Microparticle-Based Scaffold for Recovery from COVID-19-Associated Intubation Scarring

  • Donald Griffin, School of Engineering, Biomedical Engineering
  • James Daniero, School of Medicine, Otolaryngology-Head and Neck Surgery
  • Patrick Cottler, School of Medicine, Plastic Surgery

An unfortunate side effect of ICU treatment of COVID-19 patients has been a dramatic increase in long-term intubation. Extended intubation of greater than 10 days results in a high likelihood of pressure-associated ulcers and production of a poorly healing aerodigestive mucosal (ADM) defect, requiring surgery with risks of reoccurrence and potentially fatal complications. The goal of this project is to design and validate a biomaterial device that will simultaneously accelerate ADM healing and prevent scar recurrence following surgical excision of fibrotic blockages.

Analysis of Respiratory Kinematics (ARK): novel wearable technology for remote detection of labored breathing in COVID-19 patients

  • Shrirang M. Gadrey, School of Medicine, Geriatrics and Palliative Care
  • Ronald D. Williams, School of Engineering, Electrical and Computer Engineering
  • J. Randall Moorman, School of Medicine, Physiology and Biomedical Engineering
  • Sarah J. Ratcliffe, School of Medicine, Public Health Sciences, Biostatistics

Labored breathing is a strong predictor of respiratory failure. A method to monitor labored breathing without a bedside evaluation is urgently needed, especially for COVID-19 patients.

The ARK (Analysis of Respiratory Kinematics) system uses unobtrusive wearable sensors to detect and quantify labored breathing. The team plans to test this technology with ER patients with COVID-19 and determine the respiratory kinematic signatures of COVID-19.

This is a high risk, high impact approach to develop a new therapeutic to eliminate virally infected cells and viral load to decrease the severity of infection and mortality associated with SARS-CoV-2 infection.

Technology Driven Entrepreneurial Solutions to Address Healthcare Worker Protection Needs

  • Dr. Michael D. Williams, School of Medicine, General Surgery
  • Gaurav Giri, School of Engineering, Chemical Engineering
  • Dr. Bala Mulloth, Frank Batten School of Leadership and Public Policy

To address the looming personal protective equipment (PPE) shortage, this project will perfect a ‘metal organic framework’ (MOF) as a new synthesizable coating for fabrics, to rapidly create personal protective equipment (PPE) for healthcare workers and individuals with the potential for a >10-fold increases in the filtration capacity of cotton, with minimal impact on breathability. It is anticipated that these MOF-treated materials will have a substantial lifetime, will be washable and reusable, and manufactured at a cost significantly below the current competitive and gold-standard N95 masks.

Mucosal Subunit Vaccine for SARS-CoV2

  • William Petri, School of Medicine, Infectious Diseases and International Health
  • Peter Kasson, School of Medicine, Molecular Physiology and Biological Physics, School of Engineering, Biomedical Engineering

The aim of this project is to develop a mucosal S glycoprotein vaccine that is envisioned to be deliver intra-nasally. Vaccine efficacy will be measured by micro-neutralization using mucosal IgA and plasma IgG including the ability of immune sera to block receptor binding, viral membrane fusion, and cross-protect against SARS-CoV-1. Protection in mice expressing the human ACE2 receptor will also be tested.

IL-13 as a Predictor and Contributor to Hypoxic Respiratory Failure in COVID-19

  • William Petri, School of Medicine, Infectious Diseases and International Health
  • Barbara J. Mann, School of Medicine, Infectious Diseases
  • Jason Papin, School of Engineering, Biomedical Engineering, School of Medicine, Infectious Diseases and International Health, Biochemistry and Molecular Genetics

The team has discovered that the IL-13, a cytokine, helps predict whether a COVID-19 patient will need intubation and ventilation. They plan to study the plasma samples collected daily from UVA COVID-19 patients, develop a mouse model of SARS-CoV-2 pneumonia, and target the IL-13 pathway to describe immune and metabolomic features underpinning the ability of IL-13 levels to predict the future need for mechanical ventilation.

Association of Anti-phospholipid antibodies with thromboembolism in COVID-19

  • Dana P. Albon, School of Medicine, Pulmonary and Critical Care
  • Lindsay Somerville, School of Medicine, Associate Director Adult Cystic Fibrosis Medicine
  • Heather M. Bruschwein, School of Medicine, Psychiatry & Neurobehavioral Sciences

This team will study whether COVID-19 infection causes an elevation of antiphospholipid antibodies and consequently causes thrombosis. They will study COVID-19 patient samples for elevated antibody levels to generate their preliminary data, which could lead to changes in patient care and an identification of which patients could benefit from anticoagulation therapies.

Clinical Trial of Multi-Peptide Vaccine for SARS-CoV-2 and Future SARS Variants
