[Cognitive impairment and compliance in chronic heart failure]. / Kognitivnye narusheniia i priverzhennost' lecheniiu u patsientov s khronicheskoi serdechnoi nedostatochnost'iu.

AIM: To determine the factors of cognitive impairment and non-compliance in patients with chronic heart failure (CHF). MATERIAL AND METHODS: One hundred and fifty-seven patients with CHF and 32 patients without chronic heart failure (controls) were examined. Neuropsychological assessment using a 30-minutes protocol recommended by NINDS-Canadian Stroke Standards (NINDS CSS), magnetic resonance imaging, cognitive ERP and a test of compliance were used. RESULTS AND CONCLUSION: Approximately 62% of patients did not perform medical prescriptions. Non-compliance was associated with an increase in the severity of subcortical and perivenricular leukoaraiosis, a slowdown in decision-making processes (an increase in the P300 latency), worse performance on speech activity tests, optical/spatial and frontal dysfunctions and memory. Patients with non-compliance had frontal cognitive impairment (58%), memory impairment (40%) and mixed forms (21%). Cognitive impairment in patients with chronic heart failure was associated with the lower left ventricular ejection fraction and deterioration in indices of diastolic function.

[Forecasting model of transfer of 137Cs to the plants].

The forecasting model of the concentration ratio (CR) of 137Cs in the plants taking into consideration organic carbon, pH, mobile and total content of potassium in soil has been developed on the basis of the radioecological investigations in the valleys of the Resseta and Vytebet rivers. The type of functional dependence of CR from soil characteristics can be used for an estimation of the content of radionuclides in various species and productive parts of plants.
