Willingness to Use Long-Acting Injectable PrEP Among PrEP Naïve Black and Hispanic Sexual Gender Minority Persons

In December 2021, long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was approved for the prevention of HIV in at-risk adults and adolescents. LAI-PrEP may address adherence issues of daily oral daily PrEP and PrEP stigma. However, studies assessing LAI-PrEP willingness among PrEP naive Black and Hispanic sexual and gender minority (SGM) persons- a group disproportionately impacted by the HIV epidemic in the United States - is rare. To assess the extent of and characteristics of willingness to use LAI-PrEP in a national sample of Black and Hispanic SGM who are self-reported that they have never used PrEP. We analyzed data from a national sample of Black and Hispanic SGM collected between March and August 2020. We used log-binomial regression models to assess characteristics associated with willingness to use LAI-PrEP. Of the overall sample (N = 380), the mean age was 24 (SD = 2.8) and the majority of the sample (54%, n = 205) reported willingness to use LAI-PrEP. In multivariable log-binomial regression models, PrEP stigma was independently associated with less [prevalence ratio (PR) = 0.7, 95% confidence interval (CI) = 0.6, 0.9], while number of sexual partners in the past 12 months was associated with a more willingness to use LAI-PrEP (PR = 1.1, 95% CI = 1.0, 1.2). Our findings highlight the persistence of PrEP stigma as a potential barrier to willingness to use LAI-PrEP in this sample of Black and Hispanic SGM who have never used PrEP. Additional work needs to be done to reduce PrEP stigma more broadly.

Co-occurring mental health and drug use experiences among Black and Hispanic/Latino sexual and gender diverse individuals

Black and Hispanic/Latino sexual and gender diverse individuals disproportionately experience overlapping health disparities, such as drug use and elevated depressive symptoms, which are often driven by minority stressors. We sought to better understand the interaction between drug use and mental health, as it may be fruitful in developing effective interventions to address co-occurring health disparities. In a longitudinal, 5-wave sample of 300 Black and Hispanic/Latino sexual and gender diverse (SGD) individuals collected between March 2020 and March 2022, we found a within-person association between greater than average levels of psychological distress (depression and anxiety) and more frequent extra-medical use of cannabis, inhalants, methamphetamines, and opioids over the span of two years. These associations held after adjusting for the direct, within-person association of internalized homonegativity with drug use frequency. These results suggest that psychological distress explains at least some variance in drug use among Black and Hispanic/Latino SGD individuals. This highlights the importance of interventions that focus on mental health among Black and Hispanic/Latino SGD individuals who report drug use.

Leveraging the Black Girls Run Web-Based Community as a Supportive Community for Physical Activity Engagement: Mixed Methods Study

BACKGROUND

About 59%-73% of Black women do not meet the recommended targets for physical activity (PA). PA is a key modifiable lifestyle factor that can help mitigate risk for chronic diseases such as obesity, diabetes, and hypertension that disproportionately affect Black women. Web-based communities focused on PA have been emerging in recent years as web-based gathering spaces to provide support for PA in specific populations. One example is Black Girls Run (BGR), which is devoted to promoting PA in Black women.

OBJECTIVE

The purpose of this study was to describe the content shared on the BGR public Facebook page to provide insight into how web-based communities engage Black women in PA and inform the development of web-based PA interventions for Black women.

METHODS

Using Facebook Crowdtangle, we collected posts (n=397) and associated engagement data from the BGR public Facebook page for the 6-month period between June 1, 2021, and December 31, 2021. We pooled data in Dedoose to analyze the qualitative data and conducted a content analysis of qualitative data. We quantified types of posts, post engagement, and compared post types on engagement: "like," "love," "haha," "wow," "care," "sad," "angry," "comments," and "shares."

RESULTS

The content analysis revealed 8 categories of posts: shout-outs to members for achievements (n=122, 31%), goals or motivational (n=65, 16%), announcements (n=63, 16%), sponsored or ads (n=54, 14%), health related (n=47, 11%), the lived Black experience (n=23, 6%), self-care (n=15, 4%), and holidays or greetings (n=8, 2%). The 397 posts attracted a total of 55,354 engagements (reactions, comments, and shares). Associations between the number of engagement and post categories were analyzed using generalized linear models. Shout-out posts (n=22,268) elicited the highest average of total user engagement of 181.7 (SD 116.7), followed by goals or motivational posts (n=11,490) with an average total engagement of 160.1 (SD 125.2) and announcements (n=7962) having an average total engagement of 129.9 (SD 170.7). Significant statistical differences were found among the total engagement of posts (χ72=80.99, P<.001), "like" (χ72=119.37, P<.001), "love" (χ72=63.995, P<.001), "wow" (χ72=23.73, P<.001), "care" (χ72=35.06, P<.001), "comments" (χ72=80.55, P<.001), and "shares" (χ72=71.28, P<.001).

CONCLUSIONS

The majority of content on the BGR Facebook page (n=250, 63%) was focused on celebrating member achievements, motivating members to get active, and announcing and promoting active events. These types of posts attracted 75% of total post engagement. BGR appears to be a rich web-based community that offers social support for PA as well as culturally relevant health and social justice content. Web-based communities may be uniquely positioned to engage minoritized populations in health behavior. Further research should explore how and if web-based communities such as BGR can be interwoven into health interventions and health promotion.

A comparison of the physical demands associated with various right-angle direct-current power tools

This work examined the physical demands associated with 4 commercially available direct current right-angle power tools along with their computer controlled fastening strategies. Physical demands were measured via an external instrumented handle that could also control the trigger of each tool. Data revealed that forces recorded by the external handle for each of the 4 tools differed. Independent of Joint-Hardness and Target Torque the Atlas Copco TurboTight® and Cleco Low Torque Reaction fastening strategies, both using a rapid spindle-head rotation strategy, produced the lowest peak and impulse force, respectfully, when compared to the 2 tools that were designed to fasten with a longer duration. This work has shown that short duration fastening strategies provide an ergonomics benefit to the users as it requires less force to operate, such force reduction in previous research has been linked to reduced handle displacement and lower muscle effort.

