Abstract
Excitatory amino acid transporters (EAATs) are important regulators of amino acid transport and in particular glutamate. Recently, more interest has arisen in these transporters in the context of neurodegenerative diseases. This calls for ways to modulate these targets to drive glutamate transport, EAAT2 and EAAT3 in particular. Several inhibitors (competitive and noncompetitive) exist to block glutamate transport; however, activators remain scarce. Recently, GT949 was proposed as a selective activator of EAAT2, as tested in a radioligand uptake assay. In the presented research, we aimed to validate the use of GT949 to activate EAAT2-driven glutamate transport by applying an innovative, impedance-based, whole-cell assay (xCELLigence). A broad range of GT949 concentrations in a variety of cellular environments were tested in this assay. As expected, no activation of EAAT3 could be detected. Yet, surprisingly, no biological activation of GT949 on EAAT2 could be observed in this assay either. To validate whether the impedance-based assay was not suited to pick up increased glutamate uptake or if the compound might not induce activation in this setup, we performed radioligand uptake assays. Two setups were utilized; a novel method compared to previously published research, and in a reproducible fashion copying the methods used in the existing literature. Nonetheless, activation of neither EAAT2 nor EAAT3 could be observed in these assays. Furthermore, no evidence of GT949 binding or stabilization of purified EAAT2 could be observed in a thermal shift assay. To conclude, based on experimental evidence in the present study GT949 requires specific assay conditions, which are difficult to reproduce, and the compound cannot simply be classified as an activator of EAAT2 based on the presented evidence. Hence, further research is required to develop the tools needed to identify new EAAT modulators and use their potential as a therapeutic target.

Abstract
BACKGROUND Parenteral nutrition (PN) and palliative venting gastrostomies (PVG) are two interventions used clinically to manage inoperable malignant bowel obstruction (MBO); however, little is known about their role in clinical and quality-of-life outcomes to inform clinical decision making. AIM To examine the impact of PN and PVG on clinical and quality-of-life outcomes in inoperable MBO. DESIGN A mixed-methods systematic review and narrative synthesis. DATA SOURCES The following databases were searched (from inception to 29 April 2021): MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, Bielefeld Academic Search Engine, Health Technology Assessment and CareSearch for qualitative or quantitative studies of MBO, and PN or PVG. Titles, abstracts and papers were independently screened and quality appraised. RESULTS A total of 47 studies representing 3538 participants were included. Current evidence cannot tell us whether these interventions improve MBO survival, but this was a firm belief by patients and clinicians informing their decision. Both interventions appear to allow patients valuable time at home. PVG provides relief from nausea and vomiting. Both interventions improve quality of life but not without significant burdens. Nutritional and performance status may be maintained or improved with PN. CONCLUSION PN and PVG seem to allow valuable time at home. We found no conclusive evidence to show either intervention prolonged survival, due to the lack of randomised controlled trials that have to date not been performed due to concerns about equipoise. Well-designed studies regarding survival for both interventions are needed. PROSPERO REGISTRATION NUMBER CRD42020164170.

