Changes in Reported Injection Behaviors Following the Public Health Response to an HIV Outbreak Among People Who Inject Drugs: Indiana, 2016.

A syringe services program (SSP) was established following the Indiana HIV outbreak among persons who inject drugs (PWID) in Scott County. Among Indiana-based PWID, we examined injection behaviors associated with HIV status, SSP use after its establishment, and changes in injection behaviors after the outbreak response. During 2016, we interviewed 200 PWID and assessed injection behaviors before the response by HIV status. We reported injection behaviors prior to the response and used Fisher's exact Chi square tests (P < 0.05) to assess differences by HIV status. Next, among persons who injected both before (July-December 2014) and after (past 30days) the response, we (1) reported the proportion of persons who used the SSP to obtain sterile syringes, and assessed differences in SSP use by HIV status using Fisher's exact Chi square tests; and (2) compared distributive and receptive sharing of injection equipment and disposal of syringes before and after the outbreak response, and assessed statistical differences using McNemar's test. We also compared injection behaviors before and after the response by HIV status. Injecting extended release oxymorphone (Opana® ER); receptive sharing of syringes and cookers; and distributive sharing of cookers, filters, or water before the response were associated with HIV infection. SSP use was high (86%), particularly among HIV-positive compared with HIV-negative persons (98% vs. 84%). Injection equipment sharing decreased and safe disposal of used syringes increased after the response, especially among HIV-positive persons. Injection equipment sharing contributed to the outbreak. High SSP use following the response, particularly among HIV-positive persons, contributed to decreased high-risk injection practices.

Hepatitis C prevalence among men who have sex with men in Central Brazil

To assess the prevalence of hepatitis C virus infection among men who have sex with men (MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti-HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/or those with elevated ALT were tested for HCV RNA and genotyped. Of the 522 participants, four were found to be anti-HCV positive, and one was also HCV RNA positive (active HCV infection). Elevated ALT was found in 14 individuals. Of these, one showed evidence of acute HCV infection (HCV RNA positive and anti-HCV negative). Therefore, five MSM were positive for either anti-HCV and/or HCV RNA, giving a crude overall HCV prevalence of 1.0%; 1.3% (95% CI: 0.3–5.5) after being weighted by RDSAT. All five individuals reported high-risk sexual behaviors, including two who showed evidence of active HCV infection (genotype 1, subtypes 1a and 1b). Although the study population reported high-risk sexual practices, HCV infection was not more frequent in MSM than in the general Brazilian population.

Penile implants and other high risk practices in French Guiana's correctional facility: A cause for concern.

BackgroundPrisoners in French Guiana, a French territory located in South America, have a HIV and hepatitis B prevalence of 4%. Body modifications such as penile implants, tattoos, and body piercings are common among detainees, increasing the risk of blood-borne virus transmission.MethodsWe conducted a cross-sectional randomised survey in which the primary objective was to estimate the prevalence of high risk ‘bloody practices’ (penile implants, tattoos, body piercings) in French Guiana’s only correctional facility. The secondary objective was to describe the risk factors for penile implants, the procedures and motivations for insertion, the reported complications, their risk factors and adverse impact on condom use.ResultsOf the 221 male inmates interviewed, 19% had tattoos or body piercings while incarcerated, and 68% had penile implants, of which, 85% had been inserted inside the correctional facility. Addictive behaviors such as cannabis use and alcohol addiction (positive AUDIT-C score), early age at first sexual intercourse, and the number of incarcerations correlated positively with having inserted one or more penile implants while incarcerated. In contrast, having reported previous psychiatric hospitalizations and having a high knowledge score for HIV/AIDS and sexually transmitted infections (STIs) were negatively correlated with the insertion of penile implants while incarcerated. Penile implants were inserted in poor hygienic conditions, usually using the sharp lid of a canned food container, with 18% of early complications, mostly haemorrhage and edema. Condom use was negatively impacted for 52% of men with penile implants.ConclusionsOur results highlight the need for prevention interventions which should aim at increasing knowledge levels and at implementing comprehensive risk-reduction measures.

