Abstract This article presents a formulation for the optimization problem that minimizes the CO2 emission of pile caps with variations of geometry and pile position. The problem is defined by the design variables: concrete pile cap dimensions, rebar ratio, concrete compressive strength, the number of piles, the diameter, and length. The environmental impact was chosen as the objective function, taking CO2 emission as the main parameter. The design procedure was based on the ABNT NBR 6118:2014 (2014), and by the formulation proposed by Blévot & Frémy (1967). Also, the soil structure interaction between the cap and the piles was considered in the optimization problem. The problem was implemented using MATLAB (2016) and solved via a Genetic Algorithm native to the program. Results obtained from numerical examples were compared with structural designs solutions located in the Grande Vitória metropolitan area, Espírito Santo, Brazil and validated with a commercial software. The analyses indicate that design optimizations of pile caps considering the compressive strength of concrete, the diameter and length of piles and the optimal geometry of the pile caps may lead to significant reductions of material consumption, and consequently, a reduction of environmental impacts.

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.

ABSTRACT Introduction: The Pilates method (PM) combines slow-deep breathing with strengthening and stretching exercises. However, it has been proposed as a method of physical conditioning for several decades and only recently aroused academic/scientific interest, with few reports of the effects of this intervention in hypertensive patients. Objective: to compare PM to aerobic training (AT) effects on hypertensive subjects’ blood pressure (BP), functional capacity and autonomic balance. Methods: Twenty-four hypertensive subjects were randomly allocated into two groups: ATG performed three 40 min sessions/week, moderate intensity (40-70% of reserve HR), and PMG performed two 60 min sessions/week; both during the same eight weeks period. Blood pressure (casual and for 24 hours), 6-minute walking test (6-MWT) and autonomic balance were evaluated before and after intervention. Results: There was a reduction on systolic BP (SBP, p=0.007), diastolic (p=0.032) and mean blood pressure (MBP, p=0.016), measured on 24h, on PMG. There was also a 24h SBP reduction on ATG (p=0.021). The PMG had a greater reduction on 24h SBP (-3.4 mmHg, 95% CI -6.6 to -0.2) and MBP (-3.3 mmHg, 95% CI -6.3 to -0.3) than the ATG. ATG held a longer distance in 6-MWT. Casual BP and autonomic balance had no difference. Conclusion: This PM protocol was superior to AT on BP monitored for 24 hours in hypertensive subjects, but AT was better for functional capacity. The eight weeks of training were not enough to change the autonomic balance. Level of Evidence: I; High-quality randomized clinical trial with or without statistically significant difference, but with narrow confidence intervals.

RESUMEN Introducción: el método Pilates (MP) combina la respiración lenta-profunda con ejercicios de fortalecimiento y estiramiento. Aunque se ha propuesto como un método de acondicionamiento físico durante varias décadas, solo recientemente despertó interés académico/científico, con pocos reportes de los efectos de esta intervención en pacientes hipertensos. Objetivo: comparar los efectos del MP con el entrenamiento aeróbico (EA) sobre la presión arterial (PA), la capacidad funcional y el equilibrio autónomo en sujetos hipertensos. Métodos: Veinticuatro sujetos hipertensos fueron asignados aleatoriamente en dos grupos: GEA realizó tres sesiones de 40 min/semana, intensidad moderada (40-70% de la FC de reserva), y GMP realizó dos sesiones de 60 min/semana; ambos durante el mismo período de 8 semanas. La presión arterial (casual y durante 24 horas), la prueba de marcha de 6 minutos y el equilibrio autonómico se evaluaron antes y después de la intervención. Resultados: Hubo una reducción de la PA sistólica (PAS, p = 0,007), diastólica (p = 0,032) y presión arterial media (PAM, p = 0,016), medida a las 24 h, en GMP. También hubo una reducción de PAS en 24 h en GEA (p = 0,021). El GMP tuvo una mayor reducción en la PAS de 24 h (-3,4 mmHg, CI del 95%: -6,6 a -0,2) y la PAM (-3,3 mmHg, CI del 95%: -6,3 a -0,3) que la GEA. GEA mantuvo una mayor distancia en la prueba de marcha de 6 minutos. La PA casual y el equilibrio autónomo no tuvieron diferencias. Conclusión: Este protocolo de MP fue superior al EA en la PA monitoreada durante 24 horas en sujetos hipertensos, pero el EA fue mejor para la capacidad funcional. Las ocho semanas de entrenamiento no fueron suficientes para cambiar el equilibrio autonómico. Nivel de Evidencia: I; Estudio clínico aleatorizado de alta calidad con o sin diferencia estadísticamente significativa, pero con intervalos de confianza estrechos.

