Abstract
Background Early identification of people living with hepatitis B virus infection is required to initiate treatment and care, prevent community transmission, and expand vaccination. However, only an estimated 10% of people living with chronic hepatitis B infection are diagnosed, and only 2% are on treatment globally. This study aimed to assess the prevalence of hepatitis B virus infection and its associated factors among high school students in Shinshicho Town, southern Ethiopia. Methods An institutional-based cross-sectional study was conducted among 380 high school students in Shinshicho Town, southern Ethiopia, from September to October 2022. A laboratory investigation of hepatitis B surface antigen was done to determine infection status. An odds ratio with a 95% confidence interval was used to declare statistical significance. Results The prevalence of hepatitis B virus infection among high school students in Shinshicho town was observed to be 7.6% (95% CI: 5.5, 10.5%). Age 20 to 24 years [AOR: 2.7; 95% CI: (1.0-7.0)], rural residence [AOR: 3.4; 95% CI: (1.3-8.9)], and history of unprotected drug injection [AOR: 11.3; 95% CI: (3.7-34.8)] were independently associated with hepatitis B virus infection. Conclusion A high prevalence of hepatitis B virus infection was observed among high school students in this study. Therefore, strengthening the school-based screen-and-treat program, especially targeting students from rural areas and young adults, and conducting awareness campaigns about the importance of practicing safe behaviors, such as avoiding unprotected drug injections, could contribute to the prevention and control of hepatitis B virus infection among high school students.

Abstract
OBJECTIVES Xylazine has emerged as a consistent part of the unregulated drug supply in recent months. We discuss major domains of xylazine's harm, current knowledge deficits, clinical and harm reduction strategies for minimizing harm, and xylazine's public health and policy context. As an interdisciplinary team from across the USA, we have pooled our knowledge to provide an overview of xylazine's current and emerging contexts. METHODS To inform this essay, the pertinent literature was reviewed, clinical knowledge and protocols were shared by multiple clinicians with direct expertise, and policy and public health context were added by expert authors. RESULTS We describe xylazine's major harm domains-acute poisoning, extended sedation, and wounds, along with anemia and hyperglycemia, which have been reported anecdotally but lack as clear of a connection to xylazine. Current successful practices for xylazine wound care are detailed. Understanding xylazine's epidemiology will also require greater investment in drug checking and surveillance. Finally, approaches to community-based wound care are discussed, along with an orientation to the larger policy and public health context. CONCLUSIONS Addressing the harms of xylazine requires interdisciplinary participation, investment in community-based harm reduction strategies, and improved drug supply surveillance. The relatively unique context of xylazine demands buy-in from public health professionals, harm reduction professionals, clinicians, basic science researchers, policymakers and more.

Abstract
Drug injection represents a major health problem in the US, with severe health consequences including the transmission of blood-borne infections. An examination of the most recent trends in drug injection is warranted by the fast-evolving drug epidemic and recent policy changes such as the federal funding ban on needle exchange programs. This research examines current drug injection trends, patterns, and socioeconomic and behavioral profiles of people who inject drugs (PWID). Data were derived from the 2002 to 2019 National Survey on Drug Use and Health (NSDUH). After examining the annual prevalence of drug injection since 2002, a latent class analysis was conducted to identify drug injection and other substance misuse patterns among PWID using the latest (2015-2019) NSDUH datasets. Associations between class membership and behavioral health comorbidities and treatment receipt were also assessed. The drug injection prevalence among US adults aged 18-64 increased from 0.21% in 2002/2004 to 0.36% in 2017/2019. Three distinctive groups were identified: the heroin injection group (45.2%), the methamphetamine injection group (28.0%), and the multi-drug injection group (26.8%). The methamphetamine injection group reported greater risks of experiencing serious psychological distress, suicidality, and limited substance use treatment. Special attention is needed for those who primarily injected methamphetamine. Programs to promote harm reduction and increase access to addiction treatment need to be expanded in at-risk communities while accounting for their distinct socioeconomic and drug use/misuse profiles.

