Basic assistance for mental health in Northeast Brazil

Introduction: Brazilian northeast region is historically affected by socioeconomic problems that made this region more needful for strategies regarding to psychiatric disorders assistance. Methods: This study includes original analysis based on data of secondary level health assistance, extracted from Brazil's Hospitalar Information System, Basic Assistance Information System and Brazilian Institute of Geographic and Statistics. Results: Between 2008 and 2010, more than two hundred million dollars were spent by Brazilian federal government to achieve better quality in the assistance for mental health in Northeast. The service network responsible for the treatment of mental disorders in primary care involves a wide range of professionals and establishments. Conclusion: In northeastern Brazil, socioeconomic and geographic conditions contribute to a particular state of vulnerability for the development of psychopathologies. The association of primary care and an integrated network of public health, however, have improved the attention to mental disordersin this region.

Effects of acute creatine supplementation on iron homeostasis and uric acid-based antioxidant capacity of plasma after wingate test

Background: Dietary creatine has been largely used as an ergogenic aid to improve strength and athletic performance, especially in short-term and high energy-demanding anaerobic exercise. Recent findings have also suggested a possible antioxidant role for creatine in muscle tissues during exercise. Here we evaluate the effects of a 1-week regimen of 20 g/day creatine supplementation on the plasma antioxidant capacity, free and heme iron content, and uric acid and lipid peroxidation levels of young subjects (23.1 +/- 5.8 years old) immediately before and 5 and 60 min after the exhaustive Wingate test. Results: Maximum anaerobic power was improved by acute creatine supplementation (10.5 %), but it was accompanied by a 2.4-fold increase in pro-oxidant free iron ions in the plasma. However, potential iron-driven oxidative insult was adequately counterbalanced by proportional increases in antioxidant ferric-reducing activity in plasma (FRAP), leading to unaltered lipid peroxidation levels. Interestingly, the FRAP index, found to be highly dependent on uric acid levels in the placebo group, also had an additional contribution from other circulating metabolites in creatine-fed subjects. Conclusions: Our data suggest that acute creatine supplementation improved the anaerobic performance of athletes and limited short-term oxidative insults, since creatine-induced iron overload was efficiently circumvented by acquired FRAP capacity attributed to: overproduction of uric acid in energy-depleted muscles (as an end-product of purine metabolism and a powerful iron chelating agent) and inherent antioxidant activity of creatine.

Summary of the II Brazilian Guideline Update on Acute Heart Failure 2009/2011

In the past two years we observed several changes in the diagnostic and therapeutic approach of patients with acute heart failure (acute HF), which led us to the need of performing a summary update of the II Brazilian Guidelines on Acute Heart Failure 2009. In the diagnostic evaluation, the diagnostic flowchart was simplified and the role of clinical assessment and echocardiography was enhanced. In the clinical-hemodynamic evaluation on admission, the hemodynamic echocardiography gained prominence as an aid to define this condition in patients with acute HF in the emergency room. In the prognostic evaluation, the role of biomarkers was better established and the criteria and prognostic value of the cardiorenal syndrome was better defined. The therapeutic approach flowcharts were revised, and are now simpler and more objective. Among the advances in drug therapy, the safety and importance of the maintenance or introduction of beta-blockers in the admission treatment are highlighted. Anticoagulation, according to new evidence, gained a wider range of indications. The presentation hemodynamic models of acute pulmonary edema were well established, with their different therapeutic approaches, as well as new levels of indication and evidence. In the surgical treatment of acute HF, CABG, the approach to mechanical lesions and heart transplantation were reviewed and updated. This update strengthens the II Brazilian Guidelines on Acute Heart Failure to keep it updated and refreshed. All clinical cardiologists who deal with patients with acute HF will find, in the guidelines and its summary, important tools to help them with the clinical practice for better diagnosis and treatment of their patients.
