Abstract
Background People who inject drugs (PWID) are a priority population in HCV elimination programming. Overcoming sex and gender disparities in HCV risk, prevention, and the cascade of care is likely to be important to achieving this goal, but these have not yet been comprehensively reviewed. Methods Systematic review and meta-analysis. We searched Pubmed, EMBASE and the Cochrane Database of Systematic Reviews 1 January 2012-22 January 2024 for studies of any design reporting sex or gender differences among PWID in at least one of: sharing of needles and/or syringes, incarceration history, injection while incarcerated, participation in opioid agonist treatment or needle and syringe programs, HCV testing, spontaneous HCV clearance, direct-acting antiviral (DAA) treatment initiation or completion, and sustained virological response (SVR). Assessment of study quality was based on selected aspects of study design. Additional data were requested from study authors. Data were extracted in duplicate and meta-analysed using random effects models. PROSPERO registration CRD42022342806. Findings 9533 studies were identified and 92 studies were included. Compared to men, women were at greater risk for receptive needle and syringe sharing (past 6-12 months: risk ratio (RR) 1.12; 95% confidence interval (CI) 1.01-1.23; <6 months: RR 1.38; 95% CI 1.09-1.76), less likely to be incarcerated (lifetime RR 0.64; 95% CI 0.57-0.73) more likely to be tested for HCV infection (lifetime RR 1.07; 95% CI 1.01, 1.14), more likely to spontaneously clear infection (RR1.58; 95% CI 1.40-1.79), less likely to initiate DAA treatment (0.84; 95% CI 0.78-0.90), and more likely to attain SVR after completing DAA treatment (RR 1.02; 95% CI 1.01-1.04). Interpretation There are important differences in HCV risk and cascade of care indicators among people who inject drugs that may impact the effectiveness of prevention and treatment programming. Developing and assessing the effectiveness of gender-specific and gender-responsive HCV interventions should be a priority in elimination programming. Funding Réseau SIDA-MI du Québec.

Abstract
INTRODUCTION Understanding needle/syringe sharing is crucial for reducing hepatitis C virus (HCV) infection and reinfection. This study aimed to assess the prevalence and factors associated with needle/syringe sharing among people who inject drugs in Australia, including those previously receiving HCV treatment. METHODS The ETHOS Engage study was an observational cohort study which collected self-reported survey data on demographic and drug use information from people who inject drugs attending drug treatment clinics and needle and syringe programs over two waves between May 2018 and June 2021. Logistic regression was used to identify factors associated with needle/syringe sharing. RESULTS Overall, 1555/2395 people enrolled in ETHOS Engage (65%) injected drugs in the past month. Among these, 432 (28%) reported needle/syringe sharing in the past month and 276 (18%) reported receptive sharing. Factors associated with receptive sharing included younger age (adjusted odds ratio [aOR] 1.72; 95% confidence interval [CI] 1.28-2.30), recent incarceration (aOR 2.04; 95% CI 1.40-2.94), more frequent injecting (≥daily vs. less than weekly; aOR 2.59; 95% CI 1.75-3.84) and unstable housing (aOR 1.78; 95% CI 1.26-2.52). Among 560 participants with prior HCV treatment, 87 (16%) reported receptive sharing with younger age (aOR 2.42; 95% CI 1.45-4.05) and daily or greater injection frequency (aOR 2.51; 95% CI 1.31-4.83) associated with receptive sharing. DISCUSSION AND CONCLUSIONS Needle/syringe sharing was common among this population accessing harm reduction services. This study identifies high-risk populations with needle/syringe sharing. Research is needed to optimise HCV treatment to ensure people with ongoing risk behaviours receive adequate harm reduction following treatment to prevent reinfection.

Abstract
BACKGROUND Evaluating gender-specific trends in hepatitis C virus (HCV) treatment uptake among men and women who inject drugs is crucial for ensuring equitable progress towards HCV elimination. This study aimed to quantify differences in testing, treatment, and current HCV infection between men and women who inject drugs. METHOD ETHOS Engage is an observational cohort study of people who inject drugs attending drug treatment clinics and needle and syringe programs in Australia recruited from May 2018-September 2019 (wave 1) and November 2019-April 2021 (wave 2). Participants completed a questionnaire including self-reported HCV testing and treatment history and underwent point-of-care HCV RNA testing (Xpert® HCV Viral Load Fingerstick). Logistic regression was used to compare the factors associated with self-reported HCV testing and treatment and current HCV infection for men and women who inject drugs. RESULTS Among 2,395 participants enrolled in ETHOS Engage, 66% (n = 1,591) were men, 33% (n = 786) women, and <1% (n = 18) did not identify as a man or woman. HCV testing history and current infection were similar among men and women. Among men or women ever eligible for HCV treatment (ever chronic HCV) (n = 1,242), women were less likely to report a history of HCV treatment compared to men (227/352, 64% vs. 631/890, 71%; p = 0.03). Among women, those aged <45 were less likely to report HCV testing (aOR: 0.57, 95%CI: 0.36, 0.90), treatment (aOR: 0.47, 95%CI: 0.29, 0.77), and more likely to have HCV infection (aOR: 1.48, 95%CI: 1.00, 2.20) CONCLUSION: Among women, those of childbearing age (<45) were less likely to report testing and treatment and were more likely to have current HCV infection. Women <45 years old should be a priority population for HCV care. Services that interface with these women should be optimised to enhance HCV testing and treatment.

Abstract
Abstract In 2023, an increased number of urogenital and anorectal infections with Neisseria meningitis serogroup Y (MenY) were reported in New South Wales (NSW). Whole genome sequencing (WGS) found a common sequence type (ST-1466), with limited sequence diversity. Confirmed outbreak cases were NSW residents with a N. meningitidis isolate matching the cluster sequence type; probable cases were NSW residents with MenY isolated from a urogenital or anorectal site from 1 July 2023 without WGS testing. Of the 41 cases, most were men (n = 27), of whom six reported recent contact with a female sex worker. Five cases were men who have sex with men and two were female sex workers. Laboratory alerts regarding the outbreak were sent to all Australian jurisdictions through the laboratories in the National Neisseria Network. Two additional states identified urogenital MenY ST-1466 infections detected in late 2023. Genomic analysis showed all MenY ST-1466 sequences were interspersed, suggestive of an Australia-wide outbreak. The incidence of these infections remains unknown, due to varied testing and reporting practices both within and across jurisdictions. Isolates causing invasive meningococcal disease (IMD) in Australia are typed, and there has been no MenY ST-1466 IMD recorded in Australia to end of March 2024. Concerns remain regarding the risk of IMD, given the similarity of these sequences with a MenY ST-1466 IMD strain causing a concurrent outbreak in the United States of America.

Abstract
BACKGROUND Chlamydia remains the most notified bacterial sexually transmissible infection in Australia with guidelines recommending testing for re-infection at 3months post treatment. This paper aimed to determine chlamydia retesting and repeat positivity rates within 2-4months among young women in Australia, and to evaluate what factors increase or decrease the likelihood of retesting. METHODS Chlamydia retesting rates among 16-29-year-old women were analysed from Australian Collaboration for Coordinated Enhanced Sentinel Surveillance of sexually transmissible infection and bloodborne virus (ACCESS) sentinel surveillance data (n =62 sites). Among women with at least one positive test between 1 January 2018 and 31 August 2022, retesting counts and proportions within 2-4months were calculated. Logistic regression was performed to assess factors associated with retesting within 2-4months. RESULTS Among 8758 women who were positive before 31 August 2022 to allow time for follow up, 1423 (16.2%) were retested within 2-4months, of whom 179 (12.6%) tested positive. The odds of retesting within 2-4months were 25% lower if tested in a coronavirus disease 2019 (COVID-9) pandemic year (2020-2022) (aOR=0.75; 95% CI 0.59-0.95). Among 9140 women with a positive test before 30 November 2022, 397 (4.3%) were retested too early (within 7days to 1month) and 81 (20.4%) of those were positive. CONCLUSIONS Chlamydia retesting rates remain low with around a sixth of women retested within 2-4months in line with guidelines. Re-infection is common with around one in eight retesting positive. An increase in retesting is required to reduce the risk of reproductive complications and onward transmission.

