Association between breakfast skipping and blood levels of lead and cadmium in children and adolescents aged 6-17 years: Results from the national health and nutrition examination survey 2013-2018.

INTRODUCTION: Previous research suggests that fasting increases lead absorption in the gastrointestinal tract, and that regularly eating meals may reduce blood lead. However, there is insufficient evidence linking breakfast status and blood-metal levels in children. We assessed the cross-sectional association between breakfast consumption status and children and adolescent's blood levels of lead and cadmium. We also explored blood hemoglobin, serum ferritin, and age group as potential effect modifiers of these associations. METHODS: This analysis included children and adolescents aged 6-17 years who participated in the National Health and Nutrition Examination Survey (NHANES) cycles 2013-2018 with complete data on breakfast consumption status (consumers vs. skippers), blood metals, and covariates (N=3722). Blood metal variables were log-transformed. Crude and covariate-adjusted, survey-weighted linear regression models were conducted for each blood metal outcome. Potential effect modification was explored using stratification. RESULTS: Overall fewer participants reported skipping breakfast (n=719) than eating breakfast (n=3003). Mean (SE) concentrations of blood lead and cadmium (µg/L) were 0.63 (0.01) µg/dL and 0.13 (0.00) µg/L, respectively. Children and adolescents who skipped breakfast were more likely to be female (51.2%), older (mean 12.2 years, SE = 0.1), have a higher body mass index (mean 22.8 kg/m2, SE = 0.2), and a lower income-poverty ratio (mean 1.7, SE = 0.1) than breakfast consumers. No associations between breakfast consumption and any of the blood metals were found. When stratified by age (≤ 10, 11-13, and 14-17 years), children aged 11-13 years who consumed breakfast had lower log-transformed blood lead levels [ß = -0.14 µg/L; 95% CI: (-0.25, -0.03)] compared to children of the same age who skipped breakfast. CONCLUSION: Children 11-13 years-old who were breakfast consumers had lower blood lead levels compared to children of the same age who skipped breakfast. Our results support that encouraging breakfast consumption among school-age children may contribute to lower blood lead levels.

Effectiveness of the Spot tm Vision Screener With Variations in Ocular Pigments.

PURPOSE: To evaluate Spot in detecting American Association for Pediatric Ophthalmology and Strabismus (AAPOS) Amblyopia risk factors (ARF) and for ARF myopia and hyperopia with variations in ocular pigments. DESIGN: Diagnostic screening test evaluation. METHODS: Study population: Children presented for a complete eye examination in pediatric clinic. The study population included 1040 participants, of whom 273 had darkly pigmented eyes, 303 were medium pigmented, and 464 were light pigmented. INTERVENTION: Children were screened with the Spot vision screener before the complete eye examination. A pediatric ophthalmologist then completed an eye examination, including cycloplegic refraction. The pediatric ophthalmologist was blinded to the result of the Spot vision screener. MAIN OUTCOME: The association between Spot screening recommendation and meeting one or more ARF/ARF + Amblyopia criterion, Spot measured spherical equivalent, and ARF myopia and hyperopia detection. RESULTS: The area under the receiver operative characteristic curve (AUC) for myopia was excellent for all. The AUC for hyperopia was good (darker-pigmented: 0.92, medium-pigmented: 0.81, and lighter-pigmented: 0.86 eyes). The Spot was most sensitive for ARF myopia (lighter-pigmented: 0.78, medium-pigmented: 0.52, darker-pigmented: 0.49). The reverse was found for hyperopia; however, sensitivity was relatively poor. The Spot was found most sensitive for hyperopia in the darker-pigment group (0.46), 0.27 for medium-pigment, and 0.23 for the lighter-pigment cohort. CONCLUSIONS: While the Spot was confirmed as a sensitive screening test with good specificity in our large cohort, the sensitivity of the Spot in detecting AAPOS guidelines for myopia and hyperopia differed with variations in skin pigment. Our results support the consideration of ethnic and racial diversity in future advances in photorefractor technology.

