RESUMEN
BACKGROUND: The clinical debut of schizophrenia is frequently a first episode of psychosis (FEP). As such, there is considerable interest in identifying associations between biological markers and clinical or cognitive characteristics that help predict the progression and outcome of FEP patients. Previous studies showed that high prolactin, low oxytocin, and high homocysteine are factors associated with FEP 6 months after diagnosis, at which point plasma levels were correlated with some clinical and cognitive characteristics. METHODS: We reexamined 75 patients at 12 months after diagnosis to measure the evolution of these molecules and assess their association with clinical features. RESULTS: At follow-up, FEP patients had lower prolactin levels than at baseline, and patients treated with risperidone or paliperidone had higher prolactin levels than patients who received other antipsychotic agents. By contrast, no changes in oxytocin and homocysteine plasma levels were observed between the baseline and follow-up. In terms of clinical features, we found that plasma prolactin and homocysteine levels were correlated with the severity of the psychotic symptoms in male FEP patients, suggesting that they might be factors associated with psychotic symptomatology but only in men. Together with oxytocin, these molecules may also be related to sustained attention, verbal ability, and working memory cognitive domains in FEP patients. CONCLUSION: This study suggests that focusing on prolactin, oxytocin, and homocysteine at a FEP may help select adequate pharmacological treatments and develop new tools to improve the outcome of these patients, where sex should also be borne in mind.

BACKGROUND: Approximately 3% of the population suffers a first episode of psychosis (FEP), and a high percentage of these patients subsequently relapse. Because the clinical course following a FEP is hard to predict, it is of interest to identify cognitive and biological markers that will help improve the diagnosis, treatment, and outcome of such events and to define new therapeutic targets. Here we analyzed the plasma oxytocin and prolactin levels during an FEP, assessing their correlation with clinical and cognitive features. METHODS: The oxytocin and prolactin in plasma was measured in 120 FEP patients and 106 healthy controls, all of whom were subjected to a clinical and neuropsychological assessment. Most patients were under antipsychotics. Statistical analyses aimed to identify factors associated with the FEP and to search for associations between the variables. This study is preliminary and exploratory because the P-values were not corrected for multiple comparisons. RESULTS: FEP patients had less oxytocin, more prolactin, and a poor premorbid IQ, and they performed worse in sustained attention. Male patients with higher prolactin levels experienced more severe psychotic symptoms and required higher doses of antipsychotics. Low oxytocin was associated with poor sustained attention in women, whereas low oxytocin and high prolactin in men correlated with better performance in sustained attention. CONCLUSION: Low oxytocin, high prolactin, and poor premorbid IQ and sustained attention are factors associated with an FEP, representing potential therapeutic targets in these patients. These biological factors and cognitive domains might play an important role during a FEP, which could help us to develop new strategies that improve the outcomes of this disorder and that should perhaps be gender specific.

BACKGROUND: We report the psychometric properties of the Patient-Reported Impact of Symptoms in Schizophrenia Scale (PRISS), which assesses the impact of subjective experiences or qualia in outpatients with this condition. METHODS: A cross-sectional study was carried out in 162 patients diagnosed with schizophrenia in Spain. The PRISS measures the presence, frequency, concern and interference with daily life of self-reported experiences related to the main symptoms observed in these patients. The psychometric analysis included test-retest reliability, internal consistency and structural and convergent validity. RESULTS: The 28-item PRISS showed good test-retest reliability as 64.3% of the intraclass correlation coefficient values were between 0.40 and 0.79, which were statistically significant (p < 0.01). Analysis of the structural validity revealed a three-factor structure, (1) productive subjective experiences, (2) affective-negative subjective experiences and (3) excitation, which accounted for 56.11% of the variance. Of the Pearson's correlation coefficients analysed between the PRISS and the Positive and Negative Syndrome Scale (PANSS), Scale for Assessment of Negative Symptoms (SANS) and World Health Organization Disability Assessment Schedule (WHO-DAS), 72.2% were statistically significant (p < 0.05) and ranged from 0.38-0.42, 0.32-0.42 and 0.40-0.42, respectively. CONCLUSION: Our results indicate that the PRISS appears to be a brief, reliable and valid scale to measure subjective experiences in schizophrenia and provides valuable information complementary to clinical evaluation.

