Schizophrenia spectrum disorders (SSD) are frequently associated with disturbances in both neurocognition and social cognition. The patoetiology of SSD derives from a complex interaction between genes and environment. Exposome score for schizophrenia (ES-SCZ) is a cumulative environmental exposure score for schizophrenia which have shown potential utility in risk stratification and outcome prediction.

To investigate whether ES-SCZ is associated with cognition in patients with SSD, unaffected siblings, and healthy controls.

The present cross-sectional study included 1141 patients with SSD, 1332 unaffected siblings, and 1495 healthy controls, recruited in the Netherlands, Spain, Serbia, and Turkey. The Wechsler Adult Intelligence Scale (WAIS) was used to evaluate neurocognition, while the Degraded Facial Emotion Recognition (DFAR) task was used to assess social cognition. ES-SCZ was calculated based on our previously validated method. Associations between ES-SCZ and cognitive domains were analyzed by applying regression models in each group (patients, siblings, and controls), adjusted by age, sex, and country.

According to our preliminary analyses, no significant associations were found between ES-SCZ and cognition in patients with SSD. ES-SCZ was negatively associated with WAIS in unaffected siblings (B=−0.40, p=0.03) and controls (B=-0.63, p=0.004) and positively associated with DFAR in siblings (B=0.83, p=0.004). No significant association between ES-SCZ and DFAR was found in healthy controls.

Our findings show that neurocognition and social cognition are oppositely associated with ES-SCZ. Longitudinal studies may clarify whether there is a cause-effect relationship between ES-SCZ and cognition. Further research should investigate whether ES-SCZ interacts with molecular genetic risk for schizophrenia to improve clinical chcracterization and outcome prediction in people with SSD.

People with mental disorders may present impairments in cognitive and metacognitive functions. Self-reflection is the ability to reflect on oneself (specifically on one’s behavior, emotions, and thoughts) and insight is the awareness of one’s internal experience. Mindwandering (MW) is defined as the tendency to divert attention from current reality without a clearly defined intention. It can be spontaneous or deliberate. Several studies have investigated these alterations in patients with schizophrenia (SZ), while less is known for people with substance use disorder (SUD).

The aim of the present study was to explore self-reflection, insight and MW in a group of patients with SZ and SUD.

The Self-reflection and Insight Scale (SRIS) and the spontaneous (MW-S) and deliberate (MW-D) mindwandering scales were administered to 25 patients with SZ, 21 patients with SUD, and 21 healthy controls (HC). Linear regressions were performed to evaluate the associations between the variables under study.

Preliminary data showed that SZ and SUD patients presented lower SRIS and MW values than HC. Examining MW in detail, participants with SZ reported higher scores at than MW-D, while in people with SUD, MW-D scores were higher than MW-S scores. Linear regressions revealed that MW-D was negatively associated with self-reflection in SUD; moreover, insight scores were negatively associated with MW-S in SZ.

Our preliminary results confirm the importance of acting on the elements of metacognition in patients with mental disorders to improve the general outcome of the disease. A comprehensive therapeutic approach should include psychotherapeutic and social interventions aimed at increasing attention and introspection.

Autism spectrum disorder (ASD) is a heterogenous groups of neurodevelopmental conditions characterized by difficulties in social communication and the presence of restricted interests and repetitive behaviors. Autistic traits are distributed along a continuum in the general population and are negatively associated with social functioning also in non-autistic subjects. Several studies have evaluated the association between autistic traits and the quantity of social interaction; however, evidence on the relationship between autistic traits and quality of social interaction is still scarce.

To evaluate the association between autistic traits and the quality of social interactions in daily life in youths from the general population using the experience samplic method (ESM).

During a six-day experience sampling period, 349 twins and 248 of their siblings aged between 15 and 34 reported the quality of their everyday social interactions. Autistic traits were assesed using the Autism Spectrum Quotient (AQ). The association between autistic traits and quality of social interaction was tested in separate multilevel linear and logistic regression models.

