Living with young-onset dementia in the family - a mixed method study.

Background: Studies on disease-related obstructions experienced in everyday life of younger people with dementia (YOD ≤ 65 years) and their families are encouraged.Aim: To explore how the family carers experience six predefined topics that influence the everyday life and needs of persons with YOD.Method: A quantitative and a qualitative study including family carers of persons with young-onset Alzheimer's dementia (AD) and frontotemporal dementia (FTD). Seventy-four informants responded to the Camberwell Assessment of Needs in the Elderly (CANE) and individual interviews were conducted with 13 informants.Results: Family carers of persons with YOD reported few unmet needs in the CANE assessment. Needs related to behavior and close relationships were reported significantly more frequent (p < 0.1) in persons with FTD than in persons with AD. From the qualitative data, six main themes were emphasized: daily activities turned upside down, involuntary loss of previous social network, losing close relationship, but maintaining a friendship with the spouse, unpredictable behavior adds burdens to a changing life, health and life risks, and economic insecurity for future life and caring costs.Conclusion: Whilst family carers quantitatively reported unmet needs, the individual interviews reported several major difficulties in everyday life.

Electron energy distribution in a dusty plasma: analytical approach.

Analytical expressions describing the electron energy distribution function (EEDF) in a dusty plasma are obtained from the homogeneous Boltzmann equation for electrons. The expressions are derived neglecting electron-electron collisions, as well as transformation of high-energy electrons into low-energy electrons at inelastic electron-atom collisions. At large electron energies, the quasiclassical approach for calculation of the EEDF is applied. For the moderate energies, we account for inelastic electron-atom collisions in the dust-free case and both inelastic electron-atom and electron-dust collisions in the dusty plasma case. Using these analytical expressions and the balance equation for dust charging, the electron energy distribution function, the effective electron temperature, the dust charge, and the dust surface potential are obtained for different dust radii and densities, as well as for different electron densities and radio-frequency (rf) field amplitudes and frequencies. The dusty plasma parameters are compared with those calculated numerically by a finite-difference method taking into account electron-electron collisions and the transformation of high-energy electrons at inelastic electron-neutral collisions. It is shown that the analytical expressions can be used for calculation of the EEDF and dusty plasma parameters at typical experimental conditions, in particular, in the positive column of a direct-current glow discharge and in the case of an rf plasma maintained by an electric field with frequency f=13.56MHz.

Instrument for spatially resolved simultaneous measurements of forces and currents in particle beams.

The article presents a device for spatially resolved and simultaneous measurements of forces and currents in particle beams, especially in beams composed of ions and neutral atoms. The forces are exerted by the impinging beam particles on a plane circular conductive target plate of 20 mm diameter mounted on a pendulum with electromagnetic force compensation. The force measurement in the micronewton range is achieved by electromagnetic compensation by means of static Helmholtz coils and permanent magnets attached to the pendulum. Exemplary measurements are performed in the 1.2 keV beam of a broad beam ion source. The simultaneous measurements of forces and currents onto the same target are compared with each other and with Faraday cup measurements.

Continuing professional development systems and requirements for graduate dentists in the EU: survey results from the DentCPD project.

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.

Guidelines for the organisation of continuing professional development activities for the European dentist.

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.

Core continuing professional development (CPD) topics for the European dentist.

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.

The development of an exemplar e-module for the continuing professional development of European dentists.

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.

Recommendations for the development of e-modules for the continuing professional development of European dentists.

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.

Microparticles in a collisional Rf plasma sheath under hypergravity conditions as probes for the electric field strength and the particle charge.

We used microparticles under hypergravity conditions, induced by a centrifuge, in order to measure nonintrusively and spatially resolved the electric field strength as well as the particle charge in the collisional rf plasma sheath. The measured electric field strengths demonstrate good agreement with the literature, while the particle charge shows decreasing values towards the electrode. We demonstrate that it is indeed possible to measure these important quantities without changing or disturbing the plasma.

Proposed requirements for a European Doctorate in Dentistry: a discussion document prepared by a special interest group under the auspices of the Association for Dental Education in Europe.

In the Bologna process a third cycle is distinguished at the doctoral level. In documents on the Bologna process it is advocated to harmonise the structure and requirements of the doctorate, which in Europe are characterised by a wide variety. Differences exist in all possible requirements between countries, and even between schools within one country differences can be seen. In this paper an inventory is made of these differences in the dental doctorate between European countries. Moreover, the need for necessary harmonisation of requirements for a European dental doctorate is strongly advocated and a proposal is presented.

Surface states and the charge of a dust particle in a plasma.

We investigate electron and ion surface states of a negatively charged dust particle in a gas discharge and identify the charge of the particle with the electron surface density bound in the polarization-induced short-range part of the particle potential. On that scale, ions do not affect the charge. They are trapped in the shallow states of the Coulomb tail of the potential and act only as screening charges. Using orbital-motion limited electron charging fluxes and the particle temperature as an adjustable parameter, we obtain excellent agreement with experimental data.

Curriculum structure: principles and strategy.

