Abstract The aim is to investigate the association between physical activity counseling before and during the Covid-19 pandemic and sociodemographic variables, according to body mass index (BMI) and participation time in the program. A cross-sectional study was conducted with 979 users aged 20 years or older. Before the pandemic, being ≥60 years of age was associated with counseling in users with up to one year of participation in the program. During the pandemic, being ≥60 years of age and having higher education were aspects associated with counseling among participants with normal weight. Furthermore, being separated/widowed among those classified as overweight/obesity, and being female and having higher education among those with up to one year in the program were aspects associated with counseling during the pandemic. Before the pandemic, counseling was associated with age ≥60 years in participants with up to one year in the program. During the pandemic, age ≥60 years and a higher number of years of education were associated with physical activity counseling among those with normal weight. Additionally, being separated/widowed was associated with overweight/obesity. During the pandemic, being female and higher educational attainment were associated with physical activity counseling.

ABSTRACT The São Francisco Submedium Valley in Brazil is the country’s most important table grape exportation region. In 2015, a new pest was reported in the area, the American grapevine moth Lasiothyris luminosa (Razowski & Becker) (Tortricidae), causing significant damage from the bud flowers until the grape berries in the harvesting period. The present work aimed to evaluate artificial diets to guarantee the rearing of L. luminosa in laboratory conditions. Two artificial diets used to rear Anticarsia gemmatalis Hübner and Helicoverpa zea (Boddie) were compared to the species’ natural host (grape berries). It was evaluated the larva, pupal, and larval-pupal period, longevity, fecundity, larval and pupal viability, and sex ratio. L. luminosa completed its cycle in both artificial diets, making it possible to use both to maintain the species in the laboratory. The larval and larval-adult period were shorter for the treatment with A. gemmatalis artificial diet. Also, this diet provided greater pupal viability and higher fecundity. Thus, the A. gemmatalis diet is more indicated to rear L. luminosa in the laboratory than the H. zea diet and grape berries.

ABSTRACT: The present research created a tool to measure ultrasound images of the rib eye area in sheep. One hundred twenty-one ultrasound images of sheep were captured, with regions of interest segmented using the U-Net algorithm. The metrics adopted to evaluate automatic segmentations were Dicescore and intersection over union. Finally, a regression analysis was performed using the AdaBoost Regressor and Random Forest Regressor algorithms and the fit of the models was evaluated using the Mean Square Residuals, mean absolute error and coefficient of determination. The values obtained for the Dice metric were 0.94, and for Intersection over Union it was 0.89, demonstrating a high similarity between the actual and predicted values, ranging from 0 to 1. The values of Mean Quadratic Residuals, mean absolute error and coefficient The determination of the regressor models indicated the best fit for the Random Forest Regressor. The U-Net algorithm efficiently segmented ultrasound images of the Longissimus Dorsi muscle, with greater precision than the measurements performed by the specialist. This efficient segmentation allowed the standardization of rib eye area measurements and, consequently, the phenotyping of beef sheep on a large scale.

RESUMO: O objetivo do presente trabalho foi o de criar uma ferramenta para mensurar imagens ultrassonográficas da área do olho de lombo em ovinos. Foram capturadas 121 imagens ultrassonográficas de ovinos, a partir das quais foram segmentadas regiões de interesse utilizando o algoritmo u-net. As métricas adotadas para avaliar as segmentações automáticas foram Dicescore e Interseção sobre União. Por fim, foi realizada análise de regressão utilizando os algoritmos AdaBoost Regressor e Random Forest Regressor e o ajuste dos modelos foi avaliado por meio de quadrado médio dos resíduos, erro absoluto médio e coeficiente de determinação (R²). Os valores obtidos para a métrica Dice foram 0,94, e para Interseção sobre União foi 0,89, demonstrando uma alta similaridade entre os valores reais e previstos, variando de 0 a 1. Os valores de quadrado médio dos resíduos, erro absoluto médio e coeficiente de determinação do modelo de regressores indicaram o melhor ajuste para o Random Forest Regressor. O algoritmo U-Net segmentou com eficiência as imagens ultrassonográficas do músculo Longissimus Dorsi, com maior precisão que as medidas realizadas pelo especialista. Essa eficiente segmentação permitiu a padronização das medidas de área de olho de lombo e, consequentemente, a fenotipagem de ovinos de corte em larga escala.

