Muller, Luis Antnio;Rabelo, Eneida Rejane;Moraes, Maria Antonieta;Azzolin, Karina;
Revista Latino-Americana de Enfermagem , 2008, DOI: 10.1590/S0104-11692008000100009
Abstract: objective: to identify factors that delay the onset of thrombolysis in patients with acute myocardial infarction (ami). methods: a cohort study was carried out with 146 patients, each diagnosed with ami and subjected to thrombolytic therapy. the data was extracted from medical records between january 2002 and december 2004. results: the average age of the studied population was 57.5 ± 9 years, 64.4% were male. the average time between the onset of pain and arrival at the hospital was 254.7 ± 126.6 minutes, 28.1% used an ambulance for the trip to the hospital, the door-to-electrocardiogram time averaged 19.4 ± 7.3 minutes and the door-to-needle time was 51.1 ± 14.9 minutes. there was no significant difference between the time of arrival to the hospital and the method of transportation used (p= 0.81), and those seen by cardiologists and during the nightshift had a reduction in the door-to-needle time, respectively (p=0.014) and (p=0.034). conclusions: study results show that the delay in the search for medical service, and the long time taken from door-to-electrocardiogram and to reach the ami diagnosis were the factors involved in the delay of thrombolytic treatment.
Radial Applanation Tonometry as an Adjuvant Tool in the Noninvasive Arterial Stiffness and Blood Pressure Assessment  [PDF]
Lucas José Sá da Fonseca, Marco Antnio Mota-Gomes, Luíza A. Rabelo
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.45030
Abstract: Since antiquity, the human arterial pulse represents an important parameter in the clinical assessment. Besides being routinely assessed in the medical practice, such pulse is not observed in its completeness yet, once many of the data obtained through it cannot be evaluated using conventional methods. Taking into account such methods, the measurement of arterial blood pressure using sphygmomanometry, although broadly widespread in the assessment and follow-up of patients who require accompaniment of their cardiovascular status, is not able to properly guide about parameters related to the central hemodynamic status, the latter most strongly associated with cardiovascular risk. Such incapability is due to the centrifugal augmentation of the pressures taken at different points of the arterial bed, based on the properties of the closed arterial system through which the blood flow travels. In this context, methodologies capable of assessing central parameters estimated using the pulse wave analysis, such as applanation tonometry, represent a promising adjuvant for evaluating patients with cardiovascular diseases, by providing detailed information concerning hemodynamic parameters otherwise inaccessible. In this scenario, the present review focuses on the applanation tonometry and its assessment on the radial artery, highlighting the importance of this method in the cardiovascular assessment, as well as its relevance in the clinical practice, when determining parameters peripherally obtained capable of estimating the central hemodynamic status.

Abstract: Adoption of corporative governance practices allegedly leads to greater transparency of company policies, strategies and actions thereby increasing asset values especially shares. For this reason an analysis was made to identify behavior of abnormal returns during adoption of the Bovespa Differentiated Levels of Corporative Governance by ten companies between 2001 and 2003 and to ascertain the impact on stockholders. Event Study methodology was used and abnormal returns were calculated by the Model of Returns Adjusted to Market, in logarithmic form. The conclusion was that adoption of the Bovespa Corporative Governance practices by ten companies did not generally bring about abnormal returns or create wealth for stockholders. A ado o de práticas de governan a corporativa supostamente leva a uma maior transparência nas políticas, estratégias e a es empresariais, que resulta na valoriza o dos ativos das empresas que as adotam, principalmente das suas a es no mercado. Baseado nessa premissa, este artigo analisou o comportamento dos retornos anormais em períodos próximos à ades o de 10 empresas aos Níveis Diferenciados de Governan a Corporativa da Bovespa, ocorrida entre 2001 e 2003, visando avaliar o seu impacto sobre o retorno dos acionistas, isto é, se criou valor para os seus acionistas. Utilizou-se a metodologia de Estudo de Evento e, para o cálculo dos retornos anormais, o Modelo de Retornos Ajustados ao Mercado na forma logarítmica. Conclui-se que a ades o das empresas analisadas n o proporcionou, de maneira geral, retornos anormais para seus acionistas, ou seja, n o resultou na cria o de riqueza para estes últimos.
MORFOLOGICAL AND HISTOCHEMICAL OBSERVATIONS ON THE SALIVARY GLANDS OF THE ALLIGATOR Caiman latirostris OBSERVA ES MORFOLóGICAS E HISTOQUíMICAS SOBRE AS GL NDULAS SALIVARES DO JACARé Caiman latirostris (Crocodilia Reptilia)

