Receiving a diagnosis of depression can have an important impact on the lives of adolescents. However, there is limited information about how youth tackle, attribute meaning to and understand mental health diagnoses. The aim of this study was to explore adolescents' initial reactions after receiving a clinical diagnosis of Major Depressive Disorder in the context of a neurobiological study of depression in Brazil. Using a qualitative design, eight Brazilian adolescents were interviewed twice: immediately after a psychiatric assessment and neuroimaging study, in which they were given a diagnosis of depression, and in a follow-up visit 2 weeks later. Interviews were designed to explore the subjective experience of receiving the diagnosis and the impacts of depression on adolescents' lives. Framework Analysis was used to analyze the accounts. Diagnosis was perceived as a reification of an abnormal status, highlighting the role of stigma and the process of disclosing the diagnosis to others. Adolescents reported the multiple sensemaking processes that occurred when they received a diagnosis of depression, and most struggled with the idea that negative emotions would equate their experience with a disorder. The results show that future efforts could enhance clinical assessment processes with adolescents by exploring adolescents' reactions to diagnosis, as well as the support networks available to them, resulting in increased help-seeking behaviors, and diminished social and personal stigma.

Given the importance that love has in individuals' lives, and considering that more specific studies about the relationship between depression and the way people love are lacking, the aim of the current study was to evaluate the effect of major depressive disorder (MDD) on "love styles." This study was nested in a cohort of adolescent mothers. Women were assessed for MDD at each point of assessment: during pregnancy (T1), at between 30 and 60 postpartum days (T2), and at approximately 30 postpartum months (T3), by using the Mini International Neuropsychiatric Interview (MINI PLUS) tool. The Love Attitudes Scale (LAS) was administered to assess the six love styles at T3. Logistic regression analyses were carried out to express the strength of depression on love styles. We found that chronic major depression had the largest effect on the love styles (low Eros, high Mania, and high Agape), followed by current major depression. However, the same association was not observed in the perinatal period. Thus, the assessment of love style is relevant as it seems that an MDD-related injury in maternal life is related to their attitudes about love and there could be possible harmful consequences of these attitudes to the mother and the whole family.

Major depressive disorder (MDD) seriously threatens human health. BRICS, known as an acronym for "Brazil, Russia, India, China, and South Africa," were also actively carrying out researches on MDD. This study aimed to conduct a bibliometric study of research on MDD conducted by the BRICS. By searching in the Web of Science and using the software Vosviewer and Citespace as analysis tools, this study analyzed the cooperation network at the country, institution, author-specific levels, the research hotspots and trends from BRICS between 2003-2022. A total of 10,911 articles were finally included. Our findings showed that researches on MDD from BRICS rapidly increased during the past two decades. China and India have shown explosive growth, while South Africa has the largest average "Usage Count" and "Time Cited". The current cooperation partners of the BRICS were mainly high-income countries and other developing countries with similar cultures, languages, and geographical locations. Institutions in high-income countries served as the main bridges for BRICS cooperation, while at the author level, some core authors in the BRICS countries serve as centers. China showed a flexible model in domestic partnership, but institutions and authors in the other four countries have gathered to cooperate within the group. BRICS research on MDD mainly focused on cognitive science, brain science, epidemiology, and disease mechanisms. The keywords"gut microbiota", "network analysis," "machine learning" and "sleep quality" showed explosive growth and might become research hotspots in the near future. This bibliometric analysis provided a science knowledge graph and references for other researchers., Competing Interests: Declaration of Competing Interest We confirm that no conflict of interest exists in the submission of this manuscript, and all authors approve the manuscript for publication., (Copyright © 2024.

