Cognitive limits of larval Drosophila: testing for conditioned inhibition, sensory preconditioning, and second-order conditioning.

Drosophila larvae are an established model system for studying the mechanisms of innate and simple forms of learned behavior. They have about 10 times fewer neurons than adult flies, and it was the low total number of their neurons that allowed for an electron microscopic reconstruction of their brain at synaptic resolution. Regarding the mushroom body, a central brain structure for many forms of associative learning in insects, it turned out that more than half of the classes of synaptic connection had previously escaped attention. Understanding the function of these circuit motifs, subsequently confirmed in adult flies, is an important current research topic. In this context, we test larval Drosophila for their cognitive abilities in three tasks that are characteristically more complex than those previously studied. Our data provide evidence for (i) conditioned inhibition, as has previously been reported for adult flies and honeybees. Unlike what is described for adult flies and honeybees, however, our data do not provide evidence for (ii) sensory preconditioning or (iii) second-order conditioning in Drosophila larvae. We discuss the methodological features of our experiments as well as four specific aspects of the organization of the larval brain that may explain why these two forms of learning are observed in adult flies and honeybees, but not in larval Drosophila.

Development, implementation and evaluation of an evidence-based paediatric early warning system improvement programme: the PUMA mixed methods study.

BACKGROUND: Paediatric mortality rates in the United Kingdom are amongst the highest in Europe. Clinically missed deterioration is a contributory factor. Evidence to support any single intervention to address this problem is limited, but a cumulative body of research highlights the need for a systems approach. METHODS: An evidence-based, theoretically informed, paediatric early warning system improvement programme (PUMA Programme) was developed and implemented in two general hospitals (no onsite Paediatric Intensive Care Unit) and two tertiary hospitals (with onsite Paediatric Intensive Care Unit) in the United Kingdom. Designed to harness local expertise to implement contextually appropriate improvement initiatives, the PUMA Programme includes a propositional model of a paediatric early warning system, system assessment tools, guidance to support improvement initiatives and structured facilitation and support. Each hospital was evaluated using interrupted time series and qualitative case studies. The primary quantitative outcome was a composite metric (adverse events), representing the number of children monthly that experienced one of the following: mortality, cardiac arrest, respiratory arrest, unplanned admission to Paediatric Intensive Care Unit, or unplanned admission to Higher Dependency Unit. System changes were assessed qualitatively through observations of clinical practice and interviews with staff and parents. A qualitative evaluation of implementation processes was undertaken. RESULTS: All sites assessed their paediatric early warning systems and identified areas for improvement. All made contextually appropriate system changes, despite implementation challenges. There was a decline in the adverse event rate trend in three sites; in one site where system wide changes were organisationally supported, the decline was significant (ß = -0.09 (95% CI: - 0.15, - 0.05); p = < 0.001). Changes in trends coincided with implementation of site-specific changes. CONCLUSIONS: System level change to improve paediatric early warning systems can bring about positive impacts on clinical outcomes, but in paediatric practice, where the patient population is smaller and clinical outcomes event rates are low, alternative outcome measures are required to support research and quality improvement beyond large specialist centres, and methodological work on rare events is indicated. With investment in the development of alternative outcome measures and methodologies, programmes like PUMA could improve mortality and morbidity in paediatrics and other patient populations.

Pro-judge study: Nurses' professional judgement in nurse staffing systems.

AIMS: Aim of this study is to better understand the role of nurses' professional judgment in nurse staffing systems. DESIGN: Qualitative comparative case study design of nurse staffing systems in England and Wales. METHODS: Data will be collected through a variety of sources: individual interviews, observations of relevant meetings and analysis of key documents. Ethical approval for the study was granted in August 2020 from The Healthcare Research Ethics Committee (SREC reference: REC741). Data generation will be informed by science and technology studies and practice theories. DISCUSSION: Ensuring adequate numbers of nurses are available to care for patients in response to shifting demand is an international policy priority. Emerging evidence on the use of formal workforce planning methodologies across the developed world highlights both the centrality of nurses' professional judgement in nurse staffing methodologies and the urgent need for theoretically informed research to better understand and conceptualise its contribution to decision-making. This study is designed to address this gap in understanding. It takes advantage of nurses' experiences of managing the service and staffing impacts of the Covid-19 pandemic and differences in strategic approaches to nurse staffing systems between England and Wales. IMPACT: The research will: make visible the knowledge and skills that underpin professional judgement in nurse staffing decisions and provide a conceptual language with which to articulate this; lay the foundations for evidence-based programmes of nurse education and continuing professional development; furnish the evidence to inform the development of nurse-led decision support tools to augment professional judgement; and generate wider insights into the effectiveness of nurse staffing systems in practice.

