OBJECTIVE: To analyze the predictors of smoking cessation treatment outcomes in a sample with a high rate of medical and psychiatric disorders and addictions.
METHODS: Analysis of predictors of success of a 6-week treatment provided by an addiction care unit (CAPS-AD) to 367 smokers in Brazil from 2007 to 2010. Forty variables were collected at baseline. Success was defined as abstinence from smoking for a period of at least 14 consecutive days, including the last day of treatment. Twenty variables were selected for the logistic regression model.
RESULTS: The only condition correlated with successful treatment after logistic regression was smoking one's first cigarette 5 minutes or more after waking (beta = 1.85, 95% confidence interval [95%CI] = 1.11-3.10, p = 0.018). Subjects with hypertension and alcohol use disorders and those who were undergoing psychiatric treatment showed success rates comparable to or greater than the average success rate of the sample (34.2-44.4%).
CONCLUSIONS: These findings support the importance of the variable time to first cigarette in treatment outcomes for a sample with a high rate of clinical and psychiatric disorders. Good success rates were observed for pharmacological treatment, which was combined with group therapy based on cognitive-behavioral concepts and integrated into ongoing treatment of other addictions and psychiatric disorders.

Pages: 347 - 352

OBJECTIVE: To assess the prevalence of anxiety disorders and associated factors in young adults.
METHODS: Cross-sectional population-based study of individuals between the ages of 18 and 24 years randomly selected from 89 census-based sectors to ensure an adequate sample size. Household selection within the sectors was performed according to a systematic sampling process. Anxiety disorders were assessed using the Mini International Neuropsychiatric Interview (MINI). The final sample comprised 1,560 young adults.
RESULTS: Of the participants who were diagnosed with anxiety disorders, 12.3% had agoraphobia, 9.7% had generalised anxiety disorder, 4.0% had social phobia, 3.3% had obsessive-compulsive disorder, 2.5% had panic disorder, and 2.1% had post-traumatic stress disorder; only 23.8% had received any previous treatment. Anxiety disorders were associated with sex, socioeconomic status, psychiatric problems in parents, alcohol abuse, and tobacco use.
CONCLUSIONS: The identification of factors associated with anxiety disorders in young people enables us to develop intervention strategies. Anxiety disorders are not only highly prevalent but are also associated with significant functional impairment, significant reductions in quality of life, lower productivity, and higher rates of comorbidities.

Pages: 353 - 359

OBJECTIVE: To compare the neurobehavior of neonates born to adolescent mothers with and without depression during gestation.
METHODS: This prospective cross-sectional study included healthy term neonates born to adolescent mothers with untreated depression during gestation, without exposure to legal or illicit drugs, and compared them with infants born to adolescent mothers without psychiatric disorders. Maternal psychiatric diagnoses were assessed by the Composite International Diagnostic Interview (CIDI 2.1) and neonatal neurobehavior by the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) at 24 to 72 hours of life. Neurobehavioral outcomes were analyzed by ANOVA adjusted for confounders.
RESULTS: 37 infants born to mothers with depression during gestation were compared to 332 infants born to mothers without psychiatric disorders. Infants of mothers with depression had smaller head circumferences. Significant interactions of maternal depression and male gender, gestational age > 40 weeks, regional anesthesia during delivery, vaginal delivery, and infant head circumference > 34 cm were found. Worse performance was noted in the following neonatal neurobehavioral parameters: arousal, excitability, lethargy, hypotonicity, and signs of stress and abstinence.
CONCLUSION: Infants born to adolescent mothers with depression exhibit some behavioral changes in the first days of life. These changes are associated with infant sex, gestational age, type of anesthesia, mode of delivery, and head circumference.

