ABSTRACT High Intensity Interval Training (HIIT) promotes similar adaptations and in some cases, superior to continuous aerobic training of moderate intensity, even when performed at all-out intensities. In this condition, it tends to have the greatest physiological disturbance and accumulation of metabolites compared to submaximal intensities, being one of the main factors associated with the negative response of pleasure in training. Objective: To verify the relationship between physiological and psychophysiological responses in order to repeat the training of two HIIT protocols of mesm volume load and different periods of work in trained adults of both sexes. Methods: In a randomized experiment, the sample consisted of 9 individuals aged 28±5 years, body mass 69.6±14.2 kg, height 169±0.1cm, BMI 24.1±2.3 kg/m2 and body fat percentage 20.2±7.9% practitioners of structured aerobic physical exercises for at least six months. Two different HIIT protocols were performed on an exercise bike, being (I) protocol 1:0.5, with prescribed intensity (80-90% of MAX HR), (II) protocol 1:2 with prescribed intensity (all-out) with total duration of effort of 20 minutes and interval of at least 48 hours between each session. Heart rate (HR), systemic blood pressure (SBP), subjective perception of exertion (SPE), visual analog scale (VAS), affective response (AR), fun (PACES) and intention to repeat the session were analyzed. The statistical analysis used was ANOVA with Tukey's post-hoc (p<0.05). Results: The analyses of HR, SBP, VAS, PACES and SPE showed no significant difference between the training protocols. The affective response (AR and intention to repeat) showed a decline in the protocol 1:0.5, but without significance (p>0.05). Conclusion: The data allow us to conclude that the 1:2 protocol caused greater physiological disturbances during exertion and presented greater positive affective response and intention to repeat the exercise session, variables that may contribute to adherence to regular physical exercise. Level of Evidence I; Therapeutic studies - Investigation of treatment results.

RESUMEN El entrenamiento de intervalos de alta intensidad (HIIT) promueve adaptaciones similares y, en algunos casos, superiores al entrenamiento aeróbico continuo de intensidad moderada. En esta condición, tiende a tener una mayor alteración fisiológica y acumulación de metabolitos en comparación con las intensidades submáximas, siendo uno de los principales factores asociados con la respuesta negativa del placer en el entrenamiento. Objetivo: Verificar la relación entre las respuestas fisiológicas y psicofisiológicas para repetir el entrenamiento de dos protocolos HIIT de carga del mismo volumen y diferentes períodos de trabajo en adultos entrenados de ambos sexos. Métodos: En un experimento aleatorizado, la muestra estuvo constituida por 9 individuos de 28±5 años, masa corporal 69,6±14,2 kg, altura 169±0,1cm, IMC 24,1±2,3 kg/m2 y porcentaje de grasa corporal 20,2±7,9% practicantes de ejercicios físicos aeróbicos estructurados durante al menos seis meses. Se realizaron dos protocolos HIIT diferentes en bicicleta estática, siendo protocolo 1: 0,5, con intensidad prescrita (80-90% de la FC MÁXIMA), protocolo 1: 2 con intensidad prescrita (total) con duración total del esfuerzo de 20 minutos e intervalo de al menos 48 horas entre cada sesión. Se analizaron la frecuencia cardíaca (FC), presión arterial sistémica (PAS), percepción subjetiva de esfuerzo (PSE), escala analógica visual (EVA), respuesta afectiva (FS), diversión (PACES) e intención de repetir la sesión. El análisis estadístico utilizado fue ANOVA con post-hoc de Tukey (p<0,05). Resultados: Los análisis de HR, PAS, EVA, PACES y PSE no mostraron diferencias significativas entre los protocolos de entrenamiento. La respuesta afectiva (FS e intención de repetir) mostró una disminución en el protocolo 1:0,5, pero sin significancia (p>0,05). Conclusión: Los datos permiten concluir que el protocolo 1:2 causó mayores alteraciones fisiológicas durante el esfuerzo y presentó mayor respuesta afectiva positiva e intención de repetir la sesión de ejercicio, variables que pueden contribuir para la adhesión al ejercicio físico. Nivel de Evidencia I; Estudios Terapéuticos - Investigación de los Resultados del Tratamiento.

