Validation of the Grace Risk Score to Predict In-Hospital and 6-Month Post-Discharge Mortality in Patients with Acute Coronary Syndrome

Abstract Background The wide range of clinical presentations of acute coronary syndrome (ACS) makes it indispensible to use tools for risk stratification and for appropriate risks management; thus, the use of prognosis scores is recommended in the immediat clinical decision-making. Objective To validate the Global Registry of Acute Coronary Events (GRACE) score as a predictor of in-hospital and 6-month post-discharge mortality in a population diagnosed with ACS. Methods This is a prospective cohort study of consecutive patients diagnosed with ACS between May and December 2018. GRACE scores were calculated, as well as their predictive value for in-hospital and 6-month post-discharge mortality. The validity of the model was assessed by two techniques: discriminative power using the area under the receiver operating characteristic curve (AUC) and goodness-of-fit, using the Hosmer-Lemeshow (HL) test, at the 5% level of significance. Results A total of 160 patients were included, mean age 64 (±10.9) years; of which 60% were men. The risk model showed to have satisfactory ability to predict both in-hospital mortality, with an area under the curve (AUC) of 0.76 (95% confidence interval [CI], 0.57-0.95; p = 0.014), and 6-month post-discharge mortality, with AUC of 0.78 (95%CI, 0.62-0.94), p = 0.002. The HL test indicated good-fit for both models of the GRACE score. Conclusion In this study, the GRACE risk score for predicting mortality was appropriately validated in patients with ACS, with good discriminative power and goodness-of-fit. The results suggest that the GRACE score is appropriate for clinical use in our setting.

Academic performance and use of psychoactive drugs among healthcare students at a university in southern Brazil: cross-sectional study

ABSTRACT BACKGROUND: People have been using psychoactive substances for a long time. Over the last few years, this practice has spread among university students, who use these substances to improve their academic performance, relieve stress and increase concentration and memory. OBJECTIVES: To estimate the use of psychoactive drugs among healthcare students at a higher education institution in the city of Passo Fundo (RS), Brazil, and to ascertain the associated demographic and lifestyle factors. DESIGN AND SETTING: Cross-sectional study in a higher education institution. METHODS: We included 287 undergraduate medicine and dentistry students in this study. They answered a self-administered questionnaire regarding sociodemographic, lifestyle and health variables. The statistical analysis used univariate and bivariate analyses with Pearson's chi-square test (P-value < 0.05). ­Multivariate analyses were used to estimate odds ratios (OR) and their respective 95% confidence intervals. The SPSS software, version 20.0, was used. RESULTS: The prevalence of use of psychoactive substances among the students was 24.7%. Among these students, high frequencies of psychoactive drugs had been prescribed by physicians (95.8%) and for the purpose of relaxation or stress relief (73.2%). Women, medical students (compared with dental students) and participants with lower academic performance were more likely to use psychoactive drugs. After the multivariate adjustment, the "course" and "academic performance" remained associated with use of psychoactive drugs. CONCLUSION: There was high prevalence of psychoactive drug use among the students at the higher education institution investigated. Some variables (female sex, medical students and low academic performance) were associated with the outcome.

Qualidade do Pré-Natal no Brasil: Pesquisa Nacional de Saúde 2013 / Quality of Prenatal Care in Brazil: National Health Research 2013

Resumo O objetivo deste estudo foi avaliar a adequação do cuidado pré-natal no Brasil associado a determinantes sociodemográficos. A pesquisa consistiu em uma análise dos dados da Pesquisa Nacional de Saúde realizada no Brasil em 2013. Foram avaliados dois desfechos sobre a adequação do pré-natal, o índice de Kessner modificado por Takeda que, além de levar em consideração esse índice, avaliou se houve aferição da pressão arterial e do peso em todas as consultas, realização de algum exame de sangue e urina e ultrassom. Ambos indicadores de qualidade foram avaliados para o Brasil e também pelas macrorregiões do país. De acordo com o desfecho 1, 80,6% das mulheres realizaram o pré-natal adequado. Ao adicionarmos a realização de exames (Desfecho 2) o percentual foi 71,4%. O pré-natal adequado foi mais frequente entre as mulheres de cor branca e que realizaram o pré-natal na rede privada. A região norte apresentou as menores frequências de pré-natal adequado, enquanto a região sudeste as maiores. Apesar da ampla cobertura, o pré-natal no Brasil ainda apresenta iniquidades e baixa qualidade no atendimento, especialmente entre mulheres das regiões mais pobre do país.

