BACKGROUND: Bipolar disorder (BD) is a severe psychiatric disorder characterized by changes in mood that alternate between (hypo) mania or depression and mixed states, often associated with functional impairment and cognitive dysfunction. But little is known about biomarkers that contribute to the development and sustainment of cognitive deficits. The aim of this study was to review the association between neurocognition and biomarkers across different mood states. METHOD: Search databases were Web of Science, Scopus and PubMed. A systematic review was carried out following the PRISMA guidelines. Risk of bias was assessed with the Newcastle-Ottawa Scale. Studies were selected that focused on the correlation between neuroimaging, physiological, genetic or peripheral biomarkers and cognition in at least two phases of BD: depression, (hypo)mania, euthymia or mixed. PROSPERO Registration No.: CRD42023410782. RESULTS: A total of 1824 references were screened, identifying 1023 published articles, of which 336 were considered eligible. Only 16 provided information on the association between biomarkers and cognition in the different affective states of BD. The included studies found: (i) Differences in levels of total cholesterol and C reactive protein depending on mood state; (ii) There is no association found between cognition and peripheral biomarkers; (iii) Neuroimaging biomarkers highlighted hypoactivation of frontal areas as distinctive of acute state of BD; (iv) A deactivation failure has been reported in the ventromedial prefrontal cortex (vmPFC), potentially serving as a trait marker of BD. CONCLUSION: Only a few recent articles have investigated biomarker-cognition associations in BD mood phases. Our findings underline that there appear to be central regions involved in BD that are observed in all mood states. However, there appear to be underlying mechanisms of cognitive dysfunction that may vary across different mood states in BD. This review highlights the importance of standardizing the data and the assessment of cognition, as well as the need for biomarkers to help prevent acute symptomatic phases of the disease, and the associated functional and cognitive impairment.

BACKGROUND: This study investigates whether early clozapine use is associated with improved responses in different clinical domains, including positive and negative symptoms, functioning, and well-being. METHODS: Data from 254 clozapine-treated patients at Cambridgeshire and Peterborough NHS Foundation Trust (CPFT) were analysed. Among them, 231 (90.9 %) had a diagnosis of schizophrenia, 21 (8.3 %) schizoaffective disorder, and 2 (0.8 %) had other diagnoses. The International Classification of Diseases-Mortality and Morbidity Statistics criteria (ICD-10) were employed (World Health Organization, 1992). The cohort was assessed using the positive and negative syndrome scale (PANSS), the Brief Negative Symptom Scale (BNSS), Global Assessment of Functioning Scale (GAF), and the short version of Warwick-Edinburgh Mental Well-being Scale (SWEMWBS). Logistic regression models (for positive and negative symptom remission) and linear regression (for functioning and well-being) were utilized to assess the influence of time to clozapine initiation (TCI), age at the first episode of psychosis (AFE), duration of clozapine treatment (DCT), and gender. RESULTS: Early clozapine treatment (within the first three years after the first episode of psychosis) was associated with increased negative symptom remission (exp (B) = 0.38; p = 0.02) and higher functioning scores (ß = -0.12, p = 0.046). However, no effect of time to clozapine initiation was found on positive symptom remission rates or well-being scores. CONCLUSIONS: Initiating clozapine treatment within the first 3 years of the first episode of psychosis may lead to reduced severity of negative symptoms and improved functioning in clozapine-treated patients. The time to clozapine initiation did not influence its effect on positive symptom remission rates.

BACKGROUND: The treatment of schizophrenia requires a prolonged, multidimensional intervention that includes antipsychotic drugs. Treatment adherence is essential to effectively control the disorder. Shared decision-making (SDM) is a strategy, supported by numerous practical and ethical arguments, that seeks to involve patients in the therapeutic process to improve treatment adherence and satisfaction. The use of this model in mental health has been limited for many intrinsic and extrinsic reasons. The results of clinical trials conducted to date have largely been disappointing, potential due to study design-related limitations. AIM/QUESTION: To evaluate the efficacy, in terms of treatment adherence and improvement in clinical variables, such as severity of symptoms, days of hospitalization or insight, of a carefully timed SDM model initiated immediately prior to hospital discharge in patients with schizophrenia. METHODS: Single-blind, randomized clinical trial in an acute psychiatric care unit within the Andalusian Health Department to compare SDM (experimental group) to treatment as usual (TAU; control group) in a sample of patients hospitalized for an acute episode of schizophrenia or schizoaffective disorder. The study was performed between January 2014 and June 2017. The experimental group participated in SDM sessions prior to discharge with regular booster sessions over the one-year follow-up. The health care team responsible for SDM was predisposed to concordance (LatCon II scale) and received specific training in SDM. A hierarchical multiple linear regression analysis was performed to evaluate the factors independently associated with adherence, controlling for sociodemographic, clinical, and admission-related variables. Variables were assessed at admission, discharge and at 3, 6 and 12 months after discharge during the one year follow up. BARS, DAI, WAI-S, COMRADE and PANSS were used to evaluate adherence, attitude to treatment, therapeutic alliance, satisfaction and confidence with decision and clinical status, respectively. RESULTS: A total of 227 schizophrenic patients hospitalized with acute decompensation were evaluated; of these, 102 met all inclusion criteria and were included in the study. Most patients (95%) had prior experience with antipsychotics and most (82%) had experienced related side effects. Despite randomization, psychopathologic severity was greater in the experimental group, with a mean (SD) PANSS score of 104.08 (80) vs. 93.45 (20.30) (p < 0.05). The final regression model to explain adherence was significant (adjusted R2 = 0.384; F [df= 6] = 4.386; p < 0.001), with a direct, significant and independent association with SDM mediated by the number of booster sessions. DISCUSSION: Shared decision making with booster sessions appears to increase treatment adherence in patients with severe mental disorders. IMPLICATION ON PRACTICE: Ethical, practical, and clinical reasons support the use of strategies designed promote the use of long-term, shared decision-making in psychiatric patients, especially in schizophrenia spectrum disorder.

