INTRODUCTION: Prescription-drug use in the USA has increased by more than 60% in the last three decades. Prevalence of prescription-drug use among pregnant women is currently estimated around 50%. Prevalence of illicit drug use in the USA is 14.6% among pregnant adolescents, 8.6% among pregnant young adults and 3.2% among pregnant adults. The first step in identifying problematic drug use during pregnancy is screening; however, no specific substance-use screener has been universally recommended for use with pregnant women to identify illicit or prescription-drug use...

Introduction: Opioid use disorder (OUD) is characterized by a problematic pattern of opioid use leading to clinically-significant impairment or distress. Opioid agonist treatment is an integral component of OUD management, and buprenorphine is often utilized in OUD management due to strong clinical evidence for efficacy. However, interindividual genetic differences in buprenorphine metabolism may result in variable treatment response, leaving some patients undertreated and at increased risk for relapse...

Analytical chemistry represents a central aspect of doping controls. Routine sports drug testing approaches are primarily designed to address the question whether a prohibited substance is present in a doping control sample and whether prohibited methods (for example, blood transfusion or sample manipulation) have been conducted by an athlete. As some athletes have availed themselves of the substantial breadth of research and development in the pharmaceutical arena, proactive and preventive measures are required such as the early implementation of new drug candidates and corresponding metabolites into routine doping control assays, even though these drug candidates are to date not approved for human use...

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the region of the ATXN3 gene. The main feature of SCA3 is progressive ataxia, which affects balance, gait, and speech. Urine cells (UCs) of a SCA3 patient were successfully translated to induced pluripotent stem cells (iPSCs) by using the Sendai virus delivery system. ZZUi004-A cell line may provide a robust platform for further study of SCA3 pathogenesis as well as drug testing and gene therapy research...

Small intestinal endocrine tumours (SI-NETs) are generally considered resistant to systemic treatment. To date, predictive markers for drug activity are lacking. Tumour samples from 27 patients with SI-NETs were analyzed ex vivo for sensitivity to a panel of cytotoxic drugs and targeted agents using a short-term total cell kill assay. Samples of renal cancer, colorectal cancer (CRC), ovarian cancer, and chronic lymphocytic leukemia (CLL) were included for comparison. For the SI-NET subset, drug sensitivity was analyzed in relation to clinico-pathological variables and pre-treatment biomarkers...

BACKGROUND: Synthetic opioid overdose mortality among young adults has risen more than 300% in the USA since 2013, primarily due to the contamination of heroin and other drugs with illicitly manufactured fentanyl. Rapid test strips, which can be used to detect the presence of fentanyl in drug samples (before use) or urine (after use), may help inform people about their exposure risk. The purpose of this study was to determine whether young adults who use drugs were willing to use rapid test strips as a harm reduction intervention to prevent overdose...

Maternal substance abuse during pregnancy is a growing problem with major public health and legal concerns. In utero substance exposure may adversely affect neonatal development, pregnancy outcome and the long term behavioral, cognitive and developmental abilities of the child. Also, serious legal implications are associated with substance abuse during pregnancy, including charges of child abuse and neglect which may result in removal of the neonate from parental care and loss of custodial rights. Timely detection of in utero drug exposure is necessary for early identification and effective management of exposed newborns...

BACKGROUND: Problems with self-reported drug use include difficulties with recall and recognition as well as the desire to respond to questions in a socially desirable manner. Various methods have been developed to improve and/or validate estimates based on direct questioning of individuals regarding their substance use. For this study, we were interested in validating self-reported use of: 1) tobacco, 2) marijuana, and 3) other substances (i.e., heroin, cocaine, opiates, oxycodone, benzodiazepines, methamphetamine, phencyclidine, and barbiturates) employing urinalysis among inmates who participated in a randomized controlled trial of a smoking abstinence intervention in a tobacco-free prison located in the northeastern United States...

Characterized by periodic crescendo-decrescendo pattern of breathing alternating with central apneas, Central sleep apnea (CSA) with Cheyne-Stokes Breathing represents a highly prevalent, yet underdiagnosed comorbidity in chronic heart failure (CHF). A diverse body of evidence demonstrates increased morbidity and mortality in the presence of CSB. CSB has been described in both CHF patients with preserved and reduced ejection fraction, regardless of drug treatment. Risk factors for CSB are older age, male gender, high BMI, atrial fibrillation and hypocapnia...

A method was developed for the screening and quantification of seven amphetamine-type stimulants (ATS) and 22 cathinones, including three metabolites, in urine with Gas Chromatography-Mass Spectrometry. This method allowed the detection and quantification of ATS and cathinones group molecules using one procedure. A study of the stability of the drug mixtures for a period of 201 days in human urine samples under three different conditions has been carried. The ATS and cathinones include amphetamine, methamphetamine, MDA, MDEA, MDMA, PMA, PMMA, cathinone, methcathinone, 3'-position-substituted, ring-substituted, methylenedioxy-substituted, N-alkyl-substituted and pyrrolidinyl-substituted...

The occurrence of ractopamine (RAC) hydrochloride in water bodies is of significant concern due to its ecological impacts and toxicity to humans. RAC hydrochloride is a β-adrenergic agonist drug used as a feed additive to (1) improve feed efficiency, (2) rate of weight gain, and (3) increase carcass leanness in animals raised for their meat. This drug is excreted by animals in urine and introduced into the environment affecting nontarget organisms including fish. In wastewater released from farms, RAC concentrations were detected from 0...

In recent decades, urine drug testing in the workplace has become common in many countries in the world. There have been several studies concerning the use of the urine specimen validity test (SVT) for drug abuse testing administered in the workplace. However, very little data exists concerning the urine SVT on drug abuse tests from court specimens, including dilute, substituted, adulterated, and invalid tests. We investigated 21,696 submitted urine drug test samples for SVT from workplace and court settings in southern Taiwan over 5 years...

OBJECTIVE: Marijuana is the most commonly used illicit drug in the United States and co-use with tobacco is increasing. Preliminary studies have indicated that marijuana may suppress luteinizing hormone (LH) or shorten the luteal phase. Although the literature is mixed, these sex hormones may play a role in smoking cessation outcomes. This secondary subgroup analysis aims to explore the menstrual cycle of females who co-use marijuana and tobacco compared with females who only use tobacco in a sample of tobacco treatment-seeking individuals...

The Opioid Abuse Risk Screener was developed to support well-informed decision-making in opioid analgesic prescribing by extending the breadth of psychiatric risk factors evaluated relative to other non-clinician-administered measures. We examined the preliminary predictive validity of the Opioid Abuse Risk Screener relative to the widely used Screener and Opioid Assessment for Patients with Pain-Revised in predicting aberrant urine drug tests and controlled substance database checks. The Opioid Abuse Risk Screener is significantly different from the Screener and Opioid Assessment for Patients with Pain-Revised in predicting aberrant same-day urine drug tests (Z = 2...
