Investigation Of The Reciprocal Relationship Between C7, Tsp1, And Tgf-Β Activation In Normal Fibroblasts, Alicia Kenyon, Andrew South, Phd

Phase 1

Introduction: Recessive dystrophic epidermolysis bullosa (RDEB) is a rare skin blistering disorder due to a loss of function mutation in the collagen 7 (C7) gene. C7 activity loss upregulates thrombospondin-1 (TSP1), stimulating tissue growth factor-ß (TGF-ß), which promotes the development of cutaneous squamous cell carcinoma (cSCC) in RDEB patients. This C7-TSP1 interaction has not been described in normal fibroblasts; therefore, in this study, we tested the hypothesis that the level of intracellular C7 negatively correlates with TSP1 expression in normal fibroblasts.

Methods: In this basic research cell study, C7, TSP1, and pSMAD3 (phosphorylated SMAD3), a marker of TGF-ß activation, were …

Phase 1

Introduction: Fistula formation between the trachea and the innominate artery is a life-threatening complication rarely seen with existing or previous tracheostomy. Fatal upon rupture, swift diagnosis and immediate intervention are paramount for survival. We aim to identify feasibility and outcomes of endovascular intervention for trachea-innominate fistula (TIF).

Methods: Patient-level data of reported individuals above the age of 14 that underwent endovascular intervention for TIF was extracted and analyzed. Identification of 25 patients from 27 studies was accomplished by electronic database search of Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Ovid Medline, …

Effects Of Continuous Positive Airway Pressure On Blood Pressure In Obstructive Sleep Apnea, Amy He, Dani Yellanki, Grace Severance, Peter Zhang, Zachary Feuer, Natali Salinas, Cynthia Cheng, Md, Phd

Phase 1

Introduction:

Obstructive sleep apnea (OSA) has been previously linked to the development of hypertension, possibly through the proposed mechanism of recurrent episodes of intermittent hypoxia leading to endothelial dysfunction, inflammation, and metabolic dysregulation. This study aims to investigate continuous positive airway pressure (CPAP) therapy, a first-line therapy for OSA, and its effects on blood pressure in patients with moderate to severe OSA. We hypothesize that compliance to CPAP leads to a decrease in average annual systolic and diastolic blood pressure, compared to noncompliant and non-CPAP use.

Methods:

Our study is a combined retrospective and prospective EPIC chart review study. Moderate …

Cardiac Arrest Clinical Outcomes In Patients Presenting With Opioid Overdose, Andrew Toron, Morgan Hutchinson, Md, David Gaieski

Phase 1

Introduction: Understanding opioids and their potential to cause cardiac arrests is integral in learning how to lower mortality rates in patients who overdose on them. Few studies have specifically examined the association of out-of-hospital cardiac arrests with opioid overdoses. We hypothesized that cardiac arrests caused by opioid overdoses will result in longer hospital stays and a higher mortality rate than other cardiac arrests.

Methods: This study is a secondary analysis of data from the Cardiac Arrest Registry to Enhance Survival. Data regarding 35 patients who presented to Jefferson and Methodist hospitals with out-of-hospital cardiac arrests due to opioid overdose …

Deep Supratentorial Extension Is Associated With Poor Clinical Outcomes After Glioblastoma Resection, Adam Barsouk, Michael P. Baldassari, Omaditya Khanna, Donald Ye, Erica Cunningham, Christopher Farrell, David Andrews, James Evans, Kevin Judy

Phase 1

Introduction: Glioblastoma (GBM) often extends to deep supratentorial locations, which limits the extent of maximal safe resection. Deep supratentorial extension (DSE) may be a clinically convenient prognostic indicator following GBM resection.

Methods: 582 GBM resections from 2012-2018 were retrospectively reviewed. DSE was defined as tumoral extension to the basal ganglia, thalamus, corpus callosum, internal capsule, hypothalamus, caudate, or putamen as identified on preoperative imaging.

Results: DSE was identified in 32.9% cases (192), while 52.5% (306) involved only superficial supratentorial locations (frontal, parietal, temporal and occipital lobes). Within the DSE cohort, the most commonly affected anatomical locations were the corpus …

Angiogram Negative Subarachnoid Hemorrhage: Incidence, Outcomes, And Predisposition, Victoria Coaxum, Ahmad Sweid, Md, Julie Barbera, Nicolas Nelson, Grace Severance, Angelo D'Antonio-Bertagnolli, Manan Parekh

Phase 1

Introduction: Subarachnoid hemorrhage (SAH) is a medical emergency that may lead to deleterious outcomes unless the underlying cause is determined and managed promptly to prevent further rebleed. Though a significant percentage of cases of SAH have no identifiable pathology, there is a lack of data related to outcomes, predispositions, and whether there has been an increase in the incidence of angiogram negative SAH (anSAH). This study aimed to assess the current incidence of anSAH and factors that are associated with outcomes and predisposition among patients diagnosed with anSAH.

