[Catatonia education in France: A cross-sectional study]. Encephale 2019; 45:391-396.

Abstract
OBJECTIVES Catatonia is a transnosographic syndrome described by K. Kahlbaum in 1874. Catatonia can be life-threatening due to its complications and in case of malignant catatonia. Safe and effective treatments have been identified (benzodiazepines and electro-convulsive-therapy). The prevalence of this syndrome is important and represents about 10% of inpatients in an acute psychiatric ward. However, this syndrome appears to remain under-diagnosed and poorly known. We were, therefore, interested in the current knowledge of French psychiatry residents and young psychiatrists as well as the education they had received about catatonia. METHODS A questionnaire was submitted to French psychiatry residents and young psychiatrists with fewer than 5 years of experience. It included questions about knowledge of the symptoms, complications, causes and treatments of catatonia. Participants were also asked about their confidence in the management of a patient with catatonia and about the number of catatonic patients they had already met. The type of lecture and teaching about catatonia was also assessed. RESULTS Among the 376 psychiatrists that completed the questionnaire, 37.5% never had received any specific teaching about catatonia. Concerning the 62.5% who benefited from a specific lecture, this was mainly delivered as part of psychiatry DES. Heterogeneity in the education delivery on the French territory had been highlighted. In addition, participants' knowledge of catatonic syndrome seems incomplete. However, knowledge of catatonic symptoms and first intention treatments was significantly better among respondents who were part of the "with education" group. The confidence in catatonia recognition and management, as well as the number of catatonic patients they met, are also significantly higher in the group "with education". CONCLUSION Specific education seems to improve the knowledge of young doctors and their ability to diagnose and treat catatonic patients. This education remains poorly provided and heterogeneous on the French territory. Catatonia deserves a place in the teaching program of the psychiatry DES, thus to become systematic.

Depression and obesity, data from a national administrative database study: Geographic evidence for an epidemiological overlap. PLoS One 2019; 14:e0210507. [PMID: 30620759 PMCID: PMC6324832 DOI: 10.1371/journal.pone.0210507] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Accepted: 12/24/2018] [Indexed: 01/05/2023] Open
Abstract
Background Depression and obesity are two major conditions with both psychological and somatic burdens. Some data suggest strong connections between depression and obesity and more particularly associated prevalence of both disorders. However, little is known about the geographical distribution of these two diseases. This study aimed to determine if there is spatial overlap between obesity and depression using data from the entire French territory. Methods Data for 5,627 geographic codes for metropolitan France were collected from the two national hospital databases (PMSI-MCO and RIM-P) for the year 2016. We identified people who were depressed, obese or both registered in the two public medico-administrative databases, and we assessed their location. In addition, a multivariable analysis was performed in order to determine geographic interactions between obesity and depression after controlling for age, sex, environmental and socio-economic factors (social/material deprivation, urbanicity/rurality). Results 1,045,682 people aged 18 years and older were identified. The mapping analysis showed several cold and hot regional clusters of coinciding obesity and depression. The multivariable analysis demonstrated significant geographic interactions, with an increasing probability of finding a high prevalence of obesity in regions with major depression (OR 1.29 95% CI 1.13–1.49, p = 0.0002) and an increased probability of finding a high prevalence of depression in regions with a high ration of obesity (OR 1.32, 95% CI 1.15–1.52, p<0.0001). Conclusion Our study confirms the significant bidirectional relationships between obesity and depression at a group level. French geographic patterns reveal a partial overlap between obesity and depression, suggesting these two diseases can be included in a common approach. Further studies should be done to increase the understanding of this complex comorbidity.

Type A competitiveness traits correlate with downregulation of c-Fos expression in patients with type 1 diabetes. DIABETES & METABOLISM 2018; 45:582-585. [PMID: 30476653 DOI: 10.1016/j.diabet.2018.11.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 11/13/2018] [Accepted: 11/14/2018] [Indexed: 10/27/2022]
Abstract
AIM Type A personality has been associated with increased survival in people with type 1 diabetes (T1D). Systemic low-grade inflammation may play a critical role, as suggested in recent reports, although the links between the inflammatory circulating transcriptome and Type A remain unknown. This prompted our exploration of the potential associations between Type A personality and c-Fos gene expression, a candidate gene closely linked to inflammatory processes, in T1D. METHODS Type A personality was assessed by Bortner questionnaire in patients with T1D, and two subscales - 'speed' and 'competitiveness' - were used to measure these specific dimensions of Type A. Expression of the c-Fos gene was assessed by a quantitative real-time polymerase chain reaction technique. RESULTS This pilot study included 20 men with T1D. Multivariable analyses showed an independent inverse association between Type A competitiveness score and c-Fos expression, while a regression model adjusted for age, body mass index and HbA1c levels revealed a significant inverse relationship between c-Fos transcripts and Type A competitiveness (P = 0.003). CONCLUSION This strong association between Type A competitiveness and reduced c-Fos expression is in line with recent data suggesting a psychobiological influence of the Type A profile in T1D via inflammatory pathways.

