Hepatocellular carcinoma (HCC) mortality is increasing globally, partly due to the growing prevalence of nonviral liver diseases. Genome-wide association studies (GWAS) have identified genetic variants associated with HCC development. Leveraging GWAS summary statistics and linkage disequilibrium score regression (LDSR), we investigated disease co-development with hepatitis C virus-negative (HCV-negative) HCC to provide unique insights into HCC etiology and prioritize relationships for further causal inquiry. We utilized the LDSR statistical framework to estimate the genetic correlation and heritability between HCV-negative HCC with 901 epidemiologic, behavioral, and clinical traits from the United Kingdom Biobank (UKBB). First, we set the threshold for observed scale …

Frontotemporal Network Interactions Causally Support Rapid Concreteness Judgments During Reading, Elliot Murphy, Oscar Woolnough, Cale W Morse, Xavier Scherschligt, Nitin Tandon

Faculty, Staff and Student Publications

Neurobiological models of conceptual processing have been limited in spatiotemporal resolution, and uncertainty remains about the causal role of specific regions in concept representation. We utilized intracranial recordings in human neurosurgical patients with epilepsy (n = 19) during a concreteness judgement paradigm of single word reading. Concrete concepts showed greater high-frequency activation across a frontal and ventrotemporal network, while greater activation for abstract words was found in lateral posterior middle temporal cortex. Intercortical communications, measured by high-frequency partial direct coherence, revealed bidirectional frontal and ventral plus lateral temporal interactions. Words occupying the middle range of the concreteness scale (e.g., "profit") …

Major depressive disorder (MDD) is a complex psychiatric disorder that affects the lives of hundreds of millions of individuals around the globe. Even today, researchers debate if morphological alterations in the brain are linked to MDD, likely due to the heterogeneity of this disorder. The application of deep learning tools to neuroimaging data, capable of capturing complex non-linear patterns, has the potential to provide diagnostic and predictive biomarkers for MDD. However, previous attempts to demarcate MDD patients and healthy controls (HC) based on segmented cortical features via linear machine learning approaches have reported low accuracies. In this study, we used …

Polyploid giant cancer cells (PGCCs), characterised by multinucleation and atypical nuclear morphology, are a common feature of undifferentiated pleomorphic sarcomas. While PGCCs may be a critical substrate for cancer evolution, their formation pathways and genomic consequences remain underexplored. In this study, we characterise PGCCs in ten pleomorphic sarcomas and use topographic single-cell DNA sequencing (scDNA-seq) to investigate their genomic landscape. We selected PGCCs based on their nuclear morphology, including mononucleated or multinucleated bizarre, misshapen nuclei, and analysed them at single-cell resolution. Histopathological analysis showed that PGCCs were often randomly distributed throughout the tumour and did not appear in clusters, suggesting …

Central nervous system (CNS)-hemophagocytic lymphohistiocytosis (HLH) can mimic other neuroinflammatory disorders (ONID), often leading to misdiagnosis. Current diagnostic studies do not reliably distinguish CNS-HLH from ONID. We hypothesized that novel cerebrospinal fluid (CSF) biomarkers identified using unbiased proteomic analysis can facilitate diagnosis of CNS-HLH from ONID. Banked CSF samples were categorized into 3 groups, CNS-HLH, ONID, and controls without CNS inflammation. Proteomic analysis was performed on 25 samples per group (total N = 75). Proteins demonstrating significant changes (>1.5-fold higher and P< .05) in the CNS-HLH compared with ONID and associated with HLH pathophysiology were selected as candidate biomarkers. Cross-platform validation of candidate biomarkers, along with known biomarkers CXCL9 and osteopontin, was performed using enzyme-linked immunosorbent assay (ELISA). One hundred twenty-two proteins were identified on CSF proteomic analysis at 99% confidence. Of these, 10 proteins demonstrated a >1.5-fold change with a P< .05 in CNS-HLH compared with ONID. SerpinG1, lysozyme, and CD14 were selected as candidate biomarkers. ELISA confirmed significant elevation of all 5 biomarkers in CNS-HLH relative to ONID. Median SerpinG1 levels were1242.9 ng/mL in CNS-HLH vs 292.2 ng/mL in ONID (P ≤ .001), lysozyme 222.2 ng/mL vs 65.6 ng/mL (P = .001), and CD14 180.3 ng/mL vs 64.5 ng/mL (P ≤ .001). Median CXCL9 levels were 223.7 ng/mL in CNS-HLH vs 15.5 ng/mL in ONID (P ≤ .001), and osteopontin levels were 356.5 ng/mL vs 92.9 ng/mL (P = .001). These findings demonstrate that novel CSF biomarkers SerpinG1, lysozyme, CD14, and CXCL9 can facilitate diagnosis of CNS-HLH from ONID.