Abstract This study aimed to assess the adequacy of prenatal care in Brazil associated with sociodemographic determinants. The study included a data analysis from the National Health Research performed in Brazil in 2013. Two outcomes on the adequacy of prenatal care were assessed: the Kessner index modified by Takeda index that, in addition to the former, assessed whether blood pressure and weight were measured in all appointments, as well as the performance of blood and urine tests and ultrasound. Both quality indicators were assessed for Brazil and for its macro-regions. According to Outcome 1, 80.6% of women received adequate prenatal care. When adding the performance of tests (Outcome 2), the rate dropped to 71.4%. Adequate prenatal care was more frequent among white women who performed prenatal care in the private health sector. The northern region had the lowest rate of adequate prenatal care, while the southeast region showed the highest rates. Despite the extensive coverage, prenatal care in Brazil still presents inequities and low service quality, especially for women from the poorest regions of the country.

Características contextuais de vizinhança e atividade física de lazer: Estudo Pró-Saúde / Neighborhood contextual characteristics and leisure-time physical activity: Pró-Saúde Study / Neighborhood contextual characteristics and leisure-time physical activity: Pró-Saúde Study

OBJETIVO Estimar a associação entre variáveis contextuais de vizinhança e prática de atividade física de lazer. MÉTODOS Foram analisados dados de 2.674 participantes adultos de estudo longitudinal no Rio de Janeiro, RJ, em 1999. A atividade física de lazer, avaliada de forma dicotômica, referiu-se às duas semanas prévias à pesquisa. Sexo, idade, renda, escolaridade e situação conjugal foram analisados como variáveis individuais. Características contextuais referentes às vizinhanças (bairros) foram índice de desenvolvimento social, índice de Theil e proporção de área de parques, praças e jardins, categorizadas em quintis. Foram estimadas razões de chances brutas e ajustadas e intervalos de confiança de 95% por meio de regressão logística multinível. RESULTADOS As prevalências de atividade física de lazer foram maiores entre residentes de bairros com maiores índices de desenvolvimento social (entre 32,3% e 55,4%) e proporção de área de parques, praças e jardins (entre 35,8% e 53,1%). Para o índice de desenvolvimento social, quando comparados aos residentes de bairros do primeiro quintil, as razões de chances ajustadas de atividade física de lazer para variáveis individuais foram 1,22 (IC95% 0,93;1,61), 1,44 (IC95% 1,09;1,89), 1,75 (IC95% 1,31;2,34) e 2,25 (IC95% 1,70; 3,00) entre residentes de bairros do segundo, terceiro, quarto e quinto quintis. As razões de chances relativas à proporção de área de parques, praças e jardins foram 0,90 (IC95% 0,69;1,19), 1,41 (IC95% 1,04;1,90), 1,63 (IC95% 1,24;2,14) e 1,05 (IC95% 0,80;1,38) entre residentes de bairros dos segundo, terceiro, quarto e quinto quintis. Após ajuste para as demais variáveis contextuais, somente o índice de desenvolvimento social ...

