Atrial Fibrillation and Dementia: Results from the Sao Paulo Ageing & Health Study

Background: Atrial fibrillation (AF) is a controversial risk factor for dementia. Objective: The objective of this study was to assess the association between AF and dementia in the "Sao Paulo Ageing & Health" (SPAH) study participants. Methods: SPAH is a cross-sectional, population-based study of elderly people living in a deprived neighborhood in Sao Paulo, Brazil. Dementia diagnosis was performed according to the 10/66 study group protocol based on Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. Diagnosis of AF was made using a 12-lead electrocardiogram (ECG) recording, which was assessed by two cardiologists. Data on demographics and cardiovascular risk factors were also obtained. Results: Dementia was diagnosed in 66 (4.3%) and AF in 36 (2.4%) of 1,524 participants with a valid ECG. The crude odds ratio (OR) for dementia in participants with AF was 2.8 (95% confidence interval [CI]: 1.0-8.1; p=0.06) compared with individuals without AF. When analyzing data according to sex, a positive relationship was found in women (OR 4.2; 95% CI: 1.24-15.1; p=0.03). After age-adjustment, however, this association was no longer significant (OR 2.2; 95% CI: 0.6-8.9; p=0.26). Conclusion: There was no independent association between AF and dementia in this sample. The prevalence of AF may be low in this population owing to premature cardiovascular death. (Arq Bras Cardiol 2012;99(6):1108-1114)

The near babylonian speech confusion in early detection of psychosis

It is barely 15 years since, in 1996, the issue theme of Schizophrenia Bulletin (Vol 22, 2) “Early Detection, and Intervention in Schizophrenia” signified the commencement of this field of research. Since that time the field of early detection research has developed rapidly and it may be translated into clinical practice by the introduction of an Attenuated Psychosis Syndrome in Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, (DSM-5) (www.dsm5.org/ProposedRevisions/Pages/proposedrevision.aspx?rid=412#). Attenuated psychotic symptoms (APS) had first been suggested as a clinical predictor of first-episode psychosis by the Personal Assessment and Crisis Evaluation (PACE) Clinic group as part of the ultrahigh risk (UHR) criteria.1 The term ultrahigh risk became broadly accepted for this set of criteria for imminent risk of developing psychosis in the late 1990s. The use of the term “prodrome” for a state characterized by at-risk (AR) criteria was criticized as a retrospective concept inevitably followed by the full-blown disorder.1 Although alternative terms have been suggested, prodrome is still used in prospective studies (eg, prodromally symptomatic, potentially or putatively prodromal, prodrome-like state/symptoms). Some alternative suggestions such as prepsychotic state/symptoms, subthreshold psychotic symptoms, early psychosis, subsyndromal psychosis, hypopsychosis, or subpsychosis were short-lived. Other terms still in use include UHR, at-risk mental state (ARMS), AR, high risk, clinical high risk (CHR), or early and late AR state. Further, the term psychotic-like experiences (PLEs) has recently (re-)entered early detection research. …

Clinical diagnosis of posttraumatic stress disorder after myocardial infarction

BACKGROUND: Clinician-rated large-scale studies estimating the prevalence of posttraumatic stress disorder (PTSD) related to myocardial infarction (MI) and identifying predictors of clinical PTSD are currently lacking. HYPOTHESES: We hypothesized that PTSD is prevalent in post-MI patients and that the subjective experience of the MI determines PTSD status. METHODS: We approached 951 post-MI patients with a questionnaire screening for PTSD symptoms related to their MI. Those responding and meeting a cutoff of PTSD symptom levels were invited to participate in a structured clinical interview to diagnose PTSD following Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. Fear of dying, feelings of helplessness, and severity of pain perceived during the MI were also assessed by visual analog scales. RESULTS: The screening questionnaire was completed by 394 patients, whereby 77 met the cutoff for the interview (8 patients declined the interview). Forty of 394 patients (10.2%) had clinical PTSD (subsyndromal and syndromal forms combined). Younger age (OR 0.95, 95% CI 0.91-0.99), greater fear of dying (OR 2.77, 95% CI 1.28-5.97), and more intense feelings of helplessness (OR 2.97, 95% CI 1.42-6.21) were independent predictors of PTSD status. Perceived pain intensity during MI, sex, type of index MI, left ventricular ejection fraction, number of coronary occlusions, and highest level of total creatinine kinase were not significant predictors. CONCLUSIONS: Clinical PTSD is prevalent in post-MI patients. Demographic and particularly psychological variables related to the subjective experience of the event were stronger predictors of PTSD status than were objective measures of MI severity.

