The use of amphetamine-type stimulants (ATS) and ketamine is of particular clinical concern because of its associated psychotic symptoms. In Chinese clinical practice, ATS and ketamine are commonly used simultaneously, but very few studies have reported the symptom profile of users who use both drugs. This study determined whether the combined use of ATS and ketamine is associated with more psychotic symptoms than either ATS or ketamine alone. According to drug use characteristics, 375 Chinese synthetic drug users were categorized into 2 pairs of comparison groups: ATS-only (n=125) vs...

Genome-wide association studies in humans have suggested that variants of the cadherin-13 (CDH13) gene are associated with substance use disorder, subjective response to amphetamine, and attention deficit hyperactivity disorder. To examine the role of the Cdh13 and its peptide ligand adiponectin (AdipoQ) in addiction-related behaviors, we assessed Cdh13 knock-out rats and AdipoQ knock-out mice using intravenous cocaine self-administration and conditioned place preference paradigms. During intravenous cocaine self-administration, male Cdh13 heterozygous (+/-) and knock-out (-/-) rats showed increased cue-induced reinstatement compared to wild-type rats when presented with a cocaine-paired stimulus, whereas female Cdh13 rats showed no differences across genotype...

BACKGROUND AND AIMS: Research has shown that internet interventions can be effective for dependent users of various substances. However, less is known about the effects of these interventions on users of opioids, cocaine, and amphetamines than for other substances. We aimed to investigate the effectiveness of internet interventions in decreasing the usage of these types of substances. METHODS: We conducted a systematic literature search in the databases of PubMed, PsycINFO, Embase, and the Cochrane Library to identify randomized controlled trials examining the effectiveness of internet interventions compared with control conditions in reducing the use of opioids, cocaine, and amphetamines...

Drug abuse is considered as the most common poisoning in the world. Stimulants agent especially amphetamines and methamphetamines are among important abused substances. Different types of neurologic, psychiatric, respiratory, gastrointestinal, and cardiogenic complications have been reported to be related to methamphetamine consumption. Some of these substances could cause dysrhythmias which is the most prevalent etiology of cardiogenic syncope. Ecstasy, as one of the most commonly abused drugs, is known as a cause of cardiac dysrhythmias...

BACKGROUND: Many children and adolescents with attention deficit/hyperactivity disorder (ADHD) are treated with stimulant and non-stimulant medication. ADHD medication may be associated with cardiovascular effects. It is important to identify whether mean group effects translate into clinically relevant increases for some individual patients, and/or increase the risk for serious cardiovascular adverse events such as stroke or sudden death. OBJECTIVES: To evaluate potential cardiovascular effects of these treatments, we conducted a systematic review and meta-analysis of the effects of methylphenidate (MPH), amphetamines (AMP), and atomoxetine (ATX) on diastolic and systolic blood pressure (DBP, SBP) and heart rate (HR) in children and adolescents with ADHD...

INTRODUCTION: Illicit stimulants are often combined with alcohol in nightlife entertainment districts, an environment where aggressive behaviour commonly occurs. While alcohol and methamphetamine use are each associated with aggressive behaviour, relatively little is known about the impact of the combined use of alcohol and amphetamine-type stimulants (i.e., ecstasy [MDMA] and methamphetamine) on aggression. METHOD: Analysis of longitudinal data from a population-based sample of Australian young adult amphetamine-type stimulant users (n=248) to examine: (a) prevalence and timing of simultaneous alcohol and amphetamine-type stimulant use and (b) predictors of ecstasy- and methamphetamine-related aggression and hostility...

Nicole is a 15-year-old girl presenting to the Developmental Behavioral Pediatrics Clinic with symptoms of the inattentive type of Attention-Deficit/Hyperactivity Disorder (ADHD) and declining school performance over the last year. She expressed frustration over her inability to concentrate on schoolwork. Assuming that her poor grades were secondary to lack of effort, her parents withdrew privileges. Nicole became increasingly depressed. She stopped participating in activities, she previously enjoyed, and her parents reported that she stopped singing in the shower...

