Analysis of Lumbar Spine Stenosis Specimens for Identification of Transthyretin Cardiac Amyloidosis
Primary objective: To identify older adults with transthyretin cardiac amyloidosis (ATTR-CA) early in the course of the illness, at a time when disease modifying therapies are most effective. The specific aims of this epidemiologic investigation include: 1. To identify subjects with previous lumbar spinal stenosis (LSS) Surgery who have evidence of transthyretin (TTR) amyloid deposits in spinal specimens and could be at risk for ATTR cardiac amyloidosis. 2. To evaluate for ATTR-CA among those with localized TTR in the spinal tissue. The study will also explore the following: 1. The prevalence of amyloid in lumbar spinal stenosis specimens by Congo Red...

Analysis of Prognostic Cell Signaling Factors in Adolescent Idiopathic Scoliosis
The purpose of this study is to identify potential markers for curve progression in adolescent idiopathic scoliosis (AIS). Despite its prevalence and impact on child health, the etiology of AIS and molecular mechanisms underlying its development and progression remain poorly understood. Clinical criteria and features cannot adequately predict which children, diagnosed with mild disease, will undergo subsequent curve progression requiring intervention. The investigators hypothesize that alterations in specific genetic markers will be correlated with the progression of AIS curves over time. Thus, these markers could be used in the future to develop a reliable, inexpensive and...

Analysis of T and B Cell Repertoire Changes in Response to Orencia® (abatacept) in Rheumatoid Arthritis
The condition that will be studied is Rheumatoid Arthritis (RA), and in particular, RA patients with moderate to highly active disease who were prescribed Abatacept (Orencia®) (ABA) by their physician during their setting of care at Hospital for Special Surgery (HSS). This investigator-initiated, prospective, comparative, 3-arm observational study will examine changes in lymphocytes in RA patients starting abatacept compared to RA patients starting TNF inhibitors and to healthy controls. This will help investigators to learn more about the processes that cause joints to swell and hurt. This may also offer clues that might predict which patients will have a good or poor response to...

A Natural History Study Seeks to Understand the Clinical, Genomic, Pharmacological, Laboratory, and Dietary Determinates of Pyrimidine and Purine Metabolism Disorders
Background: Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that can be fatal. DPPMs are not well understood, and researchers want to learn more about what causes them and how to treat them. Objective: To learn more about factors that affect DPPMs by comparing test results from affected, uaffected family members, and healthy people. Eligibility: Three types of participants are needed:...

Anchoring Sequential Intermittent Long Acting Antimicrobials With Medication for Opioid Use Disorder (MOUD) for Invasive Infections Related to Opioid Use
Standard of care for patients with opioid use disorder and complicated infections is discharge to subacute nursing facilities on IV antibiotics until completion of treatment course. We aim to determine the efficacy of an alternative strategy using intermittent outpatient oritavancin therapy dosed weekly combined with initiation and continuation of medication assisted treatment for opioid use disorder for completion of antimicrobial therapy in a 12 week prospective, open-label study. Patients hospitalized for a drug use related infection and thought to need prolonged parenteral antimicrobial therapy will be assessed by a substance use consultant and Infectious Diseases service. If...

An Immediate Functional Progression Program for Adolescent Athletes With Spondylolysis
Spondylolysis, a stress fracture in the pars interarticularis of a lumbar vertebra, is the most common identifiable cause of low back pain (LBP) in adolescent athletes, occurring in 14-30% of athletes who experience LBP. Spondylolysis can cause significant pain and disability and months of exclusion from sports or an active lifestyle. Standard care of spondylolysis in adolescent athletes is primarily based on expert opinion, with dramatic variations in clinical practice, including restrictive bracing, extended rest periods before the intervention, long durations out of sport and activity, and suboptimal long-term clinical outcomes. As the next step towards our research goal, the...

An Open-label Study of Povetacicept in Autoantibody-Associated Glomerular Diseases
The goal of this clinical study is to evaluate multiple dose levels of povetacicept in adults with immunoglobulin A (IgA) nephropathy, membranous nephropathy, lupus-related kidney disease (lupus nephritis). or anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis to determine if povetacicept is safe and potentially beneficial in treating these diseases. During the study treatment period, participants will receive povetacicept approximately every 4 weeks for 6 months, with the possibility of participating in a 6-month treatment extension period and an optional 52 week treatment extension period .

Anterior Cervical Disectomy and Fusion Using the Tritanium® C Anterior Cervical Cage for One or Two-Levels
This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of Cervical Spine 2 to Thoracic 1 (C2-T1) and diagnosed with degenerative disc disease will be screened for the study.
