Study Of The Cytological Features Of Bone Marrow Mesenchymal Stem Cells From Patients With Neuromyelitis Optica., Chunsheng Yang, Yang Yang, Li Ma, Guang-Xian Zhang, Fu-Dong Shi, Yaping Yan, Guoqiang Chang Mar 2019

Study Of The Cytological Features Of Bone Marrow Mesenchymal Stem Cells From Patients With Neuromyelitis Optica., Chunsheng Yang, Yang Yang, Li Ma, Guang-Xian Zhang, Fu-Dong Shi, Yaping Yan, Guoqiang Chang

Department of Neurology Faculty Papers

Neuromyelitis optica (NMO) is a refractory autoimmune inflammatory disease of the central nervous system without an effective cure. Autologous bone marrow‑derived mesenchymal stem cells (BM‑MSCs) are considered to be promising therapeutic agents for this disease due to their potential regenerative, immune regulatory and neurotrophic effects. However, little is known about the cytological features of BM‑MSCs from patients with NMO, which may influence any therapeutic effects. The present study aimed to compare the proliferation, differentiation and senescence of BM‑MSCs from patients with NMO with that of age‑ and sex‑matched healthy subjects. It was revealed that there ...

A Systematic Review Of Clinical Outcomes In Motorcycle Injuries In Low & Middle-Income Countries, Lydia Huang, Myles Dworkin, Elizabeth Krebs, Md Feb 2019

A Systematic Review Of Clinical Outcomes In Motorcycle Injuries In Low & Middle-Income Countries, Lydia Huang, Myles Dworkin, Elizabeth Krebs, Md

Phase 1

Injuries due to road traffic accidents account for over 1 million deaths annually, of which 90% disproportionately occur in low and middle-income countries (LMICs). In their current design, motorcycle helmets notably improve patient outcomes, reducing the risk of crash-related TBIs by 69% and death by 42%. The data we currently have does not thoroughly document the large burden of road traffic injuries in LMICs, and thus we must identify what specific clinical outcomes have been documented in relation to helmeted accidents in LMICs. Collection of clinical outcomes data can serve as the evidence-based framework needed for future injury prevention efforts ...


Effect Of Tort Reform On Diagnostic Imaging Rates, Israel Ojalva, Ba, Arthur Hong, Md, Mph Feb 2019

Effect Of Tort Reform On Diagnostic Imaging Rates, Israel Ojalva, Ba, Arthur Hong, Md, Mph

Phase 1

Introduction: Defensive medicine, is defined as “order[ing] tests, procedures, or visits, or avoid certain high-risk patients or procedures, primarily (but not solely) because of concern about malpractice liability.” Nearly all physician who fear malpractice litigation have admitted to practicing some degree of defensive medicine. In response, many states have enacted policy reforms to lighten the threat of malpractice on physicians.

Objective: The most common defensive medicine behavior is ordering diagnostic imaging tests when it is potentially unwarranted. Many states have enacted non-economic damage caps from 2000-2010. We explored if these laws had an impact on the rates of diagnostic ...

The Impact Of Student Hotspotting On Patients & The Jefferson Health System, Mishael Khan, Bs, Lauren Collins, Md, Shoshana Sicks, Edm, Richard Hass, Phd, Tracey Vause Earland, Phd, Otr/L, Courtney Newsome, Ba, Sara Cohen, Ots

Phase 1

Introduction

“Super-utilizers”, patients with five or more hospital admissions in the past year, account for half of all healthcare expenditures and present a significant financial burden to our healthcare system. In Pennsylvania “super-utilizers” result in $1.25 billion of healthcare spending and Philadelphia has the highest number of “super-utilizers” in the state. To address this crisis, Jefferson University serves as one of four new national hubs for student hotspotting. Teams of interprofessional health professions students along with faculty and staff advisors enroll “super-utilizers” and provide targeted interventions to address social determinants of health, reduce hospitalizations and improve patient outcomes.

Enhancing Services For Homeless Populations: Impact Of A Virtual-Reality Training Tool On Health Professional Students’ Self-Efficacy In Working With Homeless Populations, Madeline Russell, Susan Toth-Cohen, Phd, Otr/L Feb 2019

Enhancing Services For Homeless Populations: Impact Of A Virtual-Reality Training Tool On Health Professional Students’ Self-Efficacy In Working With Homeless Populations, Madeline Russell, Susan Toth-Cohen, Phd, Otr/L

Phase 1

INTRODUCTION

Despite the rising prevalence and unmet healthcare needs of homeless populations, most healthcare providers do not receive specific training on working with this population. The growth of simulation-based technology in the medical classroom offers new opportunities for such training. Virtual-reality tools have been shown to facilitate learning and minimize restraints such as time and travel. The Enhancing Service to Homeless Populations (ESHP) program was designed to provide health professions students at Thomas Jefferson University with training on how to interact with homeless populations using an interprofessional virtual-reality setting, with the ultimate goal of improving students’ self-efficacy.

