Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Incidental Detection of Portal Venous Gas During POCUS in a Neonate With Necrotizing Enterocolitis and Intestinal Perforation: A Case Report

Journal of Clinical Ultrasound, EarlyView.
Point‐of‐care ultrasound performed at the bedside identified hepatic portal venous gas in a critically ill neonate, prompting urgent evaluation and revealing intestinal perforation due to necrotizing enterocolitis. This case highlights the potential of POCUS to accelerate diagnosis when clinical signs are subtle or nonspecific.

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

Journal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.
