Religion and sociodemographic characteristics at baseline of the Brazilian Longitudinal Study of Adult Health study.

OBJECTIVE: The aim of this study was to investigate whether sex, age, race, income, education, and marital status are associated with having a religion in a sample of Brazilian men and women. METHODS: Data were obtained from 15,098 participants of the Brazilian Longitudinal Study of Adult Health, a longitudinal study that ultimately aims to investigate long-term outcomes of chronic diseases. The sociodemographic characteristics and data on religion status were self-reported during interviews conducted by trained personnel. All study procedures followed standard and validated protocols. RESULTS: There was a strong association between being a woman and having a religion (adjusted OR=2.12, 95%CI 1.95-2.31) when compared to men. Regarding age, those with 45-54 years were more likely to have a religion (adjusted OR=1.14, 95%CI 1.03-1.27). Blacks and Browns were more religious (adjusted OR=1.31, 95%CI 1.15-1.49, and OR=1.22, 95%CI 1.10-1.34, respectively) compared to Whites. Those with high income and education were less likely to state having a religion (adjusted OR=0.78, 95%CI 0.70-0.87, and adjusted OR=0.50, 95%CI 0.43-0.59, respectively). Those who did not have a stable conjugal union were found to be less religious (adjusted OR=0.82, 95%CI 0.75-0.89). Stratifying the analysis according to income showed that higher education was inversely associated with religion on both strata: lower and higher annual earnings. CONCLUSION: This study suggests that education is one of the most important socioeconomic characteristics to consider when studying religion. Race, sex, income, and marital status are also important factors; however, there was not a clear association between religion and age.

Potential Determinants of Thyroid Peroxidase Antibodies and Mortality Risk: Results From the ELSA-Brasil Study.

CONTEXT: The presence of thyroid peroxidase antibodies (TPOAbs) may be considered as an indicator of adverse health outcomes. OBJECTIVE: We aimed to investigate the potential determinants of TPOAb levels and to analyze the association between TPOAb titers and the risk of all- and specific-cause mortality. METHODS: Baseline and longitudinal data of 13 187 participants from the ELSA-Brasil Study were analyzed. We investigated the association of TPOAb, detectability, positivity, and persistent positivity with sociodemographic and lifestyle factors using logistic regressions. Cox proportional hazards and Fine-Gray subdistribution hazard regression analyses were used to verify the association of TPOAbs with mortality. RESULTS: The determinants of TPOAb detectability and positivity were younger age, higher body mass index, female sex, and former and current smoking status. Black, mixed, and other self-reported races, intermediate and higher education, and heavy drinking were determinants of detectable and positive TPOAb levels. Female sex, White race, and former smoking were determinants of persistent TPOAb positivity at 2 visits, although only the female sex maintained its association at 3 visits. Moreover, after multivariate adjustment, there were associations between higher levels of TPOAbs and higher risk of cancer-related mortality among men, and TPOAb detectability and mortality by other causes among women. CONCLUSION: Sociodemographic and lifestyle-related factors were determinants of multiple TPOAb categories. TPOAb levels were associated with mortality risk; however, the low mortality rate in this sample might have compromised this finding. We suggest further studies to explore the clinical importance of detectable TPOAb levels, not only its positivity, as a potential marker of inflammation.

Remote vs. face-to-face activities in the teaching of renal pathophysiology in the context of social isolation during the early phase of the COVID-19 pandemic.

The advent of the COVID-19 pandemic forced medical schools around the world to adopt emergency remote learning as a resort to avoid interruption of courses. However, the effectiveness of online classes as an educational strategy has been questioned by medical educators and students. In a prospective observational study design, students enrolled in a renal physiology and pathophysiology course were exposed to either face-to-face or remote synchronous classes. Students taught online obtained significantly higher mean scores than the group who had in-person classes, both groups assessed with identical exams. Appropriate screening tests suggested that fraud is unlikely to have significantly influenced these results and that the observed differences in performance reflected increased learning by the remote group. These observations suggest that online classes can help to maintain the continuity of physiology and pathophysiology courses during periods of social isolation and may contribute to improving learning under normal conditions.NEW & NOTEWORTHY In this study, we were able to make a rare direct comparison of face-to-face and remote strategies for the teaching of undergraduate medical students in a specific area, namely, renal pathophysiology. Unexpectedly, students who attended the remote course had significantly higher grades than those who had mostly in-person classes.

