Background: Chronic cluster headache (CH) is a debilitating disorder for which few well-controlled studies demonstrate effectiveness of available therapies. Non-invasive vagus nerve stimulation (nVNS) was examined as adjunctive prophylactic treatment of chronic CH. Methods: PREVA was a prospective, open-label, randomised study that compared adjunctive prophylactic nVNS (n=48) with standard of care (SoC) alone (control (n=49)). A two-week baseline phase was followed by a four-week randomised phase (SoC plus nVNS vs control) and a four-week extension phase (SoC plus nVNS). The primary end point was the reduction in the mean number of CH attacks per week. Response rate, abortive medication use and safety tolerability were also assessed. Results: During the randomised phase, individuals in the intent-to-treat population treated with SoC plus nVNS (n=45) had a significantly greater reduction in the number of attacks per week vs controls (n=48) (-5.9 vs -2.1, respectively) for a mean therapeutic gain of 3.9 fewer attacks per week (95% CI: 0.5, 7.2; p=0.02). Higher #50% response rates were also observed with SoC plus nVNS (40% (18/45)) vs controls (8.3% (4/48); p<0.001). No serious treatment-related adverse events occurred. Conclusion: Adjunctive prophylactic nVNS is a well-tolerated novel treatment for chronic CH, offering clinical benefits beyond those with SoC. [less ▲]

Malgré les recherches sur le système d’information comptable dans les PME, les résultats trouvés sont mitigés et contradictoires. Ainsi, nous essayons à travers ce travail de contribuer au débat relatif au design du système d’information comptable dans les PMI des pays en voie de développement comme la Tunisie. En effet, le système d'information comptable, considéré comme un facteur de compétitivité des entreprises, fournit aux gestionnaires l'information comptable pertinente pour les aider dans leur prise de décision. Nous nous intéressons à une série de facteurs structurels et comportementaux susceptibles de mieux cerner le design du système d’information comptable. Une étude empirique menée par l'adoption de la technique du questionnaire auprès de 221 entreprises tunisiennes opérant exclusivement dans le secteur industriel montre que le design du système d'information comptable est influencé par plusieurs facteurs contextuels, en utilisant les méthodes des équations structurelles.

Aims: To establish a common Key Performance Indicators (KPIs) framework for reporting about the gypsum industry biodiversity at the European level. Methods: In order to integrate different opinions and to reach a consensus framework, an original participatory process approach has been developed among different stakeholder groups: Eurogypsum, European and regional authorities, universities scientists, consulting offices, European and regional associations for the conservation of nature and the extractive industry. The strategy is developed around four main steps: (i) building of a maximum set of indicators to be submitted to stakeholders based on the literature (Focus Group method); (ii) evaluating the consensus about indicators through a policy Delphi survey aiming at the prioritization of indicator classes using the Analytic Hierarchy Process method (AHP) and of individual indicators; (iii) testing acceptability and feasibility through analysis of Environmental Impact Assessments (EIAs) and visits to three European quarries; (iv) Eurogypsum final decision and communication. Results: The resulting framework contains a set of 11 indicators considered the most suitable for all the stakeholders. Conclusions: Our KPIs respond to European legislation and strategies for biodiversity. The framework aims at improving sustainability in quarries and at helping to manage biodiversity as well as to allow the creation of coherent reporting systems. The final goal is to allow for the definition of the actual biodiversity status of gypsum quarries and allow for enhancing it. The framework is adaptable to the local context of each gypsum quarry.

Large changes in the state and seasonality of sea ice are expected for this century in both hemispheres. The impact of these changes on marine biogeochemical cycles and ecosystems is difficult to predict. Will the polar oceans be more or less biologically productive? Will they take up more or less carbon? At this stage, the answers to these key questions are not obvious. Marine biogeochemical cycles in the sea ice zone are characterized by specific processes that have been unravelled over the last 20 years or so. They involve active biological and chemical processes within the sea ice, the modulation of heat and gas exchanges by the ice cover; and the impact of growing and melting sea ice on the water column stratification and vertical exchanges in the water. To understand how sea ice influences marine biogeochemical cycles, the sea ice biogeochemical community focuses on: (i) the synthesis of existing data and the interpretation of robust large-scale patterns; (ii) the introduction of new representations of sea ice processes into large-scale models of the Earth System and the study of their impact; (iii) the evaluation of existing observation methods and the development of new ones. In this talk, I will review and synthesize recent research activities in these lines of thought. [less ▲]

