RESUMO
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.

Until now, most studies investigating the relationship between event segmentation and memory have used videos filmed from a third-person perspective, although people experience their lives from a first-person perspective. The present study aimed to determine whether visual perspective impacts events segmentation and further recall. Fifty-seven participants were recruited and assigned to either first- (1PP) or third-person perspective (3PP) condition, before segmenting videos of daily life activities. Our results showed that the although the number of event boundaries was higher in the 3PP condition than in the 1PP, no differences were observed for event segmentation qualitative abilities and organization. Memory of temporal order was better for events encoded in the 3PP than in the 1PP, while memory content was similar in both conditions. Higher event segmentation rates were correlated with a better recall of small actions and temporal order.

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.

For more than a century, prehistoric research has focused on cave sites and rock shelters, mostly because of good preservation of organic remains associated with stratified anthropogenic layers. Manot Cave in the Western Galilee, Israel offers the possibility of studying prehistoric assemblages in pristine condition because of the collapse of the cave entrance some 30 thousand years ago. Nine years of excavations have uncovered an Early Upper Paleolithic archaeological sequence. Area C, situated at the bottom of the talus, was exposed to fast and slow depositional and postdepositional processes affecting sediment accumulation. The central part of area C was selected for this study, as it was least disturbed. Following a technotypological analysis, and taking postdepositional processes into consideration, the assemblages were defined and assigned to the Levantine Aurignacian, and Ahmarian traditions. The two archaeological horizons are separated by a mixed horizon within which indicative artifacts of both traditions alternately appear. The Ahmarian assemblage, dated to 46-42 ka cal BP, fits within the northern Mediterranean Ahmarian sites, which technotypologically differs from and is currently dated earlier than the southern desert region Ahmarian sites. The main technotypological characteristics of the assemblage from the Levantine Aurignacian Horizon, dated to 38-34 ka cal BP, are comparable to those from Manot Cave area E layers V-VI, and Ksâr 'Akil levels VII-VIII. Yet, several technotypological elements seem more compatible with the unnamed assemblage from Ksâr 'Akil levels XI-XIII and possibly layer IX from area E.

The psychological effects of isolation have already been described in the literature (polar expeditions, submarines, prison). Nevertheless, the scale of confinement implemented during the COVID-19 pandemic is unprecedented. In addition to reviewing the published studies, we need to anticipate the psychological problems that could arise during or at a distance from confinement. We have gone beyond the COVID-19 literature in order to examine the implications of the known consequences of confinement, like boredom, social isolation, stress, or sleep deprivation. Anxiety, post-traumatic stress disorder, depression, suicidal or addictive behaviours, domestic violence are described effects of confinement, but the mechanisms of emergence of these disorders and their interrelationships remain to be studied. For example, what are the mechanisms of emergence of post-traumatic stress disorders in the context of confinement? We also remind the reader of points of vigilance to be kept in mind with regard to eating disorders and hallucinations. Hallucinations are curiously ignored in the literature on confinement, whereas a vast literature links social isolation and hallucinations. Due to the broad psychopathological consequences, we have to look for these various symptoms to manage them. We quickly summarize the diagnostic and therapeutic approaches already in place, such as telemedicine, which is undergoing rapid development during the COVID-19 crisis.

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.

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.

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.

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.

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.

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.

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.

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.

