Host-Intrinsic Factors Determine Anti-Tumor Efficacy Of Exercise In Pancreatic Ductal Adenocarcinoma, Sumedha Pareek

Dissertations and Theses (Open Access)

Pancreatic Ductal Adenocarcinoma (PDAC) is the third leading cause of cancer-related deaths with a low 5-year relative survival rate of approximately 13.3% for all stages combined. We have previously shown that exercise can improve quality of life and enhance functional capacity among patients with PDAC. Exercise induces a variety of changes in the tumor microenvironment with beneficial effects in several tumor types. However, our understanding of the clinical effects of exercise and the mechanisms that mediate anti-tumor effects are limited in pancreatic cancer.

In this project, using C57BL/6 mice from Taconic Biosciences (Tac) and Jackson Laboratories (Jax), we established a …

Assessing Cognitive Performance And Comfort Under Simulated Mri Noise And Its Association With Autistic Like Traits, Jasmin Woodhouse

The Plymouth Student Scientist

Magnetic Resonance Imaging (MRI) scanners produce noise levels between 65 and 130 decibels. This noise, alongside the broader sensory environment of the MRI, poses challenges for individuals with autism spectrum disorder (ASD). Noise exposure has been shown to impair task performance, increase errors, and affect brain activity. ASD traits are associated with decreased sound tolerance, including hyperacusis, misophonia, and phonophobia. In ASD, noisy environments disrupt inferior frontal gyrus function, impairing task response and brain connectivity. Given this, it’s crucial to understand how these sensory challenges specifically affect ASD experience and performance during MRI procedures. This study assesses cognitive performance and …

Detecting Concealed Autobiographical Information Using Feedback And Recognition P300 Erps. Exploring The Impacts Of Changed Feedback Proportions And Social Pressure In The Fcit, Cerys Parkinson-Johns, Grace Shillito, Callum Starr, Rosemary Wilmshurst

The Plymouth Student Scientist

The feedback concealed information test (fCIT) incorporates feedback on memory concealment performance within the classical CIT. Providing feedback facilitates the analysis of feedback related ERPs in addition to initial recognition related ERPs within each trial. Combining multiple ERPs aims to improve the reliability and efficiency of the test. The present study investigated the efficiency of combining recognition and feedback related P300 ERPs in detecting concealed birthdates in a personal item fCIT. Feedback proportions were altered to improve believability in feedback. Detection efficiencies using combined P300 amplitudes within this altered paradigm and the impacts of social pressures on feedback P300s were …

Examining The Correlation Between The Competing Values Framework And Other Scales Of Measure, Jesina Mistry

The Plymouth Student Scientist

Organisational culture is widely acknowledged as a critical determinant of performance and employee engagement, yet debates persist regarding how best to conceptualise and measure it. This study examines the construct validity of two widely used diagnostic tools: the Competing Values Framework (CVF) and the Organisational Culture Inventory (OCI). While the CVF has achieved broad application across sectors, questions remain regarding its empirical grounding and cross-cultural relevance. Using a quantitative, cross-sectional design, this research investigates the degree of convergence between CVF and OCI dimensions within a diverse UK-based sample spanning multiple industries and job levels. In addition, it incorporates three underexplored …

The Lived Experience Of Uk Students Transitioning To University With Type 1 Diabetes Mellitus, Emelia C. Steel

The Plymouth Student Scientist

Transitioning from secondary school to university is a high-risk period for managing type 1 diabetes among UK students. Canadian research identified limited systemic support during this period. However, there is a lack of qualitative insight into how students navigate this transition in the UK, where healthcare and education systems differ. This study addressed that gap through semi-structured interviews to understand what makes this transition particularly challenging and what support students would find most helpful. A purposive sample comprised seven participants aged 19–29 from four UK universities. Thematic analysis, guided by Braun and Clarke’s (2022) six-phase framework, identified three superordinate themes: …

Investigating Deception-Related Moral Conflict Using Electroencephalography (Eeg) Hyperscanning, Madie Ades

The Plymouth Student Scientist

Amplitudes of the early Bereitschaftspotential (BP) and deceptive behaviour have been theorised to be modulated by moral conflict experienced when making deceptive decisions, as the decision to lie can depend upon our moral perceptions of what is right and wrong (Panasiti et al., 2014). However, most Electroencephalography (EEG) deception paradigms lack ecological validity by utilising instructed lying and failing to incorporate genuine social interaction (Ganis & Keenan, 2009) and therefore may fail to elicit genuine moral conflict. The present study combined hyperscanning EEG with a competitive two-player social game, where participants freely chose to respond accurately or deceptively for …

The Association Between Condom Use Self-Efficacy And Condom-Decision Abdication Among College Students, Mikaela Gjoka, Madison K Firkey, Alan Z Sheinfil, Sarah E Woolf-King

Faculty, Staff and Students Publications

Objective: Condomless sex and its related consequences are a persistent problem on college campuses in the United States. This study aimed to examine the association between condom use self-efficacy and condom-decision abdication among college students, and whether this association was moderated by gender.

Participants & methods: Undergraduate college students (N = 212; 50.5% female) were recruited via Amazon Mechanical Turk as part of a larger online study that examined normative feedback for condom use.

Results: The association between condom use self-efficacy and condom-decision abdication was significantly moderated by gender (B = -0.07, p < .001), such that condom use self-efficacy was associated with condom-decision abdication in college women (B = -0.05, p < .005) but not in college men (B = .02, p = .18).