A method for the statistical comparison of mass spectral data is demonstrated for applications in controlled substance analysis. The method uses an unequal variance t-test at each mass-to-charge ratio in the scan range to determine if two spectra are statistically associated or discriminated. If the two spectra are associated, a random-match probability is calculated to estimate the likelihood that the mass spectral fragmentation pattern in question occurs by random chance alone. If the two spectra are discriminated, the fragment ions responsible for the discrimination are determined...

Lithium is the prototype mood stabilizer but its mechanism is still unresolved. Two hypotheses dominate-the consequences of lithium's inhibition of inositol monophosphatase at therapeutically relevant concentrations (the 'inositol depletion' hypothesis), and of glycogen-synthase kinase-3. To further elaborate the inositol depletion hypothesis that did not decisively determine whether inositol depletion per se, or phosphoinositols accumulation induces the beneficial effects, we utilized knockout mice of either of two inositol metabolism-related genes-IMPA1 or SMIT1, both mimic several lithium's behavioral and biochemical effects...

The striatum of the brain coordinates motor function. Dopamine-related drugs may be therapeutic to patients with striatal neurodegeneration, such as Huntington's disease (HD) and Parkinson's disease (PD), but these drugs have unwanted side effects. In addition to stimulating the release of norepinephrine, amphetamines, which are used for narcolepsy and attention-deficit/hyperactivity disorder (ADHD), trigger dopamine release in the striatum. The guanosine triphosphatase Ras homolog enriched in the striatum (Rhes) inhibits dopaminergic signaling in the striatum, is implicated in HD and L-dopa-induced dyskinesia, and has a role in striatal motor control...

Central hypersomnias principally involves type 1 narcolepsy (NT1), type 2 narcolepsy (NT2) and idiopathic hypersomnia (IH). Despite great progress made in understanding the physiopathology of NT1 with low cerebrospinal fluid hypocretin-1 levels, current treatment remains symptomatic. The same applies to NT2 and IH, for which the physiopathology is still largely unknown. Controlling excessive daytime sleepiness (EDS), cataplexy, hypnagogic hallucinations, sleep paralysis and disturbed night-time sleep are key therapeutic targets in NT1...

Cocaine- and amphetamine-regulated transcript (CART) is an anorexigenic peptide widely expressed in the central and peripheral nervous systems, as well as in endocrine cells. CART is markedly upregulated in the β-cells of several rodent models of type-2 diabetes. The stimulatory effect of exogenous CART peptide on insulin secretion is cAMP dependent. Glucose is the most important regulator of islet function. However, the role of CART in glucose-potentiated insulin secretion remains unclear. Here, our results showed that glucose time- and dose-dependently elicited CART mRNA expression in rat islets...

An advantage of differential mobility spectrometry (DMS) is it provides an orthogonal mechanism to mass spectrometry (MS). The DMS-MS/MS detects analytes in the gas phase on the basis of differences in ion mobility in low and high electric fields, which makes DMS-MS/MS an alternative to chromatographic separation-MS. One drawback of DMS is its limited resolution and sensitivity, especially for detecting small molecules when using a nonpolar inert gas as the carrier gas. The present work has evaluated the effects on peak capacity of adding chemical modifiers to inert carrier gases (nitrogen, helium, argon and carbon dioxide)...

Despite many benefits including simple point-of-care sample collection, reduced costs, and simplified shipping and storage, dried blood spot (DBS) techniques have faced adoption resistance due to factors such as the hematocrit (Hct) effects and the established preference for bioanalysis of plasma rather than whole blood. One way to potentially circumvent these challenges is to adopt the concept of dried plasma spot (DPS) techniques. One approach to accomplishing this is through an on-card red blood cell (RBC) filtration to generate plasma from whole blood without the need for centrifugation...

In monosymptomatic hypochondriacal psychosis (MHP), such as delusional infestation (DI), the patient has a fixed, false, encapsulated belief associated with tactile hallucinations (TH), most commonly formication, which is defined as cutaneous sensations of crawling, stinging, biting, etc., without evidence of infestation. Drug-induced TH should be considered in patients with suspected MHP. Although recreational drugs such as cocaine, amphetamines, and narcotics are well known to induce TH, many busy practicing dermatologists may not be familiar with other types of medications that can induce TH...
