The Physical Development and Physical Preparedness of the Students at the Age of 17-20 Years Old Who Go in for Track and Field

The impact of regular track and field trainings on student’s physical development and physical preparedness have been studied in the work. The study was conducted in the Kyrgyz-Turkish Manas University. İn total, 64 students at the age of 17-20 years have participated into the study. Applied methods: anthropometry, physiometry, the Stange-Hench tests. Sports and pedagogical control tests (on flexibility, strength, speed, endurance and agility) have been used as well.While evaluating students’ physical development, the second study of both ‘Sports’ and ‘Initial’ groups has revealed the high indices among boys according to the following criteria: body height and weight, chest bulk, vital capacity, chest excursion and the Stange-Hench tests. According to the heart rate criterion, the indices of the “Sports” group were reliably higher than those of the “Initial” group (P < 0.05). During the comparison of the second study results of girls’ physical development, more reliable distinctions have been found out (P < 0.05). When the physical development indices were under the study, the second examination exposed and proved that the flexibility of boys from ‘Sports’ group being higher on 7.1 cm (P < 0.05).The experimental materials provided in this article gave an opportunity for concluding that systematic track and field trainings had had a positive impact on the physical development indices, to be precise on the functional condition and physical preparedness level of boys and girls at the age 17-20 years old.

The possibilities of the highlands in optimizing the condition of athletes

The objective of the research is to study the influence of restorative motor mode at the high altitude on functional condition of the sportsmen body during their stay in the mountains and the subsequent readaptation period. Materials and methods. Ten male sportsmen, whose specialization was medium and long-distance running took part in the research. The research was conducted in Bishkek during the 3-week stay in highlands (2350 m) and after their return to the foothills. During their stay in the mountains the sportsmen followed a specific motional mode in the form of outdoor activities. At the high altitude (2nd, 7th, 12th and 22nd days) and during the readaptation period (5th–6th and 18th–19st days) the condition of the respiratory function, cardio respiratory system and the maximum level of oxygen intake of sportsmen were evaluated. Results. During their stay in the mountains the increase of external expiration reserves and optimization of cardiovascular activity were observed. The level of maximum oxygen consumption after a decrease increased during the period of readaptation by 9,8% (P < 0,05). Conclusions. Outdoor activities at the high altitude conditions allow you to preserve and expand the functional reserves of the body of sportsmen during the transient period of the oneyear training macrocycle.

Finite Element Analysis and Long-Term Monitoring of a Highway Overpass Bridge with Newly Constructed Link Slabs and Modified Bearings

Joint failure, which causes leakage in bridge decks as well as deterioration in girders and substructures, is one of the most common concerns in highway bridges. Therefore, link slabs have been considered as a preventive maintenance method in eliminating these joints. This paper presents a pilot project that constructed the link slab system in Maryland, U.S., with modified bearings to improve its durability and reduce maintenance costs. Compared with the traditional bearing replacement design for the link slab systems, this project proposes a more economical method by removing the anchor bolts and restricting sliding plates of the fixed bearings at both abutments to match the designed boundary conditions while avoiding the high cost of jacking girders and replacing bearings. Furthermore, numerical analysis and structural health monitoring were conducted and validated to investigate the effectiveness of the link slab design with various high performance concrete materials. After the one-year monitoring period, the link slab system is verified to be in fully functional condition and the bearing modification design is verified to be effective.

Cyclic vomiting syndrome responding to amisulpride – A case report

Cyclic vomiting syndrome (CVS) is an uncommon functional condition defined by recurring episodic stereotyped vomiting with a sudden start and an unknown origin. CVS can be triggered by a variety of conditions, and the course and management are often determined by the triggering factors. We present the case of a 13-year-old female youngster who complained of frequent bouts of vomiting that coincided with the onset of menses. We started her on oral amisulpride 50 mg a few days before each menstrual period. As a result of the treatment, in the following menstrual cycle, she had a dramatic improvement in her symptoms.

