Abstract The objective of this work was to determine the effect of solar radiation intensity of the grazing system on sheep behavior. Treatment 1, consisted of monoculture of natural grasses (47 ± 5 lux), treatment 2 of natural grasses with Leucaena leucocephala trees (34 ± 3 lux) and treatment 3 of natural grasses with Manguifera indica trees (16 ± 3 lux). The total time of each activity per daily session was determined. A completely randomized design was used with a 3x2 factorial arrangement (three intensities of solar radiation, two sessions per day). Grazing behavior was affected by the interaction between factors. The grazing-walking activity was higher in the pastures with lower levels of solar radiation (Leucaena y Manguifera), with 217.50 y 216.38 min, respectively, in the morning session, while all times were lower in the afternoon session, with the lowest result in grazing in the sun (108.05 minutes). The reduction of solar radiation under the treetops favored the behavior of the sheep, which allowed the animals to perform resting and ruminating activities under the shade of the trees, more preferably in the afternoon session.

Resumen El objetivo fue determinar el efecto de la intensidad de radiación solar del sistema de pastoreo en la conducta de ovinos. El tratamiento 1 consistió en: monocultivo de gramíneas naturales (47 ± 5 lux); el 2: gramíneas naturales con árboles de Leucaena leucocephala (34 ± 3 lux); y el 3: gramíneas naturales con árboles de Manguifera indica (16 ± 3 lux). Se determinó el tiempo total de cada actividad por sesión del día. Se utilizó un diseño completamente aleatorizado, con arreglo factorial 3x2 (tres intensidades de radiación solar por dos sesiones del día). La conducta en pastoreo fue afectada por la interacción entre los factores. La actividad pastar-caminar fue mayor en los pastoreos de menor nivel de radiación solar (Leucaena y Manguifera) con 217.50 y 216.38 min respectivamente, en la sesión de la mañana; mientras que todos los tiempos fueron menores en la sesión tarde, con el menor resultado en el pastoreo al sol (108.05 minutos). La reducción de la radiación solar bajo la copa de los árboles favoreció el comportamiento conductual de las ovejas, esto permitió que los animales realizaran actividades de descanso y rumia bajo la sombra de los árboles, con más preferencia en la sesión tarde.

Abstract Objective: To examine if the substitution of different screen time intervals with light physical activity (LPA), moderate to vigorous physical activity (MVPA) and sleep is associated with cardiovascular indicators and inflammatory markers in children. Methods: This is a cross-sectional study developed with 186 children aged between six and 11 years old from public schools in southern Brazil. CRF was measured with the 6-minute running and walking test, following the Brazil Sports Project procedures. The percentage of fat was evaluated through DXA. LPA and MVPA were measured using accelerometers. Sleep and screen time were assessed by questionnaires answered by parents. Leptin and C-reactive protein were measured by fasting blood collection. Systolic and diastolic blood pressure were determined through a digital sphygmomanometer. Isotemporal substitution models were used for statistical analysis. Results: Replacing 1 h of screen time with MVPA was associated with lower BMI, systolic and diastolic blood pressure, fat percentage, leptin, and C-reactive protein. When screen time was substituted for sleep time, lower waist circumference was observed. Regarding the substitution of 1 h of screen time with LPA, significant values were found only for leptin. Conclusion: The replacement of screen time with physical activities of different intensities and sleep time was associated with benefits in cardiovascular indicators and inflammatory markers in childhood.

Resumo A etologia dos insetos é um fator importante quando se deseja relizar manejo de pragas. Através deste conhecimento, é possível manipular atividades comportamentais, repelir, ou atrair os insetos de acordo com as necessidades e interesses. O gorgulho do milho Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae), uma das principais pragas de grãos armazenados tem sido alvo de estudos de alterações comportamentais através de substâncias naturais devido à sua resistência a diferentes classes de insecticidas. Assim, este estudo teve como objetivo avaliar o efeito de concentrações subletais de extrato de neem e do óleo de copaíba sobre o comportamento de movimentação de S. zeamais. As características comportamentais consideradas foram: a atividade de caminhamento, a frequência do contato dos insetos com a massa de grãos tratada, e o tempo gasto para realização destes comportamentos. A atividade de caminhamento do S. zeamais aumentou quando os insetos foram expostos ao extrato de Neem e ao óleo de copaíba. Em geral, o extrato de Neem e o óleo de Copaíba induziram mais contato com a massa de grãos do que o controle, sugerindo um efeito atrativo sobre o inseto, contudo este efeito foi mais significativo para o óleo de Neem. O comportamento do inseto foi alterado, apresentando um caminhamento específico devido aos estímulos do óleo de copaíba e do extrato de Neem. Estes resultados indicam que o óleo de copaíba e o extrato de Neem podem ser alternativas potenciais para o controle do S. zeamais em produtos armazenados, uma vez que alterações no comportamento desta praga podem reduzir os danos qualitativos e quantitativos nos grãos. Assim, o desenvolvimento de produtos baseados no óleo de copaíba e no extrato de Neem pode ser útil para o manejo de pragas de armazenamento.

