Persistent organic pollutants distribution in plasma lipoprotein fractions / Distribuição persistente de poluentes orgânicos em frações de lipoproteínas plasmáticas

This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.

Este estudo determina as associações entre o perfil lipídico sérico, o risco de doença cardiovascular e os poluentes orgânicos persistentes. Por meio da técnica de cromatografia gasosa, mediu-se a intensidade dos resíduos de poluentes tóxicos em amostras de soro de pacientes hipertensos. Com base na análise estatística, os efeitos de diferentes covariáveis – ou seja, pesticidas, idade, pressão arterial sistólica, pressão arterial diastólica e duração do perfil lipídico – foram verificados usando o modelo de regressão logística. O cálculo estatístico foi realizado no SPSS 22.0. Os valores P da estatística F para cada classe de perfil lipídico são maiores que 0,01 (1%), portanto não podemos rejeitar a hipótese nula para todos os casos. Os coeficientes estimados, seus erros padrão, estatística de Wald e odds ratio do modelo de regressão logística binária para diferentes parâmetros do perfil lipídico indicam se os pesticidas aumentam, então o valor logit de diferentes parâmetros do perfil lipídico muda de -0,46 para -0,246, exceto LDL, que aumenta em 0,135. O estudo relata um aumento significativo da ameaça de doença cardiovascular com aumento das concentrações de poluentes tóxicos.

Depression and Cardiovascular Disease in Women

Abstract The prevalence of depression varies from 1 to 17% in different geographic regions, and its incidence is 70% higher in women than men. Today, depression affects more than 300 million people worldwide, affecting twice as many women from adolescence to adulthood. In addition to this earlier onset, depression in women tends to be more severe. Cardiovascular disease and depression are chronic diseases that have a major impact on cardiovascular and all-cause morbidity and mortality, with evidence of a two-way relationship between them, in which depression is a predictor of cardiovascular disease and vice versa. In females, the degree of illness and prognosis are more severe when both diseases are present, than when diagnosed alone. In patients with acute or chronic cardiovascular disease, especially women, a systematic screening for depression should be considered as a preventive strategy of cardiovascular events, aiming to reduce the risk of future events. There are still no clinical studies designed to assess the impact of antidepressant treatment on cardiovascular outcomes in women.

Periodontitis and its associated factors in patients at the faculty of southern Brazil: a cross - sectional study

To verify the presence of periodontitis, its severity, and their association with associated factors based on medical records of patients who attended the Dental Clinic of the Faculty of Southern Brazil over 4 years. This is a cross-sectional study, which included 422 medical records of patients aged ≥ 18 years. The clinically analyzed data were: plaque index (PI),bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). Sociodemographic data, dental hygiene, harmful habits and chronic systemic diseases were described. Statistical analysis of binary logistic regression was used to verify the relationship between the severity of periodontitis and the exposure variables. The older adults [odds ratio (OR) = 2.36; 95% confidence interval (CI): 1.23-4.54 ­41 to 55 years and OR = 3.0; 95% CI: 1.49-6.09 ­56 to 87 years], and men (OR = 1.9; 95% CI: 1.18-3.14) showed higher chances of periodontitis severity. Smokers (OR = 3.54; 95% CI: 2.05-6.12), those with hypertension (OR = 2.11; 95% CI: 1.23-3.63) and with diabetes (OR = 2.10; 95% CI: 1.08-4.12) showed higher chances of developing advanced periodontitis. Advanced or severe periodontitis occurred in one-third of the patients. The findings showed that men, older adults, with systemic arterial hypertension, diabetes mellitus, and smokers are more susceptible to severe periodontitis.

Linear and Nonlinear Heart Rate Variability Analysis in Gonadal Dysgenesis (Swyer Syndrome): A Case Report

Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis while at rest. This research analyzed linear and nonlinear indexes. HRV analysis showed reduced parasympathetic and global modulation with an apparent increase in sympathetic tone and a loss of HR fractal dynamics toward correlated behavior, characterized by low entropy and high determinism of time series.

