This pilot study aimed to understand the moderating role of context processing (i.e. encoding and memorizing) when mothers are confronted with threatening stimuli and undergo physiologic monitoring in order to understand a possible mechanism favoring intergenerational transmission of posttraumatic stress. Thirty-one mothers (M age = 33.87 years, SD = 4.14) and their toddlers (M age = 22.66 months, SD = 7.01) participated in the study. Mothers reported adverse life events (ALE), their current posttraumatic stress symptoms (PTSS), as well as regulatory problems of their toddler. Mothers performed a context-encoding and -memory (CEM) task including emotional facial expressions (especially angry faces considered as threatening stimuli) embedded into photo-backgrounds, after which they were asked to recognize both the faces and contexts. Maternal heart rate variability (HRV) was measured during resting state. Maternal current PTSS, but not ALE, had impact on child dysregulation only for mothers with poor context processing (β = 0.014, p = .017). Baseline HRV was negatively correlated with the recognition of contexts previously associated with angry faces (ρ = -.53, p = .006), and marginally with the recognition of angry faces (ρ = -.37, p = .059). This pilot study identifies psychophysiological markers (i.e. CEM, HRV) that may influence the intergenerational transmission of posttraumatic stress. This may open new avenues in early identification and intervention with traumatized mothers and their toddlers.

Parental support and acceptance are strong protective factors for better mental health outcomes among transgender and gender diverse youth. Psychological inflexibility, specifically in the role of parenting, or “parenting inflexibility”, refers to an over-reliance on avoidance strategies at the expense of parenting values. Parenting inflexibility may be related to parental support, making it a useful target of intervention for parents of transgender youth. The aim of the present study was to develop a brief clinically useful measure of parenting inflexibility based on a synthesis of existing measures and to evaluate the psychometric properties across two study populations. Study 1 used exploratory factor analysis to examine this measure among parents in the general population recruited using MTurk. Study 2 used confirmatory factor analysis to examine the measure among parents of transgender youth recruited from a clinic. The final measure, the Impact of Parenting Avoidance (IPA) scale, is a one-factor 7-item measure of parenting inflexibility that is easy to administer and interpret in a pediatric health setting. The resulting measure demonstrated acceptable reliability, and it was significantly correlated with important outcome variables, such as negative parenting practices and lower perceived parental support among transgender and gender diverse youth.

OBJECTIVE/UNASSIGNED:To examine the transition to telemental health within the behavioral health program of a large federally qualified health center, The Family Health Centers at NYU Langone, in the 3 months following the onset of the COVID-19 pandemic-specifically impacts on show rates and access to care. METHODS/UNASSIGNED:Demographic and clinical information for all scheduled visits was collected for two time periods: the telemental health period, March 16, 2020-July 16, 2020 (46,878 visits, 5,183 patients), and a comparison period, March 15, 2019-July 16, 2019 (47,335 visits, 5,190 patients). Data collected included modality, appointments scheduled/completed/cancelled/no-showed, age, gender, race, language, and diagnosis. Generalized estimating equations with a compound symmetry correlation structure and logit link were used for analysis. RESULTS/UNASSIGNED:= 0.01), which was eliminated by implementation of telemental health. CONCLUSIONS/UNASSIGNED:This study supports the use telemental health to increase access for all patients, including those from under-represented, lower socioeconomic status backgrounds.

A long-standing theory for Alzheimer's disease (AD) has been that deterioration of synapses and depressed neuronal activity is a major contributing factor. We review the increasing evidence, in humans and in mouse models, that show that there is often neuronal hyperactivity at early stages rather than decreased activity. We discuss studies in mouse models showing that hyperexcitability can occur long before plaque deposition and memory impairment. In mouse models, a generator of the hyperactivity appears to be the dentate gyrus. We present evidence, based on mouse models, that inhibition of muscarinic cholinergic receptors or medial septal cholinergic neurons can prevent hyperactivity. Therefore, we hypothesize the novel idea that cholinergic neurons are overly active early in the disease, not depressed. In particular we suggest the medial septal cholinergic neurons are overly active and contribute to hyperexcitability. We further hypothesize that the high activity of cholinergic neurons at early ages ultimately leads to their decline in function later in the disease. We review the effects of a prenatal diet that increases choline, the precursor to acetylcholine and modulator of many other functions. In mouse models of AD, maternal choline supplementation (MCS) reduces medial septal cholinergic pathology, amyloid accumulation and hyperexcitability, especially in the dentate gyrus, and improves cognition.

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.

