13. Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting
ABSTRACT Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving the endothelium of veins during high-pressure distention. Methods: Human saphenous veins (SVs)

14. Comparison of Proseal LMA with i-Gel in children under controlled ventilation: a prospective randomised clinical study
Abstract Background: Supraglottic airway device is presently the most common modality of airway management in children for short surgical procedures. The i-gel is one such novel supraglottic airway device with a non-inflatable cuff. The objective of the present study was to evaluate the efficiency of i-gel compared to LMA Proseal regarding oropharyngeal lea

15. Functional Changes of the Upper Esophageal Sphincter in Gastroesophageal Reflux
Abstract Introduction The upper esophageal sphincter (UES) is a muscular structure located at the transition from the pharynx to the esophagus, with the cricopharyngeal muscle as the most important component. During gastroesophageal reflux, the pressure in the UES elevates, which is apparently a protective mechanism to prevent esophagopharyngeal reflux and

16. Is the Wistar Rat a more Suitable Normotensive Control for SHR to Test Blood Pressure and Cardiac Structure and Function?
Abstract Background: There are divergences in the literature regarding the experimental model (Wistar-WIS or Wistar Kyoto-WKY) to be used as a Spontaneously Hypertensive Rat (SHR) control. The characterization of these models in terms of cardiovascular parameters provides researchers with important tools at the time of selection and application in scientifi

17. Pharmaceutical Care in Primary Care: an Experience with Hypertensive Patients in the North of Brazil
Abstract Background: Uncontrolled blood pressure has been associated with poor adherence to drug treatment. Objectives: To assess blood pressure control in hypertensive patients attending primary health centers after implementation of a pharmaceutical follow-up program in a city of the north of Brazil. Methods: Observational, cross sectional, descriptive

18. Rotational Steady Waves in a Low-pressure Region
ABSTRACT Nonlinear steady rotational waves in a low-pressure region are investigated. The problem is formulated in a simplified canonical domain through the use of a conformal mapping, which flattens the free surface. Steady waves are computed numerically using a Newton’s method and classified into three types. Besides, our results indicate that there is a

20. Ring Fracture of Brazilian Aortic Valve Bioprostheses Using Non-Compliant High-Pressure Transcatheter Balloon, an Ex Vivo Test
ABSTRACT Introduction: Aortic valve bioprostheses ring fracture in valve-in-valve procedures has shown low complication rates and presents as an option in the treatment of patients at high risk for conventional surgery, avoiding high transvalvular gradients, which are associated with increased mortality. Some prostheses available in the market cannot be fra

21. Comparing CPAP masks during initial titration for Obstructive Sleep Apnea Syndrome: one-year experience
Abstract Objective: Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for OSA. A wide variety of masks are used during CPAP therapy. The aim of the study is to compare polysomnography outcomes during titration for different types of masks (oronasal, nasal and pillow) and assess the impact on PAP titration. Methods: We retrospectivel

23. Investigation of serum phoenixin levels in patients with hypertension
SUMMARY OBJECTIVE: Hypertension is a major modifiable risk factor for cardiovascular disease and premature death worldwide. Phoenixin is a newly identified neuropeptide with multiple bioactivity. However, there was no published data about phoenixin levels in hypertension. The aim of this study was to evaluate the relationship between phoenixin and hypertens

24. The dilemma of choosing obstetrics and anesthesia techniques in a patient with cerebral cavernomatosis: a case report
Abstract This report describes the case of a pregnant woman who arrived for preanesthetic assessment of External Cephalic Version (ECV) for fetus in breech presentation and cesarean section in case of ECV failure. Although the technique seems simple, attempts to rotate the fetus can result in elevated intracranial pressure, which might cause malformation ble
