The purpose of this study was to find an appropriate solution in reducing inflammation around the ankle joint for Rheumatoid Arthritis (RA) patients, so they are able to increase their endurance and improve their overall quality of life. RA patients have to deal with a significant amount of complications that include chronic inflammation, continuous pain in their joints, and overwhelming stress. In addition, it is very common for RA patients to develop severe mental issues that only makes matters worse. As a result, it is imperative that treatments are provided to RA patients to improve their current situation. Three devices from the current market, made for reducing inflammation of the ankle, were chosen for evaluating the effectiveness of each device. It was determined that with 95% confidence that the Gonicc Professional Foot Sleeve was the most effective in reducing inflammation. A prototype was developed based on the feedback of the participants. Further improvements, the prototype will be compared against the Gonicc Professional Foot Sleeve to determine which is the best solution to improve millions of RA patients' lives.

Intrauterine devices, or IUDs, are long-lasting forms of birth control that have effectiveness comparable to sterilization, while they can be removed at any time. However, the insertion process can be very painful, especially for individuals who have never given vaginal birth. The most common form of pain management for this procedure is having the patient take an ibuprofen an hour or so before the procedure, but this only helps with cramping afterwards, not the acute pain caused by insertion. Pain, and anxiety and fear regarding potential pain, serve as a barrier between users and this highly effective form of birth control. This report uses COMSOL to model lidocaine diffusion from 4% topical hydrogel into the cervix (the main site of acute pain during IUD insertion) over 180 minutes. The cervix was modeled axisymmetrically, using average experimental values for cervix size. Concentration at four specific probe points were measured over time and compared at different concentrations. A sensitivity analysis was performed by adjusting the diffusion coefficient of the epithelial layer. This model was developed to serve as a predictor for future drug applications across the cervix, to determine in advance whether a novel formulation of drug would be effective to significantly reduce pain. This model may be refined further with experimental values for the constants, and with further testing of different lidocaine concentrations.

In this thesis report, I aim to explain the realities of humanitarian efforts to implement solar panel systems in rural communities, the challenges they face, and why they fail. I will also compare case studies of both unsuccessful and successful projects, which will lead to a proposed solar panel system design for a single home completed in collaboration with Arizona State University's Engineering Projects in Community Service (EPICS) Program for the Shonto Solar project.

SUMMARY: A failed attempt to conduct a systematic review of disparities in racial inclusivity in stroke rehabilitation research: A call to action Group Members: Adeline Beeler & Mikayla McNally Faculty Mentor(s): Dr. Sydney Schaefer & Dr. Keith Lohse Topic Overview: Stroke is responsible for the death of an individual every four minutes in the United States. While all Americans are gravely affected by this statistic, Black Americans are at a significantly increased risk of first stroke incidence when compared to their white counterparts, majorly due to heightened prevalence of stroke risk factors. Not only does race contribute as a factor in stroke incidence, but it also has a considerable impact in the physical impairment of Black Americans following stroke occurrence. While it still remains unclear as to whether or not stroke plays a significant role in stroke rehabilitation efforts, there is a clearly demonstrated need for increased reporting or participation of Black Americans in stroke rehabilitation clinical trials to have the ability to conduct a systematic review of these racial disparities in the near future. In the analysis of 36 stroke rehabilitation-related clinical research studies, 80% of selected trials failed to report any participant racial demographics, with 77.3% of the NIH-funded trials not reporting, as well. Out of the 7 trials that did provide some sort of participant racial information, only 5 successfully provided statistically significant racial data compared to the remainder that simply categorized participants’ race as “white” or “other.” In order to fully investigate the effects of race on stroke rehabilitation, it is imperative that researchers collect and report equally distributed and diverse participant racial data when publishing clinical research. Potential methods of improvement for researchers to include more racially diverse subject populations include more comprehensive and in-depth advertising and recruitment strategies for their studies. Research Methods: In order to produce accurate analyses of the current state of the relationship between race and stroke rehabilitation efforts, 36 stroke rehabilitation clinical research trials from various locations across the United States were identified using the Centralized Open-Access Rehabilitation Database for Stroke (SCOAR). These trials were evaluated in order to extract relevant data, such as number of trial participants, average age of participants, if the research trial was funded by the National Institute of Health (NIH) or not, and any reported participant racial demographic details. Trends across these categories were compared between all trials to determine if any disparities existed in providing data sufficient to support the relationship between varying racial populations and stroke rehabilitation efforts. Future Project Efforts: Future efforts will include the completion of submitting a Point of View/Directions for Research article for publication to offer an opportunity for clinical and basic researchers to examine the discrepancies surrounding racial inclusivity in stroke rehabilitation clinical research. The aim is to improve the ability of clinicians to interpret the literature, translate research studies into practices, and better direct future experiments. Further identification of stroke rehabilitation clinical research trials will be necessary, as well as modifications to current written work content.

Following a study conducted in 1991 supporting that kinesthetic information affects visual processing information when moving an arm in extrapersonal space, this research aims to suggest utilizing virtual-reality (VR) technology will lead to more accurate and faster data acquisition (Helms Tillery, et al.) [1]. The previous methods for conducting such research used ultrasonic systems of ultrasound emitters and microphones to track distance from the speed of sound. This method made the experimentation process long and spatial data difficult to synthesize. The purpose of this paper is to show the progress I have made in the efforts to capture spatial data using VR technology to enhance the previous research that has been done in the field of neuroscience. The experimental setup was completed using the Oculus Quest 2 VR headset and included hand controllers. The experiment simulation was created using Unity game engine to build a 3D VR world which can be used interactively with the Oculus. The result of this simulation allows the user to interact with a ball in the VR environment without seeing the body of the user. The VR simulation is able to be used in combination with real-time motion capture cameras to capture live spatial data of the user during trials, though spatial data from the VR environment has not been able to be collected.

Objective: To determine if patients’ insurance status or the income level of their zip code of residence affect their quality of life or overall survival after enrollment in clinical trials for cancer treatment. Methods: Data were collected from cancer treatment trials conducted through the North Central Cancer Treatment Group and the Alliance for Clinical Trials in Oncology. 700 subjects with baseline quality of life scores were analyzed to explore potential differences in quality of life indicators by insurance group. 624 patients with valid US zip codes were also analyzed based on the median household income of their zip code to determine any associations with quality of life. Overall survival was also analyzed by insurance group and by income quartile. Results: 700 subjects (mean age 59 years, 53% male) were included. 49% had private insurance only, 30% had public insurance only, 8.9% had both private and public insurance, 1.4% had no insurance, and 10% had other insurance. 13% of patients came from zip codes in the bottom quartile by median income, 20% came from the second quartile, 25% from the third quartile and 42% from the top quartile. No significant differences were found in baseline quality of life scores between insurance groups or income quartiles. Patients with both private and public insurance had higher baseline fatigue scores compared to only private, only public, or other insurance. No significant difference was found in baseline fatigue scores by income quartile. No significant differences were found in overall survival by insurance group or income quartile. Conclusions: Patients with both private and public insurance may need more extensive interventions than patients with other insurance statuses due to their higher baseline fatigue scores. Future studies are needed to further investigate the effects of neighborhood advantage level on quality of life indicators.
