Abstract
A recent experiment probed how purposeful action emerges in early life by manipulating infants' functional connection to an object in the environment (i.e., tethering an infant's foot to a colorful mobile). Vicon motion capture data from multiple infant joints were used here to create Histograms of Joint Displacements (HJDs) to generate pose-based descriptors for 3D infant spatial trajectories. Using HJDs as inputs, machine and deep learning systems were tasked with classifying the experimental state from which snippets of movement data were sampled. The architectures tested included k-Nearest Neighbour (kNN), Linear Discriminant Analysis (LDA), Fully connected network (FCNet), 1D-Convolutional Neural Network (1D-Conv), 1D-Capsule Network (1D-CapsNet), 2D-Conv and 2D-CapsNet. Sliding window scenarios were used for temporal analysis to search for topological changes in infant movement related to functional context. kNN and LDA achieved higher classification accuracy with single joint features, while deep learning approaches, particularly 2D-CapsNet, achieved higher accuracy on full-body features. For each AI architecture tested, measures of foot activity displayed the most distinct and coherent pattern alterations across different experimental stages (reflected in the highest classification accuracy rate), indicating that interaction with the world impacts the infant behaviour most at the site of organism~world connection.

Establishing Optimal Control Cohorts for Phase 1 Trials: Retrospective Analysis of Clinical and Biological Outcomes in Neonates and Infants Undergoing Two-Ventricle Repair. Pediatr Cardiol 2024:10.1007/s00246-024-03550-5.

Abstract
Phase 1 trials are primarily conducted to evaluate the safety and feasibility of new interventions, usually without recruiting control patients. This retrospective study aims to characterize clinical and biological outcomes in historical and contemporary cases of neonates and infants undergoing two-ventricle repair to facilitate future secondary endpoint analyses for such trials. This retrospective study included neonates/infants (ages ≤ 6 months) who underwent two-ventricle repair between 2015 and 2021 using the same criteria as our phase 1 trial (n = 199). Patients were allocated into the ventricular septal defect (n = 61), the Tetralogy of Fallot (TOF, n = 88), and the transposition of the great arteries (n = 50) groups with an additional comparison between two eras (2015-2019 vs. 2020-2021). Patient characteristics and most variables assessed were different between the three diagnostic groups indicating the importance of diagnostic matching for secondary analyses. Although the era did not alter cerebral/somatic oxygenation, ventricular function, neuroimaging findings, and complication rates, we observed improvement of inotropic and/or vasoactive-inotropic scores in all groups during the more recent era. In 2020-2021, the age and the body weight at the operation were higher, and hospital stay was shorter in the TOF group, suggesting the possible impact of the pandemic. Results also indicated that matching altered characteristics such as age at operation that may limit the temporal effects and optimize secondary analyses. Using optimal contemporary cases and historical data based on this study will assist in developing a comprehensive study design for a future efficacy/effectiveness trial.

Abstract
Neurological deficits are a serious and common sequelae of congenital heart disease (CHD). While their underlying mechanisms have not been fully characterized, their manifestations are well-known and understood to persist through adulthood. Development of therapies to address or prevent these deficits are critical to attenuate future morbidity and improve quality of life. In this review, we aim to summarize the current status of neuroprotective therapy in CHD. Through an exploration of present research in the pre-operative, intra-operative, and post-operative phases of patient management, we will describe existing clinical and bench efforts as well as current endeavors underway within this research area.

Abstract
CONTEXT With improvements in survival rates in newborns with congenital heart defects (CHDs), focus has now shifted toward enhancing neurodevelopmental outcomes across their life span. OBJECTIVE To systematically review the prevalence and extent of motor difficulties in infants, children, and adolescents with CHD requiring open-heart surgery. DATA SOURCES Data sources included Embase, Medline and the Cumulative Index to Nursing and Allied Health Literature. STUDY SELECTION Original studies published between 1997 and 2019 examining gross and/or fine motor skills in children born with a CHD requiring open-heart surgery were selected. DATA EXTRACTION The prevalence of motor impairments and mean scores on standardized motor assessments were extracted. Findings were grouped in 5 categories on the basis of the age of the children. RESULTS Forty-six original studies were included in this systematic review. The prevalence of mild to severe motor impairments (scores <-1 SD below normative data or controls) across childhood ranged from 12.3% to 68.6%, and prevalence ranged from 0% to 60.0% for severe motor impairments (<-2 SDs). Although our results suggest that the overall prevalence of motor impairments <-1 SD remains rather constant across childhood and adolescence, severe motor impairments (<-2 SDs) appear to be more prevalent in younger children. LIMITATIONS Variability in sampling and methodology between the reviewed studies is the most important limitation of this review. CONCLUSIONS The results of this review highlight that infants with CHD have an increased risk of motor impairments across infancy, childhood, and adolescence. These findings stress the importance of systematic screening or evaluation of motor skills across childhood and adolescence in children with CHD.