Pathogens without borders

Purpose Drawing insights from the ecological theory, the purpose of this paper is to explore social determinants related to pathways to high-risk sexual behaviors of international travelers across their life span. Design/methodology/approach Data were collected from 45 international travelers in Houston, a critical transit point frequented by international visitors. Findings Overall, several ecological settings (individuals, interpersonal, institutional and contextual) related to two typologies of international travelers (risk takers vs non-risk takers) and their inclination to engage in high-risk sexual practices in an international or/and local context were identified. Research limitations/implications This research calls for the need to assess high-risk sexual behaviors from the ecological perspective to better understand the dynamics of disease transmission among frequent international travelers from diverse backgrounds/life styles and age cohorts. Practical implications Prevention and treatment programs developed for at-risk international travelers should target both distal and proximal social factors that predispose travelers to vulnerable situations. To build a reliable health surveillance network, policy makers, health practitioners and educators must focus not only on individual-level determinants but also on other ecological determinants that branch out beyond the personal level (e.g. interpersonal, institutional and contextual levels). Multi-level formal and informal social networks can be developed to promote a global social climate and environment that encourage safe sex and safety precautions. Social implications To raise awareness, the public must be constantly reminded that outbreaks of potentially health hazards can lead to unpredictable morbidity/mortality and security risks that place a burden on our nation’s economic growth, emergency responsiveness and homeland security infrastructure. Originality/value The study is one of very few to address international travelers’ health risk, while abroad, from an ecological lens across the life course.

Understanding the public health consequences of suspending a rural syringe services program: a qualitative study of the experiences of people who inject drugs

BackgroundSyringe services programs (SSPs) are evidence-based interventions that are associated with decreases in prevalence and incidence rates of HIV and viral hepatitis among people who inject drugs (PWID). SSPs are also effective conduits to deliver overdose prevention resources among PWID. In December 2015, the Kanawha-Charleston Health Department (KCHD) in West Virginia implemented a SSP; however, the program was indefinitely suspended in early 2018 following policy changes that would have forced the program to operate in ways that conflicted with established best practices. The purpose of this research is to explore the public health implications of the suspension of the KCHD SSP among rural PWID.MethodsWe conducted semi-structured interviews with 27 PWID (59.3% male, 88.9% White) to explore access to sterile injection equipment and overdose prevention resources, high-risk injection practices, and HIV risk perceptions following the KCHD SSP suspension. Participants were recruited from street locations frequented by PWID. Interviews were audio-recorded and transcribed verbatim. We employed an iterative, modified constant comparison approach to systematically code and synthesize textual interview data.ResultsParticipants described the KCHD SSP as providing a variety of harm reduction services to PWID and being able to speak honestly with SSP staff about their drug use without fear of stigmatization. The suspension of the KCHD SSP fundamentally changed the public health landscape for PWID, ushering in a new era of increased risks for acquiring bloodborne infections and overdose. PWID described more frequently injecting with used syringes and engaging in a range of high-risk injection practices after the SSP was suspended. PWID also discussed having decreased access to naloxone and being less likely to get routinely tested for HIV following the KCHD SSP suspension.ConclusionsThis research demonstrates that the suspension of a SSP in rural West Virginia increased risks for HIV/HCV acquisition and overdose among PWID. The suspension of the SSP led to community-wide decreases in access to sterile injection equipment and naloxone among PWID. The suspension of the KCHD SSP should be viewed as a call to action for sustaining evidence-based interventions in the face of sociopolitical forces that attempt to subvert public health.