Prevalencia de enfermedad arterial oclusiva crónica de extremidades inferiores en pacientes de alto riesgo cardiovascular pertenecientes a un centro de atención primaria mediante el uso del índice tobillo-brazo / Prevalence of peripheral arterial disease of lower extremities in high cardiovascular risk patients from primary care using the ankle-brachial index

Resumen Objetivo: La enfermedad arterial oclusiva crónica de extremidades inferiores (EAOC EEII) ha sido subestimada y subdiagnosticada especialmente a nivel de atención primaria. El objetivo de este estudio fue estimar la prevalencia de EAOC EEII en pacientes de alto riesgo cardiovascular pertenecientes a un centro de salud familiar. Materiales y Método: Estudio observacional de corte transversal. Se calculó un tamaño muestral de 246 pacientes, con una potencia estadística del 80% y un nivel de confianza del 95%, seleccionándolos aleatoriamente de 1.361 pacientes con riesgo cardiovascular alto del CESFAM Cordillera Andina, a quienes se les realizó la medición del índice tobillobrazo (ITB). Se estimaron IC 95% para cada media y porcentaje reportado, considerándose un valor de p significativo menor de 0,05 en las pruebas estadísticas utilizadas. Resultados: Se observó un ITB < 0,9 en el 43,2% (114), donde el 33,7% (89) refería síntomas de claudicación intermitente, mientras que un 9,5% (25) se encontraba asintomático. El mayor porcentaje de pacientes con EAOC EEII se observó en el grupo etario entre 60 y 80 años, que en conjunto alcanzaba el 85,1% de los pacientes con esta patología, siendo significativamente menor en pacientes menores de 60 y mayores de 80 años (p < 0,001). Conclusión: Encontramos una prevalencia de enfermedad arterial oclusiva crónica de extremidades inferiores de un 43,2% en pacientes de riesgo cardiovascular alto, quienes no presentaban este diagnóstico previamente. El índice tobillobrazo corresponde a un examen simple, rápido y con una gran utilidad diagnóstica por lo que debería considerarse su incorporación en las guías ministeriales para la evaluación de pacientes cardiovasculares en atención primaria.

Aim: The peripheral arterial disease (PAD) has been underestimated and underdiagnosed particularly at primary care setting. Our aim was to calculate the prevalence of PAD in high cardiovascular risk patients from a primary care center. Materials and Method: Is an observational, cross section study. We calculated a sample size of 246 patients, with a power of 80% and a significance level of 95%, who were selected randomly from 1.361 high cardiovascular risk patients according to the Framingham score, who attended at Cordillera Andina primary care center, measuring the anklebrachial index (ABI) in this group of patients. A 95% confidence interval was calculated for each mean and proportion and a p value less than 0.05 were considered as significant for all statistic tests. Results: We found an ABI < 0.9 in the 43.2% (114) of the sample, where 33.7% (89) presented symptoms of intermittent claudication, while 9.5% (25) did not have symptoms. The highest proportion of PAD was detected in patients between 60 and 80 years, who represented 85.1% of the patients with PAD, being significantly less its prevalence in people under 60 and over 80 years (p < 0.001). Conclusion: A prevalence of PAD of 43.2% in high cardiovascular risk patients who did not have this diagnosis before was found. The anklebrachial index is an easy, fast and very useful test to diagnose PAD in the majority of patients at primary care level, as consequent, its incorporation to clinical guidelines should be evaluated.