Abstract
Contingent learning is an agent for infants to explore the environment, which enhances the maturation of different developmental domains. This paper presents one of the first to investigate neural activities related to contingent learning of infants by analyzing their motor response that could elicit an audio-visual feedback. Three different kinds of motor response of infants were investigated, including unilateral kicks, synchronized kicks, and alternate kicks. Electroencephalographic (EEG) signals of infants were recorded before the motor experiments. Higher theta band power and lower upper beta power at the right temporal lobe of infants predicted a higher ratio of total unilateral kicks and a lower ratio of synchronized kicks at the later acquisition stage of the experiment. As contingent learning could be reflected by specific motor response in relation to the audio-visual stimuli, the results suggested that right temporal oscillations could predict different levels of contingent learning of infants.

Abstract
BACKGROUND The timing and coordination of infant kicking may allow for activities that facilitate learning and cognitive development. OBJECTIVE This study examined spontaneous kicking and associations with changes in kicking during a learning paradigm in typically developing infants. METHODS Ten healthy full-term infants participated in two experiments at 3 months of age: spontaneous kicking and the mobile paradigm. The inter-limb, intra-limb, and spatiotemporal parameters during spontaneous kicking were collected by 3D motion capture. Learning was measured in the mobile paradigm where an infant's leg was tethered to an overhead mobile. The mobile offered visual and auditory reinforcement when the infant kicked. Changes in kicking rate indicate learning. Friedman tests were used to determine the dominant inter-/intra-limb kicking patterns. Spearman's rank correlation coefficients were used to assess the correlations between spontaneous kicking and performance in the mobile paradigm. RESULTS A significant negative correlation (r = -0.72, p = 0.03) was observed between the percentages of unilateral kicking and normalized kicking rate during the extinction phase of the paradigm. There was a trend of positive correlation (r = 0.58, p < 0.10) between dissociated hip-ankle joint coupling and the last three-minute of the acquisition phase of the paradigm. CONCLUSION Exploratory kicking behaviors elicited by visual and auditory feedback may be related to lower extremity movement control. Enhancing movement experience through appropriate external feedback may be critical in treatment programs to support infant development. Future studies to assess how exploratory motor behaviors contribute to development in motor and other domains are warranted.

Abstract
As survivable outcomes among patients with complex congenital heart disease (cCHD) have continued to improve over the last several decades, more attention is being dedicated to interventions that impact not just survival but quality of life among patients with cCHD. In particular, patients with cCHD are at risk for impaired neurodevelopmental outcomes. In this review summarizing select presentations given at the 14th Annual Pediatric Cardiac Intensive Care Society's Annual Meeting in 2019, we discuss the neurodevelopmental phenotype of patients with cCHD, patients at greatest risk of impaired development, and three specific modifiable risk factors impacting development.

Abstract
BACKGROUND Associative learning is the ability to discover a relationship between two or more events. We combined principles of learning and technology to develop a paradigm to assess associative learning in prone. PURPOSE The purpose of this study was to determine whether 3- to 6-month-old infants can demonstrate: (1) short-term learning of an association between their upper body movements in prone and activation of a toy, and (2) retention of the association learned on day 1, 24 hours later. METHODS Twenty-eight infants who were 3 to 6 months of age and who were typically developing were tested for 2 consecutive days in an instrumented play gym. Both days of testing had a baseline and 4 acquisition phases (2 minutes each). During the acquisition phase, the toy activated for a maximum of 10 seconds when the infant's head was above a threshold. A criterion was set a priori to distinguish infants as short-term learners and retainers of the association learned on day 1. RESULTS Of 28 infants, 22 and 14 infants completed all phases of the testing on day 1 and day 2, respectively. Fourteen (50%) of the infants met the criteria for short-term learners. On day 2, there was an analyzable sample of 9 short-term learners. Three of the 12 short-term learners (25%) demonstrated retention on day 2. CONCLUSION Consistent with prior infant motor learning research, half of the infants demonstrated associative learning in this novel assessment in prone; however, based on study criteria, the infants had limited retention of the association on day 2.
