Cerebral small vessel disease (cSVD) is a leading cause of stroke and dementia with no specific treatment, of which molecular mechanisms remain poorly understood. To identify potential biomarkers and therapeutic targets, we applied Mendelian randomization to examine over 2,500 proteins measured in plasma and, uniquely, cerebrospinal fluid, in relation to magnetic resonance imaging (MRI) markers of cSVD in more than 40,000 individuals. Here we show that 49 proteins are associated with MRI markers of cSVD, most prominently in cerebrospinal fluid. We highlight associations that are consistent across platforms and ancestries, and supported by complementary observational analyses, and we explore differences …

BACKGROUND AND AIM: Alagille syndrome (ALGS) is a rare disorder characterised by cholestasis and extrahepatic manifestations. Given the current era of ileal bile acid transporter (IBAT) inhibitor therapies that reduce serum bile acid (SBA) levels, we evaluated whether SBA predicts liver disease outcomes in ALGS.

METHODS: Patients were ascertained from the Global ALagille Alliance (GALA) cohort. A prognostic threshold of SBA 102 μmol/L was assessed as a time-dependent covariate in Cox regression analyses for native liver survival (NLS) and event-free survival (EFS), while adjusting for total bilirubin (TB) levels.

RESULTS: 570 GALA patients were included (348 [61%] male). There was …

Composite outcomes included hospitalization, emergency department visit, or urgent care visit within 7 days after the dental visit. Opioid-attributable outcomes included opioid-related overdose within 7 days …

Fam13a Polymorphism Is Associated With A Usual Interstitial Pneumonia Pattern In Patients With Systemic Sclerosis-Associated Interstitial Lung Disease, Elana J Bernstein, Francesco Boin, Brett Elicker, Yiming Luo, Yawen Ren, Meng Zhang, John Varga, Shervin Assassi

Faculty, Staff and Student Publications

Objectives: The MUC5B promoter single nucleotide polymorphism (SNP) rs35705950 has been associated with idiopathic pulmonary fibrosis (IPF) and RA-related interstitial lung disease (ILD), but not with SSc-ILD. We hypothesized that the MUC5B promoter polymorphism or other IPF susceptibility loci are associated with an increased risk for the uncommon SSc-usual interstitial pneumonia (UIP) endophenotype, rather than SSc-ILD in general.

Methods: We performed a cross-sectional study of SSc-ILD patients from four US Scleroderma Programs to investigate the frequency of MUC5B rs35705950 and 12 additional IPF susceptibility loci. SSc-ILD patients were stratified by high resolution chest CT (HRCT) imaging findings into UIP and …

Rationale: There are insufficient data to inform the management of central sleep apnea (CSA) in patients with heart failure with reduced ejection fraction (HFrEF). Nocturnal oxygen therapy (NOT) has been postulated to benefit CSA patients with HFrEF but has not been rigorously studied. Objectives: To compare NOT with sham NOT (control) in heart failure (HF) patients receiving guideline-based HF therapy on the composite outcome of first occurrence of either mortality due to any cause, a lifesaving cardiovascular intervention, or an unplanned hospitalization for worsening HF, together with other secondary outcomes.

Methods: A multisite, double-blind, sham-controlled randomized clinical trial was conducted …

A Urine-Based Point-Of-Care Test For Factor Xa Inhibitors In Acute Stroke Management, Prasen R Marella, Jacob A Sambursky, Kriti Bhayana, Asha P Jacob, Varsha Muddasani, Murli Mishra, Alexandra L Czap, James C Grotta

Faculty, Staff and Student Publications

Background: For stroke patients with history of possible Direct Acting Oral Anticoagulant use, clinicians must make treatment decisions without knowledge of whether the patient is therapeutically anticoagulated. A urine-based point-of-care test might help guide these emergency decisions.

Methods: We prospectively enrolled patients with suspected recent factor-Xa-inhibitor (Xai) use being evaluated for acute stroke therapy in an urban teaching hospital. We obtained the urine test and plasma anti-Xa level in parallel with usual clinical management; the treating clinician did not use test results for decision-making but recorded treatment they would have given had they known the urine test was accurate.

