When "Chems" Meet Sex: A Rising Phenomenon Called "ChemSex"

Drug-facilitated sexual assault in youth nightlife contexts in Spain

OBJECTIVES

This study aimed to provide epidemiological information on drug-facilitated sexual assault in Spanish youth partying, with a focus on prevalence rates and associated sociodemographic factors.

STUDY DESIGN

Cross-sectional study.

METHODS

Quota sampling was used to recruit 1601 young people aged 18-35 years in Spain from a digital panel. A validated questionnaire on drug-facilitated sexual assault was used to assess five types of lifetime victimisation experiences while partying. Chi-square and the exact Fisher tests were used to describe the prevalence of victimisation, drug use patterns, and perpetrator profiles. Generalised ordered logistic regression was used to explore factors associated with victimisation, analysed by gender.

RESULTS

Half of young women and one-quarter of young men had experienced drug-facilitated sexual assault in their lifetime. Female victimisation due to touching and kissing was notably high, whereas men comprised almost half of the victims of more invasive DFSA experiences involving masturbation, penetration, and oral sex. Opportunism prevailed as the assault tactic, consisting of taking advantage of the victims' incapacity derived from voluntary alcohol use. Among women, risk of victimisation was associated with a lower education level, foreign-born status, and being non-heterosexual. Male victimisation risk was highest among non-heterosexual men.

CONCLUSIONS

Drug-facilitated sexual violence in youth nightlife contexts is a serious public health issue in Spain, which requires urgent action. Most assaults involve taking advantage of victims who are incapacitated by the effects of voluntary alcohol consumption. This sexual violence primarily affects women with lower educational levels or those who are foreign-born and non-heterosexual men and women.

Feasibility, acceptability, and perceived usefulness of a community-evidence-based harm reduction intervention for sexualized stimulant use among Mexican gay, bisexual, and other men who have sex with men

BACKGROUND

The use of stimulants and other substances with the purpose of enhancing, maintaining, and prolonging sexual activity is known as sexualized substance use. Also known as chemsex, this pattern of use has been mainly explored in high-income countries. The aim of this article was to assess the feasibility, acceptability, and usefulness of a community- evidence-based harm reduction intervention among Mexican gay, bisexual, and other men who have sex with men (gbMSM) adults who reported sexualized stimulant use in the past 6 months and who were not enrolled in any psychosocial treatment.

METHODS

The in-person intervention was designed in partnership with gbMSM who used substances. It consisted of 39 harm reduction strategies before, during, and after episodes of use. The components of the intervention were health and self-care, safety, and psychopharmacology. The intervention was delivered at a university campus, a public recreational space, and an HIV public clinic. Feasibility to deliver the intervention was assessed based on enrolment and completion rates; acceptability through a 28-item, 5-point Likert scale (140 max.) constructed and validated for the Mexican population with good reliability coefficients; usefulness through a 5-point Likert scale ("not useful"-"very useful") for each of the 39 strategies; and potential behavioral change by subtracting the likelihood of implementing each strategy minus the frequency of use of the technique before the intervention.

RESULTS

Participants (n = 19; recruitment rate = 35.2%; completion rate = 84.2%) rated the intervention as acceptable with a mean score of 121.6 (SD = 7.5). The highest potential for behavioral change was regarding the use of information about the half-life of stimulants, polysubstance use, and overdose prevention.

CONCLUSIONS

This intervention is feasible when provided within public health services where potential participants are already in contact. Harm reduction strategies need to surpass sexually transmitted infections prevention and HIV care and focus on substance use and mental health strategies.

Chemsex among men who have sex with men during the Mpox health crisis in Brazil: A nationwide web survey

OBJECTIVE

To understand the factors associated with the practice of chemsex among MSM in Brazil, especially during the Mpox health crisis, and to design effective prevention and intervention strategies specifically for this population.

DESIGN

A cross-sectional and analytical study using an electronic survey, conducted from September to December 2022, during the peak of the Mpox outbreak in Brazil.

SAMPLE

A total of 1452 MSM aged 18 and older.

MEASUREMENTS

Data were collected via the REDCap platform through a survey with 46 questions. These addressed demographic data, sexual affiliations, practices, experiences with Mpox, healthcare service usage, and stigma or fear related to Mpox.

RESULTS

The prevalence of chemsex was 19.42% (n = 282). Multivariate Poisson modeling indicated a high incidence of chemsex among those diagnosed with Mpox and those involved in high-risk behaviors. The practice of chemsex was six times higher among those diagnosed with Mpox (95% CI: 4.73-9.10). MSM who engage in bugchasing had a prevalence twice that of the main outcome (95% CI: 1.31-3.16).

CONCLUSION

There is a significant need for targeted interventions for MSM in Brazil, especially given the Mpox outbreak. This study highlights the strong relationships between chemsex, experiences with Mpox, and various sexual behaviors, underscoring the importance of effective public health initiatives.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco

BACKGROUND

Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity.

METHODS

Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy).

RESULTS

There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10).

CONCLUSIONS

Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

[Chemsex: Harm reduction and support for users]

The phenomenon of chemsex, or the use of psychoactive substances in a sexual context, is increasing in communities of men who have sex with men (MSM), and carry along significant risks and consequences. No specific treatment approach has yet been established, but risk and harm reduction strategies are at the forefront. Multi-disciplinary treatment, care and support need to be based on a non-judgmental attitude, offered by trained professionals who take into account the cultural specificities of users.

Attitudes of Gay, Bisexual, and Other Men Who Have Sex with Men (GBM) toward Their Use of Amphetamine-Type Stimulants and Relation to Reducing Use in Three Canadian Cities

BACKGROUND

We explored attitudes of gay, bisexual, and other men who have sex with men (GBM) toward their amphetamine-use and associations with reduced use over time.

METHODS

We recruited sexually-active GBM aged 16+ years in Montreal, Toronto, and Vancouver, Canada, from 02-2017 to 08-2019, with follow-up visits every 6-12 months until November 2020. Among participants who reported past-six-month (P6M) amphetamine-use at enrollment, we used logistic regression to identify demographic, psychological, social, mental health, other substance-use, and behavioral factors associated with reporting needing help reducing their substance-use. We used mixed-effects logistic regression to model reduced P6M amphetamine-use with perceived problematic-use as our primary explanatory variable.

RESULTS

We enrolled 2,449 GBM across sites. 15.5-24.7% reported P6M amphetamine-use at enrollment and 82.6 - 85.7% reported needing no help or only a little help in reducing their substance use. Reporting needing a lot/of help or completely needing help in reducing substance-use was associated with group sex participation (AOR = 2.35, 95%CI:1.25-4.44), greater anxiety symptomatology (AOR = 2.11, 95%CI:1.16-3.83), greater financial strain (AOR = 1.35, 95%CI:1.21-1.50), and greater Escape Motive scores (AOR = 1.07, 95%CI:1.03-1.10). Reductions in P6M amphetamine-use were less likely among GBM who perceived their amphetamine-use as problematic (AOR = 0.17 95% CI 0.10 - 0.29).

CONCLUSIONS

Most amphetamine-using GBM did not feel they needed help reducing their substance use, and many reported reduced amphetamine-use at subsequent visits. Those who perceived their use as problematic were less likely to reduce their use. Further interventions to assist GBM in reducing their use are needed to assist those who perceive their use as problematic.

Methamphetamine (MA) use and MA-induced psychosis are associated with increasing aberrations in the compensatory immunoregulatory system, interleukin-1α, and CCL5 levels

There are only a few studies reporting on the immunological profiles of methamphetamine (MA) use, MA dependency, or MA-induced psychosis (MAP). This study measured M1 macrophage, T helper (Th)-1, Th-2, growth factor, and chemokine profiles, as well as the immune inflammatory response system (IRS) and compensatory immunoregulatory system (CIRS) in peripheral blood samples from patients with MA use (n = 51), MA dependence (n = 47), and MAP (n = 43) in comparison with controls (n = 32). We discovered that persistent MA use had a robust immunosuppressive impact on all immunological profiles. The most reliable biomarker profile of MA use is the combination of substantial CIRS suppression and a rise in selected pro-inflammatory cytokines, namely CCL27 (CTACK), CCL11 (eotaxin), and interleukin (IL)-1α. In addition, MA dependency is associated with increased immunosuppression, as demonstrated by lower stem cell factor levels and higher IL-10 levels. MAP is related to a significant decrease in all immunological profiles, particularly CIRS, and an increase in CCL5 (RANTES), IL-1α, and IL-12p70 signaling. In conclusion, long-term MA use and dependency severely undermine immune homeostasis, whereas MAP may be the consequence of increased IL-1α - CCL5 signaling superimposed on strongly depleted CIRS and Th-1 functions. The widespread immunosuppression established in longstanding MA use may increase the likelihood of infectious and immune illness or exacerbate disorders such as hepatitis and AIDS. Furthermore, elevated levels of CCL5, CCL11, CCL27, IL-1α, and/or IL-12p70 may play a role in the peripheral (atherosclerosis, cutaneous inflammation, immune aberrations, hypospermatogenesis) and central (neuroinflammation, neurotoxic, neurodegenerative, depression, anxiety, and psychosis) side effects of MA use.

