Somatic multicomorbidity and disability in patients with psychiatric disorders in comparison to the general population: a quasi-epidemiological investigation in 54,826 subjects from 40 countries (COMET-G study).

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.

Optimizing subjective wellbeing with amisulpride in first episode schizophrenia or related disorders.

BACKGROUND: Subjective response (SR) to antipsychotic medication is relevant for quality of life, adherence and recovery. Here, we evaluate (1) the extent of variation in SR in patients using a single antipsychotic; (2) the association between subjective and symptomatic response; and (3) predictors of SR. METHODS: Open-label, single treatment condition with amisulpride in 339 patients with a first episode of a schizophrenia spectrum disorder, at most minimally treated before inclusion. Patients were evaluated at baseline, before start with amisulpride and after four weeks of treatment with the Subjective Wellbeing under Neuroleptic scale, the Positive and Negative Syndrome Scale, and the Calgary Depression Scale for Schizophrenia. RESULTS: (1) 26.8% of the patients had a substantial favorable SR, and 12.4% of the patients experienced a substantial dysphoric SR during treatment with amisulpride. (2) Modest positive associations were found between SR and 4 weeks change on symptom subscales (r = 0.268-0.390, p values < 0.001). (3) Baseline affective symptoms contributed to the prediction of subjective remission, demographic characteristics did not. Lower start dosage of amisulpride was associated with a more favorable SR (r = -0.215, p < 0.001). CONCLUSIONS: We conclude that variation in individual proneness for an unfavorable SR is substantial and only modestly associated with symptomatic response. We need earlier identification of those most at risk for unfavorable SR and research into interventions to improve SR to antipsychotic medication in those at risk.

Results of the COVID-19 mental health international for the health professionals (COMET-HP) study: depression, suicidal tendencies and conspiracism.

INTRODUCTION: The current study aimed to investigate the rates of anxiety, clinical depression, and suicidality and their changes in health professionals during the COVID-19 outbreak. MATERIALS AND METHODS: The data came from the larger COMET-G study. The study sample includes 12,792 health professionals from 40 countries (62.40% women aged 39.76 ± 11.70; 36.81% men aged 35.91 ± 11.00 and 0.78% non-binary gender aged 35.15 ± 13.03). Distress and clinical depression were identified with the use of a previously developed cut-off and algorithm, respectively. STATISTICAL ANALYSIS: Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses, and Factorial Analysis of Variance (ANOVA) tested relations among variables. RESULTS: Clinical depression was detected in 13.16% with male doctors and 'non-binary genders' having the lowest rates (7.89 and 5.88% respectively) and 'non-binary gender' nurses and administrative staff had the highest (37.50%); distress was present in 15.19%. A significant percentage reported a deterioration in mental state, family dynamics, and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (24.64% vs. 9.62%; p < 0.0001). Suicidal tendencies were at least doubled in terms of RASS scores. Approximately one-third of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop clinical depression was associated with a history of Bipolar disorder (RR = 4.23). CONCLUSIONS: The current study reported findings in health care professionals similar in magnitude and quality to those reported earlier in the general population although rates of clinical depression, suicidal tendencies, and adherence to conspiracy theories were much lower. However, the general model of factors interplay seems to be the same and this could be of practical utility since many of these factors are modifiable.

Psychological impact of the COVID-19 pandemic and lockdown in a Spanish sample with anxiety disorder: sex differences.

The early psychological impact of the COVID-19 pandemic and lockdown is greater in people with mental disorders. This study explored the differences in the psychological impact on people with an anxiety disorder by sex in Spain.

Early Impact of the COVID-19 Outbreak on Sleep in a Large Spanish Sample.

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.

The Multi-Component Smoking Cessation Support Programme (McSCSP) is effective in patients with severe mental disorder without gender differences. / El programa multicomponente de apoyo para el cese del tabaquismo (McSCSP) es efectivo en pacientes con trastorno mental grave sin diferencias de género.

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.

Are older adults also at higher psychological risk from COVID-19?

