Climate Influence on Blood Pressure Rhythms and Left Ventricular Parameters in Hypertensive Patients: Comparative Study.

Background: Hypertension is a prevalent condition that significantly impacts cardiovascular health. The rhythmicity of arterial blood pressure (BP) can vary based on climatic conditions, potentially influencing the severity and outcomes of hypertensive complications. The study aims to assess the characteristics of arterial blood pressure rhythmicity in hypertensive patients and their influence on the structural parameters of the left ventricle of the heart in both temperate and subarctic regions of Russia.

[Clinical and morphological characteristics of lung sequestration].

Objective: To study the clinical and morphological manifestations of lung sequestration.

Material And Methods: Surgical material (lung tissue) of 18 patients (2017-2021) and 8 archival observations (1972-1994) of confirmed lung sequestration were examined. Histological staining (hematoxylin and eosin, Schiff reagent, Ziehl-Neelsen, picrofuchsin according to Van Gieson) and immunohistochemical reactions with antibodies to SMA, TTF1, CK5/6 (DAKO) were performed.

The issue of vaccine refusal: study of risky behaviour.

Background: The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups.

Methods: A survey was conducted amongst three high‑risk groups in years 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2) and 433 students (group 3).

The issue of vaccine refusal: the study of a risky behavior.

Purpose: Influenza is the most common seasonal infectious disease that causes permanent social, economic, and medical problems worldwide. Therefore, the most effective way to prevent influenza is through vaccines. The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups.
