Obsessive-compulsive disorder (OCD) is a chronic, serious psychiatric disorder that affects 2%-3% of the population and is associated with high personal and societal costs. Genetic factors are estimated to explain roughly half the risk of developing OCD, and genomic studies are just beginning to identify common and rare genetic variants mediating this risk. A major goal of genomic studies is to yield insights into the etiology of OCD and identify molecular targets for the development of novel therapeutics. However, the overwhelming majority of subjects in existing genetic studies are of European ancestry, limiting the generalizability of these findings. To address …

Breast Cancer-Derived Extracellular Vesicle Mir-425-5p (Mir-425) Promotes Brain Metastasis Via Activating Astrocytes Through The Novel Mir-425-Znf24-Ccl8 Signaling Axis, Grace L Wong, Munazza S Khan, Sara Manore, Shivani Bindal, Ravi Singh, Hui-Wen Lo

Faculty, Staff and Student Publications

Mechanisms underlying breast cancer brain metastasis (BCBM) are still not well understood. Here, we identified that BCBM patient serum contained extracellular vesicles (EVs) with high levels of microRNAs (miRNAs)-107 and -425. Levels of miR-107 and miR-425 were elevated in brain metastases, and the elevation was associated with poor patient prognoses. Ectopic expression of miR-107 and miR-425 promoted mammospheres; however, the inhibition of miR-425, but not miR-107, suppressed breast cancer mammosphere formation. We further observed that EVs from miR-425-overexpressing breast cancer cells strongly activated astrocytes whereas their inhibitors abrogated the effect. Conditioned media from miR-425-activated astrocytes promoted mammospheres. To elucidate how …

RATIONALE: Older patients hospitalized for acute decompensated heart failure with preserved ejection fraction (HFpEF) experience persistently poor outcomes, including physical disability, cognitive impairment, depression, impaired health-related quality of life (HRQOL), rehospitalizations, loss of independence, and mortality. In our previous phase 2 REHAB-HF trial, an innovative physical rehabilitation intervention, delivered across three phases-inpatient, 12-week outpatient, and 3-month home-based maintenance-produced large improvements in physical function and HRQOL, with signals of reduced clinical events among patients with acute HFpEF. These findings provide a compelling rationale for a definitive, event-powered trial to evaluate clinical outcomes.

HYPOTHESIS: Targeting physical frailty and multisystem functional impairments using …

Associations Between Caregiver-Provider Communication Quality And Unmet Care Needs Among Older Adults, Jiaming Liang, Rafael Samper-Ternent, Brian Downer, Zhigang Xie

Faculty, Staff and Student Publications

BACKGROUND: Unmet care needs (lack of assistance with daily activities) among older adults are common and linked to adverse health outcomes, greater healthcare utilization, and caregiver burden. While effective patient-provider communication is known to improve care quality, less is understood about the role of caregiver-provider communication, particularly across sociodemographic, health, and caregiving contexts. METHODS: We conducted a cross-sectional secondary analysis of pooled 2021–2023 National Health and Aging Trends Study (NHATS) and National Study of Caregiving (NSOC) data, restricted to community-dwelling older adults (65 + years) who received assistance from caregivers due to difficulty with daily activities, and had at least …

Cerebellar ataxias are characterized by impaired motor coordination resulting from neuronal dysfunction within the cerebellum. The mechanisms underlying this pathology and its cerebellar-specific neurodegeneration remain unknown. We uncover how a gain-of-function canonical transient receptor potential member 3 (TRPC3) mutation, coupled with a cerebellum-specific isoform, stabilizes the channel’s open state, resists the leading inhibitor Pyr3, and drives calcium-dependent cell death. Restoring calcium homeostasis by expressing a Purkinje cell calcium pump improves cell viability. Transgenic expression of the TRPC3 hypermorphic variant in Caenorhabditis elegans induces neurodegeneration, confirming its pathogenicity across species. Cryo–electron microscopy and molecular simulations reveal the structural basis for the …

Objectives: Despite practice guidelines recommending hormonal testing for all cases of incidentally discovered adrenal adenomas (incidentalomas), only 30% of patients receive laboratory workup. This study sought to evaluate hormonal testing and adrenal surgery rates in incidentaloma patients seen by a specialist (endocrinologist, nephrologist, urologist, or general surgeon), compared to those not seen by a specialist.

