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.

The purpose of this study is to see if it's possible to reach high cardiovascular intensity training parameters (exercise at a rate that elevates heart rate to the level recommended for improving strength and endurance) while walking in a wearable robotic exoskeleton. This study will also evaluate if exercising at high intensity will lead to improvement in walking ability. Participants in this study will be asked to attend 5 walking training sessions using Ekso exoskeleton. There will be two additional sessions, one before and one after the five training sessions. At these two sessions, study participants will be asked to participate in seated balance, walking speed and endurance tests and breathing assessments.

Inguinal hernias are a common surgical problem. Best management of occult inguinal hernias, defined as hernias unable to be felt on physical exam, is unknown. From prior studies we know that most inguinal hernias will eventually become symptomatic and require surgery (70%). However, doing a repair on a very small, occult hernia may open the patient up to surgical complications, like chronic pain, earlier than necessary. This will be a multi-center randomized controlled trial of surgical repair versus expectant management of occult inguinal hernias. Patients undergoing laparoscopic unilateral inguinal hernia repair will be included. At the time of surgery, the surgeon will determine if there is an occult hernia contralateral side. If present, patients will be randomized to repair of the occult side or expectant management of the occult side. After 1 year post-operative data has been assessed, a decision tool will be created and administered to patients to aid in their decision making about treatments for their hernia.
