RESUMEN
BACKGROUND: The prevalence of medical illnesses is high among patients with psychiatric disorders. The current study aimed to investigate multi-comorbidity in patients with psychiatric disorders in comparison to the general population. Secondary aims were to investigate factors associated with metabolic syndrome and treatment appropriateness of mental disorders. METHODS: The sample included 54,826 subjects (64.73% females; 34.15% males; 1.11% nonbinary gender) from 40 countries (COMET-G study). The analysis was based on the registration of previous history that could serve as a fair approximation for the lifetime prevalence of various medical conditions. RESULTS: About 24.5% reported a history of somatic and 26.14% of mental disorders. Mental disorders were by far the most prevalent group of medical conditions. Comorbidity of any somatic with any mental disorder was reported by 8.21%. One-third to almost two-thirds of somatic patients were also suffering from a mental disorder depending on the severity and multicomorbidity. Bipolar and psychotic patients and to a lesser extent depressives, manifested an earlier (15-20 years) manifestation of somatic multicomorbidity, severe disability, and probably earlier death. The overwhelming majority of patients with mental disorders were not receiving treatment or were being treated in a way that was not recommended. Antipsychotics and antidepressants were not related to the development of metabolic syndrome. CONCLUSIONS: The finding that one-third to almost two-thirds of somatic patients also suffered from a mental disorder strongly suggests that psychiatry is the field with the most trans-specialty and interdisciplinary value and application points to the importance of teaching psychiatry and mental health in medical schools and also to the need for more technocratically oriented training of psychiatric residents.

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.

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

BACKGROUND: There is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation. METHODS: We analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls. RESULTS: The impact of PRS-SZ on psychosis showed significant dependence on co-presence of affective dysregulation in NEMESIS-2 [relative excess risk due to interaction (RERI): 1.01, p = 0.037] and in EUGEI (RERI = 3.39, p = 0.048). This was particularly evident for delusional ideation (NEMESIS-2: RERI = 1.74, p = 0.003; EUGEI: RERI = 4.16, p = 0.019) and not for hallucinatory experiences (NEMESIS-2: RERI = 0.65, p = 0.284; EUGEI: -0.37, p = 0.547). A similar and stronger pattern of results was evident for CA (RERI delusions and hallucinations: NEMESIS-2: 3.02, p < 0.001; EUGEI: 6.44, p < 0.001; RERI delusional ideation: NEMESIS-2: 3.79, p < 0.001; EUGEI: 5.43, p = 0.001; RERI hallucinatory experiences: NEMESIS-2: 2.46, p < 0.001; EUGEI: 0.54, p = 0.465). CONCLUSIONS: The results, and internal replication, suggest that the effects of known genetic and non-genetic risk factors for psychosis are mediated in part through an affective pathway, from which early states of delusional meaning may arise.