Methods: A retrospective chart review was performed. Medical records of patients …

Procedural And Clinical Outcomes Of Transitioning To High Power Short Duration Guided Ablation For Atrial Fibrillation, Zachary Pang, Sean J. Dikdan, Joey Junarta, Sairamya Bodempudi, Naman Upadhyay, Md, Daniel R. Frisch

Phase 1

Introduction: High-power short-duration (HPSD; 50W for up to 15s) ablation is a novel way to use a contact force-sensing catheter optimized for power-controlled radiofrequency ablation of atrial fibrillation (AF). Our goal was to compare the procedural and clinical outcomes of AF ablation with HPSD to previous ablation methods used, including standard-power standard duration (SPSD; 20-25W, up to 60s) and temperature-controlled non-contact (TCNC; 20-40W, up to 60s).

Methods: Procedural and clinical data was from consecutive cases of patients with paroxysmal or persistent AF undergoing pulmonary vein isolation with HPSD, TCNC and SPSD between 7/1/13 to 11/1/19. A total of 171 patients …

Krampitz, Wilbur Bowne, Hamza Rshaidat, Cyrus J. Sholevar, Alexandra C. Leto, William Preston, Elwin Tham, Mandeep Shergill, Shawnna Cannaday, Theresa Yeo, Harish Lavu, Charles J. Yeo

Phase 1

Introduction:

Pancreaticoduodenectomy (PD) is a complex abdominal procedure with high rates of perioperative morbidity. The Whipple Accelerated Recovery Pathway (WARP) was developed for highly selected patients undergoing PD to reduce hospital length of stay (LOS) and time to adjuvant therapy (TTAT), without increasing post-operative complications (POC) or readmission rates (RR). The purpose of this study was to determine if WARP could be implemented for all-risk patients undergoing PD.

Methods:

A single-institution, retrospective analysis of 281 patients implemented on the WARP between 2017-2020 was performed. 119 patients were categorized as WARP-eligible (WEPs) according to original inclusion criteria, and 162 were …

Efficacy Of An Appointment Specialist In Reducing Loss To Follow Up In A Retina Practice, Turner D. Wibbelsman, Michael Ammar, Md, Anthony Obeid, Md, Mph, Jason Hsu, Md

Phase 1

Introduction:

Although a new armamentarium has greatly benefitted patients with retinal disease, novel therapeutic approaches require more frequent clinic visits, which may lead to missed treatments and vision loss. This study characterizes patient-reported reasons for missed visits and assesses the efficacy of calling patients for rescheduling missed visits.

Methods:

This retrospective cohort study included patients who missed an appointment for an intravitreal injection between January 2018 and February 2020 at the Retina Service of Wills Eye Hospital. Two calls were made to each patient by an appointment specialist to reschedule the visit and record a reason for the …

Anatomic Location And Mortality Of Pancreatic Adenocarcinoma: A Single Institution Study, Sophia Lam, Randi Zukas, Ida Micaily, Atrayee Basu Mallick

Phase 1

In pancreatic adenocarcinoma, it is believed that patients with proximal tumors (head) have earlier diagnosis and higher survival due to anatomic location compared to patients with distal tumors (body/tail). We hypothesized that differences in tumor biology would contribute to poorer survival in body/tail tumors compared to head tumors when diagnosed at the same stage.

We performed a retrospective chart review on 324 patients with pancreatic adenocarcinoma (236 head and 88 body/tail) diagnosed from 2011-2017. We gathered electronic health records from a single center with a high volume of pancreatic cancer directed surgery. We compared median patient survival from onset of …

Factors Influencing Efficacy And Satisfaction In Prenatal Counseling For Families With Single Ventricle Heart Disease, Taylor Hartzel Houlihan, Jack Rychik, Md

Phase 1

Introduction: The Fetal Heart Program at Children’s Hospital of Philadelphia offers prenatal counseling to families with congenital heart disease diagnoses. This center has yet to examine family satisfaction with counseling, especially those with complicated single ventricle diagnoses. While families may receive sufficient education about their child’s condition, better communication may be needed to prepare them for potential neurological and behavioral complications.

Methods: Through chart review, 355 patient families with single ventricle diagnoses who utilized CHOP prenatal counseling within the past 10 years were identified. Retrospective surveys including Likert scales and open-ended questions were distributed by email. 65 responses were …

Treatment Of Distal Radius Fractures In Patients Over 80 Years Of Age: Functional Outcomes After Open Reduction And Internal Fixation Versus Nonoperative Treatment, Robert Gallivan, Lili E. Schindelar, Md, Mph, Richard Mcentee, Pedro K. Beredjiklian, Md

Phase 1

INTRODUCTION

Distal radius fractures are one of the most common fractures seen in the elderly. With the younger physiological age of patients over 60 years, the expectation of functional outcomes is changing. The management of distal radius fractures in the elderly patient, especially those over the age of 80, has not been well defined. The purpose of this study was to compare operative to nonoperative treatment of distal radius fractures in patients older than 80 years to determine if there is any difference in functional outcomes or complications.