Association between psoriasis and thyroid function: results from the Brazilian Longitudinal Study of Adults Health (ELSA-Brasil)

ABSTRACT Objective: To determine the relationship between psoriasis, thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triodothyronine (FT3), thyroid peroxidase antibodies (TPOAb), and subclinical thyroid dysfunctions in middle-aged and older adults. Materials and methods: Cross-sectional analyses included a self-reported medical diagnosis of psoriasis and thyroid function from the 3rd visit (2017-2019) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). TSH, FT4, and FT3 levels were analyzed as continuous variables and quintiles, and TPOAb positivity and subclinical hypothyroidism as a yes/no variable. Logistic regression models were built as crude and adjusted by main confounders (age, sex, education level, race/ethnicity, and smoking). Results: From 9,649 participants (52.3% women; 59.2 ± 8.7 years old), the prevalence of psoriasis was 2.8% (n = 270). TSH, FT4, TPOAb positivity, and subclinical hypothyroidism were not associated with psoriasis in the main analyses. In the stratified analysis, our findings showed positive associations of the lowest (OR = 2.01; 95% CI 1.05-3.84; p = 0.036) and the highest (OR = 2.13; 95% CI 1.12-4.05; p = 0.022) quintiles of FT4 and a protective association of TPOAb positivity (OR = 0.43; 95% CI 0.19-0.98; p = 0.046) with prevalent psoriasis in women. In the logistic regression for FT3, participants in the 1st quintile showed a statistically significant association with psoriasis for the whole sample (OR = 1.66; 95% CI 1.11-2.46; p = 0.013) and for men (OR = 2.25; 95% CI 1.25-4.04; p = 0.007) in the sex-stratified analysis. Conclusions: The present study showed that the association of FT4 levels with psoriasis are different according to sex, with a possible U-shaped curve in women but not in men. Although there were some associations of FT3 with psoriasis, they may be a consequence of non-thyroidal illness syndrome. Further prospective data may clarify the association of thyroid function and psoriasis.

Lower paraoxonase 1 paraoxonase activity is associated with a worse prognosis in patients with non-ST-segment elevation myocardial infarction in long-term follow-up.

BACKGROUND: Acute coronary syndrome (ACS) is one of the main manifestations of coronary artery disease, with a higher prevalence and worst prognosis. Oxidative stress is important in atherosclerosis and ACS, and paraoxonase 1 (PON1) is directly related to reducing the effects of oxidative stress on lipoproteins. The present study evaluated the prognostic value of PON1 activity in patients with non-ST-segment elevation ACS [non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina (UA)], included in the ERICO study. METHODS: PON1 paraoxonase activity was determined in serum samples from 485 patients collected on admission. The prognostic value in the follow-up of up to 5 years was evaluated according to cutoff points established by tertiles. Kaplan-Meier curves and Cox regression were used for the analysis of all-cause mortality and cardiovascular mortality. RESULTS: The sample consisted mainly of elderly patients with a high frequency of cardiovascular risk factors. At follow-up of up to 5 years, there were 126 deaths from all causes (80 deaths from CVD). The lowest tertile of PON1 paraoxonase activity was associated with a higher risk of death in patients with NSTEMI, but not in patients with UA. CONCLUSION: PON1 paraoxonase activity has potential prognostic value in patients with NSTEMI.

Estresse no trabalho e níveis de hemoglobina glicada: o papel da escolaridade. Dados da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) / Job stress and glycated hemoglobin levels: the role of educational attainment. Baseline data from the Longitudinal Study of Adult Health (ELSA-Brasil)

