    ABSTRACT: Depression is a serious condition that is associated with great psychic suffering and major impairments on the patient’s general health, quality of life, and social and occupational activities. In some cases, it may lead to suicide. Regardless of the innumerous research works that have already addressed depression in wide and specific facets, there is still a lot to grasp in order to effectively help preventing and treating depression. This work presents data from a randomized clinical trial that sought to evaluate the effectiveness of two brief psychotherapeutic for Depression: Cognitive Behavioral Therapy (CBT) and Supportive-Expressive Dynamic Psychotherapy (SEDP). This was a convenience sample composed of 46 individuals that were evaluated using a structured diagnostic interview and then randomly allocated to the SEDP group. We examined baseline and post-intervention serum levels of the Interleukin-6 (IL-6) and the Tumor Necrosis Factor (TNF-α) in addition to the severity of depressive symptoms according to the Outcome Questionnaire - 45.2 (OQ-45.2) and the Beck Depression Inventory (BDI). Results show that serum IL-6 and TNF-α levels, as well as the scores from the OQ-45.2 and the BDI significantly decreased after 16 sessions of SEDP (p<0.001), except for the Interpersonal Relationship domain from the OQ-45. Despite the reduction of serum cytokines levels and OQ-45 and BDI scores, they were only significantly correlated regarding the social role domain from the OQ-45. Nonetheless, our data suggests an effective role of brief psychodynamic psychotherapy in the reduction of depressive symptoms and serum inflammatory levels that are associated with depression.

    ABSTRACT: The aim of this study was to determine the differences in personality traits between individuals with Major Depressive Disorder (MDD) and Bipolar Disorder (BD) during a depressive episode, when it can be hard to differentiate them. Data on personality traits (NEO-FFI), mental disorders (Mini International Neuropsychiatric Interview Plus) and socioeconomic variables were collected from 245 respondents who were in a depressive episode. Individuals with MDD (183) and BD (62) diagnosis were compared concerning personality traits, clinical aspects and socioeconomic variables through bivariate analyses (chi-square and ANOVA) and multivariate analysis (logistic regression). There were no differences in the prevalence of the disorders between socioeconomic and clinical variables. As for the personality traits, only the difference in Agreeableness was statistically significant. Considering the control of suicide risk, gender and anxiety comorbidity in the multivariate analysis, the only variable that remained associated was Agreeableness, with an increase in MDD cases. The brief version of the NEO inventories (NEO-FFI) does not allow for the analysis of personality facets. During a depressive episode, high levels of Agreeableness can indicate that MDD is a more likely diagnosis than BD. Retrieved from http://www.psy-journal.com/article/S0165-1781(15)30869-6/abstract

    ABSTRACT: Background: It has been shown that maternal mental health is associated with poorer skills development in the offspring. However, the evidence evaluating the association between social anxiety disorder (SAD) and cognitive or language development, is scarce. Aim: To evaluate the association between maternal SAD and performance in cognitive and language tests in 30-month old children. Study design: This was a cohort study involving young women evaluated since pregnancy. Subjects: We evaluated 520 mother-child dyads who received prenatal medical assistance through the National Public Health System in a southern Brazilian city, from October 2009 to March 2011. Outcome measures: We used the Mini Neuropsychiatric Interview Plus (MINI Plus) to assess SAD among young mothers. Cognitive and language performance in their offspring was analyzed using the Bayley Scales of Infant and Toddler Development - 3rd Edition. Results: We found an association between maternal SAD and performance in cognitive and language tests. Children of mothers with SAD had in average 4.5 less points in the Bayley scale, when compared to those with mothers without SAD: in the cognitive (β=-4.53 [95% CI -7.8; -1.1] p=0.008) and language subscales (β=-4.54 [95% CI -9.0; -0.5] p=0.047). Conclusions: Our findings suggest that children with mothers suffering from SAD have poorer cognitive abilities and language skills.

