Hush, little baby: The role of C-tactile afferents in babywearing infants with neonatal opioid withdrawal.

Social touch through infant holding, skin-to-skin contact, and infant carrying (babywearing) decreases infant distress and promotes secure attachment. Unknown is the extent to which these effects are the result of the activation of C-Tactile afferents (CTs), the constellation of nerve fibers associated with affective touch, primarily located in the head and trunk of the body. The purpose of the present study was to compare dynamic touch (CTs activated) to static touch (CTs less activated) during a babywearing procedure among infants experiencing Neonatal Opioid Withdrawal Syndrome (NOWS).

Frequency-Based Maternal Electrocardiogram Attenuation for Fetal Electrocardiogram Analysis.

Fetal electrocardiogram (ECG) waveform analysis along with cardiac time intervals (CTIs) measurements are critical for the management of high-risk pregnancies. Currently, there is no system that can consistently and accurately measure fetal ECG. In this work, we present a new automatic approach to attenuate the maternal ECG in the frequency domain and enhance it with measurable CTIs.

Noninvasive Fetal Electrocardiography in the Diagnosis of Long QT Syndrome: A Case Series.

Introduction: Early detection and monitoring for malignant arrhythmias is fundamental to prenatal care in long QT syndrome (LQTS). Recently, we studied the feasibility of isolating the fetal electrocardiogram (fECG) and measuring electrocardiographic intervals with a noninvasive fECG device using blind source separation with reference signal. Our aim was to evaluate the ability of fECG to diagnose LQTS.
