Abstract
Internationally, HIV-related stigma and crystal methamphetamine (meth) use have been described as barriers to treatment adherence among gay, bisexual, and other men who have sex with men (gbMSM). Crystal meth use has been increasing among gbMSM in the Metropolitan Area of Mexico City (MAMC). Therefore, this study aimed to determine the association between HIV-related stigma and HIV treatment adherence among gbMSM who use crystal meth in the MAMC. This study was undertaken as part of an exploratory study of crystal meth use in the MAMC. The data were collected from September to December 2021 through an encrypted online survey. Participants (n = 89) were gbMSM adults living with HIV who reported crystal meth use in the past month that were recruited through an online snowball sampling. The online survey included questions about HIV treatment adherence, sexual behaviors, the Alcohol, Smoking, and Substance Involved Screening Test, and the HIV-Related Stigma Mechanisms Scale. Logistic regression analyses assessed the association between HIV-related stigma and HIV treatment adherence. The multivariate logistic regression model showed that, controlling for health insurance [adjusted odds ratio (AOR) = 0.13; 95% confidence intervals (CI) = 0.02-0.59] and educational level (AOR = 0.16; 95% CI = 0.02-0.88), non-adherence to HIV treatment was independently associated with higher HIV-related stigma (AOR = 1.06; 95% CI = 1.01-1.12). Public health policies must include HIV-related stigma and substance use in treating gbMSM with HIV.

Abstract
OBJECTIVE This study assessed the magnitude of risky sexual practices and associated factors among adult people living with HIV (PLHIV) attending antiretroviral clinics in public hospitals in Kembata Tembaro Zone, southern Ethiopia. DESIGN A cross-sectional study was conducted. SETTING A hospital-based study was conducted among adult PLHIV in the Kambata Tambaro Zone, southern Ethiopia. PARTICIPANTS 300 men and women aged 15 years and older who had been receiving HIV/AIDS care and support in four public hospitals participated in this study. STUDY OUTCOME Risky sexual practice was the study outcome. It was defined based on responses to four items: multiple sexual partnerships, casual sex, consistent condom use and sex under the influence of alcohol. Risky sexual practice was defined based on a 'yes' response to any of the four items. RESULTS Of the adult PLHIV who were sexually active in the 6 months preceding the survey, 75.7% (95% CI: 70.5% to 80.2%) engaged in at least one risky sexual practice, with 3.3% (95% CI: 1.8% to 6.1%) engaged in three or more. A positive attitude towards condom use and being on antiretroviral therapy for over 10 years were correlated with low odds of risky sexual practices. There was a higher likelihood of risky sexual behaviour among those who kept their HIV status secret and did not bring up using a condom before sexual contact. Whereas, those with a positive attitude towards condom use had a reduced risk of engaging in risky sexual practices. CONCLUSION A considerable proportion of adult PLHIV engage in risky sexual practices. Efforts directed at removing barriers to disclosing HIV status to partners and promoting condom use discussion among sexual partners could reduce the burden of risky sexual practices and the onward transmission of HIV.

Differences in adoption of COVID-19 pandemic related preventive behaviour by viral load suppression status among people living with HIV during the first wave of the pandemic. BMC Res Notes 2023; 16:90. [PMID: 37231488 PMCID: PMC10212221 DOI: 10.1186/s13104-023-06363-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 05/19/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND Adherence to antiretroviral therapy and COVID-19 preventive behaviours among people living with HIV during the pandemic has received little attention in the literature. To address this gap in knowledge, the present study assessed the associations between viral load, adherence to antiretroviral therapy and the use of COVID-19 prevention strategies during the first wave of the COVID-19 pandemic. This was a secondary analysis of data generated through an online survey recruiting participants from 152 countries. Complete data from 680 respondents living with HIV were extracted for this analysis. RESULTS The findings suggest that detectable viral load was associated with lower odds of wearing facemasks (AOR: 0.44; 95% CI:0.28-0.69; p < 0.01) and washing hands as often as recommended (AOR: 0.64; 95% CI: 0.42-0.97; p = 0.03). Also, adherence to the use of antiretroviral drugs was associated with lower odds of working remotely (AOR: 0.60; 95% CI: 0.38-0.94; p = 0.02). We found a complex relationship between HIV positive status biological parameters and adherence to COVID-19 preventive measures that may be partly explained by risk-taking behaviours. Further studies are needed to understand the reasons for the study findings.

Abstract
Human immunodeficiency virus (HIV) selectively targets and destroys the infection-fighting CD4+ T-lymphocytes of the human immune system, and has a life cycle that encompasses binding to certain cells, fusion to that cell, reverse transcription of its genome, integration of its genome into the host cell DNA, replication of the HIV genome, assembly of the HIV virion, and budding and subsequent release of free HIV virions. Once a host is infected with HIV, the host’s ability to competently orchestrate effective and efficient immune responses against various microorganisms, such as viral infections, is significantly disrupted. Without modern antiretroviral therapy (ART), HIV is likely to gradually destroy the cellular immune system, and thus the initial HIV infection will inexorably evolve into acquired immunodeficiency syndrome (AIDS). Generally, HIV infection in a patient has an acute phase, a chronic phase, and an AIDS phase. During these three clinical stages, patients are found with relatively specific levels of viral RNA, develop rather distinctive immune conditions, and display unique clinical manifestations. Convergent research evidence has shown that hepatitis B virus (HBV) co-infection, a common cause of chronic liver disease, is fairly common in HIV-infected individuals. HBV invasion of the liver can be facilitated by HIV infection at each clinical stage of the infection due to a number of contributing factors, including having identical transmission routes, immunological suppression, gut microbiota dysbiosis, poor vaccination immune response to hepatitis B immunization, and drug hepatotoxicity. However, there remains a paucity of research investigation which critically describes the influence of the different HIV clinical stages and their consequences which tend to favor HBV entrenchment in the liver. Herein, we review advances in the understanding of the mechanisms favoring HBV infection at each clinical stage of HIV infection, thus paving the way toward development of potential strategies to reduce the prevalence of HBV co-infection in the HIV-infected population.

Abstract
Knowledge gaps remain in the understanding of HIV disease establishment and progression. Scientists continue to strive in their endeavor to elucidate the precise underlying immunopathogenic mechanisms of HIV-related disease, in order to identify possible preventive and therapeutic targets. A useful tool in the quest to reveal some of the enigmas related to HIV infection and disease is the single-cell sequencing (scRNA-seq) technique. With its proven capacity to elucidate critical processes in cell formation and differentiation, to decipher critical hematopoietic pathways, and to understand the regulatory gene networks that predict immune function, scRNA-seq is further considered to be a potentially useful tool to explore HIV immunopathogenesis. In this article, we provide an overview of single-cell sequencing platforms, before delving into research findings gleaned from the use of single cell sequencing in HIV research, as published in recent literature. Finally, we describe two important avenues of research that we believe should be further investigated using the single-cell sequencing technique.

