Investigação de danos visuais em pacientes diagnosticados com meningite criptocócica não associada à imunossupressão

A meningite criptocócica é uma severa doença infecciosa causada pelo Cryptococcus spp. que apresenta alta letalidade e deixa nos sobreviventes uma série de sequelas sensoriais, entre as quais estão as alterações visuais. O objetivo deste estudo foi descrever as perdas visuais sofridas por pacientes, sem história de imunossupressão, diagnosticados com meningite criptocócica, de forma a indicar um possível mecanismo e fatores de risco para essas sequelas visuais. O trabalho foi composto de um estudo de série de casos de pacientes com meningite criptocócica sem história de imunossupressão (n = 7 pacientes, n = 14 olhos) e um estudo transversal analítico de todos os casos de meningite criptocócica sem história de imunossupressão notificados em 14 anos num hospital de referência do Pará (n = 113 casos). No estudo de série de casos, as funções visuais de uma amostra de pacientes foi cuidadosamente analisada por meio de avaliação oftalmológica, testes psicofísicos e eletrofisiológicos. No estudo transversal analítico, foi realizada análise de dados de prontuário com enfoque nas alterações visuais. Observou-se que os pacientes estudados na série de casos apresentaram grave diminuição da acuidade visual e mesmo em pacientes sem queixa visual houve alteração na percepção de cor, na percepção de contraste de luminância em diferentes frequências espaciais e no campo visual. Os testes indicam comprometimento da retina central como principal desencadeadora de uma cascata de alterações que impedem o normal processamento da imagem no córtex visual. Sugere-se que lesões do nervo óptico não foram as únicas responsáveis pelas alterações visuais observadas. Os principais fatores de risco para as alterações visuais observados pelo estudo transversal analítico foram o tempo de doença antes do início do tratamento e a resposta imunológica do paciente.

Efeitos cardiorrespiratórios da metadona, pelas vias intramuscular e intravenosa, em cadelas submetidas à ovariossalpingo-histerectomia

Methadone is a little used opioid in veterinary practice, and there are still questions about its use. The objective of this study was to evaluate the effects of intramuscular (IM) or intravenous (IV) administration of methadone on cardiopulmonary parameters and times of extubation and recovery in female dogs submitted to ovariohysterectomy. Sixteen adult female dogs were used and premedicated with levomepromazine (0.6mg/kg, IM). After 20 minutes, propofol (5mg/kg, IV) was used for induction and anesthesia was maintained with isoflurane. After 10 minutes, methadone at 0.3mg/kg was administered intravenously in IVG and intramuscularly in IMG. The measurement of heart (HR) and respiratory rates (RR), median arterial pressure (MAP), esophagic temperature (ET) and concentration of end-tidal carbon dioxide (PE'CO2) was performed immediately before the administration of the opioid (T0), after 20 minutes (T1) and then at 10-minute intervals (T2, T3, T4 and T5). The statistical analysis used was profile (5%). HR, APM, RR, PE'CO2, BT and SpO2 did not differ significantly among times or between groups at any time. Times of extubation and recovery were higher in IVG. It is possible to conclude that IV and IM administration of methadone did not produce changes in the cardiorespiratory parameters of that specie.

Mulheres recipientes: recortes poéticos do universo feminino nas artes visuais

Mais um lançamento da Coleção Propg Digital, por meio do selo Cultura Acadêmica, Mulheres recipientes se configura como uma obra de grande sensibilidade ao realizar a interseção entre a arte e os sentimentos femininos. Resultado da dissertação de mestrado de Flavia Leme de Almeida, é necessário destacar que este livro não se restringe às generalidades de “estudos de gênero”. A proposta aqui extrapola este conceito. A autora faz uma análise múltipla: como a mulher enxerga a vida e como ela se expressa? Como o feminino aparece na arte? A partir destas questões fundamentais ela vai até os povos ancestrais, desvelar as primeiras esculturas votivas de evocação à fertilidade. Em seguida, faz um estudo de artistas mulheres contemporâneas, evidenciando como cada uma exprime suas angústias e experiências através de suas obras, destacando Frida Khalo, Louise Bourgeois, Celeida Tostes, entre outras. Por fim, Flavia Leme faz uma autoavaliação do próprio trabalho como artista, exprimindo seu processo de criação. Mulheres recipientes realiza um estudo corajoso, que não hesita em revelar para o leitor as aflições, pensamentos e projeções do feminino. Ao analisar a arte, este livro toca no íntimo de muitas mulheres e descobre experiências que não poderiam ser conhecidas de outra forma

Ivermectina e abamectina em diferentes doses e vias de aplicação contra larvas de Cochliomyia hominivorax em bolsas escrotais de bovinos recém-castrados, provenientes da região sudeste do Brasil

The preventive efficacy of ivermectin and abamectin administered in different routes (subcutaneous, intramuscular and pour-on) and doses (200 and 500mcg kg(-1)) against Cochliomyia hominivorax in the scrotal sac of cattle after castration, was evaluated. Animals from six different farms, in the state of Sao Paulo and Minas Gerais, Brazil were used. For each study, 3045 uncastrated bulls, depending on the number of groups, were selected. On day zero of the study, the procedure was carried out by the method of bloody castration and the animals were treated after this process. The efficacy of ivermectin and abamectin administered via the pour-on (500mcg kg(-1)), subcutaneous (200mcg kg(-1)) as well as the efficacy of abamectin intramuscularly (200mcg kg(-1)) were evaluated. In each experiment, one group of animals was kept as control. The animals were evaluated from the 3rd to the 14th day after castration process/treatment. The efficacy values for both active principles were <= 30% the next day 10 post-treatment (PT), and in five experiments, both ivermectin and abamectin, regardless of the route of administration, were ineffective (0.0%) on the day 10th PT. Based on the results found in this study, conducted in different properties from southeastern Brazil, both ivermectin and abamectin, when used the protocol presented, were considered ineffective in preventing scrotal myiasis in bulls, irrespective of the route of administration and dose used.