Important questions remain about the profile of cognitive impairment in psychotic disorders across adulthood and illness stages. The age-associated profile of familial impairments also remains unclear, as well as the effect of factors, such as symptoms, functioning, and medication. Using cross-sectional data from the EU-GEI and GROUP studies, comprising 8455 participants aged 18 to 65, we examined cognitive functioning across adulthood in patients with psychotic disorders (n = 2883), and their unaffected siblings (n = 2271), compared to controls (n = 3301). An abbreviated WAIS-III measured verbal knowledge, working memory, visuospatial processing, processing speed, and IQ. Patients showed medium to large deficits across all functions (ES range = -0.45 to -0.73, p < 0.001), while siblings showed small deficits on IQ, verbal knowledge, and working memory (ES = -0.14 to -0.33, p < 0.001). Magnitude of impairment was not associated with participant age, such that the size of impairment in older and younger patients did not significantly differ. However, first-episode patients performed worse than prodromal patients (ES range = -0.88 to -0.60, p < 0.001). Adjusting for cannabis use, symptom severity, and global functioning attenuated impairments in siblings, while deficits in patients remained statistically significant, albeit reduced by half (ES range = -0.13 to -0.38, p < 0.01). Antipsychotic medication also accounted for around half of the impairment in patients (ES range = -0.21 to -0.43, p < 0.01). Deficits in verbal knowledge, and working memory may specifically index familial, i.e., shared genetic and/or shared environmental, liability for psychotic disorders. Nevertheless, potentially modifiable illness-related factors account for a significant portion of the cognitive impairment in psychotic disorders.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) forced Spain to implement unprecedented lockdown restriction. In this context, different factors could worsen sleep quality, but the impact of the pandemic and lockdown on sleep is still mostly unknown. In this cross-sectional study, we describe self-reported sleep disturbances in people without mental health disorders from a large Spanish sample (n = 15,070). METHODS: During the early phase of the lockdown (19-26 March), an online survey was launched using a snowball sampling method and included sociodemographic and clinical data along with the Depression, Anxiety, and Stress Scale (DASS-21) and the Impact of Event Scale (IES). Two items of the IES were employed to assess sleep characteristics. Descriptive and bivariate analysis and logistic regression models were performed. RESULTS: Difficulty initiating or maintaining sleep were reported by 23.9% of the sample and was associated in the regression model with age (OR = 1.008, p = .003), female sex (OR = 1.344, p < .001), an income reduction >50% (OR = 1.248, p = .037), having one (OR = 1.208, p = .029) and two or more (OR = 1.299, p = .035) elderly dependents, drinking alcohol (OR = 1.129, p = .024), and a higher score on DASS-21 depression (OR = 1.148, p < .001), anxiety (OR = 1.218, p < .001), or stress (OR = 1.302, p < .001) subscales, whereas being able to enjoy free time (OR = 0.604, p < .001) and painting or listening to music (OR = 0.853, p = .012) were protective factors. Dreams related to COVID-19 were reported by 12.9% of the sample and were associated in the regression model with female sex (OR = 1.617, p < .001), being married (OR = 1.190, p = .015), self-employed (OR = 1.373, p = .032), or a civil servant (OR = 1.412, p = .010), having been tested for COVID-19 (OR = 1.583, p = .012), having infected family or friends (OR = 1.233, p = .001), reading news about coronavirus (OR = 1.139, p = .023), drinking alcohol (OR = 1.251, p < .001), and higher scores on DASS-21 depression (OR = 1.102, p < .001), anxiety (OR = 1.222, p < .001), or stress (OR = 1.213, p < .001) subscales, while protective factors were older age (OR = 0.983, p < .001) and being retired (OR = 0.625, p = .045). CONCLUSIONS: These findings could help clinicians and public health systems design and deliver tailored interventions, such as internet-delivered campaigns, to promote sleep quality in the general population.

Until now, no follow-up studies had simultaneously evaluated executive functions, other non-executive functions related cognitive functions, and impulsivity in a large enough sample of moderate to severe alcohol use disorder (AUD) patients. The main objective of the present study was to compare neuropsychological performance and its relation to alcohol use in patients with AUD and healthy controls, and to determine the evolution of cognitive impairment and alcohol use over time. For this purpose, a 6-month follow-up study was designed to compare a sample of 100 outpatients with AUD (DSM-5 criteria) with 100 matched healthy controls. The patient group was recruited from three different health centres in Spain located in Orense, Gijón and Barcelona. The assessment consisted of a systematic battery of cognitive tests to evaluate the following functions: attention, anterograde memory, processing speed, verbal fluency, executive function, and implicit attitude toward alcoholic beverages. We also compared clinical variables associated with alcohol use, such as alcohol craving and impulsivity. After 6 months, anterograde memory, working memory, and resistance to interference improved remarkably in AUD patients, although not enough to match the normal population. With regard to clinical variables, there was a small but significant cognitive improvement related to a reduction in alcohol use and impulsivity. Executive dysfunction and other non-executive functions related cognitive functions impairment can be considered prognostic factors in outpatients with moderate to severe AUD.
Hasta la fecha, ningún estudio de seguimiento había evaluado simultáneamente la función ejecutiva, otras funciones no ejecutivas relacionadas con funciones cognitivas y la impulsividad en una muestra suficientemente grande de pacientes con trastorno por uso de alcohol (TUA) entre moderado y grave. Este estudio tuvo como objetivo principal comparar el desempeño neuropsicológico y su relación con el uso de alcohol en pacientes con TUA y en controles sanos, y determinar la evolución del deterioro cognitivo y el uso de alcohol a largo plazo. Con este fin, se diseñó un estudio de seguimiento de seis meses para comparar una muestra de 100 pacientes ambulatorios con TUA (criterios del DSM-5) emparejados con 100 controles sanos. Los pacientes se reclutaron de tres centros sanitarios diferentes de España, Orense, Gijón y Barcelona. La evaluación consistió en una batería sistematizada de pruebas cognitivas para evaluar las siguientes funciones: atención, memoria anterógrada, velocidad de procesamiento, fluidez verbal, función ejecutiva y actitud implícita hacia bebidas alcohólicas. También se compararon variables clínicas asociadas al consumo de alcohol, como el craving y la impulsividad. Después de seis meses, la memoria anterógrada, memoria de trabajo y resistencia a la interferencia mejoraron notablemente en los pacientes con TUA, aunque no llegaron a igualar la población general. Respecto de las variables clínicas, hubo una pequeña pero significativa mejoría cognitiva relacionada con una reducción del consumo de alcohol y de la impulsividad. La disfunción ejecutiva y otras funciones no ejecutivas relacionadas con el deterioro cognitivo pueden considerarse factores pronósticos en pacientes ambulatorios con TUA entre moderado y grave.

