Acute effect of lower‐limb peristaltic pulse external pneumatic compression on segmental arterial stiffness in healthy young adults

Physiological Reports, Volume 13, Issue 10, May 2025.
Abstract Although an acute bout of peristaltic pulse external pneumatic compression (EPC) of the lower extremities can improve vascular function, its effect on arterial stiffness remains unclear. This study aimed to investigate the acute effect of lower‐limb peristaltic pulse EPC on segmental arterial stiffness.

Triple Björk-Shiley valve: More than 30 years of asymptomatic functioning: To the memory of late academic Prof. Isidor Papo and the 45th anniversary of the first valve implantation in Yugoslavia [PDF]

, 2010
Introduction. The Björk-Shiley Delrin (BSD) tilting disc heart valve was first clinically used in 1969. A triple BSD valve replacement has not been quite common, because of high postoperative risk and complications, but there have been several cases with

Wearable Single‐Electrode Capacitive Sensor with Large Penetration Depth for Intelligent Deep Tissue and Hemorrhage Monitoring

Advanced Sensor Research, Volume 4, Issue 2, February 2025.
Monitoring deep tissue biometrics is crucial for managing internal hemorrhage. This study introduces a novel single‐electrode capacitive sensor using carbon nanotube composites to improve penetration depth and sensitivity to regional dielectric or pressure changes.

A Comprehensive Nomogram Integrating Phonocardiogram and Echocardiogram Features for the Diagnosis of Heart Failure With Preserved Ejection Fraction

Clinical Cardiology, Volume 47, Issue 11, November 2024.
A total of 204 patients and 49 features were collected. After splitting the population into training and test sets according to a ratio of 7:3, the LASSO and logistic regression was used to select the final five factors for a nomogram. The AUC for the nomogram model is 0.945, while the AUC for the echocardiographic parameters combined with NT‐proBNP in

PhonoSys: Mobile Phonocardiography Diagnostic System for Newborns

EAI Endorsed Transactions on Mobile Communications and Applications, 2016
Heart murmurs have been found to be a life threatening condition for the newborns who are born with cardiac abnormalities. The first sign of pathological changes of heart valves appears in phonocardiogram which contains very useful information about ...

Learning technology in health professions education: Realising an (un)imagined future

Medical Education, Volume 58, Issue 1, Page 36-46, January 2024.
Abstract Context Technology is being introduced, used and studied in almost all areas of health professions education (HPE), often with a claim of making HPE better in one way or another. However, it remains unclear if technology has driven real change in HPE.

Time-frequency scaling transformation of the phonocardiogram based of the matching pursuit method.

, 1998
International audienceA time-frequency scaling transformation based on the matching pursuit (MP) method is developed for the phonocardiogram (PCG). The MP method decomposes a signal into a series of time-frequency atoms by using an iterative process. The

Passive Fetal Monitoring by Advanced Signal Processing Methods in Fetal Phonocardiography

IEEE Access, 2020
Fetal phonocardiography (fPCG) is a non-invasive technique for detection of fetal heart sounds (fHSs), murmurs and vibrations. This acoustic recording is passive and provides an alternative low-cost method to ultrasonographic cardiotocography (CTG ...
