Abstract
BACKGROUND AND STUDY AIM Schizophrenia (SZ) is a multifactorial disorder involving complex interactions between genetic and environmental factors, where immune dysfunction plays a key etiopathogenic role. In order to explore the control of innate immune responses in SZ, we aimed to investigate the potential association between twelve TLR2, TLR4 and TLR9 variants (TLR2: rs4696480T>A, rs3804099T>C, rs3804100T>C; TLR4: rs1927914G>A, rs10759932T>C, rs4986790A>G, rs4986791T>C, rs11536889G>C, rs11536891T>C; TLR9: rs187084A>G, rs352139T>C and rs352140C>T) and SZ susceptibility in a Tunisian population. PATIENTS AND METHODS This study included 150 patients and 201 healthy controls with no history of psychiatric illness. Genotyping was done using a TaqMan SNP genotyping assay. We also assessed a haplotype analysis for TLR2, TLR4 and TLR9 variants with SZ using Haploview 4.2 Software. RESULTS We found that the AA genotype of the TLR2 rs4696480T>A variant was significantly associated with an increased risk of SZ (46% vs. 31%, P=4.7×10-3, OR=1.87 and 95% CI [1.18-2.97]). The frequency of the TA genotype was significantly higher in the control group than in SZ patients (27% vs. 43%, P=2.1×10-3) and may be associated with protection against SZ (OR=0.49 and 95% CI [0.30-0.80]). Whereas, the TLR9 rs187084-GG genotype was higher in the control group compared to patients (16% vs. 5%, P=1.6×10-3) and would present protection against SZ (OR=0.28, CI=[0.10-0.68]). The ACT haplotype of the TLR2 and the ACC haplotype of the TLR9 gene were identified as a risk haplotypes for SZ (P=0.04, OR=9.30, 95% CI=[1.11-77.71]; P=3×10-4, OR=6.05, 95% CI=[2.29-15.98], respectively). CONCLUSION The results indicate that TLR2 and TLR9 genetic diversity may play a role in genetic vulnerability to SZ. However, including more patients and evaluation of TLR2 and TLR9 expression are recommended.

Abstract
OBJECTIVE Describe and compare the clinical profile of schizophrenic patients with and without obsessive-compulsive symptoms and obsessive-compulsive disorder (OCD) patients. METHODS A descriptive and analytical cross-sectional study was carried out at the psychiatry department of Hassan II University Hospital in Fez over 12 months to compare three groups of patients: "schizo-obsessive" (n=32), "schizophrenia" (n=34), and "OCD" (n=46). All participants (n=112) were assessed using the mini-international neuropsychiatric interview (MINI), the Yale-Brown obsessive-compulsive scale (Y-BOCS), the Brown assessment of beliefs scale (BABS), the Hamilton anxiety rating scale (HAM-A), the Beck's depression inventory (BDI-II), the positive and negative syndrome scale (PANSS), and the clinical global impressions-severity scale (CGI-S). RESULTS The "schizo-obsessive" group differed from the "schizophrenia" group in: more severe psychotic symptoms (mean=64.16±17.049, P<0.001), higher anxiety (mean=8.87±5,655, P<0.001) and depression (mean=7.50±5.989, P<0.001) scores, more prevalent suicide attempts (46.9%), higher illness severity score (mean=5.13±1.157, P=0.02), and more professional disinsertion (78.1%). The "schizo-obsessive" group (mean= 14.47±3.388) had significantly poor insight (P<0.001) compared to the "OCD" group (mean= 8.35±4.542). There were similarities in the obsessive and compulsive themes between the "schizo-obsessive" and the "OCD" groups, with no significant difference of severity (P=0.26). CONCLUSION A careful assessment of obsessive symptomatology is essential in schizophrenia for better patient management and prognosis.

Abstract
OBJECTIVES Schizophrenia is a complex and chronic neuropsychiatric disorder. Recent genome-wide association studies have identified several at risk genetic variants, including two single nucleotide polymorphisms, namely the rs10503253 and the rs1270942 respectively located in the CSMD1 and the CFB loci. The present case-control study was designed to assess potential associations between the two variants and the risk of developing schizophrenia and disease severity. Further we demonstrate the relationship between these variants and clinical characteristics in a population-group from Tunisia. PATIENTS AND METHODS In total, 216 patients diagnosed with schizophrenia along with176 healthy controls were included in this case-control study. The molecular analysis of the two polymorphisms was performed using tetra the Primer Amplification Refractory Mutation System-Polymerase Chain method. The statistical analysis was done using Compare V2.1 software, and correlations between genetic results and clinical characteristics were examined by Kruskal-Wallis testing. RESULTS The frequency of the rs10503253A allele was found significantly higher among patients with schizophrenia as compared to healthy controls and associated with high negative PANSS scores. While no association was found concerning the implication of the rs1270942 variant in schizophrenia risk, a positive correlation with high positive PANSS scores was further observed. CONCLUSION The present finding confirms the previously reported association between the Cub and Sushi multiple Domain 1 rs10503253A allele and the risk to develop schizophrenia and identified the rs1270942 variant as a potential disease risk modifier. Such observations may be important for the definition of the susceptible immunogenetic background in North African individuals at risk to develop mental disorders.

Abstract
Despite being one of the most common complaints of people with schizophrenia, fatigue remains largely unexplored in this population. The lack of knowledge regarding this complex symptom makes it often underdiagnosed and undertreated in schizophrenia. The aim of this brief perspective review is to outline the potential origins (distinguishing primary and secondary fatigue) and consequences of fatigue and to explore some potential treatments in this population. The current literature in schizophrenia has mainly investigated fatigue as a trait, using a self-administered questionnaire. Beyond this observational approach, which does not allow to capture the symptom in real life situations where high levels of fatigue can emerge rapidly, we propose to consider the state level of fatigue, for instance occurring after a prolonged period of cognitive activity (i.e. mental fatigue). We elaborate on the potential relationships between mental fatigue and negative symptoms of schizophrenia and propose some research avenues to test the effects of acute fatigue on effort intentions and behaviours. The consideration of the multidimensional aspects of fatigue will allow to move beyond the sole pharmacological approach to treat fatigue in schizophrenia. Targeting the cognitive as well as the performance components of fatigue through interventions such as concomitant aerobic exercise - mental training offers attractive prospects to reduce fatigue in this population and minimize its functional negative impact.

Abstract
Psychotropic drugs may be associated with metabolic disorders, often but not only triggered by weight gain. Disorders include dysglycemia and diabetes, atherogenic dyslipidemia and metabolic syndrome. Overall, metabolic risk is lower with antidepressants than with antipsychotics. Among antidepressants, metabolic disorders may occur with both selective serotonin reuptake inhibitors and tricyclics, but with some between-molecule differences in each pharmacological family. Among antipsychotics, the risk is higher with second-generation (atypical) than first-generation agents. Higher risk was reported with clozapine and olanzapine, and lower risk with risperidone and aripiprazole. Weight gain is associated with increased insulin resistance, but impaired insulin secretion was also reported with clozapine and olanzapine. Metabolic disorders may be attenuated by the medication withdrawal and replacement by another safer drug. Besides deleterious effects of medications, the psychiatric population is also exposed to bad lifestyle habits (unhealthy diet and sedentary life), which also increase the risk of metabolic disorder. Management should first reinforce lifestyle measures. If this proves insufficient, specific drugs may be considered to tackle the metabolic disorder on a strategy similar to that applied in the general population.

Abstract
BACKGROUND Promoting the cessation of smoking in mental healthcare is a priority of international health organizations as it is the most cost-effective intervention in psychiatry. AIM To explore the representations of psychiatrists on their role in active smoking cessation prevention in severe psychiatric disorders. METHODS Psychiatrists and residents in psychiatry were recruited at a national level by professional mailings. RESULTS One thousand four hundred and sixty participants were included in the study, and only 46% reported actively promoting smoking cessation. In multivariate analyses, participants aged<35years were more likely to promote cessation of tobacco smoking, as well as the two thirds who believe that psychiatry is a systemic discipline with complex interactions between brain, body and mind. Almost two thirds of those promoting tobacco cessation reported lacking time to combine psychiatric and physical examination during one session. The psychiatrists who reported not promoting tobacco smoking cessation also reported never dealing with physical health in case of the absence of a general practitioner and thinking that physical examination may have a negative impact on the therapeutic relationship. Almost all (96%) reported promoting the need for a general practitioner for their patients. We found no significant difference between the public and private sectors (P>0.05). INTERPRETATION Young psychiatrists are more prone than their elders to promote smoking cessation but report lacking time to include it in their daily practice. Promotion of tobacco smoking cessation should be included in the components for quality evaluation for mental health services and specific sessions dedicated to this intervention.

Abstract
INTRODUCTION Stigma underlies the violation of certain social, economic, and cultural rights of patients with schizophrenia, including their access to treatment and care. Measurement of stigma remains as complex and multifaceted as the phenomenon itself. Several measurement tools are available to assess the prevalence, intensity and qualities of stigma. The aim of the study was to carry out a cross-cultural adaptation of the Explanatory Model Interview Catalogue (EMIC), in the Moroccan Arabic dialect commonly known as "Darija". PATIENTS AND METHOD The study was conducted in three psychiatric departments of public hospitals in the Souss-Massa region, located in southern Morocco. For the diagnosis of schizophrenia, the study was based on the decisions of the psychiatrists practicing at the study sites. The cross-cultural adaptation in Moroccan Darija of the stigma scale developed by Michel Weiss in the EMIC was carried out according to the six-step scientific method developed by Dorcas et al. RESULTS Cronbach's alpha (internal consistency) was 0.845. Convergent validity determined by Pearson's coefficient showed a significant inter-item correlation and the intra-class correlation coefficient (test-retest) was 0.975 (0.993; 0.991). The item added in relation to the COVID-19 situation presented psychometric values similar to the others. CONCLUSION The Darija version is culturally acceptable and can be used to approach the phenomenon of stigmatization in Morocco.

Abstract
OBJECTIVES Research indicates that many patients with schizophrenia experience deficits in metacognitive capacity defined as the ability to form complex representations of themselves and others. The aim of the current study was to assess metacognitive deficit in patients with schizophrenia. These variables were collected together with many other sociodemographic, clinical and therapeutic data. METHODS We conducted a descriptive and analytical cross-sectional study in the psychiatry department at the Hedi Chaker University Hospital in Sfax (Tunisia). Patients were in a non-acute phase, defined by the absence of any psychiatric symptoms during the last four weeks, also, no changes in medication during the previous month had been required. An informed written consent was obtained, following which patients completed questionnaires assessing sociodemographic and clinical data during structured interviews. Symptoms and severity of the illness were assessed using the Positive and Negative Symptoms Scale (PANSS). Insight was assessed using the Insight Scale (Q8). In addition, the Metacognition Assessment Scale-Abbreviated (MAS-A) was used to assess metacognitive capacities. The MAS-A contains four dimensions: self-reflectivity, awareness of the mind of others, decentration, and mastery. Higher scores reflect an ability to effectively respond to psychological challenges on the basis of psychological knowledge. RESULTS We recruited 74 adults with schizophrenia disorder. The diagnosis was with DSM5. Their average age was 45 years (SD=9.84 years) with a sex ratio (M/F) of 1.552. Nineteen patients (25.5%) were married, and low educational level was present in 43% of cases. Forty patients (54%) were unemployed. Metacognitive deficit was detected in all the patients. They had low levels in all four dimensions of metacognition. The most affected dimension in our series was "Mastery". All patients had an overall insight score less than six (the average score was 2.73) with poor awareness in 62% of patients. The main factors correlated with metacognitive deficit were: occupational inactivity (P-0.015), Primary education level (P=0.045), tobacco consumption (P=0.002), low insight (P-0.001), negative symptomatology (P<10-3) and the use of first generation of antipsychotics (P=0.003). The multivariate analysis showed that three factors (occupational inactivity, low insight and the presence of negative symptomatology) were predictors of metacognitive deficits. CONCLUSION Based on our results, occupational inactivity, negative symptomatology and low insight are predictors of metacognitive deficit in schizophrenia. Specific therapeutics should be proposed to act on these factors. A metacognitive training program, tailored to this vulnerable population, is a priority to improve their quality of life.