High prevalence of smoking in people with severe mental disorders (SMD) contributes to their medical morbidity and reduced life expectancy. Despite the evidence of gender differences in smoking cessation, few studies have tested those differences among people with SMD. This is a non-randomized, open-label, prospective, 9-month follow-up multicentre trial to examine gender differences in the efficacy, safety and tolerability of a Multi-Component Smoking Cessation Support Programme (McSCSP). The results showed that there were no significant differences in short- (males 44.9% vs females 57.7%, chi-square = 1.112, p = 0.292) or long-term efficacy (week 24: males 40.8%, females 42.3%, chi-square = 0.016, p = 0.901; week 36: males 36.7%, females 38.5%, chi-square = 0.022, p = 0.883) between gender, neither controlled by diagnosis or treatment. Regarding safety and tolerability, there was significant increase in abdominal perimeter in males [from 105.98 (SD 13.28) to 108.52 (SD 14.01), t = -3.436, p = 0.002)], but not in females. However, there were no significant gender differences in adverse events (constipation, abnormal/vivid dreams, nausea/vomiting or skin rash/redness around patch site). In conclusion, we have demonstrated that is effective and safe to help either male or female patients with stabilized SMD to quit smoking. However, it might be a tendency in females to respond better to varenicline treatment in the short-term. Future research with larger samples is required to more clearly determine whether or not the there are differences, in addition to their reliability and robustness.
La elevada prevalencia del tabaquismo en personas con trastorno mental grave (TMG) contribuye a su morbilidad médica y reduce su esperanza de vida. A pesar de la existencia de diferencias de género en el cese del tabaquismo, pocos estudios han evaluado esas diferencias en personas con TMG. Este es un ensayo multicéntrico de seguimiento prospectivo, no aleatorizado, abierto de 9 meses para examinar las diferencias de género en la eficacia, seguridad y tolerabilidad de un programa multicomponente de apoyo para el cese del tabaquismo (McSCSP). Los resultados mostraron que no hubo diferencias de género significativas en la eficacia a corto (hombres 44,9% vs mujeres 57,7%, chi cuadrado = 1,112, p = ,292) ni a largo plazo (semana 24: hombres 40,8%, mujeres 42,0.3%, chi cuadrado = 0.016, p = ,901; semana 36: hombres 36,7%, mujeres 38,5%, chi cuadrado = 0,022, p = ,883), incluso controlando por diagnóstico o tratamiento. Con respecto a la seguridad y la tolerabilidad, hubo un aumento significativo en el perímetro abdominal en los hombres [de 105,98 (DT 13,28) a 108,52 (DT 14,01), t = -3,436, p = ,002)], pero no en las mujeres. Sin embargo, no hubo diferencias de género significativas en los eventos adversos (estreñimiento, sueños anormales/vívidos, náuseas/vómitos o erupción cutánea/enrojecimiento alrededor de la zona del parche). En conclusión, hemos demostrado que es efectivo y seguro ayudar a los hombres y mujeres con TMG estabilizados a dejar de fumar. Sin embargo, podría haber una tendencia en las mujeres a responder mejor al tratamiento con vareniclina a corto plazo. Se requiere investigación futura con muestras más amplias para determinar con más claridad la existencia de diferencias, además de la fiabilidad y robustez.

