Innate immunity predictors of HIV-1 risk and pathogenesis vary with reproductive hormones, pregnancy, and lactation, yet the underlying mechanisms remain unclear. We hypothesized that pregnancy-associated physiological adaptations alter systemic microRNA (miRNA) expression, thereby regulating immunity, pathogenesis and susceptibility to infection. We analyzed 174 serum samples from 88 participants in a longitudinal cohort from Uganda and Zimbabwe across pre-pregnancy (PP), pregnancy (P), and postpartum breastfeeding (BF). Cell-free peripheral blood miRNAs (n = 2083) were profiled using HTG EdgeSeq. Pregnancy-specific miRNAs were identified by intersecting differentially expressed (DE) miRNAs from P vs. PP and P vs. BF comparisons. miRNA targets and pathways …

BACKGROUND: Anemia among women of reproductive age has remained highly prevalent globally. Intravenous (IV) iron is well tolerated and proven effective for treating postpartum iron deficiency anemia in high-income countries, but evidence from LMICs, where oral iron is standard treatment, is limited. The PRIORITY trial will test the effectiveness of IV iron compared to oral iron for postpartum women with moderate anemia in eight LMIC sites. An implementation research (IR) study will be conducted alongside the PRIORITY trial in India and Pakistan to gather information on the intervention characteristics and the implementation process, and to assess feasibility, acceptability, fidelity, and …

Objectives: Evaluate associations between maternal perceived stress and depressive symptoms, and fetal body composition and organ volumes.
Methods: In the NICHD Fetal 3D Study (2015-2019; n = 2457), stress and depressive symptoms were assessed at enrollment (10-13 weeks). High stress was defined as a Perceived Stress Scale (PSS) score ≥15 and high depressive symptoms, defined as an Edinburgh Postnatal Depression Scale (EPDS) score ≥10. Fetal body composition and organ volumes (cerebellar, lung, liver, and kidney) were measured up to five times between 15 and 40 weeks using three-dimensional (3D) ultrasound technology. Trajectories of body composition and organ volumes across pregnancy …

Identifying the ureters in patients with advanced endometriosis and severe pelvic adhesive disease can be challenging. Adhesiolysis along the deformed pelvic sidewall may increase the risk of prolonged operative time and incidental ureteral injury. This study aimed to evaluate the safety and surgical outcomes of using Indocyanine Green (ICG) under near-infrared fluorescence for intraoperative ureteral localization and preservation during robot-assisted laparoscopic surgery (RALS) for advanced endometriosis, comparing procedures performed by two junior surgeons to those performed by one senior surgeon. This was a retrospective observational case series conducted by three minimally invasive gynecologic surgeons (X.G., T.K., B.T.) at a single …

Importance: An emerging paradigm attributes third-trimester fetal growth deceleration in uncomplicated twin pregnancies to an evolutionary adaptive process. Evaluating longitudinal fetal soft-tissue development may provide important insights into differential fetal growth trajectories between twins and singletons.
Objective: To compare twin vs singleton lean and fat tissue growth across pregnancy.
Design, setting, and participants: Prospective cohort study of dichorionic twins and singletons with serial ultrasound scans to chart fetal growth (2009-2013) and collect fetal volume data to measure fat and lean tissue (2015-2019) in 12 US clinical centers. Participants were individuals with singleton (n = 2802 enrolled) and twin (n = …

Background: The effects of SARS-CoV-2 infection before or during pregnancy on pregnancy outcomes are still largely unknown. We hypothesized that COVID-19 in early pregnancy is a risk factor for adverse pregnancy outcomes, particularly miscarriage.
Methods: We examined the relationship between COVID-19 and adverse pregnancy outcomes, including spontaneous abortion, ectopic pregnancy, and preterm delivery in a large, retrospective, electronic health record (EHR)-based cohort, from 2019 to 2023. Generalized estimating equation modeling was performed to identify risk factors for adverse pregnancy outcomes. Study exposures included COVID-19 before pregnancy, COVID-19 during pregnancy, age, race/ethnicity, comorbidity burden, and neighborhood-level social vulnerability.
Results: In the …

BACKGROUND: Africa has a high burden of congenital anomalies due in part to limited preconception care, infections, and environmental exposures. However, the true prevalence of congenital anomalies is unclear because of insufficient access to prenatal diagnostic services. We aimed to determine the rate of congenital anomalies, and characterize the anomalies detected prenatally at a referral hospital in Ghana.
METHODS: We performed a four-year retrospective review of all fetal anomaly ultrasounds performed and congenital anomalies detected from January 1st, 2020, to December 31st, 2023, at Korle Bu Teaching Hospital, Accra, Ghana. Data were extracted from the electronic database on maternal age, …

Hypertensive disorders of pregnancy (HDP), including preeclampsia, affect 1 in 6 pregnancies, are major contributors to maternal morbidity and mortality, yet lack precision medicine strategies. Analyzing transcriptomic data from a prospectively-collected diverse cohort (n = 9102), this study reveals distinct RNA subtypes in maternal blood, reclassifying clinical HDP phenotypes like early/late-onset preeclampsia. The placental gene PAPPA2 strongly predicts the most severe forms of preeclampsia in individuals without pre-existing high risk factors, months before symptoms, and its overexpression correlates with earlier delivery in a dose-dependent manner. Further, molecular subtypes characterized by immune genes are upregulated in less severe forms of HDP. …
