RESUMO

BACKGROUND: Randomized trials of assisted reproductive technology (ART) have been designed for outcomes of clinical pregnancy or live birth and have not been powered for obstetric outcomes such as preeclampsia, critical for maternal and fetal health. ART increasingly involves frozen embryo transfer (FET). Although there are advantages of FET, multiple studies have shown that risk of preeclampsia is increased with FET compared with fresh embryo transfer, and the reason for this difference is not clear. NatPro will compare the proportion of preeclampsia between two commonly used protocols for FET,modified natural and programmed cycle. METHODS: In this two-arm, parallel-group, multi-center randomized trial, NatPro will randomize 788 women to either modified natural or programmed FET and follow them for up to three FET cycles. Primary outcome will be the proportion of preeclampsia in women with a viable pregnancy assigned to a modified natural cycle FET (corpus luteum present) protocol compared to the proportion of preeclampsia in pregnant women assigned to a programmed FET (corpus luteum absent) protocol. Secondary outcomes will compare the proportion of live births and the proportion of preeclampsia with severe features between the protocols. CONCLUSION: This study has a potential significant impact on millions of women who pursue ART to build their families. NatPro is designed to provide clinically relevant guidance to inform patients and clinicians regarding maternal risk with programmed and modified natural cycle FET protocols. This study will also provide accurate point estimates regarding the likelihood of live birth with programmed and modified natural cycle FET. TRIAL REGISTRATION: ClinicalTrials.gov NCT04551807 .

RESUMO

BACKGROUND: Acceptability is a critical requisite in establishing feasibility when planning a larger effectiveness trial. This study assessed the acceptability of conducting a feasibility randomized clinical trial of a 20-week microenterprise intervention for economically-vulnerable African-American young adults, aged 18 to 24, in Baltimore, Maryland. Engaging MicroenterprisE for Resource Generation and Health Empowerment (EMERGE) aimed to reduce sexual risk behaviors and increase employment and uptake of HIV preventive behaviors. METHODS: Thirty-eight participants were randomized to experimental (n = 19) or comparison group (n = 19). The experimental group received text messages on job openings plus educational sessions, mentoring, a start-up grant, and business and HIV prevention text messages. The comparison group received text messages on job openings only. Qualitative and quantitative post-intervention, in-person interviews were used in addition to process documentation of study methods. RESULTS: Our results found that the study design and interventions showed promise for being acceptable to economically-vulnerable African-American young adults. The largely positive endorsement suggested that factors contributing to acceptability included perceived economic potential, sexual health education, convenience, incentives, and encouraging, personalized feedback to participants. Barriers to acceptability for some participants included low cell phone connectivity, perceived payment delays, small cohort size, and disappointment with one's randomization assignment to comparison group. Use of peer referral, network, or wait-list designs, in addition to online options may enhance acceptability in a future definitive trial. Expanding administrative and mentoring support may improve overall experience. CONCLUSION: Microenterprise interventions are acceptable ways of providing young adults with important financial and sexual health content to address HIV risks associated with economic vulnerability.

RESUMO

Economic vulnerability, such as homelessness and unemployment, contributes to HIV risk among U.S. racial minorities. Yet, few economic-strengthening interventions have been adapted for HIV prevention in this population. This study assessed the feasibility of conducting a randomized clinical trial of a 20-week microenterprise intervention for economically-vulnerable African-American young adults. Engaging MicroenterprisE for Resource Generation and Health Empowerment (EMERGE) aimed to reduce sexual risk behaviors and increase employment and uptake of HIV preventive behaviors. The experimental group received text messages on job openings plus educational sessions, mentoring, a start-up grant, and business and HIV prevention text messages. The comparison group received text messages on job openings only. Primary feasibility objectives assessed recruitment, randomization, participation, and retention. Secondary objectives examined employment, sexual risk behaviors, and HIV preventive behaviors. Outcome assessments used an in-person pre- and post-intervention interview and a weekly text message survey. Several progression criteria for a definitive trial were met. Thirty-eight participants were randomized to experimental (n = 19) or comparison group (n = 19) of which 95% were retained. The comparison intervention enhanced willingness to be randomized and reduced non-participation. Mean age of participants was 21.0 years; 35% were male; 81% were unemployed. Fifty-eight percent (58%) of experimental participants completed ≥ 70% of intervention activities, and 74% completed ≥ 50% of intervention activities. Participation in intervention activities and outcome assessments was highest in the first half (~ 10 weeks) of the study. Seventy-one percent (71%) of weekly text message surveys received a response through week 14, but responsiveness declined to 37% of participants responding to ≥ 70% of weekly text message surveys at the end of the study. The experimental group reported higher employment (from 32% at baseline to 83% at week 26) and lower unprotected sex (79% to 58%) over time compared to reported changes in employment (37% to 47%) and unprotected sex (63% to 53%) over time in the comparison group. Conducting this feasibility trial was a critical step in the process of designing and testing a behavioral intervention. Development of a fully-powered effectiveness trial should take into account lessons learned regarding intervention duration, screening, and measurement.Trial Registration ClinicalTrials.gov.

