The final scholarly project proposal is to implement oral care education for nurses in an intensive care unit (ICU). The proposal aims to create a guideline for an investigator to implement oral care recommendations for mechanically ventilated patients in order to reduce ventilator-associated pneumonia (VAP). The proposal consists of obtaining VAP data and oral care charting data for the unit studied, steps for providing oral care education, and analysis recommendations. Oral care involves swabbing the patient’s mouth every two hours with a swab and mouthwash. Oral care education would include handouts and direct teaching. The proposal aims to increase oral …

Mesoscopic Analysis Of Fatigue Damage Development In Asphalt Mixture Based On Modified Burgers Contact Algorithm In Discrete Element Modeling

Faculty, Staff and Student Publications

This study is aimed at examining the mesoscopic mechanical response and crack development characteristics of asphalt mixtures using the three-dimensional discrete element approach via particle flow code (PFC). The material is considered an assembly of three phases of aggregate, mortar, and voids, for which three types of contact are identified and described using a modified Burgers model allowing for bond failure and crack formation at contact. The laboratory splitting test is conducted to determine the contact parameters and to provide the basis for selecting three different load levels used in the indirect tensile fatigue test and simulation. The reliability of …

An Ultra Energy-Efficient Hardware Platform For Neuromorphic Computing Enabled By 2d-Tmd Tunnel-Fets, Mike Davies

Faculty, Staff and Student Publications

Brain-like energy-efficient computing has remained elusive for neuromorphic (NM) circuits and hardware platform implementations despite decades of research. In this work we reveal the opportunity to significantly improve the energy efficiency of digital neuromorphic hardware by introducing NM circuits employing two-dimensional (2D) transition metal dichalcogenide (TMD) layered channel material-based tunnel-field-effect transistors (TFETs). Our novel leaky-integrate-fire (LIF) based digital NM circuit along with its Hebbian learning circuitry operates at a wide range of supply voltages, frequencies, and activity factors, enabling two orders of magnitude higher energy-efficient computing that is difficult to achieve with conventional material and/or device platforms, specifically the silicon-based …

Latent Tb Treatment Regimens In 2023: Wetmore Tb Clinic In New Orleans, Amy Wolfe, Priyanka Jadhav, Amber May, Shandrica Seymour, Angela Blanchard, Juzar Ali

School of Medicine Faculty Publications

The USPSTF has updated Latent TB Infection (LTBI) screening and treatment recommendations in 2023; describing treatment courses, side effects and benefits associated with each regimen. Overall, rifampin-containing shortened regimens are the preferred modality for LTBI treatment. A recent study in 2023 evaluated adherence and tolerance of the isoniazid(INH) + rifapentine(RPT), or “3HP” regimen and identified patient groups that may be at higher risk for non-completion of this regimen. It emphasized the need for targeted education at the beginning of treatment, to avoid early discontinuation. Our experience in New Orleans demonstrated that the 3HP is well-tolerated, with higher completion rates than …

Surface-Functionalized Magnetic Silica-Malachite Tricomposite (Fe–M–Si Tricomposite): A Promising Adsorbent For The Removal Of Cypermethrin, Xiaobo Chen

Faculty, Staff and Student Publications

Surface charges of catalysts have important influences on the thermodynamics and kinetics of electrochemical reactions. Herein, we develop a modified version of the grand-canonical potential kinetics (GCP-K) method based on density functional theory (DFT) calculations to explore the effect of surface charges on reaction thermodynamics and kinetics. Using the hydrogen evolution reaction (HER) on the Pt(111) surface as an example, we show how to track the change of surface charge in a reaction and how to analyze its influence on the kinetics. Grand-canonical calculations demonstrate that the optimum hydrogen adsorption energy on Pt under the standard hydrogen electrode condition (SHE) …

First-Principles Study Of Electronic Properties Of Substitutionally Doped Monolayer Snp3

Faculty, Staff and Student Publications

Isovalent doping offers a method to enhance the thermoelectric properties of semiconductors, yet its influence on the phonon structure and propagation is often overlooked. Here, we take CdX (X=Te, Se) compounds as an example to study the role of isovalent doping in thermoelectrics by first-principles calculations in combination with the Boltzmann transport theory. The electronic and phononic properties of Cd8Se8, Cd8Se7Te, Cd8Te8, and Cd8Te7Se are compared. The results suggest that isovalent doping with CdX significantly improves the thermoelectric performance. Due to the similar properties of Se and Te atoms, the electronic properties remain unaffected. Moreover, doping enhances anharmonic phonon scattering, …

