The vulnerable male, or the sex ratio among fetal deaths in Brazil

Some studies indicate the existence of innate male vulnerabilities, especially during the perinatal period. The current study is a cross-sectional analysis of fetal mortality in Brazil according to sex from 2000 to 2009, stratified by maternal characteristics (age, schooling, and gestational age), using Ministry of Health data (DATASUS). The analysis included all fetal deaths from 2000 to 2009, except when the sex of the fetus was not recorded. The male/female sex ratio (SR) for all fetal deaths was 1.188. Analysis of maternal characteristics showed that the SR was statistically higher (p < 0.01) in mothers that were younger (10-14 years), had no formal schooling, and with gestational age < 22 weeks. The study showed a statistically higher-than-expected SR (p < 0.01) for 13 underlying causes of death and a lower SR for two others. The results suggest a potential innate male vulnerability.

Impact of comorbid migraine on the clinical course of bipolar disorder

Background: Recent evidence suggests an association between migraine and bipolar disorder (BD), although the impact of this association in the clinical course of BD is relatively unknown. Objective: This study aimed to compare 2 groups of individuals with BD (with vs without comorbid migraine) and evaluate differences in severity of clinical course. Methods: Three hundred thirty-nine adults with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition defined bipolar or II disorder were enrolled and divided into 2 groups: with and without comorbid migraine. Demographic and clinical data were obtained using standardized interviews. Results: Patients with comorbid migraines had more mood episodes, especially those with depressive polarity. In addition, comorbid migraine was associated with a higher prevalence of psychiatric and general medical comorbidities. Differences between the 2 groups in number of lifetime hospitalizations for depression/mania, rates of rapid cycling, and history of suicide attempts were not observed after Bonferroni correction. Conclusions: Comorbid migraine seems to be associated with poor outcomes in BD. Additional studies should be conducted to investigate shared vulnerabilities and pathophysiologic mechanisms as well as treatment optimization of both illnesses. (C) 2012 Elsevier Inc.

Depression in children and adolescents: family narratives in Brazilian primary attention

Background: The incidence of depression in children and adolescents still increasing and this disorder is now a major public health challenge worldwide. The Psychiatric Reform suggested an end to the fragmented and inefficient service by proposing integrated and quality care. In this context, family narratives are a way to recognize vulnerabilities and provide psychopathology prevention in primary care. Methods: Two medical databases (LILACS and SciELO) were surveyed and 14 texts published between 2004 and 2011 were selected and reviewed. Results and discussion: Children and adolescents are nowadays exposed to several stressing factors, in addition to natural vulnerabilities of this age group. Prevention is associated with a qualified hearing of family narratives in primary care and healthcare professionals should be able to perceive said and unsaid elements across the speech. Conclusion: In spite of the advances about children and adolescents mental health, some procedures must be adapted to achieve an efficient mental health policy though analyzing family discourse.

Resíduos sólidos urbanos: impactos socioambientais e perspectiva de manejo sustentável com inclusão social

Com a Rio+20 retoma-se a discussão de estratégias para conciliar desenvolvimento com proteção dos ecossistemas. Um tema apenas tangenciado nessas discussões é o gerenciamento dos resíduos sólidos urbanos. Diante da institucionalização da Política Nacional de Resíduos Sólidos, busca-se contribuir para esse debate, bem como apontar caminhos para o enfrentamento dessa questão, privilegiando a inclusão social. Para isso, foram utilizados documentos e informações sobre a gestão de resíduos sólidos, e a literatura científica especializada. Observa-se que o inadequado gerenciamento dos resíduos sólidos gera impactos imediatos no ambiente e na saúde, assim como contribui para mudanças climáticas. Considerando as limitações das opções de destinação final para os resíduos, é imprescindível minimizar as quantidades produzidas por meio da redução, reutilização e reciclagem. Nesse contexto, destaca-se o papel dos catadores, que vêm realizando um trabalho de grande importância ambiental. Dadas as fragilidades desse segmento populacional, é preciso delinear políticas públicas que tornem a atividade de catação mais digna e com menos riscos e que, ao mesmo tempo, garantam renda, para assim caminhar rumo a um desenvolvimento mais saudável, justo e sustentável.
