OBJECTIVE: To evaluate whether intrapartum fetal monitoring with computer analysis and real-time alerts decreases the rate of newborn metabolic acidosis or obstetric intervention when compared with visual analysis. METHODS: A randomized clinical trial carried out in five hospitals in the United Kingdom evaluated women with singleton, vertex fetuses of 36 weeks of gestation or greater during labor. Continuous central fetal monitoring by computer analysis and online alerts (experimental arm) was compared with visual analysis (control arm)...

BACKGROUND: Brain injury leading to a persistent vegetative state during pregnancy involves difficult medical and ethical decisions. CASE: A 21-year-old multigravid woman entered a persistent vegetative state at 20 1/7 weeks of gestation after cardiac arrest with postanoxic brain injury from a suspected drug overdose. The clinical disciplines responsible for her case formed a collaborative care plan involving ventilator, nutrition, and medication support of the mother and regular fetal monitoring and ultrasound testing...

BACKGROUND: Previous event-related potential (ERP) studies of response inhibition in children with fetal alcohol spectrum disorder (FASD) have used a visual Go/NoGo task to study the impact of prenatal alcohol exposure on response inhibition. No studies exist using auditory versions of the task; thus, it is unclear how the deficits observed in visual tasks translate into the auditory domain. METHODS: This study examined ERPs using an auditory Go/NoGo paradigm in a sample of 35 school-age children-18 with heavy prenatal alcohol exposure and 17 normally developing controls...

Vitamin A regulates many essential mammalian biological processes, including embryonic development. β-carotene is the main source of vitamin A in the human diet. Once ingested, it is packaged into lipoproteins, predominantly low-density lipoproteins (LDL), and transported to different sites within the body, including the liver and developing tissues, where it can either be stored or metabolized to retinoids (vitamin A and its derivatives). The molecular mechanisms of β-carotene uptake by the liver or developing tissues remain elusive...

OBJECTIVES: Mitochondrial oxidative phosphorylation is the key energy source for placental functions and fetal growth. The purpose of this study was to investigate the function of placenta in high risk pregnancies by measuring mitochondrial respiratory chain complex (RCC) activities, and to evaluate the correlation between double test risk ratio and RCC activities. METHODS: The placenta samples were collected from 50 pregnant women. The controls consisted of 20 normal uncomplicated pregnancies and the study group (n = 30) consisted of preeclampsia (PE), intrauterin growth restriction (IUGR), advanced maternal age (AMA), twins and preterm deliveries...

: A comprehensive developmental timeline of activity in the mouse cortex in vivo is lacking. Understanding the activity changes that accompany synapse and circuit formation is important to understand the mechanisms by which activity molds circuits and would help to identify critical checkpoints for normal development. To identify key principles of cortical activity maturation, we systematically tracked spontaneous and sensory-evoked activity with extracellular recordings of primary visual cortex (V1) in nonanesthetized mice...

Monitoring the fetal cardiac activity during pregnancy is of crucial importance for evaluating fetus health. However, there is a lack of automatic and reliable methods for Fetal ECG (FECG) monitoring that can perform this elaboration in real-time. In this paper, we present a hardware architecture, implemented on the Altera Stratix V FPGA, capable of separating the FECG from the maternal ECG and to correctly identify it. We evaluated our system using both synthetic and real tracks acquired from patients beyond the 20th pregnancy week...

Phase rectified signal averaging (PRSA) is increasingly used for fetal heart rate (FHR) monitoring, both with traces acquired with external Doppler cardiotocography (D-FHR), and with transabdominal fetal electrocardiography (ta-FHR). However, it is unclear to what extend the acquisition method influences the PRSA analysis, whether results from using one acquisition method are comparable to those based on FHR acquired by the other method, and if not, which should be the preferred method. To address these questions, we applied PRSA analysis to 28 antepartum synchronous recordings of the FHR using simultaneously D-FHR and ta-FHR...

Among women with diabetes, the worst pregnancy outcome is seen in the subgroup of women with diabetic nephropathy. Development of severe preeclampsia that leads to early preterm delivery is frequent. Predictors and pathophysiological mechanisms for the development of preeclampsia among women with diabetes and observational studies that support antihypertension treatment for pregnant women with microalbuminuria or diabetic nephropathy preventing preeclampsia and early preterm delivery are presented here. Obtaining and maintaining strict glycemic control before and during pregnancy is paramount to prevent preterm delivery...

