Pain and dyspepsia in patients with affective disorders appeared to be constant and more intense than in the patients without concomitant anxious depression. Psychophysiologic tests in 83% of patients with comorbid conditions revealed significant psychomotor dullness manifested in reliable lower speed of visual motor reactions. Pharmacologic correction via anxiolytics (Adaptol, Afobasol) combined with standard therapy for chronic pancreatitis exacerbation enabled to improve clinical symptoms, but Adaptol appeared to slow simple visual motor reactions, therefore has to be ruled out in engine operators. Pharmacotherapy of chronic pancreatitis, that included Afobasol in addition to standard treatment, promoted reliable improvement of occupationally important psychophysiologic functions. This study received a patent.

Ability to railway locomotive operation is determined via suitability criteria of occupationally important qualities of operator and operator's assistant, and of nervous system functional state. Lower reliability manifested in worse functional state of engine operator or in lost occupationally important qualities can be connected with various diseases of which most prevalent are cardiovascular disorders. Transitory brain circulatory disorders can cause cognitive disturbances varying in severity. When mild cognitive disorders, precise diagnosis leads to effective prevention of the diseases development and preserved occupationally important qualities in engine operators. Neuropsychologic methods for mild cognitive disorders help not only to diagnose presence and intensity of cognitive defect, but to suggest a mechanism of its development, that eventually increases efficiency of correction.

Analysis covered principles and legal norms, regulating human rights for security of health information, and causes of anxiety about workers' discrimination due to genetic test results. The authors necessitate differentiation between discrimination and reasonable restrictions favorable for workers in cases when work conditions can be a health hazard for person due to genetic predisposition.

Relaxation sessions appeared to cause better mood, lower blood pressure, increased reactions speed, reduced number of errors. Purposeful training of the specialists in self-regulation is extremely important for preparation to work activity and for prophylactic and social measures aimed to preserve and improve health in locomotive crew workers.

The authors analyzed present standards of occupational fitness in workers performing critically important operating activities and methods of occupational selection with possible obstructive sleep apnea syndrome. I stage recommendations are suggested in diagnosis of obstructive sleep apnea syndrome in workers engaged into railway safety. Obstructive sleep apnea syndrome appeared to threaten operators' activity, to cause accidents, to early disablement due to life-threatening complications, to unsuitability for the occupation due to diseases connected with obstructive sleep apnea syndrome (arterial hypertension, diabetes mellitus, metabolic syndrome, cardiac rhythm and conductivity disorders, obesity).

Analysis covered biomarkers that form allostatic load index, and their ratio for variable allostatic load index levels. Moderate allostatic load appeared to prevail in the examinees group. Findings are that systolic and diastolic blood pressure, general cholesterol and hemoglobin make major contribution into allostatic load index. Comparison covered models of allostatic load index calculation for variable biomarkers sets.

Examination covered 158 railway workers underwent complete endovascular revascularization of myocardium for coronary stenosis; all of them had ventricular arrhythmias before coronary surgery. Findings are that in long-term period (in 16 months in average) after coronary stenting, grade I and III ventricular extrasystoles disappeared in 77.8 and 54.5% of cases respectively, but only in 11.9% of grade IV ventricular extrasystoles cases. Ventricular extrasystoles remained unchanged in 44.3% of cases. Reliable relationships were seen between unchanged grade IV ventricular extrasystoles and body weight index (OR = 5.49, 95% CI: 0.87-34.67), general cholesterol level (OR = 1.69; 95% CI: 1.06-2.69), low density lipoproteins (OR = 1.66; 95% CI: 1.00-2.76) and left ventricular ejection function lower 45% (OR = 1.61; 95% CI: 1.14-2.27), exertion ventricular extrasystoles before myocardium revascularization (OR = 3.1; 95% CI: 1.78-5.41). That necessitates correction of the mentioned risk factors of cardiac arrhythmias for restored work capacity.

Currently, there is not a treatment that provide a cure of sensorineural hearing loss. Regular, individually tailored treatment should be directed to the pathogenic mechanisms and specific clinical symptoms of hearing loss, as well as the prevention of complications. We recommend using non-drug therapies that can improve blood flow in labyrinth, tissue and cellular metabolism.

For biomonitoring in workers exposed to pesticides, the authors designed a method detecting low levels of Imidacloprid in urine of operators, based on tandem liquid mass-spectrometry with ionization source--electrostatic dispersion (positive ionization) in multi-reaction monitoring regime with subsidiary ion (mass/charge) 209 for quantitative assessment and ion 175.1 for confirmation onion ratio. The study incorporated diurnal urine, about 100 ml of average sample was frozen and kept at temperature -20C for analysis. Before extraction, the sample was unfrozen, an aliquot of 5 ml was selected, diluted with 5 ml of 0.1% formic acid. The substance was concentrated out of the urine samples via solid-phase extraction with application of cartridges based on octadecylsilane, eluition--1 ml of methanol. Lower limit of Imidacloprid detection in urine is 0.02 ng/ml, of the quantitative assessment--0.1 ng/ ml, linear range of concentrations measured 0.1-10 ng/ml. The method was tested for monitoring in workers exposed to Imidacloprid preparations in natural conditions of pesticides application in agriculture, with various processing technologies. Imidacloprid was identified in urine of two professional operators after work in seed treatment and the subsequent seeding at lower limit of detection (0.02 ng/ml) and 0.34 ng/ml.

The group 1 used standard vibroinstrument, the group 2--pneumoinstruments with low vibration velocity parameters. Triple study during the working shift revealed in group 2 an adequate reaction of vegetative nervous system to vibration, in group 1 a negative trend was seen with centralization of regulatory processes and absence of adequate recovery in an hour after work.