Abstract
CONTEXT Although viral suppression rates have recently increased among people with HIV, specific populations still experience disparities in health outcomes, a priority in the national response to end the HIV epidemic. PURPOSE The end+disparities ECHO Collaborative, a quality improvement initiative among HIV providers in the United States from June 2018 to December 2019, created virtual communities of practice to measurably increase viral suppression rates in populations disproportionately affected by HIV: men who have sex with men of color, Black/African American and Latina women, youth aged 13 to 24 years, and transgender people. METHODS Participating Ryan White HIV/AIDS Program-funded providers prioritized their improvement efforts to focus on one target population and joined virtual affinity sessions with other providers focused on that population for guidance by subject matter experts and exchanges with peer providers. During 9 submission cycles, providers reported their viral suppression data for the preceding 12 months. MAIN OUTCOME MEASURES The principal outcome measures were changes in viral suppression rates among 4 target populations and changes in viral suppression gaps compared with the rest of HIV-infected patients served by the same agency. RESULTS A total of 90 providers were included in the data analyses with an average of 110 775 reported patients, out of which 19 442 represented the targeted populations. The average viral suppression rates for agency-selected populations increased from 79.2% to 82.3% (a 3.9% increase), while the remaining caseload increased at a lower rate from 84.9% to 86.1% (a 1.4% increase). The viral suppression gap was reduced from 5.7% to 3.8%, a 33.5% reduction. Improvements were found across all target populations. CONCLUSIONS The collaborative demonstrated improved health outcomes and reductions in HIV-related health disparities, moving toward ending the HIV epidemic. The model of utilizing low-cost videoconferencing technologies to create virtual communities of learning is well suited to mitigate other disease-related disparities, nationally and abroad.

Abstract
Despite the benefits achieved by the widespread availability of modern antiretroviral therapy (ART), HIV RNA integration into the host cell genome is responsible for the creation of latent HIV reservoirs, and represents a significant impediment to completely eliminating HIV infection in a patient via modern ART alone. Several methods to measure HIV reservoir size exist; however, simpler, cheaper, and faster tools are required in the quest for total HIV cure. Over the past few years, measurement of HIV-specific antibodies has evolved into a promising option for measuring HIV reservoir size, as they can be measured via simple, well-known techniques such as the western blot and enzyme-linked immunosorbent assay (ELISA). In this article, we re-visit the dynamic evolution of HIV-1-specific antibodies and the factors that may influence their levels in the circulation of HIV-positive individuals. Then, we describe the currently-known relationship between HIV-1-specific antibodies and HIV reservoir size based on study of data from contemporary literature published during the past 5 years. We conclude by highlighting current trends, and discussing the individual HIV-specific antibody that is likely to be the most reliable antibody for potential future utilization for quantification of HIV reservoir size.

Abstract
Young heterosexual men have low uptake of HIV prevention and treatment services and represent an important key population that may require novel strategies. We recruited 1271 heterosexual men, 12 years and older from socializing venues such as "shebeens", transport hubs, "spaza" shops, and community centers in rural KwaZulu-Natal, South Africa. Participants completed a questionnaire and were tested for HIV serostatus. Generalized estimating equations (GEE) with exchangeable covariance structure estimated factors independently associated with prevalent HIV infection. Median age was 25 years [Interquartile range (IQR) 21-29]. HIV prevalence was 15.5% [95% confidence interval (CI) 11.0-21.9] and increased significantly by age. Factors associated with higher odds of HIV infection were being 25 years and older [adjusted odds ratio (aOR) 4.82, 95% CI 3.47-6.69; p < 0.001), not completing high school (aOR 1.60, 95% CI 1.39-1.85; p < 0.001), not using condoms at first sex (aOR 1.43, 95% CI 1.20-1.70; p < 0.001), consuming alcohol (aOR 1.63, 95% CI 1.15-2.31; p = 0.006) or substances (aOR 1.37, 95% CI 1.31-1.44; p < 0.001), and absence of medical circumcision (aOR 2.05, 95% CI 1.71-2.44; p < 0.001). Risk was lower among those testing for HIV in last 12 months (aOR 0.54, 95% CI 0.36-0.80; p = 0.002). Greater effort is needed to implement innovative programs within settings that are easily accessible and where heterosexual men are likely to be.

Abstract
Although Vietnam has promoted the utilisation of highly active antiretroviral therapy (HAART) towards HIV elimination targets, adherence to treatment has remained under-investigated. We aimed to describe high-risk behaviours and clinical characteristics by adherence status and to identify the factors associated with non-adherence. We included 426 people living with HIV (PLWH) currently or previously involved in HAART. Most participants were men (75.4%), young (33.6 years), with low income and low education levels. Non-adherent PLWH (11.5%) were more likely to have a larger number of sex partners (p-value = 0.053), sex without condom use (p-value = 0.007) and not receive result at hospital or voluntary test centre (p-value = 0.001). Multiple logistic regression analysis showed that demographic (education levels), sexual risk behaviours (multiple sex partners and sex without using condom) and clinical characteristics (time and facility at first time received HIV-positive result) were associated with HAART non-adherence. There are differences in associated factors between women (education levels and place of HIV testing) and men (multiple sex partners). Gender-specific programs, changing risky behaviours and reducing harms among PLWH may benefit adherence. We highlight the need to improve the quantity and quality of HIV/AIDS services in Vietnam, especially in pre- and post-test counselling, to achieve better HAART adherence, working towards ending AIDS in 2030.

Abstract
Introduction Combination antiretroviral therapy (cART) improves outcomes for people living with HIV (PLWH) but requires adherence to daily dosing. Suboptimal adherence results in reduced treatment effectiveness, increased costs, and greater risk of resistance and onwards transmission. Treatment with long-acting (LA), injection-based ART administered by healthcare professionals (directly observed therapy (DOT)) eliminates the need for adherence to daily dosing and may improve clinical outcomes. This study reports the cost-effectiveness of the cabotegravir plus rilpivirine LA regimen (CAB+RPV LA) and models the potential impact of LA DOT therapies. Methods Parameterisation was performed using pooled data from recent CAB+RPV LA Phase III trials. The analysis was conducted using a cohort-level hybrid decision-tree and state-transition model, with states defined by viral load and CD4 cell count. The efficacy of oral cART was adjusted to reflect adherence to daily regimens from published data. A Canadian health service perspective was adopted. Results CAB+RPV LA is predicted to be the dominant intervention when compared to oral cART, generating, per 1,000 patients treated, lifetime cost-savings of $1.5 million, QALY and life-year gains of 107 and 138 respectively with three new HIV cases averted. Conclusions Economic evaluations of LA DOTs need to account for the impact of adherence and HIV transmission. This study adds to the existing literature by incorporating transmission and using clinical data from the first LA DOT regimen. Providing PLWH and healthcare providers with novel modes of ART administration, enhancing individualisation of treatment, may facilitate the achievement of UNAIDS 95-95-95 objectives.

