Assessment of short forms of recurrent atrial extra systoles by echocardiography with left atrial strain in ambulatory patients without organic cardiopathy / Evaluación de formas cortas de extrasístoles auriculares recurrentes mediante ecocardiografía con deformación auricular izquierda en pacientes ambulatorios sin cardiopatía orgánica

Abstract Aim: To analyse the potential usefulness and clinical relevance of the assessment by echocardiography with left atrial strain, based on the myocardial atrial deformation curves with speckle-tracking velocity vector imaging (VVI), in the analysis of short-form recurrent atrial extra systoles in ambulatory patients not suffering from organic cardiopathy. Methods: We designed a descriptive, prospective, and observational study including 270 patients between the ages of 18 and 75 assessed during an outpatient cardiology consultation attended due to palpitations over a period of two years. Using ambulatory electrocardiographic monitoring, we selected cases with short forms of repetitive atrial extrasystole, isolated or recurrentatrial fibrillation and a control group formed by those patients without repetitive ectopia. All patients underwent a thorough echocardiographic study during their first cardiological visit. Results: The analysis of the dynamic curves segmental deformation generated after an atrial extrasystole can reveal different points of origin of the extrasystole and detect specific anatomical alterations in the interatrial conduction at the level of the Bachmann's fascicle showing different models of electro anatomical activation possibly involved in the appearance of repetitive forms. Higher values of dyssynchrony between the septal and lateral wall and elongation in the time of interatrial electromechanical conduction could also be related to the existence of repetitive ectopic beats. Conclusions: Our ambulatory study employing the left atrial longitudinal strain, particularly in its segmental analysis, provides new insights into its the usefulness and potential clinical relevance.

Resumen Objetivo: Analizar la utilidad y relevancia clínica de la evaluación mediante ecocardiografía basada en las curvas de deformación auricular miocárdica con imágenes vectoriales de velocidad (VVI) de speckle-tracking, en el análisis de las extrasístoles auriculares recurrentes de corta duración en pacientes ambulatorios sin cardiopatía orgánica. Métodos: Se diseñó un estudio descriptivo, prospectivo y observacional que incluyó a 270 pacientes de entre 18 y 75 años evaluados durante una consulta externa de cardiología a la que acudieron por palpitaciones durante un periodo de dos años.

Effects of raloxifene on cognition in postmenopausal women with schizophrenia: a 24-week double-blind, randomized, parallel, placebo-controlled trial.

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

Ingresos hospitalarios de desintoxicación en mujeres con alcoholismo y otras toxicomanías / Hospitalized inpatient detoxification of women with alcoholism and other drug addictions

Objetivos: Analizar las características descriptivas de los ingresos de Desintoxicación por Alcoholismo u otras Toxicomanías en mujeres que requieren un ingreso hospitalario de desintoxicación en nuestro medio. Diseño: Retrospectivo, incluyendo todas las mujeres ingresadas en la Unidad de Desintoxicación de la Corporació Sanitària i Universitària Parc Taulí de Sabadell (Barcelona) entre enero de 2010 y junio 2013. Utilizamos criterios diagnósticos DSM-IV-TR y una estadística descriptiva. De forma secundaria, se compararon mujeres que habían requerido un ingreso por alcohol como sustancia principal de desintoxicación (APD) y aquellas con alcohol como sustancia única de desintoxicación (AUD) en relación al resto de la muestra. Resultados: Desde Enero de 2010 a Junio de 2013 se realizaron 360 ingresos en la Unidad de Desintoxicación, de los cuales 82 fueron mujeres (22,7%). Se trataba de mujeres de edad media (43,3 años) que ingresaron principalmente para la desintoxicación de más de una sustancia. El tóxico principal fue el alcohol con 67,1% (n=55), seguido de las politoxicomanías que incluyeron casos con abuso de varias sustancias como motivo principal de desintoxicación. A nivel de otra comorbilidad psiquiátrica, la mayoría de las mujeres no presentaban ningún diagnostico DSM-IV-TR (53,7%, n=44). Las mujeres AUD (n=33) fueron significativamente mayores de edad, utilizaron más benzodiacepinas y tuvieron menos diagnósticos en el Eje II. Conclusiones: El principal motivo de desintoxicación en mujeres de nuestro medio es el alcohol. Existen diferencias significativas entre las mujeres con desintoxicación de alcohol y aquellas con consumos comórbidos de otras sustancias