Objective: This review examines stress and its consequences on attention and working memory, stress symptoms in parents of child cancer patients and survivors and long term consequences of stress on cognitive processing in parents of child cancer survivors. Method: Eligible studies were experimental, meta-analyses and qualitative (2000–2013) from Pubmed, Medline, the Cochrane Library, PsycArticles and Google Scholar. Results: We identified 92 eligible papers. They showed that elevated stress can impede performances on tasks requiring attention and memory patterns. In paediatric oncology, parental stress increased shortly after diagnosis involving depression and anxiety. Consequences of stress on cognitive performances were observed mainly among depressed individuals. As regards parents of child cancer survivors, female gender, low SES, innate traits of anxiety/anger predicted the development of PTSS. Conclusion: Evidence of stress on attention and working memory processes in parents of child cancer survivors is insufficient developed. [less ▲]

Firing rate is an important means of encoding information in the nervous system. To reliably encode a wide range of signals, neurons need to achieve a broad range of firing frequencies and to move smoothly between low and high firing rates. This can be achieved with specific ionic currents, such as A-type potassium currents, which can linearize the frequency-input current curve. By applying recently developed mathematical tools to a number of biophysical neuron models, we show how currents that are classically thought to permit low firing rates can paradoxically cause a jump to a high minimum firing rate when expressed at higher levels. Consequently, achieving and maintaining a low firing rate is surprisingly difficult and fragile in a biological context. This difficulty can be overcome via interactions between multiple currents, implying a need for ion channel degeneracy in the tuning of neuronal properties. [less ▲]

This study aimed to investigate the relationship between the history of low back pain and quality of lumbopelvic motor control in soccer players. Forty-three male elite soccer players (mean age, 18.2 ± 1.4 years) filled in questionnaires related to low back pain and attended a session to assess lumbopelvic motor control by means of five tests (the bent knee fall out test, the knee lift abdominal test, the sitting knee extension test, the waiter ’ s bow and the transversus abdominis test). A physiotherapist, blinded to the medical history of the participants, scored (0 = failed, 1 = correct) the performance of the players for each of the tests resulting in a lumbopelvic motor control score ranging from 0 to 5. Forty-seven per cent of the soccer players reported a disabling low back pain episode lasting at least two consecutive days in the previous year. These players scored worse lumbopelvic motor control than players without a history of low back pain (lumbopelvic motor control score of 1.8 vs. 3.3, P < 0.01). The between-groups difference was particularly marked for the bent knee fall out test, the knee lift abdominal test and the transversus abdominis test (P < 0.01). In conclusion, most soccer players with a history of low back pain had an altered lumbopelvic motor control. Further research should examine whether lumbopelvic motor control is etiologically involved in low back pain episodes in soccer players. [less ▲]

