Sexually transmitted infections, sexual life and risk behaviours of people living with schizophrenia: systematic review and meta-analysis.

BACKGROUND: Sexually transmitted infections (STIs), along with sexual health and behaviour, have received little attention in schizophrenia patients. AIMS: To systematically review and meta-analytically characterise the prevalence of STIs and sexual risk behaviours among schizophrenia patients. METHOD: Web of Science, PubMed, BIOSIS, KCI-Korean Journal Database, MEDLINE, Russian Science Citation Index, SciELO and Cochrane Central Register were systematically searched from inception to 6 July 2023. Studies reporting on the prevalence or odds ratio of any STI or any outcome related to sexual risk behaviours among schizophrenia samples were included. PRISMA/MOOSE-compliant (CRD42023443602) random-effects meta-analyses were used for the selected outcomes. Q-statistics, I2 index, sensitivity analyses and meta-regressions were used. Study quality and publication bias were assessed. RESULTS: Forty-eight studies (N = 2 459 456) reporting on STI prevalence (including 15 allowing for calculation of an odds ratio) and 33 studies (N = 4255) reporting on sexual risk behaviours were included. Schizophrenia samples showed a high prevalence of STIs and higher risks of HIV (odds ratio = 2.11; 95% CI 1.23-3.63), hepatitis C virus (HCV, odds ratio = 4.54; 95% CI 2.15-961) and hepatitis B virus (HBV; odds ratio = 2.42; 95% CI 1.95-3.01) infections than healthy controls. HIV prevalence was higher in Africa compared with other continents and in in-patient (rather than out-patient) settings. Finally, 37.7% (95% CI 31.5-44.4%) of patients were sexually active; 35.0% (95% CI 6.6-59.3%) reported consistent condom use, and 55.3% (95% CI 25.0-82.4%) maintained unprotected sexual relationships. CONCLUSIONS: Schizophrenia patients have high prevalence of STIs, with several-fold increased risks of HIV, HBV and HCV infection compared with the general population. Sexual health must be considered as an integral component of care.

Cognitive reserve moderates the relationship between childhood maltreatment, objective and subjective cognition, and psychosocial functioning in individuals with first-episode psychosis.

OBJECTIVE: This study aimed to assess the relationship between childhood maltreatment (CM), objective and subjective cognition, and psychosocial functioning in adults with first-episode psychosis (FEP) by examining the moderating role of cognitive reserve (CR). A secondary objective was to explore whether unique CM subtypes (physical and/or emotional abuse, sexual abuse, physical and/or emotional neglect) were driving this relationship. METHOD: Sixty-six individuals with FEP (Mage = 27.3, SD = 7.2 years, 47% male) completed a comprehensive neuropsychological test battery, the Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA), the Functioning Assessment Short Test (FAST), the Childhood Trauma Questionnaire (CTQ), and the Cognitive Reserve Assessment Scale in Health (CRASH). Linear regression analyses were conducted to evaluate the interaction effect of CR between CM and cognitive and psychosocial variables, controlling for age, sex, and social desirability (CTQ-denial-minimization). RESULTS: In adults with FEP overall CM interacted with CR to predict COBRA-subjective cognitive complaints, but not neurocognitive or psychosocial functioning. Sexual abuse and physical neglect interacted with CR to predict verbal memory. Most of the CM subtypes interacted with CR to predict FAST-leisure time, whereas only emotional neglect interacted with CR to predict FAST-interpersonal relationships. Overall, greater CR was related to better functioning. CONCLUSIONS: The current results indicate that associations between specific CM subtypes, subjective and objective cognition, and psychosocial domains are moderated through CR with greater functioning. Early interventions focused on CR seeking to improve cognitive and psychosocial outcomes, with emphasis on improving subjective cognitive functions would be beneficial for individuals with FEP and CM.

Healthcare resource use and costs reduction with aripiprazole once-monthly in schizophrenia: AMBITION, a real-world study.

