Rooted In Family Unity: Advocating For U.S. Citizen Children As Qualifying Relatives, Kevin J. Henriquez

University of the District of Columbia Law Review

This paper advocates for expanding the scope of unlawful presence waivers under § 212(a)(9)(B)(v) of the Immigration and Nationality Act (“INA”) to include U.S. citizen offspring as “qualifying relatives.” Under current law, the waiver only recognizes hardship to U.S. citizens or lawful permanent resident spouses or parents, excluding offsprings entirely despite their central role in family life. This exclusion undermines decades of immigration policy prioritizing family unity and creates devastating consequences for mixed-status families, particularly where U.S. citizens, minors, or adults depend on undocumented parents for financial, emotional, or medical support. This paper traces the statutory and legislative history of …

Criminalizing The Platform: Fosta-Sesta, Internet Governance, And The Erosion Of Online Speech, Fenny Gandhi

University of the District of Columbia Law Review

For decades, sex work operated in the shadows—negotiated in alleyways, mediated by third parties, and shaped by constant risk. Today, much of it happens online, where a screen can mean the difference between autonomy and danger. But, when the law pushes an industry underground, it does not eliminate it; rather, it reshapes how it operates, often in ways that increase vulnerability and reduce accountability. Sex work is the exchange of specific sexual services for money. The experiences of people who engage in sex work are diverse and influenced by social structures and economic realities. The internet provides consensual sex workers …

Deference To Prestige And Climate Policy, Ty’Teona Shannon, Jeffrey Sinn

Athena: Undergraduate Research and Literary Journal

This research addresses the problem of resistance and support for climate mitigation policies. Studies have shown that personal values influence political orientations. However, it needs to be clarified what values motivate individuals to resist climate policies. Using hierarchical regression, we show that Social Dominance Orientation is a significant predictor of climate policy support and that Deference to Prestige does not have a strong relationship with climate policy support. Our findings are significant because they provide additional evidence that ideology and values relate to support for climate mitigation policies.

'Power To Tread On Serpents': Trinity Broadcasting Network And The Theological Underpinnings Of Christian Nationalism, Moriah Coons

Seattle Pacific Seminary Theses

While many scholars have discussed the rise of conservatism and Christian nationalism among prominent American evangelicals since the 1970s, few have seriously discussed the theology which has held up these shifts, especially that which comes from Charismatic influences. This thesis contends that many conservative Christians today, and Pentecostals in particular, cannot be understood according to their political and sociological contexts alone, but require a serious analysis of the theological convictions which drive public engagement. In order to demonstrate the historical justification for this claim, this paper will examine Trinity Broadcasting Network (TBN)’s dissemination of Pentecostal theology between 1973 and 1988, …

Beyond Hipaa: The Ftc’S Expanding Role In Digital Health Privacy Enforcement, Sandhya Srinivasa

SMU Science and Technology Law Review

Consumer digital health platforms have become an increasingly prominent feature of modern health care, collecting and storing sensitive health information directly from users. Yet most of these applications operate outside the scope of the Health Insurance Portability and Accountability Act (HIPAA), creating a significant regulatory gap in the protection of personal health data. This case note examines how the Federal Trade Commission (FTC) has stepped into that gap by leveraging Section 5 of the FTC Act and the Health Breach Notification Rule (HBNR) to police privacy and data security practices among non-HIPAA-covered digital health platforms. Focusing on three landmark enforcement …

Adjunctive Technologies To Electronic Fetal Monitoring: Promise, Pitfalls, And Lessons Learned, Rebecca Horgan, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Despite widespread use, electronic fetal monitoring (EFM) has not demonstrably reduced perinatal morbidity or mortality, and likely contributed to the rise in cesarean delivery. To improve its utility, a number of adjunctive approaches have been introduced over the past three decades, including fetal pulse oximetry, ST segment analysis (STAN), and maternal oxygen supplementation. Each intervention was supported by strong physiologic rationale, yet none achieved widespread clinical adoption due to inconsistent evidence of benefit and, in some cases, potential harm. This review critically evaluates landmark studies on EFM adjuncts, highlights the limitations that have impeded progress, and outlines emerging innovations, including …

The Association Between Maternal-Fetal Medicine Physician Density And Pregnancy Outcomes, Tetsuya Kawakita, Rula Atwani, Misa Hayasaka, Lindsay Robbins, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Objective

We sought to examine the association between maternal-fetal medicine (MFM) physician density and adverse pregnancy outcomes at the state level.

Study Design

This was a cross-sectional analysis of publicly available, state-level data from 2018 to 2021, including Natality, Multiple Cause-of-Death, and Fetal Death databases. The number of active MFM physicians per year was obtained for each state from the American Medical Association Masterfile. The primary exposure was the density of MFM per state, categorized into three groups: (1) low density (< 30 MFM physicians per 100,000 live births), (2) moderate density (30-59 MFM physicians per 100,000 live births), and (3) high density (≥60 MFM physicians per 100,000 live births). Our primary outcome was maternal mortality during pregnancy and up to 42 days postdelivery. Our secondary outcomes were pregnancy-related mortality up to 365 days postdelivery and stillbirth. We calculated adjusted incident rate ratios (aIRR) and average marginal effect (AME) with 95% confidence intervals (95% CI) using multivariable negative binomial mixed effects regression models.

