Association Between Ultraprocessed Food Consumption And Cardiovascular Disease Risk: Mesa (Multiethnic Study Of Atherosclerosis), Amier Haidar, Rishi Rikhi, Karol E Watson, Alexis C Wood, Michael D Shapiro

Children’s Nutrition Research Center Staff Publications

Background: Ultraprocessed foods (UPFs) have been linked to adverse cardiometabolic outcomes and increased atherosclerotic cardiovascular disease (CVD) (ASCVD) risk. However, prior research has largely focused on homogenous populations, lacking racial and ethnic diversity.

Objectives: The objectives are to examine the longitudinal relationship between UPF consumption and ASCVD risk and to investigate whether these associations differ by race/ethnicity, sex, or socioeconomic status.

Methods: The MESA (Multiethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 U.S. adults aged 45 to 84 years, without clinically apparent CVD. UPF consumption was classified according to the Nova classification system. Multivariable cox proportional hazards …

Background: Cardiorespiratory fitness is an integrative measure of cardiometabolic health and predictor of survival, yet little is known about its molecular underpinnings. Small molecule metabolites and lipids are increasingly recognized as exercise-stimulated signaling molecules and candidate molecular transducers of cardiorespiratory fitness.

Methods: We performed nontargeted liquid chromatography mass spectrometry-based plasma metabolomics in 654 participants (mean age, 35 years; 55% women) from the HERITAGE Family Study (Health, Risk Factors, Exercise Training, and Genetics) who had cardiorespiratory fitness (maximal oxygen uptake [VO2max]) measured by cardiopulmonary exercise testing and underwent 20 weeks of supervised endurance training. Metabolite-VO2max relationships were assessed using linear regression …

Beatriz Currier, Raymond Baser, Katherine Panageas, Jodi Macleod, Desiree Walker, Susan Q. Li, Ana Maria Lopez, Kelly Mcconnell, Jun J. Mao

Department of Medical Oncology Faculty Papers

PURPOSE: Anxiety is prevalent, disruptive, and undertreated among survivors of cancer. Cognitive behavioral therapy (CBT) is the first-line treatment, but not all individuals have access, respond to treatment, or prefer this option because of stigma. Music therapy is effective for short-term anxiety reduction, but it is unknown whether it is noninferior to first-line CBT for long-term anxiety reduction.

METHODS: This comparative effectiveness trial randomly assigned English- or Spanish-speaking survivors of cancer to seven weekly telehealth sessions of music therapy or CBT. The coprimary end points were changes in the Hospital Anxiety and Depression Scale (HADS) anxiety score at weeks 8 …

Inhibition Of Gpx4 Induces The Death Of P53-Mutant Triple-Negative Breast Cancer Cells, William M Tahaney, Amanda Lanier, Jing Qian, Cassandra L Moyer, Nghi Nguyen, Yanxia Ma, Jamal Hill, Reid T Powell, Clifford C Stephan, Peter J A Davies, Abhijit Mazumdar, Powel H Brown

Faculty, Staff and Student Publications

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by high rates of tumor protein 53 (TP53) mutation and with limited targeted therapies. Despite being clinically advantageous, direct targeting of mutant TP53 has been challenging. Therefore, we hypothesized that p53-mutant TNBC cells rely upon other potentially targetable survival pathways.

Methods: In vitro and in silico screens were used to identify drugs that induced preferential death in TP53-mutant cells. The effect of the ferroptosis inducer ML-162 was tested both in vitro and in vivo and the mechanism of cell death following ML-162 treatment or GPX4 knockout was …

Peripheral Nerve Injury Reduces Macrophage Efferocytosis To Facilitate Neuropathic Pain, Vipul K Pandey, Tusar K Acharya, Kendal F Willcox, Sandeep Dembla, Ajeena Ramanujan, Anamaria R Grieco, Younus A Zuberi, Rajasekaran Mahalingam, Andrew J Shepherd, Cobi J Heijnen, Peter M Grace