Distinct Expression Pattern of Epigenetic Machinery Genes in Blood Leucocytes and Brain Cortex of Depressive Patients. Mol Neurobiol 2018; 56:4697-4707. [PMID: 30377985 PMCID: PMC6647377 DOI: 10.1007/s12035-018-1406-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Accepted: 10/24/2018] [Indexed: 12/25/2022]
Abstract
In major depressive disorder (MDD), altered gene expression in brain cortex and blood leucocytes may be due to aberrant expression of epigenetic machinery coding genes. Here, we explore the expression of these genes both at the central and peripheral levels. Using real-time quantitative PCR technique, we first measured expression levels of genes encoding DNA and histone modifying enzymes in the dorsolateral prefrontal cortex (DLPFC) and cingulate cortex (CC) of MDD patients (n = 24) and healthy controls (n = 12). For each brain structure, transcripts levels were compared between subject groups. In an exploratory analysis, we then compared the candidate gene expressions between a subgroup of MDD patients with psychotic characteristics (n = 13) and the group of healthy subjects (n = 12). Finally, we compared transcript levels of the candidate genes in blood leucocytes between separate samples of MDD patients (n = 17) and healthy controls (n = 16). In brain and blood leucocytes of MDD patients, we identified an overexpression of genes encoding enzymes which transfer repressive transcriptional marks: HDAC4-5-6-8 and DNMT3B in the DLPFC, HDAC2 in the CC and blood leucocytes. In the DLPFC of patients with psychotic characteristics, two genes (KAT2A and UBE2A) were additionally overexpressed suggesting a shift to a more transcriptionally permissive conformation of chromatin. Aberrant activation of epigenetic repressive systems may be involved in MDD pathogenesis both in brain tissue and blood leucocytes.

Abstract
There are 11 million family caregivers in France and some estimates indicate that there will be 17 million in 2020. Caregiving is a source of chronic stress that requires adaptation and coping strategies. Caregiving may benefit the health of a caregiver with a positive coping style and altruistic goals. However, the caregiver's burden is frequently associated with negative effects in terms of biopsychosocial imbalance and medical conditions, with frequent anxiety and depression. The management of the caregiving burden starts with the recognition of health professionals - caregivers may benefit from consultation-liaison psychiatry and multidisciplinary medico-social strategies, in addition to constant support from their GPs.

Abstract
Some studies have reported that repetitive transcranial magnetic stimulation (rTMS) applied to the dorsolateral prefrontal cortex (DLPFC) is able to induce changes in the hypothalamic-pituitary axis in subjects with major depression. The causes of these neuroendocrine effects are unknown and deserve to be studied. The authors monitored neuroendocrine hormones in 15 subjects with major depression treated by 1-Hz rTMS on the right DLPFC and explored a correlation with mood improvement. Unlike previous studies, no changes in serum cortisol, prolactin, and thyroid hormone levels were found. However, the authors did observe short-term changes in growth hormone levels in nonresponsive subjects.

Mast cells' involvement in inflammation pathways linked to depression: evidence in mastocytosis. Mol Psychiatry 2016; 21:1511-1516.