Abstract
OBJECTIVES There is limited research on health-related quality of life (HRQoL) among people who inject drugs (PWID). We evaluated the HRQoL and associated factors among a cohort of PWID in Australia. METHODS Participants were enrolled in an observational cohort study (the Enhancing Treatment of Hepatitis C in Opioid Substitution Settings Engage Study) from May 2018 to September 2019 (wave 1) and November 2019 to June 2021 (wave 2). Participants completed the EQ-5D-5L survey at enrolment. Two-part models were used to assess the association of clinical and socioeconomic characteristics with EQ-5D-5L scores. RESULTS Among 2395 participants (median age, 43 years; 66% male), 65% reported injecting drug use in the past month, 20% had current hepatitis C virus (HCV) infection, and 68% had no/mild liver fibrosis (F0/F1). Overall, the mean EQ-5D-5L and EQ-visual analog scale scores were 0.78 and 57, respectively. In adjusted analysis, factors associated with significantly lower EQ-5D-5L scores include older ages, female (marginal effect = -0.03, P = .014), being homeless (marginal effect = -0.04, P = .040), and polysubstance use (marginal effect = -0.05, P < .001). Factors associated with significantly higher EQ-5D-5L scores were being Aboriginal/Torres Strait Islander (marginal effect = 0.03, P = .021) and recent injecting drug use in the past 12 months. Current HCV infection and liver fibrosis stage were not associated with reduced HRQoL among the study participants. CONCLUSIONS PWID experienced a lower HRQoL compared with the general population. Further research is needed to understand HRQoL in this population to facilitate the development of multifaceted care models for PWID beyond HCV cure and inform health economic analyses for identifying optimal health strategies for PWID.

Abstract
BACKGROUND Dried blood spot (DBS) testing provides an alternative to phlebotomy and addresses barriers to accessing healthcare experienced by some key populations. Large-scale evaluations of DBS testing programs are needed to understand their feasibility. This study evaluated the implementation of a state-wide DBS HIV and hepatitis C virus (HCV) testing pilot. METHODS The New South Wales (NSW) DBS Pilot is an interventional cohort study of people testing for HIV antibody and/or HCV RNA from DBS samples in NSW, Australia. Participants at risk of HIV/HCV participated in testing via: 1) self-registration online with a DBS collection kit delivered and returned by conventional postal service; or 2) assisted DBS sample collection at 36 community health sites (including drug treatment and harm-minimisation services) and prisons. Participants received results by text (HIV antibody/ HCV RNA not detected) or a healthcare provider (HIV antibody/ HCV RNA detected). The RE-AIM framework was used to evaluate reach, effectiveness, adoption, and implementation. RESULTS Reach: Between November 2016 and December 2020, 7,392 individuals were tested for HIV and/or HCV (21% self-registration, 34% assisted in community, and 45% assisted in prison). EFFECTIVENESS Of 6,922 people tested for HIV (19% men who have sex with men, 13% living outside major cities, 21% born outside Australia), 51% (3,521/6,922) had no HIV test in the past two years, 0.1% (10/6,922) were newly diagnosed with HIV, and 80% (8/10) initiated HIV treatment within six months. Of 5,960 people tested for HCV (24% women, 35% Aboriginal and/or Torres Strait Islander, 55% recently injected drugs), 15% had detectable HCV RNA (878/5,960), and 45% (393/878) initiated treatment within six months. Adoption: By the end of 2020, DBS via assisted registration was available at 36 community sites and 21 prisons. IMPLEMENTATION 90% of DBS cards arriving at the laboratory had the three full spots required for testing; the proportion was higher in assisted (94%) compared to online (76%) registration. CONCLUSIONS This study demonstrated the feasibility of DBS testing for HIV and HCV in key populations including Aboriginal and Torres Strait Islander peoples, men who have sex with men, people who inject drugs, and demonstrated the utility of DBS in the prison setting.

Abstract
Background Dried blood spot (DBS) testing for hepatitis C virus (HCV) RNA provides a sampling option that avoids venepuncture and can be carried out in a nonclinical setting. Large-scale evaluations are needed to understand how DBS testing can reduce HCV burden. This study estimated prevalence of, and factors associated with, HCV RNA and treatment initiation among people enrolled in a state-wide pilot of people testing in the NSW DBS Pilot in New South Wales, Australia. Methods People at risk of HIV/HCV could participate via (1) self-registration online with a DBS collection kit delivered and returned by conventional postal service; or (2) assisted DBS sample collection at a community site or prison. Logistic regression was used to identify factors associated with detectable HCV RNA and treatment initiation within 6 months of testing. Results Between September 2017 and December 2020, 5960 people were tested for HCV (76% men, 35% Aboriginal and/or Torres Strait Islander, 55% recently injected drugs): 21% online self-registration, 34% assisted registration in the community, 45% assisted registration in prison. Fifteen percent had detectable HCV RNA (878/5960). Overall, 44% (n = 386/878) of people with current HCV initiated treatment within 6 months (13% online self-registration, 27% assisted registration in the community, 61% assisted registration in prison). Testing in prison compared with the community (adjusted odds ratio [aOR], 4.28; 95% CI, 3.04-6.03) was associated with increased odds of treatment initiation. Being a woman compared with a man (aOR, 0.68; 95% CI, 0.47-0.97) was associated with reduced treatment initiation. Conclusions The NSW DBS Pilot demonstrates the feasibility of using DBS to promote HCV testing and treatment in community and prison settings.

Abstract
INTRODUCTION Evaluating progress towards hepatitis C virus (HCV) elimination among Aboriginal and Torres Strait Islander peoples is critical given the disproportionate burden of infection. We examined factors associated with current HCV infection and self-reported treatment among Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal peoples) and non-Aboriginal peoples who inject drugs (PWID) in Australia. METHODS ETHOS Engage is an observational cohort study of PWID attending drug treatment and needle and syringe programs in Australia. Participants underwent point-of-care HCV RNA testing (Xpert HCV RNA Viral Load Fingerstick) and completed a questionnaire including self-reported history of HCV treatment. RESULTS Between May 2018 and June 2021, 2395 participants were enrolled and 555 (23%) identified as Aboriginal (median age 42 years, 58% were men, 63% injected drugs in last month, 76% ever incarcerated). HCV RNA prevalence was 23% among Aboriginal PWID (24% in 2018-2019 and 21% in 2019-2021; p = 0.44), and 21% among non-Aboriginal PWID (24% in 2018-2019 and 16% in 2019-2021; p < 0.001). Self-reported HCV treatment was 65% among Aboriginal PWID (63% in 2018-2019 and 69% in 2019-2021; p = 0.30), and 70% among non-Aboriginal PWID (67% in 2018-2019 and 75% in 2019-2021; p < 0.001). Among Aboriginal PWID, current HCV infection was associated with recently injecting drugs and receiving opioid agonist treatment, and self-reported HCV treatment was negatively associated with younger age, homelessness and recently injecting drugs. DISCUSSION AND CONCLUSIONS Equitable access to HCV care and prevention is needed to ensure Australia meets its elimination targets among Aboriginal PWID.

Abstract
OBJECTIVES People who inject drugs (PWID) are at a high risk of hepatitis C virus (HCV) infection. HCV cure is associated with improved patient-reported outcomes (PROs), but there are little data among PWID. This study aimed to assess the change in PROs during and after HCV direct-acting antiviral (DAA) treatment. METHODS This analysis used data from 2 clinical trials of DAA treatment in PWID. PROs assessed included health-related quality of life, social functioning, psychological distress, housing, and employment. Generalized estimating equations and group-based trajectory modeling were used to assess changes in PROs over time. RESULTS No significant changes in the 3-level version of EQ-5D scores, EQ visual analogue scale scores, social functioning, psychological distress, and housing were observed over the 108-week study period. There was a significant increase in the proportion of participants employed (18% [95% confidence interval (CI) 12%-23%] at baseline to 28% [95% CI 19%-36%] at the end of the study). Participants were more likely to be employed at 24 weeks and 108 weeks after commencing treatment. Having stable housing increased the odds of being employed (odds ratio 1.70; 95% CI 1.00-2.90). The group-based trajectory modeling demonstrated that most outcomes remained stable during and after DAA treatment. CONCLUSIONS Although no significant improvement was identified in health-related quality of life after HCV DAA treatment, there was a modest but significant increase in employment during study follow-up. The study findings support the need for multifaceted models of HCV care for PWID addressing a range of issues beyond HCV treatment to improve quality of life.

Abstract
We study the axisymmetric, wide gap, spherical Couette flow in the presence of noise in numerical simulations and experiments. Such studies are important because most of the flows in nature are subjected to random fluctuations. Noise is introduced into the flow by adding fluctuations to the inner sphere rotation which are random in time with zero mean. Flows of a viscous incompressible fluid are induced either by rotation of the inner sphere only or by the co-rotation of the spheres. Mean flow generation was found to occur under the action of additive noise. A higher relative amplification of meridional kinetic energy compared to the azimuthal component was also observed under certain conditions. Calculated flow velocities were validated by laser Doppler anemometer measurements. A model is proposed to elucidate the rapid growth of meridional kinetic energy for flows induced by varying the co-rotation of the spheres. Our linear stability analysis for flows induced by the rotation of the inner sphere revealed a decrease in the critical Reynolds number, corresponding to the onset of the first instability. Also, in this case, a local minimum of the mean flow generation on approaching the critical Reynolds number was observed, which is consistent with the available theoretical predictions. This article is part of the theme issue 'Taylor-Couette and related flows on the centennial of Taylor's seminal Philosophical Transactions paper (Part 2)'.

