Understanding How Patients Perceive Their Medical Providers’ Communication In A Hospital Based Emergency Department Setting, Balpreet K. Grewal-Virk

Seton Hall University Dissertations and Theses (ETDs)

Background: In recent years, a chief patient complaint has been that there is a breakdown in communication with their healthcare provider. This is concerning because poor provider-patient communication can lead to reduced medication adherence, misdiagnosis, increased healthcare costs, and even death. Furthermore, the implementation of the Affordable Care Act has availed healthcare insurance to more individuals, which will increase the insured patient population. This will lead to a rise in patient visits, but also means that there are not enough physicians to support this new volume of patients. Other healthcare providers, like nurse practitioners and physicians assistants are more …

Gonad: Genome-Editing Via Oviductal Nucleic Acids Delivery System: A Novel Microinjection Independent Genome Engineering Method In Mice., Gou Takahashi, Channabasavaiah B. Gurumurthy, Kenta Wada, Hiromi Miura, Masahiro Sato, Masato Ohtsuka

Journal Articles: Genetics, Cell Biology & Anatomy

Microinjection is considered the gold standard technique for delivery of nucleic acids (NAs; transgenes or genome editing tools such as CRISPR/Cas9 systems) into embryos, for creating genetically modified organisms. It requires sophisticated equipment as well as well-trained and highly skilled personnel to perform the micro-injection technique. Here, we describe a novel and simple microinjection-independent technique, called Genome-editing via Oviductal Nucleic Acids Delivery (GONAD). Using GONAD, we show that NAs (e.g., eGFP mRNA or Cas9 mRNA/sgRNAs) can be effectively delivered to pre-implantation embryos within the intact mouse oviduct by a simple electroporation method, and result in the desired genetic modification in …

Revised International Pediatric Non-Hodgkin Lymphoma Staging System, Angelo Rosolen, Sherrie L. Perkins, C Ross Pinkerton, R Paul Guillerman, John T. Sandlund, Catherine Patte, Alfred Reiter, Mitchell S. Cairo

NYMC Faculty Publications

PURPOSE: Treatment and prognosis of pediatric non-Hodgkin lymphoma (NHL) have improved dramatically in the last 30 years. However, the St Jude NHL staging classification for pediatric NHL was developed more than 35 years ago. The most recent Lugano lymphoma staging classification focused on adult lymphoma. Furthermore, major limitations of the current pediatric NHL staging classification include lack of consideration of new distinct pediatric NHL histologic entities; absence of recognition of frequent skin, bone, kidney, ovarian, and other organ involvement; and lack of newer precise methods to detect bone marrow and CNS involvement, minimal disease quantification, and highly sensitive imaging technologies. …

Irreversible Dual Inhibitory Mode: The Novel Btk Inhibitor Pls-123 Demonstrates Promising Anti-Tumor Activity In Human B-Cell Lymphoma., Ning Ding, Xitao Li, Yunfei Shi, Lingyan Ping, Lina Wu, Kai Fu, Lixia Feng, Xiaohui Zheng, Yuqin Song, Zhengying Pan, Jun Zhu

Journal Articles: Pathology and Microbiology

The B-cell receptor (BCR) signaling pathway has gained significant attention as a therapeutic target in B-cell malignancies. Recently, several drugs that target the BCR signaling pathway, especially the Btk inhibitor ibrutinib, have demonstrated notable therapeutic effects in relapsed/refractory patients, which indicates that pharmacological inhibition of BCR pathway holds promise in B-cell lymphoma treatment. Here we present a novel covalent irreversible Btk inhibitor PLS-123 with more potent anti-proliferative activity compared with ibrutinib in multiple cellular and in vivo models through effective apoptosis induction and dual-action inhibitory mode of Btk activation. The phosphorylation of BCR downstream activating AKT/mTOR and MAPK signal pathways …

International Pediatric Non-Hodgkin Lymphoma Response Criteria, John T. Sandlund, R Paul Guillerman, Sherrie L. Perkins, C Ross Pinkerton, Angelo Rosolen, Catherine Patte, Alfred Reiter, Mitchell S. Cairo

