Dysglycemia, in this survey defined as impaired glucose tolerance (IGT) or type 2 diabetes, is common in patients with coronary artery disease (CAD) and associated with an unfavorable prognosis. This European survey investigated dysglycemia screening and risk factor management of patients with CAD in relation to standards of European guidelines for cardiovascular subjects. RESEARCH DESIGN AND METHODS The European Society of Cardiology's European Observational Research Programme (ESC EORP) European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE) V (2016-2017) included 8,261 CAD patients, aged 18-80 years, from 27 countries. If the glycemic state was unknown, patients underwent an oral glucose tolerance test (OGTT) and measurement of glycated hemoglobin A 1c. Lifestyle, risk factors, and pharmacological management were investigated. RESULTS A total of 2,452 patients (29.7%) had known diabetes. OGTT was performed in 4,440 patients with unknown glycemic state, of whom 41.1% were dysglycemic. Without the OGTT, 30% of patients with type 2 diabetes and 70% of those with IGT would not have been detected. The presence of dysglycemia almost doubled from that selfreported to the true proportion after screening. Only approximately one-third of all coronary patients had completely normal glucose metabolism. Of patients with known diabetes, 31% had been advised to attend a diabetes clinic, and only 24% attended. Only 58% of dysglycemic patients were prescribed all cardioprotective drugs, and use of sodium-glucose cotransporter 2 inhibitors (3%) or glucagon-like peptide 1 receptor agonists (1%) was small. CONCLUSIONS Urgent action is required for both screening and management of patients with CAD and dysglycemia, in the expectation of a substantial reduction in risk of further cardiovascular events and in complications of diabetes, as well as longer life expectancy.

Levantamento de plantas daninhas em área rotacionada com as culturas da soja, milho e arroz irrigado no cerrado de Roraima). As famílias com maior ocorrência foram as Amaranthaceae, Euphorbiaceae e Poaceae. Dentre as espécies, 82,60% pertencem à classe botânica das dicotiledôneas. Palavras-chave -Composição Florística. Matocompetição. Plantas invasoras.Abstract -This study had as its objective to identify and to quantify the levels of population density of the weeds species in crops rotated with soybean, rice, and corn in the savannah of The State of Roraima. Through the inventory square method, the identifi cation and count of the species was realized, with 30 sampling of 1m² in an area of 120 ha. Although some weeds have also been observed in other surveys in Brazil, some species were in insignifi cant levels of population in this survey, but were not considered as relevant, because the damage caused by weeds were infl uenced by both the density and the survivability of each species. The knowledge of the diversity and number of weeds in the crop is the fi rst step towards the realization of effective control. Therefore, it avoids unnecessary spending with inappropriate products and decreases the risks of environmental pollution arising from the misuse and abuse of herbicides. Twenty three species were identifi ed from 15 botanical families. The species with larger populations were Lindernia crustacea (288.667 plants ha ), and Physalis angulata (125.000 plantas ha -1 ). Families with higher prevalence were the Amaranthaceae, Euphorbiaceae and Poaceae. Within the species, 82.60% belong to the botanical class of dicots.

Resumo -Objetivou-se com este trabalho realizar a avaliação agroeconômica da produção consorciada de cultivares de feijão-caupi com cultivares de mandioca para mesa em uma área de cerrado do Estado de Roraima, visando o mercado de Boa Vista, em Roraima. O experimento foi instalado na área experimental do CCA/UFRR, no município de Boa Vista. Fez-se o plantio de duas cultivares de mandioca para mesa em 15 de agosto de 2007, em fi leira dupla, obedecendo ao espaçamento de 2,0 x 0,5 x 0,5 m, totalizando 16.000 plantas por hectare. Trinta dias após o plantio da mandioca para mesa, fez-se o plantio de quatro cultivares de feijão-caupi de porte semi-ereto entre as linhas duplas das cultivares de mandioca. O plantio foi realizado em sulcos, espaçados de 0,5 m, abertos manualmente por meio de enxada, deixando-se após desbaste, 8 plantas por metro. Adotou-se o delineamento experimental de blocos casualizados em esquema fatorial 2 x 4, com três repetições. Os termos do fatorial referem-se as duas cultivares de mandioca e as quatro cultivares de feijão-caupi. Conclui-se que as maiores receitas líquidas são encontradas no consórcio de todas cultivares de feijão-caupi com a mandioca Aciolina e o consórcio da mandioca Aciolina com a cultivar de feijão-caupi UFRR Grão Ve r de, apresenta a maior relação benefício/custo (6,07), considerando apenas os custos variáveis, na comercialização de vagem verde para a obtenção de grão verde.

Receitas líquidas.Abstract -This study has as its objective the agricultural and economical evaluation of the intercropped production of cowpea varieties with cassava in the savannah (cerrado) area of the State of Roraima, considering the market of Boa Vista, Roraima. The experiment was done in an experimental area of CCA/UFRR, within the municipality of Boa Vista. Two varieties of cassava were planted in August 15, 2007, in double rows, at the spacing of 2.0 x 0.5 x 0.5 m, in a total of 16.000 plants per hectare. Thirty days after the cassava was planted, four varieties of cowpea beans were randomly planted between the double rows of the cassava varieties. The planting was realized in furrows, of 0.5 m distant, manually dug with a hoe, having 8 plants each meter. The random blocks of experimental delineation in a factorial scheme of 2 x 4, with three repetitions, was used. It was concluded that the best liquid return was obtained in the intercropping of all the varieties of cowpea with the Aciolina cassava variety. Further, the intercropping between the Aciolina cassava variety and the UFRR Grão Ve r de cowpea variety, demonstrated the best cost/benefi t (6.07) relationship, when only the variable costs were considered during the commercialization of the green string bean to obtain green beans.

