RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12–84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19. Introdução , (DRET) COVID19.

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12–84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

ABSTRACT: Wood is an organic material and its energetic and physical properties are related to its chemical and anatomical constituents. This study evaluated the influence of the chemical constituents on the energetic and physical properties of Parapiptadeniarigida(Benth.) Brenan, Peltophorumdubium(Spreng.) Taub.,Eucalyptus grandisW. Hill × Eucalyptus urophyllaS.T. Blake (hybrid), and Schizolobiumparahyba(Vell.) Blake an agroforestry system. Five trees of each species aged 9 years were sampled. Samples were collected at a diameter at breast height (DBH) of 1.30 m above the ground and were used to analyze the chemical, energetic, and physical properties of the wood. Chemical properties influence the energetic and physical properties of wood. We reported that the higher the lignin content in the wood, the greater the correlation with the fixed carbon content (0.76) and gross calorific value (0.65). High values of fixed carbon content increased the basic density of the wood (0.80). In contrast, the lower the lignin content in the wood, the greater the correlation with the extractive content (-0.76) and volatile material content (-0.74), and the higher the volatile material content, the lower the fixed carbon content (-0.98) and gross calorific value (-0.74).

RESUMO: A madeira é um material orgânico e as suas propriedades energéticas e físicas estão relacionadas com os seus constituintes químicos e anatômicos. O presente estudo teve como objetivo avaliar a influência dos constituintes químicos nas propriedades energéticas e física da madeira de Parapiptadenia rigida (Benth.) Brenan, Peltophorum dubium (Spreng.) Taub., Eucalyptus grandis W. Hill × Eucalyptus urophylla S.T. Blake (híbrido) e Schizolobium parahyba (Vell.) Blake, provenientes de um sistema agroflorestal. Foram amostradas cinco árvores de cada espécie, com a idade de nove anos. Sendo coletadas amostras do diâmetro a altura do peito (DAP) à 1,30 m do solo, que foram utilizadas para análise das propriedades químicas, energéticas e física da madeira. As propriedades químicas influenciam nas propriedades energéticas e física da madeira. Quanto maior o teor de lignina na madeira maior será a correlação com o teor de carbono fixo (0,76) e de poder calorífico superior (0,65), assim como, elevados valores de teor de carbono fixo aumentam a massa específica básica da madeira (0,80). Em contrapartida, quanto menor o teor de lignina na madeira maior será a correlação com o teor de extrativos (-0,76) e teor de materiais voláteis (-0,74), sendo que, maiores valores de teor de materiais voláteis reduzem o teor de carbono fixo (-0,98) e o poder calorífico superior (-0,74) da madeira.

The increase in anthropogenic activity over time has led to an exponential increase in greenhouse gas emissions, especially CO2. Proftable technologies for CO2 capture and separation are conspicuous, and porous biochars derived from biomass waste can be a useful solution. Herein, we produced activated nitrogen-doped biochars for CO2 capture from corn husk waste, urea and K2CO3, named N-Bio-X (X = 600, 700, and 800 °C). N-Bio-X exhibited microporosity and different nitrogen contents and thus played an important role in the adsorption of CO2. N-Bio-700 exhibited the highest CO2 adsorption capacity, fastest adsorption kinetics and excellent stability after multiple adsorption-desorption cycles. N-Bio-600 showed excellent CO2/N2 selectivity, induced by nitrogen sites, particularly pyridinic and graphitic nitrogen. The cost-effectiveness of the raw material, coupled with its high adsorption capacity, rapid kinetics, and stable properties, provided highly promising N-doped biochars for practical implementation in CO2 capture and separations in postcombustion processes. emissions CO conspicuous solution Herein nitrogendoped doped K2CO3 KCO K NBioX N Bio X 600 700 80 °C.

