This randomized phase III trial studies short course vaginal cuff brachytherapy to see how well it works compared with standard of care vaginal cuff brachytherapy in treating participants with stage I-II endometrial cancer. Short course vaginal cuff brachytherapy, also known as internal radiation therapy, uses (over a shorter period) radioactive material placed directly into or near a tumor in the upper portion of the vagina to kill tumor cells. After completion of cohort 1 (108 participants), the protocol was expended to add a second cohort of 80 additional participants, and re-opened study recruitment. Read Less

The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-120 in advanced hematologic malignancies that harbor an IDH1 mutation. The first portion of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of AG-120 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second portion of the study is a dose expansion phase where four cohorts of patients will receive AG-120 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose. Additionally, the study includes a substudy evaluating the safety and tolerability, clinical activity, pharmacokinetics, and pharmacodynamics of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome with an IDH1 mutation. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs. Read Less

Pregnancy is associated with a increased risk of developing blood clots. There is nearly a 5 times greater risk of developing a blood clot in pregnancy. Lovenox is a medication that helps to prevent the body from developing clots. It is safe to use in pregnancy. Previous studies have demonstrated that despite recommendation of Lovenox, to prevent blood clots, the majority of patient's (70 to 90%) did not receive adequate levels of Lovenox at times throughout the day, which likely increases the risk of developing clots. The increase in blood volume and increase in kidney function that occurs in pregnancy may contribute to the inadequate levels. Currently the recommendation for pregnant and nonpregnant patients requiring Lovenox, is to calculate the daily dose of Lovenox and split the dose, giving half in the morning and the other half in the evening. This research study proposes that due to changes in the body during pregnancy that the daily Lovenox dosing be split into three times a day to achieve more consistent levels of Lovenox than twice a day in pregnant women.

Premature babies often need help immediately after birth to open their lungs to air, start breathing and keep their hearts beating. Opening their lungs can be difficult, and once open the under-developed lungs of premature babies will often collapse again between each breath. To prevent this nearly all premature babies receive some form of mechanical respiratory support to aid breathing. Common to all types of respiratory support is the delivery of a treatment called positive end-expiratory pressure, or PEEP. PEEP gives air, or a mixture of air and oxygen, to the lung between each breath to keep the lungs open and stop them collapsing. Currently, clinicians do not have enough evidence on the right amount, or level, of PEEP to give at birth. As a result, doctors around the world give different amounts (or levels) of PEEP to premature babies at birth. In this study, the Investigators will look at 2 different approaches to PEEP to help premature babies during their first breaths at birth. At the moment, the Investigators do not know if one is better than the other. One is to give the same PEEP level to the lungs. The others is to give a high PEEP level at birth when the lungs are hardest to open and then decrease the PEEP later once the lungs are opened and the baby is breathing. Very premature babies have a risk of long-term lung disease (chronic lung disease). The more breathing support a premature baby needs, the more likely the risk of developing chronic lung disease. The Investigators want to find out whether one method of opening the baby's lungs at birth results in them needing less breathing support. This research has been initiated by a group of doctors from Australia, the Netherlands and the USA, all who look after premature babies. Read Less

Medical scientists want to find better ways to treat neuroblastoma and to find ways to prevent the tumor from growing back. To do this, they need more information about the characteristics of neuroblastoma cells. Therefore, they want to study samples of neuroblastoma tissues and neuroblastoma and normal cells in the blood and bone marrow that may be related to the growth of neuroblastoma cells. Doctors and other medical scientists also want to find better ways to detect and measure neuroblastoma to improve the ability to follow the response of tumor cells to therapy. Read Less

The present study seeks to examine the implementation process of culturally tailoring screening and brief intervention for both chronic pain and opioid misuse/opioid use disorder in three American Indian and Alaska Native (AI/AN) serving clinics. The investigators also will assess staff perspectives on this implementation as well as a survey to understand clients at these sites who have chronic pain and opioid misuse/opioid use disorder.

The goal of this prospective, multi-center, randomized, controlled study is to compare the safety and efficacy of the ProtEmbo Cerebral Embolic Protection device to a hybrid control (no embolic protection device ('No Device') and the Sentinel device) in subjects with severe symptomatic native aortic valve stenosis indicated undergoing a TAVR procedure.

The main purpose of this study is to gain a better understanding of the distinct mental states and physical reactions that can arise during a psychedelic experience. By repeatedly assessing the same participants in an MRI while under the effects of psilocybin, the investigators want to identify reliable brain and body reactions arising during these psychedelic experiences. It is hoped that this will provide an insight to inspire future research on psilocybin and related psychedelics as well as inform on their therapeutic action. This study will involve up to 12 healthy volunteers with previous psychedelic experience. Participants in this study will be given four doses of psilocybin, with breaks of at least seven days in between dosing visits. The first dosing visit will feature a 10 mg dose of psilocybin, which can be considerate a low to moderate dose, whereas the remaining three dosing visits will feature 25 mg psilocybin, a high dose that is consistent with the dosage chosen for several modern clinical trials with psilocybin. From the initial in-person screening visit to the final follow-up, participants will be in this study for approximately 6-12 weeks and visit the research site 5 times. The first visit will be an in-person screening visit, during which the investigators will assess participants' eligibility to be enrolled. There will be 4 subsequent visits to the scan center for dosing and magnetic resonance imaging (MRI) scanning, and there will be a final remote follow up. Each of the four dosing visits will include four periods of lying within the MRI scanner for scanning, each of these 'in-scanner' sessions will last for \~ 45 minutes. Actual scans, which are also called 'runs' last for \~ 12 mins. During these 'runs', the investigators will ask participants two brief questions about how positive or negative their current experience is every 100 seconds. They will be able to record their answers using a button box which they will be operating with their hand. One day after each dosing visit, the investigators will schedule a phone call with the participant to check how they are doing and perform an informal interview focused on their experience while under the effects of psilocybin.

The goal of this study is to investigate whether Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting a part of the brain involved in memory will have an affect on brain activity and whether it may improve memory in people with Mild Cognitive Impairment and Mild Alzheimer's Disease. The main questions the study seeks to answer are: 1. Can LIFUP increase brain activity in the targeted area? 2. Can LIFUP improve memory in people with MCI and mild AD? 3. Can LIFUP improve connectivity of memory networks in the brain? Participants in this study will complete MRIs and memory testing, and receive Low Intensity Focused Ultrasound to a part of their brain involved in memory (the entorhinal cortex). Read Less