Sub-Saharan Africa’S Handling Of Covid-19 Pandemic: Rwanda Versus Tanzania, Luke D. Baumel

Honors Undergraduate Conference

How has the Covid-19 outbreak in early 2020 and the pandemic that followed been handled in Sub-Saharan Africa? What was done well and what was done poorly and why? What are the implications of the way it was handled? These questions and more are answered throughout this paper, using Rwanda as an example of a Sub-Saharan African country who handled it relatively well and neighboring Tanzania as an example of a Sub-Saharan African country that mishandled the outbreak and pandemic. In early 2021, most Sub-Saharan African countries had been afflicted by Covid-19 at a relatively lower rate than many Western …

Changing The Way Providers Order Blood Return To Intensive Care Patients, Chloe Morris

Spring Showcase for Research and Creative Inquiry

Patients with anemia and other conditions resulting in loss of blood often come with orders to return wasted blood to them. While using typical blood draw practices, patients are placed at an increased risk of infection when their blood is exposed to the outside world. My question is, will using a closed system decrease the instances of infection in patients who receive their waste blood after draws? By utilizing a waste syringe attached to the IV line, nurses can avoid detaching and reattaching syringes to collect and give back the patient's blood. Patients who are already at an increased risk …

Detection And Management Of Post Intensive Care Syndrome, Ann Tomy

Nursing | Student Research Posters

Post Intensive Care Syndrome (PICS) is a collection of symptoms that more than half of patients who survive a critical illness experience after discharge.Those symptoms include weakness, fatigue, sleep disturbances, cognitive dysfunction, post-traumatic stress disorder, mental health conditions, and a lack of effective coping strategies. PICS can significantly impact an individual's quality of life, complicating the recovery process and posing challenges for reintegration into daily activities and societal roles. The etiology of PICS is multifactorial, with the severity and duration of the illness, the nature of medical interventions in the ICU, and the pre-existing health condition of the patient all …

Continuous Renal Replacement Therapy For Lithium Toxicity: A Worthy Treatment To Avoid Intradialytic Hypotension And Vasopressors., Pooya Zardoost, Zachary Buckman, Joseph Weaver, Sidney Elston, Alex Prouty, Ryan Stuart, Henry L Wehrum

Ambulatory and Primary Care Articles

While intermittent hemodialysis (HD) is the most efficient method of removing lithium in patients with lithium toxicity, continuous renal replacement therapy is an acceptable alternative in the setting of intradialytic hypotension. This form of dialysis can reduce the need for vasopressors during HD, which increases mortality.

Robust Capital Cost Optimization Of Generation And Multitimescale Storage Requirements For A 100% Renewable Australian Electricity Grid, Derek Abbott

Faculty, Staff and Student Publications

Transitioning from a fossil-fuel-dependent economy to one based on renewable energy requires significant investment and technological advancement. While wind and solar technologies provide lower cost electricity, enhanced energy storage and transmission infrastructure come at a cost for managing renewable intermittency. Energy storage systems vary in characteristics and costs, and future grids will incorporate multiple technologies, yet the optimal combination of storage technologies and the role of interconnectors in alleviating storage needs are not widely explored. This study focuses on optimal generation-storage capacity requirements to elucidate associated investments. We propose a multitimescale storage solution consisting of three storage categories and an …

Aorto-Superior Vena Cava Fistula Secondary To Ascending Aortic Dissection, Talal Al-Assil, Aiden Michael Van Loo, Bakri Kaakeh, Bashar Al Jayyousi, Rania Esteitie

Journal of Shock and Hemodynamics

Aortic fistulas are a rare condition that can be fatal if not detected early. They can occur spontaneously or after trauma or vascular procedures. The most common aortic fistulas occur with the esophagus, intestines, atrium, and bronchi. Aorto-superior vena cava (SVC) fistulas are exceedingly rare finding. We present a patient with a dissected aortic pseudoaneurysm complicated by an aorto-SVC fistula, leading to left-to-right shunting. This caused increased pulmonary blood flow, left ventricular volume overload, and eventual high-output heart failure. This is a unique case of an aorto-SVC fistula as a complication of subacute/chronic ascending aortic dissection in a patient who …

Evidence-Based Practice For Terminal Extubation: A Guideline Development For Critical Care, Heather Marica

Student Scholarly Projects

Practice Problem: In the critical care unit it was identified that providers utilized various practices in managing patients who were to be terminally extubated (TE). The variations in TE practice resulted in healthcare providers engaging in the TE process feeling unsure of the care they were providing and questioning if best practice measures were being implemented.

