Abstract
ABSTRACT In the U.S. South, over half of new HIV diagnoses occur among Black Americans with research lagging for women who face increased HIV rates and low PrEP uptake, among other health inequities. Community engaged research is a promising method for reversing these trends with established best practices for building infrastructure, implementing research, and translating evidence-based interventions into clinical and community settings. Using the 5Ws of Racial Equity in Research Framework (5Ws) as a racial equity lens, the following paper models a review of a salon-based intervention to improve PrEP awareness and uptake among Black women that was co-developed with beauty salons, stylists, and Black women through an established community advisory council. In this paper we demonstrate how the 5Ws framework was applied to review processes, practices, and outcomes from a community-engaged research approach. The benefits of and challenges to successful collaboration are discussed with insights for future research and community impact.

Jaffe K, Richardson L. "I thought it was for guys that did needles": Medication perceptions and lay expertise among medical research participants. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 154:209134.

Abstract
INTRODUCTION Although randomized controlled trials (RCTs) examine "objective" indicators of safety and efficacy of investigational drugs, participants may not perceive study medications as neutral entities. Some medications are imbued with social and cultural meaning, such as stigmatized medications for opioid use disorders. Such perceptions surrounding substance use treatments can extend to the research context and shape RCT participants' experiences with and adherence to study medications. METHODS Considering these complexities in substance use research, we conducted a nested qualitative study within a multi-site, pragmatic RCT in Canada testing two treatments (methadone versus buprenorphine/naloxone) for opioid use disorder. Between 2017 and 2020, we conducted 115 interviews with 75 RCT participants across five trial sites in British Columbia, Alberta, Ontario, and Quebec. RESULTS Using an abductive coding approach, we characterized participants by their previous experience with medication for opioid use disorder and by their exposure to drug culture and drug scenes. Across these experience types, we identified systematic differences around participants' perceptions of the study medications, sources of information and expertise, and medication stigma. CONCLUSION Our findings illustrate the critical importance of social context in shaping medication beliefs and study experiences among people who use drugs, with implications for the conduct of future RCTs in substance use.

Abstract
The objectives of this study were to 1) identify vaccination rates among PWID in Oregon at a time when vaccines were easily accessible, 2) quantitatively identify convergence with demographic correlates of vaccination willingness and uptake to promote generalizability, and 3) explore the factors PWID were considering when deciding whether or not to receive the COVID-19 vaccine. We conducted a mixed-methods study design including 260 quantitative surveys and 41 in-depth qualitative interviews with PWID, conducted July - September 2021 at syringe services programs in Lane County, Oregon. Among the 260 survey respondents, 37.3% indicated that they had received a COVID-19 vaccine by October 1, 2021. In the same period, an estimated 70.1% of the total Lane County population had completed their COVID-19 vaccinations (not including booster rounds). We explored alignment with the WHO's 3C model of vaccine hesitancy and identified, instead, five common factors as key motivators for vaccine decisions: confidence, convenience, concern, communication, and community implications among PWID. Interviews with PWID describe systemic barriers which prevented them from accessing healthcare resources. We highlight that our proposed 5C model may more accurately depict how PWID navigate vaccine decisions by incorporating the ways that social inequities, infrastructural barriers, and community values influence an individual's vaccine deliberation.

Abstract
BACKGROUND Since 2019, multiple HIV outbreaks occurred among people who inject drugs (PWID) in Minnesota. Syringe service programs (SSPs) are evidence-based programs that reduce the spread of HIV. We conducted an assessment of characteristics and HIV risk and prevention among clients of a delivery-based SSP near an HIV outbreak in rural, northern Minnesota. METHODS In the fall of 2021, we conducted a cross-sectional survey of clients of a mobile SSP based in Duluth, Minnesota. Survey topics included demographics, drug use, sexual behavior, HIV testing history, and HIV status. We conducted descriptive analyses and used univariate logistic regression to identify correlates of syringe sharing. The analysis was limited to PWID in the last six months. RESULTS A total of 125 people were surveyed; 77 (62%) were PWID in the last six months. Among these participants, 52% were female and 50% were homeless. Thirty-two percent reported sharing syringes and 45% reported sharing injecting equipment. Approximately one-half (49%) of participants had been tested for HIV in the past year, and none reported being HIV-positive. Individuals reported low condom usage (88% never used), and 23% of participants reported engaging in some form of transactional sex in the last six months. Incarceration in the last year was associated with sharing syringes (odds ratio = 1.4, 95% confidence interval 1.1-1.8). CONCLUSION HIV risk was high among PWID receiving services at this SSP. These data highlight a rural SSP that is engaged with people at risk for HIV and needs additional support to expand harm reduction services.

