Pulmonary arteriovenous malformations: diagnostic and treatment characteristics

J. bras. pneumol; 45 (4), 2019
ABSTRACT Objective: To present a case series of pulmonary arteriovenous malformations (PAVMs), describing the main clinical findings, the number/location of pulmonary vascular abnormalities, the clinical complications, and the treatment administered. Methods: This was a retrospective observational stud...

Cardiovascular risk in children and adolescents with end stage renal disease

Clinics; 74 (), 2019
OBJECTIVES: To evaluate cardiovascular involvement in children and adolescents with End Stage Renal Disease (ESRD) and to characterize the main risk factors associated with this outcome. METHODS: Cross-sectional study of 69 children and adolescents at renal transplantation and 33 healthy individuals mat...

YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy

Braz. j. med. biol. res; 52 (1), 2019
Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac ma...

Trastornos de la conducta alimentaria: alteraciones cardiovasculares al ingreso y evolución a 3 meses

Rev. méd. Chile; 147 (1), 2019
Background: Cardiovascular complications can occur in up to 80% of adolescent patients with eating disorders (ED) and account for 30% of their mortality. Aim: To evaluate cardiovascular complications in adolescents with ED and their evolution after refeeding. Patients and Methods: In adolescents with E...

Evaluación de la corrección angular de la integral velocidad tiempo en ecocardiografía. Estudio piloto
Evaluation of the angular correction of the integral velocity time in echocardiography. Pilot study

Background: Echocardiography has now a pivotal role as a tool for hemodynamic monitoring, particularly in the critically ill. However, the ideal acoustic window for relevant measurements such as the velocity time integral are not always available. We propose to evaluate if angular correction of this v...

Evaluation of volume responsiveness by pulse pressure variability and inferior vena cava dispensability index at different tidal volumes by mechanical ventilation

Braz. j. med. biol. res; 52 (9), 2019
This study investigated the effects of tidal volume (TV) on the diagnostic value of pulse pressure variation (PPV) and the inferior vena cava dispensability index (IVC-DI) for volume responsiveness during mechanical ventilation. In patients undergoing elective surgery with mechanical ventilation, differe...

Cardiac function and intracellular Ca2+ handling proteins are not impaired by high-saturated-fat diet-induced obesity

Braz. j. med. biol. res; 52 (6), 2019
Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in myocardial ...

Epidemiological features, echocardiographic findings, and parasite load in patients with Chagas disease

Abstract INTRODUCTION Chagas disease is a major public health problem that is endemic in Brazil and Latin America. This study aimed to determine the socioeconomic, demographic, and clinical characteristics of 171 patients (mean age, 45 years; female, 65%) with Chagas disease at Hospital Universitário ...

Disease activity is associated with LV dysfunction in rheumatoid arthritis patients without clinical cardiovascular disease

Adv Rheumatol; 59 (), 2019
Abstract Objectives: The cross-sectional study aimed to assess left ventricular systolic function using global longitudinal strain (GLS) by speckle-tracking echocardiography (STE) and arterial stiffness using cardio-ankle vascular index (CAVI) in Thai adults with rheumatoid arthritis (RA) and no clinica...
