Modeling Basal Forebrain Cholinergic Vulnerability in Down Syndrome
Year Awarded:
2019
Down syndrome, also known as trisomy 21, is a condition that impacts the brain’s development of neurological pathways resulting in mild to moderate intellectual disability and middle age onset of Alzheimer’s disease. Basal forebrain cholinergic neurons (BFCNs) are crucial in mediating cognitive performance and memory throughout the lifespan, and they are particularly susceptible to degeneration in individuals with Down syndrome. This project sought to explore the mechanisms that underlie BFCN vulnerability in Down syndrome and looked specifically for observable and age-related markers of BFCN dysfunction in trisomy 21. The results showed similar levels of Alzheimer’s-related proteins in the BFCNs of individuals with and without Down syndrome, despite the fact that people with the condition have an extra gene copy that produces these proteins. The research team identified that trisomy 21 BFCNs had elevated levels of aging markers which may contribute to the intellectual disability and middle age onset of Alzheimer’s disease in people with the condition.

Evaluating a Novel Follow-up Intervention to Improve the Delivery of Follow-up Care for Low-Risk Breast Cancer Survivors in Wisconsin
Year Awarded:
2022
This project, Evaluating a Novel Follow-up Intervention to Improve the Delivery of Follow-up Care for Low-Risk Breast Cancer Survivors in Wisconsin, will implement a novel patient-centered intervention, known as REASSURE, to optimize the delivery of follow-up care to early-stage breast cancer survivors who are at low risk of recurrence. Early-stage survivors comprise 60% of Wisconsin’s more than 70,000 breast cancer survivors. This intervention is designed to better prepare and support early-stage breast cancer survivors while also reducing the burden of unnecessary medical visits that are especially difficult for patients who are socioeconomically disadvantaged or reside in rural areas. The study has the potential to advance cancer care more broadly through adaptation to other cancers where frequent follow-up clinic visits have limited benefit.

Leaving Prison and Connecting With Medical Care: Medicaid Expansion, Treatment Access and Outcomes for Opioid Use Disorder and Hepatitis C Infection
Year Awarded:
2018
This project, Leaving Prison and Connecting with Medical Care, aimed to evaluate the impacts of two changes to Wisconsin Medicaid policy on health care access, health outcomes and reincarceration for formerly incarcerated individuals. Incarcerated populations have high rates of hepatitis C virus (HCV) and opioid use disorder (OUD), and untreated HCV and OUD lead to severe health and social consequences. Medicaid coverage could reduce adverse health outcomes and reincarceration in former prisoners by improving access to treatment. In 2014, Medicaid eligibility was extended to all poor adults, and in 2015, pre-release Medicaid enrollment assistance was introduced within state prisons, though there has been little research done to assess the effects of these changes on criminal justice-impacted individuals.
The project successfully achieved its goals, demonstrating that expanded eligibility and pre-release enrollment assistance increased the number of Medicaid applications before and enrollments at the time of release. The policies improved coverage for both the general population and those with histories of substance use, and they were associated with a 2.5 percent decline in reincarcerations and a 5.2 percent increase in employment procurement. Additionally, the changes to Medicaid policy significantly increased the likelihood of outpatient visits post-release for individuals with substance use histories, although overall substance use disorder-related care remained low.

Prevention of HPV-Associated Anogenital Cancers Using HIV Protease Inhibitors
Year Awarded:
2020
Human papillomavirus (HPV) is the most commonly sexually transmitted disease in the United States – an estimated 79 million Americans are currently infected— and the number one risk factor for developing anogenital cancers, such as squamous cell carcinoma of the anus (SCCA). In Wisconsin, HPV-positive SCCA disproportionately affects underserved populations, particularly those living with HIV. Once HPV-driven anal pre-cancers are diagnosed, there are few treatment options that are effective or well-tolerated. This project builds on recent findings that show select FDA-approved protease inhibitors, previously used orally to treat HIV infection, can also be used topically to prevent HPV-associated cancers, in particular SCCA.
This team of interdisciplinary researchers will work to determine the molecular mechanisms supporting these effects and repurpose these drugs as an approach for anal cancer prevention in Wisconsin. The long-term goal of this research is to develop a new strategy to prevent HPV-associated cancers, particularly SCCA, especially in high-risk patients such as people living with HIV. This project also includes collaborators from UW–Madison.

