Many tertiary inflammatory bowel disease (IBD) centers recognize that a structured transition program is fundamental for an IBD unit. However, the path to ensuring a seamless transition for all stakeholders is often fraught with challenges. In this review, we go through current evidence, identify the requirementsof a successful transition program, and the barriers to seamless transfer. We also aim to shed light on differences in needs between the Western and Asian adolescent IBD populations. Majority of healthcare providers viewed having a structured transition program to be very important. The lack of a standard protocol led us to come up with a list of requirements ofa successful program. These include: multidisciplinary team meetings, alternating visits between the adultand pediatric clinics, proper documentation of records, and determining the ideal timing for transfer. The difficulties forthe Asian adolescent IBD population may be attributed to the reliance on parental support to make decisions regarding medicaltreatment. Lastly, there are various physician, patient and disease factors which are barriers to seamless transition. These includethe lack of proper documentation, and lack of patient self-efficacy. We also propose a standardized template for documentation of medical records for IBD patients.

Background/Aims Transforming growth factor-β1 (TGF-β1) induction of epithelial-mesenchymal transition (EMT) is one of the mechanisms by which colorectal cancer (CRC) cells acquire migratory and invasive capacities, and subsequently metastasize. Parthenolide (PT) expresses multiple anti-cancer and anti-inflammatory activities that inhibit nuclear factor κB by targeting the IκB kinase complex. In the present study, we aimed to investigate whether PT can inhibit TGF-β1-induced EMT in CRC cell lines.
Methods HT-29 and SW480 cell lines were used in the experiment. Cell viability was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and sub-G1 analysis was measured by flow cytometry. The induction of EMT by TGF-β1 and inhibition of the process by PT was analyzed by phase contrast microscopy, wounding healing, cellular migration and invasion assays, and Western blotting.
Results TGF-β1 inhibits HT-29 cell proliferation, but has no effect on SW480 cell proliferation; different concentrations of TGF-β1 did not induce apoptosis in HT-29 and SW480 cells. PT attenuates TGF-β1-induced elongated, fibroblast-like shape changing in cells. PT inhibits TGF-β1-induced cell migration and cell invasion. In addition, other EMT markers such as β-catenin, Vimentin, Snail, and Slug were suppressed by PT, while E-cadherin was increased by PT.
Conclusions Our findings show that PT inhibits TGF-β1-induced EMT by suppressing the expression of the mesenchymal protein and increasing expression of the epithelial protein. These findings suggest a novel approach for CRC treatment by suppression of TGF-β1-induced EMT.

The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient’s developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients’ knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients’ adherence to therapy, maintain the appropriate health status, improve patients’ self-management, and promote self-reliance among patients.
