Integrative Neuro-social cognitive Strategy Programme for Instilling REcovery (INSPIRE): a community-based cognitive remediation trial-study procotol.

BACKGROUND: Adults with schizophrenia experience a range of neurocognitive problems that affect their daily functioning. Evidence for the efficacy of cognitive remediation in schizophrenia has been established, but its implementation in under-resourced community-based settings is less well-studied. In recent years, interventions have also focused on the strategy-learning approach in favor of drill-and-practice. Moreover, there is an increasing recognition to address social cognition and negative symptoms alongside neurocognition. This study attempts to carry out cognitive remediation in a community mental health setting. The Neuropsychological and Educational Approach to Remediation (NEAR) is used as the cognitive remediation intervention. Neurocognitive and social cognitive games will be introduced during the computer-assisted cognitive exercises sessions. In addition, the instructional technique will foster the use of metacognition and cognitive strategies. Moreover, metamotivation training will be the focus of some bridging sessions to enhance motivation to engage in goal-directed learning behaviors. The aims of the study are to 1) investigate the effects of cognitive remediation on neurocognition, social cognition and functional outcomes of participants with schizophrenia/schizoaffective disorders in community mental health settings; and 2) explore the mediators for change (eg: metamotivation, metacognition and negative symptoms) in cognitive performance and functional outcomes. METHODS: This randomized controlled trial will be conducted in three Singapore Anglican Community Services (SACS) centers, where standard psychiatric rehabilitation is delivered. Participants who are randomized to the experimental arm will receive cognitive remediation and psychiatric rehabilitation, while those randomized to the control arm will receive standard psychiatric rehabilitation only. Cognitive remediation is carried out three times a week for 12 weeks. It consists of computer-assisted cognitive exercises, as well as bridging groups to aid transfer of learning to daily living. Baseline, post-intervention and eight-week follow-up measurements will be collected. Group by time differences in cognitive performance, negative symptoms, metamotivation, metacognition, functioning and recovery will be analyzed across the three time points. Mediators for improvement in cognitive performance and functioning will also be explored. DISCUSSION: Findings of this research will add to the body of knowledge about the key therapeutic ingredients within a strategy-based cognitive remediation program and improve its implementation within under-resourced community settings. TRIAL REGISTRATION: This study has been registered with ClinicalTrials.gov (ID: NCT06286202). Date of registration: 29 February 2024. Date of last update: 21 May 2024.

Accepting and committing to caregiving for schizophrenia-a mixed method pilot study.

BACKGROUND: End of traditional institutionalized psychiatric care, diagnostic complexities, and associated stigma often negatively impact the social networks of caregivers, making them experience social isolation. Not the "identified patients", caregiver perspectives are typically overlooked further adding to anticipatory stigma resulting in social death among them. Caregiving experience results in developing coping skills, preventing carers from responding to the nuances of the context, and identifying the useful rules- "Experiential Avoidance". Psycho-education is typically combined with other formal treatment programs for case conceptualization, and to provide a clear rationale for the treatment approach but less as a distinct psychotherapy. Borrowing the philosophy of Functional Contextualism, the present study developed a "Present-Moment Awareness" guided psychoeducational intervention. The aim was to reduce schizophrenia caregiver burden and anticipatory stigma and promote the value of caregiver participation as 'experts by experience'. METHOD: Five family caregivers of remitted schizophrenia patients were recruited using purposive sampling. Pre-post measure was taken on caregiver burden, caregiving experience, sense of personal mastery, and caregiving competence. Results were analysed quantitatively and qualitatively. RESULTS: A significant decrease in caregiver burden, stigma, and negative effects on the family in post-intervention was observed. Self-compassion led to a rise in a sense of empowerment. CONCLUSION: A caregiver-centred "Present-Moment Awareness" guided psycho-education for schizophrenia caregivers can be considered a possible means to address perceived stigma in caregivers and to reduce associated distress of carers.

Psychological interventions for early-phase schizophrenia: protocol for a systematic review and network meta-analysis.

