Outflow tract ventricular arrhythmias (OT-VA) are common in healthy subjects without structural heart disease (SHD), and generally considered benign. However, athlete-specific data on the clinical meaning of different arrhythmia (VA) morphologies scarce. To assess prevalence SHD as well long-term sports medicine outcomes a cohort athletes with OT-VA undergoing comprehensive diagnostic assessmen...

BACKGROUND Assessment of women veterans' health needs and preferences and their care environment have been identified as a priority research need by the national Veterans Affairs (VA) Women's Health research agenda. Our objective was to identify women veterans' health care preferences and perceptions associated with sole or dual VA health care use. METHODS This cross-sectional study of 1,002 ...

This work introduces an automatic procedure for determining the size of regression class trees for individual speakers using an ensemble of speaker-level features to control the number of transformations, if any, that should be estimated by maximum likelihood linear regression. Experiments with a state-of-the-art speech recognition system that uses this procedure show improvements in word error...

Many questions remain regarding vitamin A (VA) supplementation of infants. Herein we compared direct oral VA supplementation of the neonate and indirect treatment through maternal dietary VA (M-VA) treatment on VA status and kinetics in neonatal rats. Treatments included direct VA combined with retinoic acid (RA) [D-VARA; VA (6 mg/kg) + 10% RA, given orally to neonates on postnatal day (P)2 and...

PURPOSE To determine photopic and mesopic distance high-contrast visual acuity (HC-VA) and low-contrast visual acuity (LC-VA) in eyes with early age-related macular degeneration (AMD). METHODS Measurements were made in 22 subjects with early AMD and 28 healthy control subjects. Inclusion criteria included a photopic HC-VA of 20/25 or better. Distance VA was measured using HC (96%) and LC (10%...

Extracts of Viscum album (VA); a semi-parasitic plant, are frequently used in the complementary therapy of cancer and other immunological disorders. Various reports show that VA modulates immune system and exerts immune-adjuvant activities that might influence tumor regression. Currently, several therapeutic preparations of VA are available and hence an insight into the mechanisms of action of ...

OBJECTIVES We administered pilsicainide chloride, a class Ic pure sodium channel blocker, to patients with Brugada syndrome (BS) and evaluated the occurrence of ventricular arrhythmia (VA) and T-wave alternans (TWA). BACKGROUND Ventricular arrhythmia and TWA are sometimes induced by a sodium channel blocker challenge test in BS patients, but the significance of the induced VA and TWA is not k...