Abstract
Antiretroviral therapy has been effective in suppressing HIV viral load and enabling people living with HIV to experience longer, more conventional lives. However, as people living with HIV are living longer, they are developing aging-related diseases prematurely and are more susceptible to comorbidities that have been linked to chronic inflammation. Coincident with HIV infection and aging, drug abuse has also been independently associated with gut dysbiosis, microbial translocation, and inflammation. Here, we hypothesized that injection drug use would exacerbate HIV-induced immune activation and inflammation, thereby intensifying immune dysfunction. We recruited 50 individuals not using injection drugs (36/50 HIV+) and 47 people who inject drugs (PWID, 12/47 HIV+). All but 3 of the HIV+ subjects were on antiretroviral therapy. Plasma immune profiles were characterized by immunoproteomics, and cellular immunophenotypes were assessed using mass cytometry. The immune profiles of HIV+/PWID-, HIV-/PWID+, and HIV+/PWID+ were each significantly different from controls; however, few differences between these groups were detected, and only 3 inflammatory mediators and 2 immune cell populations demonstrated a combinatorial effect of injection drug use and HIV infection. In conclusion, a comprehensive analysis of inflammatory mediators and cell immunophenotypes revealed remarkably similar patterns of immune dysfunction in HIV-infected individuals and in people who inject drugs with and without HIV-1 infection.

Abstract
Analytic treatment interruption (ATI) is scientifically necessary in HIV-remission ("cure") studies to test the effects of new interventions. However, stopping antiretroviral treatment poses risks to research participants and their sexual partners. Ethical debate about whether and how to conduct such studies has largely centered on designing risk-mitigation strategies and identifying the responsibilities of research stakeholders. In this paper, we argue that because the possibility of HIV transmission from research participants to partners during ATI cannot practicably be eliminated-that is, it is ineliminable-the successful conduct of such trials ultimately depends on relationships of trust and trustworthiness. We describe our experiences with conducting and studying HIV-remission trials with ATI in Thailand to examine the strengths, complexities, and limitations of the risk-mitigation and responsibility approaches and to explore ways in which the building of trust-and trustworthiness-may help enhance the scientific, practical, and ethical dimensions of these trials.

Abstract
The Botshelo Ba Trans study was the first HIV bio-behavioral survey conducted with transgender women in South Africa. Engaging research with marginalized communities requires clear points of entry, reference points for understanding the internal culture, and establishing trust and understanding. The community-based participatory research approach guided the development and implementation of this study. We conducted a rapid qualitative and pre-surveillance formative assessment between August 2017 to January 2018 and a bio-behavioral survey between July 2018 and March 2019. At the start, a Steering Committee, comprising primarily of transgender women, was established and subsequently provided substantial input into the mixed methods study conducted in Buffalo City, Cape Town, and Johannesburg. Key to the study's success was building trust and establishing ownership of the survey by transgender women recognized as expert knowledge holders. Thus, a community-based participatory research-informed approach enhanced the validity of the data and ensured that we addressed relevant issues.

