The study will compare the effectiveness of endoscopic surveillance and endoscopic eradication therapy (EET) for the management of Barrett's esophagus (BE) and low-grade dysplasia (LGD).

This project is an extension of the CDC-funded FORWARD (Fragile X Online Registry With Accessible Research Database) study. From its inception in 2010, the goal of the FORWARD study has been to characterize the natural history of fragile X syndrome (FXS). This current extension project is known as FORWARD-MARCH (Multiple Assessments for Research CHaracterization) because it will include multiple assessments to characterize behavioral, adaptive, and cognitive function in greater depth and thereby further improve understanding of the natural history of FXS. FORWARD-MARCH continues the mission of FORWARD to better understand the natural history of FXS in order to improve the lives of children and adolescents with FXS and the lives of their families. FORWARD-MARCH will also better define trajectories of development in FXS that will be useful in understanding the long-term effects of an intervention relative to the natural history of FXS.

FORWARD-MARCH builds upon the foundation of the FORWARD study. The FORWARD study included 24 participating FXS specialty clinics throughout the US that are members of the FXCRC (Fragile X Clinical & Research Consortium). The FORWARD study worked closely with the Centers for Disease Control and Prevention (CDC), the National Fragile X Foundation (NFXF), and other stakeholders in the FXS community. FORWARD-MARCH will also involve a contractor, Chickasaw Nation Industries (CNI), funded through a contract with the CDC. CNI will assist in data collection and management.

Between September 2022 and August 2026, FORWARD-MARCH expects to enroll at least 600 individuals with fragile X syndrome who were born between 2003-2017. The majority of these individuals will already be FORWARD study participants, enabling researchers to conduct longitudinal analyses incorporating previously collected data. Cognitive, behavioral, and adaptive function will be assessed using parent or caregiver-completed surveys and in-person clinical assessments. After completion of data collection, deidentified data will be securely maintained at CDC and will be an important long-term resource for analyses of the natural history of FXS.

Previous phases of the FORWARD study, conducted between 2012 and 2022, have received IRB review and approval by the institutions of each participating clinic. These previous phases of the study did not require review by a CDC IRB, as CDC had no participant contact and did not have access to personal identifying information (PII). The extension of the FORWARD study covered in this protocol (FORWARD-MARCH, 2022-2026) will continue to be reviewed and approved by the institutions of each participating clinic conducting data collection. However, review and approval are also being sought from the CDC IRB because PII will be maintained on CDC servers and because CDC's contractor, CNI, will regularly have access to PII and interact directly with study participants. A reliance agreement allowing CNI to rely on CDC's IRB is being developed and will be executed before data collection is begun. To clarify which aspects of the protocol involve CDC and CNI staff (rather than just clinic staff), sections 3,4 and 5 of this protocol document each end with a subsection that specifically focuses on the role of CDC and CNI staff.

This study is for anyone 18 years or older who provides unpaid care for a loved one living with cancer outside of the hospital setting. The purpose of this study is to help future caregivers and patients by learning how mental fatigue affects caregivers of persons living with cancer and determine if mental fatigue, participating in self-care activities, and general caregiver quality of life are related. Informal caregivers will be invited to complete a confidential, online survey that takes between 25 and 35 minutes to finish. Caregivers who complete the survey may be contacted and asked to participate in a 45-60 minute follow up interview either online or via phone if they are interested. The results of this study will help guide future research to identify ways healthcare professionals can help caregivers handle the stresses of caregiving and provide the best care possible to their loved ones at home.

This is a prospective, observational research study for patients with IBD under the care of a gastroenterologist provider. The objective of the Corrona Inflammatory Bowel Diseases (IBD) Registry is to create a national cohort of patients with IBD.The diseases under study include Crohn's Disease (CD), Ulcerative Colitis (UC) and Indeterminate Colitis (IC). Data collected will be used to better characterize the natural history of the disease and to extensively evaluate the effectiveness and safety of medications approved for the treatment of IBD .Approximately 10,000 patients and 150 clinical sites in North America will be recruited to participate with no defined upper limit for either target. The Corrona IBD Registry is a long-term observational study; therefore, the duration of the registry has no pre-determined stop date.

The purpose of the study is to 1) determine the most practical study recruitment strategies for pregnant and postpartum women with marijuana use and 2) collect data to determine what types of studies pregnant and postpartum women are willing to take part in. Participation involves completing an online survey that takes about 10 minutes to complete.

The purpose of this study is to create a de-identified, public use,
repository of data of Chronic Obstructive Pulmonary Disease (COPD)
patients with by Alpha-1 antitrypsin deficiency (AATD), a rare genetic
condition that can cause COPD and emphysema.

This study will optimize the DeepView SnapShot Portable device by imaging patients' burn wounds. These images contribute to the machine learning technology that will one day be used to aid burn clinicians in their treatment plans. Patients will be approached by the burn study team at the hospital when they initially come in for a burn wound treatment. Duration of the study for patients is 21 days.

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation method often used to assess connectivity between the brain and specific muscles. This research study is aimed at finding the changes in the manner brain communicates with leg muscles post-stroke and its effects on movement coordination during walking.

Smell loss has been reported in more than 50% of older adults. Currently there are no validated methods for classifying patients with smell loss in aging based on either disease site or process. This study aims to better understand how age affects the sense of smell. This study will involve those 50 and older and will take up to 2 years, with 2 follow up annual visits.
