RESUMO
PURPOSE: Previous studies have investigated the role of gender in clinical symptoms, social functioning, and neuropsychological performance in people with first-episode psychosis (FEP). However, the evidence of gender differences for metacognition in subjects with FEP is still limited and controversial. The aim of the present study was to explore gender differences in cognitive insight and cognitive biases in this population. METHODS: Cross-sectional study was carried out in a sample of 104 patients with FEP (35 females and 69 males) recruited from mental health services. Symptoms were assessed with the Positive and Negative Syndrome Scale, cognitive insight with the Beck Cognitive Insight Scale, and cognitive bias by the Cognitive Biases Questionnaire for Psychosis. The assessment also included clinical and sociodemographic characteristics. RESULTS: After controlling for potential confounders (level of education, marital status, and duration of psychotic illness) analysis of covariance revealed that males presented greater self-reflectiveness (p = 0.004) when compared to females. However, no significant differences were found in self-certainty and composite index of the cognitive insight scale, as in the cognitive biases assessed. CONCLUSIONS: Gender was an independent influence factor for self-reflectiveness, being better for males. Self-reflectiveness, if shown to be relatively lacking in women, could contribute to the design of more gender-sensitive and effective psychotherapeutic treatments, as being able to self-reflect predicts to better treatment response in psychosis.
RESUMO
INTRODUCTION: Insight in psychosis has been conceptualized as a continuous, dynamic, and multidimensional phenomenon. This study aims to determine the impact of delusions and hallucinations in different dimensions of clinical insight in schizophrenia spectrum disorders. METHODS: Cross-sectional multicenter study including 516 patients (336 men) diagnosed with schizophrenia spectrum disorders. Based on dichotomized scores of Positive and Negative Syndrome Scale (PANSS) items P1 (delusions) and P3 (hallucinations), patients were assigned to four groups according to current clear presence of delusions (scores 4 or above 4 in PANSS item P1) and/or hallucinations (scores 4 or above 4 in PANNS item P3). Insight was assessed using the three main dimensions of the Scale of Unawareness of Mental Disorder (SUMD). RESULTS: Around 40% of patients showed unawareness of illness; 30% unawareness of the need for treatment; and 45% unawareness of the social consequences of the disorder. Patients with current clear presence of delusions had higher overall lack of awareness, regardless of current clear presence of hallucinations. Similarly, the clear presence of delusions showed a greater predictive value on insight than the presence of hallucinations, although the implication of both in the prediction was modest. CONCLUSIONS: Our results confirm that lack of insight is highly prevalent in schizophrenia spectrum disorders, particularly when patients experience delusions. This study adds insight-related data to the growing symptom-based research, where specific types of psychotic experiences such as hallucinations and delusions could form different psychopathological patterns, linking the phenomenology of delusions to a lack of clinical insight.
RESUMO
Stressful life events (SLE) tend to occur before the onset of psychosis, this highlights the importance of its detection and evaluation in these patients. The need to have instruments that assess SLE easily and quickly underpins the objective of this study, which is to validate a short version of the questionnaire of stressful life events (QSLE). 124 patients with first-episode psychosis and 218 healthy controls aged between 11 and 52 years were recruited. The QSLE scale underwent discrimination analysis, which revealed 18 items had good SLEs discriminability between the two samples. These 18 items were then used to create the shorter QSLE-SV. The QSLE-SV showed good internal consistency (Cronbach's alpha = 0.749). An AUC of 0.830 was observed, suggesting that the predictor was good. Using 2 as the cut-off score to predict an individual as a patient would yield a sensitivity of 91.1% and a specificity of 51.6%, and using a cut-off point of 3, the sensitivity was 77.4% and the specificity was 72.5%. QSLE-SV displayed satisfactory psychometric properties in a Spanish population. The QSLE-SV allows for investigating childhood, adolescent and adult life events by measuring current stress and age on a continuous scale in a quick and easy way.

