The article presents the results of the study of the peculiarities of the respiratory system functioning in unfavorable environmental conditions in workers involved in industrial production and agrarian sector, taking into account the type of constitution of their bodies. Investigation of the influence of the complex of anthropogenic factors associated with production on the parameters of the respiratory system revealed a significant level of interconnection of the investigated parameters with anthropometric indicators. During the experiment, a significant decrease in the functional lung capacity in the studied subjects involved in industrial production was shown, compared with the control group and workers of argo-industrial production. Such a trend may be evidence of functional violations of tracheobronchial conduction, which is indirectly confirmed by the values of the Tifno index, which is the main method of an objective assessment of respiratory tract imperfections, and which is characterized by significantly lower values in the group of workers involved in industrial production compared with residents relative to environmentally friendly areas. The analysis of the pneumatachographic survey performed on the basis of the Pignier index revealed some differences in the functional parameters of the respiratory system in the groups of hyposthenics (capacity of the lungs) and hypersthenics (maximum volume velocity of 75 %). In the group of normosthenics, intergroup differences were found for the values of functional lung capacity in comparison with all groups, and for the Tifno index, the reliable difference between the indicators was noted only between the group of industrial workers and the control group.

Aim. To evaluate the structural and functional changes in the lungs of ST elevation myocardial infarction (STEMI) patients with absence or presence of chronic obstructive lung disease (COPD), and the relation with myocardial dysfunction and systemic inflammation.Material and methods. Totally, 189 STEMI patients included: group 1 — STEMI with COPD of moderate and mild grade, 2 — STEMI with no lung pathology. Groups were comparable by clinical and anamnestic parameters. Assessment of lung function and blood collection were done at 10­12 day of STEMI. For comparison of the parameters representing structural and functional changes in the lungs and comparison of C­reactive protein (CRP), N­terminal pro­brain natriuretic peptide (NT­proBNP) concentration, a control group was formed with no pulmonary pathology, comparable by age and sex with the STEMI patients.Results. In COPD patients, higher values revealed of the parameters representing the part of residual volumes in pulmonary structure. Higher residual volume (RV) was found also in STEMI and no COPD comparing to controls, however the relation RV/TLC (total lung capacity) was not higher than normal range. In both groups there were lower values of diffusion lung capacity (DLCO) comparing to controls. The lowest DLCO found in COPD patients. Concentration of NT­proBNP (H=41,6; p<0,001) and CRP (H=38,6; p<0,001) in COPD was significantly higher in STEMI with no COPD patients than in controls. The negative correlations found for NT­proBNP and CRP with forced expiratory volume 1 sec, FEV/FVC1, DLCO, and positive — with the values of thoracic volume, RV/TLC.Conclusion. In STEMI patients the increase revealed of residual lung volumes. Mostly the level of residual volumes is high in STEMI and COPD patients. There are associations of NT­proBNP and CRP with structural and functional parameters of the lungs regardless of COPD.

