Abstract This study aimed to identify the influence of replacing coarse natural aggregate with coarse recycled concrete aggregate on the thickness and volume of the cementitious paste under the variation of the water/cement ratio in the fresh and hardened properties of pervious concrete. The determined theoretical paste thickness was inefficient for pervious concrete dosage. However, it was found that the paste volume was the parameter that was best related to the mechanical and permeability properties of the studied material. Pervious concrete with natural aggregates showed higher compressive strength than concrete with recycled aggregates, although both met the regulations. All the concretes produced, except one with recycled aggregate of w/c ratio 0.25, reached the tensile strength in the minimum design bending. Pervious concrete with recycled aggregates showed more significant mass loss by abrasion and more porosity than concretes with natural aggregates. Finally, all pervious concretes presented permeability coefficients greater than the lower limit determined by the standard.

Resumo Este estudo teve como objetivo identificar a influência da substituição do agregado graúdo natural por agregado graúdo reciclado de concreto na espessura e no volume da pasta cimentícia sob a variação da relação água/cimento nas propriedades frescas e endurecidas do concreto permeável. A espessura teórica da pasta determinada foi ineficiente para dosagem de concreto permeável. Porém, constatou-se que o volume da pasta foi o parâmetro que melhor se relacionou com as propriedades mecânicas e de permeabilidade do material estudado. O concreto permeável com agregados naturais apresentou maior resistência à compressão que o concreto com agregados reciclados, mas ambos atenderam às normas vigentes. Todos os concretos produzidos, exceto com agregado reciclado de relação a/c 0,25, atingiram a resistência à tração na flexão mínima de projeto. O concreto permeável com agregados reciclados apresentou perda de massa mais significativa por abrasão e foi mais poroso que o concreto com agregados naturais. Por fim, todos os concretos permeáveis apresentaram coeficientes de permeabilidade superiores ao limite inferior determinado pela norma.

Resumo A avaliação do atraso de colheita de sementes de soja pode auxiliar na seleção de cultivares mais resistentes à deterioração no campo. O objetivo deste trabalho foi avaliar a qualidade fisiológica e sanitária de sementes de três cultivares de soja, submetidas ao atraso da colheita. Sementes das cultivares ‘NS 5959’, ‘BMX Potência’ e ‘TMG 1175’ foram colhidas em quatro épocas (R8; R8 + 10 dias; R8 + 20 dias e R8 + 30 dias) e avaliadas quanto ao grau de umidade, germinação, emergência, crescimento de plântulas e incidência de fungos. Houve redução na germinação e vigor das sementes das diferentes cultivares de soja, principalmente quando colhidas em R8 + 20 e R8 + 30 dias, devido à deterioração em campo. Além disso, o atraso na colheita proporcionou maior incidência de fungos nas sementes, principalmente Phomopsis sp., Aspergillus sp. e Cercospora kikuchii. Em geral, a cultivar ‘TMG 1175’ foi mais resistente à deterioração das sementes em campo causada pelo atraso de colheita.

Abstract The assessment of delayed harvesting of soybean seeds may help in the selection of cultivars more resistant to deterioration in the field. This work aimed to evaluate the physiological and sanitary quality of seeds of three soybean cultivars submitted to harvest delay. Seeds of the cultivars ‘NS 5959’, ‘BMX Potência’, and ‘TMG 1175’ were harvested in four periods (R8; R8 + 10 days; R8 + 20 days, and R8 + 30 days) and evaluated for the moisture content, germination, emergence, seedling growth, and fungal incidence. There was a reduction in germination and vigor of the seeds of the different soybean cultivars, especially when harvested at R8 + 20 and R8 + 30 days, due to deterioration in the field. In addition, the delay in harvest provided a higher incidence of fungi in the seeds, mainly Phomopsis sp., Aspergillus sp., and Cercospora kikuchii. In general, the cultivar ‘TMG 1175’ was more resistant to seed deterioration in the field caused by delayed harvesting.

