OBJECTIVE: Ultrasonographic examination is the first-tier test to detect abnormal development of central nervous system (CNS). In optimal conditions, neurosonography can detect all important hallmarks of CNS development. It is, however, not known how the performance of this modality is in a routine setting. We aimed to evaluate the feasibility of neurosonography in a time-limited routine setting. STUDY DESIGN: We have performed a prospective study in which we have included a group of pregnant women carrying a fetus with an isolated congenital heart defect (CHD), and a control group of fetuses without structural anomalies...

More than 290 million people worldwide, and almost 2 million people in the United States, are infected with hepatitis B virus, which can lead to chronic hepatitis B, a vaccine-preventable communicable disease. The prevalence of chronic hepatitis B infection in pregnancy is estimated to be 0.7% to 0.9% in the United States, with >25,000 infants born annually at risk for chronic infection due to perinatal transmission. Given the burden of disease associated with chronic hepatitis B infection, recent national guidance has expanded both the indications for screening for hepatitis B infection and immunity and the indications for vaccination...

IMPORTANCE: Fetal growth restriction (FGR) is a common pregnancy complication and a significant contributor of fetal and neonatal morbidity and mortality, mainly due to the lack of effective screening, prevention, and management policies. OBJECTIVE: The aim of this study was to review and compare the most recently published influential guidelines on the management of pregnancies complicated by FGR. EVIDENCE ACQUISITION: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Society for Maternal-Fetal Medicine, the International Federation of Gynecology and Obstetrics, the International Society of Ultrasound in Obstetrics and Gynecology, the Royal College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada (SOGC), the Perinatal Society of Australia and New Zealand, the Royal College of Physicians of Ireland, the French College of Gynecologists and Obstetricians (FCGO), and the German Society of Gynecology and Obstetrics on FGR was carried out...

Fetal hypoxia can cause damaging consequences on babies' such as stillbirth and cerebral palsy. Cardiotocography (CTG) has been used to detect intrapartum fetal hypoxia during labor. It is a non-invasive machine that measures the fetal heart rate and uterine contractions. Visual CTG suffers inconsistencies in interpretations among clinicians that can delay interventions. Machine learning (ML) showed potential in classifying abnormal CTG, allowing automatic interpretation. In the absence of a gold standard, researchers used various surrogate biomarkers to classify CTG, where some were clinically irrelevant...

Pregnancy predisposes to arrhythmias in females due to physiological changes in the cardiovascular system, enhanced activity of the sympathetic nervous system (SNS), and changes in the endocrine system, regardless of whether there exist cardiovascular diseases before the pregnancy. Tachyarrhythmias may present for the first time or worsen persistently during pregnancy, potentially leading to maternal heart failure and sudden death, as well as some adverse fetal outcomes such as growth restriction, distress, premature birth, and stillbirth...

OBJECTIVE: Fetal growth restriction is a common obstetrical complication that affects up to 10% of pregnancies in the general population and is most commonly due to underlying placental diseases. The purpose of this guideline is to provide summary statements and recommendations to support a clinical framework for effective screening, diagnosis, and management of pregnancies that are either at risk of or affected by fetal growth restriction. TARGET POPULATION: All pregnant patients with a singleton pregnancy...

Background: Postpartum contraceptive use can help prevent short-interval pregnancies, which have been associated with adverse neonatal and maternal health outcomes. Many contraceptive methods are safe for postpartum use, but patients and providers may be confused as to what impact hormonal contraception has on lactation. We performed a scoping review of the most recent U.S.-based guidelines regarding hormonal contraception on lactation to provide synthesis and recommendations to aid providers in counseling their patients...

BACKGROUND: To reduce cesarean delivery rates in nulliparous women, guidelines for diagnosing nonprogressive labor have been developed by the National Institute of Child Health and Human Development, the American College of Obstetricians and Gynecologists, and the Society for Maternal-Fetal Medicine. These are mainly based on data from the Consortium for Safe Labor study. The guidelines have not been tested in a clinical trial, so the efficacy and safety of this new approach is uncertain...

INTRODUCTION: Sepsis is one of the leading causes of maternal morbidity and mortality worldwide and a major public health concern, often associated with delayed diagnosis, suboptimal management, and poor perinatal outcomes. OBJECTIVES: The aim of this study was to review and compare the most recently published influential guidelines on the prevention, diagnosis, and management of this complication during antenatal, intrapartum, and postpartum periods. EVIDENCE ACQUISITION: A descriptive review of guidelines from the Royal College of Obstetricians and Gynaecologists (RCOG), the Society for Maternal-Fetal Medicine (SMFM), the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ), the World Health Organization (WHO), and the Society of Obstetricians and Gynecologists of Canada (SOGC) on maternal and puerperal sepsis was carried out...

OBJECTIVE:  The nomenclature has evolved from low implantation to cesarean scar pregnancy (CSP) and criteria are recommended for identification and management. Management guidelines include pregnancy termination due to life-threatening complications. This article applies ultrasound (US) parameters recommended by the Society for Maternal Fetal Medicine (SMFM) in women who were expectantly managed. STUDY DESIGN:  Pregnancies were identified between March 1, 2013 and December 31, 2020...