Identifying The Causes Of Cancer Readmissions: A Patient Centered Approach, Katie Holland, Emily Wei, Allison Zibelli Feb 2019

Identifying The Causes Of Cancer Readmissions: A Patient Centered Approach, Katie Holland, Emily Wei, Allison Zibelli

Phase 1

While there are large efforts to decrease readmission rates in the United States, cancer patients represent a population that has been overlooked. Cancer patients are a vulnerable population who make up a large portion of hospital readmissions. Most of the current research on the causes of readmissions in cancer patients focuses on medical chart reviews and insurance claims. Many of these studies fail to incorporate patient input which could further the understanding of the complete burden associated with cancer readmissions. The goal of this study is to understand the personal reasons behind the decision of cancer patients to return to ...

Outcomes Reporting In Regional Anesthesia Patients: A Comparison Of Manual Phone Calls Versus Automated Phone App Messaging, Gavyn Ooi, Eric Schwenk, Md, Fasa, Jeffrey Mojica, Do, Alexander Grant, Md, Max Shilling, Md, David Barnabei, Md, Jennifer Lessin, Ba, Rn, Ccrc, Marc Torjman, Phd, Kent Berg, Md, Mba

Phase 1

Automation of patient follow-up via mobile phone apps have the potential to save time for physicians, standardize responses from patients, and increase the patient response rate. Studies that assess the effectiveness of mobile phone-based surveys have been favorable, with completion rates of about 60% in the surgical population. The impact of mobile phone-based patient management in anesthesia deserves further study. This study examines the follow-up success rates of (1) manual phone calls (the current standard of care) vs. (2) automated patient outreach (APO) in patients who receive a regional anesthesia block procedure.

As part of normal follow up, anesthesia team ...


Mindfulness-Based Stress Reduction Intervention For The Treatment Of Chronic Pain In The Elderly, Austin Roadarmel, Diane Reibel, Phd, Aleeze Moss, Phd, Andrew Newberg, Md Feb 2019

Mindfulness-Based Stress Reduction Intervention For The Treatment Of Chronic Pain In The Elderly, Austin Roadarmel, Diane Reibel, Phd, Aleeze Moss, Phd, Andrew Newberg, Md

Phase 1

One of the most common complaints of adults in their 80s and above, a growing portion of our population, is chronic pain and it is often inadequately treated. A secular mindfulness-based stress reduction (MBSR) program was developed by Jon Kabat-Zinn in 1979 and has since shown measurable benefits to individuals in decreasing depression, pain, and anxiety. Considering the significant risk of side effects and age-associated changes of pharmacodynamics and pharmacokinetics in the traditional pharmacologic approach to chronic pain in the elderly, non-pharmacologic intervention such as MBSR may be particularly effective for the elderly population.

Methods: We conducted a 6 week ...

Silicosis is a common occupational disease and represents a significant contributor to respiratory morbidity and mortality worldwide. Lipid-laden macrophages, or foam cells, are observed in the lungs of patients with silicosis but the mechanisms mediating their formation remain poorly understood. In this study, we sought to elucidate the mechanisms by which silica promotes foam cell formation in the lung, and to determine whether uptake of lipids alone is sufficient to drive TGF-β production by alveolar macrophages. Consistent with previous reports, we found that foam cells were markedly increased in the lungs of patients with silicosis and that these findings associated ...

Department of Neurosurgery Faculty Papers

Imaging in the field of epilepsy surgery remains an essential tool in terms of its ability to identify regions where the seizure focus might present as a resectable area. However, in many instances, an obvious structural abnormality is not visualized. This has created the opportunity for new approaches and imaging innovation in the field of epilepsy, such as with Diffusion Tensor Imaging (DTI) and Diffusion Tensor Tractography (DTT). In this study, we aim to evaluate the use of DTI and DTT as a predictive model in the field of epilepsy, specifically Temporal Lobe Epilepsy (TLE), and correlate their clinical significance ...

Coronary angiography (CA) is the basis of an invasive management strategy in non-ST elevation acute coronary syndromes (NSTEACS). There are limited contemporary data on national temporal trends in utilization of CA in different patient subgroups. We sought to investigate temporal trends, predictors and clinical outcomes associated with the use of CA in the US. Using the Nationwide Inpatient Sample (NIS) from 2004–2014, we identified all inpatient admissions, age ≥18, with a primary diagnosis of NSTEACS. Descriptive statistics and multivariable logistic regression models were used to investigate temporal trends, predictors and clinical outcomes associated with CA. From a total of ...

Model-Based Virtual Patient Analysis Of Human Liver Regeneration Predicts Critical Perioperative Factors Controlling The Dynamic Mode Of Response To Resection., Babita Verma, Pushpavanam Subramaniam, Rajanikanth Vadigepalli Jan 2019

Model-Based Virtual Patient Analysis Of Human Liver Regeneration Predicts Critical Perioperative Factors Controlling The Dynamic Mode Of Response To Resection., Babita Verma, Pushpavanam Subramaniam, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Liver has the unique ability to regenerate following injury, with a wide range of variability of the regenerative response across individuals. Existing computational models of the liver regeneration are largely tuned based on rodent data and hence it is not clear how well these models capture the dynamics of human liver regeneration. Recent availability of human liver volumetry time series data has enabled new opportunities to tune the computational models for human-relevant time scales, and to predict factors that can significantly alter the dynamics of liver regeneration following a resection.

