The purpose of this research study is to better understand how blood flow and metabolism change can influence brain development in the early decades of life. We will examine brain blood flow and metabolism using magnetic resonance imaging (MRI). The brain's blood vessels expand and constrict to regulate blood flow based on the brain's needs. The amount of expanding and contracting the blood vessels can do varies by age. The brain's blood flow changes in small ways during everyday activities, such as normal brain growth, exercise, or deep concentration. Significant illness or psychological stress may increase the brain's metabolic demand or cause other bigger changes in blood flow. If blood vessels are not able to expand to give more blood flow when metabolic demand is high, the brain may not get all of the oxygen it needs. In extreme circumstances, if the brain is unable to get enough oxygen for a long time, a stroke may occur. Sometimes small strokes occur without other noticeable changes and are only detectable on an MRI. These are sometimes called "silent strokes." In less extreme circumstances, not having as much oxygen as it wants may cause the brain to grow and develop more slowly than it should. One way to test the ability of blood vessels to expand is by measuring blood flow while breathing in carbon dioxide. Carbon dioxide causes blood vessels in the brain to dilate without increasing brain metabolism. During this study participants may be asked to undergo a blood draw, MRI, and potential neuropsychological assessments. It is also possible that the study team will use a special mask to control the amount of carbon dioxide the participants breathe in so they don't breathe in too much.

The Autoimmune Liver disease Network for Kids (A-LiNK) is a multi-institutional group with the mission to deliver the best care to kids with pediatric autoimmune liver disease (AILD). This study will establish a shared clinical registry and a learning health network for the participating sites focusing on collecting and transmitting clinical measurement data, information about processes, and participation in an improvement collaborative. Pediatric Autoimmune Hepatitis (AIH) and Primary Sclerosing Cholangitis (PSC), represent a spectrum of AILD which present unique diagnostic and therapeutic challenges.A lack of accepted guidelines for disease monitoring or symptom management results in wide treatment variation with liver transplants indicated in refractory, progressive disease. The aims of A-LiNK are to: 1.) Create a learning health network focused on patient-centered outcomes research characterized by transparent sharing among centers, common priorities, and feasible plans for implementing new practices; 2) shift from traditional investigator-driven study to a patient and family-centered approach, and 3.) improve clinical outcomes and quality of life for pediatric AILD patients.

Patent Ductus Arteriosus is a developmental condition commonly observed among preterm infants. It is a condition where the opening between the two major blood vessels leading from the heart fail to close after birth. In the womb, the opening (ductus arteriosus) is the normal part of the circulatory system of the baby, but is expected to close at full term birth. If the opening is tiny, the condition can be self-limiting. If not, medications/surgery are options for treatment. There are two ways to treat patent ductus arteriosus - one is through closure of the opening with an FDA approved device called PICCOLO, the other is through supportive management (medications). No randomized controlled trials have been done previously to see if one of better than the other. Through our PIVOTAL study, the investigators aim to determine is one is indeed better than the other - if it is found that the percutaneous closure with PICCOLO is better, then it would immediately lead to a new standard of care. If not, then the investigators avoid an invasive costly procedure going forward.

The purpose of the study is to assess the impact of personalized music on emergence agitation (EA), as measured by Pediatric Anesthesia Emergence Delirium scores in pediatric patients recovering from elective procedures under general anesthesia. Personalized music may help to decrease EA in children undergoing elective surgeries under general anesthesia by decreasing perioperative anxiety and minimizing perceived pain. The study has the potential to improve perioperative care by improving safety, decreasing the need for postoperative pharmacologic and nursing interventions, thereby shortening the time of recovery and improving caregiver satisfaction. Participants participating in this study will be randomly assigned to receive personalized music plus standard of care, or standard of care alone. Those assigned to the music group will receive music in the preoperative holding area as well as in the post-operative care unit.

Lennox-Gastaut syndrome is a serious and rare form of epilepsy that begins in infancy and early childhood. Seizures and their consequences need medical attention, emergency encounters, and hospitalizations. Seizures disrupt home life for the patient and for family. Lennox-Gastaut syndrome is typically accompanied by disabilities in motor, communication, eating, and other skills needed for daily function. Lennox-Gastaut syndrome (LGS) has no cure. Although current treatments may help reduce the number of seizures, none are expected to eliminate them entirely; these treatments are palliative. The main treatments include anti-seizure medications and some surgical approaches, including the implantation of a vagus nerve stimulator (a pacemaker-like generator implanted in the chest wall and programmed by a physician to stimulate the vagus nerve in the neck) and corpus callosotomy (cutting through the band of fibers that connect the two sides of the brain). While both types of treatment (medications and surgeries) produce some benefit by reducing how often the seizures occur, both also have some risks. All medications can, in some patients, produce moderate to severe side effects. This is true of anti-seizure medications. Most patients with LGS take several anti-seizure medications at a time. Surgeries can also have associated risks and is additionally stressful for parents and family members. Currently, there is no strong evidence to support parents and physicians in deciding which type of treatment (more medicines or surgery) will be most successful for a child with LGS, and whether one or the other approach may lessen the toll that seizures take on a child's development and ability to function. This study has two components. It will engage a network of seven pediatric hospitals in the United States where children with Lennox-Gastaut syndrome are cared for and determine whether seizure-related emergency department visits and hospitalizations are more likely to be reduced following the use of additional medications or adding palliative surgery to existing medications. The investigators will determine whether medical versus surgical treatment is more likely to lessen some of the developmental and functional difficulties that affect patients with LGS. The study will also determine whether starting therapies at a younger versus older age makes a difference. The second component of the study will provide a description of the use of surgical versus medical treatment approaches across 18 pediatric hospitals in the United States (seven plus 11 centers). The investigators will describe how treatments differ across hospitals and over time. The results from this study will help parents and providers make more informed choices about treatment for children with Lennox-Gastaut syndrome and will highlight areas for improvement in providing the best possible health care for this severe, lifelong disorder.

