The goal of the study is to generate a biorepository of longitudinal biofluids-blood (plasma and serum), cerebral spinal fluid (CSF) and urine linked to genetics and longitudinal clinical information that are made available to the research community. To accomplish these goals, we will enroll 800 Amyotrophic Lateral Sclerosis (ALS) patients and 200 healthy controls from sites globally, over a 5 year time frame. Additionally, speech and motor function and spirometry measures will be collected bi-weekly in a subset of participants. ALS participants will be asked to come to the clinic for 5 study visits approximately every 4 months. Healthy participants will be coming for 2 study visits with a 12-month interval between visits. These samples and clinical information will be stored in a de-identified manner and made available for investigators to use in future research studies.

The investigators will focus on three cohorts of brain tumor patients aged, 4-18 years, to answer two critical questions: 1) Can the investigators acquire high quality data relevant to cognitive function during the peri-diagnostic period and, 2) can the investigators develop predictive models for cognitive outcomes using serial examination of functional imaging and cognitive function. Any patient with a newly diagnosed brain tumor aged 4-18 will be eligible for enrollment in cohort 1. Only patients with previously diagnosed tumors of the posterior fossa will be eligible for cohort 2. For cohort 3, eligible patients will include patients with a clinical diagnosis of posterior fossa syndrome with physical impairments that prohibit completion of the NIH Toolbox Cognitive Battery. The investigators have decided to expand the eligible tumor types to better capture the most significant deficit variability that can be caused by tumors outside the posterior fossa. Thus, this focus will provide a platform to analyze the impact that different tumor types and different standard treatments have on cognitive dysfunction. The rationale for inclusion of subjects on cohort 3 is that posterior fossa syndrome is one of the most cognitively devastating diagnoses following a posterior fossa surgery. The causes of posterior fossa syndrome and unknown and there are currently no interventions to improve symptoms. RsfcMRI would offer a novel and non-invasive assessment of posterior fossa syndrome patients by assessing connectivity within and outside of the cerebellum. Expanding the tumor eligibility will allow us to further explore the effect tumor location will have on cognitive testing and rsfcMRI. Here, repeated evaluations on and off therapy will provide the necessary data points to establish trajectories of cognitive development and recovery in this population.

The investigators hypothesize that brief behavioral therapy and targeted propofol infusion in depressed geriatric patients will augment subsequent slow wave sleep and improve clinical and cognitive outcomes. The team will recruit 70 participants for a double-blinded placebo controlled randomized controlled trial. Two propofol infusions, 2-6 days apart, will be administered, targeting either a low propofol dose arm (minimal EEG slow waves, brain effect-site concentration 1-2 mcg/ml) or moderate dose propofol arm (maximal induction of EEG slow waves, brain effect site concentration of >2.5 mcg/ml). The pharmacologic intervention will be paired with 3-4 sessions of Brief Behavioral Therapy for Insomnia for all participants. To minimize bias, there will be no specific gender or ethnic background consideration for enrollment. This will be a single site investigation at Washington University Medical Center.

Plexiform neurofibromas (PN) are known to cause significant morbidity in children with NF1. The recent FDA approval for selumetinib in children 2 years and older with inoperable symptomatic PN was based on the finding that selumetinib shrinks the majority of PN in children with NF1 and results in clinically meaningful benefit such as improvement in pain or range of motion. However, many morbidities, such as blindness or nerve damage, cannot be fully reversed with PN shrinkage. Therefore, there remains a critical need in this patient population to determine if young participants with PN in high-risk locations may benefit from early medical intervention prior to the development of clinical problems. This study will determine whether participants with asymptomatic PN in high-risk locations can potentially benefit from early treatment with selumetinib.

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.

This is a three-part study evaluating the safety and efficacy of a PSMA-directed radioantibody (rosopatamab tetraxetan, conjugated to either In-111 or Ac-225). Part 1 will consist of one administration of In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants then will be enrolled into either Part 2 (Dose Optimization) or Part 3 (Dose Escalation and Expansion) depending on their prior treatment history. Participants qualifying for Part 2 will be randomized to receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle (dose administration on Day 1 and Day 15) at either 45 or 60 kBq/Kg. Participants qualifying for Part 3 must have received prior Lu-177-PSMA-radioligand therapy and will receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle at 45, 55, or 60 kBq/Kg. Dose limiting toxicities (DLTs) will be monitored in Part 3 to determine the recommended phase 2 dose (RP2D), and the study may enroll additional participants to be treated with the RP2D dose level. Participants enrolled into any part will attend study visits which will include blood samples, electrocardiogram (ECG), radiographic imaging, and physical examinations along with other assessments.

Aim 1. To determine the factors contributing to pain in patients with chronic pelvic pain with and without endometriosis Aim 2. To determine the changes following endometriosis lesion removal surgery in pain and sex hormone levels. Aim 3. To identify factors predicting clinical pain reduction after lesion removal surgery. Additional exploratory aims might compare subgroups of patients such as patients with vs. without endometriosis, with vs. without additional chronic pain syndromes, and with vs. without hormonal treatment. In addition, the role of lesion-specific immune signatures and psychological factors on pain will be explored. Patients with pelvic pain potentially due to endometriosis will complete questionnaires including social, health, behavioral, and psychological questionnaires. Patients will also complete a 2.5 hours study visit of psychophysical assessments of thermal and pressure stimuli. In addition, blood, urine, and saliva samples will be collected for hormonal, immune, and genetic analyses. Additional samples might be collected and stored for future analyses. For some participants, these procedures will be completed several times, including before the surgery as well as 3 months, 6 months and 1 year after surgery. After the surgery, surveys assessing pain and other symptoms will be sent every week on the first month and then monthly for 1 year. In addition, during the surgery, biopsies will be collected and analyzed to determine hormonal, immune and genetic factors. For adolescents, a parent/legal guardian will be asked to assist in completing some of the health-related surveys (i.e., physical developmental survey, health survey, migraine history survey).

With modern therapy, the survival rate for pediatric brain tumor patients has significantly improved, with over 70% of patients surviving their disease. However, this progress often comes at the cost of substantial morbidity, with cognitive deficits being the primary obstacle to independent living. Robust predictors of cognitive decline and a comprehensive understanding of the underlying mechanisms of cognitive injury remain elusive. This study will prospectively investigate alterations in brain resting state networks following radiation therapy using functional imaging. The hypothesis is that radiation therapy leads to dose-dependent alterations in functional connectivity in the networks associated with higher level cognition, ultimately leading to cognitive decline.

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.

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

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.
