For 19 years, the Centers for Disease Control and Prevention-funded Arizona Prevention Research Center (AzPRC) has been engaged in academic community collaborative research to reduce chronic disease health disparities among the Latino border communities in Arizona. Our research project, Unidos: Linking Individuals' to Social Determinant and Community Health Services, will result in a model Community-Clinical Linkage intervention to reduce chronic disease risk among Latinos in Arizona. Further, the investigators expect this intervention model to be applicable in other regions and populations. To execute this research, the AzPRC will implement the intervention in partnership with county health departments and Federally Qualified Health Centers. In Unidos the county/community-based CHWs will: 1) support and connect participants to health promotion resources; 2) provide individual and group-based support guided by a novel framework for understanding Latino's health advantages, the sociocultural resiliency model; and, 3) leverage community resources to help individuals address SDH-related needs.

Currently, in clinical practice there has been no standardization in the number of injections a single dose of intradetrusor onabotulinumtoxin A is administered in. Given the increasing use of this treatment modality, the aim of this study is to compare outcomes for patients given a 100 unit dose of onabotulinumtoxin A split into 5 as compared to 20 injections for the treatment of overactive bladder or urgency urinary incontinence refractory to medical treatment.

The ELASTO-SURGERY study aims to evaluate the prognostic role of portal hypertension evaluated by non-invasive methods in predicting post-operative morbidity (at 90 days) and mortality (at 365 days) in patients with advanced chronic liver disease undergoing elective extrahepatic surgery. Read Less

Hyper polarized Xenon-129 MRI will be directly compared to a radioactive Xe-133 scintigraphy to detect defects in lung ventilation from airflow limitation. This study is conducted as a pilot study with intention to conduct a larger clinical trial. Read Less

For patients who have been diagnosed with pancreatic cancer that has not spread outside of the pancreas and nearby lymph nodes. The purpose of this research study is to understand if we are able to detect pancreatic cancer DNA in the blood stream before, during, and after treatment. Read Less

This study aims to better understand how people with Parkinson's control reaching movements. Specifically, we are asking how these individuals respond to different environmental perturbations. Testing includes reaching movements made within a virtual reality set-up. Read Less

The overarching goal of this Pain Management Collaboratory Demonstration project is to test a new Whole Health paradigm for chronic pain care, emphasizing non-pharmacological pain self-management that is hypothesized to reduce pain symptoms and improve overall functioning and quality of life in Veterans. In UH3 Aim 1, the investigators will conduct a 12-month pragmatic effectiveness trial at 5 VA sites across the country to test whether veterans with moderate to severe chronic pain randomized to receive the Whole Health Team (WHT) intervention are more likely than those receiving Primary Care Group Education (PC-GE) to: Hypothesis 1: Experience improved pain interference (primary outcome), pain intensity, functioning and quality of life (secondary outcomes); Hypothesis 2: Decrease use of higher-risk pain medications, including opioids, or high-risk combinations; Hypothesis 3: Engage in a greater number of non-pharmacological pain management activities; and Hypothesis 4: Experience improved mental health-related symptoms, including sleep problems and suicidality. In addition, both the WHT and PC-GE arms will be compared to a third group of veterans randomized to Usual Primary Care (UPC, Control) on the same primary and secondary outcomes above. After the baseline assessment, masked telephone assessments will be administered to participants at 3, 6, 9, and 12 months. UH3 Aim 2 is to conduct a process evaluation of the two active interventions (WHT and PC-GE) and a budget impact analysis that includes costs to implement and execute the two active interventions as well as the control condition (UPC) to inform the development of an implementation toolkit for scaling and dissemination. Eligible participants are veterans reporting moderate to severe chronic pain present every day or nearly every day for ≥ 6 months. The total sample size for the population is based on our main study aim/hypothesis and is N=745. This breaks down to n=341 in each of the active interventions (WHT and PC-GE) and N=63 in the Usual Primary Care arm (Control). Results of this UG3/UH3 Pain Management Collaboratory Demonstration project will contribute to the overall mission of the NIH/VA/DoD initiative to build national-level infrastructure that supports non-pharmacologic pain management in veterans and military service personnel.

The Atlas of Retinal Imaging in Alzheimer's (ARIAS) study is a 5-year study examining the natural history of retinal imaging biomarkers associated with disease risk, disease burden, and disease progression in Alzheimer's disease (AD). The objective of this project is to create a 'gold standard' reference database of structural anatomic and functional imaging of the retina, in order to enable the identification and development of both sensitive and reliable markers of AD risk and/or progression. Our ultimate goal is to develop a new screening protocol that identifies changes related to AD 10-20 years before AD is clinically visible. Read Less

This study proposes to evaluate the therapeutic efficacy, immunologic effects and normalization of laboratory parameters for patients at high risk for mortality when infected by SARS-CoV-2 (COVID-19) when administered one unit (approximately 200 mL) of convalescent plasma administered over a period of one hour. Following administration of the convalescent plasma, physical exam/clinical assessment information is collected daily and routine lab result data is collected every three days. Read Less

This is an observational study of children and young adults ages 6-20 years with type 1 diabetes and age- and race-matched controls. The investigators will be examining blood and urine hormone levels as well as measures of bone density including DXA and high-resolution peripheral quantitiative computed tomography. The investigators will also be collecting data regarding physical activity via use of wearable accelerometers. The investigators hypothesize that youth with type 1 diabetes will have slower bone accrual and impaired bone microarchitectural integrity compared with non-diabetic controls, and that bones of individuals with type 1 diabetes will not respond as well to physical activity. The investigators hypothesize that poor bone accrual will be associated with sub-optimal glucose control as well as lower levels of insulin-like growth factor 1. Read Less