Hyperconnectivity of the lateral amygdala in long-term methamphetamine abstainers negatively correlated with withdrawal duration

Introduction: Several studies have reported structural and functional abnormalities of the amygdala caused by methamphetamine addiction. However, it is unknown whether abnormalities in amygdala function persist in long-term methamphetamine abstainers. Methods: In this study, 38 long-term male methamphetamine abstainers (>12 months) and 40 demographically matched male healthy controls (HCs) were recruited. Considering the heterogeneous nature of the amygdala structure and function, we chose 4 amygdala subregions (i.e., left lateral, left medial, right lateral, and right medial) as regions of interest (ROI) and compared the ROI-based resting-state functional connectivity (FC) at the whole-brain voxel-wise between the two groups. We explored the relationship between the detected abnormal connectivity, methamphetamine use factors, and the duration of withdrawal using correlation analyses. We also examined the effect of methamphetamine use factors, months of withdrawal, and sociodemographic data on detected abnormal connectivity through multiple linear regressions. Results: Compared with HCs, long-term methamphetamine abstainers showed significant hyperconnectivity between the left lateral amygdala and a continuous area extending to the left inferior/middle occipital gyrus and left middle/superior temporal gyrus. Abnormal connections negatively correlated with methamphetamine withdrawal time (r = -0.85, p < 0.001). The linear regression model further demonstrated that the months of withdrawal could identify the abnormal connectivity (βadj = -0.86, 95%CI: -1.06 to -0.65, p < 0.001). Discussion: The use of methamphetamine can impair the neural sensory system, including the visual and auditory systems, but this abnormal connectivity can gradually recover after prolonged withdrawal of methamphetamine. From a neuroimaging perspective, our results suggest that withdrawal is an effective treatment for methamphetamine.

Substance abuse and male sexual dysfunction: what lies beneath?

INTRODUCTION

Substance abuse has become a worldwide health problem, leading to numerous consequences such as social problems among family members, abnormal behavior, adverse health effects, and psychological problems as well as economic consequences.

OBJECTIVES

We sought to assess the relationship between substance abuse and male sexual health.

METHODS

A search was carried out in the following databases: PubMed, MeSH (Medical Subject Headings), Science Direct, Scopus, Cochrane Library, EMBASE, CINAHL, Academic Search Complete, and the Egyptian Knowledge Bank. The following keywords were used to assess the outcomes for relevant associations: illicit drugs, addiction, substance abuse, sexual health, erectile dysfunction, ejaculatory disorders, impotence, orgasm disorders, and sexual performance.

RESULTS

The initial literature search identified a total of 148 articles in all searched databases. After removal of duplicate studies and application of inclusion/exclusion criteria, 75 reported studies were retained for review, including 38 case-control studies and 37 cross-sectional studies. These articles were classified into the following categories according to the type of abused substance addressed: cannabis/marihuana, 16 articles; opioids, 13 articles; heroin, 11 articles; cocaine, 5 articles; tramadol, 6 articles; ketamine, 2 articles; ecstasy, 4 articles; amphetamine, 2 articles; khat, 7 articles; androgen anabolic steroids, 2 articles; and polydrugs, 7 articles. Most of these recruited articles demonstrated a negative impact of the addressed substance on male sexual health, with variable levels.

CONCLUSION

Substance abuse has negative impacts on male sexual health that should be addressed. More studies conducted with proper methodological and statistical approaches, including logistic regression analysis, are needed to predict the effects of specific substances, considering the rapidly growing effects of non-substance-use disorders on male sexual health.

Prevalence and development of a risk score for oral human papillomavirus infection in men who have sex with men in Mexico

BACKGROUND

Men who have sex with men (MSM) are at high risk for oral human papillomavirus (HPV infection). There are no specific screening guidelines to facilitate the identification of people at risk for oral HPV infection. We aimed to estimate the prevalence of oral high-risk HPV and create a risk score to identify MSM at higher risk for prevalent oral HPV.

METHODS

We collected baseline data from a clinical trial from a subsample of 500 MSM attending sexually transmitted disease treatment clinics; they provided an oral gargle sample for high-risk HPV detection. We calculated oral high-risk HPV prevalence and 95% confidence intervals (CIs), used a logistic regression model to identify factors associated with high-risk HPV infection, and created a risk score.

RESULTS

The prevalence of any oral high-risk HPV among MSM was 11.1% (95% CI: 8.6-14.2), with a higher prevalence observed among men living with HIV (14.8%). Factors independently associated with oral high-risk HPV were age ≥40 years (OR = 2.71, 95% CI: 1.28-5.73 compared to <40 years), being HIV-positive with CD4 count 200-499 (OR = 2.76, 95% CI: 1.34-5.65 compared to HIV-negative), and recent recreational use of vasodilators (poppers/sildenafil) (OR = 2.02, 95% CI: 1.02-2.97). The risk score had good discriminatory power (AUC = 0.70, 95% CI: 0.63-0.77).

CONCLUSIONS

MSM have specific predictors for prevalent oral high-risk HPV, and a risk score could be used by clinicians to target men with vaccine recommendations and counseling, and identify those who could benefit from primary interventions given the available resources, or for referral to dental services for follow-up when available.

An mHealth-Delivered Sexual Harm Reduction Tool (PartyPack) for Men Who Have Sex With Men in Malaysia: Usability Study

BACKGROUND

Chemsex-the use of psychoactive drugs to enhance the sexual experience-is an increasing phenomenon globally. Despite the increasing burden and associated harms of chemsex, evidence-based interventions (ie, behavioral and pharmacological) for chemsex users are nonexistent.

OBJECTIVE

In this study, we assessed the usability and acceptability of a mobile health (mHealth)-delivered safer chemsex package ("PartyPack") as a sexual harm reduction strategy among men who have sex with men in Malaysia-a setting where chemsex is becoming increasingly prevalent.

METHODS

This study is part of a larger smartphone app-based intervention (ie, JomPrEP; University of Connecticut) designed to improve access to HIV prevention services among Malaysian men who have sex with men. A total of 50 participants were recruited from the Greater Kuala Lumpur region of Malaysia to use the JomPrEP app, which included a feature allowing participants to order PartyPack, for 30 days (March-April 2022). The usability and acceptability of the PartyPack were assessed using self-report, app analytics, and exit interviews (n=20).

RESULTS

Overall, 8% (4/50) of participants reported having engaged in chemsex in the past 6 months; however, engagement in condomless sex (34/50, 68%) and group sex (9/50, 18%) was much higher. A total of 43 (86%) participants ordered PartyPack, of which 27 (63%) made multiple orders during the 30 days. Most participants (41/43, 95%) reported being satisfied with the PartyPack order feature in the app, with 91% (39/43) indicating the order and tracking process was easy. Thematic data exploration further revealed important information for understanding (eg, items included in the package, use of mHealth platform to order package, and discreetness of the PartyPack box and order and delivery) and refining the logistical preferences (eg, using branded items and allowing customization during order).

CONCLUSIONS

Our findings provide strong evidence of the usability and acceptability of a mHealth-delivered safer chemsex package as a potential sexual harm reduction tool among this underserved population. Replication in a study with a larger sample size to test the efficacy of the PartyPack is warranted.

Stimulant Use Associated With Psychosocial Factors, HIV Risk, and Concurrent Hazardous Alcohol Use Among US Adults: Exploratory Cross-Sectional Questionnaire Study

BACKGROUND

Stimulant use is a major public health problem that contributes to morbidity and mortality among men who have sex with men (MSM) in the United States. To reduce the harms associated with stimulant use, there is a need to identify the factors associated with stimulant use to inform interventions. Additionally, there is a need to use large crowdsourcing platforms like Amazon Mechanical Turk (MTurk) to engage more individuals who use substances across the United States.

OBJECTIVE

We identified the correlates of stimulant use among people who use alcohol or stimulants in the United States recruited using MTurk.