Pages: 360 - 363

OBJECTIVE: To use principal component analysis (PCA) to test the hypothesis that the items of the Hamilton Depression Scale (HAM-D17) have been selected to reflect depression disability, whereas some of the items are specific for sub-typing depression into typical vs. atypical depression.
METHOD: Our previous study using exploratory factor analysis on HAM-D17 has been re-analyzed with PCA and the results have been compared to a dataset from another randomized prospective study.
RESULTS: PCA showed that the first principal component was a general factor covering depression disability with factor loadings very similar to those obtained in the STAR*D study. The second principal component was a bi-directional factor contrasting typical vs. atypical depression symptoms. Varimax rotation gave no new insight into the factor structure of HAM-D17.
CONCLUSION: With scales like the HAM-D17, it is very important to make a proper clinical interpretation of the PCA before attempting any form of exploratory factor analysis. For the HAM-D17, our results indicate that profile scores are needed because the total score of all 17 items in the HAM-D17 does not give sufficient information.

Pages: 364 - 368

OBJECTIVE: This study evaluated the relationship between psychological coping mechanisms and symptoms of anxiety and depression in the preoperative and postoperative periods in relation to the intensity of postoperative pain among patients undergoing breast cancer surgery.
METHODS: Female patients who were scheduled to receive immediate surgical treatment for breast cancer were invited to participate, and answered the following questionnaires: The Hospital Anxiety and Depression Scale (HADS), the Self Report Questionnaire (SRQ-20), the Coping Strategies Questionnaire (CSQ), and the visual analogue scale (VAS).
RESULTS: Of the 139 patients, 122 (87.8%) had an aggressive procedure. Eighty-five patients (61.2%) had a history of preoperative pain while 54 (38.7%) had not. There was no difference in VAS scores between patients subjected to aggressive or non-aggressive surgery. Only the CSQ subscale catastrophizing showed correlation with VAS at 24 hours and with HADS/D postoperatively. The HADS scores indicated both anxiety and depression, but did not distinguish patients subjected to aggressive or non-aggressive surgery.
CONCLUSIONS: The majority of patients did not exhibit depression and anxiety. Coping mechanisms and pain in the preoperative period did not have a strong predictive value for additional postoperative pain, but those with a higher anxiety score had greater pain.

Pages: 369 - 374

OBJECTIVE: To compare adolescents with and without obsessive-compulsive disorder (OCD) with regard to quality of life and to investigate the association between quality of life and clinical characteristics.
METHODS: Participants were recruited from an epidemiological study conducted at high schools in the city of Porto Alegre, southern Brazil. The sample comprised 75 adolescents with OCD and 150 without the disorder, aged between 14 and 18 years. Participants were assessed using the following instruments: Schedule for Affective Disorders and Schizophrenia for School Aged Children - Present and Lifetime Version (K-SADS-PL), Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), World Health Organization Quality of Life Assessment - Abbreviated Version (WHOQOL-BREF), Beck Anxiety Inventory (BAI), and Beck Depressive Inventory II - (BDI-II).
RESULTS: The two groups showed significant differences in relation to depression symptoms, anxiety symptoms, and quality of life (all domains), with a poorer performance among adolescents with OCD when compared to those without the disorder. Stepwise regression analysis revealed a significant association between BDI-II scores and quality of life, in all domains.
CONCLUSIONS: Our findings suggest that adolescents with OCD, especially those with depression symptoms, have a poorer quality of life when compared with adolescents without OCD.

OBJECTIVE: High cardiovascular mortality rates have been reported in patients with bipolar disorder (BD). Studies indicate that matrix metalloproteinases (MMPs) are implicated in cardiovascular diseases. We evaluated the expression pattern of MMP-2 and MMP-9 in blood from patients with BD during acute mania and after euthymia, in comparison with healthy controls.
METHODS: Twenty patients and 20 controls were recruited and matched for sex and age. MMP messenger RNA (mRNA) levels were measured using real-time quantitative polymerase chain reaction (PCR). Body mass index (BMI) was calculated for all subjects.
RESULTS: There were no significant differences in MMP-2 and MMP-9 mRNA expression between patients and controls. mRNA levels were not significantly different during mania and euthymia. However, MMP-2 mRNA levels were negatively associated with BMI in BD patients and positively associated with BMI in controls. There was no difference in the pattern of MMP-9 expression between patients and controls.
CONCLUSIONS: Our results suggest a different pattern of association between MMP-2 and BMI in BD patients as compared with controls. Despite some study limitations, we believe that the role of MMPs in BD should be further investigated to elucidate its relationship with cardiovascular risk.

