BACKGROUND: Тhe main tasks of medical and psychological rehabilitation (MPR): accelerated restoration of the functional state and working capacity of military personnel; increase of reserve capabilities; reduction of the influence of risk factors for various diseases; secondary prevention of chronic diseases and prevention of chronization of acute processes; carrying out measures to eliminate and reduce psychopathological syndromes in order to achieve mental adaptation; restoration of professional health, correction of maladaptosis. AIMS: Is to study the informative value of variational cardiointervalometry (VCM) indicators in assessing the effectiveness of MPR of military personnel. MATERIAL AND METHODS: This study was conducted in the branch Clinical Sanatorium Volga of the Federal State Budgetary Institution Privolzhsky of the Ministry of Defense of the Russian Federation during the work of the psychotherapy room with the category of MPR for 12 months. In addition to the regulated volume of diagnostic studies, the Device for psychophysiological testing UPFT-1/30 Psychophysiologist (manufacturer of LLC NPKF Medikom MTD, Russia) was used. One of the research methods is the assessment of the functional state of the heart rhythm by the method of variational cardiointervalometry (VCM) at admission to MPR and before discharge (also referred to in the literature as heart rate variability, HRV). The study was conducted with 116 servicemen undergoing MPR for fatigue of 12 degrees for 10 days. Representatives of the Strategic Missile Forces (RVSN) ― 34 people; aerospace forces (VKS) ― 32 people; ground forces (SV) ― 50 people. The data is processed in StatSoft Statistica 10 Russian Portable 10.0.1011.0 x86. RESULTS: The average values for the entire group (116 servicemen): at admission and before discharge IN (stress index) increased statistically significantly from 284.5 to 359.7 cu; VLF-decreased from 21.1% to 16.0%; LF/HF (vagosympathetic interaction index) ― from 2.7 to 4.0 cu; Centralization index ― from 3.8 to 5.1 cu; PARS (indicator of adaptation of regulatory systems) ― from 4.6 to 5.3 cu. The result is a pronounced tension of regulatory systems, active mobilization of protective mechanisms, increased activity of the sympatho-adrenal system and the pituitary-adrenal system. CONCLUSION: VCM (HRV) is one of the practical informative methods. RVSN: an increase in the voltage of regulatory systems as a reaction to physical exertion, a post-loading energy-deficient state, the index of vagosympathetic interaction has shifted to the parameters of the norm.VCS: an increase in the voltage of regulatory systems, an increase in the activation of the sympathetic nervous system, an active mobilization of protective mechanisms. SV: a tendency to reduce the voltage of regulatory systems, a post-loading energy-deficient state, a balanced state of the autonomic nervous system (VNS). A delayed training effect is likely, changes occur in the late phases of recovery, after the end of the rehabilitation period.

The features of production factors established at the main workplaces of shoe production are considered. The materials on the results of the study of the functional state of the central nervous system of women workers of shoe production in the dynamics of the working day are presented. The level of functional state of the central nervous system was determined by the speed of visual and auditory-motor reactions, installed using the universal device chronoreflexometer. It was revealed that in the body of workers of shoe production there is an early development of inhibitory processes in the central nervous system, which is expressed in an increase in the number of errors when performing tasks on proofreading tables. It was found that the most pronounced shift s in auditory-motor responses were observed in professional groups, where higher levels of noise were registered in the workplace. The correlation analysis showed a close direct relationship between the growth of mistakes made in the market and the decrease in production. An increase in the time spent on the task indicates the occurrence and growth of production fatigue.Funding. The study had no funding.Conflict of interests.

Toxicity and hazard assessment of dioctyl terephthalate (DOTP) was performed in acute, subacute, and chronic experiments, and its principal toxicometry parameters were determined.It was found that on single exposure DOTP exhibits low toxicity and hazard. No resorptive and irritant effects on skin and mucous membrane of eyes were detected in animal experiments. The single inhalation exposure threshold limit value was set at 300 mg/m3, based on the results of monitoring of the functional state of the central nervous system and myocardium and hematological parameters.Thirty-day subacute experiments (oral administration, inhalation exposure, and skin applications) revealed no accumulation of the compound.Four-month chronic exposure to DOTP aerosols (concentration 96,8 mg/m3) caused disorder of the functional state of the central nervous system and myocardium, changes in the hematological and biochemical parameters, gas and acid-base status of the blood, and morphological changes in the lungs and heart. Embryotoxic, genotoxic and gonadotoxic effects were not detected.The chronic inhalation exposure threshold limit value for DOTP (Limch) was set at 18,6 mg/m3, and the concentration of 3,4 mg/m3 was found to be ineffective.The maximum allowable concentration of DOTP in the air of the working area was set at 3,0 mg/m3, hazard class 3.

