The plasmonic properties of Au nanoparticles (AuNP), which allow the observation of enhanced spectroscopic effects, are strongly affected by the aggregation and precipitation caused by the strong interactions between nanoparticles. To avoid AuNP aggregation and precipitation, the present study proposes coating with MnO2, forming AuNP@MnO2 core-shell structures. The MnO2 layers presented 1-10 nm thickness so that highly surface-enhanced fluorescence was obtained with maximum intensity given by 5 nm thick MnO2. The decrease in Raman intensity could be controlled, despite the inherent reduction in surface-enhanced Raman scattering (SERS) intensity with increasing adsorbate-surface distance. The decrease in Raman intensity was compensated by increasing AuNP stability caused by the MnO2 shell.

Resumo Fundamento A ecocardiografia tridimensional (ECO 3D) permite a geração de uma curva volume-tempo representativa das alterações no volume ventricular esquerdo (VE) ao longo de todo o ciclo cardíaco. Objetivo O presente estudo tem como objetivo demonstrar as adaptações hemodinâmicas presentes na cardiomiopatia chagásica (CC) por meio das medidas de volume e fluxo obtidas pela curva volume-tempo por ECO 3D. Métodos Vinte pacientes com CC e 15 indivíduos saudáveis foram incluídos prospectivamente em um estudo de desenho transversal. Realizou-se ECO 3D em todos os indivíduos e as curvas volume-tempo do VE foram geradas. O fluxo foi obtido pela primeira derivada da curva volume-tempo por meio do software MATLAB. A significância estatística foi definida com p<0,05. Resultados Embora os pacientes com CC tivessem menor fração de ejeção do VE em comparação com o grupo controle (29,8±7,5 vs. 57,7±6,1, p<0,001), o volume (61,5±25,2 vs. 53,8±21,0, p=0,364) e o fluxo de ejeção máximo durante a sístole (-360,3±147,5 vs. -305,6±126,0, p = 0,231) mostraram-se semelhantes entre os grupos. Da mesma forma, o fluxo máximo na fase de enchimento inicial e durante a contração atrial mostrou-se semelhante entre os grupos. Um aumento na pré-carga expressa pelo volume diastólico final do VE (204,8±79,4 vs. 93,0±32,6), p<0,001) pode manter o fluxo e o volume ejetado semelhantes aos dos controles. Conclusão Com uma ferramenta não invasiva, demonstramos que o aumento no volume diastólico final do VE pode ser o principal mecanismo de adaptação que mantém o fluxo e o volume ejetado no cenário de disfunção sistólica ventricular esquerda severa.

Abstract Background Three-dimensional echocardiography (3D ECHO) allows the generation of a volume-time curve representative of changes in the left ventricular (LV) volume throughout the entire cardiac cycle. Objective This study aims to demonstrate the hemodynamic adaptations present in Chagas cardiomyopathy (CC) by means of the volume and flow measurements obtained by the volume-time curve by 3D ECHO. Methods Twenty patients with CC and 15 healthy subjects were prospectively enrolled in a cross-sectional design study. 3D ECHO was performed in all subjects and the volume over time curves of the LV was generated. The flow was obtained by the first derivative of the volume-time curve using the software MATLAB. Statistical significance was set at p<0.05. Results Although CC patients had lower LV ejection fraction compared to the control group (29.8±7.5 vs. 57.7±6.1, p<0.001), stroke volume (61.5±25.2 vs. 53.8±21.0, p=0.364) and maximum ejection flow during systole (-360.3±147.5 vs. -305.6±126.0, p=0.231) were similar between the groups. Likewise, the maximum flow in the early diastolic filling phase and during atrial contraction was similar between groups. An increase in preload expressed by LV end diastolic volume (204.8±79.4 vs. 93.0±32.6), p<0.001) may maintain the flow and stroke volumes similar to the controls. Conclusion Using a non-invasive tool, we demonstrated that an increase in LV end-diastolic volume may be the main adaptation mechanism that maintains the flow and stroke volumes in the setting of severe LV systolic dysfunction.

