Abstract
INTRODUCTION In people living with HIV, active and latent tuberculosis (TB) coinfections are associated with immune activation that correlate with HIV progression and mortality. We investigated the effect of initiating antiretroviral therapy (ART) during acute (AHI), recent (RHI), or chronic HIV infection (CHI) on CD4/CD8 ratio normalization and associated factors, the impact of latent TB infection treatment, and prior/concomitant TB diagnosis at the time of ART initiation. METHODS We included sex with men and transgender women individuals initiating ART with AHI, RHI and CHI between 2013 and 2019, from a prospective cohort in Brazil. We compared time from ART initiation to the first normal CD4/CD8 ratio (CD4/CD8 ≥1) using Kaplan-Meier curves and multivariable Cox proportional hazards models. Sociodemographic and clinical variables were explored. Variables with P -values <0.20 in univariable analyses were included in multivariable analyses. RESULTS Five hundred fifty participants were included, 11.8% classified as AHI and 6.4% as RHI, 46.7% with CHI-CD4 cell counts ≥350 cells/mm 3 and 35.1% with CHI-CD4 cell counts <350 cells/mm 3 . Time to normalization was shortest among AHI patients, followed by RHI and CHI individuals with higher baseline CD4. In the multivariable model, AHI was associated with a six-fold increased likelihood of achieving a CD4/CD8 ratio ≥1 (hazard ratio [HR]: 6.03; 95% confidence interval [CI]: 3.70 to 9.82; P < 0.001), RHI with HR: 4.47 (95% CI: 2.57 to 7.76; P < 0.001), and CHI CD4 ≥350 cells/mm 3 with HR: 1.87 (95% CI: 1.24 to 2.84; P = 0.003). Latent TB infection treatment was significantly associated with a higher likelihood of the outcome (HR: 1.79; 95% CI: 1.22 to 2.62; P = 0.003). Previous history or concomitant active TB at ART initiation was associated with a lower likelihood of the outcome (HR: 0.41; 95% CI: 0.16 to 1.02; P = 0.054). CONCLUSIONS Initiating ART early during AHI may offer an opportunity to mitigate immune damage. Efforts to implement HIV diagnosis and ART initiation during AHI are critical to amplify ART benefits.

Abstract
We investigate the association between nativity status (U.S.- vs foreignborn) and viral suppression among women of color (WOC) with HIV (HIV +) and whether this association was modified by education and housing. METHODS Data were from 549 HIV + WOC, who participated in the Health Resources and Services Administration-funded WOC Initiative 2009-2013. We used generalized estimating equation models to quantify the association between the respondents' nativity status and viral suppression. RESULTS After adjusting for covariates, foreign-born WOC were 2.2 times (95% confidence interval: 1.25, 3.85) more likely to achieve viral suppression than U.S.-born WOC. This association was not modified by education or housing status. CONCLUSIONS Despite facing barriers to care, foreign-born WOC were more likely to achieve viral suppression than U.S.-born WOC. Programs aiming to end the HIV epidemic and reduce HIV disparities in the U.S. should consider these findings as they provide a more nuanced understanding of HIV + WOC.

Abstract
PURPOSE OF REVIEW Long-acting formulations of antiretrovirals have the potential to reshape the treatment paradigm for HIV infection. Emerging evidence demonstrates efficacy and safety of two drug regimens for the treatment of HIV infection. This review focuses on recent advances with long-acting cabotegravir and rilpivirine administered intramuscularly every 4 weeks for the treatment of HIV infection in virologically suppressed patients. RECENT FINDINGS Despite the development of complete, orally administered single tablet regimens with improved efficacy, side effects, tolerability, with an improved drug interaction potential, patients still have challenges adhering to daily oral therapy. Psychological factors including HIV stigma contribute to patient's ability to adhere to treatment. Newer nonoral treatment regimens may improve adherence, patient satisfaction and limit HIV stigma. SUMMARY A two-drug intramuscular regimen of cabotegravir and rilpivirine has advanced through phase 3 clinical development. Results from studies assessing safety, virologic, pharmacologic, and drug interactions have been completed. Larger efficacy studies have demonstrated noninferiority of switching virologically suppressed patients from a three drug daily oral regimen to a two-drug intramuscular regimen administered Q4W with long-term data to 160 weeks demonstrating durability of treatment response.

Abstract
Introduction Few studies have estimated complete antiretroviral therapy (ART) adherence following HIV infection since the advent of the new ART guidelines in 2012. This study determined the prevalence and influence of sociodemographic, behavioral, and clinical factors on complete ART adherence among people living with HIV (PLWH) receiving medical care in Houston/Harris County, Texas. Methods Data from the Houston Medical Monitoring Project survey collected from 2009 to 2014 among 1073 participants were used in this study. The primary outcome evaluated was combined adherence, defined as complete, partial, and incomplete combined adherence based on three ART adherence types—dose, schedule, and instruction adherence. The duration living since initial HIV diagnosis was classified as <5, 5–10 and >10 years. Rao–Scott Chi-square test and multivariable proportional-odds cumulative logit regression models were employed to identify the sociodemographic, behavioral, and clinical characteristics of complete combined adherence among the three groups of PLWH living with HIV infection. Results More than one-half (54.4%) of PLWH had complete, 37.4% had partial, and 8.3% had incomplete combined adherence. Among these PLWH, 52.2% had been infected with HIV for >10 years, and 26.5% and 21.4% were infected for <5 years and 5–10 years, respectively. PLWH who were diagnosed <5 and 5–10 years were two times (aOR=1.71, 95% CI=1.13–2.57; aOR=1.69, 95% CI=1.10–2.59; respectively) more likely to experience complete combined adherence than those with >10 years of infection. Multiple sociodemographic, behavioral, and clinical characteristics were significantly associated with complete adherence and varied by the duration of HIV infection. Conclusion Measures of adherence should include all adherence types (dose, schedule, instruction), as utilizing a single adherence type will overestimate adherence level in PLWH receiving medical care. Intervention efforts to maintain adherence should target recently infected PLWH, while those aimed at improving adherence should focus on longer infected PLWH.

