Summary: Russia's invasion of Ukraine on February 24, 2022, followed by Ukraine's Martial law, has disrupted the routine delivery of healthcare services, including opioid agonist treatment (OAT) programs. Directors (chief addiction treatment physicians) of these programs in each region had flexibility with implementing a series of adaptations to their practice to respond to war disruptions like mass internal displacement and legislation updates allowing more flexibility with OAT distribution policies and take-home dosing regulations. We conducted 8 in-depth interviews with directors from seven regions of Ukraine to describe their experiences providing OAT during a specific time during the war and the local crisis-response approach under the emergency policy updates. We categorized their experiences according to the level of exposure to conflict in each region and displacement of patients across the country, which may provide future guidance for OAT provision during the conflict.

Methadone treatment is prescribed by evidence-based medicine as the most effective tool for the treatment of opioid addiction. Its implementation into high-need prison settings worldwide has been met with challenges, particularly in Eastern Europe and Central Asia where the opioid epidemic continues to expand. To address these impasses to intervention translation, we turn to post-structural approaches to policy analysis. These approaches open space for (re)thinking the ways that translated interventions emerge locally, by treating policy texts as social practices that make interventions in specific, sometimes unexpected, ways. We leverage Carol Bacchi’s post-structuralist analytic framework to interrogate how the object of methadone is constituted in Kyrgyz prisons through an analysis of the national legislative document, the “Government Program,” which provides the legislative basis for opioid addiction treatment administration in the Kyrgyz Republic. Rather than the medicalized methadone for the treatment of opioid use disorder, contained in the distinct objectivization of methadone emerging from this policy text, is the previously unexamined assumption that methadone is a particular type of governance. We describe a methadone object tied up with the shifting social structures that govern Kyrgyz prisons, divided between formal (state-run) and informal (prisoner-run) governance. In Kyrgyz prisons, where opioid policy discourse produces a divide between formal and informal governance, methadone emerges as a tool of the formal prison administration to regain control of the prisons from the practices of prisoner subculture. Although this study takes the Kyrgyz case as an example, the enactment of methadone as formal governance is likely to resonate throughout Eastern Europe and Central Asia, where there is a strong legacy of self-governing prisons. We conclude with a call for global health policymakers to consider how opioid addiction treatment is constituted within local governing relations, in ways that may depart sharply from the evidence base.

Inaccurate HIV risk perception is common among men who have sex with men (MSM). Accurate self-perceived risk and HIV testing are closely related and are essential in promoting HIV treatment cascade succeed. This cross-sectional study aims to 1) explore HIV risk perception and its associated sexual behaviors, 2) identify associated factors with HIV testing among Chinese MSM. Participants were recruited to an anonymous online survey in 2019 via an MSM social application. The questionnaire included sexual behaviors, HIV testing history, and the use of HIV prevention services. Logistic regression was used to explore the factors associated with higher risk perceptions and HIV testing in the past 12 months. Total 431 MSM were recruited, 73.3% had been tested for HIV in the past year and 47.80% of MSM self-reported in the high-risk group. MSM who perceived a higher risk (AOR=3.42, 95% CI:2.06-5.68), had multiple sexual partners (AOR=2.60, 95% CI:1.40-4.83), knew sex partner’s HIV status (AOR=7.96, 95% CI:4.33-14.65), and have STI diagnosis (AOR=2.76, 95% CI:1.10-6.95), were more likely to have been tested. Risk perception and sexual behavior were associated with HIV testing. Culturally adapted, theory-driven education programs are expected to utilize in improving MSM’s risk perception accuracy and HIV testing.

Methadone maintenance treatment (MMT) is the most effective and cost-effective strategy to control HIV in Central Asian countries, where the epidemic is concentrated among people who inject drugs (PWID) who use opioids.Using data from a prospective observational database of all people initiated on MMT in Kyrgyzstan since 2008, we analyzed a more contemporary subset of data for all persons receiving MMT from January 2017 through June 2021 after the national treatment guidelines were changed. Retention on MMT was assessed at 1, 6, 12, and 24 months and predictive variables included were dosage levels, HIV status, and type of clinical setting using survival analysis. Predictors of treatment dropout were estimated using Cox multivariate regression models.Among the 940 MMT patients, the proportion receiving low (40mg), medium (40-85mg), and high (85mg) dosage levels was 37.9%, 42.2%, and 19.9%, respectively. Increasing MMT dosage level was significantly (p0.0001) correlated with retention at 1 (90%, 98%, 100%), 6 (42%, 63%, 95%), 12 (33%, 55%, 89%), and 24 (16%, 45%, 80%) months, respectively, with no differences between community and correctional settings. Significant predictors of dropout at 12 months included low (aHR=8.0; 95%CL=5.8-11.0) and medium (aHR=3.5; 95%CL=2.5-4.9) methadone dosage level relative to high dose, receiving MMT in three administrative regions relative to the capital Bishkek, and lower in the tuberculosis-specialized clinic in Bishkek. Clients with HIV receive higher average MMT doses (79.5mg vs 63.1mg; p0.0001), but MMT retention did not differ after controlling for dosage in this group.The proportion of patients receiving optimal dosage was low (19.9%). An implementation strategy that focused on getting a larger proportion of MMT on the optimal dosage to promote retention could potentially improve the quality of existing treatment and promote further scale-up of MMT in Kyrgyzstan.

