The purpose of this study is to find out what combination of components, if any, offers the best support for keeping weight off after someone loses weight. Long term weight loss maintenance is a challenge for many people who lose weight. There are many strategies, or components, people may use to avoid regain, but investigators do not know if there is a best, or optimal, combination of such components that can be done without adding a lot of cost or other burdens for people. - The primary goal of this clinical trial is to identify the optimal package that maximizes weight loss maintenance. - The study also wants to understand the reasons why these components may work and if certain components help specific sub-groups of people. Participants will engage in a 16-week Phase 1 Weight Loss Program. Participants who lose 5% or more of their weight during that program will continue to Phase 2 Extended Care and be randomly assigned to 0, 1, 2, 3, or all of four methods of weight loss maintenance. They will use their assigned package for 12 months. Researchers will compare 16 different possible combinations of components and learn which of the 16 packages offers the best support for keeping weight off. The four components participants could be assigned to in Phase 2 are: 1. Reduced Food Variety: Limiting the variety of foods participants eat by having them choose a few high-calorie, low nutrient foods to eat regularly 2. Home-based Resistance Training: Engaging in exercises that build strength from the comfort of the participant's own home 3. Buddy Training and Support: Having a friend or "buddy" get trained to support the participant 4. Acceptance and Commitment (ACT) Workshops: Having participants learn skills to handle tough thoughts and feelings about weight control in a healthy way Participants will have their weight measured and complete surveys 4 times if they complete both Phase 1 and Phase 2. During Phase 1, participants will attend weekly group sessions and be in touch with a study staff member investigators call a Wellness Coach. During Phase 2, participants will stay in touch with their Wellness Coach, use their assigned package, and answer questions about their experience periodically.

Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases.

This phase III trial compares the effect of olaparib for one year versus two years, with or without bevacizumab, for the treatment of BRCA 1/2 mutated or homologous recombination deficient stage III or IV ovarian cancer. Olaparib is a polyadenosine 5'-diphosphoribose polymerase (PARP) enzyme inhibitor and may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Giving olaparib for one year with or without bevacizumab may be effective in treating patients with BRCA 1/2 mutated or homologous recombination deficient stage III or IV ovarian cancer, when compared to two years of olaparib.

High blood pressure (hypertension) is a known side effect of the treatment with fruquintinib. Current research does not provide a clear answer whether minority groups such as Black/African American and/or Hispanic/Latino with refractory metastatic colorectal cancer (mCRC) have a bigger risk of higher blood pressure after treatment with fruquintinib. The main aim of this study is to learn how often adults of a minority group experience hypertension after they have been treated with fruquintinib for refractory mCRC. Other aims are to learn how safe fruquintinib is and how well it is tolerated by participants. Participants will receive fruquintinib in 4-week treatment cycles until their condition worsens, they do no longer tolerate the treatment or stop the treatment for other reasons. After the last treatment, participants will be checked upon every 3 months until study completion.

This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. There is some evidence from previous clinical trials that people who have a MammaPrint High 2 Risk result may be more likely to respond to chemotherapy and immunotherapy. Adding durvalumab to usual chemotherapy may be able to prevent the cancer from returning for patients with MP2 stage II-III hormone receptor positive, HER2 negative breast cancer.

During the controlled feeding phase, all food will be provided to the families of the participants for the entirety of the 12 weeks. Participants (n=80) will have been diagnosed with NAFLD based on the presence of current evidence of active disease, which will be determined by the ongoing presence of hepatic steatosis estimated by diffusely echogenic liver via ultrasound suggestive of fatty liver and a serum alanine aminotransferase (ALT) level of 45 U/L or greater. All participants will be children and adolescents age 10-17 yrs.; will have an HbA1c <7.0; and will be overweight or obese (BMI >85th percentile). It is anticipated that most participants will be sedentary. The investigators will inquire as to routine physical activity at screening. All participants will be asked to maintain their usual level of physical activity throughout the study. Physical activity will be monitored via a smart watch provided to each participant at the beginning of the study, and participants will be queried weekly by the study dietitian regarding changes in physical activity. Participants who use oral contraceptives will be asked to maintain consistent use of these preparations throughout the study. Hormone use will be examined as a potential covariate in statistical analyses.
