Modulatory neurotransmitters exert powerful control over neurons and the brain vasculature. Gamma Entrainment Using Sensory Stimuli (GENUS) promotes amyloid clearance via increased perivascular cerebral spinal fluid (CSF) flux in mouse models of Alzheimer's Disease. Here we use whole-brain activity mapping to identify the cholinergic basal forebrain as a key region responding to GENUS.

Article Synopsis
  • The study compares aortic valve calcification (AVC) indexed to the aortic annulus area (AA) using Doppler echocardiography and multidetector computed tomography in patients with aortic stenosis (AS).
  • Data from 889 mainly White patients showed that using AVCd measures provides stronger correlations with hemodynamic variables and better predictive outcomes for all-cause mortality compared to traditional AVC measures.
  • AVCd ratio thresholds for identifying severe AS were established at 334 Agatston units for women and 467 for men, with AVCd proving superior in predicting survival under medical treatment across various patient subgroups.

Valvular heart diseases (VHDs) are a major cause of cardiovascular morbidity and mortality worldwide. As degenerative and functional mechanisms represent the main etiologies in high-income countries are degenerative and functional, while in low income countries etiologie is mostly rheumatic. Although therapeutic options have evolved considerably in recent years, women are consistently diagnosed at later stages of their disease, are delayed in receiving surgical referrals, and exhibit worse postoperative outcomes, compared to men.

Patients with cancer undergoing chemotherapy frequently experience a neurological condition known as chemotherapy-related cognitive impairment, or "chemobrain," which can persist for the remainder of their lives. Despite the growing prevalence of chemobrain, both its underlying mechanisms and treatment strategies remain poorly understood. Recent findings suggest that chemobrain shares several characteristics with neurodegenerative diseases, including chronic neuroinflammation, DNA damage, and synaptic loss.