When participants were alone, higher autistic traits were associated with a sense of being less safe (B=-0.02, p=0.02). When participants were in company, higher autistic traits were associated with a higher preference for being alone (B=0.02, p<0.001) and higher sense of being judged (B=0.03, p=0.001). Moreover, while in company, higher autistic traits were associated with a decreased pleasure of being in company (B=-0.03, p<0.001), a lower sense of being safe in company (B=-0.03, p<0.001), and a lower sense of belonging to a group (B=-0.02, p<0.001).

The preliminary results of the present study showed that autistic traits may influence the quality of social interactions in daily life. Future studies may clarify the mechanisms underlying this association. Assessing autistic traits in youth may help improve the outcome of psychosocial interventions of youths presenting difficulties in social interactions.

Exposome is all nongenetic exposures from the prenatal period to death. Exposome score for schizophrenia (ES-SCZ) is a cumulative measure of environmental liability for schizophrenia. Our previous studies showed that the ES-SCZ is associated with mental and physical health outcome.

The aim of the study is to investigate the association of the ES-SCZ with metabolic parameters in individuals with schizophrenia and healthy controls.

This study obtained 124 individuals with schizophrenia and 440 healthy controls from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions, Work Package 6 (Vulnerability and Severity) Turkey dataset. The ES-SCZ was calculated by summing log-odds weighted environmental exposures (childhood adversities, winter birth, hearing impairment and cannabis use). Linear regression analysis was used to investigate the association between ES-SCZ and metabolic parameters. After that analysis age and sex were added as covariates.

There was an association between ES-SCZ and diastolic blood pressure (B = -2.69 [95% CI -4.74; -.65], P-value = 0.010) in schizophrenia. ES-SCZ was associated with the fasting glucose level (B = -6.23 [95% CI -11.59; -.87], P-value = 0.023); high density lipid level (B = 1.77 [95% CI .27; 3.27], P-value = 0.021) in control and these results remained significant after adjusting for age and sex.

ES-SCZ was associated with important metabolic parameters. These findings show that ES-SCZ is not only related to increasing the risk for psychosis development but may also influence comorbidities. This result is important since it may increase our knowledge of ES-SCZ and contribute to the importance and framework of its clinical implementation.

Impairments in social and non-social cognition are common in psychosis and may be sparsely present even before the onset of the disorder. Genetic and environmental influences have been linked to cognitive dysfunctions, which, in turn, may significantly impact the real-world functioning of people with psychosis. The role of gender in determining the interplay between cognitive skills, risk factors, and outcomes has been relatively unexplored. Nevertheless, identifying putative gender differences in cognitive functions and their correlates may favor the identification of individualized prevention and treatment strategies.

Prior evidence suggests that men and women might be differentially susceptible to distinct types of childhood adversity (CA), but research on gender-specific associations between CA subtypes and psychiatric symptoms is limited.

To test the gender-specific associations of CA subtypes and psychiatric symptoms in the general population.

Data from 791 twins and siblings from the TwinssCan project were used. Psychopathology and CA exposure were assessed using the Symptom Checklist-90 Revised (SCL-90) and the Childhood Trauma Questionnaire (CTQ), respectively. The associations between the total CTQ scores and SCL-90 scores (i.e. total SCL-90, psychoticism, paranoid ideation, anxiety, depression, somatization, obsessive-compulsive, interpersonal sensitivity, hostility, and phobic anxiety) were tested in men and women separately. The associations between the five CA subtypes (i.e. physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect) and total SCL-90 were tested in a mutually adjusted model. As exploratory analyses, the associations between all CA subtypes and the nine SCL-90 subdomain scores were similarly tested. The regression coefficients between men and women were compared using Chow’s test. All models were adjusted for age and family structure.

