The Influence Of Neurocognitive Impairment On Treatment Outcomes Among Drug-Involved People Living With Hiv/Aids, Ifeoma O. Ezeabogu

Master's Theses

Drug- and sex-related HIV risk behaviors and sub-optimal adherence to HIV medication regimens can jeopardize the health of HIV–infected injection drug users (IDUs) and threaten community health. Findings to date indicate that it is feasible to deliver a brief behavioral risk reduction/medication adherence group intervention to HIV-infected IDUs in a community-based setting. Being adherent to HAART or being able to successfully participate in behavioral interventions targeting adherence and harm reduction often requires a relatively high level of cognitive abilities. HIV infection and substance abuse are known to independently affect the central nervous system and this can result in neuro-cognitive impairment. …

Epicardial Wireless Pacemaker For Improved Left Ventricular Resynchronization (Conceptual Design), Rodney J. Hawkins

Master's Theses

The human body is a well tuned mechanism where systems work in synergy to provide a healthy quality of life. The human circulatory system transports oxygenated blood from the heart to the rest of the body delivering the proper nutrients for cells to function. When the heart malfunctions, serious complications can arise leading to sudden cardiac arrest. Congestive heart failure (CHF) is one heart disease that affects the synchrony of the heart’s ventricles.

Cardiac resynchronization therapy (CRT) has been widely accepted as a treatment for CHF. Similar to traditional dual chamber pacing techniques, CRT adds a pacing lead to stimulate …

Milliamperage-Seconds, Kilovoltage And Patient Dose In Computed Radiography, Grace Stewart

Master's Theses

Radiographic techniques were applied to a human simulation pelvis phantom with evaluations of the resultant image analyzed by a designated radiologist. Results indicate that a lower patient dose is received when coupled with an increase in the tube voltage. Images analyzed demonstrated little noise variation between images, which indicates the ability to lower patient dose while maintaining quality images.

Factors That Influence Organizational Commitment In Nurse Manager / Subordinate Dyads, Laurie Stegeman

Master's Theses

According to Buerhaus, Auerbach and Staiger (2009), despite the current easing of the nursing shortage due to the recent recession and many nurses putting off retirement, the nursing shortage is projected to grow to approximately 260,000 registered nurses by the year 2025. Creating a work environment within nursing practice that is healthy and productive is essential to maintaining an adequate nursing workforce (Shirey, 2006). Nurse leaders play a vital role in creating work environments that are healthy, positive and productive. The problems associated with decreasing levels of organizational commitment (OC) among staff nurses ultimately resulting in losing dedicated, skilled nursing …

Intimidation And Disruptive Behaviors In The Health Care Setting, Janelle Wade

Master's Theses

Intimidation and disruptive behavior can undermine patient care and cause staff dissatisfaction and turnover of professionals in the health care setting. These behaviors have been linked to patient safety issues, nurse satisfaction, nurse retention, as well as ineffective communication and collaboration (Fontaine & Gerardi, 2005; Institute for Safe Medication Practices (ISMP), 2004; Martin, 2008; Rosenstein & O‟Daniel, 2005). The Joint Commission has made recommendations to reduce the incidence of disruptive behaviors. Hospitals are being asked to take responsibility, hold physicians accountable for their actions, and address workplace intimidation (ISMP, 2004; Rosenstein & O‟Daniel, 2005; The Joint Commission, July 2008). The …

Perceptions And Evaluation Of An Urban Environment For Pedestrian Friendliness: A Case Study, Elizabeth H. Lee

Master's Theses

Public health is an increasingly important issue addressed from both environmental and public health sectors for the future development of urban environments. From a planning perspective, one possible solution is to increase walkability throughout the cities. Many assessment methods are being developed and administered to evaluate the quality of existing urban environments to promote walkable cities/communities. The results from using these methods provide policymakers and stakeholders with valuable information regarding the existing physical conditions of the environment. Although several US cities started to develop and refocus plans toward pedestrian-oriented policies approaches, results from this particular study determined that the quality …

New Mothers' Perceptions Of Their First Encounter With A Health Care Provider, Katherine Ure

Master's Theses

Since its genesis, health care has been developing and evolving to meet the needs of the population it serves. Hospital length of stay after childbirth has progressively decreased over the past 29 years initially in response to public pressure to reduce the medical aspect of childbirth. More recently, the decrease in length of stay has accelerated in response to cost-containment pressures (Eaton, 2001). This investigation examined new mothers’ perceptions of their maternal role attainment through their initial interaction with a health care provider. Ramona Mercer (1990) stated in Parents at Risk that there is a pressing need to facilitate early …

Master's Theses

Hospital-acquired pressure ulcers, a nursing care quality indicator, are becoming increasingly common in United States acute care facilities. In fiscal year 2007, the Centers for Medicare and Medicaid Services (CMS) recorded 257,412 “avoidable” Stage III and Stage IV pressure ulcers acquired in our nation’s hospitals on patients who were admitted to receive care for their primary diagnosis (CMS, 2007). Pressure ulcers are associated with pain and suffering, loss of function, increased length of stay, increased morbidity and mortality, and significant financial burden (Ayello & Lyder, 2008). In October 2008, the CMS discontinued payments for additional costs associated with pressure ulcers …

