Introduction

• Pancreatic ductal adenocarcinoma (PDA) is the third leading cause of cancer-related death in the US.

• PDA is resistant to conventional chemotherapy; however, mechanisms that contribute to this chemoresistance are not well-described.

• The tumor microenvironment in PDA has a dense stromal reaction, which is thought to result in low oxygen and low nutrient conditions (Feig, C., et al. 2012).

• Isocitrate Dehydrogenase 1 (IDH1) has been identified as an enzyme that plays an important role in chemoresistance in PDA (Zarei, M., et al. In progress).

• We sought to establish an IDH1 knockout cell line to further …

Cannabinoid Receptor Type-2 Modulates Nociceptive Signaling Molecules In A Model Of Post-Concussion Headache, Jarred M. Stratton, Lan Cheng, Ashley L. Tyburski, Jessica Perino, Melanie B Elliott

Abstract

The goal of this study was to investigate the role of the cannabinoid receptor type-2 (CB₂R) in the trigeminal pain pathway in a model of post-concussion headache. Sprague Dawley rats were randomized to receive either a repeated mild closed head injury (CHI) or served as incision controls. Changes in CGRP, nNOS, and IBA-1 were assessed in the trigeminal nucleus caudalis (TNC) and trigeminal ganglia via IHC. A subset of CHI rats received either a cannabinoid receptor type 2 (CB₂R) anti-inflammatory agonist (JWH133), an NSAID (Ketorolac), or vehicle and underwent von Frey testing for trigeminal allodynia. …

Surgical Apgar Score (Sas) Predicts Perioperative Morbidity And Length Of Stay In Patients Undergoing Esophagectomy At A High-Volume Center, Danica Giugliano, Md, Andrew Morgan, Francesco Palazzo, Md, Nathaniel R. Evans Iii, M.D., Ernest L Rosato, Md, Adam C. Berger, Md, Benjamin E Leiby, Phd

Department of Surgery Posters

Background:

Esophagectomy is a procedure that carries considerable morbidity. Many studies have evaluated factors to predict patients at risk and improve clinical outcomes. The aim of this study was to determine whether the SAS predicts complications, length of stay, and anastomotic leak for patients undergoing esophagectomy at a high-volume institution.

Effects Of Diabetes Mellitus And Chronic Kidney Disease On Major Outcomes In Patients Undergoing Cardiac Surgery, Mark W. Berguson, Jordan E. Goldhammer, Hong Liu, Rohinton Morris, Jianzhong Sun

Department of Anesthesiology Posters

Introduction:

• Diabetes mellitus (DM) is the leading cause of chronic kidney disease (CKD). CKD typically manifests in late stages of DM.

• DM and CKD are prevalent in patients with cardiovascular disease.

• The impact of concurrent DM and CKD on major adverse cardiocerebral events (MACE) in patients undergoing cardiac surgery remains unclear.^1,2

Objective:

To determine the effect of DM and CKD on major outcomes in patients undergoing cardiac surgery.

Effects Of Preoperative Aspirin On Major Outcomes In Graded High-Risk Patients Undergoing Cardiac Surgery, Qian Ding, Eric Yuen, Mark Berguson, Hong Liu, Linong Yao, Jordan E. Goldhammer, Jianzhong Sun

Department of Anesthesiology Posters

Introduction:

• Among patients with cardiovascular disease, nearly 70% take preventive aspirin.¹
• The benefits of aspirin are greater as a patient’s risk of cardiovascular events increases; patients with a lower risk of cardiovascular events derive less of a benefit from aspirin.²
• The effect of aspirin in surgical patients has not yet been investigated, in particular if there is an optimal effect based on operative risk when undergoing cardiac surgery.

Objective:

To determine the effects of preoperative aspirin on major outcomes after cardiac surgery in patients with low, medium, and high predicted operative mortality as determined by the EuroSCORE risk …

Preoperative Aspirin And Major Perioperative Outcomes In Patients With Hypertension Undergoing Cardiac Surgery, Qian Ding, Eric Yuen, Mark Berguson, Hong Liu, Linong Yao, Rohinton Morris, Jianzhong Sun

Department of Anesthesiology Posters

Introduction:

• Hypertension is prevalent in patients undergoing cardiac surgery and associated with a higher incidence of cardiovascular complications.
• Aspirin has been shown to prevent cardiovascular events in patients with a high risk of cardiovascular disease.
• Very few studies have investigated aspirin and hypertension, particularly its effects on major outcomes in hypertensive patients undergoing cardiac surgery.^1,2

Objective

To determine the effects of preoperative aspirin on postoperative outcomes for patients with hypertension undergoing cardiac surgery.

To examine the impact of chronic kidney disease and heart failure superimposed with hypertension on outcomes after cardiac surgery.

Dual Kidney Allocation Score: A Novel Algorithm Utilizing Expanded Donor Criteria For The Allocation Of Dual Kidneys In Adults, Adam P. Johnson, Md, Mph, Thea P. Price, Md, Benjamin E Leiby, Phd, Cataldo Doria, Md, Phd, Facs

Department of Surgery Posters

Background:

Dual kidney transplantation (DKT) of expanded criteria donors is a cost intensive procedure to help increase the pool of available deceased organ donors. In studies to day, expanded criteria single kidney (eSKT) or dual kidney transplantation (DKT) have demonstrated equivalence, but a more rigorous allocation system is needed to optimize limited resources for improved operative outcomes.

Evaluating The Sensitivity Of The Nanostrong Ncounter® Analysis System To Determine Gene Expression Changes Associated With Chemotherapy Treatment, Katerina Dukleska, Md, Christopher W. Schultz, Bs, Mahsa Zarei, Phd, David Mckeown, Md, Charles J. Yeo, Md, Jonathan Brody, Phd, Jordan M. Winter, Md

Department of Surgery Posters

Introduction

• Pancreatic ductal adenocarcinoma (PDA) remains a deadly disease with a 5-year survival of 8% for all stages combined (Siegel RL et al.). Currently, it’s the third leading cause of cancer-related deaths in the United States and by 2020 it is projected to become the second leading cause (Rahib L, et al).
• The poor prognosis in PDA is in part due to the limited therapies that are currently available.
• This highlights the importance of high-throughput technologies for gene expression analyses and drug screens.
• A recently developed NanoString Technologies nCounter® analysis system, an example of high-throughput technology, utilizes a color-coded barcode …