Objectives: To analyze the characteristics of inpatient detoxification hospitalizations for alcoholism and other drug addictions in women from our area. Design: We use a retrospective design. The subjects were inpatient women hospitalized in the Detoxification Unit at the Corporació Sanitària i Universitària Parc Taulí de Sabadell (Barcelona) between January 2010 and June 2013. Diagnoses were made by DSM-IV-TR criteria. The statistics were descriptive. In a secondary analysis, we compared women with alcohol as a principal reason of admission (APD) with women with alcohol as an isolated reason of admission (AUD) in relation with the rest of the sample. Results: From January 2010 to June 2013 there were 360 admissions in the Detoxification Unit, 82 of whom were women (22.7%). These were middle-aged women (43.3 years), who were mainly admitted for detoxification from more than one substance. The main drug involved in the abuse was alcohol (67.1%, n=55), followed by multiple drug abuse as a main reason for detoxification. Considering psychiatric comorbidity, most of the women did not display any DSM-IV-TR diagnosis criteria (53.7%,= 44). Women in AUD (n=33) were significantly older, used more benzodiazepines and had fewer Axis II diagnoses. Conclusions: The main reason for inpatient detoxification in women in our area is alcohol. There are significant differences between women with alcohol detoxifications and women with comorbid abuse of other substances

Risk of re-attempts and suicide death after a suicide attempt: A survival analysis.

BACKGROUND: Suicide is the primary cause of unnatural death in Spain, and suicide re-attempts a major economic burden worldwide. The risk factors for re-attempt and suicide after an index suicide attempt are different. This study aims to investigate risk factors for re-attempt and suicide after an index suicide attempt. METHODS: This observational study is part of a one-year telephone management program. We included all first-time suicide attempters evaluated in the emergency department at Parc Taulí-University Hospital (n = 1241) recruited over a five-year period (January 2008 to December 2012). Suicide attempters were evaluated at baseline using standardized instruments. Bivariate logistic regression models were used to identify risk factors. Kaplan-Meier curves were used to compare the time to re-attempt between categorical variables. Comparisons were performed using Log-Rank and Wilcoxon tests. Variables with a p-value lower than 0.2 were included in a multivariate Cox regression model. Bivariate logistic regression models were considered to identify risk factors for suicide. The significance level was set to 0.05. RESULTS: Suicide re-attempters were more likely diagnosed with cluster B personality disorders (36.8% vs. 16.6%; p < 0.001), and alcohol use disorders (19.8 vs. 13.9; p = 0.02). Several [1.2% (15/1241)] of them died by suicide. Attempters who suicide were more likely alcohol users (33.3% vs. 17.2%; p = 0.047), and older (50.9 ± 11.9 vs. 40.7 ± 16.0; p = 0.004). CONCLUSIONS: Alcohol use, personality disorders and younger age are risk factors for re-attempting. Older age is a risk factor for suicide among suicide attempters. Current prevention programs of suicidal behaviour should be tailored to the specific profile of each group.

Mental Health Emergencies in Paediatric Services: Characteristics, Diagnostic Stability and Gender differences.

INTRODUCTION: Child and adolescent psychiatric emergencies have increased in recent years. The main objective of our study is to analyze sociodemographic and clinical characteristics of psychiatric emergencies under 18 years old that came to our hospital. Secondary objectives were to study diagnostic stability made in the emergency department and undertake a gender analysis. METHODS: Descriptive cross-sectional study of patients attending the pediatric emergency department who required consultation to psychiatry service during 2010 and 2011, comparing data with two previous cross-sectional cuts (2002-2003 and 2006-2007). Then we track the diagnoses assigned during a year. Statistical analysis was descriptive. We also include a gender analysis. RESULTS: We analyzed 328 episodes corresponding to 179 different patients (average age 14.48). We detected a progressive increase of prevalence of psychiatric emergencies from 2002 to 2011. Diagnostic distribution showed a significant association of Behavioral Disorders with males and an association of Self-injured Behaviors and Eating Disorders with females. The admission rate was 18.5%. One-year diagnostic outcomes showed differences comparing to emergency diagnosis. CONCLUSIONS: Increase and complexity of psychiatric consultations in Pediatric Emergency Department requires a greater coordination and training of these services to enhance patients care. Emergency visit could mean the entrance of complex and severe patients to a specialized care. Our results detect gender differences: more Behavioral Disorders, Psychosis and Substance Use Disorders in males and Self-Injury and Eating Behavior Disorders in females.

