To develop reliable, valid, and efficient measures of obsessive-compulsive disorder (OCD) severity, comorbid depression severity, and total electrical energy delivered (TEED) by deep brain stimulation (DBS), we trained and compared random forests regression models in a clinical trial of participants receiving DBS for refractory OCD. Six participants were recorded during open-ended interviews at pre- and post-surgery baselines and then at 3-month intervals following DBS activation. Ground-truth severity was assessed by clinical interview and self-report. Visual and auditory modalities included facial action units, head and facial landmarks, speech behavior and content, and voice acoustics. Mixed-effects random forest regression with Shapley feature …

Gsk-3Β As A Potential Coordinator Of Anabolic And Catabolic Pathways In Hepatitis C Virus Insulin Resistance, Gokul C Das, F Blaine Hollinger

Faculty, Staff and Students Publications

INTRODUCTION: Chronic hepatitis C infection can result in insulin resistance (IR). We have previously shown that it occurs through the interaction of pathways for glucose homeostasis, insulin signaling, and autophagy. But it is not known how soon the pathways are activated and how IR is related to the signals generated by catabolic and anabolic conditions occurring in infected cells. We have extended our studies to a cell culture system mimicking acute infection and to downstream pathways involving energy-sensor AMPK and nutrient-sensor mTOR that are active in catabolic and anabolic processes within the infected cells.

METHODS: Huh7 liver cells in culture …

Reproductive Factors And Their Association With Physical And Comprehensive Frailty In Middle-Aged And Older Women: A Large-Scale Population-Based Study, Wenting Hao, Qi Wang, Ruihong Yu, Shiva Raj Mishra, Salim S Virani, Nipun Shrestha, Chunying Fu, Dongshan Zhu

Faculty, Staff and Students Publications

Study question: Are women's reproductive factors associated with physical frailty and comprehensive frailty in middle-age and later life?

Summary answer: Early menarche at < 13 years, age at menopause < 45 years, surgical menopause, experiencing miscarriage and a shorter reproductive period of < 35 years were associated with increased odds of frailty, while having two or three children was related to decreased likelihood of frailty.

What is known already: Evidence has shown that women are frailer than men in all age groups and across different populations, although women have longer lifespans. Female-specific reproductive factors may be related to risk of frailty in women.

Study design size duration: A population-based cross-sectional study involved 189 898 women from the UK Biobank.

Steroid Receptor Coactivators In Treg And Th17 Cell Biology And Function, Yosi Gilad, Ortal Shimon, Sang Jun Han, David M Lonard, Bert W O'Malley

Faculty, Staff and Students Publications

Steroid receptor coactivators (SRCs) are master regulators of transcription that play key roles in human physiology and pathology. SRCs are particularly important for the regulation of the immune system with major roles in lymphocyte fate determination and function, macrophage activity, regulation of nuclear factor κB (NF-κB) transcriptional activity and other immune system biology. The three members of the p160 SRC family comprise a network of immune-regulatory proteins that can function independently or act in synergy with each other, and compensate for - or moderate - the activity of other SRCs. Recent evidence indicates that the SRCs are key participants in …

Faculty, Staff and Students Publications

Tissue-resident memory T cells (TRM) are a specialized subset of long-lived memory T cells that reside in peripheral tissues. However, the impact of TRM-related immunosurveillance on the tumor-immune microenvironment (TIME) and tumor progression across various non-small-cell lung cancer (NSCLC) patient populations is yet to be elucidated. Our comprehensive analysis of multiple independent single-cell and bulk RNA-seq datasets of patient NSCLC samples generated reliable, unique TRM signatures, through which we inferred the abundance of TRM in NSCLC. We discovered that TRM abundance is consistently positively correlated with CD4+ T helper 1 cells, M1 macrophages, and resting dendritic cells in the TIME. …

Faculty, Staff and Students Publications

BACKGROUND & AIMS: The protection provided by rotavirus (RV) vaccines is highly heterogeneous among individuals. We hypothesized that microbiota composition might influence RV vaccine efficacy.

METHODS: First, we examined the potential of segmented filamentous bacteria (SFB) colonization to influence RV vaccine efficacy in mice. Next, we probed the influence of human microbiomes on RV vaccination via administering mice fecal microbial transplants (FMTs) from children with robust or minimal RV vaccine responsiveness. Post-FMT, mice were subjected to RV vaccination followed by RV challenge.

