The impact of parent history of severe mental illness on schizophrenia outcomes: results from the real-world FACE-SZ cohort.

Parent history of severe mental illness (PHSMI) may have long-term consequences in adult offspring due to genetic and early environmental factors in preliminary studies. To compare the outcomes associated in subjects with PHSMI to those in patients without PHSMI. The participants with schizophrenia and schizoaffective disorders were recruited in the ongoing FACE-SZ cohort at a national level (10 expert centers) and evaluated with a 1-day-long standardized battery of clinician-rated scales and patient-reported outcomes. PHSMI was defined as history of schizophrenia or bipolar disorders in at least one parent and was included as explanatory variable in multivariate models. Of the 724 included patients, 78 (10.7%) subjects were classified in the PHSMI group. In multivariate analyses, PHSMI patients had a better insight into schizophrenia and the need for treatment and reported more often childhood trauma history compared to patients without PHSMI. More specifically, those with paternal history of SMI reported more severe outcomes (increased childhood physical and emotional abuses, comorbid major depression and psychiatric hospitalizations). PHSMI is associated with increased risk of childhood trauma, major depressive disorder and psychiatric hospitalization and better insight in individuals with schizophrenia. Specific public health prevention programs for parents with SMI should be developed to help protect children from pejorative psychiatric outcomes. PHSMI may also explain in part the association between better insight and increased depression in schizophrenia.

Early-life factors associated with increased risk of disability pension in the national real-world schizophrenia FACE-SZ cohort study.

Among severe psychiatric disorders, schizophrenia has one of the highest impacts on professional and personal functioning with important indirect costs including disability pension allowance for the patients with the more severe forms of schizophrenia. To explore early-life factors associated with disability pension in schizophrenia. 916 patients were consecutively recruited at a national level in 10 expert centers and received a comprehensive standardized evaluation. Their disability pension status and early-life variables were reported from medical records and validated scales. Eight factors were explored: age, male sex, parental history of severe mental illness, childhood trauma exposure, education level, childhood ADHD, early age at schizophrenia onset and duration of untreated psychosis. 739 (80.7%) participants received a disability pension. In the multivariate model, early age at schizophrenia onset and low education level were associated with disability pension independently of age and sex while no significant association was found for parent history of severe mental illness, childhood trauma, childhood ADHD or duration of untreated psychosis. Low education level and early age at schizophrenia onset seem the best predictors of increased risk of disability pension in schizophrenia.

Towards an improved access to psychiatric rehabilitation: availability and effectiveness at 1-year follow-up of psychoeducation, cognitive remediation therapy, cognitive behaviour therapy and social skills training in the FondaMental Advanced Centers of Expertise-Schizophrenia (FACE-SZ) national cohort.

Psychosocial Interventions (PIs) have shown positive effects on clinical and functional outcomes of schizophrenia (SZ) in randomized controlled trials. However their effectiveness and accessibility remain unclear to date in "real world" schizophrenia. The objectives of the present study were (i) to assess the proportion of SZ outpatients who benefited from PIs between 2010 and 2015 in France after an Expert Center Intervention in a national multicentric non-selected community-dwelling sample; (ii) to assess PIs' effectiveness at 1-year follow-up. 183 SZ outpatients were recruited from FondaMental Advanced Centers of Expertise for Schizophrenia cohort. Baseline and 1-year evaluations included sociodemographic data, current treatments, illness characteristics and standardized scales for clinical severity, adherence to treatment, quality of life, a large cognitive battery, and daily functioning assessment. Only 7 (3.8%) received a PI before the evaluation, and 64 (35%) have received at least one PI during the 1-year follow-up. Having had at least one PI during the follow-up has been associated in multivariate analyses with significantly higher improvement in positive and negative symptoms (respectively p =0.031; p = 0.011), mental flexibility (TMT B, p = 0.029; C-VF, p = 0.02) and global functioning (p =0.042). CBT and SST were associated with higher cognitive improvements, while CRT was associated with clinical improvement. These results have not been demonstrated before and suggest that the effect of each PI is larger than its initial target. The present study has confirmed the PIs' effectiveness in a large sample of community-dwelling SZ outpatients at 1 year follow-up. Efforts to improve access to PI should be reinforced in public health policies.

Chronic low-grade peripheral inflammation is associated with ultra resistant schizophrenia. Results from the FACE-SZ cohort.

A high rate of patients with schizophrenia (SZ) does not sufficiently respond to antipsychotic medication, which is associated with relapses and poor outcomes. Chronic peripheral inflammation has been repeatedly associated with schizophrenia risk and particularly to poor responders to treatment as usual with cognitive impairment in SZ subjects. The objective of present study was to confirm if ultra resistance to treatment in schizophrenia (UTRS) was associated to chronic peripheral inflammation in a non-selected sample of community-dwelling outpatients with schizophrenia. Participants were consecutively included in the network of the FondaMental Expert Centers for Schizophrenia and received a thorough clinical assessment, including recording of current treatment. Current psychotic symptomatology was evaluated by the Positive and Negative Syndrome scale for Schizophrenia (PANSS). UTRS was defined by current clozapine treatment + PANSS total score ≥ 70. Functioning was evaluated by the Global Assessment of Functioning scale. High sensitivity CRP (hs-CRP) was measured for each participant as a proxy to define peripheral low-grade inflammation. 609 stabilized community-dwelling SZ subjects (mean age = 32.5 years, 73.6% male gender) have been included. 60 (9.9%) patients were classified in the UTRS group. In multivariate analyses, UTRS has been associated independently with chronic peripheral inflammation (OR = 2.6 [1.2-5.7], p = 0.01), illness duration (0R = 1.1 [1.0-1.2], p = 0.02) and impaired functioning (OR = 0.9 [0.9-0.9], p = 0.0002) after adjustment for age, sex, current daily tobacco smoking, metabolic syndrome and antidepressant consumption. Peripheral low-grade inflammation is associated with UTRS. Future studies should explore if anti-inflammatory strategies are effective in UTRS with chronic low-grade peripheral inflammation.

