Novel theory and potential applications of central diastolic pressure decay time constant
Nikolaos Stergiopoulos, Georgios Rovas, Sokratis Anagnostopoulos, Vasiliki Bikia, Patrick Segers
Central aortic diastolic pressure decay time constant ( ) is according to the two-element Windkessel model equal to the product of total peripheral resistance (R) times total arterial compliance (C ). As such, it is related to arterial stiffness, which has ...
2024KID-PPG: Knowledge Informed Deep Learning for Extracting Heart Rate from a Smartwatch
David Atienza Alonso, José Angel Miranda Calero, Jonathan Dan, Christodoulos Kechris
Accurate extraction of heart rate from photoplethysmography (PPG) signals remains challenging due to motion artifacts and signal degradation. Although deep learning methods trained as a data-driven inference problem offer promising solutions, they often un ...
2024Reduced order modeling of parametrized pulsatile blood flows: Hematocrit percentage and heart rate
This paper numerically evaluates the accuracy and performance of a stabilized finite element Reduced Order Modelling (ROM) approach that is designed to simulate pulsatile blood flows. The method is able to estimate fluid flow parametric solutions of intere ...
PERGAMON-ELSEVIER SCIENCE LTD2023Physiological Demands of Exergames in Older Adults- A Systematic Literature Review
New approaches are needed to address low physical activity levels among older adults and to promote daily physical activity tailored to their interests and abilities. This study aimed to review the current literature analyzing the physiological demands of ...
HUMAN KINETICS PUBL INC2023Effect of the structural modification of Candesartan with Zinc on hypertension and left ventricular hypertrophy
Nikolaos Stergiopoulos, Augusto Martins Lima, Valeria Romina Martinez
Hypertension is the most common cause of left ventricular hypertrophy, contributing to heart failure progression. Candesartan (Cand) is an angiotensin receptor antagonist widely used for hypertension treatment. Structural modifications were previously perf ...
ELSEVIER2023Uncovering personalized glucose responses and circadian rhythms from multiple wearable biosensors with Bayesian dynamical modeling
Felix Naef, Nicholas Edward Phillips
Wearable biosensors and smartphone applications can measure physiological variables over multiple days in free-living conditions. We measure food and drink ingestion, glucose dynamics, physical activity, heart rate (HR), and heart rate variability (HRV) in ...
CELL PRESS2023Multisensing wearables for real-time monitoring of sweat electrolyte biomarkers during exercise and analysis on their correlation with core body temperature
Danick Briand, Silvia Demuru, Jaemin Kim, Brince Paul Kunnel, Vincent Gremeaux, Shu Wang
Sweat secreted by the human eccrine sweat glands can provide valuable biomarker information during exercise. Real-time non-invasive biomarker recordings are therefore useful for evaluating the physiological conditions of an athlete such as their hydration ...
2023Cardiac output estimated from an uncalibrated radial blood pressure waveform: validation in an in-silico-generated population
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia
Background: Cardiac output is essential for patient management in critically ill patients. The state-of-the-art for cardiac output monitoring bears limitations that pertain to the invasive nature of the method, high costs, and associated complications. Hen ...
FRONTIERS MEDIA SA2023Towards a Framework for Estimation of User Susceptibility to Cybersickness
Cybersickness still poses a significant challenge to the widespread usage of virtual reality (VR), leading to different levels of discomfort and potentially breaking the immersive experience. Researchers have attempted to discover the possible fundamental ...
EPFL2023p-Aminobenzamidine attenuates cardiovascular dysfunctions in spontaneously hypertensive rats
Nikolaos Stergiopoulos, Fabiana Pereira Da Costa Fraga, Allancer Divino De Carvalho Nunes
Aims:Diminazene aceturate, a putative ACE2 activator, is susceptible to cleavage resulting in the formation of paminobenzamidine (PAB). This study aimed to investigate the effects of PAB in addressing cardiovascular dysfunctions in spontaneously hypertensi ...
