Development of method approaches to the use of regression models for assessment of health effects of socio-economic risk factors in the system of socio-hygienic monitoring (experience of the Sverdlovsk region)

The analysis of socio-hygienic monitoring data showed statistically significant correlations between the mortality in working-age population and socio-economic indices (modern conveniences in homes, availability of medical aid, the portion of pensioners, and the level of unemployment) and also between their increases with account for the time lag. The highest (by module) coefficients of correlation between the increase in socio-econom ic risk factors and the change in the working-age mortality rate were found with the time lag of 1 year. For a more adequate decision making related to effects of socio-economic factors indicator rates in the sphere of securing sanitary and epidemiologic welfare of the population were identified.Проведенный анализ данных социально-гигиенического мониторинга показал наличие статистически значимых корреляционных связей между смертностью населения в трудоспособном возрасте и социально-экономическими показателями (степень благоустройства жилья, обеспеченность врачами, доля пенсионеров и уровень безработицы), а также между их приращениями с учетом временных сдвигов. Наибольшие (по модулю) коэффициенты корреляции между приращениями социально-экономических факторов риска и изменением показателя смертности в трудоспособном возрасте отмечены при временном сдвиге 1 год. Выявлены индикаторные показатели в сфере обеспечения санитарно-эпидемиологического благополучия населения для более адекватного принятия управленческих решений в связи с воздействием социально-экономических факторов

Risk of Venous Thromboembolic Complications in Patients with Atrial Fibrillation: a Systematic Review and Meta-analysis

Aim: The aim of this meta-analysis and systematic review was to evaluate the possible connection between AF and VTE.Material and methods. Atrial fibrillation (AF) and atrial flutter (AFL) contribute to intra-atrial blood stasis which leads to thrombus formation with its embolization. There is some evidence that AF can be a risk factor for deep vein thrombosis (DVT) and pulmonary embolism (PE). The following databases were searched: PubMed (MEDLINE), EMBASE, Google Scholar, the Cochrane Central Register of Controlled Trials. The time frame for conducting a systematic literature search ranged from January 1, 1990 to November 1, 2021. The diagnosis of atrial fibrillation had to be confirmed by using ECG. The diagnosis of VTE could be made with Doppler imaging, ventilation/perfusion scan, CT angiography, venography, angiography or autopsy. Only the three studies with 102192 patients meeting the requirement were included in the meta-analysis.Results. The prevalence of DVT and PE were assessed using incidence rate ratios (IRR) method of the inverse variance random effects model and its 95% confidence interval (CI). The significant association between atrial fibrillation and pulmonary embolism was found (IRR, 4.18 95% Cl 1.958.98). Also there is obvious association between DVT and AF (IRR, 2.97 95% Cl 2.18-4.03).Conclusion. It can be concluded that the increased risk of developing VTE is associatedwith concomitant AF

Peculiar Aspects of Epidemiological Situation on Crimean Hemorrhagic Fever in the Russian Federation in 2011

Outlined is the analysis of epidemiological and epizootiological situation on Crimean hemorrhagic fever (CHF) in the south of the Russian Federation in 2011. Discussed are the causes of nosocomial outbreak of CHF at the Salsk district central hospital, the Rostov Region. Prognostication on CHF situation for 2012 is made based on the epizootiological monitoring

Microwave-Assisted Solution Synthesis of Metastable Intergrowth of AgInS2 Polymorphs

The intergrowth of stable and metastable AgInS2 polymorphs was synthesized using a microwave-assisted synthesis. The samples were synthesized in water and in a deep eutectic solvent (DES) consisting of choline chloride and thiourea. An increase in the metal precursor concentration improved the crystallinity of the synthesized samples and affected the particle size. AgInS2 cannot be synthesized from crystalline binary Ag2S or In2S3 via this route. The solution synthesis reported here results in the intergrowth of the thermodynamically stable polymorph (space group I4¯ 2d, chalcopyrite structure) and the high-temperature polymorph (space group Pna21, wurtzite-like structure) that is metastable at room temperature. A scanning transmission microscopy (STEM) study revealed the intergrowth of tetragonal and orthorhombic polymorphs in a single particle and unambiguously established that the long-thought hexagonal wurtzite polymorph has pseudo-hexagonal symmetry and is best described with the orthorhombic unit cell. The solution-synthesized AgInS2 polymorphs intergrowth has slightly lower bandgap values in the range of 1.73 eV–1.91 eV compared to the previously reported values for tetragonal I4¯ 2d (1.86 eV) and orthorhombic Pna21 (1.98 eV) polymorphs.This article is published as Adeyemi, Adedoyin N., Rae Ann Earnest, Tori Cox, Oleg I.

Epidemiological Situation on Natural Focal Viral Infections in the Territory of the Stavropol Region

Landscape-geographical and climatic peculiarities of the Stavropol Region, high abundance of mosquito and ticks, the diversity of wild mammal and bird species, developed agriculture and infrastructure create favorable conditions for circulation of arboviruses and hantaviruses, emergence of cases of viral infections, which sometimes cause serious epidemic complications. CHF natural focus actively functions in the territory of the Stavropol Region at present. Detected is presence of West Nile fever, tick-born encephalitis, Batai fever agents and specific antibodies, as well as hemorrhagic fever with renal syndrome agent

Deep Eutectic Solvent Synthesis of Perovskite Electrocatalysts for Water Oxidation

Oxide perovskites have attracted great interest as materials for energy conversion due to their stability and structural tunability. La-based perovskites of 3d-transition metals have demonstrated excellent activities as electrocatalysts in water oxidation. Herein, we report the synthesis route to La-based perovskites using an environmentally friendly deep eutectic solvent (DES) consisting of choline chloride and malonic acid. The DES route affords phase-pure crystalline materials on a gram scale and results in perovskites with high electrocatalytic activity for oxygen evolution reaction. A convenient, fast, and scalable synthesis proceeds via assisted metathesis at a lower temperature as compared to traditional solid-state methods. Among LaCoO3, LaMn0.5Ni0.5O3, and LaMnO3 perovskites prepared via the DES route, LaCoO3 was established to be the best-performing electrocatalyst for water oxidation in alkaline medium at 0.25 mg cm–2 mass loading. LaCoO3 exhibits current densities of 10, 50, and 100 mA cm–2 at respective overpotentials of approximately 390, 430, and 470 mV, respectively, and features a Tafel slope of 55.8 mV dec–1. The high activity of LaCoO3 as compared to the other prepared perovskites is attributed to the high concentration of oxygen vacancies in the LaCoO3 lattice, as observed by high-resolution transmission electron microscopy. An intrinsically high concentration of O vacancies in the LaCoO3 synthesized via the DES route is ascribed to the reducing atmosphere attained upon thermal decomposition of the DES components. These findings will contribute to the preparation of highly active perovskites for various energy applications.This article is published as Hong, Sangki, Aida M. Díez, Adedoyin N.