Abstract
Background People who inject drugs (PWID) are disproportionately affected by HIV despite the availability of multiple efficacious biomedical prevention interventions including oral pre-exposure prophylaxis (PrEP). Little is known about the knowledge, acceptability, and uptake of oral PrEP among this population in Kenya. To inform the development of oral PrEP uptake optimization interventions for PWID in Kenya, we conducted a qualitative assessment to establish oral PrEP awareness and willingness to take PrEP by this group in Nairobi City. Methodology Guided by the Capability, Opportunity, Motivation, and Behaviour (COM-B) model of health behavior change, we conducted 8 focus group discussions (FGDs) among randomly constituted samples of PWID in four harm reduction drop-in centers (DICs) in Nairobi in January 2022. The domains explored were: perceived risks (behaviour), oral PrEP awareness and knowledge (capability), motivation to use oral PrEP (behaviour), and perceptions on community uptake (motivation and opportunity). Completed FGD transcripts were uploaded to Atlas.ti version 9 and thematic analysis was conducted through an iterative process of review and discussion by two coders. Findings There was a low level of oral PrEP awareness with only 4 of the 46 PWID having heard of PrEP; only 3 out of 46 participants had ever used oral PrEP and 2 out of 3 were no longer using it, indicating a low capacity to make decisions on oral PrEP. Most study participants were aware of the risk posed by unsafe drug injection and expressed willingness to take oral PrEP. Nearly all participants demonstrated low understanding of the role oral PrEP plays in complementing condoms in HIV prevention, presenting an opportunity for awareness creation. While the PWID were eager to learn more about oral PrEP, they favored DICs as places where they would like to obtain information and oral PrEP if they chose to use it, identifying an opportunity for oral PrEP programming interventions. Conclusion Creation of oral PrEP awareness among PWID in Kenya is likely to improve uptake since the PWID are receptive. Oral PrEP should be offered as part of combination prevention approaches, and effective messaging through DICs, integrated outreaches, and social networks are recommended to mitigate displacement of other prevention and harm reduction practices by this population.

Abstract
Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are often co-transmitted. Viral coinfection results in worse outcomes. Persons who inject drugs (PWIDs) face barriers to medical treatment, but HCV treatment is indicated and effective even with ongoing active drug use. We aimed to assess access to HCV care and treatment results in patients coinfected with HIV-HCV. This is a real-world retrospective single-center study of patients followed in the HIV clinic between 2002 and 2018. Linkage to care was defined as achieving care cascade steps: (1) hepatology clinic visit, (2) receiving prescription of anti-HCV treatment, and (3) documentation of sustained virologic response (SVR). Of 1660 patients with HIV, 254 with HIV-HCV coinfection were included. Only 39% of them achieved SVR. The rate limiting step was the engagement into hepatology care. Being a PWID was associated with ~50% reduced odds of achieving study outcomes, active drug use was associated with ~90% reduced odds. Older age was found to facilitate treatment success. Once treated, the rate of SVR was high in all populations. HCV is undertreated in coinfected young PWIDs. Further efforts should be directed to improve access to care in this marginalized population.

Abstract
The hepatitis C virus (HCV) infection is an important public health problem, affecting millions of people worldwide. People who inject drugs (PWID) are at increased risk of HCV infection due to, among other factors, widespread unsafe injecting practices, such as sharing of infected equipment or unprotected sexual practices. In Portugal, there is a lack of data regarding the proportion of infected persons through injecting drug use. This study aimed to evaluate the anti-HCV prevalence and behavioral correlates of infection in PWID attending harm reduction services in the Metropolitan Area of Lisbon, Portugal. A cross-sectional study with a purposive sample of PWID was undertaken between March 2018 and March 2020. Participants were recruited through the harm-reduction services of a nongovernmental organization. A rapid diagnostic test for anti-HCV screening was performed. Data on drug consumption history and current practices, past HCV testing, care and treatment history, and knowledge regarding hepatitis C were also collected through a questionnaire applied by trained inquirers. A total of 176 PWID participated in this study. An overall prevalence of 70.5% of anti-HCV positive in this population was found. Those with an anti-HCV positive testing result tended to start consuming at a younger age and have a higher consumption of benzodiazepines in the last 30 days. Sharing needles and other injecting material is a frequent risk behavior among this group. Also, they are more likely to have attended an opioid agonist treatment and to have undertaken previous hepatitis C and HIV tests in the past. This study represents an important effort to better understand the HCV prevalence and behavioral correlates of infection among PWID in Portugal, as well as to better estimate those in need of HCV treatment.