ABSTRACT Purpose: To evaluate the profile of graduates of the Postgraduate Program (PGP) in Cardiology of a public federal university, according to sociodemographic factors and professional trajectory. Methods: The variables were collected from databases from the observed institution and digital platforms. The analysis of differences between the various levels of degrees was carried out in three cohorts: the entire historical series (graduates from 1978–2021), the first 20 years (1978–1997) and the second 20 years (1998–2018). Results: The results demonstrated that most students from the PGP completed a PhD and are men over 30 years old, they came from public universities and the Southeast region. In the first 20 years, significant differences were observed in the distribution of masters and doctors working professionally at the institution analyzed, as well as in the age of the students. In the 20 years of the second half, there were differences between masters and PhD working professionally in the institution itself, as they came from private universities, they are women and PhD. Conclusions: The changes in the profile of masters and PhD that graduated from this PGP in cardiology reflect transformations that occurred in the job market and academy over the decades.

CO2 emissions into the atmosphere have been rapidly rising due to human activities, resulting in the escalation of global warming. To mitigate climate change, it is imperative to develop materials for CO2 capture with high CO2 capacity and low production costs. Herein, we developed a facile method to obtain adsorbents based on reduced graphene oxide (rGO) sheets, NrGO(1 – X)700, where X represents the mass of diethylenetriamine (DETA) (X = 1, 2 and 4 g) used in the preparation. The materials NrGO(1 – 1)700, NrGO (1 – 2)700, and NrGO(1 – 4)700 were obtained from graphene oxide dispersions, followed by DETA impregnation and chemical activation with K2CO3. N2 isotherms demonstrated that the materials simultaneously presented micro and mesopores with similar values of specific surface area (280.16 to 310.32 m2 g–1), pore volume (0.26 to 0.28 cm3 g–1) and pore size (3.78 to 3.80 nm). CO2 sorption experiments revealed that the material NrGO(1 – 4)700, containing the highest amount of pyridinic, graphitic, and amino nitrogen functionalities, showed the best CO2 adsorption capacity. Diffuse reflectance Fourier transformed infrared spectroscopy experiments indicated stronger solid-gas interactions for NrGO(1 – 4)700 than for the other materials.

Foram selecionadas cinco árvores de cada espécie, com a idade de 9 anos, sendo coletadas amostras a 1,30 m do solo para análise das características anatômicas e das propriedades físicas da madeira. As variáveis anatômicas, com exceção do comprimento da fibra e da espessura da parede celular, correlacionaramse com as propriedades físicas da madeira e influenciaram seus valores. Quanto maior a fração da parede celular (0,79), frequência de vaso (0,44) e frequência de raio (0,92), maior a densidade básica da madeira. Quanto maior o diâmetro da fibra (0,94), diâmetro do lume da fibra (0,88), diâmetro do vaso (0,88), altura de raio (0,86) e largura do raio (0,84), maior o teor de umidade da madeira. material Benth.

ABSTRACT When the premise is the best final use of wood, evaluation of anatomical variables is recommended, bearing in mind that they are correlated with the properties of this material. The present study aimed to evaluate the correlation between anatomy and the physical properties of wood from Parapiptadenia rigida (Benth.) Brenan, Peltophorum dubium (Spreng.) Taub., Eucalyptus grandis W. Hill × Eucalyptus urophylla S.T. Blake (hybrid) and Schizolobium parahyba (Vell.) Blake, from an agroforestry system. For this purpose, five trees of each species, aged 9 years old, were selected, and samples were collected from the diameter at 1.30 m height from the ground for analysis of the anatomical characteristics and physical properties of the wood. Anatomical variables, with the exception of fiber length and cell wall thickness, correlated with the physical properties of wood and influenced their values. The higher the cell wall fraction (0.79), vessel frequency (0.44) and ray frequency (0.92), the greater the basic density of the wood. The greater the fiber diameter (0.94), lumen diameter (0.88), vessel diameter (0.88), ray height (0.86) and ray width (0.84), the higher the moisture content of the wood. recommended material Benth.