Abstract
BACKGROUND The effectiveness of collaborative approaches in health interventions is underlined in the literature. Given the serious challenges to adequately managing the HCV epidemic in people who inject drugs (PWID), and the need to improve existing harm reduction (HR) interventions in this population, it seems important to investigate how collaboration between stakeholders is ensured in action research interventions. The present study aimed to explore interactions between outreach workers and research officers collaborating in the implementation of an action research project for PWID entitled OUTSIDER. METHODS Using three focus groups, we studied the views of 24 outreach workers involved in the implementation and evaluation of a harm reduction educational intervention to help PWID inject more safely in off-site settings. RESULTS The analysis of participants' discourses highlighted the mixed perceptions they had about OUTSIDER. Several limitations to collaboration emerged. Epistemological (theoretical vs. practical knowledge), methodological (science vs. intervention), axiological (standardised vs. adapted approach), and material (mobilised vs. available resources) issues all placed a burden on the outreach worker-research officer relationship. Outreach workers' acceptance of the project's intervention dimension but rejection of its scientific dimension highlights a lack of contractualisation between the stakeholders involved, and a more general problematisation of the role of outreach workers in implementing action research in HR. How collaboration was perceived and practised by outreach workers participating in OUTSIDER can be considered a reflection of the current challenges to implementing action research in HR. CONCLUSION This study of the interaction between the research and implementation dimensions of an action research project explored the tensions between different intervention stakeholders that must work together. Equitable participation and integration of the expertise, practices, and knowledge of all stakeholders involved is essential for successful action research. Given current HCV epidemiological challenges, new forms of cooperation are needed when developing healthcare services and when strengthening collaborative approaches.

Abstract
BACKGROUND We estimate the prevalence of drug injection, the variables associated with having ever injected and the proportion of ever injectors whose first drug injection was for having sex; we describe the first drug injection episode, analyze the drugs most frequently injected and estimate the prevalence of risky injecting behaviors. METHODS The participants were 3387 MSM without a previous HIV diagnosis attending four HIV/STI diagnosis services in Madrid and Barcelona. Lifetime prevalence and prevalence ratios (PRs) by different factors were calculated using Poisson regression models with robust variance. We compared the characteristics of first drug injection episode, lifetime injection and risky injecting behaviors of those whose first injection was for sex (FIS) with those whose was not (non-FIS). RESULTS Lifetime prevalence of injection was 2.1% (CI 1.7-2.7). In the multivariate analysis, it was strongly associated with having been penetrated by more than five men in the last 12 months (aPR = 10.4; CI 2.5-43.4) and having met most of their partners at private parties (aPR = 7.5; CI 4.5-12.3), and less strongly with other factors. Of those who had ever injected drugs, 81.9% injected for sex the first time they injected drugs (FIS). At first injection, FIS participants had a mean age of 31 years, 62.7% used mephedrone and 32.2% methamphetamine on that occasion. Of this FIS group 39.0% had ever shared drugs or equipment and 82.6% had always shared for sex. Some 30.8% of non-FIS reported having also injected drugs for sex later on. CONCLUSIONS Only two out of a hundred had ever injected, most to have sex and with frequent drug or injecting equipment sharing. Injecting for sex is the most common first episode of drug injection and is the most efficient risky behavior for the transmission of HIV, hepatitis B or C and other blood-borne infections. MSM participating in private parties should be considered a priority group for prevention policies.

Abstract
Stigma is a known barrier to treating substance use disorders and dramatically diminishes the quality of life of people who use drugs (PWUD) nonmedically. Stigma against PWUD may be especially pronounced in rural areas due to their decreased anonymity and residents' limited access, or resistance, to "neutralizing" information on factors associated with drug use. Stigma often manifests in the attitudes of professionals whom stigmatized individuals regularly interact with and often materially impact. We analyzed interviews conducted between July 2018 and February 2019 with professional stakeholders in rural southern Illinois who interact with PWUD, specifically those who use opioids nonmedically or who inject drugs (n = 30). We further analyzed interview data from a complementary PWUD sample (n = 22). Interviews addressed perspectives around nonmedical drug use and treatment/harm reduction, with analysis centered around the Framework Integrating Normative Influences on Stigma and its focus on micro, meso and macro level stigmatization processes. Stakeholder participants included professionals from local law enforcement, courts, healthcare organizations, emergency management services, and faith-based and social services organizations. Most stakeholders, particularly law enforcement, negatively perceived PWUD and nonmedical drug use in general, questioned the character, agency and extrinsic value of PWUD, and used labels (e.g. "addict," "abuser," etc.) that may be regarded as stigmatizing. Further, most respondents, including PWUD, characterized their communities as largely unaware or dismissive of the bio-medical and sociocultural explanations for opioid use, drug injection and towards harm reduction services (e.g., syringe exchanges) and naloxone, which were frequently framed as undeserved usages of taxpayer funds. In conclusion, rural stigma against PWUD manifested and was framed as a substantial issue, notably activating at micro, meso and macro levels. Stigma prevention efforts in these communities should aim to improve public knowledge on the intricate factors contributing to opioid use and drug injection and harm reduction programming's moral and fiscal value.

