Duration of untreated psychosis as predictor of long-term outcome in schizophrenia: systematic review and meta-analysis

The effects of childhood adversity on treatment delays and its components in first-episode psychosis

Apart from increasing risk for psychotic disorders, childhood adversity has been associated with worse outcomes. One way in which childhood adversity may worsen outcomes is by lengthening treatment delays, which are associated with negative impacts. We tested the influence of childhood trauma on treatment delays, measured as the duration of untreated psychosis (DUP), and its help-seeking and referral components, in a first-episode psychosis cohort (N = 203). We accounted for pertinent social (e.g., migrant status) and other determinants (i.e., age at onset, diagnosis, symptoms) of treatment delays. Multiple linear regression analyses revealed that for a one-unit increase in Childhood Trauma Questionnaire (CTQ) scores, average overall DUP increased by 25%. Higher CTQ scores also significantly predicted help-seeking and referral DUPs. Patients with schizophrenia-spectrum psychosis had longer help-seeking and total DUPs than those with affective psychosis. More severe positive symptoms predicted longer help-seeking DUPs, while more severe negative symptoms predicted longer referral DUPs. Indicators of social disadvantage did not affect DUP. Our results show that childhood trauma increases DUP by prolonging the help-seeking process and delaying access to mental healthcare even after help is sought. Early identification of psychosis among populations with trauma histories seems warranted and can likely positively impact outcomes.

Outcomes for first-episode psychosis after entry via an at-risk mental state clinic compared to direct entry to a first episode of psychosis service: A systematic review and meta-analysis

OBJECTIVE

Early intervention for psychosis services have been established worldwide and consist of specialist services for those with the At-Risk Mental State (ARMS) and a first episode of psychosis (FEP). This systematic review identified the literature on the outcomes of people who initially presented via an ARMS clinic and later transitioned to a psychotic disorder (UHR-T), compared to those who presented directly to an EI service with a FEP (FEP-D). The outcomes examined were (i) symptomatic (ii) functional, (iii) morbidity and mortality (including physical health) and (iv) service-usage.

METHOD

A systematic search strategy was employed using three databases: MEDLINE, PsycInfo, and EMBASE. Studies published in English and that compared any of the above outcomes in a cohort of people with a first episode of psychosis who initially presented via an ARMS clinic to those who presented directly to a FEP service were included. Meta-analysis was performed for any outcome data from at least two studies.

RESULTS

A total of 988 unique articles were identified and of these, three studies fulfilled the inclusion criteria and these included a total of 78 UHR-T and 253 FEP-D individuals. In the one study examining remission rates, there was no difference observed after one year in the UHR-T and FEP-D groups. In the one study that examined neurocognition, no differences were observed in any of the neurocognitive domains between groups after one year. Two studies examined psychiatric admission rates within one year and one of these found that UHR-T individuals were less likely to have any psychiatric admission (46% vs 68%) and admissions were less likely to be involuntary (30% vs 74%), while the other study found no difference in admission rates. In the meta-analysis, UHR-T individuals had lower odds for any psychiatric hospital admission within one year compared to FEP-D individuals (OR = 0.54, 95% C.I. 0.32 - 0.94, p = .03). No studies examined functional outcomes or mortality and morbidity between the groups.

CONCLUSION

The limited research indicates similar or superior outcomes for people with a FEP who present initially via an ARMS clinic. The reduced psychiatric admission rate is an important potential benefit of ARMS clinics that requires replication.

Efficacy and Safety of Blonanserin Oral Tablet in Adolescents with Schizophrenia: A 6-Week, Randomized Placebo-Controlled Study

Objectives: To evaluate the short-term efficacy and safety of blonanserin in adolescents with schizophrenia. Methods: This 6-week multicenter, double-blind, randomized, placebo-controlled study investigated fixed-dose blonanserin (8 or 16 mg/day) in patients 12-18 years of age diagnosed with schizophrenia, as indicated by a Positive and Negative Syndrome Scale (PANSS) total score of 60-120 and a Clinical Global Impressions-Severity score of ≥3. The primary endpoint was change from baseline to week 6 in the PANSS total score, using a mixed model for repeated measures analysis. Safety was assessed by the incidence and severity of adverse events (AEs). Results: Among 151 randomized patients, 150 were included in the primary analysis population. Demographic and clinical characteristics were similar across groups at baseline. The rate of study discontinuation was 14.9%, 23.5%, and 28.3% in patients administered with placebo, blonanserin 8 mg/day, and blonanserin 16 mg/day, respectively. The least-squares mean change (95% confidence interval [CI]) from baseline to week 6 in PANSS total score was -10.6 (-16.10 to -5.10), -15.3 (-20.80 to -9.86), and -20.5 (-25.89 to -15.16) in patients administered placebo, 8 mg/day blonanserin, and 16 mg/day blonanserin, respectively. The 16-mg/day blonanserin group showed significantly greater reduction in the PANSS total score than the placebo group (least-squares mean difference [95% CI]: -9.9 [-17.61 to -2.25], p = 0.012, effect size: 0.538), although the 8-mg/day group showed no significant difference. The incidence of AEs such as akathisia, somnolence, and hyperprolactinemia was higher in the blonanserin groups than in the placebo group. AEs associated with blonanserin were generally mild and were consistent with its known profile in adults with schizophrenia. Conclusions: Blonanserin achieved a sufficient efficacy in adolescent patients, and the safety profile was similar to that in adults, which suggests that blonanserin may be a safe treatment option for adolescents with schizophrenia. Study registration number: Japic CTI-111724.

Affective lability and social functioning in severe mental disorders

Social functioning is impaired in severe mental disorders despite clinical remission, illustrating the need to identify other mechanisms that hinder psychosocial recovery. Affective lability is elevated and associated with an increased clinical burden in psychosis spectrum disorders. We aimed to investigate putative associations between affective lability and social functioning in 293 participants with severe mental disorders (schizophrenia- and bipolar spectrum), and if such an association was independent of well-established predictors of social impairments. The Affective Lability Scale (ALS-SF) was used to measure affective lability covering the dimensions of anxiety-depression, depression-elation and anger. The interpersonal domain of the Social Functioning Scale (SFS) was used to measure social functioning. Correlation analyses were conducted to investigate associations between affective lability and social functioning, followed by a hierarchical multiple regression and follow-up analyses in diagnostic subgroups. Features related to premorbid and clinical characteristics were entered as independent variables together with the ALS-SF scores. We found that higher scores on all ALS-SF subdimensions were significantly associated with lower social functioning (p < 0.005) in the total sample. For the anxiety-depression dimension of the ALS-SF, this association persisted after controlling for potential confounders such as premorbid social functioning, duration of untreated illness and current symptoms (p = 0.019). Our results indicate that elevated affective lability may have a negative impact on social functioning in severe mental disorders, which warrants further investigation. Clinically, it might be fruitful to target affective lability in severe mental disorders to improve psychosocial outcomes.

Preliminary evidence supporting the practice of psychosis-risk screening within an inpatient psychiatric setting serving adolescents

Evidence supports the use of brief psychosis-spectrum screening measures to identify individuals at elevated risk for psychosis, however, there is limited research on psychosis-spectrum screening among adolescents hospitalized for acute mental health concerns. Given the psychiatric vulnerability of this population, screening efforts within inpatient settings may help identify adolescents at greatest risk for ongoing mental health concerns including psychosis. This study investigates the use of two brief screening tools to identify psychosis-spectrum symptoms in psychiatrically hospitalized adolescents. Upon intake, adolescents completed two screening measures, the PRIME Screen-Revised and the Youth Self-Report Thought Problems scale, followed by a brief interview to evaluate psychosis-spectrum diagnoses. Associations between screening scores and diagnostic status were explored to evaluate the use of these tools to identify psychosis-spectrum conditions in this population. The sample included 57 adolescents, 28 of whom met psychosis-spectrum criteria. Psychosis-spectrum status was strongly correlated with PRIME scores (r = 0.59) and Thought Problems T scores (r = 0.55). Logistic regression analyses indicated that both screening measures demonstrate promising accuracy (74-81%) for identifying adolescents meeting psychosis-spectrum criteria. The PRIME and Thought Problems scale may be appropriate screening tools for use in adolescent inpatient settings to identify those experiencing clinically significant psychosis-spectrum symptoms.

Epigenetics and first-episode psychosis: A systematic review

BACKGROUND

Schizophrenia has a large disease burden globally. Early intervention in psychosis, and therefore a decreased duration of untreated psychosis, has a positive clinical impact. There are several recognized risk factors for psychosis, including trauma history and substance use. This systematic review examined the literature for studies related to epigenetic changes in first-episode psychosis, with the goal of identifying future research directions.