Physical demands associated with right-angle direct-current power-tools: An evaluation of current technology

The purpose of this work was to evaluate the physical demands associated with three direct current powered right-angle power tool tightening strategies at various fastener-location-orientations, target torques and joint-hardness. Physical demands were measured using surface electromyography, handle force and upper body kinematics. Results identified TurboTight®, a rapid and short duration fastening strategy, to produce lower handle force impulse, less joint angle displacement, and lower EMG magnitudes when compared to the longer duration fastening strategies tested. The reduced magnitudes associated with TurboTight®, independent of fastener-location-orientations, target torques and joint-hardness, indicate a lower physical demand on power tool operators, providing a significant ergonomic benefit when compared to the slower fastening strategies.

Substance Use Among a National Sample of Sexual and Gender Minority Adolescents: Intersections of Sex Assigned at Birth and Gender Identity

Purpose: We examined how substance use differed as a function of sex assigned at birth and gender identity (cisgender, transgender, or nonbinary/genderqueer) by type of substance. We sought to test whether current gender identity and sex assigned at birth were key factors in substance use among a large contemporary sample that included transgender and nonbinary/genderqueer adolescents. Methods: We analyzed data from a large national U.S. sample of sexual and gender minority (SGM) adolescents (n = 11,129) collected between April and December 2017. Chi-square tests of independence were used to test whether substance use behaviors varied by sex assigned at birth and gender identity. A series of multivariate logistic regression models tested the odds of substance use by sex assigned at birth and gender identity, as well as the interaction between sex assigned at birth and gender identity. Results: More than half of our sample reported lifetime alcohol use, and one-fourth of the sample reported lifetime marijuana use. Adolescents assigned male at birth had higher prevalence of substance use compared with adolescents assigned female at birth (AFAB). Multivariate models elucidated greater risk for most substance use outcomes for transgender adolescents compared with cisgender adolescents. We found significant interaction effects between gender identity and sex assigned at birth for recent alcohol use and lifetime and recent cigarette use among adolescents AFAB. Conclusions: These findings have implications for stakeholders who develop nationally representative surveys, researchers who examine substance use disparities among SGM adolescents, and mental health professionals who treat underage substance use among vulnerable populations.

Identical and Nonidentical Twins: Risk and Factors Involved in Development of Islet Autoimmunity and Type 1 Diabetes

OBJECTIVE

There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings.

RESEARCH DESIGN AND METHODS

Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years.

RESULTS

At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects.

CONCLUSIONS

Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Sexual Identity Disclosure and Awareness of HIV Prevention Methods Among Black Men Who Have Sex With Men

Black men who have sex with men (BMSM) are disproportionately affected by the human immunodeficiency virus (HIV) epidemic, yet we know little about how HIV-negative BMSM of different sexual orientations access HIV prevention strategies. Identity development, minority stress, and disclosure theories suggest that for people of different sexual orientations, disclosure of sexual identity may be related to health behaviors. We performed a latent class analysis on a sample of 650 BMSM (Mage = 33.78, SD = 11.44) from Atlanta, Georgia, to explore whether sexual orientation, disclosure of sexual identity, and relationship status were related to HIV prevention strategies, including awareness of PrEP (pre-exposure prophylaxis) and PEP (post-exposure prophylaxis) and frequency of HIV testing. We found three distinct BMSM classes referred to as (1) closeted bisexuals, (2) sexual identity managers, and (3) gay, out, and open; all classes primarily engaged in casual sex. Classes differed in their awareness and access to HIV prevention strategies. The closeted bisexual class was least aware of and least likely to access HIV prevention. Findings have important implications for future research, namely the consideration of sexual identity and disclosure among BMSM. With this knowledge, we may be able to engage BMSM in HIV/sexually transmitted infection (STI) prevention services.

Sexual Health, Mental Health, and Beliefs About Cancer Treatments Among Women Attending a Gynecologic Oncology Clinic

Introduction

Sexual health is an important, yet overlooked, aspect of quality of life for gynecologic oncologic patients. Although patients with gynecologic cancer frequently report sexual health concerns, there are limited efforts to address these problems. A comprehensive understanding of the relationship between mental health and sexual health needs to be prioritized.

Aim

To examine multiple components of sexual health in patients with gynecologic cancer.

Methods

For the present study, sexual health concerns (ie, sexual frequency, desire, response, and satisfaction; orgasm; and pain during sex; independent variables), beliefs about cancer treatments affecting sexual health (dependent variable), and mental health (ie, anxiety and depressive symptoms; dependent variables) of patients at a US gynecologic oncology clinic were assessed.

Main Outcome Measures

Demographics; cancer diagnosis; positive screening results for cancer; sexual health histories including sexual frequency, desire, pain, orgasm, responsiveness, and satisfaction; and mental health including depression and anxiety symptoms.

Results

Most women reported experiencing at least one sexual health concern, and half the women screened positive for experiencing symptoms of depression and anxiety. Forty-nine percent of participants reported having no or very little sexual desire or interest in the past 6 months. Further, in mediation analyses, pain during sex was significantly and positively correlated with depressive symptoms (r = 0.42, P < .001), and this relationship was fully mediated by believing that cancer treatments affected one's sexual health (B = 0.16, 95% confidence interval = 0.01–0.48, P < .05).

Conclusion

Findings emphasize the need to further address and incorporate sexual and mental health into standard care for patients attending gynecologic oncology clinics. Screening women for whether and to what extent they perceive cancer treatments affecting their sexual health could provide a brief, easily administrable, screener for sexual health concerns and the need for further intervention. Intervention development for patients with gynecologic cancer must include mental health components and addressing perceptions of how cancer treatments affect sexual health functioning.

