Awareness and Uptake of Pre-Exposure Prophylaxis (PrEP) for HIV Prevention Among Men who have Sex with Men in Nepal.

Pre-exposure prophylaxis (PrEP) is a highly effective biomedical prevention strategy that remarkably reduces HIV transmission risk. Although PrEP has been available in Nepal since 2019, very little is known about PrEP use among MSM in Nepal. This study aimed to examine PrEP awareness and its use among Nepali MSM and the factors influencing its adoption. A cross-sectional survey was conducted among MSM in Nepal between October and December 2022 (N = 250). Bivariate analysis and logistic regression were performed to determine factors associated with awareness and use of PrEP. In the study population, 59.6% of participants were aware of PrEP, however, only 30.4% of them had utilized it. The odds of PrEP awareness were higher among participants who had completed high school or above (aOR = 4.1; 95% CI = 1.8-9.6), those with health insurance coverage (aOR = 6.9; 95% CI = 2.1-22.3) and had tested for HIV (aOR = 21.2; 95% CI = 8.3-53.9). Similarly, participants who identified as gay (aOR = 3.4; 95% CI = 1.4-8.4), had visited a doctor within the past 6 months (aOR = 2.9; 95% CI = 1.2-6.5), had previously tested for HIV (aOR = 12.3; 95% CI = 3.4-44.7), and had been diagnosed with sexually transmitted infections (aOR = 7.0; 95% CI = 2.5-19.5) were more likely to have used PrEP. Our results highlight the critical importance of healthcare providers engaging in providing care for MSM, including facilitating as well as discussions about PrEP. In addition, there is a pressing need for innovative strategies (e.g., peer educators, social media, online facilitating technologies) to disseminate PrEP knowledge and reduce stigma surrounding PrEP.

High Interest in the Use of mHealth Platform for HIV Prevention among Men Who Have Sex with Men in Nepal.

Mobile technology growth in Nepal offers promising opportunities for using mobile health (mHealth) interventions to facilitate HIV prevention efforts. However, little is known about access and utilization of communication technology and their willingness to use mHealth for HIV prevention services in Nepal. We conducted a cross-sectional respondent-driven sampling survey of 250 MSM in Kathmandu Valley of Nepal from October to December 2022. We collected information on participant characteristics, HIV risk-related behaviors, ownership, or access to and frequency of use of communication technology (phones, tablets, laptops, and computers), and willingness to use mHealth to access HIV prevention services. Descriptive, bivariate, and multivariate linear regression analyses were performed. Almost all participants had smartphones with the internet (231/250, 92.4%) and accessed the internet daily (219/250, 87.6%) on the smartphone (236/250, 94.4%). The median score for willingness to use mHealth for HIV prevention was 10 (IQR: 3 to 17). Willingness to use mHealth was higher among those participants with a high school or above education (ß = 0.223, p = < 0.001), had experienced violence (ß = 0.231, p = 0.006), and had moderate to severe depressive symptoms (ß = 0.223, p = < 0.001). However, monthly income above NPR 20,000 (USD 150) (ß= -0.153, p = 0.008), disclosure of their sexual orientation to anyone (ß= -0.159, p = < 0.007), and worry about being negatively judged by health care workers (ß= -0.136, p = 0.023) were less willing to use mHealth strategies. The findings from this study suggest that there is a high willingness for utilizing mHealth interventions for HIV prevention in MSM population who are at higher risk of HIV acquisition.

Ankle, knee, and elbow arthrography: 2022 survey of Society of Skeletal Radiology members.

OBJECTIVE: To determine the preferred ankle, knee, and elbow arthrography injection techniques for Society of Skeletal Radiology (SSR) members and whether more recently described techniques are gaining acceptance. We also sought to determine whether the concept of knowledge translation might explain differences between the preferred technique, year of fellowship graduation, and year the newer technique was described. MATERIALS AND METHODS: A 29-question survey was created in Qualtrics and submitted to current SSR members to determine if they perform knee, elbow, and ankle arthrography, and if so, the year of fellowship completion and preferred approaches. Survey respondents indicated the starting and ending needle tip positions for three knee, two elbow, and three ankle arthrography approaches using grids placed over provided frontal and lateral radiographs. RESULTS: Two hundred seventy-four SSR members (mean post-fellowship 13 years; range 0-38) completed the survey and performed fluoroscopic-guided knee (93%), elbow (95%), and ankle (75%) arthrography. Preferred approaches included the following: knee lateral subpatellar (43%), anterior (40%); elbow radiocapitellar (74%); ankle anterior/peritendon (70%), lateral mortise (24%). Preference of newer technique was related to fellowship graduation year and publication year for the ankle mortise (26% before, 42% after; p = 0.03) and posterior trans-triceps elbow articles (19% before, 33% after; p < 0.01). The anterior knee approach preference increased from 11% in 2008 to 40% (p ≤ 0.001). CONCLUSION: Nearly twice as many SSR members who graduated after the posterior trans-triceps and ankle mortise techniques were published prefer them for performing arthrography, possibly due to knowledge translation. The preference of the anterior knee arthrography approach has increased nearly fourfold since 2008.

