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.

When the United States Center for Disease Control (CDC) began encouraging everyone to wear masks to help reduce the spread of COVID-19, many people were unprepared. Some individuals didn’t know how to properly wear a mask while others weren’t able to obtain one. However, evidence continued to mount that proper use of masks was critical to managing COVID-19. Through instructional videos, this project focused on teaching Wisconsinites how to evaluate and properly use the masks that are readily available to them to help protect people from COVID-19. The grant team was successful in developing a mask solution that, if widely adopted, would help lessen the impact of COVID-19. They found that mask fit was crucial for filtering aerosol, which are smaller respiratory droplets, both for inhalation and exhalation. The team created three informational videos focused on the importance of mask fit, how to improve mask fit, and how to choose the right mask. The videos were showcased by several news outlets alongside interviews with the principal investigator; the video Can Your Mask Stop a Cough? – Mask Study using a Laser has over 30,000 views on YouTube as of June 2021.

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.

The Wisconsin Partnership Program at the UW School of Medicine and Public Health (SMPH) has established the Wisconsin Partnership Program Scholarship Program – a four-year scholarship created with the goal of increasing recruitment of medical students at the SMPH from communities that are disproportionately impacted by health inequities and poor health outcomes. Funded by the Partnership Education and Research Committee (PERC), the scholarship program is designed to enhance the recruitment and retention of medical students in Wisconsin, and in doing so, help create and sustain a physician workforce that reflects and keeps pace with Wisconsin’s diverse population.

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.