ABSTRACT:Nitrogen is considered the most limiting nutrient for cassava, and N availability can influence the crop cycle, including earlier harvest. The aim of this study was to study the effect of harvest time on the production components of cassava, "Aciolina" cultivar, at different rates of N fertiliser. The experiment was carried out in an area newly incorporated into the productive system in a savannah ecosystem in the northern Amazon. A randomised block experimental design was used in a split plot arrangement with four replications. The N rates (0, 30, 60, 150, and 330 kg ha -1 ) were allocated to the main plots, and the harvest times (90, 120, 150, 180, 240, 300, and 360 days after emergence of the stalks -DAE) were allocated to the subplots. Plant height, shoot fresh matter yield, number of roots per plant, average root diameter, and root fresh matter yield display an increasing linear response up to 360 DAE in cassava cv. "Aciolina". For all harvest times, the N rates promote an increase in root fresh matter yield. At 300 and 360 DAE, the root fresh matter and starch yield and the harvest index show a quadratic response as a function of the N level. The greatest efficiency of N topdressing on the production of root fresh matter occurs at 300 DAE, promoting an earlier harvest. At that time, the dose of maximum technical efficiency, 226 kg ha -1 N, results in a yield of 62 Mg ha -1 of root fresh matter, 13 Mg ha -1 of starch, and a harvest index of 81 %.

Roraima para o consumo in natura. Fez-se o plantio de seis clones de mandioca (Aciolina, Pão, Pão-do-Chile, Água Morna, Enxuta e Amazonas), em fileiras duplas, obedecendo ao espaçamento de 2,0 m x 0,8 m x 0,8 m, totalizando 8.928 plantas ha -1 . Utilizou-se o delineamento experimental em blocos casualizados com quatro repetições. Aos oito meses após o plantio realizou-se a colheita das raízes tuberosas, sendo avaliadas quanto ao teor de ácido cianídrico, teor de amido pelo método da balança hidrostática, teor de amido pelo método artesanal, capacidade de soltar a película e entrecasca, cor da entrecasca e cor da polpa crua. Os clones de mandioca foram classificados quanto ao teor de HCN em: Mansas (Enxuta e Pão-do-Chile), intermediárias (Aciolina e Água Morna) e Brava (Pão e Amazonas). O teor de amido obtido pelo método da balança hidrostática superestima o teor de amido pelo método artesanal. O clone Aciolina destacou-se entre os clones para consumo in natura, sendo também recomendado para uso industrial. Os clones Pão e Amazonas apresentam restrições tanto para o consumo in natura quanto para uso industrial. Palavra-chave -Ácido cianídrico. Características culinárias. Manihot esculenta.Abstract -The objective of this study was to characterize and identify cassava clones produced in Roraima State, Brazil, for human consumption. There was the planting of six clones of cassava (Aciolina, Pão, Pão-do-Chile, Água Morna, Enxuta and Amazonas), in double rows, following the spacing of 2.0 m x 0.8 m x 0.8 m, total of 8,928 plants ha -1 . It was used randomized blocks experimental design with four replications. At eight months after planting was carried out to harvest the roots, being evaluated for hydrocyanic acid, starch content by the method of hydrostatic balance and artisanal mining, ability to release the film and bark, bark color and flesh color raw. The cassava clones were classified according to HCN content in: Mansi (Enxuta and Pão-do-Chile), intermediate (Aciolina and Água Morna) and Brava (Pão and Amazonas). The starch obtained by the method of hydrostatic balance overestimates the starch content by the method artisanal mining. The Aciolina clone stood out among the clones for human consumption, it is also recommended for industrial use. The Pão and Amazonas clones have restrictions for both human consumption and for industrial used.

O presente trabalho visa analisar a orla oceânica dos balneários Mostardense, Mar Grosso, Cassino, Hermenegildo e Barra do Chuí, localizados no extremo sul do Brasil, do ponto de vista geomorfológico, como subsídio ao planejamento e gestão. Foram caracterizadas a barreira arenosa costeira (onde estão inseridos os balneários) e o sistema praia-duna das orlas urbanizadas. A partir disso, foram apontadas questões sobre o planejamento e gestão, enfatizando as dunas frontais. As áreas de estudo apresentam alguns aspectos semelhantes no âmbito do Quaternário costeiro e do sistema praia duna atual, havendo variações intrarregionais. Ao comparar as áreas, há relevantes aspectos distintos, podendo subdividir em orlas um pouco mais estáveis, onde as dunas conseguem se manter e até se desenvolver (Cassino e Mar Grosso), e orlas onde o mar avança mais, diminuindo ou até suprimindo as dunas situadas entre as áreas urbanizadas e a faixa de praia (Hermenegildo, Mostardense e Barra do Chuí).
