Fisioterapia respiratoria na pressao intracraniana de pacientes graves internados em unidade de terapia intensiva: revisao sistematica

Objetivo: Analisar os desfechos aumento/diminuição da pressão intracraniana e/ou queda da pressão de perfusão cerebral, proporcionados pela fisioterapia respiratória em pacientes graves assistidos em unidade de terapia intensiva. Métodos: Por meio de uma revisão sistemática da literatura, foram selecionados ensaios clínicos publicados entre 2002 e 2012. A busca envolveu as bases de dados LILACS, SciELO, MedLine e PEDro, usando os descritores physical therapy, physiotherapy, respiratory therapy e randomized controlled trials em cruzamento com o descritor intracranial pressure. Resultados: Foram incluídos 5 estudos, que somaram 164 pacientes, com média de idade entre 25 e 65 anos, e que indicaram que as manobras de fisioterapia respiratória aumentaram significativamente a pressão intracraniana, sem alterar a pressão de perfusão cerebral. Os artigos abordaram as técnicas de vibração, vibrocompressão, tapotagem, drenagem postural, além da manobra de aspiração intratraqueal. Todos os pacientes estavam sob ventilação mecânica invasiva. Conclusão: A fisioterapia respiratória promove aumento da pressão intracraniana. Os estudos sugerem que não há repercussões hemodinâmicas e respiratórias a curto prazo ou alteração da pressão de perfusão cerebral. Entretanto, não há estudos que avaliem desfechos clínicos e que assegurem a segurança das manobras.

Patient with a Starr-Edwards Prosthesis in the Aortic Position for 40 Years

Herein is reported the case of a patient who presented initially with aortic insufficiency and a fistula between the sinus of Valsalva and right atrium when aged 31 years. Closure of the fistula and replacement of the aortic valve with a Starr-Edwards A-9 caged-ball prosthesis was performed in 1972, since when the valve has survived for 40 years without dysfunction. This is one of the longest follow ups of the Starr-Edwards prosthesis reported, and highlights the possibility of acceptable valve performance over long periods of time.

Respostas cardiovasculares ao exercício resistido em hipertensos: uma revisão sistemática

Adopting a healthy lifestyle it is critical for the prevention of high blood pressure and is an indispensable part of the treatment of those with hypertension. High levels of physical activity and greater fitness are associated with reduced incidence of hypertension. However until the beginning of the 1990 decade, the resisted exercise was not inclued at the internacionals statements for people with heart disease. Fortunately, in the past few years, this type of exercise started to take into account as a possible strategy for the first and second prevention of diferents cardiovascular diseases. The aim of this study it is to evaluate, through a systematic review, the contribution of the resisted exercise on the cardiovascular responses in hypertensive male adults. Twenty eight articles were pre-selected for this study, four attend to the requirements. The results were not consistent in this review, only the diastolic blood pressure demonstrated decrease in three of the four studies, in circuit protocol as much as in the conventional protocol. Otherwise one study proved an increase in the VO2max, wich is an important data, because it is an anaerobic exercise and, an improve was not expected. An other article analised the harm issues of the Valsalva manouvre, where it was presented the maximum blood pressure values (345/245 mmHg) and evidences of lower blood pressure rises in the intra-arterial, intrathoracic and intra-abdominal pressures when the exercise was performed without the manouvre, enhancing the necessity to avoid the use of this manouvre in hypertensive individuals.

Análise dos métodos de cálculo de golpe de ariete em tubulações

This work studies the most commonly used methods and make comparisons and discussions of the findings made by each of them and the results provided by them. The objective of this research was to show that the method of characteristics is currently the most efficient method to perform these simulations because of its broad scope low simplifications, requirement allowing to consider every detail of the pipe and fluid. Manual calculations are performed and also a software capable of calculating this phenomenon for various situations, such as water pump, elevated tanks, valves and quick maneuver was developed. The software is based on the method of characteristics that is currently recommended by ABNT. These methods, and the results are obtained numerically and graphically are adopted pipes and amount of downstream conditions and in which will be applied. The conclusions reached showed that the Allievi method is widely used yet because of its efficiency and quick calculation for simple pipes. The method of characteristics, although a lot of work to be calculated due to the calculation is iterative process and requires a program to use it, is the only one that allows the calculation with all amount to the conditions situations and downstream of all the pipe possibilities found

Influência do gênero na demanda visual por mapas em escalas diferentes em sistema de navegação e guia de rota

This work investigates the gender effect on visual demand of drivers for dynamic maps at different cartographic scales presented In-Vehicle Route Guidance and Navigation System (RGNS). A group of 52 subjects (26 males and 26 females) took part in an experiment performed in a low-cost driving simulator. the driver's task consisted of navigating in an unknown route using a RGNS prototype which presents maps at two different cartographic scales. This paper replicates the known phenomenon of significant relationships between gender and performance at visual-spatial tasks issue. Our results show that drivers of different genders present distinct levels of visual demand both due to the cartographic scales and maneuver complexity variation. These discussed results are based upon individual differences in terms of spatial ability and spatial anxiety.

Processing optimized for symmetry in the problem of evasive maneuvers

The increasing number of space debris in operating regions around the earth constitutes a real threat to space missions. The goal of the research is to establish appropriate scientific-technological conditions to prevent the destruction and/or impracticability of spacecraft in imminent collision in these regions. A definitive solution to this problem has not yet been reached with the degree of precision that the dynamics of spatial objects (vehicle and debris) requires mainly due to the fact that collisions occur in chains and fragmentation of these objects in the space environment. This fact threatens the space missions on time and with no prospects for a solution in the near future. We present an optimization process in finding the initial conditions (CIC) to collisions, considering the symmetry of the distributions of maximum relative positions between spatial objects with respect to the spherical angles. For this, we used the equations of the dynamics on the Clohessy-Witshire, representing a limit of validation that is highly computationally costly. We simulate different maximum relative positions values of the corresponding initial conditions given in terms of spherical angles. Our results showed that there are symmetries that significantly reduce operating costs, such that the search of the CIC is advantageously carried out up to 4 times the initial processing routine. Knowledge of CIC allows the propulsion system operating vehicle implement evasive maneuvers before impending collisions with space debris.
