Fear-based disorders, including anxiety and posttraumatic stress disorder, are more prevalent in females than males. Steroid hormones (e.g., estradiol) are involved in fear extinction learning and later recall—a process implicated in the pathophysiology of fear-based disorders. Fear-based disorders commonly emerge during the transition from childhood to adolescence, a period marked by the onset of puberty and a natural increase of steroid hormones. Here, we examined the effects of puberty, sex, and their interaction on extinction recall and underlying neural circuitry in youth. Eighty-five youth (6-17 years, 46% female) completed a two-day Pavlovian fear extinction paradigm while undergoing functional magnetic resonance …

A Systematic Review Of Digital Technology Use For The Treatment And Management Of Ptsd, Liam Browning, Arash Javanbakht, Imran Rashid

Medical Student Research Symposium

The COVID-19 pandemic led to rapid growth in telemental health services and investment in digital mental health technologies. Digital mental health technologies could expand access to mental health care in a time of increasing provider deficit by providing tools for expedited psychiatric symptom assessment and management. This systematic review explores the current evidence for the use of scalable digital treatment modalities, including virtual reality (VR), machine learning, wearables, mobile apps, and neurofeedback training in the diagnosis and treatment of PTSD. Our findings support the current literature suggesting VR interventions are efficacious for combat-related PTSD treatment and that conclusions of studies …

Furman, Amy Loree Phd, Lyuba Gavrilova Bs, Leah Hecht Phd, Hsueh-Han Yeh, Frances Lynch, Brian Ahmedani, Rebecca Rossom, Anne Beck Phd, Yihe Daida Phd, Gregory Simon Md, Christine Lu Phd, Joslyn Westphal Mph, Ashii Owen-Smith Phd, Stephen Waring, Cathrine Frank Md

Medical Student Research Symposium

Objective: Examine pregnancy-related, demographic, psychosocial and healthcare utilization factors associated with suicide mortality among childbearing-aged women. Methods: Data from nine health care systems in the Mental Health Research Network were included. A case-control study design was used in which 290 childbearing-age women who died by suicide (cases) from 2000-2015 were matched with 2,900 childbearing-age women from the same healthcare system and enrolled during the same time period who did not die by suicide. Conditional logistic regression was used to analyze associations between patient characteristics and suicide. Results: Women who died by suicide were more likely to have mental health or …

Childhood-Onset Attention-Deficit/Hyperactivity Disorder Exacerbates Opioid Use Disorder Consequences: Mediation By Impulsive Phenotypes, Liam R. Browning, Ciara Cannoy, Tabitha E. H. Moses, Leslie H. Lundahl Phd, David M. Ledgerwood Phd, Mark K. Greenwald Phd

Medical Student Research Symposium

Background: Attention deficit hyperactivity disorder (ADHD) is highly prevalent and associated with opioid use disorder (OUD). Yet, little is known about the mechanisms by which ADHD (which is a heterogeneous construct/diagnosis) might alter the trajectory of OUD outcomes.

Aim: This cross-sectional study examines relationships between childhood ADHD (inferred as predating substance use) and the extent to which the effects of ADHD on lifetime heroin-use consequences are mediated by foreshortened time perspective and drug-use impulsivity.

Methods: Individuals who report heroin use (N=214) were screened using the Assessment of Hyperactivity and Attention (AHA), Impulsive Relapse Questionnaire (IRQ), Stanford Time Perception Inventory (STPI), …

Factors Associated With Suicide Mortality Among Childbearing-Aged Individuals: A Case-Control Study, Katerina A. Furman, Amy Loree Phd, Leah Hecht Phd, Katerina Furman Md Candidate, Lyuba Gavrilova Bs, Hsueh-Han Yeh Phd, Catherine Frank Md, Brian Ahmedani Phd

Medical Student Research Symposium

Purpose: Examine pregnancy-related, demographic, psychosocial and healthcare utilization factors among childbearing-aged individuals who were pregnant, postpartum or who experienced pregnancy loss

Methods: Data from nine health care systems in the Mental Health Research Network was included in this sample. A case-control study design was used in which 290 childbearing-age individuals who died by suicide (cases) from 2000-2015 were matched with 10 childbearing-age individuals from the same healthcare system and enrolled during the same time period who did not die by suicide (n=2,900). Conditional logistic regression was used to analyze associations between pregnancy/postpartum/pregnancy loss status and suicide.

Results: …