Aim: To analyze the prospective dose-response relationships between total and domain-specific physical activity (PA) with incident clinical depression., Methods: We used data from two waves (Wave 1: August/2008-December 2010; Wave 2: September/2012-December/2014) of the Brazilian Longitudinal Health Study (ELSA-Brasil) cohort study. Self-reported PA (total, transport, and leisure-time) was the main exposure. Incident clinical depression (new cases of depression between waves) was assessed through the Clinical Interview Schedule-Revised (CIS-R). Poisson regression models, adjusting for potential confounders, were used for data analysis., Results: In 12,709 adults (53.8 % women, mean age: 51.9 ± 9.0), moderate and high volumes of total PA (1-149 min/week: RR = 0.81, 0.58-1.13, 150-299 min/week: RR = 0.55, 95%CI: 0.40-0.76; ≥300 min/week: RR = 0.64, 95%CI: 0.52-0.80), and any volume of leisure-time PA (1-149 min/week: RR = 0.65, 95%CI: 0.50-0.83; 150-299 min/week: RR = 0.67, 95%CI: 0.52-0.88; RR = 0.61, 95%CI: 0.45-0.82) were associated with a lower risk of incident clinical depression. Transport PA protective only in the lower category (0.1-4.4 mMET-h/wk) (RR = 0.71, 95%CI: 0.54-0.94)., Limitations: Other PA domains such as occupational and domestic were not assessed; the use of self-report measures for PA which may be subject to bias and recall issues; lack of assessment of additional potential confounders, such as sedentary behavior and family history of depression., Conclusion: Total and leisure-time PA were associated with lower incidence of clinical depression, even at lower doses. Low, moderate, and high volumes of total and leisure-time PA were associated with lower risk of incident clinical depression. Public health PA interventions aiming to prevent development of clinical depression should consider focusing on leisure-time PA., Competing Interests: Conflict of interest Brendon Stubbs has published a book on exercise and mental illness and is on the Editorial board of Ageing Research Reviews, Mental Health and Physical Activity, The Journal of Evidence Based Medicine and The Brazilian Journal of Psychiatry.

Suicidal ideation represents an important burden worldwide. However, little is known about it in low-/middle-income countries. We investigated this issue in a large cross-sectional of Brazilian civil servants (ELSA-Brasil, the Brazilian Health Longitudinal Study, n =15,105). Logistic univariate and multivariate analyses were performed to evaluate the strength of association (odds ratio, OR) between clinical and sociodemographic variables with acute life-weariness (tiredness of life) and suicidal thoughts. The presence of major depressive disorder (MDD), common mental disorders (CMDs), stressful life-events (SLEs) and poor self-perceived physical health was also collected. MDD and CMDs were strongly associated with suicidal ideation in univariate and multivariate analyses. For life-weariness thoughts, a modest, consistent association was found for female gender, being single, non-White ethnicity and poor education. SLEs and poor self-perceived physical health were also associated with suicidal ideation. Espiritism–Kardecism, but not other religions or Atheism/Agnosticism, was associated with lower rates of life-weariness and suicidal thoughts. To conclude, suicidal ideation does not differ in Brazil compared to developed countries, being primarily associated with psychiatric disorders and, to a lesser but significant extent, to social disadvantage, SLEs, poor self-perceived health and being single.

Background and Objective Major depressive disorder (MDD) has been associated with alterations in the neuroendocrine system and immune function and may be associated with an increased susceptibility to cardiovascular disease, cancer and autoimmune/inflammatory disease. This study was conducted to investigate the relationship between periodontitis and MDD in a convenience sample of hospital outpatients. Material and Methods The sample consisted of 72 physically healthy subjects (36 outpatients with MDD and 36 age-matched controls [± 3 years]). Patients with bipolar disorder, eating disorders and psychotic disorders were excluded. Probing pocket depth and clinical attachment level were recorded at six sites per tooth. Depression was assessed by means of Structured Clinical Interview for DSM-IV. Results Extent of clinical attachment level and probing pocket depth were not different between controls and subjects with depression for the following thresholds: ≥ 3 mm (Mann-Whitney, p = 0.927 and 0.756); ≥ 4 mm (Mann-Whitney, p = 0.656 and 0.373); ≥ 5 mm (Mann-Whitney, p = 0.518 and 0.870);, and ≥ 6 mm (Mann-Whitney, p = 0.994 and 0.879). Depression parameters were not associated with clinical attachment level ≥ 5 mm in this sample. Smoking was associated with loss of attachment ≥ 5 mm in the multivariable logistic regression model (odds ratio = 6.99, 95% confidence interval = 2.00-24.43). Conclusions In this sample, periodontal clinical parameters were not different between patients with MDD and control subjects. There was no association between depression and periodontitis.

