D-MELD does not predict post-liver transplantation survival: a single-center experience from Brazil
Background. The D-MELD score was designed to prevent donor-recipient matches with a high risk of unfavorable outcome. The main objective of the present study was to assess the predictive value of the D-MELD score for 1-month and 3-month post-transplant mortality in a cohort of patients who underwent deceased-donor liver transplantation in Southern Brazil.Material and methods. A cohort study was conducted. Receiver operating characteristic c-statistics were used to determine the ability of the D-MELD score to predict mortality. The Kaplan-Meier method was used to analyze survival as a function of time regarding D-MELD scores, and the Cox model was employed to assess the association between D-MELD and mortality.Results. Most recipients were male, with a mean age of 54.3 ± 9.6 years (n = 233 transplants). Mean donor age was 44.9 ± 16.8 years (19.3% of donors were aged ≥ 60 years). Mean MELD and D-MELD scores were 16.3 ± 7.1 and 733.1 ± 437.8 respectively. Overall survival at 1 and 3 months was 83.6%. The c-statistic value for 1- and 3-month mortality was < 0.5 for the D-MELD. Analysis of Kaplan-Meier curves for groups with D-MELD scores < 1,600 and ≥ 1,600 did not show statistically significant differences in survival (p = 0.722).Conclusion. D-mElD scores were unable to predict survival in this cohort of Brazilian liver transplant recipients
Concepções homofóbicas de estudantes do ensino médio
Este trabajo presenta los resultados de un estudio realizado con 2,159 estudiantes de secundaria de ambos los sexos a partir de tres ciudades en el interior del Estado de SĂŁo Paulo, Brasil. Los datos obtenidos mediante la escala Likert fueron analizados por la tĂ©cnica estadĂstica multivariante. Sobre el análisis de los factores, el mĂ©todo utilizado para la extracciĂłn de los factores fue el componente principal y el mĂ©todo de rotaciĂłn oblicua, en el que los seis factores obtenidos ayudan a la interpretaciĂłn de las posibles correlaciones entre las opiniones homofĂłbicas presentados en artĂculos. El estudio revelĂł que la tolerancia moderada para gays, lesbianas y transexuales en los jĂłvenes de la amuestra es una realidad que necesita la atenciĂłn de las polĂticas pĂşblicas en materia de educaciĂłn dirigidas a las estrategias para la deconstrucciĂłn de los estereotipos de gĂ©nero y la erradicaciĂłn de la homofobia, lesbofobia y transfobia entre los adolescentes.Este trabalho apresenta os resultados de um estudo realizado com 2.159 alunos e alunas do ensino mĂ©dio de trĂŞs cidades do interior paulista. Os dados, obtidos pelo uso de uma escala Likert, foram analisados por uma tĂ©cnica estatĂstica multivariada. Análise fatorial foi realizada, e seis fatores (extraĂdos pelo mĂ©todo das componentes principais e o mĂ©todo de rotação oblĂqua) favoreceram a interpretação das possĂveis correlações entre as concepções homofĂłbicas apresentadas nos itens. O estudo mostrou que a tolerância moderada em relação Ă homossexualidade dos jovens da amostra Ă© uma realidade que necessita de atenção das polĂticas pĂşblicas em educação, visando estratĂ©gias para a desconstrução de estereĂłtipos de gĂŞnero e erradicação da homofobia, lesbofobia e transfobia entre adolescentes.This paper presents the results of a study carried on with 2,159 male and female high school students from three cities in the countryside of SĂŁo Paulo State, Brazil. The data obtained by a Likert scale were analyzed by a multivariate statistical technique. Regarding the factor analysis, the method used for extracting the factors was the major component and oblique rotation method, in which the six factors obtained aid to interpreting the possible correlations among the homophobic views presented in items. The study revealed that moderate tolerance for gay, lesbian and transgender people in this young sample is a reality that needs attention of public policies in education targeting strategies for the deconstruction of gender stereotypes and eradication of homophobia, lesbophobia and transphobia among adolescents.Cet article prĂ©sente les rĂ©sultats d’une Ă©tude menĂ©e avec 2,159 lycĂ©ens et lycĂ©ennes provenants de trois villes Ă la campagne de l’État de SĂŁo Paulo, au BrĂ©sil. Les donnĂ©es obtenues par une Ă©chelle de Likert ont Ă©tĂ© analysĂ©es par une technique statistique multivariĂ©e. En ce qui concerne l’analyse factorielle, la mĂ©thode utilisĂ©e pour extraire les facteurs Ă©tait le principal composant et la mĂ©thode de rotation oblique, dans lequel les six facteurs obtenus ont aidĂ© Ă l’interprĂ©tation des corrĂ©lations possibles entre les points de vue prĂ©sentĂ©s dans les articles homophobes. L’étude a rĂ©vĂ©lĂ© que la tolĂ©rance modĂ©rĂ©e pour les homosexuels, les lesbiennes et les personnes transgenres dans ce jeune Ă©chantillon est une rĂ©alitĂ© qui a besoin d’attention des politiques publiques en matière d’éducation ciblant les stratĂ©gies pour la dĂ©construction des stĂ©rĂ©otypes de genre et l’éradication de l’homophobie, lesbophobie et la transphobie parmi les adolescents
