Such measures have been examined profoundly both by Russian and foreign researchers all over the world. The pandemic of this new coronavirus infection has shown that sanitary and preventive measures are among the most significant components in fighting against it, along with anti-epidemic activities and treatment measures, development of new vaccines and medications. All over the world, many countries introduce several sanitary-epidemiological and social measures to prevent spreading of the SARS-CoV-2 virus that causes COVID-19. The review dwells on the results obtained by investigating effectiveness of non-specific prevention of the new coronavirus infection in different countries. As illustrated in the review, it was important to introduce restrictive measures with their major aim being to prevent (or limit) the infection transmission by airborne droplets or through household contacts. Researchers performed hygienic assessment of personal protective equipment used for protection of respiratory organs and hand skin and developed recommendations on its safe and effective use and utilization. Self-isolation as a restrictive measure to prevent the COVID-19 pandemic from spreading was a temporary one. Nevertheless, during the pandemic peak billions of people all over the world had to remain at home after the strict self-isolation had been introduced. The review provides some data on estimating the level of commitment among population to follow recommendations on limiting the infection spread in Russia and abroad. In Russia, there is a reliable and effective state infra-structure of public healthcare. It made it possible to keep the pandemic situation under control starting from the early days when cases of pneumonia with unspecified etiology were reported in December 2019 and the first COVID-19 cases were registered in the country. Several measures were introduced including administrative, organizational, technical and sanitary-hygienic ones. However, it was a challenging task to create a relevant response to the COVID-19 pandemic that the public healthcare system in Russia had to tackle.","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43977382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such devices should provide an opportunity to analyze component and disperse structures of the solid component in ambient air pollution operatively and in real time. In future, they will replace labor-consuming sampling and separate identification of fraction structure and chemical composition of dusts. The aim of this study was to develop and test new methodical, procedural and instrumental approaches to monitoring of solid particles in ambient air. We suggest a hardware and software complex that implements a two-stage scheme for identifying solid particles sampled in ambient air according to the from-coarse-to-fine principle. The first stage involves identifying the total concentration of solid particles by laser diffraction. Microphotographs are taken with iMicro Q2 mini portable microscope with magnification x800. The microscope lens is connected to a camera, which is linked to nVidia Jetson Nano micro PC. The micro PC classifies particles, identifies their contours by using a neural network and deals with image segmentation. The second stage relies on using computer vision that makes it possible to automate routine recognition of particle images created by the microscope in order to calculate levels of different substances in a sample. All the data are analyzed by the second neural network that performs preset calculations in accordance with mathematical logic (model). The network is trained using a library that contains attributed microphotographs of dusts with different qualitative and disperse structures. The algorithm has been tested with some promising results. Identified disperse structures and chemical composition of dusts turn out to be quite similar to those identified by conventional approaches and measurement methods. The method has been shown to offer wide opportunities to identify dust composition and structure, to create dust pollution profiles, and to estimate a contribution made by a specific source to overall pollution. The study results ensure more correct and precise health risk assessment under exposure to dusts in ambient air.","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49251920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to comparatively analyze risk factors related to the educational process in different schools and to develop a new approach to objective assessment of combined exposure to environmental factors and factors related to the educational process and its influence on schoolchildren’s health. The study focused on the following research objects: 1) five different secondary schools, the test ones providing profound educational programs and the reference ones being ordinary secondary schools with the same or lower levels of pollution in environmental objects; 2) quality of components in the school environment (organization of the educational process, quality of meals provided by school, quality of ambient air on a school territory and inside a school, quality of drinking water, socioeconomic conditions); 3) health of 756 schoolchildren. The study was conducted by using sanitary-epidemiological, sanitary-hygienic and sociological methods; clinical and laboratory examinations; chemical analytical tests. Fuzzy logic was applied to estimate combined influence exerted by factors related to the educational process and environmental factors. We established several determinants of negative effects produced by the educational process on schoolchildren’s health. They included elevated intensity and monotony of educational and intellectual loads, shorter breaks between classes and recovery index deficiency. Diet-related factors included excess consumption of fats and carbohydrates, overall caloric contents being too high, protein and micronutrient deficiency. Chemical factors were elevated levels of metals, aromatic hydrocarbons, aldehydes, and chlorinated organic compounds in biological media. Risk-inducing factors of schoolchildren, regardless of a school and age, include organization of the educational process (Ipj = 0.45–0.58) and school meals (Ipj = 0.41–0.54); the group potential hazard index for these factors reached its peak values in primary school (Ipj = 0.49–0.58 and Ipj = 0.46–0.54). The maximum value of the integral potential hazard index (Ipdk = 0.41–0.46) caused by combined exposure to factors related to the educational process and environmental factors, regardless of a school type, was detected in senior schoolchildren in school with profound studies of natural sciences (Ipdk = 0.41); the minimum value was detected in a military school (Ipdk = 0.33).","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45405995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computational