Ayoub SM, Libster AM, Barnes SA, Dulawa SC, Young JW. Sex differences in risk-based decision-making and the modulation of risk preference by dopamine-2 like receptors in rats. Neuropharmacology 2024; 248:109851. [PMID: 38325772 PMCID: PMC11227321 DOI: 10.1016/j.neuropharm.2024.109851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/09/2024] [Accepted: 01/22/2024] [Indexed: 02/09/2024]
Abstract
Heightened risk-based decision-making is observed across several neuropsychiatric disorders including schizophrenia, bipolar disorder, and Parkinson's disease, yet no treatments exist that effectively normalize this aberrant behavior. Preclinical risk-based decision-making paradigms have identified the important modulatory roles of dopamine and sex in the performance of such tasks, though specific task parameters may alter such effects (e.g., punishment and reward values). Previous work has highlighted the role of dopamine 2-like receptors (D2R) during performance of the Risk Preference Task (RPT) in male rats, however sex was not considered as a factor in this study, nor were treatments identified that reduced risk preference. Here, we utilized the RPT to determine sex-dependent differences in baseline performance and impact of the D2R receptor agonist pramipexole (PPX), and antagonist sulpiride (SUL) on behavioral performance. Female rats exhibited heightened risk-preference during baseline testing. Consistent with human studies, PPX increased risk-preference across sex, though the effects of PPX were more pronounced in female animals. Importantly, SUL reduced risk-preference in these rats across sexes. Thus, under the task specifications of the RPT that does not include punishment, female rats were more risk-preferring and required higher PPX doses to promote risky choices compared to males. Furthermore, blockade of D2R receptors may reduce risk-preference of rats, though further studies are required.

Virological Outcomes After Switching to Abacavir/Lamivudine/Dolutegravir Combined with Adherence Support in People Living with HIV with Poor Adherence: A Phase IV, Multicentre Randomized Prospective Open Label Study (TriiADD-CTN 286). Patient Prefer Adherence 2022; 16:3267-3281.

Abstract
BACKGROUND Many people living with HIV struggle to consistently adhere to antiretroviral therapy, fail to achieve long-term virologic control and remain at risk for HIV-related disease progression, development of resistance and may transmit HIV infection to others. OBJECTIVE To determine if switching from current multi-tablet (curART) to single-tablet antiretroviral therapy (abacavir/lamivudine/dolutegravir; ABC/3TC/DTG), both combined with individualized adherence support, would improve HIV suppression in non-adherent vulnerable populations. METHODS TriiADD was an investigator-initiated randomized, multicentre, open label study. HIV+ adults with documented non-adherence on curART were randomized in a 1:1 ratio to immediately switch to ABC/3TC/DTG or to continue curART. Both arms received adherence support. The primary outcome was the proportion of participants in each arm with HIV RNA < 50 copies/mL 24 weeks after randomization. RESULTS In total, 50 people were screened and 27 randomized from 11 sites across Canada before the trial was stopped early due to slow recruitment. Participants were predominantly from ethnocultural communities, Indigenous people and/or had a history of injection drug use. The proportion achieving HIV RNA < 50 copies/mL at week 24 was 4/12 (33%) in the curART arm vs 7/13 (54%) in the ABC/3TC/DTG arm; median Bayesian risk difference, 5% (95% CrI, -17 to 28%) higher for those randomized to ABC/3TC/DTG. We encountered difficulties with recruitment of participants without prior drug resistance, retention despite intensive support, reliably measuring adherence and in overcoming entrenched adherence barriers. CONCLUSION Results of our trial are consistent with a slight improvement in viral suppression in a vulnerable population when a single tablet regimen is combined with patient-level adherence support. Beyond treatment simplicity and tolerability, tailored interventions addressing stigma and social determinants of health are still needed. The numerous challenges we encountered illustrate how randomised trials may not be the best approach for assessing adherence interventions in vulnerable populations.

Abstract
Tremendous biomedical advancements in HIV prevention and treatment have led to aspirational efforts to end the HIV epidemic. However, this goal will not be achieved without addressing the significant mental health and substance use problems among people living with HIV (PLWH) and people vulnerable to acquiring HIV. These problems exacerbate the many social and economic barriers to accessing adequate and sustained healthcare, and are among the most challenging barriers to achieving the end of the HIV epidemic. Rates of mental health problems are higher among both people vulnerable to acquiring HIV and PLWH, compared with the general population. Mental health impairments increase risk for HIV acquisition and for negative health outcomes among PLWH at each step in the HIV care continuum. We have the necessary screening tools and efficacious treatments to treat mental health problems among people living with and at risk for HIV. However, we need to prioritize mental health treatment with appropriate resources to address the current mental health screening and treatment gaps. Integration of mental health screening and care into all HIV testing and treatment settings would not only strengthen HIV prevention and care outcomes, but it would additionally improve global access to mental healthcare.

