Abstract Background: Hospital accreditation has as goal the standardization of patient care, aiming quality improvement. On 2015, a cardiology reference hospital was evaluated and got level 3 from ONA in care given to Acute Coronary Syndrome (ACS) patients. Objetive: To compare length of stay (LOS) at Coronary Care Unit (CCU) and the total LOS at the hospital of ACS patients before and after ONA 3 accreditation. Other clinical outcomes were also analyzed. Methods: Systematic and prospective registry of admitted ACS patients at CCU, whose population was divided into pre-accreditation (period 1) and post-accreditation (period 2). Descriptive analysis was performed. For statistical analysis the Mann-Whitney test, chi-squared, Fisher’s exact test and Multiple Linear Regression were performed. P value was considered statistically significant when < 0,05. Results: 372 patients were admitted with ACS, 186 in period 1, of which 47 (25,3%) with ST segment Elevation Myocardial Infarction (STEMI), and 186 in period 2, of which 70 (37,6%) with STEMI. The mean age was 65,9 years (± 12,2). About the CCU LOS, there was a reduction from 3 (IQR: 2-4) to 2,5 days (IQR: 2-4; p value = 0,088). Regarding the hospital LOS, there was also a reduction from 8 (IQR: 5-12,25) to 6 days (IQR:4-11; p value = 0,004). Analyzing the type of ACS, there was a significant reduction only at the hospital LOS in non-STEMI patients: 8 to 6 days (p value = 0,001). Other hospitalization length of stay and clinical outcomes did not present a significant reduction in the comparison. Conclusion: After the ONA 3 accreditation, there was a reduction of hospital LOS. There were no significant differences in the other outcomes analyzed.

OBJETIVO: Investigar a associação entre níveis elevados de adiponectina plasmática (AdipoQ) e baixo risco cardiometabólico (RCM) em obesas (MOb). SUJEITOS E MÉTODOS: Estudo caso-controle, pareado pela idade com 306 MOb, IMC > 30 kg/m², sendo 66 (21,6%) casos - todos não hipertensos, normolipídicos e não diabéticos - realizados em ambulatórios referência do Sistema Único de Saúde (SUS) para obesidade em Salvador. Dados secundários foram coleta-dos dos prontuários médicos, primários e complementares em laboratório de patologia clínica. Valores de AdipoQ > 10,00 µg/mL (> 3º quartil) foram considerados elevados. Foram realizadas análises: descritiva, bivariada e regressão logística condicional. RESULTADOS: Associação positiva, estatisticamente significante (ES), entre baixo RCM e AdipoQ > 10,00 µg/mL em MOb ativas fisicamente (OR= 5,1; IC95%: 1,8-14,3), não fumantes (OR= 3,6; IC95%: 1,6-8,4). CONCLUSÃO: Este estudo sugere que MOb ativas fisicamente, não fumantes e com níveis mais elevados de AdipoQ apresentam mais chances de baixo RCM. Torna-se importante reforçar, por meio de políticas públicas, o estímulo à adoção de comportamentos saudáveis.

OBJECTIVE: To investigate the association between elevated levels of plasmatic adiponectin (AdipoQ) and low cardiometabolic risk (CMR) in obese women (ObW). SUBJECTS AND METHODS: Case-control study, matched by age, of 306 ObW, BMI > 30 kg/m², with 66 cases (21.6%) - all non-hypertensive, normolipidemic, and non-diabetic - conducted in SUS (Brazil's Public Health System) outpatient referral services for obesity in the City of Salvador, Brazil. Secondary data were collected from medical records; primary and complementary data were obtained from a clinical pathology laboratory. Values of AdipoQ > 10.00 µg/ml (> 3rd quartile) were considered elevated. Descriptive, bivariate, and conditional logistic regression analyses were performed. RESULTS: A statistically significant positive association between low CMR and AdipoQ > 10.00 µg/ml in physically active (AOR = 5.1; CI95%: 1.8-14.3), non-smoking (AOR = 3.6;CI95%: 1.6-8.4) ObW was found. CONCLUSION: This study suggests that physically active, non-smoking ObW, with higher AdipoQ levels, present greater chances of a low CMR. It becomes important to reinforce encouragement of the adoption of healthy behaviors, by means of public policies.

