Abstract
Military personnel are often exposed to high altitude (HA, ca. 4500-5000m) for combat operations associated with neurological dysfunctions. HA is a severe stressful situation and people frequently use methamphetamine (METH) or other psychostimulants to cope stress. Since military personnel are prone to different kinds of traumatic brain injury (TBI), in this review we discuss possible effects of METH on concussive head injury (CHI) at HA based on our own observations. METH exposure at HA exacerbates pathophysiology of CHI as compared to normobaric laboratory environment comparable to sea level. Increased blood-brain barrier (BBB) breakdown, edema formation and reductions in the cerebral blood flow (CBF) following CHI were exacerbated by METH intoxication at HA. Damage to cerebral microvasculature and expression of beta catenin was also exacerbated following CHI in METH treated group at HA. TiO2-nanowired delivery of H-290/51 (150mg/kg, i.p.), a potent chain-breaking antioxidant significantly enhanced CBF and reduced BBB breakdown, edema formation, beta catenin expression and brain pathology in METH exposed rats after CHI at HA. These observations are the first to point out that METH exposure in CHI exacerbated brain pathology at HA and this appears to be related with greater production of oxidative stress induced brain pathology, not reported earlier.

Abstract
BACKGROUND Psychocutaneous disorders are often attributed to stimulant medications, yet this relationship has never been fully elucidated. Literature on psychocutaneous disorders largely focuses on clinical presentation and treatment rather than disease etiology or exacerbation. OBJECTIVE To determine whether patients presenting with psychocutaneous disorders display high rates of stimulant use and psychiatric comorbidity. METHODS We undertook a retrospective cohort study of patients with psychocutaneous disorders presenting to a single center. It was hypothesized that these patients would have high rates of stimulant use and psychiatric comorbidity. Following analysis of baseline demographics, the patients were assigned to 1 of 2 groups: those with a psychotic disorder and those with a neurotic disorder. RESULTS Sixty percent of the patients (n = 317) with psychocutaneous disease had recently used a stimulant and more than 80% (270 of 317) carried an additional psychiatric diagnosis. The neurotic disorder group (n = 237) was younger and had higher rates of stimulant use. The psychotic disorder group (n = 80) had higher rates of psychosis, medical comorbidity, and illicit stimulant drug use. LIMITATIONS The predominantly Caucasian population may limit generalizability of findings as may the retrospective nature. CONCLUSIONS Patients with psychocutaneous disease have high rates of stimulant use and most have at least 1 psychiatric comorbidity.

Abstract
BACKGROUND Methamphetamine use is associated with disproportionate risk of HIV infection and increased risk of depression among sexual minority men. The purpose of the study was to estimate the association between clinical depression diagnoses and sexual risk-taking among cisgender men who have sex with men (MSM) who use methamphetamine. METHOD From March 2014 through January 2016, 286 MSM who use methamphetamine but were not seeking treatment for methamphetamine use disorder were enrolled to participate in a technology-based randomized controlled trial to reduce methamphetamine use and HIV sexual risk behaviors; participants were assessed for major depressive episodes (MDE) and persistent depressive disorder (PDD) at baseline. Multivariate clustered zero-inflated negative binomial regression analyses of condomless anal intercourse (n=282; 1,248 visits) estimated the association between this baseline diagnostic result and engagement in sexual risk-taking over time. RESULTS Participants predominantly identified as non-white (80%), averaged 42 years of age, and reported a HIV prevalence rate of 46%. Engagement in sexual risk-taking consistently demonstrated a positive curvilinear relationship with clinical depression severity, such that, for example, participants without clinical depression (59% of the sample; coef.=1.16) and those with MDE (36% of the sample; coef.=1.45) both demonstrated elevated rates of condomless anal sex with anonymous partners relative to participants with PDD (5% of the sample; analytical reference category; both coef. p<0.05). Data also demonstrated a trend (p = 0.053) of reduced sexual risk-taking with main partners among participants diagnosed with MDE (coef.=-0.94). CONCLUSIONS Methamphetamine use among participants in this study inverted the functional form of the relationship between depression and sexual risk among MSM observed in prior studies. Whereas low-grade depression has been associated with increased sexual risk-taking in prior samples of MSM, methamphetamine upends this relationship, such that the greatest engagement in sexual risk-taking occurred among those diagnosed with MDE at baseline. Additional research is warranted to clarify how methamphetamine influences sexual risk-taking among MSM with/without comorbid depression.