Abstract
Background: Hepatitis C virus (HCV) infection is a primary health concern among people
who use drugs (PWUDs). Homeless PWUDs that constitute a key population for
HCV transmission remain underrepresented in many surveys. Objectives: We performed a proactive street outreach to evaluate HCV infection prevalence
among homeless PWUDs in Tel Aviv, identify risk factors associated with HCV
infection, awareness of disease status and linkage to care rate. Results: Thirty-eight percent of approached PWUD were willing to participate in the
study. Out of 53 subjects who got tested for anti HCV by rapid test, 29
(54.72%) had a positive result, 20 of 29 anti-HCV positive (69%) patients
had positive HCV PCR. Risk factors were investigated using structured
questionnaires. Heroin use was reported significantly more frequently in the
HCV-positive group (P = .05, CI 95%),
whereas other established risk factors did not reach significance in our
cohort. While 21 of 29 (72%) HCV-positive participants were aware of their
condition, only 4 of 21 (19%) received treatment in the past, and 2 of 4
(50%) failed to achieve treatment goals, as assessed by HCV PCR. Conclusions: Our data indicate a high prevalence of HCV infection among homeless PWUDs.
Importantly, despite relatively high awareness of HCV status in this
population, we found strikingly low access to care. These findings motivate
novel interventional approaches targeted at improving patient access, and
compliance among homeless PWUDs, in an effort to reduce HCV
transmission.

Abstract
Human immunodeficiency virus (HIV) continues to disproportionately affect gay, bisexual, and other men who have sex with men (GBM) and transgender and nonbinary (trans/NB) individuals. This study investigated attitudes toward participation in HIV survey research, guided by Emanuel's framework for ethical clinical research (e.g., risk-benefit ratio, fair participant selection, respect for participants, social value, and collaborative partnership). GBM (n = 294) and trans/NB (n = 86) persons recruited at a Pride event in Milwaukee completed a survey assessing risks and benefits of participation in, and comfort responding to, sexual health surveys. Participants reported few ethical concerns (e.g., privacy and confidentiality), with notable differences by race, sexual orientation and gender identity, and prior research experiences. Implications for HIV research with GBM and trans/NB individuals are discussed.

Abstract
INTRODUCTION Leveraging interpersonal communication among social networks of people who inject drugs (PWID) may be an innovative strategy to increase awareness and access to hepatitis C (HCV) care. However, little is known about HCV communication patterns among PWID and if these patterns vary by gender. METHODS Egocentric network data collected at baseline from HCV-infected PWID enrolled in a randomized HCV treatment intervention trial in Baltimore, Maryland were analyzed. Logistic generalized estimating models were conducted to identify predictors of HCV communication. RESULTS Among 227 PWID, the mean age was 43.8 (SD=10.3), 28.2% (n = 64) were women and 71.8% (n = 163) were men. Female participants reported 516 dyadic relationships and male participants 1139 dyadic relationships. While there were significant gender differences based on socio-demographics, risk behavior and network composition, there were few differences in HCV communication patterns. Both men and women had increased odds of HCV communication with alters who are currently enrolled in drug treatment (AOR 1.7, 95% CI: 1.3-2.4), alters with whom participants share drug preparation equipment (AOR 3.0, 95% CI: 1.9-4.6), alters who are sex partners compared to kin (AOR 3.0; 95% CI: 1.9-4.9) and alters with whom respondents have increased trust (AOR 1.1; 95% CI: 1.11.2) and daily/weekly interactions (AOR 1.7; 95% CI 1.3-2.1). CONCLUSION PWID engaged with trusted alters about HCV disclosure and information, highlighting the important role network interventions could play in this vulnerable population.

Abstract
Scale-up of pre-exposure prophylaxis (PrEP) in people who inject drugs (PWID) remains suboptimal. Patient-level factors are often complex and may contribute to scale-up. Using cross-sectional data from 234 opioid-dependent patients on methadone who met eligibility criteria for PrEP, we conducted logistic regression analyses to assess potential moderators associated with being on PrEP (n = 60). Mean provider trust was significantly higher among Blacks vs Whites (39.4 vs 34.9; p = 0.002) and non-homeless vs homeless participants (37.5 vs 34.8; p = 0.008). Though race/ethnicity was not a significant moderator on provider trust and PrEP use, increased provider trust was marginally associated with increased PrEP use among Blacks (p = 0.058). Additionally, homelessness significantly moderated provider trust and PrEP use (p = 0.024). Provider trust among non-homeless participants was positively correlated with PrEP use (p = 0.013) but not among homeless participants. Strategies that promote provider trust in Blacks and non-homeless PWID on methadone may improve PrEP scale-up.