Implementing pre-exposure prophylaxis could prevent most new HIV infections in transsexual women and men who have sex with men

BackgroundPre-exposure prophylaxis (PrEP) consists of administering antiretroviral drugs to HIV-seronegative individuals who engage in high-risk practices, with the aim of reducing the probability of acquiring the infection. Despite its safety and efficacy, PrEP is still not available within Spain's public healthcare system.The aim of this study was to estimate the preventive impact of adding PrEP to the other preventive measures. We estimated the number of HIV seroconversions that could have been prevented (if PrEP had been available) among initially seronegative transsexual women and men who have sex with men. MethodsWe conducted a descriptive study of recent HIV seroconverters between 2014 and 2016 in a reference HIV/sexually transmitted infection clinic in Madrid. We analyzed the individuals who were indicated PrEP, according to the guidelines of the 2016 AIDS Study Group. The statistical analysis to estimate the HIV infections that could have been prevented (if PrEP had been available) was conducted using Stata 14. ResultsWe estimated that 195 of the 228 men who have sex with men and transsexual women, with documented HIV seroconversion, were indicated for PrEP. Considering the preventive efficacy reported in European studies, we estimated that 168 HIV seroconversions could have been prevented, which represents 73.7% of the diagnosed infections. ConclusionsThe results confirm the need to promote combined preventive programs against HIV that integrate all possible measures, including PrEP.

La implementación de la profilaxis preexposición podría evitar la mayoría de las nuevas infecciones por el VIH en hombres que tienen sexo con hombres y mujeres transexuales

On the outside looking in: Finding a place for managed alcohol programs in the harm reduction movement

Alcohol policy in North America is dominated by moderation and abstinence-based modalities that focus on controlling population-level alcohol consumption and modifying individual consumption patterns to prevent and reduce alcohol-related harms. However, conventional alcohol policies and interventions do not adequately address harms associated with high-risk drinking among individuals experiencing severe alcohol use disorder (AUD) and structural vulnerability such as poverty and homelessness. In this commentary we address this gap in alcohol harm reduction, and highlight the lack of, and distinct need for, alcohol-specific harm reduction for people experiencing structural vulnerability and severe AUD. These individuals, doubly impacted by structural oppression and severe AUD, engage in various high-risk drinking practices that contribute to a unique set of harms that conventional abstinence-based treatments and interventions fail to adequately attend to. Managed alcohol programs (MAPs) have been established to address these multiple intersecting harms, and though gaining momentum across Canada, have had a hard time finding their place within the harm reduction movement. We illustrate how MAPs play a crucial role in the harm reduction movement in their ability to not only address high-risk drinking practices among structurally marginalized individuals, but to respond to harms associated with broader structural inequities such as poverty and homelessness.

ECOLOGY OF Staphylococcus aureus AND ITS ANTIBIOTIC RE-SISTANCE GENES IN DAIRY FARMS: CONTRIBUTING FACTORS AND PUBLIC HEALTH IMPLICATIONS

Dairy farms are major sources for zoonotic Staphylococcus aureus pathogens and their antibiotic resistance genes. This study was conducted to assess critical sources and factors related to dissemination of S. aureus and its resistance genes within dairy farms in Egypt. In addition, workers' knowledge, attitudes and practices (KAPs) was evaluated. A total of 102 pooled samples were collected from 3 medium-scale dairy farms in Egypt. S. aureus was detected in 72.5% of the examined samples: lactating cows (72.9%), workers (81.5%), barns environment (88.9%), milking equipment (40%), and bulk tank milk (100%). Cows (udder milk and nostril), workers (hand skin and nostril), barns, open-sides parlor, and lack of acid rinse were associated with S. aureus contamination of milking equipment (P= 0.004 - 0.04). Methicillin resistant S. aureus (MRSA, mecA+), vancomycin-resistant S. aureus (VRSA, vanA+) and methicillin-vancomycin-resistant S. aureus (MVRSA, mecA+-vanA+) represented 27.5%, 5% and 12.5% of S. aureus isolates, respectively. This is the first report of MVRSA in dairy farms in Egypt. For workers KAPs, 48.7% didn't know milk-borne zoonoses, while their high risk practices included consumption of raw milk (52.2%), lack of hand wash (48.7%), and willing to work with sore throat (82.6%). This study highlights the critical sources of S. aureus pathogens and their antibiotic resistance genes in dairy farms. This will help in reforming biosecurity plans in dairy farms; an urgent demand for consumers safety in Egypt.Key words: Staphylococcus aureus ecology; dairy farms; antibiotic resistance genes; public health implications

Reinfection by hepatitis C virus following effective all-oral direct-acting antiviral drug therapy in HIV/hepatitis C virus coinfected individuals.