Adherence to antiretroviral therapy in a clinical cohort of HIV-infected children in East Africa. PLoS One 2018; 13:e0191848. [PMID: 29466385 PMCID: PMC5842873 DOI: 10.1371/journal.pone.0191848] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2016] [Accepted: 01/08/2018] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE To describe antiretroviral therapy (ART) adherence and associated factors for a large HIV-infected pediatric cohort followed by sites of the East Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) consortium. METHODS This study utilized prospectively collected clinical data from HIV-infected children less than 13 years of age who initiated ART within 4 clinical care programs (with 26 clinical sites) in Kenya, Uganda, and Tanzania and were followed for up to 6 years. Programs used one of 3 adherence measures, including 7-day quantitative recall, 7-day categorical recall, and clinician pill assessments. We fit a hierarchical, three-level, logistic-regression model to examine adherence, with observations nested within patient, and patients within the 26 sites providing pediatric HIV data to this analysis. RESULTS In East Africa, 3,304 children, 52.0% male, were enrolled in care and were subsequently observed for a median of 92 weeks (inter-quartile range [IQR] 50.3-145.0 weeks). Median age at ART initiation was 5.5 years ([IQR] 3.0-8.5 years). "Good" adherence, as reported by each clinic's measures, was extremely high, remaining on average above 90% throughout all years of follow-up. Longer time on ART was associated with higher adherence (adjusted Odds Ratio-aOR-per log-transformed week on ART: 1.095, 95% Confidence Interval-CI-[1.052-1.150].) Patients enrolled in higher-volume programs exhibited higher rates of clinician-assessed adherence (aOR per log-500 patients: 1.174, 95% CI [1.108-1.245]). Significant site-level variability in reported adherence was observed (0.28), with even higher variability among patients (0.71). In a sub-analysis, being an orphan at the start of ART was strongly associated with lower ART adherence rates (aOR: 0.919, 95% CI [0.864-0.976]). CONCLUSIONS Self-reported adherence remained high over a median of 1.8 years in HIV care, but varied according to patient-level and site-level factors. Consistent adherence monitoring with validated measures and attention to vulnerable groups is recommended.

Abstract
Interventions are needed to address each phase of the HIV care continuum in order to improve health outcomes and reduce likelihood of HIV transmission. The purpose of this study was to assess the impact of a community- and clinic-based intervention designed and implemented to reengage individuals who were lost to HIV care. Eligible participants had either never engaged in HIV care or had not had a medical visit for at least 12 months. Participants enrolled in a community- and clinic-based intervention that included intensive case management, access to a community nurse and peer navigator, as well as emergency stabilization funds. Data were collected at baseline and 6-month time points by the case managers; which included sociodemographics, general health, abstracted HIV viral loads and CD4 cell counts from their medical records. Descriptive and GEE analyses were conducted to assess changes from baseline to 6 months. A total of 322 participants enrolled over a 5-year period, of whom the majority were male (n = 250) and African American with a mean age of 42.0 years. After 6 months of the intervention, there was a significant increase of individuals who had undetectable HIV viral loads and their median CD4 cell counts increased (p < 0.01 for both). General health improved as well (p < 0.01). It is clear that this method of engagement, while staff intensive, is successful at engaging and retaining individuals in HIV care at least through 6 months.

Implementation and Operational Research: A Cost-Effective, Clinically Actionable Strategy for Targeting HIV Preexposure Prophylaxis to High-Risk Men Who Have Sex With Men. J Acquir Immune Defic Syndr 2017; 72:e61-7.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) is effective at preventing HIV infection among men who have sex with men (MSM), but there is uncertainty about how to identify high-risk MSM who should receive PrEP. METHODS We used a mathematical model to assess the cost-effectiveness of using the HIV Incidence Risk Index for MSM (HIRI-MSM) questionnaire to target PrEP to high-risk MSM. We simulated strategies of no PrEP, PrEP available to all MSM, and eligibility thresholds set to HIRI-MSM scores between 5 and 45, in increments of 5 (where a higher score predicts greater HIV risk). Based on the iPrEx, IPERGAY, and PROUD trials, we evaluated PrEP efficacies from 44% to 86% and annual costs from $5900 to 8700. We designate strategies with incremental cost-effectiveness ratio (ICER) ≤$100,000/quality-adjusted life-year (QALY) as "cost-effective." RESULTS Over 20 years, making PrEP available to all MSM is projected to prevent 33.5% of new HIV infections, with an ICER of $1,474,000/QALY. Increasing the HIRI-MSM score threshold reduces the prevented infections, but improves cost-effectiveness. A threshold score of 25 is projected to be optimal (most QALYs gained while still being cost-effective) over a wide range of realistic PrEP efficacies and costs. At low cost and high efficacy (IPERGAY), thresholds of 15 or 20 are optimal across a range of other input assumptions; at high cost and low efficacy (iPrEx), 25 or 30 are generally optimal. CONCLUSIONS The HIRI-MSM provides a clinically actionable means of guiding PrEP use. Using a score of 25 to determine PrEP eligibility could facilitate cost-effective use of PrEP among high-risk MSM who will benefit from it most.

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.

