Mechanical Properties Of Canine Patella-Ligament-Tibia Segment., Jeffery Biskup, Andy Freeman, W Camisa, J Innes, Michael Conzemius

Jeffery Biskup, DVM, DACVS

OBJECTIVE: To test the ex vivo mechanical properties of canine patella-ligament-tibia (PLT) segment and establish the relationship between donor size and PLT dimensions to the mechanical properties of PLT grafts.STUDY DESIGN: Ex vivo mechanical testing study. SAMPLE POPULATION: Canine PLT segments (n = 21 dogs; 42 PLT). METHODS:Morphometric measurements of PLT segments were taken from computed tomography (CT) images and compared with results obtained using calipers. PLT were tested to failure at a rate of 100% length/s. Mechanical properties and failure mode were recorded. RESULTS: PLT width and thickness (P < .001 for both) measured by calipers were significantly lower than those taken from CT images. Thirty-five (83%) specimens failed by avulsion fracture from the patella, 1 failed mid-ligament, and 6 failed by tibial fracture. Dog weight and PLT length had the strongest Pearson's r value when correlated with load at failure (r = 0.73, 0.81, respectively). CONCLUSION:Dog weight and PLT length were the best predictors of load at failure. PLT failure load of dogs weighing >25 kg were similar to those reported for ...

The Effects Of Perinatal Methamphetamine Use On Maternal And Child Outcomes: Implications For Education Among Bsn Nursing Students, Tina Nguyen

Honors Theses

The implications of methamphetamine use are vast and prevalent in the U.S. This epidemic is also well recognized in Tennessee and in Hamilton County. The number of men and women that continue to use methamphetamine speaks to the importance of this issue. Among these individuals, pregnant women comprise a significant portion of female methamphetamine users across the United States. The potential complications that can arise for not only a mother but also her child due to maternal methamphetamine use pose a much more significant issue. The detrimental effects that a child can experience as a result of maternal methamphetamine ...


The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey Dec 2017

The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey

Senior Theses and Capstone Projects

Type 1 Diabetics have various ways of managing their diabetes that have been studied for their effectiveness. Pregnancy in the Type 1 Diabetic has been understudied. It is known that Diabetics in general have poorer pregnancy outcomes because of poor glycemic control. This coupled with the fact that the body needs 3-4 times more insulin as pregnancy comes to an end makes managing blood glucose levels challenging for diabetics (Lowdermilk, 2016, p. 689). For the Type 1 Diabetic, there are two main ways to control diabetes: multiple daily injections using at least two type of insulin and continuous subcutaneous insulin ...

The Fight Against Breast Cancer: A Policy And Programmatic Approach, Nandi Robinson

Master's Projects and Capstones

Abstract

Breast cancer continues to remain a significant health issue for women. Previously thought to only occur among postmenopausal women, breast cancer has impacted women of different ages; and rates of breast cancer have various impacts among different ethnic groups. For women living in a toxic environment, many of them have become the new wave of breast cancer cases. Screening and detection have succeeded in decreasing mortality rates. However, more research is needed in finding an efficient method of treatment. In the effort to assist in the fight against breast cancer through a policy and programmatic angle, I am fulfilling ...

A patient with germline von Hippel-Lindau (VHL) gene alteration and history of multiple tumors present with classical paraneoplastic syndrome (PNS) associated with renal cell carcinoma (RCC). She underwent open nephron sparing surgery with resolution of symptoms. She remained without recurrence of RCC for the initial 2 years of her follow-up. To the best of our knowledge, this case represents the first in which PNS was specifically resolved using a partial nephrectomy in a patient with VHL. This case report provides initial evidence for the potential role of nephron sparing surgery in the management of paraneoplastic symptoms associated with hereditary RCC.

Skin cancer is a major public health concern, and tanning remains a modifiable risk factor. Multidimensional influences, including psychosocial, individual, environmental, and policy-related factors, create the milieu for individuals to engage in tanning. Parents and physicians can modify the behavior of teens and young adults using strategies based on harm reduction. Environmental and policy-related factors similar to those used to limit smoking by restricting access of minors to cigarettes in the United States in the 20th century need to be created. Federal regulations can restrict direct advertising and the excise tax can be increased to a prohibitive amount. Social networking ...

Retention In Health: Improving Hiv Retention Within The Sf Community Health Network, Miguel A. Ibarra

Master's Projects and Capstones

Previous work on HIV retention improvement has focused on improving access to care for communities who are either at-risk of falling out of care or who have difficulty engaging in medical care for the first time due to socio-cultural barriers. The San Francisco Department of Public Health (SFDPH), with the support of Project PRIDE, a CDC three-year demonstration project geared towards supporting health departments in implementing public health strategies to reduce new HIV infections within the men who have sex with men (MSM) and transgender communities, is seeking to improve HIV patient retention throughout the San Francisco Community Health Network ...


