The purpose of this project is to implement a nursing response checklist and neurological assessment guide to standardize the process of response to seizure events in the pediatric EMU.

Methods: This quality improvement (QI) project utilized a cohort study design. Standardized tools were placed in an accessible area outside patient rooms. Education was provided …

Implementation Of Skin-To-Skin Immediately Post C-Section: A Pilot Study, Miah Vernor

Dissertations

Skin-to-skin contact during the golden hour is a practice that has numerous health benefits following the delivery of a newborn. These benefits include a healthy transition to extrauterine state, initiation of breastfeeding, thermoregulation, and more. However, the mode of delivery affects how often this practice is done. Parents who deliver vaginally are routinely offered the opportunity to perform skin-to-skin immediately after delivery whereas birth parents who deliver by cesarean section are not always offered this same benefit due to various reasons. A quality improvement project was conducted on an 18-bed labor and delivery unit at a Midwest hospital. This project …

Implementation Of Postnatal Depression Screening: A Pilot Study, Mollie Gulino

Dissertations

Abstract

Background: Postpartum depression (PPD) is a prevalent problem among women during their childbearing years, affecting approximately 1 in 7 women. Alarmingly, about 50% of PPD cases go undiagnosed and untreated, contributing to poor maternal outcomes, including suicide, which is a leading cause of maternal mortality in the United States.

Issue: Despite its prevalence and severe consequences, PPD often goes unrecognized due to inconsistent screening practices. Current guidelines vary by organization and lack consistent, evidence-based criteria.

Objective: This pilot program aimed to implement universal PPD screening with a validated tool at the six-week postpartum follow-up visit. The goal was to …

Implementation Of Quantitative Blood Loss Following Cesarean Section Birth, Layna Victoria Schultz

Dissertations

Problems: Postpartum hemorrhage (PPH) is a significant problem due to potential harm and is a main contributor to maternal morbidity (ACOG, 2019). According to ACOG, of maternal deaths in the United States, 11% are caused by PPH and 54-93% of the deaths related to PPH could be prevented (ACOG, 2019). When institutions adopt quantitative blood loss (QBL) protocols for improved accuracy in blood measurement, PPH can be identified sooner, allowing for earlier intervention. Inaccurate estimation of obstetric blood loss by health care providers is a primary cause of delayed staff response to PPH (ACOG, 2019).

Methods: This quality improvement (QI) …

America Is Unprepared To Meet The Needs Of Its Growing Older Adult Population, Sierra Kaplan

Population Health Research Brief Series

In 2030, nearly 73 million Americans will be aged 65 years or older. As Americans continue to have fewer children than in the past, the number of older adults will outnumber children. Thus, fewer young adults will be around to support and care for the older adult population. Coupled with COVID-19 pandemic-driven disruptions to the healthcare industry, America’s health and aging care system is unprepared to support its large and growing older adult population. Over time, we will see increased health care scarcity and inequality in the distribution of elder care services, especially with continued healthcare worker shortages and drastic …

Persistent Interruption In Parvalbuminpositive Inhibitory Interneurons: Biophysical And Mathematical Mechanisms, Carol M. Upchurch, Christopher J. Knowlton, Simon Chamberland, Carmen C. Canavier

School of Graduate Studies Faculty Publications

Persistent activity in excitatory pyramidal cells (PYRs) is a putative mechanism for maintaining memory traces during working memory. We have recently demonstrated persistent interruption of firing in fastspiking parvalbumin-expressing interneurons (PV-INs), a phenomenon that could serve as a substrate for persistent activity in PYRs through disinhibition lasting hundreds of milliseconds. Here, we find that hippocampal CA1 PV-INs exhibit type 2 excitability, like striatal and neocortical PV-INs. Modeling and mathematical analysis showed that the slowly inactivating potassium current KV1 contributes to type 2 excitability, enables the multiple firing regimes observed experimentally in PV-INs, and provides a mechanism for robust persistent interruption …

Lefer

School of Graduate Studies Faculty Publications

Background and Purpose: Sodium glucose cotransporter 2 inhibitors (SGLT2i) have emerged as a potent therapy for heart failure with preserved ejection fraction (HFpEF). Hydrogen sulphide (H2S), a well-studied cardioprotective agent, could be beneficial in HFpEF. SGLT2i monotherapy and combination therapy involving an SGLT2i and H2S donor in two preclinical models of cardiometabolic HFpEF was investigated. Experimental Approach: Nine-week-old C57BL/6N mice received L-NAME and a 60% high fat diet for five weeks. Mice were then randomized to either control, SGLT2i monotherapy or SGLT2i and H2S donor, SG1002, for five additional weeks. Ten-week-old ZSF1 obese rats were randomized to control, SGLT2i or …