OBJECTIVE To estimate the association between neighborhood contextual variables and leisure-time physical activity. METHODS Data were analyzed for 2,674 adults from Rio de Janeiro, RJ, Southeastern Brazil, participating in the longitudinal study in 1999. Leisure-time physical activity in the two preceding weeks was assessed dichotomously. Sex, age, income, education and marital status were analyzed as individual variables. Neighborhood contextual characteristics were the social development index, the Theil index and the proportion of the area occupied by parks, squares and gardens, categorized in quintiles. The unadjusted and adjusted odds ratios and 95% confidence intervals were estimated using multilevel logistic regression. RESULTS The prevalence of leisure-time physical activity was higher in residents in neighborhoods with higher indices of social development (between 32.3% and 53.1%) and a greater proportion of parks, squares and gardens (between 35.8% and 53.1%). Regarding the social development index, the adjusted odds ratios for physical activity were 1.22 (95%CI 0.93;1.61), 1.44 (95%CI 1.09;1.89), 1.75 (95%CI 1.31;2.34) and 2.25 (95%CI 1.70;3.00) for residents in neighborhoods in the second, third, fourth and fifth quintiles, respectively, compared with residents in neighborhoods in the first quintile. The odds ratios for the proportion of parks, squares and gardens were 0.90 (95%CI 0.69;1.19), 1.41 (95%CI 1.04;1.90), 1.63 (95%CI 1.24;2.14) and 1.05 (95%CI 0.80;1.38) for residents in neighborhoods in the second, third, fourth and fifth quintiles. After adjusting for the other variables, only the social development index continued to be associated with leisure-time physical activity, with odds ratios of 1.41 (95%CI 1.02;1.95); 1.54 (95%CI 1.12;2.12); 1.65 (95%CI 1.14;2.39) and 2.13 (95%CI 1.40;3.25) for residents in neighborhoods in the second, third, fourth and fifth quintiles. CONCLUSIONS Leisure-time physical activity ...

Prevalência de diagnóstico médico auto-relatado de miomas uterinos em população brasileira: Padrões demográficos e socioeconômicos no Estudo Pró-Saúde / Prevalence of self-reported medical diagnosis of uterine leiomyomas in a Brazilian population: Demographic and socioeconomic patterns in the Pro-Saúde Study

Introdução: Os miomas uterinos (MU) são considerados os tumores mais comuns do sistema reprodutor feminino; no entanto, existem poucos estudos epidemiológicos sobre essa condição no Brasil. Objetivo: Estimar as prevalências de história auto-relatada de MU segundo características demográficas, socioeconômicas e de acesso a serviços de saúde. Métodos: Foram analisados dados de 1.733 trabalhadoras de universidade no Rio de Janeiro, participantes da linha de base do Estudo Pró-Saúde (1999-2001), em relação a três desfechos: (1) diagnóstico médico de MU, (2) MU com sintomas prévios ao diagnóstico e (3) casos que realizaram histerectomia pelo tumor. As prevalências e seus intervalos de 95% de confiança (IC 95%) foram estimadas em relação a estratos de variáveis demográficas (idade, cor/raça), socioeconômicas (escolaridade, renda) e marcadoras de acesso a serviços de saúde (teste Papanicolaou , exame de mama, plano de saúde). Resultados: A prevalência de diagnóstico médico de MU foi de 23,3% (IC 95% - 21,3; 25,2); a de MU com sintomas prévios ao diagnóstico, de 13,3% (IC 95% - 11,7; 15,0) e a de histerectomia pelo tumor, de 8,4% (IC 95% - 7,5; 10,3). Entre participantes abaixo de 45 anos de idade, foram observadas prevalências mais elevadas nos estratos de piores condições socioeconômicas e de cor/raça preta. Entre aquelas com 45 anos ou mais, foram encontradas maiores prevalências entre mulheres com melhor acesso a serviços de saúde. Conclusão: Entre as mulheres brasileiras investigadas, os MU constituem problema relevante de saúde, com prevalências ...

Introduction: Uterine leiomyomas (UL) are considered the most common tumors of the female reproductive system. However, there are few epidemiological studies about this condition in Brazil. Aim: To estimate the prevalence of self-reported history of UL according to demographic and socioeconomic characteristics, and to markers of access to health care. Methods: We analyzed data from 1,733 university employees who participated at the baseline waves of the Pro-Saude Study (1999-2001), in relation to three outcomes: (1) self-reported medical diagnosis of UL, (2) UL with symptoms prior to diagnosis, and (3) cases with hysterectomy due to UL. Prevalence and 95% confidence intervals (95% CI) were estimated in relation to strata of variables related to demographic (age, color/race) and socioeconomic characteristics (education, income) and of markers of access to health care (Pap smear, breast clinical exam and private health insurance status). Results: The prevalence of medically-diagnosed UL was 23.3% (95% CI - 21.3, 25.2), the UL with symptoms prior to diagnosis of 13.3% (95% CI - 11.7, 15.0) and hysterectomy due to UL, 8.4% (95% CI - 7.5, 10.3). Among participants younger than 45 years old, higher prevalence was observed among women with worse socioeconomic conditions and of black color/race. Among those with 45 years or more, there was higher prevalence among women with better access to health care. Conclusion: In this study population of Brazilian women, UL is a relevant health problem, and its prevalence and associated socio-demographic gradients are similar to those observed in other countries. .