Tajikistani migrants who work in Russia and acquire HIV seldom receive HIV treatment while in Russia. Barriers to engagement in the HIV care cascade were identified from in-depth, semi-structured interviews with purposefully sampled Tajikistani migrants (n = 34) with HIV who had returned from Russia. Data were analyzed using thematic analysis, drawing from Putnam's theory of social capital, showing how bridging and bonding social capital relate to poor engagement in HIV care. We identified three barriers to Tajikistani migrants' movement through the HIV care cascade: (1) Russia's migration ban on people with HIV interrupts social capital accumulation and prevents access to HIV treatment within Russia; (2) mistrust of authority figures, including healthcare providers, leads to avoiding treatment and harm-reduction services upon their return to Tajikistan; and (3) because of pervasive discrimination, Tajikistani migrants form weak social ties while in Russia, which exacerbates risk, including with Russian citizens, and deters engagement with HIV care. Deploying a treatment as prevention strategy and abolishing Russia's ban on people with HIV would improve both individual and public health.

Tajikistan, a country of approximately nine million people, has a relatively small but quickly growing HIV epidemic. No peer-reviewed study has assessed factors associated with HIV, or associated risk factors, among female sex workers (FSWs) in Tajikistan. The purpose of the current study is to elucidate the factors associated with HIV status and risk factors in the Tajikistani context and add to the scant literature on risk factors among FSWs in Tajikistan and Central Asia. We used cross-sectional data from an HIV bio-behavioral survey (BBS) conducted among FSWs in the Republic of Tajikistan ( n = 2174) in 2017. Using Respondent Driven Sampling Analysis Tool software, we calculated the prevalence of HIV, diagnosed cases, linkage to antiretroviral therapy (ART), and the prevalence of syphilis for FSWs in Tajikistan. Prevalence data were adjusted for network size and any clustering effects in the network. Further, using univariate and multivariable logistic regression, we determined correlates of HIV-positive status. Results were as follows: Of all FSWs in Tajikistan, 2.6% (95% CI: 1.7–3.8%) are HIV positive, 2.3% (95% CI: 1.4–3.5%) are diagnosed and aware of their status, and 2.0% (95% CI: 1.2–3.1%) are on ART. About 5.7% (95% CI: 4.5–7.4%) of FSWs in Tajikistan have ever had syphilis, and 0.8% (95% CI: 0.4–1.3%) have active syphilis infections. The epidemic of injection drug use was found to be strongly synergistic with HIV infection as having had sex with a person who injects drugs was shown to be strongly associated with HIV-positive status (OR: 5.2; 95% CI: 2.6–10.2) in the multivariable model. While this study estimates that HIV prevalence among Tajikistani FSWs is relatively low, it is likely an underestimated due to selection and social desirability biases. To curb the small, but potentially volatile, HIV epidemic among FSWs, the government should consider targeted testing and linkage-to-care efforts for FSWs who inject drugs or who have people who inject drugs partners. Services should also be prioritized in Gorno-Badakhshan, which has a higher number of FSWs per capita relative to other regions. Additionally, the link between HIV and experiences of stigma, violence, and discrimination against FSWs should motivate advocates to protect Tajikistani FSWs from these experiences.

The ongoing overdose crisis continues to adversely affect adolescents and young adults (AYAs) and has led to numerous preventable deaths. Medications for opioid use disorder (MOUD), such as methadone, buprenorphine, and naltrexone, have the potential to reduce opioid use and associated harms; however, there are concerns that AYAs lack access to these potentially life-saving medications.To systematically review peer-reviewed literature on MOUD access and associated factors to synthesize strategies that can improve MOUD access for AYAs who use opioids.The MEDLINE, Embase, PsycINFO, CINAHL, Sociological Abstracts, Web of Science, and Global DissertationsTheses databases were searched from database inception until May 3, 2021. English, French, Russian, or Spanish peer-reviewed studies that evaluated the availability, prescription receipt, or initiation of MOUD were eligible for inclusion.This systematic review identified 37 cohort (n = 17), cross-sectional (n = 15), and qualitative (n = 5) studies that accounted for 179 785 AYAs (mean [SD] age, 24.4 [3.9] years; 148 779 [85%] were female; 67 771 [84%] were White) and examined access to methadone (30 studies), buprenorphine (26 studies), and naltrexone (10 studies). Findings reinforce concerns that AYAs were less likely to access MOUD and suggest that adolescents were more likely to receive naltrexone or buprenorphine-naloxone, which have a lower potential for abuse, in comparison with young adults. This review also identified other factors that were associated with MOUD access, including criminal justice involvement, residing in the US South, living in a limited-income area, Black race, and Hispanic or Latino ethnicity, suggesting ways in which treatment services may be improved to increase MOUD access and meet the treatment goals of AYAs.This systematic review found gaps in MOUD access between AYAs and non-AYA populations in addition to differences in MOUD access between adolescents and young adults. Considering that existing clinical guidelines recommend the use of MOUD among AYAs, and in light of the increasing number of opioid toxicity deaths, there is a need to improve MOUD access among AYAs by reducing barriers to MOUD and providing AYAs with a continuum of health and social supports alongside MOUD. Future research into ways to encourage MOUD uptake among AYAs may improve the treatment and health outcomes for this population.

