Anesthetic And Perioperative Challenges Of End-Stage Liver Disease In Non-Hepatic Surgery: A Case For Score-Triggered Perioperative Protocols, Katarina Rusinak Bs, Christopher Hoffman Do, Cory Levitt Md

Rowan-Virtua Research Day

Introduction: End-stage liver disease (ESLD) significantly increases perioperative morbidity and mortality during non-hepatic surgery. Although validated risk stratification tools, including the Child-Turcotte-Pugh (CTP) and Model for End-Stage Liver Disease (MELD) scores, are available, their use frequently remains limited to quantifying risk without prompting standardized perioperative protocols. This case demonstrates that elevated cirrhosis-specific risk scores should function as triggers for enhanced preparation and multidisciplinary planning, following models established in other high-risk clinical contexts.

Case Report: A 43-year-old female with decompensated alcohol-related cirrhosis was scheduled for total thyroidectomy for papillary thyroid cancer, a procedure required for liver transplant eligibility. Preoperative evaluation revealed …

Establishing Caenorhabditis Elegans As A Platform For Bioaccumulation And Selectivity Screening Of Anthelmintic Compounds, Jiarui Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

To address the cuticular barrier in anthelmintic discovery, this study establishes a bifurcated framework in Caenorhabditis elegans. First, HPLC-based quantification of 14 PIM inhibitors revealed that cuticular penetrance is primarily dictated by phylogenetic lineage (Clade V) rather than ecological niche. Specifically, C. elegans demonstrated a significant pharmacokinetic correlation with the hookworm Ancylostoma ceylanicum (Clade V) but not the whipworm Trichuris muris (Clade I), validating it as a superior surrogate model for hookworm bioaccumulation. Within this small molecule inhibitor library, SGI-12was identified as a lead candidate with superior potency against C. elegans and bioaccumulation. Second, target validation using a C. …

Evaluation Of The Effectiveness Of Antihypertensive Therapy Chosen Through Maternal Hemodynamic Profile Analysis, Margaret Weimer May 2026

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.


Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson’S Disease, Brock Renicks May 2026

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

Poster Presentations

Around 40% of people with Parkinson’s Disease experience depression and anxiety (Zhao et al, 2025). Depression and Anxiety have been said to be localized to the dorsolateral prefrontal cortex (Brunoni et al, 2016). Transcranial Direct current stimulation (tDCS) has been shown to modulate depression and anxiety by targeting the dorsolateral prefrontal cortex (Sreeraj et al, 2023). It is beneficial due to its cost, portability, and simplicity of use. Thus we will be assessing the efficacy of tDCS in reducing depression and anxiety in individuals with Parkinson’s Disease.
