Qualitative analysis of cocaine and heroin users' main partner sex-risk behavior: is safety in love safety in health?

Systematic review of cognitive and behavioral strategies used in effective harm reduction interventions for people who use cocaine

OBJECTIVE

The aim of this systematic review is to identify cognitive and behavioral strategies that have been used in effective harm reduction interventions for people who use cocaine.

METHOD

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the search was performed on February 26, 2023 across databases including PsycInfo, PubMed, Scopus, and Web of Science. Studies were included if they (1) report the use of one cognitive or behavioral strategy, (2) have harm reduction as the objective, (3) involve participants who used cocaine as at least one of their substances, (4) be published within the last 10 years, and (5) have a randomized controlled trial design. The Cochrane RoB 2.0 Tool was used to assess risk of bias. The cognitive and behavioral strategies were extracted and organized based on their frequency of use in the studies and their corresponding outcomes.

RESULTS

The final synthesis included k = 10 studies with N = 3,567 participants. Psychoeducation strategies, influence on social norms, personalized feedback, increased self-efficacy and motivational interviewing were the most frequently used promising strategies across studies.

CONCLUSIONS

This review underscores the significance of incorporating cognitive and behavioral strategies within harm reduction interventions, as they represent a promising domain that could enhance the effectiveness of addressing cocaine use.

A qualitative study of service engagement and unmet needs among unstably housed people who inject drugs in Massachusetts

INTRODUCTION

People who inject drugs (PWID) are disproportionately affected by HIV in the United States, and HIV prevention and care services may be inaccessible to or underutilized by PWID. In 2018, the Massachusetts Department of Public Health (MDPH) and the Centers for Disease Control and Prevention (CDC) investigated an increase in HIV diagnoses primarily among unstably housed PWID in Lawrence and Lowell.

METHODS

The response team interviewed 34 PWID in Lawrence and Lowell, with and without HIV, to inform effective response strategies. Qualitative interviews were recorded, transcribed, and coded. Interviews were transcribed verbatim and coded using a thematic analysis approach structured around pre-designated research questions related to service engagement (including harm reduction services, substance use disorder treatment, medical services, shelters, and other community services), unmet needs, and knowledge gaps regarding HIV prevention.

RESULTS

Participants ranged in age from 20 to 54 years (median: 32); 21 of the 34 participants (62%) were male, and 21 were non-Hispanic white. Fifteen (44%) self-reported being HIV positive. All 34 participants had experienced homelessness in the past 12 months, and 29 (85%) had ever received services at syringe service programs (SSP). We identified five key themes: substance use as a barrier to accessing health and social services; experiences of trauma and mental illness as factors impacting substance use and utilization of services; unstable housing as a barrier to accessing services; negative perceptions of medication for opioid use disorder (MOUD); and the desire to be treated with dignity and respect by others.

CONCLUSIONS

Findings highlight the need for well-resourced and integrated or linked service provision for PWID, which includes mental health services, housing, MOUD, harm reduction, and infectious disease prevention and care services. Co-locating and integrating low-barrier services at trusted community locations, such as SSPs, could increase service engagement and improve health outcomes for PWID. Further implementation science research may aid the development of effective strategies for services for PWID and build trusting relationships between service providers and PWID.

Prevalence and associated factors of sexually transmitted infections among methamphetamine users in Eastern China: a cross-sectional study

BACKGROUND

The reported incidence of sexually transmitted infections (STIs) in China has been increasing over the last decades, especially among drug users, which has become one of the main burdens of public health in China. This study was conducted to estimate the prevalence and associated factors of STIs among non-injecting methamphetamine (MA) users in Eastern China.

METHODS

A cross-sectional survey was conducted among 632 MA users in Eastern China in 2017. Demographic characteristics, sexual behaviors, behaviors of MA use and sexual health knowledge were collected through questionnaire. First pass urine specimens were collected and detected for deoxyribonucleic acid (DNA) of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) with Nucleic Acid Amplification Technology (NAAT), while blood specimens were collected and detected for antibodies of Human immunodeficiency virus (HIV), Herpes simplex virus type-2 (HSV-2), and syphilis with enzyme-linked immune sorbent assay (ELISA).