Does MRI alter management in patients 60 years and older with chronic knee pain: correlation with radiographs and clinical parameters.

OBJECTIVE: To determine if MRI altered management in patients ≥ 60 years old with chronic knee pain. MATERIALS AND METHODS: Consecutive patients ≥ 60 years old with knee MRI and radiographs within 90 days were included. Exclusion criteria included mass/malignancy, recent trauma, and infection. Standing AP and PA flexion views were evaluated using Kellgren-Lawrence (KL) and International Knee Documentation Committee (IKDC) scales. Pertinent clinical history was recorded. MRIs were considered to alter management if subchondral fracture was identified or subsequent arthroscopy was performed due to an MRI finding. RESULTS: Eighty-five knee MRI/radiograph exams were reviewed; mean 68.2 years (60-88), 47:38 F:M. Twenty knee MRIs (24%) had either a subchondral fracture (n = 9) or meniscal tear (n = 11) prompting arthroscopy. On PA flexion view, 0/20 of these studies had KL grade 4 and 70% (14/20) had KL grade 0-1 compared to the remaining MRIs having 15.4% (10/65) KL grade 4 and 38.5% (25/65) KL grade 0-1 (p = 0.03). A 10-pack-year tobacco history, 38% vs 18%, was associated with a subchondral fracture or arthroscopy (p = 0.06). Subchondral fractures were more prevalent in older patients (mean 72.4 vs 67.7 years; p = 0.03). CONCLUSION: In patients ≥ 60 years old with chronic knee pain, MRI altered management in ~ 24% of cases; 70% in patients with KL grade 0-1, and none in patients with KL grade 4. MRI may benefit older patients with minimal osteoarthritis but not those with end-stage disease. Patients with ≥ 10 pack years of smoking may also benefit from MRI.

Osteochondral Lesions of the Ankle and Foot.

Osteochondral lesions (OCLs) in the ankle are more common than OCLs of the foot, but both share a similar imaging appearance. Knowledge of the various imaging modalities, as well as available surgical techniques, is important for radiologists. We discuss radiographs, ultrasonography, computed tomography, single-photon emission computed tomography/computed tomography, and magnetic resonance imaging to evaluate OCLs. In addition, various surgical techniques used to treat OCLs-debridement, retrograde drilling, microfracture, micronized cartilage-augmented microfracture, autografts, and allografts-are described with an emphasis on postoperative appearance following these techniques.

High Interest in Long-acting Injectable Pre-exposure Prophylaxis (LAI-PrEP) for HIV Prevention Among Men Who Have Sex With Men (MSM): Result From A Nationwide Survey in Malaysia.

The recent approval of long-acting injectable cabotegravir (CAB-LA) as PrEP for HIV prevention could be an attractive alternative for MSM, particularly among those who face barriers to adherence using the oral pill. This study reports on the awareness of long-acting injectable PrEP (LAI-PrEP) and factors associated with interest in LAI-PrEP use among a nationwide sample of MSM in Malaysia. An online cross-sectional survey was conducted between August and September 2021 to explore perspectives on PrEP modalities among Malaysian MSM (N = 870). Convenience sampling was used to recruit participants using ads on two platforms hornet and facebook. While only 9.1% of the study participants were aware of LAI-PrEP, the majority had heard of oral PrEP (80.9%). After giving a description of it, a large majority (86.6%) expressed interest in using it if made accessible. Those who had a prior history of HIV testing (aOR = 1.9; 95% CI = 1.2-3.2) were more likely to use LAI-PrEP. Interestingly, despite the concerns related to potential high cost (aOR = 3.4; 95% CI = 2.1-5.5) and long-term side effects (aOR = 1.9; 95% CI = 1.2-3.1), the majority of the participants were interested in using LAI-PrEP. Those who were afraid of (or disliked) syringes were less interested in using it (aOR = 0.2; 95% CI; 0.1-0.4). In the recent context that LAI-PrEP was shown to be safe and effective at preventing HIV, our results indicate its potential relevance as an additional PrEP option that could accelerate the uptake and scale-up of PrEP. However, it is crucial to conduct future research urgently to improve the understanding of strategies that could enhance the accessibility, acceptability, and affordability of LAI-PrEP for MSM in low- and middle-income countries, including Malaysia.