Abstract
There is a strong association between HIV-related stigma (HS) and health-related quality of life among people living with HIV/AIDS, yet few studies, to date, have examined mediators of this link. This study examined the mediating role of antiretroviral medication adherence (MA) on association between HS and HRQoL. Respondents were 969 people living with HIV/AIDS (PLWH) (628 males and 341 females, Mean age = 35.55, years), conveniently drawn from four hospital facilities in Enugu and Ebonyi States of Nigeria. Data were collected using HIV Stigma Scale, Morisky Medical Adherence Scale, and Patient Reported Outcome Quality of Life-HIV. Data were analysed using the Hayes PROCESS macro for SPSS which uses a regression-based, path-analytical framework. Results showed that HS across dimensions (personalised stigma, disclosure concern, concern about people's attitude and negative self-image) were negatively associated with MA (r = -.16; p < .001, r = -.13; p < .00, r = -.22; p < .001 and r = -.21; p < .001, respectively) HRQoL. MA was positively associated with HRQoL (r = . 24; p < .001). MA mediated HS-HRQoL association. These findings suggest that stigma associated with HIV/AIDS is associated with poor adherence to active antiretroviral therapy (ART) treatment regimen, which can result in poor health and treatment outcome among PLWH. The findings may be helpful in improving HRQoL among PLWH.

Abstract
Combination Antiretroviral Therapy (cART) in single-tablet regimens (STR) is a simplification strategy that can potentially improve medication adherence and clinical outcomes. We conducted a retrospective cohort study of 1206 patients using efavirenz, tenofovir and lamivudine in multiple-tablet regimen who switched to the STR containing the same active ingredients in a southeast metropolis in Brazil. We measured adherence using the proportion of days covered (PDC≥95%) and evaluated this outcome before and after the switch using paired non-parametric statistics. Additionally, we used group-based trajectory modeling to identify adherence patterns to cART for each period and evaluate the migration behavior of patients between the trajectory groups. We observed a 14% increase in the proportion of adherent patients after switching to STR and a 6.2% increase in the proportion of patients with CD4 count>500 cells/μl (p < 0.001), without changes in viral load outcomes. We identified four adherence trajectories in each period. Most patients (60%, n = 722) migrated towards a group with better adherence trajectory or remained in the trajectory group with the highest probability of adherence after the switch. Our findings suggest that the implementation of the STR had a positive impact on adherence and CD4 count. This may potentially improve virologic outcomes later on treatment.

Abstract
Social stigma is linked to improper HIV treatment adherence, but how stigma impairs adherence outcomes is poorly understood. This study included 93 people living with HIV in the United States who participated in focus groups or one-on-one interviews regarding how stigma might affect medication management. Latent content analysis and constant comparative techniques of participant responses that were produced three thematic groupings that described how participants (a) orient to HIV stigma, (b) manage HIV stigma in ways that directly impair treatment adherence, and (c) manage HIV stigma in ways that may indirectly impair adherence. These findings illustrate the need to understand how patients orient to HIV stigma when prescribing medications and the complications that are inherent to such assessments. In addition, these findings provide a simple framework for organizing the different ways in which stigma management strategies may disrupt treatment adherence. Conceptually, these findings also offer a paradigm shift to extent theories on disclosure and concealment, in which only disclosure has been cast as an active process. These findings demonstrate how concealment is far from a passive default, often requiring enormous effort. Ultimately, these findings may guide intervention programs that help to entirely eliminate HIV by promoting optimized counseling and subsequent treatment adherence.

Abstract
Background Delay to start antiretroviral therapy (ART) and nonadherence compromise the health and wellbeing of people living with HIV (PLWH), raise the cost of care and increase risk of transmission to sexual partners. To date, interventions to improve adherence to ART have had limited success, perhaps because they have failed to systematically elicit and address both perceptual and practical barriers to adherence. The primary aim of this study is to determine the efficacy of the Supporting UPtake and Adherence (SUPA) intervention. Methods This study comprises 2 phases. Phase 1 is an observational cohort study, in which PLWH who are ART naïve and recommended to take ART by their clinician complete a questionnaire assessing their beliefs about ART over 12 months. Phase 2 is a randomised controlled trial (RCT) nested within the observational cohort study to investigate the effectiveness of the SUPA intervention on adherence to ART. PLWH at risk of nonadherence (based on their beliefs about ART) will be recruited and randomised 1:1 to the intervention (SUPA intervention + usual care) and control (usual care) arms. The SUPA intervention involves 4 tailored treatment support sessions delivered by a Research Nurse utilising a collaborative Cognitive Behavioural Therapy (CBT) and Motivational Interviewing (MI) approach. Sessions are tailored to individual needs and preferences based on the individual patient’s perceptions and practical barriers to ART. An animation series and intervention manual have been developed to communicate a rationale for the personal necessity for ART and illustrate concerns and potential solutions. The primary outcome is adherence to ART measured using Medication Event Monitoring System (MEMS). Three hundred seventy-two patients will be sufficient to detect a 15% difference in adherence with 80% power and an alpha of 0.05. Costs will be compared between intervention and control groups. Costs will be combined with the primary outcome in cost-effectiveness analyses. Quality adjusted life-years (QALYs) will also be estimated over the follow-up period and used in the analyses. Discussion The findings will enable patients, healthcare providers and policy makers to make informed decisions about the value of the SUPA intervention. Trial registration The trial was retrospectively registered 21/02/2014, ISRCTN35514212.

Abstract
Depression can result in poor adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV), and social support can help mitigate the negative relationship. However, little is known about how depression and social support synergistically influence ART adherence over time. The current study aims to explore longitudinal associations between them and examine which sources of social support can play a mediating role between depression and ART adherence over time. A randomized controlled clinical trial was conducted between 2013 and 2016 in Guangxi, China. The study sample was composed of 319 PLHIV who were randomized into control condition and provided data at baseline and at least one of the six follow-ups. The results revealed negative associations of depression with ART adherence over time, and a mediating effect of perceived support from spouse/partner or children. Interventions to promote ART adherence should focus on strengthening PLHIV's relationships with their spouse/partner and children, promoting collaborative provider-patient relationships, and enhancing peer support among PLHIV.

Abstract
Food insecurity, internalized HIV stigma, and depressive symptoms are independently associated with poor HIV outcomes. Food insecurity, stigma, and depression may be interrelated among women living with HIV (WLHIV). We hypothesized that food insecurity would be independently associated with internalized stigma and depressive symptoms among WLHIV in the United States (US), and would partially account for associations between stigma and depressive symptoms. We tested hypotheses using regression models and partial correlation analysis with cross-sectional data among 1317 WLHIV from the Women's Interagency HIV Study. In adjusted models, greater food insecurity was associated with internalized HIV stigma and depressive symptoms (all p < 0.05), exhibiting dose-response relationships. Food insecurity accounted for 23.2% of the total shared variance between depressive symptoms and internalized stigma. Food insecurity is associated with depressive symptoms and internalized HIV stigma among US WLHIV, and may play a role in the negative cycle of depression and internalized stigma.