Abstract
Anorexia is experienced by most people with lung cancer during the course of their disease and treatment. Anorexia reduces response to chemotherapy and the ability of patients to cope with, and complete their treatment leading to greater morbidity, poorer prognosis and outcomes. Despite the significant importance of cancer-related anorexia, current therapies are limited, have marginal benefits and unwarranted side effects. In this multi-site, randomised, double blind, placebo controlled, phase II trial, participants will be randomly assigned (1:1) to receive once-daily oral dosing of 100mg of anamorelin HCl or matched placebo for 12 weeks. Participants can then opt into an extension phase to receive blinded intervention for another 12 weeks (weeks 13-24) at the same dose and frequency. Adults (≥18 years) with small cell lung cancer (SCLC); newly diagnosed with planned systemic therapy OR with first recurrence of disease following a documented disease-free interval ≥6 months, AND with anorexia (i.e., ≤ 37 points on the 12-item Functional Assessment of Anorexia Cachexia Treatment (FAACT A/CS) scale) will be invited to participate. Primary outcomes are safety, desirability and feasibility outcomes related to participant recruitment, adherence to interventions, and completion of study tools to inform the design of a robust Phase III effectiveness trial. Secondary outcomes are the effects of study interventions on body weight and composition, functional status, nutritional intake, biochemistry, fatigue, harms, survival and quality of life. Primary and secondary efficacy analysis will be conducted at 12 weeks. Additional exploratory efficacy and safety analyses will also be conducted at 24 weeks to collect data over longer treatment duration. The feasibility of economic evaluations in Phase III trial will be assessed, including the indicative costs and benefits of anamorelin for SCLC to the healthcare system and society, the choice of methods for data collection and the future evaluation design. Trial registration. The trial has been registered with the Australian New Zealand Clinical Trials Registry [ACTRN12622000129785] and approved by the South Western Sydney Local Health District Human Research Ethics Committee [2021/ETH11339]. https://clin.larvol.com/trial-detail/ACTRN12622000129785.

Abstract
Genomic studies in medulloblastoma have identified distinct disease subgroups: wnt/wingless (WNT), sonic hedgehog (SHH), and non-WNT/non-SHH, comprising group 3 and group 4. Alterations in WNT and SHH signalling form the pathogenetic basis for their subgroups, whereas those for non-WNT/non-SHH tumours remain largely elusive. Recent analyses have revealed recurrent in-frame insertions in the E3 ubiquitin ligase adaptor Kelch Repeat and BTB Domain Containing 4 (KBTBD4) in cases of group 3 and group 4 medulloblastoma. Critically, group 3 and 4 tumours with KBTBD4 mutations typically lack other gene-specific alterations, such as MYC amplification, indicating KBTBD4 insertion mutations as the primary genetic driver of these malignancies. Delineating the role of KBTBD4 mutations in medulloblastoma thus offers significant opportunities to understand its pathogenesis and exploit underpinning mechanisms therapeutically, however their function is currently unknown. Here, we show a novel mechanism in cancer pathogenesis whereby indel mutations in KBTBD4 drive its recognition of neo-substrates for degradation. We observe that KBTBD4 mutants promote the recruitment and ubiquitylation of the REST Corepressor (CoREST), which forms a complex to modulate chromatin accessibility and transcriptional programmes. The degradation of CoREST promoted by KBTBD4 mutations diverts epigenetic programmes inducing significant alterations in transcription to promote increased stemness of cancer cells. Transcriptional analysis of >200 human group 3 and 4 medulloblastomas by RNA-seq, highlights the presence of CoREST and stem-like signatures in tumours with KBTBD4 mutations, which extend to a further sub-set of non-mutant tumours, suggesting CoREST alterations as a novel pathogenetic mechanism of wide relevance in group 3 and 4. Our findings uncover KBTBD4 mutation as a novel driver of epigenetic reprogramming in non-WNT/non-SHH medulloblastoma, establishes a novel mode of tumorigenesis through gain-of-function mutations in ubiquitin ligases (neo-substrate recruitment) and identifies both mutant KBTBD4 and CoREST complexes as new druggable targets for improved tumour-specific therapies.