Abstract Objective: to identify the sociodemographic profile and the characteristics of interpersonal violence against older adults during the first year of the COVID-19 pandemic in a capital city from the Brazilian Southeast region. Method: a descriptive and exploratory research study with a cross-sectional design based on the notifications of suspected or confirmed cases of violence against older adults between March 2020 and March 2021. A univariate statistical analysis and Fisher’s exact test (p<0.05) were performed. Results: a total of 2,681 notifications were recorded during the period. The main victims were individuals aged between 60 and 64 years old, female, white-skinned and with low schooling levels. The instances of violence were more frequent in the victims’ homes. Physical and psychological violence predominated, through physical force/beatings and threats, respectively. Most of the aggressors were male, younger than the victims and generally their children or intimate partners. The aggressions were perpetrated more than once and were driven by generational conflicts. There was low referral to entities for the protection of older adults. Conclusion: the sociodemographic profile found evidences vulnerable victims, subjected to many types of violence, and at a potential risk against their overall health.

Resumo Os padrões corporais ideais difundidos pelas redes sociais se destacam nos perfis fitness do Instagram. Poucos estudos de análise qualitativa avaliaram a motivação que leva as jovens seguidoras a acompanhar tais perfis e as repercussões que esses perfis têm na perceção e na satisfação com a autoimagem corporal. Portanto, o objetivo do presente estudo é avaliar tais desfechos. As entrevistas foram realizadas com estudantes universitárias que são seguidoras regulares de perfis fitness brasileiros no Instagram. Os dados foram submetidos à análise de conteúdo temática. As narrativas mostram que, atualmente, o corpo ideal feminino deve ser esguio, ter músculos esteticamente agradáveis e carência de traços masculinos. Essa forma corporal é vendida como fácil de ser alcançada por todos, desde que se tenha dedicação e força de vontade. As razões para seguir esses perfis se ancoram no incentivo e na inspiração que os blogueiros fornecem a seus seguidores. No entanto, as próprias seguidoras relatam sofrimento e frustração com a incapacidade de reproduzir o que pregam os perfis fitness. Conclui-se que seguidoras de perfis fitness do Instagram são influenciados pelo conteúdo destes perfis, que parecem (re)construir negativamente a percepção e satisfação com a autoimagem corporal.

Abstract The ideal body standards outspread by social media stands out in fitness Instagram profile. Only a few qualitative analysis studies have assessed the motivation that lead young women followers to follow such profiles and the repercussions that these profiles have on the perception and satisfaction of body self-image. Therefore, the objective of the present study is to evaluate such outcomes. Interviews were conducted with female undergraduate students who are regular followers of the Brazilian fitness Instagram profile. Data were subjected to thematic content analysis. Reports have shown that, nowadays, the female ideal body should be lean, have aesthetically pleasing muscles and lack of masculine features. Such body shape is sold as easily achievable by everyone as long as followers have dedication and willpower. Reasons for following such profiles lie on the encouragement and inspiration bloggers provide to their followers. However, the followers themselves suffer and are frustrated with their inability to reproduce what fitness profiles preachIt is concluded that followers of fitness profiles on Instagram are influenced by the content of these profiles, which seem to negatively (re)construct the perception and satisfaction with body self-image.

RESUMEN La enfermedad de Parkinson (EP) es el segundo trastorno neurodegenerativo más común después de la demencia tipo Alzheimer. Produce un declive significativo en la calidad de vida (CdV) de las personas que la sufren y sus familiares. Comprender los efectos físicos y psicosociales de esta enfermedad contribuye a la toma de decisiones clínicas. El presente estudio tiene como objetivo examinar la evidencia actual respecto al impacto de los trastornos fonoaudiológicos de origen motor sobre la CdV en personas con EP. Se realizó una revisión sistemática de la literatura buscando artículos en las siguientes bases de datos: PUBMED, SCIELO Y WoS, entre junio y julio del año 2020, con antigüedad máxima de 10 años, obteniendo una muestra de 10 trabajos. Las publicaciones analizadas describen aspectos de la CdV afectados en personas con EP con disfagia o disartria a través de cuestionarios. Los resultados indican un descenso en la CdV de las personas con EP en relación con su alimentación y comunicación, reportando fatiga al comer o hablar, vergüenza en actividades sociales, periodos extensos de alimentación, entre otros. Lo anterior pone de manifiesto la importancia de considerar como objetivos dentro de la intervención en EP componentes de la calidad de vida.

