[Hyperbaric oxygenation in outpatient rehabilitation of COVID-19 convalescents]. / Primenenie giperbaricheskoi oksigenatsii v ambulatornoi reabilitatsii patsientov, perenesshikh COVID-19.

Searching for drug and non-drug modalities for the rehabilitation of patients with the post-COVID syndrome is an urgent public health challenge during the COVID-19 pandemic. Hyperbaric oxygenation is a promising method as a part of complex rehabilitation after COVID-19 due to its antihypoxic, anti-inflammatory, antioxidant and anticoagulant effects. OBJECTIVE: To study the effect of hyperbaric oxygenation as a part of comprehensive outpatient rehabilitation on clinical and functional parameters in COVID-19 convalescents. MATERIAL AND METHODS: The effect of hyperbaric oxygenation on clinical and functional parameters of 45 COVID-19 convalescents was studied: 22 males and 23 females aged 40-60 years. Patients were divided into three groups of 15 subjects each, depending on the CT stage of COVID-associated pneumonia (CT-0, CT-1, and CT-2-3). RESULTS: Patients in group 3 (CT-2-3) were on average in the older age group, had a higher body weight and a higher percentage of fat mass according to bioimpedance measurements, compared to the other groups. Most clinical-functional and laboratory parameters in this group were within normal or subnormal ranges. In addition, high cholesterol levels (total cholesterol 6.5±1.2 mmol/L) and subnormal levels of C-reactive protein (9.3 mg/L) were noted in group 3 patients. After comprehensive rehabilitation, an increase in the distance walked in the 6-minute walking test with a significant trend in the CT-0 (467.9±37.7→531.5±44.3 m; p<0.01) and CT-1 (533.9±74.3→570.1±57.8 m; p<0.05) groups was observed. A significant decrease in norepinephrine level in the group of COVID-19 convalescents with CT-2-3 (Δ 13%), and a decrease in glutathione peroxidase in all three groups (6465.0±1637.3→5101.0±1353.3, 6587.8±1919.3→5418.1±1289.7, 7699.5±1747.9→6620.1±1702.1 units/L in groups 1, 2 and 3, respectively; p<0.05) were recorded. CONCLUSION: The use of hyperbaric oxygenation in comprehensive outpatient rehabilitation of COVID-19 convalescents was associated with benefits, given the improvement of functional parameters, laboratory signs of limiting low-grade inflammation, sympathoadrenal activity, and oxidative stress.

[The influence of procaine electrophoresis and mesotherapy on the indices of body components and biochemical characteristics in the subjects above 30 years of age].

This study has demonstrated the effectiveness of a 2% procaine solution given with a view to improving metabolic parameters of aging, such as the body weight and composition along with the lipid profile in the patients varying in age from 30 years to 75 years. The study involved 95 patients treated with a 2% procaine solution that was administered by different methods (electrophoresis and mesotherapy) into several points of the collar region and upper back. The control group was comprised of the patients who received placebo by means of galvanization and mesotherapy. The results of the study indicate that the introduction of a 2% procaine solution in the treatment of metabolic disorders effectively improves selected metabolic characteristics of ageing and thereby helps to reduce the biological age in comparison with the control patients treated with placebo.

[The influence of different massage techniques on the characteristics of biological age in the subjects above the age of 30 years].

This paper is designed to demonstrate the efficacy of different massage modalities used to decrease the biological age in relatively healthy subjects between 30 and 69 years of life. The study involved 78 subjects (67 women and 11 men). Each of them underwent a course of 10 sessions of massage of the collar and upper back regions for the prevention of premature ageing and the reduction of the biological age. Cryomassage was performed with the use of cryocare packs and vacuum massage on the Cerri apparatus (Italy). The control group was comprised of the subjects given no treatment. The main characteristics measured before and after therapy included biomarkers of ageing and biological age. The results of the study indicate that both cryogenic and vacuum massage effectively improves certain biomarkers of ageing; namely, such treatment reduces systolic, diastolic, and pulse pressure, increase pulmonary vital capacity and breath holding time in expiration, improves the sense of equilibrium, self-assessment of health condition, and concentration of attention. Taken together, these effects contribute to the reduction of the biological age of the subjects and prevent their premature ageing to a greater extent than in the untreated persons.

[The influence of procaine electrophoresis and mesotherapy on the characteristics of biological age].

The assessment of the biological age is needed to estimate the level of health and the efficacy of measures being undertaken to slow down the ageing processes and prolong the active life of the patients. Earlier studies have demonstrated the improvement of both physical health and psychic status of the elderly patients following intravenous administration of procaine. The objective of the present work was to evaluate effect of various methods of administration of a 2% procaine solution on the biological age. A total of 95 subjects at the age between 30 and 75 years were enrolled in the study. The procaine solutions were applied to the collar region. The patients of group 1 were treated with 2% procaine electrophoresis, those in group 2 with procaine galvanization with the same parameters. Mesotherapy using the 2% procaine solution was given to the patients of group 3. It was substituted by placebo (0.9% physiological solution) in the patients of group 4 (controls). The study revealed the most significant decrease of the biological age (calculated as described by L. M. Belozerova) in the patients treated with procaine electrophoresis (91% improvement). The mesotherapeutic administration of procaine also produced the beneficial effect (59% improvement). Neither procaine galvanization nor placebo mesotherapy caused any significant change of the variables characterizing the biological age.

[The application of a pulsed low-frequency electrostatic field for the prevention of premature ageing].

This paper demonstrates the effectiveness of the application of a pulsed low-frequency electrostatic field (PLFESF) in order to prevent premature ageing. The study involved 50 subjects. PLFESF therapy was conducted using the DEEP OSCILLATION-200 apparatus with the applicator moved 9.5 cm along the massage lines in the dorsal collar region during 15 minutes. The therapeutic course included 10 sessions of massage at regular intervals every other day. The control subjects did not receive PLFESF therapy. The analysis of the results obtained revealed the influence of effective PLFESF therapy on various biomarkers of ageing which gives reason to recommend this technique for the application for the normalization of hemodynamic parameters, the correction of asthenic-neurotic disorders, the improvement of the patients' well-being and, as a result, the reduction of the biological age and the prevention of premature ageing.

[The use of white and yellow turpentine baths with diabetic patients]. / Primenenie belykh i zheltykh skipidarnykh vann u bol'nykh sakharnym diabetom.

In patients with insulin-dependent diabetes mellitus while and yellow turpentine baths produced a positive effect on carbohydrate metabolism. White baths were more effective in respect to lipid metabolism, blood viscosity, produced a good effect on plasmic hemocoagulation factors. Both while and yellow turpentine baths were beneficial for capillary blood flow: initially high distal blood flow in patients with prevailing distal polyneuropathy decreased while in patients with macroangiopathy initially subnormal blood flow increased. Both white and yellow turpentine baths promoted better pulse blood filling of the lower limbs and weaker peripheral resistance of large vessels. In patients with non-insulin-dependent diabetes mellitus white and yellow turpentine baths contributed to normalization of carbohydrate metabolism. Yellow baths were more effective in lowering lipids. White baths induced inhibition of platelet aggregation but had no effect on coagulation, yellow baths promoted a reduction of fibrinogen but had no effect on platelet aggregation. Yellow baths produced more pronounced effect than white ones on blood viscosity and microcirculation. Both yellow and white baths stimulated pulse blood filling, corrected peripheral resistance of large and small vessels of the lower limbs.