Limited Risk Compensation Among Women Who Inject Drugs: Results From the Project Sexual Health Equity Preexposure Prophylaxis Demonstration Study in Philadelphia.

ABSTRACT: The impact of preexposure prophylaxis uptake on sexual and injection-related behaviors among women who inject drugs is poorly understood. Over 24 weeks, preexposure prophylaxis uptake among women who inject drugs was associated with increased sharing of injection equipment but not syringes and no changes in condomless sex, providing limited evidence of risk compensation in this vulnerable population.

Postoperative Ankle Imaging, 2022.

Postoperative ankle imaging requires knowledge of the underlying surgical techniques, the usefulness of various imaging modalities, as well as an appreciation for the desired clinical outcomes. Surgical procedures discussed in this article are tibiotalar fracture fixation, tibiotalar, subtalar, and tibiotalocalcaneal arthrodesis, total ankle arthroplasty, talar osteochondral lesion repair and grafting, lateral ligamentous repair and reconstruction, and peroneal and Achilles tendon repair and reconstruction. Imaging can play a vital role in determining if the expected outcome has been achieved and identifying complications, with particular emphasis placed on the use of radiographs, computed tomography (including weight-bearing), magnetic resonance imaging, and ultrasonography.

Mobile Health Technology Use and the Acceptability of an mHealth Platform for HIV Prevention Among Men Who Have Sex With Men in Malaysia: Cross-sectional Respondent-Driven Sampling Survey.

BACKGROUND: The growth in mobile technology access, utilization, and services holds great promise in facilitating HIV prevention efforts through mobile health (mHealth) interventions in Malaysia. Despite these promising trends, there is a dearth of evidence on the use of mHealth platforms that addresses HIV prevention among Malaysian men who have sex with men. OBJECTIVE: The goal of this study was to gain insight into (1) access and utilization of communication technology (eg, landline phone, internet, mobile phone), (2) acceptability of mHealth-based interventions for HIV prevention services, and (3) preferences regarding the format and frequency of mHealth interventions among Malaysian men who have sex with men. METHODS: We conducted a cross-sectional survey with Malaysian men who have sex with men between July 2018 and March 2020. Participants were recruited using respondent-driven sampling in the Greater Kuala Lumpur region of Malaysia. We collected information on demographic characteristics, HIV risk-related behaviors, access to and the frequency of use of communication technology, and acceptability of using mHealth for HIV prevention using a self-administered questionnaire with a 5-point scale (1, never; 2, rarely; 3, sometimes; 4, often; 5, all the time). RESULTS: A total of 376 men participated in the survey. Almost all respondents owned or had access to a smartphone with internet access (368/376, 97.9%) and accessed the internet daily (373/376, 99.2%), mainly on a smartphone (334/376, 88.8%). Participants on average used smartphones primarily for social networking (mean 4.5, SD 0.8), followed by sending or receiving emails (mean 4.0, SD 1.0), and searching for health-related information (mean 3.5, SD 0.9). There was high acceptance of the use of mHealth for HIV prevention (mean 4.1, SD 1.5), including for receiving HIV prevention information (345/376, 91.8%), receiving medication reminders (336/376, 89.4%), screening and monitoring sexual activity (306/376, 81.4%) or illicit drug use (281/376, 74.7%), and monitoring drug cravings (280/376, 74.5%). Participants overwhelmingly preferred a smartphone app over other modalities (eg, text, phone call, email) for engaging in mHealth HIV prevention tools. Preference for app notifications ranged from 186/336 (53.9%), for receiving HIV prevention information, to 212/336 (69.3%), for screening and monitoring sexual activity. Acceptance of mHealth was higher for those who were university graduates (P=.003), living in a relationship with a partner (P=.04), engaged in sexualized drug use (P=.01), and engaged in receptive anal sex (P=.006). CONCLUSIONS: Findings from this study provide support for developing and deploying mHealth strategies for HIV prevention using a smartphone app in men who have sex with men-a key population with suboptimal engagement in HIV prevention and treatment.

