ABSTRACT
@#Electronic cigarettes are handheld electronic vaping devices which produce an aerosol by heating an e-liquid. The e-liquid typically contains humectants and flavorings, with or without nicotine; once vaporized by the atomizer, the aerosol (vapor) provides a sensation like tobacco also smoking the heating process can lead to the generation of new decomposition compounds that may be hazardous. Heavy metals, organic compounds, and particles smaller than PM2.5 were found on the puff of the electronic cigarette, also in 2012 International agency research cancer, introduced PM2.5 human carcinogen substance. Therefore, e-cigarette liquid products should be subjected to regulatory control to ensure consistent nicotine delivery. Global youth tobacco survey Mongolia 2019 asked about e-cigarette use status and 3.5% (95% CI: 2.6-4.6) of students currently used electronic cigarettes while one in ten students (10.1%, 95% CI: 8.3-12.2) had ever used electronic cigarettes. E-cigarette advertising is on television and radio in many countries that have long banned similar advertising for cigarettes and other tobacco products and may be indirectly promoting smoking conventional cigarettes. Smoke-free policies protect nonsmokers from exposure to toxins and encourage smoking cessation. Introducing e-cigarettes into clean air environments may result in population harm if use of the product reinforces the act of smoking as socially acceptable or if use undermines the benefits of smoke-free policies.
ABSTRACT
Background@#As of September 21, 2021, 65.3 percent of Mongolia's population was vaccinated at full dose. However, as of COVID-19 confirmed cases, Mongolia is in the top five countries in the West Pacific. This indicates that there is a lack of practice to prevention from coronavirus infection in the population.@*Goal @#This survey aims to compare the level of knowledge, attitudes, and practices of the population towards coronavirus infection with the results of the baseline survey results @*Material and Methods@#This is a cross-sectional study. A total of 1896 people aged 15-60 years old participated in the study. The survey data were collected using quantitative (questionnaire) and qualitative (observation) methods. The research methodology was approved at the Scientific Committee of the National Center for Public Health on November 9, 2021 (Protocol № 5) and the Medical Ethics Review Committee of the Ministry of Health on January 20, 2022 (Resolution №261) was issued the Ethical permission of the survey. @*Results@#Out of 14 knowledge questions that should be known about coronavirus infection, survey participants had known in an average of 8.27 ± 3.73 (95%CI: 8.12-8.43) correct answers, which was lower than the results of the baseline study. The average knowledge score of the surveyed participants of the follow-up survey (9.23±3.2, 95%CI: 9.09-9.38) was smaller than the baseline survey by 0.96 percent. 54.5 percent of surveyed participants believed that the pandemic is “very dangerous”. However, it has decreased by 25.6 percent compared to the baseline survey. Positive attitudes toward the right place at the onset of symptoms of COVID-19 and non-discrimination against infected people are more prevalent in a population with a high average knowledge score. In the baseline study, the average duration to wear a mask was 29 hours, while in the follow-up survey, it was 4.2 hours, which shows improvement in the correct behavior. @*Conclusions@#As the population’s level of education increased, the average knowledge score on the coronavirus infection has increased, and the statistically significant high of the participant with higher education levels was 8.81±3.53 (p=0.0001). In the baseline survey, 64.9 percent of the participants had an attitude toward a discriminant person infected with COVID-19, whereas it was declined by 41.9 percent in the follow-up survey. The practice of wearing masks in crowded places and outdoors were increased by 6.8 percent from the baseline survey. Compared to the baseline survey results, in the follow-up survey, practices of wearing masks in the workplace or indoor environment (73.0%) had increased.
ABSTRACT
Introduction@#During this pandemic, overcrowding in classroom caused by a lack of educational facilities and poor indoor air quality are the main causes of respiratory diseases among children and adolescents. Therefore, it is essential to measure and assess the indoor air quality where children spend extended periods of time such as school. @*Materials and methods@#This study covered four schools with old buildings and four schools with new buildings in Bayanzurkh, Sukhbaatar, Khan-Uul, Chingeltei district of Ulaanbaatar. We collected PM10 and PM2.5, carbon dioxide, air temperature, humidity, and microbiological count from chosen classrooms and compared to the MNS4585:2016 standard. SPSS-24 was used to do statistical analysis on the information gathered during the evaluation.@*Results and Discussion@#The 24-hour average PM2.5 concentration was 64.3 (95% CI: 64.1-64.5) mcg/m3, which was 4.3 times higher than the WHO guideline value and 1.3 times higher than the MNS4585:2016 standard. The 24-hour average PM10 concentration was 85.3 (95 % CI: 85.1-85.6) mcg/m3, which is 1.9 times higher than WHO guideline value. In older school buildings, the 24-hour average PM2.5 concentration was 5.6 times higher than the WHO guideline value and 1.7 times higher than the MNS4585:2016; the average PM10 concentration was 2.8 times higher than the WHO guideline value and 1.3 times higher than the MNS4585:2016. The air temperature and carbon dioxide concentration in classroom was met the MNS4585: 2016. The average relative humidity of all schools is 24.2±6.5%, which is 14-16% lower than the MNS4585: 2016. @*Conclusion@#The indoor air quality of the school in new and old buildings was similar poor, therefore a variety of steps are needed to improve it.
ABSTRACT
@#Thrombosis is a term for a blood clot occurring inside a blood vessel. R. Virchow postulated that abnormalities in blood flow, hypercoagulability of the blood, and injury to the vessel wall are causally related to thrombus formation. Many of the risk factors for deep vein thrombosis aretrauma for 9.3- 18.8%, birth for 16-17.3%, surgery for 14.3-30.3%, infection disease for 9.7-15.9%, cancer for 3.5%, heart disease for 4.6% and 6.9-11.8% of deep vein thrombosis is an indistinct cause. Pain, swelling, warmth, edema and redness in the affected leg are common symptoms.The diagnosis of deep vein thrombosis of the leg can be difficult with clinical findings and history being unreliable. The National Institute of Health and Care Excellence has evidence based recommendations on the prevention and management of a wide range of health conditions. Here: incorporation of a clinical predication score, D-dimer, and venous duplex ultrasound. The D-dimer blood test measures degraded fibrinogen, which is raised in patients with a clot. However, it cannot confirm deep vein thrombosis, as D-dimer can be raised in other conditions including malignancy, infection, pregnancy, post-surgery, inflammation, trauma, disseminated intravascular coagulopathy, and renal impairment. There are two types venous ultrasound as the first line investigation for suspected deep vein thrombosis. The aim of treatment for deep vein thrombosis are: </br> • The prevention of a thrombus progress </br> • Decrease the risk of the pulmonary embolism </br> • The reduction of the thrombus expansion or resolution.</br> • The prevention of the post thrombotic symptoms</br> • Decrease the mortality of vein thrombosis</br> Guidelines from NICE and ACCP recommended direct oral anticoagulants as first line treatment for deep vein thrombosis. Direct oral anticoagulants include direct factor Xa inhibitors apixaban, rivaroxaban, and edoxaban, and a direct thrombin inhibitor dabigatron
