Reissue of RFA-20-351.The purpose of this Notice of Funding Opportunity (NOFO) is to encourage applications to pursue invasive neural recording studies focused on mental health-relevant questions. Invasive neural recordings provide an unparalleled window into the human brain to explore the neural circuitry and neural dynamics underlying complex moods, emotions, cognitive functions, and behaviors with high spatial and temporal resolution. Additionally, the ability to stimulate, via the same electrodes, allows for direct causal tests by modulating network dynamics. This funding opportunity aims to target a gap in the scientific knowledge of neural circuit function related to mental health disorders. Researchers should target specific questions suited to invasive recording modalities that have high translational potential. Development of new technologies and therapies are outside the scope of this NOFO.

BACKGROUND. Border identity groups—such as those who are bisexual/pansexual (bi+), Biracial/Multiracial, or gender nonbinary—challenge our nation's most basic group dichotomies (e.g., gay/straight, Black/White, man/woman) and are rapidly growing segments of the U.S. population. As NIH health disparity populations, it is unsurprising that border identity groups tend to demonstrate elevated HIV and mental health inequities as compared with the general U.S. population. However, more vexing are studies showing that bi+, Multiracial, and nonbinary people demonstrate greater sexual/mental health risk than their respective monosexual minority, monoracial minority, and binary gender minority counterparts. The potential drivers of these co-occurring health inequities are insufficiently theorized, poorly measured, and unevenly studied across groups. Yet, accumulating research supports an intriguing hypothesis—that bi+, Multiracial, and nonbinary populations demonstrate similar health risk profiles because, beyond traditional minority stressors, they are vulnerable to a distinct set of stigma-related stressors encountered by individuals holding identities that defy socially sanctioned dichotomies (i.e., border identity stressors). OBJECTIVE. In response to NIMH PAR-23-062 and NOT-MH-23-270, this R01 builds upon preliminary research to (a) develop a multigroup measure of border identity stress, (b) test a unified model of border identity stress, HIV risk, and mental health problems among bi+, Multiracial, and nonbinary adults, and (c) identify mutable mechanisms and protective factors concerning relations between border identity stress and co-occurring sexual and mental health risks. SPECIFIC AIMS. PI Jackson will work with Co-Is Bowleg, Esserman, Huynh, and Poteat to: develop a community-informed multigroup border identity stress scale—optimized for cross-sectional, longitudinal, and EMA HIV research (Aim 1); test longitudinally a conceptual model of border identity stress, HIV risk, and mental health—testing theorized mediators and moderators across bi+, Multiracial, and nonbinary adults (Aim 2); and detect relations between border identity stressors, daily HIV risk factors, and mental health symptoms among three higher-risk border identity subgroups via a 14-day microlongitudinal study—isolating daily mechanisms for intervention (Aim 3). SIGNIFICANCE. By highlighting how previously hidden forms of stigma drive health risk among bi+, Multiracial, and nonbinary adults, this model is poised to facilitate the development of much-needed interventions among three NIH health disparity groups disproportionately burdened by HIV—and is poised to shift how the field conceptualizes stigma, measures stigma-related stress, and combines stigmatized groups for study. DISSEMINATION. In addition to scholarly publications, we will produce and disseminate several scientific products (e.g., infographic summaries) for community members and health professionals, including: (1) bi+, Multiracial, and nonbinary research participants, (2) AIDS service organizations within Ending the HIV Epidemic priority jurisdictions, and (3) a national network of mental health providers serving stigmatized clients.

