American Cochlear Implant Alliance Position Statement On Newborn Congenital Cytomegalovirus Screening, Megan Honor Pesch, Kevin David Brown, Amy L Birath, Gail J Demmler-Harrison, Cailtin Sapp, Anne Morgan Selleck, Alex D Sweeney

Faculty, Staff and Students Publications

It is estimated that 1 in every 200 US newborns has congenital cytomegalovirus (cCMV). Delayed identification of cCMV in newborns precludes timely intervention to mitigate sequelae of the infection such as hearing loss and other neurological complications. Newborn testing for cCMV enables appropriate diagnosis and intervention by multidisciplinary teams to properly manage the immediate sequelae of cCMV, avoid unnecessary additional testing that can result from delayed diagnosis, and monitor for future complications. It is the position of the American Cochlear Implant Alliance, the National CMV Foundation, and the American Academy of Otolaryngology-Head and Neck Surgery that universal newborn cCMV screening …

Targeted Inhibition Of Aurora Kinase A Promotes Immune Checkpoint Inhibition Efficacy In Human Papillomavirus-Driven Cancers, Soma Ghosh, Madison P O'Hara, Pragya Sinha, Tuhina Mazumdar, Lacin Yapindi, Jagannadha K Sastry, Faye M Johnson

Faculty, Staff and Student Publications

Background: Human papillomavirus (HPV)-driven cancers include head and neck squamous cell carcinoma and cervical cancer and represent approximately 5% of all cancer cases worldwide. Standard-of-care chemotherapy, radiotherapy, and immune checkpoint inhibitors (ICIs) are associated with adverse effects and limited responses in patients with HPV-driven cancers. The integration of targeted therapies with ICIs may improve outcomes. In a previous study, we demonstrated that Aurora kinase A (AURKA, Aurora A) inhibitors lead to apoptosis of human HPV-positive cancer cells in vitro and in vivo. Here, we explored the potential of Aurora A inhibition to enhance response to ICIs in immune-competent …

Recurrent And Metastatic Head And Neck Cancer: Mechanisms Of Treatment Failure, Treatment Paradigms, And New Horizons, William T. Barham, Marshall Patrick Stagg, Rula Mualla, Michael Dileo, Sagar Kansara

School of Medicine Faculty Publications

Background: Head and neck cancer is a deadly disease with over 500,000 cases annually worldwide. Metastatic head and neck cancer accounts for a large proportion of the mortality associated with this disease. Many advances have been made in our understanding of the mechanisms of metastasis. The application of immunotherapy to locally recurrent or metastatic head and neck cancer has not only improved oncologic outcomes but has also provided valuable insights into the mechanisms of immune evasion and ultimately treatment failure. Objectives: This review paper will review our current understanding of biological mechanisms of treatment failure and metastasis. Published and ongoing …

Gain-Of-Function Tp53 Mutations Induce Non-Canonical Nf-Κb Transcriptional Targets To Promote Tumor Development, Kelsey A. Yutan

Scripps Senior Theses

Background: Gain-of-function TP53 mutations have previously been shown to induce chromosomal instability (CIN) in cancer cells, triggering the cGAS-STING innate immune response and subsequently activating the non-canonical NF-κB (NC-NF-κB) signaling pathway. This signaling cascade promotes cancer cell metastasis and an immunosuppressive tumor microenvironment (TME), significantly impacting tumor development and progression. However, the precise downstream mechanisms by which the mutp53-CIN-cGAS-STING-NC-NF-κB signaling pathway facilitates tumor development and progression remain poorly understood. Here, our objective was to identify direct downstream targets of mutp53-CIN-cGAS-STING-induced NC-NF-κB signaling that potentially impact the TME to promote the development and progression of oral squamous cell carcinoma.

Acute Exacerbations Of Chronic Rhinosinusitis, Robert M. Frederick, Kent Lam, Joseph K. Han

Department of Otolaryngology (ENT) Faculty Publications

Purpose of Review

We aim to highlight recent advancements on the evolving chronic rhinosinusitis (CRS) phenotype: acute exacerbations of chronic rhinosinusitis (AECRS). We focused on studies that expanded the current understanding of its pathophysiology, patient characteristics, and disease burden.