Abstract Background: Cardiovascular diseases (CVD) are often influenced by modifiable factors, notably individuals’ lifestyle choices, which play a crucial role in modulating cardiovascular risk. Objective: To investigate the individual and simultaneous association between inadequate lifestyle behaviors and risk factors for CVD in adults and older adults. Method: A cross-sectional study with 1079 users of the Health Academy Program in Brazil. Information related to inadequate diet, excessive alcohol consumption, smoking, and physical inactivity were individually and collectively investigated (0, 1, or ≥ 2 factors) in association with CVD risk factors (hypertension, hypercholesterolemia, diabetes mellitus, and obesity), considering the following two outcomes: presence of CVD risk factors and number of CVD risk factors present in the same individual (0, 1, 2, or ≥ 3 risk factors). Logistic and multinomial logistic regression analyses were used. The statistical significance adopted was 5%. Results: A higher number of inadequate lifestyle behavior was associated with greater odds of simultaneous presence of 1, 2, or ≥ 3 CVD risk factors. The simultaneous adoption of 1 and ≥ 2 inadequate lifestyle behaviors was associated with greater odds of hypercholesterolemia. Simultaneous adherence to ≥ 2 inadequate lifestyle behaviors was associated with lower odds of hypertension. Conclusion: A greater number of inadequate lifestyle behaviors was associated with higher odds of simultaneous presence of multiple CVD risk factors.

Resumo Fundamento: As doenças cardiovasculares (DCV) são frequentemente influenciadas por fatores modificáveis, principalmente pelas escolhas de estilo de vida dos indivíduos, que desempenham um papel crucial na modulação do risco cardiovascular. Objetivo: Investigar a associação individual e simultânea entre comportamentos inadequados do estilo de vida e fatores de risco para DCV em adultos e idosos. Métodos: Trata-se de um estudo transversal com 1.079 usuários do Programa Academia da Saúde no Brasil. Foram investigadas individual e coletivamente informações relacionadas a dieta inadequada, consumo excessivo de álcool, tabagismo e inatividade física (0, 1 ou ≥ 2 fatores) em associação com fatores de risco para DCV (hipertensão, hipercolesterolemia, diabetes mellitus e obesidade), considerando os dois desfechos seguintes: presença de fatores de risco para DCV e número de fatores de risco para DCV presentes no mesmo indivíduo (0, 1, 2 ou ≥ 3 fatores de risco). Foram utilizadas análises de regressão logística e multinomial. A significância estatística adotada foi de 5%. Resultados: Um maior número de comportamentos do estilo de vida inadequados foi associado a maiores chances de presença simultânea de 1, 2 ou ≥ 3 fatores de risco de DCV. A adoção simultânea de 1 e ≥ 2 comportamentos de estilo de vida inadequados foi associada a maiores chances de hipercolesterolemia. A adesão simultânea a ≥ 2 comportamentos de estilo de vida inadequados foi associada a menores chances de hipertensão. Conclusão: Um maior número de comportamentos de estilo de vida inadequados foi associado a maiores chances de presença simultânea de múltiplos fatores de risco de DCV.