METHODS: We utilized a mathematical model that integrates signaling ...


Impaired Nuclear Export Of Polyglutamine-Expanded Androgen Receptor In Spinal And Bulbar Muscular Atrophy., Frederick J. Arnold, Anna Pluciennik, Diane E. Merry Jan 2019

Impaired Nuclear Export Of Polyglutamine-Expanded Androgen Receptor In Spinal And Bulbar Muscular Atrophy., Frederick J. Arnold, Anna Pluciennik, Diane E. Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disease caused by polyglutamine (polyQ) expansion in the androgen receptor (AR). Prior studies have highlighted the importance of AR nuclear localization in SBMA pathogenesis; therefore, in this study, we sought to determine the role of AR nuclear export in the pathological manifestations of SBMA. We demonstrate here that the nuclear export of polyQ-expanded AR is impaired, even prior to the formation of intranuclear inclusions of aggregated AR. Additionally, we find that promoting AR export with an exogenous nuclear export signal substantially reduces its aggregation and blocks hormone-induced toxicity. Moreover, we show ...


The Doctor's Office Is The Best Setting For Most Cutaneous Procedures., Hannah J. Anderson, Matthew Keller Jan 2019

The Doctor's Office Is The Best Setting For Most Cutaneous Procedures., Hannah J. Anderson, Matthew Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

Although most dermatologic procedures are done in an office setting, some providers are performing them instead in ambulatory surgery centers (ASCs). This relocation of care comes with significantly higher expenses for patients and insurers. Compounding the issue of increased costs is the paucity of evidence demonstrating better outcomes associated with the use of ASCs. The most common cutaneous procedures have low complication rates when performed in an office setting and regular use of ASCs for these procedures is not justified.


Choline Is An Intracellular Messenger Linking Extracellular Stimuli To Ip3-Evoked Ca2+ Signals Through Sigma-1 Receptors, Eugen Brailoiu, Sumita Chakraborty, G. Cristina Brailoiu, Pingwei Zhao, Jeffrey L. Barr, Marc A. Ilies, Ellen M. Unterwald, Mary E. Abood, Colin W. Taylor Jan 2019

Choline Is An Intracellular Messenger Linking Extracellular Stimuli To Ip3-Evoked Ca2+ Signals Through Sigma-1 Receptors, Eugen Brailoiu, Sumita Chakraborty, G. Cristina Brailoiu, Pingwei Zhao, Jeffrey L. Barr, Marc A. Ilies, Ellen M. Unterwald, Mary E. Abood, Colin W. Taylor

College of Pharmacy Faculty Papers

Sigma-1 receptors (Sig-1Rs) are integral ER membrane proteins. They bind diverse ligands, including psychoactive drugs, and regulate many signaling proteins, including the inositol 1,4,5-trisphosphate receptors (IP3Rs) that release Ca2+ from the ER. The endogenous ligands of Sig-1Rs are unknown. Phospholipase D (PLD) cleaves phosphatidylcholine to choline and phosphatidic acid (PA), with PA assumed to mediate all downstream signaling. We show that choline is also an intracellular messenger. Choline binds to Sig-1Rs, it mimics other Sig-1R agonists by potentiating Ca2+ signals evoked by IP3Rs, and it is deactivated by metabolism. Receptors, by stimulating ...

DACH1 abundance is reduced in human malignancies, including breast cancer. Herein DACH1 was detected among multipotent fetal mammary stem cells in the embryo, among mixed lineage precursors, and in adult basal cells and (ERα+) luminal progenitors. Dach1 gene deletion at 6 weeks in transgenic mice reduced ductal branching, reduced the proportion of mammary basal cells (Lin CD24med CD29high) and reduced abundance of basal cytokeratin 5, whereas DACH1 overexpression induced ductal branching, increased Gata3 and Notch1, and expanded mammosphere formation in LA-7 breast cells. Mammary gland-transforming growth factor β (TGF-β) activity, known to reduce ductal branching and to reduce ...

Department of Orthopaedic Surgery Faculty Papers

Inactive mammalian tolloid-like 1 (tll1) and mutations detected in tolloid-like 1 (TLL1) have been linked to the lack of the heart septa formation in mice and to a similar human inborn condition called atrial-septal defect 6 (ASD6; OMIM 613087, formerly ASD II). Previously, we reported four point mutations in TLL1 found in approximately 20% of ASD6 patients. Three mutations in the coding sequence were M182L, V238A, and I629V. In this work, we present the effects of these mutations on TLL1 function. Three recombinant cDNA constructs carrying the mutations and one wild-type construct were prepared and then expressed in HT-1080 cells ...