Geospatial Indicators of Space and Place: A Review of Multilevel Studies of HIV Prevention and Care Outcomes Among Young Men Who Have Sex With Men in the United States

Young men who have sex with men (YMSM), particularly YMSM who are racial/ethnic minorities, are disproportionately affected by the human immunodeficiency virus (HIV) epidemic in the United States. These HIV disparities have been linked to demographic, social, and physical geospatial characteristics. The objective of this scoping review was to summarize the existing evidence from multilevel studies examining how geospatial characteristics are associated with HIV prevention and care outcomes among YMSM populations. Our literature search uncovered 126 peer-reviewed articles, of which 17 were eligible for inclusion based on our review criteria. Nine studies examined geospatial characteristics as predictors of HIV prevention outcomes. Nine of the 17 studies reported HIV care outcomes. From the synthesis regarding the current state of research around geospatial correlates of behavioral and biological HIV risk, we propose strategies to move the field forward in order to inform the design of future multilevel research and intervention studies for this population.

The cumulative effect of risk compensation on infection preventive measures

We study several epidemic models (with and without gender structure) that incorporate risk compensation behavior in response to a lower chance of acquiring the infection as a result of preventive measures that are only partially effective. We show that the cumulative risk compensation that occurs between a high risk susceptible and infectious individual may play an important role in whether the implementation of these measures is successful in lowering the epidemic reproductive number. In addition, we show that certain levels of risk compensation may cancel the benefit of the low infection risk practiced by diagnosed infectious individuals when the goal is a reduction of the epidemic reproductive number.

Medication beliefs mediate the association between medical mistrust and antiretroviral adherence among African Americans living with HIV/AIDS

Medical mistrust is a significant barrier to medication adherence among African Americans living with HIV. In this study 380 African American people receiving antiretroviral therapy (ART) in a southern US city completed computerized measures at a community-based research site. Multiple mediation modeling showed that medical provider mistrust was associated with medication beliefs and ART adherence. Also, medication beliefs predicted adherence. The indirect effects of medical mistrust on adherence via medication beliefs was significant; the indirect effect was significant for medication concerns beliefs, but not medication necessity beliefs. Medication concerns beliefs therefore mediate the association between medical mistrust and ART adherence.

Race-based medical mistrust, medication beliefs and HIV treatment adherence: test of a mediation model in people living with HIV/AIDS

Race-based medical mistrust significantly predicts non-adherence to antiretroviral therapy (ART) in people living with HIV. The current study builds on previous research that shows beliefs about medication necessity (i.e., "My medicines protect me from becoming worse") and concerns (i.e., "Having to take my medicines worries me") mediate the association between race-based medical mistrust and medication adherence. Racial and ethnic minority men and women living with HIV and receiving ART (N = 178) in a southern US city completed computerized measures of demographic and health characteristics, telephone interviews of race-based medical mistrust and medication beliefs, and unannounced phone-based pill counts for ART adherence. Multiple mediation modeling showed that medical mistrust is related to medication necessity and concerns beliefs and ART adherence. Furthermore, medication necessity beliefs predicted ART adherence. The indirect effect of medical mistrust on adherence through medication necessity beliefs was also significant. Results confirm that medication necessity beliefs, although not concerns beliefs, mediate the association between medical mistrust and ART adherence. Medication necessity beliefs offer a viable target for interventions to improve ART adherence in the context of mistrust that patients may have for medical providers and health care systems.

A Multilevel Analysis of Neighborhood Socioeconomic Disadvantage and Transactional Sex with Casual Partners Among Young Men Who Have Sex with Men Living in Metro Detroit

The role of structural factors when evaluating the vulnerability of human immunodeficiency virus/sexually transmitted infection (HIV/STI) risks among young gay, bisexual, and other men who have sex with men is an important area of focus for HIV prevention. Using cross-sectional data from young men living in Metro Detroit (N = 319; aged 18-29 years; 50% black, 25% white, 15% Latino, 9% other race/ethnicity; 9% HIV-positive), we examined whether transactional sex with casual partners was associated with neighborhood-level socioeconomic disadvantage and individual-level factors (race/ethnicity and sexual identity, socioeconomic status, HIV/STI diagnoses, and substance use). Youth living in greater socioeconomic disadvantage reported more transactional sex (b = 0.11; SE = 0.04; p ≤ 0.01). This relationship was mitigated once individual-level correlates were entered into the model. Multilevel efforts to counteract socioeconomic deficits through community and individual level strategies may alleviate youth's exposure to transactional sex and reduce their vulnerability to HIV/STI risks.

Where You Live Matters: Structural Correlates of HIV Risk Behavior Among Young Men Who Have Sex with Men in Metro Detroit

Structural characteristics are linked to HIV/STI risks, yet few studies have examined the mechanisms through which structural characteristics influence the HIV/STI risk of young men who have sex with men (YMSM). Using data from a cross-sectional survey of YMSM (ages 18-29) living in Detroit Metro (N = 328; 9 % HIV-positive; 49 % Black, 27 % White, 15 % Latino, 9 % Other race), we used multilevel modeling to examine the association between community-level characteristics (e.g., socioeconomic disadvantage; distance to LGBT-affirming institutions) and YMSM's HIV testing behavior and likelihood of engaging in unprotected anal intercourse with serodiscordant partner(s). We accounted for individual-level factors (race/ethnicity, poverty, homelessness, alcohol and marijuana use) and contextual factors (community acceptance and stigma regarding same-sex sexuality). YMSM in neighborhoods with greater disadvantage and nearer to an AIDS Service Organization were more likely to have tested for HIV and less likely to report serodiscordant partners. Community acceptance was associated with having tested for HIV. Efforts to address YMSM's exposure to structural barriers in Detroit Metro are needed to inform HIV prevention strategies from a socioecological perspective.

