Medical reasons for permanent and temporary disqualification of Turkish civil aviation pilots.

The aim of this study was to identify diseases that result in permanent and temporary medical disqualification for civil aviation pilots and their changes over the years. A retrospective analysis was conducted on the medical examination records performed in Turkey from 2018 to 2022, in accordance with ICAO and EASA standards. The permanent disqualification rate was 1.3%, and the temporary disqualification rate was 6.6%. The most common reasons for permanent disqualification among pilots were circulatory system diseases (24%), mental and behavioral disorders (22.9%), and nervous system diseases (11.5%). The most common reasons for temporary disqualification among pilots were circulatory system diseases (17.9%), digestive system diseases (11.8%), and health problems related to COVID-19 infection (9.5%). The data obtained from this study may be useful in developing preventive medicine approaches to prevent medical disqualifications and in-flight medical incapacitation.

Knowledge-guided generative artificial intelligence for automated taxonomy learning from drug labels.

To automatically construct a drug indication taxonomy from drug labels using generative Artificial Intelligence (AI) represented by the Large Language Model (LLM) GPT-4 and real-world evidence (RWE). We extracted indication terms from 46421 free-text drug labels using GPT-4, iteratively and recursively generated indication concepts and inferred indication concept-to-concept and concept-to-term subsumption relations by integrating GPT-4 with RWE, and created a drug indication taxonomy. Quantitative and qualitative evaluations involving domain experts were performed for cardiovascular (CVD), Endocrine, and Genitourinary system diseases. 2909 drug indication terms were extracted and assigned into 24 high-level indication categories (ie, initially generated concepts), each of which was expanded into a sub-taxonomy. For example, the CVD sub-taxonomy contains 242 concepts, spanning a depth of 11, with 170 being leaf nodes. It collectively covers a total of 234 indication terms associated with 189 distinct drugs. The accuracies of GPT-4 on determining the drug indication hierarchy exceeded 0.7 with "good to very good" inter-rater reliability. However, the accuracies of the concept-to-term subsumption relation checking varied greatly, with "fair to moderate" reliability. We successfully used generative AI and RWE to create a taxonomy, with drug indications adequately consistent with domain expert expectations. We show that LLMs are good at deriving their own concept hierarchies but still fall short in determining the subsumption relations between concepts and terms in unregulated language from free-text drug labels, which is the same hard task for human experts.

Prevalence of signs of professional burnout among medical workers involved in providing medical care for circulatory system diseases

BACKGROUND: Among 13 thousand doctors interviewed in 2021, 42% displayed signs of professional burnout. This phenomenon negatively affects the frequency of repeated hospitalizations, the number of adverse events, and increased employee turnover. However, studies concerning burnout in doctors are rare and do not focus on specialists who provide medical care for patients with circulatory system diseases (CSD). AIM: was to assess the level of burnout in medical workers involved in the provision of medical care for patients with CSD and to explore staff perceptions of its prevention. MATERIALS AND METHODS: A sociological survey (based on the standardized Maslach Burnout Inventory questionnaire) was conducted among medical personnel (women represented the majority of the sample — 76%, men — 24%). The sample is represented by doctors (n=89), nursing staff and auxillary nurses (NSAN) (n=128). The mean age for the whole group of respondents was 40.7±0.7, professional experience lasted 12.0±0.6 years. Standard methods of descriptive statistics were used for the data analysis. The age characteristics of the group had no significant differences by professional categories. Doctors had 39.0±1.2 years (min — 24, max — 63), NSAN had 41.0±0.6 years (min — 19, max — 67). Professional experience lasted differed doctors 39.0±1.2 years, in NSAN — 12.3±0.8. Men were characterized by a mean age of 36.7±1.6 years and professional experience lasted 10.0±1.2 years and women 42.0±0.7 years and 12.6±0.7 years, respectively. The character of distribution of quantitative data in the presented study was analyzed using the Kolmogorov–Smirnov and Shapiro–Wilk criterion. RESULTS: 80.2% of respondents presented with a high level of reduced professional accomplishments (RPA), 53.4% — a moderate average level of depersonalization. The emotional exhaustion was similar in all respondents, although average level of emotional exhaustion was the most prevalent (39.6%). 43.8% of doctors had an average level of emotional exhaustion, which is higher compared with NSAN — 37.5%. Clinical and paraclinical units are associated with a medium level of emotional exhaustion and a high RPA. At the same time, paraclinical units are characterized by a medium level of depersonalization, in contrast to clinical units, which are found to have a high level of this factor. According to the respondents, possible measures to prevent emotional burnout should include a set of measures including, rational distribution of responsibilities within departments, workload among the staff, as well as the formation of special skills to overcome stressful situations and optimization of activities with the help of digital solutions (support system for medical decisions, etc.). CONCLUSION: Working as medical staff and providing medical care for patients with CSD is strongly associated with a high level of reduced professional accomplishments (80.2% of respondents). Proper measures for the prevention of emotional burnout should primarily include organizational solutions focused on optimizing internal processes in medical staff’ work. According to the respondents, among the measures aimed at the prevention of emotional burnout, the most demanded may be: rational distribution of responsibilities within departments, workload among staff, as well as the formation of special skills to overcome stressful situations and optimization of activities with the help of digital solutions (medical decision support system, etc.).

