Protective effect of dexmedetomidine against myocardial ischemia-reperfusion injury in rabbits

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To investigate the influence of dexmedetomidine on myocardial ischemia-reperfusion injury (IRI) in rabbits. Methods: Twenty-four New Zealand white rabbits were randomly divided into two equal-sized groups: IRI group (group IR) and dexmedetomidine group (group D). Systolic blood pres...

Influence of biomaterials on scintigraphic diagnosis of periprosthetic infections. Ceftizoxime-99m technetium model

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To compare the influence of two metallic implants in the diagnosis of periprosthetic infection using 99m technetium-labeled ceftizoxime. Methods: Twenty rats were randomly divided into four groups, which received sterile and contaminated titanium and stainless steel implants. After 3...

The protective effect of dexmedetomidine in a rat ex vivo lung model of ischemia-reperfusion injury

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To investigate the effect of dexmedetomidine (Dex) in a rat ex vivo lung model of ischemia-reperfusion injury. Methods: An IL-2 ex vivo lung perfusion system was used to establish a rat ex vivo lung model of ischemia-reperfusion injury. Drugs were added to the perfusion solution for r...

Sensibilidad diagnóstica de electroforesis de proteínas y cadenas livianas libres séricas en gammapatías monoclonales

Rev. méd. Chile; 146 (1), 2018
Background: International guidelines suggest a screening panel for monoclonal gammopathies that contains serum protein electrophoresis (SPE), free light chain (FLC) measurements and immunofixation. This combination provides the possibility of a timely accurate diagnosis. Aim: To evaluate the sensibility...

Development and Psychometric Validation of HIPER-Q to Assess Knowledge of Hypertensive Patients in Cardiac Rehabilitation

Arq. bras. cardiol; 110 (1), 2018
Abstract Background: The absence of instruments capable of measuring the level of knowledge of hypertensive patients in cardiac rehabilitation programs about their disease reflects the lack of specific recommendations for these patients. Objective: To develop and validate a questionnaire to evaluate th...

Correlation of Electrocardiographic Changes with Cardiac Magnetic Resonance Findings in Patients with Hypertrophic Cardiomyopathy

Arq. bras. cardiol; 110 (1), 2018
Abstract Background: Electrocardiogram is the initial test in the investigation of heart disease. Electrocardiographic changes in hypertrophic cardiomyopathy have no set pattern, and correlates poorly with echocardiographic findings. Cardiac magnetic resonance imaging has been gaining momentum for bette...

Prognostic Accuracy of the GRACE Score in Octogenarians and Nonagenarians with Acute Coronary Syndromes

Arq. bras. cardiol; 110 (1), 2018
Abstract Background: The GRACE Score was derived and validated from a cohort in which octogenarians and nonagenarians were poorly represented. Objective: To test the accuracy of the GRACE score in predicting in-hospital mortality of very elderly individuals with acute coronary syndromes (ACS). Methods...

A Brazilian-Portuguese version of the Kinesthetic and Visual Motor Imagery Questionnaire

Arq. neuropsiquiatr; 76 (1), 2018
ABSTRACT Motor imagery has emerged as a potential rehabilitation tool in stroke. The goals of this study were: 1) to develop a translated and culturally-adapted Brazilian-Portugese version of the Kinesthetic and Visual Motor Imagery Questionnaire (KVIQ20-P); 2) to evaluate the psychometric characteristic...
