Background: The existing data demonstrate the potential role of trace elements in nasal mucociliary clearance, although the association between trace element and mineral status and ciliary function in children with chronic rhinosinusitis is insufficiently studied. Therefore, the objective of the present study is evaluation of trace element and mineral status and mucociliary function in pediatric CRS patients before and after functional endoscopic sinus surgery. Methods: The present study involved 30 children with chronic rhinosinusitis without nasal polyps. During this follow-up the patients were examined preoperatively (point 0), underwent functional endoscopic sinus surgery, and were repeatedly examined at three months postoperatively (point 1). At both points the patients were subjected to quality-of-life assessment using SNOT-20 questionnaire; endoscopic and computer tomography examination of the nasal sinuses; evaluation of ciliary function and mucosal cytology using high-speed videomicroscopy; assessment of blood count and inflammatory markers; as well as analysis of trace element and mineral levels in whole blood, serum, and hair using inductively-coupled plasma mass-spectrometry. Results: The obtained data demonstrate that endoscopic sinus surgery significantly improved sinonasal pathology in children with chronic rhinosinusitis, as evidenced by significantly reduced Lund-Mackay, Lund-Kennedy, and SNOT-20 scores. At the same time, no significant improvement of ciliary functions or mucosal cytology was observed postoperatively. Trace element status assessment demonstrated that postoperative serum Zn, whole blood Mg and Cu were significantly lower as compared to preoperative values. In contrast, serum Mn and Cr, as well as whole blood Cr and hair Se were characterized by a significant increase at three months postoperatively. Multiple linear regression analysis demonstrated that serum Zn is significantly associated with the number of ciliated cells and cell viability, whereas serum Mn and whole blood Cu concentrations are inversely associated with cell viability and ciliary length, respectively. Hair Se was found to be associated with the number of neutrophils in the mucosa biopsy. Conclusion: Redistribution of trace elements and minerals may at least partially mediate prolonged recovery of mucosal ciliary function in children with chronic rhinosinusitis in three months after functional sinus surgery, although the particular mechanisms of these alterations in trace element levels are to be discovered.

The objective of the present study is to explore frequency, pattern and evolution of lesion-discordant aphasia following first ever acute stroke in Bengali-speaking subjects. Methods: Bengali version of Western Aphasia Battery, a validated scale, was used for language assessment in our study subjects. Lesion localization was done by using Magnetic resonance imaging (MRI) (3T) for ischemic stroke (if not contraindicated) and computed tomography (CT) for hemorrhagic stroke. Among 515 screened cases of first-ever acute stroke, 208 presented aphasia. Language assessment was done between 7 and 14 days in all study subjects and was repeated between 90 and 100 days in patients available for follow-up. Ischemic stroke cases with contraindication for MRI underwent CT imaging. Discordance between lesion and aphasic phenotype was determined only for right-handed subjects with cortical involvement (isolated or in combination with sub-cortical white matter) in the left hemisphere. Appropriate statistical tests were used to analyze the collected data. Results: Lesion-aphasia discordance was found in 20 out of 134 patients with aphasia who were dextral and had cortical involvement in the left hemisphere (14.92%). The pattern of discordance observed were- posterior lesion with Broca's aphasia (4; 20%); posterior lesion with global aphasia (8; 40%); anterior lesion with global aphasia (4; 20%), and posterior lesion with mixed transcortical aphasia (4; 20%). On univariate analysis, the factors significantly associated with lesion-aphasia discordance were hemorrhagic stroke (p = 0.000); posterior perisylvian location (p = 0.002), and higher education (p = 0.048). After adjusting for all other variables, hemorrhagic stroke was found to have strong association with lesion-aphasia discordance (p = 0.001, OR = 11.764, 95% CI, 2.83–50.0). Discordant cases were more likely to recover or change to a milder type compared to concordant cases (p = 0.007, OR = 11.393, 95% CI, 1.960–66.231), after adjusting for all other variables including initial severity of aphasia (p = 0.006, OR = 8.388, 95% CI, 1.816–38.749). Conclusion: Lesion-aphasia discordance following acute stroke is not uncommon among Bengali-speaking subjects. In the discordant group, preponderance towards non-fluent aphasia was observed. Discordance occurred more frequently after hemorrhagic stroke. Subjects with lesion-discordant aphasia presented better recovery during early post-stroke phase.

