NYUCI-ES: Psychosocial Intervention to Improve Health Outcomes for Chinese and Korean ADRD Caregivers
This study will conduct a two-arm randomized controlled trial to test the efficacy of a culturally tailored version of the NYU Caregiver Intervention (NYUCI) plus enhanced support (ES) through online chat groups (the NYUCI plus WeChat/Kakaotalk/other social media apps \[popular social media apps for individuals of Chinese or Korean descents\] peer support which we call the NYUCI-ES in reducing health risks for cardiometabolic disease among older Chinese and Korean American adults caring for relatives with ADRD. In collaboration with community organizations across the New York and northern New Jersey metropolitan area, we will enroll 300 caregivers of people with ADRD (150 Chinese and 150 Korean) in this study. Aim 1: Develop culturally adapted informational and educational materials about dementia and caregiving issues for social service providers of the intervention and for family caregivers. Aim 2: Test the hypothesis, H1: A counseling and support intervention (the NYUCI-ES) will significantly improve psychosocial factors such as depression, stress self-rated health and chronic disease management among Chinese and Korean-American ADRD caregivers and these changes will be mediated by improvement in social support. H1a: By the first (6- month) follow-up, the mediators (increases in social support, stress reaction) will improve significantly in the intervention group compared to baseline values and the control group. H1b: These improvements will be maintained, and lead to reduction in depressive symptoms, and improvement in self-reported health and chronic disease self-management by the 12-month follow-up compared to the control group. Aim 3: Test the hypothesis, H2: the NYUCI-ES will reduce biologic risk factors, including metabolic health (glycosylated hemoglobin, BMI) and inflammation (hsCRP, lipid metabolism, etc.) within 6 months of enrollment compared to baseline and a control group; these changes will be mediated through increases in social support and decreases in depressive symptoms and will be maintained at the 12-month follow-up. The public health significance of these findings will likely have an impact on health care policy for CGs from diverse underserved ethnic and cultural backgrounds, potentially reducing morbidity, and improving their quality of life.

The Effects of GLP-1 Receptor Agonists on Chemosensory Function and Ingestive Behavior
The goal of this study is to explore whether of GLP-1 receptor agonist use is associated with differences in taste, smell, food preferences, appetite, food cravings, and responses to food cues in adults. The study includes adults who are not currently taking a GLP-1 receptor agonist but may be eligible to use one, and adults who are already taking a GLP-1 receptor agonist as part of their regular medical care for approximately 1 month or approximately 6 months. The main questions it aims to answer are: Are taste and smell function different among adults who are not taking a GLP-1 receptor agonist and adults who have been taking one for different lengths of time? Are food preferences, appetite, food cravings, food reward, attention to food cues, and salivary responses to food cues different among these groups? Researchers will compare adults not currently taking a GLP-1 receptor agonist with adults taking a GLP-1 receptor agonist for approximately 1 month or approximately 6 months. The research team will not prescribe, assign, or provide GLP-1 receptor agonist medications. People in the study will attend two in-person study visits, complete taste and smell tests, complete food preference and computer-based tasks, and provide saliva samples during a food cue task. Questionnaires about appetite, cravings, food cues, and eating behavior will be completed at home over approximately 2 weeks.

Simplifying Diet Tracking in a Digital Weight Loss Intervention
The purpose of this study is to compare two approaches for tracking dietary intake in a 12-month fully digital weight loss intervention: (1) Simplified approach: track Red Zone Foods (e.g., foods high in calories and low in nutritional value) vs. (2) Detailed approach: track all foods and their corresponding calories. In essence, this is a head-to-head comparison of two tracking approaches; the investigators are evaluating whether weight loss is comparable over 12 months, or whether one approach will have greater weight loss. The investigators will recruit 328 adults. Broadly, adults with overweight or obesity who live in the United States will be eligible. The weight loss intervention will last 12 months. All participants will be asked to track their dietary intake + body weight + steps daily as well as complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1, 6, 12, and 18 months.

Effect of Nicotinamide Riboside on Ketosis, Fat Oxidation & Metabolic Rate
Background: At least 30% of Americans have fatty liver disease. This means that they store too much fat in the liver. At the moment lifestyle changes are the only way to treat this problem. Objective: To test how (1) a low-carbohydrate diet and (2) a supplement called nicotinamide riboside (NR) affect how a person s body uses dietary fat. Eligibility: Men aged 18 to 65 and women aged 18 to 50 who are healthy volunteers with a body mass index (height to weight ratio) of 25 or more. Adults with maturity-onset diabetes of the young type 2 (MODY2) are also needed. Design: Participants with diabetes will have 1 screening visit and a 9-day clinic stay. Healthy volunteers will have 1 screening visit and 2 clinic stays of 1 to 2 weeks each. During screening, all participants will have a physical exam with blood and urine tests. They will have their heart rhythm measured while riding a gym bike. NR is a pill taken by mouth. Only healthy volunteers will take the NR, for 14 days at a time, during 1 clinic stay. During their other stay, they will take placebos; these are pills that look like the study supplement but contain no NR. During each clinic stay, all participants will eat a normal American diet. Then they will eat a ketogenic "low-carb" diet for 5 days. Participants will have many tests, including: Sleeping every night and having two 24-hour stays in a special room that measures the gases their body uses and produces. Drinking a high-fat shake, then remaining seated for 5 hours while their blood and breath are monitored. Having a substance injected into the arm and remaining seated for 3 hours while their blood is measured. Wearing monitors to measure their activity levels. Another monitor will measure their blood glucose levels. Having imaging scans. ...
