    We propose a method for the analysis of functional data with complex dependencies, such as spatially dependent curves or time dependent surfaces, over highly textured domains. The models are based on the idea of regression with partial differential regularizations. In particular, we consider here two roughness penalties that account separately for the regularity of the field in space and in time. Among the various modelling features, the proposed method is able to deal with spatial domains featuring peninsulas, islands and other complex geometries. Space-time varying covariate information is included in the model via a semi-parametric framework. The proposed method is compared via simulation studies to other spatiotemporal techniques and it is applied to the analysis of the annual production of waste in the towns of Venice province

    OBJETIVO: Estimar o consumo de energia e de macronutrientes no domicílio e na escola em tempo integral em crianças de 2 a 6 anos e pesquisar diferenças no consumo entre as crianças de escolas públicas e particulares. MÉTODOS: Estudo transversal realizado com 362 pré-escolares em Caxias do Sul (RS). O estado nutricional foi avaliado pela razão peso para estatura. O consumo na escola foi avaliado por meio do método de pesagem direta individual dos alimentos consumidos pelas crianças e, no domicílio, por meio do método de registro alimentar realizado pelos pais ou responsáveis. Para as análises estatísticas utilizou-se o teste U de Mann-Whitney (p < 0,05). RESULTADOS: Observou-se que 28 crianças (7,7 por cento) apresentaram excesso de peso, 92 (25,4 por cento), risco para excesso de peso e sete (1,9 por cento), baixo peso para a estatura. A avaliação da ingestão alimentar em 24 horas mostrou que 51,3 por cento da energia, 60,3 por cento dos lipídios e 51,6 por cento das proteínas foramconsumidos nos domicílios, apesar de as crianças permanecerem em período integral nas escolas. Observou-se maior ingestão de energia (p = 0,001), carboidratos (p < 0,001) e lipídios (p = 0,04) nos pré-escolares de escolas particulares em relação aos de escolas públicas, porém o consumo total diário se mostrou similar nas diferentes instituições. CONCLUSÕES: Os achados sugerem que as crianças consomem proporcionalmente mais energia, proteínas e lipídios nas refeições complementares dos domicílios em relação às refeições diárias nas escolas infantis. Apesar das diferenças de consumo entre as escolas públicas e particulares, a ingestão diária mostrou-se similar entre as criançasOBJECTIVE: To estimate the energy and macronutrient intake at home and at all-day in the kindergarten programs in children aged 2 to 6 and to investigate differences in consumption and intake between children at public and private kindergartens. METHODS: This was a cross-sectional study of 362 preschool children from Caxias do Sul, Brazil. Nutritional status was assessed in terms of weight to height ratios. Foods consumed in the kindergarten were evaluated by weighing the actual foods eaten by the children and home intakes were calculated from a food diary kept by parents or guardians. Statistical analyses were performed using the Mann-Whitney U test (p < 0.05). RESULTS: It was found that 28 children (7.7%) were overweight, 92 (25.4%) were at risk of becoming overweight and seven (1.9%) were classified as having wasting. Analysis of 24-hour nutritional intake demonstrated that 51.3% of the energy, 60.3% of the lipids and 51.6% of the proteins consumed by children were eaten at home, despite the children spending the whole day in the kindergarten programs. Preschool children at kindergartens ate greater quantities of energy (p = 0.001), carbohydrates (p < 0.001), and lipids (p = 0.04) than did children at public kindergartens, but their total daily intakes were similar, irrespective of which type of kindergarten program children attended. CONCLUSIONS: The findings suggest that these children eat proportionally more energy, proteins and lipids in their extra meals at home than they do in their daytime meals in the kindergarten programs. Despite the differences in intake between public and private kindergarten, daily intakes were simila