BACKGROUND: Daytime sleepiness is a frequent complaint in women during pregnancy. It has also been linked to negative obstetric consequences. Although high prevalence of excessive daytime sleepiness throughout pregnancy is well-documented, neither the causes of persistent daytime sleepiness nor new-onset daytime sleepiness during pregnancy have been investigated. Identifying predictive factors may play an important role in the management of daytime sleepiness in pregnant women and improve prenatal care and maternal-fetal outcomes...

Progesterone (P4) is a requirement for pregnancy development. Previous reports observed a maximal value of serum P4 concentration on 21 days after the first mating after which it slowly declines throughout the rest of pregnancy. Ultrasound examination should be performed to ensure that pregnancy interruption is complete. Limited information is available on the ultrasonic appearance of conceptuses during pregnancy termination in cats The objective was to study serum P4 concentration and ultrasonographic changes during aglepristone (ALI) or cloprostenol (CLO) treatment and to evaluate the fertility after treatment...

Helena H L Lee, Annisa S L Mak, C F Poon, K Y Leung
A noninvasive approach by serial ultrasound examination at 12-15, 18, and 30 weeks of gestation can be used to exclude homozygous α(0)-thalassemia-induced fetal anemia. At 12-15 weeks of gestation, the predictive values for the fetal cardio-thoracic ratio were better than that for the placental thickness. At 16-20 weeks of gestation, measuring middle cerebral artery peak systolic velocity is associated with a low false-positive rate. However, the false-positive rate of this noninvasive approach can be about 3%, requiring an invasive test to confirm the diagnosis...

AIMS: Prenatal myelomeningocele (MMC) repair has been proven to significantly reduce the need for hydrocephalus shunting and improve lower-extremity motor outcomes. The aim of this study was to evaluate the effect of prenatal MMC repair on the urological outcome. METHODS: All patients who underwent fetal MMC repair at our institution are followed prospectively. Assessments include medical history, renal and bladder ultrasound, voiding cystourethrogram and urodynamic study, need for clean intermittent catheterization (CIC) and anticholinergics, and the occurrence of urinary tract infections (UTI)...

Neuromuscular disorders such as Pompe disease (glycogen storage disease, type II), result in early and potentially irreversible cellular damage with a very limited opportunity for intervention in the newborn period. Pompe disease is due to deficiency in acid α-glucosidase (GAA) leading to lysosomal accumulation of glycogen in all cell types, abnormal myofibrillogenesis, respiratory insufficiency, neurological deficits, and reduced contractile function in striated muscle. Previous studies have shown that fetal delivery of recombinant adeno-associated virus (rAAV) encoding GAA to the peritoneal cavity of Gaa-/- mice resulted in high-level transduction of the diaphragm...

The Wireless Medical Telemetry Service (WMTS) was established in 1999 by the Federal Communications Commission (FCC) to protect the use of licensed medical telemetry for physiological and fetal monitoring. The WMTS space has three frequency bands: 608-614 MHz (over-the-air [OTA] television channel 37), 1,395-1,400 MHz, and 1,427-1,432 MHz. This article addresses the recent FCC rule affecting the OTA channel 37 WMTS band. We also will address the potential impact on WMTS use in the hospital, the potential risks, and what hospitals need to do to mitigate those risks...

OBJECTIVE: In the TRUFFLE study on outcome of early fetal growth restriction women were allocated to three timing of delivery plans according to antenatal monitoring strategies based on reduced computerized cardiotocographic heart rate short term variation (c-CTG STV) , early Ductus Venosus (DV p95) or late DV (DV noA) changes. However, many infants were per protocol delivered because of 'safety net' criteria, or for maternal indications, or 'other fetal indications' or after 32 weeks of gestation when the protocol was not applied anymore...

OBJECTIVE: Fetal growth restriction is a powerful determinant of poor perinatal outcomes. Our previous work in pregnancies at high risk for the development of hypertension found that early in pregnancy maternal haemodynamics show impaired cardiovascular adaptation in gestations destined to deliver growth-restricted infants. In this study, we serially monitored maternal haemodynamics from the first through to the third trimester in a similar high-risk cohort, in order to determine if, in pregnancies complicated by growth-restriction, these distinct haemodynamic profiles found at presentation persisted throughout pregnancy...
