A avaliação do método “Salto Triplo” aplicado a estudantes do curso de Medicina

The present article aims to report an experience of tutors in performing a triple jump by evaluating the methodology of Problem-Based Learning (PBL) in a group of 37 students of the second period of a medical school of the Federal University of São Francisco Valley - UNIVASF, campus Paulo Afonso, Bahia, Brazil.The "triple jump" occurred in a daylight period, and was divided into three tutorial groups of nine students, a group of ten students and eight tutors. The problem situation was prepared by the tutors involved and all students were previously informed about the methodology applied. The assessment was divided into three stages (1-presentation of the problem; 2- individualized study; 3- Oral Presentation). In the end of the triple jump , it was applied an evaluative questionnaire and the 27 students had consented previously to fill them out. The students who participated in this application were able to quickly identify the learning objectives (94.6%). However, a small part of the participants (about 5%) suggested modifications on the time used to complete all the steps of the “Triple Jump”.The reported experience consolidate this evaluative tool has formative character and effective way in the measuring the teaching-learning process of students in health care in PBL methodby improving their educational background. O presente artigo tem como objetivo relatar a experiência vivenciada por tutores na realização de um salto triplo avaliando a metodologia de Aprendizagem Baseada em Problemas (ABP) em um grupo de 37 estudantes do segundo período do curso de medicina da Universidade Federal do Vale do São Francisco-UNIVASF, campus de Paulo Afonso, Bahia, Brasil. O “salto triplo” ocorreu em um período diurno, e foi dividida em três grupos de tutoria de nove alunos, um grupo com dez alunos e oito docentes. A situação-problema foi elaborada pelos tutores envolvidos e todos os estudantes foram previamente informados sobre a metodologia aplicada. A avaliação foi dividida em três etapas (1-apresentação do caso clínico; 2-Estudo individualizado; 3-Apresentação oral). No final do salto triplo, ainda foi aplicado um questionário avaliativo e 27 alunos consentiram em preenchê-lo. Os estudantes que participaram desta aplicação conseguiram identificar com rapidez os objetivos de aprendizagem (94,6%). No entanto, uma pequena parte dos estudantes participantes (cerca de 5%) sugeriram modificações quanto ao tempo estipulado para cumprimento das etapas do método. A experiência relatada reforça que esta ferramenta avaliativa tem caráter formativo eficaz na mensuração do processo de ensino-aprendizagem dos estudantes na área da saúde que estudam com ABP, aperfeiçoando sua formação educacional

In this report, the effects of the host’s nutritional status on parasite (worm load, egg viability and maturation) and host (growth curves, biology, collagen synthesis and characteristics of the immunological response) were studied and these are considered as interdependent factors influencing the amount and distribution of fibrous tissue in hepatic periovular granulomas and portal spaces. The nutritional status of the host influenced the low body weight and low parasite burden detected in UI mice as well as the number, viability and maturation of released eggs. The reduced oviposition and increased number of degenerated or dead eggs were associated with low protein synthesis detected in deficient hosts, which likely induced the observed decrease in transformation growth factor (TGF)-β1 and liver collagen. Despite the reduced number of mature eggs in UI mice, the activation of TGF-β1 and hepatic stellate cells occurred regardless of the unviability of most miracidia, due to stimulation by fibrogenic proteins and eggshell glycoproteins. However, changes in the repair mechanisms influenced by the nutritional status in deficient animals may account for the decreased liver collagen detected in the present study
