Emotional stress is associated with e.g. increased hormone release, high blood-sugar level and blood pressure. Stress clearly affects metabolism. Whether chronic stress exposure leads to altered urinary compositions with increased risk of CaOx; urolithiasis was examined by investigating the relation between stress burden and urine composition. 29 controls (CG), 29 CaOx stone formers (SF), and 28 patients with chronic inflammatory bowel diseases (CIBD) were advised to avoid unfavorable aliment. Any urolithiasis-related medications were stopped. At day 5, a 24-h urine was collected and comprehensive urinalysis performed. AP (CaOx) index was calculated. Subjects completed a questionnaire designed to measure perceived stress ("Trier-Inventory-of-Chronic-Stress"). Mean AP (CaOx) in CG, SF and CIBD amount to 0.8 (+/-0.3), 1.2 (+/-0.7), and 1.9 (+/-1.2), respectively. Increased AP (CaOx) in SF is mainly attributed to an increased effect of calcium and oxalate, whereas in CIBD this is additionally caused by a reduced effect of citrate, magnesium and volume. Stress dimensions are correlated to any investigated urinary parameter with an absolute value of r < or = 0.600; some correlations are statistically significant: whereas in SF only one combination, "lack of social recognition" versus calcium, shows significance, in CIBD various combinations are significantly related. In particular, sodium excretion increases with stress. In CG, some stress dimensions are directly related to citrate; with increasing stress, protection against CaOx crystallization tends to increase. It could be shown that stress load and urinary composition are related by statistical means. The observed metabolic stress response patterns in urinary compositions are different for the distinct groups, thereby, reflecting a conclusive picture. This is in particular in CIBD, for which a link between stress and inflammatory activity and between inflammatory activity and altered urinary composition is well established.

To study the structure of the risk factors and features of the course of a primary and recurrent myocardial infarction in elderly and old age we investigated 443 patients in the first 48 hours of the disease. Significant prevalence of risk factors was established in men with myocardial infarction in St. Petersburg. In most patients, especially with recurrent myocardial infarction, three or more risk factors were determined at the same time, which indicates a high coronary risk. The most frequently we observed the dislipoproteinemia, arterial hypertension, psycho-emotional stress, heart failure in anamnesis, link of disease to the season of year, the frequency of acute respiratory infections and colds, cardiac arrhythmia in anamnesis, smoking and alcohol abuse. Among the associated diseases, the cholelithic disease, urolithiasis and chronic bronchitis prevailed, especially with recurrent myocardial infarction. In the clinical pattern of disease in the first 24 hours, symptoms of heart failure prevailed. Anginal variant of a recurrent myocardial infarction occurs even less frequently, and symptoms of heart failure are more expressed, especially in prognostically unfavorable patients.

Chronic emotional stress is associated with increased cortisol release and metabolism disorders. However, few studies have evaluated the influence of chronic stress on calcium oxalate (CaOx) stone disease and its recurrence. A total of 128 patients were enrolled in this case-control study over a period of 20 months. All patients were CaOx stone formers with a recent stone episode (<3 months); 31 were first-time stone formers (FS) and 33 recurrent stone formers (RS). Dimensions of chronic stress were evaluated with self-reported validated questionnaires measuring stressful life events, perceived stress, anxiety, depression, burnout and satisfaction with life. An ad hoc self-reporting questionnaire was designed to evaluate stress-related specifically to stone episodes. Blood and urine samples were collected to determine cortisol levels and urinary composition. In addition, epidemiological data, socioeconomic information, diet and incidences of metabolic syndrome (MS) were reported. Overall, no significant differences were observed in the scores of cases and controls on any of the questionnaires dealing with stress. The number (p < 0.001) and the intensity (p < 0.001) of perceived stressful life events were higher in RS than in FS, but there were no differences between the two groups in other dimensions of stress. RS had higher glucose (p = 0.08), uric acid (p = 0.02), blood cortisol (p = 0.01), and urine calcium levels (p = 0.01) than FS. RS also had lower economic levels (p = 0.02) and more frequent incidences of MS (p = 0.07) than FS. Although no differences were observed in cases and controls among any dimension of chronic stress, the number and intensity of stressful life events were higher in RS than in FS. These differences correlate with variations in blood and urinary levels and with metabolic disorders, indicating an association between chronic stress and risk of recurrent CaOx stone formation.