Resumo Introdução: as condições estressantes do trabalho estão associadas ao aumento dos níveis glicêmicos, mas pouco se conhece sobre o papel da escolaridade neste contexto. Objetivos: analisar a associação entre o estresse psicossocial no trabalho e os níveis de hemoglobina glicada (HbA1c) e a influência da escolaridade como modificador de efeito. Métodos: estudo transversal com dados de 11.922 trabalhadores ativos da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). O estresse psicossocial no trabalho foi avaliado pelo modelo demanda-controle. Foram empregadas a regressão logística multinomial e interações multiplicativas. Resultados: em trabalhadoras do sexo feminino com baixa escolaridade, observou-se associação entre baixo uso de habilidades no trabalho (OR 1,56; IC95% 1,09-2,24) e HbA1c elevada. A baixa autonomia no trabalho foi relacionada à HbA1c limítrofe (OR 1,21; IC95% 1,01-1,45) e elevada (OR 1,73; IC95% 1,19-2,51). Entre trabalhadores do sexo masculino com baixa escolaridade, o trabalho de alto desgaste (OR 1,94; IC95% 1,18-3,21), o baixo uso de habilidades (OR 2,00; IC95% 1,41-2,83) e a baixa autonomia no trabalho (OR 1,58; IC95% 1,13-2,21) foram associados à HbA1c elevada. Conclusão: o estresse psicossocial no trabalho foi associado a níveis limítrofes e elevados de HbAlc para trabalhadores com baixa escolaridade de ambos os sexos. Assim, ações para modificar as relações de trabalho e prevenir doenças crônicas devem ser priorizadas.

Abstract Introduction: stressful work conditions are associated to increased glycemic levels, but little is known about the role of educational attainment in this association. Objectives: to analyze the association between psychosocial stress at work, levels of glycated hemoglobin (HbA1c), and the role of educational attainment as an effect modifier. Methods: a cross-sectional study with baseline data from 11,922 active workers who participated in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Psychosocial stress at work was measured via the Demand-Control model. Multinomial logistic regression and multiplicative interactions were performed. Results: among female workers with low educational attainment, there was an association of low skill discretion and elevated HbA1c (OR 1.56; 95% CI 1.09-2.24). Low decision authority was associated to borderline (OR 1.21; 95% CI 1.01-1.45) and high (OR 1.73; 95% CI 1.19-2.51) HbA1c. Among male workers with low educational attainment, high strain (OR 1.94; 95% CI 1.18-3.21), low skill discretion (OR 2.0; 95% CI 1.41-2.83), and low decision authority (OR 1.58; 95% CI 1.13-2.21) were associated to high HbA1c. Conclusion: Stress at work was associated to high and borderline levels of HbAlc in workers from both genders with low educational attainment. Actions to modify work relations and to prevent chronic diseases should be prioritized for this group.

Hearing loss, tinnitus, and hypertension: analysis of the baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

OBJECTIVES: To investigate the association among hypertension, tinnitus, and sensorineural hearing loss and evaluate the influence of other covariates on this association. METHODS: Baseline data (2008-2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were analyzed. Altogether, 900 participants were evaluated. The baseline assessment consisted of a 7-hour examination to obtain clinical and laboratory variables. Hearing was measured using pure-tone audiometry. RESULTS: Overall, 33.3% of the participants had hypertension. Participants with hypertension were more likely to be older, male, and diabetic compared to those without hypertension. The prevalence of tinnitus was higher among hypertensive participants and the odds ratio for tinnitus was higher in participants with hypertension than in those without hypertension. However, the difference was not significant after adjusting for age. Audiometric results at 250-8,000 Hz were worse in participants with hypertension than in those without hypertension in the crude analysis; however, the differences were not significant after adjustment for age, sex, diagnosis of diabetes, and exposure to noise. No significant difference was observed in hearing thresholds among participants having hypertension for <6 years, those having hypertension for ≥6 years, and individuals without hypertension. CONCLUSION: Hearing thresholds were worse in participants with hypertension. However, after adjusting for age, sex, diagnosis of diabetes, and exposure to noise, no significant differences were observed between participants with and without hypertension. A higher prevalence of tinnitus was observed in participants with hypertension compared to those without hypertension, but without significance after adjusting for age.

"Shadow" OSCE examiner. A cross-sectional study comparing the "shadow" examiner with the original OSCE examiner format.