METHODS

Participants who were aged ≥18 years in the United States and reported alcohol or stimulant (ie, cocaine, crack cocaine, and methamphetamine) use were deemed eligible and recruited via the web platform MTurk. Participants completed a baseline survey, which assessed sociodemographics, psychosocial (ie, depression, affect, self-esteem, and stress) factors, substance use, and sexual behaviors. Data were collected and analyzed with STATA (version 17; StataCorp). Stratifying by MSM status, bivariate and multivariable logistic regression models were built in STATA to examine the correlates of stimulant use. Multivariable models controlled for age, race, health insurance, and relationship status.

RESULTS

Of 272 participants, 201 (73.9%) identified as male, 134 (49.2%) were MSM, 52 (19.1%) were from racial and ethnic minoritized communities, and 158 (58%) were in a relationship. The mean age was 36.10 (SD 10.3) years. A total of 40 (14.7%) participants reported stimulant use in the past 6 months. Factors significantly associated with stimulant use were being MSM (adjusted odds ratio [aOR] 4.61, 95% CI 1.97-10.81), a higher Alcohol Use Disorders Identification Test-Concise score (aOR 1.24, 95% CI 1.08-1.42), more intense cravings for alcohol in the past 24 hours (aOR 1.03, 95% CI 1.01-1.04), a higher depression score (aOR 1.06, 95% CI 1.01-1.12), a greater number of male partners in the last 6 months (aOR 1.32, 95% CI 1.08-1.61), a greater number of female partners in the last 6 months (aOR 1.42, 95% CI 1.04-1.92), and being diagnosed with a sexually transmitted infection (eg, syphilis, gonorrhea, chlamydia, herpes simplex virus, human papillomavirus, and other) in the last 6 months (aOR 14.61, 95% CI 3.45-61.87). Additionally, there was a significant additive interaction between MSM status and negative affect, such that the impact of negative affect on stimulant use was significantly greater among MSM compared with non-MSM (relative excess risk due to interaction 0.085, 95% CI 0.037-0.13).

CONCLUSIONS

Interventions that address stimulant use should use evidence-based approaches that reduce negative affect, depression, and cravings for alcohol. Additionally, interventions should be customized for MSM populations.

Comparing Factors Associated with Increased Stimulant Use in Relation to HIV Status Using a Machine Learning and Prediction Modeling Approach

Stimulant use is an important driver of HIV/STI transmission among men who have sex with men (MSM). Evaluating factors associated with increased stimulant use is critical to inform HIV prevention programming efforts. This study seeks to use machine learning variable selection techniques to determine characteristics associated with increased stimulant use and whether these factors differ by HIV status. Data from a longitudinal cohort of predominantly Black/Latinx MSM in Los Angeles, CA was used. Every 6 months from 8/2014-12/2020, participants underwent STI testing and completed surveys evaluating the following: demographics, substance use, sexual risk behaviors, and last partnership characteristics. Least absolute shrinkage and selection operator (lasso) was used to select variables and create predictive models for an interval increase in self-reported stimulant use across study visits. Mixed-effects logistic regression was then used to describe associations between selected variables and the same outcome. Models were also stratified based on HIV status to evaluate differences in predictors associated with increased stimulant use. Among 2095 study visits from 467 MSM, increased stimulant use was reported at 20.9% (n = 438) visits. Increased stimulant use was positively associated with unstable housing (adjusted [a]OR 1.81; 95% CI 1.27-2.57), STI diagnosis (1.59; 1.14-2.21), transactional sex (2.30; 1.60-3.30), and last partner stimulant use (2.21; 1.62-3.00). Among MSM living with HIV, increased stimulant use was associated with binge drinking, vaping/cigarette use (aOR 1.99; 95% CI 1.36-2.92), and regular use of poppers (2.28; 1.38-3.76). Among HIV-negative MSM, increased stimulant use was associated with participating in group sex while intoxicated (aOR 1.81; 95% CI 1.04-3.18), transactional sex (2.53; 1.40-2.55), and last partner injection drug use (1.96; 1.02-3.74). Our findings demonstrate that lasso can be a useful tool for variable selection and creation of predictive models. These results indicate that risk behaviors associated with increased stimulant use may differ based on HIV status and suggest that co-substance use and partnership contexts should be considered in the development of HIV prevention/treatment interventions.

Starting the Discussion: A Call to Enhance Care for People With Stimulant Use Disorder

Stimulant use disorder (StUD) significantly contributes to substance-related morbidity and mortality in the United States. Overshadowed by the country's focus on opioid-related overdose deaths, stimulant and stimulant/opioid overdose deaths have increased dramatically over the last decade. Many individuals who use stimulants illicitly or have StUD have multiple, intersecting stigmatized characteristics which exacerbate existing barriers and create new obstacles to attaining addiction treatment. Illicit stimulant use, StUD, and stimulant-related overdose disproportionately impact minoritized racial and gender, and sexuality diverse groups. Historically, people who use illicit stimulants and those with StUD have been highly stigmatized, criminalized, and overly ignored by health care providers, policymakers, and the public compared to people who use other drugs and alcohol. As a result, most people needing treatment for StUD do not receive it. This is partly due to the lack of evidence-based treatment for StUD, which has resulted in few programs specializing in the care of people with StUD. The lack of available treatment is compounded by high rates of StUD in marginalized groups already reluctant to engage with the health care system. As health care professionals, we can improve outcomes for people with StUD by changing how we talk about, document, and respond to illicit stimulant use, related characteristics, behaviors, and social and structural determinants of health. To do this, we must seek to understand the lived realities of people with StUD and illicit stimulant use and use this knowledge to amend existing models of care.

An uncharted territory of sexualized drug use: exploring the dynamics of chemsex among young and adolescent MSM including self-identified gay men in urban Dhaka, Bangladesh

Global and local literature depicted the pervasiveness of chemsex among men who have sex with men (MSM), yet there is limited evidence on adolescents and youth. Though literature showed their engagement in chemsex, further exploration is warranted about their socio-sexual contexts and implications. Therefore, this article explored the contexts and implications of chemsex on young and adolescent MSM. This article is extracted from qualitative research evidence, and research data are triangulated by programmatic evidence on adolescent and young MSM from two ongoing pilot interventions. The key motivational factors for engaging in chemsex were primarily rooted in the dynamics of their peer networks. Specifically, the onset of drug use is predominantly attributed to curiosity toward experimentation with methamphetamine, peer influence, propensity to lose weight, and increasing courage to approach potential sexual partners. Moreover, they continued taking drugs as it enhanced their sexual performance, thus perpetuating chemsex. Additionally, the findings revealed several sexual implications of methamphetamine, e.g., bolstering their sexual "stamina," increasing their propensity toward sexual violence, and reducing their decision-making abilities and judgment, thus collectively decreasing condom use. In essence, chemsex is considerably driven by their socio-sexual contexts, thus perpetuating sexual risk behaviors and compromising sexual health outcomes. Therefore, harm reduction interventions targeted need to be designed keeping in mind their socio-sexual dynamics and age.

Chemsex and Sexual Well-Being in Young Polish Men

Chemsex refers to the use of psychoactive drugs for sexual purposes-before or during sex. This phenomenon mainly affects men, in particular those belonging to the LGBTQIA+ (lesbian, gay, bisexual, transgender, intersex, queer/questioning, asexual, and more diverse individuals) community. From the perspective of the transactional theory of stress, chemsex can be considered a strategy for coping with stress, which is why it is also extremely important to verify its role in functioning outside the sexual sphere. For this reason, this study verified the relationship between the use of chemsex, perceived stress, sexual well-being, and life satisfaction in young Polish men. The study involved 175 men (67 people using chemsex and 108 people in the control group) between 18 and 33 years of age. The Perceived Stress Scale, the Short Scale of Sexual Well-being, the Satisfaction with Life Scale, and the authors' questionnaire about the use of chemsex were used. It was observed that individuals using chemsex showed a significantly lower level of sexual well-being and satisfaction with life (moderate effects) and a higher level of perceived stress (strong effect) when compared to the control group not using psychoactive substances. Additionally, a positive and moderate relationship was observed between the number of psychoactive substances used and perceived stress in the group of individuals using chemsex. Moreover, the number of substances used and the level of perceived stress were negatively and moderately related to the level of well-being in these individuals. It was also shown that perceived stress was a significant predictor of the number of psychoactive substances used before and during sex and that perceived stress and the number of psychoactive substances used were significant and negative predictors of life satisfaction and sexual well-being, explaining a large portion of their variance.