Abstract
OBJECTIVES To examine changes in the positive infectious syphilis test rate among women and heterosexual men in major Australian cities, and rate differences by social, biomedical, and behavioural determinants of health. DESIGN, SETTING Analysis of data extracted from de-identified patient records from 34 sexual health clinics participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance of Sexually Transmissible Infections and Blood Borne Viruses (ACCESS). PARTICIPANTS First tests during calendar year for women and heterosexual men aged 15 years or more in major cities who attended ACCESS sexual health clinics during 2011-2019. MAIN OUTCOME MEASURES Positive infectious syphilis test rate; change in annual positive test rate. RESULTS 180 of 52 221 tested women (0.34%) and 239 of 36 341 heterosexual men (0.66%) were diagnosed with infectious syphilis. The positive test rate for women was 1.8 (95% confidence interval [CI], 0.9-3.2) per 1000 tests in 2011, 3.0 (95% CI, 2.0-4.2) per 1000 tests in 2019 (change per year: rate ratio [RR], 1.12; 95% CI, 1.01-1.25); for heterosexual men it was 6.1 (95% CI, 3.8-9.2) per 1000 tests in 2011 and 7.6 (95% CI, 5.6-10) per 1000 tests in 2019 (RR, 1.10; 95% CI, 1.03-1.17). In multivariable analyses, the positive test rate was higher for women (adjusted RR [aRR], 1.85; 95% CI, 1.34-2.55) and heterosexual men (aRR, 2.39; 95% CI, 1.53-3.74) in areas of greatest socio-economic disadvantage than for those in areas of least socio-economic disadvantage. It was also higher for Indigenous women (aRR, 2.39; 95% CI, 1.22-4.70) and for women who reported recent injection drug use (aRR, 4.87; 95% CI, 2.18-10.9) than for other women; it was lower for bisexual than heterosexual women (aRR, 0.48; 95% CI, 0.29-0.81) and for women who reported recent sex work (aRR, 0.35; 95% CI, 0.29-0.44). The positive test rate was higher for heterosexual men aged 40-49 years (aRR, 2.11; 95% CI, 1.42-3.12) or more than 50 years (aRR, 2.36; 95% CI, 1.53-3.65) than for those aged 15-29 years. CONCLUSION The positive test rate among both urban women and heterosexual men tested was higher in 2019 than in 2011. People who attend reproductive health or alcohol and drug services should be routinely screened for syphilis.

Abstract
BACKGROUND Point-of-care hepatitis C virus (HCV) RNA testing can facilitate single-visit diagnosis and treatment. This study evaluated a single-visit test and treat intervention integrating point-of-care HCV RNA testing, linkage to nursing care, and peer-supported engagement/delivery of treatment among people with recent injecting drug use at a peer-led needle and syringe program (NSP). METHODS TEMPO Pilot is an interventional cohort study of people with recent injecting drug use (previous month) recruited between September 2019-February 2021 from one peer-led NSP in Sydney, Australia. Participants received point-of-care HCV RNA testing (Xpert HCV Viral Load Fingerstick), linkage to nursing care, and peer-supported engagement/delivery of treatment. The primary endpoint was the proportion initiating HCV therapy. RESULTS Among 101 people with recent injecting drug use (median age 43; 31% female), 27% (n = 27) were HCV RNA detectable. Treatment uptake was 74% (20 of 27; sofosbuvir/velpatasvir, n = 8; glecaprevir/pibrentasvir, n = 12). Among people initiating treatment (n = 20), 45% (n = 9) initiated treatment at the same visit, 50% (n = 10) in the next 1-2 days, and 5% on day 7 (n = 1). Two participants initiated treatment outside the study (overall treatment uptake 81%). Reasons for not initiating treatment included loss to follow-up (n = 2), no reimbursement (n = 1), not suitable for treatment (mental health) (n = 1), and inability to perform liver disease assessment (n = 1). In the full analysis set, 60% (12 of 20) completed treatment and 40% (8 of 20) had a sustained virological response (SVR). In the evaluable population (excluding people without an SVR test), SVR was 89% (8 of 9). CONCLUSION Point-of-care HCV RNA testing, linkage to nursing, and peer-supported engagement/delivery led to high HCV treatment uptake (majority single-visit) among people with recent injecting drug use attending a peer-led NSP. The lower proportion of people with SVR highlights the need for further interventions to support treatment completion.

Abstract
Aboriginal and Torres Strait Islander peoples experience a disproportionate burden of hepatitis C virus (HCV) infection. This study assessed the effectiveness of direct-acting antiviral (DAA) therapy among Aboriginal peoples in the three years following universal access in Australia. REACH-C, a national multicentre prospective cohort study, evaluated HCV treatment outcomes from sequential DAA initiations across 33 health services between March 2016 and June 2019. DAA effectiveness was assessed by sustained virological response (SVR) in the total (full analysis set) and effectiveness (modified analysis set excluding those lost to follow-up) populations. Overall, 915 (10%) Aboriginal and 8095 (90%) non-Indigenous people commenced DAA therapy, of whom 30% and 16% reported current injecting drug use and 73% and 42% were treated in primary care, respectively. SVR in the total and effectiveness populations was 74% and 94% among Aboriginal people and 82% and 94% among non-Indigenous people, with loss to follow-up contributing to lower SVR in the total population analysis (22% Aboriginal, 13% non-Indigenous). Among Aboriginal people, returning for follow-up was positively associated with older age (aOR 1.20; 95% CI 1.04, 1.39) and SVR was negatively associated with cirrhosis (aOR 0.39; 95% CI 0.19, 0.80) and prior DAA treatment (aOR 0.14; 95% CI 0.04, 0.49). Factors reflecting higher vulnerability or inequity were not associated with returning for testing or SVR. DAA therapy was highly effective among Aboriginal peoples with HCV treated through primary and tertiary services. Tailored community-led interventions are necessary to optimize follow-up and engagement. Sustained DAA uptake and equitable access to care, treatment and prevention are required for HCV elimination.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
BACKGROUND Awareness of hepatitis C virus (HCV) infection status among people who inject drugs (PWID) can empower people with diagnosis, enable treatment uptake, and facilitate elimination. We aimed to evaluate awareness of HCV infection status among a large national cohort of PWID in an era of unrestricted HCV treatment. METHODS ETHOS Engage is an observational cohort study of PWID attending drug treatment clinics and needle and syringe programs in Australia. Participants completed a questionnaire containing self-reported HCV data (including infection status: never tested, tested/unknown, no current HCV infection [HCV RNA not detectable], current HCV infection [HCV RNA detectable]) and underwent point-of-care HCV RNA testing (Xpert® HCV Viral Load Fingerstick). Awareness was defined as concordant self-reported HCV status and test result. Awareness was assessed among all participants, those with current HCV infection, and participants who reported a lifetime history of HCV treatment. Logistic regression was used to assess factors associated with awareness in these three populations. RESULTS Among 2,305 PWID, 65% (n=1,506) were aware of their HCV infection status (self-reported HCV status matched HCV point-of-care result). Awareness of infection status was higher among those who were not currently infected (70%, n=1,281/1,818) compared to those with current HCV infection (46%, n=225/487). After adjusting, those with current HCV infection were less likely to be aware of infection status (aOR: 0.40, 95%CI: 0.30, 0.45). Among those who reported a lifetime history of HCV treatment, 71% (n=592/829) were aware of their HCV infection status. CONCLUSION Among a large cohort of PWID in Australia, awareness of HCV infection status is sub-optimal, with particularly concerning levels among those with active infection. Increased and simplified testing, post-test counselling, and post-treatment monitoring is warranted.

