RESUMO

The substance use, violence, and AIDS (SAVA) syndemic framework is used to study risk for HIV/AIDS. As a secondary analysis from a large HIV/AIDS prevention study, we categorized participants into having from zero to three SAVA conditions based on the presence or absence of self-reported substance use in the past 4 months, history of lifetime sexual abuse, and intimate partner violence. We used Poisson regression models to examine the association between the number of SAVA conditions and sexual risk behavior. Among all participants (n = 195, median age, 20), 37.9%, 19.5%, and 6.7% reported occurrence of one, two, and all three SAVA conditions, respectively. We found that more than one SAVA condition experienced by women was significantly associated with having more than one sex partner (adjusted prevalence ratio [aPR] = 1.88; 95% confidence interval [CI] = 1.28, 2.76) and with substance use before sex (aPR = 1.61 95% CI = 1.06, 2.45).

RESUMO

BACKGROUND: The COVID-19 pandemic illuminated the benefits of telemedicine. Self-collected specimens are a promising alternative to clinician-collected specimens when in-person testing is not feasible. In this study, we assessed the adequacy of self-collected pharyngeal and rectal specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae among individuals undergoing chlamydia and gonorrhea screening. METHODS: We used data from a large cohort study that included male and female adolescents between the ages of 12-24 years. We considered self-collected specimens adequate for clinical use if the human synthase gene (a control target of the assay) was detected in the specimen. RESULTS: In total, 2,458 specimens were included in the analysis. The human synthase gene was detected in 99.2% (2,439/2,458) of all self-collected specimens, 99.5% (1,108/1,114) of the pharyngeal specimens, and 99.0% (1,331/1,344) of the rectal specimens. CONCLUSION: Self-collected pharyngeal and rectal specimens demonstrated a very high proportion of human gene presence, suggesting that self-collection was accurate. A limitation of this study is that the sample adequacy control detects the presence or absence of the human hydroxymethylbilane synthase gene, but it does not indicate the specific anatomic origin of the human hydroxymethylbilane synthase gene. Self-collected specimens may be an appropriate alternative to clinician-collected specimens.

RESUMO

In response to the COVID-19 pandemic, our team adjusted study procedures to support research staff wellbeing. ATN CARES is a community-based, adolescent-focused HIV research program. Our participants and frontline staff alike are predominantly Black or Latinx sexual and gender minorities. Senior researchers and staff collaborated to refine our procedures, anticipating stay-at-home orders in March 2020. Transition to virtual space appeared seamless; however, we did not foresee that staff would have the additional role of providing COVID-19-related informational and emotional support to participants. This and the added strain of working remotely were increasing staff stress and in general negatively affecting staff wellbeing. Leveraging staff interests and skills, staff and senior researchers developed purposeful ways to stay connected and alleviate these strains, including exercise sessions; professional development workshops; motivational messages; and games. These proved beneficial and serve as a reminder that wellbeing of staff-our frontline heroes-is vital to a successful research project.

RESUMO

Machine learning creates new opportunities to design digital health interventions for youth at risk for acquiring HIV (YARH), capitalizing on YARH's health information seeking on the internet. To date, researchers have focused on descriptive analyses that associate individual factors with health-seeking behaviors, without estimating of the strength of these predictive models. We developed predictive models by applying machine learning methods (i.e., elastic net and lasso regression models) to YARH's self-reports of internet use. The YARH were aged 14-24 years old (N = 1287) from Los Angeles and New Orleans. Models were fit to three binary indicators of YARH's lifetime internet searches for general health, sexual and reproductive health (SRH), and social service information. YARH responses regarding internet health information seeking were fed into machine learning models with potential predictor variables based on findings from previous research, including sociodemographic characteristics, sexual and gender minority identity, healthcare access and engagement, sexual behavior, substance use, and mental health. About half of the YARH reported seeking general health and SRH information and 26% sought social service information. Areas under the ROC curve (≥ .75) indicated strong predictive models and results were consistent with the existing literature. For example, higher education and sexual minority identification was associated with seeking general health, SRH, and social service information. New findings also emerged. Cisgender identity versus transgender and non-binary identities was associated with lower odds of general health, SRH, and social service information seeking. Experiencing intimate partner violence was associated with higher odds of seeking general health, SRH, and social service information. Findings demonstrate the ability to develop predictive models to inform targeted health information dissemination strategies but underscore the need to better understand health disparities that can be operationalized as predictors in machine learning algorithms.