Abstract Diabetes mellitus (DM) is a major cause of chronic kidney disease (CKD) and changes in lipoprotein. Literature data suggest that cholesterol associated with high-density lipoprotein (HDLc) plays a protective role against albuminuria and diabetic nephropathy. These factors are related with changes in serum apolipoproteins such Apo A-I. This work aims to evaluate the correlation of apolipoprotein A-I with renal function in diabetic outpatients. Samples were collected from 281 outpatients for analyses of glycated hemoglobin (HbA1c), serum creatinine (SCr), urea (BUN), cholesterol (TC), triglycerides (TG), HDL-cholesterol (HDLc) and estimation of glomerular filtration rate (eGFR). Urinary samples were obtained to assess urine albumin creatinine ratio (UACR). Triglyceride-glucose index (TyG) was calculated to estimate insulin resistance. The mean age was 61,5 ± 16,4 years. Most patients were female, Afro-Mestizo and over 50 years of age. Pearson's revealed negative correlation of creatinine with HDLc and Apo A-I. There was a correlation of eGFR with HbA1c, TG and HDLc. TyG presented a negative correlation with Apo A-I and HDLc. The highest quartiles of UACR presented the highest TyG and the lowest Apo A-I. In conclusion, Apo A-I indicated an association with insulin resistance and changes in renal function parameters, especially as a factor associated with the onset of albuminuria, with a better predictive potential than the HDLc.

Abstract This cross-sectional study investigated the association of SNPs rs670 (C>T) and rs693 (G>A) with parameters of lipid metabolism and endothelial activation in 167 subjects, including 86 COVID-19 outpatients and 81 healthy subjects (control group) matched for sex and age. Serum levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), non-high-density lipoprotein cholesterol (non-HDL-c), triglycerides (TG), apolipoproteins (Apo A-I and B), and vascular cell adhesion molecule-1 (VCAM-1) were determined. The SNPs were genotyped by quantitative polymerase chain reaction (qPCR). A p -value<0.05 was assumed. COVID-19 outpatients showed increases in TC (187.0±48.3 vs . 160.8±32.0 mg/dL), LDL-c (110.3±41.5 vs . 98.8±28.2 mg/dL), non-HDL-c (138.3±45.8 vs . 115.6±31.6 mg/dL), TG (139.7±80.3 vs . 84.9±35.1 mg/dL), and Apo A-I (149.5±40.0 vs . 133.3±20.9 mg/dL), along with a high frequency of hypercholesterolemia and hypertriglyceridemia. VCAM-1 levels were double those of the control (682.7±231.8 vs. 299.3±102.9 ng/mL) and a strong predictor of COVID-19 (AUC=0.946). Moreover, VCAM-1 correlated with TC (r = -0.223) and HDL-c (r = -0.225). The decrease in TG and VCAM-1 is predicted by the dominance of the T allele (rs670) and its codominance with the A (rs693) allele in COVID-19 outpatients. COVID-19 has been shown to be associated with dyslipidemias and endothelial activation, and apolipoprotein polymorphisms may influence this.

Abstract Changes in lipoprotein metabolism are among the main causes of hemodynamic impairment in renal function. COVID-19 is an multisystemic inflammatory disease, aggravating this situation. This cross-sectional study investigated the relationship of serum lipoprotein profile with inflammatory parameters and renal function in 95 COVID-19 outpatients in comparison with 173 with flu-like symptoms. Serum samples were collected for the determination of total cholesterol and fractions, apolipoproteins (Apo A-I and Apo B), urea (sUr) and creatinine (sCr). The glomerular filtration rate (eGFR) was calculated. Neutrophil/lymphocyte (NLR) and platelet/lymphocyte (PLR) ratios were calculated as inflammatory parameters derived from the blood tests. COVID-19 patients presented lower high-density lipoprotein cholesterol (HDL-c) (47.90 ± 1.543 vs. 51.40 ± 0.992) and higher PLR (190.9 ± 9.410 vs. 137.6 ± 5.534) and NLR (3.40 ± 0.22 vs. 2.80 ± 0.15). Both NLR and PLR correlated with each other (r = 0.639). Furthermore, the Apo B/Apo A-I ratio was correlated with PLR (r = 0.5818) and eGFR (r = -0.2630). COVID-19 patients classified as at high risk of developing acute myocardial infarction based on the Apo B/ Apo A-I ratio had higher values for sUr/sCr. Thus, serum apolipoproteins, PLR, and NLR could be related to renal dysfunction in COVID-19.

