Alt Free Flap Coverage After Carotid Endarterectomy In The Setting Of Severe Radiation Changes, Richard F. Guidry, Hannah E. Doran, Mark W. Stalder

School of Medicine Faculty Publications

Carotid endarterectomy with patch angioplasty is commonly performed for severe atherosclerotic disease to reduce stroke risk. After neck radiation, loss of tissue planes; reactive fibrosis of skin; contraction; and rarely, necrosis of skin may occur, leading to severe wound complications and possible exposure of carotid artery reconstruction. Historically, local myocutaneous flaps have been performed to provide soft tissue coverage; however, these procedures may be associated with increased donor site morbidity and can be affected by radiation changes. This report describes the novel use of a fasciocutaneous free flap for durable vascularized soft tissue, and the associated secondary benefit of improved …

STUDY DESIGN: Retrospective cohort study.

PURPOSE: This study aimed to determine whether the initiation of anti-calcitonin gene-related peptide (CGRP inhibitor) medication therapy for migraines was also associated with improvements in back/neck pain, mobility, and function in a patient population with comorbid degenerative spinal disease and migraine.

OVERVIEW OF LITERATURE: CGRP upregulates pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-6, brain-derived neurotrophic factor, and nerve growth factor in spinal spondylotic disease, which results in disc degeneration and sensitization of nociceptive neurons. Although CGRP inhibitors can quell neurogenic inflammation in migraines, their off-site efficacy as a therapeutic target for discogenic back/neck pain …

Exploring The Uncommon: A Case Report On Localized Peritonitis Caused By Ingested Toothpick, Narmeen Asif, Salva Shariq, Abdul Rehman Alvi

Background: Brain arterial diameters (BADs) are novel imaging biomarkers of cerebrovascular disease, cognitive decline, and dementia. Traditional vascular risk factors have been associated with BADs, but whether there may be genetic determinants of BADs is unknown.

Methods and results: The authors studied 4150 participants from 6 geographically diverse population-based cohorts (40% European, 14% African, 22% Hispanic, 24% Asian ancestries). Brain arterial diameters for 13 segments were measured and averaged to obtain a global measure of BADs as well as the posterior and anterior circulations. A genome-wide association study revealed 14 variants at one locus associated with global BAD at genome-wide …

Improving Outcomes For Women Following Gynecological Surgery Through Implementation Of Multimodal Analgesia As Part Of An Enhanced Recovery After Surgery (Eras) Protocol, Shannan M. Case

Doctor of Nursing Practice Projects

The opioid epidemic in the United States has been a continuous public health crisis, as opioid-associated overdose has become one of the leading causes of death. The risk of opioid misuse increases following exposure to opioids perioperatively. As a result, anesthesia providers are facing a significant shift in practice to decrease opioid administration while adequately managing perioperative pain. While opioids have historically been the mainstream for perioperative pain management, multimodal analgesic (MMA) regimens as part of Enhanced Recovery After Surgery (ERAS) programs are being utilized as alternative methods. With these programs, opioids are reduced by administering non-opioids with neuraxial and …

Massive Transfusion And Shock Index, Kasey House

MSN Capstone Projects

Hemorrhagic shock is one of the leading causes of preventable death in military trauma patients. Literature shows that pre-hospital transfusions of blood products within the combat environment have shown to have a greater likelihood of survival. This has produced a challenge in the pre-hospital setting to have a standardized method of predicting the patient’s need for a massive transfusion. In the last few years, the development of a Massive Transfusion Protocol (MTP) has become the standard to quickly deliver blood products to actively bleeding patients. Every minute waiting to administer blood products increases mortality by 5%.

While initiating an MTP …

Mathematics Faculty Publications

INTRODUCTION: The relationship between socioeconomic status and neurosurgical outcomes has been investigated with respect to insurance status or median household income, but few studies have considered more comprehensive measures of socioeconomic status. This study examines the relationship between Area Deprivation Index (ADI), a comprehensive measure of neighborhood socioeconomic disadvantage, and short-term postoperative outcomes after lumbar fusion surgery. METHODS: 1861 adult patients undergoing single-level, posterior-only lumbar fusion at a single, multihospital academic medical center were retrospectively enrolled. An ADI matching protocol was used to identify each patient's 9-digit zip code and the zip code-associated ADI data. Primary outcomes included 30- and …

