2. The Relationship Between Mitral Annular Calcification, Metabolic Syndrome and Thromboembolic Risk
Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic st

3. AlradSpectra: a Quantification Tool for Soil Properties Using Spectroscopic Data in R
ABSTRACT Soil reflectance spectroscopy has become an innovative method for soil property quantification supplying data for studies in soil fertility, soil classification, digital soil mapping, while reducing laboratory time and applying a clean technology. This paper describes the implementation of a Graphical User Interface (GUI) using R named AlradSpectra.

4. The CHA2DS2-VASc score for predicting atrial fibrillation in patients presenting with ST elevation myocardial infarction: prospective observational study
ABSTRACT BACKGROUND: Atrial fibrillation (AF) is the most common form of supraventricular arrhythmia following ST-elevation myocardial infarction (STEMI). The CHA2DS2-VASc and CHADS2 scores are used to estimate thromboembolic risk in cases of AF. Their usefulness in predicting the development of AF in patients presenting STEMI is unknown. OBJECTIVE: To e

5. Does Crop-Livestock-Forest Systems Contribute to Soil Quality in Brazilian Savannas?
ABSTRACT In this paper we discuss the impact on conversion degraded pasture areas into an integrated crop, livestock and forest system (ICLFS). We collected 30 soil samples at 0-0.1 m depth in five agroforestry systems, degraded pasture and native areas along Brazilian Cerrado biome. We analyzed the influence of chemical variables on microbial biomass carbon

6. Manutenção do trabalho e presença de condições crônicas em idosos comunitários: evidências da Rede Fibra-BH
Resumo Este estudo transversal foi conduzido em uma amostra probabilística de 597 idosos comunitários residentes em Belo Horizonte, com o objetivo de avaliar quais condições crônicas apresentam associações independentes com a permanência do idoso no mercado de trabalho, a fim de verificar a influência de cada uma isoladamente. A análise multivariad

7. The Relation Between Echocardiographic Epicardial Fat Thickness and CHA2DS2-VASc Score in Patients with Sinus Rhythm
Abstract Objective: To evaluate the predictive value of epicardial fat thickness (EFT) in CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, age 65-74 years, sex category) score risk groups. Methods: A total of 158 consecutive patients (75 females, 83 mal

8. Score for atrial fibrillation detection in acute stroke and transient ischemic attack patients in a Brazilian population: The acute stroke atrial fibrillation scoring system
OBJECTIVE: Atrial fibrillation is a common arrhythmia that increases the risk of stroke by four- to five-fold. We aimed to establish a profile of patients with atrial fibrillation from a population of patients admitted with acute ischemic stroke or transient ischemic attack using clinical and echocardiographic findings. METHODS: We evaluated patients conse

9. Utility of a novel risk score for prediction of ventricular tachycardia and cardiac death in chronic Chagas disease - the SEARCH-RIO study
The SEARCH-RIO study prospectively investigated electrocardiogram (ECG)-derived variables in chronic Chagas disease (CCD) as predictors of cardiac death and new onset ventricular tachycardia (VT). Cardiac arrhythmia is a major cause of death in CCD, and electrical markers may play a significant role in risk stratification. One hundred clinically stable outpa

10. USO DE REGRESSÃO MÚLTIPLA NO ESTUDO DA DINÂMICA DE CARBONO, NITROGÊNIO E FÓSFORO EM UM SISTEMA SOLO-PLANTA IRRIGADO COM ÁGUA RESIDUÁRIA
A preocupação com a diminuição na oferta de água potável tem implicado na busca por fontes alternativas, particularmente, para atividades agrícolas. A utilização de efluente de tratamento secundário de esgoto (ETSE) na irrigação das culturas tem sido prática comum em diversas situações de clima e solo. Todavia, as mudanças ocorridas no sistem

11. PRESSUPOSTO DA NORMALIDADE MULTIVARIADA PARA O TESTE DE RAZÃO DE VEROSSIMILHANÇA ENTRE DOIS GRUPOS DE CARACTERES DE MAMONEIRA / ASSUMPTION OF MULTIVARIATE NORMALITY FOR THE LIKELIHOOD RATIO TEST BETWEEN TWO GROUPS OF CHARACTERS OF CASTOR BEANS
The likelihood ratio test for independence between two groups of variables allows us to identify whether there is a dependency relationship between two groups of variables, ie, if the covariance between the two groups are zero. This test assumes normality multivariate data, which limits its application, in many studies of agronomic area, times when you need

12. Divergência genética entre acessos de Capsicum chinense Jacq. coletados no sudoeste goiano / Genetic divergence among Capsicum chinense Jacq accesses collected in southwest Goiás Brazil
Collecting and characterization of Capsicum chinense Jacq accesses are very important to recover and preserve genetic resources of this species; however, it is necessary to quantify the existing divergence for its use in breeding programs. The objective of this work was to verify the genetic divergence of 137 accesses of Capsicum chinense Jacq collected in s
