A Structured Telephonic Transition Program For Heart Failure Patients, Julia E. Robinson

Doctor of Nursing Practice Final Manuscripts

HF is a fatal condition affecting more than 5 million Americans leading to frequent hospitalizations, poor quality of life and death. The annual cost to the healthcare system is approximately $38 billion, ranking HF as one of the costliest conditions to manage. Significant evidence exists that HF self-care management programs improve patient self-care and decrease HF-related readmissions. Current guidelines recommend health professionals provide comprehensive HF education focused on knowledge, skills of management, and self-care behaviors.

The Iowa Model of Evidence Based Practice provided the foundation for the practice change. Structured telephonic support (STS) was based on Bandura’s Self- Efficacy behavior …

Health Care Transition Program For Adolescents With Spina Bifida, Teresa M. Scavone

Doctor of Nursing Practice Final Manuscripts

The purpose of this evidence-based project was to evaluate the feasibility of implementing an NP facilitated formal transition program for adolescents with Spina Bifida. There is an increased awareness of the need for health care transition for youth with special health care needs (YSHCN) due to the 2009-2010 Maternal Child Health Branch National Survey findings that only 40% of YSHCN receive adequate support for transition that meets the core outcome measures. Recent studies have investigated transition in youth with chronic disease specific conditions such as diabetes, cystic fibrosis, and congenital heart defects, and provide valuable insight into possible strategies for …

Doctor of Nursing Practice Final Manuscripts

ABSTRACT

Experts in asthma care globally recommend screening for asthma control in all patients with asthma through the use of an evidence-based tool. This project embedded the Asthma Control Test (ACT) in the electronic health record to determine if screening for control would change compared to standard care.

Methods

An electronic template of the ACT was embedded in the electronic health record system for a community faith-based family medicine clinic. All patients 12 years and older with a previous diagnosis of asthma were included in this project. These patients were screened for asthma control using the template at every appointment. …

Phylogenetic Analysis Of Human Cytomegalovirus Pus27 And Pus28: Ascertaining An Independent Or Linked Evolutionary History, Jessica A. Scarborough

Undergraduate Honors Theses

Human cytomegalovirus (HCMV) is a widespread pathogen that is particularly skilled at evading immune detection and defense mechanisms, largely due to extensive co-evolution with its host’s immune system. One aspect of this co-evolution involves the acquisition of four virally encoded GPCR chemokine receptor homologs, products of the US27, US28, UL33 and UL78 genes. G protein-coupled receptors (GPCR) are the largest family of cell surface proteins, found in organisms from yeast to humans. In this research, phylogenetic analysis was used to investigate the origins of the US27 and US28 genes, which are adjacent in the viral genome. The results indicate that …

The world is becoming increasingly vulnerable to pandemics resulting from globalization, urbanization, intense human/animal interchange, and climate change. A series of global health crises have emerged since 2000, ranging from Severe Acute Respiratory Syndrome (SARS) and its phylogenetic cousin Middle East Respiratory Syndrome (MERS), to pandemic Influenza A (H1N1), Ebola, and the ongoing Zika virus epidemic. The Ebola epidemic gave rise to four global commissions proposing a bold new agenda for global health preparedness and response for future infectious disease threats.

Four global commissions reviewing the recent Ebola virus disease epidemic response consistently recommended strengthening national health systems, consolidating and …

Hiv-1 Genetic Variation Resulting In The Development Of New Quasispecies Continues To Be Encountered In The Peripheral Blood Of Well-Suppressed Patients., Will Dampier, Michael R Nonnemacher, Joshua Mell, Joshua Earl, Garth D Ehrlich, Vanessa Pirrone, Benjamas Aiamkitsumrit, Wen Zhong, Katherine Kercher, Shendra Passic, Jean W Williams, Jeffrey M Jacobson, Brian Wigdahl