OBJECTIVES: Feedback is a powerful learning tool, but a lack of appropriate feedback is a very common complaint from learners to teachers. To improve opportunities for feedback on objective structured clinical examinations (OSCEs), a modified examiner role, termed the "shadow" examiner, was tested. This study aims to present and analyze comparisons between the "shadow" examiner and the original OSCE examiner format. METHODS: In 2011, experiments were carried out with modifications to the examiner's role to define the "shadow" examiner format. From February 2012 to May 2014, research was conducted with 415 6th-year medical students. Of these students, 316 were randomly assigned to assessments by both "shadow" and "fixed" examiners. Pearson correlation analysis with linear regression, Student's t-tests and Bland-Altman plots were the statistical methods used to compare the assessment modes. To strengthen the analysis, checklist items were classified by domain. RESULTS: High correlations between the "shadow" and "fixed" examiners' global scores were observed. The results of the analysis of specific domains demonstrated higher correlations for cognitive scores and lower correlations for affective scores. No statistically significant differences between the mean examiner global scores were found. The Bland-Altman analysis showed that the "shadow" examiners' affective scores were significantly higher than those of the "fixed" examiners, but the magnitude of this difference was small. CONCLUSION: The modified examiner role did not lead to any important bias in the students' scores compared with the original OSCE examiner format. This new strategy may provide important insights for formative assessments of clinical performance.

Preceptors' perception of their role as educators and professionals in a health system.

BACKGROUND: Preceptorship fulfills the requirements of International Guidelines regarding the training of health care professionals as a method of teaching in clinical settings, during the daily work routine. This study aims to analyze the preceptors' perceptions about preceptorship and their role as educators. METHODS: Data were collected via a questionnaire with 35 five-point Likert-type scale statements and analyzed using quantitative and qualitative approaches. The qualitative analysis consisted of two open-ended questions: (1) What is Preceptorship? And (2) What is your perception of the preceptor's role as an educator? RESULTS: Out of 619 invited Brazilian preceptors from different health care professions, 327 (52.8%) participated in the study. Among them, 80.7% were females, 35.2% were nurses and 8.9% were physicians. Factor analysis revealed five factors: Pedagogical Competence (F1), Support and educational resources (F2), Educational program planning (F3), Teaching-service integration (F4), and Student presence in the clinical setting (F5). About F1, F3, and F5, professionals from the northeast region had a more positive perception than professionals from the southeast. The item analysis revealed that preceptors learn from the students and consider the service network co-responsible for their training. However, they agreed that only a small part of the health care team participates in the program. Participants described preceptorship as an educational task in a clinical setting, in which active learning methods are used for the training of health care professionals. Preceptorship was considered a bridge between the Unified Health System and the Academic Practice. They envisioned their educator role as a model, tutor, leader, supervisor, and mentor. CONCLUSION: Preceptors expressed a critical view about the nature of preceptorship and their role as educators, recognizing its challenges as well as its potential in clinical settings.

Low serum levels of CCL2 are associated with worse prognosis in patients with Acute Coronary Syndrome: 2-year survival analysis.

Inflammation is very important in Acute Coronary Syndrome (ACS) as well as in cardiac remodeling after an acute myocardial infarction (MI). Our study examined the prognostic value of Chemokine (C-C motif) ligand 2 (CCL2) in patients with ACS in the ERICO (Strategy of Registry of Acute Coronary Syndrome) study. We evaluated serum samples from 803 patients. The prognostic value of CCL2 was evaluated at the 2-year follow-up, according to cutoff points established by the median. Kaplan-Meier curves and Cox regression were used for analysis of all-cause mortality, cardiovascular mortality, and a combined outcome of fatal myocardial infarction or new non-fatal MI. There were 115 deaths from all causes, 78 deaths due to cardiovascular causes and 67 events in combined outcomes. CCL2 levels below the median (≤100.9 pg/mL) were associated with increased risk of MI death or new non-fatal MI, even after model adjustment. Low serum levels of CCL2 shows a significant association with fatal or new non-fatal MI.

Lack of Association Between Subclinical Hypothyroidism and Carotid-Femoral Pulse Wave Velocity in a Cross-Sectional Analysis of the ELSA-Brasil.

BACKGROUND: There is little available data on carotid-femoral pulse wave velocity (cf-PWV) in subjects with subclinical hypothyroidism (SCH). We aimed to analyze the association between SCH and cf-PWV using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS: We included subjects with normal thyroid function (thyrotropin (TSH): 0.4-4.0 mIU/l, and normal free thyroxine (FT4: 0.8-1.9ng/dl) and SCH (TSH > 4.0 mIU/l and normal FT4) evaluated for cf-PWV in a cross-sectional analysis. We excluded individuals using medications that interfere in thyroid function, antihypertensives, or diuretics, and subjects with chronic kidney disease or previous cardiovascular disease. Generalized linear and logistic regression models evaluated cf-PWV as a dependent variable and SCH as an independent variable, adjusted for cardiovascular risk factors. RESULTS: Of 8,341 subjects (52.3% women), 7,878 (94.4%) were euthyroid and 463 (5.6%) showed SCH. The median age was 50 years (interquartile range: 44-56). The groups differed by age, sex, body mass index, glomerular filtration rate, and C-reactive protein. SCH was not associated with cf-PWV in the full-adjusted linear model (ß = -0.039; P = 0.562) and with cf-PWV >75th percentile in the full-adjusted logistic model (odds ratio = 0.94; 95% confidence interval = 0.72-1.22). CONCLUSION: In a large sample, SCH was not associated with increased cf-PWV.

