Waist circumference and waist circumference to height ratios of Kaingang indigenous adolescents from the State of Rio Grande do Sul, Brazil

The aim of this study was to describe the distribution of waist circumference (WC) and WC to height (WCTH) values among Kaingang indigenous adolescents in order to estimate the prevalence of high WCTH values and evaluate the correlation between WC and WCTH and body mass index (BMI)-for-age. A total of 1,803 indigenous adolescents were evaluated using a school-based cross-sectional study. WCTH values > 0.5 were considered high. Higher mean WC and WCTH values were observed for girls in all age categories. WCTH values > 0.5 were observed in 25.68% of the overall sample of adolescents. Mean WC and WCTH values were significantly higher for adolescents with BMI/age z-scores > 2 than for those with normal z-scores. The correlation coefficients of WC and WCTH for BMI/age were r = 0.68 and 0.76, respectively, for boys, and r = 0.79 and 0.80, respectively, for girls. This study highlights elevated mean WC and WCTH values and high prevalence of abdominal obesity among Kaingang indigenous adolescents.

The burden of dengue: Jundiai, Brazil - January 2010

Objective: To study the antibody prevalence against dengue in the municipality of Jundiai, Sao Paulo, Brazil, due to the low number of official confirmed autochthonous cases. Methods: A serological study on dengue infection was conducted during January 2010 and previous reports on dengue and entomological surveillance during that period were reviewed. Results: A prevalence of 7.8% IgG positive (68:876) was found. Furthermore, based on the detection of IgM antibodies in five samples, it was observed that the incidence of dengue in the city at the time of the survey contrasts with the absence of notifications by local health authorities over the same period of time. Conclusion: These results highlight the discrepancies between the actual and the detected number of dengue infections, possibly due to significant numbers of asymptomatic infections aggravated by difficulties with dengue clinical diagnosis.

Bioethics and Mental Health: The Rights of Patients With a Disorder

Bioethics can be included in the context of psychiatric patients' recovery of dignity and rights, creating a therapeutic interface of social rehabilitation, respect and closeness between professionals and the treated persons. The completion of the analysis of the facts occurred by reviewing 22 articles dated between 1999-2011, from a prior reading, selecting the ones that mention bioethics and mental health. Before the Psychiatric Reform, often, a lack of commitment to the mentally ill was noticed, isolating the patient from a social life. Before the Psychiatric Reform, often, a lack of commitment to the mentally ill was noticed by isolating the patient from a social life. After the Reform, the person with mental illness began to receive a more attentive care. It can be concluded that the Reform tried to bring life to those who had no respect and attention, these patients who needed to be included in a social and urban interaction.
