Monitoring the uterine contraction provides important prognostic information during pregnancy and parturition. The existing methods employed in clinical practice impose a compromise between reliability and invasiveness. A promising technique for uterine contraction monitoring is electrohysterography (EHG). The EHG signal measures the electrical activity(More)
Premature birth is a major cause of mortality and permanent dysfunctions. Several parameters derived from single channel electrohysterographic (EHG) signals have been considered to determine contractions leading to preterm delivery. The results are promising, but improvements are needed. As effective uterine contractions result from a proper action(More)
Electrophysiological measurement of uterine contractions, referred to as electrohysterogram (EHG), is potentially more informative than methods currently used during pregnancy for timely recognition of complications such as preterm labor. Unfortunately, EHG measurement and interpretation remain challenging. Recently, some attention has been dedicated to the(More)
OBJECTIVE To evaluate the relation between breech position at term (>37 weeks of gestation) and low maternal fT4 levels during gestation in women not suffering from overt thyroid dysfunction. DESIGN A prospective cohort study of pregnant women. SETTING Community-based study. POPULATION/SAMPLE At random selected pregnant women of the general(More)
Minimal invasive techniques are rapidly becoming standard surgical techniques for many surgical procedures. To develop the skills necessary to apply these techniques, box trainers and/or inanimate models may be used, but these trainers lack the possibility of inherent objective classification of results. In the past decade, virtual reality (VR) trainers(More)
Multi-electrode electrical measurements on the maternal abdomen may provide a valuable alternative to standard fetal monitoring. Removal of the maternal ECG from these recordings by means of subtracting a weighted linear combination of segments from preceding maternal ECG complexes, results in fetal ECG traces from which the fetal heart rate can be(More)
Fetal monitoring during pregnancy is important to support medical decision making. The fetal electrocardiogram (fECG) is a valuable signal to diagnose fetal well-being. Non-invasive recording of the fECG is performed by positioning electrodes on the maternal abdomen. The signal-to-noise ratio of these recordings is relatively low and the main undesired(More)
UNLABELLED This review aimed to raise awareness of the consequences of suboptimal bonding caused by prematurity. In addition to hypoxia-ischaemia, infection and malnutrition, suboptimal bonding is one of the many unnatural stimuli that preterm infants are exposed to, compromising their physiological development. However, the physiological consequences of(More)
Monitoring the uterine contractions provides important prognostic information during pregnancy and delivery. In particular, the propagation of uterine activity is closely related to the contraction efficiency. In the present study, a propagation analysis of uterine contraction is carried out by simultaneously recording the electrohysterogram (EHG) and the(More)
During pregnancy, analysis of the electrohysterogram (EHG), which measures the uterine electrical activity, can provide a fundamental contribution for the assessment of uterine contractions and the diagnosis of preterm labor. However, several aspects concerning uterine physiology and its link with EHG measurements are still unclear. As a consequence, the(More)