RATIONALE: Reducing the frequency of long-acting injectable antipsychotic medication may reduce carer burden. OBJECTIVES: To evaluate the impact of reduced frequency of long-acting injectable antipsychotic medication on carer burden in stable patients with schizophrenia. METHODS: Carer burden was assessed using the Involvement Evaluation Questionnaire (IEQ) within a 52-week, prospective, single-arm, non-randomised, open-label, international, multicentre study evaluating the impact of transitioning stable patients with schizophrenia to paliperidone palmitate 3-monthly (PP3M) from paliperidone palmitate 1-monthly (PP1M). RESULTS: 159 carers completed the IEQ (mean [standard deviation, SD] age: 54.8 [12.8] years); 52.2% were the patients' parent and > 50% had >32 h/week of patient contact. At baseline, mean [SD] IEQ total score was in the lower range (23.8 [12.6]), reflecting patient stabilisation. At last observation carried forward (LOCF) endpoint, the IEQ total score decreased by a mean (95% CI) of -4.0 (-5.9, -2.1), indicating a significant overall reduction in carer burden (P < 0.0001). The six IEQ items with the highest carer burden at baseline were within the urging and worrying domains, in which burden was significantly improved at LOCF endpoint (P < 0.0001). Exploratory analyses found that higher carer burden was associated with lower functional remission (Personal and Social Performance score >70) at baseline and LOCF endpoint, and with the patient being part of the carer's household. Shorter disease duration correlated with better general health of carers at LOCF endpoint. CONCLUSION: Reducing the frequency of antipsychotic medication administration in stable patients with schizophrenia by switching from PP1M to PP3M may reduce carer burden.

Brain damage related to alcohol consumption is associated with impairments in cognitive functions, among which memory and verbal learning stand out. The main objective is to evaluate memory and verbal learning in a sample of 111 patients with alcohol use disorder (AUD) versus 78 with major depressive disorder (MDD) and 100 healthy controls. The evaluation included sociodemographic and clinical variables, the Hamilton Depression Scale (HDRS) and the California Verbal Learning Test (CVLT). One-way ANOVA was used for comparisons between the 3 groups and two-way ANCOVAS including different covariates. The one-way ANOVA shows that patients with AUD and MDD had scores similar to each other and lower than those of the control group (p <0.001), with the exception of the Cued CVLT (worse scores in MDD vs AUD, p <0.001). After including age, sex and years of completed studies as covariates, the differences between the AUD and MDD groups persisted compared to the control group (p ≤ 0.003) in all indices except for the Immediate Free CVLT and the Cued CVLT (worse performance in MDD vs AUD, p = 0.022 and p = 0.035, respectively). In the second ANCOVA, after controlling for depression severity, differences were only detected between AUD patients and healthy controls (p ≤ 0.007). Patients with AUD present a significant impairment in learning and verbal memory when compared with patients with MDD and with healthy people.
El daño cerebral relacionado con el consumo de alcohol se asocia a alteraciones de las funciones cognitivas, entre las que destacan memoria y aprendizaje verbal. El objetivo principal es evaluar memoria y aprendizaje verbal en una muestra de 111 pacientes con trastorno por consumo de alcohol (TCA) versus 78 con trastorno de depresión mayor (TDM) y 100 controles sanos. La evaluación incluyó variables sociodemográficas y clínicas, la Escala de Hamilton para la Depresión (HDRS) y el Test de Aprendizaje Verbal de California (CVLT). Se utilizó ANOVA de un factor para comparaciones entre los 3 grupos y ANCOVAS bidireccionales incluyendo diferentes covariables. El ANOVA de un factor muestra que los pacientes con TCA y TDM obtienen puntuaciones similares entre sí e inferiores a las del grupo control (p < 0,001), con excepción del CVLT Guiado (peores puntuaciones en TDM vs TCA, p < 0,001). Tras incluir como covariables la edad, sexo y los años de estudios completados, persisten las diferencias entre los grupos de TCA y TDM frente al grupo control (p ≤ 0,003) en todos los índices con excepción del CVLT Libre Inmediato y del CVLT Guiado (peor rendimiento en TDM vs TCA, p = 0,022 y p = 0,035, respectivamente). En el segundo ANCOVA, tras controlar por gravedad de la depresión, únicamente se detectan diferencias entre los pacientes con TCA y los controles sanos (p ≤ 0,007). Los pacientes con TCA presentan una importante alteración en aprendizaje y memoria verbal al compararlos con pacientes con TDM y con personas sanas.
RESUMEN
The main objective of the present study is to analyze the presence of cognitive impairment associated with alcohol consumption in patients with moderate or severe alcohol use disorder seeking outpatient treatment for their dependence. To do this, we compared a sample of 111 patients with active alcohol use disorder who initiated ambulatory treatment with 100 healthy controls. We compared sociodemographic and clinical variables associated with alcohol consumption, such as alcohol craving and impulsivity. A systematized battery of cognitive tests was also used in the comparison, which allowed the evaluation of the following functions: Attention, anterograde memory, processing speed, verbal fluency, executive function and implicit attitude towards alcoholic beverages. Compared with healthy controls, patients with moderate or severe alcohol use disorder performed significantly worse in all tests used, and therefore in all cognitive functions evaluated, but for two tests, the Iowa Gambling Test and the Implicit Association Test. The analysis through a correlation matrix of the patient group indicates that patients who report more impulsivity and more chronic alcohol abuse and with more addiction are those who suffer greater deterioration in their cognitive function. Cognitive damage associated with alcohol consumption was distributed heterogeneously among patients. The present study confirms the presence of cognitive deterioration associated with alcohol consumption in patients seeking outpatient treatment.
El objetivo principal del presente estudio es analizar la presencia del deterioro cognitivo asociado al consumo de alcohol en los pacientes con trastorno por uso de alcohol moderado o grave que demandan tratamiento de deshabituación alcohólica ambulatorio. Para ello, se comparó una muestra de 111 pacientes con trastorno por uso de alcohol activo que iniciaban tratamiento ambulatorio versus 100 controles sanos. Se compararon variables sociodemográficas y clínicas asociadas al consumo de alcohol, como el craving de alcohol y la impulsividad. También se empleó en la comparación una batería sistematizada de pruebas cognitivas que permitía valorar las siguientes funciones: atención, memoria anterógrada, velocidad de procesamiento, fluidez verbal, función ejecutiva y actitud implícita ante las bebidas alcohólicas. En comparación con los controles sanos, los pacientes con trastorno por uso de alcohol moderado o grave presentaban un rendimiento significativamente inferior en todas las pruebas utilizadas, y por ello en todas las funciones cognitivas evaluadas, con la excepción de dos pruebas, el Iowa Gambling Test y el Implicit Association Test. El análisis a través de una matriz de correlaciones del grupo de pacientes indica que los pacientes que refieren más impulsividad y un consumo abusivo de alcohol más cronificado y con más adicción son los que presentan un mayor deterioro en su función cognitiva. El daño cognitivo asociado al consumo de alcohol se distribuyó de forma heterogénea entre los pacientes. El presente estudio confirma la presencia del deterioro cognitivo asociado al consumo de alcohol en los pacientes que demandan tratamiento ambulatorio.