    ABSTRACT: Background: Cocaine abuse is capable of activating the innate immune system in the CNS resulting in deregulation of homeostasis between pro and antiinflammatory cytokines. The aim of this study was to investigate serum levels of pro and antiinflammatory cytokines, IL-6 and IL-10 respectively, in cocaine users from a young population-based sample. Methods: This is a case-control study nested in a cross-sectional population-based survey, with individuals of 18 and 35 years old. Two groups were selected: 24 healthy controls and 12 subjects who reported cocaine use. Serum IL-6 and IL-10 were measured by ELISA using a commercial kit. Results: There was a statistically significant increase in IL-6 (p=0.037) and decrease in IL-10 (p=0.007) serum levels, between cocaine users and the control group. There was also an increase in the ratio IL-6/IL-10 (p=0.013) among cocaine users individuals, when compared to the control group. Conclusions: Our results suggest that cocaine users showed an activation of the immune system when compared a control group, demonstrating a disruption in the balance of pro and antiinflammatory cytokines. Thus, peripheral cytokines may represent a putative biomarkers for cocaine users, contributing to the development of diagnosis and effective treatments.

    ABSTRACT: This article aims to assess the prevalence of fatherhood in adolescence (FA) and associated factors in a community sample of 14 to 35 year-old men. Cross-sectional population-based study realized in the urban area of the city of Pelotas-RS, Brazil. The sample was selected by clusters, according to the city census. This sub-study only comprised sexually active men. Data were collected using a self-administered questionnaire in the participants’ homes. The sample was composed for 934 men. The prevalence of fatherhood in adolescence was 8% (n = 75). We verified higher prevalence of FA among those that reported paternal absence (p < 0.001), those that had lived with stepfather (p = 0.044), and among those that had sexual debut before the age of 14 (p = 0.011). Paternal absence, have lived with a stepfather, and early sexual experience are associated factors to fatherhood in adolescence. © 2015 Associacao Brasileira de Pos - Graduacao em Saude Coletiva.

    ABSTRACT: The objective was to evaluate the effect of psychoeducation on biological rhythm and in the reduction of depressive, anxious, and manic symptoms at 12 months' follow-up. This was a randomized clinical trial with young adults aged 18 to 29 years, diagnosed with bipolar disorder. Biological rhythm was assessed with the Biological Rhythm Interview Assessment in Neuropsychiatry (BRIAN). Participants were randomized for combined intervention (psychoeducation plus medication) or treatment-as-usual (medication alone). The sample consisted of 61 patients (29 TAU; 32 combined intervention). Although it failed to separate by a marginal difference, the combined intervention seems to be more effective than TAU in relation to improvement of depressive symptoms at post-intervention (p = 0.074) and regulation of sleep/social domain at 6 months' follow-up (p = 0.057). Improvement of depressive symptoms as well as regulation of sleep and social activities are known to prevent episode onset and thus improve long-term outcomes.

