Persistent Oropharyngeal Dysphagia Caused By Systemic Light Chain Amyloidosis Despite Hematologic Response: A Case Report, Haw-Wen Jeng, Tyng-Guey Wang, Kuo-Chang Wei

Rehabilitation Practice and Science

We report a case of a 44-year-old woman who developed progressive dysphagia and shoulder stiffness, ultimately leading to a diagnosis of multiple myeloma (MM) with systemic light-chain (AL) amyloidosis. Despite intensive systemic therapy for MM with good serological response and nine months of comprehensive swallowing rehabilitation, her tongue mobility remained severely restricted, with only minimal improvement in laryngeal elevation. Videofluoroscopic swallowing study (VFSS) confirmed poor tongue control, reduced laryngeal elevation, and penetration of thin liquids. She ultimately passed away despite hematologic control. This case underscores the profound impact of amyloid deposition on swallowing function, even in the context of medically …

Correlates Of Gacha Gaming, Minh Quang Nguyen

Graduate Theses/Dissertations

The purpose of this study was to explore the relationship between impulsive measures, income spending on gaming, and delayed discounting in a Gatha player sample. Two model approaches were employed: (1) a mediation model approach predicting delayed discounting with age and education level as mediators and (2) a multiple regression model predicting delayed discounting. Although the proposed models were exploratory, it was the contention of the author that these analyses would result in a better understanding of delayed discounting in Gacha gaming. Both age and education level were not correlated with the dependent variable (spending ratio), therefore the mediation model …

The Effect Of Hypochlorous Acid On Cultured Osteoblast And Escherichia Coli, Cristina Flaquer Fusté

Graduate Theses/Dissertations

Hypochlorous acid (HOCl), a naturally occurring compound in neutrophils, has been used as an antimicrobial in wound treatment. Osteoblasts, bone-forming cells, within the bone tissue play a large role in bone fracture healing. Orthopedic infections are challenging to treat and highly morbid, including surgical site infection of arthroplasty procedures or infection in the setting of compound fractures. HOCl is being considered as a surgical antiseptic to decrease infections in orthopedic surgical procedures. This study therefore seeks to determine the effects of HOCl on osteoblasts and E. coli. Cultured osteoblasts were incubated with varying concentrations of HOCl to examine osteoblast …

Characterization Of The Overexpression Of Reca Homologs Rad51 And Dmc1 In Tetrahymena Thermophila, Jianna M. Cox

Graduate Theses/Dissertations

RecA homologs, Dmc1 and Rad51, work to repair DNA double-strand breaks (DSBs) within the cell through the recombination of homologous sections of DNA. Dmc1 works to repair programmed DSBs through meiotic recombination, while Rad51 functions to repair both meiotic and non-meiotic DSBs, the latter repaired through the process of homologous recombination repair (HHR). Chemotherapeutics, exogenous agents, work to form DSBs in cancer cells, attempting to inhibit the cell’s growth. A hyper recombinant phenotype is often seen in cancer cells due to the overexpression of RAD51, leading to drug resistance, the persistence of cancers, and an overall poor patient outcome. …

Incidence Of Bleeding And Performance Of The Precise-Dapt Score In Predicting Bleeding In Patients On Dual Antiplatelet Therapy After Treatment For Acute Coronary Syndrome In Kenya, Peter Mugo, Jeilan Mohamed, Miriam Msunza, James Orwa, Mzee Ngunga

Internal Medicine, East Africa

Introduction: Dual Antiplatelet Therapy (DAPT) plays an important role in the secondary prevention of ischemic events after treatment for acute coronary syndrome (ACS). The long-term use of DAPT is associated with an increased risk of bleeding, which affects morbidity and mortality. Risk stratification scores have been developed to predict this risk and provide a balance against the risk of ischemic events. The aim of this study was to determine the incidence of bleeding in a cohort of patients in Kenya on DAPT and assess the performance of the PRECISE-DAPT Score in predicting the risk of bleeding.

