Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

Abstract Tityus serrulatus scorpion is responsible for a significant number of envenomings in Brazil, ranging from mild to severe, and in some cases, leading to fatalities. While supportive care is the primary treatment modality, moderate and severe cases require antivenom administration despite potential limitations and adverse effects. The remarkable proliferation of T. serrulatus scorpions, attributed to their biology and asexual reproduction, contributes to a high incidence of envenomation. T. serrulatus scorpion venom predominantly consists of short proteins acting as neurotoxins (α and β), that primarily target ion channels. Nevertheless, high molecular weight compounds, including metalloproteases, serine proteases, phospholipases, and hyaluronidases, are also present in the venom. These compounds play a crucial role in envenomation, influencing the severity of symptoms and the spread of venom. This review endeavors to comprehensively understand the T. serrulatus scorpion venom by elucidating the primary high molecular weight compounds and exploring their potential contributions to envenomation. Understanding these compounds' mechanisms of action can aid in developing more effective treatments and prevention strategies, ultimately mitigating the impact of scorpion envenomation on public health in Brazil.

ABSTRACT BACKGROUND AND OBJECTIVES: The mechanisms underlying nociplastic pain, such as fibromyalgia (FM), are not fully understood, however, it is believed that altered sensory processing and pain modulation play prominent roles in the maintenance of nociplastic pain. The hypothesis is that changes in the primary somesthetic cortex (S1) contribute to the generalized pain character of FM. The objective of this study was to evaluate the involvement of the primary somesthetic cortex in humans with fibromyalgia, as well as to investigate possible associations between S1 changes and clinical signs and symptoms of FM. CONTENTS: For this integrative review, the following databases were used: Pubmed and Web of Science, including observational studies carried out in humans with FM. In total, 541 studies were identified and four were included. The majority of studies are case-control studies, published between 2016 and 2022. In total, data from 161 individuals were included in this review. It was identified that there are morphological changes, hyperactivation and increased functional connectivity between S1 and periaqueductal gray matter and between S1 and anterior cingulate cortex. CONCLUSION: Patients with FM present morphological changes and hyperactivation in S1, as well as increased functional connectivity between S1 and periaqueductal gray matter and S1 and limbic system. Furthermore, different bilateral somatotropic subregions (legs, chest, fingers, hands, face and back) showed reduced functional connectivity in patients with FM. These regions are often presented as “tender points” in FM.

RESUMO JUSTIFICATIVA E OBJETIVOS: Os mecanismos subjacentes à dor nociplástica, como a fibromialgia (FM), não são totalmente compreendidos, contudo acredita-se que o processamento sensorial e a modulação da dor alterados desempenham papéis proeminentes para a manutenção da dor nociplástica. Com a hipótese de que alterações no córtex somestésico primário (S1) contribuam para o caráter de dor generalizada da FM, o objetivo deste estudo foi avaliar o envolvimento do córtex somestésico primário em humanos com FM, bem como investigar possíveis associações entre alterações de S1 com sinais e sintomas clínicos da FM. CONTEÚDO: Para esta revisão integrativa, foram utilizadas as seguintes bases de dados: Pubmed e Web of Science, incluindo estudos observacionais realizados em humanos com FM. No total, 541 estudos foram identificados e quatro foram incluídos. A maioria dos estudos são do tipo caso-controle, publicados entre 2016 e 2022. Ao todo, dados de 161 indivíduos foram incluídos. Foi identificado que há alterações morfológicas, hiperativação e aumento da conectividade funcional entre S1 e substância cinzenta periaquedutal e entre S1 e córtex cingulado anterior. CONCLUSÃO: Pacientes com FM apresentam alterações morfológicas e hiperativação em S1, bem como aumento da conectividade funcional entre S1 e substância cinzenta periaquedutal e S1 e sistema límbico. Ademais, diferentes sub-regiões somatotrópicas bilaterais (pernas, tórax, dedos, mãos, face e costas) apresentaram redução da conectividade funcional em pacientes com FM. Essas regiões são frequentemente apresentadas como “tender points” na FM.

