Serial False Lumen Patency Evaluation Of A Type B Dissection Represented With Malperfusion Following Medical Management, S Taha Zaidi, Quang Le, Firas Mussa, Akiko Tanaka, S Keisin Wang, Arash Keyhani, Kourosh Keyhani

Faculty, Staff and Student Publications

False lumen evolution in type B aortic dissection, particularly with medical management and anticoagulation, remains incompletely understood. We report a 55-year-old man on apixaban for pulmonary embolism with a subacute zone 3-10L TBAD without malperfusion. He was managed medically initially and represented twice over 2 months with back pain and acute right lower extremity ischemia. Serial imaging demonstrated dynamic remodeling with progression from partial to near-complete thrombosis to full reperfusion with true lumen compression. Urgent endovascular repair was performed successfully. This case illustrates the unpredictable course of medically managed TBAD and need for judicious use of anticoagulation.

Capecitabine/temozolomide (CAPTEM) is an established regimen for patients with metastatic pancreatic neuroendocrine tumors (PanNET) that is being increasingly used for tumor volume reduction in patients with borderline anatomically resectable disease. We sought to understand the response of the primary tumor, defined as changes in the tumor–vascular interface (TVI). This is a retrospective, single-institution study of patients with locally advanced or metastatic PanNET treated with CAPTEM between 2010 and 2020. RECISTv1.1 measurements and TVI assessments of the primary tumor were performed on pre- and post-therapy images. Patients with locally advanced or metastatic PanNET at presentation (n = 47) were included. …

Cancer-induced cachexia and anorexia are debilitating complications across many cancers, yet effective treatments remain limited due to a poor understanding of the underlying mechanisms. Here, we identify an uncharacterized tumor-immune-neural circuit driving these syndromes, centered on growth and differentiation factor 15 (GDF15). Using genetically engineered mouse models, we find that loss of GDF15 protects against appetite loss, muscle wasting, and fat loss in pancreatic, lung, and skin cancers. Single-cell RNA sequencing reveals macrophages as a major source of GDF15, induced by tumor-derived colony-stimulating factor 1 (CSF1). GDF15 acts via the central nervous system to enhance β-adrenergic signaling in the tumor …

Faculty, Staff and Student Publications

Use of glucagon-like peptide-1 receptor agonists (GLP1-RA) for weight loss is increasing; implications in breast cancer (BC) survivors remain unclear.This retrospective cohort study evaluated treatment patterns, weight loss, and outcomes in BC survivors at an academic institution receiving GLP1-RA. We evaluated patients with non-metastatic (ductal carcinoma in situ (DCIS), stage 1-3) BC who received GLP1-RA (2005 - 2024). Linear regression models estimated associations between weight change and clinical factors. After excluding DCIS, propensity score matching (1:2) was used to match patients who received GLP1-RA with patients who did not, based on confounding covariates. Kaplan-Meier estimates and log-rank tests compared disease-free …

Albumin-Binding Domains In Therapeutic Protein Engineering: A Structural And Computational Perspective On Rational Design, Matthew Argyle, Dallin M. Chipman, Anna Claire Woolley, Bradley C. Bundy, Dennis Della Corte

Faculty Publications

Therapeutic proteins face a critical pharmacokinetic challenge: rapid clearance from circulation limits their clinical efficacy. Albumin-binding domains (ABDs) offer an elegant solution by enabling therapeutic proteins to “hitchhike” on serum albumin’s favorable 19-day half-life through FcRn-mediated recycling. Clinical validation through approved therapeutics like ozoralizumab demonstrates the success of this approach, with preclinical studies showing fusion to an ABD extended half-life to 18 days. This review provides an analysis of ABD-fusion protein design, integrating structural biology, computational prediction, and rational engineering principles. We catalog the major classes of albumin-binding modalities, including bacterial three-helix bundle domains, engineered peptides, antibody-derived binders, and alternative …

Post-Traumatic Stress And Post-Traumatic Growth: A Literary Lens On Trauma, Meaning, And Survival, Audrey Gruben

CAFE Symposium 2026

This project examines how literature provides insight into these differing trauma responses by comparing Man’s Search for Meaning by Viktor Frankl and Slaughterhouse-Five by Kurt Vonnegut. Drawing on contemporary psychological frameworks of PTSD and PTG, this analysis argues that psychological distress and growth are not mutually exclusive responses to trauma. Instead, they can coexist along a spectrum shaped by meaning-making, responsibility, avoidance, and engagement with suffering.

