Aim: To assess the feasibility of a randomized pilot trial that evaluated the acceptability and potential clinical utility of the Mindfulness Ambassador Program (MAP), a unique, standardized 12-session facilitated group mindfulness-based intervention (MBI) for youth experiencing early psychosis. Method(s): Twenty-one patients of an early psychosis intervention program were randomized to receive MAP (n = 11) or treatment as usual (n = 10). Acceptability was measured by group attendance rate and client satisfaction; feasibility of the study design was measured by the recruitment and retention rate. The means, standard deviations, and 95% confidence intervals were described for outcomes of interest. Result(s): MAP is associated with a high degree of acceptability and has beneficial effects for depression and fatigue. The randomized trial design is feasible. Conclusion(s): This study provides important pilot data supporting a larger randomized trial of effectiveness for MAP as a group MBI for early psychosis. Details of MAP and study limitations are discussed. Copyright © 2018 John Wiley & Sons Australia, Ltd

There are risks associated with the use of antipsychotic medication (AP). These include adverse neurological and metabolic effects and measurable changes in brain structure. APs may even be associated with poorer functional recovery. The STAGES Study is a noninferiority design randomised double blind placebo controlled study that examines whether a subgroup of people with FEP can recover without AP, and considers the effects on functioning, physical health, cognition, and brain structure of AP versus withholding AP. Young people with FEP were screened for study eligibility and recruited if they met stringent inclusion criteria indicating low-risk of harm to self or others, and adequate social support. Participants were randomly assigned to receive either low dose AP (MIPT group) or placebo (PIPT group) for six months, and all participants received intensive psychosocial treatment. Ninety young people (mean age 18.5 years) were randomised and 81 commenced trial medication. Thirty-four percent of participants completed the six month medication phase and there were more completers in the placebo group than the medication group. On the primary outcome measure of SOFAS there was significant evidence that the placebo group was not inferior to the medication group (SOFAS: MIPT mean = 61.5, SD = 13.4; PIPT mean = 61.7, SD = 16.8). The two groups were found to be very similar on all psychopathology assessments and measures of functioning at both baseline and following treatment, suggesting that the outcomes of the two treatment regimes were not different with respect to symptoms and functioning.

BACKGROUND: No established treatment algorithm exists for patients with schizophrenia. Whether switching antipsychotics or early use of clozapine improves outcome in (first-episode) schizophrenia is unknown.
METHODS: This three-phase study was done in 27 centres, consisting of general hospitals and psychiatric specialty clinics, in 14 European countries and Israel. Patients aged 18-40 years who met criteria of the DSM-IV for schizophrenia, schizophreniform disorder, or schizoaffective disorder were treated for 4 weeks with up to 800 mg/day amisulpride orally in an open-label design (phase 1). Patients who did not meet symptomatic remission criteria at 4 weeks were randomly assigned to continue amisulpride or switch to olanzapine (<=20 mg/day) during a 6-week double-blind phase, with patients and staff masked to treatment allocation (phase 2). Randomisation was done online by a randomisation website; the application implemented stratification by site and sex, and applied the minimisation method for randomisation. Patients who were not in remission at 10 weeks were given clozapine (<=900 mg/day) for an additional 12 weeks in an open-label design (phase 3). The primary outcome was the number of patients who achieved symptomatic remission at the final visits of phases 1, 2, and 3, measured by intention-to-treat analysis. Data were analysed with a generalised linear mixed model, with a logistic link and binomial error distribution. This trial is registered with ClinicalTrials.gov, number NCT01248195, and closed to accrual.
FINDINGS: Between May 26, 2011, and May 15, 2016, we recruited 481 participants who signed informed consent. Of the 446 patients in the intention-to-treat sample, 371 (83%) completed open-label amisulpride treatment, and 250 (56%) achieved remission after phase 1. 93 patients who were not in remission continued to the 6-week double-blind switching trial, with 72 (77%) patients completing the trial (39 on olanzapine and 33 on amisulpride); 15 (45%) patients on amisulpride versus 17 (44%) on olanzapine achieved remission (p=0.87). Of the 40 patients who were not in remission after 10 weeks of treatment, 28 (70%) started on clozapine; 18 (64%) patients completed the 12-week treatment, and five (28%) achieved remission. The number of serious adverse events did not differ between the treatment arms in phase 2: one patient on olanzapine was admitted to hospital because of an epileptic seizure, and one patient on amisulpride was admitted to hospital twice because of exacerbations of psychotic symptoms. Over the course of the trial, two serious suicide attempts were reported.
INTERPRETATION: For most patients in the early stages of schizophrenia, symptomatic remission can be achieved using a simple treatment algorithm comprising the sequential administration of amisulpride and clozapine. Since switching to olanzapine did not improve outcome, clozapine should be used after patients fail a single antipsychotic trial-not until two antipsychotics have been tried, as is the current recommendation.

