Abstract
Background Cannabis is the most widely used illicit substance. Various countries have legalized cannabis for recreational use. Evidence on the health effects of cannabis regulation remains unclear and is mainly based on observational studies. To date, there is no randomized controlled study evaluating the impact of cannabis regulation for recreational use compared to the illicit market on relevant health indicators. The present study ("Weed Care") is the first to evaluate the impact of regulated cannabis access in pharmacies versus a waiting list control group representing the illicit market on problematic cannabis use as well as on mental and physical health. Methods The study is divided into two parts-a randomized controlled study of 6 months followed by an observational study of 2 years. Participants (N = 374) are randomly assigned to either the experimental group with access to legal cannabis in pharmacies or to the waiting list control group representing the current legal framework in Switzerland, namely the illicit market. After 6 months, all participants will have access to legal cannabis for the following 2 years (observational study). The primary outcome is problematic cannabis use as measured with the Cannabis Use Disorders Identification Test-Revised (CUDIT-R). Secondary outcomes are cannabis use patterns, mental disorders (e.g., depression, anxiety, and psychosis) and physical health (e.g., respiratory symptoms). Primary and secondary outcomes will be assessed online every 6 months. The study is approved by the responsible ethics committee as well as by the Swiss Federal Office of Public Health. Discussion Findings from this study may provide a scientific basis for future discussions about addiction medicine and cannabis policy in Switzerland.

Primary Psychosis: Risk and Protective Factors and Early Detection of the Onset. Diagnostics (Basel) 2021; 11:diagnostics11112146.

Abstract
Primary psychosis, which includes schizophrenia and other psychoses not caused by other psychic or physical conditions, has a strong impact worldwide in terms of disability, suffering and costs. Consequently, improvement of strategies to reduce the incidence and to improve the prognosis of this disorder is a current need. The purpose of this work is to review the current scientific literature on the main risk and protective factors of primary psychosis and to examine the main models of prevention, especially those related to the early detection of the onset. The conditions more strongly associated with primary psychosis are socio-demographic and economic factors such as male gender, birth in winter, ethnic minority, immigrant status, and difficult socio-economic conditions while the best-established preventive factors are elevated socio-economic status and an economic well-being. Risk and protective factors may be the targets for primordial, primary, and secondary preventive strategies. Acting on modifiable factors may reduce the incidence of the disorder or postpone its onset, while an early detection of the new cases enables a prompt treatment and a consequential better prognosis. According to this evidence, the study of the determinants of primary psychosis has a pivotal role in designing and promoting preventive policies aimed at reducing the burden of disability and suffering of the disorder.

Abstract
In this report, we present a case of a 16,9-year-old patient with multiple substance use disorder (cannabis, MDMA, cocaine, ecstacy), severe depression, social phobia and narcissistic personality disorder.We administered Cannabidiol (CBD) capsules in different dosages (starting dosage 100 mg up to 600 mg over 8 weeks) after unsuccessful treatment with antidepressants.CBD was a safe and well tolerated medication for this patient. Upon treatment with CBD and cessation of the antidepressant medication, the patient improved regarding depressive as well as anxiety symptoms including simple phobias and symptoms of paranoia and dissociation. Furthermore, the patient quit abusing illegal drugs including THC without showing withdrawal symptoms. This is the first report of CBD medication in a patient with multiple substance use disorder with a positive outcome.Until today it is not clear if CBD holds promise as a therapeutic option in substance use disorder as RCTs are lacking, but in this single case the substance seems to work in various domains.

Abstract
Saccadic eye movements are well-described markers of cerebral function and have been widely studied in schizophrenia spectrum populations. However, less is known about saccades in individuals clinically at risk for schizophrenia. Therefore, we studied individuals in an at-risk mental state (ARMS) (N = 160), patients in their first episode of schizophrenia (N = 32) and healthy controls (N = 75). N = 88 ARMS participants showed an early at-risk mental state (E-ARMS), defined by cognitive-perceptive basic symptoms (COPER) or a combination of risk and loss of function, whereas N = 72 were in a late at-risk mental state (L-ARMS), defined by attenuated psychotic symptoms or brief limited intermittent psychotic symptoms. We examined prosaccades, reflecting overt attentional shifts, and antisaccades, measuring inhibitory control, as well as their relationship as an indicator of the interplay of bottom-up and top-down influences. L-ARMS but not E-ARMS participants had increased antisaccade latencies compared to controls. First-episode patients had higher antisaccade error rates compared to E-ARMS participants and controls, and increased latencies compared to all other groups. Prosaccade latencies did not differ between groups. We observed the expected negative correlation between prosaccade latency and antisaccade error rate, indicating that individuals with shorter prosaccade latencies made more antisaccade errors. The magnitude of the association did not differ between groups. No saccadic measure predicted conversion to psychosis within 2 years. These findings confirm the existence of antisaccade impairments in patients with schizophrenia and provide evidence that volitional response generation in the antisaccade task may be affected even before onset of clinically overt psychosis.