Abstract
Background Long-acting injectable antiretroviral therapy (LA ART) has been shown to be non-inferior to daily oral ART, with high patient satisfaction and preference to oral standard of care in research to date, and has recently been approved for use in the United States and Europe. This study examined the perspectives of health care providers participating in LA ART clinical trials on potential barriers and solutions to LA ART roll-out into real world settings. Methods This analysis draws on two data sources: (1) open-ended questions embedded in a structured online survey of 329 health care providers participating in the ATLAS-2 M trial across 13 countries; and (2) in-depth interviews with 14 providers participating in FLAIR/ ATLAS/ATLAS-2 M trials in the United States and Spain. Both assessments explored provider views and clinic dynamics related to the introduction of LA ART and were analyzed using thematic content analysis. The Consolidated Framework for Implementation Research (CFIR) was drawn on as the conceptual framework underpinning development of a model depicting study findings. Results Barriers and proposed solutions to LA ART implementation were identified at the individual, clinic and health system levels. Provider perceptions of patient level barriers included challenges with adhering to frequent injection appointments and injection tolerability. Proposed solutions included patient education, having designated staff for clinic visit retention, and clinic flexibility with appointment scheduling. The main provider concern was identifying appropriate candidates for LA ART; proposed solutions focused on patient provider communication and decision making. Clinic level barriers included the need for additional skilled individuals to administer injections, shifts in workflow as demand increases and the logistics of cold-chain storage. Proposed solutions included staff hiring and training, strategic planning around workflow and logistics, and the possibility of offering injections in other settings, including the home. Health system level barriers included cost and approvals from national regulatory bodies. Potential solutions included governments subsidizing treatment, ensuring cost is competitive with oral ART, and offering co-pay assistance. Conclusions Results suggest the importance of multi-level support systems to optimize patient-provider communication and treatment decision-making; clinic staffing, workflow, logistics protocols and infrastructure; and cost-related factors within a given health system.

Abstract
Long-acting injectable antiretroviral therapy (LA ART) may be an alternative for people living with HIV (PLHIV) with adherence challenges or who prefer not to take pills. Using in-depth interviews, this study sought to understand the experiences of PLHIV (n = 53) participating in Phase 3 LA ART trials in the United States and Spain. The most salient consideration when contemplating LA ART was its clinical efficacy; many participants reported wanting to ensure that it worked as well as daily oral ART, including with less frequent dosing (every 8 versus 4 weeks). While injection side effects were often reported, most participants felt that regimen benefits outweighed such drawbacks. Participants described the main benefit of LA ART as the "freedom" it afforded both logistically and psychosocially, including through reduced HIV stigma. Findings highlight the importance of patient-provider communication related to weighing potential benefits and side effects and the continued need to address HIV stigma.

Abstract
BACKGROUND Socioeconomic and demographic statuses are associated with adherence to the treatment of patients with several chronic diseases. However, there is a controversy regarding their impact on adherence among HIV/AIDS patients. Thus, we performed a systematic review of the evidence regarding the association of socioeconomic and demographic statuses with adherence to antiretroviral therapy (ART) among HIV/AIDS patients. METHODS The PubMed database was used to search and identify studies concerning about socioeconomic and demographic statuses and HIV/AIDS patients. Data were collected on the association between adherence to ART and varies determinants factors of socioeconomic (income, education, and employment/occupation) and socio-demographic (sex and age). FINDINGS From 393 potentially-relevant articles initially identified, 35 original studies were reviewed in detail, which contained data that were helpful in evaluating the association between socioeconomic/ demographic statuses and adherence to ART among HIV patients. Two original research study has specifically focused on the possible association between socioeconomic status and adherence to ART. Income, level of education, and employment/occupational status were significantly and positively associated with the level of adherence in 7 studies (36.8%), 7 studies (28.0%), and 4 studies (23.5%) respectively out of 19, 25, and 17 studies reviewed. Sex (being male), and age (per year increasing) were significantly and positively associated with the level of adherence in 5 studies (14.3%), and 9 studies (25.7%) respectively out of 35 studies reviewed. However, the determinant of socioeconomic and demographic statuses was not found to be significantly associated with adherence in studies related to income 9(47.4%), education 17(68.0%), employment/ occupational 10(58.8%), sex 27(77.1%), and age 25(71.4%). CONCLUSION The majority of the reviewed studies reported that there is no association between socio- demographic and economic variables and adherence to therapy. Whereas, some studies show that age of HIV patients (per year increasing) and sex (being male) were positively associated with adherence to ART. Among socio-economic factors, the available evidence does not provide conclusive support for the existence of a clear association with adherence to ART among HIV patients. There seems to be a positive trend between socioeconomic factors and adherence to ART in some of the reviewed studies.

Abstract
CONTEXT Human immunodeficiency virus (HIV) incidence and prevalence in the United States are characterized by significant disparities by race/ethnicity. National HIV care goals, such as boosting to 90% the proportion of persons whose HIV is diagnosed and increasing to 80% the proportion of persons living with diagnosed HIV who are virally suppressed, will likely reduce HIV incidence, but their effects on HIV-related disparities are uncertain. OBJECTIVE We sought to understand by race/ethnicity how current HIV care varies, the level of effort required to achieve national HIV care goals, and the effects of reaching those goals on HIV incidence and disparities. DESIGN Using a dynamic model of HIV transmission, we identified 2016 progress along the HIV care continuum among blacks, Hispanics, and whites/others compared with national 2020 goals. We examined disparities over time. SETTING United States. PARTICIPANTS Beginning in 2006, our dynamic compartmental model simulated the sexually active US population 13 to 64 years of age, which was stratified into 195 subpopulations by transmission group, sex, race/ethnicity, age, male circumcision status, and HIV risk level. MAIN OUTCOME MEASURE We compared HIV cumulative incidence from 2016 to 2020 when goals were reached compared with base case assumptions about progression along the HIV care continuum. RESULTS The 2016 proportion of persons with diagnosed HIV who were on treatment and virally suppressed was 50% among blacks, 56% among Hispanics, and 61% among whites/others, compared with a national goal of 80%. When diagnosis, linkage, and viral suppression goals were reached in 2020, cumulative HIV incidence fell by 32% (uncertainty range: 18%-37%) for blacks, 25% (22%-31%) for Hispanics, and 25% (21%-28%) for whites/others. Disparity measures changed little. CONCLUSIONS Achieving national HIV care goals will require different levels of effort by race/ethnicity but likely will result in substantial declines in cumulative HIV incidence. HIV-related disparities in incidence and prevalence may be difficult to resolve.

