Polyostotic fibrous dysplasia (PFD) is a sporadic disorder which affects multiple sites in the skeleton. The bone at these sites is rapidly resorbed and replaced by abnormal fibrous tissue or mechanically abnormal bone. PFD may occur alone or as part of the McCune-Albright Syndrome (MAS), a syndrome originally defined by the triad of PFD, cafe-au-lait pigmentation of the skin, and precocious puberty. The bony lesions are frequently disfiguring, disabling and painful, and depending on the location of the lesion, can cause significant morbidity. Lesions in weight-bearing bones can lead to disabling fractures, while lesions in the skull can lead to compression of vital structures such as cranial nerves. The natural history of this disease is poorly described and there are no clearly defined systemic therapies for the bone disease. This is a data collection and specimen acquisition protocol. The purpose of the study is to define the natural history of the disease by following PFD/MAS subjects over time and by using in vitro experimentation with samples/tissue from subjects with the disease. Study Objectives 1. Primary Objective Define the natural history of disease by gaining clinical and basic information about PFD/MAS by following subjects clinically and using in vitro experimentation with tissue from subjects with the disease. 2. Secondary Objective Refer eligible subjects for enrollment into other appropriate research protocols, if any are currently active. Study Population The study population will include: 1. Subjects with known or suspected Polyostotic Fibrous Dysplasia (PFD) or in combination with McCune-Albright Syndrome (MAS) 2. Subjects who meet eligibility criteria will be accepted regardless of gender, race, or ethnicity Design This study is an observational/natural history study of PFD/MAS. Outcome Measures Primary 1. Successfully enroll subjects with PFD or MAS for the collection, evaluation and analysis of data obtained from clinical visits. 2. Obtain onsite and offsite research tissue (waste tissue) from patients with PFD/MAS that are enrolled onto this study or from individuals with PFD/MAS that are offsite and willing to donate waste tissue to NIH. Research tissue will be used with existing primary cell culture technology (ongoing in our laboratories) to: - understand the basic bone biology of the pathologic cell (or cells) involved in the lesions of PFD/MAS - determine the presence or absence of mutated cells at "uninvolved sites" to formulate better strategies of predicting the initiation of new lesions, the natural history of lesion progression and/or response to therapy - understand osteogenic differentiation, in particular, the role of G(s)alpha in these lesions, which will be transferable to our understanding of bone biology in general - understand the pathophysiology of FD and/or endocrine lesions - develop better methods of identifying and expanding unaffected bone cells from patients with PFD in an effort to create better grafting material(s) 3. Identify and predict clinical and biological behavior of fibrous dysplastic bone lesions based on: - stability, rate of growth, rate of change, progression and regression, and development of new lesions - differences between cranial, axial and appendicular lesions 4. Define the natural history of the multiple endocrinopathies associated with MAS and the response to standard of care medications 5. Define clinical and biological aspects of the disease not previously identified 6. Generate future research studies related to PFD alone or in combination with MAS Secondary 1) Successfully enroll eligible subjects into active research protocols applicable to the FD/MAS population.

In a healthy person, the production of nitric oxide (NO) by the endothelium, the inner lining of the blood vessel, is responsible for a) the ability of the blood vessel to dilate so it can increase its blood flow and b) act as an anti-clotting product to prevent blood clotting in those vessels. Under physiological stress either due to the development of a disease such as diabetes or simply from aging, the endothelial cells can be impacted and become dysfunctional, thereby impairing their ability to make NO and even promoting the development of blood clots. When such endothelial dysfunction occurs, it may be a precursor for the future development of cardiovascular (CV) disease like hypertension or coronary artery disease later on in life in these patients. Therefore, the ability to enhance the local production or availability of NO within such affected blood vessels in patients identified as prone to endothelial dysfunction could play a positive role in either preventing or delaying the onset of endothelial dysfunction and subsequent CV disease in such patients. RM is an oral supplement consisting of natural ingredients and the amino acid, L-citrulline. In laboratory experiments with cells from the inner lining of blood vessels, the four components of RM have been shown to increase the concentration of NO and decrease the levels of some aging markers. In our recently completed study (manuscript currently in review), 31 young men and women took the supplement for 14 days and had no serious side effects. The supplement caused the expected potentially beneficial dilation of the blood vessels and decrease in the levels of Plasminogen Activator Inhibitor-1 (PAI-1), whose levels correlate with aging and risk of cardiovascular disease. In this study, healthy participants will consume the supplement for a 6-week period to determine if PAI-1 levels continue to be suppressed and also examine whether the supplement has an effect on other blood markers whose levels can change with aging or cardiovascular disease and may also be indicative or predictive of an illness.

