BACKGROUND: The aim of this guideline is to provide updated recommendations for Canadian genetic counsellors, medical geneticists, maternal fetal medicine specialists, clinical laboratory geneticists and other practitioners regarding the use of chromosomal microarray analysis (CMA) for prenatal diagnosis. This guideline replaces the 2011 Society of Obstetricians and Gynaecologists of Canada (SOGC)-Canadian College of Medical Geneticists (CCMG) Joint Technical Update. METHODS: A multidisciplinary group consisting of medical geneticists, genetic counsellors, maternal fetal medicine specialists and clinical laboratory geneticists was assembled to review existing literature and guidelines for use of CMA in prenatal care and to make recommendations relevant to the Canadian context...

BACKGROUND: Obesity in pregnancy has become one of the most important challenges in obstetrical care given its prevalence and potential adverse impact on both mother and fetus. The primary objective of this descriptive review is to identify common themes and distinctions within the current recommendations for maternal obesity in the most updated version of four published national guidelines. METHODS: We reviewed the following guidelines for obesity in pregnancy: American College of Obstetricians and Gynecologists (ACOG) 2015, Royal Australian and New Zealand College of Obstetricians and Gynecologists (RANZCOG) 2013, Royal College of Obstetrics and Gynecology (RCOG) 2010, and Society of Obstetrics and Gynecologists of Canada (SOGC) 2010...

BACKGROUND: Cell-free DNA (cfDNA) screening has recently acquired tremendous attention, promising patients and healthcare providers a more accurate prenatal screen for aneuploidy than other current screening modalities. It is unclear how much knowledge regarding cfDNA screening obstetrical providers possess which has important implications for the quality and content of the informed consent patients receive. METHODS: A survey was designed to assess obstetrical provider knowledge and attitudes towards cfDNA screening and distributed online through the Society of Obstetricians & Gynecologists of Canada (SOGC)...

The Society for Maternal-Fetal Medicine endorses an algorithm for estimating the probability of successful vaginal birth for women undergoing trial of labor after cesarean (TOLAC). The algorithm is available online in the form of an easy-to-use calculator. This calculator has significant limitations that are easily overlooked by women and providers alike. The calculator has much greater positive than negative predictive power, and it cannot predict unsuccessful TOLAC or uterine rupture. Furthermore, the calculator cannot predict rare catastrophes, such as unplanned hysterectomy, permanent injury, or death...

Authors of policy statements from the American College of Obstetrics and Gynecology and from the Society for Maternal-Fetal Medicine do not acknowledge the potential for their clinical income to influence their opinions, or the positions of the societies they represent. These policy statements were published in Obstetrics and Gynecology and the American Journal of Obstetrics and Gynecology, again, without acknowledgement of the potential for conflict of interest. The case of non-invasive prenatal testing, which has threatened the role of maternal-fetal medicine in the practice of prenatal screening and diagnosis, and has significantly reduced the demand for invasive prenatal diagnosis, illustrates the importance of identifying this potential conflict...

OBJECTIVE: The American College of Obstetricians and Gynecologists (ACOG) and Society for Maternal-Fetal Medicine (SMFM) recommend chromosomal microarray analysis (CMA) for prenatal diagnosis in cases with one or more fetal structural abnormalities. For patients who elect prenatal diagnosis and have a structurally normal fetus, either microarray or karyotype is recommended. This study evaluates the frequency of clinically significant chromosomal abnormalities (CSCA) that would have been missed if all patients offered the choice between CMA and karyotyping chose karyotyping...

BACKGROUND: The dramatic rise in cesarean delivery (CD) rates worldwide in recent decades, without evidence of a concomitant decrease in cerebral palsy rates, has raised concerns about its potential negative consequences for maternal and infant health. In 2014, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine jointly published an Obstetric Care Consensus for safe prevention of the primary cesarean delivery. OBJECTIVE: We sought to assess whether modification of our protocol to implement these recommendations helped to decrease our primary CD rate safely...

Perinatal regionalization, or risk-appropriate care, is an approach that classifies facilities based on capabilities to ensure women and infants receive care at a facility that aligns with their risk. The CDC designed the Levels of Care Assessment Tool (LOCATe) to assist jurisdictions working in risk-appropriate care in assessing a facility's level of maternal and neonatal care aligned with the most current American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) and American Academy of Pediatrics (AAP) guidelines...

