Cerebral Blood Flow in Mild Cognitive Impairment and Dementia: A Systematic Review and Meta- Analysis of Transcranial Doppler Studies

Cerebral Circulation - Cognition and Behavior
Introduction: Reduced cerebral blood flow has been associated with cognitive decline and incident dementia, with oxidative stress and reduced beta-amyloid clearance as possible mechanisms for neurodegeneration.

Analysis of the Navigation of Magnetic Microrobots through Cerebral Bifurcations for Targeted Drug Delivery

Advanced Intelligent Systems, EarlyView.
The motion of magnetic microrobots through cerebral bifurcations depends on various parameters such as the microrobots size, the blood velocity, and the imposed magnetic field gradients, among others. This work presents an in‐depth analysis of the effects of these parameters and equations predicting the required magnetic gradients based on the ...

Enhanced Embolic Signal Analysis through Ensemble Deep Learning Techniques Utilizing Transfer Learning and Layer Freezing Strategies

Advanced Intelligent Systems, EarlyView.
A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Characterizing the Healthcare Utilization and Costs of Hereditary Hemorrhagic Telangiectasia

American Journal of Hematology, EarlyView.
ABSTRACT Hereditary hemorrhagic telangiectasia (HHT) is the second‐most common inherited bleeding disorder worldwide, afflicting one in 4000–5000 people, and is the most morbid inherited bleeding disorder of women. HHT causes recurrent severe epistaxis, chronic gastrointestinal bleeding, heavy menstrual bleeding, and arteriovenous malformations in the ...