Abstract
OBJECTIVE Chronic use of synthetic cannabinoids (SCs) has been associated with a wide range of negative consequences for health including psychotic and affective disturbances. Accumulating evidence indicates that cannabinoids use may be a risk factor for schizophrenia, and chronic natural cannabis users score higher than non-users on measures of schizotypal personality traits. However, little is known regarding the personality characteristics of SC users, especially in comparison with recreational cannabis users and healthy individuals. This study aimed to examine the differences in personality characteristics and schizotypy between SC users, regular cannabis users, and non-users and to compare these measures between groups. METHODS Forty-two chronic SC users, 39 natural cannabis users, and 47 non-using control participants, without history of mental disorder, or current substance use diagnosis (mean age 26± 4.47 years; 23 females, 105 males), completed the Big-Five Factor Inventory (BFI), the Schizotypal Personality Questionnaire-Brief (SPQ-B), substance use history, rating scales of depression and anxiety, and a demographic questionnaire. RESULTS On the BFI, SC users scored higher than natural cannabis users and non-users on neuroticism, but lower on agreeableness and extraversion, and endorsed greater schizotypal symptoms on the SPQ-B. In addition, SC users had lower scores on conscientiousness than non-users, and natural cannabis users were more extroverted than non-users. Higher openness and lower conscientiousness predicted schizotypy for both SC and natural cannabis users. Finally, greater neuroticism predicted schizotypy for natural cannabis users, and introversion predicted schizotypy for non-users. CONCLUSIONS These results show that chronic SC users differ from natural cannabis users and non-users on dimensions of specific personality traits and schizotypy that may indicate psychotic proneness.

Abstract
BACKGROUND Psychoactive substance abuse is a psychosocial disorder that its, emergence, continuation, and treatment are associated with personality factors, spiritual well-being, and social support. OBJECTIVE This study was conducted to investigate the relationship between personality traits with spiritual well-being and perceived social support in methamphetamine users undergoing treatment in 2016 in the clinics of Kermanshah City, Iran. METHODS This cross-sectional study was conducted on a sample of 117 methamphetamine users undergoing treatment in addiction clinics of Kermanshah City, Iran. The formed study population was prepared by convenience sampling according to the inclusion-exclusion criteria. Data were collected using a demographic form, NEO Five-Factor Inventory, Paloutzian and Ellison's spiritual wellbeing scale, and perceived social support inventory of Fleming et al. The collected data were analyzed by parametric and nonparametric tests in SPSS v.23. RESULTS The results showed that 82.2% of participants had a moderate level of agreeableness, 88.1% had moderate neuroticism, 93.2% had moderate extraversion, 87.2% had moderate conscientiousness, and 92.2% had a moderate level of openness to experience. In addition, 76.9% of participants had a low level of spiritual well-being and the remaining 23.1% had a moderate spiritual wellness. The mean spiritual well-being and perceived social support scores of participants were 69.94±10.86 and 33.94±7.55, respectively. The findings showed a significant relationship between personality traits and spiritual well-being and social support in methamphetamine users (p = 0.05). CONCLUSION The results indicate that personality traits, perceived social support, and spiritual wellbeing can be considered as risk factors for methamphetamine abuse.

Abstract
Prior research has identified subgroups of HIV-positive gay and bisexual men (GBM) based upon information, motivation, and behavioral skills (IMB) profiles related to HIV medication adherence and methamphetamine use. We conducted a randomized controlled trial of a combined motivational interview (MI) and cognitive behavioral therapy (CBT) intervention tailored specifically to the unique context of HIV-positive GBM, and tested whether IMB profiles moderated treatment effects. HIV-positive GBM (N = 210) were randomized to MI + CBT or an attention-matched education control. Both conditions resulted in reduced methamphetamine use, improved medication adherence (and higher CD4 and lower viral loads), and fewer acts of condomless anal sex at 3, 6, 9 and 12 months post-intervention. Furthermore, the MI + CBT condition achieved greater improvements in medication adherence for men who had greater barriers to change compared to similarly-classified men in the control condition, suggesting the importance of pre-intervention profiles for tailoring future interventions.

