Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md

Medical Student Research Symposium

Background: Deltoid muscle function is central in reverse total shoulder arthroplasty (RTSA) function; however, there is limited information available regarding changes in deltoid activity before and after surgery. Few tests exist to evaluate specific muscle metrics pre and post operatively. Surface Electromyographic (EMG) is non-invasive and allows for observation of motions with multifaceted analysis of movement with minimal patient demand. Understanding the changes in shoulder muscle activation, namely in the deltoid, in patients pre and post-RTSA can further advance understanding of the procedure and rehabilitation efforts.

Methods: Nine individuals were recruited for this study: all patients underwent RTSA by a …

Methods: Active members of the American Society of Anesthesiologists (ASA) were sent an online questionnaire. Survey items included demographic information in addition to questions about measurement of preoperative anxiety, management of anxiety, and which entities were allocated responsibility to reduce patient anxiety. Data were collected from February to March 2019. Results: Of 3,661 respondents, most asked their patients about preoperative anxiety (n=2332, …

Ultrasound-Guided Out-Of-Plane (Oop) Adductor Canal Continuous Catheter Placement Compared To In-Plane (Ip) Placement In Total Knee Arthroplasty: A Randomized, Single Blinded, Pilot Clinical Trial, Sandeep H. 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, …

Inflammatory Markers In Bicuspid Transcatheter Aortic Valve Replacement, Molly N. Pantelic, Paul Nona, Dee Dee Wang

Medical Student Research Symposium

Background

Aortic stenosis (AS) has a prevalence of 2%. Valve replacement is the definitive treatment for AS, with transcatheter aortic valve replacement (TAVR) offering a minimally invasive alternative to surgery.

Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality. BAV patients are predisposed to AS, and comprise a distinct, younger TAVR patient population. Given limited prior work on inflammatory markers for TAVR risk assessment, this study sought to investigate if white blood cell count (WBC) correlates with BAV TAVR patient severity and post-TAVR outcomes.

Methods

A single-center retrospective analysis was performed on patients with BAV who underwent TAVR …

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.

Post-Surgical Pyoderma Gangrenosum After Breast Surgery: A Case Series, Jahan Tajran, Daniella Anderson, Arif Chaudhry, Dennis Hammond

Medical Student Research Symposium

Background:

Pyoderma gangrenosum (PG) is a rare inflammatory cutaneous disorder that is thought to be due to innate immune system dysfunction, specifically of neutrophils. PG has been well documented in patients with autoimmune disorders like Ulcerative Colitis and Rheumatoid Arthritis. PG can also present in surgical patients, imitating a potential wound infection and necrotizing fasciitis. Although PG is a diagnosis of exclusion, prompt recognition is essential to attaining desired aesthetic outcomes, especially with breast involvement. We present a case series of four patients who developed PG following breast surgery. We analyze each patient’s medical history, symptoms, wound progression and management …

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.

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 …

Sex-Based Differences In Depth Of Soft Tissue At The Proximal Tibia Intraosseous Catheter Insertion Site, Tristan Lemon Bs, Revelle Gappy Bs, Ryan Kelly Bs, Kenneth Kutschman Bs, Sarah Meram Ms, James Paxton Md, Mba

Medical Student Research Symposium

Background

Intraosseous (IO) catheters are commonly used to rapidly obtain vascular access for critically-ill patients in the emergency department (ED). Although the proximal tibia (PT) is a standard IO insertion site for adult subjects, little is known about sex-based variation in the proper depth of insertion.

Methods

A retrospective cohort study was performed, utilizing CT scans obtained from DMC over a ten-year period (2009-2018) to estimate soft tissue depth overlying the recommended PT-IO insertion site. Depths of soft tissue from skin surface to bone surface (Measurement A) and from skin surface to the opposite bony cortex (Measurement B) were measured …

Pannus Sign On Ultrasound And Magnetic Resonance Imaging Predicts Placenta Percreta And Is Associated With High Estimated Blood Loss, Karin Fox, Tushar Shetty

Medical Student Research Symposium

Objective: Antenatal identification of the placenta accreta spectrum (PAS) has been estimated to be approximately 50% in multicenter and population based data, with sensitivity and specificity far lower than that reported from referral center cohorts. Easily obtained, objective markers are key to improving antenatal detection. We noted that in many PAS cases, the placenta bulges over the cervical os, like an abdominal pannus over a belt. The depth of the “pannus” can be measured on ultrasound (US) and magnetic resonance imaging (MRI). We predicted that a positive sign can differentiate between percreta and increta/accreta.

Study Design: Retrospective chart review of …

Upper-Extremity Injuries Are The 2nd Most Common Workplace Injuries From 1992 To 2018, Nikhil R. Yedulla, Dylan S. Koolmees, Eric B. Battista, Syed S. Raza, Zachary A. Montgomery, Charles S. Day

Medical Student Research Symposium

Musculoskeletal injuries occur frequently in the workplace, yet it is unclear whether upper-extremity, lower-extremity, or trunk injuries are the most prevalent. We hypothesize that: (1) trunk injuries are the most common in the overall workplace, and (2) upper-extremity injuries are more common in labor-based industries than non-labor industries. Workplace related injury data from 1992 to 2018 was collected from the Bureau of Labor Statistics “Workplace Injuries & Illnesses” database. Occurrence of trunk, upper-extremity, and lower-extremity injuries in major industries (agriculture, construction, manufacturing, and healthcare) were aggregated during this time period and compared. Overall workplace related injury occurrence in major industries …