Introduction: Treating the early phase of schizophrenia is crucial for preventing further episodes and improving quality of life, functioning, and social inclusion. Pharmacotherapies are first-line treatments, but have limitations. There is consensus on the need for non-pharmacological interventions for individuals in the early phase of schizophrenia. Several psychological interventions have shown promising effects; however, their comparative effectiveness remains largely unknown. To address this issue, a network meta-analysis will be performed. We aim to develop a hierarchy of existing psychological treatments concerning their efficacy and tolerability, which will inform treatment guidelines. Protocol: Randomized controlled trials (RCTs) investigating psychological interventions for first-episode psychosis, first-episode schizophrenia, or early phase schizophrenia will be included. The primary outcome will be overall schizophrenia symptoms (measured up to 6 and 12 months, and at the longest follow-up) and relapse as a co-primary outcome. Secondary outcomes are premature discontinuation; change in positive, negative, and depressive symptoms of schizophrenia; response; quality of life; overall functioning; satisfaction with care; adherence; adverse events; and mortality. The study selection and data extraction are performed by two independent reviewers. We will assess the risk of bias of each study using the Cochrane Risk of Bias tool 2 and evaluate the confidence in the results using Confidence in Network Meta-Analysis (CINeMA). Subgroup and sensitivity analyses will be conducted to explore heterogeneity and assess the robustness of our findings. Discussion: This systematic review and network meta-analysis aims to compare multiple existing psychological interventions, establishing which are best for symptom reduction, relapse prevention, and other important outcomes in early phase schizophrenia. Our results may provide practical guidance concerning the most effective psychological intervention to reduce symptom severity and the societal burden associated with the disorder.

A study investigating the implementation of NICE recommended psychological interventions for people with psychosis following a psychiatric inpatient admission.

The period of time following discharge from an inpatient setting presents a unique window of opportunity for people with psychosis to engage in psychological treatment. In England, The National Institute for Health and Care Excellence (NICE) guidelines outline that every person with a schizophrenia diagnosis should be offered individual Cognitive Behavioural Therapy for psychosis (CBTp) and Family Intervention (FI). This study aimed to explore rates of offer and receipt of NICE recommended therapies for adults with a schizophrenia spectrum disorder diagnosis in the year following discharge from an inpatient unit. We then investigated possible predictors of therapy offer and receipt. We used a large electronic healthcare records database to perform a secondary data analysis. A generalised linear regression model was used to explore possible predictors. Overall, our results showed low rates of offer and receipt of recommended therapies (Any recommended therapy (CBT only, FI only or CBT + FI) received = 39(8%), offered = 70(15%)). Predictor variable results were identified and discussed. The low level of offer and receipt of recommended therapies is concerning given the recommendations in the NICE guidelines for people with psychosis. Our study highlighted the need for more consistent and reliable procedures for recording this information. Further investigation into the reasons for low levels of implementation overall is important to aid the development of recommendations for how this can be improved.

Functioning Management and Recovery, a psychoeducational intervention for psychiatric residential facilities: a multicenter follow-up study.

AIM: Functional Management and Recovery is a standardized Psychoeducational Intervention, derived from "Integro", an effective salutogenic-psychoeducational intervention for people in recovery journey, designed to improve recovery and functioning of individuals with psychotic disorders in Psychiatric Residential Facilities (PRFs). The aim of this study is to evaluate the primary and secondary outcomes of this intervention elaborated specifically for PRFs where evidence based structured interventions seem rare and desirable. METHODS: 66 individuals with psychotic disorders were recruited in 9 PRFs dislocated in the North, Center and South Italy and 63 underwent a multicenter follow-up study with a two time-point evaluation (t0, pre-treatment and t1, 6 months; ). At each time point, social functioning was assessed as primary outcome by the Personal and Social Performance scale (PSP); furthermore, psychopathological status was assessed by Brief Psychiatric Rating Scale (BPRS), Recovery by Recovery Assessment Scale (RAS), Cognitive Functioning by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Stress management by Stress-Scale, Cognitive Flexibility by Modified Five-Point Test (M-FPT), Emotional Intelligence by Emotional Intelligence Index (EI-I), the PRF Atmosphere and the Opinion of users about the PFR by an ad hoc questionnaire. The Abilities Knowledge, the Utility and Pleasantness of sessions were measured by an ad hoc list of items. RESULTS: 63 individuals out of 66, 52 (82,5%) affected by schizophrenia and 11 (17,5%) by bipolar I disorder with psychotic symptoms according to DSM-5-TR completed the study. At the end of the study, 43 (68,3%) were male, 57 (90.5%) were single, 5 (7.9%) engaged, 1 (1.6%) married; 45 (71.4%) unemployed. The total scores of PSP, RAS, BPRS, BANS, Stress management, Abilities Knowledge, Utility and Pleasantness of sessions showed a statistically significant improvement at t1 vs. t0. Two sub-scales out of 5 of M-FPT showed a statistically significant improvement. The Emotional Intelligence, the Unit Atmosphere and the Opinion of Users about PFR improved without statistical significance. Six months after the end of the follow-up study 22 individuals of the sample were dismissed with a very high turnover. CONCLUSIONS: After a six-month follow-up (a short period of time), these results showed improvement in functioning, the primary outcome, as well as in the following secondary outcome variables: RAS, BPRS, BANS, Stress management, Abilities Knowledge, two sub-scales out of 5 of M-FPT, Utility and Pleasantness of sessions. Overall, a remarkable impact of psychoeducational structured intervention on the key Recovery variables is observed. Further studies are needed to address extent and duration of these improvements.

