Electrophysiological signatures of conceptual and lexical retrieval from semantic memory
Retrieval from semantic memory of conceptual and lexical information is essential for producing speech. It is unclear whether there are differences in the neural mechanisms of conceptual and lexical retrieval when spreading activation through semantic memory is initiated by verbal or nonverbal settings. The same twenty participants took part in two EEG experiments. The first experiment examined conceptual and lexical retrieval following nonverbal settings, whereas the second experiment was a replication of previous studies examining conceptual and lexical retrieval following verbal settings. Target pictures were presented after constraining and nonconstraining contexts. In the nonverbal settings, contexts were provided as two priming pictures (e.g., constraining: nest, feather; nonconstraining: anchor, lipstick; target picture: BIRD). In the verbal settings, contexts were provided as sentences (e.g., constraining: âThe farmer milked a...â; nonconstraining: âThe child drew a...â; target picture: COW). Target pictures were named faster following constraining contexts in both experiments, indicating that conceptual preparation starts before target picture onset in constraining conditions. In the verbal experiment, we replicated the alpha-beta power decreases in constraining relative to nonconstraining conditions before target picture onset. No such power decreases were found in the nonverbal experiment. Power decreases in constraining relative to nonconstraining conditions were significantly different between experiments. Our findings suggest that participants engage in conceptual preparation following verbal and nonverbal settings, albeit differently. The retrieval of a target word, initiated by verbal settings, is associated with alpha-beta power decreases. By contrast, broad conceptual preparation alone, prompted by nonverbal settings, does not seem enough to elicit alpha-beta power decreases. These findings have implications for theories of oscillations and semantic memory
Virtual Care and the Inverse Care Law: Implications for Policy, Practice, Research, Public and Patients.
Virtual care spread rapidly at the outbreak of the COVID-19 pandemic. Restricting in-person contact contributed to reducing the spread of infection and saved lives. However, the benefits of virtual care were not evenly distributed within and across social groups, and existing inequalities became exacerbated for those unable to fully access to, or benefit from virtual services. This "perspective" paper discusses the extent to which challenges in virtual care access and use in the context of COVID-19 follow the Inverse Care Law. The latter stipulates that the availability and quality of health care is inversely proportionate to the level of population health needs. We highlight the inequalities affecting some disadvantaged populations' access to, and use of public and private virtual care, and contrast this with a utopian vision of technology as the "solution to everything". In public and universal health systems, the Inverse Care Law may manifests itself in access issues, capacity, and/or lack of perceived benefit to use digital technologies, as well as in data poverty. For commercial "Direct-To-Consumer" services, all of the above may be encouraged via a consumerist (i.e., profit-oriented) approach, limited and episodic services, or the use of low direct cost platforms. With virtual care rapidly growing, we set out ways forward for policy, practice, and research to ensure virtual care benefits for everyone, which include: (1) pay more attention to "capabilities" supporting access and use of virtual care; (2) consider digital technologies as a basic human right that should be automatically taken into account, not only in health policies, but also in social policies; (3) take more seriously the impact of the digital economy on equity, notably through a greater state involvement in co-constructing "public health value" through innovation; and (4) reconsider the dominant digital innovation research paradigm to better recognize the contexts, factors, and conditions that influence access to and use of virtual care by different groups
Do good things come in small packages? Willingness to pay for pomegranate wine and bottle size effects
We evaluate the claim that bottle size formats signal quality changes, using a controlled laboratory experiment where we simultaneously auctioned two different sweet wines: a pomegranate wine and a grape wine. We varied on a between subjects basis the size of the bottle, from 500ml to 750ml, but kept the wine content of the bottle constant across bottle size formats. We also explored in a within subjects design the effect of expectations for the wines, blind tasting and information on willingness to pay. For the grape wine we find evidence consistent with diminishing marginal utility while for the pomegranate wine we find a premium for the smaller bottle size which is consistent with changes in perceived quality of the wine. We also find that information is adequate in offsetting the negative effect from the tasting treatment
Developing a typology of interventions to support doctorsâ mental health and wellbeing
Background:Â The problem of mental ill-health in doctors is complex, accentuated by the COVID-19 pandemic, and impacts on healthcare provision and broader organisational performance. There are many interventions to address the problem but currently no systematic way to categorise them, which makes it hard to describe and compare interventions. As a result, implementation tends to be unfocussed and fall short of the standards developed for implementing complex healthcare interventions. This study aims to develop: 1) a conceptual typology of workplace mental health and wellbeing interventions and 2) a mapping tool to apply the typology within research and practice.