Urgencias Psiquiátricas en Pediatría: características, estabilidad diagnóstica y diferencias de género / Mental Health Emergencies in Paediatric Services: Characteristics, Diagnostic Stability and Gender differences

Introducción. Existe una tendencia en los últimos años al aumento de las urgencias infanto-juveniles por motivos psiquiátricos. El objetivo principal del estudio fue analizar las características sociodemográficas y clínicas en las urgencias psiquiátricas de los menores de 18 años. Como objetivos secundarios, estudiamos la estabilidad diagnóstica y realizamos un análisis de género. Metodología. Estudio transversal descriptivo de pacientes que consultaron entre 2010 y 2011 al servicio de urgencias pediátricas por motivos psiquiátricos. Comparamos con dos cortes previos (2002-2003 y 2006-2007) y realizamos un seguimiento al año de los diagnósticos asignados. Estadística descriptiva, incluyendo un análisis comparativo de género. Resultados. Se analizaron 328 episodios (179 pacientes, edad media 14,48 años). Se detecta un incremento de prevalencia de 2002 a 2011. La distribución de diagnósticos por género muestra una asociación significativa de la alteración conductual con el masculino y de las conductas autolesivas y los trastornos alimentarios con el femenino. La tasa de ingreso fue del 18,5%. Tras revisar el diagnóstico al año de seguimiento, muestra diferencias con respecto a la orientación diagnóstica en urgencias. Conclusiones. El incremento de las consultas psiquiátricas urgentes en pediatría requiere una mayor coordinación y formación de los servicios para mejorar y adaptarse a esta emergencia. La consulta urgente supone la puerta de entrada a la atención psiquiátrica especializada de pacientes complejos y graves. Existen diferencias de género relevantes: se observan más trastornos conductuales, psicosis y trastornos por uso de substancias en el género masculino y más conductas autolesivas y trastornos alimentarios en el femenino

Tratamiento antidepresivo y asociación con el ingreso urgente en unidades médicas en pacientes de 65 años o mayores / Association of antidepressant treatment with emergency admission to medical units for patients 65 years or older

Introducción. Existe una creciente evidencia acerca de la interrelación entre presencia de depresión en la tercera edad y riesgo de ingreso hospitalario médico. Objetivo. Determinar el impacto del tratamiento antidepresivo (ATD) como factor protector de ingreso hospitalario desde Urgencias en personas mayores. Método. Se incluyó a personas de 65 años o mayores que acudieron por cualquier motivo a Urgencias de la Corporació Sanitària i Universitària Parc Taulí de Sabadell (Barcelona) entre enero y octubre del 2012. Se obtuvieron datos sociodemográficos básicos, consumo de alcohol y tabaco, antecedentes y tratamiento actual. Se realizó el cálculo de tamaño muestral y una aleatorización simple. Posteriormente se realizó un análisis estadístico descriptivo y pruebas paramétricas. Resultados. Se evaluó a 674 pacientes (53% mujeres), con una edad media de 78,45 años. Un 27,6% de los casos (71% mujeres) recibían tratamiento antidepresivo. Del total de 337 pacientes ingresados (50%), 83 individuos (24,6%) utilizaban previamente ATD, mientras que entre los no ingresados, utilizaban ATD el 30,6%. Tras el análisis comparativo, se objetivó una relación significativa negativa entre recibir ATD y riesgo de ingreso solo en aquellos pacientes de 75 años o mayores (sig. 0,012). Conclusiones. En nuestro estudio, el tratamiento antidepresivo se relaciona con una disminución del riesgo de ingreso hospitalario urgente por enfermedad médica en personas de 75 años o mayores. El tratamiento de la depresión en personas mayores podría tener efecto protector general frente a la severidad de las enfermedades atendidas en Urgencias en nuestra población y puede suponer un criterio de calidad en orden a prevenir complicaciones (AU)