We analysed hepatitis C virus (HCV) reinfection among participants in a prospective registry of HIV/HCV-coinfected patients treated with all-oral direct-acting antiretroviral (DAA)-based therapy in the region of Madrid. An observational cohort study. The study period started on the date sustained viral response (SVR) was confirmed. The censoring date was 31 December 2017. SVR was defined as negative HCV-RNA 12 weeks after completion of treatment. Reinfection was defined as a positive HCV-RNA test result after achievement of SVR. Reinfections were detected in 17 of 2359 HIV/HCV-coinfected patients (0.72%) overall, in 12 out of 177 (6.78%) MSM and in five out of 1459 (0.34%) people who inject drugs (PWID). The incidence of reinfection [95% confidence interval (95% CI)] per 100 person-years was 0.48 (0.30-0.77) overall, 5.93 (3.37-10.44) for MSM and 0.21 (0.09-0.52) for PWID. Reinfections were detected a median of 15 weeks (interquartile range 13-26) after SVR. In 10 (58.82%) patients, the reinfection was caused by a different HCV genotype. All 12 MSM with reinfection acknowledged unprotected anal intercourse with several partners, seven used chemsex, six reported fisting and four practiced slamming. A concomitant STI was detected in five patients. Four IDU with reinfection reported injecting drugs following SVR. HCV reinfection is a matter of concern in HIV-positive MSM treated with all-oral DAA therapy in the region of Madrid. Our data suggest that prevention strategies and frequent testing with HCV-RNA should be applied following SVR in MSM who engage in high-risk practices.

The Extended Fetal Cardiac Examination: Is It Feasible in a High-Risk Practice?

The aims of this study were to demonstrate the feasibility of obtaining additional cardiac views as proposed on an extended fetal cardiac examination and to see if there was any variation in individual components of that examination stratified by sonographer training, patient body habitus, or equipment. We retrospectively reviewed 200 consecutive detailed second-trimester high-risk fetal obstetric sonograms that included additional extended cardiac views. We analyzed the percentage of the time individual views were obtained, with variation based on (1) a sonographer with greater than 3 years of training compared with a group with 6 to 12 months of training, (2) 2 different ultrasound units, and (3) different body mass indices. Overall, the highest rate of visualization was achieved with the 4-chamber view (98.2%), whereas the 3-vessel tracheal view had the lowest percentage of visualization (40.2%), among the less experienced sonographers. Differences in successful completion of the extended cardiac views were not statistically different between the sonographer with a level of training greater than 3 years as compared with those with 6 to 12 months' training except for the 3-vessel tracheal view (P < 0.001). There is no statistically significant difference in our ultrasound equipment, when considering only inexperienced sonographers. Increasing body mass index had an inverse relationship with obtaining the components of the detailed cardiac examination. Using state-of-the-art ultrasound equipment and with focused additional training of obstetric sonographers, the majority of extended cardiac views can be obtained. There are exceptions.

Association of Self-Reported Abscess With High-Risk Injection-Related Behaviors Among Young Persons Who Inject Drugs.

Abscess is a common source of morbidity for people who inject drugs. We used data from the Study to Assess Hepatitis C Risk to measure prevalence of abscess and identify factors associated with the history of abscess. Of 541 participants, 388 (72%) were male and 149 (28%) were female. Almost half (n = 258, 48%) reported ever having an abscess. Persons who inject drugs with an abscess history were significantly more likely to have more injection partners (p = .01), inject heroin daily (p < .05), and share cookers (p = .001) and less likely to report using new syringes with each injection (p = .02). Most reported self-treating their last abscess and increasing drug use when having an abscess. High-risk injection-related activity was associated not only with infections such as HIV and hepatitis C virus but also with abscess. Nurses should screen patients presenting with abscess for high-risk practices and provide prevention education.

