First-episode psychosis intervention programme versus standard care for the clinical management of early phases of psychosis: cost analysis.

BACKGROUND: Early intervention programmes (EIPs) in psychosis have gained attention as specialised interventions to improve health-related and societal impacts for people with psychotic disorders. Previous studies have presented evidence in favour of EIPs over the first year of intervention, despite none considering the critical period before psychosis onset (5 years). AIMS: To compare the associated costs of the First Episode Psychosis Intervention Program (CRUPEP) and treatment as usual (TAU) in a real-world cohort in a non-specialised psychiatric community setting. METHOD: Direct and indirect mental health-related costs were calculated over 1 year and up to 7 years. Healthcare and societal costs were calculated from economic data related to the consumption of all healthcare resources, including emergency department attendances, hospital admissions, psychotropic medication prescriptions and societal costs. RESULTS: From a healthcare perspective, the intervention (CRUPEP) group initially showed a marginally higher cost per patient than the TAU group (€7621 TAU group v. €11 904 CRUPEP group) over the first year of follow-up. However, this difference was reversed between the groups on considering the entire follow-up, with the TAU group showing considerably higher associated costs per patient (€77 026 TAU v. €25 247 CRUPEP). CONCLUSIONS: The EIP (CRUPEP) showed clinical benefits and minimised the direct and indirect health-related costs of the management of psychosis. Although the CRUPEP intervention initially reported increased costs over 1 year, TAU surpassed the global costs over the entire follow-up.

Violence in first-episode psychosis: evidence from an early intervention in psychosis programme.

BACKGROUND: Psychotic disorders are frequently associated with a public perception of dangerousness and belligerence. This situation has contributed to the social stigmatisation of people with severe mental illness and the resulting discrimination that this scenario entails. Despite efforts to demystify such disorders, the association between violent behaviour and psychosis remains unclear. AIMS: To explore the incidence of the main types of violent offences in a cohort of patients presenting with first-episode psychosis (FEP). METHOD: Participants were recruited from the First Episode Psychosis Intervention Program (CRUPEP) cohort between 2009 and 2016. The main clinical variables were collected, including medical-forensic records of participants registered at the Basque Institute of Forensic Medicine (BIFM), to identify any violent acts in which participants were involved, either as victims or as offenders. RESULTS: Overall, 79.5% (n = 182) of the participants had no record of violent crime or offence recorded in the BIFM. Annual crime rates for the 2009-2016 period show a decreasing trend in both the general population (IRR = 0.981, 95% CI 0.978-0.983, P < 0.001) and in the FEP group (IRR = 0.019, 95% CI 0.012-0.028, P < 0.001); this pattern is more pronounced in the FEP group. Victimisation accounted for the vast majority of reported incidents; nevertheless, participants who had committed violent offences were mostly involved in intrafamily violence. CONCLUSIONS: Individuals with FEP were not involved in a higher number of crimes than the general population. The types of violent acts committed by people with FEP were heterogeneous, with extreme violence being particularly uncommon.

Gender differences in the management of acute psychiatric episodes in the emergency department: a cross-sectional analysis of the 2017-2019 triennium.

There is growing evidence that gender is an important determinant of mental health and well-being. In this sense, both biological and socio-economic factors play a key role in how people experience psychological disturbances. This study examine whether there were sex- and gender-based differences in the management of psychiatric disorders in the emergency department (ED). A cross-sectional retrospective study was conducted in the ED over the 2017-2019 period. Sex was codified as female/male and socio-economic deprivation index was compiled to address the impact of social determinants. Episodes were reclassified according to four major clusters. Psychotropic drug prescription was categorized according to the ATC classification. Poisson regression models, adjusted for age and socioeconomic status, were used. A total of 9789 episodes (53.9% females) of individuals who required an acute-related psychiatric intervention were retrieved. Age distribution and socioeconomic quintiles revealed gender differences. Anxiety-related consultations accounted for up to 50% of all episodes. Female gender was found to be overrepresented in anxiety and stress-related disorders, mood disorders, and personality disorders. In contrast, Males accounted for 70% of all psychoactive substance use disorders. Considering main clinical syndromic clusters, analysis showed that female patients were more likely to be prescribed with anxiolytic treatment in ED treatment than men in the categories of "Common mental disorders" (PR = 1.122 [1.014-1.242; p = 0.025), "Severe Mental Disorders" (PR = 1.217[1.054-1.406] p = 0.007) and "Personality disorders" (PR = 1.398 (1.038 - 1.884); p = 0.028). This study highlights the relevance of considering sex and gender as potential determinants in both the clinical presentation and management of psychiatric emergencies.

