Bridging The Gap In Primary Care Of Inflammatory Bowel Disease (Ibd) Patients, Deanna Dial

Dissertations

Abstract

Problem. Patients in rural or medically underserved areas (MUAs) with inflammatory bowel disease (IBD) have limited access to primary care preventative services, making them even less likely to obtain preventative care, placing them at even greater risk for adverse health outcomes.

Methods. A two-phase retrospective chart review utilizing a convenience sample of patients diagnosed with IBD from a privately-owned gastroenterology office to evaluate the effectiveness of increasing preventative screenings for IBD patients. The first review included 53 patients seen from January to April 2019. A preventative screening

evaluation tool (PSET) was developed based on literature recommendations, including the American …


Evaluation Of Mcgeer Criteria For Uti Determination In A Nursing Home, Julie Rehagen Jul 2020

Evaluation Of Mcgeer Criteria For Uti Determination In A Nursing Home, Julie Rehagen

Dissertations

Problem: Urinary tract infection (UTI) is one of the most complex and challenging medical diagnoses to make in the long-term care (LTC) population. The unnecessary treatment of a UTI can increase cost of care and the likelihood of multi-drug resistant organisms.

Methods: The McGeer criteria which focuses on UTI in the LTC population was utilized to complete a quality improvement initiative. A descriptive cohort project utilizing retrospective and prospective data was completed to determine if an implemented McGeer criteria protocol improved the avoidable treatment of asymptomatic bacteriuria (ASB).

Results: Before implementation of the protocol, 62.5% of residents were unnecessarily treated …


Measuring Movement And Social Contact With Smartphone Data: A Real-Time Application To Covid-19, Victor Couture, Jonathan L. Dingel, Allison Green, Jessie Handbury, Kevin R. Williams Jul 2020

Measuring Movement And Social Contact With Smartphone Data: A Real-Time Application To Covid-19, Victor Couture, Jonathan L. Dingel, Allison Green, Jessie Handbury, Kevin R. Williams

Cowles Foundation Discussion Papers

Tracking human activity in real time and at fine spatial scale is particularly valuable during episodes such as the COVID-19 pandemic. In this paper, we discuss the suitability of smartphone data for quantifying movement and social contact. We show that these data cover broad sections of the US population and exhibit movement patterns similar to conventional survey data. We develop and make publicly available a location exposure index that summarizes county-to-county movements and a device exposure index that quantifies social contact within venues. We use these indices to document how pandemic-induced reductions in activity vary across people and places.

A Study Of Covid-19 Mortality Under Varying Patient Frailty, Alison N. Sifuentes Jul 2020

A Study Of Covid-19 Mortality Under Varying Patient Frailty, Alison N. Sifuentes

Theses and Dissertations

Modeled the spread and mortality of COVID-19 throughout the city of Chicago. By incorporating group frailty into a classic SEIR infectious disease model, we were able to differentiate the population of Chicago by their response to COVID-19. Three age groups with different COVID-19-induced death rates were examined, and the model sought to showcase the multiplicative deviation of each age group death rate from the average disease-induced death rate. This adjustment for different death rates among age groups accounted for heterogeneity within the population, and sought to introduce a more accurate manner for modeling the spread of infectious diseases.

A Study On Ecological Distribution Of And Selected Gene Expression In Amblyomma Americanum: An Insight Into The Alpha-Galactose Allergy Caused By Tick Bites, Leah Cuthill

Electronic Theses & Dissertations

Ticks transmit a wide variety of pathogens including viruses, bacteria, protozoa, and helminthes to vertebrates. Their life cycle depends on blood meals from various hosts as well as on environmental conditions such as the temperature and habitat type. A newly recognized allergic disease has been identified and is characterized by a delayed reaction following the consumption of some mammalian meats. The allergy often results in life threatening reactions such as anaphylaxis, hives, and breathing problems 3-6 hours after the consumption of mammalian meat. Not everyone develops the allergy when they are bitten by a lone star tick, and the cause …

