Angioimmunoblastic T-cell lymphoma (AITL) is one of four major subtypes of nodal peripheral T cell lymphoma, characterized by its cell of origin, the follicular helper T-cell (TFH). Patients typically present with prominent constitutional (B) symptoms, generalized lymphadenopathy, hepatosplenomegaly, cytopenias, and rash. Here we present a case of a 62-year-old male with progressive cervical adenopathy, fevers and weight loss presenting with extreme polyclonal plasmacytosis and high plasma EBV viral load. While the initial presentation appeared to mimic plasma cell leukemia or severe infection, lymph node biopsy and bone marrow biopsy confirmed a diagnosis of AITL. This case highlights the heterogeneity of …

Introduction: Adolescence is a time of significant physical and emotional change, and there is emerging concern that adolescents living in low- and middle-income countries (LMIC) may face substantial challenges in relation to linear growth and mental health. Data on the global burden of stunting after 5 years of age are limited, but estimates suggest up to 50 per cent of all adolescents in some LMIC are stunted. Additionally, many LMIC lack robust mental health care delivery systems. Pakistan has one of the world's largest populations of adolescents (10 to 19 years) at approximately 40 million. The Nash-wo-Numa study's primary objective …

Background: Acute kidney injury after cardiac surgery significantly associates with morbidity and mortality. Despite not requiring cardiopulmonary bypass, transcatheter aortic valve replacement patients have an incidence of post-procedural acute kidney injury similar to patients who undergo open surgical aortic valve replacement. Packed red blood cell transfusion has been associated with morbidity and mortality after cardiac surgery. We hypothesized that packed red blood cell transfusion independently associates with acute kidney injury after transcatheter aortic valve replacement, after accounting for other risk factors.
Methods: This is a single-center retrospective cohort study of 116 patients undergoing transcatheter aortic valve replacement. Post-transcatheter aortic valve …

Articles, Abstracts, and Reports
Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic condition most commonly characterized by hypertrophy of the ventricular septum, which leads to left ventricle outflow obstruction. Due to the severity of the condition, it is often diagnosed in adolescents, especially in those who exercise. We describe the case of a 53-year-old male, previously undiagnosed with hypertrophic cardiomyopathy (HCM), who became dyspneic during a bike race. He was found to have elevated troponin, pulmonary edema, and was diagnosed with HOCM. The late presentation of the case, in an active individual, makes the situation unique.

BACKGROUND: Biochemical marker has revolutionized the approach to the diagnosis of heart failure. However, it remains difficult to assess stability of the patient. As such, novel means of stratifying disease severity are needed. C1q/TNF-Related Protein 3 (CTRP3) and C1q/TNF-Related Protein 9 (CTRP9) are novel adipokines that contribute to energy homeostasis with additional anti-inflammatory and anti-ischemic properties. The aim of our study is to evaluate concentrations of CTRP3 and CTRP9 in patients with HFrEF (heart failure with reduced ejection fraction) and whether associated with mortality.
METHODS: Clinical data and plasma were obtained from 176 healthy controls and 168 patients with HFrEF. …

While GM1 may interact with α-synuclein in vitro to inhibit aggregation, the ability of GM1 to protect against α-synuclein toxicity in vivo has not been investigated. We used targeted adeno-associated viral vector (AAV) overexpression of human mutant α-synuclein (A53T) in the rat substantia nigra (SN) to produce degeneration of SN dopamine neurons, loss of striatal dopamine levels, and behavioral impairment. Some animals received daily GM1 ganglioside administration for 6 weeks, beginning 24 hours after AAV-A53T administration or delayed start GM1 administration for 5 weeks beginning 3 weeks after AAV-A53T administration. Both types of GM1 administration protected against loss of SN …

BACKGROUND: Increased tendon pain and tendon damage is a significant complication related to hyperlipidemia. Unlike the well-established pathogenesis associated with increased serum concentrations of total cholesterol, triglycerides, and low-density lipoprotein in atherosclerotic cardiovascular disease, the role of hyperlipidemia in promoting tendon damage remains controversial and requires mechanistic clarity.
METHODS: In this study, we analyzed the consequences of hypercholesterolemia on the integrity of the collagen-based architecture of the Achilles tendon. The Achilles tendons from rabbits fed with normal-cholesterol (nCH) and high-cholesterol (hCH) diets were analyzed. We studied the morphology of tendons, distribution of lipids within their collagen-rich milieu, the relative amounts …

