Media aspects of the relationship between politics and sports using the example of the Russian Federation’s exclusion from international competitions
Authors: Sergienko A. E. 
Published: July 2024

RELEVANCE. The relationship between politics and sports is a pressing issue, since political contradictions between states are reflected in sports. Major sporting events are not just competitions between athletes, but also fierce political struggles. Through professional sports with the help of various media technologies, it is possible to influence global society and achieve geopolitical results. The relationship between elite sports and politics is considered using the example of the exclusion of Russian sports from international competitions and materials about this in the media.MATERIALS AND METHODS. Materials from foreign media have been studied on the topic of removing Russia from big-time sports, depriving it of state symbols, removing Russian athletes from international competitions due to disagreement with the political course of the authorities of the Russian Federation, and the introduction of so-called sanctions in the field of sports. The study was based on a comparative historical method, which helps to consider the dynamics of the development of relations between Russian sports and the political course of Western countries. The theoretical basis was the work of domestic and foreign researchers of the history and theory of sports. Content analysis was also used to study materials from Russian and foreign media with the aim of determining the attitude of foreign states towards Russian sports and its oppression in the international sports arena from 2014 to 2024.RESULT AND DISCUSSION. An analysis of foreign media materials confirms that pressure on Russian sports is being exerted by Western countries due to their disagreement with the political course of the Russian Federation. An analysis of sources showed that Western media agree on the issue of sanctions against Russian sports: they support the introduction of restrictions against Russian sports, but at the same time they call such measures an instrument of geopolitics, an instrument of “containing Russia”. This confirms the politicization of sports through the media.CONCLUSION. Analyzing the content of publications in both foreign and Russian media, we can conclude that pressure on Russian sports and members of the Russian national team began to intensify after the victory of the Russian team in the team event at the Olympic Games in Sochi 2014 and after the Republic of Crimea joined the Russian Federation . After the Russian Armed Forces launched a special military operation in Ukraine, even more sanctions and restrictions were introduced against Russian sports, and Russia was actually excluded from international sports. The author believes that the pressure on Russian sports will only increase.

Published: July 2024

RELEVANCE. In the conditions of constant, constantly changing wars, hostilities and armed conflicts, the role of military journalists, or war correspondents, who broadcast to the whole world from the battlefield, transmit timely and high-quality information from battlefields. These are professionals who are subject to many demands in terms of psychological qualities, resilience and tolerance for uncertainty. A person who does not possess such qualities cannot perform this extremely dangerous and traumatic work. In addition, military journalists are under pressure in modern information and communications conditions, which makes their already difficult work more difficult. At the same time, at the moment there is very little research on the topic of what specific qualities and abilities war correspondents should have to successfully carry out their professional activities. The purpose of the study is to study the factors of resilience and tolerance of uncertainty among military journalists.MATERIALS AND METHODS. An empirical study was conducted on the resilience and tolerance of uncertainty of 54 war correspondents and 50 journalists who are not involved in covering military events. We studied used the methods of “Vitality Test” by D.A. Leontyev and E.I. Rasskazova and “Uncertainty Tolerance Scale” by T.V. Kornilova.RESULT AND DISCUSSION. Statistically significant differences in indicators of resilience and tolerance to uncertainty were identified between groups of war correspondents and journalists, and significant relationships between indicators of resilience and tolerance to uncertainty in groups of war correspondents and journalists were identified and described.CONCLUSION. The conducted research makes it possible to form a picture of what personal characteristics war correspondents have and to highlight those traits that help them cope with dangerous and stressful working conditions