Abstract
BACKGROUND AND AIMS People who inject drugs (PWID) are a key population at high risk of hepatitis C virus (HCV) infection. The aim of this study was to delineate the epidemiology of HCV in PWID in the Middle East and North Africa (MENA). METHODS Syntheses of data were conducted on the standardized and systematically assembled databases of the MENA HCV Epidemiology Synthesis Project, 1989-2018. Random-effects meta-analyses and meta-regressions were performed. Meta-regression variables included country, study site, year of data collection and year of publication [to assess trends in HCV antibody prevalence over time], sample size and sampling methodology. Numbers of chronically infected PWID across MENA were estimated. The Shannon Diversity Index was calculated to assess genotype diversity. RESULTS Based on 118 HCV antibody prevalence measures, the pooled mean prevalence in PWID for all MENA was 49.3% [95% confidence interval (CI) = 44.4-54.1%]. The country-specific pooled mean ranged from 21.7% (95% CI = 4.9-38.6%) in Tunisia to 94.2% (95% CI = 90.8-96.7%) in Libya. An estimated 221 704 PWID were chronically infected, with the largest numbers found in Iran at 68 526 and in Pakistan at 46 554. There was no statistically significant evidence for a decline in HCV antibody prevalence over time. Genotype diversity was moderate (Shannon Diversity Index of 1.01 out of 1.95; 52.1%). The pooled mean percentage for each HCV genotype was highest in genotype 3 (42.7%) and in genotype 1 (35.9%). CONCLUSION Half of people who inject drugs in the Middle East and North Africa appear to have ever been infected with hepatitis C virus, but there are large variations in antibody prevalence among countries. In addition to > 200 000 chronically infected current people who inject drugs, there is an unknown number of people who no longer inject drugs who may have acquired hepatitis C virus during past injecting drug use. Harm reduction services must be expanded, and innovative strategies need to be employed to ensure accessibility to hepatitis C virus testing and treatment.

Abstract
BACKGROUND People who inject drugs often get bacterial infections. Few longitudinal studies have reported the incidence and treatment costs of these infections. METHODS For a cohort of 2335 people who inject heroin entering treatment for drug dependence between 2006 and 2017 in London, England, we reported the rates of hospitalisation or death with primary causes of cutaneous abscess, cellulitis, phlebitis, septicaemia, osteomyelitis, septic arthritis, endocarditis, or necrotising fasciitis. We compared these rates to the general population. We also used NHS reference costs to calculate the cost of admissions. RESULTS During a median of 8.0 years of follow-up, 24 % of patients (570/2335) had a severe bacterial infection, most commonly presenting with cutaneous abscesses or cellulitis. Bacterial infections accounted for 13 % of all hospital admissions. The rate was 73 per 1000 person-years (95 % CI 69-77); 50 times the general population, and the rate remained high throughout follow-up. The rate of severe bacterial infections for women was 1.50 (95 % CI 1.32-1.69) times the rate for men. The mean cost per admission was £4980, and we estimate that the annual cost of hospital treatment for people who inject heroin in London is £4.5 million. CONCLUSIONS People who inject heroin have extreme and long-term risk of severe bacterial infections.

Abstract
BACKGROUND In the last decade, European cities saw the development of "slamming," a practice related to chemsex that combines three elements: a sexual context, psychostimulant drug use, and injection practices. Epidemiological data on this practice is still sparse and media attention might have unintentionally distorted the size of this phenomenon. Therefore, we aimed to estimate the prevalence of men practicing slam and to identify factors associated with this practice. METHODS We used data from the Prevagay 2015 bio-behavioral survey to estimate the prevalence of slamming practices. A time-location sampling was performed among gay-labeled venues in five French cites. Behavioral information was recorded using a self-administered questionnaire. The HIV and HCV serostatus were investigated using ELISA tests on dried blood spots. The factors associated with slamming were assessed using a multiple logistic regression. We applied a weighting mechanism to enhance the generalizability of the estimates. RESULTS Among the 2646 men who have sex with men (MSM) included in our study, 3.1% reported slamming at least once during their lifetime (95% confidence interval (CI) = 2.2-4.3) and 1.6% (95% CI = 1-2.3) said they participated in a slamming session in the last 12 months. In the multivariate analysis, both HCV and HIV biological status were strongly associated with practicing "slam" in the last 12 months (OR = 13.37 (95% CI = 3.26-54.81) and 4.73 (95% CI = 1.58-14.44), respectively). Furthermore, a ten-point decrease in mental health scores was linked with the practice with an OR of 1.37 (95% CI = 1.08-1.73), indicating poorer mental health. CONCLUSION Even though slamming seems to involve a relatively small proportion of MSM, the vulnerability of this sub-group is high enough to justify setting up harm reduction measures and specific care. Training health professionals and creating services combining sexual health and drug dependence could be an effective response.

