Pharmaceutical potential of red clover (Trifolium pratense L.)
Abstract
BACKGROUND: The development and approval of plant-derived branded drugs have emerged as promising areas in the pharmaceutical industry. Red clover (Trifolium pratense L.) has historically been used in folk medicine as a source of biologically active substances with medicinal properties. Red clover is a widely abundant and easily extractable plant, offering a high cost-efficiency. Therefore, red clover extracts may reasonably be proposed as a potential source for the development of new promising pharmaceuticals.
AIM: To evaluate the pharmaceutical potential of biologically active extracts of red clover.
MATERIAL AND METHODS: The study involved a systematic review of scientific literature sourced from the PubMed biomedical database. A review of the literature was conducted over a 50-year period. The preliminary keyword-based search yielded 1,194 articles. Of these, 41 publications were selected for further analysis, as they were deemed to be the most relevant to the subject matter of the study.
RESULTS: Red clover (Trifolium pratense L.) is a widespread, perennial officinal herb. Herbal extracts have been demonstrated to have a wide range of biological activities. The majority of these compounds are isoflavones, flavonoids, saponins, clovamides, and phenolic acids. Isoflavones are phytoestrogens that have demonstrated efficacy in the treatment of female reproductive system diseases. Moreover, scientific studies have evidenced their anti-inflammatory and reparative potential, along with efficacy in the prevention and treatment of metabolic disorders. Flavonoids, saponins, clovamides, and phenolic acids have been documented to produce antioxidant and antiplatelet effects.
CONCLUSION: Among biologically active extracts of red clover, isoflavones have been identified as the most promising for pharmacological applications. Furthermore, there are other compounds with a well-documented therapeutic potential that require further investigation to develop novel branded drugs.

Analysis of global terrorism in 1970–2020
Abstract
BACKGROUND: In recent years, there has been a notable increase in the number of armed conflicts, terrorist attacks (TAs), and related medical and biological consequences.
AIM: To analyze global terrorism statistics covering the period from 1970 through 2020 to enhance the effectiveness of anti-terrorism activities.
MATERIAL AND METHODS: The study analyzes the available data from the Global Terrorism Database (GTD). The individual risks of TA-related deaths and injuries were calculated per one million people. The data are expressed as means or medians with upper and lower quartiles (Me [Q25; Q75]).
RESULTS: Over the 51-year period (1970–2020), approximately 215,000 TAs were recorded globally, resulting in 498,500 fatalities and 597,800 injuries. The mean annual terrorism statistic was 4,200 TAs (3,100 [1,400; 4,800]), with 9,600 deaths (7,100 [4,400; 10,300]) and 11,700 injuries (7,600 [3,600; 15,900]). The TAs were analyzed based on the following criteria: geographical region, type, weapons, and objectives (targets). For the global population, as calculated excluding terrorists, the estimated individual risk yielded a value of 1.25×10–6 (1.16 [0.64; 1.73]×10–6) deaths/(person×year) and 1.71×10–6 (1.32 [0.80; 2.28]×10–6) injuries/(person×year). It is noteworthy that the risk is increasing.
CONCLUSION: The most common types of weapons used in TAs were explosives and firearms, which made it extremely challenging to prevent deaths and injuries. While approximately half of TAs have no medical or biological consequences, the probability of dying in a terrorist attack remains high. As terrorism cannot be completely eradicated, it is crucial to implement effective anti-terrorism measures to minimize its impact.



