Student And Faculty Perceptions Of Live Synchronous Distance Education For Allied Health Students Following Program Expansion To A Rural Campus, 2018 University of Nebraska Medical Center

#### Student And Faculty Perceptions Of Live Synchronous Distance Education For Allied Health Students Following Program Expansion To A Rural Campus, Betsy J. Becker, Kelsey Rutt, Allyson Huntley, Harlan Sayles, Kim Michael

##### Internet Journal of Allied Health Sciences and Practice

Background & Purpose: Distance education (DE) is a means to meet allied health workforce needs in rural locations where healthcare worker shortages are apparent. Five allied health programs were expanded to a rural campus teaching synchronously using distance education technology. The purpose of this convergent parallel mixed methods study was to explore perceptions of allied health students and faculty at two campus locations.

Methods: Quantitative and qualitative information were collected through a survey of students and faculty (physical therapy, physician assistant, and medical imaging [diagnostic medical sonography, radiography, magnetic resonance imaging] programs). Both campuses served as live and distance sites depending on instructor location and area of content expertise. For example, morning courses may be taught live from one campus, and afternoon classes taught live from the other campus. Only one program, physical therapy, offered labs by distance education. Response distributions were compared for questions by campus using Cochran-Armitage trend tests and analyzed de-identified qualitative comments using constant comparisons to establish themes.

Results: Student (n=121) and faculty (n=19) mostly agreed distance education technology was effective for teaching and learning. Significant differences were found in student opinions about receiving a similar educational experience between the two campuses. More students at the Main campus somewhat or strongly disagreed (n=34, 37%) it was similar compared to the Rural campus (n= 5, 17%, p=0.024). There were no comments specifically related to the physical therapy lab experience. Open-ended comment themes included training, purposeful engagement of both campus locations, and setting clear expectations.

Conclusions: Although differences in learning experiences exist between the main and rural campus locations; the results indicated using distance education technology is an effective means to deliver the curriculum. Both students and faculty commented about the lack of experience with the educational technology before implementation. Synchronous, distance education offers the opportunity for program expansion and effective delivery of curriculum content. Using the results of this study can enhance future education in allied health professions using synchronous distance education technology.

#### Improved Target Coverage Of Spinal Metastases Through The Use Of Flattening Filter Free Beams, Laura Bennett

##### UT GSBS Dissertations and Theses (Open Access)

Of the patients that are diagnosed with metastatic disease, up to 40% will develop vertebral osseous metastases. These metastases tend to be located in close proximity to the spinal cord itself, making it difficult to achieve the recommended minimum dose of 14 Gy for single fraction SBRT or 21 Gy1 for three fraction SBRT while maintaining acceptable doses to the cord and cauda equina. This proximity of the target to critical structures has the potential to compromise the efficacy of the radiation treatment plan in favor of reducing normal tissue dose, resulting in poor local control and tumor recurrence ...

#### Defining The Radioresponse Of Mossy Cells, Devon Ivy

##### Electronic Theses, Projects, and Dissertations

Clinical radiotherapy is used to treat a variety of brain tumors within the central nervous system. While effective, it can result in progressive and debilitating cognitive impairment that can diminish quality of life. These impairments have been linked to hippocampal dysfunction and corresponding deficits in spatial learning and memory. Mossy cells are a major population of excitatory neurons located within the dentate hilus and highly involved in hippocampal circuitry. They play critical roles in spatial navigation, neurogenesis, memory, and are particularly vulnerable to a variety of neurotoxic insults. However, their sensitivity to ionizing radiation has yet to be investigated in ...

#### Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin

##### Senior Honors Theses

The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research ...