The onset of first episode psychosis (FEP) is a period of increased risk of suicide, which is 60% higher than in other stages of the disease. This work explored suicidal behaviour and its most relevant factors in a population with FEP and a healthy control (HC) sample. We used the Suicide Risk Scale of Plutchik (SRSP) to assess suicide behaviour, and Calgary Depression Scale for Schizophrenia (CDSS), Young Mania Rating Scale (YMRS), Personal and Social Performance Scale (PSP), Perceived Stress Scale (PSS) and Positive and Negative Syndrome Scale (PANSS) were administered to assess the severity of depression, mania, psychosocial functioning, perceived stress and psychopathology, respectively. Patients with FEP showed a higher prevalence in all measures of suicide behaviour than HC. Younger age and depressive symptoms were the most important predictors of suicide ideation and suicide attempt. More perceived stress and higher hopelessness were the most relevant predictors of suicide risk. Symptoms did not appear to be important factors in suicide behaviour. Younger age, perceived stress and depressive symptoms seem to be the most important factors in suicide behaviours in FEP.

The importance of depression in adult people with first-episode psychosis (FEP) has been demonstrated. However, it has hardly been studied in children and adolescents. There is a need to broaden knowledge of the relationship between psychotic symptoms and specific depression symptomatology. The aims of study were (a) to examine the frequency of presence and type of depressive symptoms in early onset FEP, and (b) to assess the relationship between depressive symptoms and psychotic symptomatology, and specifically negative symptoms. An observational cross-sectional study was performed in 62 FEP cases. Inclusion criteria were two or more psychotic symptoms, age 7-17 years old, first mental health service consultation, and fewer than 6 months from the first contact with the service. Participants were assessed with clinical and socio-demographic questionnaires: the Positive and Negative Syndrome Scale (PANSS) and the Children Depression Inventory (CDI). A Student t test was performed to compare psychotic symptoms in both groups: presence of depression and the absence of depression. A Pearson correlation was performed in order to relate subscales of the PANSS and each of the depression subscales and factors, as well the relation between negative and depressive symptoms. Our results show that a high percentage of people with an early onset of a FEP scored positively for depression. The most prevalent depressive symptoms were associated with schooling. The presence of depression was associated with negative, affective, and excited symptoms. Self-esteem, school problems, negative affect, and biological dysregulation were associated with psychotic symptoms. Finally, depressive items related to social functioning were more closely associated with negative symptoms of the PANSS. In conclusion, owing to the high incidence of depression in FEP in those suffering early onset of psychosis, there is a need for instruments to measure the depression more specifically in children and adolescent, and to uncover the clinical characteristics of depression in this population.

Facial emotion recognition is considered the foundation of effective social functioning, but it has been found impaired in several clinical populations. How- ever, there are few validated tests to measure the ability. To the best of our knowledge, there is no validated measure in a Spanish population. We translated and validated Baron Cohen’s Face Test in a general Spanish population.

We assessed the utility of raloxifene (60 mg/day) as an adjuvant treatment for cognitive symptoms in postmenopausal women with schizophrenia in a 24-week, double-blind, randomized, placebo-controlled study. Patients were recruited from the inpatient and outpatient services of Parc Sanitari Sant Joan de Déu, Hospital Universitari Institut Pere Mata, and Corporació Sanitària Parc Taulí. Seventy eight postmenopausal women with schizophrenia were randomized to either adjunctive raloxifene or placebo. Sixty-eight began the clinical trial (37 women on raloxifene adjunct) and 31 on placebo adjunct. The outcome measures were: memory, attention and executive function. Assessment was conducted at baseline and at week 24. Between groups homogeneity was tested with the Student's t test for continuous variables and/or the Mann-Whitney U test for ordinal variables and the χ2 test or Fisher's exact test for categorical variables. The differences between the two groups in neuropsychological test scores were compared using the Student's t test. The sample was homogenous with respect to age, formal education, illness duration and previous pharmacological treatment. The addition of raloxifene to antipsychotic treatment as usual showed no differences in cognitive function. The daily use of 60 mg raloxifene as an adjuvant treatment in postmenopausal women with schizophrenia has no appreciable effect.ClinicalTrials.gov Identifier: NCT01573637.