NYMC Faculty Publications

PURPOSE: Response criteria are well established for adult patients with non-Hodgkin lymphoma (NHL). A revised set of response criteria in adults with NHL was recently published. However, NHL in children and adolescents involves different histologies, primary sites of disease, patterns of metastatic spread, approaches to therapy, and responses to treatment compared with adult NHL. However, there are no standardized response criteria specific to pediatric NHL. Therefore, we developed international standardized methods for assessing response to therapy in children and adolescents with NHL. METHODS: An international multidisciplinary group of pediatric oncologists, pathologists, biologists, and radiologists convened during and after the Third …

Rasch Analysis Of The Patient Rated Elbow Evaluation Questionnaire, Joshua I. Vincent, Joy C. Macdermid, Graham J.W. King, Ruby Grewal

Bone and Joint Institute

© 2015 Vincent et al. Background: The Patient Rated Elbow Evaluation (PREE) was developed as an elbow joint specific measure of pain and disability and validated with classical psychometric methods. More recently, Rasch analysis has contributed new methods for analyzing the clinical measurement properties of self-report outcome measures. The objective of the study was to determine aspects of validity of the PREE using the Rasch model to assess the overall fit of the PREE data, the response scaling, individual item fit, differential item functioning (DIF), local dependency, unidimensionality and person separation index (PSI). Methods: A convenience sample of 236 patients …

Systemic siRNA administration to target and treat glioblastoma, one of the most deadly cancers, requires robust and efficient delivery platform without immunogenicity. Here we report newly emerged multivalent naked RNA nanoparticle (RNP) based on pRNA 3-way-junction (3WJ) from bacteriophage phi29 to target glioblastoma cells with folate (FA) ligand and deliver siRNA for gene silencing. Systemically injected FA-pRNA-3WJ RNPs successfully targeted and delivered siRNA into brain tumor cells in mice, and efficiently reduced luciferase reporter gene expression (4-fold lower than control). The FA-pRNA-3WJ RNP also can target human patient-derived glioblastoma stem cells, thought to be responsible for tumor initiation and deadly …

In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated …

Gould, Chrispin Chaguza, Chisomo Msefula, Jennifer E. Cornick, Benard W. Kulohoma, Katherine Gray, Stephen D. Bentley, Neil French, Robert S. Heyderman, Dean B. Everett

All Peer-Reviewed Publications

Background: Carriage of either single or multiple pneumococcal serotypes (multiple carriage) is a prerequisite for developing invasive pneumococcal disease. However, despite the reported high rates of pneumococcal carriage in Malawi, no data on carriage of multiple serotypes has been reported previously. Our study provides the first description of the prevalence of multiple pneumococcal carriage in Malawi. Methods: The study was conducted in Blantyre and Karonga districts in Malawi, from 2008 to 2012. We recruited 116 children aged 0-13 years. These children were either HIV-infected (N = 44) or uninfected (N = 72). Nasopharyngeal samples were collected using sterile swabs. Pneumococcal …

Procollagen C-Endopeptidase Enhancer Protein 2 (Pcpe2) Reduces Atherosclerosis In Mice By Enhancing Scavenger Receptor Class B1 (Sr-Bi)-Mediated High-Density Lipoprotein (Hdl)-Cholesteryl Ester Uptake, Ricquita D. Pollard, Christopher N. Blesso, Manal Zabalawi, Brian Fulp, Mark Gerelus, Xuewei Zhu, Erica W. Lyons, Nebil Nuradin, Omar L. Francone, Xiang-An Li, Daisy Sahoo, Michael J. Thomas, Mary G. Sorci-Thomas

Pediatrics Faculty Publications

Studies in human populations have shown a significant correlation between procollagen C-endopeptidase enhancer protein 2 (PCPE2) single nucleotide polymorphisms and plasma HDL cholesterol concentrations. PCPE2, a 52-kDa glycoprotein located in the extracellular matrix, enhances the cleavage of C-terminal procollagen by bone morphogenetic protein 1 (BMP1). Our studies here focused on investigating the basis for the elevated concentration of enlarged plasma HDL in PCPE2-deficient mice to determine whether they protected against diet-induced atherosclerosis. PCPE2-deficient mice were crossed with LDL receptor-deficient mice to obtain LDLr^-/-, PCPE2^-/- mice, which had elevated HDL levels compared with LDLr^-/- mice with similar …