Abstract
Viral suppression, a critical component of HIV care, is more likely when individuals initiate antiretroviral therapy (ART) early in disease progression and maintain optimal levels of adherence to ART regimens. Although several studies have documented the negative association of depressive symptoms with ART adherence, less is known about how depressed mood relates to intentional versus unintentional lapses in adherence as well as the mechanisms underlying this association. The purpose of the current study was to examine the association of depressive symptoms with ART adherence, assessed as a multidimensional construct. Secondarily, this study conducted preliminary indirect path models to determine if medication self-efficacy could explain the depressed mood-adherence relationship. Depressive symptoms were not associated with 95% ART taken, self-reported viral load, deliberate adjustments to ART regimens or skipped ART doses. However, the indirect association of depressive symptoms via decrements in medication self-efficacy was significant for 95% ART taken, self-reported viral load and skipped ART doses, but not deliberate changes to ART regimens. In this sample of HIV-positive outpatients, there is evidence to support medication self-efficacy as a potential mechanism underlying the association between depressive symptoms and ART adherence. Additional longitudinal studies are needed to formally examine medication taking self-efficacy as a mediator.

Abstract
Safe sexual behaviors and anti-retroviral use help prevent HIV transmission. In this cross-sectional study, we assessed correlates of anti-retroviral (ART) status and transmission risk (a constructed variable) among a convenience sample of n = 1041 HIV-positive women (pre-intervention) enrolled in an evidence-based intervention at four CBOs. Multinomial logistic regression models were used. Younger women and those diagnosed with HIV in the last 5 years more often reported that they had not been prescribed ART. Self-reported non-adherence to ART was less frequently reported among women who were older, had a higher HIV knowledge, and those with attitudes/beliefs supportive of condom use. The highest-risk transmission group (condomless sex with HIV-negative/unknown partner and not prescribed or non-adherent to ART) was associated with younger age, attitudes/beliefs less supportive of condom use, and low self-efficacy discussing condom use. Our findings inform HIV prevention efforts among similar populations of HIV-positive women enrolled in interventions at CBOs.

Abstract
In Peru, the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW). Multiple studies correlate alcohol use disorders (AUDs) with risky sexual behaviors among Peruvian MSM. Qualitative research was used to inform a clinical trial on the acceptability of medication-assisted therapies to assist management of AUDs and improve antiretroviral therapy (ART) adherence among MSM/TGW in Peru. Three focus groups involving HIV-infected or HIV-uninfected MSM/TGW ( n = 26) with AUDs (AUDIT ≥ 8) were transcribed, translated from Spanish into English, and analyzed using thematic content analysis. Despite having an AUD, participants considered themselves "social" drinkers, minimized their drinking behaviors, and differed about whether or not alcohol problems could be treated. Participants expressed skepticism about medication for treating AUDs. Three concepts emerged as necessary components of a treatment program for alcohol problems: cost, family support, and the potential to drink less alcohol without attaining total abstinence. This study reveals important areas of education to increase potential acceptability of a medication for treating AUDs among MSM/TGW. Given the social conditions and knowledge base of the participants, medication-assisted therapies using naltrexone may be a beneficial strategy for MSM with AUDs.

Abstract
This study identified prevalence and correlates of HIV-associated dementia (HAD) among people living with HIV (PLWHA) in Ho Chi Minh City, Vietnam. Four hundred PLWHA completed a self-report questionnaire and were interviewed by a trained researcher to assess HAD using the International HIV Dementia Scale (IHDS). Clinical information concerning HIV treatment was also extracted from medical records. The results indicate the prevalence of probable HAD based on IHDS score <10.5 was 39.8% (95% confidence interval [CI]: 35.0%-44.5%). Probable HAD was significantly higher among female, older PLWHA and among those with low education level (≤ primary school), moderate level of adherence to HIV medication and HIV stage 3. Those PLWHA with depressive symptoms also had higher odds of having probable HAD (odds ratio = 3.23, 95% CI: 2.05-5.11). These findings underscore the importance of early HAD screening and appropriate referral for further assessment and management of PLWHA especially those with higher risk of HAD.

Abstract
The objective of the Savings, Agriculture, Governance, and Empowerment for Health (SAGE4Health) study was to evaluate the impact of a large-scale multi-level economic and food security intervention on health outcomes and HIV vulnerability in rural Malawi. The study employed a quasi-experimental non-equivalent control group design to compare intervention participants (n = 598) with people participating in unrelated programs in distinct but similar geographical areas (control, n = 301). We conducted participant interviews at baseline, 18–, and 36–months on HIV vulnerability and related health outcomes, food security, and economic vulnerability. Randomly selected households (n = 1002) were interviewed in the intervention and control areas at baseline and 36 months. Compared to the control group, the intervention led to increased HIV testing (OR 1.90; 95 % CI 1.29–2.78) and HIV case finding (OR = 2.13; 95 % CI 1.07–4.22); decreased food insecurity (OR = 0.74; 95 % CI 0.63–0.87), increased nutritional diversity, and improved economic resilience to shocks. Most effects were sustained over a 3-year period. Further, no significant differences in change were found over the 3-year study period on surveys of randomly selected households in the intervention and control areas. Although there were general trends toward improvement in the study area, only intervention participants’ outcomes were significantly better. Results indicate the intervention can improve economic and food security and HIV vulnerability through increased testing and case finding. Leveraging the resources of economic development NGOs to deliver locally-developed programs with scientific funding to conduct controlled evaluations has the potential to accelerate the scientific evidence base for the effects of economic development programs on health.

Abstract
Shortages of human resources for treating HIV/AIDS (HRHA) are a fundamental barrier to reaching universal antiretroviral treatment (ART) coverage in developing countries. Previous studies suggest that recruiting HRHA to attain universal ART coverage poses an insurmountable challenge as ART significantly increases survival among HIV-infected individuals. While new evidence about ART's prevention benefits suggests fewer infections may mitigate the challenge, new policies such as treatment-as-prevention (TasP) will exacerbate it. We develop a mathematical model to analytically study the net effects of these countervailing factors. Using South Africa as a case study, we find that contrary to previous results, universal ART coverage is achievable even with current HRHA numbers. However, larger health gains are possible through a surge-capacity policy that aggressively recruits HRHA to reach universal ART coverage quickly. Without such a policy, TasP roll-out can increase health losses by crowding out sicker patients from treatment, unless a surge capacity exclusively for TasP is also created.

Abstract
Gay men with diagnosed HIV can adopt a number of strategies to reduce the risk of transmitting HIV to others, although research has typically focussed on condom use. Interviews with 42 HIV-positive gay men who reported recent engagement in anal intercourse without condoms explored their awareness of sexual risk and their perceptions of non-condom-related strategies to reduce it. In articulating men's ambivalence for strategies that can only reduce the risk of transmission, rather than eliminating, the findings have implications for the consideration and integration of new biomedical interventions to reduce the likelihood of HIV transmission.

A retrospective and prospective analysis of trading sex for drugs or money in women substance abuse treatment patients. Drug Alcohol Depend 2016; 162:182-9.