Project Summary / Abstract Chronic stress is a well-established contributor to neurobiological changes that influence behavioral responses to threat and uncertainty. The hippocampus plays a central role in stress-related plasticity, yet the specific circuits and molecular mechanisms through which stress alters hippocampal output remain incompletely defined. One pathway of interest is the projection from the ventral hippocampus to the medial prefrontal cortex (vHipp–mPFC), which has been implicated in modulating behavioral reactivity to aversive stimuli. My preliminary data indicate that chronic unpredictable stress (CUS) enhances activity in this circuit, coinciding with increased defensive behavioral responses. The current project aims to uncover the transcriptional mechanisms driving stress-induced hyperactivity in the vHipp–mPFC circuit and assess its causal role in stress-related behavioral adaptations. In Specific Aim 1, I will use circuit-specific labeling combined with single-nucleus RNA sequencing (snRNAseq) to identify stress-induced transcriptional changes in the vHipp–mPFC pathway following CUS. Then, I will assess the relevance of these changes to human pathology by comparing differentially expressed genes to single-nucleus data collected from individuals with post-traumatic stress disorder (PTSD) using the PsychENCODE human hippocampal PTSD dataset. In Specific Aim 2, I will use chemogenetic tools to bidirectionally manipulate vHipp–mPFC pathway activity in mice exposed to CUS to determine whether hyperactivity in this pathway is necessary and/or sufficient to drive changes in defensive behavior. The proposed research will advance our understanding of how chronic stress alters hippocampal-prefrontal circuits to influence behavior, potentially identifying new biomarkers or molecular targets for therapeutic development. The project integrates transcriptomic profiling, circuit-level manipulation, and behavioral analysis, providing me with comprehensive and rigorous training in both bioinformatics and systems neuroscience and preparing me for a career that integrates these fields to elucidate the neurobiology of stress-related disorders.

NIA - National Institute on Aging

PROJECT SUMMARY Aging is characterized by the gradual loss of physiological integrity, and this process may be accelerated in the presence of obesity, increasing susceptibility to disease, frailty, and death. Although the shared molecular pathways involved have not been fully elucidated, adipose tissue dysfunction is likely a key contributor to multisystem functional decline in aging and obesity. Despite growing evidence that β3 adrenergic receptor {β3AR) mediated activation of brown adipose tissue {BAT) may alter pathophysiological pathways implicated in various aging-related diseases including metabolic, cardiovascular, and neurodegenerative diseases, BAT has been largely ignored in aging research. In this highly innovative study, we propose to conduct a randomized, double-blind, placebo-controlled trial to investigate whether treatment with a β3AR agonist (vibegron) can improve energy metabolism, cardiometabolic risk factors, and physical and cognitive function. Vibegron {Gemtesa) was FDA-approved in 2020 for the treatment of overactive bladder and has greater selectivity, potency, and activity at the β3AR than other agonists studied to date. This presents a timely opportunity to explore pharmacological activation of β3ARs as a way to improve multiple health outcomes relevant in aging and obesity. To test our hypothesis, 40 middle-aged and older adults {45-75 yrs) with obesity will be randomized to vibegron {75 mg/day) or placebo for 12 weeks to compare their effects on various bioenergetic, cardiometabolic, physical function, and cognitive outcomes. Specifically, in Aim 1 we will assess the effects of vibegron vs. placebo on energy expenditure, core body temperature, mitochondrial bioenergetics, and thermogenic protein expression. In Aim 2 we will assess the effects of vibegron vs. placebo on glucose and insulin indices, lipid levels, body composition, and body fat distribution. In Aim 3 we will assess the effects of vibegron vs. placebo on self-report and objective measures of lower extremity function, muscle strength and pOY1er, global cognition, memory, executive function, quality of life, and depression. Notable innovations include blood-based bioenergetic profiling to assess systemic mitochondrial function, isolation and characterization of adipose tissue-derived small extracellular vesicles to assess target engagement, and continuous monitoring of core body temperature to assess circadian thermoregulation. In exploratory analyses we will compare the effects of vibegron vs. placebo on the accumulation of health deficits {i.e., frailty) and the preservation of physical and mental abilities {i.e., intrinsic capacity), two integrated measures of phenotypic aging that will provide estimates of the potential for vibegron to impact multisystem functional decline. This unique study will be the first clinical trial to explore the potential to repurpose vibegron for the treatment of aging-related obesity and associated comorbidities. If successful, the results of this study will be used to inform the design of a larger, longer trial to confirm the efficacy of vibegron as a novel treatment to IOY1er risk for multisystem functional decline in both aging and obesity.