Abstract Insects' ethology is an important factor when it is desired to carry out pest management. This knowledge makes it possible to manipulate behavioral activities, repel, or attract insects according to needs and interests. The maize weevil Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae), one of the main stored grain pests, has been the target of studies of behavioral changes studies through natural substances due to its resistance to different insecticidal classes. Thus, this study aimed to evaluate the effect of sublethal concentrations of neem extract and copaiba oil on the locomotor behavior of S. zeamais. The behavioral characteristic considered were walking activity, the frequency of contact of insects with the treated grain mass, and the time spent for this behavior. The walking activity of the S. zeamais increased with exposure to Neem extract and Copaiba oil. In general, the Neem extract and Copaiba oil-induced more contact with grain mass than the control, suggesting an attractive effect on the insect, however more significant for the Neem oil. The insect's behavior was altered, presenting a specific path due to Copaiba oil and Neem extract stimuli. These results indicate that Copaiba oil and Neem extract can be a potential alternative for controlling S. zeamais on stored products since changes in this pests' behavior can reduce qualitative and quantitative grain damage. Thus, the development of products based on Copaiba oil and Neem extract may be helpful for storage pest management.

Resumen Introducción: Frente al COVID-19 se adoptaron medidas de restricción social que influyeron en los hábitos de vida de la población, aumentando el sedentarismo. Considerando la alta complejidad y la dedicación exigida por la carrera de Medicina, se torna relevante investigar el efecto pandémico sobre la práctica de ejercicio físico y la conducta sedentaria de estos estudiantes. Objetivos: Identificar los cambios en la actividad física y en la conducta sedentaria auto-reportados por los estudiantes de Medicina de la ciudad de Salvador, Bahía, Brasil, antes y durante el auto-confinamiento impuesto por la pandemia de COVID-19. Métodos: Estudio longitudinal, prospectivo, cuantitativo, realizado con estudiantes de medicina regularmente matriculados, mayores de 18 años. Foi aplicado um questionário virtual, estruturado, anónimo, autocompletado, contendo aspectos sociodemográficos e académicos. Além disso, foi aplicado o International Physical Activity Questionnaire (IPAQ), em sua versão curta, considerando o período antes e durante a pandemia. A través de éste, se midió el nivel de actividad física, el comportamiento sedentario y el tiempo dedicado a caminar, así como las actividades moderadas y vigorosas. Resultados: Se incluyeron 268 estudiantes de medicina, predominantemente mujeres (65,7%), blancas (50,0%) y morenas (38,8%), de 24,2 ± 5,5 años de edad, solteras (90,7%), en el ciclo clínico (59,0%), en instituciones privadas (78,4%). No se identificaron diferencias estadísticamente significativas en el nivel de actividad física y el tiempo dedicado a actividades moderadas y vigorosas. Sin embargo, hubo una reducción en el tiempo de caminata (p<0,00001) y un aumento en la conducta sedentaria (p=0,001) durante la pandemia COVID-19, siendo mayor el impacto entre las mujeres (p=0,0009). Conclusión: Las repercusiones de la pandemia COVID-19 se manifestaron en el aumento de la conducta sedentaria entre los estudiantes de medicina, especialmente entre las mujeres, además de la reducción del tiempo de actividad dedicado a caminar. Son necesarios estudios longitudinales para analizar las consecuencias a medio y largo plazo de este cambio en los hábitos de vida saludables de los estudiantes de medicina.

