The proportion of noncardiac surgeries performed as same-day surgery is increasing worldwide, with more complex surgeries being performed on higher risk patients in the outpatient setting. Little is known on the risk factors, incidence and prognosis of patients undergoing same-day noncardiac surgery. The main objective of this study is to inform on the incidence and risk factors of cardiovascular and other adverse events after same-day surgery and to develop risk prediction tools to better inform on the risk and selection of patients undergoing same-day surgery.

The Generic Database (GDB) is a registry of very low birth weight infants born alive in NICHD Neonatal Research Network (NRN) centers. The GDB collects observational baseline data on both mothers and infants, and the therapies used and outcomes of the infants. The information collected is not specific to a disease or treatment (i.e., it is "generic"). Data are analyzed to find associations and trends between baseline information, treatments, and infant outcome, and to develop future NRN trials.

The Phase 3 portion of Study RAD-GRIN-101 is a multinational, multicenter, randomized, double-blind, placebo-controlled trial followed by an open-label extension to evaluate the efficacy and safety of radiprodil in participants with GRIN-related neurodevelopmental disorder (GRIN-NDD) with a gain-of-function (GoF) genetic variant. This study will enroll two cohorts: one cohort of participants with a minimal number of countable motor seizures (with or without behavioral symptoms) (Phase 3 Cohort 1: Qualifying Seizures Cohort); and a second cohort with disease symptoms but no seizures or fewer seizures than required for the Qualifying Seizures Cohort (Phase 3 Cohort 2: Without Qualifying Seizures Auxiliary Cohort). Participants in each cohort will be randomized 1:1 to receive active drug (radiprodil) or matching placebo (Part A). Following completion of Part A, all eligible participants (including those previously on placebo) may continue into the open-label extension period (Part B) to receive radiprodil. The placebo-controlled portion is expected to be approximately 16 weeks for participants in Phase 3 Cohort 1 and 28 weeks for participants in Phase 3 Cohort 2. The study will evaluate the effect of radiprodil on seizures and non-seizure symptoms and assess safety.

Alzheimer's disease (AD) is characterized by the accumulation of tau pathology, and blood-based biomarkers such as phosphorylated tau-217 (pTau217) have been identified as sensitive and specific predictors of AD risk. Recent studies suggest that individuals with elevated pTau217 levels may be at increased risk for developing AD and cognitive dysfunction. This observational study will examine donated human plasma samples to determine whether some units of donated blood contain abnormally elevated pTau217 concentrations. The overarching goal is to evaluate whether transfusion of blood with higher pTau217 may pose risks to recipients and whether such units should be avoided in clinical use.

The investigators propose a single-center, randomized, controlled trial to determine whether early initiation of proton pump inhibitor (PPI), pantoprazole, will decrease acute kidney injury (AKI) for trauma patients presenting with hemorrhagic shock compared to routine timing of initiation of PPI. Kidney injury will be assessed by the urinary kidney injury biomarkers, and the incidence, severity and AKI-free days within first week and major adverse kidney events (MAKE) at day 30. The specific aims of the study will be achieved by a cohort of 100 patients to receive either early(study) or routine (control) administration of pantoprazole for 2 days after the initial injury insult.

Posttraumatic stress disorder in adolescence impairs neurobiological networks underlying cognitive, social and emotional skills. Neuroimaging research that seeks to identify the neural mechanisms of treatments for PTSD could lead to novel treatments, but progress has been slow using current methods. The proposed study uses an innovative approach to identify neural mechanisms of specific phases of trauma-focused therapy for youth with PTSD, allowing a new understanding of brain changes associated with the process of therapy.

Although automatic follow-up is a nearly universal practice, research has shown that these visits are often unnecessary after hospitalizations caused by bronchiolitis. Despite endorsement by national pediatric authorities, robust evidence, and family enthusiasm for as-needed (PRN) follow-up, it remains substantially underutilized for children hospitalized for bronchiolitis. The goal of I-DECIDE is to compare the effects of two multi-component implementation strategies, both of which aim to (a) increase PRN follow-up prescribing by hospitalists (physicians who care for hospitalized children) and (b) decrease unnecessary follow-up visit attendance by families.
