Adhesion Of Antibiotic-Resistant Bacteria To Thermoplastic Materials Used In Fabricating Medical Devices: Patient Consequences, Dev V. Mehta

Poster Presentations

Burn injury patients wear supportive orthoses made by heat-forming sheets of thermoplastic material (Figs. 1 & 2). Bacteria cause severe soft tissue infections in patients wearing contaminated orthoses. Thermoplastic medical devices can develop biofilms that include antibiotic-resistant (AR) bacteria, which significantly reduces the number of available treatment options. A biofilm is a community of microorganisms that share resources allowing them to exist in a nutrient-limited environment. Biofilm microbes secrete extracellular polymeric substance (EPS) that attaches them firmly to a substrate surface while protecting them from harmful substances, including antibiotics. Bacteria living within biofilms on inanimate surfaces can survive for extended …

Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta

Honors Theses

This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …

Clinical Utility Of Opencap Motion Analysis In Lower Limb Prosthesis Users, Sarahi Fernandez Leon

Honors Program Theses and Research Projects

The use of prosthetics has gradually increased due to various diseases, and it is estimated that 35-40 million people are prosthetic/orthotic users, with the number estimated to increase to two billion by 2050. Mobility has been determined to be a strong predictor of quality of life. There are various ways to measure mobility and predict outcomes in lower-limb amputees (LLA), such as self-report and performance-based measures. However, these come with many limitations, showcasing the need for quantitative measures of gait parameters to allow for better development of prosthetic components. Motion analysis tools are expensive and time consuming, but an inexpensive, …

Introduction: Ehlers-Danlos Syndrome is an inheritable connective tissue disorder which results from a genetic mutation that alters the body’s ability to produce collagen. The most common subtype of Ehlers-Danlos Syndrome is hEDS, which leads to hypermobility and hyperextensibility and can cause frequent joint dislocations.

Methods: A review of literature was performed to compare each treatment based on reported results. The types of studies reviewed …

Outpatient Fall Prevention In Ambulatory Adults 65 Years Old And Over, Dorothy L. Osborne-White

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Background: In the United States (U.S.), falls are the leading cause of injury among adults 65 and over, resulting in 36 million falls yearly (Moreland et al., 2020). According to the Centers for Disease Control and Prevention (CDC, 2023), one in four older adults experiences a fall each year. Falls are the world's second most prominent cause of accidental deaths (World Health Organization [WHO], 2021). Falls are the leading cause of both fatal and non-fatal injuries among older adults (Moreland et al., 2020).

Methods: A quality improvement project that included a fall bundle was implemented in a primary clinic. A …

Comparison Of A Dynamic Ankle Orthosis To A Walking Boot For Preserving Ankle Joint Motion And Reducing Tibial Bone Load And Strain, Perri Johnson Jr.

Theses and Dissertations (ETD)

Tibial stress fractures are a common overuse injury accounting for 21.9 – 69% of stress fractures among runners and 24 – 51.2% of stress fractures in military cadets. Current treatment involves wearing a walking boot for 3 – 12 weeks, which limits ankle motion and causes lower limb muscle atrophy. A Dynamic Ankle Orthosis (DAO) provided a distractive force that offloaded the ankle and retained sagittal ankle excursion during walking. It remains unclear how tibial loading is affected by a walking boot or the DAO. This thesis presents a feasibility study confirming the offloading effects of the DAO on tibial …

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

A New Technique To Improve The Operation Of Prosthetic Limbs During Muscle Fatigue, H. Albunashee, G. Rasool, K. Iqbal, G. White

Journal of the Arkansas Academy of Science

Prosthetic limbs hold a promise to renew the quality of life for the amputee. Neural commands are decoded via a classifier to generate control signals for the prosthetic devices. In the literature, many challenges and limitations have been identified that affect the prosthesis operation. One such drawback is muscle fatigue which degrades the surface electromyogram (sEMG) signals, and consequently, the performance of the deployed classification algorithm declines from 90% to 50% of average accuracy. We used a new technique using the Linear Discrimination Analysis (LDA) algorithm and the muscle synergy-based task discrimination (MSD) algorithm to improve the classification accuracy. In …
