Cost and cost-effectiveness of a real-world HCV treatment program among HIV-infected individuals in Myanmar
Introduction Over half of those hepatitis C virus (HCV)/HIV coinfected live in low-income and middle-income countries, and many remain undiagnosed or untreated. In 2016, Médecins Sans Frontières (MSF) established a direct-acting antiviral (DAA) treatment programme for people HCV/HIV coinfected in Myanmar. The purpose of our study was to evaluate the real-world cost and cost-effectiveness of this programme, and potential cost-effectiveness if implemented by the Ministry of Health (MoH).
Methods Costs (patient-level microcosting) and treatment outcomes were collected from the MSF prospective cohort study in Dawei, Myanmar. A Markov model was used to assess cost-effectiveness of the programme compared with no HCV treatment from a health provider perspective. Estimated lifetime and healthcare costs (in 2017 US1250). We evaluated cost-effectiveness with updated quality-assured generic DAA prices and potential cost-effectiveness of a proposed simplified treatment protocol with updated DAA prices if implemented by the MoH.
Results From November 2016 to October 2017, 122 with HIV/HCV-coinfected patients were treated with DAAs (46% with cirrhosis), 96% (n=117) achieved sustained virological response. Mean treatment costs were 1971 (with cirrhosis), with DAA drugs being the largest contributor to cost. Compared with no treatment, the program was cost-effective (ICER 488/DALY averted). A simplified treatment protocol delivered by the MoH could be cost-effective if associated with similar outcomes (ICER $316/DALY averted).
Conclusions Using MSF programme data, the DAA treatment programme for HCV among HIV-coinfected individuals is cost-effective in Myanmar, and even more so with updated DAA prices. A simplified treatment protocol could enhance cost-effectiveness if further rollout demonstrates it is not associated with worse treatment outcomes
The Marine Microbial Eukaryote Transcriptome Sequencing Project (MMETSP): Illuminating the Functional Diversity of Eukaryotic Life in the Oceans through Transcriptome Sequencing
Microbial ecology is plagued by problems of an abstract nature. Cell sizes are so small and population sizes so large that both are virtually incomprehensible. Niches are so far from our everyday experience as to make their very definition elusive. Organisms that may be abundant and critical to our survival are little understood, seldom described and/or cultured, and sometimes yet to be even seen. One way to confront these problems is to use data of an even more abstract nature: molecular sequence data. Massive environmental nucleic acid sequencing, such as metagenomics or metatranscriptomics, promises functional analysis of microbial communities as a whole, without prior knowledge of which organisms are in the environment or exactly how they are interacting. But sequence-based ecological studies nearly always use a comparative approach, and that requires relevant reference sequences, which are an extremely limited resource when it comes to microbial eukaryotes
Alcohol expectancies and inhibition conflict as moderators of the alcohol-unprotected sex relationship: event-level findings from a daily diary study among individuals living with HIV in Cape Town, South Africa
Literature from sub-Saharan Africa and elsewhere supports a global association between alcohol and HIV risk. However, more rigorous studies using multiple event-level methods find mixed support for this association, suggesting the importance of examining potential moderators of this relationship. The present study explores the assumptions of alcohol expectancy theory and alcohol myopia theory as possible moderators that help elucidate the circumstances under which alcohol may affect individuals' ability to use a condom. Participants were 82 individuals (58 women, 24 men) living with HIV who completed daily phone interviews for 42 days which assessed daily sexual behavior and alcohol consumption. Logistic generalized estimating equation models were used to examine the potential moderating effects of inhibition conflict and sex-related alcohol outcome expectancies. The data provided some support for both theories and in some cases the moderation effects were stronger when both partners consumed alcohol.

High rates of unprotected sex occurring among HIV-positive individuals in a daily diary study in South Africa: the role of alcohol use
Objectives: The objectives of this study were to assess the prevalence of unprotected sex and to examine the association between
alcohol consumption before sex and unprotected sex among HIVpositive individuals in Cape Town, South Africa.
Methods: For 42 days, daily phone interviews assessed daily sexual behavior and alcohol consumption. Logistic and Poisson generalized estimating equation models were used to examine associations between alcohol consumption before sex and subsequent unprotected sex.
Results: During the study which yielded 3035 data points, 58 HIVpositive women and 24 HIV-positive men drank an average of 6.13
drinks when they drank and reported 4927 sex events, of which 80.17% were unprotected. More than half (58%) of unprotected sex
events were with HIV-negative partners or with partners with unknown HIV status. Extrapolating from the data using likelihood of
infection per act estimates, we calculated that an estimated 2.95 incident HIV infections occurred during the study. Drinking alcohol
before sex by the female partner or the male partner, or by both partners increased the proportion and number of subsequent
unprotected sex events. However, these associations held only when the quantity of alcohol consumed corresponded to moderate or higher risk drinking.
Conclusions: Among HIV positive individuals, engaging in moderate or higher risk drinking before sex increases the likelihood and rate of unprotected sex. Prevention efforts need to address reducing alcohol-involved unprotected sex among HIV-positive persons.