Trends in drug use among nightclub and festival attendees in New York City, 2017-2022

BACKGROUND

Drug use is prevalent among people who attend electronic dance music (EDM) parties at nightclubs or festivals. This population can serve as a sentinel population to monitor trends in use of party drugs and new psychoactive substances (NPS) that may diffuse through larger segments of the population.

METHODS

We surveyed adults entering randomly selected EDM parties at nightclubs and dance festivals in New York City about their drug use in 2017 (n=954), 2018 (n=1,029), 2019 (n=606), 2021 (n=229), and 2022 (n=419). We estimated trends in past-year and past-month use of 22 drugs or drug classes based on self-report from 2017-2022 and examined whether there were shifts pre- vs. post-COVID (2017-2019 vs. 2021-2022).

RESULTS

Between 2017 and 2022, there were increases in past-year and past-month use of shrooms (psilocybin), ketamine, poppers (amyl/butyl nitrites), synthetic cathinones ("bath salts"), and novel psychedelics (lysergamides and DOx series), increases in past-year cannabis use, and increases in past-month use of 2C series drugs. Between 2017 and 2022, there were decreases in past-year heroin use and decreases in past-month cocaine use, novel stimulant use, and nonmedical benzodiazepine use. The odds of use of shrooms, poppers, and 2C series drugs significantly increased after COVID, and the odds of use of cocaine, ecstasy, heroin, methamphetamine, novel stimulants, and prescription opioids (nonmedical use) decreased post-COVID.

CONCLUSIONS

We estimate shifts in prevalence of various drugs among this sentinel population, which can inform ongoing surveillance efforts and public health response in this and the general populations.

Risk assessment of human mpox infections: Retrospective cohort study

OBJECTIVES

The global supply of vaccines against mpox (previously called monkeypox virus infection) was significantly lower than the demand. Therefore, evidence-based vaccine prioritization criteria, based on risk assessment were needed. Our objective was therefore to identify the characteristics of individuals at the highest risk for mpox.

METHODS

This population-based cohort study included all Clalit Health Services (CHS) subjects assumed to be at risk for mpox. The eligibility criteria for inclusion were determined based on known characteristics of people with infection worldwide and insights of LGBTQ+ -specialized CHS clinicians. Cox hazards models were used to identify risk factors for mpox within the study cohort. The study commenced on June 6, 2022, the date of the first known mpox in CHS members, until July 31, 2022, when the mpox vaccination campaign started.

RESULTS

8,088 individuals of 4.7 Million CHS members (0.18%) were identified according to the study inclusion criteria. Of those, 69 (0.85%) developed infection during the study period. Risk factors for mpox were birth in 1980 or later (HR 5.04 95%CI: 2.11-12.02), history of syphilis (2.62, 1.58-4.35), registeration to primary healthcare clinics in the Tel-Aviv district (2.82, 1.44-5.54), HIV-PrEP use (3.96, 2.14-7.31), PDE5 inhibitors use (2.92, 1.77-4.84), and recent STIs within the last 18 months (2.27, 1.35-3.82). No infections were observed in individuals with none of the factors. Individuals with 3+ risk factors had a 20.30-fold (10.39-39.69) higher risk for mpox compared to those with 0-2, with 85.5% (75.0% -92.8%) sensitivity and 77.8% (76.9%-78.7%) specificity.

CONCLUSION

Weighting individuals' risk levels based on validated risk factors against vaccine availability can assist health systems in the equitable prioritization of vaccine allocation in various future outbreaks, given supply-demand gaps.

Brief Report: Impact of Methamphetamine Use and Rectal STIs on Systemic and Rectal Mucosal Inflammation

BACKGROUND

Methamphetamine (MA) use is associated with sexual risk behavior as well as systemic and mucosal inflammation, suggesting parallel biological and behavioral mechanisms of HIV transmission among men who have sex with men (MSM) who use MA. Data evaluating the combined biological effects of MA use with concomitant rectal gonococcal and/or chlamydial (GC/CT) infection on inflammation are limited.

SETTING

Secondary analysis of stored rectal and plasma specimens from 100 MSM participating in an NIDA-funded longitudinal cohort in Los Angeles, CA.

METHODS

This cross-sectional analysis evaluated systemic and rectal inflammatory markers under 2 conditions: (1) recent MA use (by urine drug screen) and (2) rectal GC/CT infection. We evaluated 50 participants with recent MA use (25 with and 25 without rectal GC/CT) and 50 MSM without MA use (25 with and 25 without rectal GC/CT). Log-transformed plasma and rectal immune markers were regressed on MA exposure and rectal GC/CT, controlling for HIV status and age.

RESULTS

Median age was 32 (range 19-45) years, and 58% of participants were living with HIV. Plasma tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8, IL-1ß, and rectal IL-6 were associated with rectal GC/CT and MA use, independent of HIV status. Higher levels of rectal TNF-α, IL-1ß, and IL-17a were associated with rectal GC/CT.

CONCLUSIONS

Systemic and rectal inflammation was positively associated with rectal GC/CT and MA use. Condomless sex in the setting of GC/CT- and MA-induced immune activation may provide a basis for synergistic biobehavioral mechanisms that promote HIV/STI transmission among MSM who use MA.

The Impact of Ingroup and Outgroup Exclusion on HIV-Risk Cognitions in Sexual Minority Men

BACKGROUND

Sexual minority men (SMM) face disproportionate rates of HIV/AIDS. Emerging evidence indicates that minority stress (e.g., discrimination) and stress from within the gay community itself (e.g., exclusion) may contribute to sexual orientation disparities in HIV prevalence and risk.

PURPOSE

This study investigated the impact of sexual orientation discrimination and exclusion by the gay community on SMM's intentions to engage in HIV-risk behavior.

METHODS

We conducted an experiment in which we employed an exclusion manipulation to induce (a) perceived discrimination from the outgroup and (b) perceived exclusion by the ingroup in a community sample of 194 SMM. Participants completed a baseline assessment of previous discrimination, exposure to gay community stress, and HIV-risk behavior. Two days later, participants completed an experiment in which they were randomized to one of four conditions in the game Cyberball: (a) exclusion by straight men, (b) inclusion by straight men, (c) exclusion by gay men, or (d) inclusion by gay men. Risky sex intentions were then assessed.

RESULTS

Discrimination and gay community stress were positively associated with HIV-risk behaviors at baseline. Participants who were excluded (vs. included) by straight men in the experimental task reported more risky sex intentions. This effect was mediated by decreases in state self-esteem. Risky sex intentions did not differ between participants who were included versus excluded by gay men.

CONCLUSIONS

This study provides the first experimental evidence that discrimination is associated with sexual risk taking in SMM, and elucidates a potential psychological mechanism through which this effect operates.

Lethal Lust: Suicidal Behavior and Chemsex-A Narrative Review of the Literature

Chemsex is described as the use of certain drugs-commonly methamphetamine, gamma-butyrolactone (GBL)/gammahydroxybutyrate (GHB), and mephedrone-before or during planned sexual activity primarily among men who have sex with men (MSM). Evidence shows that MSM who engage in chemsex are at increased risk of physical harm, such as sexually transmittable infections (STIs), and are more likely to experience mental health symptoms. To further assess this, we reviewed the recent literature to evaluate whether the psychological impact of chemsex behavior includes suicidal ideation and suicidal attempts. Pubmed/MEDLINE was searched for articles reporting suicidal ideation and behavior among chemsex users with the terms "chemsex", "sexualized drug use", "suicide", and "mental health". Twelve articles (three case reports and nine cross-sectional studies) were included in the final narrative review. Overall, we retrieved mixed results regarding the relationship between chemsex practice and suicidality outcomes. Considering the inhomogeneous nature of the studies, the findings indicate that suicidality could be an issue of concern among MSM in general but among chemsex users in particular. Possible risk factors for suicidality among chemsex participants may include adversities experienced due to one's sexual orientation and an increased risk for HIV and other STI infections and the resulting negative impact on mental well-being. These aspects warrant further investigations.