Avaliação da presença e extensão dos atributos de atenção primária em dois modelos coexistentes na rede básica de saúde do Município de São Paulo / Assessment of the presence and extent of primary care attributes in two coexisting models of the primary health care network of the city of São Paulo / Evaluación de la presencia y extensión de los atributos de atención primaria de salud en dos modelos coexistentes en la red básica de salud de la ciudad de São Paulo

Introdução: No Brasil, faltam avaliações que mensurem o desempenho direto da Atenção Primária à Saúde (APS). Serviços desenvolvidos para a atenção à demanda espontânea de baixa complexidade como as Assistências Médicas Ambulatoriais (AMA), de São Paulo, são oferecidos como alternativa à Estratégia de Saúde da Família (ESF), o serviço brasileiro oficial de APS, mas ainda não há estudos comparativos entre eles. Objetivo: Comparar a presença e extensão dos atributos de APS em dois representantes desses dois serviços da cidade de São Paulo: uma Unidade Básica de Saúde (UBS), parte integrante da ESF, e uma AMA. Métodos: Este artigo trata de um estudo transversal utilizando o Primary Care Assessment Tool, versão validada em português (PCATool Brasil). Resultados: Foram aplicados 616 questionários, 76,3% demonstrou-se afiliado à UBS e 12,3% à AMA. Os frequentadores da UBS se demonstraram mais pobres. A UBS apresentou escores essencial e geral maiores (5,64 e 5,58 contra 3,70 e 3,38, respectivamente) e teve médias superiores em todos os atributos, exceto "acessibilidade" (2,46 contra 3,68). Apenas a UBS apresentou atributos com escores superiores a 6,6: "Acesso de Primeiro Contato - Utilização" (7,22) e "Coordenação - Sistemas de Informação" (7,31). Entretanto, a má avaliação dos outros atributos do PCATool na UBS foi preponderante para considerá-la um serviço de baixa orientação à APS, assim como a AMA. Conclusão: Os usuários identificam muito pouco os atributos de APS nos dois serviços, em um nível aquém do considerado satisfatório, mesmo que os escores da UBS sejam mais elevados do que os da AMA em 8 dos 10 atributos. Apesar de ser reconhecido como um bom local para realizar o primeiro contato com o sistema, a falta de acessibilidade prejudica a UBS como serviço de APS. A AMA, apresentada como a solução para o problema, não demonstra desempenho que a justifique como alternativa.

Introduction: In Brazil, there is a lack of information about the direct performance of Primary Health Care. In the city of São Paulo, Outpatient Medical Care units (Assistências Médicas Ambulatoriais - AMAs), walk-in clinics developed to address acute diseases of low complexity, are offered as an alternative to the Family Health Strategy - FHS (Estratégia Saúde da Família), the official Brazilian PHC service, and there are no comparative studies of them. Objectives: To assess the presence and extent of PHC attributes in two units in the city of São Paulo: a Basic Health Unit (Unidade Básica de Saúde - BHU), part of the FHS, and an AMA. Methods: This article is a cross-sectional study using the Primary Care Assessment Tool validated version in Portuguese (PCATool Brazil). Results: Questionnaires were applied to 616 people, 76.3% of whom reported an affiliation with the BHU and 12.3% with the AMA. The BHU users were poorer. The BHU had higher essential and overall scores than the AMA (5.64 and 5.58 versus 3.70 and 3.38, respectively) and higher averages for all the attributes, except for "accessibility" (2.46 compared to 3.68. Only the BHU presented scores over 6.6: "Access to First Contact - Utilization" (7.22) and "Coordination - Systems of Information" (7.31). However, the poor evaluation of the other PCATool attributes in the BHU was preponderant to consider it as a low oriented PHC service, just as the AMA. Conclusion: The users identified a very low level of satisfactory development of PHC attributes in the two services evaluated, even though the BHU scores were higher than those of the AMA in 8 of the 10 attributes. Despite being recognized as a good place to get the first contact to the system, the lack of accessibility affects BHU as a PHC service. The AMA, presented as the solution to the problem, has no performance to justify itself as an alternative.