Abstract
(1) Background: People who inject drugs (PWID) and needle and syringe program (NSP) providers increasingly partner with researchers to explore harm reduction best practice. However, a paucity of research exists regarding how best to engage PWID and community NSP providers to generate the evidence for sustainable harm reduction services. (2) Aim: This study reports on our use of an organic community research partnership-building approach between researchers, NSP providers, and PWID in Canberra ACT, Australia. (3) Method: Survey participants included both PWID (n = 70) and NSP providers (n = 26) across primary (n = 2), secondary (n = 7), and outreach (n = 1) services in Canberra ACT. Applying an organic partnership-building strategy, we engaged with partners and adapted approaches according to information gained in the process of implementation. (4) Results: We found engaging in relationship building around partner priority activities created mutual understanding and trust premised in authenticity of the evolving partnership. Our organic approach, which included a partner audit of the research tools for relevance, resulted in high acceptance and enrolment into the research by NSP providers and PWID. Finally, we observed strong social capital building utilizing an organic approach for the sustainability of the partnership. (5) Conclusions: The results of this study provide evidence for the benefits of organic collaborative research partnership building with NSP providers and PWID for authentic service program implementation. Our approach to research partnership building resulted in strong relationships built on shared goals and objectives, mutual gains, and complementary expertise. We propose the wider use of organic approaches to developing collaborative research partnerships with NSP providers and PWID to enhance consumer responsiveness towards service provision.

Abstract
BACKGROUND Georgia has a significant risk of ongoing HIV and HCV outbreak. Within this context, harm reduction aims to reduce risk associated with drug use through community activities, such as peer recruitment and involvement. The aim of this study was to identify significant differences between known and hidden populations, and attest to the ongoing utility of peer-driven intervention across multiple years in recruiting high-risk, vulnerable populations through peer networks. It was hypothesised that significant differences would remain between known, and previously unknown, members of the drug-using community, and that peer-driven intervention would recruit individuals with high-risk, vulnerable individuals with significant differences to the known population. METHODS Sampling occurred across 9 months in 11 cities in Georgia, recruiting a total of 2807 drug-using individuals. Standardised questionnaires were completed for all consenting and eligible participants, noting degree of involvement in harm reduction activities. These data underwent analysis to identify statistically significant different between those known and unknown to harm reduction activities, including in demographics, knowledge and risk behaviours. RESULTS Peer recruitment was able to attract a significantly different cohort compared to those already known to harm reduction services. Peer-driven intervention was able to recruit a younger population by design, with 25.1% of PDI participants being under 25, compared to 3.2% of NSP participants. PDI successfully recruited women by design, with 6.9% of PDI participants being women compared to 2.0% in the NSP sample. Important differences in drug use, behaviour and risk were seen between the two groups, with the peer-recruited cohort undertaking higher-risk injecting behaviours. A mixture of risk differences was seen across different subgroups and between the known and unknown population. Overall risk, driven by sex risk, was consistently higher in younger people (0.59 vs 0.57, p = 0.00). Recent overdose was associated with higher risk in all risk categories. Regression showed age and location as important variables in overall risk. Peer-recruited individuals reported much lower rates of previous HIV testing (34.2% vs 99.5%, p = 0.00). HIV knowledge and status were not significantly different. CONCLUSIONS Significant differences were seen between the known and unknown drug-using populations, and between previous and current research, speaking to the dynamic change of the drug-using culture. The recruitment strategy was successful in recruiting females and younger people. This is especially important, given that this sampling followed subsequent rounds of peer-driven intervention, implying the ability of peer-assisted recruitment to consistently reach hidden, unknown populations of the drug-using community, who have different risks and behaviours. Risk differences were seen compared to previous samples, lending strength to the peer-recruitment model, but also informing how harm reduction programmes should cater services, such as education, to different cohorts.

Abstract
In randomised controlled trials (RCTs), 'therapeutic optimism' describes a participant's belief they will benefit from the study treatment, despite the express goal of RCTs to test unknown aspects of interventions. Harbouring such expectations may interfere with RCT participation experiences, particularly among marginalised populations, such as people with substance use disorders (PSUD) who may experience social and structural barriers to participation that also increase their vulnerability to therapeutic optimism. However, little research explores therapeutic optimism within substance use trials. Thus, we conducted a nested qualitative study within an RCT testing a treatment for alcohol and opioid use disorders in HIV clinics. Using interviews with 22 participants in Vancouver, Canada, analysis revealed themes relevant to therapeutic optimism, that were specifically linked to intrinsic (e.g. health-related) or extrinsic motivations (e.g. stipend). First, compared to extrinsically motivated participants, intrinsically motivated participants held high expectations for the trial and attributed greater agency to the study medication. Second, intrinsically motivated participants expressing therapeutic optimism anticipated marked changes in their lives from the study/medication. Finally, some participants predicted the treatment would solve substance-related issues in their communities. These findings highlight the interplay between therapeutic optimism and complex interpretations of RCT objectives among PSUD.