Abstract
Background Inappropriate use of non-prescription remedies by persons living with human immunodeficiency virus (PLHIV) may result in adverse events or potentiate non-adherence to prescribed medications. This study investigated the use of non-prescription remedies among PLHIV receiving antiretroviral therapy (ART) from four treatment centers in southern Ghana. Methods A mixed method design using quantitative and qualitative methods was used. This article focuses on the quantitative survey of 540 respondents. Univariate analysis was used to generate descriptive tabulations of key variables. Bivariate analysis and logistic regression modeling, respectively, produced unadjusted and adjusted associations between background attributes of PLHIV and the use of non-prescription remedies. A p-value of < 0.05 was considered statistically significant. All analyses were performed using IBM SPSS Statistics for Windows, Version 20.0. Results One out of three respondents reported the use of non-prescription remedies at least once within 3 months of the survey. Most of these were locally made and included “Angel natural bitters, concoctions from the Christian prayer centers, garlic, and mahogany syrups.” These remedies were used concomitantly with antiretroviral medications (ARVs)—46% or administered with ARVs but at different times during the day (43%). Some of the remedies were reportedly prescribed by health workers, or self-initiated during periods of ARVs shortage. Others took them based on their perception of their efficacy. Bivariate level analysis identified ART clinic site, place of residence, and ARV adherence monitoring to be significantly associated with the use of non-prescription remedies (p < 0.05). Multiple logistic regression analysis controlling for covariates confirmed the location of ART clinic as the only predictor of the use of non-prescription remedies. Compared to clients at the large urban teaching hospital (Korle-Bu Fevers Unit ART center), those at the district level (Atua ART center) were ninefold more likely to use non-prescription remedies [adjusted odds ratio (AOR) = 8.84; 95% confidence interval (CI) 2.83–33.72]. Those from a district level mission hospital (St. Martin’s ART center) were threefold as likely to use these remedies (AOR = 2.610; 95% CI 1.074–9.120). Conclusion The use of non-prescription remedies by PLHIV on ART is common in southern Ghana. Usage is mostly self-initiated because of perceived efficacy of remedy, and was more common among clients attending rural ART clinics.

Abstract
In some studies, situational factors have been shown to be stronger predictors of condomless sex than individual risk factors. Cross-sectional relationships between condomless anal sex (CAS) with HIV-serodiscordant partners and risk factors across ecological levels (individual, sexual environment) were examined using a sample (N = 60) of HIV-positive men who have sex with men (MSM) who reported multiple recent episodes of CAS. Negative binomial regressions were used to evaluate the association of contextual risk factors (e.g., substance use during sex, transactional sex, public sex, sex at a sex party) with recent condomless sex, controlling for demographics and mental health. Results demonstrated that sexual environment factors, particularly sex under the influence of drugs or alcohol (B = .019, p < .05), transactional sex (B = .035, p < .01), and public sex (B = .039, p < .01) explained a large proportion of the variance in CAS. Only sex at a sex party was not related to CAS (p = .39). For each additional sexual environment in which men engaged, their rates of CAS increased (B = .39, p < .01). Secondary prevention interventions that are tailored to the proximal sexual environment could be maximally effective, particularly if they address substance use and other challenging sexual situations.

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

Abstract
BACKGROUND The objective of this study was to explore the correlates of ever had sex among perinatally HIV-infected (PHIV) adolescents. METHODS A cross-sectional survey of sexual behaviour was conducted with 624 PHIV adolescents living three regions (12 districts) of Uganda. Data was collected on socio demographic characteristics (age, sex, occupation, religion and education status), sexual practices and behaviours (Intimate relationships, sexual intercourse, age of sexual debut, condom use, multiple and concurrent sexual partners), consequences of sexual behaviours (pregnancy and STI's) and life style factors (use of alcohol, psychoactive substances and peer influence). Multivariable logistic-regression was used to ascertain the determinants of sexual activity. RESULTS The majority of PHIV were female (59.3 %) and the mean age of the sample was 16.2 (±2.1) years. The mean age of sexual debut was 15.8 years; 16.2 % (101/624) reported symptoms for sexually transmitted infections (STI) and more than a third (213/624) reported ever had sex.Of these 76.5 % (165/213) used condoms inconsistently; and 49.3 % (105/213) had been pregnant or made someone pregnant. Of those in relationships, 56.3 % (223/396) did not disclose and were not aware of their partners' HIV status. Adolescents aged 15-19 years were more likely to have ever been sexually active (Adjusted odds ratio (AOR) 6.28, 95 % Confidence interval (CI): 2.63-14.99) compared to those aged 10-14 years. Adolescents who were living alone were more likely to have ever been sexually active compared to those living with one or both parents (AOR 4.33, 95 % CI: 1.13-16.62). The odds of being sexually active were lower among adolescents in school compared to those out of school (AOR 0.2, 95 % CI: 0.13-0.30), who had never been treated for STI (compared to those who had never been treated for STI) (AOR 0.19, 95 % 0.11-0.32) and adolescents who never drank alcohol (AOR 0.49, 95 % CI 0.28-0.87). CONCLUSION PHIV adolescents have risky sexual behaviours characterized by being sexually active, inconsistent condom use, and having partners of unknown status. Risk reduction interventions are required to minimize unplanned pregnancies, STI, and HIV transmission by PHIV adolescents.

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

Abstract
OBJECTIVE Evaluate a computerized intervention supporting antiretroviral therapy (ART) adherence and HIV transmission prevention. DESIGN Longitudinal randomized controlled trial. SETTINGS An academic HIV clinic and a community-based organization in Seattle. SUBJECTS In a total of 240 HIV-positive adults on ART, 209 completed 9-month follow-up (87% retention). INTERVENTION Randomization to computerized counseling or assessment only, 4 sessions over 9 months. MAIN OUTCOME MEASURES HIV-1 viral suppression, and self-reported ART adherence and transmission risks, compared using generalized estimating equations. RESULTS Overall, intervention participants had reduced viral load: mean 0.17 log10 decline, versus 0.13 increase in controls, P = 0.053, and significant difference in ART adherence baseline to 9 months (P = 0.046). Their sexual transmission risk behaviors decreased (odds ratio = 0.55, P = 0.020), a reduction not seen among controls (odds ratio = 1.1, P = 0.664), and a significant difference in change (P = 0.040). Intervention effect was driven by those most in need; among those with detectable virus at baseline (>30 copies/mL, n = 89), intervention effect was mean 0.60 log10 viral load decline versus 0.15 increase in controls, P = 0.034. ART adherence at the final follow-up was 13 points higher among intervention participants versus controls, P = 0.038. CONCLUSIONS Computerized counseling is promising for integrated ART adherence and safer sex, especially for individuals with problems in these areas. This is the first intervention to report improved ART adherence, viral suppression, and reduced secondary sexual transmission risk behavior.

