Conflicting results emerged from studies investigating cognitive performances in migraine patients. Based on clinical and neuroradiological aspects, the possible involvement of executive functions has been especially taken into consideration. The aim of this study was to evaluate, in a population of subjects affected by migraine without aura (MwoA), frontal lobe cognitive functions. We enrolled all the consecutive patients affected by MwoA referred to our headache centre for a first evaluation. Each patient underwent a neuropsychological evaluation including Raven coloured progressive matrices (CPM)...

Migraine is a disabling neurovascular syndrome which affects 12-15% of the global population and it represents the third cause in years lived with disability in both males and females aged 15-49 years. Among migraineurs, the symptomatic drug abuse may be a risk factor in the development of medication overuse headache (MOH). Detecting cases of MOH is not straightforward; community pharmacists may, therefore, be in a strategic position to identify individuals who self-medicate, particularly with respect to prevent the development of MOH...

Autophagy has an essential role in neuronal homeostasis and its dysregulation has been recently linked to neurotoxic effects of a growing list of psychoactive drugs, including amphetamines. However, the role of autophagy in β-keto amphetamine (β-KA) designer drugs-induced neurotoxicity has hitherto not been investigated. In the present study, we show that two commonly abused cathinone derivatives, 3,4-methylenedioxymethcathinone (methylone) and 3,4-methylenedioxypyrovalerone (MDPV), elicit morphological changes consistent with autophagy and neurodegeneration, including formation of autophagic vacuoles and neurite retraction in dopaminergic SH-SY5Y cells...

Cannabis is a widely spread drug which chronic abuse may cause diverse adverse effects on the body, in the short and long term. Among these effects, we can cite digestive disorders, mainly characterized by the onset of cyclical vomiting illness. Vomiting symptoms can be temporarily relieved by hot water showers. As a matter of fact, many patients adopt a compulsive bathing behavior characterized by the irrepressible need of having showers or baths at a high temperature. We describe the case of two patients (22 and 23 years-old) who consume cannabis on a regular basis...

The current study examined differences in substance abuse treatment outcomes among racial and ethnic groups enrolled in the Stimulant Reduction Intervention using Dosed Exercise (STRIDE) trial, a multisite randomized clinical trial implemented through the National Institute on Drug Abuse's (NIDA's) Clinical Trials Network (CTN). STRIDE aimed to test vigorous exercise as a novel approach to the treatment of stimulant abuse compared to a health education intervention. A hurdle model with a complier average causal effects (CACE) adjustment was used to provide an unbiased estimate of the exercise effect had all participants been adherent to exercise...

Transgender women living with HIV experience high rates of substance use, violence, and post-traumatic stress disorder (PTSD). Seeking Safety is a manualized, present-focused, cognitive-behavioral therapy program designed to address co-occurring substance use and PTSD. Seeking Safety has evidence of efficacy in a variety of populations but had not been evaluated specifically with people living with HIV or transgender women. We pilot-tested a 12-session Seeking Safety program with a group of transgender women living with HIV who reported substance use and a history of violence...

Alcohol abuse causes major social, economic and health-related problems worldwide. Alcohol, like other drugs of abuse, increases levels of dopamine in the nucleus accumbens, facilitating behavioural reinforcement and substance abuse. Previous studies suggested that glycine receptors (GlyRs) are involved in the regulation of accumbal dopamine levels. Here, we investigated the presence of GlyRs in accumbal dopamine receptor medium spiny neurons (MSNs) of C57BL/6J mice, analyzing mRNA expression-levels and immunoreactivity of GlyR subunits, as well as ethanol sensitivity...

Rural-to-urban migrants are at high risk of HIV infection. The goal of this survey was to explore the commercial sexual behavior and condom use among male rural-to-urban migrants in western China. A cross-sectional survey on male rural-to-urban migrants in western China was conducted. Among all the subjects surveyed, 140 (7.4%) had commercial sexual behavior, which is associated with being aged older than 24 years, being of Han or other ethnic minorities, being divorced, separated, or widowed, having experienced drug abuse, having had heterosexual behavior, having had casual sexual partners, having had sex with a homosexual, and being from Xinjiang...

