Faculty, Staff and Students Publications

Objective: Although both osteoarthritis (OA) and rheumatoid arthritis (RA) can necessitate total knee arthroplasty (TKA), their mechanisms and radiographic patterns of joint space narrowing (JSN) differ. Deep learning (DL) enables compartment-specific measurement of minimum joint space width (mJSW). This study compared JSN patterns between patients with RA and OA undergoing TKA and evaluated the associations between mJSW and RA disease activity.

Methods: In this retrospective study, 409 patients with RA undergoing TKA (2000-2021) were age- and sex-matched with OA patients. A validated DL model quantified medial and lateral mJSW from anteroposterior knee radiographs at 2 timepoints: early (> 2 years …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Calcineurin inhibitors (CNIs) revolutionized kidney transplantation by reducing acute rejection rates. Identical twin kidney transplantation is the only setting in which the allograft is immunologically indistinguishable from self, yet CNI use persists. We characterized CNI utilization across end-stage kidney disease etiologies and examined whether CNI exposure was associated with reduced rejection or improved death-censored graft survival (DCGS).

METHODS: We performed a retrospective cohort study using scientific registry of transplant recipients data (January 2000-August 2025). Among 255 adult identical twin kidney transplant recipients, discharge regimens were categorized by CNI use; Firth penalized Cox regression was the primary method for 10-year …

Large-scale multiancestry genome-wide association studies have identified hundreds of loci associated with type 2 diabetes (T2D) and glycemic traits, yet imputed genotyping arrays limit the detection of low-frequency and rare variants. Whole-genome sequencing (WGS) offers a more complete view of genetic variation, especially across diverse populations. We analyzed high-coverage (38×) WGS data from 21,913 T2D case subjects, 61,036 control subjects, and up to 50,011 individuals with no diabetes with fasting glucose, fasting insulin, and HbA1c from the National Heart, Lung, and Blood Institute Trans-Omics for Precision Medicine Program. We performed single-variant association testing, conditional analysis, fine-mapping, and Bayesian colocalization to …

Extracellular matrix (ECM) dysregulation plays a significant role in the development of intervertebral disc disease (IVDD). The ECM around the chondrocytes in the nucleus pulposus (NP) is unique in that it contains ColVI. While linked to chondrocyte proliferation in cartilage, ColVI's specific role in IVD degeneration is less clear. Our aim was to determine the expression of ColVI in NP cells from degenerative IVDs, along with the effects of soluble ColVI on NP cells. Thus, we compared the expression levels of ColVI in human degenerated IVD samples, along with the effect of soluble ColVI on primary human NP cells. A …

High-Order Brain Interactions During Ketamine-Induced State Changes: A Functional Marker Of Response In Late-Life Treatment-Resistant Depression?, Brittany O'Brien, Rahul Balakrishnan, Sanjay J Mathew, Nicholas Murphy

Faculty, Staff and Students Publications

Ketamine is a fast-acting intervention for treatment-resistant depression (TRD), yet only a subset of patients show robust clinical response, and the underlying neural mechanisms remain unclear. High-order interactions (HOI) derived from multivariate information theory provide a framework for examining nonlinear dependencies among brain regions beyond pairwise connectivity. One such metric, the O-information, captures the balance between synergistic and redundant interactions across three or more variables. In this secondary analysis of a randomized, double-blind, midazolam-controlled trial (NCT02556606), we examined EEG-derived HOI in 30 late-life veterans with TRD following a single 40-minute intravenous infusion of ketamine (0.1, 0.25, 0.5 mg/kg; n = …

OBJECTIVE: Determine whether mismatch repair (MMR) and p53 expression predict recurrence-free survival (RFS) and overall survival (OS) in early-stage endometrial cancer (EC) patients treated with vaginal cuff brachytherapy plus chemotherapy (VCB/C) versus pelvic radiation therapy (RT).

METHODS: In the GOG-0249 trial, 601 patients with high-intermediate risk (HIR) early-stage EC were randomized to VCB/C (carboplatin/paclitaxel for 3 cycles) or pelvic RT. Molecular subgroups, deficient MMR (dMMR), p53 wildtype (p53wt), p53 abnormal (p53abn), were determined by immunohistochemistry. Five-year RFS and OS were analyzed using Kaplan-Meier curves and Cox proportional hazards models, adjusting for lymphadenectomy, planned VCB, and treatment group.

