Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

Orientador: Cátia Regina Branco da Fonseca / Resumo: A criança com a Síndrome de Down (SD) apresenta maior incidência de diversas complicações clínicas e a deficiência de zinco tem sido considerada problema de saúde pública, levando a maiores prejuízos e repercussões negativas em funções bioquímicas, imunológicas e clínicas. O quadro clínico pode variar dentro de um amplo espectro de manifestações. Não se conhece, ao certo, a magnitude desta deficiência no Brasil. A avaliação criteriosa da alimentação é importante para que possamos avaliar as necessidades nutricionais específicas e realizar uma orientação visando a alimentação mais equilibrada. O objetivo foi avaliar o estado nutricional e o consumo alimentar, e verificar se há deficiência sérica de zinco em crianças com a Síndrome de Down. Estudo aprovado pelo Comitê de Ética em Pesquisa. Análise estatística realizada através do programa SPSS. Método: Estudo clínico transversal, em crianças com SD que realizam o seguimento no ambulatório de Pediatria Genética do Hospital das Clínicas de Botucatu (HCFMB). Foram realizados entrevista semiestruturada, recordatório alimentar de 24 horas (R24), avaliação nutricional (classificação segundo as curvas para SD) e dosagem de zinco sérica. Resultados: 84% dos incluídos receberam diagnóstico de eutrofia. No R24, verificou-se excesso do consumo de calorias e carboidratos, e sem deficiência no consumo de zinco. Quanto ao nível sérico do zinco, em 94,3% houve deficiência (considerado insuficiente valores abaixo de 65 μg/dL) com valor médio d...

The clinical presentation may vary in a broad spectrum of manifestations. The magnitude of this deficiency in Brazil is unknown. The careful evaluation of the diet is essential to access the specific nutritional needs and to guide the best medical conduct and orientations for a more balanced diet. The aim of this study was to evaluate the nutritional status and diet of children with DS, and research serum zinc deficiency. The study was approved by the Research Ethics Committe and statistical analysis was performed with SPSS program. Method: Cross-sectional clinical study with children with DS who performed follow-up at the Genetic Pediatrics outpatient clinics of Hospital das Clínicas de Botucatu (HCFMB). It was performed a semi-structured interview, 24-hour food diary (R24), nutritional assessment (classification according to the charts for DS) and serum zinc blood test. Results: 84% of the patients were diagnosed eutrophic. In the 24-hour food diary evaluation was detected an excess of calories and carbohydrate consumption, and no deficiency in zinc consumption. Regarding the serum zinc level, 94.3% had a deficiency (considered insufficient levels below 65 ug / dL) with a mean value of 50.40 ug / dL, median of 49.24 ug / dL (dp-10.0...

O objetivo deste trabalho foi analisar a dieta alimentar dos brasileiros. Para tal, estimouse o sistema de equações de demanda do consumidor por nutrientes e as elasticidades, que trazem informações sobre a sensibilidade do consumidor frente a variações nos preços e na renda. A base de dados utilizada foi a Pesquisa de Orçamentos Familiares (POF) de 2002/3, realizada pelo Instituto Brasileiro de Geografia e Estatística (IBGE). Utilizou-se o modelo QUAIDS para estimar as equações de demanda e as elasticidades preço e renda/dispêndio foram calculadas. A hipótese de não-linearidade do dispêndio total não foi rejeitada, ratificando a utilização do Modelo QUAIDS. Para os nutrientes lipídios, colesterol, proteína, vitaminas A e B e fibras alimentares, as elasticidades da demanda se reduziram com a evolução da renda, o que indica o consumo mais elevado destes nutrientes em domicílios mais ricos. Os carboidratos não apresentaram grande oscilação no consumo conforme a variação da renda. Sobre os efeitos dos preços no consumo de nutrientes, os que se mostraram mais sensíveis a mudanças de preços foram: carboidratos; cálcio; ferro; colesterol; e vitamina C, nutrientes estes que compõem os alimentos básicos brasileiros. / This work was carried out in order to analyze the Brazilian food diet by estimating the consumer demand system of equations for nutrients and their elasticities, which bring information about the consumer sensibility face to price and income changes. The database used was from Household Expenditure Survey (POF, 2002/03) produced by IBGE (Brazilian Bureau of Statistics). The QUAIDS model was used to estimate the equations for eleven nutrients. The hypothesis of the total income\'s non-linearity was not rejected, reaffirming the use of the QUAIDS\' Model. For lipids, cholesterol, protein, vitamins A and B and fibers, the income elasticities showed a decrease as income raises, this behavior indicates the higher consumption of these nutrients in richer households. The carbohydrates did not present much variation as income changes. When it comes to the price effect on the nutrients consumption, the results suggest that the most sensible nutrients were: carbohydrates; calcium; iron; cholesterol; and vitamin C. These nutrients represent most of the basic diet food in Brazil

Conceptually, the articulation among authors like Walter Benjamin, Roger Silverstone, Michel Maffesoli e Massimo Canevacci, building the experience of the fast-food culture. Methodologically, the view experience, allowing the analysis of different opinions about the communication impacts of the Giraffas network: the “geography” of the food court, the “ethnography” of the consuming practice and the “biography” of the consumer. For the corpus structure of the research, the West Plaza and Frei Caneca shopping centers, in São Paulo, selected by its geographical proximity (8 kilometers) and distance of cultural consumption. / O objetivo desta pesquisa é investigar as relações de comunicação e consumo que se estabelecem em lojas da rede de fast-food Giraffas em praças de alimentação de shopping centers, significativos pontos de encontro e de socialidade da contemporaneidade. Conceitualmente, a articulação entre autores como Walter Benjamin, Roger Silverstone, Michel Maffesoli e Massimo Canevacci, construindo a experiência da cultura fast-food. Metodologicamente, a experiência do olhar, permitindo a análise das diferentes grafias dos impactos da comunicação da rede Giraffas: a “geografia” da praça de alimentação, a “etnografia” da prática de consumo e a “biografia” do consumidor. Para a estrutura do corpus da pesquisa, os shoppings West Plaza e Frei Caneca, em São Paulo, selecionados por sua proximidade geográfica (oito quilômetros) e distância de consumo cultural.