Abstract: Objective: Major depressive disorder (MDD) is often underdiagnosed, undertreated, and associated with negative health outcomes. The current study examined the prevalence of MDD signs and symptoms in Brazil, including awareness, diagnosis, treatment, and the association of MDD with health outcomes. Methods: Data were collected from the 2011 National Health and Wellness Survey in Brazil (N = 12,000). Excluding those with bipolar disorder, respondents who met Patient Health Questionnaire-9 criteria for MDD (n = 1105) were compared with those not qualifying as having MDD or any depressive symptoms (n = 8684), analyzing separately those currently taking (n = 184) or not taking (n = 155) prescription medication for depression. Sociodemographics and health status, symptoms, experience of depression, diagnosis, MDD severity, pharmacotherapy, productivity impairment (Work Productivity and Activity Impairment questionnaire), health status (Short-Form 12, version 2), and health care resource use were measured. Results were weighted and projected to the Brazil adult population. Differences were measured with column proportion and mean tests for categorical and continuous outcomes, respectively. Results: MDD prevalence was 10.2%, with only 28.1% of the individuals with MDD diagnosed and 15.6% currently using prescription medication for depression. Males were especially likely to be unaware of MDD. Compared with non-MDD controls, patients with MDD (treated or untreated) reported significantly greater overall work impairment, worse mental and physical health status, and greater health care resource utilization (all P<0.05). There was a trend for worsening health outcomes with increasing MDD severity. Conclusions: These findings suggest that Brazilians may be underdiagnosed and undertreated for MDD. Individuals with MDD reported substantially poorer health outcomes, suggesting the need to increase MDD awareness, especially among males, and provide better access to treatment.

The aim of the present paper was to compare the efficacy and safety of duloxetine with paroxetine in the acute treatment of major depressive disorder (MDD). In a randomized, double-blind trial of 8 weeks active treatment, patients with non-psychotic MDD were randomized to duloxetine 60 mg ( n = 238) or paroxetine 20 mg ( n = 240) once daily. Efficacy was primarily measured on change in the 17-item Hamilton Rating Scale for Depression (HAMD17) using a non-inferiority test with a margin of 2.2. Secondary efficacy measures included the HAMD17 subscales, Hamilton Rating Scale for Anxiety, Clinical Global Impressions–Severity, Patient Global Impressions–Improvement, Somatic Symptoms Inventory and Visual Analog Scales (VAS) for pain. Safety measures included treatment-emergent adverse events (TEAE), vital signs, weight, laboratory analyses and electrocardiograms. Non-inferiority of duloxetine to paroxetine was demonstrated because the upper bound of the confidence interval for mean difference in HAMD17 change (0.71) was less than the non-inferiority margin. Secondary efficacy end-points did not differ significantly between treatments with the exception of VAS back pain, where the pooled mean was lower in the duloxetine group (17.1) compared with the paroxetine group (20.3, P = 0.048). No significant differences were observed in the number of early discontinuations and overall TEAE. However, significantly greater proportions of patients in the duloxetine group experienced nausea and palpitations. No clinically relevant changes in laboratory values, vital signs, weight or electrocardiograms were observed with either treatment. The present study verifies the utility of duloxetine as an efficacious and safe treatment for both emotional and physical symptoms of MDD in this predominantly Asian patient sample.

Abstract ., Background: Depression is highly prevalent and marked by a chronic and recurrent course. Despite being a major cause of disability worldwide, little is known regarding the determinants of its heterogeneous course. Machine learning techniques present an opportunity to develop tools to predict diagnosis and prognosis at an individual level., Methods: We examined baseline (2008-2010) and follow-up (2012-2014) data of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a large occupational cohort study. We implemented an elastic net regularization analysis with a 10-fold cross-validation procedure using socioeconomic and clinical factors as predictors to distinguish at follow-up: (1) depressed from non-depressed participants, (2) participants with incident depression from those who did not develop depression, and (3) participants with chronic (persistent or recurrent) depression from those without depression., Results: We assessed 15 105 and 13 922 participants at waves 1 and 2, respectively. The elastic net regularization model distinguished outcome levels in the test dataset with an area under the curve of 0.79 (95% CI 0.76-0.82), 0.71 (95% CI 0.66-0.77), 0.90 (95% CI 0.86-0.95) for analyses 1, 2, and 3, respectively., Conclusions: Diagnosis and prognosis related to depression can be predicted at an individual subject level by integrating low-cost variables, such as demographic and clinical data. Future studies should assess longer follow-up periods and combine biological predictors, such as genetics and blood biomarkers, to build more accurate tools to predict depression course.