Kimmel Cancer Center Faculty Papers

As a result of antiretroviral therapeutic strategies, human immunodeficiency virus type 1 (HIV-1) infection has become a long-term clinically manageable chronic disease for many infected individuals. However, despite this progress in therapeutic control, including undetectable viral loads and CD4+ T-cell counts in the normal range, viral mutations continue to accumulate in the peripheral blood compartment over time, indicating either low level reactivation and/or replication. Using patients from the Drexel Medicine CNS AIDS Research and Eradication Study (CARES) Cohort, whom have been sampled longitudinally for more than 7 years, genetic change was modeled against to the dominant integrated proviral quasispecies with …

A subset of 199 children contributed additional asymptomatic samples (2307) and diarrheal stools (770), which were used to derive incidence rates and evaluate evidence for acquired immunity.
Results: Across sites, 89% of children experienced at least 1 norovirus infection before 24 months, and 22.7% of all diarrheal stools were norovirus positive. Severity of norovirus-positive diarrhea was …

The Utility Of Remote Hemodynamic Monitoring Devices In Patients With A Ventricular Assist Device, Bennet George, Amanda Hart, Sarah Branam, Maya Guglin

The VAD Journal

Remote intracardiac hemodynamic monitoring is a growing area of interest to help aid in the management of patients with chronic congestive heart failure. The utility of remote hemodynamic monitoring has not previously been investigated with a ventricular assist device population. We present two cases of patients with ventricular assist devices in which we employed remote hemodynamic monitoring data to aid in patient management.

Revealing The Quality Of Movement: A Meta-Analysis Review To Quantify The Thresholds To Pathological Variability During Standing And Walking, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Neuromotor processes are inherently noisy, which results in variability during movement and fluctu-ations in motor control. Although controversial, low levels of variability are traditionally considered healthy, while increased levels are thought to be pathological. This systematic review and meta-analysisof the literature investigates the thresholds between healthy and pathological task variability.

After examining 13,195 publications, 109 studies were included. Results from over 3000 healthy sub-jects and 2775 patients revealed an overall positive effect size of pathology on variability of 0.59 forwalking and 0.80 for sway. For the coefficient of variation of stride time (ST) and sway area (SA), upperthresholds of 2.6% …

The Mysteries Of Your Blood, Alexandra J. Mauer

BU Well

Did you know that your blood type can be useful for determining disease susceptibility and even creating a diet that works best for your personal metabolism? The Mysteries of your Blood is an article that delves into the science behind the ABO blood types and explains why your body can handle certain foods, stress, and illness differently than someone with a different blood type. It proposes a new, perplexing way to determine how to avoid certain health problems while at the same time offering suggestions of what to eat or, rather, what to avoid eating.

The worst yellow fever epidemic in Angola since 1986 is rapidly spreading, including the capital, Luanda. In Angola, the epidemic began in December 2015 and the laboratory-confirmed outbreak was reported to the World Health Organization (WHO) on January 21, 2016. Angola has had 2023 suspected cases and 258 deaths as of April 26, 2016. China, the Democratic Republic of Congo, and Kenya also have reported cases arising from infected travelers from Angola. Namibia and Zambia also share a long border with Angola, with considerable population movement between the countries. Similar to other recent epidemics, quick and effective action to stop …

Expression And Function Of Inflammation-Associated Micrornas In Traumatic Brain Injury, Emily Harrison

Theses & Dissertations

MicroRNAs (miRNAs) are important regulators of gene expression. Many neurological diseases, including traumatic brain injury alter expression of miRNAs in the brain. However, the function of these molecules in the context of TBI is largely unknown. Here we report multiple potential roles for miRNAs in TBI, some of which extend beyond the traditional model of post-transcriptional regulation, highlighting that these RNA molecules may have broader implications for the neurobiology of disease. We found that miR-155 plays an essential role in interferon expression after CCI and that miR-155 contributes to TBI induced anxiety, potentially through regulation of interferons. Expression of miR-155 …

