Carotid Aneurysm Registry
To prospectively collect data on ECAA we designed the Carotid Aneurysm Registry (CAR). The aim of this study is to collect data on ECAA and its treatment to assess the natural history of ECAA and the success and safety of different treatment strategies.
Physiologic Measure of VIPN
The purpose of this study is the development of a physiologic endpoint using a novel technology that would provide an objective, easy to use and more sensitive assessment of VIPN in children and adolescents. The ability to more easily detect and monitor VIPN, even before it is clinically evident, would …
Restoration of Thumb Strength and Function in Basal Joint Arthritis: A Comparative Effectiveness Trial (RESTART)
The purpose of this study is to evaluate the basis for three widely held fundamental tenets about surgical intervention for thumb basal joint arthritis; Trapeziectomy with ligament reconstruction and metacarpal stabilization is associated with superior functional outcomes and strength, Preservation of the arthroplasty space correlates with functional outcomes, pain relief, …
Attentional Biases, Reward Sensitivity, and Cognitive Control in Adults With Bipolar Disorder
The purpose of this study is to use eye-tracking technology to study attentional biases, reward sensitivity, and cognitive control in adult patients with bipolar disorder with or without anxiety and/or substance use disorder comorbidity.
Correlation Between the Changes of Retinal Structure and Function and Ischemic Stroke
Ischemic stroke is the most common type of stroke, accounting for 60%-80% of all types of strokes, and is one of the leading global causes of death and severe disability. In the risk factors of stroke, carotid atherosclerosis have higher incidence.As the only visible microvessels in vivo, retinal can provides …
Neuroradiology Assesses Chiari Malformation's Impact on Airways, Cranial Base, and Sleep Disorders in Children.
The severity of sleep disorders in patients with Chiari malformations can vary. The investigators propose to establish a correlation between the severity of sleep-disordered breathing (SDB) and the quantitative neuroradiological data of the airways, cranial base foramina, and posterior cranial fossae
Imaging Genetics of Laryngeal Dystonia
The contribution of genetic risk factors to the development of focal dystonias is evident. However, understanding of how variations in the causative gene expression lead to variations in brain abnormalities in different phenotypes of dystonia (e.g., familial, sporadic) remains limited. The research program of the investigators is set to determine …
Prostate Oligometastatic Cancer Management Driven by Disease Biology et/or Immunoactivity (PROMETEO)
Currently, despite the advent of next-generation imaging has improved the detection of Oligometastatic prostate cancer (OMPC), prognostic biomarkers able to stratify patients and monitor treatment response are lacking and urgently needed. Mounting evidence suggests that molecular profiling of the disease and host immune activity evaluation can reveal OMPC heterogeneity and …
High-resolution Phosphocreatine and Creatine Mapping of Human Muscle and Brain
In this study, we aim to develop and validate a noninvasive approach for quantifying and imaging energy metabolism, without contrast agents, on widely available clinical MRI scanners. Briefly, this technique allows specific and selective imaging of the energy metabolite phosphocreatine (PCr), in vivo and non-invasively. PCr is one of the …
Use of Cysteamine in the Treatment of Cystinosis
Cystinosis is an inherited disease resulting in poor growth and kidney failure. There is no known cure for cystinosis, although kidney transplantation may help the renal failure and prolong survival. Both the kidney damage and growth failure are thought to be due to the accumulation of the amino acid cystine …