Total CTQ was significantly associated with total SCL-90 in men (B = 0.013, SE = 0.003, P < .001) and women (B = 0.011, SE = 0.002, P < .001). The associations with the nine symptom domains were also significant in both genders (P < .001). No significant gender differences in the regression coefficients of total CTQ were detected. The analyses of CA subtypes showed a significant association between emotional abuse and total SCL-90 in women (B = 0.173, SE = 0.030, P < .001) and men (B = 0.080, SE = 0.035, P = .023), but the association was significantly stronger in women (ꭓ2(1) = 4.10, P = .043). The association of sexual abuse and total SCL-90 was only significant in women (B = 0.217, SE = 0.053, P < .001). The associations of emotional neglect (B = 0.061, SE = 0.027, P = .026) and physical neglect (B = 0.167, SE = 0.043, P < .001) with total SCL-90 were only significant in men. The explorative analyses of SCL-90 subdomains revealed significant associations of emotional abuse with all nine symptom domains and of sexual abuse with seven symptom domains in women. Significant associations of physical neglect with six symptom domains and of emotional neglect with depression were also detected in men. No other significant associations between CT subtypes and total SCL-90 or symptom domain scores were observed in men and women.

CA exposure was associated with diverse psychopathology similarly in both genders. However, women are more sensitive to abuse, but men are more sensitive to neglect. Gender-specific influences of CA subtypes on psychopathology should be considered in future studies.

The European Psychiatric Association (EPA) Summer School allows psychiatric trainees and early career psychiatrists (ECPs) from all over Europe to meet, network, and learn together. After the 2020 edition being cancelled due to COVID-19, the 10th edition in 2021 focused for the first time on research and was conducted remotely.

To provide an overview and feedback about the first Virtual EPA Research Summer School as a new way to encourage international networking during COVID-19.

The School was organized by the EPA Secretary for Education, and 4 Faculty members. It started with a “breaking the ice session” one week before and then a two-days meeting on 23-24 September 2021 using an online video-platform. This was preceded by all the 21 participants (from 18 different countries) recording a short 4-minute video presentation, which was uploaded and shared with other participants and Faculty.

Participants were divided on a voluntary basis into three working groups: 1) “Drug repurposing: overcoming challenges in pharmacoepidemiology” 2) “Psychopathological research in psychiatry”; 3) “How to conduct a cross-sectional survey?”. The Summer School program was composed of plenary sessions with lectures by the Faculty members, discussion sessions, and working groups time. At the end, each group presented a summary of the work done to the rest of the participants.

Although the remote format limits social interactions during the Summer School, overall participants’ high satisfaction and productivity indicate that not only online formats, but also the topic of research might be covered in future editions.

Autism spectrum disorder (ASD) is a group of life-long neurodevelopmental conditions characterized by impairments in social communication and by the presence of restricted interests or repetitive behaviors. Several genetic, biological, and psychosocial mechanisms seem to play a role in the etiopathogenesis of this complex condition. Preclinical models have shown a potential role of oxytocin (OT), a peptide involved in a complex range of behaviors, including those related to social interaction. Therefore, it has been hypothesized that OT levels may be decreased in autistic people.

To compare the levels of peripheral OT in autistic people vs neurotypical controls.

We performed a systematic literature search up to December 2020 according to PRISMA guidelines. Final inclusion was based on the following criteria: (1) Participants: individuals of any age diagnosed with ASD; (2) Controls: neurotypical subjects; (3) Outcome: OT levels, either in saliva, serum, or plasma; (4) Study design: case-control. Meta-analyses are ongoing.

We finally included 21 papers published between 1998 and 2020, of which one recruited adult participants. Fifteen studies measured OT levels in plasma, 4 in saliva, and 2 in serum. Preliminary meta-analyses on 10 studies showed that peripheral OT levels in autistic individuals are reduced compared to neurotypical controls, with sex differences.

Our preliminary findings show that peripheral OT might represent a potential biomarker for ASD. Future well-conducted case-control studies with a detailed phenotypical characterization of samples are needed to understand the role of OT deficits in specific subgroups.

The influence of personality on field of study choice is comparable to that of cognitive skills. Additionally, personality traits seem linked with academic motivation, and engagement. Choosing the most suitable career is also related to students’ personal well-being and work success.

To explore how personality traits are associated with the choice of university courses among Italian students.