Paranoia is a pattern of thinking in which people feel suspicious or believe others may want to harm them. It can occur in many people, not only those with a mental health diagnosis, and it can affect daily life, relationships, and overall well-being. Research has consistently shown that Black Americans report higher levels of paranoia than White Americans, even when they do not have a clinical diagnosis. However, the reasons for this difference are not well understood. The goal of this study is to better understand why these differences exist. In the experimental part of the study, researchers will use a randomized design to test whether exposure to stressful experiences related to race leads to higher levels of paranoia among Black American participants. The study will also examine factors that may strengthen or weaken this effect, such as individual experiences and personal characteristics. By identifying how stressful experiences related to race influence paranoia, this research aims to improve how paranoia is measured and understood across different groups. These findings may help researchers and clinicians use more accurate and culturally appropriate tools to assess psychosis-related experiences in diverse populations.

The purpose of this trial is to learn about the safety and effectiveness of the antibody GEN1079 in participants with certain types of cancer. The trial has multiple parts. The first part of the trial tests different doses of GEN1079 to find out if it is safe and determine what are the best doses to use. The second and third parts continue to test the safety of and whether GEN1079 works in additional participants with specific cancer types and at doses chosen based on results from the previous parts of the trial. For each participant, the trial will last approximately 33 to 67 weeks but this may vary for each person. This includes up to 21 days for screening prior to receiving trial treatment, approximately 6 to 12 weeks of treatment (the duration of treatment may vary for each participant), and approximately 24 to 52 weeks of follow up after trial treatment ends (the duration of follow up may vary for each participant). During the screening, tumor tissue either collected prior to this trial or freshly collected during screening will be provided by all participants. Participation in the trial will require visits to the site, with more frequent visits at the start of treatment and then less frequent visits afterwards. At site visits, there will be various tests (such as blood draws) and procedures (such as recording of heart activity, computed tomography [CT] scans) to monitor whether the treatment is safe and effective. All participants will receive active drug; no one will be given placebo.

This clinical trial studies whether a virtually delivered diet intervention focused on lower added sugar, higher fiber, and higher omega 3 fatty acid (LASO-3) can be used to improve chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors after treatment. Cancer survivors often experience CIPN during and after cancer treatment with neurotoxic chemotherapy. CIPN is characterized by nerve damage from chemotherapy that leads to numbness, tingling, or pain in the hands or feet. However, there are few treatments to manage CIPN. Inflammation contributes to the development of CIPN and dietary patterns that have been demonstrated to improve diet quality and reduce inflammation in cancer survivors may be promising for use as a CIPN management strategy. The LASO-3 diet intervention consists of virtually delivered nutrition education sessions provided by a Registered Dietitian. The sessions focus on three dietary goals, informed by the United States Dietary Guidelines for Americans: 1) lowering added sugar intake to < 10% of daily calories, 2) increasing daily fiber intake to ≥ 20 grams, and 3) increasing intake of moderate-high omega-3 seafood to three or more servings weekly or 3300-3400 mg/day of alpha-linolenic acid (e.g., plant-based sources include canola or flaxseed oil, walnuts, or flaxseed or chia seeds). The Registered Dietitian tailors the sessions to the patient based on information and feedback obtained throughout the sessions. The LASO-3 diet intervention may be an effective way to improve CIPN in cancer survivors after treatment.
