Adolescent major depressive disorder (MDD) is a prevalent and serious mental health condition. Pharmacological treatments are commonly used but often have poor tolerability and severe side effects, such as suicidal ideation. Deep transcranial magnetic stimulation (TMS) is currently cleared treating MDD in individuals 22-86 years old. This post-marketing surveillance study was designed to evaluate the safety and efficacy of using this tool as a treatment for MDD in younger patients. Data were collected from 56 sites, resulting in 1257 patients that met inclusion criteria (e.g. 11-21 years old, H1 coil, 18 Hz or iTBS, treatment-resistant MDD). Treatment was well tolerated …

Using functional magnetic resonance imaging (fMRI), symptoms of posttraumatic stress disorder (PTSD) have been associated with aberrations in brain networks in the absence of a given cognitive demand or task, called resting-state networks. Prior work has focused on disruption in the static functional connectivity (FC) among specific regions constrained by a priori hypotheses. However, dynamic FC, an approach that examines brain network characteristics over time, may provide a more sensitive measure to understand the network properties underlying dysfunction in PTSD. Further, using a data-driven analytic approach may reveal the contribution of other larger network disturbances beyond those revealed by hypothesis-driven …

Metabolic reprogramming is a key focus of targeted therapies in acute myeloid leukemia (AML). The mitochondrial sirtuin SIRT5 removes succinyl groups from specific lysines and impacts cell metabolism, but its role in AML tumorigenesis has not been extensively explored. A recent study highlighted that SIRT5 regulates AML cell activity by modulating glutamine metabolism, but its molecular targets in AML remain unclear. This study aims to identify the substrates of SIRT5 in AML. It was found that a total of 83 proteins with 121 lysine (K) residues showed increased succinylation after SIRT5 knockdown, as determined by succinylome analysis of MOLM-13 cells. …

Lineage switch (LS), defined as the immunophenotypic transformation of acute leukemia, has emerged as a mechanism of relapse after antigen-targeted immunotherapy, which is associated with dismal outcomes. Through an international collaborative effort, we identified cases of LS after a host of antigen-targeted therapies (eg, CD19, CD22, CD38, and CD7), described how LS was diagnosed, reviewed treatment approaches, and analyzed overall outcomes for this form of postimmunotherapy relapse. Collectively, 75 cases of LS were evaluated, including 53 (70.7%) cases of B-cell acute lymphoblastic leukemia (B-ALL) transforming to acute myeloid leukemia (AML), 17 (22.7%) cases of B-ALL transforming to mixed phenotypic acute …

Staff and Researcher Publications

Background: Latinx students in the United States can face stressors and structural inequities that can lead to poor academic and mental health outcomes. They comprise 76% of the English Language Learner (ELL) population, yet little is known about the relationship between ELL status and traumatic stress and resilience outcomes among these Latinx students. We sought to see if resilience differs between ELL vs. non-ELL Latinx students, and if traumatic stress risk modifies the association between ELL designation and resilience among Latinx students to inform culturally relevant school resilience interventions and school-wide approaches for this population.

Methods: We analyzed deidentified school …

Research on the neural basis of major depressive disorder suggests that it is fundamentally a disease of cortical disinhibition, where breakdowns of inhibitory neuronal systems lead to diminished emotion regulation and intrusive rumination. Subregions of the prefrontal cortex are thought to be sources of this disinhibition. However, due to limited opportunities for intracranial recordings from humans with major depression, this hypothesis has not been directly tested. Here, we use intracranial recordings from the dorsolateral prefrontal, orbitofrontal, and anterior cingulate cortices from patients with major depression to measure daily fluctuations in self-reported depression symptom severity. Results indicate that directed connectivity within …

Background/Objectives: Dopamine partial agonists are drugs initially developed to treat schizophrenia, seeking a double effect of increased dopaminergic transmission in the prefrontal cortex and decrease in the accumbens/striatum. Of these drugs, aripiprazole, brexpiprazole, and cariprazine are currently marketed and used in schizophrenia spectrum and mood disorders. It is debated whether patients with psychiatric disorders becoming pregnant should discontinue or continue their antipsychotic treatment despite some risks for the fetus, i.e., whether it is worse to have an untreated disorder or treating it with drugs. The safety of drugs for mother and baby extend from pregnancy to the postpartum, when …

