Hands-Free Analytical Urine Testing Technology Validated for Drug-Facilitated Crime Investigations.

Forensic laboratories need quick and simple technology to improve turnaround times, while delivering reliable results. The goal of this study is first to create a simplified workflow to meet new Academy Standards Board requirements for urine testing in drug-facilitated crime investigations and, second, to create "ready-to-go", "hands-free" testing technology to further streamline analytical procedures. A first of its kind, the ToxBox forensic test kit is used to validate a single analytical procedure for opioids, benzodiazepines, cannabinoids, antidepressants, and several other drug classes.

Pharmacogenomic Profiling of Pediatric Patients on Psychotropic Medications in an Emergency Department.

Objective: The aim of the study was to evaluate the ability of a combinatorial pharmacogenomic test to predict medication blood levels and relative clinical improvements in a selected pediatric population.

Methods: This study enrolled patients between ages 3 to 18 years who presented to a pediatric emergency department with acute psychiatric, behavioral, or mental health crisis and/or concerns, and had previously been prescribed psychotropic medications. Patients received combinatorial pharmacogenomic testing with medications categorized according to gene-drug interactions (GDIs); medications with a GDI were considered "incongruent," and medications without a GDI were considered "congruent.

Synthetic cannabinoid poisonings and access to the legal cannabis market: findings from US national poison centre data 2016-2019.

Aim: To investigate trends in synthetic cannabinoid exposures reported to United States (US) poison control centres, and their association with status of state cannabis legalisation.

Methods: A retrospective study of National Poison Data System (NPDS) data from 2016 to 2019 identified and associated synthetic poisoning reports with annual state cannabis law and market status. State status was categorised as restrictive (cannabis illegal or limited medical legalisation), medical (allowing THC-containing medical cannabis use) and permissive (allowing non-medical use of THC-containing cannabis by adults).

Methylene Blue: An Antidote for Methemoglobinemia and Beyond.

Methylene blue has been in medicinal use for centuries and is best known as an antidotal treatment for acquired methemoglobinemia (MetHB). More recently, methylene blue has gained recognition for its efficacious use in the treatment of ifosfamide neurotoxicity and refractory vasoplegic shock in both the pediatric and adult critical care literature, extending its use beyond MetHB. Methylene blue's mechanism of action is somewhat complex and based partly on its oxidizing capabilities, ironically the same mechanism that causes MetHB.