Faculty, Staff and Student Publications

Understanding the effects of reduced frame rates on the reliability of Modified Barium Swallow (MBS) ratings for swallowing safety and efficiency is essential for clinical practice. While previous research has examined frame rate (simulated pulse rates) implications concerning penetration, aspiration, and residue ratings, the impact on summary grading systems like the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) remains unclear. This study analyzed a total of 315 full MBS videos collected from 278 patients, and 76.25% of patients were diagnosed with head and neck cancer (mean age 62.51 years, SD 8.53; 12.23% female). We performed pairwise comparisons of DIGEST grades …

Poor clinical responses to immune checkpoint blockade (ICB) observed in ovarian cancer (OC) highlight an unmet need to understand the mechanisms driving immune evasion in this disease. To address this, an integrative analysis is conducted by combining in vitro genome‐wide immune screens, in vivo ICB screens, and clinical data mining, and METTL5 is identified as a crucial OC‐intrinsic factor that promotes immune resistance. Immunologically “cold” OC tumors and poor responders to ICB exhibit elevated METTL5 expression. Mechanistically, knocking out (KO) METTL5 in OC disrupts ATF4 translation by altering 18S rRNA m6A levels, leading to the downregulation of SLC7A11 and SLC3A2 …

Perceived Utility Of Genetic Carrier Screening In A Diverse Patient Population, Jack A Colleran, Meagan Choates, Syed Hashmi, Brittanie Shelton, Aranza Gonzalez Cendejas, Angela Haynes Burgess, Blair K Stevens

Faculty, Staff and Student Publications

Current reproductive guidelines call for offering expanded carrier screening (ECS) for genetic conditions. Currently available panels can include screening for carrier status of tens to hundreds of autosomal recessive and/or X-linked conditions. Clinical utility is based on alterations to reproductive decision-making, but study cohorts supporting the utility of ECS largely consist of individuals of European ancestry who are highly educated, of high income, and who often receive preconception counseling. There is a lack of research on the views of patients from diverse backgrounds. Therefore, we aimed to assess and compare perceptions of the utility of ECS and targeted carrier screening …

MECOM rearrangements (MECOM-r) are acute myeloid leukaemia (AML)-defining, regardless of blast percentage or MECOM fusion partner. We sought to investigate if blast percentage or MECOM-r partner was associated with overall survival (OS). We included 152 adult patients with newly diagnosed MECOM-r and classified blast percentage into < 20% or ≥20% and MECOM-r partner into classic (GATA2::MECOM) or variant (others). Thirty-one per cent had < 20% blasts, with 69% having ≥20%; 57% had classic and 43% variant MECOM-r. Treatment was with intensive chemotherapy (IC) in 41% and low-intensity therapy (LIT) in 59%. Composite complete remission rates were similar between IC (50%) and LIT (48%, p = 0.99). The median OS was 17 months (95% confidence interval [CI], 12-not estimable [NE]) for < 20% blasts, compared with 9 months (95% CI, 6-10) for ≥20% blasts (p <  0.01). On multivariate analysis, ≥20% blasts were associated with worse OS (hazard ratio [HR] 1.9, [95% CI, 1.2-3.2], p <  0.01), independent of age, MECOM-r partner, additional cytogenetic abnormalities, treatment intensity, addition of venetoclax and stem cell transplant (SCT). HR for IC was 2.0 (95% CI, 1.1-3.7, p = 0.03). In < 20% blasts, variant MECOM-r was independently associated with a reduced hazard of death (HR 0.2 [95% CI, 0.1-0.8], p <  0.01). MECOM-r AML is a heterogenous entity; consideration should be given to LIT approaches.

At more than 200 years, the maximum lifespan of the bowhead whale exceeds that of all other mammals. The bowhead is also the second-largest animal on Earth1, reaching over 80,000 kg. Despite its very large number of cells and long lifespan, the bowhead is not highly cancer-prone, an incongruity termed Peto’s paradox2. Here, to understand the mechanisms that underlie the cancer resistance of the bowhead whale, we examined the number of oncogenic hits required for malignant transformation of whale primary fibroblasts. Unexpectedly, bowhead whale fibroblasts required fewer oncogenic hits to undergo malignant transformation than human fibroblasts. …

Faculty, Staff and Student Publications

Background: Postpartum diagnosis of breast cancer confers increased risk of metastasis and death, possibly because of protumorigenic pathways that occur after weaning. We sought to evaluate the impact of postpartum diagnosis on survival in patients with inflammatory breast cancer (IBC).