Health of entrepreneurs versus employees in a national representative sample

Prior research has found entrepreneurs to experience significantly higher job control and job demands compared with employees. This suggests that entrepreneurs have so-called active jobs and thus may benefit from positive health consequences. The present research compared entrepreneurs' health with employees' health in a national representative sample with regard to the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) diagnoses of somatic diseases, the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) diagnoses of mental disorders, blood pressure, well-being (life-satisfaction) as well as behavioural health indicators (sick days, physician visits). Entrepreneurs showed significantly lower overall somatic and mental morbidity, lower blood pressure, lower prevalence rates of hypertension, and somatoform disorders, as well as higher well-being and more favourable behavioural health indicators. The results are discussed with regard to the active job hypothesis and recommendations for future research are provided.

Depression among Holocaust survivors : a meta-analytic review

The publication of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) introduced the notion that a life-threatening illness can be a stressor and catalyst for Posttraumatic Stress Disorder (PTSD). Since then a solid body of research has been established investigating the post-diagnosis experience of cancer. These studies have identified a number of short and long-term life changes resulting from a diagnosis of cancer and associated treatments. In this chapter, we discuss the psychosocial response to the cancer experience and the potential for cancer-related distress. Cancer can represent a life-threatening diagnosis that may be associated with aggressive treatments and result in physical and psychological changes. The potential for future trauma through the lasting effects of the disease and treatment, and the possibility of recurrence, can be a source of continued psychological distress. In addition to the documented adverse repercussions of cancer, we also outline the recent shift that has occurred in the psycho-oncology literature regarding positive life change or posttraumatic growth that is commonly reported after a diagnosis of cancer. Adopting a salutogenic framework acknowledges that the cancer experience is a dynamic psychosocial process with both negative and positive repercussions. Next, we describe the situational and individual factors that are associated with posttraumatic growth and the types of positive life change that are prevalent in this context. Finally, we discuss the implications of this research in a therapeutic context and the directions of future posttraumatic growth research with cancer survivors. This chapter will present both quantitative and qualitative research that indicates the potential for personal growth from adversity rather than just mere survival and return to pre-diagnosis functioning. It is important to emphasise however, that the presence of growth and prevalence of resilience does not negate the extremely distressing nature of a cancer diagnosis for the patient and their families and the suffering that can accompany treatment regimes. Indeed, it will be explained that for growth to occur, the experience must be one that quite literally shatters previously held schemas in order to act as a catalyst for change.

Home-based activity program for older people with depressive symptoms: DeLLITE–A randomized controlled trial

PURPOSE We wanted to assess the effectiveness of a home-based physical activity program, the Depression in Late Life Intervention Trial of Exercise (DeLLITE), in improving function, quality of life, and mood in older people with depressive symptoms. METHODS We undertook a randomized controlled trial involving 193 people aged 75 years and older with depressive symptoms at enrollment who were recruited from primary health care practices in Auckland, New Zealand. Participants received either an individualized physical activity program or social visits to control for the contact time of the activity intervention delivered over 6 months. Primary outcome measures were function, a short physical performance battery comprising balance and mobility, and the Nottingham Extended Activities of Daily Living scale. Secondary outcome measures were quality of life, the Medical Outcomes Study 36-item short form, mood, Geriatric Depression Scale (GDS-15), physical activity, Auckland Heart Study Physical Activity Questionnaire, and self-report of falls. Repeated measures analyses tested the differential impact on outcomes over 12 months’ follow-up. RESULTS The mean age of the participants was 81 years, and 59% were women. All participants scored in the at–risk category on the depression screen, 53% had a Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases, Tenth Revision diagnosis of major depression or scored more than 4 on the GDS-15 at baseline, indicating moderate or severe depression. Almost all participants, 187 (97%), completed the trial. Overall there were no differences in the impact of the 2 interventions on outcomes. Mood and mental health related quality of life improved for both groups. CONCLUSION he DeLLITE activity program improved mood and quality of life for older people with depressive symptoms as much as the effect of social visits. Future social and activity interventions should be tested against a true usual care control.

