Зависимость эхокардиографических показателей от возраста и продолжительности занятий спортом
The influence of training load on the cardiovascular system of athletes of all ages and the duration of time. When comparing the athletes who train up to two years increased the size of the right ventricular performance, ejection fraction. Also observed lower values in fractional shortening. For the first 4-5 years of performance of the cardiovascular system of athletes of all ages characterize the economisation of the heart. Characteristics of echocardiographic parameters in athletes with little experience of employment indicates the influence of sports on the cardiovascular system. Noted changes can be described to a certain extent not only morphological changes, but also functional. It is established that the character of cardiac remodeling determined by the level of physical and functional training athletes of all ages and fitness facilities, the state of their health, as well as the intensity of training and competitive pressures.
In the internal medicine wide spectrum the gastroenterology is one of the chapters, less enlightened by the scientific evidence. It does not mean that the practice of the grasntroenterology may ot be improved by the systematic use of the approaches of the evidence based medicine
A general algorithm for the decomposition of differences between two values of an aggregate demographic measure of age and other dimensions is realized as Excel/VBA. It assumes that the aggregate measure is computed from similar matrices of discrete demographic data for two populations under comparison. The algorithm estimates the effects of replacement for each elementary cell of one matrix by the respective cell of another matrix. The replacement runs from young to old ages.
This prototype development explains the challenges encountered during the ISO/IEEE 11073 standard implementation process. The complexity of the standard and the consequent heavy requirements, which have not encouraged software engineers to adopt the standard. The developing complexity evaluation drives us to propose two possible implementation strategies that cover almost all possible use cases and eases handling the standard by non-expert users. The first one is focused on medical devices (MD) and proposes a low-memory and low-processor usage technique. It is based on message patterns that allow simple functions to generate ISO/IEEE 11073 messages and to process them easily. MD act as X73 agent. Second one is focused on more powerful device X73 manager, which do not have the MDs' memory and processor usage constraints. The protocol between Agent and Manager is point-to-point and we can distribute the functionality between devices.
Developed both implementation X73 Agent and Manager will cut developing time for applications based on ISO/EEE 11073.