Abstract
Mental illness affects 48.9 % of the Moroccan population. Despite this significant figure, mental illness remains unrecognized. The patients suffering from mental disorders are therefore subject to stigma and social rejection. A descriptive study was conducted at the consultation service of the psychiatric Ibn Nafiss hospital of the CHU of Marrakech. We chose as a sample 100 stabilized patients, followed on an outpatient basis. The study included the three mental disorders: depressive disorder, bipolar disorder, and schizophrenia. The number of patients in each group had been fixed beforehand; and we tried to get a fairly even distribution between the two genders. The questionnaire had three main axes: (1) Sociodemographic data of the patient. (2) Knowledge of the disease. (3) Evaluation of the experience of stigma. The results of our sample were as follows: For both sexes the age extremes were 19 to 68 years with an average of 38.5 with a clear predominance of women. For the entire population, most patients were single with a percentage of 60 %. Two thirds of the patients, i.e. 59 %, did not exceed primary school. For personal medical history, endocrine pathologies were the most prevalent, at 18 % of cases, while depression was the most common family psychiatric history in our study. We noticed that our population suffered more discrimination and disclosure from those around them regardless of family, social and professional with less appreciation of the positive aspects.

Abstract
OBJECTIVES We assessed the prevalence of severe cardiovascular (CV) disease requiring hospitalization among patients with schizophrenia in France. METHOD We included patients hospitalized with schizophrenia or psychotic disorder during 2015, in five French psychiatric hospitals. Patients with CV disease were defined as those with a correspondent ICD-10 code during a hospital stay in any general hospital, five years before or three years after the psychiatric hospitalization. CV disease included myocardial infarction (MI), stroke, heart failure (HF), coronary artery disease (CAD) or peripheral artery disease. Risk factors such as hypertension, obesity and diabetes were recorded. RESULTS In total, 4424 patients with schizophrenia were included. Overall, 203 (4,6%) patients were diagnosed with CV disease, 93 (2.1%) with CAD, 86 (1.9%) with HF and 49 (1.1%) with stroke. The prevalence of hypertension, obesity and diabetes was 11.3%, 9.7% and 7.8%. The median (interquartile range) age of patients with MI and diabetes was 57 (49-70) and 56 (48-66) years. CONCLUSION Patients with schizophrenia develop severe CV disease requiring hospitalization at an early age. These severe events are associated with a high prevalence of risk factors. Early screening and treatment of CV disease and risk factors is important to improve life expectancy and quality of life of these patients.

Abstract
OBJECTIVES Attention Deficit with/without Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with frequent comorbid psychiatric disorders. Several studies have underlined the increased risk of developing a psychotic disorder subsequent to a childhood ADHD. The aim of our review is not only to clarify this association and the related physiopathology but also to understand the consequences for therapeutic management. METHODS We processed a narrative review of available literature based on a research of the PubMed database. Articles related to ADHD and psychotic disorder on a genetical, clinical or biological level were selected by one of the authors. RESULTS ADHD and psychotic disorders share neonatal, environmental, and genetic risk factors. On a neurobiological level, both disorders are concerned by a dysfunction of the dopaminergic system with an abnormal regulation of dopaminergic neurons' phasic and tonic activity. Our review aims to explain the « dynamic » model of dopaminergic dysfunctions and propose some guidance for pharmacological treatment of ADHD, with or without psychotic disorder. This model offers a better understanding of why methylphenidate is not associated to an increased risk of psychotic disorder and could act as a protective factor. Association between ADHD and psychotic disorders could be explained by some comorbidities such as substance use disorders which are frequently associated with both conditions and could act as mediator in the genesis of psychotic disorders following ADHD during childhood. Our review also focuses on an epidemiological bias that could be found in some studies such as possible diagnostic errors, as some non-specific clinical signs could be found in both late diagnosed ADHD and in "at risk mental state" of psychosis. CONCLUSION ADHD and psychotic disorders share common risk factors, neurobiological pathways and clinical symptoms. Perspectives for future studies are proposed considering a dimensional aspect of psychiatric disorders using, for example, Research Domain Criteria and exploring the link between the two conditions.

Abstract
OBJECTIVES This systematic literature review focused on patients suffering from schizophrenia (SZ), psychotic disorders or mental illness (MI) including SZ. It was interested in data on prevalence of electronic cigarette (EC) use, patient perceptions and expectations, as well as caregivers' attitudes towards the EC and its benefit in helping to stop or reduce smoking. METHOD The research was carried out on Medline for the period 2000-2020. Cross-sectional, case-control, prospective, randomized controlled studies and preliminary studies were included in this review. RESULTS EC is widely used by MI patients with current and lifetime use from 7.4% to 28.6%. More specifically, patients with SZ and schizoaffective disorders observe current and lifetime use from 7% to 36%, respectively. Many reasons are given by patients for its use including the possibility of using it in places where smoking is prohibited, its lower toxicity compared to cigarettes for oneself and those around, its lower cost, and the help provided to reduce consumption. CONCLUSION EC is used by smokers with MI; several studies confirm the possibility for these smokers to reduce tobacco consumption through EC and without disturbing their mental state. However, its value in helping to quit smoking remains uncertain.

Abstract
Schizophrenia is associated with a weighted average of 14.5 years of potential life lost according to a recent meta-analysis. This is partly explained by high rates of suicide and a high prevalence of non-psychiatric comorbidity (cardiovascular diseases, diabetes, cancers…). However, all these causes could not fully explain the loss of life expectancy in people suffering from schizophrenia. Life expectancy has been strongly correlated with telomere length (TL). Telomeres are noncoding structures consisting of DNA TTAGGG tandem repeats and associated proteins located at the end of the chromosomes. Their role is to help preserve genome stability by protecting chromosomal ends from the loss of genetic material. The progressive loss of telomeric material during cell divisions has led researchers to consider telomeres as molecular clocks that measure the number of divisions left until cellular death. The fact that both shorter telomeres and schizophrenia have been associated with a decrease in life expectancy has fueled the interest in the study of TL in schizophrenia. In this article, after a detailed review of the literature on the relationships between telomere length and schizophrenia, we discuss the different pathophysiological mechanisms which might explain this association. Based on this analysis, in the last part of the article we discuss potential research, therapeutic and prevention prospects. To date, the majority of the studies and meta-analyses found a decrease in TL in subjects with schizophrenia compared to control subjects. Conversely, all the studies exploring the TL in subjects suffering from first episode psychosis (FEP) have shown no significant difference from TL in control subjects. This suggests that excessive shortening of telomeres occurs during the course of the disease, thus it seems more probable that schizophrenia (or processes associated with it) affects TL rather than telomere erosion being a cause of the disorder. Several pathophysiological, non-mutually exclusive mechanisms have been proposed to explain the observed data. A first hypothesis to explain the acceleration of the physiological process of telomere erosion in schizophrenia is the activation of inflammation processes and oxidative stress as a consequence of schizophrenia per se. However, it seems more probable that reduced TL may be a result of cumulative exposure to chronic stress related to schizophrenia. Indeed, in healthy individuals a growing body of evidence has linked chronic stress to accelerated shortening of TL. This might explain why telomere erosion is too small to be detected in FEP patients who are younger and have a shorter duration of illness than subjects with schizophrenia. Based on these both explanations, telomere alterations may be considered as a biomarker of illness progression and might be useful for illness staging. Identifying processes associated with TL reduction might improve our understanding of the increased mortality and morbidity in schizophrenia, improve reliability of diagnosis, and hopefully suggest means for prevention and/or treatment. Treatments that prevent exposure and/or vulnerability to stressful life events that ameliorate schizophrenia may also prevent or decelerate telomere erosion. In this perspective, engaging subjects suffering from schizophrenia in a healthy diet and regular activity could be both promising strategies to protect telomere maintenance and improve health span at old age. In addition, the inflammatory process and oxidative stress involved in the physiopathology in at least a subgroup of subjects with schizophrenia could also be responsible for telomere erosion. Thus, an efficient anti-inflammatory therapeutic approach that targets these specific pathways could be of interest in this subgroup to limit telomere erosion. Mindfulness-based stress reduction (MBSR) therapies have been shown to reduce telomere erosion by increasing telomerase activity, although these psychological therapies should be used carefully in psychosis. Finally, advancing our understanding of the relationship between stress, inflammation and TL is of great interest for psychiatric research and for understanding stress effects in this population.

Abstract
OBJECTIVES The present study focuses on a review of scientific literature upon structural and functional abnormalities of the insular cortex found in schizophrenic patients in order to emphasize links between the pathophysiology of this brain region and the symptomatology of schizophrenia. METHODS From a review based upon journal articles published since 2002 and indexed into the Pubmed data base, we first studied the main findings on the function of the insular cortex and its involvement in the perception and representation of the body states, as it is one of the main neural substrates for the interoception sense. Then, we highlighted various structural abnormalities found in schizophrenic patients in order to study links existing between dysfunctions in the insular cortex and an altered perception of body states and of self-awareness in schizophrenia. Eventually, we studied the links emphasized between functional abnormalities of insula in schizophrenia and a positive symptomatology, especially auditory hallucinations. RESULTS The data in the neurobiological literature about abnormalities in the insular cortex in schizophrenia has demonstrated that insula dysfunctions could constitute one of the biological substrates of disorders of body perception in schizophrenia, and it could be a source of the alteration of the sense of self that is characteristic of this psychiatric pathology. Moreover, the importance of insula in processing interoceptive stimuli and their integration with exteroceptive stimuli could engender a problem in the discrimination between endogenic and exogenic stimuli, a problem that could thus be involved in the positive symptomatology of schizophrenia, such as auditory hallucinations and delusion. CONCLUSIONS Scientific knowledge in the role of the insula for the perception and representation of the body states shows that the insula has a key role for interoception. Functional abnormalities of the insular cortex in schizophrenia may lead to the conclusion that this area of the brain is one of the biological substrates for the disorders of body perception in schizophrenia, and also, mainly, one of the substrates for the disorders of self-awareness which depends, according to many authors, on the representation of the body states. Moreover, the role of the insula in integrating interoceptive and exteroceptive stimuli leads to the supposition that dysfunctions of the insula could result in a problem concerning the discrimination between endogenic and exogenic stimuli, and thus could create a positive symptomatology, mainly auditory hallucinations for schizophrenic patients. It needs to be noted that the links between the symptomatology of schizophrenia and the dysfunctions of the insular cortex are still in debate among researchers. Recent researches do not allow to conclude with accuracy of a systematic correlation between psychopathology of schizophrenia and functional abnormalities of the insula, although it seems obvious to find a link between these psychopathological and neurobiological phenomena.