Engagement in Chemsex among Men Who Have Sex with Men (MSM) in Malaysia: Prevalence and Associated Factors from an Online National Survey

Background: Chemsex is the use of illicit drugs—particularly methamphetamine, gamma hydroxybutyrate (GHB), and gamma-butyrolactone (GBL)—to enhance sexual activity. Chemsex, which occurs primarily among communities of men who have sex with men (MSM), is associated with greater HIV risk behaviors, including multiple sex partners, group sex, condomless sex, and injection drug use. Despite evidence showing chemsex engagement among Malaysian MSM, there is a paucity of research on chemsex among MSM in Malaysia. Methods: This cross-sectional study was conducted through an online survey (August to September 2021) among 870 Malaysian MSM. Participants were recruited through targeted advertisements on social networks. We collected information regarding participants’ recent (<6 months) engagement in chemsex, demographic characteristics, psychosocial factors, pre-exposure prophylaxis (PrEP) knowledge and history, and recent sexual- and drug-related behavior. Multivariable logistic regression was used to identify factors associated with recent (<6 months) chemsex engagement. Results: Just under 1 in 10 (9.0%) of participants reported having engaged in chemsex in the previous six months. More than two-thirds of participants (69.1%) had not disclosed their sexual orientation to anyone in their family and 35.2% reported moderate to severe depressive symptoms. Multivariable analysis found that recent injection drug use (adjusted odds ratio: aOR = 6.61; 95% confidence interval: CI, 2.30−19.03), having shared pre-exposure prophylaxis (PrEP) with someone else (aOR = 5.60; 95% CI, 1.76−17.77), higher perceived HIV risk (aOR = 3.15; 95% CI, 1.25−7.93), knowing someone using PrEP (aOR = 2.93; 95% CI, 1.62−5.31), recent engagement in transactional sex (aOR = 2.38; 95% CI, 1.06−5.39), having a recent STI diagnosis (aOR = 2.36; 95% CI, 1.25−4.44), recent engagement in anal sex (aOR = 2.21; 95% CI, 1.07−4.57), and recent sexual intercourse with an HIV-positive partner (aOR = 2.09; 95% CI, 1.07−4.08) were associated with recent engagement in chemsex. Conclusions: Malaysian MSM who practice chemsex are vulnerable to several HIV risk factors, such as transactional sex, HIV-positive sexual partners, and injection drug use. There is an urgent need for programs that integrate drug, sexual health, and mental health services, with a focus on harm reduction (e.g., condoms, access to and utilization of HIV testing and PrEP services, drug knowledge, and safer drug use) tailored for MSM who practice chemsex.

Using Intervention Mapping to Develop an mHealth Intervention to Support Men Who Have Sex With Men Engaging in Chemsex (Budd): Development and Usability Study

BACKGROUND

Chemsex refers to the intentional use of drugs before or during sex among men who have sex with men (MSM). Engaging in chemsex has been linked to significant negative impacts on physical, psychological, and social well-being. However, no evidence-based support tools have addressed either these harms or the care needs of MSM who engage in chemsex.

OBJECTIVE

The purpose of this paper was to describe the development of a mobile health intervention (named Budd) using the intervention mapping protocol (IMP). Budd aims to support and inform MSM who participate in chemsex, reduce the negative impacts associated with chemsex, and encourage more reasoned participation.

METHODS

The IMP consists of 6 steps to develop, implement, and evaluate evidence-based health interventions. A needs assessment was carried out between September 2, 2019, and March 31, 2020, by conducting a literature study and in-depth interviews. Change objectives were selected based on these findings, after which theory-based intervention methods were selected. The first version of the intervention was developed in December 2020 and pilot-tested between February 1, 2021, and April 30, 2021. Adjustments were made based on the findings from this study. A separate article will be dedicated to the effectiveness study, conducted between October 15, 2021, and February 24, 2022, and implementation of the intervention. The Budd app went live in April 2022.

RESULTS

Budd aims to address individual factors and support chemsex participants in applying harm reduction measures when taking drugs (drug information, drug combination tool, and notebook), preparing for participation in a chemsex session (articles on chemsex, preparation tool, and event-specific checklist), planning sufficient time after a chemsex session to recover (planning tool), seeking support for their chemsex participation (overview of existing local health care and peer support services, reflection, personal statistics, and user testimonials), taking HIV medication or pre-exposure prophylaxis in a timely manner during a chemsex session (preparation tool), and contacting emergency services in case of an emergency and giving first aid to others (emergency information and personal buddy).

CONCLUSIONS

The IMP proved to be a valuable tool in the planning and development of the Budd app. This study provides researchers and practitioners with valuable information that may help them to set up their own health interventions.

The World Federation of Societies of Biological Psychiatry guidelines on the assessment and pharmacological treatment of compulsive sexual behaviour disorder

OBJECTIVES

The current guidelines aim to evaluate the role of pharmacological agents in the treatment of patients with compulsive sexual behaviour disorder (CSBD). They are intended for use in clinical practice by clinicians who treat patients with CSBD.

METHODS

An extensive literature search was conducted using the English-language-literature indexed on PubMed and Google Scholar without time limit, supplemented by other sources, including published reviews.

RESULTS

Each treatment recommendation was evaluated with respect to the strength of evidence for its efficacy, safety, tolerability, and feasibility. Psychoeducation and psychotherapy are first-choice treatments and should always be conducted. The type of medication recommended depended mainly on the intensity of CSBD and comorbid sexual and psychiatric disorders. There are few randomised controlled trials. Although no medications carry formal indications for CSBD, selective-serotonin-reuptake-inhibitors and naltrexone currently constitute the most relevant pharmacological treatments for the treatment of CSBD. In cases of CSBD with comorbid paraphilic disorders, hormonal agents may be indicated, and one should refer to previously published guidelines on the treatment of adults with paraphilic disorders. Specific recommendations are also proposed in case of chemsex behaviour associated with CSBD.

CONCLUSIONS

An algorithm is proposed with different levels of treatment for different categories of patients with CSBD.

Methamphetamine use and adoption of preventive behaviors early in the COVID-19 pandemic among men who have sex with men in Los Angeles, California

Background

Methamphetamine (MA) use increased during COVID-19, with men who have sex with men (MSM) exhibiting 3-fold greater use than heterosexual men. Understanding links between reported MA use and COVID-19 prevention behaviors among MSM can inform current transmission risks for HIV, Monkeypox, and other infectious diseases.

Methods

This study assesses relationships between self-reported pattern of MA use (past six months; past two weeks) and reported COVID-19 preventive behaviors, adjusting for participant characteristics (HIV serostatus, race/ethnicity, employment and housing stability), in a cohort of ethnically diverse MSM in Los Angeles, California, between April 1 and September 30, 2020.

Results

Compared to those who reported no MA use, MSM who reported weekly or more MA use in the past six months were significantly less likely to use COVID-19 protective behaviors of physical distancing (61.8% vs. 81.6%; AOR = 0.39, 95% CI [0.19, 0.81]), of avoiding public transportation (34.5% vs. 60.3%; AOR = 0.42, 95% CI [0.21, 0.83]) and of avoiding traveling overall (32.7% vs. 62.6%; AOR = 0.32, 95% CI [0.16, 0.63]). Parallel findings were observed in analyses of past two-week reported MA use and COVID-19 protective behaviors.

Conclusion

Findings highlight ways in which reported MA use frequency links with avoidance of reported preventive behaviors for COVID-19 in urban diverse MSM. Findings also provide evidence to guide public health interventions in future outbreaks of COVID-19 and other infectious diseases among MSM.

Risk factors for HCV transmission in HIV-positive men who have sex with men in México

Purpose

In the last two decades transmission of hepatitis C virus (HCV) in HIV positive men who have sex with men (MSM) has been reported globally. Chemsex and specific sexual practices have been identified as risk factors. Our study aimed to identify risk factors for HCV transmission in MSM living with HIV attending in Mexico.

Methods

We conducted a case-control study from April to December 2019 at the Hospital de Infectología “La Raza” National Medical Center, in Mexico City. A case was defined as an HIV-infected MSM with positive HCV-antibody test. For each case, 3 controls were included, defined as HIV infected MSM with negative HCV-antibody test. A self-questionnaire covering sexual practices and other risk factors for HCV transmission was applied. Bivariate analysis was performed to obtain odds ratio (OR) using Chi-square test. Independent risk factors were identified in a subsequent analysis performing a logistic regression model.

Results

A total of 324 patients participated in the study, 81 cases and 243 controls. Median age was 30.5 years (IQR: 18–52) and 28.8 years (IQR: 21–45) in the case and control group, respectively. Most prevalent HCV genotype was 1a (79%). In the logistic regression model, sharing straw during cocaine inhalation (OR: 9.03; 95% CI; 1.35–13.52; P = 0.003), sharing sex toys (OR: 17.53, 95% CI; 6.85–44.86; P = 0.002), and ethyl chloride use for chemsex (OR: 2.26; 95% CI; 1.29–5.56; P = 0.037) were significant risk factors for HCV infection.