Metal-organic frameworks (MOFs) based on Calcium-terephthalate(Ca-MOFs) were synthesized by the sonochemical method and applied to remove methylene blue (MB) from an aqueous solution via adsorption. The samples were prepared and characterized by X-ray Powder Diffraction (PXRD), Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), Thermal Analysis (TGA-DTA), and Scanning Electron Microscopy (SEM). The studied of the effect of the synthesis temperature on the crystallization of MOFs indicated two different crystal structures were identified, Ca(BDC) and Ca(BDC)(H2O)3. Observed that samples with a higher proportion of the Ca(BDC) phase showed greater dye adsorption capacity. The experimental data fit the pseudo-second-order kinetic model. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms, and the isotherm constants were also determined. The adsorption equilibrium data preferably fit the Freundlich model. The samples were applied to methylene blue adsorption at pH 5.6, with maximum adsorption of 60.241 μmol.g-1 and high reuse efficiency, reaching 97% of the initial adsorption capacity in the second reuse cycle.

Abstract Background: we aimed to investigate the isolated effect of tele-exercises (TE) and their combined effect with nutritional coaching (NC) on health-related parameters of overweight and obese individuals. Methods: forty-one overweight (body mass index ≥ 25 kg/m2) and obese (body mass index ≥ 30 kg/m2) women were randomly assigned to the experimental groups: TE (n = 20) or TE+NC (n = 21). TE was applied 3 days/week in both groups, while TE+NC also received NC 1 day/week. Anthropometric, body composition, and exercise capacity-related outcomes, quality of life, and eating behavior were assessed before and after 8 weeks of the intervention. Results: a significant main time effect (p < 0.01) was detected for flexibility, isometric muscle strength and dynamic muscle endurance, but no main group effect was noted (p > 0.05). On the other hand, neither a significant main time nor group effect (p > 0.05) was detected in the anthropometric and body composition measures, quality of life, or eating behavior. Similarly, no significant between-group difference was observed in the absolute or relative change analysis (all comparisons, p > 0.05). Conclusions: an 8-week TE program enhanced exercise capacity, but did not impact anthropometric or body composition-related outcomes. The combination of NC+TE did not have a clinical advantage in the management of overweight and obesity.

Resumen Introducción: nuestro objetivo fue investigar el efecto aislado de los tele-ejercicios (TE) y su efecto combinado con el coaching Nutricional (CN) sobre los parámetros relacionados con la salud de las personas con sobrepeso y obesidad. Métodos: cuarenta y una mujeres con sobrepeso (índice de masa corporal ≥ 25 kg/m2) y obesas (índice de masa corporal ≥ 30 kg/m2) fueron asignadas aleatoriamente a los grupos experimentales: TE (n = 20) o TE+CN (n = 21). La TE se aplicó 3 días/semana en ambos grupos, mientras que el grupo TE+CN también recibió NC 1 día/semana. Se evaluaron los resultados antropométricos, la composición corporal y la capacidad de ejercicio, la calidad de vida y la conducta alimentaria antes y después de 8 semanas de intervención. Resultados: se detectó un efecto de tiempo principal significativo (p < 0,01) para la flexibilidad, la fuerza muscular isométrica y la resistencia muscular dinámica, pero no se observó ningún efecto de grupo principal (p > 0,05). Por otro lado, no se detectó ningún efecto de tiempo principal ni de grupo significativo (p > 0,05) en las medidas antropométricas y de composición corporal, calidad de vida o conducta alimentaria. De manera similar, no se observaron diferencias significativas entre los grupos en el análisis del cambio absoluto o relativo (todas las comparaciones, p > 0,05). Conclusiones: un programa de TE de 8 semanas mejoró la capacidad de ejercicio pero no afectó los resultados antropométricos o relacionados con la composición corporal. La combinación de CN + TE no obtuvo ninguna ventaja clínica en el manejo del sobrepeso y la obesidad.