Abstract
BACKGROUND Drug injection has been increasing over the past decades all over the world. Hepatitis B and C viruses (HBV and HCV) are two common infections among people who inject drugs (PWID) and more than 60% of new human immunodeficiency virus (HIV) cases are PWID. Thus, investigating risk factors associated with drug use transition to injection is essential and was the aim of this research. METHODS We used a database from drug use treatment centers in Kermanshah Province (Iran) in 2013 that included 2098 records of people who use drugs (PWUD). The information of 29 potential risk factors that are commonly used in the literature on drug use was selected. We employed four classification methods (decision tree, neural network, support vector machine, and logistic regression) to determine factors affecting the decision of PWUD to transition to injection. RESULTS The average specificity of all models was over 84%. Support vector machine produced the highest specificity (0.9). Also, this model showed the highest total accuracy (0.91), sensitivity (0.94), positive likelihood ratio [1] and Kappa (0.94) and the smallest negative likelihood ratio (0). Therefore, important factors according to the support vector machine model were used for further interpretation. CONCLUSIONS Based on the support vector machine model, the use of heroin, cocaine, and hallucinogens were identified as the three most important factors associated with drug use transition injection. The results further indicated that PWUD with the history of prison or using drug due to curiosity and unemployment are at higher risks. Unemployment and unreliable sources of income were other suggested factors of transition in this research.

Abstract
PURPOSE OF REVIEW Scaling up evidence-based HIV prevention strategies like opioid agonist therapies (OAT), syringe services programs (SSPs), and antiretroviral therapy (ART) to mitigate the harms of drug injection is crucial within Eastern Europe and Central Asia (EECA), the only region globally where HIV incidence and mortality are increasing. RECENT FINDINGS Though the proportion of new HIV cases directly attributable to drug injection has recently declined, it remains a critical driver of HIV, especially to sexual partners. Concurrently, scale-up of OAT, SSPs, and ART has remained low, contributing to a volatile HIV epidemic among people who inject drugs (PWID). Despite evidence that drug injection contributes to an evolving HIV epidemic in EECA, coverage of evidence-based harm reduction programs remains substantially below needed targets. Due to a combination of punitive drug laws, ideological resistance to OAT among clinicians and policymakers, and inadequate domestic and international funding, limited progress has been observed in increasing the availability of these programs.

Abstract
BACKGROUND Transmitting blood-borne diseases is alarming in places with high prevalence of people who inject drugs. This study aimed to determine the prevalence of drug injection and its related predictors among prisoners with a history of tattooing in Iran. STUDY DESIGN Cross-sectional study. METHODS By using a census sampling, 5493 prisoners with a history of tattooing of 11988 prisoners participated for hepatitis B and C bio-behavioral surveillance surveys (BSS) in prisons of Iran, during 2015-2016 from 55 prisons in 19 provinces were assessed. The data for the BSS were collected using face-to-face checklist-based interviews. Weighted prevalence and the association between variables and history of drug injection were determined using Chi-square test and adjusted odds ratio (AOR) was estimated through multivariate logistic regression test using survey package. RESULTS The mean age of participants was 33.9 ±8.3 yr. Most of them were male (96.4%) and had a history of drug use (85.4%). The prevalence of drug injection among drug users was 20.2%, of which 33.9% had a history of shared injection. The prevalence of drug injection among prisoners with a history of tattooing is associated with male gender (P=0.047), age ≥35 yr (P<0.001), being single (P=0.002), being divorced/widow (P=0.039), and a history of imprisonment (P<0.001). CONCLUSION The prevalence of drug injection increases in the presence of other high-risk behaviors. It is necessary to initiate harm reduction programs and preventive interventions in groups with multiple high-risk behaviors.

