Tipo de conhecimento sobre inclusão produzido pelas pesquisas

As pesquisas brasileiras sobre produção de conhecimento no campo da Educação Especial iniciaram-se há mais de 15 anos. No presente objetivou-se analisar o tipo de conhecimento produzido nessa área frente à metodologia empregada nas dissertações e teses financiadas pelo Programa de Apoio a Educação Especial. Os trabalhos de conclusão de curso analisados referiam-se àqueles projetos aprovados pelo Proesp no âmbito do Estado de São Paulo. O período de análise ficou compreendido entre 2004 e 2008. Vinte e sete estudos foram localizados. A análise dos estudos foi realizada por meio de cinco categorias: 1) pesquisas que apresentaram generalização e aplicação imediata dos resultados; 2) pesquisas que apresentaram resultados imediatos para um grupo específico de participantes; 3) pesquisas descritivas com achados inovadores; 4) pesquisas de intervenção com achados inovadores; 5) pesquisas descritivas que corroboraram outras pesquisas. Foi possível concluir que os estudos avançaram nos conhecimentos sobre a inclusão e que o uso de metodologias pouco utilizadas no campo da educação serviu de subsídio para obter os resultados.

Estudo sorológico de infecções experimentais por Trypanosoma evansi, em cobaias

Comparamos os métodos de Imunofluorescência Indireta (IFI), Imunodifusão Radial Dupla e Aglutinação, para a pesquisa de anticorpos em soros, na tripanossomíase experimental por Trypanosoma evansi, em cobaias. Foram obtidas 20 amostras de soro correspondentes às 4 primeiras semanas de infecção. A IFI foi positiva em apenas 6 animais, com títulos variando de 1:4 a 1:16. Os títulos mais altos foram observados na 3ª semana pós-infecção. Anticorpos aglutinantes foram observados a partir da 1ª semana pós-infecção e, após a 2ª semana, todos os animais apresentaram reação de aglutinação positiva, com títulos variando de 1:8.000 a 1:250.000. O tratamento dos soros com 2-Mercapto-etanol inibiu a reação de aglutinação, sugerindo ser IgM a principal classe dos anticorpos presentes no soro dos animais infectados. Não se constatou a presença de anticorpos precipitantes durante todo o curso da infecção.

O poder e as injustiças nas pesquisas em seres humanos

Após considerações gerais sobre a ética na pesquisa envolvendo seres humanos, focaliza-se a possibilidade de ocorrências de injustiças, sob a égide de diversas formas de poder. Exemplificam-se situações concretas. Enfatiza-se a análise das possíveis injustiças à luz da Bioética, com destaque para multi e transdisciplinaridade. O autor se posiciona quanto às características atuais da Bioética, cuja ótica levou à elaboração das Diretrizes éticas para a pesquisa envolvendo seres humanos, no Brasil (Resolução 196/96 e complementares do Conselho Nacional de Saúde). Descreve-se a sistemática das atividades do Grupo Executivo de Trabalho - GET, designado pelo Conselho Nacional de Saúde (órgão de controle social na área da saúde), para elaborar as Diretrizes. É dado destaque à participação dos diversos segmentos da sociedade, evidenciando multi e transdiciplinaridade, sob a coordenação do GET, do qual o autor foi Presidente. Comentam-se os principais tópicos das Diretrizes brasileiras, enfocando-se a sua relação com o tema de poder e injustiça. Salienta-se o papel dos Comitês de Ética em Pesquisa - CEP e da Comissão Nacional de Ética em Pesquisa - CONEP.

Determinantes da evolução do peso e altura em crianças de 3 meses a 6 anos assistidas em creche: Análise por modelo linear não hierarquizado em ensaio quase-experimental

