Diffusion MRI of the Abdomen
The purpose of this research is to see if a new magnetic resonance imaging (MRI) method will be able to improve the images taken of the abdomen. This new method includes some changes to help avoid movements that may disrupt the images like breathing, heartbeats and other involuntary motion that …
A Study of Spinraza (Nusinersen) Exposure in Pregnant Women With Spinal Muscular Atrophy (SMA) Within Existing SMA Registries
The primary objectives of the study are to prospectively evaluate pregnancy complications and outcomes in participants with SMA, birth outcomes and adverse effects in infants born to participants with SMA, who were exposed to nusinersen up to 14 months prior to the first day of their last menstrual period (LMP) …
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 …
Using Microbial Genomics to Elucidate the Source of Central-line Associated Bloodstream Infections
Central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infection in children and are associated with morbidity and mortality. This study will attempt to identify the source of bloodstream infections (BSIs) in children with CLABSI because we hypothesize that many of the BSIs that are currently classified as CLABSIs …
Phenotyping Asthma for Bronchial Thermoplasty
This study will evaluate a new imaging technology, called optical coherence tomography (OCT) to examine the asthmatic airways before and after bronchial thermoplasty, which is a new treatment option for severe asthmatic patients. The aim of this study is to learn more about how airways respond to this new treatment. …
De-escalated Radiation for Human Papillomavirus-Positive Squamous Cell Carcinoma of the Oropharynx
This is a single-arm, observational registry study determining the effects of reduced radiation dose in select patients with human papillomavirus (HPV) positive oropharyngeal cancer.
International Multisite Transcatheter Tricuspid Valve Therapies Registry
For a long time, tricuspid valve disease has been considered as less important than left-sided valvular heart disease. If treated in an advanced stage and simultaneously with other cardiac diseases, it is associated with significant morbidity and mortality. Hence, physicians tend to refer patients more aggressively to surgery (1). Transcatheter …
Validation of Interleukins and Other Cytokines Together With OCT Imaging for Rapid Infectious Keratitis Assessment
As conventional corneal scraping with bacterial culturing has several disadvantages such as long duration until diagnosis, invasiveness and lacks alternatives, there is demand for a novel non-invasive, rapid test in keratitis management. First aim of this study will be to evaluate the influence of TNF-alpha on Gram+ and Gram- bacteria …
Retinal Imaging in Patients With Inherited Retinal Degenerations
The purpose of this study is to determine whether the structure and function of the human retina can be studied with high resolution in patients with inherited retinal degenerations using the Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO).
LE as a Marker for Periprosthetic Joint Infection
Testing and comparison of a novel point-of-care electrochemical assay to detect and help diagnose periprosthetic joint infection on the hip and knee to the standard of care test