Abstract
Introduction The two-year, NHS Education for Scotland (NES) post-registration foundation programme supports early career pharmacists in patient-facing sectors of practice. The experiential programme, based on an eight-element competency framework, also includes webinars, online resources, and tutor support. Learners complete an online evidence portfolio and undertake a summative OSCE. Aim The aim of this paper is to report the experiences of the community-pharmacist participants, with a focus on the ‘fitness-for-purpose’ of the programme. Methods This was a longitudinal mixed-methods study theoretically underpinned by Miller’s triangle and social cognitive theory. Eligible participants were all pharmacists registering for the programme in Scotland in September 2017 and February 2018, all participating Welsh community-pharmacists, and all tutors. Invitation packs were emailed by NES/HEIW staff with names forwarded to researchers following signed consent. Focus groups/interviews (face-to-face or virtual according to participant preference) were undertaken at start, mid-point and exit of programme, to explore expectations (benefits, social gains, professional identify), experiences (challenges, facilitators, meeting of learners’ needs) and barriers. Proceedings were digitally recorded, transcribed verbatim and managed using NVivo. Thematic analysis (1) was based on social cognitive theory (transferable behavioural skills and professional attitudes). An inductive analysis additionally identified emergent themes. Participants in Scotland were invited to complete an on-line base-line questionnaire to describe their self-assessed competence against the NES Foundation framework (personal and professional practice, membership of healthcare team, communication, patient centred approach to practice). Data was analysed in SPSS using descriptive statistics. Themes from qualitative and quantitative data were integrated. IRAS ethical approval was not required; NHS Research & Development approval was given. Results 96 pharmacists registered for the programme: 18 community-pharmacists in Scotland (11 health boards); 14 community pharmacists in Wales. In Scotland 15 community-pharmacists completed questionnaires: 9 expected an ‘increase in confidence’ and 11 to provide ‘better patient care’. Self-assessed competence against the framework was generally high. Across Scotland and Wales, 12 focus-groups (involving 19 community-pharmacists), 12 community-pharmacist interviews, 10 tutor focus-groups (8 community-pharmacist tutors) and 3 community-pharmacist tutor interviews were conducted. At midpoint and exit pharmacists and tutors reported increased confidence, the ability to reflect and pride in their achievement. Barriers: included lack of protected time; workload; and lack of support (tutor and employer). There were also programme issues (practicalities of portfolio; workplace-based assessment, no access to medical records); and cultural issues in community-pharmacy (‘speed & safety’; lack of recognition). Reasons for dropping out of the programme included: moved geographical area; too experienced; workload pressures; no incentive; no employer support. Four community-pharmacists in Scotland and none in Wales completed the programme. Conclusion Study limitations include the small numbers, programme delivery limited to Scotland and Wales, and limited response rate to focus-groups/interviews, exacerbated by COVID19. Overall community pharmacist expectations were met, and they perceived the programme was fit-for-purpose and worthwhile.

Abstract
AIM The 75th anniversary of community water fluoridation in the United States was celebrated in 2020. However, there are studies that stimulate polarized discussion over the use of fluoride in dentistry. The purpose of this study was to evaluate dental and dental hygiene students' knowledge and perception of fluoride use in dentistry. MATERIALS AND METHODS A survey was conducted to gauge participant's knowledge and perception of fluoride and their opinion on the need for developing viable alternatives to fluoride. An Institutional Review Board (IRB# 5190496) application was filed and approved. A hard copy survey was distributed to all student classes at Loma Linda University School of Dentistry (U.S.) between January 13, 2020, and February 5, 2020. Descriptive data were compiled and analyzed. Knowledge-based questions were compared using Kruskal-Wallis procedure to evaluate correct percentage among different classes. Perception questions were analyzed using a Likert scale and also a Chi-squared test. All tests were two-sided with α at 0.05. RESULTS Out of 482 students, 282 students responded (58.5%). The mean of correct responses for knowledge ranged from 49 to 69%. There was a statistically significant difference among the classes. Overall the perception of the use of fluoride in dentistry was positive, and it changed with exposure to lectures on fluoride over the years. CONCLUSION There was a correlation between knowledge and the perception of the use of fluoride in dentistry, indicating the importance of adequate delivery of didactic teaching on knowledge of fluoride to dental and dental hygiene students. CLINICAL SIGNIFICANCE The oral healthcare provider plays a pivotal role in communicating pertinent information on the benefits of fluoride in preventing dental caries to the general public, prompting adequate delivery of didactic teaching on this topic in dental education.

