Cardiovascular, rheumatic, kidney, and neurodegenerative diseases and mental disorders are a common cause of deterioration in the quality of life up to severe disability and death worldwide. Many pathological conditions, including this group of diseases, are based on increased cell death through apoptosis. It is known that this process is associated with signaling pathways controlled by a group of gaseous signaling molecules called gasotransmitters. They are unique messengers that can control the process of apoptosis at different stages of its implementation. However, their role in the regulation of apoptotic signaling in these pathological conditions is often controversial and not completely clear. This review analyzes the role of nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H₂S), and sulfur dioxide (SO₂) in apoptotic cell death in cardiovascular, rheumatic, kidney, and neurodegenerative diseases. The signaling processes involved in apoptosis in schizophrenia, bipolar, depressive, and anxiety disorders are also considered. The role of gasotransmitters in apoptosis in these diseases is largely determined by cell specificity and concentration. NO has the greatest dualism; scales are more prone to apoptosis. At the same time, CO, H₂S, and SO₂ are more involved in cytoprotective processes.

Microplastics (MPs) and nanoplastics (NPs), formed as a result of plastic product degradation, pose a global environmental threat by penetrating biological systems and inducing systemic pathological changes. This systematic review, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines, aims to analyze the molecular and cellular mechanisms of the toxic effects of MPs and NPs on the human cardiovascular, nervous, reproductive, urinary, and digestive systems. The primary mechanisms include oxidative stress, inflammation, mitochondrial dysfunction, apoptosis, autophagy, ferroptosis, and impaired barrier functions. In the cardiovascular system, MPs and NPs contribute to endothelial dysfunction, disorders of lipid metabolism, and fibrosis; in the nervous system, they promote neuroinflammation, pathological protein aggregation, and psychiatric disorders; in the reproductive system, they lead to hormonal imbalance and reduced fertility; in the kidneys, they cause inflammation, and fibrosis and lead to deterioration of kidney function; and in the gastrointestinal tract, they contribute to dysbiosis and metabolic disorders. The literature search was conducted in the PubMed, Web of Science, and Scopus databases without limitations on date, language, or access. Studies were selected based on criteria of transparency, statistical validity, sample representativeness, and correctness of data interpretation. The review emphasizes the necessity of an interdisciplinary approach to developing prevention and treatment strategies, including reduction in exposure, antioxidant and immunomodulatory therapy, and restoration of barrier functions and microbiota. The data obtained reveal research gaps and identify directions for further study.

Артериальная гипертензия у беременных: дискуссионные вопросы национальных и международных рекомендаций

Public health strategies for the detection, prevention and treatment of cardiovascular diseases (CVDs) can be implemented at many levels as follows: from individual behavioral alterations to population-based strategies that affect different national and cultural communities. Despite the fact that the priority of primary prevention is treating hypertension and hyperlipidemia, great importance is given to improving behavioral and biological risk factors. Dietary modification, exercise and smoking cessation are specific interventions that can be targeted to reduce CVD risk at both the individual and population levels. Following a healthy lifestyle can potentially change factors such as overweight/obesity, hyperlipidemia, type 2 diabetes, and hypertension. The aim of this review was to present and summarize new data on the primary cardiovascular prevention with a focus on improving behavioral risk factors considered in the current guidelines.

Сердечно-сосудистые заболевания остаются основной причиной смерти и заболеваемости среди женщин. Гипертензивные нарушения во время беременности являются междисциплинарной проблемой, которая изучается на протяжении многих лет, но, к сожалению, остается нерешенной. Последствия, вызванные преэклампсией и другими формами артериальной гипертензии у беременных, достаточно серьезны как для матери, так и для плода. Предметом дискуссий остается вопрос, имеется ли прямая ассоциация гипертензивных нарушений беременности и преэклампсии с последующим развитием сердечно-сосудистых заболеваний или эти состояния имеют общие патофизиологические механизмы и факторы риска. Накапливаемые данные позволят персонально выделить группы высокого риска по развитию гипертензивных нарушений беременности и преэклампсии, что сможет улучшить профилактические и терапевтические подходы и разработать рекомендации по коррекции образа жизни на этапе подготовки к беременности.

Aim. To compare the cardio-ankle vascular index (CAVI) and the novel START vascular stiffness index and assess their values and correlations with clinical parameters.Material and methods. This multicenter study included 928 (403 men and 525 women) randomly selected patients, aged 18 to 89 years (mean age, 41±15,8 years). Inclusion criteria were age over 18 years. There were following exclusion criteria: mental disorder, severe somatic diseases and cancer, contraindications for volume sphygmography using the Fukuda Denshi VS-1500 VaSera system, no patient consent, ankle-brachial index 1,3. Further, according to the main parameters obtained using volum sphygmography, a novel START index was calculated. Comparison of index values and analysis of their correlation with clinical indicators, such as age, systolic blood pressure, diastolic blood pressure, pulse pressure (PP), body mass index and heart rate (HR), were carried out using simple and multiple linear regression, dispersion analysis, calculation of the Pearson coefficient (r), in the software environment R version 4.0.2.Results. Statistical analysis revealed a high correlation between START and CAVI indices (r=0,986, p0,05). According to multiple linear regression, the relationship between diastolic blood pressure at the age of 30-60 years and PP at the age of 18-40 years with the START index is more pronounced than with the CAVI index. However, further study of the mathematical model did not reveal a significant difference in the index values for groups with and without high blood pressure.Conclusion. The START vascular stiffness index significantly correlates with the CAVI index, showing no significant differences from CAVI in quantitative relationships with blood pressure, body mass index, heart rate, and sex in various subgroups of the subjects.