Influence of medical-social and socio-economic factors on infant mortality rate in the Republic of Ingushetia

BACKGROUND: The infant mortality rate, as one of the indicators of the health and quality of life of the population, is an important factor that determines the country’s healthcare priorities. Despite the steadily decreasing infant mortality rates in the Russian Federation, the value of this indicator varies by region; thus, studying the factors influencing its value is relevant. If the leading medical, social, and socioeconomic factors that influence the level of infant mortality could be determined using data from a representative region (Republic of Ingushetia), the main directions for organizing measures aimed at reducing mortality among children in the first year of life will be identified. AIM: To determine the main medical, social and socio-economic factors that influence the infant mortality rate in the Republic of Ingushetia. MATERIALS AND METHODS: An observational single-center retrospective study was performed to examine the influence of medical, social, and socioeconomic factors on the mortality rate of children aged 1 year in the Republic of Ingushetia. The obtained data were compared with similar indicators for the Russian Federation as a whole and the North Caucasus Federal District. RESULTS: During the study period (2011–2019), significant changes were observed in infant mortality rates in the Republic of Ingushetia: infant mortality has decreased because of the age components, leading to the normal ratio of neonatal and post neonatal mortality. Rates of infant mortality from certain conditions arising in the perinatal period, congenital anomalies, and nervous system and circulatory system diseases have significantly decreased. The proportion of women admitted under the supervision of antenatal clinics in the early pregnancy (up to 12 weeks) has increased, the incidence of morbidity among pregnant women has decreased, and the proportion of normal births has been increasing. Although many medical organizations have employed a sufficient number of medical personnel, the coverage for biochemical screening has decreased, detection of malformations and biochemical abnormalities during prenatal diagnostics was low, medical personnel have low qualifications, and the shortage of obstetric and pediatric beds and pathology beds for newborns and premature infants was significant. A statistically significant dependence of the frequency of deaths of children aged 1 year on socioeconomic indicators−unemployment level, monetary income of the population, and housing conditions−was revealed. CONCLUSION: The main medical, social, and socioeconomic factors that influence infant mortality were analyzed using data from the Republic of Ingushetia. Positive and negative trends in the current state of the healthcare system of this republic have been identified.

Diosmetin as a promising natural therapeutic agent: In vivo, in vitro mechanisms, and clinical studies.