AIM: The effects of nutrient-based treatments, including adjunctive vitamin or antioxidant supplementation, have been explored extensively in long-term schizophrenia. However, no systematic evaluation of trials in "first-episode psychosis" (FEP) has been conducted, despite the potential benefits of using these treatments during the early stages of illness. Therefore, we aimed to review all studies examining efficacy, tolerability and the biological mechanisms of action, of nutrient supplementation in FEP.
METHODS: A systematic review of electronic databases was conducted from inception to July 2017. All information on feasibility, clinical outcomes and mechanistic findings from nutrient supplementation clinical trials was extracted and systematically synthesized.
RESULTS: Eleven studies with a total of 451 patients with FEP (from 8 independent randomized controlled trials) were eligible for inclusion. Six studies examined omega-3 fatty acids, with inconsistent effects on psychiatric symptoms. However, mechanistic studies found significant improvements in hippocampal neuronal health and brain glutathione. Antioxidants "n-acetyl cysteine" (n = 1) and vitamin C (n = 2) also improved oxidative status in FEP, which was associated with reduced psychiatric symptoms. No benefits were found for vitamin E (n = 1). Finally, one study trialling the amino acid taurine, showed significant improvements in positive symptoms and psychosocial functioning.
CONCLUSION: There is preliminary evidence that taurine improves outcomes in FEP, whereas effects of omega-3 and antioxidant vitamins/amino-acids are inconsistent; perhaps mainly benefitting patients with high levels of oxidative stress. Future studies should evaluate multifaceted dietary and supplementation interventions in FEP; targeting-specific nutritional deficits and the range of aberrant biological processes implicated in the disorder.

Whether to discontinue or continue antipsychotics medication in remitted first-episode psychosis is a difficult clinical decision. Consistent short-term evidence suggests that maintenance medication is effective in relapse prevention. However, long-term outcome data are lacking; with only one open-label study suggesting better recovery outcome in patients who had early dose reduction/discontinuation. We examined the long-term effect of early medication discontinuation in a remitted first-episode psychosis cohort in Hong Kong. We followed-up 178 first-episode psychosis patients who had previously participated in a 12-month randomized controlled trial on medication discontinuation (placebo) or continuation (quetiapine). Following the trial, all patients received usual psychiatric care. Poor clinical outcome was defined as a composite of persistent psychotic symptoms, a requirement for clozapine, or suicide at 10 years. We found no significant differences between patients who were successfully traced after 10 years (n = 142) and those who were not (n = 36) in terms of their basic demographics, symptoms and functioning at baseline. At 10 years, more patients in the early discontinuation group (35 of 89, 39%) had poor clinical outcome than patients in the maintenance group (19 of 89, 21%) (P<0.01). Relapse during the randomized trial had partly mediated the significant relationship between early medication discontinuation and poor outcome (P = 0.003). In first episode psychosis with a full initial response to antipsychotic treatment, continued need for maintenance medication is important for the first three years after starting treatment, so as to prevent relapse, and to decrease the risk for a poor long-term outcome.

