ACTIVE-IBD Study: Physical Activity and Sleep in Paediatric Inflammatory Bowel Disease
Inflammatory Bowel DiseasesExerciseAssessment of physical activity on children with Inflammatory Bowel Disease using questionnaires and wrist watch based activity monitors. The participants will be recruited from paediatric IBD clinics and will undergo questionnaires to assess their activity level, disease activity and quality of life scores. The participants will then be invited to wear a wrist based accelerometer for a week. The participants will complete a physical activity diary, food diary and stool chart at the same time. Results will be analysed to see the level of physical activity and assess if the participants are meeting the recommended level of physical activity

Cognitive Impairment and Affective Mood Disorders in Patients With IBD
Inflammatory Bowel DiseasesMild Cognitive Impairment4 moreThe aim is to evaluate the presence of mild cognitive impairment (MCI) in patients with inflammatory bowel disease (IBD). This will be done by cognitive tests. Along them, screening for depression, anxiety and stress will be done. A blood sample for determining serum values of homocysteine, protein S100-B, amyloid and BDNF will be stored. Patients will be followed-up for 2 years.

Multi-Center African-American Inflammatory Bowel Disease Study (MAAIS)
Inflammatory Bowel DiseaseThe investigators are doing the research to discover genes that cause Inflammatory Bowel Disease (IBD) specifically in the African American population. African Americans with or without Crohn's disease or ulcerative colitis are eligible to join. If you agree to join the study, the investigators will ask for information about your health. The investigators will also ask you to give us a blood sample so that they may discover the genes that cause IBD. The blood sample may be collected at Johns Hopkins or any local facility convenient to you.

Sleep Disorder in Inflammatory Bowel Disease and Its Association With Disease Activity
Sleep DisorderInflammatory Bowel DiseasesRecently, an association between active inflammatory bowel disease (IBD) and poor sleep quality has been proposed; however, the causal relationship has not yet been established. This study aimed to investigate prevalence of poor sleep quality in IBD and association with disease activity by subjective and objective measures. Prospective observational study is conducted with expected sample size of 100 patients. Participants are classified into active and inactive disease status according to standard IBD severity assessment measures. Demographic data, disease activity, quality of life, sleep questionnaire (validated PSQI questionaire), and seven-day sleep data acquired from ambulatory wrist actigraphy were obtained. Association between sleep quality and disease activity will be analyzed.

Diverse Ancestry Study in IBD
Ulcerative ColitisHealthy2 moreObjective: To use clinical, genetic and genome analysis to better understand and define the genetic and environmental factors that contribute to IBD in diverse ancestries: African, African American, Black, Afro-Caribbean, Afro-Latino/a/x, Latino/a/x, Hispanic, or any other Black or Latin or indigenous ancestry.

Research on Gut Microbiome and Metabolomics Alterations in C.Difficile Infected IBD Patients
Inflammatory Bowel DiseasesClostridium Difficile Infections1 moreThe goal of this research is to compare alterations of gut microbiota and fecal metabolomics alterations between inflammatory bowel disease patients infected with or without Clostridioides difficile. The main questions it aim to answer are: which bacterial genus or fecal metabolites can discriminate IBD patients infected or more likely to be infected with Clostridioides difficile and their role in the pathogenesis of Clostridioides difficile. type of study: observational study participant population/health conditions population diagnosed with Ulcerative colitis or Crohn's disease Having diarrhea Participants will be included in this research. If there is a comparison group: Researchers will compare healthy people without IBD or any diarrhea to see if disease or diarrhea would affect the gut microbiota and metabolites.

Correlation of Genetic Susceptibility Genes to Inflammatory Bowel Disease in Chinese Han Population...
Gene AbnormalityInflammatory Bowel Disease1 moreThe pathogenesis of IBD is still unclear, and the disease characteristics of IBD patients are affected by genetic susceptibility genes. Therefore, this study aims to explore the relationship between genetic susceptibility genes of IBD and the pathogenesis of IBD in Chinese Han population, in order to clarify the pathogenesis of IBD and provide basis for individualized treatment of IBD.

Digestive Biobank for Exploring Microbiota-host Interactions
Inflammatory Bowel DiseasesCrohn Disease3 moreConstitution of a biobank of tissues, whole blood and plasma samples and stools to identify markers associated with treatment response, postoperative morbidity including neuro-cognitive and mood complications and prognosis of Inflammatory Bowel disease or colorectal cancer.

Endoscopic Scoring System Utilization in Inflammatory Bowel Disease
Inflammatory Bowel DiseasesInflammatory bowel diseases comprise two distinctive entities: Crohn's disease and ulcerative colitis. During the last decade, endoscopic assessment of inflammation has become relevant since it is a prognostic factor. As a consequence, therapeutic targets now contemplate mucosal healing as part of the goals to be achieved. Endoscopic scores for Crohn's disease and ulcerative colitis have been developed to objectively assess the mucosal inflammatory activity. Although they may have some limitations, these scores have been widely accepted in referral centers, especially since they have been adopted as standard evaluation in inflammatory bowel disease clinical trials . However, their use in the setting of endoscopic practice outside centers with a high volume or with less experience in clinical trials is not known.

Risk Factors for Bowel Dysfunction at Preschool and Early Childhood Age in Children With Hirschsprung...
Bowel DysfunctionHirschsprung Disease3 moreBowel dysfunction has been proven as the most common complication after pull-through(PT) of Hirschsprung disease(HD) ,which may persist to adulthood and lead to social problems.The reason of bowel dysfunction is complicated and the risk factors were not defined.