From corners to community: exploring medical students' sense of belonging through co-creation in clinical learning.

BACKGROUND: Belonging is critical for the development and wellbeing of medical students. Belonging, particularly within a 'relational being' paradigm, presents a significant challenge for students, especially within clinical learning environments. Co-creation is a learning relationship in which students are actively involved in the education process. It is inherently relational and promotes belonging within higher education environments. Little is known about utilising co-creation in the curriculum, within medical education. The aim of this study was to explore medical students' experience of co-creation of learning resources within the clinical learning environment. METHODS: Following ethical approval, medical students were invited to become co-creators of a learning bulletin resource, within the paediatric acute receiving unit, at a paediatric teaching hospital. Interpretative phenomenological analysis (IPA) was used to enable an in-depth exploration of how medical students experienced co-creation within the clinical learning environment. Medical students participated in semi-structured interviews about their experience, which were transcribed verbatim and analysed using IPA. The analysis integrated individual lived experiences into an analytic summary. RESULTS: Nine medical students participated. Three group experiential themes were identified: identity maturation; learning community and workplace integration. The support found within this co-created learning community, along with maturation of their identity, allowed the participants to experience a challenge to their existing worldview. This shift in perspective resulted in them responding and behaving in the workplace in new ways, which enabled them to belong as themselves in the clinical learning environment. These findings were situated within the developmental concept of self-authorship, as well as contributing to a new understanding of how co-creation promoted social integration. CONCLUSIONS: Co-creation enabled students to learn in a meaningful way. The relational power of co-creation, can be harnessed to deliver participatory learning experiences, within our increasingly complex healthcare environment, to support the learning, development and integration of doctors of the future.

Learning ratio performance on a brief visual learning and memory test moderates cognitive training gains in Double Decision task in healthy older adults.

Cognitive training using a visual speed-of-processing task, called the Useful Field of View (UFOV) task, reduced dementia risk and reduced decline in activities of daily living at a 10-year follow-up in older adults. However, there was variability in the achievement of cognitive gains after cognitive training across studies, suggesting moderating factors. Learning trials of visual and verbal learning tasks recruit similar cognitive abilities and have overlapping neural correlates with speed-of-processing/working memory tasks and therefore could serve as potential moderators of cognitive training gains. This study explored the association between the Hopkins Verbal Learning Test-Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) learning with a commercial UFOV task called Double Decision. Through a secondary analysis of a clinical trial, we assessed the moderation of HVLT-R and BVMT-R learning on Double Decision improvement after a 3-month speed-of-processing/attention and working memory cognitive training intervention in a sample of 75 cognitively healthy older adults. Multiple linear regressions showed that better baseline Double Decision performance was significantly associated with better BVMT-R learning (ß = - .303). This association was not significant for HVLT-R learning (ß = - .142). Moderation analysis showed that those with poorer BVMT-R learning improved the most on the Double Decision task after cognitive training. This suggests that healthy older adults who perform below expectations on cognitive tasks related to the training task may show the greatest training gains. Future cognitive training research studying visual speed-of-processing interventions should account for differing levels of visuospatial learning at baseline, as this could impact the magnitude of training outcomes and efficacy of the intervention.

Exploring the role of palliative care occupational therapists in supporting compassionate communities in end-of-life care.

INTRODUCTION: The compassionate communities' movement is a public health approach to end-of-life care that emphasises the integral role of communities in supporting and caring for dying persons and their informal carers. Although occupational therapists have well-established roles in palliative care teams, little is known about their potential in assisting in the formation and maintenance of compassionate communities. METHOD: Data were gathered via semi-structured interviews with nine Australian occupational therapists with experience in specialist palliative care. Interview questions were based around the British Columbia Compassionate Community Ideal framework. Key themes were derived through qualitative descriptive analysis, blending deductive, and inductive reasoning. FINDINGS: Interviewees indicated that occupational therapists have a role in supporting compassionate communities that centres on the facilitation of networks and connections between palliative care professionals and in the promotion of informal care networks. The importance of education and awareness raising were also discussed as valuable to the development of community capacity. It was also suggested that occupational therapists have important skills to support dying persons and their caregivers to remain engaged and safe in their homes and communities, in a meaningful and sustainable way. However, many interviewees maintained a profession-centric view on control within compassionate communities, as opposed to approaches that are community led. CONCLUSION: Findings offer early insights into the promise and potential of occupational therapists in supporting the compassionate communities' movement. However, education regarding the ethos of the compassionate communities' movement so as to facilitate a shift away from professionally oriented modes of practice may be needed to maximise success.