OBJECTIVE: Given the lack of information on the psychological impact of COVID-19 on people aged ≥60, we aimed to describe their psychological responses to this pandemic and lockdown situation and compare them with those under 60 years of age. METHODS: Secondary analysis of a larger online cross-sectional study designed to determine the psychological impact of the COVID-19 pandemic and lockdown across Spain. We analyzed a total of 1690 respondents aged ≥60 years and compared them with 13,363 respondents under 60 years of age. We employed the Depression, Anxiety, and Stress Scale and the Impact of Event Scale to evaluate psychological responses. RESULTS: In all, 52.6% of women and 34.3% of men were found to be probable cases of any emotional distress (p < 0.001). In both sexes, the most common psychological response was avoidance behavior (34.7% and 23.8%, respectively), followed by depression (28.5 and 14.2%). Older women and men were considered probable cases of any emotional distress less often than younger ones (women: 52.6% vs. 72.3%, p < 0.001; men: 34.3% vs. 50.6%, p < 0.001). Finally, the results of the binary logistic regression showed that only depressive and stress responses are psychological factors associated with age group [age ≥ 60 years, O.R. = 0.617 (95% CI = 0.501 - 0.759) and 0.437 (95% CI = 0.334 - 0.573), respectively]. CONCLUSION: Contrary to our hypothesis and despite the high percentage of emotional distress we found in older adults, especially women, they are actually at lower risk of developing depressive and stress consequences from COVID-19 and lockdown than those under 60 years of age. That said, we believe our results highlight the need for expert guidance in this age group, especially older women living alone.

Impact of the coronavirus outbreak on mental health in the different Spanish regions.

COVID-19 is an infectious disease that has affected millions of people worldwide, Spain being one of the countries most affected by the pandemic. It is key to study its impact on the mental health of the Spanish population during the lockdown situation.

Alcohol use and risk factors for self-harm behavior in Spanish adolescents. / Consumo de alcohol y factores de riesgo de conductas autolesivas en adolescentes españoles.

Self-harm behaviors in children and adolescents constitute an important public health problem with prevalence figures in the clinical population between 40 and 80%. The objectives of the study were to analyze and compare the Spanish sub-samples of two studies, SEYLE and WE-STAY to determine prevalence, self-harm patterns and factors associated with self-harm behaviors, notably the use of alcohol or drugs. The questionnaires used in both studies were the Global School Health Survey (GSHS), the Beck Depression Inventory (BDI-II), the Strengths and Difficulties Questionnaire (SDQ). The self-harm behaviors were evaluated with a modified 6-item version of s the Deliberate Self-Harm Inventory (DSHI). The independence of the study's categorical variables was assessed using the Chi-square test. The change in the relative risk of self-harm between the SEYLE study and WE-STAY was evaluated through the odds ratio (OR) calculation. Two different logistic regression models were calculated in order to establish the factors associated with self-harm behaviors in each study. In the present study, the rates of DSH vary according to study and sex, ranging from 0.58% to 2.08%, and different patterns of self-harm are evidenced by sex, with males self-injuring more frequently by self-inflicted blows and burns, while young women more often cut themselves. The presence of depressive symptoms and alcohol use were the factors most strongly associated with an increased risk of DSH.

Las conductas autolesivas en niños y adolescentes constituyen un importante problema de salud pública con cifras de prevalencia en la población clínica entre el 40 y 80%. Los objetivos del estudio son analizar y comparar las submuestras españolas de dos trabajos, SEYLE y WE-STAY, para conocer la prevalencia, los patrones de autolesión y los factores asociados a las conductas autolesivas, en particular el consumo de alcohol o drogas. Los cuestionarios utilizados en ambos estudios fueron la Encuesta Global de Salud Escolar (GSHS), el Inventario de Depresión de Beck (BDI-II), el Cuestionario de Fortalezas y Dificultades (SDQ). Los comportamientos autolesivos fueron evaluados con una versión modificada de 6 ítems basada en el Inventario de Autolesiones Deliberadas (DSHI). La independencia de las variables categóricas del estudio se evaluó mediante la prueba Ji-Cuadrado. El cambio en el riesgo relativo de autolesión entre el estudio SEYLE y WE-STAY, se evaluó a través del cálculo de odds ratio (OR). Se calcularon dos modelos de regresión logística diferentes con el fin de establecer los factores asociados con comportamientos autolesivos en cada estudio. En el presente estudio las tasas de DSH varían en función del estudio y del sexo en un rango entre 0,58% y 2,08%, presentando patrones de autolesiones diferentes según el sexo, los hombres se autolesionaron más frecuentemente mediante golpes autoinfligidos y quemaduras, mientras que las mujeres se hicieron más frecuentemente cortes. La presencia de síntomas depresivos y el consumo de alcohol fueron los factores asociados de forma más robusta a un mayor riesgo de DSH.

