ItemStaged Treatment in Early Psychosis: A sequential multiple assignment randomised trial of interventions for ultra high risk of psychosis patients(WILEY, 2018-06)AIM: Previous research indicates that preventive intervention is likely to benefit patients "at risk" of psychosis, in terms of functional improvement, symptom reduction and delay or prevention of onset of threshold psychotic disorder. The primary aim of the current study is to test outcomes of ultra high risk (UHR) patients, primarily functional outcome, in response to a sequential intervention strategy consisting of support and problem solving (SPS), cognitive-behavioural case management and antidepressant medication. A secondary aim is to test biological and psychological variables that moderate and mediate response to this sequential treatment strategy. METHODS: This is a sequential multiple assignment randomised trial (SMART) consisting of three steps: Step 1: SPS (1.5 months); Step 2: SPS vs Cognitive Behavioural Case Management (4.5 months); Step 3: Cognitive Behavioural Case Management + Antidepressant Medication vs Cognitive Behavioural Case Management + Placebo (6 months). The intervention is of 12 months duration in total and participants will be followed up at 18 months and 24 months post baseline. CONCLUSION: This paper reports on the rationale and protocol of the Staged Treatment in Early Psychosis (STEP) study. With a large sample of 500 UHR participants this study will investigate the most effective type and sequence of treatments for improving functioning and reducing the risk of developing psychotic disorder in this clinical population.

ItemDevelopment of an implementation guide to facilitate the roll-out of early intervention services for psychosis(WILEY, 2018-12)AIM: Our aim was to develop an implementation guide that was informed by an analysis of context-specific barriers and enablers, behaviour change theory, as well as evidence about the effects of implementation interventions, for the establishment and scaling up of an early intervention model for psychosis (called Early Psychosis Prevention and Intervention Centre (EPPIC)). METHODS: We used a systematic approach involving four steps. First, the target behaviours of the EPPIC model for implementation were specified. Second, a consultation was undertaken to explore the barriers and enablers to undertaking these priority minimum standard clinical behaviours. Third, an implementation strategy that included a range of behaviour change techniques tailored to address the identified barriers was developed. Finally, a tool to assess whether those implementing the EPPIC model maintained fidelity to the implementation strategy was designed. RESULTS: We identified a range of barriers that could act to dilute the core components of the EPPIC model and compromise its implementation. An implementation strategy using theory and evidence-based strategies for behaviour change was designed to address these barriers. CONCLUSIONS: The process we used in the development of the implementation strategy provided a unique opportunity to consider the essential areas to cover, how to make information easily understandable and accessible while noting the complexity of issues involved in not only implementation, but also the scaling up of the EPPIC model for services.

ItemModerated online social therapy for depression relapse prevention in young people: pilot study of a "next generation' online intervention(WILEY, 2018-08)AIM: Implementation of targeted e-mental health interventions offers a promising solution to reducing the burden of disease associated with youth depression. A single-group pilot study was conducted to evaluate the acceptability, feasibility, usability and safety of a novel, moderated online social therapy intervention (entitled Rebound) for depression relapse prevention in young people. METHODS: Participants were 42 young people (15-25 years) (50% men; mean age = 18.5 years) in partial or full remission. Participants had access to the Rebound platform for at least 12 weeks, including the social networking, peer and clinical moderator and therapy components. RESULTS: Follow-up data were available for 39 (92.9%) participants. There was high system usage, with 3034 user logins (mean = 72.2 per user) and 2146 posts (mean = 51.1). Almost 70% of users had ≥10 logins over the 12 weeks, with 78.5% logging in over at least 2 months of the pilot. A total of 32 (84%) participants rated the intervention as helpful. There was significant improvement between the number of participants in full remission at baseline (n = 5; none of whom relapsed) relative to n = 19 at 12-week follow-up (P < 0.001). Six (14.3%) participants relapsed to full threshold symptoms at 12 weeks. There was a significant improvement to interviewer-rated depression scores (Montgomery-Asberg Depression Rating Scale (MADRS); P = 0.014, d = 0.45) and a trend for improved strength use (P = 0.088, d = 0.29). The single-group design and 12-week treatment phase preclude a full understanding of the clinical benefits of the Rebound intervention. CONCLUSIONS: The Rebound intervention was shown to be acceptable, feasible, highly usable and safe in young people with major depression.

ItemYouth mental health services in Italy: An achievable dream?(WILEY, 2018-06)AIM: "Liberiamo il futuro" (LIF) project was designed to assess psychological problems of adolescents and young adults and to identify individuals at high-risk for developing a psychosis through a collaboration between a University team, Child and Adolescent Mental Health Services and Adult Mental Health Services. This paper presents the baseline demographic and clinical characteristics of the cohort, particularly the nature and severity of psychopathology. METHOD: All help-seeking young people aged 12-35 years residing in the health district involved in LIF were invited to participate in the study and completed a battery of self- report and interviewer-administered measures of psychopathology and functioning at baseline. RESULTS: A total of 338 adolescents and young people (mean age 17.42) participated in the study. The majority of the sample (n = 107, 35%) had an anxiety disorder, followed by mood disorders (n = 62, 21%). Only 35 (12%) participants had no psychiatric diagnosis. After a screening phase, 166 (52%) individuals were assessed to detect the presence of an Ultra High Risk (UHR) state. Of these, 38.60% (n = 64) met UHR criteria. Overall, the majority of the sample resulted moderately functionally impaired at baseline. CONCLUSIONS: LIF project showed that psychological problems, associated with impaired psychosocial functioning, are very common among help-seeking young people. The help-seeking behaviour of young people is in contrast with the barriers presented by the Italian community mental health system that is modelled around adults' requirements. A need of a strong, stigma-free, young oriented system of care for young people up to the mid-20s emerged.