RESULTS

Among the 632 MA users, 464 (73.42%) were males, 60.92% were < 35 years of age, 546 (86.39%) were Shandong residents. 317 (50.16%, 95% CI 46.26-54.06%) participants were tested positive for at least one kind of STIs, including 242 (38.29%, 95% CI 34.50-42.08%) for HSV-2, 107 (16.93%, 95% CI 14.01-19.85%) for active syphilis, 46 (7.28%, 95% CI 5.25-9.31%) for treated syphilis, 40 (6.33%, 95% CI 4.43-8.23%) for CT, 6 (0.95%, 95% CI 0.19-1.71%) for HIV, and 3 (0.47%, 95% CI 0.06-1.00%) for NG infection. 99 (15.66%, 95% CI 12.83-18.49%) participants were co-infected with two kinds of STIs, including 91 (14.40%, 95% CI 11.66-17.14%) participants were co-infected with HSV-2 and syphilis. 14 (2.22%, 95% CI 1.07-3.37%) participants were co-infected with three kinds of STIs, and 4 HIV positive participants were co-infected with both syphilis and HSV-2. In the multiple logistic regression analysis, the results showed that females (adjusted OR [AOR] = 7.30, 95% CI 4.34-12.30) and individuals ≥ 35 years of age (AOR = 2.97, 95% CI 2.04-4.32) were more likely to test positive for STIs among MA users, whereas participants who acquired sexual health knowledge primarily from the Internet (AOR = 0.57, 95% CI 0.40-0.82) and those whose regular partners did not use drugs (AOR = 0.59, 95% CI 0.37-0.94) were less likely.

CONCLUSIONS

This study found that the prevalence of HSV-2 and syphilis are alarming high among non-injecting MA users in Shandong Province in Eastern China. The prevention and control intervention of STIs among MA users in Shandong were needed, especially on females and MA users ≥ 35 years of age.

A qualitative study of injection and sexual risk behavior among unstably housed people who inject drugs in the context of an HIV outbreak in Northeast Massachusetts, 2018

BACKGROUND

To investigate the underlying causes of a sudden increase in HIV among people who inject drugs (PWID) and initiate an appropriate response to the outbreak, we engaged in in-depth qualitative interviews with members of the PWID community in Lawrence and Lowell, Massachusetts.

METHODS

We interviewed 34 PWID who were currently or recently unstably housed, then transcribed interviews and coded transcripts, grouping codes into categories from which we identified key themes.

RESULTS

Participants described a heightened threat of overdose prompting PWID to inject together, increasing opportunities for sharing injection equipment. There were misunderstandings about safe injection practices to prevent HIV transmission and a low threshold for injection-related risk taking. Stigma regarding HIV prevented conversations about HIV status. Less thought was given to sexual risks than injection-related risks for HIV transmission.

CONCLUSIONS

We found multiple facilitators of HIV transmission. Additional HIV education and prevention interventions focusing on both injection and sexual risk practices would benefit this population, in addition to structural interventions such as increased access and availability of syringe service programs.

An application of agent-based modeling to explore the impact of decreasing incarceration rates and increasing drug treatment access on sero-discordant partnerships among people who inject drugs

BACKGROUND

People who inject drugs (PWID) lag behind other key populations in HIV care continuum outcomes. The impacts of criminal justice reform and increasing drug treatment access on HIV have been underexplored.

METHODS

We developed agent-based models (ABM) of sexual partnerships among PWID and non-PWID, and injection equipment-sharing partnerships among PWID in five US cities (Baltimore, Boston, Miami, New York City, San Francisco) over 3 years. The first set of ABM projected changes in partnership discordance among PWID as a function of decreasing ZIP code-level incarceration rates. The second set projected discordance as a function of increasing ZIP code-level drug treatment access. ABM were parameterized and validated overall, and by city and PWID race/ethnicity (Black, Latino, White) using National HIV Behavioral Surveillance data, administrative ZIP code-level data, surveillance reports and prior literature. Informed by research on prisoner release and community-level HIV prevalence, reductions in incarceration rates were fixed at 5% and 30% and respectively projected to increase ZIP code-level HIV prevalence by 2% and 12%. Increases in drug treatment access were fixed at 30% and 58%.

RESULTS

In each city, a 30% reduction in ZIP code-level incarceration rates and 12% increase in ZIP code-level HIV prevalence significantly increased sero-discordance among at least one racial/ethnic group of PWID by 1-3 percentage points. A 5% reduction in incarceration rates, and 30% and 58% increases in drug treatment access, led to isolated significant changes in sero-discordance among Black and White PWID that were less than 1 percentage point.

CONCLUSION

Reductions in incarceration rates may lead to short-term increases in sero-discordant partnerships among some PWID by increasing community-level HIV prevalence. Efforts to increase HIV testing, engagement in care and community reintegration post release, should be strengthened in the wake of incarceration reform. Additional research should confirm these findings and explore the lack of widespread impacts of drug treatment in this study.

