The Mortality of Congenital Syphilis.

Objectives: To document the case-fatality rate (CFR) of congenital syphilis diagnosed by molecular tools and rabbit infectivity testing (RIT) of clinical specimens in addition to standard evaluation and to compare that with the CFR using the Centers for Disease Control and Prevention (CDC) surveillance case definition.

Study Design: Prospective, single site, cohort study of all cases of syphilis among mothers and their infants from 1984 to 2002. The diagnosis of congenital syphilis was determined using IgM immunoblotting, polymerase chain reaction, and RIT of fetal or infant specimens in addition to clinical, laboratory, and radiographic criteria.

Infant feeding for people living with HIV in high resource settings: a multi-disciplinary approach with best practices to maximise risk reduction.

Shared decision making for infant feeding in the context of HIV in high-resourced settings is necessary to acknowledge patient autonomy, meet increasing patient requests and address the changing reality of perinatal HIV care. In low-to middle-income countries (LMIC), where the majority of individuals living with HIV reside, persons with HIV are recommended to breastfeed their infants. In the setting of maternal anti-retroviral therapy (ART) use throughout pregnancy, viral suppression and appropriate neonatal post-exposure prophylaxis (PEP) use, updated information indicates that the risk of HIV transmission through breastmilk may be between 0.

Women Living with Human Immunodeficiency Virus with Intended and Unintended Pregnancy: Characteristics and Patient Outcomes.

Rates of unintended pregnancy may be higher in women living with human immunodeficiency virus (WLWH) than in the general population, and it is unclear how populations of WLWH with intended and unintended pregnancy differ. We compared baseline characteristics and outcomes between WLWH with intended and unintended pregnancy. We conducted a retrospective analysis of WLWH enrolled in a human immunodeficiency virus (HIV) and Pregnancy clinic from 2003 to 2014.

Findings From Severe Maternal Morbidity Surveillance and Review in Maryland.

Importance: In the US, more than 50 000 women experience severe maternal morbidity (SMM) each year, and the SMM rate more than doubled during the past 25 years. In response, professional organizations called for birthing facilities to routinely identify and review SMM events and identify prevention opportunities.

Objective: To examine SMM levels, primary causes, and factors associated with the preventability of SMM using Maryland's SMM surveillance and review program.

Pulmonary Embolism and Amniotic Fluid Embolism.

Venous thromboembolism (VTE) as well as other embolic events including amniotic fluid embolism (AFE) remain a leading cause of maternal death in the United States and worldwide. The pregnant patient is at a higher risk of developing VTE including pulmonary embolism. In contrast, AFE is a rare, but catastrophic event that remains incompletely understood.

Long-Term Fine Particulate Matter Concentrations and Prevalence of Severe Acute Respiratory Syndrome Coronavirus 2: Differential Relationships by Socioeconomic Status Among Pregnant Individuals in New York City.

We aimed to determine whether long-term ambient concentrations of fine particulate matter (particulate matter with an aerodynamic diameter less than or equal to 2.5 μm (PM2.5)) were associated with increased risk of testing positive for coronavirus disease 2019 (COVID-19) among pregnant individuals who were universally screened at delivery and whether socioeconomic status (SES) modified this relationship.

Improvement of Umbilical Cord Blood Gas Analysis with Implementation of Clot Catchers.

Background: Umbilical cord blood gas testing is a key component of objective pre- and perinatal evaluation of fetal acid base status to determine presence of intrapartum asphyxia and risk of neonatal encephalopathy. Heparinized cord blood is more likely to form small clots than other blood sources, which can interfere with, or preclude, sample analysis. Cord blood samples are irreplaceable and cannot be recollected, thereby compromising clinical decision-making when analysis is not possible.

Development of an Obstetric Hemorrhage Response Intervention: The Postpartum Hemorrhage Cart and Medication Kit.

Background: Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity in the United States, and timely treatment is imperative. Delay in treatment of PPH can lead to significant blood loss and increased morbidity and mortality. Supplies and medications essential for treating PPH are typically not located in close proximity to the hemorrhaging patient, leading to inefficiency and delay in timely response to hemorrhage.

Experience and Outcomes of Breastfed Infants of Women Living With HIV in the United States: Findings From a Single-Center Breastfeeding Support Initiative.

We assessed breastfeeding outcomes for a cohort of infants born to women living with HIV (WLHIV) at an urban health care center in the United States. Ten infants were exclusively breastfed for a mean duration of 4.4 (1.

Pregnancy alters interleukin-1 beta expression and antiviral antibody responses during severe acute respiratory syndrome coronavirus 2 infection.

Background: Severe acute respiratory syndrome coronavirus 2, the disease-causing pathogen of the coronavirus disease 2019 pandemic, has resulted in morbidity and mortality worldwide. Pregnant women are more susceptible to severe coronavirus disease 2019 and are at higher risk of preterm birth than uninfected pregnant women. Despite this evidence, the immunologic effects of severe acute respiratory syndrome coronavirus 2 infection during pregnancy remain understudied.

