Tocilizumab Prophylaxis Following Axicabtagene Ciloleucel In Relapsed Or Refractory Large B-Cell Lymphoma, Frederick L Locke, Nancy L Bartlett, Et Al.

2020-Current year OA Pubs

Axicabtagene ciloleucel (axi-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved in patients with relapsed/refractory (R/R) large B-cell lymphoma (LBCL). Most patients treated with axi-cel experience cytokine release syndrome (CRS) and/or adverse neurologic events (NEs). To explore potential approaches for reducing CAR T-cell-related toxicities with axi-cel, several safety expansion cohorts were added to the pivotal ZUMA-1 trial. ZUMA-1 Cohort 3 was an exploratory safety cohort that investigated the use of the IL-6 receptor-blocking antibody tocilizumab and anticonvulsant levetiracetam as prophylaxis against CRS and NEs in patients treated with axi-cel. Patients with R/R LBCL were enrolled in Cohort …

Implementing Bedside Shift Report In The Home Health Care Pediatric Setting, Ruth Elena Ramos-Ardila

Electronic Theses and Dissertations

Developing and maintaining good communication is central in nursing because the goal is to achieve the best outcomes for the patient. In the past, written handover reports have been the standard way nurses communicate with each other, especially in the hospital and in home-based practice. Despite this rationale, this approach has considerable weaknesses: its high risk of mistakes and misunderstanding could negatively influence patient outcomes. In light of these concerns, this project examines the role of bedside shift reports in pediatric home care and the patient readmission rate. This project employed a quantitative, cross-sectional research approach involving 32 pediatric home …

Impact Of Diabetes Self-Management Education On Hemoglobin A1c Levels In The Rural Patient Population, Barbara Adomakomensah Sarpong

Electronic Theses and Dissertations

The global prevalence of type 2 diabetes is one of the greatest health threats in society, especially in the rural population. Rural healthcare data analysis has proved a need for type 2 diabetes control education. Despite the existence of helpful diabetes control interventions, rural diabetes patients still struggle to maintain healthy behaviors, with about 60% of the patients recording hemoglobin A1c levels above 9. Many suffer severe conditions (e.g., stroke, kidney failure, and heart attacks) because of poor management of the condition. The project examined the impact of diabetes self-management education on hemoglobin A1c levels in the rural patient population. …

Transgender Education In School Nursing To Decrease Stigma And Promote Self-Efficacy, Brandy Shannon-Loyola

Electronic Theses and Dissertations

This Doctor of Nursing Practice project evaluated whether transgender education provided to school nurses and healthcare technicians decreased stigma and promoted self-efficacy. Concerns that transgender individuals have voiced were that they felt healthcare professionals could not effectively care for transgender patients, which may be due to personal or religious beliefs or lack of knowledge concerning the lesbian, gay, bisexual, transgender, and queer community. Participants included credentialed school nurses and healthcare technicians in secondary education settings. The method consisted of a presurvey, education in the form of a handout, followed by a postsurvey to determine if education was successful. The Wilcoxon …

Clinical Validation Of A Cell-Free Dna Fragmentome Assay For Augmentation Of Lung Cancer Early Detection, Peter J Mazzone, David Gierada, Et Al.

2020-Current year OA Pubs

Lung cancer screening via annual low-dose computed tomography has poor adoption. We conducted a prospective case-control study among 958 individuals eligible for lung cancer screening to develop a blood-based lung cancer detection test that when positive is followed by a low-dose computed tomography. Changes in genome-wide cell-free DNA fragmentation profiles (fragmentomes) in peripheral blood reflected genomic and chromatin characteristics of lung cancer. We applied machine learning to fragmentome features to identify individuals who were more or less likely to have lung cancer. We trained the classifier using 576 cases and controls from study samples and validated it in a held-out …

