Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Amyloid‐β–Related Cortical Susceptibility Alterations in Individuals Under Assessment for Alzheimer's Disease: A χ‐Separation Study

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Assessment of amyloid‐β (Aβ) burden and associated iron deposition and neurodegeneration is important for Alzheimer's disease (AD) management. Although quantitative susceptibility mapping (QSM) detects iron and myelin changes, conventional metrics suffer from signal cancelation between paramagnetic and diamagnetic components ...

Structural Covariance Analysis of Altered Brain Development in Neonates With Congenital Heart Disease After Surgery

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Brain development is altered in neonates with congenital heart disease (CHD), with well‐characterised reductions in regional brain volumes and enlargement of CSF spaces. However, perioperative morphological changes remain incompletely understood. Purpose To identify brain regions showing spatial patterns of coordinated expansion and

Metabolic Syndrome and Dementia Risk in Older Adults: A Narrative Review

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Dementia is a major global health issue in aging societies. Metabolic syndrome (MetS), a cluster of metabolic abnormalities, has been proposed as a modifiable risk factor for dementia, although existing evidence remains inconsistent. This review examined recent studies on the association between MetS and dementia risk in older adults.
