The novel (nua) kinases 1 and 2 are two of 12 AMP-activated protein–related kinases whose signaling pathways are involved in cancer progression, as well as neurologic, fibrotic, and inflammatory diseases. Currently, there are 80 Food and Drug Administration-approved kinase inhibitors which target roughly 24 of the 500+ known human kinases, leaving most kinases underexplored, including NUAK1 and NUAK2. Thus, there is a critical need for selective inhibition of NUAK1 and NUAK2 signaling. Here, we review the protein structure, known upstream regulators and downstream targets, and expression profiles of NUAK1 and NUAK2 in cancerous compared to noncancerous tissue. We also delineate …

Context: As the rate of research production accelerates, the ability to efficiently and unambiguously communicate judgments relating to the synthesis, evaluation, and use of scientific information becomes paramount.

Perspective: Scientific information can be viewed as a "layered infrastructure" of data, evidence, knowledge, and use. The GRADE approach serves as a de facto data standard for this infrastructure, supporting movement between layers by reducing ambiguity in claims to knowledge (in the form of judgements of certainty in the evidence when answering research questions) and level of commitment to possible solutions to problems (in the form of strength of recommendations for interventions). …

Radiotherapy is the main treatment modality of oropharyngeal cancer (OPC), in which an accurate segmentation of primary gross tumor volume (GTVt) is essential but also challenging due to significant interobserver variability and the time consumed in manual tumor delineation. For such a challenge an interactive deep learning (DL) based approach offers the advantage of automatic high-performance segmentation with the flexibility for user correction when necessary. In this study, we investigate an interactive DL for GTVt segmentation in OPC by introducing a novel two-stage Interactive Click Refinement (2S-ICR) framework and implementing state-of-the-art algorithms. Using the 2021 HEad and neCK TumOR dataset …

Information Theory Optimization Of Signals From Small-Angle Scattering Measurements, Robert P Rambo, John A Tainer

Faculty, Staff and Student Publications

Small-angle X-ray scattering (SAXS) of particles in solution informs on the conformational states and assemblies of biological macromolecules (bioSAXS) outside of cryo- and solid-state conditions. In bioSAXS, the SAXS measurement under dilute conditions is resolution limited, and through an inverse Fourier transform, the measured SAXS intensities directly relate to the physical space occupied by the particles via the P(r)-distribution. Yet, this inverse transform of SAXS data has been historically cast as an ill-posed, ill-conditioned problem requiring an indirect approach. Here, we show that through the applications of matrix and information theories, the inverse transform of SAXS intensity data is a …

Faculty, Staff and Students Publications

Background: Sturge-Weber syndrome (SWS) is a congenital neurocutaneous disorder characterized by angiomas of the face, choroid, and leptomeninges. Seizures in these children often present within the first 2 years of life. SWS is typically unilateral, but bilateral SWS occurs in approximately 15% of cases. Bilateral SWS is associated with earlier seizure onset and poorer cognitive, developmental, and functional outcomes. More than half of children with SWS develop drug-resistant epilepsy requiring surgical intervention. Hemispherotomy has been established as a successful treatment for unilateral SWS, but resective surgery has traditionally not been considered a treatment option for patients with bilateral disease.

Department of Medicine Faculty Papers

Pandemic lockdown orders resulted in closures to critical community networks. One such infrastructure was community recreation centers/parks. This infrastructure serves a critical role in building psychosocial wellness for youth. Socioeconomic minority youth face baseline disparity in center/park distribution and services. Youth recreation activity declined 50% as result of lockdown orders with corresponding decline in youth mental health status. Despite overall youth activity decline, White and high socioeconomic demographic categories were associated with greatest recreation access during the pandemic. Thus, the pandemic exacerbated preexisting disparities in recreation access for minority youth and its benefit towards adaptive development. Minority youth experienced greater …

Zacaria, Taís L. Denicol, Michel Frudit, Natália Vasconcellos De Oliveira Souza

Department of Neurology Faculty Papers

BACKGROUND AND OBJECTIVES: Elderly patients with subarachnoid hemorrhage (SAH) face a disproportionately high burden of morbidity and mortality. While endovascular coiling is often favored in this population, direct comparisons with surgical clipping are limited. We conducted a meta-analysis to compare outcomes of clipping versus coiling in SAH patients aged ≥ 60 years.