Biomarkers of Electroconvulsive Therapy (ECT) Response in Treatment-resistant Schizophrenia (TRS).

Electroconvulsive therapy (ECT) is a well-established treatment option for individuals with treatment-resistant schizophrenia (TRS). However, predicting treatment response and identifying potential biomarkers to guide electroconvulsive therapy interventions in treatment-resistant schizophrenia remains a challenge. This review paper aims to explore the current literature on clinical biomarkers associated with electroconvulsive therapy in treatment-resistant schizophrenia. We discuss various potential biomarkers, including clinical, neuroimaging findings, EEG markers, and genetic markers, that have shown promise in predicting electroconvulsive therapy response and understanding the underlying mechanism of action. Additionally, we highlight the limitations and future directions for research in this field.

Early Intervention in the Treatment of Psychosis.

This article aims to: (1) describe the evolution of first episode of psychosis (FEP) approaches; (2) define a model of multidisciplinary care; (3) identify challenges and limitations; (4) discuss the unique challenges for those first experiencing psychosis; (5) identify strategies to expand early psychosis interventions. The authors take the medical standpoint and use the differential diagnosis and initial medical work-up as a context for assessment. The remainder of the article will be focused on treatment of FEP in those with schizophrenia-spectrum disorders.

Cognitive-behavioral therapy for negative symptoms of schizophrenia: A systematic review and meta-analysis.

BACKGROUND: Cognitive-behavioral intervention techniques are increasingly demonstrating their efficacy in preventing relapses and managing problems in patients with schizophrenia. There is still variation in its effectiveness for negative symptoms, such as mood-related symptoms and motivation to engage socially. METHODS: A systematic search was conducted in PubMed, Web of Science for English literature on cognitive-behavioral therapy (CBT) interventions in patients with schizophrenia. The search included randomized controlled trials and nonrandomized controlled trials. The search period extended from the inception of the databases to September 30, 2022. Two researchers independently performed quality assessment and data extraction based on predefined inclusion and exclusion criteria. RESULTS: Discrepancies were resolved through discussion or consultation with a third researcher. Initially, 169 articles were retrieved through database searches and other means. After applying the inclusion and exclusion criteria, 10 randomized controlled studies were included in the final analysis. The intervention group comprised a total of 680 patients with schizophrenia, while the control group included 686 patients with schizophrenia. Meta-analysis results demonstrated a statistically significant difference in negative symptom reduction between the CBT intervention group (WMD = -1.19, 95% CI [-1.73, -0.66], P < .0001) and the control group. CONCLUSION: We have analyzed the effectiveness of CBT based on our previous research, CBT was found to effectively improve negative symptoms in individuals diagnosed with schizophrenia.

The role of motivation in clinical presentation, treatment engagement and response in schizophrenia-spectrum disorders: A systematic review.

