Spontaneous polarization without spatial cues, or symmetry breaking, is a fundamental problem of spatial organization in biological systems. This question has been extensively studied using yeast models, which revealed the central role of the small GTPase switch Cdc42. Active Cdc42‐GTP forms a coherent patch at the cell cortex, thought to result from amplification of a small initial stochastic inhomogeneity through positive feedback mechanisms, which induces cell polarization. Here, I review and discuss the mechanisms of Cdc42 activity self‐amplification and dynamic turnover. (...) A robust Cdc42 patch is formed through the combined effects of Cdc42 activity promoting its own activation and active Cdc42‐GTP displaying reduced membrane detachment and lateral diffusion compared to inactive Cdc42‐GDP. I argue the role of the actin cytoskeleton in symmetry breaking is not primarily to transport Cdc42 to the active site. Finally, negative feedback and competition mechanisms serve to control the number of polarization sites. (shrink)

In June 2021, the BMA published its report on moral distress and moral injury in UK doctors.1 The report includes definitions of the terms ‘moral distress’ and ‘moral injury’ as well as a summary of how the concepts have developed over time. There is also an analysis of the BMA’s pan-profession survey of moral distress and moral injury of doctors in the UK, the first of its kind. The impact of COVID-19 and recommendations for tackling moral distress also feature. Many (...) may be unfamiliar with the concepts of ‘moral distress’ and ‘moral injury’. These terms are relatively new, and debate is ongoing in academic circles on the best way to understand them.2 Some use the terms interchangeably. The BMA defines moral distress as the psychological unease generated where professionals identify an ethically correct action to take but are constrained in their ability to take that action. Even without an understanding of the morally correct action, moral distress can arise from the sense of a moral transgression. More simply, it is the feeling of unease stemming from situations where institutionally required behaviour does not align with moral principles. This can be as a result of a lack of power or agency, or structural limitations, such as insufficient staff, resources, training or time. The individual suffering from moral distress need not be the one who has acted or failed to act; moral distress can be caused by witnessing moral transgressions by others. Moral injury can arise where sustained moral distress leads to impaired function or longer-term psychological harm. Moral injury can produce profound guilt and shame, and in some cases also a sense of betrayal, anger and profound ‘moral disorientation’. It has also been linked to severe mental health issues. There is increasing recognition across the UK of the problem …. (shrink)

In people with chronic low back pain, maladaptive structural and functional changes on a cortical level have been identified. On a functional level, somatosensory cortical excitability has been shown to be reduced in chronic pain conditions, resulting in cortical disinhibition. The occurrence of structural and/or functional maladaptive cortical changes in people with CLBP could play a role in maintaining the pain. There is currently no measurement protocol for cortical excitability that employs stimulation directly to the lower back. We developed a (...) protocol for the measurement of single pulse somatosensory evoked potential waveforms and paired-pulse behavior generated from sensory nerves of the lower back and quantified its test–retest reliability in a sample of 30 healthy individuals to gain insights into the normal variability of cortical responses, which could then be compared to results from people with CLBP. We investigated cortical excitability by measuring SEPs and PPB. PPB was defined as the ratio of the amplitude of the second cortical response divided by the first cortical response. A2s was determined by subtracting the response to single-pulse stimuli from the paired pulse stimuli response to account for linear superposition effects. The test–retest reliability of the protocol was very poor with no evidence of systematic bias but a high amount of random variability between sessions. There was no significant difference in the right side PPB for session 1 and session 2 ; mean session difference [ = −0.44 ; t = −1.17, p = 0.26]. The ICC3.1 for the outlier-removed right side PPB were 0.19 and 0.43 for left side PPB. This finding potentially has wider implications for PPB protocols. If these findings were replicated in other groups and other nerves, it would question the validity of this measure more generally. However, these findings are restricted to healthy people and sensory nerves of the lower back and may not be generalizable. (shrink)