Abstract
Background and Aims In moving towards the elimination of hepatitis C virus (HCV) infection among people living with HIV, understanding HCV transmission patterns may provide insights to guide and evaluate interventions. In this study, we evaluated patterns of, and factors associated with HCV phylogenetic clustering among people living with HIV/HCV co‐infection in Australia in the direct‐acting antiviral era. Methods HCV RNA was extracted from dried blood spot (DBS) samples collected between 2014 and 2018 in the CEASE cohort study. The HCV Core‐E2 region was amplified by a polymerase chain reaction and Sanger sequenced. Maximum likelihood phylogenetic trees (1000 bootstrap replicates) were used to identify patterns of clustering (3% genetic distance threshold). Mixed‐effects logistic regression was used to determine correlates of phylogenetic clustering. Factors assessed were sexual risk behavior, education, injecting drug use, housing, employment, HIV viral load, age, sex, and sexuality. Results Phylogenetic trees were reconstructed for HCV subtype 1a (n = 139) and 3a (n = 63) sequences, with 29% (58/202) in a pair or cluster. Overall (n = 202), phylogenetic clustering was positively associated with younger age (under 40; adjusted odds ratio [aOR] 2.52, 95% confidence interval [CI] 1.20–5.29), and among gay and bisexual men (n = 168), was positively associated with younger age (aOR 2.61, 95% CI 1.10–6.19), higher education (aOR 2.58, 95% CI 1.09–6.13), and reporting high‐risk sexual behavior (aOR 3.94, 95% CI 1.31–11.84). During follow‐up, five reinfections were observed, but none were in phylogenetic clusters. Conclusion This study found a high proportion of phylogenetic relatedness, predominantly among younger people and gay and bisexual men reporting high‐risk sexual behavior. Despite this, few reinfections were observed, and reinfections demonstrated little relationship with known clusters. These findings highlight the importance of rapid HCV treatment initiation, together with monitoring of the phylogeny.

Abstract
Virological failure occurs in a small proportion of people treated for hepatitis C virus (HCV) with direct-acting antiviral (DAA) therapies. This study assessed retreatment for virological failure in a large real-world cohort. REACH-C is an Australian observational study (n=10843) evaluating treatment outcomes of sequential DAA initiations across 33 health services between March 2016 to June 2019. Virological failure retreatment data were collected until October 2020. Of 408 people with virological failure (81% male; median age 53; 38% cirrhosis; 56% genotype 3), 213 (54%) were retreated once; 15 were retreated twice. A range of genotype specific and pangenotypic DAAs were used to retreat virological failure in primary (n=56) and tertiary (n=157) settings. Following sofosbuvir/velpatasvir/voxilaprevir availability in 2019, the proportion retreated in primary care increased from 21% to 40% and median time to retreatment initiation declined from 294 to 152 days. Per-protocol (PP) sustained virological response (SVR12) was similar for people retreated in primary and tertiary settings (80% vs 81%; p=1.000). In regression analysis, sofosbuvir/velpatasvir/voxilaprevir (vs. other regimens) significantly decreased likelihood of second virological failure (PP SVR12 88% vs. 77%; adjusted odds ratio [AOR] 0.29; 95%CI 0.11-0.81); cirrhosis increased likelihood (PP SVR12 69% vs. 91%; AOR 4.26; 95%CI 1.64-11.09). Indigenous Australians had lower likelihood of retreatment initiation (AOR 0.36; 95%CI 0.15-0.81). Treatment setting and prescriber type were not associated with retreatment initiation or outcome. Virological failure can be effectively retreated in primary care. Expanded access to simplified retreatment regimens through decentralised models may increase retreatment uptake and reduce HCV-related mortality.

Abstract
INTRODUCTION Naloxone is a life-saving medication that reverses opioid overdose; naloxone can be provided on a 'take-home' basis so naloxone can be administered outside of the health-care setting. The Overdose Response and Take Home Naloxone (ORTHN) project established a model of care for take-home naloxone (THN) interventions across alcohol and other drug and harm reduction services in NSW, Australia. This paper evaluates the staff training and credentialing program, and examines staff attitudes and perspectives regarding the provision of THN interventions in these settings. METHODS Staff across seven services were trained through a 'train-the-trainer' credentialing model to deliver ORTHN, including naloxone supply. Staff were surveyed regarding their experience, attitudes and knowledge on THN prior to and after training, and after 6 months. At the 6 months follow up, staff were asked about the interventions they provided, barriers and enablers to uptake, and opinions regarding future rollout. RESULTS A total of 204 staff were trained and credentialed to provide the ORTHN intervention. Most (60%) were nurses, followed by needle syringe program workers and allied health/counsellors (32%). Linear and logistic regression analyses indicated that the training program was associated with significant improvements in staff knowledge and attitudes towards overdose and THN; however, only attitudinal improvements were maintained over time. There were high rates of staff satisfaction with the ORTHN intervention and training. DISCUSSION/CONCLUSIONS The ORTHN program is 'fit for purpose' for broad implementation in these settings. A number of potential barriers (e.g. time, medication and staffing costs) and enablers (e.g. peer engagement, regulatory framework for naloxone supply) in implementing THN interventions were identified.

Abstract
BACKGROUND The use of pre-exposure prophylaxis (PrEP) for the prevention of HIV has raised concerns of increased sexual risk behaviours. These behaviours may be associated with increased incidence of sexually acquired hepatitis C (HCV) among gay and bisexual men (GBM). METHODS The Expanded PrEP Implementation in Communities-New South Wales (EPIC-NSW) study was a cohort study of daily co-formulated tenofovir disoproxil fumarate and emtricitabine for HIV prevention. We recruited 9596 people at high risk of HIV acquisition from 31 clinics across New South Wales and the Australia Capital Territory in Australia. We report prior exposure to HCV and incidence in this cohort between 2016 and 2019. RESULTS At least one HCV test result was available for 8658 (90.2%) participants. These individuals had a median age of 34 years (IQR 28-43), most of whom were male (8530, 98.5%), identified as gay (7944, 91.8%), and were born in Australia (51.8%). Prior exposure to HCV was detected among 81 participants at baseline (0.9%, 95% CI 0.7 to 1.2%). Twenty of 8577 participants were diagnosed with incident infection (rate 0.2/100 person years (95%CI 0.1 to 0.3/100py)). They were significantly older (median age 41 years vs 34 years, p=0.044), and more likely to report methamphetamine use at baseline (IRR 2.7 (95%CI 1.00-7.2)) than those without incident infection. CONCLUSIONS In this population of PrEP users, HCV prior exposure and incidence were low. With high levels of HCV and HIV testing and treatment, the dual goals of HIV and HCV elimination could be achieved in this population.

Abstract
Australia was one of the first countries with unrestricted access to government subsidized direct-acting antiviral (DAA) therapy for adults with chronic hepatitis C virus. This study assessed real-world DAA treatment outcomes across a diverse range of Australian clinical services and evaluated factors associated with successful treatment and loss to follow-up. Real-world Effectiveness of Antiviral therapy in Chronic Hepatitis C (REACH-C) consisted a national observational cohort of 96 clinical services including specialist clinics and less traditional settings such as general practice. Data were obtained on consecutive individuals who commenced DAAs from March 2016 to June 2019. Effectiveness was assessed by sustained virological response ≥12 weeks following treatment (SVR) using intention-to-treat (ITT) and per-protocol (PP) analyses. Within REACH-C, 10,843 individuals initiated DAAs (male 69%; ≥50 years 52%; cirrhosis 22%). SVR data were available in 85% (9,174 of 10,843). SVR was 81% (8,750 of 10,843) by ITT and 95% (8,750 of 9,174) by PP. High SVR (≥92%) was observed across all service types and participant characteristics. Male gender (adjusted odds ratio [aOR] 0.56, 95% confidence interval [CI] 0.43-0.72), cirrhosis (aOR 0.52, 95% CI 0.41-0.64), recent injecting drug use (IDU; aOR 0.64, 95% CI 0.46-0.91) and previous DAA treatment (aOR 0.50, 95% CI 0.28-0.90) decreased the likelihood of achieving SVR. Multiple factors modified the likelihood of loss to follow-up including IDU ± opioid agonist therapy (OAT; IDU only: aOR 1.75, 95% CI 1.44-2.11; IDU + OAT: aOR 1.39, 95% CI 1.11-1.74; OAT only, aOR 1.36; 95% CI 1.13-1.68) and age (aOR 0.97, 95% CI 0.97-0.98). Conclusion: Treatment response was high in a diverse population and through a broad range of services following universal access to DAA therapy. Loss to follow-up presents a real-world challenge. Younger people who inject drugs were more likely to disengage from care, requiring innovative strategies to retain them in follow-up.

Abstract
BACKGROUND Understanding factors associated with engagement across the hepatitis C virus (HCV) cascade of care (CoC) among people who inject drugs (PWID) is critical for developing targeted interventions to enhance engagement and further HCV elimination efforts. We describe the CoC among Australian PWID, and identify factors associated with engagement at each stage. METHODS As part of the 2018 and 2019 Illicit Drug Reporting System, Australians who regularly inject drugs reported lifetime HCV antibody and RNA testing, treatment uptake and completion. Multivariable logistic regression identified characteristics associated with outcomes. RESULTS Of 1499 participants, 87% reported antibody testing. Of those, 70% reported RNA testing, of whom 60% reported being RNA positive. Among those, 76% reported initiating treatment, 78% of whom completed. Incarceration history (adjusted odds ratio 1.90; 95% confidence interval 1.28-2.82), current opioid agonist treatment (OAT) (1.99; 1.14-3.47), and recent alcohol and other drug (AOD) counselling (2.22; 1.27-3.88) were associated with antibody testing. Incarceration history (1.42; 1.07-1.87), and current OAT (2.07; 1.51-2.86) were associated with RNA testing. Current OAT (1.92; 1.22-3.03) and recent AOD counselling (1.91; 1.16-3.13) were associated with treatment uptake. Methamphetamine as drug injected most often in the last month was associated with reduced odds of antibody (0.41; 0.25-0.66) and RNA testing (0.54; 0.40-0.74), compared to heroin. CONCLUSION CoC engagement amongst Australian PWID is encouraging, with AOD service engagement associated with testing and treatment. Further efforts to reach those not service engaged, particularly those not receiving OAT or who predominantly inject methamphetamine, are needed to achieve HCV elimination targets.

