Challenges and barriers to WIC participation vary by participation status and language: Findings from focus groups in Missouri.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is one of the largest federal food and nutrition program serving women and young children and has a low coverage rate of about 50 percent. There is no peer-reviewed article that compares maternal perceptions of challenges and barriers to WIC participation by language and participation status. We compare challenges and barriers faced by English-speaking mothers to those faced by Spanish-speaking mothers to enrollment and retention in WIC within each group: current participants (n = 43), prior participants (dropouts; n = 27), and eligible non-participants (n = 18), using focus groups we conducted in Missouri in 2021-2023.

Study Design:  Retrospectively, we identified all singletons at term who had CDs.

A Novel Non-Invasive Murine Model of Neonatal Hypoxic-Ischemic Encephalopathy Demonstrates Developmental Delay and Motor Deficits with Activation of Inflammatory Pathways in Monocytes.

Neonatal hypoxic-ischemic encephalopathy (HIE) occurs in 1.5 per 1000 live births, leaving affected children with long-term motor and cognitive deficits. Few animal models of HIE incorporate maternal immune activation (MIA) despite the significant risk MIA poses to HIE incidence and diagnosis.

Second-Trimester Ultrasound Receipt Mediates the Relationship Between Public Insurance and Prenatal Diagnosis of a Congenital Heart Defect.

Objective: To delineate the mechanism behind insurance-related disparities in the prenatal diagnosis of a congenital heart defect (CHD).

Methods: This was a retrospective analysis of electronic health records of pregnant individuals whose infants received CHD surgery between 2019 and 2020 in the third-largest United States metropolitan area. The outcome was whether a prenatal diagnosis was received.

Characterizing medical decision-making in sickle cell disease during childhood: Qualitative perspectives of caregivers.

Introduction: Sickle cell disease (SCD) is the most common genetic disorder among children. As the most common type of SCD, sickle cell anemia (SCA) is associated with severe complications across the lifespan. As parents/caregivers hold primary disease management responsibility during childhood, their involvement in disease management activities, including medical decision-making, is critical to successful and timely management of pediatric SCD.

Nulliparous Individuals with Class III Obesity: Adverse Outcomes with Labor versus Planned Cesarean Delivery.

Objective:  Individuals with class III obesity (body mass index [BMI] ≥ 40 kg/m) are at increased risk of cesarean delivery (CD) and peripartum complications. We ascertained compositive neonatal and maternal adverse outcomes among individuals with class III obesity who labored versus had planned CD.

Study Design:  This was a retrospective cohort study from 2016 to 2021 using the National Vital Statistics System database.

A Validated Calculator to Estimate Risk of Chorioamnionitis in Laboring and Induced Patients at Term.

Objective:  Chorioamnionitis is associated with neonatal morbidity and infection-related mortality, but our ability to predict intrapartum infection is limited. We sought to derive and validate a prediction model for chorioamnionitis among patients presenting to labor and delivery at term.

Study Design:  This was a planned secondary analysis of a large cohort study from 2014 through 2018 at an academic tertiary care center.

Effects of Antihypertensive Therapy During Pregnancy on Postpartum Blood Pressure Control.

Objective: To compare differences in postpartum blood pressure (BP) control (BP below 140/90 mm Hg) for participants with hypertension randomized to receive antihypertensive treatment compared with no treatment during pregnancy.

Methods: This study was a planned secondary analysis of a multicenter, open-label, randomized controlled trial (The CHAP [Chronic Hypertension and Pregnancy] trial). Pregnant participants with mild chronic hypertension (BP below 160/105 mm Hg) were randomized into two groups: active (antihypertensive treatment) or control (no treatment unless severe hypertension, BP 160/105 mm Hg or higher).

Impact of Skin Care Products on Phthalates and Phthalate Replacements in Children: the ECHO-FGS.

Background: Phthalates and their replacements have been implicated as developmental toxicants. Young children may be exposed to phthalates/replacements when using skin care products (SCPs).

Objectives: Our objective is to assess the associations between use of SCPs and children's urinary phthalate/replacement metabolite concentrations.
