Objectives: The objective of the study was to evaluate the factors associated with symptoms of posttraumatic stress in mothers during the COVID-19 pandemic.
Methods: Cross-sectional study conducted with mothers of children and adolescents living in Brazil, who answered an online questionnaire containing sociodemographic variables and the Impact of Events Scale-Revised. The Poisson regression model with robust variance was used to identify the factors associated with posttraumatic stress.
Background: Microscopy is a resource used in endodontics as an aid in the study of pulp and periapical pathologies; it has allowed Endodontics to become more accurate, less invasive and has enabled greater chances of success in treatment. We aimed to map the scientific production on "microscopy" and "endodontics" in the databases, the ISI Web of Knowledge/Web of Science .
Methods: This bibliometric survey was conducted using ISI Web of Knowledge/Web of Science database, in the time frame between the years 1945 and 2016, the first being found in 1981.

Background: The New York Heart Association (NYHA) functional classification is the most commonly used classification system for heart failure (HF), whereas cardiopulmonary exercise testing (CPET) is the gold standard for functional status evaluation in HF.
Objective: This study aimed to analyze correlation and concordance between NYHA classes and CPET variables.
Methods: HF patients with clinical indication for CPET and ejection fraction (EF) < 50% were selected.
Background: Left ventriculography is an invasive method for assessment of left ventricular systolic function. Since the advent of noninvasive methods, its use has been questioned, as it carries some risk to the patient.
Objective: To assess which factors are independently associated with the decision to perform ventriculography in patients with coronary artery disease.