Abstract
Converging sources of evidence point to a role for inflammation in the development of depression, fatigue and cognitive dysfunction. More precisely, the tryptophan (TRP) catabolism is thought to play a major role in inflammation-induced depression. Mastocytosis is a rare disease in which chronic symptoms, including depression, are related to mast cell accumulation and activation. Our objectives were to study the correlations between neuropsychiatric features and the TRP catabolism pathway in mastocytosis in order to demonstrate mast cells' potential involvement in inflammation-induced depression. Fifty-four patients with mastocytosis and a mean age of 50.1 years were enrolled in the study and compared healthy age-matched controls. Depression and stress were evaluated with the Beck Depression Inventory revised and the Perceived Stress Scale. All patients had measurements of TRP, serotonin (5-HT), kynurenine (KYN), indoleamine 2,3-dioxygenase 1 (IDO1) activity (ratio KYN/TRP), kynurenic acid (KA) and quinolinic acid (QA). Patients displayed significantly lower levels of TRP and 5-HT without hypoalbuminemia or malabsorption, higher IDO1 activity, and higher levels of KA and QA, with an imbalance towards the latter. High perceived stress and high depression scores were associated with low TRP and high IDO1 activity. In conclusion, TRP metabolism is altered in mastocytosis and correlates with perceived stress and depression, demonstrating mast cells' involvement in inflammation pathways linked to depression.

Abstract
Cardiovascular events and emotional disorders share a common epidemiology, thus suggesting fundamental pathways linking these different diseases. Growing evidence in the literature highlights the influence of psychological determinants in somatic diseases. A patient's socio-economic aspects, personality traits, health behavior and even biological pathways may contribute to the course of cardiovascular disease. Cardiac events often occur suddenly and the episode can be traumatic for people not prepared for such an event. In this review of the literature, the authors tackle the question of psychobiological mechanisms of stress, in a pathophysiological approach to fundamental pathways linking the brain to the heart. Various psychological, biological and genetic arguments are presented in support of the hypothesis that various etiological mechanisms may be involved. The authors finally deal with biological and psychological strategies in a context of cardiovascular disease. Indeed, in this context, cardiac rehabilitation, with its global approach, seems to be a good time to diagnose emotional disorders like anxiety and depression, and to help people to cope with stressful events. In this field, cardiac rehabilitation seems to be a crucial step in order to improve patients' outcomes, by helping them to understand the influence of psychobiological risk factors, and to build strategies in order to manage daily stress.

Efficacy of transcranial direct current stimulation (tDCS) in reducing consumption in patients with alcohol use disorders: study protocol for a randomized controlled trial. Trials 2016; 17:250. [PMID: 27188795 PMCID: PMC4869375 DOI: 10.1186/s13063-016-1363-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2015] [Accepted: 04/24/2016] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Approximately 15 million persons in the European Union and 10 million persons in the USA are alcohol-dependent. The global burden of disease and injury attributable to alcohol is considerable: worldwide, approximately one in 25 deaths in 2004 was caused by alcohol. At the same time, alcohol use disorders remain seriously undertreated. In this context, alternative or adjunctive therapies such as brain stimulation may play a prominent role. The early results of studies using transcranial direct current stimulation found that stimulations delivered to the dorsolateral prefrontal cortex result in a significant reduction of craving and an improvement of the decision-making processes in various additive disorders. We, therefore, hypothesize that transcranial direct current stimulation can lead to a decrease in alcohol consumption in patients suffering from alcohol use disorders. METHODS/DESIGN We report the protocol of a randomized, double-blind, placebo-controlled, parallel-group trial, to evaluate the efficacy of transcranial direct current stimulation on alcohol reduction in patients with an alcohol use disorder. The study will be conducted in 14 centers in France and Monaco. Altogether, 340 subjects over 18 years of age and diagnosed with an alcohol use disorder will be randomized to receive five consecutive twice-daily sessions of either active or placebo transcranial direct current stimulation. One session consists in delivering a current flow continuously (anode F4; cathode F3) twice for 13 minutes, with treatments separated by a rest interval of 20 min. Efficacy will be evaluated using the change from baseline (alcohol consumption during the 4 weeks before randomization) to 24 weeks in the total alcohol consumption and number of heavy drinking days. Secondary outcome measures will include alcohol craving, clinical and biological improvements, and the effects on mood and quality of life, as well as cognitive and safety assessments, and, for smokers, an assessment of the effects of transcranial direct current stimulation on tobacco consumption. DISCUSSION Several studies have reported a beneficial effect of transcranial direct current stimulation on substance use disorders by reducing craving, impulsivity, and risk-taking behavior, and suggest that transcranial direct current stimulation may be a promising treatment in addiction. However, to date, no studies have included sufficiently large samples and sufficient follow-up to confirm the hypothesis. Results from this large randomized controlled trial will give a better overview of the therapeutic potential of transcranial direct current stimulation in alcohol use disorders.