Abstract
Despite the promise of social network research, this method raises important ethical questions regarding privacy and confidentiality. Although researchers and bioethicists have considered research obligations in relation to marginal or vulnerable populations, the views of people who inject drugs (PWIDs) have not been sufficiently considered. To elicit participants' views of research obligations, we conducted in-depth interviews with a subset (n = 40) of active PWIDs enrolled in a large social network study. Findings suggest participants have an expectation of confidentiality but believe this obligation need not be absolute and can be waived if a participant violates community norms or place others at risk. Ethics boards should recognize that marginalized populations are able to articulate complex moral views about privacy and confidentiality. Engaging participants in dialogue about the responsible conduct of research presents an opportunity to correct under- or overestimations of research vulnerabilities when such decisions are restricted to the perspectives of investigators or Institutional Review Board members.

Abstract
Introduction/Objectives: The incidence of hepatitis C (HCV) infection is rising among people who inject drugs (PWID). Even in the context of known HCV prevention and treatment strategies, some PWID remain unengaged in HCV care. This study aimed to identify and characterize experiences and perceptions of PWID regarding the acceptability and effectiveness of HCV testing and treatment at a local syringe service program (SSP). Methods: A total of 36 PWID participated in semi-structured interviews at an SSP in New York City. Interviews were audio-recorded, transcribed, and coded by three coders, following a constructivist grounded theory approach. Relevant themes were identified as they emerged from the data. Results: Interviews with PWID revealed three themes related to the impact of SSPs on HCV care: (1) non-stigmatizing SSP environments, (2) the role of SSPs in improving HCV knowledge, and (3) acceptability of SSPs as sites for HCV care among PWID. Discussion: This paper contributes to the ongoing understanding that SSPs provide a well-accepted source of HCV services for PWID. Participants believed that SSPs are accessible and effective sites for HCV care, and suggested that stigma among PWID continues to affect receipt of HCV care in traditional settings. Conclusions: Understanding attitudes and beliefs of PWID regarding the effectiveness of SSPs as sites for HCV care is crucial for the development of focused strategies to reduce HCV transmission, and to ultimately achieve HCV elimination. Given this, further research is warranted investigating how best to improve HCV care at harm reduction sites such as SSPs.

Abstract
This study examined the association between sex, study risks and willingness to participate in research among a community sample of African Americans. We hypothesized that African American males would be more willing to participate in studies involving both minimal and greater-than-minimal risk. The study sample was recruited through a community engagement program (HealthStreet). Interviewers obtained information on socio-demographic variables and willingness to participate in various research types. We categorized research types into minimal risk and greater- than- minimal risk based on the IRB classification. The study sample comprised 6544 African-Americans; 58.4% were females. About 92.6% of the participants were willing to participate in surveys and 58.1% in research requiring medication use. More males would participate in minimal risk studies requiring review of medical records (males 87.0% vs. females 84.2%, p = 0.0021) and studies involving giving a blood sample (males 84.2% vs. females 81.7%, p = 0.0083). Also, more males would participate in greater than minimal risk studies involving the use of medication (60.5% v. 56.3% p = 0.0007). More males were willing to participate in minimal risk studies (studies involving the review of medical records and giving blood samples) and greater-than-minimal risk study involving the use of medication.