Abstract
OBJECTIVES Schizophrenia spectrum disorders are associated with incapacitating social impairments, mostly due to Theory of Mind (ToM) deficits. Theory of mind difficulties often precede the beginning of schizophrenia spectrum disorders and contribute highly to the social withdrawal of patients. They also predict bad outcome for individuals suffering from this condition. The use of samples of individuals presenting subclinical forms of schizophrenia spectrum disorders constitute an opportunity to study theory of mind capacities. Notably, the study of theory of mind deficits in schizotypy allows a better understanding of predictive markers of schizophrenia spectrum disorders. They also contribute to the identification of primary processes involved in social difficulties associated with these disorders. METHODS We searched PubMed, Science Direct and Google Scholar databases for peer-reviewed articles studying the association between theory of mind performance and schizotypal traits up to the 1 April 2020. The following syntax was used: schizotypy AND ("theory of mind" OR "social cognition" OR "irony" OR "false belief" OR "social inference" OR "hinting task"). We also checked the references from these articles for additional papers. Only English and French written articles were considered. RESULTS Twenty-three articles were included in the review. The majority of these studies (n=20) used behavioral measures of theory of mind (i.e. percentages of correct responses on a theory of mind task). Only a few (n=3) recent studies used brain imaging to study theory of mind in psychometric schizotypy. In those 23 studies, 18 report theory of mind difficulties in individuals with high schizotypal traits. Ten out of these 19 studies report an association between positive schizotypy and theory of mind deficits/hypomentalizing. The positive dimension was the most associated with theory of mind difficulties. The negative dimension was associated with theory of mind deficits in six studies out of 19 (33 %). The association between disorganization and theory of mind deficits was weak, mostly because of a lack of studies measuring this dimension (only one study out of 13 measured this particular trait). The association between hypermentalizing and schizotypy was poorly characterized, due to high heterogeneity in how this feature was conceptualized and measured. In summary, some authors consider good performance on a theory of mind task as a sign of hypermentalizing, while other authors consider that this feature relates to the production of erroneous interpretations of mental states. We advocate in favor of the second definition, and more studies using this framework should be conducted. Interestingly, the three studies using fMRI showed no significant behavioral differences between high and low schizotypal groups on theory of mind performance, while the patterns of brain activation differed. This shows that in individuals with schizotypy, theory of mind anomalies are not always captured just by behavioral performance. Brain imagery should be included in more studies to better understand theory of mind in schizotypy. In general, high heterogeneity in ways of assessing schizotypy, and in the tasks used to evaluate theory of mind, were found. Notably, some tasks require shallower theory of mind processing than others. It is a priority to design theory of mind tasks that allow for manipulating the difficulty of the items within one task, as well as the level of help that can be given, in order to allow for a better assessment of the impact of theory of mind difficulties and the ways to compensate for them. CONCLUSIONS The studies included in this review confirm the association between psychometric schizotypy and theory of mind. But the high heterogeneity in methods used in these studies, and notably the diversity in ways of assessing schizotypal traits and theory of mind, hinder a precise description of such an association. Additional studies are required. In particular, fMRI studies using tasks allowing for a precise description of altered and preserved theory of mind processes could be of great use in characterizing theory of mind difficulties associated with schizotypy.

Abstract
OBJECTIVES The aim of this study was to adapt and validate the Schizophrenia Caregiver's Quality of Life Questionnaire (S-CGQoL) for use in the Hispanic-American population from the caregiver's perspective. METHODS A cross-sectional instrumental model was used, with a sample of 253 caregivers of patients suffering of Schizophrenia in Bolivia, Peru and Chile. The psychometric properties of the S-CGQoL were tested through construct validity, reliability and some aspects of external validity. In addition, in order to assess the nature of the different items across the three countries, a Differential Performance Analysis (DPA) was conducted. RESULTS A confirmatory factor analysis showed that the scale structure was well correlated to the initial structure of the QoL-MDS. The results confirmed the existence of adequate reliability indicators (α>.70 and ω>.80) and the absence of FIDs supporting the invariance of item calibrations among the three Latin American countries. CONCLUSIONS The adaptation and validation of the S-CGQoL questionnaire demonstrate adequate psychometric properties to assess the quality of life of caregivers in samples of middle-income countries in Latin America.

Abstract
INTRODUCTION Altered glutathione systems (GSH) are suggested to participate in the pathophysiology of schizophrenia. The purpose of this study was to determine the plasmatic glutathione levels of patients with schizophrenia compared to healthy controls and to examine their relationships with clinical and therapeutic features. METHODS It was a case-control study carried out on 100 patients with schizophrenia according to DSM-IV-TR criteria and 95 healthy controls. All patients were assessed by Clinical Global Impressions-severity (CGI-severity) and Global Assessment of Functioning (EGF). Most of the patients (55%) were under first-generation antipsychotics. Plasmatic glutathione levels (total glutathione GSHt, reduced glutathione GSHr, oxidized glutathione GSSG) were determined by spectrophotometry. RESULTS The levels of GSHt and GSHr were significantly decreased in schizophrenic patients in comparison with the healthy controls. These reductions were noted to be more pronounced in the untreated patients. No correlation was observed between the GSH levels and the clinical subtypes of schizophrenia and EGF scores. Depending on the therapeutic status, there were no significant differences in the GSH levels. In addition, there was no correlation between the GSH levels and the daily dosage of the antipsychotic treatment. CONCLUSION Our results suggest that the observed changes are related to the physiopathology of schizophrenia rather than to the presence of neuroleptic treatment. These results provide support for further studies of the possible role of antioxidants as neuroprotective therapeutic strategies.

There is growing evidence for a main role of environment in the occurrence of mental disorders such as a psychosocial risk factor, for example, childhood trauma, discrimination linked to minority status, or migrant status. One hypothesis is that social adversity factors influence the risk of schizophrenia through a common pathway: social defeat which could be defined as the impotence of a subject in the face of a situation of social adversity, with a consequential experience of devaluation on the social scale. This review proposes to explain the animal model of social defeat which provides an overview of the neurobiological consequences of chronic stress. Then, we expose this topic in humans, the assessment methods, and its psychopathological field. Finally, we expose epidemiologic and neurobiological evidences, in particular the dopaminergic sensitization process, which provide evidence of a significant role of social defeat in schizophrenia risk due to exposure to psychosocial factors. This etiopathogenic hypothesis has several issues. First, a common pathway to several environmental risk factors could allow an ethiopathogenic model more parcimonious for schizophrenia. It could also allow the assessment and prevention of adversity factors involved in social defeat so as to finally improve the outcome of subjects who have an individual risk for schizophrenia.

Abstract
Background There is limited information describing the presenting characteristics and outcomes of patients with schizophrenia (SCZ) requiring hospitalization for coronavirus disease 2019 (COVID-19). Aims We aimed to compare the clinical characteristics and outcomes of COVID-19 SCZ patients with those of non-SCZ patients. Method This was a case-control study of COVID-19 patients admitted to 4 AP–HM/AMU acute care hospitals in Marseille, southern France. COVID-19 infection was confirmed by a positive result on polymerase chain reaction testing of a nasopharyngeal sample and/or on chest computed scan among patients requiring hospital admission. The primary outcome was in-hospital mortality. The secondary outcome was intensive care unit (ICU) admission. Results A total of 1092 patients were included. The overall in-hospital mortality rate was 9.0%. The SCZ patients had an increased mortality compared to the non-SCZ patients (26.7% vs. 8.7%, P = 0.039), which was confirmed by the multivariable analysis after adjustment for age, sex, smoking status, obesity and comorbidity (adjusted odds ratio 4.36 [95% CI: 1.09–17.44]; P = 0.038). In contrast, the SCZ patients were not more frequently admitted to the ICU than the non-SCZ patients. Importantly, the SCZ patients were mostly institutionalized (63.6%, 100% of those who died), and they were more likely to have cancers and respiratory comorbidities. Conclusions This study suggests that SCZ is not overrepresented among COVID-19 hospitalized patients, but SCZ is associated with excess COVID-19 mortality, confirming the existence of health disparities described in other somatic diseases.

Abstract
OBJECTIVE The SARS-CoV-2 (or COVID-19) pandemic has been propagating since December 2019, inducing a drastic increase in the prevalence of anxious and depressive disorders in the general population. Psychological trauma can partly explain these disorders. However, since psychiatric disorders also have an immuno-inflammatory component, the direct effects of the virus on the host's immune system, with a marked inflammatory response, but also the secondary inflammation to these psychosocial stressors, may cause the apparition or the worsening of psychiatric disorders. We describe here the probable immunopsychiatric consequences of the SARS-CoV-2 pandemic, to delineate possible screening actions and care that could be planned. METHOD Data from previous pandemics, and existing data on the psychopathological consequences of the SARS-CoV-2 pandemic, allowed us to review the possible immunopsychiatric consequences of the SARS-CoV-2 pandemic, on the gestational environment, with the risk of consecutive neurodevelopmental disorders for the fetus on one hand, on the children and adults directly infected being at increased risks of psychiatric disorders on the other hand. RESULTS As in previous pandemics, the activation of the immune system due to psychological stress and/or to infection during pregnancy, might lead to an increased risk of neurodevelopmental disorders for the fetus (schizophrenia and autism spectrum disorders). Furthermore, in individuals exposed to psychological trauma and/or infected by the virus, the risk of psychiatric disorders, especially mood disorders, is probably increased. CONCLUSION In this context, preventive measures and specialized care are necessary. Thus, it is important to propose a close follow-up to the individuals who have been infected by the virus, in order to set up the earliest care possible. Likewise, in pregnant women, screening of mood disorders during the pregnancy or the postpartum period must be facilitated. The follow-up of the babies born during the pandemic must be strengthened to screen and care for possible neurodevelopmental disorders.

Abstract
Interictal psychosis (IIP) refers to psychosis that occurs in clear consciousness in persons with epilepsy (PWE) with temporal onset not during or immediately following a seizure. The pooled prevalence estimate of psychosis in PWE is 5.6%. PWE and schizophrenia have very high mortality, and more than one in four persons with both disorders die between the age of 25 and 50years. IIP can manifest in brief or chronic forms. The chronic forms of IIP may closely resemble schizophrenia. However, some authors have described the typical presence of persecutory and religious delusions, sudden mood swings and the preservation of affect, as well as rarity of negative symptoms and catatonic states, but these differences remain controversial. Typically, IIP starts after many years of active temporal lobe epilepsy. Several epilepsy-related variables are considered pathogenically relevant in IIP including epilepsy type and seizure characteristics. Risk factors for developing IIP are family history of psychosis, learning disability, early age of onset of epilepsy, unilateral or bilateral hippocampal sclerosis, history of status epilepticus, history of febrile seizures, and poorly controlled temporal lobe epilepsy. In patients with epilepsy and psychosis, structural imaging studies have shown several relevant changes leading to conflicting findings. Altered neuronal plasticity and excitability have been described in epilepsy and psychotic disorders. Neuropathological data suggest that IIP are not the result of classic epileptic pathology of the temporal lobe. Forced normalization (FN) and alternating psychosis refer to patients with poorly controlled epilepsy (focal or generalized) who have had psychotic episodes associated with remission of their seizures and disappearance of epileptiform activity on their EEGs. FN mainly occurs in temporal lobe epilepsy when patients have frequent seizures that are abruptly terminated triggered by an antiepileptic drug, vagus nerve stimulation or epilepsy surgery. Treatment is based on withdrawal of the responsible drug, and by transient use of antipsychotics for acute symptomatic control on a case-by-case basis. FN is an entity whose pathophysiology remains uncertain. Antiepileptic drugs (AEDs) may sometimes induce psychotic symptoms and psychosis could be a direct effect of the AEDs. IIP has been reported more frequently following the initiation of zonisamide, topiramate, and levetiracetam when compared with other antiepileptic drugs. However, AEDs do not appear to be the only determinant of IIP. The management of IIP requires a multidisciplinary approach with early involvement of a liaison psychiatrist associated with a neurologist. IIP are underdiagnosed and mistreated. Existing recommendations are extrapolated from those established for the treatment of schizophrenia with some additional guidance from expert opinions. A two-step procedure, not necessarily consecutive, is suggested. The first step requires reevaluation of the antiepileptic treatment. The second step requires initiation of atypical neuroleptics. Antipsychotic drugs should be selected with consideration of the balance between pharmacological profiles, efficacy, and adverse effects. Regarding pharmacokinetic interactions, AEDs with inducing properties reduce the blood levels of all antipsychotics. It is important to consider implications of combining neuroleptics and AEDs with a similar spectrum of side effects. Regarding the duration of treatment, IIP episodes are more likely to be recurrent than in primary schizophrenia. In practice, atypical neuroleptics with few motor side effects such as risperidone can be used as first choice, given the low propensity for drug-drug interactions and the low seizure risk, with the added suggestion to start low and go slow. Clozapine could be prescribed in selected cases.