Abstract

Background
Globally, malaria is the major public health disease caused by plasmodium species and it is a mosquito-borne disease caused by a protozoan parasite belonging to the genus Plasmodium. The largest number of malaria cases and deaths are reported from the WHO African region mainly, Sub-Saharan Africa, each year. The aim of the study was to assess the ten-year trend of malaria in Maraki Health Center, Gondar Town, northwest Ethiopia.
Methods
A retrospective study was carried out at Maraki Health Center. Ten-year (2012–2021) blood film results were extracted by reviewing the laboratory logbook. A chi-square test was used to describe associations between malaria cases and different variables.
Result
In a ten-year period, 15,978 blood films were requested for malaria diagnosis, of whom 57.5% were from males. About 68.0% fell under the age group of 15–45 years old. The overall prevalence of malaria was 25.2% (n = 4019) (95% CI: 23.83–26.59). Plasmodium falciparum was the dominant malaria species over the ten-year period. The highest peaks of total malaria cases were observed in 2012 and in October, and the lowest peaks were observed in 2016 and April (mean annual case = 401.9). The highest and lowest peaks of P. falciparum cases followed a similar pattern to the total malaria cases. The highest and lowest peaks of P. vivax cases were observed in 2012 and 2018, respectively. There was a statistically significant year and monthly variation of malaria cases (P < 0:001). Malaria was reported in both sexes and all age groups, of which males and the age group 15–45 years old comprised the maximum number of malaria cases (P < 0:001).
Conclusion
Malaria continues to be an important public health concern in the study area. A significant fluctuation was observed over the ten-year period. Plasmodium falciparum was the predominant species, despite some annual P. vivax dominance. Uninterrupted efforts are still essential to decrease the burden of malaria to a level that has no more public health effects.

Abstract

Background
The global burden of heart failure, especially with reduced ejection fraction, is a significant health issue. Current guidelines stress the importance of optimal medication use to maximize patient outcomes. Nevertheless, a notable gap exists in implementing these guidelines worldwide. In Ethiopia, there is limited post-guideline data on the utilization and optimization of medications for patients with heart failure and reduced ejection fraction. This study aims to evaluate the patterns of utilization and drug optimization and associated factors of guideline directed medical therapy among these patients attending cardiac centers at selected public and private hospitals, Addis Ababa, Ethiopia.
Methods
A facility-based, cross-sectional study was conducted. Data were collected using a pretested, structured checklist. Data were edited and cleaned via Microsoft Excel 2016 and analyzed using SPSS version 26. Baseline demographic and clinical datawere summarized using descriptive statistics. Multiple logistic regression analysis was run to identify association between dependent and independent variables, by computing odds ratio and 95% confidence interval. A p-value < 0.05 was considered significant.
Results
A total of 404 patients were included in this study, with a response rate of 95.7%. Majority (222; 55%) were males, and patients’ age ranged from 17 years to 86 years with a median (inter-quartile range) of 56 (43.25–65) years. Overall, 46 (11.4%) were receiving quadruple therapy. ACEIs/ARBs, beta-blockers and MRA were given to 212(52.5%), 314 (77.7%), and238 (58.9%) patients, respectively. SGLT2Is were prescribed to only 109 (27%) patients. Age older than 65 years (AOR = 4.34; 95% CI = 1.59, 11.89), history of previous hospitalization (AOR = 2.50; 95% CI = 1.21, 5.15) and taking < 5 medications (AOR = 9.6; 95% CI = 2.79, 33.07) were associated with GDMT underutilization.
Conclusion
There is a large gap in GDMT implementation, with majority of the patients having either underutilization or under-dosing, particularly those older than 65 years, with history of previous hospitalization and taking < 5 medications. Thus, efforts should be directed to design customized guidelines along with institution of sensitization and training programs while also considering multidisciplinary care.
The Targeting Incidence of Brazil’s Vale Transporte transit subsidy scheme
Authors: Gómez-Lobo Andrés , González Vileydy , Sanchez Santiago 
Published: July 2024

Abstract

We evaluate the targeting properties of the Vale Transporte scheme in Brazil, one of the oldest and most iconic transit subsidies in the Latin American region. We use household survey data for 26 metropolitan areas to calculate the Concentration Index and the Ω Index to determine whether benefits are accruing to workers belonging to low-income households. The results indicate that this program is badly targeted. The Concentration Index is negative in only 7 of the 26 metropolitan areas, indicating a regressive incidence of this benefit in most cities. Likewise, the Ω Index indicates that only in 3 metropolitan areas is the targeting incidence mildly progressive when the target population is defined as workers belonging to the poorest 40% of households in each city. The reason behind these results is that only formal sector workers are eligible for this benefit while many low-income individuals work in the informal sector in Brazil. In addition, since this subsidy is paid for by employers it is reasonable to expect compensating equilibrium wage effects in the formal labor market. We present evidence that suggests that this may have occurred.