METHODS

A literature review was conducted from inception to October 3, 2021 using MedLine/PubMed, Web of Science, and PsycInfo searches with the keywords ("first-episode schizophrenia" OR "first-episode psychosis" OR "drug-naive schizophrenia" OR "drug-naive psychosis") AND (epigenetic OR methylation OR hydroxymethylation OR "histone modification" OR "miRNA") as well as a search of the bibliography of the identified papers.

RESULTS

Seventeen studies that examined various portions of the genome were included in this systematic review. There were two studies that showed hypomethylation at the LINE-1 portion of the genome and two that showed hypermethylation at LINE-1. Additionally, two studies showed hypomethylation specifically at the GRIN2B promoter (part of LINE-1).

CONCLUSIONS

Although sample sizes were small, these studies provide evidence for epigenetic alterations in early psychosis. Further research in this area is warranted for more definitive epigenetic correlations.

Reducing the Duration of Untreated Psychosis (DUP) in a US Community: A Quasi-Experimental Trial

Objective

Duration of Untreated Psychosis (DUP) remains unacceptably long and limits effectiveness of care. To determine whether an early detection campaign ("Mindmap") can reduce DUP in a US community setting.

Methods

In this nonrandomized controlled trial, Mindmap targeted the catchment of one specialty first-episode service or FES (STEP, Greater New Haven) from 2015 to 2019, while usual detection efforts continued at a control FES (PREP, Greater Boston). Mindmap targeted diverse sources of delay through mass & social media messaging, professional outreach & detailing, and rapid enrollment of referrals. Both FES recruited 16-35 years old with psychosis onset ≤3 years. Outcome measures included DUP-Total (onset of psychosis to FES enrollment), DUP-Demand (onset of psychosis to first antipsychotic medication), and DUP-Supply (first antipsychotic medication to FES enrollment).

Results

171 subjects were recruited at STEP and 75 at PREP. Mindmap was associated with an increase in the number of referrals and in efficiency of engagement at STEP. Pre-campaign DUP (2014-2015) was equivalent, while Mindmap was associated with DUP reductions at STEP but not PREP. DUP-Total fell significantly in both the first and the second quartile (11.5 and 58.5 days reduction per campaign year, respectively). DUP-Demand and DUP-Supply fell in the third quartiles only (46.3 and 70.3 days reduction per campaign year, respectively). No reductions were detectable across all quartiles at PREP, but between site comparisons were not significant.

Conclusions

This is the first controlled demonstration of community DUP reduction in the US, and can inform future early detection efforts across diverse settings.

Screening for Early Emerging Mental Experiences (SEE ME): A Model to Improve Early Detection of Psychosis in Integrated Primary Care

Early intervention in serious mental health conditions relies on the accurate identification of adolescents and young adults at high risk or with very recent onset of psychosis. Current early detection strategies have had limited success, identifying only a fraction of these individuals within the recommended 3- to 6-month window. Broader public health strategies such as population screening are hampered by low base rates and poor self-report screen specificity. Screening for Early Emerging Mental Experiences (SEE ME) is a three-stage "SCREEN-TRIAGE-ENGAGE" model for the early detection of psychosis in integrated primary care adolescent and young adult patients during the period of peak onset. It builds on the KNOW THE SIGNS-FIND THE WORDS-MAKE THE CONNECTION framework outlined on psychosisscreening.org and developed with input from community collaborators. Systematic screening aims to expand the reach of early detection and reduce reliance on provider knowledge. Triage and engagement by trained mental health clinicians aims to improve the specificity of screen responses, enhance engagement in appropriate care, and reduce provider burden. Leveraging the low stigma of primary care, its reach to non-help-seeking adolescents and young adults, and the mental health training of clinicians within integrated care practices, SEE ME has potential to improve the benefit/risk ratio of early detection of psychosis by improving both the sensitivity and specificity of screening and clinical response. We review the rationale and design of this promising model.

Psychosis-Spectrum Screening and Assessment Within a College Counseling Center: A Pilot Study Exploring Feasibility and Clinical Need

Evidence supports the use of brief psychosis-spectrum screening tools for identifying individuals at an increased risk of developing a psychotic disorder. Screening has not been well studied in general mental health settings that serve young adults in the age range associated with highest risk for psychosis. This study explored the feasibility of psychosis-risk screening and assessment among help-seeking students at a university counseling center. The PRIME Screen-Revised was administered to students at clinic intake. Participants who screened positively were offered a follow-up assessment using the Structured Interview for Psychosis-risk Syndromes (SIPS). At intake, 510 students completed the PRIME Screen-Revised, with 132 (25.9%) screening positive. Comprehensive psychosis-spectrum evaluations were completed with 38 participants, and 22 met criteria for a psychosis-spectrum disorder, representing 57.9% of this subsample. Findings suggest that psychosis-risk screening in a college clinic is a promising approach to identifying those at high risk for or in the early stages of psychosis.

The First Episode Rapid Early Intervention for Eating Disorders - Upscaled study: Clinical outcomes

BACKGROUND

First Episode Rapid Early Intervention for Eating Disorders (FREED) is a service model and care pathway for emerging adults aged 16 to 25-years with a recent onset eating disorder (ED) of <3 years. A previous single-site study suggests that FREED significantly improves clinical outcomes compared to treatment-as-usual (TAU). The present study (FREED-Up) assessed the scalability of FREED. A multi-centre quasi-experimental pre-post design was used, comparing patient outcomes before and after implementation of FREED in participating services.

METHODS

FREED patients (n = 278) were consecutive, prospectively ascertained referrals to four specialist ED services in England, assessed at four time points over 12 months on ED symptoms, mood, service utilization and cost. FREED patients were compared to a TAU cohort (n = 224) of similar patients, identified retrospectively from electronic patient records in participating services. All were emerging adults aged 16-25 experiencing a first episode ED of <3 years duration.

RESULTS

Overall, FREED patients made significant and rapid clinical improvements over time. 53.2% of FREED patients with anorexia nervosa reached a healthy weight at the 12-month timepoint, compared to only 17.9% of TAU patients (X2 [1, N = 107] = 10.46, p < .001). Significantly fewer FREED patients required intensive (i.e., in-patient or day-patient) treatment (6.6%) compared to TAU patients (12.4%) across the follow-up period (X2 [1, N = 40] = 4.36, p = .037). This contributed to a trend in cost savings in FREED compared to TAU (-£4472, p = .06, CI -£9168, £233).

DISCUSSION

FREED is robust and scalable and is associated with substantial improvements in clinical outcomes, reduction in inpatient or day-patient admissions, and cost-savings.

Patterns of Care for Adolescent With Schizophrenia: A Delphi-Based Consensus Study

BACKGROUND

The current conceptualization of schizophrenia as neurodevelopmental disorder should lead to innovative public health policies in terms of a reorganization of the mental health care systems, particularly in the transition from adolescence to adulthood, to reduce personal, familiar, and social costs and burdens. The purpose of the project was to perform a survey among a panel of Italian schizophrenia experts, to share evidence-based information on adolescent schizophrenia and explore the degree of consensus among professionals in the following four macro-areas: early diagnosis; pharmacological treatment; health care system organization and transition process from adolescent to adulthood; and psychosocial interventions.

METHODS

The consensus process consisted of a two-step web-based Delphi method, which took place between June and November 2021. The survey was developed by a panel of four psychiatrists and four child neuropsychiatrists, identified as key opinion leaders (KOLs). The KOLs identified 21 statements involving a total of 70 items with a major need of clarification on early-onset schizophrenia (EOS). The survey was distributed to 86 specialists in psychiatry and child neuropsychiatry.

RESULTS

The results revealed a large agreement among the expert group on all the investigated areas of adolescent schizophrenia patterns of care and management. Consensus was ultimately reached for 67 items of the Delphi survey (95.7%), while negative consensus was reached for 2 items and no consensus was reached for 1 item.

CONCLUSIONS

Overall, results showed a significant gap between the acquired scientific knowledge and clinical practice. In this scenario, it should be necessary to plan specific initiatives at a multiple level, to edit recommendations on clinical decision-making, as well as to prompt changes at the political and organizational levels, also involving scientific societies, patients, and family associations, to overcome the barriers that delay the implementation process.

Implementation of first episode psychosis intervention in India - A case study in a low-and middle-income country

First Episode Psychosis (FEP) is a serious mental illness affecting adolescents and young persons. While many effective interventions are available, there has not been much research to understand the implementation of such interventions in India and other low- and middle-income countries (LMIC). We studied the implementation of an FEP intervention program in a specialist mental health facility in Chennai, India, using a well-established framework for doing so, the Consolidated Framework for Implementation Research (CFIR). We conducted 27 in-depth interviews with the service users (15 persons with FEP and 12 family caregivers of persons with FEP). We also conducted a focus group discussion with 8 service providers and in-depth interviews with 7 other service providers including those in the service management. A thematic analysis approach was used to identify emerging themes. First, we found CFIR effectively accommodated implementation challenges evident in LMICs; that is, it is transferable to LMIC settings. Second, we highlight barriers to implementation that include cost, limited human resources, cultural and professional hierarchy, divergence from evidence-based guidelines, and lack of awareness and stigma in the wider community. Third, we highlight facilitators for implementation such as, leadership engagement, the need for change that was recognized within the service, cosmopolitan perspectives derived from clinicians’ local and international collaborative experiences and expertise, compatibility of the intervention with the existing systems within the organization, accommodating the needs of the service users, and rapport developed by the service with the service users. Fourth, we propose a model of service delivery incorporating a task-sharing approach for first episode psychosis in resource restricted settings based on the feedback from the stakeholders.