RESULTS: SFB colonization induced a phenotype that was reminiscent of RV vaccine failure (ie, failure to generate RV …

Choosing Your “Healthiest” Embryo After Dobbs: Polygenic Screening And Distinctive Challenges For Truth In Advertising And Informed Consent, Dov Fox, Sonia Suter, Meghna Mukherjee, Stacey Pereira, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Polygenic embryo screening ("PES") analyzes embryos for hundreds or thousands of genomic loci to generate risk scores that estimate genetic susceptibility to conditions and traits compared to the general population. The technology is commercially marketed directly to consumers. Companies focus mostly on medical conditions, sometimes in ways that oversell its advantages and efficacy, encouraging fertility patients to "choose your healthiest embryo" and "protect your future child from genetic risks." The advertising of PES trades on norms of children's health and good parenting and reinforces those normative ideals. While it is easy to assume PES will be constrained in practice by …

Study Protocol For Measuring Stigmatization In Persistent Tic Disorders: Development And Validation Of The Tourette Discrimination-Stigmatization Scale, Jaclyn M Martindale, Victor M Ringheanu, Kelly A Pring, Sandra Norona, Kimberly Wiseman, Roy E Strowd, Leah Chapman, Joseph Rigdon, Stephen R Rapp, Eric A Storch, Edward Ip, Jonathan W Mink

Center for Medical Ethics and Health Policy Staff Publications

Introduction: Persistent Tic Disorders such as Tourette Syndrome are common neurodevelopmental disorders that are highly stigmatized. Many individuals with Persistent Tic Disorders experience peer rejection, loneliness, and self-stigma. Experiencing stigmatization during childhood can influence the persistence of moderate-to-severe tics later in life. Additionally, these factors have been associated with increased suicidal ideation, suicide attempts, and psychiatric symptom severity. There is a need for interventions to reduce stigma and stigmatization in Persistent Tic Disorders. Before developing cost-effective interventions to mitigate stigma's profound downstream health impacts, a reliable measure of stigmatization must be created. The overarching goal of this research is to …

Interrogating The Value Of Return Of Results For Diverse Populations: Perspectives From Precision Medicine Researchers, Caitlin E Mcmahon, Nicole Foti, Melanie Jeske, William R Britton, Stephanie M Fullerton, Janet K Shim, Sandra Soo-Jin Lee

Center for Medical Ethics and Health Policy Staff Publications

Background: Over the last decade, the return of results (ROR) in precision medicine research (PMR) has become increasingly routine. Calls for individual rights to research results have extended the "duty to report" from clinically useful genetic information to traits and ancestry results. ROR has thus been reframed as inherently beneficial to research participants, without a needed focus on who benefits and how. This paper addresses this gap, particularly in the context of PMR aimed at increasing participant diversity, by providing investigator and researcher perspectives on and questions about the assumed value of ROR in PMR.

Methods: Semi-structured interviews with a …

Succinic Semialdehyde Dehydrogenase Deficiency: A Metabolic And Genomic Approach To Diagnosis, Kevin E Glinton, Charul Gijavanekar, Abbhirami Rajagopal, Laura P Mackay, Kirt A Martin, Phillip L Pearl, K Michael Gibson, Theresa A Wilson, V Reid Sutton, Sarah H Elsea

Faculty, Staff and Students Publications

Genomic sequencing offers an untargeted, data-driven approach to genetic diagnosis; however, variants of uncertain significance often hinder the diagnostic process. The discovery of rare genomic variants without previously known functional evidence of pathogenicity often results in variants being overlooked as potentially causative, particularly in individuals with undifferentiated phenotypes. Consequently, many neurometabolic conditions, including those in the GABA (gamma-aminobutyric acid) catabolism pathway, are underdiagnosed. Succinic semialdehyde dehydrogenase deficiency (SSADHD, OMIM #271980) is a neurometabolic disorder in the GABA catabolism pathway. The disorder is due to bi-allelic pathogenic variants in

Translational And Oncologic Significance Of Tertiary Lymphoid Structures In Pancreatic Adenocarcinoma, Zachary Gao, Joseph Azar, Huili Zhu, Sophia Williams-Perez, Sung Wook Kang, Celia Marginean, Mark P Rubinstein, Shalini Makawita, Hyun-Sung Lee, E Ramsay Camp

Faculty, Staff and Students Publications

Pancreatic adenocarcinoma (PDAC) is an aggressive tumor with poor survival and limited treatment options. PDAC resistance to immunotherapeutic strategies is multifactorial, but partially owed to an immunosuppressive tumor immune microenvironment (TiME). However, the PDAC TiME is heterogeneous and harbors favorable tumor-infiltrating lymphocyte (TIL) populations. Tertiary lymphoid structures (TLS) are organized aggregates of immune cells that develop within non-lymphoid tissue under chronic inflammation in multiple contexts, including cancers. Our current understanding of their role within the PDAC TiME remains limited; TLS are complex structures with multiple anatomic features such as location, density, and maturity that may impact clinical outcomes such as …

Anomalous Aortic Origin Of A Coronary Artery In Pediatric Patients, Tam T Doan, Charles Puelz, Craig Rusin, Silvana Molossi

Faculty, Staff and Students Publications

PURPOSE OF REVIEW: We present a contemporary approach to risk assessment and management of patients with anomalous aortic origin of a coronary artery (AAOCA).

RECENT FINDINGS: Anomalous left coronary artery from the right aortic sinus (L-AAOCA) with interarterial course carries a high risk of sudden cardiac death (SCD); therefore, current guidelines recommend exercise restriction and surgical intervention. Recent data in intraseptal and juxtacommissural L-AAOCA showed inducible perfusion abnormalities, leading to consideration of surgical intervention. Anomalous right coronary artery from the left aortic sinus (R-AAOCA) carries a much lower risk and stress perfusion imaging is helpful in identifying patients with inducible …
