REtroperitoneal SArcoma Registry: an International Prospective Initiative
Surgery is currently the only potentially curative treatment modality for localized retroperitoneal sarcoma (RPS). Available studies regarding oncologic outcomes are mainly retrospective in nature, and RPS are recognized as a rare disease. Therefore, prospective analysis of high quality data is a top priority. Primary Objectives of this study are: to …
Natural History Study of and Genetic Modifiers in Spinocerebellar Ataxias
Spinocerebellar ataxias (SCA) are genetic neurological diseases that cause imbalance, poor coordination, and speech difficulties. There are different kinds of SCA and this study will focus on types 1, 2,3, and 6 (SCA 1, SCA 2, SCA 3 , also known as Machado-Joseph disease and SCA 6). The diseases are …
Immune Monitoring and Assay Development in Organ Transplant Recipients
The purpose of this study to develop a well-characterized library of blood, biopsy tissue, and urine samples from transplant patients. Subjects without transplants will also be enrolled for comparison. Samples will be used to study the characteristics of patients undergoing transplantation that influence their response to transplant therapies and their …
Liver Transplantation in Patients With CirrHosis and Severe Acute-on-Chronic Liver Failure: iNdications and outComEs
Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as …
Feminizing Hormone Therapy and the Rectal Mucosa Immune Environment in Transgender Women
The overarching goal of this research study is to achieve a better understanding of the rectal mucosal effects of feminizing hormones in people assigned male sex at birth and currently taking feminizing hormones who have sex with men. Better understanding the rectal mucosa in this population will allow for the …
Atypical Hemolytic-Uremic Syndrome (aHUS) Registry
Post-marketing safety data on patients treated and untreated with eculizumab or ravulizumab.
Real-world Experience of Catheter Ablation for the Treatment of Paroxysmal and Persistent Atrial Fibrillation
The primary purpose of this registry is to obtain real-world clinical experience of Paroxysmal (PAF) and Persistent (PsAF) Atrial Fibrillation ablation radiofrequency (RF) technologies. Data from the registry will be used to assess clinical outcomes, including procedural efficiency, safety, and long-term, effectiveness of catheter ablation with novel RF technologies in …