Abstract
OBJECTIVES Although mortality by suicide in schizophrenia seems to have decreased in some countries over the last 30 years, it remains much higher than in the general population. Studies have shown this risk to impact around 5% of patients, corresponding to a risk almost 2.5 times higher than in the general population. Family psychoeducation in schizophrenia has been demonstrated to lead to symptom reductions and to an improvement of the quality of life, two factors that should contribute to decreasing the suicidal risk. Therefore, if families attend an efficient psychoeducation program, we can expect a decrease in the patient suicidal risk. Attending a family psychoeducation program at the beginning of the disease would also be associated with a stronger preventive effect on suicidal mortality. The objective of this study is to describe the suicide attempt rate of patients who suffer from schizophrenia before and one year after one of their relatives participated to the family psychoeducation program Profamille. METHOD We performed a retrospective study on 1209 people who attended the Profamille (V3.2 version) Family Psychoeducation Program. This program has 2 modules: an initial training module of 14 weekly or fortnightly sessions, and a consolidation module of 4 sessions over 2 years. Sessions last 4 hours and follow a precise and structured course. Data were collected from 40 different centers in France, Belgium and Switzerland and were based on participants assessed at the beginning and one year after the first module. Self-assessment from the relatives participating in the program provided the measure of patients' suicide attempts. An assessment at T0 explored the attempts over the 12 months before the beginning of the program while the assessment at T1 analyzed those during the 12 months following the end of the Program. The Chi2 test was used to compare the suicide attempt rates for each period, using a significance threshold of 0.05. Since the risk of suicide is greater in the first years of the illness, rates of attempts are also calculated according to the age of disorder. The analysis was carried out with the statistical software R. RESULTS The number of participants reporting that their relative had attempted suicide in the previous 12 months decreased from 41 to 21. The annual attempts rate was evaluated at 6.4 % before the Profamille program and decreased to 2.4 % a year after the end of the program (P=0.0003). The reduction of the attempt rate was observed even for patients with schizophrenia for more than 10 years. CONCLUSION This study shows the positive impact of Profamille on reducing the rate of suicide attempts in patients with schizophrenia. It has been shown that the risk is highest at the beginning of the disorder. Therefore, based on our results, it would seem appropriate to propose the Profamille program at an early stage.

Abstract
AIMS Our article consists in both analysis and synthesis of contemporary cognitive models of auditory verbal hallucinations (AVHs) in schizophrenia. Our work is based on the analysis of the scientific literature including original articles, literature reviews as well as meta-analysis. METHODOLOGY In order to identify the most pertinent studies in the electronic search, the three following databases were systematically searched: PubMed, PsycINFO and MEDLINE. For both the analysis and synthesis we selected original articles, literature reviews as well as meta-analysis referring to any cognitive explanation of the auditory hallucinatory experience in schizophrenia. A cognitive model of auditory hallucinations refers to any incorporation of cognitive frameworks and explanations in one's conceptualization of the hallucinatory phenomenon in schizophrenia. We also focused our work on past conceptualization of auditory hallucinations in order to explain the development and the contribution of current cognitive models in the understanding of the onset and the maintaining of AVHs. After a brief review of clinical characteristics and historical conceptualization of auditory verbal hallucinations, contemporary explanations were presented in the area of schizophrenia. These explanations referred to researches into cognitive psychopathology including metacognitive as well as neuroimaging studies. RESULTS The examination of scientific literature highlighted the complexity of AVHs through multifactorial explanations here mostly explained by cognitive and metacognitive deficits. We synthesized former conceptualizations of AVHs, which were sustained on mechanistic or sensory explanations. Esquirol, Baillarger and Briere de Boismont were the first as conceiving AVHs as a perception disorder and introduced the idea that auditory hallucinations resulted from a failure to control one's memories/fantasies. Later, Broca and Wernicke discovered auditory areas in the human brain implicated in language comprehension and production. AVHs began to be conceptualized by the scientific world as being mechanistically brain-related. Sigmund Freud was among the first to study the meaning of AVHs, a domain still being investigated by todays cognitive sciences. More recently, neuroimaging studies allowed the validation of these sensory explanations in considering the onset of AVHs through the deficit of cortical and subcortical areas implicated in the process of languages (e.g. Broca and Wernicke areas) and emotions (e.g. limbic system, amygdala, hippocampus). At a more mechanistic level, contemporary cognitive models of AVHs explained AVHs as an intrusive verbal representation into the awareness which is non-inhibited (i.e. deficit in intentional inhibition) and also non-recognized as one's own experience (i.e. deficit in source monitoring, planning and metacognition), or even attributed to an external source (attribution bias). In terms of inhibitory control, inhibition is a basic cognitive mechanism defined as a collection of processes that allows the suppression of previously activated cognitive contents and the clearing of irrelevant actions or attention from consciousness. Intentional inhibition is effortful and occurs when an individual deliberately suppresses the activation of an item after deciding it is irrelevant. Theoretical support for the suggestion that an inhibitory failure is involved in AVHs in schizophrenia arises from studies that have shown that a failure in inhibition results in intrusive thoughts from long-term memory. Recent findings also found that individuals with AVHs in schizophrenia demonstrated an impaired source monitoring. In episodic memory research, a distinction was made between content (an event) and context (e.g. source or temporal characteristics of an event) information. The context of memories provides cues that allow an individual to differentiate one memory from other memories. AVHs are conceptualized as a failure to access the contextual cues that would allow voice-hearer to form an intact representation of events in memories. Regarding planning, AVHs refer to the intrusion of unwanted memories into the inner speech that are not recognized from one's own representation. Previous cognitive theories highlighted the important role played by metacognitive skills and belief (i.e. thinking about one's thinking) in the explanation of AVHs. Finally, the external attribution bias was extensively studied over the last three decades and refers to the tendency to attribute negative events (situational or cognitive) to an external source. In this framework, AVHs refer to intrusive thoughts externally attributed to a voice. CONCLUSION For more than one century, scientific discoveries in (bio)medical science have allowed the validation of former sensory and mechanistic explanations of AVHs. Nevertheless, many explanatory models account for the way AVHs are maintained (source monitoring, deficit in planning, externalizing bias), while they scarcely expose how they are triggered (intrusive thoughts, deficit in inhibition). The relation between AVHs and intrusive thoughts still remain unclear, and further studies are needed for the understanding of a potential causal relationship.

Abstract
OBJECTIVES Schizophrenia is a long-term, stigmatized disease which often leads to social impairment, unemployment and isolation, with heavy negative social and psychological consequences both on patients and their families. Close relatives' perceptions of the illness have an impact on their mood, and then on the course of the patient's disease itself. In this context, our objective is to evaluate the perceptions of French close relatives of people with schizophrenia or schizophrenia spectrum disorders, about the disease itself, as well as their experience within the mental healthcare system. METHODS Our population is constituted of close relatives of people experiencing schizophrenia or schizophrenia spectrum disorders, recruited through an active patient and families association. We used a French translation of a standardized questionnaire, the Brief Illness Perception Questionnaire, as well as an extensive semi-structured interview assessing the experience of the mental healthcare system (diagnosis divulgation, information about disease and treatment, family psychoeducation, hospitalization experience, and access to health professionals). Some questions in the last were open-ended questions, which allowed us to gather detailed and personal responses, in order to be able to illustrate our quantitative findings with brief clinical cases. RESULTS Among the 27 close relatives included in our research, results to the standardized questionnaires show threatening perceptions of the disease, in particular regarding the probable duration of the disease and the frequency of symptoms. In our study, a better access to diagnosis is associated with a shorter perceived probable duration of the disease, while an easier communication with healthcare professionals (in particular nurses) is associated with the perception of a better efficiency of the treatment. Family psychoeducation seems to be associated with the perception of less frequent symptoms. When the patient lives independently or is older, close relatives of our sample perceive a higher risk of chronicity of the disease. Our results tend to confirm the available literature on the subject of information towards families in psychiatric services: indeed, studies, especially in the field of nursing research, have shown that families tend to feel excluded from care processes and from useful information exchanges about the patient's illness. Our study also confirms the fact that family psychoeducation seems to reduce the frequency of present symptoms in the patient as perceived by the close relative. This effect could be caused by a better understanding of the real symptoms or by an enhancement of the family mood and functioning. Even if the patient's hospitalization was a difficult or very difficult experience for close relatives, it showed no relationship with their illness negative perceptions. Sociodemographic variables of the patient, such as age or the fact of living in an independent household, were associated in our research with the close relatives' view of a higher potential chronicity of the illness; this could be explained by a different stage of acceptation of the illness when compared to close relatives taking care of a younger or still dependent patient. CONCLUSIONS Our results plead for further research on a larger and less homogeneous sample. Confirming our findings could help build useful recommendations leading to better integrated families who currently seem to feel relatively isolated and exclused in the healthcare process, despite the strategic role they could play and despite the many recommendations of public health policies in that matter. Efforts should continue to be made to reach the goal of a better inclusion of families and close relatives of people experiencing schizophrenia or schizophrenia spectrum disorders, in particular in the field of information and communication with health professionals, both areas which seem to have a potential effect on close relatives' illness negative perceptions. Family psychoeducation deserves more attention and should be more systematically proposed to French families with an easier and free access.

Abstract
The pathogenic mechanisms underlying Schizophrenia (SZ), one of the most frequent mental disorders, are complex and poorly understood. Several evidences suggest that inflammatory processes may underpin some of its neurobiological correlates. The aim of this study was: (i) to analyze the potential association between circulating levels of the C-reactive protein (CRP), a crucial inflammatory marker, and Schizophrenia in Tunisian patients and healthy controls (HC) cohorts; (ii) to investigate the genetic diversity of three CRP variants (rs1417938, rs1130864 and rs1205) and; (iii) to analyze a potential relationship between expression and genetic data and clinical and socio demographical characteristics. CRP polymorphisms were exanimated for 155 patients and 203 HC by taqMan5'-nuclease. High-sensitivity CRP (hs-CRP) serum level was measured in 128 clinically stable out-patient SZ patients and 63 HC subjects via an automated biochemical analyzer. We found that hs-CRP levels were significantly higher in SZ patients as compared to HC. No significant differences were found when the proportions of CRP variants were compared in patients and HC. Further analysis according to clinical and socio demographical characteristics revealed a positive association with age and hypertension. Our data on an original Tunisian sample confirm the previous finding in others population groups.