Sex Partner Type, Drug Use and Condom Use Self-Efficacy Among African Americans from Disadvantaged Neighborhoods: Are Associations with Consistent Condom Use Moderated by Gender?

Gender inequalities in sexual behavior are explored from the perspective of the theory of gender and power. This study focused on the effect of sex partner type (steady versus casual), drug use, and condom use self-efficacy regarding consistent condom use (CCU) among a community-based sample of adults. The sample included 1,357 African American men and women (M age 37.0, SD 13.1 years; 44% women, 66% men) from 61 disadvantaged census block groups in Atlanta, GA as part of a study of individual and neighborhood characteristics and HIV risk-taking. Having a steady partner decreased the odds of CCU, while higher condom use self-efficacy increased the odds of CCU. Among non-drug users, having a drug-using partner was associated with decreased odds of condom use for women only. Women with drug-using partners, especially a steady partner, were least likely to report CCU. Therefore, interventions intended to empower CCU among women need to expand beyond acknowledging the reduced control that women who use drugs demonstrate to also consider those who have drug-using sexual partners.

18O proteomics reveal increased human apolipoprotein CIII in Hispanic HIV-1+ women with HAART that use cocaine

PURPOSE

Drug abuse is a major risk factor in the development and progression of HIV-1. This study defines the alterations in the plasma proteome of HIV-1-infected women that use cocaine.

EXPERIMENTAL DESIGN

Plasma samples from 12 HIV-seropositive Hispanic women under antiretroviral therapy were selected for this study. Six sample pairs were matched between nondrug users and cocaine users. After IgG and albumin depletion, SDS-PAGE, and in-gel digestion, peptides from nondrug users and cocaine users were labeled with (16) O and (18) O, respectively, and subjected to LC-MS/MS and quantitation using Proteome Discover and QuiXoT softwares and validated by ELISA.

RESULTS

A total of 1015 proteins were identified at 1% false discovery rates (FDR). Statistical analyses revealed 13 proteins with significant changes between the two groups, cocaine and noncocaine users (p < 0.05). The great majority pertained to protection defense function and the rest pertained to transport, homeostatic, regulation, and binding of ligands. Apolipoprotein CIII was increased in plasma of HIV+ Hispanic women positive for cocaine compared to HIV+ nondrug users (p ≤ 0.05).

CONCLUSIONS AND CLINICAL RELEVANCE

Increased human apolipoprotein CIII warrants that these patients be carefully monitored to avoid the increased risk of cardiovascular events associated with HIV, HAART, and cocaine use.

Multi-dimensional factors associated with unprotected anal intercourse with regular partners among Chinese men who have sex with men in Hong Kong: a respondent-driven sampling survey

Background

The HIV prevalence and incidence among men who have sex with men (MSM) are high. Unprotected anal intercourse (UAI) with male regular partners (RP) is an important but under-emphasized risk behavior. The current study aimed to describe the prevalence of UAI with regular partner and the associated multi-dimensional factors with UAI among MSM in Hong Kong, China.

Methods

Respondent Driven Sampling method was used to recruit participants. A total of 285 participants were recruited, of whom 211 (75.1%) had had anal sex with RP in the last six months and their data were analyzed in this report. Weighed data were presented and logistic regression methods were fit.

Results

Participants’ high risk behaviors in the last six months included high prevalence of having had UAI with RP (45.8%), having had non-regular male sex partners (NRP: 27.3%) and UAI with such partners (18.9%). Adjusted for socio-demographic variables, factors associated with UAI with RP included: 1) substances use prior to having anal sex (65.7% versus 43.8%; AOR =2.36; 95% CI =1.07-5.18), 2) worry that condom use symbolizes mistrust (67.9% versus 44.3%; AOR = 2.91; 95% CI =1.19-7.10), 3) a lower perceived degree of the RP’s acceptance of condom use (91.7% versus 38.3%; AOR = 22.70; 95% CI =6.20-83.10), and 4) a higher level of impulsivity (61.1% versus 35.0%; AOR =4.02; 95% CI = 1.62-9.97). Two of these four variables, substances use (ORm = 2.28, 95% CI = 1.01-5.16) and perceived lower level of RP’s acceptance of condom use (ORm = 17.22; 95% CI = 5.06-58.62) were selected by the forward stepwise logistic regression model.

Conclusions

MSM with RP in Hong Kong is subjected to high risk of HIV transmission. Risk factors of UAI are multi-dimensional and interventions need to take into account factors of structural, interpersonal and individual levels.
