Continuous glucose monitoring in pregnancies with type 1 diabetes: small increases in time-in-range improve maternal and perinatal outcomes.

Background: Continuous glucose monitors provide detailed information regarding glycemic control in pregnant patients with type 1 diabetes. Little data have been published examining the association between continuous glucose monitor parameters and perinatal outcomes among gravidas with type 1 diabetes using continuous glucose monitors.

Objective: This study aimed to examine the association between perinatal outcomes and time-in-range as assessed by continuous glucose monitors used in pregnant individuals with type 1 diabetes.

Discovery and verification of extracellular microRNA biomarkers for diagnostic and prognostic assessment of preeclampsia at triage.

We report on the identification of extracellular miRNA (ex-miRNA) biomarkers for early diagnosis and prognosis of preeclampsia (PE). Small RNA sequencing of maternal serum prospectively collected from participants undergoing evaluation for suspected PE revealed distinct patterns of ex-miRNA expression among different categories of hypertensive disorders in pregnancy. Applying an iterative machine learning method identified three bivariate miRNA biomarkers (, , and ) that, when applied serially, distinguished between PE cases of different severity and differentiated cases from controls with a sensitivity of 93%, specificity of 79%, positive predictive value (PPV) of 55%, and negative predictive value (NPV) of 89%.

Metformin Plus Insulin for Preexisting Diabetes or Gestational Diabetes in Early Pregnancy: The MOMPOD Randomized Clinical Trial.

Importance: Insulin is recommended for pregnant persons with preexisting type 2 diabetes or diabetes diagnosed early in pregnancy. The addition of metformin to insulin may improve neonatal outcomes.

Objective: To estimate the effect of metformin added to insulin for preexisting type 2 or diabetes diagnosed early in pregnancy on a composite adverse neonatal outcome.

Dicavitary twin pregnancy in patient with bicornuate bicollis uterine anomaly.

Key Clinical Message: Twin pregnancies in uterine didelphys and uterus bicornuate bicollis represent dicavitary twin pregnancies that can be managed using similar principles. Consideration must be given to delivery planning including mode of delivery and uterine incision.

Abstract: Dicavitary twin pregnancies present unique challenges for obstetric management.

Associations Between Preconception Glycemia and Preterm Birth: The Potential Role of Health Care Access and Utilization.

Preconception diabetes is strongly associated with adverse birth outcomes. Less is known about the effects of elevated glycemia at levels below clinical cutoffs for diabetes. In this study, we estimated associations between preconception diabetes, prediabetes, and hemoglobin A1c (HbA1c) on the risk of preterm birth, and evaluated whether associations were modified by access to or utilization of health care services.

Early screening for gestational diabetes mellitus: a meta-analysis of randomized controlled trials.

Objective: Current evidence is conflicting on whether early screening and treatment for gestational diabetes mellitus improve pregnancy outcomes. Thus, this systematic review and meta-analysis of randomized controlled trials aimed to assess the rate of adverse pregnancy outcomes among participants with early screening and treatment for gestational diabetes mellitus vs those with routine care.

Data Sources: A systematic review of the literature was conducted using MEDLINE, Scopus, ClinicalTrials.

Chronic hypertension and risk of preterm delivery: National Longitudinal Study of Adolescents to Adult Health.

Background: Chronic hypertension during pregnancy is associated with increased risk of adverse birth outcomes. In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered thresholds to classify hypertension in non-pregnant adults to SBP ≥ 130 mmHg and DBP ≥ 80 mmHg (ie stage I hypertension), resulting in an additional 4.5-million reproductive-aged women meeting criteria for hypertension.

Placenta Accreta Spectrum Treatment With Intraoperative Multivessel Embolization: the PASTIME protocol.

Background: Multidisciplinary care of placenta accreta spectrum cases improves pregnancy outcomes, but the specific components of such a multidisciplinary collaboration varies between institutions. As experience with placenta accreta spectrum increases, it is crucial to assess new surgical techniques and protocols to help improve maternal outcomes and to advocate for hospital resources.

Objective: This study aimed to assess a novel multidisciplinary protocol for the treatment of placenta accreta spectrum that comprises cesarean delivery, multivessel uterine embolization, and hysterectomy in a single procedure within a hybrid operative suite.

Obstetrical Unit Response to the COVID-19 Pandemic: OUR Study.

Objective: This study aimed to describe the response of labor and delivery (L&D) units in the United States to the novel coronavirus disease 2019 (COVID-19) pandemic and determine how institutional characteristics and regional disease prevalence affect viral testing and personal protective equipment (PPE).

Study Design: A cross-sectional survey was distributed electronically through the Society for Maternal-Fetal Medicine e-mail database ( = 584 distinct practices) and social media between April 14 and 23, 2020. Participants were recruited through "snowballing.

Discovery and Verification of Extracellular miRNA Biomarkers for Non-invasive Prediction of Pre-eclampsia in Asymptomatic Women.

Development of effective prevention and treatment strategies for pre-eclampsia is limited by the lack of accurate methods for identification of at-risk pregnancies. We performed small RNA sequencing (RNA-seq) of maternal serum extracellular RNAs (exRNAs) to discover and verify microRNAs (miRNAs) differentially expressed in patients who later developed pre-eclampsia. Sera collected from 73 pre-eclampsia cases and 139 controls between 17 and 28 weeks gestational age (GA), divided into separate discovery and verification cohorts, are analyzed by small RNA-seq.

Ultrasound and Magnetic Resonance Imaging of Agenesis of the Corpus Callosum in Fetuses: Frontal Horns and Cavum Septi Pellucidi Are Clues to Earlier Diagnosis.

Objectives: We hypothesized that: (1) fetal frontal horn (FH) morphology and their proximity to the cavum septi pellucidi (CSP) can assist in suspecting complete agenesis of the corpus callosum (cACC) and partial agenesis of the corpus callosum (pACC) earlier than known indirect ultrasound (US) findings; (2) FHs assist in differentiating a true CSP from a pseudocavum; and (3) magnetic resonance imaging (MRI) is useful in learning FH morphology and pseudocavum etiology.

Methods: Thirty-two patients with cACC and 9 with pACC were identified on an Institutional Review Board-approved retrospective review. Of the 41 cases, 40 had prenatal US, and 21 had prenatal MRI; 17 had follow-up neonatal US, and 14 had follow-up neonatal MRI.
