Previously, a synchrotron-based horizontal proton beamline (87.2 MeV) was successfully commissioned to deliver radiation doses in FLASH and conventional dose rate modes to small fields and volumes. In this study, we developed a strategy to increase the effective radiation field size using a custom robotic motion platform to automatically shift the positions of biological samples. The beam was first broadened with a thin tungsten scatterer and shaped by customized brass collimators for irradiating cell/organoid cultures in 96-well plates (a 7-mm-diameter circle) or for irradiating mice (1-cm

Purpose: There currently are no established formal mentorship and training programs for radiation oncology (RO) trainees to learn trial design, creation, writing, or implementation. There only exists informal training on analyzing clinical trials in RO residency programs. The integration of a longitudinal formal training and mentorship program for clinical trialists-consisting of clinical trial education, design, mentorship, and implementation during the RO residency education-will give residents not only formal teaching in the subject but also strong tools and requisite mentorship in hopes to help them succeed as future academic physicians and leaders in the field of RO.

We hypothesized that pre-consult patient education videos can improve patient understanding about their diagnosis, lead to high satisfaction and low distress. In this pilot study, we developed a patient education video curriculum for patients with newly-diagnosed anal cancer. Comprehension of key content was evaluated by comparing pre- and post-test scores. Patient satisfaction scores were collected. Patient distress scores (0-10) were collected at the beginning of their consult visit prior to seeing the physician. We found that patient education videos prior to consult improved patient understanding, resulted in high patient satisfaction, and low patient distress at the time of consult.

Refractory aggressive lymphomas can be treated with allo-SCT, pursuing a graft-vs-lymphoma effect. While reduced intensity conditioning is safe, tumors often progress rapidly, indicating the need for more active conditioning regimens. The preclinical synergy we saw between gemcitabine (Gem), clofarabine (Clo) and busulfan (Bu) against lymphoma cell lines led us to study Gem/Clo/Bu clinically. Eligibility: age 12-65, refractory aggressive B-NHL, T-NHL or Hodgkin, with a matched donor. Infusional Gem was dose-escalated on days (d) -6 and -4 (475-975 mg/m2/day), followed by Clo (40 mg/m2/day) and Bu (target AUC, 4000 μMol min/day) (d -6 to -3). CD20+ tumors received rituximab. GVHD prophylaxis …

Cutaneous T cell lymphoma (CTCL) is a potentially fatal clonal malignancy of T cells primarily affecting the skin. The most common form of CTCL, mycosis fungoides, can be difficult to diagnose, resulting in treatment delay. We performed single-cell and spatial transcriptomics analysis of skin from patients with mycosis fungoides-type CTCL and an integrated comparative analysis with human skin cell atlas datasets from healthy and inflamed skin. We revealed the co-optation of T helper 2 (TH2) cell-immune gene programs by malignant CTCL cells and modeling of the tumor microenvironment to support their survival. We identified MHC-II+ fibroblasts and dendritic cells that …

Purpose: Definitive intent radiation therapy (RT) for early-stage mucosa-associated lymphoid tissue (MALT) lymphoma typically includes a dose of 24 to 30 Gy. While modest, these doses may have associated toxicity. For patients with indolent B-cell lymphoma, there is increasing support for the use of ultra-low-dose RT (ULDRT) using 4 Gy in 2 fractions as part of a response-adapted approach, as high rates of complete response have been documented. This paradigm has been prospectively evaluated in the management of orbital and gastric indolent B-cell lymphomas; however, there is limited data guiding the use of ULDRT for lung MALT.

Methods: We conducted …

Background: Shunt repair for the Norwood procedure with either the right ventricle to pulmonary artery shunt (RVPAS) or the modified Blalock-Taussig-Thomas Shunt (BTTS) varies by institution and surgeon preference. Shunt choice has been informed by landmark trials including the Single Ventricle Reconstruction trial and modern outcomes data may engender future complementary studies. Methods: We conducted a retrospective analysis of all patients who underwent the Norwood procedure from 2014–2022 at a single center to compare outcomes by shunt type. The primary outcome measure was freedom from death or transplant. Secondary outcome measures included hospital length of stay, complications, and unplanned interventions. …

Impact Of The Adenosine Receptor A2br Expressed On Myeloid Cells On Immune Regulation During Pregnancy, Stefanie Dietz, Janine Hebel, Jessica Rühle, Alisha Huff, Holger K Eltzschig, Trim Lajqi, Christian F Poets, Christian Gille, Natascha Köstlin-Gille

Faculty, Staff and Student Publications

During pregnancy, the maternal immune system must carefully balance protection against pathogens with tolerance toward the semiallogeneic fetus. Dysfunctions of the immune system can lead to severe complications such as preeclampsia, fetal growth restriction, or pregnancy loss. Adenosine plays a role in physiological processes and plasma‐level increase during pregnancy. The adenosine receptor A2B (A2BR), which is expressed on both, immune and nonimmune cells, is activated by high adenosine concentrations, achieved during pregnancy. We investigated the impact of A2BR expressed on myeloid cells on immune regulation during pregnancy using a mouse model with myeloid deficiency for A2BR. We demonstrate systemic changes …

Disease progression in clinical trials is commonly defined by radiologic measures. However, clinical progression may be more meaningful to patients, may occur even when radiologic criteria for progression are not met, and often requires a change in therapy in clinical practice. The objective of this study was to determine the utilization of clinical progression criteria within progression-based trial endpoints among phase III trials testing systemic therapies for metastatic solid tumors. The primary manuscripts and protocols of phase III trials were reviewed for whether clinical events, such as refractory pain, tumor bleeding, or neurologic compromise, could constitute a progression event. Univariable …

Nasal Virus Infection Induces Asthma Exacerbation Through B-Cell-Dependent Recruitment Of Inflammatory Monocytes, Kody A Waldstein, Arman Issimov, Maria Ganama, Valerie Jinge, Stephen Tilley, Xiaoyang Hua

Faculty, Staff and Student Publications

Background: Upper respiratory viral infections (URVIs) are responsible for 80% of asthma exacerbation episodes. However, the underlying mechanisms remain poorly understood.

