A six-year prospective study of 3775 individuals, first examined in 1978, using an original mathematical program of myocardial infarction risk prognosis, is reported. The program is based on an integral assessment of 19 risk factors, each having 4 degrees of severity. The subjects were allocated to one of 3 groups, depending on the prognostic risk score. In the low coronary risk group (2068 people), there was 1 (0.048%) myocardial infarction over 6 years. There were 12 (0.76%) infarctions in the medium risk group (1569 people), and 62 (44.92%) infarctions in the high risk group (138 people). Therefore, the program is capable of identifying a limited (about 4%) population that is going to develop 80% of all myocardial infarctions within the next 5 or 6 years.
Health effects as a result of the accident at the Chernobyl nuclear power plant occurred in 1986 are considered in the paper. Wrong prognosis of the health effects with respect to mortality and morbidity among the population exposed to low radiation doses is shown. Proven increase in thyroid cancer cases among people who were children aged from 0 to 18 at the time of the accident is shown. Linear relationship between thyroid cancer cases and dose to thyroid ranged from 0.2 to 4.0 Gy is considered. An additional absolute risk of thyroid cancer in children varies in the range 1.9-2.6 cases per 10(4) person-year Gy. During the fifteen years following the accident no cases of acute and chronic radiation sickness have been revealed because the population living in contaminated areas received low radiation doses. Also, exposures to low radiation doses did not result in excess of malignant tumors among population. In some cases the outcomes of acute radiation sickness were as follows: radiation damages to the skin, cancer cataracts, development of oncopathology.
An analysis of results of treatment of 212 patients with peritonitis of different etiology allowed the author to establish main factors (clinical and laboratory), responsible for the level of lethality. A scheme of assessment of the outcome of the disease is proposed. It has advantages over the Mannheim Peritonitis Index.
The authors evaluate relationships of parameters describing activities of Health center and selected according to "discrete correlation galaxies" method with characteristics of health state of population covered by the center. The article contains mathematic models that could be a basis for forecasting changes of health state characteristics under variation of Health center activity parameters.
Activity of polymorphic N-acetyl transferase characterized by bimodality (fast and slow acetylators) in normal subjects was studied in 150 epileptic patients. The epileptic versus normal subjects had a significant predominance of slow acetylators. The data obtained suggest that slow acetylation is one of the possible factors predisposing to epilepsy and responsible for a more severe course of the disease. The results of the study suggest that determination of the activity of polymorphic N-acetyl transferase may serve as a prognostic criterion of epilepsy.
Aim of the study was assessment of efficacy of rendering urgent aid to patients with acute coronary syndrome (ACS) at prehospital stage on the territory of Khanty-Mansi Autonomous Okrug (KhMAO). The analysis showed that yearly about 5000 inhabitants of KhMAO-Yugra received prehospital medical care (30% because of acute myocardial infarction, 70% because of unstable angina). Over 3 years portion of persons requesting medical aid during first 3 hours after onset of pain attack increased 6.1%. Rate of prehospital fibrinolysis did not exceed 6.5%. Alteplase was used most often (79.7%). Late patient's appeal was among causes of rare application of thrombolytic therapy (41.8%). Most physicians responsible for prehospital care considered it necessary to refer patients with ACS directly to centers of interventional cardiology. The data obtained would promote improvement of quality of medical aid to ACS patients at prehospital stage.
To measure blood IL-6, IL-10, creatinine levels, calcium, sodium and potassium in blood and saliva, melatonin in urine of patients with acute coronary syndrome without ST segment elevation for the prediction of the clinical course at the post-hospital stage.
The study included 93 patients with complicated (n = 46) and uncomplicated (n = 47) coronary syndrome without ST segment elevation. Blood IL-6, IL-1, creatinine levels, calcium, sodium and potassium in blood and saliva, melatoni n in urine were determined on days 1-3 after hospitalization. 6-hydroxymelatonin was measured by HPLC in urine collected between 23 p.m. and 8 a.m., melatonin i in urine collected between 8 a.m. and 23 p.m.
Complicated coronary syndrome was associated with increased levels of melatonin (night), blood IL-10 and Na, salivary, Na and Ca while the uncomplicated condition with increased blood melatonin (daytime), IL-6, creatinine, Ca, Na, K, and salivary K. 90 patients were followed up within 12 months after discharge. End-points developed in 36 (40%) of them. Logistic analysis yielded variables and 2 logistic regression equations The data on night melatonin +5 and +4 were included in ROC analysis. The night melatonin +5 values over 0.7453 were associated with increased risk of complications in the post-hospital period (6 months) and values of 0.7453 or lower with the enhanced probability of uncomplicated clinical course. Prognostic sensitivity was estimated at 90%, specificity at -54.39%. The night melatonin +4 values over 0.2903 were associated with increased risk of complications in the post-hospital period (12 months) and values of 0.2903 or lower with the enhanced probability of uncomplicated clinical course. Prognostic sensitivity was estimated at 77.8%, specificity at -59.26%.
The night melatonin +5 and +4 models can be used to predict the clinical course of acute coronary syndrome during 6 and 12 months of the post-hospitalization period.
to estimate the frequency and severity of acute kidney injury (AKI) in patients with stroke and the influence of AKI on intra-hospital lethality.
180 patients with stroke. 8 (4.4%) of them died within 24 hr after admission. It was impossible to diagnose AKI in these patients from serum creatinine dynamics. The development of AKI was followed up in the remaining 80 (47.1%) men and 91 (52.9%) women (mean age 66.6 ± 11.2 yr). AKI was diagnosed and classified as recommended by KDIGO (2012).
AKI was documented in 47 (27.3%) patients including 13 (41.9%) and 34 (24.1%) with hemorrhagic and ischemic stroke respectively. Logistic regressive analysis revealed association of in-hospital lethality with AKI (relative risk 2.5; 95%, CI 1.7-3.8) regardless of sex, age, stroke type, duration of the disease prior to hospitalisation, arterial hypertension, and diabetes.
stroke is complicated by AKI in every fourth patient; in combination, they significantly increase intra-hospital lethality.
A dynamic prognostication scheme was elaborated with respect to a potential demographic situation among the adult population on the basis of a study of prevalence of severe surgical diseases of the abdominal cavity. It makes it possible to plan a further surgical-service promotion, to forecast potential complications and to define measures of how to cut the number of such complications.
to study the influence of the patients adherence to the recommended therapy after coronary artery bypass grafting (CABG) on prognosis of postoperative period.
We examined 197 consecutive patients with stable coronary artery disease (CAD) who had undergone CABG. Age of patients was 38-75 years.
Assessment of modifiable cardiovascular risk factors showed that about half of patients had smoked before CABG and only a few gave up smoking after surgery. Number of patients with abdominal obesity increased by 8% after surgery. Number of patients involved in physical trainings remained unchanged. Adherence to drug therapy before CABG was low. Less than half of the patients took antiplatelet agents, beta-blockers, angiotensin-converting enzyme inhibitors, only 25% took statins. One year after CABG number of patients taking appropriate medications significantly increased. However, only half of patients managed to achieve the main objectives of secondary prevention.
