Authors: TOTH Constantin Silviu , MĂCUȚĂ Silviu Dănuți 
Published: April 2021

Rail transport is essential to the EU's strategy for a more sustainable transport sector, economic and social cohesion and connecting Europeans at and between each Member State. EU trend is to support the railway sector as a clean, main mode of transport at European level. The European rail system carries around 1.6 billion tones of freight and 9 billion passengers each year. The railway sector has a substantial contribution to the EU economy, directly employing over 1 million people. With the technological evolution of railway vehicles, it is important to focus on safety issues. Wheels are one of the most critical components of railway vehicles, as their failure can lead to derailment. Therefore, an exact project on the control of the problem of wheel fatigue and knowledge of the effective parameters on their life, can improve the life of the whole structure. Due to the fact that the nature of the loads applied to the wheels is repeated, fatigue is very common mechanism of damage that can occur in several ways, such as: nucleation and growth of fatigue cracks, spalling, shelling, and so forth. The main sources of these phenomena are the rolling contact loads, the thermal loads between the wheel-rail and the wheel-brake block, created in the braking phase, the presence of structural defects in the wheel material; it follows that they cannot be omitted in a rigorous design. Increasing of speed aggravates these factors and exacerbates the problem of thermal fatigue of the wheels. In this paper we present a series of studies that focused on the wear of the wheels of railway vehicles in contact with the steering track (rail) to fatigue.

Authors: Mugo Joyce Wangui , Uimbia Martin G 
Published: April 2021

Improving healthcare services has been paramount to both the national and county governments in Kenya. However, this broad national goal has failed to be achieved within the health sector in Kenya due to dilapidated systems, lack of coordination and poor quality of the health records within the industry. The current study sought to establish the influence of quality health records on improving healthcare in Kerugoya Level IV hospital. Specifically, the research focused on the creation of health information, relevance of health information, completeness and accuracy of patient’s health information and accessibility of health information on the improving of health services. The research was grounded on the negativity theory. The research adopted a quantitative design with a population of 288 staff members being targeted in the study. The sample respondents were 165 staff members with both quantitative questionnaires and interview schedules being utilized in the research. The study adopted quantitative techniques in the data analysis and thematical analysis. The findings showed that 87% of the sample respondents were able to participate in the study. The research concludes that creation of health information, relevance of information and accessibility of health records are significant predictors to improved healthcare services. The research revealed that the level of management support and resource availability are positive and significant predictors of the level of improved healthcare services in Kerugoya level IV hospital. The study findings noted there is a positive but insignificant relationship between completeness and accuracy of health information and improved healthcare services within the level IV hospital. The study recommends that the hospitals should improve the digitalization of health records which will foster storage and accessibility. The hospitals should also enhance coordination with the national government to improve their health infrastructure.
Relationship of granulocytic inflammation of bronches with the level of asthma control in patients with cold airway hyperresponsiveness under inhalation therapy of extrafine beclomethasone/formoterol
Authors: Pirogov A. B. , Prikhodko A. G. , Perelman J. M. 
Published: April 2021

Introduction. Obstruction of small airways in asthma is accompanied by greater hypersensitivity to nonspecific irritants and inflammation activity, which is associated with a worsening of the clinical course of the disease. The combination of beclomethasone dipropionate/formoterol fumarate (BDP/FF), used in the form of an extrafine metered dose aerosol, is capable of having an anti-inflammatory effect on the small airways. Dynamic changes in the structure and function of granulocytes of inflammatory bronchial infiltrate after exposure to cold air in patients with asthma treated with BDP/FF have been little studied.Aim. To study the nature of changes in eosinophil and neutrophil pools of bronchial granulocytes in asthma patients with cold airway hyperresponsiveness (CAHR) during long-term therapy with extrafine BDP/FF.Materials and methods. The clinical study involved 25 asthma patients with CAHR. The design of the work included a questionnaire survey of patients using the Asthma Control Test (ACT) questionnaire, spirometry (Easy on PC, ndd Medizintechnik AG, Switzerland), an isocapnic hyperventilation by cold air (IHCA), collection and cytological examination of induced and spontaneously produced sputum. The examination was carried out at the beginning and after 12 weeks of BDP/FF therapy (100/6 μg, twice a day).Results. 12-week treatment with extrafine BDP/FF led to an improvement in asthma control (ACT increased from 17.1±1.1 to 22.5±0.5 points, p˂0.001) and patency of small bronchi (increase in МEF50 was 0.47±0.21 L/s, МEF25-75 – 0.42±0.17 L/s). BDP/FF therapy had a positive effect on cellular inflammation, leading to a decrease in the number of eosinophils in sputum from 9.5 (3.0; 19.5) to 2.2 (1.3; 4.7)% (p˂0,05). A decrease in the number of eosinophils was also observed after cold bronchoprovocation: from 9.0 (2.8; 15.4) to 4.7 (2.8; 7.8)% (p˂0.05). There was no dynamics in neutrophils after BDP/FF treatment before and after IHCA (59.9±1.3 and 57.1±2.0%, respectively, p>0.05).Conclusion. Improvement of disease control in asthma patients with CAHR after 12 weeks of therapy with extrafine BDP/FF is associated with the regulation of eosinophilic inflammation, a decrease in the number of eosinophils in the airways and suppression of the activity of the neutrophilic pool of bronchial granulocytes in response to cold bronchoprovocation.

Introduction. Magnesium is directly involved in the regulation of lung function. However, the effectiveness of various magnesium preparations for activating lung function is not unambiguous. One of the reasons for this may be age-related differences in the nature of structural and functional changes in the lungs in response to the administration of magnesium.Aim. To study the reactivity of the lungs respiratory division of different ages rats to prolonged administration of magnesium chloride.Materials and methods. The experiments were performed on 48 male Wistar rats of 3 and 15 months of age. The experimental animals, in addition to the standard diet, received magnesium chloride at a dose of 50 mg/kg body weight daily for 21 days. At the end of the experiment, lung tissue samples were taken for histomorphological and biochemical studies.Results. At the end of the experiment, 3-month-old rats treated with magnesium chloride showed an increase in the size of the alveoli, a decrease in the relative area of the parenchyma and stroma, and an increase in the relative area of air spaces. A decrease in the thickness of the interalveolar septum and the concentration of oxyproline in the lung tissue of these rats may indicate a decrease in the number of connective tissue elements. In 15- month-old experimental animals, on the contrary, an increase in the relative area of the parenchyma and stroma of the lungs (by 14%), a decrease in the relative area of air spaces (by 12%), and an increase in the concentration of oxyproline in the lungs (by 21%) were observed.Conclusion. Thus, the research results indicate age-related differences in changes in morphological and biochemical parameters characterizing the state of the respiratory division of the lungs with prolonged administration of magnesium chloride. The nature and severity of these changes suggests that in 3-month-old rats magnesium increased lung activity, and in 15-month-old animals, on the contrary, it decreased.