RESUMO

BACKGROUND: Public health organizations have inconsistent recommendations for screening adolescents and young adults for Chlamydia trachomatis and Neisseria gonorrhoeae infections. Guidelines suggest different combinations of anorectal, pharyngeal, and urogenital testing based on age, sex, and sexual activity. Further evaluation of how identity and behaviors impact the anatomic distribution of C. trachomatis and N. gonorrhoeae infection is needed to optimize future screening practices. METHODS: We assessed the positivity of C. trachomatis and N. gonorrhoeae infections at different anatomic sites in a cohort of at-risk sexually active adolescents and young adults aged 12-24 years in New Orleans, Louisiana and Los Angeles, California. Participants were tested for C. trachomatis and N. gonorrhoeae at 3 sites (anorectum, pharynx, and urethral/cervix) every 4 months using self-collected swabs. We stratified anatomic distributions of infection into 4 gender and sexual behavior categories: (1) cisgender men who have sex with men and transgender women (MSMTW); (2) cisgender heterosexual males; (3) cisgender heterosexual females; and (4) gender minorities assigned female at birth. RESULTS: While three-site testing detected all infections, two-site (anorectum and urethra/cervix) testing identified 92%-100% of C. trachomatis or N. gonorrhoeae infections in participants assigned female at birth and cisgender heterosexual males. For MSMTW, two-site anorectal and pharyngeal testing vs single-site anorectal testing increased the proportion of individuals with either infection from 74% to 93%. CONCLUSIONS: Sexual behavior and gender identity may influence detection of C. trachomatis and N. gonorrhoeae infections at specific anatomic testing sites. Testing guidelines should incorporate sexual behavior and gender identity. CLINICAL TRIALS REGISTRATION: NCT03134833.

RESUMO

BACKGROUND: Gay, bisexual, transgender, and homeless youth are at risk of sexually transmitted infections. As part of an adolescent human immunodeficiency virus prevention study, we provided same-day Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing and treatment. We aimed to evaluate the feasibility and effectiveness of same-day CT and NG treatment on the proportion of participants receiving timely treatment. METHODS: We recruited adolescents with high sexual risk behaviors aged 12 to 24 years from homeless shelters, lesbian, gay, bisexual, and transgender organizations, and community health centers in Los Angeles, California, and New Orleans, Louisiana from May 2017 to June 2019. Initially, participants were offered point-of-care pharyngeal, rectal, and urethral/vaginal CT and NG testing and referral to another clinic for treatment. After March 2018 in Los Angeles and November 2018 in New Orleans, we provided same-day treatment (and partner treatment packs) for study participants. We measured the proportion of participants who received same-day treatment and the median time to treatment. We collected frequency of partner treatment and any reported adverse treatment-related events. RESULTS: The proportion of participants receiving same-day CT and NG treatment increased from 3.6% (5/140) to 21.1% (20/95; Δ17.5%; 95% confidence interval, 9.2%-26.9%) after implementation of same-day testing and treatment. The median time to treatment decreased from 18.5 to 3 days. Overall, 36 participants took a total of 48 partner treatment packs. There were no reported treatment-related adverse events. CONCLUSIONS: Providing sexually transmitted infection treatment to adolescents at the same visit as testing is feasible and safe, and can increase the proportion of individuals receiving timely treatment.
