β-Hydroxy β-Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile. [PDF]

Drug Test Anal
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

Left ventricular noncompaction cardiomyopathy and short QT syndrome due to primary carnitine deficiency

Annals of Noninvasive Electrocardiology, Volume 28, Issue 6, November 2023., 2023
A 13‐year‐old patient with palpitations and syncope was diagnosed with a rare, reversible cause of short QT syndrome (SQTS) and cardiomyopathy—primary carnitine deficiency (PCD) caused by a mutation in the SLC22A5 gene. Treatment with carnitine supplementation corrected her QT interval to within normal range, with significant improvement in ventricular

Dried blood spots for doping controls—Development of a comprehensive initial testing procedure with fully automated sample preparation

Biomedical Chromatography, Volume 37, Issue 8, August 2023., 2023
Abstract Currently, primarily urine, whole blood and serum samples are analyzed for doping‐relevant substances in professional sports, but recently dried blood spots (DBS) have been introduced as complementary matrix, offering advantageous features, e.g. a minimally invasive sampling procedure.