Faculty, Staff and Student Publications

For reasons not fully understood, proresolving immune processes sometimes fail to engage after peripheral nerve injury (PNI), leading to enhanced neuropathic pain and inflammation. Here, we implicate reduced efferocytosis due to proteolytic cleavage of surface MER tyrosine kinase (MERTK) from macrophages at the site of PNI. After PNI, the proportion of macrophages expressing MERTK progressively decreased, while soluble (cleaved) MER increased. Using male and female knock-in mice encoding cleavage-resistant Mertk, we demonstrated that cleavage of MERTK from macrophages at the PNI site led to exaggerated pain-related behaviors. PNI-induced hyperactivity of TRPV1+ sensory neurons and damage to myelin and myelinated …

Vascular endothelial cadherin (VE-Cadherin) is a major endothelial adhesion molecule and can be cleaved explicitly by metalloproteinase domain-containing protein 10 (ADAM10). Vascular hyperpermeability may contribute to a greater susceptibility to sepsis in left ventricular assist device (LVAD) support patients. We aim to evaluate the efficacy of VE-Cadherin and ADAM10 for predicting sepsis in LVAD patients. We prospectively recruited 50 patients with advanced heart failure receiving LVAD therapy. Baseline and weekly postoperative blood samples (weeks 1-4) were collected, and plasma VE-cadherin and ADAM10 levels were measured. Sepsis occurred in 9 of 50 patients (18.0%). Across all sampling points, plasma VE-cadherin and …

Pathological heterogeneity is increasingly appreciated in Alzheimer’s disease, yet we do not know how distinct aggregate conformations arise or influence cognitive outcomes. In an amyloid mouse model, we found that different brain regions formed structurally distinct Aβ deposits, prompting us to test whether neuronal subtypes shape aggregate conformation. To address this, we created transgenic mice expressing the same APP construct in either glutamatergic or GABAergic neurons. APP expression in GABAergic neurons resulted in diffuse plaques with high Aβ42/Aβ40 ratios and minimal gliosis, while glutamatergic expression produced neuritic plaques with activated glia. Despite similar Aβ levels, only mice with neuritic plaques …

Rapid Inpatient Methadone Induction In The Fentanyl Era: A Systematic Review Of Safety, Efficacy, And Protocols For Hospitalized Patients With Opioid Use Disorder, Lorik Berisha, Sapan Patel, Charlotte Pirquet, Navina Magesh Kumar, Yousef Soliman, Ahsan Ullah, Daniel M. Matassa

Division of Internal Medicine Faculty Papers & Presentations

Purpose of Review: The potency of illicit fentanyl has rendered standard methadone inductions inadequate for many hospitalized adults with opioid use disorder. Standard protocols often fail to achieve therapeutic doses quickly enough to manage withdrawal and cravings in fentanyl-tolerant individuals, contributing to poor retention and higher self-discharge rates. This review examines emerging evidence on dosing strategies, outcomes, and safety of rapid methadone inductions in acute-care hospitals. Recent Findings: Nine studies (five retrospective cohorts, four case series/reports) encompassing 380 patients met inclusion criteria. Median starting doses were 30–40 mg (range 20–90 mg), with daily or symptom-triggered increases achieving 60–100 mg within …

Journal of the Saudi Heart Association

Background: Atherosclerosis is the leading underlying cause of cardiovascular disease (CVD), which remains the primary cause of mortality in Saudi Arabia. Saudi patients experience CVD events nearly a decade earlier than their Western counterparts. Given the limitations of traditional risk assessment tools, there is a growing need to detect subclinical atherosclerosis to refine risk stratification and improve primary prevention strategies, particularly in younger and asymptomatic individuals.