Abstract
BACKGROUND We estimated the effect of initiating virologically suppressive antiretroviral therapy (ART) during acute HIV infection versus chronic HIV infection (AHI vs. CHI) on CD4/CD8 ratio normalization. SETTING A prospective clinical cohort study. METHODS We included patients initiating ART with AHI and CHI between 2000 and 2015 and compared time from ART initiation to the first normal CD4/CD8 ratio (defined as CD4/CD8 ≥1) using Kaplan-Meier curves and multivariable Cox proportional hazards models. Patient time was censored at virologic failure, lost to follow-up, or death. We also characterized CD4, CD8, and CD4/CD8 trajectories over the first 3 years of ART. RESULTS The 1198 patients were 27% female and 60% African American, with a median age of 37 years (interquartile range 28-47) at ART initiation. The 83 AHI patients were more likely male, younger, and of white race, than CHI patients. After 2 years of suppressive ART, 70% of AHI patients achieved a normal CD4/CD8 ratio, compared to 6%-38% of CHI patients, with greater likelihood of normalization at higher baseline CD4 counts. Time to normalization was shortest among AHI patients, followed by CHI patients with higher baseline CD4. The adjusted hazard ratio for time to normalization for AHI patients compared to CHI patients with baseline CD4 >350 was 4.33 (95% CI: 3.16 to 5.93). Higher baseline CD4/CD8 ratio was also associated with time to normalization (adjusted hazard ratio 1.54; 1.46, 1.63, per 0.1 increase in ratio). CONCLUSIONS Initiating ART during AHI at higher baseline CD4 cell counts and CD4/CD8 ratios was associated with shorter time to CD4/CD8 ratio normalization.

Abstract
Despite advances in HIV antiretroviral medications, some patients do not achieve adequate medication adherence or suppressed viral load. The aim of this study was to identify the relationship between factors of impulsivity and medication non-adherence. It was hypothesized that impulsivity would have a direct association with non-adherence, after accounting for other known correlates. Participants included 322 HIV positive individuals (M age = 49, 56% male, 64% Black/African American). Impulsivity was measured using the Barratt Impulsiveness Scale-Brief (BIS-Brief). Factor analysis was conducted to determine if BIS-Brief resulted in a unidimensional or multi-factor solution. Results were suggestive of a two-factor solution: behavioral impulsivity and non-planning impulsivity. Structural equation modeling found non-planning impulsivity was associated with non-adherence (β = 0.18, p = 0.016), while no significant association was observed for behavioral impulsiveness. Results suggest that strategies related to planning for future consequences may be beneficial for impulsive persons with medication adherence difficulties.

Abstract
OBJECTIVE To estimate the prevalence of HIV drug resistance over time and identify risk factors for multiclass resistance. DESIGN Prospective clinical cohort of HIV-infected patients at the University of North Carolina. METHODS Among antiretroviral therapy (ART)-experienced patients in care 2000-2016, we estimated annual prevalences of cumulative resistance, defined as at least one major mutation by drug class. Clinical data and multiple imputation were used when genotypic data were missing, and mutations were carried forward in time. We estimated resistance odds ratios comparing characteristics of patients in care in 2016. RESULTS A total of 3682 patients contributed 23 169 person-years. Prevalence of at least one major resistance mutation, irrespective of viral suppression, peaked in 2005 with 49% (95% confidence interval 46, 52) and decreased to 38% (35, 40) in 2016. Resistance to nucleoside reverse transcriptase inhibitors, protease inhibitors, and nonnucleoside reverse transcriptase inhibitors also peaked in 2005-2007 and decreased to 28 (26, 31), 14 (12, 16), and 27% (24, 29) in 2016, respectively. In 2016, prevalence of integrase strand transfer inhibitor (INSTI) resistance was 2% (1, 3) and triple-class resistance 10% (9, 12). Over the study period, cumulative resistance was frequent among patients with detectable viremia, but uncommon among patients initiating ART post-2007. Among 1553 patients in care in 2016, ART initiation at an older age, with an INSTI, and with higher CD4 cell counts were associated with resistance to fewer or no classes. CONCLUSION Prevalence of resistance to older ART classes has decreased in the last 10 years in this clinical cohort, whereas INSTI resistance has increased but remained very low. Patients with viremia continue to have a high burden of resistance even if they initiated ART recently.

Abstract
Not taking medicine over a specific period of time-non-persistence to antiretroviral therapy (ART)-may be associated with higher HIV-viral load. However, national estimates of non-persistence among U.S. HIV patients are lacking. We examined the association between non-persistence and various factors, including sustained HIV-viral suppression (VS) stratified by adherence, and assessed reasons for non-persistence using Medical Monitoring Project (MMP) data. MMP conducts clinical and behavioral surveillance among cross-sectional representative samples of adults receiving HIV care in the U.S. We analyzed weighted MMP interview and medical record abstraction data collected between 6/2011-5/2015 from 18,423 patients self-reporting ART use. We defined non-persistence as a self-initiated decision to not take ART for ≥2 consecutive days in the past 12-months, non-adherence as missing ≥1 ART dose during the past 3-days and sustained VS as all HIV-viral loads documented in medical record during the past 12-months as undetectable or <200 copies/mL. We used Rao-Scott chi-square tests to examine the association between non-persistence and sociodemographic, behavioral, clinical, and medication-related factors. We examined the association between non-persistence and sustained VS, stratified by adherence, and present prevalence ratios (PRs) with 95% confidence intervals (CIs). Reasons for non-persistence were assessed. Overall, 7% of patients reported non-persistence. Drug use, depression and medication side effects were associated with non-persistence (P < 0.01). Non-persistence was associated with the lack of sustained VS (PR: .66, CI:63-.70); this association did not differ by adherence level. However, VS was lower among the non-persistent/adherent compared with the persistent/non-adherent [51% (CI:47-54) versus 61% (CI:36-46), P < 0.01]. The most prevalent reason for non-persistence was treatment fatigue (38%). Though few persons in HIV care reported non-persistence, our findings suggest that non-persistence is associated with lack of sustained VS, regardless of adherence. Routine screening for non-persistence during clinical appointments and counseling for those at risk for non-persistence may help improve clinical outcomes.

Abstract
OBJECTIVES Social determinants of health (SDHs) are the complex, structural, and societal factors that are responsible for most health inequities. Since 2003, the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) has researched how SDHs place communities at risk for communicable diseases and poor adolescent health. We described the frequency and types of SDHs discussed in articles authored by NCHHSTP. METHODS We used the MEDLINE/PubMed search engine to systematically review the frequency and type of SDHs that appeared in peer-reviewed publications available in PubMed from January 1, 2009, through December 31, 2014, with a NCHHSTP affiliation. We chose search terms to identify articles with a focus on the following SDH categories: income and employment, housing and homelessness, education and schooling, stigma or discrimination, social or community context, health and health care, and neighborhood or built environment. We classified articles based on the depth of topic coverage as "substantial" (ie, one of ≤3 foci of the article) or "minimal" (ie, one of ≥4 foci of the article). RESULTS Of 862 articles authored by NCHHSTP, 366 (42%) addressed the SDH factors of interest. Some articles addressed >1 SDH factor (366 articles appeared 568 times across the 7 categories examined), and we examined them for each category that they addressed. Most articles that addressed SDHs (449/568 articles; 79%) had a minimal SDH focus. SDH categories that were most represented in the literature were health and health care (190/568 articles; 33%) and education and schooling (118/568 articles; 21%). CONCLUSIONS This assessment serves as a baseline measurement of inclusion of SDH topics from NCHHSTP authors in the literature and creates a methodology that can be used in future assessments of this topic.

