Analytical strategies for detecting drugs in biological samples rely on information on metabolism and elimination. 5F-PY-PICA belongs to the group of synthetic cannabinoids that are known to undergo excretion into the bile. The aims of this study were the in vitro identification of metabolites of 5F-PY-PICA and to determine which analytical targets are excreted into the bile and urine. Metabolites identified after incubation of 5F-PY-PICA with pooled human liver microsomes (pHLM), pooled human hepatocytes (pHH), or suspended and sandwich-cultured rat hepatocytes (SCRH)...

BACKGROUND: Launched in the US in 2012, Choosing Wisely(®) is a campaign promoted by the American Board of Internal Medicine (ABIM) Foundation with the goal of improving healthcare effectiveness by avoiding wasteful or unnecessary medical tests, treatments and procedures. It uses concise recommendations produced by national medical societies to start discussions between physicians and patients on the relevance of these services as part of a shared decision-making process. The Multiple Sclerosis Focus Group (Groupe de Reflexion Autour de la Sclérose en Plaques; GRESEP) undertook a pilot study to assess the relevance and feasibility of this approach in the management of multiple sclerosis (MS) in France...

Objective: It is recommended that positives in immunoassay drug screens be followed up with more specific confirmatory testing. The drug package insert for pantoprazole mentions reports of false-positive urine screening tests for tetrahydrocannabinol in patients receiving proton pump inhibitors, but no method details or data are given, referenced, or found in literature searches. Thus, we investigated this using our laboratory's assay. Methods: A spiked sample and samples from 32 patients taking a proton pump inhibitor were analyzed using the EMIT II Plus Cannabinoid assay with a 20 ng/mL cutoff...

Phenethylamine derivatives are being increasingly exploited for recreational use as "designer" stimulants designed to mimic psychostimulant properties of amphetamine or other illicit substances like 3,4-methylenedioxymethamphetamine (MDMA [ecstasy]). Clandestine operations meticulously design phenethylamines so the user can bypass legal action when detected, as many of these are yet to be regulated by government authorities. Substituted phenethylamines or 2C amines, N-methoxybenzyl derivatives of the corresponding 2C amines commonly known as NBOMe compounds, and cathinones are among the most commonly abused phenethylamines...

Human xylazine poisoning is uncommon. This report describes the use of xylazine for intentional poisoning with criminal intent. Two incidents occurred within 3 weeks: the first involved one victim, and the second involved two victims. The clinical presentations were brief coma, bradycardia, hypotension, and hyperglycemia. The victims recalled having been given a drink from a stranger in a hospital waiting room before loss of consciousness. In the first case, general drug screening by gas chromatography/mass spectrometry (MS) revealed xylazine in the gastric contents, but liquid chromatography-tandem MS (LC-MS/MS) of serum did not...

BACKGROUND: Among adolescents with type 1 diabetes, rapid increases in albumin excretion during puberty precede the development of microalbuminuria and macroalbuminuria, long-term risk factors for renal and cardiovascular disease. We hypothesized that adolescents with high levels of albumin excretion might benefit from angiotensin-converting-enzyme (ACE) inhibitors and statins, drugs that have not been fully evaluated in adolescents. METHODS: We screened 4407 adolescents with type 1 diabetes between the ages of 10 and 16 years of age and identified 1287 with values in the upper third of the albumin-to-creatinine ratios; 443 were randomly assigned in a placebo-controlled trial of an ACE inhibitor and a statin with the use of a 2-by-2 factorial design minimizing differences in baseline characteristics such as age, sex, and duration of diabetes...

Background: Drug overdose continues to be the most common cause of acute poisoning worldwide. There has been a substantial increase in drug overdose incidence and prevalence over the past decade, probably as a result of the emergence of new synthetic designer drugs. The purpose of this study is to describe the clinical and epidemiological characteristics of patients with acute drug intoxication admitted to the Intensive Care Unit (ICU). Methods: A single center, prospective, observational study was conducted among all adult patients with clinical signs suggestive of acute drug intoxication admitted from the Emergency Department (ED) to ICU during a 6-month period (September to March)...

PURPOSE/BACKGROUND: In animal models, levels of the neurosteroid pregnenolone increase after tetrahydrocannabinol (THC) administration and pregnenolone appears to attenuate the brain effects of THC. Given these interactions between pregnenolone and THC, we evaluated baseline neurosteroid levels in participants with a history of a cannabis use disorders (CUDs). METHODS/PROCEDURES: Bipolar depressed participants were enrolled in a randomized placebo-controlled clinical trial to evaluate the efficacy of add-on pregnenolone for depression and before receiving pregnenolone or placebo...

U-47700 was developed by the Upjohn Co. in the 1970s as part of their search for a selective μ-opioid agonist with similar potency as morphine. U-47700 has re-emerged recently in the illicit drug market and is easily and cheaply obtained via the internet as well as on the street, many times falsely sold as another drug. Several fatalities from U-47700 have been reported in scientific literature, often in combination with other intoxicants. This case report describes the first death in south-central Kansas resulting solely from U-47700 intoxication: a 26-year-old white male found dead in his bedroom with apparent drug paraphernalia...

Fentanyl analogs pose a unique challenge for forensic pathologists and toxicologists. The extreme potency of these analogs results in minute blood, urine and vitreous concentrations that are technically difficult to identify. This in addition to their absence from standard drug screening may potentiate a setting of apparent drug overdose without an immediately identifiable source. The following case series illustrates three such encounters with acrylfentanyl, an analog whose presence has not yet been reported in the scientific literature in the United States...

Objective: Although the Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) has become a widely used screener for aberrant opioid-related behavior in adults, the length of the instrument may limit its utility. The purpose of the current study was to develop a short form of the SOAPP-R by retaining as few items as possible while maximizing predictive accuracy. Methods: Participants (N = 555), recruited from pain clinics, completed the 24-item SOAPP-R and participated in a five-month follow-up visit to evaluate aberrant drug-related behaviors...
