BACKGROUND: Environmental and social trends and patients' characteristics may affect predictors for methadone maintenance treatment (MMT) outcome. METHODS: We have expanded our previous study of predictors for MMT outcome (from 619 to 890 patients) and the study period (from 15 to 24 years). Survival and retention in MMT since admission to the MMT clinic (6/1993-6/2016) and until death or study closure (6/2017) were compiled and analyzed. RESULTS: Of 890 patients ever admitted (10,146...

Drug withdrawal-associated aversive memories trigger relapse to drug-seeking behavior. Corticotrophin-releasing factor (CRF) is an important mediator of the reinforcing properties of drugs of abuse. However, the involvement of CRF1 receptor (CRF1R) in aversive memory induced by opiate withdrawal has yet to be elucidated. We used the conditioned-place aversion (CPA) paradigm to evaluate the role of CRF1R on opiate withdrawal memory acquisition, along with plasticity-related processes that occur after CPA within the basolateral amygdala (BLA) and dentate gyrus (DG)...

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...

Extracellular vesicles (EVs) are small vesicles secreted by cells and are known to carry sub-cellular components including microRNA, proteins, and lipids. Due to their ability to transport cargo between cells, EVs have been identified as important regulators of various pathophysiological conditions and can therefore influence treatment outcomes. In particular, the significance of microRNAs in EV-mediated cell-cell communication is well-documented. While the influence of EVs and the cargo delivered by EVs has been extensively reviewed in other neurological disorders, the available literature on the potential role of EVs in the pathophysiology of drug addiction has not been reviewed...

Toxicological investigations are often required by clinicians in comatose patients with suspected poisoning. However, the usefulness of toxicological analyses to support a diagnosis of acute poisoning is debated among clinicians and the interpretation of laboratory tests is challenging given the wide diversity of analytical techniques available. We report the case of an 8-year-old boy who was admitted to an intensive care unit with severe respiratory depression and neurological impairment. In order to formulate appropriate hypothesizes about the diagnosis and circumstances of intoxication, clinicians consulted toxicologists for a comprehensive toxicological screening...

Almost half of sickle cell disease (SCD) patients develop chronic, debilitating physical pain with uncertain genesis for which they primarily receive opiate-based palliative treatment. Psychological trauma exposure, especially interpersonal victimization, has been linked to the perception of pain in several medical diseases, but has yet to be examined in SCD patients. This study examines self-reported chronicity of pain and use of prescribed opiates in 50 adult SCD patients with and without a history of interpersonal violence exposure...

Inhalants, which are neurotoxic central nervous system (CNS) suppressants, are frequently abused by young adults. Unlike other CNS depressants, including alcohol and opiates, no treatment is currently approved for inhalant dependence. In this report, a novel approach of substitution treatment for inhalant addiction was explored in a double-blinded, randomized, controlled crossover design to examine the effects of inhalation of essential oil and perfume on the reduction of cue-induced craving for inhalant in thirty-four Thai males with inhalant dependence...

Background: Opioid substitution therapy (OST) is an evidence-based intervention for opiate-dependent persons that replaces illicit drug use with medically prescribed, orally administered opiates such as buprenorphine and methadone. OST reduces HIV risk behaviors and harms associated with injecting opioid. Most of the evidence for OST effectiveness has been generated in middle- and high-income countries where programs are mostly located in dedicated health-care settings; evidence regarding the outcomes of OST programs in low-income countries where OST is often provided in grassroots settings such as drop-in centers is limited...

Opiate abuse and addiction have become a worldwide epidemic with great societal and financial burdens, highlighting a critical need to understand the neurobiology of opiate addiction. While several studies have focused on drug-dependent changes in neurons, the role of glia in opiate addiction remains largely unstudied. RNA sequencing pathway analysis from the prefrontal cortex of male rats revealed changes in several genes associated with oligodendrocyte differentiation and maturation following heroin self-administration...

Accumulating evidence support the growing non-medical use of morphine during adolescence. Despite this concern which has recently been addressed in some studies, cellular mechanisms underlying the long-term neurobiological and behavioral effects of opiate exposure during this critical period have still remained largely unexplored. Several reports have proposed that subtle long-lasting neurobiological alterations might be triggered by exposure to opiate derivatives or drugs of abuse particularly when this occurs during a critical phase of brain maturation such as adolescence...

Pregabalin, a GABA analogue, binds to the alpha 2 delta subunit of voltage-dependent calcium channels. It is recognized as efficacious in pathologies such as epilepsy, neuropathic pain and anxiety disorders. Since pregabalin prescriptions have increased worldwide, reports of its abuse have been accumulating, mainly in patients with opioid abuse disorders. The present study investigated potential pregabalin abuse by means of hair analysis, a matrix that provides valuable retrospective information. Half of the pool of 280 susceptible patients had been occasional drug users and were being monitored for driving licence renewals...

The Substance Abuse and Mental Health Services Administration (2014) reported that 1.1% of pregnant women used nonprescription opiates (either heroin or prescription pills) in the last 30 days. Methadone and buprenorphine are the most common treatments for opiate addiction in pregnant women. Reasons for seeking opiate maintenance treatment (OMT) include keeping custody of one's children and the hope of developing a healthy parenting relationship. Yet, healthcare organizations and professionals have mixed opinions regarding health promotion within the maternal OMT population...