Methods:Â Typology development was based on iterative cycles of analysis of published and in-practice interventions, incorporation of relevant theories and frameworks, and team and stakeholder group discussions.
Results:Â The newly developed typology and mapping tool enable interventions to be conceptualised and/or mapped into different categories, for example whether they are designed to be largely preventative (by either improving the workplace or increasing personal resources) or to resolve problems after they have arisen. Interventions may be mapped across more than one category to reflect the nuance and complexity in many mental health and wellbeing interventions. Mapping of interventions indicated that most publications have not clarified their underlying assumptions about what causes outcomes or the theoretical basis for the intervention.
Conclusion:Â The conceptual typology and mapping tool aims to raise the quality of future research and promote clear thinking about the nature and purpose of interventions, In doing so it aims to support future research and practice in planning interventions to improve the mental health and wellbeing of doctors
Optimising feedback for early career professionals: a scoping review and new framework
Context
Metaâanalyses have shown that feedback can be a powerful intervention to increase learning and performance but there is significant variability in impact. New trials are adding little to the question of whether feedback interventions are effective, so the focus now is how to optimise the effect. Early career professionals (ECPs) in busy work environments are a particularly important target group. This literature review aimed to synthesise information to support the optimal design of feedback interventions for ECPs.
Methods
We undertook a scoping literature review, using search terms such as âfeedbackâ and âeffectivenessâ in MEDLINE, MEDLINEâInâProcess, PsycINFO, CINAHL, Education Research Complete, Education Resources Information Center, the Cochrane Database of Systematic Reviews, the Social Sciences Citation Index and Applied Social Sciences Index and Abstracts, to identify empirical studies describing feedback interventions in busy workplaces published in English since 1990. We applied inclusion criteria to identify studies for the mapping stage and extracted key data to inform the next stage. We then selected a subset of papers for the framework development stage, which were subjected to a thematic synthesis by three authors, leading to a new feedback framework and a modified version of feedback intervention theory specifically for ECPs.
Results
A total of 80 studies were included in the mapping stage, with roughly equal studies from hospital settings and school classrooms, and 17 papers were included in the framework development stage. The feedback framework comprised three main categories (audit, feedback and goal setting) and 22 subcategories. The review highlighted the limited empirical research focusing solely on feedback for ECPs, which was surprising given the particular nuances in feedback for ECPs identified through this study.
Conclusions
We offer the feedback framework to optimise the design of future feedback interventions for early career professionals and encourage future feedback research to move away from generic models and tailor work to specific target audiences
Implementation and delivery of group consultations for young people with diabetes in socioeconomically deprived, ethnically diverse settings
BACKGROUND: Young people with diabetes experience poor clinical and psychosocial outcomes, and consider the health service ill-equipped in meeting their needs. Improvements, including alternative consulting approaches, are required to improve care quality and patient engagement. We examined how group-based, outpatient diabetes consultations might be delivered to support young people (16-25 years old) in socio-economically deprived, ethnically diverse settings. METHODS: This multi-method, comparative study recruited a total of 135 young people with diabetes across two implementation and two comparison sites (2017-2019). Informed by a 'researcher-in-residence' approach and complexity theory, we used a combination of methods: (a) 31 qualitative interviews with young people and staff and ethnographic observation in group and individual clinics, (b) quantitative analysis of sociodemographic, clinical, service use, and patient enablement data, and (c) micro-costing analysis. RESULTS: Implementation sites delivered 29 group consultations in total. Overall mean attendance per session was low, but a core group of young people attended repeatedly. They reported feeling better understood and supported, gaining new learning from peers and clinicians, and being better prepared to normalise diabetes self-care. Yet, there were also instances where peer comparison proved difficult to manage. Group consultations challenged deeply embedded ways of thinking about care provision and required staff to work flexibly to achieve local tailoring, sustain continuity, and safely manage complex interdependencies with other care processes. Set-up and delivery were time-consuming and required in-depth clinical and relational knowledge of patients. Facilitation by an experienced youth worker was instrumental. There was indication that economic value could derive from preventing at least one unscheduled consultation annually. CONCLUSIONS: Group consulting can provide added value when tailored to meet local needs rather than following standardised approaches. This study illustrates the importance of adaptive capability and self-organisation when integrating new models of care, with young people as active partners in shaping service provision.

Why do GPs rarely do video consultations? qualitative study in UK general practice.
