As such, the development of better predictive methods is vital for improving patient outcomes and overall quality of care. Heart rate variability (HRV) is a measure of the heart’s complex beating patterns, giving medical professionals additional insight into patient health. Previous research has demonstrated the potential use of heart rate variability as a metric for patient mortality prediction for various conditions, however more work is necessary to validate HRV as a metric …

Expand Nemt Across Central And Western Nebraska, Bri Parr

Theses/Capstones/Creative Projects

The average age of adults in the US is increasing, especially in rural areas. Approximately 60 million individuals live in the rural US, including millions of Medicare beneficiaries. Older rural Americans are more likely to be in poverty, unhealthy, and medically underserved. They rely heavily on government health insurance programs, such as Medicare, to provide for their health care needs. Unfortunately, for many older adults living in rural areas, health care is both difficult to access or in some cases completely unavailable. This is due to several factors, including the lack of specialist care in rural areas (mental health specialists, …

Medical Ethics: From The Perspective Of Undergraduate Pre-Health Students, Hannah Im

Theses/Capstones/Creative Projects

The burden of ethical decision-making is a significant contributor to compassion fatigue in healthcare professionals. Due to the impact of moral conflicts, it may be beneficial to reassess the effectiveness of current ethics education and training. While previous studies have surveyed a range of medical professionals and students, it remains unclear if exposure to ethics topics during undergraduate education could better prepare future healthcare workers. Thus, there is a need to identify the necessity of introducing ethics courses into the required pre-health curriculum. The following study took the first step to gauge this by surveying undergraduate pre-health students on their …

Uno Student Access To Emergency Contraception: A Needs Assessment, Annika Kuchar

Theses/Capstones/Creative Projects

Emergency contraception (EC) is a common method of contraception that helps prevent ovulation before implantation of an egg inside a uterus. Among college students, EC can be utilized to prevent unplanned pregnancies that could potentially prevent someone from completing their degree. College students can face unique barriers when trying to access EC including transportation, privacy, financial, or mental/emotional barriers. The purpose of this study was to determine what barriers students at the University of Nebraska at Omaha (UNO) face when trying to access EC, and what future accommodations they would utilize if given the option. The study surveyed 147 UNO …

Optimization Of The Musculoskeletal Simulation In Estimation Of Metabolic Cost, Arash Mohammadzadeh Gonabadi, Philippe Malcolm

UNO Student Research and Creative Activity Fair

Energy from food is supplied to the human body in the form of chemical energy in the muscles. This metabolic energy expenditure is one of the main determinants of the way we walk, and indirect calorimetry measurements are an essential tool for understanding how increases in metabolic cost restrict the mobility of clinical populations. Respiratory oxygen consumption measurements allow recording of the average metabolic cost of walking. However, the time required for these measurements prevents assessing metabolic rate in patients who cannot walk long enough. Musculoskeletal modeling techniques allow to estimate average muscle energy expenditure during locomotion in conjunction with …

How Can Actuation Timing And Magnitude Of A Bilateral Semi-Rigid Hip Exoskeleton Optimize Metabolic Cost, Arash Mohammadzadeh Gonabadi, Prokopios Antonellis, Sara Myers, Iraklis Pipinos, Philippe Malcolm

UNO Student Research and Creative Activity Fair

Semi-rigid exoskeletons could combine some advantages of rigid and soft approaches. The purpose of this study was to investigate the effects of timing and magnitude of assistance from a semi-rigid hip exoskeleton. For ten participants, we tested ten conditions that were combinations of 5 different end-timings, ranging from 21% to 49%, and 2 different moment magnitudes ranging from 0.06 to 0.12 Nm.kg^-1. The participants walked in two reference conditions: a condition without actuation and a condition without the exoskeleton. A semi-rigid hip exoskeleton could alter metabolic rate. However, to produce a net assistive effect, it is necessary to …

Considerations For Implementing An Ankle Foot Orthosis To Improve Mobility In Peripheral Artery Disease, Ayisha Bashir, Sara A. Myers, Danae Dinkel, Iraklis Pipinos

UNO Student Research and Creative Activity Fair

An ankle- foot orthosis (AFO) can contribute to push-off during walking by storing energy from heel strike in the rigid strut and subsequently returning force during push-off. Peripheral artery disease (PAD), a manifestation of systemic atherosclerosis, blocks the arteries supplying blood to the legs and causes muscle pain and weakness, which leads to difficulty walking. Wearing an AFO can help patients with PAD walk better. In our study, subjects decided whether to adopt or not adopt the AFO. Our goal is to assess early AFO intervention withdrawal (wAFO) and AFO intervention completion (cAFO). Participants (n=21) were recruited and consented to …

Ankle–Foot Orthosis Alters Biomechanics Of Lower Extremities During Walking, Farahnaz Fallah Tafti, Iraklis Pipinos, Jason Johanning, Hafizur Rahman, Mahdi Hassan, Sara Myers

UNO Student Research and Creative Activity Fair

Lower extremity peripheral artery disease (PAD) is a cardiovascular condition caused by narrowed or blocked arteries supplying blood to the legs. Leg pain and myopathy significantly impair gait from the first step. Using AFO may assist the gait and prolong the distance patients with PAD can walk. This study aimed to investigate the effect of AFO on the gait biomechanics of patients with PAD. Fourteen Participants walked over the force platforms with and without an AFO and kinetics and kinematics were combined to quantify torques and powers of the hip, knee, and ankle joints. Our data demonstrate that use of …

UNO Student Research and Creative Activity Fair

Predicting sports games outcomes is an endless pursuit shared by stakeholders ranging from fans to coaches to data scientists. We have begun investigating the value of positional data recorded during basketball gameplay with the goal of predicting outcomes from team dynamics as they emerge. We approached this problem by analyzing the “shape” of team movements on the court and investigated whether team dynamics in NBA games mimicked long-range correlated patterns observed in other team contexts. We analyzed 622 NBA games from an archival data set, including all area time series obtained for each of the four quarters. We fit a …

Design And Development Of Software With A Graphical User Interface To Display And Convert Multiple Microscopic Histology Images, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Histological images are widely used to assess the microscopic anatomy of biological tissues. Recent advancements in image analysis allow the identification of structural features on histological sections that can help advance medical device development, brain and cancer research, drug discovery, vascular mechanobiology, and many other fields. Histological slide scanners create images in SVS and TIFF formats that were designed to archive image blocks and high-resolution textual information. Because these formats were primarily intended for storage, they are often not compatible with conventional image analysis software and require conversion before they can be used in research. We have developed a user-friendly …

Previous research has sought to determine precursors to injury by investigating physical limitations including hip internal rotation deficits. This study aims to build upon previous research by measuring joint mobility and forces placed on the lower back during the golf swing. Specifically, it evaluates active range of motion of both …

Ingredient Classification Using Food Ontology, Ricky Flores

UNO Student Research and Creative Activity Fair

A food label provides some of the most crucial information for a food product. The food label is a key resource for many health-conscious consumers for understanding ingredients. It is also vital for individuals to avoid food allergens or help patients follow dietary recommendations. While the food labels in the United States are regulated by the Food and Drug Administration (FDA) many labels contain additional information or statements that are not regulated. Moreover, the food label may be complex or contain terminology that the layperson may not understand. Evidence has indicated that consumers often find nutrition labels confusing, especially when …