Abstract
BACKGROUND Trading sex for drugs or money is common in substance abuse treatment patients, and this study evaluated prevalence and correlates of this behavior in women with cocaine use disorders initiating outpatient care. In addition, we examined the relation of sex trading status to treatment response in relation to usual care versus contingency management (CM), as well as predictors of continued involvement in sex trading over a 9-month period. METHODS Women (N=493) recruited from outpatient substance abuse treatment clinics were categorized according to histories of sex trading (n=215, 43.6%) or not (n=278). RESULTS Women with a history of trading sex were more likely to be African American, older and less educated, and they had more severe employment problems and were more likely to be HIV positive than those without this history. Controlling for baseline differences, both groups responded equally to substance abuse treatment in terms of retention and abstinence outcomes. Fifty-four women (11.3%) reported trading sex within the next nine months. Predictors of continued involvement in trading sex included a prior history of such behaviors and achieving less abstinence during treatment. Each additional week of abstinence during treatment was associated with a 16% reduction in the likelihood of trading sex over the follow-up. CONCLUSIONS Because over 40% of women receiving community-based treatment for cocaine use disorders have traded sex for drugs or money and more than 10% persist in the behavior, more intensive and directed approaches toward addressing this HIV risk behavior are recommended.

Abstract
Background Collective health behavior often demonstrates counter-intuitive dynamics, sometimes resisting interventions designed to produce change, or even producing effects that are in the opposite direction than intended by the intervention, e.g. lowering infectivity resulting in increased infections. At other times collective health behavior exhibits sudden large-scale change in response to small interventions or change in the environment, a phenomenon often called “tipping.” I hypothesize that these seemingly very different phenomena can all be explained by the same dynamic, a type of collective resilience. Methods I compared two simple agent-based models of interactions in networks: a public health behavior game, in which individuals decide whether or not to adopt protective behavior, and a microbial-level game, in which three different strains of bacteria attack each other. I examined the type of networks and other conditions that support a dynamic balance, and determined what changes of conditions will tip the balance. Results Both models show lasting dynamic equilibrium and resilience, resulting from negative feedback that supports oscillating coexistence of diversity under a range of conditions. In the public health game, health protection is followed by free-riding defectors, followed by a rise in infection, in long-lasting cycles. In the microbial game, each of three strains takes turns dominating. In both games, the dynamic balance is tipped by lowering the level of local clustering, changing the level of benefit, or lowering infectivity or attack rate. Lowering infectivity has the surprising effect of increasing the numbers of infected individuals. We see parallel results in the microbial game of three bacterial strains, where lowering one strain’s attack rate (analogous to lowering infectivity) increases the numbers of the restrained attacker, a phenomenon captured by the phrase, “the enemy of my enemy is my friend.” Conclusions Collective behavior often shows a dynamic balance, resulting from negative feedback, supporting diversity and resisting change. Above certain threshold conditions, the dynamic balance is tipped towards uniformity of behavior. Under a certain range of conditions we see “hydra effects” in which interventions to lower attack rate or infectivity are self-defeating. Simple models of collective behavior can explain these seemingly disparate dynamics.

Abstract
The objective of this study was to examine the extent of unprotected sex among patients already established in HIV-medical care and their associated factors. Sexually active patients who were receiving antiretroviral therapy (ART) from five public hospitals in Trang province, Southern Thailand, were interviewed. Of 279 studied patients, 37.3% had unprotected sex in the prior 3 months and 27.2% did not disclose their serostatus to sexual partners. The median duration interquartile range (IQR) of using ART was 47 (27-60) months and 26.7% were non-adherent to ART (i.e., taking less than 95% of the prescribed doses). More than one-third had the perception that ART use would protect against HIV transmission even with unprotected sex. About 36.6% reported that they were unaware of their current CD4 counts and nearly one-third did not receive any safe sex counseling at each medical follow-up. After adjustment for potential confounders, non-adherence to ART and HIV-nondisclosure were strongly associated with an increase in the risk of unprotected sex with the adjusted odds ratio (aOR) of 5.03 (95% CI 2.68-9.44) and 3.89 (95% CI 1.57-9.61), respectively. In contrast, the risk for engaging in unprotected sex was less likely among patients having a negative-serostatus partner (aOR = 0.30; 95% CI 0.12-0.75), a longer duration of the use of ART (aOR = 0.98; 95%CI 0.97-0.99) and an unawareness of their current CD4 levels (aOR = 0.54; 95% CI 0.30-0.99). To maximize the benefits from ART, there should be a bigger emphasis on the "positive prevention" program and more efforts are needed to target the population at risk for unprotected sex. Strategies to encourage adherence to ART and for disclosure of serostatus are also required.

Abstract
BACKGROUND Despite advances in treatment of people living with HIV, morbidity and mortality remains unacceptably high in sub-Saharan Africa, largely due to parallel epidemics of poverty and food insecurity. METHODS/DESIGN We conducted a pilot cluster randomized controlled trial (RCT) of a multisectoral agricultural and microfinance intervention (entitled Shamba Maisha) designed to improve food security, household wealth, HIV clinical outcomes and women's empowerment. The intervention was carried out at two HIV clinics in Kenya, one randomized to the intervention arm and one to the control arm. HIV-infected patients >18 years, on antiretroviral therapy, with moderate/severe food insecurity and/or body mass index (BMI) <18.5, and access to land and surface water were eligible for enrollment. The intervention included: 1) a microfinance loan (~$150) to purchase the farming commodities, 2) a micro-irrigation pump, seeds, and fertilizer, and 3) trainings in sustainable agricultural practices and financial literacy. Enrollment of 140 participants took four months, and the screening-to-enrollment ratio was similar between arms. We followed participants for 12 months and conducted structured questionnaires. We also conducted a process evaluation with participants and stakeholders 3-5 months after study start and at study end. DISCUSSION Baseline results revealed that participants at the two sites were similar in age, gender and marital status. A greater proportion of participants at the intervention site had a low BMI in comparison to participants at the control site (18% vs. 7%, p = 0.054). While median CD4 count was similar between arms, a greater proportion of participants enrolled at the intervention arm had a detectable HIV viral load compared with control participants (49% vs. 28%, respectively, p < 0.010). Process evaluation findings suggested that Shamba Maisha had high acceptability in recruitment, delivered strong agricultural and financial training, and led to labor saving due to use of the water pump. Implementation challenges included participant concerns about repaying loans, agricultural challenges due to weather patterns, and a challenging partnership with the microfinance institution. We expect the results from this pilot study to provide useful data on the impacts of livelihood interventions and will help in the design of a definitive cluster RCT.

Abstract
This article responds to a recent 'controversy study' in Global Public Health by de Camargo et al. directed at three randomised controlled trials (RCTs) of male circumcision (MC) for HIV prevention. These trials were conducted in three countries in sub-Saharan Africa (SSA) and published in 2005 and 2007. The RCTs confirmed observational data that had accumulated over the preceding two decades showing that MC reduces by 60% the risk of HIV infection in heterosexual men. Based on the RCT results, MC was adopted by global and national HIV policy-makers as an additional intervention for HIV prevention. Voluntary medical MC (VMMC) is now being implemented in 14 SSA countries. Thus referring to MC for HIV prevention as 'debate' and viewing MC through a lens of controversy seems mistaken. In their criticism, de Camargo et al. misrepresent and misinterpret current science supporting MC for HIV prevention, omit previous denunciations of arguments similar to theirs, and ignore evidence from ongoing scientific research. Here we point out the flaws in three areas de Camargo et al. find contentious. In doing so, we direct readers to growing evidence of MC as an efficacious, safe, acceptable, relatively low-cost one-off biomedical intervention for HIV prevention.

