Between 2008 and 2016, 23% of pregnancy-related deaths in Ohio occurred in an emergency department (ED) or outpatient setting. Prior research showed that 98% of Ohio's delivery hospitals conduct obstetric (OB) emergency simulations, whereas only 30% include ED staff. The goal of the grant was to increase the knowledge, skill, and self-efficacy of emergency medicine (EM) professionals in managing OB emergencies.

With the onset of the COVID-19 pandemic, telehealth became a widely used method to provide patient care. Providers had to quickly learn how to adapt traditional clinical care to the virtual environment. The existing literature focuses on the technological aspects of telehealth with only a few publications addressing optimization of communication, with even fewer looking at the use of simulation to fill the knowledge gap in this area.

Background: Gestational diabetes mellitus (GDM), a common complication of pregnancy, is associated with a 10-fold increased risk of type 2 diabetes mellitus (T2DM) compared to the general population. Evidence-based guidelines recommend that patients with GDM receive postpartum care for T2DM risk reduction including an oral glucose tolerance test (OGTT) 4-12 weeks after delivery, yet half of patients with GDM did not return for their postpartum visits by 12 weeks postpartum. Additionally, only 10% utilize primary care within 12 months of delivery and one-third of GDM patients receive timely postpartum OGTT.

Introduction: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-associated hepatic disorder characterized by pruritus in the setting of elevated serum bile acids (BA). Risk factors for the disease include preexisting hepatobiliary disease, personal or family history of ICP, and advanced maternal age. Recent data suggests that patients with severe ICP (BA ≥100 μmol/L) have a higher risk of adverse pregnancy outcomes including stillbirth.

Background: A proposed benefit of cervical length assessment after 24 weeks' gestation in women with a history of preterm birth is to aid in the timing of antenatal corticosteroids in otherwise asymptomatic women.

Objective: We sought to investigate whether the use of an ultrasonographic short cervical length as an indication for antenatal corticosteroids in asymptomatic women results in optimal exposure compared with women receiving antenatal corticosteroids for preterm labor symptoms.

Study Design: Retrospective cohort study of all women with a previous spontaneous preterm birth and a singleton gestation who underwent serial cervical length assessment at a large academic tertiary medical center from 2011 to 2016.

Article Synopsis
  • Preeclampsia (PE) is a pregnancy condition affecting blood vessels and can impact various organs, including the kidneys of mothers and possibly fetuses.
  • The study compared fetal renal artery blood flow in 48 fetuses from mothers with PE versus those with uncomplicated pregnancies, using Doppler ultrasound measures.
  • Findings indicated fetuses of mothers with PE had lower renal artery S/D ratios and resistance indices, which may suggest long-term health impacts for these fetuses later in life.

Purpose Describe how Ohio and Massachusetts explored severe maternal morbidity (SMM) data, and used these data for increasing awareness and driving practice changes to reduce maternal morbidity and mortality. Description For 2008-2013, Ohio used de-identified hospital discharge records and International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes to identify delivery hospitalizations. Massachusetts used existing linked data system infrastructure to identify delivery hospitalizations from birth certificates linked to hospital discharge records.

Introduction An important yet understudied component of postpartum type 2 diabetes risk reduction among high risk women is experiences with the healthcare system. Our objective was to describe the healthcare experiences of a diverse, low-income sample of women with prior GDM, including their suggestions for improving care. Methods Focus groups were conducted among African American, Hispanic, and Appalachian women who were diagnosed with GDM within the past 10 years.

Ohio established a Pregnancy-Associated Mortality Review system in 2010 to ensure that all maternal deaths are identified and preventive actions developed. The need for detailed and reliable information to supplement vital statistics data has led to the development of state-based and urban-based maternal death reviews. Although processes vary from state to state, in general, an expert panel is convened to review individual cases and make recommendations for systems change.

Problem: Neutrophil gelatinase-associated lipocalin (NGAL) is expressed in neutrophils and involved in innate immunity by sequestering iron. NGAL's ability to complex with matrix metalloproteinase-9 (MMP-9) and extend its gelatinolytic activity led us to investigate its role in pregnancies complicated by preterm birth (PTB) and intra-amniotic infection/inflammation (IAI).

Method Of Study: We assayed the amniotic fluid (AF) levels of NGAL and MMP-9 in 308 women that had a clinically indicated amniocentesis and a normal pregnancy outcome or PTB.

Introduction: Postpartum screening for glucose intolerance among women with recent histories of gestational diabetes mellitus (GDM) is important for identifying women with continued glucose intolerance after birth, yet screening rates are suboptimal. In a thorough review of the literature, we found no studies of screening practices among certified nurse-midwives (CNMs). The objectives of our study were to estimate the prevalence of postpartum screening for abnormal glucose tolerance and related care by CNMs for women with recent histories of GDM and to identify strategies for improvement.

The use of prescription and over-the-counter medications and dietary supplements are common among women of reproductive age. For medications, little information about the teratogenic risks or safety is available, as pregnant women are traditionally excluded from clinical trials, and premarketing animal studies do not necessarily predict the effects of treatment in human pregnancy. Even less is typically known about the effects of dietary supplements on pregnancy outcomes, as they are not held to the same rigorous safety and efficacy standards as prescription medications.

Women of child-bearing age should achieve and maintain good nutritional status prior to conception to help minimize health risks to both mothers and infants. Many women may not be aware of the importance of preconception nutrition and supplementation or have access to nutrition information. Health care providers should be knowledgeable about preconception/pregnancy-related nutrition and take the initiative to discuss this information during preconception counseling.