Abstract
IntroductionLe trouble dépressif majeur (TDM) est associé à des altérations de l’expression génique au niveau cérébral et en périphérie, dans les leucocytes sanguins. Chez les dépressifs, les études de neuroimagerie ont mis en évidence des anomalies structurales et fonctionnelles affectant deux régions clés du réseau frontocingulaire : le cortex préfrontal dorso-latéral (DLPFC) et le cortex cingulaire (CC). Actuellement, les mécanismes moléculaires permettant de faire le lien entre ces différents niveaux étiopathogéniques restent inconnus. Les mécanismes épigénétiques, situés à l’interface entre le génome et la réponse cellulaire, constituent des candidats potentiels.ObjectifExplorer le rôle de l’épigenèse dans le cadre du TDM en phase d’état.Matériel et méthodesNous avons mesuré l’expression de différents gènes impliqués dans les mécanismes épigénétiques dans les leucocytes du sang périphérique, le DLPFC et le CC, chez des patients dépressifs et des sujets contrôles appariés. Les niveaux des différents transcrits ont été mesurés par PCR quantitative en temps réel.RésultatsChez les patients dépressifs, nous avons mis en évidence une surexpression des gènes codant pour des enzymes intervenant dans la mise en place de marques chromatiniennes réprimant la transcription : HDACs 4-5-6-8 et DNMT3B dans le DLPFC, HDAC2 dans le CC et les leucocytes sanguins.ConclusionNos résultats retrouvent une activation des mécanismes épigénétiques réprimant l’expression génique dans le DLPFC et le CC chez les patients dépressifs. Il s’agit de la première fois qu’une telle dérégulation est décrite dans ces deux régions. Ces modifications pourraient participer aux dysfonctionnements affectant le DLPFC et le CC et participer à la physiopathologie du TDM. De plus, nous retrouvons une surexpression de HDAC2 dans les leucocytes sanguins des patients dépressifs, ce qui renforce son statut de potentiel biomarqueur périphérique.

Abstract
BACKGROUND Further evidence suggests that repetitive Transcranial Magnetic Stimulation (rTMS) is an effective method to reduce tobacco craving among smokers. HYPOTHESIS As relapse is common within a few days after smoking cessation, we hypothesized that combining the anti-craving effects of rTMS with Nicotine replacement therapy (NRT) to attenuate withdrawal symptoms could increase abstinence rates in smokers with severe nicotine dependence who quit smoking. METHODS Thirty-seven smokers who failed to quit with the usual treatments were randomly assigned to two treatment groups to receive either active (n = 18) or sham (n = 19) 1-Hz rTMS of the right dorsolateral prefrontal cortex. The day after quitting smoking, each patient combined NRT (21-mg patch) with active or sham rTMS (10 sessions) for 2 weeks. Cessation support was then continued with NRT alone using lower-dose patches. Abstinence rates and self-report craving scales were used to assess the therapeutic results during the combined treatment and for up to 12 weeks after quitting. RESULTS At the end of the combined treatment, there were significantly more abstinent participants in the active rTMS group (n = 16) than in the sham rTMS group (n = 9) (P = 0.027). The craving scales analysis revealed that active rTMS (P = 0.011) but not sham rTMS (P = 0.116) led to a significant decrease in the compulsive factor. However, no lasting rTMS effect was found. CONCLUSIONS 1-Hz rTMS combined with NRT improved the success rate of abstinence in smokers during tobacco cessation. The stimulation-induced reduction in compulsivity may explain this result.

Abstract
A psychotherapeutic approach for schizophrenia is now recommended as an adjuvant for psychopharmacology, since antipsychotic medications only have a partial impact especially as regards positive symptoms and insight. In addition, cognitive distortions and the lack of metacognitive skills might increase positive symptoms leading to poor social functioning. This underlines the need for specific approaches which target cognitive processes relevant for insight, and abilities in metacognition. Metacognitive training (MCT) is a structured group intervention, which enhances a patient's reflection on cognitive biases and improves problem-solving. The aim of our study was to assess MCTs' short term impact on insight, symptoms and quality of life. Fifty patients with schizophrenia or schizoaffective disorders and persistent positive symptoms (delusions or hallucinations) were enrolled in the study. After baseline assessment participants were randomised either to supportive therapy or MCT. Both groups used the same design (1h-session twice a week during 8weeks) although the basic knowledge given to participants was different between interventions. Participants were assessed at eight weeks based on the Scale to Assess Unawareness of Mental Disorder, Positive and Negative Syndrome Scale (PANSS), Psychotic Symptom Rating Scales, the Calgary Depression Scale for Schizophrenia and the Quality of Life Scale. Between-group differences were significant in favour of MCT on the PANSS positive scale. Between-group differences in post- and pre-test values showed a trend in favour of MCT for insight on hallucinations. Results of our study indicate that the MCT has an effect on reducing positive symptomatology, and a trend impact on insight and social functioning.