Abstract Studies investigating the effects of different modalities of exercises on the immune system are scarce. Therefore, the aim of this study was to compare the effects of eight weeks of resistance and aerobic training on the proliferation of T and B lymphocytes from mice. Eighteen male C56BL6/J mice were divided into groups (n=6), sedentary, aerobic, and resistance training. After 8 weeks, animals were euthanized, and their splenocytes were labeled and cultured with and without stimulation. Lymphocyte proliferation (CD4+, CD8+ and CD21/CD35+) was evaluated by flow cytometry. The mice subjected to resistance exercise exhibited greater proliferation for total, CD8+ and B lymphocytes (p<0.05), but not CD4+ cells (p>0.05), compared with their sedentary counterparts. We found significant correlations between maximum load and total, CD8+ and B lymphocytes proliferation rates (p<0.05). In conclusion, our results showed that resistance training promoted an improvement in the immune response associated with CD8+ and B lymphocytes.

Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites.

Abstract: Creation, adjustments and adoption of tests and tools that help in the prediction of seed storability have been highly demanded. Therefore, this work aimed to analyze the efficiency of different artificial aging times in predicting the performance of soybean seeds after storage, using the GGE biplot method. Seeds of six genotypes were subjected to storage, under refrigerated and non-refrigerated conditions, and artificial aging, being artificially aged for periods of 0, 48, 96 and 144 hours. Seeds freshly harvested and after natural and artificial aging were subjected to germination and vigor tests. The experiments were analyzed separately, using means test, regression analysis and model identity test, and together, using the GGE biplot method. Artificial aging at a temperature of 41 °C for 96 hours has the potential to be used to predict the performance of soybean seeds after eight months of storage. The GGE biplot is a method that can be used as a tool to analyze the relationships between aging environments and visualize the ranking of genotypes regarding the performance of seeds subjected to natural and artificial aging.

Resumo: Tem sido altamente requerida a elaboração, ajustes e adoção de testes e ferramentas que auxiliem na predição da armazenabilidade de sementes. Diante disso, este trabalho teve por objetivo analisar a eficiência de diferentes tempos de envelhecimento artificial na predição do desempenho das sementes de soja após o armazenamento, utilizando-se o método GGE biplot. Sementes de seis genótipos foram submetidas ao armazenamento, sob condição refrigerada e não refrigerada, e envelhecimento artificial, sendo envelhecidas artificialmente pelos períodos de 0, 48, 96 e 144 horas. As sementes recém-colhidas e após o envelhecimento natural e artificial foram submetidas a testes de germinação e vigor. Os experimentos foram analisados separadamente, por meio de teste de médias, análise de regressão e teste de identidade de modelos, e em conjunto, utilizando-se o método GGE biplot. O envelhecimento artificial, à temperatura de 41 °C por 96 horas apresenta potencial para ser utilizado na predição do desempenho de sementes de soja após oito meses de armazenamento. O GGE biplot é um método que pode ser utilizado como ferramenta para analisar as relações entre os ambientes de envelhecimento e visualizar o ranqueamento dos genótipos quanto ao desempenho das sementes submetidas ao envelhecimento natural e artificial.

Abstract This study analyzed the construction process of the chosen name and related aspects among transgender individuals from a medium-sized municipality in southern Brazil. Qualitative data from a descriptive and exploratory mixed-method study was used. Self-declared trans people aged 18 or over were included. Three focus groups were conducted with ten participants. These individuals, aged between 19 and 52 years, have a documented chosen name, but half have not yet changed their civil records. The content analysis technique produced two categories: “construction of the chosen name as an instrument for validating the transgender identity” and “impacts of the construction of the chosen name on self-acceptance and on family and social relationships.” The results reinforce the importance of respecting the name as a way of contributing to the gender affirmation of transgender individuals. The name was linked to the experiences, individuality and values of these individuals. Its proper use, much more than respect for legislation, meant respect for the different possibilities of human existence. It is expected that the results presented can be used as a tool for recognizing the issues and nuances that permeate the construction of the chosen name and contribute to identity validation.

Resumo O trabalho analisou o processo de construção do nome social e aspectos relacionados em pessoas trans de um município de porte médio do Sul do Brasil. Foram utilizados dados qualitativos de um estudo de método misto descritivo e exploratório. Incluíram-se pessoas autodeclaradas trans com 18 anos ou mais. Foram conduzidos três grupos focais com dez participantes. Estes, com idade variando entre 19 e 52 anos, apresentam nome social documentado, porém metade ainda não fez a alteração nos registros civis. A técnica da análise de conteúdo produziu duas categorias: “construção do nome social como instrumento de validação da identidade trans” e “impactos da construção do nome social na autoaceitação e nas relações familiares e sociais”. Os resultados reforçam a importância do respeito ao nome como forma de contribuição para a afirmação de gênero de sujeitos trans. O nome esteve atrelado às suas vivências, individualidades e valores. Seu uso adequado, muito mais do que o cumprimento de uma legislação, significou respeito às possibilidades diversas da existência humana. Espera-se que os resultados apresentados possam ser utilizados como ferramenta de reconhecimento acerca das questões e nuances que permeiam a construção do nome social, bem como contribuam para a validação identitária.

