Stat3 Genotypic Variant Rs744166 And Increased Tyrosine Phosphorylation Of Stat3 In Il-23 Responsive Innate Lymphoid Cells During Pathogenesis Of Crohn's Disease, Ying Tang, Sanda A. Tan, Atif Iqbal, Jian Li, Sarah C. Glover

Department of Neurology Faculty Papers

Crohn's disease (CD) results from dysregulated immune responses to gut microbiota in genetically susceptible individuals, affecting multiple areas of the gastrointestinal tract. Innate lymphoid cells (ILCs) are tissue-resident innate effector lymphocytes which play crucial roles in mucosal immune defense, tissue repair, and maintenance of homeostasis. The accumulation of IFN-γ-producing ILC1s and increased level of proinflammatory cytokines produced by ILCs has been observed in the inflamed terminal ileum of CD patients. To date, the precise mechanisms of ILC plasticity and gene regulatory pathways in ILCs remain unclear. Signal transducer and activator of transcription 3 (STAT3) regulates gene expression in …

Markey Cancer Center Faculty Publications

Chronic migraine is a frequent and debilitating condition affecting 14% of the general population. This prospective observational pilot study investigated whether men with chronic migraine have lower than expected total serum testosterone levels. We identified 14 men ages 26-51 at our Institution who fulfilled the ICHD-3b criteria for chronic migraine and obtained serum total testosterone levels. The mean total testosterone level in our 14 patients was 322 ng/dL (range: 120-542 ng/dL) which is in the lower 5% of the reference range for our laboratory (300-1080 ng/dL). Men with chronic migraine had lower total testosterone levels compared to published agematched normative …

Immunomodulatory And Neuroprotective Mechanisms Of Huangqi Glycoprotein Treatment In Experimental Autoimmune Encephalomyelitis., Yanxia Xing, Binyu Liu, Yijin Zhao, Lihong Zhang, Rodolfo Thome, Huiqing Xue, Peijun Zhang, Cungen Ma

Department of Neurology Faculty Papers

Previous studies have shown that Huangqi glycoprotein (HQGP) has an anti-inflammatory effect in vitro, and suppressed experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis; however, the mechanism underlying its effect is largely unknown. In this manuscript we investigated the mechanisms by which HQGP protect mice from EAE. HQGP was extracted from Astragalus membranaceus and purified by anion-exchange and gel filtration chromatography. HQGP delayed disease onset, reduced disease severity and alleviated inflammation and demyelination in the central nervous system (CNS). Moreover, HQGP reduced the infiltration of pathogenic immune cells and increased the expression of microtubule-associated protein 2 (MAP-2) and …

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.

Neuroimaging Protocol In Patients Presenting With Spontaneous Intracerebral Hemorrhage, Kevin Hines, Md, Nikolaos Mouchtouris, Md, Karim Hafazalla, Jacob M. Mazza, Phillip Phan, Giuliana Labella, Muhammad Athar, Md, Adam Flanders, Md, Pascal Jabbour, Md

House Staff Quality Improvement and Patient Safety Conference (2016-2019)

Introduction

While lacking evidence based recommendations, most institutions must evaluate spontaneous intracerebral hemorrhages (sICH) for hematoma expansion (HE). If unrecognized, it can be a devastating complication. However, because of the lack of general recommendations for serial imaging, many hospitals, including Thomas Jefferson, have arbitrarily instituted 6 hour an 24 hour stability head CT’s to evaluate for HE.

In our project, we examine the impact of this imaging protocol on the safety and quality of patient care and provide revised recommendations for imaging in sICH at Thomas Jefferson University Hospital and Jefferson Hospital for Neuroscience.

Spinal Cord Injury Activation Alert: Revisiting And Revamping Protocols, Ritam Ghosh, Md, Ralph Marino, Md, Michael Wolf, Md, James S. Harrop, Md

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:

1. Identify patients w Spinal Cord Injury (SCI)
2. Identify patients for SCI research trials
3. Identify patients who require surgery

Developing A Neurosurgical Spine Post-Operative Note Template On Epic For Improved Multi-Disciplinary Care, Omaditya Khanna, Md, Geoffrey P. Stricsek, Md, Giuliana Labella, Rn, James Harrop, Md, Jesse Edwards, Md

House Staff Quality Improvement and Patient Safety Conference (2016-2019)

Introduction

The care of neurosurgical spine patients often involves a multi-disciplinary team, including neurosurgery residents, hospitalists, nursing staff, and physical/occupational therapists.

