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

Care, Control, And The Racial Regulation Of Black Women’S Reproduction In American Medicine, Rheya K. Wilk
Care, Control, And The Racial Regulation Of Black Women’S Reproduction In American Medicine, Rheya K. Wilk
Honors Thesis
Black women in the United States continue to experience disproportionately high rates of maternal mortality, negative reproductive healthcare experiences, and documented disparities in medical treatment. From slavery through the twenty-first century, American medicine has repeatedly positioned Black women’s reproduction as a site of regulation, rather than care, making medical mistrust among Black women a rational response to a long history of institutional conflict embedded in American medicine. Drawing on medical history and bioethical analysis, this thesis traces reproductive abuse across distinct, yet connected, eras. Beginning with antebellum gynecological experimentation on enslaved women, it demonstrates how racialized assumptions about pain and …

Values-Based Clinical Ethics: A New Model Of Health And Ethics Consultation For Patients Suffering In Extremis, Adam Trainer
Values-Based Clinical Ethics: A New Model Of Health And Ethics Consultation For Patients Suffering In Extremis, Adam Trainer
Electronic Theses and Dissertations
This dissertation argues that contemporary clinical ethics is inadequately equipped to support patients suffering in extremis because it relies on an insufficiently discriminating account of health and a constrained model of moral reasoning. Drawing on Bernard Lonergan, it reconceives health as an emergent, multi-layered, heuristic notion shaped by biological, psychological, social, and existential goods. On that basis, it critiques principlism’s global applicability thesis and the undergirding claim that its principles form part of the common morality, arguing that this justificatory structure is philosophically insufficient and practically limited for clinical ethics in cases marked by profound suffering, moral plurality, and normative …

BACKGROUND: Systemic inflammation is hypothesized to contribute to post-traumatic stress disorder (PTSD) vulnerability. Few studies have examined inflammation shortly after trauma as a predictor of later PTSD symptoms. We examined whether inflammation from the emergency department (ED) post-trauma is associated with PTSD symptom severity over the following 6 months.
METHODS: Our sample included 742 AURORA participants, a longitudinal cohort of patients in 29 EDs across the United States after a traumatic stressor, followed up to 6 months. Plasma cytokines were assessed from a study blood draw in the ED: an inflammatory index (standardized sum of generally pro-inflammatory markers interleukin [IL]-6, …