Susceptibility locus on chromosome 1q23-25 for a schizophrenia subtype resembling deficit schizophrenia identified by latent class analysis

Context: Identifying susceptibility genes for schizophrenia may be complicated by phenotypic heterogeneity, with some evidence suggesting that phenotypic heterogeneity reflects genetic heterogeneity. Objective: To evaluate the heritability and conduct genetic linkage analyses of empirically derived, clinically homogeneous schizophrenia subtypes. Design: Latent class and linkage analysis. Setting: Taiwanese field research centers. Participants: The latent class analysis included 1236 Han Chinese individuals with DSM-IV schizophrenia. These individuals were members of a large affected-sibling-pair sample of schizophrenia (606 ascertained families), original linkage analyses of which detected a maximum logarithm of odds (LOD) of 1.8 (z = 2.88) on chromosome 10q22.3. Main Outcome Measures: Multipoint exponential LOD scores by latent class assignment and parametric heterogeneity LOD scores. Results: Latent class analyses identified 4 classes, with 2 demonstrating familial aggregation. The first (LC2) described a group with severe negative symptoms, disorganization, and pronounced functional impairment, resembling “deficit schizophrenia.” The second (LC3) described a group with minimal functional impairment, mild or absent negative symptoms, and low disorganization. Using the negative/deficit subtype, we detected genome-wide significant linkage to 1q23-25 (LOD = 3.78, empiric genome-wide P = .01). This region was not detected using the DSM-IV schizophrenia diagnosis, but has been strongly implicated in schizophrenia pathogenesis by previous linkage and association studies.Variants in the 1q region may specifically increase risk for a negative/deficit schizophrenia subtype. Alternatively, these results may reflect increased familiality/heritability of the negative class, the presence of multiple 1q schizophrenia risk genes, or a pleiotropic 1q risk locus or loci, with stronger genotype-phenotype correlation with negative/deficit symptoms. Using the second familial latent class, we identified nominally significant linkage to the original 10q peak region. Conclusion: Genetic analyses of heritable, homogeneous phenotypes may improve the power of linkage and association studies of schizophrenia and thus have relevance to the design and analysis of genome-wide association studies.

