    PURPOSE: Theoretical and empirical research on corporate sustainability focuses on the relationship between environmental, social, and governance (ESG) performance and profitability or market value; little attention is given to describing their effect on dividend policy. Therefore, the main purpose of this paper is to address the research gap by identifying the relationship between corporate sustainability performance and the stability of dividend payouts. To achieve this goal, we formulated a general research hypothesis that there is a positive link between an enterprise’s ESG performance and its propensity to pay stable dividends. This research hypothesis is operationalized by the following five specific hypotheses: (1) the link between the overall ESG score and the propensity to pay stable dividends is positive; (2) the link between the environmental pillar score and the propensity to pay stable dividends is positive; (3) the link between the social pillar score and the propensity to pay stable dividends is positive; (4) the link between the governance pillar score and the propensity to pay stable dividends is positive; (5) the link between the ESG controversies score and the propensity to pay stable dividends is positive. METHODOLOGY: The hypothesis was empirically verified using a logistic regression model among the world’s largest non-financial enterprises listed in the Global 500 of 2021 for the years 2012–2021. The specifications of the general model include sustainability variables such as environmental, social, and governance pillar scores, as well as the ESG controversies score, which measures an enterprise’s exposure to environmental, social, and governance controversies and negative events reflected in global media. The financial ratios, such as a return on assets, current ratio, and debt-to-equity ratio, are considered control variables in the model specifications. The research was extended by implementing descriptive statistics and Pearson correlation coefficients. All required financial and sustainability data were retrieved from the London Stock Exchange Group (LSEG) Eikon database. FINDINGS: The results of the estimation revealed that: (1) the effect of integrated ESG activities on payout stability is statistically significant and negative only in model specifications without the ESG controversies; (2) the effect of the environmental dimension is statistically significant and negative only when other particular ESG pillars are not considered; (3) the effect of the social dimension is statistically significant and negative, only when the governance dimension and the ESG controversies are not considered together in the same model specification; (4) the effect of the governance dimension is statistically significant and positive only if other particular pillars are considered together in one model specification, both with and without the ESG controversies; (5) the effect of the ESG controversies is statistically significant and positive in each model specification. Therefore, the general research hypothesis cannot be confirmed because only the fifth specific research hypothesis can be positively verified in all model specifications. IMPLICATIONS: Further research should be conducted on the relationship between corporate sustainability performance and dividend policy. It should consider not only commonly applied ESG scores but also the ESG controversies score, which was statistically significant in this research. Governments and international organizations should cooperate with companies that provide ESG data to make ESG scores, including the ESG controversies score, publicly available to all stakeholder groups, which would help to reduce the information gap. Managers should pay more attention to increasing the visibility of ESG initiatives from the perspective of risk, which they allow to avoid controversies in particular corporate sustainability dimensions. ORIGINALITY AND VALUE: The value added of this paper is that it investigates the relationship between ESG performance and payout policy, which was not thoroughly explored in previous studies, especially in the context of an enterprise’s controversial ESG activities. To fill the research gap in the literature, the authors incorporated the ESG controversies score as an independent variable in the model specifications, which is a novelty in research on dividend policy

    Introduction: A rapid outbreak of SARS-CoV-2 in the past few years caused a significant increase in the number of upper respiratory tract infections throughout the world. Numerous public health institutions tried to control the COVID-19 pandemic, including mandatory mask wearing, vaccinations, increased frequency of using disinfectants or compulsory lockdowns. Lockdown interventions were necessary, although they lead to insufficient, comparing to the international recommendations, levels of physical activity, which could trigger an elevated susceptibility to diseases of affluence. Purpose: Regular aerobic exercise may suppress inflammation, boost innate immunity and result in enhanced protection against viral infections. This review aims to show the relationship between level of physical activity and the risk and severity of COVID-19 infectio

    Get PDF
    Introduction Anemia and iron deficiency are common comorbidities in population with heart failure. Their association with unfavorable prognostic outcomes and diminished quality of life underscores the imperative need for accurate diagnosis and efficacious treatment interventions. In recent years numerous treatment options have been explored in clinical trials, aimed at addressing the multifaced aspects of these concurrent conditions. Summary In patients with heart failure effective treatment of anemia and iron deficiency has demonstrated enhancements in quality of life and exercise capacity. Findings from IRONMAN clinical study have prompted revisions in the latest guidelines from the European Society of Cardiology. The imminent release of results from two ongoing trials holds the potential to reshape the therapeutic landscape for treating individuals with heart failure and iron deficiency. Nevertheless, there is no explicit evidence that studied interventions could improve morbidity or risk of hospitalizations

