Suicide risk in people living with AIDS/HIV: the effect of childhood trauma is mediated by mental disorders and social vulnerability.

Suicide is an important problem in people living with HIV/AIDS (PLWHA). The importance of mental disorders and social vulnerability on suicidal behaviors is described in the literature; however, the impact of childhood traumatic events in this scenario is not clear. The aim of this study was to verify the mediation effect of mental disorder comorbidities and social vulnerability in association with childhood trauma intensity and suicide risk level. This cross-sectional study of HIV-positive outpatients was conducted in a specialized care service in the city of Pelotas in Southern Brazil. Sociodemographic data and HIV-related information were collected and the Childhood Trauma Questionnaire was applied. A total of 364 patients underwent psychiatric evaluation using MINI Plus including module C of suicide risk severity. Suicide risk was present in 39.3% of the sample. The relation between childhood traumatic events and the level of suicide risk is mediated by mental disorder comorbidities and socioeconomic vulnerability. Specific psychosocial interventions in PLWHA should consider the potential role of abusive traumatic experiences in the current mental health conditions and suicidal behaviors.

Depression and diagnosis of neurocognitive impairment in HIV-positive patients.

Neurocognitive impairment (NCI) is frequently observed in patients infected with human immunodeficiency virus (HIV) and results from the compromise of subcortical brain structures by the virus. The manifestations of NCI range from asymptomatic impairment to dementia. In addition to cognitive impairment resulting from HIV infection, other factors such as depression are associated with the loss of cognitive functions. The aim of this study was to estimate the prevalence of NCI in HIV-positive patients in a city in southern Brazil and to establish possible associations for the prevalence of NCI with HIV-related and other risk factors. This cross-sectional study of HIV-positive outpatients was conducted in a specialized care service in the city of Pelotas in Southern Brazil. Sociodemographic data and HIV-related information were collected, and all patients underwent psychiatric and neurocognitive evaluations. The prevalence of NCI among the 392 patients was 54.1% when tracked using the IHDS (International HIV Dementia Scale) and 36.2% when the IHDS was associated with a battery of complementary tests. A bivariate analysis suggested an association of NCI with gender, age, educational level, depression, current CD4 count and lowest CD4 count. The association of NCI with depression remained in the Poisson regression (PR=1.96, 95%CI=1.12-3.42). The prevalence of cognitive impairment in HIV-positive patients estimated in this study is in accordance with international and Brazilian data. Of the factors analyzed, depression showed the greatest evidence of association with neurocognitive loss. Based on our findings, the inclusion of instruments to evaluate depression in our services for patients with HIV and acquired immunodeficiency syndrome (AIDS) is recommended.

Two studies on suicidality in the postpartum.

OBJECTIVE: Research in the prevalence of and risk factors for suicidality in the postpartum is extremely limited. We present here data on the prevalence of and factors associated with suicidality from two postpartum samples. METHOD: The first sample (SC) comprised 317 women consecutively screened for a trial of psychotherapy for postpartum depression. The second sample was a population-based (PB) sample of 386 women. We used the Mini-International Neuropsychiatric Interview (MINI) to assess suicidality in the SC sample and the self-harm question of the Beck Depression Inventory (BDI9) in the PB sample. RESULTS: According to the MINI and the BDI9, prevalence of high suicide risk was 5.7% and 11.1%, respectively, in the SC sample. Previous suicide attempts and a positive BDI were retained as predictors of suicidality. The BDI9 indicated suicidality in 8.3% of the 386 women in the PB sample; a positive BDI was retained in the multivariate analysis as a risk of suicidality. CONCLUSION: Clinicians should enquire vigorously about suicidality in women presenting with depressive symptoms or previous suicide attempts in the postpartum.

Is paternal postpartum depression associated with maternal postpartum depression? Population-based study in Brazil.

OBJECTIVE: To describe the prevalence of paternal postpartum depression (PPD) as well as its association with maternal PPD. METHOD: A population-based random sample of 386 couples was assessed from the sixth to the 12th week postpartum for demographic characteristics, alcohol misuse (AUDIT) and depressive symptoms [Beck Depression Inventory (BDI)]. Logistic regression was employed to control for potential confounders. RESULTS: In the BDI, 26.3% of mothers and 11.9% of fathers scored above the selected threshold of 10. Mild maternal depression [odds ratio (OR) 3.31, 95% CI 1.52-7.20] and moderate to severe maternal depression (OR 8.44, 95% CI 3.53-20.21) were associated with paternal PPD. CONCLUSION: Paternal PPD is a clinically meaningful phenomenon. Fathers should be evaluated for mood disorders in the postpartum, especially when their partner is depressed.