Brucellosis knowledge, attitudes and practices of a South African communal cattle keeper group.

Brucellosis remains an animal and public health concern in South Africa, given the intensity and widespread distribution of outbreaks in cattle. We conducted a cross-sectional survey among cattle keepers in the Whittlesea community of the Eastern Cape Province of South Africa, which utilises communal grazing. Individual cattle keepers (N = 227) who attended prearranged meetings in selected villages were interviewed using a structured questionnaire to assess their knowledge, attitude and practices (KAP) regarding bovine brucellosis. We compared KAP scores between previous brucellosis-affected villages and unaffected villages. We compared attitude and practices scores between those who had heard of brucellosis and those who had not and between those above the 75th percentile knowledge score and those below. The KAP for the study population were described using frequency tables. Scores of different groups were compared using the Welch t-test or the Wilcoxon rank-sum test. Knowledge scores of those who had heard of brucellosis (60%) showed a bimodal distribution with a 0/18 primary peak and 5–6/18 secondary peak. Attitude scores showed a median of 7/14 (interquartile range [IQR] 6–9), with 98% requesting more information on brucellosis. Practices scores showed a median of 6/18 (IQR 3–8), with high-risk practices identified that could facilitate brucellosis transmission. There were significant differences in attitude and practices scores between the groups above and below the 75th percentile knowledge score. The community showed poor knowledge, poor to average practices and average to good attitude. Identified high-risk practices highlight the risk of potential introduction and transmission of brucellosis between cattle and zoonotic transmission to humans.

Risk factors associated with horizontal transmission of hepatitis B viral infection from parents to children in Mexico.

Hepatitis B virus (HBV) infection in children is a health problem worldwide. In Mexico, a high prevalence rate of HBV infection and occult HBV infection have been reported in high-risk adults and children. However, studies regarding HBV infection transmitted from HBV-infected parents to children are limited. This study aimed to determine the risk factors associated with HBV transmission of HBV from parents to children in Mexico. A retrospective case-control study was carried out in 24 pediatric patients with clinical HBV infection and 48 healthy controls. Bivariate and forward conditional logistic regression analysis was used to compare demographic variables, the status of HBV vaccination, and risk factors for HBV infection transmission among children and their parents. No newborns were diagnosed with HBV infection, and no significant differences were found in age (p = 0.209) or gender (p = 0.612) compared to the control group. The independent risk factor associated with HBV transmission was the presence of a parent with a history of promiscuity (OR = 30.95, 95%CI = 3.382-283.326; p = 0.002), whereas having completed the HBV vaccination schedule for their age was a protective factor against HBV infection in the children (OR = 0.245, 95%CI = 0.079-0.764; p = 0.015). HBV infection in Mexican children is associated with close interpersonal contact with a parent engaged in high-risk sexual practices suggesting that the horizontal route could be the primary mode of infection. Child and adult vaccination campaigns should be reinforced to avoid HBV infection in Mexico.

Self-reported selected zoonotic diseases among animal handlers in Urban Ahmedabad, India.

Background and Aim:Out of all global microbial pathogens, 61% are zoonoses. Zoonotic diseases (Z/D/S) are responsible for a large burden on the public health, livestock economies, and wildlife of India. Data on burden and knowledge about Z/D/S among animal handlers are limited for urban and peri-urban areas of India. The present study aimed to estimate the prevalence of self-reported selected Z/D/S and knowledge about those diseases among animal handlers in the urban area of Ahmedabad city, India.Materials and Methods:This cross-sectional study was conducted among 170 animal handlers from three zones of Ahmedabad city, India, from February to May 2017. Data were collected on sociodemographic, different exposure, knowledge, practices about animal handling, and self-reported Z/D/S condition.Results:Majority of study participants were females. Participants had numbers of animals, and it ranged from 1 to 70. However, the majority of them were cattle. Average experience and hours/day spent for handling animal were reported 22±15 years and 5±2 h, respectively. From all participants, about one-third perceived that handling animal could be a cause of disease. Average knowledge on the mode of transmission of Z/D/S was found 4.1%. Most common high risk and preventive practices found consumption of raw milk (72%) and handwashing (83%). The proportion of self-reported Z/D/S in the past 5 years was found to be 23% among respondents and 17% among family members. However, the proportion of existing self-reported Z/D/S or symptomatic Z/D/S was 17% among respondents and 18% among family members. Most common self-reported Z/D/S were vector-borne, animal bite, and respiratory disorders.Conclusion:The knowledge and prevalence of Z/D/S were found low as compared to other studies from India. Further awareness and screening of animal handlers can be useful to increase the reporting and prevention and control of Z/D/S among them.