To model the influence of psychopathology on insight deficits in schizophrenia spectrum patients with a gender-stratified analysis. Five hundred sixteen patients (65.1% men) with schizophrenia spectrum disorders were evaluated in four centres of the metropolitan area of Barcelona (Catalonia). Psychopathological assessment was performed using different PANSS factors. Insight and its three main dimensions were assessed by means of the Scale of Unawareness of Mental Disorder: awareness of the disease (SUMD-1), of the effect of medication (SUMD-2) and of the social consequences of the disease (SUMD-3). Structural equation models (SEMs) were used to fix the model in the total sample and by gender. Additional analyses included age, duration of illness (DOI) and education status (ES). There were no significant differences between men and women in the three main dimensions of insight. The SEMs in the total sample showed a modest fitting capacity. Fitting improved after a gender-stratified analysis (particularly in women). In men, positive and excited symptoms were associated with poorer insight in all SUMD dimensions, whereas depressive symptoms were associated with better insight. ES in men was also associated with better SUMD-2 or SUMD-3. In contrast, in women, symptoms did not have a negative effect on SUMD-1 or SUMD-2. However, positive symptoms were associated with a poorer SUMD-3, whereas depressive symptoms were associated with better SUMD-3. Moreover, education level was also associated with a better SUMD-3. A gender approach improved the comprehension of the model, supporting the relevance of gender analysis in the study of insight.

Accumulating evidence suggests that Specificity Protein 1 (SP1) and 4 (SP4) transcription factors are involved in the pathophysiology of schizophrenia. The therapeutic use of selective oestrogen modulators such as raloxifene added to antipsychotic drugs in the treatment of postmenopausal women with schizophrenia has been investigated in a few clinical trials, which reported an improvement in negative, positive, and general psychopathological symptoms. We aimed to investigate the possible association between peripheral SP protein levels and symptom improvement in postmenopausal women with schizophrenia treated with adjuvant raloxifene. In a subgroup of 14 postmenopausal women with schizophrenia from a 24-week, randomized, parallel, double-blind, placebo-controlled clinical trial (NCT015736370), we investigated changes in SP1 and SP4 protein levels in peripheral blood mononuclear cells. Participants were randomized to either 60 mg/day adjunctive raloxifene or placebo. Psychopathological symptoms were assessed at baseline and at week 24 with the Positive and Negative Syndrome Scale (PANSS). The expression of SP proteins was evaluated by immunoblot, and changes in PANSS scores and protein levels were compared at baseline and after 24 weeks of treatment. An improvement in symptoms was observed in the intervention group, but not in placebo group. Post-treatment protein levels of SP4, but not SP1, correlated with improvements in general and total PANSS subscales in the raloxifene intervention group. A reduction in SP4 levels was found after raloxifene treatment. These results suggest that SP4 may be involved in raloxifene symptom improvement in postmenopausal women and could be a potential candidate for future studies investigating blood-based biomarkers for raloxifene effectiveness.

Hallucinations have been found to be associated with various types of source memory failure in both schizophrenia patients and hallucination-prone healthy individuals. We investigated the associations of clinical and non-clinical hallucinations with source memory errors in a visual memory task that involved the remembering of picture presentation context. 59 schizophrenia patients and 61 healthy individuals took part in the study. Pictures were presented either at different locations or in association with different visual stimuli. The participants were required afterwards to recognize the target pictures among distractors, and then to remember their spatial location or the visual stimulus that was associated with them. Liberal response bias in picture recognition was associated with hallucination proneness and auditory-verbal hallucinations in subsamples of participants with significant non-clinical or clinical hallucinations. After controlling for overall memory performance, failure to remember the spatial location of the pictures was associated with visual hallucinations in male patients; failure to remember the associated visual stimulus was related to auditory-verbal hallucinations in female patients and to hallucination proneness in healthy women. The findings suggest that both clinical and non-clinical hallucinations are associated with loss of contextual information relative to the acquisition of events.

BACKGROUND: Cognitive deficits are a core feature of early stages in schizophrenia. However, the extent to which antipsychotic (AP) have a deleterious effect on cognitive performance remains under debate. We aim to investigate whether anticholinergic loadings and dose of AP drugs in first episode of psychosis (FEP) in advanced phase of remission are associated with cognitive impairment and the differences between premorbid intellectual quotient (IQ) subgroups. METHODS: Two hundred and sixty-six patients participated. The primary outcomes were cognitive dimensions, dopaminergic/anticholinergic load of AP [in chlorpromazine equivalents (Eq-CPZ) and the Anticholinergic Risk Scale (ARS), respectively]. RESULTS: Impairments in processing speed, verbal memory and global cognition were significantly associated with high Eq-CPZ and verbal impairment with high ARS score. Moreover, this effect was higher in the low IQ subgroup. CONCLUSIONS: Clinicians should be aware of the potential cognitive impairment associated with AP in advanced remission FEP, particularly in lower premorbid IQ patients.