Introduction: Les tendinopathies sont des pathologies d’hyperutilisation essentiellement présentent chez les sportifs ainsi que les travailleurs manuels. Elles représentent près de 20% des troubles musculo-squelettiques et plus de 30% des consultations en médecine générale et en médecine sportive. Ces tendinopathies peuvent être rebelles aux traitements conservateurs, raison pour laquelle de nouveaux traitements sont développés parmi lesquels figurent les infiltrations de plasma riche en plaquettes (PRP). L’objectif de notre étude est d’évaluer l’effet d’une injection de PRP suivie d’un protocole de rééducation standardisé chez des patients présentant différentes tendinopathies : épicondylites, tendinopathies du moyen glutéus, patellaires, calcanéennes et fasciites plantaires. Enfin, nous souhaitons mettre en évidence des facteurs biologiques de bon pronostic suite à un traitement par PRP. Matériels et méthodes : 51 patients atteints de différentes tendinopathies, réfractaires aux traitements de kinésithérapie classique depuis au moins 3 mois, ont reçu une injection de PRP sous contrôle échographique sans anesthésie locale. Par la suite, ils ont bénéficié d’une rééducation excentrique standardisée. Aux trois temps de l’étude (pré-injection, 6 semaines et 12 semaines), ils ont reçu une évaluation algo-fonctionnelle (EVA, PRTEE, HOOS, VISA-P, VISA-A, FAAM) en fonction de la localisation de la tendinopathie et une évaluation de la douleur par un algomètre de pression. Résultats : Les résultats montrent d’une manière générale une amélioration significative de l’EVA (p=0,01) après 3 mois de suivi et une amélioration de l’algomètre de pression entre 6 et 12 semaines (p=0,05). Pour les épicondylites, les améliorations sont significatives pour l’EVA (p=0,017) et le PRTEE (p=0,0036) au terme de l’étude. Les tendinopathies du moyen glutéus, patellaires et les fasciites plantaires montrent également une amélioration clinique mais non significative (nombre de sujets trop faible). Concernant les tendinopathies d’Achille, l’EVA (p<0.001) et le VISA-A (p=0,018) évoluent de manière significative après les 6 premières semaines. Aucune relation n’a été mise en évidence entre l’évolution de l’EVA et de l’algomètre de pression et les paramètres biologiques. Conclusions : Une injection de PRP couplée à un programme de rééducation excentrique présente des effets positifs au niveau de la symptomatologie douloureuse et la fonctionnalité pour les épicondylites et les tendinopathies d’Achille. Malgré l’absence de résultats significatifs, la tendance est à l’amélioration clinique concerne également les tendinopathies du moyen glutéal, patellaires et les fasciites plantaires. [less ▲]

The aim of this paper is to suggest a taxonomy that allows for a systematic description of the functions that can be fulfilled by hieroglyphic signs. Taking as a point of departure the insights of several studies that have been published on the topic since Champollion, we suggest that three key-features – namely, semography, phonemography and autonomy – are needed in order to provide a description of the glottic functions of the ancient Egyptian graphemes. Combining these paradigmatic and syntagmatic features, six core functions can be identified for the hieroglyphic signs: they may behave as pictograms, logograms, phonograms, classifiers, radicograms or interpretants. In a second step, we provide a definition for each function and discuss examples that illustrate the fuzziness between these core semiotic categories. [less ▲]

The aim of this article is to describe the nature of phonological disorders among children with primary language disorders. Because phonological disorders can have different origins, it is important for clinicians to be able to determine the origin of difficulties, in order to adapt treatment accordingly. Following an overview of the development of phonological skills, the psycholinguistic model of Steakhouse and Wells (1997) will be explained. This model contribues to a precise examination of the nature of the difficulties experienced by children with primary language disorders. Finally, two studies that examined speech abilities in children with primary language disorders will be presented to illustrate the importance of an in-depth evaluation of phonological abilities for assessment and treatment planning.

The amount of wind turbines has increased exponentially in Belgium in the last eight years (175 in 2007, 771 in 2015). During this period, especially in the last two years, critics of this energy have become more organised, virulent, and active in delaying or stopping many projects. The landscape impact of wind energy is central to their arguments. We wonder if people’s attitudes towards wind turbines and landscape changed in the last years in Belgium and how they changed. This paper compares public perception of wind energy in two researches about landscape perception. The two studies used slightly different methodologies but with similarities in the designs, allowing some comparisons. The first research (2007‐2009) aimed to study the perceived landscape impact and the social acceptance of wind turbines in Belgium. 1542 Belgians were surveyed about their landscape preferences using a photo‐questionnaire, including some pictures with wind turbines. 75 stakeholders of wind energy projects were also interviewed. The second research (2012‐2014) aimed to examine deeper the landscape preferences among 54 residents in three areas in Wallonia where wind turbines are present, using the previous photographs. During the conduct of the first research, changing attitudes were already observed. People had become more familiar with wind turbines and were less reluctant. The symbolic positive aspect of wind energy was highlighted seven years ago. This view continues. However, people seem more categorical in their viewpoint. All respondents have now been confronted to wind energy, which was not the case seven years ago. Some persons are not against wind farms but their increase in number start to overwhelm them. Others point they get used to the turbines, as long as they are not too many and too close. The huge increase in wind farms in the last seven years has changed the acceptance of wind energy. Some doubts about the real efficiency of this energy also shaped the attitudes. [less ▲]
