RESUMO
BACKGROUND: While there is no cure for HIV, adherence to antiretroviral therapy can extend the lifespan and improve the quality of life of people with HIV. Despite the global reduction of HIV infection rates in recent years, New York City and La Romana, Dominican Republic, continue to report high infection rates among Latino populations. Many people with HIV remain virally unsuppressed in these geographic hotspots, suggesting a need for additional interventions to overcome medication adherence barriers. Tailored and culturally appropriate mobile health (mHealth) technology can be an engaging way to improve adherence. The primary objective of this trial is to test the effectiveness of an mHealth tool to improve HIV medication adherence among Spanish-speaking people living in New York City and the Dominican Republic. METHODS: The WiseApp study is a two-arm randomized controlled trial among 248 people with HIV across the New York and Dominican Republic sites over the course of 12 months. Participants are randomly assigned to either receive a CleverCap pill bottle that is linked to the WiseApp (intervention) or standard of care (control). All participants complete surveys at baseline, 3-month, 6-month, and 12-month follow-up visits and the study team obtains HIV-1 viral load and CD4 count results through blood draw at each study timepoint. DISCUSSION: The use of mHealth technologies to improve medication adherence among people with HIV has been implemented in recent years. Although some studies have found improvement in adherence to antiretroviral therapy in the short term, there is limited information about how these interventions improve adherence among Spanish-speaking populations. Disproportionate rates of HIV infection among Latinos in New York City suggest an existing inequitable approach in reaching and treating this population. Due to a lack of mHealth studies with Latino populations, and apps tailored to Spanish-speakers, the WiseApp study will not only demonstrate the effectiveness of this particular mHealth app but will also contribute to the mHealth research community as a whole. TRIAL REGISTRATION: This trial was registered with Clinicaltrials.gov (NCT05398185) on 5/31/2022.

Hair and nail cortisol is increasingly studied as a physiologic proxy for chronic stress response. Glucocorticoid use is an expected confounder for cortisol measurement, yet there remains little evidence of whether external cortisol use should be subject to exclusion in study subjects. In a group of 209 youth (15-22 year-olds), we analyzed hair and fingernail cortisol concentrations. We assessed topical, nasal, oral, and injectable glucocorticoid use via a questionnaire. Extensively validated methods were used for hair and nail cortisol extraction and measurements. The median value of hair cortisol was 10.2â¯pg/mg (n=200), and the median value of nail cortisol was 7.06â¯pg/mg (n=203). Topical glucocorticoid use significantly increased hair and nail cortisol concentrations (p<0.005). Hair and nail cortisol concentrations were positively associated (p<0.0001, n=194). Spearman correlation coefficients demonstrated that the positive correlation between hair and nail cortisol values was higher in participants who used external glucocorticoids. Topical glucocorticoids moderated the association between hair and nail cortisol values (p=0.006). Based on these findings, we recommend that the assessment of topical glucocorticoid use must be performed when collecting hair/nail samples and that subjects reporting glucocorticoid use should be excluded from all future hair and nail cortisol studies; also, all outliers must be excluded to account for glucocorticoid medication underreporting and yet-unknown confounders.

HIV-related disparities also exist in developing countries, such as the Dominican Republic, where minority groups and/or those with low socioeconomic status experience higher disease burdens and worse health outcomes than those with higher socioeconomic status. We used a community-based approach to ensure the WiseApp intervention is culturally relevant and addresses the needs of our target population. Expert panelists made recommendations on how to simplify the language and features of the WiseApp to accommodate Spanish-speaking users who may have lower levels of education, or color or vision deficiencies.