Alcohol use disorders (AUD) are 2 times higher among psychiatric patients than in the general population. The under-recognition of this dual diagnosis can entail several negative outcomes. Early assessment with a screening tool like the CAGE questionnaire could be an opportunity to improve patients' prognoses. The objective of this study is to assess AUD risk in an outpatient psychiatric sample with a modified CAGE, considering the influence of age, gender and clinical psychiatric diagnosis. An observational, multicentric, descriptive study was carried out. The 4-item CAGE scale, camouflaged in a healthy lifestyle questionnaire, was implemented, using a cut-off point of one. 559 outpatients were assessed. 54% were female and the average age was 50.07 years. 182 patients presented a CAGE score ≥1 (45.1% of men and 21.9% of women). Gender was the strongest predictor of a positive result in CAGE, as men were 3.03 times more likely to score ≥1 on the CAGE questionnaire (p < .001, 95% CI: 0.22-0.49). Patients with bipolar and personality disorders had the highest rates of CAGE scores ≥1 (45.2 and 44.9%, respectively), with a significant association between diagnosis and a positive score (p = .002). Patients above 60 years were 2.5 times less likely to score ≥1 on the CAGE (p = .017, 95% CI: 0.19-0.85). Specific screening questionnaires, like the CAGE scale, can be an easy and useful tool in the assessment of AUD risk in psychiatric outpatients. Male patients with a bipolar or personality disorder present a higher risk of AUD.
Los trastornos por uso de alcohol (TUA) son 2 veces más frecuentes en pacientes psiquiátricos que en la población general. El infradiagnóstico de patología dual puede tener diversas consecuencias negativas; una valoración precoz con herramientas de cribaje como la escala CAGE podría mejorar el pronóstico de estos pacientes. El objetivo de este estudio es valorar el riesgo de TUA en pacientes psiquiátricos ambulatorios con una CAGE modificada, considerando la influencia de edad, género, y diagnóstico psiquiátrico. Se realizó un estudio descriptivo observacional, multicéntrico. La escala CAGE de 4 ítems, camuflada en un cuestionario de vida saludable, se aplicó utilizando el punto de corte de 1. Se valoraron 559 pacientes. El 54% eran mujeres, y la edad media fue de 50,07 años. 182 pacientes presentaron una puntuación ≥1 (45,1% de los hombres y 21,9% de las mujeres). El género fue el predictor principal de un resultado positivo en la escala CAGE, siendo 3,03 veces más probable que los hombres obtengan una puntuación ≥1 (p < ,001, 95% IC: 0,22-0,49). El trastorno bipolar y los trastornos de personalidad presentaron las tasas más altas de puntuaciones ≥1 (45,2 y 44,9%, respectivamente) con una asociación significativa entre diagnóstico y un resultado positivo (p = ,002). Los pacientes de más de 60 años mostraron 2,5 veces menos probabilidades de obtener una puntuación positiva (p = ,017, 95% IC: 0,19-0,85). Cuestionarios específicos, como CAGE, pueden ser herramientas sencillas y útiles para valorar el riesgo de TUA en pacientes psiquiátricos ambulatorios. Los pacientes hombres con trastorno bipolar o de personalidad presentan un riesgo más elevado de TUA.

BACKGROUND: Despite the theoretical potential of m-health solutions in the treatment of patients with schizophrenia, there remains a lack of technological solutions in daily practice. The aim of this study was to measure the receptivity of patients, informal carers, and clinicians to an integral intervention model focused on patients with persistent positive symptoms: Mobile Therapeutic Attention for Patients with Treatment Resistant Schizophrenia (m-RESIST). METHODS: A qualitative study of the needs and acceptability of outpatients with treatment-resistant schizophrenia was carried out in Parc Sanitari Sant Joan de Déu (Barcelona). We analyzed the opinions of patients, informal carers, and clinicians concerning the services initially thought to be part of the solution. Five focus groups and eight interviews were carried out, using discourse analysis as the analytical approach. RESULTS: A webpage and a virtual forum were perceived as suitable to get reliable information on both the disease and support. Data transmission service, online visits, and instant messages were evaluated as ways to improve contact with clinicians. Alerts were appreciated as reminders of daily tasks and medical appointments. Avoiding stressful situations for outpatients, promoting an active role in the management of the disease, and maintaining human contact with clinicians were the main suggestions for improving the effectiveness of the solution. CONCLUSIONS: Positive acceptance of m-RESIST services is related to its usefulness in meeting user needs, its capacity to empower them, and the possibility of maintaining human contact.

