Correlação de diferentes períodos de jejum com níveis séricos de cortisol, glicemia plasmática, estado clínico e equilíbrio ácido-base em cães submetidos à anestesia geral inalatória

Este estudo correlacionou os tempos de jejum sólido pré-anestésico com alterações nos níveis de glicemia plasmática, cortisol sérico, estado clínico e equilíbrio ácido-base em cães submetidos a anestesia geral inalatória. Utilizaram-se oito animais, adultos, sem raça definida, distribuídos de acordo com o período de jejum sólido: Grupo 1 (12 horas), Grupo 2 (18 horas) e Grupo 3 (24 horas). Foi acompanhado o esvaziamento do conteúdo gástrico e em seguida, todos animais foram submetidos ao mesmo procedimento anestésico. Freqüência cardíaca e respiratória, temperatura retal, tempo de reperfusão capilar, grau de hidratação e pressão arterial não-invasiva foram mensurados previamente à administração de acepromazina, 10 minutos decorridos da mesma e a cada 10 minutos durante a manutenção anestésica, incluindo-se ETCO2; valores hemogasométricos (pH, PaCO2, PaO2, HCO3, CO2 total, SatO2, déficit de base), glicêmicos e de cortisol sérico foram avaliados previamente à MPA e a cada trinta minutos durante a manutenção anestésica. No período de recuperação anestésica, novas dosagens glicêmicas e de cortisol foram realizadas. Constataram-se poucas alterações cardiocirculatórias e respiratórias durante a anestesia, não havendo interferência dos diferentes tempos de jejum. Os animais com 12 horas de jejum pré-anestésico apresentaram glicemia mais elevada do que os demais grupos, no período de recuperação anestésica. As concentrações de cortisol não foram afetadas pelo jejum. O jejum pré-anestésico sólido, independente do tempo de duração, caracterizou um quadro de discreta alcalose respiratória. Todos os animais apresentaram-se em bom estado clínico nos três grupos. Recomenda-se jejum pré-anestésico sólido de 18 horas para garantir ausência completa de conteúdo alimentar sólido no estômago.This study correlated the solid preoperative fasting periods with plasma glycemia, serum cortisol, condition clinic and acid-base balance in dogs submitted to inhalation of general anaesthesia. Eight adults, animals were distributed into three groups in accordance with solid preoperative fasting: group 1 (12 hours), group 2 (18 hours) and group 3 (24 hours). Gastric emptying was observed and following this animals were submitted to the same anesthetic procedure. Heart and respiratory rate, rectal temperature, capillary refill time, percent hydration and noninvasive arterial pressure determined before and after Acepromazine and every 10 minutes during anaesthesia, included ETCO2; values blood gas (pH, PaCO2, PaO2, HCO3, TCO2, SaO2, BE), glycemic and serum cortisol were analyzed before MPA and each 30 minutes during anaesthesia. In recovery anaesthetic, glycemia and serum cortisol were repeated. During anaesthesia there were little cardiovascular and respiratory alteration not having interference of the preoperative fasting periods. Animals with 12 hours of the preoperative fasting showed a higher rise in glycemia levels than others groups in recovery anaesthetic. Serum cortisol wasn't influenced by fasting. Solid preoperative fasting independent of the duration describe a discreet respiratory alkalosis. All animals showed good clinical condition in all three groups. Solid preoperative fasting of the 18 hours is recommended to ensure a complete absence of the solid food contents in stomach