OBJECTIVES: Disorders of self in schizophrenia have been considered as the core feature of the illness since its early clinical description. However, until recently, the understanding of these disorders referred mostly to philosophical considerations. The aim of this work is to examine how the various aspects of autobiographical memory deficits may be considered as possible cognitive mechanisms accounting for self-disorders in patients. METHODS: We performed a theoretical review of the literature on autobiographical memory studies in schizophrenia. Our approach of cognitive psychopathology was grounded in the model of the Self-Memory System put forward by Conway (2005), which posits reciprocal relationships between autobiographical memory and the self. This model stresses the distinction between the working-self and the autobiographical memory knowledge base. The latter contains all autobiographical information stored in our life and is organized according to the specificity of this information. The role of the working-self is to maintain the coherence of the self and to control the access to autobiographical memories and corresponding memory details. The working-self supports an experiential or phenomenological dimension of the self, especially when a highly detailed autobiographical memory is retrieved, and a past event is re-experienced by the rememberer. The working-self also entails a conceptual part, the conceptual self, which contains self-knowledge and self-images. RESULTS: Our review showed that autobiographical memories of patients with schizophrenia are less specific and contain fewer phenomenological details than those of healthy participants. Patients also have difficulty assessing the subjective temporal distance of past events, and their ability to re-experience unique past personal events is affected as shown by a reduced conscious recollection and a smaller frequency of Field visual perspective during recall of autobiographical memories. This global alteration of all phenomenological characteristics of autobiographical memories strongly suggests an alteration of the phenomenological dimension of the self in schizophrenia. Since some of these alterations are also found in patients when they plan for future personal events, the ability to mentally travel in time is reduced in patients and reflects an impaired sense of self across time. The literature also shows that self-images are more passive, less coherent and less stable in time in patients compared to healthy participants. These results point to an alteration of the conceptual dimension of the self in schizophrenia. This may be partly explained by a weaker connection between the self and autobiographical memory and by other alterations of autobiographical memories closely linked to the self. In fact, the reminiscence bump is disorganized in patients and comprises poorly detailed memories. Memories grounding self-images are less organized and weakly connected to self-images. Finally, patients have an impaired ability to give a meaning to or to draw lessons from self-defining memories of their life. CONCLUSION: Based on these results, we discuss current and future therapeutic interventions including both cognitive remediation methods and cognitive psychotherapy applied to autobiographical memory. These methods appear relevant to help patients improve both the sense of self associatied with their autobiographical memory retrieval and the coherence and stability of the self.

BACKGROUND: Disorders of the self, such as a reduced sense of personal continuity in time, are a core symptom of schizophrenia, but one that is still poorly understood. In the present study, we investigated two complementary aspects of self-continuity, namely phenomenological and narrative continuity, in 27 patients with schizophrenia, and compared them with 27 control participants. METHODS: Participants were asked to identify important past events and to narrate a story from their life that included these events. They were also asked to imagine important events that might happen in their personal future and to build a narrative of their future life. The vividness of these important life events and the proportion of self-event connections in the narratives were used as a measure of phenomenological and narrative continuity, respectively. RESULTS: Our study showed patients with schizophrenia experienced less vivid representations of personally significant events (p = .02) for both temporal directions (past and future) (p < .001). In addition, their ability to make explicit connections between personal events and self-attributes in life narratives was also impaired (p = .03), but only in the case of past narratives (p < .001). CONCLUSIONS: These results shed new light on the cognitive mechanisms underlying self-disorders in schizophrenia. The clinical and therapeutic implications of these findings are discussed.

OBJECTIVE: Life narratives of patients with schizophrenia are characterized by impaired coherence so that the listener has often difficulties to grasp the life trajectory of the patients. In order to better understand what causes this reduced temporal coherence, we investigated the temporal structure of patients' life narratives through different temporal narrative elements (elaboration of beginnings and endings, local temporal indicators and temporal deviations from a linear order), across two complementary studies. METHODS: Life narratives were collected by means of two different methods; a free recall in study 1 and a more structured protocol, aiming at reducing the cognitive task demands in study 2. All narratives from the two studies were analyzed using the same validated method. RESULTS: Both studies showed that global temporal coherence is significantly reduced in patients with schizophrenia (ps.02). This is mainly due to their stronger tendency to temporally deviate from a linear temporal order without marking the deviation as such. We also observed significant correlations in the patient groups between global temporal coherence and executive dysfunction (p=.008) or their higher tendency to temporally deviate from a linear temporal order in their life narratives (p<.001). CONCLUSIONS: These results shed light on narrative correlates of temporal narrative incoherence in schizophrenia and highlight the central role of executive dysfunction in this incoherence.