Immune checkpoint inhibitors (ICI) have shown positive results in patients with hepatocellular carcinoma (HCC). As liver function contributes to prognosis, its precise assessment is necessary for the safe prescribing and clinical development of ICI in HCC. We tested the accuracy of the albumin-bilirubin (ALBI) grade as an alternative prognostic biomarker to the Child-Turcotte-Pugh (CTP). In a prospectively maintained multi-centre dataset of HCC patients, we assessed safety and efficacy of ICI across varying levels of liver dysfunction described by CTP (A to C) and ALBI grade and evaluated uni- and multi-variable predictors of overall (OS) and post-immunotherapy survival (PIOS). We studied …


Cholera In Present-Day Haiti: Interpretations Of And Responses To A Contemporary Enemy, Melissa Frick Jul 2020

Cholera In Present-Day Haiti: Interpretations Of And Responses To A Contemporary Enemy, Melissa Frick

Swarthmore Undergraduate History Journal

Note: In lieu of an abstract, this is the article's first paragraph.

"In his introduction to Epidemics and Ideas, Paul Slack calls to revive the study of social history of epidemics, wanting to show how societies cope with, react to, and interpret crises of disease. He reviews historian Richard Evans’ notion of the “common dramaturgy” to all epidemics, which states that human society responds to mass infection through an inherent response mechanism. Disease presents common dilemmas - including decisions on how the disease is transmitted, whom it infects, who is to blame, and incites common responses. Furthermore, Slack suggests that …

Swarthmore Undergraduate History Journal

Note: In lieu of an abstract, this is the article's first paragraph.

"By 1992, the AIDS epidemic in the United States had reached seemingly catastrophic proportions. Over ten years after the first published report of AIDS-related lung infection, the number of AIDS cases in the United States far exceeded 100,000. It would be four years until the FDA approval of the first protease inhibitor. Over ten thousand women had been diagnosed with the disease, and experts expected over ninety thousand more were already infected. The disease, lacking effective treatment, increasingly struck women and people of color in the early 1990s; …


Theatrical Illness: Tuberculosis And Hiv As Presented By "La Boheme" And "Rent", Jessica Downing Jul 2020

Theatrical Illness: Tuberculosis And Hiv As Presented By "La Boheme" And "Rent", Jessica Downing

Swarthmore Undergraduate History Journal

Note: In lieu of an abstract, this is the article's first paragraph.

"The musical Rent made its Broadway debut on January 25, 1996, a century after the opening performance of the opera, La Boheme. This correlation was a coincidence, though Rent draws significantly on the story of La Boheme, to the extent that a New York Times reviewer deemed it a "contemporary answer to Puccini's 'Boheme."' Each of these productions presents the troubles and tragedies of the bohemian lifestyle in a specific time and place-La Boheme in Paris during the 1830s and Rent in New York City during 1989. Disease, …


"Loathsome And Dangerous": Health Screening In A Globalized World, Gabriel Hearn-Desautels Jul 2020

"Loathsome And Dangerous": Health Screening In A Globalized World, Gabriel Hearn-Desautels

Swarthmore Undergraduate History Journal

Note: In lieu of an abstract, this is the article's first paragraph.

"As the world has become steadily more interdependent over the last century, disease has been able to spread with increasing ease. As a consequence of this new danger, the international community has changed the way that it understands contagion, and public health has taken on new roles and new meanings around the world. I argue that the globalization of public health and the relatively new perception of diseases as “global” threats have dramatically altered practices of health screening, both at the border and beyond. Above all, these changes …

Pathology, East Africa

Background: Due to a lack of reliable reference intervals (RIs) for Kenya, we set out to determine RIs for 40 common chemistry and immunoassay tests as part of the IFCC global RI project.

Methods: Apparently healthy adults aged 18–65 years were recruited according to a harmonized protocol and samples analyzed using Beckman-Coulter analyzers. Value assigned serum panels were measured to standardize chemistry results. The need for partitioning reference values by sex and age was based on between-subgroup differences expressed as standard deviation ratio (SDR) or bias in lower or upper limits (LLs and ULs) of the RI. RIs …

Disease Salience Effects On Desire For Affiliation With In-Group And Out-Group Members: Cognitive And Affective Mediators, Murray Millar, Andrea Fink-Armold, Aileen Lovitt

