Summary:

Objective: to analyze the prevalence of digestive diseases during social stress among the population of different age groups (young, mature, elderly / old). Material and Methods. We studied data from the official statistical reports of the health Committee of the city of Saratov and the logs of incoming and departures / deaths of patients in the surgical and gastroenterology clinics of the city for 1990-2006. Social stress was considered as a factor in the breeding population system from the equilibrium state. Linear regression analysis, odds ratio, and analysis of the speed characteristics of the dynamics of the studied parameters in time were applied. The number of time moments when the sign of the rate of change in the prevalence of the studied parameters changed to the opposite was estimated. Results. The change in the sign of the rate of prevalence of acute pathology of the digestive system was most often observed during the period of maximum severity of social stress, which emphasizes the importance of the social component in the emergence and development of digestive pathology. The increase in the prevalence of diseases of the digestive system in all age groups was revealed. The increase in the prevalence of individual nosological forms, as well as the greatest number of times when the sign of the rate of prevalence of the pathology changed to the opposite, were most often registered among the population of young and elderly / senile age. The population of the mature age was characterized by greater stability of the studied parameters, that is, higher resistance to social stress. Conclusion. The prevalence of diseases of the digestive system during the period of social stress varied among the population of different age groups asynchronously: the most significant changes in the studied parameters were observed among the population of two extreme age groups: young and elderly / old people. These groups of people need closer attention of the doctor than patients of mature age, because they have a higher risk of developing diseases of the digestive system.

Comparative evaluation of autonomic regulation of circulation in patients undergone coronary artery bypass grafting or correction of acquired valvular heart disease

Summary:

The aim of the research was to study the peculiarities of vegetative regulation of blood circulation in cardiac surgery patients who underwent coronary artery bypass grafting (CABG) or correction of acquired valvular heart disease (CAVHD). Material and Methods. In this study we included 42 patients (12 women; 63 (57; 67) years), who underwent CABG, and 36 patients (16 women; 58 (47; 65) years) who underwent CAVHD. The synchronous 15 minutes records of electrocardiogram and photoplethysmogram (PPG) were performed in all patients before and after surgery. Time domain and frequency domain measures of heart rate variability (HRV) and index of synchronization between low-frequency (LF) oscillations in HRV and PPG (index S) were analyzed. Results. Most studied autonomic indices did not have statistically significant differences between patients with CABG and CAVHD in the study stages, except for heart rate, which was higher in patients before CAVHD (p=0,013). Conclusion. The values of HRV and index S do not depend on the difference in the clinical status and the features of performed cardiac surgical interventions between patients with CABG and CAVHD.

Platelet indices as markers of platelet turnover and aggregation: pathophysiological interpretation, clinical impact, perspectives in research

Summary:

The purpose of the review is to characterize existing in open access bibliographical databases such as eLibrary and PubMed evidence on clinical impact of morphometric platelet indices as markers of platelet aggregation ability and turnover as a methodology and theoretical framework of further investigation. Studies results were pooled from open access bibliographic databases (eLibrary, and PubMed) according to modified PRISMA algorithm. Relevant studies were identified by systematic searches of the original studies published during the last 10 years in the Russian and English languages. Results of 96 original studies in accordance with inclusion criteria were published during the last 10 years in scientific journals indexed in eLibrary, and PubMed. The majority of publications (64.58%) consist of evidence pro diagnostic and prognostic significance of platelet indices. Studies demonstrating the significance of platelet indices as possible risk markers of thrombotic events in cardiovascular patients were predominating among "pro" publications. In 15.63% published results contradict concept of platelet indices usefulness as diagnostic and prognostic markers in clinical practice. Morphometric platelet indices can be considered as useful diagnostic and prognostic markers of thrombotic events in cardiovascular patients. Existing gaps in evidence suggest the need of further investigations.