METHODS: A systematic search of PubMed, Embase, and Cochrane databases identified studies comparing the two treatments in this age group. The primary outcome was a composite of unfavorable outcomes (modified Rankin Scale [mRS] > 2 and mortality). Secondary outcomes included mortality, favorable outcome (mRS 0-2), rebleeding, and hospital length …

The complementarity and clinical utility of combining liquid biopsies and radiomic image analysis has not been demonstrated. Circulating tumor DNA (ctDNA) minimal residual disease after chemoradiotherapy (CRT) for non-small cell lung cancer (NSCLC) is highly prognostic, but on-treatment biomarkers are needed to enable response-adapted therapies. Here, we analyzed 418 patients with NSCLC undergoing CRT to develop and validate a novel dynamic risk model that accurately predicts ultimate progression-free survival during treatment. We optimize tissue-free variant calling from plasma samples to facilitate ctDNA monitoring and demonstrate the importance of accounting for persistent clonal hematopoiesis variants. We show that mid-CRT ctDNA concentration …

Evaluating Parotid Gland Dose Between Electronic Tissue Compensation And Field In Field Treatment Techniques For Parotid Sparing In Whole-Brain Radiotherapy, Joesph E. Bodgonas

Masters Projects

Purpose:

The parotid glands are essential to salivary function and patient quality of life, yet they are not routinely prioritized as organs at risk (OARs) during whole-brain radiotherapy (WBRT). With growing recognition of long-term side effects like xerostomia in patients with prolonged survival after WBRT, parotid-sparing techniques warrant investigation. This study compares radiation dose to the parotid glands using three different 3D conformal WBRT planning approaches: field-in-field (FiF) with blocking, electronic tissue compensation (eCOMP) without blocking, and eCOMP with blocking.

Methods and Materials:

A retrospective study was conducted on 20 patients previously treated with 3D conformal WBRT. Original eCOMP plans …

A Comparative Study Of Vmat Beam Arrangements In Large Field Nodal Prostate Treatment Plans, Laura R. Black

Masters Projects

Treatment of extensive prostate and pelvic lymph node volumes for prostate cancer patients provide unique challenges related to limitations in multileaf collimator (MLC) design in many modern linear accelerators. A strategy to overcome this challenge is by restricting the field size, improving modulation as well as using overlapping arcs to ensure complete coverage of the target. Using too few arcs can result in suboptimal target coverage, while too many arcs can lead to prolonged time on the table, increasing the risk of patient movement and potential side effects that may compromise treatment accuracy. This study aims to evaluate the optimal …

Car-Macrophage Cell Therapy: A New Era Of Hope For Pancreatic Cancer, Daoyan Wei, Liang Wang, Yi Liu, Xiangsheng Zuo, Xiling Shen, Robert S Bresalier

Faculty, Staff and Student Publications

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest malignancies, characterized by late diagnosis, early metastasis, and resistance to conventional therapies. A major barrier to effective treatment is its desmoplastic and immunosuppressive tumor microenvironment (TME), which restricts T cell infiltration and dampens responses to immune checkpoint inhibitors (ICIs). These features highlight the urgent need for innovative immunotherapeutic strategies capable of overcoming PDAC's immunologic and physical barriers. Chimeric antigen receptor (CAR)-macrophage (CAR-M) therapy has emerged as a promising approach to address these challenges. Unlike CAR-T or CAR-NK cells, CAR-Ms can efficiently infiltrate tumors, remodel the TME, phagocytose tumor cells, and stimulate …

In a phase II trial, patients with local-regionally advanced human papillomavirus-positive oropharyngeal carcinoma (n = 35) received ipilimumab (anti-CTLA4) and nivolumab (anti-PD-1) as induction immunotherapy and concurrently with radiotherapy (NCT03799445). Coprimary endpoints included 6-month complete metabolic response rate (94%) and 2-year progression-free survival (84%). Induction yielded a 46% major histopathologic response rate. Single-cell profiling revealed responders had higher baseline intratumoral CD8+ T cells with a tumor-reactive, tissue-resident memory (TRM) phenotype and a treatment-related decrease in effector regulatory T (eTreg) cells. The eTreg decrease correlated with CD8+ T-cell clonotype transitioning from TRM to effector memory and IFNG+ effector cells. …

Faculty, Staff and Student Publications

Partial cystectomy is a surgical bladder-sparing option for selected patients with muscle-invasive bladder cancer (MIBC), urachal adenocarcinoma and diverticular bladder tumors. Partial cystectomy hold several advantages. It allows for definite pathology and accurate staging while avoiding side effects from radiation therapy and preserves the option for salvage radical therapy (radical cystectomy or radical radiotherapy). Patients should have a CT urogram, prostatic urethral biopsy and mapping biopsies or blue light cystoscopy to rule out multifocal disease or CIS. Small solitary MIBC patients without carcinoma in situ in an area of the bladder where resection can be performed with negative margin would …

Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal disease characterized by excessive extracellular matrix deposition. Current IPF therapies slow disease progression but do not stop or reverse it. The (myo)fibroblasts are thought to be the main cellular contributors to excessive extracellular matrix production in IPF. Here we show that fibrotic alveolar type II cells regulate production and crosslinking of extracellular matrix via the co-transcriptional activator YAP. YAP leads to increased expression of Lysl oxidase (LOX) and subsequent LOX-mediated crosslinking by fibrotic alveolar type II cells. Pharmacological YAP inhibition via verteporfin reverses fibrotic alveolar type II cell reprogramming and LOX …