Abstract
Contemporary HIV prevention efforts are increasingly focused on those already living with HIV/AIDS (i.e., "prevention with positives"). Key to these initiatives is research identifying the most risky behavioral targets. Using a longitudinal design, we examined socio-demographic and psychosocial factors that prospectively predicted unprotected anal intercourse (UAI) in a sample of 134 HIV-seropositive men who have sex with men (MSM) initiating, changing, or re-starting an antiretroviral therapy regimen as part of a behavioral intervention study. Computer-based questionnaires were given at baseline and 6 months. In a sequential logistic regression, baseline measures of UAI (step 1), socio-demographic factors such as Latino ethnicity (step 2), and psychosocial factors such as crystal methamphetamine use, greater life stress, and lower trait anxiety (step 3) were predictors of UAI at 6 months. Problem drinking was not a significant predictor. Prevention efforts among MSM living with HIV/AIDS might focus on multiple psychosocial targets, like decreasing their crystal methamphetamine use and teaching coping skills to deal with life stress.

Abstract
OBJECTIVE To assess opportunities for transmitted drug resistance (TDR), we examined sexual risk behaviours, HIV viraemia and antiretroviral resistance among patients in care. DESIGN A retrospective, cross-sectional analysis of clinical cohort data. METHODS For 244 UNC Center for AIDS Research HIV Clinical Cohort participants, demographic and behavioural data were obtained during in-person interviews between 2000 and 2011. Genotypic resistance tests were interpreted using WHO surveillance drug resistance mutations (SDRMs). Log-linear binomial regression was used to evaluate associations with TDR risk, defined as unprotected sex in the prior 6 months, HIV RNA at least 400 copies/ml and at least one SDRM. RESULTS Participants included 91 (37%) women and 153 men, of whom 92 (60%) were MSM. Median age was 43 years; 70% were Black (n = 171). Most (97%) were antiretroviral-experienced; 44% had exposure to more than four regimens. Among 204 individuals on antiretrovirals, 42% reported suboptimal adherence and 29% were viraemic. Over half of participants had at least one SDRM (n = 131); 26 (11%) had triple-class resistance. Overall, 70% were sexually active, and 55% used condoms inconsistently. Thirty (12%) reported unprotected sex during periods of drug-resistant viraemia. Higher TDR risk was associated with prior homelessness [adjusted prevalence ratio (aPR) 2.20, 95% confidence interval (CI) 1.16-4.18], active substance use (aPR 3.12, 95% CI 1.47-6.62) and nonsignificantly with MSM (aPR 1.75, 95% CI 0.93-3.28). CONCLUSION A small but significant proportion of clinic patients with drug-resistant HIV engage in sexual behaviours that place others at risk for TDR. Targeted efforts in secondary prevention could have an impact on TDR incidence, over time.

Abstract
Purpose. The purpose of this study was to test the feasibility and assess outcomes of health care adherence based on whether participants engage in particular risky behaviors relevant to general health or living with human immunodeficiency virus (HIV) infection and the frequency of these adherent behaviors. Health adherent behaviors include both self-advocacy and decreased stigma as underlying key components. Design. A randomized control trial comparing peer-led attention control support and intervention groups. Setting. Community-based women's drop-in center in an urban, black neighborhood of Boston, Massachusetts. Subjects. Aging, low-income, black women living with HIV infection. Intervention. Peer-led, small-group, structured writing using film clips from Women's Voices Women's Lives as a writing prompt. Measures. Demographic and outcome data that included adherence, self-advocacy, and stigma; collected at baseline, 6 weeks, and 6 months. Analysis. Repeated-measures analysis of variance scores were examined between groups and waves. Paired-sample t-tests were used to examine mean differences across time. Results. Sample included 110 women (intervention, n = 56; comparison, n = 54). Retention was 85.5%. Repeated-measures analysis indicated intervention group condom use (n = 69, F = 8.02, df = 1, p < .01) and safe sex (n = 71, F = 13.02, df = 1, p < .01) was higher than that of comparison group. A time effect was also found in the Silencing the Self Scale (n = 91, Pillai's trace = 7.21, df = 2, p < .01). Conclusion. This study demonstrates the feasibility of a tailored, peer-led, and culturally relevant interventions and tentative efficacy in populations affected by health disparities. Key limitations include no comparison intervention format with women who can't write and the need to test generalizability.