    ABSTRACT: To assess the functional impairment of young adults with bipolar disorder with substance abuse/dependence comorbidity. Cross-sectional study within a community sample. Bipolar Disorder was assessed by qualified psychologists using The Mini International Neuropsychiatric Interview - PLUS (MINI-PLUS). Substance abuse and dependence was assessed using the "Alcohol, Smoking and Substance Involvement Screening Test" (ASSIST). Functional impairment was assessed using the Functional Assessment Short Test (FAST). The sample included 1259 young adults. The prevalence of Bipolar Disorder (BD) without Substance Abuse/Dependence (SAD) comorbidity was 5.9% (n=74), and the prevalence of bipolar disorder with substance abuse/dependence comorbidity was 1.4% (n=17). Both groups showed higher impairment in overall functioning, interpersonal relationship, and leisure time as compared to controls. In addition, BD+SAD showed higher impairment in the cognitive functioning domain of FAST. A battery of neuropsychological tests was not performed. Functional impairment is associated with BD, independently of substance abuse or dependence. In addition, BD+SAD present a more severe impairment in the cognitive domain of FAST as compared to controls. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: To evaluate the effect of cognitive therapy on biological rhythm and depressive and anxious symptoms in a twelve-month follow-up period. In addition, correlations between the reduction of depression and anxiety symptoms and the regulation of biological rhythm were observed. This was a randomized clinical trial with young adults from 18 to 29 years of age who were diagnosed with depression. Two models of psychotherapy were used: Cognitive Behavioral Therapy (CBT) and Narrative Cognitive Therapy (NCT). Biological rhythm was assessed with the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN). Severity of depressive and anxious symptoms was assessed by the Hamilton Depression Rating Scale (HDRS) and the Hamilton Anxiety Rating Scale (HARS), respectively. The sample included 97 patients who were divided within the protocols of psychotherapy. There was a significant reduction in depressive and anxious symptoms (p<0.001) and an increase on regulation of biological rhythm (p<0.05) at the twelve-month follow-up. Moreover, we showed a positive correlation between the reduction of depressive symptoms and regulation of biological rhythm (r=0.638; p<0.001) and between the reduction of anxious symptoms and regulation of biological rhythm (r=0.438; p<0.001). Both models showed that cognitive therapy was effective on the reduction of depressive and anxious symptoms and on the regulation of biological rhythm at a twelve-month follow-up evaluation. This study highlights the association between biological rhythm and symptoms of depression and anxiety. We did not assess genetic, hormonal or neurochemical factors and we did not include patients under pharmaceutical treatment or those with severe symptomatology. Copyright © 2015 Elsevier B.V.

    ABSTRACT: Studies have already pointed out the contribution of oxidative stress in the pathophysiology of major depressive disorder (MDD). The aim of the present study was to investigate the oxidative-antioxidative systems in MDD and in response to cognitive psychotherapies. Oxidative stress were analyzed in 49 MDD patients at baseline, post-treatment, and follow-up; and 49 control subjects without history of psychiatric disorders. MDD subjects presented an increase in oxidative damage related to control subjects for thiobarbituric acid reactive species (TBARS), nitric oxide, and a decrease in total thiol content. Cognitive psychotherapies were able to counteract peripheral oxidative stress in MDD patients, reducing TBARS levels (p<0.001) in the follow-up, nitric oxide (p<0.001) in the post-treatment and follow-up, and increasing the total thiol content (p<0.01) in the post-treatment and follow-up. Oxidative stress was associated with MDD and the regulation of these parameters might represent an important mechanism associated with the clinical improvement of cognitive psychotherapy.

    ABSTRACT: To assess biological rhythm disruptions among drug-naïve young adults with bipolar disorder (BD), major depressive disorder (MDD), and community controls. This was a cross-sectional study nested in a population-based study. BD and MDD were diagnosed using the Structured Clinical Interview for DSM-IV. Biological rhythm disruptions were assessed using the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN). Two hundred seventeen subjects were assessed (49 BD, 74 MDD, and 94 community controls). Biological rhythm disruption was higher in subjects with BD (40.32±9.92; p<0.001) and MDD (36.23±8.71; p<0.001) than community controls (27.67±6.88). Subjects with BD had a higher BRIAN total score (p=0.028) and higher disruption in sleep/social domains (p=0.018) as compared to MDD. In addition, the BRIAN scores were higher in current MDD, euthymic BD, and BD in current episode group, as compared to community controls. Cross-sectional design. Absence of assessment of biomarkers of biological rhythms. Bipolar disorder and major depressive disorder are associated with disruption in biological rhythm. In addition, disruption in sleep/social rhythms is higher in subjects with BD when compared to subjects with MDD. We also verified biological rhythm disruption in subjects with BD during euthymic status, but not in remitted MDD. Regulation of biological rhythm may be a means to identify patients with mood disorders and potentially differentiate MDD from BD. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: To verify the relationship between behavioral dysphonia and current depressive episodes in municipal elementary school teachers. We hypothesize that teachers with behavioral dysphonia will be more susceptible to psychiatric disorders. Cross-sectional study, quantitative, conducted across municipal schools in both rural and urban regions of Pelotas. Five-hundred seventy-five teachers from urban and rural areas of the same Brazilian state were included. The full version of the Voice Handicap Index validated into Brazilian Portuguese was used to determine the presence of behavioral dysphonia. A profile of vocal behaviors was also used to quantify the number of phonotraumatic events. In addition, the Mini-International Neuropsychiatric Interview was used to determine current episodes of depression. Data were analyzed via correlative studies using chi-square and Poisson regression analyses. Across all teachers, the prevalence of dysphonia was 33.9% and 55% reported that they had already taken a leave because of their voice. Those teachers with a current depressive episode had a higher rate of dysphonia compared with those without depression (prevalence ratio [PR] 1.66; P < 0.000). Teachers who presented with a risk of serious vocal problems had a prevalence ratio of 2.58, indicating a greater proportion of dysphonia, whereas teachers classified as champions of abuse were five times more likely compared with those teachers with behaved or candidates for voice problems. There is an association between behavioral dysphonia and current depressive episodes in elementary school teachers. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc.