Abstract
Despite evidence linking obesity with increased mortality, older adults with excessive adiposity seem protected, resulting in a so-called obesity paradox. Obesity is characterized by leptin resistance, which contributes to increased risk of all-cause mortality. Therefore, lifestyle factors, such as physical fitness, that lower leptin independent of adiposity may be confounding the obesity paradox. To investigate this, we evaluated whether physical fitness moderated the relationship between leptin and adiposity. We found older adults with higher fitness had lower body mass (r(39) = -0.43, p < 0.01), leptin (r(39) = -0.29, p = 0.03) and inflammation (IL-1β: (r(39) = -0.69, p < 0.01); TNF-α: (r(39) = -0.30, p = 0.03)). Fitness moderated the relationship between leptin and adiposity (F(5, 37) = 3.73, p < 0.01, R2 = 0.33) to reveal the obesity paradox in moderately and high fit individuals (b = 216.24, t(37) = 1.46, p = 0.15; b= -88.10, t(37) = -0.49, p = 0.63) but not in low fit individuals. These results show the link between obesity and mortality may not be dependent on total adiposity, but rather on endocrine function and adipocyte leptin secretion. These results have important implications for older adults struggling to maintain healthy body composition and suggest that fitness may promote overall wellbeing.

Abstract
Abstract
Introduction
Individuals with Post Traumatic Stress Disorder (PTSD) often present with insomnia, which may exacerbate other symptoms of the disorder. Morning Blue Light Therapy (BLT) can regulate circadian rhythms and may even improve sleep and mood in individuals with major depressive disorder. However, it is unclear whether morning BLT could also be an effective treatment for the insomnia associated with PTSD. We investigated whether 6 weeks of daily morning BLT would improve insomnia severity and symptom presentation in individuals with PTSD in comparison to a placebo condition of amber light (ALT). We hypothesized that changes in insomnia severity would correlate with improvement in PSTD symptom severity.
Methods
Forty-one participants with a clinical diagnosis of PTSD were randomized to receive 6 weeks of either daily morning BLT (n=22) or ALT (n=19). Insomnia and PTSD symptom severity were evaluated at pre- and post-treatment using the Insomnia Severity Index (ISI) and the Clinician-Administered PTSD Scale (CAPS) for DSM-5, respectively.
Results
Both groups showed a significant decrease in their PTSD symptom severity (p<0.001) and insomnia severity (p<0.001) over the 6-week treatment period. However, improvement in insomnia severity significantly predicted improvements in PTSD symptom severity for the BLT group only (BLT: r =0.542, p=0.009; ALT: r=-0.095, p=0.699). The difference between the two correlation coefficients was significant (Z=-2.07, p=0.039).
Conclusion
The results suggest that morning BLT may be effective in improving PTSD symptoms by regulating the circadian rhythm and improving sleep. While ALT also led to improved PTSD symptom severity, it appears that those changes cannot be explained by improved sleep and may have other underlying mechanisms (e.g., placebo effect). Morning BLT may be a promising adjunctive method to bolster current treatment approaches for PTSD. Because of its ease of administration, it could be easily added to ongoing treatment as usual. This approach warrants further research.

Abstract
Introduction
Disturbing dreams and nightmares are common in individuals with post-traumatic stress disorder (PTSD). At present, little research has investigated the associations between nightmares and cognition in these individuals. However, a robust body of research has shown memory and attention impairments among those with PTSD. The present study sought to investigate the potential relationships between cognitive performance and nightmares in this population.
Methods
Seventy-five individuals (49 female; Mage=31.8, SDage=8.8) were administered the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the PTSD Checklist for the DSM-5 (PCL-5), the Insomnia Severity Index (ISI), the Functional Outcomes of Sleep Questionnaire (FOSQ), the Clinician-Administered PTSD Scale (CAPS), and the Disturbing Dreams and Nightmares Index (DDNSI). Five linear regressions were conducted with index scores on the RBANS subscales (immediate memory, visuospatial/constructional, language, attention, and delayed memory) as the dependent variables and PCL-5, ISI, FOSQ, CAPS symptom class subscales (intrusion, avoidance, cognition, and arousal), and DDNSI scores entered stepwise.
Results
A linear regression revealed that nightmares predicted 15% of the variance in RBANS immediate memory scores (R2 change=.152, β=-.390, p=.003). A second linear regression revealed that nightmares predicted 9.6% of the variance in RBANS visual memory scores (R2 change=.096, β=-.310, p=.019). No other independent variables added to either model. None of the independent variables predicted any variance in language, attention, or delayed memory scores.
Conclusion
Our analysis revealed a unique contribution of nightmares to immediate memory and visuospatial performance in individuals with PTSD. This finding was not better explained by variation in PTSD severity or sleep. Because sleep and dreams are implicated in memory consolidation, one explanation for our finding is that highly distressing trauma-related dreams (i.e. nightmares) may lack the same memory-improving qualities as ordinary dreams. Additionally, given that immediate memory and visuospatial functioning utilize working memory, perhaps nightmares and deficits in working memory share similar mechanisms.