Abstract
Women living with HIV (WLH) face challenges related to stigma, disclosure of HIV status, and negotiating safer sex. Several effective behavioral interventions, such as Healthy Relationships (HR), help WLH address these challenges and are disseminated by the USA Centers for Disease Control and Prevention's (CDC) Diffusion of Effective Behavioral Interventions project. However, many WLH living in poor urban or rural locations cannot access interventions such as HR because implementation is not feasible. Video-conferencing technology holds promise for expanding access to effective behavioral interventions for WLH. Following a systematic adaptation to the video-conferencing format, this pilot study tested the delivery of HR via video-group (VG) among WLH. The video-conferencing-based intervention, HR-VG, consisted of six, two-hour sessions led by two facilitators, and used structured activities and video-clips to build disclosure and safer sex skills. Four minority WLH received HR-VG at four different community-based intervention sites in a private room equipped with a video-phone for participating in HR-VG and a desktop computer for completing assessments via Audio Computer-Assisted Self Interview. Participants completed a baseline assessment prior to HR-VG and post-session assessment after each HR-VG session. The post-intervention assessment and video-focus group were completed following the last HR-VG session. Facilitators completed an assessment after each HR-VG session and an open-ended questionnaire following HR-VG. HR-VG was implemented in its entirety with minimal challenges. Both participants and facilitators reported feeling either "very comfortable" or "completely comfortable" with the technology and the overall intervention. Participants also reported high levels of unity and togetherness among the group. These preliminary findings suggest VG delivery of HR for WLH is both feasible and highly valued by participants. A follow-up randomized controlled trial is under way to test the feasibility and efficacy of HR-VG with a larger sample of WLH.

Abstract
OBJECTIVES To characterise the experiences of heterosexual men and women living with HIV postdiagnosis and explain these experiences in relation to their identity and sexuality. DESIGN Qualitative study using in-depth interviews and a theoretically informed biographic disruption theory. SETTING Interviews were conducted in two Nairobi slums (Kenya). PARTICIPANTS 41 HIV-infected heterosexual men and women aged 18 years or older. RESULTS People living with HIV have divergent experiences surrounding HIV diagnosis. Postdiagnosis, there are multiple phases of identity transition, including status (non-)disclosure, and attempts at identity repair and normalcy. For some people, this process involves a transition to a new self-identity, incorporating both HIV and antiretroviral treatment (ART) into their lives. For others, it involves a partial transition, with some aspects of their prediagnosis identity persisting, and for others it involves a rejection of HIV identity. Those people who were able to incorporate HIV/AIDS in their identity, without it being disruptive to their biography, were pursuing safer sexual and reproductive lives. By contrast, those people with a more continuous biography continued to reflect their prediagnosis identity and sexual behaviour. CONCLUSIONS People living with HIV/AIDS (PLWHA) had to rework their sense of identity following diagnosis in the context of living in a slum setting. Men and women living with HIV in slums are poorly supported by health systems and services as they attempt to cope with a diagnosis of HIV. Given the availability of ART, health services and professionals need to support the rights of PLWHA to be sexually active if they want to and achieve their fertility goals, while minimising HIV transmission risk.

Abstract
Recent findings highlight the continued rise in cases of HIV infection among racial/ethnic minority young men who have sex with men (YMSM). In adults, disclosure of HIV status has been associated with decreased sexual risk behaviors but this has not been explored among YMSM. In this study of 362 HIV-infected racial/ethnic minority YMSM, rates of disclosure were high, with almost all disclosing their status to at least one person at baseline. The majority had disclosed to a family member, with higher disclosure rates to female relatives compared with males. After adjustment for site, disclosure to sex partners and boyfriends was associated with an increase in condom use during both oral and anal sex. Future studies should consider skills training to assist youth in the disclosure process, facilitate how to determine who in their family and friend social network can be safely disclosed to and support family-based interventions.

Abstract
BACKGROUND Factors associated with initiation of sexual activity among perinatally human immunodeficiency virus (HIV)-infected (PHIV(+)) youth, and the attendant potential for sexual transmission of antiretroviral (ARV) drug-resistant HIV, remain poorly understood. METHODS We conducted cross-sectional and longitudinal analyses of PHIV(+) youth aged 10-18 years (mean, 13.5 years) enrolled in the US-based Pediatric HIV/AIDS Cohort Study between 2007 and 2009. Audio computer-assisted self-interviews (ACASI) were used to collect sexual behavior information. RESULTS Twenty-eight percent (95% confidence interval [CI], 23%-33%) (92/330) of PHIV(+) youth reported sexual intercourse (SI) (median initiation age, 14 years). Sixty-two percent (57/92) of sexually active youth reported unprotected SI. Among youth who did not report history of SI at baseline, ARV nonadherence was associated with sexual initiation during follow-up (adjusted hazard ratio, 2.87; 95% CI, 1.32-6.25). Youth living with a relative other than their biological mother had higher odds of engaging in unprotected SI than those living with a nonrelative. Thirty-three percent of youth disclosed their HIV status to their first sexual partner. Thirty-nine of 92 (42%) sexually active youth had HIV RNA ≥5000 copies/mL after sexual initiation. Viral drug resistance testing, available for 37 of these 39 youth, identified resistance to nucleoside reverse transcriptase inhibitors in 62%, nonnucleoside reverse transcriptase inhibitors in 57%, protease inhibitors in 38%, and all 3 ARV classes in 22%. CONCLUSIONS As PHIV(+) youth become sexually active, many engage in behaviors that place their partners at risk for HIV infection, including infection with drug-resistant virus. Effective interventions to facilitate youth adherence, safe sex practices, and disclosure are urgently needed.