USE OF ATHEROGENIC INDICES AS ASSESSMENT METHODS FOR CLINICAL ATHEROSCLEROTIC DISEASES

Accurate assessment of clinical atherosclerotic diseases is essential to guide effective therapeutic interventions, and atherogenic indices have emerged as valuable methods in this setting. The complexity of these pathologies demands approaches that go beyond the simple measurement of total cholesterol, requiring tools that consider the interaction between different lipoproteins and other risk factors. In this context, the use of atherogenic indices appears as a promising approach, providing a more comprehensive and refined assessment of atherosclerotic conditions. Objective: To comprehensively analyze scientific studies published in the last 10 years that investigated the use of atherogenic indices as methods of evaluating clinical atherosclerotic diseases. The review seeks to consolidate the available evidence by examining the effectiveness of these indices in early identification, risk stratification and monitoring the progress of atherosclerotic diseases. Methodology: The systematic review was conducted following the PRISMA guidelines. The PubMed, Scielo and Web of Science databases were consulted to identify relevant studies published in the last 10 years. The descriptors used were "atherogenic indices", "atherosclerotic diseases", "clinical assessment", "lipoproteins" and "cardiovascular risk factors". Inclusion criteria considered original studies that investigated the use of atherogenic indices in clinical populations, while exclusion criteria involved studies with unrepresentative samples and inadequate atherosclerotic assessment methods. Results: The results of the review highlight the diversity of available atherogenic indices and their usefulness in evaluating different aspects of atherosclerotic diseases, including prediction of cardiovascular events, risk stratification and treatment monitoring. The analysis identified indices that proved to be particularly sensitive and specific in different clinical contexts. Conclusion: In summary, the systematic review highlights the relevance of atherogenic indices as valuable tools in the assessment of clinical atherosclerotic diseases. The diversity of these indices and their ability to provide comprehensive information highlights their importance in clinical practice, contributing to a more refined and personalized approach to the management of these conditions.Accurate assessment of clinical atherosclerotic diseases is essential to guide effective therapeutic interventions, and atherogenic indices have emerged as valuable methods in this setting.

TEMAS POLÊMICOS E A ARGUMENTAÇÃO DE ESTUDANTES DO CURSO DE CIÊNCIAS BIOLÓGICAS

Analisa-se a estrutura e consistência dos argumentos de alunos do curso de Ciências Biológicas quando instigados a defender determinado ponto de vista sobre dois temas Mercado de Carbono e Experimetação Animal . Utilizando-se como referencial para análise o modelo de Toulmin, observou-se que prevaleceu Argumentos do tipo conclusão-justificativa e conclusão-dado-justificativa em ambos os debates, indicando que o método de argumentação dos alunos é derivado, principalmente, de opiniões próprias sobre o assunto ou de opiniões formadas através de aquisição de fatos aleatórios. De modo geral, os debates apresentaram uma boa expressividade e apesar dos argumentos não terem sido formuladas com base em dados científicos, há que se valorizar a importância desse tipo de atividade para o aprimoramento intelectual

Clinical Profiles and Factors Associated with Death in Adults with Dengue Admitted to Intensive Care Units, Minas Gerais, Brazil.

The purpose of our study was to describe the clinical profile of dengue-infected patients admitted to Brazilian intensive care units (ICU) and evaluate factors associated with death. A longitudinal, multicenter case series study was conducted with laboratory-confirmed dengue patients admitted to nine Brazilian ICUs situated in Minas Gerais state, southeastern Brazil from January 1, 2008, to December 31, 2013. Demographic, clinical and laboratory data; disease severity scores; and mortality were evaluated. A total of 97 patients were studied. The in-ICU and in-hospital mortality rates were 18.6% and 19.6%, respectively. Patients classified as having severe dengue according to current World Health Organization classifications showed an increased risk of death in a univariate analysis. Nonsurvivors were older, exhibited lower serum albumin concentrations and higher total leukocyte counts and serum creatinine levels. Other risk factors (vomiting, lethargy/restlessness, dyspnea/respiratory distress) were also associated with death in a univariate analysis. Multivariate analysis indicated that in-hospital mortality was significantly associated with Acute Physiology and Chronic Health Evaluation II and the Sequential Organ Failure Assessment score. The ICU and in-hospital mortality observed in this study were higher than values reported in similar studies. An increased frequency of ICU admission due to severe organ dysfunction, higher severity indices and scarcity of ICU beds may partially explain the higher mortality