Abstract
CONTEXT Patients suffering from schizophrenia present with a risk of cardiovascular death which is two to three times as high as the general population. OBJECTIVES Our study aims to evaluate the global cardiovascular risk according to SCORE and Framingham on patients suffering from schizophrenia who have been hospitalized in psychiatric institutions and also to assess whether being under the care of a physician affects that risk. METHODS A prospective descriptive epidemiologic study was conducted from April 2005 to March 2016. The study population consisted of adult patients suffering from schizophrenia who were hospitalized in the psychiatric unit of the CHU de Saint-Étienne. The data was collected during the clinical admission examination. The software CARDIORISK was used to compute the global cardiovascular risk according to SCORE and Framingham. RESULTS The average cardiovascular risk was about four times as high for males as it was for females according to the SCORE model and twice as high according to the Framingham model. According to the SCORE model, 16.5 % of the patients presented a high cardiovascular risk versus 6.6 % according to the Framingham model. There was no statistically significant difference between patients who were under the care of a physician and those who were not, both in terms of the prevalence of the risk factors and in terms of the global cardiovascular risk. CONCLUSION Using the global cardiovascular risk approach as a primary prevention measure could allow patients suffering from schizophrenia to be admitted earlier. Also, regularly reevaluating that risk could allow initiation of behavioral changes and/or important cardiovascular treatments.

Abstract
AIM The aim of this systematic revue of literature is to examine articles dealing with the narrative insight (patient's explanatory models of his difficulties) in patients suffering from schizophrenia. In addition to the theoretical interest of this work, it would make it possible to better adjust the clinical practices concerning the stories of patients about their disorders. METHOD A study was conducted using the databases ScienceDirect, Medline, PsychInfo and PubPsych using the key words "narrative insight", "cultural insight", "subjective insight", "narrative awareness", "mental illness", and "psychiatric disorder". This search by keywords led to eighty-six results; abstracts of all the articles were consulted. Then the authors selected and studied all articles corresponding to inclusion criteria and compared their results and reached agreement by consensus in case of difference. The theme of the study was to focus on the concept of narrative insight or any other close concept mentioning an explanatory model of mental and/or psychiatric disorders, moving away from the biomedical model. Nine articles were selected based on the inclusion criteria (articles published in peer reviewed journals, where the both the resume and article are accessible; articles dealing with narrative insight of people suffering from schizophrenia). RESULTS The authors of these articles agree that awareness of mental illness, insight, is a narrative act in which people give a personal meaning to their disorder. The most popular biomedical model used has many limitations and is the subject of many controversies. Results of the conducted study suggest considering narrative insight as adaptive strategies to mental illnesses. Indeed the process of narrative insight essentially consists in the patient adapting his life story to his conceptions and his values. To tell the story of one's own troubles with one's own values and beliefs gives meaning that helps protect identity and give back hope. This concept is considered to be dynamic and multidimensional. In addition, studies highlight its positive effects including the simultaneous presence of several models, which would have a greater favorable impact on the prognosis than the medical explanation alone. CONCLUSION It seems necessary to take into account the concept of narrative insight in order to evaluate insight of patients suffering from mental illness. This implies that the evaluation methods of insight as well as the clinical practice must evolve to adapt to the culture and subculture of the patient. This could have beneficial effects on the well-being of patients, therapeutic relations, access to treatment as well as psychiatric research, as well as limit controversies around this topic. It would be interesting to confirm this new conception of insight and the therapeutic relations by carrying out new studies as well as by starting to take it into account in patient care.

Abstract
BACKGROUND The combination of schizophrenia and diabetes mellitus presents a public health problem in the world. Several studies have been carried out for the analysis of this comorbidity, including prognostic factors. OBJECTIVE The objective of our study is to determine the risk factors associated with the comorbidity schizophrenia and diabetes mellitus. METHODS From a sample of 200 cases of schizophrenic patients hospitalized at the Sidi Chami psychiatric hospital of Oran in Algeria, we carried out a descriptive transversal and analytical study during the period of one year. RESULTS Our results are consistent with those of the different studies carried out in neighboring countries. Among the risk factors recorded in our study, we mention the age of 40 and over, divorce, dyslipidemia, high blood pressure, overweight and severe and moderate obesity, the age of schizophrenia of 30 to 40 years, the first-generation neuroleptic treatment and family history related to diabetes. While the male sex, celibacy and second-generation neuroleptics were found in the study as protective factors against the onset of diabetes mellitus in schizophrenic patients. CONCLUSION The factors associated with comorbidity schizophrenia and type 2 diabetes are manifold. These factors must be taken into account when introducing preventive behaviors that must be multidisciplinary in order to ensure better patient care.

Abstract
In his work « Phenomenology of Psychosis » Arthur Tatossian tends to report the basal alteration of patients to a constrained phenomenological reduction and deducts the drive of daily life as a sensitive point of the schizophrenic experience, vulnerability and mark of his destiny. This perspective reveals the challenge of the dynamics of human identity. Going beyond the spatial figure of a split, Alfred Kraus takes up the living format of the dynamics of « role », which regulates the relation of the subject to Self and others, and suggests to report symptoms and syndromes, another stake destined, to one of the variants dialectics of the balance between self and others. We return to the psychopathological intuition of the origins of psychiatric phenomenology to relate the disorder to a particular experience of the lived time, a modification of the relations between the temporal ecstasies that Bin Kimura describes as an excessive « futurisation » by accentuation of the possible and impatience to exist. These approaches inform in a novel way the system of care, and far from advocating objective therapeutic applications, generate implications that can enrich and enhance care projects.

Abstract
The concept of staging is applied in medicine since many years, in order to better adapt treatment to patients' needs. Some authors have suggested one should also apply this concept to psychiatric disorders. If this approach seems to make sense, concrete progress in the domain are still limited. It is in the field of psychosis that most development have occurred, in the favorable context of early intervention programs. Some very detailed models have recently been proposed where successive stages of psychotic disorders are defined and corresponding treatment options are proposed. However, the limited reliability of clinical diagnoses systems and the absence of biomarkers allowing a more objective delineation of these various stages still hampers the concrete application of such strategies. Despite these limitations, the staging concept has already started to modify the mental health offer, especially for adolescents and young adults, for example through the development of the Headspace centers in Australia and other countries. These centers constitute accessible entry point for help seekers with mental health issues where treatment is defined according to the stage of illness. If such programs seem promising, a better understanding of the mechanisms underlying the development of psychiatric disorders seems important in order to facilitate the identification of stages and define the nature of the treatment needed for each of them, considering such knowledge has been the crucial for the development of the staging model in somatic disorders.

Abstract
Despite the lack of progress in the curative treatment of mental illness, especially schizophrenia, the accumulation of neuroscience data over the past decade suggests the re-conceptualization of schizophrenia. With the advent of new biomarkers and cognitive tools, new neuroscience technologies such as functional dynamic connectivity and the identification of subtle clinical features; it is now possible to detect early stages at risk or prodromes of a first psychotic episode. Current concepts reconceptualizes schizophrenia as a neurodevelopmental disorder at early onset, with polygenic risk and only symptomatic treatment for positive symptoms at this time. The use of such technologies in the future suggests new diagnostic and therapeutic options. Next steps include new pharmacological perspectives and potential contributions of new technologies such as quantitative system pharmacology brain computational modeling approach.

Abstract
INTRODUCTION The improvement of prescription constitutes a major challenge for public health. In France, medication is the third cause of serious adverse reaction. The report of the Parliamentary Commission for Evaluation of Health Policy on adequate use of psychotropics mentions their overconsumption. Promoting practices' dissemination and guidelines' respect is one of the missions of the referral psychosocial rehabilitation centers. Therapeutic advice that is offered consists of suggestions for revision in the patient's treatment with the aim of improving the patient's health. To our knowledge, to date no study has focused on the evaluation of therapeutic advice in psychiatry. The present study aimed at analyzing benefits of therapeutic advice for the patients. To this end: (1) a state of things related to actual practices was carried out: psychotropics prescriptions' problems and therapeutic advice proposed by psychiatrists (quantitative and qualitative assessment); (2) the impact of advice on prescription was assessed; (3) patients' benefits were identified. METHOD This monocentric trial was carried out at the referral psychosocial rehabilitation center of Lyon. This audit was a retrospective observation of electronic medical records (software CortexteNet V2.6). This project was developed by a multidisciplinary staff (pharmacists and psychiatrists) during summer 2015. All patients treated in this center between September 2010 and December 2014 were included. The collection of data was made by two auditors (pharmacist students) thanks to a collection grid with six parts: identification and epidemiology of patients with therapeutic advice, coding tips, benefits, quantitative and qualitative assessment of prescriptions before and after advice. RESULTS Of the 601 records explored during this study, 66 advices (8.3% of patients) were identified. Patients concerned by therapeutic advice were mainly men with schizophrenia between 35 and 40 years, living in a town and addressed by public psychiatrists. Advice was taken into account in 81.7%, partially in 8.1%, and was beneficial in 97%. The main benefits were clinical improvement (48.5%) and reduction of adverse drug events (36.4%). There were no statistically significant differences between prescriptions (quantitatively and qualitatively) before and after therapeutic advice. CONCLUSION In most cases, prescriptions of psychotropics were adequate since only 66 advices (8.3% of patients) were given. Psychosocial rehabilitation centers give medication prescribing advice and promote respect of the guidelines. The collaboration between rehabilitation's psychiatrists and other psychiatrists optimizes patient management. It reduces iatrogenic disorders and improves quality and safety of care. Very few studies deal with the prescription of psychotropics in adult psychiatry. This work highlights the positive effect of therapeutic advice for this population. Further controlled studies should clarify the benefits of therapeutic advice.

Abstract
INTRODUCTION Olanzapine pamoate has a higher cost of treatment than the oral form and requires administration in a hospital setting (unlike other long-acting antipsychotics), and the cost-effectiveness of this treatment may be questioned. Many scientific societies and national health systems are increasingly interested in the pharmacoeconomic impact of health products. The search for efficacy of a treatment can be done in two ways: medico-economic modeling studies or observational studies i.e. randomized controlled trials or mirror studies. The models are based on theoretical models from published clinical data simulating the course and evolution of patient health conditions, which benefit from a particular therapeutic strategy. Even if the design of observational mirror studies makes it possible to get closer to the clinical reality by observing the patient before and after the initiation of the treatment, the majority of the pharmacoeconomic studies published on olanzapine pamoate are modeling works that do not reflect actual conditions of care. The Guillaume Régnier Hospital Center in Rennes has a large cohort of patients treated with olanzapine pamoate: 121 instauration treatments are recorded from April 1, 2010 to Mars 1, 2015. The objective of this study is to evaluate the cost-effectiveness of olanzapine pamoate in actual clinical practice. METHODS This is a one-year cost-effectiveness retrospective observational mirror-image study of a cohort of 52 patients with schizophrenia who were treated for at least three months with olanzapine pamoate. The primary efficacy endpoint is the differential in the number of full-time hospitalizations before and after the introduction of olanzapine pamoate versus the hospital cost differential. The secondary criteria are the difference of the number of the days spent in hospital and the number of outpatient consultations between the year preceding the injection and the year following it. The results were calculated on the general cohort and within 2 subgroups: patients treated for more than one year and those receiving less than one year of treatment with olanzapine pamoate. RESULTS Fifty-two patients were included (median age=35 years, sex ratio H/F=2.7) and only 38.5% discontinued treatment. For patients who maintained long-acting treatment, they received a dosage of 25mg oral olanzapine (min=7.5mg, max=60mg), 5mg more medially than the group having stopped the olanzapine pamoate (20mg; min=10mg, max=40mg). The majority of these patients were receiving off-label authorized marketing doses of oral olanzapine, whereas 22% of them had off-label dosages of olanzapine pamoate. The main causes of discontinuation were symptom persistence, loss of vision and the occurrence of adverse effects (including weight gain and sedation). Olanzapine pamoate significantly reduced the number of hospitalizations compared to the previous management strategy (1 less hospitalization, P<0.001 in patients treated more than one year and in the general cohort). As a logical consequence the number of hospitalization days in day care increased after the establishment of this long-acting antipsychotic with hospital reserve status (18 in median; min=0, max=159). We observed a non-statistically significant tendency of decrease in the number of days of full-time hospitalization and an increase in the number of ambulatory procedures, particularly in patients who have maintained the treatment for one year. This efficiency had a non-significant additional cost of €3361 per year. There was an average multiplication by 8,5 of the drug cost a year later in the general cohort (5.5 in the group of patients treated less than one year and 10.4 in the group of patients who maintained it a year). There was a 23,2% average increase in the cost of hospitalization in the general cohort (3.75 % in patients who maintained treatment compared to 48.9% in patients who discontinued treatment). CONCLUSION By its mirror design, the study was placed in real conditions of care of the patient with schizophrenia. A total of 61.5% of patients maintained treatment with olanzapine pamoate for a minimum of one year. This APAP is more effective without significantly increasing the cost compared to the previous therapeutic strategy (including oral olanzapine). The additional cost is partly due to the administration restriction in a hospital setting in relation to risk of Post-Injection Delirium/Sedation Syndrom (PDSS). There is currently no acceptable efficiency limit. The results of this cost-effectiveness analysis cannot be extrapolated to the other long-acting antipsychotics since it is the only one with hospital reserve status. The current limitations of medico-economics in psychiatry derive from the heterogeneity of clinical forms and the management of mental pathologies.