Transactional Sex With Regular and Casual Partners Among Young Men Who Have Sex With Men in the Detroit Metro Area

Transactional sex refers to the commodification of the body in exchange for shelter, food, and other goods and needs. Transactional sex has been associated with negative health outcomes including HIV infection, psychological distress, and substance use and abuse. Compared with the body of research examining transactional sex among women, less is known about the prevalence and correlates of transactional sex among men. Using data from a cross-sectional survey of young men who have sex with men (ages 18-29) living in the Detroit Metro Area ( N = 357; 9% HIV infected; 49% Black, 26% White, 16% Latino, 9% Other race), multivariate logistic regression analyses examined the association between transactional sex with regular and casual partners and key psychosocial factors (e.g., race/ethnicity, education, poverty, relationship status, HIV status, prior sexually transmitted infections [STIs], mental health, substance use, and residential instability) previously identified in the transactional sex literature. Forty-four percent of the current sample reported engaging in transactional sex. Transactional sex was associated with age, employment status, relationship status, and anxiety symptoms. When stratified, transactional sex with a regular partner was associated with age, educational attainment, employment status, relationship status, anxiety, and alcohol use. Transactional sex with a casual partner was associated with homelessness, race/ethnicity, employment status, and hard drug use. The implications of these findings for HIV/STI prevention are discussed, including the notion that efforts to address HIV/STIs among young men who have sex with men may require interventions to consider experiences of transactional sex and the psychosocial contexts that may increase its likelihood.

Food insecurity and antiretroviral adherence among HIV positive adults who drink alcohol

Food insecurity is associated with HIV treatment non-adherence and poor health outcomes for people living with HIV/AIDS. Given the poor nutritional status common to people who drink alcohol, food insecurity may be particularly problematic for HIV positive individuals who drink alcohol. To examine food insecurity among HIV positive men and women who drink alcohol and its association with antiretroviral therapy (ART) adherence, health outcomes and health service utilization. Adults living with HIV (N = 183) in Atlanta, Georgia who reported alcohol use in the previous week and were receiving ART participated in a 12-month cohort. Participants were recruited from infectious disease clinics and social services to complete computerized interviews, monthly-unannounced pill counts to monitor ART adherence, and daily cell-phone delivered interactive-text assessments for alcohol use. Forty-three percent of participants experienced food insecurity during at least one month of the study period. Food insecurity was independently associated with suboptimal ART adherence and less suppressed HIV viral load over. Individuals who experienced food insecurity also had histories of more medical and psychiatric hospitalizations, and greater mental health problems. Food insecurity is prevalent among alcohol using people receiving ART and food insecurity is associated with treatment non-adherence, poor health outcomes, and increased medical and psychiatric hospitalizations.

Viral suppression and antiretroviral medication adherence among alcohol using HIV-positive adults

BACKGROUND

Substance use is a known predictor of poor adherence to antiretroviral therapies (ART) in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome. Less studied is the association between substance use and treatment outcomes, namely, suppression of HIV replication.

METHODS

Adults living with HIV (N = 183) who reported alcohol use in the previous week and receiving ART were observed over a 12-month period. Participants completed computer interviews, monthly unannounced pill counts to monitor ART adherence, and daily cell-phone delivered interactive-text assessments for alcohol use. HIV viral load was collected at baseline and 12-month follow-up from medical records. Analyses compared participants who had undetectable HIV viral loads at baseline and follow-up (sustained viral suppression) to those with unsustained viral suppression. Analyses also compared participants who were adherent to their medications (>85 % pills taken) over the year of observation to those who were nonadherent.

RESULTS

Fifty-two percent of participants had unsustained viral suppression; 47 % were ART nonadherent. Overall results failed to demonstrate alcohol use as a correlate of sustained viral suppression or treatment adherence. However, alcohol use was associated with nonadherence among participants who did not have sustained viral suppression; nonadherence in unsustained viral suppression patients was related to drinking on fewer days of assessment, missing medications when drinking, and drinking socially.

CONCLUSIONS

Poor HIV treatment outcomes and nonadherence were prevalent among adults treated for HIV infection who drink alcohol. Drinking in relation to missed medications and drinking in social settings are targets for interventions among alcohol drinkers at greatest risk for poor treatment outcomes.

Mild maternal stress disrupts associative learning and increases aggression in offspring

Maternal stress has been shown to affect behaviour of offspring in a wide range of animals, but this evidence has come from studies that exposed gestating mothers to acute or severe stressors, such as restraint or exposure to synthetic stress hormones. Here we show that exposure of mothers to even a mild stressor reduces associative learning and increases aggression in offspring. Female guppies were exposed to routine husbandry procedures that produced only a minimal, non-significant, elevation of the stress hormone cortisol. In contrast to controls, offspring from mothers that experienced this mild stress failed to learn to associate a colour cue and food reward, and showed a greater amount of inter-individual variation in behaviour compared with control offspring. This mild stress also resulted in offspring that were more aggressive towards their own mirror image than controls. While it is possible that these results could represent the transmission of beneficial maternal characteristics to offspring born into unpredictable environments, the potential for mild maternal stress to affect offspring performance also has important implications for research into the trans-generational effects of stress.

The effect of risk-taking behaviour in epidemic models

We study an epidemic model that incorporates risk-taking behaviour as a response to a perceived low prevalence of infection that follows from the administration of an effective treatment or vaccine. We assume that knowledge about the number of infected, recovered and vaccinated individuals has an effect in the contact rate between susceptible and infectious individuals. We show that, whenever optimism prevails in the risk behaviour response, the fate of an epidemic may change from disease clearance to disease persistence. Moreover, under certain conditions on the parameters, increasing the efficiency of vaccine and/or treatment has the unwanted effect of increasing the epidemic reproductive number, suggesting a wider range of diseases may become endemic due to risk-taking alone. These results indicate that the manner in which treatment/vaccine effectiveness is advertised can have an important influence on how the epidemic unfolds.

Continued Substance Use Among People Living With HIV-Hepatitis-C Co-Infection and Receiving Antiretroviral Therapy

BACKGROUND

Co-infection with human immunodeficiency virus (HIV) and Hepatitis-C virus (HCV) poses a significant threat to personal and public health. Substance use among co-infected persons leads to increased morbidity and mortality. The purpose of this study is to examine the continued substance use of people living with HIV-HCV co-infection and receiving antiretroviral therapy (ART).