Schizophrenia, a debilitating psychiatric disorder, has a long-term impact on social and occupational functioning. While negative symptoms, notably amotivation, are recognized as poor prognostic factors, the positive force of patient motivation (autonomous motivation) remains underexplored. This systematic review, guided by Self-Determination Theory (SDT), investigated the impact of motivation on clinical presentation, and treatment engagement and response in schizophrenia-spectrum disorders. Fifty-five independent studies (N = 6897), using 23 different motivation scales, met inclusion criteria. Results were categorized into cross-sectional and longitudinal correlates of autonomous motivation, and the effects of motivational interventions. Cross-sectionally, autonomous motivation was positively associated with social/occupational functioning, and negatively associated with negative and positive symptom severity. In longitudinal studies, baseline autonomous motivation predicted engagement in and response to social/occupational treatments, with mixed results in cognitive interventions. In the 16 randomized controlled trials (RCTs), the most common motivational interventions were individualized goal setting and goal attainment support, followed by increasing sense of competence by challenging defeatist beliefs, and enhancing relatedness by increasing contact time. Motivational interventions consistently increased autonomous motivation, treatment engagement and response. More studies are needed, particularly studies that monitor motivation during treatment: proximal assessments could facilitate the identification of treatment elements that impact motivation and engagement and inform treatment modifications to enhance the patient experience and improve treatment efficacy.

Cognitive training for schizophrenia: Do race and ethnicity matter?

Racial disparities in diagnosis, treatment, and outcome have been well-established for people with schizophrenia. While cognitive remediation treatments have been shown to produce mild to moderate improvements in cognition for people with schizophrenia, few studies have examined racial/ethnic differences in treatment response. This study employed a secondary analysis of data from two randomized, single-blind controlled trials (N = 119) investigating the efficacy of two forms of cognitive training, to explore potential racial/ethnic differences in targeted outcomes. Given the extant literature, we predicted that racial/ethnic minorities would (1) drop out of the study at higher rates, (2) display greater levels of functional and cognitive impairment prior to treatment, and (3) display lower levels of improvement in cognitive and functioning outcomes following treatment. Our study revealed largely negative findings: white vs. non-white groups showed similar treatment drop-out rates, similar levels of cognitive impairment and symptom severity at study baseline and showed similar responses to cognitive training, with the exception of working memory in which participants' racial/ethnic minority status predicted significantly greater improvement in response to cognitive training. These findings suggest that cognitive remediation treatments are effective at addressing cognitive deficits in racial/ethnic minorities and supports cognitive remediation as a treatment which may help address racial/ethnic disparities in cognition. Given the scant research literature, future analyses should look at race as a potential mediator of treatment in a variety of evidence-based psychosocial treatments.

Circadian lighting effect for inpatients with schizophrenia: A prospective cohort study.

OBJECTIVES: In schizophrenia, nonspecific lighting likely causes sleep timing disturbances, leading to distress and poorer clinical status. However, the effect of exposure to circadian lighting on psychopathology outcome in schizophrenia remains unknown. Hence, this study aimed to develop such an intervention and investigate its impact on schizophrenia. METHODS: Twenty schizophrenia patients at a psychiatric nursing institute were monitored over 10 weeks, with assessments using the Brief Psychiatric Rating Scale (BPRS) and Mini-Mental State Examination (MMSE) conducted at baseline, weeks 3 (T1), 7 (T2), and 10 (T3). RESULTS: Circadian lighting significantly improved BPRS scores between T1-T2 (p < .05) and T1-T3 (p < .001), with affectivity scores also showing significant enhancements postintervention. Notably, female participants exhibited substantial improvements in BPRS scores from T1 to T3 (p < .01), while male participants demonstrated significant gains in MMSE scores from T1 to T2 (p < .01). CONCLUSIONS: Circadian lighting presents a promising intervention for improving psychiatric outcomes in schizophrenia, with distinct benefits observed across different psychopathological aspects and genders. These findings underscore the potential of lighting chronotherapy in psychiatric clinical practice and warrant further exploration in related research.

Factors Associated with Readmission within 30 Days of Hospital Discharge of Psychiatric Patients: Case-Control Study.

