Hepatitis B virus (HBV) infection is the most common chronic viral infection in the world. Despite the availability of a preventative vaccine, more than 250 million people worldwide are chronically infected with HBV. The complications of chronic HBV infection—cirrhosis and hepatocellular cancer (HCC)—account for more than 850,000 deaths per year. HBV is transmitted haematogenously and sexually, with the majority of HBV infections being transmitted vertically (or perinatally) in high prevalence regions. HBV infection acquired at birth or in early childhood results in chronicity in >95% of cases, whereas only 5–10% of those who are infected in adulthood will progress to chronic infection. 

Children and adolescents with chronic diseases requiring lifelong care face unique challenges that affect their daily lives and those of their families. Initially, these patients receive specialized care in pediatric facilities, where parents play a key role in treatment decisions. However, transitioning to adult healthcare facilities is inevitable, and this process, recognized as crucial years ago, involves moving adolescents with chronic conditions from child-centered to adult-oriented care. This transition can be complicated by varying age limits for pediatric care and the scarcity of adult care centers with specific expertise. The transition often requires cooperation between different centers or even countries due to patient mobility. The transition phase is critical, as it can lead to loss of follow-up, treatment suspension, and increased risks of complications or disease relapse. Beyond medical management, various factors influence the long-term prognosis of chronic conditions, making a well-organized transition program essential. While many hospitals have implemented transition models with mixed results in satisfaction, disease control, and follow-up adherence, there are frequent shortcomings in the process. This Mistakes In article will outline eight common mistakes made during the transition from pediatric to adult care, supported by literature and professional experience.

The relationship between nutrition and inflammatory bowel disease (IBD) has been an area of substantial interest and research for many decades now. Evidence-based nutritional strategies are being utilised as a key part of the therapeutic armamentarium in Crohn’s disease for both induction and maintenance, as primary and adjuvant treatment methods. Exclusive enteral nutrition, for instance, is well established in the treatment of paediatric IBD and adult centres are increasingly incorporating it into treatment models as an effective, drug-free alternative.  The role for partial enteral nutrition and Crohn’s disease specific diets are also being more clearly elucidated. Used appropriately, and through engagement with dietetic support services, nutritional therapies can not only achieve the IBD treatment ‘targets’ but serve to optimise other vital aspects of care, such as growth, bone health, body composition and overall patient well-being. Here we discuss some of the mistakes that are frequently made in the area of nutritional management of IBD. The discussion is evidence based, with key references incorporated for further analysis beyond the scope of this article, and combines several decades of leading clinical and research experience in the area of nutrition and IBD from the authors. 

Peritoneal malignancies represent a complex and often misjudged clinical challenge. Historically synonymous with a terminal diagnosis, the advent of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) radically altered the prognosis for selected patients. However, progress has been jeopardised by a series of recurring and preventable errors in diagnosis, staging, and treatment selection. This article delineates the ten most critical pitfalls in managing peritoneal surface malignancies. For each pitfall, we provide evidence-based explanations, concrete clinical examples, and strategic recommendations for avoidance. We emphasise the pivotal role of early multidisciplinary discussion, precise imaging, and timely referral to high-volume expert centres to optimise patient outcomes and offer curative intent where previously there was none.
