Published: May 2015

Background
Despite the potential and interest of using technology for delivering specialized psychiatric services to young adults, surprisingly limited attention has been paid to systematically assess their perspectives in this regard. For example, limited knowledge exists on the extent to which young people receiving specialized services for a first-episode psychosis (FEP) are receptive to using new technologies as part of mental health care, and to which types of technology-enabled mental health interventions they are amenable to.

Objective
The purpose of this study is to assess the interest of young adults with FEP in using technology to receive mental health information, services, and supports.

Methods
This study uses a cross-sectional, descriptive survey design. A convenience sample of 67 participants between the ages of 18 and 35 were recruited from two specialized early intervention programs for psychosis. Interviewer-administered surveys were conducted between December 2013 and October 2014. Descriptive statistics are reported.

Results
Among the 67 respondents who completed the survey, the majority (85%, 57/67) agreed or strongly agreed with YouTube as a platform for mental health-related services and supports. The top five technology-enabled services that participants were amenable to were (1) information on medication (96%, 64/67); (2) information on education, career, and employment (93%, 62/67); (3) decision-making tools pertaining to treatment and recovery (93%, 62/67); (4) reminders for appointments via text messaging (93%, 62/67); and (5) information about mental health, psychosis, and recovery in general (91%, 61/67). The top self-reported barriers to seeking mental health information online were lack of knowledge on how to perform an Internet search (31%, 21/67) and the way information is presented online (27%, 18/67). Two thirds (67%; 45/67) reported being comfortable in online settings, and almost half (48%; 32/67) reported a preference for mixed formats when viewing mental health information online (eg, text, video, visual graphics).

Conclusions
Young people diagnosed with FEP express interest in using the Internet, social media, and mobile technologies for receiving mental health-related services. Increasing the awareness of young people in relation to various forms of technology-enabled mental health care warrants further attention. A consideration for future research is to obtain more in-depth knowledge on young people’s perspectives, which can help improve the design, development, and implementation of integrated technological health innovations within the delivery of specialized mental health care.

AbstractA field investigation of iceberg drift pattern and drift speed was conducted in September 2011 in Baffin Bay, northwest Greenland. Ten icebergs were equipped with GPS transponders during a field campaign. Above-waterline dimensions (length, width and height) of the icebergs were measured using a GPS/pressure altimeter and geometrically rectified digital photographs taken during the field campaign. Iceberg lengths, masses and drafts ranged from 95 to 450 m, 330 000 to 17 000 000 t and 70 to 260 m, respectively. The drift patterns and speeds were determined on the basis of GPS positions logged continuously at 1 hour intervals. The drift patterns differed significantly from iceberg to iceberg. The GPS signal was lost on six of the icebergs within the first 23 days of logging. Three transponders were transferring data for more than 5 months until the battery ran out of power. One transponder was sending data until summer 2012. The measured maximum drift speed was 68 cm s−1 (2.4 km h−1), and the mean drift speed for all ten icebergs was 10 cm s−1 (0.4 km h−1). Relations between iceberg size and drift speed were investigated, showing that icebergs with large surface areas moved at the highest speeds, which occurred particularly during strong wind conditions.
Vers la nécessité de repenser la « Grande Europe »
Authors: Saint-Ouen François 
Published: May 2015

Les relations entre l’Union européenne et la Russie, dans un contexte d’évolution du monde globalisé vers les BRICS et de réorientation des flux économiques vers l’Asie, conduisent à nouveau à réfléchir à l’idée de « Grande Europe », aujourd’hui oubliée. Cette idée est analysée non seulement sous l’angle des défis globaux, mais aussi suivant des paramètres historico-culturels, institutionnels, économiques, sécuritaires et sociétaux. L’article montre la persistance, dans certains esprits et dans certaines institutions comme l’OTAN, d’une logique de confrontation. Il estime que cette situation est aujourd’hui de plus en plus dommageable, tant pour l’UE que pour la Russie, mais également pour les pays du partenariat oriental et même pour les pays candidats. Il plaide, à l’inverse, pour des relations économiques entre l’UE et l’Union eurasiatique, ainsi que pour un dialogue politique et sécuritaire totalement repensé, notamment à travers l’OSCE, dans l’objectif d’une Europe plus autonome à l’égard des États-Unis et de l’OTAN.
Is the EU’s failed relationship with Russia the member states’ fault?
Authors: Schmidt-Felzmann Anke 
Published: May 2015