Tobacco smoking is associated with antipsychotic medication, physical aggressiveness, and alcohol use disorder in schizophrenia: results from the FACE-SZ national cohort.

Tobacco smoking is common in schizophrenia and is one of the main causes of premature mortality in this disorder. Little is known about clinical correlates and treatments associated with tobacco smoking in patients with schizophrenia. Still, a better characterization of these patients is necessary, in a personalized care approach. Aggressiveness and childhood trauma have been associated with tobacco smoking in general population, but this association has never been explored in schizophrenia. Our study examines the clinical and therapeutic characteristics of tobacco smoking in schizophrenia. 474 stabilized patients (mean age = 32.2; 75.7% male gender; smokers n = 207, 54.6%) were consecutively included in the network of the FondaMental Expert centers for Schizophrenia and assessed with valid scales. Current tobacco status was self-declared. Aggressiveness was self-reported with Buss-Perry Aggressiveness Questionnaire and Childhood Trauma with Childhood Trauma Questionnaire. Ongoing treatment was reported. In univariate analysis, tobacco smoking was associated with lower education level (p < 0.01), positive syndrome (p < 0.01), higher physical aggressiveness (p < 0.001), alcohol dependence (p < 0.001), and First Generation Antipsychotics (FGAs) use (p = 0.018). In a multivariate model, tobacco smoking remained associated with physical aggressiveness (p < 0.05), current alcohol dependence (p < 0.01) and FGA use (p < 0.05). No association was observed with childhood trauma history, mood disorder, suicidal behavior, psychotic symptom, global functioning or medication adherence. Patients with tobacco use present clinical and therapeutic specificities, questioning the neurobiological links between tobacco and schizophrenia. They could represent a specific phenotype, with specific clinical and therapeutic specificities that may involve interactions between cholinergic-nicotinic system and dopaminergic system. Further longitudinal studies are needed to confirm the potential efficacy of second generation antipsychotics (SGAs) on tobacco use in schizophrenia and to develop effective strategies for tobacco cessation in this population.

[The 10-year findings from the FondaMental Academic Center of Expertise for Schizophrenia (FACE-SZ): Review and recommendations for clinical practice]. / Centres Experts Schizophrénie, un outil pour le soin et la recherche : retour sur 10 ans d'expérience.

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.

Benzodiazepine long-term administration is associated with impaired attention/working memory in schizophrenia: results from the national multicentre FACE-SZ data set.

OBJECTIVE: The effect of benzodiazepine long-term administration (BLTA) in cognitive functioning of subjects with schizophrenia (SZ) has been partially explored to date. The objective was to assess BLTA-associated cognitive impairment with a comprehensive cognitive battery in a non-selected multicentric/national community-dwelling sample of stabilized SZ subjects. METHOD: 407 community-dwelling stabilized SZ subjects were consecutively included in the FondaMental Academic Centers of Expertise for Schizophrenia Cohort (FACE-SZ). Patients taking daily benzodiazepine were defined as BLTA+ as all patients examined by the Expert Center were clinically stabilized and under stable dose of treatment for at least 3 months. Each patient has been administered a 1-day long comprehensive cognitive battery (including The National Adult Reading Test, the Wechsler Adult Intelligence Scale, the Trail Making Test, the California Verbal Learning Test, the Doors test, and The Continuous Performance Test-Identical Pairs). RESULTS: In the multivariate analyses, results showed that BLTA was associated with impaired attention/working memory (OR 0.60, 95% confidence interval 0.42-0.86; p = 0.005) independently of socio-demographic variables and illness characteristics. Verbal and performance current IQ-[respectively, OR 0.98, 95% CI (0.96;0.99), p = 0.016 and 0.98, 95% CI(0.97;0.99), p = 0.034] but not premorbid IQ-(p > 0.05) have been associated with BLTA in a multivariate model including the same confounding variables. CONCLUSION: BLTA is associated with impaired attention/working memory in schizophrenia. The BLTA benefit/risk ratio should be regularly reevaluated. Alternative pharmacological and non-pharmacological strategies for comorbid anxiety disorders and sleep disorders should be preferred when possible. It seems reasonable to withdraw BLTA before the start of cognitive remediation therapy, as soon as possible, to improve the effectiveness of this therapy. Limits: the delay between the last benzodiazepine intake and testing, as well as the specific class of benzodiazepines (long half-life vs. short half-life), and the number of benzodiazepine daily intakes have not been recorded in the present study. The precise motive for BLTA prescription and sleep disturbances have not been reported, which is a limit for the interpretation of the present results.

Relationships between low-grade peripheral inflammation and psychotropic drugs in schizophrenia: results from the national FACE-SZ cohort.