Abstract
BACKGROUND Vulnerability-stress models postulate that social stress triggers psychotic episodes in vulnerable individuals. However, experimental evidence for the proposed causal pathway is scarce and the translating mechanisms are insufficiently understood. The study assessed the impact of social exclusion on paranoid beliefs in a quasi-experimental design and investigated the role of emotion regulation (ER) as a vulnerability indicator and emotional responses as a putative translating mechanism. METHODS Participants fulfilling criteria for clinical high risk of psychosis (CHR, n = 25), controls with anxiety disorders (AC, n = 40), and healthy controls (HC, n = 40) were assessed for dysfunctional (eg, rumination, catastrophizing, blaming) and functional ER-strategies (eg, reappraising, accepting, refocusing). They were then exposed to social exclusion during a virtual ball game (Cyberball) and assessed for changes in self-reported emotions and paranoid beliefs. RESULTS The CHR sample showed a significantly stronger increase in paranoid beliefs from before to after the social exclusion than both control groups. This was accounted for by lower levels of functional and higher levels of dysfunctional ER (compared to HC) and by a stronger increase in self-reported negative emotion in the CHR group (compared to AC and HC). CONCLUSIONS The results confirm the role of negative emotion on the pathway from social stressors to psychotic symptoms and indicate that both the use of dysfunctional ER strategies and difficulties in employing functional strategies add to explaining why people at risk of psychosis respond to a social stressor with increased paranoia.

Abstract
AIM Functional disability and social consequences frequently occur at the prodromal stage of schizophrenia. Efforts to recognize an increasing risk of psychosis onset have thus become a topical issue worldwide. This is to introduce the English version of the ERIraos early-recognition inventory. METHODS The ERIraos, developed in a systematic, empirical approach from the Instrument for the Retrospective Assessment of the Onset of Schizophrenia, incorporates basic symptoms from the Cologne Early Recognition Study. The research version also includes as further predictive items so-called brief limited intermittent psychotic symptoms and attenuated psychotic symptoms from the Comprehensive Assessment of At-Risk Mental States instrument. RESULTS The ERIraos with its 15-item screening Checklist and 50-item Symptom List permits early recognition of psychosis risk in three steps of decreasing sensitivity and increasing specificity. Step 1 relies on patients' self-perception of symptoms, which prompt them to contact a primary health service. There, in Step 2, at-risk individuals are identified using the Checklist, characterized by a low-risk threshold, and referred to further examination using the Symptom List (Step 3). Information on symptom accumulation and increasing symptom severity enhances the instrument's predictive power. In a validation test, psychotic transitions increased linearly up to 50% over 2 years. Compared with other instruments and on the prodromal stage of depressive disorder, the ERIraos has shown good predictive capacity. CONCLUSIONS The ERIraos has been successfully employed as a two-step tool for the early recognition of psychosis risk in several German studies and translated into several foreign languages.

Abstract
BACKGROUND One in three people with a chronic somatic disease suffer from a comorbid mental disorder. Most common comorbidities are depressive, anxiety and adjustment disorders. These lead to an increase in morbidity and mortality, and a deterioration of quality of life and healthcare costs. Treatment of mental disorders is of great importance, but the waiting time for outpatient individual psychotherapy can be up to six months in Germany. Group therapy has comparable treatment effects and is considerably more economic than individual therapy; however, it is still almost unused in the outpatient care system. The introduction of a stepped care approach, such as attending a group program before individual therapy, could improve this issue. For this purpose we developed a group program (STEpS), and its efficacy will be evaluated in this study. METHODS/DESIGN A randomized controlled trial will be conducted to evaluate the efficacy of a cognitive behavioral therapy (CBT) group program for patients with somatic diseases and depressive or adjustment disorders, compared to a wait-list control group. A total of 128 adults with any chronic somatic disease and comorbid depression or adjustment disorder will be recruited in our outpatient clinic, and will be randomly assigned to participate in the group program immediately after contacting the clinic (intervention group) or after a waiting period of four months (wait-list control group). Primary outcomes will be self-reported depressive and anxiety symptoms. Secondary outcomes will be self-reported psychological distress, changes in experience and behavior, health-related quality of life, state of self-esteem and subjective need for therapy. Assessments will take place at baseline, 10 weeks (post-treatment) and 18 weeks (follow-up) after randomization. Additionally, treatment acceptance and psychotherapeutic process will be assessed after each session. DISCUSSION This study investigates whether the CBT group program is an effective treatment to reduce depressive and anxiety symptoms and psychological distress in these patients. If the group program is effective, it could be implemented as a treatment option prior to individual outpatient therapy. These results will contribute to improving outpatient care for mental disorders in patients with somatic diseases. TRIAL REGISTRATION German Clinical Trials Register DRKS00005140 (27 August 2013).

