Food lists from the diet of a group of elderly individuals: analysis and perspectives

INTRODUÇÃO: A despeito do aumento expressivo da população idosa nos últimos anos, são escassos os estudos brasileiros relacionados ao consumo alimentar desses indivíduos. OBJETIVOS: Propor uma lista de alimentos mais consumidos por idosos residentes na Zona Leste de São Paulo e analisar os alimentos que contribuem para o consumo de nutrientes relevantes ao estado nutricional e, consequentemente, à saúde dos idosos. MÉTODOS: Foram avaliados 100 indivíduos acima de 60 anos, frequentadores de um centro de referência. Para caracterização do estado nutricional foi calculado o Índice de Massa Corporal (IMC). Para elaboração das listas de alimentos foram aplicados dois recordatórios alimentares de 24 horas (RA24h) em duas estações diferentes do ano, que foram analisados quanto à frequência de consumo de cada alimento e quanto à contribuição percentual de energia, macronutrientes, fibras, cálcio e vitamina D. RESULTADOS: Com relação ao estado nutricional, 52% apresentaram o IMC < 28 kg/m²; 15% entre 28 e 30 kg/m²; 26% entre 30 e 35 kg/m² e 7% com IMC &gt; 35 kg/m². O aspecto positivo da dieta foi a preservação de hábitos saudáveis como o consumo de arroz e feijão, e também de vegetais verde-escuros. Como aspecto negativo observou-se que a dieta dos idosos é monótona, pois poucos alimentos contribuem para o consumo de vários nutrientes. Além disso, houve um elevado consumo de carboidratos refinados em detrimento do consumo de alimentos integrais. CONCLUSÕES: As listas de alimentos obtidas, além de permitirem a reflexão sobre intervenções educativas, permitem o desenvolvimento subsequente de um Questionário de Frequência Alimentar específico para esse grupo.BACKGROUND: Despite the phenomena of population aging, Brazilian studies related to the feeding practices of elderly individuals are scarce. AIMS: To develop a list of the most ingested foods from community-dwelling elderly persons in the east-zone of São Paulo- Brazil and to analyse the foods that contribute most to relevant health-related nutrients of these individuals. METHODS: The study was performed with 100 individuals aged 60 years and above, registered at a local reference center. To describe the nutritional status, the weight and stature were measured and the BMI- body mass index was calculated. To develop the food lists, two 24h food recalls were applied, during two different seasons of the year. The food recalls were analysed for food intake frequency and for percentage contribution of each food and each nutrient: energy, macronutrients, calcium and vitamin D. RESULTS: The participants were classified as following: 52% with BMI < 28 kg/m²; 15% with BMI between 28 and 30 kg/m²; 26% between 30 and 35 kg/m² and 7% presented BMI&gt; 35 kg/m². The positive aspects related to food intake were rice, bean and green vegetable consumption. As negative aspects, we observed that the diet pattern was repetitive, since few foods contributed to a high number of nutrients. Furthermore, a high ingestion of refined carbohydrates was observed instead of whole foods. CONCLUSION: The food lists allowed reflecting on educative interventions, and also allow future development of different food frequency questionnaires that are specific for this group

IL-31 and IL-8 in Cutaneous T-Cell Lymphoma: Looking for Their Role in Itch

The itch associated with cutaneous T-cell lymphoma (CTCL), including Mycosis Fungoides (MF) and Sézary syndrome (SS), is often severe and poorly responsive to treatment with antihistamines. Recent studies have highlighted the possible role of interleukins in nonhistaminergic itch. We investigated the role of IL-31 and IL-8 in CTCL, concerning disease severity and associated itch. Serum samples of 27 patients with CTCL (17 MF and 10 SS) and 29 controls (blood donors) were analyzed for interleukin- (IL-) 31 and IL-8; correlations with disease and itch severity were evaluated. IL-31 serum levels were higher in CTCL patients than in controls and higher in SS than in MF. Also, serum IL-31 levels were higher in patients with advanced disease compared to those with early disease, and they correlated positively with lactate dehydrogenase and beta 2-microglobulin levels, as well as with the Sézary cell count. Itch affected 67% of CTCL patients (MF: 47%; SS: 100%). Serum IL-31 levels were higher in itching patients than in controls and in patients without itching. There was no association between serum IL-8 and disease severity, nor with itching. Serum IL-8 levels correlated positively with peripheral blood leukocyte and neutrophil counts in CTCL patients. Our study suggests a role for IL-31 in CTCL-associated itch, especially in advanced disease and SS, offering a rational target for new therapeutic approaches. Increased serum IL-8 observed in some patients may be related to concomitant infections, and its role in exacerbating itch by recruiting neutrophils and promoting the release of neutrophil proteases deserves further investigationinfo:eu-repo/semantics/publishedVersio