Are youth suicide memorial sites on Facebook different from those for other sudden deaths?

To explore possible distinctive features of online memorials for youth suicides, amid concerns about glorification, we compared public Facebook memorials for suicides and road traffic accident deaths, using Linguistic Inquiry and Word Count software. People who posted on memorial sites wrote at greater length about suicides, using longer words and more quotation marks. Words suggesting causation and achievement were more prevalent in suicide memorials. Thematic content for the two types of death was more similar than different. Suicide memorial posts had more tentative words, non-fluencies, and question marks, suggesting that people were struggling to make sense of these deaths.

A prospective, mixed-methods, before and after study to identify the evidence base for the core components of an effective Paediatric Early Warning System and the development of an implementation package containing those core recommendations for use in the UK: Paediatric early warning system - utilisation and mortality avoidance- the PUMA study protocol.

BACKGROUND: In hospital, staff need to routinely monitor patients to identify those who are seriously ill, so that they receive timely treatment to improve their condition. A Paediatric Early Warning System is a multi-faceted socio-technical system to detect deterioration in children, which may or may not include a track and trigger tool. It functions to monitor, detect and prompt an urgent response to signs of deterioration, with the aim of preventing morbidity and mortality. The purpose of this study is to develop an evidence-based improvement programme to optimise the effectiveness of Paediatric Early Warning Systems in different inpatient contexts, and to evaluate the feasibility and potential effectiveness of the programme in predicting deterioration and triggering timely interventions. METHODS: This study will be conducted in two district and two specialist children's hospitals. It deploys an Interrupted Time Series (ITS) design in conjunction with ethnographic cases studies with embedded process evaluation. Informed by Translational Mobilisation Theory and Normalisation Process Theory, the study is underpinned by a functions based approach to improvement. Workstream (1) will develop an evidence-based improvement programme to optimise Paediatric Early Warning System based on systematic reviews. Workstream (2) consists of observation and recording outcomes in current practice in the four sites, implementation of the improvement programme and concurrent process evaluation, and evaluation of the impact of the programme. Outcomes will be mortality and critical events, unplanned admission to Paediatric Intensive Care (PICU) or Paediatric High Dependency Unit (PHDU), cardiac arrest, respiratory arrest, medical emergencies requiring immediate assistance, reviews by PICU staff, and critical deterioration, with qualitative evidence of the impact of the intervention on Paediatric Early Warning System and learning from the implementation process. DISCUSSION: This paper presents the background, rationale and design for this mixed methods study. This will be the most comprehensive study of Paediatric Early Warning Systems and the first to deploy a functions-based approach to improvement in the UK with the aim to improve paediatric patient safety and reduce mortality. Our findings will inform recommendations about the safety processes for every hospital treating paediatric in-patients across the NHS.

Among friends: a qualitative exploration of the role of peers in young people's alcohol use using Bourdieu's concepts of habitus, field and capital.

Drinking is viewed by young people as a predominantly social activity which provides an opportunity for entertainment and bonding with friends. Using Bourdieu's concepts of habitus, field and capital, this article explores young people's attitudes and beliefs around alcohol use, influences on behaviour, and the role of peers, with a view to informing the development of preventive interventions. Semi-structured interviews were conducted with 28 young people aged 18-20 in the south west of England. We describe how friends were integral in drinking experiences, and drinking with friends was equated with fun and enjoyment. In this way, the desire for social and symbolic capital appeared to be a key motivator for adolescent drinking. Critically, however, wider cultural norms played the predominant role in shaping behaviour, via the internalisation of widely accepted practice and the subsequent externalisation of norms through the habitus. Applying Bourdieu's theory suggests that population-level interventions that regulate alcohol consumption, and thus disrupt the field, are likely to facilitate behaviour change among young people by driving a response in habitus.

The influence of online images on self-harm: A qualitative study of young people aged 16-24.

