A Serological Analysis Of Sars-Cov-2 Infection In The Obstetric Population, Sophia Rose

CMC Senior Theses

In December 2019, the surfacing and spread of a novel coronavirus, SARS-CoV-2, resulted in the global COVID-19 pandemic. As a viral antigen, SARS-CoV-2 poses a particular threat to the obstetric population due to physiological and immunological changes that women face during pregnancy. While recent studies have found that SARS-CoV-2 may have better clinical outcomes as compared to other betacoronaviruses, adverse pregnancy events such as ICU admission, preeclampsia, and/or preterm birth have been associated with COVID-19. Progress has been made in better understanding the pathophysiology of SARS-CoV-2 in pregnancy, but there is still much to be known about the interaction …

A Proposed Method To Verify Physician Visual Estimation Of Intraoperative Corneal Edema From Refractive Measurement Images During Cataract Surgery, Karalee Corley

CMC Senior Theses

A patient’s resultant vision quality in a restorative Femtosecond Laser Assisted Cataract Surgery (FLACS) can be fine tuned via an intraoperative measurement of refractive power and axis of astigmatism in the aphakic state. Standard preoperative measurements often disagree with intraoperative measurements (Optiwave Refractive Analysis; Alcon, Inc.) on account of the inclusion or exclusion of posterior corneal curvature, leaving the ultimate lens selection to physician discretion. One additional suggested cause of disagreement is swelling at the corneal incision site (Corley and Carmack 2020).The following proposes a method to verify visual estimation of intraoperative corneal swelling from 2D gray-scale images collected during …

Differential Impact Of Static Lung Compliance On Need For Reintubation In Mechanically Ventilated Covid-19 Positive And Negative Patients, L A. Abplanalp, F Ionescu, O Gomez Rojas, E Castillo, G B. Nair

Conference Presentation Abstracts

Rationale: The decision to liberate from mechanical ventilation (MV) remains the result of multi-disciplinary discussion based on imperfect clinical tools such as the rapid shallow breathing index and spontaneous breathing trials. We have previously shown that static lung compliance (Cp) can help identify patients at high risk of reintubation despite meeting traditional criteria. In this study, we hypothesized that low Cp may not explain the reintubation risk in the distinct pathophysiologic scenario of COVID-19. Methods: This was a retrospective, multi-center analysis of COVID-19-negative (Dec. 2017-Dec. 2019) and -positive patients (Mar.-Oct. 2020) who required MV and were liberated during the same …

Pulmonary Cement Emboli: An Underreported Phenomenon Or Rare Kyphoplasty Complication, A Cimino, A Alchakaki

Conference Presentation Abstracts

Kyphoplasty is an intervention to treat and stabilize painful vertebral compression fractures by injecting Polymethymethacrylate (PMMA) cement in the vertebral cavity. It has become increasingly important procedure in pathologic compression fracture treatment. Pulmonary cement embolism (PCE) happens by leakage of cement through the venous plexus or retrograde migration in the arterial vessels to aorta. It was reported as a rare complication of this procedure (3.5%) but others have suggested that because of paucity in symptoms, PCE is often overlooked and can happen in up to 28.6% of kyphoplasty patients. PCE cause a wide spectrum of symptoms ranging from asymptomatic to …

Evaluating Non-Pharmaceutical Sleep Hygiene Interventions For The Prevention Of Delirium And Improvement In Sleep Quality In Critical Care, Sonja L. Colby

Honors Undergraduate Theses

Patients admitted to an adult intensive care unit (ICU) are at risk of developing an acute condition known as ICU delirium, which can impact patients’ length of hospital stay and increase short term and 6-month mortality. The cause of ICU delirium is multifactorial, and lack of quality sleep is a known risk factor. Patients’ sleep in the ICU is frequently interrupted by clinicians involved in their care and equipment alarms. Sleep hygiene interventions to minimize these interruptions for the patient are one strategy to reduce the risk of ICU delirium. Examples of sleep hygiene interventions include eye masks, earplugs, and …

Obstetrical Nursing Care And Cesarean Section Delivery Rates In Laboring Women: An Integrative Review Of Literature, Ayana Cornelius

Sixty-four percent would like to receive results that cannot guide treatment, and lower tolerance of uncertainty, self-efficacy, and perceived importance were associated with this preference. Fifty-nine …

The Relationship Between First Case On-Time Starts, Turnover Times, And Operating Room Productivity, Rhafia Bucoy

Walden Dissertations and Doctoral Studies

Operating room (OR) managers struggle to manage day-to-day surgical operations while meeting and exceeding organizational productivity amid the COVID-19 pandemic. The deferral of surgeries contributes to millions of backlogs of surgical case volume and unintended negative consequences. Grounded in the proposition that first-case on-time starts (FCOTS) and turnover time (TOT) are correlates of OR productivity, the purpose of this quantitative correlational study was to examine the relationship between FCOTS, TOT, and OR productivity. Archival data from 136 electronic surgical records were collected from two free-standing ambulatory surgery centers and analyzed using multiple regression. The results of the one-service, eye-specialized, ambulatory …

Effectiveness Of Stabilized Hypochlorous Acid In Acute Peritonitis Treatment: A Murine Surgical Study, Benjamin Michael Pomeroy

Graduate Theses/Dissertations

Peritonitis is an inflammatory condition affecting the mesothelial cells that line the peritoneal cavity and is commonly induced by bowel perforations. This medical emergency is treated through antibiotic therapy and surgical intervention followed by tissue irrigation (lavage). Acute treatments aim to remove the bacterial burden, however recurring peritoneal infections occur at high rates and contribute to patient morbidity. These recurring infections are likely due to the inability of lavage solutions to remove the entire massive intra-abdominal bacterial load due to intestinal perforation. Numerous antiseptic solutions and antibiotic additives have been evaluated in their ability to improve source control by abdominal …

Monitoring The Systemic Immune System To Understand And Improve The Efficacy Of Immunotherapy For Metastatic Osteosarcoma, Justin Edward Markel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Osteosarcoma (OS) is a complex tumor with no effective targeted therapies due to its genomic heterogeneity and pleomorphism. The immune response it creates, particularly against metastatic lesions, is considerable; however, various suppressive mechanisms induced by the tumor prohibit its effectiveness. The presence of infiltrating lymphocytes suggests that therapeutic disinhibition through checkpoint blockade could increase antitumor immunity, though none have been successful in clinical trials. The complexities of the immune response to OS tumors have yet to be unraveled; however, there is evidence to suggest that cell-mediated immunity (CMI, specifically T cells, Natural Killer [NK] cells, and myeloid-lineage cells [MLCs]) plays …

Education And Awareness Of Workplace Hazards: An Educational Intervention For First Responder Trainees, Emily Portune

All Master's Theses

First responder paramedics, emergency medical technicians (EMTs), and firefighters provide emergency services to communities everywhere, often in life-threatening circumstances. At the same time, these first responders face high-stress life and death situations and may also endure unique workplace hazards like racism, sexual harassment and discrimination, verbal and physical patient assault, and extreme sleep deprivation. These hazards make prehospital providers vulnerable to mental illness, a fact proven by preexisting research that found more than 85% of first responders reported negative mental health symptoms and outcomes directly related to their career. Not only are prehospital providers at high risk of mental illness; …