Features of blood microcirculation across different age groups in relation to urban ecosystem conditions
Abstract
BACKGROUND: Understanding adverse effects of environmental factors, including those associated with urbanization and high population density, are important for development of public health protection measures. The hemodynamics of the microcirculatory system plays a significant role in maintaining tissue homeostasis, with morphofunctional characteristics often present in most cases of diseases. However, there remains a lack of comprehensive research on the aging process and the effects of residing in different urban settings on microcirculation dynamics.
AIM: To study the changes in the microcirculatory system across different age groups, depending on the state of urban ecosystems, including a megalopolis and a small tourist city without significant industrial activity.
MATERIAL AND METHODS: The study involved volunteers from the industrial megalopolis of Nizhny Novgorod and the city of Semenov, a small tourist town without significant industrial activity. Volunteers from different areas, varying in terms of human activity and environmental conditions, were divided into three age groups: group 1: 18–44 years old, group 2: 45–59 years old, and group 3: 60–74 years old. Microcirculation was measured by laser Doppler flowmetry (LDF) using a laser capillary blood flow analyzer "LAZMA ST" (NPP LAZMA LLC, Russia). The amplitude-frequency characteristics were evaluated with a wavelet analysis of blood flow oscillations.
RESULTS: A comparison of the amplitude-frequency characteristics (frequency response) of microcirculation between the 1st group of a megalopolis and a small tourist city with minimal industrial activity did not reveal any significant differences. However, upon further analysis of the amplitude-frequency spectrum of groups 2 and 3, changes in the reactivity of microcirculatory structures were observed, depending on age and urban environment. Inter-group differences based on urban ecosystems were identified through variations in endothelial rhythm amplitudes (Ae), neurogenic rhythm (An), myogenic oscillations (Am), and heart rate amplitude (Ah). The megalopolis group exhibited a decrease in An, Am, and Ah, along with an increase in Ae in groups 2 and 3. In contrast, the small city population showed a decrease in Ae, An, and As in group 2, followed by an increase in Ae, An, Am in group 3, and a further decrease in As compared to age groups 1 and 2. Furthermore, the indicator reflecting the power of blood flow into the microcirculatory bed decreased in the 3rd age group of the megalopolis.
CONCLUSION: The analysis of microcirculation using the LDF method allows to identify the involvement of various mechanisms regulating microcirculation, depending on the condition of the agro-ecosystem and the presence of risk factors that reduce adaptive capacity with age and living in a megalopolis. The findings from this study can be used to develop measures to prevent tissue perfusion insufficiency in different urban environments.



Actual prevalence of obesity and its correlation with medical and social factors among the employed population in the Saratov region
Abstract
BACKGROUND: Obesity is a common, multifactorial disease that significantly contributes to other chronic noncommunicable diseases, which are the leading causes of premature mortality worldwide. The observed increase in the prevalence of obesity is attributable to a wide range of behavioral, medical, social, and biological factors.
AIM: To assess of the actual prevalence of obesity among the employed population in the Saratov region and its correlation with medical and social factors.
MATERIAL AND METHODS: A cross-sectional study was conducted to assess the prevalence of obesity among 3,721 employees, evaluating a range of medical and social factors, including sex, age, education, place of residence, physical activity, and risk factors for metabolic syndrome. The R programming language was used for statistical analysis. A probit regression model was created to determine the probability of obesity based on the presence or absence of specific factors.
RESULTS: A univariate analysis demonstrated a correlation between obesity and a number of medical and social factors, including sex, age, education, labor intensity, physical activity, and the risk factors for metabolic syndrome. A regression analysis revealed a lower prevalence of obesity among males engaged in physically demanding work and among females with a university degree. A regression analysis demonstrated a positive correlation between obesity and the markers of cardiometabolic risk, including an above-normal waist circumference, hyperglycemia, low HDL, and hypertension, in the overall study population and male participants. In the female cohort, the analysis identified an above-normal waist circumference and hypertension as correlates of obesity. The notable finding was that triglyceride levels were not associated with obesity in any of the groups. The study had several limitations, including those related to region (the Saratov region), age (working-age population), and occupational status (employed population).
CONCLUSION: A representative sample of the employed population in the Saratov region was used to establish the obesity prevalence patterns among males and females in various age groups. Additionally, the study identified the major medical and social risk factors for obesity. It is essential to consider the probability of a high body fat percentage among individuals with normal body weight and those who are overweight to prevent and mitigate cardiometabolic risks. The findings of this study are potentially beneficial for the creation of preventative strategies integrated into employee wellness initiatives focused on maintaining the wellbeing, quality of life and professional longevity of the employed population.