Abstract
BACKGROUND Colombia has a growing population of young people who inject drugs (PWID). Despite the previously reported association of injection drug use with hepatitis c virus (HCV) in other countries, studies on HCV prevalence in PWID in Colombia are lacking. The objective of this study is to determine the prevalence, demographics, and correlations of risky injection behaviours in HCV seropositive PWID in four Colombian cities (Armenia, Bogotá, Cúcuta and Pereira). METHODS This was a cross-sectional study carried out between January and June of 2014 that included 918 PWID from four Colombian cities, recruited by Respondent Driven Sampling. A survey was administered to each participant, and blood samples were collected. Binary logistic regression and multivariate analyses for each city were conducted. RESULTS Average participant age was 26 years (SD 6.5). Of all participants, 27.3% of PWID were HCV seropositive, of which 52% were 25 years old or younger. In Pereira, increased risk of HCV infection was found for PWID that: had a history of injection drug use of 5 years or more (AOR: 3.0, CI: 1.7-7.8); were between 25 and 28 years of age (AOR: 5.2, CI: 1.0-26.3); had higher injection frequency (AOR: 2.5, CI: 1.4-4.2), and daily use of gifted, sold, or rented needles or syringes (AOR: 4.5, CI: 1.0-7.1). Additionally, in Cucuta, being HIV seropositive appeared to be greatly associated with risk of HCV seropositivity (AOR: 16.9, CI: 3.5-81.5). CONCLUSION Although prevalence of HCV in PWID in Colombia is lower than that reported for other countries, the described demographic characteristics and diverse risky injection behaviors on each city, in the context of a young PWID population with a short injection drug use history, should be taken into account in order to guide efforts towards preventing and reducing risk of HCV infection in PWID in Colombia.

Abstract
Recently, the multi-needle drug injection has been adopted to overcome the shortcomes of conventional single-needle injection, enhancing the efficiency of drug delivery. However, the effect of needle array on the efficacy of drug delivery has not been fully elucidated. In this study, the interactions of drug analogous solution injected from a pair of needles were analyzed to examine the design criteria of effective multi-needle devices for drug delivery. Temporal and spatial variations of relative contents of the solution in the tissues were compared according to the distance between two adjacent needles (DN). As the DN increases from 5 to 20 D, where D is the needle diameter, the solution from each needle encounters 3.5 times faster, and 4.22 times more solution was accumulated. At the same time, the effective spreading area was continuously increased from 54.2 to 177.8 mm2 and RCS gradient decreases from 0.087 to 0.037, due to the overlapping effect of the spreading solution from neighboring needles. Finally, based on the experimental results, an optimal design criterion of needle array for effective drug delivery was proposed. The present results would be helpful in the design of multi-needle injection devices and eventually offer advantage to patients with effective drug delivery.

Abstract
AIMS In France, a non-negligible proportion of opioid-dependent individuals inject morphine sulfate. Although it has not yet been officially approved as an opioid substitution treatment (OST), some physicians can prescribe its use for people in methadone or buprenorphine treatment failure. Longitudinal data from the ANRS-AERLI study, which evaluated an educational intervention for safer injection called AERLI, provided us the opportunity to better characterize the profile, risk practices and needs of people who inject morphine sulfate (MSI), through comparison with other injectors, and to identify correlates of HIV/HCV risk practices in this group. METHODS The national multisite ANRS-AERLI study assessed the impact of AERLI offered in volunteer harm reduction (HR) centers ("with intervention") (n = 113) through comparison with standard HR centers ("without intervention") (n = 127). All participants were scheduled to be followed up for 12 months and have 3 telephone interviews: at baseline, 6 months and 12 months. We compared MSI (n = 79) with other opioid injectors (n = 161) and then used a mixed logistic model to identify factors associated with HIV/HCV risk practices among MSI. FINDINGS Of the 240 eligible participants, 79 were regular MSI. They were less likely to use cocaine, crack or buprenorphine and to receive OST than other participants. Conversely, MSI were more likely to inject drugs more than three times a day and to report HIV/HCV risk practices. Among MSI, multivariate analysis showed that those receiving morphine sulfate as an OST were less likely to report such practices than other participants (aOR [95%CI] = 0.11 [0.02-0.61]). CONCLUSION Our results show that while MSI use fewer stimulants, they have more HIV/HCV risk practices than other injectors. However, when MSI are prescribed morphine sulfate as a treatment, these practices tend to decrease. Our findings suggest the importance of increasing access to morphine sulfate as a new OST in France.