This report provides general guidelines for the structure of a curriculum, followed by specific advice on the principles of learning and teaching, the process of restructuring and change leadership and management. It provides examples of several educational philosophies, including vertical and horizontal integration. It discusses the use of competence, learning outcomes, level of degree and assessment and provides a number of recommendations. It does not seek to be prescriptive of time allocation to disciplines within a curriculum. Although this report has been written primarily for those who will develop an undergraduate curriculum, the information may be sufficiently generic to apply to the recent development in graduate entry ('shortened dental' or 'accelerated') courses and to postgraduate degree planning and higher education certificate or diploma courses for other dental care professionals (auxiliaries). The report may have a European bias as progress is made to converge and enhance educational standards in 29 countries with different educational approaches - a microcosm of global collaboration.

Outcome of career expectancies and early professional burnout among newly qualified dentists.

OBJECTIVES: To measure burnout development, outcome of expectations with regard to dental career and feelings of being unprepared for practice among newly graduated general dental practitioners. METHODS: In 1997, 50 dentists were approached to fill in the Maslach Burnout Inventory, Dutch version (UBOS) and some additional variables between six months and one year after graduation at the Academic Centre for Dentistry Amsterdam (ACTA) (76% response). Six years later, in 2003, the same 50 dentists, plus another 60 who had graduated in the same period at ACTA, were approached (78% response). RESULTS: Using Repeated Measures analysis, mean scores of dentists for whom two measurements were available on the three UBOS subscales (N=24) showed no statistically significant changes over six years on Emotional Exhaustion, Depersonalisation, or Personal Accomplishment. The same was true for group means of all in 1997 (N=33) compared with all in 2003 (N=82). However, according to manual criteria, varying percentages (7.2% - 24.4%) of dentists showed an unfavourable level on either one of the UBOS dimensions. Factors most frequently mentioned to be responsible for being unprepared for practice were: law and insurance matters (61.2%), practice organisation (56.6%) and staff management (55.2%). Most frequently reported factors that came out (much) worse than expected were: stressfulness of work (45.1%), and staff management (43.4%). CONCLUSIONS: Burnout appears no threat for the average newly qualified dentist. However, some individuals report alarmingly high burnout scores at an early professional stage. Practice management is the professional aspect about which young professionals worry most. It is recommended that dental schools pay attention to practice management skills and the stressfulness of work in the curriculum. Also, longitudinal monitoring of dental students and newly qualified dentists on burnout development is strongly advocated.

Development and implementation of new educational concepts in a dental curriculum.

The Academic Centre for Dentistry Amsterdam introduced a fully renewed 5-year dental curriculum in September 2003. In this article, the educational principles and didactic choices that form the basis of the curriculum development are presented and attention is given to the process of development and the implementation strategy that constitute such an important part of the success of introducing a new curriculum. Special characteristics of the new curriculum are the clinical training practice, professional conduct, the elective profiles and academic education. In clinical practice, groups of students from different levels run a group practice in which they learn to work together, delegate tasks, solve clinical problems and apply evidence-based dentistry. In the new curriculum students learn to conduct themselves as professionals. In the third and in the fifth year, students choose an elective profile oriented, respectively, on research and on clinical knowledge and skills. Academic education is an important spearhead in this curriculum in which students not only learn why research is important to dentistry but also how dentists can use research to their own benefit. In development and implementation, a stepwise approach was used in which as many people as logistically possible were involved.

Collaboration with school nurses: improving the effectiveness of tuberculosis screening.

OBJECTIVE: To compare tuberculosis skin test (TST) reading rates between children whose tests were read by school nurses following specific requests by physicians and those who relied on their parents to get their tests read, either at school or at the physician's office. DESIGN: A randomized controlled trial. SETTING: An urban hospital-based pediatric practice. PARTICIPANTS: Healthy low-income Hispanic and African American children aged 5 to 17 years whose physicians ordered TSTs at their routine physical examinations. Subjects attended 1 of 68 public schools. Nurses at these schools were willing to read student TSTs, and received instructions about how to read and report the results back to the physician's office. INTERVENTION: Subjects were randomized to a control group (routine TST placement, with no physician-to-school nurse communication) or to an intervention group (routine TST placement, with physician-to-school nurse communication). MAIN OUTCOME MEASURES: Tuberculosis skin test reading rates between the 2 groups were compared. Impediments to TST reading and reporting were investigated. RESULTS: One hundred thirty-four children were enrolled, 54 (40%) in the control group and 80 (60%) in the intervention group. More patients in the intervention group had their TSTs read by 72 hours compared with those in the control group (74 [92%] vs 30 [56%]; P<.001). The low reading rate in the control group was best attributed to communication failures. CONCLUSION: Systematic collaboration with school nurses can increase TST reading rates.

[Dental curriculum and team treatment concept]. / De tandheelkundige opleiding en het teamconcept.

The changing oral situation in the Netherlands, the upgrading of the dental hygienist training and the introduction of the bachelor and master degree in the Dutch higher education system asks for a new dental professional: the oral physician. To prepare the oral physician for his role as leader of a dental team several changes and new developments are necessary in the existing dental curriculum.
