title: Echocardiographic Assessment of Right Ventricular Function by Two-Dimensional Strain In Patients with Left-Sided Valvular Heart Disease: Comparison with Three-Dimensional Echocardiography

description: Abstract Background: Right ventricular (RV) dysfunction is a well-known predictor of mortality in patients with valvular heart disease (VHD). The assessment of RV function is often difficult due to complex geometry and hemodynamic factors. We aim to analyze RV function in patients with severe mitral and/or aortic valve disease using two-dimensional strain (2DS) imaging and conventional echocardiographic parameters, comparing it with right ventricular ejection fraction (RVEF) measured by three-dimensional echocardiography (3DE). Methods: Fifty-three patients with severe mitral and/or aortic VHD underwent complete transthoracic echocardiogram in the preoperative setting for cardiac surgery, including conventional echocardiographic parameters of RV function and speckle-tracking derived 2DS indices: RV global longitudinal strain (RVGS) and RV free wall longitudinal strain (RVFWS). Conventional echocardiographic and 2DS parameters were compared with real-time 3DE RVEF using Spearman correlation test. For comparison between two groups of patients based on the presence of RV dysfunction (normal RVEF ≥ 44% - A, abnormal RVEF &lt; 44% - B), we used nonparametric Mann-Whitney U test. ROC (receiver operating characteristic) curve analysis was used to assess the clinical utility of all RV function variables in defining RV dysfunction. P values &lt;0,05 were considered statistically significant. Results: We found a significant correlation between all parameters and RVEF (p&lt;0.05), with best results for RV fractional area change (FAC), RVGS, and RVFWS. Dividing the population into two-groups based on RVEF, we found 14 patients with RV dysfunction (27.4%), and significant differences between the groups for all RV function variables. For detection of RV dysfunction defined by 3DE, ROC curve analysis showed the best area under the curve (AUC) for RVGS (0.872), RVFWS (0.851) and FAC (0.932). Conclusions: We observed significant correlation between RVGS, RVFWS and RVEF, with good accuracy in detecting RV dysfunction, comparable to FAC and better than other conventional parameters of RV function assessment. The evaluation of RV myocardial deformation with 2DS may have additional diagnostic and prognostic value in patients with severe left-sided VHD.

title: Prevalence of Metabolic Syndrome in Three Regions in Venezuela: The VEMSOLS Study

description: Abstract Background: No previous study has evaluated the prevalence of metabolic syndrome (MS) in more than one region in Venezuela. Objective: To determine the prevalence of MS in three Venezuelan regions. Methods: From 2006 to 2010, a total of 1,320 subjects aged ≥ 20 years were selected by multistage stratified random sampling from the regions of Lara State (western region), Mérida State (the Andean region), and Capital District (Capital Region). Anthropometric measurements, blood pressure, and biochemical analysis were obtained from each participant. MS was defined according to the harmonized Joint Interim Statement (2009) definition. Results: Mean age was 44.8 ± 0.39 years and 68.5% of the participants were female. The overall prevalence of MS was 35.7% (95% confidence interval 32.2 - 39.2%), while the prevalence was 42.5% (95% CI 38.8 - 46.1%) among men and 32.6% (95% CI 29.1 - 36.0%) among women (p &lt; 0.001). In women, the prevalence of MS increased at almost every decade of life, while in men, the prevalence was similar from the age of 30 years onwards. The most prevalent abnormalities were low HDL-c levels (58.6%, 95% CI 54.9 - 62.1%), abdominal obesity (52.0%, 95% CI 48.4 - 55.7%), and elevated triglycerides levels (39.7%, 95% CI 36.1 - 43.2%). The prevalence of MS increased with increasing body mass index categories. Conclusion: In Venezuela, MS is a highly prevalent condition, which increases the risk of type 2 diabetes and cardiovascular disease in a large number of subjects.

title: Prevalence of Physical Inactivity and its Effects on Blood Pressure and Metabolic Parameters in a Brazilian Urban Population