Abstract Trust in institutions and democracy. The cases of young Spanish and Latin Americans This article examines data from the Jóvenes en Iberoamérica 2021 survey, coordinated by the SM Foundation of Spain, which interviewed 13,500 young people aged between 15 and 29 from Argentina, Brazil, Chile, Colombia, Ecuador, Spain, Mexico, Peru and the Dominican Republic between March 2019 and April 2020. The study aimed to measure the perception of these young people regarding the determinants of trust in relation to political and social institutions that constitute, in contemporary societies, the fundamental bases for the exercise of democratic life. The data shows, in general, a low level of trust in institutions among young people in these countries.

Abstract This ecological study examined time series, from 2002 to 20121, of age-adjusted coefficients of cervical cancer mortality, in Brazil, in women aged 20 years or more, by race. The information sources were Brazil’s mortality information system (Sistema de Informação sobre Mortalidade - SIM) and the official bureau of statistics (Instituto Brasileiro de Geografia e Estatística - IBGE). Annual changes in age-adjusted mortality rates were calculated using the Prais-Winsten linear regression method. Black women die more and the rate is decreasing less. Racial inequality has increased over the years. In 2002, there were 0.08 more deaths per 100,000 women in the black population than among white women; in 2021, the number was one death. Health policymaking should consider racial differences in the implementation of strategies and goals.

Resumo O objetivo desse artigo é analisar séries temporais da mortalidade por câncer de colo do útero segundo raça/cor no Brasil de 2002 a 2021. Estudo ecológico de séries temporais com dados do Sistema de Informação sobre Mortalidade e informações populacionais do IBGE. Variações anuais das taxas de mortalidade ajustadas por idade de mulheres de 20 anos ou mais foram estimadas pelo modelo de regressão linear simples com correção de Prais-Winsten. Foram registrados 133.429 óbitos por câncer de colo de útero, destes, 51,2% foram de mulheres negras. As mulheres negras morrem mais e têm menor queda do coeficiente. Houve aumento da desigualdade racial ao longo dos anos. Em 2002, ocorriam 0,08 óbitos/100 mil mulheres a mais na população negra comparada com a população branca; em 2021 esse número é de aproximadamente 1 óbito. Para a elaboração de políticas de saúde da mulher devem ser consideradas as diferenças raciais na implementação de estratégias e metas.

ABSTRACT: The present study described the prevalence and factors associated with the seropositivity for anti-Brucella spp. antibodies in working equids in the semiarid regionofnortheastern Brazil. Blood samples were collected from 322 equids (76 horses, 155 mules and 91 donkeys). The Rose Bengal plate test (RBPT) was used as a screening method. Samples that were reactive in the RBPT were tested for confirmation using 2-mercaptoethanol (2-ME) and the standard tube agglutination test (STAT). Overall, 7.1% (23/322) of the samples were positive according to the RBPT. After confirmatory tests, the prevalence of brucellosis was found to be 6.5% (21/322). Among these cases, 33.3% (7/21) were horses, 42.8% (9/21) were mules and 23.9% (5/21) were donkeys. In the multivariate analysis, age over 10 years was considered to be a factor associated with the seropositivity (OR: 17.17; 95% CI: 2.582-164.7, P = 0.006) for anti-Brucella spp. antibodies. The significant prevalence of anti-Brucella spp. antibodies found in working equids and the wide distribution of positive animals demonstrates a worrying epidemiological situation regarding brucellosis in the study region. Age over 10 years was a risk factor associated with the seropositivity for anti-Brucella spp. antibodies in animals.