COMPARAÇÃO ENTRE OS TRATAMENTOS COM TANASE E COM GELATINA PARA CLARIFICAÇÃO DO SUCO DE CAJU ( Anacardium occidentale L.)

Comparou-se o tratamento da polpa do caju com tanase e com gelatina, visando à redução da turbidez e do teor de taninos. Os resultados indicaram que a redução das concentrações de taninos totais, hidrolisáveis, proantocianidinas e turbidez ficaram em 39%, 50%, 32% e 94% para sucos tratados com gelatina e 46%, 88%, 2% e 88% para a polpa tratada com tanase, respectivamente. Deste modo, o tratamento com gelatina foi eficiente para remoção de proantocianidinas, enquanto que o tratamento enzimático foi mais eficiente na redução de taninos hidrolisáveis. Os produtos obtidos não apresentaram diferenças visuais. Estudo comparativo de pré-viabilidade econômica mostrou que o investimento de capital para obtenção do suco de caju clarificado com enzima é menor que para o suco clarificado com gelatina. Entretanto, o custo de produção do suco de caju clarificado com gelatina é menor devido ao preço elevado da enzima tanase. COMPARISION OF THE CASHEW APPLE (Anacardium occidentale L.) JUICE CLARIFICATION WITH TANNASE AND GELATIN Abstract Tannase and gelatin were compared for treatment of cashew apple pulp aiming to reduce turbidity and tannin content. The results indicated that the decrease in concentrations of total tannin, hydrolysable tannin, proanthocyanidin, and turbidity was 39%, 50%, 32% and 94% for juices treated with gelatin and 46%, 88%, 2% and 88% for pulp treated with tannase, respectively. In this way the treatment with gelatin was more efficient to remove proanthocyanidin, whereas enzymatic ones was better for hydrolysable tannin decrease. The obtained products didnt present visual differences. The comparative economic analysis for the cashew-apple juice production showed that the capital investment for the enzymatic clarification is lower than for the conventional clarification process, using gelatin. Although, the cost of clarified cashew apple juice using gelatin is lower due to the high cost of the enzyme tannase

Perfil clínico e neuropsicológico de crianças com transtorno do deficit de atenção e hiperatividade

The aim of this study was to evaluate clinical and neuropsychological findings in children with suspicion of attention deficity hyperactivity disorder (ADHD). The assessment involved 150 children aged 7 to 14 referred to NANI at UNIFESP. RESULTS: 75 children (55 M and 20 F) fulfilled the criteria for ADHD, among which 35 were of the inattentive type, 28 of combined type and 12 were hyperactive/impulsive. There was negative correlation between the digit score and the Corsi test. Children with hyperactivity and impulsivity had a low performance for functional memory. Children with oppositional defiant disorder presented pattern changes in adaptability when there was a change in the rhythm the stimuli were presented and lower adaptation to time variability (Hit RT), in addition to higher rates of omission in the continuous performance test. CONCLUSION: This study suggests multiple interrelations between the scores of neuropsychological battery useful for detailed delimitation of the clinical profile of children with ADHD.O objetivo deste trabalho foi delimitar indicadores clínicos e neuropsicológicos em crianças com suspeita de transtorno do déficit de atenção e hiperatividade (TDA/H). Foram avaliadas 150 crianças (idade de 7 a 14 anos) encaminhados ao NANI da UNIFESP. RESULTADOS: 75 crianças (55 M e 20 F) preenchiam os critérios para o TDA/H, dentre os quais 35 (46,6%) pacientes eram desatentos, 28 do tipo combinado e 12 do tipo hiperatividade/impulsivo. Observou-se correlação negativa com o escore de dígitos e no escore do teste de Corsi. Crianças com hiperatividade e impulsividade apresentaram baixo desempenho nas funções relacionadas à memória operacional. Crianças com transtorno opositor desafiante apresentaram alterações nos padrões de adaptação às mudanças do ritmo com menor adaptação às variações do tempo de exposição aos estímulos (Hit RT), além de maiores taxas de omissão no teste contínuo de performance. CONCLUSÃO: Este estudo sugere múltiplas interrelacões entre os escores em provas neuropsicológicas que são úteis para uma delimitação do perfil clínico de crianças com TDAH.Universidade Federal de São Paulo (UNIFESP) Departamento de PsicobiologiaUNIFESP, Depto. de PsicobiologiaSciEL