Comparing Sociological Suicide Studies In The 1800s To Psychological Suicide Studies Now, Amanda Mic

CAFE Symposium 2026

Sociology can look at the numbers and explain to us the physical, concrete facts about when, where, and how suicides happen, but psychology gives us an explanation as to why it happens. This project looks into the ways that 19th century societal stigmas around suicide caused inaccuracies in the statistics that sociologists studied, and therefore their findings, as well as the abundance of discoveries on suicide and mental conditions by psychologists in more recent times.

Evaluating The Residential Lead Remediation Program In The City Of Lancaster, Kaitlin Mcgowan, Divine Oludi, Harriet Okatch

Phase 1

Introduction: Residential lead remediation is an effective primary prevention approach for addressing lead exposure. Current guidelines require residents of a home get relocated during the remediation. Relocation is often for a period of ten days; however, no study has explored the effect of relocation on families. This study aims to understand the experiences of relocated families with a goal to develop a framework for relocation informed by the experiences of previously relocated families.

Methods. Ten semi-structured interviews were conducted with individuals from the city of Lancaster whose homes had been remediated during the last two years. Participants described their …

Bioactive Lipid-Mediated Structural And Functional Regulation Of The Essential Human Potassium Channel Kir7.1, Qingwei Niu, Simon Vu, Yuanjian Xu, Mingxing Qian, Anastasiia Rudenko, Jin Ye, Jianwei Zeng, Wei Huang, Douglas F Covey, Rui Zhang, Ziao Fu, Polina V Lishko

2020-Current year OA Pubs

The inwardly rectifying potassium channel Kir7.1 is essential for the physiological function of diverse tissues, including the retinal pigment epithelium and the gestational myometrium. Loss-of-function mutations in KCNJ13, which encodes Kir7.1, or conditional ablation of Kir7.1 in the retinal pigment epithelium, lead to early-onset vision loss. Despite strong genetic evidence supporting Kir7.1 as a therapeutic target, its regulation by endogenous ligands-beyond phosphoinositides-remains poorly understood. Here, we report cryo-electron microscopy structures of human Kir7.1 in multiple functional states at resolutions ranging from 2.8 Å to 4.0 Å. These structures uncover the molecular basis of Kir7.1 modulation by PI

Interrelationship Between Body Mass Index, Venous Sinus Pressures, Craniospinal Elastance, And Intracranial Pressure In Idiopathic Intracranial Hypertension, Rachel Wang, Scott W. Keith Phd, Pascal Jabbour Md, Stavropoula Tjoumakaris Md, Michael J. Marmura Md, M. R. Gooch Md, Hsiangkuo Yuan Phd

Phase 1

Introduction/Purpose: Body mass index (BMI), venous sinus pressure (VSP), and craniospinal elastance each correlate with lumbar puncture opening pressure (LP OP) in idiopathic intracranial hypertension (IIH), but their mechanistic interactions remain unclear. This study examined how these factors jointly influence OP, hypothesizing that BMI has a stronger positive association with intracranial pressure (ICP) when elastance is elevated.

Methods: A single-center retrospective review was conducted to identify patients who underwent venous manometry (8/2021–11/2025) followed by LP within 7 days. VSPs were recorded at the torcula (TP) and sigmoid/jugular (SIJ) sinuses. Elastance was calculated as (OP – closing pressure)/volume of CSF removed. …

Cardiovascular Outcomes In Smoking And Nonsmoking Psoriasis Patients On Low- And Moderate-Intensity Statin Therapy, Eliana Khojasteh, Mahaa Ayub, Julianne Bartz, Matthew Keller, Md

Phase 1

Introduction: Psoriasis is associated with increased cardiovascular risk, and smoking amplifies this burden by worsening cardiovascular outcomes and psoriasis severity. Statins are the cornerstone of cardiovascular risk reduction; however, their lipid-lowering effectiveness in psoriasis patients across smoking statuses remains incompletely understood. This study evaluated whether smoking status influences LDL-C before and after statin initiation in adults with psoriasis.

