A Afetividade na Relação Pedagógica e Aprendizagem na Pré-Escola

O presente trabalho propõe uma reflexão sobre o Estágio da Prática de Ensino Supervisionada (PES) realizada no contexto do Curso de Mestrado em Ensino de 1º e 2º Ciclos do Ensino Básico do Instituto Politécnico da Guarda (IPG) e aprofunda o tema “A importância da afetividade na relação escolar e suas implicações na aprendizagem na pré-escola”. As aulas do Estágio ocorreram na UEB Luzenir Mata Roma no ano de 2015. Em relação ao tema aprofundado na pesquisa referente à Educação Infantil, as observações e aplicações de atividades se deram na UEB Olívio Castelo Branco, escola da Rede Pública Municipal de São Luís. Os principais objetivos da realização deste estudo consistiram em compreender de que maneiras a afetividade pode influenciar o desenvolvimento cognitivo e social das crianças da Educação Infantil. Perceber de que forma os educadores conduzem as atividades docentes propiciando às crianças momentos lúdicos de aprendizagem e convívio harmonioso com os colegas. A metodologia utilizada na realização do trabalho foi a pesquisa qualitativo-descritiva na qual a escola tornou-se espaço laboratório de observação e aplicação do instrumento de produção e coleta de dados. Como resultados obtidos com o estudo tivemos a sensibilização do olhar dos educadores sobre o fenômeno da afetividade no desenvolvimento das crianças da pré escola, uma melhor qualidade nas relações interpessoais na escola entre crianças e entre crianças e educadores. Divide-se o trabalho em três capítulos ao longo dos quais se comtempla a importância da pesquisa de campo, observação e da prática no estágio supervisionada, descrevendo todas as etapas vivenciadas em campo, bem como os fatores do contexto social que influenciam diretamente e indiretamente a aprendizagem dos alunos envolvidos no processo de ensino da instituição escolar selecionada. A pesquisa mostrou que a escola possui um papel crucial no desenvolvimento do ser humano, principalmente na primeira infância, logo a educação escolar deve fortalecer os laços afetivos, tendo em vista o desenvolvimento da criança como pessoa. Para tal, é de suma importância identificar os fatores emocionais que influenciam o processo de aprendizagem, ou dificultam o relacionamento no ambiente escolar

Exantema após vacinação do sarampo: análise laboratorial de casos notificados em São Paulo

OBJECTIVE: The clinical differential diagnosis of rash due to viral infections is often difficult, and misdiagnosis is not rare, especially after the introduction of measles and rubella vaccination. A study to determine the etiological diagnosis of exanthema was carried out in a group of children after measles vaccination. METHODS: Sera collected from children with rash who received measles vaccine were reported in 1999. They were analyzed for IgM antibodies against measles virus, rubella virus, human parvovirus B19 (HPV B19) using ELISA commercial techniques, and human herpes virus 6 (HHV 6) using immunofluorescence commercial technique. Viremia for each of those viruses was tested using a polimerase chain reaction (PCR). RESULTS: A total of 17 cases of children with exanthema after measles immunization were reported in 1999. The children, aged 9 to 12 months (median 10 months), had a blood sample taken for laboratory analysis. The time between vaccination and the first rash signs varied from 1 to 60 days. The serological results of those 17 children suspected of measles or rubella infection showed the following etiological diagnosis: 17.6% (3 in 17) HPV B19 infection; 76.5% (13 in 17) HHV 6 infection; 5.9% (1 in 17) rash due to measles vaccine. CONCLUSIONS: The study data indicate that infection due to HPV B19 or HHV 6 can be misdiagnosed as exanthema due to measles vaccination. Therefore, it is important to better characterize the etiology of rash in order to avoid attributing it incorrectly to measles vaccine.OBJETIVO: O diagnóstico diferencial de doenças exantemáticas causadas por vírus é geralmente difícil, e equívocos não são raros, especialmente depois da introdução da vacina contra o sarampo e a rubéola. Um estudo laboratorial foi conduzido com o objetivo de estabelecer o diagnóstico etiológico de casos de exantema em crianças que receberam a vacina contra o sarampo. MÉTODOS: Soros de casos de exantema em crianças que receberam vacina contra o sarampo, em 1999, foram analisados para anticorpos IgM contra os vírus do sarampo, da rubéola e do parvovírus humano B19 (HPV B19), por técnicas comerciais de Elisa, e o herpes vírus humano tipo 6 (HHV 6), por técnica comercial de imunofluorecência. A viremia para cada um desses vírus foi testada pela reação em cadeia da polimerase (PCR). RESULTADOS: Foram notificados, em 1999, 17 casos de crianças com exantema pós-vacinal. A idade das crianças era de nove a 12 meses (mediana, dez meses). Uma amostra de sangue colhida para investigação laboratorial foi obtida para cada criança. O tempo decorrido entre a aplicação da vacina e o aparecimento do exantema variou de um a 60 dias. Os resultados da sorologia das 17 crianças sugeriram o seguinte diagnóstico etiológico para o exantema: 17,6% (três em 17) infecção pelo HPV B19; 76,5% (13 em 17) infecção pelo HHV 6; 5,9% (um em 17) exantema originado pela vacina do sarampo. CONCLUSÃO: Os resultados indicaram que a infecção pelo HPV B19 ou pelo HHV 6 pode ser diagnosticada como sarampo de origem vacinal. Portanto, é fundamental incluir esses vírus no diagnóstico laboratorial para corretamente apontar a etiologia das doenças exantemáticas, evitando, assim, atribuir à vacina do sarampo efeito colateral