ABSTRACT Introduction: In order to face COVID-19, social restriction measures were adopted that influenced the population's living habits, increasing sedentary lifestyle. Considering the high complexity and dedication required by the Medicine course, it becomes relevant to investigate the effect of the pandemic on the practice of physical exercise and sedentary behavior of these students. Objective: Identify changes in physical activity and sedentary behavior self-reported by medical students in the city of Salvador, Bahia, before and during the self-confinement imposed by the COVID-19 pandemic. Methods: Longitudinal, prospective, quantitative study carried out with regularly enrolled medical students over 18 years of age. A virtual, structured, anonymous, self-completed questionnaire was applied, containing sociodemographic and academic aspects. In addition, the International Physical Activity Questionnaire (IPAQ) was applied in its short version, considering the period before and during the pandemic. Through this, the level of physical activity, sedentary behavior and time spent walking and performing moderate and vigorous activities were measured. Results: 268 medical students were included, predominantly women (65.7%), white (50.0%) and mixed race (38.8%), aged 24.2 ± 5.5 years, single (90.7%), attending the clinical cycle (59.0%), in private institutions (78.4%). No statistically significant differences were identified in the level of physical activity and in the time spent with moderate and vigorous activities. However, there was a reduction in walking time (p<0.00001) and an increase in sedentary behavior (p=0.001) during the COVID-19 pandemic, with the greatest impact among women (p=0.0009). Conclusion: The repercussions of the COVID-19 pandemic have been shown to increase the sedentary behavior of medical students, especially among women, and to reduce activity time spent with walking. Longitudinal studies are needed to analyze the medium and long-term consequences of this change in the healthy lifestyle habits of medical students.

ABSTRACT Anatomical and ultrasonographic diagnostic work-up of testicular abscesses (n = 2) and testicular microlithiasis (n = 3) in Kazakh rams is described. For testicular abscesses, the localized symptoms include enlargement of the testicle and decreased elasticity, accompanied by varying degrees of pain and fever, abnormal behavior, walking or urinating with legs spread apart and accompanied by painful moans. Ultrasound findings: several hypoechoic or fluid dark areas with irregular morphology appear within the testicular parenchyma, with unclear borders with the surrounding normal tissues and uneven internal echogenicity. An autopsy revealed unilateral caseous necrosis with degeneration of all testicular tissues. Testicular microlithiasis does not present clinically and normal semen quality is not affected. Ultrasound findings: sparse, scattered, or dense punctate, pinpoint-like echogenic dots, some with comet tail signs and no acoustic shadow, are seen in the testicular parenchyma. The routine treatment for testicular abscesses is surgical drainage, but when degeneration and necrosis of testicular tissue occur, leading to severe systemic symptoms, the animal must be put down. Testicular microlithiasis is relatively rare and there are no effective treatments or interventions available, but it remains a potential contributor to testicular dysfunction and other secondary conditions. workup work up n 2 3 described elasticity fever behavior moans findings parenchyma echogenicity affected sparse scattered punctate pinpointlike pinpoint like dots shadow drainage occur down available conditions

RESUMO Descreveu-se o diagnóstico anatômico e ultrassonográfico de abscessos testiculares (n = 2) e microlitíase testicular (n = 3) em carneiros do Cazaquistão. No caso de abscessos testiculares, os sintomas localizados incluem aumento do testículo e diminuição da elasticidade, acompanhados de vários graus de dor e febre. Observou-se comportamento anormal, com o animal andando ou urinando com as pernas abertas, acompanhado de gemidos dolorosos. Achados ultrassonográficos: várias áreas hipoecogênicas ou escuras fluidas com morfologia irregular aparecem no parênquima testicular, com bordas pouco nítidas, com os tecidos normais circundantes e ecogenicidade interna irregular. Uma autópsia revelou necrose caseosa unilateral com degeneração de todos os tecidos testiculares. A microlitíase testicular não se apresenta clinicamente e a qualidade normal do sêmen não é afetada. Achados ultrassonográficos: pontos ecogênicos esparsos, dispersos ou densos, pontilhados, semelhantes a alfinetes, alguns com sinais de cauda de cometa e sem sombra acústica, são vistos no parênquima testicular. O tratamento de rotina para abscessos testiculares é a drenagem cirúrgica, mas, quando ocorre degeneração e necrose do tecido testicular, levando a sintomas sistêmicos graves, o animal deve ser eliminado. A microlitíase testicular é relativamente rara e não há tratamentos ou intervenções eficazes disponíveis, no entanto continua sendo um possível contribuinte para a disfunção testicular e outras condições secundárias.