Abstract
Abstract
Introduction
The use of self-referential language, defined as first-person singular pronouns (e.g. I, me, my), in trauma narratives has been found to predict post-traumatic stress disorder (PTSD) severity. Additionally, taking a self-immersed perspective correlates with higher blood pressure reactivity than a self-distanced perspective. Given this relationship between self-immersed perspectives and physiological processes, we investigated the relationship between self-referential language and sleep in people with PTSD, as dysfunctional sleep is a major treatment target in this disorder.
Methods
Seventy-five participants (49 females; Mage=31.8, SDage=8.8) meeting DSM-5 criteria for PTSD were administered the PTSD Checklist for the DSM-5 (PCL-5) and the Pittsburg Sleep Quality Index (PSQI). Sleep duration was assessed with the PSQI. Participants provided typed descriptions of their traumatic event, which were then analyzed using the Linguistic Inquiry and Word Count 2015 software to count instances of first-person singular pronouns (“I” words). Linear regression, with PCL-5 scores and “I” words entered stepwise, was used to predict scores on the PSQI sleep duration subscale. Use of “I” words between the sexes was also compared.
Results
For females but not males, PTSD severity significantly predicted sleep duration (R2=.207, p=.001). Additionally, the number of “I” words in the trauma narratives predicted an additional 8% of the variance in sleep duration for females (R2 change=.083, β=.288, p=.029) but not males. Females used significantly more self-referential language in their narratives (M=11.84, SD=8.42) compared to males (M=5.25, SD=6.10, p=.001).
Conclusion
After controlling for PTSD severity, self-referential language in trauma narratives significantly predicted shorter sleep duration in females. While speculative, this finding suggests that treatment approaches for PTSD may benefit from a focus on targeting self-referential processes to improve sleep and PTSD in females but not males. As dysfunctional sleep is a hallmark of PTSD, further investigation into this relationship may illuminate a new treatment avenue for this disorder.

Abstract
Abstract
Introduction
Sleep difficulties, such as insomnia, are highly prevalent in individuals with Post-Traumatic Stress Disorder (PTSD). However, sleep deprivation can also increase emotional reactivity to positive (as well as negative) stimuli. While the effects of sleep loss on emotional perception healthy individuals has been documented, it remains unclear how lack of sleep in individuals with PTSD may affect their emotional reactivity to positive stimuli. We hypothesized that lower habitual sleep duration would be associated with greater functional brain activation changes in response to subliminally presented happy faces in brain areas of the reward network, such as the rostral anterior cingulate cortex (rACC).
Methods
Thirty-nine individuals with DSM-5 confirmed PTSD were administered the Pittsburgh Sleep Quality Index (PSQI) as a measure of their average nightly sleep duration over the past month. Participants then underwent fMRI imagining while viewing subliminal presentations of faces displaying happiness, using a backward masked facial affect paradigm to minimize conscious awareness of the expressed emotion. Brain activation to masked happy expressions was regressed against sleep duration in SPM12.
Results
There was a negative correlation between habitual sleep duration and activation within the rACC in response to the masked happy faces (x=14,y=40,z=0; k=102, pFWE-corr= 0.008).
Conclusion
Individuals with PTSD who average less sleep at night showed greater emotional reactivity, as indexed by greater functional brain activation changes within an area of the reward network, than individuals who obtained more sleep per night. Future research involving actual sleep duration manipulation will be necessary to determine whether this finding reflects the well-known antidepressant effect of sleep deprivation or a form of greater emotional expression error monitoring among traumatized patients when lacking sleep. Regardless, these findings suggest that insufficient sleep could affect unconsciously perceived emotion in faces and potentially affect social and emotional responses among individuals with PTSD.