Canine Hepatocellular Carcinoma: Evaluating Pgam5 And Heterobilharzia Americana, Priscilla Devora

LSU Doctoral Dissertations

Hepatocellular carcinoma (HCC) is the most common primary liver cancer in humans and domestic dogs. Despite extensive research, the mechanisms that drive HCC carcinogenesis and perpetuate cancer survival are incompletely understood in both species. The work described herein focused on finding similarities between canine and human HCC, which could be harnessed to benefit humans and dogs with cancer. The first aim was to investigate the expression of phosphoglycerate mutase 5 (PGAM5) in canine HCC. Upregulation of PGAM5 is a negative prognostic indicator in human HCC. Using archival formalin-fixed paraffin-embedded samples, we found that PGAM5 was overexpressed in canine HCC ( …

School of Graduate Studies Faculty Publications

Regulator of G-protein signaling (RGS) proteins exhibit GTPase-accelerating protein activities to govern G-protein function. In the rice blast fungus Magnaporthe oryzae, there is a family of at least eight RGS and RGS-like proteins (MoRgs1 to MoRgs8), each exhibiting distinct or shared functions in the growth, appressorium formation, and pathogenicity. MoRgs3 recently emerged as one of the crucial regulators that senses intracellular oxidation during appressorium formation. To explore this unique regulatory mechanism of MoRgs3, we identified the nucleoside diphosphate kinase MoNdk1 that interacts with MoRgs3. MoNdk1 phosphorylates MoRgs3 under induced intracellular reactive oxygen species levels, and MoRgs3 phosphorylation is required for …

Electrocautery Wire Fenestration Prior To Thoracic Endovascular Aortic Repair To Optimize The Distal Landing Zone In Thoracic Aortic Dissections, Nicola Habash, Gaurang Joshi, Mohammed Ali, Michael Nooromid, Babak Abai

Department of Surgery Faculty Papers

Successful thoracic endovascular aortic repair (TEVAR) for type B aortic dissections (TBAD) relies on securing the stentgraft’s distal landing zone to prevent retrograde flow and false lumen pressurization. We describe a 60-year- old male with a TBAD undergoing TEVAR with electrocautery-wire fenestration of the dissection septum, providing a controlled method to enhance the distal landing zone for graft placement. Postoperatively, the patient experienced spinal cord ischemia, resolving with the placement of a lumbar drain and increasing mean arterial pressures. Follow-up imaging demonstrated a well-sealed repair without endoleaks. This case highlights the importance of surgical technique selection and postoperative monitoring for …

Where Are We Now With Oncolytic Viruses In Melanoma And Nonmelanoma Skin Malignancies?, George Nassief, Angela Anaeme, Karen Moussa, David Chen, George Ansstas

2020-Current year OA Pubs

Skin cancer prognosis has greatly improved recently due to the introduction of immune checkpoint inhibitors (ICIs). However, many patients with advanced skin cancer still experience immunotherapy resistance and disease progression during ICI treatment, thus calling for novel therapeutics which address this treatment gap. Talimogene laherparepvec (T-VEC) has gained popularity in recent years as a viable treatment option for patients with skin cancer. In preclinical studies, T-VEC demonstrated both a direct anti-tumor effect in injected lesions as well as a systemic immune-mediated effect in non-injected lesions, which could pose additional benefits when combined with ICI therapy. Following promising results from the …

2020-Current year OA Pubs

Children with sickle cell anemia (SCA) are at increased risk of stroke when compared with their age-based counterparts. The Stroke Prevention Trial in Sickle Cell Anemia (STOP) previously demonstrated that with the use of transcranial Doppler ultrasound (TCD; Sickle Stroke Screen) and chronic red cell transfusion, the risk of stroke is reduced by over 90%. The STOP criteria detailed the type and method of measurement required; the time-averaged mean maximum velocity (TAMMV). Unfortunately, it has been difficult to adhere to the appropriate TAMMV measurements. The objectives of this study were to assess the quality of TCD and transcranial Doppler imaging …

Defining Primary Refractory Large B-Cell Lymphoma, Allison M Bock, Brad S Kahl, Et Al.