At the time of writing the COVID-19 pandemic was entering its ninth month, with nearly 800 000 recorded fatalities and 22 million infections in 188 countries and territories.1 In previous ethics briefings2 we raised concerns about the possibility that demand for life-sustaining treatment would overwhelm supply, with a consequent requirement for health professionals to make challenging triage decisions. Fortunately, to date, these have largely not been realised, although there is a possibility that countries in which containment measures have been less-successful, (...) such as South Africa, may still be required to triage.3 Despite the successful ‘flattening of the curve’ in many countries, there is a wide consensus that we remain firmly within the pandemic. Enormous practical challenges remain. It is unclear whether the pandemic will ultimately take the form of two or more successive waves, or whether the patchwork of global responses will lead to a sustained slow ‘burn’ with sporadic flare-ups.4 Areas of uncertainty include whether infection confers some immunity, how long any such immunity might last, whether effective vaccines can be developed and if seasonal temperature fluctuations alter the spread of the virus. The pandemic will also be fundamentally shaped by the decisions that governments make and the extent to which their diktats are complied with by citizens. With the – possibly temporary – retreat of urgent clinical ethics issues, such as triage, opportunities have arisen to reflect on some of the ethical questions that underlie and structure the demanding policy decisions that governments are wrestling with. One of the early questions was how to balance the complex constellation of costs and benefits associated with lockdown. Countries that …. (shrink)

As we go to press, the threat of biological or chemical warfare in the Persian Gulf is no longer imminent. Yet the questions raised by the proposed use of “investigational drugs,” without informed consent, to protect U.S. troops remain. The article by Edmund G. Howe and Edward D. Martin presents the arguments that informed the Pentagon's thinking on the subject. It and the commentaries, by George J. Annas and Michael A. Grodin, and Robert J. Levine, explore, among others, issues (...) of informed consent, of distinguishing ‘research’ and ‘treatment,’ and of the nature and extent of the autonomy of military personnel.—B‐JC, HLN. (shrink)

Recent studies have proposed that the executive advantages associated with bilingualism may stem from language-switching frequency rather than from bilingualism per se (see for example, Prior & Gollan, 2011). Barbu, Gillet, Orban and Poncelet (2018) showed that high-frequency language switchers outperformed low-frequency switchers on a mental flexibility task but not on alertness or response inhibition tasks. The aim of the present study was to replicate these results as well as to compare proficient high and low-frequency bilingual language switchers to a (...) control group of monolingual participants. Two groups of proficient bilingual adults (30 high-frequency language switchers and 21 low-frequency language switchers) and a group of 28 monolinguals participated in the study. The results showed superior mental flexibility skills in high-frequency language switchers compared to low-frequency switchers and monolinguals; furthermore, the two latter groups showed no difference in mental flexibility skills. These results provide novel support for the hypothesis that the so-called bilingual advantage is, in fact, a result of language-switching habits. (shrink)

In this work, on the one hand, we examined the relationship between emotional intelligence (EI) and empathy and, on the other, the relationship between emotional intelligence and nonverbal sensitivity, through two independent studies. The first study analyzed the relationship between dimensions of emotional intelligence and aspects of empathy, in a sample of 856 participants who completed two measures of EI, the Trait Meta-Mood Scale (TMMS) and the Trait Emotional Intelligence Questionnaire (TEIQue), and a measure of empathy, The Interpersonal Reactivity Index (...) (IRI). The results showed a similar pattern of significant positive relations in all the EI domains with empathic Perspective-taking, and significant negative relationships with empathic Personal Distress, except for the EI domain of Attention, which had a positive relationship. Stepwise multiple regression analyses showed that the dimension that best predicted empathic Perspective-taking and Empathic Concern was the Emotionality Factor; whereas Attention best predicted empathic Fantasy; and the Self-Control Factor best predicted Personal Distress, although negatively. Gender emerged as a predictor of three empathic aspects, Fantasy, Empathic Concern, and Personal Distress, with women obtaining higher scores than men in all of them. Age was the only predictor of Fantasy, with a negative relationship. The second study involved 646 people who completed the same measures of EI as the participants of the first study and the Mini-Profile of Nonverbal Sensitivity (Mini-PONS). The results showed some significant relationships between EI dimensions and the channels and quadrants of the MiniPONS. Stepwise multiple regression analyses showed that very few EI dimensions predicted nonverbal sensitivity, with Attention obtaining the best result. Both gender and age emerged as predictors, some in unique cases, of channels, quadrants and of the total score of nonverbal sensitivity; age had a negative relationship, and women obtained higher scores than men.