L’année 2014 a vu une rapide et sérieuse détérioration des relations entre l’Europe et la Russie. La soudaine dégradation du « partenariat stratégique » a pris de nombreux observateurs par surprise. Cet article étudie les raisons de l’échec de l’Union européenne à développer des relations de coopération mutuellement bénéficiaires avec la Russie. Il s’intéresse en particulier à l’idée selon laquelle ce sont les divisions internes de l’UE et les liens bilatéraux spécifiques de certains États membres avec la Russie qui sont à l’origine des difficultés de l’Union européenne dans son ensemble. L’article démontre que, si le manque d’unité de l’Union européenne est bien un facteur qui a contribué à l’échec, il ne peut pas entièrement expliquer les mauvais résultats de l’UE concernant la Russie. De nombreux facteurs additionnels permettent d’expliquer les lacunes européennes : une confiance (mal placée) dans la capacité du processus de coopération à améliorer les relations ; la crainte bien ancrée d’une confrontation militaire avec la Russie ; les faiblesses liées à la nature spécifique de l’UE comme acteur international ; et, finalement, le peu de crédit accordé au point de vue des petits États membres qui sont les voisins géographiques de la Russie.
L’énergie dans les relations Europe-Russie
Authors: Nigoul Claude 
Published: May 2015

Les événements qui se déroulent en Ukraine depuis la fin de 2013 ont mis en pleine lumière la dépendance énergétique de l’Europe vis-à-vis de la Russie, son principal fournisseur. Jusque-là les Européens s’en accommodaient par une gestion dynamique visant à stabiliser les relations avec leur grand voisin de l’Est grâce à un accord de partenariat ambitieux et à un dialogue organisé dans le secteur énergétique. Après quelques alertes provisoirement réglées, la crise politique intervenue en Ukraine, qui révèle le heurt entre la volonté de Moscou de retrouver son statut de puissance et celle des Washington de s’y opposer, la question des relations énergétiques entre l’Europe, engagée plus ou moins ardemment derrière les États-Unis, et la Russie, se pose avec une acuité renforcée. De quelles alternatives dispose-t-on en Europe pour alléger la dépendance ? Peut-elle prétendre à l’autosuffisance ? Trouver des fournisseurs de substitution crédibles ? Comment la Russie pourrait-elle faire de l’énergie une arme commerciale et politique et se priver d’une clientèle traditionnelle ? Peut-elle envisager de se tourner vers l’Asie ? Quel en serait le prix politique ? Ces questions ne peuvent trouver de réponses sans poser celle d’une vision géopolitique de grande ampleur, qui postule une solution équitable du différend ukrainien, ouvrant sur une coopération maîtrisée au sein d’un ensemble continental de Brest à Vladivostok.
Le faire ensemble et avec soi-même. Deux contextes superposés
Authors: Puget Janine 
Published: May 2015

Nous proposons une métapsychologie du Lien, du Deux, qui dépend des pratiques issues du « faire entre deux ou plusieurs sujets », ceux-ci étant dotés d’altérité et d’étrangéité irréductibles à ce qui ne correspond pas à ce qui est de l’ordre des mouvements identificatoires. Les conflits proviennent de la manière de gérer la différence radicale, le vide inhérent à l’entre-deux, les relations de pouvoir. Il s’agit alors de reconnaître les difficultés issues de deux contextes de production subjective qui se superposent. Il devient nécessaire d’introduire un vocabulaire spécifique pour reconnaître les conflits propres à chaque espace. Un court exemple clinique permet de suivre les alternatives de ces hypothèses et des interventions possibles.
Narcissisme primaire, narcissisme secondaire. L’identité dans la gestion de la culpabilité meurtrière
Authors: Chan Jenny 
Published: May 2015