RESUMO Introdução: O método Pilates (MP) combina respiração lenta e profunda com exercícios de fortalecimento e alongamento. Embora tenha sido proposto como método de condicionamento físico por várias décadas, só recentemente despertou-se o interesse acadêmico/científico, com poucos relatos dos efeitos dessa intervenção em hipertensos. Objetivos: comparar os efeitos do MP com o treinamento aeróbio (TA) sobre a pressão arterial (PA), capacidade funcional e equilíbrio autonômico em hipertensos. Métodos: Vinte e quatro hipertensos foram alocados aleatoriamente em dois grupos: O grupo GTA realizou três sessões de 40 min/semana, intensidade moderada (40-70% da FC de reserva), e o grupo GMP, que realizou duas sessões de 60 min/semana; ambos durante o mesmo período de 8 semanas. A pressão arterial (casual e após 24 horas), o teste de caminhada de 6 minutos (TC6) e o equilíbrio autonômico foram avaliados antes e depois da intervenção. Resultados: Houve redução da PA sistólica (PAS, p = 0,007), diastólica (p = 0,032) e da pressão arterial média (PAM, p = 0,016), medida em 24h, sem GMP. Também houve redução da PAS em 24h no GTA (p = 0,021). O GMP teve uma redução maior em 24h PAS (-3,4 mmHg, IC 95% -6,6 a -0,2) e PAM (-3,3 mmHg, IC 95% -6,3 a -0,3) do que o GTA. O GTA manteve uma maior distância no TC6. A PA casual e o equilíbrio autonômico não apresentaram diferenças estatísticas. Conclusão: Este protocolo de MP foi superior ao TA na PA monitorada por 24 horas em hipertensos, porém o TA foi superior para a capacidade funcional. As oito semanas de treinamento não foram suficientes para alterar o equilíbrio autonômico. Nível de Evidência: 1; Estudo clínico randomizado de alta qualidade com ou sem diferença estatisticamente significativa, mas com intervalos de confiança estreitos.

ABSTRACT Management of Quilombola systems are primitive agricultural systems based on the ancestral knowledge of Afro-Brazilian enslaved people. Here, the aim was to understand the impact of these primitive farming methods on the distribution of available nitrogen (N) forms in the soil profile of two Brazilian Cerrado phytophysiognomies. The soil was sampled in Cerradão (high Cerrado) and Cerrado Stricto sensu (low Cerrado) at six soil depths (0-10, 10-20, 20-30, 30-40, 40-50, and 50-60 cm). The following management systems were considered: pasture (PP1 and PP2), maize cultivation (M1 and M2), citrus-cassava intercropping (T1), and citrus monoculture (T2). In addition, the soil was sampled in the native area of Cerradão (NC1) and Cerrado Stricto sensu (NC2). Three N forms were determined: i) available nitrogen (Av-N), ii) ammonium (NH4+-N) and iii) nitrate (NO3–-N) contents. The Av-N content decreased with increasing soil depth only in NC1 and NC2. The NO3–-N content was similar at all soil depths for maize and pasture, while the content decreased at soil depth for NC1, NC2, and T1. NH4+-N was similar in M2 and PP2, but it increased in T2, ranging from 6.17 mg kg–1 to 17.54 mg kg–1. Overall, the dynamics of available N forms varied according to the Cerrado phytophysiognomy and the management systems and NO3–-N was the most constant N form in the soil profile. Therefore, although the management of Quilombola systems is less intensive, they negatively affect the dynamics and N availability, mainly where management is less conservative, that is, in maize and citrus monocultures.