ABSTRACT Parkinson’s disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s-type dementia. It is known that these types of diseases cause a significant decline in the quality of life of the people who suffer from them and in their next of kin. Understanding the physical and psychosocial effects of neurodegenerative diseases contributes to clinical decision-making. It is for the above mentioned that the present study aims to examine the current evidence regarding the direct impact that phonoaaudiological disorders of motor origin generate on the quality of life in people with PD. A systematic review of the literature was carried out. The articles were searched in the following databases: PUBMED, SCIELO and WOS, during the months of June and July of the year 2020, constituting a sample of 12 works, with a maximum age of 10 years. The analysed publications mainly describe the aspects of quality of life that are affected in people with PD, who suffer dysphagia or dysarthria, all this through the application of different questionnaires which evaluate different aspects of this concept. The results of the review show the importance of considering within the intervention process the component of quality of life in people with E.P, since the scores obtained according to the instruments applied indicate a decrease of this component and even more with the progress of the disease, which translates into worse quality of life related to food and speech.

Abstract Sheep production systems face numerous challenges, which make decision-making a process fraught with risks and uncertainties. Modelling is a helpful tool in this respect, as it allows decision-makers to evaluate the behaviour of variables and their interrelationships, in addition to using previous or related information to predict results and simulate different scenarios. The advent of prediction models has made it possible to monitor the weight of an animal and determine the best time for its sale. Additionally, it allows producers to estimate the weights of the carcass and major marketable cuts before slaughter. All this information is directly associated with the profitability and success of the production activity. Therefore, in view of the different applications of mathematical models in production systems, this literature review examines concepts in modelling studies and the importance of using prediction models in meat sheep production. Furthermore, it addresses the practical application of modelling studies in predicting dry matter intake and carcass traits of meat sheep through correlated variables.

Resumen Los sistemas de producción ovina se enfrentan a numerosos desafíos, que hacen de la toma de decisiones un proceso lleno de riesgos e incertidumbres. En este sentido, la modelación es una herramienta útil, ya que permite a los tomadores de decisiones evaluar el comportamiento de las variables y sus interrelaciones, además de utilizar información previa o relacionada para predecir resultados y simular diferentes escenarios. El advenimiento de los modelos de predicción ha permitido monitorear el peso de un animal y determinar el mejor momento para su venta. Además, permite a los productores estimar los pesos de la canal y los principales cortes comercializables antes del sacrificio. Toda esta información está directamente asociada a la rentabilidad y el éxito de la actividad productiva. Por lo tanto, en vista de las diferentes aplicaciones de los modelos matemáticos en los sistemas de producción, esta revisión de la literatura examina los conceptos en los estudios de modelación y la importancia de utilizar modelos de predicción en la producción de ovinos de carne. Además, aborda la aplicación práctica de los estudios de modelación en la predicción de la ingesta de materia seca y los rasgos de la canal de ovinos de carne a través de variables correlacionadas.

ABSTRACT Objective: The aim of the present study was to evaluate the prevalence of total cholesterol (TC) and low-density lipoprotein (LDL) alterations in children and adolescents in Brazil. Materials and methods: A systematic review and meta-analysis of prevalence. The search for articles was carried out in the databases: Medline (PubMed), Embase, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (Lilacs). The meta-analysis was performed using the random effects model. The I² test was used to identify heterogeneity. Results: The present metanalysis revealed a significant prevalence of altered lipid profile in children and adolescents in Brazil. Regarding lipoprotein fractions, the prevalence of altered TC level was 27.47% (95% CI 24.36-30.82), and a smaller prevalence was observed for LDL cholesterol (19.29% – 95% CI 15.21-24.16). The models revealed high heterogeneity (I² = 99%; p < 0.01), however the precise source of it was not identified; although type of school, age group, year and the region of Brazil appeared to influence the estimations of altered lipid profiles. Conclusion: An important prevalence of lipid alterations was observed among Brazilian children and adolescents. Those results reinforce the importance of knowing the lipid profile of children and adolescents to perform early interventions for this public.