WHAT IS ALREADY KNOWN ABOUT THE TOPIC?: Our present understanding of mechanical restraint is heterogenous, largely due to the important differences between countries/regions. In Spain, the use of this restrictive practice is not regulated, nor is its use protocolized. Previous studies that have investigated the impact of organizational factors and changes in these protocols are often short and not conducted within a framework designed to establish a long-term plan for reducing the use of mechanical restraint. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: We demonstrate that the implementation of administrative and protocol changes in our psychiatric unit significantly reduced the use of mechanical restraint, thus laying the foundations for a regulatory framework. Our analysis shows that the profile of patients who require mechanical restraint is highly variable, but that certain clinical and institutional aspects within the framework of a long-term plan for the reduction in mechanical restraint can be targeted with long-lasting positive effects. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Organizational changes focussed on training staff, promoting family support and requiring the registration and close monitoring of episodes empower the role of the nursing staff in the prevention, monitoring and regulation of mechanical restraint. ABSTRACT: Introduction Mechanical restraint is a controversial restrictive practice to manage agitation or violent behaviour. Numerous studies have evaluated the factors and organizational changes that influence on mechanical restraint, but only for short time periods. None of those studies have assessed the effects of measures applied within the framework of a long-term plan to reduce the use of mechanical restraint. Given the lack of specific legislation in Spain, more data are required for its proper regulation. Aim/Question To evaluate the risk factors associated and the impact of specific measures designed to minimize the application of mechanical restraint in an acute mental health unit over an 8-year period and previous observation of 5 years. Methods Cross-sectional study based on a retrospective analysis of mechanical restraint records. We compared admissions requiring ≥one episode of restraint versus admissions not requiring this coercive measure. Results Between 2007 and 2014, 412 admissions (12%) required mechanical restraint. The data show that the measures applied in the previous five years had significantly reduced the total hours of restraint per semester. The factors associated with admissions requiring mechanical restraint were involuntary, unscheduled and longer admissions. The best predictor of restraint was involuntary admission (OR = 6.37), followed by the diagnosis of personality disorder (OR = 5.01). Discussion Identification of the factors associated with mechanical restraint would allow for early detection strategies. Our results provide additional evidence on the usefulness of organizational changes to reduce coercive measures, even in a country without specific legislation. Implications for Practice Organizational changes, such as staff training and increased family support during admission of episodes of mechanical restraint, can reduce the use of this measure. These measures also give the nursing staff greater responsibility in terms of their role in registering and monitoring the restrictive practice, thus helping to prevent or minimize the use of mechanical restraint.

OBJECTIVES: The aim of this study was to identify independent predictors of satisfaction with antipsychotics in patients with schizophrenia spectrum disorders treated in a mental health catchment area. METHODS: Observational analytical study of patients (n = 150) recruited through a convenience sampling method from five mental health units. Satisfaction with the antipsychotic as a medication was evaluated using the Treatment Satisfaction Questionnaire for Medication (TSQM). Therapeutic alliance was assessed by the Working Alliance Inventory Short Form (WAI-S). Patient-perceived participation in decision-making was assessed using COMRADE (Combined Outcome Measure for Risk communication And treatment Decision making Effectiveness). A multiple linear regression analysis was performed to identify variables independently associated with the TSQM 'Global Satisfaction' total score. RESULTS: Two variables - age and higher level of self-perceived participation in treatment decision-making - were directly, significantly, and independently associated (ß coefficient values: 0.209 and 0.432, respectively) with a higher TSQM Global satisfaction score. In addition, the severity of psychotic symptoms was inversely associated with satisfaction (ß coefficient value: -0.205) (R2 = 0.355; R2 adj. = 0.291; F(13) = 5.554; p < 0.01). CONCLUSIONS: These findings suggest that involving the patient in treatment decision-making and optimising the treatment to reduce symptoms, especially in younger patients, could increase satisfaction with antipsychotic treatment.Key PointsPatient involvement in shared decision-making is relevant for treatment satisfaction.Current evidence suggests that improving the doctor-patient relationship optimises antipsychotics outcomes.Self-perceived participation in decision-making predicts satisfaction with antipsychotic medication.Types of antipsychotics do not determine consistent differences in satisfaction.

OBJECTIVE: The aim of this paper is to provide evidence of the validity and reliability of the COMRADE scale (Combined Outcome Measure for Risk communication And treatment Decision making Effectiveness) in patients suffering from schizophrenia spectrum disorders. METHOD: 150 patients recruited at five mental health centers were assessed using a cross-sectional study design. The COMRADE, WAIS-S (therapeutic alliance) and TSQM (satisfaction with medication) scales were used. RESULTS: Exploratory Factor Analysis identified three factors from the COMRADE (F1: "Risk communication"; F2: "Confidence in decision" and F3: "Knowledge of decisional balance") which explain 45.2, 8.5 and 6% of the variance, respectively. Statistically significant correlations were observed between the scores of the COMRADE subscales with the subscales of the WAI-S and the TSQM. The internal consistency observed for each of the factorial scores of the COMRADE were (Cronbach's alpha values) 0.90, 0.89 and 0.74, respectively. CONCLUSION: The COMRADE scale offers appropriate psychometric properties for its use as a measure of perceived patient involvement in the shared decision making process in antipsychotic treatment. PRACTICE IMPLICATIONS: The use of the COMRADE measure in psychiatric clinical practice and in research studies provides an outcome measure of interventions from the shared decision making model.
