Association of COVID-19 and Arterial Stiffness Assessed using Cardiovascular Index (CAVI).

Background: COVID-19 is characterized by an acute inflammatory response with the formation of endothelial dysfunction and may affect arterial stiffness. Studies of cardio-ankle vascular index in COVID-19 patients with considered cardiovascular risk factors have not been conducted.

Objective: The purpose of our study was to assess the association between cardio-ankle vascular index and COVID-19 in hospitalized patients adjusted for known cardiovascular risk factors.

[Association between cardio-ankle vascular index and markers of thrombosis in hospitalized patients COVID-19].

Aim: To evaluate the relationship between the cardio-ankle vascular index (CAVI) and the marker of procoagulant state - D-dimer in hospitalized patients with coronavirus disease 2019 (COVID-19).

Materials And Methods: This cross-sectional study involved adult patients admitted to the University hospital with clinically diagnosed or laboratory-confirmed COVID-19. We compared groups of patients with normal and elevated CAVI.

[Predictors of thromboembolic complications in patients with severe SARS-CoV-2 coronavirus infection].

Aim: To identify predictors of the development of thromboembolic complications (TECs) in patients with severe SARS-CoV-2 coronavirus infection.

Materials And Methods: A single-center observational retrospective study included 1634 patients with a confirmed diagnosis of SARS-CoV-2 coronavirus infection. The patients were divided into 2 groups depending on the availability of the feasibility study.

[Characteristics of ambient air quality in office chambers and its influence on workers' state].

Increasing health complaints of office workers are associated with exposure to indefinite risk factors. Many discussions involve ano-particles (size less than 100 nm) in air of non-industrial chambers containing contemporary office equipment. Complex study covered quality of air in offices (microclimate, organic and inorganic pollutants, dust particles).

[A survey of medical equipment displayed at the "Healthcare-2004" exhibition].

Surveyed in the paper is medical equipment displayed, November 29-December 3, 2004, in the Exhibition Hall in Krasnaya Presnya within the framework of the "Healthcare, Medical Equipment and Drugs-2004" Exhibition. The survey is made for the below categories of medical equipment: instruments and apparatuses; X-ray, neonatal, ophthalmologic and stomatological equipment; medical instruments; laboratory medical equipment; equipment for rehabilitation of patients and disabled and mobile medical equipment. A conclusion is made on that a lot of novel high-quality and high-tech medical equipment has emerged in the Russian market.