METHODS

A retrospective review was performed to identify patients 80 years or …

Coronary Artery Disease And Nonalcoholic Fatty Liver Disease: Clinical Correlation Using Ct Coronary Calcium Scans, Richard S. Kirby, Dina Halegoua-De Marzio

Phase 1

Introduction: Nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) have been explored with coronary angiography which showed a link between severe NAFLD and CVD risk. This study’s aim is to determine if CT coronary artery calcium (CAC) scores used to determine CAD severity in asymptomatic populations can help predict presence of NAFLD.

Methods: Retrospective cross-sectional study of positive CT CAC scores and liver imaging with either CT, ultrasound, or MRI of the abdomen or CT of the chest. Drinking 7 or 14 drinks per week for a woman or man respectively and chronic viral hepatitis diagnosis …

Abcd Progression Post Crosslinking For Keratoconus, Sonali Patel, Neil Vadhar, Zeba Syed

Phase 1

Introduction:

Keratoconus is a corneal disease that leads to various ocular illnesses such as scarring and thinning and the most common treatment for this disease at this time is Cross Linking. Previously, post-surgical outcomes of cross linking were analyzed using the AK (Amsler- Krumeich) system which didn’t account for posterior corneal surface and corneal thickness. In order to overcome these shortcomings, a new ABCD classification was developed which accounts for anterior (A) and posterior (B) radius of curvature, thinnest corneal pachymetry (C) and distance for best corrected vision (D).

Methods:

A retrospective study was done using 104 patients who …

Does Prior Acromioplasty Increase The Incidence Of Acromial Fracture Following Reverse Total Shoulder Arthroplasty? A Retrospective Matched Cohort Analysis, Olivia Blaber, Brandon J. Erickson, Md, Christopher Hadley

Phase 1

Introduction: Reverse total shoulder arthroplasty (RTSA) is an effective treatment option for multiple shoulder pathologies. Arthroscopic acromioplasty is a treatment for subacromial impingement. RTSA can place excess stress on the acromion. No studies have evaluated outcomes following RTSA among patients with prior acromioplasty. The purpose of this study was to report outcomes in patients following RTSA who have had a prior acromioplasty. The authors hypothesized patients with prior acromioplasty who undergo RTSA will have significant improvements in clinical outcomes with no increased risk of acromial fracture.

Methods: Patients from a single institution who underwent RTSA with a history of acromioplasty …

Assessment Of Treatment Response Of Keloid Patients, Rachel Zachian, Mary Metkus, John Bruckbauer, Neda Nikbakht

Phase 1

Introduction: Keloids are benign exophytic scars ranging from asymptomatic, small papules to large symptomatic plaques that affect patients’ quality of life. The most effective treatment for this troublesome condition has yet to be determined. This study aims to demonstrate that intralesional Kenalog injections produce better keloid outcomes than surgical excision.

Methods: Researchers called 504 Jefferson keloid patients to determine their keloid outcomes post-treatment. Patients were asked to confirm their last treatment method, describe the percent change in size of their lesion(s), and rate their symptoms (pruritis and pain) on a scale of 0-10 before and after treatment. Excision and …

High grade injuries may require operative fixation, and comprehensive return to play guidelines have not yet been established. The purpose of this investigation is to summarize return to play criteria following operative management of AC joint separation.

Methods: A systematic review of the literature was performed to evaluate clinical evidence regarding return to play following operative management of isolated AC joint separation. Studies satisfying inclusion criteria were analyzed for return to play timeline and other factors used to guide return to play following surgery.

Results: Sixty-three …

Real-Time Baseline Coagulation Profiles Using Rotem In Patients Undergoing Liver Transplantation, Paul Del Prato, Uzung Yoon, Md

Phase 1

Real-time monitoring of blood coagulation during invasive surgeries is an important component of ensuring patient safety and effective treatment. Rotational thromboelastometry (ROTEM) is a viscoelastic monitoring system of hemostasis in blood that allows for ongoing measurement of global markers of coagulation. This study compares coagulation in a population of hepatocellular carcinoma liver-transplant patients (HCC) with a transplant population of other etiologies (non-HCC). A database of ROTEM measurements acquired peri-operatively during liver transplantation was compiled from over 400 Jefferson patients. A baseline profile was developed comprised of ROTEM measurements of clot initiation/stability that can be used as a methodological standard. Analysis …

Assessment Of Hyperfibrinolysis In Liver Transplantation Surgery As Measured By Rotational Thromboelastometry, Ryan Madsen, Uzung Yoon, Marc Torjman

Phase 1

Hyperfibrinolysis is a significant concern during liver transplantation surgeries. Rotational thromboelastometry (ROTEM) is a point of care device that is capable of intraoperatively measuring the clotting properties of whole blood samples, including the rate of fibrinolysis. The aim of this study was to use ROTEM to determine if improved surgical techniques have lowered rates of hyperfibrinolysis during liver transplantations. Blood samples were taken from 284 patients during liver transplantations that took place over five years from 2014-2019. The blood samples were drawn at various time points during the preanhepatic phase, anhepatic phase, and neohepatic phase of the surgery. Hyperfibrinolysis was …