Abstract Introduction: To analyze the food quality of elderly participants in a multi-professional project for health promotion and healthy longevity. Methodology: 55 older adults aged ≥60 years (66.03±3.68 years) residents in the south of Brazil were recruited. However, 28 elderlies dropped out of the interventions. Thus, 27 elderlies were assessed (before and after 12-week interventions). To evaluate food quality, the data from the food record of three non-consecutive days and the healthy eating index (HEI) were used, which were applied before and after interventions. The intervention was developed for three months, with theoretical-practical classes on multidisciplinary groups as physical education, psychology, and nutrition (with food reeducation - without nutrition plan). The mean, (±) standard deviation, and 95% confidence interval (95%CI) were calculated. The comparison between pre- and post-intervention was performed by paired T-test, assuming a p≤0.05. Results: After 12 weeks, it was observed that the elderly showed higher values for the HEI after the interventions (pre: 47.78±14.23 points; 95%CI: 42.41-53.15, versus 56.30±13.05, 95%CI: 51.37-61.22; with p=0.029; d=0.59; medium effect). Conclusions: A multidisciplinary approach including a nutritional intervention could promote positive changes in the food quality of the elderly investigated. As a limitation, the absence of a control group and the conduction of a randomized controlled trial are highlighted. However, this study already promotes directions to provide nutritional health in older people.

Resumen Introducción: Analizar la calidad alimentaria de los adultos mayores participantes en un proyecto multiprofesional de promoción de la salud y longevidad saludable. Metodología: Se reclutaron 55 adultos mayores de ≥60 años (66,03±3,68 años) residentes en el sur de Brasil. Sin embargo, 28 ancianos abandonaron las intervenciones. Así, se evaluaron 27 ancianos (antes y después de las intervenciones de 12 semanas). Para evaluar la calidad de los alimentos se utilizaron los datos del registro alimentario de tres días no consecutivos y el índice de alimentación saludable (IES), que se aplicaron antes y después de las intervenciones. La intervención se desarrolló durante tres meses, con clases teórico-prácticas en grupos multidisciplinares como educación física, psicología y nutrición (con reeducación alimentaria - sin plan de nutrición). Se calcularon la media, la desviación estándar (±) y el intervalo de confianza del 95% (IC del 95%). La comparación entre pre y postintervención se realizó mediante la prueba T pareada, asumiendo una p≤0,05. Resultados: Después de 12 semanas, se observó que los ancianos mostraron valores más altos para la IES después de las intervenciones (pre: 47,78±14,23 puntos; IC95%: 42,41-53,15, versus 56,30±13,05, IC95%: 51,37-61,22; con p=0,029; d=0,59; efecto medio). Conclusiones: Un enfoque multidisciplinario que incluya una intervención nutricional podría promover cambios positivos en la calidad alimentaria de los ancianos investigados. Como limitación se destaca la ausencia de un grupo control y la realización de un ensayo controlado aleatorizado. Sin embargo, este estudio ya promueve direcciones para brindar salud nutricional a las personas mayores.

SUMMARY: Previous evidence indicates that body fat can distinguish Brazilian jiu-jitsu (BJJ) athletes according to the competitive level. However, propositions of cut-off points for establishing classifications of body fat percentage for combat sports athletes and, specifically, for BJJ athletes are still incipient in the literature. In this sense, the main aim of the present study was to establish a normative table for the classification of body fat percentage in BJJ athletes. As a secondary aim, athletes were compared according to competitive level. Ninety male BJJ athletes (aged: 29.0 ± 8.2 years; practice time: 6.0 ± 2.1 years; body mass: 82.1 ± 12.7 kg; height: 175.9 ± 6.5 cm; fat mass: 16.0 ± 8.9 kg; bone mineral content: 3.7 ± 0.6 kg; muscle mass: 37.9 ± 5.4 kg; body fat percentage: 17.3 ± 6.8 %; basal metabolic rate: 1811.4 ± 193.4 kcal) from different competitive levels: state (n= 42), national (n= 26) and international (n= 22) took part in this study. All athletes had their body composition measured via tetrapolar bioelectrical impedance. Percentiles p10, p25, p50, p75, and p90 were used to establish the classification. As a result, the following classification was obtained: <7.7 % (very low); ≥7.7-11.5 % (low); 11.6-17.0 % (medium); 17.1-24.0 % (high) and ≥24.1 % (very high). State-level athletes had a higher fat percentage than national and international-level athletes (p<0.05). The proposed cut-off points can help professionals responsible for sports training and nutritional prescription in monitoring the body fat of BJJ athletes.