Abstract
BACKGROUND The HIV epidemic continues unabated in the USA, with men who have sex with men (MSM) being most frequently infected. PURPOSE The purpose of this study is to understand the biological and behavioral risk factors associated with increased HIV transmission efficiency, which is HIV transmission risk behavior in the context of uncontrolled HIV replication or intercurrent sexually transmitted infections. METHODS Participants were 201 HIV-infected MSM who received their primary care at an HIV ambulatory care center in Boston. Logistic regression models were conducted to determine factors associated with engaging in behavior associated with potentially amplified transmission. RESULTS In the final model, heavy alcohol use (AOR, 3.27; 95 % CI 1.37-7.79), as well as stimulant drug use (crystal meth, crack, or other cocaine; AOR, 3.00; CI 1.32-6.84), having at least a college degree (OR, 2.74; CI, 1.15-6.54), and decreased duration of HIV infection (OR, 0.91; CI, 0.85-0.97) were each uniquely associated with enhanced HIV transmission behavior. CONCLUSIONS HIV primary care providers should routinely assess patients for potential HIV transmission behaviors, particularly those who are younger and more recently diagnosed with HIV, who drink alcohol heavily, and who use any nonprescription drugs, particularly stimulants, in order to decrease the spread of HIV.

Abstract
In the era of highly active antiretrovirals, people living with HIV (PLWH) have resumed sexual activity in the context of longer and healthier lives, and thus the chances of transmitting the HIV virus, as well as the potential to be re-infected also increase. HIV treatment optimism has been found to be associated with sexual risk behaviors among PLWH in different settings. A cross sectional survey was conducted to examine the relationship between treatment optimism, safer sex burnout and consistent condom use as well as variables associated with treatment optimism in a sample of PLWH on antiretrovirals (ARVs) in Rio de Janeiro, Brazil (n = 604). Seventy-two percent of participants always used a condom in the last 6 months. Homosexual, bisexual, transexual persons were less likely to use condoms consistently than heterosexuals (AOR .58 CI .42-.78). Those who were treatment optimistic (AOR .46 CI .25-.88) were more likely not use a condom consistently in the past 6 months, as were participants who reported safer sex burnout (AOR .58 CI .36-.90). Sexual orientation, safer sex burnout, and lower education levels were significantly associated with higher treatment optimism in multivariate analysis. Study findings highlight the need to address psychosocial factors such as treatment optimism and safer sex burnout associated with lower consistent condom use among PLWH in Rio de Janeiro, Brazil.

Abstract
Non-adherence to safer sex and non-adherence to ART can each have adverse health consequences for HIV-infected individuals and their sex partners, but little is known about the association of these behaviors with each other. This "dual risk" has potential negative public health consequences since non-adherence can lead to the development of resistant virus that can then be transmitted to sex partners. Among participants in the Multi-site Adherence Collaboration in HIV we examined, at study baseline, the association between the frequency of unprotected sex (assessed by self-report) and ART adherence (assessed by Medication Event Monitoring System, Aardex) among the sexually active participants in the five studies (N = 459) that collected sexual risk behavior. The bivariate association between sexual risk behaviors and ART adherence was assessed by Pearson correlations; subsequently regression analyses were used to evaluate the role of demographic characteristics, depression and substance use in explaining the "dual risk" outcome (sexual risk and non-adherence). Among participants who had been sexually active, more unprotected anal/vaginal sex was weakly associated with poorer ART adherence (r = -0.12, p = 0.01 for the overall sample). Further analysis showed this association was driven by the heterosexual men in the sample (r = -0.29, p < 0.001), and was significant only for this group, and not for gay/bisexual men or for women (heterosexual and homosexual). Neither substance use nor depression accounted for the association between sexual risk and ART adherence. HIV-infected heterosexual men who are having difficulty adhering to ART are also more likely to engage in risky sexual behaviors and therefore may benefit from counseling about these risk behaviors. We must identify procedures to screen for these risk behaviors and develop interventions, appropriately tailored to specific populations and identified risk factors, that can be integrated into routine clinical care for people living with HIV. This will become increasingly important in the context of wider access to treatment globally, including new recommendations for ART initiation earlier in a patients' disease course (e.g., "Test and Treat" paradigms).

Abstract
Background Poverty and lack of a predictable, stable source of food are two fundamental determinants of ill health, including HIV/AIDS. Conversely, episodes of poor health and death from HIV can disrupt the ability to maintain economic stability in affected households, especially those that rely on subsistence farming. However, little empirical research has examined if, and how, improvements in people’s economic status and food security translate into changes in HIV vulnerability. Methods In this paper, we describe in detail the methods and protocol of an academic-NGO collaboration on a quasi-experimental, longitudinal study of the mechanisms and magnitude of the impact of a multilevel economic and food security program (Support to Able-Bodied Vulnerable Groups to Achieve Food Security; SAFE), as implemented by CARE. Primary outcomes include HIV vulnerability (i.e., HIV risk behaviors, HIV infection), economic status (i.e., income, household assets) and food security (including anthropometric measures). We recruited participants from two types of areas of rural central Malawi: traditional authorities (TA) selected by CARE to receive the SAFE program (intervention group) and TAs receiving other unrelated CARE programming (controls). In the intervention TAs, we recruited 598 program participants (398 women, 200 men) and interviewed them at baseline and 18- and 36-month follow-ups; we interviewed 301 control households. In addition, we conducted random surveys (n = 1002) in the intervention and control areas with a 36-month assessment interval, prior to and after implementation of SAFE. Thus, we are examining intervention outcomes both in direct SAFE program participants and their larger communities. We are using multilevel modeling to examine mediators and moderators of the effects of SAFE on HIV outcomes at the individual and community levels and determine the ways in which changes in HIV outcomes feed back into economic outcomes and food security at later interviews. Finally, we are conducting a qualitative end-of-program evaluation consisting of in-depth interviews with 90 SAFE participants. Discussion In addition to examining pathways linking structural factors to HIV vulnerability, this research will yield important information for understanding the impact of a multilevel environmental/structural intervention on HIV, with the potential for other sustainable long-term public health benefits.

Abstract
OBJECTIVES To compare the advantages to patients and to programmes between fixed-dose combination (FDC) antiretroviral therapy and separate tablet regimens. METHODS Three electronic databases and two conference abstract sites were searched from inception to 01 March 2013 without geographical, language or date limits. Studies were included if they reported data on clinical outcomes, patient-reported outcomes and programme-related outcomes that could be related to pill burden for adult and adolescent patients on ART. For the primary outcomes of adherence and virological suppression, relative risks and 95% confidence intervals were calculated, and these were pooled using random effects meta-analysis. RESULTS Twenty-one studies including information on 27,230 subjects were reviewed. Data from randomised trials showed better adherence among patients receiving FDCs than among patients who did not (relative risk 1.10, 95%CI 0.98-1.22); these findings were consistent with data from observational cohorts (RR 1.17, 95% CI 1.07-1.28). There was also a tendency towards greater virological suppression among patients receiving FDCs in randomised trials (RR 1.04, 95%CI 0.99-1.10) and observational cohort studies (RR 1.07, 95% CI 0.97-1.18). In all studies reporting patient preference, FDCs were preferred. The overall quality of the evidence was rated as low. CONCLUSIONS Fixed-dose combinations appear to offer multiple advantages for programmes and patients, particularly with respect to treatment adherence.

