Personalized Nutrition: Tailoring Dietary Recommendations Through Genetic Insights, Saiful Singar, Ravinder Nagpal, Bahram H. Arjmandi, Neda S. Akhavan

Kinesiology and Nutrition Sciences Faculty Research

Personalized nutrition (PN) represents a transformative approach in dietary science, where individual genetic profiles guide tailored dietary recommendations, thereby optimizing health outcomes and managing chronic diseases more effectively. This review synthesizes key aspects of PN, emphasizing the genetic basis of dietary responses, contemporary research, and practical applications. We explore how individual genetic differences influence dietary metabolisms, thus underscoring the importance of nutrigenomics in developing personalized dietary guidelines. Current research in PN highlights significant gene–diet interactions that affect various conditions, including obesity and diabetes, suggesting that dietary interventions could be more precise and beneficial if they are customized to genetic profiles. …

Single nucleotide polymorphism (SNP) interactions are the key to improving polygenic risk scores. Previous studies reported several significant SNP-SNP interaction pairs that shared a common SNP to form a cluster, but some identified pairs might be false positives. This study aims to identify factors associated with the cluster effect of false positivity and develop strategies to enhance the accuracy of SNP-SNP interactions. The results showed the cluster effect is a major cause of false-positive findings of SNP-SNP interactions. This cluster effect is due to high correlations between a causal pair and null pairs in a cluster. The clusters with a …

How Is Diagnostic Uncertainty Communicated And Managed In Real World Primary Care Settings?, Jessica Russell, Laura Boswell, Athena Ip, Jenny Harris, Hardeep Singh, Ashley N D Meyer, Traber D Giardina, Afsana Bhuiya, Katriina L Whitaker, Georgia B Black

Faculty, Staff and Students Publications

Background: Managing diagnostic uncertainty is a major challenge in primary care due to factors such as the absence of definitive tests, variable symptom presentations and disease evolution. Maintaining patient trust during a period of investigative uncertainty, whilst minimising scope for diagnostic error is a challenge. Mismanagement can lead to diagnostic errors, treatment delays, and suboptimal patient outcomes.

Objective: Our aim was to explore how UK primary care physicians (GPs) address and communicate diagnostic uncertainty in practice.

Design: This qualitative study used video and audio-recordings. Verbatim transcripts were coded with a modified, validated tool to capture GPs' actions and communication in …

Unveiling Healthcare Disparities By Addressing Historical Traumas To Build Inclusive Spaces For Marginalized Communities: An Autoethnographic Study, Helena Humphreys

Theses and Graduate Projects

This paper delves into the pervasive disparities within the healthcare system, rooted in historical injustices that are perpetuated by systemic biases, particularly affecting Black, Indigenous, and People of Color (BIPOC) communities, as well as the LGBTQIA2S+ community. Through a comprehensive literature review and autoethnographic study, the paper examines the deep-seated issues faced by these marginalized groups, including access barriers, discrimination, mistrust of healthcare providers, and the enduring impact these have on health outcomes. Historical traumas such as the Tuskegee Syphilis Study and the use of HeLa cells underscore the enduring impact of past injustices on present-day healthcare experiences. Moreover, the …

Fewer than 200 proteins are targeted by cancer drugs approved by the Food and Drug Administration (FDA). We integrate Clinical Proteomic Tumor Analysis Consortium (CPTAC) proteogenomics data from 1,043 patients across 10 cancer types with additional public datasets to identify potential therapeutic targets. Pan-cancer analysis of 2,863 druggable proteins reveals a wide abundance range and identifies biological factors that affect mRNA-protein correlation. Integration of proteomic data from tumors and genetic screen data from cell lines identifies protein overexpression- or hyperactivation-driven druggable dependencies, enabling accurate predictions of effective drug targets. Proteogenomic identification of synthetic lethality provides a strategy to target tumor …

Neuroscience-Based Harm Reduction Education For College Students In Portland, Or, Catriona Swallow

University Honors Theses

Harm reduction (HR) is a movement focused on reducing the harms of the opioid overdose crisis through education, advocacy, and community engagement. A key component of HR is naloxone, a medication which reverses opioid overdoses when administered. Due to increased fentanyl contamination, opioid overdose deaths have been on the rise among adolescents in the U.S and HR practices are crucially important at this point in time. In recent years, alternative curricula of HR education have included a neuroscience-based approach to the topic of substance use. While both traditional and alternative programs have had success increasing substance use literacy among adolescents, …

Department of Dermatology and Cutaneous Biology Faculty Papers

There have been several reports of dupilumab use and the development of CTCL; however, the risk of CTCL development has not been adequately evaluated at the population level. The objective of this study is to determine whether dupilumab administration for AD is associated with an increased risk of developing CTCL and to identify at-risk populations within this group. This retrospective cohort study used TriNetX, a deidentified medical record database including over 107 million patients, to identify eligible patients. Treatment and control groups were evaluated for the development of CTCL. Patients of any age with a documented diagnosis of AD were …

Rural Oral Health Access Disparities In New York State, Renae Williams Atkinson Dmd, Ms, Stacy Mcilduff Cfre, Hayward Derek Horton Phd

The New York State Dental Journal

Disparities in access to dental care for those whose primary/only dental insurance is Medicaid is a known issue. The infamous case of 12-year-old Deamonte Driver from Maryland brought this great need for access to private dental care through Medicaid to the fore. Yet, to this date, there has been no resource to address this great need.