Abstract
Serostatus disclosure is an important component of secondary HIV prevention with potential benefits for both the individual by experiencing increased social support and society by reducing HIV transmission risk behaviors. This cross-sectional study assessed disclosure patterns to sex partners, family members, and friends by sociodemographic and HIV-related factors among an urban, Midwestern U.S. HIV clinic population (n = 809); a majority of whom were African American and male with a mean age of 41 years. Almost three quarters (n = 596) of the sample was currently receiving HIV therapy, with 68% (n = 404) successfully suppressing their HIV viral loads. Among sexually activity individuals, 97% reported disclosing their serostatus to sex partners. This high rate of disclosure to sex partners suggests that social desirability may play a role in this self-reported measure. Approximately half of the sample (n = 359) disclosed to at least one family member and 60% (n = 474) disclosed to at least one friend. Disclosing to family members occurred more often among participants who were unemployed and endorsed depressive disorder symptoms (p < 0.05 for all). Disclosing to friends occurred more frequently among women, Caucasians and those who completed higher levels of education (p < 0.001 for all). HIV disclosure and disease severity were unassociated. Given the chronic nature of HIV care, additional research is needed to develop interventions to facilitate timely disclosure of HIV serostatus.

Sexual protection behavior in HIV-positive gay men: testing a modified information-motivation-behavioral skills model. ARCHIVES OF SEXUAL BEHAVIOR 2011; 40:817-827. [PMID: 20878223 DOI: 10.1007/s10508-010-9682-4] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2009] [Revised: 08/04/2010] [Accepted: 08/04/2010] [Indexed: 05/29/2023]
Abstract
This study on determinants of sexual protection behavior among HIV-positive gay men used the empirically tested information-motivation-behavioral skills (IMB) model. HIV-specific variables were added to the model to determine factors decisive for condom use with steady and casual partners. Data were collected using an anonymous, standardized self-administered questionnaire. Study participants were recruited at HIV outpatient clinics associated with the Eurosupport Study Group and the Swiss HIV Cohort Study. To identify factors associated with condom use, backward elimination regression analyses were performed. Overall, 838 HIV-infected gay men from 14 European countries were included in this analysis. About 53% of them reported at least one sexual contact with a steady partner; 62.5% had sex with a casual partner during the last 6 months. Forty-three percent always used condoms with steady partners and 44% with casual partners. High self-efficacy and subjective norms in favor of condom-use were associated with increased condom use with casual and steady partners, whereas feeling depressed was associated with decreased condom use with casual partners. Condoms were used less often with HIV-positive partners. Self-efficacy as an important behavioral skill to perform protection behavior was influenced by lower perceived vulnerability, higher subjective norms, and more positive safer sex attitudes. The IMB-model constructs appeared to be valid; however, not all the model predictors could be determined as hypothesized. Besides the original IMB constructs, HIV-specific variables, including sexual partners' serostatus and mental health, explained condom use. Such factors should be considered in clinical interventions to promote "positive prevention."

Abstract
We present the results of a clinical trial that tested the efficacy of using motivational interviewing (MI) in a group format to promote adherence to antiretroviral medications and risk reduction behaviors (RRB) in 203 predominately African American HIV infected women. It was compared to a group health promotion program. Participants were followed for 9 months. Adherence was measured by MEMS(®); and RRB by self-report. Controlling for recruitment site and years on ART, no significant group by time effects were observed. Attendance (≥7/8 sessions) modified the effects. Higher MI attendees had better adherence at all follow-ups, a borderline significant group by time effect (p = 0.1) for % Doses Taken on Schedule, a significantly larger proportion who reported abstinence at 2 weeks, 6, and 9 months, and always used protection during sex at 6 and 9 months. Though not conclusive, the findings offer some support for using MI in a group format to promote adherence and some risk reduction behaviors when adequate attendance is maintained.

Abstract
Abstract The purpose of this study was to determine if there was a connection between adherence to antiretroviral therapy (ART) and use of risk reduction behaviors (RRB) in HIV-infected women who were prescribed antiretroviral therapy. The sample consisted of 193 predominately African American women with an average age of 44 who had been on ARV for approximately 9 years and had low annual incomes. All women were participating in a behavioral clinical trial focused on these dual outcomes. Using a risk index developed for this study, we examined the relationship of a composite of risk behaviors to electronically measured and self-reported adherence over the approximately 13-month study period. Women were categorized based on levels of adherence and risky behaviors, and we sought to determine if these classifications were associated with clinical outcomes of HIV viral load and CD4 counts. High levels of adherence were correlated with low risk behaviors (abstinence, consistent use of condoms, etc.). Those classified as high adherence and low-risk behavior (HALR) as well as those classified as high adherence and high-risk behavior (HAHR) had lower mean viral loads and higher CD4 counts than those in the other categories. Women in the low adherence and high-risk category (LAHR) had detectable viral loads and the lowest CD4 counts and are at higher risk for transmitting HIV to partners and unborn children. Our findings underscore the importance of addressing adherence to both ART and RRB in HIV clinical settings to improve clinical outcomes and reduce HIV transmission.