Cardiovascular Risk Factors in Patients with Chronic Kidney Disease Under Conservative Treatment

Abstract Background Cardiovascular disease (CVD) is commonly associated with chronic kidney disease (CKD). These diseases have a significant impact on life expectancy. Individuals with CKD are more likely to die from CVD than to progress to end-stage kidney disease. Objective To assess cardiovascular risk factors of patients with CKD under conservative treatment. Methods This was an observational, cross-sectional study. Socioeconomic, anthropometric, biochemical, and physical inactivity data were assessed, and 10-year risk for CVD were estimated using the Framingham Score in patients with CKD under conservative treatment. For statistical analysis, the Student's t-test and Pearson's chi-square test were performed. Results A total of 172 individuals were evaluated, 57% of whom were male, with an average age of 68.85 ± 11.41 years. The prevalence of hypertension and diabetes were 87.2% and 53.5%, respectively; 62.2% were physically inactive; 9.9% of men were smokers and 12.8% consumed alcohol. According to BMI, 82.4% of adults <60 years old and 60.6% of those older than 60 years were overweight. High waist circumference and a high waist-hip ratio were highly prevalent in females (91.9% and 83.8%, respectively) and males (64.3% and 39.8%, respectively); 92.4% had a high body fat percentage and 73.3% high uric acid levels. According to the Framingham score, 57% have a medium or high risk of developing CVD in 10 years. Conclusion There was a high prevalence of cardiovascular risk factors in the population studied. The assessment of cardiovascular risk factors in patients with CKD makes it possible to guide the conduct of health professionals to prevent mortality from cardiovascular causes.

Association Analysis of Hyperlipidemia with the 28-Day All-Cause Mortality of COVID-19 in Hospitalized Patients / 中国医学科学杂志(英文版)

Objective This study aimed to determine the association of hyperlipidemia with clinical endpoints among hospitalized patients with COVID-19, especially those with pre-existing cardiovascular diseases (CVDs) and diabetes. Methods This multicenter retrospective cohort study included all patients who were hospitalized due to COVID-19 from 21 hospitals in Hubei province, China between December 31, 2019 and April 21, 2020. Patients who were aged < 18 or ≥ 85 years old, in pregnancy, with acute lethal organ injury (e.g., acute myocardial infarction, severe acute pancreatitis, acute stroke), hypothyroidism, malignant diseases, severe malnutrition, and those with normal lipid profile under lipid-lowering medicines (e.g., statin, niacin, fenofibrate, gemfibrozil, and ezetimibe) were excluded. Propensity score matching (PSM) analysis at 1:1 ratio was performed to minimize baseline differences between patient groups of hyperlipidemia and non-hyperlipidemia. PSM analyses with the same strategies were further conducted for the parameters of hyperlipidemia in patients with increased triglyceride (TG), increased low-density lipoprotein cholesterol (LDL-C), and decreased high-density lipoprotein cholesterol (HDL-C). Mixed-effect Cox model analysis was performed to investigate the associations of the 28-days all-cause deaths of COVID-19 patients with hyperlipidemia and the abnormalities of lipid parameters. The results were verified in male, female patients, and in patients with pre-existing CVDs and type 2 diabetes. Results Of 10 945 inpatients confirmed as COVID-19, there were 9822 inpatients included in the study, comprising 3513 (35.8%) cases without hyperlipidemia and 6309 (64.2%) cases with hyperlipidemia. Based on a mixed-effect Cox model after PSM at 1:1 ratio, hyperlipidemia was not associated with increased or decreased 28-day all-cause death [adjusted hazard ratio (

Relationship between corticotherapy and increased cardiac risk in patients with rheumatoid arthritis

Rheumatoid arthritis is an autoimmune inflammatory joint disease with global prevalence of 0.4% to 1.0%. Extra-articular manifestations increase its morbidity and severity, and cardiovascular diseases present the greatest risk. Therapeutic approaches have been used to treat rheumatoid arthritis, often involving the use of multiple classes of drugs with different mechanisms and forms of action. Corticosteroid therapy is widely used in this therapeutic combination; however, its use has been widely questioned because of its high toxicity and some negative effects, including the possibility of increased cardiovascular risk, depending on the dosage. Some studies have provided important insights into how glucocorticoids have an impact on cardiac complications in patients with rheumatoid arthritis. Most of these studies have concluded that exposure to these drugs at high or cumulative doses is associated with increased risk of death, as well as possibly being associated with the presence of a positive rheumatoid factor.

