Observations of a species-record deep dive by a central Pacific female scalloped hammerhead shark (Sphyrna lewini).

A female scalloped hammerhead shark (Sphyrna lewini) conducted a species record deep dive to 1240 m in coastal-pelagic waters off Hawaii Island. This extends the deepest known depth range of the species by over 200 m (650 ft) and highlights the question of the extent to which deep-diving activity is mediated by physiological constraints, such as temperature and oxygen availability.

Advance decisions to refuse treatment and suicidal behaviour in emergency care: 'it's very much a step into the unknown'.

BACKGROUND: Complex challenges may arise when patients present to emergency services with an advance decision to refuse life-saving treatment following suicidal behaviour. AIMS: To investigate the use of advance decisions to refuse treatment in the context of suicidal behaviour from the perspective of clinicians and people with lived experience of self-harm and/or psychiatric services. METHOD: Forty-one participants aged 18 or over from hospital services (emergency departments, liaison psychiatry and ambulance services) and groups of individuals with experience of psychiatric services and/or self-harm were recruited to six focus groups in a multisite study in England. Data were collected in 2016 using a structured topic guide and included a fictional vignette. They were analysed using thematic framework analysis. RESULTS: Advance decisions to refuse treatment for suicidal behaviour were contentious across groups. Three main themes emerged from the data: (a) they may enhance patient autonomy and aid clarity in acute emergencies, but also create legal and ethical uncertainty over treatment following self-harm; (b) they are anxiety provoking for clinicians; and (c) in practice, there are challenges in validation (for example, validating the patient's mental capacity at the time of writing), time constraints and significant legal/ethical complexities. CONCLUSIONS: The potential for patients to refuse life-saving treatment following suicidal behaviour in a legal document was challenging and anxiety provoking for participants. Clinicians should act with caution given the potential for recovery and fluctuations in suicidal ideation. Currently, advance decisions to refuse treatment have questionable use in the context of suicidal behaviour given the challenges in validation. Discussion and further patient research are needed in this area.

N.K. chaired the National Institute for Health and Care Excellence (NICE) guideline development group for the longer-term management of self-harm and the NICE Topic Expert Group (which developed the quality standards for self-harm services).

Management of patients with an advance decision and suicidal behaviour: a systematic review.

BACKGROUND: The use of advance care planning and advance decisions for psychiatric care is growing. However, there is limited guidance on clinical management when a patient presents with suicidal behaviour and an advance decision and no systematic reviews of the extant literature. OBJECTIVES: To synthesise existing literature on the management of advance decisions and suicidal behaviour. DESIGN: A systematic search of seven bibliographic databases was conducted to identify studies relating to advance decisions and suicidal behaviour. Studies on terminal illness or end-of-life care were excluded to focus on the use of advance decisions in the context of suicidal behaviour. A textual synthesis of data was conducted, and themes were identified by using an adapted thematic framework analysis approach. RESULTS: Overall 634 articles were identified, of which 35 were retained for full text screening. Fifteen relevant articles were identified following screening. Those articles pertained to actual clinical cases or fictional scenarios. Clinical practice and rationale for management decisions varied. Five themes were identified: (1) tension between patient autonomy and protecting a vulnerable person, (2) appropriateness of advance decisions for suicidal behaviour, (3) uncertainty about the application of legislation, (4) the length of time needed to consider all the evidence versus rapid decision-making for treatment and (5) importance of seeking support and sharing decision-making. CONCLUSIONS: Advance decisions present particular challenges for clinicians when associated with suicidal behaviour. Recommendations for practice and supervision for clinicians may help to reduce the variation in clinical practice.

Low thrombin tissue sealant ARTISS (Baxter), in complex primary closure after Fournier's gangrene.

The following case report describes the reconstruction of Fournier's gangrene (FG) which failed initial conventional primary closure due to issues with wound edge friability, large dead spaces, and significant tension and shearing forces created by excess adipose tissue in the patient's groin. In the first reported case that could be found in the literature ARTISS (Baxter), a low thrombin concentration fibrin sealant was used as a tissue adhesive to close the large post FG debridement wound flaps and ensure enough working time to allow for precise wound edge approximation. Employing Artiss in the closure of the large wound allowed for successful healing where simple primary closure had failed, aided an expedient recovery and reduced post reconstructive morbidity.

Litigation Friends or Foes? Representation of 'P' before the Court of Protection.

This article argues that, properly analysed, the common law and the European Convention on Human Rights (ECHR) march hand in hand with the provisions of the Mental Capacity Act 2005 (MCA 2005) so as to impose a set of requirements on litigation friends acting for the subject of applications of proceedings before the Court of Protection ('P') which are very different to those currently understood by practitioners and the judiciary. The authors examine critically current practice and procedures and provide a set of proposals for reforms.

The right to life in a suicidal state.

This paper considers when the State must take positive steps to protect the right to life of a suicidal patient. Using recent developments across the Council of Europe which challenge the traditional 'ugly Samaritan' approach of many common law systems, it contends that whenever and wherever public authorities know or ought to know of a real and immediate risk to the life of an identifiable person, they must take reasonable precautions to minimise it. Even J. S. Mill's approach to liberty, it is suggested, would tolerate this limited degree of State interference. However, notions of autonomy and dignity, the unpredictability of human behaviour, and the need to avoid unduly burdening the State must influence what it means to act reasonably.

Healthcare scandals in the NHS: crime and punishment.

The Francis Report into failures of care at Mid Staffordshire NHS Foundation Trust Hospital documented a series of 'shocking' systematic failings in healthcare that left patients routinely neglected, humiliated and in pain as the Trust focused on cutting costs and hitting government targets. At present, the criminal law in England plays a limited role in calling healthcare professionals to account for failures in care. Normally, only if a gross error leads to death will a doctor or nurse face the prospect of prosecution. Doctors and nurses caring for patients under the Mental Health Act 1983 and the Mental Capacity Act 2005 may however be prosecuted for wilful neglect of a patient. In the light of the Francis Report, this article considers whether the criminal offence of wilful neglect should be extended to a broader healthcare setting and not confined to mental healthcare.