Resumo O objetivo foi verificar a associação entre a prática de atividade física (AF) e a percepção do ambiente em adultos de uma cidade do Sul do Brasil. Estudo transversal de base populacional com 820 adultos, residentes na cidade de Criciúma-SC. A percepção do ambiente foi avaliada pela escala Neighborhood Environmental Walkability, e a AF no domínio do lazer e transporte ativo pela versão longa do Questionário Internacional de AF. Observou-se que o bairro com lugar público para a prática de exercícios físicos e o fato de passear com o cachorro estiveram associados a maiores prevalências de atendimento às recomendações de AF moderada à vigorosa (AFMV). O fato de ter convite de amigos e/ou parentes para AF, a realização de eventos esportivos e o hábito de passear com o cachorro estiveram associados à caminhada no lazer. O acesso a locais para aquisição de frutas/legumes frescos, alimentos light/diet, ter calçadas na maioria das ruas, ter faixas de segurança e ter eventos esportivos no bairro estiveram associados a maiores prevalências de deslocamento ativo. De forma contrária, lugares para lanches ou fast-food no bairro se associaram a menor prevalência de deslocamento ativo. A percepção de variáveis do ambiente esteve associada à AFMV, à prática de caminhada e ao transporte ativo.

Abstract The article aimed to verify the association between physical activity (PA) and perceived environment among adults from a city in southern Brazil. This is a population-based cross-sectional study with 820 adults living in the city of Criciúma-SC. Perceived environment was assessed using the Neighborhood Environmental Walkability scale and PA in the leisure and transportation domains using the long version of the International PA Questionnaire. It was observed that the neighborhood with public spaces for the practice of physical exercises and dog walking was associated with higher prevalence of compliance with moderate-to-vigorous physical activity (MVPA) guidelines. The fact of having an invitation from friends and/or relatives for PA, sporting events and the habit of dog walking were associated with leisure-time walking. Access to places for the purchase of fresh fruits/ vegetables, light/diet foods, to have sidewalks in most streets, to have pedestrian crossings and sporting events in the neighborhood were associated with higher prevalence of active transportation. Conversely, places for snacks or fast food in the neighborhood were associated with lower prevalence of active transportation. The perception of environmental variables was associated with MVPA, walking and active transportation.

Resumo A força muscular é necessária para realização de atividades diárias, sendo considerada marcador de saúde global. O objetivo deste estudo foi identificar os fatores sociodemográficos e do estilo de vida correlatos à força de preensão manual (FPM) em adultos e idosos jovens. Estudo de base populacional com delineamento transversal, realizado com 705 indivíduos, de 25 a 65 anos de idade, da cidade de Florianópolis, SC, Brasil. Analisou-se a FPM por meio do instrumento de dinamometria manual. Os dados sociodemográficos e do estilo de vida foram levantados por entrevista. Utilizou-se regressão linear múltipla para a identificação das variáveis preditoras da FPM. Mulheres e indivíduos mais velhos foram os fatores associados a menores valores de FPM. Além disso, ser ativo no lazer foi associado a maiores valores de FPM. Intervenções objetivando a manutenção dos níveis de FPM nos indivíduos devem considerar o envelhecimento e aqueles inativos e insuficientemente ativos fisicamente no lazer.

Abstract Adequate muscular strength is required to perform daily activitiesand is considered a marker of overall health. The aim of this study was to identify sociodemographic and lifestyle factors associated with handgrip strength (HGS) in adults and the younger segment of the older population. A cross-sectional,population-based study was conducted with 705 individuals aged between 25 and 65 years in the city of Florianópolis, capital of the State of Santa Catarina, Brazil.HGS was assessed usinga manual hand dynamometer. Interviews were conducted with the participants to collect sociodemographic and lifestyle data.Multiple linear regressionwas performed to identify the predictors of HGS. The findings revealed that women and individuals from older age groups showed lower HGS, while being active during leisure time was associated with higher HGS.Interventions aimed at maintaining HGS levels in individuals should pay special consideration toaging and individuals who are physically inactive or insufficiently active during leisure time.

