Comparison of methods to determine the lactate threshold during leg press exercise in long-distance runners

Motriz (Online); 26 (2), 2020
Abstract Aims: To determine lactate threshold (LT) by three different methods (visual inspection, algorithmic adjustment, and Dmax) during an incremental protocol performed in the leg press 45° and to evaluate correlation and agreement among these different methods. Methods: Twenty male long-distance ...

Implementation of an Artificial Intelligence Algorithm for sepsis detection

Rev. bras. enferm; 73 (3), 2020
ABSTRACT Objectives: to present the nurses' experience with technological tools to support the early identification of sepsis. Methods: experience report before and after the implementation of artificial intelligence algorithms in the clinical practice of a philanthropic hospital, in the first half of ...

Definiciones operativas y protocolo anestésico durante la pandemia producida por SARS-CoV-2 en un programa de cirugía cardíaca pediátrica

Rev chil anest; 49 (3), 2020
The clinical characteristics of the pediatric population infected with the SARS-CoV-2 virus in general are not as severe as in the adult population, so they can be considered asymptomatic carriers. The pediatric patient with congenital heart disease are considered a high risk group of contagion in the SA...

Hepatotoxicidad grave inducida por sertralina

Gastroenterol. latinoam; 31 (2), 2020
We report the case of a 19-year-old patient, with a history of traumatic liver damage, but with a normal liver profile at her first discharge; 1 month after the event, with post-traumatic stress disorder, treatment with 25 mg of sertraline was started every day; one month later, she develops severe hepat...

Artificial intelligence algorithm for the histopatological diagnosis of skin cancer

Clin. biomed. res; 40 (4), 2020
Introduction: Cutaneous neoplasms are the most common cancers in the world, and have high morbidity rates. A definitive diagnosis can only be obtained after histopathological evaluation of the lesions. To develop an artificial intelligence program to establish the histopathological diagnosis of cutaneous...

Automatic segmentation of brain tumors in magnetic resonance imaging

ABSTRACT Objective To develop a computational algorithm applied to magnetic resonance imaging for automatic segmentation of brain tumors. Methods A total of 130 magnetic resonance images were used in the T1c, T2 and FSPRG T1C sequences and in the axial, sagittal and coronal planes of patients with brai...

A neural network for prediction of risk of nosocomial infection at intensive care units: a didactic preliminary model

ABSTRACT Objective: To propose a preliminary artificial intelligence model, based on artificial neural networks, for predicting the risk of nosocomial infection at intensive care units. Methods: An artificial neural network is designed that employs supervised learning. The generation of the datasets wa...

Cinematic rendering for three-dimensional reconstructions of the chest wall: a new reality

ABSTRACT Computed tomography with multiple detectors and the advancement of processors improved rendered images and three-dimensional reconstructions in clinical practice. Traditional axial slices form non-intuitive images because they are seen in only one plane. The three-dimensional reconstructions can...

Fluid and hemodynamic management in hemodialysis patients: challenges and opportunities

J. bras. nefrol; 41 (4), 2019
Abstract Fluid volume and hemodynamic management in hemodialysis patients is an essential component of dialysis adequacy. Restoring salt and water homeostasis in hemodialysis patients has been a permanent quest by nephrologists summarized by the 'dry weight' probing approach. Although this clinical appro...
