Massive transfusion practices and low‐titer group O whole blood utilization before and after implementation in a low‐volume level I trauma center: A six‐year review

open access: yesTransfusion, EarlyView.
Abstract Background Low‐titer O whole blood (LTOWB) has been increasingly incorporated into trauma resuscitation and massive transfusion protocols (MTPs). Recent randomized trials have not demonstrated superiority of prehospital LTOWB over component‐based resuscitation, while the utilization and sustainability of LTOWB programs, particularly in low ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

open access: yesExperimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Thermo‐tone: A newly revealed mechanism of blood flow regulation

open access: yesExperimental Physiology, EarlyView.
Abstract Myogenic tone enables dynamic control of tissue blood flow. This intrinsic property of vascular smooth muscle cells to sense stretch and reflexively adjust the calibre of small arteries is crucial to maintain capillary pressure and a blood flow reserve. For over 120 years blood pressure was considered the sole determinant of myogenic tone. Our
