Department of Surgery Faculty Papers

Objectives

Endovascular procedures for lower extremity revascularization are becoming more commonplace due to low morbidity, mortality, and shorter length of stay. The role of open bypass must be reconsidered. Aortobifemoral bypass is the gold standard for extensive aortoiliac occlusive disease (AIOD); however, thoracodistal bypass holds a niche position. We investigate indications and outcomes of thoracodistal bypass.

Methods

Medical records of five patients who underwent thoracodistal bypass at Thomas Jefferson University Hospital (TJUH) between 2012 and 2019 were reviewed. Contemporary and historical literature was reviewed.

Results

Indications included calcified paravisceral pathology, previous failed or infected bypass grafts, and prior abdominal operations. …

Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, and antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy to manage pandemic. Although none of the currently approved vaccines are live-attenuated, several reports of disease flares, waning protection, and acute-onset syndromes have emerged as short-term adverse events after vaccination. Hence, scientific literature falls short when discussing potential long-term effects in vulnerable cohorts. The COVAD-2 survey follows on from the baseline COVAD-1 survey with the aim to collect patient-reported data on the long-term …

Total Joint Implant Alloy Oxide Layer Cell-Induced Damage, Chandler K. Sears Aug 2022

Total Joint Implant Alloy Oxide Layer Cell-Induced Damage, Chandler K. Sears

Longitudinal Scholar's Project

Cobalt-Chromium alloy is commonly used in total joint arthroplasty (TJA). Several studies have investigated evidence of inflammatory-cell-induced-corrosion (ICIC) causing pitting in TJA retrieved implants. Others have determined that placing orthopedic alloys into lower pH solutions will increase the rate of corrosion. We have determined that electrochemical potential and corrosion rates of human knee synovial fluid show a variation greater than an order of magnitude. This means there is going to be a significant variation between a patient’s local environment of the TJA implant and may affect how macrophages interact with alloy oxide layers. Knee disability can be quantified by using …

Department of Medicine Faculty Papers

Clinically-available blood pumps and total artificial hearts for pediatric patients continue to lag well behind those developed for adults. We are developing a hybrid, continuous-flow, magnetically levitated, pediatric total artificial heart (TAH). The hybrid TAH design integrates both an axial and centrifugal blood pump within a single, compact housing. The centrifugal pump rotates around the separate axial pump domain, and both impellers rotate around a common central axis. Here, we concentrate our development effort on the centrifugal blood pump by performing computational fluid dynamics (CFD) analysis of the blood flow through the pump. We also conducted transient CFD analyses (quasi-steady …

The Impact Of Delayed Surgical Care On Patient Outcomes With Alimentary Tract Perforation: Insight From A Low-Middle Income Country, Hasnain Zafar, Taha Ahmad Zaka-Ur-Rehman, Muhammad Sohaib Khan, Shayan Ahmed, Amir Hafeez Shariff

Section of General Surgery

Introduction: In-patient delay is associated with increased mortality in patients with alimentary tract perforations. Access to surgical care is a glaring health issue in low-middle income countries (LMICs), where patient presentation is also delayed for a myriad of reasons, which can be broadly categorized as social/cultural, financial, and structural in their nature. The impact these delays have on surgical outcomes in low-middle income countries is not known.
Methods: A retrospective cohort study of patients who underwent emergency laparotomy for alimentary tract perforation from July 2015 to June 2018 was conducted at a tertiary care hospital in Karachi, Pakistan. Time was …

Background Social and environmental factors play an important role in the rising health care burden of cardiovascular disease. The Centers for Disease Control and Prevention developed the Social Vulnerability Index (SVI) from US census data as a tool for public health officials to identify communities in need of support in the setting of a hazardous event. SVI (ranging from a least vulnerable score of 0 to a most vulnerable score of 1) ranks communities on 15 social factors including unemployment, minoritized groups status, and disability, and groups them under 4 broad themes: socioeconomic status, housing and transportation, minoritized groups, and …

Purpose: Literature on outcomes after SSRF, stratified for rib fracture pattern is scarce in patients with moderate to severe traumatic brain injury (TBI; Glasgow Coma Scale ≤ 12). We hypothesized that SSRF is associated with improved outcomes as compared to nonoperative management without hampering neurological recovery in these patients.

Methods: A post hoc subgroup analysis of the multicenter, retrospective CWIS-TBI study was performed in patients with TBI and stratified by having sustained a non-flail fracture pattern or flail chest between January 1, 2012 and July 31, 2019. The primary outcome was mechanical ventilation-free days and secondary outcomes …
