Toddler visual attention development correlates with subsequent language, cognitive, and social developmental outcomes. This study investigates the association of maternal trauma on toddler looking behaviors in 39 mother-child dyads from the Western Cape Province, South Africa. At 15 months postpartum, maternal trauma was assessed using the Life Events Checklist and toddler multisensory attention skills were measured using the Multisensory Attention Assessment Protocol (MAAP) during eye-tracking. We used two-way mixed ANOVA to analyze the association of maternal trauma and MAAP condition with attention maintenance, intersensory matching, and attention shifting. This study provides support for the MAAP's reliability with a sample of 15-month-old toddlers from a low-income setting. We observed a significant interaction between MAAP condition and maternal trauma group on attention maintenance, but pairwise comparisons did not meet the threshold for statistical significance. In a stratified analysis, toddlers of mothers in the low trauma exposure group demonstrated significant differences in attention maintenance, intersensory matching, and attention shifting by condition. Unexpectedly, toddlers of mothers in the high trauma exposure group did not exhibit significant differences in these attentional skills, potentially indicating attentional adaptations. Further research is needed to explore the relationship between the intergenerational transmission of trauma on infant and toddler multisensory attention skills in low-income settings.

BACKGROUND/UNASSIGNED:Magnetic resonance imaging (MRI) and electroencephalography (EEG) are valuable tools for studying neuroanatomical and electrophysiological features of early brain development. Studies implementing neuroimaging tools in low- and middle-income countries are still rare, and there is limited data on the acceptability of such tools among rural communities. The present study explores the perceptions, feasibility, and acceptability of introducing MRI and EEG for child development research in the rural Amhara region of Ethiopia. METHODS/UNASSIGNED:= 16). A semi-structured interview included four themes: (1) Baseline imaging knowledge, (2) Perceptions of MRI and EEG, (3) Facilitators and barriers to acceptability of MRI and EEG, and (4) Recommendations to improve MRI and EEG uptake. Interviews were conducted in Amharic, the local language. All interviews were transcribed verbatim to Amharic, translated into English, and double-coded. We used thematic analysis to organize data according to predefined and emerging themes. RESULTS/UNASSIGNED:Knowledge of MRI and EEG was limited, and none of the community members had previous experiences with either technology. Broadly, participants responded positively to our introductory videos showing MRI and EEG acquisition and expressed high levels of acceptability. However, participants reported concerns about possible harms related to radiation, electrical shock, and injury from MRI/EEG procedures. Those with lesser education were identified to be less accepting of MRI/EEG. In addition, several mothers expressed that consent from their husbands was necessary for their child's participation in neurodevelopmental research. Potential logistical barriers identified included transportation challenges to the neuroimaging study sites, especially for rural-dwelling families. Creating awareness, using explanatory videos, and engaging community members and clinicians were recommended to facilitate acceptance of EEG and MRI. CONCLUSION/UNASSIGNED:In this formative study, MRI and EEG were viewed as acceptable methods for assessing child neurodevelopment in rural areas of Ethiopia. Community members' and clinicians' views were impacted largely by social, religious, educational, and logistical aspects. Concerns related to MRI radiation, electrical shock, and injuries from EEG can be addressed through awareness creation and education. Engaging community leaders and healthcare providers is key to improving acceptability.

BACKGROUND/UNASSIGNED:Attention Deficit Hyperactivity Disorder (ADHD) among children younger than 6 years is quite impairing, nearly half these youth with ADHD experience school exclusion from mainstream preschool classes due to related emotional and behavioral outbursts. While a range of behavior rating scales and subjective measures are used to assess these youth, objective methods of assessment and prediction derived from technology have potential to improve therapeutic and academic interventions outcomes for these youths. We hypothesized that biometric sensors would provide objective, highly sensitive and specific information regarding the physiological status of children prior to an impulsive outburst and could be feasibly implemented using a wearable device in the special education classroom. METHODS/UNASSIGNED: = 5 youth from the first grade) of a specialized therapeutic day-school for youth with ADHD and other psychiatric and developmental disorders to examine feasibility of obtaining continuous physiological data associated with behavioral and emotional outbursts through smartwatch use. Children wore a sensor watch during their daily classroom activities for two weeks and trained observers collected data using behavioral logs. Using Ecological Momentary Assessment methodology, to examine correlations between objective sensor data and observer observation. Data collected from parents regarding prior night's sleep was also examined. RESULTS/UNASSIGNED:All participants completed the study. With a few tolerability or palatability issues. Associations were found between physiological and behavioral/questionnaire data. The methodology holds promise for reliably measuring behavioral and emotional outbursts in young children. CONCLUSIONS/UNASSIGNED:among severely dysregulated pre-school aged youth throughout a full school day. This study established the feasibility of utilizing sensor derived physiological data as an objective biomarker of ADHD within the special education therapeutic classroom. Further research with larger samples is required to build a more robust and personalized AI predictive model.

Preterm birth poses a major public health challenge, with significant and heterogeneous developmental impacts. Latent profile analysis was applied to the National Institutes of Health Toolbox performance of 1891 healthy prematurely born children from the Adolescent Brain and Cognitive Development study (970 boys, 921 girls; 10.00 ± 0.61 years; 1.3% Asian, 13.7% Black, 17.5% Hispanic, 57.0% White, 10.4% Other). Three distinct neurocognitive profiles emerged: consistently performing above the norm (19.7%), mixed scores (41.0%), and consistently performing below the norm (39.3%). These profiles were associated with lasting cognitive, neural, behavioral, and academic differences. These findings underscore the importance of recognizing diverse developmental trajectories in prematurely born children, advocating for personalized diagnosis and intervention to enhance care strategies and long-term outcomes for this heterogeneous population.