Pages: 380 - 386

OBJECTIVE: To investigate the effects of cannabidiol (CBD) on mitochondrial complex and creatine kinase (CK) activity in the rat brain using spectrophotometry.
METHOD: Male adult Wistar rats were given intraperitoneal injections of vehicle or CBD (15, 30, or 60 mg/kg) in an acute (single dose) or chronic (once daily for 14 consecutive days) regimen. The activities of mitochondrial complexes and CK were measured in the hippocampus, striatum, and prefrontal cortex.
RESULTS: Both acute and chronic injection of CBD increased the activity of the mitochondrial complexes (I, II, II-III, and IV) and CK in the rat brain.
CONCLUSIONS: Considering that metabolism impairment is certainly involved in the pathophysiology of mood disorders, the modulation of energy metabolism (e.g., by increased mitochondrial complex and CK activity) by CBD could be an important mechanism implicated in the action of CBD.

Pages: 387 - 392

OBJECTIVE: Despite the recognized anti-inflammatory potential of heterocyclic antidepressants, the mechanisms concerning their modulating effects are not completely known. Thus, we evaluated the anti-inflammatory effect of amitriptyline, clomipramine, and maprotiline and the possible modulating properties of these drugs on neutrophil migration and mast cell degranulation.
METHODS: The hind paw edema and air-pouch models of inflammation were used. Male Wistar rats were treated with saline, amitriptyline, clomipramine or maprotiline (10, 30, or 90 mg/kg, per os [p.o.]) 1 h before the injection of carrageenan (300 µg/0.1 mL/paw) or dextran (500 µg/0.1 mL/paw). Then, edema formation was measured hourly. Neutrophil migration to carrageenan (500 µg/pouch) and N-formyl-methionyl-leucyl-phenylalanine (fMLP) (10-6 M/mL/pouch) was also investigated in 6-day-old air-pouch cavities. Compound 48/80-induced mast cell degranulation was assessed in the mesenteric tissues of antidepressant-treated rats.
RESULTS: All tested antidepressants prevented both carrageenan-and dextran-induced edema. The anti-inflammatory effect of these drugs partially depends on the modulation of neutrophil migration, since they significantly counteracted the chemotactic response of both carrageenan and fMLP (p < 0.01). Furthermore, amitriptyline, clomipramine and maprotiline inhibited compound 48/80-induced mast cell degranulation (p < 0.001).
CONCLUSIONS: These results suggest an important anti-inflammatory role of heterocyclic antidepressants, which is dependent on the modulation of neutrophil migration and mast cell stabilization.

Pages: 393 - 405

OBJECTIVE: To review the options for acute and maintenance pharmacological treatment of bipolar disorder in children and adolescents, including the treatment of bipolar depression and comorbid attention deficit/hyperactivity disorder (ADHD).
METHODS: Narrative review of randomized clinical trials and open-label studies published from 2000 to 2012. The PubMed and PsycINFO websites were queried. Case series were included when a higher level of evidence was not available.
RESULTS: Published data from randomized controlled trials (RCTs) in acute mania/hypomania with significant responses are available for lithium, topiramate, risperidone, olanzapine, and aripiprazole. Open trials of lithium and lamotrigine show that these drugs may be effective in the treatment of depressive episodes. No trials of selective serotonin reuptake inhibitors (SSRIs) have been conducted. In the treatment of comorbid ADHD, there are encouraging findings with mixed amphetamine salts and atomoxetine; conflicting results are observed with methylphenidate.
CONCLUSIONS: Published RCTs of traditional mood stabilizers are scarce, but the best available evidence (results from meta-analytic regression) suggests that second-generation antipsychotics (SGAs) as a group are more effective in reducing manic symptoms. Risperidone was the only one included in head-to-head comparisons (vs. lithium and divalproex), showing superiority in terms of efficacy, but with more metabolic side effects, which were also more common in most of the SGAs. There are few studies addressing the treatment of ADHD and depression. Brazilian guidelines for the treatment of pediatric bipolar disorder should also include some SGAs (especially risperidone and aripiprazole) as first-line treatment, and these drugs should be provided by the public health services.

