HIV-Related Atherosclerosis: State-of-the-Art-Review.

The infection caused by the Human Immunodeficiency Virus (HIV) has spread rapidly across the globe, assuming the characteristics of an epidemic in some regions. Thanks to the introduction of antiretroviral therapy into routine clinical practice, there was a considerable breakthrough in the treatment of HIV, that is now HIV is potentially well-controlled even in low-income countries. To date, HIV infection has moved from the group of life-threatening conditions to the group of chronic and well controlled ones and the quality of life and life expectancy of HIV+ people, with an undetectable viral load is closer to that of an HIV- people. However, unsolved issues still persist. For example: people living with HIV are more prone to the age-related diseases, especially atherosclerosis. For this reason, a better understanding of the mechanisms of HIV-associated destabilization of vascular homeostasis seems to be an urgent duty, that may lead to the development of new protocols, bringing the possibilities of pathogenetic therapies to a new level. The purpose of the article was to evaluate the pathological aspects of HIV-induced atherosclerosis.

Chemotherapy, hypothyroidism and oral dysbiosis as a novel risk factor of cardiovascular pathology development.

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in the population, as well as the economic burden of the health care system. Currently, CVDs account for more than 17.6 million deaths a year and are projected to exceed 23.6 million by 2030. Unstable atheroma, and its rupture, underlies the pathology of most cardiovascular complications, particularly acute coronary syndrome, mortality from which, compared with other CV events, remains the leading one. Despite numerous efforts by WHO, national health systems, and medical authorities, the incidence and mortality from cardiovascular events remain critically high. Thus, the search for new risk factors for the development of CV pathology looks very relevant. Our working group decided to amalgamate our research data, which reflects the study of modern risk factors from the Armenian, Russian, Georgian, and Iranian medical schools. In particular, the aspects of cardiotoxic effects of chemotherapy, hypothyroidism, and oral dysbiosis are discussed.

The Keystones of Right Ventricular Arrhythmogenic Cardiomyopathy-Induced Morphological Disarrangement.

Arrhythmogenic right ventricular cardiomyopathy is an urgent problem of modern cardiology. This myocardial remodeling manifests various desmosomopathies, channelopathies, and other mutations resulting in a violation of the coordinated heart work, particularly the myocardium. The incidence of this cardiomyopathy is not significant. Still, it is worth noting that athletes are at an increased risk of developing this disease, emphasizing the importance of studying this topic and its relevance from cardiologists and sports physicians. Moreover, the clinical pattern of this disease is heterogeneous. This pathology requires strengthening control and attention of medical personnel and constant improvement and optimization of diagnostic methods and treatment protocols. In this article, the pathophysiological mechanisms, molecular genetic aspects, and the dynamics of morphofunctional changes are represented in detail. Understanding the mechanisms of etiopathogenesis and the features of morphological changes observed in this cardiomyopathy and its more detailed study is fundamental in developing modern treatment methods to improve patients' quality and life expectancy.

Human papillomavirus infection in women with and without cervical cancer in Tbilisi, Georgia.

BACKGROUND: No accurate estimates of cervical cancer incidence or mortality currently exist in Georgia. Nor are there any data on the population-based prevalence of high-risk (HR) human papillomavirus (HPV) infection, which, in the absence of good-quality screening, is known to correlate with cervical cancer incidence. METHODS: We obtained cervical cell specimens from 1309 women aged 18-59 years from the general population of Tbilisi, and also from 91 locally diagnosed invasive cervical cancers (ICC). DNA of 44 HPV types was tested for using a GP5+/6+-based PCR assay. RESULTS: In the general population (of whom 2% reported a previous Pap smear) HPV prevalence was 13.5% (95% CI: 11.6-15.9), being highest in women aged 25-34 years (18.7%) and falling to between 8.6% and 9.5% for all age groups above 34 years. HR HPV prevalence was 8.6% overall, being 6.8% and 38.9% among women with normal and abnormal cytology, respectively. HPV45 (1.6%) was the most common type in women with normal cytology, whereas HPV16 predominated among women with cervical abnormalities (including 7 of 10 histologically confirmed cervical intraepithelial neoplasia 2/3) and among ICC (57.6%). The next most common types in ICC in Georgia were HPV45 and 18 (13.2 and 11.0%, respectively). CONCLUSIONS: We report a relatively high burden of HPV infection in Tbilisi, Georgia. Improving cervical cancer prevention, through screening and/or HPV vaccination, is an important public health issue in Georgia, where 70% of ICC are theoretically preventable by HPV16/18 vaccines.