description: Abstract Background: Cardiovascular disease is the leading cause of mortality in the world and physical inactivity represents an important risk factor. Objective: This study aimed to evaluate the prevalence of physical inactivity in the adult population and its effects on blood pressure, blood glucose and lipid profile. Methods: A population-based cross-sectional study with stratified simple random sampling was conducted in 1,717 adults divided by age groups: 18-39, 40-49, 50-59, 60-69 and ≥ 70 years. The participants answered the physical activity questionnaire and were classified as physically active or inactive. The bootstrap statistical method was used to assess physical activity, associated with lipid profile and blood glucose levels. The level of significance was 5%. Results: The prevalence of physical inactivity in the general population was 65.8%. There was a significant difference in the group older than 70 years. There was a significant decrease in physical activity in the group with lower educational level, with a significant difference between social classes AB and C. The prevalence of hypertension was 27.5% among physically inactive and 21.4% among active individuals (p = 0.04). The prevalence of metabolic syndrome was 26.1% in inactive and 16.7% in the active individuals (p = 0.007). Total cholesterol, low-density lipoprotein and triglycerides levels were more elevated in the physically inactive group, which was not observed with high-density lipoprotein levels. Blood glucose was also higher in the inactive group. Conclusion: This study shows a high prevalence of physical inactivity and a positive correlation between risk factors for cardiovascular disease, mainly blood pressure, glucose and lipids profiles.

title: Option for the Radial versus Femoral Access in Coronary Intervention in Acute Coronary Syndromes: A Risk-Treatment Paradox

description: Abstract Background: In coronary procedures, although the radial approach protects patients from hemorrhagic complications, it is technically more complex than the femoral approach. Objectives: To test the hypothesis that the radial approach is the procedure of choice in ACS patients due to the high risk of bleeding; and to identify independent predictors of the choice for radial access. Methods: Patients admitted for ACS who underwent invasive coronary procedure were included. We registered the type of access (femoral or radial) chosen by the physician for the first angiography; the investigators did not interfere with this choosing process. Student’s t-test was used for comparisons between the CRUSADE and ACUITY scores. Predictors of radial access were compared between the groups. Statistical significance was defined by p &lt; 0,05. Results: Radial access was chosen in 67% of 347 consecutive patients. Patients who underwent radial approach had lower risk of bleeding determined by CRUSADE (30 ± 14 vs. 37 ± 15; p &lt; 0.001) as compared with femoral access. In multivariate analysis, four variables were identified as independent predictors negatively associated with radial access - age (OR = 0.98; 95%CI = 0.96 - 0.99), creatinine (OR = 0.54; 95%CI = 0.3 - 0.98), signs of left ventricular failure (OR = 0.45; 95% CI = 0.22 - 0.92) and previous CABG (OR = 0.022; 95%CI = 0.003 - 0.166). Conclusion: The propensity to choose radial over femoral access in coronary intervention was not primarily influenced by patients’ bleeding risk. Predictors of this decision, identified in the study, indicated less complex patients, suggesting that the difficulty in performing the technique was a stronger determinant than its potential antihemorrhagic effect.

title: Germination, viability and longevity of horseweed (Conyza spp.) seeds as a function of temperature and evaluation periods

description: ABSTRACT: In Brazil, horseweed is one of the most important weeds because of the resistance to herbicides and high competitive for the crops. A large of losses were reported in major crops such as soybeans, wheat and corn, where the use a no-tillage system and the herbicide resistance promote better establishment. A correct understanding of the way temperature influences germination enables the prediction of the regions with the highest potential for colonization by this weed and thus facilitates its control. The objective of this study; therefore, was to discern the ways temperature affected the germination, viability and longevity of horseweed seeds. Testing was done at 10, 20 and 30°C, while evaluation occurred on days 0, 15, 30, 45 and 60. Seeds were packed in a nylon mesh bag (5x5cm), with 10g of upland soil (Yellow Red Argissolo, sandy loam texture), placed in transparent plastic boxes at 0 to 0.5cm soil depth, at the temperatures specified. Percentage of remaining seeds, first and second germination counts, abnormal seedlings, and dead, dormant, viable and non-viable seeds, were assessed. Horseweed seeds achieve secondary dormancy at 10, 20 and 30°C, while their quality and the longevity showed damage at 20 and 30°C temperatures.

title: Assessment of professional competence of nurses in emergencies: created and validated instrument

description: ABSTRACT Objective: To create an instrument to assess the professional competence of nurses in emergencies. Method: Methodological study carried out between 2013 and 2016 in a Brazilian university. We used the Pasquali's model and Psychometrics as references because they allow subjective phenomena to be measured. The survey covered defining steps of the behavior to be measured, the formulation of the items in the instrument, development of instructions for using the instrument and elements necessary to demonstrate validity evidence. Although we have previously performed, in a distinct and consecutive way, the literature review, definition of the Core (or Matrix) Competence and the Competence Profile, and identification of validity with Delphi, essential components to structure a technology, in this step we continued the conclusion of these Theoretical Procedures. Result: We created an instrument for self- and/or hetero-evaluation containing: personal/professional/academic characterization, Competency Scale, fictitious cases and actions representing the practice. Conclusion: We created a new soft-hard technology based on the validity evidence of contents according to experts of the five regions of Brazil.