Using nominal group technique to identify barriers and facilitators to preventing HIV using combination same-day pre-exposure prophylaxis and medications for opioid use disorder.

BACKGROUND: Preventing HIV transmission among people who inject drugs (PWID) is a key element of the US Ending the HIV Epidemic strategy and includes both pre-exposure prophylaxis (PrEP) and medications for opioid use disorder (MOUD). While both lead to decreases in HIV transmission, MOUD has other social and health benefits; meanwhile, PrEP has additional HIV prevention advantages from sexual risk and the injection of stimulants. However, these medications are often prescribed in different settings and require multiple visits before initiation. Strategies to integrate these services (i.e., co-prescription) and offer same-day prescriptions may reduce demands on patients who could benefit from them. METHODS: Nominal group technique, a consensus method that rapidly generates and ranks responses, was used to ascertain barriers and solutions for same-day delivery of PrEP and MOUD as an integrated approach among PWID (n = 14) and clinical (n = 9) stakeholders. The qualitative portion of the discussion generated themes for analysis, and the ranks of the proposed barriers and solutions to the program are presented. RESULTS: The top three barriers among PWID to getting a same-day prescription for both PrEP and MOUD were (1) instability of insurance (e.g., insurance lapses); (2) access to a local prescriber; and (3) client-level implementation factors, such as lack of personal motivation. Among clinical stakeholders, the three greatest challenges were (1) time constraints on providers; (2) logistics (e.g., coordination between providers and labs); and (3) availability of providers who can prescribe both medications. Potential solutions identified by both stakeholders included pharmacy delivery of the medications, coordinated care between providers and health care systems (e.g., case management), and efficiencies in clinical care (e.g., clinical checklists), among others. CONCLUSIONS: Implementing and sustaining a combined PrEP and MOUD strategy will require co-training providers on both medications while creating efficiencies in systems of care and innovations that encourage and retain PWID in care. Pilot testing the co-prescribing of PrEP and MOUD with quality performance improvement is a step toward new practice models.

Clinical and demographic differences in the willingness to use self-administered at-home COVID-19 testing measures among persons with opioid use disorder.

Background: COVID-19 is disproportionately affecting disadvantaged populations, including persons with opioid use disorder (OUD). Persons with OUD are at greater risk for direct (e.g., COVID-19 diagnosis, severe symptoms) and indirect consequences (relapse, overdose) of COVID-19. Given stay at home orders, at-home testing options may serve as a viable tool to curb the increase in COVID-19 transmission and adverse effects of COVID-19. Methods: From May to September 2020, we surveyed 110 persons in treatment for OUD about their willingness to use various self-administered at-home COVID-19 testing measures. Participants were stratified by age, gender, and racial-ethnic identity to observe differences in willingness to use COVID-19 tests. The three COVID-19 tests included a throat swab sample, a saliva-based sample, and a blood prick test. Results: A high willingness to use at-home COVID-19 tests was observed in patients in treatment for OUD. A greater proportion of females were willing to use a saliva-based test; greater proportions of White participants were willing to use a saliva based COVID-19 test compared to racial-ethnic minorities. Older aged participants (≥45 years old) reported greater rates of willingness to use a self-administered at home blood prick test for COVID-19. Conclusions: At-home testing measures for COVID-19 appear highly acceptable among people with OUD.

The Pre-exposure Prophylaxis (PrEP) Care Cascade in People Who Inject Drugs: A Systematic Review.

Injection drug use is a key risk factor for the transmission of HIV. Prevention strategies, such as the use of pre-exposure prophylaxis (PrEP), are effective at reducing the risk of HIV transmission in people who inject drugs (PWID). Following PRISMA guidelines, a literature search was conducted to identify the current state of the PrEP care cascade in PWID. Twenty-three articles were evaluated in this systematic review. A decline in engagement throughout the stages of the PrEP care cascade was found. High awareness and willingness to use PrEP was found, yet PrEP uptake was relatively low (0-3%). There is a lack of research on interventions to increase engagement of PrEP across all levels of the care cascade in PWID. Implications from the interventions that have been published provide insight into practice and public policy on efficacious strategies to reduce HIV incidence in PWID. Our findings suggest that more efforts are needed to identify and screen PWID for PrEP eligibility and to link and maintain them with appropriate PrEP care.