Barriers and motivators to participation and retention in HIV/HCV cohort studies among people who inject drugs: a community consultation in Iran. Subst Abuse Treat Prev Policy 2020; 15:56. [PMID: 32758246 PMCID: PMC7405425 DOI: 10.1186/s13011-020-00298-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 07/22/2020] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND The lack of robust estimates of HIV/HCV incidence among people who inject drugs (PWID) in Iran calls for well-designed prospective cohort studies. Successful recruitment and follow-up of PWID in cohort studies may require formative assessment of barriers PWID are faced with in participation and retention in cohort studies and factors they think may facilitate their engagement in such studies. Using a focus group discussion (FGD) format, we conducted a consultation with PWID in southeast Iran to recognize those barriers and motivators. METHODS Using targeted sampling and through snowball referrals, we recruited PWID (aged≥18, injected in last 6 months) from community-based drop-in centers (DICs), homeless shelters, and through outreach efforts to participate in four FGDs (one women-only). Socio-demographic characteristics, injection behaviors and self-reported HCV/HIV testing and diagnosis history were obtained. Then, a semi-structured FGD guide was applied to explore barriers and motivators to participation and retention in cohort studies among study participants. All FGD sessions were recorded and transcribed verbatim, removing any identifying information. The content of FGDs were analyzed by thematic analysis using an inductive approach. RESULTS In total, 30 individuals (10 women) participated in the study. The median age of participants was 35 (IQR 31-40), with majority (73.3%) reporting injecting drug use within the last month. Only 40.0% reported ever being tested for HCV whereas a larger proportion (63.4%) reported ever being tested for HIV. While the majority were willing to participate in cohort studies, breach of confidentiality, fear of positive test results, perceived required commitment, and marginalization were reported as barriers to participation and retention in such studies. Monetary incentive, the thought of a better life, protection from police interventions and trust between health workers and PWID were addressed as motivators of engagement in cohort studies among PWID. CONCLUSIONS Strategies to enhance data security and reduce stigma associated with injecting drug use along with involving peer workers in research, providing pre and post-test counselling and education and addressing the needs of more marginalized groups potentially through integrated healthcare programs and housing support are among few approaches that may help address barriers and strengthen the motivators for successful cohort studies among this population.

Perceived risks and amelioration of harm in research using mobile technology to support antiretroviral therapy adherence in the context of methamphetamine use: a focus group study among minorities living with HIV. Harm Reduct J 2020; 17:41. [PMID: 32527276 PMCID: PMC7288402 DOI: 10.1186/s12954-020-00384-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Accepted: 05/26/2020] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Methamphetamine use poses a barrier to antiretroviral therapy (ART) adherence. Black and Hispanic men who have sex with men living with HIV (PLWH) shoulder much of the health burden resulting from the methamphetamine and HIV syndemic. Smartphones are nearly ubiquitous in the USA and may be promising vehicles for delivering interventions for ART adherence and drug use cessation. However, the acceptability of using applications to collect sensitive information and deliver feedback in this population has not been adequately explored. OBJECTIVE This study examined minority PLWH's appraisals of the risks of participating in smartphone-based research to promote ART adherence in the context of methamphetamine use and explored their views on appropriate steps to mitigate perceived risks of participation. METHODS Three focus groups were conducted among Black and Hispanic PLWH who use methamphetamine. Of the 13 participants, 5 had previously participated in a smartphone-based observational study of ART adherence and substance use. Discussants provided feedback on smartphone-based research, including receiving probes for HIV medication adherence, mood, and substance use as well as feedback on passive location-tracking for personalized messages. Transcribed audio-recordings were thematically coded and analyzed using the qualitative software MAXQDA. RESULTS Participants expressed confidentiality concerns related to potential unintentional disclosure of their HIV status and methamphetamine use and to possible legal consequences. They additionally expressed concerns around the invasiveness of daily assessments and the potential of methamphetamine use questions to trigger cravings. To mitigate these concerns, they suggested maintaining participant privacy by indirectly asking sensitive questions, focusing on positive behaviors (e.g., number of days sober), allowing user-initiated reporting of location to tailor messages, and ensuring adequate data protections. In addition to financial compensation, participants cited altruism (specifically, continuing a tradition of volunteerism in HIV research) as a motivator for potentially engaging in such research. CONCLUSIONS Minority PLWH have concerns regarding the use of smartphones for ART adherence and methamphetamine sobriety intervention research. However, minority PLWH are likely to participate if studies include appropriate protections against risks to confidentiality and experimental harm and are designed to offer future benefit to themselves and other PLWH.