Neuropsychological and Functional Assessment of Cognitive Impairments in Schizophrenia.

Cognitive deficits are a central feature of psychotic disorders. Their impact and relevance for clinical prognosis and functional recovery, together with their usefulness in the development of novel therapeutic targets, have emphasized the role of cognition in the diagnosis and therapeutic management of schizophrenia. Here we describe the main aspects to consider before, during, and after the neuropsychological assessment of main cognitive domains affected in schizophrenia, from a research perspective toward clinical practice.

Clinical Management and Assessment of the Early Stages of Psychosis: A Multidimensional Approach.

Early intervention in psychosis has emerged as an integrated clinical and research strategy for the comprehensive care of people presenting with a first psychotic episode (FEP). In this sense, a multidisciplinary approach is essential for early detection and assessment of preliminary stages of the illness. The main objectives of early intervention programs include the implementation of specialized interventions aimed at promoting functional recovery and improving quality of life. In this chapter, we will describe the main advantages of specialized early intervention programs in psychosis. We will also describe the main aspects of assessment that need to be considered when approaching an FEP.

Isolation and Differentiation of Neurons and Glial Cells from Olfactory Epithelium in Living Subjects.

The study of psychiatric and neurological diseases requires the substrate in which the disorders occur, that is, the nervous tissue. Currently, several types of human bio-specimens are being used for research, including postmortem brains, cerebrospinal fluid, induced pluripotent stem (iPS) cells, and induced neuronal (iN) cells. However, these samples are far from providing a useful predictive, diagnostic, or prognostic biomarker. The olfactory epithelium is a region close to the brain that has received increased interest as a research tool for the study of brain mechanisms in complex neuropsychiatric and neurological diseases. The olfactory sensory neurons are replaced by neurogenesis throughout adult life from stem cells on the basement membrane. These stem cells are multipotent and can be propagated in neurospheres, proliferated in vitro and differentiated into multiple cell types including neurons and glia. For all these reasons, olfactory epithelium provides a unique resource for investigating neuronal molecular markers of neuropsychiatric and neurological diseases. Here, we describe the isolation and culture of human differentiated neurons and glial cells from olfactory epithelium of living subjects by an easy and non-invasive exfoliation method that may serve as a useful tool for the research in brain diseases.

Psychosis and substance abuse increase the COVID-19 mortality risk.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has been a global challenge. High mortality rates have been reported in some risk groups, including patients with pre-existing mental disorders. METHODS: We used electronic health records to retrospectively identify people infected due to COVID-19 (between March 2020 and March 2021) in the three territories of the Basque Country. COVID-19 cases were defined as individuals who had tested positive on a reverse transcription-polymerase chain reaction (PCR) test. Univariate and multivariate logistic regression models and multilevel analyses with generalized estimated equations were used to determine factors associated with COVID-19-related mortality and hospital admission. RESULTS: The COVID-19 mortality rate was increased for patients with psychotic disorders [odds ratio (OR) adjusted: 1.45, 95% confidence interval (CI) (1.09-1.94), p = 0.0114] and patients with substance abuse [OR adjusted: 1.88, 95% CI (1.13-3.14, p < 0.0152)]. The mortality rate was lower for patients with affective disorders [OR adjusted: 0.80, 95% CI (0.61-0.99), p = 0.0407]. Hospital admission rates due to COVID-19 were higher in psychosis [OR adjusted: 2.90, 95% CI (2.36-3.56), p < 0.0001] and anxiety disorder groups [OR adjusted: 1.54, 95% CI (1.37-1.72), p < 0.0001]. Among admitted patients, COVID-19 mortality rate was decreased for those with affective disorders rate [OR adjusted: 0.72, 95% CI (0.55-0.95), p = 0.0194]. CONCLUSIONS: COVID-19-related mortality and hospitalizations rates were higher for patients with a pre-existing psychotic disorder.