OBJECTIVE: No consensus exists on whether clozapine should be prescribed in early stages of psychosis. This systematic review and meta-analysis therefore focus on the use of clozapine as first-line or second-line treatment in non-treatment-resistant patients.
METHODS: Articles were eligible if they investigated clozapine compared to another antipsychotic as a first- or second-line treatment in non-treatment-resistant schizophrenia spectrum disorders (SCZ) patients and provided data on treatment response. We performed random-effects meta-analyses.
RESULTS: Fifteen articles were eligible for the systematic review (N = 314 subjects on clozapine and N = 800 on other antipsychotics). Our meta-analysis comparing clozapine to a miscellaneous group of antipsychotics revealed a significant benefit of clozapine (Hedges' g = 0.220, P = 0.026, 95% CI = 0.026-0.414), with no evidence of heterogeneity. In addition, a sensitivity analysis revealed a significant benefit of clozapine over risperidone (Hedges' g = 0.274, P = 0.030, 95% CI = 0.027-0.521).
CONCLUSION: The few eligible trials on this topic suggest that clozapine may be more effective than other antipsychotics when used as first- or second-line treatment. Only large clinical trials may comprehensively probe disease stage-dependent superiority of clozapine and investigate overall tolerability.

Psychoeducation of persons living with psychotic illness and their family caregivers is a long-standing and effective means of providing information and support that benefits both families and those living with illness. However, cultural adaptation of psychoeducation and integration into routine care in settings with very low mental health resources is rare. Purpose(s): This presentation aims to describe outcomes of an investigation of the effectiveness of a culturally-adapted, brief interactive psychoeducation intervention for family caregivers in Java, and to study the feasibility of integrating such interventions into routine mental health services provided by primary health care providers. Method(s): An experimental study was conducted with pre-test and post-test assessments with 100 persons living with first episode psychotic illness and their family caregivers. Families were randomly assigned to intervention and control groups, and psychiatric residents were trained to administer 4 weekly interactive psychoeducation sessions with modules adapted for the local cultural setting. When the intervention was found to be feasible and effective, a program was developed to train staff in three primary health centers to provide a similar intervention for individuals and families registered with the primary health care center. Finding(s): The initial intervention was found to be feasible and effective, particularly in increasing Knowledge of Schizophrenia of family members and reducing rehospitalization. Training of primary health care workers was found to be feasible and effective. Conclusion(s): Adapting psychoeducation for individuals with psychotic illness and family caregivers is feasible and can be integrated into primary health services in low resource settings.

Backgrounds: There is a debate regarding the optimal timing of discontinuation of antipsychotic drugs in patients with first episode psychosis (FEP) or schizophrenia. We aimed to provide a review of the literature on which strategy (medication maintenance vs. dose reduction/discontinuation) is more likely to maximize outcomes, such as cognition and social function. Method(s): Using PubMed, the Cochrane Library and systematic reviews, articles published between 2007 and 2018 were reviewed, which investigated the effect of dose reduction/discontinuation vs. maintenance treatment on measures of cognition and/or social function in FEP and schizophrenia. Result(s): Six studies were identified; 2 studies reported on cognition while 4 studies concern social function. All studies except one reported that improvement of functional outcomes in remitted patients with FEP or schizophrenia allocated to a dose reduction/discontinuation arm was equal to or better than that in patients for whom medication doses were maintained. One trial of social function with a 1-year follow-up period found a greater improvement in the medication maintenance group, while no group difference was observed with 3-year and 10-year follow-up periods. On the other hand, a 7-year follow-up study found a superiority for the dose reduction/discontinuation regimen in terms of social outcome. Two studies on cognition with a short follow-up period reported a greater improvement for the dose reduction/discontinuation group. Conclusion(s): Information on cognition and social function has been relatively sparse. These measures of functional outcome should be considered in deciding which strategy of antipsychotic treatments is beneficial in individual cases with FEP or schizophrenia.

Background: Negative and cognitive symptoms are core features of schizophrenia and contribute to the marked functional deficits and poor quality of life associated with this illness. Currently approved medications for schizophrenia, however, are relatively ineffective for these symptom domains. N-Acetyl Cysteine (NAC) is a neuroprotective agent that mitigates the deleterious effects of oxidative stress, inflammation and glutamatergic toxicity. Because of its unique mechanisms of action, NAC has been investigated in several clinical trials in schizophrenia. While there is agreement that NAC appears ineffective for positive symptoms, the outcomes data for negative symptoms and cognitive impairment are conflicting. Method(s): In this paper, we assessed the effects NAC (3600 mg/day) in a 52-week, double-blind, placebo controlled trial in early phase schizophrenia spectrum disorders (N = 60). Result(s): NAC significantly improved (time x group) PANSS negative symptoms (F = 5.1, p = 0.024), as well as PANSS total (F = 14.7, p<0.001) and disorganized thought (F = 13.7, p<0.001) symptom scores. NAC failed to improve BACS cognitive total composite and individual cognitive test scores, as well as PANSS positive symptom scores. Baseline right (r = -0.48, p = 0.041) and left (r = -0.45, p = 0.018) total cortical thickness, and thickness in other cortical regions, were associated with NAC related improvement in symptom scores. Conclusion(s): These results replicate some but not all previous findings of NAC efficacy. The discrepancies among NAC studies for negative and cognitive symptom results will be addressed with suggestions to reconcile these differences.

