 (compost) [bovine manure (100%) + urea], T4 (compost) [S. verrucosum (25%) + bovine manure (75%) + urea], T5 (compost) [S. verrucosum (50%) + bovine manure (50%) + urea], T6 (compost) [S. verrucosum (75%) + bovine manure (25%) + urea], T7 (vermicompost) [bovine manure (100%) + urea], and T8 (vermicompost) [S. verrucosum (25%) + bovine manure (75%) + urea]. The results showed that all the treatments were stable, mature and rich in nutrients after 140 days. In general, treatments made from S. verrucosum showed a high pH (7.97–8.45) and electrical conductivity (3.83–8.85 dS m-1). Nonetheless, excluding T7, the treatments made from a proportion of 25% halophyte and 75% bovine manure (T8 and T4) achieved the highest morphological parameters in the different variables that were evaluated, as well as the highest yields compared to controls T1 and T2, followed by T3, T5 and T6, respectively. Therefore, it was concluded that S. verrucosum can serve as a stable and mature organic amendment, rich in nutrients, and that can be used to improve the growth and development of the S. lycopersicum crop.