Background: The objective of this study was to develop a conceptual framework to define a domain map describing the experience of patients with severe mental illnesses (SMIs) on the quality of mental health care. Methods: This study used an exploratory qualitative approach to examine the subjective experience of adult patients (18-65 years old) with SMIs, including schizophrenia (SZ), bipolar disorder (BD) and major depressive disorder (MDD). Participants were selected using a purposeful sampling method. Semistructured interviews were conducted with 37 psychiatric inpatients and outpatients recruited from the largest public hospital in southeastern France. Transcripts were subjected to an inductive analysis by using two complementary approaches (thematic analysis and computerized text analysis) to identify themes and subthemes. Results: Our analysis generated a conceptual model composed of 7 main themes, ranked from most important to least important as follows: interpersonal relationships, care environment, drug therapy, access and care coordination, respect and dignity, information and psychological care. The interpersonal relationships theme was divided into 3 subthemes: patient-staff relationships, relations with other patients and involvement of family and friends. All themes were spontaneously raised by respondents. Conclusion: This work provides a conceptual framework that will inform the subsequent development of a patient-reported experience measure to monitor and improve the performance of the mental health care system in France. The findings showed that patients with SMIs place an emphasis on the interpersonal component, which is one of the important predictors of therapeutic alliance. Trial registration: NCT02491866.
RESUMO
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.

BACKGROUND: Sleep disorders associated factors are under explored in schizophrenia while the literature suggests high and heterogeneous frequency. AIMS: The objective of the present study was to determine the prevalence and risk factors of sleep disorders in the real-world FACE-SZ national cohort. METHOD: Stabilized schizophrenic outpatients were recruited in 10 expert centers for schizophrenia. Sleep quality was explored with the Pittsburgh Sleep Quality Index (PSQI) and sleep disorders was defined by a PSQI score > 5. Psychosis severity was measured with the Positive and Negative Syndrome Scale, current major depressive episode with the Calgary Depression Scale for Schizophrenia, verbal aggressiveness with the Buss-Perry Aggression Questionnaire, adherence to treatment with the Medication Adherence Rating Scale, akathisia with the Barnes Akathisia Scale. Current somatic comorbidities and body mass index were reported. Variables with P values <0.20 in univariate analysis were included in a multivariate regression model. RESULTS: Of the 562 included patients, 327 subjects (58.2%, IC95% [54.1% - 62.3%]) reported having sleep disorders. After adjustment, sleep disorders were significantly associated with migraine (adjusted odds ratio aOR = 2.23, p = 0.041), major depressive disorder (aOR 1.79, p = 0.030), poor adherence to treatment (aOR = 0.87, p = 0.006), akathisia (aOR = 1.29, p = 0.042) and verbal aggressiveness (aOR = 1.09, p = 0.002). CONCLUSIONS: More than one on two stabilized real-life outpatients with schizophrenia have been identified with sleep disorders. Combined with the literature data, we have yielded expert recommendations for the treatment and prevention of sleep disorders including treating undiagnosed comorbid depression and migraine and managing antipsychotic treatment to improve adherence and akathisia.

INTRODUCTION: Psychotic symptoms are not readily recognized in multiple sclerosis, especially at the beginning of the disease. METHODS: We report the cases of four patients who developed psychotic symptoms that led to the diagnosis of multiple sclerosis. We describe the psychiatric and neurological features, MRI findings, clinical outcome and treatment. RESULTS: Two patients developed persecutory delusions, one presented a manic episode and the fourth melancholia with catatonia. Mean age was 39 years (range 20-49 years). Two patients had a personal history, but none a familial history of psychiatric disease. Examination of the cerebrospinal fluid revealed an oligoclonal pattern in all patients. All patients fulfilled Barkhof's MRI criteria. Three have had brain MRI with injection during psychotic symptoms. In these three cases, a frontal lesion appeared. The patient with catatonia also had a new lesion in the cerebellum and in the brainstem. All patients needed a "psychiatric" treatment, including antipsychotics. The psychiatric event lasted three months for two patients and the two others experienced relapse. CONCLUSION: Acute psychiatric symptom may reveal multiple sclerosis at the beginning of the disease. Frontal lobe localization is suggested. We propose that a psychotic event may correspond to a multiple sclerosis event.
