Investigating the Cholinergic Contribution to Gait Dysfunction in Parkinson's Disease
Recruiting
People with Parkinson's disease often experience problems with 'gait' and balance. Gait refers to the way a person moves while walking, such as their speed and length of steps. People with Parkinson's may experience slowness of movement, shuffle their feet, or have periods of 'freezing', during which their feet feel like they are stuck to the floor. Some people may struggle to maintain their balance and fall. These symptoms are frequently disabling and can lead to a worse quality of life. The ne... Read More

Assessment of Neurodevelopmental Needs in Duchenne Muscular Dystrophy
Recruiting
Duchenne Muscular Dystrophy is a genetic disease that causes progressive muscle weakness. There is now substantial evidence that boys with this disease do not demonstrate age-related gains in their cognitive skills. The goals of this study are (i) to use a technology-enabled neurobehavioral assessment called National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) to assess brain development over time; (ii) engage with key-stakeholders to understand how neurodevelopmental problems lik...

Young Adult Eating Habits
Recruiting
Most individuals with obesity become so before age 35 and adolescent's unhealthy dietary patterns, specifically high intake of ultra-processed foods and poor overall diet quality, may contribute to energy overconsumption and weight gain. The overall objective of this research is to establish proof-of-concept for altered reward processing measured by brain response to ultra-processed foods, an increase in ad libitum energy intake, and adverse effects on executive function in response to an ultra-...

Organic Compounds and Postoperative Delirum
Recruiting
This study involves collecting exhaled breath containing hundreds of volatile organic compounds (VOCs) that are present in very low quantity (parts per billion). VOCs in the exhaled gase carry information to indicate individual's risk for Postoperative Delirium and its severity. Our long-term objectives are to identify breathomic patterns for prediction, early detection, and stratification of POD during pre- and post-operative phases.

Effect of Dapagliflozin on Microvascular Function in Women with Symptoms of Coronary Artery Disease
Recruiting
The goal of this clinical trial is to test the effects of a drug (in the drug class called sodium-glucose cotransporter 2 inhibitors) in women who have symptoms of ischemic heart disease. The main questions the study aims to answer are: Does blood flow in the heart improve with study drug? Participants will be randomly assigned to a 12-week course of the study drug, dapagliflozin 10mg, or placebo. Blood flow in the heart will be assessed using stress cardiac magnetic resonance imaging at basel... Read More

Tracking a Tactile Signal Along the Nervous System

Gut Microbiome and Blood Indices in Patients with AD and Their Spousal Caregivers
Recruiting
Spousal caregivers of Alzheimer's Dementia (AD) patients have an elevated risk of developing AD in the future. Past studies have shown the presence of serum indicators correlated with gut biome dysfunction in AD patients. We hypothesize that the same gut biome dysfunction may be present in spousal caregivers of AD patients.

Magnesium and Riboflavin Treatment for Post-Concussion Headache
Recruiting
This clinical trial will try to determine if the supplements magnesium and riboflavin will reduce the pain and duration of headaches in persons diagnosed with a concussion. The participant will be randomized to either active magnesium and riboflavin capsules or placebo (inert) capsules. The capsules will be taken once a day for 14 days. The participant will also complete a short diary form for the 14 days and will have 3 follow up visits either by telephone or in person.

The goal of this observational study is to develop a blood test that may be predictive of postpartum depression. This Blood test is investigational and not yet FDA approved. Participants will not receive the results of this blood test. Up to 500 pregnant women will be recruited for the study from 2 sites. Participants must be age 18 or above with a singleton pregnancy and able to provide written consent in English. The Objective of this Clinical Trial is to prospectively validate the Enlighten...

Non-Nutritive Sweetener Consumption and Glucose Homeostasis in Older Adults With Prediabetes
Recruiting
Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of sucralose, but not aspartame, in m... Read More
