Research progress on the depth of anesthesia monitoring based on the electroencephalogram

Ibrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Effects of descending aortic occlusion for massive obstetric hemorrhage: Nationwide analysis of maternal death in Japan

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To evaluate the effects of aortic occlusion (AO) on severe postpartum hemorrhage (PPH)—a leading cause of preventable maternal mortality—using a nationwide maternal death registry in Japan. Methods A nationwide retrospective observational study of hemorrhage‐related maternal deaths was conducted in Japan between 2010 and 2024 ...

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

Portal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Shear‐Responsive Red Blood Cell Carriers for Targeted Drug Delivery to Constricted Arteries

Small, EarlyView.
Red blood cells are harnessed as mechanoresponsive carriers that exploit the elevated shear stress of stenotic arteries to transiently open membrane pores and release encapsulated therapeutics selectively at sites of arterial narrowing. By coupling vascular hemodynamics with RBC membrane mechanics, a hemodynamically activated platform for localized ...
