Abstract
The burden of depression and HIV is high among people who inject drugs (PWID), yet the effect of depression on transmission risk behaviors is not well understood in this population. Using causal inference methods, we analyzed data from 455 PWID living with HIV in Vietnam 2009-2013. Study visits every 6 months over 2 years measured depressive symptoms in the past week and injecting and sexual behaviors in the prior 3 months. Severe depressive symptoms (vs. mild/no symptoms) increased injection equipment sharing (risk difference [RD] = 3.9 percentage points, 95% CI -1.7, 9.6) but not condomless sex (RD = -1.8, 95% CI -6.4, 2.8) as reported 6 months later. The cross-sectional association with injection equipment sharing at the same visit (RD = 6.2, 95% CI 1.4, 11.0) was stronger than the longitudinal effect. Interventions on depression among PWID may decrease sharing of injection equipment and the corresponding risk of HIV transmission.Clinical trial registration ClinicalTrials.gov NCT01689545.

Abstract
BACKGROUND There are more than two million people living with HIV (PLH) in India, with more than 30% on antiretroviral treatment (ART) estimated to be non-adherent. This study aimed to (I) document adherence rates and related factors among ART patients in a large ART clinic in India, and (II) pilot test daily and weekly interactive voice response (IVR) calls to improve ART adherence and related outcomes. METHODS ART patients reporting missing at least one dose in prior 6 months (N=362) were enrolled and assessed via self-report and medical record review. Participants were randomized to one of two conditions: (I) twice-daily IVR call reminders with self-management support messaging, plus a weekly IVR adherence assessment; or (II) an attention control, with only weekly IVR adherence assessment. Participants completed study assessments at baseline, 2-, 4-, and 6-months with high retention (88% to 96%). RESULTS Intention-to-treat analyses found limited support for intervention effects for improving or maintaining ART adherence or CD4 counts between the two study arms over 6-months follow-up. Adherence increased significantly in the six months prior to baseline from about 65% to >95% with perfect adherence based on pill counts from medical records and consistent with patient self-report measures, which presented ceiling effects for detecting improvements in ART adherence in response to IVR intervention exposure. There was also limited support for intervention effects on secondary, self-management outcomes. CONCLUSIONS High levels of adherence were sustained throughout the 6-month RCT. IVR regulation changes in India delayed study launch for 6 months, which likely allowed mobilization of improved adherence at the clinic, provider and patient levels in anticipation of the study launch. Therefore, ceiling effects limited inferences on intervention effects to improve adherence. Results suggest that clinic-level adherence monitoring may be sufficient to mobilize adherence improvements by providers and patients. TRIAL REGISTRATION ClinicalTrials.gov registration #NCT02118454.

Abstract
PURPOSE OF REVIEW People living with human immunodeficiency virus/AIDS (PLWHA) experience high prevalence of substance use disorders (SUD). HIV care settings represent a unique opportunity to identify possible SUD, to provide SUD interventions, and to improve linkage to SUD treatment. The aims of this paper are to (a) review and critique the extant literature examining substance use screening approaches among PLWHA in HIV care settings and (b) provide recommendations for future clinical practice. RECENT FINDINGS Twenty-one peer-reviewed articles that examined substance screening approaches employed in HIV and other primary care settings were included in the review. There was limited literature reporting on the implementation and evaluation of substance use screening practices within HIV care settings, and methodological rigor varied across studies. Further, the use of validated substance use screening measures or incorporation of other substance use screening approaches (e.g., use of urine drug testing) within routine HIV care practice is limited. Strategies to implement routine substance use screening within HIV care and incorporate additional substance use assessment, brief interventions, and referral to specialty substance use treatment are discussed. Use of self-report substance use screening measures using web- or computer-delivered approaches that can be integrated within electronic health record systems is particularly promising. HIV care practices should consider potential models to optimally screen and treat SUD. Co-location of HIV and SUD treatment services may be optimal; when co-located services are not possible, strategies to consistently provide brief intervention approaches and referrals to specialty SUD treatment are needed.

Abstract
BACKGROUND HIV-positive persons who use stimulants such as methamphetamine experience difficulties navigating the HIV care continuum that undermine the benefits of antiretroviral therapy (ART). However, few studies have examined the association of stimulant use with viral suppression in the era of universal ART. SETTING Zuckerberg San Francisco General Hospital. METHODS HIV-positive persons participating in a clinical cohort study and taking ART completed assessments every 4-6 months. The exposure was the cumulative, time-varying proportion of assessments with any self-reported stimulant use. The time-varying outcome, HIV viral suppression (ie, <200 copies/mL), was measured at assessments or extracted from the clinical record. RESULTS In total, 1635 HIV-positive participants on ART contributed 17,610 person-visits over a median of 2.3 [interquartile range (IQR) = 1.0-5.3] years of follow-up. Participants were middle-aged (median = 45.0; IQR = 38.0-52.0), predominantly white (57%), sexual minority men (78%), with a median CD4 T-cell count of 409 (IQR = 225-640) cells/mm at enrollment. Significant increases in odds of viral suppression over time were less pronounced among stimulant users compared with nonusers, particularly before the advent of universal ART. Increasing odds of viral suppression were paralleled by declining stimulant use over time. In the universal ART era, increasing odds of viral suppression were observed at lower levels of stimulant use, but not when participants reported using stimulants at every visit. CONCLUSIONS Although ART benefits are still not achieved as rapidly in stimulant users, this disparity is not as large in the era of universal ART.

Abstract
HIV is transmitted in social and sexual relationships, and HIV transmission risks, as well as protective actions, are evolving as HIV epidemics unfold. The current focus of HIV prevention is centered on antiretroviral medications used to reduce HIV infectiousness in persons already infected with HIV [treatment as prevention (TasP)]. The same medications used to treat infected persons can also be used by uninfected persons as pre-exposure prophylaxis (PrEP) to reduce the infectivity of HIV. Both PrEP and TasP are effective when adherence is high and individuals do not have co-occurring sexually transmitted infections. HIV prevention is most effective and efficient when delivered within sexual networks with high HIV prevalence. Specific network characteristics are recognized as important facilitators of HIV transmission; these characteristics include the degree of similarity among network members (homophily), gender role norms, and belief systems. Since 2011, HIV risk has been redefined based on infectiousness and infectivity, ushering in a new era of HIV prevention with the potential to end HIV epidemics.

