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.

Frailty and Dysphagia in Older Adults

The purpose of this research study is to figure out if there are physical factors such as cognition level, nutrition status, walking speed, and handgrip strength that are associated with the development of swallowing problems. Investigators want to better understand how swallowing problems develop in older adults with and without frailty. Identifying factors that contribute to swallowing problems, can develop therapies in the future to improve swallowing outcomes for older adults. This study will be done at the University of Wisconsin-Madison (UW-Madison). A total of about 69 people will participate in this study.

An Observational Study of the Progression of Intermediate Age-Related Macular Degeneration

This is a multicenter prospective study in participants with intermediate age-related macular degeneration (iAMD). One primary objective of this study is to assess iAMD disease progression, by the timeline and rates of conversion for high-risk iAMD at baseline to more advanced atrophic AMD stages. The other primary objective of this observational study is to assess the feasibility of measuring the rate of photoreceptor loss as a potential clinical endpoint. The study will consist of an observation period of approximately 3 years (~144 weeks) for participants.
