Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson's Disease, Brock Renicks

Honors Theses

The aim of this study is to observe the outcomes of transcranial direct current stimulation (tDCS) as a treatment for Parkinson’s Disease (PD). This study will primarily look at changes in depression and anxiety, as these symptoms are often comorbid with Parkinson’s Disease. Transcranial direct current stimulation is a non-invasive, very low-intensity form of electrical stimulation of the brain. It is being increasingly used as a form of treatment for Parkinson’s Disease and depression and anxiety, however the literature is ambiguous, showing mixed results throughout various studies, with no standardization of tDCS administration. To determine the effect of tDCS on …

Evaluation Of The Effectiveness Of Antihypertensive Therapy Chosen Through Maternal Hemodynamic Profile Analysis, Margaret Weimer

Poster Presentations

In treatment of emergent hypertension, the American College of Obstetricians and Gynecologists (ACOG) recommends both oral labetalol and nifedipine, with no preference shown between the two. These medications have different mechanisms of action. Studies have suggested that consideration of hemodynamic profile may be an effective way to determine medication, but have not considered the Rule of 55, a simple calculation to predict hemodynamic profile.

Goals: 1. Determine if tailoring the antihypertensive to patient’s hemodynamic profile is associated with better control of blood pressure. 2. Determine if the Rule of 55 is an accurate method to determine hemodynamic profile.

Adhesion Of Antibiotic-Resistant Bacteria To Thermoplastic Materials Used In Fabricating Medical Devices: Patient Consequences, Dev V. Mehta

Poster Presentations

Burn injury patients wear supportive orthoses made by heat-forming sheets of thermoplastic material (Figs. 1 & 2). Bacteria cause severe soft tissue infections in patients wearing contaminated orthoses. Thermoplastic medical devices can develop biofilms that include antibiotic-resistant (AR) bacteria, which significantly reduces the number of available treatment options. A biofilm is a community of microorganisms that share resources allowing them to exist in a nutrient-limited environment. Biofilm microbes secrete extracellular polymeric substance (EPS) that attaches them firmly to a substrate surface while protecting them from harmful substances, including antibiotics. Bacteria living within biofilms on inanimate surfaces can survive for extended …

Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta

Honors Theses

This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …

Determinants Of Hypertension Awareness And Control In Kenya: A Secondary Analysis Of National Survey Data, Alexander K. Davis

Honors Theses

In low- and middle-income countries (LMICs), cardiovascular diseases (CVDs) are prevalent and pose a major concern as the current healthcare systems are oriented primarily towards communicable diseases. The largest contributor to CVDs, hypertension, is a significant issue in Kenya, a model LMIC. Based on previous studies in this lab, high rates of hypertension are present in the region of Kasigau, Kenya. Kasigau is a small region within Taita-Taveta County, Kenya. Traditional risk factors are not necessarily predictive of hypertension in all regions of Kenya. This study aims to address the lack of tested risk factors for hypertension in Kenya and …

The Effects Of Sugammadex Vs. Neostigmine On Intraoperative Heart Rate In Pediatric Patients Under Two Years: A Scoping Review, Saumel Abston, Jackson Cobb, Elle Dean, Tanner Dillard, Pauline Dinh, Dwayne Accardo Dnp, Crna, Faana, Margaret Harvey Phd, Aprn, Acnp-Bc, Chfn, Fhrs

Doctor of Nursing Practice Projects

Purpose/Background

Neuromuscular blockade (NMB) reversal is a critical component of anesthesia care, particularly in infants under two years of age who have immature autonomic regulation and heightened vagal tone, predisposing them to bradycardia. Neostigmine, the traditional reversal agent, is associated with parasympathomimetic effects such as bradycardia, requiring anticholinergic co- administration. Sugammadex, a selective relaxant binding agent, offers rapid and predictable reversal of aminosteroidal neuromuscular blocking agents with less cholinergic side effects. Although the safety profile of sugammadex is well established in older pediatric populations, limited evidence exists regarding its cardiovascular effects in infants under two years of age.