FUNDAMENTO: A síndrome metabólica tem uma elevada prevalência em diferentes partes do mundo, com variações entre diferentes grupos étnicos. OBJETIVO: Este estudo pretende explorar a influência da cor de pele auto-referida sobre a prevalência da SM. MÉTODOS: Estudo transversal, realizado em subgrupo populacional em Salvador, Brasil. Utilizou-se auto-definição de cor de pele (branca, parda e negra) e o critério de SM do ATP-III. Foi usado o quiquadrado para tendência a fim de analisar gradiente das prevalências entre os grupos e a regressão logística para análises de associações. RESULTADOS: A prevalência geral da SM, ajustada por variáveis potencialmente confundidoras, não diferiu entre brancos (23,3%), pardos (23,3%) e negros (23,4%,). A análise por sexo mostrou entre os homens redução da prevalência da SM dos brancos, 26,2% IC95%(20,7-31,7), em comparação aos negros, 17,5% IC95% (12,3-22,8), e uma prevalência intermediária entre os pardos, 21,9% IC95% (18,6 - 25,1), p tend= 0,002. Entre as mulheres, a tendência foi inversa, maior nas negras, 27,0% IC95% (22,2-31,8), e menor nas brancas, 20,5% IC95%(15,6-25,4), p tend= 0,02. Na análise multivariada da associação entre cor de pele e SM (branco=grupo de referência), a cor negra entre os homens foi fator de proteção, razão de prevalência (RP)= 0,60 (0,36 - 0,97), enquanto que nas mulheres tendeu a ser fator de risco, RP= 1,33 (0,94 - 1,78). CONCLUSÃO: A prevalência da SM variou em função da cor de pele de modo inverso entre homens e mulheres. Ser negro foi fator de proteção entre homens e de risco nas mulheres.

BACKGROUND: The metabolic syndrome (MS) has a high prevalence in different parts of the world, with variations between different ethnic groups. OBJECTIVE: This study aims at exploring the influence of the self-reported skin color on the prevalence of MS Methods: Cross-sectional study, carried out in a population subgroup (n=1,439 adults) in Salvador, Brazil. The self-reported skin color (white, mulatto or black) was used as well as the MS criterion of ATP-III. The Chi-square test for tendency was used to analyze the prevalence gradient between the groups and logistic regression, for association analysis. RESULTS: The general prevalence of MS, adjusted for potentially confounder variables, did not differ among whites (23.3%), mulattos (23.3%) and blacks (23.4%). The analysis by sex showed, among men, a reduction in the MS prevalence of whites (26.2%, 95%CI: 20.7-31.7), in comparison to blacks (17.5%, 95%CI: 12.3-22.8) and an intermediate prevalence among mulattos, 21.9%, 95%CI: 18.6-25.1, p tend. = 0.002. Among the women, the tendency was the opposite, being higher among the blacks, 27.0%, 95%CI: 22.2-31.8, and lower among the whites, 20.5%, 95%CI: 15.6-25.4, p tend. = 0.02. The multivariate analysis of the association between skin color and MS (white = group of reference) showed that the black color of the skin was a protective factor among black men, with a prevalence ratio (PR) = 0.60 (0.36-0.97), whereas it tended to be a risk factor among black women, with a PR = 1.33 (0.94-1.78). CONCLUSION: The prevalence of MA presented an inverse variation according to the color of skin between men and women. To be black was a protective factor among men and a risk factor among women.