Abstract
Methamphetamine (MA) abuse has been rising rapidly over the past decade, however, its impact in spatial cognitive function remains unknown. To understand its effect on visuospatial ability and spatial orientation ability, 40 MA users and 40 non-MA users conducted the Simple Reaction Task (Task 1), the Spatial Orientation Task (Task 2), and the Mental Rotation Task (Task 3), respectively. There was no significant difference in either accuracy or reaction time (RT) between 2 groups in Task 1. During Task 2, in comparison with non-MA users, MA users performed poorer on RT, but not in accuracy for foot and hand stimuli. In addition, both non-MA and MA users responded much more quickly to upward stimuli than downward stimuli on vertical surface, however, only non-MA users exhibited leftward visual field advantage in horizontal orientation processing. As for Task 3, MA users exhibited poorer performance and more errors than their healthy counterparts. For each group, linear relationship was revealed between RT and orientation angle, whereas MA abuse led to longer intercept for all stimuli involved. Our findings suggested that MA abuse may lead to a general deficit in the visuospatial ability and the spatial orientation ability with more serious impact in the former.

Following Lives Undergoing Change (Flux) study: Implementation and baseline prevalence of drug use in an online cohort study of gay and bisexual men in Australia. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2017; 41:41-50.

Abstract
BACKGROUND Drug use among gay and bisexual men (GBM) is higher than most populations. The use of crystal methamphetamine, erectile dysfunction medication (EDM), and amyl nitrite have been associated with sexual risk behaviour and HIV infection among gay and bisexual men (GBM). OBJECTIVE This paper describes an online prospective observational study of licit and illicit drug use among GBM and explores baseline prevalence of drug use in this sample. Capturing these data poses challenges as participants are required to disclose potentially illegal behaviours in a geographically dispersed country. To address this issue, an entirely online and study specific methodology was chosen. METHODS Men living in Australia, aged 16.5 years of age or older, who identified as homosexual or bisexual or had sex with at least one man in the preceding 12 months were eligible to enrol. RESULTS Between September 2014 and July 2015, a total of 2250 participants completed the baseline questionnaire, of whom, 1710 (76.0%) consented to six-monthly follow-up. The majority (65.7%) were recruited through Facebook targeted advertising. At baseline, over half (50.5%) the men reported the use of any illicit drug in the previous six months, and 28.0% had used party drugs. In the six months prior to enrolment, 12.0% had used crystal methamphetamine, 21.8% had used EDM, and 32.1% had used amyl nitrite. Among the 1710 men enrolled into the cohort, 790 men had used none of these drugs. CONCLUSION Ease of entry and minimal research burden on participants helped ensure successful recruitment into this online cohort study. Study outcomes will include the initiation and cessation of drug use, associated risk behaviours, and health consequences, over time. Results will provide insights into the role gay community plays in patterns of drug use among GBM.

Abstract
OBJECTIVE In recent years, increasing intravenous mephedrone use was reported in several countries. The aim of this study was to describe the characteristics of such a form of mephedrone use, while identifying the differences between injectors and non-injectors in patterns of mephedrone use and psychiatric symptom status. METHODS One hundred and forty-five mephedrone users were surveyed on patterns of mephedrone use using a structured questionnaire as well as the Brief Symptom Inventory. RESULTS Majority of users received mephedrone from acquaintances and used it in discos/parties settings regarding both first and current mephedrone use. Intranasal use was the most typical route of administration (84.4%). Injectors (11%) used the drug more frequently and in higher dosages. This group included a greater proportion of opiate users (37.5%) and showed more diffuse psychiatric symptoms. Regarding the predictors of being an injector, heroin use showed the highest odds ratio. CONCLUSIONS Intravenous mephedrone use is associated with a higher risk of harmful drug use, elevated psychiatric symptom profile and increased possibility of mephedrone being considered as an addictive substance. These findings might be important in efficient treatment planning.

