Maldi-Msi Identification Of Tissue-Level N-Glycomic And Proteomic Molecular Biomarkers Of Aggressive Prostate Cancer, Jordan Paige Hartig

MUSC Theses and Dissertations

Prostate Cancer (PCa) poses a significant clinical challenge, characterized by debates on screening efficacy and continuous issues with distinguishing aggressive from non-aggressive tumors. Despite treatment advancements, poor patient outcome at late stages and clinical overtreatment of indolent disease emphasizes the urgent need for markers of PCa aggression. Aberrant glycosylation and extracellular matrix (ECM) remodeling are two complex molecular processes necessary for PCa progression, highlighting a novel area for biomarker discovery. Leveraging formalin-fixed paraffin-embedded tissues, tissue microarrays (TMAs), and matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI), distinct N-glycan and ECM profiles are identified. Elevated bisecting, multi-antennary, and fucosylated N-glycans indicate early …

Research Frameworks: Critical Components For Reporting Qualitative Health Care Research, Ann Z. George

Journal of Patient-Centered Research and Reviews

Qualitative health care research can provide insights into health care practices that quantitative studies cannot. However, the potential of qualitative research to improve health care is undermined by reporting that does not explain or justify the research questions and design. The vital role of research frameworks for designing and conducting quality research is widely accepted, but despite many articles and books on the topic, confusion persists about what constitutes an adequate underpinning framework, what to call it, and how to use one. This editorial clarifies some of the terminology and reinforces why research frameworks are essential for good-quality reporting of …

Adult Development And Associated Health Risks, Elizabeth C. Halloran

Journal of Patient-Centered Research and Reviews

Much has been learned about adult development in recent decades. Adults go through stages of development (emerging adulthood, young adulthood, middle adulthood, post-retirement, and very old age) with certain challenges at each stage. Viewing patients through a developmental lens is part of providing patient-centered care. Knowing the prominent issues, stressors, and risks at each stage of development is important in understanding patients. This knowledge can help customize medical advice to patients regarding obesity, disability, sleep, substance use, relationships, and age-related declines. This paper summarizes an updated view of adult development and discusses its relevance to health risks and patient-centered care …

UNLABELLED: Cancer stem cells (CSC) play a critical role in metastasis, relapse, and therapy resistance in colorectal cancer. While characterization of the normal lineage of cell development in the intestine has led to the identification of many genes involved in the induction and maintenance of pluripotency, recent studies suggest significant heterogeneity in CSC populations. Moreover, while many canonical colorectal cancer CSC marker genes have been identified, the ability to use these classical markers to annotate stemness at the single-cell level is limited. In this study, we performed single-cell RNA sequencing on a cohort of 6 primary colon, 9 liver metastatic …

Faculty, Staff and Student Publications

Appendiceal adenocarcinoma (AA) is unique from other gastrointestinal malignancies in that it almost exclusively metastasizes to the peritoneal cavity. However, few studies have investigated the molecular interaction of the peritoneal microenvironment and AA. Here, we use a multi-omics approach with orthotopic and flank-implanted patient-derived xenografts (PDX) to study the effect of the peritoneal microenvironment on AA. AA tumors implanted in the peritoneal microenvironment tended to grow faster and displayed greater nuclear expression of Ki-67 relative to the same tumors implanted in the flank. Comparing the tumor-specific transcriptome (excluding stromal transcription), the peritoneal microenvironment relatively upregulated genes related to proliferation, including …

Faculty, Staff and Student Publications

Metastatic disease remains the leading cause of death due to cancer, yet the mechanism(s) of metastasis and its timely detection remain to be elucidated. Neutrophil elastase (NE), a serine protease secreted by neutrophils, is a crucial mediator of chronic inflammation and tumor progression. In this study, we used the PyMT model (NE+/+ and NE-/-) of breast cancer to interrogate the tumor-intrinsic and -extrinsic mechanisms by which NE can promote metastasis. Our results showed that genetic ablation of NE significantly reduced lung metastasis and improved metastasis-free survival. RNA-sequencing analysis of primary tumors indicated differential regulation of tumor-intrinsic actin cytoskeleton signaling pathways …

Respiratory Therapists' Attitudes On Patient Safety And The Use Of Workarounds: A Phenomenological Study, Lee Wisdom

Graduate Theses, Dissertations, and Capstones

Respiratory therapists (RTs) provide cardiopulmonary care and share the essential responsibility of keeping patients safe throughout their healthcare journey. RTs care for patients in various settings and manage mechanical ventilation (life-support), artificial airways, and attend emergencies such as cardiac arrests and other urgent clinical care matters (American Association for Respiratory Care [AARC], n.d.-b). As such, RTs may be exposed to opportunities in their day-to-day routines that influence patient safety. Currently, the literature is limited regarding RTs’ safety attitudes and the use of workarounds in respiratory care in the United States (U.S.).

Faculty, Staff and Students Publications

Colonoscopy is accurate but inefficient for colorectal cancer (CRC) prevention due to the low (~ 7 to 8%) prevalence of target lesions, advanced adenomas. We leveraged rectal mucosa to identify patients who harbor CRC field carcinogenesis by evaluating chromatin 3D architecture. Supranucleosomal disordered chromatin chains (~ 5 to 20 nm, ~1 kbp) fold into chromatin packing domains (~ 100 to 200 nm, ~ 100 to 1000 kbp). In turn, the fractal-like conformation of DNA within chromatin domains and the folding of the genome into packing domains has been shown to influence multiple facets of gene transcription, including the transcriptional plasticity …