PROJECT SUMMARY / ABSTRACT This project will improve best practice care delivery and psychosocial outcomes for families of critically ill children hospitalized in the pediatric intensive care unit (PICU). The focus of this proposal is family-centered rounds (FCR), which is recognized as a best practice for hospitalized children. FCR enhances family-centered communication, engagement, understanding of the care plan, and trust in providers. Importantly, these benefits are also strategies to mitigate PICU-related psychosocial harms to family members of the critically ill child. However, FCR is only possible when parents or guardians (“parents” hereafter) can be physically at bedside during rounds. Yet circumstances that prevent physical presence (e.g., work, travel) hinder some families. PICUs lack evidence-based strategies to promote parents’ access to and attendance at FCR. We address this critical gap by testing a telehealth intervention to expand access to and attendance at FCR. We propose a dual cluster randomized trial, which is two simultaneous randomized trials: one testing the intervention of inviting families to use virtual FCR and one testing implementation strategies. Families will be randomized to one of three arms: (1) virtual FCR plus digital navigators (active implementation strategy), (2) virtual FCR plus informative handouts/videos (control implementation strategy), and (3) usual care. In this proposal, we pursue three Specific Aims: Evaluate and compare the impact of providing parents the option of virtual FCR versus usual care on parent FCR attendance, utilization, and psychosocial outcomes (Aim 1). Evaluate and compare two implementation strategies for virtual FCR (Aim 2). Conduct a mixed methods implementation evaluation of the virtual FCR intervention (Aim 3). Aims 1 and 2 will measure heterogeneity of intervention effects and implementation effects, respectively, by pre-specified subgroups. Our team’s preliminary research found that the option to use telehealth to conduct virtual FCR improved parent FCR attendance. All groups benefited from the intervention except for those with the lowest digital literacy and those without a smartphone. We thus build on our prior work to now propose a type 2 hybrid study utilizing the rigorous but underused dual randomized trial design. Our team’s expertise encompasses hospital care delivery interventions, clinical trials, implementation science, community engagement, linguistically appropriate care, mixed methods, and advanced statistics. Our team also includes two patient/provider advisory groups. This application is responsive to NICHD priorities in that it focuses on psychosocial issues related to the care of critically ill children and their families by transforming the delivery of PICU care to be more family- centered and accessible. In summary, this project will advance an innovative FCR solution in the PICU to address families’ unmet needs; and improve parent FCR attendance, healthcare utilization, parent mental health, and sibling well-being.

Project Summary/Abstract To curb the rising rates of suicide, interventions that directly target the causal mechanisms for suicidal behaviors (SB; i.e., suicide capability) are needed. Virtual reality (VR) suicidal decision scenarios are a valid and safe proxy for SB among at-risk individuals and have enabled causal examinations of suicide capability mechanisms. Intriguingly, these studies, including our preliminary data (N = 63), show that exposure to VR suicidal decision scenarios may evoke clinically meaningful reductions in suicide risk via suicide capability mechanisms. These findings converge with mounting evidence for the effectiveness of VR-based exposure in treating numerous psychiatric disorders. We consider a putative suicide capability mechanism that can be safely therapeutically targeted using VR suicidal decision exposure: motivational relevance of the suicidal decision process that facilitates the development of non-threat associations (i.e., inhibitory learning) with suicide ideation (SI) and the reintegration of suicidal deterrents (i.e., negative consequences of SB; reasons for living). This aligns with recent electroencephalography (EEG) findings that suicide attempters, but not ideators, show decreased sustained reactivity to threat/violence, reflecting an ability to volitionally dampen fear-inducing aspects of SI (i.e., suicidal deterrents), temporarily increasing their ability to approach SB. Our pilot EEG data (N = 28 suicidal adults) show VR suicidal decision scenarios engage the target mechanism of motivational relevance. This K23 proposal will evaluate VR suicidal decision exposure as a mechanistic intervention for SB and is designed to make the next critical steps in intervention development: (1) provide preclinical evidence for the feasibility, acceptability, and safety of the intervention in a transdiagnostic sample of 100 adults with recent SI and 50% with a suicide attempt history; (2) test whether the intervention, relative to treatment as usual, effectively engages the proposed mechanistic targets (neural; increases in late-LPP to suicide-related images and fronto-central gamma during the VR decision scenarios) and behavioral indicators (subjective accessibility of suicidal deterrents; behavioral orientation toward death/life) both in lab and in daily life; and (3) test whether change in the mechanistic targets and behavioral indicators account for intervention-associated change in clinical outcomes related to SB. We will use a multi-method approach involving EEG, subjective and behavioral responses, ecological momentary assessment (EMA), and self-reports/interviews to assess changes pre-post the intervention. This K-award addresses crucial gaps in the candidate’s training and will prepare them to be a leader in suicide intervention science employing an experimental therapeutics approach. The candidate will receive advanced training from an expert mentorship team, including mentors Drs. Joiner, Siegle, and Scott and consultants Drs. Patrick and Krafty. Findings will inform future R-level studies focused on 1) intervention refinement and clinical translation and 2) integrative multi-method (neurophysiology, subjective, behavioral, EMA) approaches to further clarify suicide capability mechanisms and develop effective, mechanistically targeted, and scalable SB interventions.