[PMID: 23917070 DOI: 10.1016/j.bbi.2013.07.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2013] [Revised: 07/04/2013] [Accepted: 07/15/2013] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Mastocytosisis a rare disease associated with chronic symptoms related to mast cell mediator release. Patients with mastocytosis display high level of negative emotionality such as depression and stress sensibility. Brain mast cells are mainly localized in the diencephalon, which is linked to emotion regulatory systems. Negative emotionality has been shown to be associated with telomere shortening. Taken together these observations led us to hypothesize that mast cells activity could be involved in both negative emotionality and telomere shortening in mastocytosis. OBJECTIVE To demonstrate a possible relationship between negative emotionality in mastocytosis and leukocytes telomere length. METHODS Leukocyte telomere length and telomerase activity were measured among mastocytosis patients and were correlated with perceived stress and depression assessed by the Beck Depression Inventory revised and the Perceived Stress Scale. RESULTS Mild-severe depression scores were frequent (78.9%) as well as high perceived stress (42.11%). Telomere length was correlated to perceived stress (r=0.77; p=0.0001) but not to depression in our population. Patients displaying Wild-type KIT significantly presented higher perceived stress levels. Patients with the D816VC KIT mutation who had high perceived stress scores displayed significantly shorter telomere but not if they had high depression scores. CONCLUSION These findings suggest that high perceived stress in mastocytosis could accelerate the rate of leukocytes telomere shortening. Since mastocytosis is, by definition, a mast cell mediated disease; these cells could be involved in this phenomenon. Mechanistic causal relationships between these parameters need to be investigated.

Longitudinal study of alexithymia and multiple sclerosis. Brain Behav 2014; 4:75-82. [PMID: 24653957 PMCID: PMC3937709 DOI: 10.1002/brb3.194] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2013] [Revised: 10/03/2013] [Accepted: 10/27/2013] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVE The aim of this study was to investigate the course of alexithymia and its relation with anxiety and depression in patients with multiple sclerosis (MS), over a period of 5 years. METHODS Sixty-two MS patients were examined at two timepoints, 5 years apart, and they answered questionnaires collecting socio-demographic, medical, and psychological data (depression, anxiety, alexithymia). RESULTS Our data show that emotional disorders remain stable over time in patients with MS, particularly as regards alexithymia and anxiety. Conversely, the rate of depression decreased between the two evaluations, falling from 40% to 26%. The two dimensions of alexithymia (i.e., difficulty describing and difficulty identifying feelings) were correlated with anxiety and depression, whereas the third component of alexithymia (externally oriented thinking) was independent, and was the only component to change over time, with a significant fall observed at 5 years. CONCLUSION Alexithymia was associated with increased severity of anxiety and attack relapses.

Abstract
Background Major depressive disorder (MDD) is frequently associated with chronic medical illness responsible of increased disability and mortality. Inflammation and oxidative stress are considered to be the major mediators of the allostatic load, and has been shown to correlate with telomere erosion in the leucocytes of MDD patients, leading to the model of accelerated aging. However, the significance of telomere length as an exclusive biomarker of aging has been questioned on both methodological and biological grounds. Furthermore, telomeres significantly shorten only in patients with long lasting MDD. Sensitive and dynamic functional biomarkers of aging would be clinically useful to evaluate the somatic impact of MDD. Methodology To address this issue we have measured in the blood leucocytes of MDD patients (N = 17) and controls (N = 16) the expression of two genes identified as robust biomarkers of human aging and telomere dysfunction: p16INK4a and STMN1. We have also quantified the transcripts of genes involved in the repair of oxidative DNA damage at telomeres (OGG1), telomere regulation and elongation (TERT), and in the response to biopsychological stress (FOS and DUSP1). Results The OGG1, p16INK4a, and STMN1 gene were significantly up-regulated (25 to 100%) in the leucocytes of MDD patients. Expression of p16INK4a and STMN1 was directly correlated with anxiety scores in the depression group, and that of p16INK4a, STMN and TERT with the depression and anxiety scores in the combined sample (MDD plus controls). Furthermore, we identified a unique correlative pattern of gene expression in the leucocytes of MDD subjects. Conclusions Expression of p16INK4 and STMN1 is a promising biomarker for future epidemiological assessment of the somatic impact of depressive and anxious symptoms, at both clinical and subclinical level in both depressive patients and general population.