Early Psychological Correlates Associated With COVID-19 in A Spanish Older Adult Sample.

OBJECTIVE: Main aims of the study are to examine the early psychological correlates associated with the COVID-19 pandemic and lockdown on the mental health of a Spanish older adult sample and to analyze the influence of past mental disorder (PMD) and current mental disorder (CMD) on those correlates. METHODS: Cross-sectional study based on an online snowball recruiting questionnaire. Psychological correlates assessed with the Depression, Anxiety, and Stress Scale (DASS-21) and Impact of Event Scale (IES). Binary and multinomial logistic regression models were used to identify risk and protective factors. RESULTS: Final sample included 2,194 individuals aged 60 years or more (mean age [SD]: 65.62 [5.05]; females: 1,198 [54.6%]). There were 342 (15.6%) individuals who reported a PMD and 162 (7.4%) who reported a CMD. Avoidant (32.1%) and depressive (25.6%) styles were the most prevalent, regardless of mental health status. Main risk factors for negative affectivity were female gender and history CMD or PMD. However, job stability and the ability to enjoy free time were generally associated with better outcomes. No differences were found in psychological correlates between those with no lifetime history of mental disorder versus PMD on the DASS-21 or IES. However, CMD was associated with higher anxiety scores on the DASS-21 (odds ratio: 1.838, p < .001). CONCLUSION: Regardless of mental status, avoidant and depressive styles were the most prevalent in this older adult sample. Main protective factor in all subgroups was the ability to enjoy free time, whereas the main risk factors were being female and current or past history of mental disorder.

History of Lifetime Cannabis Use Is Associated with Better Cognition and Worse Real-World Functioning in Schizophrenia Spectrum Disorders.

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.

"Readiness to Change" Predicts Efficacy of Reduction among Smokers with Severe Mental Illness.

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).

Predictive factors of alcohol consumption in adolescents: data from 1-year follow-up prospective study. / Factores predictores del consumo de alcohol en adolescentes: datos de un estudio prospectivo de 1 año de seguimiento.

Alcohol use/abuse is a health problem in adolescents. The last Survey on use of drugs in Secondary Schoolers carried out in Spain (ESTUDES 2014-2015), reveals that 76.8% of adolescents aged 14 to 18 years consumed alcohol in the previous year and 68.2% in the last month. The aim of this study is to determine the medium-term factors associated with alcohol consumption in a sample of Spanish adolescents. The present study was carried out as a part of the Saving and Empowering Young Lives project in Europe (SEYLE) project. The final sample was composed of 708 students, assessed at two times [basal (T0) and one year later (T1)] [males: 51.98%, basal mean age (SD)=4.43 (0.67)]. Univariate and multivariate regression analyses were performed in order to investigate relationships between possible predictive variables found at time T0 and alcohol consumption at time T1. At basal time (T0) the prevalence of alcohol abuse was 25.56%, whereas the prevalence one year later was 49.72% (T1). Variables that significantly predict alcohol abuse within a year are: previous alcohol abuse at T0 (p<0.001), previous abuse of drugs (p=0.011), parents attending their sporting events (p=0.005), peer problems (p=0.019), and lack of prosocial behaviour (p=0.043). In the light of our results, it can be concluded that, in adolescents, externalizing disorders seem to be determining factors of medium-term alcohol consumption.