Abstract
AIM In November 2005 the Italian Center on Control of Maladies, a department operating under the Ministry of Health, financed a project aimed at evaluating the feasibility of a protocol of intervention based on the early intervention in psychosis (EIP) model within the Italian public mental health-care network. METHODS The study was carried out between March 2007 and December 2009. It involved five centres operating under the Departments of Mental Health of Milan (Programma 2000), Rome (area D), Grosseto, Salerno (Nocera) and Catanzaro (Soverato). RESULTS Enrolment lasted 12 months, at the end of which 43 patients were enrolled as first-episode psychosis (FEP), and 24 subjects as ultra high-risk (UHR) patients. Both FEP and UHR samples included a preponderance of male patients. A family history of psychosis was rarely reported in both samples. The FEP incidence rate was lower than expected on the basis of international estimates of the incidence of schizophrenia but within the expected figure for the estimated Italian rates in three centres out of five. CONCLUSIONS Overall, the study proved that an EIP centre can be established within the public Department of Mental Health to reach a good fraction of the cases in need of treatment. Since then, several studies have been set up to assess the feasibility of EIP in the Italian public mental health sector in Lombardy and Tuscany, and in 2012 the Emilia-Romagna Regional Authority started an educational plan aimed at implementing the EIP model in all the Mental Health Departments in the region.

Abstract
Sex-related differences in the clinical expression and outcome of schizophrenia have long been recognized; this study set out to evaluate whether they extend to those subjects who are at high risk of developing psychosis. In a sample enrolled in two early intervention programs in northern Italy, patients with first-episode psychosis (FEP; n=152) were compared to patients at ultra-high risk of psychosis (UHR; n=106) on a series of sex-related clinical characteristics of schizophrenia. In both the FEP and the UHR samples, males outnumbered females. In FEP patients, women had been referred at an older age than men and had a shorter duration of untreated illness (DUI) and of untreated psychosis. In UHR patients no sex differences were found in age of onset or DUI. There was no diagnosis by sex interaction on symptoms severity or level of functioning at presentation. The limited number of women in both samples, and the exclusion of people who were older than 30 and of those with substance dependence may have reduced the extent of sex-related differences in this study. Sex differences of precipitating factors for psychosis might be worthy of further investigation.

Patterns of referral in first-episode schizophrenia and ultra high-risk individuals: results from an early intervention program in Italy. Soc Psychiatry Psychiatr Epidemiol 2013; 48:1905-16.

Abstract
PURPOSE This study set out to investigate the patterns of referral in a sample (n = 206) of patients having first-time access to an Italian comprehensive program that targets the early detection of and early intervention on subjects at the onset of psychosis. The primary goal of the study was to investigate the duration of untreated illness (DUI) and/or the duration of untreated psychosis (DUP) in the sample since the implementation of the program. METHOD Data on pathways of referrals prospectively collected over a 11-year period, from 1999 to 2010; data referred to patients from a defined catchment area, and who met ICD-10 criteria for a first episode of a psychotic disorder (FEP) or were classified to be at ultra-high risk of psychosis (UHR) according to the criteria developed by the Personal Assessment and Crisis Evaluation (PACE) Clinic in Melbourne. Changes over time in the DUI and DUP were investigated in the sample. RESULTS Referrals increased over time, with 20 subjects enrolled per year in the latter years of the study. A large majority of patients contacted a public or private mental health care professional along their pathway to treatment, occurring more often in FEP than in UHR patients. FEP patients who had contact with a non-psychiatric health care professional had a longer DUP. Over time, DUP and DUI did not change in FEP patients, but DUI increased, on average, in UHR patients. CONCLUSIONS The establishment of an EIP in a large metropolitan area led to an increase of referrals from people and agencies that are not directly involved in the mental health care system; over time, there was an increase in the number of patients with longer DUI and DUP than those who normally apply for psychiatric services.

