Department of Medicine Faculty Papers

Degenerative joint disease remains a leading cause of global disability, with early diagnosis posing a significant clinical challenge due to its gradual onset and symptom overlap with other musculoskeletal disorders. This review focuses on emerging diagnostic strategies by synthesizing evidence specifically from studies that integrate biochemical biomarkers, advanced imaging techniques, and machine learning models relevant to osteoarthritis. We evaluate the diagnostic utility of cartilage degradation markers (e.g., CTX-II, COMP), inflammatory cytokines (e.g., IL-1β, TNF-α), and synovial fluid microRNA profiles, and how they correlate with quantitative imaging readouts from T2-mapping MRI, ultrasound elastography, and dual-energy CT. Furthermore, we highlight recent developments …

Tumor Microenvironment Governs The Prognostic Landscape Of Immunotherapy For Head And Neck Squamous Cell Carcinoma: A Computational Model-Guided Analysis, Priyan Bhattacharya, Alban J Linnenbach, Andrew P. South, Ubaldo E. Martinez-Outshoorn, Joseph M. Curry, Jennifer M. Johnson, Larry A. Harshyne, Mỹ G. Mahoney, Adam J. Luginbuhl, Rajanikanth Vadigepalli

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Immune checkpoint inhibition (ICI) has emerged as a critical treatment strategy for squamous cell carcinoma of the head and neck (HNSCC) that halts the immune escape of the tumor cells. Increasing evidence suggests that the onset, progression, and lack of/no response of HNSCC to ICI are emergent properties arising from the interactions within the tumor microenvironment (TME). Deciphering how the diversity of cellular and molecular interactions leads to distinct HNSCC TME subtypes subsequently governing the ICI response remains largely unexplored. We developed a cellular-molecular model of the HNSCC TME that incorporates multiple cell types, cellular states, and transitions, and molecularly …

Comparison Of Open And Laparo-Endoscopic Repair Techniques For Patients With Bilateral Inguinal Hernias, Divyansh Agarwal, Tina Bharani, Nora Fullington, Lauren Ott, Kortney Hodgson, Daelyn Mcclain, Kaela Blake, Michael Reinhorn

Department of Surgery Faculty Papers

INTRODUCTION: For primary bilateral inguinal hernias, international guidelines favor a laparoscopic posterior mesh repair due to relatively lower risk of acute and chronic pain, faster recovery, and favorable biomechanical properties compared to open anterior approaches (Lichtenstein, plug and patch, etc.). However, studies comparing open mesh-based bilateral inguinal hernia repairs to bilateral laparoscopic and robotic mesh-based approaches are limited. The Abdominal Core Health Quality Collaborative (ACHQC) registry includes longitudinal data on bilateral inguinal hernia repairs performed via open as well as laparo-endoscopic approaches. We hypothesize that outcomes for bilateral inguinal hernia repair are similar between open and laparo-endoscopic approaches in the …

Einstein Health Papers

BACKGROUND: Estimated plasma volume status (ePVS) correlates with intravascular congestion and prognosis in patients with heart failure. The ePVS relationship with invasive hemodynamic profiling and clinical outcomes in patients with liver cirrhosis (LC) remains unclear.

METHODS: This single-center retrospective cohort study included LC patients who underwent right heart catheterization (RHC) between 2018 and 2023. Estimated plasma volume status (ePVS) was calculated using the Strauss-derived Duarte formula, with patients classified into high (> 5.5%) and low-ePVS (≤ 5.5%) groups. Cox-multivariable analysis was used to determine if ePVS was associated with all-cause mortality within 1 year post-RHC among transplant-free patients.

RESULTS: Of …

Colorectal cancer (CRC) is one of the most common causes of cancer deaths in the United States in both males and females. However, the influence of suicidal ideation (SI) on the association between CRC and risk of mortality has not been well examined.

METHODS: For this study, the 2005-2018 National Health and Nutrition Examination Survey (NHANES), a nationally representative survey of United States adults aged 20 years or older, was utilized. CRC survivorship was determined from self-reported data on CRC, and mortality …

Neovascular Pruning By Ido1 Inhibitors Can Potentiate Immunogenic Cytotoxicity Of Ischemia-Targeted Agents To Synergistically Enhance Anti-Pd-1 Responsiveness, Shih-Chun Shen, Souvik Dey, James B. Duhadaway, Erika Sutanto-Ward, Maurice T. Hampton, Serguei V. Kozlov, George C. Prendergast, Alexander J. Muller

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Strategies for deploying indoleamine 2,3-dioxygenase 1 (IDO1)-targeted therapies for use against cancer have focused on IDO1's role in promoting peripheral immune tolerance that shields tumors from effector T cells. However, preclinical investigation of both primary and metastatic tumor development in the lungs has uncovered a previously unappreciated role for IDO1 in directing a counterregulatory response to interferon (IFN)-γ that realigns the local inflammatory environment to promote tumor neovascularization. Understanding how to therapeutically leverage the ability of IDO1 inhibitors to subvert inflammatory neovascularization within the tumor microenvironment has potential ramifications for future clinical development of these compounds.