Abstract
OBJECTIVE This study aims to determine whether it is possible to identify clinical profiles at risk of violent behaviors (VB) in the early phase of psychotic disorders, on the basis of the main dynamic psychopathological risk factors and describe characteristics of the groups with highest levels of violent behaviors. METHOD A total of 265 patients, aged 18 to 35, treated at the Treatment and early Intervention in Psychosis Program (TIPP-Lausanne), a specialized early psychosis program, were included in this study. We conducted a latent-class analysis and a discriminative analysis on the basis of the main dynamic VB risk factors: substance use disorder, impulsivity, positive symptoms, insight, aggression, hostility, anger, emotional instability and adherence to treatment. These factors were evaluated by specialized scales and on the basis of the Positive and Negative Syndrome Scale (PANSS). VB were restricted to physical aggression against people, defined as "serious violence". They were assessed on the basis of a questionnaire listing violent offenses (Swiss Criminal Code) and VB such as assault and battery, information through the forensic psychiatric services and on the basis of the Staff Observation Aggression Scale (SOAS-R scale) during inpatient treatment phase. RESULTS Four heterogeneous subgroups were identified with respect to the studied clinical characteristics, including two groups with high rates of VB. The first group, comprising 46% of patients with VB, is distinguished by the prevalence of a range of dimensions related to hostility, impulsivity and emotional instability, associated with high levels of substance abuse and positive symptoms. These clinical dimensions are very significant at the statistical level, since they explain 70% of the construction of subgroups (discriminant analysis). The second group with 37% of patients with VB, is characterized by a lack of insight, lack of adherence to treatment and substance use. These two clinical profiles could increase the impairment of cognitive, functional and relational abilities and contribute to the development of VB in this early phase of psychosis. The third subgroup, with a violent behaviors rate of 28.6%, is distinguished by its high proportion of diagnoses of substance abuse (100%) and women (54%). A last subgroup of patients, the largest quantitatively, has a low proportion of VB (15%) and the lowest levels on the studied factors, suggesting that the majority of patients with this profile commit few VB. CONCLUSION Our results show that it is possible to identify groups at risk of violent behaviors during the early phase of psychosis on the basis of clinical characteristics that may evolve and therefore be the focus of preventive care. These results highlight the need to target substance use, impulsivity and lack of insight at follow-up in order to prevent VB.

Abstract
OBJECTIVE The aim of the study was to estimate the cost-effectiveness ratio of aripiprazole once-monthly compared to once-monthly injectable paliperidone palmitate in the treatment of schizophrenia in France on the basis of results and data from the QUALIFY study. METHODS Consumed resources data measured with a dedicated questionnaire and results on the quality of life scales from the QUALIFY study were combined with French standard unit costs of each collected consumed resources during QUALIFY to estimate the cost-effectiveness ratios of the two products. Multivariate sensitivity analyses were performed to test the combined impact of the different assumptions. RESULTS Findings of the study showed greater efficacy on the quality of life (QLS) and psychiatric evaluation scales (CGI-S and CGI-I) observed in QUALIFY of aripiprazole compared with paliperidone palmitate. Findings also suggest a trend (P=0.0733) in the reduction of total costs linked to a statistical decrease (P<0,0001) in drug costs in the aripiprazole group. These findings are reinforced by the probabilistic sensitivity analyses. CONCLUSION Aripiprazole appeared to be more cost-effective than paliperidone palmitate in the French context. Limits of this study are mainly related with the duration of the clinical trial and to assumptions on the transposability of measured consumed resources in the international clinical trial to the French healthcare system.

Abstract
OBJECTIVES The present article is a synthesis of the first 10 years of follow-up of the FondaMental Academic Center of Expertise for Schizophrenia (FACE-SZ) cohort. METHODS More than 700 community-dwelling stabilized subjects have been recruited and evaluated to date. The mean age was 32 years with 75 % males, the mean illness duration was 11 years, the mean age at illness onset was 21 years, the mean duration of untreated psychosis was 1.5 years and 55 % were current daily tobacco smokers. RESULTS The major findings of the FACE-SZ cohort may be summarized as follows: the metabolic syndrome is twice more frequent in schizophrenia as compared to the general population and is not correctly assessed and treated; cognitive disturbances have been found in benzodiazepine consumers and in patients with chronic low-grade peripheral inflammation; major depressive disorder (MDD) is a common current comorbid condition in about 20% of the subjects at the evaluation. MDD is associated with impaired quality of life and with increased nicotine dependency in SZ daily tobacco smokers. Improving depression and negative symptoms may be the most effective strategies to improve quality of life in schizophrenia; the duration of untreated psychosis is much longer in cannabis smokers and in subjects with an age at illness onset<19 years. Adherence to treatment is diminished in subjects who report a subjective negative feeling after treatment intake independent of objective side effects (extrapyramidal syndrome and weight gain). Akathisia has been found in 18% of the subjects and has been associated with antipsychotic polytherapy. CONCLUSIONS In the light of these results, some recommendations for clinical care may be suggested. The early detection of schizophrenia should be specifically increased in adolescents and/or cannabis smokers. All patients should be administered a comprehensive neuropsychological evaluation at the beginning of the illness and after stabilization under treatment. Improving metabolic parameters and lifestyle (diet and physical activity) should be reinforced. The benefit/risk ratio of benzodiazepine and antipsychotic polytherapy should be regularly reevaluated and withdrawn as soon as possible. If MDD remains underdiagnosed and undertreated, improving depression may strongly improve the quality of life of SZ subjects. In the end, Cognitive Remediation Therapy and anti-inflammatory strategies should be more frequently included in therapeutic strategies.

Abstract
Schizophrenia is a severe chronic mental disorder that mainly manifests by positive symptoms, negative symptoms, disorganized behavior and thought and cognitive impairments. Taken together, these symptoms have substantial impact on quality of life, well-being and functional outcome. Patients with schizophrenia have dramatically higher levels of cardiovascular and metabolic morbidity than the general population due to poor physical fitness and to sedentary lifestyle. They have a reduced life expectancy, and an excess mortality being two or three times more than that in the general population. Moreover, despite major therapeutic advances in the overall management of these patients, some symptomatic dimensions, and more specifically the negative and cognitive ones, remain to be resistant to the usual pharmacological approaches. Moreover, antipsychotics can also reinforce the global cardiovascular risk due to side effects and low neurometabolic tolerance. The benefits of physical activity on health are now well described in the general population and in many medical diseases. More recently, physical activity has also found its place as an adjuvant therapy in severe mental illnesses, particularly in schizophrenia. In the literature physical activity programs, in addition to pharmacological treatments, appear to be feasible in patients and improve both physical and mental health as well as functional outcome. Clinical benefits of physical activity would be underpinned by biological and cerebral mechanisms, which remain unclear. In this review, we propose to present a state of the art and to present an update of the interests of physical activity in the management of patients with schizophrenia. We emphasize the clinical benefits of physical activity regarding the different symptomatic dimensions and its impact specifically on cognitive deficits. Finally, we describe the various underlying pathophysiological mechanisms in particular in the neurobiological, cerebral and physiological fields. We then discuss the barriers, facilitators and motivating factors towards physical activity to enhance health promotion initiatives, to optimize resource allocation when delivering physical activity programs in clinical practice, and to maximize physical activity participation. Physical activity appears to be an original and novel adjunctive therapeutic approach in the management of patients with schizophrenia and would both reduce schizophrenic symptoms and act like pro-cognitive therapy, improve quality of life and long-term functioning in daily life and reduce cardiovascular comorbidities. However, efforts are still needed to increase the motivating factors and adherence towards physical activity participation for people with schizophrenia.

Abstract
OBJECTIVES Delusional misidentification syndromes (DMS) correspond to the delusional belief of misidentification of familiar persons, places or objects and to the conviction that they have been replaced or transformed. Several cases of patients who developed violent behavior while suffering from DMS have been published. This led some authors to consider patients with DMS at risk of violence. However, only a few studies have focused on the potential relationship between violence and DMS. The aim of our study was to explore this relationship with a literature review of published cases of patients having committed violent acts associated to DMS. METHODS A systematic literature search was conducted on PubMed up to January 2017 using the following term combination "misidentification" and "violence" Fifteen cases of patients with DMS who had committed violent acts were identified. The data from these descriptions were analyzed and synthetized. RESULTS Most of the patients were men with a diagnosis of schizophrenia and Capgras syndrome. Acts of violence were severe with a relatively high number of murders or attempted murders. For half of the patients these violent acts were perpetrated with weapons. Victims were regularly the patient's family members and the assaults were usually not planned. Delusional syndromes often progressed for several years. Importantly, substance abuse, which is known to increase the risk of violence in patients with schizophrenia, was only observed in two patients. CONCLUSION DMS are associated with several risk factors of violence, such as a diagnosis of schizophrenia, specific delusions including megalomania, persecution, negative affects and identified targets. Despite this risk for severe violence, there are no existing guidelines on how to assess and treat DMS in schizophrenia. Accordingly, we propose (1) the establishment of formal diagnostic criteria, (2) the development of rigorous research on these syndromes and (3) the integration of DMS in assessment of violence risk in schizophrenic patients.

Abstract
OBJECTIVES Video games and virtual reality have recently become used by clinicians for training or information media or as therapeutic tools. The purpose is to review the use of these technologies for therapy destined for schizophrenia patients. METHODS We conducted a review in October 2016 using Pubmed, Scopus and PsychInfo using the following Medical Subject Headings (MESH): "video games", "virtual reality" and "therapy, computer-assisted/methods", each associated with "schizophrenia". Papers were included in the review if: (a) they were published in an English, Spanish or French-language peer-reviewed journal, (b) the study enrolled patients with schizophrenia or schizo-affective disorder, (c) the patients used a therapeutic video game or therapeutic virtual reality device. RESULTS Eighteen publications were included. The devices studied are mainly therapeutic software developed specifically for therapeutic care. They can be classified according to their therapeutic objectives. These targets corresponded to objectives of psychosocial rehabilitation: improvement of residual symptomatology, cognitive remediation, remediation of cognition and social skills, improvement of everyday life activities, support for occupational integration. Very different devices were proposed. Some researchers analysed programs developed specifically for patients with schizophrenia, while others were interested in the impact of commercial games. Most of the studies were recent, preliminary and European. The impact of these devices was globally positive, particularly concerning cognitive functions. CONCLUSIONS Computer-assisted therapy, video games and virtual reality cannot replace usual care but could be used as adjunctive therapy. However, recommending their use seems premature because of the recent and preliminary character of most studies. Moreover, a link is still lacking between this field of research in psychiatry and other fields of research, particularly game studies. Finally, it might be interesting to analyse more precisely the neuropsychological impact of existing commercial games which could potentially be useful for psychosocial rehabilitation.

