Development and validation of a checklist for cardiopulmonary bypass

J. extra-corpor. technol; 57 (1), 2025
INTRODUCTION: Risk prevention protocols related to patient care have been developed to reduce the incidence of adverse events in health care services. Cardiopulmonary bypass (CPB) can trigger several complications, including physiological problems, electrical, mechanical, and human failures, or defective...

Diagnostic accuracy of artificial-intelligence-based electrocardiogram algorithm to estimate heart failure with reduced ejection fraction: a systematic review and meta-analysis

Curr. probl. cardiol; 50 (4), 2025
INTRODUCTION: AI-based ECG has shown good accuracy in diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with left ventricle reduced ejection fraction (LVEF <40 %) is not yet well established. What is the ...

Three and two dimensional cardiac mechanics by speckle tracking are predictors of outcomes in chagas heart disease

ABSTRACT: Chagas disease (CD) is a neglected infectious disease associated with early mortality and substantial disability. Three-dimensional speckle tracking (3D STE) may play a role in the evaluation of CD. We aim to characterize new echocardiographic variables in patients with CD and to assess the hyp...

Como obter resultados confiáveis em cromatografia
How to obtain reliable results in chromatography

Rev. Inst. Adolfo Lutz; 60 (1), 2001
Resultados analíticos que näo tenham passado por um processo de validaçäo carecem de qualquer valor. O presente trabalho enfoca etapas algumas vezes negligenciadas em laboratórios de cromatografia e que, no entanto, säo cruciais para a obtençäo de resultados analíticos confiáveis: uso de métod...