Homophily, Close Friendship, And Life Satisfaction Among Gay, Lesbian, Heterosexual, And Bisexual Men And Women, Brian Joseph Gillespie, David Frederick, Lexi Harari, Christian Grov

Publications and Research

Friends play important roles throughout our lives by providing expressive, instrumental, and companionate support. We examined sexual orientation, gender, and age differences in the number of friends people can rely on for expressive, instrumental, and companionate support. Additionally, we examined the extent to which people relied on same-gender versus cross-gender friends for these types of support. Participants (N = 25,185) completed a survey via a popular news website. Sexual orientation differences in number of same-gender and cross-gender friends were generally small or non-existent, and satisfaction with friends was equally important to overall life satisfaction for all groups. However, the extent …

Increased Expression Of Simple Ganglioside Species Gm2 And Gm3 Detected By Maldi Imaging Mass Spectrometry In A Combined Rat Model Of A Beta Toxicity And Stroke, Sarah Caughlin, Jeffrey D. Hepburn, Dae Hee Park, Kristina Jurcic, Ken K. -C. Yeung, David F. Cechetto, Shawn N. Whitehead

Anatomy and Cell Biology Publications

The aging brain is often characterized by the presence of multiple comorbidities resulting in synergistic damaging effects in the brain as demonstrated through the interaction of Alzheimer's disease (AD) and stroke. Gangliosides, a family of membrane lipids enriched in the central nervous system, may have a mechanistic role in mediating the brain's response to injury as their expression is altered in a number of disease and injury states. Matrix-Assisted Laser Desorption Ionization (MALDI) Imaging Mass Spectrometry (IMS) was used to study the expression of A-series ganglioside species GD1a, GM1, GM2, and GM3 to determine alteration of their expression profiles in …

Nutrition Support Nursing Handoff: A Computerized Template, Suzanne L. Bundrick

Theses and Graduate Projects

At a large Midwest private nutrition support practice, a manual reporting tool has been the communication practice used in daily handoff practices. For patients who require consultation from the Nutrition Support Consulting Service, accurate communication of the nutrition plan of care among members of the health care team is a critical element of patient care and safety. Because communication errors are a leading cause of sentinel events for patients, having a safe transfer of care from nurse to nurse each day is imperative. A nutrition support computerized handoff template not only creates continuity of care among team members, it also …

Understanding Factors Contributing To Risky Sexual Activity In The Study Abroad Environment, Tiffany Marcantonio

Theses and Dissertations

Researchers suggest that study abroad students may be an un-identified high risk group for risky sexual activity. The goal of this study was to determine whether factors predictive of risky sexual activity at home (sexual sensation seeking, alcohol and sex expectancies, alcohol consumption and previous risky behaviors) may also influence such behavior while abroad. Data was collected longitudinally with a pre and post survey that assessed the above constructs. Twenty-four study abroad students completed the pre survey and six completed the post survey. Two Independent samples t-tests were conducted to clarify differences between gender and students who completed the pre-survey …

Chromatin To Clinic: The Molecular Rationale For Parp1 Inhibitor Function., Felix Y. Feng, Johann S. De Bono, Mark A. Rubin, Karen E Knudsen

Department of Cancer Biology Faculty Papers

Poly(ADP-ribose) polymerase 1 (PARP1) inhibitors were recently shown to have potential clinical impact in a number of disease settings, particularly as related to cancer therapy, treatment for cardiovascular dysfunction, and suppression of inflammation. The molecular basis for PARP1 inhibitor function is complex, and appears to depend on the dual roles of PARP1 in DNA damage repair and transcriptional regulation. Here, the mechanisms by which PARP-1 inhibitors elicit clinical response are discussed, and strategies for translating the preclinical elucidation of PARP-1 function into advances in disease management are reviewed.