Negative symptoms and sex differences in first episode schizophrenia: What's their role in the functional outcome? A longitudinal study.

INTRODUCTION: Negative symptoms (NS) include asociality, avolition, anhedonia, alogia, and blunted affect and are linked to poor prognosis. It has been suggested that they reflect two different factors: diminished expression (EXP) (blunted affect and alogia) and amotivation/pleasure (MAP) (anhedonia, avolition, asociality). The aim of this article was to examine potential sex differences among first-episode schizophrenia (FES) patients and analyze sex-related predictors of two NS symptoms factors (EXP and MAP) and functional outcome. MATERIAL AND METHODS: Two hundred and twenty-three FES (71 females and 152 males) were included and evaluated at baseline, six-months and one-year. Repeated measures ANOVA was used to examine the effects of time and sex on NS and a multiple linear regression backward elimination was performed to predict NS factors (MAP-EXP) and functioning. RESULTS: Females showed fewer NS (p=0.031; Cohen's d=-0.312), especially those related to EXP (p=0.024; Cohen's d=-0.326) rather than MAP (p=0.086), than males. In both male and female group, worse premorbid adjustment and higher depressive symptoms made a significant contribution to the presence of higher deficits in EXP at one-year follow-up, while positive and depressive symptoms predicted alterations in MAP. Finally, in females, lower deficits in MAP and better premorbid adjustment predicted better functioning at one-year follow-up (R2=0.494; p<0.001), while only higher deficits in MAP predicted worse functioning in males (R2=0.088; p=0.012). CONCLUSIONS: Slightly sex differences have been found in this study. Our results lead us to consider that early interventions of NS, especially those focusing on motivation and pleasure symptoms, could improve functional outcomes.

Relation between EEG resting-state power and modulation of P300 task-related activity in theta band in schizophrenia.

There is some consistency in previous EEG findings that patients with schizophrenia have increased resting-state cortical activity. Furthermore, in previous work, we have provided evidence that there is a deficit in the modulation of bioelectrical activity during the performance of a P300 task in schizophrenia. Our hypothesis here is that a basal hyperactivation would be related with altered ability to change or modulate cortical activity during a cognitive task. However, no study so far, to the best of our knowledge, has studied the association between resting-state activity and task-related modulation. With this aim, we used a dual EEG paradigm (resting state and oddball task for elicitation of the P300 evoked potential) in a sample of patients with schizophrenia (n = 100), which included a subgroup of patients with first episode psychosis (n = 30), as well as a group of healthy controls (n = 93). The study measures were absolute power for resting-state; and spectral entropy (SE) and connectivity strength (CS) for P300-task data, whose modulation had been previously found to be altered in schizophrenia. Following the literature on P300, we focused our study on the theta frequency band. As expected, our results showed an increase in resting state activity and altered task-related modulation. Moreover, we found an inverse relationship between the amount of resting-state activity and modulation of task-related activity. Our results confirm our hypothesis and support the idea that a greater amount of resting theta-band synchrony could hamper the modulation of signal regularity (quantified by SE) and activity density (measured by CS) during the P300 task performance. This association was found in both patients and controls, suggesting the existence of a common mechanism and a possible ceiling effect in schizophrenia patients in relation to a decreased inhibitory function that limits their cortical reactivity to the task.

Gender-Based Analysis of the Psychological Impact of the COVID-19 Pandemic on Healthcare Workers in Spain.

Purpose: This study aims to analyze from a gender perspective the psychological distress experienced by the medical workforce during the peak of the pandemic in Spain. Methods: This is a single-center, observational analytic study. The study population comprised all associated health workers of the Cruces University Hospital, invited by email to participate in the survey. It consisted of a form covering demographic data, the general health questionnaire-28 (GHQ-28), and the perceived stress scale (PSS-14). We used multivariant regression analysis to check the effect of gender on the scores. We used gender analysis in both design and interpretation of data following SAGER guidelines. Results: Females made 74.6% of our sample, but their proportion was higher in lower-paid positions such as nursery (89.9%) than in higher-paid ones. The percentage of women categorized as cases with the GHQ-28 was 78.4%, a proportion significantly higher than in the male population (61.3%, p < 0.001). The multivariant regression analysis showed that being women, working as orderly hospital porters, and having a past psychiatric history were risk factors for higher scores in both the GHQ-28 and PSS-14. Conclusion: Women and those with lower-paid positions were at risk of higher psychological distress and worse quality of life within the medical workforce during the first wave of the pandemic. Gender analysis must be incorporated to analyze this fact better.

