ABSTRACT
Introduction: During the COVID-19 caused lockdown, when students had to study on-line, they became highly vulnerable to stress. How different were the attitudes of university students towards COVID-19 in such situation in different countries? Objectives: The goal is to determine the differences in attitudes to COVID-19 during the lockdown among university students in Russia and Uzbekistan Methods: In May 2020, there was an on-line survey of 163 students of both genders in Ulianov Chuvash State University in Russia and of 49 university students from Bukhara, Samarkand and Andijan in Uzbekistan. The instrument used was 'Attitude towards COVID-19 Questionnaire' (Nikolaev, 2020). Result(s): The comparison revealed that Uzbek students are more interested in the latest COVID-19 news than Russian ones (p=.0004), they also consider this pandemic as severe and dangerous for people (p=.0006), and think that governmental measures to fight coronavirus are adequate (p=.0008). Russian students in their turn, as compared with their Uzbek peers, feel highly concerned about the risk of their own infection (p=.00001), as well as the threat to their own life (p=.00546) and the life of their relatives and closest ones (p=.0005) as a result of coronavirus spread. In addition, Uzbek students regard themselves healthier than Russian ones (p=.0329). Students' self-estimation of happiness does not differ (p=.0776). Conclusion(s): Differences in attitudes to COVID-19 among students are associated with more apparent socially oriented behavior of students from Uzbekistan, and more personality-oriented behavior of Russian students.
ABSTRACT
COVID-19 has become a global pandemic affecting more than 260 million people and taking more than 5 million lives (WHO data from December 2021). The infection has a unique interaction with the cardiovascular system and is associated with an increased risk of arterial and venous thromboembolic complications. Aim: To evaluate the impact of the COVID-19 pandemic and the concomitant COVID-19 infection on the characteristics of patients with acute myocardial infarction (AMI) and its course. Material and methods: We analyzed all patients admitted for AMI with and without ST-segment elevation for the period November 1, 2020 - February 1, 2021, at National Heart Hospital, and they were further compared according to the presence of COVID-19 infection. The control group included patients with AMI treated between March 13 and May 13, 2019 when no case of COVID-19 had been reported worldwide. The comparative characteristics include risk profile, index event, examinations and treatment performed, and the scores GRACE, CRUSADE, SAPS II, APACHE II and mSOFA.
ABSTRACT
Introduction. New coronavirus infection (COVID-19) contributes to the aggravation of respiratory symptoms in patients with COPD, including affecting the intensity and nature of cough. Hypertonic solution (HS) has a positive effect on the rheological properties of sputum and mucociliary clearance. However, there are no studies in the available literature on the use of HS in patients who have undergone COVID-19. Goal. To evaluate the effect of the combination of 7% hypertonic saline and 0.1% natrii hyaluronas on the intensity and productive nature of cough in patients with COPD who have undergone a new coronavirus infection and the safety of its use in this cohort of patients. Materials and methods. 50 patients with severe COPD in remission who suffered a new coronavirus infection were examined. The rehabilitation stage of treatment was carried out in the conditions of the pulmonology department. From the moment of receiving the last negative PCR result for SARS-CoV-2 to admission to the hospital for rehabilitation, it took from 2 to 3 weeks. The duration of follow-up of patients was 10 days. The patients were divided into two groups: group 1 (n = 25) - patients who received combination of 7% hypertonic saline and 0.1% natrii hyaluronas 7% by inhalation through a nebulizer;group 2 (n = 25) - patients who did not receive combination of 7% hypertonic saline and 0.1% natrii hyaluronas. The severity of cough was assessed (cough severity scale;shortness of breath, cough and sputum scale), clinical and biochemical blood tests, ECG, spirometry. Results. In patients treated with combination of 7% hypertonic saline and 0.1% natrii hyaluronas, a significant decrease in the severity of cough, the amount of sputum was revealed. The tendency to reduce shortness of breath and improve the quality of life is determined. No serious adverse events were detected when using the drug. Conclusions. The use of the combination of 7% hypertonic saline and 0.1% natrii hyaluronas in patients with COPD who have suffered a new coronavirus infection at the rehabilitation stage leads to a decrease in the intensity of cough and improved sputum discharge, which helps to reduce the severity of shortness of breath and improve the quality of life. The use of the drug is safe and does not lead to clinically significant adverse events. © 2021, Remedium Group Ltd. All rights reserved.
ABSTRACT
For cooling small volume compartments, the thermoelectric systems have a number of advantages over the classic compressor refrigerators. Their priority is due to the active components in their design - Peltier modules which are chemically inactive, have no moving parts and do not practically need maintenance [1-2]. The thermoelectric cooling systems have the potential to meet the requirements for storing and transportation of vaccines and other medical solutions at low temperatures posed by the global pandemic of Covid-19. The electrical systems in the vehicles are excellent prerequisite for compatibility with the thermoelectric refrigerators requiring stable power supply.The aim of the present work was to design, realize and study a prototype of a small scale mobile thermoelectric cooling system for negative temperatures based on Peltier modules. © 2021 IEEE.
ABSTRACT
IntroductionYoung people, regarded as less susceptible to the virus, may differently perceive the situation associated with the COVID-19 outbreak.ObjectivesTo determine the differences in perception of COVID-19 and preventive actions taken against it by domestic and international university students under the spreading threat of COVID-19 illness.MethodsDuring the outbreak of COVID-19, 224 domestic and 312 international students of Russian universities responded via on-line to the self-constructed Attitude towards COVID-19 Questionnaire.ResultsThe showings of the international students were surely higher than those of domestic students in seriousness of their evaluation of the COVID-19-related situation in the world (p=.0006), in the country (p=.0096), and in the region (p=.0390);in the evaluation of the virus-related risks for aged and chronic patients (p=.0075), in adequacy of measures taken by the government against COVID-19 (p=.0114), in degree of disturbing their customary way of life (p=.0363), and ruining their plans for the future (p=.0161). The international students, who live mostly not at their homes and have a higher stress level (p=.0227), showed higher interest to COVID-19-related news (p=.0001), they were stricter in taking preventive measures: in wearing a mask, washing hands, keeping the distance in order to reduce the risk of the virus infection (p=.0009).ConclusionsDuring the COVID-19 outbreak, both the international and domestic students are calm in perceiving the threat to their health and life. At the same time, with a higher stress level, the international students are more watchful concerning the situation of COVID-19 spread, and they more strictly obey the restrictive measures.