The prevalence of HIV infection among men who have sex with men (MSM) in China has increased in recent years. Regular HIV testing is a key prevention strategy for identifying HIV infections among MSM. Informed by the theory of triadic influence, we aimed to determine individual, social and environmental factors associated with regular HIV testing behavior. Regular HIV testing is defined as taking an HIV test every 3 to 6 months. Both an online survey and a face-to-face survey was administered to MSM in China. Logistic regression was used to examine associations with testing behavior. 500 MSM were surveyed, the prevalence of regular testing was 56.4%. In the final model, age of first sexual intercourse, self-efficacy, perceived risk, number of partners, orientation disclosure, knowledge of HIV testing, behavioral intention and HIV relevant behaviors (sexually transmitted infection testing history) were associated with regular HIV testing; social stream characteristics had stronger associations with regular testing than individual and environmental factors. Findings implicated that interventions aimed at improving the effective counseling service from healthcare providers and the medical environment and intrapersonal changes should be combined to encourage MSM to have their first HIV test and to keep coming back at regular intervals.

BACKGROUND. While advances in HIV prevention and treatment have changed the epidemic for gay and bisexual men, another epidemic faces this population. Gay and bisexual men represent one of the highest risk groups for depression, which potentially poses quality-of-life and public health challenges comparable to those of HIV. The present study seeks to inform comprehensive care for sexual minority men by estimating and comparing the morbidity of HIV and depression for US gay and bisexual men. METHODS. In 2018, weighted counts of gay and bisexual men living with HIV and depression were derived from the CDC’s Medical Monitoring Project and the National Survey on Drug Use and Health, respectively. Years lived with disability for HIV and depression come were calculated using the Global Burden of Disease Study’s disability weights. FINDINGS. Among gay and bisexual adult men in the US, the prevalence of past-year major depressive episodes is 14.17%, while the prevalence of HIV is 11.52%. We estimate that in calendar year 2015, major depressive episodes imposed 85,361 (95% CI: 58,293–112,212) years lived with disability among US adult gay and bisexual men, whereas HIV posed 42,981 (95% CI: 36,221–49,722) years lived with disability. INTERPRETATION. This analysis shows that depression morbidity currently exceeds that for HIV among US adult gay and bisexual men. While gay and bisexual men are frequently understood to be a high-risk population for HIV, including in guidelines for HIV prevention and treatment, the present analysis suggests that this population should also be considered high-risk for depression.

The volatile opioid epidemic is associated with higher levels of opioid use disorder (OUD) and negative health outcomes in adolescents and young adults. Medications for opioid use disorder (MOUD) demonstrate the best evidence for treating OUD. Adherence to and retention in MOUD among adolescents and young adults, however, is incompletely understood. This systematic review examines the state of the literature regarding the association of age with adherence to and retention in MOUD using methadone, buprenorphine, or naltrexone among persons aged 10 to 24 along with related facilitators and barriers. The research team searched for all studies of MOUD that examined adherence, retention, or related concepts as an outcome variable where the sample included adolescents or young adults. Search criteria generated 10,229 records, which, after removing duplicates and conducting title/abstract screening, yielded 587 studies for full-text review. Ultimately, 52 articles met inclusion criteria for abstraction and 17 were selected for qualitative coding and analysis. This review found younger age to be consistently associated with shorter retention in the published literature, although the overall quality of included studies was low. Several factors at the individual, interpersonal, and institutional levels, such as concurrent substance use, MOUD adherence, family conflict, and MOUD dosage and flexibility, were seen as playing a role in MOUD retention among adolescents and young adults. This review highlights how MOUD providers can tailor treatment to increase retention of adolescents and young adults while pointing to the need for more research explaining MOUD adherence and retention disparities in this age group.

