Phase 1

Introduction: Primary central nervous system lymphoma (PCNSL) is a rare entity typically treated with a combination of chemotherapy and radiation. The role of surgery is controversial, and biopsy may be non-definitive or injurious. We review our series of stereotactic and excisional biopsy as well as surgical debulking of PCNSL to quantify overall risk and benefits.

Methods: Patients with biopsy-confirmed intracranial PCNSL were identified from a large singlecenter academic institution between 2012-2018. Preoperative factors and perioperative outcomes were retrospectively reviewed.

Results: A total of 61 cases of PCNSL were identified. Most patients presented with confusion (23.0%), weakness/paralysis (19.7%), and gait disturbance …

Effects Of Medications On Cognitive Function And Falls In Older African Americans With Diabetes, Diana Alnemri, Robin J. Casten

Phase 1

Introduction: Potentially-inappropriate medications (PIMs) are medications that have increased rates of adverse drug events in older adults. Medications with anticholinergic activity are classified as PIMs since they can lead to cognitive dysfunction and increased fall risk. PIM use is higher among African Americans (AA) than Whites.

Methods: This study explored relationships among cognitive function, falls, and PIMs in AAs with diabetes. This study recruited AAs with diabetes (n=99, age ≥60yrs) who were seen in the Emergency Department (ED), and were enrolled in a trial of a behavioral intervention to improve diabetes management. PIMs were based on the Beer’s criteria …

Outcomes In Knot Vs Knotless Surgery In Labrum Tears, Zachary Howell, Benjamin Hendy, Md

Phase 1

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 …

Phase 1

Background: Current awareness around childhood vaccinations and associated requirements for school entry has been heightened both nationally and internationally as governments work to find a balance between protecting their residents’ health and personal freedoms. Scant research exists examining the characteristics of these vaccine exemptors, but as the percentage of students seeking these exemptions increases yearly, this yields an opportunity to identify trends and inform future policy.

Question: What are the associations between reason for exemption from mandated vaccinations and the demographics of race and gender for school-aged children in the state of Delaware?

Results: Drawing from school nurse vaccine exemption …

Using Electrolyte Repletion Guidelines To Improve The Rate Of Oral Potassium And Magnesium Delivery, Joshua Riley, Alan Kubey, Md

Phase 1

Introduction: Evidence-based guidelines for electrolyte replacement that safely encourage oral (PO) and/or intravenous (IV) dosing more successfully attain goal levels than standard care. However, the Thomas Jefferson University Hospital (TJUH) electrolyte replacement guidelines (JG 11-1296), approved in 2002 and last updated in 2008, provide guidance for IV repletion not PO. Between 5/2017-11/2017, TJUH dosed potassium and magnesium in a 2.30 and 4.24 IV:PO ratio, respectively. If 50% of doses were given PO, we anticipate ~$800,000 annual TJUH savings.

Methods: We created a multidisciplinary team and completed a literature review to inform the creation of updated TJUH guidelines for …

The Role Of Different Tv Storytelling Approaches In Engaging U.S. Hispanic Parents And Caregivers Around Early Childhood Development, Caty Borum Chattoo, Lauren Feldman, Amy Henderson Riley

College of Population Health Faculty Papers

Educational achievement gaps exist between racial and ethnic groups in the United States; early childhood readiness, fostered in part by parents and caregivers, is crucial. To respond to this challenge, the Univision television network produced content that aired across 3 storytelling genres (scripted drama, reality, news) to entertain and educate Hispanic parents and primary caregivers of children ages 0–5 years about early brain development interventions. This pretest/posttest experimental study assessed the impact of each genre and found significant direct effects on knowledge, attitudes, and behavioral intentions; the effects were mediated by perceived entertainment value and positive emotions.

A Crucial Role For The Protein Quality Control System In Motor Neuron Diseases., Riccardo Cristofani, Valeria Crippa, Maria Elena Cicardi, Barbara Tedesco, Veronica Ferrari, Marta Chierichetti, Elena Casarotto, Margherita Piccolella, Elio Messi, Mariarita Galbiati, Paola Rusmini, Angelo Poletti

Department of Neuroscience Faculty Papers

Motor neuron diseases (MNDs) are fatal diseases characterized by loss of motor neurons in the brain cortex, in the bulbar region, and/or in the anterior horns of the spinal cord. While generally sporadic, inherited forms linked to mutant genes encoding altered RNA/protein products have also been described. Several different mechanisms have been found altered or dysfunctional in MNDs, like the protein quality control (PQC) system. In this review, we will discuss how the PQC system is affected in two MNDs-spinal and bulbar muscular atrophy (SBMA) and amyotrophic lateral sclerosis (ALS)-and how this affects the clearance of aberrantly folded proteins, which …

Quetiapine And Wolff-Parkinson-White Syndrome, Michael Chen, Hassaan Gomaa, Alonso Cortez-Resendiz, Christopher Martin, Andrew Francis, Alfredo Bellon

Department of Psychiatry and Human Behavior Faculty Papers

Quetiapine is occasionally associated with cardiovascular adverse effects such as QTc prolongation. QTc prolongation is a side effect that requires monitoring in order to avoid more serious cardiac complications. One particular understudied area is the potential for antipsychotics to elicit electroconduction abnormalities in patients with Wolff-Parkinson-White (WPW) Syndrome. In the present report, we describe a case of quetiapine overdose in a patient with WPW.