Expanding Access To Noninvasive Spinal Neuromodulation For Pediatric Spinal Cord Injury Rehabilitation: A Comparative Device Study, Alice E C Palmer

College of Arts & Sciences Senior Theses

Paralysis following spinal cord injury (SCI) has traditionally been considered permanent due to the disruption of supraspinal input to spinal motor circuits. However, growing evidence suggests that spinal networks below the level of injury retain intrinsic motor-generating capabilities through central pattern generators. Transcutaneous spinal cord stimulation (scTS) is a noninvasive neuromodulation technique that delivers electrical stimulation through the skin to reactivate these spinal networks. Although prior studies demonstrate that scTS delivered through research-grade devices is safe and effective in adults and children with chronic SCI, clinical translation remains limited by lack of FDA-approved systems, high costs, and restricted access to …

Spectral Characterization Of Colorectal Cancer Using Excitation-Scanning Hyperspectral Imaging, Natalie Hadad

Honors Theses

Colorectal cancer is one of the most common and deadly cancers worldwide, with a lifetime risk of approximately one in twenty-three for men and one in twenty-five for women. Although early detection significantly improves survival, current diagnostic approaches such as tissue biopsy are invasive, reliant on subjective interpretation, have extended turnaround times, and risk missing flat or depressed lesions that are more difficult to detect than raised polyps. These limitations highlight the need for objective, minimally invasive technologies capable of detecting early tissue changes. This study investigates excitation-scanning hyperspectral imaging (Ex-HSI) as a label-free optical approach for identifying colorectal cancer–associated …

Novel Biomarker Discovery In Multiple Sclerosis, Manisha Gangasani

Honors Theses

Multiple Sclerosis (MS) is a chronic neuroinflammatory disorder affecting the brain, spinal cord, and optic nerve. Patients experience cognitive, motor, autonomic, and emotional symptoms that often overlap with other neurological conditions, making early diagnosis challenging. Current diagnostic criteria require evidence of lesions with dissemination in time and space. Racial disparities in MS outcomes are well documented, with Black individuals often exhibiting greater disease severity, higher relapse rates, and increased disability compared to White individuals. These differences likely reflect a combination of genetic, biological, environmental, and healthcare access factors, underscoring the need to improve early diagnosis and reduce inequities in care. …

Developing A Protocol For Non-Cellular Transplantation Of Donor Mitochondria Into Recipient Cells, Andrew Parton

Honors Theses

Tumor innervation has emerged as a critical feature of cancer progression, with increased nerve density correlating with enhanced aggressiveness, metastatic dissemination, and poor clinical outcome. However, the functional contribution of neurons to tumor biology remains incompletely defined. We recently identified the intercellular transfer of mitochondria from neurons to cancer cells as a mechanism that promotes tumor progression. We therefore hypothesized that disruption of this transfer could attenuate tumor aggressivity. To directly investigate this process, we developed an approach to isolate mitochondria from donor cells and transplant them into recipient cancer cells independently of canonical cell-cell interactions. Transferred mitochondria were tracked …

Doctor of Nursing Practice Projects

Secondhand smoke exposure can significantly worsen asthma outcomes in pediatric patients, leading to increased exacerbations and healthcare utilization. Caregivers can play a critical role in reducing secondhand smoke exposure, however sustained smoking cessation can be challenging to achieve. Two powerful healthcare interventions to assist in caregiver smoking cessation include motivational interviewing and educational handouts, however their compared effectiveness has not yet been fully reviewed. This scoping review compared the effectiveness of motivational interviewing and educational handouts in promoting smoking cessation among caregivers of children hospitalized for asthma exacerbations over the course of 90 days.

Purpose/Background

Patients with diabetes mellitus are significantly more prone to delayed gastric emptying, which can increase their risk for aspiration events in the operating room despite following standard fasting guidelines set by the American Society of Anesthesiologists (ASA). Using point-of-care gastric ultrasound, trained providers can quickly and accurately evaluate gastric volumes and risk-stratify patients based on these findings. However, these methods have not been clearly assessed in the diabetic population. The purpose of this scoping review is to map the existing evidence on the use of gastric ultrasound findings among adult patients with diabetes undergoing anesthesia.

Dexmedetomidine As An Adjuvant In Intrathecal Anesthesia Vs. Opioids - Evaluating Adverse Events: A Scoping Review, Autumn Holloman Bsn, Rn, Paige Blackstock Bsn, Rn, Rasmia Ibrahim Bsn, Rn, Chase Logan Bsn, Rn, Hunter Turner Bsn, Rn, Dwayna Accardo Dnp. Crna, Faana, Laura Reed Dnp, Aprn, Fnp-Bc, Cne, Fnap

Doctor of Nursing Practice Projects

Purpose/Background 

Spinal anesthesia is widely used in surgical practice because it provides effective anesthesia and analgesia while reducing the need for intravenous anesthesia. Opioids are commonly used as intrathecal adjuvants; however, their use is associated with adverse effects such as pruritus, postoperative nausea and vomiting (PONV), urinary retention, and respiratory depression. Dexmedetomidine, a selective α2-adrenergic agonist, has gained attention as an alternative to opioids due to its sedative and analgesic properties without the opioid side effect profile. This scoping review evaluates current evidence comparing intrathecal Dexmedetomidine and opioids as adjuvants to spinal anesthesia in adult surgical patients.