Abstract The presence of land use mix (LUM) in a neighborhood has been shown as an important aspect to promote walking as a daily means of transport. However, few studies in the area have applied different measurement strategies to test their effect on alternative modes of travel behavior, such as older adults walking. We applied six LUM measures of land use mix in two neighborhood definitions (500 and 1000m network buffers) and assessed their associations with walking for transport outcomes in adults over age 60 years from the EpiFloripa Aging study, living in the municipality of Florianópolis, Brazil, in 2013/14. Accounting for sociodemographic and environmental variables, adjusted associations found a positive relationship between four LUM and walking. The entropy index and three alternative measures defined by the intensity of commercial and nonresidential uses were positively associated with the walking for transportation, regardless of neighborhood definition. Stronger positive associations were seen when using smaller buffers and measures of the proportion of commercial uses, proportion of nonresidential uses and destination density. The results show that alternative measurements can overcome the entropy index, pointing out the need to adapt LUM measures and neighborhood scale to the geographic context and age group under analysis.

Resumo A presença de diferentes usos do solo em um bairro tem se mostrado um aspecto importante para promover a caminhada como meio de transporte diário. No entanto, poucos estudos na área aplicaram diferentes estratégias de mensuração para testar seu efeito em modos alternativos de comportamento de viagem, como a caminhada de idosos. Aplicamos seis medidas de uso do solo em duas definições de bairro (buffers de rede de 500 e 1000m) e avaliamos suas associações com a caminhada para fins de transporte em participantes (≥ 60 anos) do estudo EpiFloripa Idoso (2013/14) de Florianópolis, Brasil. Considerando variáveis sociodemográficas e ambientais, as associações ajustadas encontraram uma relação positiva entre quatro medidas e a caminhada. O índice de entropia e três medidas alternativas de intensidade de usos não residenciais associaram-se positivamente com a caminhada para transporte, independentemente da definição de bairro. Associações positivas mais fortes foram observadas ao usar buffers menores e medidas de proporção de usos comerciais, proporção de usos não residenciais e densidade de destinos. Os resultados mostram que medidas alternativas podem superar o índice de entropia, apontando a necessidade de adaptação das métricas e da escala de vizinhança ao contexto geográfico e à faixa etária em análise. diário entanto viagem idosos 50 1000m m ≥ ( 6 anos 2013/14 201314 2013 14 (2013/14 Florianópolis Brasil ambientais associaramse associaram comerciais destinos análise 5 2013/1 20131 201 1 (2013/1 2013/ 20 (2013/ 2 (2013 (201 (20 (2

Abstract Background: This study aimed to investigate the analgesic impact of S(+)-ketamine on pain behavior and synovial inflammation in an osteoarthritis (OA) model. Methods: Animals were grouped as follows: OA-Saline (n = 24) and OA-Ketamine (n = 24), OA induced via intra-articular sodium monoiodoacetate (MIA); a Non-OA group (n = 24) served as the control. On the 7th day post OA induction, animals received either saline or S(+)-ketamine (0.5 mg.kg–1). Behavioral and histopathological assessments were conducted up to day 28. Results: S(+)-ketamine reduced allodynia from day 7 to 28 and hyperalgesia from day 10 to 28. It notably alleviated weight distribution deficits from day 10 until the end of the study. Significant walking improvement was observed on day 14 in S(+)-ketamine-treated rats. Starting on day 14, OA groups showed grip force decline, which was countered by S(+)-ketamine on day 21. However, S(+)-ketamine did not diminish synovial inflammation. Conclusion: Low Intra-articular (IA) doses of S(+)-ketamine reduced MIA-induced OA pain but did not reverse synovial histopathological changes. IRB approval number: 23115 012030/2009-05.

