Objective: To review the current state of knowledge on the prevention of sexual transmission of HIV in adolescents and to highlight the existing gaps and priority areas for future research.
Background: A disproportionate burden of HIV infections falls on adolescents, a developmental stage marked by unique neural, biological, and social transition. Successful interventions are critical to prevent the spread of HIV in this vulnerable population. Methods: We summarized the current state of research on HIV prevention in adolescents by providing examples of successful interventions and best practices, and highlighting current research gaps.
Results: Adolescent interventions fall into 3 main categories: biomedical, behavioral, and structural. The majority of current research has focused on individual behavior change, whereas promising biomedical and structural interventions have been largely understudied in adolescents. Combination prevention interventions may be particularly valuable to this group.
Conclusions: Adolescents have unique needs with respect to HIV prevention, and, thus, interventions should be designed to most effectively reach out to this population with information and services that will be relevant to them.
The United States now has the highest incarceration rate in the world. The majority of prison and jail inmates come from predominantly nonwhite and medically underserved communities. Although incarceration has adverse effects on both individual and community health, prisons and jails have also been used successfully as venues to provide health services to people with HIV who frequently lack stable health care. We review demographic trends shaping the difficulties in providing care to incarcerated people with HIV and recommend the Centers for AIDS Research Collaboration on HIV in Corrections as a model of interdisciplinary collaboration in addressing those difficulties.
Background: Gay, bisexual, and other men who have sex with men account for a disproportionate burden of HIV incidence in the United States, with one-Third to two-Thirds of these new HIV infections occurring within main partnerships. Early initiation and adherence to highly active antiretroviral treatment is a key factor in treating and preventing the transmission of HIV; however, the average rate of adherence in the United States is low. Social support has been examined as a source of improving health for people experiencing a variety of chronic health conditions. This study aims to understand perceptions of how dyadic HIV care could influence partner-specific support for same-sex male couples with a goal of improving adherence.
Methods: Data were collected from 5 focus group (n = 35) discussions with gay and bisexual men in same-sex male relationships in Atlanta, GA. Participants discussed perceptions of how dyadic HIV care would impact partner support among serodiscordant and seroconcordant HIV-positive same-sex male couples. Verbatim transcripts were segmented thematically and systematically analyzed to examine patterns.
Results: Participants described how dyadic HIV care can facilitate emotional, informational, and instrumental support at various stages across the continuum of care, depending on partner dynamics. Participants stated that dyadic HIV care can provide an additional "sense of togetherness" and "solidarity" that helps to "alleviate stress."
Conclusions: Results suggest that dyadic approaches for HIV care across the continuum may be useful in promoting partner support and improving adherence. Future research should further examine dyadic interventions for HIV treatment among same-sex male couples.

Intermittent dosing of pre-exposure prophylaxis (iPrEP) has potential to decrease costs, improve adherence, and minimize toxicity. Practical event-based dosing of iPrEP requires men who have sex with men (MSM) to be sexually active on fewer than 3 days each week and plan for sexual activity. MSM who may be most suitable for event-based dosing were older, more educated, more frequently used sexual networking websites, and more often reported that their last sexual encounter was not with a committed partner. A substantial proportion of these MSM endorse high-risk sexual activity, and event-based iPrEP may best target this population.