Abstract
OBJECTIVES We conducted a randomized clinical trial to test a mobile health behavioral intervention designed to enhance HIV treatment as prevention (B-TasP) by simultaneously increasing combination antiretroviral therapies (cART) adherence and improving the sexual health of people living with HIV. METHODS A cohort of sexually active men (n = 383) and women (n = 117) living with HIV were enrolled. Participants were baseline assessed and randomized to either (1) B-TasP adherence and sexual health intervention or (2) general health control intervention. Outcome measures included HIV RNA viral load, cART adherence monitored by unannounced pill counts, indicators of genital tract inflammation, and sexual behaviors assessed over 12 months. RESULTS Eighty-six percent of the cohort was retained for 12-month follow-up. The B-TasP intervention demonstrated significantly lower HIV RNA, OR = 0.56, P = 0.01, greater cART adherence, Wald χ = 33.9, P = 0.01, and fewer indicators of genital tract inflammation, Wald χ = 9.36, P = 0.05, over the follow-up period. Changes in sexual behavior varied, with the B-TasP intervention showing lower rates of substance use in sexual contexts, but higher rates of condomless sex with non-HIV positive partners occurred in the context of significantly greater beliefs that cART reduces HIV transmission. CONCLUSIONS Theory-based mobile health behavioral interventions can simultaneously improve cART adherence and sexual health in people living with HIV. Programs aimed to eliminate HIV transmission by reducing HIV infectiousness should be bundled with behavioral interventions to maximize their impact and increase their chances of success.

Abstract
Family Coaching is proposed as a new delivery format for evidence-based prevention programs (EBPPs). Three recent developments in health promotion support the potential efficacy of Family Coaching: (1) renewed interest in integrated prevention programs for multiple risk factors and behavior changes, (2) broad and long-term impacts of family-based interventions, and (3) popular acceptance of "coaching" as a nonstigmatizing, goal-focused intervention strategy. Family coaches are community members and paraprofessionals trained in common elements of EBPP. Family Coaching has specific goals, is short term, and has definable outcomes. Coaches frame the program's goals to be consistent with the family's values, normalize the family's experience, assess their strengths, and help the family set goals and develop skills and routines to problem solve challenging situations. Broad dissemination of EBPP will be facilitated with delivery formats that are flexible to meet families' priorities and providers' desires and capacities to tailor programs to local contexts.

Abstract
Community-wide awareness that antiretroviral therapies (ART) provides protection against HIV has the potential to increase perceived safety and thereby increase condomless anal sex among men who have sex with men (MSM). Furthermore, reductions in condom use can increase exposure to sexually transmitted infections, which in turn can reduce the protective effects of ART on HIV transmission. The current study extends previous community-based behavioral surveillance research on beliefs regarding use of ART for HIV prevention and sexual practices among MSM. Anonymous cross-sectional community surveys were collected from 1831 men at the same gay pride event in Atlanta, GA four times over nearly two decades; 1997, 2005-2006 (the 2006 survey over-sampled African-Americans to diversify the study), and 2015. Results indicate clear and consistent trends of increasing beliefs that HIV treatments reduce HIV transmission risks, reflecting the dissemination of HIV prevention research findings. Changes in treatment beliefs coincide with increased rates of condomless anal intercourse. Increased beliefs that treatments prevent HIV and increased condomless anal sex were observed for both HIV positive men and men who had not tested HIV positive. Results illustrate the emergence of an era where ART is the focus of HIV prevention and community-held beliefs and behaviors regarding definitions of risk create a new and potentially problematic environment for HIV transmission.

Abstract
Antiretroviral therapy (ART) improves the health of people living with HIV and can reduce infectiousness, preventing HIV transmission. The potential preventive benefits of ART are undermined by beliefs that it is safe to have condomless sex when viral load is below levels of detection (infectiousness beliefs and risk perceptions). In this study, we hypothesized that infectiousness beliefs and HIV transmission risk perceptions would prospectively predict people living with HIV engaging in more condomless sex with HIV-negative and unknown HIV status sex partners. Sexually active HIV-positive men (n = 538, 76 %) and women (n = 166, 24 %) completed computerized interviews of sexually transmitted infection (STI) symptoms and diagnoses, unannounced pill counts for medication adherence, medical chart-abstracted HIV viral load, and 28 daily cell-phone-delivered prospective sexual behavior assessments. Results showed that a total of 313 (44 %) participants had engaged in condomless sex with HIV-negative/unknown status sex partners, and these individuals demonstrated higher rates of STI symptoms and diagnoses. Two-thirds of participants who had condomless sex with HIV-negative/unknown status partners had not disclosed their HIV status. Multivariable logistic regression models showed that beliefs regarding viral load and HIV infectiousness and perceptions of lower risk of HIV transmission resulting from HIV viral suppression predicted condomless sex with potentially uninfected partners over and above sex behaviors with HIV-positive partners and STI symptoms/diagnoses. Interventions that address HIV status disclosure and aggressively treat STI in sexually active people living with HIV should routinely accompany the use of HIV treatments as prevention.

Abstract
BACKGROUND Hepatitis B virus (HBV) has a detrimental effect on human immunodeficiency virus (HIV) natural course, and HBV vaccination is less effective in the HIV infected. We examine the protective effect of dually active antiretroviral therapy (DAART) for HIV/HBV (tenofovir, lamivudine, and emtricitabine) in a large cohort encompassing heterosexuals, men who have sex with men, and intravenous drug users who are HIV infected yet susceptible to HBV, with comprehensive follow-up data about risky behavior and immunological profiles. METHODS We defined an incident HBV infection as the presence of any of HBV serological markers (hepatitis B surface antigen, anti-hepatitis B core antibodies, or HBV DNA) after a negative baseline test result for anti-hepatitis B core antibodies. Patients with positive anti-hepatitis B surface antigen serology were excluded. Cox proportional hazards models were used, with an incident case of HBV infection as the outcome variable. RESULTS We analyzed 1716 eligible patients from the Swiss HIV Cohort Study with 177 incident HBV cases. DAART was negatively associated with incident HBV infection (hazard ratio [HR], 0.4; 95% confidence interval [CI], .2-.6). This protective association was robust to adjustment (HR, 0.3; 95% CI, .2-.5) for condomless sex, square-root-transformed CD4 cell count, drug use, and patient demographics. Condomless sex (HR, 1.9; 95% CI, 1.4-2.6), being a man who has sex with men (2.7; 1.7-4.2), and being an intravenous drug user (3.8; 2.4-6.1) were all associated with a higher hazard of contracting HBV. CONCLUSIONS Our study suggests that DAART, independently of CD4 cell count and risky behavior, has a potentially strong public health impact, including pre-exposure prophylaxis of HBV coinfection in the HIV infected.