METHODS

Individuals living with HIV infection in Atlanta, GA and currently receiving ART (N = 678) completed audio-computer-assisted self-interviews for demographic, health, and behavior characteristics; unannounced pill counts to assess ART adherence over one month; finger-stick blood specimens collected for HCV antibody testing and urine specimens for drug use screening; and obtained HIV viral load and CD4 cell counts from their medical provider. We performed cross-sectional analyses for behavioral and biological markers of health, health behaviors, and substance use.

RESULTS

Among participants, 131 (19%) were HIV-HCV co-infected; 53% were HIV-mono-infected, and 60% of HIV-HCV co-infected participants tested positive for use of at least one non-alcohol drug: tetrahydrocannabinol (THC) and cocaine were most prevalent. HIV-HCV co-infected individuals were older, with no other significant differences. Within the HIV-HCV co-infected participants, drug users (N = 87) did not differ from non-drug users (N = 53) in terms of ART adherence. However, drug users were significantly more likely to have uncontrolled HIV (17%) compared with those who did not test drug positive (4%).

CONCLUSIONS

Substance use is prevalent in persons with HIV-HCV co-infection and may interfere with ART. Research with a larger and more representative sample is needed to replicate and confirm these results.

Elevated urinary leukocyte esterase as a potential surrogate marker for HIV sexual transmission risks in men receiving antiretroviral therapy

Local genital tract inflammation stimulates leukocyte activity and causes HIV shedding, potentially increasing HIV sexual infectiousness. Although there are available clinical markers for genital tract inflammation, such as urinary leukocyte esterase, none have yet been examined in relation to HIV sexual risk behaviours. We sought to examine the association between urinary leukocyte esterase and sexual practices. Sexually active men living with HIV and receiving antiretroviral therapy (ART, N = 290) provided urine specimens and completed behavioural health assessments. HIV RNA tests and CD4 cell counts were abstracted from medical records. Urine specimens were analysed for leukocyte esterase using a standard point-of-care dipstick test. Thirty-one (10.6%) participants tested positive for leukocyte esterase. Logistic regression models did not indicate differences between men with elevated and un-elevated leukocyte activity on demographic, health, recent sexually transmitted infection symptoms and diagnoses or substance use. However, men with elevated leukocyte activity indicated significantly greater sexual behaviour in the previous three months, including more recent unprotected sexual intercourse. A simple over-the-counter urine test may serve as an indicator of sexual HIV infectiousness to inform further evaluation and treatment of genital tract inflammation, as well as condom use decisions during times of increased genital tract inflammation.

Collective efficacy and HIV prevention in South African townships

South African townships have high HIV prevalence and a strong need for collective action to change normative sexual risk behaviors. This study investigated the relationship between perceptions of individuals about collective efficacy in the community's ability to prevent HIV and their personal HIV risk behaviors. Men (n = 1,581) and women (n = 718) completed anonymous surveys within four Black African Townships in Cape Town, South Africa from June 2008 to December 2010. Measures included demographics, alcohol use, attitudinal and behavioral norms, sexual health communications, and sexual risk behaviors. In multivariate logistic regressions, men were more likely to endorse collective efficacy if they were married, drank less often in alcohol serving establishments, believed that fewer men approve of HIV risk behaviors, talk more with others about HIV/AIDS, and had more sex partners in the past month. Women were more likely to endorse collective efficacy if they drank alcohol less often, talked more with others about HIV/AIDS, had more sex partners in the past month, but reported fewer unprotected sex acts in the past month. Community level interventions that strengthen collective efficacy beliefs will have to consider both protective and risk behaviors associated with believing that the community is ready and capable of preventing HIV.

Abstract OT2-6-13: A randomized phase 2 study of the triplet combination of ridaforolimus (RIDA), dalotuzumab (DALO) and exemestane (EX) compared to the ridaforolimus, exemestane doublet in high proliferation, estrogen receptor positive (ER+) advanced breast cancer

Background: The clinical benefit of combination of mTOR inhibition and anti-hormonal therapy has been previously established and represents a new standard of care for patients with hormone receptor positive (HR+) advanced breast cancer (ABC). Preclinical evaluation of the mTOR pathway demonstrates that dual inhibition of IGFR and mTOR may be additive or synergistic and abrogates the feedback activation of AKT due to rapamycin analog mTOR inhibitors. A completed phase 1 study of the combination of the mTOR inhibitor, RIDA and the anti-IGFR antibody, DALO demonstrated preliminary signals of anti-tumor activity. This was further evaluated in a recently completed phase 2 study of RIDA-DALO compared to exemestane in ER+ ABC. Final safety and efficacy results from that phase 2 study will be reported at this meeting (see Baselga et al). Building upon the clinical synergies of mTOR and EX as well as the biologic relationship of the mTOR and IGFR pathways, a clinical study has been initiated to evaluate the triplet combination of RIDA-DALO-EX compared to RIDA-EX. Methods: This is a multicenter, international, randomized phase 2 study of the triplet combination of RIDA (10 mg by mouth daily for 5 out of every 7 days), DALO (10 mg/kg IV weekly), and EX (25 mg QD) compared to RIDA (30 mg by mouth daily for 5 out of every 7 days) and EX (25 mg QD) in high KI67 (≥15%) expressing ER+, ABC. Approximately 84 patients will be randomized 1:1 to either triplet or doublet therapy. Key eligibility criteria include: HR+ and HER-2 negative measurable ABC, prior therapy with a non-steroidal aromatase inhibitor, and KI67 labeling index ≥15%. The primary endpoint of the study is progression free survival (PFS). Key secondary endpoints include evaluation of percent (%) reduction from baseline in the sum of imaging measurements (target lesion diameters or volumes) at 16 weeks between the two arms, and overall response rates. The sample size is event driven with a target of 38 PFS events, which provides approximately 80% power, at 1-sided alpha of 0.1, to detect a HR of 0.5, corresponding to an approximate 100% improvement in median PFS, from 10.6 to 21.2 months. Safety parameters or adverse experiences of special interest include hyperglycemia, stomatitis, mucosal inflammation, pneumonitis and hearing loss. Accrual has been completed with results expected in May 2014.

