Cannabidiol for the treatment of crack-cocaine craving: an exploratory double-blind study

Objective: To assess the efficacy of cannabidiol (CBD) in the management of crack-cocaine craving and the treatment of frequent withdrawal symptoms. Methods: Thirty-one men with a diagnosis of crack-cocaine dependence were enrolled in a randomized, double-blind, placebo-controlled trial. We applied neuropsychological tests and assessed craving intensity, anxiety and depression symptoms, and substance use patterns at baseline and at the end of the trial. The participants were treated with CBD 300 mg/day or placebo for 10 days. During this period, we used a technique to induce craving and assessed the intensity of symptoms before and after the induction procedure. Results: Craving levels reduced significantly over the 10 days of the trial, although no differences were found between the CBD and placebo groups. Craving induction was successful in both groups, with no significant differences between them. Indicators of anxiety, depression, and sleep alterations before and after treatment also did not differ across groups. Conclusion: Under the conditions of this trial, CBD was unable to interfere with symptoms of crack-cocaine withdrawal. Further studies with larger outpatient samples involving different doses and treatment periods would be desirable and timely to elucidate the potential of CBD to induce reductions in crack-cocaine self-administration.

Estresse percebido e o uso de álcool, tabaco e outras drogas entre universitários / Stress and the use of alcohol, tobacco and other drugs in undergraduates

Avaliar a consumo de drogas em uma população de universitários e verificar as associações com estresse percebido foi o objetivo desta pesquisa. A metodologia utilizada foi de pesquisa descritiva com uma população de 373 universitários. A coleta dos dados se deu de forma online; os participantes responderam ao TCLE, o questionário sociodemográfico, o instrumento para mensurar estresse (escala de Estresse Percebido - EP-10) e consumo abusivo de droga (ASSIST). Para verificar a associação entre o uso abusivo de drogas e a variável estudada foi utilizado o modelo de regressão logística com a significância de p<0,05. A regressão logística revelou associação significativa entre uso de tabaco, ter religião e morar com os pais. Para o consumo de álcool e outras drogas a regressão logística apresentou associação com alto estresse. Concluímos que quanto mais os universitários são expostos a fatores de risco, como estresse, maiores as probabilidades para o consumo de drogas.

Current study analyzes drug consumption in undergraduates and verifies the association with stress. Methodology involves descriptive research in 373 undergraduates. Data were collected online and participants responded to TCLE, sociodemographic questionnaire, stress measuring tool (Perceived Stress Scale ­ EP-10) and illicit drug consumption. Logistic regression at 0.05% significance was employed to assess the association between abuse drugs and the variable under analysis. Logistic regression revealed significant association between tobacco usage, religion and living with parents. In the case of alcohol consumption and other drugs, logistic regression provided association with high stress. The more undergraduates are exposed to risk factors, such as stress, the more their possibilities in drug consumption.

Brazilian cross-cultural adaptation and validation of the List of Threatening Events Questionnaire (LTE-Q)

Objective: To perform a construct validation of the List of Threatening Events Questionnaire (LTE-Q), as well as convergence validation by identifying its association with drug use in a sample of the Brazilian population. Methods: This is a secondary analysis of the Second Brazilian National Alcohol and Drugs Survey (II BNADS), which used a cross-cultural adaptation of the LTE-Q in a probabilistic sample of 4,607 participants aged 14 years and older. Latent class analysis was used to validate the latent trait adversity (which considered the number of events from the list of 12 item in the LTE experienced by the respondent in the previous year) and logistic regression was performed to find its association with binge drinking and cocaine use. Results: The confirmatory factor analysis returned a chi-square of 108.341, weighted root mean square residual (WRMR) of 1.240, confirmatory fit indices (CFI) of 0.970, Tucker-Lewis index (TLI) of 0.962, and root mean square error approximation (RMSEA) score of 1.000. LTE-Q convergence validation showed that the adversity latent trait increased the chances of binge drinking by 1.31 time and doubled the chances of previous year cocaine use (adjusted by sociodemographic variables). Conclusion: The use of the LTE-Q in Brazil should be encouraged in different research fields, including large epidemiological surveys, as it is also appropriate when time and budget are limited. The LTE-Q can be a useful tool in the development of targeted and more efficient prevention strategies.

The Brazilian standardization of the MATRICS consensus cognitive battery (MCCB): Psychometric study.