•

Implementation of interventions for First Episode Psychosis in India is explored systematically.

•

Resource constraints, cultural factors, lack of awareness, and stigma are the main barriers to the implementation.

•

Buy-in from the service providers, accommodating the needs and developing rapport with the service users are the facilitators.

Overcoming the gap between child and adult mental health services: The Reggio Emilia experience in an early intervention in psychosis program

AIM

Early intervention in psychosis (EIP) can reduce severity and persistence of illness. From September 2012, the Reggio Emilia Department of Mental Health developed the 'Reggio Emilia At-Risk Mental States' (ReARMS) protocol as a specific EIP infrastructure in all its adult and child/adolescent mental health services. Aims of this study were (a) to describe the ReARMS macroscopic organization and (b) to analyse some specific process indicators (i.e., the amount of individuals referred to the ReARMS program, the number of subjects who met defined diagnostic criteria of early psychosis and accepted the intervention, and the 1-year drop-out rate) during the first 5 years of its clinical activity, in order to examine feasibility and quality of its procedures on the adolescent help-seeking subgroup.

METHODS

Adolescent participants (n = 125), aged 13-18 years, completed the Comprehensive Assessment of At-Risk Mental States (CAARMS) to investigate the clinical status. Descriptive quantitative analyses were then used.

RESULTS

Fifty (40%) individuals did not meet early psychosis-defined criteria, while 75 (60%: i.e., 44 Ultra-High Risk [UHR] and 31 First Episode Psychosis [FEP] subjects) were offered an EIP dedicated care protocol: of them, 66 (88%) were enrolled in the program and 9 (12%) dropped out during the first year of treatment). Adolescents enrolled in the ReARMS protocol were mainly referred by general practitioners (32%), family members (16%), or school/social services (15.2%). Seventy (56%) participants had a history of previous specialist contact (especially for learning and anxiety disorders).

CONCLUSIONS

An EIP program for adolescents with early psychosis in Italian child/adolescent mental health services are feasible, clinically relevant and recommended, specifically in this age group with a high risk of falling through the child/adult service gap.

Comparison of clinical characteristics and treatment efficacy in childhood-onset schizophrenia and adolescent-onset schizophrenia in mainland China: A retrospective study

AIM

The comparative study of childhood-onset schizophrenia (COS) and adolescent-onset schizophrenia (AOS) is scarce. This study aimed to examine the differences in clinical presentations and treatment efficacy between COS and AOS and further analyse the factors affecting the efficacy of early-onset schizophrenia (EOS).

METHODS

A total of 582 electronic medical records of inpatients with EOS (216 COS and 366 AOS inpatients) between 2012 and 2019 were retrospectively analysed. The positive and negative syndrome scale (PANSS) was used to assess psychotic symptoms. Logistic regression analysis was performed to analyse the predictors of efficacy.

RESULTS

The mean age of onset of EOS was 12.87 ± 2.19 years. The importance of better diagnosing COS appeared in a longer illness course, more frequently insidious onset, less frequent delusions, more severe negative symptoms and bizarre behaviours than AOS. Besides, COS had more frequent visual hallucinations and impulsive behaviours than AOS. After hospitalization, the improvement rate of psychotic symptoms in COS and AOS were 38.3% and 47.8%, respectively. The difference of efficacy between the two groups was statistically significant. Days of hospitalization, age of onset, presence of flat affect, PANSS total and negative score at admission were predictors of treatment efficacy in EOS individuals.

CONCLUSIONS

COS inpatients suffer more obvious negative symptoms, bizarre behaviours, visual hallucinations and impulsive behaviours and worse efficacy than AOS inpatients. The severity of negative symptoms and age of onset seem the most noteworthy predictors of efficacy. These findings highlight the importance of early detection and early intervention.

Duration of Untreated Disorder and Cannabis Use: An Observational Study on a Cohort of Young Italian Patients Experiencing Psychotic Experiences and Dissociative Symptoms

BACKGROUND

The Duration of Untreated Psychosis (DUP) is the time between the first-episode psychosis (FEP) and the initiation of antipsychotic treatment. It is an important predictor of several disease-related outcomes in psychotic disorders. The aim of this manuscript is investigating the influence of cannabis on the DUP and its clinical correlates.

METHODS

During years 2014-2019, sixty-two FEP patients with and without cannabis use disorder (CUD) were recruited from several Italian psychiatric hospitals. The subjects were then divided into two groups based on the duration of the DUP and assessed at the beginning of the antipsychotic treatment and after 3 and 6 months, using the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF) scale, and the Dissociative Experiences Scale (DES-II).

RESULTS

As expected, a longer DUP was associated with worse symptoms and cannabis use did not seem to affect the DUP, but both were related with more dissociative symptoms at onset and over time.

DISCUSSION

According to our study, cannabis use can be a predictor of FEP and DUP, and of disease outcome. However, several factors might influence the relationship between cannabis use and DUP. Preventing cannabis use and early diagnosis of psychotic disorders might impact the disease by reducing the persistence of symptoms and limiting dissociative experiences.

Polygenic risk scores across the extended psychosis spectrum

As early detection of symptoms in the subclinical to clinical psychosis spectrum may improve health outcomes, knowing the probabilistic susceptibility of developing a disorder could guide mitigation measures and clinical intervention. In this context, polygenic risk scores (PRSs) quantifying the additive effects of multiple common genetic variants hold the potential to predict complex diseases and index severity gradients. PRSs for schizophrenia (SZ) and bipolar disorder (BD) were computed using Bayesian regression and continuous shrinkage priors based on the latest SZ and BD genome-wide association studies (Psychiatric Genomics Consortium, third release). Eight well-phenotyped groups (n = 1580; 56% males) were assessed: control (n = 305), lower (n = 117) and higher (n = 113) schizotypy (both groups of healthy individuals), at-risk for psychosis (n = 120), BD type-I (n = 359), BD type-II (n = 96), schizoaffective disorder (n = 86), and SZ groups (n = 384). PRS differences were investigated for binary traits and the quantitative Positive and Negative Syndrome Scale. Both BD-PRS and SZ-PRS significantly differentiated controls from at-risk and clinical groups (Nagelkerke's pseudo-R2: 1.3-7.7%), except for BD type-II for SZ-PRS. Out of 28 pairwise comparisons for SZ-PRS and BD-PRS, 9 and 12, respectively, reached the Bonferroni-corrected significance. BD-PRS differed between control and at-risk groups, but not between at-risk and BD type-I groups. There was no difference between controls and schizotypy. SZ-PRSs, but not BD-PRSs, were positively associated with transdiagnostic symptomology. Overall, PRSs support the continuum model across the psychosis spectrum at the genomic level with possible irregularities for schizotypy. The at-risk state demands heightened clinical attention and research addressing symptom course specifiers. Continued efforts are needed to refine the diagnostic and prognostic accuracy of PRSs in mental healthcare.

Proportion and predictors of remission and recovery in first-episode psychosis: Systematic review and meta-analysis

Background

To determine the proportion of patients in symptomatic remission and recovery following a first-episode of psychosis (FEP).

Methods

A multistep literature search using the Web of Science database, Cochrane Central Register of Reviews, Ovid/PsychINFO, and trial registries from database inception to November 5, 2020, was performed. Cohort studies and randomized control trials (RCT) investigating the proportion of remission and recovery following a FEP were included. Two independent researchers searched, following PRISMA and MOOSE guidelines and using a PROSPERO protocol. We performed meta-analyses regarding the proportion of remission/recovery (symptomatic plus functional outcomes). Heterogeneity was measured employing Q statistics and I² test. To identify potential predictors, meta-regression analyses were conducted, as well as qualitative reporting of studies included in a systematic review. Sensitivity analyses were performed regarding different times of follow-up and type of studies.

Results

One hundred articles (82 cohorts and 18 RCTs) were included in the meta-analysis. The pooled proportion of symptomatic remission was 54% (95%CI [30, 49–58]) over a mean follow-up period of 43.57 months (SD = 51.82) in 76 studies. After excluding RCT from the sample, the proportion of remission remained similar (55%). The pooled proportion of recovery was 32% (95%CI [27–36]) over a mean follow-up period of 71.85 months (SD = 73.54) in 40 studies. After excluding RCT from the sample, the recovery proportion remained the same. No significant effect of any sociodemographic or clinical predictor was found.