Recent findings

Defining AECRS has been a topic of discussion for many years. A recent regulatory definition of AECRS in the literature incorporates a > 3 day requirement of worsened symptoms and an escalation of treatment. It is important not to rely on patient-reported rescue medication frequency as it was recently demonstrated these are only obtained for 1/3 of reported AECRS episodes. …

Semi-Automated Virtual Endoscopy Of The Frontal Recess, Ali Jafar, William Yao, Martin Citardi

Faculty, Staff and Student Publications

Introduction: Virtual endoscopy (VE) is the computer-based reprocessing of diagnostic imaging to simulate endoscopy of an anatomic region of interest. VE of the Frontal Sinus Outflow Tract (FSOT) may assist surgical planning and education.

Method: VE was performed on 16 normal sinus computed tomography (CT) scans for a total of 32 sides using the "path-to-target" tool on the TruDi surgical navigation system (ver. 2.3; Acclarent, Irving, CA, USA). To aid orientation during VE, planning points were placed on the middle turbinate, ethmoidal bulla, and skull base. The VE representation of anatomy and FSOT accuracy was manually confirmed by reviewing the …

Semi-Quantitative Assessment Of Surgical Navigation Accuracy During Endoscopic Sinus Surgery In A Real-World Environment, David Z Allen, Jason Talmadge, Martin J Citardi

Faculty, Staff and Student Publications

Introduction: Although surgical navigation is commonly used in rhinologic surgery, data on real world performance are sparse because of difficulties in collecting measurements for target registration error (TRE). Despite publications showing submillimeter TRE, surgeons do report TRE of >3 mm. We describe a novel method for assessing TRE during surgery and report findings with this technique.

Methods: The TruDi navigation system (Acclarent, Irving, CA) was registered using a contour-based protocol. The surgeon estimated target registration error (e-TRE) at up to 8 points (anatomic regions of interest [ROI]) during endoscopic sinus surgery (ESS). System logs were used to simulate the localization …

Faculty, Staff and Student Publications

Background and purpose: Prior work on adaptive organ-at-risk (OAR)-sparing radiation therapy has typically reported outcomes based on fixed-number or fixed-interval re-planning, which represent one-size-fits-all approaches and do not account for the variable progression of individual patients' toxicities. The purpose of this study was to determine the personalized optimal timing of re-planning in adaptive OAR-sparing radiation therapy, considering limited re-planning resources, for patients with head and neck cancer (HNC).

Materials and methods: A novel Markov decision process (MDP) model was developed to determine optimal timing of re-planning based on the patient's expected toxicity, characterized by normal tissue complication probability (NTCP), for …

Faculty, Staff and Students Publications

Malignant proliferating trichilemmal tumors (MPTTs), arising from the external root sheath of hair follicles, are exceptionally rare, with limited documentation of their genetic alterations. We present a case of a 64-year-old African American woman who initially presented with a gradually enlarging nodule on her posterior scalp. An initial biopsy at an outside hospital suggested metastatic adenocarcinoma or squamous cell carcinoma (SCC) of an uncertain origin. A subsequent wide local excision revealed a 2.0 cm tumor demonstrating characteristic trichilemmal keratinization, characterized by an abrupt transition from the nucleated epithelium to a laminated keratinized layer, confirming MPTT. Immunohistochemistry demonstrated diffuse p53 expression, …

Extreme Wrinkling Of The Nuclear Lamina Is A Morphological Marker Of Cancer, Ting-Ching Wang, Christina R Dollahon, Sneha Mishra, Hailee Patel, Samere Abolghasemzade, Ishita Singh, Vilmos Thomazy, Daniel G Rosen, Vlad C Sandulache, Saptarshi Chakraborty, Tanmay P Lele

Faculty, Staff and Students Publications

Nuclear atypia is a hallmark of cancer. A recent model posits that excess surface area, visible as folds/wrinkles in the lamina of a rounded nucleus, allows the nucleus to take on diverse shapes with little mechanical resistance. Whether this model is applicable to normal and cancer nuclei in human tissues is unclear. We image nuclear lamins in patient tissues and find: (a) nuclear laminar wrinkles are present in control and cancer tissue but are obscured in hematoxylin and eosin (H&E) images, (b) nuclei rarely have a smooth lamina, and (c) wrinkled nuclei assume diverse shapes. Deep learning reveals the presence …

