RESUMO

OBJECTIVES: The aims of this article were to analyse the burden of NCDs and their RFs in the Mercosur countries between 1990 and 2019 and to project mortality trends for 2030. STUDY DESIGN: Epidemiological study of time series. METHODS: The present study used data from the Global Burden of Disease study. The absolute number of deaths, mortality rates, disability-adjusted life years, years of life lost, years lived with disability and the burden of premature mortality by NCD attributable to the RFs were evaluated. Projections were made up to 2030. Age-standardised rates were used to draw comparisons by years and by countries. The analysis was conducted using the RStudio software. RESULTS: Between 1990 and 2019, a decrease was found in the premature mortality rates caused by NCDs in all the countries, except for Paraguay, which remained stable. When analysing premature mortality rates due to NCDs up to 2030, it was predicted that none of the countries would achieve the sustainable development goal of a one-third reduction in premature mortality by NCDs. Regarding the impacts of the RFs for NCDs, smoking, dietary risks, high blood pressure (BP) and high body mass index (BMI) were the main risks attributable to premature deaths due to NCDs. CONCLUSIONS: The results showed that mortality rates are declining in Mercosur countries; however, none of the countries are predicted to achieve the sustainable development goal of a one-third reduction in mortality due to NCDs by 2030. In addition to access to adequate treatment, progress is required in public regulation actions to reduce RFs, such as smoking, dietary risks, high BP and high BMI.

RESUMO

Cellular automata (CA) are important as prototypical, spatially extended, discrete dynamical systems. Because the problem of forecasting dynamic behavior of CA is undecidable, various parameter-based approximations have been developed to address the problem. Out of the analysis of the most important parameters available to this end we proposed some guidelines that should be followed when defining a parameter of that kind. Based upon the guidelines, new parameters were proposed and a set of five parameters was selected; two of them were drawn from the literature and three are new ones, defined here. This article presents all of them and makes their qualities evident. Then, two results are described, related to the use of the parameter set in the Elementary Rule Space: a phase transition diagram, and some general heuristics for forecasting the dynamics of one-dimensional CA. Finally, as an example of the application of the selected parameters in high cardinality spaces, results are presented from experiments involving the evolution of radius-3 CA in the Density Classification Task, and radius-2 CA in the Synchronization Task.

RESUMO

A new neural network model - the GasNet - has been recently reported in the literature, which, in addition to the traditional electric type, point-to-point communication between units, also uses communication through a diffilsable chemical modulator. Here we assess the applicability of this model in three different scenarios, the XOR problem, a food gathering task for a simulated robot, and a docking task for a virtual spaceship. All of them represent discrete domains, a contrast with the one where the GasNet was originally introduced, which had an essentially continuous nature. These scenarios are well-known benchmark problems from the literature and, since they exhibit varying degrees of complexity, they impose distinct performance demands on the GasNet. The experiments were primarily intended to better understand the model, by extending the original problem domain where GasNet was introduced. The results reported point at some difficulties with the current GasNet model.

RESUMO

A 45 year-old woman complaining of heart failure symptoms (New York Heart Association--class III) and a non typical thoracic pain was submitted to a transthoracic echocardiogram which showed a very dilated coronary artery and a fistula to the right atrium. The angiograms confirmed the same findings. She underwent open heart surgery which confirmed the diagnosis. Fistula ligation was then undertaken. She remains symptom-free three years after the operation.

RESUMO

PURPOSE: To describe a technique with a thin drainage system placed behind the heart, avoiding reoperation caused by tamponade due to pericardial effusion in patients who undergo open heart surgery. METHODS: We studied 59 patients, average age of 50 years. Twenty-six (44%) patients had undergone CABG, 25 (42%) valvar procedures and 8 (14%) different procedures. The control group were 20 patients, average age 44 years. Nine (45%) underwent CABG, 6 (30%) valvar procedures and 5 (25%) other procedures. Every patient was submitted to echocardiographic study to verify presence of pericardial effusion after operation. RESULTS: There was one patient with pericardial effusion with 8mm in the study group. Six patients showed pericardial effusion in the control group. The control group had mean drainage flow of 320 +/- 110ml and average permanence time was 45 +/- 10h. The study group had mean drainage flow of 410 +/- 122ml, the average permanence time was 46 +/- 10h. There was statistic difference between both groups when we compared the frequency of pericardial effusion. CONCLUSION: This drainage system reduces pericardial effusion comparing with the literature and causes little discomfort to the patient. The fixed rule to remove the drains did not present more discomfort to the patient and there were no complications related to its permanence.

RESUMO

The pacemaker with rate-responsiveness was a great advance in cardiac stimulation, however, the choice of the best biosensor is still object of research. A 35 year-old woman with a responsive pacemaker implanted due to a complete heart block after interventricular septal defect surgical correction was admitted. The pacemaker showed improper cronothropic response with high frequency due to biosensing malfunction. Malfunction related to muscle stimulation in the generator pocket and a high response rate. A palliative procedure was made until the end of pregnancy, by reducing the sensitivity of biosensing.

RESUMO

It is shown how the entire dynamics of a class of evolutionary systems can be used to perform a computation. The argument is constructive by presenting a Turing-machine-based set-up implemented in Enact, an artificial-life world embedded in a family of cellular automata; in this system, a population of agents move about in a two-dimensional space, interacting with their environment, reproducing and undergoing developmental and coevolutionary processes. As a byproduct, the paper also serves to characterise the main model of computation underlying Enact. This model is essentially parallel, and relies upon the machinery defined by the artificial-life processes. According to the model, a particular computation is considered to have been performed, if and only if, for some initial population and environmental configuration, at least one agent has developed into a state configuration that is insensitive to any further environmental interactions; in this situation, if the computation involved is a function, this individual has the result. If the population ever vanishes, or if the environment becomes short of the resources needed for development, the cellular space has to be re-initialized, and the process iterated. The presentation relies on the implementation of a function that recognises a particular context-free language. Implications of the model of computation are then discussed, in particular the model of coupled computations suggested by it.