BACKGROUND: First-degree relatives of patients with psychotic disorder have higher levels of polygenic risk (PRS) for schizophrenia and higher levels of intermediate phenotypes. METHODS: We conducted, using two different samples for discovery (n = 336 controls and 649 siblings of patients with psychotic disorder) and replication (n = 1208 controls and 1106 siblings), an analysis of association between PRS on the one hand and psychopathological and cognitive intermediate phenotypes of schizophrenia on the other in a sample at average genetic risk (healthy controls) and a sample at higher than average risk (healthy siblings of patients). Two subthreshold psychosis phenotypes, as well as a standardised measure of cognitive ability, based on a short version of the WAIS-III short form, were used. In addition, a measure of jumping to conclusion bias (replication sample only) was tested for association with PRS. RESULTS: In both discovery and replication sample, evidence for an association between PRS and subthreshold psychosis phenotypes was observed in the relatives of patients, whereas in the controls no association was observed. Jumping to conclusion bias was similarly only associated with PRS in the sibling group. Cognitive ability was weakly negatively and non-significantly associated with PRS in both the sibling and the control group. CONCLUSIONS: The degree of endophenotypic expression of schizophrenia polygenic risk depends on having a sibling with psychotic disorder, suggestive of underlying gene-environment interaction. Cognitive biases may better index genetic risk of disorder than traditional measures of neurocognition, which instead may reflect the population distribution of cognitive ability impacting the prognosis of psychotic disorder.