Use of Pre-exposure Prophylaxis Among People Who Inject Drugs: Exploratory Findings of the Interaction Between Race, Homelessness, and Trust.

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.

Response to the COVID-19 Outbreak in Urban Settings in China.

The COVID-19 outbreak in China was devastating and spread throughout the country before being contained. Stringent physical distancing recommendations and shelter-in-place were first introduced in the hardest-hit provinces, and by March, these recommendations were uniform throughout the country. In the presence of an evolving and deadly pandemic, we sought to investigate the impact of this pandemic on individual well-being and prevention practices among Chinese urban residents. From March 2-11, 2020, 4607 individuals were recruited from 11 provinces with varying numbers of COVID-19 cases using the social networking app WeChat to complete a brief, anonymous, online survey. The analytical sample was restricted to 2551 urban residents. Standardized scales measured generalized anxiety disorder (GAD), the primary outcome. Multiple logistic regression was conducted to identify correlates of GAD alongside assessment of community practices in response to the COVID-19 pandemic. We found that during the COVID-19 pandemic, the recommended public health practices significantly (p < 0.001) increased, including wearing facial mask, practicing physical distancing, handwashing, decreased public spitting, and going outside in urban communities. Overall, 40.3% of participants met screening criteria for GAD and 49.3%, 62.6%, and 55.4% reported that their work, social life, and family life were interrupted by anxious feelings, respectively. Independent correlates of having anxiety symptoms included being a healthcare provider (aOR = 1.58, p < 0.01), living in regions with a higher density of COVID-19 cases (aOR = 2.13, p < 0.01), having completed college (aOR = 1.38, p = 0.03), meeting screening criteria for depression (aOR = 6.03, p < 0.01), and poorer perceived health status (aOR = 1.54, p < 0.01). COVID-19 had a profound impact on the health of urban dwellers throughout China. Not only did they markedly increase their self- and community-protective behaviors, but they also experienced high levels of anxiety associated with a heightened vulnerability like depression, having poor perceived health, and the potential of increased exposure to COVID-19 such as living closer to the epicenter of the pandemic.

Engagement in Harm Reduction Strategies After Suspected Fentanyl Contamination Among Opioid-Dependent Individuals.

The evolving opioid epidemic in the United States has increased drug-related overdose rates exponentially (Centers for Disease Control and Prevention in Opioid overdose, 2020c, https://www.cdc.gov/drugoverdose/data/otherdrugs.html#:~:text=Polysubstance%20drug%20use%20occurs%20with,or%20other%20non%2Dopioid%20substances ). Fentanyl, a synthetic opioid, has recently fueled the epidemic, increasing overdose death rates (Centers for Disease Control and Prevention in Drug overdose deaths involving fentanyl, 2011-2016, 2019a, https://www.cdc.gov/nchs/data/nvsr/nvsr68/nvsr68_03-508.pdf ). Harm reduction strategies (drug checking, naloxone administration, etc.) are at the forefront of preventing opioid-related overdoses in high-risk populations (Kennedy et al. in Drug Alcohol Depend 185:248-252, 2018, https://doi.org/10.1016/j.drugalcdep.2017.12.026 ; Laing et al. in Int J Drug Policy 62:59-66, 2018, https://doi.org/10.1016/j.drugpo.2018.10.001 ). Little is known, however, about how people who inject drugs (PWID) may modify their drug use behaviors after suspected fentanyl contamination in their drugs. We conducted a cross-sectional survey among 105 opioid-dependent PWID enrolled in a methadone maintenance program. We assessed their willingness to engage in various harm reduction methods (i.e., slowing down drug use, not using drugs, carrying naloxone, using with someone who has naloxone) after suspected fentanyl contamination of their drugs. In a multivariable analysis, participants who were white, low-income, polysubstance users, and had previously experienced an overdose or had previously administered naloxone were more likely to report a willingness to engage in harm reduction measures. These findings provide an evidence-based understanding of PWID's engagement in harm reduction behaviors after suspecting potential fentanyl exposure as well as a basis for tailoring intervention strategies in the context of fentanyl-adulterated markets.