Oftentimes, post-op spine patients are on a non-neurosurgical service (hospitalist, MICU/SICU, medicine), who are provided with scant sign out on the procedure(s) performed.

The treatment team(s) that are helping manage patient care post-operatively are often unaware of the procedure performed, and what are the salient clinical signs/symptoms, radiographic findings, and laboratory values that need to be closely monitored

Generation Of Oligodendrocyte Progenitor Cells From Mouse Bone Marrow Cells., Yuan Zhang, Xin-Yu Lu, Giacomo Casella, Jing Tian, Ze-Qing Ye, Ting Yang, Juan-Juan Han, Ling-Yu Jia, A. M. Rostami, Xing Li

Department of Neurology Faculty Papers

Oligodendrocyte progenitor cells (OPCs) are a subtype of glial cells responsible for myelin regeneration. Oligodendrocytes (OLGs) originate from OPCs and are the myelinating cells in the central nervous system (CNS). OLGs play an important role in the context of lesions in which myelin loss occurs. Even though many protocols for isolating OPCs have been published, their cellular yield remains a limit for clinical application. The protocol proposed here is novel and has practical value; in fact, OPCs can be generated from a source of autologous cells without gene manipulation. Our method represents a rapid, and high-efficiency differentiation protocol for generating …

Serum Biomarkers For Glioblastoma Multiforme, Ayesha Quddusi, Muhammad Shahzad Shamim

Section of Neurosurgery

A number of different serum biomarkers are currently being evaluated for their potential use as diagnostic and prognostic biomarkers in Glioblastoma Multiforme. Amongst these, a vast number of different microRNAs have been studied, that are up-regulated or downregulated in relation to Glioblastoma Multiforme. Different studies have found numerous associations of these different microRNAs with recurrence, Karnofsky Performance Score, Progression Free Survival and Overall Survival. Other than microRNAs, serum Glial Fibrillary Acid Protein, cytokines and YLK-40, as well as a number of other candidate serum biomarkers are being studied.More studies, with larger sample sizes are required before these serum biomarkers can …

Polyneuropathy Associated With Iga Paraproteinemia: A Case Report And Literature Review., Waleed Shahzad, Sumaira Nabi, Hafiza Faiza Mushtaq, Tehmina Inayat, Muhammad Hassan, Haris Majid Rajput, Zakir Jan, Mazhar Badshah

Pakistan Journal of Neurological Sciences (PJNS)

Paraproteinemia is precipitated by an accumulation of monoclonal plasma cells or B lymphocytes. Idiopathic neuropathies that are associated with paraproteinemia account for only 10% of the neuropathies. Paraprotein acts like an antibody and is targeted against myelin and axons present in the peripheral nerves. Despite being of interest for quite a long time, the caudal relationship between paraproteinemias and peripheral neuropathies still remains a sorcery. We report a case of a middle aged male who presented with pain and parasthesias in both arms and legs. His workup revealed him to be having a paraproteinemic neuropathy consistent with IgA Lambda chains …

Humanism And Mental Health Of Married Female Patients With Systemic Lupus Erythematosus., Hafiza Muzammal Shafiq, Dr. Muhammad Rafiq, Dr. Zahid Mahmood

Pakistan Journal of Neurological Sciences (PJNS)

Autoimmune diseases exert adverse impact on the psychological, social and physical well-being of the individuals who suffer from such diseases. Systemic lupus erythematosus is one of chronic illnesses that disturb the all areas of life especially psychosocial perspective of life. In such conditions, belief and view of patients about their own self is necessary to prognosis of their health. Studies suggest that humanism is one of those protective factors that can lead risky health towards better life.

Although seizures have a higher incidence in neonates than any other age group and are associated with significant mortality and neurodevelopmental disability, treatment is largely guided by physician preference and tradition, due to a lack of data from well-designed clinical trials. There is increasing interest in conducting trials of novel drugs to treat neonatal seizures, but the unique characteristics of this disorder and patient population require special consideration with regard to trial design. The Critical Path Institute formed a global working group of experts and key stakeholders from academia, the pharmaceutical industry, regulatory agencies, neonatal nurse associations, and patient advocacy …