BACKGROUND: Readmission, defined as any admission after discharge from the same hospital, has negative implications for health outcomes. This study aims to identify the sociodemographic and clinical factors associated with hospital readmission among psychiatric patients. METHODOLOGY: This case-control study analyzed 202 clinical records of patients admitted to a psychiatric hospital between 2019-2021. The sample was selected using simple random sampling. Qualitative variables were presented using frequencies, percentages, and chi-square tests for association. Quantitative variables were described using central tendency measures and dispersion of data, investigated with the Kolmogorov-Smirnov test, Student's t-test or Wilcoxon test as appropriate. Regression analysis was conducted to determine factors linked to readmission. p < 0.05 was considered. RESULTS: Women accounted for a higher readmission rate (59%). Patients diagnosed with schizophrenia had a higher readmission rate (63%), experienced longer transfer times to the hospital during readmissions, and had shorter hospital stays. Polypharmacy and pharmacological interactions were associated with readmission. Olanzapine treatment was identified as a risk factor for readmission (ExpB = 3.203, 95% CI 1.405-7.306, p = 0.006). CONCLUSIONS: The findings suggest avoiding polypharmacy and medications with high side effect profiles to reduce readmissions. This study offers valuable insights for clinical decision-making from admission to discharge planning, aiming to enhance the quality of care.

Self-Harm and Suicide Rates Before and After an Early Intervention Program for Patients With First-Episode Schizophrenia.

Importance: Evidence on the association of early intervention services (EISs) with self-harm and suicide among patients with first-episode schizophrenia (FES) at older than 25 years is lacking. Objective: To examine changes in self-harm and suicide rates among patients with FES before and after the implementation of an EIS program. Design, Setting, and Participants: This population-based cohort study conducted among 37 040 patients aged 15 to 64 years with FES between January 1, 2001, and March 31, 2020, used electronic medical records from the Hong Kong Clinical Data Analysis and Reporting System. All patients were followed up from the first diagnosis of schizophrenia (the index date) until the date of their death or the end of the study period (March 31, 2021), whichever came first. Statistical analysis was performed from July to November 2023. Exposure: The EIS extended the Early Assessment Service for Young People With Early Psychosis (EASY) program from patients aged 15 to 25 years to those aged 15 to 64 years (EASY Plus). The exposure was the implementation of the EASY Plus program in April 2011. The exposure period was defined as between April 2012 and March 2021 for the 1-year-time-lag analysis. Main Outcomes and Measures: The outcomes were monthly rates of self-harm and suicide among patients with FES before and after the implementation of the EASY Plus program. Interrupted time series analysis was used for the main analysis. Results: This study included 37 040 patients with FES (mean [SD] age at onset, 39 [12] years; 82.6% older than 25 years; 53.0% female patients). The 1-year-time-lag analysis found an immediate decrease in self-harm rates among patients aged 26 to 44 years (rate ratio [RR], 0.77 [95% CI, 0.59-1.00]) and 45 to 64 years (RR, 0.70 [95% CI, 0.49-1.00]) and among male patients (RR, 0.71 [95% CI, 0.56-0.91]). A significant long-term decrease in self-harm rates was found for all patients with FES (patients aged 15-25 years: RR, 0.98 [95% CI, 0.97-1.00]; patients aged 26-44 years: RR, 0.98 [95% CI, 0.97-0.99]; patients aged 45-64 years: RR, 0.97 [95% CI, 0.96-0.98]). Suicide rates decreased immediately after the implementation of the EASY Plus program among patients aged 15 to 25 years (RR, 0.33 [95% CI, 0.14-0.77]) and 26 to 44 years (RR, 0.38 [95% CI, 0.20-0.73]). Compared with the counterfactual scenario, the EASY Plus program might have led to 6302 fewer self-harm episodes among patients aged 26 to 44 years. Conclusions and Relevance: This cohort study of the EASY Plus program suggests that the extended EIS was associated with reduced self-harm and suicide rates among all patients with FES, including those older than 25 years. These findings emphasize the importance of developing tailored interventions for patients across all age ranges to maximize the benefits of EISs.

The Economic Impact of Cognitive Impairment and Negative Symptoms in Schizophrenia: A Targeted Literature Review With a Focus on Outcomes Relevant to Health Care Decision-Makers in the United States.

