Abstract
BACKGROUND Low fibrinogen (Fg) concentrations in trauma haemorrhage are associated with poorer outcomes. Cryoprecipitate is the standard source for Fg administration in the UK and USA and is often given in the later stages of transfusion therapy. It is not known whether early cryoprecipitate therapy improves clinical outcomes. The primary aim of this feasibility study was to determine whether it was possible to administer cryoprecipitate, within 90 min of admission to hospital. Secondary aims were to evaluate laboratory measures of Fg and clinical outcomes including thrombotic events, organ failure, length of hospital stay and mortality. METHODS This was an unblinded RCT, conducted at two civilian UK major trauma centres of adult trauma patients (age ≥16 yrs), with active bleeding and requiring activation of the major haemorrhage protocol. Participants were randomised to standard major haemorrhage therapy (STANDARD) (n=22), or to standard haemorrhage therapy plus two early pools of cryoprecipitate (CRYO) (n=21). RESULTS 85% (95% CI: 69-100%) CRYO participants received cryoprecipitate within 90 min, median time 60 min (IQR: 57-76) compared with 108 min (67-147), CRYO and STANDARD arms respectively (P=0.002). Fg concentrations were higher in the CRYO arm and were maintained above 1.8 g litre(-1) at all time-points during active haemorrhage. All-cause mortality at 28 days was not significantly different (P=0.14). CONCLUSIONS Early Fg supplementation using cryoprecipitate is feasible in trauma patients. This study supports the need for a definitive RCT to determine the effect of early Fg supplementation on mortality and other clinical outcomes. TRIAL REGISTRY NUMBER ISRCTN55509212.

Abstract
BACKGROUND Prophylactic mastectomy (PM) has become increasingly common but is not without complications especially if accompanied by reconstructive surgery. In patients with sporadic unilateral breast cancer, contralateral PM offers no survival advantage. Multidisciplinary team (MDT) communication and interaction may facilitate shared decision-making and curtail PM rates. The aim of this study was investigate the effect of a regional MDT meeting on PM decision-making. METHODS We conducted an observational study involving retrospective review of prospectively recorded MDT meeting records for a 151 patient requests for PM from 2011 to 2014. Final MDT decisions were recorded as PM 'accepted', 'declined' or 'pending'. For MDT sanctioned requests, the factors justifying PM were recorded. Where PM was declined, justification for MDT refusal was sought and recorded. RESULTS Approximately half of all requests for PM have been upheld (53.0%) and 1/3 of requests have been declined (32.5%). Of those declined, low risk of contralateral breast cancer versus relatively high risk of systemic relapse were commonly cited as justification for PM refusal (45.7%). A proportion of patients who initiated PM discussion subsequently changed their minds (19.6%), or failed to attend clinic appointments (6.5%). Some patients were deemed medically unfit for complex reconstructive surgery (13%), or were declined on the basis of an apparent cosmetic drive for surgery (6.5%), concerns regarding depression or anxiety (2.2%) and/or if family history could not be substantiated (6.5%). DISCUSSION MDT meetings facilitate cross-specialty interrogation of requests for PM, minimise unnecessary surgery and restrict PM to those likely to derive maximum benefit.

Abstract
BACKGROUND Recent cross-sectional studies have shown psychotic experiences (PEs) are associated with suicidal ideation and behaviours. We aimed to examine associations between psychotic experiences (including persistent PE), and contemporaneous and incident non-suicidal self-injury (NSSI) and suicide attempts. METHOD Participants were from an Australian longitudinal cohort of 1896 adolescents (12-17 years). NSSI and suicide attempts were measured using the Self-Harm Behaviour Questionnaire. Items from the Diagnostic Interview Schedule for Children were used to assess psychotic experiences, and the General Health Questionnaire-12 measured psychological distress. RESULTS Adolescents both psychologically distressed and endorsing psychotic experiences had increased odds of contemporaneous and incident NSSI and attempted suicide. Psychotic experiences alone did not predict future risk. Persistent psychotic experiences were associated with increased risk of NSSI and suicide attempts. CONCLUSIONS Psychological distress with accompanying psychotic experiences and persistent psychotic experiences are important predictors of NSSI and suicide attempts. Screening these phenotypes in adolescents will assist in discerning those adolescents most at risk, providing opportunities for targeted suicide prevention strategies.

Abstract
This article focuses on sequence learning on the Visual Expectation Paradigm (VExP) using human faces as stimulus material. For a sample of 133 Caucasian German infants assessed longitudinally at 3 and 6 months of age, a previous study has shown that the response latency of 6-month-old infants was shorter when the infants solved the task with Caucasian own-race faces in contrast to African other-race faces. The advantage for own-race faces occurs at the same age the Other-Race-Effect (ORE) has been reported to emerge. As studies on ORE development have shown the phenomenon in infants from various cultural backgrounds, the follow-up question to be answered here is whether the performance differences on the VExP can also be found in other than Caucasian infants. As a complement to the German sample, 30 African infants from Cameroon were assessed longitudinally with the same VExP task at ages 3 and 6 months. Our results indicate that perception differences between own-race and other-race faces influence performance on the VExP in both samples. As expected, the Cameroonian infants improved performance on the VExP from 3 to 6 months only in their own-race African faces condition.