Evaluation Of Interleukin-3 In Blood-Stage Immunity Against Murine Malaria Plasmodium Yoelii, Haley E. Davis

Senior Honors Projects, 2010-2019

Malaria is a mosquito-borne infection caused by the parasitic protozoan Plasmodium. This disease infects over 200-300 million people and causes nearly 400,000 deaths every year. Our laboratory previously examined malarial infection caused by Plasmodium berghei NK65, a lethal rodent strain that induces symptoms similar to those observed in humans. The results of this previous study indicated that the hematopoietic growth factor and immunoregulatory cytokine interleukin-3 (IL-3) suppressed protective immunity against infection with P. berghei NK65. However, the extent to which IL-3 contributes to host defense against blood-stage malaria infection caused by other Plasmodium species remains to be determined. In …

Role Of Interleukin-3 In An Experimental Model Of Mouse Cerebral Malaria Caused By Plasmodium Berghei Anka, Brendon R. Perry

Senior Honors Projects, 2010-2019

Malaria is a life-threatening mosquito-borne disease caused by parasites of the genus Plasmodium, with about 200 million new cases reported each year. In rodent models of malaria, a variety of immune proteins called cytokines have been noted to either promote or suppress protective immunity. While the cytokine interleukin-3 (IL-3) clearly promotes host defense against some intestinal nematode parasites, few studies have reported a similar function for IL-3 in the pathophysiology of malaria. In this study, we investigated the role of IL-3 in a mouse model of cerebral malaria caused by Plasmodium berghei ANKA. We infected wild-type (WT) and IL-3 …

Recurrent Mutations Of T-Cell Receptor And Co-Stimulatory Signaling Proteins In Peripheral T-Cell Lymphomas, Joseph Rohr

Theses & Dissertations

Peripheral T-cell lymphomas (PTCLs) comprise a heterogeneous group of mature T-cell neoplasms with a poor prognosis. Recently, mutations in TET2 and other epigenetic modifiers as well as RHOA have been identified in these diseases, particularly in angioimmunoblastic T-cell lymphoma (AITL). CD28 is the major co-stimulatory receptor in T-cells which, upon binding ligand, induces sustained T-cell proliferation and cytokine production when combined with T-cell receptor stimulation, through many signaling molecules including VAV1. This thesis identifies recurrent mutations in CD28 in PTCLs, as well as mutations in VAV1. Two residues of CD28 – D124 and T195 – were recurrently mutated in 11.3% …

Genetic Predisposition And M1 Macrophage Polarization Created By Elastin-Derived Peptides Drive Abdominal Aortic Aneurysm Formation, Matthew A. Dale

Theses & Dissertations

Abdominal aortic aneurysm (AAA) is a dynamic vascular disease characterized by inflammatory cell invasion and extracellular matrix (ECM) degradation. Evidence has demonstrated a profound influence of genetic background on AAA formation. The work presented herein discusses two studies: the first demonstrates how genetic components can enhance the susceptibility to AAA formation and the second demonstrates how ECM degradation enhances AAA progression by influencing inflammatory cell phenotypes. An understanding of the pathways involved in AAA pathogenesis can help not only to identify potential patients at risk of AAA development, a heritable disease in which the incriminating component has yet to be …

The Effects Of Implementing Best Practice On Clostridium Difficile Infection Treatment, Melissa A. Craig

Evidence-Based Practice Project Reports

For many years the number of Clostridium difficile infections (CDI) has steadily risen. This common cause of antibiotic-associated diarrhea can have variable clinical presentations ranging from mild diarrhea to severe cases complicated by the development of pseudomembranous colitis, electrolyte abnormalities, dehydration, sepsis, and even death. The resistant nature of the spores produced by the bacteria and the emergence of hypervirulent strains have made treatment challenging. Previous studies have demonstrated clinician non-adherence to CDI clinical treatment guidelines may result in poor patient outcomes. This evidence-based practice project was implemented at a 311 bed academic medical center in the Midwest. The project …