African Americans and Hispanics in the United States have much higher rates of HIV than non-minorities. There is now strong evidence that a range of behavioral interventions are efficacious in reducing sexual risk behavior in these populations. Although a handful of these programs are just beginning to be disseminated widely, we still have not implemented effective programs to a level that would reduce the population incidence of HIV for minorities. We proposed that innovative approaches involving computational technologies be explored for their use in both developing new interventions and in supporting wide-scale implementation of effective behavioral interventions. Mobile technologies have a place in both of these activities. First, mobile technologies can be used in sensing contexts and interacting to the unique preferences and needs of individuals at times where intervention to reduce risk would be most impactful. Second, mobile technologies can be used to improve the delivery of interventions by facilitators and their agencies. Systems science methods including social network analysis, agent-based models, computational linguistics, intelligent data analysis, and systems and software engineering all have strategic roles that can bring about advances in HIV prevention in minority communities. Using an existing mobile technology for depression and 3 effective HIV prevention programs, we illustrated how 8 areas in the intervention/implementation process can use innovative computational approaches to advance intervention adoption, fidelity, and sustainability.
Background: Peripartum immunologic changes may affect latent tuberculosis infection (LTBI) diagnostic performance among HIVinfected women. Methods: HIV-infected women were serially tested with tuberculin skin test (TST) and interferon gamma release assay [QuantiFERON TB Gold In-tube (QFT)] in pregnancy and 6 weeks postpartum in Kenya. Prevalence, sensitivity and agreement, and correlates of QFT/TST positivity were assessed. Quantitative QFT mitogen and Mycobacterium tuberculosis antigen (Mtb-Ag) responses were compared by peripartum stage. Incidence of test conversion at 6 weeks postpartum was evaluated in baseline TST2/QFT2 women. Results: Among 100 HIV-infected women, median age was 26 years, median CD4 was 555 cells per cubic millimeter, and 88% were on antiretrovirals. More women were QFT+ than TST+ in both pregnancy (35.4% vs. 13.5%, P = 0.001) and postpartum (29.6% vs. 14.8%, P , 0.001). Among 18 consistently QFT+ women, 8 (44%) converted from TST2 to TST+, with improved test agreement postpartum (56.9%, k = 0.20 to 82.4%, k = 0.60). Three initially QFT2/TST2 women had test conversion (TST+ and/or QFT+), suggesting new infection (incidence 13.4/100 person-years). Mean QFT mitogen (4.46 vs. 7.64 IU/mL, P , 0.001) and Mtb-Ag (1.03 vs. 1.54 IU/mL, P = 0.03) responses were lower among all women retested in pregnancy vs. postpartum, and specifically among persistently QFT+ women (Mtb-Ag: 3.46 vs. 4.48 IU/mL, P = 0.007). QFT indeterminate rate was higher in pregnancy (16%) compared with postpartum (0%) because of lower mitogen response. Conclusions: QFT identified .2-fold more women with LTBI compared with TST in pregnancy and postpartum. Lower QFT Mtb-Ag and mitogen responses in pregnancy compared with postpartum suggest that pregnancy-associated immunologic changes may influence LTBI test performance.

Initiation of antiretroviral therapy during acute HIV-1 infection may prevent persistent immune activation. We analyzed longitudinal CD38+HLA-DR+ CD8+ T-cell percentages in 31 acutely infected individuals who started early (median 43 days since infection) and successful antiretroviral therapy, and maintained viral suppression through 96 weeks. Pretherapy a median of 72.6% CD8+ T cells were CD38+HLA-DR+, and although this decreased to 15.6% by 96 weeks, it remained substantially higher than seronegative controls (median 8.9%, P = 0.008). Shorter time to suppression predicted lower activation at 96 weeks. These results support the hypothesis that very early events in HIV-1 pathogenesis may result in prolonged immune dysfunction.

BACKGROUND:: The number of HIV-infected women giving birth in the United States is increasing. Research on pregnancy planning in HIV-infected women is limited.
METHODS:: Between January 1 and December 30, 2012, pregnant women with a known HIV diagnosis before conception at 12 US urban medical centers completed a survey including the London Measure of Unplanned Pregnancy (LMUP) scale. We assessed predictors of LMUP category (unplanned/ambivalent versus planned pregnancy) using bivariate and multivariable analyses.
RESULTS:: Overall, 172 women met inclusion criteria and completed a survey. Based on self-report using the LMUP scale, 23% women had an unplanned pregnancy, 58% were ambivalent, and 19% reported a planned pregnancy. Women were at lower risk for an unplanned or ambivalent pregnancy if they had previously given birth since their HIV diagnosis [adjusted relative risk (aRR) = 0.67, 95% confidence interval (CI): 0.47 to 0.94, P = 0.02], had seen a medical provider in the year before the index pregnancy (aRR = 0.60, 95% CI: 0.46 to 0.77, P < 0.01), or had a patient-initiated discussion of pregnancy intentions in the year before the index pregnancy (aRR = 0.63, 95% CI: 0.46 to 0.77, P < 0.01). Unplanned or ambivalent pregnancy was not associated with age, race/ethnicity, or educational level.
CONCLUSIONS:: In this multisite US cohort, patient-initiated pregnancy counseling and being engaged in medical care before pregnancy were associated with a decreased probability of unplanned or ambivalent pregnancy. Interventions that promote healthcare engagement among HIV-infected women and integrate contraception and preconception counseling into routine HIV care may decrease the risk of unplanned pregnancy among HIV-infected women in the United States.