Abstract
Abstract
Introduction
Individuals with Post-Traumatic Stress Disorder (PTSD) often experience poor sleep quality and elevated self-destructive behaviors. Among healthy individuals, poor sleep quality can lead to increased risk-taking behavior through decreased inhibition and/or increased willingness to take risks. However, it is unclear whether racial/ethnic background may influence this relationship, in particular among individuals with PTSD. We examined whether the relationship between sleep quality and risk propensity would differ between majority and minority racial groups in individuals with PTSD.
Methods
Seventy-six individuals (61.8% female; mean age=31.7, SD=8.8) with a clinical diagnosis of PTSD were administered the Functional Outcomes of Sleep Questionnaire (FOSQ) as a measure of sleep-related functional impairment of daily activities, and the Evaluation of Risk (EVAR) Scale as a measure of risk-taking propensity. Forty-seven individuals identified with the majority racial group (Caucasian) and 29 individuals identified themselves within the minority.
Results
There were no significant group differences for FOSQ and total EVAR risk-taking scores. However, the strength of association between measures differed significantly between groups (Z=1.95, p=.051). For the racial/ethnic majority, functional impairments due to lack of sleep were positively associated with risk-taking propensity (r=.460, p=.001); this relationship was not present for the minority group (r=.016, p=.936).
Conclusion
Self-reported functional impairments due to sleep loss significantly correlated with risk-taking propensity for those who identified themselves as part of the majority racial group but not for individuals who identified as part of a racial minority. Findings suggest that broad conclusions regarding the association between sleep disruption and risk-taking may not apply equally across racial/ethnic groups and such factors should be considered when evaluating studies of sleep and risk behaviors. Whether these differing effects are due to cultural factors or stable differences in biology is not known and will require additional research.

Abstract
Meds4Kids Pharma (M4K)1 is pioneering an open science approach to drug discovery, focussed on the discovery and development of small molecule therapeutics for orphan paediatric cancers. M4K seeks to test the hypothesis that an open science framework can be successfully applied not only to accelerate basic science, using the collective knowledge of the scientific community at large, but also to take an innovative new drug candidate all the way from discovery and clinical proof-of-concept through to product registration, by making use of regulatory data protections and market incentives. Since late 2017, Charles River Early Discovery has been providing in kind drug discovery services to help progress these efforts, including medicinal and synthetic chemistry. The first M4K project aims to generate an orally-available, brain-penetrant therapeutic to treat the diffuse intrinsic pontine glioma (DIPG). DIPG is a rare, aggressive and uniformly fatal childhood brain cancer with a median survival time of 9-12 months and for which there are currently no effective drug treatments. The disease has been shown to be associated with mutations in the ACVR1 gene (activin A receptor, type 1) also known as ALK2 kinase. Early support for the therapeutic hypothesis that an inhibitor of ALK2 kinase would have clinical benefit in DIPG, came from in vivo studies with non-selective ALK2 kinase inhibitors, which both killed DIPG cell lines harbouring the ALK2 mutation and extended lifespan in xenograft mouse models.2 Working collaboratively with M4K and their open science partners, we have made excellent progress towards the identification of potent, selective, brain penetrant ALK2 inhibitors starting from the known inhibitor LDN-214117, previously described for FOP (fibrodysplasia ossificans progressiva).3 Our current lead compound has an excellent in vitro and in vivo profile showing high oral bioavailability and brain penetration in a mouse PK study and is progressing to proof of concept studies. In addition we are progressing with the identification of a back-up series. References: 1. https://m4kpharma.com/ 2. Carvalho et. al.