RESUMO: O objetivo do presente estudo foi descrever a prevalência e os fatores associados à infecção por Brucellaspp. em equídeos de trabalho na região semiárida do Nordeste do Brasil. Amostras de sangue foram coletadas de 322 equídeos (76 equinos, 155 muares e 91 asininos). O teste de placa Rosa Bengala (RBPT) foi usado como método de triagem. As amostras que foram reativas no RBPT foram enviadas para confirmação usando 2-mercaptoetanol (2-ME) e o teste padrão de aglutinação em tubo (STAT). Ao todo, 7,1% (23/322) das amostras foram positivas segundo o RBPT. Após testes confirmatórios, a prevalência de brucelose foi de 6,5% (21/322). Destes casos, 33,3% (7/21) foram equinos, 42,8% (9/21) muares e 23,9% (5/21) asininos. Na análise multivariada, idade acima de 10 anos foi considerada fator associado à infecção (OR: 17,17; 95% CI: 2,582-164,7, P = 0.006) por Brucellas pp. A prevalência significativa de anticorpos anti-Brucella spp. encontrados em equídeos de trabalho e a ampla distribuição de animais positivos demonstra uma situação epidemiológica preocupante em relação à brucelose na região de estudo. A idade superior a 10 anos foi um fator de risco associado à infecção em animais.

Abstract This work aims the assessment of the dynamic structural response of reinforced concrete floors subjected to rhythmic human activities, based on the use of biodynamic models, in order to consider the people-structure interaction effect. Initially, an experimental modal analysis on the investigated floor , with dimensions of 16m x 35m, was performed, in order to identify and assess the global dynamic behaviour of the structure. In sequence, a finite element model was developed and calibrated through experimental results. After that, based on forced vibration analyses, the floor dynamic response was determined (displacements and accelerations). It is concluded that the biodynamic systems modelling induced significant attenuations on the structural response when compared to those calculated based on the use of traditional “only force” models.

Resumo Este trabalho tem como objetivo a avaliação da resposta dinâmica de pisos de concreto armado submetidos a atividades humanas rítmicas, com base no uso de sistemas biodinâmicos, a fim de analisar o efeito de interação pessoa-estrutura. Inicialmente, realizou-se uma análise modal experimental sobre o piso investigado, com dimensões de 16m x 35m, visando identificar e avaliar o comportamento dinâmico global da estrutura. Em seguida, um modelo de elementos finitos foi desenvolvido e calibrado com base nos resultados experimentais. Posteriormente, a partir das análises de vibração forçada, a resposta dinâmica do piso foi determinada (deslocamentos e acelerações). Conclui-se que a modelagem dos sistemas biodinâmicos induziu atenuações significativas sobre a resposta estrutural quando comparadas àquelas calculadas via utilização de modelos tradicionais de força-rítmica.

ABSTRACT Second-generation glyphosate-tolerant maize (Roundup Ready 2, RR2) is characterised by the expression of the cp4epsps gene. Despite some studies suggesting possible undesirable effects from the application of glyphosate in RR2 maize, other reports have demonstrated glyphosate selectivity for RR2 plants, with minor damage symptoms, if any, and with no negative effects on the chlorophyll indices. The aim of this study was to evaluate the effect of different types of glyphosate management, formulations and rates of application on chlorophyll indices and the agronomic performance of an RR2 maize genotype expressing the cp4epsps gene. Five experiments were conducted in a full factorial design (2 x 5 x 5) to evaluate two types of management, two formulations and five rates of glyphosate. Damage symptoms, chlorophyll indices and variables related to agronomic performance (plant height, stem diameter, yield and 100-grain weight) were evaluated. Similar crop responses were found for each of the glyphosate formulations (potassium salt and isopropylamine salt) and types of management (single application and sequential application) under test, indicating that the use of glyphosate-based commercial products affords flexibility in terms of formulation and frequency of application. Glyphosate formulated as potassium salt or isopropylamine salt and applied to RR2 maize either in a single application (full rate) or in two sequential applications (each at half rate) has a similar effect and may therefore be used without distinction. However, it is important to consider the rate of application since high rates of glyphosate (especially greater than 1,440 g ae ha-1) may affect the development and production of RR2 maize.

