Electrophysiology of Fetal Arrhythmia (fMCG)

Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow the investigators to evaluate fetal magnetocardiography (fMCG) as a new tool for the study of normal and abnormal fetal heart rate and rhythm.

Mechanisms of Cerebrovascular Control

The objective of this study is to identify insulin-specific cerebral blood flow (CBF) control mechanisms, and establish cerebrovascular responsive baseline in younger (18-45 yrs) metabolic syndrome adults (MetSyn) who are at substantial risk of stroke and other types of cardiovascular mortality even if they never develop diabetes. The central hypothesis is that vasodilator actions of insulin are impaired in MetSyn due to loss of dilator and gain of constrictor signals. This study will focus on 2 mechanisms that likely limit CBF in MetSyn: 1) Disruption of nitric oxide (NO) vasodilation, and 2) Exaggerated endothelin (ET-1) constriction. Three specific aims will be addressed: Aim 1: To test the hypothesis that physiologic surges of insulin acutely increase CBF in young adults, but adults with MetSyn exhibit paradoxical insulin-mediated vasoconstriction. Aim 2: To test the hypotheses that key mechanisms responsible for poor CBF in MetSyn are shifts in NO and ET-1 signaling. Specifically, in healthy controls, NO mediates robust dilation, with little to no ET-1 constriction. In contrast, adults with MetSyn exhibit uncoupled NO synthase (NOS) and exaggerated ET-1 constriction. Aim 3: To test the hypothesis that insulin regulation of CBF is regionally distinct (e.g. Middle Cerebral Artery (MCA) reactive than Anterior Cerebral Artery (ACA) or basilar), and the negative effects of insulin resistance (IR) are similarly regionally specific.

Peripheral Vasodilation in Obese Humans (ObeseDilate)

The growing population of obese adults is predicted to create a large public health burden in the next few decades. This study examines function of small blood vessels providing blood flow to skeletal muscles, to test if younger obese individuals (≤40 years old, BMI >30) are already displaying reductions in blood vessel function. This study will test if the signals blood vessels use to increase blood flow are changing in these same subjects. Findings from this study may help create treatments to delay or prevent some of the negative effects of obesity on vascular health.

Mixed Methods Investigation of Chronic Facial Paralysis in Individuals With Synkinesis

This proposal will prospectively assess the social, physical, and emotional recognition function in participants with synkinesis. It will measure the effectiveness of neuromuscular retraining therapy to improve muscle coordination compared to chemodenervation, the more established treatment modality, in a single-blinded, randomized control trial using clinician- and patient-reported outcomes measures. The hypothesis tested is that participants undergoing neuromuscular retraining therapy will achieve greater improvement on clinical outcome measures as compared to participants receiving chemodenervation. In this clinical trial, 36 participants undergoing treatment for synkinesis will be enrolled into one of two treatment arms: chemodenervation or neuromuscular retraining therapy. Participants can expect to be on study for approximately 8 months. Participants who enroll in this mixed methods investigation will be recruited from patients of the University of Wisconsin Facial Nerve Clinic and also be enrolled in a another study for assessment [Perception of Emotion Expression in Clinical Populations with Facial Paralysis, IRB approval 2015-0366].

Longitudinal Evaluation of Amyloid Risk and Neurodegeneration - the LEARN Study (LEARN)

The LEARN study a multicenter, observational study will that will evaluate the rate of cognitive change in approximately 500 clinically normal older individuals who "screen-fail" for the A4 trial on the basis of their screening PET imaging not demonstrating evidence of elevated amyloid accumulation (Aβ negative) but meet all other A4 study eligibility criteria. This study will leverage the A4 infrastructure and maximize the data acquired in screening a large number of well-characterized older adults for the A4 trial. The LEARN observational cohort will provide a critical comparison group for the A4 placebo arm, and future trials in preclinical AD. Although accumulating longitudinal data suggest that older individuals with elevated Aβ burden are at increased risk of cognitive decline, it is important to demonstrate a differential rate of clinical decline between Aβe ("Aβ elevated") and Aβne ("Aβ not elevated") individuals on a standardized set of clinical outcomes. Over 2000 well-characterized, highly motivated older volunteers will "screen fail" for the A4 trial. The LEARN study will follow 500 of these individuals, matched as closely as possible to the two treatment arms, in this observation cohort. The LEARN study may selectively recruit from a specific range of SUVr that fall below the threshold for "elevated amyloid" in order to support analyses of the relationship of baseline SUVr to subsequent cognitive change and amyloid accumulation. The observational cohort will be followed for 384 weeks with identical clinical/cognitive testing performed every 24 weeks, running parallel to the A4 treatment study and open label extension.