RESUMEN: La grasa corporal puede distinguir a los atletas de jiu-jitsu brasileño (BJJ) según el nivel competitivo. Sin embargo, las propuestas de puntos de corte para establecer clasificaciones de porcentaje de grasa corporal para deportistas de deportes de combate y, específicamente, para deportistas de BJJ son aún incipientes en la literatura. En este sentido, el objetivo principal del presente estudio fue establecer una tabla normativa para la clasificación del porcentaje de grasa corporal en atletas de BJJ. Secundariamente, comparar a los deportistas según el nivel competitivo. Participaron noventa atletas masculinos de BJJ (edad: 29,0 ± 8,2 años; tiempo de práctica: 6,0 ± 2,1 años; masa corporal: 82,1 ± 12,7 kg; estatura: 175,9 ± 6,5 cm; masa adiposa: 16,0 ± 8,9 kg; contenido mineral óseo: 3,7 ± 0,6 kg; masa muscular: 37,9 ± 5,4 kg; porcentaje de grasa corporal: 17,3 ± 6,8 %; tasa metabólica basal: 1811,4 ± 193,4 kcal) de diferentes niveles competitivos: estatal (n= 42), nacional (n= 26) e internacional (n= 22). Se evaluó la composición corporal a través de bioimpedancia tetrapolar. Para establecer la clasificación se utilizaron los percentiles p10, p25, p50, p75 y p90. Como resultado se obtuvo la siguiente clasificación: <7,7 % (muy bajo); ≥7,7-11,5 % (bajo); 11,6-17,0 % (medio); 17,1-24,0 % (alto) y ≥24,1 % (muy alto). Los atletas de nivel estatal tenían un porcentaje de grasa corporal más alto respecto a los atletas de nivel nacional e internacional (p <0.05). Los puntos de corte propuestos pueden ser útiles para monitorizar la grasa corporal de los atletas de BJJ.

ABSTRACT Introduction: Overweight negatively impacts the cardiovascular system and osteomyoarticular, promoting pain in the joints of the lower limbs. Therefore, strategies have been applied to reduce overweight through lifestyle changes. Objective: To investigate the effects of two multidisciplinary intervention programs on the health-related physical fitness of obese women with pain symptoms in the knees. Methods: Women between 40 and 59 years of age with obesity (n=59) were evaluated pre- and post-intervention in terms of anthropometry, body composition, physical fitness, level of disability in the knee and hip, and health-related quality of life. A randomized experimental study of parallel groups was conducted for 8 weeks, using two resistance exercise programs and food reeducation. All participants received the same nutritional interventions. For physical exercises, the participants were randomized into two groups: G1, the “strength group” using machines (n=30), and G2, the “body weight” group (n=29). Twenty-eight women (G1, n=18; G2, n=10) were included in the final analyses. This study was approved by Ethics Local Committee. The groups and time were evaluated using two-way analysis of variance with repeated measures. A p<0.05 was assumed for all analyses. Results: A time effect was identified, with higher values for maximum isometric lumbar traction strength after the intervention period in both groups (p<0.05). However, no significant differences were identified among the other variables investigated (p>0.05). Conclusion: The absence of significant results for all variables, except maximum isometric lumbar traction, may be justified by the moderate adherence of the participants to interventions (approximately 59%-66%) since the study was conducted during the period of social isolation (COVID-19). However, it is believed that the intervention models were positive in maintaining the variables studied.

