Incretins today: multiple effects and therapeutic potential
Glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) are the incretin hormones initially discovered in the 1960s. GIP and GLP-1 have gained great scientific interest due to their properties in increasing insulin secretion and lowering blood glucose levels. The study of these incretin hormones has progressed substantially in recent decades, in that their systemic effects has begun to be actively discussed. In particular, incretins are involved in the pathogenesis of obesity and non-alcoholic fatty liver disease. Moreover, incretins are able to improve cognitive function, suppress the formation of β-amyloid plaques and provide an oncoprotective effect. Recent data show promising oncoprotective effect of GLP-1 agonists on prostate and breast cancer. This review provides systematisation of recent data on the role and mechanisms of action of incretin hormones on carbohydrate metabolism, as well as effects not related to glucose homeostasis, which contributes to a better understanding of potential vectors for the development of incretinotropic therapy. In addition, this review offers insight into pathogenic prerequisites and highlights the current issues in creating innovative polyagonists for treatment of type 2 diabetes mellitus
Forecast of Stability of the Economy of the Russian Federation with the AI-System “Decision Tree” in a Cognitive Model
Increased use of modern mathematical
algorithms based on artificial intelligence determined the relevance of this
study, which is important for predicting the sustainable development of the
country's economy in general and its banking sector in particular. To achieve
the purpose of the research, the presented work used methods such as
monographic, analytical, statistical, cognitive model, and artificial
intelligence system "Random Forest". The aim of the study is to prove
or disprove the hypothesis that, using a cognitive model, using the Random
Forest ML model, it is possible to obtain an accurate forecast of the value of
the "sustainability coefficient", reflecting the stability of the
domestic economy. The scientific novelty of the study is due to the fact that
the author's approach is proposed for indicating the crisis state of the
economy through the calculation and neural network forecasting by the machine
learning model "Random Forest" of the "Stability
Coefficient" of the economy, which is calculated as the quotient of dividing
the profit index of the banking system to the GDP growth index. The possibility
of practical application in the banking sector determines the practical
significance of the conducted scientific research since the approach proposed
by the authors regarding the formation of a forecast of the “sustainability
coefficient” can be successfully used to support managerial decision-making at
the strategic level in the banking system. A hypothesis was put forward and
proven that based on the use of a digital cognitive model and the Random Forest
ML system, a forecast of economic stability can be successfully generated
Long-term uroseptic and metabolic effects of a herbal medicinal preparation in women with type 2 diabetes taken gliflosins
Background. The problem of urinary tract infections, including recurrent cystitis, and the choice of effective and safe means of treatment and prevention, taking into account the increasing burden of antibiotic resistance, are extremely relevant.
Aim. To evaluate the effectiveness and safety of the herbal medicine Canephron® N for the prevention of exacerbations of recurrent cystitis and its effect on metabolic parameters in patients with type 2 diabetes mellitus taking sodium glucose cotransporter type 2 inhibitors.
Material and methods. A prospective, randomized, open-label, parallel group study of 60 women without exacerbation of recurrent cystitis. The main group took the drug Canephron® N for 3 months, 2 tablets 3 times a day, and for the next 3 months they were monitored without taking the drug. The main evaluation parameters were: frequency of cystitis relapses, albumin/creatinine ratio in the morning urine, glomerular filtration rate, plasma lipid profile, glycemia and malondialdehyde in low-density lipoproteins.
Results. 3 months after the end of taking the drug Canephron® N, patients in the main group maintained a positive effect in reducing exacerbations of cystitis – 3.3 times less relapses of the disease (3 and 10%, respectively; p=0.038). The urine albumin/creatinine ratio, lipid profile, glycemia and malondialdehyde in low-density lipoproteins after a 3-month treatment period had positive dynamics, but in the long-term period they corresponded to the values at the inclusion stage, both in the main and control groups.