RESUMO

BACKGROUND: Transgender women ("trans women"), particularly African-American and Latina trans women, have disproportionately high prevalence of HIV in the United States (U.S.). In order to decrease gender dysphoria and overcome discrimination, trans women affirm their gender through social and medical transition, often in contexts of economic hardship and sexual risk. This study qualitatively examined how gender-affirming behaviors enhance or diminish vulnerability to HIV in light of structural and economic barriers to gender transition. METHODS: We conducted individual interviews with 19 adult trans women in two U.S. cities (Richmond, VA and St. Louis, MO) who reported one or more sexual risk behaviors and recent economic hardship related to employment/income, housing, or food security. Interviews were recorded, transcribed, and analyzed using thematic content analysis. RESULTS: The majority (74%) of trans women were racial/ethnic minorities with mean age of 26.3 years. Gender-affirming behaviors varied with 58% of trans women having legally changed their name and gender marker; 79% having initiated hormone therapy; and 11% having not initiated any medical or legal changes. None had undertaken surgical changes. Findings suggested that the process of gender transitioning resulted in both increasing and decreasing HIV risk. The high need for gender affirmation by male sex partners contributed to trans women's exposure to sexual objectification, sexual risk behaviors, and conflicting interests in HIV prevention messaging. Loss of housing and employment due to transition along with the high costs of transition products and medical visits increased reliance on sex work and created new obstacles in accessing HIV services. Trans women experienced lower HIV risk as they acquired legal and medical transition services, reshaped interactions with sex partners, and received gender-affirming support by others, including health providers, employers, peers, and housing professionals. Sexual abstinence was viewed as a negative consequence of incomplete transition, although characterized as a period of low HIV risk. CONCLUSIONS: Structural and policy initiatives that promote safe gender transition and economic stability in trans women may play a critical role in reducing HIV in this population. Addressing the harmful pressures for U.S. trans women to conform to perceived feminine stereotypes may also serve an important role.

RESUMO

BACKGROUND: Economic vulnerability, such as homelessness and unemployment, contributes to the HIV risk among racial minorities in the U.S., who are disproportionately infected. Yet, few economic-strengthening interventions have been adapted for HIV prevention in economically-vulnerable African-American young adults. Engaging Microenterprise for Resource Generation and Health Empowerment (EMERGE) is a feasibility randomized clinical trial of an HIV prevention microenterprise intervention with integrated text messages ("nudges") that are informed by behavioral economic principles. The trial aims to reduce sexual risk behaviors and increase employment and uptake of HIV preventive behaviors. METHODS/DESIGN: In total, 40 young adults who are African-American, aged 18-24, live in Baltimore City, have experienced at least one episode of homelessness in the last 12 months, are unemployed or underemployed (fewer than 10 h per week), are not enrolled in school, own a cell phone with text messaging, and report at least one episode of unprotected or unsafe sex in the prior 12 months will be recruited from two community-based organizations providing residential supportive services to urban youth. Participants will undergo a 3-week run-in period and thereafter be randomly assigned to one of two groups with active interventions for 20 weeks. The first group ("comparison") will receive text messages with information on job openings. The second group ("experimental") will receive text messages with information on job openings plus information on HIV prevention and business educational sessions, a mentored apprenticeship, and a start-up grant, and business and HIV prevention text messages based on principles from behavioral economics. The two primary outcomes relate to the feasibility of conducting a larger trial. Secondary outcomes relate to employment, sexual risk behaviors, and HIV preventive practices. All participants will be assessed using an in-person questionnaire at pre-intervention (prior to randomization) and at 3 weeks post-intervention. To obtain repeated, longitudinal measures, participants will be assessed weekly using text message surveys from pre-intervention up to 3 weeks post-intervention. DISCUSSION: This study will be one of the first U.S.-based feasibility randomized clinical trials of an HIV prevention microenterprise intervention for economically-vulnerable African-American young adults. The findings will inform whether and how to conduct a larger efficacy trial for HIV risk reduction in this population. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03766165 .
