Full text linkDesempenho de indicadores antropométricos na predição de síndrome metabólica em idosos assistidos na atenção básica. 2018. 118f. Dissertação (Mestrado em Gerontologia Biomédica) – Escola de Medicina da Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, 2018. Introdução: A síndrome metabólica (SM) é frequente entre idosos e associa-se a desfechos negativos como morbidades cardiovasculares, câncer e mortalidade. Estudos têm demonstrado o desempenho de indicadores antropométricos na predição de síndrome metabólica, contudo, estudos envolvendo a população idosa em geral e brasileira em particular são insipientes. Objetivos: Descrever a frequência de SM e de seus componentes em idosos assistidos na atenção básica e determinar o desempenho de indicadores antropométricos na predição de síndrome metabólica. Métodos: Trata-se de um estudo com delineamento transversal, com 479 idosos que foram avaliados no Estudo Epidemiológico e Clínico dos Idosos Atendidos pela Estratégia Saúde da Família do Município de Porto Alegre (EMI-SUS). Para o diagnóstico de SM foi utilizado o critério NCEP-ATPIII revisado. As variáveis em investigação foram: SM e seus componentes (obesidade central, HDL-c diminuído e triglicerídios, pressão arterial e glicose elevados); variáveis demográficas (idade, sexo e faixa etária) e cinco indicadores antropométricos [circunferência do pescoço, diâmetro abdominal sagital (DAS), relação DAS/estatura (DAS/estatura), índice sagital e índice de conicidade]. O poder preditivo e os pontos de corte dos indicadores antropométricos foram determinados por meio de curvas Receiver Operating Characteristic (ROC). Os indicadores antropométricos que apresentaram área sob a curva (auROC) >0,70 foram considerados como desempenho adequado. Resultados: A maioria da amostra era do sexo feminino (63,5%) e apresentava SM (60,5%). O componente da SM mais frequente foi pressão arterial elevada (69,5%) e o menos frequente foi HDL-colesterol diminuído (34,9%). Na amostra total, os indicadores antropométricos que demonstraram desempenho adequado foram o DAS/estatura (ponto de corte:0,14; auROC:0,810; IC95%:0,771-0,850), DAS (ponto de corte:24,65 cm; auROC:0,777; IC95%:0,734-0,820) e índice de conicidade (ponto de corte:1,57; auROC:0,706; IC95%:0,660-0,753). No sexo feminino, os indicadores antropométricos com desempenho adequado foram o DAS (ponto de corte:23,34 cm; auROC:0,820; IC95%:0,766-0,875), DAS/estatura (ponto de corte:0,13; auROC:0,810; IC95%:0,755-0,865), circunferência do pescoço (ponto de corte:34,09 cm; auROC:0,782; IC95%:0,727-0,838) e índice de conicidade (ponto de corte:1,56; auROC:0,727; IC95%:0,666-0,788). No sexo masculino, os indicadores com desempenho adequado foram DAS/estatura (ponto de corte:0,14; auROC:0,768; IC95%:0,695-0,841), DAS (ponto de corte:25,04 cm; auROC:0,760; IC95%:0,685-0,835), e índice de conicidade (ponto de corte:1,61; auROC:0,724; IC95%:0,649-0,799). Conclusões: Os idosos atendidos na Estratégia Saúde da Família apresentaram elevada frequência de síndrome metabólica (60,5%). Observou-se que, dos cinco indicadores antropométricos investigados, três (DAS/estatura, DAS, e índice de conicidade) apresentaram bom desempenho na amostra total, quatro (DAS, DAS/estatura, circunferência do pescoço e índice de conicidade) nas mulheres e três nos homens (DAS/estatura, DAS e índice de conicidade). Ou seja, DAS, DAS/estatura e índice de conicidade mostraram-se adequados nos três segmentos.Performance of anthropometric indicators in the prediction of metabolic syndrome in elderly people attended basic care. 2018. 118f. Dissertation (Master in Biomedical Gerontology) - Escola de Medicina da Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, 2018. Introduction: Metabolic syndrome (MetS) is frequent among the elderly and is associated with negative outcomes such as cardiovascular morbidity, cancer and mortality. Studies have demonstrated the performance of anthropometric indicators in the prediction of metabolic syndrome, however, studies involving the elderly population in general and Brazilian in particular are insipient. Objectives: To describe the frequency of MetS and its components in elderly patients assisted in basic care and to determine the performance of anthropometric indicators in the