Aim. To study the prognostic value of the results of dynamic capnography in the complex assessment of parameters of the respiratory system in 6-minute walk test in patients with chronic heart failure (CHF). Materials and Methods. 73 Patients were examined: the group of study included 48 patients with IIA or IIB stage CHF (mean age 57.94.6 years, 23 men), the control group included 25 practically healthy volunteers (mean age 47.63.5 years, 9 men). The patients were conducted complex determination of parameters of the respiratory system: clinical scaling before and after 6-minute walk test (6MWT), instrumental examinations including spirometry, capnography and pulse oximetry before, during and after physical activity. The analysis of survival was conducted on the basis of the dynamic follow-up of patients within 5 years (60 months). Results. In the analysis of parameters of dyspnea at rest, all the parameters were higher in the group of patients with CHF (р0.05). The distance walked by the patients with CHF in 6 minutes was 488.2390.84 m, which was significantly less than in the control group (815.6053.89 m, р=0.009). Dyspnea as the cause of stoppage/slowing down of walking in 6MWT, was also more often recorded in patients with CHF (93.83.0% and 48.05.1%, р=0.049). Besides, in 6MWT the patients noted: weakness in legs (50.15.0% in the group of CHF and 40.05.0% in the control group, р=0.014), palpitation (29.04.6% and 20.04.1%, respectively, р=0.004). Worsening of dyspnea parameters in 6MWT was more evident in patients with CHF than in the control group (р0.01). In the CHF group, hypocapnic type of ventilation was revealed in 6MWT, analysis of РЕТСО2 trend graphs revealed a wave-like increase in the parameters, the so called periodic breathing (PB). CO2 trend was recorded in CHF group in 58.31.0% of cases (the difference with the control group with р=0.046), the trend of heart rate in 18.80.3% of cases (р=0.027). Cox proportional hazards regression analysis of mortality in patients with CHF showed a prognostic significance of a complex model comprising the following parameters of a patient: body mass index (р=0.005), left ventricular end-diastolic dimension (р=0.034), left ventricular end-systolic dimension (р=0.002), left ventricular ejection fraction (р=0.041), 6MWT distance (р=0.004), desaturation (р=0.009), and the presence of signs of PB during 6MWT (р=0.005). Model coefficients were statistically significant at р0.0001. Conclusions. Dynamic capnography and pulse oximetry allow to identify signs of PB in patients with CHF during 6MWT which may deepen a complex assessment of parameters of the cardio-respiratory system in patients with CHF in order to determine tolerance to physical exercise as well as the effectiveness of the conducted treatment. Complex assessment of survival of patients with CHF showed prognostic significance of the following parameters of a patient: body mass index, left ventricular end-diastolic dimension, left ventricular end-systolic dimension, left ventricular ejection fraction, 6MWT distance, desaturation, PB during 6MWT.

Material and methods. The study included patients (n=164) in peri- and postmenopause, having a laboratory-confirmed picture of the genitourinary menopausal syndrome - atrophic vulvovaginitis and suffering from recurrent lower urinary tract infections (UTI) - cystitis and urethritis. All patients underwent standard antibacterial therapy (ABT) UTI in accordance with the results of bacteriological urine culture according to Russian clinical guidelines on urology. Against the background of ABT, 164 patients received additional therapy with Trioginal® (the study group - SG) containing estriol, micronized progesterone and Lactobacillus casei rhamnosus Doderleini 35 (LCR 35) lactobacillus strain. Trioginal® was administered intravaginally in two stages: for 20 days, 2 capsules per day, then for 10 days, 1 capsule per day. In the comparison group - CG (n=67) with ABT, Ovipol Klio® (estriol monopreparation) was additionally intravaginally used in two stages: for 14 days, 1 suppository per day, then for 2 weeks, 1 suppository 2 times a week. The control group consisted of 30 patients receiving only standard ABT UTI, local hormone therapy for vulvovaginal atrophy (VVA) was not performed. The observation period was 12 months after the end of the course of therapy. At all stages of treatment, a subjective and objective assessment of the severity of urination disorders and urogenital atrophy (UDI-6 questionnaire), their impact on the quality of life of patients (questionnaire IIQ-7), indicators of bacteriuria, bacterial urine culture and vaginal biocenosis, frequency of undesirable phenomena were carried out. According to the initial characteristics of the group of patients were comparable. Results. At all stages of the study, in the group of patients who received therapy with the use of the Trioginal® drug, there was a significant improvement in the clinical picture of urination disorders compared to the CG and the control (main) group - MG (in SG - 18% at the end of therapy versus 100% before the start of therapy; CG - 26 % versus 100% respectively; Ledger - 58% versus 100% respectively; p

Abstract Background Electronic cigarettes have been a popular alternative to tobacco smoking. The effect of tobacco smoking on nasal airway resistance has been investigated before; however, the effect of the aerosol generated by electronic cigarettes is still unknown. This study aimed to evaluate the short-term effects of e-cigarettes on nasal airway resistance. Methods Sixty-one participants were recruited into a vapers group and a control group. The vapers group was instructed to smoke for 5 minutes, and their nasal resistance was measured pre-procedure and at 1 and 5 minutes post-procedure. The results were compared between both groups. Results Repeated measures analysis of variance demonstrated that vaping has no statistically significant effect on total nasal airway resistance. Conclusion Although the differences between both groups were not statistically significant overall, the vapers group showed a reduction in nasal airway resistance in the short term.