To date, research on the role of the Internet in self-harm has focused on young people's interaction via the medium of text, with limited consideration of the effect of images. This qualitative study explores how young people understand and use online images of self-harm. Semi-structured interviews were conducted with a community sample of 21 individuals aged 16-24 living in Wales, UK, with a previous history of self-harm. Interviewees reported the role of the Internet in normalising young people's self-harm. Images rather than textual interactions are the primary reason cited for using the Internet for self-harm purposes. Images invoke a physical reaction and inspire behavioural enactment, with Tumblr, which permits the sharing of images by anonymous individuals, being the preferred platform. Viewing online images serves a vital role in many young people's self-harm, as part of ritualistic practice. Online prevention and intervention need to attend to the importance of images.

A qualitative investigation of the role of the family in structuring young people's alcohol use.

BACKGROUND: Few qualitative studies have investigated young people's perspectives around influences on substance use. We aimed to examine young people's understandings, attitudes and experiences around alcohol, tobacco and cannabis use and factors influencing substance use behaviour. METHODS: Qualitative interview study involving 28 young people (13 males and 15 females) aged 18-20 years, recruited purposively on the basis of substance use, who were participating in the Avon Longitudinal Study of Parents and Children. Interviews were conducted at participants' homes or at local cafés. Audio data were transcribed verbatim, systematically coded and analysed inductively using a constant comparative approach. RESULTS: Parental attitudes and behaviours and the nature of communication emerged as critical factors structuring young people's alcohol use. Initiation of alcohol use was frequently mediated by parents early in adolescence, with the home recounted as a primary site of early drinking experiences. Later in adolescence, young people perceived a more permissive stance towards alcohol use, with broad acceptance of high levels of consumption and recognition of drinking as a cultural norm during adolescence. In contrast, young people reported a more prohibitive and discouraging stance from their parents towards tobacco and cannabis use, and the use of these substances appeared to be of greater parental concern. CONCLUSIONS: Interventions involving parents or guardians have a critical role to play in the prevention of harms arising from alcohol use during adolescence. However, such interventions are needed in conjunction with individual, school, community and environmental interventions to shift cultural norms across the population and to facilitate effective prevention.

Integrating qualitative research within a clinical trials unit: developing strategies and understanding their implementation in contexts.

BACKGROUND/AIMS: The value of using qualitative methods within clinical trials is widely recognised. How qualitative research is integrated within trials units to achieve this is less clear. This paper describes the process through which qualitative research has been integrated within Cardiff University's Centre for Trials Research (CTR) in Wales, UK. We highlight facilitators of, and challenges to, integration. METHODS: We held group discussions on the work of the Qualitative Research Group (QRG) within CTR. The content of these discussions, materials for a presentation in CTR, and documents relating to the development of the QRG were interpreted at a workshop attended by group members. Normalisation Process Theory (NPT) was used to structure analysis. A writing group prepared a document for input from members of CTR, forming the basis of this paper. RESULTS: Actions to integrate qualitative research comprised: its inclusion in Centre strategies; formation of a QRG with dedicated funding/roles; embedding of qualitative research within operating systems; capacity building/training; monitoring opportunities to include qualitative methods in studies; maximising the quality of qualitative research and developing methodological innovation. Facilitators of these actions included: the influence of the broader methodological landscape within trial/study design and its promotion of the value of qualitative research; and close physical proximity of CTR qualitative staff/students allowing sharing of methodological approaches. Introduction of innovative qualitative methods generated interest among other staff groups. Challenges included: pressure to under-resource qualitative components of research, preference for a statistical stance historically in some research areas and funding structures, and difficulties faced by qualitative researchers carving out individual academic profiles when working across trials/studies. CONCLUSIONS: Given that CTUs are pivotal to the design and conduct of RCTs and related study types across multiple disciplines, integrating qualitative research into trials units is crucial if its contribution is to be fully realised. We have made explicit one trials unit's experience of embedding qualitative research and present this to open dialogue on ways to operationalise and optimise qualitative research in trials. NPT provides a valuable framework with which to theorise these processes, including the importance of sense-making and legitimisation when introducing new practices within organisations.

"It's not just about the numbers": Inside the black box of nurses' professional judgement in nurse staffing systems in England and Wales: Insights from a qualitative cross-case comparative study.