Application of a Web-based Tool for Quantitative Bias Analysis: The Example of Misclassification Due to Self-reported Body Mass Index.

BACKGROUND: We describe the use of Apisensr, a web-based application that can be used to implement quantitative bias analysis for misclassification, selection bias, and unmeasured confounding. We apply Apisensr using an example of exposure misclassification bias due to use of self-reported body mass index (BMI) to define obesity status in an analysis of the relationship between obesity and diabetes. METHODS: We used publicly available data from the National Health and Nutrition Examination Survey. The analysis consisted of: (1) estimating bias parameter values (sensitivity, specificity, negative predictive value, and positive predictive value) for self-reported obesity by sex, age, and race-ethnicity compared to obesity defined by measured BMI, and (2) using Apisensr to adjust for exposure misclassification. RESULTS: The discrepancy between self-reported and measured obesity varied by demographic group (sensitivity range: 75%-89%; specificity range: 91%-99%). Using Apisensr for quantitative bias analysis, there was a clear pattern in the results: the relationship between obesity and diabetes was underestimated using self-report in all age, sex, and race-ethnicity categories compared to measured obesity. For example, in non-Hispanic White men aged 40-59 years, prevalence odds ratios for diabetes were 3.06 (95% confidence inerval = 1.78, 5.30) using self-reported BMI and 4.11 (95% confidence interval = 2.56, 6.75) after bias analysis adjusting for misclassification. CONCLUSION: Apisensr is an easy-to-use, web-based Shiny app designed to facilitate quantitative bias analysis. Our results also provide estimates of bias parameter values that can be used by other researchers interested in examining obesity defined by self-reported BMI.

Safety on the ground: using critical incident technique to explore the factors influencing medical registrars' provision of safe care.

BACKGROUND: Avoidable patient harm in hospitals is common, and doctors in training can provide underused but crucial insights into the influencers of patient safety as those working 'on the ground' within the system. This study aimed to explore the factors that influence safe care from the perspective of medical registrars, to identify targets for safety-related improvements. METHODS: This study used enhanced critical incident technique (CIT), a qualitative methodology that results in a focused understanding of significant factors influencing an activity, to identify practical solutions. We interviewed 12 out of 17 consenting medical registrars in Scotland, asking them to recount their observations during clinical experiences where something happened that positively or negatively impacted on patient safety. Data were analysed manually using a modified content analysis with credibility checks as per enhanced CIT, with data exhaustiveness reached after six registrars. RESULTS: A total of 221 critical incidents impacting patient safety were identified. These were inductively placed into 24 categories within 4 overarching categories: Individual skills, encompassing individual behavioural and technical skills; Collaboration, regarding how communication, trust, support and flexibility shape interprofessional collaboration; Organisation, concerning organisational systems and staffing and Training environment, relating to culture, civility, having a voice and learning at work. Practical targets for safety-related interventions were identified, such as clear policies for patient care ownership or educational interventions to foster civility. CONCLUSIONS: This study provides a rigorous and focused understanding of the factors influencing patient safety in hospitals, using the 'insider' perspective of the medical registrar. Safety goes beyond the individual and is reliant on safe system design, interprofessional collaboration and a culture of support, learning and respect. Organisations should also promote flexibility within clinical practice when patient needs do not conform to standardised care pathways. We suggest targeted interventions within educational and organisational priorities to improve safety in hospitals.

