Agreement between invasive and oscillometric blood pressure measurements during controlled haemorrhage in anaesthetised horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Defining the reliability of oscillometry (NIBP) for measuring mean arterial pressure (MAP) during normotension and hypovolaemic hypotension could help with cardiovascular monitoring and management in horses anaesthetised in dorsal recumbency.

Body‐integrated photonic biosensors: Illuminating the path to active healthcare

open access: yesFlexMat, EarlyView.
Body‐integrated photonic biosensors are promising tools for active healthcare. These optical devices can be worn, implanted, or swallowed to monitor health signals continuously. This review introduces key sensing modalities, including fluorescence, colorimetry, SPR, LSPR, SERS, and light‐modulating materials.

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 ...

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
