Objective: To describe cognitive functions and functional outcome in young patients with isolated infratentorial infarcts.Background: Contemporary knowledge implies a cerebellar contribution to cognitive behavior. Neuropsychological examination of patients with selective cerebellar lesions provides an opportunity to document the existence and nature of clinically relevant cognitive manifestations from lesions of the cerebellum.Methods: Prospective case series. The patients were assessed acutely and at 4 and 12 months after onset. Twenty-four patients from a consecutive series of 105 patients aged 18 to 44 years with cerebral infarction had a brain stem or cerebellar infarction. Fourteen age-matched controls were used for neuropsychological comparisons. Evaluation included MRI, angiography, and transesophageal echocardiography. Disability and neurologic dysfunction were assessed by the modified Rankin scale, NIH stroke scale, and maximal working capacity. A comprehensive neuropsychological battery was performed at baseline in 20 of the 24 patients.Results: Eighteen patients had a cerebellar infarct. Two patients had lateral medullary infarcts, and two isolated pontine infarcts. Twenty-two patients had a favorable outcome according to the modified Rankin scale (grade 0-2) and the NIH scale. In contrast, 12 patients were granted full or partial sick leave at the 4 months follow-up, and 10 patients at 12 months. Patients generally performed worse than controls in various aspects of cognitive function, especially in tasks concerning working memory, the temporary storage of complex information, and cognitive flexibility. Measures of verbal IQ (r = -0.74) and performance IQ (r = -0.78) were related to the size of the infarct. The block design task performance in the early poststroke period predicted maximal working capacity at 12 months.Conclusions: Cerebellar damage impairs central aspects of attention and visuospatial skills. In contrast, intelligence and episodic memory remain unchanged. When the lesion involves large portions of the cerebellar hemispheres, changes concerning broad areas of intelligence may occur. The prognosis is favorable for neurologic dysfunction, but cognitive deficits may prevent return to work.

The article is devoted to the study of functional status dynamics (working capacity, stress) of oil and gas workers of various professional groups during the shift period in Arctic conditions. The survey involved 70 specialists from oil and gas producing companies working on a shift basis in the Nenets Autonomous District of five professional groups: operators for oil and gas production, operators of the boiler and treatment facilities, drivers, engineers and maintenance technicians. The research methods are studying documentation, monitoring the work process, questioning, psycho-physiological and psychological testing, statistical methods of data analysis. The study of the functional status was carried out with the help of biochemical (analysis of saliva on cortisol), psychophysiological (complex visual-motor response) and psychological (questionnaire: “Feeling. Activity. Mood.” by V.A. Doskin and co-authors; the test of color preferences of M. Lusher in adaptation L.N. Sobchik) methods. As a result of the study, By the end of the shift period the statistically significant increase was revealed in the stressful status of the operators of the boiler and treatment facilities, maintenance workers and drivers. According to the dynamics of the functional status, one can observe a decrease in the working capacity of all specialists by the end of the shift period. The specialists, working in the open air (drivers and engineers), had more negative dynamics of functional status in comparison with other professional groups. These workers can be referred to the risk group.

1. There is evidence that opioid peptides influence blood pressure and heart rate in animals and man. In the present investigation the effect of naloxone on the exercise-induced increase in blood pressure, heart rate, plasma catecholamines, plasma renin activity (PRA) and plasma aldosterone was investigated in nine healthy men. A submaximal work test was performed on two occasions. The test consisted of ergometer bicycling for 10 min on 50% of maximal working capacity immediately followed by 10 min on 80% of maximal working capacity. Ten minutes before exercise the subjects received in a randomized manner a bolus dose of naloxone (10 μg/kg) or a corresponding volume of saline followed by a slow infusion (15 ml/h) of naloxone (5 μ h−1 kg−1) or saline, respectively. 2. After exercise systolic blood pressure, heart rate, plasma catecholamines, PRA and plasma aldosterone increased during both saline and naloxone infusion. The changes were similar in both studies. 3. Accordingly, opiate receptors sensitive to naloxone in a moderate dosage seem not to be involved in the cardiovascular response and the increase in plasma catecholamines, PRA and plasma aldosterone induced by exercise.