BACKGROUND: Opioid use disorder (OUD) is a global public health concern. The standard of care for OUD involves treatment using medications such as buprenorphine, methadone, or naltrexone. No known review exists to assess the contextual factors associated with medication for opioid use disorder (MOUD) in the Arab World. This systematic review serves as an implementation science study to address this research gap and improve the uptake of MOUD in the Arab World. METHODS: Systematic searches of Medline, PsycINFO, and EMBASE, and a citation analysis, were used to identify peer-reviewed articles with original data on MOUD in the Arab World. Quality assessment was conducted using the CASP appraisal tools, and main findings were extracted and coded according to the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. RESULTS: 652 research articles were identified, and 10 met inclusion criteria for final review. Four studies considered health-systems aspects of MOUD administration, such as cost-effectiveness, the motivations for and impact of national MOUD policies, the types of social, political, and scientific advocacy that led to the adoption of MOUD in Arab countries, and the challenges limiting its wide-scale adoption in the Arab World. Six papers considered MOUD at individual and group patient levels by evaluating patient quality of life, addiction severity, patient satisfaction, and patient perspectives on opioid agonist therapy. CONCLUSION: Despite financial and geographic barriers that limit access to MOUD in the Arab World, this review found MOUD to be cost-effective and associated with positive health outcomes for OUD patients in the Arab World. MOUD can be successfully established and scaled to the national level in the Arab context, and strong coalitions of health practitioners can lobby to establish MOUD programs in Arab countries. Still, the relative novelty of MOUD in this context precludes an abundance of research to address its long-term delivery in the Arab World.

HIV incidence continues to increase in Eastern Europe and Central Asia (EECA), in large part due to non-sterile injection drug use, especially within prisons. Therefore, medication-assisted therapy with opioid agonists is an evidence-based HIV-prevention strategy. The Kyrgyz Republic offers methadone within its prison system, but uptake remains low. Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a framework for identifying people who would potentially benefit from methadone, intervening to identify OUD as a problem and methadone as a potential solution, and providing referral to methadone treatment. Using an SBIRT framework, we screened for OUD in Kyrgyz prisons among people who were within six months of returning to the community (n = 1118). We enrolled 125 people with OUD in this study, 102 of whom were not already engaged in methadone treatment. We conducted a pre-release survey followed by a brief intervention (BI) to address barriers to methadone engagement. Follow-up surveys immediately after the intervention and at 1 month, 3 months, and 6 months after prison release assessed methadone attitudes and uptake. In-depth qualitative interviews with 12 participants explored factors influencing methadone utilization during and after incarceration. Nearly all participants indicated favorable attitudes toward methadone both before and after intervention in surveys; however, interest in initiating methadone treatment remained very low both before and after the BI. Qualitative findings identified five factors that negatively influence methadone uptake, despite expressed positive attitudes toward methadone: (1) interpersonal relationships, (2) interactions with the criminal justice system, (3) logistical concerns, (4) criminal subculture, and (5) health-related concerns.

Introduction Spain, which has one of the largest migrant populations in Europe, has committed to eliminating the hepatitis C virus (HCV). The aim of this study was to estimate the prevalence of HCV among migrant groups in Spain, a country of 46 million people, with an estimated HCV-antibody prevalence of 1.7%. Methods Studies on HCV and migration in Spain were identified by systematically searching three databases from the first records to 30 November 2017, and consulting experts at the Ministry of Health and in the 17 Spanish autonomous communities. A meta-analysis was conducted to determine pooled HCV prevalence for the general migrant population. Prevalences were also calculated for high-risk migrant populations and populations who had undergone hospital screening, stratified by region of origin. Results Out of 243 studies identified, 26 met the eligibility criteria. The meta-analysis of the general migrant population found HCV antibody prevalence to be 1.6%. Migrants originating from European countries, including those at high or moderate risk for HCV, had the highest pooled prevalence (7.1%). In the general migrant population, prevalence was highest among sub-Saharan African migrants (3.1%) and lowest among Latin American migrants (0.2%). Conclusion Based on the limited available data, the prevalence among the general migrant population was found to be the same as the general Spanish population. Further research is needed to more accurately determine HCV prevalence for the overall migrant population and specific migrant subpopulations with a higher risk in the country as a whole and in each of Spain's 17 autonomous communities.

BACKGROUND: Eastern Europe and Central Asia have intertwined HIV and incarceration epidemics, concentrated in people who inject drugs. Moldova is one of the few countries in this region that offers methadone within prisons, but uptake and post-release retention remains suboptimal. Screening, brief intervention, and referral to treatment (SBIRT) procedures are a potential implementation strategy to address this problem. METHODS: From June 1, 2017 to March 3, 2018, we conducted a 2-stage SBIRT strategy in nine prisons and four pre-trial detention facilities in Moldova among incarcerated persons with opioid use disorder (OUD; N = 121) and within 90 days of release. Survey results were analyzed to evaluate the effect of the SBIRT strategy on the uptake of and post-release retention on methadone maintenance treatment (MMT). RESULTS: Among the 121 screened with OUD, 27 were on MMT at baseline within the prison and this number increased to 41 after the two-step SBIRT intervention, reflecting a 51.9% increase over baseline. Eleven (78.6%) of the 14 participants that newly started MMT did so only after completing both SBIRT sessions. The brief intervention did not significantly improve knowledge about methadone but did improve attitudes towards it. Among the 41 participants who received methadone during this trial, 40 (97.6%) were retained 6 months after release; the one participant not retained was on methadone at the time of the intervention and had planned to taper off. CONCLUSION: The SBIRT strategy significantly improved participant attitudes, but treatment initiation mostly occurred after completing both sessions, including soon after release, but remained low overall. Work within the Moldovan prison subculture to dispel negative myths and misinformation is needed to further scale-up OAT in Moldova.