Abstract P2-16-04: A phase 2 study of ridaforolimus (RIDA) and dalotuzumab (DALO) in estrogen receptor positive (ER+) breast cancer

Background: Preclinical studies indicate that the dual inhibition of IGFR and mTOR may be additive or synergistic and abrogates the feedback activation of AKT due to rapamycin analog mTOR inhibitors. A phase 1 study of the mTOR inhibitor RIDA and the anti-IGFR antibody DALO demonstrated that the combination was feasible and well-tolerated at doses that were nearly those used for the two single agents. The dose limiting toxicity was stomatitis, similar to RIDA monotherapy. Preliminary signals of anti-tumor activity, including partial responses and prolonged progression free survival (PFS), were observed in ER+ advanced breast cancer (ABC), especially in high proliferation tumors (Ki67 ≥15%). Methods: The trial was a multi-center, international randomized study with PFS as the primary endpoint. Key eligibility included ABC with prior treatment with a non-steroidal aromatase inhibitor. The original phase 2 study design was a two-part, adaptive design intended to first test the combination of RIDA (30 mg by mouth daily for 5 out of every 7 days), -DALO (10 mg/kg IV weekly) against a standard agent, exemestane in Part A. Patients were stratified into high and low proliferation strata based on baseline Ki67. Following a demonstration of PFS benefit of the combination in Part A, Part B was intended to show the PFS benefit of the combination over each single agents by comparing RIDA-DALO to RIDA and DALO. Results: The study was initiated in October 2011. Accrual was suspended after the first 66 patients were randomized due to a higher than expected rate of stomatitis in the RIDA-DALO arm. Preliminary data indicated an overall incidence of any grade stomatitis was 68% (22/33 pts), and of grade 3 stomatitis was 35% (11/33 pts). In an effort to identify a more tolerable regimen, the study was amended to eliminate Part B and to evaluate two sequential reduced dose RIDA-DALO cohorts in a non-randomized design: 20mg and 10mg for 5 out of every 7 days. The dose of DALO was unchanged. Preliminary safety results of overall and grade 3 stomatitis in the 20 mg were 81.5% (22/27 pts) and 37% (10/27 pts), respectively. Although the incidence of overall stomatitis in the 10 mg cohort remained high, 88% (22/25 pts), grade 3 stomatitis was dramatically reduced to 8% (2/25 pts). Conclusion: Preliminary evaluation of safety from this phase 2 study demonstrates that the previously recommended phase 2 dose of RIDA-DALO was not tolerable. However lower doses of RIDA (10 mg) in combination with DALO appeared to be tolerable with markedly reduced rates of grade 3 stomatitis. Final results of efficacy, safety and RNA profiling analysis from the two RIDA-DALO dose cohorts as well as from the randomized portion of the study will be available at the time of the meeting.

Randomized community-level HIV prevention intervention trial for men who drink in South African alcohol-serving venues

BACKGROUND

South African alcohol-serving establishments (i.e., shebeens) offer unique opportunities to reduce HIV risks among men who drink.

PURPOSE

To test an individual- and a social structural-level HIV prevention intervention for men who drink in shebeens.

METHODS

Twelve matched pairs of township neighbourhoods were randomized to receive either (i) an HIV prevention intervention (guided by Social Action Theory) to reduce sexual risk and increase risk reduction communication in social networks, or (ii) an attention-matched control intervention that focused on the prevention of relationship violence. At the individual level, the interventions delivered skills building workshops focused on sexual risk reduction. At the social structural level, the intervention aimed to increase conversations about safer sex among men in the shebeens, distributed small media and implemented community educational events. Individual-level outcomes were assessed by following the workshop cohorts for 1 year (N = 984), and community-level outcomes were examined through cross-sectional community surveys conducted for 1 year in the shebeens (N = 9,678).

RESULTS

Men in the HIV prevention workshops demonstrated greater condom use, more HIV prevention-oriented conversations and greater perceptions of safer sex norms than men in the comparison workshops. Changes at the community level demonstrated significant differences in condom use, although the pattern was not consistent over time.

CONCLUSIONS

Multi-level interventions that target men who drink in South African shebeens may help reduce risks for HIV and other sexually transmitted infections.

Intentional non-adherence to medications among HIV positive alcohol drinkers: prospective study of interactive toxicity beliefs

BACKGROUND

Antiretroviral therapy (ART) adherence is key to successful treatment of HIV infection and alcohol is a known barrier to adherence. Beyond intoxication, ART adherence is impacted by beliefs that mixing alcohol and medications is toxic.

PURPOSE

To examine prospective relationships of factors contributing to intentional medication non-adherence when drinking.

METHODS

People who both receive ART and drink alcohol (N = 178) were enrolled in a 12-month prospective cohort study that monitored beliefs about the hazards of mixing ART with alcohol (interactive toxicity beliefs), alcohol consumption using electronic daily diaries, ART adherence assessed by both unannounced pill counts and self-report, and chart-abstracted HIV viral load.

RESULTS

Participants who reported skipping or stopping their ART when drinking (N = 90, 51 %) demonstrated significantly poorer ART adherence, were less likely to be viral suppressed, and more likely to have CD4 counts under 200/cc(3). Day-level analyses showed that participants who endorsed interactive toxicity beliefs were significantly more likely to miss medications on drinking days.

CONCLUSIONS

Confirming earlier cross-sectional studies, the current findings from a prospective cohort show that a substantial number of people intentionally skip or stop their medications when drinking. Interventions are needed to correct alcohol-related interactive toxicity misinformation and promote adherence among alcohol drinkers.

Bringing it home: community survey of HIV risks to primary sex partners of men and women in alcohol-serving establishments in Cape Town, South Africa

Background

Concurrent sexual relationships facilitate the spread of HIV infection, and sex with non-primary partners may pose particularly high risks for HIV transmission to primary partners.