RESUMEN Introducción: El sobrepeso afecta negativamente al sistema cardiovascular y al osteomioarticular, favoreciendo el dolor en las articulaciones de las extremidades inferiores. Por lo tanto, se han aplicado estrategias para reducir el sobrepeso a través de cambios en el estilo de vida. Objetivo: investigar los efectos de dos programas de intervención multidisciplinares sobre la aptitud física relacionada con la salud de mujeres obesas con síntomas de dolor en las rodillas. Métodos: Se evaluó a mujeres entre 40 y 59 años con obesidad (n=59) en el tiempo pre y post intervención en antropometría, composición corporal, aptitud física, nivel de discapacidad en rodilla y cadera y calidad de vida relacionada con la salud. Se realizó un ensayo clínico aleatorizado de grupos paralelos, utilizando dos programas de ejercicio de resistencia y reeducación alimentaria, durante ocho semanas. Todos los participantes recibieron el mismo contenido de intervención nutricional y para ejercicios físicos se aleatorizaron en dos grupos, G1 siendo el "grupo de fuerza" utilizando máquinas (n=30), y G2 siendo el grupo de "entrenamiento funcional" (n=29). Veintiocho mujeres (G1=18 + G2=10) fueron incluidas en los análisis finales. Este estudio fue aprobado por el Comité Local de Ética. Los grupos y el tiempo se evaluaron mediante análisis bidireccional de la varianza, con medidas repetidas. Se asumió una p < 0,05 para todos los análisis. Resultados: se identificó un efecto de tiempo, con valores más altos para la fuerza máxima de tracción lumbar isométrica (MILTS), luego del período de intervención en ambos grupos (p < 0.05). Sin embargo, para las otras variables investigadas, no se identificaron diferencias significativas (p > 0.05). Conclusión: La ausencia de resultados significativos para todas las variables, excepto FIMTL, puede estar justificada por la adherencia moderada de los participantes a las intervenciones (~ 59% a 66%) ya que el estudio se realizó durante el período de aislamiento social (COVID-19). Sin embargo, se cree que los modelos de intervención fueron positivos en el mantenimiento de las variables estudiadas.

Resumo Frente às elevadas taxas de mortalidade e encarceramento de jovens brasileiros negros, pobres e moradores de periferia, apresenta-se pesquisa transdisciplinar que buscou qualificar os eventos, transições e rupturas que marcam suas trajetórias, analisando o ciclo de vida para desvelar seus nexos, movimentos e fatores de risco. Para tanto, partimos do levantamento de Planos Individuais de Atendimento (PIA) de adolescentes em cumprimento de medida socioeducativa para, posteriormente, efetuar uma busca ativa por esses sujeitos, a fim de aplicar um questionário e convidá-los a contarem suas histórias de vida por meio da metodologia de Narrativas Memorialísticas. A partir da análise de um caso que revela o potencial universal de cada vida singular, foram analisados quatro eixos identificados a partir do próprio discurso do jovem, a saber: a violência do Estado, a adolescência, a mortalidade e a aposta. Em contraposição à precariedade e à ausência de amparo a que algumas vidas são lançadas, desvelando a morte, uma aposta decidida, traduzida pela oferta de algum enlaçamento, parece convocar a construção de saídas possíveis.

Abstract Considering the high rates of mortality and incarceration among young black Brazilians, the poor, and the periphery residents, we present this transdisciplinary research that sought to qualify the events, transitions, and ruptures that mark their trajectories, analysing their life cycle to unveil its links, movements, and risk factors. We started with the survey of Planos Individuais de Atendimento (Individual Care Plans - PIA) of adolescents in compliance with a socio-educational measure, and later with an active search for these subjects, to apply a questionnaire and invite them to tell their life stories by using the methodology of Narrative Memoir. From a case analysis, which reveals the universal potential of each singular life, we analyzed four axes identified from the young man’s own discourse, namely: State violence, adolescence, mortality, and wager. In contrast to the precariousness and the lack of support in their lives, risking death, a determined wager, in the form of an unsavory cooperation, may create possible way outs.

Resumen Ante las altas tasas de mortalidad y encarcelamiento de jóvenes negros brasileños, pobres y residentes en la periferia, se presenta una investigación transdisciplinaria que busca calificar los eventos, transiciones y rupturas que marcan sus trayectorias, analizando el ciclo de vida, desvelando sus vínculos, movimientos y factores de riesgo. Para ello, se partió de la encuesta de Planos Individuais de Atendimento (“Planes de Atención Individualizados”) de adolescentes en cumplimiento de medida socioeducativa para luego realizar una búsqueda activa de estos temas con el fin de aplicarles un cuestionario e invitarlos a contar sus historias de vida utilizando la metodología de Narrativas Memorialistas. A partir del análisis de caso, que revela el potencial universal de cada vida singular, se analizaron cuatro ejes identificados a partir del propio discurso del joven: la violencia del Estado, la adolescencia, la mortalidad y la apuesta. En contraste con la precariedad y la falta de apoyo a la que se arrojan algunas vidas, desvelando la muerte, una apuesta decidida, traducida en el ofrecimiento de algún vínculo, parece llamar a la construcción de posibles salidas.