Distinct Patterns Of Smooth Muscle Phenotypic Modulation In Thoracic And Abdominal Aortic Aneurysms, Chien-Jung Lin, Campbell Keating, Robyn Roth, Yasar Caliskan, Mustafa Nazzal, Vernat Exil, Richard Dipaolo, Divya Ratan Verma, Kishore Harjai, Mohamed Zayed, Chieh-Yu Lin, Robert P Mecham, Ajay K Jain

2020-Current year OA Pubs

Thoracic and abdominal aortic aneurysms (TAAs and AAAs, respectively) share morphological features but have distinct clinical and hereditary characteristics. Studies using bulk RNA comparisons revealed distinct patterns of gene expression in human TAA and AAA tissues. However, given the summative nature of bulk RNA studies, these findings represent the totality of gene expression without regards to the differences in cellular composition. Single-cell RNA sequencing provides an opportunity to interrogate cell-type-specific transcriptomes. Single cell RNA sequencing datasets from mouse TAA (GSE153534) and AAA (GSE164678 and GSE152583) with respective controls were obtained from the Gene Expression Omnibus. Bioinformatic analysis was performed with …

Multiple myeloma (MM) is the cancer of plasma cells within the bone marrow and remains incurable. Tumor-associated macrophages (TAMs) within the tumor microenvironment often display a pro-tumor phenotype and correlate with tumor proliferation, survival, and therapy resistance. IL-10 is a key immunosuppressive cytokine that leads to recruitment and development of TAMs. In this study, we investigated the role of IL-10 in MM TAM development as well as the therapeutic application of IL-10/IL-10R/STAT3 signaling inhibition. We demonstrated that IL-10 is overexpressed in MM BM and mediates M2-like polarization of TAMs in patient BM, 3D co-cultures in vitro, and mouse models. In …

Correlative analyses included the HER2DX genomic tool, multiomic evaluations of HER2 heterogeneity, and predictors of thrombocytopenia. …

The Emerging Role Of Long Noncoding Rnas In Sorafenib Resistance Within Hepatocellular Carcinoma, Puneet Vij, Mohammad Shabir Hussain, Sanjaya Satapathy, Everardo Cobos, Manish Kumar Tripathi

School of Medicine Publications

Hepatocellular carcinoma (HCC), a liver cancer originating from hepatocytes, is a major health concern and among the most common malignancies worldwide. Sorafenib, approved by the U.S. F.D.A., is the primary first-line treatment for patients with advanced HCC. While the preferred first-line systemic regimen for HCC is immunotherapy with Atezolizumab plus bevacizumab or Tremelimumab-actl + durvalumab, Sorafenib is still an alternative recommended regimen. While some patients with advanced HCC may benefit from Sorafenib treatment, most eventually develop resistance, leading to poor prognosis. Long noncoding RNAs (lncRNAs) have been found to play a critical role in tumorigenesis and the development of HCC, …

Unmasking A Silent Threat: Celiac Disease Revealing Coronary Artery Disease – A Case Report [Desenmascarando Una Amenaza Silenciosa: Enfermedad Celíaca Revelando Enfermedad Arterial Coronaria – Reporte De Caso], Jose Fernando Vargas-Ledo, Maria Eugenia Torres-Perez, Mario Trujillo-Acosta, Monica Olvera-Lopez

School of Medicine Publications

Celiac disease (CD) is an autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals, marked by inflammation and the production of anti-tissue transglutaminase antibodies. Although CD patients often have lower body mass indexes and LDL levels, systemic inflammation can lead to endothelial dysfunction and accelerated atherosclerosis, potentially increasing the risk of coronary artery disease (CAD). We present a case of a 46-year-old female with CD who developed multivessel CAD, ultimately requiring coronary artery bypass grafting. This case highlights the significant cardiovascular risk associated with CD, suggesting that inflammation and genetic factors may contribute to atherosclerosis. While the precise mechanisms …

