College of Population Health Faculty Papers

BACKGROUND: Mental rehearsal (MR), the deliberate practice of skills specific to a procedure, has been successfully used in sports and music training for decades, but has not been adopted in surgery. This narrative review explores MR's role in surgical training and clinical practice, evaluating its effectiveness in motor skill acquisition, technical and non-technical skill development, and real world clinical implementation. Our aim was to assess MR's impact on both surgical education and clinical performance, while identifying the barriers to its routine adoption in surgical training.

METHODS: We searched for relevant studies on the topic and impacts of MR in surgery …

Review: The Impact Of Insurance Policy On Glp-1 Agonist Treatment, Sunsik Chang

Harrisburg University Dissertations and Theses

This study examines how healthcare system design influences access, adherence, and financial burden associated with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in high-income countries. Through a literature review of peer-reviewed articles published between 2020 and 2025, it compares outcomes across universal and multi-payer systems. Findings reveal significant disparities. For example, the 12-month persistence reaches 68% in centralized systems like Denmark, but falls to 32–46% in the U.S., largely due to financial burdens, insurance denials, and administrative barriers. Among uninsured U.S. patients, 45% report significant financial hardship while using GLP-1 RA therapy. However, only 20% of patients enrolled in high-deductible health …

Enhancing Neuronal Viability: The Protective Role Of 10% Human Cerebrospinal Fluid In Primary Neuronal Cultures, Vineet Arora, Alicia Bernhardt, Alessandro Naopli, Mijail Serruya

Farber Institute for Neuroscience Faculty Papers

Human cerebrospinal fluid (hCSF) is a physiologically rich medium containing neurotrophic factors, signaling molecules, and essential metabolites that support neuronal development, survival, and function. While its neuroprotective properties have been demonstrated in organotypic brain slices and human iPSC-derived models, its application in primary rodent cortical neuron cultures-a foundational system for studying synaptic development and neurodegeneration-remains underexplored. In this study, we systematically evaluated the effects of hCSF supplementation on neuronal viability in primary cortical cultures derived from embryonic day 18 (E18) rat embryos. To determine the optimal concentration, we tested a range of media:hCSF ratios and identified 90:10 (i.e., 10% hCSF) …

Dynamic light scattering (DLS) and electron microscopy (EM) confirmed the formation of well-defined micelles, while fluorescence assays demonstrated efficient CO release with the use of Iridium photocatalyst under 470 …

Early Diagnosis And Detection Of Skin Cancer Using Deep Neural Network Models And Feature Extraction From Pre-Trained Cnns, Sahil Khanna

Harrisburg University Dissertations and Theses

Skin cancer is one of the most common and lethal cancer types. While accurate diagnosis at an early stage is essential for skin cancer treatment it remains difficult to achieve in many regions due to lack of sufficient dermatologists and proper diagnostic equipment. Prior studies show Convolutional Neural Network (CNN) models excel at skin lesion classification and consistently achieve better results than standard diagnostic practices. However, the focus of many studies remains confined to image-based learning while neglecting useful patient metadata that could improve prediction accuracy. This research project created a specialized CNN model to classify skin lesions and evaluated …

Survival Guide For Queer Families In Heteronormative Healthcare: Liberatory Consciousness And The Paradox Of Dependent Healthcare, A Critical Policy Discourse Analysis, Dwenna A. Holden

Electronic Theses and Dissertations

In this study I explored and analyzed how the queer experiences of an anonymous higher education institution in the western United States’ self-identified queer faculty and staff intersected with the discursive framing of the college’s dependent healthcare structure and documents. Within a critical paradigm I designed research around a high-density theoretical approach to weaving various branches of queer theory together with critical theory around policy and law in relation to queer bodies and hostile heteronormative policy environments. I arrived at solutions based in complaint, survival, and transformation. I used critical policy discourse analyses to interrogate the college’s dependent healthcare documents …

Using The Token Economy To Improve Show Rates In An Outpatient/Community Mental Health Clinic, Gertrude Nabila Ndansi

Walden Dissertations and Doctoral Studies

The type of project was a quality improvement intervention. The identified practice problem was limited appointment shows among patients with appointments. Outpatient clinics often struggle with patients not showing up for appointments. Addressing this gap was critical for improving patient outcomes and resource efficiency. The practice problem must be addressed within the context of nursing practice by enhancing access to consistent mental health care and giving patients more timely support, leading to better outcomes and overall wellbeing.