BACKGROUND: HIV incidence in Eastern Europe and Central Asia (EECA) continues to increase, primarily among people who inject drugs (PWID) and people in prisons. In Kyrgyzstan, an estimated 35% of people in prison are PWID, and 10% have been diagnosed with HIV. In 2008, Kyrgyzstan became the first country in EECA to provide free and voluntary methadone in prisons. We examine the impact of this national program on methadone within prison as well as linkage to and retention in treatment upon release to the community. METHODS: Administrative data from a national methadone registry with de-identified information were assessed retrospectively. We examined the delivery of methadone services, including the duration of treatment both within prison and after release, for all prisoners who were prescribed methadone in Kyrgyz prisons from 2008 to 2018. Reasons for discontinuing methadone, HIV status and methadone dose are also analyzed. RESULTS: Between 2008 and 2018, nine of Kyrgyzstan’s 16 prisons offered methadone, and 982 incarcerated people initiated methadone within prison. Prisoners prescribed methadone were mostly male (96.2%), in their mid-30s (mean=34.9 years), and had been incarcerated for a relatively long time (mean = 44.1 months); their mean treatment duration in prison was 12.5 months, and 31.6% had HIV. A subsample (N = 645; 65.7%) of these were released to the community. Of these 645 people, 356 (55.2%) were not taking methadone at the time of release, 128 (19.8%) were on methadone and continued it after release, and the remainder (N=161, 25.0%) were on methadone at the time of release, but subsequently discontinued it, most within the first 7 days after release Among those continuing methadone, 14.8% (N=19) remained on treatment ≥ 12 months. Independent correlates of linkage to methadone after release included positive HIV status (adjusted hazard ratio (aHR)=1.55; p = 0.033) receipt of methadone before their incarceration (aHR = 2.01; p = 0.039), and receipt of methadone at the time o release (aHR = 20.81; p < 0.001). CONCLUSION: This is the first evaluation of within-prison methadone treatment in EECA. Uptake of methadone within prison and retention in treatment after release were both low. Continuous maintenance of treatment throughout incarceration is an opportunity to optimize HIV prevention and link patients to methadone post-release.

Tajikistan is in a unique geopolitical location along the global heroin trade route, exacerbating its own opioid use disorder and HIV epidemics. With one of the highest rates of opioid use disorder in the world, and 20,000-30,000 people who inject drugs in the country, Tajikistan’s government and international actors have provided harm reduction measures for people who use drugs, like narcology centers, needle and syringe programs, and methadone maintenance therapy. No implementation science studies have been conducted in Tajikistan and the current implementation gaps in service uptake are unknown. The purpose of this paper is to determine the prevalence of harm reduction service uptake among people who use drugs in Tajikistan, and determine which factors are associated with service uptake. Methods This paper uses data from the National AIDS Registry, subset to patients who use drugs (n=11,029) and cross-sectional data from a bio-behavioral survey conducted in 2017 (n=2,390). Univariate and multivariate logistic regression were used to assess associations between study variables and probably of uptake of narcology center registration, uptake of needle and syringe programs, and registration into methadone maintenance therapy. Results Fewer than half of all people who inject drugs (42.4%) were registered with the narcology center , most people who inject drugs (88.6%) reported always having access to clean syringes, and only 5.3% of PWID had ever engaged in methadone treatment in Tajikistan. There were ethnic differences in service uptake – with ethnic Russians and Uzbeks less likely to use services than ethnic Tajiks. Men who have sex with men and people living with HIV were also more likely to access services than heterosexual or seronegative individuals. Conclusion Narcology center registration and clean needle coverage are high in Tajikistan. Methadone maintenance therapy uptake, however, is low, like in other countries in Eastern Europe and Central Asia. NGO and government initiatives that target risk groups (like LGBTQ+ people and people living with HIV) seem to have been somewhat effective at recruiting their clientele into services. Future research might focus on the “positive deviancy” of these subgroups of people who use drugs to learn how to increase service uptake generally.

