This study is focused on males who have Hemophilia B and who need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also to control their bleeding events. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational, and part of a larger program to understand and treat Hemophilia B with a potential experimental new therapy in the future. There is no obligation to agree to taking part in this future study. The study is looking to answer several other research questions to help understand each participant's individual disease characteristics, including: - How often to use FIX replacement therapy, both on a regular basis (prophylaxis) and as needed to treat bleeding events - Measurement of FIX activity (factor IX is a clotting factor) by different laboratories using different types of tests in Hemophilia B participants - Possible complications from the FIX replacement therapy the patient receives (usual standard of care will continue to be used) - How quality of life is affected by Hemophilia B - How joint health is affected by Hemophilia B - How often the participant visits the emergency room, urgent care center, physician's office, hospital, or has a telemedicine visit as a result of bleeding events - Whether the body makes antibodies (a protein produced by the body's immune system) against the FIX replacement therapy you receive, which could make the drug less effective or could lead to side effects

Enroll-HD is a longitudinal, observational, multinational study that integrates two former Huntington's disease (HD) registries-REGISTRY in Europe, and COHORT in North America and Australasia-while also expanding to include sites in Latin America. More than 30,000 participants have now enrolled into the study. With annual assessments and no end date, Enroll-HD has built a large and rich database of longitudinal clinical data and biospecimens that form the basis for studies developing tools and biomarkers for progression and prognosis, identifying clinically-relevant phenotypic characteristics, and establishing clearly defined endpoints for interventional studies. Periodic cuts of the database are now available to any interested researcher to use in their research - visit www.enroll-hd.org/for-researchers/access-data/ to learn more.

Hysteroscopic surgery is widely used for the treatment of gynecological diseases, such as septum, synechiae, polyp and intrauterine fibroids. The complication rate is estimated as 0.22% and includes uterine perforation, massive bleeding, and fluid overload. Operative hysteroscopy intravascular absorption (OHIA) syndrome refers to fluid overload complications from operative hysteroscopies and is considered a major complication. Report describing the clinical association between irrigation fluid temperature to intravasation rate itself or the risk of fluid overload are limited mainly to theoretical models. Due to the aforementioned, we aim to evaluated the role of temperature on absorption of the irrigation solution in hysteroscopic surgery.
