Mycobacterium Shimoidei: A Case Report Of A Rare Nontuberculous Mycobacterial Infection In An American Patient With A Favorable Outcome, Madison Baker, Farah Majdoub, Asad Nasir

Advances in Clinical Medical Research and Healthcare Delivery

Non-tuberculous mycobacteria (NTM) are common environmental pathogens, but they are an uncommon cause of illness. One such mycobacteria, Mycobacterium shimoidei, was discovered in 1968 and found to cause a respiratory illness in 1975. Since then, fewer than 100 cases have been reported worldwide. Symptoms can include cough, fever, weight loss, and hemoptysis This report describes an American patient with no travel history who was found to have significant pulmonary disease caused by this rare non-tuberculous mycobacteria.

We determined patient-level policy impacts using 1:1 genetic algorithm matching of policy-affected patients with historical control patients and Kaplan-Meier analysis and inverse …

Dynamics Of The Airborne Phase In Discus Throwing, Andreas Maheras

Track and Field Faculty Publications

From a mechanics point of view, the execution of the airborne phase in discus throwing can affect the execution of the delivery phase, and eventually the distance thrown. It is not very important to minimize the time it takes to complete the airborne phase or how fast the thrower turns in the middle. The important element in this phase is to create the conditions for a quick planting of the left foot in the front of the ring, while at the same time keeping the shoulder axis towards the thrower's right in the final double support phase. That, can be …

Investigating The Effects Of Novel Hexylamine Compounds On Hn6 Carcinoma Cell Survival, Lydia Neven '27, Dominic Pittman '26

Annual Student Research Poster Session

Cancer is a broad term encompassing hundreds of distinct diseases, each arising from unique genetic and environmental factors. Because of this diversity, there is a continual need to develop new chemotherapies. Oral cancer, in particular, remains one of the most common cancers worldwide, yet effective therapeutic options for this malignancy remain limited. Although billions of dollars are invested annually in cancer drug discovery in the United States, the process of evaluating and advancing candidate compounds often represents a critical bottleneck, leading many promising therapies to be abandoned before their full potential is understood. In collaboration with the Hansen lab, we …

Effects Of Peripheral Sympathetic Denervation On Phytohemagglutinin (Pha) Induced Cutaneous Swelling In The Hock And Tail Of Mice, Ayusha Pokharel '27, Masyn Naegele '26

Annual Student Research Poster Session

The sympathetic nervous system (SNS) carries stress signals directly to the site of injury and activates the immune system via direct neuronal innervation or release of systemic hormones. 6-hydroxydopamine (6-OHDA) is a neurotoxin that causes denervation of the SNS by eliminating the peripheral nerve terminals, which are responsible for sending the stress signals. The effect of sympathetic denervation on the localized immune response is unexplored in the literature. Therefore, our study aims to investigate the effect of 6-OHDA-induced sympathetic denervation on local inflammation following phytohemagglutinin (PHA)-induced swelling. Even under resting circumstances, some baseline level of stress is communicated to the …

Hootation: A Gui And Api Library For Ontology Validation And Verbalization., Muhammad Amith, Xubing Hao, Warren Manuel, Manqi Li, Shun Rao, Kirk Roberts, Hua Xu, Yang Gong, Frank Manion, Cui Tao, Licong Cui

Faculty, Staff and Student Publications

Ontology verbalization refers to the process of translating formal axioms into natural language expressions. The primary objective is to facilitate the review and validation of ontology content by subject matter experts without requiring extensive technical expertise. While previous approaches based on templates or controlled grammar have been effective, they often face limitations in scalability, fluency, and adaptability. To address these issues, we developed Hootation, an open-source software system that supports ontology verbalization through both a graphical user interface and an API library. The tool implements rule-based translation of OWL2 axioms and further incorporates optional Large Language Model (LLM) components for …

Faculty, Staff and Student Publications

Introduction: Most Alzheimer's disease (AD) risk variants identified by genome-wide association studies (GWAS) reside in noncoding regions, complicating causal interpretation.

Methods: We developed PRISM-xQTL (Pleiotropic Relationships Integrated with System-level Multiomic QTL), integrating pleiotropy, co-localization, Mendelian randomization, and mediation analyses across multiomic quantitative trait loci (QTLs; expression QTL [eQTL], methylation QTL [meQTL], splicing QTL [sQTL], proteomic [pQTL], single-cell [sc-eQTL]). Seventy pleiotropic single-nucleotide polymorphisms (SNPs) shared between AD and 11 immune disorders were analyzed. AlphaGenome assessed functional regulation, and The Alzheimer's Cell Atlas (TACA) database was used for drug-target relevance of FCER1G.

Results: Across 54 Genotype-Tissue Expression (GTEx) tissues, 410 SNP-gene-tissue co-localizations …

Inferring High-Fat Dietary Patterns From Electronic Health Record Data Using Machine Learning, Ya-Yun Yeh, Hsin-Yueh Lin, Jingchuan Guo, Ramon C Sun, Sizun Jiang, Jiang Bian, Hao Dai

Faculty, Staff and Student Publications

Objectives: Electronic health records (EHRs) rarely capture dietary detail, limiting diet-disease research. We aimed to develop machine learning (ML) computable phenotypes to identify high-fat diet (HFD) using variables typically available in EHRs.