Abstract Introduction To improve the quality of life in nursing homes, meaningful activities and social contact are indispensable. Exergames can play a role addressing these needs. Methods In a randomized single blinded controlled intervention study, we investigated the effect of playing exergames on general wellbeing, fun and on social interaction. Results Thirty-five residents participated: 18 residents took part in the intervention group and 17 in the control group. The median mental wellbeing score of the intervention group increased from 42/50 to 45. The median sleep score of the intervention increased from 23/30 to 28. The median pain score of the intervention group improved from 18/20 to 20. The median score on subjective cognition increased from 24/30 to 26 while the mean scores on the objective assessment decreased from 1.8/2 to 1.7. Coaches gave an average fun score of 8.9/10 and an average intensity of exercise score of 11.6/20. Residents and coaches appreciated the social contact. Coaches reported a high feasibility (average of 4.1/5) but a low accessibility and a high intensity of supervision. Conclusions Exergaming is a feasible and pleasant complement to the usual activities with a positive impact on wellbeing, sleep, pain, and perceived cognition. Future research should focus on vulnerable groups and aim to develop a study in an implementation design.

ObjectivesThe aim of this study was to establish quantitative values for asymptomatic and symptomatic Achilles tendons.DesignCohort study with a single (cross-sectional) time point of patients diagnosed with unilateral Achilles tendinopathy and an asymptomatic group with comparative homogeneity.MethodsA sample of 50 participants: 25 diagnosed with symptomatic unilateral Achilles tendinopathy (AT group) and 25 with asymptomatic Achilles tendons (control group 2). The asymptomatic side of the AT group was used as a control (control group 1). Measurements at 2 cm intervals on the tendon from its insertion at the calcaneum up to the musculotendinous junction were taken non-weight bearing (NWB) and weight bearing (WB) using the MyotonPRO.ResultsThere was a significant (p<0.005) decrease in natural oscillation frequency (F) at points 2, 3 and 4 of the AT group (NWB condition) and points 2 and 3 for the WB condition. There was a significant (p<0.005) increase in logarithmic decrement (D) at points 2 and 3 signifying a decrease in elasticity. Dynamic stiffness (S) was significantly (p<0.005) reduced in the AT group at points 2 and 3 WB and point 3 WB. There was no significant difference in creep (C) observed between the symptomatic and asymptomatic tendons. There was a significant (p<0.005) increase in mechanical stress relaxation time (R) at point 2 NWB.There was a correlation between body weight and gender on tendon mechanics, with the symptomatic tendons. No significant differences were observed between the control group 1 and control group 2.ConclusionsThe MyotonPRO measured decreased stiffness over a section of the tendon corresponding clinically with Achilles tendinopathy. This may have potential in identifying risk of injury and informing rehabilitation, however further extensive research is required to generate baseline data for specific population groups monitoring variables over time. Age, gender and body mass index appear to have some bearing on the mechanical properties of the tendon but mainly in the tendinopathy group.

Chemical, physical, and mechanical methods are used to control human lice. Attempts have been made to eradicate head lice Pediculus humanus capitis by hot air, soaking in various fluids or asphyxiation using occlusive treatments. In this study, we assessed the maximum time that head lice can survive anoxia (oxygen deprivation) and their ability to survive prolonged water immersion. We also observed the ingress of fluids across louse tracheae and spiracle characteristics contrasting with those described in the literature. We showed that 100% of lice can withstand 8 h of anoxia and 12.2% survived 14 h of anoxia; survival was 48.9% in the untreated control group at 14 h. However, all lice had died following 16 h of anoxia. In contrast, the survival rate of water-immersed lice was significantly higher when compared with non-immersed lice after 6 h (100% vs. 76.6%, p = 0.0037), and 24 h (50.9% vs. 15.9%, p = 0.0003). Although water-immersed lice did not close their spiracles, water did not penetrate into the respiratory system. In contrast, immersion in colored dimeticone/cyclomethicone or colored ethanol resulted in penetration through the spiracles and spreading to the entire respiratory system within 30 min, leading to death in 100% of the lice.

