Background: High-grade gliomas are highly invasive and respond variably to chemoradiation. Accurate, patient-specific predictions of tumor response could enhance treatment planning. We present a novel computational platform that assimilates MRI data to continually predict spatiotemporal tumor changes during chemoradiotherapy.

Methods: Tumor growth and response to chemoradiation was described using a two-species reaction-diffusion model of enhancing and non-enhancing regions of the tumor. Two evaluation scenarios were used to test the predictive accuracy of this model. In scenario 1, the model was calibrated on a patient-specific basis (n = 21) to weekly MRI data during the course of chemoradiotherapy. A data assimilation …

Maximizing Relief: The Benefits Of Combining Lateral Femoral Cutaneous Nerve Block With Sciatic Nerve Block In The Emergency Department, Courtney Smith, Taryn Hoffman

Florida Journal of Emergency Medicine (FJEM)

Low back pain accounts for more than 2.6 million emergency department (ED) visits annually, with 40% of Americans experiencing sciatica at some point in their lives. Our case report describes a patient presenting with atraumatic right-sided low back pain and paresthesias in her right leg. We utilized a combination of a transgluteal sciatic nerve block and a lateral femoral cutaneous nerve block to achieve improved pain relief after an initial isolated transgluteal sciatic nerve block left her with persistent anterolateral thigh pain.

We detail the technique for performing this procedure under ultrasound guidance. Our patient experienced significant pain improvement and …

Superficial Cervical Plexus Block For Postoperative Pain Management In Occipital Craniotomies: A Narrative Review, Shahab Ahmadzadeh, Bennett M. Ford, Alex V. Hollander, Mary Kathleen Luetkemeier, Tomasina Q. Parker-Actlis, Sahar Shekoohi

School of Medicine Faculty Publications

Post-craniotomy pain is common yet often sub-optimally managed because systemic opioids can obscure postoperative neurologic examinations. The superficial cervical plexus block (SCPB) has, therefore, emerged as a targeted regional anesthesia option for occipital craniotomies. The SCPB targets the C2-C4 nerves to anesthetize the occipital scalp region, covering the lesser occipital nerve territory that lies within typical posterior scalp incisions. Clinical evidence shows the block is effective in reducing acute postoperative pain after occipital craniotomy and diminishes opioid requirements. Studies have demonstrated successful and long-lasting analgesia, reductions in 24-h opioid consumption, and a lower incidence of severe pain. Moreover, the technique …

Phosphoglycerate Mutase Regulates Treg Differentiation Through Control Of Serine Synthesis And One-Carbon Metabolism, Wesley H Godfrey, Judy J Lee, Shruthi Shanmukha, Kaho Cho, Xiaojing Deng, Chandra Shekar R Ambati, Vasanta Putluri, Abu Hena Mostafa Kamal, Paul M Kim, Nagireddy Putluri, Michael D Kornberg

Faculty, Staff and Students Publications

The differentiation and suppressive functions of regulatory CD4 T cells (Tregs) are supported by a broad array of metabolic changes, providing potential therapeutic targets for immune modulation. In this study, we focused on the regulatory role of glycolytic enzymes in Tregs and identified phosphoglycerate mutase (PGAM) as being differentially overexpressed in Tregs and associated with a highly suppressive phenotype. Pharmacologic or genetic inhibition of PGAM reduced Treg differentiation and suppressive function while reciprocally inducing markers of a pro-inflammatory, T helper 17 (Th17)-like state. The regulatory role of PGAM was dependent on the contribution of 3-phosphoglycerate (3 PG), the PGAM substrate, …

A Novel Microdosimetry-Based Formalism For Cell Survival Modelling Applicable To Hypofractionated Radiotherapy, Oleg N Vassiliev, Radhe Mohan

Faculty, Staff and Student Publications

Objectives

Hypofractionated radiotherapy requires reliable cell survival models for doses much higher than the standard 2 Gy, for which the linear-quadratic (LQ) model is not applicable. We developed an alternative approach applicable to both low doses and high doses used in hypofractionated treatments and radiobiological experiments.

Approach.