Objective

We examined the sexual and alcohol-related risks associated with sex partners outside of primary relationships among South African men and women in informal drinking establishments.

Methods

Men (n=4959) and women (n=2367) with primary sex partners residing in a Xhosa-speaking South African township completed anonymous surveys. Logistic regressions tested associations between having outside partners and risks for sexually transmitted infections (STI)/HIV.

Results

Forty-four percent of men and 26% women with primary sex partners reported also having outside sex partners in the previous month. Condom use with outside partners was inconsistent for men and women; only 19% of men and 12% of women used condoms consistently with outside sex partners. Multivariable regressions for men and women showed that having outside partners was significantly associated with having been diagnosed with an STI, consuming alcohol in greater frequency and quantity, alcohol use during sex, meeting sex partners in alcohol-serving venues, and higher rates of unprotected sex.

Conclusions

Having outside sex partners was associated with multiple risk factors for HIV infection among South African shebeen patrons. Social and structural interventions that encourage condom use are needed for men and women with outside partners who patronise alcohol-serving venues.

Assumed infectiousness, treatment adherence and sexual behaviours: applying the Swiss Statement on infectiousness to HIV-positive alcohol drinkers

OBJECTIVES

The success of antiretroviral therapy (ART) for treating HIV infection is now being turned towards HIV prevention. The Swiss Federal Commission for HIV/AIDS has declared that HIV-positive persons who are treated with ART, have an undetectable viral load, and are free of co-occurring sexually transmitted infections (STIs) should be considered noninfectious for sexual transmission of HIV. This study examined the implications of these assumptions in a sample of HIV-positive individuals who drink alcohol.

METHODS

People living with HIV/AIDS (n = 228) were recruited through community sampling. They completed confidential computerized interviews and underwent monthly unannounced pill counts for ART adherence. HIV viral loads were obtained from medical records.

RESULTS

One hundred and eighty-five HIV-positive drinkers were currently receiving ART and 43 were untreated. Among those receiving ART, one in three were not virally suppressed and one in five had recently been diagnosed with an STI. Adherence was generally suboptimal, including among those assumed to be less infectious. As many as one in four participants reported engaging in unprotected intercourse with an HIV-uninfected partner in the past 4 months. There were few associations between assumed infectiousness and sexual practices.

CONCLUSIONS

Less than half of people who drank alcohol and took ART met the Swiss criteria for noninfectiousness. Poor adherence and prevalent STI threaten the long-term potential of using ART for prevention. In the absence of behavioral interventions, the realities of substance use and other barriers call into question the use of ART as prevention among alcohol drinkers.

OT3-01-16: A Phase 2 Study of Ridaforolimus (RIDA) and Dalotuzumab (DALO) in Estrogen Receptor Positive (ER+) Breast Cancer

Background: Activation of the PI3K/AKT/mTOR pathway is common in breast cancer. Preclinical studies indicate that the dual inhibition of IGFR and mTOR may be additive or synergistic and abrogates the feedback activation of AKT due to rapamycin analog mTOR inhibitors. A phase 1 study of the mTOR inhibitor RIDA and the anti-IGFR antibody DALO demonstrated that the combination was feasible and well-tolerated at doses that were nearly those used for the two single agents and with dose limiting toxicity of stomatitis, similar to RIDA as monotherapy. A preliminary signal of anti-tumor activity, including partial responses and prolonged progression free survival, was observed in ER+ breast cancer, especially in high proliferation tumors. This observation is supported by data from tumor profiling and preclinical data suggesting that ER+ high proliferation breast cancer may be responsive to the RIDA-DALO combination. Methods: This is a two-part, adaptive design study intended to first test the combination of RIDA-DALO against a standard agent, exemestane, for ER+ positive breast cancer that has progressed after aromatase inhibitors. The trial is a multi-center, international, randomized study with PFS as the primary endpoint. Patients (pts) are stratified into high and low proliferation strata based on baseline Ki67, and the low proliferation stratum is capped to ensure adequate enrollment of high proliferation pts. If Part A shows a PFS benefit for RIDA-DALO, Part B is intended to show the PFS benefit of the combination over the single agents by comparing RIDA-DALO to RIDA and DALO. Part B will be further adapted based on whether the PFS benefit in Part A is observed in all-comers or the high proliferation subset. Tumor tissue is collected for molecular profiling and analysis of intrinsic subtype, with an efficacy analysis based on classification of tumors using the genomic grade index (GGI) as an exploratory objective. This trial design is intended to establish proof of concept that RIDA-DALO can prolong PFS in ER+ breast cancer in all-comers or a high proliferation subset by Ki67, while efficiently addressing the development of two investigational agents in combination and leading to a two-arm Phase 3 design.

On-line bariatric surgery information session as effective as in-person information session

BACKGROUND

All patients at our academic medical center complete a mandatory bariatric surgery information session before scheduling their first clinic visit. The patients could attend an in-person information session or view a prerecorded information session through our Web site. The study aimed to compare the information retention after both delivery methods using an institutional review board-approved test in an academic medical center in the United States.

METHODS

From February 2010 through March 2011, 338 tests were voluntarily completed by new preoperative bariatric patients at their clinic visit. The patients provided basic demographic information, co-morbid medical conditions, and identified which bariatric procedures they were interested in. The test assessed the retention of information delivered during the information session, including knowledge of the risks and benefits of bariatric surgery, the surgical options available at our center, and the steps commonly required for insurance approval. The patients and surgeons were kept unaware of the results.

RESULTS

Of the patients, 54% attended the on-line information session; 80% of these participants were women, and their mean body mass index was 48.09 kg/m(2). The remaining 46% attended the in-person information session, and 83% of these participants were women and their mean body mass index was 49.08 kg/m(2). The average test score was 85.69% for the on-line group and 80.32% for the in-person group. The difference in test scores for the on-line and in-person groups was statistically significant (P = .003).

