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 …

METHODS: This 12-week, outpatient, phase 2, single-site (Children's Hospital of Philadelphia, Philadelphia, PA, USA), randomised, 2 × 2 factorial clinical trial recruited individuals aged 10–40 years with an ejection fraction of 45% or greater who were able to exercise. A …

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.

Doctor of Nursing Practice Projects

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.

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.

Doctor of Nursing Practice Projects

Background

Psychosis in adults is a serious psychiatric condition that often necessitates inpatient hospitalization for stabilization and the initiation of medication. Untreated psychosis can lead to poor outcomes, including longer hospital stays, loss of occupational functioning, and a decreased quality of life. While antipsychotic medications are typically the first line of treatment, they can have severe side effects, which may lead to patients discontinuing their use. Cognitive Behavioral Therapy (CBT) for psychosis is an evidence-based intervention that targets maladaptive behaviors associated with the condition. CBT may improve treatment responses when used alongside antipsychotic medication. However, there is limited research on …

Mapping The Evidence On The Maternal–Fetal Triage Index (Mfti): A Scoping Review, Taylor Harris, Kelsey Downie, Margaret Harvey Phd, Aprn, Acnp-Bc, Chfn, Fhrs

Doctor of Nursing Practice Projects

Purpose/Background

Maternal morbidity and mortality remain persistent challenges in the United States, with obstetric triage serving as a critical point of entry for timely recognition and management of high-acuity maternal-fetal conditions. Despite recommendations for acuity-based triage models, many obstetric units continue to rely on non-specific emergency triage tools, such as the Emergency Severity Index (ESI), which inadequately account for pregnancy-specific physiological changes and fetal status. To address these limitations, the Association of Women’s Health, Obstetric and Neonatal Nurses developed the Maternal-Fetal Triage Index (MFTI), a five-level obstetric-specific triage tool. Although the MFTI has been increasingly adopted in clinical practice, the …

The Role Of Intravascular Ultrasound Imaging In 30-Day Readmissions Among Acute St-Elevation Myocardial Infarction Patients, Britta Watson

MUSC Theses and Dissertations

Cardiovascular disease (CVD) remains one of the leading causes of death in the United States. Coronary artery disease (CAD) is the largest contributor to deaths that result from cardiovascular disease. When CAD is left untreated, it can result in an acute ST elevation myocardial infarction (STEMI). To treat coronary blockages caused by CAD, a percutaneous coronary intervention (PCI) is performed. A PCI is a non-invasive procedure that uses coronary balloons and stents to open a narrowed or blocked coronary artery and restore blood flow.

An acute ST elevation myocardial infarction (STEMI) is a major cause of early hospital readmissions. Technological …
