Real-world evidence regarding the value of integrating genomic profiling (GP) in managing cancer of unknown primary (CUP) is limited. We assessed this clinical utility using a prospective trial of 158 patients with CUP (October 2016-September 2019) who underwent GP using next-generation sequencing designed to identify genomic alterations (GAs). Only 61 (38.6%) patients had sufficient tissue for successful profiling. GAs were seen in 55 (90.2%) patients of which GAs with US Food and Drug Administration-approved genomically matched therapy were seen in 25 (40.9%) patients. A change in therapy was recommended and implemented (primary endpoint of the study) in 16 (10.1%) and …

The Association Of Hobbies And Leisure Activities With Physician Burnout And Disengagement, Yan Li, Cindy Y. Lai, Bill Friedrich, Chenxing Liu, Joel H. Popkin

Journal of Wellness

Introduction: Burnout among physicians is a worldwide burden. While many causes of physician stress have been reported, we have found few quantitative studies of associations between burnout and participation in hobbies and interests outside of medicine. Our objective was to determine if health care professional burnout/disengagement could be mitigated by incorporating leisure interests and to characterize which specific interests, if any, are most significantly related.

Methods: We conducted an online survey of 2,563 US-based physicians and 512 residents/fellows and queried their participation in a list of 117 individual hobbies, which we then further categorized into three perceived levels …

Terror Management And The News: An Exploration Into The Effects Of Framing On Mortality Salience, Peter Montwill

Masters Theses, 2020-current

The present study explores the link between Terror Management Theory and the use of its principles within news media. Political news media in the digital age undergoes a variety of framing effects, more specifically episodic and thematic frames of stories. To induce mortality salience, college-aged participants were presented with stories framed from the perspective of an individual’s experience or a general theme of experiences regarding the controversial pro-life topic and a non-controversial hiking topic. These stories are presented in the style of Instagram posts to mirror how college-aged people consume news media. The stories also contain wording designed to induce …

Faculty, Staff and Student Publications

Erdheim-Chester disease (ECD) and Rosai-Dorfman disease (RDD) are rare non-Langerhans cell histiocytoses (non-LCHs), for which therapeutic options are limited. MAPK pathway activation through BRAFV600E mutation or other genomic alterations is a histiocytosis hallmark and correlates with a favorable response to BRAF inhibitors and the MEK inhibitor cobimetinib. However, there has been no systematic evaluation of alternative MEK inhibitors. To assess the efficacy and safety of the MEK inhibitor trametinib, we retrospectively analyzed the outcomes of 26 adult patients (17 with ECD, 5 with ECD/RDD, 3 with RDD, and 1 with ECD/LCH) treated with orally administered trametinib at 4 major US …

Phylogenetic Inference From Single-Cell Rna-Seq Data, Xuan Liu, Jason I Griffiths, Isaac Bishara, Jiayi Liu, Andrea H Bild, Jeffrey T Chang

Faculty, Staff and Student Publications

Tumors are comprised of subpopulations of cancer cells that harbor distinct genetic profiles and phenotypes that evolve over time and during treatment. By reconstructing the course of cancer evolution, we can understand the acquisition of the malignant properties that drive tumor progression. Unfortunately, recovering the evolutionary relationships of individual cancer cells linked to their phenotypes remains a difficult challenge. To address this need, we have developed PhylinSic, a method that reconstructs the phylogenetic relationships among cells linked to their gene expression profiles from single cell RNA-sequencing (scRNA-Seq) data. This method calls nucleotide bases using a probabilistic smoothing approach and then …

Evaluation Of The Virulence Potential Of Avian Pathogenic Escherichia Coli Isolated From Broiler Breeders With Colibacillosis In Mississippi, Jiddu Joseph

Theses and Dissertations

Avian pathogenic Escherichia coli (APEC) is a bacterium that is responsible for colibacillosis in birds. However, information about broiler breeder APEC isolates is limited, but the data is critical due to the transfer of this bacteria down the production pyramid to progenies resulting in high mortality. Therefore, we evaluated the phenotypic virulence characteristics of 28 isolates using embryo lethality and day-old chick challenge assays. Also, the in vitro adhesion and invasion potential of selected nine isolates were identified. Results showed more than 1/3^rd of the isolates were highly virulent and the virulence increased as the number of virulence-associated genes …