We combined a standard microdosimetric technique with a recently introduced non-LQ cell survival model. Our formulation accounts for cell damage by multi-track events involving any number of particles. This is necessary for modelling cell survival at therapeutic doses. We characterise each cell type by the size �� of the sensitive volume (SV) and …

Use Of Cholic Acid In Smith-Lemli-Opitz Syndrome (Slos): Real-World Patient Outcomes, Edwin Ferren, Paul R Hillman, Amy Kritzer, Joseph Ray, Alvaro Serrano, Hope Northrup, Paige Roberts, Rana Dutta, Tiziano Pramparo, Pamela Vig, Robert D Steiner

Faculty, Staff and Student Publications

Background: Smith-Lemli-Opitz Syndrome (SLOS) is an autosomal recessive disorder of cholesterol biosynthesis caused by biallelic pathogenic variants in DHCR7, which encodes the enzyme 7-dehydrocholesterol reductase (DHCR7). SLOS is a multisystemic disorder affecting various aspects of health, including growth, development, behavior, and quality of life, underscoring the need for safe, efficacious interventions that limit disease burden. DHCR7 enzyme deficiency leads to a "metabolic block" resulting in decreased cholesterol production and accumulation of its precursor 7-dehydrocholesterol and the secondary isomer 8-dehydrocholesterol. Reduced cholesterol synthesis, in turn, leads to decreased levels of cholic acid (CA), an endogenous bile acid synthesized from cholesterol and …

Medulloblastoma (MB) is the most malignant childhood brain cancer. Group 3 MB (G3 MB) subtype accounts for about 25% of MB and is associated with the worst outcomes. Herein, we report that more than half of G3 MB tumors express melanoma antigens (MAGEs), which are potential prognostic and therapeutic markers. MAGEs are cancer-testis antigens, aberrantly expressed in several adult cancers, and associated with poorer prognosis and therapy resistance; however, their role in pediatric cancers is mostly unknown. This study aimed to determine whether MAGEs are activated and important in pediatric MB. We obtained formalin-fixed paraffin-embedded tumor samples of 34 patients, …

Dietary Lipids Induce Ppard And Bcl6 To Repress Macrophage Il-23 Induction After Intestinal Injury And Lps Exposure, Ashleigh M Gil, Daniel F Zegarra-Ruiz, Wan-Jung Wu, Kendra Norwood, Adrien Assie, Buck S Samuel, Angela M Major, Gretchen E Diehl, Andrea A Hill Mcalester

Faculty, Staff and Students Publications

Unresolved tissue damage is a common feature of Inflammatory Bowel Disease (IBD) that facilitates disease progression. Here, we showed that high animal fat diets (HFD), an environmental risk factor associated with IBD pathogenesis, suppress intestinal macrophage production of critical tissue repair responses after damage. This includes reduced IL-23 production, which drives downstream production of IL-22, which is needed for barrier repair. Indicating that dietary lipids interfere with responses to microbial molecules needed to induce barrier protective functions, we found oleic acid could directly suppress macrophage Il23a induction after lipopolysaccharide (LPS) treatment. Deleting the lipid transporter CD36 on macrophages restored the …

Division of Cardiology Faculty Papers

Introduction: Leadless intracardiac pacemakers (LICPs) reduce lead-related complications but may be malpositioned in patients with unrecognized structural defects. We report a 69-year-old man with high-grade AV block whose LICP, intended for right ventricular placement, was found in the left ventricle via an undiagnosed ostium secundum ASD after presenting with multifocal embolic strokes 16 months later. Case Presentation: Stroke workup for acute right-sided symptoms revealed the LICP in the LV and a large, previously undiagnosed ASD with bidirectional shunting and severe pulmonary hypertension. Embolic infarcts were attributed to either paradoxical embolism or device-related thromboembolism. Due to high surgical risk, …

Combination Of Irreversible Electroporation And Clostridium Novyi-Nt Bacterial Therapy For Colorectal Liver Metastasis, Zigeng Zhang, Guangbo Yu, Qiaoming Hou, Farideh Amirrad, Sha Webster, Surya M. Nauli, Jianhua Yu, Vahid Yaghmai, Aydin Eresen, Zhuoli Zhang

Pharmacy Faculty Articles and Research

Colorectal liver metastasis (CRLM) poses a significant challenge in oncology due to its high incidence and poor prognosis in unresectable cases. Current treatments, including surgical resection, systemic chemotherapy, and liver-directed therapies, often fail to effectively target hypoxic tumor regions, which are inherently more resistant to these interventions. This review examines the potential of a novel therapeutic strategy combining irreversible electroporation (IRE) ablation and Clostridium novyi-nontoxic (C. novyi-NT) bacterial therapy. IRE is a non-thermal tumor ablation technique that uses high-voltage electric pulses to create permanent nanopores in cell membranes, leading to cell death while preserving surrounding structures, and …

Comparison Of Recurrence Rates In Chemical Matricectomy With Phenol And Nail Bracing: A Scoping Review, Jessica Sima, Amanda Killeen

