Receptive anal intercourse, multiple partners, condomless sex, sexually transmitted infections (STIs), and drug/alcohol addiction are familiar factors that correlate with increased human immunodeficiency virus (HIV) risk among men who have sex with men (MSM). To improve estimation to HIV acquisition, we created a composite score using questions from routine survey of 3588 MSM in Beijing, China. The HIV prevalence was 13.4%. A risk scoring tool using penalized maximum likelihood multivariable logistic regression modeling was developed, deploying backward step-down variable selection to obtain a reduced-form model...

Energy drinks have been linked to a number of deleterious health outcomes among youth. Even so, the underlying risk factors for energy drink consumption among youth are less frequently examined. The present study examines the link between adolescent victimization experiences (i.e., property and violent victimization) and energy drink consumption among a nationally representative sample of adolescents. We employed the seven most recent cohorts (2010-2016) from the Monitoring the Future (MTF) study. A multi-stage random sampling technique was used to acquire the U...

The endocannabinoid (eCB) system is involved in the modulation of the reward system and participates in the reinforcing effects of different drugs of abuse, including alcohol. The most abundant receptor of the eCB system in the central nervous system is the CB1 receptor (CB1R), which is predominantly expressed in areas involved in drug addiction, such as the nucleus accumbens, the ventral tegmental area, the substantia nigra and the raphe nucleus. CB1R is expressed in early stages during development, and reaches maximum levels during early adolescence...

BACKGROUND: Elevated frontal and striatal reactivity to drug cues is a transdiagnostic hallmark of substance use disorders. The goal of these experiments was to determine if it is possible to decrease frontal and striatal reactivity to drug cues in both cocaine users and heavy alcohol users through continuous theta burst stimulation (cTBS) to the left ventromedial prefrontal cortex (VMPFC). METHODS: Two single-blinded, within-subject, active sham-controlled experiments were performed wherein neural reactivity to drug/alcohol cues versus neutral cues was evaluated immediately before and after receiving real or sham cTBS (110% resting motor threshold, 3600 pulses, Fp1 location; N = 49: 25 cocaine users [experiment 1], 24 alcohol users [experiment 2]; 196 total functional magnetic resonance imaging scans)...

OBJECTIVES: Offspring with family history of alcoholism are considered to be at high risk for alcoholism. The present study sought to expand our understanding of cognitive and behavioural dispositions associated with executive control and self-regulation in alcohol naïve offspring with and without family history of alcoholism. METHODS: Sample comprised of alcohol naive offspring in two groups: (i) at high risk (n = 34) and (ii) at low risk for alcoholism (n = 34)...

Currently available pharmacotherapies for treating alcohol use disorder (AUD) suffer from deleterious side effects and are not efficacious in diverse populations. Clinical and preclinical studies provide evidence that the Kcnq family of genes that encode KV 7 channels influence alcohol intake and dependence. KV 7 channels are a class of slowly activating voltage-dependent K+ channels that regulate neuronal excitability. Studies indicate that the KV 7 channel positive modulator retigabine can decrease dopaminergic neuron firing, alter dopamine (DA) release, and reduce alcohol intake in heavy drinking rodents...

Increasing evidence focuses on the endocannabinoid system as a relevant player in the induction of aberrant synaptic plasticity and related addictive phenotype following chronic excessive alcohol drinking. Besides, the endocannabinoid system is implicated in the pathogenesis of alcoholic liver disease. Interestingly, whereas the involvement of CB1 cannabinoid receptors in alcohol rewarding properties is established, the central and peripheral action of CB2 cannabinoid signalling is still to be elucidated. This review aims at giving the input to deepen knowledge on the role of the endocannabinoid system, highlighting the advancing evidence that suggests that CB1 and CB2 receptors may play opposite roles in the regulation of both the reinforcing properties of alcohol in the brain and the mechanisms responsible for cell injury and inflammation in the hepatic tissue...

