Non-Tobacco Nicotine Dependence Is Associated With Increased Complications Following Clavicle Open Reduction Internal Fixation, Akin A. Adio, Rahul K. Goyal, Abby Skiena, Mohammad Daher, John G. Horneff, Hafiz F. Kassam, Brian W. Hill, Joseph A. Abboud

Rothman Institute Papers

BACKGROUND: Tobacco dependence is well established to impair bone healing and increase postoperative complications. However, the independent effects of nicotine, separate from combustion-related factors, remain unclear. This study aimed to evaluate the impact of non-tobacco nicotine dependence (NTND) following open reduction and internal fixation (ORIF) of clavicle fractures, including midshaft and lateral fracture subtypes.

METHODS: A retrospective cohort study was performed using a large national database. Patients undergoing ORIF of clavicle fractures were identified using procedural and diagnostic codes. Patients with non-tobacco nicotine dependence (e.g., vaping, patches, or gum) were identified and propensity score matched to (1) patients without nicotine …

Intrathecal (G4c2)149 Delivery In C9orf72-Deficient Mice Yields Mild Motor Dysfunction And Als/Ftd Pathological Hallmarks, Katelyn Russell, Amelia Shahrabi, Suleyman Akerman, Matthew D. Byrne, Jeffrey Rothstein, Davide Trotti, Brigid Jensen, Aaron Haeusler

Farber Institute for Neuroscience Faculty Papers

A repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), yet existing mouse models incompletely engage spinal regions implicated in disease. Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity …

Division of Rheumatology Faculty Papers

OBJECTIVE: To investigate whether lung microbial composition differs between individuals with rheumatoid arthritis and pulmonary fibrosis (RA-PF) compared to those without fibrosis (RA-no-PF).

METHODS: We enrolled 54 RA patients (22 RA-PF, 32 RA-no-PF) from rheumatology and pulmonary clinics. PF was defined by high-resolution computed tomography (HRCT) findings. Induced sputum was analyzed using 16 S rRNA sequencing to identify the relative abundance of sputum bacteria. Taxonomic differences between groups were evaluated using three independent analytic approaches: Mann-Whitney U, DESeq2, and EdgeR, with false discovery rate correction. Logistic regression examined associations between Lautropia abundance and clinical variables.

RESULTS: Individuals with RA-PF were …

Faculty, Staff and Students Publications

Oncogenic viruses cause high-risk cancers in humans and are responsible for nearly 20% of all cancer cases worldwide. Currently, very limited data exist in the realm of wastewater-based viral epidemiology (WBE) for cancer-causing viruses, with existing studies using targeted approaches (i.e., PCR-based approaches) that lack genomic resolution. In this study, we used a hybrid-capture approach to detect, filter, and sequence all known oncogenic virus signals from wastewater samples collected over 3 years (May 2022-May 2025) in 16 Texas cities, covering nearly 25% of the state's population. Once sequenced, we used custom computational tools designed for wastewater metagenomics to assign reads …

Electronic Health Record Alerts To Improve Lipid Lowering After A Recent Myocardial Infarction, Dean G. Karalis, Benjamin Richter, Scott Hessen, Patrick Moeller, Laney K. Jones

Division of Cardiology Faculty Papers

BACKGROUND: This observational, quality initiative evaluated the impact of changing from a passive (dismissible) to an active (nondismissible without action) electronic health record alert on guideline-recommended lipid-lowering therapy (LLT) prescriptions in patients with recent myocardial infarction at risk for secondary events.

