Static V. Expandable Tlif Cage Outcomes, Harrison Pajovich, Ryan Nachwalter, Lohit Velagapudi, Joseph Zarowin, Alexander R. Vaccaro, Md, Phd
Static cages were introduced in the 1990s as a solution to degenerative spondylolisthesis, recurrent disc herniation and spinal stenosis. As this procedure was popularized, a new class of expandable Transforaminal Lumbar Interbody Fusion devices was introduced to further improve outcomes that will be studied in this project. It will be explored how expandable cages compare to static cages in TLIF procedures in patient-reported outcomes, complications and restoration of appropriate lumbar lordosis. We conducted a retrospective cohort review comparing those who received expandable and static cages. Eligible patients received TLIF procedure at the Rothman Institute, were ≥18 years of age and ...
Neoangiogenesis And Blood-Brain Barrier Dysfunction In Human Tsc Brain Lesions, 2020 Thomas Jefferson University
Neoangiogenesis And Blood-Brain Barrier Dysfunction In Human Tsc Brain Lesions, Kimberly Sansalone, Pelin Dilsiz, Howard Weiner, Orrin Devinsky, Delia M. Talos
Introduction: Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the presence of multiple benign tumors throughout the body and brain. Patients with TSC experience severe cognitive dysfunction and therapy-resistant seizures, which can be associated with refractory epilepsy and poor developmental outcomes. We hypothesize that neoangiogenesis, disruption of the blood-brain barrier, and leakage of serum proteins into the brain parenchyma play vital roles in the pathogenesis of TSC.
Methods: In order to assess blood-brain barrier integrity, cortical tissue samples from TSC patients with intractable seizures, non-TSC patients with therapy-resistant epilepsy, and control subjects were immunolabeled for the serum protein ...

Development Of A Hert Trained Interprofessional Student Decontamination Team For Hospital Mass Casualty Response, Ashley Wong, Claire Zurlo, Edward Jasper
Introduction: FEMA’s Hospital Emergency Response Training (HERT) prepares healthcare workers to decontaminate patients during a mass casualty incident. This depletes the emergency department (ED) staff when they are needed most though. Developing an interprofessional student composed HERT team to screen and decontaminate affected populations will allow ED staff to handle more medically complex situations during a mass casualty event.
Methods: Likert scale surveys were conducted among ED physicians and nurses at Jefferson Hospital and HERT trained medical and nursing students at Jefferson University. These were to evaluate the training program and ED staff opinions of utilizing a student HERT ...
Development Of Vaccine Preferences In Parents Of Newborns, 2020 Thomas Jefferson University
Development Of Vaccine Preferences In Parents Of Newborns, Ramon Ruiz, Neera Goyal
Introduction: The resurgence in cases of vaccine-preventable childhood diseases in the U.S. may be associated with increasing rates of vaccine hesitancy. Although previous research has sought to identify attributes of non-vaccinating parents, the timing in which parents make such vaccination decisions has yet to be explored. Our goal is to identify when first-time parents develop their vaccination preferences: before, after, or during pregnancy.
Methods: A cross sectional survey was conducted using a convenience sample of 73 first time parents at Thomas Jefferson University Hospital. Survey questions addressed timing of vaccination decisions and projected compliance with vaccine schedules. Eligibility for ...

Outcomes In Knot Vs Knotless Surgery In Labrum Tears, 2020 Thomas Jefferson University
Outcomes In Knot Vs Knotless Surgery In Labrum Tears, Zachary Howell, Benjamin Hendy, Md
A Bankart lesion is a tear of the anterior and inferior glenoid labrum. The primary method of repairing this lesion is to sew the detached part back to the joint, however there is a relatively newer method of doing so that does not involve tying a knot in the joint which may cause less joint irritation. The question our research project attempted to answer was: How do the long-term outcomes associated with knotless Bankart labrum repairs compare with the knot repairs? A retrospective cohort study was done with Rothman Institute Bankart lesion patients from 2010-2016. Data was gathered over phone ...

