Case Report: Cavitary Pneumonia In A 28 Year Old Male, Dan Zaayenga, Katelyn Courtney

Rowan-Virtua Research Day

Cavitary pneumonia can be caused by several different mechanisms. Such causes include suppurative necrosis (pyogenic lung abscess), caseous necrosis (tuberculosis), ischemic necrosis (pulmonary infarction) cystic dilatation of lung structures (ball value obstruction and Pneumocystis pneumonia) as well as malignant processes. Causes are subject to both environmental factors and host susceptibility. The most common cause of infectious process is tuberculosis with its propensity to cause extensive caseous necrosis. The potential for secondary infection after an individual develops a cavitary pneumonia is also great as it provides a shelter for various pathogens the flourish in an environment otherwise usually well-guarded by host …

Laboratory Evaluation Of An Enzyme Immunoassay To Detect Coccidioides Galactomannan Antigens In Serum Samples, Anneliese Ahrens

Biological Sciences Undergraduate Honors Theses

Introduction: Coccidioidomycosis (cocci) is an infection caused by fungal pathogens in soil of dry and arid regions in the Southwestern states of the United States. The disease can present itself anywhere in the body, but usually is found in the lungs. The symptoms are very similar to the symptoms of a bacterial or viral respiratory infection, which is one of the reasons it is commonly misdiagnosed or left untreated. The CDC reports cases to have increased 143% from 2014 to 2019, with a mortality rate of 200 deaths per year, however this is likely underreported because of the inadequacies of …

The Diagnostic Odyssey Of Hypermobile Eds Patients: Diagnosis, Clinical Expectations, And Psychosocial Concerns, Madeline Alpar

Dissertations and Theses (Open Access)

Background: Ehlers-Danlos syndrome (EDS) is a highly variable, heritable connective tissue disorder. Hypermobile EDS (hEDS) is the most common subtype of EDS and has no identifiable underlying genetic etiology. Patients with clinical features of hEDS face a long diagnostic odyssey due to lack of genetic testing and wide clinical heterogeneity. Additionally, recent research has shown that genetic institutions limit evaluations for suspected hEDS, adding another barrier to care.

Methods: We developed an online patient survey to explore the diagnostic odyssey of hEDS for those who were diagnosed with or suspicious for hEDS. This survey included sections on demographics, diagnostic information …

Impact Of Personal, Familial, And Socioeconomic Factors On The Return Of Remotely Collected Samples For Genetic Testing, Jordan Zeiger

Dissertations and Theses (Open Access)

There are a multitude of barriers known to impact access to medical care in the United States. COVID-19 has changed and compounded these barriers and led to a shift in the setting of the genetic counseling (GC) appointment, and in sample types used for genetic testing, specifically with use of telemedicine and remotely collected saliva kits. Previous studies have described lack of patient follow-through in returning these kits. Though the understanding of barriers to medical care, including access to genetics services, is well described, there is little in the literature for how these barriers impact the return of remotely collected …

Outpatient Breast Cancer Screening Documentation, Christoffer A. Amdahl, Jeremy Smith

North Texas GME Research Forum 2023

Introduction: Over 264,000 cases of breast cancer are diagnosed annually within the United States, with 99% of them being in women. Regarding prevention of this terrible disease, early detection of such cancers through screening mammography has up to a 20% reduction in breast cancer mortality. Therefore, the USPSTF recommends screening of women who are 50-74 years of age via mammography at average risk of breast cancer every two years. The goal of this study was to measure, track, and increase compliance with these screening recommendations within the Medical City resident clinics.

Method: Family medicine residents working were presented with a …

Bioinformatic Analysis Of Mirna Mechanisms In Circadian Rhythm Using A Zebrafish (Danio Rerio) Model, Layton F. Coursey

Honors College Theses

MicroRNAs are noncoding RNAs found in cells and the bloodstream, which help to maintain proper protein production and overall gene expression1. Typically, microRNAs bind to messenger RNA (mRNA) in the cell cytoplasm, acting as post-transcriptional regulators, and either degrade or repress mRNA2. Due to microRNAs playing a vital role in gene expression by repressing protein production of target genes, if they are underexpressed then the protein it regulates could be overexpressed as a result.

miRNAs have the potential to be biomarkers for numerous neurodegenerative diseases. Neurodegeneration can be seen in many forms such as Dementia, Alzheimer’s (AD), Huntington’s Disease (HD), …

Yurista, Jaume Coll-Font, Shi Chen, Robert A. Eder, Anna N. Foster, Khoi D. Nguyen, Peter Caravan, Eric M. Gale, Christopher Nguyen

School of Medicine Faculty Publications

BACKGROUND: Late gadolinium enhancement cardiac magnetic resonance imaging is an effective and reproducible method for characterizing myocardial infarction. However, gadolinium-based contrast agents are contraindicated in patients with acute and chronic renal insufficiency. In addition, several recent studies have noted tissue deposition of free gadolinium in patients who have undergone serial contrast-enhanced magnetic resonance imaging. There is a clinical need for alternative forms of magnetic resonance imaging contrast agents that are acceptable in the setting of renal insufficiency. METHODS AND RESULTS: Three days after 80 minutes of ischemia/reperfusion of the left anterior descending coronary artery, cardiac magnetic resonance imaging was performed …
