Abnormalities of the inferior vena cava are rare. Its embryological development occurs between the sixth and eighth week of gestation and depends on the persistence or regression of three pairs of veins: the posterior cardinal veins, the subcardinal veins and the supracardinal veins. The type of congenital alteration depends on the moment that embryogenesis is altered. The most frequent clinical presentation is deep vein thrombosis, which occurs mainly in young men. We report a 16-year-old male presenting with edema of the left leg. No risk factor for thrombosis was recorded. A Doppler ultrasound confirmed the presence of a deep femoro-popliteal vein thrombosis. An abdominal CAT scan showed an agenesis of the supra and infra-adrenal inferior vena cava, with multiple collaterals. The study for thrombophilia was negative. The patient was treated with vitamin K antagonists with a good clinical response.

ABSTRACT: The quality of sparkling wine reflects the climate and management of vineyard, since these factors affect grape development, berry composition, and base wine composition. ‘Chardonnay’ vines were subjected to five in-row spacing distances (0.5; 0.75; 1.0; 1.50; and 2.0 m) combined with and without shoot thinning. For each in-row spacing, vines were thinned to 5, 8, 10, 15, and 20 shoots per plant. Vegetative growth, yield, berry composition and base wine composition were analyzed for two years. Vines with decreased in-row spacing, presented fewer clusters and malic acid content in berries, mostly related to the shading effect. Shoot thinning increased bud fruitfulness and decreased leaf area per meter, leaf area per plant, and leaf layer number. In-row spacing from 1.5 m to 0.5 m showed promising results for the Southeast Brazil with higher yield per hectare and sufficient acidity to provide freshness in sparkling wines.

Resumo Buscou-se investigar as concepções de coordenadores de cursos de uma universidade pública brasileira acerca dos determinantes da evasão e reprovação e as estratégias de intervenção desenhadas para intervir nesses fenômenos. Foram entrevistados individualmente coordenadores de 10 cursos de graduação com elevados índices de reprovação e evasão. Percebeu-se que a evasão e a reprovação são aspectos claramente diagnosticados no cotidiano dos entrevistados, contudo os relatos apresentaram discrepâncias na eleição de determinantes e nas estratégias adotadas ou planejadas para o enfrentamento da questão. De modo geral, os determinantes da evasão e reprovação citados foram, prioritariamente, externos ao curso. Ainda, a maioria dos cursos não realizava avaliações institucionais, assim a coordenação não possuía um diagnóstico contextual do problema. Percebeu-se nas entrevistas iniciativas isoladas e bem intencionadas que buscavam minimizar problemas, mas que podem ter efetividade reduzida uma vez que estavam desarticuladas dos planos estratégicos da universidade.

Abstract This research investigated the concepts of course coordinators from a Brazilian public university about the determinants of dropout and academic failure rates and about intervention strategies designed to fight these phenomena. Were individually interviewed coordinators of 10 undergraduate courses with high failure and dropout rates. It was noticed that evasion and failure are academic aspects clearly diagnosed in the respondents routine, however reports showed discrepancies in the election of determinants and strategies adopted or planned to address the issue. In general, the determinants of evasion and failure cited were primarily external to the course. Also, most of the courses did not have institutional evaluations, thus coordination lacked a contextual diagnosis of the problem. Isolated and well-intentioned initiatives that sought to minimize problems were identified, but that may have reduced effectiveness since they were apart from university strategic planning.

Há um interesse crescente dos jovens universitários em participar de organizações estudantis como estratégia de preparação para o mercado de trabalho. O objetivo deste trabalho foi realizar uma pesquisa exploratória dessas experiências e seus resultados para os alunos que delas participaram. Foi utilizado como método de pesquisa o estudo de caso, e os resultados indicam que o papel que a organização estudantil desempenhou na vida desses jovens centrou-se muito mais em uma tentativa de suprir a angústia frente ao sentimento constante de insuficiência e às demandas do mercado de trabalho na atualidade que em uma vivência que de fato tenha incrementado a sua empregabilidade.

There is growing interest of young graduates to participate in student organizations as a strategy to prepare for labor markets. The aim of this study was an exploratory study of these experiments and their results for students who attended them. We took as research method the case study and the results indicate that the role that student organization has played in the lives of these young people focused more on an attempt to overcome the anguish and constant feeling of inadequacy and the demands of the labor market today than in a experience that actually increased their employability.