This study reviewed the literature regarding the diagnosis, antepartum surveillance, and timing of delivery of pregnancies complicated by intrahepatic cholestasis of pregnancy, comparing the guidelines published by the Society for Maternal-Fetal Medicine in February 2021 and those published by the Royal College of Obstetricians and Gynaecologists in the United Kingdom in June 2022. Several key differences exist in the clinical guidelines between the 2 organizations. With regard to the diagnosis of intrahepatic cholestasis of pregnancy, the Society for Maternal-Fetal Medicine considers any elevation in bile acids above the upper limit of normal in the setting of maternal pruritus diagnostic of intrahepatic cholestasis of pregnancy, whereas the Royal College of Obstetricians and Gynaecologists requires a pregnancy-specific elevated bile acid level of ≥19 mmol/L for diagnosis...

INTRODUCTION: Preeclampsia is a leading cause of pregnancy-related deaths. Up to 60% of maternal deaths associated with preeclampsia may be prevented. Clinical trials have shown that low dose aspirin reduces preeclampsia up to 30% among women at increased risk. Since 2014, multiple professional societies and the United States Preventive Services Task Force have released guidelines on the use of low dose aspirin to reduce the risk of preeclampsia. We aimed to evaluate physician knowledge and practices surrounding low dose aspirin for preeclampsia risk reduction...

INTRODUCTION: The 2021-updated guidelines of the Spanish Society of Neonatology Guidelines have moved the zone of parental discretion to 23 + 0-23 + 6 weeks. The objective of this study was to describe the changes in perinatal management at this gestational age along the last decade and to determine if a more active perinatal management has contributed to improved outcomes. METHODS: Retrospective analysis of prospectively collected data from the 23-week infants included in the Spanish SEN 1500 neonatal network during the period 2010-2019...

Preterm birth remains the leading cause of morbidity and mortality among non-anomalous neonates in the United States. Unfortunately, rates of preterm birth remain high despite current medical interventions such as progestogen supplementation and cerclage placement. Case management, which encompasses coordinated care aimed at providing a more comprehensive and supportive environment, is a key component in improving health and reducing costs in other areas of medicine but largely has not made its way into the lexicon and practice of obstetric care...

PURPOSE: Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse fetal and neonatal outcome. Evidence for improvement by obstetric management is sparse. Common international guidelines recommend induction of labor before term, however, they differ in recommendations of monitoring the disease and time point of active management. So far, an official guideline for treatment and management of ICP in Germany does not exist. This study aims to compile common practice and policy in obstetric management of ICP in German maternity units...

BACKGROUND: Intrahepatic cholestasis of pregnancy is associated with a significant risk of stillbirth, which contributes to variation in clinical management. Recent Society for Maternal-Fetal Medicine guidance recommends delivery at 36 weeks of gestation for patients with serum bile acid levels of >100 μmol/L, consideration for delivery between 36 and 39 weeks of gestation stratified by bile acid level, and against preterm delivery for those with clinical features of cholestasis without bile acid elevation...

IMPORTANCE: The risk of venous thromboembolism (VTE) increases during pregnancy and the postpartum period. Deep vein thrombosis is the most common VTE during pregnancy, but pulmonary embolism is typically of greater concern as it contributes to far higher morbidity and mortality. Diagnosis and treatment of VTE during pregnancy differ substantially from the general nonpregnant population. OBJECTIVE: This review describes the epidemiology, risk factors, clinical presentation, diagnosis, and treatment of VTE during pregnancy and the postpartum period...

PURPOSE: To objectively evaluate the methodological quality and clinical heterogeneity robustness of the published clinical practice guidelines (CPGs) on the management of trauma in pregnancy. MATERIALS AND METHODS: Pubmed, Google Scholar, UpToDate, and Scopus Database were searched. The risk of bias and quality assessment of the included CPGs were performed using "The Appraisal Of Guidelines for Research and Evaluation (AGREE II)" tool. The following points relating to the management of trauma during pregnancy were addressed: quality of evidence assessment, classification of recommendations, main causes of trauma in pregnancy, importance of correct use of seat belts, ultrasound scans and/or pregnancy test in every female of reproductive age, description of physiological changes in pregnancy, classification in primary and secondary survey, primary survey based on ABCD Approach, fetus viable based on the weeks, radiographic studies for maternal evaluation, duration of fetal monitoring, use of anti-D immunoglobulin in rhesus-D-negative pregnant trauma patients, description of dose of RhD-Ig, the way to define gestational age if it was undetermined, descriptions of obstetrical complications, use of tetanus vaccination, and timing to perimortem cesarean section (CS)...

For more than a century, substantial racial and ethnic inequities in perinatal health outcomes have persisted despite technical clinical advances and changes in public health practice that lowered the overall incidence of morbidity. Race is a social construct and not an inherent biologic or genetic reality; therefore, racial differences in health outcomes represent the consequences of structural racism or the inequitable distribution of opportunities for health along racialized lines. Clinicians and scientists in obstetrics and gynecology have a responsibility to work to eliminate health inequities for Black, Brown, and Indigenous birthing people, and fulfilling this responsibility requires actionable evidence from high-quality research...

OBJECTIVE: This guideline was developed by maternity care providers from obstetrics and internal medicine. It reviews the diagnosis, evaluation, and management of the hypertensive disorders of pregnancy (HDPs), the prediction and prevention of preeclampsia, and the postpartum care of women with a previous HDP. TARGET POPULATION: Pregnant women. BENEFITS, HARMS, AND COSTS: Implementation of the recommendations in these guidelines may reduce the incidence of the HDPs, particularly preeclampsia, and associated adverse outcomes...