Penser l’identité suppose d’interroger les complexes des origines, les fantasmes originaires et les pulsions sexuelles. Pour certains sujets, la scène primitive est inaccessible et la castration conduit à une fixation. Dans cette situation, le fantasme de séduction ne peut qu’être traumatique et entraîne le fantasme Un enfant est battu . En 1915, Freud propose de penser que le moi est investi originairement et pulsionnellement et capable, en partie, de satisfaire ses pulsions sur lui-même. Il appelle cet état le narcissisme et celui de la satisfaction, l’autoérotisme. Lorsque le système d’autosatisfaction est mis en échec, la blessure narcissique rend difficile l’identité. À partir de l’analyse d’une séance de travail dans un groupe de paroles en milieu carcéral, j’interrogerai ces enjeux narcissiques mettant en impasse le développement du sexuel et de l’identité. Derrière le délit, retrouvons-nous ce criminel de la conscience de culpabilité tel que le décrit Freud ?
L’identité sexuée, le sexuel et le genre dans une perspective psychanalytique du lien et de la relation
Authors: Benghozi Pierre 
Published: May 2015

Dans cet article nous proposons une définition différentiée entre le sexué, le sexuel et le genre. Nous en formulons une relecture sémiotique et dans une perspective psychanalytique des liens, telle que l’a développé René Kaës, ces notions qui ne cessent d’interpeller la question identitaire. La psychanalyse de groupe nous permet de penser l’identité dans une référence psychanalytique. En référence à notre conceptualisation du maillage des liens, notre approche sera structurée par une différenciation entre la notion de lien et celle de relation. Notre hypothèse est que : le sexué est au lien ce que le sexuel est à la relation. Le genre étant l’expression sociale et culturelle du sexué et du sexuel. Nous en distinguerons la notion de « sexual » décrite par Jean Laplanche. La clinique du sexué n’est pas la clinique du sexuel, ou du genre. Nous illustrerons à partir de problématiques, telle que « l’énigme transsexuelle », l’attaque du féminin comme attaque contre les liens et les contenants identitaires, la différence de genre dans la société polynésienne, par l’inscription doublement sexuée du lien dans la société kanake en Nouvelle-Calédonie. Nous concluons par une éthique clinique d’une écoute de la différence.
Mise en groupe, psychose et porosité des enveloppes psychiques
Authors: Vollon Clarisse , Gimenez Guy , Bonnet Christian 
Published: May 2015

Nous proposons d’étudier les processus psychiques du thérapeute durant la période de mise en groupe dans le cadre d’un groupe psychanalytique de paroles mené dans un service d’ergo-sociothérapie avec des patients psychotiques adultes. Le but est de montrer que les premiers temps d’un groupe thérapeutique ont pour effet de modifier la texture des enveloppes psychiques du clinicien, qui vont tendre vers une plus grande porosité. Après avoir défini ce que nous entendons par « porosité des enveloppes psychiques », nous présenterons la façon dont nous envisageons la position psychique du thérapeute en situation de groupe, puis nous reviendrons sur les deux premières séances du groupe psychanalytique de paroles. Les résultats de notre recherche nous permettront d’aller plus loin dans la définition du positionnement psychique du thérapeute en situation de groupe, de son cadre interne et de sa position dite « méta ».
Healthcare provider and patient perspectives on diagnostic imaging investigations
Authors: Makanjee Chandra R. , Bergh Anne-Marie , Hoffmann Willem A. 
Published: May 2015

