Novel Titanium Cages For Minimally Invasive Lateral Lumbar Interbody Fusion: First Assessment Of Subsidence, Paul R. Krafft, Brooks Osburn, Andrew C. Vivas, Gautam Rao, Puya Alikhani

Neurosurgery and Brain Repair Faculty Publications

Introduction: Implant subsidence is a potential complication of spinal interbody fusion and may negatively affect patients subjected to procedures relying on indirect decompression such as minimally invasive transpsoas lateral lumbar interbody fusion (LLIF). The porous architecture of a recently developed titanium intervertebral cage maximizes bone-to-implant contact and minimizes stress shielding in laboratory experiments; however, its subsidence rate in patients has not yet been evaluated. The goal of this current study was to evaluate implant subsidence in patients subjected to LLIF.

Methods: Our institutional review board-approved single-center experience included 29 patients who underwent 30 minimally invasive LLIF from July 2017 to …

Mesenchymal Stem Cell Therapy Alleviates The Neuroinflammation Associated With Acquired Brain Injury, Brooke Bonsack, Sydney Corey, Alex Shear, Matt Heyck, Blaise Cozene, Nadia Sadanandan, Henry Zhang, Bella Gonzales-Portillo, Michael Sheyner, Cesar V. Borlongan

Neurosurgery and Brain Repair Faculty Publications

Ischemic stroke and traumatic brain injury (TBI) comprise two particularly prevalent and costly examples of acquired brain injury (ABI). Following stroke or TBI, primary cell death and secondary cell death closely model disease progression and worsen outcomes. Mounting evidence indicates that long-term neuroinflammation extensively exacerbates the secondary deterioration of brain structure and function. Due to their immunomodulatory and regenerative properties, mesenchymal stem cell transplants have emerged as a promising approach to treating this facet of stroke and TBI pathology. In this review, we summarize the classification of cell death in ABI and discuss the prominent role of inflammation. We then …

Diffuse Intrasinusoidal Hepatic Metastasis From Breast Cancer Presenting As Liver Failure: Effective And Rapid Treatment With Weekly Low-Dose Adriamycin, Thanh-Phuong N. Afiat, Timothy N. Hembree, Erin A. Dean, Cyrillo Araujo, Luis R. Pena, Marilin Rosa, Hyo S. Han, Kaitlin Hendrix, Asha Ramsakal

Oncologic Sciences Faculty Publications

Background: Hepatic metastasis is well known in breast cancer. Approximately 12–20% of breast cancer patients will develop liver metastasis, which usually presents as discrete mass lesions. Rarely, metastatic spread can be so diffuse that it is unidentifiable on imaging but can progress to fulminant hepatic failure. Our case report suggests that clinicians need to have a high index of suspicion when patients present with rapidly decompensating liver failure in the absence of discrete radiologic hepatic lesions, and that weekly Adriamycin should be considered as a first-line therapeutic option.

Case Report: A 28-year-old African American woman with a history of locally …

Electronic Theses and Dissertations, 2020-2023

Preterm birth in the United States is the leading cause of infant morbidity and mortality. The United States spends more per capita on healthcare than any other nation in the world, and still perinatal outcomes are disappointing when compared to other industrialized nations. Research and current clinical practice guidelines support the use of early and consistent prenatal care to lower risks for preterm birth, by acting as a key mechanism to monitor pregnancy and provide timely and appropriate interventions. Significant research has been completed to identify causative factors that lead to preterm birth. Overall, this literature has not had a …

Single Cell Forensic Genomics - Dna Profiling Of Micromanipulated Single Spermatozoa, Haley Hardin

Electronic Theses and Dissertations, 2020-2023

Current U.S. National guidelines allow for the collection of sexual assault evidence up to 5 days after the incidence occurs. In these cases, the ability to obtain an autosomal STR (aSTR) profile of the male donor in these cases diminishes as the time interval increases. This inability to recover an aSTR profile from the semen donor is not due to a complete lack of sperm cells, as studies have frequently shown that sperm persists in the vaginal canal or cervix up to 10 days post coitus. Thus, the inability to recover an aSTR profile of the sperm donor is likely …

Binegative Minority Stress, Psychological Processes, And Disordered Alcohol Use: Disparities Among Sexual Minority Womxn, Kinsie Jean Dunham

Graduate Student Theses, Dissertations, & Professional Papers

Sexual minority womxn (i.e., woman-identified persons) tend to report more harmful alcohol use and more negative alcohol use outcomes than heterosexual women—a pattern not consistently observed in man-identified populations. Further, bisexually-oriented, hereafter called nonexclusively-oriented, womxn (NOW) report more negative alcohol use outcomes and meet criteria for alcohol use disorder at higher rates than both lesbians and heterosexual women (or exclusively-oriented womxn; EOW). These disparities require further investigation to explicate the antecedents and mechanisms impacting alcohol use for this at-risk population. This project examines the incremental negative effects of binegativity as a specific minority stressor and antecedent of disordered alcohol use. …

Linking Health Behavior Theory And Interventions To Increase Human Papillomavirus Vaccine Uptake, Gretchen Elizabeth Neal

Graduate Student Theses, Dissertations, & Professional Papers

Human papillomavirus (HPV) is the most common sexually transmitted disease in adults in the United States (US). Persistent HPV infection can cause several cancers, including cervical, oropharyngeal, and anal cancer. To prevent these cancers, the U.S. Advisory Committee on Immunization Practices recommends that all adolescents start the HPV vaccine series at ages 11-12 years. Despite the safety and efficacy of available HPV vaccines, vaccine uptake rates remain lower than public health goals. In the US, only 51.1% of eligible adolescents have completed the vaccine series, a rate lower than the Healthy People 2020 goal of 80% coverage for series completion. …