Five-year review of an international clinical research-training program

The exponential increase in clinical research has profoundly changed medical sciences. Evidence that has accumulated in the past three decades from clinical trials has led to the proposal that clinical care should not be based solely on clinical expertise and patient values, and should integrate robust data from systematic research. As a consequence, clinical research has become more complex and methods have become more rigorous, and evidence is usually not easily translated into clinical practice. Therefore, the instruction of clinical research methods for scientists and clinicians must adapt to this new reality. To address this challenge, a global distance-learning clinical research-training program was developed, based on collaborative learning, the pedagogical goal of which was to develop critical thinking skills in clinical research. We describe and analyze the challenges and possible solutions of this course after 5 years of experience (2008-2012) with this program. Through evaluation by students and faculty, we identified and reviewed the following challenges of our program: 1) student engagement and motivation, 2) impact of heterogeneous audience on learning, 3) learning in large groups, 4) enhancing group learning, 5) enhancing social presence, 6) dropouts, 7) quality control, and 8) course management. We discuss these issues and potential alternatives with regard to our research and background

A model for adapting evidence-based behavioral interventions to a new culture: HIV prevention for psychiatric patients in Rio de Janeiro, Brazil

As in other countries worldwide, adults with severe mental illness in Brazil have elevated rates of HIV infection relative to the general population. However, no HIV prevention interventions have been tested for efficacy with psychiatric patients in Brazil. We conducted participatory research with local providers, community leaders, patient advocates, and patients using an intervention adaptation process designed to balance fidelity to efficacious interventions developed elsewhere with fit to a new context and culture. Our process for adapting these interventions comprised four steps: (1) optimizing fidelity; (2) optimizing fit; (3) balancing fidelity and fit; and (4) pilot testing and refining the intervention. This paper describes how these steps were carried out to produce a Brazilian HIV prevention intervention for people with severe mental illness. Our process may serve as a model for adapting existing efficacious interventions to new groups and cultures, whether at a local, national, or international level

Heritability of physical activity traits in Brazilian families: the Baependi Heart Study

<p>Abstract</p> <p>Background</p> <p>It is commonly recognized that physical activity has familial aggregation; however, the genetic influences on physical activity phenotypes are not well characterized. This study aimed to (1) estimate the heritability of physical activity traits in Brazilian families; and (2) investigate whether genetic and environmental variance components contribute differently to the expression of these phenotypes in males and females.</p> <p>Methods</p> <p>The sample that constitutes the Baependi Heart Study is comprised of 1,693 individuals in 95 Brazilian families. The phenotypes were self-reported in a questionnaire based on the WHO-MONICA instrument. Variance component approaches, implemented in the SOLAR (Sequential Oligogenic Linkage Analysis Routines) computer package, were applied to estimate the heritability and to evaluate the heterogeneity of variance components by gender on the studied phenotypes.</p> <p>Results</p> <p>The heritability estimates were intermediate (35%) for weekly physical activity among non-sedentary subjects (weekly PA_NS), and low (9-14%) for sedentarism, weekly physical activity (weekly PA), and level of daily physical activity (daily PA). Significant evidence for heterogeneity in variance components by gender was observed for the sedentarism and weekly PA phenotypes. No significant gender differences in genetic or environmental variance components were observed for the weekly PA_NS trait. The daily PA phenotype was predominantly influenced by environmental factors, with larger effects in males than in females.</p> <p>Conclusions</p> <p>Heritability estimates for physical activity phenotypes in this sample of the Brazilian population were significant in both males and females, and varied from low to intermediate magnitude. Significant evidence for heterogeneity in variance components by gender was observed. These data add to the knowledge of the physical activity traits in the Brazilian study population, and are concordant with the notion of significant biological determination in active behavior.</p