In a recent judgment1 the Court of Protection was highly critical of health professionals for continuing to provide clinically-assisted nutrition and hydration in the face of disagreement about the patient’s best interests, without seeking to resolve the issue. This hearing had been set up specifically to consider whether GU’s dignity had been properly protected, and if not why not, given concerns raised by the Official Solicitor about what she considered to be “a complete abrogation of responsibility to consider properly or (...) at all, and to determine whether it was in GU’s best interests and therefore lawful to continue to give him an invasive medical treatment, CANH.” In April 2014, at 63 years old and living in Thailand, GU sustained severe injuries after suffering from an electrocution accident. He sustained a cardiorespiratory arrest with a significant delay before cardiopulmonary resuscitation was started and was unconscious and unresponsive. In September 2014 he was transferred to the UK. In August 2018, GU’s brother made a request for a best interests decision concerning the continuation of CANH. The family met to discuss this and all except GU’s son, agreed that continuing CANH was not in GU’s best interests. In view of the fact that there was not unanimity among the family, a decision was made that CANH should continue. Commenting on this decision, Mr Justice Hayden said ‘the apparent assumption that in the face of family disagreement ‘ therefore will continue to be cared for by nursing staff ” is a troubling non sequitur’ and stressed that ‘family dissent to a medical consensus should never stand in the way of an incapacitated patients’ best interests being properly identified’. He also made clear that the responsibility for ensuring that a best interests assessment is undertaken rests with the …. (shrink)

As the COVID-19 vaccine roll out continues apace, in the higher-income countries at least, concerns remain about the level of vaccine coverage in some health and social care settings. Although most countries have seen a relatively high uptake of vaccination against COVID-19 among staff, there continue to be some pockets of hesitancy. The risk of outbreaks in settings with potentially very vulnerable patients has led some governments across Europe to consider, or to introduce, measures compelling healthcare staff to be vaccinated. (...) The justifiability of mandating the vaccination of healthcare professionals is a longstanding question but it has come to the fore in recent months following a resurgence of cases of COVID-19 and the prevalence of the more transmissible Delta variant. In deciding whether the introduction of a mandate is appropriate, states have to balance a range of ethical and practical considerations. A voluntary approach, backed up with education, respects healthcare workers’ autonomy to make private healthcare decisions, which is valued highly in liberal democracies. However, healthcare professionals also have an obligation to ensure that they do not present a risk of harm to their patients. Similarly, healthcare providers have a responsibility to take appropriate steps to minimise the risk of infection. Alongside balancing these rights and responsibilities, governments must also consider the potential consequences and risks of enforcing vaccine uptake. For example, there are concerns that a coercive approach could deepen mistrust and resentment among people who are genuinely fearful or hesitant. Moreover, a large number of refusals and the subsequent imposition of sanctions, such as suspension or redeployment, could affect the ability of providers to staff necessary services. In the UK, Wales, Northern Ireland and Scotland have all ruled out the introduction of compulsory vaccination. However, in July, the English Parliament voted through …. (shrink)

In December, the National Data Guardian 1 for health and care in England, Dame Fiona Caldicott, published the outcomes of a public consultation about the Caldicott Principles and the role of Caldicott Guardians.1 The Caldicott Principles are good practice guidelines which have been used by health and social care organisations in the UK since 1997 to ensure that people’s data are kept safe and used in an ethical way.2 The role of the Caldicott Guardian is well-established in the UK. Caldicott (...) Guardians are senior people which support the upholding of the Caldicott Principles within organisations. In response to views expressed during the consultation the NDG has added an eighth Caldicott Principle to the existing seven and will use her statutory powers to issue guidance about the appointment of Caldicott Guardians for health and adult social care organisations. The new eighth Caldicott Principle is: ‘Inform patients and service users about how their confidential information is used’. It provides that: > A range of steps should be taken to ensure no surprises for patients and service users, so they can have clear expectations about how and why their confidential information is used, and what choices they have about this. These steps will vary depending on the use: as a minimum, this should include providing accessible, relevant and appropriate information - in some cases, greater engagement will be required. The NDG explains that the introduction of the new principle was prompted by consideration of the role that the legal concept of ‘reasonable expectations’ should play in shaping the circumstances under which health and care data may be legitimately shared. The NDG does not envisage that this principle will establish reasonable expectations as a legal basis in its own right …. (shrink)

