INDICADORES ANTROPOMÉTRICOS EM CRIANÇAS COM CÂNCER EM UM HOSPITAL DE REFERÊNCIA / ANTHROPOMETRIC INDICATORS IN CHILDREN WITH CANCER IN REFERENCE HOSPITAL

Introdução: A avaliação nutricional de crianças com câncer é de grande importância, e deve ser realizada no momento da internação,ou logo após o seu diagnóstico. Objetivo: Avaliar os indicadores antropométricos de crianças com câncer. Métodos:Estudo transversal analítico, realizado de janeiro a fevereiro de 2014, em um Hospital do Câncer no município de São Luís (MA).Foram coletados dados referentes ao gênero, idade, peso e altura e a partir desses foram realizados os indicadores antropométricos,peso por idade (P/I), Estatura por idade (E/I) e Índice de massa corporal por idade (IMC/I), cuja classificação obedeceu aoescore z. Resultados: Foram avaliadas 53 crianças e destas 81,1% meninos, 52,8% estavam na faixa etária de 7 a 8 anos e 54,7%com diagnóstico tumoral de leucemia. De acordo com o IMC/I houve uma predominância de crianças eutróficas (66,0%). O indicadorP/I, apresentou frequência de peso adequado para idade (67,9%) e 22,6% de risco nutricional (baixo peso P/I). Com relaçãoao indicador E/I, observou-se que 92,5% demonstraram estatura adequada para idade. Apresentaram risco nutricional,23,6% dos meninos e 20% das meninas (baixo P/I). Houve adequação da E/I em 90,7% dos meninos e em 100% das meninas.Conclusão: Em todos os indicadores antropométricos notou-se prevalência de eutrofia em relação à idade.Palavras-chave: Estado nutricional.

Objective: Assess anthropometric indicators of children with cancer. Methods: Analytical cross-sectionalstudy, conducted between January and February 2014 at a Cancer Hospital in São Luís, Maranhão, Brazil. Data regarding gender,age, weight and height were collected and from these the anthropometric indicators weight-for-age, height-for-age andbody mass index-for-age, these classifications the z- score. Results: Were evaluated 53 children, 81.1% were male, 52.8% in theage group 7-8 years old, 54.7% with primary tumor diagnosis of leukemia. According to the body mass index-for-age was apredominance of eutrophic children, with 66.0 %. The weight-for-age indicator, presented frequency appropriate weight for age(67.9%) and nutritional risk percentage (low weight for age), 22.6%. Regarding the indicator height-for-age, it was observed that92.5% demonstrated adequate height-for-age. They presented nutritional risk, with high percentage of appropriate weight forage, 23.6% of boys and 20% girls (Low weight-for-age). There was adequate height in relation to age for 90.7% of the boys and allthe girls (100%). Conclusion: In all anthropometric indicators was noted prevalence of normal weight in relation to age.Keywords: Nutritional Status. Cancer. Pediatrics

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Social determinants and their interference in homicide rates in a city in northeastern Brazil

OBJECTIVE: This paper aims to analyze the possible relationship between social determinants and homicide mortality in Fortaleza (CE), Brazil. METHOD: To investigate whether the rate of mortality by homicides is related to social determinants, an ecological study with emphasis on spatial analysis was conducted in the city of Fortaleza. Social, economic, demographic and sanitation data, as well as information regarding years of potential life lost, and Human Development Index were collected. The dependent variable was the rate of homicides in the period 2004 to 2006. In order to verify the relationship between the outcome variable and the predictor variables, we performed a multivariate linear regression model. RESULTS: We found associations between social determinants and the rate of mortality by homicides. Variables related to income and education were proven determinants for mortality. The multiple regression model showed that 51% of homicides in Fortaleza neighborhoods are explained by years of potential life lost, proportion of households with poor housing, average years of schooling, per capita income and percentage of household heads with 15 or more years of study. The coefficients for years of potential life lost and households with poor housing were positive. CONCLUSION: The findings indicate that the mortality by homicide is associated with high levels of poverty and uncontrolled urbanization, which migrates to the peripheries of urban centers

Identificação de áreas prioritárias para a vigilância e controle de dengue e outras arboviroses transmitidas pelo Aedes aegypti no município de Natal-RN: relato de experiência

Resumo OBJETIVO: relatar a experiência denominada vigi@dengue realizada no município de Natal-RN, Brasil, em out/2015-maio/2016. MÉTODOS: os indicadores entomológicos foram obtidos a partir das armadilhas de oviposição, e os indicadores epidemiológicos, das notificações no Sistema de Informação de Agravos de Notificação (Sinan-dengue) on-line, da busca ativa de casos e detecção de RNA viral (RTq-PCR) em artrópodes e amostras de soro humano; definiram-se níveis de risco baseados nesses indicadores, estabelecendo-se categorias de intervenções para cada nível. RESULTADOS: identificação precoce do surgimento de epidemia em três áreas da cidade, com orientação do trabalho de campo para áreas mais vulneráveis; Natal-RN apresentou índice de positividade de ovitrampas (IPO) de 40% e índice de densidade de ovos (IDO) de 51 ovos∕ovitrampa; identificou-se cocirculação dos arbovírus CHIKV, DENV-1 e DENV-3 em Natal-RN. CONCLUSÃO: a estratégia identificou precocemente o surgimento de epidemias localizadas; foi útil à orientação das medidas de controle para as áreas de maior risco
