Investigations Into the Metabolism and Elimination of Tesofensine in Human Urine

Drug Testing and Analysis, EarlyView.
This study investigated tesofensine metabolism and urinary elimination after a single 483 μg intake via a dietary supplement. In six volunteers, urine was collected up to 659 h. LC‐HRMS/MS identified four tentative metabolites; maximum urinary concentrations reached 4 ng/mL within 4–48 h.

A translational multimodal machine‐learning prototype predicting valproate response in epilepsy treatment

Epilepsia, EarlyView.
Abstract Objective Epilepsy affects ~1% of the global population and often requires lifelong antiseizure medication (ASM) therapy. Valproic acid (VPA) is a commonly prescribed first‐line ASM, yet only approximately half of patients achieve sustained seizure freedom. Treatment selection remains largely empirical.
