Case Report: Management Of A Challenging Case Presenting With Dysphagia After Thyroidectomy Requiring Administration Of Liquid 131i Via Mic-Key Low-Profile Tube—A Multidisciplinary Approach, Ahmed Ebada Salem, Sandra Ramirez, Brian R Weston, Akram Hussein, Simone Krebs

Faculty, Staff and Student Publications

Radioactive iodine (RAI) therapy with 131-iodine (131I) remains a cornerstone in the postoperative management of differentiated thyroid carcinoma (DTC). The standard route of administration is oral, typically in capsule form and less commonly as a liquid. However, in patients with severe dysphagia and compromised airway, traditional oral 131I delivery may be contraindicated due to the risk of aspiration and radioactivity contamination. These scenarios present unique clinical challenges that necessitate deviation from conventional protocols. While liquid 131I may be administered through the mouth or via nasogastric or percutaneous gastrostomy tubes, there is currently no standardized approach, and potential risks, such as …

Bop2-Te: Bayesian Optimal Phase 2 Design For Jointly Monitoring Efficacy And Toxicity With Application To Dose Optimization, Kai Chen, Heng Zhou, J Jack Lee, Ying Yuan

Faculty, Staff and Student Publications

We propose a Bayesian optimal phase 2 design for jointly monitoring efficacy and toxicity, referred to as BOP2-TE, to improve the operating characteristics of the BOP2 design proposed by Zhou et al. (2017). BOP2-TE utilizes a Dirichlet-multinomial model to jointly model the distribution of toxicity and efficacy endpoints, making go/no-go decisions based on the posterior probability of toxicity and futility. In comparison to the original BOP2 and other existing designs, BOP2-TE offers the advantage of providing rigorous type I error control in cases where the treatment is toxic and futile, effective but toxic, or safe but futile, while optimizing …

Our optimal calibration scheme minimizes the total trial sample size while controlling incorrect decision rates at nominal levels. This calibration …

Contemporary Opportunities And Potential Of Auger Electron-Emitting Theranostics, Seok-Yong Lee, H Charles Manning

Faculty, Staff and Student Publications

Recent breakthroughs in radiopharmaceutical (RP) therapy have emerged interest in employing Auger electron (AE)-emitting radionuclides as potential agents for precise theranostics. AE provides energy with exceptional localization due to their short tissue penetration range (TPR, < 10 nm), rendering them particularly effective for targeting nuclear DNA in tumor cells. In this context, AE-emitting radionuclide therapy (AE-emitting RLT) enables the targeted destruction of tumor cells while reducing harm to adjacent healthy tissue, a significant challenge in this field. Preclinical and early clinical investigations reveal the efficacy of AE-emitting RLTs in the theranostics of diverse malignancies, such as glioblastoma, prostate cancer, and neuroendocrine tumors. Notwithstanding these developments, challenges and limitations persist regarding dosimetry, delivery efficiency, and the treatment of radiotoxicity. A new paradigm is being developed to tackle the obstacles encountered by integrating molecular target markers (e.g., PARP) that function near the nucleus to improve the intranuclear delivery efficiency of AE-emitting radionuclides. Novel radiochemical methods such as these have facilitated the more stable and efficient labeling of biomolecules with AE-emitting radionuclides. Also, recent advances in DNA-molecular targeting, nanoparticles, nucleic acid/protein engineering, click- or bioorthogonal conjugation chemistry, and artificial intelligence (AI)-based structure modeling present concrete opportunities to overcome these limitations. Moreover, the integration of diagnostic imaging companion platforms employing theranostic radioisotope pairings facilitates real-time assessment of therapeutic efficacy and biodistribution, resulting in the formulation of enhanced treatment regimens. This review summarizes the prior development, recent advancements, barriers in clinical implementation, and future perspective of AE-emitting RLTs.

NSD2 catalyses the epigenetic modification H3K36me2 (refs. 1,2) and is a candidate convergent downstream effector of oncogenic signalling in diverse malignancies3–5. However, it remains unclear whether the enzymatic activity of NSD2 is therapeutically targetable. Here we characterize a series of clinical-grade small-molecule catalytic NSD2 inhibitors (NSD2i) and show that the pharmacological targeting of NSD2 constitutes an epigenetic dependency with broad therapeutic efficacy in KRAS-driven preclinical cancer models. NSD2i inhibits NSD2 with single-digit nanomolar half-maximal inhibitory concentration potency and high selectivity over related methyltransferases. Structural analyses reveal that the specificity of NSD2i for NSD2 …

Respiratory Motion Effects And Plan Robustness For Lattice Radiation Therapy, Rachael M Martin-Paulpeter, Peter A Balter, Luis A Perles, Ethan B Ludmir, Joshua S Niedzielski

Faculty, Staff and Student Publications

Introduction: Lattice radiation therapy (LRT), a form of spatially fractionated radiation therapy (SFRT), has shown promise in treating bulky tumors. It consists of hot and cold spots within the tumor, and the ratio between these doses is thought to be important in clinical outcomes. Respiratory motion is expected to degrade these peak-to-valley dose ratios (PVDRs) but has largely been ignored in LRT literature and clinical practice. This work aims to quantify the response of LRT dose distributions to motion to better inform motion management decisions and improve clinical outcomes.

