Arthritis, Juvenile

The purpose of this study is to evaluate long-term safety of subcutaneous guselkumab in pediatric participants with moderately to severely active ulcerative colitis, or moderately to severely active Crohn's disease, or juvenile psoriatic arthritis (jPsA).

Families of children with arthritis are highly interested in the benefits of diet to improve their child's disease and future health outcomes. Previous research shows that the germs - bacteria and other organisms - that live in the intestines (gut microbiome) are important to how well immune systems work, and that what people eat changes their gut microbiome. The investigators want to study whether a certain diet - based on the principles of the Mediterranean Diet - will improve arthritis for children and whether it was changes in the microbiome that led to improvement. Fifty-four participants in this study will change their diet for an 8-week period, and will have the option of remaining on the diet for an additional 4 weeks. At three time points during the study (beginning, 8 weeks, and 12 weeks), participants will provide stool and blood samples, will complete questionnaires about diet and other aspects of lifestyle and health, and will complete a disease assessment by a clinician. From collecting all these samples and information, the investigators will be able to determine if the diet was successful in improving disease activity in children with arthritis and if the gut microbiome was changed as well. This study will help the investigators figure out if a larger, and more definitive, study like this is possible to do in children with arthritis and will help the investigators design a bigger multinational study to confirm how diet affects disease outcomes and the microbiome in children with arthritis. If successful, this research will provide scientific knowledge to help families make their way through this difficult to- navigate topic.

The proposed study aims to evaluate the effectiveness of hypnotherapy as a non-pharmacological intervention for managing pain and anxiety during needle-related medical procedures in children aged 5 to 17 years. This research addresses a significant gap in pediatric healthcare, where painful procedures often induce distress and long-term anxiety, leading to avoidance of necessary medical care. Conventional pain management strategies primarily rely on pharmacological methods, which may pose risks and side effects. Thus, exploring safe and effective alternatives, such as hypnotherapy, is crucial.The target group for this randomized controlled trial includes children scheduled for painful procedures, such as injections or blood sampling. Participants will be randomly assigned to either the hypnotherapy group, receiving tailored sessions conducted by trained hypnotherapists, or the standard of care group, which will involve conventional pain management techniques. The study will assess primary outcomes, including anxiety levels and pain perception, before, during, and after the procedures using validated scales. Key activities of the project include conducting individualized hypnotherapy sessions, monitoring anxiety and pain levels through structured assessments, and analyzing the data to determine the effectiveness and feasibility of hypnotherapy. Secondary objectives will explore potential long-term benefits and safety concerns associated with hypnotherapy. If successful, this study could significantly enhance pediatric pain management practices, reduce reliance on pharmacological interventions, and improve the overall healthcare experience for children. The findings may also inform broader healthcare policies regarding non-pharmacological pain management strategies in pediatric settings.