#### Development Of A Positron-Emitting Surrogate Microsphere For Image-Based Dosimetry In Yttrium-90 Radioembolization Therapy, Gregory D. Chambers

##### Nuclear Engineering ETDs

Radioembolization of liver tumors using yttrium-90 (Y-90) labeled microspheres is a proven method of treatment. The primary decay mode of Y-90 is beta-minus decay. The electrons produced during decay deliver a cytotoxic radiation dose in a localized volume. The radiation dose is sufficient to kill tumor cells yet spare the normal liver. The Y-90 microspheres are delivered via a catheter that has been placed in an artery that supplies blood to the tumor. Microspheres are injected and the blood distributes the microspheres. The current practice involves two separate procedures. The first procedure is an assessment of the vasculature of the ...

#### Benefit Of Intensity Modulated Bolus Electron Conformal Therapy For Post Mastectomy Chest Wall Irradiation, John Doiron

##### LSU Master's Theses

Purpose: The delivery of post-mastectomy radiotherapy (PMRT) with bolus electron conformal therapy (BECT) for patients with left-sided breast cancer can reduce second cancer complication probability (SCCP) compared to modern rotational intensity modulated x-ray (IMXT) techniques such as volumetric modulated arc therapy (VMAT) or Tomotherapy. However, rotational IMXT yields superior levels of dose homogeneity compared to BECT. This study investigates the use of intensity modulated (IM) BECT (IM-BECT) to improve dose homogeneity in the chest wall (CW) region of the PMRT planning target volume (PTV) abutted to parallel opposed IMXT tangents for the remaining PTV for a clinically-representative set of patients ...

#### The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, Skyler J. Pavlish-Carpenter

##### Honors in the Major Theses

Background: Disruptive technology describes technology that is significantly more advanced than previous iterations, such as: 3D printing, genetic manipulation, stem cell research, innovative surgical procedures, and computer-based charting software. These technologies often require extensive overhauls to implement into older systems and must overcome many difficult financial and societal complications before they can be widely used. In a field like healthcare that makes frequent advancements, these difficulties can mean that the technology will not be utilized to its full potential or implemented at all.

Objective: To determine the inhibiting factors that prevent disruptive technology from being implemented in conventional healthcare.

#### Proposed Method For Measuring The Let Of Radiotherapeutic Particle Beams, Stephen D. Bello

##### Physics & Astronomy ETDs

The Bragg peak geometry of the depth dose distributions for hadrons allows for precise and effective dose delivery to tumors while sparing neighboring healthy tissue. Further, compared against other forms of radiotherapeutic treatments, such as electron beam therapy (EBT) or photons (x and $$\gamma$$-rays), hadrons create denser ionization events along the particle track, which induces irreparable damage to DNA, and thus are more effective at inactivating cancerous cells. The measurement of radiation's ability to inactivate cellular reproduction is the relative biological effectiveness (RBE). A quality related to the RBE that is a measurable physical property is the linear ...

#### Epoxyeicosatrienoic Acids Regulate Adipocyte Differentiation Of Mouse 3t3 Cells, Via Pgc-1Α Activation, Which Is Required For Ho-1 Expression And Increased Mitochondrial Function, Maayan Waldman, Lars Bellner, Luca Vanella, Joseph Schragenheim, Komal Sodhi, Shailendra P. Singh, Daohong Lin, Anand Lakhkar, Jiangwei Li, Edith Hochhauser, Michael Arad, Zbigniew Darzynkiewicz, Attallah Kappas, Nader G. Abraham

Epoxyeicosatrienoic acid (EET) contributes to browning of white adipose stem cells to ameliorate obesity/diabetes and insulin resistance. In the current study, we show that EET altered preadipocyte function, enhanced peroxisome proliferation-activated receptor γ coactivator α (PGC-1α) expression, and increased mitochondrial function in the 3T3-L1 preadipocyte subjected to adipogenesis. Cells treated with EET resulted in an increase, P < 0.05, in PGC-1α and a decrease in mitochondria-derived ROS (MitoSox), P < 0.05. The EET increase in heme oxygenase-1 (HO-1) levels is dependent on activation of PGC-1α as cells deficient in PGC-1α (PGC-1α knockout adipocyte cell) have an impaired ability to ...