CONCLUSION

Internet-based training is rapidly becoming a key educational tool. Our results suggest that on-line training has the potential to be as effective as traditional in-person training in educating patients about bariatric surgery. Bariatric surgery centers might consider incorporating on-line training into their educational programs as a convenient and potentially effective way to educate patients.

Randomized clinical trial of brief risk reduction counseling for sexually transmitted infection clinic patients in Cape Town, South Africa

OBJECTIVES

We examined the effects of a brief counseling intervention designed to reduce HIV risk behaviors and sexually transmitted infections (STIs) among patients receiving STI services in Cape Town, South Africa.

METHODS

After randomization to either a 60-minute risk reduction counseling session or a 20-minute HIV-STI educational session, patients completed computerized sexual behavior assessments. More than 85% of the participants were retained at the 12-month follow-up.

RESULTS

There were 24% fewer incident STIs and significant reductions in unprotected vaginal and anal intercourse among participants who received risk reduction counseling relative to members of the control condition. Moderator analyses showed shorter lived outcomes for heavy alcohol drinkers than for lighter drinkers. The results were not moderated by gender.

CONCLUSIONS

Brief single-session HIV prevention counseling delivered to STI clinic patients has the potential to reduce HIV infections. Counseling should be enhanced for heavier drinkers, and sustained outcomes will require relapse prevention techniques. Disseminating effective, brief, and feasible behavioral interventions to those at highest risk for HIV infection should remain a public health priority.

Brief behavioral self-regulation counseling for HIV treatment adherence delivered by cell phone: an initial test of concept trial

Affordable and effective antiretroviral therapy (ART) adherence interventions are needed for many patients to promote positive treatment outcomes and prevent viral resistance. We conducted a two-arm randomized trial (n = 40 men and women receiving and less than 95% adherent to ART) to test a single office session followed by four biweekly cell phone counseling sessions that were grounded in behavioral self-management model of medication adherence using data from phone-based unannounced pill counts to provide feedback-guided adherence strategies. The control condition received usual care and matched office and cell phone/pill count contacts. Participants were baseline assessed and followed with biweekly unannounced pill counts and 4-month from baseline computerized interviews (39/40 retained). Results showed that the self-regulation counseling delivered by cell phone demonstrated significant improvements in adherence compared to the control condition; adherence improved from 87% of pills taken at baseline to 94% adherence 4 months after baseline, p < 0.01. The observed effect sizes ranged from moderate (d = 0.45) to large (d = 0.80). Gains in adherence were paralleled with increased self-efficacy (p < 0.05) and use of behavioral strategies for ART adherence (p < 0.05). We conclude that the outcomes from this test of concept trial warrant further research on cell phone-delivered self-regulation counseling in a larger and more rigorous trial.

Monthly unannounced pill counts for monitoring HIV treatment adherence: tests for self-monitoring and reactivity effects

BACKGROUND

Unannounced home-based pill counts conducted in person or on the telephone are reliable and valid for monitoring medication adherence. However, expecting to have one's pills counted, organizing medications for pill counts, and increased attention from the person conducting the pill counts may have reactive effects and inadvertently improve adherence. The current study determined whether monthly unannounced pill counts conducted by telephone influence adherence over time.

METHODS

Two prospective cohorts, one drawn from a social support condition in a behavioral intervention trial (n=186) and the other an observational study (n=187), were followed for 12 months and 8 months, respectively. Medication adherence was monitored using monthly unannounced pill counts conducted by telephone. In addition, blood plasma viral load was collected at the final pill count for the observational cohort.

RESULTS

Analyses did not indicate increases in medication adherence over time for antiretroviral or psychiatric medications among men, women, people with detectable and undetectable viral loads, and various medication regimens.

CONCLUSIONS

Unannounced pill counts conducted by telephone do not demonstrate reactivity effects and remain a viable, unobtrusive, objective method of monitoring medication adherence.

HIV super-infection beliefs and sexual practices of people living with HIV/AIDS

BACKGROUND

People living with HIV can be reinfected with a new viral strain resulting in potential treatment-resistant recombinant virus known as HIV super-infection. Individual's beliefs about the risks for HIV super-infection may have significant effects on the sexual behaviours of people living with HIV/AIDS. HIV super-infection beliefs and sexual behaviours among people living with HIV/AIDS were examined in the present study.

METHODS

Three hundred and twenty men, 137 women, and 33 transgender persons completed confidential surveys in a community research setting.

RESULTS

A majority of participants were aware of HIV super-infection and most believed it was harmful to their health. Hierarchical multiple regressions predicting protected anal/vaginal intercourse with same HIV status (seroconcordant) partners showed that older age and less alcohol use were associated with greater protected sex. In addition, HIV super-infection beliefs predicted protected sexual behaviour over and above participant age and alcohol use.

CONCLUSIONS

Beliefs about HIV super-infection exert significant influence on sexual behaviours of people living with HIV/AIDS and should be targeted in HIV prevention messages for HIV infected persons.

Integrated behavioral intervention to improve HIV/AIDS treatment adherence and reduce HIV transmission

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.

"There is no proof that HIV causes AIDS": AIDS denialism beliefs among people living with HIV/AIDS

AIDS denialists offer false hope to people living with HIV/AIDS by claiming that HIV is harmless and that AIDS can be cured with natural remedies. The current study examined the prevalence of AIDS denialism beliefs and their association to health-related outcomes among people living with HIV/AIDS. Confidential surveys and unannounced pill counts were collected from a convenience sample of 266 men and 77 women living with HIV/AIDS that was predominantly middle-aged and African American. One in five participants stated that there is no proof that HIV causes AIDS and that HIV treatments do more harm than good. AIDS denialism beliefs were more often endorsed by people who more frequently used the internet after controlling for confounds. Believing that there is a debate among scientists about whether HIV causes AIDS was related to refusing HIV treatments and poorer health outcomes. AIDS denialism beliefs may be common among people living with HIV/AIDS and such beliefs are associated with poor health outcomes.