Abstract
BACKGROUND Despite substantial advances in the era of highly active antiretroviral therapy, HIV-positive persons are at high risk of tobacco-related disease and mortality. This study describes the prevalence and sociodemographic factors associated with current tobacco use among HIV-positive men and women 18 years and older receiving HIV care in Puerto Rico. METHODS Data from the 2009 Medical Monitoring Project (MMP) was used. A three-stage sampling design was conducted to obtain annual cross-sectional probability samples of HIV-infected adults in care. Factors associated with current tobacco use were identified using logistic regression models. All analyses were performed using STATA version 11.0. RESULTS The estimated prevalence of current cigarette use among the population was 29.0% (95%CI: 23.5%-35.2%), daily smoking was reported in 76.7% of them. Multivariate logistic regression models, showed that male drug users (injected and noninjected) were up to nine times more likely to be current smokers (OR = 9.9; 95%CI = 3.1, 31.5) as compared to nonusers. CONCLUSION Findings highlight the need for smoking cessation strategies in this population, particularly among male HIV+ drug users.

Abstract
Challenges with adherence to daily oral antiretroviral therapy (ART) among people living with HIV (PLHIV) have stimulated development of injectable long-acting (LA) regimens. We conducted 39 in-depth interviews with participants and providers in a Phase IIb study (LATTE-2) evaluating an injectable LA regimen in the U.S. and Spain. Interviews exploring participant and provider attitudes and experiences with LA versus oral ART were audiotaped, transcribed and analyzed using thematic content analysis. Participants described the convenience of LA injections versus daily pills and emotional benefits such as minimized potential for HIV disclosure and eliminating the "daily reminder of living with HIV." Providers recognized benefits but cautioned that LA candidates still need to adhere to clinic visits for injections and raised questions around ongoing clinical management. LA was seen as preferable to daily oral ART among PLHIV. Further research is needed regarding appropriate candidates, including with women and "non-adherent" populations across settings.

Abstract
BACKGROUND Comparisons of antiretroviral therapy (ART) prescription and viral suppression among people in HIV care across US metropolitan areas are limited. Medical Monitoring Project, 2011-2013, data were used to describe and compare associations between sociodemographics and ART prescription and viral suppression for persons receiving HIV care. SETTING Chicago, Los Angeles County (LAC), Philadelphia, and San Francisco in the United States. METHODS Bivariate and multivariable methods were used. RESULTS The proportion of patients prescribed ART (91%-93%) and virally suppressed (79%-88%) was consistent although more persons were virally suppressed in San Francisco compared with the other areas, and a smaller proportion was virally suppressed in Philadelphia compared with Chicago. In the combined cohort, persons aged 30-49 years were less likely than persons 50+ (adjusted prevalence ratio (aPR) -0.97, confidence interval (CI): 0.94 to 0.99); persons reporting non-injection drug use were less likely than non-users (aPR = 0.94, CI: 0.90 to 0.98); and Hispanics were more likely than whites (aPR - 1.04, CI: 1.01 to 1.08) to be prescribed ART. Blacks (aPR = 0.93; CI: 0.87 to 0.99) and homeless persons (aPR = 0.87; CI: 0.80 to 0.95) were less likely to be virally suppressed in the combined cohort. In LAC, persons aged 30-49 years were less likely than those 50+ to be prescribed ART (aPR = 0.94, CI: 0.90 to 0.98). Younger persons (18-29) (aPR = 0.77; CI: 0.60 to 0.99) and persons with less than a high school education (aPR = 0.80; CI: 0.67 to 0.95) in Philadelphia, blacks (aPR = 0.90; CI: 0.83 to 0.99) and men who have sex with women only (aPR = 0.89; CI: 0.80 to 0.99) in Chicago, and homeless individuals in LAC (aPR = 0.80; CI: 0.67 to 0.94) were less likely to be virally suppressed. CONCLUSION Data highlight the need to increase ART prescription to achieve viral suppression among younger persons, noninjection drug users, blacks, and homeless persons in US metropolitan areas and underscores the importance of region-specific strategies for affected subgroups.

Abstract
Background Antiretroviral (ARV) adherence of ≥ 95% is recommended for suppressing HIV. However, studies have shown that the ≥ 95% recommended level is rarely achieved. Objective This cross-sectional community-based study sought to assess factors contributing to ARV drug adherence among adults living with HIV or AIDS. Setting The study was conducted in a rural community in Machakos County, Kenya. Methods The questions used for the study were adapted from the Patient Medicine Adherence Questionnaire (PMAQ), a tool grounded in the Health Belief Model. Adherence to ARV was measured using self-reports and pill counts. The perception social support was measured with a 5-point Likert scale, whereas the type and the number of side effects experienced were recorded using ‘yes’ and ‘no’ questions. We used the chi-square test to test associations and binary logistic regression to assess factors explaining dose adherence to ARV. Results The levels of adherence of 86% using self-reports were significantly higher (p < 0.001) than the pill count of 58.6%. The immediate family was rated high in providing social support (3.7 ± 0.6) followed by social support groups (3.1 ± 0.8). A binary logistic regression analysis was conducted to predict ARV adherence (adherent, non-adherent) using social support, side effects and marital status as explanatory variables. The Wald criterion demonstrated that marital status (p = 0.019) and burden of side effects (p ≤ 0.001) made a significant contribution to the prediction of ARV adherence. Conclusion The burden of side effects and being a divorcee are primary predictors of ARV adherence.

Abstract
Effective antiretroviral therapy (ART) reduces plasma HIV RNA viral load (VL) to undetectable levels and its effectiveness depends on consistent adherence. Consistent adherence and use of safe sex practices may substantially decrease the risk of HIV transmission. We sought to explore the potential association between self-reported nonadherence to ART and engaging in unsafe sexual practices capable of transmitting HIV. Using clinical and audio computer-assisted self-interview data from the prospective HIV Outpatient Study from 2007 to 2014, we assessed the frequency of self-reported ART nonadherence during the three days prior to the survey among HIV-infected persons in care and factors associated with self-reported ART nonadherence. Of 1729 patients included in this analysis (median age = 48 years, 74.3% men who have sex with men), 17% were nonadherent, 15% had a detectable VL, and 42% reported condomless anal or vaginal sex in the past six months. In multivariable analysis, self-reported nonadherence was independently associated with younger age (adjusted odds ratio [aOR] 0.8 per additional ten years, [95% CI] 0.7-1.0), non-Hispanic black race/ethnicity (aOR 1.9; 95% CI 1.4-2.6 versus white), public health insurance (aOR 1.6, 95% CI 1.2-2.3 compared with private), survey date in 2011-2014 versus 2007-2010 (aOR 0.7, 95% CI 0.5-0.9), CD4 cell count ≥ 500 versus < 200 cells/mm3 (aOR 0.3, 95% CI 0.2-0.5), greater number of ART regimen doses (aOR 1.6, 95% CI 1.3-2.2), and binge drinking (aOR 1.4, 95% CI, 1.1-1.9). In this analysis, self-reported nonadherence was not associated with engaging in condomless sex.

