Diabète et conduite: réflexions et atelier pratique [Diabetes and driving: thoughts and educational perspectives].

In Switzerland over 200'000 people with diagnosed diabetes drive a car. Their physicians endorse many roles: usual medical care as well as informing properly about driving recommandations and handling the legal issues behing the licensing procedure. Ability to drive can be impaired in three ways: hypogylcemia, diabetes complications and hyperglycemia. Hypoglycemia is the main risk factor of vehicle accident for diabetic drivers and frequent while driving. However few accidents are reported due to hypoglycemia. Swiss medical guidelines about diabetes and driving mention the requested conditions, but practically how should we do? We sought to answear by creating a specific educationnal program focused on hypoglycemia management. Building patient knowledges through experiences is the main goal of the course diabetes and driving.

Impact, challenges and perspectives of Euromelanoma, a pan-European campaign of skin cancer prevention.

The serotonin-2A receptor (5-HT(2A)R) has been implicated in the pathogenesis of schizophrenia and related inhibitory gating and behavioral inhibition deficits of schizophrenia patients. The hallucinogen psilocybin disrupts automatic forms of sensorimotor gating and response inhibition in humans, but it is unclear so far whether the 5-HT(2A)R or 5-HT(1A)R agonist properties of its bioactive metabolite psilocin account for these effects. Thus, we investigated whether psilocybin-induced deficits in automatic and controlled inhibition in healthy humans could be attenuated by the 5-HT(2A/2C)R antagonist ketanserin. A total of 16 healthy participants received placebo, ketanserin (40 mg p.o.), psilocybin (260 μg/kg p.o.), or psilocybin plus ketanserin in a double-blind, randomized, and counterbalanced order. Sensorimotor gating was measured by prepulse inhibition (PPI) of the acoustic startle response. The effects on psychopathological core dimensions and behavioral inhibition were assessed by the altered states of consciousness questionnaire (5D-ASC), and the Color-Word Stroop Test. Psilocybin decreased PPI at short lead intervals (30 ms), increased all 5D-ASC scores, and selectively increased errors in the interference condition of the Stroop Test. Stroop interference and Stroop effect of the response latencies were increased under psilocybin as well. Psilocybin-induced alterations were attenuated by ketanserin pretreatment, whereas ketanserin alone had no significant effects. These findings suggest that the disrupting effects of psilocybin on automatic and controlled inhibition processes are attributable to 5-HT(2A)R stimulation. Sensorimotor gating and attentional control deficits of schizophrenia patients might be due to changes within the 5-HT(2A)R system.

The future of leadership

The good news with regard to this (or any) chapter on the future of leadership is that there is one. There was a time when researchers called for a moratorium on new leadership theory and research (e.g., Miner, 1975) citing the uncertain future of the field. Then for a time there was a popular academic perspective that leadership did not really matter when it came to shaping organizational outcomes (Meindl & Ehrlich, 1987; Meindl, Ehrlich, & Dukerich, 1985; Pfeffer, 1977). That perspective was laid to rest by "realists" in the field (Day & Antonakis, 2012a) by means of empirical re-interpretation of the results used to support the position that leadership does not matter (Lieberson & O'Connor, 1972; Salancik & Pfeffer, 1977). Specifically, Day and Lord (1988) showed that when proper methodological concerns were addressed (e.g., controlling for industry and company size effects; incorporating appropriate time lags) that the impact of top-level leadership was considerable - explaining as much as 45% of the variance in measures of organizational performance. Despite some recent pessimistic sentiments about the "curiously unformed" state of leadership research and theory (Hackman & Wageman, 2007), others have argued that the field has continued to evolve and is potentially on the threshold of some significant breakthroughs (Day & Antonakis, 2012a). Leadership scholars have been re-energized by new directions in the field and research efforts have revitalized areas previously abandoned for apparent lack of consistency in findings (e.g., leadership trait theory). Our accumulated knowledge now allows us to explain the nature of leadership including its biological bases and other antecedents, and consequences with some degree of confidence. There are other comprehensive sources that review the extensive theoretical and empirical foundation of leadership (Bass, 2008; Day & Antonakis, 2012b) so that will not be the focus of the present chapter. Instead, we will take a future-oriented perspective in identifying particular areas within the leadership field that we believe offer promising perspectives on the future of leadership. Nonetheless, it is worthwhile as background to first provide an overview of how we see the leadership field changing over the past decade or so. This short chronicle will set the stage for a keener understanding of where the future contributions are likely to emerge. Overall, across nine major schools of leadership - trait, behavioural, contingency, contextual, relational, sceptics, information processing, New Leadership, biological and evolutionary - researchers have seen a resurgence in interest in one area, a high level of activity in at least four other areas, inactivity in three areas, and one that was modestly active in the previous decade but we think holds strong promise for the future (Gardner, Lowe, Moss, Mahoney, & Cogliser, 2010). We will next provide brief overviews of these nine schools and their respective levels of research activity (see Figure 1).

How can continuing professional development better promote shared decision-making? Perspectives from an international collaboration.

ABSTRACT: BACKGROUND: Shared decision-making is not widely implemented in healthcare. We aimed to set a research agenda about promoting shared decision-making through continuing professional development. METHODS: Thirty-six participants met for two days. RESULTS: Participants suggested ways to improve an environmental scan that had inventoried 53 shared decision-making training programs from 14 countries. Their proposed research agenda included reaching an international consensus on shared decision-making competencies and creating a framework for accrediting continuing professional development initiatives in shared decision-making. CONCLUSIONS: Variability in shared decision-making training programs showcases the need for quality assurance frameworks.

Intravitreal chemotherapy for vitreous seeding in retinoblastoma: Recent advances and perspectives.

