Nutrition support involves the use of oral supplements, enteral tube feeding or parenteral nutrition. These interventions are considered when oral intake alone fails to meet nutritional requirements. Special diets and oral supplements are usually the first approach to managing malnutrition; however, their role becomes limited when oral intake is restricted or if swallowing is unsafe. Enteral tube feeding or parenteral nutrition are alternative means of providing nutrition support for this select group of patients. Percutaneous endoscopic gastrostomy (PEG) feeding was introduced into clinical practice in 1980. It describes a feeding tube placed directly into the stomach under endoscopic guidance. It is an established means of providing enteral nutrition to those who have functionally normal gastrointestinal tracts, but who cannot meet their nutritional requirements due to inadequate oral intake. The intervention is usually reserved when nutritional intake is likely to be inadequate for more than 4–6 weeks. Although the benefits of PEG have been shown for a select group of patients, there currently exists concerns about the increasing frequency of this intervention, and also uncertainty about the long-term benefits for certain patients. The 2004 UK National Confidential Enquiry into Patient Outcome and Death report emphasised this concern, with almost a fifth of PEG being undertaken for futile indications that negatively influenced morbidity and mortality. The present review paper discusses the indications for, controversies surrounding and complications of gastrostomy feeding and provides practical advice on optimising patient selection for this intervention.

Facial transplantation is emerging as a therapeutic option for self-inflicted gunshot wounds. The self-inflicted nature of this injury raises questions about the appropriate role of self-harm in determining patient eligibility. Potential candidates for facial transplantation undergo extensive psychosocial screening. The presence of a self-inflicted gunshot wound warrants special attention to ensure that a patient is prepared to undergo a demanding procedure that poses significant risk, as well as stringent lifelong management. Herein, we explore the ethics of considering mechanism of injury in the patient selection process, referring to the precedent set forth in solid organ transplantation. We also consider the available evidence regarding outcomes of individuals transplanted for self-inflicted mechanisms of injury in both solid organ and facial transplantation. We conclude that while the presence of a self-inflicted gunshot wound is significant in the overall evaluation of the candidate, it does not on its own warrant exclusion from consideration for a facial transplantation.

Background: Cognitive Behaviour Therapy self-help has been recommended in the NICE guidelines for the treatment of anxiety and depression. However, little is known about who benefits from self-help and the potential drawbacks and problems of using this approach. Aims: To address the current gap in knowledge, we contacted accredited BABCP practitioners to examine practitioner use and attitudes to self-help, current trends of use, and to identify possible problems with this therapy. Method: A 50% random sample of all accredited BABCP practitioners was approached, and the overall response rate for the survey was 57.6%. Results: Self-help materials were seen positively by therapists and were used by 99.6%, mainly as an adjunct to individual therapy. Only 38.2% had been trained in the use of self-help, with those trained being more likely to recommend self-help. Higher levels of patient motivation, credibility, likely adherence, self-efficacy and a lower degree of hopelessness were the five factors identified by more than 70% of respondents as predicting successful patient outcome with self-help. Non-compliance and a lack of detection of a worsening of the patient's clinical state due to reduced therapist contact were viewed as being the most important problems with self-help by more than 70% of respondents. Conclusions: Preferable patient characteristics for self-help have been identified, as have potential problems and adverse consequences.

Ambulatory surgery is growing worldwide. The challenge of providing anaesthesia for longer and more complex surgery in sicker and elderly patients is a reality. To maintain the safety and good outcomes of ambulatory anaesthesia, high-risk patients will need to be evaluated carefully. Anaesthetic techniques that use short-acting drugs and minimize postoperative morbidity and mortality should become the focus. Policies on management of postoperative pain, nausea, vomiting, voiding and discharge from hospital will maintain good outcome measures.

Clinical practice guidelines are expanding their scope of authority from clinical decision making to collective policy making, and promise to gain ground as resource allocation tools in coming years. A close examination of how guidelines approach patient selection criteria offers insight into their ethical implications when used as resource allocation or rationing instruments. The purposes of this paper are: a) to examine the structure of allocative reasoning found in clinical guidelines; b) to identify the ethical principles implied and compare how guidelines enact these principles with how explicit systems-level rationing exercises and health policy analyses have approached them; and c) to offer some preliminary suggestions for how these ethical issues might be addressed in the process of guideline development. The resulting framework can be used by guideline developers and users to understand and address some of the ethical issues raised by guidelines for the use of scarce technologies.