Abstract The presence of spoilage microorganisms in forage interferes with the fermentation process of silage, due to competition with lactic acid bacteria for substrate, generating losses and influencing the nutritional value of the ensiled material. Thus, the objective is to evaluate the effect of “Alecrim Pimenta” essential oil (Lippia sidoides) and nanoformulated thymol on microbiological, fermentative and aerobic stability profile of sorghum (Sorghum bicolor cv. BRS Ponta Negra) silage intercropped with Paiaguás grass (Urochloa brizantha cv. BRS Paiaguás). A 4 x 3 factorial design was adopted, with four additives applied to the silages (control treatment; nanoformulated "Alecrim Pimenta" essential oil (OEN); 62% nanoformulated thymol; and 100% pure nanoformulated thymol), associated with three silo period times (15, 30 and 45 days), with five replications per treatment, totaling 60 mini silos. The Clostridium population was higher in the control treatment and in the OEN. The Lactobacillus population decreased with the increase in silo opening time. Higher aerobic stabilities were recorded in silages with 100% nanoformulated thymol with opening at 15 days; and silages with 62% nanoformulated Thymol (opening period at 30 and 45 days). Silages with 100% thymol provided higher losses of dry matter, gases and effluents, while the use of OEN provided lower losses of dry matter and gases. Silos opened at 45 days showed higher losses of dry matter, gases and effluents. Sorghum and Paiaguás grass silages that received nanoformulated thymol were more efficient in controlling Clostridium and Lactobacillus populations, and this additive improved the aerobic stability of the silage. substrate material Thus Alecrim Pimenta Lippia sidoides microbiological cv Negra Urochloa Paiaguás. .

Resumo A presença de microrganismos deterioradores na forragem interfere no processo fermentativo da silagem, devido a competição com as bactérias ácido láticas por substrato, gerando perdas e influenciando o valor nutritivo do material ensilado. Assim, objetiva-se avaliar o efeito do óleo essencial de Alecrim pimenta (Lippia sidoides) e do timol nanoformulado sobre perfil microbiológico, fermentativo e estabilidade aeróbia de silagem do consórcio de Sorgo (Sorghum bicolor var. Ponta Negra) com capim Paiaguás (Urochloa brizantha cv. Paiaguás). Foi adotado esquema fatorial 4 x 3, quatro aditivos aplicados nas silagens (tratamento controle; óleo essencial de Alecrim pimenta nanoformulado (OEN); timol nanoformulado 62%; e timol nanoformulado 100% de pureza), associados a três tempos de abertura do silo (15, 30 e 45 dias), com cinco repetições por tratamento, totalizando 60 mini silos. A população de Clostridium foi maior no tratamento controle e no OEN. A população de Lactobacillus reduziu com o aumento no tempo de abertura do silo. Maiores estabilidades aeróbica foram registradas em silagens com timol nanoformulado 100% com abertura aos 15 dias; e silagens com Timol nanoformulado 62% (tempos de abertura aos 30 e 45 dias). Silagens com timol 100% proporcionaram maiores perdas de matéria seca, gases e efluentes, enquanto que o uso de OEN proporcionou menores perdas de matéria seca e gases. Silos com abertura aos 45 dias apresentaram maiores perdas de matéria seca, gases e efluentes. Silagens de Sorgo e capim Paiaguás que recebram timol nanoformulado foram mais eficientes em controlar as populações de Clostridium e Lactobacillus, bem como este aditivo melhorou a estabilidade aeróbica da silagem. substrato ensilado Assim objetivase objetiva se Lippia sidoides microbiológico Sorghum var Negra Urochloa cv Paiaguás. .

