Impact of Drone Versus Car Transport on Anti‐Doping Sample Integrity Over Short Distances: A Proof‐Of‐Concept Study

Drug Testing and Analysis, EarlyView.
This proof‐of‐concept study evaluated the impact of short‐distance drone transport on anti‐doping sample integrity compared with traditional car transport. Targeted assays and untargeted metabolomics revealed equivalent biological profiles between methods, confirming that drone delivery preserves sample integrity for the athlete biological passport ...

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

Drug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...

Feeling Better Before, Not After: An Ecological Momentary Assessment of Affect Around Exercise in Women With Eating Disorders

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Maladaptive exercise includes excessive, compulsive, or compensatory exercise and is a common eating‐disorder (ED) symptom associated with increased severity, slower rates‐of‐recovery, and faster rates‐of‐relapse. Affect‐regulation theories posit that maladaptive exercise functions to reduce high negative affect (NA), although ...