Objective: This study aims to compare the hospitalization rate in individuals with schizophrenia who started their treatment with aripiprazole once monthly (AOM400) or atypical oral antipsychotics (OA) in Spain. Methods: This is an observational and retrospective study based on the electronic medical records from the BIG-PAC database. The study population consisted of individuals diagnosed with schizophrenia who initiated their treatment with AOM400 (AOM cohort) or atypical OA (OA cohort) from 01/01/2017 to 31/12/2019. A 1:1 propensity score matching (PSM) procedure was conducted to match individuals of both cohorts. The number and duration of hospitalizations, persistence to treatment, healthcare resources use, and costs were analyzed after 12 months. Results: After the PSM, 1,017 individuals were included in each cohort [age: 41.4 years (SD: 10.6); males: 54.6%]. During the follow-up period, the AOM cohort had a 40% lower risk of hospitalization than the OA group [HR: 0.60 (95% confidence interval, CI: 0.49-0.74)]. The median time to the first hospitalization was longer in individuals with AOM400 compared to those with OA (197 days compared to 174 days; p < 0.004), whereas hospital admissions were shorter (AOM400: 6 compared to OA: 11 days; p < 0.001). After 12 months, individuals receiving AOM400 were more persistent than those with OA (64.9% compared to 53.7%; p < 0.001). The OA cohort required more healthcare resources, mainly visits to primary care physicians, specialists, and emergency rooms than those receiving AOM400 (p ≤ 0.005 in all comparisons). AOM400 reduced the costs of hospitalizations, and emergency room, specialist and primary care visits by 50.4, 36.7, 16.1, and 10.9%, respectively, in comparison to the treatment with atypical OA. AOM400 led to annual cost savings of €1,717.9 per individual, from the societal perspective. Conclusion: Aripiprazole once monthly reduces the number and duration of hospitalizations, together with the treatment costs of schizophrenia, as it reduces the use of healthcare resources and productivity losses in these individuals.

High blood levels of brain-derived neurotrophic factor (BDNF) mRNA in early psychosis are associated with inflammatory markers.

The brain-derived neurotrophic factor (BDNF) single nucleotide polymorphism (SNP) rs6265C > T, Val66Met, affects BDNF secretion and has been related to inflammatory processes. Both the rs6265 and BDNF protein levels have been widely investigated in neuropsychiatric disorders with conflicting results. In the present study we examined BDNF mRNA expression in blood considering the SNP rs6265 and its relationship with inflammatory markers in the early stages of psychosis. The rs6265 genotype and blood BDNF mRNA levels were measured in 34 at-risk mental states (ARMS) individuals, 37 patients with first-episode psychosis (FEP) and 42 healthy controls (HCs) by quantitative PCR and reverse transcription (RT)-qPCR using validated TaqMan assays. We also obtained measures of interleukin-6 (IL6) mRNA levels, fibrinogen, neutrophil-to-lymphocyte ratio (NLR) and high-sensitivity C-reactive protein. We identified that BDNF mRNA levels were associated with the rs6265 genotype in an allele-dose-dependent manner, with low expression levels associated with the T allele (Met substitution). Thus, we controlled for the rs6265 genotype in all analyses. Blood BDNF mRNA levels differed between diagnostic groups: patients with FEP exhibited higher blood BDNF mRNA levels than ARMS individuals, and the lowest levels were observed in HC. In addition, we observed significant correlations between BDNF mRNA levels and inflammatory markers (IL6 mRNA levels and NLR), controlled by the rs6265 genotype, in ARMS and FEP groups. This exploratory study suggests that the rs6265 genotype is associated with differential blood mRNA expression of BDNF that increases with illness progression and correlated with inflammation in the early stages of psychosis.

Cognitive biases in first-episode psychosis with and without attention-deficit/hyperactivity disorder.

Introduction: Psychotic disorders such schizophrenia and attention-deficit/hyperactivity disorder (ADHD) are neurodevelopmental disorders with social cognitive deficits. Specifically, biased interpretation of social information can result in interpersonal difficulties. Cognitive biases are prevalent in psychosis, but no previous study has investigated whether the type and severity of cognitive biases differ between subjects experiencing first-episode psychosis (FEP) with (FEP-ADHD+) and without ADHD (FEP-ADHD-). Methods: A total of 121 FEP outpatients at the Early Intervention Service of Reus were screened for childhood ADHD through the Diagnostic Interview for ADHD (DIVA). Cognitive biases were assessed by the Cognitive Biases Questionnaire for Psychosis (CBQp). CBQp scores of FEPs groups were compared with those of healthy controls (HCs) with an analysis of covariance. Spearman correlation analysis explored associations between CBQp scores and psychopathology. Results: Thirty-one FEPs met the criteria for childhood ADHD and reported significantly more cognitive bias [median (interquartile range): 47 (38-56)] than FEP-ADHD- [42 (37-48)] and HCs [38 (35.5-43)]. CBQp scores did not differ between FEP-ADHD-and HCs when adjusted for age and sex. After controlling for clinical differences, Intentionalising (F = 20.97; p < 0.001) and Emotional Reasoning biases (F = 4.17; p = 0.04) were more strongly associated with FEP-ADHD+ than FEP-ADHD-. Cognitive biases were significantly correlated with positive psychotic symptoms in both groups but only with depressive symptoms in FEP-ADHD- (r = 0.258; p = 0.03) and with poor functioning in FEP-ADHD+ (r = -0.504; p = 0.003). Conclusion: Cognitive bias severity increased from HCs to FEP-ADHD-patients to FEP-ADHD+ patients. FEP-ADHD+ patients may be a particularly vulnerable group in which metacognitive targeted interventions are needed.