OBJETIVO: Analisar a quantidade (intensidade e duração) de atividade física total e em seus diferentes domínios (trabalho, deslocamento, atividade doméstica e tempo livre) como preditores da ausência de diabetes em população de etnia negra. MÉTODOS: Estudo transversal com amostra de 2305 adultos negros de 20 anos a 96 anos de idade, sendo 902 (39,1%) homens, residentes na cidade de Salvador, Bahia, Brasil. Foram construídas curvas Receiver Operating Characteristic (ROC) e comparadas às áreas entre a quantidade de atividade física em seus diferentes domínios e a ausência de diabetes. Verificou-se também a sensibilidade e especificidade para identificar os melhores pontos de corte da quantidade de atividade física para a ausência de diabetes. Com base nestes pontos de corte, construiu-se modelo multivariado para identificar associação entre atividade física e diabetes. RESULTADOS: Entre as diferentes quantidades de atividade física encontrou-se maior significância estatística nas áreas sob a curva ROC na atividade física total, nas atividades moderadas realizados no tempo livre e no trabalho entre os homens, e no deslocamento entre as mulheres. A caminhada isoladamente não foi bom preditor da ausência de diabetes entre homens. Observou-se também que 185 minutos/semana de atividade física acumulada nos diferentes domínios para homens e 215 minutos/semana para mulheres foram os melhores pontos de corte para predizer a ausência de diabetes, porém após análise multivariada encontrou-se associação entre atividade física e diabetes apenas entre os homens. CONCLUSÃO: A atividade física acumulada nos diferentes domínios deve ser sugerida em quantidades adequadas para a população de etnia negra visando contribuir para a prevenção do diabetes.

OBJECTIVE: Analyze how much total physical activity (intensity and duration) is required and its different domains (work, commuting, household, and leisure time) as predictors of absence of diabetes in the black ethnicity population. METHODS: The design was cross-sectional with a sample of 2305 adults from 20 to 96 years of age, 902 (39.1%) male, living in the city of Salvador, Brazil. Receiver Operating Characteristic curves (ROC) were constructed to compare the areas of amount of physical activity in their different domains with absence of diabetes. Sensitivity and specificity were also established to identify the best cutoffs for the amount of physical activity related to absence of diabetes. Based on these cutoff points, a multivariate model was constructed to identify the association between physical activity and diabetes. RESULTS: Among the different amounts of physical activity greater significance was found in areas under the ROC curve for total physical activity, moderate activities performed during leisure time and work among men and commuting among women. Walking by itself was not a good predictor of absence of diabetes among men. It was also observed that 185 minutes/week of physical activity accumulated in different domains for men and 215 minutes/week for women were the best cutoffs for predicting absence of diabetes. CONCLUSION: Physical activity accumulated in different domains should be suggested in amounts suitable for a black ethnicity population in order to contribute to diabetes prevention.

OBJETIVO: Identificar e propor os melhores pontos de corte da circunferência da cintura (CCp) para diagnosticar obesidade central numa população brasileira; compará-los àqueles recomendados pelo ATPIII (CC-ATPIII) e estimar diferenças nas prevalências da síndrome metabólica (SM) usando os dois critérios. MÉTODOS: Estudo transversal, realizado em subgrupo populacional de 1.439 adultos, Salvador, Brasil. Foram construídas curvas ROC da circunferência da cintura (CC) para identificar diabete melito (DM) e obesidade. Valores >60% da sensibilidade e da especificidade da curva ROC e mais próximos entre si foram usados para definir o CCp. A prevalência da SM foi estimada pelos CCp e pelos CC-ATPIII. RESULTADOS: As 829 mulheres compuseram 57,7% da amostra. Os CCp selecionados foram 84 cm para mulheres e 88 cm para homens. Esses pontos detectaram DM com sensibilidade de 68,7% e 70%, respectivamente, e especificidade de 66,2% e 68,3%. Para obesidade, a sensibilidade e a especificidade foram 79,8% e 77,6% nas mulheres, e 64,3% e 71,6% nos homens. Pelos CC-ATPIII, 88 cm (mulheres) e 102 para (homens), as sensibilidades foram de 53,3% e 26,5%, para diagnosticar DM. Para obesidade, a sensibilidade foi 66,5% (mulheres) e 28,6% (homens). A prevalência da SM, pelos CCp foi 23,7%, IC 95% (21,6 - 25,9) e pelos CC-ATPIII de 19,0%, IC 95% (17,1- 20,9), 1,2 vezes maior pelo CCP. CONCLUSÃO: As CC-ATPIII foram inapropriados e subestimam a prevalência da SM nessa população, particularmente entre os homens. Sugerimos que os pontos de corte da CC de >84 cm nas mulheres e > 88 cm nos homens sejam testados em outras populações brasileiras.

