Role of pain and anxiety in mediating relationships between donation history and vasovagal reaction symptoms in blood donors in England

Transfusion, EarlyView.
Abstract Background Vasovagal reactions (VVRs; faintness or fainting) can harm donor health and retention. Higher VVR rates are often observed in first‐time donors and donors with VVR histories. We quantified associations between donation history (including donation experience, donation frequency, and VVR history) and VVR symptom reports in donors in ...

Machine Learning Model Using Heart Rate Variability for the Prediction of Vasovagal Syncope

IEEE Access
Vasovagal syncope is a reversible condition that can cause serious events, such as cerebral hemorrhage. Predicting its occurrence is challenging; thus, this study aimed to develop machine learning models that use heart rate variability to predict the ...

Vasovagal oscillations and vasovagal responses produced by the Vestibulo-Sympathetic Reflex in the rat

Frontiers in Neurology, 2014
Sinusoidal galvanic vestibular stimulation (sGVS) induces oscillations in blood pressure (BP) and heart rate (HR) i.e., vasovagal oscillations, and decreases in BP and HR i.e., vasovagal responses, in isoflurane-anesthetized rats.

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 ...

Experience of blood donation and return for subsequent donation among new and repeat donors

Transfusion, EarlyView.
Abstract Background Understanding factors that influence return for subsequent donation in new compared to repeat blood donors is essential to recruiting and maintaining the blood donor base. Study Design and Methods The current research assessed self‐reported attitudes, social norms, perceived behavioral control, intentions to donate, experiences ...

Structural heart disease as the cause of syncope

Brazilian Journal of Medical and Biological Research, 2018
We described the clinical evolution of patients with structural heart disease presenting at the emergency room with syncope. Patients were stratified according to their syncope etiology and available scores for syncope prognostication.

Twenty-Four-Hour Urinary Sodium Excretion Predicts Therapeutic Effectiveness of Oral Rehydration Saline in Pediatric Vasovagal Syncope

Children, 2022
The study was designed to explore whether 24-hour urinary sodium excretion could predict the therapeutic effectiveness of oral rehydration saline in pediatric cases of vasovagal syncope.

Etiological diagnosis, prognostic significance and role of electrophysiological study in patients with Brugada ECG and syncope. [PDF]

, 2017
BACKGROUND: Syncope is considered a risk factor for life-threatening arrhythmias in Brugada patients. Distinguishing a benign syncope from one due to ventricular arrhythmias is often difficult, unless an ECG is recorded during the episode.

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.