Abstract
BACKGROUND Hepatitis C virus (HCV) remains a major contributor to morbidity and mortality worldwide. Since 2009, Kentucky has led the United States in cases of acute HCV, driven largely by injection drug use in rural areas. Improved treatment regimens hold promise of mitigating the impact and transmission of HCV, but numerous barriers obstruct people who inject drugs (PWID) from receiving care, particularly in medically underserved settings. METHODS 503 rural people who use drugs were recruited using respondent-driven sampling and received HCV screening and post-test counseling. Presence of HCV antibodies was assessed using enzyme immunoassay of dried blood samples. Sociodemographic and behavioral data were collected using computer-based questionnaires. Predictors of contacting a healthcare provider for follow-up following HCV-positive serotest and counseling were determined using discrete-time survival analysis. RESULTS 150 (59%) of 254 participants reported contacting a healthcare provider within 18 months of positive serotest and counseling; the highest probability occurred within six months of serotesting. 35 participants (14%) reported they were seeking treatment, and 21 (8%) reported receiving treatment. In multivariate time-dependent modeling, health insurance, internet access, prior substance use treatment, meeting DSM-IV criteria for generalized anxiety disorder, and recent marijuana use increased the odds of making contact for follow-up. Participants meeting criteria for major depressive disorder and reporting prior methadone use, whether legal or illegal, were less likely to contact a provider. CONCLUSION While only 8% received treatment after HCV-positive screening, contacting a healthcare provider was frequent in this sample of rural PWID, suggesting that the major barriers to care are likely further downstream. These findings offer insight into the determinants of engaging the cascade of medical treatment for HCV and ultimately, treatment-as-prevention. Further study and increased resources to support integrated interventions with effectiveness in other settings are recommended to mitigate the impact of HCV in this resource-deprived setting.

Abstract
BACKGROUND Coverage with opioid agonist treatments (OAT) that include methadone and buprenorphine is low (N=8400, 2.7%) for the 310,000 people who inject drugs (PWID) in Ukraine. In the context of widespread negative attitudes toward OAT in the region, patient-level interventions targeting the barriers and willingness to initiate OAT are urgently needed. METHODS A sample of 1179 PWID with opioid use disorder not currently on OAT from five regions in Ukraine was assessed using multivariable logistic regression for independent factors related to willingness to initiate OAT, stratified by their past OAT experience. RESULTS Overall, 421 (36%) PWID were willing to initiate OAT. Significant adjusted odds ratios (aOR) for covariates associated with the willingness to initiate OAT common for both groups included: higher injection frequency (previously on OAT: aOR=2.7; never on OAT: aOR=1.8), social and family support (previously on OAT: aOR=2.0; never on OAT: aOR=2.0), and positive attitude towards OAT (previously on OAT: aOR=1.3; never on OAT: aOR=1.4). Among participants previously on OAT, significant correlates also included: HIV-negative status (aOR=2.6) and depression (aOR=2.7). Among participants never on OAT, however, living in Kyiv (aOR=4.8) or Lviv (aOR=2.7), previous imprisonment (aOR=1.5), registration at a Narcology service (aOR=1.5) and recent overdose (aOR=2.6) were significantly correlated with willingness to initiate OAT. CONCLUSIONS These findings emphasize the need for developing interventions aimed to eliminate existing negative preconceptions regarding OAT among PWID with opioid use disorder in Ukraine, which should be tailored to meet the needs of specific characteristics of PWID in geographically distinct setting based upon injection frequency, prior incarceration, and psychiatric and HIV status.

Abstract
Objectives To evaluate the in vivo efficacy of 915 MHz percutaneous coagulation in the treatment of hepatic artery injury. Methods After inducing hepatic artery injury, 8 dogs in each group underwent 915 MHz microwave percutaneous coagulation therapy and 8 dogs were injected with batroxobin and α-cyanoacrylate. Results The hemostatic effects of 915 MHz microwave were better than drug injection, and the amount of bleeding was significantly lower (p < 0.05). Pathological examination showed that vessel wall necrosis were greater. Conclusion Contrast ultrasound guided 915 MHz microwave percutaneous coagulation treatment has potent hemostatic effects in the repair of in vivo hepatic artery injury.

