The goal of this observational study is to evaluate the long-term safety and wound healing durability (up to 15 years) for participants with Recessive Dystrophic Epidermolysis Bullosa (RDEB) who were treated with pz-cel. The main questions it aims to answer are: - The long-term safety profile of pz-cel. - The wound healing durability of pz-cel. - The occurrence of all malignancies after treatment with pz-cel, regardless of type or location, in individuals who received pz-cel treatment for RDEB in the post-marketing setting. Participants will then be followed annually up to 15 years post-treatment. Assessments will occur via remote data collection. If the participants provider determines an office visit is necessary after the first year, some of this data can be collected in person as well. Annual assessments will include, but are not limited to: - Review of Adverse Events (AEs), Serious Adverse Events (SAEs), hospitalizations, and any evidence of malignancies and potential retroviral infection - Wound-healing durability data collection via the modified Caregiver Global Impression of Change for Wound Healing - Any changes in concomitant medications and procedures.

The goal of this clinical trial is to determine if perfusion index (PI) can reliably predict changes in systolic blood pressure (SBP) in persons with spinal cord injury (SCI) during a cool temperature challenge. Participants with SCI can be 18-75 years of age, male or female, neurological level of injury C4-T12, ASIA Impairment Scale (AIS: A or B: motor complete) or gender and healthy age-matched able-bodied (AB) controls. The main question this study aims to answer is: can PI reliably predict change in SBP during a cool temperature challenge? We hypothesize that PI can be used as a biomarker of SBP in persons with SCI. Researchers will compare the relationship of 1) changes in PI and SBP and 2) relationship of changes in other vital signs to SBP, during the cool temperature challenge. The researchers aim to determine if PI can be used as a biomarker of SBP in persons with SCI during a cool temperature challenge (experimental group/arm). Able-bodied controls (control group/arm) will receive the same intervention (cool challenge) as the experimental group. During the study, participants will be asked to wear only shorts and a T-shirt so that their skin can be exposed to the warm and cool temperatures of the 2 rooms. We will put put on non-invasive sensors (taped or attached on the surface of your body) to measure PI, BP, and other vital signs. We will record these measurements while you are seated in a wheelchair for 10 minutes in a warm room and up to 90 minutes in a cool room.

The goal of this observational study is to learn if there are potential digital and plasma-based biomarkers that could help detect, predict, and prognosticate delirium in older adult patients who are admitted to the intensive care unit (ICU). The main question DELTA aims to answer is: Can digital biometrics predict and detect delirium in older adult ICU patients? Do biomarkers of neurodegeneration fluctuate in ICU patients in such a way that delrium could potentially be predicted? Participants admitted o the ICU will wear a digital device to collect biometric data and will have serial plasma samples collected during ICU admission and patients will be also assessed for delirium daily by study staff.

In this experiment, subjects will view shapes on a screen with varying colors and be asked to focus their eyes on the shapes. The shapes will look as though they are jumping to random distances away from the eye. As the subjects focus their eyes on the shapes, the investigators will measure the focus of their eyes using a device called a wavefront sensor. This device uses infrared light to measure the optical properties of the eye in real time. Our goal is to find out how well the eye focuses on different colors. Our broad goal is to better understand how the eye focuses because that process is a major part of having clear and good vision.

This is an interventional study that will test whether a breathing exercise called Inspiratory Muscle Strength Training (IMST) can safely and effectively lower blood pressure during late pregnancy. The goal is to see if a home-based breathing training can help prevent or reduce high blood pressure disorders in pregnancy. The main objectives are to make sure the training is safe and tolerable for pregnant women and to examine blood pressure and blood vessel health. Participants in their third trimester will be randomly assigned to either do moderate resistance IMST or a minimal resistance sham IMST, for 5 to 8 minutes a day over six weeks.

Background: Trisomy 8 mosaicism is a genetic disorder that can increase inflammation in the body. Symptoms include fevers; sores or ulcers in the mouth, digestive tract, or genital area; skin rashes; problems in organs or tissues; and changes in bone marrow cells. Researchers want to conduct a natural history study to learn more about these symptoms and what causes them. Objective: To gather data and samples from people with and without the trisomy 8 mosaicism. Eligibility: People of any age with the trisomy 8 gene mosaicism. Their healthy relatives are also needed. Design: Affected participants will have visits every 1 to 2 years for 30 years at NIH. Each visit will take 1 to 5 days and may be in-person or remote. With remote visits, participants may have a video call with the study team and samples may be sent to researchers by mail. Participants may have these procedures: Physical exam, with blood tests. Tests of brain function and motor skills. Sensory tests. Researchers will see how participants respond to sensations such as pinpricks, heat, cold, and pressure. Magnetic resonance imaging (MRI) scan of the brain and/or spine. X-ray of the spine. Ultrasound test of heart function (echocardiogram). Tissues samples (biopsies) collected from the skin, inside of the mouth, and bone marrow. Swabs to collect cells from the mouth, skin, and vagina. Collection of blood, stool, urine, saliva, hair, and fingernail samples. X-rays, MRI, and heart tests will be done only once. Other procedures may be repeated at each visit. All tests and procedures are voluntary. Healthy relatives who enroll will have a baseline visit and then follow-up visits as needed. They will have a physical exam. The inside of their mouth may be swabbed. Samples of blood, stool, urine, and saliva may be taken.

The purpose of this project is to determine the feasibility and preliminary efficacy of a mental health skill-building and empowerment program (MH-POWER) for college students on the autism spectrum facing stress, anxiety, and depression. The program, grounded in cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and habit formation, will be implemented through weekly sessions and daily practice over 8 weeks. To evaluate the program's preliminary efficacy, we will measure mental health symptoms at baseline, mid-point, post-intervention, and one-month follow-up. Positive outcomes could lead to scalable interventions.

This study looks at the safety and performance of the CLiKX device. The device is used to place ear tubes (also called ventilation tubes) in children and adults. These tubes help treat chronic ear fluid (otitis media with effusion) and other conditions where a doctor decides an ear tube is needed. In this study, surgeons will use the CLiKX device to place an ear tube in the patient's ear. The study will check if the surgeon can place the tube correctly in the right position. The procedure will first be attempted with no anesthesia or with local anesthesia. If needed, the surgeon may then use mild sedation or general anesthesia. The study will also look at how well patients tolerate the procedure by checking for side affects during the procedure. Finally, the study will look at how the device affects the procedure and patient safety. Researchers will review how the procedure is performed and will follow patients for up to 30 days after the procedure to continue to check for any side effects..