RESUMO O Treinamento Intervalado de Alta Intensidade (HIIT) promove adaptações semelhantes e em alguns casos, superiores ao treinamento aeróbico contínuo de intensidade moderada, mesmo quando executado em intensidades all out. Nesta condição, tende a maior perturbação fisiológica e acúmulo de metabólitos comparado a intensidades submáximas, sendo um dos principais fatores associados a resposta negativa de prazer no treinamento. Objetivo: Verificar qual relação entre respostas fisiológicas e psicofisiológicas na intenção de repetir o treinamento de dois protocolos HIIT de mesmo volume load e distintos períodos de trabalho, em adultos treinados de ambos os sexos. Métodos: Em experimento randomizado, a amostra foi composta por 9 indivíduos com idade entre 28±5 anos, massa corporal 69,6±14,2 kg, estatura 169±0,1cm, IMC 24,1±2,3 kg/m2 e percentual de gordura corporal 20,2±7,9% praticantes de exercícios físicos aeróbicos estruturados por pelo menos seis meses. Realizaram dois diferentes protocolos de HIIT em bicicleta ergométrica, sendo (I) protocolo 1:0,5, com intensidade prescrita (80-90% da FCmáx), (II) protocolo 1:2 com intensidade prescrita (all-out) com duração total de esforço de 20 minutos e intervalo de pelo menos 48 horas entre cada sessão. Foram analisados frequência cardíaca (FC), pressão arterial sistêmica (PAS), percepção subjetiva de esforço (PSE), escala visual analógica (EVA), resposta afetiva (FS), divertimento (PACES) e intenção de repetir a sessão. A análise estatística usada foi ANOVA com post-hoc de Tukey (p<0,05). Resultados: As análises da FC, PAS, EVA, PACES e PSE não apresentaram diferença significativa entre os protocolos de treinamento. As respostas afetivas (FS e intenção de repetir) apresentaram maior declínio no protocolo 1:0,5, porém sem significância (p>0,05). Conclusão: Os dados permitem concluir que o protocolo 1:2 provocou maiores perturbações fisiológicas durante esforço e apresentou maior resposta afetiva positiva e intenção de repetir a sessão de exercício, variáveis que podem vir a contribuir na aderência à prática regular de exercícios físicos. Nível de Evidência I; Estudos terapêuticos – Investigação dos resultados do tratamento.

ABSTRACT Background: Critical illness is a major ongoing health care burden worldwide and is associated with high mortality rates. Sodium-glucose cotransporter-2 inhibitors have consistently shown benefits in cardiovascular and renal outcomes. The effects of sodium-glucose cotransporter-2 inhibitors in acute illness have not been properly investigated. Methods: DEFENDER is an investigator-initiated, multicenter, randomized, open-label trial designed to evaluate the efficacy and safety of dapagliflozin in 500 adult participants with acute organ dysfunction who are hospitalized in the intensive care unit. Eligible participants will be randomized 1:1 to receive dapagliflozin 10mg plus standard of care for up to 14 days or standard of care alone. The primary outcome is a hierarchical composite of hospital mortality, initiation of kidney replacement therapy, and intensive care unit length of stay, up to 28 days. Safety will be strictly monitored throughout the study. Conclusion: DEFENDER is the first study designed to investigate the use of a sodium-glucose cotransporter-2 inhibitor in general intensive care unit patients with acute organ dysfunction. It will provide relevant information on the use of drugs of this promising class in critically ill patients. ClinicalTrials.gov registry: NCT05558098

ABSTRACT Salinity is one of the main challenges in agriculture, especially in arid and semi-arid regions. Salicylic acid application may be a strategy to mitigate the harmful effects of salt stress on plant growth. Basil (Ocimum basilicum ) is a medicinal, spice, and ornamental plant grown around the world that has its growth reduced by salt stress. Therefore, the objective was to evaluate salicylic acid in mitigating the damage caused by salt stress in ‘Cinnamon’ basil. Growth was evaluated at 90 days after the start of irrigation with saline water. Salicylic acid application attenuates the harmful effects of salt stress on the number of leaves, number of inflorescences, leaf dry mass, inflorescence dry mass, root dry mass, seed mass, leaf area, leaf area ratio, specific leaf area, leaf mass ratio, root mass ratio, inflorescence mass ratio, Dickson quality index, sclerophilia index, robustness quotient and shoot root ratio. Salt stress decreased plant height, stem diameter, stem dry mass, and stem mass ratio of basil ‘Cinnamon’. Salicylic acid can be used to lessen the harmful effects of salt stress on basil ‘Cinnamon’.

Abstract The purpose of the research is to analyze socioeconomic inequality in the distribution of obesity, which is not only a disease, but also a social and economic phenomenon. In the article, the objective is to investigate the factors that make adult men and women have different probabilities of being obese in Brazil. Initially, obese individuals are identified using the Relative Fat Mass (RFM). Then, the Probit model is estimated, and Fairlie decomposition is subsequently applied. In general, the coefficients obtained are satisfactory and statistically significant. The main results indicate that women are more likely to be obese than men. The income, marital status, leisure-time physical activity, consumption of beans, alcoholic beverages and cigarettes have the greater relationship with gender inequality in obesity.