Resultados: Se aplicaron 616 cuestionarios, 76,3% resultó estar afiliado a UBS y 12,3% a la AMA. Los clientes de la UBS se demostraron más pobres. UBS tuve puntuaciones superiores en los escores esenciales y generales (5,64 y 5,58 frente a 3,70 y 3,38) y tuvieron promedios más altos en todos los atributos excepto la "accesibilidad" (2,46 frente a 3,68). Sólo UBS presentó atributos con puntuaciones más altas que 6,6: "Acceso de Primer Contacto - Utilización" (7,22) y "Coordinación - Sistemas de Información" (7,31). Sin embargo, la mala evaluación de los otros atributos del PCATool en la UBS fue preponderante para considerarla como un servicio de baja orientación a la APS, así como la AMA. Conclusión: Los usuarios identificaron muy poco los atributos de APS en ambos los servicios a un nivel abajo de lo satisfactorio, aunque los resultados de UBS fueron superiores a la AMA en 8 de los 10 atributos. A pesar de ser reconocido como un buen lugar para lograr el primer contacto con el sistema, la falta de accesibilidad afecta la UBS como servicio de APS. La AMA, presentada como la solución al problema, no tiene el rendimiento para justificarla como una alternativa.

Medical Students' Perception of Their Educational Environment and Quality of Life: Is There a Positive Association?

PURPOSE: To assess perceptions of educational environment of students from 22 Brazilian medical schools and to study the association between these perceptions and quality of life (QoL) measures. METHOD: The authors performed a multicenter study (August 2011 to August 2012), examining students' views both of (1) educational environment using the Dundee Ready Education Environment Measure (DREEM) and (2) QoL using the World Health Organization Quality of Life Assessment, abbreviated version (WHOQOL-BREF). They also examined students' self-assessment of their overall QoL and medical-school-related QoL (MSQoL). The authors classified participants' perceptions into four quartiles according to DREEM total score, overall QoL, and MSQoL. RESULTS: Of 1,650 randomly selected students, 1,350 (81.8%) completed the study. The mean total DREEM score was 119.4 (standard deviation = 27.1). Higher total DREEM scores were associated with higher overall QoL and MSQoL scores (P < .001 for all comparisons) and younger ages (P < .001). Mean overall QoL scores were higher than MSQoL scores (mean difference, 1.35; 95% confidence interval [CI] 1.28-1.43; P < .001). Multinomial regression models showed significant dose-response patterns: Higher DREEM quartile scores were associated with better QoL. The psychological health domain of WHOQOL-BREF was most closely associated with DREEM scores (odds ratio 4.70; 95% CI = 3.80-5.81). CONCLUSIONS: The authors observed a positive association between QoL measures and DREEM scores. This association had a dose-response effect, independent of age, sex, and year of medical training, showing that educational environment appears to be an important moderator of medical student QoL.

One-year Mortality after an Acute Coronary Event and its Clinical Predictors: The ERICO Study / Mortalidade em um Ano após Evento Coronário Agudo e seus Preditores Clínicos: O estudo ERICO

Information about post-acute coronary syndrome (ACS) survival have been mostly short-term findings or based on specialized, cardiology referral centers.

Diagnostic accuracy of a noninvasive hepatic ultrasound score for non-alcoholic fatty liver disease (NAFLD) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

