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.

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: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.

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.

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.

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.

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.

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.
