[Parametres of cardiopulmonary exercise testing in patients with lung and esophagus cancer according to their gender and age.].

Cardiopulmonary exercise testing is a diagnostic method, which can be used for oncological patients. It shows its perspectives in measuring reserve capacity of the human organism, determining the risk of postoperative complications, and long-term prognosis. The method is also useful for optimization of rehabilitation measures, which is actual for polymorbid aged patients.

[OLD AND NEW PROBLEMS IN THE TRAINING OF ANAESTHESIOLOGISTS].

In connection with the upcoming changes in the professional education in Russia, there is a need to adapt the existing system of training of anesthesiologists. We sent questionnaires to 831 anesthesiologists to identify their opinion about the planned transition to continuous medical education. We found that the majority of respondents do not object to the implementation in practice of this system, especially if the educational model will be adapted to the specific requests of practitioners.

[Enterovirus infection as a risk factor of acute coronary syndrome and its complications].

Antigens of enteroviruses were detected quantitatively in the modified complement-binding reaction in blood samples from 102 of the 208 (49%) patients with ACS, in coronary artery tissues from 23 of 24 and heart from 51 of 94 (54.3%) patients with MI who died from cardiogenic shock and/or cardiac rupture. The relative level of enterovirus antigen (RLEVA) in the blood of patients with MI complicated and uncomplicated by cardiogenic shock and/or cardiac rupture was 0.

[Role of insulin and its antagonists in the pathogenesis of diabetes mellitus and its complications].

The content of insulin antagonists (growth hormone, cortisol, catecholamine, DOPA, free fatty acids) was studied in 40 women suffering from diabetes mellitus, including 12 insulin-sensitive and 15 insulin-resistant, and 13 women with freshly diagnosed untreated diabetes. The greatest content of all the insulin antagonists was revealed in the insulin-sensitive patients during the decompensation period. It is assumed that in this period, diabetogenic actions of insulin antagonists create the most favourable conditions for the formation of insulin antagonists create the most favourable conditions for the formation of insulin resistance; this resistance is then maintained by the increased antibody titre due to the elevation of therapeutic insulin doses and lengthy persistence of the high growth hormone level in the insulin-resistant patients.
