ABSTRACT Objectives High rates of comorbidity between social anxiety disorder (SAD) and alcohol use disorders have been reported, but the predictors of this comorbidity are poorly known and most studies involve primary SAD samples. The aims were to estimate the prevalence and severity of SAD symptoms among alcohol-dependent patients and to investigate sociodemographic and clinical factors associated with SAD comorbidity, including suicidal behaviors. Methods A cross-sectional study with 53 adults who were in treatment for alcohol dependence at a Brazilian public university outpatient service. Assessment instruments Social Phobia Inventory (SPIN), Short Alcohol Dependence Data and Beck Depression Inventory. Bivariate analyses between the categorical outcome (Probable SAD: SPIN ≥ 19) and explanatory variables were conducted. Correlates of SPIN total and subscales scores (dimensional outcomes) were also investigated. Results The diagnosis and treatment of alcohol dependence occurred, on average, 30 years after the onset of alcohol use and 39.6% of the 53 patients (37 men and 16 women) reported alleviation of social anxiety symptoms with alcohol use. Twenty-four (45.3%) patients presented probable SAD. These patients differed from non-SAD alcohol-dependent individuals by having lower income and higher frequency of depression, suicidal ideation, suicide plans and attempts. The SPIN subscales mostly associated with suicidal behaviors were social inadequacy and social inferiority. Conclusions SAD symptoms are common among help-seeking alcohol-dependent individuals and should be directly investigated and treated, since depression and suicidality are associated with this comorbidity. Prospective studies are needed to assess the impact of SAD treatment on the clinical course of alcohol dependence.

Introduction: An increasing number of octogenarian patients is undergoing coronary artery bypass graft surgery (CABG). The short-term results of this procedure have been broadly studied, but there are few national reports on long-term outcomes., Objectives: To describe hospital mortality and long-term survival of patients aged > 80 years undergoing isolated CABG., Methods: Retrospective cohort study with 142 consecutive patients aged > 80 years undergoing isolated CABG in the period between January/1996 and December/2007 in a Brazilian reference center. Mean age (± SD) was 82.3 ± 2.1 years, and 56.3% were male. The prevalence of hypertension was 73.2%, of previous myocardial infarction 30.3%, of diabetes 26.8%, and of renal dysfunction (creatinine ³ 2.0 mg/ml) was 4.9%. The median follow-up was 4.0 years, with a loss of 11.6% of patients. Survival analysis was performed by the Kaplan-Meier method., Results: Overall hospital mortality was 14.8% (95% CI: 8.8 to 20.8), with a reduction of this rate during the study period (1996-1999: 25.9%, 2000-2003: 15.8%, and 2004-2007: 8.6%). Mean survival was 6.5 years (95% CI: 5.5 to 7.5), and the survival rate at 1, 3 and 5 years was 79.4, 73.4 and 65.2%, respectively., Conclusion: Results are in agreement with international reports. Mean survival was 6.5 years and the survival rate at 5 years was 65.2%.
