Background: The catecholamines such as dopamine, norepinephrine, and epinephrine are neurotransmitters that regulate different physiological functions of the central nervous system. Some evidence suggest that the degeneration of dopamine neurons in the substantia nigra contributes in Parkinson's disease (PD), which is a neurodegenerative disorder and it is responsible for the major symptoms of PD. It is suggested that replenishment of striatal dopamine through the oral administration of the dopamine precursor, levodopa, can compensate the lack of endogenously produced dopamine. Read More

Objectives: To estimate trends in incidence, outcomes, and costs among hospital deliveries related to amphetamines and opioids.
Methods: We analyzed 2004-to-2015 data from the National Inpatient Sample, a nationally representative sample of hospital discharges in the United States compiled by the Healthcare Cost and Utilization Project, by using a repeated cross-sectional design. We estimated the incidence of hospital deliveries related to maternal amphetamine or opioid use with weighted logistic regression. Read More

Background And Aims: There is limited evidence on what shapes amphetamine-type stimulant (ATS) use trajectories. This systematic narrative review and qualitative synthesis aimed to identify individual, social and environmental influences shaping key phases in the ATS use trajectory: initiation, continuation, increase/relapse and decrease/abstinence.
Methods: MEDLINE, PsycINFO, EMBASE, and PROQUEST (social science premium collection) were searched from 2000 to 2018. Read More

The abuse of amphetamine-type stimulants (ATS) has become a global public health issue in recent years, these new-type drugs can cause addiction and serious cognitive impairment. However, there are no effective methods for the prevention and treatment of ATS addiction at present. Repetitive transcranial magnetic stimulation (rTMS) is a painless and non-invasive new therapeutic approach that has been used for the treatment of depression and other neuropsychiatric disorders, but whether it can be used to treat drug addiction is unclear.

Despite the efforts to prevent the spread of new psychoactive substances (NPS) such as synthetic amphetamine derivatives, it is apparent that newer types of NPS are still emerging on the market in recent years. Due to high potential for their abuse, reliable analytical methods are required to determine these substances in biological samples. The objective of this study was to develop and validate the gas chromatography-mass spectrometric (GC-MS) method for the simultaneous determination of 13 amphetamine-related NPS (amphetamine; AP, 4-fluoroamphetamine; 4FA, methamphamine; MA, 4-fluoromethamphetamine; 4FMA, 4-chloroamphetamine; 4CA, para-methoxyamphetamine; PMA, 4-chloromethamphetamine; 4CMA, 6-(2-aminopropyl)benzofuran; 6APB, 4-methylenedioxyamphetamine; MDA, para-methoxymethamphetamine; PMMA, 6-(2-methylaminopropyl)benzofuran; 6MAPB, 3,4-methylenedioxymethamphetamine; MDMA, 5,6-methylenedioxy-2-aminoindane; MDAI) in urine.

Background: Previous studies have suggested that varenicline, an α4β2 nicotinic receptor partial agonist, and α7 nicotinic receptor full agonist, may be effective for the treatment of methamphetamine (MA) dependence due to dopaminergic effects, relief of glutamatergic and cognitive dysfunction, and activation of nicotinic cholinergic systems. This study aimed to determine if varenicline (1 mg BID) resulted in reduced methamphetamine use compared to placebo among treatment-seeking MA-dependent volunteers.
Methods: Treatment-seeking MA-dependent volunteers were randomized to varenicline 1 mg twice daily (n = 27) or placebo (n = 25) and cognitive behavioral therapy for 9 weeks. Read More

Objective: False-positive urine drug of abuse screening (UDS) results can have serious implications in clinical practice, particularly when confirmation assay results are not immediately available to providers making medical decisions. Often it is not possible to identify the specific medication or other interfering compound that is responsible for the false-positive UDS result. Even when a potential interference is reported in the literature or package insert for one assay, the applicability to other UDS platforms/assays is often unknown. Read More

Adolescents and females experience worse outcomes of drug use compared to adults and males. This could result from age- and sex-specific consequences of drug exposure on brain function and cognitive behavior.

This is a case of a 31-year-old Filipino man with chronic methamphetamine use disorder who developed tetanus from a necrotic skin graft over his left calcaneus, which was fractured after a motor vehicular accident. During the course of his illness, the patient's muscle spasms were unusually refractory to benzodiazepine, which is the first-line drug used in the management of muscle spasms. The muscle spasms were successfully controlled on the seventh day of illness with rocuronium at a dose of 10 μg/kg/min and midazolam at 0. Read More

Previous studies have consistently demonstrated that the amphetamine-related drug 3,4-methylenedioxymethamphetamine (MDMA) induces dopaminergic damage in the mouse brain, and that this effect is most marked in the nigrostriatal system. Moreover, it has been suggested that the overproduction of nitric oxide (NO) may participate in the dopaminergic damage induced by MDMA. To further elucidate this issue, we evaluated the levels of the enzyme nitric oxide synthase (nNOS), which catalyzes the production of NO, in mice treated with regimens of MDMA that induce progressive and persistent neurotoxicity in the dopaminergic nigrostriatal system.

Background: Abuse of psychostimulants, including methamphetamine (MA), has been linked to heightened impulsivity. While previous research has demonstrated differences in impulsivity between MA users and non-substance users, less is known about variability in impulsivity within MA users and whether the severity of MA use related problems predicts impulsivity within individuals who regularly use MA. This study aims to elucidate the relationship between impulsivity and MA use severity. Read More

Currently, there is not an effective treatment for 3,4-methylenedioxymethamphetamine (MDMA) dependence but pharmacotherapies targeting glutamate neurotransmission are a promising strategy. Previously, we showed that blockade of glutamate NMDA and AMPA receptors impairs the conditioned rewarding effects of MDMA and cocaine, respectively. In this study we evaluated the role of AMPA receptors in the rewarding effects of MDMA in mice using the conditioned place preference (CPP) paradigm. Read More

Background: Treatment as Prevention (TasP) leading to increased HIV treatment optimism among men who have sex with men (MSM) has been previously associated with behavioural risk compensation, though not yet via crystal methamphetamine (CM) use. Among HIV-negative MSM in a TasP environment, this study aimed to investigate the prevalence of recent CM use over time, examine the association between HIV treatment optimism and CM use and initiation, and identify correlates of recent CM use and predictors of CM initiation.
Methods: Using data from a prospective behavioural cohort study of sexually active MSM in the Vancouver area, we used multi-level generalized mixed effect models to evaluate temporal trends in CM use, univariable and multivariable logistic regression to identify covariates of recent CM use, and univariable and multivariable survival analysis to identify predictors of CM initiation.

While individual differences in reward sensitivity are believed to generalize across drugs and alternative rewards, this notion has received little empirical attention in human research.

Healthy volunteers ( n=95; age 18-35 years) completed questionnaires measuring the self-reported pleasurable effects of physical activity and other covariates, and this was followed by two double-blind counterbalanced sessions during which they received either 20 mg oral d-amphetamine or placebo.
