In this study, people will first have a screening visit to make sure they can join and to check their pain and smoking habits. Next, they will have a training session to learn about the fake MRI scanner and how pain testing works. After that, they will have two brain scan sessions. For one scan, they will not smoke for 24 hours. For the other scan, they will smoke like normal. During each scan, they will feel heat pain and rate how it feels. Before and after each scan, they will answer questions about cravings, withdrawal, mood, and pain. There will be at least 2 days between the two scan sessions.
The purpose of this study is to learn how the places people go every day can make it easier or harder for them to quit smoking. The study uses technology to look for patterns in different environments and see how these places might affect a person’s cravings or habits. By doing this, the researchers hope to understand why quitting is harder for some people than others and find better ways to help people stop smoking in the future.
We are doing this study to test a device that tracks urine and stool output from people when they are in the hospital. This study is important because if the device works, it can improve patients' comfort while they are recovering from a stem cell transplant.
We are doing this study to find out how common it is for exocrine pancreatic insufficiency (EPI) to be present in children who have or are suspected to have celiac disease. We also want to compare different methods of testing for EPI in this study.
We are doing this study to measure quality of life and compare signs such as tiredness, feeling of unease, discomfort in the stomach, and pain in patients who have been treated with either PLA or HIGRT for liver cancer.
In this study visit, participants will have a regular eye exam. The doctor will place a small amount of special dye in the eye to look for any leaks. The doctor will use a light and microscope to look closely at the eye and may gently move the eyelid to see certain areas better. The visit should take about the same amount of time as a normal eye doctor appointment.
Children with IBS will eat a food called fructans to see if it makes their symptoms worse. If it does, they will be placed into one of three groups. One group will get a fake treatment called a placebo. The other two groups will get a fiber called psyllium in different amounts based on their age. They will take this for two weeks. During this time, they will check their poop and write down how they feel. The whole study may last up to three months.
We created this registry to have a database of healthy people who are interested in participating in research about lung health and breathing. We will use this registry to reach out to people and notify them about research studies in which they might be interested.