Abstract
BACKGROUND Electroconvulsive therapy is indicated in cases of catatonic schizophrenia following a failure of the challenge test with lorazepam or Zolpidem®. Some patients need maintenance treatment with ECT. Repetitive Transcranial Magnetic Stimulation (rTMS) and anodal Transcranial direct-current stimulation (tDCS) might be effective against catatonia. OBJECTIVE Consider an alternative to ECT for a refractory patient. REVIEW Twenty-one articles were identified mainly based on case reports series were found using search on Medline, Google Scholar, PsychInfo, CAIRNS. Key words were:"catatonia", and "rTMS", and more generally with"ECT","tDCS","Zolpidem®". At the end there were only six case reports with rTMS and three with tDCS. We discussed the alternative to ECT and follow up rTMS strategies illustrated by these case reports. FINDINGS Patients mean age was 35; numbers of previous ECT vary from zero to 556; the most common motor threshold (MT) is 80%, with two patients with 110%, the most common treatment placement is L DLPFC. In one of them, ECT was the only acute-state or maintenance treatment effective in this patient, who underwent 556 ECT sessions over 20 years. High-frequency rTMS was considered as a possible alternative, given the potential adverse effects of chronic maintenance ECT in a patient with comorbid epilepsy. rTMS treatment was 3-4×/week and over time extended to once every two weeks. A persistent objective improvement in catatonia was observed on the Bush-Francis Catatonia Rating Scale. CONCLUSION rTMS is helpful for acute and maintenance treatment for catatonic schizophrenia who both failed multiple pharmacologic interventions and had safety concerns with continuing maintenance ECT. Clinicians should consider rTMS as a potential treatment option for refractory catatonia.

Abstract
INTRODUCTION The concept of symptomatic and functional remission represents an important challenge in the care of the mentally ill, particularly in patients with schizophrenia. Operational criteria for symptomatic remission in schizophrenia have been proposed by Andreasen et al. (2005). Over the last decade, these criteria have been widely validated; however few studies have been conducted outside developed countries. Moreover, the association of symptomatic remission with functional outcome has not yet been established in developing countries including Tunisia, as there may be variability in the social and familial environment. OBJECTIVES To determine the frequency and associated factors of symptomatic remission in a sample of Tunisian out-patients with schizophrenia and to explore the relationship between symptomatic remission and some indicators of social functioning. METHODS A cross-sectional study was carried-out on 115 out-patients with schizophrenia (87 males, 28 females, mean age=37.56±10.2 years) in the psychiatry department of the university hospital in Monastir (Tunisia). Nearly all of the patients (98.26%) had been hospitalized at least once in a psychiatric unit. The last hospitalization dated back to 39 months on average (range=6 months to 16 years). Symptomatic remission was assessed by the eight core items of the positive and negative syndrome scale (PANSS). These are the items P1 "Delusions"; P3 "Hallucinatory behavior" and G9 "Unusual thought content" for the positive dimension, the items P2 "Conceptual disorganization" and G5 "Mannerism and disorders of posture" for the disorganization dimension and the items N1 "Blunted affect", N4 "Social withdrawal" and N6 "Lack of spontaneity and flow of conversation" for the negative dimension. A score of mild or less on all eight-core symptoms constitutes symptomatic remission. This symptom level should have been maintained for six months. The social functioning was assessed by the Social and Occupational Functioning Assessment Scale (SOFAS) and the Social Autonomy Scale (SAS) exploring personal care, management of daily life, resource management, the relationship with the outside and the emotional life and relationships social. A multivariate analysis using a binary logistic regression was conducted with as a dependent variable "symptomatic remission" and as explanatory variables the associated variables with symptomatic remission in bivariate analysis with age and gender. RESULTS The symptomatic remission was observed in 50.4% of patients. The items corresponding to positive dimension (P1, P3 and G9) and the item P2 "conceptual disorganization" had a better predictive value of symptomatic remission. After multivariate analysis, the associated factors of symptomatic remission were the acute of onset (P=0.026), the low score of negative symptoms during the last hospitalization (P=0.017) and the episodic course (P<0.0001). However, age or gender of the patients, educational or socioeconomic level, psychiatric family history, age of onset, duration of untreated psychosis, number and duration of previous hospitalizations, antipsychotic treatment dosage were not associated with symptomatic remission in our sample. The mean score of the SOFAS was 48.47±14.44, and the mean score of the SAS was 56.6±16.84. A significant association was shown between the SOFAS score and the symptomatic remission (P<0.0001) and between the SAS score and the symptomatic remission (P<0.0001). Moreover, a significant association was found between symptomatic remission and occupational activity (P=0.03). CONCLUSION The frequency of symptomatic remission according the PANSS criteria in our sample is above the average of the reported rates in literature (30 to 60%). This can be explained by the frequency of symptomatic remission in outpatient versus inpatients, or in relation to the notion of a more favorable course of schizophrenia in developing countries, although this notion is controversial. Remitter patients had significantly an acute onset of disorders, a low score of negative symptoms during the last hospitalization and an episodic course. They also showed a significant trend for better social functioning. In fact, a significant association was shown in our sample between symptomatic remission and social functioning. These results suggest that the concept of remission has important implications for the treatment of patients with schizophrenia.

Abstract
INTRODUCTION Schizophrenia is a disorder affecting 1% of the population and is associated with severe functional impairment. Negative symptoms are responsible for the majority of this impairment, and many patients with schizophrenia have negative symptoms. However, their evaluation is still a challenge. Thus, standardized assessments are needed to facilitate identification of these symptoms. Many tools have been developed, but most are based on observer ratings. Self-evaluation can provide an additional outcome measure and allow patients to be more engaged in their treatment. The Self-evaluation of Negative Symptoms (SNS) has been developed recently. This is a remarkably understandable instrument for patients with schizophrenia as it allows them to readily complete it without assistance, providing information with respect to their own perception of negative symptoms. The SNS is a self-assessment that permits patients to evaluate themselves in 5 dimensions of negative symptoms. This validation study for the SNS revealed good psychometric properties alongside satisfactory acceptance by patients. AIM This study was to confirm the validation of the French version of the self-evaluation of negative symptoms (SNS). METHODS Patients with schizophrenia or schizoaffective disorder according to the DSM-IV-R, with a stable regimen of anti-psychotic drugs for the last two months, aged more than 18 years old were eligible for the study. Symptoms were rated using the SNS, the Scale for the Assessment of Negative Symptoms (SANS), the Calgary Depression Scale for Schizophrenics (CDSS), the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impression and Parkinsonism. Patients were asked to fulfill the SNS twice, 6 weeks apart. RESULTS Sixty patients were evaluated. Cronbach's coefficient (α=0.8) showed good internal consistency. The SNS significantly correlated with the SANS (r=0.6), the negative sub-score of the BPRS (r=0.6) and the Clinician Global Impression on the severity of negative symptoms (r=0.7). SNS scores did not correlate with level of insight (r=0.08) or Brief Psychiatric Rating Scale positive sub-scores (r=0.2). SNS scores correlated with CDSS scores. However, we did not find correlation between the first item of the CDSS which evaluates depression and the "diminished emotional range" sub-score of SNS. The test-retest of SNS revealed no changes of scores at two evaluations 6 weeks apart. CONCLUSION The acceptance by patients of the SNS was excellent. The French version of the SNS demonstrated a good internal consistency, good convergent validity and good discriminant validity. The study demonstrates the ability of patients with schizophrenia to accurately report their own experiences. Self-assessments of negative symptoms should be more widely employed in clinical practice because they may allow patients with schizophrenia to develop appropriate coping strategies.

Abstract
Psychiatric disorders (more specifically mood disorders and psychosis) represent the 1st cause of disability among young people. Unemployment rate between 75 to 95% for the person with schizophrenia. It is correlated to poor social integration and bad economic status, worse symptomatology loss of autonomy as well as global bad functioning. It is responsible of more than half of the overall cost of psychosis. The onset of most of psychiatric disorders occur between the age of 25 and 35 years old, a critical time in young adult life when they should build their professional as well as social future. Without appropriate care, young adult are unable to build satisfactory emotional relationships, continue their studies, live independently or fit into life. They are frequently dependent on their environment. They also have an increased suicide rate and frequent comorbid substance abuse. Despite this context, their care pathway is often marked by a delay or premature stop of care, drug treatments not always suitable and a lack of specific relay post-hospitalization regarding continuity of professional training or studies. All factors impacting future employability of adolescents. Furthermore they spend most of their time in school and school plays a key part in an individual's development including peer relationships, social interactions, academic attainment, cognitive progress, emotional control, behavioral expectations and physical and moral development. These areas are also reciprocally affected by mental illness. The initial phases of FEP are characterized by impaired academic performance, change in social behaviors and increasing absences from school, reflecting the prodrome of the illness that leads to disengagement from education. Functional decline often precedes onset of clinical symptoms and many adolescents and young adults are therefore isolated from school before their illness is recognized. School support staff may fail to recognize those who are functionally impaired because of evolving FEP although school is a key setting for promoting positive mental health, fostering resilience, detecting and responding to emerging mental ill health. So, people with psychotic illness have low levels of secondary school completion. School dropout has been defined as leaving education without obtaining a minimal credential, most often a higher secondary education diploma. In France, the school is compulsory up to the age of 16. Consequences are significant: among young people without a degree out of initial training for one to four years and present on the labour market, 47% are unemployed. School dropout depends on a number of factors, including grades, family and social environment and the relationship with the school, but also the emergence of psychiatric disorders. For first episode psychotic patients, age of onset, lack of family support, longer duration of psychosis, levels of premorbid global functioning and education, negative and cognitive symptoms, addictions, depressive comorbidities and stigma plays an important role in school dropout. However, young adults have historically received less treatment than expected considering prevalence of mental illness at that age. In the last few decades, early intervention programs for psychosis have been developed all around the world in order to promote rehabilitation and prevent long-term disabilities. Early intervention programs focus on the special needs of young people and their families and engage in some form of assertive community treatment, which attempts to treat patients in the community rather than using inpatient services. For early intervention in psychosis programs, the goal is to keep patients engaged with treatment, prevent them from further psychotic episodes and hospitalizations and promote rehabilitation. The additional services of an early intervention program include staff specialized in psychosis treatment, family/group/individual counseling sessions, assertive case management, and low-dose second generation anti-psychotics. In these programs, psychiatric rehabilitation practitioners already use individual counseling and supported education programs (SEd) to improve postsecondary educational outcomes. The goals of SEd are for individuals with serious mental illness to successfully be able to set and achieve an educational goal (e.g., training certificate or degree), to improve educational competencies (literacy, study skills, time management), to navigate the educational environment (e.g., applications, financial assistance), and to improve motivation toward completing educational goals. These approaches are often combined with efforts to support transitions to sustainable employment. Current evidence of these interventions are weak with limited information on specific difficulties experienced by young adults with FEP in educational tasks. Adaptive strategies are needed by young adults with FEP to succeed in educational settings but most studies do not explore it with rigorous methodology. However, common SEd components emerge: specialized and dedicated staffing, one-on-one and group skill-building activities, assistance with navigating the academic setting and coordinating different services, and linkages with mental health counseling. Continued specification, and testing of SEd core components are still needed. It is important that occupational therapy researchers and practitioners develop, and evaluate effective interventions to improve education outcomes for young adults with FEP. The objective of this work is to define school dropout, assess causes and consequences of FEP. How to help young people to maintain education? We will detail measures to support the academic re-insertion in France.