Correlação ecocardiográfica da função diastólica do ventrículo direito com idade e gênero em indivíduos com função sistólica preservada / Echocardiographic correlation between right ventricular diastolic function and age and gender in subjects with preserved systolic function

Introdução: As funções sistólica e diastólica do ventrículo direito influenciam no desfecho de doenças cardiovasculares. A avaliação sistemática das dimensões e da função das câmaras direitas, de acordo com sexo e idade, não é uniformemente realizada. Objetivo: Avaliar, ao ecocardiograma transtorácico, a correlação da função diastólica do ventrículo direito com idade e sexo, em uma população ambulatorial variada, com função sistólica dos ventrículos esquerdo e direito preservada. Métodos: Estudo observacional, transversal. Foram selecionados 97 pacientes, 61,5 ± 12,5 anos, sendo 56 mulheres. Foram avaliadas as seguintes medidas da função diastólica do ventrículo direito: velocidade de pico das ondas E e A, relação E/A, tempos de aceleração e desaceleração de onda E, integral velocidade-tempo da onda E, integral velocidade-tempo da onda A, além da pressão sistólica de artéria pulmonar, velocidade do refluxo tricúspide, diâmetro da veia cava inferior e volume do átrio direito. Resultados: Ocorreu redução da onda E com o aumento da idade (coeficiente de correlação de Pearson de -0,30; p=0,003) e da relação E/A (coeficiente de correlação de Pearson de -0,21; p=0,035). Houve associação positiva e significativa entre idade e os resultados das variáveis pressão sistólica de artéria pulmonar (coeficiente de correlação de Pearson de 0,40; p=0,004) e velocidade do refluxo tricúspide (coeficiente de correlação de Pearson de 0,36; p=0,008). Não houve diferença significativa na comparação entre os sexos em relação a variáveis ecocardiográficas. Conclusão: O presente estudo mostrou impacto da idade nos índices de função diastólica do ventrículo direito em indivíduos com função sistólica biventricular preservada, embora ainda com valores dentro da normalidade. O estudo não evidenciou diferença significativa entre os sexos em relação a função diastólica do ventrículo direito. (AU)

Introduction: Right ventricular (RV) systolic and diastolic functions influence the outcomes of cardiovascular diseases. However, right chamber size and function have not been uniformly assessed by age and sex. Objective: To evaluate RV diastolic function by age and sex in an outpatient population with preserved left ventricular (LV) and RV systolic function using transthoracic echocardiography. Method: This observational cross-sectional study included a total of 97 patients (56 women) aged 61.5 ± 12.5 years. The assessed parameters included RV E/A ratio; peak E-wave and A-wave velocity, E-wave acceleration and deceleration time, and integral E-wave and A-wave velocitytime; and pulmonary artery systolic pressure (PASP), tricuspid reflux velocity, inferior vena cava diameter, and right atrial volume. Results: A reduced E-wave was observed with increasing age (Pearson's correlation coefficient [PCC], -0.30; p = 0.003). The same was observed for the E/A ratio (PCC, -0.21; p = 0.035). There was a significant positive association between age and PASP results (PCC, 0.40; p = 0.004) and tricuspid reflux velocity (PCC, 0.36; p = 0.008). There was no significant intersex difference in echocardiography variables. Conclusion: The present study showed the impact of age on RV diastolic function indices, which remained within the normal range, in subjects with preserved LV and RV function. The study did not evidence a significant difference between genders in relation to the diastolic function of the right ventricle.(AU)

Ácido úrico y gamma-glutamiltransferasa como biomarcadores de enfermedad cardiovascular a través del estrés oxidativo / Uric acid and gamma-glutamyltransferase as biomarkers of cardiovascular disease via oxidative stress

