Perceived Neighborhood Crime And Gun Carrying Behavior: Examining The Role Of A History Of Traumatic Brain Injury, Eric J Connolly, Anne C Wingert, Dennis E Reidy, Jarrad D Hodge, Jeff R Temple

Faculty, Staff and Student Publications

Background: Individuals living in high crime neighborhoods are more likely to carry a firearm. Members of these communities are also more likely to experience a traumatic brain injury (TBI) in their lifetime, which is a common correlate of hypervigilance and aggression. The current study evaluates the independent and interactive effects of TBI on perceived levels of neighborhood crime and gun carrying.

Methods: Data from 2015 to 2017 from a longitudinal ethnically diverse sample of adolescents and young adults are analyzed (Ns = 600-734). Multivariate logistic regression models are estimated to evaluate associations between perceived levels of neighborhood crime, TBI, gun …

Assessment Of Contextualized Reinforcement Pathology In A Community Sample Of Young Adult Substance Users, Ángel García-Pérez, Alba González-Roz, Roberto Secades-Villa, Gema Aonso-Diego, Sara Weidberg, Jin H Yoon

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: 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.

Objective: This 3-phased …

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 …

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. The …

Structural and functional alterations in the brain's reward circuitry are present in cocaine use disorder (CocUD), but their molecular underpinnings remain unclear. To investigate these mechanisms, we performed single-nuclei multiome profiling on postmortem caudate nucleus tissue from six individuals with CocUD and eight controls. We profiled 30,030 nuclei, identifying 13 cell types including D1- and D2-medium spiny neurons (MSNs) and glial cells. We observed 1485 differentially regulated genes and 10,342 differentially accessible peaks, with alterations in MSNs and astrocytes related to neurotransmitter activity and synapse organization. Gene regulatory network analysis identified transcription factors including ZEB1 as exhibiting distinct CocUD-specific subclusters, …

Intersect Between Brain Mechanisms Of Conditioned Threat, Active Avoidance, And Reward, Muhammad Badarnee, Zhenfu Wen, Mira Z Hammoud, Paul Glimcher, Christopher K Cain, Mohammed R Milad

Faculty, Staff and Student Publications

Active avoidance is a core behavior for human coping, and its excess is common across psychiatric diseases. The decision to actively avoid a threat is influenced by cost and reward. Yet, threat, avoidance, and reward have been studied in silos. We discuss behavioral and brain circuits of active avoidance and the interactions with fear and threat. In addition, we present a neural toggle switch model enabling fear-to-anxiety transition and approaching reward vs. avoiding harm decision. To fully comprehend how threat, active avoidance, and reward intersect, it is paramount to develop one shared experimental approach across phenomena and behaviors, which will …

Suicide Phenotyping From Clinical Notes In Safety-Net Psychiatric Hospital Using Multi-Label Classification With Pre-Trained Language Models, Zehan Li, Yan Hu, Scott Lane, Salih Selek, Lokesh Shahani, Rodrigo Machado-Vieira, Jair Soares, Hua Xu, Hongfang Liu, Ming Huang

Faculty, Staff and Student Publications

Accurate identification and categorization of suicidal events can yield better suicide precautions, reducing operational burden, and improving care quality in high-acuity psychiatric settings. Pre-trained language models offer promise for identifying suicidality from unstructured clinical narratives. We evaluated the performance of four BERT-based models using two fine-tuning strategies (multiple single-label and single multi-label) for detecting coexisting suicidal events from 500 annotated psychiatric evaluation notes. The notes were labeled for suicidal ideation (SI), suicide attempts (SA), exposure to suicide (ES), and non-suicidal self-injury (NSSI). RoBERTa outperformed other models using binary relevance (acc=0.86, F1=0.78). MentalBERT (F1=0.74) also exceeded BioClinicalBERT (F1=0.72). RoBERTa fine-tuned with …

Evaluating The Emotional Accuracy Of Ai-Generated Facial Expressions In Neurotypical Individuals, Antonio Pagán, Katherine A Loveland, Ronald Acierno

Faculty, Staff and Student Publications

This study examines the ability of generative artificial intelligence to produce facial expressions representing basic emotions in a neutral context using black-and-white cartoon imagery. Mentalization, the capacity to recognize and interpret one’s own and others’ mental states, is critical for social interaction and emotional regulation. We explored the emotional validation of artificial intelligence (AI)-generated images by assessing the agreement between human interpretations of emotions and those generated by an AI model. Thirty-four participants evaluated images depicting six basic emotions: sadness, anger, happiness, surprise, fear, and disgust. Our findings revealed significant variability in human agreement, with higher concordance for sadness, anger, …

Initiation Of Hearing Aids Use And Incident Dementia Among Mid-To-Late Life Adults: The Health And Retirement Study 2010-2018, Jingkai Wei, Kun Li, Youngran Kim, Rahul Ghosal, Donglan Zhang, Anwar T Merchant, Casey Crump

Faculty, Staff and Student Publications

BACKGROUND AND OBJECTIVES: Hearing aids may reduce the risk of dementia among individuals with hearing loss. However, no evidence is available from randomized controlled trials (RCTs) on the effectiveness of hearing aids use in reducing incident dementia. Using target trial emulation, we leveraged an existing longitudinal cohort study to estimate the association between hearing aids initiation and risk of dementia.

