Abstract Background High stress prenatally contributes to poor maternal and infant well-being. The coronavirus disease 2019 (COVID-19) pandemic has created substantial for pregnant women. Purpose To understand whether experienced by women at the beginning of was associated with a greater prevalence adverse perinatal outcomes.

Abstract Objectives Pregnancies affected by opioid use disorder (OUD) face difficulties with postpartum pain control. This study aims to determine if prenatal anesthesia consultation for patients on medication (MOUD) affects maternal Methods is a retrospective cohort of pregnant diagnosed MOUD who received care and delivered at single academic institution between January 2017 July 2023. Subjects were divided into those did not. Severe (numerical rating scale 0–10) was defined as score≥7....

During labor, fetal heart rate (FHR) is monitored externally using Doppler ultrasound. This done continuously, but for various reasons (e.g., or maternal movements) the system does not record any samples varying periods of time. In many settings, it would be quite beneficial to estimate missing samples. this paper, we propose a (deep) Gaussian process-based approach estimation consecutively in FHR recordings. The method relies on similarities state space and exploiting concept attractor...

Introduction: During labor, fetal heart rate (FHR) and uterine activity (UA) can be continuously monitored using Cardiotocography (CTG). This is the most widely adopted approach for electronic monitoring in hospitals. Both FHR UA recordings are evaluated by obstetricians assessing well-being. Due to complex noisy nature of these recordings, evaluation suffers from high interobserver intraobserver variability. Machine learning a field that has seen unprecedented advances past two decades many...

The computer-aided interpretation of fetal heart rate (FHR) and uterine contraction (UC) has not been developed well enough for wide use in delivery rooms. main challenges still lie the lack unclear nonstandard labels cardiotocography (CTG) recordings, timely prediction state during monitoring. Rather than traditional supervised approaches to FHR classification, this paper demonstrates a way understand UC-dependent responses an unsupervised manner. In work, we provide complete method FHR-UC...

Low umbilical artery pH is a marker for neonatal acidosis and associated with an increased risk complications. The phase-rectified signal averaging (PRSA) features have demonstrated superior discriminatory or diagnostic ability good interpretability in many biomedical applications including fetal heart rate analysis. However, the performance of PRSA method sensitive to values selected parameters which are usually either chosen based on grid search empirically literature. In this paper, we...

During the process of childbirth, fetal distress caused by hypoxia can lead to various abnormalities. Cardiotocography (CTG), which consists continuous recording heart rate (FHR) and uterine contractions (UC), is routinely used for classifying fetuses as hypoxic or non-hypoxic. In practice, we face highly imbalanced data, where are significantly underrepresented. We propose address this problem boost ensemble learning, use distribution classification error over dataset. then iteratively...

Classification with imbalanced data is a common and challenging problem in many practical machine learning problems. Ensemble popular solution where the results from multiple base classifiers are synthesized to reduce effect of possibly skewed distribution training set. In this paper, binary based on Gaussian processes chosen as bases for inferring predictive distributions test latent variables. We apply process variable model outputs used making final decision. The tests new method both...

The coronavirus disease (COVID-19) has rapidly spread throughout the world and while pregnant women present same adverse outcome rates, they are underrepresented in clinical research.
