Background: We previously demonstrated that the high heterogeneity of response to\rcomputerized Auditory Training (AT) in psychosis can
be ascribed to individual differences in sensory processing efficiency and neural plasticity. In particular, we showed that Auditory Processing Speed
(APS) serves as a behavioral measure of target\rengagement, with faster speed predicting greater transfer effects to untrained cognitive\rdomains.
Here, we investigate whether the ability of APS to function as a proxy for target\rengagement is unique to AT, or if it applies to other training
interventions, such as\rExecutive Functioning Training (EFT). Additionally, we examine whether changes in APS\rare durable after these two forms of
training.\rMethods: One hundred and twenty-five participants with Recent Onset Psychosis (ROP)\rwere randomized to AT (n = 66) and EFT (n = 59),
respectively. APS was captured at\rbaseline, after treatment, and at 6-month follow-up. Mixed models repeated measures\ranalysis with restricted
maximum likelihood was used to examine whether training\rcondition differentiated APS trajectories. Within-group correlational analyses were used\rto
study the relationship between APS and performance improvements in each of the\rtraining exercises.\rResults: The two groups were matched for age,
gender, education, and baseline APS.\rParticipants showed high inter-individual variability in APS at each time point. The mixed\rmodel showed a
significant effect of time (F = 5.99, p = .003) but not a significant groupby-time effect (F = .73, p = .48). This was driven by significant APS
improvements AT patients after treatment (d = .75) that were maintained after 6 months (d = .63).\rConversely, in EFT patients, APS improvements did
not reach statistical significance\rafter treatment (p = .33) or after 6 months (p = .24). In AT patients, baseline APS (but not\rAPS change) highly
predicted peak performance for each training exercise (all r's >.42).Conclusions: Participant-specific speed in processing basic auditory stimuli
greatly varies in ROP, and strongly influences the magnitude of response to auditory but not executive functioning training. Importantly, enhanced
auditory processing efficiency persists 6 months after AT, suggesting the durability of neuroplasticity processes induced by this form of training.
Future studies should aim to identify markers of target engagement and durability for cognitive training interventions that target sensory modalities
beyond the auditory domain.

Aim: Attenuated
psychotic symptoms (APSs) have been the primary emphasis in youth at clinical high risk (CHR) for psychosis for assessing symptomology and
determining subsequent transition to a psychotic disorder. Previous reviews primarily focused on the efficacy of cognitive behavioural therapy (CBT)
on APS; however, a comprehensive assessment of other interventions to date is lacking. Therefore, we conducted a systematic review and meta-analysis
of all intervention studies examining APS in CHR youth. Method(s): The authors searched Embase, CINAHL, PsycINFO, Medline and EBM from inception to
May 2017. Studies were selected if they included any intervention that reported follow-up APS in youth at CHR. Interventions were evaluated and
stratified by time using both pairwise and network meta-analyses (NMAs). Due to the differences in APS scales, effect sizes were calculated as Hedges
g and reported as the standardized mean difference (SMD). Result(s): Forty-one studies met our inclusion criteria. In pairwise meta-analyses, CBT was
associated with a trend towards reduction in APS compared to controls at 12-months. In the NMA, integrated psychological therapy, CBT, supportive
therapy, family therapy, needs-based interventions, omega-3, risperidone plus CBT and olanzapine were not significantly more effective at reducing
APS at 6 and 12 months relative to any other intervention. Conclusion(s): CBT demonstrated a slight trend at reducing APS at long-term follow-up
compared to controls. No interventions were significantly more effective at reducing APS compared to all other interventions in the NMA. [Correction

Objectives Current service organization is not adapted for youth with or at risk of mental illness. Access,
engagement and continuity of care are notorious challenges, particularly during transition from adolescence to adulthood, when youths are transferred
to adult services. An HTA was initiated to evaluate the efficacy of programs for which admission is not a function of the legal age of
majority.Methods A systematic review of systematic reviews identified literature published between 2000 and 2017 in 4 databases. To be selected,
studies had to focus on specialised mental healthcare early intervention (EI) programs targeting both adolescents and young adults. Contextual and
experiential data were collected through interviews with local leading experts. Article selection and quality assessment using ROBIS were conducted
with inter rater agreement. The analytical framework developed includes 4 domains: access, engagement and continuity, recovery as well as
meaningfulness and acceptability.Results 1841 references were identified. Following inclusion/exclusion criteria, 5 studies were selected, 3 of which
focused on EI for psyschosis. EI programs alone do not seem to decrease duration of untreated psychosis. EI including a multi focus campaign were
more successful. EI does, however, seem to decrease hospitalisation for psychosis. The experience of service users and professionals with inter
agency collaboration and person-centred care models were analysed to identify facilitating and inhibiting implementation factors.Conclusions
Healthcare policies need to support further research and development of EI where admission is not a function of the legal age of majority and
diagnostic, particularly for youths at risk. Copyright © Cambridge University Press 2019.