Abstract.Objective: To conduct a targeted literature review to examine the impact of cognitive impairment and negative symptoms among patients with schizophrenia treated in the United States across a range of outcomes pertinent to the US health care system decision-makers, such as payers and policy-makers.Data Sources: The authors searched EMBASE and PubMed from January 2012 to January 2024. Search terms included schizophrenia, cognitive impairment and negative symptoms, and direct medical and nonmedical, indirect, and societal outcomes.Study Selection: Considered for inclusion were US-based studies reporting on the relationship between cognitive impairment or negative symptoms and direct medical and nonmedical, indirect, and societal outcomes in patients with schizophrenia. A total of 4,212 articles were initially identified for screening.Data Extraction: One reviewer extracted data and another reviewer ensured studies met Population, Intervention, Comparison, Outcomes, Study Design-Time Period (PICOS-T) criteria for inclusion and exclusion.Results: Eight studies (n = 262,683) were included that reported specifically on associations between cognitive impairment or negative symptoms and targeted outcomes. Patients with schizophrenia and moderate/severe cognitive impairment had a 100% increase in relapse-related hospitalizations (0.6 vs 0.3, adjusted incidence rate ratio = 1.85, P < .05) and ER visits (0.4 vs 0.2, adjusted odds ratio = 1.77, P < .05) vs patients with no/mild cognitive impairment. Additionally, there was an almost 50% increase in outpatient visits (8.4 vs 5.5, P < .001) and inpatient admissions (6.8 vs 4.5, P < .001) over the study period (2014 Q1-2017 Q4) for patients with negative symptoms vs without negative symptoms. Direct nonmedical, indirect, and societal outcomes are described.Conclusions: This review highlights the economic burden of cognitive impairment and negative symptoms by focusing on outcomes relevant to health care decision-makers in the United States.

Changes in brain-derived neurotrophic factors in schizophrenic patients with spiritual psychoreligious therapy.

Objectives: To examine the effect of Spiritual Quranic Emotional Freedom Technique therapy on the level of brain-derived neurotrophic factor in schizophrenic patients. METHODS: The quasi-experimental study was conducted from August to December 2021 at the Polytechnic of Health, Kendari, Indonesia, and comprised patients of either gender aged >20 years who had been diagnosed with schizophrenia by psychiatrists using the text-revised version of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, had Brief Psychiatric Rating Scale score 50-60, and were part of the treatment programme at the polyclinic. They were divided into experimental group A and control group B. Patients in group A were given 30 days of Spiritual Quranic Emotional Freedom Technique therapy, while those in group B received only education about the spiritual therapy with the recommendation to listen to the Quran verses. A set of healthy controls memorizing the Quran was enrolled from the Islamic Boarding School, Kendari, and placed in group C. They were given education about the need to keep reading and learning the Quran. The intervention was done 2 times per week for 4 weeks. Serum brain-derived neurotrophic factor level for all groups and the Brief Psychiatric Rating Scale score for groups A and B were assessed at baseline and post-intervention. Data was analysed using SPSS 22. RESULTS: Of the 30 subjects, 16(53.3%) were females and 14(46.7%) were males. There were 11(36.7%) subjects aged 31-40 years. Each of the 3 groups had 10(33.3%) subjects. There was a significant decrease in Brief Psychiatric Rating Scale scores in groups A and B post-intervention (p<0.000). There was a significant increase in serum brain-derived neurotrophic factor levels post-therapy in groups A and C (p<0.001), while in group B it was not significant (p=0.500). CONCLUSIONS: Spiritual Quranic Emotional Freedom Technique therapy could enhance clinical improvement and brain function in schizophrenic patients.

Neurocognitive effects of 3 mA prefrontal electrical stimulation in schizophrenia: A randomized sham-controlled tDCS-fMRI study protocol.

BACKGROUND: Schizophrenia (SCZ) is characterized by cognitive deficits that are linked to prefrontal cortex dysfunction. While transcranial direct current stimulation (tDCS) shows promise for improving cognition, the effects of intensified 3mA tDCS protocols on brain physiology are unknown. This project aims to elucidate the neurophysiological and cognitive effects of an intensified prefrontal tDCS protocol in SCZ. METHODS: The study is designed as a randomized, double-blind, 2-arm parallel-group, sham-controlled, trial. Forty-eight participants with SCZ and cognitive impairment (measured via a set of executive functions tests) will be randomly allocated to receive either a single session of active (n = 24) or sham (n = 24) tDCS (20-min, 3-mA). The anodal and cathodal electrodes are positioned over the left and right DLPFC respectively. The stimulation occurs concurrently with the working memory task, which is initiated precisely 5 minutes after the onset of tDCS. Structural and resting-state (rs-fMRI) scans are conducted immediately before and after both active and sham tDCS using a 3 Tesla scanner (Siemens Prisma model) equipped with a 64-channel head coil. The primary outcome will be changes in brain activation (measures vis BOLD response) and working memory performance (accuracy, reaction time). DISCUSSION: The results of this study are helpful in optimizing tDCS protocols in SCZ and inform us of neurocognitive mechanisms underlying 3 mA stimulation. This study will additionally provide initial safety and efficacy data on a 3 mA tDCS protocol to support larger clinical trials. Positive results could lead to rapid and broader testing of a promising tool for debilitating symptoms that affect the majority of patients with SCZ. The results will be made available through publications in peer-reviewed journals and presentations at national and international conferences.