Abstract
BACKGROUND Overdose is a major cause of morbidity and mortality among people who use opioids. Naloxone can reverse opioid overdoses and can be distributed and administered with minimal training. People with experience of overdose are a key population to target for overdose prevention strategies. This study aims to understand if factors associated with recent non-fatal opioid overdose are the same as factors associated with naloxone access and naloxone training in people who recently used opioids or received opioid agonist treatment (OAT). METHODS ETHOS Engage is an observational study of people who inject drugs in Australia. Logistic regression models were used to estimate odds ratios for non-fatal opioid overdose, naloxone access and naloxone training. RESULTS Between May 2018-September 2019, 1280 participants who recently used opioids or received OAT were enrolled (62% aged >40 years; 35% female, 80% receiving OAT, 62% injected drugs in the preceding month). Recent opioid overdose (preceding 12 months) was reported by 7% of participants, lifetime naloxone access by 17%, and lifetime naloxone training by 14%. Compared to people receiving OAT with no additional opioid use, recent opioid, benzodiazepine (preceding six months), and hazardous alcohol use was associated with recent opioid overdose (aOR 3.91; 95%CI: 1.68-9.10) and lifetime naloxone access (aOR 2.12; 95%CI 1.29-3.48). Among 91 people who reported recent overdose, 65% had never received take-home naloxone or naloxone training. CONCLUSIONS Among people recently using opioids or receiving OAT, benzodiazepine and hazardous alcohol use is associated with non-fatal opioid overdose. Not all factors associated with non-fatal overdose correspond to factors associated with naloxone access. Naloxone access and training is low across all groups. Additional interventions are needed to scale up naloxone provision.

Abstract
BACKGROUND Evaluating progress towards hepatitis C virus (HCV) elimination is critical. This study estimated prevalence of current HCV infection and HCV treatment uptake among people who inject drugs (PWID) in Australia. METHODS The Enhancing Treatment of Hepatitis C in Opioid Substitution Settings Engage is an observational study of PWID attending drug treatment clinics and needle and syringe programs (NSPs). Participants completed a questionnaire including self-reported treatment history and underwent point-of-care HCV RNA testing (Xpert HCV Viral Load Fingerstick; Cepheid). RESULTS Between May 2018 and September 2019, 1443 participants were enrolled (64% injected drugs in the last month, 74% receiving opioid agonist therapy [OAT]). HCV infection status was uninfected (28%), spontaneous clearance (16%), treatment-induced clearance (32%), and current infection (24%). Current HCV was more likely among people who were homeless (adjusted odds ratio, 1.47; 95% confidence interval, 1.00-2.16), incarcerated in the previous year (2.04; 1.38-3.02), and those injecting drugs daily or more (2.26; 1.43-2.42). Among those with previous chronic or current HCV, 66% (n = 520/788) reported HCV treatment. In adjusted analysis, HCV treatment was lower among females (.68; .48-.95), participants who were homeless (.59; .38-.96), and those injecting daily or more (.51; .31-.89). People aged ≥45 years (1.46; 1.06-2.01) and people receiving OAT (2.62; 1.52-4.51) were more likely to report HCV treatment. CONCLUSIONS Unrestricted direct-acting antiviral therapy access in Australia has yielded high treatment uptake among PWID attending drug treatment and NSPs, with a marked decline in HCV prevalence. To achieve elimination, PWID with greater marginalization may require additional support and tailored strategies to enhance treatment.

Abstract
BACKGROUND People who inject drugs (PWID) experience barriers to accessing testing and treatment for hepatitis C virus (HCV) infection. Opioid agonist therapy (OAT) may provide an opportunity to improve access to HCV care. This systematic review assessed the association of OAT and HCV testing, treatment, and treatment outcomes among PWID. METHODS Bibliographic databases and conference presentations were searched for studies that assessed the association between OAT and HCV testing, treatment, and treatment outcomes (direct-acting antiviral [DAA] therapy only) among PWID (in the past year). Meta-analysis was used to pool estimates. RESULTS Of 9877 articles identified, 22 studies conducted in Australia, Europe, North America, and Thailand were eligible and included. Risk of bias was serious in 21 studies and moderate in 1 study. Current/recent OAT was associated with an increased odds of recent HCV antibody testing (4 studies; odds ratio (OR), 1.80; 95% confidence interval [CI], 1.36-2.39), HCV RNA testing among those who were HCV antibody-positive (2 studies; OR, 1.83; 95% CI, 1.27-2.62), and DAA treatment uptake among those who were HCV RNA-positive (7 studies; OR, 1.53; 95% CI, 1.07-2.20). There was insufficient evidence of an association between OAT and treatment completion (9 studies) or sustained virologic response following DAA therapy (9 studies). CONCLUSIONS OAT can increase linkage to HCV care, including uptake of HCV testing and treatment among PWID. This supports the scale-up of OAT as part of strategies to enhance HCV treatment to further HCV elimination efforts.

Abstract
BACKGROUND Daily pre-exposure prophylaxis (PrEP) is effective in preventing HIV, but few long-term data are available on effectiveness and adherence in real-world settings. Here, we report trends in HIV incidence over 3 years in individuals at high risk who were prescribed PrEP in New South Wales (NSW), as well as adherence before the transition to subsidised PrEP. METHODS Expanded PrEP Implementation in Communities-New South Wales (EPIC-NSW) was a pragmatic, prospective, single-arm, implementation study of daily, oral PrEP in 31 sites (sexual health clinics, general practices, and a hospital) in NSW, Australia. Eligible participants were HIV-negative adults (aged ≥18 years) who were at high risk of HIV infection as defined in local PrEP guidelines. Participants were prescribed coformulated (once-daily, oral tablet) tenofovir disoproxil fumarate (300 mg) and emtricitabine (200 mg) as HIV PrEP and were followed up with HIV testing, sexually transmitted infection testing, and PrEP dispensing. Originally planned for 3700 participants followed for 1 year, the study was expanded so that all eligible participants in the state could obtain PrEP and extended until publicly subsidised PrEP became available in Australia. The primary outcome was new HIV infection among all participants who were dispensed PrEP at least once and had at least one follow-up HIV test result. Adherence was estimated by medication possession ratio (MPR), defined as the proportion of PrEP pills dispensed in 90 days, assuming daily dosing. This study is registered with ClinicalTrials.gov, NCT02870790. FINDINGS Between March 1, 2016, and April 30, 2018, we enrolled 9709 participants. 9596 participants were dispensed PrEP, of whom 9448 (98·3%) were gay or bisexual men. Participants were followed up until March 31, 2019, with at least one follow-up HIV test available in 9520 (99·2%) participants. Mean MPR declined from 0·93 to 0·64 from the first to the ninth quarter. There were 30 HIV seroconversions over 18 628 person-years, an incidence of 1·61 per 1000 person-years (95% CI 1·13-2·30). Being younger, living in a postcode with fewer gay men, reporting more risk behaviours at baseline, and having an MPR of less than 0·6 were each univariately associated with increased HIV incidence. In the final year of follow-up, when PrEP was mostly purchased rather than provided free by the study, HIV incidence remained low at 2·24 per 1000 person-years (1·46-3·44). INTERPRETATION HIV incidence remained low over up to 3 years of follow-up, including during a transition from study-provided to publicly subsidised PrEP. In a setting of affordable PrEP and associated health-care services, very low HIV incidence of 1 to 2 per 1000 person-years can be maintained in gay and bisexual men who were previously at high risk.