Conclusion

This study identifies risk factors for HCV transmission in Mexico in HIV positive MSM in congruence with the findings of many studies performed worldwide. This is the first study that indicates a possible association between ethyl chloride use in chemsex and HCV infection. Assessment of local populations for risk factors for HCV transmission may help to develop specifically targeted behavioral interventions to reduce HCV transmission.

Fatal Rectal Injection of 3-MMC in a Sexual Context. Toxicological Investigations Including Metabolites Identification Using LC-HRMS

The dead body of a 59-year-old man was found at his home by his father. The subject was naked in the corridor, wearing a black hood and a collar around the neck where a dog leash was attached. An empty syringe was discovered in the decedent's rectal vein. The autopsy revealed marked asphyxia signs with no indication of violence or trauma. Femoral blood, urine and hair (4 cm, brown) were collected and submitted for comprehensive toxicological investigation. Initial screening did not indicate the presence of ethanol or any other over-the-counter or prescription pharmaceuticals. Routine toxicology screening by liquid chromatography-tandem mass spectrometry (LC-MS-MS) tentatively identified only the cathinone stereoisomer(s), 3-methylmethcathinone (3-MMC) or mephedrone (4-MMC). Analysis by GC-MS to distinguish between the isomers revealed the presence of 3-MMC, which was subsequently quantified by LC-MS-MS. Femoral blood and urine concentrations were 1437 ng/mL and 16733 ng/mL, respectively. In 4 x 1 cm hair segments, 3-MMC was detected at less than 10 pg/mg (LOQ). Further analysis by high-resolution mass spectrometry (LC-HRMS) allowed identification of two metabolites in both blood and urine: desmethyl-3-MMC and hydroxyl-3-MMC. The pathologist established the cause of death in this case as acute 3-MMC poisoning in the context of ChemSex.

Self-Control as Conceptual Framework to Understand and Support People Who Use Drugs During Sex

Few theory-informed interventions to support people who use drugs during sex have been conceptualized and developed. We conceptualize sexualized drug use, also referred to as chemsex or pharmacosex, as a self-control challenge, and draw on extant theory and research to propose intervention approaches that can be tailored to meet the differing needs of people who engage in sexualized drug use. We draw on a continuum perspective of sexualized drug use, in particular chemsex, and discuss the role of reasoned and automatic processes in behavioral decisions, as well as critical components of effective self-control of behavior. A self-control approach can empower people to tackle their sexualized drug use, and classify their experienced sex-related drug use as problematic. Self-control encompasses clarifying one's goals and identifying strategies to mitigate behaviors to achieve these goals, despite competing pharmacosex desires. Our approach to self-control sexualized drug use contains three critical components: goal setting, goal enactment, and goal progress appraisal and goal adjustment. Goals should be formulated specific, ambitious yet realistic, and tailored to the individual's needs and wishes. Goals may target aspects of drug use, protecting sexual health and mitigating negative impacts. Implementing goal enactment implies translating goals into concrete (short-term) actions to move toward the higher-order goal via goal intentions and action/coping plans. During the goal progress appraisal and adjustment stage, people compare their actual with their planned behavior. This reflection may result in goal adjustment through feedback loops to adjust their goals and action/coping plans. We propose that our self-control approach can guide the development of interventions to effectively support people to prevent or limit pharmacosex, and helps to effectively mitigate or reduce negative impacts via self-help, peer support or professional support, offered via personal counseling or digital tools.

Methamphetamine Enhances Cryptococcus neoformans Melanization, Antifungal Resistance, and Pathogenesis in a Murine Model of Drug Administration and Systemic Infection

Methamphetamine (METH) is a major public health and safety problem in the United States. Chronic METH abuse is associated with a 2-fold-higher risk of HIV infection and, possibly, additional infections, particularly those that enter through the respiratory tract or skin. Cryptococcus neoformans is an encapsulated opportunistic yeast-like fungus that is a relatively frequent cause of meningoencephalitis in immunocompromised patients, especially in individuals with AIDS. C. neoformans melanizes during mammalian infection in a process that presumably uses host-supplied compounds such as catecholamines. l-3,4-Dihydroxyphenylalanine (l-Dopa) is a natural catecholamine that is frequently used to induce melanization in C. neoformans. l-Dopa-melanized cryptococci manifest resistance to radiation, phagocytosis, detergents, and heavy metals. Using a systemic mouse model of infection and in vitro assays to critically assess the impact of METH on C. neoformans melanization and pathogenesis, we demonstrated that METH-treated mice infected with melanized yeast cells showed increased fungal burdens in the blood and brain, exacerbating mortality. Interestingly, analyses of cultures of METH-exposed cryptococci supplemented with l-Dopa revealed that METH accelerates fungal melanization, an event of adaptation to external stimuli that can be advantageous to the fungus during pathogenesis. Our findings provide novel evidence of the impact of METH abuse on host homeostasis and increased permissiveness to opportunistic microorganisms.

PrEP Use and Correlates of Use Among a Large, Urban Sample of Men and Transgender Persons Who Have Sex with Men

We examined recent pre-exposure prophylaxis (PrEP) use (past 6 months) and its correlates among a large sample of men who have sex with men and transgender and gender non-conforming persons participating in a home HIV self-testing program conducted by the New York City Health Department between 11/2016 and 1/2017. Correlates examined included demographic characteristics and HIV-related behaviors in the past 6 months. Associations with recent PrEP use were assessed using log-binomial regression. 400 (22.5%) of 1776 participants reported recent PrEP use. In adjusted models, recent PrEP use was associated with Manhattan residence [adjusted prevalence ratio (aPR) 1.26; 95% confidence interval (CI) (1.04, 1.53)], higher income [aPR 1.29; 95% CI (1.03, 1.62)], and having insurance [aPR 1.89; 95% CI (1.33, 2.69)]. All HIV-related behaviors, except for injection drug use, were individually associated with PrEP use. More research is needed to better understand barriers to PrEP use among patients who are low income and/or uninsured as this may help improve current public health efforts to increase PrEP uptake among disproportionately impacted populations.

Risk Behaviors Associated with Patterns of Sexualized Stimulant and Alcohol Use among Men Who Have Sex with Men: a Latent Class Analysis

Substance use during sexual encounters (sexualized substance use) is an important driver of HIV and sexually transmitted infection (STI) disparities that are experienced by men who have sex with men (MSM). This analysis aimed to identify patterns of sexualized substance use and their associations with HIV risk behaviors. We utilized visit-level data from a longitudinal cohort of predominantly Black/Latinx MSM, half with HIV and half with substance use in Los Angeles, California. Every 6 months from 8/2014 to 3/2020, participants underwent STI testing and completed surveys on demographics, sexualized substance use (stimulant and/or alcohol intoxication during oral sex, receptive anal intercourse [RAI] and/or insertive anal intercourse [IAI]), transactional sex, biomedical HIV prevention (pre-/post-exposure prophylaxis use or undetectable viral load), and depressive symptoms. Latent class analysis was used to identify patterns of sexualized substance use. Multinomial logit models evaluated risk behaviors associated with latent classes. Among 2386 study visits from 540 participants, 5 classes were identified: no substance use, sexualized stimulant use, sexualized alcohol use, sexualized stimulant and alcohol use, and stimulant/alcohol use during oral sex and RAI. Compared to the no sexualized substance use class, sexualized stimulant use was associated with transactional sex, current diagnosis of STIs, not using HIV biomedical prevention, and depressive symptoms. Sexualized alcohol use had fewer associations with HIV risk behaviors. Patterns of sexual activities, and the substances that are used during those activities, confer different risk behavior profiles for HIV/STI transmission and demonstrate the potential utility of interventions that combine substance use treatment with HIV prevention.

Pre-exposure Prophylaxis Persistence Among Greek Sexual Minority Men: Results from PrEP for Greece (P4G) Study

Nearly half the new HIV infections in Greece occur in sexual minority men, yet pre-exposure prophylaxis is not currently supported in the national HIV program. We examined factors associated with PrEP persistence among Greek SMM in PrEP for Greece, the first PrEP study in Greece. Participants (n = 100) were recruited from 2016 to 2018 through respondent-driven sampling among SMM in Athens, receiving supplies for daily PrEP at interval visits over 12-months. PrEP persistence, operationalized as Total PrEP Time, was high, 74% of participants achieving perfect persistence. Higher alcohol risk scores (OR 1.27, 95% CI 1.08-1.49) and adherence to HIV testing guidelines (OR 1.23, 95% CI 1.00-1.51) were associated with persistence. Housing impermanence (OR 0.14, 95% CI 0.04-0.48) and serostatus disclosure concerns (OR 0.77, 95% CI 0.60-0.97) were associated with limited PrEP persistence. While PrEP persistence among Greek SMM is high, socioeconomic factors and societal attitudes may challenge prevention efforts.