Conclusions

Half of the patients are in symptomatic remission around 4 years after the FEP, while about a third show recovery after 5.5 years.

Mapping the steps to reach psychiatric care in Singapore: An examination of services utilized and reasons for seeking help

OBJECTIVE

The aim of this study is to shed light on the types of services utilized and map the steps taken by patients in their pathways to receiving psychiatric care in Singapore.

METHODS

Participants were outpatients who were recruited from a psychiatric tertiary hospital (n = 323). Pathways to psychiatric care form was administered to collect information on sources of care utilized, reasons for seeking help and the time point of each contact made. Pathways taken by patients to reach psychiatric care were mapped, and reasons for seeking help were reviewed and analyzed. Quantile regression was conducted to explore association between sociodemographic and clinical factors with duration between onset of problem and receiving psychiatric care.

RESULTS

The need to manage symptoms was most commonly endorsed by participants as the reason that first prompted them to seek help. Prior to receiving psychiatric care, participants on average obtained services from 1.2 other care providers and the main pathway to psychiatric services was via primary care and community services (37.2%). The median duration between onset of problem and receiving psychiatric care was 6 months, and age was found to be significantly associated with shorter median duration (β = -0.172, p = 0.009).

CONCLUSIONS

Patients often consult different care providers prior to obtaining psychiatric services and contact was made more frequently via primary care and community care providers. Findings from this study reiterate the need for engaging community partners to render timely and relevant support for individuals with mental health issues.

An exploratory evaluation of predictors of duration of untreated psychosis in first-episode psychosis in lower income patients

A longer duration of untreated psychosis (DUP) may adversely affect the course and impact of the illness. Little is known about predictors of duration of untreated psychosis in lower socioeconomic strata (SES) in urban India. We examined variables associated with DUP in 60 urban lower SES patients diagnosed with first-episode, untreated psychosis. Instruments used included the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF), the UCLA Social Attainment Scale (SAS), and the Stigma Subscale from the Family Interview Schedule. The mean age of the sample was 30.5 years. The sample was 50% male. Most patients (90%) were living in a nuclear family. The median DUP was 120 days. DUP was <6 months in 31.7% of the sample and >2 years in 23.3%. A third of the sample had been taken to faith healers before being brought into medical care. DUP was not significantly associated with age, sex, religion, education, family history of mental illness, marital status, employment status, income, substance use, PANSS subscale and total scale scores, and GAF scores. Presence of an antecedent stressor, acute onset of psychosis, presence of medical co-morbidities, lower stigma scores, and higher SAS scores were significantly associated with shorter DUP.

Basic symptoms and gray matter volumes of patients at clinical high risk for psychosis

BACKGROUND

Clinical high-risk (CHR) for psychosis is indicated by ultra-high risk (UHR) and basic symptom (BS) criteria; however, conversion rates are highest when both UHR and BS criteria are fulfilled (UHR&BS). While BSs are considered the most immediate expression of neurobiological aberrations underlying the development of psychosis, research on neurobiological correlates of BS is scarce.

METHODS

We investigated gray matter volumes (GMV) of 20 regions of interest (ROI) previously associated with UHR criteria in 90 patients from the Bern early detection service: clinical controls (CC), first-episode psychosis (FEP), UHR, BS and UHR&BS. We expected lowest GMV in FEP and UHR&BS, and highest volume in CC with UHR and BS in-between.

RESULTS

Significantly, lower GMV was detected in FEP and UHR&BS patients relative to CC with no other significant between-group differences. When ROIs were analyzed separately, seven showed a significant group effect (FDR corrected), with five (inferior parietal, medial orbitofrontal, lateral occipital, middle temporal, precuneus) showing significantly lower GM volume in the FEP and/or UHR&BS groups than in the CC group (Bonferroni corrected). In the CHR group, only COGDIS scores correlated negatively with cortical volumes.

CONCLUSIONS

This is the first study to demonstrate that patients who fulfill both UHR and BS criteria - a population that has been associated with higher conversion rates - exhibit more severe GMV reductions relative to those who satisfy BS or UHR criteria alone. This result was mediated by the BS in the UHR&BS group, as only the severity of BS was linked to GMV reductions.

Facilitating treatment engagement for early psychosis through peer-delivered decision support: intervention development and protocol for pilot evaluation

BACKGROUND

Emerging adults with early psychosis demonstrate high rates of service disengagement from critical early intervention services. Decision support interventions and peer support have both been shown to enhance service engagement but are understudied in this population. The purposes of this article are to describe the development of a novel peer-delivered decision coaching intervention for this population and to report plans for a pilot study designed to gather preliminary data about its feasibility, acceptability, and potential impact.

METHODS

The intervention was developed based on formative qualitative data and in collaboration with a diverse team of researchers, key stakeholders, and expert consultants. The pilot trial will utilize a single-group (N = 20), pre-post, convergent mixed-methods design to explore whether and how the intervention addresses decision-making needs (the primary intervention target). The impact of the intervention on secondary outcomes (e.g., engagement in the program) will also be assessed. Additionally, through observation and feedback from the peer decision coach and study participants, we will evaluate the feasibility of research and intervention procedures, and the acceptability of information and support from the peer decision coach.

DISCUSSION

The peer-delivered decision coaching intervention holds promise for assisting young people with making informed and values-consistent decisions about their care, and potentially enhancing service engagement within this traditionally difficult-to-engage population. If the intervention demonstrates feasibility and acceptability, and pilot data show its potential for improving treatment decision-making, our work will also lay the foundation for a new evidence base regarding roles for peer specialists on early intervention teams.

Machine learning for brain age prediction: Introduction to methods and clinical applications

The rise of machine learning has unlocked new ways of analysing structural neuroimaging data, including brain age prediction. In this state-of-the-art review, we provide an introduction to the methods and potential clinical applications of brain age prediction. Studies on brain age typically involve the creation of a regression machine learning model of age-related neuroanatomical changes in healthy people. This model is then applied to new subjects to predict their brain age. The difference between predicted brain age and chronological age in a given individual is known as ‘brain-age gap’. This value is thought to reflect neuroanatomical abnormalities and may be a marker of overall brain health. It may aid early detection of brain-based disorders and support differential diagnosis, prognosis, and treatment choices. These applications could lead to more timely and more targeted interventions in age-related disorders.

Implementation of NAVIGATE for first episode psychosis in Israel: Clients' characteristics, program utilization and ratings of change

OBJECTIVE

NAVIGATE is a comprehensive treatment program for first episode psychosis developed and implemented in the US that has been found to be effective. The purpose of the present study was to describe the first initiative of NAVIGATE's implementation outside the US, and to present data collected in Israel from the first two clinics focusing on NAVIGATE clients' characteristics, components utilization and retrospective clinician ratings of change.

METHODS

Administrative data for 61 NAVIGATE clients in Israel and retrospective ratings of NAVIGATE clinicians were analysed.

RESULTS

The duration of untreated psychosis was 4.4 months (SD = 6.8). Clients were mostly referred to NAVIGATE from psychiatric hospitals (n = 29, 50.9%) and community mental health agencies (n = 20, 35.1%). The individualized resiliency training (IRT) component had the highest client utilization rate (n = 53, 98.1%) with a monthly average of M = 2.32 sessions (SD = 2.75). Clinicians' retrospective ratings indicated that 66% of the clients (n = 33) had improved in at least one life domain, with the most common improvement in employment (n = 28, 56%), recovery (n = 24, 50%), and symptoms severity (n = 23, 47%).

CONCLUSIONS

Our findings reveal that NAVIGATE can be implemented outside the US within a different social and cultural context and different mental health system. The utilization rates of the program components and clinicians' retrospective ratings indicated positive change among most of NAVIGATE clients, pointing to the potential value of NAVIGATE above and beyond different countries and health systems.

Pathways to care in at-risk mental states: A systematic review

AIM

Pathways to care are well studied in the First Episode Psychosis field, but less attention has been given to At-Risk Mental States or prodromal psychosis. This is important because accessing appropriate help at the earliest opportunity is likely to improve outcomes, particularly for those who make transition to psychosis. The present systematic review aimed to synthesize the available literature on pathways to care in ARMS or prodromal psychosis, and investigate the barriers and facilitators to receiving care for ARMS.

METHODS

The CINAHL Complete, EMBASE, Medline Complete, PsycINFO and PubMED databases were searched. Studies were included if they were published in English between 1985 and 2019, where reported data came exclusively from an At-Risk Mental State population, and the study described or related to pathways to care.

RESULTS

Ten studies met the inclusion criteria, of which 8 were quantitative. Screening tools and pathways to care instruments varied. Mental health professionals, and general practitioners played a key role in help seeking. Family involvement was also found to be an important factor.

CONCLUSIONS

Pathways to care research in At-Risk Mental States are more scarce than in the field of First Episode Psychosis. More research is warranted, especially concerning the role of patient-level characteristics on pathways to care. A validated measure of pathways to care may also be of benefit.