Abstract
Greater understanding of the mechanisms (mediators) by which behavioral-change interventions work is critical to developing theory and refining interventions. Although systematic reviews have been advocated as a method for exploring mediators, this is rarely done. One challenge is that intervention researchers typically test only two paths of the mediational model: the effect of the intervention on mediators and on outcomes. The authors addressed this challenge by drawing information not only from intervention studies but also from observational studies that provide data on associations between potential mediators and outcomes. They also reviewed qualitative studies of participants' perceptions of why and how interventions worked. Using data from intervention (n = 37) and quantitative observational studies (n = 55), the authors conducted a meta-analysis of the mediation effects of eight variables. Qualitative findings (n = 6) contributed to more in-depth explanations for findings. The methods used have potential to contribute to understanding of core mechanisms of behavioral-change interventions.

Abstract
BACKGROUND Outbreaks of sexually transmitted hepatitis C virus (HCV) infection have been reported among human immunodeficiency virus (HIV)-infected men who have sex with men in Europe, Australia, and New York. Whether this is occurring across the United States is unknown. METHODS We determined incidence of HCV infection during 1996-2008 among male participants of the AIDS Clinical Trial Group Longitudinal Linked Randomized Trials cohort, a long-term study of HIV-infected persons randomized into selected US-based clinical trials. We evaluated associations with self-reported injection drug use (IDU), time-varying CD4(+) cell count, and HIV RNA level with use of multivariate Poisson regression. No sexual or non-IDU risk factor data was available. RESULTS A total of 1830 men had an initial negative HCV antibody test result and at least 1 subsequent HCV antibody test result, contributing >7000 person-years. At the time of the initial negative HCV antibody test result, 94% of men were receiving highly active antiretroviral therapy (HAART) and 6% reported current or prior IDU. Thirty-six seroconverted, with overall incidence of .51 cases per 100 person-years (95% confidence interval, .36-.70). Mean age at seroconversion was 46 years. Seroconversion was associated with IDU (25% of seroconverters reported IDU history vs 5% of nonseroconverters; P < .001), whereas 75% (n = 27) of seroconverters reported no IDU (incidence, 2.67 cases per 100 person-years among IDUs, .40 cases per 100 person-years among non-IDUs). Seroconversion was associated with HIV RNA level >400 copies/mL (44% at time of antibody positivity vs 21% at time of last negative antibody test result; P = .02) but not with CD4(+) cell count. CONCLUSIONS Incident HCV infection occurs in HIV-infected men involved in US HIV therapeutic trials, primarily through nonparenteral means, despite engagement in care and HAART. HCV antibody development was not related to immune status but was associated with inadequate HIV suppression. At-risk HIV-infected persons should have access to HCV surveillance.

Abstract
Advances in HIV treatment have generated optimistic beliefs about HIV transmission risk and sexually transmitted infection vulnerability, which can influence motivation to practice safer sex. This study sought to better understand the relationships between these beliefs and different types of sexual risk behavior. A second objective was to determine the association between treatment adherence and sexual risk behaviors. Data collected from 842 HIV-positive men who have sex with men on treatment were examined. Eleven questions measured beliefs regarding HIV transmission risk and vulnerability to other infections or negative health outcomes. The main outcomes were concordant and discordant unprotected anal sex with main and non-main male partners. Thirty-four percent reported concordant and 41% reported discordant unprotected anal sex in the past three months: 26% reported discordant insertive unprotected anal sex. In all multivariate logistic regression models predicting sexual risk behaviors, at least one belief item remained statistically significant. Different patterns of associations between beliefs and sexual risk were observed across partner type and serostatus. Compared to transmission risk beliefs, more vulnerability beliefs were associated with sexual risk. Missing at least one treatment dose in the past month was associated with concordant and discordant sexual risk with non-main partners, while intentionally missing a dose was associated with only discordant risk with non-main partners. Post hoc moderator analysis explored potential interaction between beliefs and adherence. The belief that a low viral load lowers transmission risk was positively associated with discordant sex with non-main partners only among those who missed a dose intentionally. These results underscore the complex relationship between HIV transmission risk and vulnerability beliefs and sexual behavior with different types of partners. Prevention programs should carefully consider how to craft and tailor messages about medical advances while at the same time reinforcing the need for continued sexual safety.

Abstract
Background Individuals with a self-reported history of sexually transmitted infection (STI) are at high risk for depression. However, little is known about how social support affects the association between STI and depression among young women in Canada. Methods Data were drawn from the Canadian Community Health Survey (CCHS), conducted in 2005. A total of 2636 women aged 15–24 years who provided information on STI history were included in the analysis. Depression was measured by a depression scale based on the Composite International Diagnostic Interview Short-Form (CIDI-SF). The 19-item Medical Outcomes Study (MOS) Social Support Survey assessed functional social support. A log-binomial model was used to estimate the prevalence ratio (PR) for self-reported STI history associated with depression and to assess the impact of social support on the association. Results The adjusted PR for self-reported STI history associated with depression was 1.61 (95% CI, 1.03 to 2.37), before social support was included in the model. The association between STI history and depression was no longer significant when social support was included in the model (adjusted PR, 1.28; 95% CI, 0.83 to 1.84). The adjusted PRs for depression among those with low and intermediate levels of social support versus those with a high level of social support were 5.62 (95% CI, 3.50 to 9.56) and 2.19 (1.38 to 3.68), respectively. Conclusions Social support is an important determinant of depression and reduces the impact of self-reported STI on depression among young women in Canada.