BACKGROUND: DESDE-LTC (Description and Evaluation of Services and DirectoriEs for Long-Term Care) is an international classification system that allows standardized coding and comparisons between different territories and care sectors, such as health and social care, in defined geographic areas. We adapted DESDE-LTC into a computer tool (DESDE-AND) for compiling a directory of care services in Andalucia, Spain. OBJECTIVE: The aim of this study was to evaluate the maturity of DESDE-AND. A secondary objective of this study is to show the practicality of a new combined set of standard evaluation tools for measuring the maturity of health technology products. METHODS: A system for semiautomated coding of service provision has been co-designed. A panel of 23 domain experts and a group of 68 end users participated in its maturity assessment that included its technology readiness level (TRL), usability, validity, adoption (Adoption Impact Ladder [AIL]), and overall degree of maturity [implementation maturity model [IMM]). We piloted the prototype in an urban environment (Seville, Spain). RESULTS: The prototype was demonstrated in an operational environment (TRL 7). Sixty-eight different care services were coded, generating fact sheets for each service and its geolocation map. The observed agreement was 90%, with moderate reliability. The tool was partially adopted by the regional government of Andalucia (Spain), reaching a level 5 in adoption (AIL) and a level 4 in maturity (IMM) and is ready for full implementation. CONCLUSIONS: DESDE-AND is a usable and manageable system for coding and compiling service directories and it can be used as a core module of decision support systems to guide planning in complex cross-sectoral areas such as combined social and health care.

BACKGROUND: There is evidence of negative attitudes among health professionals towards people with mental illness but there is also a knowledge gap on what training must be given to these health professionals during their education. The purpose of this study is to compare the attitudes of students of health sciences: nursing, medical, occupational therapy, and psychology. METHODS: A comparative and cross-sectional study in which 927 final-year students from health sciences university programmes were evaluated using the Mental Illness: Clinicians' Attitudes (both MICA-2 and MICA-4) scale. The sample was taken in six universities from Chile and Spain. RESULTS: We found consistent results indicating that stigma varies across university programmes. Medical and nursing students showed more negative attitudes than psychology and occupational therapy students in several stigma-related themes: recovery, dangerousness, uncomfortability, disclosure, and discriminatory behaviour. CONCLUSIONS: Our study presents a relevant description of the attitudes of each university programme for education against stigma in the formative years. Results show that the biomedical understanding of mental disorders can have negative effects on attitudes, and that education based on the psychosocial model allows a more holistic view of the person over the diagnosis.

BACKGROUND: Evidence from the context of local health ecosystems is highly relevant for research and policymaking to understand geographical variations in outcomes of health care delivery. In mental health systems, the analysis of context presents particular challenges related to their complexity and to methodological difficulties. Method guidelines and standard recommendations for conducting context analysis of local mental health care are urgently needed. This scoping study reviews current methods of context analysis in mental health systems to establish the parameters of research activity examining availability and capacity of care at the local level, and to identify any gaps in the literature. METHODS: A scoping review based on a systematic search of key databases was conducted for the period 2005-2016. A systems dynamics/complexity approach was adopted, using a modified version of Tansella and Thornicroft's matrix model of mental health care as the conceptual framework for our analysis. RESULTS: The lack of a specific terminology in the area meant that from 10,911 titles identified at the initial search, only 46 papers met inclusion criteria. Of these, 21 had serious methodological limitations. Fifteen papers did not use any kind of formal framework, and five of those did not describe their method. Units of analysis varied widely and across different levels of the system. Six instruments to describe service availability and capacity were identified, of which three had been psychometrically validated. A limitation was the exclusion of grey literature from the review. However, the imprecise nature of the terminology, and high number of initial results, makes the inclusion of grey literature not feasible. CONCLUSION: We identified that, in spite of its relevance, context studies in mental health services is a very limited research area. Few validated instruments are available. Methodological limitations in many papers mean that the particular challenges of mental health systems research such as system complexity, data availability and terminological variability are generally poorly addressed, presenting a barrier to valid system comparison. The modified Thornicroft and Tansella matrix and related ecological production of care model provide the main model for research within the area of health care ecosystems.

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.
RESUMEN
OBJECTIVE: This article reviews the usability of the Integrated Atlases of Mental Health as a decision support tool for service planning following a health ecosystem research approach. METHOD: This study describes the types of atlases and the procedure for their development. Atlases carried out in Spain are presented and their impact in mental health service planning is assessed. Atlases comprise information on the local characteristics of the health care system, geographical availability of resources collected with the DESDE-LTC instrument and their use. Atlases use geographic information systems and other visualisation tools. Atlases follow a bottom-up collaborative approach involving decision-makers from planning agencies for their development and external validation. RESULTS: Since 2005, Integrated Atlases of Mental Health have been developed for nine regions in Spain comprising over 65% of the Spanish inhabitants. The impact on service planning has been unequal for the different regions. Catalonia, Biscay and Gipuzkoa, and Andalusia reach the highest impact. In these areas, health advisors have been actively involved in their co-design and implementation in service planning. CONCLUSIONS: Atlases allow detecting care gaps and duplications in care provision; monitoring changes of the system over time, and carrying out national and international comparisons, efficiency modelling and benchmarking. The knowledge provided by atlases could be incorporated to decision support systems in order to support an efficient mental health service planning based on evidence-informed policy.