Gradual Increase in Inflammation-Linked Glycoproteins and a Proatherogenic Lipoprotein Profile in the Early Stages of Psychosis as Characterized by 1H NMR Blood Analysis.

Minimally invasive prognostic markers of inflammation and dyslipidemia in individuals with a risk of psychosis, also called "at-risk mental state" (ARMS), or in the first episode of psychosis (FEP) are of utmost clinical importance to prevent cardiovascular disorders. We analyzed the plasma concentration of inflammation-linked glycoproteins (Glycs) and lipoprotein subclasses by proton nuclear magnetic resonance (1H NMR) in a single acquisition. Study participants were healthy controls (HCs, N = 67) and patients with ARMS (N = 58), FEP (N = 110), or early psychosis diagnosis with ≥2 episodes (critical period (CP), N = 53). Clinical biomarkers such as high-sensitivity C-reactive protein, interleukin 6, fibrinogen, insulin, and lipoproteins were also measured. Although all participants had normal lipoprotein profiles and no inflammation according to conventional biomarkers, a gradual increase in the Glyc 1H NMR levels was observed from HCs to CP patients; this increase was statistically significant for GlycA (CP vs HC). In parallel, a progressive and significant proatherogenic 1H NMR lipoprotein profile was also identified across stages of psychosis (ARMS and CP vs HC). These findings highlight the potential of using 1H NMR Glyc and lipoprotein profiling to identify blood changes in individuals with ARMS or FEP and pave the way for applications using this technology to monitor metabolic and cardiovascular risks in clinical psychiatry.

Maladaptive personality traits in patients with recent-onset psychosis: A case-control study using the Personality Inventory for the DSM-5 (PID-5).

BACKGROUND: The relationship between maladaptive personality traits and psychotic disorders in the early stages of disease has not been thoroughly investigated, even though it is essential for developing prevention and early intervention strategies. METHODS: The five domains and the 25 facets of the Personality Inventory for DSM-5 (PID-5) were compared between 102 patients with recent-onset psychosis (ROP) and 116 community subjects (C) with a general linear model including age and sex in the analyses. In addition, multiple linear regression models were used to identify which factors associated with the PID-5 domains in ROP, and correlation analyses were used to explore the relationship between personality traits. RESULTS: Patients with ROP, compared to C, exhibited higher scores in four out of the five domains with medium effect sizes (Cohen's f2 ≥ 0.15) in two of them: negative affect (NA, p = 0.013, f2 = 0.04), detachment (DET, p < 0.001, f2 = 0.15), disinhibition (DIS, p < 0.001, f2 = 0.14) and psychoticism (PSY, p < 0.001, f2 = 0.16). Significant group differences were observed in 15 of the 25 facets and the largest effects were observed in the facets of withdrawal (p ≤ 0.001, f2 = 0.20), irresponsibility (p < 0.001, f2 = 0.23) and unusual beliefs (p = 0.001, f2 = 0.22). Interestingly, being on antidepressants and high scores on the positive subscale of the Positive and Negative Syndrome Scale (PANSS) were associated with high scores of NA, antagonism (ANT) and PSY. CONCLUSIONS: Maladaptive personality traits were prominent in persons with ROP. These findings suggest that personality traits might play a role in vulnerability to psychosis and highlight the importance of evaluating personality in the early stages of psychosis.

Cross-sectional and longitudinal assessment of the association between DDR1 variants and processing speed in patients with early psychosis and healthy controls.