BACKGROUND: Data on associations between cannabis use and psychopathology, cognition and functional impairment in schizophrenia spectrum disorders (SSD) is controversial. OBJECTIVES: To examine the effect of cannabis on psychopathology, cognition and real-world functioning in SSD patients. METHOD: Naturalistic cross-sectional study, 123 clinically stable SSD outpatients. ASSESSMENT: demographic and clinical data, psychometric evaluation: Positive and Negative Syndrome, Hamilton Depression Rating, Clinical Global Impression (CGI), Personal and Social Performance and Screen for Cognitive Impairment in Psychiatry (SCIP) scales. Patients were classified as cannabis user patients (CUP) and non cannabis user patients (NCUP) according to self-report, both lifetime and last year. STATISTICAL ANALYSIS: chi-square, Student t test, ANOVA (Duncan post hoc), and general linear model analysis for adjusting for antipsychotic doses. RESULTS: Mean age 40.75, 66.7% male, single (66.7%), prior hospital admissions 2.75, mean length of illness 13.85 years. 53.7% were lifetime cannabis users and 8.9% last year users. Lifetime CUP had more hospitalizations (p = 0.013) at a younger age (p = 0.002), and showed better cognitive functioning globally (CGI-C: p = 0.045) and on working memory and processing speed (SCIP-2: p = 0.039; SCIP-5: p = 0.033) and worse functioning in socially useful activities (p = 0.014) than NCUP. All these differences remained after adjusting for antipsychotic doses. Last year cannabis users had worse mood (Hamilton Depression Rating Scale 9.66 vs. 5.64; p = 0.002), but this difference disappears when adjusting for antipsychotic doses. CONCLUSIONS: Lifetime cannabis use is associated with better working memory and processing speed and worse real-world functioning in the area of socially useful activities in patients with schizophrenia-related disorders. Clinicians should, therefore, be aware of it to provide patient-centred care in their daily clinical practice.

AIMS: Smoking cessation in subjects with a severe mental illness (SMI) is a challenging but attainable goal. Furthermore, the identification of variables involved in the quitting process is a highly relevant factor in clinical practice. This study aimed to analyze the influence of smokers' motivation in smoking reduction and cessation and select the most suitable way of measuring motivation. METHODS: This is a secondary analysis of a 9-month, multicenter trial examining a Multicomponent Smoking Cessation Program in 82 adult outpatients with SMI. At the end of the preparation stage, the smokers' motivational level was evaluated with the University of Rhode Island Change Assessment Scale. This allowed us to rate subjects using a continuous measure ("Readiness to Change," RTC) and group them in "Stages of Change" (SOC). Regression analyses were carried out to identify predictors of the efficacy outcomes: a reduction in at least 50% of the cigarettes smoked per day (CPD), a reduction in the expired carbon monoxide (CO), and complete abstinence from smoking. RESULTS: We studied differences in measurements of motivational levels independently (RTC and SOC) for patients who had a reduction in at least 50% of the CPD and for patients who achieved complete abstinence from smoking. However, these differences did not reach statistical significance during the follow-up study with a logistic mixed-effects model. In a linear mixed-effects model, the reduction of expired CO was significantly associated with RTC, at the end of the active treatment phase and during follow-up (ß: -1.51; SD 0.82; p < 0.01). CONCLUSION: The motivation level achieved in the preparation phase predicted the reduction of expired CO over a given period when calculated by a continuous measure (RTC).

BACKGROUND: Twenty-one percent of subjects with depressive disorder (DD) smoke. This prevalence is expected to be related to healthcare resources utilization (HRU) and sick leave, thereby accounting for substantial costs to the National Health System (NHS) and to society that still need to be characterized. The objective was to estimate cost of illness in patients with DD according to their smoking status. METHODS: We used the 2011/2012 National Health Survey to document HRU and lost-workday equivalents (LWDE). Men and women 18+ years old with a DD self-reported to a physician in the past 12 months were categorized into: smokers (daily smokers), former smokers, and never smokers. HRU and LWDE were computed on an annualized basis. Multivariate general linear models adjusted for sex, age, and comorbidities were applied. RESULTS: Data from 1,816 subjects (381 smokers, 290 former smokers, and 1,145 never smokers) were analyzed. Smokers had higher total per patient annual costs (thousands, 3.14), and higher annual healthcare costs (2.53) than former smokers (2.35, p < .1; and 1.93, p < .05) and never smokers (2.42, p < .05; and 2.06, p < .1): with excess costs of 0.79 and 0.72 for total annual costs and 0.60 and 0.47 for annual healthcare costs (p = .029 and p = .056, respectively). CONCLUSIONS: Smoking DD subjects were associated with higher HRU and costs from both the societal and healthcare perspectives, when compared with former and never smokers in the Spanish general population. Supporting people with DD to quit smoking might therefore be a value-for-money health policy in Spain.