OBJECTIVE: We aimed to study the relationship between hyperprolactinemia (HPRL) and sexual dysfunction (SED) in a sample of patients being prescribed a dose-stable antipsychotic medication, and to evaluate sex differences in the prevalence of HPRL and SED and their relationship. METHOD: A cross-sectional study was carried out including patients between 18 and 55 years of age with a psychotic spectrum diagnosis who were attending community mental health services or hospitalized in medium and long stay units. Positive and Negative Syndrome scale, Calgary depression scale for schizophrenia, Personal and Social Performance scale, and Changes in Sexual Functioning questionnaire-short form were administered. Not later than 3 months, a determination of prolactin, follicle-stimulating hormone, luteinizing hormone, estrogen (only in women) and testosterone was performed. RESULTS: A final sample of 101 patients (30 women and 71 men) was recruited. Seventy-two patients (71.3%) showed HPRL. Sexual dysfunction was significantly higher in HPRL patients than in non-HPRL patients (79.17% vs 51.72%) (P = 0.006), and mean prolactin values were significantly higher in case of SED (P = 0.020). No sex differences were found in prevalence of HPRL or SED. Low Personal and Social Performance scale scores and HPRL were factors independently associated with SED, whereas alcohol use was an independent protector factor. CONCLUSIONS: In our study, SED was significantly related to HPRL without showing sex differences. Prevalence of HPRL and SED observed was higher than that in previous studies, which should be taken into consideration because these have been associated with higher morbimortality, and noncompliance and relapse, respectively.

BACKGROUND: Schizophrenia involves marked motivational and learning deficits that may reflect abnormalities in reward processing. The purpose of this study was to examine positive and negative feedback sensitivity in schizophrenia using computational modeling derived from the Wisconsin Card Sorting Test (WCST). We also aimed to explore feedback sensitivity in a sample with bipolar disorder. METHODS: Eighty-three individuals with schizophrenia and 27 with bipolar disorder were included. Demographic, clinical and cognitive outcomes, together with the WCST, were considered in both samples. Computational modeling was performed using the R syntax to calculate 3 parameters based on trial-by-trial execution on the WCST: reward sensitivity (R), punishment sensitivity (P), and choice consistency (D). The associations between outcome variables and the parameters were investigated. RESULTS: Positive and negative sensitivity showed deficits, but P parameter was clearly diminished in schizophrenia. Cognitive variables, age, and symptoms were associated with R, P, and D parameters in schizophrenia. The sample with bipolar disorder would show cognitive deficits and feedback abnormalities to a lesser extent than individuals with schizophrenia. CONCLUSION: Negative feedback sensitivity demonstrated greater deficit in both samples. Idiosyncratic cognitive requirements in the WCST might introduce confusion when supposing model-free reinforcement learning. Negative symptoms of schizophrenia were related to lower feedback sensitivity and less goal-directed patterns of choice.