Abstract
INTRODUCTION Culture is an important factor influencing how students develop learning and how educators provide support to students. The aim of this paper is to explore a concept of national European cultures, and relationships between culture and educational practice with the intention of helping the dental profession gain a better understanding of effective teaching and learning in dentistry. CONTENT Culture represents the collective behaviours, values and beliefs of people in a society. How people react to education is partly explained by culture. Students utilise different culturally based strategies to develop learning. We apply Hofstede's model to explore European cultures and implications for dental education and educational practice. Most Western students possess assimilating learning styles enabling them to learn effectively in student-centred contexts while most Eastern students have accommodating learning styles and are more familiar with teacher-centred learning. Eastern students may need to adapt their approach to learning to better benefit from student-centred learning. CONCLUSION Culture influences students' learning and educational practice. Dental educators should be aware of such influences and provide support that acknowledges students' different cultural backgrounds. Cultural competence is fundamental for effective teaching and learning in dentistry.

Abstract
INTRODUCTION Dental educators are important people who contribute to the development of every aspect of dental education. In part due to the lack of understanding of their roles and competences, dental educator development has so far received little consideration. With the aim of enhancing the dental profession's contribution to the development of undergraduate dental education, this article explores common roles of educators of undergraduate dental students and the competences needed to be effective educators. METHODS This is a discussion paper based on a wide reading of the literature on the education of health professionals with a specific focus on roles and competences of educators. RESULTS AND DISCUSSION Roles of educators of undergraduate dental students typically encompass four areas: teaching, research, administration and providing healthcare. Educators may not be involved in every role; they normally perform the roles relevant to their work contexts. Competences for dental educators based on the four main roles comprise 12 domains: educational theories and principles; modes of education; learner issues; educational materials and instructional design; assessment and feedback; curriculum matters; evaluation; educational research; educational management; quality assurance; patient care and healthcare system and professionalism. Not all competences are required by all educators although educators need to be competent in the areas related to their roles and duties. CONCLUSION Understanding the roles and competences for educators of undergraduate dental students can help individual educators to improve their personal effectiveness and institutions to tailor staff development programmes appropriate to the needs of their staff. Faculty development contributes to sustained enhancement of undergraduate dental education.

Abstract
OBJECTIVES The Shape of Training report recommended that full registration is aligned with medical school graduation. As part of a General Medical Council-funded study about the preparedness for practice of UK medical graduates, we explored UK stakeholders' views about this proposal using qualitative interviews (30 group and 87 individual interviews) and Framework Analysis. SETTING Four UK study sites, one in each country. PARTICIPANTS 185 individuals from eight stakeholder groups: (1) foundation year 1 (F1) doctors (n=34); (2) fully registered trainee doctors (n=33); (3) clinical educators (n=32); (4) undergraduate/postgraduate Deans, and Foundation Programme Directors (n=30); (5) other healthcare professionals (n=13); (6) employers (n=7); (7) policy and government (n=11); (8) patient and public representatives (n=25). RESULTS We identified four main themes: (1) The F1 year as a safety net: patients were protected by close trainee supervision and 'sign off' to prevent errors; trainees were provided with a safe environment for learning on the job; (2) Implications for undergraduate medical education: if the proposal was accepted, a 'radical review' of undergraduate curricula would be needed; undergraduate education might need to be longer; (3) Implications for F1 work practice: steps to protect healthcare team integration and ensure that F1 doctors stay within competency limits would be required; (4) Financial, structural and political implications: there would be cost implications for trainees; clarification of responsibilities between undergraduate and postgraduate medical education would be needed. Typically, each theme comprised arguments for and against the proposal. CONCLUSIONS A policy change to align the timing of full registration with graduation would require considerable planning and preliminary work. These findings will inform policymakers' decision-making. Regardless of the decision, medical students should take on greater responsibility for patient care as undergraduates, assessment methods in clinical practice and professionalism domains need development, and good practice in postgraduate supervision and support must be shared.