Introducción: Las enfermedades cardiovasculares constituyen la principal causa de mortalidad y morbilidad a nivel mundial. Reconocidas como problemas de salud de impacto social, han motivado a muchos científicos a tratar de explicar su patogénesis. Actualmente se plantea de la existencia de otros factores de riesgo, independientemente de los clásicos. Entre estos factores se describen el papel de las altas concentraciones de ácido úrico y la actividad de la enzima gamma-glutamiltransferasa en sangre, biomarcadores de estrés oxidativo. Estos elementos que de manera individual pudieran contribuir a las enfermedades cardiovasculares, parecen tener un efecto sinérgico. Objetivo: Revisar las evidencias que sostienen que altas concentraciones de ácido úrico y la actividad de la enzima gamma-glutamiltransferasa en sangre pueden constituir factores de riesgo que desde el estrés oxidativo contribuyan a las enfermedades cardiovasculares. Métodos: Se recopiló la información a partir de las bases de datos de diferentes buscadores (Medline-Pubmed, Cochrane, Scopus y SciELO) entre el 1 de marzo del 2019 y el 23 de mayo 2020. Conclusiones: Se encontró que, tanto el ácido úrico como la gamma-glutamiltransferasa son productos horméticos que a bajas concentraciones tienen efecto antioxidante en el organismo, pero al elevarse involucran la ocurrencia de procesos oxidativos que conducen a la disfunción endotelial y las enfermedades cardiovasculares(AU)

Introduction: Cardiovascular diseases are the leading cause of mortality and morbidity worldwide. Recognized as a health problem of social impact; they have prompted many scientists to try to explain their pathogenesis. New risk factors are currently acknowledged alongside the classic ones. These factors include the role of high uric acid concentrations and the activity of the enzyme gamma-glutamyltransferase in blood, both of which are biomarkers of oxidative stress. These elements may individually contribute to the development of cardiovascular diseases, and seem to have a synergistic effect. Objective: Review the evidence supporting the idea that high uric acid concentrations and the activity of the enzyme gamma-glutamyltransferase in blood may be risk factors contributing to the development of cardiovascular diseases via oxidative stress. Methods: Data were collected from the databases of various search engines (Medline-Pubmed, Cochrane, Scopus and SciELO) from 1 March 2019 to 23 May 2020. Conclusions: It was found that uric acid and gamma-glutamyltransferase are hormetic products causing an antioxidant effect on the organism at low concentrations. However, when concentrations rise, they are involved in the occurrence of oxidative processes leading to endothelial dysfunction and cardiovascular diseases(AU)

Cognitive impairment related to arterial stiffness in cardiovascular disease patients with severe periodontitis / Deterioro cognitivo relacionado a la rigidez arterial en pacientes con enfermedad cardiovascular y periodontitis grave

ABSTRACT Severe periodontal disease (SPD) associated with systemic peripheral inflammation, cognitive impairment (CI) and arterial stiffness (AS) has been recognized. The aim of this study was to investigate whether CI and arterial stiffness (AS) occur in cardiovascular disease (CVD) patients with SPD. A crosssectional case-control study included hospitalized patients with CVD. Demographic characteristics, CVD and atherogenic risk factors were recorded. SPD was diagnosed by clinical and radiographic dental examinations. Dental clinical attachment level (CAL) and CAL % were recorded. A Mini-Mental State Examination test (MMSE) assessed cognition, a MMSE score of < 27 was set as the cut-off point of CI; a score > 27 was considered as no CI. Patients were categorized into: MMSE<27 (cases) and MMSE>27 (controls). AS was evaluated by pulse wave velocity (PWV). Serum VCAM-1 levels were determined in a random sample. Results: This study comprised 91 patients (cases, n=26; 29.6%; controls, n=65, 71.4%); aged 73±8 vs. 73±7 years, respectively (p=0.73), of whom 53.8% and 36.9% respectively, were women; SPD was found to be a risk factor for CI; the presence of SPD increased the risk for MMSE <27 by an average 5.39 times (model 1). PWV was associated with MMSE < 27 in the three models. The risk of having MMSE < 27 increased an average of2.404-fold for each 1-unit increase in PWV SPD and AS had significant and independent associations on the risk for development CI. MMSE negatively correlated with CAL% (r=0.69) and PWV (r=0.70). PWV positively correlated with CAL% (r=0.67). Serum VCAM-1 levels were higher in SPD with lower MMSE scores. In conclusion, SPD increases the risk of development of cognitive decline in CVD patients. PWV was directly associated with the risk of cognitive decline. These findings denote a significant opportunity to improve periodontal health in order to avert CI in CVD patients.