Abstract
BACKGROUND The aim of this analysis was to calculate the incidence of hepatitis C virus (HCV) reinfection and associated factors among 2 clinical trials of HCV direct-acting antiviral treatment in people with recent injecting drug use or currently receiving opioid agonist therapy (OAT). METHODS Participants who achieved an end-of-treatment response in 2 clinical trials of people with recent injecting drug use or currently receiving OAT (SIMPLIFY and D3FEAT) enrolled between March 2016 and February 2017 in 8 countries were assessed for HCV reinfection, confirmed by viral sequencing. Incidence was calculated using person-time of observation and associated factors were assessed using Cox proportional hazard models. RESULTS Seventy-three percent of the population at risk of reinfection (n = 177; median age, 48 years; 73% male) reported ongoing injecting drug use. Total follow-up time at risk was 254 person-years (median, 1.8 years; range, 0.2-2.8 years). Eight cases of reinfection were confirmed for an incidence of 3.1/100 person-years (95% confidence interval [CI], 1.6-6.3) overall and 17.9/100 person-years (95% CI, 5.8-55.6) among those who reported sharing needles/syringes. Younger age and needle/syringe sharing were associated with HCV reinfection. CONCLUSIONS These data demonstrate the need for ongoing monitoring and improved strategies to prevent HCV reinfection following successful treatment among people with ongoing injecting drug use to achieve HCV elimination.

Abstract
OBJECTIVES To evaluate the impact of government HIV strategies that aimed to increase HIV testing uptake and frequency among gay and bisexual men (GBM) in New South Wales (NSW), Australia. DESIGN We analysed HIV testing data from existing passive and sentinel surveillance systems between 2010 and 2018. METHODS Six indicators were measured: (1) state-wide total HIV laboratory tests; (2) number of GBM attending publicly-funded clinics; (3) 12-monthly testing uptake; (4) annual testing frequency; (5) HIV testing with a STI diagnosis; and (6) HIV positivity. Mathematical modelling was used to estimate (7) the proportion of men with undiagnosed HIV. Indicators were stratified by Australian vs. overseas-born. RESULTS Overall, 43,560 GBM attended participating clinics (22,662 Australian-born, 20,834 overseas-born) from 2010-2018. Attendees increased from 5,186 in 2010 to 16,507 in 2018. There were increasing trends (p<0.001 for all) in testing uptake (83.9% to 95.1%); testing with a STI diagnosis (68.7% to 94.0%); annual HIV testing frequency (1.4 to 2.7); and a decreasing trend (p<0.01) in HIV positivity (1.7% to 0.9%).Increases in testing were similar in Australian-born and overseas-born GBM. However, there were decreasing trends in the estimated undiagnosed HIV proportion overall (9.5% to 7.7%) and in Australian-born GBM (7.1% to 2.8%), but an increasing trend in overseas-born GBM (15.3% to 16.9%) (p<0.001 for all).

Abstract
Background People who inject drugs (PWID) are a priority for HIV prevention. This study aimed to determine perceptions, potential eligibility and willingness to use PrEP among PWID in Sydney. METHODS Clients completed a cross-sectional survey to collect data on demographics, perceived risk of HIV and willingness to use PrEP, which were then analysed. RESULTS Twelve (7%) of 172 HIV-negative participants were eligible for PrEP under current guidelines for injecting reasons, of whom three would also be eligible for sexual risk, leaving nine (5%) eligible for injecting reasons alone. Half had heard of PrEP and, of these, 65% would consider taking it. Most (88%) thought they would continue using needle syringe program services. A minority (8%) indicated they may be likely to share needles and syringes or be less concerned about injecting partners' HIV status (26%). CONCLUSIONS Although PrEP will benefit a small proportion of PWID, this may equate to a significant number nationally. Policy development around PrEP incorporating affected populations will best support the community of people currently injecting to keep rates of HIV low.

Abstract
BACKGROUND AND AIMS Direct-acting antiviral therapy for hepatitis C virus (HCV) is effective, but few prospective studies among people with ongoing injecting drug use exist. This study evaluated the efficacy of elbasvir/grazoprevir in people with HCV genotype 1/4 (G1/4) infection and recent injecting drug use. An exploratory aim evaluated the feasibility of fingerstick point-of-care HCV RNA testing prior to and following treatment. METHODS DARLO-C (http://clinicaltrials.gov: NCT02940691) is an open-label phase 4 trial. Participants were recruited between May 2017 and March 2018 from two drug treatment clinics, two hospital clinics, and one community clinic in Australia. Inclusion criteria included recent injection drug use (previous 6 months) and HCV G1/4 infection. Exclusion criteria included prior HCV treatment and decompensated liver disease. Participants received elbasvir/grazoprevir once-daily for 12 weeks. The primary endpoint was undetectable HCV RNA 12 weeks post-treatment (SVR). Fingerstick whole-blood samples were tested using the Xpert HCV Viral Load Fingerstick (Xpert HCV VL Fingerstick) assay and compared to the Aptima HCV Quant Dx Assay on plasma samples. RESULTS Of a planned 150 participants, 32 were enrolled due to slower than anticipated recruitment [median age 46 years, 10 (31%) female, 29 (91%) G1a]. Eighteen (56%) were receiving opioid agonist therapy and 29 (91%) injected in the previous month. Twenty-six (81%) of 32 completed treatment (lost to follow-up, n = 5; incarceration, n = 1). There were no virological failures. Twenty-four (75%, 95% CI 59%-91%) of 32 achieved SVR. Two participants who completed treatment did not have SVR (loss to follow-up, n = 1; refused test, n = 1). Among paired samples (n = 36), sensitivity of the Xpert HCV VL Fingerstick assay for HCV RNA detection was 100.0% (95% CI 75.3%-100.0%) and specificity was 95.7% (95% CI 78.1%-99.9%). CONCLUSION Elbasvir/grazoprevir is effective among people with HCV G1 with recent injecting drug use. Implementation of point-of-care HCV RNA testing was feasible, but the high error rate requires investigation.

Abstract
Gaps in hepatitis C virus (HCV) testing, diagnosis, liver disease assessment and treatment uptake among people who inject drugs (PWID) persist. We aimed to describe the cascade of HCV care among PWID in Australia, prior to and following unrestricted access to direct-acting antiviral (DAA) treatment. Participants enrolled in an observational cohort study between 2014 and 2018 provided fingerstick whole-blood samples for dried blood spot, Xpert HCV Viral Load and venepuncture samples. Participants underwent transient elastography and clinical assessment by a nurse or general practitioner. Among 839 participants (mean age 43 years), 66% were male (n = 550), 64% (n = 537) injected drugs in the previous month, and 67% (n = 560) reported currently receiving opioid substitution therapy. Overall, 45% (n = 380) had detectable HCV RNA, of whom 23% (n = 86) received HCV treatment within 12 months of enrolment. HCV treatment uptake increased from 2% in the pre-DAA era to 38% in the DAA era. Significant liver fibrosis (F2-F4) was more common in participants with HCV infection (38%) than those without (19%). Age 50 years or older (aOR, 2.88; 95% CI, 1.18-7.04) and attending a clinical follow-up with nurse (aOR, 3.19; 95% CI, 1.61-6.32) or physician (aOR, 11.83; 95% CI, 4.89-28.59) were associated with HCV treatment uptake. Recent injection drug use and unstable housing were not associated with HCV treatment uptake. HCV treatment uptake among PWID has increased markedly in the DAA era. Evaluation of innovative and simplified models of care is required to further enhance treatment uptake.

Abstract
INTRODUCTION AND DESIGNS Take-home naloxone (THN) interventions are an effective response to preventing overdose deaths, however uptake across Australia remains limited. This project designed, implemented and evaluated a model of care targeting opioid users attending alcohol and other drug (AOD) treatment, needle and syringe programs (NSP) and related health services targeting people who inject drugs. DESIGN AND METHODS Service providers, consumers and regulators collaboratively designed a THN brief intervention (ORTHN, Overdose Response with Take-Home Naloxone) involving client education and supply of naloxone in pre-filled syringes, delivered by nursing, allied health and NSP workers. ORTHN interventions were implemented in over 15 services across New South Wales, Australia. The evaluation included client knowledge, attitudes, substance use and overdose experiences immediately before and 3 months after ORTHN intervention in a subsample of participants. RESULTS Six hundred and sixteen interventions were delivered, with 145 participants recruited to the research subsample, of whom 95 completed the three-month follow up. Overdose-related attitudes amongst participants improved following ORTHN, with no evidence of increased substance use or failure to implement other 'first responses' (e.g. calling an ambulance). Nine participants (10%) reversed an overdose using THN in the follow-up period. Participants identified a willingness to access THN from a range of services. While a minority (16%) indicated they were unwilling to pay for THN, the median price that participants were willing to pay was $AUD20 (IQR $10.40). DISCUSSION AND CONCLUSIONS The ORTHN model of care for THN appears an effective way to disseminate THN to people who use opioids attending AOD, NSP and related health-care settings.

Abstract
The Australian sexually transmissible infection and HIV testing guidelines for asymptomatic men who have sex with men were updated in 2014. An evaluation study targeting Sydney-based general practitioners was conducted among 85 clinicians. Respondents with knowledge of guideline recommendations were significantly more likely to feel comfortable asking men who have sex with men about their sexual history (98.1% vs 81.3%, P=0.039), and to recommend at least annual testing (94.0% vs 68.8%, P=0.015), 3-month retesting after chlamydia or gonorrhoea treatment (96.2% vs 73.3%, P=0.017) and syphilis testing with routine HIV monitoring bloods (90.2% vs 57.1%, P=0.037). Familiarity with the guidelines was associated with a range of positive outcomes on general practitioners' clinical practice. Novel approaches are required to ensure more widespread distribution of future guidelines.