Place of Death for Adults Receiving Specialist Palliative Care in Their Last 3 Months of Life: Factors Associated With Preferred Place, Actual Place, and Place of Death Congruence.

Objectives: Congruence between the preferred and actual place of death is recognised as an important quality indicator in end-of-life care. However, there may be complexities about preferences that are ignored in summary congruence measures. This article examined factors associated with preferred place of death, actual place of death, and congruence for a sample of patients who had received specialist palliative care in the last three months of life in Ireland. Methods: This article analysed merged data from two previously published mortality follow-back surveys: Economic Evaluation of Palliative Care in Ireland (EEPCI); Irish component of International Access, Rights and Empowerment (IARE I). Logistic regression models examined factors associated with (a) preferences for home death versus institutional setting, (b) home death versus hospital death, and (c) congruent versus non-congruent death. Setting: Four regions with differing levels of specialist palliative care development in Ireland. Participants: Mean age 77, 50% female/male, 19% living alone, 64% main diagnosis cancer. Data collected 2011-2015, regression model sample sizes: n = 342-351. Results: Congruence between preferred and actual place of death in the raw merged dataset was 51%. Patients living alone were significantly less likely to prefer home versus institution death (OR 0.389, 95%CI 0.157-0.961), less likely to die at home (OR 0.383, 95%CI 0.274-0.536), but had no significant association with congruence. Conclusions: The findings highlight the value in examining place of death preferences as well as congruence, because preferences may be influenced by what is feasible rather than what patients would like. The analyses also underline the importance of well-resourced community-based supports, including homecare, facilitating hospital discharge, and management of complex (eg, non-cancer) conditions, to facilitate patients to die in their preferred place.

The impact of a tDCS and cognitive training intervention on task-based functional connectivity.

Declines in several cognitive domains, most notably processing speed, occur in non-pathological aging. Given the exponential growth of the older adult population, declines in cognition serve as a significant public health issue that must be addressed. Promising studies have shown that cognitive training in older adults, particularly using the useful field of view (UFOV) paradigm, can improve cognition with moderate to large effect sizes. Additionally, meta-analyses have found that transcranial direct current stimulation (tDCS), a non-invasive form of brain stimulation, can improve cognition in attention/processing speed and working memory. However, only a handful of studies have looked at concomitant tDCS and cognitive training, usually with short interventions and small sample sizes. The current study assessed the effect of a tDCS (active versus sham) and a 3-month cognitive training intervention on task-based functional connectivity during completion of the UFOV task in a large older adult sample (N = 153). We found significant increased functional connectivity between the left and right pars triangularis (the ROIs closest to the electrodes) following active, but not sham tDCS. Additionally, we see trending behavioral improvements associated with these functional connectivity changes in the active tDCS group, but not sham. Collectively, these findings suggest that tDCS and cognitive training can be an effective modulator of task-based functional connectivity above and beyond a cognitive training intervention alone.

Do Concerns About Police Reporting Vary by Assault Characteristics? Understanding the Nonreporting Decisions of Sexual Assault Victims Who Utilize Alternative Reporting Options.

INTRODUCTION: Forensic nurses routinely provide services to sexual assault victims who are uncertain about reporting their assault to police. The purpose of this study was to determine whether assault characteristics are related to the concerns about police reporting expressed by sexual assault victims who have forensic evidence collected but do not report their assault to police at that time. METHODS: We analyzed medical records of patients who received services at a hospital-based forensic nursing program between 2010 and 2021. Records were included if a sexual assault evidence kit was collected, the patient declined to report the assault to police, and the patient completed a nonreport sexual assault evidence kit supplement form that included a question asking why they chose not to report the assault (N = 296). We qualitatively analyzed patients' reasons for not reporting the assault and then used two-variable case-ordered matrices and chi-square analyses to explore relationships between reasons for not reporting and assault characteristics. RESULTS: Identified reasons for not reporting included lacking information about the assault, fear of harm/retaliation, and self-blame/minimization. Physical force, drug/alcohol consumption, and victim-offender relationship were related to patients referencing lacking information and fearing harm/retaliation as reasons for not reporting, but not related to the frequency of patients referencing self-blame/minimization. IMPLICATIONS: Results indicate that assault characteristics are related to reasons for not reporting at the time of the medical forensic examination. Being aware of these relationships may help forensic nurses provide patient-centered services and anticipatory guidance.