Cognitive Enhancement Therapy (CET) has shown substantial and lasting effects on neurocognition in schizophrenia. This ongoing study compares the effects and durability of CET to an Enriched Supportive Therapy (EST) control condition in early-course schizophrenia (ES). Prior pilot findings from this study suggested differential neurocognitive improvements favoring CET but have not yet examined the role of hedonic capacity (HC) on these effects. ES outpatients were randomized to CET or EST as part of a 2.5-year randomized-controlled trial. Neurocognition was assessed with the MATRICS Consensus Cognitive Battery (MCCB) and HC was evaluated with pleasantness ratings on the Modified Brief Smell Identification Test. Linear mixedeffects analyses were performed on data from 67 participants at baseline (41 CET, 26 EST) and 37 at 9 months (21 CET, 16 EST). Preliminary results confirmed previous findings of a significant time x group interaction favoring CET on the MCCB Composite score. Of note, there was a main effect for HC in both groups, indicating that those with the largest ranges of ratings between the most pleasant and unpleasant odors showed better neurocognitive performance in their respective conditions. These initial findings continue to suggest that CET is effective in ES, but that the extent of neurocognitive improvement may be partially moderated by HC. Considering the critical role of hedonic and other reward processes in learning, these findings have important implications for incorporating targeted reward-enhancing interventions in cognitive rehabilitation for people with ES. As data for this study accrues, the durability of these effects can be examined further.

Social cognition is a key determinant of functional outcomes in early course schizophrenia. The goal of our study was to examine the impact of cognitive enhancement therapy (CET) on social cognition and on functional connectivity in early course schizophrenia. Eightyfour participants were randomly assigned to either treatment groups (CET, n = 49; Enriched Supportive Therapy (EST), n = 35). Resting state scans and social cognition performance, as measured by the MATRICS battery, were collected at baseline, 9, 18 and 30 months. We conducted mixed linear model analyses to investigate the impact of treatment (CET vs. EST) on social cognition and on the dorsolateral prefrontal cortex (DLPFC) functional connectivity to the right and left amygdala. CET group showed significant improvement over time in social cognition in comparison to the EST group (p<.05). Change in functional connectivity over time did not significantly differ between treatments. However, we observed a significant positive correlation between increased right DLPFC functional connectivity to the right amygdala and social cognition performance in the CET group (p<.05). Our results replicate previous work demonstrating that CET is effective at improving social cognition in schizophrenia. In addition, we found evidence that this improvement could be reflected in the DLPFC-amygdala circuit connectivity. This neural circuit potentially provides a mechanistic link between the biology of emotion regulation and more complex social cognition processes that can be improved in early stage of the illness.