BACKGROUND: Evidence-informed planning and interpretation of research results both require standardised description of local care delivery context. Such context analysis descriptions should be comparable across regions and countries to allow benchmarking and organizational learning, and for research findings to be interpreted in context. The European Service Mapping Schedule (ESMS) is a classification of adult mental health services that was later adapted for the assessment of health and social systems research (Description and Evaluation of Services and DirectoriEs - DESDE). The aim of the study was to review the diffusion and use of the ESMS/DESDE system in health and social care and its impact in health policy and decision-making. METHOD: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (1997-2018). RESULTS: Out of 155 papers mentioning ESMS/DESDE, 71 have used it for service research and planning. The classification has been translated into eight languages and has been used by seven international research networks. Since 2000, it has originated 11 instruments for health system research with extensive analysis of their metric properties. The ESMS/DESDE coding system has been used in 585 catchment areas in 34 countries for description of services delivery at local, regional and national levels. CONCLUSIONS: The ESMS/DESDE system provides a common terminology, a classification of care services, and a set of tools allowing a variety of aims to be addressed in healthcare and health systems research. It facilitates comparisons across and within countries for evidence-informed planning.

OBJETIVO: Este artículo revisa y evalúa el uso de los Atlas Integrales de Salud Mental como herramientas de apoyo a la planificación de servicios dentro del modelo de investigación de ecosistemas de atención de salud. MÉTODO: Se describen los tipos de atlas y el procedimiento para su elaboración. Se presentan los realizados en España y se evalúa su impacto en la planificación de servicios de salud mental. Los atlas agregan información sobre las características locales del sistema de atención, la disponibilidad geográfica de recursos recogida mediante el instrumento DESDE-LTC, y su uso. Utilizan un sistema de información geográfica y otras herramientas visuales. Siguen una metodología de abajo arriba con colaboración de personas decisoras de agencias de planificación para su elaboración y validación externa. RESULTADOS: Desde 2005 se han realizado Atlas Integrales de Salud Mental en nueve comunidades autónomas que comprenden alrededor del 65% de la población de España. Los atlas han tenido un impacto desigual en la planificación de servicios, con un mayor impacto en Cataluña, Vizcaya y Guipúzcoa, y Andalucía, donde responsables sociales han participado activamente en su codiseño y su aplicación a la planificación de servicios sociosanitarios. CONCLUSIONES: Los atlas permiten detectar carencias o duplicidades en la atención, monitorizar cambios a lo largo del tiempo, realizar comparaciones nacionales e internacionales, modelar la eficiencia y hacer análisis benchmark. Este conocimiento puede incorporarse a los sistemas de apoyo a la decisión para una más eficaz planificación de los servicios de salud mental basada en evidencia informada

