Maternal Perception of Infant Sleep and Bonding in Opioid Use Disorder.

Objective: Infant sleep problems are common in early infancy and can negatively influence maternal-infant bonding. As opioid-exposed neonates are at increased risk of sleep difficulties, we examined the association between maternal perception of infant sleep difficulties and maternal-infant bonding among dyads affected by maternal opioid use disorder (OUD), from birth through 6 months.

Methods: We enrolled 100 birthing people (participants) between 6 months and 2 years postpartum who had received medications for OUD during their pregnancy.

A quiescent state following mild sensory arousal in Caenorhabditis elegans is potentiated by stress.

An animal's behavioral and physiological response to stressors includes changes to its responses to stimuli. How such changes occur is not well understood. Here we describe a Caenorhabditis elegans quiescent behavior, post-response quiescence (PRQ), which is modulated by the C.

Comparing Caenorhabditis elegans gentle and harsh touch response behavior using a multiplexed hydraulic microfluidic device.

The roundworm Caenorhabditis elegans is an important model system for understanding the genetics and physiology of touch. Classical assays for C. elegans touch, which involve manually touching the animal with a probe and observing its response, are limited by their low throughput and qualitative nature.