METHODS: We sequentially recruited a retrospective passive-alert (February 2018-July 2019; n=733) and a prospective active-alert (August 2020-January 2022; n=587) cohort of patients who triggered an alert to intensify LLT or order a low-density lipoprotein-cholesterol (LDL-C) test if they had a recent myocardial infarction (within 12 months) and elevated (≥70 mg/dL) or missing LDL-C. Prescribed LLTs and cumulative percentages of …

High-grade gliomas (HGGs) are aggressive brain tumors with poor prognosis, driven in part by metabolic and epigenetic adaptations. Methionine metabolism supports HGG growth by supplying S-adenosylmethionine for methylation reactions, yet how nutrient availability influences chromatin organization in HGG remains incompletely understood. Using an immunocompetent mouse model of HGG, we found that dietary methionine restriction reduced tumor proliferation, extended survival, and induced partial nuclear inversion. We identified Hp1bp3 as a key regulator of tumor growth that functions by interacting with nuclear tethering proteins to mediate chromatin reorganization. Loss of Hp1bp3 results in the upregulation of histone demethylases leading to selective depletion …

Hiv-1 Tat-Driven Glutamate Dysregulation: Implications For Cognitive Impairment In Hand, Brenna Duffy, Michael Nonnemacher, Sandhya Kortagere

Kimmel Cancer Center Faculty Papers

PURPOSE OF REVIEW: HIV-1-associated neurocognitive disorders (HAND) manifest in 15% to 50% of people with HIV, impairing learning and memory and executive function. The chronic generation of HIV-1 Transactivator of transcription (Tat) likely contributes to HAND via direct neuronal toxicity and glial-mediated toxicity. This review summarizes our current understanding of how chronic Tat generation from microglia and astrocytes promote glutamate excitotoxicity.

RECENT FINDINGS: In recent years, the indirect effects of Tat through the activation of glial cells have gained significant interest. This review highlights microglia and astrocytes as HIV-1 reservoirs that release Tat protein in the central nervous system. Specific …

Idiopathic pulmonary fibrosis (IPF) is a devastating chronic lung disorder with limited treatment options. Macropinocytosis is one of the key cellular processes involved in nutrient consumption from the extracellular environment under stress conditions. Here, we studied the role of macropinocytosis in experimental pulmonary fibrosis models. We found that macropinocytosis is increased in human lung fibroblasts (HLFs) derived from patients with IPF. The inhibition of macropinocytosis with 5-(n-ethyl-n-isopropyl)-amiloride (EIPA) inhibited profibrotic responses in IPF-derived and TGF-β1-stimulated HLFs and reduced pulmonary fibrosis in bleomycin-injured (Bleo-injured) mice. EIPA exerted its antifibrotic effects by regulating amino acid uptake, mammalian target of rapamycin complex 1 …

Ultrasound-Enabled Refreshable Electrochemical Sensors For Cardiac Biomarker Monitoring, Mayank Garg, Heng Guo, Myeong Namkoong, Elizabeth Zhanov, Connor Malone, Md Saifur Rahman, Ayse Akcan-Arikan, Limei Tian

Faculty, Staff and Students Publications

Cardiac troponin I (cTnI) is the gold-standard biomarker for acute myocardial infarction, yet current laboratory-based high-sensitivity assays require centralized infrastructure, trained personnel, and serial testing, limiting their suitability for real-time or continuous monitoring in resource-limited settings. Point-of-care electrochemical sensors have shown promise for rapid cTnI detection, but their reliance on antibodies as biorecognition elements and redox mediator solutions, and single-use operation restricts practical translation. Here, we report an ultrasound-enabled refreshable electrochemical biosensor for sensitive, stable, and repeatable cTnI monitoring. The device employs a cTnI-specific peptide as the biorecognition element, providing enhanced stability during storage, transport, and operation. Label-free electrochemical impedance …

Autophagic Flux Blockade Under Hypocapnia Reveals Co2-Sensitive Regulation Of Autophagy-Lysosome Homeostasis, Naghmana Ashraf, Zhen Sun, Jeanine L Van Nostrand

Faculty, Staff and Students Publications

Hypocapnia, a reduction in partial pressure of carbon dioxide (CO2), commonly occurs in clinical contexts such as mechanical ventilation, panic disorder, and brain injury, yet its impact on cellular homeostasis remains poorly understood. Given the central role of autophagy in stress adaptation, we investigated how low CO2 influences autophagic flux and lysosomal function. We found that hypocapnia induces autophagosome accumulation while impairing cargo degradation, indicating a blockade in autophagic flux. This response was accompanied by increased lysosome biogenesis but, paradoxically, reduced autophagosome-lysosome fusion and lysosomal proteolytic activity. Mechanistically, hypocapnia promoted TFE3 dephosphorylation and nuclear translocation, driving transcriptional activation of lysosomal …

