Fetal Heart Monitoring, Nursing Surveillance, and Cesarean Birth
… two-fold: (1) to examine nursing assessment of fetal heart rate (FHR) tracing and their interventions (nursing surveillance) in response to identification of an FHR tracing consistent with category II pattern and (2) to identify whether nursing surveillance and frequency of category II patterns …

Categorizing Fetal Heart Rate Variability with and without Visual Aids
… clinicians and novices to correctly categorize fetal heart rate (FHR) variability with and without the use of exemplars. Clinicians and undergraduate students were asked to inspect FHR images and determine into which of four categories they belonged. Each participant took part in three …

The impact of suboptimal maternal diet on fetal heart development: Identifying targets for intervention
… metabolic, and contractile profiles within the fetal heart. Across studies, it was highlighted that high-risk cardiac phenotypes are present even with normal fetal body weight, challenging the traditional view that birth weight is a predictor of cardiovascular disease (CVD) risk. Mechanisms …

Characterizing the effects of in utero exposure to valproic acid on murine fetal heart development
… been associated with a higher risk of congenital heart defects. In spite of this, expectant mothers are advised to continue taking it throughout pregnancy to prevent seizures. One proposed mechanism of VPA-initiated teratogenicity is the inhibition of histone deacetylase (HDAC), which is involved …

Comparability of an innovative Doppler ultrasound fetal heart rate monitor to a pinard fetal stethoscope using cardiotocography as a standard to assess the fetal heart rate in singleton pregnancies during labour at Mowbray Maternity Hospital
… often preventable with appropriate maternal and fetal monitoring in labour. However, this remains a challenge in under-resourced settings, due to difficulties that accompany the use of a Pinard Fetal Stethoscope (PFS) which include user-dependence and lack of evidence based standardisation in …

A randomised comparison of bolus phenylephrine and ephedrine for the management of spinal hypotension in patients with severe preeclampsia and a non-reassuring fetal heart rate trace
… spinal hypotension is associated with increased fetal acidosis compared with phenylephrine. This has not been investigated prospectively in severe preeclampsia. Methods: Patients with severe preeclampsia requiring caesarean delivery for a non- reassuring fetal heart tracing were randomised to …

Improved Late-gestation Cardiac Morphology in Fetuses of Diabetic Mothers After Maternal Immune Stimulation: Potential Role of Dysregulated Apoptosis
… tube and cardiac defects predominate among the fetal malformations induced by hyperglycemia. Non-specific maternal immune stimulation is protective in mice against birth malformations caused by chemical or physical teratogens, or by maternal diabetes mellitus. Insulin dependent diabetes was …

i-MOM: Improving Maternal-fetal Outcome Monitoring
… in the United States is use of an electronic fetal monitor (EFM), which is employed to predict and eliminate hypoxic injury during birth. However, since inception of the EFM in the 1960s, incidence of hypoxic injury has remained nearly the same. Riddled with conflicting and confusing data, the …

Prenatal Cocaine Exposure and Cardiac Programming
… environment and an increased risk of ischemia heart disease in later adult life. Cocaine abuse during pregnancy has been shown to cause abnormities in the heart during fetal and postnatal development, but mechanisms underlying the detrimental effects of cocaine on the developing heart are not …

Maternal Cardiac Autonomic Function and Fetal Behaviour in Hypertensive and Obese Pregnancies
… is associated with placental insufficiency and fetal growth restriction, whereas obesity in pregnancy is associated with placental inflammation and macrosomia. Fetal growth restriction is associated with an increased risk for language deficits at 2-5 years of age. However, maternal cardiac …

Exploring the sex-specific programming of cardiovascular disease by maternal obesity and assessing potential interventions to the mother
… obesity also results in maternal, placental, and fetal oxidative stress, antioxidant interventions to the mother may be another effective treatment. Human and mouse models of maternal obesity have shown that antioxidant supplementation can prevent an adverse offspring cardiometabolic phenotype. …

Source characterization using linear transformations of multichannel biomagnetic recordings
… the brain, via magnetoencephalography (MEG), and heart, via magnetocardiography (MCG). Dense-array biomagnetometers have been recently designed for the investigation of the neurophysiological development of the fetus in utero. Fetal MCG offers accurate recordings of the fetal cardiac activity that …

‘SHE CAME THROUGH ME’: Situating Birth Stories and Women’s Embodied Wisdom in Folkloristics
… experience. Does the woman have an epidural? A fetal heart rate monitor (internal or external)? An IV? What is she feeling? Did she and her partner take childbirth classes (if yes, what style)? The doctor is usually only present for the pushing stage or emergencies. The birth world is full of …

Prenatal influences on fetal neurodevelopment: Can a person-centered approach help parse the complexity of maternal vulnerability and protective features and detect early alterations to fetal neurodevelopment trajectories related to prenatal distress?
… developmental profile, yet there is little fetal evidence of this putative in utero process. Moreover, the biological transmission for these maternal effects remains uncertain. To advance our understanding of developmental pathways of early transmission of risk we must identify more …

The influence of birth site on short-term outcomes of encephalopathic newborn infants treated with therapeutic hypothermia at Groote Schuur Hospital, Cape Town, South Africa
… Pregnancy complications and abnormal intrapartum fetal heart rates occurred more frequently in inborn infants (65.2 % vs. 24.2 %, p=0.0001 and 47.8% vs. 20.6%, p =0.03 respectively). More outborn babies died or had an abnormal aEEG at 48 hours (32 % vs. 22 %, p=0.556) and fewer outborn babies …

Clinical and ultrasonic estimation of fetal weight
… it is useful to make an accurate assessment of fetal weight prior to delivery. A foreknowledge of the mass of the fetus can influence management in circumstances complicated by, for example, a previous caesarean section, a breech presentation, a compromised fetus of borderline viability and a …

Algorithms and systems for home telemonitoring in biomedical applications
… telemonitoring application considered is the fetal electrocardiography. Non-invasive fetal electrocardiography is the recording of the fetal heart electrical activity using electrodes placed on the maternal abdomen. It can provide important diagnostic parameters, such as the beat-to-beat heart …

Algorithm and Hardware Co-optimization for Image Segmentation in Wearable Ultrasound Devices: Continuous Bladder Monitoring

This technology, together with advances in compact ultrasound patches, will enable real-time tissue monitoring on the edge, thereby not only maintaining health data privacy, but also improving both point-of-care …

Reconsidering Evidence: Evidence-based Practice and Maternity Care in Canada
… in favour of auscultation rather than electronic fetal heart monitoring. My findings reveal patterns of over application, for example, when research about post-term pregnancy is used as a rationale for induction of labour earlier than the findings justify. Informants described under interpretation …

Effects of Long-Term, High-Altitude Hypoxemia on Fetal Ovine Coronary Arteries
… high-altitude hypoxemia on the contractility of fetal coronary vessels, namely the left circumflex, left anterior descending, and right coronary arteries. We have found that in response to chronic hypoxia, isolated fetal ovine coronary arteries exhibit attenuated contractile responsiveness to …