BACKGROUND: Whether implicit or explicit, professional judgement is a central component of the many nurse staffing systems implemented in high-income countries to inform workforce planning and staff deployment. Whilst a substantial body of research has evaluated the technical and operational elements of nurse staffing systems, no studies have systematically examined the role of professional judgement and its contribution to decision-making. OBJECTIVE: To explore nurses' use of professional judgement in nurse staffing systems in England and Wales. METHODS: A cross-case comparative design centred on adult in-patient services in three University Health Boards in Wales and three National Health Service Trusts in England. Data generation was undertaken between January 2021 and March 2023 through stakeholder interviews, observations of staffing meetings, and analysis of documents and artefacts. Observations were undertaken in clinical areas but limited to three cases by COVID-19 restrictions. Analysis was informed by translational mobilisation theory. FINDINGS: Two kinds of professional judgement were deployed in the nurse staffing systems: the judgement of clinical nurses and the judgement of senior nurse managers. The research highlighted the reflexive relationship between professional judgement and data, and the circumstances in which organisations placed trust in people and when they placed trust in numbers. Nurses' professional judgement was central to the generation of data, its interpretation and contextualisation. Healthcare organisations relied on the professional judgements of clinical nurses and senior nurse managers in making operational decisions to mitigate risk, where real-world understanding of the status of the organisation was privileged over formal data. Professional judgement had attenuated authority for the purposes of workforce planning, where data was a master actor. Nurses expressed concerns that strategic decision-making prioritised safety and efficiency, and formal measurement systems did not capture important aspects of care quality or staff wellbeing, which made it difficult to articulate their professional judgement. CONCLUSIONS: The implementation of staffing systems is resource intensive. Given limited evidence on which to recommend any specific methodology, the priority for future research is to optimise existing systems. If nurses are to deploy their professional judgement to proactively influence the conditions for care, as well as responding to the challenges of risk mitigation, there is a need for robust systems of nursing measurement aligned with agreed standards of care and a vocabulary through which these judgements can be articulated. TWEETABLE ABSTRACT: Health systems depend on nurses' professional judgement for operational staffing decisions, but data is privileged over professional judgement for workforce planning.

Co-production of guidance and resources to implement principled participant information leaflets (PrinciPILs).

Background: The way information about potential benefits and harms of trial is presented within participant information leaflets (PILs) varies widely and may cause unnecessary 'nocebo' effects. The Medical Research Council (MRC) funded a project that developed seven principles to reduce this variation. However, guidance has not been produced to facilitate the implementation of the principles. Stakeholder involvement is recommended to optimise the way these principles are disseminated and explained. To co-produce recommendations for developing: (1) user-friendly guidance for users of the principles; and (2) resources that support the implementation of the principles. Methods: We held a co-production workshop with representation from the following professional groups: the Health Research Authority (HRA), research ethics committee members, and trial managers. Two rounds of discussions focused on generating recommendations for guidance and resources that support the implementation of the seven principles. Extensive low inference style ethnographic notes were taken, and the data were analysed thematically using deductive codes. The data was collected on October 14, 2022. Results: 25 participants attended a hybrid workshop. Participants recommended that both researchers designing PILs and research ethics committee members should use the principles, and that that they should be simple, mention both benefits and harms explicitly, include examples of visual representations, and provide the evidence base for the principles. Conclusions: We were able to co-produce recommendations for developing and implementing the seven principles within PILs. These recommendations can now be implemented to reduce unexplained variation in the way potential benefits and harms are shared within PILs.

Trial participants need to know about the potential benefits and harms of trial interventions to make an informed decision about whether to take part in a clinical trial. Yet the way they are told about these benefits and harms varies widely. We developed seven principles that can reduced this variability. We held a workshop with members of ethics committees and other stakeholders to develop the best way to implement the principles. 25 participants attended the workshop, and we were able to make useful recommendations that will improve the way trial participants are told about risks and benefits of trial treatments.

Patient reported outcomes and recruitment rates following the introduction of principled patient information leaflets (PrinciPILs): Protocol for a meta-analysis.