Suicidal behaviour in bipolar disorder

The Jorvi Bipolar Study (JoBS) is a collaborative ongoing bipolar research project between the Department of Mental Health and Alcohol Research of the National Public Health Institute, Helsinki, and the Department of Psychiatry, Jorvi Hospital, Helsinki University Central Hospital (HUCH), Espoo, Finland. The JoBS is a prospective, naturalistic cohort study of secondary level care psychiatric out-and inpatients with a new episode of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) bipolar disorder (BD). Altogether, 1630 patients (aged 18-59) years were screened using the Mood Disorder Questionnaire (MDQ) for a possible new episode of DSM-IV BD. 490 patients were interviewed with semi-structured interview [the Structured Clinical Interview for DSM-IV Disorders, research version with Psychotic Screen (SCID-I/P)]. 191 patients with new episode of DSM-IV BD were included in the bipolar cohort study. Psychiatric comorbidity was evaluated using semi-structured interviews. At 6- and 18-month follow-up, the interviews were repeated and life-chart methodology was used to integrate all available information about nature and duration of all different phases. Suicidal behaviour was examined both at intake and follow-up by psychometric scale [Scale for Suicidal Ideation (SSI)], interviewer s questions and medical and psychiatric records. The aim of this thesis was to evaluate prevalence of suicidal behaviour and incidence of suicide attempts, and examine the wide range of risk factors for attempted suicide both, at intake and follow-up, in representative secondary-level sample of psychiatric in- and outpatients with BD. In this study suicidal behaviour was common among psychiatric patients with BD. During the episode when patients were included into cohort study (index episode), 20% of the patients had attempted suicide and 61% had suicidal ideation. Severity of depressive episode and hopelessness were independent risk factors for suicidal ideation, whereas hopelessness, comorbid personality disorder and previous suicide attempt predicted suicide attempts during the index episode. There were no differences in prevalence of suicidal behaviour between bipolar I and II disorder; the risk factors were overlapping but not identical. During the index episode, suicide attempts took place during depressive, mixed and depressive mixed phases. Furthermore, there were marked differences regarding level of suicidal ideation during different phases, with the highest levels during the mixed phases of the illness. Hopelessness was independently associated with suicidal behaviour during the depressive phase. A subjective rating of severity of depression (Beck Depression Inventory) and younger age predicted suicide attempts during mixed phases. During the 18-month follow-up 20% of patients attempted suicide. Previous suicide attempts, hopelessness, depressive phase at index episode and younger age at intake were independent risk factors for suicide attempts during follow-up. Taken altogether, 55% patients attempted suicide before index episode, during index episode or during follow-up. The incidence of suicide attempts was 37-fold during combined mixed and depressive mixed states and 18-fold during major depressive phase as compared with other phases. Prior suicide attempt and time spent in combined mixed phases - mixed and depressive mixed - and depressive phases independently predicted the suicide attempt during follow-up. More than half of the patients have attempted suicide during their lifetime, a finding which highlights the public health importance of suicidal behaviour in bipolar disorder. Clinically, it is crucial to recognize BD and manage the mixed and depressive phases of bipolar patients fast and effectively, as time spent in depressive and mixed phases involves a remarkably high risk of suicide attempts.

Sociologia do trauma: elementos sociogenéticos e psicogenéticos

O presente trabalho investiga os diferentes processos sociais relacionados ao surgimento do transtorno de estresse pós-traumático (TEPT) no contexto brasileiro. Categoria diagnóstica norte-americana instituída na década de 1980 pela terceira edição do Manual Diagnóstico e Estatístico de Transtornos Mentais (Diagnostic and Statistical Manual of Mental Disorders DSM-III) uma publicação da Associação Americana de Psiquiatria (American Psychiatric Association APA) o TEPT tornou-se, desde a sua aparição, uma das categorias nosológicas mais difundidas, estudadas e diagnosticadas da psiquiatria contemporânea. A partir do cotidiano de um laboratório de pesquisa e tratamento do TEPT, de análises conversacionais dos atendimentos médicos, de um estudo das diferentes escalas psiquiátricas utilizadas no acompanhamento dos pacientes e de pesquisas sobre a mídia relacionada às experiências traumáticas buscou-se entender os entrelaçamentos entre os processos de difusão e a construção da legitimidade da categoria diagnóstica do TEPT. A abordagem aqui proposta pretende ir além do aparente dilema entre uma concepção medicalizada que assumem a existência o TEPT como um fenômeno natural e as abordagens sócio-antropológicas que veem o TEPT como uma experiência culturalmente construída. Por fim, pretendo mostrar, pela investigação dos alicerces políticos e culturais dos denominados transtornos mentais, que o estatuto social dos diagnósticos e dos tratamentos da moderna psiquiatria só pode ser compreendido tendo como referência as dinâmicas de longo prazo nas sociedades contemporâneas.

