Application of machine learning to automated analysis of cerebral edema in large cohorts of ischemic stroke patients [PDF]

, 2018
Cerebral edema contributes to neurological deterioration and death after hemispheric stroke but there remains no effective means of preventing or accurately predicting its occurrence. Big data approaches may provide insights into the biologic variability

The ultrasonic cardiac output monitor (USCOM) as a tool in evaluating fluid responsiveness in pediatric patients underwent emergency surgery

Bali Journal of Anesthesiology, 2019
Background: Assessment fluid adequacy in pediatric patients underwent surgery is a challenge for anesthesiologists. Hemodynamic parameters used as fluid monitoring sometimes don't accurately provide valid information.

Lower Ipsilateral Hippocampal Integrity after Ischemic Stroke in Young Adults: A Long-Term Follow-Up Study.

PLoS ONE, 2015
Background and purposeMemory impairment after stroke is poorly understood as stroke rarely occurs in the hippocampus. Previous studies have observed smaller ipsilateral hippocampal volumes after stroke compared with controls.

Hyperglycaemia does not increase perfusion deficits after focal cerebral ischaemia in male Wistar rats [PDF]

, 2018
Background: Hyperglycaemia is associated with a worse outcome in acute ischaemic stroke patients; yet the pathophysiological mechanisms of hyperglycaemia-induced damage are poorly understood.

Brain lesion volume and capacity for consent in stroke trials: potential regulatory barriers to the use of surrogate markers [PDF]

, 2008
<p><b>Background and Purpose:</b> European directives and legislation in some countries forbid inclusion of subjects incapable of consent in research if recruitment of patients capable of consent will yield similar results.

Improvement of Left Ventricular Ejection Time Measurement in the Impedance Cardiography Combined with the Reflection Photoplethysmography

Sensors, 2018
Cardiac stroke volume (SV) is an essential hemodynamic indicator that can be used to assess whether the pump function of the heart is normal. Non-invasive SV measurement is currently performed using the impedance cardiography (ICG).