Abstract
The purpose of this study was to identify key psychosocial characteristics of HIV-infected women who exhibit different levels of both ART adherence and risk behaviors. We analyzed baseline data from 193 predominately African American HIV-infected women participating in a behavioral clinical trial. Women were categorized into high/low groups based on levels of adherence and risky behaviors. There was a significant interaction effect for internal motivation for adherence. Women at high risk for poor health and transmitting HIV (low adherence/high risk group) had the lowest levels of internal motivation and also reported more difficult life circumstances. Gender roles, caretaking and reliance on men for economic and other support may promote external versus internal motivation as well as riskier behaviors in this group. The highest levels of internal motivation were found in those with High Adherence/High Risk behaviors. This group was highly knowledgeable about HIV and had the lowest VL. Compared to others, this group seems to tolerate risky behaviors given their high level of adherence. Adherence and risk reduction behaviors are key to individual and public health. Motivation and risk compensation should be addressed when providing interventions to women living with HIV.

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
Social and psychological barriers to the disclosure of one's seropositive HIV status to significant others and poor adherence to taking medications pose significant challenges to the scaling-up of access to antiretroviral treatment (ART) in the workplace. Such barriers are predictive of sub-optimal treatment outcomes and bedevil HIV-prevention interventions at a societal level. Against this background, this article explores the lived experiences of 19 HIV-positive male participants, between the ages of 33 and 57 years, who were enrolled in an ART programme managed at an occupational health clinic at a mining company in South Africa. The majority of these mineworkers had been aware of their HIV status for between 5 and 7 years. The study explored psychological and relational factors, as aspects of these participants lived experiences, which had a bearing on their adherence to their ART regimen and the disclosure choices that they made regarding their HIV status. In our sample, those participants who were adherent demonstrated higher levels of control and acceptance of their HIV infection and were more confident in their ability to manage their treatment, while the group who were non-adherent presented with lower levels of adherence motivation and self-efficacy, difficulties in maintaining a healthy lifestyle and significant challenges in maintaining control over their lives. While most of the men favoured disclosing their HIV status to their partners for the sake of treatment support, they were less sure about disclosing to family members and non-family members, respectively, because of their need to protect these persons and due to their fear of being stigmatised. It was evident that treatment adherence choices and behaviours were impacted by psychological and relational factors, including disclosure decisions. We conclude with a bivariate model for understanding the adherence behaviours that influenced different patterns of ART adherence among the sample, and offer recommendations for HIV-prevention and treatment interventions in a mining workplace.

Abstract
Introduction Antiretroviral therapy (ART) improves the health of people living with HIV and has the potential to reduce HIV infectiousness, thereby preventing HIV transmission. However, the success of ART for HIV prevention hinges on sustained ART adherence and avoiding sexually transmitted infections (STI). Objectives To determine the sexual behaviours and HIV transmission risks of individuals with suppressed and unsuppressed HIV replication (i.e., viral load). Methods Assessed HIV sexual transmission risks among individuals with clinically determined suppressed and unsuppressed HIV. Participants were 760 men and 280 women living with HIV in Atlanta, GA, USA, who completed behavioural assessments, 28-daily prospective sexual behaviour diaries, one-month prospective unannounced pill counts for ART adherence, urine screening for illicit drug use and medical record chart abstraction for HIV viral load. Results Individuals with unsuppressed HIV demonstrated a constellation of behavioural risks for transmitting HIV to uninfected sex partners that included symptoms of STI and substance use. In addition, 15% of participants with suppressed HIV had recent STI symptoms/diagnoses, indicating significant risks for sexual infectiousness despite their HIV suppression in blood plasma. Overall, 38% of participants were at risk for elevated sexual infectiousness and just as many engaged in unprotected sexual intercourse with non-HIV-infected partners. Conclusions Implementation strategies for using HIV treatments as HIV prevention requires enhanced behavioural interventions that extend beyond ART to address substance use and sexual health that will otherwise undermine the potential preventive impact of early ART.

Abstract
BACKGROUND The criminal justice system (CJS), specifically prisons and jails, is ideally suited for uniform screening of psychiatric (PD) and substance use disorders (SUDs) among people living with HIV/AIDS (PLWHA), who are concentrated in these settings. By accurately diagnosing PDs and SUDs in these controlled settings, treatment can be initiated and contribute to improved continuity of care upon release. In the context of PLWHA, it may also improve combination antiretroviral treatment (cART) adherence, and reduce HIV transmission risk behaviors. METHODS A retrospective data analysis was conducted by creating a cohort of PLWHA transitioning to the community from prison or jail enrolled who were enrolled in a controlled trial of directly administered antiretroviral (DAART). Participants were systematically assessed for PDs and SUDs using the Mini International Neuropsychiatric Interview (MINI), a standardized psychiatric assessment tool, and compared to diagnoses documented within the correctional medical record. RESULTS Findings confirm a high prevalence of Axis I PDs (47.4%) and SUDs (67.1%) in PLWHA even after prolonged abstinence from alcohol and drugs. Although prevalence of PDs and SUDs were high in the medical record, there was fair to poor agreement among PDs using the MINI, making evident the potential benefit of more objective and concurrent PD assessments to guide treatment. CONCLUSIONS Additional PD diagnoses may be detected in PLWHA in CJS using supplementary and objective screening tools. By identifying and treating PDs and SUDs in the CJS, care may be improved and may ultimately contribute to healthier outcomes after community release if patients are effectively transitioned.

Abstract
As individuals with HIV infection are living longer, the management of psychiatric disorders has increasingly been incorporated into comprehensive care. Individuals were recruited from an outpatient HIV clinic to assess the prevalence and related associations of current psychiatric disorders and biomarkers. Of the 201 participants who completed the interviews, the median age was 43.5 years, and the majority was male and African American. Most were receiving HIV therapy and 78% of those had achieved virologic suppression. Prevalent psychiatric diagnoses included major depressive disorder, generalized anxiety, and agoraphobia. Alcohol and cocaine/crack abuse and dependence were common substance use disorders. Current receipt of HIV therapy was less common among those diagnosed with generalized anxiety disorder. Agoraphobia was the only disorder associated with unsuppressed viral load. Psychiatric and substance use disorders are highly prevalent among an urban HIV clinic population, although we identified few associations between psychiatric diagnoses and HIV diseases status.