The modern model of inpatient surgical care of private and optimized state/govermental medical institutions allows us to change the paradigm of nosological attachment of the hospital bed to one profile of specialists for an adaptive model, when the wards can be reassigned depending on the needs of the hospital. In such multidisciplinary medical centers with mixed hospital beds without a nominal distinction in the nosological departments, a new therapeutic service is being developed - hospitalists, which provide a consistent curation of hospitalized patients, compensation of chronic therapeutic illnesses with patient's preparation for surgical interventions. Our work describes the experience of Fast Track recovery program with the active participation of a hospitalist in a surgical team, which is a new experience in the practice of Russian colorectal surgery.

Restoration of the body is the return of physical parameters to the initial values, increasing the adaptive capacity after performing physical work. Proper recovery after exercise helps avoid problems such as physical fatigue, lack of nutrient intake, injuries of various severity, dehydration, etc. A number of factors influence the human body during recovery: a balanced diet, adequate rest and sleep, psychological and emotional unloading, gymnastics, massage, contrast shower and others. Comprehensive rehabilitation programs in sports should include methods with proven effectiveness, take into account the individual characteristics of the athlete and the dominant form of physical activity, and consider the recovery period as an integral part of the entire training plan.

BACKGROUND: Physical overload results in the development of pathological changes in the organs and systems and thereby causes their dysfunction. This leads to disadaptation, vegetative imbalance, and disturbances in the cardiovascular, nervous, endocrine and other systems. Taken together, these changes give rise to a syndrome of overtraining. In this context, the pathogenetically sound method of therapy appears to be the most suitable for the management of this condition based on the physiotherapeutic non-invasive interventions for the correction of physiological characteristics and the psycho-emotional status of the patients. One such method is bioresonance therapy (BRT). AIM: The objective of the present study was to evaluate the influence of bioresonance therapy (BRT) on the health status of the athletes presenting with the overtraining syndrome. MATERIAL AND METHODS: The study included 60 athletes presenting with the overtraining syndrome. They were divided into two groups each comprised of 30 subjects of comparable age, sex, sport, and sports qualification. Group I was composed of 30 athletes who were treated by means of bioresonance therapy. Group II (control) contained the athletes who received placebo procedures (i.e. the procedures with the use of a non-functioning device). All the athletes were examined before and after the treatment with the application of the clinical and instrumental methods. RESULTS: The study has demonstrated that the use of bioresonance therapy significantly increases the parasympathetic influence on the rhythm of the heart, reduces the stress on the central contour of its regulation, contributes to the 'economization' of the cardiac activity; has an antihypertensive effect (more pronounced with respect to systolic blood pressure (SBP)), has a normalizing effect on the variability of blood pressure (BP) in the patients with initial BP instability, and significantly decreases the time index in connection with monitoring blood pressure; moreover, BRT has a normalizing effect on the circadian rhythm of BP and corrects the rate of the morning rise in diastolic blood pressure (DBP). CONCLUSION: Bioresonance therapy can be considered as a method for the correction of the syndrome of overtraining in the athletes with the enhanced activity of the sympathetic nervous system.

The witness of the problem actuality is also an existence of controversial opinions and absence of clear definitions on properties of the condition. It has been revealed that the main role in pathogenesis of the overtraining syndrome do play the changes of cardiovascular, endocrine and central nervous systems. These changes are complicated and ambiguous, depend upon multiple factors, as the type of sport, specifics of exertion and loads, stage of pathophysiological process. Entraining effect of exertion, if incorrectly utilized, underestimation of current condition of a sportsman, might not lead to expected results. Moreover, non-rational application of exertion might lead to opposite effect, that is, to decrease adaptation potential and reserves, towards the edge of the condition as an overtraining syndrome, which shows phasic, progressing character, starting from fatigue and mild disorders, to persistent, rigidly reversible processes. Due to controversy, multiple stages and multifactorial of the overtraining syndrome, by now there is no unified approach to its definition, as no unified standards to its diagnostics, treatment and prevention.