BACKGROUND: Fewer than 1% of UK general practice consultations occur by video. AIM: To explain why video consultations are not more widely used in general practice. DESIGN AND SETTING: Analysis of a sub-sample of data from three mixed-method case studies of remote consultation services in various UK settings from 2019-2021. METHOD: The dataset included interviews and focus groups with 121 participants from primary care (33 patients, 55 GPs, 11 other clinicians, nine managers, four support staff, four national policymakers, five technology industry). Data were transcribed, coded thematically, and then analysed using the Planning and Evaluating Remote Consultation Services (PERCS) framework. RESULTS: With few exceptions, video consultations were either never adopted or soon abandoned in general practice despite a strong policy push, short-term removal of regulatory and financial barriers, and advances in functionality, dependability, and usability of video technologies (though some products remained 'fiddly' and unreliable). The relative advantage of video was perceived as minimal for most of the caseload of general practice, since many presenting problems could be sorted adequately and safely by telephone and in-person assessment was considered necessary for the remainder. Some patients found video appointments convenient, appropriate, and reassuring but others found a therapeutic presence was only achieved in person. Video sometimes added value for out-of-hours and nursing home consultations and statutory functions (for example, death certification). CONCLUSION: Efforts to introduce video consultations in general practice should focus on situations where this modality has a clear relative advantage (for example, strong patient or clinician preference, remote localities, out-of-hours services, nursing homes)
Interventions to improve antimicrobial prescribing of doctors in training (IMPACT): a realist review
Background
Interventions to improve the antimicrobial prescribing practices of doctors have been implemented widely to curtail the emergence and spread of antimicrobial resistance, but have been met with varying levels of success.
Objectives
This study aimed to generate an in-depth understanding of how antimicrobial prescribing interventions âworkâ (or do not work) for doctors in training by taking into account the wider context in which prescribing decisions are enacted.
Design
The review followed a realist approach to evidence synthesis, which uses an interpretive, theory-driven analysis of qualitative, quantitative and mixed-methods data from relevant studies.
Setting
Primary and secondary care.
Participants
Not applicable.
Interventions
Studies related to antimicrobial prescribing for doctors in training.
Main outcome measures
Not applicable.
Data sources
EMBASE (via Ovid), MEDLINE (via Ovid), MEDLINE In-Process and Other Non-Indexed Citations (via Ovid), PsycINFO (via Ovid), Web of Science core collection limited to Science Citation Index Expanded (SCIE) and Conference Proceedings Citation Index â Science (CPCI-S) (via Thomson Reuters), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, the Health Technology Assessment (HTA) database (all via The Cochrane Library), Applied Social Sciences Index and Abstracts (ASSIA) (via ProQuest), Google Scholar (Google Inc., Mountain View, CA, USA) and expert recommendations.
Review methods
Clearly bounded searches of electronic databases were supplemented by citation tracking and grey literature. Following quality standards for realist reviews, the retrieved articles were systematically screened and iteratively analysed to develop theoretically driven explanations. A programme theory was produced with input from a stakeholder group consisting of practitioners and patient representatives.
Results
A total of 131 articles were included. The overarching programme theory developed from the analysis of these articles explains how and why doctors in training decide to passively comply with or actively follow (1) seniorsâ prescribing habits, (2) the way seniors take into account prescribing aids and seek the views of other health professionals and (3) the way seniors negotiate patient expectations. The programme theory also explains what drives willingness or reluctance to ask questions about antimicrobial prescribing or to challenge the decisions made by seniors. The review outlines how these outcomes result from complex inter-relationships between the contexts of practice doctors in training are embedded in (hierarchical relationships, powerful prescribing norms, unclear roles and responsibilities, implicit expectations about knowledge levels and application in practice) and the mechanisms triggered in these contexts (fear of criticism and individual responsibility, reputation management, position in the clinical team and appearing competent). Drawing on these findings, we set out explicit recommendations for optimal tailoring, design and implementation of antimicrobial prescribing interventions targeted at doctors in training.
Limitations
Most articles included in the review discussed hospital-based, rather than primary, care. In cases when few data were available to fully capture all the nuances between context, mechanisms and outcomes, we have been explicit about the strength of our arguments.
Conclusions
This review contributes to our understanding of how antimicrobial prescribing interventions for doctors in training can be better embedded in the hierarchical and interprofessional dynamics of different health-care settings.
Future work
More work is required to understand how interprofessional support for doctors in training can contribute to appropriate prescribing in the context of hierarchical dynamics
