Cortical Bone Density And Thickness Assessment Of Intraradicular Sites In Adolescent Patients Using Cbct Imaging, Sara Endo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The indications for the use of cone beam computed tomography (CBCT) in orthodontics has grown since it was first introduced and dentists are discovering new ways that 3D images enhance diagnosis and treatment planning. Evaluating bone quality and quantity can be measured as bone density and thickness in CBCT imaging and is helpful for temporary anchorage device (TAD) placement in orthodontic treatment. TADs rely on primary stability and are commonly used in orthodontic treatment to increase anchorage and expand the limit that nonsurgical orthodontics can provide.

Objectives: This study aims to assess the bone thickness and density at different …

Correlation Between Maxillary Transverse Width, Alveolar Housing Width And Palatal Bone Thickness: A Cbct Retrospective Study, Eric G. Hollensbe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background:

Accurate assessment of transverse maxillary dimensions and surrounding bone morphology is critical for safe orthodontic treatment planning. Orthodontic expansion should remain within the biological limits of the alveolar housing and palatal bone to prevent adverse periodontal outcomes, including dehiscence, fenestration, and gingival recession. Standard diagnostic methods, such as dental casts and two-dimensional radiographs, offer limited information about the three-dimensional anatomy that restricts orthodontic tooth movement. Cone-beam computed tomography (CBCT) provides detailed evaluation of skeletal dimensions and cortical bone boundaries. This study aimed to examine the relationships among maxillary transverse width, alveolar housing thickness, and palatal thickness using CBCT imaging. …

The Impact Of Youth Sport On Occupational Balance: A Survey Study, Sean Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

Youth sport has been highly researched, exploring both positive and negative health impacts (Adetunji & Akendutire, 2017; Brengtsson et al., 2025; Conway, 2024; Hoffman et al., 2022). Despite the high prevalence of youth sport participation, and variability of health-related outcomes, there has been no research regarding the impact youth sport participation has on occupational balance, an occupational therapy concept that has been linked with overall health and well-being (Park et al., 2021). A mixed-methods, cross-sectional survey study was used to gain better insights into the impact youth sport participation may have on occupational balance. A sample size of 466 Nevada …

Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones

Seton Hall University Dissertations and Theses (ETDs)

This qualitative study examined how insured non-English- and English-speaking Hispanic adults perceive the role of health insurance in the management of chronic disease. Chronic conditions remain a leading cause of morbidity in the United States, and although prior research suggests that insurance coverage improves access to care, it does not always enhance how individuals understand or utilize support for chronic disease management. Limited research has explored how individuals with chronic conditions interpret the role of insurance in their daily self-management practices, particularly among Hispanic populations. Guided by Andersen’s Behavioral Model of Health Services Use, this study explored how contextual, enabling, …

Quality Improvement (Qi) Project Aimed At Reducing Unnecessary Antibiotic Usage Among Older Adult Patients By Addressing Inappropriate Antibiotic Prescribing In Primary And Long-Term Care Settings, Pamela M. Thomas

Seton Hall University Dissertations and Theses (ETDs)

Antibiotic overuse among older adults remains a significant patient safety and public health concern. Recent national data indicate that approximately 30%–50% of outpatient antibiotic prescriptions may be unnecessary, particularly for viral or self-limiting conditions (Chua et al., 2021). Antimicrobial resistance has been associated with more than 1.27 million deaths globally (Murray et al., 2022). This quality improvement project evaluated a multifaceted antimicrobial stewardship intervention in primary and long-term care settings. Baseline review of 167 antibiotic cases revealed 37.1% were inappropriate or questionable, and 28.7% lacked adequate diagnostic documentation. The intervention incorporated provider education, electronic health record decision-support tools, audit and …

Impact Of Travel Time To Health Facilities On Perinatal Outcomes: A Systematic Review With Narrative Synthesis And Meta-Analysis, Sanam Roder-Dewan, Marwa Ramadan, Paul Ouma, Alexander Manu, Emelda A. Okiro, Natalie Strobel, Bibian N. Robert, Emily Odipo, Peter M. Macharia, Anthony Danso-Appiah, David C. Goodman, Queen Dube, Gagan Gupta, Hema Magge, Karen Edmond

