  • Levetiracetam in the Treatment of Neonatal Seizures

    open to eligible people ages up to 1 month

    The main purpose of this study is to determine the maximum safe tolerated dose of LEV in the treatment of neonatal seizures. Our hypothesis is that optimal dosing of Levetiracetam (LEV) to treat neonatal seizures is significantly greater than 60mg/kg. This study will be an open label dose-escalation, preliminary safety and efficacy study. There will be a randomized control treatment component. Infants recognized as having neonatal seizures or as being at risk of developing seizures will be recruited and started on continuous video EEG monitoring (CEEG). Eligibility will be confirmed and consent will be obtained. In the first 2 phases of the study, neurologists will identify neonates with mild-moderate seizure burden (less than 8 minutes cumulative seizure activity per hour), appropriate for study with LEV, and exclude patients with higher seizure burden where treatment with PHB is more appropriate. Phase 3 of the dose escalation will only proceed if additional efficacy of LEV has been demonstrated in phases 1 and 2. In Phase 3 we will recruit neonates with seizures of greater severity up to 30 minute seizure burden/hour. This will make the final results of study more generalizable. If seizures are confirmed, enrolled subjects will receive 60mg/kg of LEV. Subjects whose seizures persist or recur 15 minutes after the first infusion is complete, subjects will then be randomized in the dose escalation study. Patients in the dose escalation study will be randomly assigned to receive either higher dose LEV or treatment with the control drug PHB in a 3:1 allocation ratio, stratified by site.

  • buRst-supprESsion TO Stop Refractory Status Epilepticus Post-cardiac Arrest

    open to eligible people ages 18 years and up

    RESTORE is a randomized clinical trial investigating the safety and feasibility of using EEG treatment targets (burst suppression vs. seizure suppression) for post-cardiac arrest refractory status epilepticus treatment.

  • Effects of Hypoxic Breathwork

    open to eligible people ages 18-45

    This project will study changes that occur during a short period of intensive daily slow-paced breathing and breath hold practice (i.e., "breathwork"). On the first and last days of the week-long practice, investigators will conduct high-density EEG recordings during breathwork to evaluate spectral power, coherence, and causality dynamics of the brain when it is naïve to breathwork and after adaptation to a breathwork practice. Breath, blood, urine, saliva, stool samples, biometric data, and sleep EEG will be collected before the start of daily breathwork practice and again after 1 week of breathwork practice to examine the effect of breathwork on full body biochemistry, molecular biology, and sleep. Investigators will also use questionnaires to assess the impact of breathwork on stress and sleep quality.

  • Influence of Cooling Duration on Efficacy in Cardiac Arrest Patients

    open to eligible people ages 18 years and up

    A multicenter, randomized, adaptive allocation clinical trial to determine if increasing durations of induced hypothermia are associated with an increasing rate of good neurological outcomes and to identify the optimal duration of induced hypothermia for neuroprotection in comatose survivors of cardiac arrest.

  • Pediatric Influence of Cooling Duration on Efficacy in Cardiac Arrest Patients (P-ICECAP)

    open to eligible people ages up to 17 years

    This is a multicenter trial to establish the efficacy of cooling and the optimal duration of induced hypothermia for neuroprotection in pediatric comatose survivors of cardiac arrest. The study team hypothesizes that longer durations of cooling may improve either the proportion of children that attain a good neurobehavioral recovery or may result in better recovery among the proportion already categorized as having a good outcome.

  • Accuracy of the EvieMED Ring Pulse Oximeter in Profound Hypoxia

    open to eligible people ages 18-49

    The goal of this study was to evaluate the accuracy of pulse oximeters over the range of 70-100% per the International Organization for Standardization (ISO) 80601-2-61:2019. Four test devices were placed on each subject on the left or right hand with two at the finger base and two at the fingertip. Motion equipment was used to control motion of the test devices. In addition, two test devices were placed on the contralateral hand on the base of a finger and also on the fingertip. Finally, a test wrist device was placed on either the left or right wrist. SpO2 measurements from these devices were compared to sampling of arterial blood during brief stable oxygen desaturation in healthy volunteers to evaluate the claimed range.

  • Neonatal Seizure Registry, GEnetics of Post-Neonatal Epilepsy

    open to all eligible people

    The NSR-GENE study is a longitudinal cohort study of approximately 300 parent-child trios from the Neonatal Seizure Registry and participating site outpatient clinics that aims to evaluate whether and how genes alter the risk of post-neonatal epilepsy among children with acute provoked neonatal seizures. The researchers aim to develop prediction rules to stratify neonates into low, medium, and high risk for post-neonatal epilepsy based on clinical, electroencephalogram (EEG), magnetic resonance imaging (MRI), and genetic risk factors.

  • Pulse Oximeter Accuracy in Healthy Humans During Hypoxia

    open to eligible people ages 21-50

    The aim of this project is to test the accuracy of pulse oximeters during mild, moderate and severe hypoxia. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxygen. This study will be done on healthy male or females between the age group of 18-50.

  • NKT2152, a HIF2α Inhibitor, in Patients with Advanced Clear Cell Renal Cell Carcinoma

    Sorry, in progress, not accepting new patients

    The goal of the Phase 1 portion is to identify the maximum tolerated dose (MTD) and/or the recommended doses for expansion (RDEs) of NKT2152. The Phase 2 portion will evaluate the efficacy of NKT2152 in ccRCC.

  • Delayed Cord Clamping With Oxygen In Extremely Low Gestation Infants

    Sorry, in progress, not accepting new patients

    This study is being conducted to compare the incidence of preterm infants (up to 28+6 weeks GA) who achieve a peripheral oxygen saturation of 80 percent by 5 minutes of life (MOL) given mask CPAP/PPV with an FiO2 of 1.0 during DCC for 90 seconds (HI Group) to infants given mask CPAP/PPV with an FiO2 of .30 during DCC for 90 seconds (LO Group).

  • Fetal Cerebrovascular Autoregulation in Congenital Heart Disease and Association With Neonatal Neurobehavior

    Sorry, not currently recruiting here

    Determine 1) the impact of abnormal fetal cerebrovascular physiology with neurodevelopmental delay (ND) outcomes and 2) how this relationship is modified by patient and environmental factors such as chronic congenital heart disease (CCHD) lesion, maternal-fetal environment, and social determinants of heath (SDOH) in a diverse population using a multicenter design. Pregnant women will be approached during one of their fetal cardiology clinic visits.

  • Determination of SpO2 and PR Accuracy Specifications At Rest (71Ag_Vital-0031)

    Sorry, in progress, not accepting new patients

    The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients at rest

  • Tissue-specific Insulin Resistance in Obstructive Sleep Apnea: Role of Hypoxia

    Sorry, in progress, not accepting new patients

    Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.