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 A flexibilidade está relacionada com propriedades específicas teciduais que permitem a amplitude máxima de movimento articular sem a presença de lesão. O presente estudo teve como objetivo identificar e sintetizar as evidências sobre a prevalência de níveis adequados de flexibilidade em crianças e adolescentes brasileiros (6 a 19 anos). Foi realizada uma busca sistematizada de estudos publicados de 2009 a 2019 em seis bases de dados (MEDLINE/PubMed; Scopus; SportDiscus; LILACS; Web of Science; SCIELO). Foram incluídos 14 estudos que compilaram dados de 11.666 participantes em sete estados brasileiros diferentes. Todos os estudos realizaram teste de sentar e alcançar para avaliar a flexibilidade. Dentre todas as crianças e adolescentes dos estudos analisados, 58,9% do total (62,0% dos meninos e 50,9% das meninas) apresentaram flexibilidade adequada. Concluímos que mais da metade das crianças e adolescentes brasileiros possuem flexibilidade adequada para a saúde.

abstract Flexibility is related to specific tissue properties of the body, which aim to determine the maximum range of motion of the joints without injury. This study aimed to identify and summarize the evidence on prevalence of adequate levels of flexibility in Brazilian children and adolescents (6 to 19 years old). We performed a systematic search of studies published from 2009 to 2019 in six databases (MEDLINE/PubMed; Scopus; SportDiscus; LILACS; Web of Science; SCIELO). Fourteen studies that compiled data from 11,666 participants in seven different Brazilian states were included. All studies conducted sit and reach tests to assess flexibility. Among all the children and adolescents in the analyzed studies, 58.9% of the total (62.0% of boys and 50.9% of girls) had adequate flexibility. We conclude that more than half of Brazilian children and adolescents have adequate flexibility for health.

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.

Resumo A obesidade representa um dos principais fatores de risco cardiovascular. Sendo que esta apresenta uma elevada prevalência entre a população brasileira. O objetivo do estudo foi avaliar o índice de adiposidade corporal (IAC) e os fatores associados em trabalhadores do setor moveleiro. Foi realizado um estudo descritivo com 204 trabalhadores do pólo moveleiro da cidade de Ubá-MG, de ambos os sexos, com idade entre 20 e 70 anos. Avaliou-se o setor de trabalho, classe econômica, nível de atividade física, índice de massa corporal, circunferência de cintura, circunferência abdominal, relação cintura-quadril, pressão arterial sistólica e diastólica, glicemia de jejum, colesterol total, lipoproteína de alta densidade, lipoproteína de baixa densidade e triglicerídeos. A razão de chances (RC) foi utilizada para determinar a força de associação entre as variáveis. Do total de avaliados, 50% apresentaram o IAC elevado, com estes apresentando maiores valores antropométricos, pressóricos, glicemia e triglicerídeos (p<0,05). Pode-se observar que a idade elevada (RC: 2,76; p= 0,002) e o setor de produção (RC: 2,52; p= 0,045) foram significativamente associados a mesma. Quando analisado o IAC segundo a classe econômica e nível de atividade física, foi observado um aumento do IAC com a redução da classe econômica. Conclui-se que foi encontrado um elevado percentual de IAC elevado entre os trabalhadores, com associação deste com a idade, setor de trabalho e classe econômica dos mesmos.

Abstract Obesity represents one of the main cardiovascular risk factors with high prevalence among the Brazilian population. The aim of this study was to assess body adiposity index (BAI) and associated factors in workers of the furniture sector. A descriptive study was conducted with 204 workers of the furniture sector in the city of Ubá-MG of both sexes aged 20-70 years. Working sector, economic class, level of physical activity, body mass index, waist circumference, abdominal circumference, waist-to-hip ratio, systolic and diastolic blood pressure, fasting glycemia, total cholesterol, high density lipoprotein, low density lipoprotein and triglycerides were assessed. Odds ratio (RC) was used to determine the strength of association among variables. Of the total number of individuals assessed, 50% had high BAI, presenting higher anthropometric, blood pressure, glucose and triglyceride values (p <0.05). It was observed that advanced age (RC: 2.76; p = 0.002) and production sector (RC: 2.52; p = 0.045) were significantly associated with BAI. According to economic class and level of physical activity, increase in BAI was observed with reduction of economic class. It could be concluded that high percentage of increased BAI was found among workers, with association with age, working sector and economic class.
