Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Do witnesses of functional/dissociative seizures recall them accurately? A UK experimental study of semiology recall at clinically relevant time points with a pilot intervention

open access: yesEpilepsia, EarlyView.
Abstract Objective Different causes of transient loss of consciousness (TLOC) carry distinct risks and require different management. Early accurate diagnosis is essential to guide counseling, investigation, and referral. In routine practice, frontline clinicians and specialists often rely on eyewitness accounts, yet the reliability of witness testimony