Background Cognitive behavioural therapy (CBT) for psychosis is a distinct type of psychotherapy that has been recommended together with antipsychotic drugs and comprehensive usual care in the management of schizophrenia, a complex mental health disorder associated with a high economic and societal burden. The objectives of this report were to assess the effectiveness, harms, cost-effectiveness, and lived experience of CBT for psychosis in improving outcomes for adults with a primary diagnosis of schizophrenia. Methods We performed literature searches on March 28 and April 5, 2017, and undertook a qualitative synthesis of systematic reviews of the clinical and economic literature comparing CBT for psychosis with any comparator interventions (e.g., usual care, waitlist control, or pharmacotherapy) in adults with a diagnosis of schizophrenia as defined by any criteria (including related disorders such as schizoaffective disorder). We developed an individual-level state-transition probabilistic model for a hypothetical cohort of adults aged 18 years and older starting with first-episode psychosis. We compared three strategies: usual care, CBT for psychosis by physicians, and CBT for psychosis by regulated nonphysician therapists. The CBT was provided in person together with usual care including pharmacotherapy: 16 structured sessions (individual or group) for first-episode psychosis and 24 individual sessions for relapse or treatment-resistant disease. We calculated incremental cost-effectiveness ratios (ICERs) over 5 years using the Ontario Ministry of Health and Long-Term Care perspective and a discount rate of 1.5%. We also estimated the 5-year budget impact of publicly funding CBT for psychosis in Ontario. In addition, we interviewed 13 people with lived experience of schizophrenia and psychosis about their values and preferences surrounding CBT and other treatments. Results CBT for psychosis compared with usual care significantly improved overall psychotic symptoms (standard mean difference [SMD] -0.33, 95% confidence interval [CI] -0.45 to -0.21), positive symptoms (e.g., hallucinations) (SMD -0.34, 95% CI -0.58 to -0.10), auditory symptoms (SMD 0.39, 95% CI not reported, P <.005), delusions (SMD 0.33, 95% CI not reported, P <.05) and negative symptoms (e.g., blunt affect) (SMD -0.32, 95% CI -0.59 to -0.04) at end of treatment. No significant differences were observed for social function, distress associated with psychosis, relapse, or quality of life. Compared with any control, CBT for psychosis significantly improved overall psychotic symptoms, positive symptoms, auditory hallucinations, delusions, and negative symptoms. Compared with other forms of therapy, CBT for psychosis showed inconsistent results at end of treatment for overall psychotic symptoms, positive symptoms, auditory hallucinations, and delusions. In people with first-episode psychosis, CBT for psychosis was not significantly more effective for the prevention of relapse when compared with other forms of therapy or usual care (odds ratio [OR] 1.11, 95% CI 0.63-1.95 and OR 1.15, 95% CI 0.65-2.04, respectively). Low-intensity CBT for psychosis (fewer than 16 face-to-face sessions) compared with any type of treatment significantly improved overall psychotic symptoms and social function at follow-up (SMD -0.40, 95% CI -0.74 to -0.06 and SMD -0.57, 95% CI -0.81 to -0.33, respectively). In the cost-utility analysis, CBT for psychosis provided by nonphysician therapists compared with usual care was associated with increases in both quality-adjusted life-years (mean 0.1159 QALYs, 95% credible interval [CrI] 0.09-0.14) and costs (mean $2,494, 95% Crl $1,472- $3,544), yielding an ICER of $21,520 per QALY gained. CBT for psychosis provided by physicians was dominated because it was equally effective but more expensive (mean $2,976, 95% CrI $2,822-$3,129; ICER of CBT for psychosis vs. usual care: $47,196/QALY gained). Assuming a 20% increase in access per year (from 0% at baseline to 100% in year 5), we estimated the total 5-year net budget impact of publicl funding CBT for psychosis would be about $15.2 million for nonphysician providers and about $35.4 million if provided by psychiatrists. It is estimated that by the year 2021, approximately 110 nonphysician therapists or 150 physicians would be needed to provide CBT for psychosis to more than 12,000 adults with schizophrenia (including about 8,500 incident cases) in Ontario. People with schizophrenia and their family members reported positive experiences with CBT for psychosis. They felt it provided effective tools to help manage their schizophrenia but stressed that it was only effective in conjunction with medication to control psychotic episodes and overcome a patient's denial of illness. Geographic and financial barriers have restricted access to this psychotherapy. Conclusions Compared with usual care or any control, CBT for psychosis significantly improved psychotic symptoms, based on evidence of moderate to adequate quality; no significant improvements were observed for social function, relapse, or quality of life outcomes. People affected by schizophrenia reported that CBT for psychosis was valuable in conjunction with antipsychotic medication but that access to this type of psychotherapy is limited. Adding CBT for psychosis to usual care in the management of adult schizophrenia probably represents good value for money in Ontario. Depending on the type of provider, therapy format, and rate of access, the net budget impact to Ontario's publicly funded health system would likely be between $15 million to $35 million over the next 5 years.