Rolling the evolutionary dice: Neisseria commensals as proxies for elucidating the underpinnings of antibiotic resistance mechanisms and evolution in human pathogens.

Species within the genus Neisseria are adept at sharing adaptive allelic variation, with commensal species repeatedly transferring resistance to their pathogenic relative Neisseria gonorrhoeae. However, resistance in commensals is infrequently characterized, limiting our ability to predict novel and potentially transferable resistance mechanisms that ultimately may become important clinically. Unique evolutionary starting places of each Neisseria species will have distinct genomic backgrounds, which may ultimately control the fate of evolving populations in response to selection as epistatic and additive interactions coerce lineages along divergent evolutionary trajectories. Alternatively, similar genetic content present across species due to shared ancestry may constrain existing adaptive solutions. Thus, identifying the paths to resistance across commensals may aid in characterizing the Neisseria resistome-or the reservoir of alleles within the genus as well as its depth. Here, we use in vitro evolution of four commensal species to investigate the potential and repeatability of resistance evolution to two antimicrobials, the macrolide azithromycin and the ß-lactam penicillin. After 20 days of selection, commensals evolved resistance to penicillin and azithromycin in 11/16 and 12/16 cases, respectively. Almost all cases of resistance emergence converged on mutations within ribosomal components or the mtrRCDE efflux pump for azithromycin-based selection and mtrRCDE, penA, and rpoB for penicillin selection, thus supporting constrained adaptive solutions despite divergent evolutionary starting points across the genus for these particular drugs. Though drug-selected loci were limited, we do identify novel resistance-imparting mutations. Continuing to explore paths to resistance across different experimental conditions and genomic backgrounds, which could shunt evolution down alternative evolutionary trajectories, will ultimately flesh out the full Neisseria resistome.IMPORTANCENeisseria gonorrhoeae is a global threat to public health due to its rapid acquisition of antibiotic resistance to all first-line treatments. Recent work has documented that alleles acquired from close commensal relatives have played a large role in the emergence of resistance to macrolides and beta-lactams within gonococcal populations. However, commensals have been relatively underexplored for the resistance genotypes they may harbor. This leaves a gap in our understanding of resistance that could be rapidly acquired by the gonococcus through a known highway of horizontal gene exchange. Here, we characterize resistance mechanisms that can emerge in commensal Neisseria populations via in vitro selection to multiple antimicrobials and begin to define the number of paths to resistance. This study, and other similar works, may ultimately aid both surveillance efforts and clinical diagnostic development by nominating novel and conserved resistance mechanisms that may be at risk of rapid dissemination to pathogen populations.

Systematic review of clinical debriefing tools: attributes and evidence for use.

BACKGROUND AND OBJECTIVES: Clinical debriefing (CD) following a clinical event has been found to confer benefits for staff and has potential to improve patient outcomes. Use of a structured tool to facilitate CD may provide a more standardised approach and help overcome barriers to CD; however, we presently know little about the tools available. This systematic review aimed to identify tools for CD in order to explore their attributes and evidence for use. METHODS: A systematic review was conducted in line with PRISMA standards. Five databases were searched. Data were extracted using an electronic form and analysed using critical qualitative synthesis. This was guided by two frameworks: the '5 Es' (defining attributes of CD: educated/experienced facilitator, environment, education, evaluation and emotions) and the modified Kirkpatrick's levels. Tool utility was determined by a scoring system based on these frameworks. RESULTS: Twenty-one studies were included in the systematic review. All the tools were designed for use in an acute care setting. Criteria for debriefing were related to major or adverse clinical events or on staff request. Most tools contained guidance on facilitator role, physical environment and made suggestions relating to psychological safety. All tools addressed points for education and evaluation, although few described a process for implementing change. Staff emotions were variably addressed. Many tools reported evidence for use; however, this was generally low-level, with only one tool demonstrating improved patient outcomes. CONCLUSION: Recommendations for practice based on the findings are made. Future research should aim to further examine outcomes evidence of these tools in order to optimise the potential of CD tools for individuals, teams, healthcare systems and patients.

