Group cognitive-behavioral therapy versus selective serotonin reuptake inhibitors for obsessive-compulsive disorder: A practical clinical trial

Clinical effectiveness of group cognitive-behavioral therapy (GCBT) versus fluoxetine in obsessive-compulsive disorder outpatients that could present additional psychiatric comorbidities was assessed. Patients (18-65 years; baseline Yale-Brown Obsessive-Compulsive-Scale [Y-BOCS] scores >= 16; potentially presenting additional psychiatric comorbidities) were sequentially allocated for treatment with GCBT (n = 70) or fluoxetine (n = 88). Mean Y-BOCS scores decreased by 23.13% in the GCBT and 21.54% in the SSRI groups (p = 0.875). Patients presented a mean of 2.7 psychiatric comorbidities. and 81.4% showed at least one additional disorder. A reduction of at least 35% in baseline Y-BOCS scores and CGI ratings of 1 (much better) or 2 (better) was achieved by 33.3% of GCBT patients and 27.7% in the SSRI group (p = 0.463). The Y-BOCS reduction was significantly lower in patients with one or more psychiatric comorbidities (21.15%, and 18.73%, respectively) than in those with pure OCD (34.62%; p = 0.034). Being male, having comorbidity of Major Depression, Social Phobia, or Dysthymia predicted a worse response to both treatments. Response rates to both treatments were similar and lower than reported in the literature, probably due to the broad inclusion criteria and the resulting sample more similar to the real world population.

Gray Matter Volumes in Obsessive-Compulsive Disorder Before and After Fluoxetine or Cognitive-Behavior Therapy: A Randomized Clinical Trial

Serotonin reuptake inhibitors and cognitive-behavior therapy (CBT) are considered first-line treatments for obsessive-compulsive disorder (OCD). However, little is known about their modulatory effects on regional brain morphology in OCD patients. We sought to document structural brain abnormalities in treatment-naive OCD patients and to determine the effects of pharmacological and cognitive-behavioral treatments on regional brain volumes. Treatment-naive patients with OCD (n = 38) underwent structural magnetic resonance imaging scan before and after a 12-week randomized clinical trial with either fluoxetine or group CBT. Matched-healthy controls (n = 36) were also scanned at baseline. Voxel-based morphometry was used to compare regional gray matter (GM) volumes of regions of interest (ROIs) placed in the orbitofrontal, anterior cingulate and temporolimbic cortices, striatum, and thalamus. Treatment-naive OCD patients presented smaller GM volume in the left putamen, bilateral medial orbitofrontal, and left anterior cingulate cortices than did controls (p<0.05, corrected for multiple comparisons). After treatment with either fluoxetine or CBT (n = 26), GM volume abnormalities in the left putamen were no longer detectable relative to controls. ROI-based within-group comparisons revealed that GM volume in the left putamen significantly increased (p<0.012) in fluoxetine-treated patients (n = 13), whereas no significant GM volume changes were observed in CBT-treated patients (n = 13). This study supports the involvement of orbitofronto/cingulo-striatal loops in the pathophysiology of OCD and suggests that fluoxetine and CBT may have distinct neurobiological mechanisms of action.

Brief Cognitive Behavioral Intervention in Groups in a Brazilian Assisted Reproduction Program

The study's objective was to assess the effect of a cognitive behavioral group intervention on the pregnancy rates of patients submitted to in vitro fertilization (IVF) techniques or to intracytoplasmic sperm injection (ICSI). The study was conducted on 188 patients, 93 who participated in a group of psychological intervention before the IVF and ICSI procedures and 95 patients submitted to IVF and ICSI during the same period of time, who did not participate in the intervention (control group). Clinical pregnancy was the outcome measure. Demographic and clinical variables were compared between groups in order to assess the group's homogeneity. Participants in the psychological intervention obtained a pregnancy rate of 39.8%, significantly higher than the 23.2% rate of nonparticipants (chi(2) = 6.03, p =.01, odds ratio of 22 (CI: 1.16-4.13). The data suggest that group psychological intervention before IVF and ICSI in order to control stress seems to increase the rate of success of these procedures.