Abstract
Some persons living with HIV/AIDS (PLWHA) engage in periods of sexual abstinence. Baseline data from a larger study of homeless/unstably housed PLWHA indicated that 20% (125/644) intentionally abstained from sex in the past 90 days. Reasons included: (1) 'not interested' (n = 78); (2) did not want to infect someone (n = 46); and (3) did not have a partner (n = 37). Abstinence was less likely among all who had a main partner. Among men who have sex with men (MSM), abstinence was less likely among those with a detectable viral load. It was more likely among heterosexual men who were experiencing current housing problems and who had at least a high school education. Among women, abstinence was less likely among African Americans and those whose social networks were more aware of their HIV status. Better understanding of motivations to abstain may improve how programs serving PLWHA address this issue.

Abstract
Since the start of the HIV epidemic we have witnessed significant advances in our understanding of the impact of HIV disease worldwide. Furthermore, breakthroughs in treatment and the rapid expansion of HIV care and treatment programmes in heavily impacted countries over the past 5 years are potentially critical assets in a comprehensive approach to controlling the continued spread of HIV globally. A strategic approach to controlling the epidemic requires continued and comparable expansion and integration of care, treatment and prevention programmes. As every new infection involves transmission, whether vertically or horizontally, from a person living with HIV/AIDS (PLWHA), the integration of HIV prevention into HIV care settings has the potential to prevent thousands of new infections, as well as to improve the lives of PLWHA. In this paper, we highlight how to better utilize opportunities created by the antiretroviral roll-out to achieve more effective prevention, particularly in sub-Saharan Africa. We offer specific recommendations for action in the domains of healthcare policy and practice in order better to utilize the advances in HIV treatment to advance HIV prevention.

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
Research on disclosure among heterosexual adult person(s) living with HIV (PLH) was reviewed, omitting disclosure of parental HIV to children. Disclosure has been studied within five additional relational contexts: with partners, family members, friends, healthcare professionals and in work settings. Disclosure is higher among women than men, among Latino and white compared to African-American families, and among younger compared to older HIV-positive adults. Most PLH disclose to their sexual partners and family members, yet there is a significant minority who do not disclose. Similarly, rates of disclosure to employers range from 27-68%, suggesting broad variability in perceived consequences of employment disclosures. Of concern, 40% of PLH do not consistently disclose to their healthcare professionals. Rather than examine HIV disclosures in the context of relationships, it is possible to understand disclosures around personal identity. Disclosure decisions are often made to tell everyone (making HIV status a central attribute of one's identity), no one (requiring strategies for securing social support while remaining anonymous) or some people (requiring strategic decisions based on context). Given that disclosure decisions are central to personal identity, future data on disclosure and interventions designed to increase disclosure or comfort with disclosure must focus on communication strategies adopted by PLH to present a coherent identity.

Abstract
HIV prevention has become a new priority for HIV clinicians, as their patients live longer and more sexually active lives. Prevention interventions can be effective in clinical settings, but first patients must be screened and inconsistent condom use must be disclosed. Audio computer-assisted self-interviews (ACASI) are an effective way to elicit this sensitive information. We assessed condom use by ACASI among 198 English- or Spanish-speaking HIV patients at 2 community hospital-based HIV clinics in Queens and the Bronx, New York. Among 120 patients reporting sex with a regular partner in the past 4 weeks, 41 (34%) reported not using a condom every time and 22 (18%) reported never using a condom. Among 81 reporting sex with a casual partner in the past 4 weeks, 21 (26%) reported not using a condom every time and 12 (15%) reported never using a condom. Overall, 24 of 129 sexually active patients (19%) reported never using a condom. In a multivariable model controlling for age, race/ethnicity, gender, and HIV exposure category, depression symptoms (Center for Epidemiological Studies Depression Scale [CES-D] score >/= 16; p = 0.03) and self-reported antiretroviral medication non-adherence (</=95% doses in past 3 days; p = 0.03) were significantly associated with never using a condom with a regular or casual partner. ACASI interviews may be an effective way of identifying patients in clinical settings who require prevention counseling as well as other psychosocial services.

Abstract
OBJECTIVE A substantial minority of HIV-positive individuals have comorbid affective or substance use disorders, which can interfere with effective medical management. The present study examined the associations among affect regulation, substance use, non-adherence to anti-retroviral therapy (ART), and immune status in a diverse sample of HIV-positive persons. METHODS A total of 858 HIV-positive participants self-reporting risk of transmitting HIV were enrolled in a randomized behavioral prevention trial and provided baseline blood samples to measure T-helper (CD4+) counts and HIV viral load. RESULTS Among individuals on ART, regular stimulant users had a five-fold (0.70 log10) higher HIV viral load than those who denied regular stimulant use. The association between regular stimulant use and elevated HIV viral load remained after accounting for demographics, differences in CD4+ counts, and polysubstance use. In the final model, 1 unit increase in affect regulation (decreased severity of depressive symptoms as well as enhanced positive states of mind) was associated with a 23% decrease in the likelihood of reporting regular stimulant use and 15% decrease in the likelihood of being classified as nonadherent to ART. Regular stimulant users, in turn, were more than twice as likely to be nonadherent to ART. Even after accounting for the effects of nonadherence and CD4+ counts, regular stimulant use was independently associated with 50% higher HIV viral load. CONCLUSIONS Increased mental health treatment as well as more intensive referrals to substance abuse treatment or 12-step self-help groups may be crucial to assist stimulant users with more effectively managing treatment for HIV/AIDS.