ABSTRACT Objective: To analyze the compliance with the commercialization of children's products included in the Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-Related Products (NBCAL) in drugstores in Uberlândia/MG. Methods: A cross-sectional study was carried out in 143 drugstores that sold infant products: infant formula (IF), follow-up IF, nipples, teats, pacifiers and nipple shields; FI for young children, transition foods and cereal-based foods, fluid or powdered milk, modified/similar milks of plant origin and dairy compounds. The location of drugstores in the five geographic sectors was performed by geoprocessing. The data collected were: types of promotion and types of drugstore administration (drugstore chains/drugstores with independent administration). Irregular commercial promotion was expressed as absolute and relative frequencies. Results: Irregular commercial promotion was found in 11.7% of nipples, pacifiers and bottles, in 10.0% of IF and follow-up formula, in 9.5% of IF for young children, in 11.1% fluid or powdered milk, in 25.0% of transition foods and cereal-based foods and in 59.1% of dairy compounds. In commercial drugstore chains, the presence of promotion for dairy (81.8 vs. 28.6%, respectively) was higher than in drugstores with independent administration. The opposite ocurred for fluid or powdered milk, modified and similar milks of plant origin. The downtown and eastern sectors had the highest percentages of promotions (26%). Conclusions: NBCAL violations still occur in drugstores, mainly in the sale of young children's foods and in the commercial network drugstores.

RESUMO Objetivo: Analisar a conformidade da comercialização dos produtos infantis incluídos na Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeira (NBCAL) e de compostos lácteos em drogarias de Uberlândia/MG. Métodos: Estudo transversal realizado em 143 drogarias que vendiam produtos infantis: fórmulas infantis (FI) para lactentes, FI de seguimento para lactentes, mamadeiras, bicos, chupetas e protetores de mamilo; FI para crianças de primeira infância, alimentos de transição e alimentos à base de cereais, leites fluidos/em pó, leites modificados/similares de origem vegetal e composto lácteo. A localização das drogarias nos cinco setores geográficos foi realizada por geoprocessamento. Os dados coletados foram: tipos de promoção comercial irregular e tipo de administração da drogaria (rede/independente). As promoções comerciais irregulares foram expressas em frequências absoluta e relativa. Resultados: Verificamos a presença de promoção comercial irregular em 11,7% dos bicos, chupetas e mamadeiras, em 10,0% das FI lactentes/seguimento de lactentes, em 9,5% das FI para crianças de primeira infância, em 11,1% dos leites, em 25,0% de alimentos de transição e em 59,1% dos compostos lácteos. Nas drogarias de rede, a presença de promoção comercial irregular foi maior para compostos lácteos (81,8 vs. 28,6%, respectivamente) e, para leites, foi maior nas drogarias independentes (30,8 vs. 6,0%). Os setores central e leste apresentaram os maiores percentuais de promoção comercial irregular (26%). Conclusões: As violações à NBCAL ainda ocorrem nas drogarias, principalmente para os produtos destinados às crianças de primeira infância, e nas drogarias de rede.

ABSTRACT Overcoming malnutrition in all its forms, which is also manifested in the obesity epidemic, is one of the priorities of the 2030 Agenda and the Sustainable Development Goals. This article presents reflections on food insecurity in Brazil, based on topics such as population growth, climate change, biodiversity and traditional and regenerative food systems; it also addresses the role of social initiatives to guarantee the Human Right to Adequate Food. The Nutrition and Poverty Research Group, Planetary Health - Brazil Group, and the Center for Artificial Intelligence (C4AI) - AgriBio Axis, assume that the organized and systemic resumption of the initiatives mentioned out in this position paper can contribute to the articulation between research, public policies and services, to combat all forms of malnutrition, as a complex and priority problem to ensure social welfare.