Background: Elevated homocysteine is observed in schizophrenia and associated
with illness severity. The aim of this study was to determine whether vitamins B12, B6, and folic acid lower homocysteine and
improve symptomatology and neurocognition in first-episode psychosis. Whether baseline homocysteine, genetic variation, sex, and diagnosis interact
with B-vitamin treatment on outcomes was also examined. Method(s): A randomized, double-blind, placebo-controlled trial was used. A total of 120
patients with first-episode psychosis were randomized to an adjunctive B-vitamin supplement (containing folic acid [5 mg], B12 [0.4 mg],
and B6 [50 mg]) or placebo, taken once daily for 12 weeks. Coprimary outcomes were change in total symptomatology (Positive and Negative
Syndrome Scale) and composite neurocognition. Secondary outcomes included additional measures of symptoms, neurocognition, functioning, tolerability,
and safety. Result(s): B-vitamin supplementation reduced homocysteine levels (p = .003, effect size = -0.65). B-vitamin supplementation had no
significant effects on Positive and Negative Syndrome Scale total (p = .749) or composite neurocognition (p = .785). There were no significant group
differences in secondary symptom domains. A significant group difference in the attention/vigilance domain (p = .024, effect size = 0.49) showed that
the B-vitamin group remained stable and the placebo group declined in performance. In addition, 14% of the sample had elevated baseline homocysteine
levels, which was associated with greater improvements in one measure of attention/vigilance following B-vitamin supplementation. Being female and
having affective psychosis was associated with improved neurocognition in select domains following B-vitamin supplementation. Genetic variation did
not influence B-vitamin treatment response. Conclusion(s): While 12-week B-vitamin supplementation might not improve overall psychopathology and
global neurocognition, it may have specific neuroprotective properties in attention/vigilance, particularly in patients with elevated homocysteine
levels, patients with affective psychosis, and female patients. Results support a personalized medicine approach to vitamin supplementation in
first-episode psychosis. Copyright © 2019 Society of Biological Psychiatry

Backgrounds: Social cognition
deficits are a core feature of schizophrenia and deteriorate functionality of patients. However, evidence is sparse for the treatment effect on
social cognition impairments in the early stage of psychosis. Here, we provide a systematic review of the literature on social cognitive impairment
in early psychosis in relation to its intervention. Methods: A literature search was conducted on English articles identified by Web of
Science and PubMed databases, according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)
statement. Results: Five papers met the inclusion criteria.

Aim: The main goal of this study was to evaluate the effectiveness of a cognitive motivational treatment program. Method(s): A
randomized, controlled, single-blind clinical trial was carried out. A total of 104 patients were recruited to take part in the trial, of whom
ultimately 62 patients were allocated into two groups and finished the study. An initial assessment was carried out before patients were randomly
placed in one of two groups for the clinical trial: (a) PIPE program plus routine care; and (b) routine care only. Clinical assessments were
performed at baseline at 6 months, 1 year and follow-ups, at 18 months and 5 years). Result(s): MANCOVA analysis of tests repeated 18 months after
the start of the intervention detected significant differences between the two groups in terms of clinical variables, everyday functioning and
relapses. These differences remained upon follow-up measurements taken five years after the start of the trial. Conclusion(s): The present study
offers scientific evidence for cognitive-motivational therapy's effectiveness as a treatment for clinical symptoms in the early stages of psychosis.
PIPE intervention may contribute to long-term clinical improvement and stability. Copyright © 2019

BACKGROUND: Specialized early intervention (EI) following a first episode of psychosis (FEP) are
effective at reducing negative symptoms, although its trajectory warrants systematic assessment. However, findings are equivocal as to whether
extended gains are made post 2 years of EI and whether there is additional benefit of extending EI for an additional 3 years. METHOD(S): Data on 178
FEP patients, from a randomized controlled trial of a 3-year extension of EI service v. transfer to regular care following 2 years of EI service,
were used for this report. Repeated measures analysis of variance were conducted separately for the initial 2 years of treatment in an EI service,
and for the 3-year post-randomization to examine trajectories of negative symptoms over the two periods in the two arms of the study. RESULT(S):
There were significant improvements in total negative symptoms over the first 2 years of EI F(4.612, 797.905) = 25.263, p < 0.001 and in domains of
'expressivity' and 'motivation'. In the following 3 years, there were further significant improvements in negative symptoms F(4.318, 759.908) =
4.182, p = 0.002 with no difference between groups F(4.318, 759.908) = 1.073, p = 0.371. Changes in negative symptoms over the extension period were
driven by expressivity F(4.01, 674.73) = 7.19, p < 0.01, but not motivation F(6.58, 1112.18) = 0.95, p = 0.46. CONCLUSION(S): Negative symptoms
improve significantly over the first 2 years of EI. Subsequent amelioration was largely the result of expressivity. Motivation deficits remained
stable. Extended EI offered no advantage over regular care post-randomization.