Abstract
BACKGROUND It is particularly important to survey substance use trends in populations most impacted by the consequences of substance use. Men who have sex with men (MSM) exhibit rates of methamphetamine and other substance use that exceeds those observed among other populations in the United States. Such substance use has been associated with numerous negative health sequelae. METHODS An outreach program performed street encounters with 5599 unique substance-using MSM from January 1, 2008 through December 31, 2011 to collect data on self-reported sociodemographics and recent substance use. Data were aggregated into six-month cohorts for comparisons of recent substance use patterns across time RESULTS Participants averaged 33 years of age (SD=8), most were Caucasian/white (47%) or Hispanic/Latino (32%), and the self-reported HIV seroprevalence rate was 13.4%. Across cohorts, reported use of alcohol (range=91-93%), marijuana (range=36-46%), and/or methamphetamine (range=23-27%) was common; prevalence of amyl nitrite (max=14%), ecstasy (max=12%), powder cocaine (max=8%) and/or crack cocaine (max=4%) use, although less common, were still elevated relative to the United States general population. CONCLUSIONS Methamphetamine and other substance use remained common among substance-using MSM, demonstrating the need for continued substance use interventions geared toward this high-risk population.

Antisocial personality disorder predicts methamphetamine treatment outcomes in homeless, substance-dependent men who have sex with men. J Subst Abuse Treat 2013; 45:266-72. [PMID: 23579078 DOI: 10.1016/j.jsat.2013.03.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2012] [Revised: 02/26/2013] [Accepted: 03/05/2013] [Indexed: 11/23/2022]
Abstract
One-hundred-thirty-one homeless, substance-dependent MSM were enrolled in a randomized controlled trial to assess the efficacy of a contingency management (CM) intervention for reducing substance use and increasing healthy behavior. Participants were randomized into conditions that either provided additional rewards for substance abstinence and/or health-promoting/prosocial behaviors ("CM-full"; n=64) or for study compliance and attendance only ("CM-lite"; n=67). The purpose of this secondary analysis was to determine the affect of ASPD status on two primary study outcomes: methamphetamine abstinence, and engagement in prosocial/health-promoting behavior. Analyses revealed that individuals with ASPD provided more methamphetamine-negative urine samples (37.5%) than participants without ASPD (30.6%). When controlling for participant sociodemographics and condition assignment, the magnitude of this predicted difference increases to 10% and reached statistical significance (p<.05). On average, participants with ASPD earned fewer vouchers for health-promoting/prosocial behaviors than participants without ASPD ($10.21 [SD=$7.02] versus $18.38 [SD=$13.60]; p<.01). Participants with ASPD displayed superior methamphetamine abstinence outcomes regardless of CM schedule; even with potentially unlimited positive reinforcement, individuals with ASPD displayed suboptimal outcomes in achieving health-promoting/prosocial behaviors.

Abstract
Epidemiological studies have found that young men who have sex with men (YMSM) represent the majority of young people infected with HIV annually in the United States. Further, they are one of the few risk groups to show an increase in the rate of infections in recent years. In addition to these disparities in prevalence and infection rates, there is an inequity in prevention and intervention research on this population. The purpose of this article is to review the existing YMSM literature on HIV epidemiology, correlates of risk, and intervention research. The article concludes that promising future directions for basic research include a focus on multiple clustering health issues, processes that promote resiliency, the role of family influences, and the development of parsimonious models of risk. In terms of intervention research, the article suggests that promising future directions include Internet-based intervention delivery, integration of biomedical and behavioral approaches, and interventions that go beyond the individual level to address partnership, structural, community, and network factors.

Abstract
Evidence documents elevated rates of various types of drug use among people with posttraumatic stress disorder (PTSD). However, relatively little research has specifically examined crystal methamphetamine (CM) use among individuals with PTSD. The present study examined the relation between PTSD diagnostic status, PTSD symptom severity within symptom type clusters, and CM use histories among traumatic event-exposed individuals with versus without PTSD. Consistent with expectations, individuals with PTSD were significantly more likely to report CM use than trauma-exposed individuals without PTSD. Additionally, CM users with PTSD reported a longer duration of CM use than trauma-exposed CM users without PTSD. Finally, PTSD avoidance and hyperarousal symptoms, but not re-experiencing, were related to CM use. The potential clinical and research implications of the findings are discussed.