Substance and Internet use or abuse, psychopathology and suicidal ideation appear to be related. The aim of this study is to investigate the association between use of psychotropic substances, inadequate Internet use, suicidal ideation and other psychopathological symptoms within the adolescent population. The present study was carried out as part of the Saving and Empowering Young Lives in Europe (SEYLE) project, funded by the European Union. The sample is composed of 1026 adolescents aged between 14 and 16 years from 12 state schools in Asturias (530 men and 496 women). This study adds to the possibility of knowing whether the SEYLE data is confirmed in a relatively isolated and recession hit province of Spain. In the present study the following consumption rates were obtained: a) alcohol 11.89% in males and 7.86% in females; b) tobacco: 4.15% and 5.44 % in males and females respectively; c) other drugs: 6.98% in males and 4.44% in females; d) maladaptive or pathological Internet use: 14.53% and 20.77% in males and females respectively. The variables that predict suicide ideation in the logistic regression model were: previous suicide attempts, depression, maladaptive or pathological Internet use, peer problems and alcohol consumption.
El uso o abuso de sustancias o internet, la psicopatología y la ideación suicida parecen estar relacionadas. El objetivo del presente estudio es investigar la asociación en población adolescente entre consumo de sustancias potencialmente adictivas, uso inadecuado de internet, psicopatología e ideación suicida. El estudio forma parte del proyecto europeo Saving and Empowering Young Lives in Europe (SEYLE). La muestra está compuesta por 1026 adolescentes con edades comprendidas entre 14 y 16 años procedentes de 12 centros escolares públicos del Principado de Asturias (530 varones y 496 mujeres). El presente trabajo aporta la posibilidad de conocer si los datos generales del proyecto SEYLE varían en una zona relativamente aislada y socioeconómicamente en recesión. Las tasas obtenidas de consumo de las distintas sustancias y de uso de internet fueron: a) alcohol: 11,89% en varones y 7,86% en mujeres; b) tabaco: 4,15% y 5,44% en varones y mujeres respectivamente; c) otras drogas: 6,98% en varones y un 4,44% en mujeres; d) uso de internet desadaptativo o patológico: 14,53% y 20,77% en varones y mujeres respectivamente. Se ha observado que las variables con capacidad predictiva sobre las conductas suicidas fueron: tentativas suicidas previas, síntomas depresivos, uso desadaptativo o patológico de internet, problemas con los compañeros y consumo de alcohol.

In this paper, we reviewed the available instruments for assessing the negative syndrome of schizophrenia, describing their strengths and weaknesses. Current instruments were classified into two categories according to their content validity and assessment approach as first- or second-generation instruments. The BPRS, SANS, the SENS and the PANSS belong to the first generation, while the BNSS, the CAINS and the MAP-SR belong to the second generation. The NSA can be considered a transitional instrument between the two. First-generation instruments have more content validity problems than second-generation instruments do, as they do not accurately reflect the currently accepted negative syndrome (they do not include all negative symptoms and signs or they include symptoms from other dimensions). They also have more problems relative to the use of behavioural referents instead of internal experiences of deficits when assessing symptoms, which may lead to measuring functioning instead of negative symptoms. Further research needs to be done in this area in order to ensure the evaluation of primary negative symptoms and internal experiences involved in negative symptoms rather than external behaviours.

The aim of this review was to update and summarize the scientific knowledge on the long term outcomes of the different pharmacological treatment options for opioid dependence currently available and to provide a critical discussion on the different treatment options based on these results. We performed a literature search using the PubMed databases and the reference lists of the identified articles. Data from research show that the three pharmacological options reviewed are effective treatments for opioid dependence with positive long term outcomes. However, each one has its specific target population and setting. While methadone and buprenorphine are first line options, heroin-assisted treatment is a second line option for those patients refractory to treatment with methadone with concomitant severe physical, mental, social and/or functional problems. Buprenorphine seems to be the best option for use in primary care offices. The field of opioid dependence treatment is poised to undergo a process of reinforcement and transformation. Further efforts from researchers, clinicians and authorities should be made to turn new pharmacological options into clinical reality and to overcome the structural and functional obstacles that maintenance programmes face in combatting opioid dependence.
