Structural analysis of prognostic diagnostics of cardiovascular system adaptive capacity and assessment of psycho physiological resistance to stressоgenic cognitive loads.

OBJECTIVE: Aim: To conduct a structural analysis of cardiological signs of adaptation to stressogenic cognitive loads by identifying factor features of correlations between heart rate variability (HRV) and coping-testing data indicators. PATIENTS AND METHODS: Materials and Methods: 43 people aged 19.7±1.8 years (23 boys and 20 girls) were monitored for their HRV. Methods included DC-06000 portable ECG recorder, 3X series "badge" type (single channel) and COPE Test. The study process includes four stages. RESULTS: Results: As a result of further factor correlation analysis, it was revealed that Factor 1 "HRV Stress Indicators" has a negative correlation (p<0.05) of "moderate" strength ρs= -0.363 with Factor 2 "Strategies to avoid problems and stresses" and a positive correlation of "weak" strength ρs=0.167 with Factor 3 "Psychoemotional Indicators". If two factors correlate with each other, it indicates they are related and can interact, which is important for adequate interpretation of the results of factor analysis. CONCLUSION: Conclusions: Structural analysis of the complex of cardiological signs of adaptivity to stressogenic cognitive loads and coping-testing data revealed the existence of three correlated factors: Factor 1 "HRV Stress Scores", Factor 2 "Strategies to avoid problems and stress", Factor 3 "Psychoemotional indicators". The revealed negative correlation of Factors 1 and 2 may indicate that in case the impact of Factor 2 "Strategies to avoid problems and stress" increases, the intensity of Factor 1 "HRV Stress Scores" (i.e., stress signs according to the indicators of heart rate variability) may decrease.

Foodborne Botulism in Ukraine from 1955 to 2018.

We aim to identify possible biological, social, and economic factors that could influence the prevalence of foodborne botulism (FB). The objective of this article is to assess epidemiological peculiarities of FB in Ukraine from 1955 to 2018 using national epidemiological surveillance data. This article presents an epidemiological descriptive population-based study of the epidemiology of FB using correlation analysis. From 1955 to 2018, 8614 cases of botulism were recorded in Ukraine causing 659 deaths. The distribution of types of botulism toxins is represented by type A (7.97%), B (59.64%), suspected as C (0.56%), E (25.47%), others (5.33%), and unidentified (1.04%). From 1990 to 2015, the rate correlation between Human Development Index (HDI) and incidence of botulism was -0.75 ± 0.20. Homemade canned meat and fish continue to be the leading causes of botulism in Ukraine. Cases related to commercial food were rare or absent, but in recent years (2017-2018), their percentage has increased to 32.56%. The HDI and botulism have an inverse mathematical correlation and predictable logical relationship: with an HDI increase, the incidence of FB decreased. In general, food botulism in Ukraine is related to traditional socioeconomic factors related to cultural food habits. In the face of declining living standards and uncertainty that food products will be physically or economically available, homemade preservation increases. Home food preservation is a major cause of botulism in Ukraine. The elimination of FB is possible in Ukraine only with the complete cessation of home canning and state control over the manufacture and sale of commercial canned products.

Evolution of Monitoring and Evaluation of AIDS Response in Ukraine: Laying the Groundwork for Evidence-Based Health Care.

Once facing the most severe HIV epidemic in Eastern Europe, Ukraine has built an elaborate Monitoring and Evaluation (M&E) system to track the response to AIDS. This system was developed using recommendations and input from multiple international expert organizations and donors and, at the current stage, serves as a best practice model in many areas. The present paper aims to provide a comprehensive overview of the evolution of the M&E system in Ukraine since its inception. Notable achievements and challenges are described and illustrated by epidemiological data and the recommendations for future development are discussed. Unique experiences and advances in M&E in Ukraine may be useful to other countries facing similar epidemiological, structural or methodological issues.

Treatment of opioid use disorder in Ukraine during the first year of the Russia-Ukraine war: Lessons learned from the crisis.

The Russian invasion of Ukraine in February 2022 caused major disruptions of societal functions, including health care. Patients receiving medications for opioid use disorder (MOUD) depend on receiving daily treatment and face a risk of withdrawal in case of medication supply disruption. MOUD are banned in Russia, making treatment continuation impossible in temporarily occupied areas. In this paper, we review the situation with MOUD delivery in Ukraine during the first year of the Russia-Ukraine war. Legislative changes and mobilization of efforts in the time of crisis ensured treatment continuation for thousands of patients. In areas controlled by Ukraine, most patients were receiving take-home doses for up to 30 days, some experienced temporary dosing reductions. Programs in temporarily occupied regions were shut down likely leading to abrupt withdrawal among many patients. At least 10% of patients have been internally displaced. One year into the war, the number of MOUD patients in governmental clinics of Ukraine increased by 17%, and the data suggest that the coverage of private clinics has also increased. But the risks for program stability remain high as the current medication supply relies on one manufacturing facility. Using lessons learned from the crisis, we provide recommendations for future response to minimize the risks of major adverse outcomes among patients treated for opioid use disorder.

Cross-sectional HIV and HCV cascades of care across the regions of Ukraine between 2019 and 2020: findings from the CARE cohort.

INTRODUCTION: Eastern Europe is facing major HIV and hepatitis C (HCV) epidemics, with many people living with HIV (PLHIV) and HIV/HCV coinfection living in Ukraine. Despite the previous progress towards care quality improvement, the ongoing war in Ukraine is disrupting HIV and HCV care. METHODS: We described an HIV cascade of care (CoC) in PLHIV from two clinical sites and an HCV CoC for anti-HCV-positive PLHIV from six sites in Ukraine, enrolled in the CARE cohort between 1 January 2019 and 1 June 2020. The cross-sectional HIV CoC and HCV CoC are described at study enrolment. RESULTS: Of 1028 PLHIV, 1014 (98.6%, 95% confidence interval [CI] 97.7-99.3) were on antiretroviral therapy (ART), and 876 (86.4% of those on ART, 95% CI 84.1-88.4) were virologically suppressed. Of 894 participants on ART >6 months, 90.8% (95% CI 88.7-92.6) were virologically suppressed (HIV-RNA <200 copies/ml). Of 2040 anti-HCV-positive PLHIV, 417 (20.4%, 95% CI 18.7-22.3) were ever tested for HCV-RNA prior to enrolment, ranging from 4.9% to 54.4% across sites, and 13.5% were currently HCV-RNA positive. One hundred and eighteen persons (7.3% of ever chronically infected) had received HCV treatment, and 25 persons (1.6% of ever chronically infected) were cured, with variations across sites (0%-7.5%). The site diagnosing 54.4% of people with chronic HCV was the only one providing free RNA testing for all anti-HCV-positive persons, while the intra-country differences in treatment coverage were driven by the number of available direct-acting antiviral (DAA) courses. CONCLUSIONS: Over 98% of PLHIV in care in both CARE sites in Ukraine were receiving ART, and the target of 90% virally suppressed was achieved in persons >6 months on ART. Only one of six HIV/HCV study sites tested over 50% anti-HCV-positive PLHIV for HCV-RNA and treated over 25% of eligible persons. While free HCV-RNA testing and DAA treatment are paramount to achieving HCV elimination targets, they remained a challenge in Ukraine in 2019-2020. The extent of the HIV and HCV care disruption during the war will be further assessed in the CARE cohort and compared with the pre-war findings.