Department of Neurosurgery Faculty Papers

While medical and technological advances continue to shape and advance health care, there has been growing emphasis on translating these advances into improvement in overall health care quality outcomes in the United States. Innovators such as Abraham Flexner and Ernest Codman engaged in rigorous reviews of systems and patient outcomes igniting wider spread interest in quality improvement in health care. Codman's efforts even contributed to the founding of the American College of Surgeons. This society catalyzed a quality improvement initiative across the United States and the formation of the Joint Commission on Accreditation of Hospitals. Since that time, those such …

Early Surgery For Traumatic Spinal Cord Injury: Where Are We Now?, Jefferson R. Wilson, Christopher D. Witiw, Jetan Badhiwala, Brian K. Kwon, Michael G. Fehlings, James Harrop

Department of Neurosurgery Faculty Papers

Study Design: Narrative review.

Objective: There is a strong biological rationale to perform early decompression after traumatic spinal cord injury (SCI). With an enlarging clinical evidence base, most spine surgeons internationally now favor early decompression for the majority of SCI patients; however, a number of pertinent questions remain surrounding this therapy.

Methods: A narrative review evaluating the status of early surgery for SCI. In particular, we addressed the following questions: (1) Which patients stand to benefit most from early surgery? 2) What is the most appropriate time threshold defining early surgery?

Results: Although heterogeneity exists, the evidence generally seems to …

Department of Medical Oncology Faculty Papers

In late January 2020, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2) was reported as an outbreak in Wuhan, China. Within 2 months it became a global pandemic. Patients with cancer are at highest risk for both contracting and suffering complications of its resultant disease, Coronavirus 19 (COVID-19). Healthcare systems across the world had to adapt quickly to mitigate this risk, while continuing to provide potentially lifesaving treatment to patients. Bringing care to the home through the use of telehealth, home based chemotherapy, and remote patient monitoring technologies can help minimize risk to the patient and healthcare workers without sacrificing quality …

Management Of Patients With Hematologic Malignancies During The Covid-19 Pandemic: Practical Considerations And Lessons To Be Learned, Alessandro Isidori, Laurence De Leval, Usama Gergis, Pellegrino Musto, Pierluigi Porcu

Department of Medical Oncology Faculty Papers

The COVID-19 pandemic has created unprecedented hurdles to the delivery of care to patients with cancer. Patients with hematologic malignancies appear to have a greater risk of SARS-CoV-2 infection and severe disease due to myelosuppression and lymphopenia. The first challenge, therefore, is how to continue to deliver effective, curative therapy to vulnerable patients and at the same time avoid exposing them, and their health care teams (HCT), to SARS-CoV-2. An additional challenge is the timely completion of the diagnostic and staging studies required to formulate appropriate treatment plans. Deferred procedures and avoidance of multiple trips to the surgical, diagnostic, and …

Potential Roles Of Extracellular Vesicles In The Pathophysiology, Diagnosis, And Treatment Of Autoimmune Diseases., Jing Tian, Giacomo Casella, Yuan Zhang, Abdolmohamad Rostami, Xing Li

Department of Neurology Faculty Papers

Since extracellular vesicles (EVs) were discovered in 1983 in sheep reticulocytes samples, they have gradually attracted scientific attention and become a topic of great interest in the life sciences field. EVs are small membrane particles, released by virtually every cell that carries a variety of functional molecules. Their main function is to deliver messages to the surrounding area in both physiological and pathological conditions. Initially, they were thought to be either cell debris, signs of cell death, or unspecific structures. However, accumulating evidence support a theory that EVs are a universal mechanism of communication. Thanks to their biological characteristics and …

Investigating The Effects Of Brainstem Neuronal Adaptation On Cardiovascular Homeostasis., James H Park, Jonathan Gorky, Babatunde Ogunnaike, Rajanikanth Vadigepalli, James S Schwaber

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Central coordination of cardiovascular function is accomplished, in part, by the baroreceptor reflex, a multi-input multi-output physiological control system that regulates the activity of the parasympathetic and sympathetic nervous systems via interactions among multiple brainstem nuclei. Recent single-cell analyses within the brain revealed that individual neurons within and across brain nuclei exhibit distinct transcriptional states contributing to neuronal function. Such transcriptional heterogeneity complicates the task of understanding how neurons within and across brain nuclei organize and function to process multiple inputs and coordinate cardiovascular functions within the larger context of the baroreceptor reflex. However, prior analysis of brainstem neurons revealed …
