U–Pb Zircon geochronology of the Cambro-Ordovician metagranites and metavolcanic rocks of central and NW Iberia

New U–Pb zircon data from metagranites and metavolcanic rocks of the Schist-Graywacke Complex Domain and the Schistose Domain of Galicia Tras-os-Montes Zone from central and NW Iberia contribute to constrain the timing of the Cambro-Ordovician magmatism from Central Iberian and Galicia Tras-os-Montes Zones which occurred between 498 and 462 Ma. The crystallization ages of the metagranites and metavolcanic rocks from the northern Schist-Graywacke Complex Domain are as follows: (a) in west Salamanca, 489 ± 5 Ma for Vitigudino, 486 ± 6 Ma for Fermoselle and 471 ± 7 Ma for Ledesma; (b) in northern Gredos, 498 ± 4 Ma for Castellanos, 492 ± 4 Ma for San Pelayo and 488 ± 3 Ma for Bercimuelle; (c) in Guadarrama, 490 ± 5 Ma for La Estacion I, 489 ± 9 Ma for La Canada, 484 ± 6 Ma for Vegas de Matute (leucocratic), 483 ± 6 Ma for El Cardoso, 482 ± 8 Ma for La Morcuera, 481 ± 9 Ma for Buitrago de Lozoya, 478 ± 7 Ma for La Hoya, 476 ± 5 Ma for Vegas de Matute (melanocratic), 475 ± 5 Ma for Riaza, 473 ± 8 Ma for La Estacion II and 462 ± 11 Ma for La Berzosa; and (d) in Toledo, 489 ± 7 Ma for Mohares and 480 ± 8 Ma for Polan. The crystallization ages of the metagranites from the Schistose Domain of Galicia Tras-os-Montes Zone are 497 ± 6 Ma for Laxe, 486 ± 8 Ma for San Mamede, 482 ± 7 Ma for Bangueses, 481 ± 5 Ma for Noia, 480 ± 10 for Rial de Sabucedo, 476 ± 9 Ma for Vilanova, 475 ± 6 Ma for Pontevedra, 470 ± 6 Ma for Cherpa and 462 ± 8 Ma for Bande.This magmatism is characterized by an average isotopic composition of (87Sr/86Sr)485Ma ≈ 0.712, (eNd)485Ma ≈ -4.1 and (TDM) ≈ 1.62 Ga, and a high zircon inheritance, composed of Ediacaran–Early Cambrian (65 %) and, to a lesser extent, Cryogenian, Tonian, Mesoproterozoic, Orosirian and Archean pre-magmatic cores. Combining our geochronological and isotopic data with others of similar rocks from the European Variscan Belt, it may be deduced that Cambro-Ordovician magmas from this belt were mainly generated by partial melting of Ediacaran–Early Cambrian igneous rocks

Evaluation des futurs enseignants des SVT du Centre Régional des Métiers de l'Education et de la Formation de Meknès en formation pratique : Réalité et perspectives

The training of the future teachers is based on the articulation between two spaces : Regional Center of theProfession of Education and Training "CRMEF" and the establishment of practice. The practical is concretizedby professional situations called "PSM" where the future teachers are supervised by educational actors.Training presents a prime opportunity to expand the knowledge base and skill development of all futureteachers. Most training will give the future teachers a greater understanding of their responsibilities within theirrole, and in turn build their confidence. through training opportunities. This paper presents the findings of aresearch study conducted in the CRMEF Meknès based on the evaluation the skill development of the full samplesize of 60 surveys future teachers in "PSM".The used methodology is based on assessment grid addressed to 15 educational actors who take care of thesupervision of these future teachers in many schools in Meknes city. The results of our study revealed problemsby the future teachers at "PSM". In conclusion, recommendations were developed for all the actors who areinterested in the training of future teachers.La formation des futurs enseignants est fondée sur l'articulation entre deux espaces : Centre Régional desMétiers de l'Education et de la Formation "CRMEF" et l'établissement de pratique. La connotation pratique estconcrétisée par des mises en situations professionnelles dites "MSP" où les futurs enseignants sont encadrés pardes acteurs pédagogiques. La formation a pour principale vocation d'en permettre le développement desconnaissances et des compétences nécessaires à l’exercice de la profession.Cette étude présente les résultats d’une recherche effectuée en 2016 portant sur l'évaluation du transfert descompétences lors des MSP de 60 futurs enseignants des Sciences de la Vie et de la Terre "SVT" du cyclesecondaire au CRMEF de Meknès. L'évaluation a été assurée par 15 acteurs pédagogiques qui veillent surl'encadrement de ces futurs enseignants. Pour apprécier la production des futurs enseignants la recherche estoutillée par des grilles d’observation qui explicitent les critères d’évaluation qui servent à évaluer la productionet contient une description des niveaux de performance possibles ou attendus de la part de la population cible.Les résultats ont fait état des difficultés éprouvées par les futurs enseignants lors des MSP telles qu'elles sontperçues par les acteurs pédagogiques. Pour remédier à certaines difficultés nous avons essayé d’apporter uneréponse et d'envisager des perspectives

Cognitive Behavioral Therapy in a Group of Militaries With Posttraumatic Stress Disorder