    ABSTRACT: Major depressive disorder (MDD) is a debilitating disorder and its pathophysiology is associated with deregulation of the immune system. We investigated the changes in circulating levels of proinflammatory cytokines (specifically IL-6 and TNF-α) measured by the ELISA kit in two psychotherapeutic interventions for MDD: Narrative Cognitive Therapy (NCT) and Cognitive Behavioral Therapy (CBT). This is a randomized clinical trial including 97 individuals (18 to 29years-old) with MDD. In CBT there was a significant difference in serum levels of IL-6 and TNF-α, therefore indicating that CBT was more effective than NCT on serum levels proinflammatory cytokines.

    ABSTRACT: Nerve growth factor (NGF) is an important member of the neurotrophins group and their involvement in the pathophysiology of major depression disorder (MDD) and suicide risk (SR) has been recently suggested. The aim of this study is to evaluate the changes in NGF serum levels in individuals with MDD and with or without risk of suicide, in subjects from a young population-based sample. This is a paired cross-sectional study nested in a population-based study. Individuals were rated for MDD and SR by a diagnostic interview - Mini International Neuropsychiatric Interview (M.I.N.I). The total population of the sample was comprised of 141 subjects distributed in three groups: 47 healthy controls, 47 subjects with current depressive episode without SR (MDD) and 47 subjects with current depressive episode and with SR (MDD+SR). NGF serum levels were significantly reduced in the MDD and MDD+SR groups when compared with controls (p≤0.001). However, there were no differences in NGF levels between the MDD and MDD+SR groups (p=1.000). These results suggest that reduced NGF serum levels can be a possible biomarker of MDD. Copyright © 2015.

    ABSTRACT: This cross-sectional study evaluated the quality of life and its associated factors among people living with HIV/AIDS at a regional reference center for the treatment of HIV/AIDS in southern Brazil. WHOQOL-HIV Bref, ASSIST 2.0, HAD Scale, and a questionnaire were used to assess 625 participants on quality of life, clinical and sociodemographic characteristics, drug use, depression and anxiety. Multivariate analysis was performed through linear regression. The lowest results for quality of life were associated with being female, age (< 47 years), low education levels, low socioeconomic class, unemployment, not having a stable relationship, signs of anxiety and depression, abuse or addiction of psychoactive substances, lack of perceived social support, never taking antiretroviral medication, lipodystrophy, comorbidities, HIV related hospitalizations and a CD4+ cell count less than 350. Psychosocial factors should be included in the physical and clinical evaluation given their strong association with quality of life domains.