Peripheral nerve damage can cause debilitating symptoms ranging from numbness and pain to sensory loss and atrophy. To uncover the underlying mechanisms of peripheral nerve injury, our research aims to develop a relationship between biomechanical peripheral nerve damage and function through finite element modeling. A noncontact, ex vivo electrophysiology chamber, capable of axially stretching explanted nerves while recording electrical signals, was used to investigate peripheral nerve injury. Successive stretch trials were run on eight sciatic nerves (four females and four males) excised from Sprague-Dawley rats. Nerves were stretched until 50% compound action potential (CAP) amplitude reduction was obtained. A constitutive …

The Adolescent Brain and Cognitive Development (ABCD) project is the largest study of adolescent brain development. ABCD longitudinally tracks 11,868 participants aged 9-10 years from 21 sites using standardized protocols for multi-site MRI data collection and analysis. While the multi-site and multi-scanner study design enhances the robustness and generalizability of analysis results, it may also introduce nonbiological variances including scanner-related variations, subject motion, and deviations from protocols. ABCD imaging data were collected biennially within a period of ongoing maturation in cortical thickness and integrity of cerebral white matter. These changes can bias the classical test-retest methodologies, such as intraclass correlation …

Pdgf-Bb Overexpression In P53 Null Oligodendrocyte Progenitors Increases H3k27me3 And Induces Transcriptional Changes Which Favor Proliferation, Dennis Huang, Angeliki Mela, Natarajan V Bhanu, Benjamin A Garcia, Peter Canoll, Patrizia Casaccia

2020-Current year OA Pubs

Proneural gliomas are brain tumors characterized by enrichment of oligodendrocyte progenitor cell (OPC) transcripts and genetic alterations. In this study we sought to identify transcriptional and epigenetic differences between OPCs with Trp53 deletion and PDGF-BB overexpression (BB-p53n) and those carrying only p53 deletion (p53n). In culture, the BB-p53n OPCs display growth characteristics more similar to glioma cells than p53n OPCs. When injected in mouse brains, BB-p53n OPC form tumors, while the p53n OPCs do not. Unbiased histone proteomics and transcriptomic analysis on these OPC populations identified higher levels of the histone H3K27me3 mark and lower levels of the histone H4K20me3. …

Can Acetabular Dysplasia Be Measured On Axial Ct? A Measurement For Trauma Surgeons, Ravi R Agrawal, Eric R Barnard, Helena F Barber, Anna N Miller

2020-Current year OA Pubs

BACKGROUND: Acetabular dysplasia has been theorized as a risk factor instability amongst common acetabular fractures, such as posterior wall (PW) fractures. However, common radiographic measurements often cannot be acquired in trauma patients. We evaluated axial computed tomography (CT) scans to identify novel, easily-obtained measurements that correlate with acetabular dysplasia for use in surgical indications and planning.

METHODS: Patients with known acetabular dysplasia undergoing elective periacetabular osteotomy were selected. A different group of patients without pelvic ring or acetabular fractures from an institutional trauma registry were selected as a comparison group. Standard indices of dysplasia were collected, such as center-edge angle …

Impact Of Obstructive Sleep Apnea On Masticatory Muscle Function, Diana Russo, Luis Eduardo Almeida, Vincenzo Ronsivalle, Marco Cicciù, Gabriele Cervino, Maria Maddalena Marrapodi, Giuseppe Minervini

School of Dentistry Faculty Research and Publications

Obstructive sleep apnea (OSA) is a common and potentially serious sleep disorder characterized by repetitive episodes of complete or partial upper airway obstruction during sleep. These obstructions result in a reduction or cessation of airflow, leading to oxygen desaturation, and disruptions in sleep patterns.1,2 Common symptoms of OSA include loud snoring, gasping or choking during sleep, excessive daytime sleepiness, morning headaches, and irritability. Obstructive sleep apnea is often associated with other medical conditions, such as obesity, hypertension, cardiovascular disease, and diabetes. Diagnosis typically involves polysomnography to assess the frequency and severity of apneic episodes.
