The role of neighborhood deprivation in the cervicovaginal microbiota.

Background: Lactobacillus-deficient cervicovaginal microbiota is associated with spontaneous preterm birth and is more common among Black individuals. Persistent racial segregation in the United States has led to differential neighborhood exposures by race that can affect pregnancy outcomes. The extent to which neighborhood exposures may explain racial differences in the cervicovaginal microbiota is unknown.

Clinician-reported childbirth outcomes, patient-reported childbirth trauma, and risk for postpartum depression.

Childbirth trauma is common and increases risk for postpartum depression (PPD). However, we lack brief measures to reliably identify individuals who experience childbirth trauma and who may be at greater prospective risk for PPD. To address this gap, we used data from a racially diverse prospective cohort (n=1082).

Prospective Evaluation of Cardiovascular Risk 10 Years After a Hypertensive Disorder of Pregnancy.

Background: Hypertensive disorders of pregnancy (HDP) are associated with increased risk of cardiovascular disease (CVD) 20-30 years later; however, cardiovascular (CV) risk in the decade after HDP is less studied.

Objectives: The purpose of this study was to evaluate differences in CV risk factors as well as subclinical CVD among a well-characterized group of racially diverse patients with and without a history of HDP 10 years earlier.

Methods: This is a prospective study of patients with and without a diagnosis of HDP ≥10 years earlier (2005-2007) who underwent in-person visits with echocardiography, arterial tonometry, and flow-mediated dilation of the brachial artery.

Association of COVID-19 and Endemic Systemic Racism With Postpartum Anxiety and Depression Among Black Birthing Individuals.

Importance: The intersection of endemic structural racism and the global health crisis secondary to the COVID-19 pandemic represents a syndemic, defined as the aggregation of 2 or more endemic and epidemic conditions leading to adverse repercussions for health. Long-standing inequities have placed Black individuals at disproportionate risk for negative postpartum mental health outcomes. Studies are urgently needed to understand how the COVID-19 pandemic has added to this risk (eg, syndemic associations).

Risk And Resilience Factors Influencing Postpartum Depression And Mother-Infant Bonding During COVID-19.

Acute stress during pregnancy can have adverse effects on maternal health and increase the risk for postpartum depression and impaired mother-infant bonding. The COVID-19 pandemic represents an acute environmental stressor during which it is possible to explore risk and resilience factors that contribute to postpartum outcomes. To investigate prenatal risk and resilience factors as predictors of postpartum depression and impaired mother-infant bonding, this study recruited a diverse cohort of 833 pregnant women from an urban medical center in Philadelphia, Pennsylvania, and assessed them once during pregnancy in the early phase of the COVID-19 pandemic (April-July 2020) and again at approximately twelve weeks postpartum.

Maternal perceived stress and the increased risk of preterm birth in a majority non-Hispanic Black pregnancy cohort.

Objective: To determine whether perceived stress is associated with preterm birth (PTB) and to investigate racial differences in stress and PTB.

Study Design: A secondary analysis of a prospective cohort study of 1911 women with singleton pregnancies examined responses to psychosocial stress questionnaires at 16-20 weeks of gestation.

Results: High perceived stress (19%) and PTB (10.

Genetic and Phenotypic Landscape of Peripartum Cardiomyopathy.

Background: Peripartum cardiomyopathy (PPCM) occurs in ≈1:2000 deliveries in the United States and worldwide. The genetic underpinnings of PPCM remain poorly defined. Approximately 10% of women with PPCM harbor truncating variants in (TTNtvs).

The Disproportionate Burden of the COVID-19 Pandemic Among Pregnant Black Women.

The COVID-19 pandemic has disproportionately impacted the well-being of vulnerable populations in the US, including Black people. The impact on pregnant women is of special concern for the intrauterine and post-natal development of their offspring. We evaluated in an online survey a sample of 913 pregnant women, 216 Black, 571 White, 126 Other, during a 2-week stay-at-home mandate in the Philadelphia region.

Maternal stress, low cervicovaginal β-defensin, and spontaneous preterm birth.

Background: Spontaneous preterm birth (sPTB) is a major contributor to infant mortality and its etiology remains poorly understood. Host immunity and maternal stress may play a role in the pathogenesis of sPTB but mechanisms are poorly delineated. Antimicrobial proteins in the cervicovaginal space, such as beta defensins, modulate immune responses to bacteria and have been shown to modulate the risk of sPTB from non-optimal microbiota.

Safe Start Community Health Worker Program: A Multisector Partnership to Improve Perinatal Outcomes Among Low-Income Pregnant Women With Chronic Health Conditions.

Safe Start is a community health worker program representing a partnership between a high-volume, inner-city, hospital-based prenatal clinic; a community-based organization; a large Medicaid insurer; and a community behavioral health organization to improve perinatal outcomes among publicly insured pregnant women with chronic health conditions in Philadelphia, Pennsylvania. As of June 2019, 291 women participated in the program. Relative to a comparison group (n = 300), Safe Start participants demonstrate improved engagement in care, reduced antenatal inpatient admissions, and shorter neonatal intensive care unit stays.

Cervicovaginal microbiota and local immune response modulate the risk of spontaneous preterm delivery.

Failure to predict and understand the causes of preterm birth, the leading cause of neonatal morbidity and mortality, have limited effective interventions and therapeutics. From a cohort of 2000 pregnant women, we performed a nested case control study on 107 well-phenotyped cases of spontaneous preterm birth (sPTB) and 432 women delivering at term. Using innovative Bayesian modeling of cervicovaginal microbiota, seven bacterial taxa were significantly associated with increased risk of sPTB, with a stronger effect in African American women.

Comparison of Clinical Characteristics and Outcomes of Peripartum Cardiomyopathy Between African American and Non-African American Women.

Importance: Peripartum cardiomyopathy (PPCM) disproportionately affects women of African ancestry, but well-powered studies to explore differences in severity of disease and clinical outcomes are lacking.

Objective: To compare the clinical characteristics, presentation, and outcomes of PPCM between African American and non-African American women.

Design, Setting, And Participants: This retrospective cohort study using data from January 1, 1986, through December 31, 2016, performed at the University of Pennsylvania Health System, a tertiary referral center serving a population with a high proportion of African American individuals, included 220 women with PPCM.