Migration-related risk of psychosomatic disorders in socially healthy young adults who experience significant emotional and mental loads
Abstract
BACKGROUND: There is a paucity of scientific literature investigating the potential correlation between the geographical distance between an individual's initial and final place of residence and the risk of psychosomatic disorders in those experiencing significant emotional and mental loads.
AIM: To develop an integrative index for the assessment of the risk of psychosomatic disorders in young adults who are changing their place of residence.
MATERIAL AND METHODS: The study included medical students at the Volgograd State Medical University (97 males and 99 females between the ages of 18 and 22 years). The proportion of non-residents was 44% (45 respondents) of males and 60% (61 respondents) of females. The cross-sectional study was performed during the spring examinations in June 2023, i.e., at 9 months after the start of the academic year and change of residence by non-resident students. The symptoms of psychosomatic disorders were identified using the Gurvich Psychological Adaptation Test. The Giessen Subjective Complaints List and the Hospital Anxiety and Depression Scale (HADS) were used to report somatic symptoms and anxiety/depression, respectively. The severity of suicidal ideation was assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS). The geographical distance (km) between an individual's initial and final place of residence distances was calculated.
RESULTS: A direct, statistically significant correlation has been identified between the severity of psychosomatic disorders and the distance travelled by young adults migrating from their place of previous residence to their final destination. The potential for migration-related risk of medical conditions is classified into four categories based on geographical distance intervals: up to 20 km, up to 400 km, up to 800 km, and over 800 km. The critical values of the migration-related risk of psychosomatic disorders have been calculated for males and females. The most significant risk factor for the onset of psychosomatic disorders in young adults is the geographical distance between their current place of residence and their previous place of residence, with a range of 400 to 800 km.
CONCLUSION: The correlation between the geographical distance between an individual's initial and final place of residence and the risk of psychosomatic disorders in those in those experiencing significant emotional and mental loads has been described.



Polymorphism of genes involved in the regulation of blood pressure in elderly residents of the Arkhangelsk region
Abstract
BACKGROUND: Living in the northern climate is associated with increased cardiovascular stress, which highlights the necessity for the study of candidate genes associated with the risk of cardiovascular diseases in both the native population and newcomers. Polymorphic loci of the renin-angiotensin system, NO-synthase, and endothelin-1 system genes have been identified as contributors to cardiovascular dysfunction and age-related blood pressure shifts. It is therefore crucial to assess the genetic polymorphism in the elderly population.
AIM: To compare frequencies of gene alleles and genotypes involved in blood pressure regulation, including angiotensinogen AGT (rs699 and rs4762), angiotensin 2 type 1 receptor AGTR1 (rs5186), angiotensin converting enzyme ACE (rs4646994), endothelial NO synthase NOS3 and endothelin-1 EDN1 (rs5370) genes, in the native and non-native elderly population of the Arkhangelsk region.
MATERIALS AND METHODS: A cross-sectional study was conducted in a random sample of Arkhangelsk residents between the ages of 60 and 74 years (N=604, with 36.4% of males). The molecular genetic analysis was conducted to determine the alleles and genotypes of six genes that are involved in blood pressure regulation. The Stata 18.0 software was used to assess the deviations of empirical genotype distributions from the predicted Hardy–Weinberg equilibrium and to compare the empirical distributions between the study groups.
RESULTS: Alleles associated with the risk of cardiovascular diseases were minor in the study population. The genotype frequency distributions for the analyzed genetic variants were consistent with the Hardy–Weinberg principle, with the exception of the T704C variant of the AGT gene (rs699) in the native participants. The allele and genotype frequency distributions in the study sample were found to be similar to those reported worldwide and in European Russia. One exception was AGTR1 gene A1166C frequencies, with their 95% confidence intervals falling below the global level for both native and non-native elderly residents of the Arkhangelsk region. This may suggest that this allele is a selection variant associated with adaptation to the climate of the northern regions.
CONCLUSION: The genetic polymorphism in blood pressure regulation was found to be similar between the native and non-native populations of the Arkhangelsk region. However, the AGTR1 gene A1166C frequency among the native population and newcomers was found to be lower than that observed globally.