Bone Density Measurement Via Radiographic Calibration, Amber Jean Bowen

Master's Theses

Musculoskeletal injuries are the most common injuries sustained by athletes and military recruits and can result in decreased performance and lifelong disability. So common and costly are these injuries that the American Academy of Orthopedic Surgeons has provided guidelines for future research, including recommendations for the development of a large animal model of bone injury (USDA 2001). In human and veterinary medicine, digital radiography represents the primary diagnostic tool the physician uses to diagnose skeletal injury. Advances in digital radiography have provided the veterinarian with opportunities to make both simple and complex radiographic assessments. We investigated a simple quantitative measurement …

The Effect Of Recombinant Human Bone Morphogenetic Protein-2 On The Osseointegration Of Temporary Anchorage Devices, Eden E. Cruz

Master's Theses

Titanium has been widely used for dental implants, and in particular, roughened titanium surfaces have provided a means for increasing bone apposition and strengthening the implant-to-bone interface. Finding a way to further increase osseointegration is important because there is a significant clinical benefit to patients if a stable anchor can be established instead of anchoring orthodontic hardware to the molars. In this study, the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) on the ability of temporary anchorage devices (TADs) to osseointegrate was investigated. The temporary anchorage devices (TADs) used in this study were manufactured from commercially pure titanium and …

Osseointegration Of Temporary Anchorage Devices Using Recombinant Human Bone Morphogenetic Protein-2, Erin E. Cruz

Master's Theses

Over the past 5 years, the use of titanium implants as temporary anchorage devices (TADs) has become an important tool in clinical orthodontic practices. The use of TADs have provided orthodontists a way of moving teeth against fixed objects rather than against the surrounding teeth, which tend to counteract desired motion. At present, viable attachment of TADs involves direct insertion through gingival tissue and piercing of the bone. Surface modifications such as sandblasted and acid-etched treatment or bone morphogenetic protein surface treatment, however, can be applied to the TADs to promote enhanced osseointegration, thereby allowing the TADs to serve as …

Effects Of Reamer-Femoral Component Offset On Cement Mantle Penetration In Hip Resurfacing Arthroplasty, Mark Lloyd Paulick

Master's Theses

Hip resurfacing arthroplasty has changed the treatment of end stage arthritis without severe deformity for young, active adults. Presently, there are varying clinical approaches to implant design selection and cementation techniques.

An Investigation Of Humeral Stress Fractures In Racing Thoroughbreds Using A 3d Finite Element Model In Conjunction With A Bone Remodeling Algorithm, Ryan James Moore

Master's Theses

The humerus of a racing horse Thoroughbred is highly susceptible to stress fractures at a characteristic location as a result of cyclic loading. The propensity of a Thoroughbred to exhibit humeral fracture has made equines useful models in the epidemiology of stress fractures. In this study, a racing Thoroughbred humerus was simulated during training using a 3D finite element model in conjunction with a bone remodeling algorithm. Nine muscle forces and two contact forces were applied to the 3-dimensional finite element model, which contains four separate load cases representing fore-stance, mid-stance, aft-stance, and standing. Four different training programs were incorporated …

Morphological Development Of The Axial Skeletons Of Esox Lucius And Esox Masquinongy (Euteleostei: Esociforms), With Comparisons In Developmental And Mineralization Rates., Amanda Maria Burdi

Master's Theses

Developmental morphology of the axial skeleton of Esox lucius (i.e., northern pike and type species) and E. masquinongy (i.e., muskellunge) was investigated. More than 1,000 specimens were examined ranging in size from approximately 10 mm notochordal length (NL) post-hatching juveniles to over 80 mm standard length (SL) foraging sub-adults. Results show that regardless of individual variation, the relative sequence of bone formation and mineralization is consistent between the two species. This consistent developmental pattern enabled construction of an ontogenetic staging scheme of eight developmental stages, each characterized by one defining criterion. The first appearance in cartilage and/or first sign of …

Anti-Nogo-A Immunotherapy Facilitation Of Environmental Enrichment's Effects On Recovery From Stroke In The Aged Rat, Sarah Jane Hein

Master's Theses

Stroke and traumatic brain injury are devastating disorders that often lead to permanent neurologic deficits, with few available treatment options once injury has occurred. In previous work, Anti-Nogo-A immunotherapy has been shown to neutralize the neurite inhibitory protein, Nogo-A, and to promote neuronal plasticity and improve functional recovery after stroke in the rat. Furthermore, other reports have demonstrated that environmental enrichment improves functional recovery in rodents following stroke. Our previous work demonstrated that anti-Nogo-A immunotherapy also helps promote cortical plasticity in the rodent. In the current project, we examined two methods to promote recovery after brain injury, a stroke model …
