This observational study will evaluate the efficacy and safety of RoActemra/Actemra (tocilizumab) in clinical practice in patients with moderate to severe rheumatoid arthritis. Data will be collected from patients for the 12 months following the first infusion of RoActemra/Actemr…

The central objective of this study will be to evaluate the relationship between estrogen levels and the pain following oocyte retrieval in women undergoing in vitro fertilization.

Abdominal Compartment Syndrome (ASC) is defined by an Intra Abdominal Hypertension (IAH) associated with a new organ failure. The occurrence of this syndrome is not well known in infants. Preterm birth is frequently associated with gastrointestinal complications, particularly Nec…

Background: \- Little is known about how the brain changes during childhood and adolescence, how genes affect this process, or how the brains of people with 7q11.23 genetic variation change during this period. Researchers are interested in using magnetic resonance imaging to stu…

The goal of this observational study is to learn about fertility preservation for pre-pubertal, peri-pubertal, and adult participants that are unable to pursue clinical standard of care fertility preservation such as egg (oocyte) and embryo cryopreservation. In addition, this st…

Thumb carpometacarpal (CMC-1) osteoarthritis is a common condition causing pain and disability, particularly among middle-aged and older women. When non-operative treatment fails, surgery is indicated. In Sweden, trapeziectomy (TE), with or without tendon-based adjuncts, is the s…

The incidence of vertebrobasilar dissecting aneurysms (VBDAs) is about 1/100,000\~1.5/100,000, and it is one of the most important causes of stroke in young and middle-aged people. In recent years, with the development of medical imaging technology, the detection rate of this dis…

This study aims to 1) implement a culturally and contextually rooted innovative multifoci, social marketing intervention involving societal focused media campaign elements to break down the barriers and facilitate timely and appropriate screening practices for cervical cancer; 2)…

We are conducting an eight week longitudinal study to learn if blood levels of certain naturally occurring compounds and genetic markers differ between patients with depression and healthy adults who are not depressed, and if any such differences relate to memory performance, moo…

Background: Lyme disease is an infection caused by Borrelia burgdorferi, a bacteria that is transmitted to humans by ticks. It can cause many different symptoms including rash, fever, headache, meningitis (infection of the central nervous system), and arthritis. While most patie…

Investigators at Boston Children's Hospital are conducting research in order to better understand the genetic factors which may contribute to epilepsy and related disorders. These findings may help explain the broad spectrum of clinical characteristics and outcomes seen in people…

The purpose of this study is to test a memory training program for breast cancer survivors who have problems with memory after receiving chemotherapy. Since breast cancer survivors have been reported to have trouble with their memory, a program to help these problems is important…

This repository will establish for the first time a system to carefully assess and monitor over time the general health and the amount of cholesterol in the arteries of U.S. children and adults with homozygous familial hypercholesterolemia (hoFH). Patients with this very rare dis…

The purpose of this study is to learn more about how being treated for breast cancer affects patients' employment, financial situation, and quality of life on a short-term basis and on a long term basis. Most studies of employment after breast cancer have focused on Caucasian wom…

Lymph node involvement remains the main criteria for postoperative chemotherapy in patients with colon cancer (CC) without distant metastasis. To date, the prognostic value of the somatic quantitative molecular alterations such as loss or gain of genomic region is not established…

This study is one of the three projects of an NIH Rare Disease Clinical Research Consortium. A "consortium" is a group of centres sharing information and resources to perform research. The consortium research focuses on brain blood vessel malformations in three different rare dis…

The mechanisms of oxidative stress and inflammation involved in mood disorders are factors of chronicity and severity. These mechanisms induce a phenomenon of accelerated cellular senescence and are reflected by alterations in systemic gene expression detectable in leukocytes in …

This study will evaluate a method to detect tumor cells that are circulating in the blood without getting a biopsy. The investigators already know from other studies that cancer tumors shed a small number of cells into the bloodstream every day. These are called circulating tumor…