Introduction. There is increasing evidence relating the presence of depression in seniors and the risk of hospital admission in medical departments from the Emergency Services. Objective. To determine the impact of antidepressant treatment (ATD) as a protective factor for emergency hospitalization in older people. Method. All patients aged 65 and over who required urgent attention for medical reasons at the Emergency Department of the Corporació Sanitària i Universitària Parc Taulí (Sabadell, Barcelona, Spain) for the period between January and October 2012 were included in the study. Sociodemographic variables, alcohol and tobacco use, medical history and psychopharmacological treatment were obtained. The necessary sample size was calculated and a simple randomization was performed. Subsequently, a descriptive statistical analysis and parametric tests were conducted. Results. A total of 674 patients (53% women) were evaluated, with a mean age of 78.45 years, and 27.6% of the cases (71% women) were receiving ATD. Among the 333 admitted patients (50%), 83 individuals (24.6%) had previously received ATD; this contrasts with the 103 cases (30.6%) of prior ATD treatment among the patients who were not admitted. After comparative analysis, the relationship between previous use of ATD and being admitted to hospital was not statistically significant in our global sample. This relationship was only statistically significant among the group aged 75 and over (neg. sig. 0.012). Conclusions. In our study, ATD was associated with a decreased risk of hospital admission for urgent medical conditions in people aged 75 and over. Treating depression may protect the elderly against admission to the Emergency department and may potentially be a quality criterion in preventing complications in this population (AU)

Pharmacogenetic study of the effects of raloxifene on negative symptoms of postmenopausal women with schizophrenia: A double-blind, randomized, placebo-controlled trial.

Several double-blind clinical trials have reported improvement in positive, negative and cognitive symptoms of schizophrenia with raloxifene, a selective receptor estrogen modulator. However, there are some inconsistencies in replicating findings between studies of different countries. The failure to replicate these findings may result from genetic factors that could explain some of the variability in the treatment response. However, pharmacogenetic studies exploring this topic in women with schizophrenia are lacking. We aimed to conduct an exploratory pharmacogenetic analysis of a double-blind, randomized, parallel, placebo-controlled study of 24 weeks' duration of raloxifene aiming to improve negative symptoms in postmenopausal women with schizophrenia. Four single nucleotide polymorphisms (SNPs) were studied: rs9340799, rs2234693 and rs1801132 in the Estrogen Receptor 1 (ESR1) gene, and rs1042597 in the UDP-glucuronosyltransferase 1A8 (UGT1A8) gene. Sixty-five postmenopausal women with schizophrenia (DSM-IV) were randomized to either 60mg/day adjunctive raloxifene (36 women) or adjunctive placebo (29 women). Psychopathological symptoms were assessed at baseline and at weeks 4, 12, and 24 with the Positive and Negative Syndrome Scale (PANSS). Of the four studied SNPs, the rs1042597 variant in the UGT1A8 gene was associated with a different treatment response in negative symptoms with raloxifene treatment, whereas the rs2234693 variant in the ESR1 gene was associated with a distinct response in general psychopathology. In conclusion, our study suggests that genetic variants in UGT1A8 and ESR1 genes modulate the treatment response to adding raloxifene to antipsychotic treatment in postmenopausal women with schizophrenia.

Telephone Management Program for Patients Discharged From an Emergency Department After a Suicide Attempt: A 5-Year Follow-Up Study in a Spanish Population.

AIM: In a previous controlled study, the authors reported on the significant beneficial effects of a telephone intervention program for prevention of suicide attempts by patients for up to 1 year. This study reports the 5-year follow-up data. Outcomes were number of recurrences and time to recurrence. METHOD: The intervention was carried out on patients discharged from the emergency room (ER) following attempted suicide (Sabadell). It consisted of a systematic, 1-year telephone follow-up program: after 1 week, and thereafter at 1-, 3-, 6-, 9-, and 12-month intervals to assess the risk of suicide and encourage adherence to treatment. The population in the control group (Terrassa) received treatment as usual after discharge, without additional telephone contact. RESULTS: The effect of reattempt prevention observed in the first year was not maintained over the long term. CONCLUSION: A telephone management program for patients discharged from an ER after attempted suicide could be considered a useful strategy in delaying further suicide attempts and reducing the rate of reattempts in the first year. However, results showed that the beneficial effects were not maintained at the 5-year follow-up.