A Clinical Practice Guideline For Enhanced Rehabilitation Assessment In Poststroke Patients, Chanda Honeywood

Walden Dissertations and Doctoral Studies

This doctoral project aimed to develop clinical practice guidelines (CPG) to strengthen the assessment of poststroke patients for rehabilitation. The project sought to adopt an evidence-based approach to develop standardized recommendations that can help in the timely and appropriate rehabilitation of stroke survivors, thereby reducing the risk of long-term disability and readmissions. Stroke is a significant cause of disability and poor functional recovery, increased healthcare costs, and lower quality of life for patients occur because of poor rehabilitation assessment. While rehabilitation protocols already exist, discrepancies in patient evaluations result in intervention delays and ineffective uptake of rehabilitation programs, limiting the …

Cervical Deciduosis In Early Pregnancy Mimicking Malignancy: A Report Of Two Cases, Ajit Sebastian, Nada Salih, Shiby Jose, Tamima Al Dughaishi, Vaidyanathan Gowri

Sultan Qaboos University Medical Journal

Deciduosis is a benign condition characterised by the transformation of subepithelial connective tissue into decidual-like cells, typically occurring in response to hormonal changes during pregnancy. Although benign, cervical deciduosis may macroscopically resemble malignant lesions, leading to diagnostic uncertainty. This report presents two cases of cervical deciduosis diagnosed in early pregnancy. Both patients presented with first-trimester vaginal bleeding, and speculum examination revealed extensive wart-like lesions covering the cervix. Histopathological examination of cervical biopsies confirmed decidual changes. In pregnant women presenting with threatened miscarriage, a thorough local examination and biopsy of atypical cervical lesions are essential to exclude malignancy. As cervical deciduosis …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Protein Arginine Methyltransferase 7 (PRMT7) is the only member of the protein arginine methyltransferase protein family that monomethylates its protein substrates. PRMT7 is found in both the nucleus and cytoplasm of breast cells and is believed to play a robust role in the tumorigenesis and metastasis of breast cancer. The goal of this project is to uncover possible pathways for PRMT7 to promote cancer progression. A preliminary antibody array was performed to determine the regulation of known cancer-related proteins by PRMT7. An early-stage human breast cancer cell line, MCF-7, was transfected with plasmid pCDH1-hPRMT7-GFP to over-express PRMT7. Qualitative and quantitative …

Abstract 2587 Recombinant Expression And Purification Of A. Vinelandii Cown In E. Coli, Julie Takei, Cedric P. Owens, Katie Sanders, Neeraja Gajendran

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The goal of this project is to study the protein CowN in the diazotroph Azotobacter vinelandii (Av) in comparison to CowN in Gluconacetobacter diazotrophicus (Gd). Nitrogenase is an enzyme that catalyzes the reduction of nitrogen gas into ammonia in diazotrophic bacteria. In many diazotrophs, the protein CowN prevents nitrogenase inhibition from the environmental gas carbon monoxide (CO). Previous work studied CowN in the diazotroph G. diazotrophicus. In G. diazotrophicus, CowN binds to nitrogenase and weakens CO binding to its active site. The mechanism of CowN has only been investigated in G. diazotrophicus. Thus, we are interested in determining if CowN's …

Despite the emerging public health concern related to the use of electronic cigarette vapors (ECV), its impact on lung cancer is poorly understood. We assessed the effect of ECV on lung tumorigenesis in a mouse model of lung adenocarcinoma. Mice were exposed to either room air, combustible cigarette smoke (CCS), or ECV 2 hours daily for 8 weeks at which lung samples were harvested and studied for different outcomes. We found that CCS, but not ECV, led to a significant increase in tumor burden. Immunophenotyping of both CCS- and ECV-exposed lungs displayed pronounced pro-tumor immunosuppressive phenotypes, characterized by significantly decreased …
