    Communities inhabiting biogeographic transition zones are shifting in composition as a result of progressive warming and heatwaves. In the marine environment, corals are expanding onto higher latitude reefs historically dominated by temperate kelp forests, initiating a shift towards warm affinity coral-dominated states.publishedVersio

    Does the Evaluation of Coagulation Factors Contribute to Etiological Diagnosis of Pleural Effusions?

    OBJECTIVE: The aim of this study was to identify the participation of the coagulation system in the differential diagnosis of pleural effusions. INTRODUCTION: Imbalance between immunologic and metabolic factors triggers a sequence of events resulting in pleural reactions and accumulation of fluid. The coagulation system, which is fundamental for the maintenance of homeostasis, contributes to the inflammatory process responsible for pleural effusions, and participates in cellular proliferation and migration as well as in the synthesis of inflammatory mediators. METHODS: We evaluated the laboratory profile of coagulation and fibrinolysis in 54 pleural fluids (15 transudates and 39 exudates). RESULTS: The coagulation system acts according to the pathophysiologic mechanisms involved in the development of pleural effusions. In inflammatory effusions (exudates), there is activation of coagulation with increased levels of fragment 1+2 and thrombin-antithrombin complex in addition to reduction of fibrinogen levels due to fibrinolysis and fibrin tissue incorporation. As a consequence, there is activation of the fibrinolytic system with increased levels of fibrin degradation products, including the D-dimer. These changes are not sufficient for differentiation of different subgroups of exudates. In transudates, these events were observed to a lesser degree. CONCLUSION: The coagulation system plays an important role in the development of pleural diseases. Coagulation tests show differences between transudates and exudates but not among exudate subgroups. Understanding the physiopathological mechanisms of pleural disorders may help to define new diagnostic and therapeutic approaches

    The aim of this study was to develop a technological tool in the form of a mobile application that provides functionalities for the easy calculation of reproductive and productive efficiency indices. This tool aims to assist breeders, technicians, and students of agricultural sciences in decision-making for the challenges faced in cattle production systems. The application was developed using the Android Studio development environment and the Dart programming language framework known as Flutter. The application's graphical interface follows Google guidelines in the Material Design documentation. The tool will provide a practical way to calculate recognized indexes of productive efficiency of cow-calf systems and provide information such as goals and management tips to help users achieve better results. The impact of the developed product is its use as an information platform, facilitating decision-making in the area of beef cattle production and as an efficient means of disseminating technologies generated by research institutions and popularizing science. Thus, the application is an accessible and comprehensible tool, providing a means of evaluating the technologies and management practices adopted in beef cattle farms

    Avaliação da prevalĂȘncia da doença de Chagas aguda em crianças e prĂ©-adolescentes de 0 a 14 anos no perĂ­odo 2010 a 2018, no Brasil / Evaluation of the prevalence of acute Chagas disease in children and pre-adolescents aged 0 to 14 years from 2010 to 2018, in Brazil

    Identificar a prevalĂȘncia da doença de Chagas aguda em crianças e prĂ©-adolescentes no Brasil, no perĂ­odo de 2010 a 2018. Estudo epidemiolĂłgico, transversal, descritivo sobre a doença de Chagas aguda, a partir de informaçÔes disponibilizadas pelo MinistĂ©rio da SaĂșde no banco de dados DATASUS TABNET, verificando a prevalĂȘncia por idade de 0 a 14 anos pelo nĂșmero de notificaçÔes em todo Brasil, analisando zonas de extrema pobreza, alĂ©m do predomĂ­nio de menor e maior idade dentro da faixa etĂĄria estabelecida. Evidenciou-se um nĂșmero crescente de casos ao longo dos anos, passando de 136 casos em 2010 para 361 em 2018, sendo que ao relacionar com a zona de extrema pobreza houve uma incidĂȘncia de 637 notificaçÔes no perĂ­odo. Devido Ă  situação socioeconĂŽmica de regiĂ”es perifĂ©ricas do paĂ­s, hĂĄ uma grande dificuldade no controle da doença em crianças, mesmo apesar de medidas que incentivem o aumento da triagem no prĂ©-natal, a prevenção da enfermidade aguda congĂȘnita, o controle quĂ­mico vetorial e a melhoria de inĂșmeras moradias em zona de risco

    Introdução: A obesidade Ă© uma doença de etiologia multifatorial, se apresentando como uma das mais prevalentes sĂ­ndromes do mundo. Tal condição pode ser definida como excesso de gordura corporal, mensurada pelo IMC. A molĂ©stia pode apresentar diversas repercussĂ”es negativas no bem-estar do indivĂ­duo, como doenças metabĂłlicas e cardiovasculares, alĂ©m de prejuĂ­zos sociais e psicolĂłgicos. Objetivo: O presente estudo teve como objetivo realizar uma revisĂŁo narrativa acerca das principais consequĂȘncias da obesidade a longo prazo. MĂ©todo: Trata-se de uma revisĂŁo narrativa com buscas na Scielo, Pubmed e Lilacs, no perĂ­odo de 2012 a 2022, utilizando os termos chave: “obesidade”, “consequĂȘncias”, “evolução mĂ©dica”, “obesity” e “consequences”. Resultados: Foram selecionados 10 artigos no total, sendo 4 na Scielo, 4 no Pubmed e 2 na Lilacs, por corresponderem ao objetivo do trabalho. DiscussĂŁo: A principal consequĂȘncia da obesidade se apresenta nos distĂșrbios metabĂłlicos, com destaque para a Diabetes tipo 2, devido ao aumento da inflamação e, portanto, da resistĂȘncia Ă  insulina. Outros impactos repercutem na osteoartrite, diversos tipos de cĂąncer, doença renal crĂŽnica e condiçÔes que podem levar a pessoa acometida a Ăłbito. IndivĂ­duos obesos estĂŁo vulnerĂĄveis a questĂ”es sociais, como isolamento e discriminação e podem, portanto, desenvolver doenças psicolĂłgicas. ConclusĂŁo: Conclui-se que a obesidade deve ser tratada de forma multidisciplinar, sugerindo novos estudos relacionados aos prejuĂ­zos laborais sofridos pelos trabalhadores obesos