Eficacia de las intervenciones psicoeducativas en pacientes con esquizofrenia: una revisión sistemática

Introducción: La esquizofrenia es una enfermedad crónica que genera deterioro cognitivo y diversos grados de discapacidad. Dentro del tratamiento no solo debe considerarse el abordaje farmacológico sino también un enfoque psicoterapéutico. La psicoeducación es una intervención terapéutica con alto potencial en el manejo de pacientes con esquizofrenia, tiene importantes resultados especialmente en el área cognitiva. Métodos: Revisión sistemática de la literatura de artículos de bases de datos y búsqueda manual de revistas relacionadas que aportaran la mejor evidencia. Se evaluó calidad metodológica de los estudios y estos se organizaron en tablas de evidencia. Resultados: De 34 artículos potenciales, se seleccionaron finalmente dos para ser incluidos en la revisión. Se clasificaron como nivel de evidencia I. A pesar de la ambigüedad de las comparaciones, en general, las intervenciones psicoeducativas aportan beneficios con disminución de recaídas y reingresos hospitalarios. Discusión: La amplia gama de comparaciones aportó complejidad en el momento de incluir estudios para la presente revisión, la falta de detalle sobre aspectos propios de la intervención utilizada en cada estudio, generó limitaciones al momento de realizar comparaciones. La psicoeducación aporta beneficios, sin embargo debe tenerse en cuenta el compromiso cognitivo propio de la enfermedad, al momento de evaluar los desenlaces de este tipo de intervenciones. Conclusión: Las intervenciones psicoeducativas juegan un importante papel en el tratamiento de los pacientes con esquizofrenia. Es necesaria la realización de más estudios que consoliden con mayor firmeza la evidencia científica en éste área en particular.

Estudio de asociación entre genotipo de DAT1 y transtorno por déficit de atención / hiperactividad

Introducción: El TDAH tiene un componente genético importante; el gen de transportador de Dopamina (DAT1) se ha asociado con susceptibilidad al TDAH y con sus endofenotipos. El VNTR de 40pb en la región 3’UTR aumenta la expresión del DAT1. En Colombia no hay ningún estudio previo que indique evidencia de la asociación genética entre TDAH y el gen DAT1. Objetivo: Determinar asociación entre el VNTR del DAT1 y el fenotipo y/o endofenotipos del TDAH. Métodos: Se seleccionaron 73 pacientes con TDAH y 75 controles, se valoró en los casos inteligencia y funciones ejecutivas. Mediante (PCR) se amplificó el VNTR DAT1. Se establecieron estadísticos genético poblacionales, análisis de asociación y de regresión logística entre las pruebas neuropsicológicas y genotipo. Resultado: El polimorfismo del DAT1 no mostró asociación con TDAH, ni con alteraciones en las funciones ejecutivas. El genotipo 10/10 del VNTR DAT1 se encontró asociado con el índice de velocidad de procesamiento (p <0,05). En el subgrupo hiperactividad hubo asociación con algunas subpruebas de flexibilidad cognitiva, número de respuestas correctas, total de errores, número de respuestas perseverativas (p ≤ 0.01). En el subgrupo mixto se asoció con índice de comprensión verbal (p <0,05). Conclusiones: No hubo asociación entre el polimorfismo VNTR (DAT1) y el fenotipo de TDAH. Se encontraron asociaciones entre genotipo y algunos test de flexibilidad cognitiva e índice de comprensión verbal. Se establecieron los estadísticos genético poblacionales de este polimorfismo para la población analizada, el cual corresponde al primer reporte de una muestra de nuestro país.

Perfil neuropsicológico de personas adultas con VIH/SIDA

Los déficit neurológicos en el virus de inmunodeficiencia humana VIH, específicamente las alteraciones en el funcionamiento cognitivo, han estado presentes desde el inicio de su propagación y han sido una de las principales manifestaciones a lo largo de todas las etapas del virus. No obstante, gracias a los avances de la terapia antirretroviral se ha dado un aumento de la expectativa de vida de los pacientes, dándose de la misma manera un incremento en los déficits anteriormente mencionados. El objetivo del presente estudio es describir el perfil neuropsicológico de los pacientes con VIH y establecer si existen relaciones entre las funciones que se encuentren deterioradas, el tiempo de diagnóstico y la terapia antiretroviral. Para esto se llevo a cabo un estudio descriptivo de tipo exploratorio con el fin de medir las características de las funciones neuropsicológicas en un grupo de 24 pacientes pertenecientes al programa especial B24 del Hospital Universitario Mayor y Hospital de Barrios Unidos MÉDERI en Bogotá, Colombia. Para esto, se utilizó un protocolo de pruebas neuropsicológicas: Mini Mental StateExamination (MMSE), WAIS-III (sub-pruebas dígitos, letras y números, aritmética y semejanzas), Curva de aprendizaje auditivo verbal de Rey (RAVLT), WMS-III (sub-pruebas de recobro de historias y Localización), TMT A y B, Set Test de Isaacs, Figura Compleja de Rey y Test de Stroop. Dentro de los resultados se encontró que la medida de edad fue de 50 con un total de 19 hombres y 5 mujeres. Las funciones con mayor predominio de deterioro fueron la atención sostenida y alternante, la memoria declarativa, las funciones ejecutivas (específicamente en el control inhibitorio) y la velocidad de procesamiento, los pacientes presentan un rango de deterioro cognitivo leve (GDS 3). Se concluyó que el perfil de deterioro es mixto y que es necesario ampliar la muestra para obtener resultados más precisos en cuanto a las diferencias de acuerdo al tiempo de diagnóstico y la terapia antiretroviral.