Conclusion: Findings from this study suggest that …

As Effective As You Perceive It: The Relationship Between Chatgpt’S Perceived Effectiveness And Mental Health Stigma, Scott N. Hannah, Deirdre Drake, Christopher D. Huntley, Joanne M. Dickson

Research outputs 2022 to 2026

Individuals are increasingly using artificial intelligence chatbots, such as ChatGPT, to seek conversational support for their personal mental health difficulties. Heightened concerns about mental health stigma may make anonymous, on-demand chatbot interactions more appealing for some than traditional face-to-face support. This study examined if using ChatGPT-4 for personal mental health difficulties is associated with two distinct forms of stigma, anticipated stigma and self-stigma. Our main aim was to investigate if the perceived effectiveness of ChatGPT use for mental health issues mediates the relationship between ChatGPT usage and anticipated stigma and self-stigma. The sample comprised 73 participants, mostly undergraduate psychology students. …

Perfectionism And Compulsive Exercise: A Systematic Review And Preliminary Meta-Analysis, Elizabeth Bills, Shannon R. Muir, Rose Stackpole, Sarah J. Egan

Research outputs 2022 to 2026

Purpose: There is a consistent link between perfectionism and compulsive exercise, and both are implicated in the maintenance of eating disorders, however no meta-analysis to date has quantified this relationship. We hypothesised that there would be significant, small-moderate pooled correlations between perfectionism dimensions and compulsive exercise. Methods: Published, peer-reviewed articles with standardised measures of perfectionism and the Compulsive Exercise Test were included. There were 7 studies included (N = 3117 participants, M age = 21.78 years, 49% female). Results: Total perfectionism (r = 0.37), perfectionistic strivings (r = 0.33), and perfectionistic concerns (r = 0.32) had significant pooled positive associations …

Schofield

Research outputs 2022 to 2026

Background: Biological studies suggest serotonin modulation via selective serotonin reuptake inhibitors (SSRIs) might reduce impulsive violence, however, robust evidence in offender populations is limited. We aimed to determine whether sertraline reduces violent reoffending compared with placebo in highly impulsive men with recurrent violent offending.

Methods: We conducted a double-blind, placebo-controlled, randomised clinical trial in community settings in New South Wales, Australia. Eligible participants were men aged 18 years or older with ≥2 prior violent convictions and a Barratt Impulsiveness Scale score ≥70. Following a 4-week single-blind active run-in phase with sertraline, participants were randomly assigned (1:1, minimization stratified by key …

Young Adults And Early-Onset Psychosis: A Grounded Theory Study Of Experiences Of Identity Development, Katherine Hayden-Lewis, Deborah Rubel

The Qualitative Report

While identity development is a crucial task for young individuals ages 15-25, current research inadequately centralizes identity development in the context of first-time psychosis related to schizophrenia spectrum disorders. This study addresses the knowledge gap by exploring the grand research question, “How does a young person experience their identity development after the first episode of psychosis?”. Constructivist grounded theory methods influenced by critical frameworks were used to collect and analyze data with seven young adults engaged in first episode psychosis programs. Participants were young adults, between the ages of 19-24, that at the time of the study were enrolled in …

Impact Of Common Variants On Brain Gene Expression From Rna To Protein To Schizophrenia Risk, Qiuman Liang, Yi Jiang, Annie W. Shieh, Dan Zhou, Rui Chen, Feiran Wang, Meng Xu, Mingming Niu, Xusheng Wang, Ramu Vadukapuram

School of Medicine Publications

Genetic variants influencing gene expression have been extensively studied at the transcriptional level. How these variants affect downstream processes remains unclear. We quantitated ribosome occupancy in prefrontal cortex samples from the BrainGVEX cohort and integrated these data with transcriptomic and proteomic profiles from the same individuals. Through cis-QTL mapping, we identified genetic variants associated with transcript level (eQTLs), ribosome occupancy (rQTLs), and protein level (pQTLs). Notably, only 34% of eQTLs have their effects propagated to the protein levels, suggesting widespread post-transcriptional attenuation. Using both a gene-based approach and a variant-based approach we identified omics-specific QTLs that associated with brain disorder …

Physician Peer Review: Just Culture And Practical Implementation In An Emergency Department, Christian Fromm, Monica Colicino, Merle A. Carter, Elizabeth M. Datner

Einstein Health Papers

BACKGROUND: Although regulatory agencies require hospitals to engage in peer review to maintain accreditation, quality assurance review processes are not standardized, and well-structured peer review of clinical cases involving medical errors and adverse events governed by Just Culture principles is not widespread. We implemented such an emergency department (ED) physician peer review process and performed an analysis of cases that underwent review.

METHODS: We formed an ED physician peer review committee at our institution guided by Just Culture principles, including promotion of a culture of safety to encourage open reporting of errors and near misses, and top-down leadership commitment to …

Genes influencing opioid use disorder (OUD) biology have been identified via genome-wide association studies (GWAS), gene expression, and network analyses. These discoveries provide opportunities to identifying existing compounds targeting these genes for drug repurposing studies. However, systematically integrating discovery results and identifying relevant available pharmacotherapies for OUD repurposing studies is challenging. To address this, we've constructed a framework that uses existing results and drug databases to identify candidate pharmacotherapies. For this study, two independent OUD related meta-analyses were used including a GWAS and a differential gene expression (DGE) study of post-mortem human brain. Protein-Protein Interaction (PPI) sub-networks enriched for GWAS …