OBJECTIVE: Translate, adapt, and validate the MATRICS Consensus Cognitive Battery (MCCB) in Brazil. METHOD: The present study followed three steps: 1) translation to Portuguese, cultural adaptation, and back translation to English; 2) completion of a pilot study (N=30) conducted with the purpose of assessing whether the general comprehension of the items was clear and all participants adequately responded to the battery; 3) completion of a Reliability and Validation Study of the Brazilian version of the MCCB with 99 individuals with schizophrenia and 99 healthy subjects. All participants were administered the Structured Clinical Interview for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) and patients were also rated on the Global Assessment of Functioning (GAF) Scale and the Positive and Negative Symptoms Scale (PANSS). RESULTS: The results showed adequate to high levels of baseline and 4-week retest reliability, except the MSCEIT-ME; adequate internal consistency for the MSCEIT-ME for the total sample and patients group, and moderate Alpha for the health control sample; as well as evidence of convergent validity and sensitivity to differentiate performance between the groups. All the 10 MCCB measures showed the lowest learning effects. CONCLUSION: Overall the Brazilian version of the MCCB showed similar results to the original North American version. Our findings provides reassurance that the MCCB is a reliable and valid measure of cognition across different countries and cultures, which is especially important to the ongoing work in attempting to discover cognition-enhancing drugs and the effects of cognitive interventions for the treatment of schizophrenia.

Implicações do uso de álcool, tabaco e outras drogas na vida do universitário / Implications of the use of alcohol, tobacco and other drugs in the university student’s life / Implicaciones del consumo de alcohol, tabaco y otras drogas en la vida del universitario

OBJECTIVE: To assess risk behaviours related to the use of alcohol and other drugs among university students. METHODS: Cross-sectional descriptive study, conducted in 2012 in a town of Alto Paranaíba region, in Minas Gerais State, with a sample of 123 university students, who answered questionnaires containing the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), the Alcohol Use Disorders Identification Test (AUDIT), and the questionnaire on Risk Behaviours Associated with Alcohol and Other Drugs Abuse.

Mothers with depression, school-age children with depression? A systematic review.

PURPOSE: To carry out a systematic review of the association between maternal and school-age children depression and covariate factors. DESIGN AND METHODS: The key words maternal depression, depressed children, and school-age key words were searched in Medline, Lilacs, Scielo, IndexPsi, and PsycInfo (2004-2010). Clinical and community cross-sectional and longitudinal studies were included. A qualitative checklist was used. FINDINGS: Thirty studies were included (21.926 dyads). The results supported the association, showing several modulators: family environment, marital adjustment, social support, depression symptoms, and children-related variables. Limitations were nonrandom samples, single informants, and nondepression diagnosis. PRACTICE IMPLICATIONS: Identifying mothers with depression may be useful for prevention and early detection of school-age children's depression.

Validity of the PHQ-2 for the screening of major depression in Parkinson's disease: two questions and one important answer.

INTRODUCTION: Depression is the most common psychiatric comorbidity in Parkinson's disease (PD), but is often under-diagnosed and under-recognized. OBJECTIVES: To evaluate and compare the psychometric qualities of the Patient Health Questionnaire (PHQ-2) and the depression item of the Unified Parkinson's Disease Rating Scale (UPDRS). METHOD: Cross-sectional study conducted at a movement disorders outpatient clinic. One hundred ten patients with a diagnosis of PD without dementia were evaluated. A neurologist administered the PHQ-2 and the UPDRS, and the diagnosis of major depression was performed using the structured clinical interview for DSM disorders - clinical version. Two self-rating scales (Zung Self-rating Depression Scale and 15-item Geriatric Depression Scale) were also used. RESULTS: The prevalence of current depression in the sample was 25.5% (n = 28). The scores of the PHQ-2 discriminated between subjects with and without depression, with an area under the receiver operating characteristic curve of 0.90. The sensitivity and specificity for a cut-off score of three were 75% and 89%, respectively. The values for the depression item of the UPDRS were slightly lower. CONCLUSION: The PHQ-2 is a valid tool for screening depression in PD.

[Anthropometric and metabolic evaluation of first-degree male relatives of women with polycystic ovary syndrome]. / Avaliação antropométrica e metabólica de parentes de primeiro grau do sexo masculino de mulheres com síndrome do ovário policístico.

