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 …

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

Play To Win: A Randomized Controlled Trial To Assess The Effects Of Play-Based Training On Upper Extremity Function In Children With Hemiplegia, Vivian London

Honors Scholar Theses

Hemiplegia, or paralysis of one side of the body, is the primary symptom of unilateral cerebral palsy, a subtype of cerebral palsy, the most common movement disorder in children. Standard of care is regular physical and occupational therapy to improve performance in bimanual activities, but conventional therapy can be expensive and draining for caregivers and children, so a need exists for a novel intervention that can take place at home and that is economical for families while being engaging for children. This thesis reports data from a subset of ten children seen as part of a randomized controlled clinical trial …

Sepsis As An Immune Continuum: Cytokine Storm To Lymphopenia And Pics, Chelsey King

Senior Honors Theses

Sepsis is a leading cause of morbidity and mortality worldwide, driven by a dynamic immune continuum that progresses from early hyperinflammation to profound immunosuppression. This review examines the three overlapping phases of sepsis: the inflammation-mediated cytokine storm driven by dysregulated PRR activation, NF-κB signaling, and NETosis; apoptosis-driven lymphopenia involving caspase-mediated lymphocyte death, dendritic cell dysfunction, and metabolic exhaustion; and prolonged immunoparalysis culminating in persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Key mechanisms linking these phases, including the co-existence of hyper- and hypo-inflammatory states, are synthesized alongside relevant clinical biomarkers such as IL-6, HLA-DR, and single-cell immune profiles. This review highlights …

Co-Location Of Substance Use Disorder Treatment And Hospital Emergency Departments, Leila Hasan

Honors College Theses

Patients with substance use disorder (SUD) rely heavily on the hospital emergency department (ED) for acute care and are often discharged from the ED without access to long-term recovery resources. This project explores the impact of co-located addiction treatment programs with hospital EDs on recovery outcomes of patients with SUD. A systematic literature review conducted on relevant studies indicates that co-located programs can be effective in increasing treatment initiation and maintenance, reducing ED revisits, and reducing repeated overdose in SUD patients. Programs that were most effective included three key elements: fast linkage of SUD patients to program staff in the …

Dementia Detection In Low-Resource Languages: Evaluating Translation-Assisted Transfer Learning For Multilingual Clinical Assessment, Kylar A. Deloach

Honors Theses

Alzheimer's disease (AD) is a growing global health concern, with millions of people affected worldwide and cases expected to rise significantly in the coming decades. Early detection is critical for patient treatment and care, and recent advances in natural language processing (NLP) have shown promise in identifying linguistic markers associated with AD. However, most existing work has focused on English, leaving speakers of other languages with limited access to such tools. This study investigates how effective AD detection models trained on English data are at transferring to Greek, a low-resource language with limited dementia-related speech data available. We propose a …

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.

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.

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.

Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem

Dartmouth College Ph.D Dissertations

Surgical resection remains to be the cornerstone of treatment for most solid tumors, where the primary objective is to remove all visible and microscopic disease. However, the extent of tumor resection is inherently limited by the surgeon’s ability to distinguish tumor from normal tissue, intraoperatively. As a result, positive surgical margins (PSM), where residual tumor remains after surgery, are a common occurrence and are associated with increased recurrence, need for adjuvant therapies, dismal patient outcomes, and high healthcare costs.

Fluorescence guided surgery (FGS) has emerged as a promising technique to enhance intraoperative visualization of tumors and may help reduce the …

Optimizing Glycemic Control In Type Ii Diabetes: Continuous Glucose Monitoring : A Scoping Review, Sarah Poe, Bsn, Rn, Bailey Li, Bsn, Rn, Tracy Mcclinton, Dnp, Aprn, Ag-Acnp-Bc, Hget-C, Ebp-C

Doctor of Nursing Practice Projects

Purpose/Background

Individuals with Type II diabetes mellitus (T2DM) experience increased risk of cardiovascular disease and higher mortality rates relative to non-diabetic populations. Continuous glucose monitoring (CGM) enables more precise analysis of glucose patterns and trends compared to conventional self-monitoring of blood glucose (SMBG). CGM provides frequent measurements and generate meaningful metrics, such as time in range (TIR), time above range (TAR), and time below range (TBR), allowing evaluation of glucose stability and variability. Despite these advantages, evidence comparing CGM and SMBG remains inconsistent. This scoping review aims to evaluate how CGM compares with SMBG across reported outcomes, including TIR, TAR, …

Rothman Institute Papers

BACKGROUND: With an annual volume of total knee arthroplasties (TKAs) in the United States projected to exceed 1.5 million by 2050, optimizing perioperative pain control and facilitating early discharge remain clinical priorities. This study evaluated the effectiveness of liposomal bupivacaine (LB) vs conventional bupivacaine/ropivacaine in opioid-naïve patients undergoing primary TKA, comparing/contrasting: (1) pain score improvements, (2) opioid usages, (3) functional recoveries, and (4) hospital lengths of stay.

METHODS:  Data from the Innovations in Genicular Outcomes Research (iGOR) registry were used to identify patients undergoing unilateral primary TKA between September 2021 and December 2024. Two hundred twenty-five patients were analyzed, 42 …

Mechanisms Of Binding And Immune Escape Resistance For Broadly Neutralizing Antibodies Targeting Distinct Conserved Sars-Cov-2 Spike Epitopes: A Hierarchical Approach Integrating Mutational Profiling And Energy Landscape Analysis, Mohammed Alshahrani, Will Gatlin, Max Ludwick, Lucas Turano, Brandon Foley, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The continued evolution of SARS-CoV-2 has enabled an escape from most monoclonal antibodies, yet a subset of broadly neutralizing antibodies targeting three newly identified super-conserved RBD epitopes—SCORE-A, SCORE-B, and SCORE-C—retains remarkable activity against even the most recent JN.1-derived sublineages. Here, we employed an integrated computational framework combining conformational dynamics, mutational scanning, MM-GBSA binding energetics, and frustration profiling to dissect the molecular mechanisms by which XGI antibodies achieve broad neutralization and resistance to immune escape. Structural analysis revealed that all three SCORE epitopes share a common architecture: a highly conserved, minimally frustrated core that provides stable anchoring, flanked by peripheral regions …

Home-Based Vs Clinic-Based Stool Testing For Detecting Early Cancer Markers: A Scoping Review, S. Elizabeth Brock, Jacqueline Giles, Sydney James, Cha'landria Mccall, Bobby Bellflower Dnsc, Nnp-Bc-Faanp, Fnap, Faan

Doctor of Nursing Practice Projects

Purpose/Background 

Colorectal cancer (CRC) remains a significant public health concern in the United States, with screening rates below national targets due to persistent socioeconomic and structural barriers, particularly among underserved populations. Stool-based screening modalities offer accessible alternatives to colonoscopy, and emerging evidence suggests that home-based delivery models may improve screening uptake; however, implementation strategies vary and comparisons between home-based and clinic-based approaches remain limited. This scoping review examines current evidence on strategies that support CRC screening uptake, with a focus on stool-based modalities, including fecal immunochemical testing (FIT), fecal occult blood testing (FOBT), and multitarget stool DNA testing (mDNA), and …

How Does Cognitive Behavioral Therapy (Cbt) And Antipsychotics Compare To Antipsychotics Alone Impact Inpatient Length Of Stay: A Scoping Review, Morgan E. Johnson, Hailey M. Wade, Y'Esha V. Williams-Click, Rocquell Duncan, Laura Reed Dnp, Aprn, Fnp-Bc, Cne, Fnap

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 …