Diosmetin, a natural occurring flavonoid, is primarily found in citrus fruits, beans, and other plants. Diosmetin demonstrates a variety of pharmacological activities, including anticancer, antioxidant, anti-inflammatory, antibacterial, metabolic regulation, cardiovascular function improvement, estrogenic effects, and others. The process of literature search was done using PubMed, Web of Science and ClinicalTrials databases with search terms containing Diosmetin, content, anticancer, anti-inflammatory, antioxidant, pharmacological activity, pharmacokinetics, in vivo, and in vitro. The aim of this review is to summarize the in vivo, in vitro and clinical studies of Diosmetin over the last decade, focusing on studies related to its anticancer, anti-inflammatory, and antioxidant activities. It is found that DIO has significant therapeutic effects on skin and cardiovascular system diseases, and its research in pharmacokinetics and toxicology is summarized. It provides the latest information for researchers and points out the limitations of current research and areas that should be strengthened in future research, so as to facilitate the relevant scientific research and clinical application of DIO.

Small Intestinal Bacterial Overgrowth (SIBO) and Twelve Groups of Related Diseases-Current State of Knowledge.

The human gut microbiota creates a complex microbial ecosystem, characterized by its high population density, wide diversity, and complex interactions. Any imbalance of the intestinal microbiome, whether qualitative or quantitative, may have serious consequences for human health, including small intestinal bacterial overgrowth (SIBO). SIBO is defined as an increase in the number of bacteria (103-105 CFU/mL), an alteration in the bacterial composition, or both in the small intestine. The PubMed, Science Direct, Web of Science, EMBASE, and Medline databases were searched for studies on SIBO and related diseases. These diseases were divided into 12 groups: (1) gastrointestinal disorders; (2) autoimmune disease; (3) cardiovascular system disease; (4) metabolic disease; (5) endocrine disorders; (6) nephrological disorders; (7) dermatological diseases; (8) neurological diseases (9); developmental disorders; (10) mental disorders; (11) genetic diseases; and (12) gastrointestinal cancer. The purpose of this comprehensive review is to present the current state of knowledge on the relationships between SIBO and these 12 disease groups, taking into account risk factors and the causal context. This review fills the evidence gap on SIBO and presents a biological-medical approach to the problem, clearly showing the groups and diseases having a proven relationship with SIBO, as well as indicating groups within which research should continue to be expanded.

Palliative care at the present stage in Krasnoyarsk

Palliative medicine, aimed at ensuring the quality of life of patients with severe and incurable diseases, is becoming increasingly important in medical practice. In this article, we consider the current state and prospects for the development of palliative medicine in the city of Krasnoyarsk. The study showed that the number of patients in need of palliative care is increasing, mainly people older than working age with diseases of the cardiovascular system and oncological diseases. Approaches to anesthesia, prevention and treatment of pressure sores in hospice patients are described. The problems include a lack of qualified personnel and violations of the socio-psychological status of medical personnel, limited access to palliative medicine for remote areas of the region.

The implications of APOBEC3-mediated C-to-U RNA editing for human disease

Intra-organism biodiversity is thought to arise from epigenetic modification of constituent genes and post-translational modifications of translated proteins. Here, we show that post-transcriptional modifications, like RNA editing, may also contribute. RNA editing enzymes APOBEC3A and APOBEC3G catalyze the deamination of cytosine to uracil. RNAsee (RNA site editing evaluation) is a computational tool developed to predict the cytosines edited by these enzymes. We find that 4.5% of non-synonymous DNA single nucleotide polymorphisms that result in cytosine to uracil changes in RNA are probable sites for APOBEC3A/G RNA editing; the variant proteins created by such polymorphisms may also result from transient RNA editing. These polymorphisms are associated with over 20% of Medical Subject Headings across ten categories of disease, including nutritional and metabolic, neoplastic, cardiovascular, and nervous system diseases. Because RNA editing is transient and not organism-wide, future work is necessary to confirm the extent and effects of such editing in humans.

