This Note discusses efforts to defeat government censorship of the Internet. In the narrow meaning of that idea, this Note initially discusses technological efforts to circumvent government-imposed Internet firewalls; in the broader sense, it addresses the larger goal of inducing censoring governments to bring their firewalls down. Proposed U.S. legislation would provide U.S. government funding of censorship circumvention technology. This Note discusses why such funding is not a good approach. Absent larger international efforts, private action--within both the U.S. and censoring countries--has the best chance of bringing down government-run firewalls. This Note discusses how the U.S. government can best facilitate such private action through a two-pronged approach. The approach attempts to increase private circumvention efforts while decreasing U.S. corporate assistance in foreign governments' censoring. This Note argues that such an approach would result in the possibility of censoring governments bringing down their firewalls because of an increased demand for an uncensored Internet and sufficient government frustration in maintaining such censorship.

Hepatitis C virus (HCV) is a global public health problem in correctional settings. The International Network on Health and Hepatitis in Substance Users–Prisons Network is a special interest group committed to advancing scientific knowledge exchange and advocacy for HCV prevention and care in correctional settings. In this Review, we highlight seven priority areas and best practices for improving HCV care in correctional settings: changing political will, ensuring access to HCV diagnosis and testing, promoting optimal models of HCV care and treatment, improving surveillance and monitoring of the HCV care cascade, reducing stigma and tackling the social determinants of health inequalities, implementing HCV prevention and harm reduction programmes, and advancing prison-based research.

Research on quality adjusted life year (QALY) has been underway for just over 50 years, which seems like a suitable milestone to review its history. The purpose of this study is to provide a historical overview of why the QALY was developed, the key theoretical work undertaken by Torrance, Bush and Fanshel and how two seminal papers shaped its subsequent development. Moving the QALY forward – there are several historical and reflective exercises. The historical interplay between politics, policy and the challenges facing the National Health Service (NHS) in formulating the QALY concept in the UK has been explored in some depth already, whilst the conceptualization and development of the methodological framework is relatively underexplored. We address this gap by viewing the QALY through the lens of the methodological debates, reflecting upon two key papers underpinning the QALY methodology and how these methods have been developed over time. In part the changes in technology e.g. Google Scholar, and the availability of tools to search for early uses of the QALY allow us to better understand the historical context in which the theoretical development of the QALY has taken place. Here we celebrate two seminal papers that shaped early QALY development. The first section provides a history of these papers, summaries their contributions and explores the uptake of these papers over time. The second section reviews the methodological debates that have surrounded the QALY over the last 50 years and looks at how the QALY has moved to address these challenges. The third section presents the voices of diverse commentators representing the field of health economics who have contributed to the subsequent development of the QALY in both theoretical and empirical capacities and captures their thoughts about future research and policy use of QALYS.

AbstractIntroductionOver the last two decades, the incidence of hepatitis C virus (HCV) co‐infection among men who have sex with men (MSM) living with HIV began increasing in post‐industrialized countries. Little is known about transmission of acute or recent HCV, in particular among MSM living with HIV co‐infection, which creates uncertainty about potential for reinfection after HCV treatment. Using phylogenetic methods, clinical, epidemiological and molecular data can be combined to better understand transmission patterns. These insights may help identify strategies to reduce reinfection risk, enhancing effectiveness of HCV treatment as prevention strategies. The aim of this study was to identify multi‐risk profiles and factors associated with phylogenetic pairs and clusters among people with recent HCV infection.MethodsData and specimens from five studies of recent HCV in Australia and New Zealand (2004 to 2015) were used. HCV Core‐E2 sequences were used to infer maximum likelihood trees. Clusters were identified using 90% bootstrap and 5% genetic distance threshold. Multivariate logistic regression and latent class analyses were performed.ResultsAmong 237 participants with Core‐E2 sequences, 47% were in a pair/cluster. Among HIV/HCV co‐infected participants, 60% (74/123) were in a pair/cluster, compared to 30% (34/114) with HCV mono‐infection (p < 0.001). HIV/HCV co‐infection (vs. HCV mono‐infection; adjusted odds ratio (AOR), 2.37, 95% confidence interval (CI), 1.45, 5.15) was independently associated with phylogenetic clustering. Latent class analysis identified three distinct risk profiles: (1) people who inject drugs, (2) HIV‐positive gay and bisexual men (GBM) with low probability of injecting drug use (IDU) and (3) GBM with IDU & sexual risk behaviour. Class 2 (vs. Class 1, AOR 3.40; 95% CI, 1.52, 7.60), was independently associated with phylogenetic clustering. Many clusters displayed homogeneous characteristics, such as containing individuals exclusively from one city, individuals all with HIV/HCV co‐infection or individuals sharing the same route of acquisition of HCV.ConclusionsClusters containing individuals with specific characteristics suggest that HCV transmission occurs through discrete networks, particularly among HIV/HCV co‐infected individuals. The greater proportion of clustering found among HIV/HCV co‐infected participants highlights the need to provide broad direct‐acting antiviral access encouraging rapid uptake in this population and ongoing monitoring of the phylogeny.

The burden of hepatitis C infection is considerable among people who inject drugs (PWID), with an estimated prevalence of 39%, representing an estimated 6.1 million people who have recently injected drugs living with hepatitis C infection. As such, PWID are a priority population for enhancing prevention, testing, linkage to care, treatment and follow-up care in order to meet World Health Organization (WHO) hepatitis C elimination goals by 2030. There are many barriers to enhancing hepatitis C prevention and care among PWID including poor global coverage of harm reduction services, restrictive drug policies and criminalization of drug use, poor access to health services, low hepatitis C testing, linkage to care and treatment, restrictions for accessing DAA therapy, and the lack of national strategies and government investment to support WHO elimination goals. On 5 September 2017, the International Network of Hepatitis in Substance Users (INHSU) held a roundtable panel of international experts to discuss remaining challenges and future priorities for action from a health systems perspective. The WHO health systems framework comprises six core components: service delivery, health workforce, health information systems, medical procurement, health systems financing, and leadership and governance. Communication has been proposed as a seventh key element which promotes the central role of affected community engagement. This review paper presents recommended strategies for eliminating hepatitis C as a major public health threat among PWID and outlines future priorities for action within a health systems framework.