Low-grade inflammation has repeatedly been associated with schizophrenia (SZ) and in particular with cognitive impairment. Female gender, overweight and tobacco smoking have been suggested as risk factors to increase inflammation while preclinical inconsistent findings have been found regarding the association with psychotropic drugs. The aim of this study was to explore if psychotropic drugs were associated with inflammation in SZ and to determine which psychotropic drug was associated with inflammation in stable SZ subjects while considering clinical confounding factors. Participants were consecutively included in the network of the FondaMental Expert Centers for Schizophrenia and received a thorough clinical assessment, including recording of current treatment. High-sensitivity CRP (hs-CRP) was measured for each participant as a proxy to define peripheral low-grade inflammation. The zero-inflated Poisson regression model estimated the relationship between low-grade inflammation and psychotropic drug. Four hundred and five stabilized, community-dwelling SZ subjects (mean age = 32.6 years, 74% male gender) have been included. In total, 148 participants (36.5%) were found with undetectable blood hs-CRP level. The probability of having an undetectable CRP was associated with a lower body mass index (p < 0.0001) and no cyamemazine add-on antipsychotic therapy (p = 0.001). The other 257 participants (63.5%) were found to have low-grade inflammation (hs-CRP > 0 mg/L). Low-grade inflammation was significantly associated with female gender (p = 0.004), higher body mass index (p < 0.0001), current tobacco smoking (p < 0.0001), clomipramine (p = 0.04), quetiapine (p < 0.0001) and hypnotic (p = 0.0006) consumption while decreased hs-CRP blood levels was associated with aripiprazole (p = 0.004) and valproate/valpromide (p = 0.03) consumption. The present study suggests that some psychotropic drugs (quetiapine, cyamemazine, clomipramine) may be associated with increased peripheral low-grade inflammation in SZ patients while others (aripiprazole, valproate) may be associated with decreased peripheral low-grade inflammation. These results should be replicated in SZ and non-SZ populations and the biological underpinnings should be further explored.

[Ability of French General Practitioners to detect common mental disorders identified using the Patient Health Questionnaire: Has this changed with the introduction of gatekeeping and registration with a chosen doctor?] / Détection par le médecin généraliste des troubles psychiatriques courants selon l'auto-questionnaire diagnostique le Patient Health Questionnaire : dix ans après, le dispositif du médecin traitant a-t-il modifié la donne ?

OBJECTIVES: The general practitioner (GP) is the most frequently consulted health professional by patients with common mental disorders (CMD). Yet approximately half of cases are not detected by the GP. Many factors linked to the patient, the doctor and the health care system influence detection. For example, detection rates are higher when patients are better known to their GP. On the other hand, patients visiting a different GP for reasons of dissatisfaction with previous care are more likely to be detected on the survey-day. In France, a form of gatekeeping was introduced in 2005 to encourage patients to register with a doctor (most often a GP) of their choice (known as the Preferred Doctor), responsible for care coordination and referral if necessary to secondary care. Visiting a different GP, other than for non-avoidable reasons (for e.g. GP unreachable, patient on holiday), is still possible but financially sanctioned with lower reimbursement rates. We aimed to compare GP detection rates before and after the introduction of this gatekeeping scheme. Patient service use behaviour such as doctor-shopping and GP referral to secondary care were also compared. METHODS: Two cross-sectional surveys using the same study methods were carried out 10 years apart. In 2003, 46 GPs and 1151 patients participated (approximately 25 patients per GP), with a 32.7% GP participation rate. In 2013, 38 GPs participated (of which 29 had participated in the previous study, with a 85.3% "recapture" rate) and 1133 patients (approximately 30 patients per GP). Patient participation rates were 89.8% and 67%, respectively. Patients completed self-report questionnaires in the waiting room of which the DSM-IV diagnostic criteria Patient Health Questionnaire (PHQ) and an adapted version of the Client Service Receipt Inventory (CSRI) on contacts with health care services in the previous six months. For each patient, the GP completed a questionnaire giving his rating of psychiatric illness on a five-point scale with his/her diagnosis for cases, and action undertaken. RESULTS: Of the patients, 27% and 25.4% had a CMD according to the PHQ (defined as a diagnosis of minor or major depression, panic attack, anxiety or somatoform disorder) in 2003 and 2013 respectively. Corresponding detection rates were 51% and 52.6%. Rates were highest for threshold disorders: panic disorder (69.4% and 79.9% in 2003 and 2013, respectively), major depression (75% and 63.3% in 2003 and 2013, respectively) and other anxiety disorders (69.1% and 78.8% in 2003 and 2013, respectively). In 2003, the GPs declared seeing 15.5% for the first time on the survey-day, compared to 9.6% in 2013 (P=0.006). Doctor-shopping declined between the two studies, from 18.4% to 12.1% for practical and mostly unavoidable reasons, and from 9.8% to 4.2% for dissatisfaction reasons (P<0.0001). Referral to specialist doctors increased from 9.7% in 2003 to 14.7% in 2013 (P=0.014). In 2013, on the survey-day, 94.8% of patients had registered with a Preferred Doctor and 81.2% were seeing this Preferred Doctor. In 2003, 93.5% of patients declared having a usual GP and 79.9% were visiting this GP on the survey-day. CONCLUSIONS: This is one of the first studies to report data from two repeated surveys carried out before and after a change in the health service organisation, with data collected from both the patient and the GP. We report relatively high GP detection rates for the two periods, with about 50% of CMDs, including subsyndromic conditions, detected by the GP. Rates are considerably higher for the threshold disorders. The overall detection rate did not increase as expected between the two studies. Detection is a complex topic, involving issues such as the suitability of applying categorical DSM-IV criteria diagnoses to primary care, the relevance of detecting subthreshold conditions and the ability of cross-sectional studies to correctly assess the ability of GPs to recognise cases. The introduction of gatekeeping with the choice of a Preferred Doctor has led to a decline in the frequency of doctor-shopping, whatever its reason, with patients no doubt being better known to the GP. Yet it appears most patients had already chosen a GP they were loyal to before the scheme, with a similar proportion of patients consulting their chosen GP or Preferred Doctor on both survey-days in 2003 and 2013, suggesting the scheme may to some extent only have officialised what already existed with respect to having a usual GP. The French reform still allows for doctor-shopping which can be considered as a positive aspect of the scheme: patients either dissatisfied with previous care or needing to change GP are thus able to "test" and choose the doctor that best suits their needs.