Abstract
AIM So far, no study has assessed the validity of the Health of the Nation Outcome Scales (HoNOS) in patients enrolled in early intervention programmes, nor has any study evaluated the validity of the HoNOS in people at ultra high-risk (UHR) of psychosis. This study set out to assess the validity and reliability of the HoNOS as a measure of outcome in the patients enrolled in an early intervention programme. METHODS The concurrent, discriminant and predictive validity, and the reliability of the HoNOS as a measure of outcome in an early intervention programe were assessed in 87 first-episode psychosis (FEP) patients, and in 81 patients at UHR of psychosis. RESULTS Reliability indexes were good in the FEP sample, and less good in the UHR sample. HoNOS total scores differentiated between FEP and UHR patients, and the HoNOS subscales proved able to assess a specific profile of symptoms in the two samples, demonstrating a helpful adjunctive measure of health status without complete overlap with other scales. Sensitivity to change was also very good, again with differences between FEP and UHR patients. HoNOS scores at intake did not predict failure to attain remission in FEP patients. There were too few cases of transition to psychosis (n = 2) to assess predictive validity of HoNOS in the UHR sample. CONCLUSION HoNOS possesses satisfactory sensitivity and validity to be used in the routine assessment in early intervention programmes.

Abstract
Mutations in postsynaptic scaffolding genes contribute to autism, thus suggesting a role in pathological processes in neurodevelopment. Recently, two de novo mutations in SHANK3 were described in schizophrenia patients. In most cases, abnormal SHANK3 genotype was also accompanied by cognitive disruptions. The present study queries whether common SHANK variants may also contribute to neuropsychological dysfunctions in schizophrenia. We genotyped five common coding or promoter variants located in SHANK1, SHANK2 and SHANK3. A comprehensive test battery was used to assess neuropsychological functions in 199 schizophrenia patients and 206 healthy control subjects. In addition, an independent sample of 77 subjects at risk for psychosis was analyzed for replication of significant findings. We found the T allele of the SHANK1 promoter variant rs3810280 to lead to significantly impaired auditory working memory as assessed with digit span (12.5 ± 3.6 vs. 14.8 ± 4.1, P < .001) in schizophrenia cases, applying strict Bonferroni correction for multiple testing. This finding was replicated for forward digit span in the at-risk sample (7.1 ± 2.0 vs. 8.3 ± 2.0, P = .044). Previously, altered memory functions and reduced dendritic spines and postsynaptic density of excitatory synapses were reported in SHANK1 knock-out mice. Moreover, the atypical neuroleptic clozapine was found to increase SHANK1 density in rats. Our findings suggest a role of SHANK1 in working memory deficits in schizophrenia, which may arise from neurodevelopmental changes to prefrontal cortical areas.

Abstract
Expressed emotion (EE) was examined in a large sample of families of patients with either first-episode psychosis (FEP) within the schizophrenia spectrum, or who met the criteria for ultra high-risk (UHR) of psychosis. The aim of our study was to determine the patterns and relationship of EE with the duration of untreated illness (DUI) or of untreated psychosis (DUP), as well as with illness severity. The sample used in our study included 77 FEP and 66 UHR families. The Camberwell Family Interview was used to assess EE. In both samples, about one-third of patients' families were classified as high EE, with emotional over-involvement (EOI) being the most frequent reason for a family to be classified as high EE. In FEP, higher EE correlated with longer DUI, and higher paternal EOI with longer DUP. DUI, however, was not found to correlate to EE in UHR patients. Severity of illness at the initial assessment did not relate to EE in either FEP or UHR families. Families of FEP and UHR patients were not found to differ in terms of the prevalence of a high EE rating, or of any of its subcomponents. The results of this study only partially support the hypothesis that high EE develops as a reaction to patient status. Patients from families with high EE could possibly benefit from interventions that are targeted at improving their resilience when dealing with problematic family environments.

Abstract
OBJECTIVE Subjective quality of life (sQoL) and potentially contributing factors were investigated in individuals putatively in an early (EIPS) or late initial prodromal state (LIPS) and healthy controls (HC). METHOD Participants comprised 58 EIPS individuals, 157 LIPS individuals and 87 HC individuals. sQoL was assessed together with locus of control (LoC), coping, demography and psychopathology. RESULTS Putatively prodromal groups exhibited markedly lower sQoL than HC (all domains P < 0.00001). EIPS and LIPS individuals did not differ significantly. Depression was the most consistent explaining variable of sQoL in EIPS and LIPS individuals. In EIPS individuals, LoC emerged as an additional predictor. CONCLUSION Individuals at risk for psychosis experienced a marked impairment of sQoL across all domains. This was evident even in the early state, showed no significant further deterioration during the late state and was predominantly explained by non-specific symptoms.
