Sentidos e significados da participação democrática através da Internet: uma análise da experiência do Orçamento Participativo Digital

Este trabalho analisa três edições (2006, 2008 e 2011) do Orçamento Participativo Digital (OPD) de Belo Horizonte (MG). Objetiva deslindar os sentidos e significados da participação democrática mediada pela internet nessa experiência. Utiliza-se como método o estudo de caso único, de natureza qualitativa. Os dados foram coletados por meio de observação direta nos sítios do OPD e análise documental. Durante a fase de observação direta foram coletadas mensagens e manifestações dos cidadãos que estavam participando do processo. Tais dados foram tratados com o software Atlas TI 6.0®. Conclui-se que tanto o sentido quanto o significado democrático dessa experiência de participação mediadas pela internet são modificados ao longo das edições, indo de grandes impulsos de esperança democrática até a descrença nessa modalidade de participação digital.

Influência da internet na comunidade acadêmico-científica da área de saúde pública

OBJETIVO: Verificar a influência da internet nas atividades acadêmico-científicas da comunidade brasileira que atua na área de saúde pública. MÉTODOS: Estudo descritivo, centrado na opinião de 237 docentes vinculados aos programas de pós-graduação em saúde pública, nos níveis mestrado e doutorado, no Brasil, em 2001. Para a obtenção dos dados, optou-se por questionário auto-aplicado via web e correio postal. A análise estatística foi feita por meio de proporções, médias e desvios-padrão. RESULTADOS: O uso da internet foi apontado por 94,9%(225) da comunidade, sendo o correio eletrônico (92,0%) e a web (55,6%) os recursos mais utilizados, diariamente. A influência da internet na comunicação entre os docentes, principalmente para o desenvolvimento de pesquisas em colaboração, foi significativa (73,8 %). Declararam não utilizar a internet 5,1% dos docentes, cujas justificativas apresentadas foram a falta de motivação, falta de tempo e facilidade de conseguir de seus colegas o material de que precisam. CONCLUSÕES: Os resultados mostraram que a internet influencia o trabalho dos docentes e afeta o ciclo da comunicação científica, principalmente na rapidez de recuperação de informações. Observou-se tendência em eleger a comunicação entre os docentes como a etapa que mais mudou desde o advento da internet no mundo acadêmico-científico brasileiro.

Impacto da Internet no fluxo da comunicação científica em saúde

Com o advento da Internet e das novas tecnologias houve uma reestruturação do fluxo da comunicação científica, assim como das relações sociais no mundo. A produção de conhecimento científico também foi influenciada por essas mudanças culturais, econômicas e sociais e contribuiu para transformar os padrões de comunicação científica. O objetivo do estudo é apresentar o modelo de comunicação tradicional e sua evolução para a comunicação científica eletrônica, estimulada pelo uso de meios eletrônicos e da Internet e pelo compartilhamento em rede. Enquanto o modelo tradicional está voltado para a publicação impressa, o novo modelo propõe a publicação eletrônica e o acesso livre e irrestrito ao material publicado. Os desafios consistem na utilização de todas as potencialidades dos meios de comunicação eletrônicos para aprimorar aspectos positivos do fluxo de comunicação científica tradicional e na definição de políticas que sustentem a nova estrutura do fluxo de comunicação científica, garantindo a qualidade, preservação e disseminação da informação como bem público.

Finding Aedes aegypti in a natural breeding site in an urban zone, Sao Paulo, Southeastern Brazil

ABSTRACT This is the description of how nine Aedes aegypti larvae were found in a natural breeding site in the Pinheiros neighborhood, city of Sao Paulo, SP, Southeastern Brazil. The record was conducted in December 2014, during an entomological surveillance program of dengue virus vectors, with an active search of potential breeding sites, either artificial or natural. Finding Ae. aegypti larvae in a tree hole shows this species’ ability to use both artificial and natural environments as breeding sites and habitats, which points towards the importance of maintaining continuous surveillance on this mosquito in all kinds of water-holding containers.