[ABSTRACT]. Objective. To describe the availability of local mental health (MH) services in small MH catchment areas in Central Chile, using a bottom-up approach. Methods. MH services of 19 small MH catchment areas in five health districts of Central Chile that provide health care to more than 4 million inhabitants were assessed using DESDELTC (Description and Evaluation of Services and Directories in Europe for Long-Term Care), a tool for standardized description and classification of LTC health services, in a study conducted in 2012 (“DESDE-Chile”) designed to complement other studies conducted in 2004 and 2012 at the national and regional level using the World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS). Key informants from national, regional, and local health authorities were contacted to compile a comprehensive list of MH services or facilities (health, social services, education, employment, and housing). The analysis of local care provision covered three criteria—service availability, placement capacity, and workforce capacity. Results. The study detected disparities in all three criteria (availability and placement and workforce capacity) across the five health districts, between urban and rural areas, and between neighboring urban areas. Analysis of service availability revealed differences in the weight of residential services versus day and outpatient care. The Talcahuano area could be considered a benchmark of MH care in Central Chile, based on its service provision patterns, and the criteria of the community care model. The list of MH services identified in this study differed from the one generated in the 2012 WHO-AIMS study. Conclusions. This survey of local MH service provision in small catchment areas using the DESDE-LTC tool provided MH service provision data that complemented information collected in other studies conducted at the national/regional level using the WHO-AIMS tool. The bottom-up approach applied in this study would also be useful for the assessment of equity and accessibility and local planning.
[RESUMEN]. Objetivo. Describir, usando un enfoque de abajo arriba, la disponibilidad de servicios locales de salud mental en las pequeñas áreas de captación de salud mental de la zona central de Chile. Métodos. En un estudio realizado en el 2012 (“DESDE-Chile”), se evaluaron los servicios de salud mental en 19 áreas pequeñas de captación de salud mental de cinco distritos de salud de la zona central de Chile que proporcionan atención de salud a más de 4 millones de habitantes utilizando DESDE-LTC (descripción y evaluación de servicios y guías en Europa para la atención a largo plazo), una herramienta para la descripción y la clasificación estandarizada de servicios de salud a largo plazo. Este estudio se diseñó para complementar otros estudios realizados en el 2004 y el 2012 a nivel nacional y regional usando el Instrumento de Evaluación para Sistemas de Salud Mental de la Organización Mundial de la Salud (IESM-OMS). Se contactó a informantes clave de las autoridades sanitarias nacionales, regionales y locales para compilar una lista integral de los servicios de salud mental o de los establecimientos (salud, servicios sociales, educación, empleo y vivienda). El análisis de la prestación de atención a nivel local abarcó tres criterios: disponibilidad de servicios, capacidad de colocación y capacidad de la fuerza laboral. Resultados. En el estudio se detectaron disparidades en los tres criterios (disponibilidad, y capacidad de colocación y de fuerza laboral) en los cinco distritos de salud, entre las zonas urbanas y rurales, y entre las zonas urbanas vecinas. El análisis de la disponibilidad de servicios mostró diferencias de peso entre los servicios residenciales y la atención ambulatoria y de día. El área de Talcahuano podría considerarse un punto de referencia para la atención de la salud mental en la zona central de Chile, por su modelo de prestación de servicios y los criterios del modelo de atención comunitaria. La lista de los servicios de salud detectados en este estudio es diferente de la que se generó en el estudio de IESM-OMS del 2012. Conclusiones. Esta encuesta sobre la prestación de servicios de salud mental a nivel local en áreas pequeña de captación usando la herramienta DESDE-LTC ha proporcionado datos sobre la prestación de servicios de salud mental que complementan la información recopilada en otros estudios realizados al nivel nacional y regional donde se usó la herramienta de IESM-OMS. El enfoque de abajo arriba que se aplicó en este estudio también podría ser útil para evaluar la equidad, la accesibilidad y la planificación local.
[RESUMO]. Objetivo. Descrever a disponibilidade de serviços locais de saúde mental em pequenas áreas de cobertura de saúde mental na região central do Chile com o uso de uma abordagem de baixo para cima (bottom-up). Métodos. Os serviços de saúde mental de 19 pequenas áreas de cobertura de saúde mental em cinco distritos de saúde da região central do Chile que prestam assistência de saúde a mais de 4 milhões de habitantes foram avaliados com o uso da ferramenta DESDE-LTC (Description and Evaluation of Services and Directories in Europe for Long-Term Care – descrição e avaliação de serviços e diretórios na Europa para atenção a longo prazo). Trata-se de uma ferramenta para descrição padronizada e classificação dos serviços de saúde de assistência de longo prazo. Os dados desta avaliação foram comparados aos de um estudo de 2012 (DESDE-Chile) realizado com a finalidade de complementar outros estudos conduzidos em 2004 e 2012 ao nível nacional e regional com o uso do Instrumento de Avaliação dos Sistemas de Saúde Mental da Organização Mundial da Saúde (WHO-AIMS). Neste estudo, foi solicitado aos informantes-chave das autoridades de saúde ao nível nacional, regional e local que fizessem uma relação completa dos serviços ou instituições de saúde mental (das áreas da saúde, assistência social, educação, trabalho e habitação). A prestação de assistência local foi analisada segundo três critérios: disponibilidade de serviços, capacidade de vagas e capacidade da força de trabalho. Resultados. O estudo verificou, nos cinco distritos de saúde, disparidades nos três critérios (disponibilidade e vagas e capacidade da força de trabalho) entre a zona urbana e rural e entre áreas urbanas vizinhas. A análise da disponibilidade de serviços revelou diferenças no peso entre os serviços residenciais e os serviços de assistência ambulatorial e atenção diária. Talcahuano poderia ser considerada a área de referência em atenção de saúde mental na região central do Chile, segundo os padrões de prestação de serviços e os critérios do modelo de atenção de base comunitária. A lista de serviços de saúde mental identificados no estudo difere da lista compilada no estudo de 2012 com o uso da WHO-AIMS. Conclusões. Esta pesquisa sobre a prestação local de serviços de saúde mental em pequenas áreas de cobertura com o uso da ferramenta DESDE-LTC proporcionou dados que complementaram os dados coletados em outros estudos realizados ao nível nacional e regional com o uso da ferramenta WHO-AIMS. A abordagem de baixo para cima empregada neste estudo também poderia ser útil na avaliação de equidade e acessibilidade e do planejamento local.