Background: The way potential benefits and harms of trial interventions are shared within patient information leaflets (PILs) varies widely and may cause unnecessary harms ("nocebo effects"). The aim of this meta-analysis will be to evaluate the influence on recruitment rates and early effects on patient reported adverse events of principled patient information leaflets (PrinciPILs) compared with standard PILs. Methods: Eligible studies will include those that report the effects on recruitment and patient reported adverse events of PrinciPILs compared to standard PILs. We will include in this meta-analysis all the standard PILs in studies within trials (SWATs) of PrinciPILs that were developed as part of the Medical Research Council (MRC) funded PrinciPIL project. By publishing this as a living meta-analysis, we will allow the meta-analysis to be updated with future SWATs of PrinciPILs. We will use the Cochrane Risk of Bias tool to evaluate the risk of bias for each outcome. We will report the total number of studies and participants analysed and the characteristics of included studies (including details of intervention, comparators, outcomes). For dichotomous data, we will calculate the risk difference and the risk ratio (RR) and 95% confidence intervals (CIs). For continuous outcomes we will use weighted mean differences with 95% CIs or standardized mean differences with 95% CIs. We will investigate heterogeneity by visually inspecting the forest plot and by considering the I 2 test result. We will assess the certainty warranted for each outcome using the Grading of Recommendations Assessment Development and Evaluation (GRADE). Ethics approval is not applicable since no original data will be collected. The results will be disseminated through peer-reviewed publication and conference presentations. Discussion: We will discuss the limitations of the meta-analysis including study risk of bias, inconsistency, heterogeneity, and imprecision. A general interpretation of the results and important implications will be provided.

People who take part in randomised trials need to understand the risks as well as the benefits of taking part. Most 'patient information leaflets' (PILs) that describe trial treatments include information about harms. Yet only some PILs contain information about potential benefits. This variation is confusing. Also, the over-emphasis on harms can cause "nocebo" effects, which are the harms caused by expecting something bad to happen. To solve these problems, we have developed seven principles that ensure that information about potential benefits and harms in PILs is balanced and consistent. We will now compare PILs that have been developed according to our principles (we call these 'PrinciPILs') with PILs that have not been developed with our principles. We will test whether PrinciPILs reduce nocebo effects and improve trial recruitment. Here we have described our plans to test the effect of PrinciPILs in a few trials.

Developing principles for sharing information about potential trial intervention benefits and harms with patients: report of a modified Delphi survey.

BACKGROUND: The way information about potential harms of trial intervention is shared within participant information leaflets (PILs) varies widely and can cause subjective 'nocebo' harms. This study aimed to develop principles to improve the composition of information about potential trial intervention benefits and harms within PILs so that variability and avoidable harms are reduced. METHODS: We conducted a two-round modified online Delphi survey, followed by a consensus meeting. For the first round of the survey, 27 statements were developed based on previous research and relevant guidance from the UK, the USA and the World Health Organization. Participants included members from each of the following stakeholder groups: patient and public representatives, research ethics committee members, industry representatives, medico-legal experts, psychologists and trial managers. Each participant was asked to rate their degree of agreement or disagreement with each statement on a 9-point Likert scale. In the second round, participants were invited to reappraise their ratings after reviewing the results of the first round. Finally, two members from each stakeholder group participated in a meeting to confirm those statements for which there was agreement. RESULTS: Two hundred and fifty participants completed round 1, and 201 participants completed round 2. In round 1, consensus was reached for 16 statements. In round 2, consensus was reached for an additional three statements. The consensus meeting confirmed the survey results and consolidated the statements. This process resulted in seven principles: (1) all potential harms of a given intervention should be listed, (2) all potential harms should be separated into serious and less serious, (3) it must be made explicit that not all potential harms are known, (4) all potential benefits should be listed, (5) all potential benefits and harms need to be compared with what would happen if the participant did not take part in the trial, (6) suitable visual representations should be added where appropriate and (7) information regarding potential benefits and harms should not be presented apart by one or more pages. CONCLUSIONS: Our modified Delphi process successfully generated seven principles that can and should be used to guide how information is conveyed to patients in information leaflets regarding potential trial benefits and harms.

Paediatric early warning systems: not a simple answer to a complex question.

Paediatric early warning systems (PEWS) to reduce in-hospital mortality have been a laudable endeavour. Evaluation of their impact has rarely examined the internal validity of the components of PEWS in achieving desired outcomes. We highlight the assumptions made regarding the mode of action of PEWS and, as PEWS become more commonplace, this paper asks whether we really understand their function, process and outcome.

