Artificial intelligence in blood donor management: A narrative review

Vox Sanguinis, EarlyView.
Abstract Blood transfusions are vital in health care, yet maintaining an adequate and safe blood supply remains a significant challenge. To address blood donation–associated challenges, this review explores how integrating artificial intelligence (AI) technologies can improve donor recruitment, retention and management.

Vascular health and exercise in females throughout the lifespan: Exploring puberty, pregnancy and menopause

Experimental Physiology, EarlyView.
Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.

A Prospective Study of Adverse Events in Whole Blood and Apheresis Donors at a Tertiary Care Hospital in Western India

Global Journal of Transfusion Medicine
Background and Objectives: Blood donation is a relatively safe procedure without any discomfort; however, if any unexpected or undesirable effects, i.e., an adverse donor reaction (ADR) does occur, it should be managed promptly and efficiently.

The use of a single chamber leadless pacemaker for the treatment of cardioinhibitory vasovagal syncope

International Journal of Cardiology: Heart & Vasculature, 2019
Background: The use of pacemakers in the treatment of cardioinhibitory vasovagal syncope is controversial with a mixed message from the limited evidence base.

Children with transient loss of consciousness: Clinical characteristics and the effectiveness of diagnostic tests

Pediatrics and Neonatology, 2020
Background: Transient loss of consciousness (TLOC) is common among children and adolescents. The aims of this study were to identify clinical differences between patients with vasovagal syncope and those with epileptic seizures, which account for a large

Genetics of vasovagal syncope [PDF]

Autonomic Neuroscience, 2014
Vasovagal syncope (VVS) is the most frequent type of syncope and affects about 25% of the population. The role of genetic factors in VVS has long been debated. In this review we will discuss the current evidence that strongly suggests a major genetic component.Family aggregation studies have consistently shown that individuals with VVS more frequently ...

On‐feet isometric bracing maintains cerebral arterial blood velocity during lower body negative pressure via preload augmentation

Experimental Physiology, EarlyView.
Abstract Orthostatic stress reduces venous return and stroke volume (SV), risking cerebral hypoperfusion despite autonomic compensation. Although lower‐limb counterpressure manoeuvres improve cerebral perfusion in upright posture, their effects on cerebral blood velocity (CBV) during lower‐body negative pressure (LBNP) and the associated mechanisms are

Isoproterenol Causing Coronary Vasospasm and ST Elevations During Tilt Table Testing

Journal of Investigative Medicine High Impact Case Reports, 2020
Syncope is a sudden but reversible brief loss of consciousness secondary to an acute reduction of cerebral perfusion. Reflex syncope denotes neurologically mediated syncope, which includes vasovagal, carotid sinus syndrome, and other situational syncope.