Abstract
Background The reduction of HIV transmission risk behaviors among those infected with HIV remains a major global health priority. Psychosocial characteristics have proven to be important correlates of sexual transmission risk behaviors in high-income countries, but little attention has focused on the influence of psychosocial and psychological factors on sexual transmission risk behaviors in African cohorts. Methodology and Principal Findings The CHAT Study enrolled a representative sample of 499 HIV-infected patients in established HIV care and 267 newly diagnosed HIV-infected individuals from the Kilimanjaro Region of Tanzania. Participants completed in-person interviews every 6 months for 3 years. Using logistic random effects models to account for repeated observations, we assessed sociodemographic, physical health, and psychosocial predictors of self-reported unprotected sexual intercourse. Among established patients, the proportion reporting any recent unprotected sex was stable, ranging between 6–13% over 3 years. Among newly diagnosed patients, the proportion reporting any unprotected sex dropped from 43% at baseline to 11–21% at 6–36 months. In multivariable models, higher odds of reported unprotected sex was associated with female gender, younger age, being married, better physical health, and greater post-traumatic stress symptoms. In addition, within-individual changes in post-traumatic stress over time coincided with increases in unprotected sex. Conclusions and Significance Changes in post-traumatic stress symptomatology were associated with changes in sexual transmission risk behaviors in this sample of HIV-infected adults in Tanzania, suggesting the importance of investing in appropriate mental health screening and intervention services for HIV-infected patients, both to improve mental health and to support secondary prevention efforts.

Abstract
Depressed mood has been associated with HIV transmission risk behavior. To determine whether effective depression treatment could reduce the frequency of sexual risk behavior, we analyzed secondary outcome data from a 36-week, two-arm, parallel-design, randomized controlled trial, in which homeless and marginally housed, HIV-infected persons with comorbid depressive disorders were randomized to receive either: (a) directly observed treatment with the antidepressant medication fluoxetine, or (b) referral to a local public mental health clinic. Self-reported sexual risk outcomes, which were measured at 3, 6, and 9 months, included: total number of sexual partners, unprotected sexual intercourse, unprotected sexual intercourse with an HIV-uninfected partner or a partner of unknown serostatus, and transactional sex. Estimates from generalized estimating equations regression models did not suggest consistent reductions in sexual risk behaviors resulting from treatment. Mental health interventions may need to combine depression treatment with specific skills training in order to achieve durable impacts on HIV prevention outcomes.

Abstract
This study evaluated dual process interaction models of HIV-risk behavior among drug offenders. A dual process approach suggests that decisions to engage in appetitive behaviors result from a dynamic interplay between a relatively automatic associative system and an executive control system. One synergistic type of interplay suggests that executive functions may dampen or block effects of spontaneously activated associations. Consistent with this model, latent variable interaction analyses revealed that drug offenders scoring higher in affective decision making were relatively protected from predictive effects of spontaneous sex associations promoting risky sex. Among drug offenders with lower levels of affective decision making ability, spontaneous sexually-related associations more strongly predicted risky sex (lack of condom use and greater number of sex partners). These findings help elucidate associative and control process effects on appetitive behaviors and are important for explaining why some individuals engage in risky sex, while others are relatively protected.

Abstract
Medications used in the treatment of human immunodeficiency virus (HIV) often have drug-drug interactions which complicate treatment of psychiatric illnesses in HIV-infected patients. Protease inhibitors (PIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) are the two classes of HIV medications most likely to be involved with interactions, with the majority occurring via the cytochrome P450 (CYP450) system. These interactions can result in either increased or decreased exposure to psychotropic and antiretroviral medications, often requiring dosage adjustments and increased monitoring. This article reviews some of the major drug interactions with antiretroviral agents.

Abstract
BACKGROUND The extent to which patients follow treatments as prescribed is pivotal to treatment success. An exceptionally high level (> 95%) of HIV medication adherence is required to suppress viral replication and protect the immune system and a similarly high level (> 80%) of adherence has also been suggested in order to benefit from prescribed exercise programmes. However, in clinical practice, adherence to both often falls below the desirable level. This project aims to investigate a wide range of psychological and personality factors that may lead to adherence/non-adherence to medical treatment and exercise programmes. METHODS HIV positive patients who are referred to the physiotherapist-led 10-week exercise programme as part of the standard care are continuously recruited. Data on social cognitive variables (attitude, intention, subjective norms, self-efficacy, and outcome beliefs) about the goal and specific behaviours, selected personality factors, perceived quality of life, physical activity, self-reported adherence and physical assessment are collected at baseline, at the end of the exercise programme and again 3 months later. The project incorporates objective measures of both exercise (attendance log and improvement in physical measures such as improved fitness level, weight loss, improved circumferential anthropometric measures) and medication adherence (verified by non-invasive hair analysis). DISCUSSION The novelty of this project comes from two key aspects, complemented with objective information on exercise and medication adherence. The project assesses beliefs about both the underlying goal such as following prescribed treatment; and about the specific behaviours such as undertaking the exercise or taking the medication, using both implicit and explicit assessments of patients' beliefs and attitudes. We predict that i) the way people think about the underlying goal of their treatments explains medication and exercise behaviours over and above the effects of the behaviour-specific thinking and ii) the relationship between adherence to exercise and to medical treatment is stronger among those with more favourable views about the goal. Results from this study should identify the key contributing factors to inform subsequent adherence research and afford a more streamlined assessment matrix. The project also aims to inform patient care practices. UK CLINICAL RESEARCH NETWORK REGISTRATION NUMBER: UKCRN 7842.

Abstract
Assessing medication adherence in already difficult-to-treat HIV-infected subpopulations presents a unique challenge. The objective of this study was to compare different approaches to assessing medication adherence: (1) electronic medication monitoring, (2) standardized self-report questionnaire, and (3) self-report visual analogue scale, and to determine whether antiretroviral therapy (ART) adherence measures differed for HIV-infected persons with bipolar disorder (HIV+ /BD+) as compared to HIV-infected persons without bipolar disorder (HIV+ /BD-). ART adherence was assessed for 74 HIV-positive participants using the Medication Event Monitoring System (MEMS), AIDS Clinical Trials Group (ACTG) adherence questionnaire, and visual analogue scale (VAS). Participants were classified as adherent or nonadherent on each measure by previously validated cutscores. Correlations and logistic regressions were used to examine associations between adherence measures and demographic and clinical variables. In the HIV+ /BD- group, significant correlations existed between each self-report measure and the MEMS. Males comprised 81% of the study population. Participants averaged 44 years of age and 13 years of education. No significant correlations were found among adherence measures in the HIV+ /BD+ group. Among participants reporting adherence on either self-report measure but classified as nonadherent based on MEMS, 94% had a diagnosis of bipolar disorder. Bipolar disorder was a significant predictor of adherence classification discordance among self-report measures. Our findings suggest that it remains difficult to assess ART adherence among HIV-positive individuals with bipolar disorder. Combined approaches of self-report and objective measures may be the best way to estimate adherence, and may provide the best basis for interventions designed to improve adherence in difficult-to-treat populations.

