Analyzing The Survival Rate Of Clinically Pathogenic Bacteria On Occupational Therapy Devices Used During Full Hip Replacement Rehabilitation, Meredith Rippy

Honors Theses

An increasing concern of the healthcare system has been that of Healthcare-Associated Infections (HAIs). HAIs currently account for approximately 1.7 million infections and 99,000 deaths per year in United States hospitals. HAI’s (formerly called nosocomial infections) are defined as infections that develop in patients who have been in residence in a healthcare facility (i.e., in-patient clinics) for 48 hours or longer and who previously had no evidence of infection prior to admission. Consequences of HAIs include increased length of hospital stay, exposure to high frequency antibiotics, sepsis, and in unfortunate cases, death. In out-patient environments where patients are receiving rehabilitative …


The Use Of Spectral Imaging To Reveal Inorganics And Organics Identity In The Biological Samples, Qamar Alshammari 2022 Chapman University

The Use Of Spectral Imaging To Reveal Inorganics And Organics Identity In The Biological Samples, Qamar Alshammari

Pharmaceutical Sciences (PhD) Dissertations

The wavelength is used to identify the exact location and quantify the number of molecules in the spectral imaging system. It aids in identifying materials and studying their quantities by examining how they interact with light. A traditional spectrometer provides spectrum information of chemical compounds, while standard imaging provides the intensity at each pixel of the image. Spectral imaging (SI) combines these two aspects by equipping intensity and spectral data for each pixel. In biomedical research, it is important to assess the inorganics/organics molecules to understand drug activity, cellular toxicity, and distribution. Using the microscopy technique, we found for the …

Targeting Metabolic Adaptations To Anti-Angiogenic Therapy In Ovarian Cancer, Deanna M. Glassman, Deanna Glassman

Dissertations and Theses (Open Access)

ABSTRACT

Background: Ovarian cancer is the most lethal gynecologic malignancy. Despite modest clinical improvements with anti-VEGF antibody (AVA) therapy, adaptive resistance is nearly ubiquitous and additional therapeutic options are limited. A dependence on glutamine metabolism, via the enzyme glutaminase (GLS), is a known mechanism of adaptive resistance.

Purpose: To assess the efficacy of a glutaminase inhibitor as a means of exploiting the metabolic vulnerability of glutamine dependence that develops as a result of adaptive resistance to AVA therapy.

Experimental Design: We used a glutaminase inhibitor (GLSi) synthesized at MD Anderson Cancer Center for all in vitro and in vivo experiments. …

A Neurophysiological Investigation Of Listening Effort In Normal Hearing Adults Using Fnirs And Pupillometry, Jessica Defenderfer 2022 University of Tennessee Health Science Center

A Neurophysiological Investigation Of Listening Effort In Normal Hearing Adults Using Fnirs And Pupillometry, Jessica Defenderfer

Theses and Dissertations (ETD)

Real-world conversations are often accompanied by some sort of interference that challenges the clarity of the speaker’s message, causing listeners to exert more effort to understand speech. Previous research has demonstrated that when listening to speech becomes difficult, various regions of the brain are recruited beyond those which engage during optimal listening conditions. However, the neural correlates that underly listening effort are not fully understood. Importantly, the pupillary response can be used to index listening effort, such that pupil size increases with increasing cognitive demand. I proposed that pupillometry can be used to characterize the cortical response, such that changes …

Electrical & Computer Engineering Faculty Publications

Plasma medicine refers to the application of nonequilibrium plasmas at approximately body temperature, for therapeutic purposes. Nonequilibrium plasmas are weakly ionized gases which contain charged and neutral species and electric fields, and emit radiation, particularly in the visible and ultraviolet range. Medically-relevant cold atmospheric pressure plasma (CAP) sources and devices are usually dielectric barrier discharges and nonequilibrium atmospheric pressure plasma jets. Plasma diagnostic methods and modelling approaches are used to characterize the densities and fluxes of active plasma species and their interaction with surrounding matter. In addition to the direct application of plasma onto living tissue, the treatment of liquids …

Articles

Confocal Raman microscopy (CRM) has become a versatile technique that can be applied routinely to monitor skin penetration of active molecules. In the present study, CRM coupled to multivariate analysis (namely PLSR—partial least squares regression) is used for the quantitative measurement of an active ingredient (AI) applied to isolated (ex vivo) human stratum corneum (SC), using systematically varied doses of resorcinol, as model compound, and the performance is quantified according to key figures of merit defined by regulatory bodies (ICH, FDA, and EMA). A methodology is thus demonstrated to establish the limit of detection (LOD), precision, accuracy, sensitivity (SEN), and …

Doctor of Nursing Practice Projects

Abstract Purpose/Background Despite the increased use of palliative care in adults, only a tiny percentage of children with life-limiting illnesses or life-threatening conditions receive palliative care before dying. Palliative care has low utilization, and consults are often made late in a child’s hospitalization or diagnosis. Palliative care remains underutilized among hospitalized pediatric patients resulting in unnecessary treatments, costly and lengthy hospitalizations, and deaths occurring in the intensive care unit (ICU) rather than at home. The purpose of this scoping review is to evaluate current literature to determine the use and effect of pediatric palliative care, specifically, whether consultation of palliative …

Doctor of Nursing Practice Projects

Purpose/Background Psychosis is a psychiatric disorder characterized by hallucinations and delusions. These symptoms not only negatively impact a patient’s quality of life but can also make treatment compliance difficult. This lack of treatment compliance ultimately leads to higher relapse and re-hospitalization rates among this population. Thus, it is imperative that effective treatments are developed, utilized, and made readily available for patients. Antipsychotics are medications that block dopamine D2 receptors. These medications are used for psychosis to help to improve patient outcomes. Currently, two routes of antipsychotic administration are available, oral antipsychotics or long-acting antipsychotic injections (LAIs). Oral antipsychotic administration requires …

Doctor of Nursing Practice Projects

Purpose/Background Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Rates have steadily increased in recent years due to high rates of obesity, smoking, and sedentary lifestyles. Screening for the disease can lead to early detection and reduced morbidity/mortality, yet screening rates remain low. Existing literature is extensive in discussing methods to increase CRCS adherence; therefore, a scoping review allows for increased understanding of barriers to CRCS and how to address those barriers to increase screening compliance.

Methods A literature search was completed from September 2020 to October 2021. Multiple databases were used, including …


Using Machine Learning To Recognize Chronic Rhinosinusitis, Irene Liu '23 2022 Illinois Mathematics and Science Academy

Using Machine Learning To Recognize Chronic Rhinosinusitis, Irene Liu '23

Student Publications & Research

Chronic Rhinosinusitis (CRS) is a nasal disease characterized by the inflammation of the mucosa and paranasal sinuses with a duration of at least 12 consecutive weeks. So, to diagnose CRS, one needs to keep a record of their symptoms for ~12 weeks before they are recommended to get a tomography which will allow physicians to classify them as a patient with CRS or without. This is a timely and costly process; thus, machine learning should be used to speed the process up. Since patients with CRS have more obstructed noses, the sound produced should be different than an individual without …
