The purpose of the study is to assess the effects of multiple doses of itraconazole (a strong CYP3A4 inhibitor) on single dose PK of casdatifan in healthy adults and to assess the effects of multiple doses of phenytoin (a strong CYP3A4 inducer) on single dose PK of casdatifan in healthy adults.

This study evaluates the impact of large language models (LLMs) versus traditional decision support tools on clinical decision-making in cardiology. General cardiologists will be randomized to manage real patient cases from a cardiovascular genetic cardiomyopathy clinic, with or without AI assistance. Each case will be assessed by two cardiologists, and their responses will be graded by blinded subspecialty experts using a standardized evaluation rubric. Read Less

Crews of future long-duration exploration missions will have to cope with a wide range of stressors that present significant challenges for maintaining optimal performance. Crews will have to operate under conditions of high workload, reduced sleep and circadian dysregulation, limited sensory stimulation, confinement and extended separation from family and friends, and communication delays isolating them from real-time interaction with ground support, which may be particularly critical in the event of emergencies. These factors present significant risks to optimal cognitive/behavioral functioning and performance, across individuals and teams, and such challenges will only increase in criticality as human exploration moves beyond Earth's orbit to targets such as the Moon and Mars. To help mitigate these risks, Massachusetts General Hospital, along with collaborators at the Massachusetts Institute of Technology, will investigate a novel, personalized and scalable, closed-loop platform technology for on-board behavioral health management-one which adapts the local working environment to optimize performance based on biosensor feedback.

The goal of this clinical trial is to learn whether a personalized brain stimulation method called repetitive transcranial magnetic stimulation (rTMS), combined with walking exercises, is a practical and tolerable approach to help people with Parkinson's disease who experience freezing of gait (FOG). FOG is a disabling symptom where people temporarily feel stuck and unable to start walking, even though they want to move. The main questions this study aims to answer are: Can people with Parkinson's disease and FOG tolerate this combined rTMS and walking training procedure? Can researchers successfully enroll and retain participants for this multi-visit intervention? Does the combination of rTMS and gait training show early signs of improving gait and reducing freezing episodes? This study does not include a comparison or placebo group. All participants will receive the same intervention. Participants will: Attend up to 15 study visits over about 16 weeks, with the option to combine visits to reduce burden. Complete brain imaging (MRI) before and after the intervention to guide and evaluate treatment. Receive a form of brain stimulation (rTMS) using a safe, non-invasive coil placed over a specific part of the brain called the supplementary motor area (SMA). The target is personalized using each person's MRI data. Participate in walking exercises that include cognitive tasks (dual-task gait training) after each set of brain stimulation sessions. Undergo assessments of walking ability, Parkinson's disease symptoms, and brain response to stimulation. Be videotaped during walking tasks to assess gait changes, while wearing small motion sensors on the body. Complete questionnaires about symptoms, safety, and tolerability. This study is being conducted at the Medical University of South Carolina (MUSC) and includes up to 15 adults between the ages of 50 and 80 who have been diagnosed with Parkinson's disease and experience FOG. Although rTMS is already FDA-cleared for depression and other conditions, it has not been approved for freezing of gait, and its use in this study is considered investigational. The stimulation device used has been determined to be non-significant risk (NSR) by the FDA. The study does not offer direct medical benefit to participants, but results from this trial may help researchers develop future treatments and better understand how brain stimulation affects walking difficulties in Parkinson's disease. Participation is voluntary, and individuals can withdraw from the study at any time without affecting their medical care Read Less

SGLT2 inhibitors have demonstrated to mitigate cardiorenal risk in people with type 2 diabetes and are likely to play an increasingly large role in the treatment of patients with diabetes, chronic kidney disease and hypertension. Yet the underlying mechanisms of its protective effects are incompletely understood and the salutary effect may be altered by dietary factors such as sodium intake. Therefore, carefully designed mechanistic trials are needed to better understand the interplay between ertugliflozin and salt intake and to potentially modify salt intake to maximize treatment response. In addition, the study could contribute to hypotheses concerning the effects of SGLT2 inhibitors in combination with other drugs that affect sodium homeostasis and could help to explain the differences in kidney outcomes observed in (outcome) trials, which include different ethnicities with potential differences in dietary habits.

Primary Objective: This is a study to investigate the feasibility of harvesting, expanding, and selecting T lymphocytes from cancer patients and healthy volunteers. The preliminary objective of this study is aimed at selecting PD-1+ and CTLA4+ T cells and other cellular fractions from peripheral blood of cancer patients and healthy volunteers by using specific conjugated antibodies, evaluating their functional ex vivo anti-tumor cytotoxicity against targeted autologous tumor cells.

The purpose of this study is to examine whether weight reduction decreases intramyocellular (IMCL) and hepatic lipid content, and improves insulin sensitivity of muscle and fat tissue in people who are insulin resistant and have a family history of type 2 diabetes. Hepatic mitochondrial oxidation will be assesses using a 3 hour triple tracer study (D7 glucose, 3-13C lactate and 13C4 beta-hydroxybutyrate). Read Less

Objectives: Our specific aims are to: Aim 1: Examine the feasibility of a couple-based meditation program in 50 patients with metastatic lung cancer and their partners. Aim 2: Establish the initial efficacy of a couple-based meditation program in patients and their partners regarding physical, psychological, and spiritual quality of life outcomes. Read Less

This phase II trial studies the side effects and best dose of radiation therapy and to see how well it works in treating patients with cancer that has spread to other places in the body (metastatic) or has increased in size after being treated with immunotherapy. Giving radiation therapy may help to control the cancer after the disease has gotten worse after receiving immunotherapy in patients with cancer that has spread to the other places in the body.

The goal of this study is to find markers that may help to predict why some patients who have monoclonal gammopathy of unknown significance (MGUS) or smoldering multiple myeloma (SMM) that have no signs or symptoms of disease (asymptomatic) develop multiple myeloma, while others do not. Studying markers such as age, level of proteins in blood, percent of abnormal blood cells in the bone marrow, genes in the abnormal blood cells, and bone abnormalities may help researchers to validate clinical and genomic predictors for future use in clinical practice.