Abstract
BACKGROUND Prior research established that psychological factors are associated with the frequency of stimulant (i.e., cocaine, crack, and methamphetamine) use among substance-using men who have sex with men (MSM). The present investigation examined whether and how psychological factors are associated with engagement in any stimulant use in the broader population of MSM. METHODS A probability sample of 879 MSM residing in San Francisco was obtained using random digit dialing from May of 2002 through January of 2003. Of these, 711 participants (81%) completed a mail-in questionnaire that assessed psychological factors and substance use. After accounting for demographic factors, a multiple logistic regression analysis examined correlates of any self-reported stimulant use during the past 6 months. Path analyses examined if the use of alcohol or other substances to avoid negative mood states (i.e., substance use coping) mediated the associations of sexual compulsivity and depressed mood with stimulant use. RESULTS Younger age (adjusted OR [AOR]=0.58; 95% CI=0.47-0.70), HIV-positive serostatus (AOR=2.55; 95% CI=1.61-4.04), greater depressed mood (AOR=1.26; 95% CI=1.05-1.52) and higher sexual compulsivity (AOR=1.46; 95% CI=1.18-1.80) were independently associated with increased odds of stimulant use. Substance use coping partially mediated the associations of sexual compulsivity (β(indirect)=0.11, p<.001) and depressed mood (β(indirect)=0.13, p<.001) with stimulant use. CONCLUSIONS Clinical research is needed to examine if interventions targeting sexual compulsivity and emotion regulation reduce stimulant use among MSM.

Abstract
BACKGROUND Using antiretroviral therapies for HIV prevention relies on patient adherence and avoidance of co-occurring sexually transmitted infections. PURPOSE The objective of this study is to simultaneously examine HIV treatment adherence and sexual risks for HIV transmission. METHODS This study is a prospective cohort of 201 men and 55 women diagnosed with HIV/AIDS infection. RESULTS A total of 32% men and 39% women engaged in unprotected intercourse with at least one HIV negative or unknown HIV status sex partner over 12 months. Nearly half (46%) of participants with HIV negative or unknown HIV status unprotected sex partners had detectable HIV viral load and were significantly more likely to have contracted a sexually transmitted infection since their HIV diagnosis. Individuals at higher risk for transmitting HIV were also less adherent to antiretroviral therapies. CONCLUSIONS Programs that aim to use antiretroviral therapies for HIV prevention require careful attention to adherence, sexually transmitted co-infections, and substance use.

Abstract
BACKGROUND Antiretroviral therapies (ARTs) offer promising new avenues for HIV prevention. Unfortunately, people infected with HIV who have co-occurring sexually transmitted infections (STIs) are more infectious than suggested by the amount of virus in their peripheral blood. We examined the history of sexually transmitted coinfections in people living with HIV. METHODS People living with HIV/AIDS completed confidential computerized interviews that assessed history of STI, sexual behaviors, and STI knowledge. RESULTS Among 414 men and 156 women currently receiving ART, 53% had been diagnosed with at least 1 STI since testing HIV positive; 24% women, 19% men, and 11% transgender persons had been diagnosed with an STI in the past year. History of STI was associated with younger age, greater STI knowledge, substance use, and ART nonadherence. CONCLUSIONS Aggressive strategies for detecting and treating STI in people receiving ART will be necessary to achieve protective benefits.

Abstract
There have been dramatic increases in access to antiretroviral therapy (ART) across the developing world, and growing public health attention has focused on the possibility of utilizing ART as a means of slowing the global HIV epidemic. The preventive impact of ART will likely depend on decreasing levels of sexual risk behaviors following treatment initiation. The current review study examines the impact of wider access to ART on sexual risk behaviors among HIV-infected individuals in the developing world. The observational studies to date demonstrate that ART is associated with a significant reduction in unprotected sex following treatment initiation. Although data on the impact of ART on possible risk compensation are rapidly expanding across the developing world, more evidence is still needed before we can safely conclude expanded treatment will result in durable decreases in sexual risk behaviors.

Abstract
Family-based interventions are efficacious for human immunodeficiency virus (HIV) detection, prevention, and care, but they are not broadly diffused. Understanding intervention adaptation and translation processes can support evidence-based intervention (EBI) diffusion processes. This paper provides a narrative review of a series of EBI for families affected by HIV (FAH) that were adapted across five randomized controlled trials in the US, Thailand, and South Africa over 15 years. The FAH interventions targeted parents living with HIV and their children or caregiver supports. Parents with HIV were primarily mothers infected through sexual transmission. The EBIs for FAH are reviewed with attention to commonalities and variations in risk environments and intervention features. Frameworks for common and robust intervention functions, principles, practice elements, and delivery processes are utilized to highlight commonalities and adaptations for each location, time period, and intervention delivery settings. Health care, housing, food, and financial security vary dramatically in each risk environment. Yet, all FAH face common health, mental health, transmission, and relationship challenges. The EBIs efficaciously addressed these common challenges and were adapted across contexts with fidelity to robust intervention principles, processes, factors, and practices. Intervention adaptation teams have a series of structural decision points: mainstreaming HIV with other local health priorities or not; selecting an optimal delivery site (clinics, homes, community centers); and how to translate intervention protocols to local contexts and cultures. Replication of interventions with fidelity must occur at the level of standardized functions and robust principles, processes, and practices, not manualized protocols. Adopting a continuous quality improvement paradigm will enhance rapid and global diffusion of EBI for FAH.

Abstract
Russia has seen one of the world's fastest-growing HIV epidemics. Transmission risk behavior, HAART-taking, and psychosocial distress of the growing population of Russian people living with HIV (PLH) in the HAART era are understudied. Participants of a systematically-recruited cross-sectional sample of 492 PLH in St. Petersburg completed measures of sexual and drug injection practices, adherence, perceived discrimination, and psychosocial distress. Since learning of their status, 58% of participants had partners of HIV-negative or unknown serostatus (mean = 5.8). About 52% reported unprotected intercourse with such partners, with 30% of acts unprotected. Greater perceived discrimination predicted lower condom use. A 47% of IDU PLH still shared needles, predicted by having no primary partner, lower education, and more frequently-encountered discrimination. Twenty-five percentage of PLH had been refused general health care, 11% refused employment, 7% fired, and 6% forced from family homes. Thirty-nine percentage of participants had probable clinical depression, 37% had anxiety levels comparable to psychiatric inpatients, and social support was low. Of the 54% of PLH who were offered HAART, 16% refused HAART regimens, and 5% of those on the therapy took less than 90% of their doses. Comprehensive community services for Russian PLH are needed to reduce AIDS-related psychosocial distress and continued HIV transmission risk behaviors. Social programs should reduce stigma and discrimination, and promote social integration of affected persons and their families.