Methods: This was a …

The Sky’S The Limit: Improving Satellite Imagery Data Literacy To Address Noncommunicable Diseases, M. Courtney Hughes, Elizabeth J. Folkmann

Faculty Articles, Papers, and Other Scholarship

Low-and middle-income countries experience 77% of the world’s premature deaths caused by non- communicable diseases, and their underlying health determinant data are often scarce and inaccurate. Im- proving satellite imagery data literacy worldwide is an integral step toward using the vast amount of publicly available data collected via satellites, such as air pollution, green space and light at night—all determinants of non-communicable diseases. Existing machine learning–based algorithms enable automated analysis of satel- lite imagery data, but health officials and scientists must know where to find and how to apply these algorithms to measure risk and target interventions.

Aestheticizing And Engendering Disease: The Case Of Tuberculosis, Abigail Dollries

Dartmouth College Master’s Theses

This thesis examines how tuberculosis, known in the nineteenth century as “consumption,” was aestheticized in American cultural and medical discourse, particularly in industrial cities of the North between 1830 and 1850. It addresses the paradox at the heart of the disease’s representation: while tuberculosis was medically pathologized, it was simultaneously romanticized, especially when afflicting elite white women. The central problem explored is how this aestheticization of illness functioned to reinforce gender, class, and racial hierarchies by transforming suffering into a symbol of virtue, refinement, and social status. Using a cultural-historical methodology, this project analyzes a range of sources, including medical …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Intradermal injections of silicone-based fillers for the face and body may cause chronic inflammation and fibrotic reactions in some individuals. Chickens from the UCD 200/206 White Leghorn (WL) line spontaneously develop a fibrotic autoimmune disease known as scleroderma/systemic sclerosis (SSc). Using the SSc-prone UCD and healthy WL chickens, a longitudinal study was conducted to examine the cellular inflammatory responses to intradermal (i.d.) injections of sterile SILIKON-1000. Specifically, the pulp (a skin derivative) of growing feathers (GFs) was i.d. injected with sterile SILIKON-1000 or phosphate-buffered saline (PBS) as injection control (8 and 3 birds/line, respectively; 10 µL/GF; 20 GFs/bird). Two GFs …

Reelin Regulation Of Striatal Physiology And Cocaine Reward, Kasey Lynn Brida

All ETDs from UAB

Drugs of abuse activate defined neuronal populations in brain reward structures such as the nucleus accumbens (NAc), which are thought to promote the enduring synaptic, circuit, and behavioral consequences of drug exposure. While the molecular and cellular effects arising from experience with drugs like cocaine are increasingly well understood, the mechanisms that sculpt NAc neuron participation are largely unknown. Here, we leveraged unbiased single-nucleus transcriptional profiling to identify expression of the secreted glycoprotein Reelin (encoded by the Reln gene) as a marker of cocaine-activated neurons within the rat NAc. Multiplexed in situ detection confirmed selective expression of the immediate early …

Platal Expansion Using The Invisalign Palatal Expander "Ipe", Hassan Chihab

All ETDs from UAB

Palatal expansion has been used in orthodontics to treat a narrow maxilla and to primarily correct posterior dental crossbites. In younger patients, palatal expansion can readily be achieved through opening of the mid-palatal suture, as it is not fused at that age. As the mid-palatal suture matures, expansion will gradually be difficult to achieve, and more dental expansion is obtained rather than skeletal. In addition, there is a tendency to get more dental tipping. Palatal expansion has been recommended not only to correct crossbites but also to improve breathing in patients with sleep disorders such as obstructive sleep apnea (OSA). …

Optimizing Defibrillation Response: A Quality Improvement Initiative In The Cath Lab, Sara Cullis Bsn, Rn

Nursing Publications, Posters, & Presentations

This poster was presented at the 2025 Parkview Nursing Research Symposium.

Patients undergoing diagnostic or emergent procedures in the Cardiac Cath Lab are at risk of developing lethal arrhythmias, which require immediate defibrillation to prevent adverse outcomes. Currently, the use of paddles and the absence of pre-applied defibrillator pads delay response time during critical events, increasing the risk of morbidity and mortality. Additionally, there is a liability when staff assume which patients are “high risk” versus “diagnostic,” as even seemingly low-risk cases can rapidly deteriorate without warning. This quality improvement initiative aims to address this gap by ensuring defibrillator pads …