Chronic low-grade peripheral inflammation is associated with severe nicotine dependence in schizophrenia: results from the national multicentric FACE-SZ cohort.

Chronic peripheral inflammation (CPI) has been associated with cognitive impairment in schizophrenia (SZ). However, its sources remain unclear, more specifically it is not known whether tobacco smoking is a source of inflammation or not in SZ subjects. Moreover, nicotine (NIC), the major psychoactive compound of tobacco, shows strong anti-inflammatory properties in vitro, as well as inducing a severe biological dependence when administered repeatedly. The objective of the present study was to determine if CPI was associated with tobacco smoking and/or NIC dependence in schizophrenia. Three hundred and forty five stabilized community-dwelling SZ subjects aged 16 years or older (mean age = 32 years, 73% male) were consecutively included in the network of the FondaMental Expert Centers for Schizophrenia and assessed with validated scales. CPI was defined by a highly sensitive C-reactive protein (hsCRP) ≥3 mg/L. Current tobacco status was self-declared. Severe NIC dependence was defined by a Fagerstrom Test for Nicotine Dependence score ≥7. Overall, 159 (46.1%) were non-smokers, 117 (33.9%) and 69 (20%) were current tobacco smokers with, respectively, low and severe nicotine dependence. In a multivariate model, CPI remained associated with severe NIC dependence (29 vs 15%, OR = 2.8, p = 0.003) and body mass index (OR = 1.1, p < 0.0001), independently of socio-demographic characteristics and antidepressant intake. No association of CPI with low to moderate tobacco smoking dependence, number of daily smoked cigarettes, cannabis use, alcohol use or illness characteristics was found (all p > 0.05). CPI was associated with severe NIC dependence but not with tobacco smoking with low to moderate NIC dependence in SZ, independently of socio-demographic variables, body mass index, alcohol consumption and antidepressant intake. This result highlights the potential CPI consequences of the high prevalence of heavy tobacco smoking in SZ, indicating the importance of new therapeutic strategies for tobacco cessation in SZ.

Birth by cesarean section and schizophrenia: results from the multicenter FACE-SZ data-set.

Children born by cesarean section ("c-birth") are known to have different microbiota and a natural history of different disorders including allergy, asthma and overweight compared to vaginally born ("v-birth") children. C-birth is not known to increase the risk of schizophrenia (SZ), but to be associated with an earlier age at onset. To further explore possible links between c-birth and SZ, we compared clinical and biological characteristics of c-born SZ patients compared to v-born ones. Four hundred and fifty-four stable community-dwelling SZ patients (mean age = 32.4 years, 75.8 % male gender) were systematically included in the multicentre network of FondaMental Expert Center for schizophrenia. Overall, 49 patients (10.8 %) were c-born. These subjects had a mean age at schizophrenia onset of 21.9 ± 6.7 years, a mean duration of illness of 10.5 ± 8.7 years and a mean PANSS total score of 70.9 ± 18.7. None of these variables was significantly associated with c-birth. Multivariate analysis showed that c-birth remained associated with lower CRP levels (aOR = 0.07; 95 % CI 0.009-0.555, p = 0.012) and lower premorbid ability (aOR = 0.945; 95 % CI 0.898-0.994, p = 0.03). No significant association between birth by C-section and, respectively, age, age at illness onset, sex, education level, psychotic and mood symptomatology, antipsychotic treatment, tobacco consumption, birth weight and mothers suffering from schizophrenia or bipolar disorder has been found. Altogether, the present results suggest that c-birth is associated with lower premorbid intellectual functioning and lower blood CRP levels in schizophrenia. Further studies should determine the mechanisms underlying this association.

[Insight and psychiatric dangerousness: A review of the literature]. / Insight et dangerosité psychiatrique : revue de la littérature.

