Subjects in the first group will be enrolled in the GM-CSF for Reversal of Immunoparalysis in Pediatric Sepsis-induced MODS (GRACE-2) trial, comparing GM-CSF versus placebo. Subjects in the second group will be an observational cohort with no intervention, because this group has very low mortality and morbidity. Subjects in the third group will be enrolled in the Targeted Reversal of Inflammation in Pediatric Sepsis-induced MODS (TRIPS) trial, comparing anakinra and placebo. The fourth group, with very severe inflammation,
will be an observational cohort because clinical management of the inflammation
is standard of care, and there is no equipoise about enrolling these children in a placebo controlled trial. The primary outcome of both trials will be duration and severity of organ dysfunction using the cumulative PELOD-2 score, and secondary outcomes will assess health related quality of life and family functioning at 3 and 12 months.

This research study is being done to determine whether it is safe to give a kidney transplant from a donor with hepatitis C to a patient without hepatitis C. This study is looking for participants in need of a kidney transplant who are willing to accept a kidney from a patient with hepatitis C.

This study is for subjects that have been diagnosed with advanced cancer. The purpose of this study is to find subjects with advanced cancer that had an exceptional disease response (improvement) while being treated with standard immunotherapy agents. This study will monitor their progression through a series of blood draws. Subjects will either continue immunotherapy or have completed immunotherapy. Participation in the study will take about 6 visits over a period of about 2 years. During this time the study team will follow your care by clinic visit, phone contact and/or medical record review every three months to collect information on the status of your cancer. This is not a treatment study.

In this research study, healthy participants will receive ear stimulation during brain imaging. Ear stimulation will involve the study team applying small electrodes to the outer part of your left ear and administering small amounts of electrical stimulation that may cause you to feel a "tickling" sensation on your ear. Participants will receive four, 8-min ear stimulation sessions in the scanner, and the order of the sessions is randomly assigned to you.

Knowledge gained from this study will help us better understand how stimulation of nerves in your ear turns on different parts of the brain.

Approximately 50% of people who have had a stroke report feelings of tiredness and/or a lack of energy that is not reduced with rest and sleep. This phenomenon is known as post-stroke fatigue. Post-stroke fatigue negatively affects an individual's quality of life and participation in rehabilitation, social, and physical activities. There are currently no known effective treatment options for people with post-stroke fatigue. This study will investigate the use of a non-invasive brain stimulation technique called transcranial magnetic stimulation (TMS) to treat post-stroke fatigue. This method has proven useful in other conditions such as depression and we will measure the effects of TMS on reducing fatigue in individuals more than six months post-stroke.

This study is for patients that have been diagnosed with locally advanced head and neck squamous cell carcinoma. The purpose of this research study is to evaluate the effectiveness of using a combination of pembrolizumab and olaparib when given before and after standard chemoradiation therapy in treating locally advanced head and neck squamous cell carcinoma. Pembrolizumab and olaparib are drugs that are approved for treatment of different cancers including lung, head and neck, breast and prostate cancer. However, FDA has not approved use of these two drugs together in treating head and neck cancer.

Treatment will be offered in three phases. In the induction phase, participants will receive a single infusion of pembrolizumab and will take olaparib tablets twice daily for total of 21 days. Participants will move to the chemoradiation phase, where they will receive radiation therapy and chemotherapy per routine standard care, for a total of 7 weeks. Chemoradiation therapy is done on a daily basis (excluding weekends), and chemotherapy therapy will involve a cisplatin infusion once weekly. At the conclusion of this phase, participants start the maintenance phase, which involves treatment with pembrolizumab and olaparib in cycles that are 42-days long. Treatment will include a single pembrolizumab infusion during each cycle and taking olaparib tablets twice daily during each cycle. Total number of cycles to be completed in the maintenance phase are 8 cycles. Participants can expect to be in this study for about 6.5 years.

This study is for men and women with HER2-positive salivary gland cancer (SGC) that has come back, spread outside of their salivary gland, or cannot be removed by surgery. This study is being done to find out if ado-trastuzumab emtansine (T-DM1) extends the length of time without the cancer getting worse compared to the usual approach.

The GORE RELIEF Clinical study is evaluating if anti-clotting medications and/ or closure of Patent foramen ovale (PFO) using the GORE® CARDIOFORM Septal Occluder device in the heart will reduce migraine headaches in adults. The purpose of the study is to investigate whether patients who take a certain type of medication and have a decrease in migraine headaches will also have a decrease in migraine headaches after closure of the PFO, without having to take the medication long-term. It will also look at how safe the study device is (safety) in closing the PFO. The study is randomized and blinded; subjects will have an equal chance of being assigned study medication or placebo pills.

The purpose of this study is to evaluate magrolimab in combination with pembrolizumab only, with pembrolizumab + platinum + 5-FU chemotherapy, and with zimberelimab + platinum + 5-FU chemotherapy in patients with untreated metastatic head and neck cancer. Magrolimab will also be evaluated in combination with docetaxel in patients with metastatic head and neck cancer who have received prior treatment.

This study is split into two phases, the initial phase (safety run-in) is to confirm a safe dose of magrolimab in combination with pembrolizumab + platinum + 5-FU chemotherapy and with docetaxel. The second phase will evaluate the effectiveness of magrolimab in combination with pembrolizumab only (without chemotherapy), with pembrolizumab + platinum + 5-FU chemotherapy, with zimberelimab + platinum + 5-FU, and with docetaxel.

Other purposes of this study include determining the quantity of magrolimab in the blood, your quality of life and the side effects these drugs have on the body.

This study is enrolling subjects with advanced solid tumors with the TP53 Y220C alteration in cancer cells. This alteration is a mutation of the tumor that can be found through laboratory tests that use a sample of tissue, blood, or other fluids to check for signs of cancer. This study involves research testing the safety, best dose, side effects and timing of the study drug called PC1486. You will take the study drug, PC14586, in the form of a tablet. If assigned to the combination treatment arm (Part 1), you will also be given pembrolizumab as an intravenous (IV) infusion. Pembrolizumab is a type of immunotherapy that is FDA approved to treat your kind of cancer. The study drug PC1486 is not approved by the Food and Drug Administration (FDA). This study drug targets the TP53 Y220C genetic alteration in tumor cells. During the pre-screening portion, participants will provide either archived tissue or a fresh tumor sample to test for the genetic alteration. If the participants show the genetic tumor alteration in the cancer cells, they may be asked to participate in the trial. Treatment arms are groups or subgroups of participants in a clinical trial. This study will have two arms: one studies PC1486 alone and the second arm studies PC1486 in combination with Pembrolizumab against advanced solid tumors. PC14586 is a small molecule (chemical) that is designed to act on the genetic alteration TP53 Y220C in cancer cells to slow the growth of cancer, and it is taken orally. This study involves blood tests, a possible tumor biopsy, CT, and MRI scans. The study will last approximately 6 months of treatment, followed up by a check-up after the first 3 weeks and every 3 months after. Some common risks (observed in greater than 20% of people) include: Nausea, Vomiting, Abnormal liver tests, Abnormal kidney test (possible kidney damage