Methods: We identified incidentaloma cases by querying the TriNetX Research Network for all adult patients with an unspecified adrenal mass occurring within 1 month following abdominal imaging. We compared those seen by a specialist against those not following an incidentaloma diagnosis. Primary outcomes were rates …

Measurable Residual Disease Testing In Acute Myeloid Leukemia: Current State, Foundational Models, And Tools For Future Development, Joseph Van Galen, Stephen D. Willis, Ashish Bains, Sara H. Small

Department of Medical Oncology Faculty Papers

Acute myeloid leukemia (AML) is a lethal and rapidly progressive hematologic malignancy with high rates of relapse and treatment refractoriness. Management of AML is complicated by biological heterogeneity in a disease that is broadly defined by the clonal expansion of myeloblasts that otherwise play an important role in healthy marrow tissues. While subtypes of AML are increasingly defined by druggable driver mutations including FLT3-ITD, IDH1, IDH2, and NPM1, conventional chemotherapy and reduced intensity induction regimens (e.g., azacitidine-venetoclax) remain therapeutic backbones. One area of active development for personalization of AML treatment is the assessment of measurable residual disease (MRD). MRD testing …

Perceived Partner Substance Use, Genetic Predispositions, And Their Associations With Problematic Alcohol Use, Emotional Well-Being, And Relationship Quality, Megan E Cooke, Kathleen K Bucholz, Vivia V. Mccutcheon, Et Al.

2020-Current year OA Pubs

BACKGROUND: Romantic relationships are important contexts for substance use and emotional well-being. We tested the hypotheses that (i) genetic predispositions for alcohol consumption would be positively associated with partner substance use, (ii) partner substance use would moderate genetic influences on one's own alcohol outcomes, and (iii) partner discordance in substance use would be associated with lower emotional well-being and relationship quality.

METHODS: Analyses included 2,357 participants (M

RESULTS: Participant PGS

CONCLUSIONS: The results highlight the importance of partner substance use in etiological models of alcohol use, emotional health outcomes, and relationship quality.

Tulane Virus Protease As A Structural Surrogate For Inhibitor Screening Of Human Norovirus Proteases, Son Pham, Nikhil Sharma, Banumathi Sankaran, Jalen Nguyen, Mary K Estes, Joseph M Hyser, B V Venkataram Prasad

Faculty, Staff and Students Publications

Human norovirus (HuNoV) is a significant cause of gastroenteritis worldwide, affecting people of all age groups. There are currently no vaccines or drugs available, leaving susceptible populations vulnerable to severe or protracted illness. A HuNoV cultivation system is pivotal for screening norovirus antivirals. While the human intestinal enteroid cultivation system allows robust replication of multiple HuNoV strains, it presents technical and cost barriers. Tulane virus (TV), a surrogate for HuNoV, replicates well in monkey kidney cell lines and is closely related to norovirus in cellular biology. Here, we determined the structures of TV protease (TV-Pro) alone and in complex with …

Γδ T Cells At The Interface Of Innate And Adaptive Immunity In Cancer, Arnau Solé Casaramona, Martin F Bachmann, Eva Sevick-Muraca, Mona O Mohsen

The Brown Foundation: Institute of Molecular Medicine

γδ T cells are unconventional lymphocytes that bridge innate and adaptive immunity by combining recognition of stress-induced ligands independently of classical major histocompatibility complex molecules with the capacity to undergo clonal expansion and long-term adaptation. Their unusual ability to detect malignant transformation using semi-invariant T-cell receptors, butyrophilin recognition and natural killer-like receptors positions them as powerful effector cells in tumors that evade classical immune escape mechanisms. Furthermore, distinct γδ subsets have distinct phenotyping and specific tissue-residencies, which could be leveraged to modulate immunological responses. We evaluate engineered therapies and different experimental platforms for studying γδ T cell biology. We conclude …

