Pulse‐based photoplethysmography quality assessment improves wearable seizure detection performance

Epilepsia Open, Volume 11, Issue 4, Page 1149-1158, August 2026.
Pulse‐based photoplethysmography quality assessment improves wearable seizure detection performance. Abstract Objective Wearable photoplethysmography (PPG) is increasingly used for seizure detection due to its ability to unobtrusively estimate heart rate (HR).

Artificial Intelligence Techniques in Cardiac Neuromodulation: Mechanisms, Applications, and Pathways to Clinical Translation

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Artificial intelligence could improve patient selection, stimulation control, and response monitoring in cardiac neuromodulation, yet direct clinical evidence remains scarce. We map available techniques onto these three challenges and argue that safe, adaptive closed‐loop control and established therapy efficacy are prerequisites for translation ...

CardiacDP: An R package for rapid automated cardiac data processing, integrating autocorrelation, a genetic algorithm, and a tracking index

Limnology and Oceanography: Methods, Volume 24, Issue 8, August 2026.
Abstract Heart rate is a popular proxy of physiological responses, but the highly complex and variable cardiac data obtained from organisms such as marine invertebrates pose a major challenge to efficient and accurate data processing. To address this, we developed a novel, integrative algorithm for rapid and automated cardiac data processing.

Obstructive Sleep Apnea: Epidemiology, Pathophysiology, Complications, Diagnosis, Management, and Emerging Fibrosis‐Linked Remodeling

MedComm, Volume 7, Issue 8, August 2026.
Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...

Toward Autonomous Clinics: Human–Robot Collaboration in Clinical Care

MedComm, Volume 7, Issue 8, August 2026.
This graphical abstract summarizes the conceptual structure of human–robot collaboration (HRC) for autonomous clinical systems. The framework is organized around a dual‐brain architecture in which a professional brain supports clinical reasoning tasks such as diagnosis, image analysis, treatment planning, and patient monitoring, while a physical brain ...

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 623-634, August 2026.
ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–