El uso/abuso de alcohol es un problema de salud en los adolescentes. La última Encuesta sobre uso de drogas en Enseñanzas Secundarias realizada en España (ESTUDES 2014-2015), pone de manifiesto que 76,8% de los adolescentes entre 14 y 18 años consumieron alcohol en el último año y 68,2% en el último mes. El principal objetivo es determinar los factores que se asocian con el consumo de alcohol a medio plazo en una muestra de adolescentes españoles. El estudio forma parte del proyecto Saving and Empowering Young Lives in Europe (SEYLE). La muestra final estuvo compuesta por 708 estudiantes, evaluados en dos momentos temporales [basal (T0) y al año (T1)] [varones: 51,98%, edad media basal (DE)=4,43 (0,67)]. Se realizaron análisis de regresión univariante y multivariante, con el fin de investigar las relaciones entre posibles variables predictoras descritas en el momento temporal T0 y el consumo de alcohol en el momento T1.En el momento basal (T0) la prevalencia de abuso de alcohol fue del 25,56%, mientras que la prevalencia al año fue del 49,72% (T1). Las variables que predicen de forma significativa el abuso de alcohol al cabo de un año son: abuso previo del alcohol en el momento T0 (p< 0,001), abuso previo de drogas (p=0,011), padres que asisten a sus competiciones deportivas (p=0,005), problemas de relación con compañeros (p=0,019) y ausencia de comportamiento prosocial (p=0,043). A la vista de nuestros resultados se puede concluir que, en adolescentes, los trastornos externalizantes parecen ser factores determinantes de consumo de alcohol a medio plazo.

Factors associated with tobacco consumption in patients with depression. / Factores asociados con consumo de tabaco en pacientes con depresión.

Smoking and depression are related in a bidirectional way: smoking is the primary avoidable cause of illness and death in patients with depression, and depression is one of the most consistent risk factors for smoking. The main objective of this study is to investigate the relationship between smoking and depression, analyzing sociodemographic and clinical variables such as severity of symptoms, subtype of affective disorder, and its impact on suicidal behavior in the clinical population.A sample of 201 patients, over 18 years of age [mean age (SD) = 53.76 (10.36) years; women = 132 (65.7%)], with a history of depressive episode (unipolar or bipolar) or dysthymia (ICD 10 criteria) was studied.Current smoking prevalence was 43.2% and life-time prevalence 61.2%. No statistically significant differences in smoking prevalence between men and women were found (X2 = 3.896, p = 0.143). The average age of onset was 17.81 (5.60) years. There was a tendency towards a linear association between number of cigarettes/day consumed and severity of depression according to the Hamilton Depression Scale (HDRS) in current smokers (Pearson's R = 0.298, p = 0.050). Multinomial logistic regression analysis showed that current tobacco consumption was associated with higher HDRS scores, with each additional point on the HDRS increasing the likelihood of smoking by 0.062 [p = 0.032; OR (95% CI) = 1.064 (1.005-1.125)].Our results showed that depressed patients present higher prevalence of current smoking than the general population, also suggesting a relationship between severity of consumption and severity of depressive symptoms.

Tabaquismo y depresión se relacionan de forma bidireccional: el tabaquismo es la primera causa evitable de enfermedad y muerte en pacientes con depresión, y la depresión constituye uno de los factores de riesgo de tabaquismo más consistentes. El principal objetivo del presente trabajo es profundizar en la relación entre tabaquismo y depresión, analizando variables socio-demográficas y clínicas como la gravedad de los síntomas, el subtipo de trastorno afectivo, y su impacto en las conductas suicidas en población clínica.Se estudió una muestra de 201 pacientes, mayores de 18 años [edad media (SD) = 53,76 (10,36) años; mujeres = 132 (65,7%)], con historia de episodio depresivo (unipolar o bipolar) o distimia (criterios CIE 10).La prevalencia de tabaquismo actual fue 43,2% y la prevalencia vida 61,2%, no existiendo diferencias estadísticamente significativas entre hombres y mujeres (X2 = 3,896; p = 0,143). La edad media de inicio fue 17,81 (5,60) años. Se observó tendencia a asociación lineal entre número de cigarrillos/día consumidos y gravedad de la depresión según la Escala de Hamilton para la Depresión (HDRS) en los consumidores actuales de tabaco (R de Pearson = 0,298; p = 0,050). El análisis de regresión logística multinomial puso de manifiesto que el consumo actual de tabaco se asocia con puntuaciones más elevadas en la HDRS, de modo que cada incremento de un punto en dicha escala, la posibilidad de fumar aumenta en 0,062 [p = 0,032; OR (95% CI) = 1,064 (1,005-1,125)].Nuestros resultados muestran que los pacientes deprimidos presentan mayor prevalencia de consumo actual de tabaco que la población general, sugiriendo además una relación entre gravedad de consumo y gravedad de los síntomas de depresión.