METHODS: Pulmonary metastases …

Decompression With Intradural Dissection For The Chiari Malformation Type I: Toward Eliminating Wound Complications, Anna Lin, Lindsey Asti, Marissa Carroll, Jeffrey Campbell, Jospeh Piatt

Department of Neuroscience Faculty Papers

BACKGROUND: There is continuing conversation about surgical technique in the management of the Chiari malformation. Popular options include osseous decompression alone, decompression with dural splitting, and decompression with intradural dissection (DID) and duraplasty. Wound complications after intradural dissection are a persistent problem. The current study of an institutional series examines wound complication rates after intradural dissection without dural closure.

METHODS: A retrospective single-institution chart review was performed for patients < 21 years with Chari malformation type I who underwent DID without dural closure and had at least 6 months of follow-up. Bone removal corresponded to the area of attachment of the rectus capitis posterior minor muscles together with laminectomy of the atlas. The trapezius and semispinalis capitis muscles were retracted but were not separated from the occiput.

RESULTS: A total of 76 patients were treated from May 2010 through May 2024. Thirty-eight (50.0%) patients had syringomyelia. The median age at surgery was 9 years (interquartile range [IQR] 4-13), …

Identification Of Surrogate Biomarkers For Mucopolysaccharidosis Type Iva, Yasuhiko Ago, Shaukat Khan, Kimberly Klipner, Allison Bradford, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis type IVA (MPS IVA, Morquio A syndrome) is a rare inherited disorder characterized by skeletal dysplasia due to deficient N-acetylgalactosamine-6-sulfate sulfatase activity, resulting in glycosaminoglycan (GAG) accumulation. Identifying accurate biomarkers reflecting clinical severity and therapeutic response remains challenging. This study evaluated potential surrogate biomarkers, including N-terminal pro-C-type natriuretic peptide (NT-proCNP), collagen types I and II, mono-sulfated keratan sulfate (KS), di-sulfated KS, and chondroitin-6-sulfate (C6S), in blood and urine samples from 60 patients ranging from 1 to 62 years of age. NT-proCNP levels were significantly elevated in patients of all ages and negatively correlated with growth impairment, especially after 8 …

Imaging Hallmarks Of Idiopathic Intracranial Hypertension And Insights Into Pathogenesis, Albalooshy Basimah, Scott Faro, Hsiangkuo Yuan, Kiran Talekar, Prabath Mondel, Enchao Qiu, Joga Chaganti

Department of Radiology Faculty Papers

Idiopathic Intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a term used to describe increased intracranial pressure in the absence of a known identifiable secondary cause. Despite advancements of neuroimaging techniques, imaging of the pathological underpinnings in the diagnosis of IIH has been limited. Although the causation of IIH has been ascribed to increased Cerebrospinal Fluid production and disordered drainage through the dural sinuses, new evidence shows that the glymphatic system which is an alternate pathway of drainage is likely to play a pivotal role. In this review, we address the pathophysiological underpinnings in the causation of IIH …

Optimal Diagnostic Strategies For Concussion-Related Vision Disorders: A Review, Iniya K. Adhan, Kammi B. Gunton

Wills Eye Hospital Papers

Concussions are a mild form of traumatic brain injury (TBI) that is typically self-limited and transient with a high prevalence within our communities. Due to the vast visual network interconnectivity, visual symptoms secondary to a concussion occur about 90% of the time. A gold standard to confirm concussion acutely has not been well established. Visual function testing based on symptoms remains the standard of care in off-site evaluation for diagnosis of oculomotor dysfunction. This review covers the current diagnostic strategies for vision based disorders post-concussion for sideline testing, off-site testing, and research driven testing.

Impaired Dnajb2 Response To Heat Shock In Fibroblasts From A Neuropathy Patient With Dnajb2/Hsj1 Mutation: Cystamine As A Potential Therapeutic Intervention, Raj K. Pradhan, Nikolas G. Kinney, Brigid K. Jensen, Hristelina Ilieva

Farber Institute for Neuroscience Faculty Papers

Background and Objectives: Neuropathy is a debilitating disorder characterized by peripheral nerve dysfunction and damage to sensory, motor, and autonomic neurons and their axons. While homozygous mutations in DNAJB2/HSJ1 have been linked to early-onset neuropathy, a heterozygous DNAJB2 c.823+6C>T was discovered in an adult patient with severe sensory–motor polyneuropathy. This mutation is predicted to affect both isoforms of the protein. DNAJB2 (HSP40), a key member of the heat shock protein family, plays a critical role in cellular protection and stress, including response to heat shock. DNAJB2 traffics unfolded proteins to another heat shock protein, HSP70, and activates its ATPase …