- This funding opportunity announcement (FOA) solicits exploratory/developmental (R21) research grant applications on women's mental health and sex/gender differences in mental health across the lifespan. The epidemiology and disability burden of mental disorders provide clear evidence of the value of a focus on sex differences research. There are differences in both the prevalence and clinical course of mental disorders between men and women. Starting in childhood, girls have higher rates of anxiety disorders than boys. Boys have higher rates of autism and attention deficit disorder. After puberty, women have higher rates than men of depression, eating disorders, and anxiety disorders, including post-traumatic stress disorder. Men are more likely to suffer from substance abuse disorders. For other serious mental disorders, such as schizophrenia and bipolar disorder, gender disparities in incidence are not found. However, significant differences in clinical course have been demonstrated across the lifespan. This pattern of disparities in the epidemiology of mental disorders in males and females provides indirect evidence of genetic, hormonal, biological, social, cultural and developmental factors in etiology and course. An increasing body of basic and clinical research also provides evidence of neurobiological sex differences that may predispose to clinical differences in mental disorders. The finding of sex/gender differences in epidemiological, basic, and clinical studies has also increased interest in the application of that knowledge to improving interventions and services for males and females. In recognition of the importance of studying sex/gender differences in health outcomes, NIH has provided guidelines to researchers for inclusion of women and men in clinical research and for gender analysis of clinical trials outcomes. Through research such as that called for in this FOA, NIMH seeks to increase the understanding of the significance of sex/gender differences in mental health outcomes and to assess their significance for mental health prevention, treatment and services.-This funding opportunity will utilize the R21 mechanism, but will be run in parallel with a program announcement of identical scientific scope that will utilize the traditional research project grant (R01) (PA-06-333).-Because the nature and scope of the proposed research will vary from application to application, it is anticipated that the size and duration of each award will also vary. The total amount awarded and the number of awards will depend upon the mechanism numbers, quality, duration, and costs of the applications received.-The total project period for an application submitted in response to this funding opportunity may not exceed two years. Direct costs are limited to $275,000 over an R21 two-year period, with no more than $200,000 in direct costs allowed in any single year.-Eligible organizations: For profit organizations; Non-profit organizations; Public or private institutions, such as universities, colleges, hospitals and laboratories; Units of State government; Units of local government; Eligible institutions of the Federal government; Domestic institutions; Foreign institutions; Faith-based or community-based organizations; Units of State Tribal government; and Units of Local Tribal government. -Eligible Project Directors/Principal Investigators (PD/PIs): Any individual with the skills, knowledge, and resources necessary to carry out the proposed research is invited to work with their institution to develop an application for support.