INTRODUCTION: Violence committed by individuals with severe mental illness has become an increasing focus of concern among clinicians, policy makers, and the general public, often as the result of tragic events. Research has shown in the past two decades an increased risk of violence among patients with mental disorder. Nevertheless, of those suffering from mental illness, perpetrators of other directed violence form a minority subgroup. The means by which there is this association between mental illness and violence has remained controversial. Factors such as positive psychotic symptoms, medication non-adherence, alcohol or psychoactive substance abuse and antisocial personality were found to be predictive of violence. Overall, literature provides support to the assertion that violent behavior of mentally ill patients is a heterogeneous phenomenon that is driven by multiple inter-related and independent factors. Furthermore, psychiatrists are often asked to predict an individual's future dangerousness, in a medical or a legal context. In the process of risk assessment of dangerousness, more focus has been placed on dynamic risk factor. In this context, lack of insight has established itself both as a part of violence risk models and as a clinical item in structured approaches to measure dangerousness. However, few studies have tested these associations. The main purpose of this paper is to review the literature concerning the relationship between insight and dangerousness and discuss the contributions of the insight in the assessment of dangerousness in patients with mental illness. We included twenty studies that evaluated the association between insight and variable such as physical or verbal violence, aggressiveness, hostility or sexual aggression. RESULTS: According to the findings of this review, the strength and specific nature of this relationship remain unclear due to considerable methodological and conceptual shortcomings, including heterogeneity in the definition and assessment of violence, a minority of prospective studies and the lack of systematic consideration of possible confounding variables. However, the ability of the patient to perceive their illness is an important element to be considered in assessing the dangerousness both medically and legally. Higher belief flexibility and lower confidentiality of individual judgment, which reflect greater cognitive insight, may be associated with a lower incidence of violence, in particular in schizophrenia by decreasing the degree of confidence related to psychotic symptoms. CONCLUSION: In the growing efforts to reduce stigma associated with mental illness, it is important to identify a subgroup of patients at risk of violence and provide them with targeted treatment. In this sense, it seems important in the future to continue in this field of research to determine if the lack of insight is a covariate of a worsened condition or a specific violence risk factor per se.

[The clinic of apathy in schizophrenia: a critical review of the issue]. / L'apathie dans la schizophrénie: une revue clinique et critique de la question.

INTRODUCTION: Today the concept of apathy is subject to many questions. This psychological state is present and predominant in different disorders such as neurodegenerative and psychiatric diseases or neurological acquired disorders. Apathy is a part of the clinical vocabulary, however, we can note that in the literature there remains confusion in its definition, and we can find an amalgam with other clinical symptoms. OBJECTIVES: The aim of this review is to provide a clarification of the concept of apathy in clinical practice in schizophrenia as well as to highlight the gaps that exist. LITERATURE FINDINGS: Apathy belongs to the negative symptoms of schizophrenia. For its understanding, it is necessary to define apathy as a multidimensional syndrome (cognitive, emotional, and behavioral) manifesting as a quantitative reduction of voluntary behaviors directed toward one or several goals. However, at present, we are witnessing a reductionist and simplistic conception of the syndrome of apathy and this especially in the Anglo-Saxon literature. Several authors reduce apathy to its behavioral component, so in other words, to avolition/amotivation. Avolition refers to a loss of self-initiated and spontaneous behaviors. In this definition only observable behavior is taken into account and not the underlying mechanisms (cognitive and emotional). In order to understand the syndrome of apathy, it is necessary to have a holistic and multidimensional outlook. Some authors have proposed diagnostic criteria for apathy by taking into account the different dimensions of apathy. Moreover not only is apathy confused with avolition, but it is also still difficult to distinguish it from depression. Apathy and depression share common clinical signs (i.e. loss of interest), but they also have distinct clinical signs (lack of motivation for apathy, and suicidal ideation for depression). Authors have shown that the presence of one symptom (apathy or depression) does not predict the presence of the other. An apathetic patient does not have to be necessarily in a depressive state and vice versa. However, to our knowledge, there is no data capable of distinguishing depression from apathy in schizophrenia, and knowing what is the part of one and the other when the patient has both symptoms. In addition, we can see that the confusion that persists between those two symptoms also stems from assessment tools. Indeed, some assessment tools such as the Montgomery and Asberg Depression Rating Scale (MARDS) have an apathy subscale. Therefore, this scale does not only evaluate depression. Regarding the assessment of apathy in schizophrenia, there are specific and nonspecific tools. Nonspecific tools define apathy differently. For this reason, authors have proposed to measure apathy by using analytic factors of negative symptoms. In this case, apathy is going to be assessed by the factor "motivation/pleasure" including anhedonia, asociality and avolition. This factor will provide the possibility of a better assessment of apathy. Concerning specific scales (like AES), there are gaps such as a lack of standardization in the execution and the quotation. Furthermore, no scale takes into account the factors causing apathy. CONCLUSION: Knowing the reasons for apathy is necessary because this syndrome is frequent in schizophrenia, and it is found in the different phases of this disease (prodromal, first episode psychosis, and chronic). In addition, apathy has significant functional consequences on the patient's quality of life, as well as on his or her global functioning. Indeed, apathy impacts on his or her social and professional life. Patients with schizophrenia have a loss of autonomy, less employment and social withdrawal. Consequently, interest in its drug or treatment it is obvious. However, drug and non-drug treatments are not specific to apathy and therefore little effective on this syndrome. Implications to stimulate future research are presented.

[Blood-injection-injury phobia: Physochophysiological and therapeutical specificities]. / La phobie du sang-injection-accident : spécificités psychophysiologiques et thérapeutiques.