The Impact of COVID-19 on Access to HIV Prevention Services Among Opioid-Dependent Individuals.

The COVID-19 pandemic has necessitated restrictive orders and programmatic changes that may be associated with disruptions in services, including those for opioid-dependent people who inject drugs (PWID). This study aims to assess the impact of COVID-19 pandemic on access to and utilization of various HIV prevention services among PWID with opioid use disorder (OUD). We interviewed 110 PWID enrolled in medication for opioid use disorder (MOUD) treatment (e.g., methadone) between May and October, 2020 to identify if this sample experienced changed in access to the following services due to the COVID-19 pandemic: (a) HIV or sexually transmitted infection (STI) testing, (b) pre-exposure prophylaxis (PrEP) services, (c) HIV counselor or doctor appointments, and (d) clean injection equipment. A majority of the sample reported that COVID-19 had not changed their access to HIV testing or access to STI testing. Almost half of the sample reported that getting an appointment with a doctor decreased due to COVID-19. Participants reported that access to a lab or blood testing, access to injection equipment, and sessions with a case manager or counselor decreased. One-fourth of the 32 participants who were taking PrEP before the onset of COVID-19 reported that they had trouble getting their PrEP prescription due to COVID-19, and some reported that they had difficulty getting the PrEP prescription filled at their pharmacy. Our results indicate that PWID did not experience reduced access to HIV or STI testing, but difficulties in obtaining appointments with HIV counselors or doctors and limited access to PrEP were presented. Innovative strategies are needed to reduce the adverse effects of COVID-19 on HIV prevention among PWID.

Purposeful Fentanyl Use and Associated Factors among Opioid-Dependent People Who Inject Drugs.

Introduction: In recent years, opioid-related mortality has increased steadily in the United States. Fentanyl, a synthetic opioid, has been a primary driver of the current wave of overdose-related deaths. Little is known, however, about fentanyl use among opioid-dependent people who inject drugs (PWID). We, therefore, sought to characterize purposeful fentanyl use among PWID. Methods: A cross-sectional survey was administrated to 104 opioid-dependent PWID on methadone who self-reported drug- or sex-related risk behaviors. Participants were recruited between July 2018 and October 2019 from a methadone clinic in New Haven, Connecticut. Multivariable logistic regressions were used to identify independent correlates of purposeful fentanyl use. Results: Overall, 43.2% and 22.1% of the participants reported any (lifetime) or recent (past 30 days) purposeful fentanyl use, respectively. Independent correlates of any purposeful fentanyl use were younger age (aOR= 0.94; p = 0.021), recent daily injection (aOR= 3.52; p = 0.047), recent cocaine use (aOR= 3.54; p = 0.041), and moderate/severe depression (aOR= 3.82; p = 0.028). Independent correlates of recent purposeful fentanyl use were moderate/severe depression (aOR= 10.94; p = 0.031), recently sharing injection equipment (aOR= 2.96; p = 0.044), and recently engaging in transactional sex (aOR= 3.60; p = 0.026). Conclusions: These findings indicate that opioid-dependent PWID on methadone remain at increased risk for overdose given the high prevalence of ongoing purposeful fentanyl exposure. Interventions to reduce the harms associated with fentanyl use should target young PWID and active fentanyl users, with an emphasis on achieving adequate methadone dosage and screening and treating depression in methadone-maintained patients who preferentially seek fentanyl.

Using individual stated-preferences to optimize HIV self-testing service delivery among men who have sex with men (MSM) in Malaysia: results from a conjoint-based analysis.