Abstract
Both antiretroviral treatment interruption (TI) and cessation have been strongly discouraged since 2006. We describe the incidence, duration, and risk factors for TI and loss-to-follow-up (LTFU) rates across 13 countries. All 4689 adults (76% men) in two large HIV cohorts in Australia and Asia commencing combination antiretroviral therapy (ART) to March 2010 were included. TI was defined by ART cessation >30 days, then recommencement, and loss to follow-up (LTFU) by no visit since 31 March 2009 and no record of death. Survival analysis and Poisson regression methods were used. With median follow-up of 4.4 years [interquartile range (IQR):2.1-6.5], TI incidence was 6.7 per 100 person years (PY) (95% CI:6.1-7.3) pre-2006, falling to 2.0 (95% CI:1.7-2.2) from 2006 (p<0.01). LTFU incidence was 3.5 per 100 PY (95% CI:3.1-3.9) pre-2006, and 4.1 (95% CI:3.5-4.9) from 2006 (p=0.22). TIs accounted for 6.4% of potential time on ART pre-2006 and 1.2% from 2006 (p<0.01), and LTFU 4.7% of potential time on ART pre-2006 and 6.6% from 2006 (p<0.01). Median TI duration was 163 (IQR: 75-391) days pre-2006 and 118 (IQR: 67-270) days from 2006 (p<0.01). Independent risk factors for the first TI were: Australia HIV Observational Database participation; ART initiation pre-2006; ART regimens including stavudine and didanosine; three nucleoside analogue reverse transcriptase inhibitors; ≥7 pills per day; and ART with food restrictions (fasting or with food). In conclusion, since 2006, 7.8% of patients had significant time off treatment, which has the potential to compromise any 'test and treat' policy as during the interruption viral load will rebound and increase the risk of transmission.

Abstract
Providers do not predict reliably which of their HIV-positive patients are having difficulty adhering to antiretroviral therapy (ART). The transtheoretical, or stages of change model, may be a useful tool to help providers identify patients who are having difficulty with ART adherence. The objective of the current study was to determine the relationship between stages of change and ART adherence among patients who were actively taking ART. Data from a randomized trial of a provider-focused intervention were used to examine the relationship between the stages of change and adherence, measured using electronic monitoring devices in the 30 days following the stages of change assessment. Individuals were eligible for inclusion if they were taking ART and had detectable plasma viral load (HIV-RNA). Repeated measures analysis of covariance was used to determine the impact of stages of change on adherence after controlling for potential confounders. The sample of 137 participants was 22% female, 48% white, 28% African-American, with a mean age of 42 years. Fifty-eight percent reported sex with a man as an HIV risk factor, while 13% reported sex with a woman, 14% reported injecting drugs and 15% reported other risk factors. In adjusted models, those in earlier stages of change (i.e., contemplation and preparation) had significantly lower adherence (-9.8%, p=0.04) compared to those in the action and maintenance phases. No demographic characteristics predicted adherence. The stages of change model may function as a screening tool for clinicians to discover patients at-risk of lower adherence.

Abstract
OBJECTIVE Locate persons living with HIV (PLWH) presumed lost to follow-up (LTFU), and assist them with partner services and linkage to HIV-related care. DESIGN Locate and facilitate re-engagement in care for PLWH-LTFU in New York City (NYC), with longitudinal follow-up using HIV surveillance registry. SETTINGS HIV care facilities and communities in NYC. PATIENTS PLWH, reported in the NYC HIV surveillance registry, who had a NYC care provider and residential address at last report in the registry. Presumed-LTFU was defined as having no CD4+ or viral load during the most recent 9 months during the study period July 2008-December 2010. INTERVENTION Case-workers conducted public health investigation to locate PLWH presumed-LTFU and offered them assistance with partner and linkage-to-care services. MAIN OUTCOME MEASURES Results of partner and linkage-to-care services, and reasons for LTFU. RESULTS From July 2008 to December 2010, 797 PLWH presumed-LTFU were prioritized for investigation; 14% were never located. Of the 689 located, 33% were current to care, 5% had moved or were incarcerated, 2% had died, and 59% (409) were verified to be LTFU. Once located, 77% (315/409) accepted clinic appointments, and 57% (232/409) returned to care. Among the 161 who provided reasons for LTFU, the most commonly reported was 'felt well' (41%). CONCLUSIONS Health department case-workers helped more than half PLWH-LTFU re-engage in HIV medical care. HIV prevention strategies must include efforts to re-engage PLWH-LTFU in care, for treatment consideration under current treatment guidelines to improve their clinical status and decrease transmission risk.

Abstract
Despite the HIV "test-and-treat" strategy's promise, questions about its clinical rationale, operational feasibility, and ethical appropriateness have led to vigorous debate in the global HIV community. We performed a systematic review of the literature published between January 2009 and May 2012 using PubMed, SCOPUS, Global Health, Web of Science, BIOSIS, Cochrane CENTRAL, EBSCO Africa-Wide Information, and EBSCO CINAHL Plus databases to summarize clinical uncertainties, health service challenges, and ethical complexities that may affect the test-and-treat strategy's success. A thoughtful approach to research and implementation to address clinical and health service questions and meaningful community engagement regarding ethical complexities may bring us closer to safe, feasible, and effective test-and-treat implementation.

Abstract
OBJECTIVE We conducted a study to identify gender differences in factors associated with the first episode of non-adherence in the 12 months following the first antiretroviral prescription. METHODS A concurrent prospective study of patients initiating antiretroviral therapy in Brazil was conducted from 2001-2002. The self-reported measurement of adherence was defined as an intake of less than 95% of the prescribed number of doses. Only the first occurrence of non-adherence was considered in this analysis. All analyses were stratified by gender. A Cox proportional hazard model was used to estimate the risk of non-adherence, and the time to non-adherence was estimated using the Kaplan-Meier method. RESULTS The cumulative incidence of non-adherence was 34.6% (29.7% and 43.9% among men and women, respectively; p=0.010). Marital status (being married or in stable union; p=0.022), alcohol use in the month prior to the baseline interview (p=0.046), and current tobacco use (p=0.005) increased the risk of non-adherence among female participants only, whereas a self-reported difficulty with the antiretroviral treatment was associated with non-adherence in men only. For both men and women, we found that a longer time between the HIV test and first antiretroviral therapy prescription (p=0.028) also presented an increased risk of non-adherence. CONCLUSIONS In this cohort study, the incidence of non-adherence was 1.5 times greater among women compared to men. Our results reinforce the need to develop interventions that account for gender differences in public referral centers. Additionally, we emphasize that, to achieve and maintain appropriate adherence levels, it is important to understand the barriers to seeking and utilizing health care services.