Years of Life Lost Due to Premature Mortality in Northern Iran: A Cross-sectional Study

Background: Years of life lost (YLL) is commonly used to determine the social and economic burden of loss due to premature mortality. The present study estimated YLL based on general mortality groups in Golestan Province, Iran, in 2018. Methods: In this cross-sectional study, by referring to the province death registration system information and using standard expected years of life lost (SEYLL) of the World Health Organization (WHO), YLL was calculated due to premature mortality based on general mortality groups in ICD-10 (international classification of diseases 10th revision). Results: The total number of deaths in Golestan Province was 8543 in 2018. The overall YLL due to premature mortality was 129838 years, of which 57.4% occurred among men. The major causes of YLL due to premature mortality (YLL%) were diseases of the circulatory system (I00-I99) (32.3%), external causes (V01-Y89) (17.3%), certain conditions originating in the perinatal period (P00-P96) (14.5%), and cancers (C00-D48) (13.9%). After diseases of the circulatory system, the most common cause of YLL due to premature mortality is external causes (22.9%) among men and cancers (16.2%) among women. In general, the highest YLL rate occurred due to circulatory system diseases (22.5 per 1000 people). Conclusion: According to the results of our study, most years of life lost in both sexes are related to diseases of the circulatory system, followed by external causes of morbidity and mortality. Therefore, it is important to pay attention to the diseases of the circulatory system and its causes, as well as external causes of morbidity and mortality.

Evaluation of reports received on a digital platform for monitoring and self-care of individuals facing the COVID-19 pandemic in Brazil: Contributions to public health

ObjectivesTo evaluate the contribution of the digital platform “Meu Diário de Quarentena (MDQ)" or My Quarantine Diary concerning the monitoring and self-care of individuals with COVID-19 in Brazil. And to analyze the epidemiological and clinical characteristics related to the disease and the users who adhered to the support provided by MDQ. MethodsMDQ was developed by a multidisciplinary team and offered to the general population to provide self-care and health education during the COVID-19 pandemic, relying on users' self-reporting of information (such as signs and symptoms, pre-existing health conditions, and medications used during quarantine). The outcomes were measured, and the web app's support experience for public health was reported. ResultsMDQ had 2439 active users on the platform, with 485 (19.9 %) self-reporting a COVID-19 diagnosis, mostly from individuals in the southeastern region of Brazil (56.5 %). The most common pre-existing health condition reported was related to circulatory system diseases. The most frequent reported signs and symptoms included headache, cough, myalgia, nasal congestion and muscle weakness. Corticosteroids, multivitamins, and anti-inflammatories were the most used medications during the pandemic period. There were several reports related to how users were feeling during the pandemic, and among these reports, negative feelings toward isolation stood out, such as “feeling lonely”, “anxious”, and “feeling useless”. A significant association was found between sex (p < 0.001) and age (p < 0.001) in relation to self-reported cases of COVID-19. ConclusionsThe use of MDQ during extended quarantine was an easy and interesting way of interaction and support for people during COVID-19 pandemic.

Comparative Efficacy of Monotherapy of Angiotensin-converting Enzyme Inhibitors Versus Angiotensin Receptor Blockers in Treating Essential Hypertension – A Meta-analysis

