OBJECTIVE Intrauterine growth restriction (IUGR) is characterized by chronic nutrient deprivation and hypoxemia that alters the autonomous nervous system regulation of fetal heart rate variability (fHRV). Phase-rectified signal averaging (PRSA) is a new algorithm capable to identify periodic and quasi-periodic patterns of HR, and which is used to quantify(More)
OBJECTIVE Phase rectified signal averaging (PRSA) is a new method of fetal heart rate variability (fHRV) analysis that quantifies the average acceleration (AC) and deceleration capacity (DC) of the heart. The aim of this study was to evaluate AC and DC of fHR [recorded by trans-abdominal fetal electrocardiogram (ta-fECG)] in relation to Doppler velocimetry(More)
BACKGROUND Fetal heart rate (FHR) variability is an indirect index of fetal autonomic nervous system (ANS) integrity. FHR variability analysis in labor fails to detect early hypoxia and acidemia. Phase-rectified signal averaging (PRSA) is a new method of complex biological signals analysis that is more resistant to non-stationarities, signal loss and(More)
Fetal monitoring during labour currently fails to accurately detect acidemia. We developed a method to assess the multidimensional properties of fetal heart rate variability (fHRV) from trans-abdominal fetal electrocardiogram (fECG) during labour. We aimed to assess this novel bioinformatics approach for correlation between fHRV and neonatal pH or base(More)
AIM The aim was to study prevalence of menstrual symptoms and their presenting patterns, and to assess nutrition and behaviours correlates. METHODS The study enrolled 108 women, who were prospectively assessed for menstrual symptoms; a 212 items questionnaire about lifestyle and nutrition was administered. Diagnosis and intensity of symptoms were(More)
Fetal heart rate (FHR) sampling rate used on the bedside is equal or less than 4 Hz. Current FHR analysis methods fail to detect incipient fetal acidemia. In a fetal sheep model of human labour we showed that FHR sampling rates near 1000 Hz are needed to detect fetal acidemia. Trans-abdominal fetal ECG (t-a fECG) sampling FHR at 900 Hz combined with a(More)
OBJECTIVE To compare intra-partum performance of trans-abdominal electrocardiogram with Doppler telemetry. METHODS In this prospective longitudinal study, simultaneous monitoring with trans-abdominal ECG and Doppler telemetry was performed in 41 uncomplicated term singleton pregnancies during labour. RESULTS The overall success rate for FHR monitoring(More)
BACKGROUND AND AIM Alternative therapies based on homeopathy can be effective in improving reproductive performance in intensive pig breeding. In this study, the effect of a homeopathic complex on reproductive performance of sows under intensive farming has been investigated. MATERIAL AND METHODS Over period of three years, 186 sows were recruited from a(More)
UNLABELLED Couplings between uterine contractions (UC) and fetal heart rate (fHR) provide important information on fetal condition during labor. At present, couplings between UC and fHR are assessed by visual analysis and interpretation of cardiotocography. The application of computerized approaches is restricted due to the non-stationarity of the signal,(More)