Factors associated with overall functioning in patients with schizophrenia in a general hospital in Peru

OBJECTIVE

To evaluate the influence of the factors associated with overall functioning in patients with schizophrenia who attended the outpatient clinic of the Hospital Nacional de la Policía [National Police Hospital] "Luis Nicasio Saenz" in 2018-2019.

METHODOLOGY

Non-experimental quantitative study of a descriptive cross-sectional correlational type. Convenience sampling was carried out, and consisted of 53 patients with schizophrenia. Functioning Assessment Short Test (FAST) was used to assess overall functioning, the Screen for Cognitive Impairment in Psychiatry (SCIP) for cognitive functioning, and a data collection sheet with sociodemographic data and a history of the disease.

RESULTS

It was found that 34 (62.2%) patients were male; 52 (98.1%), single; 39, (73.6%) without a current job. We found worse overall functioning in patients with a lower educational level (P = .005) and without a current job (P = .004). The total FAST was correlated with the time of the disease (ρ = 0.334, P < .05), the number of previous psychotic episodes (ρ = 0.354, P < .01), the total SCIP score (ρ = 0.542, P < .01) and their working memory dimension (VMT) (ρ = -0.523, P < .05). In the multiple linear regression model, it was found that the variables that most influenced the FAST were the total SCIP score (Beta = -0.528) and the number of previous psychotic episodes (Beta = 0.278).

CONCLUSION

The associated factors that most influence overall functioning in this sample of Peruvian patients with schizophrenia are cognitive functioning and the number of previous psychotic episodes.

The Impact of Repeated Attachment Priming on Paranoia, Mood and Help-Seeking Intentions in an Analogue Sample

Attachment security priming effects therapeutic change in people with depression and anxiety. Preliminary studies indicate that visualising secure attachment memories also reduces paranoia in non-clinical and clinical groups, probably due to a decrease in cognitive fusion. Benefits to clinical populations depend on the sustainability of these effects and the impact on help-seeking behaviours. The combination of paranoia and an insecure-avoidant attachment style is likely to be a particular barrier to help seeking. We used a longitudinal experimental design to test the impact of repeated attachment priming on paranoia, mood and help-seeking intentions and whether cognitive fusion mediates these effects. Seventy-nine people with high levels of non-clinical paranoia, aged 18-50 years (M = 20.53, SD = 4.57), were randomly assigned to a secure or insecure-avoidant priming condition. Participants rehearsed the visualisation prime on four consecutive days and were assessed on standardised measures of paranoia, positive and negative affect, help-seeking intentions and cognitive fusion. A series of mixed-model analyses of variance showed that security priming decreases paranoia, negative affect and cognitive fusion and increases positive affect and help seeking, compared to insecure-avoidant priming. Examining the impact of primed attachment (rather than measured attachment style) allows us to draw conclusions about the causal processes involved; mediation analyses showed indirect effects of the primes on paranoia and negative affect through cognitive fusion. With a growing understanding of (1) the impact of security priming on paranoia, affect and help-seeking behaviours, (2) causal mechanisms and (3) sustainability of effects, security priming may be developed into a viable intervention for clinical populations.

Long Acting Injectable Antipsychotics in the Treatment of Schizophrenia and Bipolar Disorder

Schizophrenia and bipolar disorder (BD) are psychiatric disorders with economic and social effects that cause disability. Treatment non-compliance is one of the major problems faced by clinicians in both schizophrenia and BD. Treatment non-compliance is associated with recurrence and impaired functionality. Treatment compliance increases with long-acting injectable antipsychotics (LAIAs) and recurrence times are prolonged, hospitalization rates decrease compared to those who use an equivalent oral form of the same drug. The use of LAIAs in the maintenance treatment of schizophrenia has also been associated with a low mortality rate, decrease in caregiver burden, and increase in patient satisfaction. Studies show that LAIAs are cost-effective compared to their oral forms. Data on the use of LAIAs in first-episode schizophrenia and BD are relatively limited. The results of studies on the use of LAIAs in patients with first-episode schizophrenia indicate that LAIAs have advantageous in preventing relapse and re-hospitalization compared to oral antipsychotics. In BD, with the use of LAIAs, the rate of hospitalization due to mood episodes and the frequency of manic episodes have been decreased. LAIAs have not been found to be as effective in preventing depressive episodes in BD as manic episodes. Although there are many studies supporting the use of LAIAs in maintenance treatment of schizophrenia and BD, more studies are needed on this issue. In this article, studies on the use of LAIAs in schizophrenia, first episode schizophrenia and BD are reviewed and the place of LAIAs in treatment was discussed.

Prediction of Early Symptom Remission in Two Independent Samples of First-Episode Psychosis Patients Using Machine Learning

BACKGROUND

Validated clinical prediction models of short-term remission in psychosis are lacking. Our aim was to develop a clinical prediction model aimed at predicting 4-6-week remission following a first episode of psychosis.

METHOD

Baseline clinical data from the Athens First Episode Research Study was used to develop a Support Vector Machine prediction model of 4-week symptom remission in first-episode psychosis patients using repeated nested cross-validation. This model was further tested to predict 6-week remission in a sample of two independent, consecutive Danish first-episode cohorts.

RESULTS

Of the 179 participants in Athens, 120 were male with an average age of 25.8 years and average duration of untreated psychosis of 32.8 weeks. 62.9% were antipsychotic-naïve. Fifty-seven percent attained remission after 4 weeks. In the Danish cohort, 31% attained remission. Eleven clinical scale items were selected in the Athens 4-week remission cohort. These included the Duration of Untreated Psychosis, Personal and Social Performance Scale, Global Assessment of Functioning and eight items from the Positive and Negative Syndrome Scale. This model significantly predicted 4-week remission status (area under the receiver operator characteristic curve (ROC-AUC) = 71.45, P < .0001). It also predicted 6-week remission status in the Danish cohort (ROC-AUC = 67.74, P < .0001), demonstrating reliability.

CONCLUSIONS

Using items from common and validated clinical scales, our model significantly predicted early remission in patients with first-episode psychosis. Although replicated in an independent cohort, forward testing between machine learning models and clinicians' assessment should be undertaken to evaluate the possible utility as a routine clinical tool.

PLAN-e-PSY, a mobile application to improve case management and patient's functioning in first episode psychosis: protocol for an open-label, multicentre, superiority, randomised controlled trial

INTRODUCTION

The prognosis of first episode psychosis (FEP), which is a severe disorder, can be notably impaired by patients' disengagement from healthcare providers. Coordinated specialty care with case management is now considered as the gold standard in this population, but there are still challenges for engagement with subsequent functional impairments. Youth-friendly and patient-centred clinical approaches are sought to improve engagement in patients with FEP. Mobile applications are widely used by young people, including patients with FEP, and can increase the youth friendliness of clinical tools. We hypothesise that a co-designed mobile application used during case management can improve functioning in patients with FEP as compared with usual case management practices.

METHODS AND ANALYSIS

A mobile case management application for planning and monitoring individualised care objectives will be co-designed with patients, caregivers and health professionals in a recovery-oriented approach. The application will be compared with usual case management practices in a multicentre, two-arm and parallel groups clinical trial. Patients will be recruited by specialised FEP teams. Impact on functioning will be assessed using the Personal and Social Performance Scale; the variation between baseline and 12 months in each group (control and active) will be the primary outcome.

ETHICS AND DISSEMINATION

This study has been approved by the Inserm Institutional Review Board IRB00003888 (Comité d'évaluation éthique de l'INSERM, reference number 20-647). The results of the study will be published in a peer-reviewed journal and presented at national and international conferences. We will also communicate the results to patients and family representatives' associations. An optimised version of the application will be then disseminated through the French FEP network (Transition Network).

Predictors of clozapine discontinuation at 2 years in treatment-resistant schizophrenia

INTRODUCTION

Little is known about predictors of clinical response to clozapine treatment in treatment-resistant psychosis. Most published cohorts are small, providing inconsistent results. We aimed to identify baseline clinical predictors of future clinical response in patients who initiate clozapine treatment, mainly focusing on the effect of age, duration of illness, baseline clinical symptoms and homelessness.

METHODOLOGY

Retrospective cohort of patients with treatment-resistant schizophrenia, aged between 15 and 60 years, that initiated clozapine between 2014 and 2017. Sociodemographic characteristics, years from illness diagnosis, and clinical presentation before the initiation of clozapine were collected and analyzed. All-cause discontinuation at two years follow-up was used as the primary measure of clozapine response.

