1. Hemodynamic outcome of different ventilation modes in laparoscopic surgery with exaggerated trendelenburg: a randomised controlled trial
Abstract Purpose: To compare hemodynamic effects of two different modes of ventilation (volumecontrolled and pressure-controlled volume guaranteed) in patients undergoing laparoscopic gynecology surgeries with exaggerated Trendelenburg position. Methods: Thirty patients undergoing laparoscopic gynecology operations were ventilated using either volume-contr

2. Effects of Cardiac Resynchronization Therapy on a Six-minute Walk Test, Maximal Inspiratory Pressure and Peak Expiratory Flow in Patients with Heart Failure: A Longitudinal Study
Abstract Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with heart failure. Objective: To evaluate the response of CRT in maximal inspiratory pressure (MIP), peak expiratory flow (PEF), and exercise tolerance as determined by the six-minute walk test (6MWT) in patients with HF. Methods: This study used the 6MWT

3. Multiphysics Design of High-Power Microwave Vacuum Window
Abstract This paper presents the Multiphysics Analysis of a High-Power Microwave Window for a Ka-Band Klystron providing 16MW of peak power. After the optimization of the electromagnetic performances, we analyze the effect of RF heating effect and the stress of the pressure on the window. We also analyze the multipactor effect, that is a common cause of wind

4. Impact of drains positioning on pulmonary function after coronary artery bypass grafting: an observational study
Abstract Introduction: Coronary artery bypass grafting (CABG) is a procedure associated with a decline in pulmonary function. Among the main causes is the presence of the drain that is usually positioned in the intercostal or subxiphoid region. Objective: To measure the interference of drains positioning on pulmonary function in patients undergoing CABG.

5. Intra and intersession repeatability and reliability of dynamic parameters in pressure platform assessments on subjects with simulated leg length discrepancy. A cross-sectional research
ABSTRACT BACKGROUND: Leg length discrepancy (LLD) may play a key role in exercise biomechanics. Although the Podoprint platform has been used in dynamic pressure studies, there are no data regarding the reliability and repeatability of dynamic measurements under simulated LLD conditions. OBJECTIVES: To determine the intra and intersession repeatability and

6. Effects of Inspiratory Muscle Training Using an Electronic Device on Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial
Abstract Background Cardiac surgery causes pathophysiological changes that favor the occurrence of pulmonary and functional complications. Objective To investigate the effects of inspiratory muscle training (IMT) with an electronic device on patients undergoing cardiac surgery. Methods A randomized controlled trial was conducted with 30 adult patients

7. Study of Arterial Stiffness - Based on Scientific Evidence, What are the Current Tools for the Study of Arterial Stiffness?
Abstract Background The European Heart Surgery Risk Assessment System (EuroSCORE) and InsCor have been used to predict complications of cardiac surgery. However, their application to predict lung function and functionality is still uncertain. Objective To correlate surgical risk scales with functional independence and pulmonary function in patients under

9. Gasparyan Method of Total Autologous Reconstruction of the Aortic Valve
Abstract In this case report, I describe a new technique for total reconstruction of the aortic valve with autologous pericardium. The parameters of the cusps were calculated using very simple formulas after measurement of the aortic root intercommissural distances. Glutaraldehyde-treated pericardium was trimmed along the marked line, leaving 2 mm of tissue

10. Comparison of automated irrigation systems using an in vitro ureteroscopy model
ABSTRACT Introduction: Two automated irrigation systems have been released for use during endoscopic procedures such as ureteroscopy: the Cogentix RocaFlow® (CRF) and Thermedx FluidSmart® (TFS). Accurate pressure control using automated systems may help providers maintain irrigation pressures within a safe range while also providing clear visualization. O

11. A Tribute to a Master: Professor Domingo M. Braile
Abstract Objective: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. Methods: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 in three centers. All the records were prospectively collected and retrospectively reviewed. Res