Psychology Faculty Research

This study tested the hypothesis that threats related to infectious diseases would make persons less willing to affiliate with out-groups and that feelings of disgust and beliefs about the out-group members would mediate this effect. To test this hypothesis, American participants of European descent were presented with either a disease threat or control threat. Then they were shown a photograph of someone of the same race or different race. Participants were asked to indicate whether they would avoid the target person and to state their emotional and cognitive responses to the person. As predicted, disease salience decreased the desire to …

Faculty Research, Scholarly, and Creative Activity

In the Gulf of Mexico, especially along the southwest Florida coast, blooms of the dinoflagellate Karenia brevis are a coastal natural hazard. The organism produces a potent class of toxins, known as brevetoxins, which are released following cell lysis into ocean or estuarine waters or, upon aerosolization, into the atmosphere. When exposed to sufficient levels of brevetoxins, humans may suffer from respiratory, gastrointestinal, or neurological illnesses. The hazard has been exacerbated by the geometric growth of human populations, including both residents and tourists, along Florida’s southwest coast. Impacts to marine organisms or ecosystems also may occur, such as fish kills …

Pathophysiology Of Hyperkalemia Presenting As Brugada Pattern On Electrocardiogram (Ecg), Benjamin Doty, Elaine Kim, Jeremiah T. Phelps, Peter Akpunonu Jul 2020

Pathophysiology Of Hyperkalemia Presenting As Brugada Pattern On Electrocardiogram (Ecg), Benjamin Doty, Elaine Kim, Jeremiah T. Phelps, Peter Akpunonu

Emergency Medicine Faculty Publications

BACKGROUND Brugada phenocopies (BrP) are clinical and electrocardiographic (ECG) entities elicited by reversible medical conditions speculated to have pathogenesis rooted in ion current imbalances or conduction delays within the myocardial wall. During an inciting pathologic condition, it produces ECG patterns identical to those of congenitally-acquired Brugada syndrome and subsequently returns to normal ECG patterns upon resolution of the medical condition. This case report describes a 26-year-old man presenting to the Emergency Department (ED) for suspected heroin overdose with a rare ECG consistent with BrP secondary to acute hyperkalemia.

CASE REPORT A 26-year-old man with a history of substance abuse and …

United States Department of Agriculture Wildlife Services: Staff Publications

Research on the ecology of fear has highlighted the importance of perceived risk from predators and humans in shaping animal behavior and physiology, with potential demographic and ecosystem-wide consequences. Despite recent conceptual advances and potential management implications of the ecology of fear, theory and conservation practices have rarely been linked. Many challenges in animal conservation may be alleviated by actively harnessing or compensating for risk perception and risk avoidance behavior in wild animal populations. Integration of the ecology of fear into conservation and management practice can contribute to the recovery of threatened populations, human–wildlife conflict mitigation, invasive species management, maintenance …

Coeliac Disease Pathogenesis: The Uncertainties Of A Well-Known Immune Mediated Disorder, Greg Byrne, Margaret Dunne, Con Feighery, Fernando Chirdo

Articles

Coeliac disease is a common small bowel enteropathy arising in genetically predisposed individuals and caused by ingestion of gluten in the diet. Great advances have been made in understanding the role of the adaptive immune system in response to gluten peptides. Despite detailed knowledge of these adaptive immune mechanisms, the complete series of pathogenic events responsible for development of the tissue lesion remains less certain. This review contributes to the field by discussing additional mechanisms which may also contribute to pathogenesis. These include the production of cytokines such as interleukin-15 by intestinal epithelial cells and local antigen presenting cells as …

Edwardsiella Ictaluri Is Capable Of Persisting In Channel Catfish By Evading Host T Cell And Cell Death Responses, Elizabeth Watts Griggs

LSU Doctoral Dissertations

Edwardsiella ictaluri is a gram-negative bacterium of the family Enterobacteriaceae that infects and causes enteric septicemia (ESC) of channel catfish (Ictalurus punctatus), a fatal disease costing the catfish industry millions of dollars in losses each year. Edwardsiella. ictaluri is capable of replicating in catfish head-kidney-derived-macrophages (HKDM), and like many other gram-negative bacteria, E. ictaluri encodes a Type III Secretion System (T3SS) that is required for virulence and intracellular replication. In the case of E. ictaluri, the T3SS translocates effectors from the Edwardsiella containing vacuole (ECV) through the bacterial cell wall and the vacuolar membrane directly to the …