The Effect Of Heart Failure Education On Knowledge And Readmission, Sara A. Golden

Evidence-Based Practice Project Reports

Heart Failure (HF) is a chronic progressive disease affecting over 5 million individuals with an expected increase in incidence as the population ages (Yehle & Plake, 2010). The costs associated with managing HF continue to increase and the Centers for Medicare and Medicaid Services (CMS) have attempted to identify ways to improve patient management of HF to reduce the revolving door of hospital readmissions and decrease expenditures. According to 2006 data, as many as one fourth of the Medicare beneficiaries discharged from acute care to skilled nursing facilities (SNF) were readmitted to the hospital within 30 days and the majority …

Routine Screening For Abdominal Aortic Aneurysm: Is It For Everyone?, Catherine E. Nowak

Physician Assistant Capstones, 2016 to 2019

Objective: Determine whether routine abdominal ultrasound screening in all men ages 65 and over, not just those who are symptomatic or at risk, would be beneficial in reducing the mortality rate from abdominal aortic aneurysms (AAA). Design: Systematic literature review. Methods: The clinical question investigated is whether routine ultrasound screening of AAA for men over age 65 reduces AAA-related mortality as compared to not routinely screening. Searches were done through PubMed using the keywords: screening, abdominal aortic aneurysm, reduce, and mortality. Citations used by the USPSTF AAA screening guidelines were also added to the literature search. In PubMed, further limitations …

National Institute Of Health Stroke Scale (Nihss) Inter-Rater Reliability And Confidence Among Nihss Certified Nurses: Implementation Of A Standardized Patient Simulation, Kelly J. Trieglaff

Evidence-Based Practice Project Reports

The National Institute of Health Stroke Scale (NIHSS) is the most common stroke assessment used by nurses. Nurses certified on the NIHSS do not consistently demonstrate inter-rater reliability nor are they confident when assessing stroke patients using the tool (Josephson, Hills, Johnston, 2006). This EBP project evaluated a standardized patient simulation for maintaining inter-rater reliability and confidence in NIHSS certified nurses. A literature review showed that a decrease in inter-rater reliability occurs within four weeks to three months of NIHSS certification. A single cohort of intensive care nurses and emergency department nurses used the NIHSS tool in a standardized patient …

IAPP is an amyloid protein that misfolds, causing toxic aggregation in the pancreas of Type II Diabetes patients. In this study, three metal cations (KCl, CaCl2, and CuCl2) are tested in Thioflavin T assays and atomic force microscopy (AFM) to see if they inhibit the aggregation of IAPP.

Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty

Graduate School of Biomedical Sciences Theses and Dissertations

Aerobic vaginitis (AV) is a more recently defined infection that involves aerobic pathogenic bacteria that replace the normal flora of the vaginal tract. It is commonly mistaken for other vaginal infections, such as bacterial vaginosis (BV), because they share many common symptoms. AV leads to complications during pregnancy, such as premature delivery and amnion infection, and is diagnosed by indications that range from vaginal discharge to inflammation. Because this infection is difficult to diagnose differentially from other vaginal infections, it is important to determine what pathogens are involved in AV so that we may have the ability to detect them. …

Exploring The Effect Of Novel Small Molecules On Oligodendrocyte Precursor Proliferation, Sagune Sakya

University Scholar Projects

Gliomas, a type of brain tumor, can be difficult to treat and have a poor survival rate. One pathway that leads to glioma formation is excessive signaling by platelet derived growth factors (PDGF) through PDGF receptor α (PDGFRα). Through this research, I found that novel compounds that downregulate PDGFRα decrease proliferation of Oli-neu cells, an oligodendrocyte precursor cell model, and identified signaling pathways through which these compounds may exert their effect. Further investigation may identify targets for development of glioma treatments.