INTRODUCTION: Seventy-five percent of patients with blood-injection-injury phobia (BII-phobia) report a history of fainting in response to phobic stimuli. This specificity may lead to medical conditions remaining undiagnosed and untreated, incurring considerable cost for the individual and society. The psychophysiology of BII-phobia remains poorly understood and the literature on effective treatments has been fairly sparse. Aims of the systematic review: to synthesize the psychophysiology of BII-phobia and to propose a systematic review of the literature on effectiveness of different treatments evaluated in this indication. RESULTS: Firstly, the most distinct feature of the psychophysiology of BII-phobia is its culmination in a vasovagal syncope, which has been described as biphasic. The initial phase involves a sympathetic activation as is typically expected from fear responses of the fight-flight type. The second phase is characterized by a parasympathetic activation leading to fainting, which is associated with disgust. Subjects with syncope related to BII-phobia have an underlying autonomic dysregulation predisposing them to neurally mediated syncope, even in the absence of any blood or injury stimulus. Many studies report that BII-phobic individuals have a higher level of disgust sensitivity than individuals without any phobia. Secondly, behavioral psychotherapy techniques such as exposure only, applied relaxation, applied tension, and tension only, have demonstrated efficacy with no significant difference between all these techniques. The disgust induction has not improved effectiveness of exposure. CONCLUSION: We have explained the psychophysiology of BII-phobia, the understanding of which is required to study and validate specific techniques, in order to improve the prognosis of this disorder, which is a public health issue.

[Charisma and leadership: new challenges for psychiatry]. / Charisme et leadership: de nouveaux défis pour la psychiatrie.

INTRODUCTION: New challenges arise in medicine, particularly in psychiatry. In the near future, psychiatrists' role may evolve into management of mental health care teams (GPs, nurses, psychologists…) thus creating the need for charisma and leadership. Charisma is defined as « a quality that allows it's possessor to exercise influence, authority over a group ¼; leadership as « the function, the position of chief, and by extension, a dominant position ¼. AIM OF THE STUDY: To offer some reflections on charisma and leadership and the ways to develop them in three situations common in clinical practice: dual communication (between caregivers or with patients), oral communication (e.g., during a symposium) and managing a mental health care team. METHOD: Medline (1966-hits) and Web of Science (1975-hits) were explored according to the PRISMA criteria. The research paradigm was [(psychiatrist OR physician) AND mental health AND (leadership OR charisma)]. RESULTS: Two hundred and eighty articles were found, but only 34 corresponded to our subject and were included in the qualitative analysis. The leader must first ask himself/herself about his/her vision of the future, so as to share it with passion with his/her mental health team. Charisma and leadership are based on several values, among which we can mention: providing understandable, personalized care for the patient, in continuity and confidentiality; adapting care to the general population's request, maintaining one's own physical and mental health, submitting one's daily practice to peer review, engaging in continuous improvement of one's practices in response to new requirements, and recognizing that research and instruction are part of an M.D's professional obligations. The clinician will work on ways to develop his/her own charisma, through interactions with peers and team members, the care of his/her appearance (especially for first meetings) and workplace, and through positive reinforcement (some cognitive-behavioral techniques like assertiveness have been proposed to enhance the charisma, e.g., visualization and affirmation). Leadership does not depend on hierarchical position and administrative responsibilities: leaders should learn to manage and harmonize the different types of personalities within his/her team, paying special attention to passive-aggressive attitudes. We recall here some techniques to improve charisma during oral communication, such as making relationships with people by calling them by their names, making reference to things and people that the audience can identify with (like sport or cooking), using one's own style without trying to imitate someone else, focusing on one major idea, being brief and using anecdotes, using silences effectively and finally having good non-verbal communication. The conclusion should never be neglected, as an audience especially remembers the beginning and the end of a presentation. Although some features are common to all charismatic leaders (dominance, self-confidence, high energy level), a recent theory of leadership (called contingency theory) seeks to examine how different leadership styles can adapt to circumstances. This theory focuses more on the vision, passion, determination and courage of the leader and depends not only on their intrinsic qualities. No research has indeed shown individual characteristics that differentiate leaders from followers. However, doctors have not been prepared in their training to acquire leadership skills that they can use to adapt to the circumstances of their clinical practice. The most important qualities expected of a leader according to the current leadership theorists are: listening, communication, stress management, development of other's capacities, feedback, introspection and risk taking. Moreover, leadership involves positive reinforcement of the team while maintaining the feeling of individual autonomy, and being able to take an innovative decision alone with shared optimism. There is no need to have great management responsibilities in order to succeed in leadership. We reiterate the importance for a charismatic leader to smile, to be able to mock oneself and to regulate one's emotions. CONCLUSION: Charisma seems to be an essential dimension for effective leadership and team management. Beyond psychiatry, we believe these reflections to be useful for all branches of medicine.

[Toxoplasma gondii: a potential role in the genesis of psychiatric disorders]. / Toxoplasma gondii : un rôle potentiel dans la genèse de troubles psychiatriques. Une revue systématique de la littérature.

