BACKGROUND: SCN8A mutations are rare and cause a phenotypically heterogeneous early onset epilepsy known as early infantile epileptic encephalopathy type 13 (EIEE13, OMIM #614558). There are currently no clear genotype-phenotype correlations to help guide patient counseling and management. PATIENT DESCRIPTION: We describe a patient with EIEE13 (de novo heterozygous pathogenic mutation in SCN8A - p.Ile240Val (ATT>GTT)) who presented prenatally with maternally reported intermittent, rhythmic movements that, when observed on ultrasound, were concerning for fetal seizures...

PURPOSE: Fetal head and somatic growth dynamics differs in fetuses with congenital heart defects (CHD). We longitudinally characterized fetal head and somatic growth in relation to the type of CHD. METHODS: Four hundred eleven exams from isolated CHD were compared with 1,219 controls. Head and somatic growth was assessed using head circumference (HC), brain volume (BrV = 1/6 × π × (HC/π)3)/2), fetal cephalization index (FCI = BrV/[estimated fetal weight]), and growth percentile...

BACKGROUND: Stage I twin-twin transfusion syndrome presents a management dilemma. Intervention may lead to procedure-related complications while expectant management risks deterioration. Insufficient data exist to inform decision-making. OBJECTIVE: The aim of this retrospective observational study was to describe the natural history of stage I twin-twin transfusion syndrome, to assess for predictors of disease behavior, and to compare pregnancy outcomes after intervention at stage I vs expectant management...

OBJECTIVE: To determine the relationship between maternal blood pressures throughout pregnancy and the risk of delivering a small-for-gestational-age (SGA) neonate. METHODS: Women were prospectively enrolled at 9-14 weeks and had serial blood pressure measurements throughout pregnancy. SGA prevalence was compared to maternal blood pressure at enrollment, average blood pressure during each trimester, and blood pressure trends throughout gestation. Blood pressure was categorized as normotension, prehypertension, or hypertension using Joint National Committee on Hypertension-7 (JNC-7) definitions...

The ductus venosus has a central role in the distribution of highly oxygenated umbilical venous blood to the heart. Its waveform is related to the pressure-volume changes in the cardiac atria and it is therefore important in the monitoring of any fetal condition that may affect forward cardiac function. The cardiovascular parameters that can influence forward cardiac function include afterload, myocardial performance and preload. Decreased forward flow during atrial systole (a-wave) is the most sensitive and ubiquitous finding when any of these parameters is affected...

OBJECTIVE: To examine potential correlations between maternal serum placental protein-13 (PP-13) and first trimester maternal and placental factors, and to evaluate the association of this marker with adverse pregnancy outcome. METHODS: Serum samples from prospectively enrolled patients between 11 and 13 weeks and 6 days were analyzed for PP-13 using an ELISA assay. The relationships between maternal serum PP-13 levels and gestational age, maternal age, ethnicity, parity, smoking status, body mass index (BMI), mean arterial blood pressure, uterine and umbilical artery Doppler parameters were examined...

OBJECTIVE: To determine, by expert consensus, a definition for early and late fetal growth restriction (FGR) through a Delphi procedure. METHOD: A Delphi survey was conducted among an international panel of experts on FGR. Panel members were provided with 18 literature-based parameters for defining FGR and were asked to rate the importance of these parameters for the diagnosis of both early and late FGR on a 5-point Likert scale. Parameters were described as solitary parameters (parameters that are sufficient to diagnose FGR, even if all other parameters are normal) and contributory parameters (parameters that require other abnormal parameter(s) to be present for the diagnosis of FGR)...

OBJECTIVE: To compare performance of multimarker algorithm, risk profiles and their sequential application in prediction of preeclampsia and determining potential intervention targets. STUDY DESIGN: Maternal characteristics, ultrasound variables and serum biomarkers were collected prospectively at first trimester. Univariate analysis identified preeclampsia associated variables followed by logistic regression analysis to determine the prediction rule. Combined characteristics of the cardiovascular, metabolic and the personal risk factors were compared to the multimarker algorithm and the sequential application of both methods...

A uniform approach to the diagnosis and management of fetal growth restriction (FGR) consistently produces better outcome, prevention of unanticipated stillbirth, and appropriate timing of delivery. Early-onset and late-onset FGR represent two distinct clinical phenotypes of placental dysfunction. Management challenges in early-onset FGR revolve around prematurity and coexisting maternal hypertensive disease, whereas in late-onset disease failure of diagnosis or surveillance leading to unanticipated stillbirth is the primary issue...

OBJECTIVES: To determine the risk factors for spontaneous preterm delivery (PTD) or preterm prelabor rupture of membranes (PPROM) at < 34 weeks' gestation after fetoscopic laser surgery for twin-twin transfusion syndrome and to identify the optimal threshold for preoperative cervical length (CL) that indicates a high risk for spontaneous PTD. METHODS: This was a secondary analysis of data prospectively collected from 449 patients at three fetal centers. CL measurements were obtained by preoperative transvaginal ultrasound, at a gestational age of 16-26 weeks...

Gestational diabetes mellitus (GDM)-associated fetal and neonatal adverse outcome results from the metabolic milieu projected on the fetus via the placental interface. Therefore, it can be considered to be one of the great obstetrical syndromes. Placentas from GDM pregnancies differ from nondiabetic pregnancies by an increased placental to fetal ratio and by histological findings such as villous fibrinoid necrosis, villous immaturity, chorangiosis, and ischemic changes. While early onset diabetes is more associated with marked structural changes of the placenta, GDM that rises at late gestation is associated more with placental functional changes...

OBJECTIVE: To predict gestational diabetes mellitus (GDM) or normoglycemic status using first trimester maternal characteristics. METHODS: We used data from a prospective cohort study. First trimester maternal characteristics were compared between women with and without GDM. Association of these variables with sugar values at glucose challenge test (GCT) and subsequent GDM was tested to identify key parameters. A predictive algorithm for GDM was developed and receiver operating characteristics (ROC) statistics was used to derive the optimal risk score...
