OBJETIVO: comparar o conhecimento dos estudantes de Medicina da Liga do Trauma (LT) com os alunos Não Ligantes do Trauma (NLT), sobre os temas do atendimento ao trauma que os acadêmicos possuem maior domínio, avaliando a performance do conhecimento dos dois grupos.MÉTODOS: estudo transversal, analítico, descritivo. Aplicou-se teste de conhecimento para os alunos do terceiro ao 12º período. Desses, foram sorteados cinco acadêmicos de cada período, constituindo dois grupos: 50 no LT e 50 no NLT. Foram aplicados dois testes contento 30 questões para cada prova com os temas: atendimento pré-hospitalar, sequência mnemônica ABCDE do trauma, condutas avançadas e imagem no trauma. Avaliou-se a performance dos estudantes por grupo de períodos da graduação: cadeira básica (3º - 5º período), clínica (6º -8º) e internato (9º - 12º).RESULTADOS: no primeiro teste, a média de acertos do grupo LT foi 20,64±3,17 e 14,76± 5,28 no NLT (p<0,005). No segundo teste, a média do LT foi 21,52±3,64 e 15,36±5,29 no NLT (p<0,005). O grupo LT teve maior média de acerto nas três cadeiras da graduação (p<0,05), nos dois testes.CONCLUSÃO:o grupo LT teve maior média de acerto em relação ao NLT e melhor aproveitamento dos temas estudados em todas as fases do curso médico.

OBJECTIVE: to compare the knowledge of medical students between those who are members of the Trauma League (TL) and those from a non-Trauma League (NTL) group of the Federal University of Espírito Santo (UFES).METHODS: cross-sectional, analytical and descriptive study. Two knowledge tests, with 30 questions each, were applied to students from 3rd to 12th period, randomly selecting five students per period, with 50 students in the TL group and 50 in NTL. The questionnaire topics were: pre-hospital care, the mnemonic ABCDE trauma sequence, advanced trauma and imaging. The students' performances were evaluated by graduation-period group: basic (3rd-5th period), intermediary/clinical (6th-8th) and internship (9th-12th).RESULTS: in the first test the average accuracy of the TL group was 20.64 ± 3.17, while for the NTL group, it was 14.76 ± 5.28 (p<0.005). In the second test the average accuracy for the TL group was 21.52 ± 3.64, while for the NTL group, the average was 15.36 ± 29.5 (p<0.005). When divided into graduation periods, it was observed that the TL group showed a higher average across all three groups (p<0.05) in both tests.CONCLUSION: the students who attended the academic league activities have greater knowledge of the issues that are considered relevant to patient trauma care. In all periods of undergraduate academic training, the TL group had greater knowledge of the subject than the NTL group.

The QuEChERS extraction method followed by quantification using HPLC/UV-FL was evaluated for deoxynivalenol (DON) and zearalenone (ZEA) determination in natural and parboiled rice and their fractions (bran and husk). The comparison between QuEChERS and partition with acetonitrile extraction showed that the first one was better. It presented higher recovery (91% for DON, 105% for ZEA) wih precision ranging from 1.5 to 18.6%. The limits of quantification were 22.2 µg kg-1 for DON and 4.3 µg kg-1 for ZEA. DON and ZEA showed higher levels in endosperm of parboiled rice (8 e 111.7 µg kg-1, respectively) when compared to natural rice.

This study validated a simple and applied method for determining mycotoxins aflatoxin B1, aflatoxin B2, ochratoxin A, zearalenone and deoxynivalenol, in water from the rice production chain. Five solvent combinations for extraction were tested, with quantification performed by TLC/HPTLC and confirmation by LC-MS/MS. Mycotoxins in water from field and rice industries were evaluated. Mycotoxin recovery levels were around 90%. Two samples from rice parboiling waste were contaminated (deoxynivalenol/aflatoxin B1, 110/9 ng mL-1; and deoxynivalenol, 100 ng mL-1). Zearalenone, deoxynivalenol and ochratoxin A (36, 30 and 28%) were carried to soaking water during parboiling.

Considerando as perdas qualitativas e quantitativas no período pós-colheita de grãos, neste trabalho foram avaliadas a contaminação fúngica e as micotoxinas em arroz com casca, durante o sistema estacionário de secagem e armazenamento. As amostras foram coletadas em intervalos de 60 dias durante o armazenamento, em duas alturas do silo-secador. A amostra inicial apresentou 5,4x10(4)UFC g-1, sendo que a contagem aumentou significativamente durante a secagem e o armazenamento, chegando a 10(5)UFC g-1. A contaminação fúngica diferiu no interior do silo-secador, com maior contaminação na porção superior do silo. Os gêneros predominantes foram Aspergillus e Penicillium, com maior ocorrência de A. flavus (26,3%) e P. commune (19,1%). Quatro isolados de A. flavus produziram aflatoxina B1, mas não foram detectadas micotoxinas nas amostras.

Considering the qualitative and quantitative losses in post-harvest of grain, in this research was evaluated fungi and mycotoxins contamination in whole rice (Oryza sativa L.) during the stationary drying and storage system. Samples were collected in a period of sixty days in two heights of the warehouse during storage. The initial sample presented 5.4x10(4)CFU g-1; the contamination increased significantly during drying and storage, up to 10(5)CFU g-1. Fungi contamination was different inside the warehouse with higher contamination in the upper portion. The more abundant fungi genera were Aspergillus and Penicillium, A. flavus (26.3%) and P. commune (19.1%) which presented higher incidence. Aflatoxin B1 was produced by four A. flavus isolates, but mycotoxins were not detected in the samples.