BACKGROUND: Substance use in psychosis is an important field of study given that it can be a risk factor for the development of psychosis and can give rise to psychotic symptoms. Studies of substance use in first episode psychosis patients do not frequently assess non-pathological substance consumption among patients, but rather the prevalence of substance abuse or dependence disorders. Moreover, most of these studies do not address the effects of sex in sufficient depth, and the consumption of caffeine or tobacco, which are two of the most frequently used substances, is often not assessed. OBJECTIVES: The aim of this study was to compare patterns and quantities of substance use between first episode psychosis patients and healthy controls and between men and women, and explore the potential interactive effects between group (patients or controls) and sex. METHODS: A total of 158 participants (82 first episode psychosis patients and 76 healthy controls) were included in the study. Both adults and adolescents were included in the study. Frequency and amount of use of caffeine, tobacco, alcohol, cannabis, cocaine, hallucinogens, stimulants, and opiates were gathered. RESULTS: A significant main effect of sex was found for the frequency of use of tobacco (p=.050). Main effects of group were found for the quantity of tobacco (p<.001) and cannabis (p<.001) consumed, as well as main effects of sex for the quantity of alcohol (p=.003) and cannabis (p=.017) consumed. There were also interaction effects between group and sex for the frequency of use of tobacco (p=.005) and cannabis (p=.009), and for the amount of cannabis consumed (p=.049). Qualitative differences between males and females regarding combined substance use are also reported. CONCLUSIONS: Among patients, men used tobacco more frequently than women, but this sex difference was not the same for the control group, in which women smoked more often than men. Regarding cannabis, men smoked cannabis more frequently and in larger amounts than women, but only in the patients group, whereas no sex differences for cannabis were found for the controls. Main effects of group and sex for tobacco and alcohol, as well as the lack of differences for the frequency and amount of use of caffeine, are also commented. This is the first study to assess the different effects of sex on substance use in first episode psychosis patients and healthy controls.

Our aim was to examine predictive variables associated with the improvement in cognitive, clinical, and functional outcomes after outpatient participation in REPYFLEC strategy-based Cognitive Remediation (CR) group training. In addition, we investigated which factors might be associated with some long-lasting effects at 6 months' follow-up. Predictors of improvement after CR were studied in a sample of 29 outpatients with schizophrenia. Partial correlations were computed between targeted variables and outcomes of response to explore significant associations. Subsequently, we built linear regression models for each outcome variable and predictors of improvement. The improvement in negative symptoms at posttreatment was linked to faster performance in the Trail Making Test B. Disorganization and cognitive symptoms were related to changes in executive function at follow-up. Lower levels of positive symptoms were related to durable improvements in life skills. Levels of symptoms and cognition were associated with improvements following CR, but the pattern of resulting associations was nonspecific.

We report on a 61-year-old postmenopausal female with schizophrenia included in a raloxifene vs. placebo clinical trial and monitored during a 12-month period including a 3-month withdrawal period (6-9 months) without treatment. The patient was treated with raloxifene 60 mg/day adjuvant to antipsychotic medication for 6 months, medication was then withdrawn for 3 months and was reintroduced due to a worsening of symptoms. We assessed the patient with PANSS and other neuropsychological tests. The patient improved in psychopathology and cognitive level in some aspects related to executive functions. During 3 months without the drug, the patient's condition deteriorated. When the drug was reintroduced, improvements were again observed. Raloxifene may be useful as an adjuvant treatment for psychopathological symptoms and some cognitive aspects in women with chronic schizophrenia.

Aim: To assess whether exposure to childhood traumatic experiences is linked to the inflammatory markers neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) in people with a first-episode psychosis.Methods: A cross-sectional study was performed in 83 patients (21 females and 62 males) with a diagnosis of a first psychotic episode. All participants completed the self-reported Spanish version of the Childhood Trauma Questionnaire (CTQ). NLR, MLR, and PLR were calculated in each patient.Results: Highest CTQ scores were noted on the emotional neglect and abuse domains (mean ± SD = 10.92 ± 4.41; mean ± SD = 10.93 ± 4.78, respectively), being lowest for the sexual abuse domain (mean ± SD = 6.12 ± 2.41). Backward stepwise linear regressions showed that high emotional neglect significantly predicted increased PLR (ß = 0.452, P = .036), older age and high emotional neglect predicted increased NLR (ß = 0.483, P = .036; ß = 0.442, P = .06, respectively), and high emotional neglect, low physical neglect, high total Positive and Negative Syndrome Scale (PANSS) score, and cannabis and alcohol use predicted increased MLR (ß = 0.698, P = .003; ß = 0.672, P = .033; ß = 0.296, P = .027; ß = 0.390, P = .069; ß = 0.560, P = .078, respectively).Conclusions: Our results highlight the relationship between the exposure to emotional neglect and the inflammatory biomarkers NLR, MLR, and PLR in patients with a first-episode psychosis. This study has benefitted from controlling for confounders such as body mass index, smoking status, symptom severity, and alcohol and cannabis use.