Traumatic memories: bridging the gap between functional neuroimaging and psychotherapy

Objective: Neuroimaging studies have highlighted important issues related to structural and functional brain changes found in sufferers of psychological trauma that may influence their ability to synthesize, categorize, and integrate traumatic memories. Methods: Literature review and critical analysis and synthesis. Results: Traumatic memories are diagnostic symptoms of post-traumatic stress disorder (PTSD), and the dual representation theory posits separate memory systems subserving vivid re-experiencing (non-hippocampally dependent) versus declarative autobiographical memories of trauma (hippocampally dependent). But the psychopathological signs of trauma are not static over time, nor is the expression of traumatic memories. Multiple memory systems are activated simultaneously and in parallel on various occasions. Neural circuitry interaction is a crucial aspect in the development of a psychotherapeutic approach that may favour an integrative translation of the sensory fragments of the traumatic memory into a declarative memory system. Conclusion: The relationship between neuroimaging findings and psychological approaches is discussed for greater efficacy in the treatment of psychologically traumatized patients.

Does anti-obsessional pharmacotherapy treat so-called comorbid depressive and anxiety states?

Background: Obsessive-compulsive disorder (OCD) is a chronic condition that normally presents high rates of psychiatric comorbidity. Depression, tic disorders and other anxiety disorders are among the most common comorbidities in OCD adult patients. There is evidence that the higher the number of psychiatric comorbidities, the worse the OCD treatment response. However, little is known about the impact of OCD treatment on the outcome of the psychiatric comorbidities usually present in OCD patients. The aim of this study was to investigate the impact of exclusive, conventional treatments for OCD on the outcome of additional psychiatric disorders of OCD patients, detected at baseline. Methods: Seventy-six patients with primary OCD admitted to the treatment protocols of the Obsessive-Compulsive Spectrum Disorders Program between July 2007 and December 2009 were evaluated at pre-treatment and after 12 months. Data were analyzed to verify possible associations between,OCD treatment response and the outcome of psychiatric comorbidities. Results: Results showed a significant association between OCD treatment response and improvement of major depression and dysthymia (p-value = 0.002), other anxiety disorders (generalized anxiety disorder, social phobia, specific phobia, posttraumatic stress disorder, panic disorder, agoraphobia and anxiety disorder not otherwise specified) (p-value = 0.054) and tic disorders (p-value = 0.043). Limitations: This is an open, non-blinded study, without rating scales for comorbid conditions. Further research is necessary focusing on the possible mechanisms by which OCD treatment could improve these specific disorders. Conclusions: Our results suggest that certain comorbid disorders may benefit from OCD-targeted treatment. (C) 2012 Elsevier B.V. All rights reserved.

Neuropsychological predictors of response to randomized treatment in obsessive-compulsive disorder

Objective: To identify neuropsychological predictors of treatment response to cognitive-behavioral therapy (CBT) and fluoxetine in treatment-naive adults with obsessive-compulsive disorder (OCD). Method: Thirty-eight adult outpatients with OCD underwent neuropsychological assessment, including tasks of intellectual function, executive functioning and visual and verbal memory, before randomization to a 12-week clinical trial of either CBT or fluoxetine. Neuropsychological measures were used to identify predictors of treatment response in OCD. Results: Neuropsychological measures that predicted a better treatment response to either CBT or fluoxetine were higher verbal IQ (Wechsler Abbreviated Scale of Intelligence) (p = 0.008); higher verbal memory on the California Verbal Learning Test (p = 0.710); shorter time to complete part D (Dots) (p<0.001), longer time to complete part W (Words) (p = 0.025) and less errors on part C (Colors) (p<0.001) in the Victoria Stroop Test (VST). Fewer perseverations on the California Verbal Learning Test, a measure of mental flexibility, predicted better response to CBT, but worse response to fluoxetine (p = 0.002). Conclusion: In general, OCD patients with better cognitive and executive abilities at baseline were more prone to respond to either CBT or fluoxetine. Our finding that neuropsychological measures of mental flexibility predicted response to treatment in opposite directions for CBT and fluoxetine suggests that OCD patients with different neuropsychological profiles may respond preferentially to one type of treatment versus the other. Further studies with larger samples of OCD patients are necessary to investigate the heuristic value of such findings in a clinical context. (C) 2012 Elsevier Inc. All rights reserved.

