Relationships of Thickness of Perirenal Fat with Urinary Levels of MCP-1 and NGAL in Patients with Hypertension.

Background: We conducted a study to determine the relationships between perirenal fat (PRF) thickness and urinary levels of monocyte chemoattractant protein-1 (MCP-1) and neutrophil gelatinase-associated lipocalin (NGAL) in patients with hypertension (HTN).

Methods: In 338 HTN patients (aged 63.51±12.

[Impaired hemostasis in elderly and senile patients with mesenteric thrombosis in COVID-19.].

In the treatment of coronavirus infections, it is important not only to understand the course of the disease, but also to understand what is happening in the human body, especially in the circulatory system, that is, which disorders lead to deterioration and further complications. Hemostasis disorder in COVID-19 plays an important role in the etiology and clinical manifestations of the disease. The ability to identify factors and risk groups for the development of thrombotic complications, the ability to dynamically interpret peripheral blood parameters and coagulograms, knowledge of diagnostic criteria for possible hemostasis disorders (for example, DIC syndrome, sepsis-associated coagulopathy, antiphospholipids, hemophagocytosis and hypercoagulation syndrome) are necessary to determine the indications for the test.

Relationship Between Perivascular Adipose Tissue and Cardiovascular Risk Factors: A Systematic Review and Meta-Analysis.

We conducted a systematic review and meta-analysis aimed at estimating the association between perivascular adipose tissue (PVAT) and some of the cardiovascular risk factors. A systematic search was conducted from January 1980 up to and including 2022 to identify studies that examined the relationship between PVAT and cardiovascular risk factors as obesity and its indices, hypertension, lipids, and glucose intolerance/diabetes. The Medline and Embase databases were searched using the PubMed and Scopus.

Improving the accuracy of estimates of the pulse sequence period using the methodology of complete sufficient statistics.

This paper is devoted to the synthesis of new signal processing algorithms based on the methodology of complete sufficient statistics and the possibility of using the Lehmann-Scheffe theorem. Using the example of a sequence of quasi-rectangular pulses, an approach to estimating their period was illustrated, taking into account the duty-off factor and the pulse squareness coefficient. A mathematical model was developed, on the basis of which, estimates of the potential accuracy of the methods were carried out.

[CT angiography and endovascular treatment in acute mesenteric ischemia].

Objective: To optimize the treatment strategy for acute mesenteric ischemia (AMI).