Persistent Opioid Use and High-Risk Prescribing in Body Contouring Patients.

Opioid misuse occurs commonly among obese patients and after bariatric surgery. However, the risk of new persistent use following postbariatric body contouring procedures remains unknown. The authors examined insurance claims from Clinformatics Data Mart (OptumInsight, Eden Prairie, Minn.) between 2001 and 2015 for opioid-naive patients undergoing five body contouring procedures: abdominoplasty/panniculectomy, breast reduction, mastopexy, brachioplasty, and thighplasty (n = 11,257). Their primary outcomes included both new persistent opioid use, defined as continued prescription fills between 90 and 180 days after surgery, and the prevalence of high-risk prescribing. They used multilevel logistic regression to assess the risk of new persistent use, adjusting for relevant covariates. In this cohort, 6.1 percent of previously opioid-naive patients developed new persistent use, and 12.9 percent were exposed to high-risk prescribing. New persistent use was higher in patients with high-risk prescribing (9.2 percent). New persistent use was highest after thighplasty (17.7 percent; 95 percent CI, 0.03 to 0.33). Increasing Charlson comorbidity indices (OR, 1.11; 95 percent CI, 1.05 to 1.17), mood disorders (OR, 1.27; 95 percent CI, 1.05 to 1.54), anxiety (OR, 1.41; 95 percent CI, 1.16 to 1.73), tobacco use (OR, 1.22; 95 percent CI, 1.00 to 1.49), neck pain (OR, 1.23; 95 percent CI, 1.04 to 1.46), arthritis (OR, 1.30; 95 percent CI, 1.08 to 1.58), and other pain disorders (OR, 1.36; 95 percent CI, 1.16 to 1.60) were independently associated with persistent use. Similar to other elective procedures, 6 percent of opioid-naive patients developed persistent use, and 12 percent were exposed to high-risk prescribing practices. Plastic surgeons should remain aware of risk factors and offer opioid alternatives. Risk, III.

High-risk psychotropic medications for US children with trauma sequelae.

Children exposed to trauma are predisposed to develop a number of mental health syndromes. They are prone to under-treatment with effective psychosocial interventions and over-treatment with high-risk psychotropic medications, especially polypharmacy and the use of antipsychotics for unapproved conditions. We review the evidence for psychosocial and pharmacological treatments for mental health problems associated with high exposure to childhood trauma - identifying those in foster care as an index group - and the frequency of high-risk pharmacological practices. We describe current efforts to reduce over-treatment of children with high-risk psychotropic medications and propose further recommendations to protect and provide effective care for these vulnerable children.

A latent class analysis of alcohol and drug use immediately before or during sex among women