Methods: Respiratory motion of peak-to-peak amplitudes from 0.3 to 2 cm …

Grading Melanocytic Dysplasia: Updated Histopathologic Criteria, Christopher R Shea, Victor G Prieto, Catherine M Shachaf, Scott R Florell

Faculty, Staff and Student Publications

Dr. Martin C. Mihm, Jr.'s innovative work on the dysplastic nevus achieved a milestone in his chapter in the World Health Organisation Classification of Skin Tumours (WHO-C). WHO-C presents a dichotomous classification (high-grade versus low-grade dysplastic nevi) and a quantitative metric to assess melanocytic nuclear enlargement. The Duke classification is a related approach that provides mostly quantitative histopathologic criteria for dysplastic nevi and gives due weight to architectural features as well as cytology. This paper proposes and illustrates updated criteria for scoring and grading melanocytic dysplasia, incorporating some of the definitions and categories of WHO-C, while refining the quantitative and …

The Impact Of Service Learning On Social Capital And Community Engagement, Jason R. Ross

Journal of Excellence in College Teaching and Learning

Social capital is important for individual and societal advancement. For individuals, social capital helps one advance in the organizational hierarchy but also flows to communities as these individuals are more likely to volunteer for non-profit organizations and pool their resources to advance societal causes. This paper argues that one overlooked mechanism for generating social capital is through service learning. Service learning benefits students not only academically, but professionally as it helps students connect with voluntary organizations, often composed of individuals of means. Students then integrate into the social networks of these influential members and potentially benefit from the resources they …

School of Geography, Earth and Environmental Sciences

Little is known about the presence, distribution, origins and characteristics of plastic litter and microplastics on the ocean floor. In this study, plastics trawled from the bed of the western English Channel have been categorised and analysed by a variety of optical and spectroscopic techniques. A total of 90 plastic samples were classified, in descending order of abundance, as food-drink packaging, unknown, homeware, military and fishing. Most samples showed varying degrees of weathering (e.g., discolouration, distortion, cracking, fragmentation) and were visibly fouled by calcareous deposits. The majority of samples were constructed of polymers of negative buoyancy (e.g., polyamides, polyethylene terephthalate …

Enhancing Monitoring In Protected Areas: Evaluating Mobile Apps As A Tourism Proxy, Jorge Costa, Alberto Gomes, Martin Stokes, Miguel Saraiva

School of Geography, Earth and Environmental Sciences

Crowdsourced data, such as that from mobile fitness apps (MFAs), has the potential to transform tourism research. This opportunity is particularly valuable as tourism to protected areas (PAs) increases, making it more difficult to manage their environmental impacts. However, such data sources come with challenges. Therefore, their representativeness should be carefully evaluated, particularly as their use continues to grow. We use the Paiva Walkways (Portugal) to assess MFAs as a tourism proxy using Spearman’s rank correlation, to evaluate kernel density and fishnet methods for spatialising visitor movements, and to analyse the visitors’ spatiotemporal behaviour using GIS, kernel density estimation, and …

Feminism, Domestic Abuse And The Singer-Songwriter, Kathryn Ferguson

School of Art, Design and Architecture Theses

This project explores how feminism and domestic abuse can be articulatedthrough songwriting. Research in music therapy, sociology and popular musicincreasingly speaks to the value of songwriting as a tool for personal andcommunity empowerment, but there is space to actively use songwriting toexplore feminist issues independently of the traditional commercial context ofpopular music. Existing feminist music has been deemed as at its mostsuccessful when it is linked clearly to social change in our communities(Greene, 2017, p.8). Modern popular feminist songwriting has been criticised fornot going far enough in deconstructing systemic patterns of patriarchy (Tong,2024, p.9). Considering this, engaging with academic research …

Translating Human Emotion Into Music: A Multimodal Machine-Learning Framework Linking Movement, Facial Expression, And Real-Time Generative Composition, Martin Mc Corry

The research introduces a structured translation layer comprising a consensus mapping matrix and a tiered control architecture, mediating between probabilistic inference and …

The Development Of Collaborative Relationships Between Disaster Relief Ngos: Barriers And Solutions, Christopher Phillips

Plymouth Business School Theses

Collaborative responses amongst disaster relief NGOs can be more effective in delivering aid when compared with responses conducted individually. Collaboration enables the sharing of resources, expertise, personnel, and funding, resulting in more efficient aid distribution in the wake of natural disasters. However, current research highlights that it is often challenging for NGOs to establish and sustain collaborative relationships due to different barriers. The challenges these barriers cause have been explored in previous research, but limited attention has been given with respect to how these can be addressed. Additionally, there is a lack of understanding of the relationships between these barriers, …