Recent evidence indicates that DDR1 participates in myelination and that variants of DDR1 are associated with decreased cognitive processing speed (PS) in schizophrenia (SZ). Here, we explored whether DDR1 variants were associated with PS in subjects diagnosed with an early psychosis (EP), a condition often preceding SZ. Data from two Spanish independent samples (from Reus and Santander) including patients with EP (n = 75 and n = 312, respectively) and healthy controls (HCs; n = 57 and n = 160) were analyzed. The Trail Making Test part A was used to evaluate PS. Participants underwent genotyping to identify DDR1 variants rs1264323 and rs2267641. Cross-sectional data were analyzed with general linear models and longitudinal data were analyzed using mixed models. We examined the combined rs1264323AA-rs2267641AC/CC genotypes (an SZ-risk combination) on PS. The SZ-risk combined genotypes were associated with increased PS in EP patients but not in HCs in the cross-sectional analysis. In the longitudinal analysis, the SZ-risk combined genotypes were significantly associated with increased PS in both HCs and EP patients throughout the 10-year follow-up but no genotype × time interaction was observed. These results provide further evidence that DDR1 is involved in cognition and should be replicated with other samples.

Emotional intelligence: a comparison between patients after first episode mania and those suffering from chronic bipolar disorder type I.

BACKGROUND: Deficits in emotional intelligence (EI) were detected in patients with bipolar disorder (BD), but little is known about whether these deficits are already present in patients after presenting a first episode mania (FEM). We sought (i) to compare EI in patients after a FEM, chronic BD and healthy controls (HC); (ii) to examine the effect exerted on EI by socio-demographic, clinical and neurocognitive variables in FEM patients. METHODS: The Emotional Intelligence Quotient (EIQ) was calculated with the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Performance on MSCEIT was compared among the three groups using generalized linear models. In patients after a FEM, the influence of socio-demographic, clinical and neurocognitive variables on the EIQ was examined using a linear regression model. RESULTS: In total, 184 subjects were included (FEM n = 48, euthymic chronic BD type I n = 75, HC n = 61). BD patients performed significantly worse than HC on the EIQ [mean difference (MD) = 10.09, standard error (s.e.) = 3.14, p = 0.004] and on the understanding emotions branch (MD = 7.46, s.e. = 2.53, p = 0.010). FEM patients did not differ from HC and BD on other measures of MSCEIT. In patients after a FEM, EIQ was positively associated with female sex (ß = -0.293, p = 0.034) and verbal memory performance (ß = 0.374, p = 0.008). FEM patients performed worse than HC but better than BD on few neurocognitive domains. CONCLUSIONS: Patients after a FEM showed preserved EI, while patients in later stages of BD presented lower EIQ, suggesting that impairments in EI might result from the burden of disease and neurocognitive decline, associated with the chronicity of the illness.

Incidence rate and distinctive characteristics of first episode psychosis during the COVID-19 pandemic: a multicenter observational study.

The COVID-19 pandemic has affected the mental health of people around the world. However, its impact on first-episode psychosis (FEP) remains unclear. The aim of this study was to determine the incidence rate (IR) and the clinical and sociodemographic characteristics of patients who developed FEP during the nine-month period following the COVID-19 outbreak in Spain and to compare these data to the corresponding period in the previous year. We included all patients (n = 220) treated for the first time during these two time periods at three FEP programs in Spain. The IR was 0.42/100,000 person-years during the pandemic vs. 0.54/100,000 in the prior year (p = 0.057). Compared to prior year, women accounted for a significantly higher proportion of FEP patients (46.3% vs. 28%; p = 0.005) during the COVID-19 period. This association was significant on the logistic regression analysis (odds ratio, female: 2.12 [confidence interval 1.17-3.82]; p = 0.014). These data reveal a non-significant trend towards a lower incidence of FEP during the pandemic period. Female sex was associated with a greater risk of developing FEP during the pandemic period, perhaps due to differences between males and females in the susceptibility and expression of psychosis. The findings of this study contribute to a better understanding of stress-related disorders.

Risk factors for metabolic syndrome in individuals with recent-onset psychosis at disease onset and after 1-year follow-up.

