Background: Vaccines help the body learn to fight infections. Some vaccines are combined with adjuvants, which are added substances that make vaccines work better. FluMos-v2 is an experimental flu vaccine; ALFQ is an experimental adjuvant. Objective: To test FluMos-v2, with and without the ALFQ adjuvant, in healthy adults. Eligibility: Healthy adults aged 18 to 50 years. They must have received at least one flu vaccine from the 2020-21 season through the 2024-25 flu season. They must also agree not to receive the licensed 2025-26 flu vaccine. Design: Participants will have 12 clinic visits over 15 months. Participants will be screened. They will have a physical exam and blood tests. On 2 visits, about 4 months apart, participants will receive a vaccination. The shots will be given into the muscle of the upper arm. They will get a follow-up call the day after each shot. They will keep a daily diary for 7 days; they will record their temperature and any other symptoms they feel after each shot. All clinic visits will include collection of blood, saliva, and nasal secretions. If participants develop flu symptoms (such as fever, runny nose, sore throat), they will be asked to come to the clinic. About 2 weeks after each vaccination, participants may opt to undergo apheresis: Blood will be taken from the body through a needle inserted into one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a needle in the other arm.

Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: - Blood draws - Psychological tests - MRI: Participants will lie in a machine that takes pictures of their brain. - MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. - Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. - Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.

The goal of this clinical trial is to learn how well two community-based self-management programs work in people with chronic back or neck pain. The main question it aims to answer is: How well does a community-based self-management program teaching mind-body skills such as mindfulness and cognitive behavioral approaches (Partners4Pain) work for reducing pain intensity and interference with general activities and enjoyment of life compared to a community-based self-management program focused on general health and wellbeing (Keys to Wellbeing)? Participants will be asked to do the following: - Attend 2 screening visits to learn about the study and see if they meet the requirements to participate. - Be randomly assigned to one of the two community-based self-management programs. - Attend 9 weekly self-management program sessions (90 minutes each) - Complete surveys about their pain and overall health at 2 months (after the programs end), 4 months, and 6 months. Funding for the project is provided through the National Center for Complementary and Integrative Health (NCCIH) and the National Institute of Neurological Disorders and Stroke (NINDS) through the NIH HEAL Initiative (https://heal.nih.gov/), R33AT012309.

The goal of this study is to learn about how the hormone insulin controls blood sugar in a variety of people. The main question it aims to answer is about how much insulin the body actually needs to maintain a normal blood sugar level. Participants will be asked to come in for a one-day study visit in which they will undergo a "graded insulin suppression test" ("GIST"). The GIST involves intravenous (into the vein) infusions of octreotide, a medication that turns off the body's own production of insulin, as well as replacement of insulin at two different levels (low and high), with or without replacement of glucagon, and glucose (sugar). The study investigators will check blood sugar levels every few minutes during the procedure to determine the effect of the two different insulin levels. This study will evaluate the GIST in both healthy volunteers and those at higher risk for type 2 diabetes.

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols.

This study aims to examine the effects of a game-like program called cognitive control training (CT) for children with obsessive compulsive disorder (OCD). Children enrolled in this study will receive 4 weeks of the at-home computerized cognitive training program (AKL-T01) delivered on iPad (25 minutes/day, 5 days/week). Styled as a child-friendly video game, AKL-T01 CT taps focused attention, response inhibition, and working memory using a series of games to engage cognitive control processes. Children will complete the NIH Toolbox prior to, mid (2-weeks), and post-CT (4-weeks). Participants will complete MRI scans pre- and post-CT and then be offered a 12-week course of gold-standard Cognitive behavioral therapy with exposure and response prevention (or community referrals) after CT. The long-term goal of this study is to test how this CT intervention may enhance cognitive control capacity to reduce symptoms and improve response to cognitive behavioral therapy with exposure and response prevention in children with OCD.

The purpose of this study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases. The underlying hypothesis is that the pathologic morphological changes in the airway epithelium must be preceded by changes in the gene expression pattern of the airway epithelium and potentially in macrophages.

Eating disorders (EDs) are serious mental illness: someone dies of an ED every 52 minutes. EDs are highly related to a host of negative outcomes, including public health and individual disease burden, medical and psychological comorbidities, and social determinants of health (SDOH). Treatment response for EDs are suboptimal; there are no evidence-based treatment for adults with anorexia nervosa (AN) or Other Specified Feeding or Eating Disorder (OSFED) and only 50% of adults respond to current evidence based treatments. There are no precision treatments, nor any treatments that consider social context, in existence. Personalized treatments for EDs, that consider social contexts, are urgently needed to improve treatment response and minimize the suffering associated with these illnesses. The investigators' overall goal, extending upon their past work, is to create a treatment personalized based on idiographic (or one person) models (termed Transdiagnostic Network Informed Personalized Treatment for EDs; T-NIPT-ED). The investigators will carry out a two-phase study to systematically characterize individual mechanisms of treatment (Phase I: N=900) and then test the efficacy of each treatment module (Phase II: N=240 drawn from Phase I) compared to the current gold-standard treatment (Cognitive Behavioral Therapy Enhanced: CBT-E). The study goals are to (1) characterize the prevalence of T-NIPT-ED precision treatment mechanisms and medical and psychological comorbidities (e.g., obesity; depression), individual disease burden (e.g., disability), SDOH (e.g., food insecurity), and public health outcomes (e.g., service utilization) specific to these mechanisms, (2) identify if personalized target mechanisms improve when matched to evidence-based treatment modules of T-NIPT-ED and (3) test if change in T-NIPT-ED is associated with improved outcomes (vs CBT-E), including ED outcomes, comorbidities, disease burden, and public health outcomes and if these outcomes are moderated by SDOH. These goals will ultimately lead to the very first precision treatment for ED and can be extended to additional psychiatric illnesses. The proposed research uses highly innovative methods; intensive longitudinal data collected with mobile technology is combined with state-of-the art idiographic modeling methods to deliver a virtual, personalized treatment. This proposal integrates assessment of broad (e.g., SDOH; public health burden) and specific (e.g., ED symptoms) outcomes, to ensure that social context can be integrated into personalization. The proposed research has high clinical impact. Ultimately, this proposal will lead directly to the creation and dissemination of an evidence-based individually-personalized treatment for EDs, as well as will serve as an exemplar for precision treatment development across the entire field of psychiatry.

Hypertensive disorders of pregnancy (including preeclampsia) are among the leading causes of pregnancy complications and maternal deaths worldwide. They also increase the risks to the babies. Numerous interventions have been suggested in order to reduce the rate of preeclampsia. Low-dose aspirin is the most beneficial prophylactic approach in this regard. Nevertheless, aspirin failure is not uncommon. The genetic, laboratory, and clinical factors associated with low-dose aspirin failure in the prevention of preeclampsia are largely unknown. The presence of a genetic variant in PAR4 receptor expressed on platelets, is associated with increased platelet function and possibly with aspirin failure.