OBJECTIVE: To identify and propose the optimal waist circumference cut-off points (WCp) for the diagnosis of central obesity (CO) in a Brazilian population, so as to compare these cut-off points with those recommended by the ATPIII (WC-ATPIII), and to estimate the difference in prevalence rates of metabolic syndrome (MS) using the two criteria. METHODS: Cross-sectional study conducted in a population subgroup of 1439 adults in the city of Salvador, Brazil. ROC curves of waist circumference (WC) were plotted to identify diabetes mellitus (DM) and obesity. ROC curve sensitivity and specificity values >60% and the closest to each other were used to define WCp. The prevalence of MS was estimated using WCp and WC-ATPIII. RESULTS: Eight hundred and twenty nine women comprised 57.7% of the sample. The WCp selected were 84cm for women and 88cm for men. These cut-off points detected DM with a 68.7% and 70% sensitivity, and a 66.2% and 68.3% specificity, respectively. For obesity, sensitivity and specificity were 79.8% and 77.6% in women and 64.3% and 71.6% in men, respectively. Using WC-ATPIII, 88cm (for women) and 102cm (for men), the sensitivity was 53.3% and 26.5%, respectively, to diagnose DM. For obesity, sensitivity was 66.5% (for women) and 28.6% (for men). The prevalence of MS using WCp was 23.7%, 95%CI (21.6 - 25.9), whereas using WC-ATPIII it was 19.0%, 95%CI (17.1- 20.9), 1.2 times higher using WCp. CONCLUSION: WC-ATPIII were inappropriate and underestimated the prevalence of MS in the population studied, particularly among men. We suggest that the WC cut-off points > 84cm for women and > 88cm for men should be tested in other Brazilian populations.

OBJECTIVE: To identifity characteristics associated with complications during pregnancy and puerperium in patients with rheumatic mitral stenosis. METHODS: Forty-one pregnant women (forty-five pregnancies) with mitral stenosis, followed-up from 1991 to 1999 were retrospectively evaluated. Predictor variables: the mitral valve area (MVA), measured by echocardiogram, and functional class (FC) before pregnancy (NYHA criteria).Maternal events: progression of heart failure, need for cardiac surgery or balloon mitral valvulotomy, death, and thromboembolism. Fetal/neonatal events: abortion, fetal or neonatal death, prematurity or low birth weight (<2,500g), and extended stay in the nursery or hospitalization in newborn ICU. RESULTS: The mean ± SD of age of the patients was 28.8±4.6 years. The eventful and uneventful patients were similar in age and percentage of first pregnancies. As compared with the level 1 MVA, the relative risk (RR) of maternal events was 5.5 (95% confidence interval (CI) =0.8-39.7) for level 2 MVA and 11.4 (95% CI=1.7-74.5) for level 3 MVA. The prepregnancy FC (FC > or = II and III versus I) was also associated with a risk for maternal events (RR=2.7; 95% CI=1.4-5.3).MVA and FC were not importantly associated with these events, although a smaller frequency of fetal/neonatal events was observed in patients who had undergone balloon valvulotomy. CONCLUSION: In pregnant women with mitral stenosis, the MVA and the FC are strongly associated with maternal complications but are not associated with fetal/neonatal events. Balloon mitral valvulotomy could have contributed to reducing the risks of fetal/neonatal events in the more symptomatic patients who had to undergo this procedure during pregnancy.