Abstract: Using histological and histochemical methods for glicoconjugates, the present work on the salivary glands of the alligator Caiman latirostris (Crocodilia Reptilia), was developed. On the bases of the results obtained, the authors believe that those glands are not well developed, appearing as unicellular structures goblet-like cells, in the stratified squamous epithelium of the oral cavity. Scattered glands alveolus without excretory tubules which extend directly with the epitelium were also present. By means of histochemical methods for glicoconjugates, it was possible to detect the glicoprotein and the sialic acid in the glandular formation of these animals. Empregando-se métodos histológicos e histoquímicos para glicoconjugados, desenvolveu-se um trabalho sobre glandulas salivares do jacaré Caiman latirostris. Com base nos resultados obtidos, constatou-se que estas glandulas s o pouco desenvolvidas, aparecendo como estruturas unicelulares, semelhantes às células caliciformes, incluídas no epitélio estratificado pavimentoso da cavidade oral. Observou-se, ainda, a presen a de esparsos alvéolos glandulares desprovidos de ductos excretores que continuam diretamente com o epitélio. Por meio de métodos histoquímicos para glicoconjugados, foi possível a detec o de glicoproteína e de ácido siálico nas forma es glandulares desses animais.

Abstract: the authors propose the treatment of aortic aneurysms by using an intraluminal graft. a new device which transforms any kind of graft of different sizes and diameters into an intraluminal one is described. this new device just needs an extra-vascular circunferential ligature and does not require any fixation suture. the use of the rigid, sulcated delrin (r) ring simplifies the technique shortening the duration of the surgery, reducing surgical bleeding and dispensing the use of profound hypothermia and platelet transfusion. between may 1989 and january 1993, 22 patients were submited to aneurysmectomy of the aorta using this technique. twelve patients exhibited acute aortic dissection (type i and ii debakey), one debakey type iii acute aortic dissection, two presented descending aortic aneurysm, two cases were of thoraco-abdominal aortic aneurysm and five aneurysms of abdominal aorta. three patients died in the imediate post-operative period from cerebrovascular accident, mesenteric thrombosis and pulmonary infection. the survivors have been followed up as outpatients.

Abstract: during the last decade, cardiovascular surgery has experienced an extraordinary impetus through the development of the diagnostic methods, techniques of myocardic and cerebral protection, suture and extracorporeal circulation techniques, which provided greater experience to surgeons and permitted them to question the medical therapy recommendations for acute type b aortic dissection. the surgical treatment seeks to reduce the high mortality rate of this pathology in a short and long run. the elephant trunk technique, discribed by borst and adapted by palma and buffolo, for the treatment of acute type b aortic dissection offers good results as well as a simple technique that does not require handling the diseased and friable aortic tissue during the procedure. between june 31, 1992 and february 20, 1995, 7 patients were operated on using this technique; 1 female patient and 6 male patients. there were 2 (28.5%) deaths but neither of them was related to the surgical technique. in this paper, we present a modification in the elephant trunk technique, using the intraluminal ring, developed at our hospital.

Abstract: Realizaram-se testes físicos de tra o e alongamento até ruptura em dez tiras com 5 a 6 mm de largura, do exemplar in natura e dos respectivos exemplares conservados em glicerina a 98% e glutaraldeído a 4% por 30 dias para a avalia o da influência de ambos os conservantes sobre o tecido biológico, com vistas ao aproveitamento em cirurgias reparadoras. Paralelamente, avaliou-se a atividade anti-séptica dos conservantes, por meio de exames microbiológicos de fragmentos colhidos do material in natura e dos respectivos exemplares submetidos à conserva o. Os testes físicos mostraram que sete amostras conservadas em glutaraldeído a 4% suportaram maior for a de tens o, quando comparadas com os respectivos exemplares in natura e conservados em glicerina a 98%. Duas amostras apresentaram comportamento semelhante quanto ao ponto de rompimento, para ambos os conservantes. Apenas em uma amostra verificou-se que o material in natura apresentou um ponto de rompimento superior às amostras conservadas. Observou-se crescimento bacteriano apenas em quatro amostras no material in natura. Os mesmos exames realizados em amostras conservadas n o revelaram nenhum crescimento. Conclui-se que tanto a glicerina a 98%quanto o glutaraldeído a 4% demonstraram ser eficientes na conserva o do material, bem como na atividade bactericida durante o período de 30 dias.

Abstract: This study has two main objectives: on one hand, the evaluation of food items related to the food training courses in order to know which ones require better explanations from trainers and a further development and refinement by food handlers. It is also a goal of this work to appreciate the level of general knowledge of food handlers before receive any training session and then see if there was some improvement after the course. On the other hand, identifying potential social and personal factors of food handlers that influence on the results of the evaluation. To this end, two tests were performed (one before the training and at the end) and evaluated the results per modules. In general, knowledge levels both initially and after taking the course proved to be satisfactory. Personal and social factors determined better or worse scores on the basis of these.