PROJECT SUMMARY Hemp-derived intoxicating cannabis products (DICPs), such as Delta-8 THC, THC-A, and THC-P, have rapidly expanded in the U.S. market following the 2018 Farm Bill. Unlike traditional cannabis, DICPs are often sold in unregulated retail settings, making them widely accessible to youth. Despite their recent introduction, DICPs like Delta-8 THC have already achieved substantial levels of youth use. DICP use can pose significant health risks to youth, including intoxication-related accidents, mental health concerns, and cannabis dependence. The growing concern over accidental ingestion and overdose among minors also highlights the urgent need for actions to reduce youth use. While the public health risks of DICP use among youth are increasingly evident, the marketing practices of DICP brands remain largely unexamined. Historically, youth have been highly vulnerable to targeted marketing by tobacco and alcohol industries, which has played a critical role in generating their positive attitudes and intentions toward using these products. DICP brand marketing on social media may further amplify youth’s DICP use interest by leveraging highly engaging visual and interactive features and youth- oriented cultural references. As part of our ongoing research, we identified extensive DICP marketing on youth- popular social media platforms (Instagram, TikTok, and YouTube), characterized by frequent use of vibrant colors, dessert and fruit imagery, cartoon and anime characters, and pop culture references—marketing features well-documented to attract youth and increase product appeal. No research, however, has systematically examined the youth appeal of DICP social media marketing from leading DICP brands. In the absence of concrete evidence on the extent and tactics by which the DICP industry employs youth-appealing marketing on social media, and its behavioral influence among youth, protective policies will remain reactive and vulnerable to legal challenges. Generating this evidence is therefore critical not only to inform and strengthen policy development but also to support and defend existing regulations against industry opposition. To address this, the proposed project will systematically identify and assess youth-appealing marketing features in social media by leading DICP brands over two years (Aim 1) and examine the associations between the presence of youth- appealing marketing features and DICP use intentions and positive marketing engagement among youth (Aim 2). Our multidisciplinary team of accomplished investigators, with demonstrated expertise in relevant domains, is well-positioned to implement the proposed research, ensuring a high degree of scientific rigor and feasibility. Findings from this project will inform actionable, policy-focused strategies to curb youth-appealing social media marketing by leading DICP brands, enhance regulatory oversight of the industry’s marketing practices, and guide social media platforms in limiting youth exposure to DICP marketing content. The proposed project will establish a foundation for ongoing surveillance of DICP marketing on social media and support a sustained research program examining its behavioral impacts on youth.

Emotional and behavioral health (EBH) during the transition from adolescence to young adulthood is critical to long-term health and wellbeing. When EBH is compromised, it places young people at risk for mental health and substance use disorders and other chronic health conditions into adulthood. Adults in the community, including police officers, play an influential role in youth development and EBH. In urban areas of the United States (US), interactions between police and community members are commonplace, and a large portion involve youth and young adults. Young people may have varied responses to these interactions depending on their type and situational features (e.g., whether the interaction is direct or vicarious). Recent data suggests youth-police interactions and their features are tied to adolescents’ psychosocial functioning (e.g., executive functioning, self-regulation). Moreover, psychosocial functioning has been linked to EBH during the transition from adolescence to young adulthood. Yet how youth-police interactions and their features relate to young adult EBH — and the role of psychosocial functioning as a developmental pathway — remains unclear. Informed by the biopsychosocial framework and developmental psychopathology, the proposed R01 will use a convergent parallel mixed methods design to examine associations between youth-police interactions and young adult EBH, focusing on a viable developmental pathway via psychosocial functioning and the role of external protective factors. We will employ data from the Future of Families and Child Wellbeing Study (FFCWS), a longitudinal birth cohort study of young people across 20 urban US areas (N=2,990). In Aim 1, we will examine associations between youth-police interactions and young adult EBH outcomes (emotional wellness, mental and behavioral health problems, substance use; Aim 1a), and test psychosocial functioning as a mediating developmental pathway (Aim 1b), assessing situational features of youth-police interactions as moderators throughout. In Aim 2, we will evaluate how external protective factors (e.g., teacher support, caregiver-child relationships, neighborhood collective efficacy) moderate associations between youth-police interactions and EBH. In Aim 3, we will conduct life history interviews with 120 young adults (ages 18-24) in urban areas across three states reporting direct or vicarious police interactions to explore how these experiences, their situational features, psychosocial functioning, and protective factors relate to EBH (Aim 3a), and integrate quantitative and qualitative findings to generate data-informed recommendation for improving young adult EBH (Aim 3b). EBH is foundational to health across the lifespan. The EBH of young adults in urban areas who report youth-police interactions remains understudied despite widespread police presence in these settings. Study goals reflect NICHD's scientific priorities of improving adolescent health during the transition to adulthood, elucidating developmental mechanisms tied to health outcomes, and identifying protective factors that promote resilience and EBH across the life course.