Sexualized Drug Use and Chemsex: Their Association with Sexual Health Among Men who have Sex with Men Living in Greece

Objectives: The study aims to investigate rates of sexualized drug use (SDU) and chemsex, a type of SDU involving specifically the use of crystal methamphetamine, mephedrone, or GHB/GBL and their association with the rates of negative sexual health outcomes among men who have sex with men (MSM) in Greece. Methods: Survey of 485 MSM in internal disease departments and community testing centers. Results: Twenty-eight percent of participants were involved in SDU and 20.4% in chemsex. HIV positive status and recent STI diagnoses were associated with SDU involvement. Conclusion: SDU and chemsex rates and their impact on health reveal the need for informed community-based services.

Increasing emergency department admissions for chemsex-related intoxications in Barcelona, Spain, among people living with HIV: an observational study from 2018 to 2020

Background

Chemsex is a novel phenomenon referring to the use of drugs, including crystal methamphetamine, gammahydroxybutyric acid (GHB)/gamma-butyrolactone (GABA) and mephedrone, to facilitate, enhance, and prolong the sexual experience in men who have sex with men in large cities internationally. There is a growing concern about chemsex and fatal cases among people living with HIV on antiretroviral therapy. This study aimed to describe the clinical characteristics of chemsex-related intoxications.

Material and methods

An observational study was conducted in people living with HIV who were admitted for chemsex-related intoxications in an emergency department of a teaching hospital in Barcelona, Spain, from 2018 to 2020. Severe acute intoxications were defined according to the Poisoning Severity Score.

Results

One hundred and fifteen male patients with a median age of 35.6±7 years were included in the study:15 (13.1%) in 2018, 32 (27.8%) in 2019 and 68 (59.1%) in 2020. All patients had stable housing, 107(93.0%) were Spanish citizen and 32 (27.8%) had mental health disorders. Median CD4 lymphocyte count was 624 (500–765) cells/mm³ and 99 (86.1%) had HIV-1 RNA suppression.

Poly-drug use was observed in 51(44.3%) cases and methamphetamine in 75(65,2%) and gammahydroxibutiric acid in 68 (59.1%) were the main drugs used.

Potential drug interactions due to the inhibition of cytochrome P450 by antiviral therapy was determined in 36 (31.3%) patients. Severe intoxications cases affecting neurologic and respiratory systems were diagnosed in 12 (10.4%) patients and no patient died. CD4 cell counts ≤500 cells (O.R.:4.2; C.I.95%:1.2–14.6) and mental health disorders (O.R.: 2.9; C. I 95%: 0.8–9.9) were associated with severe acute drug intoxications in the bivariate analyses.

Conclusions

Chemsex-related intoxications are an increasing clinical problem in people living with HIV. Chemsex should be routinely screened and addressed in clinical practice, particularly for people with mental illness and low CD4 cell counts, who are at higher risk for severe intoxications.

High Rates of Sexualized Drug Use or Chemsex among Brazilian Transgender Women and Young Sexual and Gender Minorities

(1) Background: We aimed to estimate sexualized drug use (SDU) prevalence and its predictors among sexual and gender minorities. (2) Methods: We used an online and on-site survey to enroll sexual/gender minorities people between October-December/2020, and multivariate logistic regression to obtain SDU correlates. (3) Results: We enrolled 3924 individuals (280 transgender women [TGW], 3553 men who have sex with men [MSM], and 91 non-binary), 29.0% currently on pre-exposure prophylaxis (PrEP). SDU prevalence was 28.8% (95% confidence interval [CI] 27.4-30.2). TGW had 2.44-times increased odds (95%CI 1.75-3.39) of engaging in SDU compared to MSM, regardless of PrEP use. PrEP use (aOR 1.19, 95%CI 1.00-1.41), South/Southeast region (aOR 1.26, 95%CI 1.04-1.53), younger age (18-24 years: aOR 1.41, 95%CI 1.10-1.81; 25-35 years: aOR 1.24, 95%CI 1.04-1.53), white race/color (aOR 1.21, 95%CI 1.02-1.42), high income (aOR 1.32, 95%CI 1.05-1.67), binge drinking (aOR 2.66, 95%CI 2.25-3.14), >5 sexual partners (aOR 1.88, 95%CI 1.61-2.21), condomless anal sex (aOR 1.49, 95%CI 1.25-1.79), self-reported sexually transmitted infection (aOR 1.40, 95%CI 1.14-1.71), and higher perceived HIV-risk (aOR 1.37, 95%CI 1.14-1.64) were associated with SDU. (4) Conclusions: TGW had the highest SDU odds. SDU may impact HIV vulnerability among key populations and should be addressed in HIV prevention approaches.

Patterns and motivations of polysubstance use: a rapid review of the qualitative evidence

INTRODUCTION

Polysubstance use-the use of substances at the same time or close in time-is a common practice among people who use drugs. The recent rise in mortality and overdose associated with polysubstance use makes understanding current motivations underlying this pattern critical. The objective of this review was to synthesize current knowledge of the reasons for combining substances in a single defined episode of drug use.

METHODS

We conducted a rapid review of the literature to identify empirical studies describing patterns and/or motivations for polysubstance use. Included studies were published between 2010 and 2021 and identified using MEDLINE, Embase, PsycINFO and Google Scholar.

RESULTS

We included 13 qualitative or mixed-method studies in our analysis. Substances were combined sequentially to alleviate withdrawal symptoms or prolong a state of euphoria ("high"). Simultaneous use was motivated by an intention to counteract or balance the effect(s) of a substance with those of another, enhance a high or reduce overall use, and to mimic the effect of another unavailable or more expensive substance. Self-medication for a pre-existing condition was also the intention behind sequential or simultaneous use.

CONCLUSION

Polysubstance use is often motivated by a desire to improve the experience based on expected effects of combinations. A better understanding of the reasons underlying substance combination are needed to mitigate the impact of the current overdose crisis.

Sexual behaviors, cannabis, alcohol and monkeypox infection

The emergence of the monkeypox virus (MPXV) outbreak in 2022 is a worldwide health issue. The rapid increase of monkeypox cases caused the WHO to designate the escalating global monkeypox outbreak a Public Health Emergency of International Concern on July 23, 2022. The WHO has called on the group currently most affected by the virus, men who have sex with men (MSM), to limit their sexual partners. The diminution in number of sexual partners not only decreases the proportion of infected MSM but could also increases the number of days needed to reach a given infection level among the general population. Several behavioral factors could be associated with high levels of different sexual partners, such as cannabis use and alcohol consumption. Firstly, this review focuses on the association between cannabis and alcohol consumption and the number of sexual partners, and their possible impact on the current MPXV outbreak by impairing the immune responses. Secondly, this review investigated in the UK Biobank cohort the relationship between alcohol and cannabis use and the number of sexual partners. Among the 115,604 participants, 1.8% declared to be MSM, 1.9% to be WSW (women having sex with women), 43.3% men heterosexuals and 53.0% women heterosexuals. MSM and WSW showed higher lifetime sexual partners (N = 17.4 (SD:17.52) and N = 13.65 (SD: 13.21), respectively) compared to heterosexual men (N = 6.89 (SD: 9.47) and women (N = 5.19 (SD:6.56), p < 0.001. After adjustment for age, body mass index, lifetime sexual activity, educational and income levels, tobacco and cardiovascular diseases, cannabis use and alcohol consumption remained significantly associated with increase in the number of different sexual partners in all four subgroups. Thus, cannabis use and alcohol consumption may have two detrimental effects on the MPXV outbreak: by participating in the increase of the number of sexual partners which are mainly responsible for the augmentation of the number of new MPXV infected cases and by impairing the immune response to a viral infection. Health and safety policies should address the factors and practices, including chemsex, leading to an increase in risk of sexual behaviors responsible for MPXV dissemination in the worldwide population.