Abstract
PURPOSE OF REVIEW HIV/AIDS and sexual health research has increasingly relied on online recruitment in recent years. However, as potential online recruitment avenues (e.g., dating and sexual networking applications, websites, social media) have proliferated, navigating this process has become increasingly complex. This paper presents a practical model to guide researchers through online recruitment irrespective of platform. RECENT FINDINGS The CAN-DO-IT model reflects 7 iterative steps based on work by the authors and other investigators: conceptualize scope of recruitment campaign, acquire necessary expertise, navigate online platforms, develop advertisements, optimize recruitment-to-enrollment workflow, implement advertising campaign, and track performance of campaigns and respond accordingly. Online recruitment can accelerate HIV/AIDS research, yet relatively limited guidance exists to facilitate this process across platforms. The CAN-DO-IT model presents one approach to demystify online recruitment and reduce enrollment barriers.

Abstract
Background Aristotle was a seek-test-treat intervention during an outbreak of human immunodeficiency virus (HIV) infection among people who inject drugs (PWID) in Athens, Greece that started in 2011. The aims of this analysis were: (1) to study changes of drug injection-related and sexual behaviors over the course of Aristotle; and (2) to compare the likelihood of risky behaviors among PWID who were aware and unaware of their HIV status. Methods Aristotle (2012–2013) involved five successive respondent-driven sampling rounds of approximately 1400 PWID each; eligible PWID could participate in multiple rounds. Participants were interviewed using a questionnaire, were tested for HIV, and were classified as HIV-positive aware of their status (AHS), HIV-positive unaware of their status (UHS), and HIV-negative. Piecewise linear generalized estimating equation models were used to regress repeatedly measured binary outcomes (high-risk behaviors) against covariates. Results Aristotle recruited 3320 PWID (84.5% males, median age 34.2 years). Overall, 7110 interviews and blood samples were collected. The proportion of HIV-positive first-time participants who were aware of their HIV infection increased from 21.8% in round A to 36.4% in the last round. The odds of dividing drugs at least half of the time in the past 12 months with a syringe someone else had already used fell from round A to B by 90% [Odds Ratio (OR) (95% Confidence Interval-CI): 0.10 (0.04, 0.23)] among AHS and by 63% among UHS [OR (95% CI): 0.37 (0.19, 0.72)]. This drop was significantly larger (p = 0.02) among AHS. There were also decreases in frequency of injection and in receptive syringe sharing in the past 12 months but they were not significantly different between AHS (66 and 47%, respectively) and UHS (63 and 33%, respectively). Condom use increased only among male AHS from round B to the last round [OR (95% CI): 1.24 (1.01, 1.52)]. Conclusions The prevalence of risky behaviors related to drug injection decreased in the context of Aristotle. Knowledge of HIV infection was associated with safer drug injection-related behaviors among PWID. This highlights the need for comprehensive interventions that scale-up HIV testing and help PWID become aware of their HIV status.

Abstract
Endogenous opioid peptides are released at sites of injury, and their cognate G protein-coupled opioid receptors (ORs) are expressed on immune cells. Although drugs of misuse appropriate ORs, conflicting reports indicate immunostimulatory and immunosuppressive activity, in that opioid users have elevated infection risk, opioids activate innate immune cells, and opioids attenuate inflammation in murine T cell-mediated autoimmunity models. The i.v. use of drugs transmits bloodborne pathogens, particularly viruses, making the study of CD8+ T cells timely. From a cohort of nonuser controls and methadone users, we demonstrate, via t-Stochastic Neighbor Embedding and k-means cluster analysis of surface marker expression, that chronic opioid use alters human CD8+ T cell subset balance, with notable decreases in T effector memory RA+ cells. Studying global CD8+ T cell populations, there were no differences in expression of OR and several markers of functionality, demonstrating the need for finer analysis. Purified CD8+ T cells from controls respond to opioids ex vivo by increasing cytoplasmic calcium, a novel finding for OR signal transduction, likely because of cell lineage. CD8+ T cells from controls exposed to μ-OR agonists ex vivo decrease expression of activation markers CD69 and CD25, although the same markers are elevated in μ-OR-treated cells from methadone users. In contrast to control cells, T cell subsets from methadone users show decreased expression of CD69 and CD25 in response to TCR stimulus. Overall, these results indicate a direct, selective role for opioids in CD8+ T cell immune regulation via their ability to modulate cell responses through the opioid receptors and TCRs.