PURPOSE: To evaluate clinical and laboratory characteristics of first-degree male relatives of patients with a confirmed diagnosis of polycystic ovary syndrome (PCOS) and to compare the findings with a control group with no family history of PCOS. METHODS: We randomly selected 28 male individuals aged 18 to 65 years who were first-degree relatives of women diagnosed with PCOS and 28 controls matched for age, waist and body mass index (BMI). RESULTS: Men with 1st degree kinship with women with PCOS had higher levels of triglycerides (189.6±103.1 versus 99.4±37.1, p<0.0001), Homeostasis Model Assessment (HOMA-IR) (3.5±9.1 versus 1.0±1.0, p=0.0077) and glucose (130.1±81.7 versus 89.5±7.8, p=0.005), and lower levels of sex hormone binding globulin (SHBG) (23.8±13.8 versus 31.1±9.1, p=0.003). SHBG levels correlated independently with triglyceride levels. These individuals also had more clinical signs of hyperandrogenism. CONCLUSIONS: Male individuals who are first-degree relatives of patients with PCOS have a higher degree of dyslipidemia and insulin resistance, lower levels of SHBG, and more evident clinical signs of hyperandrogenism. These findings suggest that insulin resistance may be of hereditary origin in individuals with a family history of PCOS regardless of anthropometric parameters.

Facial affect processing in social anxiety: tasks and stimuli.

Social anxiety (SA) has as its main feature the fear of social situations, being characterized as social phobia or social anxiety disorder when functional impairment emerges as a result of that fear. Although the recognition of the condition has increased in recent years, it is believed that many patients and physicians still take the symptoms of the disorder for personality traits with no need for treatment. There is evidence that people with SA display abnormal patterns of facial emotion processing that could account for the onset and maintenance of the disorder. The objective of this review is to describe, compare, and discuss the methods used to study facial emotion processing in SA with an emphasis on the tasks and stimuli employed. Articles were searched for on online scientific databases. Forty research articles were selected according to the inclusion and exclusion criteria established. The articles were read and information from them was gathered on a comparative table for analysis. Evidence available to date suggests that SA individuals have abnormal patterns of facial information processing characterized by a bias for negative emotions. The results of the articles analyzed have a high degree of concordance, in spite of the variety of tasks and stimuli employed. The similarity between results from non-clinical samples with SA and patients affected by social phobia speaks in favor of the current view that SA occurs as a continuum of severity, rather than a clearly circumscribed nosological entity.

The fast alcohol screening test (FAST) is as good as the AUDIT to screen alcohol use disorders.

This study was aimed at assessing the psychometric qualities of the fast alcohol screening test (FAST), and at comparing these qualities to those of the alcohol use disorders identification test (AUDIT) in three samples of Brazilian adults: (i) subjects attended at an emergency department (530); (ii) patients from a psychosocial care center (40); and (iii) university students (429). The structured clinical interview for diagnosis (SCID)-IV was used as gold standard. The FAST demonstrated high test-retest and interrater reliability coefficients, as well as high predictive and concurrent validity values. The results attest the validity and reliability of the Brazilian version of the FAST for the screening of indicators of alcohol abuse and dependence.

Avaliação antropométrica e metabólica de parentes de primeiro grau do sexo masculino de mulheres com síndrome do ovário policístico / Anthropometric and metabolic evaluation of first-degree male relatives of women with polycystic ovary syndrome

OBJETIVO: avaliar as características clínicas e laboratoriais de parentes de primeiro grau do sexo masculino de pacientes com diagnóstico confirmado de síndrome de ovários policísticos (SOP) e comparar os achados com um grupo controle sem história familiar de SOP. MÉTODOS: foram selecionados aleatoriamente 28 homens com idade entre 18 e 65 anos que possuíam parentesco de primeiro grau com mulheres diagnosticadas com SOP e 28 controles pareados por idade, cintura e índice de massa corporal (IMC). RESULTADOS: homens com parentesco de 1º grau com mulheres com SOP comparados ao Grupo Controle apresentaram níveis mais elevados de triglicerídeos (189,6±103,1 versus 99,4±37,1; p<0,0001), HOMA-IR (Homeostase Model Assesment) (3,5±9,1 versus 1,0±1,0; p=0,0077) e glicemia (130,1±81,7 versus 89,5±7,8; p=0,005), além de menores níveis da globulina ligadora de hormônios sexuais (SHBG) (23,8±13,8 versus 31,1±9,1; p=0,003). Os níveis de SHBG se correlacionaram independentemente com os níveis de triglicérides. Os parentes de 1º grau também apresentavam mais sinais clínicos de hiperandrogenismo. CONCLUSÕES: parentes de primeiro grau do sexo masculino das pacientes com SOP apresentam maior grau de dislipidemia e de resistência à insulina, além de níveis mais baixos de SHBG com mais sinais clínicos de hiperandrogenismo. Esses achados sugerem que a resistência à insulina pode ter origem hereditária em indivíduos com história familiar de SOP, independentemente de parâmetros antropométricos.

