Substudy B: This study was designed to evaluate the safety and immunogenicity of a second dose of RSVpreF when administered after a dosing interval of approximately 1 year: * At a dose of 120µg (as studied in the Phase 3 Efficacy Study) * Blood samples will be collected for antibody testing. * The duration of the study for each participant will be up to approximately 18 months. * The study will be conducted in Argentina. Substudy C: This study was designed to evaluate the safety and immunogenicity of a second dose of RSVpreF when administered after a dosing interval of either 3 or 4 years: * At a dose of 120µg (as studied in the Phase 3 Efficacy Study) * Participants will receive either placebo or a second dose of RSVpreF approximately 3 or 4 years after receiving the initial dose of RSVpreF in the main efficacy study. * Blood samples will be collected for antibody testing. * The duration of the study for each participant will be up to approximately 18 months. * The study will be conducted in the United States and Canada.

In a recent study, researchers let patients choose what medications to go home with after endocrine surgery. This has not been done in outpatient breast surgery, though several institutions have moved towards avoiding opioids altogether after breast surgery. These institutions only prescribed rescue opioids upon request. The aim of this study is to compare a similar "opt-in" protocol for narcotics to usual care (where patients are routinely discharged with opioids) for outpatient breast surgery. This study will be designed as a randomized, controlled trial. When adult patients consent for outpatient breast surgery, the patients will be asked to participate in the study. Patients who are currently using narcotics would be excluded. The investigators would then randomize participants to the "opt-in" protocol versus being provided with a standard opioid prescription after surgery. Patients in the opt-in protocol will be recommended a pain treatment regimen with over-the-counter medications, acetaminophen or ibuprofen. These patients will be reassured that if their pain is uncontrolled after discharge, a narcotic prescription will be called in to their pharmacy if requested. The investigators will assess patient pain scores and medication use in the recovery area using the electronic medical record. The investigators will collect data on patient pain scores and medication use after discharge on a daily basis via phone call or electronically transmitted survey. The investigators will also evaluate patients at the time of their follow-up visits. Any patient phone calls will be routed to study personnel who will fill narcotic prescription requests if requested. Finally, among patients who do receive an opioid prescription, the investigators will track their opioid consumption. Read Less

Several strategies or contexts help patients with Parkinson's disease to move more quickly or normally, however the brain mechanisms underlying these phenomena are poorly understood. The proposed studies use intraoperative recordings during DBS surgery for Parkinson's disease to understand the brain mechanisms supporting improved movements elicited by external cues. The central hypothesis is that distinct networks are involved in movement improvement depending on characteristics of the facilitating stimulus. Participants will perform movement tasks during awake surgery performed exclusively for clinical indications. The identified biomarkers may provide targets for future neuromodulation therapies to improve symptoms that are refractory to current treatments, such as freezing of gait. Read Less

The primary aim is to test whether abatacept, as compared to placebo, is associated with a reduction in major adverse cardiac events (MACE) among participants hospitalized with myocarditis secondary to an immune checkpoint inhibitor (ICI). The primary outcome, MACE, is a composite of first occurrence of cardiovascular death, non-fatal sudden cardiac arrest, cardiogenic shock, significant ventricular arrythmias, significant bradyarrythmias, or incident heart failure.

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research. Read Less

This study will seek to enroll immunocompromised patients with Lower Tract parainfluenza infection. It also contains a sub-study to enroll patients with severe COVID-19. Read Less

The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future. Read Less

This is a multicenter, double-blind, randomized study to evaluate the efficacy and safety of a daily single oral dose of tasimelteon and matching placebo in male and female participants with DSWPD. Read Less

This is a multiple site, randomized, double blinded parallel-group controlled study. The purpose of this study is to evaluate efficacy, safety, and tolerability of repeated, daily sessions with the STARSTIM device, which delivers transcranial cathodal direct current stimulation (tDCS). Subjects will be treated with STARTSTIM or sham device for 10 sessions over a 2-week period. The subjects will be followed for an additional 10 weeks post treatment. Quality of Life questionnaires and adverse events will be collected and evaluated. Read Less

The purpose of this clinical study is to compare how well two different devices for achieving hemostasis perform in patients undergoing transfemoral procedures with 6 French Access. Both devices are approved by the FDA for this use, and have already been used by clinicians on patients undergoing transfemoral procedures. It is believed that the use of both devices in combination compared to the Perclose alone will shorten the time that it takes to 'seal' the artery, resulting in a shorter period of time that patients would need to lay flat.

The goal of this observational study is to determine whether a marker of dead space (the end-tidal to alveolar dead space fraction \[AVDSf\]) is more strongly associated with mortality risk than markers of oxygenation abnormality (oxygenation index) and to determine whether dead space (AVDSf) is an important marker of heterogeneity in the inhaled nitric oxide (iNO) treatment effect for children with acute respiratory distress syndrome (ARDS). The study aims are: 1. To validate AVDSf for risk stratification of mortality in pediatric ARDS 2. To determine if there is heterogeneity in treatment effect for iNO defined by AVDSf 3. To detect the association between AVDSf and microvascular dysfunction trajectory and whether iNO therapy modifies this association This is a prospective, multicenter observational study of 1260 mechanically ventilated children with moderate to severe ARDS. In a subgroup of 450 children with severe ARDS, longitudinal blood samples will be obtained to measure plasma protein markers. Read Less