Experimental paracoccidioidomycosis in hamster: transmission electron microscopy of inoculation site lesion

Interaction between Paracoccidioides brasiliensis (Pb) and inflammatory cells in hamster testis was studied sequentially by transmission electron microscopy. In early lesions (six hours after inoculation), polymorphonuclear neutrophils (PMNs) were the major and mononuclear cells and eosinophils were the minor constituents of the inflammatory cells. PMNs were later replaced by mononuclear cells. Viable Pb cells were phagocytosed or surrounded by inflammatory cells. Preserved Pb cells usually had broad host-parasite interphases, whereas dying ones had narrow interphases. The outer layer of the fungus wall was sometimes broken by PMN in some focal points, broken pieces being peeled off and phagocytosed. Small Pb cells were uninuclear, and were often related to broad interphase. Large Pb cells were multinucleated with irregularly shaped wall, and sometimes had lomasome and/or myelin like structures. Different interaction patterns of Pb with inflammatory cells may be due to functionally different host cell flow to the inoculation site or due to the age of Pb cells or both.

The hamster cheek pouch: an immunologically privileged site suitable to the study of granulomatous infections

The hamster check pouch is an invagination of oral mucosa, characterized histologically as skin-like. In this paper we describe anatomical, histological and embriological features of the pouch and coment on the pouch as an immunologically privileged site since it lacks lymphatic drainage and has few Langerhans cells. We present the review from literature and our observations after inoculation in the pouch of mycobacteriae (BCG, Mycobacterium tuberculosis and Mycobacterium leprae) and a fungus (Paracoccidioides brasiliensis). Lesions in the pouch were granulomatous but smaller and long lasting; even granulomatous, the reaction was inefficient to control the proliferation of agents compared with inoculation in other sites, except for BCG. Appearance of immunity was also delayed or absent and, when it was detected, a sharp decrease in number of agents in pouch lesions was observed. These observations make the pouch an interesting site for the study of the role of immune system in infeccious diseases and in granuloma formation.

hsp65 PCR-restriction enzyme analysis (PRA) for identification of mycobacteria in the clinical laboratory

More than 70 species of mycobacteria have been defined, and some can cause disease in humans, especially in immunocompromised patients. Species identification in most clinical laboratories is based on phenotypic characteristics and biochemical tests and final results are obtained only after two to four weeks. Quick identification methods, by reducing time for diagnosis, could expedite institution of specific treatment, increasing chances of success. PCR restriction-enzyme analysis (PRA) of the hsp65 gene was used as a rapid method for identification of 103 clinical isolates. Band patterns were interpreted by comparison with published tables and patterns available at an Internet site (http://www.hospvd.ch:8005). Concordant results of PRA and biochemical identification were obtained in 76 out of 83 isolates (91.5%). Results from 20 isolates could not be compared due to inconclusive PRA or biochemical identification. The results of this work showed that PRA could improve identification of mycobacteria in a routine setting because it is accurate, fast, and cheaper than conventional phenotypic identification.

Risky behavior regarding drug use and HIV infection: an Internet questionnaire coupled with short education texts for Portuguese speakers

Surveys of risky behavior relating to HIV/AIDS are generally made for groups at risk of infection, for which HIV/AIDS prevalence is usually expected to be higher than in the general population. Therefore, an educational homepage in Portuguese was created on the Internet to inform/ask internauts regarding knowledge and behavior. The internauts were classified as adolescents (13 to 25 years) and adults (>25 years). The number of STDs was reported as 1. 8 ± 2. 6 infections (range: 1 to 20 infections); 43% used condoms during sexual intercourse. Alcohol consumption was reported by 63% and illicit drug use by 32% (marijuana 24% and inhalants 15%). Among the adolescents, 31% did not classified alcohol as a drug. The adults more frequently reported homosexuality, anal intercourse and STDs, although the adolescents also presented high rates of risky behavior. These results show the need to reach out to internauts through better control strategies. Different types of strategies must be encouraged, in order to reach people that use this means of communication and entertainment.