prediction of metabolic syndrome. Methods: This is a cross-sectional study with 479 elderly people who were evaluated in the Epidemiological and Clinical Study of the Elderly Attended by the Family Health Strategy of the Municipality of Porto Alegre (EMI-SUS). For the diagnosis of MetS, the revised NCEP-ATPIII criterion was used. The variables under investigation were: MetS and its components (central obesity, decreased HDL-c and triglycerides, high blood pressure and glucose); (age, sex and age) and five anthropometric indicators (neck circumference, sagittal abdominal diameter (SAD), SAD/height ratio, sagittal index and conicity index]. The predictive power and cut-off points of the anthropometric indicators were determined using Receiver Operating Characteristic (ROC) curves. The anthropometric indicators that presented area under the curve (auROC)> 0.70 were considered as adequate performance. Results: The majority of the sample was female (63.5%) and had MetS (60.5%). The most frequent MetS was high blood pressure (69.5%) and the least frequent was decreased HDL cholesterol (34.9%). In the total sample, the anthropometric indicators that demonstrated adequate performance were SAD/height (cutoff point: 0.14, auROC: 0.810, 95% CI: 0.771-0.850), SAD (cut-off point: 24.65 cm, 0.777, 95% CI: 0.734-0.820) and conicity index (cut-off point: 1.57, aROC: 0.706, 95% CI: 0.660-0.753). In females, anthropometric indicators with adequate performance were the SAD (cut-off point: 23.34 cm, auROC: 0.820, 95% CI: 0.766-0.875), SAD/height (cutoff point: 0.13, auROC: 0.810 , 95% CI: 0.755-0.865), neck circumference (cutoff point: 34.09 cm, auROC: 0.782, 95% CI: 0.727-0.838), and conicity index (cutoff point: 1.56, auROC: 0.727; 95% CI: 0.666-0.788). In males, the indicators with adequate performance were SAD/height (cutoff point: 0.14, auROC: 0.768, 95% CI: 0.695-0.841), SAD (cutoff point: 25.04 cm, auROC: 0.760; %: 0.685-0.835), and conicity index (cutoff point: 1.61, auROC: 0.724, 95% CI: 0.649-0.799). Conclusions: The elderly attending the Family Health Strategy had a high frequency of metabolic syndrome (60.5%). It was observed that, of the five anthropometric indicators investigated, three (SAD/height, SAD, and conicity index) performed well in the total sample, four (SAD, SAD/height, neck circumference and conicity index) in women and three in men (SAD/height, SAD and conicity index). That is, SAD, SAD/height and conicity index were adequate in all three segments
Sensibilidade gustativa em idosos: uma revisão narrativa = Gustative sensitivity in elderly: a narrative review
Full text linkObjetivo: Realizar uma revisão narrativa referente ao paladar e os diversos aspectos relacionados às alterações gustativas no envelhecimento, bem como o manejo nutricional. Fontes de dados: Foi realizada uma pesquisa bibliográfica na base de dados PubMed no período de março a julho de 2017. Para execução da busca, utilizaram-se os termos “taste perception”, “taste disorders”, “taste threshold”, “taste bud”, “elderly” com auxílio de operadores booleanos (AND e OR). Resumo dos achados: Um dos primeiros receptores envolvidos na identificação e avaliação dos alimentos é o receptor gustativo. Com o envelhecimento, ocorre uma perda de paladar devido a mudanças nas membranas das células gustativas envolvendo função alterada de canais iônicos e receptores sensoriais além da redução do número de botões gustativos numa papila gustativa. Estas desordens podem estar associadas a diversas condições, dentre elas, a polifarmácia, tabagismo, álcool, higiene bucal inadequada e doenças debilitantes como doença renal e hepática, câncer, infecções respiratórias, AIDS e diabetes mellitus, doença de Parkinson e distúrbios cognitivos. Medidas simples como o uso de condimentos e temperos naturais, aumento da ingestão hídrica, mastigação adequada e higiene bucal apropriada podem trazer grandes benefícios ao evitar ou contornar alterações gustativas no idoso, sendo fundamental a atuação do nutricionista. Conclusões: É essencial compreender as alterações na função gustativa que permeiam o processo de envelhecimento a fim de detectar precocemente essas alterações e contribuir para uma melhor qualidade de vida dos idoso

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