PURPOSE: Ultrafast single-shot T2 -weighted images are common practice in fetal MR exams. However, there is limited experience with fetal T1 -weighted acquisitions. This study aims at establishing a robust framework that allows fetal T1 -weighted scans to be routinely acquired in utero at 3T. METHODS: A 2D gradient echo sequence with an adiabatic inversion was optimized to be robust to fetal motion and maternal breathing optimizing grey/white matter contrast at the same time...

Racial and ethnic disparities in maternal morbidity and mortality rates are an important public health problem in the United States. Because racial and ethnic minorities are expected to comprise more than one-half of the US population by 2050, this issue needs to be addressed urgently. Research suggests that the drivers of health disparities occur at 3 levels: patient, provider, and system. Although we have recognized this issue and identified elements that contribute to it, knowledge must be converted into action to address it...

Implementation of clinical practice guidelines may moderate health care costs, improve care, reduce medicolegal liability, and provide a uniformity in care allowing meaningful investigation of treatments and outcomes. However, new guidelines are often uncritically embraced by clinicians, risk management organizations, insurance companies, and the courts as the standard of care. Adoption of incompletely vetted recommendations can lead to patient harm. Recent recommendations made by the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine for assessment and management of labor provide an example of well-intended guidelines adopted uncritically...

OBJECTIVE: We sought to determine if hospital delivery volume was associated with a patient's risk for cesarean delivery in low-risk women. STUDY DESIGN: This study retrospectively examines a cohort of 1 657 495 deliveries identified in the 2013 Nationwide Readmissions Database. Hospitals were stratified by delivery volume quartiles. Low-risk patients were identified using the Society for Maternal-Fetal Medicine definition (n=845 056). A multivariable logistic regression accounting for hospital-level clustering was constructed to assess the factors affecting a patient's odds for cesarean delivery...

PURPOSE: Fetal functional MRI studies using conventional 2-dimensional single-shot echo-planar imaging sequences may require discarding a large data fraction as a result of fetal and maternal motion. Increasing the temporal resolution using echo volumar imaging (EVI) could provide an effective alternative strategy. Echo volumar imaging was combined with inner volume (IV) imaging (IVEVI) to locally excite the fetal brain and acquire full 3-dimensional images, fast enough to freeze most fetal head motion...

Third-trimester bleeding is a common complication arising from a variety of etiologies, some of which may initially present in the late preterm period. Previous management recommendations have not been specific to this gestational age window, which carries a potentially lower threshold for delivery. The purpose of this document is to provide guidance on management of late preterm (34 0/7-36 6/7 weeks of gestation) vaginal bleeding. The following are Society for Maternal-Fetal Medicine recommendations: (1) we recommend delivery at 36-37 6/7 weeks of gestation for stable women with placenta previa without bleeding or other obstetric complications, such as preeclampsia or fetal growth restriction (Grade 1B); (2) we do not recommend routine cervical length screening for women with placenta previa in the late preterm period because of a lack of data on an appropriate management strategy (Grade 2C); (3) we recommend a planned delivery between 34 and 37 weeks of gestation for stable women with placenta accreta (Grade 1C); (4) we recommend delivery between 34 and 37 weeks of gestation for stable women with vasa previa (Grade 1C); (5) we recommend that in women with active hemorrhage in the late preterm period, delivery should not be delayed for the purpose of administering antenatal corticosteroids (Grade 1B); (6) we recommend that fetal lung maturity testing should not be used to guide management in the late preterm period when an indication for delivery is present (Grade 1B); and (7) we recommend that antenatal corticosteroids should be administered to women who are eligible and are managed expectantly if delivery is likely within 7 days, the gestational age is between 34 0/7 and 36 6/7 weeks of gestation, and antenatal corticosteroids has not previously been administered (Grade 1A)...

Importance: The rapid development of prenatal genetic testing and screening tools and choices constantly challenges clinicians to stay up to date on current best practice. Objective: We sought to review, compare, and summarize recent national society guidelines on prepregnancy genetic screening and prenatal diagnosis for aneuploidy with a focus on changes and additions to previous guidelines. Evidence Acquisition: We performed a descriptive review of 8 recently published (2016-2017) national guidelines and updates on prenatal genetic screening and testing including American Congress of Obstetricians and Gynecologists committee opinions and practice bulletins, Society for Maternal-Fetal Medicine consult series publications, and an American College of Medical Genetics and Genomics position statement...
