Comparative study between two european inception cohorts of patients with early systemic lupus erythematosus

Objective To compare the main characteristics of two inception cohorts (Italian [ITC] and Spanish [SPC]) cohorts of patients with systemic lupus erythematosus (SLE) at the time of diagnosis and at one year of follow-up. Methods Demographic, clinical and immunological characteristics, and treatments at SLE diagnosis and at 12 months of follow-up of ITC and SPC were compared. Results One hundred and sixty-four patients in the ITC and 231 patients in the SPC were compared. the patients from ITC were younger at SLE diagnosis (41.1±15.0 years vs. 46.4±15.6 years; p<0.001) and had a higher prevalence of arthritis (62.8% vs. 45.5%; p=0.001), serositis (25.6% vs. 16.0%; p=0.026), neurological involvement (7.9% vs. 1.7%; p=0.006), and immunological abnormalities (anti-dsDNA, anti-Sm, antiphospholipid antibodies) (93.9% vs. 77.8%; p<0.001). Conversely, photosensitivity (29.5% in ITC vs. 45.9% in SPC; p=0.001) and oral ulcers (12.4% vs. 30.3%; p<0.001) were more frequent at onset of SLE in the Spanish patients. At the first 12 months of follow-up, these differences were maintained. At SLE onset, more Italian patients received glucocorticoids (85.4% vs. 50.2%; p<0.001) and immunosuppressive agents. At 12 months of follow-up, more Spanish patients were treated with antimalarials (75.6% in ITC vs. 90.0% in SPC; p<0.001). Conversely, the use of glucocorticoids was lower in SPC (89.0% in ITC vs. 57.1% in SPC; p<0.001). Conclusion These cohorts presented different profiles in terms of pattern of organ/system involvement and disease treatment, possibly as a consequence of patient selection or different disease management approaches between Italy and Spain

Aspectos morfológicos de folhas na diferenciação de variedades de carambola Morphological aspects of leaves in differentiation of varieties of star fruit

Em certas espécies vegetais, a distinção entre variedades pode ser realizada com base em aspectos morfológicos das folhas, o que permite a diferenciação mesmo quando não apresentam flores e/ou frutos. O presente trabalho foi realizado objetivando a distinção entre variedades de caramboleira (Averrhoa carambola L.) através de aspectos foliares. Foram avaliadas quatro variedades de caramboleira: Arkin, B-10, Golden Star e Hart, com quatro repetições de 10 folhas cada. Pelos resultados obtidos no presente trabalho, conclui-se que há diferenças morfológicas foliares entre as variedades de caramboleira, permitindo a sua distinção, especialmente em condições de viveiro.<br>In some vegetable species, the distinction among varieties can be done based on morphological aspects of the leaves that allow the differentiation even when they do not have flowers and/or fruits. The aim of this work was to differentiate the varieties of star fruit (Averrhoa carambola L.) by foliar aspects. It was evaluated four varieties of star fruit: Arkin, B-10, Golden Star and Hart, with four replications containing 10 leaves in each one. The results obtained showed that exist morphological foliar differences among the varieties of star fruit, being permitted the distinction, especially in nursery conditions

Caracterização morfológica e química de frutos de rambutan Morphologic and chemical characterization of rambutan fruits

Com a procura de alternativas por parte dos produtores e de novas opções pelos consumidores, o mercado de frutas exóticas tem ganhado cada vez mais espaço no Brasil. O rambutan encontra-se entre as frutíferas com potencial de mercado, sendo, no entanto, necessário maior conhecimento sobre a cultura, como adequada escolha de genótipos para cada região e manejo do pomar. Diante disso, realizou-se o presente trabalho, na Faculdade de Ciências Agrárias e Veterinárias - UNESP, Câmpus de Jaboticabal-SP, que teve por objetivo as caracterizações morfológica e química de frutos de rambutan, verificando a distinção de genótipos e distância genética entre os materiais. Foram avaliados: tamanho do fruto, comprimento dos filamentos, espessura da casca, tamanho da semente, peso do fruto, peso da casca, peso da semente, porcentagem de polpa, teores de sólidos solúveis (ºBrix), ácido ascórbico e acidez titulável. Realizaram-se ainda observações quanto a: coloração da casca, filamentos e polpa, aderência da polpa à casca, aderência da polpa à semente e presença de tegumento da semente na polpa. Com base nos resultados obtidos neste trabalho, pode-se concluir que os materiais A51 e B03 apresentam maior conjunto de características desejáveis, sendo promissores aos produtores na instalação de novos plantios da cultura.<br>With the increase in the search of alternatives by the producers, and of new options for the consumers, the market of exotic fruits has been gainig more space in Brazil. The rambutan is among the fruits with market potential, however it is necessary more knowledge about the culture, appropriate genotype choice for each area and handling of the orchard. Considering that, the present research was accomplished at the Faculdade de Ciências Agrárias e Veterinárias - UNESP, Campus of Jaboticabal, São Paulo State, Brazil, aiming to study the morphologic and chemical characterization of rambutan fruits, verifying the genotype distinction and the genetic distance among the materials. It was evaluated: fruit size, filament length, peel thickness, seed size, fruit, peel and seed weight, pulp percentage, soluble solid contents (ºBrix), ascorbic acid and titrable acidity. Morever, the following observations were conducted: peel coloration, filaments and pulp, adherence of the pulp to the peel, adherence of the pulp to the seed and presence of tegument of the seed in the pulp. Based on the obtained results in this research, it can be concluded that the materials A51 and B03 present a better group of desirable characteristics, revealing to be promising for the producers in the installation of new culture plantings