Background: Much has been written about the patient-centred approach in doctor–patient consultations. Little is known about interactions and communication processes regarding healthcare providers’ and patients’ perspectives on expectations and experiences of diagnostic imaging investigations within the medical encounter. Patients journey through the health system from the point of referral to the imaging investigation itself and then to the post-imaging consultation.Aim and setting: To explore healthcare provider and patient perspectives on interaction and communication processes during diagnostic imaging investigations as part of their clinical journey through a healthcare complex.Methods: A qualitative study was conducted, with two phases of data collection. Twenty-four patients were conveniently selected at a public district hospital complex and were followed throughout their journey in the hospital system, from admission to discharge. The second phase entailed focus group interviews conducted with providers in the district hospital and adjacent academic hospital (medical officers and family physicians, nurses, radiographers, radiology consultants and registrars).Results: Two main themes guided our analysis: (1) provider perspectives; and (2) patient dispositions and reactions. Golden threads that cut across these themes are interactions and communication processes in the context of expectations, experiences of the imaging investigations and the outcomes thereof.Conclusion: Insights from this study provide a better understanding of the complexity of the processes and interactions between providers and patients during the imaging investigations conducted as part of their clinical pathway. The interactions and communication processes are provider–patient centred when a referral for a diagnostic imaging investigation is included.

We show that T can be written as a product of two positive contractions if and only if T is of the formfor some a, b ∊ [0, 1] and strictly positive operator P with . Also, we give a necessary condition for a bounded linear operator T with operator matrix on H⊕K that can be written as a product of two positive contractions.
Planning Oral Health and Clinical Discharge in Primary Care: The Comprehensive Dental Care Protocol Outcome
Authors: Cavalcanti Yuri Wanderley , de Almeida Leopoldina de Fátima Dantas , de Souza Barbosa Ailma , Padilha Wilton Wilney Nascimento 
Published: May 2015

ABSTRACT

Introduction
The dental care must be driven by preventive and curative measures that can contribute to the population's oral health promotion.

Objective
To evaluate the impact of the actions proposed by a comprehensive dental care protocol (CDCP) on the oral health condition of primary care users.

Materials and methods
The sample consisted of 32 volunteers, assisted throughout the six phases proposed by the CDCP: diagnosis of dental needs; resolution of urgencies; restorative interventions; application of promotional measures; evaluation of the achieved health level; and periodic controls. Data were collected through clinical exams, which measured the simplified oral hygiene index (OHI-S), gingival bleeding index (GBI) and the decayed, missing and filled teeth (DMFT) Index, before and after the CDCP was implemented. Statistical analysis consisted of the Wilcoxon test, at 5% significance level (α = 0.05).

Results
The OHI-S and GBI indices showed a significant reduction (p < 0.05) from the initial (1.4 ± 0.6 and 46.3 ± 19.9) to final condition (0.9 ± 0.3 and 21.5 ± 7.5). The decayed, missing and filled teeth and the missing teeth component were not significantly altered (p > 0.05), showing final values equal to 12.7 ± 9.6 and 5.6 ± 7.8, respectively. Decayed elements were fully converted into filled elements, and the final values of the decayed and filled elements were, respectively, 0.0 ± 0.0 and 7.3 ± 5.7 (p < 0.05).

Conclusions
The enactment of the CDCP had a beneficial effect on the oral health of the population assisted by the dental services offered in primary care and this protocol seems to fit the public dental service demands.

Clinical significance
The CDCP can be useful to public dental service planning since it showed an efficient clinical outcome to the patients. We consider that this protocol should be employed in primary care oral health services in order to achieve overall upgrade, access enlargement and public oral health promotion.

Evaluation of the Influence of Three different Temperatures on Microleakage of Two Self-etch and One Total-etch Adhesives
Authors: Akbarian Sahar , Sharafeddin Farahnaz , Akbarian Golsa 
Published: May 2015

ABSTRACT

Aim
To evaluate the bonding temperature effect on dentinrestoration microleakage.
The null hypothesis of the study is that the score of microleakage is identical among different adhesive bondings at different temperatures.

Materials and methods
Ninety caries free maxillary premolars were selected. Class V cavities were prepared on the cemento enamel junction (CEJ) of the buccal sides with enamel margins on occlusal sides and cementum margins on gingival sides. The specimens were divided into 3 groups: G1, single bond adhesive + Z250 composite; G2, P90 adhesive + Filtek Silorane composite; and G3, Clearfil SE bond + Clearfil APX. All groups were divided into three subgroups based on the adhesive temperature: A—4°C; B—25°C; and C—40°C. After coating the specimens with nail polish 1 mm beyond the margin of the restorations, they were stored in 0.5% basic Fuchsin dye solution for 24 hours. The teeth then were buccolingually sectioned and observed under a stereomicroscope.