The Number and Characteristics of Newspaper and Twitter Reports on Suicides and Road Traffic Deaths in Young People.

In the light of concern about the harmful effects of media reporting of suicides and a lack of comparative research, this study compares the number and characteristics of reports on suicides and road traffic accidents (RTAs) in young people (aged 11-18) in newspapers and Twitter during a 6-month period. Tweets about young people's suicides were more numerous than newspaper reports. Twitter and newspaper reports were more strongly correlated for suicides than for RTAs. Recent suicides were less likely to be reported in newspapers than recent deaths by RTA. Bullying-related suicides were especially newsworthy. Suicide prevention organizations should consider routinely monitoring social media reporting.

Optimising paediatric afferent component early warning systems: a hermeneutic systematic literature review and model development.

OBJECTIVE: To identify the core components of successful early warning systems for detecting and initiating action in response to clinical deterioration in paediatric inpatients. METHODS: A hermeneutic systematic literature review informed by translational mobilisation theory and normalisation process theory was used to synthesise 82 studies of paediatric and adult early warning systems and interventions to support the detection of clinical deterioration and escalation of care. This method, which is designed to develop understanding, enabled the development of a propositional model of an optimal afferent component early warning system. RESULTS: Detecting deterioration and initiating action in response to clinical deterioration in paediatric inpatients involves several challenges, and the potential failure points in early warning systems are well documented. Track and trigger tools (TTT) are commonly used and have value in supporting key mechanisms of action but depend on certain preconditions for successful integration into practice. Several supplementary interventions have been proposed to improve the effectiveness of early warning systems but there is limited evidence to recommend their wider use, due to the weight and quality of the evidence; the extent to which systems are conditioned by the local clinical context; and the need to attend to system component relationships, which do not work in isolation. While it was not possible to make empirical recommendations for practice, the review methodology generated theoretical inferences about the core components of an optimal system for early warning systems. These are presented as a propositional model conceptualised as three subsystems: detection, planning and action. CONCLUSIONS: There is a growing consensus of the need to think beyond TTTs in improving action to detect and respond to clinical deterioration. Clinical teams wishing to improve early warning systems can use the model to consider systematically the constellation of factors necessary to support detection, planning and action and consider how these arrangements can be implemented in their local context.

The Response in Twitter to an Assisted Suicide in a Television Soap Opera.

BACKGROUND: Concern has been expressed about the potentially contagious effect of television soap opera suicides and suicidal language in social media. AIMS: Twitter content was analyzed during the week in which a fictional assisted suicide was broadcast on a British television soap opera, "Coronation Street." METHOD: Tweets were collected if they contained language indicating possible suicidal intent or used the word suicide. The modified Thompson tau method was used to test for any differences in the volume of tweets in both categories on the day of screening. Content analysis broke down the use of the word suicide into six thematic categories. RESULTS: There was no evidence on the day of screening of an increase in tweets expressing possible suicidal intent but there was an increase in tweets containing the word suicide. Content analysis found the most common thematic category to be information or support, followed by the raising of moral issues in relation to suicide. CONCLUSION: It is possible that for certain high-profile media events Twitter may be used more as a civic reactive forum than as a medium for introspection or disclosure of distress.

Suicide prevention via the Internet: a descriptive review.

BACKGROUND: While concerns abound regarding the impact of the Internet on suicidal behaviors, its role as a medium for suicide prevention remains underexplored. AIMS: The study examines what is currently known about the operation and effectiveness of Internet programs for suicide and self-harm prevention that are run by professionals. METHOD: Systematic searches of scholarly databases and suicide-related academic journals yielded 15 studies that presented online prevention strategies. RESULTS: No professional programs with a sole focus on nonsuicidal self-harm were identified, thus all studies reviewed focused on suicide prevention. Studies were predominantly descriptive and summarized the nature of the strategy and the target audience. There was no formal evaluation of program effectiveness in preventing suicide. Studies either presented strategies that supported individuals at risk of suicide (n = 8), supported professionals working with those at risk (n = 6), or attempted to improve website quality (n = 1). CONCLUSION: Although the Internet increasingly serves as an important medium for suicidal individuals, and there is concern about websites that both promote and encourage suicidal activity, there is lack of published evidence about online prevention strategies. More attention is needed in the development and evaluation of such preventative approaches.