Metabolic syndrome (MetS) is a cluster of parameters encompassing the most dangerous heart attack risk factors, associated with increased morbidity and mortality. It is highly prevalent in recent-onset psychosis (ROP) patients. In this pilot study, we evaluated MetS parameters (fasting glucose, high-density lipoprotein (HDL) cholesterol (HDL-c), fasting triglycerides, waist circumference, and systolic and diastolic blood pressure), clinical symptoms, pharmacological treatment, lifestyle, and inflammatory markers in 69 patients with ROP and 61 healthy controls (HCs). At baseline, waist circumference (p = 0.005) and fasting triglycerides (p = 0.007) were higher in patients with ROP than in HCs. At the 1-year follow-up, patients showed clinical improvement, with a reduction in the positive and negative syndrome scale (PANSS) score (p < 0.001), dietary intake (p = 0.001), and antipsychotic medication dose (p < 0.001); however, fasting glucose (p = 0.011), HDL-c (p = 0.013) and waist circumference worsened (p < 0.001). We identified sex, age, BMI, dietary intake, physical activity, daily tobacco use, daily cannabis use, and antipsychotic doses as risk factors contributing to baseline MetS parameters. After 1-year follow-up, those factors plus the PANSS and Calgary Depression Scale for Schizophrenia (CDSS) scores were associated with MetS parameters. Further studies are needed to understand the contributions of the studied risk factors in patients with ROP at onset and during disease progression.

Shaped before birth: Obstetric complications identify a more severe clinical phenotype among patients presenting a first affective or non-affective episode of psychosis.

Obstetric complications (OCs) may contribute to the heterogeneity that characterizes psychiatric illness, particularly the phenotypic presentation of first episode psychoses (FEP). Our aim was to examine the relationship between OCs and socio-demographic, clinical, functioning and neuropsychological characteristics in affective and non-affective FEP. We performed a cross-sectional,study where we recruited participants with FEP between 2011 and 2021, and retrospectively assessed OCs using the Lewis-Murray scale. OCs were used as a dichotomous variable and further stratified into three subtypes: complications of pregnancy, abnormal fetal growth and development, and difficulties in delivery. We performed a logistic stepwise forward regression analysis to examine variables associated with the presence of OCs. Of the 104 participants (67 affective FEP and 37 non-affective FEP), 31.7% (n = 33) had experienced OCs. Subjects with OCs showed a more gradual emergence of prodromal symptoms as well as higher negative and total Positive and Negative Syndrome Scale (PANSS) scores. In the multivariate analysis, the presence of OCs was independently associated with a younger age at first episode of any type (OR = 0.904, p = 0.003) and slower emergence of prodromal symptoms (OR = 0.274, p = 0.011). When considering specific types of OCs, those related with fetal growth were associated with worse neuropsychological performance, while OCs at delivery were related to earlier onset of illness and more severe symptoms. In conclusion, OCs signaled a specific FEP phenotype characterized by earlier and more protracted onset of illness as well as more burdensome symptoms, independently of FEP type (i.e., affective vs non-affective). These results indicate a potential target of early intervention in FEP.

Prodromal phase: Differences in prodromal symptoms, risk factors and markers of vulnerability in first episode mania versus first episode psychosis with onset in late adolescence or adulthood.

OBJECTIVE: This study was aimed at identifying differences in the prodromal symptoms and their duration, risk factors and markers of vulnerability in patients presenting a first episode mania (FEM) or psychosis (FEP) with onset in late adolescence or adulthood in order to guide tailored treatment strategies. METHODS: Patients with a FEM or FEP underwent a clinical assessment. Prodromes were evaluated with the Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R). Chi-squared tests were conducted to assess specific prodromal symptoms, risk factors or markers of vulnerability between groups. Significant prodromal symptoms were entered in a stepwise forward logistic regression model. The probabilities of a gradual versus rapid onset pattern of the prodromes were computed with logistic regression models. RESULTS: The total sample included 108 patients (FEM = 72, FEP = 36). Social isolation was associated with the prodromal stage of a FEP whilst Increased energy or goal-directed activity with the prodrome to a FEM. Physically slowed down presented the most gradual onset whilst Increased energy presented the most rapid. The presence of obstetric complications and difficulties in writing and reading during childhood were risk factors for FEP. As for markers of vulnerability, impairment in premorbid adjustment was characteristic of FEP patients. No specific risk factor or marker of vulnerability was identified for FEM. CONCLUSION: Early characteristics differentiating FEP from FEM were identified. These findings might help shape early identification and preventive intervention programmes.

Perceived stress, social functioning and quality of life in first-episode psychosis: A 1-year follow-up study.