Jefferson Center for Connected Care Faculty Papers

BACKGROUND: Transitions of care are high-risk periods for patient safety in the emergency department (ED), particularly for patients who are still in the diagnostic process and are discharged with diagnostic uncertainty. Care transitions must be improved for these patients, as one third of discharged ED patients have diagnostic uncertainty. Yet there are no validated measures that assess the quality of care transitions from the ED, limiting the ability to assess the impact of interventions. Thus, we developed and validated the ED Transitions (EDT) measure.

METHODS: This mixed methods study was conducted across a large healthcare system in three phases: item …

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

INTRODUCTION: FDA-approved chimeric antigen receptor (CAR)-expressing T cell therapies (CARTs) have revolutionized the treatment of blood cancers. Yet none have been successful for "solid" tumors, such as colorectal cancer (CRC), the 2nd leading cause of cancer deaths. Guanylyl cyclase C (GUCY2C) has emerged as a clinical-stage target for CART and bispecific T-cell engager (BiTE) therapies in CRC. IFNγ has been canonically recognized as beneficial for the effector functions of T cells by enhancing antigen processing and HLA presentation and is essential for CART targeting of solid malignancies by inducing adhesion molecule expression for synapse stabilization.

METHODS: Using

RESULTS: We identified …

Pathogen Characteristics Are Key Determinants Of Distinct Host Response Phenotypes Of Sepsis, Rishi Chanderraj, Sunny S. Lou, Et Al.

2020-Current year OA Pubs

BACKGROUNDSepsis encompasses considerable biological and clinical heterogeneity. Previously, 2 phenotypes ("hyperinflammatory" and "hypoinflammatory") have been consistently identified within sepsis via latent class analysis. These phenotypes differ in their biological features, clinical outcomes, and therapeutic responses to interventions. Prior studies of sepsis heterogeneity have focused primarily on the host response. Here, we investigate the potential influence of the causative pathogen on sepsis heterogeneity and pathobiology.METHODSWe performed a retrospective observational analysis of 8,280 critically ill patients with sepsis to identify associations between pathogen characteristics and the hyperinflammatory and hypoinflammatory patient phenotypes. We also performed controlled murine and swine modeling of sepsis and …

In the United States, annual influenza vaccination has been recommended for all persons aged ≥6 months, including during the 2025-26 season. Interim influenza vaccine effectiveness (VE) estimates were calculated for patients with acute respiratory illness-associated outpatient visits and hospitalizations from three U.S. respiratory virus VE networks during the 2025-26 influenza season, using a test-negative case-control design. Among children and adolescents aged < 18 years, VE was 38%-41% against influenza outpatient visits and 41% against influenza-associated hospitalization. Among adults aged ≥18 years, VE was 22%-34% against influenza outpatient visits and 30% against influenza-associated hospitalization. Among children and adolescents, VE against influenza A ranged from 37% (against outpatient visits) to 42% (against hospitalization) across settings; among adults, VE against influenza A ranged from 30% (against hospitalization) to 34% (against outpatient visits) across settings. Among children and adolescents, VE against influenza A(H3N2)-associated outpatient visits was 35% and against influenza A(H3N2)-associated hospitalization was 38%. VE against influenza B outpatient visits ranged from 45%-71% among children and adolescents and was 63% among adults. Other estimates of VE were not statistically significant or were not reportable. Although interim influenza VE is lower during the 2025-26 influenza season than it was during recent influenza seasons, these findings demonstrate that influenza vaccination still provides protection against influenza. CDC recommends influenza vaccination; U.S. influenza vaccines remain available for persons aged ≥6 months.
