Catheter-related thrombosis (CRT) is a serious complication associated with home parenteral nutrition (HPN) in children chronic intestinal failure (CIF). Guidelines on pediatric HPN state that there insufficient evidence to advocate the prophylactic use of CRT. Aim evaluate efficacy and safety anticoagulation preventing CRT HPN. We performed prospective, international, multicenter study across three expertise centers. Children aged 0-18 years were included divided into two groups: 1)...

Life expectancy of children with chronic intestinal failure (CIF) on home parenteral nutrition has greatly improved. Children are now able to grow into adulthood which requires transfer from pediatric adult health care. A guideline for structured transition is lacking and the demand a more standardized care this patient group necessary. Therefore, we investigated perceptions professionals various disciplines working in specific field, concerning effective interventions regarding

In research on pediatric chronic intestinal failure, heterogeneity in reported definitions and outcomes exists. This leads to a risk of reporting bias impossibility evidence synthesis. Also, should be relevant both healthcare providers patients their parents. Therefore, the aim this study is create core outcome set (COS) used studies failure.Candidate were selected from recent systematic review. A three-round Delphi among key stakeholders consensus meeting with an expert panel undertaken...