A web-survey was spread on social networks between March and June 2020 through Google Forms. Eligibility criteria for inclusion were: 1) Being a university student between 18 and 35 years of age; 2) Attending a course in an Italian university; 3) Good comprehension of Italian language. On-line informed consent, socio-demographic, and career data were collected during the survey. Personality traits were assessed using the Big Five Inventory (BFI). We computed multinomial linear regressions to calculate potential associations between personality traits and university courses.

Lower Conscientiousness, higher Neuroticism, and higher Openness to experience are associated with the attendance of Humanities compared with students of Health faculties. Higher Neuroticism traits are associated with the attendance of a scientific course compared with Health faculties. High Conscientiousness is significantly associated with the attendance of Law-related courses compared with Health courses. Non significant differences were detected in the other domains according to the big five personality model.

Our results suggest interesting associations between personality traits and educational choices. Future research may investigate this relationship in high-school students to implement appropriate strategies for better addressing students’ educational needs and career outcomes.

Social cognition refers to a complex set of mental abilities that support the construction of adequate social competence and adaptation. Impairments in social cognition can be found in several psychiatric disorders, particularly in psychoses. Polygenic Risk Scores (PRSs) represent single metrics of molecular genetic risk and are a predictor of the genetic susceptibility to diseases, although they explain only a small part of the risk.

To explore the association between PRS for psychiatric disorders and social cognition.

We conducted a systematic search in PubMed and Scopus according to the PRISMA guidelines up to August 2021. We included papers evaluating PRS and social cognition with psychometric scales. Articles concerning single-nucleotide polymorphisms and biological measures of social cognition (e.g., neuroimaging, peripheral biomarkers) were excluded.

We initially retrieved 150 articles. After removing duplicates, we screened 133 titles and abstracts and preliminary selected 19 papers. Participants recruited in the papers of interest were either people with schizophrenia, ASD or ADHD, their family members or healthy subjects. Articles evaluated the association between different psychometrical measures of social cognition and PRS for schizophrenia, Autism Spectrum Disorder and ADHD.

Literature regarding the association between PRS for psychiatric disorders and social cognition is heterogeneous in terms of populations, genetic risk evaluation, and outcome tools. Given the critical role played by social cognition in the onset and progression of mental disorders and its association with real-world functioning, future research should try to disentangle the complex genetic basis of this domain.

People with autism spectrum disorder (ASD) frequently need support due to the elevated prevalence of psychiatric and medical comorbidities. The Covid-19 outbreak has severely affected the routinary functioning of healthcare services, thus causing severe consequences for autistic people and their caregivers, an already fragile population prone to mental health diseases.

1. To compare the levels of psychological well-being, insomnia, and family distress perceived by caregivers of autistic people to those perceived by caregivers of people with other types of disability. 2. To evaluate predictors of individual and family distress reported by caregivers of autistic individuals.

We collected data through a cross-sectional web-based observational study from April 19 to May 3, 2020. Socio-demographic information were collected, and psychopathological variables were assessed using the General Health Questionnaire-12, the Insomnia Severity Index, the Brief Resilient Coping Scale, and the Family Distress Index.

No significant differences emerged between the two groups of caregivers in terms of well-being, sleep quality, family distress, and level of resilience. The risk of individual distress during the pandemic was higher in people caring for younger autistic people. Lower levels of resilience predicted higher levels of individual distress among caregivers of autistic people.

Our study confirmed that caregivers’ mental health is worthy of attention and that people with disabilities may benefit for well-organized healthcare support networks (e.g. in-home services). The non-significant differences found between caregivers of ASD and non-ASD individuals may be related to the severe distress that Covid pandemic caused on the entire population.

Abnormalities of sleep patterns are common in people with psychiatric disorders and often represent a source of distress, worsening the outcome. However, little is knwon about the relationship between psychotic-like symptoms and sleep disorders in the general population.

1. Whether there is a relationship between sleep disorders and psychotic-like experiences in a sample of individuals belonging to the general population. 2. Which sleep disorders are more commonly associated with psychotic-like experiences.

