Associations of Central Arterial Stiffness With Brain White Matter Integrity and Gray Matter Volume in MRI Across the Adult Lifespan

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
Background Central arterial stiffening is associated with brain white matter (WM) damage and gray matter (GM) volume loss in older adults, but little is known about this association from an adult lifespan perspective. Purpose To investigate the associations of central arterial stiffness with WM microstructural organization, WM lesion load, cortical ...

Effect of Body Position on Dynamic Apparent Diffusion Coefficient Changes During the Cardiac Cycle in the Human Brain

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dynamic changes in the apparent diffusion coefficient (ΔADC) during the cardiac cycle reflect water molecule fluctuations in the brain and intracranial conditions. While body position strongly affects intracranial conditions, the relationship between ΔADC and body position has been less explored, as conventional MRI is typically ...

Deadline Effect in Stroke Patient Care: A Temporal Motivation Theory Perspective of Process Management

open access: yesJournal of Operations Management, EarlyView.
ABSTRACT Stroke is a highly time‐sensitive medical emergency, and earlier treatment is crucial. Drawing on Temporal Motivation Theory, we investigate a “deadline effect” in stroke care and analyze how two deadlines, that is, a medically oriented one (administering Tissue Plasminogen Activator, TPA, within 4.5 h of symptom onset) and a goal‐oriented one