• -Risk factors for a change from MDD to BD included female and younger age. • -Other risk factors for BD are low schooling level and lifetime use of illicit substances. • -We found that the diagnostic conversion rate from MDD to BD was 12.4%. The present study has two main aims: (1) To assess whether childhood trauma helps to differentiate Major Depressive Disorder (MDD) from Bipolar Disorder (BD) in a cross-sectional design; and (2) Describe the rate of conversion from MDD to BD, as well as the clinical and demographic predictors of conversion from MDD to BD in a prospective cohort design. We conducted a prospective cohort study in two phases, in the city of Pelotas, RS, Brazil. In the first phase, 565 subjects diagnosed with MDD, and 127 with BD according to the Mini International Neuropsychiatric Interview were included. In the second phase, only individuals with MDD were reevaluated for potential conversion to BD. The rate of conversion from MDD to BD in 3 years was 12.4%. Predictors of conversion from MDD to BD included lower educational level, use of illicit substances, younger age of the first depressive episode, and family history of BD. Childhood trauma was not a significant risk factor for conversion to BD in our prospective study. Our findings can contribute to the prevention and identification of conversion from MDD to BD, as well as to the establishment of more targeted therapeutic interventions, improving the prognosis of these individuals.

Major Depressive Disorder (MDD) is a disease that involves biological, psychological, and social interactions. Studies have shown the importance of genetics contribution to MDD development. The SCL6A4 protein (5HTTLPR) functions transporting serotonin, a neurotransmitter linked to mood and emotion, to the synaptic cleft. Hence, this study seeks, through a literature review, a better comprehension of the 5HTTLPR genetic variant association with MDD. For this purpose, a search was performed on the Virtual Health Library Portal for articles that related 5HTTLPR to MDD. Most of the articles found were conducted in the American continent, with one (1) study implemented in Brazil. 5HTTLPR associations were found regarding changes in the nervous system, pharmacology, and risk factors seen in MDD patients. When verifying the allelic distribution, the S allele had a higher frequency in most of the studies analyzed. Despite not finding a commonality in the different studies, the tremendous genetic variation found demonstrates the MDD complexity. For this reason, further studies in diverse populations should be conducted to assist in the understanding and treatment of the disease. [ABSTRACT FROM AUTHOR]

• People with Major Depressive Disorder tend to present a low adherence in programs and interventions involving physical activity. • Depression is associated with being less physically active and having a worse perceived health status. • Physical activity is a plausible nonpharmacologic treatment with evidence of efficacy as monotherapy as well as in combination with other antidepressant treatments. To evaluate the barriers, benefits and correlates of physical activity (PA) in outpatients with Major Depressive Disorder (MDD). Data were collected from outpatients under treatment for MDD at Hospital de Clínicas de Porto Alegre. Barriers and benefits were assessed with the Exercise Barriers/Benefits Scale (EBBS). Objective and self-reported PA were assessed with pedometers and the International Physical Activity Questionnaire (IPAQ), respectively. The sample consisted of 65 outpatients (82% female; mean age = 50.9 years; SD = 10.1). Improvement in physical performance was the most reported benefit (mean = 3.00; SD = 0.3) while the most reported barrier was physical exertion (mean = 2.95; SD = 0.4). Depression symptom severity was negatively correlated with life enhancement (r = -0.337; p = 0.009), physical performance (r =-0.348; p = 0.007), psychological outlook (r =-0.364; p = 0.005), social interaction (r =-0.317; p = 0.015) and preventive health (r =-0.352; p = 0.007). Physical exertion is the most perceived barrier for PA in people with MDD. Symptom severity is associated with higher barrier levels , whilst higher current PA levels are associated with more benefits and lesser barriers. Interventions targeting PA promotion should consider the identified benefits and barriers when developing PA programs for people with MDD in outpatient settings. [ABSTRACT FROM AUTHOR]