BackgroundThe health sector’s effectiveness during a pandemic primarily depends on the availability, knowledge, skills, perceptions, and motivations of frontline healthcare workers. In this study, we aimed to investigate the contextual factors associated with the knowledge, perceptions, and the willingness of frontline healthcare workers to work during the COVID-19 pandemic in Nepal.MethodsA total of 1051 frontline health-workers from all seven Nepalese provinces were included in this web-based cross-sectional study, which was conducted in May 2020. Using a 5-point Likert scale questionnaire, we collected information on knowledge, perceptions, and the willingness of frontline healthcare workers to work during the COVID-19 pandemic. Multivariable logistic regression was applied to identify independent associations between predictors and outcome variables.ResultsOf the 1051 frontline health-workers, 17.2% were found to have inadequate knowledge on COVID-19, 63.6% reported unsatisfactory perceptions of government response, and 35.9% showed an unwillingness to work during the pandemic. Health workers at local health facilities (AOR: 0.35; 95% CI: 0.17-0.68) and those with chronic diseases were less likely to have adequate knowledge of COVID-19. Nurses (AOR: 2.10; 95% CI: 1.38-3.18), health-workers from Karnali Province (AOR: 2.62; 95% CI: 1.52-4.53), and those who had adequate knowledge of COVID-19 (AOR: 3.86; 95% CI: 2.51-6.16) were more likely to have satisfactory perception towards government response to COVID-19. In addition, laboratory-workers, health workers from Karnali province, and those with adequate knowledge (AOR: 1.81; 95% CI: 1.27-2.58) were more likely to work during the COVID-19 pandemic.ConclusionsWe concluded that frontline healthcare workers have some gaps in knowledge-related to COVID-19; about two-thirds of them had a negative perception of government response, and nearly one-third of them were unwilling to work. These observations demonstrate that prompt actions are required to improve health-worker knowledge of COVID-19, address negative perceptions to government responses, and motivate them to provide healthcare services during the pandemic.

Background Between 700 thousand and 1.2 million citizens of Tajikistan currently live in the Russian Federation, one of the only countries where the HIV epidemic continues to worsen. Given the previously reported barriers to healthcare access for migrants to the Russian Federation, and the rapidly expanding HIV epidemic in Eastern Europe and Central Asia, this present study set out to determine whether these barriers impact late presentation with HIV among Tajik migrants upon their return to Tajikistan. Method This study uses data from the Tajikistan Ministry of Health surveillance system (2006 – 2019). At time of diagnosis, patients are interviewed by staff of AIDS centers, and doctors complete routine intake forms and complete medical exam. Descriptive characteristics of HIV-positive migrant who had lived in the Russian Federation (n=503) were calculated and compared with those of HIV-positive non-migrants (n=9519). Missing data were imputed using a multiple imputation (predictive means matching, logistic regression imputation, and polytomous regression imputation). Two logistic models were created to model the probability of late presentation for HIV. The first model shows unadjusted associations between predictor variables and late presentation for HIV. The second model is shows multivariable associations between significant study variables identified in the univariate model, and late presentation. Results Compared to non-migrants, HIV-positive migrants are more likely to be from Gorno-Badakhshan region, are less likely to use illicit drugs, and are more likely to have purchased the services of sex workers.. The unadjusted logistic model found that for every year spent in the Russian Federation, the risk of late presentation for an HIV-positive Tajikistani migrant increases by 4.0% (95% CI: 0.3-7.7). The multivariate model showed that when age, sex, and region of origin are held constant, the risk of late presentation for an HIV-positive Tajikistani migrant increases by 4.0% (95% CI: 0.1-7.8) for each year spent in the Russian Federation. Conclusion The results of this paper suggest that if the Russian Federation were to loosen its restrictions of HIV care for foreign nationals, it might improve the treatment outcomes of migrant laborers. As this analysis is only correlational in nature, further research is needed to explicate the causal pathways of the associations found in the present analysis.

BackgroundHighly sensitive, non-invasive, and easily accessible diagnostics for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) are essential for the control of the Coronavirus Disease 2019 (COVID-19) pandemic. There is a clear need to establish a gold standard diagnostic for SARS-CoV-2 infection in humans using respiratory tract specimens.MethodsSearches will be conducted in the bibliographic databases Medline, Embase, bioRxiv, medRxiv, F1000, ChemRxiv, PeerJ Preprints, Preprints.org, Beilstein Archive, and Research Square. Relevant government documents and grey literature will be sought on the FDA’s Emergency Use Authorizations website, the ECDC’s website, and the website of the Foundation for Innovative New Diagnostics. Finally, papers categorized as diagnosis papers by the EPPI Centre’s COVID-19 living systematic map will be added to our screening process; those papers are tagged with the diagnosis topic based on human review, rather than database searches, and thus this set of papers might include ones that have not been captured by our search strategy.

Conclusion The results of this paper suggest that if the Russian Federation were to loosen its restrictions on HIV care for foreign nationals, it might improve the treatment outcomes of migrant laborers. As this analysis is only correlational in nature, further research is needed to explicate the causal pathways of the associations found in the present analysis.

