Introduction: Suicide is one of the leading causes of death, with a trend for its increase in Brazil in past decades. This study aimed to review the characteristics of suicides in Brazilian postmortem studies. Methods: Studies investigating suicide deaths in Brazil, and based on autopsy or psychological autopsy were included. Proportions were pooled across studies with the use of random and fixed effects models. Results: 6777 references were retrieved from six databases (searches up to January, 2023), and 45 studies included. In autopsy studies (k = 37, n = 16,231), substance use at toxicological analysis was found in 36.42% of cases (95% CI: 30.05–43.32), previous suicide attempts in 23.92% (95% CI: 6.73–57.78). In psychological autopsy studies (k = 8, n = 139), previous suicide attempts were reported in 28.09% (95% CI: 19.74–38.28), psychiatric conditions/symptoms in 90.67% (95% CI: 67.79–97.82), family history of suicidality in 21.33% (95% CI: 13.5–32.03). Most suicide deaths were reported in males and took place at the victim's home, hanging was the most frequent suicide method. Included studies presented significant limitations in quality assessment. Conclusion: Future studies should present more robust methodology, including bigger samples, the use of controls, and validated methodology. [ABSTRACT FROM AUTHOR]

Background: Little is known about specific mood symptoms that may confer risk for suicidal ideation (SI) among patients with bipolar disorder (BD). We evaluated prospectively whether particular symptoms of depression and mania precede the onset or worsening of SI, among adults with or without a history of a suicide attempt.Methods: We examined prospective data from a large (N = 2,741) cohort of patients participating in the Systematic Treatment Enhancement Program for BD (STEP-BD). We evaluated history of suicide attempts at baseline, and symptoms of depression and mania at baseline and follow-up visits. Hierarchical linear modeling tested whether specific mood symptoms predicted subsequent levels of SI, and whether the strength of the associations differed based on suicide attempt history, after accounting for the influence of other mood symptoms and current SI.Results: Beyond overall current depression and mania symptom severity, baseline SI, and illness characteristics, several mood symptoms, including guilt, reduced self-esteem, psychomotor retardation and agitation, increases in appetite, and distractibility predicted more severe levels of subsequent SI. Problems with concentration, distraction, sleep loss and decreased need for sleep predicted subsequent SI more strongly among individuals with a suicide attempt history.Conclusions: Several specific mood symptoms may confer risk for the onset or worsening of SI among treatment-seeking patients with BD. Individuals with a previous suicide attempt may be at greater risk in part due to greater reactivity to certain mood symptoms in the form of SI. However, overall, effect sizes were small, suggesting the need to identify additional proximal predictors of SI. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To evaluate the prevalence of episodes of mania and hypomania, as well as associated factors and comorbidities among adults 18 to 24years old in the city of Pelotas, Brazil. Method: This is a cross-sectional population-based study. The sample was selected through conglomerates, and episodes of mania and hypomania were assessed using the Mini International Neuropsychiatric. Results: The sample consisted of 1560 subjects. The lifetime prevalence of manic and hypomanic episodes was 7.5% and 5.3%, respectively. Subjects with (hypo)manic episodes had a higher prevalence of anxiety disorders, substance abuse and suicidality. Limitation: The high rate of (hypo)mania may to some extent reflect diagnostic error. Conclusion: Such high prevalence of (hypo)mania may nonetheless be valid as it was associated with corresponding rates of comorbidity and suicidality. [Copyright &y& Elsevier]