Abstract
AIMS To provide evidence-based and peer-reviewed recommendations for the development of dental continuing professional development (CPD) learning e-modules. METHODS The present recommendations are consensus recommendations of the DentCPD project team and were informed by a literature research, consultations from e-learning and IT expert, discussions amongst the participants attending a special interest group during the 2012 ADEE meeting, and feedback from the evaluation procedures of the exemplar e-module (as described in a companion paper within this Supplement). The main focus of these recommendations is on the courses and modules organised and offered by dental schools. RESULTS AND DISCUSSION E-modules for dental CPD, as well as for other health professionals' continuing education, have been implemented and evaluated for a number of years. Research shows that the development of e-modules is a team process, undertaken by academics, subject experts, pedagogists, IT and web designers, learning technologists and librarians. The e-module must have clear learning objectives (outcomes), addressing the learners' individual needs, and must be visually attractive, relevant, interactive, promoting critical thinking and providing feedback. The text, graphics and animations must support the objectives and enable the learning process by creating an attractive, easy to navigate and interactive electronic environment. Technology is usually a concern for learners and tutors; therefore, it must be kept simple and interoperable within different systems and software. The pedagogical and technological proficiency of educators is of paramount importance, yet remains a challenge in many instances. CONCLUSIONS The development of e-courses and modules for dental CPD is an endeavour undertaken by a group of professionals. It must be underpinned by sound pedagogical and e-learning principles and must incorporate elements for effective visual learning and visual design and a simple, consistent technology.

Abstract
AIM Free movement of dental professionals across the European Union calls for more uniform continuing education in dentistry to ensure up-to-date, high-quality patient care and patient safety. This article provides guidelines for the management and delivery of high-quality continuing professional development (CPD) by European dental schools and other CPD providers. METHOD The guidelines are based on an extensive literature inventory, a survey of existing practices (both available as separate publications), discussions during meetings of the Association for Dental Education in Europe in 2011 and 2012 and debate amongst the members of the DentCPD project team representing six dental schools. RESULTS On the basis of the literature review, survey and discussions, we recommend that (i) every dentist should be given the opportunity for CPD, (ii) providers should be quality-approved and impartial, (iii) educators should be approved, impartial, suitably trained, and with educational expertise, (iv) the mode of CPD delivery should suit the educational activity, with clear learning objectives or outcomes, (v) effort should be made to assess the learning, (vi) participant feedback should be collected and analysed to inform future developments and (vii) uniform use of the pan-European system of learning credit points (ECTS) should be implemented. CONCLUSION Implementation of these guidelines should make dental CPD more transparent to all relevant parties and facilitate the transferability of earned credits across the European Union. It will also enable better quality control within dentistry, resulting in enhanced dental care and ultimately the improvement in patient safety.

Abstract
AIM To present the development of an exemplar e-module for dental continuing professional development (CPD) provided by dental schools and other dental educational providers. MATERIALS AND METHODS The exemplar e-module covered the topic of 'Sterilisation and cross-infection control in the dental practice' as this is one of the most recommended topics for dental CPD in Europe. It was developed by a group of topic experts, adult learning and distance learning experts and a technical developer. Major concerns were pedagogy, interoperability, usability and cost reduction. Open-source material was used to reduce the cost of development. RESULTS The e-module was pre-piloted in dental practitioners for usability and then evaluated by experts in the field and dental academics through an electronic questionnaire and an online presentation and discussion at the ADEE 2012 Special Interest Group on DentCPD-Lifelong learning. This facilitated refinement before final production. A Creative Commons License was implemented to ensure the developers' rights and facilitate wider distribution and access to CPD providers. DISCUSSION AND CONCLUSIONS The e-module was developed according to well-defined pedagogical and technical guidelines for developing e-learning material for adult learners. It was structured to promote self-study by directing learners through their study, promoting interaction with the material, offering explanation and providing feedback. Content validity was ensured by extensive review by experts. The next step would be to expand the evaluation to practising dentists in various countries after relevant translations, and adaptations to local policies have been made.