Characterization of dopamine D2 receptor coupling to G proteins in postmortem brain of subjects with schizophrenia.

BACKGROUND: Alterations of dopamine D1 (D1R) and D2 receptor (D2R) are proposed in schizophrenia but brain neuroimaging and postmortem studies have shown controversial results in relation to D1R and D2R density. Besides, scarce information on the functionality of brain D1R and D2R is available. The present study characterized G-protein activation by D1R and D2R agonists in postmortem human brain. Furthermore, D2R functional status was compared between schizophrenia and control subjects. METHODS: G-protein receptor coupling was assessed in control caudate nucleus and frontal cortex by [35S]GTPγS-binding stimulation induced by increasing concentrations (10-10-10-3 M) of dopamine, and the selective dopaminergic agonists SKF38393 (D1R) and NPA (D2R). Concentration-response curves to NPA stimulation of [35S]GTPγS binding were analyzed in antipsychotic-free (n = 10) and antipsychotic-treated (n = 7) schizophrenia subjects and matched controls (n = 17). RESULTS: In caudate, [35S]GTPγS-binding responses to agonists were compatible with the existence of functional D2R. In contrast, stimulations in cortex showed responses that did not correspond to D1R or D2R. [35S]GTPγS-binding activation by NPA in caudate displayed biphasic curves with similar profile in schizophrenia (EC50H = 7.94 nM; EC50L = 7.08 µM) and control (EC50H = 7.24 nM; EC50L = 15.14 µM) subjects. The presence or absence of antipsychotic medication did not influence the pharmacological parameters. CONCLUSIONS: Feasibility of functional evaluation of dopamine receptors in postmortem human brain by conventional [35S]GTPγS-binding assays appears to be restricted to signalling through inhibitory Gi/o proteins. These findings provide functional information about brain D2R status in subjects with schizophrenia and do not support the existence of D2R supersensitive in this mental disorder.

Cognitive Enhancers in Schizophrenia: A Systematic Review and Meta-Analysis of Alpha-7 Nicotinic Acetylcholine Receptor Agonists for Cognitive Deficits and Negative Symptoms.

Background: Schizophrenia is a severe and enduring disease and is one of the leading causes of disability worldwide. Cognitive impairment is a core clinical symptom that plays a crucial role in functional outcomes and prognosis, thus making it a relevant treatment target. The aim of this study was to assess the efficacy of alpha-7 nicotinic acetylcholine receptor agonists (α7 nAChR) as adjunctive treatment to enhance cognition and ameliorate negative symptoms in patients with schizophrenia. Methods: A search strategy was developed for MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials up to May 2019. We included randomized controlled trials (RCTs) that compared antipsychotic treatment plus α7 nAChR agonists with antipsychotic treatment plus placebo and determined their effects on the main cognitive domains proposed by the MATRICS initiative and on negative symptoms. Two authors independently reviewed study eligibility and data extraction and assessed the risk of bias of the studies included. According to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework, we used a random-effects model and assessed the quality of the evidence. Results: Thirteen studies were included in the quantitative analysis. No differences were found in any of the cognitive domains assessed in four RCTs (n = 414). In contrast, nine RCTs (n = 978) presented a small effect in support of α7 nAChR agonists for negative symptoms [standardized mean difference -0.28, 95% CI (-0.56 to -0.00); P = 0.05], even though the confidence to support this evidence is low according to the GRADE system. Conclusions: Current evidence is too weak to consider α7 nAChR agonists as an effective add-on treatment to antipsychotics to enhance cognition and negative symptoms.

Long-acting injectable aripiprazole in pregnant women with schizophrenia: a case-series report.