Abstract
Abstract
Background
This study investigated adherence and associated factors among people with recent injection drug use (IDU) or current opioid agonist therapy (OAT) and compared once-daily to twice-daily hepatitis C virus (HCV) direct-acting antiviral (DAA) therapy.
Methods
SIMPLIFY and D3FEAT are international, multicenter studies that recruited participants with recent IDU (previous 6 months; SIMPLIFY, D3FEAT) or current OAT (D3FEAT) between March 2016 and February 2017 in 8 countries. Participants received sofosbuvir/velpatasvir (once daily; SIMPLIFY) or paritaprevir/ritonavir/ombitasvir, dasabuvir (twice daily) ± ribavirin (D3FEAT) for 12 weeks administered in electronic blister packs. We evaluated overall adherence (proportion of prescribed doses taken) and nonadherence (<90% adherent) between dosing patterns.
Results
Of 190 participants, 184 (97%) completed treatment. Median adherence was 92%, with higher adherence among those receiving once-daily vs twice-daily therapy (94% vs 87%, P = .005). Overall, 40% of participants (n = 76) were nonadherent (<90% adherent). Recent stimulant injecting (odds ratio [OR], 2.48 [95% confidence interval {CI}, 1.28–4.82]), unstable housing (OR, 2.18 [95% CI, 1.01–4.70]), and twice-daily dosing (OR, 2.81 [95% CI, 1.47–5.36]) were associated with nonadherence. Adherence decreased during therapy. Sustained virologic response was high in nonadherent (89%) and adherent populations (95%, P = .174), with no difference in SVR between those who did and did not miss 7 consecutive doses (92% vs 93%, P = .897).
Conclusions
This study demonstrated high adherence to once- and twice-daily DAA therapy among people with recent IDU or currently receiving OAT. Nonadherence described did not impact treatment outcomes, suggesting forgiveness to nonadherence.

Abstract
Globally, some 71 million people are chronically infected with hepatitis C virus (HCV). Marginalized populations, particularly people who inject drugs (PWID), have low testing, linkage to care and treatment rates for HCV. Several models of care (MoCs) and service delivery interventions have the potential to improve outcomes across the HCV cascade of care, but much of the relevant research was carried out when interferon-based treatment was the standard of care. Often it was not practical to scale-up these earlier models and interventions because the clinical care needs of patients taking interferon-based regimens imposed too much of a financial and human resource burden on health systems. Despite the adoption of highly effective, all-oral direct-acting antiviral (DAA) therapies in recent years, approaches to HCV testing and treatment have evolved slowly and often remain rooted in earlier paradigms. The effectiveness of DAAs allows for simpler approaches and has encouraged countries where the drugs are widely available to set their sights on the ambitious World Health Organization (WHO) HCV elimination targets. Since a large proportion of chronically HCV-infected people are not currently accessing treatment, there is an urgent need to identify and implement existing simplified MoCs that speak to specific populations' needs. This article aims to: (i) review the evidence on MoCs for HCV; and (ii) distil the findings into recommendations for how stakeholders can simplify the path taken by chronically HCV-infected individuals from testing to cure and subsequent care and monitoring.

Abstract
A community-based public health facility in Sydney, Australia, the Kirketon Road Centre (KRC), provides health care to people who inject drugs (PWID), homeless and other marginalized people. Since March 2016, KRC has provided treatment for chronic hepatitis C virus (HCV) with direct-acting antivirals (DAAs). We aimed to evaluate treatment adherence amongst clients taking DAAs in a highly marginalized population. All clients who commenced DAA therapy prior to March 2018 at KRC were included in this observational cohort with a subset of clients attending daily or weekly for enhanced adherence support and dosing. Demographic, behavioural, clinical measures and medication dosing were recorded, and adherence was calculated as the proportion of doses taken during the expected treatment duration. Factors associated with adherence were examined using logistic regression. A total of 242 individuals commenced DAA therapy, of whom 79 (32%) received enhanced adherence support. Enhanced support was associated with homelessness, daily injecting, Aboriginality, mental health co-morbidity and poly-drug use (all P < .001). Overall adherence was 86%, and 92% of patients missed one or more doses (median 10, IQR 4-24). At least 90% adherence during planned duration was seen in 38%, but increased to 66% by continuing therapy beyond planned duration. Intention-to-treat SVR12 was 68% and 66% in the enhanced adherence support sub-population, with 29% lost to follow-up by SVR12 testing. There were only 2 (0.8%) documented virological failures. Per-protocol SVR12 was 99% and 96% in the enhanced adherence support sub-population. In conclusion, adherence support may benefit those with multiple markers of marginalization. Extension of therapy beyond planned duration is a pragmatic strategy to enhance completion. Strategies to improve follow-up, particularly post-treatment are required.

Abstract
UNLABELLED Background In HIV-positive people, sexually transmissible infections (STIs) probably increase the infectiousness of HIV. METHODS In 2010, we established a cohort of individuals (n=554) from clinics in the Australian HIV Observational Database (AHOD). We calculated retrospective rates for four STIs for 2005-10 and prospective incidence rates for 2010-11. RESULTS At baseline (2010), patient characteristics were similar to the rest of AHOD. Overall incidence was 12.5 per 100 person-years. Chlamydial infections increased from 3.4 per 100 person-years (95% confidence interval (CI): 1.9-5.7) in 2005 to 6.7 per 100 person-years (95% CI: 4.5-9.5) in 2011, peaking in 2010 (8.1 per 100 person-years; 95% CI: 5.6-11.2). Cases were distributed among rectal (61.9%), urethral (34%) and pharyngeal (6.3%) sites. Gonococcal infections increased, peaking in 2010 (4.7 per 100 person-years; 95% CI: 5.6-11.2; Ptrend=0.0099), distributed among rectal (63.9%), urethral (27.9%) and pharyngeal (14.8%) sites. Syphilis showed several peaks, the largest in 2008 (5.3 per 100 person-years; 95% CI: 3.3-8.0); the overall trend was not significant (P=0.113). Genital warts declined from 7.5 per 100 person-years (95% CI: 4.8-11.3) in 2005 to 2.4 per 100 person-years (95% CI: 1.1-4.5) in 2011 (Ptrend=0.0016). CONCLUSIONS For chlamydial and gonococcal infections, incidence was higher than previous Australian estimates among HIV-infected men who have sex with men, increasing during 2005-2011. Rectal infections outnumbered infections at other sites. Syphilis incidence remained high but did not increase; that of genital warts was lower and decreased.

Abstract
Abstract
Background
Microelimination of hepatitis C virus (HCV) among people living with human immunodeficiency virus (HIV) may be feasible in Australia, given unrestricted access to direct-acting antiviral (DAA) therapy from 2016. Our aim was to evaluate progress towards elimination goals within HIV/HCV-coinfected adults in Australia following universal DAA access.
Methods
The CEASE prospective cohort study enrolled adults with HIV/HCV, irrespective of viremic status, from 14 primary and tertiary clinics in Australia. Annual and cumulative HCV treatment uptake, outcome, and HCV RNA prevalence were evaluated, with follow-up through May 2018 (median follow-up, 2.63 years). Factors associated with DAA uptake were analyzed.
Results
Between July 2014 and March 2017, 402 participants who were HIV/HCV antibody positive were enrolled (95% male [80% gay and bisexual men,], 13% cirrhosis, 80% history of injecting drug use [39% currently injecting]). Following universal DAA access, annual HCV treatment uptake in those eligible increased from 7% and 11% per year in 2014 and 2015, respectively, to 80% in 2016. By 2018, cumulative HCV treatment uptake in those ever eligible for treatment was 91% (336/371). HCV viremic prevalence declined from 82% (95% CI, 78–86%) in 2014 to 8% (95% CI, 6–12%) in 2018. Reinfection was reported in only 5 participants for a reinfection incidence of 0.81 per 100 person-years (95% CI, 0.34–1.94).
Conclusions
High uptake and effectiveness of unrestricted DAA therapy in Australia have permitted rapid treatment scale-up, with a dramatic reduction in HCV infection burden and low reinfection rate among people living with HIV, suggesting that microelimination is feasible.

