Knowledge about epilepsy in university health students: A multicenter study.

Even with economic development and improvements in health care around the world, it is estimated that nowadays, 50 million people have epilepsy. It is one of the most prevalent neurological diseases, yet it is still surrounded by prejudice, stigma, lack of awareness, and wrong attitudes of the population towards the disease. The aim of this study was to evaluate and compare the knowledge about epilepsy in health students from different countries: Brazil, Argentina, Portugal, United States, and South Africa. Students were asked to complete a survey regarding knowledge about epilepsy (the Epilepsy Knowledge Questionnaire). One hundred and two students participated, 62.2% of them were female. Portuguese students had significantly higher values than the American ones (p=0.025). Regarding the medical aspects, on average, students hit 63.8% of the questions, and the students from Portugal had significantly higher average than the ones from the United States (p=0.0007). Statements with lower percent of correct answers were about pathophysiology, medication, and treatment of the disease. There were no differences between the scores obtained by the students of each country in the social aspects of the disease. Statements with higher percent of mistakes were about sports practice, labor, proceedings in case of convulsion, and ability to drive vehicles. General knowledge of senior health students about epilepsy was considered low, however, regarding the medical aspects of the disease, students from Brazil and Portugal exhibited a slightly superior knowledge. Changing the way of seeing and treating people with epilepsy brings, as a consequence, increased opportunities for these people in different sectors of society.

Exercise Training Attenuates Right Ventricular Remodeling in Rats with Pulmonary Arterial Stenosis.

Introduction: Pulmonary arterial stenosis (PAS) is a congenital defect that causes outflow tract obstruction of the right ventricle (RV). Currently, negative issues are reported in the PAS management: not all patients may be eligible to surgeries; there is often the need for another surgery during passage to adulthood; patients with mild stenosis may have later cardiac adverse repercussions. Thus, the search for approaches to counteract the long-term PAS effects showed to be a current target. At the study herein, we evaluated the cardioprotective role of exercise training in rats submitted to PAS for 9 weeks. Methods and Results: Exercise resulted in improved physical fitness and systolic RV function. Exercise also blunted concentric cavity changes, diastolic dysfunction, and fibrosis induced by PAS. Exercise additional benefits were also reported in a pro-survival signal, in which there were increased Akt1 activity and normalized myocardial apoptosis. These findings were accompanied by microRNA-1 downregulation and microRNA-21 upregulation. Moreover, exercise was associated with a higher myocardial abundance of the sarcomeric protein α-MHC and proteins that modulate calcium handling-ryanodine receptor and Serca 2, supporting the potential role of exercise in improving myocardial performance. Conclusion: Our results represent the first demonstration that exercise can attenuate the RV remodeling in an experimental PAS. The cardioprotective effects were associated with positive modulation of RV function, survival signaling pathway, apoptosis, and proteins involved in the regulation of myocardial contractility.