Methods: In this study, we used a mouse model of URVI and examined the impact of URVI on asthma phenotypes and the underlying mechanisms.

Results: Previously, we have reported that nasal-restricted infection with respiratory syncytial virus (RSV) only produces mild sino-nasal inflammation and mucus production, without causing direct lung infection. However, such nasal-restricted infection dramatically enhanced TH2 and TH17 inflammatory responses in the lungs and increased airway hyperresponsiveness (AHR) in mice with house dust mite (HDM)-induced asthma. Additionally, nasal-restricted …

Faculty, Staff and Student Publications

Rationale and objectives: Recent ICE3 trial of breast cryoablation for breast cancer demonstrated 98% success rate, similar to breast-conserving surgery. However, ICE3 and other published studies did not differentiate curative from palliative treatment nor define patient-specific treatment objectives. We sought to define treatment success of curative and palliative breast cryoablation for breast cancer in meeting procedure objectives and patient-specific treatment objectives.

Materials and methods: We conducted a retrospective analysis of breast cancer patients who underwent breast cryoablation during 2021-2024. Breast radiologists performed outpatient cryoablation using local anesthesia and argon gas cryoprobes under ultrasound or MRI guidance. Patient demographics, referral indications, …

Faculty, Staff and Student Publications

Central nervous system-associated macrophages (CAMs) are a unique subset of immune cells located at the interface between the blood and the brain parenchyma. In a recent study in mice, Levard and colleagues found that CAMs regulate immune cell trafficking, endothelial activation, and antigen presentation following stroke exclusively in aged animals, underscoring the importance of using translationally relevant models for studying age-related diseases.

Redox Regulation Of Proteostasis, Long Duy Duong, James D West, Kevin A Morano

Faculty, Staff and Student Publications

Oxidants produced through endogenous metabolism or encountered in the environment react directly with reactive sites in biological macromolecules. Many proteins, in particular, are susceptible to oxidative damage, which can lead to their altered structure and function. Such structural and functional changes trigger a cascade of events that influence key components of the proteostasis network. Here, we highlight recent advances in our understanding of how cells respond to the challenges of protein folding and metabolic alterations that occur during oxidative stress. Immediately after an oxidative insult, cells selectively block the translation of most new proteins and shift molecular chaperones from folding …

Evaluating Novel In Silico Tools For Accurate Pathogenicity Classification In Epilepsy-Associated Genetic Missense Variants, Ludovica Montanucci, Tobias Brünger, Christian M Boßelmann, Alina Ivaniuk, Eduardo Pérez-Palma, Samden Lhatoo, Costin Leu, Dennis Lal

Faculty, Staff and Student Publications

Objective: Determining the pathogenicity of missense variants in clinical genetic tests for individuals with epilepsy is crucial for guiding personalized treatment. However, achieving a definitive pathogenic classification remains challenging, with most missense variants still classified as variants of uncertain significance (VUS) and with the availability of many computational tools which may provide conflicting predictions. Here, we aim to evaluate the performance of state-of-the-art computational tools in pathogenicity prediction of missense variants in epilepsy-associated genes. This will assist in selecting the most appropriate tool and critically assess their use in clinical setting.

Methods: We assessed the performance of nine in silico …

Guidelines On Management Of Hereditary Polyposis Syndromes In Pediatric Patients: Agreement, Disagreement And Where It Matters, Taina Hudson, Claudia Phen, Isabel Rojas, Shlomi Cohen, Warren Hyer, Thomas M. Attard

Manuscripts, Articles, Book Chapters and Other Papers

Hereditary polyposis syndromes are rare but potentially devastating conditions which require multidisciplinary care from an early age. Societal guidelines, which ideally combine expert opinions and medical evidence, serve as the framework for disease diagnosis, surveillance and treatment. However, there is a significant underrepresentation of pediatric gastroenterology input in guideline formulation, and additionally, recommendations can vary significantly between societies, which can have a moderate-to-high clinical impact on patient care. This paper aims to summarize key differences in management based on societal guidelines and identify some of the factors which may contribute to divergence in care in hereditary polyposis syndromes in pediatric …

Implementation Of A Transition-Of-Care Model For Adult Ischemic Stroke Survivors, Megan Akacsos

Electronic Theses and Dissertations

The lasting physical and cognitive deficits associated with the complexities of newly acquired

disabilities resulting from an acute ischemic stroke (AIS) may lead to hospital readmissions. The

participating healthcare facility on the U.S. West Coast reported a hospital readmission rate for

AIS survivors of 24.29% within 30 days of discharge. This doctoral nursing project aimed to

determine if implementing the Comprehensive Post-Acute Stroke Services (COMPASS) model

would reduce 30-day readmission rates compared to no standardized transition-of-care model in

adult AIS survivors over 30 days. Implementing the COMPASS model in this patient population

was expected to better educate and support stroke …