RESUMO O combate à má alimentação em todas as suas formas, que também se expressa na epidemia da obesidade, é uma das prioridades da Agenda 2030 e dos Objetivos de Desenvolvimento Sustentável. Este artigo traz elementos sobre insegurança alimentar no Brasil, a partir de temas relativos ao crescimento populacional, mudanças climáticas, biodiversidade e sistemas alimentares tradicionais e regenerativos; trata também do papel dos movimentos sociais para a garantia do Direito Humano à Alimentação Adequada. O Grupo de Pesquisa em Nutrição e Pobreza, o Saúde Planetária Brasil, e o Centro de Inteligência Artificial (C4AI) - Eixo AgriBio, entendem que a retomada organizada e sistêmica das frentes apontadas neste artigo de posicionamento, pode constituir um caminho para a articulação entre pesquisa, serviço e políticas públicas na direção do combate à fome e às demais manifestações da má alimentação, enquanto problema complexo prioritário para a garantia do bem-estar social.

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.

Resumo O artigo investiga a correlação entre engajamento e qualidade de vida no trabalho dos profissionais de enfermagem de um hospital público do interior do estado de São Paulo, no início da pandemia de COVID-19. Estudo transversal, descritivo e correlacional, com profissionais de enfermagem, realizado entre dezembro de 2020 e janeiro de 2021. Foram utilizadas as versões brasileiras da Utrecht Work Engagement Scale (UWES) e da Escala de Avaliação da Qualidade de Vida no Trabalho (QVT), segundo modelo de Walton. Os profissionais de enfermagem apresentaram correlação forte e positiva (r≥0.70) entre o domínio integração social da QVT e a dimensão vigor da UWES (r=0,88; p=<0,001); correlação positiva moderada (r≥0.40≤0.69) entre as condições de trabalho (QVT) e as dimensões vigor (r=0,40; p=<0,001), dedicação (r=0,40; p=<0,001) e escore geral (r=0,41; p=<0,001) da UWES. As correlações foram positivas e fracas (r≤0.39) para os demais domínios da QVT e as dimensões da UWES. Concluiu-se que os profissionais com níveis satisfatórios de qualidade de vida tendem a ter níveis mais altos de engajamento no trabalho. No início da pandemia de COVID-19, os profissionais de enfermagem estavam fortemente engajados e satisfeitos com sua qualidade de vida no trabalho.

Abstract This article investigates the correlation between work engagement and work-related quality of life among nursing staff at a public hospital in São Paulo State, at the onset of the COVID-19 pandemic. A descriptive, correlational, cross-sectional study of nursing personnel was conducted from December 2020 to January 2021, using the Brazilian versions of the Work & Well-being Survey (Utrecht Work Engagement Scale - UWES) and the Work-related Quality of Life (WRQoL) scale, following Walton’s model. Nursing staffs returned a strong positive correlation (r≥0.70) between the social integration domain of the WRQoL and the vigour dimension of the UWES (r=0.88; p=<0.001); a moderate positive correlation (r≥0.40≤0.69) between working conditions (WRQOL) and the vigour (r=0.40; p<0.001), dedication (r=0.40; p<0.001) and overall score (r=0.41; p<0.001) dimensions of the UWES. Correlations were positive and weak (r≤0.39) for the other WRQoL domains and the UWES dimensions. It was concluded that personnel with satisfactory levels of quality of life tend to show higher levels of engagement at work. At the onset of the COVID-19 pandemic, nursing professionals were strongly engaged and satisfied with their work-related quality of life.

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: En | Text: En | PDF: En

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.
