COVID-19 had infected more than 2 million people worldwide by April 2020, including more than 9,000 health care workers who had inadequate access to standard personal protective equipment. As a result, health care workers developed their own equipment and guidelines to protect themselves from infection though all of these devices lacked proof of effectiveness. The goal of this project was to test the effectiveness of the Badger Box, a novel portable negative pressure isolation box that can act as both a physical barrier and containment unit for aerosolized viruses. Preliminary results indicated the Badger Box’s capability to capture over 95 percent of particles.

The COVID-19 Response grants awarded by the Faculty Grant support UW–Madison researchers across campus in scientific, medical and public health approaches to lessening the impact of COVID-19 through improved testing, treatments and vaccine development, as well as projects that aim to protect the public and healthcare workforce from the virus.

Heart failure continues to be a major health issue in the United States, characterized by 6 million adults affected in the years 2015-2018, according to the American Heart Association. Ischemic injury is caused by the absence of or diminished flow of blood, which can lead to heart disease and heart failure that affects the function of the heart by reducing its ability to pump blood effectively. This project explored new strategies to repair the adult human heart following injury caused by heart disease, which can cause irreversible loss of part of the heart muscle. The research team identified mechanisms that occur in heart regeneration in newborns that could be applied to adult hearts in order to aid in cardiac regeneration. These data support the possibility of people regaining cardiac function after injury.

Patients with unmet social needs —such as housing and food insecurity —need to be paired with available community resources. At two UW Health clinics since 2016, student navigators havehelped connect patients with resources. This study will determine whether student navigators’ training and experience enhances their inter-professional development.

Studies have implicated the failure of proper chromosome segregation, a process that is critical for cell proliferation and for maintaining life in all organisms, in both cancer and birth defects. This project explored the scientific premise that the kinetochore, a protein structure that forms during cell division, ensures proper chromosome segregation and prevents errors in mitosis. This project provided fundamental insights into cancer and developmental diseases by yielding new understanding of kinetochore functions. Through the work completed during this grant period, the researchers were able to make progress on developing a novel super-resolution imaging methodology which is not only well-suited to studying kinetochore dysfunction, but also can be utilized for broad research fields.

Lupus — an autoimmune disease that causes inflammation and organ damage — disproportionately affects patients of color and those of low socioeconomic status, who also experience higher rates of associated kidney disease and early death. Ensuring that patients get regular care could help keep symptoms in check, but retention predictors in lupus care are poorly understood. This study defined retention in care for different demographic groups in Wisconsin, finding that those from the most disadvantaged neighborhoods were the most at-risk of ~60% lower retention in care. The insights generated from this research have the potential to help providers reduce lupus outcome disparities in the future.

In Wisconsin, 750,000 people live with diabetes, and 25 percent of those individuals will develop a diabetic foot ulcer (DFU), a common complication of diabetes, in their lifetime. DFUs can remain open for a long time, and it can be difficult to predict which of these wounds will respond to treatment and heal or require amputation. Wound tissue supports the colonization of a diverse community of microbes referred to as a microbiome. The microbiome in the wound tissue is thought to sustain inflammation which impairs healing and tissue repair. There is a critical, unmet need to develop methods that predict if diabetic wounds will heal in response to treatment, or if they will remain open and healing will be stalled due to a complex microbiome. In this study, researchers hypothesized that the wound microbiome interacts with host healing pathways and genes that control tissue repair. Ultimately, they found that anaerobic bacteria species, which can survive and grow with no oxygen, are more abundant and transcriptionally active in the microbiome of persistent and amputated wounds. Therefore, anaerobic bacteria may serve as a predictive biomarker of wound healing. The research team has received a $26,000 Wisconsin Alumni Research Foundation (WARF) Technology Accelerator Grant and a $2 million NIH grant to expand their work.

Antibiotic resistance makes drugs less effective at treating infections, which can be very dangerous. This study explored the role that dietary fiber intake and the diversity of microorganisms in the gut may play in reducing the risk of colonization by multidrug resistant organisms (MDROs). The study found higher rates of MDRO colonization in older, low-income, and urban-living individuals and that increased dietary fiber intake may be associated with slightly lower rates of MDRO gut colonization. Further study using leveraged grant funding in underway.

In Wisconsin, people of Hmong ancestry are infected by a particular fungal lung disease at rates up to 100 times higher than people of European ancestry, a concerning public health disparity. The researchers identified the genetic basis for susceptibility to the fungal infection in people of Hmong ancestry, providing new opportunities for treatment and education.

The COVID-19 pandemic highlighted the need for detailed and timely information in making public health and operational decisions. This project aimed to develop an advanced COVID-19 syndromic surveillance system using electronic health records (EHR) and predictive analytics to provide just-in-time training for health care providers. Researchers successfully developed data pipelines from UW Health emergency department (ED) EHR data and validated them at Marshfield Clinic. Analysis of the data revealed an increase in acute respiratory infection (ARI) cases during the COVID-era, and predictive models performed well in predicting ARI arrivals and boarders ​(patients admitted to the hospital who remained in the ED for a minimum or four hours after admission). The Wisconsin Real-time Emergency Department Surveillance and Responsive Training (WIRED-RT) COVID-19 Simulation Curriculum Toolkit was developed to help health care teams prepare for surges in cases, focusing on key care scenarios.
