Characterizing And Overcoming Resistance To Aminomethylspectinomycins In Gram-Negative Bacteria, Nisha Das

Theses and Dissertations (ETD)

Spectinomycin (SPC) is a broad-spectrum aminocyclitol antibiotic. Its use in agriculture has led to widespread resistance in enteric bacteria, necessitating the development of more effective analogs. Aminomethyl spectinomycins (amSPC) are modified spectinomycins with increased potency against many bacterial species. These species include Legionella pneumophila, which harbors a chromosomally encoded aminoglycoside modifying enzyme (AME). In this study, we follow up on this observation and examine the extent to which the amSPCs are substrates for AMEs through adenylation (ANTs) and phosphorylation (APH). APH(9)-Ia and ANT(3")(9) were expressed in E. coli BL21(DE3) and purified using the Ni-affinity chromatography. The ability of AMEs to …

Transversus Abdominis Plane Block: A Scoping Review, Liam Maher, Leanne Orians, Gabrielle Pappas, Lanny Coker Dnsc, Crna

Doctor of Nursing Practice Projects

The purpose of this project is to provide an overview of the literature on the analgesic effects of transverse abdominal plane (TAP) block and its effectiveness in reducing opioid consumption.

Intraoperative Dexmedetomidine For Reduction Of Postoperative Delirium In The Elderly: A Scoping Review, Gregory B. Harris Bsn, Rn, Srna, Brooke N. Hatchell Bsn, Rn, Srna, Davelin D. Woodard Bsn, Rn, Srna, Dwayne Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Background/Purpose: Post-operative delirium leads to significant morbidity in elderly patients, yet there is no regimen to prevent POD. Opioid use in the elderly surgical population is of the most significant risk factors for developing POD. The purpose of this scoping review is to recognize that Dexmedetomidine mitigates cognitive dysfunction secondary to acute pain and the use of narcotic analgesia by decreasing the amount of norepinephrine (an excitatory neurotransmitter) released during times of stress. This mechanism of action also provides analgesia through decreased perception and modulation of pain.

Methods: The authors developed eligibility criteria for inclusion of articles and performed a …

Pain Control: Opioid Vs. Nonopioid Analgesia During The Immediate Postoperative Period, Shamsie M. Lumpkin Bsn, Srna, Isaac W. Parrish Bsn, Srna, Austin S. Terrell Bsn, Srna, Dwayne S. Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Background Opioid analgesia has become the mainstay for acute pain management in the postoperative setting. However, the use of opioid medications comes with significant risks and side effects. Due to increasing numbers of prescriptions to those with chronic pain, opioid medications have become more expensive while becoming less effective due to the buildup of patient tolerance. The idea of opioid-free analgesic techniques has rarely been breached in many hospitals. Emerging research has shown that opioid-sparing approaches have resulted in lower reported pain scores across the board, as well as significant cost reductions to hospitals and insurance agencies. In addition to …

Dexmedetomidine Vs Fentanyl In Attenuating The Sympathetic Surge During Endotracheal Intubation: A Scoping Review, Alexandra Schwieger, Kaelee Shrewsbury, Paul Shaver, Dwayne Accardo Dnp, Crna

Doctor of Nursing Practice Projects

Purpose/Background Direct laryngoscopy and endotracheal intubation after induction of anesthesia can cause a reflex sympathetic surge of catecholamines caused by airway stimulation. This may cause hypertension, tachycardia, and arrhythmias. This reflex can be detrimental in patients with poor cardiac reserve and can be poorly tolerated and lead to adverse events such as myocardial ischemia. Fentanyl, a potent opioid, with a rapid onset and short duration of action is given during induction to block the sympathetic response. With a rise in the opioid crisis and finding ways to change the practice in medicine to use less opioids, dexmedetomidine, an alpha 2 …

Postoperative Nausea And Vomiting Implications In Neostigmine Versus Sugammadex, Corey Lee Johnson, Colton Bradley James, Sarah Grace Traughber, Charles Anthony Walker, Dwayne Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Purpose/Background: Postoperative nausea and vomiting (PONV) is a frequent complaint in the postoperative period, which can delay discharge, result in readmission, and increase cost for patients and facilities. Inducing paralysis is common in anesthesia, as is utilizing the drugs neostigmine and sugammadex as reversal agents for non-depolarizing neuromuscular blockers. Many studies are available that compare these two drugs to determine if neostigmine increases the risk of PONV over sugammadex. Sugammadex has a more favorable pharmacologic profile and may improve patient outcomes by reducing PONV.

Methods: This review included screening a total of 39 studies and peer-reviewed articles that looked at …

Opioid Free Anesthesia To Prevent Post Operative Nausea/Vomiting, Aleksander Acred, Milena Devineni, Lindsey Blake, Cindi Dabney Dnp, Crna

Doctor of Nursing Practice Projects

Purpose The purpose of this study is to compare the incidence of post-operative nausea and vomiting (PONV) in opioid-utilizing and opioid-free general anesthesia. Background PONV is an extremely common, potentially dangerous side effect of general anesthesia. PONV is caused by a collection of anesthetic and surgical interventions. Current practice to prevent PONV is to use 1-2 antiemetics during surgery, identify high risk patients and utilize tracheal intubation over laryngeal airways when indicated. Current research suggests minimizing the use of volatile anesthetics and opioids can reduce the incidence of PONV, but this does not reflect current practice.

Methods In this scoping …

Investigating The Role Of Znf384 Rearrangements In Acute Leukemia, Kirsten Dickerson

Theses and Dissertations (ETD)

Chromosomal rearrangements involving ZNF384 are the defining lesion in 5% of pediatric and adult B-cell acute lymphoblastic leukemia and tumors are characterized by aberrant myeloid marker expression. Additionally, ZNF384 rearrangements are the defining lesion in nearly half of pediatric B/myeloid mixed phenotype acute leukemia. These fusions juxtapose full-length ZNF384 to the N terminal portion of a diverse range of partners, most often, transcription factors or epigenetic modifiers. It has been shown that ZNF384-rearranged tumors have a distinct gene expression profile that is consistent between disease groups and N terminal partners. Genomic analyses of patient tumors has shown that ZNF384 fusions …