BACKGROUND/UNASSIGNED:Essential tremor (ET) is characterized by often disabling action tremors. No pharmacological agent has been developed specifically for symptomatic treatment. Anecdotal reports describe tremor improvement with cannabis, but no evidence exists to support these claims. We conducted a phase Ib/II double-blind, placebo-controlled, crossover pilot trial in participants with ET to investigate tolerability, safety, and efficacy of Tilray TN-CT120 LM, an oral pharmaceutical-grade formulation containing tetrahydrocannabinol (THC) 5 mg and cannabidiol (CBD) 100 mg. Our objectives were to determine if short-term THC/CBD exposure improved tremor amplitude and was tolerated. METHODS/UNASSIGNED:Participants with ET were randomized (1:1) to receive either TN-CT120 LM or placebo. Dose titration, driven by tolerability, was attempted every 2-3 days to three capsules daily maximum. Participants remained on the highest tolerated dose for two weeks before returning to complete assessments. After completing the first arm, participants titrated off the agent, underwent a three-week washout, and then returned for the same procedures with the alternate compound. The primary endpoint was tremor amplitude change from baseline using digital spiral assessment. Secondary endpoints explored safety and tolerability. RESULTS/UNASSIGNED:Among thirteen participants screened, seven were eligible and enrolled. Five completed all visits; one withdrew following a serious adverse event, and another did not tolerate the lowest dose. Intent-to-treat analyses performed for six participants did not reveal significant effects on primary or secondary endpoints. CONCLUSIONS/UNASSIGNED:This pilot trial did not detect any signals of efficacy of THC/CBD in ET. Although preliminary due to the small sample size, our data do not support anecdotal reports of cannabinoid effectiveness for ET. HIGHLIGHTS/UNASSIGNED:This double-blind, randomized, placebo-controlled efficacy and tolerability pilot trial did not detect any signals of efficacy of oral cannabidiol and tetrahydrocannabinol in reducing essential tremor amplitude using either digital outcome measures or clinical rating scales. The oral cannabinoids were well-tolerated by most (five out of seven) participants.

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/BACKGROUND:Maternal undernutrition and inflammation in utero may significantly impact the neurodevelopmental potential of offspring. However, few studies have investigated the effects of pregnancy interventions on long-term child growth and development. This study will examine the effects of prenatal nutrition and infection management interventions on long-term growth and neurodevelopmental outcomes of offspring. METHODS:The Enhancing Nutrition and Antenatal Infection Treatment ('ENAT') study (ISRCTN15116516) was a pragmatic, open-label, 2×2 factorial, randomised clinical effectiveness study implemented in 12 rural health centres in Amhara, Ethiopia. The study enrolled 2399 pregnant women who were randomised to receive routine care, an enhanced nutrition package (iron and folic acid, monthly household supply of iodised salt, and micronutrient-fortified balanced energy protein supplement for undernourished women), an enhanced infection management package (genitourinary tract infection screening and treatment, and enhanced deworming), or both packages. In the present Longitudinal Infant Development and Growth study, a subset of 480 children of mothers from ENAT will be recruited equally from each of the four study arms and visited at 12, 18, and 24 months of postnatal age. We will evaluate a range of domains and deploy multiple measures to assess child neurodevelopment, including resting electroencephalography and visual evoked potentials, Hammersmith Infant Neurological Examination, eye-tracking, Bayley Scales of Infant and Toddler Development (Bayley-III), and Magnetic Resonance Imaging (MRI). DISCUSSION/CONCLUSIONS:This study will advance understanding of the impact of nutrition and inflammation in pregnancy on long-term offspring neurodevelopment. This study aims to fill a critical knowledge gap on the benefits of prenatal interventions to promote the health of mothers and their offspring. ETHICS AND DISSEMINATION/BACKGROUND:This study was approved by the Institutional Review Boards of Addis Continental Institute of Public Health (ACIPH/IRB/002/2022) and Mass General Brigham (2023P000461). Results will be disseminated to local and international stakeholders. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT06296238.

PURPOSE/OBJECTIVE:Children and adolescents are experiencing a mental health crisis. Neurodiverse patients have high rates of mental health conditions and worse outcomes. To address this disparity, the Autism Spectrum Disorder Care Pathway was applied to a pediatric emergency department (PED) and Observation Unit (OU) in order to decrease agitation experienced by these patients. METHODS:This prospective cohort study was in a community-based PED and OU from June 2023 to February 2024. A medical education curriculum consisting of a multidisciplinary champion training and toolkit rollout was completed. Agitation was measured by the Behavioral Activity Rating Scale. The primary aim was to decrease frequency of agitation experienced by neurodiverse patients at any point in the PED/OU. The secondary outcome was to decrease pharmacologic intervention and physical restraint use. RESULTS:We captured data from a total of 45 patients, with 19 baseline patients and 26 patients in the intervention group. At baseline, 9 out of 19 (47%) patients experienced agitation at some point in their PED/OU stay. After implementation of the curriculum, agitation levels decreased to 6 out of 26 (23%) patients (p = 0.04). Inter-rater reliability was 0.95. There were 3 incidences of pharmacologic intervention and no physical restraint use. CONCLUSIONS:This pilot medical education curriculum for PED and OU staff members decreased agitation in neurodiverse patients who presented for mental health complaints. This study is the foundation for expansion of the curriculum for use in general emergency departments.