Pages: 406 - 415

OBJECTIVE: To present the most relevant findings regarding the Brazilian Medical Association guidelines for the diagnosis and differential diagnosis of panic disorder.
METHODS: We used the methodology proposed by the Brazilian Medical Association for the Diretrizes Project. The MEDLINE (PubMed), Scopus, Web of Science, and LILACS online databases were queried for articles published from 1980 to 2012. Searchable questions were structured using the PICO format (acronym for "patient" [or population], "intervention" [or exposure], "comparison" [or control], and "outcome").
RESULTS: We present data on clinical manifestations and implications of panic disorder and its association with depression, drug abuse, dependence and anxiety disorders. In addition, discussions were held on the main psychiatric and clinical differential diagnoses.
CONCLUSIONS: The guidelines are proposed to serve as a reference for the general practitioner and specialist to assist in and facilitate the diagnosis of panic disorder.

13 - Psychometric properties of the Beck Depression Inventory-II: a comprehensive review
Yuan-Pang Wang; Clarice Gorenstein
Pages: 416 - 431

OBJECTIVE: To review the psychometric properties of the Beck Depression Inventory-II (BDI-II) as a self-report measure of depression in a variety of settings and populations.
METHODS: Relevant studies of the BDI-II were retrieved through a search of electronic databases, a hand search, and contact with authors. Retained studies (k = 118) were allocated into three groups: non-clinical, psychiatric/institutionalized, and medical samples.
RESULTS: The internal consistency was described as around 0.9 and the retest reliability ranged from 0.73 to 0.96. The correlation between BDI-II and the Beck Depression Inventory (BDI-I) was high and substantial overlap with measures of depression and anxiety was reported. The criterion-based validity showed good sensitivity and specificity for detecting depression in comparison to the adopted gold standard. However, the cutoff score to screen for depression varied according to the type of sample. Factor analysis showed a robust dimension of general depression composed by two constructs: cognitive-affective and somatic-vegetative.
CONCLUSIONS: The BDI-II is a relevant psychometric instrument, showing high reliability, capacity to discriminate between depressed and non-depressed subjects, and improved concurrent, content, and structural validity. Based on available psychometric evidence, the BDI-II can be viewed as a cost-effective questionnaire for measuring the severity of depression, with broad applicability for research and clinical practice worldwide.

Pages: 432 - 434

OBJECTIVE: To investigate whether inpatients with disorganized schizophrenia are more resistant to treatment.
METHOD: Eighty-five inpatients were assessed at admission and at discharge for schizophrenia subtype, symptom severity, and treatment resistance criteria.
RESULTS: Disorganized patients were significantly more treatment-resistant than paranoid patients (60%, p = 0.001), and presented worse scores on the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression Scale (CGI-S), and the Global Assessment of Functioning Scale (GAF) (p < 0.001). Although the difference was not significant, 80% of treatment-resistant patients with disorganized schizophrenia responded to clozapine.
CONCLUSION: Patients with the disorganized subtype of schizophrenia should benefit from clozapine as a second-line agent.

Pages: 435 - 438

OBJECTIVE: To analyze the recognition, identification, and discrimination of facial emotions in a sample of outpatients with bipolar disorder (BD).
METHODS: Forty-four outpatients with diagnosis of BD and 48 matched control subjects were selected. Both groups were assessed with tests for recognition (Emotion Recognition-40 - ER40), identification (Facial Emotion Identification Test - FEIT), and discrimination (Facial Emotion Discrimination Test - FEDT) of facial emotions, as well as a theory of mind (ToM) verbal test (Hinting Task). Differences between groups were analyzed, controlling the influence of mild depressive and manic symptoms.
RESULTS: Patients with BD scored significantly lower than controls on recognition (ER40), identification (FEIT), and discrimination (FEDT) of emotions. Regarding the verbal measure of ToM, a lower score was also observed in patients compared to controls. Patients with mild syndromal depressive symptoms obtained outcomes similar to patients in euthymia. A significant correlation between FEDT scores and global functioning (measured by the Functioning Assessment Short Test, FAST) was found.
CONCLUSIONS: These results suggest that, even in euthymia, patients with BD experience deficits in recognition, identification, and discrimination of facial emotions, with potential functional implications.