Influência da posição sócio-econômica ao longo da vida nas desigualdades de cor/raça na ocorrência de miomas uterinos: estudo pró- saúde / Influence of socioeconomic position lifelong inequalities in color / race in the occurrence of uterine fibroids: pro-health study

Os miomas uterinos (MU) são considerados os tumores mais comuns dosistema reprodutor feminino. Estudos norte-americanos demonstram que mulheres negras são mais acometidas pelos MU que as de outros grupos étnico-raciais. No entanto, as causas da desigualdade racial na ocorrência dos tumores permanecem desconhecidas e possíveis mecanismos são pouco explorados na literatura. Em outra direção, devido às características dos MU (crescimento lento e longo períodode latência) parte considerável dos estudos epidemiológicos utilizam umdelineamento transversal, o que pode gerar problemas metodológicos, como osrelacionados à utilização da idade coletada transversalmente (posteriormente a ocorrência dos MU) como proxy da idade do surgimento dos tumores. Assim, este trabalho de tese foi dividido em três partes, como se segue. A primeira, com características descritivas, teve por objetivo estimar a ocorrência de MU autorelatadossegundo categorias demográficas e sócio-econômicas na população deestudo (compôs o artigo 1). A segunda, com componente analítico, propôs-se aavaliar o papel da PSE ao longo da vida como mediadora do efeito da cor/raça naocorrência de MU auto-relatados (compôs o artigo 2). A terceira, com caráter metodológico, teve por objetivo comparar medidas de associação, entre variáveis aferidas transversalmente, em análises que incluem a co-variável idade no momento da coleta de dados e análises que consideram a idade ao diagnóstico dos MU (compôs o artigo 3). Para tanto, foram analisados dados transversais da população feminina participante das duas etapas da linha de base do Estudo Pró-Saúde, referentes à história auto-relatada de diagnóstico médico de MU e ainda a características sócio-demográficas, da vida reprodutiva e de acesso a serviços de saúde...

Prevalência de sobrepeso e obesidade em trabalhadores de cozinhas dos hospitais públicos estaduais da Grande Florianópolis, Santa Catarina / Overweight and obesity prevalence in kitchen workers of public hospitals in Florianópolis, Santa Catarina, Brazil

Objetivo: Estimar as prevalências de sobrepeso e obesidade em trabalhadores de cozinhas hospitalares da Grande Florianópolis e verificar sua associação com características sociodemográficas. Métodos: Coleta de dados realizada através de questionário estruturado e levantamento de medidas antropométricas de peso e estatura em 200 trabalhadores, em atividade laboral regular. Resultados: A média do índice de massa corporal (IMC) nos trabalhadores ficou situada no grau de sobrepeso (27,7 kg/m2). As mulheres apresentaram prevalência de excesso de peso (IMC 25 kg/m2) três vezes maior, independentemente das demais variáveis, quando comparadas aos homens. As demais variáveis de exposição não estiveram associadas ao excesso de peso entre os trabalhadores.

Objective: The purpose of this study was to estimate the prevalence of overweight and obesity and verify its association with sociodemographic factors among hospital kitchen workers in public hospitals in Florianópolis, Brazil. Methods: All the participants (200 workers) answered a structured questionnaire and had anthropometric (height and weight) measures taken. Results: Workers average BMI was 27,7 kg/m2, considered as overweight. Prevalence of excess weight (BMI 25 kg/m2) was three times higher among women than men, independently of other factors. Other exposure variables were not associated with overweight among kitchen workers.