AIM: Quality of life (QoL) has been widely studied in people with schizophrenia. In the early phases of psychosis, it remains often impaired even after the remission of psychotic symptoms. The aim of this study was to explore QoL and social functioning during the first year after a first-episode psychosis (FEP), and to study potential moderating effects of stress measures. METHODS: Here, 61 FEP subjects and 55 healthy controls (HCs) were included. Sociodemographic data and clinical variables were collected through a semi-structured interview. Stress measures, social functioning and QoL were assessed with the Holmes-Rahe Social Readjustment Rating Scale, the Perceived Stress Scale, the Social Adaptation Self-Scale and the Euro-QoL-5D, respectively. Analysis of variance was employed with repeated measures and a mediation analysis at baseline and at 1-year follow-up was carried out. RESULTS: Patients reported lower QoL, poorer social functioning and more stress than HC. FEP patients significantly improved in QoL and stress measures over time, but not in social functioning. Perceived stress mediated the association between poorer social functioning and lower QoL. CONCLUSIONS: Social functioning at baseline may determine QoL over a 1-year follow-up period. Despite the improvement in most measures, patients do not achieve the level of well-being as the healthy group.

Relación entre el maltrato infantil y la adaptación social en una muestra de jóvenes atendidos en un servicio de intervención precoz en psicosis / Relationship between childhood trauma and social adaptation in a sample of young people attending an early intervention service for psychosis

INTRODUCCIÓN: El maltrato infantil se ha asociado a un mayor riesgo de psicosis, a una mayor severidad en síntomas psicopatológicos y a un peor pronóstico funcional en pacientes con un trastorno psicótico. El presente estudio pretende evaluar la relación entre el maltrato infantil, psicopatología y la adaptación social en una muestra de primeros episodios psicóticos (PEP) y de estados mentales de alto riesgo (EMAR). MATERIAL Y MÉTODOS: La muestra incluyó 114 jóvenes (18-35 años, 81 PEP y 33 EMAR) atendidos en un Servicio de Intervención Precoz en Psicosis. Se evaluaron síntomas positivos, negativos y depresivos con las escalas PANSS y Calgary de Depresión; los antecedentes de maltrato infantil con el Childhood Trauma Questionnaire; la adaptación social con la Escala Autoaplicada de Adaptación Social (SASS). Se utilizó el modelo de ecuaciones estructurales (SEM) para explorar relaciones entre psicopatología, maltrato infantil y dimensiones de la SASS en toda la muestra (incluyendo PEP y EMAR). Se repitió un análisis SEM exploratorio en la submuestra de PEP. RESULTADOS: Los EMAR presentaron más negligencia emocional y peor adaptación social, comparados con los PEP. El SEM muestra que el maltrato se asocia con una peor adaptación social en todos los dominios, de forma directa en dominios que implican relaciones interpersonales, y por una vía mediada por síntomas depresivos en los dominios que implican ocio y trabajo e intereses socioculturales. CONCLUSIONES: El maltrato infantil tiene un efecto negativo sobre la adaptación social en jóvenes en fases tempranas de las psicosis. Los síntomas depresivos son mediadores de una peor adaptación en aspectos funcionales relacionados con el ocio y el trabajo

INTRODUCTION: Childhood trauma has been associated with an increased risk of psychosis, a greater severity of psychopathological symptoms, and a worse functional prognosis in patients with psychotic disorders. The current study aims to explore the relationship between childhood trauma, psychopathology and social adaptation in a sample of young people with first episode psychosis (FEP) or at-risk mental states (ARMS). MATERIAL AND METHODS: The sample included 114 young people (18-35 years old, 81 FEP and 33 ARMS) who were attending an Early Intervention Service for Psychosis. Positive, negative and depressive symptoms were assessed with the PANSS and the Calgary Depression Scale; history of childhood trauma was assessed with the Childhood Trauma Questionnaire; social adaptation was assessed with the Social Adaptation Self-evaluation Scale (SASS). Structural equation modeling (SEM) was used to explore the relationship between childhood trauma, psychopathology and SASS dimensions in the global sample (including FEP and ARMS). An exploratory SEM analysis was repeated in the subsample of FEP patients. RESULTS: ARMS individuals reported more emotional neglect and worse social adaptation compared to FEP. SEM analysis showed that childhood trauma is associated with a worse social adaptation, in a direct way with domains involving interpersonal relationships, and mediated by depressive symptoms with those domains involving leisure, work and socio-cultural interests. CONCLUSIONS: Childhood trauma has a negative effect on social adaptation in young people with early psychosis. Depressive symptoms play a mediation role in this association, especially in domains of leisure and work

Glycated Haemoglobin Is Associated With Poorer Cognitive Performance in Patients With Recent-Onset Psychosis.