Abstract
BACKGROUND There is a need to increase the recruitment to psychiatry in France. Our aim in this study was to compare factors influencing career choice between French medical students considering and not considering psychiatry as a specialty. SUBJECTS AND METHODS Quantitative cross-sectional online survey on 145 French students in their last year of medical school. RESULTS 22.7% of our sample considered choosing a career in psychiatry. A preference for a career in psychiatry was associated with more frequent history of personal/familial mental illness, higher ratings of psychiatric teaching, more weeks of compulsory psychiatry teaching and placement, during which students had more often met patients in recovery and been asked their opinion on patients. Students considering psychiatry as a career also emphasized more the need for a good work-life balance, and presented better attitudes toward psychiatry. CONCLUSIONS Improving opportunities of interactions between students and psychiatrists or psychiatric patients might help to improve recruitment in psychiatry.

Abstract
Introduction The outcome of cerebral ischemic stroke associated with cannabis use is usually favorable. Here we report the first case of cannabis-related stroke followed by neuropsychiatric sequelae. Case presentation A 24-year-old Caucasian man was discovered in a deeply comatose non-reactive state after cannabis use. A magnetic resonance imaging scan of his brain showed bilateral multiple ischemic infarcts. The patient remained deeply comatose for four days, after which time he developed other behavioral impairments and recurrent seizures. Conclusion Stroke related to cannabis use can be followed by severe neuropsychiatric sequelae. Concomitant alcohol intoxication is essential neither to the occurrence of this neurologic event nor to its severity.

Expression of oxidative stress-response genes is not activated in the prefrontal cortex of patients with depressive disorder. Psychiatry Res 2011; 186:244-7.

Abstract
To test the hypothesis that the oxidative stress consistently detected in the peripheral blood of patients with depressive disorder impacts on the functionally relevant brain region, the expression level of nine major genes of the stress response and repair systems has been quantified in the prefrontal cortex of 24 depressive and 12 control subjects. These genes were: superoxide dismutase (SOD1), SOD2, catalase (CAT), gluthatione peroxidase 1 (GPx1), 8-oxoguanine DNA glycosylase (OGG1), nei-like 1 (NEIL1), methionine sulphoxide reductase A (MSRA), telomere repeat-binding factor 2 (TERF2) and C-FOS. Telomere length (a maker of chronic exposure to oxidative stress) has been measured in the DNA of the occipital cortex. No significant difference has been found between the compared groups. It must be concluded that the pathogenic role of the oxidative stress in the cerebral mechanism of depression cannot be inferred from the alteration of peripheral parameters.

Abstract
AbstractThis article reviews current knowledge of the long-term behavior of R7T7-type glass during the thermal phase and in geological repository conditions (aqueous alteration). In interim storage R7T7 glass can be considered to conserve its integrity over time. In geological repository conditions, the mechanisms of glass alteration by water have been identified and parameter values have been assigned to the reaction kinetics for wide variations of the influential factors (temperature, pH, flow rate, S/V ratio, etc.). CEA has developed an operational model to obtain robust and reasonably conservative predictions of the glass quantities altered after disposal. Examples of applications of the operational model are discussed, future research topics are also proposed to consolidate this approach.

Abstract
Since their introduction, genetic tests have been carefully considered, with special attention to the release of information about the test and test results, the confidentiality of genetic information, the request and its motivation, and the psychological impact of the test. Careful consideration is needed when family members at risk are asymptomatic children or adolescents. Cautious reflection is warranted on whether and under which conditions genetic testing should be performed. Here, we report on the results of a survey conducted in France among 50 geneticists questioned on their opinions and practices concerning presymptomatic testing in three groups of diseases: those for which a medical benefit exists during childhood (e.g., retinoblastoma), diseases with onset during childhood for which there are no immediate medical consequences (e.g., type II/III spinal muscular atrophy), and those with onset during adulthood for which there is no medical benefit during childhood (e.g., Huntington disease). Guidelines are proposed: presymptomatic testing should not be performed in a minor without individual and direct information, all requests for presymptomatic genetic testing concerning a disease with onset in adulthood should be postponed, and all presymptomatic test requests for a minor should be addressed to a multidisciplinary team.