Abstract
OBJECTIVES We conducted a randomized clinical trial to test an integrated behavioral intervention designed to enhance using HIV treatment as prevention by improving medication adherence, reducing risks for other sexually transmitted infections, and minimizing risk compensation beliefs. METHODS Individuals living with HIV/AIDS (n = 436) participated in a randomized clinical trial testing an intensive behavioral intervention aimed at reducing HIV transmission risks compared with an attention control condition. We used unannounced pill counts to monitor antiretroviral therapy adherence and computerized interviews to measure risk behaviors. RESULTS The integrated transmission risk reduction intervention demonstrated increased antiretroviral therapy adherence and less unprotected intercourse with nonseroconcordant partners at 3- and 6-month follow-ups as well as fewer new sexually transmitted infections diagnosed over the 9-month follow-up period (adjusted odds ratio = 3.0; P < .05; 95% confidence interval = 1.01, 9.04). The integrated intervention also reduced behavioral risk compensation beliefs. CONCLUSIONS A theory-based integrated behavioral intervention can improve HIV treatment adherence and reduce HIV transmission risks. HIV treatment as prevention should be bundled with behavioral interventions to maximize effectiveness.

Abstract
In light of the increasing availability of generic highly active antiretroviral therapy (HAART) in India, further data are needed to examine variables associated with HAART nonadherence among HIV-infected Indians in clinical care. We conducted a cross-sectional analysis of 198 HIV-infected South Indian men and women between January and April 2008 receiving first-line non-nucleoside reverse transcriptase inhibitor (NNRTI)-based HAART. Nonadherence was defined as taking less than 95% of HAART doses in the last 1 month, and was examined using multivariable logistic regression models. Half of the participants reported less than 95% adherence to HAART, and 50% had been on HAART for more than 24 months. The median CD4 cell count was 435 cells per microliter. An increased odds of nonadherence was found for participants with current CD4 cell counts greater than 500 cells per microliter (adjusted odds ratio [AOR]: 2.22 [95% confidence interval {CI}: 1.04-4.75]; p = 0.038), who were on HAART for more than 24 months (AOR: 3.07 [95% CI: 1.35-7.01]; p = 0.007), who reported alcohol use (AOR: 5.68 [95%CI: 2.10-15.32]; p = 0.001), who had low general health perceptions (AOR: 3.58 [95%CI: 1.20-10.66]; p = 0.021), and who had high distress (AOR: 3.32 [95%CI: 1.19-9.26]; p = 0.022). This study documents several modifiable risk factors for nonadherence in a clinic population of HIV-infected Indians with substantial HAART experience. Further targeted culturally specific interventions are needed that address barriers to optimal adherence.

Abstract
Cognitive impairment among populations at risk for HIV poses a significant barrier to managing risk behaviors. The impact of HIV and several cofactors, including substance abuse and mental illness, on cognitive function is discussed in the context of HIV risk behaviors, medication adherence, and risk-reduction interventions. Literature suggests that cognitive impairment is intertwined in a close, reciprocal relationship with both risk behaviors and medication adherence. Not only do increased risk behaviors and suboptimal adherence exacerbate cognitive impairment, but cognitive impairment also reduces the effectiveness of interventions aimed at optimizing medication adherence and reducing risk. In order to be effective, risk-reduction interventions must therefore take into account the impact of cognitive impairment on learning and behavior.

Abstract
Prior to the era of highly active anti-retroviral therapy (HAART), cohort studies provided equivocal evidence to support the hypothesis that substance use predicts more rapid HIV disease progression. The present review examined the effects of substance use on HIV disease progression in cohort studies with follow-up that continued into the HAART era. Of the 20 studies included in this review, 16 observed that substance use predicted at least one indicator of HIV disease progression. Ten of the 11 studies that followed participants exclusively in the HAART era observed an effect of substance use on HIV disease progression. Findings across studies indicate that stimulant use promotes more rapid HIV disease progression and the effects of substance use on HIV disease progression can persist after controlling for self-reported HAART non-adherence. Future investigations that examine the bio-behavioral pathways whereby substance use promotes HIV disease progression should include: measures of HIV genotypic and phenotypic resistance, multi-method assessment of adherence, and assessment of co-morbid infections that are more prevalent among substance users. Although further mechanistic research is needed, findings from existing cohort studies have clear clinical implications. Implementing screening, brief intervention and referral to substance abuse treatment in HIV medical care could optimize health outcomes and decrease HIV transmission rates by boosting the effectiveness of "Test and Treat" approaches to HIV prevention.

Abstract
OBJECTIVE To assess the association between incident stressful life events (e.g., sexual and physical assault; housing instability; and major financial, employment, and legal difficulties) and unprotected anal or vaginal sexual intercourse (unprotected sex) among people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (PLWHA). METHODS We assessed incident stressful events and unprotected sex over 27 months in 611 participants in an eight-site, five-state study in the Southeast United States. Using mixed-effects logistic models and separately estimating between-person and within-person associations, we assessed the association of incident stressful events with unprotected sex with all partners, HIV-positive partners, and HIV-negative/serostatus-unknown partners. RESULTS Incident stressful events reported at one third or more of interviews included major illness, injury or accident (non-HIV-related); major illness of a family member/close friend; death of a family member/close friend; financial stresses; and relationship stresses. In multivariable models, each additional moderately stressful event an individual experienced at a given time point above his or her norm (within-person association) was associated with a 24% to 27% increased odds of unprotected sex for each partner type. CONCLUSIONS Risk reduction among PLWHA remains a major focus of efforts to combat the HIV epidemic. Incident stressful events are exceedingly common in the lives of PLWHA and are associated with increased unprotected sex. Efforts to either prevent the occurrence of such events (e.g., financial or relationship counseling) or address their sequelae (e.g., coping skills or other behavioral counseling) may help reduce secondary HIV transmission.