A web survey was spread thorugh social networks. We administered the SLEEP-50 to investigate the presence of sleep disorders and the Community Assessment of Psychic Experience (CAPE) for psychotic-like symptoms. Moreover, socio-demographic characteristics of participants were collected.

The web-survey was completed by 824 participants. Six people refused to give consent and 95 were excluded because they declared to suffer from psychiatric disorder sor other medical conditions potentially infleuncing on sleep. Therefore, 729 subjects were included in the analysis. Pearson correlation coefficients showed strong correlations between the scale regarding SLEEP-50 “All sleep disorders” scale and CAPE Total and Depressive scales (r = 0.52, p < 0.001). A moderate correlation was found between “All sleep disorders” and CAPE Negative (r = 0.49) and Positive (r = 0.32) scales. Correlations with specific SLEEP-50 subscales were also found.

There seems to be a strong relationship between psychotic-like symptoms and sleep problems in the general population. Our findings might indicate that some sleep abnormalities may represent earlier symptoms of a psychiatric condition and need to be always monitored even in the non-psychiatric population.

People from the general population often tend to believe that psychiatric patients may be incurable, dangerous, and unpredictable. Stigma represents a critical issue which should be defeated. In spite of the interest of research, little is known about the relationship between personality traits and level of stigma toward people with mental illness.

To evaluate whether certain personality traits can influence the level of stigma towards mental illness in a population of university students.

A web-survey was spread on social networks between March and June 2020 through Google Forms. Eligibility criteria for inclusion were:1) Being 18 years of age or older; 2) Attending a degree course in an Italian University; 3) Provide informed consent. Socio-demographic characteristics of the participants were collected. Stigma was measured using the Attribution Questionnaire (AQ-27), personality traits were evaluated through the Big Five Inventory (BFI) and the Mental Health Knowledge Schedule (MAKS-i) investigated the knowledge about mental illness. Statistical analyses were performed using SPSS 24.0.

We computed a multiple linear regression to calculate potential predictors of stigma, adjusted on the basis of the knowledge of mental illness. Results showed that age and faculty class were not related to stigma. Agreeableness (A) and Openness to experience (O) were associated with less stigmatizing attitudes. Conversely, Neuroticism (N) and Conscientiousness (C) seemed to predict higher levels of stigma.

Our results suggest an interesting relationship between personality traits and stigmatizing attitudes, which deserves to be further studied. They also confirm the importance of implementing appropriate strategies against the stigma of mental illness.

A cumulative environmental exposure score for schizophrenia (exposome score for schizophrenia [ES-SCZ]) may provide potential utility for risk stratification and outcome prediction. Here, we investigated whether ES-SCZ was associated with functioning in patients with schizophrenia spectrum disorder, unaffected siblings, and healthy controls.

This cross-sectional sample consisted of 1,261 patients, 1,282 unaffected siblings, and 1,525 healthy controls. The Global Assessment of Functioning (GAF) scale was used to assess functioning. ES-SCZ was calculated based on our previously validated method. The association between ES-SCZ and the GAF dimensions (symptom and disability) was analyzed by applying regression models in each group (patients, siblings, and controls). Additional models included polygenic risk score for schizophrenia (PRS-SCZ) as a covariate.

ES-SCZ was associated with the GAF dimensions in patients (symptom: B = −1.53, p-value = 0.001; disability: B = −1.44, p-value = 0.001), siblings (symptom: B = −3.07, p-value < 0.001; disability: B = −2.52, p-value < 0.001), and healthy controls (symptom: B = −1.50, p-value < 0.001; disability: B = −1.31, p-value < 0.001). The results remained the same after adjusting for PRS-SCZ. The degree of associations of ES-SCZ with both symptom and disability dimensions were higher in unaffected siblings than in patients and controls. By analyzing an independent dataset (the Genetic Risk and Outcome of Psychosis study), we replicated the results observed in the patient group.

Our findings suggest that ES-SCZ shows promise for enhancing risk prediction and stratification in research practice. From a clinical perspective, ES-SCZ may aid in efforts of clinical characterization, operationalizing transdiagnostic clinical staging models, and personalizing clinical management.