2020-Current year OA Pubs

Patients with large B-cell lymphoma (LBCL) that fail to achieve a complete response (CR) or who relapse early after anthracycline-containing immunochemotherapy (IC) have a poor prognosis and are commonly considered to have "primary refractory disease." However, different definitions of primary refractory disease are used in the literature and clinical practice. In this study, we examined variation in the time to relapse used to define refractory status and association with survival outcomes in patients with primary refractory LBCL in a single-center prospective cohort with validation in an independent multicenter cohort. Patients with newly diagnosed LBCL were enrolled in the Molecular Epidemiological …

The Cns Relapse In T-Cell Lymphoma Index Predicts Cns Relapse In Patients With T- And Nk-Cell Lymphomas, Rahul S Bhansali, Neha Mehta-Shah, Et Al.

2020-Current year OA Pubs

Little is known about risk factors for central nervous system (CNS) relapse in mature T-cell and natural killer cell neoplasms (MTNKNs). We aimed to describe the clinical epidemiology of CNS relapse in patients with MTNKN and developed the CNS relapse In T-cell lymphoma Index (CITI) to predict patients at the highest risk of CNS relapse. We reviewed data from 135 patients with MTNKN and CNS relapse from 19 North American institutions. After exclusion of leukemic and most cutaneous forms of MTNKNs, patients were pooled with non-CNS relapse control patients from a single institution to create a CNS relapse-enriched training set. …

Background

While individuals who were separated from their biological family and placed into the care of the state during childhood (out-of-home care) are more prone to developing selected adverse health problems in adulthood, their risk of cardiovascular disease is uncertain. Our aim was to explore this association by pooling published and unpublished results from prospective cohort studies.

Methods

We used two approaches to identifying relevant data on childhood care and adult cardiovascular disease (PROSPERO registration CRD42021254665). First, to locate published studies, we searched PubMed (Medline) until November 2023. Second, with the objective of identifying unpublished studies with the potential to …

The communication component of the Enhanced Recovery after Surgery protocol is a foundation for improved patient outcomes and pain management. The problem that was identified in this Doctor of Nursing Practice project was lack of staff education during the perioperative period related to nurse-patient communications regarding pain management. Using the analysis, design, development, implementation, and evaluation model of instructional design, the purpose of this DNP project was to plan, implement, and evaluate a staff education …

A Fungal Metabolic Regulator Underlies Infectious Synergism During Candida Albicans-Staphylococcus Aureus Intra-Abdominal Co-Infection, Saikat Paul, Olivia A. Todd, Kara R. Eichelberger, Christine Tkaczyk, Bret R. Sellman, Mairi C. Noverr, James E. Cassat, Paul L. Fidel, Brian M. Peters

School of Dentistry Faculty Publications

Candida albicans and Staphylococcus aureus are two commonly associated pathogens that cause nosocomial infections with high morbidity and mortality. Our prior and current work using a murine model of polymicrobial intra-abdominal infection (IAI) demonstrates that synergistic lethality is driven by Candida-induced upregulation of functional S. aureus α-toxin leading to polymicrobial sepsis and organ damage. In order to determine the candidal effector(s) mediating enhanced virulence, an unbiased screen of C. albicans transcription factor mutants was undertaken revealing that zcf13Δ/Δ fails to drive augmented α-toxin or lethal synergism during co-infection. A combination of transcriptional and phenotypic profiling approaches shows that ZCF13 regulates …

Hyperactive Ras signalling is found in most cancers. Ras proteins are only active in membrane nanoclusters, which are therefore potential drug targets. We previously showed that the nanocluster scaffold galectin-1 (Gal1) enhances H-Ras nanoclustering via direct interaction with the Ras binding domain (RBD) of Raf. Here, we establish that the B-Raf preference of Gal1 emerges from the divergence of the Raf RBDs at their proposed Gal1-binding interface. We then identify the L5UR peptide, which disrupts this interaction by binding with low micromolar affinity to the B- and C-Raf-RBDs. Its 23-mer core fragment is sufficient to interfere with H-Ras nanoclustering, modulate …

Multiple myeloma (MM) is a hematologic malignancy characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM patients with aggressive progression have poor survival, emphasizing the urgent need for identifying new therapeutic targets. Here, we show that the leukocyte immunoglobulin-like receptor B1 (LILRB1), a transmembrane receptor conducting negative immune response, is a top-ranked gene associated with poor prognosis in MM patients. LILRB1 deficiency inhibits MM progression in vivo by enhancing the ferroptosis of MM cells. Mechanistic studies reveal that LILRB1 forms a complex with the low-density lipoprotein receptor (LDLR) and LDLR adapter protein 1 (LDLRAP1) to facilitate LDL/cholesterol …