Clinical predictors of long-term outcome in obsessive-compulsive disorder

Background: The purpose of this study was to investigate demographic and clinical factors associated with the long-term outcome of obsessive-compulsive disorder (OCD). Methods: A hundred ninety-six previously untreated patients with DSM-IV criteria OCD completed a 12-week randomized open trial of group cognitive-behavioral therapy (GCBT) or fluoxetine, followed by 21 months of individualized, uncontrolled treatment, according to international guidelines for OCD treatment. OCD severity was assessed using the Yale–Brown Obsessive-Compulsive Scale (Y-BOCS) at different times over the follow-up period. Demographics and several clinical variables were assessed at baseline. Results: Fifty percent of subjects improved at least 35% from baseline, and 21.3% responded fully (final Y-BOCS score < or = 8). Worse prognosis was associated with earlier age at onset of OCD (P = 0.045), longer duration of illness (P = 0.001) presence of at least one comorbid psychiatric disorder (P = 0.001), comorbidity with a mood disorder (P = 0.002), higher baseline Beck-Depression scores (P = 0.011), positive family history of tics (P = 0.008), and positive family history of anxiety disorders (P = 0.008). Type of initial treatment was not associated with long-term outcome. After correction for multiple testing, the presence of at least one comorbid disorder, the presence of a depressive disorder, and duration of OCD remained significant. Conclusions: Patients under cognitive-behavioral or pharmacological treatment improved continuously in the long run, regardless of initial treatment modality or degree of early response, suggesting that OCD patients benefit from continuous treatment. Psychiatric comorbidity, especially depressive disorders, may impair the long-term outcome of OCD patients.

Efficacy of graded activity versus supervised exercises in patients with chronic non-specific low back pain: protocol of a randomised controlled trial

Abstract Background Low back pain is a relevant public health problem, being an important cause of work absenteeism worldwide, as well as affecting the quality of life of sufferers and their individual functional performances. Supervised active physical routines and of cognitive-behavioral therapies are recommended for the treatment of chronic Low back pain, although evidence to support the effectiveness of different techniques is missing. Accordingly, the aim of this study is to contrast the effectiveness of two types of exercises, graded activity or supervised, in decreasing symptoms of chronic low back pain. Methods/design Sample will consist of 66 patients, blindly allocated into one of two groups: 1) Graded activity which, based on an operant approach, will use time-contingent methods aiming to increase participants’ activity levels; 2) Supervised exercise, where participants will be trained for strengthening, stretching, and motor control targeting different muscle groups. Interventions will last one hour, and will happen twice a week for 6 weeks. Outcomes (pain, disability, quality of life, global perceived effect, return to work, physical activity, physical capacity, and kinesiophobia) will be assessed at baseline, at treatment end, and three and six months after treatment end. Data collection will be conducted by an investigator blinded to treatment allocation. Discussion This project describes the randomisation method that will be used to compare the effectiveness of two different treatments for chronic low back pain: graded activity and supervised exercises. Since optimal approach for patients with chronic back pain have yet not been defined based on evidence, good quality studies on the subject are necessary. Trial registration NCT01719276

Development of an integrative cessation program for co-smokers of cigarettes and cannabis: demand analysis, program description, and acceptability

