Engaging sexual minority adolescents in nationwide at-home HIV prevention research in the U.S.

Objectives: This study examined research-related privacy and confidentiality concerns among adolescent sexual minority males (ASMM) and provides lessons learned to inform recruitment and enrollment strategies for this population.

Methods: Participants were a 2017-2018 internet-based U.S.

Implementing a Labor and Delivery Cell Salvage Protocol in Patients at Increased Risk of Hemorrhage: A Pilot Study.

Background: Postpartum hemorrhage (PPH) contributes significantly to maternal morbidity and mortality. The use of cell salvage has been implemented in operating rooms across the world, but only a limited number of institutions have protocols for use of cell salvage during vaginal hemorrhage at the time of vaginal delivery. Observations suggest that blood salvaged from vaginal delivery is comparable to blood salvaged during cesarean delivery.

The Effect of Implicit Bias on the OB/GYN Residency Application Process.

Medical students from racially minoritized backgrounds receive negative evaluations more frequently, possibly from implicit bias. To determine if a preference for White applicants over Asian and Black applicants exists among resident and attending reviewers of obstetrics and gynecology (OB/GYN) residency applications. In 2021, we sampled academic OB/GYN physicians from 6 academic institutions to randomly receive questionnaire form A or B, each containing 4 contrived Electronic Residency Application Service profiles stratified by United States Medical Licensing Examination scores; institutions attended; and strength of recommendation letters into top-, mid-, and low-tiers.

Examining the predictive value of fetal fraction on hypertensive disorders of pregnancy.

Background: Cell-free fetal DNA (cffDNA) screening is routinely performed in pregnancy. Abnormal fetal fraction has been associated with adverse pregnancy outcomes, including hypertensive disorders of pregnancy, which are associated with severe maternal and neonatal morbidity and mortality.

Objective: This study examined whether abnormal fetal fraction, defined in this study as fetal fraction either <6 or >15 on the basis of restricted-cubic-spline-plot within our study population, was associated with HDP in a retrospective sample, as well as whether fetal fraction improves the prediction of hypertensive disorders of pregnancy (HDP).

Implementation of an Enhanced Prenatal Checklist to Increase Rates of Counseling of Prenatal Fetal Aneuploidy Testing.

Aim This study aims to assess the effect of implementing an enhanced prenatal genetic checklist to guide the provider's discussion on both screening and diagnostic options for fetal aneuploidy testing at the initial prenatal visit. Methods A retrospective quality improvement (QI) project was performed at a single, large, urban academic medical center. The implementation of this project was prospective; however, data was examined retrospectively after the QI initiative was implemented for three months.

Examining provider practice-level disparities in delivery outcomes among patients with a history of Cesarean Delivery.

Background: Choosing whether to pursue a trial of labor after cesarean (TOLAC) or scheduled repeat cesarean delivery (SRCD) requires prenatal assessment of risks and benefits. Providers and patients play a central role in this process. However, the influence of provider-associated characteristics on delivery methods remains unclear.

Noninvasive single-cell-based prenatal genetic testing: A proof of concept clinical study.

Objective: To clinically assess a cell-based noninvasive prenatal genetic test using sequence-based copy number analysis of single trophoblasts from maternal blood.

Methods: Blood was obtained from 401 (243 + 158) individuals (8-22 weeks) and shipped overnight. Red cells were lysed, and nucleated cells stained for cytokeratin (CK) and CD45 and enriched for positive CK staining.

Preoperative Application of Chlorhexidine to Reduce Infection with Cesarean Delivery after Labor (PRACTICAL): A Randomized Clinical Trial.

Objective: To evaluate whether use of both preoperative 2% chlorhexidine gluconate abdominal cloth and 4% chlorhexidine gluconate vaginal scrub is effective in reducing surgical site infections (SSIs) in patients undergoing cesarean delivery after labor.

Study Design: This is a single-center, randomized clinical trial in which patients were randomized 1:1 to receive 2% chlorhexidine gluconate cloth applied to the abdomen in addition to the application of 4% chlorhexidine gluconate vaginal scrub versus standard of care. The primary outcome was rate of SSIs, including endometritis, by 6 weeks postdelivery.

Examining inequities in rates of undiagnosed HIV and rectal STIs in a large nationwide cohort study of sexual minority men.

Objective: Sexual minority men (SMM) of colour are disproportionately impacted by HIV and bacterial STIs (bSTIs). To better understand within-group heterogeneity and differential risk factors by race and ethnicity, we sought to examine rates of undiagnosed HIV and rectal bSTI at the intersection of racial and ethnic identity with other sociodemographic factors.

Methods: We examined data from 8105 SMM conducting home-based self-testing at enrolment in a nationwide cohort study collected from November 2017 to August 2018.

Leveraging Technology to Blend Large-Scale Epidemiologic Surveillance With Social and Behavioral Science Methods: Successes, Challenges, and Lessons Learned Implementing the UNITE Longitudinal Cohort Study of HIV Risk Factors Among Sexual Minority Men in the United States.

The use of digital technologies to conduct large-scale research with limited interaction (i.e., no in-person contact) and objective endpoints (i.