An Integration-To-Bound Model Of Decision-Making That Accounts For The Spectral Properties Of Neural Data, Ramón Guevara Erra, Marco Arbotto, Aaron Schurger
Psychology Faculty Articles and Research
Integration-to-bound models are among the most widely used models of perceptual decision-making due to their simplicity and power in accounting for behavioral and neurophysiological data. They involve temporal integration over an input signal (“evidence”) plus Gaussian white noise. However, brain data shows that noise in the brain is long-term correlated, with a spectral density of the form 1/fα (with typically 1 < α < 2), also known as pink noise or ‘1/f’ noise. Surprisingly, the adequacy of the spectral properties of drift-diffusion models to electrophysiological data has received little attention in the literature. Here we propose a model of accumulation of evidence for decision-making that takes into consideration the spectral properties of brain signals. We develop a generalization of the leaky stochastic accumulator model using a Langevin equation whose non-linear noise term allows for varying levels of autocorrelation in the time course of the decision variable. We derive this equation directly from magnetoencephalographic data recorded while subjects performed a spontaneous movement initiation task. We then propose a nonlinear model of accumulation of evidence that accounts for the ‘1/f’ spectral properties of brain signals, and the observed variability in the power spectral properties of brain signals. Furthermore, our model outperforms the standard drift-diffusion model at approximating the empirical waiting time distribution.

Interprofessional education (IPE) typically involves clinical simulation exercises with students from medical and nursing schools. Yet, healthcare requires patient-centered teams that include diverse disciplines. Students from public health and informatics are rarely incorporated into IPE, signaling a gap in current educational practices. In this study, we integrated students from administrative and non-clinical disciplines into traditional clinical simulations and measured the effect on communication and teamwork. From July 2017-July 2018, 408 students from five schools (medicine, nursing, dentistry, public health, and informatics) participated in one of eight three-hour IPE clinical simulations with Standardized Patients and electronic health record technologies. Data were …

Cholesterol is a pivotal factor for cancer cells to entertain their relentless growth. In this case, we provide a novel strategy to inhibit tumor growth by simultaneous activation of liver-X-receptors and interference with Tumor Necrosis Factor Receptor-associated Protein 1 (TRAP1). Informed by a transcriptomic and subsequent gene set enrichment analysis, we demonstrate that inhibition of TRAP1 results in suppression of the cholesterol synthesis pathway in stem-like and established glioblastoma (GBM) cells by destabilizing the transcription factor SREBP2. Notably, TRAP1 inhibition induced cell death, which was rescued by cholesterol and mevalonate. Activation of liver X receptor (LXR) by a clinically validated …

- The United States is in a crisis of opiate related adverse events. From 1999 2017, more than 700,000 people in the U.S. died from drug related overdose; 68% of those involved opioids
- Admissions at Jefferson Hospital for opioid abuse complications are common among the medicine services. Treating patients for their opiate addiction is essential to prevent future opioid overdoses and other complications
- Jefferson has initiated an Opioid Aftercare Coordination Service (OACS) consult system in response to this crisis in order to increase the number of patients who receive medications for opioid use disorder on discharge
- OACS serves both Jefferson …

House Staff Quality Improvement and Patient Safety Conference (2016-2019)
Study Aims
- We aimed to improve the response times to inbox results of the residents and interns at Jefferson Internal Medicine Associates. A standard measure in EPIC is the percentage of inbox results responded to within 24 hours. At the time of project initiation, 50% of all results assigned to resident and intern inboxes were being responded to in this time frame . We aimed to improve this number to 70%
- There is no expectation that residents and interns could respond to all results within 24 hours. Trainee schedules are very crowded, and not all inbox results need to be …

House Staff Quality Improvement and Patient Safety Conference (2016-2019)
Introduction
- Patients with various lesions of the head and neck may have compromise of facial nerve function.
- Facial nerve (CN VII) has various roles, including movement of facial muscles and, importantly, eye closure.
- When facial nerve is sacrificed or damaged during a surgical cases, steps are often taken intraop to surgically correct the deficit and allow eye closure. However, these patients may not immediately realize the benefit of these interventions.
- In the postop period, appropriate eye care is critical to prevent exposure keratopathy due to inability to close eye.
- Exposure keratopathy is damage to the cornea that occurs primarily due …

Introduction
High quality chest compressions have been linked to improved survival from sudden cardiac arrest.
The 2015 AHA guidelines recommend the following:
- Rate of compressions between 100 120 CPM
- Depth of compressions between 2 2.4 inches
- Allow full recoil between compressions
- Target CPR fraction at least 60% of the time, ideally 80%
- Avoid hyperventilation
- Collect and use data to improve performance
We set out to show that our clinicians would have a minimum 25% improvement in CPR quality with the use of real time feedback using the new R series ZOLL defibrillators.

House Staff Quality Improvement and Patient Safety Conference (2016-2019)
Objective
Our objective was to look at the current protocol for spinal cord injury activation alerts and to highlight deficiencies in the system. Currently, any physician at Jefferson can call this alert, which often leads to a misuse of resources and wrongful identification of true spinal cord injury.
In order to refine the protocol, we believe that the Cord System should be used for the following guidelines:
- Identify patients w Spinal Cord Injury (SCI)
- Identify patients for SCI research trials
- Identify patients who require surgery