Prognostic risk categorization aids treatment selection for patients with acute myeloid leukemia (AML). Although the European LeukemiaNet (ELN) classifications (2017 and 2022) for AML have been used to stratify outcomes for patients receiving intensive chemotherapy, their application to patients receiving less intensive therapy, such as azacitidine plus venetoclax, has been less satisfactory. In response, a 4-gene classifier that stratifies older patients with AML unfit for intensive chemotherapy into those with higher benefit (wild type), intermediate benefit (FLT3-internal tandem duplication [ITD] or NRAS/KRAS mutation), or lower benefit (TP53 mutation) after azacitidine plus venetoclax treatment was developed. We hypothesized that this 4-gene …

Patients received bevacizumab biweekly plus temsirolimus weekly in a 3 + 3 design to assess safety, maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs). Exploratory analyses included tumor genomic profiling and dynamic contrast-enhanced MRI (DCE-MRI).

Results: Patients had a median age of 59 and median four prior therapies. Common tumor types were ovarian (27%) and head and neck (15%). Treatment-related adverse events occurred in 93.8%, with 31.3% ≥grade …

Two Faces Of Mitral Stenosis: Uncovering Structural And Hemodynamic Signatures Of Rheumatic And Mitral Annular Calcification-Induced Disease, Mohammad S. Hashemi, Peter Abdelmaseeh, Atif Nehvi, Gregg S. Pressman, Arash Kheradvar

BACKGROUND: Mitral annular calcification (MAC) is common and associated with increased cardiovascular risk and, when severe, mitral stenosis (MS). MAC-related MS differs anatomically and hemodynamically from rheumatic MS (RMS), challenging standard diagnostic methods. This study compares structural and flow characteristics, including  kinetic energy losses, across MAC-related MS, RMS, and normal mitral valves, and evaluates the applicability of conventional diagnostic metrics in MAC.

METHODS: Three-dimensional transesophageal echocardiographic data sets from 70 patients (22 normal mitral valves, 26 RMS valves, 22 MAC valves) were used to obtain linear, area, and volumetric measurements for valve comparison. Representative valves from each group were converted …

Women's Preferences For Home-Based Self-Sampling Or Clinic-Based Testing For Cervical Cancer Screening, Joël Fokom Domgue, Monalisa Chandra, Olajumoke Oladoyin, Manali Desai, Robert Yu, Sanjay Shete

Faculty, Staff and Student Publications

Importance: While home-based self-sampling for cervical cancer screening is an evidence-based strategy proven to increase screening access and uptake, it is not currently recommended in the US despite recent Food and Drug Administration approval of the first at-home self-sampling device. Little nationally representative research has examined preference for and drivers of home-based self-sampling over clinic-based testing (the standard of care).

Objective: To assess women's perspectives about, reasons for considering, and factors associated with preferring at-home self-sampling for cervical cancer screening.

Design, setting, and participants: This population-based cross-sectional study used data from the 2024 Health Interview National Trends Survey (HINTS 7), …

Objectives: Participant retention is essential in prospective studies to minimize bias and maintain validity. This study aimed to estimate retention rates and identify factors influencing attrition in a multicenter cohort (PROCEED) of US adults with acute/recurrent acute pancreatitis (AP/RAP) and chronic pancreatitis (CP).

Methods: Participants from the PROCEED study with AP/RAP or CP eligible for follow-up within the designated visit window were included. Retention was defined as completing at least one follow-up visit during the observation period. Retention was analyzed by follow-up mode (in-person and/or medical record review) and disease type (AP/RAP and CP). Retention factors were assessed using univariate …

Objectives: Candida species are one of the most common causes of ICU-onset bloodstream infection (BSI). Yet, there is no robust guidance on when to initiate empiric antifungals for ICU patients suspected of BSI. We compared patients with ICU-onset candidemia vs. ICU-onset bacteremia to determine which patients may benefit from empiric antifungals.

Design: We compared characteristics between patients with bacteremia vs. candidemia at time of culture. We determined risk factors for death and constructed a multivariable regression to determine if candidemia is an independent risk factor for death.

Setting/patients: We included ICU patients from a hospital system in Houston, Texas (n …