Obstetric Phenotypes in the Heterogeneity of Schizophrenia.

Schizophrenia is a complex mental disorder with genetic and environmental components. Obstetric complications (OCs) are one of the most common environmental risk factors described. However, despite being different in timing and outcome, OCs are usually described as a homogeneous entity. In the present study, we evaluate the presence of different patterns of OCs evaluated with the Lewis-Murray Scale in chronic schizophrenia patients (n = 101) and their association with a crude marker of the intrauterine environment such as weight at birth.OCs related with abnormal fetal growth (p < 0.001) and OCs during gestation (p = 0.003) were associated with lower birth weight. However, difficulties in delivery, complications in pregnancy, and OCs all together (as a set) were not associated with weight at birth.Our results infer that OCs cannot be taken as a homogeneous group. Different patterns of OCs result in different birth weights, which is associated with specific metabolic, cognitive, and brain structure outcomes.

Substance use or abuse, internet use, psychopathology and suicidal ideation in adolescents. / Uso y abuso de sustancias psicotrópicas e internet, psicopatología e ideación suicida en adolescentes.

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.

Tobacco and cognitive performance in schizophrenia patients: the design of the COGNICO study. / Tabaco y rendimiento cognitivo en pacientes con esquizofrenia: diseño del estudio COGNICO.

People with schizophrenia constitute a substantial part of the people who still smoke. Regarding cognitive performance, the self-medication hypothesis states that patients smoke to improve their cognitive deficits based on the stimulating effects of nicotine. The aim of this paper is to describe in detail the methodology used in the COGNICO study. A quasi-experimental, observational, prospective, multicenter study with follow-ups over 18 months was conducted in three cities in northern Spain (Oviedo, Ourense and Santiago de Compostela). A total of 81 outpatient smokers with schizophrenia were recruited with a mean age 43.35 years (SD = 8.83), 72.8% of them male. They were assigned to 3 groups: a) control group (smokers); b) patients who quit smoking using nicotine patches; c) patients who quit smoking with Varenicline. The MATRICS neuropsychological battery was applied as a primary measure. In addition, a comprehensive assessment of patients was performed, including the number of cigarettes per day, physical and psychological dependence on nicotine and CO expired. Clinical evaluation (PANSS, HDRS, CGI, C-SSRS), anthropometric measurements and vital signs assessment was also performed. The aim is to identify the relationship between the pattern of tobacco use and cognitive performance by comparing scores on the neuropsychological battery MATRICS during the follow-up periods (3, 6, 12 and 18months). The importance of this study lies in addressing a topical issue often ignored by clinicians: the unacceptably high rates of tobacco use in patients with severe mental disorders.

Las personas con esquizofrenia constituyen una parte sustancial de las personas que todavía fuman. La hipótesis de la automedicación en relación al rendimiento cognitivo mantiene que los pacientes fuman para mejorar su déficit cognitivo basándose en los efectos estimulantes de la nicotina. El objetivo de este artículo es describir la metodología del estudio COGNICO. Estudio cuasiexperimental, observacional, prospectivo, multicéntrico y  con seguimiento a 3, 6, 12 y 18 meses. Fue llevado a cabo en tres ciudades del norte de España (Oviedo, Ourense y Santiago de Compostela). Se reclutaron 81pacientes con esquizofrenia fumadores (edad media de 43,35 años (DT=8,83). 72,8% varones). Se asignaron a 3 grupos: a) control: pacientes fumadores; b) pacientes que dejan de fumar mediante parches de nicotina; c) pacientes que dejan de fumar mediante vareniclina. Como medida primaria se aplicó la batería neuropsicológica MATRICS. Además, se llevó a cabo una evaluación comprehensiva de los pacientes, que incluía  el número de cigarrillos por día, la dependencia física y psicológica a la nicotina y el CO expirado. También se realizó una evaluación clínica general (PANSS, HDRS, ICG, C-SSRS) así como un seguimiento de las medidas antropométricas y los signos vitales. Se pretende  identificar la relación entre el patrón de consumo de tabaco y el rendimiento cognitivo mediante la comparación de las puntuaciones en la batería neuropsicológica MATRICS durante los períodos de seguimiento.

Psychometric evaluation of the negative syndrome of schizophrenia.

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.