Background: Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are widely used medications for treating essential hypertension, but there is limited research comparing their effectiveness. To address this gap, a recent meta-analysis was conducted to evaluate and compare the efficacy of these two drug classes in decreasing blood pressure (BP) among patients with essential hypertension. Objective: Evaluating of comparative efficacy of ACEIs versus ARBs in reducing BP in essential hypertension. Methods: An extensive literature search for randomized controlled trials (RCTs) following PRISMA guidelines (2020), with inclusion criteria of age ≥18 years, with either gender and diagnosed of essential hypertension and receiving ACEIs or ARBs for at least 4 weeks. Patients with secondary hypertension, malignancy, symptomatic cardiovascular system (CVS) disease, hepatic involvement, and studies with Fimasartan and Allisartan were excluded. For this study, all RCTs that reported changes in mean systolic BP (SBP) and diastolic BP (DBP) before and after administration of the drugs were gathered. Standardized mean difference (SMD) was calculated using RevMan 5.4.1 software. The significance level was set at a P &lt; 0.05. Results: A total of 28 RCTs ( n = 9778) were included in our study. Both groups reduce SBP and DBP from the baseline values. Pooled analyses of studies showed that ARBs were superior to ACEIs with SMD = 0.179 in the random-effect model, 95% confidence interval (CI) (0.0975–0.260), P &lt; 0.001, and in the fixed-effect model, SMD = 0.207, 95% CI (0.167–0.248), P &lt; 0.001 in the mean reduction of SBP. Furthermore, for a mean reduction in DBP, ARBs were superior to ACEIs with SMD = 0.329 in the random-effect model, 95% CI (0.161–0.496), P &lt; 0.001, and in the fixed-effect model, SMD = 0.317, 95% CI (0.276–0.357), P &lt; 0.001. Our study included 28 RCTs with a combined sample size of 9778 participants. Both ACEIs and ARBs were found to effectively reduce SBP and DBP from their baseline values. However, our pooled analysis of the studies revealed that ARBs were more effective than ACEIs in reducing mean SBP, with an SMD of 0.179 in the random-effect model and 0.207 in the fixed-effect model. The 95% CIs for these estimates were (0.0975–0.260) and (0.167–0.248), respectively, with P &lt; 0.001. Similarly, for a mean reduction in DBP, ARBs were found to be superior to ACEIs with a SMD of 0.329 in the random-effect model and 0.317 in the fixed-effect model, with 95% CIs of (0.161–0.496) and (0.276–0.357), respectively, and a P &lt; 0.001. Conclusion: ARBs are more efficacious as compared to ACEIs in essential hypertension.

Occupational risk factors for the development of circulatory system diseases in bearing production workers

Prevention of circulatory system diseases (CSDs), preservation of the health of the working population is a priority task of the Russian Federation healthcare, in the solution of which it is of interest to study the causal relationships of the influence of production factors on the development of CSDs in workers of various professional groups. The purpose of this study was to assess the prevalence and occupational causality of diseases of the circulatory system in the main professional groups of bearing production workers. Material and methods. The occupational risk of developing CSDs in workers of the main professional groups in the bearing production was assessed based on the hygienic classification of production factors and chronic non-infectious morbidity according to medical examinations using the methodology for assessing occupational health risk. Results and discussion. It has been established that bearing production workers in the course of labor activity are exposed to the complex effects of harmful (class 3.1–3.4) factors of the working environment of various nature, which determine the a priori occupational health risk in categories from low to very high. The level of CSD prevalence was 446.4‰, while arterial hypertension was the most frequently established nosologic form (80.66 %). A high degree of causal relationships of arterial hypertension with the work was established for adjusters and machine operators (RR = 2.44; etiologic fraction (EF) 58.98 %; CI = 1.335–4.450), turners (RR = 2.32; EF = 56.93 %; CI = 1.184–4.451), grinders (RR = 2.31; EF = 56.63 %; CI = 1.189–4.469), hot-spot workers (RR = 2.16; EF = 53.64 %; CI = 1.193–3.901), which indicates professional conditioning. Conclusions. The complex impact of production factors contributes to the development of CSDs among workers in the production of bearings, which is confirmed by a high degree of causal relationship between arterial hypertension and work.

