Technology Aiding In Neonatal Lung Developmental Care, Megan Kirk

Undergraduate Honors Theses

In this paper, old as well as new technological findings to decrease premature infant mortality are reviewed. This paper discusses fetal development throughout pregnancy from conception to full-term status as well as fetal lung development specifically from conception until full-term status. Several ideas to rapidly develop and mature fetal lungs are discussed such as mothers ingesting artificial surfactant supplements, either independently or coupled with antenatal corticosteroids, as well as intra-amniotic instillation prior to 28 weeks gestational. Drawbacks regarding these two are mentioned as well such as the fetus’s lungs not being mature enough to use the artificial surfactant leading into …

A Qualitative Analysis Of End-Of-Life Healthcare In Tennessee: Politics, Principles, And Perceptions, Erin Mauck

Electronic Theses and Dissertations

The unprecedented growth of the aging population in Tennessee is a significant demographic trend that highlights the necessity for healthcare policy that tackles end-of-life issues. This study examined the perceived quality of end-of-life healthcare in Tennessee, areas that are in need of improvement, policies that have the potential to influence improvements, and the role of politics in end-of-life healthcare policy. It also assessed the support for end-of-life healthcare policy that would advance quality of care and expand end-of-life choices for Tennesseans, while evaluating the policy-making process that legislators employ.

For this study, data were collected using semi-structured, in-depth interviews with …

Bdnf-Related Gene Expression Of Laser Capture Microdissected Glutamate Neurons From The Anterior Cingulate Cortex In Mouse Models Of Autism Spectrum Disorder, Misty Owens

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting social behaviors. ASD affects 1 in 59 children with males affected more frequently. ASD is postulated to result from excitatory and inhibitory neurotransmission imbalances. Brain-derived neurotrophic factor (BDNF) signaling affects ASD by influencing synaptogenesis, plasticity, and survival. Studying early in-utero neuropathological changes within ASD requires the use of animal models. Expression of BDNF-associated genes were analyzed within laser capture microdissected pyramidal neurons from the anterior cingulate cortex of male and female BTBR and valproic acid mouse models. No expression differences were found in any gene comparing the three groups. Gender comparisons …

Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb

Electronic Theses and Dissertations

Myeloid-derived suppressor cells (MDSCs) numbers increase significantly in sepsis and are associated with high mortality rates. These myeloid cell precursors promote immunosuppression, especially in the late (post sepsis) stage. However, the mechanisms that underlie MDSC expansion and programming are not completely understood. To investigate these mechanisms, we used a cecal-ligation and puncture (CLP) mouse model of polymicrobial sepsis that progresses from an early/acute proinflammatory phase to a late/chronic immunosuppressive phase. Previous studies in our laboratory showed that microRNA (miR)-21 and miR-181b elevate levels of the transcription factor nuclear factor 1 (NFI-A) that promotes MDSC expansion. We report here that miR-21 …

Evaluation Of An Innovative Transitional Care Clinic In An Interprofessional Teaching Practice, Mckenzie Calhoun Highsmith, Jesse Gilreath, Peter Bockhorst, Kathleen White, Beth Bailey

International Journal of Health Sciences Education

During transitions of care, great opportunity exists for miscommunication, poor care coordination, adverse events, medication errors and unnecessary healthcare utilization costing billions of dollars annually. An Interprofessional Transitions of Care (IPTC) clinic was developed utilizing a Family Medicine team that included physicians, nurses, a clinical social worker, and a clinical pharmacist. The purpose of this study was to determine if utilization of an IPTC clinic prevented hospital readmission, and to identify factors that predict most benefit from an interprofessional approach to transitions of care. A retrospective chart review of 1,001 patients was completed. A treatment group (TG) of 501 patients …

The Impact Of An International Interprofessional Experience On Perceptions Of Pharmacist-Physician Relationships, Miranda R. Andrus, Emily A. Powell, Katherine Moody, Taylor D. Steuber

International Journal of Health Sciences Education

Objective. To assess the impact of this international interprofessional learning experience on perceptions of pharmacist-physician relationships and interprofessional teams.

Methods. Medical and pharmacy students completed a one-week interprofessional medical mission experience in the Dominican Republic. Anonymous surveys were administered to 17 students before and after completion to measure perceptions of pharmacist-physician relationships and interprofessional teams. Responses were matched and changes in perceptions were analyzed using the Wilcoxon Signed Rank test. The SPICE-R2 instrument was administered after the experience to measure attitudes toward interprofessional teams.

Results. Of the 17 participants, 100% responded to all surveys. Significant improvements were seen in the …

A Protocol Driven Stroke Code's Impact On Door-To-Needle Times, Jesse Osborne

Electronic Theses and Dissertations

Tissue plasminogen activator (tPA) is most effective the faster it is able to be administered to a patient that has been affected by stroke. A Stroke Code is a strategy that acute care facilities implement to reduce the time from diagnosing a stroke to administering tPA. The purpose of this study was to determine if the initiation of a Stroke Code in an acute care hospital reduces the door-to-needle time for patients affected by a stroke. In particular, does a Stroke Code reduce door-to-needle times. The research was conducted using data from April 1, 2014 to December 31, 2014 (pre-Stroke …

The Effects Of Total Body Proton Irradiation On Mouse Myometrium, Lillith Bulawa

Undergraduate Honors Theses

The boundaries of human space exploration continue to expand with new technology and discoveries making it even more important to investigate the effects of space on biological systems. Although humans have explored space in small increments, reproductive studies must be conducted to determine if stable short- or long-term residences for humans can exist in space. This study explored the effects of whole-body proton radiation on uterine smooth muscle known as the myometrium. Two types of mice utilized in this study were C57BL/6 and B6.129S6Cybbtm1Din/J NOX2 knockout mice. C57BL/6 mice are standard laboratory mice that were used to represent the wildtype …

Polysubstance Exposure And Its Relationship To Pharmacological Treatment Characteristics, Parker Miller

Undergraduate Honors Theses

Neonatal Abstinence Syndrome (NAS) remains an ever-growing public health issue and a continued avenue for future research. The research question for this retrospective study was whether polysubstance exposure is related to the dose of medication the infant received or to the number of opioid-medications required to treat the infants’ withdrawal symptoms? The hypothesis for the retrospective study was there will be a significant relationship between polysubstance exposure and the dose of medication the infant received as well as the number of opioid-medications required to treat the infants’ withdrawal symptoms. A bivariate correlational indicated that there was not a significant association …

Management Of Type 1 Diabetes: A Family Affair, Emily Grubbs

Southeastern Council on Family Relations Conference

People who live with Type 1 diabetes (T1D) have to carefully self-administer insulin to keep blood glucose levels in a safe healthy range – a complex and demanding task (WHO, 2016). Social support has been found to alleviate diabetes-stress and increase management behaviors (Mackey et al., 2016). Social support from family members is especially advantageous, however currently no single family-based intervention has been established to show reliable improvements in T1D outcomes (Rosland et al., 2010). A review of the literature reveals that social support promoting autonomy is associated with the best T1D outcomes; social support that undermines autonomy is associated …