INTRODUCTION/UNASSIGNED:Assessing sustained attention presents methodological challenges, particularly when spanning diverse populations whose baseline sensorimotor functioning may vary significantly. METHODS/UNASSIGNED:This study introduces the Continuous Performance Critical Stability Task (cpCST), a novel paradigm combining high-density sampling of behavior (30 Hz), individualized calibration, and fixed-difficulty assessment to measure attentional control. In a sample of 166 adults (ages 18-76), we evaluated the psychometric properties of the cpCST's instantaneous reaction time (iRT) metric derived through dynamic time warping. RESULTS/UNASSIGNED:The cpCST demonstrated exceptional reliability (bootstrap split-half r = 0.999) and predictive validity for cognitive performance (flanker and Woodcock-Johnson) and cardiorespiratory fitness (VO2submax). The task achieved high temporal efficiency, with just 2 min of data correlating at r = 0.94 with full-task performance, outperforming a standard arrow-based flanker task. The cpCST's individualized calibration effectively isolated attentional control processes from baseline sensorimotor function, eliminating age-related slowing effects typically observed in reaction time tasks. DISCUSSION/UNASSIGNED:This approach offers methodological advantages for lifespan studies, clinical populations, integration with neurophysiological measures, and computational modeling approaches while addressing limitations of existing attention assessment paradigms.

INTRODUCTION/BACKGROUND:During the COVID-19 pandemic, birthing parents were identified as a high-risk group with greater vulnerability to the harms associated with SARS-CoV-2. This led to necessary changes in perinatal health policies but also to experiences of maternal isolation and loneliness, both in hospital settings, due to infection mitigation procedures, and once home, due to social distancing. METHODS:In this study, we qualitatively explored birthing and postpartum experiences in New York City during the early days of the pandemic when lockdowns were in effect and policies and practices were rapidly changing. Using thematic analysis, our focus was on experiences of isolation, navigating these experiences, and the potential impacts of isolation and loneliness on maternal health for 55 birthing people. RESULTS:Participants described numerous stressors related to isolation during the birthing process, including reconciling their hopes for their birth with the realities of the unknown and separation from partners, family, and friends in the hospital. During the postpartum period, loneliness manifested as having limited or no contact with family and friends, which led to feelings of a need for strengthened social support systems. The impact of these negative experiences shaped mental health. Overall, we found that solitary experiences during birthing and postpartum isolation were major sources of stress for participants in this study. DISCUSSION/CONCLUSIONS:To support impacted families and prepare for future crisis events, clinicians and researchers must prioritize the development of strong clinical and social support structures for perinatal people to ensure both maternal and child health.

BACKGROUND/UNASSIGNED:Complementary and integrative health (CIH) services enhance physiological and psychological wellbeing, while potentially reducing medical costs. Despite these benefits, use of inpatient CIH services remains poorly characterized, impeding efforts to develop equitable and effective healthcare. OBJECTIVE/UNASSIGNED:This retrospective case-control study examined characteristics of patients likely to receive CIH referrals and consults. METHOD/UNASSIGNED:Electronic health records were analyzed from patients hospitalized at a large metropolitan academic medical center from September 2022 to February 2024. RESULTS/UNASSIGNED:values <0.001). Among those referred, 72% received at least one CIH consult, with lower odds of completing a consult for male patients. CONCLUSION/UNASSIGNED:Disparities underscore the need for equitable CIH services access in healthcare systems. Future research will test how to broaden services to male patients, those with non-English language preference, and less medical complexity, to ensure greater benefit from holistic healthcare.

INTRODUCTION/UNASSIGNED:Individuals with Down syndrome (DS) exhibit neurological deficits throughout life including the development of in Alzheimer's disease (AD) pathology and cognitive impairment. At the cellular level, dysregulation in neuronal gene expression is observed in postmortem human brain and mouse models of DS/AD. To date, RNA-sequencing (RNA-seq) analysis of hippocampal neuronal gene expression including the characterization of discrete circuit-based connectivity in DS remains a major knowledge gap. We postulate that spatially characterized hippocampal neurons display unique gene expression patterns due, in part, to dysfunction of the integrity of intrinsic circuitry. METHODS/UNASSIGNED:We combined laser capture microdissection to microisolate individual neuron populations with single population RNA-seq analysis to determine gene expression analysis of CA1 and CA3 pyramidal neurons and dentate gyrus granule cells located in the hippocampus, a region critical for learning, memory, and synaptic activity. RESULTS/UNASSIGNED:The hippocampus exhibits age-dependent neurodegeneration beginning at ~6 months of age in the Ts65Dn mouse model of DS/AD. Each population of excitatory hippocampal neurons exhibited unique gene expression alterations in Ts65Dn mice. Bioinformatic inquiry revealed unique vulnerabilities and differences with mechanistic implications coinciding with onset of degeneration in this model of DS/AD. CONCLUSIONS/UNASSIGNED:These cell-type specific vulnerabilities may underlie degenerative endophenotypes suggesting precision medicine targeting of individual populations of neurons for rational therapeutic development.