fluid dynamics and mathematical modeling can be used to perform quantitative predictive assessments of hemodynamic properties in varied conditions. This article addresses the development of a coupled 0D–3D model of blood flow in newborns to predict risks of complications after surgery. The 0D-model of systemic circulations is created by using the analogy between the blood flow in vessels and the flow of current through an electric circuit. A shunted section of the aorta and pulmonary artery is replaced with a 3D-model with two-way fluid-solid interaction (FSI).A section in a vessel with the aortic valve is examined in a separate 3D-model. Three-dimensional geometry is based on real CT-scans of a patient. The algorithm for coupling models of different levels relies on meeting the condition that pressures and volumetric blood flows are equal at the interaction boundary. We have developed an algorithm for identifying personal parameters from the results obtained by solving an optimization problem. Computational experiments with different individual geometry of the aorta and aortic valve made it possible to analyze blood flow velocities, near-wall stresses, flows, and valve deformations. Observable near-wall stresses can be considered risk factors that could cause calcification on valve leaflets and other valve diseases. Computational solutions in the “aorta – shunt – pulmonary artery” 3D-system allowed obtaining spatial distributions of velocities, pressures, near-wall stresses and other parameters that are significant in respect to probable pathology development. The developed approaches are primarily relevant for decision-making in surgical practice to predict risks of postoperative complications. In future, our plans are to develop the model so that it covers also saturation and oxygen exchange. This is necessary for assessing whether oxygen supply to the lungs is adequate.","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46188532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Absence of substantiated preventive actions aimed at minimizing ammonia emissions hinders commissioning of new residential buildings and may create an unfavorable sanitary-epidemiological situation with obvious olfactory-reflex and irritating effects on public health. The aim of this study was to develop a scientifically grounded method to predict when ammonia concentrations emitted from concrete constructions would reach their permissible levels in air inside contaminated premises in newly constructed buildings. Ammonia emissions were estimated based on data of laboratory tests that involved analyzing indoor air samples taken in Saint Petersburg and the Leningrad region. Indoor air was analyzed in 4 newly constructed residential buildings (165 premises, 57 test protocols, 893 air samples tested to identify ammonia in them). Relationships between changes in ammonia concentrations and ventilation time were obtained by using regression analysis (regression equation, least square method). To establish reproducibility of the results and a possibility to compare them, we tested variances for homogeneity by using Fisher criterion. Sampled populations were compared with Student’s t-test in case the data fitted to a normal distribution (Kolmogorov – Smirnov test, Shapiro – Wilks test). Critical significance was taken at 0.05 in all the statistical comparisons. We have developed a method for predicting when ammonia concentrations that occurred in indoor air inside newly constructed buildings due to multi-day emissions from building materials would reach their permissible levels. The method involves multi-day measurements (y, mg/m3) of ammonia concentrations sequentially in each premise inside a newly constructed building on any day of measurements during the time period t; building up relationships between averaged ammonia concentrations (yav, mg/m3) and a time moment t; mathematical analysis of the obtained relationships by parameterization and statistical analysis of the obtained kinetic parameters.","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49078503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By conducting a survey, we obtained data on use of mobile electronic devices by 1218 schoolchildren and students both in their educational and spare time activities and created a profile of a work and rest routine when working with mobile electronic devices. 943 students and schoolchildren were examined by an ophthalmologist. Next, issues related to hygienic education were integrated into the training program for medical students at the Hygiene Department of the Pirogov Russian National Research Medical University. The emphasis was on creating a safe routine of using mobile electronic devices. Schoolchildren and students who adhered to a healthy work and rest routine when working with mobile electronic devices complained about health disorders authentically less frequently (p ≤ 0.05).We established a statistically significant relative risk for visual acuity if schoolchildren and students did not pursue a safe routine of using mobile electronic devices. Its level was RR = 3.07 (95 % CI =1.88–5.03). By the end of hygienic studies with their focus on creating a safe routine of using mobile electronic devices, medical students had an authentic (p ≤ 0.05) increase in visual acuity due to decline in such states as routine accommodative excess and pre-myopia. Work and rest routines accepted by children, adolescents and youth when they use mobile electronic devices are a manageable risk factor of health disorders in these population groups.

The test group included 33 children with allergic diseases; the reference group consisted of 40 relatively healthy children. CD-markers were identified with flow cytometry.

The assessment relied on data obtained at monitoring posts of RSE “Kazhydromet” between 2018 and 2021. We identified six carcinogens in the analyzed area that created unacceptable public health risks. High non-carcinogenic risks were typically caused by exposure to particulate matter (dust), РМ2.5 and РМ10, sulfur dioxide and sulfuric acid. Our assessment of non-accidental mortality risks caused by exposure to РМ2.5 in ambient air established unacceptable relative risks (RR: 1.27–1.78), individual risks of non-accidental (1.5–2.1•10-3) and cardiopulmonary mortality (between 8.3•10-4 and 1.0•10-3). Unfavorable meteorological factors and geographic location can promote high levels of ambient air pollution and created aerogenic health risks for people living in the analyzed industrial area. The established risks require developing and implementing scheduled health-improving activities aimed at raising quality of the environment.","PeriodicalId":12945,"journal":{"name":"Health Risk Analysis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43358407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
