    Abstract In 2011, All Children's Hospital (ACH) joined the Johns Hopkins Health System (JHHS) and in so doing became a member of Johns Hopkins Medicine (JHM). The value proposition for the joining of ACH and JHHS/JHM was to transform ACH into an academic pediatric health system. This case study of the transformation provides evidence for the usefulness of a precision medicine framework to organize investments in programs and practices that further the tripartite mission of academic medical centers and may increase the value of the care they deliver.

    Abstract A large body of research has identified peer exposure as a key factor driving adolescent substance use. However, findings on the role of sex partners are less robust and mixed. This study aims to fill this gap by examining the independent contribution of close friends' and sex partners' alcohol and marijuana use on adolescents' use of these substances. A secondary data analysis of social network data collected in 2000-2002 from a household sample of African American youth (14-19 years old) in the Bayview and Hunter's Point neighborhoods of San Francisco was conducted. Index participants and their nominated close friends and romantic sex partners (N = 104 triads) self-reported recent alcohol and marijuana use (defined as any use in the past 3 months). Generalized estimated equations were used to estimate the independent association between adolescent's recent substance use and their friend's and sex partner's use. Adolescents with a marijuana-using romantic sex partner had a nearly six-fold higher odds of using marijuana compared to adolescents with a non-using partner, controlling for close friend's marijuana use and other confounders [OR:5.69, 95%CI: 1.94, 16.7]; no association with close friend's marijuana use was found. A similar pattern was observed for alcohol use. Adolescents with an alcohol-using romantic sex partner had increased odds of using alcohol compared to adolescents with a non-using partner, controlling for close friend's alcohol use and other confounders [OR:2.40, 95%CI: 1.02, 5.63]; no association with close friend's alcohol use was found. Romantic sex partners may play a unique and significant role in adolescent substance use. Peer-focused interventions may be more effective if they consider romantic sex partners. Future research should consider the role of romantic sex partners in changing social context related to substance use from adolescence to young adulthood.

    Abstract Adolescents and young adults (AYA) 13-24 years old make up a disproportionate 21% of new HIV diagnoses. Unfortunately, they are less likely to treat HIV effectively, with only 30% achieving viral suppression, limiting efforts to interrupt HIV transmission. Previous work with mindfulness-based stress reduction (MBSR) has shown promise for improving treatment in AYA living with HIV (AYALH). This randomized controlled trial compared MBSR with general health education (HT). Seventy-four 13-24-year-old AYALH conducted baseline data collection and were randomized to nine sessions of MBSR or HT. Data were collected at baseline, post-program (3 months), 6 and 12 months on mindfulness and HIV management [medication adherence (MA), HIV viral load (HIV VL), and CD4]. Longitudinal analyses were conducted. The MBSR arm reported higher mindfulness at baseline. Participants were average 20.5 years old, 92% non-Hispanic Black, 51% male, 46% female, and 3% transgender. Post-program, MBSR participants had greater increases than HT in MA (

    Abstract Purpose: To examine how interpersonal factors are associated with family, peer, and partner social support among urban female adolescents in sexual relationships.
    Design: Secondary data analysis of cross-sectional data.
    Setting: Two urban health clinics and community sites in Baltimore, Maryland.
    Participants: One hundred sixteen female adolescents (ages 16-19) with 131 heterosexual relationships from the Perceived Risk of Sexually Transmitted Diseases cohort.
    Measures: Interpersonal factors included parental monitoring, friend-partner connectedness, and feelings of intimacy for partner. Social support was measured using the Multidimensional Scale of Perceived Social Support with family, peer, and partner subdomains.
    Analysis: Multivariable linear regression models using baseline data and accounting for clustering of partners.
    Results: Adolescents perceived high levels of family, peer, and partner support, with the greatest coming from partners (range: 1-5; family mean: 4.0 [95% confidence interval, CI: 3.83-4.18]; peer mean: 4.2 [95% CI: 4.05-4.33]; partner mean: 4.5 [95% CI: 4.36-4.60]). Parental monitoring and friend-partner connectedness were significantly associated with greater family (
    Conclusion: Feeling connected to one's social network and having a connected network is an important contribution to social support for urban female adolescents in sexual relationships. Future research targeting interpersonal factors is warranted, as it may result in increased social support and promote positive sexual health behaviors in an urban female adolescent population.