Advancing Health Equity for Lupus Patients in Wisconsin: How a Care Continuum and Community Stakeholders Can Inform Interventions to Close Disparities Gaps
Year Awarded:
2020
Lupus is one of the most common autoimmune diseases, causing lifelong burden for 1.5 million U.S. and 28,000 Wisconsin residents. Currently, gaps in care for people with lupus contribute to more kidney failure, more cases of early death, and greater disease damage. Notably, in the US, those with lupus who are Black suffer greater disease burden when compared to other countries, likely indicating disparities in the U.S. healthcare system. Research shows that similar care gaps, disparities, and negative health consequences experienced by people with HIV were reduced by more than 20 percent through targeting key steps to control the disease: diagnosis, linkage to care, retention in care, retention on therapy and low disease activity/ damage to body.
Using cutting-edge gap-closing data analysis methods, Dr. Bartels, Dr. Elwert and team will first study retention in care and retention on immune therapy, and then will further examine gaps and predictors in all five key steps for lupus care to identify which steps offer the most potential to eliminate health disparities and improve outcomes. Healthcare and patient partners will help select, adapt and pilot-test strategies that successfully reduced HIV outcome disparities. The results will provide a foundation for future studies to improve damage-free survival and health equity for people with lupus. This project includes collaborators from UW–Madison and the Medical College of Wisconsin.

UW Innovations in Malignancy Personalized Advanced Cell Therapies (UW-IMPACT)
Year Awarded:
2018
This project, led by Jacques Galipaeu, MD, aimed to to generate the data needed to secure Investigative New Drug licenses from the Food and Drug Administration (FDA) to use personalized GIFT4 B cells to treat cancer as part of first-in-human clinical trials at the UW Carbone Cancer Center. Previous work enabled researchers to convert normal mouse B cells to cancer-killing cells by treating them with a synthetic cell-signaling protein called GIFT4, and the resulting cells were able to initiate an anti-tumor immune response even in the absence of defined tumor markers. In this work, researchers tested these GIFT4 B cells in mice with prostate and neuroblastoma tumors to see if the cells could improve the immune system’s ability to fight cancer.
The researchers made significant progress toward their goal. They found that B cells, when grown with dendritic cells and exposed to GIFT4 protein, could activate T cells which then target tumors. These findings demonstrated the importance of understanding B cell-dendritic cell interactions to advance cancer vaccine development. Additionally, combining GIFT4 B cells with radiation and immunotherapies improved survival, highlighting the efficacy of multifaceted therapies in targeting cancer. Overall, these results have the potential to enhance cell therapies leading to more effective treatment strategies for cancer in the future.

Evaluating COVID-19 Response Efforts to Improve Health and Racial Equity in Milwaukee County
Year Awarded:
2021
This project, led by the UW Population Health Institute, aimed to analyze data relating to Milwaukee County’s rapid dissemination of $77.4 million in COVID-19 relief funding in order to assess investments addressing social determinants of health and racial equity strategies. Milwaukee County was the first municipal government in the country to declare racism a public health crisis and was among the first to collect race and ethnicity data that helped guide efforts to prevent the spread of COVID-19 in communities of color.
The project team successfully assessed Milwaukee County’s investments in social determinants of health and racial equity strategies, collaborating with county leaders and analyzing funding data from state claims and federal expense reports. Their analysis showed that Milwaukee County made significant efforts to ensure equity for marginalized populations affected by COVID-19, particularly through the $12 million Small Business Recovery Grant program. This program distributed grant monies to minority, woman and veteran-owned businesses, with 66% of the 1,551 grant recipients falling into these categories. Additionally, the Milwaukee County Department of Administrative Services Economic Development Division created an interactive map to visualize the locations of funded businesses.

Comparison of Successful Colorectal Cancer Screening Strategies in Wisconsin Rural and Urban Settings: Achieving “80% In Every Community”
Year Awarded:
2019
This project, led by Dr. Jennifer Weiss, aimed to characterize factors at the system, clinic, provider and patient levels that influence colorectal cancer (CRC) screening rates at rural and urban clinics. CRC is the second leading cause of cancer-related deaths for adults in Wisconsin, and it the most preventable yet least prevented cancer due to low uptake of screening. Recognizing that many rural, low-income, and racial/ethnically diverse communities have disproportionately low screening rates, the National Colorectal Cancer Roundtable announced a campaign to achieve screening rates of 80 percent and higher in every community. Wisconsin has a screening rate of 73.4 percent; however, there is wide geographic variation among rural and urban clinics.
The research team successfully developed a novel rural-urban geodisparity model that revealed significant disparities in CRC screening rates between rural and urban clinics. High-performing clinics, particularly those serving subpopulations with historically low screening rates, utilized stool-based screening tests more frequently, likely due to fewer resources and less access to colonoscopy facilities in rural areas. Additionally, the research team conducted interviews with clinic staff who highlighted the critical roles of medical assistants and primary care providers, shared decision-making and the need for stratified screening rate information to inform interventions aimed at reducing disparities and improving CRC screening practices.