Results
There was no significant difference between microleakage of occlusal and gingival margins in each group. Clearfil SE bond and Adper single bond displayed lower microleakage than P90 adhesive at 4°C and 25°C. The most and least microleakage score for Adper single bond was at 40°C and 25°C respectively. Clearfil SE bond showed less microleakage at 25°C than 4°C and 40°C.

Conclusion
Clearfil SE bond and Adper single bond displayed less microleakage at 25°C while there was no significant difference among for P90 adhesive microleakage at three temperatures.

Evaluation of Different Irrigating Solutions on Smear Layer Removal of Primary Root Dentin
Authors: Balto Hanan , Salama Fouad , Al-Mofareh Sultan , Al-Yahya Faisal 
Published: May 2015

ABSTRACT

Aim
To evaluate the efficacy of ethanolic extract of Salvadora persica (S. persica) and BioPure MTAD (a mixture of a tetracycline isomer, an acid, and a detergent) in removing the intracanal smear layer of primary teeth.

Materials and methods
The root canal of 40 extracted human primary anterior teeth were cleaned, shaped and grouped into experimental (n = 30) and control (n = 10). The root canals of the positive (n = 5) and the negative control (n = 5) were irrigated for 3 minutes with 5 ml of 17% ethylenediaminetetraacetic acid (EDTA) or saline respectively. The canals in the experimental groups were irrigated for 3 minutes with 5 ml of 1 mg/ml ethanolic extract of S. persica (n = 15) or BioPure MTAD (n = 15) and then flushed with 2 ml of saline. The presence or absence of smear layer at the coronal and middle portion of each canal were examined under a scanning electron microscope (SEM).

Results
A significant d ifference (p = 0 .004) i n s mear l ayer removal between S. persica and MTAD at the middle third of the canal was observed. MTAD solution was as effective as 17% EDTA in removing the smear layer.

Conclusion
MTAD was significantly more effective in smear layer removal than S. persica solution at the middle third of the canal wall.

Clinical significance
Both tested irrigant solutions have the ability to remove the intracanal smear from primary root dentin following cleaning and shaping of the root canal and could be an alternative to EDTA.

Authors: Borges Alvaro Henrique , Bandéca Matheus Coelho , de Araújo Estrela Cyntia Rodrigues , Amezcua Octávio , Gonzalez Álvaro Cruz , Estrela Carlos 
Published: May 2015

ABSTRACT

Background
The aim of this research was to compare the apical sealing ability of different root-end filling materials (Super EBA®, ProRoot MTA®, thermoplasticized gutta-percha + AHPlus®, thermoplasticized RealSeal®), by means of microbial indicators.

Materials and methods
Thus, 50 human single-rooted teeth were employed, which were shaped until size 50, retro-prepared with ultrasonic tips and assigned to 4 groups, retro-filled with each material or controls. A platform was employed, which was split in two halves: upper chamber—where the microbial suspension containing the biological indicators was introduced (E. faecalis + S. aureus + P. aeruginosa + B. subtilis + C. albicans); and a lower chamber containing the culture medium brain, heart infusion, where 3 mm of the apical region of teeth were kept immersed. Lectures were made daily for 60 days, using the turbidity of the culture medium as indicative of microbial contamination. Statistical analyses were carried out at 5% level of significance.

Results
The results showed microbial leakage at least in some specimens in all of the groups. RealSeal® has more microbial leakage, statistically significant, compared to ProRoot® MTA and SuperEBA®. No significant differences were observed when compared ProRoot® MTA and SuperEBA®. The guttapercha + AH Plus results showed no statistically significant differences when compared with the other groups.

Conclusions
All the tested materials showed microbial leakage. Root-end fillings with Super-EBA or MTA had the lowest bacterial filtration and RealSeal shows highest bacterial filtration.