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further (...) questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)

On 7 April 2022 – coinciding with World Health Day – the British Medical Association launched its new report, Health and human rights in the new world order.1 Written during the global upheaval triggered by the COVID-19 pandemic, and published just weeks after the Russian invasion of Ukraine, the report responds to a range of emerging and intensifying threats to health-related human rights globally. As the report establishes, human rights in health and healthcare matter because human suffering, and its relief, (...) are fundamental moral issues. As relief of human suffering is the primary purpose of medicine, it follows that doctors and other health professionals are often active in times of human challenge and extremity. During conflict, humanitarian crises, and, as we have so recently seen, global public health emergencies, health professionals are essential to the response. But these crises – and the response to them – can put fundamental human rights and interests under pressure. The Russian invasion of Ukraine has seen sustained indiscriminate shelling of civilian infrastructure. Whether health facilities were directly targeted is moot – the indiscriminate nature of the assault means they will inevitably be hit. Not only is this a violation of the Geneva Conventions, it undermines fundamental human rights, not least of which the right to health. Destroying health infrastructure drives further suffering and delays post-conflict recovery. Public heath emergencies can rightly require draconian measures – social distancing, enforced isolation, location tracking, economic shutdown. Although we saw their necessity during the COVID-19 outbreak, concerns were raised about disproportionate restrictions on basic rights, including rights to privacy and liberty. Human Rights Watch drew attention to the way governments unlawfully exploited COVID-19 to crack down on fundamental rights.2 Although conflicts and public health emergencies are not new, the report also tracks a number of ….

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain (...) activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.

Experimental studies have suggested that variables such as aptness or conventionality are predictors of people’s preference for expressing a particular topic–vehicle pair as either a metaphor or a simile. In the present study, we investigated if such variables would also be predictive within a more naturalistic context, where other variables, such as the intention to include an explanation, may also influence people’s decision. Specifically, we investigated the production of metaphor and simile expressions on the Internet via the Google search engine (...) and checked for accompanying explanations, as well as the properties they expressed, to examine whether ratings such as aptness, conventionality, as well as participants’ own stated preference or the intention to produce an explanation, would predict which topic–vehicle pairs appeared more often as metaphor. We found that participants’ stated preference predicted metaphor dominance on the Internet, and that apt topic–vehicles occurred more often as metaphors. The explanations collected, however, occurred 82% of the time after similes, and familiar expressions were the most explained. Finally, comparing the properties expressed in these explanations to normed property lists, we found that simile explanations typically expressed a novel conception of the topic–vehicle relationship. Therefore, we found that Internet posters use metaphors to convey an apt relationship, as found in previous laboratory studies, but prefer using a simile frame when they want to express a relationship that readers will find novel.

Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from. With your eyes again fixed on the speaker, and the movement of her lips a clear sense of the source of the sound will (...) return. This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception. And this phenomenological observation is one what you can verify or disconfirm in your own case just by the slightest reflection on what it is like for you to listen to someone with or without visual contact with them.