ABSTRACT This work aimed at investigating the viability of near infrared spectrometry (NIR), associated with chemometric methods, in order to identify differences at the levels of vigor of naturally and artificially aged soybean seeds. Seeds of six soybean genotypes were analyzed when freshly harvested, after natural aging in storage for eight months, and after artificial aging at the temperature of 41 °C for 96 hours. The seed moisture content, germination potential and vigor were evaluated. Also, there were measured the content of protein, oil and of the fatty acids: palmitic, stearic, oleic, linoleic and linolenic. The NIR spectra were obtained from the freeze-dried and grinded seeds. The natural and artificial aging of the seeds promote deterioration at distinct levels, reflecting in differences in seed vigor. The regions of the electromagnetic spectrum between wavelengths of 1000-1200 nm, 1350-1450 nm, 1800-1900 nm and 2300-2400 nm are important to distinguish the levels of quality of the soybean seeds. The contents of oil and protein have a relationship with the physiological quality of the seeds. Also, the most relevant wavelengths for the classification of seed vigor present a relationship with these compounds. NIR spectroscopy, in combination with chemometric methods, presents potential to be used in the classification of soybean seeds regarding their physiological quality.

ABSTRACT: The objective of the present study was to evaluate clinical, cardiorespiratory, and Doppler echocardiographic changes in rabbits sedated with midazolam and morphine combined with or without dexmedetomidine. This study was a blinded, randomized, controlled experiment that included 16 adult male New Zealand rabbits weighing 3.1 ± 0.3 kg. The animals were sedated using one of the following protocols: 1 mg/kg midazolam and 2 mg/kg morphine (MIDA, n = 8), or 25 mg/kg dexmedetomidine, 2 mg/kg morphine and 1 mg/kg midazolam (DEX, n = 8). Sedation latency, duration of the sedation and recovery period, sedation scores, heart rate (HR), respiratory rate (f), peripheral oxygen saturation (SpO2), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), and recta temperature were recorded, and Doppler echocardiography was performed. Latency periods were 7.3±1.6 min in the DEX group and 10.9 ± 5.0 min in the MIDA group (P = 0.112). Sedation duration was 122.4±14 min in the DEX group and 71.2 ± 32 min in the MIDA group (P = 0.005), whereas recovery time was 35.7±17.7 min in the DEX group and 32.5 ± 25.3 min in the MIDA group (P = 0.743). The sedation scores for the DEX group were significantly higher than those for the MIDA group throughout the monitoring period. Reductions in HR, SAP, MAP, and DAP values were observed in both groups relative to baseline values, and were significantly lower in the DEX group compared to the MIDA group. Minimal Doppler echocardiographic changes were observed. Dexmedetomidine used in combination with midazolam and morphine incremented the quality and duration of sedation in rabbits. Both protocols elicited cardiorespiratory changes that were well-tolerated, with minimal changes in myocardial function.

RESUMO: O objetivo do presente estudo foi avaliar alterações clínicas, cardiorrespiratórias e ecodopplercardiográficas, bem como o nível de sedação em coelhos sedados com midazolam e morfina combinadas, ou não, com dexmedetomidina. O design do estudo foi experimental controlado randomizado cego, com 16 coelhos adultos machos Nova Zelândia, pesando 3,1 ± 0,3 Kg. Os animais foram sedados aleatoriamente com um dos seguintes tratamentos: MIDA (n = 8): 1 mg/kg de midazolam e 2 mg/kg de morfina; DEX (n = 8) 25 mcg/kg de dexmedetomidina, 2 mg/kg de morfina e 1 mg/kg de midazolam; Latência, sedação e períodos de recuperação, escores de sedação, FC, f, SpO2, PAS, PAM, PAD, ToC, foram mensurados e ecoDopplercardiografia foi realizada. Os períodos de latência foram 7.3 ± 1.6 minutos no grupo DEX e 10.9 ± 5.0 minutos no grupo MIDA (P = 0,112). A duração da sedação foi de 122.4 ± 14 minutos no grupo DEX e 71.2 ± 32 minutos no grupo MIDA (P = 0,005). Os tempos totais de recuperação foram de 35.7 ± 17.7 minutos no grupo DEX e 32.5 ± 25.3 minutos no MIDA (P = 0,743). Os escores de sedação obtidos do grupo DEX foram estatisticamente superiores aos do grupo MIDA durante todas as observações (de 5 a 40 minutos). A redução dos valores de FC, PAS, PAM e PAD foi observada em ambos os grupos, em relação ao momento baseline, e foram significativamente menores no grupo DEX quando comparado ao MIDA. Alterações ecodopplercardiográficas mínimas foram observadas ambos os grupos. A adição de dexmedetomidina à associação midazolam/morfina aumentou o nível, a qualidade e a duração do protocolo sedativo. Ambos os protocolos causaram alterações cardiorrespiratórias bem toleradas em animais normais e com mínimas alterações na função miocárdica.