Depression, anxiety, and perceived stress are common comorbidities in patients with inflammatory bowel disease (IBD) and may negatively influence the disease course. Likewise, severe IBD may contribute to the development or worsening of psychiatric symptoms. Despite the established relevance of the gut-brain axis and frequent use of psychotropic medications in IBD patients, limited evidence exists regarding the effects of psychiatric treatments on gastrointestinal disease activity. Therefore, the aim of this systematic review is to evaluate the effectiveness of psychiatric therapies on gastrointestinal symptoms and disease activity in patients with IBD. The work was conducted in accordance with PRISMA guidelines. Searches …

Schizophrenia (SCZ) is a complex psychiatric disorder with unclear biological mechanisms. Spectrins, cytoskeletal proteins linked to neurodevelopmental disorders, are regulated by the AKT/GSK3 pathway, which is implicated in SCZ. However, the impact of SCZ-related dysregulation of this pathway on spectrin expression and distribution remains unexplored. Here, we show that βIV spectrin protein levels were reduced in neurons of the dorsolateral prefrontal cortex in SCZ postmortem samples compared to healthy control (HC) from the Human Brain Collection Core (HBCC). To investigate potential links between βIV spectrin and the AKT/GSK3 pathway, we analyzed the PsychEncode dataset, revealing elevated SPTBN4 and AKT2 mRNA …

Background/Objectives: Lurasidone ((3aR,4S,7R,7aS)-2-{(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)piperazin-1-ylmethyl]cyclohexylmethyl}hexahydro-4,7-methano-2H-isoindole-1,3-dione) is a second-generation antipsychotic approved for schizophrenia and mood disorders. Adolescents and children with bipolar disorder receive treatments that expose them to weight gain and metabolic syndrome. Lurasidone is relatively free from such side effects, so it may constitute a useful alternative for the treatment of these patients. We focused on the use of lurasidone in children and adolescents with bipolar disorder.

Methods: On 11 June 2025, we used the following strategy on PubMed: lurasidone AND ("bipolar disorder" OR "bipolar depression" OR mania OR manic). We filtered for humans and ages 0-18 years and included …

Faculty, Staff and Student Publications

Introduction: Understanding predictors of smoking cessation medication efficacy facilitates the ability to enhance treatment effectiveness. In our pilot trial, exenatide, a glucagon-like peptide-1 receptor agonist, adjunct to nicotine patch improved smoking abstinence compared to nicotine patch alone. This secondary analysis explores potential baseline characteristics associated with differential treatment response to exenatide.

Aims and methods: The parent trial randomized (1:1) 84 smokers with prediabetes and/or overweight to once-weekly placebo or exenatide, 2 mg, subcutaneously. All participants received nicotine patch (21 mg) and brief smoking cessation counseling, with biologically confirmed 7-day point prevalence abstinence at week 6 (end-of-treatment) deemed the primary outcome. …

Faculty, Staff and Student Publications

Background: Alcohol, tobacco, and cannabis are the most commonly used substances among young populations, often leading to polysubstance use, which correlates with problematic consumption and adverse health outcomes. The contextualized reinforcer pathology (CRP) model explains addictive behaviors through several constructs, including the following: drug demand, delay discounting (DD), and substance-free and substance-related reinforcement. Most previous studies have focused on a single CRP construct and the couse of only two substances. This study aimed to characterize three subgroups of young adults reporting past month use of alcohol only, alcohol + tobacco or cannabis, and alcohol + tobacco + cannabis, in terms …

Background: Suicide is a prominent cause of death across the lifespan, especially between 10 and 34 years old. Most suicides are first attempts, during crises with unpredictably fluctuating risk, arising insidiously from mechanisms related to long-term exposure to psycho-bio-social risk factors. Identifying susceptibility from interacting immediate and long-term mechanisms of action regulation could prevent suicidal crises.