Occlusion Effects In Various Testing Conditions Using Insert Earphones, Amanda M. Desantolo Jun 2017

Occlusion Effects In Various Testing Conditions Using Insert Earphones, Amanda M. Desantolo

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

The occlusion effect is a well-known phenomenon that can affect audiological testing. Sound energy that would typically escape is trapped when covering the ear(s) and reflected back toward the inner ear. This increases the intensity of the sound, resulting in the “appearance” of a more sensitive threshold. Many aspects of the occlusion effect have been well researched and understood, however there are still aspects that warrant further investigation, such as the degree of occlusion with insert earphones when using partial versus full insertion and whether one or both of the ears are occluded. A within-subject design (n=5) was ...

Recreational Music Exposure And Music-Induced Hearing Loss: A Systematic Literature Review, Carolyn Lindenbaum

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

Legislation regarding occupational noise exposure is the result of a long period of interest and research; more recently, the effects of recreational noise are receiving increasing attention. Various sources of recreational noise and music exposure have become more widespread among the general public, increasing research in this source of potential risk. The proliferation of personal music players that are easily available and accessible to children and adults has contributed to the spread of leisure music exposure. Leisure music exposure is also common in the attendance of concerts and clubs/discos, and bars/pubs. The present systematic literature review focused exclusively ...


Development Of 90th Percentile Norms For Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study, Iris Wertheimer Jun 2017

Development Of 90th Percentile Norms For Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study, Iris Wertheimer

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

The acoustic reflex threshold has been well established in the literature as an involuntary bilateral contraction of the stapedius muscle in response to loud transient sounds. Additionally, the clinical utility of the acoustic reflex threshold has been established as it allows for the differential diagnosis of many different conductive, cochlear and retrocochlear pathologies. Gelfand, Schwander and Silman (1990) have established and validated 90th percentile normative data for use with the contralateral acoustic reflex threshold. Much of the literature on the acoustic reflex threshold has focused on the contralateral acoustic reflex threshold; however, surveys have found that many clinicians are ...

A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels ...

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies ...


Deconstructing Rape Culture Through An Exploration Of Consent, Desire, And Pleasure, Yael Rosenstock Jun 2017

Deconstructing Rape Culture Through An Exploration Of Consent, Desire, And Pleasure, Yael Rosenstock

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

Desire and pleasure based education combats the notion of passive consent by prioritizing positive experiences for all members involved in sexual activities. A focus on desire requires that we learn and listen to our partner’s needs and respect their boundaries. It questions a patriarchal script of sex in which male pleasure, specifically when penetrating a partner, is the critical part of the sexual act. Sex motivated by mutual desire and pleasure forces us to step back and learn, not just about our partners but ourselves, so that we may communicate our wants and needs effectively.

To understand how to ...

"Marie Manje La Pom Nan." Examining The Cognitive Process Of Restructuring And Advantage Selection In The Definite Article System In Haitian Creole Among U.S. Born Heritage Speakers Of Haitian Creole, Marie-Michelle Monéreau-Merry

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

The distributional patterns of heritage speakers’ reanalyzed first language are often grammatically divergent from native speakers. Irrespective of the heritage language, there is converging evidence that the cognitive process of reanalysis of heritage languages is often evident in less salient properties of the language, such as inflectional morphology (Polinsky & Kagan, 2007). Therefore, Haitian Creole (HC) is a candidate for restructuring. In this investigation we compared the morphophonological patterns of the definite article system at the production and perception level between two groups of early learners of Haitian Creole (i.e. native speakers vs. United States (US) born heritage speakers).

The ...

Affordable And Accessible Hearing Healthcare Interventions In The United States: A Literature Review And Prospective Analysis, Garrett Thompson

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

Age-related hearing loss is a significant public health concern with serious and far-reaching consequences including: social isolation, depression, faster cognitive decline, and increased risk of falls. Hearing loss is a widespread condition, it is in fact a leading cause of disability among older people. Hearing aids, the primary intervention for adults with hearing loss, are costly and inaccessible to many patients who need them. Among other reasons, these factors have led to a low uptake rate among the adult population; only one in seven adults who could benefit from wearing hearing aids utilizes them. Given the status quo of high ...

Mechanistic Mathematical Models: An Underused Platform For Hpv Research, Marc Ryser, Patti Gravitt, Evan R. Myers

Global Health Faculty Publications

Health economic modeling has become an invaluable methodology for the design and evaluation of clinical and public health interventions against the human papillomavirus (HPV) and associated diseases. At the same time, relatively little attention has been paid to a different yet complementary class of models, namely that of mechanistic mathematical models. The primary focus of mechanistic mathematical models is to better understand the intricate biologic mechanisms and dynamics of disease. Inspired by a long and successful history of mechanistic modeling in other biomedical fields, we highlight several areas of HPV research where mechanistic models have the potential to advance the ...

Psychology Faculty Publications and Presentations

Zohar and Luria’s (2005) safety climate (SC) scale, measuring organization- and group- level SC each with 16 items, is widely used in research and practice. To improve the utility of the SC scale, we shortened the original full-length SC scales. Item response theory (IRT) analysis was conducted using a sample of 29,179 frontline workers from various industries. Based on graded response models, we shortened the original scales in two ways: (1) selecting items with above-average discriminating ability (i.e. offering more than 6.25% of the original total scale information), resulting in 8-item organization-level and 11-item group-level SC ...