Materials and methods: We used National Health and Nutrition Examination Survey (NHANES) 1999-2020 data, where 24-h dietary recall served as ground truth. Dietary fat intake was summarized into a score (0-30) based on percent energy from fat, carbohydrate, and protein; lower scores indicated HFD. We defined HFD at cutoffs of 10, 15, and 20, and trained ML models (Extreme Gradient Boosting, logistic regression, random forest) using EHR-compatible variables …

Research suggests that sleep disturbances are common among people who use psychostimulants, including cocaine use and methamphetamine use. These sleep disturbances hinder recovery, heighten relapse risk, and worsen physical and mental health outcomes. This study aimed to estimate the prevalence and severity of insomnia among individuals who use cocaine and methamphetamine and to explore potential psychological factors that are associated with more severe insomnia. The sample included participants who completed in-person screening assessments for ongoing studies at an outpatient research clinic. As a part of this screening, participants completed the Insomnia Severity Index (ISI) and validated assessments of psychological domains …

Mindfulness Approach Used To Reduce The Impact Of Internalized Psychopathology: Anxiety And Depression, Taniyah Drayton

The Kean Review: Journal in Student Research

The emergence of mindfulness practices has increased in medical spaces throughout recent years. Mindfulness was once seen strictly for its spiritual origins, yet beginning in the late 20th century it began being assessed for its reliability in treating individuals who experienced extreme levels of pain and stress. Its origin “is often spoken of as ‘the heart of Buddhist meditation,’” as Kabat-Zinn discusses (Kabat-Zinn, 2011). Kabat-Zinn, founder of the Stress Reduction Clinic at the University of Massachusetts Medical School, introduced a new translation for mindfulness in 1979 through highlighting the skills individuals can learn and apply throughout their daily life. Kabat-Zinn …

Institute for Human Development, East Africa

BACKGROUND. Susceptibility to HIV-1 infection varies between individuals, but the biological determinants of acquisition risk remain poorly defined.

METHODS. We conducted a case-control study nested within a high-risk cohort in Kenya. We compared the plasma extracellular RNA collected before HIV-1 acquisition with that from matched uninfected individuals acting as controls to identify immunological processes linked to infection risk.

RESULTS. Individuals who later acquired HIV-1 exhibited upregulation of immune processes that facilitate viral infection, including T cell suppression and type II IFN and Th2 immune responses. In contrast, processes associated with antiviral defence and tissue repair, such as …

Older Adults And Suicide: Protective Pathways To Apply Shores In Counseling, Anna A. Ellenson, Jenny L. Cureton

Adultspan Journal

Older adult suicide (OAS) is a growing concern as the U.S. population continues to age and access to counseling expands. Despite legal and ethical requirements, counselors are often underprepared to address suicide in later life, especially through the lens of suicide protective factors (SPFs). This conceptual article introduces SHORES, a research-informed mnemonic (Skills and strategies for coping, Hope, Objections to suicide, Reasons for living/Restriction of means, Engaged care, and Support), to help counselors assess, intervene, and plan treatment with older adults. We review literature on OAS, highlight gaps in counselor training, and provide an application guide for using SHORES with …

Supporting Latine Older Adults’ Nutrition And Physical Health Goals In Counseling, Zachary Mcniece, Jacqueline Bergman

Adultspan Journal

Latine older adults face disproportionate risk of chronic nutrition-related conditions and food insecurity, which can exacerbate or contribute to mental health-related concerns. Cultural stigma toward mental illness can result in Latine clients, especially older adults, somatizing symptoms and focusing on physical health goals in counseling. Despite these intersecting needs, counselors often overlook their clients' physical health goals due to limited training and the assumption that medical providers alone should address these needs. This article advocates for the integration of basic, culturally responsive nutrition information into counseling practice to support client well-being while remaining within the scope of practice. We offer …

Controlled Antibiotic Release From Emulsion-Loaded Alginate And Fibrin Hydrogels Using Ultrasound, Ziba Ghareh Nazi Fam, Asia Winslow, Mario Fabiilli, Sam Varghese, Brian Oeffinger, Flemming Forsberg, Noreen Hickok, Lauren Delaney

Department of Radiology Faculty Papers

Postoperative infections remain a major complication after spinal fusion surgery, often caused by biofilm-forming bacteria that resist short-term antibiotic prophylaxis. Vancomycin (VAN) is sometimes delivered locally during surgery; however, levels diminish rapidly, leaving patients vulnerable to late-onset infections. We developed a composite hydrogel integrating perfluorohexane-based emulsions within alginate or fibrin matrices to enable both sustained and ultrasound-triggered VAN release. Water-in-oil-in-water emulsions were prepared using fluorosurfactant-stabilized perfluorohexane as the volatile oil phase, then embedded in hydrogels and exposed to ultrasound (2.5 MHz, 5.5 MPa peak negative pressure) to initiate acoustic droplet vaporization for triggered release. Drug release was quantified spectrophotometrically and …

Faculty and Staff Publications

Key Points:

1. Cardiovascular-kidney-metabolic (CKM) is a global public health problem; however, its mediators remain poorly known, in part due to the lack of a reliable animal model.

2. A combination of high fat and adenine diet recapitulate some of the CKD and metabolic phenotypes of CKM.

3. This model also demonstrates myocardial fibrosis and peripheral artery disease with sex-based differences and can be leveraged to probe mechanisms of CKM.

Background: Cardiovascular-kidney-metabolic (CKM) syndrome is a public health problem in the United States and results in premature cardiovascular disease at a relatively preserved GFR. The molecular mediators of CKM are poorly understood, partly …
