1. Therapeutics in Radiation-induced Proctopathy: A Systematic Review
Abstract Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to min

2. Surgical Mortality in Infective Endocarditis: Is There a Gender Paradox?
Abstract The atrioventricular (AV) reentrant tachycardia (AVRT) is the most common cause of supraventricular tachycardia (SVT) in the young pediatric population. Some newborns might present with congestive heart failure and require interventional treatment. Catheter ablation in small infants (<6 months and <5 kg) is still poorly performed and controversial d

4. Development of a Simple and Fast Procedure Based on Acid Dilution for Determination of Macro and Microelements in Guarana-Based Beverages by ICP OES
A simple analytical procedure is proposed for the direct analysis of guarana-based beverages in order to determine nutrient elements by inductively coupled plasma optical emission spectrometry (ICP OES). A Box-Behnken design, combined with Derringer’s desirability function, was applied to the simultaneous optimization of the ICP OES radiofrequency (RF), sa

5. Left Atrial Appendage Thrombosis and Persistent Atrial Fibrillation: combined Treatment with a Totally Thoracoscopic Approach
Abstract Minimally invasive surgical ablation is generally contraindicated in patients with atrial fibrillation and thrombosis of the left atrial appendage. We have treated three of these patients using an innovative technique based on a bilateral video-thoracoscopic approach, performing a continuous encircling lesion at the pulmonary veins outflow with radi

12. Radiofrequency catheter ablation increases mean platelet volume
RESUMO OBJETIVOS A ablação por radiofrequência (ARF) pode aumentar o risco de eventos tromboembólicos. O objetivo foi avaliar o efeito da ARF no volume plaquetário médio (VPM), um indicador de atividade plaquetária. MÉTODO No total de 95 pacientes submetidos à ARF, o VPM foi medido antes e um mês após o procedimento. Oitenta e três pessoas do