    OBJETIVO: Avaliar a ingestão alimentar de micronutrientes em pré-escolares no domicílio e em escolas de educação infantil públicas e particulares. MÉTODOS: Estudo transversal realizado com 362 pré-escolares entre dois e seis anos de idade, em Caxias do Sul (RS) Brasil, em 2007. A ingestão alimentar na escola foi avaliada por meio do método de pesagem direta individual, e no domicílio, por meio de registro alimentar realizado pelos pais ou responsáveis. Foi calculada a ingestão alimentar de cálcio, ferro, folato, vitamina A, vitamina C e zinco de acordo com o local da refeição e tipo de escola. RESULTADOS: Houve maior ingestão de alimentos contendo ferro, folato e vitamina C durante o período em que as crianças permaneceram na escola infantil, e maior ingestão de cálcio, vitamina A e zinco no domicílio. Houve significativamente maior ingestão de alimentos contendo ferro (p=0,03), folato (p=0,03), vitamina A (p<0,01) e vitamina C (p<0,01) pelas crianças da escola particular e maior ingestão de cálcio (p<0,01) e zinco (p<0,01) na escola pública. Quanto à prevalência de inadequação dos micronutrientes, as crianças não apresentaram risco deficiente para ingestão de ferro, folato, vitamina A e C e zinco, porém apenas 67,4% apresentaram ingestão de cálcio igual ou acima ao valor de referência. CONCLUSÃO: Os achados sugerem que o consumo de cálcio, vitamina A e zinco foi maior nos domicílios, apesar de as crianças permanecerem a maior parte do dia nas escolas. O consumo diário de micronutrientes de crianças de escolas públicas e particulares não diferiu significativamente, mesmo com diferenças nos cardápios.OBJECTIVE: This study assessed the adequacy of preschool children's dietary micronutrient intake at home and in public and private kindergartens. METHODS: This cross-sectional study done in 2007 included 362 preschool children aged 2-6 years from Caxias do Sul (RS), Brazil. Food intake at school was assessed by the individual direct weighing method and at home by food records kept by the parents or caregivers. Dietary intakes of calcium, iron, folate, vitamin A, vitamin C and zinc were calculated according to meal location and type of school. RESULTS: Dietary iron, folate and vitamin C intakes were higher in kindergartens and dietary intakes of calcium, vitamin A and zinc were higher at home. Dietary intakes of iron (p=0.03), folate (p=0.03), vitamin A (p<0.01) and vitamin C (p<0.01) were significantly higher in private kindergartens and dietary intakes of calcium (p<0.01) and zinc (p<0.01) were significantly higher in public kindergartens. Intakes of iron, folate, vitamin A, vitamin C and zinc were adequate but only 67.4% of the children were ingesting enough calcium. CONCLUSION: Dietary intakes of calcium, vitamin A and zinc were higher at home even though the children remained at school during most of the day. The daily micronutrient intakes of children from private and public kindergartens were not significantly different despite the menu differences

    Hyponatremia influences the outcome of patients with acute-on-chronic liver failure: an analysis of the CANONIC study

    Get PDF
    INTRODUCTION: Hyponatremia is a marker of poor prognosis in patients with cirrhosis. This analysis aimed to assess if hyponatremia also has prognostic value in patients with acute-on-chronic liver failure (ACLF), a syndrome characterized by acute decompensation of cirrhosis, organ failure(s) and high short-term mortality. METHODS: We performed an analysis of the Chronic Liver Failure Consortium CANONIC database in 1,341 consecutive patients admitted to 29 European centers with acute decompensation of cirrhosis (including ascites, gastrointestinal bleeding, hepatic encephalopathy, or bacterial infections, or any combination of these), both with and without associated ACLF (301 and 1,040 respectively). RESULTS: Of the 301 patients with ACLF, 24.3% had hyponatremia at inclusion compared to 12.3% of 1,040 patients without ACLF (P <0.001). Model for end-stage liver disease, Child-Pugh and chronic liver failure-SOFA scores were significantly higher in patients with ACLF and hyponatremia compared to those without hyponatremia. The presence of hyponatremia (at inclusion or during hospitalization) was a predictive factor of survival both in patients with and without ACLF. The presence of hyponatremia and ACLF was found to have an independent effect on 90-day survival after adjusting for the potential confounders. Hyponatremia in non-ACLF patients nearly doubled the risk (hazard ratio (HR) 1.81 (1.33 to 2.47)) of dying at 90 days. However, when considering patients with both factors (ACLF and hyponatremia) the relative risk of dying at 90 days was significantly higher (HR 6.85 (3.85 to 12.19) than for patients without both factors. Patients with hyponatremia and ACLF had a three-month transplant-free survival of only 35.8% compared to 58.7% in those with ACLF without hyponatremia (P <0.001). CONCLUSIONS: The presence of hyponatremia is an independent predictive factor of survival in patients with ACLF. In cirrhosis, outcome of patients with ACLF is dependent on its association with hyponatremia