Obesity, in which the functional importance of small nucleolar RNAs (snoRNAs) remains elusive, correlates with risk for many cancer types. Here, we identify that the serum copies of adipocyte-expressed SNORD46 correlate with body mass index (BMI), and serum SNORD46 antagonizes interleukin-15 (IL-15) signaling. Mechanically, SNORD46 binds IL-15 via G11, and G11A (a mutation that significantly enhances binding affinity) knockin drives obesity in mice. Functionally, SNORD46 blocks IL-15-induced, FER kinase-dependent phosphorylation of platelet glycoprotein 4 (CD36) and monoglyceride lipase (MGLL) in adipocytes, leading to inhibited lipolysis and browning. In natural killer (NK) cells, SNORD46 suppresses the IL-15-dependent autophagy, leading to reduced …

Faculty, Staff and Students Publications

BACKGROUND: Bronchopulmonary dysplasia (BPD) is characterized by an arrest in lung development and is a leading cause of morbidity in premature neonates. It has been well documented that BPD disproportionally affects males compared to females, but the molecular mechanisms behind this sex-dependent bias remain unclear. Female mice show greater preservation of alveolarization and angiogenesis when exposed to hyperoxia, accompanied by increased miR-30a expression. In this investigation, we tested the hypothesis that loss of miR-30a would result in male and female mice experiencing similar impairments in alveolarization and angiogenesis under hyperoxic conditions.

METHODS: Wild-type and miR-30a−/− neonatal mice were exposed …

Loaded Lipid Emulsified Volatile Anesthetics In Canine Primary Hepatocytes, Patricia De Carvalho Ibrahim Obeid

Theses and Dissertations

In the 19th century, halothane hepatitis became a sensitive and well-known subject in human anesthesiology due to the production of a noxious metabolite further discovered, trifluoroacetic acid. Subsequently, isoflurane, enflurane, and desflurane were also investigated for potentially causing hepatitis through the same metabolite. Sevoflurane, however, does not generate trifluoroacetic acid and is quickly conjugated and excreted.

For more than four decades these anesthetics have been experimentally developed for intravenous injection by having added either a lipid or fluorocarbon-based carrier to produce general anesthesia with less drug and faster onset of action. The use of intravenous emulsified halogenated anesthetics as an …

Comparison Of Aging Techniques In Wild Bottlenose Dolphins (Tursiops Truncatus) Of Unknown Age From The Mississippi Sound., Christa Elizabeth Barrett

Theses and Dissertations

Age determination of bottlenose dolphins (Tursiops truncatus) is a critical tool in understanding their health. There are many methods of aging dolphins including morphometrics, counting growth layer groups (GLGs) of teeth, comparing dentin to pulp cavity ratio on dental radiographs, analysis of the pectoral flipper radiographs, and epigenetic testing. The most common method for aging toothed cetaceans is the counting of GLGs in the teeth. Since there are many challenges associated with aging dolphins based on the counting of GLGs, a processing technique that results in better resolution of GLGs is needed. This is a two-part study that …

The Effect Of An Aiming Device On The Accuracy Of Humeral Transcondylar Screw Placement, Katherine Neal

Theses and Dissertations

Canine cadaveric forelimbs (136) were randomly assigned to either treatment (aiming device) or control (fluoroscopic-guided) groups, and to either diplomate or resident for humeral transcondylar screw placement. Each limb underwent a transcondylar humeral screw placement from a lateral to medial direction. Digital radiography was used to evaluate screw trajectory, measured as deviation from the epicondylar line, and eccentricity on the humeral condyle. Procedure time, difference in outcome based on experience level, and complications were recorded. In the right limb, screw trajectory with the aiming device was decreased compared to fluoroscopy. There was no difference of accuracy between leg laterality with …

Vertical Federated Learning Using Autoencoders With Applications In Electrocardiograms, Wesley William Chorney

Theses and Dissertations

Federated learning is a framework in machine learning that allows for training a model while maintaining data privacy. Moreover, it allows clients with their own data to collaborate in order to build a stronger, shared model. Federated learning is of particular interest to healthcare data, since it is of the utmost importance to respect patient privacy while still building useful diagnostic tools. However, healthcare data can be complicated — data format might differ across providers, leading to unexpected inputs and incompatibility between different providers. For example, electrocardiograms might differ in sampling rate or number of leads used, meaning that a …