ItemDifferential effect of quetiapine and lithium on functional connectivity of the striatum in first episode mania(NATURE PUBLISHING GROUP, 2018-03-06)Mood disturbances seen in first-episode mania (FEM) are linked to disturbed functional connectivity of the striatum. Lithium and quetiapine are effective treatments for mania but their neurobiological effects remain largely unknown. We conducted a single-blinded randomized controlled maintenance trial in 61 FEM patients and 30 healthy controls. Patients were stabilized for a minimum of 2 weeks on lithium plus quetiapine then randomly assigned to either lithium (serum level 0.6 mmol/L) or quetiapine (dosed up to 800 mg/day) treatment for 12 months. Resting-state fMRI was acquired at baseline, 3 months (patient only) and 12 months. The effects of treatment group, time and their interaction, on striatal functional connectivity were assessed using voxel-wise general linear modelling. At baseline, FEM patients showed reduced connectivity in the dorsal (p = 0.05) and caudal (p = 0.008) cortico-striatal systems when compared to healthy controls at baseline. FEM patients also showed increased connectivity in a circuit linking the ventral striatum with the medial orbitofrontal cortex, cerebellum and thalamus (p = 0.02). Longitudinally, we found a significant interaction between time and treatment group, such that lithium was more rapid, compared to quetiapine, in normalizing abnormally increased functional connectivity, as assessed at 3-month and 12-month follow-ups. The results suggest that FEM is associated with reduced connectivity in dorsal and caudal corticostriatal systems, as well as increased functional connectivity of ventral striatal systems. Lithium appears to act more rapidly than quetiapine in normalizing hyperconnectivity of the ventral striatum with the cerebellum. The study was registered on the Australian and New Zealand Clinical Trials Registry (ACTRN12607000639426). http://www.anzctr.org.au.

ItemManaging the link and strengthening transition from child to adult mental health Care in Europe (MILESTONE): background, rationale and methodology(BMC, 2018-06-04)BACKGROUND: Transition from distinct Child and Adolescent Mental Health (CAMHS) to Adult Mental Health Services (AMHS) is beset with multitude of problems affecting continuity of care for young people with mental health needs. Transition-related discontinuity of care is a major health, socioeconomic and societal challenge globally. The overall aim of the Managing the Link and Strengthening Transition from Child to Adult Mental Health Care in Europe (MILESTONE) project (2014-19) is to improve transition from CAMHS to AMHS in diverse healthcare settings across Europe. MILESTONE focuses on current service provision in Europe, new transition-related measures, long term outcomes of young people leaving CAMHS, improving transitional care through 'managed transition', ethics of transitioning and the training of health care professionals. METHODS: Data will be collected via systematic literature reviews, pan-European surveys, and focus groups with service providers, users and carers, and members of youth advocacy and mental health advocacy groups. A prospective cohort study will be conducted with a nested cluster randomised controlled trial in eight European Union (EU) countries (Belgium, Croatia, France, Germany, Ireland, Italy, Netherlands, UK) involving over 1000 CAMHS users, their carers, and clinicians. DISCUSSION: Improving transitional care can facilitate not only recovery but also mental health promotion and mental illness prevention for young people. MILESTONE will provide evidence of the organisational structures and processes influencing transition at the service interface across differing healthcare models in Europe and longitudinal outcomes for young people leaving CAMHS, solutions for improving transitional care in a cost-effective manner, training modules for clinicians, and commissioning and policy guidelines for service providers and policy makers. TRIAL REGISTRATION: "MILESTONE study" registration: ISRCTN ISRCTN83240263 Registered 23 July 2015; ClinicalTrials.gov NCT03013595 Registered 6 January 2017.

ItemNEURAPRO: a multi-centre RCT of omega-3 polyunsaturated fatty acids versus placebo in young people at ultra-high risk of psychotic disorders-medium-term follow-up and clinical course.(Springer Science and Business Media LLC, 2018-06-25)This study reports a medium-term follow-up of a randomised, double-blind, placebo-controlled trial of omega-3 polyunsaturated fatty acids (PUFA) in ultra-high risk for psychosis (UHR) patients. Primary outcomes of interest were transition to psychosis and symptomatic and functional outcome. A secondary aim was to investigate clinical predictors of medium-term outcome. Three hundred four UHR participants were recruited across 10 specialised early psychosis services in Australia, Asia, and Europe. The intervention consisted of 1.4 g/daily of omega-3 PUFA or placebo, plus up to 20 sessions of cognitive-behavioural case management (CBCM), over the 6-month study period, with participants receiving further CBCM sessions on basis of need between months 6-12. Mean time to follow-up was 3.4 (median = 3.3; SD = 0.9) years. There was a modest increase in transitions between 12-month and medium-term follow-up (11-13%) and substantial improvement in symptoms and functioning between baseline and follow-up, with no differences between the treatment groups. Most improvement had been achieved by end of the intervention. 55% of the sample received mental health treatment between end of intervention and follow-up. Omega-3 PUFA did not provide additional benefits to good quality psychosocial intervention over the medium term. Although most improvement had been achieved by end of intervention the substantial rates of post-intervention mental health service use indicate longer-term clinical need in UHR patients. The post-intervention phase treatment or the longer-term effect of CBCM, or a combination of the two, may have contributed to maintaining the gains achieved during the intervention phase and prevented significant deterioration after this time.