BACKGROUND: Glucose abnormalities and cognitive alterations are present before the onset of schizophrenia. We aimed to study whether glucose metabolism parameters are associated with cognitive functioning in recent-onset psychosis (ROP) patients while adjusting for hypothalamic-pituitary adrenal (HPA) axis measures. METHODS: Sixty ROP outpatients and 50 healthy subjects (HS) were studied. Cognitive function was assessed with the MATRICS Consensus Cognitive Battery. Glycated haemoglobin (HbA1c), glucose, insulin, and C-peptide levels were determined in plasma. The HOMA-insulin resistance index was calculated. Salivary samples were obtained at home on another day to assess the cortisol awakening response and cortisol levels during the day. Univariate analyses were conducted to explore the association between glucose metabolism parameters and cognitive tasks. For those parameters that were more clearly associated with the cognitive outcome, multiple linear regression analyses were conducted to adjust for covariates. Each cognitive task was considered the dependent variable. Covariates were age, sex, education level, diagnosis, antipsychotic and benzodiazepine treatment, body mass index (BMI), smoking, and HPA axis measures. Potential interactions between diagnosis and glucose parameters were tested. RESULTS: There were no significant differences in HPA axis measures or glucose parameters, with the exception of C-peptide (that was higher in ROP patients), between groups. ROP patients had a lower performance than HS in all cognitive tasks (p < 0.01 for all tasks). Of all glucose metabolism parameters, HbA1c levels were more clearly associated with cognitive impairment in cognitive tasks dealing with executive functions and visual memory in both ROP patients and HS. Multivariate analyses found a significant negative association between HbA1c and cognitive functioning in five cognitive tasks dealing with executive functions, visual memory and attention/vigilance (a ROP diagnosis by HbA1c negative interaction was found in this latter cognitive domain, suggesting that HBA1c levels are associated with impaired attention only in ROP patients). CONCLUSIONS: Our study found that HbA1c was negatively associated with cognitive functioning in both ROP patients and HS in tasks dealing with executive functions and visual memory. In ROP patients, HbA1c was also associated with impaired attention. These results were independent of BMI and measures of HPA axis activity.

Clinical and cognitive correlates of childhood attention-deficit/hyperactivity disorder in first-episode psychosis: A controlled study.

The relationship between childhood attention-deficit/hyperactivity disorder (c-ADHD) and psychosis has been understudied. Cognitive dysfunction is a core feature of both disorders, but no previous study has investigated whether first-episode psychosis (FEP) with c-ADHD (FEP-ADHD+) presents a different cognitive profile than FEP without c-ADHD (FEP-ADHD-). One hundred and thirty-three FEP outpatients were screened for c-ADHD through a diagnostic interview and underwent a comprehensive clinical and cognitive assessment with the MATRICS Consensus Cognitive Battery (MCCB). Cognitive differences among FEP groups, and a group of 65 healthy controls (HCs) were analysed by multivariate analysis of covariance. Nearly 25% of FEP fulfilled criteria for c-ADHD. Both FEP groups performed worse than HCs in speed processing, executive function and social cognition, but only the FEP-ADHD+group was significantly more impaired than the HC group in attention (F = 4.35; p = 0.04). Only the Trail Making Test A (TMT-A) (F = 6.99; p = 0.01) within the domain of processing speed and the Neuropsychological Assessment Battery (NAB) (F = 6.46; p = 0.01) within the domain of executive function reliably differentiated the two clinical groups. The FEP groups did not differ in the severity of psychopathology, but the FEP-ADHD+reported fewer years of education than the FEP-ADHD- and were more likely to use tobacco and cannabis and to require higher doses of antipsychotics to achieve a clinical response. In conclusion, we found a gradient of severity in cognitive performance between groups, with FEP-ADHD+ having the greatest cognitive impairment. Our results suggest that FEP-ADHD+ represents a subgroup with a worse prognosis than FEP-ADHD-.

