Summary: The study found that the fetal head station at the diagnosis of the second stage of labor is significantly associated with the duration of the second stage and the risk of operative delivery, with nulliparous women having a higher risk compared to multiparous women.

Summary: This study investigated the association and potential value of prelabour fetal heart rate short-term variability (STV) determined by computerised cardiotocography (cCTG) and maternal and fetal Doppler in predicting labour outcomes. The results showed a weakly positive correlation between prelabour STV and umbilical cord arterial pH, but it was not predictive of emergency delivery due to pathological CTG during labour.

Summary: This study identified an effective method for extracting non-invasive fetal electrocardiogram (NI-fECG) from signals recorded from the mother's abdomen, combining independent component analysis (ICA), fast transversal filter (FTF), and complementary ensemble empirical mode decomposition with adaptive noise (CEEMDAN). Testing on two patient databases demonstrated that this combined method is capable of accurately extracting fECG with lower computational complexity.

Summary: To monitor fetal health and growth, fetal heart rate is a critical indicator. However, the quality of fetal ECG recordings is often affected by noises, making accurate fetal heart rate estimation challenging. This study proposes an unsupervised learning-based approach to assess the quality of fetal ECG signals, achieving a high accuracy in three-level quality classification and reducing errors in fetal heart rate estimation.

Summary: This study aims to provide reference values for 2D-STE, NI-fECG, and EHG parameters during the second trimester of pregnancy and investigate their diagnostic potential in the early detection of complications. By conducting a large-scale longitudinal prospective study, the research will analyze the diagnostic potential of these parameters in early to mid-term pregnancy.

Summary: Despite the widespread use of electronic fetal monitoring in labor and delivery, there is still debate about its value. Electronic fetal monitoring provides valuable data, but historically, the stored data are rarely reviewed systematically. A deep learning framework has been developed for early detection of preventable fetal injury, with 94% accuracy.

Summary: The independent component analysis (ICA) based methods combined with adaptive algorithms are commonly used for non-invasive fetal electrocardiogram (NI-fECG) processing. The study aims to test and objectively evaluate 11 variants of ICA methods combined with an adaptive fast transversal filter (FTF) to extract the NI-fECG. The combination of FastICA and FTF showed the best results with mean values of ACC = 83.72%, SE = 92.13%, PPV = 90.16%, and F1 = 91.14%. Rating: 8/10.

Summary: This study compared a novel self-applicable non-invasive fetal electrocardiography monitor with a computerized cardiotocography in terms of signal quality and heart-rate detection, and assessed the influence of maternal and fetal characteristics on both devices. The results showed that although the non-invasive fetal electrocardiography had higher signal loss, it was not affected by increased body mass index or fetal movement. The high accuracy of heart-rate indices is promising for the usage of non-invasive fetal electrocardiography in the remote setting.

Summary: This study reports a lightweight and user-friendly non-invasive wearable cardiac sensing system based on deformation-insensitive conductive gold nanowire foam and pressure-sensitive resistive gold nanowire electronic skin. The system enables real-time recording of electrocardiogram and artery pulses under dynamic real-world settings, and can also estimate blood pressure using machine learning algorithms.

Summary: Endothelial dysfunction in fetuses of women with gestational diabetes mellitus is associated with subsequent cardiovascular events. This study assessed fetal vascular endothelial function in GDM patients using color M-mode derived aortic propagation velocity (APV) and found a significant correlation between APV and vWF levels. The novel metric of APV could aid in early recognition of vascular functional alterations and potential risk factor surveillance and modification.

Summary: This work presents a functionalized optical fibre probe with 'cotton-shaped' gold-silica nanostructures for monitoring relative humidity (RH). The sensor utilizes the localized surface plasmon resonance (LSPR) of self-assembled nanostructures and demonstrates a high sensitivity to RH after optimization. The plasmonic hybridization mode sensor exhibited excellent linearity, reversibility, and fast response and recovery times.
