1. Como manejar pacientes com indicação de uso de antiplaquetários que tiveram sangramento digestivo alto?
O uso de AAS em dose baixa (até 100 mg) associado ao uso contínuo de inibidor da bomba de prótons (IBP) é a estratégia preferencial para prevenção secundária de eventos cardiovasculares. AAS tamponado não é eficaz para redução de sangramentos. Em pacientes com infecção por Helicobacter Pylori, deve-se indicar também a erradicação.

2. Todos os pacientes com sintomas compatíveis com esofagite de refluxo devem realizar Endoscopia Digestiva Alta?
Essa resposta será fundamentada no Consenso Brasileiro de Doença do Refluxo Gastroesofágico (DRGE) e portanto tem grau de recomendação D. O tratamento da DRGE objetiva primariamente o alívio dos sintomas, a cicatrização das lesões e a prevenção de recidivas e complicações. É importante considerar na abordagem inicial do paciente a idade e a

4. Outcome of Gastroesophageal Reflux Therapy in Children with Persistent Otitis Media with Effusion
Abstract Introduction Otitis media with effusion (OME) is considered one of the most common disorders that affect children during the first years of life. There are many risk factors of persistent middle ear effusion; one of these risk factors is gastroesophageal reflux. Association between persistent OME and gastroesophageal reflux diseases (GERDs) could b

5. The Influence of the Platinum Weight Percentage in the Catalyst Formulation on the Performance of a High Temperature Ethanol Electroreformer Based on H3PO4 Doped Polybenzimidazole for Green Hydrogen Production
A vapor-fed high temperature proton exchange ethanol electroreformer has been developed based on the use of a H3PO4-doped polybenzimidazole membrane to produce green hydrogen. As a key parameter, this article describes the influence of platinum weight percent (wt.%) in the catalyst formulation from different commercial catalysts (20, 40, 60, 80 wt.% Pt/C and

6. High prevalence of functional dyspepsia in nonalcoholic fatty liver disease: a cross-sectional study
Abstract BACKGROUND: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE:

8. A Theoretical Antioxidant Mechanism for Cytoprotective Effect of p-Acetamide-Salicylate Derivatives against Free Radical Initiator AAPH in Human Erythrocytes
The molecular mechanism of cytoprotective effect on human erythrocytes of aminophenol and salicylates associated derivatives was related to their antioxidant capacity. The oxidative hemolysis induced by water-soluble free-radical initiator 2,2’-azobis-(2-amidine-propane)-dihydrochloride (AAPH) was inhibited by drug candidates named benzaminophen (BZL), sal

9. STUDY ON THE OPTIMIZATION FOR THE SIZE OF FUEL CELL FLOW FIELD UNDER INADEQUATE AIR SUPPLY CONDITION
In this paper, the influence of the optimization for flow field size on the proton exchange membrane fuel cell (PEMFC) performance under the inadequate air supply of cathode was studied based on the three-dimensional, steady-state, and constant temperature PEMFC monomer model. Additionally, the effect of the optimization for hybrid factors, including length,

10. EVALUATION OF THE CHEMICAL COMPOSITION AND STRUCTURE OF ASPHALTENES FROM THREE OFFSHORE BRAZILIAN BIODEGRADED HEAVY OILS
Asphaltenes fractions were extracted and purified from three heavy Brazilian oils. Their mass compositions of C, H, N, Ni and V were obtained from elemental analysis and S and O atomic percentages from EDS. The H/C ratios showed high degree of unsaturation, while the O atomic percentages indicated more pronounced biodegradation effects on two samples. Quanti

11. Association between fractures and traditional risk factors for osteoporosis and low bone mineral density in patients with obesity
ABSTRACT Objective: To evaluate the reasons for request of bone mineral density (BMD) evaluation and correlate the BMD results with previous fractures, risk factors for osteoporosis, and clinical characteristics in patients with obesity. Subjects and methods: Cross-sectional, retrospective, single-site study including adult patients with body mass index (B

12. Laryngopharyngeal Reflux: Symptoms, Signs, and Presence of Pepsin in Saliva - A Reliable Diagnostic Triad
Abstract Introduction Twenty-four-hour multichannel intraluminal impedance with double probe pH monitoring (MII-pH), though considered the most sensitive tool for the diagnosis of gastroesophageal reflux disease (GERD), is invasive, time consuming, not widely available, and unable to detect non-acid reflux. In contrast, the presence of pepsin in the saliva