Abdominal distension (AD) occurs in pregnancy and is also commonly seen in patients with ascites from various causes. Because the abdomen forms part of the "chest wall," the purpose of this study was to clarify the effects of AD on ventilatory mechanics. Airway pressure, four (vertical) regional pleural pressures, and abdominal pressure were measured in five anesthetized, paralyzed, and ventilated upright pigs. The effects of AD on the lung and chest wall were studied by inflating a liquid-filled balloon placed in the abdominal cavity. Respiratory system, chest wall, and lung pressure-volume (PV) relationships were measured on deflation from total lung capacity to residual volume, as well as in the tidal breathing range, before and 15 min after abdominal pressure was raised. Increasing abdominal pressure from 3 to 15 cmH2O decreased total lung capacity and functional residual capacity by approximately 40% and shifted the respiratory system and chest wall PV curves downward and to the right. Much smaller downward shifts in lung deflation curves were seen, with no change in the transdiaphragmatic PV relationship. All regional pleural pressures increased (became less negative) and, in the dependent region, approached 0 cmH2O at functional residual capacity. Tidal compliances of the respiratory system, chest wall, and lung were decreased 43, 42, and 48%, respectively. AD markedly alters respiratory system mechanics primarily by "stiffening" the diaphragm/abdomen part of the chest wall and secondarily by restricting lung expansion, thus shifting the lung PV curve as seen after chest strapping. The less negative pleural pressures in the dependent lung regions suggest that nonuniformities of ventilation could also be accentuated and gas exchange impaired by AD.

Body Plethysmograph

Functional residual capacity (FRC) and pressure-volume (PV) curves of the lung, chest wall, and total respiratory system were studied in 15 anesthetized rats, weighing 307 +/- 10 (SE) g. Pleural pressure was estimated from the esophageal pressure measured with a water-filled catheter. The FRC determined by body plethysmograph was slightly and significantly larger than FRC determined from saline displacement of excised lungs. The difference may be accounted for by O2 uptake by lung tissue, escape of CO2 through the pleura, and abdominal gas. Paralysis in the prone position did not affect FRC, and abdominal gas content contributed only slightly to the FRC measured by body plethysmograph. Values of various pulmonary parameters (mean +/- SE) were as follows: residual volume, 1.26 +/- 0.13 ml; FRC, 2.51 +/- 0.20 ml; total lung capacity, 12.23 +/- 0.55 ml; compliance of the lung, 0.90 +/- 0.06 ml/cmH2O; chest wall compliance, 1.50 +/- 0.11 ml/cmH2O; and respiratory system compliance, 0.57 +/- 0.03 ml/cmH2O. The lung PV curve did not show a consistent change after the chest was opened.

<p><em>The purpose of the work</em><strong> </strong>is to identify the influence of various components of the training load on the improvement of sportsmanship of athletes at the stages of preliminary training and initial specialization. <em>Research methods</em>. Students at the age of 17, who were engaged in the athletics section and performed regulatory tests at the level of the third sports category, were divided into 2 groups: experimental and control (10 people each). The students of the experimental group were trained in the author's 6-component training load program. The students of the control group were engaged in a program developed at the Research Institute of Physical Education and Sport. Investigated indicators of physical development (height, body weight, functional reserves of the cardio-respiratory system) and physical fitness (endurance, speed and power indicators) every 6 months for 5 years. <em>Results</em>. The developed program, which is implemented at the stages of preliminary training and initial specialization of athletes, provides for the development of specially oriented physical abilities and allows you to increase the level of sportsmanship. This is indicated by the dynamics of the obtained positive results of testing basic anthropometric data and indicators of physical training of students-athletes. It is also necessary to take into account the direction of development of physical abilities, based on the development of the main indicators of the cardio-respiratory system and the leading role of the mechanisms influencing the regulation of the level of general endurance, movement speed and strength characteristics in the whole organism. The program provides for a systematic, but gradual complication of physical activity, determines the appropriate conditions for the implementation of the basic principle of physical education in higher educational institutions and developmental training for students-athletes of various qualifications. <em>Conclusion</em>. The results of 5-year testing of students-athletes after the introduction of the author's program in the training process, indicate pronounced positive changes in physical development and physical fitness, expressed in increasing the level of their sportsmanship and achievement of sports results corresponding to the first sports category.</p>
