Background:

While functional connectivity is widely studied, there has been little work studying functional connectivity at different spatial scales. Likewise, the relationship of functional connectivity between spatial scales is unknown.

Methods:

We proposed an independent component analysis (ICA)-based approach to capture information at multiple-model orders (component numbers), and to evaluate functional network connectivity (FNC) both within and between model orders. We evaluated the approach by studying group differences in the context of a study of resting-state functional magnetic resonance imaging (rsfMRI) data collected from schizophrenia (SZ) individuals and healthy controls (HC). The predictive ability of FNC at multiple spatial scales …

Epigenetic Grimage Acceleration And Cognitive Impairment In Bipolar Disorder, Camila N C Lima, Robert Suchting, Giselli Scaini, Valeria A Cuellar, Alexandra Del Favero-Campbell, Consuelo Walss-Bass, Jair C Soares, Joao Quevedo, Gabriel R Fries

Faculty, Staff and Student Publications

Bipolar disorder (BD) has been previously associated with clinical signs of premature aging, including accelerated epigenetic aging in blood and brain, and a steeper age-related decline in cognitive function. However, the clinical drivers and cognitive correlates of epigenetic aging in BD are still unknown. We aimed to investigate the relationship between multiple measures of epigenetic aging acceleration with clinical, functioning, and cognitive outcomes in patients with BD and controls. Blood genome-wide DNA methylation levels were measured in BD patients (n = 153) and matched healthy controls (n = 50) with the Infinium MethylationEPIC BeadChip (Illumina). Epigenetic age estimates were calculated …

Revisiting Sex Differences In The Acquisition And Extinction Of Threat Conditioning In Humans, Zhenfu Wen, Jamie Fried, Edward F Pace-Schott, Sara W Lazar, Mohammed R Milad

Faculty, Staff and Student Publications

Findings pertaining to sex differences in the acquisition and extinction of threat conditioning, a paradigm widely used to study emotional homeostasis, remain inconsistent, particularly in humans. This inconsistency is likely due to multiple factors, one of which is sample size. Here, we pooled functional magnetic resonance imaging (fMRI) and skin conductance response (SCR) data from multiple studies in healthy humans to examine sex differences during threat conditioning, extinction learning, and extinction memory recall. We observed increased functional activation in males, relative to females, in multiple parietal and frontal (medial and lateral) cortical regions during acquisition of threat conditioning and extinction …

Number-Time Interaction: Search For A Common Magnitude System In A Cross-Modal Setting, Anuj Shukla, Raju S Bapi

Faculty, Staff and Student Publications

A theory of magnitude (ATOM) suggests that a generalized magnitude system in the brain processes magnitudes such as space, time, and numbers. Numerous behavioral and neurocognitive studies have provided support to ATOM theory. However, the evidence for common magnitude processing primarily comes from the studies in which numerical and temporal information are presented visually. Our current understanding of such cross-dimensional magnitude interactions is limited to visual modality only. However, it is still unclear whether the ATOM-framework accounts for the integration of cross-modal magnitude information. To examine the cross-modal influence of numerical magnitude on temporal processing of the tone, we conducted …

Identifying Critical Aging Care Challenges And Opportunities In High-Income Countries: A Cross-Country Comparison Of Denmark, Germany, And The United States, Cassandra Martin

Capstone Collection

Despite the rapid growth in the aging population in the United States, insufficient resources and attention are invested in improving the support systems this population relies on. This discussion explored the question of how the United States as a high-income country fails to operate an aging care support infrastructure that has comparable comprehensiveness, availability, affordability, and overall quality to other high-income countries. Comparing financing structures, long-term care models, and various aging care supports is important for answering this question. This paper approached exploring this question by analyzing specified indicators from publicly available data across the United States, Germany, and Denmark. …

No One Should Have To Give Birth Alone: An Analysis Of The Efficacy Of Community-Based Doula Programs Serving Ethnic Minorities In San Francisco, Maria Margaret Nelson

Master's Projects and Capstones

Adverse birth outcomes for both the parent and the child disproportionately affect people of color. Evidence demonstrates that one of the ways to mitigate these negative consequences is through the utilization of a doula, a trained birth companion that is not a medical provider but whose role it is to physically and emotionally support the patient through pregnancy, birth, and postpartum. Community-based doula programs, where the doula is of the same cultural background as the client, are particularly effective in improving birth outcomes in communities of color by providing culturally competent care and helping to navigate a healthcare system that …

Stepped Care Versus Standard Care For Children After Trauma: A Randomized Non-Inferiority Clinical Trial, Alison Salloum, Yuanyuan Lu, Henian Chen, Troy Quast, Judith A Cohen, Michael S Scheeringa, Kristen Salomon, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Objective: Trauma-focused cognitive-behavioral therapy (TF-CBT) is an evidence-based therapist-led treatment for children after trauma. Parents often experience barriers to treatment engagement, including cost. Stepped care TF-CBT (SC-TF-CBT) was developed as an alternative delivery system. Step One is a parent-led therapist-assisted treatment. Step Two provides therapist-led TF-CBT for children who did not benefit from Step One and require more intensive treatment. This study compared SC-TF-CBT to standard TF-CBT in a community-based non-inferiority trial.

Method: A total of 183 children (aged 4-12 years) experiencing posttraumatic stress symptoms (PTSS) and their caregivers were randomly assigned to SC-TF-CBT or standard TF-CBT within 6 community …

Faculty, Staff and Student Publications

Introduction

Stroke, a life-threatening stressor, often negatively impacts stroke-survivor (SS) quality of life (QoL). Annual age-adjusted incidence and death rates for stroke are significantly higher among Black Americans than among White Americans. Racism, a significant stressor, occurs at structural, cultural, and interpersonal levels and contributes to health disparities for Black SS. Resilience, a dynamic process of positive adaptation to significant stress, is impacted by factors or resources both internal and external to the individual. This study aims to examine the effects of experiences of racism and resilience on Black SS QoL during early stroke recovery. This article presents the study …

Faculty, Staff and Student Publications

Depressed individuals are twice as likely to develop Alzheimer’s disease (AD) as compared to controls. Brain amyloid-β (Aβ) deposition is believed to have a major role in AD pathogenesis but studies also suggest associations of Aβ dynamics and depression. The aim of this study was to test if plasma Aβ levels are longitudinally associated to late-life depression. We measured plasma levels of amyloid-β1-40 (Aβ40) and amyloid-β1-42 (Aβ42) peptides longitudinally for three consecutive years in 48 cognitively intact elderly subjects with late-life major depressive disorder (LLMD) and 45 age-matched cognitively healthy controls. We found that the Aβ42/Aβ40 plasma ratio was significantly …

Let's Get Physical: Exploring The Socioemotional Motivators Of Group Exercise For Older Adults, Tessneem S. Hasan, Alyssa R. Minton, Jason Snyder, Joseph A. Mikels

DePaul Discoveries

Approximately 75% of active adults in the U.S. do not meet the recommended levels of overall physical activity (CDC, 2021a). Given the beneficial impact of physical activity on health, an 8-week long, evidence-based group exercise program—Fit & Strong! (F&S!)—was created to improve the health of older adults (Hughes et al., 2004, 2006, 2010). Despite the clear physical benefits of F&S!, it remains unknown what motivates F&S! participants to initially participate in the program and also throughout the program. Drawing from core notions of socioemotional selectivity theory (SST; Carstensen, 2006), research has found that older adults are highly motivated to exercise …