Executive and mnemonic impairments have been well documented in the high-risk states for development of psychosis and have been pinpointed as a possible core neuropsychological dysfunction. However, their neurofunctional correlates are still not clear.

fMRI was used in 17 patients at risk for developing psychosis (ARMS, “at risk mental state”), 10 patients with a first episode of psychosis (FEP) and 15 age-matched healthy comparison subjects to examine neural responses to increasing difficulty of mnemonic engagement in an object–location paired associate memory task. Groups were matched in terms of age, IQ, gender, and psychopathology ratings. Accuracy and reaction time were recorded during the scan.

As the mnemonic load increased, response latency increased and response accuracy decreased in an approximately linear fashion. No main effect for group was observed. However, a trend towards decreased accuracy in FEP subjects, as compared with controls, was evident. As the task difficulty increased, increased brain activity was observed in the medial frontal cortex and in the medial posterior parietal cortex. Between-groups differences in activation were observed in a cluster spanning the MFG, SFG and SMA and in the right precuneus. However, these neurofunctional abnormalities were more evident in the most demanding level of the task than in the easy level, with the ARMS groups showing less activation than controls and higher activation than FEP.

Abnormal neural activity in medial frontal cortex and posterior parietal cortex during paired associate learning task may represent a neurofunctional substrates of vulnerability to psychosis.

People with ‘prodromal’ symptoms have a very high risk of developing psychosis. We used functional MRI to examine the neurocognitive basis of this vulnerability.

Cross-sectional comparison of subjects with an ARMS (n=17), first episode schizophreniform psychosis (n=10) and healthy volunteers (n=15). Subjects were studied using functional MRI while they performed an overt verbal fluency task, a random movement generation paradigm and an N-Back working memory task.

During an N-Back task the ARMS group engaged inferior frontal and posterior parietal cortex less than controls but more than the first episode group. During a motor generation task, the ARMS group showed less activation in the left inferior parietal cortex than controls, but greater activation than the first episode group. During verbal fluency using ‘Easy’ letters, the ARMS group demonstrated intermediate activation in the left inferior frontal cortex, with first episode groups showing least, and controls most, activation. When processing ‘Hard’ letters, differential activation was evident in two left inferior frontal regions. In its dorsolateral portion, the ARMS group showed less activation than controls but more than the first episode group, while in the opercular part of the left inferior frontal gyrus / anterior insula activation was greatest in the first episode group, weakest in controls and intermediate in the ARMS group.

The ARMS is associated with abnormalities of regional brain function that are qualitatively similar to those in patients who have just developed psychosis but less severe.

Basic Self disturbances (BSD), including changes of the 'pre-reflexive' sense of self and the loss first-person perspective, are characteristic of the schizophrenic spectrum disorders and highly prevalent in subjects at 'ultra high risk' for psychosis (UHR). The current literature indicates that cortical midline structures (CMS) may be implicated in the neurobiological substrates of the 'basic self' in healthy controls.

Neuroanatomical investigation of BSD in a UHR sample

To test the hypotheses :(i) UHR subjects have higher 'Examination of Anomalous Self Experience, EASE' scores as compared to controls, (ii) UHR subjects have neuroanatomical alterations as compared to controls in CMS, (iii) within UHR subjects, EASE scores are directly related to structural CMS alterations.

32 HR subjects (27 antipsychotics-naïve) and 17 healthy controls (HC) were assessed with the 57-items semi-structured EASE interview. Voxel-Based Morphometry (VBM) was conducted in the same subjects, with a-priori Region of Interests (ROIs) defined in the CMS (anterior/posterior cingulate and medial-prefrontal cortex).

Despite high variability in the HR group, the overall EASE score was higher (t-test >0.01, Cohen's d =2.91) in HR (mean=30.15, SD=16.46) as compared to HC group (mean=1.79, SD=2.83). UHR subjects had gray matter reduction in CMS as compared to HC (p>0.05 FWE-corrected). Across the whole sample, lower gray matter volume in the anterior cingulate was correlated with higher EASE scores (p>0.05).