Real-world Evidence Comparing Tofacitinib and Vedolizumab in Anti-TNF-experienced Patients With Ulcerative Colitis.

BACKGROUND: Antitumor necrosis factor (anti-TNF) inhibitors are first-line treatment among patients with ulcerative colitis (UC). With time, patients tend to lose response or become intolerant, necessitating switching to small cell biologics such as tofacitinib or vedolizumab. In this real-world study of a large, geographically diverse US population of TNF-experienced patients with UC, we evaluated the effectiveness and safety of newly initiating treatment with tofacitinib vs vedolizumab. METHODS: We conducted a cohort study using secondary data from a large US insurer (Anthem, Inc.). Our cohort included patients with UC newly initiating treatment with tofacitinib or vedolizumab. Patients were required to have evidence of treatment with anti-TNF inhibitors in the 6 months prior to cohort entry. The primary outcome was treatment persistence >52 weeks. Additionally, we evaluated the following secondary outcomes as additional measures of effectiveness and safety: (1) all-cause hospitalization; (2) total abdominal colectomy; (3) hospitalization for infection; (4) hospitalization for malignancy; (5) hospitalization for cardiac events; and (6) hospitalization for thromboembolic events. We used fine stratification by propensity scores to control for confounding by demographics, clinical factors, and treatment history at baseline. RESULTS: Our primary cohort included 168 new users of tofacitinib and 568 new users of vedolizumab. Tofacitinib was associated with lower treatment persistence (adjusted risked ratio, 0.77; 95% CI, 0.60 -0.99). Differences in secondary measures of effectiveness or safety between tofacitinib initiators vs vedolizumab initiators were not statistically significant (all-cause hospitalization, adjusted hazard ratio, 1.23; 95% CI, 0.83-1.84; total abdominal colectomy, adjusted HR, 1.79; 95% CI, 0.93-3.44;and hospitalization for any infection, adjusted HR, 1.94; 95% CI, 0.83-4.52). DISCUSSION: Ulcerative colitis patients with prior anti-TNF experience initiating tofacitinib demonstrated lower treatment persistence compared with those initiating vedolizumab. This finding is in contrast to other recent studies suggesting superior effectiveness of tofacitinib. Ultimately, head-to-head randomized, controlled trials that focus on directly measured end points may be needed to best inform clinical practice.

Anti-TNF-experienced patients with UC initiating vedolizumab demonstrated higher treatment persistence compared with those initiating tofacitinib in this real-world evaluation of comparative effectiveness. Ultimately, head-to-head randomized trials that focus on directly measured end points are needed to best inform clinical practice.

Elements of exercise prescription in Randomised controlled trials of musculoskeletal rehabilitation in a one-on-one setting. A scoping review.

BACKGROUND: Randomised controlled trials (RCTs) are used by clinicians to inform evidence-based practice including when providing exercise programs. They should sufficiently report exercise interventions to permit accurate replication and incorporation into clinical practice. OBJECTIVES: The aim of this scoping review was to describe the elements used within the exercise prescription process for musculoskeletal rehabilitation in a one-on-one setting reported in RCTs including their methods and prescription in intervention or control groups. METHODS: The databases CINHAL, COCHRANE, EMBASE, MEDLINE and PUBMED were searched using a predefined strategy. Articles were reviewed according to detailed inclusion/exclusion criteria which included whether they were RCTs prescribing exercises for musculoskeletal rehabilitation in a one-on-one setting published within the last 5 years. For studies retained following screening, data extracted included year of publication, musculoskeletal condition and interventions studied. A pre-determined checklist ascertained the elements of the exercise prescription process reported in each study. Data obtained were analysed descriptively and summarised. RESULTS: After screening, 153 studies were retained for data extraction. The two most reported items included 'specific dosages provided' (75%, n = 115), and 'observe the patient performing the exercises' (71%. n = 108). Over half of studies reported basing their exercise intervention on existing evidence-based protocols (61%, n = 93). Elements considering biomechanical principles were the most 'unclear'. Most of the checklist items received an 'unclear' score due to inadequate descriptions of interventions. CONCLUSION: Many RCTs under report the development and prescription of exercise interventions, limiting replication of findings in clinical practice. A comprehensive framework is needed to ensure exercise prescription is adequately reported.