PICOT: The PICOT question guiding this project was: “In acute care adult patients who are to be TE (P), how does the development of an evidence-based TE guideline (I) compared to current TE practices (C) improve critical care healthcare workers perception and ability to …

To meet the needs of this population, a standardized novel critical care curriculum targeting third- and fourth-year medical students was developed. Objectives: We hypothesized that the institution of such a curriculum is feasible and will provide an increased understanding of the underlying critical care principles within this learner population. Methods: We developed a 2-month-long critical care curriculum (February–April) and carried out the course twice from 2022–2023. Our pilot study deployed this curriculum …

A True Bloody Emergency: An Unusual Case Of Thrombotic Thrombocytopenic Purpura, Joshua M. Ninan

Research Symposium

Background: Thrombotic thrombocytopenic purpura (TTP) is a primary thrombotic microangiopathy that is classically characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA). Although rare with an annual incidence of 3.7 cases per one million adults, it is considered a true hematological emergency due to its fatality rate of almost 100% if appropriate treatment is not initiated immediately. This makes it vitally important to identify and treat patients with TTP, a task that becomes unusually challenging in the absence of the disorder’s other characteristically diagnostic clinical features such as mucosal bleeding, fever, or presence of schistocytes.

Case Presentation: A 30-year-old gentleman with …

Painting A Landscape Of Acute Care Nurse Scientist Work, Teresa Rangel

Providence Nursing Research Conference 2023 – Present

Background: Hospitals are increasingly hiring nurse scientists, motivated in part by nursing excellence designations such as Magnet. Magnet designation requires at least three, nurse-led, Institutional Review Board-approved research studies to be conducted in the hospital every four years and for nurses to be actively implementing evidence-based practice (EBP) projects using research evidence. However, clinical nurses often lack the specialized knowledge and training necessary to engage in well-designed research or EBP. Nurse scientists are PhD-prepared individuals with expertise to mentor clinical nurses to navigate the rigor and complexity of creating, implementing, analyzing, and disseminating research and EBP projects. Yet, due …

Acute Care Staff Interactions With Chaplains To Discuss Team Or Personal, Non-Work-Related Stressors, Gary Weisbrich, Sarah Sumner, Teresa Rangel

Providence Nursing Research Conference 2023 – Present

Background: Healthcare staff experience stress from the workplace when providing complex patient care and often may lean on specially trained spiritual support caregivers, or chaplains, for support navigating patient-related stressors. Yet, healthcare staff can also suffer from team-related or personal stressors that, if unresolved, could negatively impact care delivery. Little is known about whether, how often, and which staff may interact with chaplains for emotional support when experiencing non-patient-related stressors originating from work or personal lives.

Purpose: To describe the proportion of individuals who report discussing team-related or personal stressors with chaplains in the past 12 months, and to …

The Long-Term Economic Implications Of Burn Injury For Burn Survivors, Jacob M. Dougherty Bs, Hannan A. Maqsood Mbbs, Zhaohui Fan Md Mph, Stewart C. Wang Md Phd, Mark R. Hemmila Md, Naveen F. Sangji Md Mph

Medical Student Research Symposium

Introduction: The long-term economic implications of burn injury on patients and payors has not been well described. Burn injury can be costly due to prolonged intensive care, wound care, rehabilitation, psychological care, and reconstructive surgery that may be required well after the initial injury. We investigated index and post-acute payor and out-of-pocket (OOP) costs related to burn injury for in-patient care at 30 days, and up to 36 months post-discharge to understand the long-term economic implications for burn survivors.

Methods: An observational cohort study was conducted using a commercial claims database from IBM Watson Health® Marketscan. Patients age ≤ …