ABSTRACT Background: Alcohol and drug use by women is related to high-risk sexual practices and protective behaviors. Objectives: To determine sexual risk and protective behaviors using information about women’s drug use immediately before or during sex. Methods: Latent class analysis using PROC LCA in SAS software was used to determine classes of women using both past 30-day drug use and before or during sex. Participants were recruited from a community-based research site located in a low socio-economic area of Los Angeles County and completed the Risk Behavior Assessment, which elicits information on drug and sex risk behaviors. Results: The Risk Behavior Assessment and HIV and sexually transmitted infections testing was obtained on 812 women. Five distinct groups were identified by PROC LCA: An Abstinent group comprised of 26% of participants; an Alcohol and Marijuana group (16%); an Amphetamine group (11%); a No Sex-with-Alcohol group (37%); and a Poly Drug group (11%). Multinomial logistic regression revealed that sexual behaviors and condom use were different across the five groups: The Alcohol and Marijuana group had a higher odds of vaginal intercourse, while the No Sex-with-Alcohol group was most likely to use condoms for vaginal intercourse. The Poly Drug group had the highest risk for anal intercourse while the Amphetamine and Poly Drug groups had high proportions of women with injection-drug using and men-who-have-sex-with-men sexual partners. Conclusion: Identifying women based on drug use immediately before or during sex can help providers understand prevention and risk-reduction practices and interventions for drug-using women.

Is on-Demand HIV Pre-exposure Prophylaxis a Suitable Tool for Men Who Have Sex With Men Who Practice Chemsex? Results From a Substudy of the ANRS-IPERGAY Trial.

Chemsex-the use of psychoactive substances during sexual encounters-among men who have sex with men is a growing concern. On-demand HIV pre-exposure prophylaxis (PrEP) may be a suitable tool to prevent HIV transmission among "chemsexers." We used the open-label extension study of the ANRS-IPERGAY trial to describe chemsexers and their PrEP use. Among the 361 men who have sex with men enrolled in ANRS-IPERGAY's open-label extension study, we selected the 331 with available data on drug use. A 2-monthly web questionnaire on sociobehavioral data was used to compare sexual behaviors between questionnaires where chemsex was reported and those where it was not. Using a generalized estimating equation logistic regression, we studied whether practicing chemsex was associated with correct PrEP use. Among the 331 participants, 30% reported chemsex practice at least once during follow-up and were considered chemsexers. Chemsex was reported in 16% of all questionnaires. Chemsexers were not significantly different from nonchemsexers regarding sociodemographic characteristics, although they reported greater use of anxiolytics and more sensation-seeking. Reporting chemsex was associated with more high-risk sexual practices and a higher perception of risk. After adjustment for other potential correlates, chemsex remained associated with correct PrEP use [odds ratio (95% confidence interval) = 2.24 (1.37 to 3.66)]. Our findings show that chemsexers were more likely to report high-risk sexual practices but also had a higher perception of risk. They were also more likely to use PrEP correctly when practicing chemsex. Consequently, PrEP may be a suitable tool to reduce HIV-risk transmission among chemsexers.

Human Papillomavirus Knowledge, Attitudes, Practices, and Prevalence Among Men Who Have Sex With Men in Monrovia, Liberia.

The aim of this study was to assess human papillomavirus (HPV) prevalence, knowledge, attitudes, and practices, among men who have sex with men (MSM) in Monrovia, Liberia. This cross-sectional study was conducted with 107 MSM, aged 18 to 58 years, completing questionnaires and anal HPV screenings. Using peer-educators and direct community involvement, demographics, risk factors, and HPV knowledge data were collected. Forty-eight participants (45%) were HPV positive and 21 participants (19.6%) self-identified as HIV positive. When examining HPV risk factors, 22 participants reported first sexual experience before the age of 15 years. Approximately half of participants (n = 58, 54.2%) have receptive anal sex and 40 (37.4%) reported more than 20 lifetime sexual partners. Eight participants (7.5%) had no formal education and 80 (74.8%) were not formally employed. Two-thirds of participants (64%) had never heard of HPV. Education was not significantly correlated with HPV knowledge. χ tests of independence were performed, and the relation between oral and anal sex and HPV knowledge was significant (χ (1) = 5.08, p < .05; χ (1) = 4.18, p < .05), respectively, such that those who engaged in oral and anal sex had lower levels of HPV knowledge. Among the MSM population, HPV prevalence is high, as are high-risk practices. Participants lack HPV knowledge, independent of educational achievement, and are eager to receive educational information. Future studies should focus on identifying additional risk factors and implementing public health educational interventions.