Methods: We performed a retrospective analysis of patients with nonmetastatic IBC enrolled in a prospective registry (2007-2023). Kruskal-Wallis, χ2, and Fisher exact tests were used to compare between postpartum groups. The Kaplan-Meier method and log-rank tests were used for survival estimates.

Results: Among 320 patients with IBC, 25 (7.8%) were nulliparous, 31 (9.7%) were 0 to 5 years postpartum, 26 …

Individualizing Nsaid Therapy In Axial Spondyloarthritis: N-Of-1 Trials With Bayesian Analysis, Mark C Hwang, Seokhun Kim, Shervin Assassi, Reyna Chavez, Joyce Samuel, Charles Green, Jon Tyson, John Reveille

Faculty, Staff and Student Publications

Objective: Axial spondyloarthritis (axSpA) is a chronic inflammatory disease predominantly affecting the spine and sacroiliac joints. NSAIDs are first-line therapy, but individual responses vary widely. We evaluated the efficacy and patient preference of three NSAIDs (celecoxib, meloxicam and naproxen) through Bayesian N-of-1 clinical trials to optimize axSpA management.

Methods: We conducted N-of-1 trials with 42 patients meeting ASAS criteria for axSpA. Each patient was asked to complete two cycles of randomized double-blind crossover comparisons of the three NSAIDs, each for 4 weeks. The primary end point was the change in the Ankylosing Spondylitis Disease Activity Score (ASDAS). Bayesian analysis assessed …

Impact Of Propofol Or Sevoflurane On The Renoprotective Effect Of Remote Ischaemic Preconditioning In Cardiac Surgery: The Hypnorenalrip Randomised Clinical Trial, Alexander Zarbock, Ludwig Maximilian Schöne, John A Kellum, Joachim Gerss, Raphael Weiss, Hendrik Booke, Melanie Meersch

Faculty, Staff and Student Publications

Background: Remote ischaemic preconditioning (RIPC) might reduce acute kidney injury after cardiac surgery. Protective effects appear to be restricted to patients with early and transient increases in two cell cycle arrest markers, tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7), in urine. Studies suggest that propofol can attenuate the preconditioning effect on the myocardium. This study investigated whether propofol diminishes the renoprotective effect associated with the early transient increases in TIMP-2 and IGFBP7.

Methods: This was a single-centre, prospective randomised double-blind 2×2 factorial clinical trial of high-risk patients undergoing cardiac surgery. Patients were randomised to receive …

The understanding of how antidepressant (AD) use is associated with brain structure in individuals with major depressive disorder (MDD) remains incomplete. We aimed to examine the association between AD medication use and brain morphology in relation to age and sex by pooling structural neuroimaging and clinical data from 32 cohorts within the ENIGMA-MDD working group. Interaction effects of group (2076 cases with current AD use (AD), 1495 cases not currently taking AD (nAD) and 5125 healthy controls (HC)) with age and sex, and main effects of group on regional brain structure (cortical surface area and thickness, and subcortical volume) were …

Background: Idecabtagene vicleucel (ide-cel) is a BCMA-directed CAR-T associated with high response rates in relapsed/refractory multiple myeloma (RRMM), yet responses are not durable and most patients experience toxicities. Fludarabine (Flu) is a key component of lymphodepletion but exhibits significant pharmacokinetic (PK) variability.

Objective: Given Flu exposure (AUC) predicts outcomes after CD19-directed CAR-T, we hypothesized it would predict outcomes after ide-cel. Our objective was to determine the association between fludarabine AUC and clinical outcomes after standard-of-care (SOC) ide-cel.

Study design: RRMM patients receiving ide-cel from 10 US Multiple Myeloma Immunotherapy Consortium centers were retrospectively analyzed. A population PK approach using cumulative …

Purpose: The entire course of radiation therapy (RT) for high-grade glioma (HGG) is currently derived from pre-RT magnetic resonance imaging (MRI). Although it is possible to adapt RT during the course of treatment, it is often guided only by anatomical changes to the tumor. This study seeks to determine if a biology-based mathematical model, parameterized by patient-specific, multiparametric MRI (mpMRI) data, can accurately forecast HGG response during RT.

Methods and materials: Twenty one patients with HGG planned for 6 weeks of concurrent RT and chemotherapy were imaged weekly with mpMRI during RT and at 1, 2, and 3 months post-RT. …