    Microvascular angina – an abstruse path to diagnose and to treat – a review of literature

    Get PDF
    Introduction: Chronic coronary syndrome is predominantly related to the atherosclerotic obstruction of the coronary artery or arteries. However, this phenomenon is not the only causative factor in this disease. It is usually forgotten, that there is a possibility of ischemia of the cardiac muscle with no obstruction found in the main vessel. The trigger of such pathology might be underlying in the microcirculatory system and the inappropriate dilation or constriction of those small vessels, which results in insufficient blood supply to the cardiomyocytes, similarly to the typical obstructive coronary artery disease. In this article we are willing to show that such dysfunction poses a great danger to the health and life and therefore we should be able to properly diagnose and treat it. Purpose of the work: The aim of this review of up-to-date literature is to raise awareness among both doctors and patients about the phenomenon of coronary artery disease but with no significant obstruction in the vessels supplying the cardiac muscle. The common cause of such condition is coronary microvascular dysfunction, that leads to a disease called microvascular angina. Our purpose was to reveal, how dangerous to the health of the patients this could be and therefore how essential it is to provide a proper diagnose and management. In addition, we have noticed a need for a summary of what has already been discovered on this topic, available therapeutic methods and future perspectives

    Polish statement on food allergy in children and adolescents

    An adverse food reaction is defined as clinical symptoms occurring in children, adolescents or adults after ingestion of a food or chemical food additives. This reaction does not occur in healthy subjects. In certain individuals is a manifestation of the body hypersensitivity, i.e. qualitatively altered response to the consumed food. The disease symptoms observed after ingestion of the food can be triggered by two pathogenetic mechanisms; this allows adverse food reactions to be divided into allergic and non-allergic food hypersensitivity (food intolerance). Food allergy is defined as an abnormal immune response to ingested food (humoral, cellular or mixed). Non-immunological mechanisms (metabolic, pharmacological, microbiological or other) are responsible for clinical symptoms after food ingestion which occur in non-allergic hypersensitivity (food intolerance). Food allergy is considered a serious health problem in modern society. The prevalence of this disorder is varied and depends, among other factors, on the study population, its age, dietary habits, ethnic differences, and the degree of economic development of a given country. It is estimated that food allergy occurs most often among the youngest children (about 6-8% in infancy); the prevalence is lower among adolescents (approximately 3-4%) and adults (about 1-3%). The most common, age-dependent cause of hypersensitivity, expressed as sensitization or allergic disease (food allergy), are food allergens (trophoallergens). These are glycoproteins of animal or plant origine contained in: cow's milk, chicken egg, soybean, cereals, meat and fish, nuts, fruits, vegetables, molluscs, shellfish and other food products. Some of these allergens can cause cross-reactions, occurring as a result of concurrent hypersensitivity to food, inhaled or contact allergens. The development of an allergic process is a consequence of adverse health effects on the human body of different factors: genetic, environmental and supportive. In people predisposed (genetically) to atopy or allergy, the development of food allergy is determined by four allergic-immunological mechanisms, which were classified and described by Gell-Coombs. It is estimated that in approximately 48-50% of patients, allergic symptoms are caused only by type I reaction, the IgEmediated (immediate) mechanism. In the remaining patients, symptoms of food hypersensitivity are the result of other pathogenetic mechanisms, non-IgE mediated (delayed, late) or mixed (IgE mediated, non-IgE mediated). Clinical symptomatology of food allergy varies individually and depends on the type of food induced pathogenetic mechanism responsible for their occurrence. They relate to the organ or system in which the allergic reaction has occurred (the effector organ). Most commonly the symptoms involve many systems (gastrointestinal tract, skin, respiratory system, other organs), and approximately 10% of patients have isolated symptoms. The time of symptoms onset after eating the causative food is varied and determined by the pathogenetic mechanism of the allergic immune reaction (immediate, delayed or late symptoms). In the youngest patients, the main cause of food reactions is allergy to cow’s milk. In developmental age, the clinical picture of food allergy can change, as reflected in the so-called allergic march, which is the result of anatomical and functional maturation of the effector organs, affected by various harmful allergens (ingested, inhaled, contact allergens and