L-arginine, inosine and meldonium effect on the vascular wall reactivity of adult rats

Changes in the structure, metabolism and cardiovascular system function that develop during ageing are the basis for the circulatory pathology occurrence in old age. Currently, cardiovascular system diseases are one of the main causes of mortality in almost all developed countries. Therefore, searching for new drugs to correct the metabolism and functions of organs and systems whose activity is disrupted during ageing is an urgent problem. The article presents the study influence results of the synthesis precursor of endothelial relaxing factor - NO (ERF-NO) L-arginine, the purine nucleoside inosine and the β-oxidation inhibitor of fatty acids meldonium on the vascular wall reactivity of adult rats. When used separately, these drugs have been shown to cause slight relaxation of the thoracic aorta isolated segments in adult animals. When L-arginine, inosine and meldonium are used together, there is no summation of their pharmacological effect on blood vessels, however, some vasodilator effect potentiation is observed. The acetylcholine (Ach) vasodilator effect was significantly more than the vasodilator effect of the studied composition (L-arginine + inosine + meldonium), conventionally called Melarginine. It should be noted that, although the vasodilator Ach effect was significant, it was short-term, and the vasodilator effect of the studied combination (Melarginine) was long-lasting. A pronounced vasodilator response to Ach indicates the preservation of the endothelium in adult rats. Therefore, with intact endothelium in adult animals, Melarginine does not cause significant vascular relaxation. In aged rats, which typically exhibit endothelial damage, the effect of Melarginine may be more significant compared to adults. This will be the subject of our further study. Still, Melarginine has a small but long-lasting vasodilatory effect in adult rats, which also helps regulate vascular tone. _________________________________________________________________________________________ Keywords: vessel reactivity; endothelial dysfunction; L-arginine; inosine; meldonium; Melarginine

Peculiarities of adaptation of the cardiovascular system of combatants after exposure to combat stress and trauma

Abstract. Military operations are generally considered to be a pronounced psycho-traumatic situation due to specific factors that lead to persistent mental and somatic health disorders and a slowdown in the rate of further social adaptation of military personnel.&#x0D; Post-traumatic stress disorder (PTSD) is described as a set of complex somatic, cognitive, affective, and behavioral effects of psychological trauma.&#x0D; One of the essential features of combatants' PTSD is that after the end of the period of stay in the conditions of hostilities, a high incidence of chronic somatic diseases is manifested. There is a correlation in the neurotic symptoms (in all cases) of deterioration of the somatic condition, and exacerbation of somatic pathology aggravates mental disorders.&#x0D; The problem of morbidity and mortality from circulatory system diseases, blood poisoning and injuries is of particular relevance to combatants, as the onset of cardiovascular disease is closely related to the traumatic impact of wartime or PTSD. Particular attention to the medical and psychological consequences of the effects of extreme factors associated with combat on the body of military personnel is associated with both the prevalence of PTSD, which reaches 70-85%, and the duration of its symptoms.

Structure of circulatory system diseases and their genetic predictors in athletes with high intensity of training and competitive load

Introduction: Morphofunctional changes of the circulatory system organs detected in athletes may remain without due attention, as clinical (phenotypic) signs of pathological abnormalities are very similar to manifestations of cardiovascular system adaptation to intensive physical loads. The aim of the study is to propose a personalized algorithm for biomedical support of professional athletes with abnormalities and diseases of the circulatory organs based on clinical and genomic data.Materials and methods: The results of in-depth medical examination (2021-2023) of 15,464 athletes who are members of Russian sports teams were analyzed. The structure of circulatory system diseases according to the codes of the International Classification of Diseases, 10th revision (ICD-10), which were included in the summary report of the last examination, was analyzed. Fifty athletes with abnormalities and diseases of the circulatory system organs, experiencing different degrees of intensity of dynamic and static loads in accordance with the Mitchell classification, were selected from the study sample for full genome sequencing and subsequent clinical interpretation of the obtained data.Results: In the study sample the number of people with pathologic conditions of the circulatory system organs amounted to 6 946 people (45 %). Mitchell classification groups had statistically significant differences with respect to the prevalence of 10 diseases of the circulatory system organs. In 50 DNA samples of professional athletes, 5 probably pathogenic variants (10%), 19 variants with uncertain clinical significance (38%), relevant to the phenotype of a monogenic disease with circulatory system organ damage, were detected.Conclusion: Molecular genetic testing is an effective tool for differential diagnostics of pathologic and adaptive changes in the organs of the circulatory system. Carrying causative genes in combination with clinical signs allows to change the tactics of medical and biological support of an athlete according to the proposed algorithm.