Results

Overall, there were 14,792,743 live births, 3,440 maternal mortalities, 4,980 pregnancy-related mortalities, and 90,848 stillbirths included. The …

Cervicovaginal Lavage Fluid Iron And Manganese Levels In Women With And Without Vaginitis, Barbara Kozma, David Ratonyi, Bence Kozma, Peter Takacs, Attila G. Sipos

Department of Obstetrics & Gynecology Faculty Publications

Transition metals such as iron and manganese are critical for cellular metabolism, redox balance, and immune function, and they also influence host–pathogen interactions. Vaginitis is characterized by mucosal inflammation that may alter local trace-element homeostasis. We hypothesize that inflammatory conditions such as vaginitis may be associated with altered cervicovaginal iron and manganese levels. We performed a prospective, single-center cohort study at the University of Debrecen (Hungary) between April 2023 and April 2024, enrolling 80 women ≥ 18 years with vulvovaginal complaints. Participants were assessed at baseline and at weeks 4, 8, and 12 with clinical evaluation and cervicovaginal lavage (CVL) …

The Taper Sign: Sonographic Representation Of Uterine Dehiscence In Severe Cases Of Placenta Accreta Spectrum, Uma Deshmukh, Anna M. Modest, Alfred Abuhamad, Alireza A. Shamshirsaz, Jonathan L. Hecht, Scott A. Shainker

Department of Obstetrics & Gynecology Faculty Publications

Introduction: Prenatal diagnosis of placenta accreta spectrum (PAS) depends on reliable ultrasound markers and skilled image interpretation. Existing PAS markers emphasize placental features suggestive of abnormal adherence and require advanced image optimization. However, emerging hypotheses suggest that uterine dehiscence—not placental invasion—is the central mechanism underlying PAS, particularly in severe (Grade 3) disease. Despite this, few established ultrasound markers address this uterine dehiscence. We describe a novel ultrasound marker, the taper sign, which uniquely represents the uterine dehiscence in severe PAS with anterior placenta previa, and outline a standardized technique for image acquisition and interpretation.

Methods: This descriptive report details the …

Osmotic Dilators Vs. Foley Balloons: Bayesian Secondary Analyses Of The Dilafol Trial, Antonio F. Saad, Elenir B. C. Avritscher, Claudia Pedroza, Xiao Han, George R. Saade

Department of Obstetrics & Gynecology Faculty Publications

Background: Dilapan-S, a synthetic osmotic dilator used for pre-induction cervical ripening, has proven to be as effective as the Foley balloon in terms of vaginal versus cesarean delivery and has been associated with increased patient satisfaction. Nevertheless, its ability to lower cesarean rates and its cost-effectiveness remain poorly studied.

Objectives: To estimate the likelihood that synthetic osmotic dilators reduce cesarean deliveries and to evaluate their health system costs (2026 US$) and incremental cost-effectiveness compared to the Foley balloon during cervical ripening.

Study Design: Secondary Bayesian analyses were conducted using data from the single-center DILAFOL randomized controlled trial, which enrolled 419 …

Vaginal Pra1 Identifies Clinically Relevant Candida Albicans Vaginitis And Excludes Asymptomatic Colonization: An Exploratory Study, Elena Roselletti, Barbara Kozma, David Ratonyi, Alexandra Kunkli, Bence Kozma, Peter Takacs, Duncan Wilson

Department of Obstetrics & Gynecology Faculty Publications

Background

Accurate interpretation of Candida detection in women with vulvovaginal symptoms remains difficult, because organism recovery may reflect either clinically relevant infection or nonpathogenic colonization. We have recently demonstrated that the secreted fungal zinc-binding protein, Pra1 is responsible for driving the inflammatory immunopathology of VVC. We therefore reasoned that PRA1 expression by Candida albicans in the vagina may act as a diagnostic tool to discriminate between commensal colonisation and active disease.

Methods

We conducted a 12-week prospective, single-center exploratory biomarker analysis nested within a registered parent clinical trial. Nine women with vulvovaginal symptoms provided cervicovaginal lavage samples and clinical data …

Risk Of Gestational Diabetes By Aerobic And Resistance Exercise During The First And Second Trimesters, Takaki Tanamoto, George Saade, Leryn J. Reynolds, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

Objective

While some studies have shown that exercise reduces the incidence of gestational diabetes mellitus (GDM), there is limited evidence on whether aerobic or resistance exercise is more beneficial. This study aimed to examine the rate of GDM according to the type of exercise during early pregnancy.

Study design

We analyzed data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b), a prospective cohort of individuals enrolled during the first and second trimesters. We excluded participants with pregestational diabetes or delivery < 20 weeks. The primary exposure was either aerobic or resistance exercises in the first or second trimester. For each trimester, the metabolic equivalent of task hours per week (MET-h/week) was calculated for each exercise. Participants were grouped as follows: "Aerobic exercise" (≥7.5 MET-h/week from aerobic exercises), "Resistance exercise" (≥2 times/week from resistance exercises), "Both types of exercise" (≥7.5 MET-h/week from aerobic exercise and ≥2 times/week from resistance exercises), and "Insufficient exercise" (≤7.5 MET-h/week from aerobic exercise and ≤2 times/week from resistance exercises). Our primary outcome was GDM. Adjusted relative risks (aRRs) with 95% confidence intervals (95% CIs) were calculated using modified Poisson regression, adjusting for potential confounders.

Results

In both the first and second trimesters, analyses included 9049 individuals. In the first trimester, individuals who performed …