INTRODUCTION: Toxoplasma gondii is the most common protozoan parasite in developed nations. Up to 43% of the French population may be infected, depending on eating habits and exposure to cats, and almost one third of the world human's population may be infected. Two types of infection have been described: a congenital form and an acquired form. Although the medical profession treats these latent cases as asymptomatic and clinically unimportant, results of animal studies and recent studies of personality profiles, behavior, and psychomotor performance have led to reconsider this assumption. PRECLINICAL DATA: Among rats: parasite cysts are more abundant in amygdalar structures than those found in other regions of the brain. Infection does not influence locomotion, anxiety, hippocampal-dependent learning, fear conditioning (or its extinction) and neophobia in rats. Rats' natural predator is the cat, which is also T. gondii's reservoir. Naturally, rats have an aversion to cat urine, but the parasite suppresses this aversion in rats, thus influencing the infection cycle. Tachyzoites may invade different types of nervous cells, such as neurons, astrocytes and microglial cells in the brain, and Purkinje cells in cerebellum. Intracellular tachyzoites manipulate several signs for transduction mechanisms involved in apoptosis, antimicrobial effectors functions, and immune cell maturation. Dopamine levels are 14% higher in mice with chronic infections. These neurochemical changes may be factors contributing to mental and motor abnormalities that accompany or follow toxoplasmosis in rodents and possibly in humans. Moreover, the antipsychotic haloperidol and the mood stabilizer valproic acid most effectively inhibit Toxoplasma growth in vitro with synergistic activity. CLINICAL DATA: The effects of the parasite are not due to the manipulation in an evolutionary sense but merely due to neuropathological or neuroimmunological effects of the parasite's presence. Toxoplasmosis and schizophrenia: epidemiological studies point to a role for toxoplasmosis in schizophrenia's etiology, probably during pregnancy and early life, this association being congruent with studies in animal models indicating that animal exposures of the developing brain to infectious agents or immune modulating agents can be associated with behavioral changes that do not appear until the animal reaches full maturity. Psychiatric patients have increased rates of toxoplasmic antibodies, the differences between cases and controls being greatest in individuals who are assayed near the time of the onset of their symptoms. The increase of dopamine in the brain of infected subjects can represent the missing link between toxoplasmosis and schizophrenia. Toxoplasmosis and Obsessive Compulsive Disorder (OCD): the seropositivity rate for anti-T. gondii IgG antibodies among OCD patients is found to be significantly higher than the rate in healthy volunteers. Infection of basal ganglia may be implicated in the pathogenesis of OCD among Toxoplasma seropositive subjects. Toxoplasmosis and personality: infected men appear to be more dogmatic, less confident, more jealous, more cautious, less impulsive and more orderly than others. Conversely, infected women seem warmest, more conscientious, more insecure, more sanctimonious and more persistent than others. It is possible that differences in the level of testosterone may be responsible for the observed behavioral differences between Toxoplasma-infected and Toxoplasma-free subjects. CONCLUSION: In the future two major avenues for research seem essential. On one hand, prospective studies and research efforts must still be carried out to understand the mechanisms by which the parasite induces these psychiatric disorders. On the other hand, it has not yet been demonstrated that patients with positive toxoplasmic serology may better respond to haloperidol's or valproic acid's antiparasitic activity. These results may appear as a major issue in the drug's prescribing choices and explain variability in response to the treatment of patients with schizophrenia that is not explained by the genetic polymorphism.

[Evolution of the concept of apathy: the need for a multifactorial approach in schizophrenia]. / Évolution du concept d'apathie: nécessité d'une approche multifactorielle dans la schizophrénie.

BACKGROUND: Schizophrenia is a chronic and severe mental illness that affects over 1% of the population, characterized by multiple symptom dimensions. One of this class of symptoms, "negative symptoms", have received more attention over the last few years. Negative symptoms, including among others blunted affect, withdrawal or apathy, are particularly important for recovery and are associated with negative functional outcomes, such as inability to get an employment and conduct normal daily living activities. While positive symptoms are usually treated by antipsychotic drugs, negative symptoms are usually persistent, which indicates the need for better treatment. The aim of this article is to highlight recent scientific progress on apathy and to explore current multidimensional approaches of this concept in schizophrenia. Apathy is a symptom frequently encountered in schizophrenia and in many neurological disorders. Therefore, it can be regarded as a transnosographic symptom. LITERATURE FINDINGS: A long time considered as a loss of motivation (psychological concept hard to define), recent descriptive and etiological models have proposed to consider apathy as a multidimensional phenomenon. Marin et al., have proposed a model of apathy in reference to the motivation concept. Marin et al.'s apathy model is composed of three dimensions: firstly, cognitive dimension, secondly, sensory-motor dimension and thirdly, affective dimension. These authors propose to differentiate "apathy syndrome" from "apathy symptom". "Apathy syndrome" resulting from a lack of motivation whereas "apathy symptom" results from cognitive and/or emotional/affective disorders. In addition, Marin et al. propose that apathy syndrome corresponds to the "lack of motivation" not attributable to diminished level of consciousness, cognitive impairment or emotional distress. Following this proposal, Levy and Dubois propose to define apathy as a quantitative reduction of self-generated, voluntary and purposeful behaviors. It is therefore observable and can be quantified. Levy and Dubois have proposed an apathy model considering: firstly, apathy as a syndrome related to reduction in goal-directed behaviors; secondly, anatomically, apathy can be secondary to dysfunctions or lesions of the prefrontal cortex. Since the prefrontal cortex is functionally and anatomically heterogeneous, subtypes of apathy occur in diseases affecting the basal ganglia, because these diseases disrupt associative and limbic pathways from/to the prefrontal cortex; thirdly, from a pathophysiological point of view, apathy may be explained by the impact of lesions or dysfunctions of the basal ganglia, because these lesions or dysfunctions lead to a loss of temporal and spatial focalization, both of which result in a diminished extraction of the relevant signal within the frontal cortex, thereby inhibiting the capacity of the frontal cortex to select, initiate, maintain and shift programs of action.