Simplified Models for LHC New Physics Searches

This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS have already presented some results in terms of simplified models, and we encourage them to continue and expand this effort, which supplements both signature-based results and benchmark model interpretations. A simplified model is defined by an effective Lagrangian describing the interactions of a small number of new particles. Simplified models can equally well be described by a small number of masses and cross-sections. These parameters are directly related to collider physics observables, making simplified models a particularly effective framework for evaluating searches and a useful starting point for characterizing positive signals of new physics. This document serves as an official summary of the results from the "Topologies for Early LHC Searches" workshop, held at SLAC in September of 2010, the purpose of which was to develop a set of representative models that can be used to cover all relevant phase space in experimental searches. Particular emphasis is placed on searches relevant for the first ~50-500 pb-1 of data and those motivated by supersymmetric models. This note largely summarizes material posted at http://lhcnewphysics.org/, which includes simplified model definitions, Monte Carlo material, and supporting contacts within the theory community. We also comment on future developments that may be useful as more data is gathered and analyzed by the experiments.Comment: 40 pages, 2 figures.

Advancing Eucalyptus genomics: identification and sequencing of lignin biosynthesis genes from deep-coverage BAC libraries

<p>Abstract</p> <p>Background</p> <p><it>Eucalyptus </it>species are among the most planted hardwoods in the world because of their rapid growth, adaptability and valuable wood properties. The development and integration of genomic resources into breeding practice will be increasingly important in the decades to come. Bacterial artificial chromosome (BAC) libraries are key genomic tools that enable positional cloning of important traits, synteny evaluation, and the development of genome framework physical maps for genetic linkage and genome sequencing.</p> <p>Results</p> <p>We describe the construction and characterization of two deep-coverage BAC libraries EG_Ba and EG_Bb obtained from nuclear DNA fragments of <it>E. grandis </it>(clone BRASUZ1) digested with <it>Hind</it>III and <it>BstY</it>I, respectively. Genome coverages of 17 and 15 haploid genome equivalents were estimated for EG_Ba and EG_Bb, respectively. Both libraries contained large inserts, with average sizes ranging from 135 Kb (Eg_Bb) to 157 Kb (Eg_Ba), very low extra-nuclear genome contamination providing a probability of finding a single copy gene ≥ 99.99%. Libraries were screened for the presence of several genes of interest <it>via </it>hybridizations to high-density BAC filters followed by PCR validation. Five selected BAC clones were sequenced and assembled using the Roche GS FLX technology providing the whole sequence of the <it>E. grandis </it>chloroplast genome, and complete genomic sequences of important lignin biosynthesis genes.</p> <p>Conclusions</p> <p>The two <it>E. grandis </it>BAC libraries described in this study represent an important milestone for the advancement of <it>Eucalyptus </it>genomics and forest tree research. These BAC resources have a highly redundant genome coverage (> 15×), contain large average inserts and have a very low percentage of clones with organellar DNA or empty vectors. These publicly available BAC libraries are thus suitable for a broad range of applications in genetic and genomic research in <it>Eucalyptus </it>and possibly in related species of <it>Myrtaceae</it>, including genome sequencing, gene isolation, functional and comparative genomics. Because they have been constructed using the same tree (<it>E. grandis </it>BRASUZ1) whose full genome is being sequenced, they should prove instrumental for assembly and gap filling of the upcoming <it>Eucalyptus </it>reference genome sequence.</p