A 48-year-old man, former alcohol abuser and drug addicted, was referred to our tertiary referral centre for iron disorders because of marked hyperferritinaemia. His clinical history revealed chronic hepatitis C, ß-thalassaemia trait and post-traumatic splenectomy at age of 22. MRI-estimated liver iron content was markedly elevated, while first-line genetic test for haemochromatosis was negative. Alpha-fetoprotein was increased but liver ultrasonography did not reveal focal liver lesions. Multiphasic contrast-enhanced CT confirmed this result but showed two abdominal masses (diameter of 9 cm and 7 cm, respectively) among bowel loops, strongly suspicious for cancer...

The study analyzed health professionals' conceptions toward female users of crack and powder cocaine currently receiving psychosocial care, based on a gender perspective. Seventeen health professionals were interviewed, and systematic observations were made of the spaces for collective care in a Center for Psychosocial Care specializing in alcohol and drug addiction in Greater Metropolitan Rio de Janeiro, Brazil. Analysis of the interviews and field diaries using the hermeneutic-dialectic method revealed three categories: frailty as a constitutive attribute of women's condition, the women's emotional addiction to crack and powder cocaine use, and gender stereotypes during psychosocial care...

BACKGROUND: Studies in humans and animals suggest a shift from goal-directed to habitual decision-making in addiction. We therefore tested whether acute alcohol administration reduces goal-directed and promotes habitual decision-making, and whether these effects are moderated by self-reported drinking problems. METHODS: Fifty-three socially drinking males completed the two-step task in a randomised crossover design while receiving an intravenous infusion of ethanol (blood alcohol level=80 mg%), or placebo...

Background: The safety and efficacy of long-term opioid treatment for chronic noncancer pain (CNCP) remains controversial. This study examined whether patients who report problematic opioid use sought help and/or perceived barriers to help-seeking. Methods: Data were collected from 1,086 people prescribed opioids for CNCP via a large prospective cohort called the Pain and Opioids IN Treatment (POINT) study. Patients' characteristics and help-seeking were examined according to scores on the Prescribed Opioids Difficulties Scale (PODS)...

Animal and cross-sectional human studies suggest that chronic cocaine use is associated with altered responsivity of the hypothalamic-pituitary-adrenal axis to stress. Moreover, increased susceptibility to stress has been proposed as an important factor for development, maintenance and relapse of cocaine addiction. As the glucocorticoid receptor gene (NR3C1) mediates genomic effects of the stress hormone cortisol, we investigated NR3C1 expression and the association of NR3C1 genotypes with cocaine use, addiction and comorbid psychiatric symptoms in 126 chronic cocaine users and 98 stimulant-naïve healthy controls...

Mobile phone addiction has attracted much attention recently and is showing similarity to other substance use disorders. Because no studies on mobile phone addiction had yet been conducted in Spain, we developed and validated a questionnaire (Cuestionario de Abuso del Teléfono Móvil, ATeMo) to measure mobile phone abuse among young adults in Spanish. The ATeMo questionnaire was designed based on relevant DSM-5 diagnostic criteria and included craving as a diagnostic symptom. Using stratified sampling, the ATeMo questionnaire was administered to 856 students (mean age 21, 62% women)...

Alcohol (ethanol, EtOH) is one of the most widely abused drugs with profound effects on brain function and behavior. GABAA receptors (GABAA Rs) are one of the major targets for EtOH in the brain. Temporary plastic changes in GABAA Rs after withdrawal from a single EtOH exposure occur both in vivo and in vitro , which may be the basis for chronic EtOH addiction, tolerance and withdrawal symptoms. Extrasynaptic δ-GABAA R endocytosis is implicated in EtOH-induced GABAA R plasticity, but the mechanisms by which the relative abundance and localization of specific GABAA Rs are altered by EtOH exposure and withdrawal remain unclear...

BACKGROUND: Alcohol use-particularly unhealthy alcohol use-exacerbates risks associated with Hepatitis C virus (HCV). However, whether unhealthy alcohol use is appropriately addressed among HCV+ patients is understudied. We examined receipt of alcohol-related care among HCV+ patients and unhealthy alcohol use. METHODS: All positive alcohol screens (AUDIT-C score ≥5) documented 10/01/09-5/30/13 were identified from national electronic health records data from the Veterans Health Administration (VA)...