Abstract The objective of this work was to evaluate the influence of colored shade mesh and plant density on the morphological characteristics of Corymbia citriodora seedlings. The highest radiation efficiency was found in the blue mesh, 7.01 g MJ-1 and 5.72 g MJ-1 for average and high density respectively. For dry matter and leaf area index at high density, the treatment without mesh followed by the red mesh was the best. The chlorophyll index did not differ between treatments, with mean values of 206.4, 59.1 and 262.0 for chlorophyll a, b and total, respectively. Using principal component analysis, we found the total variance to be 70%. The use of colored shade mesh and plant density altered the radiation use efficiency and dry matter accumulation. Leaf area index was affected only by plant density. The red mesh resulted in the most similar values to the treatment without mesh.

RESUMO O presente texto tem por objetivo discutir possibilidades de incorporação de temas emergentes da cultura fitness digital ao léxico da educação física escola. Estas derivam de interações relacionadas a um aplicativo fitness que faz uso da inteligência artificial. Com base na Teoria Ator-Rede, identificou-se quatro temáticas: espetacularização fitness, que envolve a intensa exibição de si; a bolha fitness, fruto da ação de algoritmos; a culpabilização fitness, sob a égide do sujeito empreendedor de si; e o biohacking, que transita pela autoexperimentação para uma auto otimização. Conclui-se que a cultura fitness digital possui elementos pouco explorados, embora relevantes à escola.

ABSTRACT This paper aims to discuss possibilities to add emerging themes of digital fitness culture in physical education at school. These themes were collected from interactions related to a fitness app based on artificial intelligence. Through the Actor-Network Theory, four themes were identified: fitness spectacularization, a process of strong self-exhibition; the fitness bubble, the result of the action of algorithms; fitness blame, which produces the self-entrepreneur; and biohacking, which ranges from self-experimentation to self-optimization. It is concluded that the digital fitness culture has little explored elements, although relevant to the school.

RESUMEN Este texto tiene como objetivo discutir las posibilidades de incorporar temas de la cultura del fitness digital en la educación física escolar. Estos temas derivan de interacciones relacionadas con una aplicación de fitness basada en inteligencia artificial. Basado en la Teoría del Actor-Red, se identificaron cuatro temas: la espectacularización fitness, que implica la exhibición intensa de uno mismo; la burbuja fitness, fruto de la acción de los algoritmos; culpabilización fitness, que produz o auto-empreendedor; y biohacking, que pasa de la autoexperimentación a la autooptimización. Se concluye que la cultura del fitness digital tiene elementos poco explorados, aunque relevantes para la escuela.

Resumo A troca de missivas entre os intelectuais, no decorrer do século XX, se tornou um meio eficaz para a circulação de textos inéditos entre intelectuais modernistas. É importante destacar que, se este não foi um hábito restrito a esse momento histórico, desenvolveu-se de forma considerável nele. As correspondências trocadas entre os integrantes do Modernismo brasileiro e da vanguarda argentina revelam que a partilha do texto inédito se estabeleceu entre eles como uma prática constante. Luís da Câmara Cascudo, Monteiro Lobato, Mário de Andrade, Joaquim Inojosa, Braulio Sanchéz-Saes e Luís E. Sotto, foram, sem dúvida, alguns desses intelectuais. O artigo tem por objetivo estudar a ação de Luís da Câmara Cascudo na divulgação do modernismo brasileiro na Argentina Intelectual durante os anos de 1922 a 1925.

Abstract The exchange of letters between intellectuals during the 20th century became an effective means to circulate unpublished texts among modernist intellectuals. It is essential to highlight that if this was not a habit restricted to that historical moment, it developed considerably. Correspondence between the Brazilian Modernism members and the Argentine avant-garde reveals that the sharing of unpublished text was established between them as a constant practice. Luís da Câmara Cascudo, Monteiro Lobato, Mário de Andrade, Joaquim Inojosa, Braulio Sanchéz-Saes, and Luís E. Sotto were undoubtedly a few of these intellectuals. This article aims to study the action of Luís da Câmara Cascudo disseminating Brazilian modernism through Intellectual Argentina from 1922 to 1925.