Toxicological Characterization of GHB as a Performance-Enhancing Drug

Performance-enhancing drugs (PEDs) are represented by several compounds used to ameliorate the image, the appearance, or an athletic or non-athletic performance. Gamma-hydroxybutyrate (GHB) is an endogenous molecule first used as anesthetic and then marketed as a nutritional supplement with a wide diffusion in the bodybuilding community. The aim of the present work is to provide a toxicological characterization of the use of GHB as a PED, including the scientific basis for its use, the patterns of use/abuse, and the health risks arising from its consumption in this peculiar recreative setting. A literature search was performed on multiple databases including experimental studies on humans and animals as well as epidemiological reports and forensic case reports/series. Experimental studies demonstrated that the use of GHB as a PED is motivated by the release of growth hormone and the induction of sleep. However, the panel of desired performance-related effects was much wider in real cases and epidemiological studies. Even though the use of GHB among bodybuilders has decreased, its use to enhance some kind of performance, particularly sexual ones or social-communicative ones, as well as means to increase mood and perceived energy, is still common.

Recreational Use of Oral PDE5 Inhibitors: The Other Side of Midnight

BACKGROUND

Nowadays, Oral phosphodiesterase type 5 inhibitors (PDE5Is) are widely used for the treatment of erectile dysfunction (ED). However, these drugs have become abused among some men for recreational use to enhance their sexual performance.

OBJECTIVE

To shed a light on the recreational use of oral PDE5Is.

METHODS

A literature review was performed in the PubMed, Medline Medical Subject Heading, Science Direct, Scopus, Cochrane Library, EMBASE, CINAHL, Academic Search Complete, Google scholar, Egyptian Knowledge Bank (EKB) databases, Medline, Embase, and Chem ID using the keywords; sexual health, erectile dysfunction, recreational use/abuse, phosphodiesterase type 5 inhibitors, sildenafil, tadalafil, vardenafil, avanafil, and adverse effects.

RESULTS

Overall, 52 studies were retained for review out of 166 papers. Twenty-two studies that assessed the prevalence of the problem were investigated including 25,279 men from different countries. Most of these studies were cross-sectional studies that depend on multiple questionnaires representing the extent as well as the attitude of the recreational use of PDE5Is.

CONCLUSION

Oral PDE5Is have become used among some men for recreational use to enhance their sexual performance. To counteract the possible side effects of such abuse, the media, as well as health authorities, should be aware of the potential adverse effects of such abuse and strengthen the regulatory activity to protect the customers from such risks.

Sex in Chemsex: Sexual Response, Motivations, and Sober Sex in a Group of Italian Men Who Have Sex With Men With Sexualized Drug Use

BACKGROUND

Most studies on chemsex focus on the health risks associated with the practice, whereas less attention has been paid to the perception of sexual gratification in men who have sex with men (MSM) who use these substances.

AIM

The purpose of this study was to explore the effects of chemsex substances on sexual response, motivations to engage in chemsex and the relationship with sober sex.

METHODS

Thirty-one Italian cisgender MSM involved in sexualized drug use were interviewed and transcripts were thematically analyzed.

OUTCOMES

An ad hoc grid exploring sociodemographic data, chemsex sexual experience, motives, and relationships with sober sex was used during telephone-based interviews.

RESULTS

Participants showed significant individual differences in how chems may affect their sexual experience. The most reported effects were an increase in sexual desire and subjective arousal, access to higher disinhibition, possible erection and ejaculation difficulties, significant extension of the sexual experience duration, and an intensified perception of intimacy and pleasure. All the positive outcomes of substances on sex creates a great curiosity around chemsex, which is among the primary motives to engage in chemsex for the first time. Over time, other motives may emerge, also connected to substance abuse and craving. Some men reported to be motivated by their partners and friends and to use chemsex to cope with depressive mood/anxiety symptoms, stress and sexual problems. Many differences were reported between chemsex and sober sex. Chemsex seems to embody the idea of transgressive and exciting sex, while sober sex is outlined as a more intimate encounter, that can be significantly affected by performance anxiety.

CLINICAL TRANSLATION

These results offer some new perspectives that may add interesting information to the literature and be fundamental for future prevention and harm-reduction projects.

STRENGTHS & LIMITATIONS

Although this study is based on a small group of Italian MSM and the interviews were not audio-recorded, transcripts were consistent with scientific literature that considers it important to pay attention to the positive links between sex and substance use.

CONCLUSION

The promotion of safer sexual behavior should contemplate an in-depth discussion and recognition of both pleasurable and distressing aspects of chemsex sexual experience, its motivations over time and perceived differences with sober sex.

Substance Use and Chemsex in MSM - A Latent Class Analysis

Engagement in “chemsex” among men who have sex with men is associated with higher rates of STIs and HIV seroconversion as well as an increased mental health burden. MSM were recruited for an anonymous online survey. The survey included questions of substance use, consumption motives, sexual risk behavior, HIV serostatus, and psychological characteristics. A latent class analysis was used to identify subgroups based on the consumed substances. 597 MSM answered the questionnaire. The latent class analysis revealed four different clusters. Most men described the use of amyl nitrite and cannabis ( n = 370). One cluster consumed mainly MDMA, cocaine, and amphetamine ( n = 106) and another cluster used mainly chemsex-related drugs ( n = 43). A fourth cluster reported a range of consumed substances ( n = 78). This cluster reported higher rates of suicide attempts, STIs, and risk behaviors. Substances typically related to chemsex were consumed in a sexualized context to a relevant extent.

Factors associated with chemsex in Portugal during the COVID-19 pandemic

Objective:

to investigate the factors associated with the practice of sex under the influence of drugs (chemsex) among Portuguese men who have sex with men during the period of social distancing to prevent the COVID-19.

Method:

online survey applied in May 2020 to a sample of 1,301 participants living in Portugal, recruited according to Respondent Driven Sampling and via social media Facebook^®. Descriptive and bivariate analyses were performed along with logistic regression to calculate adjusted Odds Ratio (ORa).

Results:

the prevalence of chemsex was 20.2%. The likelihood of practicing chemsex increased with group sex (ORa: 28.4, 95%CI 16.93–47.49); unprotected sex (ORa: 7.1 95%CI 4.57–10.99); the use of pre-exposure prophylaxis (PrEP) to prevent COVID-19 (ORa: 4.2, 95%CI 2.71–6.39) and COVID-19 testing (ORa: 1.9, 95%CI 1.15–3.10).

Conclusion:

the practice of chemsex among men who have sex with men during the COVID-19 pandemic in Portugal was very frequent and may support greater understanding of the role and impact of sexual behavior on the COVID-19 transmission rates and the current pandemic situation in Portugal.

Characteristics and Long Term Follow up of Men Who Suffer Ischemic Priapism Secondary to Recreational Use of Intracavernosal Injectable Medications

OBJECTIVE

To better understand patient experience, risk factors, culture, and ED outcomes surrounding recreational ICI use that led to ischemic priapism.

METHODS

After IRB approval, men presenting for ischemic priapism secondary to recreational ICI use from January 2010 to December 2018 were contacted by mail and then via telephone. Standardized questions were asked of all study participants on the topics of erectile function (IIEF-5), sexual practices, and at-risk behavior at the time of priapism. Qualitative data analysis was performed using grounded theory methodology.

RESULTS

14 men age 24-59 were successfully recruited. All men described themselves as men having sex with men (MSM) and one (7.1%) as having both male and female sexual partners. Average follow up IIEF-5 among participants was 13 (SD 4.0). Eleven men (78.6 %) described illicit drug use at the time of priapism. Qualitative data analysis yielded several preliminary themes: concomitant drug use, naivety, peer pressure, and delay in seeking treatment. Men frequently reported illicit drug use in group sex scenarios and ICI use under pressure to perform sexually or to counteract effects of illicit substances.

CONCLUSIONS

Recreational ICI in this cohort was part of a lifestyle of risky behavior. Methamphetamine use and group sex encounters strongly motivate recreational ICI use. Substance abuse centers may offer an entry point into this population for counseling and primary prevention.

Amyl Nitrite-Induced Hemolytic Anemia: Acute Therapy and Prevention

Inhaled nitrites have been a substance of recreational use for centuries, primarily among men who have sex with men (MSM). However, there is a lack of awareness of the use of inhaled nitrites in this population and the possible complications and health disparities it carries. In this case report, we present a 62-year-old man with a past medical history of glucose-6 phosphate dehydrogenase (G6PD) deficiency presenting with severe hemolytic anemia and methemoglobinemia after recreational use of inhaled nitrites. The case was complicated with the presence of methemoglobinemia in a patient with G6PD deficiency. This report also aims to increase awareness of the use of nitrites in the MSM population. The use of nitrites is a predictor for high-risk sexual behavior and is associated with positive human immunodeficiency virus (HIV) status.
