Meta-Regression: Prognostic Models As Objective Predictors Of Mortality Among Icu Cancer Patients, Sheila Donnell

Nursing Theses and Dissertations

Cancer patients admitted to the intensive care unit (ICU) may be experiencing complications of disease or treatment-related effects. While acute complications related to disease and/or its therapeutic management vary in severity, the approach to ICU-centered care is complicated by actual versus perceived risks of poor outcomes. Prognostic models that inform clinical judgment of nurses and physicians may prove helpful in this population. The Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II) and Sequential Organ Failure Assessment (SOFA) are ICU-based models predicting 30-day mortality among the general ICU population. Although studies have been …

Breast Cancer Patient Preparedness For Transition To Survivorship: Individualized Survivorship Care Plans, Kimberly Beringer

Master's Projects and Capstones

Purpose. For breast cancer survivors, after-effects of surgery, radiation and chemotherapy can be substantial, and recurrence is a concern requiring constant surveillance. National healthcare organizations have promulgated guidelines that include providing individualized survivorship care plans (SCP’s). At a northern California oncology department, SCP’s will be prepared for breast cancer patients and delivered in-person by the oncology nurse navigator (ONN).

Method. The author worked with the ONN to develop the format and content requirements for the SCP’s. The ONN prepared individualized plans for patients and scheduled in-person appointments to deliver the SCP’s. A feedback survey to assess preliminary impact was then …

Managing Variant Discrepancy In Hereditary Cancer: Clinical Practice, Barriers, And Desired Resources, Ellen Zirkelbach

Dissertations & Theses (Open Access)

Variants are changes in the DNA whose phenotypic effects may or may not be definitively understood. Because variant interpretation is a complex process, sources sometimes disagree on the classification of a variant, which is called a variant discrepancy. This study aimed to determine the practice of genetic counselors regarding variant discrepancies and to identify the barriers to counseling a variant discrepancy in hereditary cancer genetic testing. This investigation was unique because it was the first to address variant discrepancies from a clinical point of view. An electronic survey was sent to genetic counselors in the NSGC Cancer Special Interest Group. …

Dox Inducible Idh2 R140q Expression In Stem Cells Results In Cell Death, Opposite Of Cancerous Overgrowth, Reuben Hogan

Undergraduate Research Symposium Posters

Mutations in isocitrate dehydrogenase (IDH) 1 or 2 are found in about 23% of acute myeloid leukemia (AML) samples and about 90% of gliomas. Mutations result in neomorphic function of the IDH enzyme that yields the novel molecule 2-hydroxyglutarate (2HG) instead of alpha-ketoglutarate (aKG). 2HG is known to be associated with hypermethylation of DNA and histones, a phenotype seen in AML. Our lab intends to study the mechanism by which hypermethylation is achieved and how this mechanism relates to the onset of cancer. In this experiment, we utilized a line of H9 stem cells which we had developed. These cells …

Thyroid Hormone Receptor Ss (Trß) Regulation Of Runt-Related Transcription Factor 2 (Runx2) In Thyroid Tumorigenesis: Determination Of The Trß Nuclear Protein Complexes That Associate With The Runx2 Gene., Thomas Howland Taber

Graduate College Dissertations and Theses

Thyroid Tumorigenesis is typically a well understood process, with well delineated oncogenic factors. Follicular and papillary thyroid cancers are typically survivable, with 5-year survival rates being >95% for Stage I-III of both cancer types. Anaplastic thyroid cancer, in contrast, lacks this prognosis, and is the most lethal of all endocrine-related cancers. The median survival time after a diagnosis is generally between 6-8 months, with a 5-year survival rate of <10%. Current treatment for anaplastic thyroid cancers routinely meet roadblocks, as resistance is quickly developed. Even non-discriminatory kinase inactivators, such as sorafenib, which are generally considered a drug of last resort, are unable to effect survival rates. As such, there is a clear need for further investigation of the causes of anaplastic thyroid cancer mechanisms.

Previous work in the Carr lab revealed a novel regulatory pathway of an oncogene that is associated with several other endocrine-related cancers, as well as other non-endocrine-related cancers. Specifically, the Runt-related …

Using Tcr Transgenic, Gp100 Reactive T Cells And Checkpoint Inhibition To Target Lymphangioleimyomatosis, Christian Ankney

Master's Theses

Lymphangioleiomyomatosis (LAM) is a low-grade neoplastic disease affecting primarily women. It is characterized by cystic lung disease as well as renal and retroperitoneal tumors called angiomyolipomas and lymphangiomas. Tumor cells have smooth muscle features as well as neuroendocrine cell surface markers, and the disease can be diagnosed by HMB45 staining of tumor cells. We questioned whether expression of melanocytic antigens, specifically gp100, creates an opportunity to treat LAM by adoptive T cell transfer. LAM lung lesions demonstrate poor immune surveillance, therefore adoptive T cell transfer could offer benefits in this disease.

A link was made between melanoma and depigmenting vitiligo …

The Lived Experience Of Intersectionality Among African American Women With Breast Cancer, Teri D. Armour Burton

Dissertations

African American women (AAW) continue to have breast cancer mortality rates that are 42% higher than White women (De Santis et al., 2015). Researchers suggest that an epistemological approach that integrates the biomedical and feminist models would be more effective in addressing health disparities. The concept of intersectionality, which grew out of the Black feminist movement, provides a lens in which to view the lived experiences of AAW with breast cancer. The intersectionality paradigm attempts to address the marginalized, oppressive, intersecting social existence of AAW through the examination of identity, social class, and power.

This qualitative study applied a descriptive …

Using Technologies To Support The Social And Academic Engagement Of Young People With Cancer, Owen Michael Donovan

Legacy Theses & Dissertations (2009 - 2024)

Situated in the larger questions of how to support the educational engagement and positive psychosocial development of young people with cancer, the purpose of this exploratory study was to address gaps in the literature and build understanding of how young people use digital and Internet-connected technologies in ways that support their social and academic engagement. Through a multiple case-design, I examined the school-based and everyday (outside of school) technology uses of five young people. This study found that the cancer experience changed or reframed a young person’s motivational engagement with school. Doing well academically was a sign of a normalcy …

The Role Of Progesterone Receptor Membrane Component 1 In Receptor Trafficking And Disease, Kaia K. Hampton

Theses and Dissertations--Pharmacology and Nutritional Sciences

The progesterone receptor membrane component 1 (PGRMC1) is a multifunctional protein with a heme-binding domain that promotes cellular signaling via receptor trafficking, and is essential for some elements of tumor growth and metastasis. PGRMC1 is upregulated in breast, colon, lung and thyroid tumors. We expanded the analysis of PGRMC1 in the clinical setting, and report the first analysis of PGRMC1 in human oral cavity and ovarian tumors and found PGRMC1 to correlate with lung and ovarian cancer patient survival. Furthermore, we discovered a specific role for PGRMC1 in cancer stem cell viability. PGRMC1 directly associates with the epidermal growth factor …