Abstract Background Tobacco and cannabis use are strongly interrelated, but current national and international cessation programs typically focus on one substance, and address the other substance either only marginally or not at all. This study aimed to identify the demand for, and describe the development and content of, the first integrative group cessation program for co-smokers of cigarettes and cannabis. Methods First, a preliminary study using expert interviews, user focus groups with (ex-)smokers, and an online survey was conducted to investigate the demand for, and potential content of, an integrative smoking cessation program (ISCP) for tobacco and cannabis co-smokers. This study revealed that both experts and co-smokers considered an ISCP to be useful but expected only modest levels of readiness for participation.Based on the findings of the preliminary study, an interdisciplinary expert team developed a course concept and a recruitment strategy. The developed group cessation program is based on current treatment techniques (such as motivational interviewing, cognitive behavioural therapy, and self-control training) and structured into six course sessions.The program was evaluated regarding its acceptability among participants and course instructors. Results Both the participants and course instructors evaluated the course positively. Participants and instructors especially appreciated the group discussions and the modules that were aimed at developing personal strategies that could be applied during simultaneous cessation of tobacco and cannabis, such as dealing with craving, withdrawal, and high-risk situations. Conclusions There is a clear demand for a double cessation program for co-users of cigarettes and cannabis, and the first group cessation program tailored for these users has been developed and evaluated for acceptability. In the near future, the feasibility of the program will be evaluated. Trial registration Current Controlled Trials ISRCTN15248397

OBJETIVO: Identificar modelos de intervenções psicoeducacionais e os seus efeitos em cuidadores de idosos com demência. MÉTODOS: Levantamento de estudos publicados entre janeiro de 2000 e abril de 2012 nas bases de dados PubMed, Web of Knowledge, Lilacs e SciELO, utilizando as seguintes palavras-chave "psychoeducational and caregiver", "cuidador e demência e psicoeducação" e "cuidador e intervenção". Apenas os artigos que denominavam a intervenção estudada como psicoeducação fazem parte do presente estudo. RESULTADOS: Foram encontrados 27 artigos com relatos acerca do impacto de intervenções psicoeducacionais em cuidadores de idosos com demência. Os resultados mais prevalentes desses estudos são: melhora do bem-estar dos cuidadores (37% dos estudos); aumento do uso de estratégias de enfrentamento (30%); diminuição de pensamentos disfuncionais (30%); aumento do conhecimento sobre os serviços disponíveis (19%); melhora da autoeficácia (15%); e aumento de habilidades para o cuidado (11%). A abordagem psicoeducacional descrita nos estudos é do âmbito informativo, cognitivo-comportamental, com técnicas de gerenciamento de estresse e de emoções; técnicas de resolução de problemas e apoio emocional. CONCLUSÃO: A intervenção psicoeducacional contribui significativamente para a melhora do bem-estar do cuidador, contudo ainda é necessária uma padronização dessa abordagem, em termos de estrutura, duração e conteúdos ministrados, para que haja evidências mais precisas do efeito desse tipo de intervenção.

Cognitive, Mood, and Electroencephalographic Effects of Noninvasive Cortical Stimulation With Weak Electrical Currents

Objectives: The use of noninvasive cortical electrical stimulation with weak currents has significantly increased in basic and clinical human studies. Initial, preliminary studies with this technique have shown encouraging results; however, the safety and tolerability of this method of brain stimulation have not been sufficiently explored yet. The purpose of our study was to assess the effects of direct current (DC) and alternating current (AC) stimulation at different intensities in order to measure their effects on cognition, mood, and electroencephalogram. Methods: Eighty-two healthy, right-handed subjects received active and sham stimulation in a randomized order. We conducted 164 ninety-minute sessions of electrical stimulation in 4 different protocols to assess safety of (1) anodal DC of the dorsolateral prefrontal cortex (DLPFC); (2) cathodal DC of the DLPFC; (3) intermittent anodal DC of the DLPFC and; (4) AC on the zygomatic process. We used weak currents of 1 to 2 mA (for DC experiments) or 0.1 to 0.2 mA (for AC experiment). Results: We found no significant changes in electroencephalogram, cognition, mood, and pain between groups and a low prevalence of mild adverse effects (0.11% and 0.08% in the active and sham stimulation groups, respectively), mainly, sleepiness and mild headache that were equally distributed between groups. Conclusions: Here, we show no neurophysiological or behavioral signs that transcranial DC stimulation or AC stimulation with weak currents induce deleterious changes when comparing active and sham groups. This study provides therefore additional information for researchers and ethics committees, adding important results to the safety pool of studies assessing the effects of cortical stimulation using weak electrical currents. Further studies in patients with neuropsychiatric disorders are warranted.