This study provides preliminary evidence that gray matter reductions in the CMS are correlated with BSD in UHR people.

Several psychotropic medications (i.e. antipsychotics, antidepressant) have been recently associated with QTc prolongation. Despite literature data report only mild prolongation of QTc following the use of antidepressants or typical antipsychotics, post-marketing studies have clearly evidenced an increased risk of QTc prolongation and potentially lethal arrhythmias (i.e. torsade de pointes) in psychiatric patients.

We aimed to evaluate the prevalence of prolonged QTc and to identify potential predictors influencing QTc in a psychiatric inpatient population.

Medical records of 200 patients admitted to our psychiatric ward between 2007 and 2012 were retrospectively reviewed.

Prevalence of prolonged QTc at admission was very low (0.1%). No significant differences in QTc interval were observed between patients taking or not antipsychotics (P = 0.66), mood stabilizers (P = 0.36), or antidepressants (P = 0.07). A statistically significant difference was observed between patients on depot formulation and patients who were taking oral antipsychotic (P = 0.02). However, the pharmaceutical class of the medications appeared not significant.

We observed a very low rate of QTc prolongation in psychiatric inpatients at admission. Surprisingly we did not find a significant effect of specific medications; however, in our sample intramuscular formulation was associated with lower QTc interval.

The authors have not supplied their declaration of competing interest.

Psychiatric population is characterized by a higher prevalence of cardiovascular events compared to general population. This difference might be due, in part, to the metabolic adverse effects of psychotropic agents, and, in part, to common risk factors such as smoking, sedentary lifestyle and unhealthy diet. Another potential risk factor is represented by the presence of metabolic syndrome (MetS).

We aimed to evaluate the prevalence of MetS and to identify the baseline predictors for the longitudinal development of MetS in a sample of Italian psychiatric inpatients.

Medical records of 343 patients admitted to our psychiatric ward between 2007 and 2012 were retrospectively reviewed.

Prevalence of MetS was 21.5%. MetS appeared directly associated with age and number of medication assumed. ROC curves showed HDL as the best predictor of metabolic syndrome in our sample.

Our results confirm previous data on the association between metabolic syndrome and exposure to complex polytherapy. Additionally, our findings support the notion of psychiatric patients as an at-risk group for metabolic abnormalities, which should be carefully monitored.

Co-occurrence of common mental disorders (CMD) with psychotic experiences is well-known. There is little research on the public mental health relevance of concurrent psychotic experiences for service use, suicidality, and poor physical health. We aim to: (1) describe the distribution of psychotic experiences co-occurring with a range of non-psychotic psychiatric disorders [CMD, depressive episode, anxiety disorder, probable post-traumatic stress disorder (PTSD), and personality dysfunction], and (2) examine associations of concurrent psychotic experiences with secondary mental healthcare use, psychological treatment use for CMD, lifetime suicide attempts, and poor self-rated health.

We linked a prospective cross-sectional community health survey with a mental healthcare provider database. For each non-psychotic psychiatric disorder, patients with concurrent psychotic experiences were compared to those without psychotic experiences on use of secondary mental healthcare, psychological treatment for CMD, suicide attempt, physical functioning, and a composite multimorbidity score, using logistic regression and Cox regressions.

In all disorders except for anxiety disorder, concurrent psychotic experiences were accompanied by a greater odds of all outcomes (odds ratios) for a unit change in composite multimorbidity score ranged between 2.21 [95% confidence interval (CI) 1.49–3.27] and 3.46 (95% CI 1.52–7.85). Hazard ratios for secondary mental health service use for non-psychotic disorders with concurrent psychotic experiences, ranged from 0.53 (95% CI 0.15–1.86) for anxiety disorders with psychotic experiences to 4.99 (95% CI 1.22–20.44) among those with PTSD with psychotic experiences.

Co-occurring psychotic experiences indicate greater public mental health burden, suggesting psychotic experiences could be a marker for future preventive strategies improving public mental health.