Objective: We investigated whether ideal cardiovascular health (ICH), a metric proposed by the American Heart Association, predicts depression development., Methods: Cohort analysis from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Adults with no current depression and other common mental disorders, cardiovascular diseases, and antidepressant drug use at baseline had their ICH (composite score of smoking, dietary habits, body mass index, blood pressure, fasting glucose, cholesterol, and physical activity) assessed and classified into poor, intermediate, and optimal. Depression was assessed using the Clinical Interview Schedule-Revised (CIS-R). Poisson regression models, adjusted for sociodemographic factors and alcohol consumption, were employed. Stratified analyses were performed for age and sex., Results: We included 9214 participants (mean age 52 ± 9 years, 48.6% women). Overall depression incidence at 3.8-year follow-up was 1.5%. Intermediate and poor ICH significantly increased the risk rate (RR) of developing depression (2.48 [95%CI 1.06-5.78] and 3 [1.28-7.03], respectively) at a 3.8-year follow-up. Higher ICH scores decreased the rate of depression development (RR = 0.84 [0.73-0.96] per metric). Stratified analyses were significant for women and adults < 55 years old., Conclusions: Poor cardiovascular health tripled depression risk at follow-up in otherwise healthy adults. Ameliorating cardiovascular health might decrease depression risk development., (© 2019 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: The aims of the study were to investigate the prevalence of long-term use of benzodiazepines in patients taking antidepressants and to identify the risk factors associated with the prolonged use of benzodiazepines., Design: Cross-sectional study., Setting: Public health system in Brazil., Participants: Outpatients using antidepressants from January 2008 to December 2009 were included. The data were obtained from pharmacy databases and medical records. All individuals in the database were included in the study and were classified into two categories: (1) patients who had not used benzodiazepines combined with antidepressants or had combined the use of antidepressants with benzodiazepines for a short period (up to 4 weeks), and (2) those who used antidepressants plus benzodiazepines for a longer period (more than 4 weeks)., Main Outcome Measure: The outcome measure is prolonged use of benzodiazepines (more than 4 weeks). We conducted a multivariate analysis to identify the factors associated with prolonged use of benzodiazepines., Results: Forty per cent of the 870 patients evaluated had prolonged use of benzodiazepines (more than 4 weeks). The risk factors associated with prolonged use were age above 35 years (prevalence ratio (PR): 2.18, 95% CI 1.55 to 3.06, P<0.001), female sex (PR: 1.47, 95% CI 1.07 to 2.02, P=0.019), diagnosis at least 3 years prior (PR: 2.1, 95% CI 1.6 to 2.8, P<0.001), use of selective serotonin reuptake inhibitor antidepressants (PR: 1.7, 95% CI 1.3 to 2.2, P<0.001) and having a prescription from a psychiatrist (PR: 6.5, 95% CI 3.2 to 13.2, P<0.001)., Conclusions: Prolonged use of benzodiazepines occurs more frequently in women, adults diagnosed several years earlier, users of selective serotonin reuptake inhibitor antidepressants and those who received a prescription from a psychiatrist. Education of clinicians, especially with regard to these populations, may decrease the overuse and misuse of benzodiazepines., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The present study aimed to determine whether any gender-related difference exists concerning oxidative stress parameters in a population of 231 subjects, and if these changes might be related to gender-associated differences in major depressive disorder (MDD) or bipolar disorder (BD) vulnerability. This is a case-control nested in a population-based study. The initial psychopathology screen was performed with the Mini-International Neuropsychiatric Interview and the diagnostic was further confirmed with the Structured Clinical Interview for DSM-IV. Blood samples were obtained after the interview and the oxidative stress parameters such as uric acid, advanced oxidation protein product (PCC) and lipid hydroperoxides (TBARS) were determined. Our results indicated a higher prevalence of MDD and BD in women when compared to men. In addition, significant gender differences were found in the levels of PCC (0.27±0.27 vs. 0.40±0.31nmol CO/mg protein, men vs. women, respectively; P=0.02) and uric acid (4.88±1.39mg/dL vs. 3.53±1.02mg/dL, men vs. women, respectively; P=0.0001), but not in TBARS (0.013±0.01nmol/mg of protein vs. 0.017±0.02nmol/mg of protein, men vs. women respectively; P=0.243). After sample stratification by gender, no association was found between oxidative stress parameters and clinical diagnosis of MDD and BD for women (P=0.516 for PCC; P=0.620 for TBARS P=0.727 for uric acid) and men (P=0.367 for PCC; P=0.372 for TBARS P=0.664 for uric acid). In this study, women seem more susceptible to oxidative stress than male. However, these gender-based differences do not seem to provide a biochemical basis for the epidemiologic differences in mood disorders susceptibility between sexes., (Copyright © 2013 Elsevier Masson SAS.
