A Standardized Unit Based Process For Obtaining Heart Failure Patient Weights, Lesli E. Teed

Master's Projects

Introduction: A CNL student-led process improvement process improvement project was proposed to help improve the accuracy of Heart Failure patient weights on a geriatric specialty unit. Cardiology voiced a preference for patients to be weighed using electronic standing scales rather than in-bed scales to improve accuracy. A literature review revealed that in-bed scale weights were less accurate due to inconsistencies in zeroing the bed prior to obtaining the weight, not removing excess patient care equipment and bed linens, and not ensuring that the patient was wearing a minimal amount of clothing.

Methods: Electronic standing scales were purchased, current practice state …

Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht

Electronic Theses and Dissertations

Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …

Neuroscience Faculty Publications

Excessive brain iron negatively affects working memory and related processes but the impact of cortical iron on task-relevant, cortical brain networks is unknown. We hypothesized that high cortical iron concentration may disrupt functional circuitry within cortical networks supporting working memory performance. Fifty-five healthy older adults completed an N-Back working memory paradigm while functional magnetic resonance imaging (fMRI) was performed. Participants also underwent quantitative susceptibility mapping (QSM) imaging for assessment of non-heme brain iron concentration. Additionally, pseudo continuous arterial spin labeling scans were obtained to control for potential contributions of cerebral blood volume and structural brain images were used to control …

Epigenetic Regulation Of Prostate Cancer, Ruixin Wang, Xiaoqi Liu

Toxicology and Cancer Biology Faculty Publications

Prostate cancer is (PCa) the second leading cause of cancer death in males in the United State, with 174,650 new cases and 31,620 deaths estimated in 2019. It has been documented that epigenetic deregulation such as histone modification and DNA methylation contributes to PCa initiation and progression. EZH2 (enhancer of zeste homolog 2), the catalytic subunit of the Polycomb Repressive Complex (PRC2) responsible for H3K27me3 and gene repression, has been identified as a promising target in PCa. In addition, overexpression of other epigenetic regulators such as DNA methyltransferases (DNMT) is also observed in PCa. These epigenetic regulators undergo extensive post-translational …

The patient was splinted in plantar flexion and had prompt orthopedic referral with MRI that verified Achilles tear.

What's Going On With The Spine? Evaluation Of Alternative Sensorimotor Degeneration Post-Stroke, Sravani Mannuru, Sarvani Uppati, Kelsey Baker

MEDI 9331 Scholarly Activities Clinical Years

Stroke is a leading cause of long-term disability in the United States. Previous research has shown a strong correlation between damage to the corticospinal tract (CST) and motor deficits in post-stroke patients. However, recent research suggests that other sensorimotor pathways (rubrospinal tract, medial reticulospinal tract) are damaged after stroke and may also contribute to motor dysfunction. Here, we will review current research suggesting that alternate sensorimotor pathways are involved in post-stroke motor dysfunction and outline possible avenues for future research.

Inflammatory Myopathies: Update On Diagnosis, Pathogenesis And Therapies, And Covid-19-Related Implications., Marinos C. Dalakas

Department of Neurology Faculty Papers

The inflammatory myopathies constitute a heterogeneous group of acquired myopathies that have in common the presence of endomysial inflammation. Based on steadily evolved clinical, histological and immunopathological features and some autoantibody associations, these disorders can now be classified in five characteristic subsets: Dermatomyositis (DM) Polymyositis (PM), Necrotizing Autoimmune Myositis (NAM), Anti-synthetase syndrome-overlap myositis (Anti-SS-OM), and Inclusion-Body-Myositis (IBM). Each inflammatory myopathy subset has distinct immunopathogenesis, prognosis and response to immunotherapies, necessitating the need to correctly identify each subtype from the outset to avoid disease mimics and proceed to early therapy initiation. The review presents the main clinicopathologic characteristics of each subset …