Telemetric Blood Pressure Assessment In Angiotensin Ii-Infused Apoe-/- Mice: 28 Day Natural History And Comparison To Tail-Cuff Measurements, Christopher M. Haggerty, Andrea C. Mattingly, Ming C. Gong, Wen Su, Alan Daugherty, Brandon K. Fornwalt

Saha Cardiovascular Research Center Faculty Publications

Abdominal aortic aneurysm (AAA) is a disease of the aortic wall, which can progress to catastrophic rupture. Assessment of mechanical characteristics of AAA, such as aortic distensibility, may provide important insights to help identify at-risk patients and understand disease progression. While the majority of studies on this topic have focused on retrospective patient data, recent studies have used mouse models of AAA to prospectively evaluate the evolution of aortic mechanics. Quantification of aortic distensibility requires accurate measurement of arterial blood pressure, particularly pulse pressure, which is challenging to perform accurately in murine models. We hypothesized that volume/pressure tail-cuff measurements of …

Induced Ankylosis Of A Primary Molar For Skeletal Anchorage In The Mandible As Alternative To Mini-Implants, Matina V. Angelopoulou, Despina Koletsi, George Vadiakas, Demetrios J. Halazonetis

School of Dentistry Faculty Research and Publications

Background

Mesial protraction of mandibular posterior teeth requires increased anchorage to avoid undesired tooth movements. Orthodontic mini-implants have become a popular and successful way to increase skeletal anchorage in such cases. However, mini-implants may cause injury to adjacent teeth or anatomical structures and may lead to tissue inflammation. Induced ankylosed primary teeth have been used in the past as abutments for the protraction of the maxilla in cases of maxillary retrognathism. However, this technique has not been described in the literature for the protraction of mandibular molars. The aim of this paper is to present, through a case report, an …

Antibacterial Characterization Of Novel Synthetic Thiazole Compounds Against Methicillin-Resistant Staphylococcus Pseudintermedius, Haroon Mohammad, P.V. N. Reddy, Dennis Monteleone, Abdelrahman S. Mayhoub, Mark S. Cushman, G. Kenitra Hammac, Mohamed N. Seleem

Department of Comparative Pathobiology Faculty Publications

Staphylococcus pseudintermedius is a commensal organism of companion animals that is a significant source of opportunistic infections in dogs. With the emergence of clinical isolates of S. pseudintermedius (chiefly methicillin-resistant S. pseudintermedius (MRSP)) exhibiting increased resistance to nearly all antibiotic classes, new antimicrobials and therapeutic strategies are urgently needed. Thiazole compounds have been previously shown to possess potent antibacterial activity against multidrug-resistant strains of Staphylococcus aureus of human and animal concern. Given the genetic similarity between S. aureus and S. pseudintermedius, this study explores the potential use of thiazole compounds as novel antibacterial agents against methicillin-sensitive S. pseudintermedius (MSSP) and …

Structure-Based Redesign Of Lysostaphin Yields Potent Antistaphylococcal Enzymes That Evade Immune Cell Surveillance, Kristina Blazanovic, Hongliang Zhao, Yoonjoo Choi, Wen Li, Regina S. Salvat, Daniel C. Osipovitch, Jennifer Fields, Leonard Moise, Brent L. Berwin, Steven N. Fiering, Chris Bailey-Kellogg, Karl E. Griswold

Dartmouth Scholarship

Staphylococcus aureus infections exert a tremendous burden on the health-care system, and the threat of drug-resistant strains continues to grow. The bacteriolytic enzyme lysostaphin is a potent antistaphylococcal agent with proven efficacy against both drug-sensitive and drug-resistant strains; however, the enzyme's own bacterial origins cause undesirable immunogenicity and pose a barrier to clinical translation. Here, we deimmunized lysostaphin using a computationally guided process that optimizes sets of mutations to delete immunogenic T cell epitopes without disrupting protein function. In vitro analyses showed the methods to be both efficient and effective, producing seven different deimmunized designs exhibiting high function and …

Testing Multiple Hypotheses Through Imp Weighted Fdr Based On A Genetic Functional Network With Application To A New Zebrafish Transcriptome Study, Jiang Gui, Casey S. Greene, Con Sullivan, Walter Taylor, Jason H. Moore, Carol Kim

Dartmouth Scholarship

In genome-wide studies, hundreds of thousands of hypothesis tests are performed simultaneously. Bonferroni correction and False Discovery Rate (FDR) can effectively control type I error but often yield a high false negative rate. We aim to develop a more powerful method to detect differentially expressed genes. We present a Weighted False Discovery Rate (WFDR) method that incorporate biological knowledge from genetic networks. We first identify weights using Integrative Multi-species Prediction (IMP) and then apply the weights in WFDR to identify differentially expressed genes through an IMP-WFDR algorithm. We performed a gene expression experiment to identify zebrafish genes that change expression …