Antipsychotic long-acting formulations (LAI-AP) have emerged as a new therapeutic choice to treat patients presenting a severe mental disorder. Despite that, to date, there is a lack of safety data and studies regarding the use of LAI-AP formulations in pregnant women. Here we present the first six-case series of pregnant women with schizophrenia treated with aripiprazole-LAI reported in the literature. All patients remained psychopathologically stable through pregnancy and the postpartum period, and all of them were in treatment with aripiprazole-LAI. To date, all infants remain healthy with normal developmental milestones, without the presence of congenital malformations or adverse effects. Lack of information on safety data regarding the use of new antipsychotic formulations remains important in treating women with mental illness who desire to become pregnant. Further studies in this clinical population with a larger number of patients included remains necessary.

Antipsicóticos inyectables de liberación prolongada para el tratamiento de la esquizofrenia en España / Long-acting injectable antipsychotics for the treatment of schizophrenia in Spain

Los antipsicóticos son un componente esencial del tratamiento de la esquizofrenia. Las formulaciones inyectables de liberación prolongada (ILP) surgen para mejorar la adherencia con el potencial asociado de reducir el riesgo de recaídas. El objetivo de este artículo es analizar el uso de antipsicóticos ILP en España -que es similar al de otros países europeos pero con un predominio de la utilización de ILP de segunda generación-, discutir las posibles causas de las diferencias de prescripción respecto a otros países de nuestro entorno (entre otras, aspectos organizativos, actitudes de psiquiatras, pacientes y familiares, guías de práctica clínica), y discutir su utilización en unidades de agudos, primeros episodios, y en niños y adolescentes. A nuestro juicio, aunque es necesario aumentar las pruebas existentes respecto a las ventajas de los antipsicóticos ILP y la diferenciación entre aquellos disponibles actualmente, su utilización seguirá probablemente creciendo impulsada por la experiencia clínica

Antipsychotics are an essential component in the treatment of schizophrenia. Long-acting injectable formulations (LAI) arose to improve adherence with the associated potential of reducing the risk of relapse. The objective of this article is to analyze the use of LAI antipsychotics in Spain, which is similar to other European countries but with a predominance of the use of second generation LAI, to discuss the possible causes of prescribing differences with respect to other countries (including organizational aspects, attitudes of psychiatrists, patients and family members, and clinical practice guidelines), and to discuss their use in acute psychiatric units, first episode, and in children and adolescents. In our view, while it is necessary to increase existing evidence regarding the advantages of LAI antipsychotics and the differentiation between LAI antipsychotics currently available, their use will likely continue to grow driven by clinical experience

Long-acting injectable second-generation antipsychotics in first-episode psychosis: a narrative review.

Long-acting injectable (LAI) antipsychotics could be a favorable option of treatment and have some advantages over oral medications. The aim of this study was to review the published data on the use of LAI formulation of second-generation antipsychotics (SGA) in first-episode psychosis (FEP). Using PubMed and Scopus databases, we performed a systematic literature search of articles published between 1 January 2000 and 30 April 2018, that reported clinical trials on the use of LAI SGAs in patients with FEP. Seventy-seven articles were considered eligible and full-text revised. Five studies fulfilled the inclusion criteria and evaluated the effect of LAI risperidone in FEP patients. Treatment with LAI SGAs was well accepted, and the majority of FEP patients agreed to change from an oral to an injectable formulation. At the 12-month follow-up, between 68 and 95% of FEP patients treated with LAI risperidone showed a good clinical response and 64% achieved remission of symptoms for at least 24 months of follow-up. Treatment with LAI SGAs can offer significant advantages over oral antipsychotics to FEP patients, especially to improve the adherence to medication and prevent the worsening of symptoms, the relapse, and rehospitalization associated with the discontinuation of treatment.