Omega-3 treatment studies for
multi-episode schizophrenia or clinical high risk for conversion to psychosis states have had variable, and often negative, results. To examine
adjunctive omega-3 treatment for recent onset psychosis, participants aged 15-40 years with recent onset schizophrenia-spectrum (n = 46) or bipolar
(n = 4) disorders and current psychotic symptoms were treated for 16 weeks with risperidone and randomly-assigned omega-3 (EPA 740 mg and DHA 400 mg
daily) or matching placebo. The primary outcome measure was the Brief Psychiatric Rating Scale (BPRS) total score. Mean lifetime antipsychotic
exposure was 18.1 days. Length of time in treatment, risperidone dose and number of omega-3/placebo capsules taken did not differ between conditions.
Longitudinal analysis of the total BPRS score revealed a trend level (p = 0.0826) treatment effect favoring omega-3 treatment. Lorazepam was an
allowed concomitant medication. Among the subgroup (N = 23) who did not receive lorazepam, the treatment effect on BPRS total scores favoring omega-3
was significant (p = 0.0406) and factor scores analyses revealed a substantial decrease in depression-anxiety with omega-3 but no change with placebo
(treatment-by-time interaction, p = 0.0184). Motor side effects did not differ between conditions. Analysis of Systematic Assessment for Treatment
Emergent Events assessments revealed fewer adverse events overall with omega-3 compared with placebo with the largest differences between conditions
(all favoring omega-3) on confusion, anxiety, depression, irritability, and tiredness/fatigue. These results suggest that omega-3 adjuvant treatment
is a potential option for depression and anxiety symptoms of people with recent onset psychosis. Further research is needed to confirm this
potential. (PsycINFO Database Record (c) 2019 APA, all rights reserved)

BACKGROUND: Clozapine is a second-generation antipsychotic typically used
for refractory schizophrenia or otherwise psychotic pathology. There are no FDA or manufacturer guidelines for use of clozapine in pediatric
population. We investigated the current state of research concerning the use of clozapine in pediatric patients.\rAREAS OF UNCERTAINTY: We describe
consistent calls for more research into the long-term and short-term effects of clozapine use in a young patient population. Despite the strongly
supported efficacy, questions concerning clear indications for use and risk-benefit analysis persist. We acknowledge that a more comprehensive meta-
analysis would greatly benefit the field. However, this is the first article of its kind for clozapine in recent history, and therefore, serves as a
focus and reference point for future, more in-depth analyses.\rDATA SOURCES: We conducted a search of PubMed, ClinicalKey, PsycINFO, and MEDLINE
databases. Keywords used included, in varying combinations: clozapine, off-label, indications, children and adolescent, pediatric, behavioral,
suicidality, psychosis, early and very-early onset schizophrenia, side-effect profile, and long-term use. Further criteria and selection are
described in Methods below.\rRESULTS: We describe the documented efficacy of clozapine for the management of refractory psychotic and nonpsychotic
symptoms in the pediatric population. The authors highlight the risk of unmanaged early-onset schizophrenia, aggressive or suicidal behavior, and
severe nonpsychotic pathology. Unfortunately, these studies are generally small. There is little consistency in when clozapine is prescribed, how
long it is administered, and how long patients are followed. Despite the lack of FDA and manufacturer guidelines, clozapine continues to be used for
the benefit of young patients.\rCONCLUSIONS: Indications for prescription of clozapine should be revisited, given the data presented in this
manuscript of a low risk-benefit ratio for properly chosen patients. Larger studies should be conducted to provide more statistical power and
determine clear guidelines for use, risk of side effects, and long-term adverse events that may arise.

