Social-Ecological Factors Affecting Patient Shield Use Among Radiologic And Computed Tomography Technologists, Megan Housenick-Lee
Social-Ecological Factors Affecting Patient Shield Use Among Radiologic And Computed Tomography Technologists, Megan Housenick-Lee
Electronic Theses and Dissertations
Medical radiation is estimated to contribute to over 200,000 deaths annually. Recent increases in the use of radiation-producing medical imaging examinations have led to increasing cumulative radiation dose to the general public. Multiple measures have been taken to address this alarming trend, including physician education, technologist education on dose reduction, and equipment-facilitated dose reduction techniques. Shield use can reduce the primary beam by up to 95%. Medical imaging technologists are the primary individuals responsible for applying shielding during an examination. Currently, literature shows that technologists are not shielding individuals as often as they should.
After pilot testing, medical imaging technologists …

Effects Of Acute Sepsis On Renal Structure And Sympathetic Innervation In Mice, Tuqa Alkhateeb
Electronic Theses and Dissertations
Sympathetic nerves are important for renal physiology and sepsis pathophysiology. A recent study showed sprouting of sympathetic nerves in spleen of septic mice. This study was done to test if renal sprouting of sympathetic nerves also happens and to investigate renal morphology in septic mice. Cecal ligation and puncture (CLP) was used to induce sepsis and kidneys were removed for evaluation. Bowman’s space was diminished with cortical bubble cells present suggestive of acute renal pathology, however, renal function was unchanged. Acute sepsis did not affect either renal sympathetic innervation or non-neuronal cholinergic cells. Mouse kidneys had more epinephrine (EPI) than …

This study compares total expenditures between beneficiaries enrolled in traditional Long-Term Care (LTC) and beneficiaries enrolled in Home and Community Based Services (HCBS) in a Quasi-Experimental Simple Ex Post Facto study utilizing multiple linear regression with inverted propensity score weighting. The results demonstrated, during the two years of the study period, that total expenditures were on average $14,565.03 (with a p-value oflessfor the total two years of the study, for HCBS beneficiaries when compared to their LTC counterparts. There remains today a belief that expenditures of elderly, dual beneficiaries electing to age-in-place for supported self-care expend less than that of …
Biomechanical Testing Of An Exercise For Strengthening The Proximal Femur., Alyssa Osbourne
Biomechanical Testing Of An Exercise For Strengthening The Proximal Femur., Alyssa Osbourne
Electronic Theses and Dissertations
Based on the principles of cutting edge bone remodeling research, a unique therapeutic exercise device was designed specifically to improve bone quality at the most critical location of the proximal femur prone to fracture: the superior-lateral femoral neck where the fracture first initiates during a fall. The exercise/device is intended to work by inducing enough strain in the bone to stimulate the body’s natural bone remodeling mechanisms to increase bone density in the proximal femur and consequently prevent a fracture from arising if a fall to the side does occur.
In order to test the proposed exercise, experiments simulating the …

Targeting The Glucose Metabolism Of Myeloid-Derived Suppressor Cells (Mdscs) To Stimulate Cancer Immunity., Jaspreet Grewal
Targeting The Glucose Metabolism Of Myeloid-Derived Suppressor Cells (Mdscs) To Stimulate Cancer Immunity., Jaspreet Grewal
Electronic Theses and Dissertations
Myeloid derived suppressor cells (MDSCs) are a heterogeneous group of immature myeloid cells that are significantly increased in cancer patients and correlate with higher stage and poor prognosis. MDSCs negatively modulate anti-tumor immunity, suppress T cell activity, promote angiogenesis and increase the risk of metastasis. In this study, we report that monocytic-MDSCs (M-MDSCs) but polymorphonuclear-MDSCs (PMN-MDSCs) over-express 6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatases 3 (PFKFB3), an important regulator of glycolysis. Furthermore in the melanoma model, M-MDSCs but not PMN-MDSCs suppressed T cell function which correlated with PFKFB3 over-expression and increased rate of glycolysis. PFKFB3 inhibition with the first-in-class small molecule inhibitor, PFK-158 reversed M-MDSC …
Enhancing Cell Therapy For Ischemic Cardiomyopathy., Michael J. Book
Enhancing Cell Therapy For Ischemic Cardiomyopathy., Michael J. Book
Electronic Theses and Dissertations
Cardiac cell therapy using cardiac mesenchymal cells (CMC) significantly reduces ventricular dysfunction in patients with ischemic cardiomyopathy. Despite the improvement in function, a modest number of CMCs survive in the heart post-transplantation. In this study, we sought to improve the survival and retention of transplanted CMCs to prolong the therapeutic benefits afforded by cardiac cell therapy. To do this, we targeted the enzyme telomerase (TERT), known to be active in some highly proliferating cells (e.g. germ, stem). TERT is responsible for preventing telomere attrition, thereby allowing continued proliferation. TERT has also been shown to be protective, improve cell migration and …
Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau
Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau
Electronic Theses and Dissertations
There is a general consensus that the level and the severity of spinal cord injury (SCI) impacts chronic cardiac abnormalities such that high thoracic and cervical SCI are the most severely affected. Furthermore, the extreme degree of immobility/inactivity experienced by the persons with SCI has implications on cardiac decline. Yet it has been difficult to separate the relative contributions of the decentralized autonomic nervous system (ANS) and the immediate and profound inactivity to chronic cardiac abnormalities. As such, this body of work sought to characterize a contusion SCI that results in persistent CV dysfunction. Echocardiography, Dobutamine stress echocardiography and pressure …

Methods: An electronic survey was distributed to 20,000 current and past meal replacement program participants. Personality style was assessed via the Ten Item Personality Inventory, providing individual perceptions of each of the Big Five personality domains (extraversion, agreeableness, conscientiousness, emotional stability, and openness to experience). The Working Alliance Inventory (Short Revised) was used to assess three key perceptions of health coaching: 1) agreement on the goals of coaching (goal), 2) agreement on the tasks of …
The Effect Of Sport Participation On Bone, Maggie M. Minett
The Effect Of Sport Participation On Bone, Maggie M. Minett
Electronic Theses and Dissertations
Mechanical loading – or physical activity – is essential in the bone remodeling process as well as optimizing the densitometric and geometric properties of bone throughout the lifespan. Participation in sports is a common mode of physical activity that can enhance bone mass accrual at younger ages and facilitate bone mass maintenance at older ages. Research suggests that sport participation continued from adolescence into high school and college provides added benefits on aBMD and cortical bone measures and these benefits remain 10-15 years after retirement from sport. However, in most studies, the higher rates of bone loss after sport cessation …