IMPORTANCE: The ongoing overdose crisis continues to adversely affect adolescents and young adults (AYAs) and has led to numerous preventable deaths. Medications for opioid use disorder (MOUD), such as methadone, buprenorphine, and naltrexone, have the potential to reduce opioid use and associated harms; however, there are concerns that AYAs lack access to these potentially life-saving medications. OBJECTIVE: To systematically review peer-reviewed literature on MOUD access and associated factors to synthesize strategies that can improve MOUD access for AYAs who use opioids. EVIDENCE REVIEW: The MEDLINE, Embase, PsycINFO, CINAHL, Sociological Abstracts, Web of Science, and Global Dissertations & Theses databases were searched from database inception until May 3, 2021. English, French, Russian, or Spanish peer-reviewed studies that evaluated the availability, prescription receipt, or initiation of MOUD were eligible for inclusion. FINDINGS: This systematic review identified 37 cohort (n = 17), cross-sectional (n = 15), and qualitative (n = 5) studies that accounted for 179 785 AYAs (mean [SD] age, 24.4 [3.9] years; 148 779 [85%] were female; 67 771 [84%] were White) and examined access to methadone (30 studies), buprenorphine (26 studies), and naltrexone (10 studies). Findings reinforce concerns that AYAs were less likely to access MOUD and suggest that adolescents were more likely to receive naltrexone or buprenorphine-naloxone, which have a lower potential for abuse, in comparison with young adults. This review also identified other factors that were associated with MOUD access, including criminal justice involvement, residing in the US South, living in a limited-income area, Black race, and Hispanic or Latino ethnicity, suggesting ways in which treatment services may be improved to increase MOUD access and meet the treatment goals of AYAs. CONCLUSION AND RELEVANCE: This systematic review found gaps in MOUD access between AYAs and non-AYA populations in addition to differences in MOUD access between adolescents and young adults. Considering that existing clinical guidelines recommend the use of MOUD among AYAs, and in light of the increasing number of opioid toxicity deaths, there is a need to improve MOUD access among AYAs by reducing barriers to MOUD and providing AYAs with a continuum of health and social supports alongside MOUD. Future research into ways to encourage MOUD uptake among AYAs may improve the treatment and health outcomes for this population.

Background The Kyrgyz Republic (Kyrgyzstan) is one of few countries in Eastern Europe and Central Asia to provide methadone within its prisons, but uptake of this program has been suboptimal, in part because methadone uptake may have personal or social risks and consequences. Decision aids are evidence-based strategies that are designed to inform the patient's choice by objectively providing information that incorporates patient preferences. Methods We conducted qualitative interviews in Kyrgyz and Russian with currently and formerly incarcerated people (n = 36) in Kyrgyzstan from October 2016 to September 2018. Interviews explored factors influencing methadone utilization in prisons. Transcripts were coded by five researchers using content analysis. A secondary thematic analysis was conducted to determine factors specific to initiation or continuation of methadone treatment in prisons. Results We identified six interrelated themes affecting an individual's decision to initiate or continue methadone treatment: 1) informal prison governance (incarcerated people governing themselves); 2) informal prison economy; 3) perceived and objective benefits of methadone treatment; 4) perceived and objective side effects of methadone treatment; 5) distrust of formal prison administration (medical and correctional staff); and 6) desire for a “cure” from addiction. Conclusion Respondents’ perceptions about benefits, side effects, and addiction as a curable disease are not consistent with the available evidence. An evidence-based, informed decision-making aid would need to address the six themes identified here, of which several are specific to the Kyrgyz prison context. Unlike decision aids elsewhere, the unique aspects of incarceration itself alongside the informal governance system strongly present within Kyrgyz prisons will need to be incorporated into decisional processes to promote HIV prevention and treatment in a region with high rates of HIV transmission and mortality.

Between 800 thousand and 1.2 million citizens of Tajikistan currently live in the Russian Federation, one of the only countries where the HIV epidemic continues to worsen. Given the previously reported barriers to healthcare access for migrants in to the Russian Federation, and the rapidly expanding HIV epidemic in Eastern Europe and Central Asia, this present study set out to determine whether these barriers impact late presentation with HIV upon their return to Tajikistan. This study uses data from the Tajikistan Ministry of Health surveillance system. The dataset contains all new known HIV diagnoses between 2006 and 2018. At time of diagnosis, patients are interviewed by staff of AIDS centers, complete routine intake forms and complete medical exam and related forms by doctors. HIV-positive returned migrants who had lived in the Russian Federation (n = 770) were included in final data-analysis after data cleaning. Data were analyzed using three logistic (logit) models. The unadjusted logistic model found that for every year spent in the Russian Federation, the risk of late presentation for an HIV-positive Tajikistani migrant increases by 10.3% (95% CI: 5.5-15.3). The saturated multivariate model showed that when holding all study variables constant, the risk of late presentation for an HIV-positive Tajikistani migrant increases by 9.5% (95% CI: 2.6-16.9). The parsimonious multivariate model showed that when current age and region of origin are held constant, the risk of late presentation for an HIV-positive Tajikistani migrant increases by 6.3 (95% CI: 1.1-11.8). Even when other potential predictors are included in the logistic model, only age and length of time abroad remain statistically significant. The results of this paper suggest that if the Russian Federation were to adopt a reciprocal policy, it might improve treatment outcomes of migrant laborers. Further research is needed to explicate the causal pathways of the associations found in the present analysis. Key messages Structural factors are the strongest predictors of HIV late presentation among returned Tajik migrants to the Russian Federation. Further research is needed to explicate the causal pathways of the associations found in the present analysis.