IntroductionPosttraumatic stress disorder (PTSD) has a high prevalence and severe impact in military populations. Cognitive behavioral therapy (CBT) is indicated in this condition but it is a structured therapy that requires patients’ motivation and doctors’ availability.Objectives and aimsAssess feasibility and effectiveness of CBT in a military group with PTSD.MethodsA group of six militaries that witnessed the same traumatic event (an armed attack) and were diagnosed with PTSD were involved in a structured individual session CBT with one therapist. An assessment using the PTSD checklist for DSM (PCL) was performed initially and in halfway therapy. The therapy included an education about PTSD, a cognitive restructuring, a behavioral approach via home tasks and relaxation techniques.ResultsThe initial PCL scores varied from 25 to 55. All patients were initially on sick leave. Five patients had adjunctive antidepressant medications and one patient was only on therapy. Three patients showed no motivation and were excluded after 3 sessions. Two patients have had 7 weekly sessions and were able to return to work in the same place. One patient with severe PTSD had 2 sessions monthly, he had slight clinical improvement and could not come back to military work. The three patients who are still in therapy have improved PCL scores.ConclusionsCBT can be effective in PTSD. The outcome depends on initial severity of PTSD and assiduity.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec

Post-traumatic Mania Symptoms: About One Case

IntroductionPsychotraumatism can constitute for some people a real existential fracture, a real upheaval of the psychic organization.Immediate psychological reactions can vary from one-off and temporary reactions to far more severe and sometimes enduring reactions.Material and methodsWe collected the case of a patient who was hospitalised in April 2015 for manic symptoms in the immediate aftermath of a terrorist attack, with a review of the literature.Clinical caseThis is Mr. A. F., aged 38, with a personal history of AVP and a shooting wound following a terrorist attack. He had presented a psychomotor instability and an exaltation of the mood in the immediate aftermath of an ambush.Behavioural problems were identified by the psychiatric team during the group debriefing conducted at the HMPIT emergency room. During his hospitalisation, a chemotherapy based on thymoregulators, neuroleptics and anxiolytics was introduced.The evolution was marked by a significant regression of the manic syndrome after ten days, and the installation of a post-traumatic stress condition (PTSD). At the end of eight months, the patient was able to resume his work with long-term thymoregulatory treatment, a ban on weapons and safety posts.ConclusionManic episodes are rarely observed as an immediate post-traumatic reaction. Their occurrence does not prevent the subsequent installation of PTSD. Has psychic trauma revealed a latent psychosis? Is it a trauma-induced mood disorder?Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec

Psychiatric causes of unfitness for military service

IntroductionThe national service is a duty for every Tunisian citizen. The knowledge of psychiatric causes of unfitness for military service would enable developing standardized procedures for selecting and psychiatric assessment of young candidates.ObjectivesDetermination of the diagnostic categories, frequency and factors associated with psychiatric causes of unfitness for military service.MethodThis was a retrospective, descriptive study, performed on medical files of candidates examined between the 1st of January and the 31st of December 2015 at the military hospital of Tunis.ResultsEight hundred and seventy-two subjects were examined as a part of an assessment for mental fitness for military service. They were male, single, with an average age of 23.73 ± 3.5 years. Alcohol was consumed by 17.9% of subjects, cannabis by 12.8% and psychotropic by 4.7%. Fourteen percent had self-mutilation, 8.5% had criminal record and 5.3% had tattoos. Military unfitness was found in 80.8% of cases. The main causes of unfitness were anti-social personality disorder (40.6%), hysterical neurosis (14.9%), adjustment disorders (14.5%) and limited intellectual level (7.5%). The average length of service before found unfit was 9.14 months for anti-social personality, 5.94 months for adjustment disorders and 1.78 months for psychotic disorders. This period was significantly longer for the personality disorders (8.62 months) compared to psychotic disorders (P = 0.013) or to non-psychotic disorders (5.05 months, P &lt; 0.001).ConclusionThe evaluation on the mental ability of military personnel must be performed at an early date, given the financial, material and human consequences that would result from a delayed diagnosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec

Tobacco cessation failure: Predictive value of BDI score

BackgroundSmoking is a major healthcare issue. Evidence shows considerable comorbidity between nicotine dependence and depressive disorders.ObjectivesWe are interested in the correlation between Beck's depression inventory (BDI) scores and smoking cessation outcomes.MethodsRetrospective, transversal and analytical study. Data were collected from 95 patients followed in the smoking cessation consultation of The military hospital of Tunis. The BDI was used to assess depressive symptoms and nicotine dependence evaluated by Fagerstrom test for nicotine dependence (FTND).ResultsPopulation was composed of men (92%), married in 65% of cases, with a mean age of 45 ± 13 years. The mean age of smoking initiation was 18 ± 4.5 years. Regular smoking average was 37 ± 20 Packs/Year. The mean cigarette consumption was 30 ± 15 per day. Forty-two percent patients reported at least one attempt to quit smoking, with an average of 37.26 days of abstinence. The mean score of FTND test was 7 ± 2.31. The BDI score was higher than 3 in 86% of cases. Patients with severe depression (BDI &gt; 15) had never attempted a withdrawal in 71% of cases (P = 0.009), had a high or very high dependence in 85.7% of cases (P = 0.016). The average of cigarettes per day was 40 (P = 0.035) and they had failed withdrawal in 79% of cases (P = 0.53).ConclusionThere was a fairly consistent association between presence of depression and smoking severity. This suggests that for individuals with nicotine dependence who are interested in quitting smoking, assessment and treatment of depressive symptoms may improve smoking cessation outcomes.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec
