Published: March 2022

Background: Emerging evidence suggests that gut dysbiosis contributes to Parkinson’s disease (PD) by signaling through microbial metabolites. Hippuric acid (HA), indole derivatives, and secondary bile acids are among the most common gut metabolites. Objective: To examine the relationship of systemic concentrations of these microbial metabolites associated with changes of gut microbiota, PD status, and severity of PD. Methods: We enrolled 56 patients with PD and 43 age- and sex-matched healthy participants. Motor and cognitive severity were assessed with Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) part III motor score and the Mini-Mental State Examination (MMSE), respectively. Plasma concentrations of targeted gut metabolites were measured with liquid chromatography-tandem mass spectrometry. Gut microbiota was analyzed with shotgun metagenomic sequencing. Results: Compared with controls, PD patients had significantly higher plasma levels of HA, indole-3-propionic acid (IPA), deoxycholic acid (DCA), and glycodeoxycholic acid (GDCA). After adjustment for age and sex in a multivariate logistic regression analysis, plasma levels of HA (odds ratio [OR] 3.21, p < 0.001), IPA (OR 2.59, p = 0.031), and GDCA (OR 2.82, p = 0.036) were associated with positive PD status. Concentrations of these gut metabolites did not correlate with MDS-UPDRS part III score or MMSE after adjustment for confounders. Microbial metabolite levels were associated with the relative abundance of pro-inflammatory gut bacteria. Conclusion: Aberrant gut microbial metabolites of HA, indole derivatives and secondary bile acids associated with specific gut microbiota changes were observed in patients with PD.

Published: March 2022

BACKGROUND: Inadequate nutrient intakes in adolescents may negatively affect their future health. The identification of inadequate micronutrient intakes by dietary study provides essential information to guide educational strategies for promoting healthy eating habits. OBJECTIVE: To assess the daily micronutrient intake and the prevalence of inadequacy in a sample of middle and high-school pupils in the Rif region of Morocco. METHODS: A cross-sectional study collected dietary information from food records over three non-consecutive days in a sample (n = 302) of Moroccan Riffian adolescents (12–18 years). The DIAL software, adapted for commonly eaten Moroccan foods, was used to estimate micronutrient intakes. The proportion of individuals with intakes below the Estimated Average Requirement (EAR) or the Adequate Intake (AI) level and the probability approach were used to estimate the prevalence of inadequacy. RESULTS: Regardless of gender and age group, our subjects were found to be particularly at risk of inadequate intakes of vitamins E and D, calcium and potassium. Older adolescents (14–18 years) also showed a risk of inadequate intake of folate, biotin, magnesium, iodine and zinc (among boys). CONCLUSION: For many nutrients, the daily diets of our Riffian adolescents do not meet the recommended intake levels. We emphasize the need for monitoring the dietary habits of adolescents and the development of nutrition education programs. Further studies which include the clinical and biological assessment of nutritional status, as well as the regular collection of quality and nationally representative micronutrient data, are recommended.
Vitamin D in SARS-CoV-2 infection
Authors: Decyk Agnieszka
Published: March 2022

Background. SARS-CoV-2 virus is one of the largest RNA viruses, included in the coronavirus group, showing tropism to airway epithelial cells. SARS-CoV-2 causes an acute respiratory infectious disease, Covid-19. According to WHO reports, mortality due to Covid-19 is higher in the elderly and in those burdened with comorbidities such as diabetes, obstructive pulmonary disease, coronary artery disease, cancer, hypertension, hepatitis B, obesity or chronic kidney disease.
Objective. The aim of the study was to review the current literature on the influence and importance of vitamin D levels on the course of SARS-CoV-2 infection.
Material and method. A systematic review of studies published from January 1, 2009 to June 31, 2021 has been performed. For this purpose, bibliographic databases such as PubMed and Scopus were searched. The following keywords and combinations were used: Covid-19, vitamin D, 25-hydroxy-vitamin D, vitamin D supplementation, SARS-CoV-2.
Results. It has been shown that vitamin D plays an important role in the mechanisms of the innate immunity in the course of the acute respiratory infections. The overlapping factors of the severity of COVID-19 disease, vitamin D deficiency, and the prevalence of obesity, age scare, ethnicity, has led some researchers to hypothesize that vitamin D supplementation may be promising as a preventive or therapeutic measure for COVID-19.
Conclusions. A very important factor that has an immunomodulatory character is vitamin D, the adequate supplementation of which can be a preventive or therapeutic measure in case of SARS-CoV-2 infection, especially in elderly people, with obesity and other chronic diseases.
Effects of dietary components on intestinal short-chain fatty acids (SCFAs) synthesis in healthy adult persons following a ketogenic diet
Authors: Gudan Anna
Published: March 2022

Background. The ketogenic diet (KD) has been used for almost 100 years in the treatment of drug-resistant epilepsy in children - and adults. The intestinal microbiome has a climax character, and the main factor changing its composition and functions is the diet. Both increased biodiversity and the production of short-chain fatty acids (SCFAs) are important indicators of gut barrier function. SCFAs are synthesized by microorganisms through the fermentation of dietary fibre provided with the diet. They are an important element in signal transduction from the digestive system to other tissues. To date, there is little research to determine how the use of KD alters the SCFAs profile of the human stool.
Objective. To assess the SCFAs profile in the stool of healthy and active KD users.
Material and methods. Study group: amateur athletes following KD. Control group: amateur athletes following a regular diet (carbohydrates min. 50%); gender: men and women aged 18-60. Material: stool sample (1x10 g). SCFAs content was determined in stool samples using gas chromtography method. Participants completed a Food Frequency Questionnaire (FFQ) and a 72-hour food diary.
Results. There research has shown differences in the amount of SCFAs, as far as the results obtained from the two groups are concerned. The discrepancies referred to the levels of acetic, butyric, iso-butyric, valeric, and isovaleric acids. Spearman's rank correlation analysis showed a strong relationship between the consumption of selected dietary components (vegetables, fruits, red meat, poultry, fish, nuts and seeds, sugar, sugar substitutes, fats) and the SCFAs content in the stool of the study group.
Conclusions. High consumption of cruciferous and leaf vegetables, berries and nuts on a ketogenic diet may have a positive effect on the profile of short-chain fatty acids produced by the gut microbiome. Changing the diet towards a greater supply of plant products may prevent proteolytic fermentation and reduce the negative effects of microbiome changes caused by an oversupply of protein and fat in the ketogenic diet.

True cost of food and land degradation
Authors: Mirzabaev Alisher , von Braun Joachim
Published: March 2022

Achievement of Sustainable Development Goals critically depends on well-functioning food systems which can provide sufficient and healthy food for all in an environmentally sustainable, economically viable and socially equitable manner. However, current food systems are failing on all of these dimensions. In fact, food systems are generating substantial amounts of environmental, health-related, social, and economic externalities negatively affecting the well-being of present and future generations of people, particularly that of the poorest and most vulnerable. True cost accounting approaches, a research frontier in sustainability sciences, seek to comprehensively measure these so far unaccounted externalities from food systems to propose solutions for addressing their negative social welfare effects. Contributing to discussions on true costs of food, this paper traces the environmental costs of ecosystems degradation due to cropland expansion during the period of 2001 to 2009 at the global level. The results show that cropland expansion caused by growing food demands has led to the degradation of 511 million hectares of higher value forest, woodland, shrubland and grassland ecosystems globally, with the total economic costs equaling 435 billion U.S. dollars. This means that each year the global community is incurring 54 billion U.S. dollars of externality costs from food systems because of cropland expansion alone. Addressing this problem requires a flexible government regulation combining incentive mechanisms such as payments for ecosystem services and carbon pricing, with legislative deterrents, e. g., environmentally friendly cadastral planning, fines, and taxes. Current research on true cost accounting is primarily focused on identifying the extent of externalities from food systems. However, knowledge does not always automatically translate into action. The key impetus for future actions for true pricing of food would come from closing knowledge gaps on transaction costs for the implementation of true pricing and the development of innovative solutions for reducing them.

The authors developed an environment-friendly demolition mechanical system for a large reinforced concrete structure for an actual site. The steam pressure cracking agent (SPC, non-explosive) is a method that can safely and quickly separate concrete because it produces lesser vibration and sound than the blasting method, which uses explosives. The authors showed that the direction of cracking can be controlled by an induction hole. The principle of control is that the elastic wave of the compression stress generated from the SPC reaction changes to a tensile elastic wave at the induction hole, which initiates a crack. Furthermore, in the SPC method, a large amount of concrete powder generated by the explosion method was not produced, and there was no risk of secondary contamination by fine concrete powder. The area over which the crack propagated depends on the energy generated from the SPC. The relationship between the two is linear. For reinforced concrete, the energy of the SPC is used for both the destructive energy of the concrete and the energy of the cutting of the reinforcing steel bar, which quickly breaks with low energy. By applying an SPC to dismantle large reinforced concrete structures, controlled cracking can be achieved safely and quickly without any environmental pollution. A fracturing method using a SPC is an effective method for the decommissioning of nuclear power plants and the dismantling of concrete structures. In this report, we report a remote drilling system that can be used to remotely install loading holes and guiding holes for the SPC and perform effective controlled fracturing.

Published: March 2022

É sabido que na escola encontra-se muitos casos de dificuldades de aprendizagem e, o que tem se percebido, é que os problemas familiares podem incidir sobre a aprendizagem escolar. Logo, vê-se a necessidade de capacitação dos profissionais da escola para identificar dificuldades de aprendizagem oriundas da família e estimular buscas de soluções. Diante desta constante, leva-se ao levantamento a seguinte questão: Qual a relação entre as situações familiares e a dificuldade de aprendizagem escolar dos alunos? O estudo teve como objetivo geral compreender a relação entre o contexto familiar e as dificuldades de aprendizagem dos alunos, partindo do pressuposto que o desempenho escolar depende de diversos fatores, dentre estes, a família. O presente artigo caracterizou-se segundo os objetivos como descritiva e com relação aos procedimentos de coletas, este estudo é do tipo bibliográfico e qualitativo através de fontes secundárias pela identificação e análise dos dados escritos em livros e artigos de sites e de revistas. Através das pesquisas realizadas, pode-se perceber que existe um enorme reflexo sobre a aquisição da aprendizagem quando os alunos vivenciam situações conflituosas no seu berço familiar. Estudos revelaram, também, que crianças que apresentam problemas familiares podem ter um rendimento inadequado e ainda não apresentarem o retorno esperado no processo educacional ao qual estão sendo submetidas. Assim, ficou evidente a necessidade da interação da família com a escola para que esses fatores externos possam ter um efeito menos nocivo na realidade escolar desses alunos.

Published: March 2022

Background: NCCN guidelines recommend surgical excision for patients with atypical ductal hyperplasia (ADH) on percutaneous biopsy. Improved imaging and biopsy techniques have lower contemporary upgrade rates, challenging standard practice. We sought to identify low-risk features of ADH to define patients who may benefit from active monitoring over surgical excision.Methods: A retrospective analysis identified 87 stereotactic biopsies diagnosing ADH undergoing surgical excision at a single institution from 01/2008 to 10/2015. Imaging was reviewed for lesion size and residual calcifications. Biopsy slides were reviewed for ADH features. Categorical variables were analyzed using Chi-square and Fisher’s exact tests; continuous variables with T- and Wilcoxon tests. Logistic regression model was used to determine the association between the number of low-risk features present and odds of upgrade.Results: Upgrade was identified in 13 cases (14.9%; 11 ductal carcinoma in situ and 2 invasive breast cancer). Low-risk imaging features included imaging size <1cm (P=0.004) and >50% removed by biopsy (P=0.03). The only significant low-risk pathologic feature was the lack of micropapillary features (P=0.10). Focal ADH (1-2 foci, P=0.12) was felt to be clinically significant. Those with the lowest risk of upgrade (0%) had all 4 low-risk features (n=17, 20%). When comparing biopsies that differed by one low-risk feature, the biopsy with one less low-risk feature present had 129% increase in odds of upgrade (exact OR=2.29, 95% CI 1.35, 4.15, P=0.001). Conclusion: Overall upgrade rate was low in this contemporary cohort. Patients at lowest risk for upgrade had all 4 low-risk features and could be safely offered active monitoring over surgical excision.

Published: March 2022

Introduction. The syndrome of undifferentiated connective tissue dysplasia (UCTD) combines a group of diseases that is heterogeneous in origin and polymorphic in clinical manifestations. UCTD is characterized by joint hypermobility and pain in the joints and back. In the last decade, osteopathic methods for the diagnosis and correction of dorsalgia and joint mobility disorders, including UCTD, have become widespread. However, the results of osteopathic correction in children and adolescents with undifferentiated dysplasia have not yet been fully investigated.The aim of the study was to research the results of osteopathic correction in children and adolescents with the syndrome of undifferentiated connective tissue dysplasia.Materials and methods. The study involved 48 children and adolescents aged 10 to 18 years. A study group and a control group were formed by the simple randomization method. Each group consisted of 24 participants: 5 boys and 19 girls in the main group; 7 boys and 17 girls in the control. The participants of the main group received osteopathic correction. The participants in the control group received drug therapy and lifestyle correction. In both groups, osteopathic status, intensity of pain syndrome, functioning of the autonomic nervous system (the predominance of sympathetic or parasympathetic influences on the cardiovascular system), the level of depression and anxiety were assessed before and after the treatment.Results. Osteopathic correction in children and adolescents with UCTD was accompanied by a statistically significant (p<0,05) decrease in the detection frequency of regional somatic dysfunctions of the head, neck, thoracic region, and pelvis. There was also a statistically significant (p<0,05) decrease in the intensity of pain syndrome, normalization of the functioning of the autonomic nervous system, which manifested in the achievement of a state of autonomic balance, assessed by the Kerdo index, a decrease in the level of depression and anxiety. Standard treatment, including drug therapy and lifestyle correction, was accompanied by the normalization of the functioning of the autonomic nervous system and a decrease in the level of depression. However, osteopathic correction led to statistically significantly more pronounced results for these indicators compared to the results of standard treatment.Conclusion. The obtained results make it possible to consider the possibility of including osteopathic correction in the complex treatment of children and adolescents suffering from undifferentiated connective tissue dysplasia, since it have a positive effect on the course of the main disease. It is advisable to conduct a study on a larger sample of patients with subsequent follow-up assessment.

It is determined that the economic mechanism of economic management of the nature is a set of methods, means, instruments and forms of budget-tax and financial-credit regulation of economic development and use in the reproduction process of the natural component of national wealth, as well as the implementation of activities aimed at the reproduction of natural resource potential and environmental protection. It is substantiated that in the current socioeconomic and political-legal conditions, the economic mechanism of economic management of the nature operates with an overly narrowed specification of methods and instruments, which makes it impossible to fully ensure a sufficient level of financing for the implementation of environmental projects and priorities for expanded reproduction and enhance of the natural resource potential. It is proved that in the unfavorable conditions of the European natural gas market for the national economy and crisis phenomena caused by the curtailment of business activity due to the spread of the coronavirus pandemic, budgetary opportunities for financing environmental expenditures are limited. Researches have shown that in the dynamics of the real value of environmental expenditures of both the State and local budgets in 2002-2020 in general, there is a downward trend, which indicates a real decrease in the volume of public financing of environmental protection. It is substantiated that due to the deregulation of land relations, that is, the transfer of the State-owned agricultural land outside settlements to communal ownership, additional resource opportunities have been formed to increase the efficiency of the use of instruments of the economic mechanism of economic management of the nature at the local level. It is determined that in the conditions of an overly unified system of budget and tax regulation of economic management of the nature and limited opportunities for financing environmental activities, ensuring a high level of efficiency of functioning of the economic mechanism of economic management of the nature at the local level requires the installation of a complex of incentives into the range of its instruments and methods. Such incentives will orient the entities of agrarian entrepreneurship to the introduction of additional capacities of organic farming, organic cattle breeding and organic feed production. It is substantiated that such incentives are represented by tax and budget preferences.

The purpose of the article is to determine the current tendencies in the change of religious views of young people by selected countries of the world, as well as to analyze such views among the student youth of Ukraine on the basis of the carried out survey. It is defined that on a global scale there are significant changes in the structure of believers and in the distribution of the population of countries according to beliefs. A large number of both adults and young people refuse religiosity. This tendency is observed in America and many European countries. Especially among young people it becomes popular to be an atheist. The decrease in religiosity also means a decrease in the frequency of visits to religious institutions and practicing prayers. On the other hand, there are countries with a very high level of believers. These are, first of all, religious centers such as Italy and Israel. It is prognosticated that the fertility rate of women of different religions and the age distribution of religious groups will undergo radical changes. The increase in the birth rate among Muslims will lead to the fact that the number of Muslims in the world in 30 years will approach the number of Christians. At this, the number of adherents of other religions will begin to decline, and their average age will grow rapidly. The analysis, carried out in the course of the research of the views of student youth of Ukraine, showed that most of them are believers and orthodox. At the same time, religions and cults that have been popularized by films and TV series are becoming popular. It is determined that most parents of students are also believers and orthodox. Still, the number of believing parents is greater than the number of believing students. It is determined that the majority of students choose the religion of both parents, which indicates the significant influence of parents on the religious views of students. It is defined that believing students have fewer bad habits, and they are much more likely to participate in charitable projects and events.

Published: March 2022

The article substantiates that concession is an effective instrument for the implementation by countries of social projects aimed at solving the urgent needs of territorial communities in the context of the COVID-19 pandemic. It is emphasized that the application of concession activities allows countries to remain the owner of objects, while maintaining administrative and control functions. The peculiarities of application of public-private partnership models under the concession agreement are presented. The foreign experience of implementation of concession projects in the social sphere is generalized, in particular, successful practices of attracting investments in the conditions of financial decentralization are considered. It is determined that the most popular areas for the implementation of concession projects are transport (34%), environment (16%), education (14%), telecommunications (7%), healthcare (5%), and other sectors (24%). It is specified that concession activities abroad, as a rule, are regulated by separate legislation, the cooperation of the public and private sectors is based solely on contractual relations, according to which the private operator is guaranteed to receive remuneration for the work performed or services provided from a public organization and/or direct users. Based on the carried out research, the reasons for the widespread use of concession as a form of public-private partnership in different countries are determined, among which the main are: more effective management of projects on the part of the private sector; lack of financial resources of the State and the willingness of the concessionaire to take most of the risks from the implementation of large-scale infrastructure projects. Concessional shortcomings are also presented, which include: lack of professional management experience at the regional and local levels from private partners who implement projects for the first time; significant level of financial risk to the private sector, including the likelihood of bankruptcy; political and socioeconomic situation in the world due to the consequences of the COVID-19 pandemic. Upon the grounds of a generalization of world experience, the main directions of monitoring the impact of COVID-19 on concession projects are allocated, which can assist in determining the appropriate level of actions that can be taken by governments.

The article is aimed at covering the methodological possibilities of the theory of political markets for making research of the current macroeconomic policy. The theory of political markets in the contemporary conditions is one of the most effective methodological instruments for researching the mechanisms of macroeconomic policy implementation both within terms of individual countries and in the field of international economic relations. Analyzing, systematizing and generalizing the scientific works of many scholars, the authors combined the analysis of officially declared procedures for making relevant political decisions with real informal mechanisms for the implementation of rent-oriented behavior of any of the political entities – both personified and those who «hide» behind the relevant groups of influence, which are created specially to conceal such personal influence. As a result of the research, two directions of application of the theory of political markets are allocated to study the peculiarities of the regulatory economic activity of the modern State. First, it is an analysis of the interaction of the main internal political actors – participants in the struggle for redistribution of public goods: politicians (whose powers depend on the results of elections); officials (whose powers depend on their appointment to office); voters (who «sell» their votes in exchange for favorable further decisions of politicians) and organized pressure groups (lobbyists). Secondly, it is a study of the regulatory role of the national State in international economic relations. A perspective direction of further scientific research in this plane is the development of a theoretical and methodological instrumentarium for quantitative assessment of the scale of redistribution and the size of losses of social welfare on the basis of the economic-statistical and expert assessments.

The purpose of the article is to deepen the theoretical and applied principles of researching the essence of the concept of «FinTech innovations» and their classification features. According to the results of the research, scientific approaches to understanding the essence of the term FinTech are evaluated. The versatility and varied meaningful load of this term indicates various differences and peculiarities of determining this category in scientific sources. Scholars interpret FinTech as innovative technologies and business models as technology, industry sector, services, etc. Each of the presented definitions shows their main feature, which is that FinTech really cannot work without using digital technologies. We are certain that FinTech is a technology used by financial services to help companies manage financial assets with use of special software, including new applications, apps, and business models. The origin of the term FinTech, which is a relatively new industry not only in Ukraine but also around the world, is also examined. It is determined that in the economic literature this term arose in the early 1990s, when development of the Internet started. FinTech’s growing popularity began in 2008, when the global financial crisis forced financial companies to cut costs. It is determined that the multi-level and multi-dimensional impact of FinTech innovations on the transformation of the financial services market creates the need to conduct the typologization of FinTech on various classification grounds. It is specified that the basis of the classification features of FinTech services should be their division according to the types of financial services they perform (payments, transfers, foreign exchange transactions, loans, savings, lending, insurance, investments, etc.).

Digitális bölcsészet a könyvtárban: elvek és projektek
Authors: Koltay Tibor
Published: March 2022

Hazai folyóiratokban és különösen a TMT hasábjain számos tanulmány jelent már meg a digitális bölcsészethez kötődő könyvtári témákról, így természetét már sokan ismerhetik. Mindazonáltal érdemes leszögeznünk, hogy ez a tudományág nemcsak olyan tevékenységek és projektek köre, amelyek a digitális technológiáknak a humántudományi kutatásokban való felhasználásával kapcsolatosak.1 Sokan ugyanis ennél többnek látják, ezért joggal tekintenek rá, mint együttműködésen alapuló, új formájú, több tudományterületet érintő kutatási, oktatási és publikációs tevékenységrendszerre, amely intézményi hátteret biztosít ahhoz, hogy – a könyvtárak és a könyvtárosok bevonásával – ezek a célok megvalósuljanak.2 Ennek megfelelően, ez a tanulmány főként az Amerikai Egyesült Államok könyvtárosainak bő két évtizedes elképzeléseire és tapasztalataira koncentrál, de merít az Európai Unió, Nagy-Britannia, és Kanada könyvtárainak tapasztalataiból is.