Mechanisms for the Negative Effects of Internalized HIV-Related Stigma on Antiretroviral Therapy Adherence in Women: The Mediating Roles of Social Isolation and Depression.

Abstract
BACKGROUND Internalization of HIV-related stigma may inhibit a person's ability to manage HIV disease through adherence to treatment regimens. Studies, mainly with white men, have suggested an association between internalized stigma and suboptimal adherence to antiretroviral therapy (ART). However, there is a scarcity of research with women of different racial/ethnic backgrounds and on mediating mechanisms in the association between internalized stigma and ART adherence. METHODS The Women's Interagency HIV Study (WIHS) is a multicenter cohort study. Women living with HIV complete interviewer-administered questionnaires semiannually. Cross-sectional analyses for the current article included 1168 women on ART for whom data on medication adherence were available from their last study visit between April 2013 and March 2014, when the internalized stigma measure was initially introduced. RESULTS The association between internalized stigma and self-reported suboptimal ART adherence was significant for those in racial/ethnic minority groups (AOR = 0.69, P = 0.009, 95% CI: 0.52 to 0.91), but not for non-Hispanic whites (AOR = 2.15, P = 0.19, 95% CI: 0.69 to 6.73). Depressive symptoms, loneliness, and low perceived social support mediated the association between internalized stigma and suboptimal adherence in the whole sample, as well as in the subsample of minority participants. In serial mediation models, internalized stigma predicted less-perceived social support (or higher loneliness), which in turn predicted more depressive symptoms, which in turn predicted suboptimal medication adherence. CONCLUSIONS Findings suggest that interconnected psychosocial mechanisms affect ART adherence, and that improvements in adherence may require multifaceted interventions addressing both mental health and interpersonal factors, especially for minority women.

Abstract
Medication adherence is the "Plus" in the global challenge to have 90% of HIV-infected individuals tested, 90% of those who are HIV positive treated, and 90% of those treated achieve an undetectable viral load. The latter indicates viral suppression, the goal for clinicians treating people living with HIV (PLWH). The comparative importance of different psychosocial scales in predicting the level of antiretroviral adherence, however, has been little studied. Using data from a cross-sectional study of medication adherence with an international convenience sample of 1811 PLWH, we categorized respondent medication adherence as None (0%), Low (1-60%), Moderate (61-94%), and High (95-100%) adherence based on self-report. The survey contained 13 psychosocial scales/indices, all of which were correlated with one another (p < 0.05 or less) and had differing degrees of association with the levels of adherence. Controlling for the influence of race, gender, education, and ability to pay for care, all scales/indices were associated with adherence, with the exception of Berger's perceived stigma scale. Using forward selection stepwise regression, we found that adherence self-efficacy, depression, stressful life events, and perceived stigma were significant predictors of medication adherence. Among the demographic variables entered into the model, nonwhite race was associated with double the odds of being in the None rather than in the High adherence category, suggesting these individuals may require additional support. In addition, asking about self-efficacy, depression, stigma, and stressful life events also will be beneficial in identifying patients requiring greater adherence support. This support is essential to medication adherence, the Plus to 90-90-90.

Abstract
Treatment regimen fatigue (TRF) is a decreased desire and motivation to maintain vigilance in adhering to treatment, and little is known about TRF in people living with HIV. We aimed to develop a conceptual framework of TRF. Five focus groups were conducted in 2014. Eligible participants were (a) HIV infected, (b) at least 18 years of age, (c) prescribed antiretroviral therapy, and (d) fluent in English. Data were analyzed using thematic analysis. Analyses revealed these themes: patient experiences of TRF; etiological factors at the systems, provider, and patient levels; strategies to manage TRF; consequences of TRF; and protective factors that prevent the occurrence of TRF. The results provided a conceptual framework for future investigations to build on in an effort to improve adherence and retention in HIV care. Study results indicate avenues for intervention at multiple levels (systems, provider, and patient) to reduce treatment burden and improve patient resources and capacity.

Abstract
Timely linkage to HIV care (LTC) following an HIV diagnosis is especially important for pregnant women with HIV to prevent perinatal transmission and improve maternal health. However, limited data are available on LTC among U.S. pregnant women. Our analysis aimed to identify HIV diagnoses among childbearing age (CBA) women (15-44 years old) by pregnancy status and to compare LTC of HIV-infected pregnant women to HIV-infected non-pregnant women. We analyzed 2013 CDC-funded HIV testing data from 61 health departments and 151 directly funded community-based organizations among CBA women. LTC includes linkage at any time after an HIV diagnosis and within 90 days after HIV diagnosis. Pearson's chi-square was used to compare LTC of pregnant and non-pregnant women. Data were analyzed using SAS v9.3. Among the 1,379,860 HIV testing events among CBA women in 2013, 0.3% (n = 3690) were HIV-positive. Among all HIV-positive diagnoses with an available pregnancy status (n = 1987), 7%, (n = 138) were pregnant. Among women with pregnancy status data, LTC any time after an HIV-positive diagnosis was 73.2% for pregnant women and 60.7% for non-pregnant women. LTC within 90 days was 71.7% for pregnant women and 56.2% for non-pregnant women. Pregnancy was associated with LTC any time (p < 0.01) and within 90 days of diagnosis (p < 0.01). Compared with non-pregnant women, a higher proportion of pregnant women with HIV were linked to care overall, and linked within 90 days. Pregnancy appears to facilitate better LTC, but improvements are needed for women overall and pregnant women specifically.

Abstract
Among adults living with HIV, unstable housing is a barrier to health. Stably- and unstably-housed adults living with HIV were assessed for over 25 months. At baseline, unstably-housed adults living with HIV had a more recent HIV diagnosis, higher viral loads, worse physical and mental health, lower rates of antiretroviral therapy use and insurance coverage, and higher rates of hard drug use than stably-housed adults living with HIV. At follow-up, the health of both groups was similar, but unstably-housed adults living with HIV reported significantly more hard drug use and mental health symptoms when compared to the stably-housed adults living with HIV. Drug and mental health risks decreased for both groups, but decreases in unprotected sex were greater among unstably-housed adults living with HIV.

Abstract
It has been shown that socioeconomic factors are associated with the prognosis of several chronic diseases; however, there is no recent systematic review of their effect on HIV treatment outcomes. We aimed to review the evidence regarding the existence of an association of socioeconomic status with virological and immunological response to antiretroviral therapy (ART). We systematically searched the current literature using the database PubMed. We identified and summarized original research studies in high-income countries that assessed the association between socioeconomic factors (education, employment, income/financial status, housing, health insurance, and neighbourhood-level socioeconomic factors) and virological response, immunological response, and ART nonadherence among people with HIV-prescribed ART. A total of 48 studies met the inclusion criteria (26 from the United States, six Canadian, 13 European, and one Australian), of which 14, six, and 35 analysed virological, immunological, and ART nonadherence outcomes, respectively. Ten (71%), four (67%), and 23 (66%) of these studies found a significant association between lower socioeconomic status and poorer response, and none found a significant association with improved response. Several studies showed that adjustment for nonadherence attenuated the association between socioeconomic status and ART response. Our review provides strong support that socioeconomic disadvantage is associated with poorer response to ART. However, most studies have been conducted in settings such as the United States without universal free healthcare access. Further study in settings with free access to ART could help assess the impact of socioeconomic status on ART outcomes and the mechanisms by which it operates.

Abstract
Objective: While a growing body of research indicates that implicit cognitive processes play an important role in a range of health behaviors, the assessment of these impulsive, associative mental processes among patients living with HIV has received little attention. This preliminary study explored how multidimensional scaling (MDS) could be used to assess implicit cognitive processes among patients lost to follow-up for HIV care and develop interventions to improve their engagement. Method: The sample consisted of 33 patients who were identified as lost to follow up for HIV care at two urban hospitals. Participants were randomly assigned to either the MDS assessment program or control group. All participants underwent measures designed to gauge behavioral change intentions and treatment motivation. Assessment group participants were interviewed to determine their reactions to the assessment program. Results: The MDS assessment program identified cognitive processes and their relationship to treatment-related behaviors among assessment group participants. Assessment group participants reported significantly greater behavior change intentions than those in the control group (p =.02; Cohen’s d = 0.84). Conclusion: MDS shows promise as a tool to identify implicit cognitive processes related to treatment-related behaviors. Assessments based on MDS could serve as the basis for patient-centered clinical interventions designed to improve treatment adherence and HIV care engagement in general.

Abstract
Best practices in HIV care have the potential to improve patient outcomes and inform practice. We conducted a systematic review of best practices in HIV care that were published from 2003 to 2013. Practices that demonstrated success in achieving desired results based on their objectives were included in the review. Two themes emerged from the eight articles reviewed: (a) the importance of linking newly diagnosed people living with HIV to care and (b) the role of integrated and comprehensive service provision in improving patient outcomes. Inconsistencies in reporting and arbitrary use of the term "best practices" were hurdles in this review.

Abstract
BACKGROUND Incident syphilis among HIV-infected persons indicates the ongoing behavioral risk for HIV transmission. Detectable viral loads (VLs) among coinfected cases may amplify this risk. METHODS Primary and secondary cases reported during 2009-2010 from 4 US sites were crossmatched with local HIV surveillance registries to identify syphilis case-persons infected with HIV before or shortly after the syphilis diagnosis. We examined HIV VL and CD4 results collected within 6 months before or after syphilis diagnosis for the coinfected cases identified. Independent correlates of detectable VLs (≥200 copies/mL) were determined. RESULTS We identified 1675 cases of incident primary or secondary syphilis among persons with HIV. Median age was 37 years; 99.5% were men, 41.1% were African American, 24.5% were Hispanics, and 79.9% of the HIV diagnoses were made at least 1 year before syphilis diagnosis. Among those coinfected, there were no VL results reported for 188 (11.2%); of the 1487 (88.8%) with reported VL results, 809 (54.4%) had a detectable VL (median, 25,101 copies/mL; range, 206-3,590,000 copies/mL). Detectable VLs independently correlated with syphilis diagnosed at younger age, at an sexually transmitted disease clinic, and closer in time to HIV diagnosis. CONCLUSIONS More than half of syphilis case-persons identified with HIV had a detectable VL collected within 6 months of the syphilis diagnosis. This suggests virologic and active behavioral risk for transmitting HIV.

Abstract
BACKGROUND Accumulating evidence suggests responses to HIV that combine individual-level interventions with those that address structural or contextual factors that influence risks and health outcomes of infection. Housing is such a factor. Housing occupies a strategic position as an intermediate structural factor, linking "upstream" economic, social, and cultural determinants to the more immediate physical and social environments in which everyday life is lived. The importance of housing status for HIV prevention and care has been recognized, but much of this attention has focused on homeless individuals as a special risk group. Analyses have less often addressed community housing availability and conditions as factors influencing population health or unstable, inadequate, or unaffordable housing as a situation or temporary state. A focus on individual-level characteristics associated with literal homelessness glosses over social, economic, and policy drivers operating largely outside any specific individual's control that affect housing and residential environments and the health resources or risk exposures such contexts provide. OBJECTIVES We examined the available empirical evidence on the association between housing status (broadly defined), medical care, and health outcomes among people with HIV and analyzed results to inform future research, program development, and policy implementation. SEARCH METHODS We searched 8 electronic health and social science databases from January 1, 1996, through March 31, 2014, using search terms related to housing, dwelling, and living arrangements and HIV and AIDS. We contacted experts for additional literature. SELECTION CRITERIA We selected articles if they were quantitative analyses published in English, French, or Spanish that included at least 1 measure of housing status as an independent variable and at least 1 health status, health care, treatment adherence, or risk behavior outcome among people with HIV in high-income countries. We defined housing status to include consideration of material or social dimensions of housing adequacy, stability, and security of tenure. DATA COLLECTION AND ANALYSIS Two independent reviewers performed data extraction and quality appraisal. We used the Cochrane Risk of Bias Tool for randomized controlled trials and a modified version of the Newcastle Ottawa Quality Appraisal Tool for nonintervention studies. In our quality appraisal, we focused on issues of quality for observational studies: appropriate methods for determining exposure and measuring outcomes and methods to control confounding. RESULTS Searches yielded 5528 references from which we included 152 studies, representing 139,757 HIV-positive participants. Most studies were conducted in the United States and Canada. Studies examined access and utilization of HIV medical care, adherence to antiretroviral medications, HIV clinical outcomes, other health outcomes, emergency department and inpatient utilization, and sex and drug risk behaviors. With rare exceptions, across studies in all domains, worse housing status was independently associated with worse outcomes, controlling for a range of individual patient and care system characteristics. CONCLUSIONS Lack of stable, secure, adequate housing is a significant barrier to consistent and appropriate HIV medical care, access and adherence to antiretroviral medications, sustained viral suppression, and risk of forward transmission. Studies that examined the history of homelessness or problematic housing years before outcome assessment were least likely to find negative outcomes, homelessness being a potentially modifiable contextual factor. Randomized controlled trials and observational studies indicate an independent effect of housing assistance on improved outcomes for formerly homeless or inadequately housed people with HIV. Housing challenges result from complex interactions between individual vulnerabilities and broader economic, political, and legal structural determinants of health. The broad structural processes sustaining social exclusion and inequality seem beyond the immediate reach of HIV interventions, but changing housing and residential environments is both possible and promising.