Methods: The Saudi Heart Association (SHA) developed this position statement through a structured, multistep process that included a comprehensive literature review and two expert panel meetings. Recommendations were formulated based on current evidence, expert …

Pathogenesis Of Polyglutamine Diseases: Piecing Together A Complex Molecular Puzzle, Esmeralda Villavicencio Gonzalez, Huda Y Zoghbi

Duncan NRI Faculty and Staff Publications

Polyglutamine (polyQ) diseases, caused by a CAG repeat expansion encoding a glutamine tract in nine distinct proteins, present a complex molecular puzzle in which each piece contributes to neurodegeneration. While each of the causative proteins has a distinct function, the downstream consequences of polyQ toxicity are often similar, including protein accumulation, transcriptional dysregulation, somatic CAG repeat instability, disrupted energy homeostasis, compromised synaptic function, and selective neuronal death. This review summarizes emerging insights into how proteins with an expanded polyQ tract disrupt distinct cellular functions, and we examine a multitude of discoveries that are inspiring and reshaping novel therapeutic strategies.

Interactions among tumor, immune, and vascular niches play major roles in glioblastoma (GBM) malignancy and treatment responses. The composition and heterogeneity of extracellular core matrix proteins (CMPs) that mediate such interactions are not well understood. Here, we present an analysis of the clinical relevance of CMP expression in GBM at bulk, single-cell, and spatial anatomical resolution. We show that CMP enrichment is associated with worse patient survival, specific driver oncogenic alterations, mesenchymal state, pro-tumor immune infiltration, and immune checkpoint expression. Matrisome expression is enriched in vascular and leading edge/infiltrative niches that are known to harbor glioma stem cells. Finally, we …

The stimulator of interferon genes (STING) pathway plays a crucial role in immune responses and has emerged as a compelling target in cancer therapy. Despite promising preclinical studies, clinical trials of STING agonists have largely failed to deliver durable efficacy, with no agents progressing to phase III trials. This review examines the biological, pharmacological, and clinical barriers limiting STING pathway activation in cancer treatment. We discuss the inherent limitations of STING agonists as well as host-related resistance driven by tumor heterogeneity, immune suppression, and chronic STING activation. Mechanisms of acquired resistance, such as immune checkpoint upregulation and suppression of effector …

Sequence alignment is essential for genomic research and clinical diagnostics, yet detecting complex rearrangements such as inversions, duplications, and gene conversions remains challenging due to allele complexity and limitations of current methods. We introduce VACmap, a non-linear mapping approach to enhance the detection and representation of all genetic variations. VACmap improves duplication detection from 20% to 90% in the Challenging Medically-Relevant Genes (CMRG) benchmark and improves characterization of complex inversions in repetitive regions and gene conversion events. It improves resolving clinically significant loci, including the LPA gene (with repetitive KIV-2 units linked to coronary heart disease), GBA1 and STRC genes …

Prostate cancer (PCa) is a common malignancy in men worldwide, with incidence projected to rise in the coming years. Traditional screening and diagnostic methods, such as prostate-specific antigen (PSA) testing and biopsy, face limitations in specificity and invasiveness. Circulating microRNAs (miRNAs) have emerged as stable, non-invasive biomarkers obtainable via liquid biopsies (blood, urine, semen) that could transform PCa management. These small regulatory RNAs reflect underlying tumor biology and are detectable at early disease stages, enabling improved early detection when used alongside or in place of PSA. Distinct miRNA expression patterns correlate with tumor aggressiveness. For example, miR-141 and miR-375 are …

Women diagnosed with metastatic triple negative breast cancer (mTNBC) have limited treatment options, are more prone to develop resistance and are associated with high mortality. A cold tumor immune microenvironment (TIME) characterized by low T cells and high tumor associated macrophages (TAMs) in mTNBC is associated with the failure of standard-of-care chemotherapy and immune checkpoint blockade (ICB) treatment. We demonstrate that the combination of immunomodulatory low-dose Cyclophosphamide (CTX) coupled with anti-CSF-1R antibody targeted therapy (SNDX-ms6352) and anti-PD-1 (ICB), was highly effective against aggressive metastatic Trp53 null TNBC transplantable syngeneic models that present with high macrophage infiltration.