Methods: We investigated interacting immediate and long-term regulation of action in risk for suicide. Immediate processes were assessed through affective and behavioral symptoms and a computer measure of impaired action-regulation, the Immediate Memory Task (IMT). Long-term processes included history of trauma, stress, and addictive …

Childhood trauma exposure is associated with posttraumatic stress symptoms (PTSS) and suicidality, however it is also a risk factor for obsessive-compulsive disorder (OCD) in adults. Research examining the relationship between childhood trauma and OCD in youth is mixed, and there is a dearth of research examining the associations among OCD, PTSS, and suicidality. As a result, conclusions have been drawn from primarily cross-sectional adult samples. No study has examined the clinical characteristics associated with OCD in trauma-exposed youth, nor its associations with PTSS and suicidality over time. To address this gap, the present study used logistic regressions and generalized estimating …

Background: Black and Hispanic women in the United States continue to bear disproportionate incidence of HIV related to sexual transmission and injection drug use. Specifically, women with substance use disorders (SUDs) are more likely to engage in vaginal or anal condomless sex associated with HIV transmission. Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention tool but is not widely used by racial or ethnic minority women. Effective interventions for engaging women with SUDs in HIV prevention interventions that are culturally appropriate and, therefore, more appealing to racial or ethnic minority women with SUDs are critically needed.

Detailed social determinants of health (SDoH) is often buried within clinical text in EHRs. Most current NLP efforts for SDoH have limitations, investigating limited factors, deriving data from a single institution, using specific patient cohorts/note types, with reduced focus on generalizability. We aim to address these issues by creating cross-institutional corpora and developing and evaluating the generalizability of classification models, including large language models (LLMs), for detecting SDoH factors using data from four institutions. Clinical notes were annotated with 21 SDoH factors at two levels: level 1 (SDoH factors only) and level 2 (SDoH factors and associated values). Compared to …

Genetic, Transcriptomic, And Epigenomic Insights Into Sjögren's Disease: An Integrative Network Investigation And Immune Diseases Comparison, Nitesh Enduru, Astrid M Manuel, Zhongming Zhao

Faculty, Staff and Student Publications

Sjögren's disease (SjD) is a systemic autoimmune disorder primarily causing dry eyes and mouth. It frequently overlaps with other autoimmune diseases (AIDs), including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, the genetic basis of SjD remains underexplored, limiting our understanding of its connections to other immune-mediated conditions. In this study, we aimed to identify gene networks associated with SjD through the integration of genetic, transcriptomic, and epigenomic data. We further compared the genetic factors of SjD with other immune-mediated diseases. We analyzed genome-wide association studies (GWAS) summary statistics, DNA methylation, and transcriptomic data using our in-house network-based methods, …

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3-95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

Neuroimaging-Based Variability In Subtyping Biomarkers For Psychiatric Heterogeneity, Zhenfu Wen, Mira Z Hammoud, Carole E Siegel, Eugene M Laska, Duna Abu-Amara, Amit Etkin, Mohammed R Milad, Charles R Marmar

Faculty, Staff and Student Publications

Neuroimaging-based subtyping is increasingly used to explain heterogeneity in psychiatric disorders. However, the clinical utility of these subtyping efforts remains unclear, and replication has been challenging. Here we examined how the choice of neuroimaging measures influences the derivation of neuro-subtypes and the consequences for clinical delineation. On a clinically heterogeneous dataset (total n = 566) that included controls (n = 268) and cases (n = 298) of psychiatric conditions, including individuals diagnosed with post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), and comorbidity of both (PTSD&TBI), we identified neuro-subtypes among the cases using either structural, resting-state, or task-based measures.

Advanced maternal age (AMA) is defined as a pregnancy in a woman older than 35 years of age. AMA increases the risk for both maternal and neonatal complications, including miscarriage and stillbirth. AMA has also been linked to neurodevelopmental and neuropsychiatric disorders in the offspring. Recent studies have found that age-associated compositional shifts in the gut microbiota contribute to altered microbial metabolism and enhanced inflammation in the host. We investigated the specific contribution of the maternal microbiome on pregnancy outcomes and offspring behavior by recolonizing young female mice with aged female microbiome prior to pregnancy. We discovered that pre-pregnancy colonization …