School of Podiatric Medicine - Student Research

Introduction: Ingrown toenails are one of the most common nail conditions and are usually treated with chemical matricectomy using phenol (CMP). However, this procedure is often contraindicated in patients with diabetes mellitus or peripheral vascular disease. Orthonyxia, or nail braces application, is a non-invasive alternative treatment for ingrown toenails. The nail braces are spring wires with one side shaped into a hook that is placed under one side of the nail, and the other side attached to a plastic pad that is glued to the nail plate. The braces retain the normal shape of the nails without removing them, allowing …

Demystifying The Nuances Of The Lipid Patient: A Guide For Primary Care Providers, Merle Myerson, Kyle Gillett, James O'Hara, Richard Potter, Neil Skolnik

Abington Jefferson Health Papers

Atherosclerosis, a major cause of mortality and morbidity in the United States (US), is driven by complex factors, including the cumulative burden of low-density lipoprotein cholesterol (LDL-C) and other atherogenic lipids and lipoproteins. Lipid management in US primary care aims to prevent atherosclerotic cardiovascular disease (ASCVD) events through screening and LDL-C lowering to risk-based goals. However, lipid screening and ASCVD treatment is often inadequate, with few patients meeting LDL-C goals in clinical practice. Primary care providers have a vital role in identifying patients most at risk of ASCVD to prevent ASCVD events and improve patient outcomes. There are multiple different …

Research outputs 2022 to 2026

Resistance to multi-tyrosine kinase inhibitors (TKI) is a major clinical concern in advanced hepatocellular carcinoma (HCC). Herein, we aimed to uncover the mechanisms underlying pan-TKI resistance and to identify potential therapeutic targets. We used multiple TKI-resistant HCC cell lines to identify caveolin-1 (CAV1) as a key driver of therapeutic resistance. CAV1 downregulation induced apoptosis, inhibited metastasis and restored TKI sensitivity in both inherent and acquired TKI-resistant HCC cells. Mechanistically, in acquired TKI-resistant cells aberrant CAV1/STAT3/P70S6K signalling is required for their survival, motility, and invasiveness. CAV1 inhibition reduced expression of dormancy regulators E-cadherin, RAC1 and p21, enhanced cancer stemness markers, and …

Impact Of Prostate Volume On Dose Fall-Off And Organ-At-Risk Exposure In Vmat For Prostate Cancer, Zhikang Jiang

Masters Projects

Prostate cancer remains one of the most prevalent malignancies among men, with radiotherapy, particularly VMAT—playing a central role in its management. VMAT allows for highly conformal dose delivery, but treatment planning must strike a careful balance between achieving steep dose gradients around the prostate and minimizing radiation exposure to nearby organs at risk (OARs), such as the bladder and rectum. This study aimed to evaluate how prostate volume influences dose fall-off characteristics and OAR dose exposure in VMAT treatment plans, providing insights into optimizing radiotherapy for patients with varying prostate sizes. A retrospective analysis was conducted on 50 prostate cancer …

Assessment Of Dnase Activity By Ratiometric Fluorescence Resonance Energy Transfer, Candace L Minchew, Vladimir V Didenko

Faculty, Staff and Students Publications

The present protocol describes a simple and sensitive ratiometric Förster resonance energy transfer (FRET) assay for the detection and quantitative assessment of DNase activity. Ratiometric FRET measurements make use of the ratio of donor and acceptor emission signals. The assay detects single-stranded DNA breaks using a staple-shaped, dual-tagged 38-mer FRET oligoprobe, employed as a real-time DNA cleavage sensor. The main application of the described approach is the quantitative assessment of the effects of reaction conditions, such as pH, temperature, and buffer composition, on DNase activity. Due to its ability to detect even minor and slow DNA cleavage, the assay is …

Breast cancer is the most common malignancy in females and remains the leading cause of cancer-related deaths for women worldwide. The cellular and molecular basis of breast tumorigenesis is not completely understood partly due to the lack of human research models which simulate the development of breast cancer. Here, we developed a method for generating functional mammary-like cells (MCs) from human-induced pluripotent stem cells (iPSCs). The iPSC-MCs closely resemble human primary MCs at cellular, transcriptional, and functional levels. Using this method, a breast cancer model was generated using patient-derived iPSCs harboring germline

BACKGROUND: Spinal cord injury (SCI) clinical trials typically rely on a single primary endpoint to assess drug efficacy. This strategy fails to adequately capture the full impact of treatment in heterogenous neurological conditions like SCI. A more patient-centric analysis requires assessment of neurological function, functional capacity, and quality of life, incorporating meaningful patient-reported outcomes. The global statistical test (GST) addresses this challenge using a unified statistical conclusion regarding the superiority of a treatment strategy over another by evaluating multiple trial endpoints simultaneously.

METHODS: The RISCIS trial (Safety and Efficacy of Riluzole in Acute Spinal Cord Injury Study) data was analysed …