CONTEXT AND OBJECTIVE: Noninvasive strategies for evaluating non-alcoholic fatty liver disease (NAFLD) have been investigated over the last few decades. Our aim was to evaluate the diagnostic accuracy of a new hepatic ultrasound score for NAFLD in the ELSA-Brasil study. DESIGN AND SETTINGS: Diagnostic accuracy study conducted in the ELSA center, in the hospital of a public university. METHODS: Among the 15,105 participants of the ELSA study who were evaluated for NAFLD, 195 individuals were included in this sub-study. Hepatic ultrasound was performed (deep beam attenuation, hepatorenal index and anteroposterior diameter of the right hepatic lobe) and compared with the hepatic steatosis findings from 64-channel high-resolution computed tomography (CT). We also evaluated two clinical indices relating to NAFLD: the fatty liver index (FLI) and the hepatic steatosis index (HSI). RESULTS: Among the 195 participants, the NAFLD frequency was 34.4%. High body mass index, high waist circumference, diabetes and hypertriglyceridemia were associated with high hepatic attenuation and large anteroposterior diameter of the right hepatic lobe, but not with the hepatorenal index. The hepatic ultrasound score, based on hepatic attenuation and the anteroposterior diameter of the right hepatic lobe, presented the best performance for NAFLD screening at the cutoff point ≥ 1 point; sensitivity: 85.1%; specificity: 73.4%; accuracy: 79.3%; and area under the curve (AUC 0.85; 95% confidence interval, CI: 0.78-0.91)]. FLI and HSI presented lower performance (AUC 0.76; 95% CI: 0.69-0.83) than CT. CONCLUSION: The hepatic ultrasound score based on hepatic attenuation and the anteroposterior diameter of the right hepatic lobe has good reproducibility and accuracy for NAFLD screening.

One-year Mortality after an Acute Coronary Event and its Clinical Predictors: The ERICO Study.

BACKGROUND: Information about post-acute coronary syndrome (ACS) survival have been mostly short-term findings or based on specialized, cardiology referral centers. OBJECTIVES: To describe one-year case-fatality rates in the Strategy of Registry of Acute Coronary Syndrome (ERICO) cohort, and to study baseline characteristics as predictors. METHODS: We analyzed data from 964 ERICO participants enrolled from February 2009 to December 2012. We assessed vital status by telephone contact and official death certificate searches. The cause of death was determined according to the official death certificates. We used log-rank tests to compare the probabilities of survival across subgroups. We built crude and adjusted (for age, sex and ACS subtype) Cox regression models to study if the ACS subtype or baseline characteristics were independent predictors of all-cause or cardiovascular mortality. RESULTS: We identified 110 deaths in the cohort (case-fatality rate, 12.0%). Age [Hazard ratio (HR) = 2.04 per 10 year increase; 95% confidence interval (95%CI) = 1.75­2.38], non-ST elevation myocardial infarction (HR = 3.82 ; 95%CI = 2.21­6.60) or ST elevation myocardial infarction (HR = 2.59; 95%CI = 1.38­4.89) diagnoses, and diabetes (HR = 1.78; 95%CI = 1.20­2.63) were significant risk factors for all-cause mortality in the adjusted models. We found similar results for cardiovascular mortality. A previous coronary artery disease diagnosis was also an independent predictor of all-cause mortality (HR = 1.61; 95%CI = 1.04­2.50), but not for cardiovascular mortality. CONCLUSION: We found an overall one-year mortality rate of 12.0% in a sample of post-ACS patients in a community, non-specialized hospital in São Paulo, Brazil. Age, ACS subtype, and diabetes were independent predictors of poor one­year survival for overall and cardiovascular-related causes.

Diagnostic accuracy of a noninvasive hepatic ultrasound score for non-alcoholic fatty liver disease (NAFLD) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) / Acurácia diagnóstica de um escore de ultrassonografia hepática não invasivo para doença hepática gordurosa não alcoólica (DHGNA) no Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil)

