Patterns of Ecstasy Use and Associated Harm: Results of a Brazilian Online Survey

The aim of this study was to gather information about ecstasy users in Brazil, particularly on issues related to risks associated to the use of the drug, so as to offer a basis to prevention projects. A total of 1,140 Brazilian ecstasy users answered an online questionnaire from August 2004 to February 2005. Participants were predominantly young single heterosexual well-educated males from upper economical classes. A categorical regression with optimal scaling (CATREG) was performed to identify the risks associated with ecstasy use. ""Pills taken in life"" had a significant correlation with every investigated risk, particularly ecstasy dependence, unsafe sex, and polydrug use. ""Gender,"" ""sexual orientation,"" and ""socioeconomic class"" were not predictive of risk behavior. The Internet proved to be a useful tool for data collection. Given the recent increase in ecstasy availability in Brazil, a first prevention campaign directed toward the drug is urgent. At least in a preliminary Brazilian intervention, the campaign must be conducted at night leisure places, mainly frequented by youngsters from upper socioeconomic classes. The results do not call for information material with specific targets, such as gender or sexual orientation. The study`s limitations have been noted.

LIRAGLUTIDE: NEW RESULTS IN THE TREATMENT OF TYPE 2 DIABETES MELLITUS

New drugs for type 2 diabetes that act on incretin metabolism have been shown to improve glycemic control, reduce body weight and have a low risk for hypoglycemia. Among these, liraglutide is the first glucagon-like peptide 1 (GLP-1) analogue approved for subcutaneous, once-daily administration. According to results from clinical trials, liraglutide is on attractive alternative for the early treatment of type 2 diabetes. The results of the LEAD (Liraglutide Effect and Action in Diabetes) study program demonstrated the efficacy and safety of liraglutide in terms of reduction of glycated hemoglobin (HbA(tc)) levels, significant loss of body weight that was maintained over the long term, better control of the lipid profile and systolic arterial pressure, reduction of the risk for hypoglycemia and reduction of cardiovascular risk. Moreover, the drug was demonstrated to be safe and can be co-administered with oral antidiabetic agents. The product's tolerability has been demonstrated, with nausea as the most common adverse event, which waned from the fourth week of treatment.

Concurrent crack and powder cocaine users from Sao Paulo: Do they represent a different group?

Abstract Background Cocaine abuse is a serious and socially damaging illegal drug problem. Different routes of administration are associated with a specific progression of use, different degrees of abuse liability, propensity for dependence and treatment response. There have been relatively few studies comparing different cocaine users groups and no studies into the characterization of the group of individuals reporting concurrent use of powder cocaine and crack cocaine. Methods Six hundred and ninety-nine cocaine users were assessed during the period August 1997 to October 1998 in one outpatient and six inpatient clinics located in the São Paulo, Brazil. Patients were interviewed using a structured questionnaire schedule in Portuguese, designed specifically for the Brazilian population. The statistical analyses were performed using either ANOVA or a chi-squared test and focusing on their preferred form of use/route of administration and other variables. Results For 83% of the variables tested in this study, the Dual Users subgroup (using both powder and crack cocaine) demonstrated statistical differences from the single drug user subgroups. Those differences include the initiation of cocaine, the abuse of other illicit drugs, and rates of criminal history. Conclusion These data suggest cocaine-dependent individuals who report use of both powder and crack cocaine are an at least partially, distinct subgroup. However, further studies will be necessary to confirm this and to determine if they also show a different treatment response.

Influence of psychosocial risk factors on the trajectory of mental health problems from childhood to adolescence: a longitudinal study

Background Longitudinal epidemiological studies involving child/adolescent mental health problems are scarce in developing countries, particularly in regions characterized by adverse living conditions. We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP) over time. Methods A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002–2003 (Time 1/T1) to 2007–2008 (Time 2/T2), with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%). Outcome: CAMHP at T2 according to the Child Behavior Checklist/CBCL’s total problem scale. Psychosocial factors: T1 variables (child/adolescent’s age, family socioeconomic status); trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression); and T2 variables (maternal education, child/adolescent’s social support and pro-social activities). Results Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression. Conclusions The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

A COCAÍNA E O CRACK: As Drogas da Morte

Diante da relevância mundial do desafio no enfrentamento do tema concernente ao uso de drogas, o presente artigo tem por escopo principal abordar alguns aspectos sobre a cocaína em suas diversas formas de consumo, isto é, como chá, em pó (inalada), como injeção (diluída) e fumo – neste caso denominado crack (“pedra”) ou merla (“pasta”). Nesse contexto, no primeiro tópico, explana-se um breve histórico sobre as drogas, com enfoque nas espécies do tipo estimulantes, no qual se ressalta os efeitos tóxicos que causam ao organismo dos usuários. A seguir, há relevo sobre os problemas sociais e psicológicos acarretados pelo uso da cocaína em qualquer de suas formas, bem como expõe apontamentos sobre métodos de tratamento

Use of alcohol and other drugs among Brazilian college students: effects of gender and age

Objective: To assess the frequency of drug use among Brazilian college students and its relationship to gender and age. Methods: A nationwide sample of 12,721 college students completed a questionnaire concerning the use of drugs and other behaviors. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-WHO) criteria were used to assess were used to assess hazardous drug use. A multivariate logistic regression model tested the associations of ASSIST-WHO scores with gender and age. The same analyses were carried out to measure drug use in the last 30 days. Results: After controlling for other sociodemographic, academic and administrative variables, men were found to be more likely to use and engage in the hazardous use of anabolic androgenic steroids than women across all age ranges. Conversely, women older than 34 years of age were more likely to use and engage in the hazardous use of amphetamines. Conclusions: These findings are consistent with results that have been reported for the general Brazilian population. Therefore, these findings should be taken into consideration when developing strategies at the prevention of drug use and the early identification of drug abuse among college students.
