Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

Analysis and Characterization of Kisspeptin and Its Analogues in Serum and Urine Samples by Liquid Chromatography–High‐Resolution Mass Spectrometry for Doping Control Purposes

Drug Testing and Analysis, EarlyView.
Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Comparison of Dried Blood Spot Sampling Methods for RNA‐Based Biomarker Measurement in Anti‐Doping

Drug Testing and Analysis, EarlyView.
This study demonstrates that RNA‐based biomarkers of erythropoiesis, ALAS2 and CA1, can be reliably quantified across commonly used DBS sampling matrices, including venous and capillary blood spotted on cellulose cards and the Tasso‐M20 device. ABSTRACT Dried blood spot (DBS) sampling offers logistical advantages, but it remains unexplored whether ...

Elimination Profile of Deflazacort and Metabolites in Urine and Plasma Following Oral Administration: Relevance to Sports Drug Testing

Drug Testing and Analysis, EarlyView.
Results confirm that the MRL of 30 ng/mL for 21‐desacetyl‐deflazacort together with a 3‐day washout period is an appropriated strategy to detect oral deflazacort administration in sport competition. ABSTRACT Deflazacort (DEF) is a glucocorticoid prohibited in sports competitions when orally administered.

Investigations Into the Metabolism and Elimination of Flmodafinil and Fladrafinil for Sports Drug Testing Purposes

Drug Testing and Analysis, EarlyView.
This article investigates the metabolism and elimination of flmodafinil and fladrafinil, two fluorinated analogs of modafinil and adrafinil listed as S6 stimulants by the World Anti‐Doping Agency. After single‐dose administration to six volunteers, the compounds and their main metabolites were studied in urine and blood.

“I Was Just Like a Sponge, Absorbing All the Wrong Information”: Examining the Role of Social Media in Athletes' Eating Disorder and Recovery Experiences

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Within sport environments, athletes are exposed to norms that circulate narrow meanings about the body and food, contributing to the high prevalence of eating disorders (EDs). While social media can support ED recovery, it can also further constrain food‐ and body‐related messages for athletes.