Lee, Md
Introduction: Intervertebral distraction in anterior cervical discectomy and fusion (ACDF) has been postulated to injure the degenerative facet joints posteriorly and increase postoperative pain and disability. This study aims to determine if there is a correlation between the amount of facet distraction and postoperative patient reported outcomes.
Methods: A retrospective cohort analysis of patients undergoing ACDF for degenerative pathologies was performed. Each patient received lateral cervical spine x-rays at the immediate postoperative time point and were split into groups based on the amount of facet distraction measured on these films: Group A: < 1.5 mm; Group B: 1.5-2.0 mm; and Group C: > 2.0 mm. Patients reported outcome measures were ...
Identifying The Prevalence Of Underdiagnosed Obstructive Sleep Apnea (Osa) In The Primary Care Population Via Targeted Screening Measures, Risa Goldberg, Alyssa Givens, Cynthia Cheng, Md, Phd
Introduction: Obstructive sleep apnea (OSA) is a condition with detrimental health consequences, yet over 75% of OSA cases remain undiagnosed in the United States. This study aimed to determine the efficacy of using targeted screening measures to determine the prevalence of undiagnosed OSA in a primary care population.
Methods: This prospective pilot study utilized a primary care population from Thomas Jefferson University’s family medicine department. Participants were selected using three risk criteria for OSA from STOP-BANG identifiable from their EMR records (BMI >35, age over 50, and hypertension). After screening out patients previously diagnosed with OSA, patients were called ...
Conversion Total Knee Arthroplasty Needs Its Own Diagnosis Related Group Facility Reimbursement Code, 2020 Thomas Jefferson University
Conversion Total Knee Arthroplasty Needs Its Own Diagnosis Related Group Facility Reimbursement Code, Jonah Stein, Michael Yayac, Md, Gregory K. Deirmengian, Md, Javad Parvizi, Md, P. Maxwell Courtney, Md
Introduction: Conversion from a prior surgery to a total knee arthroplasty (TKA) is a more technically difficult procedure than primary TKA and is associated with worse short-term outcomes and increased complication and readmission rates, despite being undifferentiated under the current bundled payment model. The aim of this study was to determine differences in facility costs between primary TKA and conversion TKA, which we hypothesize are significant, to ensure providers are not penalized for treatment and high-risk patients have the same access to care.
Methods: We retrospectively reviewed a consecutive series of patients undergoing primary TKA at two hospitals within Rothman ...
The Effect Of Perceived Physician Opinion On Breastfeeding In Women With Opioid Use Disorder Who Are Receiving Medication-Assisted Treatment, Lacey Murray, Meghan Gannon, Phd, Vanessa Short, Phd, Mph
Women who receive medication-assisted treatment (MAT) for opioid use disorder (OUD) are less likely to breastfeed than the general population despite the many possible benefits to the newborn. The ongoing study examines the effect of perceived physician opinion on the outcome of breastfeeding in women receiving MAT for OUD. Women who were receiving MAT for OUD at Thomas Jefferson University’s Family Center were given a survey during their third trimester (n=45), and at 1 month postpartum (n=33) to gather information on the perceived opinion of their physicians on how they should feed their baby and the importance ...
Hepatocellular Carcinoma Treated With Microwave Ablation Prior To Liver Transplantation, 2020 Thomas Jefferson University
Hepatocellular Carcinoma Treated With Microwave Ablation Prior To Liver Transplantation, Nicole Wagner, Amanda Smolock, Michael Markovitz, Varun Danda, Christopher Neely, Warren Maley, Jesse Civan, Colette Shaw
Introduction: Ablation is a minimally invasive procedure that limits local liver tumor progression and prolongs patients’ transplantation eligibility. Microwave ablation (MWA) utilizes higher temperatures than the standard of care, radiofrequency ablation (RFA), which increases efficiency. Meta-analyses compared MWA with RFA for the treatment of HCC and showed similar efficacy and safety between these modalities. However, limited pathologic data exists determining whether explanted tumors remained viable after MWA.
Methods: Our database was reviewed retrospectively for patients with HCC who underwent MWA prior to liver transplantation between 2013 and 2019. Patient demographics, etiology of disease, tumor size, procedure details, bilirubin, MELD, and ...

Treatment Of Persistent Air Leaks Using Endobronchial Valves, Michael Zimmerman, Cole Zingas, Achala Donuru, Scott W. Cowan, Nathaniel Evans Iii, Boyd Hehn
Introduction: Persistent air leaks (PAL) are from bronchopleural fistula resulting from communication between the bronchial tree and pleural space. Endobronchial valves (EBVs) are unidirectional valves placed bronchoscopically preventing airflow to the diseased lung lobe. For non-operable patients with PALs, EBVs offer a potential non-invasive treatment approach to stop air leak and allow lung healing. The purpose of this study is to retrospectively analyze EBV placement to treat non-operable adult patients with PALs.
Methods: We retrospectively analyzed all adult patients that underwent EBV placement for PAL treatment at our institution from January 2016 to June 2019. All patients failed conservative therapy ...