Aim: The primary aim was to demonstrate
adherence to a novel 6-week lifestyle intervention program (\"Meals, Mindfulness, & Moving Forward\" [M3]) designed to help improve
lifestyle practices of youth with a history of at least 1 psychotic episode. Method(s): M3 used a non-equivalent control group design
involving clients from a community early intervention program. Seventeen individuals in the active M3 program and 16 controls were
assessed for secondary outcomes at baseline, 6-weeks, and 12-weeks (6 weeks post-intervention) on cardiometabolic and symptomatic outcomes. Result
(s): The program met its primary aim with 88% (15/17) of participants meeting adherence criteria. Compared with the controls, M3
participants showed significant improvement in positive psychotic symptoms (P =.002). Conclusion(s): This pilot study showed that young people
involved in a community early intervention program adhered to an activity-based lifestyle program which included mindfulness meditation, yoga and
nutrition education, warranting further evaluation with a larger sample size. Copyright © 2018 John Wiley & Sons Australia, Ltd

Background: Schizophrenia is among the
most debilitating disorders in the US [1], being associated with high disability [2], and enormous personal and societal cost [3]. Since people with
early-phase schizophrenia generally respond better to treatment, the value of early optimized treatment has long been debated. Early Intervention
Services (EIS) aim at both symptom reduction, improving functional outcomes, and reducing long-term disability during what has been called a
\"critical illness period\". A recent meta-analysis (studies = 10, n = 2,176) comparing EIS versus treatment as usual (TAU) found that EIS
outperformed TAU regarding all meta-analyzable outcomes [4]. However, the optimal EIS treatment duration and the question whether effects pertain
after EIS discontinuation remain unclear. Aim(s): To determine the maintenance of effects after discontinuation of EIS vs TAU and to compare the
continuation of EIS to step-down/ less intense maintenance treatment. Method(s): Systematic literature search of
PubMed/MEDLINE/PsycInfo/clinicaltrials.gov until 04/01/2018 for (i) long-term follow-up data of randomized controlled trials comparing EIS and TAU in
early psychosis, and (ii) randomized controlled trials comparing the continuation of EIS versus step-down/less intense maintenance treatment. Two
independent investigators extracted data for a random effects meta-analysis. Result(s): Three trials followed patients after cessation of EIS
(follow-up: EIS-patients = 59.6% (224/376); TAU -patients = 60.5% (221/365), without any significant EIS vs TAU group differences regarding
individually reported outcomes. Moreover, meta-analyzable outcomes were non-significant, including >=1 psychiatric hospitalization (studies = 2, n =
592, EIS = 132/303, 43.6%; TAU = 138/289, 47.8%; RR = 0.87, 95%CI = 0.68-1.09, p = 0.226), number of hospitalizations (studies = 2, n = 144, SMD =
0.05, 95%CI = -0.34-0.45, p = 0.788), and number of bed days (studies = 3, n = 691, SMD = -0.08, 95%CI = -0.23-0.07, p = 0.282). These non-
significant findings were in contrast to significant superiority of EIS in these same 2-3 studies at the end of the active EIS intervention. Three
trials compared continuation of EIS to less intense maintenance treatment. One study found superiority of extended EIS for adherence, work alliance
and patient satisfaction, while treatment effects remained stable in both groups, while another study found a significant effect of EIS on treatment
duration and both positive and negative symptom remission. The third study indicated superiority of a 12 month-extended EIS for several outcomes,
such as negative and depressive symptoms, general psychopathology, global functioning, independent living skills, and work productivity. As primary
data of these studies are requested, meta-analytic calculations are expected to be available at the conference. Conclusion(s): Our results indicate
that 9-24 months of EIS are insufficient to ensure maintenance effects of early intervention for early psychosis patients. Since only 3 studies
collected data after EIS discontinuation, the non-significant findings could be due to insufficient power. However, pooled results at the end of
active EIS of just these 2-3 studies yielded significant superiority for EIS, despite the low number of subjects/studies. Results of continued EIS vs
step-down treatment clearly confirm the need for continuation of EIS. Sustaining gains achieved by EIS may very well be cost-effective, yet longer-
term effects of EIS applied for >2 years need to be examined. Moreover, these findings question the common believe of a \"critical period\" for early
interventions and guidelines focusing on continued treatment only for the first two years. Copyright © 2018

The present study aimed to provide preliminary evaluation of the effectiveness of a brief CBT intervention
focusing on relapse prevention and positive symptom in a Chinese first episode schizophrenia (FES) population. This randomized controlled trial
recruited eighty outpatients with FES (as determined using the DSM-IV), aged 16-45 years, and on a current atypical antipsychotic. Patients were
randomized to either 10 sessions of individual CBT (intervention group) adjunctive to treatment as usual (TAU) or TAU alone (control group). Outcome
assessment of symptoms, relapse, hospitalization, insight and social functioning were administered at baseline and then post treatment (10 weeks),
and at 6-month and 12-month follow ups. At 12 months, patients in the intervention group had significantly greater improvements in positive symptoms,
general psychopathology and social functioning, as well as significantly lower rates of relapse, compared to the control group. Although patients in
both groups demonstrated significantly improved negative symptom and insight scores from baseline, no group differences were found. This RCT
demonstrates that FES patient can greatly benefit from CBT designed to target relapse prevention and positive symptom, with improvements sustained
for 1 year following treatment.