Abstract
BACKGROUND Hepatitis C virus (HCV) is common among people who inject drugs (PWID) on methadoneprogram in Iran (Persia). However, a few PWID on methadone program report willingness to receive HCVtreatment. This study aimed to assess the factors which were associated with willingness to receive HCVtreatment in a group of PWID on methadone program in Iran. METHODS We surveyed 187 PWID at seven drops in centers in Tehran, Iran. Details of demographiccharacteristics, drug use, injection, HCV, and drug treatment history were collected using a 25-itemquestionnaire. Participants were serologically tested for the current status of HCV. FINDINGS The study found that 28.3% of the participants were HCV seropositive. In total, 49.1% of theparticipants reported unwillingness to receive HCV treatment. Awareness of current HCV status [odds ratio(OR) = 3.43; 95% confidence interval (CI): 1.33-7.26; P < 0.050]; adequate knowledge of HCV treatmentcenters in the community (OR = 3.9; 95% CI: 1.24-5.38; P < 0.050); participation in an educational programon HCV (OR = 2.9; 95% CI: 2.33-8.56; P < 0.001) and recent participation in the meetings of self-helpgroups (OR = 4.6; 95% CI: 3.43-9.33; P < 0.001) were significantly associated with current willingness toreceive HCV treatment. CONCLUSION The study results indicate that awareness of HCV status and the provision of adequate HCVeducation via different information centers can be associated with an increased willingness for HCVtreatment among PWID on methadone program. Conducting more research is suggested to assess theefficacy of educational programs and self-help groups in facilitating HCV treatment among PWID onmethadone program.

Abstract
AIM We tested the efficacy of a brief intervention based on motivational interviewing (MI) to reduce high-risk injection behaviours over a 6-month period among people who inject drugs (PWID). DESIGN A single-site two-group parallel randomized controlled trial comparing MI with a brief educational intervention (EI). SETTING A study office located in downtown Montréal, Canada, close to the community-based harm reduction programmes where PWID were recruited. PARTICIPANTS PWID who had shared drug injection equipment or shared drugs by backloading or frontloading in the month prior to recruitment were randomized to either the MI (112) or EI (109) groups. INTERVENTION The MI aimed to (1) encourage PWID to voice their desires, needs and reasons to change behaviours; (2) boost motivation to change behaviours; and (3) when the person was ready, support the plan he or she chose to reduce injection risk behaviours. The EI consisted of an individual session about safe injection behaviours. MEASUREMENTS The primary outcome was defined as having any of these risk behaviours at 6 months: having shared syringes, containers, filters or water to inject drugs in the previous month and backloading/frontloading; each behaviour was examined separately, as secondary outcomes. FINDINGS The probability of reporting a risk injection behaviour decreased in both the MI and the EI groups. At 6-month follow-up, participants who reported any risk behaviours were 50% [odds ratio (OR) = 0.50; confidence interval (CI) = 0.13-0.87] less likely to be in the MI group than in the EI group as well as those who reported sharing containers (OR = 0.50; CI = 0.09-0.90). PWID who reported sharing equipment excluding syringes were 53% less likely to be in the MI group (OR = 0.47; CI = 0.11-0.84). CONCLUSIONS A brief motivational interviewing intervention was more effective than a brief educational intervention in reducing some high risk injecting behaviours up in the subsequent 6 months.

Abstract
People who inject drugs (PWID) are central to the hepatitis C virus (HCV) epidemic. Opioid substitution treatment (OST) of opioid dependence has the potential to play a significant role in the public health response to HCV by serving as an HCV prevention intervention, by treating non-injection opioid dependent people who might otherwise transition to non-sterile drug injection, and by serving as a platform to engage HCV infected PWID in the HCV care continuum and link them to HCV treatment. This paper examines programmatic, structural and policy considerations for using OST as a platform to improve the HCV prevention and care continuum in 3 countries-the United States, Estonia and Viet Nam. In each country a range of interconnected factors affects the use OST as a component of HCV control. These factors include (1) that OST is not yet provided on the scale needed to adequately address illicit opioid dependence, (2) inconsistent use of OST as a platform for HCV services, (3) high costs of HCV treatment and health insurance policies that affect access to both OST and HCV treatment, and (4) the stigmatization of drug use. We see the following as important for controlling HCV transmission among PWID: (1) maintaining current HIV prevention efforts, (2) expanding efforts to reduce the stigmatization of drug use, (3) expanding use of OST as part of a coordinated public health approach to opioid dependence, HIV prevention, and HCV control efforts, (4) reductions in HCV treatment costs and expanded health system coverage to allow population level HCV treatment as prevention and OST as needed. The global expansion of OST and use of OST as a platform for HCV services should be feasible next steps in the public health response to the HCV epidemic, and is likely to be critical to efforts to eliminate or eradicate HCV.

