Although most people who inject drugs (PWID) report receiving assistance during injection initiation events, little research has focused on risk factors among PWID for providing injection initiation assistance. We therefore sought to determine the influence of non-injection drug use among PWID on their risk to initiate others. We used generalized estimating equation (GEE) models on longitudinal data among a prospective cohort of PWID in Tijuana, Mexico (Proyecto El Cuete IV), while controlling for potential confounders...

Even following long periods of abstinence, individuals with anxiety disorders have high rates of relapse to drugs of abuse. Although many current models of relapse demonstrate effects of acute stress on drug-seeking, most of these studies examine stressful experiences that occur in close temporal and physical proximity to the reinstatement test. Here, we assess the effects of a stressful experience in one context on fear and drug-seeking in a different context. We adapt the stress-enhanced fear learning procedure to examine impacts on drug-seeking long after the stressful experience occurred...

OBJECTIVE: The spread of new psychoactive substances (NPS) has expanded rapidly in the last decade. The complexity of the pharmacological effects of NPS challenges the traditional treatment guidelines, and information of the emergence of new arrivals is valuable. Our knowledge on the actual range of recreational drugs used and NPS available in Denmark is limited as identification is possible only when consumers become patients in the healthcare system or through drug seizures. We aimed to detect classical recreational drugs and NPS in the urine of music festival attendees and evaluate if the use of NPS could have been predicted by comparing study data with drug seizure data from the previous year published by European and Danish health authorities...

BACKGROUND: Data on both known and unknown drug use in the electronic dance music (EDM) scene is important to inform prevention and harm reduction. While surveys are the most common method of querying drug use, additional biological data can help validate use and detect unknown/unintentional use of drugs such as new psychoactive substances (NPS). We sought to determine the extent of both known and unknown use of various substances in this high-risk scene. METHODS: We hair-tested 90 self-reported past-year ecstasy/MDMA/Molly users attending EDM parties in New York City during the summer of 2016 using UHPLC-MS/MS...

Our previous studies have raised the possibility that altered blood glucose levels may influence and/or be predictive of methamphetamine (METH) neurotoxicity. This study evaluated the effects of exogenous glucose and corticosterone (CORT) pretreatment alone or in combination with METH on blood glucose levels and the neural and vascular toxicity produced. METH exposure consisted of four sequential injections of 5, 7.5, 10, and 10 mg/kg (2h between injections) D-METH. The three groups given METH in combination with saline, glucose (METH+Glucose), or CORT (METH+CORT) had significantly higher glucose levels compared to the corresponding treatment groups without METH except at 3 h after the last injection...

Conventional Surface-Enhanced Raman Spectroscopy (SERS) for fast detection of drugs in urine on the portable Raman spectrometer remains challenges because of low sensitivity and unreliable Raman signal, and spectra process with manual intervention. Here, we develop a novel detection method of drugs in urine using chemometric methods and dynamic SERS (D-SERS) with mPEG-SH coated gold nanorods (GNRs). D-SERS combined with the uniform GNRs can obtain giant enhancement, and the signal is also of high reproducibility...

Methamphetamine (METH) is a highly addictive drug of abuse which induces behavioral sensitization and rewarding effects. Thioredoxin-1 (Trx-1) is a redox protein and plays role in regulating activity of transcription factor, such as cAMP responsive element-binding protein (CREB), AP-1, p53, is emerging as an important modulator of neuronal function. It has been reported that Trx-1 is involved in morphine dependence. In this study, we examined the rewarding effect after METH administration by conditioned place preference (CPP) of mice, and detected the levels of dopamine and the activity of cAMP responsive element-binding protein (CREB), the expressions of ΔFosB and cyclin-dependent kinase 5 (CDK5) in the ventral tegmental area (VTA) and nucleus accumbens (NAc) in mice...

Deaths involved with environmental hazards and intoxication might present with minimal or nonspecific morphological features, which are insufficient to establish a diagnosis. The present study investigated the postmortem brain mRNA and immunohistochemical expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), inducible nitric oxide synthase (iNOS) and nuclear factor erythroid-2-related factor-2 (Nrf2) in forensic cases. Relative mRNA quantification using Taqman real-time PCR assay demonstrated higher expression of IL-1β, TNF-α and iNOS, and lower expression of Nrf2 in methamphetamine intoxication and hyperthermia cases, higher expression of iNOS in phenobarbital intoxication cases, and higher expression of Nrf2 in phenobarbital intoxication and hypothermia cases...

In prior research, having traits consistent with a personality disorder has been shown to be related to substance use and high-risk sexual activity; however, few studies have examined relationships between dependency traits and health-jeopardizing behaviors. Individuals with traits consistent with dependent personality disorder may be more likely to be in a primary relationship characterized by unhealthy conditions, including physical abuse from a partner, low assertiveness in sexual situations, and partner infidelity...

A 19-year-old woman with insulin-dependent diabetes mellitus was found dead in bed having allegedly recently taken ecstasy and consumed alcohol. At autopsy, there were microhemorrhages in the brain with subnuclear vacuolization and Armanni-Ebstein changes in renal tubules. Biochemical analyses confirmed diabetic ketoacidosis (vitreous glucose-46.5 mmol/L; β-OH butyrate-13.86 mmol/L.). Toxicological analyses of blood showed a low level of 3,4-methylenedioxy-methamphetamine (MDMA) (0.01 mg/L), with acetone but no alcohol or other common drugs...

Men who have sex with men (MSM) who attend group sex events (GSEs) tend to also engage in high-risk sexual behaviors and substance use that may place them at additional increased risk for becoming infected with HIV. These sorts of events may be facilitated by the use of geosocial-networking smartphone applications, where MSM may have access to a large virtual pool of potential partners. The purpose of the current study was to examine the prevalence of recent engagement in GSEs and its demographic and behavioral correlates among a sample of MSM ( n = 202)...

Drug abuse (e.g., methamphetamine-Meth or cocaine-Coc) is one of the major risk factors for becoming infected with HIV-1, and studies show that in combination, drug abuse and HIV-1 lead to significantly greater damage to CNS. To overcome these issues, we have developed a novel nanoformulation (NF) for drug-abusing population infected with HIV-1. In this work, a novel approach was developed for the co-encapsulation of Nelfinavir (Nel) and Rimcazole (Rico) using layer-by-layer (LbL) assembled magnetic nanoformulation for the cure of neuroAIDS...