Background: At the same time that advances in HIV prevention and treatment have changed the epidemic for gay and bisexual men, another epidemic faces this population. Gay and bisexual men represent one of the highest risk groups for depression, which potentially poses quality-of-life and public health challenges comparable to those of HIV. The present study seeks to inform comprehensive care for sexual minority men by estimating and comparing the morbidity of HIV and depression for US gay and bisexual men. Methods: Weighted counts of gay and bisexual men living with HIV and depression were derived from the CDC's Medical Monitoring Project and the National Survey on Drug Use and Health, respectively. Years lived with disability for HIV and depression come were calculated using the Global Burden of Disease Study's disability weights. Findings: Among gay and bisexual adult men in the US, the prevalence of past-year major depressive episodes is 14.17%, while the prevalence of HIV is 11.52%. We estimate that in calendar year 2015, major depressive episodes imposed 85,361 (95% CI: 58,293-112,212) years lived with disability among US adult gay and bisexual men, whereas HIV posed 42,981 (95% CI: 36,221-49,722) years lived with disability. Interpretation: This present analysis shows that depression morbidity currently exceeds that for HIV among US adult gay and bisexual men. While gay and bisexual men are frequently understood to be a high-risk population for HIV, including in guidelines for HIV prevention and treatment, the present analysis suggests that this population should also be considered at high-risk for depression. Healthcare providers should increasingly attend to the mental health needs of their gay and bisexual patients both within and outside of the context of HIV prevention and treatment.

High levels of drug dependence have been observed in the prison population globally, and the sharing of injecting drug equipment in prisons has contributed to higher prevalence of bloodborne diseases in prisoners than in the general population. Few prison needle and syringe programs (PNSPs) exist. We conducted a systematic review to assess evidence regarding health outcomes of PNSPs. We searched peer-reviewed databases for data relating to needle and syringe programs in prisons. The search methodology was conducted in accordance with accepted guidelines. Five studies met review inclusion criteria, and all presented evidence associating PNSPs with one or more health benefits, but the strength of the evidence was low. The outcomes for which the studies collectively demonstrated the strongest evidence were prevention of human immunodeficiency virus and viral hepatitis. Few negative consequences from PNSPs were observed, consistent with previous evidence assessments. More research is needed on PNSP effectiveness, and innovative study designs are needed to overcome methodological limitations of previous research. Until stronger evidence becomes available, policymakers are urged to recognize that not implementing PNSPs has the potential to cause considerable harm, in light of what is currently known about the risks and benefits of needle and syringe programs and PNSPs and about the high prevalence of human immunodeficiency virus and viral hepatitis in prisons.

Polycationic superparamagnetic nanoparticles (∼150-250 nm) were evaluated as virucidal agents. The particles possess a core-shell structure, with cores consisting of magnetite clusters and shells of functional silica covalently bound to poly(hexamethylene biguanide) (PHMBG), polyethyleneimine (PEI), or PEI terminated with aziridine moieties. Aziridine was conjugated to the PEI shell through cationic ring-opening polymerization. The nanometric core-shell particles functionalized with biguanide or aziridine moieties are able to bind and inactivate bacteriophage MS2, herpes simplex virus HSV-1, nonenveloped infectious pancreatic necrosis virus (IPNV), and enveloped viral hemorrhagic septicaemia virus (VHSV). The virus-particle complexes can be efficiently removed from the aqueous milieu by simple magnetocollection.

Background: In the context of the WHO’s 2016 Viral Hepatitis Strategy and the introduction of treatment that can cure more than 95% of cases with hepatitis C virus (HCV) infection, the European Joint Action on HIV and Co-infection Prevention and Harm Reduction (HA-REACT) undertook a study in the member states of the European Union (EU). It aimed to determine service providers’ understanding of the current services in their respective countries and the barriers experienced by PWID in accessing HCV testing, care and treatment services in their country. Methods: In 2017, 38 purposively selected harm reduction service providers completed a 26-item Englishlanguage online survey addressing the availability, accessibility and funding of HCV services at harm reduction centres. HCV-related data and reported findings were extracted by country or by responding organization. Results: Responses were received from all EU member states. Respondents from 23 countries reported that HCV tests are offered by harm reduction services in their countries, and eight countries reported that addiction specialists in their countries are able to prescribe HCV therapy. Almost half of the respondents (45%) said that their respective organizations had established referral systems with centres providing HCV treatment. Conclusions: Not all EU member states have harm reduction services that provide HCV tests, and many do not have established referral systems with treatment providers. Moreover, the inability of addiction specialists to prescribe HCV treatment points to missed opportunities to make treatment more accessible. Further, discrepancies were noted between the available HCV services and stakeholders’ knowledge about their availability.