For decades intravitreal chemotherapy (IViC) remained virtually banished from the therapeutic armamentarium against retinoblastoma, except as a heroic attempt of salvage before enucleation in only eyes with refractory vitreous seeding. Very recently, we have initiated a reappraisal of this route of administration by (1) profiling eligibility criteria, (2) describing a safety-enhanced injection procedure, (3) adjusting the tumoricidal dose of melphalan, and (4) reporting an unprecedented efficacy in terms of tumor control of vitreous seeding. Since then, intravitreal chemotherapy is being progressively implemented worldwide with great success, but still awaits formal validation by the ongoing prospective phase II clinical trial. As far as preliminary results are concerned, IViC appears to achieve complete vitreous response in 100% of the 35 newly recruited patients irrespective of the previous treatment regimen, including external beam radiotherapy and/or intra-arterial melphalan. In other words, vitreous seeding, still considered as the major cause of primary and secondary enucleation, can now be controlled by IViC. However, sterilization of vitreous seeding does not necessarily translate into eye survival, unless the retinal source of the seeds receives concomitant therapy. In conclusion, IViC, an unsophisticated and cost-effective treatment, is about to revolutionize the eye survival prognosis of vitreous disease in advanced retinoblastoma.

Pédiatrie. 3. Traitement du membre supérieur dans les hémiparésies congénitales: progrès et perspectives [Pediatrics. Upper limb treatment in congenital hemiparesis: progress and perspectives].

Congenital hemiparesis is one of the most frequent pediatric motor disorders. Upper limb rehabilitation of the hemiparetic child has considerably evolved during the last decade by the use of focal chemical denervation (intramuscular botulinum toxin) and the introduction of novel rehabilitation techniques such as constraint induced movement therapy or robotic reeducation.

Fourmis des bois en Suisse: état de la situation et perspectives de monitoring

The authors summarise their state of knowledge about wood ants and their role in the forest ecosystem. They also describe the situation in Switzerland, their past development and their conservation status. In several re- gions, mainly in the Plateau, wood ants seem to diminish, despite their total protection since 1966. The reasons for this regression are not well known, but the fragmentation of forest habitats in the Plateau region and direct damage to ant nests seem to play a certain role. A new project in which the development of wood ant nests is monitored in Swiss forest reserves (Formica-Forêts-CH) was recently started in the Swiss national park. It is to be extended, in collaboration with the forest services, over the whole of Switzerland.

Epilogue: Etre musulman en Suisse, hors mosquée. Notes méthodologiques et perspectives épistémologiques

En Suisse, un peu moins de 5 % de la population se déclarent musulmans. Originaires pour la majeure partie des grandes vagues migratoires de la fin du XXe siècle, les musulmans helvétiques sont le plus souvent identifiés individuellement. Ce livre présente la réalité institutionnelle et peu connue de l'islam en Suisse à partir de plusieurs enquêtes menées sur la manière dont il s'organise. Sa présence est très diversifiée selon les contextes cantonaux différents et les origines culturelles bien contrastées d'un musulman des Balkans, du Maghreb ou de la Turquie. Ces recherches menées par des sociologues et des politologues dessinent une mosaïque qui montre à partir de l'islam pratiquant et confessant qu'il ne peut être réduit aux formes conservatrices et violentes que certains considèrent comme la traduction obligée de toute posture musulmane. Cet ouvrage propose un portrait contrasté de l'islam en Suisse avec, d'une part, des ensembles qui tentent d'organiser légitimement leur culte et de maintenir leur héritage religieux et, d'autre part, des défis déterminants à relever pour l'intégration des fidèles, comme les liens avec le pays d'origine, l'indépendance financière des mosquées ou les questions relatives aux revendications religieuses ou culturelles de l'identité musulmane. A partir de la réalité musulmane, ce livre expose toute l'ambiguïté de nos sociétés « tolérantes » et « ouvertes », mais démunies et contradictoires face à l'émergence récente de la pluralité religieuse.

New perspectives in the use of ink evidence in forensic science: Part III: Operational applications and evaluation.

The research reported in this series of article aimed at (1) automating the search of questioned ink specimens in ink reference collections and (2) at evaluating the strength of ink evidence in a transparent and balanced manner. These aims require that ink samples are analysed in an accurate and reproducible way and that they are compared in an objective and automated way. This latter requirement is due to the large number of comparisons that are necessary in both scenarios. A research programme was designed to (a) develop a standard methodology for analysing ink samples in a reproducible way, (b) comparing automatically and objectively ink samples and (c) evaluate the proposed methodology in forensic contexts. This report focuses on the last of the three stages of the research programme. The calibration and acquisition process and the mathematical comparison algorithms were described in previous papers [C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part I: Development of a quality assurance process for forensic ink analysis by HPTLC, Forensic Sci. Int. 185 (2009) 29-37; C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part II: Development and testing of mathematical algorithms for the automatic comparison of ink samples analysed by HPTLC, Forensic Sci. Int. 185 (2009) 38-50]. In this paper, the benefits and challenges of the proposed concepts are tested in two forensic contexts: (1) ink identification and (2) ink evidential value assessment. The results show that different algorithms are better suited for different tasks. This research shows that it is possible to build digital ink libraries using the most commonly used ink analytical technique, i.e. high-performance thin layer chromatography, despite its reputation of lacking reproducibility. More importantly, it is possible to assign evidential value to ink evidence in a transparent way using a probabilistic model. It is therefore possible to move away from the traditional subjective approach, which is entirely based on experts' opinion, and which is usually not very informative. While there is room for the improvement, this report demonstrates the significant gains obtained over the traditional subjective approach for the search of ink specimens in ink databases, and the interpretation of their evidential value.