Abstract
The HIV Prevention Trials Network (HPTN) 052 study, which showed the effectiveness of antiretroviral treatment in reducing HIV transmission, has been hailed as a "game changer" in the fight against HIV, prompting calls for scaling up treatment as prevention (TasP). However, it is unclear how TasP can be financed, given flat-lining support for global HIV programs. We assess whether TasP is indeed a game changer or if comparable benefits are obtainable at similar or lower cost by increasing coverage of medical male circumcision (MMC) and antiretroviral treatment (ART) at CD4 <350/μL. We develop a new mathematical model and apply it to South Africa, finding that high ART coverage combined with high MMC coverage provides approximately the same HIV incidence reduction as TasP, for $5 billion less over 2009-2020. MMC outperforms ART significantly in cost per infection averted ($1,096 vs. $6,790) and performs comparably in cost per death averted ($5,198 vs. $5,604). TasP is substantially less cost effective at $8,375 per infection and $7,739 per death averted. The prevention benefits of HIV treatment are largely reaped with high ART coverage. The most cost-effective HIV prevention strategy is to expand MMC coverage and then scale up ART, but the most cost-effective HIV-mortality reduction strategy is to scale up MMC and ART jointly. TasP is cost effective by commonly used absolute benchmarks but it is far less cost effective than MMC and ART. Given South Africa's current annual ART spending, the $5 billion in savings offered by MMC and ART over TasP in the next decade, for similar health benefits, challenges the widely hailed status of TasP as a game changer.

Abstract
The purpose of this study was to assess the prevalence of, and the factors associated with HIV testing and pre- and post-test counselling (PPTC) in Colombia. Cross-sectional data from the National Health Survey carried out during 2007 were analysed. Data were gathered from records of 29,760 individuals between the ages of 18 and 69 from the main regions of the country. Only 19.7% of the sample had taken an HIV test. Men, people with no education, those not affiliated with the health-care system, residents of rural areas and those aged older than 65 were less likely to have been tested for HIV; 42% of those tested did not receive pre-test counselling and 56.9% received no report of the results. Considering the low prevalence of HIV testing among the Colombian population, it is necessary to design and apply guidelines for HIV screening in all health-care settings and to conduct targeted testing in high-risk sub-populations. A national norm of PPTC in those who undergo HIV testing should be examined.

Abstract
The contribution of bipolar disorder (BD), a prevalent serious mental illness characterized by impulsivity and mood instability, to antiretroviral (ART) and psychiatric medication adherence among HIV-infected (HIV+) individuals is unknown. We examined medication adherence among 44 HIV+/BD+ persons as compared to 33 demographically- and medically-comparable HIV+/BD- persons. Classification of adherent (≥ 90%) or non-adherent (<90%) based on proportion of correctly taken doses over 30 days was determined using electronic medication monitoring devices. HIV+/BD+ persons were significantly less likely to be ART adherent (47.7%) as compared to HIV+/BD- (90.9%) persons. Within the HIV+/BD+ group, mean psychiatric medication adherence was significantly worse than ART medication adherence, although there was a significant correlation between ART and psychiatric adherence levels. Importantly, 30-day ART adherence was associated with plasma virologic response among HIV+/BD+ individuals. Given the high overlap of HIV and BD, and the observed medication adherence difficulties for these persons, specialized adherence improvement interventions are needed.

Abstract
Objective This study aims to investigate the time pattern of inconsistence condom use (ICU) during the first year of antiretroviral therapy (ART) and its relationship with treatment adherence in naïve HIV-infected adult patients. Methods Data collection was nested within a longitudinal trial on HIV treatment. ICU was defined as reporting to have “never”, “sometimes” or “nearly always” used condoms with one’s main or casual partner(s) - either HIV-negative or of unknown HIV status in the three previous months. Adherence was defined as taking 100% of their ART prescribed doses in the 4 days before the visit and “not having interrupted treatment”, even once, for more than two consecutive days during the 4 previous weeks. Mixed logistic regression was used to study the relationship between adherence and ICU. Results Among the 459 patients enrolled, 212 (46%) during 334 visits reported to have had sexual intercourse at least once with their partner(s) – either HIV-negative or of unknown HIV status- during the first 12 months of ART. The proportion of ICU was 76%, 50% and 59% at month 0 (M0), month 6 (M6) and month 12 (M12), while 60% and 66% of patients were ART-adherent at M6 and M12, respectively. After adjustment for the frequency of sexual activity, type of sexual partner(s), perceived social class and desire for a child, patients adherent to ART were less likely to report ICU when compared with baseline (AOR [95% CI]: 0.38 [0.19–0.76]; P = 0.006). Conclusions Adherence to ART is associated with a lower risk of ICU but this result needs to be interpreted carefully. As adherence behaviors are not only determined by problems with the healthcare systems but also by social barriers encountered by patients in their daily life, counseling should not only be ART adherence-centered but also patient-centered, including sexual risk minimization and psychosocial support.

Abstract
PURPOSE OF REVIEW This review explores the policy implications of findings from the HIV Prevention Trials Network (HPTN 052) treatment as prevention (TasP) study. RECENT FINDINGS To date, the potential of antiretrovirals to prevent sexual transmission of HIV by infected persons has been grounded in observational cohort, ecological, mathematical modeling, and meta-analytic studies. HPTN 052 represents the first randomized controlled trial to test the secondary prevention benefit of HIV transmission using antiretroviral treatment in largely asymptomatic persons with high CD4 cell counts. SUMMARY The US National HIV/AIDS Strategy has among its key goals the reduction of incident HIV infections, improved access to quality care and associated outcomes, and the reduction in HIV-associated health disparities and inequities. HPTN 052 demonstrates that providing TasP, in combination with other effective prevention strategies offers the promise of achieving these life-saving goals. But HPTN 052 also highlights the need for cautious optimism and underscores the importance of addressing current gaps in the HIV prevention, treatment, and care continuum in order for 'TasP' strategies to achieve their full potential. Among these are necessary improvements in the capacity to expand HIV testing, facilitate effective linkage and retention in care, and improve treatment initiation, maintenance, and virus suppression.

Abstract
HAART has increased the life expectancy of HIV-infected individuals significantly. Optimal adherence to HAART results in viral suppression and immune recovery in the majority of HIV-infected persons. Data from the early HAART era suggest that adherence levels of greater than 95% are necessary to achieve and maintain virological suppression. However, the optimal threshold of adherence required to maximize the pharmacological benefits of contemporary antiretroviral regimens, particularly in the virologically suppressed patient, is unknown. This review examines new data on the role of adherence in the late HAART era, focusing on virological, immunological and epidemiological aspects. We begin with a discussion of the impact of adherence on viral dynamics and immunological parameters in the virologically suppressed patient. We then review the importance of adherence in emerging antiretroviral treatment strategies. Finally, we summarize accumulating data on the role of antiretroviral adherence in the prevention of HIV transmission. Taken together, the data reviewed reinforce the critical importance of adherence in the management of HIV infection in the late HAART era.
