The Impact of Vascular Risk Factors on Cerebral Amyloid Angiopathy: A Cohort Study in Hereditary Cerebral Amyloid Angiopathy and a Systemic Review in Sporadic Cerebral Amyloid Angiopathy.

Introduction: Cerebral amyloid angiopathy (CAA) has a remarkably variable disease course, even in monogenetic hereditary forms. Our aim was to investigate the prevalence of vascular risk factors and their effect on disease onset and course in Dutch-type hereditary (D-)CAA and sporadic CAA.

Methods: We performed a cohort study in D-CAA to investigate the association between vascular risk factors (hypertension, hypercholesterolemia, smoking, and alcohol use) and age of intracerebral hemorrhage (ICH) onset and time of ICH recurrence with survival analyses.

Effects of GLPG3970 on Sulfasalazine and Methotrexate Pharmacokinetics in Healthy Adults: Two Open-Label, Phase I, Drug-Drug Interaction Studies.

GLPG3970 is a selective salt-inducible kinase 2/3 inhibitor intended for the treatment of inflammatory diseases. In vitro studies suggest GLPG3970 strongly inhibits breast cancer resistance protein (BCRP), indicating a possible interaction with BCRP substrates such as sulfasalazine (SSZ; a probe substrate for intestinal BCRP inhibition) and methotrexate (MTX), both inflammatory disease medications. Two open-label, nonrandomized, phase I, drug-drug interaction (DDI) studies assessed the pharmacokinetics of SSZ 1,000 mg (NCT04720183) and MTX 7.

Photocatalytic Degradation of Bacterial Lipopolysaccharides by Peptide-Coated TiO Nanoparticles.

In this study, we report the degradation of smooth and rough lipopolysaccharides (LPS) from Gram-negative bacteria and of lipoteichoic acid (LTA) from Gram-positive bacteria by peptide-coated TiO nanoparticles (TiO NPs). While bare TiO NPs displayed minor binding to both LPS and LTA, coating TiO NPs with the antimicrobial peptide LL-37 dramatically increased the level of binding to both LPS and LTA, decorating these uniformly. Importantly, peptide coating did not suppress reactive oxygen species generation of TiO NPs; hence, UV illumination triggered pronounced degradation of LPS and LTA by peptide-coated TiO NPs.

Quantitative electroencephalography in cerebral amyloid angiopathy.

Objective: We investigated whether quantitative electroencephalography (qEEG) correlates with cognition and cortical superficial siderosis (cSS) in cerebral amyloid angiopathy.

Methods: We included patients with sporadic (sCAA) and hereditary Dutch-type CAA (D-CAA). Spectral measures and the phase lag index (PLI) were analyzed on qEEG.