CONTEXT AND OBJECTIVE: Noninvasive strategies for evaluating non-alcoholic fatty liver disease (NAFLD) have been investigated over the last few decades. Our aim was to evaluate the diagnostic accuracy of a new hepatic ultrasound score for NAFLD in the ELSA-Brasil study. DESIGN AND SETTINGS: Diagnostic accuracy study conducted in the ELSA center, in the hospital of a public university. METHODS: Among the 15,105 participants of the ELSA study who were evaluated for NAFLD, 195 individuals were included in this sub-study. Hepatic ultrasound was performed (deep beam attenuation, hepatorenal index and anteroposterior diameter of the right hepatic lobe) and compared with the hepatic steatosis findings from 64-channel high-resolution computed tomography (CT). We also evaluated two clinical indices relating to NAFLD: the fatty liver index (FLI) and the hepatic steatosis index (HSI). RESULTS: Among the 195 participants, the NAFLD frequency was 34.4%. High body mass index, high waist circumference, diabetes and hypertriglyceridemia were associated with high hepatic attenuation and large anteroposterior diameter of the right hepatic lobe, but not with the hepatorenal index. The hepatic ultrasound score, based on hepatic attenuation and the anteroposterior diameter of the right hepatic lobe, presented the best performance for NAFLD screening at the cutoff point ≥ 1 point; sensitivity: 85.1%; specificity: 73.4%; accuracy: 79.3%; and area under the curve (AUC 0.85; 95% confidence interval, CI: 0.78-0.91)]. FLI and HSI presented lower performance (AUC 0.76; 95% CI: 0.69-0.83) than CT. CONCLUSION: The hepatic ultrasound score based on hepatic attenuation and the anteroposterior diameter of the right hepatic lobe has good reproducibility and accuracy for NAFLD screening. .

CONTEXTO E OBJETIVO: Estratégias não invasivas para avaliar doença hepática gordurosa não alcoólica (DHGNA) têm sido investigadas nas últimas décadas. Nosso objetivo foi avaliar a acurácia diagnóstica de um novo escore de ultrassonografia hepática para DHGNA no estudo ELSA-Brasil. TIPO DE ESTUDO E LOCAL: Estudo de acurácia diagnóstica realizado no centro ELSA, no hospital de uma universidade pública. MÉTODOS: Dos 15.105 participantes do estudo ELSA avaliados para DHGNA, 195 indivíduos foram incluídos neste estudo. Foi realizada ultrassonografia hepática (atenuação do feixe de profundidade, índice hepatorrenal e diâmetro anteroposterior do lobo direito do fígado) que foi comparada aos achados de esteatose hepática da tomografia computadorizada (TC) de alta resolução de 64 canais. Avaliamos também dois índices clínicos relacionados à DHGNA: o índice de gordura hepática (FLI) e o índice de esteatose hepática (HSI). RESULTADOS: Entre os 195 participantes, a frequência de DHGNA foi de 34,4%. Altos índices de massa corpórea, circunferência de cintura, diabetes e hipertrigliceridemia foram associados a aumento da atenuação hepática e do diâmetro anteroposterior do lobo hepático direito, mas não ao índice hepato-renal. A pontuação da ultrassonografia hepática, que incluiu atenuação hepática e diâmetro anteroposterior do lobo direito do fígado, apresentou o melhor desempenho para o rastreio DHGNA sob o ponto de corte ≥ 1 ponto (sensibilidade: 85.1%; especificidade: 73.4%; acurácia: 79.3%), e área sob a curva (AUC, 0,85, IC 95%: 0,78-0,91). FLI e HSI apresentaram menor desempenho (AUC 0,76; IC 95%: 0,69-0,83) comparados à TC. CONCLUSÃO: O escore de ultrassonografia hepática, que incluiu atenuação hepática e o diâmetro anteroposterior do lobo direito do fígado, possui boa reprodutibilidade e acurácia para o rastreio de DHGNA. .

Stroke in the rain forest: prevalence in a ribeirinha community and an urban population in the Brazilian Amazon.

BACKGROUND: Our objective was to determine the cerebrovascular prevalence in a town in the Brazilian Amazon basin and compare the ribeirinhos (riparians) to the urban population in the same municipality. METHODS: From May to October 2011, 6,216 residents over 35 years of age in the town of Coari were interviewed using a screening questionnaire, the Stroke Symptom Questionnaire. Cerebrovascular prevalence rates (PRs) from the door-to-door surveillance were calculated according to the location of the home. RESULTS: Respondent totals were 4,897 in the urban area and 1,028 in the rural area. The crude prevalence of stroke was 6.3% in rural and 3.7% in urban areas with differences maintained after sex and age adjustment. Among stroke cases, the ribeirinhos were those with less access to medical care in comparison to the urban area (32.1 vs. 52.5%, p = 0.01), and a positive association between rural area and no medical care for stroke remained (PR, 1.33; 95% confidence interval, 1.03-1.71), independently of age, sex, education and functional impairment. CONCLUSIONS: This study provides the first population-based cerebrovascular prevalence comparison between an urban and a rural population in the Amazon rain forest. The PRs were higher in the ribeirinha compared to the urban population in the same municipality.