Jefferson Center for Connected Care Faculty Papers

BACKGROUND: Patients presenting with bleeding or pelvic pain in early pregnancy are commonly found to have pregnancies of unknown location (PUL), with no sonographic findings of intrauterine nor ectopic pregnancy. We aimed to explore healthcare experiences and needs of patients presenting with PUL.

METHODS: This was a qualitative study using semi-structured interviews to explore healthcare experiences among patients with PUL. Patients were eligible if they presented with bleeding or abdominopelvic pain to the OB/GYN office or emergency department and were found to have a PUL followed in an electronic health record tracking list; had an initial human chorionic gonadotropin (hCG) …

Glycosphingolipids Regulate Phosphatidylserine Transport Machinery That Operates At Er-Pm Contact Sites, Ritchel Gannaban, Sher Ali, Wei Chen, Melanie Nguyen, Li Lai, Travis I Moore, Yubin Zhou, John F Hancock, Junchen Liu

The Brown Foundation: Institute of Molecular Medicine

Plasma membrane (PM) localization of KRAS requires specific glycosphingolipids in the outer leaflet and phosphatidylserine (PS) in the inner leaflet. PM PS content is controlled by lipid transport proteins ORP5 and ORP8, which operate at ER-PM membrane contact sites (MCSs). Using high-resolution imaging, we now show that GSLs, including GM3 and SM4, are required to maintain ORP5 and ORP8 localization to MCSs. Genetic deletion or pharmacologic inhibition of enzymes required for the biosynthesis of GM3 or SM4 displaces PI4-kinase Type IIIα (PI4KIIIα) and its adaptor EFR3A from the PM, thereby reducing PM phosphatidylinositol 4-phosphate (PI4P) content. PM interactions of ORP5 …

Apolipoprotein B100 Predicts Cardiovascular And Limb Events In Type 2 Diabetes Patients With Chronic Limb-Threatening Ischemia, Federico Biscetti, Maria Margherita Rando, Maria Anna Nicolazzi, Flavia Angelini, Roberto Iezzi, Luis H. Eraso, Paul J. Dimuzio, Dario Pitocco, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) and chronic limb-threatening ischemia (CLTI) undergoing lower extremity revascularization (LER) face high risks of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), despite guideline-directed lipid-lowering therapy. Apolipoprotein B100 (ApoB100), reflecting total atherogenic particle number, may identify residual risk beyond LDL-cholesterol (LDL-C). Therefore, we investigated whether baseline ApoB100 levels independently predict MACE and MALE beyond conventional risk factors in this high-risk population.

METHODS: In this prospective cohort study, 167 T2DM patients with CLTI undergoing LER were followed for 12 months with visits at 1, 3, 6, and 12 months post-procedure. …

Cryoneurolysis Of Auriculotemporal Nerve For Treatment Of Otalgia, Nikit Patel, Shireen Rabiei, Daniel Moon, Yevgeniya Sergeyenko

Moss-Magee Rehabilitation Papers

Otalgia in adults is often secondary to non-otologic pathology, particularly with normal otoscopic examination. Auriculotemporal neuralgia (ATN) is a rare and overlooked cause of secondary otalgia. We present a case of an Army veteran with chronic right otalgia and dizziness following blast-related mild traumatic brain injury who was initially diagnosed with vestibular migraine. Despite significant improvement in headache symptoms with migraine-directed preventive and abortive treatments, otalgia persisted. Auriculotemporal nerve block produced complete but short-lived pain relief, confirming ATN. Cryoneurolysis of the auriculotemporal nerve resulted in complete resolution of otalgia for 2-3 months after first and second treatments. However, transient worsening …