Free thyroxine levels are associated with cognitive abilities in subjects with early psychosis.

INTRODUCTION: Subjects with a psychotic disorder show mild to moderate cognitive impairment, which is an important determinant of functional outcome. The underlying biological process of cognitive impairment in psychosis is unclear. We aimed to explore whether hypothalamic-pituitary-thyroid axis hormones or thyroid autoimmunity modulate cognitive functioning in subjects with early psychosis. METHODS: We studied 70 patients with a psychotic disorder (<3years of illness) and a control group of 37 healthy subjects (HS). Plasma levels of thyroid-stimulating hormone (TSH), free thyroxine (FT4) and thyroid-peroxidase (TPO-Abs) and thyroglobulin antibodies (TG-Abs) were determined. Cognitive assessment was performed with the MATRICS Cognitive Consensus Cognitive Battery. We also explored the relationship between thyroid variables and cognition in three subgroups of psychotic patients: psychosis not otherwise specified, affective psychosis (bipolar disorder or schizoaffective disorder) and non-affective psychosis (schizophrenia or schizophreniphorm disorder). RESULTS: In patients with early psychosis, higher FT4 levels (but not TSH or thyroid antibodies) were associated with better cognitive performance in attention/vigilance and overall cognition. The relationship between FT4 levels and the attention/vigilance domain remained significant in a multivariate analysis after adjusting for education level, age, gender, substance use, and benzodiazepine and antipsychotic treatments. We did not find a significant association between FT4 and cognitive performance in HS. In the exploratory analysis by psychotic subtypes, subjects with affective psychosis had increased FT4 levels and better cognitive profile than those with non-affective psychosis. CONCLUSIONS: Our study suggests that FT4 levels are associated with cognitive abilities (attention/vigilance and overall cognition) in individuals with early psychosis.

Lack of confirmation of thyroid endophenotype in Bipolar Disorder Type I and their first-degree relatives.

BACKGROUND: Among the biological factors associated with the development and outcomes in Bipolar Disorder Type I (BD-I), previous studies have highlighted the involvement of both thyroid function and/or auto-immunity, proposing a thyroid endophenotype. The objective of this study was to determine the presence of thyroid alterations in BD-I and their first-degree relatives (FDR). METHODOLOGY: Unselected, cross-sectional case-control study with parallel analysis of individuals affected by BD-I (239), their FD-R (131), and 108 healthy controls. Thyroidal functional abnormalities (TSH and free T4) and thyroidal antibodies (thyroglobulin and thyroperoxidase antibodies) were studied. Assessments were carried out in parallel. The sample was described using arithmetic means, standard deviations, percentages and ranges. Chi-square, Student-t tests, ANOVA and Pearson correlation coefficients were used when indicated. RESULTS: BD-I on actual and/or ever treated with lithium showed significant thyroidal functional abnormalities as compared to their FD-R and healthy controls. This BD-I subgroup showed a significant greater proportion of subjects suffering from subclinical hypothyroidism (22%). The role of gender/lithium interactions was relevant. The groups did not show differences in terms of positivization of thyroidal antibodies. LIMITATIONS: The crosssectional design and the lack of determination of dietary iodine deficiencies and/or thyroidal ecographical controls may be a drawback. CONCLUSIONS: The present study supports previous findings on the effect of lithium treatment on thyroidal functional, but did not support previous findings related to a familial association or endophenotype. In addition, the present study did not support a familial aggregation of thyroidal antibodies positivization in pedegrees of BD-I.

Thyroglobulin antibodies and risk of readmission at one year in subjects with bipolar disorder.