Elderly Individuals with Diabetes: Adding Cognitive Training to Psychoeducational Intervention

The present research examined the effects of a cognitive training program combined with psychoeducational intervention for diabetic elderly patients. Specifically, it aimed at assessing the effects of an eight-session cognitive training and educational program in diabetic elderly individuals and investigating changes in their awareness about specific aspects of diabetes. The final sample consisted of 34 individuals-19 in the experimental group (EG) and 15 in the control group (CG), all residing in the eastern region of the city of Sao Paulo. The protocol included clinical and sociodemographic questions; the Diabetes Attitudes Questionnaire (ATT-19); Diabetes Knowledge Scale (DKN-A); Mini Mental State Examination (MMSE); Verbal Fluency-animal category (VF); Geriatric Depression Scale (GDS); Short Cognitive Performance Test (SKT); and the Rivermead Behavioral Memory Test (RBMT). Results pointed to a significant difference between the two groups for the ATT-19, DKN, and SKT-memory and SKT-total, and a marginally significant difference for the RBMT history in the posttest. As for the remaining cognitive variables, no changes were observed. Retest effects were not observed in the CG. We concluded that cognitive training combined with psychoeducational intervention in diabetic elderly individuals may be effective in producing cognitive gains as well as attitude and knowledge improvement concerning diabetes mellitus (DM).

Discourse and bipolar disorder: Narrative therapy on northeast Brazil

Background: The expression 'bipolar disorder' refers to any of several psychological disorders of mood that alternate episodes of depression and mania. Also called manic depression or manic-depressive illness, it is a relatively common but unknown pathology that brings some stigmas for patients and provokes deleterious effects for their lives. This research aimed to comprehend actions, behaviors and emotions involved with bipolar disorder, through narratives of patient's personal and familiar histories. Methods: We surveyed 30 patients from a psychiatric service located in Aparecida, Paraiba, Brazil. Selected patients had bipolar disorder according to DSM-IV. For data collection, we used non-structured interview, approaching specific aspects related to bipolar disorder. Quantitative and qualitative analysis were done and Hamilton Rating Scale for Depression (HAMD) was used. Results: Most of patients presented depressive actions associated with moderate euphoria. 11 of them related familiar history of psychopathology. Mania and hippomania were prevalent on male gender, while psychotic symptoms overlay ate female. Conclusion: Patients lack a translation of behavioral and temperamental processes to minimize harm caused to their lives.

Normative Data for Healthy Middle-Aged and Elderly Performance on the Addenbrooke Cognitive Examination-Revised

Objective: To provide normative data for healthy middle-aged and elderly Brazilians' performance on the Addenbrooke Cognitive Examination-Revised (ACE-R) and to investigate the effects of age, sex, and schooling on test performance. Background: The ACE-R is a brief cognitive battery that assesses various aspects of cognition. Its 5 subdomains (Attention and Orientation, Memory, Verbal Fluency, Language, and Visuospatial Abilities) are commonly impaired in Alzheimer disease or frontotemporal dementia. Methods: We evaluated 144 cognitively healthy volunteers (50% men, 50% women) aged 50 to 93 years, with 4 to 24 years of schooling. We divided the participants into 4 age groups, each of which was then stratified into 3 groups according to years of education. We assessed all participants with the ACE-R, the Mattis Dementia Rating Scale, and the Cornell Scale for Depression in Dementia. Results: Years of education affected all ACE-R subscores. Age influenced the Verbal Fluency subscore (P < 0.001) and the ACE-R total score (P < 0.05). Sex affected the Attention and Orientation (P = 0.037) and Mini-Mental State Examination subscores (P = 0.048), but not the ACE-R total score (P > 0.05). Conclusions: The performance of healthy middle-aged and elderly individuals on the ACE-R battery is strongly influenced by education and, to a lesser extent, by age. These findings are of special relevance in countries with populations that have marked heterogeneity in educational levels.