Abstract
In the yeasts C. albicans, C. tropicalis, and C. stellatoidea but not in C. krusei, R. rubra, and S. cerevisiae enzyme activity was found by which - as by the catechol-O-methyltransferase (EC 2.1.1.6) found in the liver - the O-methylation of epinephrine to metanephrine and paranephrine, of 3,4-dihydroxybenzoic acid to 4-hydroxy-3-methoxybenzoic acid and 3-hydroxy-4-methoxybenzoic acid, and of 6,7-dihydroxycoumarin to 7-hydroxy-6-methoxycoumarin and 6-hydroxy-7-methoxy-coumarin is catalysed.
When the substrates 3,4-dihydroxybenzoic acid, or 6,7-dihydroxycoumarin or epinephrine were incubated in the presence of S-adenosyl-ʟ-[methyl-14C] methionine and S-adenosylmethionine hydrogensulfate with a 100 000 X g supernatant of C. albicans, C. tropicalis or C. stellatoidea the corresponding O-methylethers were detected in the extracts of the incubation medium by thin-layer chromatography.
Final identification of the isomeric radioactive O-methylethers obtained from 3,4-dihydroxy benzoic acid and 6,7-dihydroxycoumarin was performed after thin-layer chromatographic separation by the reversed isotope dilution technique.
The radioactive m-and p-O-methyl derivatives from epinephrine were separated by thin-layer chromatography and then cleaved with periodate to the corresponding aldehydes which were also identified mainly by the reversed isotope dilution technique.

Abstract
6,7-Dihydroxycoumarin (Aesculetin) was found to be a substrate of rat liver Catechol-O-methylfransferase (COMT) (EC 2.1.1.6).
Incubation of this substrate with S-Adenosyl-ʟ-[methyl-14C] methionine and/or S-Adenosyl- methionin-hydrogensulfate in the presence of COMT yields the highly fluorescent compounds 7-hydroxy-6-methoxycoumarin (Scopoletin) and 6-hydroxy-7-methoxycoumarin (Isoscopoletin) in the ration of about 2:1. The O-methylated products obtained from Aesculetin were identified after separation by thin layer chromatographpy mainly by the reversed isotope dilution technique.
The fluorescence of the isolated methylethers was proportional to concentration within the range from 10-5 - 10-7M. A reciprocal plot of activity versus substrate concentration gives a Km of 1 × 10-6 M.

Abstract
Background: Poly(ADP-ribose) polymerase-1 (PARP) inhibitors (PARPi) exploit tumour-specific defects in homologous recombination DNA repair and continuous dosing is most efficacious. Early clinical trial data with rucaparib suggested that it caused sustained PARP inhibition. Here we investigate the mechanism of this durable inhibition and potential exploitation. Methods: Uptake and retention of rucaparib and persistence of PARP inhibition were determined by radiochemical and immunological assays in human cancer cell lines. The pharmacokinetics and pharmacodynamics of rucaparib were determined in tumour-bearing mice and the efficacy of different schedules of rucaparib was determined in mice bearing homologous recombination DNA repair-defective tumours. Results: Rucaparib accumulation is carrier mediated (Km=8.4±1.2 μM, Vmax=469±22 pmol per 106 cells per 10 min), reaching steady-state levels >10 times higher than the extracellular concentration within 30 min. Rucaparib is retained in cells and inhibits PARP ⩾50% for ⩾72 h days after a 30-min pulse of 400 nM. In Capan-1 tumour-bearing mice rucaparib accumulated and was retained in the tumours, and PARP was inhibited for 7 days following a single dose of 10 mg kg−1 i.p or 150 mg kg−1 p.o. by 70% and 90%, respectively. Weekly dosing of 150 mg kg−1 p.o once a week was as effective as 10 mg kg−1 i.p daily for five days every week for 6 weeks in delaying Capan-1 tumour growth. Conclusions: Rucaparib accumulates and is retained in tumour cells and inhibits PARP for long periods such that weekly schedules have equivalent anticancer activity to daily dosing in a pre-clinical model, suggesting that clinical evaluation of alternative schedules of rucaparib should be considered.