Evaluating gene by sex and age interactions on cardiovascular risk factors in Brazilian families

Background: In family studies, it is important to evaluate the impact of genes and environmental factors on traits of interest. In particular, the relative influences of both genes and the environment may vary in different strata of the population of interest, such as young and old individuals, or males and females. Methods: In this paper, extensions of the variance components model are used to evaluate heterogeneity in the genetic and environmental variance components due to the effects of sex and age (the cutoff between young and old was 43 yrs). The data analyzed were from 81 Brazilian families (1,675 individuals) of the Baependi Family Heart Study. Results: The models allowing for heterogeneity of variance components by sex suggest that genetic and environmental variances are not different in males and females for diastolic blood pressure, LDL-cholesterol, and HDL-cholesterol, independent of the covariates included in the models. However, for systolic blood pressure, fasting glucose and triglycerides, the evidence for heterogeneity was dependent on the covariates in the model. For instance, in the presence of sex and age covariates, heterogeneity in the genetic variance component was suggested for fasting glucose. But, for systolic blood pressure, there was no evidence of heterogeneity in any of the two variance components. Except for the LDL-cholesterol, models allowing for heterogeneity by age provide evidence of heterogeneity in genetic variance for triglycerides and systolic and diastolic blood pressure. There was evidence of heterogeneity in environmental variance in fasting glucose and HDL-cholesterol. Conclusions: Our results suggest that heterogeneity in trait variances should not be ignored in the design and analyses of gene-finding studies involving these traits, as it may generate additional information about gene effects, and allow the investigation of more sophisticated models such as the model including sex-specific oligogenic variance components

Preliminarno ispitivanje antimikotskog i citotoksičnog djelovanja derivata cikloalkil[b]tiofena PLS-DA analizom

A series of 2-[(arylidene)amino]-cycloalkyl[b]thiophene-3-carbonitriles (2a-x) was synthesized by incorporation of substituted aromatic aldehydes in Gewald adducts (1a-c). The title compounds were screened for their antifungal activity against Candida krusei and Criptococcusneoformans and for their antiproliferative activity against a panel of 3 human cancer cell lines (HT29, NCI H-292 and HEP). Forantiproliferative activity, the partial least squares (PLS) methodology was applied. Some of the prepared compounds exhibited promising antifungal and proliferative properties. The most active compounds for antifungal activity were cyclohexyl[b]thiophene derivatives, and forantiproliferative activity cycloheptyl[b]thiophene derivatives, especially 2-[(1H-indol-2-yl-methylidene)amino]-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carbonitrile (2r), which inhibited more than 97 % growth of the three cell lines. The PLS discriminant analysis (PLS-DA)applied generated good exploratory and predictive results and showed that the descriptors having shape characteristics were strongly correlated with the biological data.Koristeći supstituirane aromatske aldehide u Gewaldovim aduktima 1a-c sintetizirani su derivati 2-[(ariliden)amino]-cikloalkil[b]tiofen-3-karbonitrila (2a-x). Ispitano je antimikotsko djelovanje tih spojeva na gljivice Candida krusei i Criptococcus neoformans te antiproliferativno djelovanje na tri humane tumorske stanične linije (HT29, NCI H-292 i HEP). Za antiproliferativno djelovanje primijenjena je metoda parcijalnih najmanjih kvadrata (PLS) koristeći softverski program Pentacle. Neki od ispitanih spojeva pokazuju obećavajuće antimikotsko i antiproliferativno djelovanje. Najjače antimikotsko djelovanje imaju cikloheksil[b]tiofen derivati, a najjače antiproliferativno djelovanje cikloheptil[b]tiofen derivati, posebice 2-[(1H-indol-2-il-metiliden)amino]-5,6,7,8-tetrahidro-4H-ciklohepta[b]tiofen-3-karbonitril (2r), koji inhibira više od 97 % rast svih triju ispitivanih staničnih linija. Primijenjena PLS diskriminirajuća analiza dala je dobre istraživačke i prognostičke rezultate i pokazala da deskriptori dobro koreliraju s biološkim rezultatima