Thyroid autoimmunity has been proposed as an endophenotype for Bipolar Disorder (BD), although its relationship with clinical outcomes remains unclear. We aimed to determine whether thyroid autoimmune status (thyroperoxidase antibodies [TPO-Abs] and thyroglobulin antibodies [TG-Abs]) in BD is associated with a greater risk for readmission at one year. We studied 77 inpatients with BD admitted for an index manic or mixed episode. Serum thyroid antibodies (TPO-Abs and TG-Abs) were determined at admission. We compared the readmission risk at 1 year, based on patients׳ thyroid autoimmunity profile using survival analyses. Cox regression was used to control covariates. TG-Abs+ but not TPO-Abs+ was associated with a lower risk of relapse. The Kaplan-Meier mean estimated survival times were 341.6 days (CI95% 316.4-366.8) for the TG-Abs+ group and 261.9 days (CI95%: 221.8 to 302.0) for the TG-Abs- group. Cox proportional hazards regression indicated that subjects with TG-Abs+ were 3.7 (1/OR=1/0.27) times less likely to get admitted during the follow-up period than those with TG-Abs-. Our study suggests that an autoimmune biomarker in patients with BD (i.e., the presence of TG-Abs) is associated with a lower risk of psychiatric readmission after an index hospitalization for a manic or mixed episode.

Propofol y pentotal como agentes anestésicos en la terapia electroconvulsiva: un estudio retrospectivo en el trastorno depresivo mayor / Propofol and thiopental as anesthetic agents in electroconvulsive therapy: a retrospective study in major depression

Objetivo. Determinar la influencia de la utilización de propofol y pentotal como anestésicos en la terapia electroconvulsiva (TEC), en relación con la duración de la crisis, la dosis eléctrica, la eficacia clínica, el perfil cardiovascular y la aparición de efectos cognitivos. Método. Estudio retrospectivo sobre 127 pacientes que recibieron TEC bilateral como tratamiento de un episodio depresivo mayor. Resultados. La duración media de la convulsión eléctrica en el grupo de propofol fue significativamente más corta que en el de pentotal (21,23 ± 6,09 versus 28,24 ± 6,67 s; p < 0,001). La dosis de estímulo media fue de 348,22 mC en el grupo de propofol y de 238 mC en el grupo de pentotal (p < 0,001). Propofol se asoció a un menor incremento de la tensión arterial. No se encontraron diferencias en la respuesta clínica al tratamiento ni en la aparición de otros efectos adversos. Conclusiones. El anestésico utilizado en la TEC puede determinar diferencias en parámetros como la duración de la crisis o la carga eléctrica aplicada. Sin embargo, estas diferencias no parecen traducirse en la eficacia clínica ni en el patrón de efectos adversos (AU)

Objective. To determine the influence of propofol and thiopental as anesthetics in electroconvulsive therapy (ECT), as regards, seizure duration, electrical charge, clinical efficacy, cardiovascular profile, and presence of adverse cognitive effects. Methods. A retrospective design including 127 patients who received bilateral ECT for the treatment of a major depressive episode. Results. The mean seizure duration in the propofol group was significantly shorter than in the thiopental group (21.23 ± 6.09 versus 28.24 ± 6.67 seconds, P < .001). The mean stimulus charge was 348.22 mC in the propofol group, and 238 mC in the thiopental group (P < .001). Propofol was associated with a lower increase in blood pressure. There were no differences between groups in treatment response or presence of adverse effects. Conclusions. The anesthetic agent used in ECT might determine differences in parameters such as seizure duration or electrical charge. However, this does not seem to be translated into differences in clinical efficacy or the pattern of adverse effects observed (AU)

RESULTS: The mean seizure duration in the propofol group was significantly shorter than in the thiopental group (21.23±6.09 versus 28.24±6.6 7s, P<.001). The mean stimulus charge was 348.22 mC in the propofol group, and 238 mC in the thiopental group (P<.001). Propofol was associated with a lower increase in blood pressure. There were no differences between groups in treatment response or presence of adverse effects. CONCLUSIONS: The anesthetic agent used in ECT might determine differences in parameters such as seizure duration or electrical charge. However, this does not seem to be translated into differences in clinical efficacy or the pattern of adverse effects observed.

Effectiveness of a telephone management programme for patients discharged from an emergency department after a suicide attempt: controlled study in a Spanish population.