Inteligencia emocional y afrontamiento del estrés

El objetivo principal de este trabajo es realizar una revisión teórica de los estudios que han elaborado un análisis acerca de la Inteligencia Emocional con la capacidad para afrontar situaciones generadoras de estrés. Los diferentes estudios muestran que niveles altos en Inteligencia Emocional se relacionan con estrategias de afrontamiento basadas en el análisis y resolución de conflictos, mientras que niveles bajos de inteligencia emocional se relacionan con estrategias de afrontamiento basadas en la evitación, la superstición, y la resistencia al cambio. La evidencia que arrojan los estudios indican que la inteligencia emocional es fundamental en el autocontrol emocional y en la habilidad de adaptación de los individuos para afrontar situaciones generadoras de estrés.

Eficacia de la estimulación magnética transcraneal en la disminución de severidad en el trastorno depresivo mayor en monoterapia y coadyuvante comparado con tratamientos farmacológicos. Revisión sistemática y meta-análisis

Resumen Introducción Una posible opción de tratamiento para el manejo del trastorno depresivo mayor (TDM) es la estimulación magnética transcraneal (EMT) que ha mostrado propiedades antidepresivas superiores al placebo con un buen perfil de seguridad. El objetivo del presente trabajo es determinar la reducción en la severidad del TDM y la proporción de eventos adversos (EA) en pacientes con TDM refractario y no refractario, posterior al uso de EMT administrada en monoterapia o tratamiento coadyuvante comparado con terapia farmacológica. Metodología Se planteó una pregunta PICOT de la cual se realizó una búsqueda sistemática de estudios clínicos en las bases de datos Medline, EMBASE y Cochrane. Dos investigadores en forma independiente realizaron la selección de artículos, evaluación de calidad con la herramienta de la colaboración Cochrane y extracción de datos. Se extrajeron datos de eficacia como tasa de respuesta, porcentaje de remisión, calidad de vida, diminución sintomática del trastorno depresivo mayor en la escala de Hamilton y capacidad funcional. Igualmente, proporción de pacientes con EA. Se realizó un meta-análisis de estas variables teniendo en cuenta la heterogeneidad. Resultados La presente revisión sistemática incluyó 26 estudios clínicos aleatorizados de baja calidad metodológica mostrando que la EMT presentó una eficacia superior cuando es usada como coadyuvante a las terapias con que venían siendo tratados los pacientes con TDM refractario y no refractario en los desenlaces de tasa de respuesta y porcentaje de remisión. En el caso de intervenciones farmacológicas específicas, la EMT presento eficacia similar, tanto en terapia coadyuvante como en monoterapia comparado con las intervenciones farmacológicas. En cuanto a seguridad, la EMT presenta un buen perfil de seguridad debido a que en todos los escenarios estudiados los EA fueron no serios y baja frecuencia Conclusiones La evidencia disponible sugiere que la EMT mostró ser efectivo y seguro para el manejo del TDM refractario y no refractario. Sin embargo, la evidencia es débil por lo tanto se necesita mayor investigación clínica que soporte su uso.