Abstract
OBJECTIVES The association between schizophrenia and violence represents an important issue in psychiatry. Often highly publicized, violent acts raise the question of their detection, prevention, management and treatment. There is no single, direct and exclusive link between aggressiveness and the underlying psychiatric disorder. On the contrary, the processes underlying this violence are multiple and interlinked. In addition to static and dynamic risk factors, cognitive deficits play an important role in the genesis and maintenance of violent and aggressive behavior. METHODS Using recent data from the international literature and the main databases, we first clarify the role played by cognitive deficits in the violence of patients with schizophrenia. We then evaluate the place of psychosocial interventions such as cognitive remediation and social cognitive training in managing the violent and aggressive behavior of these patients. RESULTS Executive functions and working memory are the most studied neurocognitive functions in the field of violence in schizophrenia. Impulsivity, lack of cognitive flexibility, lack of adaptation and inhibition of automatic motor responses, and altered anger regulation may explain this relationship. Three main components of social cognition are associated with violent behaviors in schizophrenia: (1) the recognition of facial emotions through the inoperability of systems of "emotional monitoring", violent inhibition and recognition of informative facial zones; (2) the theory of the mind through the erroneous interpretation of the intentions of others; (3) the attributional style through the preferentially aggressive over interpretation of social situations and weak capacities of introspection. Overall, cognitive biases inhibit response in a socially acceptable manner and increase the risk of responding impulsively and aggressively to a stressful or provocative situation. In this context, we studied the place held by psychosocial interventions in the management of the violent and aggressive behaviors of these patients. Various cognitive remediation programs have shown their feasibility in people with schizophrenia and neurocognitive deficits with a history of violence as well as their effectiveness in reducing violence, mainly by reducing impulsivity. Similarly, specific programs dedicated to social cognitive training such as Social Cognition and Interaction Training (SCIT), Reasoning and Rehabilitation Mental Health Program (R&R2 MHP) and Metacognitive Training (MCT) have shown their positive impact on the control and reduction of global aggressive attitudes and on the numbers of physical and verbal aggressive incidents in schizophrenia. The improvement of social cognition would be achieved through the amendment of interpersonal relationships and social functioning. These interventions are effective at different stages of disease progression, in patients with varied profiles, on violent attitudes in general and on the number of verbal and physical attacks, whether for in-patients or out-patients. Beneficial effects can last up to 12months after termination of the study program. The interest of these interventions is preventive if the subject never entered in a violent register or curative in case of a personal history of violence. This type of care can be considered from a symptomatic point of view by limiting downstream the heavy consequences of such acts, but also etiologically by acting on one of the causes of violent behavior. Compliance with the eligibility criteria, carrying out a prior functional analysis and confirmation of the major impulsive part of the patient's violence are prerequisites for the use of these programs. Similarly, the early introduction of such therapies, their repetition over time and the integration of the patient into a comprehensive process of psychosocial rehabilitation will ensure the best chance of success. CONCLUSIONS Some cognitive impairments appear to have their place in the genesis, progression and maintenance of violent acts of individuals with schizophrenia. Their management thus opens new therapeutic perspectives such as cognitive remediation, still rarely used in this aim, to complement the action of the traditional care tools. However, further therapeutic trials are needed before considering cognitive remediation and social cognitive training as central care modalities in the therapeutic control of violence in schizophrenia.

Abstract
BACKGROUND Violence is a common issue in psychiatry and has multiple determiners. The aim of this study is to assess the psychotic inpatients' violence in association with the violence of the neighborhood from which the patients are drawn and to estimate the impact of this environmental factor with regard to other factors. METHOD A prospective multicenter study was led in nine French cities. Eligible patients were psychotic involuntary patients hospitalized in the cities' psychiatric wards. During their treatments, any kind of aggressive behavior by the patients has been reported by the Overt Aggression Scale (OAS). RESULTS From June 2010 to May 2011, 95 patients have been included. Seventy-nine per cent of the patients were violent during their hospitalizations. In a bivariate analysis, inpatient violence was significantly associated with different factors: male gender, patient violence history, substance abuse, manic or mixed disorder, the symptoms severity measured by the BPRS, the insight degree and the city crime rate. In a multivariate analysis, the only significant factors associated with the patients' violence were substance abuse, the symptoms severity and the crime rates from the different patients' cities. CONCLUSION These results suggest that violence within the psychotic patients' neighborhood could represent a risk of violence during their treatments.

Abstract
BACKGROUND The aim of the REDSIAM network is to foster communication between users of French medico-administrative databases and to validate and promote analysis methods suitable for the data. Within this network, the working group "Mental and behavioral disorders" took an interest in algorithms to identify adult schizophrenia in the SNIIRAM database and inventoried identification criteria for patients with schizophrenia in these databases. METHODS The methodology was based on interviews with nine experts in schizophrenia concerning the procedures they use to identify patients with schizophrenia disorders in databases. The interviews were based on a questionnaire and conducted by telephone. RESULTS The synthesis of the interviews showed that the SNIIRAM contains various tables which allow coders to identify patients suffering from schizophrenia: chronic disease status, drugs and hospitalizations. Taken separately, these criteria were not sufficient to recognize patients with schizophrenia, an algorithm should be based on all of them. Apparently, only one-third of people living with schizophrenia benefit from the longstanding disease status. Not all patients are hospitalized, and coding for diagnoses at the hospitalization, notably for short stays in medicine, surgery or obstetrics departments, is not exhaustive. As for treatment with antipsychotics, it is not specific enough as such treatments are also prescribed to patients with bipolar disorders, or even other disorders. It seems appropriate to combine these complementary criteria, while keeping in mind out-patient care (every year 80,000 patients are seen exclusively in an outpatient setting), even if these data are difficult to link with other information. Finally, the experts made three propositions for selection algorithms of patients with schizophrenia. CONCLUSION Patients with schizophrenia can be relatively accurately identified using SNIIRAM data. Different combinations of the selected criteria must be used depending on the objectives and they must be related to an appropriate length of time.

Abstract
The exact modalities of switching between two antipsychotics are rarely studied despite the high frequency of this issue in clinical practice. In this context, description of clinical cases may be enlightening. We report on three new cases of agitation after replacing a dopaminergic antagonist with aripiprazole. A literature review indicated no other predictive clinical feature associated with a higher risk of agitation than therapeutic history. In fact, patients who previously received a greater dose of antipsychotic are more at risk to present paradoxical agitation when switching to aripiprazole. This has led to the hypothesis of dopaminergic hypersensitivity: dopaminergic antagonists could increase the number of receptors to be activated by a partial agonist-like aripiprazole. In one of the cases described here, the patient had received aripiprazole two years previously without any particular side effects. The reintroduction of aripiprazole after a treatment by risperidone was followed by agitation. Other pharmacological hypotheses to explain this agitation involve cholinergic and histaminergic rebounds as well. The frequency of these paradoxical reactions is probably underreported, and psychiatrists should be more attentive to them. During the replacement, aripiprazole should be prescribed at the maximal posology from the start, and the previous antipsychotic should be maintained and slowly decreased in no fewer than four weeks.

Abstract
Mental health is an essential component of general health. Schizophrenia is a severe and chronic mental illness that affects higher brain functions. It is characterized by the presence of a mental dissociation, dampened or inappropriate affects, hallucinations and delirium. Schizophrenia has also a negative impact on oral health. As schizophrenia affects 1% of the population, every practitioner concerned with oral sphere will be confronted one day or another with a patient suffering from this disease. It is therefore important to acquire essential notions. The aim of our work was to make an update about factors that may affect oral health in patients with schizophrenia.

Abstract
In children and adolescents, psychotic disorders already represent one of the leading causes of disability-adjusted life years. During the past two decades, early detection of risk for psychosis has been intensively investigated, and in particular, predictive power for early signs of risk has been initiated and translated into clinical practice. In particular, the attenuated and transient positive symptoms of the ultra-high risk criteria, and the basic symptom criterion "cognitive disturbances", open promising routes to an indicated prevention and have recently been considered by the European Psychiatric Association (EPA) as diagnostic criteria of a psychosis-risk syndrome. The EPA recently provided evidence-based recommendations on the early detection of clinical high risk (CHR) for psychosis in patients with mental distress. In 2015, experts in the field of early detection conducted a meta-analysis reporting on studies examining conversion rates to psychosis in non-overlapping samples meeting at least one of the main CHR criteria: ultra-high risk (UHR) and/or basic symptoms criteria, examining the effects of potential moderators (different UHR criteria definitions, single UHR criteria and age) on conversion rates. In the 42 identified samples, comprising more than 4000 CHR patients who had been mainly identified by means of UHR criteria and/or the basic symptom criterion 'cognitive disturbances' (COGDIS), conversion rates showed considerable heterogeneity. While UHR and COGDIS criteria were related to comparable conversion rates until a 2-year follow-up, rates for COGDIS were significantly higher for follow-up periods beyond 2 years. Differences in onset and frequency requirements of symptomatic UHR criteria, or in their different consideration of functional decline, substance use and co-morbidity, did not seem to have an impact on conversion rates. The 'genetic risk and functional decline' UHR criterion was rarely met and only showed an insignificant pooled sample effect. However, age significantly affected UHR conversion rates with lower rates in children and adolescents. Although more research into potential sources of heterogeneity in conversion rates is needed to facilitate improvement of CHR criteria, six evidence-based recommendations for the early detection of psychosis were developed as a basis for the EPA guidance on early intervention in CHR states. The EPA guidance on early intervention aimed to provide evidence-based recommendations on early intervention in CHR states of psychosis, assessed according to the EPA guidance on early detection. The recommendations were also made by experts in the field of early intervention in psychoses and derived from a meta-analysis of current empirical evidence on the efficacy of psychological and pharmacological interventions in CHR samples. Eligible studies had to investigate conversion rate and/or functioning as a treatment outcome in CHR patients defined by the ultra-high risk and/or basic symptom criteria. In addition to analyses of treatment effects on conversion rate and functional outcome, age and type of intervention were examined as potential moderators. Based on data from 15 studies (n=1394), early intervention generally produced significantly reduced conversion rates at 6- to 48-month follow-up compared to control conditions. However, early intervention failed to achieve significantly greater functional improvements because both early intervention and control conditions produced similar positive effects. With regard to the type of intervention, both psychological and pharmacological interventions produced significant effects on conversion rates but not on functional outcome relative to the control conditions. Early intervention in youth samples was generally less effective than in predominantly adult samples. Seven evidence-based recommendations for early intervention in CHR samples have been formulated, although more studies are needed to investigate the specificity of treatment effects and potential age effects in order to tailor interventions to the individual treatment needs and risk status. Overall, age-related specificities and developmental transitions in the early detection and intervention in psychoses should be better accounted for in future research.

Abstract
After reminding the various phases of the development of molecules, this article will state the stages of commercialisation of treatments, underlining the FDA (Food and Drug Administration) and the EMA (European Medicine Agency) requirements. Like all the other treatments available in Europe and in the United States, the long acting injectable antipsychotics (LAI) have to prove their efficacy compared to placebo and their non-inferiority compared to a treatment of reference, usually the same molecule in the oral form. These criteria of efficacy have evolved over time. If initially classical criteria of symptomatic intensity (score on scale PANSS) were considered, criteria more adequate from a clinical perspective, such as relapse, but also related to functioning, quality of life and, more recently, costs-effectiveness have appeared. This evolution is probably due to several factors: vision on mental illness, progress in patient's rights and aspirations, but also the pregnant place of health costs recently taken in the evaluation of treatments. These modifications are also based on the indications of L.A.I., i.e. stabilized patients for whom the challenge is rehabilitation care more than the control of symptoms.