High Mobility Group Motif Proteins’ Role In Fibrosis, Inflammation, And Vascular Injury In Systemic Sclerosis, Fabian A. Mendoza, Sonsoles Piera-Velazquez, Sergio A. Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

Systemic Sclerosis (SSc) is an idiopathic systemic autoimmune disease characterized by progressive cutaneous and systemic fibrosis, severe vasculopathy, and multiple humoral and cellular immunological alterations. The pathogenesis of SSc is highly complex and remains incompletely elucidated. The fibrotic process is a crucial component of SSc and is responsible for organ failure and high mortality. Although an increasing understanding of the fibrotic process has enabled the clinical development of antifibrotic therapeutic agents, these agents have limited clinical efficacy. Recently, the potential role of a group of transcription factors containing a High Mobility Group (HMG) motif, in the development and pathological manifestations …

The Effect Of Hunger On The Likelihood Of Glucose Excursions In Adults With Overweight Or Obesity: Continuous Glucose Monitoring And Ecological Momentary Assessment Observational Study, Byunggul Lim, Phrashiah Githinji, Yue Liao, Jacob Szeszulski, Alexandra L Macmillan Uribe, Rebecca A Seguin-Fowler, Jane Anderson, Chad D Rethorst

Faculty, Staff and Students Publications

Background: Maintaining stable glucose levels is important for metabolic health. Glucose excursions (GEs), which are marked increases in glucose following food intake, have been associated with a higher risk for cardiovascular disease and metabolic dysfunction. Individuals with overweight or obesity who do not have diabetes may still show impaired glucose regulation, as reflected in increased glucose variability. Hunger, as a real-time physiological cue, may be associated with subsequent glucose changes and represents a potential target for just-in-time adaptive interventions.

Objective: This study aimed to investigate the temporal relationship between self-reported hunger and subsequent glucose dynamics, including the likelihood of GE …

In Vivo Orf Overexpression Screening Identifies Ccn4 As A Regulator Of Glioblastoma Growth Validated Across Multiple Models, Pushan Dasgupta

Faculty, Staff and Students Publications

Despite current multimodal therapies for glioblastoma (GBM), its prognosis remains grim. Thus, a tremendous need exists to identify new genetic drivers that may serve as potential therapeutic targets in glioblastoma (GBM). We describe an in vivo overexpression screening strategy to identify drivers of glioblastoma where we have leveraged TCGA datasets to conduct a functional genomics screen of prioritized open reading frames (ORFs) that are overexpressed and/or amplified in GBM. To interrogate these potential drivers within a more relevant physiological context, the screening was accomplished in vivo in an orthotopic patient-derived glioma stem-like cell (GSC) model. Among 5 positive "hits" from …

Faculty, Staff and Student Publications

Introduction: Chronic musculoskeletal pain (CMP) is a leading cause of incurred personal healthcare costs and disability in the USA. It disproportionately affects rural populations, who are more likely to be uninsured, lack access to a regular healthcare provider and experience a higher prevalence of CMP. As a result of reduced access to non-pharmacological care, there is greater reliance on opioids. The Auricular Point Acupressure - Self-Management (APA-SM) program is a simple, needleless, evidence-based therapy that empowers individuals to self-manage their pain. Preliminary studies, including a recent UG3 pilot testing, demonstrated feasibility, safety and significant improvements in pain and function. Guided …

Faculty, Staff and Students Publications

Inactivating NOTCH1 mutations in head and neck squamous cell carcinoma (HNSCC) were described over a decade ago, suggesting a tumor suppressor function - unlike its oncogenic role in other tumors. Today, much debate persists regarding a putative oncogenic role in HNSCC as well, with reports that NOTCH1 signaling drives tumor growth and a cancer stem cell (CSC) phenotype. In this work, comprehensive experiments unequivocally demonstrate that NOTCH1 is a tumor suppressor in HNSCC regardless of mutation or activation status and that it reduces CSC frequency. We developed a signature of NOTCH1 activation showing the pathway is associated with very early …
