AI-Based Estimation of End-Systolic Elastance From Arm-Pressure and Systolic Time Intervals

Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou

Left ventricular end-systolic elastance (Ees) is a major determinant of cardiac systolic function and ventricular-arterial interaction. Previous methods for the Ees estimation require the use of the echocardiographic ejection fraction (EF). However, given ...

Acute and Long-Term Effects of Aortic Compliance Decrease on Central Hemodynamics: A Modeling Analysis

Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou

Aortic compliance is an important determinant of cardiac afterload and a contributor to cardiovascular morbidity. In the present study, we sought to provide in silico insights into the acute as well as long-term effects of aortic compliance decrease on cen ...

Early sepsis diagnosis via protein and miRNA biomarkers using a novel point-of-care photonic biosensor

Hatice Altug, Alexander Belushkin

y Sepsis is a condition characterized by a severe stage of blood-infection often leading to tissue damage, organ failure and finally death. Fast diagnosis and identification of the sepsis stage (sepsis, severe sepsis or septic shock) is critical for the pa ...

Analysis of morphological and haemodynamical indexes in abdominal aortic aneurysms as preliminary indicators of intraluminal thrombus deposition

Alfio Quarteroni, Simone Deparis, Claudia Maria Colciago

In this paper we study the correlation between the Wall Shear Stress (WSS), a haemodynamical index derived from numerical simulations, and an new index MFA-ILT for the characterisation of intraluminal thrombus (ILT) in presence of abdominal aortic aneurysm ...

The therapeutic role of NAD+ modulation in fatty liver disease

Karim Laurent Gariani

NAFLD encompasses a disease spectrum ranging from hepatic steatosis to nonalcoholic steatohepatitis (NASH), fibrosis, and finally cirrhosis, which predisposes to the development of hepatocellular carcinoma. With no approved pharmacological treatment, NAFLD ...

Platinum nanopetal-based potassium sensors for acute cell death monitoring

Giovanni De Micheli, Sandro Carrara, Irene Taurino

Growing interest in the role of ions as cell death regulators has led to the consideration of K+, which plays a major role in events such as necrosis, apoptosis and osmotic shock. These mechanisms induce effluxes of K+, which can be m ...

Accuracy of commercial devices and methods for noninvasive estimation of aortic systolic blood pressure a systematic review and meta-analysis of invasive validation studies

Nikolaos Stergiopoulos, Thomas Alois Weber

Background: Although compelling evidence has established the physiological and clinical relevance of aortic SBP (a-SBP), no consensus exists regarding the validity of the available methods/techniques that noninvasively measure it. Objectives: The systemati ...

A shock front at the radio relic of Abell 2744

Jean-Paul Richard Kneib, Mathilde Jauzac, Céline Tchernin

Radio relics are Mpc-scale diffuse radio sources at the peripheries of galaxy clusters which are thought to trace outgoing merger shocks. We present XMM-Newton and Suzaku observations of the galaxy cluster Abell 2744 (z = 0.306), which reveal the presence ...

Neuroenergetic Response to Prolonged Cerebral Glucose Depletion after Severe Brain Injury and the Role of Lactate

Pierre Magistretti, Jocelyne Bloch, Luc Pellerin

Lactate may represent a supplemental fuel for the brain. We examined cerebral lactate metabolism during prolonged brain glucose depletion (GD) in acute brain injury (ABI) patients monitored with cerebral microdialysis (CMD). Sixty episodes of GD (defined a ...

First in vivo application and evaluation of a novel method for non-invasive estimation of cardiac output

Nikolaos Stergiopoulos, Orestis Vardoulis

Surgical or critically ill patients often require continuous assessment of cardiac output (CO) for diagnostic purposes or for guiding therapeutic interventions. A new method of non-invasive CO estimation has been recently developed, which is based on press ...