RESEARCH DESIGN AND METHODS: The Health and Retirement Study was used to emulate target trials among non-institutionalized participants aged ≥50 years with self-reported hearing loss, without dementia at baseline, and without use of hearing aids in the previous 2 years. …

The blood-brain barrier (BBB) plays a pivotal role in protecting the central nervous system (CNS), and shielding it from potential harmful entities. A natural decline of BBB function with aging has been reported in both animal and human studies, which may contribute to cognitive decline and neurodegenerative disorders. Limited data also suggest that being female may be associated with protective effects on BBB function. Here, we investigated age and sex-dependent trajectories of perfusion and BBB water exchange rate (kw) across the lifespan in 186 cognitively normal participants spanning the ages of 8-92 years old, using a non-invasive diffusion-prepared pseudo-continuous arterial …

Ketamine’S Mechanism Of Action With An Emphasis On Neuroimmune Regulation: Can The Complement System Complement Ketamine’S Antidepressant Effects?, Brandi Quintanilla, Carlos A Zarate, Anilkumar Pillai

Faculty, Staff and Student Publications

Over 300 million people worldwide suffer from major depressive disorder (MDD). Unfortunately, only 30-40% of patients with MDD achieve complete remission after conventional monoamine antidepressant therapy. In recent years, ketamine has revolutionized the treatment of MDD, with its rapid antidepressant effects manifesting within a few hours as opposed to weeks with conventional antidepressants. Many research endeavors have sought to identify ketamine's mechanism of action in mood disorders; while many studies have focused on ketamine's role in glutamatergic modulation, several studies have implicated its role in regulating neuroinflammation. The complement system is an important component of the innate immune response vital …

Shared Delusion: Impact On The Parent-Child Relationship, Ngozi Adaralegbe, Ayotomide Oyelakin, Omobusayo Omotayo

Faculty, Staff and Student Publications

Folie à famille, also known as shared psychotic disorder among family members, is a rare and underdiagnosed psychiatric condition. This disorder, seldom discussed in the literature, is particularly notable for its impact on clinical management and parent-child relationships. The few reported cases have predominantly focused on adult populations, leaving a significant gap in understanding how this condition manifests and affects younger individuals and family dynamics. One area that remains largely unexplored in the literature is the intersection between attachment patterns and shared psychosis, particularly in the context of parent-child relationships. Understanding this intersection is crucial, as it can provide insights …

Reliability And Validity Of The Patient Health Questionnaire-4 Scale And Its Subscales Of Depression And Anxiety Among Us Adults Based On Nativity, David Adzrago, Timothy J Walker, Faustine Williams

Faculty, Staff and Student Publications

BACKGROUND: The burdens of anxiety and depression symptoms have significantly increased in the general US population, especially during this COVID-19 epidemiological crisis. The first step in an effective treatment for anxiety and depression disorders is screening. The Patient Health Questionnaire-4 (PHQ-4, a 4-item measure of anxiety/depression) and its subscales (PHQ-2 [a 2-item measure of depression] and Generalized Anxiety Disorder [GAD-2, a 2-item measure of anxiety]) are brief but effective mass screening instruments for anxiety and depression symptoms in general populations. However, little to no study examined the psychometric properties (i.e., reliability and validity) of the PHQ-4 and its subscales (PHQ-2 …

Biological Aging Markers In Blood And Brain Tissue Indicate Age Acceleration In Alcohol Use Disorder, Lea Zillich, Metin Cetin, Elisabeth M Hummel, Eric Poisel, Gabriel R Fries, Josef Frank, Fabian Streit, Jerome C Foo, Lea Sirignano, Marion M Friske, Bernd Lenz, Sabine Hoffmann, Kristina Adorjan, Falk Kiefer, Georgy Bakalkin, Anita C Hansson, Falk W Lohoff, Olli Kärkkäinen, Eloise Kok, Pekka J Karhunen, Greg T Sutherland, Consuelo Walss-Bass, Rainer Spanagel, Marcella Rietschel, Dirk A Moser, Stephanie H Witt

Faculty, Staff and Student Publications

Background: Alcohol use disorder (AUD) is associated with increased mortality and morbidity risk. A reason for this could be accelerated biological aging, which is strongly influenced by disease processes such as inflammation. As recent studies of AUD show changes in DNA methylation and gene expression in neuroinflammation-related pathways in the brain, biological aging represents a potentially important construct for understanding the adverse effects of substance use disorders. Epigenetic clocks have shown accelerated aging in blood samples from individuals with AUD. However, no systematic evaluation of biological age measures in AUD across different tissues and brain regions has been undertaken.

Nlrp3 Activation Contributes To Memory Impairment In An Experimental Model Of Pneumococcal Meningitis, Jaqueline S Generoso, Cristiano Julio Faller, Allan Collodel, Carlos Henrique Rocha Catalão, Diogo Dominguini, Fabricia Petronilho, Tatiana Barichello, Vijayasree V Giridharan

Faculty, Staff and Student Publications

Bacterial meningitis is considered a life-threatening condition with high mortality rates. In response to the infection, signaling cascades, producing pro-inflammatory mediators trigger an exacerbated host immune response. Another inflammatory pathway occurs through the activation of inflammasomes. Studies highlight the role of the NLR family pyrin domain containing 3 (NLRP3) in central nervous system disorders commonly involved in neuroinflammation. We aimed to investigate the role of NLRP3 and its inhibitor MCC950 on neurochemical, immunological, and behavioral parameters in the early and late stages of experimental pneumococcal meningitis. For this, adult male Wistar rats received an intracisternal injection of Streptococcus pneumoniae or …

Faculty, Staff and Student Publications

Organophosphates (OPs) are found in hundreds of important products used worldwide; however, they have been associated with adverse long-term health consequences ranging from neurodevelopmental deficits to age-related neurological diseases. OP exposure has also been implicated in Gulf War Illness; a cluster of medically unexplained chronic symptoms estimated to affect 25-32% of veterans of the Persian Gulf war in 1991. The development of multiple types of chronic illnesses in these veterans at an early age compared to the general population has led to the suggestion that they are experiencing signs of premature or accelerated aging. The process of cellular senescence and …