Health policy developments in the Western Balkan Countries 2000-19: towards European Health and Health Care Policies.

Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have committed to becoming European Union (EU) member states. This, among others, implies that candidate/potential candidate states adopt legally authorized EU policies, including health. The study aims to identify the main country-specific health policy areas critical to the EU accession health policy dimension and present the change in associated selected health indicators from 2000 to 2019. The study draws on published reports and analyses of official statistics over time and cross-country. Health care policy adherence to the European Commission's recommended country-specific health actions was classified into five health policy areas: financing, payment, organization, regulation and persuasion. Key health policy areas for Western Balkan countries (WBCs) were identified. Health progress or lack thereof in catching up to the EU15 population health, health expenditure and the number of health professionals are measured. The European Commission prioritized financing and regulation for all WBCs in the five policy areas. Nine of the 18 analyzed selected health indicators showed divergence, and the other nine converged towards the EU15 averages. WBCs continue to face diverse public health challenges in improving life expectancy at birth, death rates caused by circulatory system diseases, malignant neoplasms, traffic accidents, psychoactive substance use, tuberculosis incidence, tobacco smoking prevalence and public-sector health expenditure. By 2019, there is limited evidence of WBCs catching up to the average EU15 health levels and health care policies. Closer attention towards EU health and health care policies would be favourable.

Anti-Inflammatory, Analgesic, Functional Improvement, and Chondroprotective Effects of Erigeron breviscapus (Vant.) Hand.-Mazz. Extract in Osteoarthritis: An In Vivo and In Vitro Study.

Osteoarthritis (OA) is a degenerative bone disease characterized by inflammation as a primary pathology and currently lacks therapeutic interventions to impede its progression. Erigeron breviscapus (Vant.) Hand.-Mazz. (EB) is an east Asian herbal medicine with a long history of use and a wide range of confirmed efficacy against cardiovascular and central nervous system diseases. The purpose of this study is to evaluate whether EB is worthy of further investigation as a treatment for OA based on anti-inflammatory activity. This study aims to assess the potential of EB as a treatment for OA, focusing on its anti-inflammatory properties. Analgesic effects, functional improvements, and inhibition of cartilage destruction induced by EB were evaluated in acetic acid-induced peripheral pain mice and monosodium iodoacetate-induced OA rat models. Additionally, the anti-inflammatory effect of EB was assessed in serum and cartilage tissue in vivo, as well as in lipopolysaccharide-induced RAW 264.7 cells. EB demonstrated a significant alleviation of pain, functional impairment, and cartilage degradation in OA along with a notable inhibition of pro-inflammatory cytokines, including interleukin-1β, interleukin-6, matrix metalloproteinases 13, and nitric oxide synthase 2, both in vitro and in vivo, in a dose-dependent manner compared to the active control. Accordingly, EB merits further exploration as a potential disease-modifying drug for OA, capable of mitigating the multifaceted pathology of osteoarthritis through its anti-inflammatory properties. Nonetheless, additional validation through a broader experimental design is essential to substantiate the findings of this study.