Objective. To assess factors determining growth in a group of children between 3 months and 6 years old enrolled in a public municipal (i.e., government-supported, not private) day-care center, in comparison to a group of children with similar characteristics but who were not enrolled in the center. Methods. A quasi-experimental study was designed to observe 444 children aged 3 to 72 months from a low-income neighborhood in the city of Sorocaba, in the state of São Paulo, Brazil. Two groups were studied: 164 children enrolled in a local municipal day-care center (intervention group) and 280 not receiving care at the center (nonintervention, comparison group) but instead being cared for at home. Both groups were seen four times over a period of 16 months. At each observation session, the children's weight and height were measured. Information was also collected on the mother's sociodemographic characteristics and the illnesses she had suffered as well as the child's weight and other health characteristics at birth, the child's illnesses in the 15 days before each observation, and any hospitalizations. Results. The children in both groups were from low-income families, with 65% of the families having an average monthly income below US$ 100; 80% of the mothers had received 8 years of schooling or less. Multivariate linear regression analysis showed that at the first observation (just before enrollment in the day-care center), birth weight was the only factor that explained the nutritional differences between the two groups. Subsequent analyses showed that being in day care was the factor that best explained the differences between the groups, especially in terms of the adequacy of weight for age, after controlling for birthweight, sex, age at the beginning of the study, and illnesses in the 15 days before an observation session. The nutritional impact of the intervention was significant as early as 3 months after being enrolled in day care. Conclusions. The nutritional benefits of the care provided at the center outweighed the negative effects sometimes seen in such centers, such as the greater morbidity that children in day-care centers often experience in comparison to children receiving care at home.

Lesões intestinais decorrentes de isquemia e reperfusão: Fisiopatologia e modelos experimentais

The intestinal ischemia is unusual in vascular surgery emergency. Its main causes are embolisms and arterial thrombosis. In addition to severe ischemia, reperfusion of the ischemic tissues can lead to several complications that may worsen the ischemic lesion and produce a life threatening situation caused by systemic alterations. Intestinal tissue injuries due to ischemia and reperfusion have been demonstrated in clinical and experimental studies, in which pathophysiology and adequate treatment were also studied. The great variety of experimental models used and results achieved reflect the need for an intestinal ischemia and reperfusion experimental model that is simple, reproducible and consistent, in order to search for treatments that can reduce the damage caused by this situation. In this review, the main pathophysiologic aspects and the most used experimental models will be reviewed. Copyright © 2005 by Sociedade Brasileira de Angiologia e Cirurgia Vascular.

Efeitos da fenilbutazona na cicatrização de feridas cutâneas experimentais em equinos

The purpose of this study was to investigate phenylbutazone effects on second intention wound healing, and to compare the healing process between the thoracic and lumbar areas. Ten horses were submitted to circular full-thickness wound produced on both sides of the thoracic and lumbar areas. Animals were gathered into two experimental groups, one receiving daily IV injections of phenylbutazone (4,4mg/kg) and the other (control group) distillated water for five days. All wounds were daily treated with local Dakin's solution. The wound contraction rates were determined by serial measurements each 72 hours. At the 6th and 15th post surgical days, biopsies were performed for histological analysis. Thoracic and lumbar wound contraction was decreased in the phenylbutazone group. The time to complete healing was significantly greater in phenylbutazone group (49 days) than in control group (37 days). There was no significant difference between thoracic and lumbar area in the same group. Gross and histopathology analysis showed the inhibitory effect of phenylbutazone on the second-intention wound healing when compared to the control group.

Estudo de perfil de dissolução dos medicamentos de referência, genérico e similar contendo cefalexina na forma farmacêutica cápsula

With recent advances in technology and research into drug delivery, the modernization of tests and greater emphasis on the predictability of therapeutic effect by means of in vitro tests, the dissolution test and the study of dissolution profiles are gaining more and more importance. Though introduced initially as a way of characterizing the release profile of poorly soluble drugs, dissolution tests are currently part of pharmacopoeial monographs on almost all the oral solid pharmaceutical forms. The objective of this study was to determine the dissolution profile (percent drug dissolved versus time) of the pioneer brand, generic and similar pharmaceutical capsules containing 500mg cephalexin. Three pharmaceutical brands (reference, generic and similar) were subjected to the dissolution test and in vitro dissolution profiles were recorded. From the results of the dissolution test, it was concluded that the samples met the acceptance criterion, as no difference was observed in the percentage of the drug dissolved in a standard time. The dissolution profile indicated that this medicine, in this pharmaceutical form, dissolves readily (85% of the drug dissolved in 15 minutes) and the curves showed great similarity, suggesting that the 3 brands are pharmaceutically equivalent.