Research outputs 2022 to 2026

Background: Evidence-based global guidance on safe travel time for small or sick newborns who require transfer to health facilities after birth is lacking. A two-hour threshold is frequently cited in low- and middle-income countries (LMICs), while 30 minutes is commonly used in high-income countries (HICs). Although these thresholds are widely referenced, their empirical basis and consistency across levels of newborn care and journey types have not been systematically examined. This study synthesises the evidence linking travel time and perinatal outcomes. Methods: We conducted a systematic review with narrative synthesis and meta-analysis to assess the impact of travel time or distance …

Gut Dysbiosis And Microbial Metabolites In Atopic Dermatitis: Implications For Immune Regulation Along Gut-Skin Axis, Khushbakhat Alia, Hira Khan, Hamna Muzaffar, Nighat Perveen, Sara Alrashedi, Yusra Al Dhaheri, Yasir Waheed, Mohammed Tauqeer Alam, Muhammad Naseem, Khalid Muhammad

All Works

Atopic dermatitis (AD) is a multifactorial skin disorder characterized by immune dysregulation, impaired epidermal barrier, and strong microbial imbalance. Although genetic susceptibility and environmental triggers are established AD drivers, growing evidence highlights the gut skin axis as an important but underexplored AD pathogenesis factor. Gut microbiota dysbiosis, loss of short-chain fatty acid (SCFA)-producing bacteria, and altered metabolite profiles, such as tryptophan derivatives and secondary bile acids, have been linked to systemic immune imbalance and skin inflammation. However, the precise mechanism by which gut microbial alterations influence cutaneous immunity remains unclear. This review synthesizes recent advances from clinical and experimental studies …

Quantification Of Sarm1 Nadase Activity In Human Peripheral Blood Mononuclear Cells, Lila F Dabill, Ivana R Shen, Jennifer M Brazill, Alicia Neiner, Yo Sasaki, Erica L Scheller

2020-Current year OA Pubs

SARM1 (sterile α and TIR motif-containing protein-1) is an NADase enzyme that serves as the central executioner of Wallerian axon degeneration. Given this, SARM1 is of high interest as a candidate therapeutic target, and SARM1 inhibitors are currently in clinical trials for treatment of neurodegeneration. Beyond neuroscience, emerging studies reveal that SARM1 may also drive aspects of bone fragility, liver pathology, adipose expansion, and insulin resistance in metabolic disease. However, we lack methods to quantify SARM1 activation in humans to better define patients at high risk of SARM1-mediated tissue damage. Unlike neurons, peripheral blood mononuclear cells (PBMCs) represent an easily …

2020-Current year OA Pubs

BACKGROUND: Many neuropsychiatric conditions share overlapping features underpinned by shared genetics. In this study, we examined the co-aggregation of sub-threshold variation in neuropsychiatric phenotypes in biological parents of autistic children to provide insights into the intergenerational transmission of genetic liability for autism.

METHODS: Autistic, neuropsychiatric (i.e., anxiety, depression, ADHD), and cognitive traits were characterized in biological parents of children enrolled in a longitudinal developmental study: 189 families of autistic children and 100 families with no autistic children were included. Families were further characterized as having only one (simplex) or more than one (multiplex) autistic child. Maternal and paternal traits were …

Neurodiversity Among Nurses: Consequences For Wellbeing And Burnout, Megan Pohlmann

WUSM Theses and Dissertations – All Programs

Background/Introduction – Current research highlights three critical aspects of nurse wellbeing: the subjective personal perspective, multifaceted complexity, and variation across individuals. A particular gap in past research is a lack of understanding of how neurodivergence may impact nurses’ workplace wellbeing. Neurodiversity is the variation in human minds and neurocognitive functioning, and neurodivergence is the divergence from what society would consider the norm. Like wellbeing, it is difficult to capture, recognize, and define, which causes confusion among neurodivergent individuals and employers alike. With up to 20% of individuals displaying neurodivergent traits in the workplace, it is important to recognize that those …

Improving The Assessment And Treatment Of People With Low Back Pain, Kayla Krueger

WUSM Theses and Dissertations – All Programs

Low back pain (LBP) is a significant and continually growing public health problem. While some people recover from an initial episode, a proportion will develop chronic or recurrent LBP that limits their ability to perform daily functional activities. The variable and often function-limiting course of LBP underscores the clear need for improved methods of assessment and treatment. One way to improve the assessment and treatment of LBP is to develop a more comprehensive understanding of factors that contribute to LBP. In this dissertation, we investigated two categories of factors that may contribute to a person’s LBP: (1) spinal movement impairments …
