Long-term enteral nutrition via gastrostomy is a relatively common medical intervention for patients at risk of malnutrition who have an accessible and functioning gastrointestinal tract. There are clear clinical guidelines describing the principles of practice as well as numerous retrospective and non-randomised controlled studies and case series. However, fewer publications impart advice and guidance regarding the management and ‘patient selection’ for these interventions. The following article provides a combination of the author’s views and the evidence base.

Hepatitis C virus (HCV) infection remains an important global health concern. It is estimated that there are approximately 50 million people infected with HCV globally, with around 1 million new infections each year and about 242,000 deaths annually attributed to HCV-related complications. Most acute HCV infections (55–85%) become chronic due to the virus’s effective evasion strategies, with spontaneous clearance being rare once chronicity is established. This condition often progresses silently, with many individuals unaware of their infection until advanced liver damage has occurred. If left untreated, HCV can lead to severe complications, including liver cirrhosis and hepatocellular carcinoma (HCC). HCV transmission occurs mainly through percutaneous exposure to infected blood. HCV can also spread from mother to infant (vertical transmission) and, less frequently, via sexual contact.1,2 In recent years, the introduction of oral direct-acting antivirals (DAAs), with remarkable safety and effectiveness profiles, has led to a sustained virological response (SVR) in virtually all (>97%) HCV-infected patients, regardless of HCV genotype or disease stage. However, significant barriers remain, such as issues with diagnosis, access to treatment and awareness of the disease.

Here, we discuss some of the misconceptions in HCV management and provide a practical management approach grounded in evidence and clinical experience.

Jaundice can be caused by abnormalities in any of the steps comprising the formation, metabolism and excretion of bilirubin. In addition, these processes may be functioning properly, but jaundice can be seen because of an obstruction of the biliary tree at any point, from its intrahepatic origins to its end at the ampulla of Vater. For this reason, it is clear that numerous conditions can result in jaundice. When faced with a patient presenting with jaundice a reasonable and careful diagnostic approach is, therefore, warranted to elucidate the underlying cause of this sign. Conventional wisdom may be that “jaundice by itself never killed anyone,” but it is imperative to find the cause as soon as possible, as prompt intervention saves lives in many cases.

Colonoscopy is a complex procedure requiring both technical and non-technical skills. Performing colonoscopy also requires manual and visuospatial skills, interpretation of pathology, patient communication and a wide range of advanced therapeutic technologies. The clinical intention of colonoscopy must be individualised, and diagnostic and/or therapeutic intent rationalised, given the procedures invasive nature and associated risks. Furthermore, each colonoscopy differs due to patient factors, sedation strategy, anatomical configuration, technical challenges and endoscopist skills. Endoscopists must, therefore, demonstrate a wide range of expertise whilst working effectively in a team to manage the patient safely. It is not, therefore, surprising that mistakes in colonoscopy can occur. This article focuses on six common mistakes in colonoscopy that can be avoided to improve the procedure's safety and deliver a high-quality procedure. This, in turn, can reduce the rates of post-colonoscopy colorectal cancer (PCCRC) and improve patient experience and adherence to colonoscopy surveillance programmes. This article is based on evidence in conjunction with our collective clinical and research experience of errors in endoscopy and patient safety.

Ulcerative colitis (UC) is a lifelong inflammatory bowel disease (IBD) of unknown origin characterized by alternating flare and remission periods. An acute severe episode, so-called acute severe UC (ASUC), may happen in approximately one-quarter of patients during their life.1 Notably, more than 25% of ASUC episodes correspond to the index presentation of the disease. Patients with ASUC should be promptly identified by the modified Truelove and Witts criteria recommended by the most recent international guidelines and admitted rapidly to a digestive unit. Indeed, ASUC is a life-threatening condition still leading to a 1% death rate in Western countries. In the current article, we will discuss the most frequent and/or relevant mistakes in managing patients admitted for an ASUC episode and how to avoid them. The manuscript is based on the available evidence and expert opinion when evidence is lacking.