Abstract
BACKGROUND Discovery of adequate pharmacological treatments for constipation has proven elusive. Increased numbers of bowel movements were reported as a side-effect of ulimorelin treatment of gastroparesis, but there has been no investigation of the site of action. METHODS Anesthetized rats were used to investigate sites and mechanisms of action of ulimorelin. KEY RESULTS Intravenous ulimorelin (1-5 mg/kg) caused a substantial and prolonged (~1 h) increase in colorectal propulsive activity and expulsion of colonic contents. This was prevented by cutting the nerves emerging from the lumbosacral cord, by the nicotinic receptor antagonist hexamethonium and by antagonists of the ghrelin receptor. The effect of intravenous ulimorelin was mimicked by direct application of ulimorelin (5 μg) to the lumbosacral spinal cord. CONCLUSIONS & INFERENCES Ulimorelin is a potent prokinetic that causes propulsive contractions of the colorectum by activating ghrelin receptors of the lumbosacral defecation centers. Its effects are long-lasting, in contrast with other colokinetics that target ghrelin receptors.

Abstract
The burden of disease due to chronic viral hepatitis constitutes a global threat. In many Balkan and Mediterranean countries, the disease burden due to viral hepatitis remains largely unrecognized, including in high-risk groups and migrants, because of a lack of reliable epidemiological data, suggesting the need for better and targeted surveillance for public health gains. In many countries, the burden of chronic liver disease due to hepatitis B and C is increasing due to ageing of unvaccinated populations and migration, and a probable increase in drug injecting. Targeted vaccination strategies for hepatitis B virus (HBV) among risk groups and harm reduction interventions at adequate scale and coverage for injecting drug users are needed. Transmission of HBV and hepatitis C virus (HCV) in healthcare settings and a higher prevalence of HBV and HCV among recipients of blood and blood products in the Balkan and North African countries highlight the need to implement and monitor universal precautions in these settings and use voluntary, nonremunerated, repeat donors. Progress in drug discovery has improved outcomes of treatment for both HBV and HCV, although access is limited by the high costs of these drugs and resources available for health care. Egypt, with the highest burden of hepatitis C in the world, provides treatment through its National Control Strategy. Addressing the burden of viral hepatitis in the Balkan and Mediterranean regions will require national commitments in the form of strategic plans, financial and human resources, normative guidance and technical support from regional agencies and research.

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.

Abstract
INTRODUCTION By maintaining skills and keeping dentists up-to-date, continuing professional development (CPD) supports safe clinical practice. However, CPD for dentists across Europe is not harmonised. AIM One aim of the 'DentCPD' project (www.dentcpd.org) was to identify and agree essential CPD requirements for EU dentists. As part of the process, data were collected on existing approaches to CPD for EU dentists. This paper reports those findings. METHODS Informed by a review of the literature and internet search, the CPD for Graduate Dentists questionnaire gathered data from dental educators on CPD systems, requirements, provision and accreditation in Europe. It sought opinion on mandatory CPD and e-learning. RESULTS Responses were received from 143 individuals from 30 EU countries. About half the countries had a compulsory CPD system which typically included mandatory core topics. Elsewhere CPD was optional or based on recommended hours. University dental schools and professional dental associations were the most common CPD providers. National regulatory bodies were the most common accrediting body. Only 41% of respondents thought they knew the criteria for successful accreditation of CPD. Eighty-one percent agreed that 'CPD should be obligatory for all dentists'. CONCLUSION These results present an overview of the status of CPD for EU dentists. Despite a notable trend towards regulated CPD systems, current requirements for dentists to engage in CPD show variation. The harmonisation of requirements would enhance both dentist mobility and safe clinical practice.

Abstract
INTRODUCTION In the context of free movement, EU-citizens need assurance that dental practitioners providing their care have a degree/license to practice that meets EU-standards and that they maintain their knowledge and skills through ongoing education. AIM One aim of the 'DentCPD' project (HYPERLINK 'http://www.dentcpd.org' www.dentcpd.org) was to identify and agree essential CPD requirements for EU dentists. This paper reports the consensus process and outcomes. METHODS Agreement on core components of CPD was achieved through a three stage process: an online survey of dental educators' (n = 143) views on compulsory topics; a paper-based questionnaire to practitioners (n = 411); leading to a proposal discussed at the Association for Dental Education (ADEE) 2011 Lifelong Learning special interest group (SIG). RESULTS From the online survey and practitioner questionnaire, high levels of agreement were achieved for medical emergencies (89%), infection control (79%) and the medically compromised patient (71%). The SIG (34 attendees from 16 countries) concluded that these three CPD topics plus radiation protection should be core-compulsory and three CPD topics should be core-recommended (health and safety, pain management, and safeguarding children & vulnerable adults). They also agreed that the teaching of all topics should be underpinned by evidence-based dentistry. CONCLUSION Building four core topics into CPD requirements and making quality-approved education and training available will ensure that all dentists have up-to-date knowledge and skills in topic areas of direct relevance to patient safety. In turn, this will contribute to patients having access to comparably high standards of oral health care across Europe.