Abstract This study evaluated the bioactive potential of a macro-porous chitosan scaffold incorporated with calcium hydroxide (CH-Ca) and functionalized with bioactive doses of simvastatin (SV) for bone tissue regeneration. Initially, the bioactive dose of SV in osteoblastic cells (SAOS-2) was determined. For the direct contact experiment, SAOS-2 cells were plated on scaffolds to assess cell viability and osteogenic differentiation. The second assay was performed at a distance using extracts from scaffolds incubated in culture medium to assess the effect of conditioned medium on viability and osteogenic differentiation. The initial screening showed that 1 μM SV presented the best biostimulating effects, and this dose was selected for incorporation into the CH-Ca and pure chitosan (CH) scaffolds. The cells remained viable throughout the direct contact experiment, with the greatest cell density in the CH-Ca and CH-Ca-SV scaffolds because of their higher porosity. The CH-Ca-SV scaffold showed the most intense bio-stimulating effect in assays in the presence and absence of osteogenic medium, leading to an increased deposition of mineralized matrix. There was an increase in the viability of cells exposed to the extracts for CH-Ca, CH-SV, and CH-Ca-SV during the one-day period. There was an increase in ALP activity in the CH-Ca and CH-Ca-SV; however, the CH-Ca-SV scaffold resulted in an intense increase in the deposition of mineralized nodules, approximately 56.4% at 7 days and 117% at 14 days, compared with CH (control). In conclusion, functionalization of the CH-Ca scaffold with SV promoted an increase in bioactivity, presenting a promising option for bone tissue regeneration.

ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike’s Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

Abstract The consequences of traumatic dental injuries can be even more serious when their emergency management procedures are inadequate. Since traumatic accidents frequently occur at school, it is crucial that teachers be knowledgeable enough to assist an injured child. This study aimed to assess the knowledge and attitudes of the elementary school teachers of a Brazilian city toward dental trauma in permanent teeth, and its emergency practices. A combination of convenience and snowball sampling methods was used. An online questionnaire was distributed through social media, consisting of three parts: demographic characteristics and professional information; previous experiences and attitudes toward dental trauma; teachers’ knowledge of this subject. Descriptive and statistical analyses were carried out. Pearson chi-squared test (p < 0.05) was used. A total of 217 teachers participated in the study. The power of the sample was 95%. Half of the teachers had already witnessed a dental trauma incident involving students, and 70.5% never received any information on the subject. The teachers who were provided previous information were the ones who opted to search for the tooth fragment (p=0.036) in cases of crown fracture, and for the lost tooth (p = 0.025) in cases of avulsion. They were also the ones who chose to wash the tooth in running water (p = 0.018), and look for a dentist in the first 30 or 60 minutes after the trauma (p = 0.026). Most of the teachers assessed did not have adequate knowledge of dental trauma. Having previous information was associated with more assertive practices in trauma management.

ABSTRACT: Methods in cognitive neuroscience can assist educational planning of teachers in the context of Special Education, as they favor personalized practices that value individual students with Autism Spectrum Disorder (ASD) and/or Intellectual Deficiency (ID). Therefore, this study aimed to verify the feasibility of using functional near-infrared spectroscopy (fNIRS) in clinical naturalistic situation with children and young people with ASD and/or ID during teaching tasks. In addition, the study sought to identify training strategies so that children and young people use the equipment during the activity. Seven students diagnosed with ASD and/or ID were trained with mathematics, reading and emotional expressiveness, according to their respective previous educational curricula. Each participant was exposed to two tasks in each activity, one in which he/she already had a domain and one that needed support to issue an independent response. The results indicated the feasibility of using fNIRS in this natural context of the child and the young student and provided implicit measures beyond the observational arrangement measures and task error. This is an important demonstration of the feasibility of using fNIRS in experiments in the context of Special Education.