Transexualidades de hombre a mujer / Transsexualité d’homme à femme / Male to female transsexualities

El propósito de este trabajo es intentar comprender más profundamente cómo se llega a la transexualidad de hombre a mujer. Presenta una discusión psicoanalítica sobre un estudio controlado de dos grupos: uno de 25 transexuales de hombre a mujer y el otro, de 25 controles, con sexo masculino e identidad de género masculina. Se estudian variables relacionadas con las representaciones de sus familias de la primera infancia. En la muestra de transexuales, la figura paterna se percibe como más negligente, las madres y los padres como más sobreprotectores e intrusivos, y los sujetos se ubican más cerca de sus madres y lejos de sus padres que en la muestra de los controles. Un tercio de la muestra de transexuales han recibido tamiento hormonal y cirugía completa de reasignación y aproximadamente un tercio presenta pechos femeninos, pero mantiene los genitales masculinos. Los resultados del estudio se discuten utilizando la teoría freudiana de las identificaciones: identificación primaria, narcisista e histérica. Dichos procesos de identificación se proponen como posibles vías para el establecimiento de una identidad de género divergente del sexo biológico. (AU)

The purpose of this work is to more deeply understand how male to female transsexualism occurs. It presents a psychoanalytic discussion on a controlled study of two sample groups, one of 25 adult male to female transsexuals and cohort control of 25 people of male sex and male gender identity. The variables related to these people’s representations of their early childhood families are studied. In the transsexual sample, the father figure is perceived as more negligent, the mothers and fathers as overprotective and intrusive, and the people remember being much closer to their mothers. One third of the transsexual sample has undergone total reassignment and approximately one third present female breasts but maintain male genitals. The results of the study are discussed using Freudian identification theory: primary, narcissistic, and hysterical identification. Said identification processes are proposed as channels of influence for the establishment of gender identity separate from biological factors. (AU)

Le propos de ce travail est d’essayer de comprendre plus profondément comment on arrive à la transsexualité d’homme à femme. Il présente une discussion psychanalytique sur une étude contrôlée de deux groupes : un de 15 transsexuels d’homme à femme et un autre, de 25 contrôles, de sexe masculin et identité de genre masculin. L’on étudie des variables aux représentations de leurs familles de la petite enfance. Dans l´échantillon des transsexuels, la figure paternelle est perçue comme plus négligente, les mères et les pères sont plus surprotecteurs et intrusifs, et les sujets se situent plus près de leurs mères et plus loin de leurs pères que dans l´échantillon de contrôle. Un tiers de l´échantillon de transsexuels a reçu un traitement hormonal et une chirurgie complète de réaffectation et environ un tiers présente des seins féminins, mais maintiennent les génitaux masculins. Les résultats de l’étude sont discutés en utilisant la théorie freudienne des identifications : identification primaire, narcissique et hystérique. Ces processus d’identification sont proposés comme des chemins possibles pour l’établissement d’une identité de genre divergeant du sexe biologique. (AU)

Cognitive Impairment in Patients With Neuropsychiatric and Non-neuropsychiatric Systemic Lupus Erythematosus: A Systematic Review and Meta-analysis.

OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. Its most prevalent manifestation is neuropsychiatric SLE (NP-SLE), which is characterized by increased involvement of the nervous system, with relevant symptoms, such as marked cognitive deficits, which are directly involved in subsequent functional disability. The objective of this study is to identify and compare the profile of cognitive deficits in patients with NP-SLE and patients with non-neuropsychiatric SLE (nonNP-SLE) by means of a systematic review and meta-analysis. METHODS: We performed a systematic literature search based on the key words "cogn* OR neurocogn* AND lupus AND neuropsychiatry*" and included articles published between April 1999 and December 2016. A total of 244 articles were retrieved. We excluded reviews and meta-analyses, experiments not performed in humans, and single case reports. We included studies that used standardized cognitive measures and had included at least the subgroups NP-SLE and non NP-SLE. RESULTS: The meta-analysis was finally based on six studies, and 10 neuropsychological variables were examined. Significant differences were observed between the groups for six variables. In the remaining four variables, we observed marked heterogeneity between the groups or a low number of studies. CONCLUSIONS: The data obtained indicate greater cognitive impairment among NP-SLE patients than among nonNP-SLE patients, at least for the cognitive domains of visuomotor coordination, attention, executive function, visual learning and memory, and phonetic fluency. The identification and definition of cognitive deficits in SLE patients is necessary to develop adequate cognitive remediation programs to improve functional outcomes. (JINS, 2018, 24, 629-639).