Abstract
OBJECTIVES This study aimed to assess subjective quality of life in patients with multiple sclerosis regarding the criteria of satisfaction and importance attached to various domains of life. METHOD Sixty-one subjects took part in this study. The psychological evaluation consisted of a clinical interview and three questionnaires: subjective quality of life profile (PQVS), State-Trait anxiety inventory (STAI), Beck depression inventory (BDI). RESULTS The results show a low level of general satisfaction of subjective quality of life. Fatigue and pain are the most unsatisfactory domains of life while the relationships with close relations and medical staff are perceived as the most satisfactory and important domains of life. Some differences are observed between men and women regarding the satisfaction of conjugal life and fatigue perception. The subjective quality of life seems mainly correlated to anxiety, depression and to the level of handicap. CONCLUSIONS Our results emphasize the necessity of taking into account the subjective perception of the disease which can lead in an appropriated treatment. These results underline the place of anxious and depressive disorders associated with multiple sclerosis, which seem to have a certain impact on the subjective quality of life.

Abstract
RESULTS This study, inspired by the attachment model and research in the field of social support, attempts to reveal the link between styles of attachment, social support and depressive vulnerability. AIM OF THE STUDY It investigates current styles of attach-ment and the quality of social support perceived by 35 hospitalized, depressed subjects compared to 35 control subjects who exhibited no pathology. After giving their consent, each subject took part in an in-depth psychological investigation consisting of a recorded clinical interview and various clinical scales. METHOD The study presents only the responses to the Perception of Relations questionnaire which distinguishes between four styles of attachment (secure, detached, preoccupied and disorganized) and the Social Support Questionnaire (SSQ6) which contains two dimensions: social availability and social satisfaction. The results were subjected to statistical analyses: a comparative analysis between the two groups and a correlational analysis between the dimensions of social support and the dimensions of style of attachment. On the one hand, the study reveals that the social network is perceived to be less available by depressed subjects, together with the absence of a current intimate relationship with other people, the absence of people to confide in, and a relationship between this absence and the large number of losses experienced by depressed subjects, in particular the loss of figures of attachment (father and mother). On the other hand, depressed subjects tend to exhibit a preoccupied, disorganized style of attachment which is characterized by negative models of the self. DISCUSSION The discussion addresses the way these styles of attachment should be understood: do they represent the consequence of the depressive pathology or an older relational style?

Abstract
INTRODUCTION Post-stroke depression is a severe complication affecting 30-50% of patients during the first year. Experienced medical and paramedical staff in stroke units, using validated scales, can now identify initial signs of depression in the first days after stroke onset. METHODS This review of the literature is based on a Medline search for the terms stroke, depression, and epidemiology. It discusses problems of pathophysiology, diagnosis, prognosis, and therapeutics. RESULTS Depression is an emergency in stroke patients because it impedes rehabilitation and family and social insertion. Early diagnosis is difficult, but possible with clinical somatic and cognitive symptoms. Post-stroke depression may also be a marker of pending cognitive decline. Management requires both antidepressants and psychotherapy. CONCLUSION There is a pressing need for further research to improve clinical practice in this area of stroke care.

Abstract
Torsades de pointes (TdP), a form of ventricular arrhythmia that can cause ventricular fibrillation and sudden death, may occur during prolongation of the QT interval. QT prolongation has recently been reported with antipsychotic drugs. Physicians should be able to obtain a corrected measurement of the QT interval. QT is measured from the beginning of the QRS complex to the end of the T wave (QTm). This value must then be corrected to take heartbeat into account. The most common formula in current use is Bazett's. In practice, a QTc interval value greater than 500 ms indicates an increased risk of TdP. Safe combinations of antipsychotic drugs have been recommended by the French drug agency (Agence française de sécurité sanitaire des produits de santé). Many other drugs, including psychotropic drugs such as tricyclic antidepressants, can prolong the QT interval. Combinations of these medications with one another, with antipsychotic medications, or with other concomitant factors, such as hypokalemia, also increase the risk. TdP is most often diagnosed only after observing QT prolongation. This underlines the need to monitor QT intervals attentively to prevent the risk of cardiac arrhythmia in patients treated with antipsychotic drugs.
