Preclinical, Multi-Aspect Assessment of the Reliability of a Photoplethysmography-Based Telemonitoring System to Track Cardiovascular Status

Applied Sciences, 2020
Telemonitoring systems equipped with photoplethysmography-based contour analysis of the digital arterial volume pulse (DVP) can be optimal tools for remote monitoring of cardiovascular patients; however, the method is known to be sensitive to errors.

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Continuous Wrist‐Derived Heart Rate Correlates With mYPAS Scores and Detects Between‐Assessment Heart‐Rate Elevations in Children: A Feasibility Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Perioperative anxiety affects most children undergoing surgery and predicts emergence delirium, postoperative pain, and behavioral change. The validated modified Yale Preoperative Anxiety Scale (mYPAS) is scored at only a few discrete timepoints, leaving physiologic status between assessments unmeasured.