3-year incidence and predictors of metabolic syndrome in schizophrenia in the national FACE-SZ cohort.

AIMS: Metabolic Syndrome (MetS) is a major health epidemic of Western countries and patients with schizophrenia is a particularly vulnerable population due to lifestyle, mental illness and treatment factors. However, we lack prospective data to guide prevention. The aim of our study is then to determine MetS incidence and predictors in schizophrenia. METHOD: Participants were recruited in 10 expert centers at a national level and followed-up for 3 years. MetS was defined according to the International Diabetes Federation criteria. Inverse probability weighting methods were used to correct for attrition bias. RESULTS: Among the 512 participants followed-up for 3 years, 77.9% had at least one metabolic disturbance. 27.5% were identified with MetS at baseline and excluded from the analyses. Among the rest of participants (N = 371, mean aged 31.2 (SD = 9.1) years, with mean illness duration of 10.0 (SD = 7.6) years and 273 (73.6%) men), MetS incidence was 20.8% at 3 years and raised to 23.6% in tobacco smokers, 29.4% in participants receiving antidepressant prescription at baseline and 42.0% for those with 2 disturbed metabolic disturbances at baseline. Our multivariate analyses confirmed tobacco smoking and antidepressant consumption as independent predictors of MetS onset (adjusted odds ratios (aOR) = 3.82 [1.27-11.45], p = 0.016, and aOR = 3.50 [1.26-9.70], p = 0.0158). Antidepressant prescription predicted more specifically increased lipid disturbances and paroxetine was associated with the highest risk of MetS onset. CONCLUSION: These results are an alarm call to prioritize MetS prevention and research in schizophrenia. We have listed interventions that should be actively promoted in clinical practice.

Video self-confrontation as a therapeutic tool in schizophrenia: A randomized parallel-arm single-blind trial.

BACKGROUND: Lack of insight is a barrier to treating psychosis. Preliminary studies have suggested that showing people videos of their psychotic behaviour may improve personal insight. This clinical trial aimed to assess the effect of video self-confrontation. METHODS: Inpatients between 18 and 65 years old with schizophrenia or schizoaffective disorder were filmed upon admission to two psychiatric hospitals while experiencing acute psychosis. After stabilization, individuals were randomized 1:1 to the "self-video" group where they watched their own video or to the "no video" control group. The primary outcome was the Scale to assess Unawareness of Mental Disorder (SUMD) at 48 h by a blinded assessor. Secondary objectives included psychotic and depressive symptoms, medication adherence and functioning using the Functional Remission of General Schizophrenia. Patients were followed up for four months. RESULTS: 60 participants were randomized and the level of insight did not differ between groups at 48 h (p = 0.98). There was no impact on SUMD subscores or the other insight questionnaires at any timepoint, nor on psychopathology or medication adherence. At one month, the level of functioning of those in the "self-video" group (n = 23) was higher (61.8 vs 53.5, p = 0.02), especially concerning "Treatment" and "Daily life". No adverse effects were reported. After video self-confrontation, people expressed more positive than negative emotions and were less lost to follow-up. CONCLUSION: Video self-confrontation did not change levels of insight, but may have a therapeutic impact nonetheless, by improving levels of self-care and adherence to care, indicating that this innovative therapeutic tool requires further study. TRIAL REGISTRATION NUMBER: NCT02664129.

Redefining peripheral inflammation signature in schizophrenia based on the real-world FACE-SZ cohort.

BACKGROUND: Peripheral inflammation is associated with impaired prognosis in schizophrenia (SZ). Highly sensitive C-reactive protein (hs-CRP) is the most used inflammatory biomarker in daily practice. However, no consensual cut-off has been determined to date to discriminate patients with peripheral inflammation from those without. AIMS: To determine if patients with peripheral inflammation between 1 and 3 mg/L had poorer outcomes compared to those with undetectable CRP (<1 mg/L). METHOD: Consecutive participants of the FACE-SZ cohort with a hs-CRP < 3 mg/L were included in 10 expert academic centers with a national geographical distribution between 2010 and 2018. Potential sources of inflammation, socio-demographics, illness characteristics, current illness severity, functioning and quality of life and were reported following the FACE-SZ standardized protocol. RESULTS: 580 patients were included, of whom 226 (39%) were identified with low-grade inflammation defined by a hs-CRP between 1 and 3 mg/L. Overweight and lack of dental care were identified as potential sources of inflammation. After adjustment for these factors, patients with inflammation had more severe psychotic, depressive and aggressive symptomatology and impaired functioning compared to the patients with undetectable hs-CRP. No association with tobacco smoking or physical activity level has been found. CONCLUSIONS: Patients with schizophrenia with hs-CRP level between 1 and 3 mg/L should be considered at risk for inflammation-associated disorders. Lowering weight and increasing dental care may be useful strategies to limit the sources of peripheral inflammation. Hs-CRP > 1 mg/L is a reliable marker to detect peripheral inflammation in patients with schizophrenia.