RESUMEN La enfermedad periodontal severa (EPS) podría estar asociada a la rigidez arterial (RA) y al deterioro cognitivo (DC). Se realizó un estudio transversal de casos y controles y se investigó la presencia de RA y DC en pacientes con enfermedad cardiovascular (ECV) y EPS. En pacientes hospitalizados con ECVse registraron las características demográficas y factores de riesgo aterogénicos. El DC se diagnosticó a través del Mini-Mental State Examination (MMSE). Punto de corte: MMSE<27 (casos); puntaje >27 ausencia de DC (controles). La EPS fue diagnosticada clínica y radiográficamente. Se registraron el nivel inserción clínica (NIC) y NIC %. La RA fue evaluada a través de la velocidad de onda de pulso (VOP). VCAM-1 sérico se determinó en una muestra aleatoria. Se incluyeron 91 pacientes (casos,n=26; 29.6%; controles,n=65, 71.4%); edad promedio: 73±8 vs. 73±7 años, respectivamente (p=0.73); % de mujeres: 53.8 vs. 36.9, respectivamente y EPS (n=54) y ausencia de EP (noEP) en 37. MMSE< 27 en 26 pacientes; 23 de ellos, con EPS. La presencia de EPS aumentó el riesgo de MMSE< 27 en 5.39 veces (modelo 1). La VOP se asoció a MMSE< 27 (Modelo 1, 2 y 3). El riesgo de MMSE< 27 incrementó en promedio en 2.40 veces por cada aumento de unidad de VOP. EPS y RA mostraron asociaciones significativas e independientes sobre el riesgo de DC. MMSE se correlacionó negativamente con NIC % (r=0.69) y POV (r=0.70); y POV, positivamente con NIC % (r=0.67). Los niveles séricos de VCAM-1 fueron más elevados en presencia de EPS y puntajes bajos de MMSE. Puede concluirse que en pacientes con ECV y EPS, el aumento en RA incrementaría el riesgo de DC. Estos hallazgos enfatizan la necesidad de promover y mantener la salud bucal para evitar el DC en pacientes con ECV.

Prevalence of Malnutrition and Its Association with Clinical Complications in Hospitalized Cardiac Patients: Retrospective Cohort Study

Abstract Background Malnutrition can affect the clinical course of hospitalized patients, increasing hospital stay, infections, mortality, and hospital costs. Among heart disease patients, the malnutrition prevalence ranges from 25 to 51.9%. Objective To assess the prevalence of malnutrition and its association with clinical complications in cardiac patients admitted to a cardiology hospital. Method Retrospective cohort study with patients evaluated within 48 hours of admission to the ward of a referral center for cardiology in Porto Alegre, Brazil. Patients were aged 18 years or older. Malnutrition was assessed by Subjective Global Assessment. Length of hospital stay, transfer to the intensive care unit (ICU), hospital discharge and in-hospital death were collected from medical records. Statistical analysis was performed using the SPSS 22.0 program. Comparisons between groups with and without malnutrition were made by unpaired Student's t-test and chi-square test with adjusted residuals, and multivariate Poisson regression used for analysis of outcomes. The significance level considered was 5%. Results We evaluated 130 patients aged 63 ± 13 years, 63% were male, and the most frequent cause of hospitalization was angina (25%).