Abstract
BACKGROUND In Indonesia, incarceration of people who inject drugs (PWID) and access to drugs in prison potentiate within-prison drug injection (WP-DI), a preventable and extremely high-risk behavior that may contribute substantially to HIV transmission in prison and communities to which prisoners are released. AIMS This mixed method study examined the prevalence, correlates, and social context of WP-DI among HIV-infected male prisoners in Indonesia. METHODS 102 randomly selected HIV-infected male prisoners completed semi-structured voice-recorded interviews about drug use changes after arrest, drug use cues within prison, and impact of WP-DI on HIV and addiction treatment. Logistic regression identified multivariate correlates of WP-DI and thematic analysis of interview transcripts used grounded-theory. RESULTS Over half (56%) of participants reported previous WP-DI. Of those, 93% shared injection equipment in prison, and 78.6% estimated sharing needles with ≥ 10 other prisoners. Multivariate analyses independently correlated WP-DI with being incarcerated for drug offenses (AOR = 3.29, 95%CI = 1.30-8.31, p = 0.011) and daily drug injection before arrest (AOR = 5.23, 95%CI = 1.42-19.25, p = 0.013). Drug availability and proximity to drug users while incarcerated were associated with frequent drug craving and escalating drug use risk behaviors after arrest. Energetic heroin marketing and stigmatizing attitudes toward methadone contribute to WP-DI and impede addiction and HIV treatment. CONCLUSIONS Frequent WP-DI and needle sharing among these HIV-infected Indonesian prison inmates indicate the need for structural interventions that reduce overcrowding, drug supply, and needle sharing, and improve detection and treatment of substance use disorders upon incarceration to minimize WP-DI and associated harm.

Abstract
BACKGROUND Prisoners, compared to the general population, are at greater risk of infection. Drug injection is the main route of human immunodeficiency virus ý(HIV) transmission, in particular in Iran. What would be of interest is to determine variables that govern drug injection among prisoners. However, one of the issues that challenge model building is incomplete national data sets. In this paper, we addressed the process of model development when missing data exist. METHODS Complete data on 2720 prisoners was available. A logistic regression model was fitted and served as gold standard. We then randomly omitted 20%, and 50% of data. Missing date were imputed 10 times, applying multiple imputation by chained equations (MICE). Rubin's rule (RR) was applied to select candidate variables and to combine the results across imputed data sets. In S1, S2, and S3 methods, variables retained significant in one, five, and ten imputed data sets and were candidate for the multifactorial model. Two weighting approaches were also applied. FINDINGS Age of onset of drug use, recent use of drug before imprisonment, being single, and length of imprisonment were significantly associated with drug injection among prisoners. All variable selection schemes were able to detect significance of these variables. CONCLUSION We have seen that the performances of easier variable selection methods were comparable with RR. This indicates that the screening step can be used to select candidate variables for the multifactorial model.

Abstract
BACKGROUND The present study compares the efficacy of 915- and 2450-MHz contrast-enhanced ultrasound (CEUS)-guided percutaneous microwave coagulation with that of CEUS-guided thrombin injection for the treatment of trauma-induced spleen hemorrhage. MATERIALS AND METHODS In a canine splenic artery hemorrhage model with two levels of arterial diameter (A, <1 mm and B, between 1 and 2 mm), hemostatic therapy was performed using 915- and 2450-MHz microwaves and drug injection. Therapy efficacy was measured by comparing bleeding rate, hemostatic time, bleeding index, bleeding volume, and pathology. RESULTS The most efficient technique was CEUS-guided 915-MHz percutaneous microwave coagulation therapy in terms of action time and total blood loss. The success rate of the 915-MHz microwave group was higher than that of the 2450-MHz microwave and the drug injection groups (except A level, P < 0.05). Hemostatic time, bleeding index, and bleeding volume were significantly less in the 915-MHz microwave group than those in the 2450-MHz microwave and drug injection groups (P < 0.05). Obvious degeneration and necrosis of parenchyma and large intravascular thrombosis were observed in the cavity of larger vessels in the 915-MHz microwave group, but pathologic changes of light injury could be seen in the other groups. CONCLUSIONS The present study provides evidence that microwave coagulation therapy is more efficient than thrombin injection for the treatment of splenic hemorrhage. Furthermore, treatment with 915-MHz microwaves stops bleeding more rapidly and generates a wider cauterization zone than does treatment with 2450-MHz microwaves.
