Dear colleagues,

Abstract

Our regular readers and authors are aware that our editorial team does not encourage review publications. The reason is obvious: as a rule, such reviews of literature are excerpts of theses, and they pursue an objective of getting another contribution, which serves for practical purposes and is a far cry from science. Even though the majority of main problems in surgery have longstanding protocols (recommendations) that are updated and reissued each 2–3 years both at the international and national level. For all that, we do publish analytical reviews for a number of fundamental medical problems if they contain rare information and analysis of major problems concerning our occupation. An example of such publication is the article by American authors David Cooper and Aziz Salim, which is about recent advances and hurdles yet to pass for cardiac xenotransplantation: there is a long distance to take before such material is approved in the protocols. In this issue, we would like you to pay attention to the article by Abram L. Syrkin and Evgeniya A. Kogan, which analyzes ideas about the nature of cardiac ageing followed by a developing decrease in the majority of physiological functions. Such information is extremely important because the number of patients at surgical hospitals with an increased fragility of their bodies is on the rise.

Anyway, other publications in the present issue of our journal are extremely interesting too. Enjoy reading,

Editor-in-Chief Sergey Dzemeshkevich