This phase III trial compares the effect of adding sonrotoclax to zanubrutinib versus zanubrutinib alone for the treatment of patients with untreated chronic lymphoblastic leukemia (CLL)/small lymphocytic lymphoma (SLL). Sonrotoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Zanubrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell (a type of white blood cells) cancers such as mantel cell lymphoma at abnormal levels. This may help keep cancer cells from growing and spreading. Giving sonrotoclax and zanubrutinib may be more effective than zanubrutinib alone for the treatment of untreated CLL/SLL.

In this study, researchers will learn more about a drug called felzartamab in people who have received a kidney transplant and later developed a condition called microvascular inflammation (MVI). MVI is a type of injury to small blood vessels in the transplanted kidney and may be a sign of rejection by the body. It can lead to serious kidney problems over time. In many cases, MVI is caused by antibodies that attack the transplanted kidney. But in some people, MVI happens without these antibodies. This type of MVI is called isolated MVI. There are currently no approved treatments for isolated MVI. The main goal of the study is to learn about the effect felzartamab has on inflammation in the transplanted kidney. The main question researchers want to answer is: • How many participants have no signs of active inflammation in the transplanted kidney after 24 weeks of treatment with felzartamab? Researchers will also study how felzartamab affects kidney function, immune activity, and overall health. They will monitor safety through kidney biopsies, lab tests, and by recording adverse events throughout the study. Adverse events are health problems that may or may not be caused by the study drug. The study will be done in 2 parts as follows: - Participants will be randomly assigned to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. - In Part A, participants will receive their assigned drug for 24 weeks. Neither the researchers nor the participants will know who is receiving felzartamab or placebo. - Part B will last another 28 weeks. All participants will receive felzartamab and both participants and researchers will know this. - All treatments will be given by intravenous (IV) infusion at the study site. - Participants will have kidney biopsies at the start of the study, at Week 24, and at Week 52 to help measure changes in inflammation. - Participants will stay in the study for about 1 year.

Mild cognitive decline is common in early Parkinson disease (PD) and is associated with disability, reduced quality of life (QOL), and increased risk for dementia. Medical treatments for PD do not prevent or treat cognitive decline and may even exacerbate the problem. Unfortunately, existing cognitive interventions for PD, which focus on restoring deficient cognitive skills through cognitive training (repetitive practice of tasks that challenge specific cognitive skills), provide limited benefit for daily function and QOL. To overcome this limitation, the investigators use strategy training. the investigators help people develop targeted strategies to use in everyday life to circumvent cognitive deficits and accomplish daily activities. Contemporary cognitive rehabilitation evidence supports strategy training for other neurological conditions and mild cognitive impairment (MCI), but it has not been well-studied in PD. By teaching strategies for everyday cognition, the investigators hypothesize that our interventions will improve functional outcomes for people with PD. Study participants will complete a baseline cognitive testing session, 10 cognitive treatment sessions with a trained occupational therapist, then have follow-up visits with the study team at 1-week, 3-months, 6-months, and 12-months after completing the study intervention.

This phase II trial tests how well personalized reduction of chemotherapy (nivolumab, doxorubicin, vinblastine and dacarbazine) based on circulating tumor deoxyribonucleic acid (ctDNA) evaluation works for treating patients with Hodgkin lymphoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Chemotherapy drugs, such as nivolumab, doxorubicin, vinblastine and dacarbazine, 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. Many types of tumors tend to lose cells or release different types of cellular products including their DNA, which is referred to as ctDNA, into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids and, based on the result, assign patients to a reduced number of chemotherapy treatments or the standard number of chemotherapy treatments. Using ctDNA to assign a personalized reduction of chemotherapy may be effective in treating patients with advanced Hodgkin lymphoma.

This phase III trial compares the effect of adding tivozanib to standard therapy pembrolizumab versus pembrolizumab alone for the treatment of patients with high-risk renal cell carcinoma (RCC). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Tivozanib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving pembrolizumab and tivozanib together may work better than pembrolizumab alone in treating patients with RCC.