Dentists accepting Medicaid fall into two categories: those who practice in federally qualified health centers (FQHC), and those who practice privately. FQHCs are known anecdotally to have long waitlists, delaying access to needed care (as in the case of Driver). This is compounded by …

Analyzing Heterogeneity In Biomarker Discriminative Performance Through Partial Time-Dependent Receiver Operating Characteristic Curve Modeling, Xinyang Jiang, Wen Li, Kang Wang, Ruosha Li, Jing Ning

Faculty, Staff and Student Publications

This study investigates the heterogeneity of a biomarker's discriminative performance for predicting subsequent time-to-event outcomes across different patient subgroups. While the area under the curve (AUC) for the time-dependent receiver operating characteristic curve is commonly used to assess biomarker performance, the partial time-dependent AUC (PAUC) provides insights that are often more pertinent for population screening and diagnostic testing. To achieve this objective, we propose a regression model tailored for PAUC and develop two distinct estimation procedures for discrete and continuous covariates, employing a pseudo-partial likelihood method. Simulation studies are conducted to assess the performance of these procedures across various scenarios. …

Faculty, Staff and Students Publications

We investigated the accuracy of International Classification of Diseases (ICD) codes for the identification of veterans with rapid eye movement sleep behavior disorder. The charts of 139 randomly sampled veterans with ≥ 1 ICD-9 and ICD-10 code(s) for rapid eye movement sleep behavior disorder were reviewed for documentation of a suspected, previous, or current diagnosis; clinical symptoms; and/or empiric treatments for this disorder. Notably, 71 (51.1%) patients with rapid eye movement sleep behavior disorder electronic diagnoses had not undergone polysomnography, and 29 (20.9%) had polysomnography reports without commentary on rapid eye movement sleep without atonia. Sleep centers are therefore encouraged …

Safety And Efficacy Outcomes Of Early Cessation Of Anti-Pd1 Therapy In Patients 80 Years Or Older: A Retrospective Cohort Study, Kylie Fletcher, Alessio Cortellini, Teja Ganta, Roma Kankaria, Haocan Song, Fei Ye, Rebecca Irlmeier, Neha Debnath, Anwaar Saeed, Maluki Radford, Asrar Alahmadi, Akiva Diamond, Christopher Hoimes, Carolyn J Presley, Dwight H Owen, Sarah Abou Alaiwi, Amin H Nassar, Giuseppe Lamberti, Fabiana Perrone, Sebastiano Buti, Raffaele Giusti, Marco Filetti, Vito Vanella, Domenico Mallardo, Tamara A Sussman, Domenico Galetta, Foteini Kalofonou, Ella Daniels, Paolo A Ascierto, David J Pinato, Caroline Nebhan, Stephanie Berg, Toni K Choueiri, Thomas U Marron, Yinghong Wang, Abdul Rafeh Naqash, Douglas B Johnson

Older patients have similar immune checkpoint inhibitor efficacy and rates of adverse events as younger patients, but appear to have decreased tolerability, particularly in the oldest patient cohort (>80 years), often leading to early cessation of therapy. We aimed to determine whether early discontinuation impacts efficacy of anti-PD-1 therapy in patients ≥80 years old. In this retrospective, multicenter, international cohort study, we examined 773 patients with 4 tumor types who were at least 80 years old and treated with anti-PD-1 therapy. We determined response rate, overall survival (OS), and progression-free survival (PFS) in patients who discontinued therapy early (< 12 months) for reasons other than progression or death. We used descriptive statistics for demographics, response, and toxicity rates. Survival statistics were described using Kaplan Meier curves. Median (range) age at anti-PD-1 initiation was 83.0 (75.8-97.0) years. The cancer types included were melanoma (n = 286), non-small cell lung cancer (NSCLC) (n = 345), urothelial cell carcinoma (UCC) (n = 108), and renal cell carcinoma (RCC) (n = 34). Of these, 102 met the primary endpoint of < 12 months to discontinuation for reasons other than death or progression. Median PFS and OS, respectively, for these patients were 34.4 months and 46.6 months for melanoma, 15.8 months and 23.4 months for NSCLC, and 10.4 months and 15.8 months for UCC. This study suggests geriatric patients who have demonstrated therapeutic benefit and discontinued anti-PD-1 therapy at less than 12 months of duration for reasons other than progression may have durable clinical benefit without additional therapy.

Mechanisms Of Neurodevelopmental Toxicity Of Topiramate, John W Steele, Vaishnav Krishnan, Richard H Finnell

Faculty, Staff and Students Publications

Prescriptions for antiseizure medications (ASMs) have been rapidly growing over the last several decades due, in part, to an expanding list of clinical indications for which they are now prescribed. This trend has raised concern for potential adverse neurodevelopmental outcomes in ASM-exposed pregnancies. Recent large scale population studies have suggested that the use of topiramate (TOPAMAX, Janssen-Cilag), when prescribed for seizure control, migraines, and/or weight management, is associated with an increased risk for autism spectrum disorder (ASD), intellectual disability, and attention-deficit/hyperactivity disorder (ADHD) in exposed offspring. Here, we critically review epidemiologic evidence demonstrating the neurobehavioral teratogenicity of topiramate and speculate …