Targeted Variant Assessments Of Human Endogenous Retroviral Regions In Whole Genome Sequencing Data Reveal Retroviral Variants Associated With Papillary Thyroid Cancer, Erik Stricker, Erin C Peckham-Gregory, Stephen Y Lai, Vlad C Sandulache, Michael E Scheurer

Faculty, Staff and Students Publications

Papillary thyroid cancer (PTC) is one of the fastest-growing cancers worldwide, lacking established causal factors or validated early diagnostics. Human endogenous retroviruses (HERVs), comprising 8% of human genomes, have potential as PTC biomarkers due to their comparably high baseline expression in healthy thyroid tissues, indicating homeostatic roles. However, HERV regions are often overlooked in genome-wide association studies because of their highly repetitive nature, low sequence coverage, and decreased sequencing quality. Using targeted whole-genome sequence analysis in conjunction with high sequencing depth to overcome methodological limitations, we identified associations of specific HERV variants with PTC. Analyzing WGS data from 138 patients …

Challenges In Diagnosing Nasopharyngeal Tumors, Alexandru Aristide Alexe, Mihai Victor Lupascu, Haldun Septar, Anca Pantea Stoian, Andra Iulia Suceveanu, Viorel Gherghina, Iuliana Cindea, Alina Doina Nicoara, Laura Mazilu, Razvan Hainarosie, Felix Voinea, Adrian Paul Suceveanu

Journal of Mind and Medical Sciences

Malignant nasopharyngeal tumors account for approximately 4% of ENT malignant tumor pathology and 1% of all cancers. The diagnosis of nasopharyngeal tumors is often late, the reason being the location in a silent anatomical region in terms of symptomatology and accessibility. Thus, approximately 70% of newly diagnosed patients with nasopharyngeal carcinoma unfortunately present with the condition in an advanced local stage. The early signs and symptoms are varied (nasal obstruction, hearing loss, otalgia, headache) and are usually ignored by the patient and even by the doctor in the initial stage of nasopharyngeal tumor evolution. Approximately 5% of patients have systemic …

Adaptation Of The Protein Misfolding Cyclic Amplification (Pmca) Technique For The Screening Of Anti-Prion Compounds, Katherine Do, Rebeca Benavente, Celso S G Catumbela, Uffaf Khan, Carlos Kramm, Claudio Soto, Rodrigo Morales

Faculty, Staff and Student Publications

Prion diseases result from the misfolding of the physiological prion protein (PrPC) to a pathogenic conformation (PrPSc). Compelling evidence indicates that prevention and/or reduction of PrPSc replication are promising therapeutic strategies against prion diseases. However, the existence of different PrPSc conformations (or strains) associated with disease represents a major problem when identifying anti-prion compounds. Efforts to identify strain-specific anti-prion molecules are limited by the lack of biologically relevant high-throughput screening platforms to interrogate compound libraries. Here, we describe adaptations to the protein misfolding cyclic amplification (PMCA) technology (able to faithfully replicate PrPSc strains) that increase its throughput to facilitate the …

School of Medicine Faculty Publications

The tumor microenvironment (TME) plays a pivotal role in the onset, progression, and treatment response of cancer. Among the various components of the TME, cancer-associated fibroblasts (CAFs) are key regulators of both immune and non-immune cellular functions. Leveraging single-cell RNA sequencing (scRNA) data, we have uncovered previously hidden and promising roles within this specific CAF subgroup, paving the way for its clinical application. However, several critical questions persist, primarily stemming from the heterogeneous nature of CAFs and the use of different fibroblast markers in various sample analyses, causing confusion and hindrance in their clinical implementation. In this groundbreaking study, we …

Adenoid cystic carcinoma (ACC) is a rare, usually slow-growing yet aggressive head and neck malignancy. Despite its clinical significance, our understanding of the cellular evolution and microenvironment in ACC remains limited. We investigated the intratumoral microbiomes of 50 ACC tumor tissues and 33 adjacent normal tissues using 16S rRNA gene sequencing. This allowed us to characterize the bacterial communities within the ACC and explore potential associations between the bacterial community structure, patient clinical characteristics, and tumor molecular features obtained through RNA sequencing. The bacterial composition in the ACC was significantly different from that in adjacent normal salivary tissue, and the …