Prevention of inflammatory changes in the denture-bearing mucous membrane

Relevance. Advanced clinical and cytological studies have not been conducted yet to examine denture adhesive effect on the prevention of inflammatory changes in the mucous membrane of the prosthetic bed, and thus, the prevention of denture-related stomatitis. Purpose: to assess the clinical and functional condition of the oral mucosa beneath the denture during the adaptation period using a denture adhesive cream to prevent inflammation of the denture bed mucous membrane.Materials and methods. The study clinically and cytologically (washing, scraping) assessed the condition of oral mucosa beneath complete acrylic dentures on days 14-16 and 28-30 of the adaptation period in 15 fully edentulous patients (main group), who used an adhesive cream after they were delivered their dentures, and in 21 fully edentulous patients (control group) who did not use the cream during the denture adaptation period. All the patients were elderly.Results. At different times of the adaptation period, the study more frequently detected inflammatory changes in the denture-bearing mucosa in subjects who did not use the denture adhesive cream. The cytological study confirmed the results of the oral clinical examination, as, at the end of the adaptation period, the number of cellular elements and various microorganisms was significantly lower in the main group than in the controls, which proved the effectiveness of the denture adhesive cream for the prevention of denture stomatitis.Conclusions. Regardless of sex, patients with complete acrylic dentures, who used a denture adhesive cream, had a lower bacterial accumulation on the prosthetic bed and inflammatory changes during the adaptation period, which allowed us to recommend the adhesive cream for the prevention of denture stomatitis.

DOES PARTIAL MENISCECTOMY AFFECT ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION RESULTS?

ABSTRACT Objective: To compare the application of partial meniscectomy concomitant with primary ACL reconstruction, using the graft from the patellar tendon with individuals who underwent only ACL reconstruction, in clinical functional criteria and degree of osteoarthritis (OA), after 10 years of the surgical process. Methods: This is a retrospective cross-sectional study with 37 patients who underwent ACL reconstruction with a graft from the patellar tendon, associated or not with partial meniscectomy, divided into 2 groups: with meniscal injury (n = 22) and without meniscal injury (n = 15). Anthropometric data and four outcome measures were used to analyze the results: SF-36 questionnaire, arc of motion assessment, Knee injury and Osteoarthritis Outcome Score (KOOS), and Ahlbäck Radiographic Classification. Results: No differences were found for health-related quality of life, arc of motion, functional condition and knee OA severity/grade in patients who underwent partial or no meniscectomy in conjunction with ACL reconstruction (p > 0.05). Conclusion: Participants who underwent partial meniscectomy in conjunction with primary ACL reconstruction with a graft from the patellar tendon, after 10 years of the surgical process, showed no significant differences in the clinical functional criteria and severity of knee OA, compared to individuals who underwent only ACL reconstruction. Level of Evidence II, Prognostic study.

Dementia-Related Care in Acute Care Settings: A Qualitative Meta-Synthesis of Patient and Family Perspectives

Researchers have long emphasized the importance of a person-centered approach to health care, especially regarding the treatment of individuals living with dementia. However, the fast pace of acute care settings can be a difficult place to provide such care to patients, where there are tensions between the emphasis on efficient treatment of acute medical co-morbidities and person-centered dementia care. This paper is a meta-synthesis of qualitative studies examining perspectives of patients and their family members regarding their acute care experiences. It takes an interpretive approach, using primarily inductive reasoning to generate themes across available studies’ findings. Emergent themes are organized under two major dimensions of the hospital environment: the physical environment, including sensory and tangible elements, and the social environment, including the hospital atmosphere and communication practices. Persons with dementia feel overly stimulated by the busy physical environment of the hospital, yet they are often left to languish alone, sometimes even physically restrained. Patients reported feeling lonely, fearful, and confused, identifying diverse physical and social environmental attributes like physical clutter, noise, and lack of empathy from care providers as contributors. Based on acute care experiences and reports from patients and family members, although the acute condition is treated, persons with dementia often leave the acute care environment in worse functional condition than when they entered. Given the increasing prevalence of persons with dementia in acute care settings, it is clear that we must prioritize innovations and programs aimed at improving hospital practices, educating staff, and creating more dementia-friendly environmental designs.

Gearbox Mechanical Efficiency Determination by Strain Gauges Direct Application

This article describes a unique method of measuring the efficiency of gearboxes using foil strain gauges, which allows maintaining the current configuration of the gearbox within the overall assembly of the machine and its functional condition. The presented method is applicable to gearboxes located in the original equipment assembly without the need to use a test rig. Using foil strain gauges, the torque at the input and output of the gearbox is detected. Therefore, the accuracy of torque measurement is key. The crucial step is the calibration of the instrumentation to the given application conditions, which, in this case, is ensured by a virtual calibration using a very accurate FEM analysis. The accuracy of the position of strain gauges and virtual calibration of measurements generate inaccuracies affecting the resulting uncertainty of the determined efficiency. The present article shows, on the example of several measurements, that when using 24-bit converters, after processing the obtained data, mechanical stress with a sensitivity better than hundredths of an MPa can be reliably detected even without signal amplification from strain gauges. It follows that the efficiency is determined with an accuracy of better than low units of tenths.