    ABSTRACT: Depression during pregnancy in adolescents is increasing significantly. However, instruments for early depression screening during prenatal care are scarce. Faced this fact, the objective of this research is to identify the best cutoff points for the Edinburgh Postnatal Depression Scale (EPDS) and Beck Depression Inventory (BDI) in a sample of pregnant adolescents. 807 pregnant adolescents, with a mean age of 17 years, met in public antenatal services were evaluated. Two screening scales for depression were analyzed, EPDS and the BDI. These scales had their accuracy measured by AUC of their ROC curve, as well as their respective sensitivity and specificity. In the analysis, the best cutoff for the EPDS was≥10, in which the sensitivity was 81.1% and specificity 82.7%. For the BDI, it was with recognized the cutoff ≥11, sensitivity 86.7% and specificity 73.8%. In the analysis of the ROC AUC, values of 0.89 (CI 0.87-0.92) for the EPDS and BDI for 0.87 (CI 0.84-0.89) were identified compared to the MINI. The sample was composed majority by middle and low income adolescent and the study was performed only with pregnant women in the second trimester. The results indicate that both scales have good accuracy in screening of depression in adolescent mothers. However, the EPDS scale shows higher AUC ROC and also better sensitivity and specificity values, the latter being more precise and effective for screening for depression in this population.

    ABSTRACT: objectives: To verify the prevalence of current posttraumatic stress disorder (PTSD) in young adults, the occurrence of comorbidities and its association with quality of life. Methods: This is a cross-sectional population-based study. The targeted population consisted on indivi duals aged 18 to 24 years old, who lived in the urban area of Pelotas-RS, Brazil. Cluster sampling was applied. PTSD and its comorbidities were assessed using the Mini International Neuropsychiatric Interview (MINI 5.0), whereas quality of life was evaluated with the eight domains of the Medical Outcomes Survey Short-form General Health Survey (SF-36). results: A total of 1,762 young adults were selected. The prevalence of PTSD was 2.1% and current episode of depression was the most prevalent comorbidity (71.9%). The individuals with PTSD had lower scores in all domains of quality of life. conclusion: These findings indicate that PTSD is associated with other psychopathologies, especially depression, and it has a substantial impact over quality of life in a sample of young adults.

    ABSTRACT: This research aims to evaluate factors associated with the presence of comorbidities between mood and anxiety disorders in young adults aged 18 to 24 years, from Pelotas, Rio Grande do Sul State, Brazil. This was a cross-sectional, population-based study with a probabilistic sample by conglomerates. The Mini International Neuropsychiatric Interview (MINI) was used to assess mood and anxiety disorders. The prevalence of mental disorders in the sample (n = 1,561) was of 26.8% of which 9.7% had comorbidities between mood and anxiety disorders. The prevalence of comorbidities on mood and anxiety disorders is almost three times higher among women than men (p < 0.001). Lower education levels, socioeconomic status (p < 0.001) and a history of divorced parents (p < 0.050) was associated with comorbidities between mood and anxiety disorders. The main conclusion is that social factors are highly associated with comorbidities between mood and anxiety disorders. Prevention strategies on mental health should focus particularly on women in vulnerable social conditions.

    ABSTRACT: There are scarce follow-up studies evaluating the role of psychoeducation in the treatment of bipolar disorder, especially in a young sample, with a recent diagnosis and that probably received a few previous interventions. This was a randomized clinical trial with young adults aged 18-29 years, who had been diagnosed with bipolar disorder through the Structured Clinical Interview for DSM (SCID). The evaluation of quality of life was carried out using the Medical Outcomes Survey 36-Item Short-Form Health Survey (MOS SF-36). All participants were randomized into two groups: combined intervention (psychoeducation plus medication) and treatment-as-usual (medication). The sample consisted of 61 patients divided in two groups (29 usual treatment; 32 combined intervention). The quality of life domains did not reveal statistically significant differences when comparing baseline, post-intervention and 6-month follow-up evaluations, which indicates that there is no difference between combined intervention and usual intervention regarding quality of life improvement. Both groups presented improvements in quality of life domains, except General Health and Bodily Pain, at post-intervention. Moreover, this improvement persisted at 6-month follow-up, except for the Role Physical Health domain, which remained reduced. Combined Psychoeducation plus pharmacological intervention is so effective in improving quality of life perception as it is pharmacological only intervention.