Conclusion. Prophylactic use of the herbal drug Canephron® N for 3 months is safe and reduces the frequency of relapses of cystitis in women with chronic cystitis against the background of diabetes mellitus taking sodium glucose cotransporter type 2 inhibitors, this effect persists for 3 months after discontinuation of the drug. Positive metabolic effects are associated with taking Canephron® N and are gradually leveled out when it is discontinued
Potential new application points of SGLT2 inhibitors in patients with heart failure in combination with diabetes mellitus, non-alcoholic fatty liver disease and anemia (literature review)
Chronic heart failure is a global cardiac problem. The last decade can rightly be called a breakthrough in the treatment of this nosology, due to the emergence of a new group of drugs - SGLT2 inhibitors (gliflozins), which, both in patients with initial heart failure with different ejection fraction, and in the presence of risk factors for its development, have a persistent positive impact on the number of hospitalizations for heart failure. A number of pleiotropic effects of SGLT2 inhibitors are also attractive to the clinician, which include moderate weight loss, a decrease in body fat in visceral fat depots, a decrease in the level of hepatic transaminases in the blood, stimulation of erythropoiesis, which organically complements the strategy of complex cardiorenometabolic protection and emphasizes the unique role of this class drugs in modern cardiology. In the near future, we will have to learn the results of the ongoing multiple studies of gliflozin, which is highly likely to open new historical horizons in the treatment of patients with cardiovascular diseases, including various categories of patients with acute and chronic heart failure
Trade-economic cooperation of Ukraine and China within COVID-19 Pandemic and in post-pandemic time
Modern trends of trade-economic relations of the countries within the COVID-19 pandemic have been systemized in the development of mutual relations in particular economy sectors have been identified. Direct connection between the increase of export volume to China and Ukraine GDP growth has been established in the study based on the correlation-regression analysis. Weaknesses and strengths as well as opportunities and threats of mutual relations within the pandemic have been defined. The influence of the world crisis, creating a free trade area, and other factors on foreign trade circulation between Ukraine and China have been studied with the tools of empirical gravity model of international trade. Foreign trade circulation up until 2022 with and without creating a Free Trade Area has been forecast based on the modelled data. Perspective directions of trade-economic relations have been defined; the strategy of extending the trade-economic integration of Ukraine and China within the COVID-19 pandemic and in post-pandemic time within customs tariffs liberalization, intensification of symmetric interdependence and complementarity between the countries, within creating a free trade area, diversifying trade turnovers, overcoming the pandemic, reduction of crisis consequences, and strengthening cooperation in new industries of post-pandemic time has been grounded
Associations of sex hormones with components of insulin-glucose homeostasis
In this literature review, an attempt is made to analyze the interrelationships of the main sex hormones with the processes of development and progression of insulin resistance as a fundamental pathogenetic component of insulin-glucose homeostasis. In the evaluation of sex steroids, a complex approach was used - the associations of both androgens and estrogens in males and females are described in detail, a great deal of attention is paid to the violation of the secretion and effectiveness of the main adipocytokines - leptin and adiponectin in the sex hormone-insulin-glucose interaction chain. At the end of the review, new data on the expression of sodium-dependent glucose cotransporter (SGLT) and glucose transporters (GLUT) in animals, depending on sex, are presented
Physicians’ knowledge and preferences in tactics of management and rational pharmacotherapy of arterial hypertension in pregnant women (PHYGEST study)
Introduction: The issues of rational antihypertensive therapy in pregnant women are always extremely relevant, since high blood pressure in a pregnant woman is associated with serious risks for a mother and a fetus. The aim of the study: To determine the knowledge and preferences of physicians in the management of pregnant women with arterial hypertension. Materials and methods: A multicenter study was conducted in 2018–2021 using an anonymous questionnaire among 411 doctors from 8 regions of Russia. Results and discussion: The levels of knowledge and preferences of specialists in the issues of diagnosing and formulating a diagnosis of arterial hypertension and preeclampsia in pregnant women, prescribing basic and additional drugs for the treatment and prevention of hypertension were revealed, and the degree of compliance with the current clinical guidelines was assessed. Conclusion: Due to the insufficient level of knowledge of specialists, it is required to pay increased and special attention to this problem, strengthen control over compliance with clinical guidelines, and introduce it into postgraduate recommendations and continuing education programs
Rational antimicrobial chemotherapy: assessment of the level of basic knowledge of general practitioners. Final results of the KANT project
Introduction: The irrational use of medicines leads to a decrease in the quality of care, an increase in treatment costs and side effects. In the case of antibacterial drugs, in addition to all the above-mentioned consequences, their improper use can lead to an aggravation of the existing and quite challenging problem of our time – the growth of antibiotic resistance among pathogenic microorganisms. The aim of the study: to determine the level of basic knowledge of medical specialists in the field of a rational use of antimicrobial drugs (AMD). Materials and methods: The study was based on an analysis of an anonymous multicenter survey in the framework of the KANT project (the full name of the project is “Physicians’ (Students’) Knowledge of Antimicrobials Usage”). It was conducted in 2018–2019 in 10 major centers of Russia. Results and iscussion: According to the results of the study, the respondents showed a low level of knowledge of the rational use of antibacterial drugs. The best results are obtained for questions No.1 (time interval for evaluating the effectiveness of the initial antimicrobial therapy (AMT)), No.2 (rationality and period of AMD change with a positive clinical effect), and No.9 (determining the mode of using the proposed drugs), whereas the worst results were obtained for questions No.3 (determining irrational combinations of AMD), No.4 (determining a situation requiring a long course of AMT), and No.7 (choosing auxiliary drugs for bacterial respiratory infections). Conclusion: The results obtained in the study indicate the need for additional educational activities among health professionals
Preliminary paleoenvironmental analysis of permafrost deposits at Batagaika megaslump, Yana Uplands, northeast Siberia
A megaslump at Batagaika, in northern Yakutia, exposes a remarkable stratigraphic sequence of permafrost deposits ~50–80 m thick. To determine their potential for answering key questions about Quaternary environmental and climatic change in northeast Siberia, we carried out a reconnaissance study of their cryostratigraphy and paleoecology, supported by four rangefinder 14C ages. The sequence includes two ice complexes separated by a unit of fine sand containing narrow syngenetic ice wedges and multiple paleosols. Overall, the sequence developed as permafrost grew syngenetically through an eolian sand sheet aggrading on a hillslope. Wood remains occur in two forest beds, each associated with a reddened weathering horizon. The lower bed contains high amounts of Larix pollen (>20%), plus small amounts of Picea and Pinus pumila, and is attributed to interglacial conditions. Pollen from the overlying sequence is dominated by herbaceous taxa (~70%–80%) attributed to an open tundra landscape during interstadial climatic conditions. Of three hypothetical age schemes considered, we tentatively attribute much of the Batagaika sequence to Marine Oxygen Isotope Stage (MIS) 3. The upper and lower forest beds may represent a mid–MIS 3 optimum and MIS 5, respectively, although we cannot discount alternative attributions to MIS 5 and 7
