Medical Student Research Symposium

Photoacoustic imaging is a breakthrough imaging modality that combines the spatial resolution of ultrasound imaging with the contrast of optical imaging. This imaging technique is being pushed towards clinical acceptance for many applications, such as noninvasive diagnosis and management of a multitude of neoplastic lesions. However, a rigorous evaluation of the tissue thermal response to the laser illumination is required prior to the clinical translation. In this study, we assessed the temperature rise profile and microstructural damage of the skin due to the laser-tissue interaction using in-vivo mouse models. We compared the effect of two different laser frequencies (10 Hz …

Mixed-Lineage Kinase-3 (Mlk3) Plays A Negative Modulatory Role In Insulin Secretion From The Pancreatic Β-Cell, Tyler Russeth, Vijayalakshmi Thamilselvan, Anjaneyulu Kowluru

Medical Student Research Symposium

Glucose-stimulated insulin secretion (GSIS) from the pancreatic β-cell in response to elevated levels of glucose is controlled by a variety of signals including intracellular calcium and nucleotides such as cAMP, ATP and GTP. These cellular signals are responsible for activation of specific kinases that mediate phosphorylation of key exocytotic proteins that lead to GSIS. In the context of protein kinases, mixed-lineage kinases (MLKs) have been implicated in an assortment of cellular functions, including cell proliferation and apoptosis. However, very little is known on potential regulatory roles of MLKs in islet β-cell function, including GSIS. The goal of this study is …

Krishnan M.D., Carter Batista M.D, Samir Patel M.D., Farhad Ghoddoussi Phd, Kaveh Nabavigahadi M.D., Brendan Lynch B.S.

Medical Student Research Symposium

Background: Adductor canal continuous catheters (ACCCs) have largely replaced femoral nerve continuous catheters for providing analgesia after total knee arthroplasty. Both have similar analgesic efficacy, but ACCCs preserve quadricep strength and facilitate patient mobility more quickly. We hypothesized that placing the ACCC using an out of-plane (OOP) technique would decrease pain scores and opioid use due to parallel alignment with the saphenous nerve when compared to the in-plane (IP) technique. Methods: Sixty-nine patients undergoing total knee arthroplasty were randomized to either the IP or OOP technique for ultrasound-guided ACCC. The primary outcomes of the investigation were hospital length of stay, …

Atrx Loss In Pediatric Glioma Results In Epigenetic Dysregulation Of G2/M Checkpoint Maintenance And Sensitivity To Atm Inhibition, Brendan Mullan, Tingting Qin, Ruby Siada, Carla Danussi, Jacqueline Brosnan-Cashman, Drew Pratt, Taylor Garcia, Viveka Nand Yadav, Xinyi Zhao, Meredith Morgan, Sriram Venneti, Alan Meeker, Alnawaz Rehemtulla, Pedro Lowenstein, Maria Castro, Carl Koschmann

Medical Student Research Symposium

ATRX is a histone chaperone protein recurrently mutated in pediatric glioma. The mechanism which mediates the proliferative advantage of ATRX loss in pediatric glioma remains unexplained. Recent data revealed a distinct pattern of DNA binding sites of the ATRX protein using ChIP-seq in mouse neuronal precursor cells (mNPCs). Using the ATRX peaks identified in p53^-/- mNPCs, we confirmed that ATRX binding sites were significantly enriched in gene promoters (p < 0.0001) and CpG islands (p < 0.0001) compared with random regions. Gene set enrichment (GSE) analysis identified that cell cycle and regulation of cell cycle were among the most significantly enriched gene sets (p=2.52e-16 and 1.61e-9, respectively). We found that ATRX loss resulted in dysfunction of G2/M checkpoint maintenance: (1) ATRX-deficient pediatric glioblastoma (GBM) cells exhibited a seven-fold increase in mitotic index at 16 hours after sub-lethal radiation, and (2) murine GBM cells with ATRX knockdown demonstrated impaired pChk1 signaling on western blot at multiple time points after radiation compared to controls (p=0.0187). Notably, the ATM signaling (pChk2) remained intact in those cells, suggesting a potential therapeutic target. ATRX-deficient mouse cells were uniquely sensitive to ATM inhibitors at 1 uM alongside 8 Gy radiation compared to controls with intact ATRX (AZD0156: p=0.0027 and AZD01390: p=0.0436). Mice intra-cranially implanted with ATRX-deficient GBM cells showed improved survival (n=10, p=0.0018) when treated with AZD0156 combined with radiation. Our findings suggest that ATRX loss in glioma results in unique sensitivity to ATM inhibition via epigenetic dysregulation of G2/M checkpoint maintenance.

Medical Student Research Symposium

Background:

Many African Americans (AA) are chronically infected with Hepatitis B (HBV). While antiviral therapy is highly effective, clinical trials suggest a treatment-related decline in kidney function is possible. Given that chronic HBV predominately affects Asians worldwide, most studies have contained few AA patients. We evaluated these treatment-related kidney function changes in our predominately AA patient population.

Methods:

From 225 HBV patients, we identified 42 patients who were not co-infected with HIV or HCV, had a recent visit, and at least one earlier visit (before Jan 2017). If on treatment with antivirals it must have been for at least 2 …

Quality Improvement In Ibd Care: The Influence Of A Qi Specific Conference For Fellows, Olayinka Afolabi, Alexis Faber, Raya Kutaimy, Paul Naylor, Murray Ehrinpreis

Medical Student Research Symposium

Given the complexity of management of inflammatory bowel disease (IBD), medical societies such as the American Gastroenterological Association (AGA) and Crohn’s and Colitis Foundation of America (CCFA) have established measures aimed at defining quality of care. In 2011, the AGA proposed 10 quality metrics for IBD, eight of these measures relate to outpatient management and two focus on inpatient management. Our objective was to evaluate compliance with these measures in our own general GI practice and determine whether a GI conference discussing quality improvement (QI) in 2017 was effective.

Single Vs. Multiple Laparoscopies: Pain Status One Year Post-Hysterectomy For Chronic Pelvic Pain, Ghadear Shukr, Madeleine R. Gonte, Victoria Webber, David Eisenstein

Medical Student Research Symposium

Despite the prevalence of chronic pelvic pain (CPP)— affecting one in seven women in the U.S.— its cause is often unknown. As such, an evaluation of our current approaches to the work-up of CPP is warranted. Laparoscopy is considered a gold standard tool in the evaluation of CPP with 40% of all laparoscopies in the U.S. performed for this condition [1]. However, limited data exists portraying the clinical importance and outcomes for repeat diagnostic laparoscopies. This is a retrospective case-control study to determine the incidence of multiple laparoscopies for CPP over the past 10 years, and to compare outcomes between …

Intraosseous (Io) Vs Intravenous (Iv) Vascular Access For Out Of Hospital Cardiac Arrest., Syed Tariq Nabi, Megan Mackenzie, Monica Prasad, Mustapha Choucair, Peyton Johnston, Reba John, Sarah Meram, James Paxton

Medical Student Research Symposium

Over 300,000 Americans every year experience an out-of-hospital cardiac arrest (OHCA) (Benjamin EJ 2019). Of these 300,000+ patients only 10.6% of them survive to hospital discharge. Advanced Cardiac Life Support (ACLS) has been suggested to improve survival following an OHCA (Neumar, Otto et al. 2010). Current ACLS guidelines recommend obtaining vascular access, however, offer little suggestion as to which type of access device should be used. It is our belief that using an Intraosseous vascular access device will lead to shorter time to medication delivery and increased rates of return of spontaneous circulation (ROSC) compared to Intravenous vascular access. We …