Water scarcity has direct and indirect impacts on the environment, the economy and human health. It can change the profile of morbidity and mortality of diseases, as well as having an impact on the supply of services that are essential public to the quality of life. This study aims to contextualize the occurrence of drought in Brazil, its effects on human health, as well as actions to be developed by the health sector to reduce the risk to those living in affected areas, with an emphasis on the monitoring of the quality of drinking water. This is a descriptive, qualitative study with a documental basis. The documents that were researched were related to initiatives by the Health Surveillance Secretariat of the Ministry of Health up until 2014. It is necessary to strengthen the performance capacity of the Unified Health System (SUS) in order to develop timely responses to reduce the risk to public health.

La minería del carbón en superficie provoca un intenso cambio topográfico e hidrológico en la zona por la supresión de la vegetación local, degradando el ambiente. Un problema principal presentado por el suelo rehabilitado es la perturbación física del suelo, lo que retrasa el rebrote de las especies vegetales en el área minera. El objetivo de este estudio fue evaluar la influencia de cuatro especies de gramíneas en la recuperación de las propiedades físicas del suelo en un área minera de carbón rehabilitada en Candiota, Rio Grande do Sul, sur de Brasil. Con los datos se realizó un ANDEVA y las medias de los tratamientos se compararon con la prueba de Tukey (p≤ 0.05). Los tratamientos fueron: T1-Hemarthria altissima; T2- Paspalum notatum; T3-Cynodon dactylon; T4-Urochloa brizantha; un suelo rehabilitado sin cubierta vegetal se usó como testigo. Muestras de suelo protegido se recolectaron después de 78 meses en capas de 0.00-0.10 m and 0.10-0.20 m para determinar densidad aparente, porosidad total, macroporosidad, microporosidad y capacidad de agua disponible. El proceso de rehabilitación de las zonas de minas de carbón fue lento debido al grado alto de degradación producido durante la extracción de carbón y la recuperación topográfica de la zona, lo que afecta negativamente la calidad estructural de los suelos. Las gramíneas evaluadas mostraron potencial para recuperar estas áreas, ya que se observaron mejoras en los valores de los atributos del suelo en el tiempo, especialmente en la capa de 0.00 a 0.10 m. Después de 78 meses de evaluación, U. brizantha mostró el potencial mayor para recuperar las propiedades físicas de los suelos rehabilitados de las minas.

Surface coal mining causes an intense topographic and hydrologic change in the area with suppression of local vegetation, degrading the environment. One main problem presented by the rehabilitated soil refers to physical disruption of the soil, which delays the regrowth of plant species in the mining area. The objective of this study was to evaluate the influence of four grass species in the retrieval of the rehabilitated soil's physical properties at a recovered coal mine area in Candiota, Rio Grande do Sul State, southern Brazil. With the data an ANOVA was performed and treatments means were compared using Tukey test (p ≤0.05). The treatments were: T1-Hemarthria altissima; T2-Paspalum notatum; T3-Cynodon dactylon; T4-Urochloa brizantha; a rehabilitated soil without vegetation cover was used as control. Preserved soil samples after 78 months were collected in the 0.00-0.10 m and 0.10-0.20 m layers to determine bulk density, total porosity, macroporosity, microporosity and available water capacity. The process of rehabilitation of coal mined areas was slow due to the high degree of degradation that occurs during the extraction of coal and the topographic recovery of the area, adversely affecting the structural quality of the soils. The assessed grasses showed potential to reclaim these areas, since improvements were observed in the values of the soil attributes over time, especially in the 0.00-0.10 m layer. After 78 months of evaluation, U. brizantha showed the higher potential to recover the physical properties of the compacted rehabilitated mine soils.