BACKGROUND: HIV self-testing (HIVST) has the potential to improve HIV testing uptake and frequency for key populations like MSM who experience multiple barriers accessing clinic-based HIV testing. In the absence of HIVST in Malaysia, there is no guidance to inform HIVST delivery. This study investigated the acceptability of HIVST and preferences about the HIVST service delivery approaches using a standardized stated preference method. METHODS: A cross-sectional online survey conducted between January and April 2019 assessed the interest in HIVST in 544 MSM in Malaysia. Participants ranked eight hypothetical HIVST service delivery program elements with varied combinations of six, two-level HIVST service delivery program attributes (cost, privacy, accuracy, kit collection site, kit type, and testing support). SPSS conjoint procedure was used to estimate the relative importance of each attribute and preference across eight possible HIVST service delivery programs. RESULTS: Overall, 70.4% had previously tested for HIV, and of those, 64.0% had done so in the past 6 months (45.0% of all participants). Of all the participants, 25.2% reported having used HIVST previously. The acceptability for HIVST service delivery models ranged from 44.9 to 77.1%, with mean acceptability of 56.2% across the eight hypothetical HIVST distribution scenarios. The HIVST service delivery scenario with the highest acceptability had the following attributes: no cost (free), anonymity (name not required), 99-100% accuracy, home-delivered, fingerstick, and testing support using telephone hotline or texting. HIVST cost was the most important attribute (relative importance score: RIS = 19.30) associated with acceptability, followed by anonymity (RIS = 18.41), accuracy (RIS = 17.33), kit delivery (RIS = 16.99), fingerstick kit (RIS = 15.86), and support (RIS = 12.08). CONCLUSIONS: Acceptability for HIVST in Malaysian MSM was high but differed markedly by a number of HIVST delivery scenarios and attributes. These findings could be relevant as the Malaysian Ministry of Health is in the process of developing a regulatory framework for ensuring the quality of kits, as well as policies supporting safe use while broader implementation under national AIDS programs.

Use of Smartphone to Seek Sexual Health Information Online Among Malaysian Men Who Have Sex with Men (MSM): Implications for mHealth Intervention to Increase HIV Testing and Reduce HIV Risks.

In settings where stigma and discrimination toward men who have sex with men (MSM) are high or illegal, like in Malaysia, innovative methods to anonymously reach them are urgently needed. The near ubiquitous availability of mobile technology, including smartphones, has the potential to open new frontiers (such as mHealth) to prevent HIV and other sexually transmitted infections (STIs). The extent to which MSM use mHealth tools for HIV and STI prevention in the Malaysia context, however, is unknown. A cross-sectional online survey in 622 Malaysian MSM was conducted between July and November 2017. Participants were recruited via advertisements on mobile apps frequently used by MSM. In addition to demographic, smartphone access and utilization, and other information were assessed using logistic regression to determine factors associated with the use of a smartphone to search for online sexual health information. Nearly all (99.2%) participants owned a smartphone, with 63% reported having used one to seek sexual health information, including HIV/STIs. Overall, 96% used smartphones to find sexual partners, with high levels of HIV risk behavior reported. Independent correlates of smartphone use to seek online sexual health information included older age (aOR 0.943, p = 0.005), higher education (aOR 2.14, p = 027), recent (past year) HIV testing (aOR 3.91, p = 0.026), and seeking sexual partners using geosocial networking apps (aOR 5.58, p = 0.006). These findings suggest high smartphone use by high-risk MSM to seek sexual health information and suggests that mHealth strategies may be an effective strategy to engage MSM in HIV prevention activities.

HIV Sero-Status Non-disclosure Among HIV-Infected Opioid-Dependent Individuals: The Roles of HIV-Related Stigma, Risk Behavior, and Social Support.

HIV sero-status disclosure among people living with HIV (PLWH) is an important component of preventing HIV transmission to sexual partners. Due to various social, structural, and behavioral challenges, however, many HIV-infected opioid-dependent patients do not disclose their HIV status to all sexual partners. In this analysis, we therefore examined non-disclosure practices and correlates of non-disclosure among high-risk HIV-infected opioid-dependent individuals. HIV-infected opioid-dependent individuals who reported HIV-risk behaviors were enrolled (N = 133) and assessed for HIV disclosure, risk behaviors, health status, antiretroviral therapy (ART) adherence, HIV stigma, social support and other characteristics. Multivariable logistic regression was used to identify significant correlates of non-disclosure. Overall, 23% reported not disclosing their HIV status to sexual partners, who also had high levels of HIV risk: sharing of injection equipment (70.5%) and inconsistent condom use (93.5%). Independent correlates of HIV non-disclosure included: being virally suppressed (aOR 0.19, p = 0.04), high HIV-related stigma (aOR 2.37, p = 0.03), and having multiple sex partners (aOR 5.87, p = 0.04). Furthermore, a significant interaction between HIV-related stigma and living with family/friends suggests that those living with family/friends were more likely to report not disclosing their HIV status when higher levels of perceived stigma was present. Our findings support the need for future interventions to better address the impact of perceived stigma and HIV disclosure as it relates to risk behaviors among opioid-dependents patients in substance abuse treatment settings.