Resumo Este artigo descreve os modos pelos quais usuários de um aplicativo fitness que prescreve exercícios físicos personalizados orientam suas condutas em interação com números gerados por self-tracking. Baseado na Teoria Ator-Rede, foram analisadas as interações derivadas de relações entre usuário, aplicativo e rede a qual ele está integrado. Tendo a autoexperimentação como demarcador, os resultados apontaram duas perspectivas de conduta orientada por dados: aqueles que seguem os insights apontados pela tecnologia, ainda que com ajustes, e aqueles que realizam experimentos mais aprofundados, caracterizados como biohackers. Muitos dos biohackers se tornam também influenciadores digitais e constituem uma espécie de rede de colaboração nas mídias sociais. Conclui-se que os usuários, enquanto sujeitos empreendedores de si, orientam suas condutas através dos números, produzem relatórios que envolvem dados de diversas atividades humanas, por meio de diferentes softwares e realizam autoexperimentação.

Abstract This article describes the ways in which users of a fitness app that prescribes personalized exercise guide their behavior through the numbers generated by self-tracking. Based on the Actor-Network Theory, interactions between user, fitness app and the network to which it is integrated were analyzed. The results suggest self-experimentation as a common behavior and two perspectives of data-driven behavior: those that follow the insights recommended by the technology, albeit with adaptations; and those who perform more consistent experiments, characterized as biohackers. Many of the biohackers also become digital influencers, and form a kind of collaboration network on social media. It is concluded that users, as entrepreneurs of themselves, guide their behavior through numbers, produce reports that involve data from various human activities, through different software and practice self-experimentation.

Resumen Este artículo describe las formas en que los usuarios de una aplicación de fitness que prescribe ejercicio personalizado orientan sus conductas interactuando con los números generados por self-traking. A partir de la Teoría Actor-Red, se analizaron las interacciones derivadas de las relaciones entre usuario, aplicación de fitness y la red en la que está integrado. Con la autoexperimentación como marcador, los resultados muestran dos perspectivas de conducta orientada por datos: los que siguen aquello que indica la tecnología, aunque con ajustes, y aquellos que realizan experimentos más profundos, caracterizados como biohackers. Muchos de los biohackers también se convierten en influencers digitales y forman una especie de red colaborativa en las redes sociales. Se concluye que los usuarios, como emprendedores de sí mismos, orientan sus conductas a través de los números, producen informes que incluyen datos de diversas actividades humanas, a través de diferentes softwares, y practican la autoexperimentación.

Resumo Fundamento: A hipertrofia ventricular esquerda (HVE) é um importante fator de risco cardiovascular, independente da hipertensão arterial. Apesar da evolução dos exames de imagem, o eletrocardiograma (ECG) ainda é o mais utilizado na avaliação inicial, porém, com baixa sensibilidade. Objetivo: Avaliar o desempenho dos principais critérios eletrocardiográficos para HVE em indivíduos hipertensos idosos e muito idosos. Métodos: Em coorte de hipertensos foram realizados ECGs e EcoDopplercardiogramas (ECO), e separados em três grupos etários: <60 anos, Grupo I; 60-79 anos Grupo II; e ≥80 anos, Grupo III. Os critérios eletrocardiográficos mais utilizados foram aplicados para o diagnóstico da HVE: Perúgia; Peguero-Lo Presti; Gubner-Ungerleider; Narita; (Rm+Sm) x duração; Cornell voltagem; Cornell voltagem duração; Sokolow-Lyon voltagem; R de aVL ≥11 mm; RaVL duração. Na avaliação do desempenho desses critérios, além da sensibilidade (Sen) e especificidade (Esp), foram analisadas as “Odds Ratios diagnóstico” (DOR). Consideramos p-valor <0,05 para as análises, com testes bi-caudais. Resultados: Em 2.458 pacientes, a HVE estava presente pelo ECO em 781 (31,7%). Nos Grupos I e II, os melhores desempenhos foram para os critérios de Narita, Perúgia, (Rm+Sm) x duração, sem diferenças estatísticas entre eles. No Grupo III (muito idosos) os critérios de Perúgia e (Rm+Sm) x duração tiveram os melhores desempenhos: Perúgia [44,7/89,3; (Sen/Esp)] e (Rm+Sm) duração [39,4%/91,3%; (Sen/Esp), p<0,05)], com os melhores resultados de DOR:6,8. Isto sugere que nessa população de muito idosos esses critérios têm maior poder discriminatório para separar pacientes com HVE. Conclusão: Nos hipertensos muito idosos os critérios eletrocardiográficos de Perúgia e (Rm+Sm) x duração apresentaram os melhores desempenhos diagnósticos para HVE.