The Rubik's cube of doing and being: Factors influencing professional identity transition to the medical registrar.

BACKGROUND: Professional identity transitions, such as the transition to medical registrar, are challenging. How minoritised identities influence transitions during medical training requires further study. This study aimed to explore the factors influencing the transition to the medical registrar in Scotland to guide support during training. METHODS: Interviews exploring this transition with internal medicine trainees were audio recorded, transcribed verbatim and double-coded using template analysis. We applied an initial coding template informed by multiple and multidimensional transition theory of individual, interpersonal, systemic and macro-level factors. Using a critical theory lens, a further template analysis specifically sought to understand how trainees' social identities interacted with the various levels. FINDINGS: Nineteen IM trainees were interviewed between January 2021 and February 2022. Influential factors reflected a parallel process of competence (doing) and identity (being) development. The interaction of social identities, such as gender (being a woman) and country of origin (being an international medical graduate), occurred across levels. This can be conceptualised as a Rubik's cube with the interplay between doing and being from an individual to a macro level with trainees' social identities interacting at all levels. CONCLUSION: The transition to the medical registrar is multifaceted; with a challenging balance between support and independence in providing opportunities to perform (doing) whilst identity develops (being). Identity transitions involve multiple Rubik's-cube-like rotations between the facets of 'doing' and 'being,' until these align. Taking heed of influential factors and the interaction of minoritised social identities could guide a trainee-centred and smoother transition.

Unlocking the learning potential of simulation-based education.

Simulation is ubiquitous in the training of hospital-based doctors worldwide, often focusing on an individual level in traditional 'skills and drills'-based training. However, there has been an expansion in the use of simulation in healthcare practice and training. Simulation is being adopted into many disciplines that traditionally have not used this form of experiential learning. Moreover, simulation is increasingly being harnessed to enhance team and organisational learning in hospital-based practice. This article shares some insights into simulation-based education and makes the 'familiar unfamiliar' about this important method of learning. The aim is to broaden readers' outlook about what simulation has to offer beyond the classic notion of skills and drills-based training.

Snakes and ladders: An integrative literature review of refugee doctors' workforce integration needs.

INTRODUCTION: Healthcare systems worldwide are facing a workforce crisis; meanwhile, refugee doctors throughout the world face difficulties in accessing work. The aims of this review were to explore the integration needs of refugee doctors into host healthcare systems from the refugee perspective, synthesise the literature to construct a theory of refugee doctor integration needs and explore how these needs are met or challenged on the pathway to full integration. METHODS: In this integrative literature review, 11 databases and eight grey literature sources were searched by combining terms for refugee doctor and social integration and limiting to research published in or after 2003. Data were extracted, and quality scoring was completed independently by two researchers. This study utilised template analysis to perform a qualitative synthesis of the data. The multidimensional template included a pre-defined template based on a theoretical framework and a concurrent fully inductive template. RESULTS: Twenty-two papers were included, incorporating the views of 339 doctors from 30 different home countries and 10 different host countries. The resultant theory included 'foundations' (rights and responsibilities) and three pillars. The 'learning' pillar included required knowledge and skills acquisition. The 'being' pillar encompassed necessary identity work. The 'connecting' pillar comprised social connections, which impacted all other domains. The random and non-linear path to integration faced by refugee doctors was also presented as a serious game. DISCUSSION: This study produced a theory exploring refugee doctors' integration needs and how these are met or challenged. Medical educators developing courses for refugee doctors should attend not only to knowledge and skills acquisition but also social connections, identity work and rights and responsibilities. The theory highlights the central importance of social connections. Medical educators can therefore have a transformative impact on refugee doctors' integration. This may also contribute to society by helping to alleviate the workforce crisis.

