Team-Based Shared Decision-Making Program in Cardiovascular-Kidney-Metabolic Health

The investigators are proposing a new team-based shared decision-making (SDM) program. The goal of this study is to see whether this program is practical and whether it may help adults with cardiometabolic risk factors and cardiovascular-kidney-metabolic syndrome. The investigators will enroll adults from a primary care clinic in Maryland. People in the intervention group will take part in the 6-month program in addition to usual care. People in the control group will receive usual care only.

Diet Order Effects of Low Fat vs. Low Carb Diets on Body Fat Change

Background: In a previous study, participants were lived at the NIH and randomly received either a low-fat or a low-carbohydrate diet for 2 weeks and then switched to the other diet for 2 more weeks. Participants who received the low-carbohydrate diet first lost more body fat at the end of the study than those who received the low-fat diet first. Researchers want to see if they can repeat that result in a longer weight loss study when participants live at home. Objective: To test the effects of diet order in people receiving either a low-fat or low-carbohydrate diet first for 4 weeks and then immediately switched to the other diet for another 4 weeks. Eligibility: Adults aged 19 to 50 years with a body mass index of 25 or more. Design: Participants will complete the study at their homes, but there will be 3 required visits to the NIH. Participants will drink a special type of water 2 weeks before the baseline NIH visit and collect urine samples at home to measure how many calories they burn. Before the diets begin, participants will visit the NIH for baseline testing when they will have a metabolism test while relaxing in a bed with a plastic hood over their head to collect the air they breathe out. They will have scans to measure their bone density and how much muscle and body fat they have. They will give stool, blood, and urine samples. Participants will be asked to eat a specific diet for 4 weeks followed by a different diet for 4 weeks. All meals will be delivered to the participants' homes. They will eat only the foods delivered. Participants will weigh themselves daily. They will wear a monitor to track their physical activity and a sensor to measure their glucose levels. They will prick their finger each morning to test a drop of blood for ketones. Participants will meet virtually as a group with the study team weekly. Participants will have two more NIH visits towards the end of each diet period....

The Food Intake Phenotype: Assessing Eating Behavior and Food Preferences as Risk Factors for Obesity

The prevalence of obesity in the United States has reached alarming proportions with 33% of adults over the age of 20 being overweight. Obesity is more than twice as prevalent, however, in the Pima Indians of Arizona. Although there have been a number of advances in our understanding of the genetics of obesity, the environmental influences on the genetic expression of obesity requires further investigation. In an effort to understand some of the influences on the high prevalence of obesity in the Pima Indians, the present study was designed to investigate eating behaviors and food preferences, most especially the preference for high fat foods, in sib-pairs of Pima Indians who have been previously genotyped in our genomic scan for loci linked to diabetes/obesity. Most specifically, we will utilize several questionnaires and methods of assessing eating behavior and the preference for high fat foods to create a food intake phenotype. In addition, we will study Caucasians so that comparisons can be made between these two groups. We will make these evaluations by assessing eating behavior, food preferences including usual fat intake and preferences for high fat foods, body image perceptions, and energy expenditure. It is hoped that the data gathered from this study will elucidate some of the risk factors for the development of obesity among the Pima Indians.

Cross-Sectional and Longitudinal Studies of "Pre-Diabetes" in the Pima Indians

Insulin resistance and a defect in early insulin secretion are risk factors for the development of type 2 diabetes mellitus. A recent longitudinal analysis which tracked the development of diabetes demonstrated that both insulin action and early insulin secretion deteriorate as individuals progress from normal to impaired glucose tolerance and then to diabetes. These results suggest that both inherent (apparent in normal glucose tolerant subjects who progress to diabetes and likely to have a genetic basis) and acquired (evident as individuals progress from NGT to IGT to diabetes and possibly environmental in origin) defects in insulin action and secretion contribute to the pathogenesis of type 2 diabetes. To identify the genetic and environmental determinants of diabetes we are continuing to determine: (1) if there are genes that segregate with metabolic risk factors for diabetes which might therefore be genetic markers for type 2 diabetes and (2) the mechanisms mediating genetic and environmental determinants of insulin resistance and impaired insulin secretion. \<TAB\> Volunteers for this study will be admitted to the clinical research ward where they will undergo several tests to determine body composition, oral and intravenous glucose tolerance and in vivo insulin action. In addition, in selected subjects, adipose and/or skeletal muscle tissue will be obtained by percutaneous biopsy for in vitro studies of gene expression and insulin action in these tissues. A transformed lymphocyte cell line will be established for each subject as a permanent source of DNA for genetic studies. Genetic markers for type 2 diabetes and insulin resistance will be sought by typing each individual at positional and functional candidate loci in the hopes of finding an association between these loci and obesity, insulin secretion, insulin resistance and/or type 2 diabetes. ...

A Study to Test Whether BI 3034701 Helps People to Lose Weight Who Live With Obesity or Overweight

This study is open to adults between 18 and 74 years of age and who have a body mass index (BMI) of 30 kg/m2 or more, or a BMI of 27 kg/m2 or more and at least 1 health problem related to their weight. People who have previously not managed to lose weight by changing their diet can participate. People with type 2 diabetes cannot take part in this study. The purpose of this study is to find out whether a medicine called BI 3034701 helps people living with obesity or overweight to lose weight. This study has 7 groups of participants. Groups 1 to 6 get different doses of BI 3034701; Group 7 gets placebo. Placebo looks like BI 3034701 but does not contain any medicine. Every participant has more than an 80% chance of getting BI 3034701. Participants receive 2 injections of BI 3034701 or placebo under their skin for 42 weeks. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 10 months. During this time, they visit the study site 15 times. The study doctors regularly measure the participants' body weight and take necessary laboratory tests. Participants also answer questions about their well-being and note their food intake and physical activity in diaries. The results will be compared between groups of participants to see whether the treatment works. The study doctors also regularly check participants' health and take note of any unwanted effects.

A Study to Learn About the Study Medicine (PF-08653944) in People With Obesity or Overweight and Type 2 Diabetes (T2D)

The purpose of this clinical study is to learn about the safety and effects of the study medicine to help adults with obesity or overweight and type 2 diabetes lose weight. Being overweight or obese means carrying too much body weight. Type 2 diabetes is a condition where there is too much sugar in the blood.

A placebo does not have any medicine in it but looks just like the medicine being studied. The investigators will compare the experiences of people receiving the study medicine to those of the people who do not. This will help us assess if the study medicine is safe and effective. People will take part in this study for about 21 months. During this time, they will have about 14 study visits at the site and 5 over the phone.