    Abstract Purpose: Trust is an essential component of romantic relationships. It is not understood how youth respond to a relationship stressor, which may impact trust, such as perceiving to be at risk for a sexually transmitted infection or their partner has other sex partners. We used a system science approach to examine feedback between trust and prorelationship behaviors within adolescent relationships.
    Methods: A prospective cohort of clinic-recruited young women (N = 122), aged 16-19 years, completed daily questionnaires on partner-specific feelings and risk perceptions for 18 months. Relationship stressor defined as either perceiving the risk of sexually transmitted infection from a partner or partner had other sex partners. Prorelationship behaviors were more time spent with partner, sex with partner, and/or gift from partner. Time-lagged generalized estimating equation models were used to examine whether a relationship stressor is associated with a decrease in trust and whether prorelationship behaviors changed following the stressor.
    Results: Experiencing a stressor was associated with threefold increased odds of having a decrease in trust in the same week (odds ratio [OR] = 3.30, 95% confidence interval [CI]: 2.30-4.72). Trust increased significantly the week following the stressor (OR = 2.09, 95% CI: 1.54-2.85). An increase in trust relative to the week of the stressor was associated with a 65% increase in prorelationship behavior in the week following the stressor (OR = 1.65, 95% CI: 1.20-2.26).
    Conclusions: Data uniquely show that trust is impacted following a relationship stressor and that youth increase prorelationship behaviors following a drop in trust. The findings suggest that adolescents prioritize maintaining trust, which may impact engagement in protective health behaviors.

    Abstract HIV disproportionately impacts young African American men who have sex with men (MSM). In this study, we sought to understand how previous relationship experiences and expectations for romantic relationships influence condom use among young African American MSM. Twenty African American MSM age 16 to 24 years completed a semi-structured interview and questionnaire on sexual experiences, romantic relationships, and sexual behavior. We identified three major themes characterizing romantic male-male relationships: (1) partner selection, (2) relationship ideals and expectations, and (3) relationship rules for condom use. Our findings indicate that young African American MSM rely on previous relationship experiences and desires for romantic relationships to determine condom use in subsequent relationships. Participants revealed that their previous relationship experiences and desires are often in conflict with their descriptions of their ideal romantic relationships, and subsequently influences their condom use. Our findings fill a gap in the literature describing male-male romantic relationships and condom use among young African American MSM.

    Abstract Youth living with HIV have sub-optimal rates of adherence to antiretroviral therapy (ART). Mindfulness instruction interventions have shown promise for improving medication adherence, but the effects and mechanisms of these interventions are still being explored among people living with HIV, including youth. In the context of a randomized controlled trial of the efficacy of a Mindfulness-Based Stress Reduction (MBSR) program on ART adherence and viral suppression among youth living with HIV, we conducted 44 iterative, semi-structured, in-depth interviews with 20 study participants (13-24 years) recruited from clinics at two academic centers in Baltimore, Maryland. Interviews explored the social context and psychosocial dynamics of ART adherence in the context of the MBSR intervention, compared with those in a control arm. We employed thematic content analysis to systematically code and synthesize textual interview data. Participants' challenges with ART adherence were often situated within an ongoing process of working to manage HIV as a stigmatized, chronic condition in addition to other intersecting social stigmas, inequalities, and stressors. Participation in the MBSR program and related group support allowed participants to non-judgmentally observe and accept difficult thoughts, feelings, and experiences associated with living with HIV and taking ART, which facilitated greater reported adherence. Mindfulness training may stimulate new perspectives and understanding, including greater self- and illness-acceptance among youth living with HIV, leading to improved HIV outcomes.
