The investigators propose to use the novel SV2a-PET ligand, [F-18]SDM-8 to assess synaptic density in progressive multiple sclerosis (PMS) (including primary progressive multiple sclerosis (PPMS) and secondary progressive multiple sclerosis (SPMS)), given its improved imaging characteristics and potential for large scale applicability. The specific aims of the study are: Aim 1: To compare the cortical and subcortical grey matter synaptic density in PMS patients, patients with relapsing-remitting MS (RRMS), and healthy subjects, using a novel [F-18] labeled synaptic density PET ligand, [F-18]SDM8, also known as [F-18]SynvesT-1. Aim 2: To compare the relationship of synaptic density PET and standard 3T MRI measures including global and regional brain atrophy and lesion load with clinical measures of physical disability, cognitive impairment, fatigue and depression in MS patients. Aim 3: To assess the relationship of synaptic density PET with serum neurofilament light chain (NfL) and with serum measurements of inflammatory markers, IL-1β, TNF-α, IL-6, MCP-1 (Monocyte Chemoattractant Protein-1) and MIF-1 (Macrophage Migration Inhibitory Factor-1).

The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery. All patients with a qualifying POAF event, who decline randomization, will be offered the option of enrollment in a parallel registry that captures their baseline risk profile and their treatment strategy in terms of anticoagulants or antiplatelets received. These patients will also be asked to fill out a brief decliner survey.

The specific aims of the study are: Primary: To determine the presence and regional distribution of microglial activation, as assessed by Fluorine-18 (18F) labeled "Peripheral Benzodiazepine Receptor 06" (PBR06) -PET, in subjects with active Relapsing Remitting Multiple Sclerosis (RRMS), Secondary Progressive Multiple Sclerosis (SPMS), and Alzheimer's Disease (AD) as compared to healthy controls Secondary: 1. To assess the relationship between microglial activation and clinical variables including disease severity and comorbidities (such as pain, fatigue and/or depression), as well as clinical MRI findings (such as lesions and atrophy) 2. A pilot substudy aims to establish the non-inferiority of [F-18]PBR06 as compared with Carbon-11 [C-11] labeled "Peripheral Benzodiazepine Receptor 28" (PBR28) PET in patients with RRMS. Hypothesis: The working hypothesis is that there is microglial activation in multiple sclerosis and Alzheimer's disease as compared to healthy controls and that the pattern/ regional distribution of microglial activation is different in Multiple Sclerosis (MS) versus AD and correlates with disease severity and comorbidities. In addition, the investigators hypothesize that [F-18]PBR06-PET scans will be at least as good as [C-11]PBR28-PET scans, the current gold standard.

In previous studies, Proton Beam Radiation Therapy (PBRT) has been found to show better results in treating patients with cancer, both because there is better control of where in the body the radiation is directed and because it is associated with less severe long term side effects. However, there is limited published data demonstrating these results. The goal of the Proton and Photon Consortium Registry (PPCR) is to enroll children treated with radiation in order to describe the population that currently receives radiation and better compare the short-term and long-term benefits of different types of radiotherapy. The data collected from this study will help facilitate research on radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data that many centers that deliver radiation therapy already collect in routine operations.

Cerebral/Cortical Visual Impairment (CVI) is the leading cause of childhood visual impairment in the United States and other industrialized countries. CVI is a brain-based visual disorder in which visual acuity or visual fields are reduced despite a normal eye examination or greater-than-expected visual impairment relative to ocular pathology. CVI is increasingly recognized in children with neurological conditions, yet it often remains undiagnosed until later childhood, delaying opportunities for early intervention. Population-based studies suggest that CVI is more common than previously understood. Recent estimates indicate that over 180,000 individuals in the United States aged 0-22 years may have diagnosed or likely CVI, with only a minority formally identified. Children with CVI frequently have co-occurring neurological conditions, including cerebral palsy, epilepsy, developmental delays, or genetic disorders. Infants born preterm or with conditions such as hypoxic-ischemic encephalopathy (HIE), perinatal stroke, or white matter injury are at particularly high risk. Prospective research also shows that a substantial proportion of infants born very preterm exhibit behavioral features of CVI later in childhood. Despite improvements in neonatal neurocritical care, early detection of CVI remains challenging. Current clinical practice focuses on managing conditions such as HIE, perinatal stroke, periventricular leukomalacia, and other brain injuries, but there is limited research evaluating structured early identification pathways for CVI in infancy. Diagnostic tools such as brain MRI and Visual Evoked Potentials (VEP) have shown potential for identifying brain-based visual dysfunction, but their integration into early predictive models for CVI has not been fully explored. This study addresses a critical gap in pediatric care by prospectively evaluating high-risk neonates using clinical, neuroimaging, neurophysiologic, and standardized developmental assessments through 24 months of age. Early identification of CVI may support timely referral for visual rehabilitation and developmental services, potentially improving long-term functional outcomes. Developing a predictive model for early CVI detection will contribute to improved clinical pathways, enhance early diagnosis, and reduce the long-term educational and social burden associated with undetected CVI. Ultimately, this research aims to improve outcomes and quality of life for infants at risk for brain-based visual impairment.

During breast surgery, sensory nerves are cut which may lead to reduced sensation and pain. Surgical reinnervation techniques have been developed with the aim of improving postoperative sensation by preserving the nerves and connecting them to the nipple and areola. The investigators aim to compare postoperative sensation and patient reported outcomes in patients undergoing reinnervation versus those not undergoing reinnervation to determine if there is a difference. The investigators will investigate this in patients undergoing gender-affirming mastectomy, implant-based breast reconstruction and autologous breast reconstruction. The investigators will use various tools that measure sensation quantitatively.