Ever so often in the UK, there is a flurry of activity around the information requirements of donor-conceived individuals. In April 2013, it was the launch of a report from the Nuffield Council on Bioethics that brought the issue back to public consciousness.1Since 1991, information about treatment with donor gametes or embryos has been collected by the Human Fertilisation and Embryology Authority . Since then, over 35 000 donor-conceived individuals have been born through treatment in licensed clinics. Medical information and (...) information about donors’ appearance are collected by clinics, and donors are encouraged to put together a ‘pen portrait’ giving information about themselves for any resulting children. One focus of the new report is on improving the quality and quantity of information available about donors.Traditionally, gamete and embryo donations were practised on an anonymous basis, so that those born as a result of such donation may receive only non-identifying information about the donor when they reach the age of 18 . This changed in 2005 when donor anonymity was removed so that anyone donating after that time could be identified to individuals born as a result of the treatment. Those who have donated in the past are also able to reregister as identifiable donors. Much concern was expressed at the time that this would exacerbate the shortage of donors although the Nuffield Council on Bioethics reports that, 8 years on, those clinics that actively recruit donors appear to be successful in finding sufficient donors. The report recommends that the option of anonymous donation should not be reintroduced.A big issue of debate in the UK has been, and continues to be, whether parents should tell their …. (shrink)

Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

The innovative field of Regenerative Medicine (RM) is expected to extend the possibilities of prevention or early treatment in healthcare. Increasingly, clinical trials will be developed for people at risk of disease to investigate these RM interventions. These individuals at risk are characterised by their susceptibility for developing clinically manifest disease in future due to the existence of degenerative abnormalities. So far, there has been little debate about the ethical appropriateness of including such individuals at risk in clinical trials. We (...) discuss three main challenges of selecting this participant model for testing RM interventions: the challenge of achieving a proportional risk–benefit balance; complexities in the trial design in terms of follow-up and sample size; and the difficulty of obtaining informed consent due to the many uncertainties. We conclude that selecting the model is not ethically justifiable for first-in-man trials with RM interventions due to the high risks and uncertainties. However, the model can be ethically appropriate for testing the efficacy of RM interventions under the following conditions: interventions should be low risk; the degenerative abnormalities (and other risk factors) should be strongly related with disease within a short time frame; robust preclinical evidence of efficacy needs to be present; and the informed consent procedure should contain extra safeguards with regard to communication on uncertainties.

In February 2014, the Belgian Parliament passed legislation allowing euthanasia for terminally ill children of all ages by 86 votes to 44, with 12 abstentions. The Bill became law in early March after being signed by the King, making Belgium the first country in the world to abolish age restrictions for euthanasia. Previously, the youngest age at which euthanasia was permitted was 12 years old in The Netherlands.1Euthanasia was legalised in Belgium in 2002, and the new legislation introduces amendments to (...) the law extending euthanasia to minors in certain circumstances. Euthanasia is now permissible for children of all ages where the child has a “terminal and incurable illness”, experiences “constant and unbearable physical suffering”, and death is expected to occur within a “brief period”. The child must be deemed capable of making the decision, and have the agreement of their parents.Belgian law sets no timetable for euthanasia from the point at which the patient first expresses a wish to die. As with adults seeking euthanasia, any request must be made in writing. A physician and “outsider” brought in to give a second opinion must agree upon the diagnosis and prognosis, and a paediatric psychiatrist or psychologist must certify in writing that the child possesses “the capacity of discernment”. Following this, the child's physician must meet with the parents to inform them of the outcome of the consultation and ensure they are in agreement with the child's request. The child and the family must receive psychological care and support if so desired.The move provoked heated debate and divided the medical, legal and political professions in Belgium. A group of 160 of the country's paediatricians opposed a change in the law, citing concerns about the largely subjective assessment of the “capacity of discernment”, and drawing attention to advances in ….

Book description: The capacity to represent and think about time is one of the most fundamental and least understood aspects of human cognition and consciousness. This book throws new light on central issues in the study of the mind by uniting, for the first time, psychological and philosophical approaches dealing with the connection between temporal representation and memory. Fifteen specially written essays by leading psychologists and philosophers investigate the way in which time is represented in memory, and the role memory (...) plays in our ability to reason about time. They offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out fundamental issues concerning the phenomenology and epistemology of memory and our understanding of time. The chapters are arranged into four sections, each focused on one area of current research: Keeping Track of Time, and Temporal Representation; Memory, Awareness and the Past; Memory and Experience; Knowledge and the Past: The Epistemology and Metaphysics of Time. A general introduction gives an overview of the topics discussed and makes explicit central themes which unify the different philosophical and psychological approaches. (shrink)