Resumo A migração de aves é um fenômeno que leva milhares de indivíduos a se deslocarem entre diferentes áreas de alimentação e reprodução, podendo esses movimentos ultrapassarem fronteiras geopolíticas. Este é um comportamento crucial para a sobrevivência de muitas espécies. No entanto, os impactos antrópicos estão afetando os habitats das espécies, contribuindo para o declínio populacional das aves. Diante disto, este estudo teve como objetivo analisar os distúrbios causados pelas atividades turísticas sobre as aves migratórias que visitam os estuários dos rios Cardoso e Camurupim, no litoral do estado do Piauí, e propor medidas para mitigar as perturbações sobre as aves. As amostragens foram realizadas em três pontos de observação, onde foram analisadas as alterações do comportamento das aves em repostas às atividades turísticas. Para isto, foram utilizados binóculos, câmera fotográfica e um telêmetro a laser para auxiliar na elaboração das zonas de impacto. Embora ocorram diversos tipos de atividades turísticas na região, as principais perturbações são causadas pelo kitesurf e turistas caminhando próximo às áreas de alimentação ou repouso das espécies. Calidris minutilla, Calidris pusilla, Calidris alba, Actitis macularius e Charadriius semipalmatus foram as espécies menos sensíveis aos distúrbios, reagindo com mais frequência dentro das zonas de impactos Z = 0-30m e Z = 30-60m, ao passo que as espécies Pluvialis squatarola, Numenius hudsonicus, Tringa melanoleuca, Calidris canutus, Limnodromus griseus e Pandion haliaetus apresentaram maiores distâncias de fuga. Os resultados deste estudo mostram que a presença de turistas caminhando e a prática do kitesurf são as principais atividades que impactam as aves migratórias na região, o que demonstra a necessidade de medidas para mitigar tais impactos. Com base nos resultados deste estudo, a criação de zonas de proteção mínima de 160m e 200m são indicadas para mitigar os distúrbios provocados pela aproximação de banhistas e kitesurfistas. reprodução geopolíticas entanto disto Camurupim Piauí observação isto binóculos impacto região minutilla pusilla alba 030m m 0 30m 3060m, 3060m 30 60m, 60m 30-60m squatarola hudsonicus melanoleuca canutus fuga kitesurfistas 3

Abstract The bird migration phenomenon makes thousands of individuals displace between different sites for feeding and breeding purposes. These displacements often make these birds cross geopolitical borders. This behavior is crucial for the survival of many species; however, anthropogenic impacts affect their habitats and contribute to bird-population decline. In light of the foregoing, the aims of the present study are to analyze disturbances caused by touristic activities over migratory birds who visit the estuaries of Cardoso and Camurupim rivers on the coast of Piauí State, and to suggest measures aimed at mitigating disturbances over birds. Samples were collected at three observation points to analyze changes in bird behavior, in response to touristic activities in these sites. Binoculars, a camera and a laser rangefinder were used to help drawing impact zones. Although several touristic activities are performed in the herein assessed region, the main disturbance in it is caused by both kitesurf practitioners and tourists who walk by these species’ feeding or resting zones. Calidris minutilla, Calidris pusilla, Calidris alba, Actitis macularius and Charadriius semipalmatus were the species least sensitive to disturbances, and they more often reacted to them within impact zones Z = 0-30m and Z = 30-60m, whereas species Pluvialis squatarola, Numenius hudsonicus, Tringa melanoleuca, Calidris canutus, Limnodromus griseus and Pandion haliaetus flee to distances. Based on the current results, kitesurfing and tourists walking by these sites account for the main impact on migratory birds in this region. This finding highlights the need of taking measures to mitigate such impacts. Accordingly, creating minimum protection zones to cover distances ranging from 160m to 200m radius is a recommendation to mitigate disturbances caused by bathers and kitesurf practitioners’ approaching. purposes borders however birdpopulation population decline foregoing State Binoculars region minutilla pusilla alba 030m m 0 30m 3060m, 3060m 30 60m, 60m 30-60m squatarola hudsonicus melanoleuca canutus results Accordingly approaching 3

Abstract Telenomus remus (Hymenoptera: Scelionidae) is an efficient parasitoid of Spodoptera eggs. However, biological control programs require taxonomic, bioecological and behavioral studies of biological agents. Although the performance of T. remus in pest control has been evaluated, little is known about its behavioral aspects that can influence IPM tactics. The aim of this study was therefore to study the parameters related to the oviposition behavior of T. remus on Spodoptera frugiperda (Lepidoptera: Noctuidae) eggs. The experiment was conducted in the laboratory, where 17 females were transferred individually to arenas containing a mass of S. frugiperda eggs. Oviposition behavior was recorded for 30 minutes. The average walking speed of the females was 0.116 mm.s-1 and the total distance covered was 203.3 mm. The females remained on the egg masses for an average of 16.7 min, which corresponds to more than half of the total time. The average number of parasitized eggs was 15.1 per female in 30 minutes. Females with larger antennae had lower values for average speed and total distance covered. The results of the parameters evaluated show the standard oviposition behavior of T. remus females on S. frugiperda eggs and help us to better understand the species.