Is the full version of the AUDIT really necessary? Study of the validity and internal construct of its abbreviated versions.

BACKGROUND: This study was aimed at assessing the psychometric qualities of the abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT-3, AUDIT-4, AUDIT-C, AUDIT-PC, AUDIT-QF, FAST, and Five-Shot) and at comparing them to the 10-item AUDIT and the CAGE in 2 samples of Brazilian adults. METHODS: The validity and internal consistency of the scales were assessed in a sample of 530 subjects attended at an emergency department and at a Psychosocial Care Center for Alcohol and Drugs. The Structured Clinical Interview for DSM-IV was used as the diagnostic comparative measure for the predictive validity assessment. The concurrent validity between the scales was analyzed by means of Pearson's correlation coefficient. RESULTS: The assessment of the predictive validity of the abbreviated versions showed high sensitivity (of 0.78 to 0.96) and specificity (of 0.74 to 0.94) indices, with areas under the curve as elevated as those of the AUDIT (0.89 and 0.92 to screen for abuse and 0.93 and 0.95 in the screening of dependence). The CAGE presented lower indices: 0.81 for abuse and 0.87 for dependence. The analysis of the internal consistency of the AUDIT and its versions exhibited Cronbach's alpha coefficients between 0.83 and 0.94, while the coefficient for the CAGE was 0.78. Significant correlations were found between the 10-item AUDIT and its versions, ranging from 0.91 to 0.99. Again, the results for the CAGE were satisfactory (0.77), although inferior to the other instruments. CONCLUSIONS: The results obtained in this study confirm the validity of the abbreviated versions of the AUDIT for the screening of alcohol use disorders and show that their psychometric properties are as satisfactory as those of the 10-item AUDIT and the CAGE.

Psychometric qualities of the Brazilian versions of the Fagerström Test for Nicotine Dependence and the Heaviness of Smoking Index.

INTRODUCTION: This study examined the psychometric properties of the Brazilian versions of the Fagerström Test for Nicotine Dependence (FTND) and the Heaviness of Smoking Index (HSI). METHODS: The test-retest reliability of the FTND was assessed in a sample of 61 smoking university students, with a 15-day interval between assessments. The interrater reliability was examined in 30 smoking patients of a psychosocial care center for alcohol and drug users (PCC-AD). The reliability coefficient was estimated by the kappa and intraclass correlation coefficients. The predictive validity, internal consistency, and factor structure of the FTND and the HSI were evaluated by factor analysis in 271 smokers treated at an emergency unit and at the PCC-AD. The gold standard was the nicotine dependence criteria of DSM-IV, as assessed by the Structured Clinical Interview for DSM-IV. RESULTS: The FTND showed high reliability, with correlation coefficients of .92 for test-retest reliability and .99 for interrater reliability. Both the FTND and the HSI presented high levels of sensitivity and specificity. The internal consistency evaluation yielded a Cronbach's alpha coefficient of .83 for the FTND and of .56 for the HSI. An exploratory factor analysis found 2 factors in the FTND, which were validated by a confirmatory factor analysis. DISCUSSION: The results obtained in this study confirm the validity and reliability of the Brazilian versions of the FTND and the HSI.

Alcohol Use Disorders Identification Test (AUDIT): an updated systematic review of psychometric properties

The Alcohol Use Disorders Identification Test (AUDIT) is an instrument used to screen for alcohol-related problems. It has been increasingly used in many different countries in both the original English-language version and its many translated versions. Because of the need for screening instruments of faster administration, shortened versions of the AUDIT have also been developed. This study was aimed at expanding the work by Berner and colleagues (2007) in an attempt to answer some remaining questions as well as to identify and evaluate studies on the validation of modified versions of the AUDIT, which have not been previously analyzed. In order to do so, we identified indexed articles published between 2002 and 2009 related to the psychometric qualities of the AUDIT by matching the keywords: alcohol, Alcohol Use Disorders Identification Test, and AUDIT. We found 47 articles that evaluated the AUDIT in different countries and in diverse health and community contexts, involving adolescent, adult, and elderly samples. The studies confirmed the validity and efficiency of the AUDIT in the identification of harmful use, abuse, and dependence of alcohol, both in the original version and in modified ones. The possibility of using brief and efficient versions is of great value, since certain health contexts demand faster assessment. The results also showed that the reduced versions have satisfactory psychometric qualities, sometimes with sensitivity values higher than those of the AUDIT itself. The studies analyzed confirm the efficiency of the AUDIT both in its original, reduced, and language-adapted versions in different contexts and cultures.(AU)
