Validation of the urgency questionnaire in Portuguese: A new instrument to assess overactive bladder syndrome

Int. braz. j. urol; 44 (2), 2018
ABSTRACT Purpose Overactive Bladder (OAB) is a clinical condition characterized by symptoms reported by patients. Therefore, measurement instruments based on reported information are important for understanding its impact and treatment benefits. The aim of this study was to translate, culturally adapt a...

Validity time of normal results of preoperative tests for surgical reintervention and the impact on postoperative outcomes

Rev. bras. anestesiol; 68 (2), 2018
Abstract Background and objective: There are few data defining the period of time in which preoperative tests can be considered valid. The purpose of this study was to determine the likelihood of changes in the results of preoperative tests previously normal in relation to time, and the impact of these ...

Predictors of outcomes after correction of acute type a aortic dissection under moderate hypothermic circulatory arrest and antegrade cerebral perfusion

Abstract Introduction: Hypothermic circulatory arrest is widely used for correction of acute type A aortic dissection pathology. We present our experience of 45 consecutive patients operated in our unit with bilateral antegrade cerebral perfusion and moderate hypothermic circulatory arrest. Methods: Be...

Effect of ischemic postconditioning and atorvastatin in the prevention of remote lung reperfusion injury

Abstract Objective: The aim of the present study was to evaluate the ability of ischemic postconditioning, atorvastatin and both associated to prevent or minimize reperfusion injury in the lung of rats subjected to ischemia and reperfusion by abdominal aortic clamping. Methods: We used 41 Wistar norveg...

Aortic valve replacement with a conventional stented bioprosthesis versus sutureless bioprosthesis: a study of 763 patients

Abstract Objective: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy. Methods: From January 2011 to December 2016, 763 patients un...

Use of doppler ultrasound for saphenous vein mapping to obtain grafts for coronary artery bypass grafting

Abstract Introduction: The great saphenous vein is widely used as a graft in coronary artery bypass grafting surgery. Complications due to saphenous vein harvesting can be minimized when using ultrasonography mapping and marking. Objective: To analyze by clinical trial the use of vascular ultrasonograp...

On-Pump beating/non-beating cabg in stable angina have similar outcomes

Abstract Objective: On pump beating/non-beating coronary artery bypass grafts (CABG) has been compared in patients with unstable angina and/or severe left ventricular dysfunction. There is scarce evidence regarding the beneficial use of on-pump beating CABG in patients with stable angina and normal left...

Tamizaje de episodio depresivo en adolescentes: validación del instrumento PHQ-9

Rev. méd. Chile; 146 (4), 2018
Background: There is a paucity of validated instruments for screening depression in adolescent populations in Chile. Aim: To determine the diagnostic accuracy of the adolescent version of Patient Health Questionnaire-9 (PHQ-9). Material and Methods: The PHQ-9 was transculturally adapted and administere...

Influence of Aerobic Training on The Mechanics of Ventricular Contraction After Acute Myocardial Infarction: A Pilot Study

Arq. bras. cardiol; 110 (4), 2018
Abstract The study of myocardial contractility, based on the new anatomical concepts that govern cardiac mechanics, represents a promising strategy of analysis of myocardial adaptations related to physical training in the context of post-infarction. We investigated the influence of aerobic training on ph...

Applicability of Longitudinal Strain of Left Ventricle in Unstable Angina

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Unstable angina (UA) is a common cause of hospital admission; risk stratification helps determine strategies for treatment. Objective: To determine the applicability of two-dimensional longitudinal strain (SL2D) for the identification of myocardial ischemia in patients with UA. Me...
