    Nutrition in clinical practice - the refeeding syndrome: illustrative cases and guidelines for prevention and treatment

    No full text
    The refeeding syndrome is a potentially lethal complication of refeeding in patients who are severely malnourished from whatever cause. Too rapid refeeding, particularly with carbohydrate may precipitate a number of metabolic and pathophysiological complications, which may adversely affect the cardiac, respiratory, haematological, hepatic and neuromuscular systems leading to clinical complications and even death. We aimed to review the development of the refeeding syndrome in a variety of situations and, from this and the literature, devise guidelines to prevent and treat the condition. We report seven cases illustrating different aspects of the refeeding syndrome and the measures used to treat it. The specific complications encountered, their physiological mechanisms, identification of patients at risk, and prevention and treatment are discussed. Each case developed one or more of the features of the refeeding syndrome including deficiencies and low plasma levels of potassium, phosphate, magnesium and thiamine combined with salt and water retention. These responded to specific interventions. In most cases, these abnormalities could have been anticipated and prevented. The main features of the refeeding syndrome are described with a protocol to anticipate, prevent and treat the condition in adult

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Ciências Médicas, Florianópolis, 2012Introdução: A escolaridade é positivamente associada com a performance cognitiva de pessoas saudáveis e pacientes com doenças neurológicas, incluindo epilepsia. Particularidades socioculturais podem interagir com as variáveis relacionadas à epilepsia e levar a um baixo nível educacional. Esse estudo pretende investigar se os motivos da precoce interrupção da educação estão associados ao desempenho cognitivo de pacientes adultos com epilepsia do lobo temporal refratária com esclerose no hipocampo (ELTM-EH). Métodos: 61 pacientes consecutivos com ELTM-EH e com menos de nove anos de educação foram classificados de acordo com a causa da interrupção da educação, como: 1) limitações devido às crises (n = 23); 2) começar a trabalhar cedo (n = 16); 3) limitações financeiras (n = 11); 4) dificuldade de aprendizagem (n = 11). A associação independente entre esses quatro grupos de pacientes e a performance cognitiva em 25 testes neuropsicológicos foram investigadas por meio de uma análise de regressão linear múltipla. Resultados: Depois de controlar as variáveis demográficas, clínicas, de neuroimagem, eletrofisiológicas e anos de educação, os grupos da dificuldade de aprendizagem e de limitações devido às crises continuam independentemente associados com baixos escores nos testes de Vocabulário e Memória Lógica. Conclusão: Os motivos da precoce interrupção do estudo são preditores independentes do prejuízo de domínios cognitivos específicos em pacientes adultos com epilepsia com ELTM-EH. Uma intervenção precoce dos fatores responsáveis pela baixa escolaridade dos pacientes pode ajudar a sanar os déficits cognitivos na vida adulta.Abstract : Introduction: Schooling is positively associated with cognitive performance of healthy persons and patients with neurologic diseases including epilepsy. Socio-cultural particularities may interact with epilepsy related variables leading low schooling. This study investigated if the causes of early interruption of education were associated with cognitive performance in adults patients with refractory mesial temporal lobe epilepsy related to hippocampus sclerosis (MTEL-HS). Methods: Sixty one consecutive patients with refractory MTLE-HS and lower than 9 years of education were classified according to the cause of interruption of education as: 1) limitations due to seizures itself (n = 23); 2) start to work young (n = 16); 3) financial limitations (n = 11); 4) learning difficulties (n = 11). The independent association between these four patients groups and cognitive performance in 25 neuropsychological tests were investigated by linear multiple logistic regression analysis. Results: After controlling the demographic, clinical, neuroimaging, electrophysiological variables and years of education, the cause of earlier study interruption remain independently associated with lower scores in Vocabulary and Logical Memory tests. Conclusion: Causes of early study discontinuation are independent predictors of specific cognitive domains impairments in adult patients with refractory MTLE-SH. Early intervention on factors responsible for lower schooling of patients may help to remedy their cognitive deficits in adult life

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