Análise da informação sobre a leishmaniose visceral disponível em portais brasileiros da rede mundial de computadores: internet

Com o objetivo de analisar a adequação da informação sobre leishmaniose visceral disponível em portais brasileiros, realizou-se através de portal de busca, levantamento, seleção e análise do conteúdo das páginas eletrônicas. Foram identificadas 24 páginas com objetivos informativos, sendo oito governamentais, 10 comerciais e seis classificadas como outros. Utilizando-se um formulário, foram avaliados os conteúdos relativos à transmissão, reservatório, controle e doença, contendo tópicos considerados essenciais. Os manuais normativos do Ministério da Saúde e a literatura científica foram definidos como padrões de informação. Observou-se, em todas as páginas, elevados percentuais de ausência de informações referentes aos tópicos discriminados em cada um dos quatro blocos de conteúdos. A análise de adequação das informações, quando estas estavam presentes, mostrou 100% de adequação nas páginas governamentais e outros. Entretanto, nas páginas comerciais foram elevados os percentuais de informações incorretas ou incompletas, principalmente no bloco doença. De modo geral, o conteúdo sobre a leishmaniose visceral nas páginas eletrônicas analisadas foi considerado pouco informativo.

Predictive factors of post-discharge surgical site infections among patients from a teaching hospital

Introduction Surgical site infections (SSIs) often manifest after patients are discharged and are missed by hospital-based surveillance. Methods We conducted a case-reference study nested in a prospective cohort of patients from six surgical specialties in a teaching hospital. The factors related to SSI were compared for cases identified during the hospital stay and after discharge. Results Among 3,427 patients, 222 (6.4%) acquired an SSI. In 138 of these patients, the onset of the SSI occurred after discharge. Neurological surgery and the use of steroids were independently associated with a greater likelihood of SSI diagnosis during the hospital stay. Conclusions Our results support the idea of a specialty-based strategy for post-discharge SSI surveillance.

Surgical site infections in women and their association with clinical conditions

Introduction Surgical site infections (SSIs) can affect body tissues, cavities, or organs manipulated in surgery and constitute 14% to 16% of all infections. This study aimed to determine the incidence of SSIs in women following their discharge from a gynecology outpatient clinic, to survey different types of SSIs among women, and to verify the association of SSIs with comorbidities and clinical conditions. Methods Data were collected via analytical observation with a cross-sectional design, and the study was conducted in 1,026 women who underwent gynecological surgery in a teaching hospital in the municipality of Teresina, in the northeast Brazilian State of Piauí, from June 2011 to March 2013. Results The incidence of SSIs after discharge was 5.8% among the women in the outpatient clinic. The most prevalent surgery among the patients was hysterectomy, while the most prevalent type of SSI was superficial incisional. Comorbidities in women with SSIs included cancer, diabetes mellitus, and hypertension. Conclusions Surveillance of SSIs during the post-discharge period is critical for infection prevention and control. It is worth reflecting on the planning of surgical procedures for patients who have risk factors for the development of SSIs.

Experience with the first Internet-based course at the Faculty of Medicine, University of São Paulo

PURPOSE: The Internet expands the range and flexibility of teaching options and enhances the ability to process the ever-increasing volume of medical knowledge. The aim of this study is to describe and discuss our experience with transforming a traditional medical training course into an Internet-based course. METHOD: Sixty-nine students were enrolled for a one-month course. They answered pre- and post-course questionnaires and took a multiple-choice test to evaluate the acquired knowledge. RESULTS: Students reported that the primary value for them of this Internet-based course was that they could choose the time of their class attendance (67%). The vast majority (94%) had a private computer and were used to visiting the Internet (75%) before the course. During the course, visits were mainly during the weekends (35%) and on the last week before the test (29%). Thirty-one percent reported that they could learn by reading only from the computer screen, without the necessity of printed material. Students were satisfied with this teaching method as evidenced by the 89% who reported enjoying the experience and the 88% who said they would enroll for another course via the Internet. The most positive aspect was freedom of scheduling, and the most negative was the lack of personal contact with the teacher. From the 80 multiple-choice questions, the mean of correct answers was 45.5, and of incorrect, 34.5. CONCLUSIONS: This study demonstrates that students can successfully learn with distance learning. It provides useful information for developing other Internet-based courses. The importance of this new tool for education in a large country like Brazil seems clear.
