Evaluation of Therapeutic Opioids in Skin‐Derived Matrices (Sweat and Sebum) of Neonatal and Pediatric Patients and Their Role in Opioid Incorporation Into Hair

open access: yesDrug Testing and Analysis, EarlyView.
Concentration ranges, dose–concentration relationships, and metabolite‐to‐parent drug ratios of therapeutic opioids were evaluated in hair and skin swab samples of 150 pediatric patients. Skin‐derived matrices such as sweat or sebum were shown to contribute to analyte incorporation into hair in a systematic manner.

Evaluating Transcriptomic Biomarkers for rHuEPO Detection: Assessing the Impact of Exercise and Altitude Exposure

open access: yesDrug Testing and Analysis, EarlyView.
A two‐stage transcriptomic filter comparing rHuEPO, exercise and altitude responses reduced 153 candidate genes to 50 that were unaffected by physiological stimuli. These retained transcripts offer focused biomarker leads to strengthen antidoping detection of rHuEPO.

Bromazolam Tablet Quantification and Analysis of Post‐Mortem Cases From the National Programme on Substance Use Mortality (NPSUM)

open access: yesDrug Testing and Analysis, EarlyView.
Tablets submitted to drug checking services that were found to contain bromazolam. Over half of these counterfeit tablets mimicked the appearance of licensed formulations (e.g., alprazolam Xanax bars and diazepam Roche 10 mg pills). Bromazolam is now the most commonly detected street benzodiazepine in drug poisoning deaths in the United Kingdom ...

Isomer Composition Assessment of Synthetic Phosphatidylethanol by Collision‐Induced and Ozone‐Induced Dissociation Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
This study examines the isomeric composition of PEth reference materials and compares it with the natural variation in isomer distribution found in blood samples. ABSTRACT The direct blood‐alcohol biomarker phosphatidylethanol (PEth), especially its most abundant analogue 1‐palmitoyl‐2‐oleoyl‐sn‐phosphatidylethanol (PEth 16:0/18:1) has gained ...

Detection of a Distinct Erythropoietin (EPO) Profile After Isoelectric Focusing in Patients With Familial Erythrocytosis

open access: yesDrug Testing and Analysis, EarlyView.
A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It

Concentration and Detection Time of Nitrous Oxide in Blood Following Controlled Inhalation

open access: yesDrug Testing and Analysis, EarlyView.
In a study with controlled inhalation of nitrous oxide (N2O), elimination followed a two‐compartment model with half‐lives of 2.4 and 31 min, and N2O remained detectable in blood samples for 1–3 h after inhalation. ABSTRACT Recreational use of nitrous oxide (laughing gas, N2O) is becoming increasingly common and abuse is often seen in relation to ...