ABSTRACT Objective: The aim of this study was to evaluate the behavior and performance of steers in two different housing areas (10 vs. 100 m2/animal) and two feeding models (daily supply vs. self-feeding) during the fattening period. Materials and methods: Forty-eight Hereford steers with initial live weight (LW): 214,0 kg were housed under four treatments: 100DS (100 m2/animal and daily supply), 100SF (100 m2/animal and self-feeding), 10DS (10 m2/animal and daily supply), 10SF (10 m2/animal and self-feeding) until reaching a final LW of 370 - 390 kg. Behavior was recorded by observation. Dry matter intake (DMI) and average daily gain (ADG) were recorded to estimate feed conversion ratio (FCR). Back fat thickness (BFT) and Longissimus muscle area (LMA) were measured. Steers were sent to a commercial abattoir to evaluate carcass yield. Results: The frequency of rest and walking was higher in steers in the largest housing area. Self-feeding contributed to the intake distribution during the day. No differences were detected in DMI, ADG and FCR. However, the confined animals (10DS and 10SF) produced more BFT and less LMA. In addition, they had less carcass yield at slaughter. Conclusions: Therefore, a larger housing area and the self-feeding model could contribute to express steers’ natural behavior and improve their performance.

RESUMEN Objetivo: EL propósito de este estudio es evaluar el comportamiento y desempeño de bueyes en dos zonas de estancia (10 vs. 100 m2/animales) y dos modelos de alimentación (suplementación diaria vs autoalimentación) durante el periodo de ceba. Materiales y métodos: Se emplearon un total de 48 bueyes Hereford con un peso inicial (PI) de 214,0 kg con dos tratamientos diferentes: 100 SD (100 m2/animal y suplementación diaria), 100 AA (100 m2/animal y auto alimentación), 10 SD (10 m2/animal y suplementación diaria), 10 AA (10 m2/animal y auto alimentación) hasta alcanzar un peso final (PF) de 370 - 390 kg. Se registró el comportamiento mediante observación. Igualmente, se registró el consumo de materia seca (CMS) junto a la ganancia promedio diaria (GPD) para estimar la relación de conversión alimentaria (RCA). Se midieron el grosor de la grasa posterior (GGP) y la zona muscular Longissimus (ZML) y se enviaron los bueyes al matadero para evaluar el rendimiento de la canal. Resultados: La frecuencia de descanso/marcha fue mayor en los bueyes que permanecieron en la mayor área de estancia. La auto alimentación contribuyó a distribuir el consumo de alimentos durante el día. No se detectaron diferencias en CMS, GPD y RCA. Sin embargo, los animales confinados (10 SD y 10 AA) produjeron más GGP y menos de ZML. Por otra parte, mostraron un menor rendimiento de la canal durante el sacrificio. Conclusiones: Un área de estancia mayor, junto al modelo de autoalimentación, contribuyó a un comportamiento natural de los bueyes y un mejoramiento de su desempeño.

Abstract Introduction: Morbid obesity is associated with alterations in the ability to walk, however, the behavior of the 6-minute walk test in subjects with increases in body mass index is unknown. Objective: To describe the behavior of the 6-minute walk test in subjects with normal body mass index to morbid obesity. Methods: Through an analytical cross-sectional design, subjects of both genders from 18 to 60 years old with body mass index were studied: Normal (BMI: 18.5-24.9); overweight (BMI: 25-29.9); obesity (BMI: 30-39.9); morbid obesity (BMI: > 40) kg/m2. A 6-minute walk test was performed, demographic variables and pathological personal history were delimited. BMI categories were analyzed with one-way ANOVA and Bonferroni adjustment, and gender with t-test, both for independent groups, and Pearson's correlations for the various variables. Results: 480 subjects of both genders were studied in four groups. Age: men 43 ± 11 and women 45 ± 10 years old. Percentage diabetes mellitus (6.7%), arterial hypertension (18.3%). Meters walked men vs. women by body mass index (normal: 483 ± 56 vs. 449 ± 61; overweight: 471 ± 55 vs. 441 ± 44; obesity: 455 ± 70 vs. 421 ± 47; morbid obesity: 443 ± 49 vs. 403 ± 54, p < 0.05). Correlation body mass index-meters walked: r: -0.446 (p < 0.0001). Conclusions: Meters walked in the 6-minute walk test decreased as body mass index increased. The male gender walked more meters in all categories.