Abstract Background: Left ventricular hypertrophy (LVH) is an important cardiovascular risk factor, regardless of arterial hypertension. Despite the evolution of imaging tests, the electrocardiogram (ECG) is still the most used in the initial evaluation, however, with low sensitivity. Objective: To evaluate the performance of the main electrocardiographic criteria for LVH in elderly and very elderly hypertensive individuals. Methods: In a cohort of hypertensive patients, ECGs and doppler echocardiographies (ECHO) were performed and separated into three age groups: <60 years, Group I; 60-79 years Group II; and ≥80 years, Group III. The most used electrocardiographic criteria were applied for the diagnosis of LVH: Perugia; Pegaro-Lo Presti; Gubner-Ungerleider; Narita; (Rm+Sm) x duration; Cornell voltage; Cornell voltage duration; Sokolow-Lyon voltage; R of aVL ≥11 mm; RaVL duration. In evaluating the performance of these criteria, in addition to sensitivity (Sen) and specificity (Esp), the “Diagnostic Odds Ratios” (DOR) were analyzed. We considered p-value <0.05 for the analyses, with two-tailed tests. Results: In 2,458 patients, LVH was present by ECHO in 781 (31.7%). In Groups I and II, the best performances were for the criteria of Narita, Perugia, (Rm+Sm) x duration, with no statistical differences between them. In Group III (very elderly) the Perugia criteria and (Rm+Sm) x duration had the best performances: Perugia [44,7/89.3; (Sen/Esp)] and (Rm+Sm) duration [39.4%/91.3%; (Sen/Esp), p<0.05)], with the best PAIN results:6.8. This suggests that in this very elderly population, these criteria have greater discriminatory power to separate patients with LVH. Conclusion: In very elderly hypertensive patients, the Perugia electrocardiographic criteria and (Rm+Sm) x duration showed the best diagnostic performance for LVH.

Abstract Objective: the objective of the present study was to analyze the relationship between vigorous physical activity and body composition in older people who attend primary care centers. Material and methods: this study is characterized by being a descriptive, cross-sectional epidemiological study in 654 older adults (288 men and 366 women), most of them between 60 and 69 years of age (59 %), attending primary care centers in the city of Maringá, Brazil. The participants were evaluated using the International Physical Activity Questionnaire (IPAQ), anthropometric measurements, and a sociodemographic questionnaire to characterize the sample. Results: older adults who practice physical activities in primary care centers with vigorous intensity are associated with lower abdominal circumference, waist, hip, quadriceps, and calf measurements when compared to older people with low or moderate levels of physical activity. Conclusions: the practice of vigorous physical activity is related to low body perimeters (abdominal, hip, waist, calf) in older adults who attend primary care centers.

Resumen Objetivo: el objetivo del presente estudio fue analizar las relaciones entre la actividad física vigorosa y la composición corporal en personas mayores que asistían a centros de atención primaria. Material y métodos: este estudio se caracteriza por ser un estudio epidemiológico descriptivo y transversal de 654 adultos mayores (288 hombres y 366 mujeres), la mayoría de ellos de 60 a 69 años (59 %), que asistían a centros de atención primaria en la ciudad de Maringá, Brasil. Los participantes fueron evaluados con el Cuestionario Internacional de Actividad Física (IPAQ), mediciones antropométricas y un cuestionario sociodemográfico para caracterizar la muestra. Resultados: los ancianos que practican actividad física en los centros de atención primaria con intensidad vigorosa presentan mediciones más bajas de circunferencia abdominal, cintura, cadera, cuádriceps y pantorrilla en comparación con las personas mayores que practican actividad física de baja a moderada intensidad. Conclusiones: la práctica de actividad física vigorosa está relacionada con bajos perímetros corporales (abdominal, cadera, cintura, pantorrilla) en las personas adultas mayores atendidas en centros de atención primaria.