Abstract

Copper is a trace element in plants and animals whose importance can be understood due to its role in different essential metabolic processes. Anthropogenic activities such as agriculture and mining are potential sources of pollution due to the emission of copper into the environment. Brazilian legislation ties soil quality to guideline values, among which the Prevention Value indicates the critical environmental limit for trace elements. The aim of this study was to obtain PVs for copper for two subtropical soils (Cambisol and Nitisol), given that the pedological richness was not considered when deriving the PVs contained in the federal normative. Reproduction assays followed ISO guidelines with the earthworm species Eisenia andrei and Perionyx excavatus, the enchytraeids Enchytraeus crypticus and E. bigeminus and the springtails Folsomia candida and Proisotoma minuta. Results showed that the sensitivity of the organisms was greater in Cambisol. The most sensitive species were the earthworms, especially P. excavatus (EC50 = 67.83 in Cambisol; EC50 = 264.96 in Nitisol). The springtails, on the other hand, were the least sensitive to contamination. These findings reinforce the need to include organisms from different ecological groups in ecotoxicological assessments. It was also observed that the PV adopted in federal legislation (= 60 mg kg-1) is in fact protective for the species and soils we evaluated, since the PVs we obtained based on the EC50 were 346.74 mg kg-1 in Nitisol and 134.05 mg kg-1 in Cambisol. It is important to note that our results do not exclude the need for evaluations with other subtropical soils, given the influence of their properties on the toxicity and bioavailability of copper to soil organisms.

Abstract

Ischemia-reperfusion injury (IRI) is a major event in renal transplantation, leading to adverse outcomes. Bone marrow mesenchymal stem cells (BMSCs) are novel promising therapeutics for repairing kidney injuries. The therapeutic efficacy of BMSCs with ISL1 overexpression in renal IRI and its underlying mechanism need to be investigated. The unilateral renal IRI rat model was established to mimic clinical acute kidney injury. Rats were injected with PBS, BMSCs-Scrambled or BMSCs-ISL1 via the tail vein at the timepoint of reperfusion, and then sacrificed after 24 h of reperfusion. The administration of BMSCs-ISL1 significantly improved renal function, inhibited tubular cells apoptosis, inflammation, oxidative stress in rats. In vitro, HKC cells subjected to H2O2 stimulation were pretreated with the conditioned medium (CM) of BMSCs-Scrambled or BMSCs-ISL1. The pretreatment of ISL1-CM attenuated apoptosis and oxidative stress induced by H2O2 in HKC cells. Our proteomic data suggested that haptoglobin (Hp) was one of the secretory proteins in ISL1-CM. Subsequent experiments confirmed that Hp was the important paracrine factor from BMSCs-ISL1 that exerted anti-apoptotic and antioxidant functions. Mechanistically, Hp played a cytoprotective role via the inhibition of ERK signaling pathway, which could be abrogated by Ro 67-7476, the ERK phosphorylation agonist. The results suggested that paracrine action may be the main mechanism for BMSCs-ISL1 to exert protective effects. As an important anti-apoptotic and antioxidant factor in ISL1-CM, Hp may serve as a new therapeutic agent for treating IRI, providing new insights for overcoming the long-term adverse effects of stem cell therapy.

Abstract

Introduction
: Red blood cell distribution width (RDW) has recently been introduced as an important related factor in surveying prognosis of chronic diseases. This study was performed to assess the relationship between RDW and cardiac function before and after congenital heart disease surgery in children.
Method
Seventy-six children with congenital heart disease (CHD) requiring surgery admitted in Modarres Hospital pediatric cardiology ward were enrolled in this cross-sectional descriptive study. Blood samples were taken for RDW determination. Two-dimensional, M-mode, Doppler flow velocity and Tissue Doppler Imaging (TDI) were applied to evaluate cardiac function by echocardiography on the day following operation.
Results
There was no relationship between Preoperative RDW levels and early postoperative heart function except for increased Aortic Velocity Time Integral (VTI) and Mitral Valve Systolic Velocity (MV S′) noted in patients with higher RDW percents. Also, patients with higher RDW showed a longer intra-operative pump time and mean ICU stay.
Conclusion
Higher RDW levels may predict longer duration of surgery and ICU stay in pediatric cardiac surgery, however it has no relationship with cardiac function in the early postoperative period.