Opioid abuse in the United States has reached epidemic proportions, with treatment admissions and deaths associated with prescription opioid abuse quadrupling over the past 10 years. Although genetics are theorized to contribute substantially to inter-individual variability in the development, severity, and treatment outcomes of opioid abuse/addiction, little direct preclinical study has focused on the behavioral genetics of prescription opioid reinforcement and drug-taking. Herein, we employed different 129 substrains of mice currently available from The Jackson Laboratory (129S1/SvlmJ, 129X1/SvJ, 129S4/SvJaeJ and 129P3/J) as a model system of genetic variation and assayed mice for oral opioid intake and reinforcement, as well as behavioral and somatic signs of dependence...

Acute and prolonged exposure to drugs of abuse induces changes in gene expression, synaptic function, and neural plasticity in brain regions involved in reward. Numerous genes are involved in this process, and persistent changes in gene expression coincide with epigenetic histone modifications and DNA methylation. Histone modifications are attractive regulatory mechanisms, which can encode complex environmental signals in the genome of postmitotic cells, like neurons. Recently, it has been demonstrated that specific histone modifications are involved in addiction-related gene regulatory mechanisms, by a diverse set of histone-modifying enzymes and readers...

Hair testing is a powerful tool routinely used for the detection of drugs of abuse. The analysis of hair is highly advantageous as it can provide prolonged drug detectability versus that in biological fluids and chronological information about drug intake based on the average growth of hair. However, current methodology requires large amounts of hair samples and involves complex time-consuming sample preparation followed by gas or liquid chromatography coupled with mass spectrometry. Mass spectrometry imaging is increasingly being used for the analysis of single hair samples, as it provides more accurate and visual chronological information in single hair samples...

Understanding the neural mechanisms of risky decision-making is critical to developing appropriate treatments for psychiatric disorders, problem gambling, and addiction to drugs of abuse. Probing neurobiological mechanisms requires the use of nonhuman animal models (particularly rhesus macaques, rats, and mice). However, there is considerable variation across species in risk preferences. Nevertheless, there are shared core features of risky decision-making present across species. As demonstrated with a wide variety of behavioral paradigms, modulators of risk preference observed in humans are readily replicated in model species...

Synthetic cannabinoids are becoming increasingly popular as substances of abuse. However, in the Netherlands synthetic cannabinoid intoxications are rare. We report a 16-year-old male who became deeply comatose and was admitted to the intensive care unit for invasive mechanical ventilation after a buse of aninitially unknown drug. Routine toxicology screening with an immunoassay only detected tetrahydrocannabinol, but additional tests with liquid chromatography mass spectrometry revealed synthetic cannabinoid use...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. It is closely related to the epidemic of obesity, metabolic syndrome or type 2 diabetes mellitus (T2DM). NAFLD can cause liver inflammation and progress to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis or hepatocellular cancer (HCC). Nevertheless, cardiovascular disease (CVD) is the most common cause of death in NAFLD/NASH patients...

Substance use among pregnant women is a major public health issue. Both prescription opioid use and illicit opioid abuse have increased dramatically in recent years. Prolonged in utero drug exposure may result in neonatal abstinence syndrome (NAS), an acute multisystemic clinical entity that occurs in the first days of life. This syndrome is caused by abrupt discontinuation of fetal exposure to licit or illicit drugs chronically consumed by the mother during pregnancy and transmitted to the fetus through the placenta...

BACKGROUND: High-risk drug consumption is a considerable problem for public health actors in industrialised countries. The latest trends show a market tendency towards diversification and increasing demand for high-purity synthetic drugs. Whilst most consumers seek medical help after cannabis use, it is high-risk drugs like cocaine, heroin and amphetamines that account for most of the 1000 drug-related deaths that occur in Germany every year. PURPOSE: This article presents the most prominent in vivo cerebral metabolic information in cocaine, heroin and methamphetamine users provided by MRI spectroscopy and PET imaging...

Prenatal cocaine exposure (PCE) may increase adolescent substance use through alterations of neurotransmitter systems affecting fetal brain development. The relationship between PCE and substance use at 15 and 17 years was examined. Subjects (365: 186 PCE; 179 non-cocaine exposed (NCE)) supplied biologic and self-report data using the Youth Risk Behavior Surveillance System (YRBSS) and Computerized Diagnostic Interview Schedule for Children (C-DISC 4) at ages 15 and 17. The relationship between PCE and substance use was assessed using General Estimating Equation (GEE) analyses controlling for confounding factors including violence exposure and preschool lead level...
