Research and product development for Crimean-Congo haemorrhagic fever: priorities for 2024-30.

Crimean-Congo haemorrhagic fever (CCHF) is a widely distributed and potentially fatal tick-borne viral disease with no licensed specific treatments or vaccines. In 2019, WHO published an advanced draft of a research and development roadmap for CCHF that prioritised the development and deployment of the medical countermeasures most needed by CCHF-affected countries. This Personal View presents updated CCHF research and development priorities and is the product of broad consultation with a working group of 20 leading experts in 2023-24.

[Application of optical coherence tomography in the assessment of the posterior lens capsule during anti-angiogenic therapy].

Unlabelled: Intravitreal injection (IVI) of anti-angiogenic drugs is one of the most common therapeutic procedures in ophthalmology. In recent years, a new non-contact study method has been developed - anterior segment optical coherence tomography (AS-OCT), which allows the formation of three-dimensional images of the lens and provides more detailed information about its structure and morphology.

Purpose: This study uses optical coherence tomography method to analyze the risks of developing changes in the posterior lens capsule in patients after IVI of an anti-angiogenic drug.

Characteristics of self-regulation of the epidemic process of infection caused by the Epstein-Barr virus (Herpesviridae: , HHV-4).

Introduction: Among the available scientific literature, there are no publications addressing processes of self-regulation in the parasite-host population systems with reference to chronic infections, including the infection caused by the Epstein-Barr virus (EBV infection). The aim of the study is to assess manifestations of the epidemic process of chronic EBV infection through the lens of the basic tenets of the theory of self-regulation of parasitic systems.

Materials And Methods: The study was performed using data from scientific publications selected from such database sources as Scopus, Web of Science, Cochrane Library, PubMed, CyberLeninka, RSCI, etc.

National medical specialty guidelines of HIV indicator conditions in Europe lack adequate HIV testing recommendations: a systematic guideline review.

BackgroundAdequate identification and testing of people at risk for HIV is fundamental for the HIV care continuum. A key strategy to improve timely testing is HIV indicator condition (IC) guided testing.AimTo evaluate the uptake of HIV testing recommendations in HIV IC-specific guidelines in European countries.

[New opportunities for preventive anti-inflammatory therapy in the management of patients with moderate and severe COVID-19].

Unlabelled: The specific feature of new coronavirus infection (COVID-19) is high risk of hyperinflammatory response or cytokine storm development, which underly the pathogenesis of several life-threatening conditions and determine the disease outcomes. Pathophysiological features of COVID-19 justify the search of effective drugs capable to control the hyperinflammatory response.

Aim: To evaluate the efficacy and safety of Aterixen (1-[2-(1-Мethylimidazol-4-yl)-ethyl]perhydroazin-2,6-dion) for achieving clinical improvement in adult patients hospitalized with moderate and severe COVID-19.

[Opportunities for use the cascade model of medical care for people living with HIV].

The HIV cascade model can be used as an epidemiological surveillance tool and for assessing the quality of medical care for HIV-positive people. It is possible to use the model for the entire population of people living with HIV, in various socio-demographic groups, by region, years and other indicators. This article describes the features of a HIV cascade model depending on the goals for its use.

A living WHO guideline on drugs to prevent covid-19.

Clinical Question: What is the role of drugs in preventing covid-19? WHY DOES THIS MATTER?: There is widespread interest in whether drug interventions can be used for the prevention of covid-19, but there is uncertainty about which drugs, if any, are effective. The first version of this living guideline focuses on the evidence for hydroxychloroquine. Subsequent updates will cover other drugs being investigated for their role in the prevention of covid-19.

A living WHO guideline on drugs for covid-19.

Updates: This is the fourteenth version (thirteenth update) of the living guideline, replacing earlier versions (available as data supplements). New recommendations will be published as updates to this guideline.

Clinical Question: What is the role of drugs in the treatment of patients with covid-19?

Context: The evidence base for therapeutics for covid-19 is evolving with numerous randomised controlled trials (RCTs) recently completed and underway.

[The development and approbation of methodology on the basis of multiplex polymerase chain reaction in real-time to determine clinically significant micro-deletion in Y-chromosome.].

One of the prevalent genetic causes of idiopathic male sterility is related to micro-deletions in AZF locus located in Y-chromosome. In total population, rate of such micro-deletions makes up to 1:4000. however, in infertile males their rate varies from 2% to 10%.

[Hepatitis C can be cured: will hepatitis B become next?].

Chronic hepatitis B (CHB) and C (CHC) are one of the leading causes of cirrhosis and liver cancer with over a million of people dying annually from their consequences. In Russia CHB and CHC morbidity and related mortality show an upward trend. As a result of recent breakthroughs in antiviral therapeutics CHC became a curable disease.

[The results of monitoring of antigen types of rotaviruses of group A on the territory of the Russian Federation in 2011-2015.].

The data of seasonal monitoring are presented concerning antigen types of rotaviruses group A circulating on the territory of the Russian Federation in the periods of seasonal uprising of morbidity in 2011-2015. Annually, the study included from 10 to 12 subjects of the Russian Federation with annual testing from 444 to 728 samples from children aged younger than 5 years with acute infection diarrhea. In the seasons of 2011-2012, 2012-2013, 2013-2014, 2014-2015 the most prevalent [P] G types of rotaviruses correspondingly made up to: G4[P]8 -50.

[The comparison of three molecular genetic techniques for identifying major mutations in gene HFE related to development of inherent hemochromatosis.].

The three main mutations in gene HFE (C282Y, H63D, S65C) are the cause of development of 97% of cases of inherent hemochromatosis. It is known that about 85% of patients with inherent hemochromatosis are either homo-zygotic agents of mutation C282Y or carry compound-heterozygote C282Y/H63D. Therefore, the molecular genetic study intended for detection of these three mutations in gene HFE takes important place in diagnostic of inherent hemochromatosis.