Abstract

Air pollution impacts on human health are of serious concern in northern India, and over the Delhi National Capital Region (NCR) in particular. The Kharif crop residue burning (CRB) is often blamed for degradation of Delhi-NCR’s seasonal air quality. However, the concentration of fine particulate matter (PM2.5) remained stable in Delhi, while the fire detection counts (FDCs) from satellites over Punjab and Haryana declined by 50% or more during 2015-2023. We further analysed measurements of PM2.5, carbon monoxide (CO) and related parameters in Delhi-NCR, Haryana and Punjab from a network of 30 low-cost sensors (CUPI-Gs) in a selected period (September–November) of 2022 and 2023. Measured PM2.5 showed lower concentration in 2023 compared to 2022 at Punjab and Haryana sites, in compliance with FDC reductions. We have conducted airmass trajectories, particle dispersion and chemistry-transport model simulations to depict the formation of air pollution events from CRB emissions. Using model sensitivity simulations, we estimated meagerly ~14% of PM2.5 in Delhi-NCR was contributed directly by the emissions from CRB in Punjab during October-November 2022. Model-observation comparisons of PM2.5, and day-night variations of PM2.5 and CO suggest emissions from incomplete combustion dominate in Delhi-NCR, which explains the effectiveness of the Graded Response Action Plan (GRAP).

Abstract

Sugar industries are among the oldest food processing factories. Regrettably, main waste from sugar industries, are discharged without treatment in the environment. There are many wastes from raw to final product in sugar processes. Industrial waste requires proper management; otherwise, it causes a major eﬀect on the environment. Molasse is one of the wastes from the sugar industry. However, it also has the potential to be transformed into polyhydroxyalkanoate (PHA) via fermentation. This approach could reduce waste and solve an environmental pollution. In this study, a fermentation was conducted in shake-flask with Cupriavidus Necator. Three types of pretreatments of molasse were conducted to increase PHA production: i) sulfuric acid pretreatment; ii) enzymatic pretreatment and iii) pretreatment with activated carbon. Molasse pretreated with enzyme, incubated in a water bath for 5 h (60 °C, 150 rpm), allows to accumulate up to a maximum of 8.20 g/L cell dry mass (CDW), with a PHA content of 71.79 wt%. The use of molasse for PHA production, has the potential to drive sugar industry toward a circular bioeconomy. Because PHB obtained will use to produce bioplastic bag, for containing sugar.

Abstract

Engagement in shared activities between parents and children is potentially compromised by the pervasive use of digital screens in familial contexts. In this randomized trial in 326 parent-child dyads nested in 87 families, we investigated the effects of limiting screen use in parents and children on the amount of synchrony in physical behaviors and family cohesion. Families were randomly assigned to wither undergo an extensive screen media reduction intervention or to control. For seven days at baseline and follow-up, parents and children each wore two accelerometers, positioned on the thigh and trunk, 24 hours/day, enabling the second-by-second classification of their physical behaviors. Time-series sequence analysis of physical behavior revealed significant enhancements in dyadic synchrony for the screen reduction group. In shared leisure time, the between-group mean difference in change favored the screen reduction group, with a -0.18 point (95%CI -0.27 to -0.10) decrease in time-warp edit distance dissimilarity score and a 32.9 min/day (95%CI 16.0 to 49.9) of more direct matched activity. Additionally, parents in the screen reduction group reported enhanced family communication, more collaborative tasks, and engagement in new shared activities. Our findings highlight the potential benefits of reducing screen time for improving parent-child behavioral synchrony and familial cohesion.
