The Relationship Of Cognitive Load And Different Participant Roles On Knowledge Retention In Simulation-Based Learning Among Undergraduate Nursing Students, Amanda Houston

Electronic Theses and Dissertations, 2020-2023

Background: High-fidelity simulation (HFS) is a cognitive load inducing educational tool that gives participants an opportunity to emulate clinical scenarios by assuming various roles. HFS offers opportunities for undergraduate nursing students to build fundamental knowledge that can replace, or enhance, clinical experiences. Cognitive load exists on a spectrum and negatively impacts learning when learners are at either extreme of the spectrum. Cognitive load is comprised of the three subcomponents of intrinsic, extraneous, and germane load. Not much is known about different subcomponents or their ability to prediction immediate knowledge and knowledge retention in students who play fundamentally different roles, as …

Undergraduate Nursing Students' Depth Of Reflection And Perceptions Of Self-Debriefing Following Virtual Simulation: A Multi-Method Descriptive Study, Valorie Mackenna

Electronic Theses and Dissertations, 2020-2023

Virtual simulation is a method of simulation-based education in which students participate in a clinical experience within a computer program and away from a clinical environment or classroom. This innovation makes simulation more accessible for learning, but also more challenging when it comes to providing a debriefing activity directly afterward by a facilitator. The purpose of debriefing is to afford learners the opportunity to reflect on the experience with a goal toward improvement. From the best practice standards, two recommendations stipulate that a debriefing session should occur soon after a simulation and should promote reflection. Self-debriefing is uniquely capable of …

Paroxetine Is Pro-Inflammatory In Human Brain Microvascular Endothelial Cells, Syeda Hashimi, Sulay Patel, Omar Hassan, Bukola Odeniyi

Graduate Research Posters

BACKGROUND: Paroxetine is an antidepressant that is widely used. However, Paroxetine possesses anticholinergic properties which may contribute to cognitive decline in older adults. Surprisingly, the mechanisms of the cognitive decline of anticholinergic drugs in older adults remains elusive. A hypothesis is that a loss of cholinergic signaling is pro-inflammatory in the brain. We designed experiments to determine if Paroxetine is pro-inflammatory in Normal Human Brain Microvascular Endothelial Cells (NHBMECs).

METHOD: NHBMECs were grown at 5% CO2, 37C and 95% relative humidity until 90% confluent. NHBMECs were treated with the RNA free water as control, Paroxetine as 1.67x 10 4 mM/mol, …

Graduate Research Posters

Background: Doxorubicin (DOX) is a potent chemotherapeutic widely used for solid tumors (1). Despite high efficacy in 2D cell culture, DOX efficacy does not translate to in vivo lung cancer models (2). Major side effects such as cardiotoxicity may be alleviated with nano-based drug delivery systems (nanoDDS). However, tumor penetration of DOX and DOX-nanoDDS is largely unknown and is an additional barrier to effective clinical therapy (3). Here we describe a nanoDDS capable of enhancing the penetration of DOX.

Methods: DOX was conjugated to generation 4 poly(amido-amine) dendrimers through (GFLG) tumor- liable bond. G4SA-GFLG-DOX was synthesized/characterized. spheroids were formed of …

Graduate Research Posters

Background. Kineret (Anakinra) is an interleukin-1 antagonist that is under investigation for its novel clinical application treating patients that have heart failure with reduced (<50%) ejection fraction (HFrEF). A prior study from our group indicated that Anakinra may restore heart function by addressing dysregulations in HFrEF metabolic pathways. Herein, we attempt to elicit Anakinra’s effects on both metabolome and lipidome.

Methods. Lipids and metabolites that had previously been quantified by mass spectrometry (MS) from patients (n=49) who had ≥2 mg/L of high-sensitivity C-reactive protein (hs-CRP) were mTIC normalized and transformed. We conducted a stepwise Linear Discriminant Analysis (r- LDA) to test Anakinra (2 and 12 weeks) vs placebo for separation from combined baseline. Metabolic pathway analysis was performed with Fisher’s exact test algorithm for detection of over-represented and enriched analytes. Univariate analysis (one tailed t-test …

Guadecitabine, In Combination With Cyclophosphamide, Promotes Anti- Cancer Immunity In Balb/C Mice Bearing 4t1 Mouse Mammary Carcinoma, Carmen Camarena, Timothy M. Smith, Rebecca K. Martin Phd, Harry D. Bear Md

Graduate Research Posters

Background: The extremely high mortality rate of patients diagnosed with triple negative breast cancer makes it one of the deadliest forms of cancer. Due to the heterogenous nature of tumors, complete clearance is not achieved and clonal selection occurs resulting in tumor cells evading the immune system. I aim to design a therapeutic intervention that is able to elicit an effective immune response against the tumor and instill immunological memory to eradicate primary and metastatic lesions. I hypothesize that the combination of Guad and Cyp will synergize and promote anticancer immunity via increased expression of neo-tumor antigens and depletion of …