SHIELD Study: Using Naso-oropharyngeal Antiseptic Decolonization to Reduce COVID-19 Viral Shedding (SHIELD)

Essential workers in positions with increased likelihood of exposure to SARS-CoC-2 will be most impacted by the proposed project. Evidence has shown that the SARS-CoV-2 novel coronavirus is easily transmissable through close contact between individuals, especially during aerosol-generating procedures such as intubation of patients. The intervention proposed in this study (nasal and oral decontamination with povidone-iodine and chlorhexidine, respectively) presents an opportunity for a safe, effective, and feasible treatment to decontaminate the primary entry points for SARS-CoV-2. As such, the intervention to be studied in this project may protect healthcare and other essential workers by preventing transmission of SARS-CoV-2 from patients to healthcare workers, as well as the general public to essential worker,. and thus reducing the incidence of COVID-19 in these workers.

Early Detection of Vascular Dysfunction Using Biomarkers From Lagrangian Carotid Strain Imaging

The purpose of this research is assess imaging and identification of soft plaque that undergoes large deformations or strain will identify plaque vulnerable to rupture which could lead to 'silent strokes'. Validation of current study results with MRI will foster use of real-time ultrasound (US) strain imaging and strain indices as a screening tool for identifying normal human participants susceptible to increased vascular aging and developing plaque prone to rupture or micro-embolization. Current research will evaluate Lagrangian carotid strain imaging (LCSI) for prediction of vascular health on volunteers. In this study, investigators will evaluate age-related strain variations (due to plaque deposition) in the carotid artery, establishing groundwork that will help identify typical and atypical values for these indices. Investigator's hypothesis is that plaques with higher strain indices (softer plaques) are more prone to rupture than plaques with lower strain indices (stiffer) plaques, thus requiring intervention. Clinical criteria for treatment has focused primarily on the degree of stenosis. Long-term objectives are to provide non-invasive methods for screening participants at risk for vascular aging or plaque rupture in asymptomatic participants, expanding upon current criteria for risk assessments based on focal transient ischemic attack (TIA) or strokes. Variations in vessel strain have been associated with, or are precursors to, plaque deposition, vascular aging, or cerebrovascular diseases. Increased arterial strain and pressure changes have been linked to brain aging using magnetic resonance imaging (MRI) based vascular indices, and memory deficits commonly linked to Alzheimer dementia. Stiffening and thickening of the arterial walls have also been associated with cerebrovascular disease. Investigators hypothesize that strain indices as vascular biomarkers can be utilized for screening possible 'vulnerable participants' validated with MRI, with the potential ability to improve endothelial function and reverse vascular aging. Strain indices may enable differentiating study participants with vascular cognitive impairment (VCI) from other dementias. Cognitive testing is unable to make this differentiation.

Antecedent Metabolic Health and Metformin Aging Study (ANTHEM)

Aging is the number one risk factor for the majority of chronic diseases. There are no pharmaceutical treatments to slow aging and prolong healthspan. The anti-diabetic drug metformin is considered a likely pharmaceutical candidate to slow aging. In this study, the investigators hypothesize that metformin treatment in subjects free of type 2 diabetes will improve insulin sensitivity and glucoregulation in insulin resistant individuals, but will decrease insulin sensitivity and glucoregulation in insulin sensitive subjects. Further, the investigators hypothesize that long-term metformin treatment will remodel mitochondria in a way that decreases mitochondrial function in subjects that are insulin sensitive, but improves mitochondrial function in subjects that are insulin resistant. The investigators will use a dual-site, 12- week drug intervention trial performed in a double-blind, placebo-controlled manner on 148 subjects recruited from two separate sites (Oklahoma Medical Research Foundation (OMRF) and University of Wisconsin-Madison (UWM)). After consent and initial subject screening for chronic disease, subjects will be stratified to insulin sensitive (IS) or insulin resistant (IR) groups. Over a 12- week intervention, half of each group will take metformin and half will take a placebo. Pre- and post--intervention, subjects will complete a series of procedures to assess insulin sensitivity, glucose regulation, and biomarkers of aging. The same subjects will provide a skeletal muscle biopsy pre-- and post-intervention to assess the change in mitochondrial function and mitochondrial remodeling with and without metformin treatment. By completion of this project, the investigators expect to provide evidence that helps further delineate who may benefit from metformin treatment to slow aging.

COVID19 SARS Vaccinations: Systemic Allergic Reactions to SARS-CoV-2 Vaccinations (SARS)

Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: - To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a High-Allergy/Mast Cell Disorder (HA/MCD) population, and - If the risk in the HA/MCD is demonstrable, to determine whether the proportions are higher in the HA/MCD in comparison to a representative population without severe allergies or mast cell disorders

Pilot RECAP Study in Healthy Normal Volunteers (RECAP)

The primary objective of the RECAP Study Program is to investigate the role played by conscious experience in the antidepressant effects of the psychedelic agent psilocybin. This pilot dosing study (PILOT RECAP) is designed to determine the optimal dose of midazolam that allows a psychedelic experience to occur while inducing amnesia for the experience. This is an essential step required for subsequent evaluation of the role of memory for the psychedelic experience in the antidepressant effects of psilocybin in the full RECAP study.
