Alterações cardiocirculatórias no hipertireoidismo felino

The most common endocrinal disease in the cat is hyperthyroidism. The excess of the thyroidal hormones in the circulation causes a hipermetabolic state, which leads to changes in all the systems of the organism. One of the most affected being the cardiovascular. The most common changes are the ventricular hypertrophic, hypertension and thromboembolism, which also occur in primary heart disease. This revision addresses the mechanism and modifications caused by the hyperthyroidism in the cardiovascular system and its importance in the differentials diagnosis

Perfil do estilo de vida e conhecimento dos fatores de risco para doenças e agravos não transmissíveis em praticantes de atividade física em UBS de Rio Claro

Introdução: As Doenças Crônicas Não Transmissíveis (DANTS) são um grupo de enfermidades cujo processo de instalação no organismo geralmente se inicia com alterações, a prevenção dessas afecções tem sido um grande desafio para a saúde pública. As principais DANTS são: câncer, doenças do coração (angina e infarto do miocárdio), doenças do pulmão (como enfisema, bronquite e asma), doenças da circulação como acidente vascular cerebral e hipertensão arterial, doenças metabólicas como diabetes, hipercolesterolemia, a obesidade, relacionadas com condições de vida (como o estresse, depressão e ansiedade). Existem inúmeros Fatores de Risco (FR) relacionados a estes tipos de doenças, cuja remoção, ou atenuação, pode contribuir para o declínio da mortalidade.Objetivo: Associar comportamentos e conhecimentos de FR para doenças e agravos não transmissíveis de mulheres praticantes de AF através do projeto Saúde Ativa Rio Claro, este visa desenvolver e difundir práticas de intervenção cientificamente orientadas que incorporem a AF como parte integrante de um hábito de vida saudável para todas as pessoas. Metodologia: Participaram do estudo 100 mulheres, com idade média de 57,7((± 13,1), foram aplicados dois questionários, sendo o primeiro sobre conhecimento de FR para DANTS e o segundo avaliou comportamentos relacionados ao estilo de vida: nível de AF, consumo de álcool, dieta, taxa de colesterol, nível de estresse, tabagismo.Resultados e Discussão: Não houve associação entre conhecimento e comportamento, o conhecimento isoladamente não foi suficiente para promover modificações no comportamento das pessoas.

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).

Critérios diagnóstico para a cardiomiopatia arritmogênica do ventrículo direito em cães: revisão sistemática

A cardiomiopatia arritmogênica do ventrículo direito (CAVD) é uma enfermidade de caráter hereditário na qual há uma lenta e progressiva degeneração do miocárdio. As apresentações clínicas podem variar desde um animal saudável, assintomático, a episódios de síncope, fraqueza, intolerância ao exercício, tosse e aumento de volume abdominal. Visto a dificuldade diagnóstica devido às variações na forma de apresentação da doença e os diferentes achados de exames complementares, esta revisão sistemática tem como objetivo definir o melhor critério diagnóstico para a CAVD. Um total de 24 artigos foi utilizado, sendo que 18 destes relatavam o critério diagnóstico utilizado. O melhor exame complementar encontrado foi o eletrocardiograma (Holter-24 horas), no qual animais que apresentam mais de 1000 contrações ventriculares prematuras (CVPs) em 24 horas são considerados doentes

Efeitos de drogas antiplaquetárias na doença periodontal

The association between platelets, angiogenesis and progression or repair of periodontal disease has been little explored and, consequently, the results are inconclusive. The pathogenic bacteria present in the periodontal pocket release endotoxins that affect the endothelial integrity and are able to induce the production of chemical mediators derived from plasma proteins and blood clotting while altering platelet function. There is great interest in the modulation of platelet activity in vascular disorders, especially cardiovascular diseases. For this reason, antiplatelet drugs, that are commonly used in the prevention of thromboembolic diseases, such as myocardial infarction, ischemic stroke and peripheral arterial disease, have been used. Aspirin is the only non-steroidal antiinflammatory agent with antiplatelet activity. In the periodontium, instead of only reduces levels of inflammatory cytokines, also significantly affects bleeding on probing, suggesting a dose-dependent modulation of periodontitis. In contrast, clopidogrel and ticlopidine are thienopyridine drugs with no known antiinflammatory action, suggesting that this benefit is related to an antiinflammatory effect indirectly correlated to their antiplatelet activity already established. In the literature there is limited information about the effect of these drugs on periodontium and periodontal disease development. Antiplatelet drugs hypothetically can change both the pathogenesis of periodontitis and subsequent periodontal tissue repair by blocking the secretion of chemical mediators which in general are important in modulating inflammation and tissue repair.