RESUMO: Métodos em neurociência cognitiva podem auxiliar o planejamento educacional de docentes no contexto da Educação Especial, por favorecerem práticas personalizadas que valorizem a velocidade individual de aprendizagem de estudantes com transtorno do espectro do autismo (TEA) e/ou deficiência intelectual (DI). Assim sendo, este estudo objetivou verificar a viabilidade de uso da Espectroscopia Funcional de Infravermelho Próximo (fNIRS) em situação naturalística clínica com crianças e jovens com TEA e/ou DI durante tarefas de ensino. Ademais, o estudo buscou identificar as estratégias de treino para que as crianças e os jovens utilizassem o equipamento durante a realização da atividade. Sete estudantes com diagnóstico de TEA e/ou DI foram treinados com atividades de matemática, leitura e expressividade emocional, de acordo com seus respectivos currículos educacionais prévios. Cada participante foi exposto a duas tarefas em cada atividade, uma na qual já apresentava domínio e outra que necessitava de apoio para emitir uma resposta independente. Os resultados indicaram a viabilidade de uso do fNIRS nesse contexto natural da criança e do jovem e forneceram medidas implícitas para além das medidas observacionais de acerto e erro na tarefa. Esta é uma importante demonstração da viabilidade do uso do fNIRS em experimentos no contexto da Educação Especial.

ABSTRACT Objective: To verify the association between sociodemographic, clinical, environmental, cognitive, and emotional factors and the decision time of people with ischemic stroke to seek a health service after the onset of symptoms or wake up stroke. Method: Cross-sectional study carried out from March to October 2019, with 304 patients, in a public hospital, a reference in neurology. Data obtained through interview and from medical records. Decision time was analyzed as a geometric mean. In the bivariate and multivariate analyses, linear regression was used and the Akaike Information Criterion was used to select the best model. Statistical significance of 5% was adopted. Results: The geometric mean of decision time was 0.30h (95% CI 0.23–0.39). The final model explained this time in 41%, showing an increase of 0.5 min for people with arterial hypertension; 10.8 min for those who waited for symptoms to improve; 1.4 min for those who were alone at the onset of symptoms; 3.9 min for those at home; 3.2 min for the ones at work; and 2.1 for those on the street/public space. Conclusion: The mean decision time for seeking a health service was high and influenced by clinical, environmental, cognitive, and emotional variables. The results guide nurses regarding health education.

El modelo final explicó este tiempo en un 41%, mostrando un aumento de 0,5 min para las personas con hipertensión arterial, 10,8 min para las que esperaron a que los síntomas mejoraran, 1,4 min para las que estaban solas al inicio de los síntomas, 3, 9 min para las que estaban en casa, 3,2 min para los que estaban en el trabajo y 2,1 en la calle/vía pública Conclusión: El tiempo promedio de decisión para buscar un servicio de salud fue alto e influenciado por variables clínicas, ambientales, cognitivas y emocionales. Los resultados orientan a los enfermeros hacia la educación en salud.

RESUMO Objetivo: Verificar a associação entre fatores sociodemográficos, clínicos, ambientais, cognitivos e emocionais e o tempo de decisão de pessoas com acidente vascular cerebral isquêmico para procurar um serviço de saúde após o início dos sintomas ou Wake up stroke Método: Estudo transversal realizado de março a outubro de 2019, com 304 pacientes, em hospital público, referência em neurologia. Dados obtidos por entrevista e no prontuário. O tempo de decisão foi analisado em média geométrica. Nas análises bivariadas e multivariada foi usada a regressão linear e o Critério de Informação de Akaike foi usado na seleção do melhor modelo. Adotou- se significância estatística de 5% Resultados: A média geométrica do tempo de decisão foi de 0,30h (IC 95% 0,23-0,39). O modelo final explicou em 41% esse tempo, mostrando aumento de 0,5 min para pessoas com hipertensão arterial; 10,8 min para quem esperou os sintomas melhorarem; 1,4 min para quem estava sozinho no início dos sintomas; 3,9 min para quem estava em casa; 3,2 min no trabalho e 2,1 na rua/via pública Conclusão: A média do tempo de decisão para procura de serviço de saúde foi alta e influenciada por variáveis clínicas, ambientais, cognitivas e emocionais. Os resultados orientam enfermeiros para a educação em saúde.
