AI Article Synopsis
Article Abstract
Cerebral blood flow velocity (CBF-V) measured by transcranial doppler was assessed in 628 elderly individuals who had cerebral magnetic resonance imaging performed as part of a population-based study on vascular aging. Cerebral white matter hyperintensities (WMHs) were associated with low CBF-V, such as the adjusted odds ratios of severe WMHs from highest (referent) to lowest quartile of mean CBF-V were 1.0, 1.7, 3.7, and 4.3 (p = 0.001). Further, CBF-V was found to be a stronger risk factor for WMHs than high blood pressure. These findings suggest that the assessment of CBF-V might be a powerful tool in future studies on WMHs.

Objective: Arterial sampling for PET imaging often involves continuously measuring the radiotracer activity concentration in blood using an automatic blood sampling system (ABSS). We proposed and validated an external delay and dispersion correction procedure needed when a change in flow rate occurs during data acquisition. We also measured the external dispersion constant of [11C]CURB, [18F]FDG, [18F]FEPPA, and [18F]SynVesT-1.

Ischemic stroke is caused by blockage of blood vessels in brain, affecting normal function. The roles of Signal Transformer and Activator of Transcription 1 (STAT1), CASP8, and MYD88 in ischemic stroke and its care are unclear. The ischemic stroke datasets GSE16561 and GSE180470 were found from the Gene Expression Omnibus database.

Background: Digital technologies for type 2 diabetes mellitus (T2DM) care hold great potential to improve patients' health in the long term. Only a subset of telemedicine offerings are digital interventions that meet the criteria for prescribable digitale Gesundheitsanwendung (digital health apps; DiGAs) in Germany. Digital treatments further provide vast amounts of patient data that are important to generate evidence.

Objective: The pathophysiology of delayed cerebral ischemia (DCI) is not fully elucidated. The lack of accurate diagnostic tools increases the probability of delayed diagnosis and timely treatment. The authors assessed the relationship of 8-iso-prostaglandin F2α (F2-IsoP) and oxidative stress biomarkers, nitric oxide synthase 3 (NOS3) and nicotinamide adenine dinucleotide phosphate (NADPH), with DCI after aneurysmal subarachnoid hemorrhage (aSAH).