Integração do framework manakin com a plataforma dspace para múltiplas apresentações visuais de informações nos repositórios digitais

Digital repositories are currently being used by education and research institutions in Brazil as an alternative for propagating scientific and academic results, mainly to reach institutional memory and visibility. However, the way these results are presented may influence their use, affecting user-system interaction through the interface components. Thus, it is possible to state that an unique digital information environment can offer different ways of visual presentation, customizing informational and visual components for specific users communities. In this context, tools are being developed as a resource to make access and use of information easier, and to increase the usability of digital informational environments. One of these tools, Manakin, is presented in this paper, as well as its integration with the DSpace platform, in order to enable multiple visual presentations, stressing the importance of the differentiation and direction of interfaces by a single repository to the various knowledge fields. So, results and examples of repositories with multiple visual presentations are introduced, to facilitate the use of the presented tool, as well as to reinforce the importance of a differentiated visual identity by areas of knowledge in a single repository, by means of literary and exploratory analysis.

Crescimento, composição mineral e sintomas visuais de deficiência nutricional em ipeca

The objective was to evaluate the effect of the omission of macronutrient and micronutrient boron in dry matter production, the characterization of the symptoms of nutritional deficiencies and mineral composition in plants of ipeca, an experiment was conducted in greenhouse conditions by the technique the missing element and visual diagnosis. A randomized block experimental design with four repetitions and the treatments were: complete and omissions of N, P, K, Ca, Mg, S and B. The analytical results demonstrated that the production of dry matter was affected in all of the treatments with omission of nutrients and that the ipeca plants presented characteristic symptoms of nutritional deficiencies due to the omissions of N, P, K, Ca, Mg, S and B and the concentrations of the macronutrients and of the micronutrient boron in the different parts of the ipeca plant varied when a certain nutrient was omitted in the solution.

Habilidades perceptivas visuais e qualidade de escrita de escolares com dislexia

OBJECTIVE: This study aimed to characterize and compare the visual perceptual skills and writing quality of students with dyslexia, with good academic performance, and to relate the perceptual visual motor skills and the writing quality of students with dyslexia, with good academic performance. METHODS: 40 students participated in this study; 35 males and 5 females, from 8 to 11 years and 11 months, who attended from the 3rd to 5th grade level of public municipal schools of Marília-SP, divided into two groups: Group I (GI) comprised 20 students with interdisciplinar diagnoses of dyslexia, and Group II (GII) comprised 20 students with good academic performance. The Visual Perceptual Skills Test - TVPS-3 and the Disgraphy Scale were applied. RESULTS: The results obtained from this study showed that the students with dyslexia presented difficulties in visual skills concerning discrimination and memory. Besides discrimination and memory skills, it was observed inferior performance concerning the relation visual spacial skills and steady form, and inferior performance in all the visual skills, when compared to the chronological age. However, the group of students with good academic performance has also presented inferior performance concerning the relation visual spacial skills and steady form. CONCLUSIONS: The study mentions that maybe schools do not invest sufficiently in activities which envolve visual experiences necessary for the enhancement of reading and writing. Although statistically significant difference was not observed between the groups concerning disgraphy, it iwas possible to observe that a higher amount of students presented disgraphy.

Efeitos da exposição à sílica sobre a responsividade vascular e de vias aéreas de ratos

Silicosis, a common type of pneumoconiosis, is an occupational lung disease caused by inhalation of silica dust often with mining activity and thus reaches the miners. The fine and ultrafine silica particles deposited in the alveolar epithelium may lead to the development of progressive massive fibrosis. An increased reactive oxygen species (ROS) production has been proposed to explain the mechanism for induction of pulmonary fibrosis in silicosis. In this situation, alveolar macrophages are activated to phagocytes silica particles deposited in the alveoli. The activated macrophages secrete large amounts of ROS that in turn induce synthesis of fibrotic factors. In addition, the activity of antioxidant enzymes is impaired, which results in increased lipid peroxidation, as well as generating a local inflammatory process. Diffuse pulmonary fibrosis progresses with interstitial collagen deposition. Interstitial collagen overlies small pulmonary arteries and arterioles and thus it is associated with pulmonary hypertension in pulmonary fibrotic diseases. In addition, cytokines and silica particles passing through the respiratory membrane can reach the bloodstream. In this context, the increase in the generation of ROS in the circulation may lead to a reduction in the bioavailability of nitric oxide, an important endothelium-derived relaxing factor. A deficiency in the nitric oxide bioavailability can result in vascular endothelial dysfunction. Moreover, pro-inflammatory cytokines could contribute to the impairment of endothelial function. In the airways, pro-inflammatory cytokines can reduce the smooth muscle responsiveness to β- adrenergic agonists as isoproterenol. Thus, the aim of this study was to evaluate the effect of silica dust instillation in the function of the pulmonary artery, aorta and trachea of rats with acute silicosis. For this purpose, male Wistar rats were anesthetized... (Complete abstract click electronic access below)