From safety net to trampoline: elevating learning with growth mindset in healthcare simulation.

The Implicit Theory of Mindset proposes two different mindsets that sit at opposite ends of a spectrum: a fixed mindset versus a growth mindset. With a fixed mindset, an individual believes they are born with a certain amount of an attribute, and so their potential is both pre-determined and static. With a growth mindset, an individual believes their attributes are malleable and can strengthen over time with repeated effort, adaptable learning strategies, and challenge seeking. Adoption of a growth mindset is associated with improved academic success, more effective learning strategies, increased resilience in the face of adversity, and better mental wellbeing.The theoretical underpinning of psychological safety resonates with the Implicit Theory of Mindset as it infers that a significant number of simulation participants have a fixed mindset and are therefore more likely to be fearful of making an error. The simulation community agree that participants need to feel comfortable making errors for simulation to be successful. The key word here is comfortable. Participants feeling comfortable to make errors just scratches the surface of adopting a growth mindset. With a growth mindset, participants see errors as a positive in the simulation experience, an inevitability of the learning process, evidence that they are adequately challenging themselves to improve.Encouraging adoption of a growth mindset in participants is a powerful addition to the establishment of psychological safety because a growth mindset will re-frame participants' experiences of social comparison from negative to positive and optimize information processing. We propose a novel idea: simulation educators should be explicit in the pre-brief about what a growth mindset is and its associated benefits to encourage its adoption during the simulation activity-a simulation growth mindset intervention. If this is not possible due to time constraints, an online module or article about growth mindset would be appropriate as pre-reading to encourage adoption of a growth mindset in participants. The message is not that a simulation growth mindset intervention should replace the focus on psychological safety but rather that it should be used synergistically to provide the highest quality simulation experience.

Rolling the evolutionary dice: Neisseria commensals as proxies for elucidating the underpinnings of antibiotic resistance mechanisms and evolution in human pathogens.

Species within the genus Neisseria are especially adept at sharing adaptive allelic variation across species' boundaries, with commensal species repeatedly transferring resistance to their pathogenic relative N. gonorrhoeae. However, resistance in commensal Neisseria is infrequently characterized at both the phenotypic and genotypic levels, limiting our ability to predict novel and potentially transferable resistance mechanisms that ultimately may become important clinically. Unique evolutionary starting places of each Neisseria species will have distinct genomic backgrounds, which may ultimately control the fate of evolving populations in response to selection, as epistatic and additive interactions may coerce lineages along divergent evolutionary trajectories. However alternatively, similar genetic content present across species due to shared ancestry may constrain the adaptive solutions that exist. Thus, identifying the paths to resistance across commensals may aid in characterizing the Neisseria resistome - or the reservoir of alleles within the genus, as well as its depth. Here, we use in vitro evolution of four commensal species to investigate the potential for and repeatability of resistance evolution to two antimicrobials, the macrolide azithromycin and the ß-lactam penicillin. After 20 days of selection, commensals evolved elevated minimum inhibitory concentrations (MICs) to penicillin and azithromycin in 11/16 and 12/16 cases respectively. Almost all cases of resistance emergence converged on mutations within ribosomal components or the mtrRCDE efflux pump for azithromycin-based selection, and mtrRCDE or penA for penicillin selection; thus, supporting constrained adaptive solutions despite divergent evolutionary starting points across the genus for these particular drugs. However, continuing to explore the paths to resistance across different experimental conditions and genomic backgrounds, which could shunt evolution down alternative evolutionary trajectories, will ultimately flesh out the full Neisseria resistome.