allergic cross-reactions). The diagnosis of food allergy is a complex, long-term and time-consuming process, involving analysis of the allergic history (personal and in the family), a thorough evaluation of clinical signs, as well as correctly planned allergic and immune tests. The underlying cause of diagnostic difficulties in food allergy is the lack of a single universal laboratory test to identify both IgE-mediated and non-IgE mediated as well as mixed pathogenetic mechanisms of allergic reactions triggered by harmful food allergens. In food allergy diagnostics is only possible to identify an IgE-mediated allergic process (skin prick tests with food allergens, levels of specific IgE antibodies to food allergens). This allows one to confirm the diagnosis in patients whose symptoms are triggered in this pathogenetic mechanism (about 50% of patients). The method allowing one to conclude on the presence or absence of food hypersensitivity and its cause is a food challenge test (open, blinded, placebo-controlled). The occurrence of clinical symptoms after the administration of food allergen confirms the cause of food allergy (positive test) whereas the time elapsing between the triggering dose ingestion and the occurrence of clinical symptoms indicate the pathogenetic mechanisms of food allergy (immediate, delayed, late). The mainstay of causal treatment is temporary removal of harmful food from the patient’s diet, with the introduction of substitute ingredients with the nutritional value equivalent to the eliminated food. The duration of dietary treatment should be determined individually, and the measures of the effectiveness of the therapeutic elimination diet should include the absence or relief of allergic symptoms as well as normal physical and psychomotor development of the treated child. A variant alternative for dietary treatment of food allergy is specific induction of food tolerance by intended contact of the patient with the native or thermally processed harmful allergen (oral immunotherapy). This method has been used in the treatment of IgE-mediated allergy (to cow's milk protein, egg protein, peanut allergens). The obtained effect of tolerance is usually temporary. In order to avoid unnecessary prolongation of treatment in a child treated with an elimination diet, it is recommended to perform a food challenge test at least once a year. This test allows one to assess the body's current ability to acquire immune or clinical tolerance. A negative result of the test makes it possible to return to a normal diet, whereas a positive test is an indication for continued dietary treatment (persistent food allergy). Approximately 80% of children diagnosed with food allergy in infancy "grow out" of the disease before the age of 4-5 years. In children with non-IgE mediated food allergy the acquisition of food tolerance is faster and occurs in a higher percentage of treated patients compared to children with IgE-mediated food allergy. Pharmacological treatment is a necessary adjunct to dietary treatment in food allergy. It is used to control the rapidly increasing allergic symptoms (temporarily) or to achieve remission and to prevent relapses (long-term treatment). Preventive measures (primary prevention of allergies) are recommended for children born in a "high risk" group for the disease. These are comprehensive measures aimed at preventing sensitization of the body (an appropriate way of feeding the child, avoiding exposure to some allergens and adverse environmental factors). First of all, the infants should be breast-fed during the first 4-6 months of life, and solid foods (non milk products, including those containing gluten) should be introduced no earlier than 4 months of age, but no later than 6 months of age. An elimination diet is not recommended for pregnant women (prevention of intrauterine sensitization of the fetus and unborn child). The merits of introducing an elimination diet in mothers of exclusively breast-fed infants, when the child responds with allergic symptoms to the specific diet of the mother, are disputable. Secondary prevention focuses on preventing the recurrence of already diagnosed allergic disease; tertiary prevention is the fight against organ disability resulting from the chronicity and recurrences of an allergic disease process. Food allergy can adversely affect the physical development and the psycho-emotional condition of a sick child, and significantly interfere with his social contacts with peers. A long-term disease process, recurrence of clinical symptoms, and difficult course of elimination diet therapy are factors that impair the quality of life of a sick child and his family. The economic costs generated by food allergies affect both the patient's family budget (in the household), and the overall financial resources allocated to health care (at the state level). The adverse socio-economic effects of food allergy can be reduced by educational activities in the patient’s environment and dissemination of knowledge about the disease in the society

    Changes in Electricity Production from Renewable Energy Sources in the European Union Countries in 2005–2019