Abstract Background A defecation reflex involves sensory information from the colon sent to the central nervous system which results in propulsive motor patterns in the colon through programmed neural activity from the autonomic nervous system. Neurological causes of constipation are recognized but specific neurological pathways that contribute to pathophysiology of the disease is underexplored. Diagnosis and treatment usually do not involve the autonomic nervous system. Aims Our objective was to assess autonomic dysfunction and abnormal defecation reflexes as a possible cause of chronic constipation. Methods Defecation reflexes were assessed by high-resolution colonic manometry through balloon distention, meal intake, and rectal bisacodyl. Specific heart rate variability (HRV) parameters were used to assess general orthostatic autonomic reactivity, and autonomic functioning during high resolution colonic manometry, in 14 patients with chronic refractory constipation considered for surgery. Results All patients had a unique combination of motility, reflex ability and HRV profiles. Patients overall did not generate HAPWs or had lower HAPW amplitude and lower propulsive activity compared to healthy individuals. Half of the 14 patients were tested to have high sympathetic tone based on Baevsky’s stress index prior to HRCM, and 11 of the patients had sympathetic hyper-reactivity and/or low parasympathetic reactivity to at least one type of colonic stimulation during HRCM. Abnormal autonomic tone or autonomic reactivity to colonic stimulation was present in all four patients with absence of the vagosacral defecation reflex. Five of the seven patients with absence of the sacral defecation reflex showed high sympathetic tone or high sympathetic reactivity to stimulation. Only two patients had abnormality in coloanal coordination and this was associated with low parasympathetic reactivity to stimulation in both patients. Conclusions The assumption that colonic resection was needed to remove an inert colon was wrong in most patients, but most patients had some form of reflex abnormality. Sympathetic dominance far outweighed parasympathetic dysfunction. Incorporation of assessments of defecation reflexes and autonomic nervous system activity into diagnosis of chronic refractory constipation provides a comprehensive pathophysiological understanding of specific defective neurological pathways contributing to dysmotility. This forms the basis for our individualized treatment efforts through sacral neuromodulation. Funding Agencies CIHR

The dominant position among the reasons of working-age population’s health deterioration belongs to diseases of the peripheral nervous system (PNS), the peak prevalence of which occurs at the age of 35–40. PNS diseases are diagnosed in about 76.0% of industrial workers, and account for more than half of all occupational diseases. They are the main cause of incapacitation and long-term disability. Publications on disability due to PNS diseases are isolated.The aim of the work. Clinical and functional characteristics of PNS disorders that cause disability in the working-age population.Material and methods. Among 91 496 first recognized as disabled in the Republic of Bashkortostan in 2014–2018, all disabled people of working age were selected due to PNS diseases, in which the main independent diagnosis was radiculopathy, polyneuropathy, neuropathy and vibratory disease with indication to lumbar-sacral radiculopathy with polyneuropathy of the upper extremities. 107 people were identified to constitute a closed cohort for a comprehensive study of the clinical-functional state and patterns of disability formation in them. The clinical-functional characteristic is given on the basis of the results of studies set forth in the directional medical documents and the assessment by an expert neurologist of the Main Bureau of Medical and Social Expertise. Statistical analysis was performed in Microsoft Excel.Results. The prevalence of PNS diseases has been found to be increasing. Three of the newly diagnosed neurological patients have been the carriers of PNS disease. PNS diseases are formed and reach peak in working age. Characterized by a chronic, progressive course, they often cause temporary and persistent disability. On average, there are 0.1 ± 0.028 persons with disabilities per 10 thousand of the able-bodied population due to PNS diseases, the level of which in dynamics for 2014–2018 increased by 1.7 times. Persons with disabilities (69.0%) are mainly represented by men, every second (50.6%) is over 50 years old, with an average age of 48.7 ± 5.7 years. The clinical-functional state is characterized by constant pain, numbness, seizures, restriction of movements in the limbs, sensory disorders, vegetative-vascular disorders.Conclusion. The quantitative evaluation of the main types of the body functions and main categories of vital activity persistent disorders made it possible to detect that 69.3 ± 4.4% persons with disabilities have persistent moderate abnormalities of functions in the range 40–60% (II degree), another 24.4 ± 3.8 — persistent pronounced abnormalities in the range 70–80% (III degree) and 6.3 ± 6.0% — persistent significant abnormalities in the range 90–100% (IV degree). The severity of impaired functioning of the body is the basis for the level of persistent disability determination.