Values of laryngeal stroboscopy in patients with chronic laryngitis exposed to occupational factors

Topicality: Chronic laryngitis occupies one of the leading positions in the structure of laryngeal pathology. Among other things in the etiology of chronic laryngitis, occupational factors, including a chemical exposure, play an important role. Laryngeal storoboscopy is one of the most informative methods of examination of the vocal apparatus in phoniatrics that allows observing rapid oscillating motion of the vocal folds during phonation, which cannot be seen without instrumental methods. Aim: to investigate the functional condition of the vocal apparatus based on the values of laryngeal storoboscopy in patients with chronic laryngitis who were exposed to chemical factors. Materials and methods: Seventy-five patients with chronic laryngitis and 15 healthy individuals of the control group were examined. The patients were divided into groups based on the type of chronic laryngitis (group 1 one was made up of those who had a catarrhal type, group 2 had subatrophic type patients) and the intensity of chemical factors in the production of nitrogen compounds (subgroup A included patients who worked in manufacturing workshops where the level of chemicals in the air did not exceed maximum allowable levels, whereas subgroup B experienced an exposure to elevated chemical levels). Groups 1A and 2A included 23 and 20 patients, respectively; groups 1 B and 2B were composed of 17 and 15 patients, respectively. The patients underwent a specialized phoniatric examination and they were determined the maximum phonation time (MPT). We performed a video laryngeal stroboscopic examination on the equipment complex of «Karl Storz» (Germany). The results were evaluated by calculating the integrated score of phonator oscillations recorded during a stroboscopic study. Results and discussion: Patients with chronic laryngitis – employees of the public joint-stock company «AZOT» were examined. This is a large chemical production with several manufacturing workshops involved into various technological processes. According to the intensity of the influence of chemical factors, the manufacturing workshops differ significantly; therefore the intensity of the influence of the factors of the production environment on the upper respiratory tract varies in those working in the production of nitrogen-containing compounds. We compared the results of the survey of patients included in subgroups A and B. The MPT in patients of group 1A was 18.6±1.6 sec versus 13.6±1.2 sec in group 1B; in group 2A, it was 13.4±1.1 sec versus 10.8±0.8 sec in group 2B and 21.2±1.6 sec in the control group. Values in all study groups significantly (p<0.05) differed from the control. Also in groups 1B, 2A and 2B, the MPT was significantly lower than in group 1A. Thus, in patients with chronic laryngitis, who worked in conditions of increased exposure to chemicals present in the air of the production environment, the recorded MPT was significantly lower than in the controls, which is indicative of the impaired function of the vocal apparatus. Based on laryngeal stroboscopy findings, voice dysfunction revealed in patients with chronic laryngitis was more often manifested by changes in the vibratory cycle, desynchronized vocal apparatus and weakened amplitude of oscillations. According to the average score of video laryngeal stroboscopy in all groups of examined patients with chronic laryngitis, a significant (p &lt;0.05) difference was revealed in comparison with controls, as well as between some groups. In particular, in group 1A the integrated score of laryngeal stroboscopy data was 7.9±0.2, in 1B – 8.8±0.6, in 2A – 10.5±0.8 and in 2B – 12.1±1.0. The normal value is 5.010±0.001. Patients with higher scores had more severe laryngeal impairments and disease course. In group 2 (both A and B subgroups), changes according to video laryngeal stroboscopy were significantly more pronounced than in group 1A. In group 2B, the impairments were more severe as compared with both subgroups of group 1 and group 2A. Thus, in all studied groups of patients with chron ic laryngitis there are seen significant impairments of the vocal apparatus. At the same time, based on the findings of clinical methods and objective instrumental examination, there is a tendency to the deterioration in the functional condition of the vocal apparatus with increased chemical exposure in production. In particular, in groups B, compared with groups A, there is a marked increase in the desynchronization of vibrational oscillations, the number of cases with lack of stroboscopic comfort increases, the number of cases of hypertonia of the vestibular larynx increases. Similar trends apply to other parameters of video laryngeal stroboscopy in groups. On the whole, a quantitative assessment with the help of scores of integrated laryngeal stroboscopy allows accurate determining the severity of changes in the phonatory activity of the vocal apparatus and objectifying the diagnosis of chronic laryngitis against the background of chemical factors. The obtained data will be useful for improving the quality of diagnosis of voice disorders in chronic laryngitis, they can also be beneficial for vocational selection and addressing issues of occupational examination. Conclusions: 1. An impaired voice function according to laryngeal stroboscopy in patients with chronic laryngitis was manifested by changes in the vibratory cycle, mainly by desynchronized vocal apparatus and weakened amplitude of oscillations. 2. With the help of video laryngeal stroboscopy it is possible to objectify, quantify and determine the severity of phonatorial disorders in chronic laryngitis against the background of the exposure to chemical factors. 3. The degree of voice dysfunction according to laryngeal stroboscopy in patients with chronic laryngitis depends on the level of chemical exposure.