RESULTS: Among 315 …

Objectives: While maxillary sinus fungal balls (MSFB) can be associated with odontogenic conditions (MSFBO), MSFBO clinical and dental features have not been compared to odontogenic sinusitis (ODS). This multicenter study aimed to compare characteristics of MSFB, MSFBO, and ODS.

Methods: A multicenter international retrospective cohort study was conducted on adults with MSFBs and ODS who underwent sinus surgery. First in MSFBs, it was determined whether different dental conditions were more likely in FB versus non-FB sides. Second, clinical features and dental pathologies were compared between MSFBO and ODS. For analyses, dental conditions were considered individually and as two groups: infectious …

Background: Necator americanus glutathione S-transferase-1 (Na-GST-1) performs a crucial enzymatic step in hookworm blood feeding and is a leading target for vaccine development. Phase 1 trials in Brazil, Gabon, and the USA of recombinant Na-GST-1 adsorbed on Alhydrogel (Na-GST-1/Al), co-administered with or without AP 10-701 (Toll-like receptor [TLR] 4 agonist) or CpG 10104 (TLR9 agonist), showed the vaccine was well tolerated, safe, and immunogenic. A controlled human hookworm infection (CHHI) model was previously developed to evaluate the effect of candidate hookworm vaccines on infection. We aimed to assess the effect of vaccination with three different Na-GST-1 vaccine formulations on subsequent …

BACKGROUND: Measurement of donor-derived cell-free DNA fraction (dd-cfDNA%) and donor quantity score (DQS) is a noninvasive biomarker of acute rejection in heart transplantation (HT). Its prognostic value beyond histopathology remains uncertain.

OBJECTIVES: This study sought to evaluate associations between donor-derived cell-free DNA (dd-cfDNA) and clinically meaningful outcomes using a composite endpoint of treated rejection, graft dysfunction, retransplantation, or death within 1 year post-HT.

METHODS: The DEFINE-HT (Development of Noninvasive Cell-free DNA to Supplant Invasive Biopsy in Heart Transplantation) was a prospective, observational study following adult HT recipients at 10 U.S. centers for 1-year post-HT; blood was collected for dd-cfDNA testing …

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disease with diverse prognosis. The underlying mechanisms remain unknown, resulting in limited risk stratification and therapeutic strategies. This study aimed to elucidate molecular subtypes of HCM through integrated proteogenomic analysis and explore subtype-specific therapeutic strategies.

METHODS: We conducted an integrated proteogenomic analysis of 132 patients with HCM using myocardial samples, incorporating whole-exome sequencing, RNA sequencing, and proteomics. Unsupervised clustering was used to identify HCM subtypes, which were validated in heart tissues and human induced pluripotent stem cell-derived cardiomyocytes from 2 independent HCM subsets. Subtype-specific signatures and pathways were explored, and their causal link …

Total energy expenditure (TEE) is commonly modelled as the sum of resting energy expenditure (REE), activity energy expenditure (AEE), and diet-induced thermogenesis (DIT). This additive model has recently been challenged by the constrained energy balance model, which proposes that reductions in mass-adjusted REE compensate to some extent for increases in AEE, rendering mass-adjusted TEE effectively invariant. We tested these competing models using two complementary approaches. First, we conducted a short-term longitudinal, repeated-measures experiment in 12 adults who completed 10-day periods of high and low physical activity separated by a washout period. TEE was measured with doubly labelled water, AEE with …

Purpose: Racial and ethnic differences in oral cavity cancer (OCC) stage at diagnosis are substantial, but the reasons remain unclear. We assessed insurance status and social neighborhood factors as potential pathways.

Methods: Using the Texas Cancer Registry, we identified adults diagnosed with OCC between 2010 and 2020. We examined the crude and multivariable associations of race and ethnicity, insurance status, and social neighborhood factors with stage at diagnosis. We investigated the mediating effects of insurance status and neighborhood-level social factors on racial and ethnic differences in stage at diagnosis using four-way decomposition with modified Poisson regression and robust standard errors. …

Background: Interpretation of urine buprenorphine and norbuprenorphine concentrations is widely used to assess adherence during treatment for opioid use disorder. However, the relationships between dose, timing of sample collection, and metabolite ratios remain unclear, leading to potential misinterpretation in clinical practice.

Methods: Data were collected from patients on a psychiatry unit who were either inducted on or continued buprenorphine therapy and underwent urine testing for buprenorphine and its metabolite, norbuprenorphine. Urine samples were collected 16 to 786 min after the last buprenorphine dose. Norbuprenorphine-to-buprenorphine ratios were calculated. Data analysis using Python included polynomial regression and random forest models.

Results: Daily …