    Get PDF
    The policy related to the use of renewable sources is a key element of the energy policy executed in the European Union (EU). One of the targets set for 2050 is to increase the share of electricity in energy consumption to 50%, and 80% of electricity is to be generated from low-carbon sources. In recent years, the EU economies have significantly modified their electricity production, which raises the question of the scale of these changes. The aim of the presented analysis is to assess changes in the use of renewable sources for electricity production in the EU countries in 2005–2019. Gini coefficient and k-mean are applied in the analysis. The conducted research shows that EU countries, in line with the energy policy assumptions, have both increased the share of renewable sources in energy production, especially in electricity production, as well as increased the diversity of used renewable sources. The results also indicate a vast diversity in terms of the use of such sources for the production of renewable electricity in the EU. This indicates that the energy transition is being implemented by EU countries with individual country-level approaches. Nonetheless, a variety of the EU’s both support and restrictive measures are of considerable importance for the ongoing energy transition

    Private households are an important group of energy consumers. Based on Eurostat data, their energy consumption constituted 30% of the final consumption of energy use across the European Union in 2021. The cost of energy is one of the main components of household budgets; thus, the prices provided by energy carriers have a significant impact on energy consumption. The price offered to the final consumer consists of three components: the price of energy and its supply, network costs, and taxes and levies. The values of the three components, however, depend on several factors, among which the structure of the energy markets and energy policies in individual EU countries play a key role. This work aimed to analyze and assess the structure of electricity prices offered to households across EU countries in the years 2019–2021. The differences and similarities between the pricing policies of selected products in the EU and their impacts on households’ purchasing capacity were captured and a non-pattern classification method (k-means) was applied as a research tool. The results indicated that the heterogeneity of the electricity price structure increased significantly over the period analyzed. This may be a consequence of the use of strongly differentiated tools to mitigate electricity price increases and the steps being taken towards low-carbon economies

    Get PDF
    Introduction: Neoplasmatic diseases during pregnancy are relatively rare, with the incidence of approximately 1/1000 pregnancies. The symptoms of neoplasmatic processes are unspecific and often mirror physiological changes during pregnancy. Chemotherapy is the main therapeutic management of non-Hodgkin lymphomas. The strategy of the treatment and its influence on the course of pregnancy remain controversial. Aim: The aim of this study was to present the case of a pregnant woman with non-Hodgkin lymphoma. Case report: We described the case of a 27-year-old pregnant nullipara with anemia, breathlessness, cough and general weakness with diagnosed diffused large B-cell lymphoma. During pregnancy the patient received six cycles of CHOP chemotherapy without any serious complications. On 37 week of gestation the caesarean section was performed. Conclusions: Coexisting non-Hodgkin lymphomas and pregnancy are seldom the case and the treatment requires complex chemotherapy

    Cornelian Cherry Iridoid-Polyphenolic Extract Improves Mucosal Epithelial Barrier Integrity in Rat Experimental Colitis and Exerts Antimicrobial and Antiadhesive Activities In Vitro

    Background and Aims. Inflammatory bowel disease pharmacotherapy, despite substantial progress, is still not satisfactory for both patients and clinicians. In view of the chronic and relapsing disease course and not always effective treatment with adverse effects, attempts to search for new, more efficient, and safer substances are essential and reasonable. This study was designed to elucidate the impact of cornelian cherry iridoid-polyphenolic extract (CE) and loganic acid (LA) on adherent-invasive E. coli growth and adhesion in vitro and to assess the effect of pretreatment with CE or LA on the course of intestinal inflammation in rat experimental colitis compared with sulfasalazine. Methods. Antibacterial and antiadhesive activities of CE and LA were assessed using microdilution, Int407 cell adherence, and yeast agglutination assays. The colitis model was induced by 2,4,6-trinitrobenzenesulfonic acid. Studied substances were administered intragastrically for 16 days prior to colitis induction. Body weight loss; colon index; histological injuries; IL-23, IL-17, TNF-α, and chemerin levels; and STAT3, Muc2, and TFF3 mRNA expression were evaluated. Results. Only CE exerted antimicrobial and antiadhesive activities in vitro and alleviated colonic symptoms. CE coadministrated with sulfasalazine was more effective than single compounds in reversing increased concentrations of TNF-α, IL-17, and chemerin and decreased Muc2 mRNA expression. Conclusions. CE exerted a protective effect against experimental colitis via impaired mucosal epithelial barrier restoration and intestinal inflammatory response attenuation and given concomitantly with sulfasalazine counteracted colitis in a more effective way than sulfasalazine alone, which indicates their synergistic interaction. The beneficial effect of CE may also be due to its bacteriostatic and antiadhesive activities