RESULTS

261 patients were included with a median age at illness diagnosis of 23 years old (IQR 19-29) and a median age at clozapine initiation of 25 (IQR: 21-33). 72.33% (183/253) continued clozapine after two years follow-up. Being homeless was associated to higher clozapine non-adherence, with an OR of 2.78 (95%CI 1.051-7.38) (p = 0.039, controlled by gender). Older age at clozapine initiation and longer delay from first schizophrenia diagnosis to clozapine initiation were also associated with higher clozapine non-adherence, with each year increasing the odds of discontinuation by 1.043 (95%CI 1.02-1.07; p = 0.001) and OR 1.092 (95%CI 1.01-1.18;p = 0.032) respectively.

CONCLUSION

Starting clozapine in younger patients or shortly after schizophrenia diagnosis were associated with better adherence.

Early magnetic resonance imaging biomarkers of schizophrenia spectrum disorders: Toward a fetal imaging perspective

There is mounting evidence to implicate the intrauterine environment as the initial pathogenic stage for neuropsychiatric disease. Recent developments in magnetic resonance imaging technology are making a multimodal analysis of the fetal central nervous system a reality, allowing analysis of structural and functional parameters. Exposures to a range of pertinent risk factors whether preconception or in utero can now be indexed using imaging techniques within the fetus' physiological environment. This approach may determine the first "hit" required for diseases that do not become clinically manifest until adulthood, and which only have subtle clinical markers during childhood and adolescence. A robust characterization of a "multi-hit" hypothesis may necessitate a longitudinal birth cohort; within this investigative paradigm, the full range of genetic and environmental risk factors can be assessed for their impact on the early developing brain. This will lay the foundation for the identification of novel biomarkers and the ability to devise methods for early risk stratification and disease prevention. However, these early markers must be followed over time: first, to account for neural plasticity, and second, to assess the effects of postnatal exposures that continue to drive the individual toward disease. We explore these issues using the schizophrenia spectrum disorders as an illustrative paradigm. However, given the potential richness of fetal magnetic resonance imaging, and the likely overlap of biomarkers, these concepts may extend to a range of neuropsychiatric conditions.

The effects of patient personality traits and family cohesion on the treatment delay for patients with first-episode schizophrenia spectrum disorder

AIM

The duration of untreated psychosis (DUP) is an important prognostic indicator of schizophrenia. We explored the effects of patient personality and family relationships on delayed schizophrenia treatment.

METHODS

We prospectively included data from 169 patients diagnosed with first-episode schizophrenia. Personality traits were investigated using the Big Five Inventory (BFI-10) and family relationship was assessed employing the Family Adaptability and Cohesion Evaluation Scale-III (FACES-III). We explored patient clinical characteristics using the Positive and Negative Syndrome Scale (PANSS) and the Social and Occupational Functioning Scale (SOFAS). The DUP was defined as the time between the first appearance of psychotic symptoms and commencement of adequate antipsychotic treatment. Subjects were divided into two groups by the 3-month median DUP cutoff.

RESULTS

The average and median DUPs were 12 and 3 months, respectively. A longer DUP was associated with older age, a higher PANSS score, and a lower SOFAS score. The frequency of suicide attempts tended to be higher in the delayed treatment group (P = .055). The delayed treatment group scored significantly higher in conscientiousness factor of the BFI-10 and scored significantly lower family cohesion and adaptability factors of the FACES-III. Logistic regression showed that a longer DUP was significantly associated with higher-level conscientiousness on the BFI-10 and poorer family cohesion on the FACES-III.

CONCLUSION

Treatment delay was associated with reduced family cohesion and higher patient conscientiousness, suggesting that the family plays a crucial role in terms of patient access to mental health services when early psychotic symptoms appear.

First help-seeking attempt before and after psychosis onset: measures of delay and aversive pathways to care

PURPOSE

Delay in receiving effective treatment for psychosis adversely impacts outcomes. We investigated the timing of the first help-seeking attempt in individuals with recent onset non-affective psychosis by comparing those who sought help during the prodrome to those who sought help after psychosis onset across sociodemographic and clinical characteristics, overall functioning, and occurrence of aversive events during their pathways to care.

METHODS

Patients were admitted from February 1st, 2014 to January 31st, 2019 to the Program for Specialized Treatment Early in Psychosis (STEP) in New Haven, CT. Psychosis-onset date was ascertained using the Structured Interview for Psychosis-risk Syndromes. Key dates before and after psychosis onset, along with initiators and aversive events, were collected via semi-structured interview.

RESULTS

Within 168 individuals, 82% had their first help-seeking episode after psychosis onset and did not differ in terms of sociodemographic characteristics from prodrome help seekers. When the first help-seeking episode started before (i.e., during prodrome) vs after psychosis onset it was mostly initiated by patients vs family members (Cramer's V = 0.23, p = 0.031) and led to a faster prescription of an antipsychotic once full-blown psychosis emerged (time to antipsychotic since psychosis onset = 21 vs 56 days, p = 0.03). No difference in aversive events before STEP enrollment was detected across groups.

CONCLUSION

Help seeking during the prodrome is associated with faster initiation of antipsychotic treatment and is more likely to be self-initiated, compared to help seeking after psychosis onset. Early detection efforts that target prodromal samples may improve the length and experience of pathways to care.

Psychotic-like experiences among 9,564 Kenyan adolescents and young adults

OBJECTIVE

To investigate the prevalence and characteristics of psychotic-like experiences (PLE) in a large cohort of Kenyan adolescents and young adults.

METHOD

The Washington Early Recognition Center Affectivity and Psychosis (WERCAP) Screen was used to the study the 12-month prevalence of PLE's among 9,564 Kenyan youths (aged 15-25 yrs), and the rates of psychosis high-risk (HR) and medium-risk (MR) cases, based on cut-off scores. Relationships with clinical, demographic and economic profiles were investigated.

RESULTS

Across all participants, 72% reported having had at least one PLE over the last year. 4.6% and 30.6% were HR and MR based on symptom scores. There were similar PLE rates in females and males. PLE severity correlated with mood (r=0.67), stress (r=0.46), and autistic traits (r=0.18). PLE severity was also related to poverty, lower education attainment, and underemployment. Compared to controls, HR and MR youths were more likely to report lifetime substance use and to have more significant use.

CONCLUSION

Psychosis screening can provide valuable information about individuals and may help identify those who may require clinical assessment and intervention to improve outcomes. This is particularly relevant in many parts of Africa where the resources are limited for treating more advanced illness.

An fMRI study of cognitive remediation in drug-naïve subjects diagnosed with first episode schizophrenia

Objective

The purpose of our functional magnetic resonance imaging (fMRI) study was to examine brain activity using a “1-back” paradigm as working memory task in drug-naïve subjects with first episode schizophrenia before and after cognitive remediation training.

Methods

In this study 15 drug-naïve first episode subjects who met DSM-IV criteria for schizophrenia were randomized to receive either atypical antipsychotics (AP, n = 8) or atypical antipsychotics in combination with cognitive remediation therapy (AP + CR, n = 7), 11 subjects had a follow-up fMRI examination after therapy (AP, n = 5; AP + CR, n = 6).

Results

In 4 of the 6 AP + CR subjects the number of activation clusters increased, whereas in 4 out of the 5 AP subjects the number of clusters decreased (mean number of clusters: AP + CR = 5.53, SD 12.79, AP = −5.8, SD 6.9).

Conclusion

In this randomized study the number of activation clusters during a working memory task increased after cognitive remediation training. Our data show that neurobiological effects of cognitive remediation can be identified in the very early course of schizophrenia.

The use of first-generation long-acting injectable antipsychotics in children and adolescents-A retrospective audit from India

OBJECTIVES

There is a dearth of knowledge regarding the usage of first-generation long-acting injectable (LAI) antipsychotics in children and adolescents, despite their off-label use, in low and middle-income countries (LAMIC).

METHODS

Case records of subjects less than 18 years of age who received any first-generation LAI antipsychotics in the last 10 years(between 2010-19) were reviewed. Details documented for the study from the records included ICD-10 diagnoses, clinical profile, indication for use, medication details, severity of illness, improvement, and global functioning.

RESULTS

Forty-five subjects (55.3 % male) received first-generation LAI antipsychotics during the study period. All subjects were diagnosed to have serious mental illnesses, with Schizophrenia (52.6 %) and Bipolar Affective Disorder (31.6 %) being the most common diagnoses. At baseline, according to Clinical Global Impressions-Severity (CGI-S) scale, a majority (94.7 %) were severely or markedly ill. Fluphenazine decanoate (60.5 %), flupenthixol decanoate (34.2 %), and zuclopenthixol decanoate (18.4 %) were the first- generation LAI antipsychotics used. Nearly half the subjects (47.4 %) experienced at least one acute adverse event. The most common acute adverse events noted included tremors, rigidity, sialorrhea, and bradykinesia. 31/34 subjects showed improvement at follow-up.

CONCLUSIONS

The profile of patients for whom first-generation LAI antipsychotics were used included children and adolescents who had severe mental illnesses and were considerably ill. Acute adverse events were common. Short and- long-term follow-up studies are needed to evaluate the efficacy and safety of first-generation LAI antipsychotics in children and adolescents, especially in low and middle-income countries, given that they are reasonably priced and efficacious for severe mental illnesses.