Resumo O objetivo do referente trabalho é o de analisar a obesidade, realizando uma abordagem acerca da desigualdade socioeconômica associada a essa morbidade, dado que a obesidade não é apenas uma doença, constituindo-se também como um fenômeno social e econômico. O artigo investiga os fatores que fazem homens e mulheres adultos terem probabilidades distintas de serem obesos no Brasil. Inicialmente, são identificados os indivíduos obesos, a partir da medida de Massa Gorda Relativa (RFM). Em seguida, estima-se o modelo Probit, com a posterior aplicação da decomposição de Fairlie. Os coeficientes obtidos, em geral, exibem os sinais esperados e são estatisticamente significativos. Os principais resultados apontam que as mulheres possuem maiores chances de serem obesas, com a renda, estado civil, atividade física no lazer, consumo de feijão, bebida alcoólica e cigarro sendo variáveis que apresentam maior relação com a desigualdade de gênero na obesidade.

Abstract The objective of this study was to present information on the impacts resulting from Covid-19 on the artisanal coalho cheese production chain about: access to information; socioeconomic; income and government support; healthcare. The interviews were conducted using the Google Forms tool, with milk and artisanal coalho cheese producers in Rio Grande do Norte, Brazil. The producers obtained a lot of information transmitted on television (66%); the majority to adhere to health protocols. There was instability in the production, with an initial need to reduce production resulting from prohibitive measures to trade. The level of demand with regard to the consumer market increased with the quality of milk and cheeses. An allegation of lack of support from the government to maintain the activity was also verified in 78.7% of the interviewees, but 83% had resorted to emergency aid. Therefore, it can be concluded that the challenges imposed by the pandemic are not just sanitary. The study confirmed the need to restructure public services and policies. These results can provide compelling evidence about the rural context in the country.

ABSTRACT. Emulsifiers in animal diets are an interesting and effective strategy for nutritionists to improve the digestion of dietary lipids and, consequently, provide better performance. This study aimed to evaluate the effect of the supplementation of diets with emulsifier based on mono- and diglycerides (120 g t-1 of feed) associated with different energy levels (2,775; 2,725; 2,675 and 2,625 kcal of metabolizable energy kg-1 of feed) on performance and egg quality of Hisex Brown laying hens. The laying hens were distributed in 50 experimental plots with eight birds each. A completely randomized design with five treatments and ten replicates/treatments was used. The treatments in this study were: control diet (C) with 2,775 kcal of metabolizable energy (ME) kg-1 of feed; C + E: diet C supplemented with an emulsifier (E) at 120 g t-1 of feed; diet C with reduction of 50 kcal ME and supplemented with E (NC50 + E); diet C with reduction of 100 kcal ME and supplemented with E (NC100 + E); and diet C with reduction of 150 kcal ME and supplemented with E (NC150 + E). All diets had the same inclusion level of degummed soybean oil (2%). There was no influence of the treatments on the performance and quality of the eggs (p >0.05). The current study has shown that diets supplemented with emulsifiers based on mono- and diglycerides (120 g t-1) allows reducing the metabolizable energy level up to 150 kcal kg-1 of feed, without impairment on performance and egg quality of Hisex Brown laying hens.

Abstract The demands of high-quality zucchini fruits by the consumer market make studies regarding the improvement of cultivation systems, such as plant nutrition and salinity tolerance. Considering the demands of the consumer market for the high quality of zucchini fruits, it is necessary studies regarding the improvement of production systems for this improvement, such as nutrition and salinity tolerance to plant. Thus, this study aimed to evaluate the zucchini fruits quality characteristics, grown in soilless, under N:K ratios, and levels of electrical conductivity of the nutrient solution. The experiment was conducted in a protected environment in pots with 8.2 dm3 of volumetric capacity filled with commercial substrate. The trial design adopted was randomized blocks, with three replicates, in a 5x3 factorial scheme, with five levels of electrical conductivity (1.0; 2.0; 3.0; 4.0; and 5.0 dS m-1) and three N:K ratios (2:1; 1:1; and 1:2), both in the nutrient solution. The application of the nutrient solution was by fertigation through drip irrigation. Throughout the experiment, variables related to fruit quality and total plant biomass production were analyzed. The increase of the electrical conductivity in the nutrient solution provided an increase in the values of fruits organoleptic properties. Regarding the nutrient solution N:K ratios, the 1:2 ratio provided larger fruits and a higher percentage of water.

ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p<0.001], had a lower SAPS 3 Score [45 (42-52) versus 49 (43-57); p<0.001], lower SOFA Score on intensive care unit admission [3 (1-6) versus 4 (2-6); p=0.018], lower Charlson Comorbidity Index [0 (0-1) versus 1 (0-2); p<0.001], and were less frequently frail (10.4% versus 18.1%; p<0.001). The second wave group used more noninvasive ventilation (81.3% versus 53.4%; p<0.001) and high-flow nasal cannula (63.2% versus 23.0%; p<0.001) during their intensive care unit stay. The intensive care unit (11.3% versus 10.5%; p=0.696) and in-hospital mortality (12.3% versus 12.1%; p=0.998) rates did not differ between both waves. Conclusion In the first and second waves, patients with severe COVID-19 exhibited similar mortality rates and need for invasive organ support, despite the second wave group being younger and less severely ill at the time of intensive care unit admission.

ABSTRACT Objectives: This study aimed to evaluate the functional results of the treatment protocol for the treatment of transolecranon fracture-dislocation, by surgical reduction and osteosynthesis with plate and screws, in patients attended at a referral hospital for orthopedic trauma, with a minimum follow-up period of six months. Methods: Twenty-five individuals treated surgically from January 2014 to November 2018 were selected for a primary observational longitudinal study using questionnaires to assess upper limb and elbow function (DASH and MEPS), quality of life (SF-12), pain (visual analog scale - VAS), and radiographic evaluation in anteroposterior and lateral views of the elbow. Results: Fifteen patients were male, and the mean age was 46.8 years. All participants had their fractures consolidated, with no radiolgraphic signs of implant failure, or degenerative arthritis. Mean range of motion was reduced relative to the contralateral limb: 102.6º for flexion-extension and 132.8º for pronation-supination. The mean MEPS and DASH scores were 89.6 and 16.5 respectively. There was no residual pain in 84% of the cases according to the VAS. Conclusion: The surgical treatment proposed for transolecranon fracture-dislocations showed satisfactory results according to MEPS, DASH scores and quality of life measures. Evidence Level IV; Retrospective observational study.

RESUMO Objetivo: Avaliar os resultados funcionais do protocolo de tratamento da fratura-luxação transolecraniana, por redução cirúrgica e osteossíntese com placa e parafusos, nos pacientes atendidos em hospital de referência para trauma ortopédico, com seguimento mínimo de seis meses. Métodos: vinte e cinco indivíduos tratados cirurgicamente de janeiro de 2014 a novembro de 2018 foram selecionados para um estudo longitudinal observacional primário, utilizando questionários para avaliar a função do membro superior e cotovelo (DASH e MEPS), qualidade de vida (SF-12), dor (visual escala analógica - EVA), e avaliação radiográfica nas incidências anteroposterior e perfil do cotovelo. Resultados: Quinze pacientes eram do sexo masculino e a média de idade foi de 46,8 anos. Todos os participantes tiveram suas fraturas consolidadas, sem sinais radiográficos de falha do implante ou artrite degenerativa. A amplitude média do movimento foi reduzida em relação ao membro contralateral: 102,6º para flexo-extensão e 132,8º para pronossupinação. Os escores médios de MEPS e DASH foram 89,6 e 16,5, respectivamente. Não houve dor residual em 84% dos casos de acordo com a EAV. Conclusão: O tratamento cirúrgico proposto para a fratura-luxação transolecraniana apresentou resultados satisfatórios de acordo com MEPS, escores DASH e medidas de qualidade de vida. Nível de evidência IV; Estudo observacional retrospectivo.

ABSTRACT The Covid-19 pandemic provoked a reevaluation of teacher-student dynamics, prompting the adoption of innovative approaches to ensure student engagement, participation, academic performance, and retention. To effectively address the emerging challenges in this context, mixed methods research was conducted, anchored by the Design Science Research approach, where artifacts were developed, evaluated, and systematized in a collaborative serious game, MASTER-PM. The findings demonstrated the game’s positive impact on teamwork learning outcomes, and valuable student feedback facilitated iterative enhancements to the game and its support artifacts. This paper describes the MASTER-PM application in an undergraduate administration course at a Brazilian university and evaluates its viability and usefulness in project management education.

