Variability And Outcomes Of Medical And Lifestyle Management Of Peripheral Arterial Disease At The Time Of Lower Extremity Bypass, Ryan Howard, Jeremy Albright, Matthew Corriere, Nicholas Osborne, Eugene Laveroni, Peter Henke

Conference Presentation Abstracts

Background: First-line treatment of peripheral arterial disease (PAD) involves medical therapy and lifestyle modification. Specifically, the 2016 American Heart Association/American College of Cardiology guidelines for the management of PAD make Class I recommendations for antiplatelet therapy, statin therapy, antihypertensive therapy, and cilostazol therapy, as well as exercise therapy and smoking cessation. Although evidence supports medical and lifestyle management of PAD before surgical intervention, it is currently unclear whether clinical practice reflects this. Moreover, it is also unknown whether variability in medical and lifestyle optimization before revascularization affects short- and long-term outcomes. This study was conducted to determine the proportion of …

Introduction: Dural tails are thickened contrast-enhancing portions of dura associated with some meningiomas. Prior studies have demonstrated the presence of tumor cells within the dural tail, however their inclusion in radiation treatment fields remains controversial. We evaluated the role of including the dural tail when treating a meningioma with stereotactic radiation and the impact on tumor recurrence.

Methods: This is a retrospective, single-institution, cohort study of patients with intracranial World Health Organization (WHO) grade 1 meningioma and identified dural tail who were treated with stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) from January 2012 to December 2018. SRS and …

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 …

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 …

Eagle Syndrome: Efficacies Of Medical And Surgical Treatments, Kirklin Mitchell

Capstone Showcase

Eagle Syndrome is a rare syndrome caused by elongation of the styloid process of the temporal bone or calcification of the stylohyoid ligament occurring in a very small percentage of the population that can cause a wide range of common symptoms, leading to it being often misdiagnosed. While there are no set standards for treating Eagle Syndrome, both pharmaceutical and surgical options exist. Pharmaceutical options are often ineffective in long term treatment so surgery is usually required for full symptom resolution. Transoral and Transcervical surgeries have similar efficacies but each come with important drawbacks when considering which type of surgery …

Percutaneous Coronary Intervention Using Second Generation Drug-Eluting Stents Vs Coronary Artery Bypass Graft In Left Main Coronary Artery And Multivessel Coronary Artery Disease, Eric Kim

Capstone Showcase

Many of the studies that are used in reference to the clinical decision making between PCI vs CABG use BMS or first-generation DES as a comparison. With the advancement of stent technology, second-generation DES have emerged with improved efficacy and overall outcome rates compared to BMS and first-generation DES. Some of the newer studies such as EXCEL1-2 , demonstrated noninferiority of second-generation DES to CABG but there are limited studies that support this conclusion. Currently, the studies remain divided in the impact of newer-generation PCIs, and 10-year follow up studies may be required to further validate noninferiority before it can …

Kidney Disease After Heart And Lung Transplantation, Carlos M Zapata, Hassan N Ibrahim

Faculty, Staff and Student Publications

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as …

Small Bowel Stomas Are Associated With Higher Risk Of Circulating Food-Specific-Igg Than Patients With Organic Gastrointestinal Conditions And Colostomies, Walker K. Carson, Joseph L. Baumert, Jennifer Clarke, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Objective The effects of food sensitivity can easily be masked by other digestive symptoms in ostomates and are unknown. We investigated food-specific-IgG presence in ostomates relative to participants affected by other digestive diseases.

Design Food-specific-IgG was evaluated for 198 participants with a panel of 109 foods. Immunocompetency status was also tested. Jejunostomates, ileostomates, and colostomates were compared with individuals with digestive tract diseases with inflammatory components (periodontitis, eosinophilic esophagitis, duodenitis, ulcerative colitis, Crohn’s disease, and appendicitis), as well as food malabsorption due to intolerance. A logistic regression model with covariates was used to estimate the effect of the experimental data …

Massive Blood Transfusion Practises: A Survey Of Level 1 Trauma Centers, Rebecca C. Parker

DNP Research Projects

Abstract

Background: Traumatic injury is the leading cause of death for individuals under the age of 45 years old, regardless of race, origin, or sex (CDC, 2019). Among patients who sustain traumatic injury, hemorrhage remains the leading cause of death (American College of Surgeons [ACS], 2014). Hemodynamic stability may be achieved through administration of blood products such as packed red blood cells (PRBC), plasma, and platelets (PTL). Patients with severe exsanguination may require administration of blood products in large quantities, also known as a massive blood transfusion (MBT).

Local Problem: Nationally, traumatic injury accounts for over 150,000 deaths annually (American …

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 …