Diferencias en la presentación clínica de primeros episodios psicóticos entre población de origen marroquí y población autóctona / Comparison between a morocco and a native-born population, in a sample of first episode psychosis

INTRODUCCIÓN: Las diferencias étnicas han sido estudiadas tanto en esquizofrenia como en los primeros episodios psicóticos (PEP).??En estudios realizados en los Países Bajos se ha descrito que en los varones de origen marroquí es más frecuente un episodio psicótico y presentar mayor severidad en la sintomatología. Sin embargo, no existen estudios en España en PEP en población marroquí comparada con autóctona. OBJETIVOS: Explorar las diferencias clínicas entre la población inmigrante de origen marroquí y la población autóctona, en una muestra de PEP recogida en una unidad de hospitalización de agudos. MATERIAL Y MÉTODOS: Se evaluó la sintomatología y el funcionamiento al ingreso y al alta, así como el consumo de cannabis y la dosis de tratamiento antipsicótico y el perfil de efectos adversos en una muestra de 83 pacientes con PEP. Se compararon los pacientes de origen marroquí con los de la población autóctona mediante análisis univariantes y la independencia de las asociaciones fue evaluada mediante análisis de regresión logística. RESULTADOS: El 28,9% de la muestra era de origen marroquí. No se encontraron diferencias en cuanto a la sintomatología al ingreso y al alta. Comparados con los autóctonos, los de origen marroquí eran mayoritariamente hombres, tenían menos años de educación, presentaban peor funcionamiento, menor uso de cannabis, mejor perfil de efectos secundarios y una tendencia al mayor uso de LAI. Tras el análisis multivariante, solo un peor funcionamiento (OR 0,93; IC 95%: 0,88-0,99; p = 0,02) y menos años de educación (OR 0,75; IC 95%: 0,56-1,01; p = 0,05) permanecieron significativamente asociados a ser de origen marroquí. CONCLUSIONES: Existen diferencias sociodemográficas y clínicas entre personas con PEP de origen marroquí y población autóctona. Nuestros resultados señalan que debería contemplarse la trascendencia de la competencia cultural en la evaluación y tratamiento de los PEP

INTRODUCTION: Ethnic differences have been studied previously in schizophrenia and first episodes of psychosis (FEP). Previous studies in Netherlands have reported a higher incidence of psychosis in male Moroccan immigrants and more clinical severity. However there is lack of studies in Spain with morocco population and FEP. OBJECTIVES: This study aims to determine the clinical differences in a sample of FEP between Morocco and Spanish population, recruited in a hospitalisation unit. MATERIAL AND METHODS: Descriptive and cross-sectional study of 83 inpatients (FEP). Functionality and symptomatology were evaluated at entry and discharge, the pattern of use of cannabis was evaluated at entry, the dose of antipsychotic and the pattern of side-effects at discharge. Comparisons between native-born population and Morocco population was made with univariate analysis and logistic regression was made for evaluating the independence of the associations. RESULTS: The 28.9% of the sample was Morocco group. No significance differences were found in clinical characteristics between groups at entry or at discharge. Compared with native-born, the Morocco group were more male, with less years of education, worse functionality, reported less use of cannabis, a better pattern of side effects and a tendency of more prescription of LAis. After the multivariate analysis, just remains a lower functionality (OR 0.93; IC 95%: 0.88-0.99, P=0.02) and lower years of education (OR 0.75; IC 95%: 0.56-1.01, P=0.05), remain significative with being related with Morocco origin. CONCLUSIONS: Our study provides evidence for ethnic differences in Morocco population with FEP. Patients with Morocco ethnicity have more probability of being males, less years of educations. Have lower functionality and a better profile of side effects

The impact of sex and cannabis on clinical features in first-admitted patients with psychosis.

There is a scarcity of studies investigating the effect of sex on the clinical and treatment characteristics of first-admitted patients with first-episode psychosis (FEP). The reasons for using cannabis and the effect of cannabis on clinical features have not received enough attention either. We aim therefore, to investigate sex differences in the reasons for cannabis use and to determine the effects of sex, cannabis use and their interaction on clinical variables at admission and at discharge from the inpatient unit. 204 first-admitted FEPs in two inpatient units in Spain were included. The reasons for using cannabis were determined using the Dixon questionnaire. Clinical variables were compared between sexes and between cannabis users and non-users. Cannabis use was more frequent in males, but females were more likely to smoke cannabis to "feel relaxed". There was a main effect of sex on positive psychotic symptoms and antipsychotics dose and an interaction effect of cannabis and sex on global functioning at discharge .Our findings show sex differences in the reasons for cannabis use and in some clinical and treatment characteristics among FEP patients. More studies focusing on gender perspectives are needed to develop more individualized treatments.