Abstract
Pre-exposure prophylaxis (PrEP) is a promising HIV prevention approach for men who have sex with men (MSM), however non-adherence could limit its effectiveness. Understanding the experiences of HIV-uninfected MSM taking routine medications can provide valuable insights into open label PrEP adherence in real world settings and guide development of PrEP adherence interventions. In this study, we examined self-reported medication-taking experiences and facilitators and barriers of medication adherence among a geographically-diverse online sample of HIV-uninfected US MSM. Among 1480 participants, 806 (54%) reported taking medications regularly, of whom 80% reported taking medications for treatment and 55% for prevention purposes. Facilitators of medication adherence included establishing a routine, keeping medication visible, and using a pill-box; barriers included forgetting, changes in routine, and being busy or away from home. Only 45% rated their medication-taking ability as excellent, and 36% reported not missing any doses in the past 30 days. In multivariable analyses, older men and those not reporting any adherence barriers were more likely to report excellent adherence, and men willing to use PrEP were more likely to report perfect 30-day adherence. Counseling strategies to build pill-taking routines and support younger MSM are suggested to maximize the public health impact of PrEP.

Abstract
We conducted four rounds of cognitive testing of self-report items that included 66 sociodemographically diverse participants, then field tested the three best items from the cognitive testing in a clinic waiting room (N = 351) and in an online social networking site for men who have sex with men (N = 6,485). As part of the online survey we conducted a randomized assessment of two versions of the adherence questionnaire—one which asked about adherence to a specific antiretroviral medication, and a second which asked about adherence to their “HIV medicines” as a group. Participants were better able to respond using adjectival and adverbial scales than visual analogue or percent items. The internal consistency reliability of the three item adherence scale was 0.89. Mean scores for the two different versions of the online survey were similar (91.0 vs. 90.2, p < 0.05), suggesting that it is not necessary, in general, to ask about individual medications in an antiretroviral therapy regimen when attempting to describe overall adherence.

Abstract
High rates of HIV coinfection among men with syphilis suggest HIV transmission opportunities due to biologic and behavioral risk synergy. We abstracted HIV viral loads for HIV-infected males aged 24 years or younger with a diagnosis of early syphilis (ES) in Maricopa County, Arizona, in order to evaluate HIV infectivity. During 2009 to 2012, there were 56 HIV-infected, ES cases meeting the age criteria, of whom 32 (57%) had a detectable viral load performed within 1 year of syphilis diagnosis (median 21 000 copies/mL, range 130-302 844 copies/mL). Only 4 (7%) of the 56 patients had an undetectable viral load (<100 copies/mL) reported within a year of syphilis diagnosis. Twenty (36%) had no reported viral load or a viral load collected after 1 year of syphilis diagnosis. Among this group of young men coinfected with HIV and ES, many had detectable viral loads collected near the time of syphilis diagnosis, suggesting the potential for HIV transmission.

Abstract
INTRODUCTION The use of single-tablet antiretroviral therapy (ART) regimens and its implications on adherence among HIV-infected women have not been well described. METHODS Participants were enrolled in the Women's Interagency HIV Study, a longitudinal study of HIV infection in US women. We examined semiannual trends in single-tablet regimen use and ART adherence, defined as self-reported 95% adherence in the past 6 months, during 2006-2013. In a nested cohort study, we assessed the comparative effectiveness of a single-tablet versus a multiple-tablet regimen with respect to adherence, virologic suppression, quality of life, and AIDS-defining events, using propensity score matching to account for demographic, behavioral, and clinical confounders. We also examined these outcomes in a subset of women switching from a multiple- to single-tablet regimen using a case-crossover design. RESULTS We included 15,523 person-visits, representing 1727 women (53% black, 29% Hispanic, 25% IDU, median age 47). Use of single-tablet regimens among ART users increased from 7% in 2006% to 27% in 2013; adherence increased from 78% to 85% during the same period (both P < 0.001). Single-tablet regimen use was significantly associated with increased adherence (adjusted risk ratio: 1.05; 95% confidence interval: 1.03 to 1.08) and virologic suppression (risk ratio: 1.06; 95% confidence interval: 1.01 to 1.11), while associations with improved quality of life and fewer AIDS-defining events did not achieve statistical significance. Similar findings were observed among the subset of switchers. CONCLUSIONS Single-tablet regimen use was associated with increased adherence and virologic suppression. Despite this, 15% of women prescribed ART were still not optimally adherent; additional interventions are needed to maximize therapeutic benefits.