From The Borders Edge To The Brink Of Death: A Case Of A Traumatic Pancreatic Injury And Whipple Procedure In The Rio Grande Valley, Valentine S. Alia, Ed W. Alvarado, Edward M. Diaz, Daniel Albo, Roger Galindo

School of Medicine Publications

The traumatic pancreatoduodenectomy, also known as the traumatic Whipple, is a specialized surgical procedure often reserved for extreme cases in which an individual suffers traumatic injuries to the pancreas, duodenum, or periampullary structures. Traditionally, a Whipple procedure is a complex surgery involving the removal of the head of the pancreas, duodenum, and a portion of both the bile duct and stomach, for the management of pancreatic head cancer. In underserved communities where limited access to healthcare is coupled with a higher incidence of trauma, the lack of specialized and supportive care for patients suffering from pancreatic injuries may lead to …

The most prevalent conditions among ocular surgery and COVID−19 patients are fungal eye infections, which may cause inflammation and dry eye, and may cause ocular morbidity. Amphotericin-B eye drops are commonly used in the treatment of ocular fungal infections. Lactoferrin is an iron-binding glycoprotein with broad-spectrum antimicrobial activity and is used for the treatment of dry eye, conjunctivitis, and ocular inflammation. However, poor aqueous stability and excessive nasolacrimal duct draining impede these agens' efficiency. The aim of this study was to examine the effect of Amphotericin-B, as an antifungal against Candida albicans, Fusarium, and Aspergillus flavus, and Lactoferrin, …

Faculty, Staff and Students Publications

OBJECTIVE: Acute kidney injury after cardiac surgery increases morbidity and mortality. Diagnosis relies on oliguria or increased serum creatinine, which develop 48 to 72 hours after injury. We hypothesized machine learning incorporating preoperative, operative, and intensive care unit data could dynamically predict acute kidney injury before conventional identification.

METHODS: Cardiac surgery patients at a tertiary hospital (2008-2019) were identified using electronic medical records in the Medical Information Mart for Intensive Care IV database. Preoperative and intraoperative parameters included demographics, Charlson Comorbidity subcategories, and operative details. Intensive care unit data included hemodynamics, medications, fluid intake/output, and laboratory results. Kidney Disease: Improving …

Surgical Techniques/Case Videos-Complex Aortic Case: Top Tips (Taaar), Joseph Stapleton Coselli

Faculty, Staff and Students Publications

This complex case study describes the surgical approach for a patient with chronic aortic dissection and multiple comorbidities. The patient had multiple previous surgeries, including aortic repair. The surgical approach involved a thoracoabdominal aortic aneurysm repair with left heart bypass, spinal fluid drainage, selective visceral perfusion, and protection of the surviving kidney. A Dacron tube graft was used to replace the damaged area.

Thoracoabdominal Aortic Aneurysm: A Journey Through The Distal Aorta, Joseph Stapleton Coselli

Faculty, Staff and Students Publications

The field of surgical aortic repair has advanced significantly over time, transitioning from aneurysm ligation to homografts, then to Dacron grafts, and now endovascular procedures. With new endovascular technologies emerging, they are likely to dominate the field of aortic surgery, but surgeons must exercise caution and not abandon their open-surgery skills. Open repair of thoracoabdominal aortic aneurysm surgery continues to be a durable operation. As the field continues to evolve, further research is needed to advance this complex surgical endeavor.

The topic of women and cancer spans broad terrain, beyond women’s cancers and the biomedical aspects of any type of cancer that women in all their diversities might experience. It is inclusive of the ways in which sex and gender influence exposures to cancer risk factors, interactions with the cancer health …

Advanced Breast Cancer Care: The Current Situation And Global Disparities, Aruni Ghose, Susannah Stanway, Bhawna Sirohi, Miriam Mutebi, Sarah Adomah

General Surgery, East Africa

Objectives: Advanced breast cancer (ABC) is an incurable disease. The number of people living with ABC has increased globally. Disparities in ABC care exist at both individual and system levels. ABC cases in most low- and middle-income countries (LMICs) are underreported due to a lack of national cancer registries. Harmonized guidelines for resource stratification and capacity building in LMICs are under way.

Data sources: MEDLINE, Cochrane, and Google Scholar databases were used.

Conclusion: To improve ABC outcomes and resolve disparities, more robust health systems or pathways need to be developed across the cancer continuum in addition to social education.