Abstract
Comorbid medical illness is common in patients with chronic hepatitis C (HCV) infection and in methadone treatment (MMT) patients, yet little is known about the impact of medical illness on HCV treatment eligibility. Medical illness and HCV treatment eligibility were compared in a case-control study of 80 MMT patients entering an HCV treatment trial and 80 matched non-MMT patients entering HCV treatment in a gastroenterology clinic. 91% of MMT and 85% of non-MMT patients had chronic medical conditions. Despite similar medical severity ratings, a significantly higher proportion (77%) of non-MMT patients were eligible for HCV treatment than were MMT patients (56%) (p<.01). Specific comorbid medical and psychiatric illness led to ineligibility in only 18% of MMT and 16% of non-MMT patients. However, failure to complete the medical evaluation process was significantly (p<.001) more likely to cause ineligibility among MMT patients (19%) than non-MMT patients (0%).

Abstract
BACKGROUND Benefits of exercise for HIV-infected persons have been documented, although in clinical practice, diminished adherence to exercise limits the effectiveness of this auxiliary treatment. Exercise intervention studies carry the caveat that the results are limited to volunteers with good compliance and completion profiles. OBJECTIVES This study aimed to identify characteristics contributing to adherence vs non-adherence to prescribed supervised 10-week 75-minute aerobic and progressive resistance exercise programme in a clinical setting that requires twice-weekly attendance at the physiotherapy gym. STUDY DESIGN This observational study was comprised of 11 males and 11 females, physician-assessed, HIV seropositive patients referred to exercise programmes in a tertiary multi-disciplinary outpatient service for HIV patients at an urban Teaching Hospital in London (UK). Measurements taken prior to the exercise programme were used as dependent variables and include CD4 count, fitness level, flexibility and perceived physical-, emotional-, functional- and psychological- well-being. Attendance records were categorised into a dichotomous independent variable of adherence based on a natural break that occurred at 8/20 attended sessions. RESULTS Prior-to-treatment differences in perceived physical, functional and psychological well-being exist between adherent and non-adherent patients, but no differences were found in age, CD4 count or fitness level. Perceived well-being explained 55.7% of the variances in attendance. Gender and reason for referral appear to be independent of adherence, whereas ethnicity may play an influential role. CONCLUSION Perceived well-being appears to differentiate between adherent and non-adherent patients. Further studies are required to investigate other psychological characteristics and barriers to maintaining exercise.

Abstract
HIV+ substance-dependent individuals (SDIs) show emotional distress and executive impairment, but in isolation these poorly predict sexual risk. We hypothesized that an executive measure sensitive to emotional aspects of judgment (Iowa Gambling Task; IGT) would identify HIV+ SDIs whose sexual risks were influenced by emotional distress. We assessed emotional distress and performance on several executive tasks in 190 HIV+ SDIs. IGT performance interacted significantly with emotional distress, such that only in better performers were distress and risk related. Our results are interpreted using the somatic marker hypothesis and indicate that the IGT identifies HIV+ SDIs for whom psychological distress influences HIV risk.

Abstract
HIV transmission may be prevented by effectively suppressing viral replication with antiretroviral therapy (ART). However, adherence is essential to the success of ART, including for reducing HIV transmission risk behaviors. This study examined the association of nonadherence versus adherence with HIV transmission risks. Men (n = 226) living with HIV/AIDS and receiving ART completed confidential computerized interviews and telephone-based unannounced pill counts for ART adherence monitoring. Data were collected between January 2008 and June 2009. Results showed that nonadherence to ART was associated with greater number of sex partners and engaging in unprotected and protected anal intercourse. These associations were not moderated by substance use. The belief that having an undetectable viral load leads to lower infectiousness was associated with greater number of partners, including nonpositive partners, and less condom use. Men who had an undetectable viral load and believed that having an undetectable viral load reduces their infectiousness, were significantly more likely to have contracted a recent STI. Programs aimed at testing and treating people living with HIV/AIDS for prevention require attention to adherence and sexual behaviors.

Abstract
Secondary HIV prevention, or "positive prevention," is concerned with reducing HIV transmission risk behavior and optimizing the health and quality of life of people living with HIV/AIDS (PLWHA). The association between mental health and HIV transmission risk (i.e., sexual risk and poor medication adherence) is well established, although most of this evidence is observational. Further, a number of efficacious mental health treatments are available for PLWHA yet few positive prevention interventions integrate mental health treatment. We propose that mental health treatment, including behavioral and pharmacologic interventions, can lead to reductions in HIV transmission risk behavior and should be a core component of secondary HIV prevention. We present a conceptual model and recommendations to guide future research on the effect of mental health treatment on HIV transmission risk behavior among PLWHA.

Abstract
OBJECTIVES We sought to examine behavioral risks and behavior changes associated with testing HIV-positive among sexually transmitted infection (STI) patients, in order to inform HIV- and STI-prevention interventions. METHODS We performed a cohort study of 29 STI patients who seroconverted from HIV-negative to HIV-positive during 1 year of observation and 77 STI patients who persistently tested HIV-negative. Computerized behavioral interviews were collected at baseline and at 1 year, and STI clinic charts were abstracted over the same 1-year period. RESULTS The STI patients who reported genital bleeding during sexual activity at baseline were significantly more likely to test HIV-positive. Reductions in number of sexual partners and rates of unprotected intercourse occurred for all STI clinic patients regardless of whether they tested HIV-positive. CONCLUSIONS Although risk reductions occurred, 5% of HIV-negative STI clinic patients subsequently tested HIV-positive over 1 year. Behavioral risk-reduction interventions are urgently needed for male and female STI clinic patients.

Abstract
Hazardous drinking increases the risk of contracting and transmitting human immunodeficiency virus (HIV). This study aimed to determine the prevalence of HIV testing among hazardous drinkers using the 2006 Behavioral Risk Factor Surveillance System dataset. Adjusted odds ratios were obtained using multivariable logistic regression for the relationship between hazardous drinking and HIV testing. Results indicated that adjusting for confounders, hazardous drinkers (1) had 0.86 (95% CI: 0.84, 0.89) the odds of ever having had an HIV test compared to nonhazardous drinkers. Therefore public health interventions targeted at hazardous drinkers to increase the rate of HIV testing are suggested. The study's limitations are noted.

Abstract
BACKGROUND South Africa has one of the fastest growing HIV epidemics in the world and new infections may often result from people who have tested HIV positive. This study examined the sexual practices and risk behaviours of men and women living with HIV/AIDS being treated for a co-occurring sexually transmitted infection (STI). METHODS A sample of men and women receiving services at three South African STI clinics completed a computer administered behavioural assessment. RESULTS Among the 218 HIV positive STI clinic patients, 34 (16%) had engaged in unprotected vaginal or anal intercourse with uninfected or unknown HIV status sex partners in the previous month. A multivariate logistic regression indicated that unprotected sex with uninfected or unknown HIV status partners was independently associated with older age, female gender, alcohol use, and other drug use, and drug use in sexual contexts. CONCLUSIONS People living with HIV/AIDS who contract co-occurring STI are at significant risk for transmitting HIV to uninfected partners. Positive prevention interventions are urgently needed for South Africa.

