The purpose of this study is to lower the rate of type 2 diabetes in rural Appalachia youth due to obesity and/or being overweight. Our long-term goal is to improve the health of underserved, high-risk youth.
This study will test the effectiveness of the Mentored Planning to be Active + Family on physical activity outcomes and health outcomes among rural Appalachian middle school aged youth suffering from either overweight or obesity.
We have local high school-aged teen mentors work closely with middle school youth to increase social support, self-efficacy, and self-regulation skills to sustain physical activity and improve health before the children enter high school.
The peer mentoring is followed by a 6-month family reinforcement program.
Some parents will provide child assessment data of perceived child physical activity behaviors and child health.
- Child has access to a computer or tablet device at home for virtual mentoring sessions/meetings
- Child suffers from overweight or obesity - does not need to be under the care of a health care professional for this condition
- Child and Parent able to participate read English at a 4th grade level.
- Family not expected to move from rural Appalachia within the 18 months.
The purpose of this study is to improve hemoglobin A1c levels in patients with type 2 diabetes experiencing food insecurity.
The study will examine the effects of a produce referral program alone and in combination with other interventions. Our research is designed to develop a deeper understanding of how to provide patients with type 2 diabetes that are experiencing food insecurity with the resources, skills, and education to manage their health and social needs.
- Age 18 years and older
- Type 2 diabetes based on American Diabetes Association Criteria

The purpose of this study is to find out if taking one medication Diovan (valsartan) or a combination of two medications (valsartan and sacubatril) in one pill called Entresto, will improve prediabetes in Blacks /African Americans over the course of 6 months. We will also look for changes in blood pressure and blood vessel stiffness throughout the course of the study in order to better understand how these medications may impact prediabetes.
Inclusion Criteria: - African American aged 18-65 years old - History of impaired fasting glucose - Impaired glucose tolerance - A1c 5.7-6.4% or other risk factors for diabetes Exclusion Criteria: - Type 2 diabetes - Systolic blood pressure greater than 150/100 or medications to lower your blood pressure - Systolic blood pressure less than 100/60 - Steroid use - Hyperkalemia (high potassium levels)
The aim of this study is to improve mood and diabetes-related outcomes for those with type 2 diabetes mellitus (T2DM) AND symptoms of depression. The present study will examine the effect of mindfulness-based cognitive therapy (MBCT) on symptoms of depression and diabetes.
Your participation in this study will last 8 weeks.
You may qualify if:
• You are between the ages 18-75

The purpose of this research study is to better understand the role of fat tissue, how cells in fat tissue communicate, and determine what signals specific cells use to cause inflammation and insulin resistance during weight gain. This may help researchers better understand the process that happens in Type 2 Diabetes.
As a result, through the course of six--nine weeks, participants will be asked to gain at least 10% of their starting body weight. A dietitian will meet with participants to give advice to help with meeting the study weight gain goals, as well as provide additional meal vouchers and supplemental shakes as needed. Following the study, participants will receive guidance how to lose the weight they've gained if they would like to do that.

This research study is for those who have nonalcoholic steatohepatitis (NASH) (meaning your liver is swollen and damaged because of a buildup of fat in your liver) and some liver fibrosis (which is damaged and scarred liver tissue). Because of your condition, you may be eligible for a research study on an investigational drug for your condition. The Regenerate Study will assess the safety and effectiveness of the investigational medication obeticholic acid (OCA) compared to placebo in delaying specific medical conditions or health related issues that can occur in patients with nonalcoholic steatohepatitis (NASH) (meaning your liver is swollen and damaged because of a buildup of fat in your liver) and some liver fibrosis (which is damaged and scarred liver tissue).
- Age 18 or older
- Diagnosed with Stage 2 or 3 NASH (nonalcoholic steatohepatitis--meaning your liver is swollen and damaged because of a buildup of fat in your liver) and some liver fibrosis (which is damaged and scarred liver tissue).
If you are eligible and decide to take part in this research study, you will need to complete 1 or 2 screening visits to see if you are eligible to participate in the study. Once the study doctor determines you can participate in the study, you will be asked to come back to the clinic 8 times (for the Month 0 [Day 1] Visit, the Month 1 Visit, the Month 3 Visit, and then every 3 months) for the first 18 months you are in the study and then 2 times per year (every 6 months) for each additional year you are in the study.
