Quantifying Arm and Leg Movements in 3-Month-Old Infants Using Pose Estimation: Proof of Concept.

Background: Pose estimation (PE) has the promise to measure pediatric movement from a video recording. The purpose of this study was to quantify the accuracy of a PE model to detect arm and leg movements in 3-month-old infants with and without (TD, for typical development) complex congenital heart disease (CCHD).

Methods: Data from 12 3-month-old infants (N = 6 TD and N = 6 CCHD) were used to assess MediaPipe's full-body model.

Coparenting Patterns of Parents of an Infant With Complex Congenital Heart Disease: Qualitative Identification and Network Analysis of Effects of Infant Illness Severity and Guided Participation Intervention.

The purpose of this secondary analysis, from a pilot randomized controlled trial of guided participation (GP), was to describe patterns of coparenting for mother and father dyads caring for an infant with complex congenital heart disease and to examine the influencing factors at infant age 6 months. Our theoretical framework included GP treatment, severity of neonatal illness (severity), coparenting pattern, and parent attention to infant weight gain (weight gain). From transcribed interviews with 25 parent dyads at infant age 2 and 6 months, data relevant to coparenting were categorized for entry into a matrix table.

Biobehavioral Efficacy of the Elevated Side-Lying Position for Feeding Preterm Infants: Study Protocol.

Aim: Present a study protocol investigating the biobehavioral efficacy of side-lying vs. supine positions on physiologic and behavioural responses of preterm infants during their transition from tube to full oral feeding, and identify associated infant characteristics.

Design: Within-subject cross-over design.

The formation of the Bicoid morphogen gradient requires protein movement from anteriorly localized mRNA.

The Bicoid morphogen gradient directs the patterning of cell fates along the anterior-posterior axis of the syncytial Drosophila embryo and serves as a paradigm of morphogen-mediated patterning. The simplest models of gradient formation rely on constant protein synthesis and diffusion from anteriorly localized source mRNA, coupled with uniform protein degradation. However, currently such models cannot account for all known gradient characteristics.

Median household income and mortality rate in cystic fibrosis.

Context: Poverty has been shown to be a determinant of health outcomes in many epidemiologic studies.

Objective: The goal of this study was to assess the association between household income and the mortality rate in cystic fibrosis (CF) patients.

Design, Setting, And Patients: We selected white patients diagnosed before 18 years old and having 1 or more records in the Cystic Fibrosis Foundation Patient Registry since 1991.