Strucutural brain imaging at the onset of schizophrenia:What have we learned and what have we missed

Over the past 50 years, the application of structural neuroimaging techniques to schizophrenia research has added relevant information about the pathophysiology of the disorder. Several lines of investigation gave strong evidence that schizophrenia is associated with multiple subtle brain abnormalities that involve both cerebral grey and white matter volumes and structure. The time of onset and longitudinal course of brain morphological abnormalities support the notion that brain pathology of schizophrenia has a neurodevelopmental component and a progressive course, although several confounders of brain changes should be carefully taken into account. Brain anomalies detected before and close to the onset of schizophrenia are likely to be unrelated to confounders of brain changes such as antipsychotic drug treatment, duration of illness or illicit substance abuse, i.e. they related to the pathological process of the disorder per se. Nonetheless, clinically useful diagnostic or prognostic biomarkers have not derived from neuroimaging studies and this is likely related to the neurobiological heterogeneity of the disorder. Thus, there is the compelling need to set new methodological standards for developing innovative hypothesis-driven studies to overcome what we have missed to date in neuroimaging research in schizophrenia.

Computerized Assessment of Psychosis Risk

Early detection and intervention with young people at clinical high risk (CHR) for psychosis is critical for prevention efforts focused on altering the trajectory of psychosis. Early CHR research largely focused on validating clinical interviews for detecting at-risk individuals; however, this approach has limitations related to: (1) specificity (i.e., only 20% of CHR individuals convert to psychosis) and (2) the expertise and training needed to administer these interviews is limited. The purpose of our study is to develop the computerized assessment of psychosis risk (CAPR) battery, consisting of behavioral tasks that require minimal training to administer, can be administered online, and are tied to the neurobiological systems and computational mechanisms implicated in psychosis. The aims of our study are as follows: (1A) to develop a psychosis-risk calculator through the application of machine learning (ML) methods to the measures from the CAPR battery, (1B) evaluate group differences on the risk calculator score and test the hypothesis that the risk calculator score of the CHR group will differ from help-seeking and healthy controls, (1C) evaluate how baseline CAPR battery performance relates to symptomatic outcome two years later (i.e., conversion and symptomatic worsening). These aims will be explored in 500 CHR participants, 500 help-seeking individuals, and 500 healthy controls across the study sites. This project will provide a next-generation CHR battery, tied to illness mechanisms and powered by cutting-edge computational methods that can be used to facilitate the earliest possible detection of psychosis risk.

Classification of first-episode psychosis using cortical thickness: A large multicenter MRI study

Machine learning classifications of first-episode psychosis (FEP) using neuroimaging have predominantly analyzed brain volumes. Some studies examined cortical thickness, but most of them have used parcellation approaches with data from single sites, which limits claims of generalizability. To address these limitations, we conducted a large-scale, multi-site analysis of cortical thickness comparing parcellations and vertex-wise approaches. By leveraging the multi-site nature of the study, we further investigated how different demographical and site-dependent variables affected predictions. Finally, we assessed relationships between predictions and clinical variables. 428 subjects (147 females, mean age 27.14) with FEP and 448 (230 females, mean age 27.06) healthy controls were enrolled in 8 centers by the ClassiFEP group. All subjects underwent a structural MRI and were clinically assessed. Cortical thickness parcellation (68 areas) and full cortical maps (20,484 vertices) were extracted. Linear Support Vector Machine was used for classification within a repeated nested cross-validation framework. Vertex-wise thickness maps outperformed parcellation-based methods with a balanced accuracy of 66.2% and an Area Under the Curve of 72%. By stratifying our sample for MRI scanner, we increased generalizability across sites. Temporal brain areas resulted as the most influential in the classification. The predictive decision scores significantly correlated with age at onset, duration of treatment, and positive symptoms. In conclusion, although far from the threshold of clinical relevance, temporal cortical thickness proved to classify between FEP subjects and healthy individuals. The assessment of site-dependent variables permitted an increase in the across-site generalizability, thus attempting to address an important machine learning limitation.

The functioning assessment short test (FAST) applied to first-episode psychosis: Psychometric properties and severity thresholds

Functional impairment is a defining feature of psychotic disorders. The Functional Assessment Short Test (FAST) is one of the most widely used instruments to measure psychosocial functioning. However, cut-offs of impairment have been well-established for bipolar disorders, but not for other clinical populations. This study aims to analyse psychometric properties of the FAST and establish their corresponding cut-off values for the different severity gradations in a first-episode of non-affective psychosis (FEP) patients. Global Assessment Functioning (GAF) and FAST ratings from 212 non-affective FEP and 204 healthy controls were analyzed. The psychometric properties of FAST (internal consistency, concurrent validity, discriminant validity, factorial analyses and sensitivity to change) were analyzed. The severity gradations of the FAST were defined by the congruence between two grading methods: linear regression analysis (LRA) and percentiles. The FAST showed strong psychometric properties. LRA with the GAF scores yielded the following equation: GAF_score= 80.83 - 0.639*FAST_score. The FAST ranges in non-affective FEP patients derived from LRA and percentiles, were as follows: 0-9 (No impairment); 10-19 (Minimal impairment); 20-34 (Mild impairment); 35-45 (Moderate impairment); 46-72 (Severe impairment). Patients with no functional impairment had a higher socioeconomic status, fewer depressive and negative symptoms, lower severity of illness and higher cognitive reserve level than the others groups. In conclusion, the FAST shows optimal psychometric properties which corroborate its applicability in FEP populations. It is a well-demonstrated valid instrument and the present cut-off scores could be implemented in clinical and research practice to assess properly the psychosocial functional outcome of non-affective FEP populations.

Systematic comparison of duration of untreated illness versus duration of untreated psychosis in relation to psychopathology and dysfunction in the Cavan-Monaghan first episode psychosis study (CAMFEPS)

This study systematically compared duration of untreated illness (DUI) with duration of untreated psychosis (DUP) in prediction of impairment at first-episode psychosis and investigated the extent to which these relationships are influenced by premorbid features. The Cavan-Monaghan First Episode Psychosis Study ascertained cases of first-episode psychosis in rural Ireland via all routes to care with limited variations in socioeconomic milieu. Cases were evaluated for DUI and DUP and assessed clinically for psychopathology, neuropsychology, neurology, insight and quality of life, together with premorbid features. Analyses then determined prediction of clinical assessments by DUI versus DUP. The study population consisted of 163 cases of first episode psychosis, among which 74 had a schizophrenia spectrum disorder. Shorter DUI but not DUP predicted less severe positive and general symptoms, while shorter DUP and particularly DUI predicted less severe negative symptoms; neither shorter DUP nor shorter DUI predicted less severe cognitive impairment or fewer neurological soft signs; shorter DUP and DUI predicted increased quality of life; shorter DUI but not DUP predicted greater insight. Only prediction of quality of life was weakened by consideration of premorbid features. Results were generally similar across the two diagnostic groupings. The present findings systematically delineate associations with DUI versus DUP across domains of impairment in first episode psychosis. They suggest that DUI may reflect a more insidious process than DUP and that reduction in DUI may be associated with more consistent and broader diminutions in impairment than for DUP.

Mapping out the philosophical questions of AI and clinical practice in diagnosing and treating mental disorders

How to classify the human condition? This is one of the main problems psychiatry has struggled with since the first diagnostic systems. The furore over the recent editions of the diagnostic systems DSM-5 and ICD-11 has evidenced it to still pose a wicked problem. Recent advances in techniques and methods of artificial intelligence and computing power which allows for the analysis of large data sets have been proposed as a possible solution for this and other problems in classification, diagnosing, and treating mental disorders. However, mental disorders contain some specific inherent features, which require critical consideration and analysis. The promises of AI for mental disorders are threatened by the unmeasurable aspects of mental disorders, and for this reason the use of AI may lead to ethically and practically undesirable consequences in its effective processing. We consider such novel and unique questions AI presents for mental health disorders in detail and evaluate potential novel, AI-specific, ethical implications.

Exploration of symptom dimensions and duration of untreated psychosis within a staging model of schizophrenia spectrum disorders

AIM

Clinical staging of schizophrenia entails a new method that identifies clusters of symptoms and variation in level of remission, with the goal to create a framework for early intervention. Additionally, duration of untreated psychosis (DUP) may influence symptom severity in the first episode of psychosis (FEP) and could necessitate refining of the staging model. However, consistent evidence concerning variation in symptom severity and DUP between stages is missing. Therefore, we evaluated the clinical validity of the staging model by investigating differences in symptom severity across stages in schizophrenia spectrum disorders. Second, we assessed if a prolonged DUP is associated with higher symptom severity in FEP.