Methods: We conducted a retrospective chart review of adults with psoriasis treated at Thomas Jefferson University Hospital between 2014 and 2024 who were prescribed low- or moderate-intensity statins. Data collected included smoking status (current vs. former/never) and LDL-C values before and at …

Effect Of Adherent Cpap Use On Dyslipidemia, Evelyn Miller, Cindy Cheng, Md, Phd

Phase 1

Introduction/Purpose: Obstructive sleep apnea (OSA) is characterized by upper airway closure during sleep, resulting in surges of sympathetic activity, elevated blood pressure and arterial oxygen desaturation. Over time, this can lead to systemic hypertension, congestive cardiac failure, and acute coronary syndrome. The current gold standard treatment is CPAP (continuous positive pressure airway),  which reduces blood pressure and heart rate while improving oxygen saturation. However, the effect of CPAP treatment on dyslipidemia is less understood.  Accordingly, this study aims to determine the effect of adherent CPAP use on dyslipidemia in our sleep medicine practice in Philadelphia.

Methods: The retrospective …

Utility Of Neurosurgery-Specific Rag-Llm In Accurate Patient Outcome Prediction, Alexander Hone, Basel Musmar, Joanna Roy, Pascal Jabbour

Phase 1

Large Language Models (LLMs) have been previously utilized in the medical field to successfully generate information. However, LLMs may hallucinate, which generates a response based on false or misleading information. This can negatively impact healthcare outcomes, thus, there is an increasing need to develop a model free of hallucinations.

A multi-target voting ensemble (Random Forest with HistGradientBoosting) algorithm was utilized in the analysis of 454 training data and 114 test data. Raw accuracy and macro-F1 statistics determined that the model is capable of identifying clinically meaningful data for majority classes, while minority-class detection was insignificant. This demonstrates moderate predictive value …

Noninvasive Patient-Level Detection Of Nafld Using Mri Radiomics And Machine Learning, Vladimir Kirichenko, Rajanikanth Vadigepalli

Phase 1

Introduction— Current noninvasive assessment of nonalcoholic fatty liver disease (NAFLD) relies primarily on MRI-based fat quantification, such as proton density fat fraction (PDFF). This study explored the use of an MRI radiomics–based machine learning approach for accurate patient-level classification of NAFLD.

Methods— Liver MRI images from patients with suspected NAFLfD were retrospectively analyzed. Radiomics features were extracted using PyRadiomics from full-liver masks across 4–6 axial slices per patient. Slice-level features were aggregated to the patient level using summary statistics (mean, median, and standard deviation). To reduce redundancy and multicollinearity, features were pruned using Pearson correlation analysis with a threshold of …

Sodium-Glucose Cotransporter 2 Inhibitors And Vulvovaginal Candidiasis, Gabriela Skovronsky, Natalie Suozzi, Paul Nyirjesy

Phase 1

Introduction: Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are widely used for type 2 diabetes management, but are associated with increased risk of genital infections. Despite their use, there is limited evidence to quantify this risk. We conducted a systematic review to determine the incidence of vulvovaginal candidiasis (VVC) in patients taking SGLT2is compared to other diabetes treatments. We hypothesized that SGLT2i use would be associated with an increased incidence of VVC compared to other treatments.

Methods: Using PRISMA guidelines, we searched five databases using MESH terms for studies examining VVC in females with type 2 diabetes mellitus treated with SGLT2is versus …

Sodium-Glucose Cotransporter 2 Inhibitors And Vulvovaginal Candidiasis, Natalie Suozzi, Gabriela Skovronsky, Paul Nyirjesy

Phase 1

Introduction: Sodium-glucose transporter 2 inhibitors (SGLT2is) are associated with an increased risk of vulvovaginal candidiasis (VVC), negatively impacting quality of life. Most studies evaluate risk with individual SGLT2is or the class as a whole, rather than comparing risk between different SGLT2is. The objective of this study was to compare the risk of VVC across individual SGLT2is.

Methods: We conducted a systematic review to find studies examining VVC rates in women taking SGLT2is. Of 74 studies identified, four met inclusion criteria for a meta-analysis, with several others used for background. For canagliflozin, ertugliflozin, and empagliflozin, we calculated risk ratios and …