Abstract
OBJECTIVES To estimate rates of HIV infection, chlamydia, gonorrhoea, and infectious syphilis in transgender men and women in Australia; to compare these rates with those for cisgender people. DESIGN Cross-sectional, comparative analysis of de-identified health data. SETTING, PARTICIPANTS We analysed data for 1260 transgender people (404 men, 492 women, 364 unrecorded gender), 78 108 cisgender gay and bisexual men, and 309 740 cisgender heterosexual people who attended 46 sexual health clinics across Australia during 2010-2017. MAIN OUTCOME MEASURES First-visit test positivity for sexually transmitted infections (STIs), stratified by patient group and year; demographic and behavioural factors associated with having STIs. RESULTS 14 of 233 transgender men (6.0%) and 34 of 326 transgender women (10%) tested during first clinic visits were chlamydia-positive; nine transgender men (4%) and 28 transgender women (8.6%) were gonorrhoea-positive. One of 210 tested transgender men (0.5%) and ten of 324 tested transgender women (3.1%) were diagnosed with infectious syphilis; 14 transgender men (3.5%) and 28 transgender women (5.7%) were HIV-positive at their first visit. The only significant change in prevalence of an STI among transgender patients during the study period was the increased rate of gonorrhoea among transgender women (from 3.1% to 9.8%). Compared with cisgender gay and bisexual men, transgender men were less likely (adjusted odds ratio [aOR], 0.46; 95% CI, 0.29-0.71; P = 0.001) and transgender women as likely (aOR, 0.98; 95% CI, 0.73-1.32; P = 0.92) to be diagnosed with a bacterial STI; compared with heterosexual patients, transgender men were as likely (aOR, 0.72; 95% CI, 0.46-1.13; P = 0.16) and transgender women more likely (aOR, 1.56; 95% CI, 1.16-2.10; P = 0.003) to receive a first-visit bacterial STI diagnosis. CONCLUSIONS The epidemiology of STIs in transgender people attending Australian sexual health clinics differs from that of cisgender patients. Gender details must be captured by health data systems to facilitate appropriate delivery of sexual health care.

Abstract
People who are homeless have increased hepatitis C virus (HCV) infection risk, and are less likely to access primary healthcare. We aimed to evaluate HCV RNA prevalence, liver disease burden, linkage to care and treatment uptake and outcomes among people attending a homelessness service in Sydney. Participants were enrolled in an observational cohort study with recruitment at a homelessness service over eight liver health campaign days. Finger-stick whole-blood samples for Xpert® HCV Viral Load and venepuncture blood samples were collected. Participants completed a self-administered survey and received transient elastography and clinical assessment by a general practitioner or nurse. Clinical follow-up was recommended 2-12 weeks after enrolment. For participants initiating direct-acting antiviral (DAA) therapy, medical records were audited retrospectively and treatment outcome data were collected. Among 202 participants (mean age, 48 years), 82% were male (n = 165), 39% (n = 78) reported ever injecting drugs, of whom 63% (n = 49) injected in the previous month. Overall, 23% (n = 47) had detectable HCV RNA and 6% (n=12) had cirrhosis. HCV RNA prevalence among participants with either injecting or incarceration history was 35% (37/105), compared to 4% (3/73) among participants without these risk factors. Among those with detectable HCV RNA, 23 (49%) commenced therapy, of whom 65% (n = 15) achieved sustained virological response, while the remainder had no available treatment outcome. No participant had documented virological failure. HCV DAA treatment uptake among people attending a homelessness service was encouraging, but innovative models of HCV care are required to improve linkage to care and treatment uptake among this highly marginalized population.

Abstract
BACKGROUND This study investigated treatment adherence among people with recent injecting drug use in a study of sofosbuvir/velpatasvir therapy for HCV infection. METHODS SIMPLIFY is an international open-label, single-arm multicentre study that recruited participants with recent injecting drug use (previous six months) and chronic HCV genotype (G) 1-6 infection between March and October 2016 in seven countries (19 sites). Participants received sofosbuvir/velpatasvir once-daily for 12 weeks administered in a one-week electronic blister pack (records the time and date of each dose) for 12 weeks. We evaluated non-adherence (<90% adherent) as measured by electronic blister-pack assessed using logistic regression and generalised estimating equations (continuous) with detailed analyses of dosing dynamics. RESULTS Among 103 participants, 97% (n = 100) completed treatment. Median adherence to therapy was 94%. Overall, 32% (n = 33) were considered non-adherent (<90% adherence). Adherence significantly decreased over the course of therapy. Recent stimulant injecting (cocaine and/or amphetamines) at treatment initiation and during treatment was independently associated with non-adherence. Inconsistent dose timing (standard deviation of daily dose timing of ≥240 min) was also independently associated with non-adherence to therapy. Factors associated with inconsistent dose timing included lower levels of education and recent stimulant injecting. SVR was similar among adherent and non-adherent populations (94% vs. 94%, P = 0.944). CONCLUSION This study demonstrated high adherence to once-daily sofosbuvir/velpatasvir therapy among a population of people with recent injecting drug use. Recent stimulant injecting prior to and during DAA therapy and inconsistent dose-timing during treatment was associated with non-adherence. However, there was no impact of non-adherence on response to therapy, suggesting that adherence is not a significant barrier to successful DAA therapy in people with recent injecting drug use.

Abstract
Background Syphilis rates have increased markedly among men who have sex with men (MSM) internationally. We examined trends in syphilis testing and detection of early syphilis among MSM in Australia. Methods Serial cross-sectional analyses on syphilis testing and diagnoses among MSM attending a national sentinel network of 46 clinics in Australia between 2007 and 2014. Results 359313 clinic visits were included. The proportion of MSM serologically tested for syphilis annually increased in HIV-negative (48% to 91%; Ptrend < .0001) and HIV-positive MSM (42% to 77%; Ptrend < .0001). The mean number of tests per man per year increased from 1.3 to 1.6 in HIV-negative MSM (Ptrend < .0001) and from 1.6 to 2.3 in HIV-positive MSM (Ptrend < .0001). 2799 and 1032 syphilis cases were detected in HIV-negative and HIV-positive MSM, respectively. Among HIV-negative MSM, the proportion of infections that were early latent increased from 27% to 44% (Ptrend < .0001), while the proportion that were secondary decreased from 24% to 19% (Ptrend = .030). Among HIV-positive MSM, early latent infections increased from 23% to 45% (Ptrend < .0001), while secondary infections decreased from 45% to 26% (Ptrend = .0003). Among HIV-positive MSM, decreasing secondary syphilis correlated with increasing testing coverage (r = -0.87; P = .005) or frequency (r = -0.93; P = .001). Conclusions Increases in syphilis screening were associated with increased detection of asymptomatic infectious syphilis and relative falls in secondary syphilis for both HIV-positive and HIV-negative MSM nationally, suggesting interruption of syphilis progression.

Abstract
BACKGROUND Despite revised guidelines that no longer exclude people who inject drugs (PWID) from treatment for hepatitis C virus (HCV) infection, many clinicians are reluctant to treat recent PWID. This study aimed to evaluate the efficacy of sofosbuvir and velpatasvir therapy in people with chronic HCV infection and recent injection drug use. METHODS In this open-label, single-arm phase 4 trial (SIMPLIFY), we recruited participants with recent injection drug use (past 6 months) and chronic HCV genotype 1-6 infection from seven countries (19 sites). Participants received oral sofosbuvir (400 mg) and velpatasvir (100 mg) once daily for 12 weeks. Therapy was given in 1-week electronic blister packs to record the time and date of each dose. The primary endpoint was the proportion of patients with sustained virological response 12 weeks after completion of treatment (SVR12; defined as HCV RNA <12 IU/mL), analysed in all patients who received at least one dose. This study is registered with ClinicalTrials.gov, number NCT02336139, and follow-up is ongoing to evaluate the secondary endpoint of HCV reinfection. FINDINGS Between March 29, and Oct 31, 2016, we enrolled 103 participants; 29 (28%) of whom were female, nine (9%) had cirrhosis, 36 (35%) had HCV genotype 1, five (5%) had genotype 2, 60 (58%) had genotype 3, and two (2%) had genotype 4. 61 (59%) participants were receiving opioid substitution therapy during the study, 76 (74%) injected in the past month, and 27 (26%) injected at least daily in the past month. 100 (97%) of 103 participants completed treatment; two people were lost to follow-up and one person died from an overdose. There were no virological failures. 97 (94%, 95% CI 88-98) of 103 people achieved SVR12. Three participants with an end-of-treatment response did not have a SVR; two were lost to follow-up and one had reinfection. Drug use before and during treatment did not affect SVR12. Treatment-related adverse events were seen in 48 (47%) patients (one grade 3, no grade 4). Seven (7%) patients had at least one serious adverse event; only one such event (rhabdomyolysis, resolved) was possibly related to the therapy. One case of HCV reinfection was observed. INTERPRETATION HCV treatment should be offered to PWID, irrespective of ongoing drug use. Recent injection drug use should not be used as a reason to withhold reimbursement of HCV therapy.