Evidence-based protocol decreases time to vaginal delivery in elective inductions.

Background: Labor induction accounts for over 1 in 5 births in the United States. There is large variability in practices of induction of labor. Standardizing aspects of induction of labor has been shown to have beneficial maternal and fetal effects.

Dysregulated immunity in SARS-CoV-2 infected pregnant women.

Importance: The effects of SARS-CoV-2 infection on immune responses during pregnancy have not been systematically evaluated.

Objective: To assess the impact of SARS-CoV-2 infection during pregnancy on inflammatory and humoral responses in maternal and fetal samples and compare antibody responses to SARS-CoV-2 among pregnant and non-pregnant women.

Design: Immune responses to SARS-CoV-2 were analyzed using samples from pregnant and non-pregnant women who had either tested positive or negative for SARS-CoV-2.

Compassionate Use of Remdesivir in Pregnant Women With Severe Coronavirus Disease 2019.

Background: Remdesivir is efficacious for severe coronavirus disease 2019 (COVID-19) in adults, but data in pregnant women are limited. We describe outcomes in the first 86 pregnant women with severe COVID-19 who were treated with remdesivir.

Methods: The reported data span 21 March to 16 June 2020 for hospitalized pregnant women with polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection and room air oxygen saturation ≤94% whose clinicians requested remdesivir through the compassionate use program.

Severity of COVID-19 in pregnancy: A review of current evidence.

Coronavirus disease 19 (COVID-19) has recently emerged as a major threat to human health. Infections range from asymptomatic to severe (increased respiratory rate, hypoxia, significant lung involvement on imaging) or critical (multi-organ failure or dysfunction or respiratory failure requiring mechanical ventilation or high-flow nasal cannula). Current evidence suggests that pregnancy women are at increased risk of severe disease, specifically the need for hospitalization, ICU admission, and mechanical ventilation, and the already complex management of infection with an emerging pathogen may be further complicated by pregnancy.

Tenofovir alafenamide use in pregnant and lactating women living with HIV.

: Tenofovir alafenamide (TAF)-containing fixed-dose drug combinations (FDCs) are increasingly being used in managing pregnant women living with HIV. However, TAF is not currently recommended during pregnancy due to limited pharmacokinetic and safety data. TAF, a newer nucleotide phosphonamidate prodrug of tenofovir (TFV), achieves high levels of tenofovir-diphosphate in lymphoid cells and hepatocytes, and 90% lower systemic concentrations of TFV compared to tenofovir disoproxil fumarate (TDF), thereby maximizing TAF's antiviral efficacy, potency and clinical safety.

Detecting Patterns of Prescription Drug Use During Pregnancy and Lactation with Visualization Techniques.

Background: Pharmacovigilance studies for the pregnancy population are an important tool to address the teratogenic and maternal effects of prescription drugs.

Objectives: We sought to leverage existing data to provide empirical evidence that reflects current drug utilization by pregnant/lactating women for pharmacovigilance and effective study designs.

Methods: Temporal patterns of prescription drug use during pregnancy and lactation for four clinical conditions were visualized using a R package and an administrative claims dataset representing nationwide privately-insured women.

Pregnant women & vaccines against emerging epidemic threats: Ethics guidance for preparedness, research, and response.

Zika virus, influenza, and Ebola have called attention to the ways in which infectious disease outbreaks can severely - and at times uniquely - affect the health interests of pregnant women and their offspring. These examples also highlight the critical need to proactively consider pregnant women and their offspring in vaccine research and response efforts to combat emerging and re-emerging infectious diseases. Historically, pregnant women and their offspring have been largely excluded from research agendas and investment strategies for vaccines against epidemic threats, which in turn can lead to exclusion from future vaccine campaigns amidst outbreaks.

IL-1 receptor antagonist therapy mitigates placental dysfunction and perinatal injury following Zika virus infection.

Zika virus (ZIKV) infection during pregnancy causes significant adverse sequelae in the developing fetus, and results in long-term structural and neurologic defects. Most preventive and therapeutic efforts have focused on the development of vaccines, antivirals, and antibodies. The placental immunologic response to ZIKV, however, has been largely overlooked as a target for therapeutic intervention.

Simulation of a Spontaneous Vaginal Delivery and Neonatal Resuscitation in a Biocontainment Unit.

This article describes a large-scale scenario designed to test the capabilities of a US biocontainment unit to manage a pregnant woman infected with a high-consequence pathogen, and to care for a newborn following labor and spontaneous vaginal delivery. We created and executed a multidisciplinary functional exercise with simulation to test the ability of the Johns Hopkins Hospital biocontainment unit (BCU) to manage a pregnant patient in labor with an unknown respiratory illness and to deliver and stabilize her neonate. The BCU Exercise and Drill Committee established drill objectives and executed the exercise in partnership with the Johns Hopkins Simulation Center in accordance with Homeland Security and Exercise Program guidelines.