ABSTRACT This study highlights some of the aspects of Brazilian economic development in the 21st century, relating its productive structure to the economic complexity of exports. It seeks to understand how the profile of Brazilian exports reflects its internal productive structure based on the way in which Brazil has reinserted itself into international trade in a scenario of greater trade openness since the 1990s based on two complementary and integrated approaches: the economic complexity of exports, aiming to identify the competitiveness of exported products that are produced in the national territory; and the linkage indexes of the input-output matrix, which aim to identify the linkage effects as a way of understanding the organization of its internal productive structure, highlighting the classification proposed by Kupfer (1998). It is identified that the internal productive structure of the Brazilian economy tends toward the expansion of chains of more competitive products in international trade even if less complex. The growing relevance of the chaining effects of less complex products, allied to the increase in their competitiveness and participation in the export basket, despite contributing to GDP growth in some periods, shows the structural limitations of national economic development.

RESUMO Este artigo destaca alguns aspectos do desenvolvimento econômico brasileiro no século XXI, relacionando a estrutura produtiva com a complexidade econômica das exportações. Procura compreender como o perfil das exportações brasileiras reflete a estrutura produtiva interna, a partir da forma como o Brasil se reinseriu no comércio internacional desde os anos 1990, em um cenário de maior abertura comercial. Foram utilizadas duas formas de abordagem complementares e integradas: a complexidade econômica das exportações, com o objetivo de identificar a competitividade dos produtos exportados que são produzidos em território nacional; e os índices de ligação da matriz insumo-produto, a fim de identificar os efeitos de encadeamento como uma forma de compreender a organização da estrutura produtiva interna, destacando-se a classificação proposta por Kupfer (1998). Verifica-se que a estrutura produtiva interna da economia brasileira tende para a ampliação de encadeamentos de produtos mais competitivos no comércio internacional, ainda que menos complexos. A crescente relevância dos efeitos de encadeamento de produtos menos complexos, aliada ao aumento de sua competitividade e participação na pauta de exportações, ainda que contribua para o crescimento do PIB em alguns períodos, revela limitações estruturais do desenvolvimento econômico nacional.

Abstract Medication-related osteonecrosis of the jaw (MRONJ) is characterized by bone exposure for more than eight weeks in patients who have used or been treated with antiresorptive or antiangiogenic drugs, without a history of radiation therapy or metastatic diseases in the jaws. Obesity is associated with changes in periodontal tissues and oral microbiota that are linked to bone alterations. This study aimed to analyze the influence of obesity on the development of bisphosphonate-induced osteonecrosis. The experiment randomly and simply divided 24 male Wistar rats (Rattus norvegicus) into four groups: healthy, with osteonecrosis, obese, and obese with osteonecrosis (n=6 per group). Osteonecrosis was induced through weekly intraperitoneal injection for eight weeks at a dose of 250 µg/kg of zoledronic acid in a 4 mg/5 mL solution, combined with trauma (exodontia). Obesity was induced through a high glycaemic index diet. Each group was qualitatively and quantitatively evaluated regarding the development of models and pathological anatomy of the lesions. The results were expressed in mean percentage and standard deviation and statistically analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc test, with a significance level of 5% (p<0.05) to establish differences found between the groups. Animals in the osteonecrosis group and the obese with osteonecrosis group presented larger necrosis areas (averages: 172.83±18,19 µm2 and 290.33±15,77 µm2, respectively) (p<0,0001). Bone sequestration, hepatic steatosis, and increased adipocyte size were observed in the obese group (average: 97.75±1.91 µm2) and in the obese with osteonecrosis group (average: 98.41±1.56 µm2), indicating greater tissue damage in these groups (p<0,0001). All parameters analyzed (through histological, morphometric, and murinometric analyses) increased for the obese and obese with osteonecrosis groups, suggesting a possible influence of obesity on the results. However, further studies are needed to confirm the role of obesity in the possible exacerbation of osteonecrosis and understand the underlying mechanisms.

Abstract The geographical distribution of sand flies in Brazil has been the subject of some studies, yet there is no information about the phlebotomine fauna in João Pessoa, State of Paraíba, Brazil. The aim of this work is to evaluate the occurrence and distribution of sand flies in the Atlantic forest fragments and to evaluate a possible dispersion in 06 nearby districts. Light traps were used during three consecutive nights, supplemented by an aspirator during the dry period and rainy season. A total of 222 sand flies were found, 143 (130 males and 13 females) in the Atlantic forest, and 79 in urban areas. During the entire dry season, three species of phlebotomine sand flies were recorded in 11 forest fragments, Lutzomyia longipalpis, Lu. migonei and Lu. whitmani. During the rainy season, only Lu. longipalpis was found. This was the only species identified in the studied neighborhoods during both seasons. The differences in diversity of sand flies encountered between natural habitats and urban areas may thus be correlated mostly with adaptations to particular habitats and availability of food. One species (Lu. longipalpis) appears to be rapidly adapting to urban areas because of deforestation.