Abstract Despite the growing number of research that analyzes the built environment as a support for walking, there are still doubts about the delimitation of the area of influence of this behavior. The use of census tracts is justified by the wide availability of sociodemographic data; however, they have been shown to be fragile for assessing walkability. This article aimed to compare 8 different types of spatial units to verify which ones are better suited to the evaluation of walkability of a Brazilian city, correlating a synthetic walkability index and its component variables with walking frequencies obtained from a recent origin-destination survey. The results showed that the macrozones, the zones of similar sizes (400 m), the grouping by market value, and by topological accessibility showed greater correlations with the levels of walking and that there is a clear dependence of the statistics on the scale of the units and their delimitation, reaffirming the problem of the modifiable areal unit problem (MAUP). The research can contribute to the refinement of spatial methods for walkability assessment, advancing toward a more adequate view of walkability in Brazilian cities. behavior data however city origindestination origin destination survey macrozones 400 (40 m, m , m) value MAUP.

ABSTRACT BACKGROUND: Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults. DESIGN AND SETTING: Cross-sectional observational analysis of baseline data as part of the Remobilize Study. METHODS: Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility. RESULTS: A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25–19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00–28.32), comorbidity (OR: 5.11; CI 3.44–7.81), pain (OR: 4.56; CI 3.33–6.28), total walking (OR: 0.99; CI 0.99–1.00), SB of 8–10 hours (OR: 1.85; CI 1.15–2.93), and SB of > 10 hours (OR: 3.93; CI 2.48–6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96–0.98). P < 0.05. CONCLUSIONS: During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.

Abstract Introduction Low-level physical activity and sedentary behavior are factors that can impact the fear of falling and risk of falls in older adults. Objective This study aimed to determine whether the duration and frequency of physical activity and sedentary behavior predict the fear of falling and risk of sarcopenia in older people. Methods This was a cross-sectional study with 116 older individuals from southern and southeastern Brazil. A sociodemographic and health questionnaire, the International Physical Activity Questionnaire (IPAQ – short version), the Falls Efficacy Scale – International (FES-I), and the SARC-f were used. Data were analyzed by bootstrapping procedures, Pearson's correlation, and regression analysis (p < 0.05). Results Walking days (β = -0.38; p < 0.001) and moderate activity days (β = -0.23; p < 0.001) showed a negative prediction of fear of falling. Walking days also had a significant and negative prediction of the risk of sarcopenia (β = -0.34; p < 0.001). Conclusion We conclude that weekly walking and the practice of moderate-intensity physical activity negatively predict the fear of falling in older adults. Weekly walking also negatively predicts the risk of having sarcopenia. Sedentary behavior was not a predictor of fear of falling and risk of sarcopenia.

ABSTRACT Pair-formation, courtship, copulatory, and post-copulatory behaviors of Eidmanacris meridionalis Desutter-Grandcolas, 1995, were described under laboratory conditions and compared with congeneric species and other Phalangopsidae crickets whose mating behavior has been previously studied. Field observations for the species are also reported. Mating behaviors were observed in E. meridionalis couples: they first remained motionless, and then began walking through the arena screening the substrate. Mating behavior started with antennal contact, followed by males positioning themselves in front of females, that, when receptive, mounted on the males back and started feeding on metanotum secretions of the males. Copulation (female-above-male position) started with the engaging of copulatory structures and stopped with couple detachment. The end-to-end position was observed once, right after couple detachment. Males always remained with the spermatophore, which was eaten after removal or, alternatively, left in the substrate. The main differences in mating behavior of Eidmanacris species regard the mating position and the duration of the reproductive stages, suggesting that other reproductive repertoires can be observed in the genus since 27 species have not yet been studied in regards their reproductive behavior. We can also assume that the morphological, genetic, and chemical diversity found among the species of Phalangopsidae reflects in the behaviors of pair-formation, courtship, copulation, and post-copulation, leading to a diversity of copulation positions, duration of the stages, methods of attracting partners and parental investment. The description of Phalangopsidae mating patterns can provide important information for future evolutionary and phylogenetic studies, apart from useful for distinguishing cryptic species.