A real-world data analysis of electronic health records to investigate the associations of predominant negative symptoms with healthcare resource utilisation, costs and treatment patterns among patients with schizophrenia.

OBJECTIVES: Negative symptoms in schizophrenia are associated with significant illness burden. We sought to investigate clinical outcomes for patients with schizophrenia who present with predominant negative symptoms (PNS) vs without PNS. DESIGN: Retrospective analysis of electronic health record (EHR) data. SETTING: 25 US providers of mental healthcare. PARTICIPANTS: 4444 adults with schizophrenia receiving care between 1999 and 2020. EXPOSURE: PNS defined as ≥3 negative symptoms and ≤3 positive symptoms recorded in EHR data at the time of the first recorded schizophrenia diagnosis (index date). Symptom data were ascertained using natural language processing applied to semistructured free text records documenting the mental state examination. A matched sample (1:1) of patients without PNS was used to compare outcomes. Follow-up data were obtained up to 12 months following the index date. PRIMARY OUTCOME MEASURE: Mean number of psychiatric hospital admissions. SECONDARY OUTCOME MEASURES: Mean number of outpatient visits, estimated treatment costs, Clinical Global Impression - Severity score and antipsychotic treatments (12 months before and after index date). RESULTS: 360 (8%) patients had PNS and 4084 (92%) did not have PNS. Patients with PNS were younger (36.4 vs 39.7 years, p<0.001) with a greater prevalence of psychiatric comorbidities (schizoaffective disorders: 25.0 vs 18.4%, p=0.003; major depressive disorder: 17.8 vs 9.8%, p<0.001). During follow-up, patients with PNS had fewer days with an antipsychotic prescription (mean=111.8 vs 140.9 days, p<0.001). Compared with matched patients without PNS, patients with PNS were more likely to have a psychiatric inpatient hospitalisation (76.1% vs 59.7%, p<0.001) and had greater estimated inpatient costs ($16 893 vs $13 732, p=0.04). CONCLUSIONS: Patients with PNS were younger and presented with greater illness severity and more psychiatric comorbidities compared with patients without PNS. Our findings highlight an unmet need for novel therapeutic approaches to address negative symptoms to improve clinical outcomes.

Feasibility and effectiveness of a 24-weeks outdoor exercise program on the physical and mental health of persons with schizophrenia.

Outdoor exercise can be a novelty and effective therapeutic strategy to achieve positive physical and mental health outcomes in persons with schizophrenia. The aim of this study was to assess the feasibility and effectiveness of a 24-weeks outdoor exercise program in the physical and mental health of persons with schizophrenia. Fifty-two outpatients with schizophrenia were conveniently assigned to a 24-weeks walking/jogging combined with cycling outdoor program (n = 23, male = 14) or control group (n = 29, male = 20). Demographic and clinical measures were collected. Physical health was evaluated using anthropometric measures, 6 min walk test, Eurofit and accelerometer. Mental health was evaluated using self-esteem, motivation for exercise and quality of life questionnaires. Attendance rate to the outdoor program was 92 %. The exercise program significantly decreased participant's body mass index and improved functional exercise capacity and balance. No effects were reported in the self-esteem, motivation for physical activity and quality of life. Significant decreases were found in abdominal strength, hand grip and self-esteem levels of the control group. The outdoor exercise combining walking/jogging and cycling was an effective intervention to decrease body mass index and to improve physical fitness. It can be suggested as a therapeutic approach with an important impact on the management of schizophrenia.