METHODS

We performed a cross-sectional study of 291 acutely admitted patients with a schizophrenia spectrum disorder. Patients were assigned to clinical stages following the definition of McGorry. Symptom severity was evaluated with the new DSM-5 Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS). In FEP, we determined the DUP.

RESULTS

Significantly higher severity scores of CRDPSS items hallucinations (H = 14.34, df = 4, P-value = .006), negative symptoms (H = 19.678, df = 4, P-value = .001) and impaired cognition (H = 26.294, df = 4, P-value = <.001) were found in more advanced stages of disease. Moreover, patients with FEP and a DUP longer than 1 year showed significantly more severe negative symptoms (U = 314 000, P = .015) compared to patients with a DUP shorter than 1 year.

CONCLUSIONS

The present study found supporting evidence for the clinical validity of the staging model in schizophrenia spectrum disorders. In addition, we found support for refining the stage "first episode" with information concerning the DUP.

Using Digital Tools to Engage Patients With Psychosis and Their Families in Research: Survey Recruitment and Completion in an Early Psychosis Intervention Program

BACKGROUND

Barriers to recruiting and retaining people with psychosis and their families in research are well-established, potentially biasing clinical research samples. Digital research tools, such as online platforms, mobile apps, and text messaging, have the potential to address barriers to research by facilitating remote participation. However, there has been limited research on leveraging these technologies to engage people with psychosis and their families in research.

OBJECTIVE

The objective of this study was to assess the uptake of digital tools to engage patients with provisional psychosis and their families in research and their preferences for different research administration methods.

METHODS

This study used Research Electronic Data Capture (REDCap)-a secure web-based platform with built-in tools for data collection and storage-to send web-based consent forms and surveys on service engagement via text message or email to patients and families referred to early psychosis intervention services; potential participants were also approached or reminded about the study in person. We calculated completion rates and timing using remote and in-person methods and compensation preferences.

RESULTS

A total of 447 patients with provisional psychosis and 187 of their family members agreed to receive the web-based consent form, and approximately half of the patients (216/447, 48.3%) and family members (109/187, 58.3%) consented to participate in the survey. Most patients (182/229, 79.5%) and family members (75/116, 64.7%) who completed the consent form did so remotely, with more family members (41/116, 35.3%) than patients (47/229, 20.5%) completing it in person. Of those who consented, 77.3% (167/216) of patients and 72.5% (79/109) of family members completed the survey, and most did the survey remotely. Almost all patients (418/462, 90.5%) and family members (174/190, 91.6%) requested to receive the consent form and survey by email, and only 4.1% (19/462) and 3.2% (6/190), respectively, preferred text message. Just over half of the patients (91/167, 54.5%) and family members (42/79, 53.2%) preferred to receive electronic gift cards from a coffee shop as study compensation. Most surveys were completed on weekdays between 12 PM and 6 PM.

CONCLUSIONS

When offered the choice, most participants with psychosis and their families chose remote administration methods, suggesting that digital tools may enhance research recruitment and participation in this population, particularly in the context of the COVID-19 global pandemic.

Duration of untreated illness predicts 3-year outcome in patients with obsessive-compulsive disorder: A real-world, naturalistic, follow-up study

Duration of untreated illness (DUI) is a predictor of outcome in psychotic and affective disorders. The few available data on the effect of DUI in obsessive-compulsive disorder (OCD) suggest an association between longer DUI and poorer response to treatments. This is a real-world, naturalistic, follow-up study evaluating the impact of DUI on long-term clinical outcomes. The sample consists of 83 outpatients with OCD with a mean DUI of 7.3 (5.8) years. Patients with symmetry/ordering cluster symptoms were younger at onset of the disease (20.4 ± 7.9 vs. 27.8 ± 10.6; p<.05, d = 0.79), had a longer duration of the illness (10.1 ± 4.6 vs. 6.8 ± 4.6, p<.05; d = 0.53) and a longer DUI (7.9 ± 6.5 vs. 5.4 ± 3.6, p<.05, d = 0.49) compared to patients not presenting with those symptoms. Fifty-nine patients completed the follow-up, and 33.9% (N = 20) met the criteria for partial remission, scoring <15 at the Y-BOCS for at least eight weeks. Patients in partial remission for more than 40% of the follow-up were defined as "good outcome" and they had a significantly shorter DUI compared to patients with "poor outcome". Access to adequate treatments is highly delayed in patients with OCD. DUI is strongly associated with poor treatment outcomes. Therefore, strategies to ensure an early diagnosis and treatment are needed.

[Validation of a French version of the 16-item Prodromal Questionnaire (fPQ16) in adolescents and young adults seeking help]

INTRODUCTION

The duration of untreated psychosis has been largely associated with poor outcomes in psychosis. Actual diagnostic tools may be used by very specialized teams and need sustained evaluation. We present a French version of a self-report questionnaire: the 16-item Prodromal Questionnaire (fPQ16). Our objective was to evaluate its predictive value for an ultra-high-risk state (UHR) or psychosis. The population enrolled was consulting in a young adults and adolescents center in Sainte-Anne hospital, Paris, France.

METHODS

PQ16 had first been translated into French and independently back translated and validated by the original authors. Between November 2016 and May 2018, every C'JAAD consulting patient was proposed to fill in the fPQ16. Each patient was next evaluated with the French version of the comprehensive assessment of at-risk mental state (CAARMS), which detects UHR or psychosis. Statistical analysis of fPQ16 concurrent validity was performed using ROC curves. fPQ16 acceptability was studied by four additional questions especially designed for that purpose.

RESULTS

One hundred participants were included. Mean age was 19.85years (SD 3.3 y). Fifty-eight percent of patients included were diagnosed with UHR (40%) or psychotic (18%) state after CAARMS evaluation. Mean score at fPQ16 was 5.7 (SD 3.8). Best cut-off score was 4 positive items, with excellent sensibility (91%) and correct specificity (60%). Positive predictive value of fPQ16 was 76%. Area under the curve was 0.85 (P<0.0001). fPQ16 showed good acceptability.

DISCUSSION

fPQ16 had good screening performances in our population. Cut-off score was lower than in previous studies, but performances were equal or better. As a well-accepted and short questionnaire, the fPQ16 could be a great screening tool in primary care. A version with 18-items, including two items focused on thought content and disorganization that are missing in PQ16, is under evaluation.

The influence of romantic relationships on mental wellbeing for people who experience psychosis: A systematic review

PURPOSE

Whilst it is generally accepted that supportive relationships facilitate recovery from psychosis, much less is known about the role of romantic relationships in people with psychosis. This review aimed to synthesise quantitative literature regarding the impact of romantic relationships on the mental health and general wellbeing of people who experience psychosis.

METHOD

A systematic review of electronic databases (PsychINFO, PubMed, Web of Science) was carried out using search terms relating to psychosis and romantic relationships. Papers were selected for inclusion by independent reviewers. Quality assessment was completed and a narrative synthesis produced.

RESULTS

Fifty-eight studies reporting the association between romantic relationships and psychotic symptoms, depression, posttraumatic stress disorder, suicidality, quality of life, satisfaction with life and self-esteem were included. Results were mixed but indicated having a romantic partner may be associated with reduced positive and negative symptoms of psychosis, but increased depressive symptoms. Tentative explanations for these findings, such as functioning prior to onset of psychosis, social support and relationship quality are explored.

CONCLUSION

Findings highlight the importance of this often-overlooked area in clinical practice. Studies with robust design, which specifically aim to understand the relationship between romantic relationships and wellbeing for people who experience psychosis are needed.

Experiences of pathways to mental health services for young people and their carers: a qualitative meta-synthesis review

Worldwide, growing concern with young people's mental health is spurring service reform efforts. Such reform requires a full understanding of the experiences of young people and their carers when seeking mental health help. To generate such an understanding, we conducted a meta-synthesis of qualitative literature on the perspectives of youths and their carers on navigating mental health systems. Five electronic databases were searched (Medline, PsycINFO, EMBASE, CINAHL, HealthSTAR). Studies were included if they explored the experiences of pathways to mental health services of persons aged 11-30 years and/or their carers; were published in English or French; and used qualitative methodology. Quality appraisal was conducted using the CASP tool. The synthesis of 31 included studies yielded three themes-initiating contact with mental health services; characteristics of services' response; and youths' and carers' appraisal of services. Themes about initiating contact included mental health literacy, structural barriers, and social support. Service response-related themes included complex pathways, waitlists, eligibility, and fragmented care. In terms of service appraisal, positive encounters featured providers who were accessible and perceived as caring. Negative appraisals resulted from feeling misunderstood and excluded and being ill-informed about treatment. Across diagnoses and settings, youths and carers had difficult experiences accessing mental healthcare. While individual, social, and healthcare factors shaping pathways to care varied, systemic complexities were a common inhibitor. This synthesis informs recommendations for improving mental health services and youths' pathways to them. It underlines the need for grounding reform in youths' and carers' perspectives and needs.
