Amazon rainforest modulation of water security in the Pantanal wetland.

The Pantanal is a large wetland mainly located in Brazil, whose natural resources are important for local, regional and global economies. Many human activities in the region rely on Pantanal's ecosystem services including cattle breeding for beef production, professional and touristic fishing, and contemplative tourism. The conservation of natural resources and ecosystems services provided by the Pantanal wetland must consider strategies for water security. We explored precipitation data from 1926 to 2016 provided by a regional network of rain gauge stations managed by the Brazilian Government. A timeseries obtained by dividing the monthly accumulated-rainfall by the number of rainy days indicated a positive trend of the mean rate of rainy days (mm/day) for the studied period in all seasons. We assessed the linkage of Pantanal's rainfall patterns with large-scale climate data in South America provided by NOAA/ESRL from 1949 to 2016. Analysis of spatiotemporal correlation maps indicated that, in agreement with previous studies, the Amazon biome plays a significant role in controlling summer rainfall in the Pantanal. Based on these spatiotemporal maps, a multi-linear regression model was built to predict the mean rate of summer rainy days in Pantanal by 2100, relative to the 1961-1990 mean reference. We found that the deforestation of the Amazon rainforest has profound implications for water security and the conservation of Pantanal's ecosystem services.

Prevalence of cardiac arrhythmias during and after pregnancy in women with Chagas' disease without apparent heart disease.

OBJECTIVE: To evaluate cardiac arrhythmias during and after pregnancy in women with Chagas' disease without apparent heart disease using dynamic electrocardiography. METHODS: Twenty pregnant women with Chagas' disease without apparent heart disease aged 19 to 42 years (26.96 +/- 3.6) and a control group of 20 non-chagasic pregnant patients aged 16 to 34 years (22.5 +/- 4.8). The patients were submitted to passive hemagglutination and indirect immunofluorescence for the detection of Trypanosoma cruzi evaluation, and electrocardiography, echocardiography and 24-h dynamic electrocardiography. RESULTS: Supraventricular premature depolarizations were observed in 18 (90%) patients and ventricular premature depolarization in 11 (55%) patients of both groups during pregnancy. After delivery, supraventricular premature depolarizations were present in 13 (60%) chagasic patients and in 16 (89.4%) control patients (P

Crianças e adolescentes usuários de substâncias no serviço de emergência psiquiátrica / Children and adolescents who are substances users in the psychiatric emergency service

Objetivo Descrever as características de crianças e adolescentes que utilizaram o serviço de emergência psiquiátrica devido aos transtornos pelo uso de substâncias analisando a freqüência e desfechos dos atendimentos. Métodos Estudo transversal realizado em serviço de emergência psiquiátrica sendo considerado o atendimento aos menores de 18 anos correspondentes ao uso de substâncias. Resultados Foram realizados 4.198 atendimentos de emergência psiquiátrica para crianças e adolescentes. Destes, 1.007 eram por problemas relacionados ao uso substâncias, com idade prevalente de 12 aos 17 anos, com predomínio da cor branca, cursando ensino fundamental, religião católica e policonsumo. A maioria foi internada ou recebeu alta. Conclusão Foi possível caracterizar os atendimentos de emergência psiquiátrica, destacando a idade precoce, o policonsumo e a não continuidade de tratamento como aspectos críticos...

Objective To describe characteristics of children and adolescents who used the psychiatric emergency service because of disorders caused by substance use. We analyzed frequencies and care outcomes. Methods This cross-sectional study was carried out in a psychiatric emergency service. Care was delivered to patients 18 years of age and younger who were substance users. Results We performed 4,198 cares delivered at a psychiatric emergency service for children and adolescents. Of these, 1,007 were due to problems related to substance use. The prevalent age was 12 to 17 years. Most participants were white, attended elementary education, were Catholic, and used multiple substances. The majority of participants were hospitalized or discharged. Conclusion This study permitted characterization of psychiatric emergency services provided to children and adolescents. Critical aspects were young age, use of multiple substances, and nonadherence to treatment...

Causas básicas de morte em chagásicos idosos / Basic causes of death in elderly chagasic patients

Determinaram-se, ocm bases em dados clínicos e necroscópicos, as causas básicas de morte de 100 chagásicos idosos (grupo A), 100 idosos näo chagásicos (grupo B) e 100 chagásicos näo idosos (grupo C). Em relaçäo a B, o grupo A teve um número significativamente maior de mortes por cardiopatica hagásica crôn e "mega" digestivos e menor de neoplasias malignas. Quando comparado a C, o grupo A teve, em grua significativo, mortalidade maior por enfisema pulmonar e neoplasias malignas e menor por cardiopatia chagásica crônica. Esta causou 26 óbitos súbitos inesperados entre os näo idosos, mas nenhum entre os idosos

Prevalência das arritmias cardíacas em portadoras de doença de Chagas, sem cardiopatia aparente durante e após a gravidez / Prevalence of cardiac arrhythmias during and after pregnancy in women with Chagas' disease without apparent heart disease

OBJECTIVE: To evaluate cardiac arrhythmias during and after pregnancy in women with Chagas' disease without apparent heart disease using dynamic electrocardiography. METHODS: Twenty pregnant women with Chagas' disease without apparent heart disease aged 19 to 42 years (26.96 ± 3.6) and a control group of 20 non-chagasic pregnant patients aged 16 to 34 years (22.5 ± 4.8). The patients were submitted to passive hemagglutination and indirect immunofluorescence for the detection of Trypanosoma cruzi evaluation, and electrocardiography, echocardiography and 24-h dynamic electrocardiography. RESULTS: Supraventricular premature depolarizations were observed in 18 (90 percent) patients and ventricular premature depolarization in 11 (55 percent) patients of both groups during pregnancy. After delivery, supraventricular premature depolarizations were present in 13 (60 percent) chagasic patients and in 16 (89.4 percent) control patients (P<=0.05). Ventricular premature depolarization were observed in 9 (45 percent) chagasic patients and 11 (57.8 percent) control patients. CONCLUSION: The prevalence of ventricular premature depolarization was similar for the chagasic and control groups during and after pregnancy. The incidence of supraventricular premature depolarizations was similar in the two groups during pregnancy, while after delivery a predominance was observed in the control group compared to the chagasic group