Improved virologic outcomes over time for HIV-infected patients on antiretroviral therapy in a cohort from Rio de Janeiro, 1997-2011. BMC Infect Dis 2014; 14:322. [PMID: 24919778 PMCID: PMC4067376 DOI: 10.1186/1471-2334-14-322] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2014] [Accepted: 06/04/2014] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Previous cohort studies have demonstrated the beneficial effects of antiretroviral therapy (ART) on viral load suppression. We aimed to examine the factors associated with virologic suppression for HIV-infected patients on ART receiving care at the Evandro Chagas Clinical Research Institute, Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. METHODS HIV-1 RNA levels and CD4+ T-cell counts at the date closest to midyear (1 July) were evaluated for 1,678 ART-naïve patients ≥ 18 years of age initiating ART between 1997 and 2010. The odds ratios (OR) and 95% confidence intervals (CI) for having an undetectable viral load (≤ 400 copies/mL) were estimated using generalized estimating equations regression models adjusted for clinical and demographic factors. Time-updated covariates included age, years since HIV diagnosis, hepatitis C diagnosis and ART interruptions. RESULTS Between 1997 and 2011, the proportion of patients with an undetectable viral load increased from 6% to 78% and the median [interquartile range] CD4+ T-cell count increased from 207 [162, 343] to 554 [382, 743] cells/μL. Pre-treatment median CD4+ T-cell count significantly increased over the observation period from 114 [37, 161] to 237 [76, 333] cells/μL (p < .001). The per-year adjusted OR (aOR) for having undetectable viral load was 1.18 (95% CI = 1.16-1.21). ART interruptions >1 month per calendar significantly decreased the odds [aOR = 0.32 (95% CI = 0.27-0.38)] of having an undetectable viral load. Patients initiating on a protease inhibitor (PI)-based first-line regimen were less likely to have undetectable viral load [aOR = 0.72 (95% CI = 0.63-0.83)] compared to those initiating on a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen. CONCLUSIONS Our results demonstrate significant improvements in virologic outcomes from 1997 to 2011, which persisted after adjusting for other factors. This may in part be due to improvements in care and new treatment options. NNRTI- versus PI-based first-line regimens were found to be associated with increased odds of having an undetectable viral load, consistent with previous studies. Treatment interruptions were found to be the most important determinant of not having an undetectable viral load. Studies are needed to characterize the reasons for treatment interruptions and to develop subsequent strategies for improving adherence to ART.

Abstract
BACKGROUND Continuous antiretroviral therapy (ART) is important for maintaining viral suppression. This analysis estimates prevalence of and reason for ART discontinuation. METHODS Three-stage sampling was used to obtain a nationally representative, cross-sectional sample of HIV-infected adults receiving HIV care. Face-to-face interviews and medical record abstractions were collected from June 2009 to May 2010. Data were weighted based on known probabilities of selection and adjusted for nonresponse. Patient characteristics of ART discontinuation, defined as not currently taking ART, stratified by provider-initiated versus non-provider-initiated discontinuation, were examined. Weighted logistic regression models predicted factors associated with ART discontinuation. RESULTS Of adults receiving HIV care in the United States who reported ever initiating ART, 5.6% discontinued treatment. Half of those who discontinued treatment reported provider-initiated discontinuation. Provider-initiated ART discontinuation patients were more likely to have a nadir CD4 ≥ 200 cells per cubic millimeter. Non-provider-initiated ART discontinuation patients were more likely to have unmet need for supportive services and to have not received HIV care in the past 3 months. Among all patients who discontinued, younger age, female gender, not having continuous health insurance, incarceration, injection drug use, nadir CD4 count ≥ 2 00 cells per cubic millimeter, unmet need for supportive services, no care in the past 3 months and HIV diagnosis ≥ 5 years before interview were independently associated with ART discontinuation. CONCLUSIONS These findings inform development of interventions to increase ART persistence by identifying groups at increased risk of ART discontinuation. Evidence-based interventions targeting vulnerable populations are needed and are increasingly important as recent HIV treatment guidelines have recommended universal ART.

Abstract
BACKGROUND Alcohol consumption may affect the course of HIV infection and/or antiretroviral therapy (ART). The authors investigated the association between self-reported alcohol consumption and HIV surrogate markers in both treated and untreated individuals. DESIGN Prospective cohort study. METHODS Over a 7-year period, the authors analyzed 2 groups of individuals in the Swiss HIV Cohort Study: (1) ART-naïve individuals remaining off ART and (2) individuals initiating first ART. For individuals initiating first ART, time-dependent Cox proportional hazards models were used to assess the association between alcohol consumption, virological failure, and ART interruption. For both groups, trajectories of log-transformed CD4 cell counts were analyzed using linear mixed models with repeated measures. RESULTS The authors included 2982 individuals initiating first ART and 2085 ART naives. In individuals initiating first ART, 241 (8%) experienced virological failure. Alcohol consumption was not associated with virological failure. ART interruption was noted in 449 (15%) individuals and was more prevalent in severe compared with none/light health risk drinkers [hazard ratio: 2.24, 95% confidence interval: 1.42 to 3.52]. The association remained significant even after adjusting for nonadherence. The authors did not find an association between alcohol consumption and change in CD4 cell count over time in either group. CONCLUSIONS No effect of alcohol consumption on either virological failure or CD4 cell count in both groups of ART-initiating and ART-naive individuals was found. However, severe drinkers were more likely to interrupt ART. Efforts on ART continuation should be especially implemented in individuals reporting high alcohol consumption.

Abstract
This qualitative systematic review examined interventions that promote linkage to or utilization of HIV care among HIV-diagnosed persons in the United States. We conducted automated searches of electronic databases (i.e., MEDLINE, EMBASE, PsycINFO, CINAHL) and manual searches of journals, reference lists, and listservs. Fourteen studies from 19 published reports between 1996 and 2011 met our inclusion criteria. We developed a three-tier approach, based on strength of study design, to evaluate 6 findings on linkage to care and 18 findings on HIV care utilization. Our review identified similar strategies for the two outcomes, including active coordinator's role in helping with linking to or utilizing HIV care; offering information and education about HIV care; providing motivational or strengths-based counseling; accompanying clients to medical appointments and helping with appointment coordination. The interventions focused almost exclusively on individual-level factors. More research is recommended to examine interventions that address system and structural barriers.

Abstract
Effective antiretroviral therapy has led to substantial improvements in health-related outcomes among individuals with HIV. Despite advances in HIV pharmacotherapy, suboptimal medication adherence remains a significant barrier to successful treatment. Although several factors have been associated with medication adherence in the extant literature, study assessing the effects of some of the neurobehavioral features specific to HIV has been limited. Moreover, although there is a growing body of literature measuring medication adherence in HIV prospectively, few employ advanced statistical methodologies suited to handle advanced models with multiple predictors that would strengthen our understanding of medication adherence trajectories in HIV. This study sought to integrate traditionally assessed predictors of medication adherence with neurobehavioral features of HIV in a longitudinal study of medication adherence to combined antiretroviral therapy (cART). The current study used multilevel modeling to examine a wide arrangement of categories of factors - demographic, medication related, psychosocial, and neurobehavioral - on medication adherence. The sample consisted of 235 HIV+ individuals whose medication adherence was monitored over the course of six months using electronic monitoring devices. After controlling for the effects of demographic, medication, and psychosocial factors, neurobehavioral features added predictive validity to the model. In the final model, simultaneously controlling for the effects of each of the predictors within all the categories, age, self-efficacy, executive functioning, apathy, and frequency of stimulant use emerged as unique individual predictors of average medication adherence across the 6-month study. Self-efficacy and irritability predicted changes in medication adherence over time. Adherence behavior is multidetermined. Adequate assessment of these factors, combined with timely intervention, appears to be warranted in order to boost adherence rates.