Efeitos preventivos do exercício físico sobre as proteínas ciclooxigenase-2 (COX-2) e fator de crescimento de vasos derivado do endotélio (VEGF) no músculo cardíaco em ratos tratados com dexametasona

Dexamethasone (DEXA) is a synthetic glucocorticoid widely used in the handling of several drugs, for its proven benefits in fighting inflammation and allergies. Despite their benefits, their chronic use leads to several side effects that include changes in the body in the metabolism of carbohydrates, lipids and proteins. Moreover, being an anti-inflammatory, acts on the arachidonic acid pathway, reducing the expression of the enzyme cyclooxygenase (COX-2) and growth factor derived from the endothelium of blood vessels (VEGF) in various tissues. However, its effects on the myocardium are still uncertain. The physical training (PT), in turn, promotes effects contrary to those caused by chronic use of DEXA, however, little is known about the preventive effects of TF in the side effects of Dexa in the myocardium. Therefore, the aim of this study was to determine if the TF has the ability to prevent and/or mitigate the effects of Dexa in protein expression of COX-2 and VEGF in the myocardium. Forty animals were divided into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD), trained control (TC) and Trained treated with Dexa (TD) and submitted to a protocol of physical training on the treadmill for 70 days (1 h/day-5 days per week, 60% of physical capacity) or kept sedentary. Over the past 10 days, rats were treated with Dexa (Decadron, 0.5 mg/kg per day, ip) or saline. During training the animals were weighed weekly and during treatment daily. At the end of treatment was made to measure fasting glucose levels of animals. The rats were killed with excess anesthesia and cardiac muscle was removed, weighed, homogenized, centrifuged and stored at -20° C for analysis of protein expression of VEGF and COX-2 by Western blotting technique. Treatment with dexamethasone caused a weight loss of 18% in sedentary animals and 13% in trained as well as elevated levels of fasting glucose in sedentary (88%). The TF was unable to mitigate the loss in...

Preoperative therapy restores ventilatory parameters and reduces length of stay in patients undergoing myocardial revascularization

Introduction: The frequency of surgical procedures has increased steadily in recent decades, including the myocardial revascularization.Objectives: To demonstrate the importance of physiotherapy in the preoperative period of cardiac surgery in relation to the reduction of hospital stay, changes in lung volumes and respiratory muscle strength.Methods: We conducted a prospective study with patients undergoing myocardial revascularization, the Hospital das Clinicas da Universidade Estadual Paulista (UNESP)/Botucatu - SP. We evaluated 70 patients of both genders, aged between 40 and 75 years, subdivided into two groups: group I - 35 patients of both genders, who received a written protocol guidance, breathing exercises and respiratory muscle training in the preoperative period and group II - 35 patients of both genders, who received only orientation of the ward on the day of surgery. This study was approved by the Ethics Committee of UNESP /Botucatu - SP.Results: Maximal inspiratory pressure in third postoperative day and fifth postoperative day and significant difference between groups, being better for the intervention group. Expiratory pressure was significant in fifth postoperative day in the intervention group compared to controls. The difference of length of hospital stay in the postoperative was found between the groups with shorter hospital stay in the group receiving preoperative therapy.Conclusion: Physical therapy plays an important role in the preoperative period, so that individuals in the intervention group more readily restored the parameters evaluated before surgery, in addition, there was a decrease in the time of the postoperative hospital stay. Thus, it is thought the cost-effectiveness of a program of preoperative physiotherapy.