Abstract
PURPOSE OF REVIEW To provide a state-of-the-science review of the literature on secondary prevention of HIV infection or 'prevention for positives' (PfP) interventions. RECENT FINDINGS Early work on PfP focused on understanding the dynamics of risky behavior among People Living with HIV/AIDS (PLWH) and on designing, implementing, and evaluating a limited number of interventions to promote safer sexual and drug use behavior in this population (i.e., PfP interventions). Previous meta-analyses demonstrated that PfP interventions can effectively promote safer behavior. However, the understanding of risk dynamics among PLWH and the extant number and breadth of effective PfP interventions were scant. Recent work has addressed some of these problems, yielding greater understanding of risk dynamics and providing additional, effective interventions. Still, only a modest number of recent, rigorously evaluated, effective interventions have been identified. New ideas for creating stronger, more integrated, and effective PfP interventions have emerged that will guide future intervention research and practice. SUMMARY There remains much to be done to understand why, when, and under what conditions PLWH practice risk. Substantial work also needs to be performed to design, implement, rigorously evaluate, and when effective, to disseminate widely, additional, evidence-based PfP interventions targeting diverse populations. Directing such interventions to populations of PLWH at greatest risk for transmission of HIV has the potential to yield significant impact on the pandemic.

Abstract
In the past 25 years, the field of HIV prevention research has been transformed repeatedly. Today, effective HIV prevention requires a combination of behavioral, biomedical, and structural intervention strategies. Risk of transmitting or acquiring HIV is reduced by consistent male- and female-condom use, reductions in concurrent and/or sequential sexual and needle-sharing partners, male circumcision, and treatment with antiretroviral medications. At least 144 behavioral prevention programs have been found effective in reducing HIV transmission acts; however, scale up of these programs has not occurred outside of the United States. A series of recent failures of HIV-prevention efficacy trials for biomedical innovations such as HIV vaccines, treating herpes simplex 2 and other sexually transmitted infections, and diaphragm and microbicide barriers highlights the need for behavioral strategies to accompany biomedical strategies. This challenges prevention researchers to reconceptualize how cost-effective, useful, realistic, and sustainable prevention programs will be designed, delivered, tested, and diffused. The next generation of HIV prevention science must draw from the successes of existing evidence-based interventions and the expertise of the market sector to integrate preventive innovations and behaviors into everyday routines.

Abstract
Neuropsychiatric disorders and syndromes may be underdiagnosed and inadequately treated in individuals infected with HIV. Depression in particular is among the most prevalent diagnoses, and data from controlled clinical studies have shown that antidepressant medications are efficacious and safe for treating depression in HIV-infected persons. A significant shortcoming of this literature is that most of the available data are from studies conducted before the advent of highly active antiretroviral therapy. In addition, apart from antidepressant medications, controlled studies systematically assessing efficacy and safety issues for other classes of psychotropic drugs (e.g., antipsychotic and anxiolytic medications) in HIV-infected persons are lacking. This review summarizes essential findings pertaining to the use of psychotropic medications to treat depression and other neuropsychiatric disorders in the context of HIV. It includes a discussion of clinically relevant treatment considerations (e.g., side effects, drug-drug interactions) derived from the existing literature as well as judgments that clinicians face in the absence of research data. Despite some shortcomings of the existing literature, overall there is compelling evidence that the appropriate use of psychotropic medications (coupled with behavioral therapy) can improve the quality of life of mentally ill HIV-infected individuals.

Abstract
This article provides an overview and reviews the HIV pandemic, the basic biology and immunology of the virus (e.g., genetic diversity of HIV and the viral life cycle), the phases of disease progression, modes of HIV transmission, HIV testing, immune response to the infection, and current therapeutic strategies. HIV is occurring in epidemic proportions, especially in Sub-Saharan Africa. In the US, men who have sex with men account for over half of AIDS diagnoses; racial and ethnic minorities are disproportionally affected. Factors influencing the progression and severity of HIV infection include type of immune response, coinfection (e.g., another sexually transmitted infection, including hepatitis B or C), age and behavioral and psychosocial factors. Antiretroviral therapies can achieve reduction in blood levels of the HIV virus below the limits of detection by current technology. However, effective treatment requires adherence to therapy. Patient failure to adhere to treatment regimens results in detectible circulating virus and in HIV disease progression, and is the primary cause of drug resistance. In addition to research on the immunology and virology of the disease, other studies focus on behavioral and psychosocial factors that may affect medication adherence and risk behaviors.

Abstract
Effective secondary prevention programs to reduce HIV transmission risk-relevant behaviors among HIV-infected individuals must go beyond the traditional, common sense prevention components to develop biomedically and epidemiologically informed behavioral interventions as part of comprehensive, integrated, multidisciplinary HIV care. Incorporating and expanding on the Serostatus Approach to Fighting the Epidemic, a five-pronged strategy set forth by the Centers for Disease Control and Prevention in 2001, we discuss recent findings from the biomedical sciences on viral and host factors that influence infectiousness to support the idea that the most proactive prevention programs will explicitly integrate biomedical interventions and approaches designed to reduce infectiousness, and thus the sexual transmission of HIV. Based on studies of emerging and spreading drug-resistant HIV variants, we have posited the potential development of biodisparity as the biological entrenchment of disparities in socioeconomic status, access to care, and HIV risk-relevant behaviors that differentially affect minorities living with HIV in the US. It is clear that creative approaches based on an expanded behavioral medicine interface with the latest HIV biomedical and epidemiological research are needed to enhance the efficacy of HIV secondary prevention.

Abstract
Despite advances in HIV treatment, there continues to be great variability in the progression of this disease. This paper reviews the evidence that depression, stressful life events, and trauma account for some of the variation in HIV disease course. Longitudinal studies both before and after the advent of highly active antiretroviral therapies (HAART) are reviewed. To ensure a complete review, PubMed was searched for all English language articles from January 1990 to July 2007. We found substantial and consistent evidence that chronic depression, stressful events, and trauma may negatively affect HIV disease progression in terms of decreases in CD4 T lymphocytes, increases in viral load, and greater risk for clinical decline and mortality. More research is warranted to investigate biological and behavioral mediators of these psychoimmune relationships, and the types of interventions that might mitigate the negative health impact of chronic depression and trauma. Given the high rates of depression and past trauma in persons living with HIV/AIDS, it is important for healthcare providers to address these problems as part of standard HIV care.