The Impacts of Heat and Air Pollution on Mortality in the United States

Abstract Extreme heat events stress the body and can result in fatalities, especially for those with underlying health problems. Air pollution is another threat to health and is an important confounder of extreme heat risks. However, previous empirical studies that have addressed the joint health impacts of air pollution and heat rarely considered the endogeneity and spillover effects of air pollution. To fill this research gap, this article investigates the interconnected impacts of extreme heat and fine particulate matter (PM2.5) on all-cause and cause-specific mortality. We correct the endogeneity of PM2.5 by applying the control function approach and explore transboundary externalities of all-source PM2.5 and wildfire-caused PM2.5. We use a county-year balanced panel dataset covering 2992 U.S. counties from 2001 through 2011. Results show that extreme heat and air pollution exacerbate each other and jointly increase mortality. Specifically, a 1-standard-deviation (SD) increase in the heat index results in 0.60% (95% confidence interval: 0.26%–0.97%), 2.14% (1.34%–2.94%), and 0.86% (0.41%–1.34%) more all-cause fatalities, fatalities from respiratory system diseases, and fatalities from circulatory system diseases, respectively. A 1-SD increase in PM2.5 results in 5.75% (3.61%–7.90%), 6.99% (3.01%–11.15%), and 2.93% (0.66%–5.28%) additional fatalities, respectively. Failure to consider the endogeneity of PM2.5 leads to a substantial underestimation of PM2.5 risk. In addition, our instrumental variable strategy offers evidence of spillover effects from PM2.5 and wildfires. Significance Statement This study illustrates how extreme heat events combined with air pollutants threaten health. This article investigates the interconnected impact of extreme heat and air pollution using data from 2992 United States counties over the 2001–11 period. Results indicate that extreme heat and air pollution jointly increase mortality. Results also show that wind-driven pollution from other counties and wildfires increase mortality.

SERPINE-1 gene polymorphism in patients with cardiovascular diseases

Currently, the issues of recurrent course of cardiovascular diseases are given great importance. Today, there is a search for more and more new factors and causes, including genetic ones, that contribute to the increase in the incidence of circulatory system diseases. The study of polymorphic variants of hemostasis system genes made it possible to study the molecular mechanisms underlying the causes of cardiovascular complications. Polymorphism of theSERPINE-1gene, encoding plasminogen activator inhibitor-1, is associated with the occurrence of cardiovascular diseases. This literature review examines the influence ofSERPINE-1gene polymorphism and the concentration of the plasminogen activator inhibitor-1 it encodes on the development and severity of circulatory system diseases; as well as the role of plasminogen activator inhibitor-1 as one of the indicators reflecting the antifibrinolytic potential of the blood. Taking into account the opinion of most authors, we can conclude that the polymorphism of theSERPINE-1gene and its homozygous variant 4G/4G, due to which the synthesis of plasminogen activator inhibitor-1 is increased, is an unfavorable predictor of many pathological processes. However, most of the data have been obtained on the association of theSERPINE-1gene polymorphism with cardiovascular diseases, where, according to most authors, the 4G/4G genotype is a prognostically negative variant. However, a number of researchers believe that the heterozygous 5G/4G variant is likely associated with the occurrence of cerebral ischemia. The inconsistency of the data obtained, ofcourse, requires further study of the characteristics of theSERPINE-1gene polymorphism in various pathological conditions, which is an important prerequisite for understanding the mechanisms of a number of diseases. To prepare the review, a literature search method in PubMed databases for the period 2013–2023 was used.

The role of intestinal microbiota in the development of dyslipidemia and cardiovascular disease risk

The aim of the study: to summarize the study results on the interaction between intestinal microbiota and the human body in terms of the risk for dyslipidemia and cardiovascular system diseases. Material and methods. A descriptive and comparative study was conducted based on the analysis of scientific literature focused on the role of intestinal microbiota in the occurrence of dyslipidemia and the development of cardiovascular diseases. The following research methods were used: search, comparative, analysis of scientific literature, generalization, synthesis. Results. Gut microbiota plays an important role in maintaining health, and its pathology contributes to the risk for cardiovascular diseases. In some cases, monitoring the intestinal microbiota and the preventive use of pre- and probiotics can reduce the risk for developing cardiovascular system diseases. Conclusions. It has been found that trimethylamine-N-oxide, a microbiota-dependent metabolite, is the first of many existing bacterial products with the proven role in the development of cardiovascular system diseases.