OBJECTIVE: To determine the effectiveness over one year of a specific telephone management programme on patients discharged from an emergency department (ED) after a suicide attempt. We hypothesized that the programme will reduce the percentage of patients re-attempting suicide and delay the time between attempts. DESIGN: A multicentre, case-control, population-based study. The effect of the 1-year intervention on the main outcome measures was evaluated with respect to a 1-year baseline period and a control group. SETTING: Two hospitals with distinct catchment areas in Catalonia (Spain). PARTICIPANTS: A total of 991 patients discharged from the ED of either hospital after a suicide attempt during the baseline year and the intervention year. INTERVENTION: The intervention was carried out on patients discharged from the ED for attempted suicide (Sabadell). It consisted of a systematic, one-year telephone follow-up programme: after 1 week, thereafter at 1, 3, 6, 9 and 12-month intervals, to assess the risk of suicide and increasing adherence to treatment. The population in the control group (Terrassa) received treatment as usual after discharge, without additional telephone management. MAIN OUTCOME MEASURES: Time elapsed between initial suicide attempt and subsequent one, and changes in the annual rate of patients who reattempted suicide in the year of the intervention and the preceding one. RESULTS: The telephone management programme delayed suicide reattempts in the intervention group compared to the baseline year (mean time in days to first reattempt, year 2008=346.47, sd=4.65; mean time in days to first reattempt, year 2007=316.46, sd=7.18; P<0.0005; χ²=12.1, df=1) and compared to the control population during the same period (mean time in days to first reattempt, treatment period=346.47, sd=4.65; mean time in days to first reattempt, pre-treatment period=300.36, sd=10.67; P<0.0005; χ²=16.8, df=1). The intervention reduced the rate of patients who reattempted suicide in the experimental population compared to the previous year (Intervention 6% (16/296) v Baseline 14% (39/285) difference 8%, 95% confidence interval 2% to 12%) and to the control population (Intervention 6% (16/296) v Control 14% (31/218) difference 8%, -13% to -2%) LIMITATIONS: One of the main obstacles was the difficulty to contact all patients within the established deadlines. Another limitation of our study was that patients under the age of 18 underwent an intensive intervention in the day hospital, although their number was very small (13/319 in 2008) and did not significantly influence the results. But the main limitation of our study was that it was performed within the EAAD project. This project includes a comprehensive multilevel intervention practically in the same experimental area and aimed at an early diagnosis and treatment of depression, which is the main psychiatric disorder associated with suicide. Moreover, longer-term studies should be encouraged to determine whether such interventions really reduce suicide CONCLUSION: A telephone management programme for patients discharged from an ED after a suicide attempted would be a useful strategy in delaying further suicide attempts and in reducing the rate of reattempts, which is known as the highest risk factor for suicide completion.

Insight, symptomatic dimensions, and cognition in patients with acute-phase psychosis.

AIMS: This study was designed to evaluate the relationship between insight and the severity of psychotic symptomatology in a sample of patients in an acute phase of psychosis, as well as to analyze the relationship between insight and the symptomatic profile of the patient. In addition, the role of general cognitive abilities in this relationship was explored. METHOD: Cross-sectional observational study of 96 acute psychotic adults. To evaluate psychopathology we used the Positive and Negative Syndrome Scale; for insight, the Scale of Unawareness of Mental Disorder; and for general cognitive abilities, the Screen for Cognitive Impairment in Psychiatry. RESULTS: Insight showed significant and moderate positive correlations with positive and general symptoms but not with negative symptoms. In the subgroup with positive symptomatic profile, awareness of the disorder and of the effects of medication were positively associated with severity of positive and general psychotic symptoms. Awareness of social consequences of the disease was positively associated with positive symptoms. In the subgroup with a negative symptomatic profile, awareness of the disorder and of the effects of medication were positively associated with severity of positive and general psychotic symptoms. In this subgroup, these relationships were significantly affected by general cognitive abilities. CONCLUSIONS: Insight was not related with the severity of negative psychotic symptoms. The symptomatic profile of subjects played an important role in determining the relationship between insight and its dimensions and the severity of psychotic symptoms. Cognitive function moderated these relationships only in the negative symptomatic profile.
